Introduction
In cases of severe atopic dermatitis (AD) and lack of re-
sponse to topical treatment, it is recommended to consid-
er administration of the following: cyclosporine A (CyA) or
dupilumab, methotrexate (MTX), azathioprine (AZA), my-
cophenolate mofetil (MMF), glucocorticoids (GCs) [1–10].
Prior to administration of immunosuppressive treat-
ment it is recommended to:
conrm the diagnosis of AD;
• excluding:
– disease-exacerbating factors,
– possibility of infections,
– comorbidities,
– contact eczema.
Cyclosporine A (CyA) is recommended as the rst-line
drug in severe cases of chronic AD in adults. In children
and youths its application should be considered only in
severe AD cases by a physician with appropriate experi-
ence. Recommendations regarding the use of the drug
in children are based on results of single cohort stud-
ies and individual randomized cohort studies (o-label
recommendations) [3, 11, 12]. Cyclosporine A decreases
inflammation, area of lesions, and pruritus intensity,
as well as improves the quality of sleep. An initial rec-
ommended drug dose is 5 mg/kg body weight/day
with a reduction of 0.5–1 mg/kg body weight/day every
2 weeks, when clinical ecacy has been reached. Ben-
ecial eects of CyA include a decrease in pruritus and
skin inflammation, and is observed already within 2–
6 weeks of treatment introduction [3, 11, 12]. It is recom-
mended to administer CyA in cycles that last 12 weeks
on average. Discontinuation of the drug is associated
with recurrence of skin lesions within several weeks
since the discontinuation of the treatment, however, it
is assessed that condition of patients’ skin does not re-
turn to the same condition as before the CyA treatment
[11, 12]. Dose decrease should be considered with regard
to clinical ecacy. In some cases it may be recommended
to opt for a long-term treatment with the lowest clinically
eective dose [3]. The drug may also be administered in
a long-term continuous therapy. CyA treatment duration
depends on the clinical ecacy and drug tolerance, how-
ever, the treatment should not exceed 2 years and must
be accompanied with thorough monitoring of possible
serious adverse reactions. Despite the fact that many pa-
tients tolerate a much longer than 2 years therapy with
a low CyA dose, after 2 years of the CyA therapy is should
be attempted to discontinue the treatment or change the
drug to another one that is administered generally [3]. In
some patients a so-called weekend therapy is eective;
it allows for decreasing an accumulative dose. A close
monitoring of patients is recommended. Frequent ad-
verse reactions of CyA (e.g. nephrotoxicity, hypertension)
speak against the long-term AD treatment with CyA, and
3–6-month intervals are suggested [3].
Despite unquestionable ecacy of CyA in AD treat-
ment, the use of this drug is associated with the risk of
serious adverse reactions. Most of the side eects appear
during the therapy, and subside after the drug is discontin-
ued. In order to prevent them or decrease the risk for their
appearance, it is recommended to monitor the treatment
closely. Patients taking the drug should undergo regu-
lar exams with regard to arterial pressure and nephritic
parameters. The risk for nephrotoxic activity increases
when the drug dose exceeds 5 mg/kg body weight/day,
increased creatinine values are maintained, and in the el-
derly. Kidneys may be permanently damaged (tubulopathy,
vasculopathy) in individuals who take CyA continually for
over 2 years [12]. In short-term intermittent CyA therapy,
renal dysfunction is usually transient. The risk for occur-
rence of nephrotoxic activity is lower in children than in
adults. Less common adverse reactions occurring during
CyA therapy include neurological symptoms, such as head-
ache, convulsions, paraesthesia, as well as disorders of
the gastrointestinal tract, infections, gingival hypertrophy,
hypertrichosis, hyperlipidaemia, disorders in electrolyte
levels, an increased risk for developing skin cancers and
lymphoproliferative hyperplasia. Measurements of CyA
blood concentration during the therapy with this drug is
not required since CyA concentration correlated with ef-
cacy and toxicity only in a slight degree.
Despite the lack of clinical proofs, it is recommended
to discontinue CyA 2 weeks before planned vaccination,
and start taking it again 4–6 weeks after the vaccination
[2, 3]. During the CyA therapy, an eective UV protection
should be used.
Dupilumab is an IL-4/IL-13 receptor α antagonist and
the rst biological drug in the world registered for treat-
ment of moderate and server AD, which is not adequate-
ly controlled by recommended topical treatment or when
such treatment is not recommended.
Dupilumab may be used as the second-line treatment
in severe AD after the rst failure of general therapy. The
drug may be used with or without local glucocorticoste-
roids (GCs). Clinical studies conrmed its statistically sig-
nificant clinical efficacy with regard to improvements in
disease symptoms measured with the use of EASI (75%)
and IGA scoring systems, and an improvement with
4 points of pruritus evaluation according to Numeric Rat-
ing Scale (NRS) as compare with the placebo control group.
A decrease in sleep disorders, an improvement in quality
of life, and good drug tolerance were conrmed. The most
commonly observed adverse events included: local reaction
after subcutaneous drug administration, and conjunctivitis.
A high safety prole of the drug and lack of dose-dependent
toxicity were presented. The drug is administered accord-
ing to the following scheme: 600 mg in two injections with
300 mg, and then 300 mg subcutaneously every 2 weeks.
There is available data that indicates its long-term ecacy
and safety [13–15].

Part II. Systemic treatment and new therapeutic methods
131
Oral glucocorticosteroids (GCs) are allowed for AD
treatment with a limitation, mainly in adult patients, to
the period of 1 week, in rigidly selected cases, and in dis-
ease exacerbation periods [2, 3]. An equivalent of 0.5 mg
of prednisone/kg body weight should not be exceeded
[3]. In everyday practice (dierent from published clinical
study results) the most common reasons for discontinu-
ation of treatment involving oral GCs are: adverse reac-
tions, lack of treatment ecacy, lack of patient’s co-oper-
ation, or abandonment of treatment by the patient after
improvements in clinical condition have been achieved.
During 10-year observational studies of AD-patients in
the Netherlands, the lowest number of adverse reac-
tions was noted during the treatment of oral GCs (5%),
MMF (22%), and CyA (24%). More adverse reactions were
observed after the treatment with AZA (38%) and MTX
(41%) – these adverse reactions regarded the gastroin-
testinal track in most cases. Then, the treatment was not
eective in 15% of CyA and AZA cases, 20% of oral GCs
cases, 44% of MMF cases, and 65% of MTX cases [16].
Methotrexate, AZA, and MMF may be used o-label
in AD-patients if CyA is ineective or there exist contra-
indications for its use [3].
Methotrexate (MTX) is recommended for treatment
of severe AD cases resistant to other treatment methods.
It is highlighted that it is the second, after CyA, most fre-
quently used drug in treatment of severe AD. Referenced
literature included a number of reports on safety and ef-
cacy of MTX in AD. The studies most often regard adults.
There are also single reports on efficacy and safety of
MTX usage in children [16–19].
Currently MTX is recommended in AD treatment in
adults in doses similar to the ones used in treatment of
psoriasis, i.e. 10–20 mg/week. The drug may be used in
one dose once a week, but it is more often used in three
doses of 2.5–7.5 mg every 12 h once a week [17–19]. Other
authors recommend to use MTX in the dose of 7.5–25 mg/
week in adults, and 0.2–0.7 mg/kg/week in children [17].
The treatment is usually tolerated well, but it should be
remembered that severe adverse reactions may occur. It
is believed that frequency and intensity of adverse re-
actions is associated with the dose. Adverse reactions
were reported mainly after the use of large MTX doses.
More common ones included: hepatotoxicity, bone mar-
row suppression, pneumonocirrhosis, and renal insu-
ciency. Methotrexate is teratogenic – women and men
should use eective contraception during the treatment
and, according to SPC, for 6 months after its discontinu-
ation [16–19].
Azathioprine (AZA) is used o-label in treatment of
severe atopic dermatitis cases in adults resistant to other
treatment methods, i.e. when CyA is noneective or con-
traindicated. AZA may be also used o label in children
[3]. A precise mechanism of AZA in AD has not been fully
examined. In vitro studies suggest that AZA exerts sup-
pressive and toxic influence on Langerhans cells. It is
emphasized that AZA is really eective in AD treatment,
however, due to AZA’s mechanism, therapeutic eects
of the drug may be delayed. In some patients, full thera-
peutic eects are reached even after 12 weeks or later.
It is recommended to use AZA in the dose of 1–3 mg/kg
body weight/day. Prior to commencement of the treat-
ment, thiopurine methyl transferase (TPMT) activity
should be determined, since this enzyme participates in
metabolism of 6-mercaptopurine, and in individuals with
a congenital insuciency of this enzyme, an increased
myelosuppression may occur [3]. Thiopurine methyl
transferase gene mutations may inuence the ecacy
and safety of treatment with AZA. Measuring the TPMT
level allows for adjusting an individual dose to the pa-
tient, and decreasing the risk of bone marrow damage
[20–26]. Individual authors used the drugs in severe AD
in children and showed that it was effective. Toxic in-
uence exerted on the bone marrow was not observed
[24, 25]. Furthermore, it was showed that AZA not only
improves the clinical conditions, but also decreases the
level of total IgE in children and youths with AD [26].
Azathioprine shows a number of adverse reactions.
The most commonly observed include bone marrow
damage and disorders of the immune system. Moreover,
the following are also observed: vascular disorders (vas-
culitis), gastrointestinal disorders (nausea, emesis), and
disorders involving the liver. Therefore, it is necessary to
monitor transaminases and complete blood count dur-
ing the treatment. According to the summary of product
characteristics, within rst 8 weeks of treatment, com-
plete blood count examination should be performed once
a week. During a later treatment period, the frequency of
tests may be decreased to one test per month, and then,
to one test per 3 months. In case the level of leucocytes
or blood platelets drops below the normal limit, and in
case other adverse reactions occur, the drug dose should
be lowered.
While using AZA, patients should not be vaccinated
with vaccines containing live microorganisms. Since AZA
exhibits teratogenic activity, it should not be used dur-
ing pregnancy. Furthermore, the drug should not be used
during breastfeeding period. Azathioprine should not be
combined with UV – an eective protection against UV
should be used [3, 26].
Mycophenolate mofetil may be used o label in treat-
ment of adults with AD in the dose of up to 3 g/day if CyA
is ineective or contraindicated. Mycophenolate mofetil
may be used in treatment of children and youths with
AD. Mycophenolate mofetil is teratogenic – men and
women must use eective contraception [3].
Antihistamines
There is no sucient proof to use rst- and second-
generation antihistamines for treating pruritus in AD.
First-generation antihistamines may inhibit histamine

activity in subcortical regions of the central nervous sys-
tem, and simultaneously exert anti-pruritic and sedative
influence, what may be beneficial in case of patients
with AD, who have problems with falling asleep and
suer from sleep disorders. Second-generation antihis-
tamines are especially useful in patient with AD that
is accompanied by conjunctivitis or allergic rhinitis [3].
A higher specificity of the bond to histamine receptor
H1, a longer halife period, and hydrophilic structure of
second-generation antihistamines contributed to an in-
creased ecacy and safety of use of second-generation
antihistamines [7, 27].
Allergen-specic immunotherapy
Allergen-specic immunotherapy is the only causal
treatment for AD-patients. Indications for allergen-specif-
ic immunotherapy in AD-patients include cases with in-
sucient response to existing treatment and document-
ed allergy to IgE-dependent airborne allergens [3, 28–31].
Allergen-specic immunotherapy for AD shows consid-
erable clinical efficacy in treatment of patients with
signs of being allergic to both year-round and seasonal
airborne allergens, especially in patients allergic to one
allergen group [3, 31]. So far, clinical eects with the use
of allergen-specic immunotherapy in patients allergic to
dust mites and pollens have been documented best [30,
31]. There are no contraindications to deallergize patients
with AD or concomitant other atopic diseases, such as
allergic rhinitis or mild bronchial asthma [3, 31]. Eec-
tive allergen-specic immunotherapy depends on proper
patient qualication, proper choice of the vaccine com-
position, and proper execution of the therapy. Vaccine
composition should be based on results of a detailed
physical examination, interview, and reliable diagnostics
based on skin prick tests and measurement of serum
asIgE. Proper choice of vaccine composition, and the or-
der of their administration in cases of patients suering
from AD with polyvalent allergies determined the success
of allergen-specic immunotherapy. While planning the
therapy for AD-patients, allergological diagnostics should
not be limited to skin prick tests, but should be supple-
mented with measurement of asIgE levels for proper al-
lergens by means of brand new diagnostic methods, e.g.
component-resolved [29–31].
Adverse reactions occur mainly during an induction
phase of the allergen-specic immunotherapy, and are
of mild as well as transient nature. Most often they take
a form of erythema and skin oedema at site when the
vaccine was administered. Systemic reactions are less
common and occur as focal reactions distant from the
allergen administration site, or there are general symp-
toms. Exacerbations of rhinitis or asthma as well as
occurrence of skin pruritus and urticaria are observed.
Non-specic symptoms, such as increased temperature,
headaches, dizziness, fatigue, and muscle tiredness, are
less frequently reported. Individual cases can involve
a drop in arterial blood pressure, laryngeal oedema, or
even anaphylactic shock. Usually, adverse reactions of
allergen-specic immunotherapy are mild as well as tran-
sient, and include, rst and foremost, the skin. However,
while using allergen-specic immunotherapy, one should
always be prepared for a pharmacological intervention
and have anaesthesiologic protection [31]. This therapy
should be conducted systematically for at least 4–
5 years by an expert physician, with satisfaction of safety
requirements, and allowing for occurrence of adverse re-
actions [30, 31].
Probiotics
Probiotics were examined with regard to possible ap-
plication in AD treatment. A justication of the use of
probiotics is that bacteria they contain induce immu-
nological response type Th1 instead of Th2, what is to
inhibit production development of IgE antibodies. Some
reports show an enormous benet associated with the
use of probiotics in AD prevention and treatment. These
studies show inconsistent results and require to be con-
rmed [32–36].
Alternative treatment
Balneotherapy with thermal water may be taken into
consideration in treatment of mild and moderate AD. Co-
hort studies show that balneotherapy with thermal water
with/without phototherapy may be eective in mild and
moderate AD [3, 37].
There is no proof of ecacy for acupuncture, acupres-
sure, bioresonance, Chinese herbs, homeopathy, and mas-
sage/aromatherapy in the treatment of AD [3]. Yet, a risk
for developing a secondary contact allergy is observed
after e.g. application of lavender oil that contains up to
40% of linalool [38, 39]. Acupuncture, acupressure, biores-
onance, homeopathy, and Chinese herbs are not recom-
mended in AD treatment [3].
New methods of therapy
A phosphodiesterase 4 (PDE4) inhibitor for topical
application in AD therapies that since 2016 has been
available only in the US. In clinical studies including
children above the age of 2 with mild and moderate
AD, crisaborole was used twice a day for 4 weeks with
the following results: a reduction of lesions on IGA scale
was achieved, and pruritus was signicantly reduced
after 2 days of treatment. The studies lasted 48 weeks
and conrmed ecacy and safety of crisaborole. Ob-
served adverse reactions included pain, and infections
at the sited of administration [40–42].
Currently, a number of new drugs for AD therapies
are at the clinical study phase, including biological drugs,

phosphodiesterase 4 (PDE4) antagonists, and protein ki-
nase inhibitors (JAK) [43–46]. It appears that personalized/
individual medicine is the future of AD therapies. On the
basis of measuring biomarkers specic for particular dis-
ease endotypes, it will be possible to qualify patients to
proper therapeutic groups, and implement eective tar-
geted treatment [47].
Conclusions
While treating AD-patients the following factors are
of key importance: experience and close co-operation
with patients and/or their families, education, prophy-
laxis, avoidance of factors exacerbating the disease, re-
storing dysfunctional skin barrier functions, containing
pruritus, and elimination of inammatory lesions as well
as skin infections. The patients require frequent multi-
specialist consultations, and in serious cases, hospital-
izations at wards dealing with treatments of this disease.

... The most widely adopted guidelines for AD management were published by the American Academy of Dermatology in 2014; however, these predate the approval of dupilumab, leaving a gap of evidence-based, practical recommendations for up-todate management of adult AD (8,9). A number of recent clinical practice guidelines (CPGs) and recommendations from various groups were developed internationally to incorporate dupilumab in treatment algorithms (30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40)(41)(42). To the best of our knowledge, the quality of these CPGs' methods and development processes have not yet been assessed. ...
... The median score for scope and purpose domain items, including specific description of the CPG objectives, health question, and target population, was 78% (range 50-96%). Damiani et al. (35) and Nowicki et al. (42) did not meet the 70% threshold due to gaps in describing their target population. ...

Introduction: Since its approval for adults with moderate-to-severe atopic dermatitis (AD) in 2017, dupilumab has been incorporated into clinical practice guidelines (CPGs). However, recommendations differ internationally, and the quality assessment of their development is unclear. Objective: We aimed to systematically review and appraise the quality of CPGs for adult AD reported since 2017 and map the recommendations for dupilumab initiation relative to conventional systemic therapy (CST). Materials and methods: A literature search was conducted in June 2020 in MEDLINE, EMBASE, SCOPUS, and CINAHL. Twelve CPGs were retrieved. Methodological quality was assessed using the validated Appraisal of Guidelines for Research & Evaluation II tool (AGREE-II). Recommendations were extracted and compared. Results: AGREE-II median scores per domain of the CPGs were (%, r = range): scope/purpose, 78% (50-96); stakeholder involvement, 54% (28-85); rigor of development, 39% (21-63); clarity of presentation, 85% (69-100); applicability, 27% (6-51); and editorial independence, 76% (42-100). Neither met the threshold of 70% quality criteria for rigor of development nor the applicability domains. Three CPGs met the criteria for recommendation without modification. CPGs' approach to dupilumab initiation was as follows: second line, preferred over CST and nbUVB (n = 1/12 CPG); second line, equivalent to CST or nbUVB (n = 3/12 CPGs); third line, after nbUVB or CST (n = 5/12 CPGs); and fourth line after nbUVB and CST (n = 2/12). No consensus was reached for n = 1/12 CPG. Conclusion and relevance: Dupilumab is now incorporated into CPGs for adult AD. These CPGs exhibited good quality in scope/purpose, clarity, and editorial independence domains. However, none met AGREE-II criteria for methodological rigor/applicability. Gaps were found in mechanisms for updates, facilitators/barriers, resource implications, and stakeholder involvement. Only n = 3/12 CPGs met quality criteria for recommendation without modifications. Of these, two favored a conservative sequential approach for the initiation of dupilumab relative to CST, while one did not reach consensus. Our findings highlight divergent recommendations AD treatment, underlining a need to incorporate quality criteria into future guideline development.
... We included 40 CPGs 12-67 of which the majority (27) were from countries with an high sociodemographic index (SDI), 14,[16][17][18][19][20][21][22][23][24][25][26][27][29][30][31][32][33][34][35][36][41][42][43][44][45][46][47][48][51][52][53][54][55][59][60][61][64][65][66][67] with only two 37-40 from a country with a middle-low SDI (both from India) and none from countries with a low SDI. Nine CPGs came from Asia, 13,[36][37][38][39][40][46][47][48][49][59][60][61] one from Australia, 14 (3), Russian (1) and Ukrainian (1). ...

Background Clinical practice guidelines (CPGs) are essential in delivering optimum health care, such as for atopic dermatitis (AD), a highly prevalent skin disease. Although many CPGs are available for AD, their quality has not been critically appraised. Objective To identify CPGs on AD worldwide and assess with validated instruments if those CPGs are clear, unbiased, trustworthy and evidence based (CUTE). Methods We searched MEDLINE, Embase, PubMed, Web of Science, Cochrane Library, Emcare, Epistemonikos, PsycINFO and Academic Search Premier for CPGs on AD published between 1 April 2016 and 1 April 2021. Additionally we hand searched prespecified guideline resources. Screening, data extraction and quality assessment of eligible guidelines were independently carried out by two authors. Instruments used for quality assessment were the Appraisal of Guidelines for Research and Evaluation (AGREE) II Reporting Checklist, the U.S. Institute of Medicine’s (IOM) criteria of trustworthiness and Lenzer’s Red Flags. Results Forty CPGs were included, mostly from countries with a high socio-demographic index. The reported quality varied enormously. Three CPGs scored ‘Excellent’ on all AGREEII-domains: Columbia, the Netherlands and United Kingdom (UK; antimicrobials). Three CPGs scored ‘Poor’ on all domains: Poland (phototherapy), Romania and Serbia. We found no association between AGREEII-scores and a country’s gross domestic product. One CPG fully met all nine IOM criteria (Malaysia) and two fully met eight (European dupilumab and UK antimicrobials). Three CPGs had no red flags: Malaysia, South Korea and UK antimicrobials. ‘Applicability’ and ‘Rigour of development’ were the lowest scoring AGREEII domains; ‘Lack of external review’, ‘Updating procedures’ and ‘Rating strength of recommendations’ met the least IOM criteria; and most red flags were for ‘Limited or no involvement of methodological expertise’ and ‘No external review’. Management of conflict of interests (COI) appeared challenging. When constructs of the instruments overlapped, they showed high concordance, strengthening our conclusions. Conclusions Overall, many CPGs are not clear, unbiased, trustworthy or evidence based (CUTE) enough and lack applicability. Therefore improvement is warranted, for which using the AGREEII instrument is recommended. Some improvements can be easily accomplished through robust reporting. Others, such as transparency, applicability, evidence foundation and managing COI, might require more effort.
... However, severe AD cases require immunosuppressive therapy -and, apart from systemic glucocorticosteroids (administered orally or intravenously in severe skin inflammation flare-ups and erythrodermic exacerbations) the AD patients mainly receive cyclosporin A as well as off-label mycophenolate mofetil, methotrexate or azathioprine. This treatment, however, in some cases, carries the risk of serious side effects, [6] which are certainly due to the drug action's characteristics. In most cases this does not pose a real threat to patients, especially when cyclosporine is taken into consideration. ...
... These percentages are significantly higher than in the 10-year observational studies on AD patients in the Netherlands, where the inefficacy of CsA was at 15%. [6] At the same time they are closer to the results of other, open, randomised studies concerning the optimal CsA dosage in patients with a severe course of AD, where the efficacy of the drug was between 59.8%-51.7% depending on the dosage. ...
... Additionally, 17 articles identified through citation searching were screened, of which 11 did not meet the inclusion criteria and 6 were included. Ultimately, 26 eligible articles were included, consisting of 5 RCTs (Tables S2-S4) (15,16,18,29,30) and 21 guidelines (6)(7)(8)10,19,(43)(44)(45)(46)(47)(48)(49)(50)(51)(52)(53)(54)(55)(56). The main findings are described below. ...

Background: Methotrexate is an off-label therapy for atopic dermatitis. A lack of consensus on dosing regimens poses a risk of underdosing and ineffective treatment or overdosing and increased risk of side effects. This systematic review summarizes the available evidence on dosing regimens. Materials and methods: A literature search was conducted, screening all randomized controlled trials (RCTs) and guidelines published up to 6 July 2023, in the MEDLINE, Embase, and Cochrane Library databases. Results: Five RCTs and 21 guidelines were included. RCTs compared methotrexate with other treatments rather than different methotrexate dosing regimens. The start and maintenance doses in RCTs varied between 7.5–15 mg/week and 14.5–25 mg/week, respectively. Despite varied dosing, all RCTs demonstrated efficacy in improving atopic dermatitis signs and symptoms. Guidelines exhibited substantial heterogeneity but predominantly proposed starting doses of 5–15 mg/week for adults and 10–15 mg/m²/week for children. Maintenance doses suggested were 7.5–25 mg/week for adults and 0.2–0.7 mg/kg/week for children. One guideline suggested a test dose and nearly half advised folic acid supplementation. Conclusion: This systematic review highlights the lack of methotrexate dosing guidelines for atopic dermatitis. It identifies commonly recommended and utilized dosing regimens, serving as a valuable resource for clinicians prescribing methotrexate off-label and providing input for an upcoming consensus study.
... Most of the patients took antihistamines. The use of these drugs is currently not recommended by the Polish Society of Dermatology (PTD) and the European EuroGuiDerm guidelines [31,32]. Nevertheless, the PTD guidelines indicate that some patients may benefit from using antihistamines -especially if other treatments were not effective in controlling pruritus or in case of coexisting AR. ...

Atopic dermatitis (AD) is a chronic, recurrent inflammatory dermatosis. The most characteristic symptoms of the disease include itch, eczematous eruptions and excessive dryness of the skin. Elderly patients with AD represent a poorly characterized population because the physiological ageing, possible comorbidity and polypharmacy modify the clinical presentation typically observed in the younger age groups. The aim of the study is to comprehensively assess the clinical characteristics of elderly patients (>60 years old) with AD. Data were collected from 26 AD patients treated in the Department of Dermatology of the University Hospital in Krakow. Late-onset AD with generalized/prurigo lesions was the most predominant phenotype. Skin biopsy was required in 15 (58%) patients in the differential diagnosis process. Allergic rhinitis, a positive family history of atopy and xerosis were associated with a higher number of hospitalizations during the year prior to the last admission (p = 0.034, p = 0.046 and p = 0.036, respectively). Xerosis was more prevalent among subjects with polypharmacy (p = 0.046) and higher serum total IgE concentration (p = 0.048). AD in elderly patients is a new phenotype of the disease that requires careful differential diagnosis. Aged patients with an individual or family history of atopy, due to the increased incidence of severe exacerbations of AD, may benefit from the introduction of proactive therapy.
... Through a competitive mechanism on H1 receptors, oral antihistamines act by blocking the effects produced by histamine (vasodilation, itching). Most guidelines recognize a possible role of first-generation sedating H1 antihistamines in the treatment, for short periods, of sleep disturbances associated with AD pruritus, due to their sedative effect [134,[166][167][168]. Some authors recognize a rationale in the use of oral antihistamines only in patients with concomitant AD and allergic rhino-conjunctivitis [134,149,169]. ...

Currently, there are a few detailed guidelines on the overall management of children and adolescents with moderate-severe atopic dermatitis. AD is a complex disease presenting with different clinical phenotypes, which require an individualized and multidisciplinary approach. Therefore, appropriate interaction between primary care pediatricians, pediatric allergists, and pediatric dermatologists is crucial to finding the best management strategy. In this manuscript, members of the Italian Society of Pediatric Allergology and Immunology (SIAIP), the Italian Society of Pediatric Dermatology (SIDerP), and the Italian Society of Pediatrics (SIP) with expertise in the management of moderate-severe atopic dermatitis have reviewed the latest scientific evidence in the field. This narrative review aims to define a pathway to appropriately managing children and adolescents with moderate-severe atopic dermatitis.
... Unfortunately, even in this case, the large number of users cannot be completely supported by proper data coming from research. It seems, in fact, that data from clinical trials are still insufficient to allow the use of CAM according to evidence-based medicine principles [29], thereby not being recommended in clinical settings [30]. ...

Background and Objectives: Complementary and alternative medicines (CAMs) are generally considered non-scientific and poor effective therapies. Nevertheless, CAMs are extensively used in common clinical practice in Western countries. We decided to promote a Delphi consensus to intercept the opinion of Italian physicians on CAM use in clinical practice. Materials and Methods: We run a Delphi-based consensus, interviewing anonymously 97 physicians. Of these, only 78 participate to the questionnaire. Results: Consensus about agreement and disagreement have been reached in several topics, including indication, as well as safety issues concerning CAMs. Conclusions: The use of CAMs in clinical practice still lacks evidence. Experts agree about the possibility to safely use CAMs in combination with conventional medicines to treat non-critical medical conditions.

BACKGROUND: Eczema is a chronic and widespread dermatological condition with disabling consequences. A significant percentage of patients who suffer from it resort to alternative therapies, especially homeopathy. This article assesses the relevance of such an approach. METHODS: Narrative literature review, with particular interest for the period from May 2012 to May 2023. We searched in the following databases: PubMed, Science Direct, Scopus, PsycInfo and Cochrane Library. RESULTS: Of the 27 articles listed, only seven address the effectiveness of homeopathy in treating eczema: two prospective observational non-randomized studies, a prospective comparative analysis, an observational longitudinal study, a six-cases series, a double-blind randomized placebo-controlled trial and its replication trial. None indisputably demonstrates a superiority of homeopathy over the placebo effect. More worryingly, side effects to homeopathic treatment are reported, sometimes serious. It also entails a higher cost. CONCLUSIONS: Homeopathy has no place in the medical management of eczema, and its use should be discouraged. Keywords - Eczema, atopic dermatitis, homeopathy, placebo effect, CAM.

Atopic dermatitis (AD) is a chronic inflammatory disease with a heterogeneous pathogenesis correlated with dysregulation of the immune system and a prevalence of the T2-mediated immune pathway. Recent understanding of the pathogenesis of AD has allowed the development of new drugs targeting different mechanisms and cytokines that have changed the treatment approach. The aim of this review is to update knowledge on the standard of care and recent advancements in the control of skin inflammation. In light of recent guidelines, we report on the clinical efficacy of novel treatments, with special attention to situations where biologics and small molecules are involved.

Atopic dermatitis (AD) is a common, chronic, relapsing–remitting inflammatory disease that can be challenging to treat. Patients with mild disease are usually managed well with good skin care practices including moisturization and appropriate bathing along with intermittent use of topical therapies such as topical corticosteroids and/or topical calcineurin inhibitors during flares. Patients with frequent flares may benefit from proactive application of topical therapies twice a week to the most troublesome areas. Patients with severe disease often present significant treatment challenges. Systemic therapies are usually required for severe AD but have varying degrees of success and can be associated with side-effect profiles that require counseling and close monitoring. Phototherapy has been shown to have success in treating moderate-to-severe AD, but several factors can limit its utility and efficacy including cost and access. New therapies are in development targeting specific pathways relevant for AD. Dupilumab was the first biologic treatment approved in North America, Europe, and Japan for adults with moderate-to-severe AD. Although this treatment can lead to rapid improvement in the majority of patients, there are inadequate responders. In this review, we discuss the clinical challenges and treatment options for moderate-to-severe refractory AD.

This guideline was developed as a joint interdisciplinary European project, including physicians from all relevant disciplines as well as patients. It is a consensus‐based guideline, taking available evidence from other guidelines, systematic reviews and published studies into account. This second part of the guideline covers antimicrobial therapy, systemic treatment, allergen‐specific immunotherapy, complementary medicine, psychosomatic counselling and educational interventions, whereas the first part covers methods, patient perspective, general measures and avoidance strategies, basic emollient treatment and bathing, dietary intervention, topical anti‐inflammatory therapy, phototherapy and antipruritic therapy. Management of AE must consider the individual clinical variability of the disease. Systemic immunosuppressive treatment with cyclosporine, methotrexate, azathioprine and mycophenolic acid is established option for severe refractory cases, and widely available. Biologicals targeting the T helper 2 pathway such as dupilumab may be a safe and effective, disease‐modifying alternative when available. Oral drugs such as JAK inhibitors and histamine 4 receptor antagonists are in development. Microbial colonization and superinfection may cause disease exacerbation and can require additional antimicrobial treatment. Allergen‐specific immunotherapy with aeroallergens may be considered in selected cases. Psychosomatic counselling is recommended especially in stress‐induced exacerbations. Therapeutic patient education (‘Eczema school’) is recommended for children and adult patients. General measures, basic emollient treatment, bathing, dietary intervention, topical anti‐inflammatory therapy, phototherapy and antipruritic therapy have been addressed in the first part of the guideline.

Management of AE must consider the individual clinical variability of the disease; highly standardized treatment rules are not recommended. Basic therapy is focused on treatment of disturbed barrier function by hydrating and lubricating topical treatment, besides further avoidance of specific and unspecific provocation factors. Topical anti‐inflammatory treatment based on glucocorticosteroids and calcineurin inhibitors is used for flare management and for proactive therapy for long‐term control. Topical corticosteroids remain the mainstay of therapy, whereas tacrolimus and pimecrolimus are preferred in sensitive skin areas and for long‐term use. Topical phosphodiesterase inhibitors may be a treatment alternative when available. Adjuvant therapy includes UV irradiation, preferably with UVB 311 nm or UVA1. Pruritus is targeted with the majority of the recommended therapies, but some patients may need additional antipruritic therapy. Antimicrobial therapy, systemic anti‐inflammatory treatment, immunotherapy, complementary medicine and educational intervention will be addressed in part II of the guideline.

Atopic dermatitis (AD) is a common inflammatory skin disease that affects both children and adults, including a large number of adults of reproductive age. Several guidelines for the treatment of AD exist, yet specific recommendations for the treatment of pregnant or lactating women and for adults planning to have a child are often lacking. This position paper from the European Task force on Atopic Dermatitis (ETFAD) is based on up‐to‐date scientific literature on treating pregnant and lactating women as wells as adults with AD planning to have a child. It is based on the expert opinions of members of the ETFAD and on existing safety data on the proposed treatments, many of which are derived from patients with other inflammatory diseases or from transplantation medicine. For treating future parents, as well as pregnant and lactating women with AD, the use of topical treatments including moisturizers, topical corticosteroids, tacrolimus, antiseptics such as chlorhexidine, octenidine, potassium permanganate and sodium hypochlorite (bleach) is deemed to be safe. Ultraviolet (UV) therapy may also be used. Systemic treatment should be prescribed only after careful consideration. According to the opinion of the ETFAD, treatment should be restricted to systemic corticosteroids and cyclosporine A, and, in selected cases, azathioprine.

Background Probiotic supplementation in early life may be effective in preventing atopic dermatitis (AD); however, results regarding efficacy have been controversial. Objective The aim of our study was to investigate the effect of probiotic supplementation on the risk of AD. Methods We systematically searched PubMed, EBSCO, Embase and Web of Science databases up to 8 March 2018 for potentially relevant studies regarding probiotic supplementation and AD. Included infants and children were those with probiotic exposure in utero and/or after birth who were not previously diagnosed with AD. We calculated the odds ratios (ORs) and 95% confidence intervals (CIs) and used the Jadad and Newcastle–Ottawa scales to assess methodologic quality. Results A total of 28 studies met the inclusion criteria. Compared with controls, probiotic treatment was associated with a reduced risk of AD (OR 0.69; 95% CI 0.58–0.82, P < 0.0001). The use of probiotics during both the prenatal and the postnatal period significantly reduced the incidence of AD (OR 0.67; 95% CI 0.54–0.82); however, analysis of studies of probiotics given prenatally only or postnatally only did not reach statistical significance. Conclusions Our meta-analysis showed that probiotic supplementation during both the prenatal and the postnatal period reduced the incidence of AD in infants and children. Our findings suggest that starting probiotic treatment during gestation and continuing through the first 6 months of the infant’s life may be of benefit in the prevention of AD.

Atopic dermatitis (AD) is a common cutaneous condition characterized by epidermal barrier disruption, severe skin inflammation, and pruritus. As a result of our growing understanding of disease pathogenesis, the therapeutic armamentarium to manage AD is rapidly expanding. Moving beyond broadly immunosuppressive agents, newer therapies for AD offer more targeted immunomodulation in the forms of phosphodiesterase 4 inhibitors, Janus kinase inhibitors, and anticytokine monoclonal antibodies. While such therapies are generally considered safer than traditional immunosuppressive agents that have been used off label for AD for decades, they are not without risk entirely. In some cases, potential side effects may be difficult to manage. This review summarizes current views on AD pathogenesis and discusses these novel and emerging therapies, including a discussion of the mechanisms of action, potential side effects, and limitations of current clinical trials for each drug. While the rapid and prolific expansion of therapies to treat AD is encouraging, additional studies are needed to adequately evaluate the long-term safety, efficacy, and generalizability among different age groups and disease subtypes.

Introduction: Atopic dermatitis (AD) is the most common cutaneous inflammatory disease in adults and children. In the last few years, the pathogenesis of AD has been profoundly revised and this has led to the identification of novel druggable targets and the development of new agents targeting specific molecular pathways. Despite the high prevalence of atopic dermatitis in the pediatric population, the clinical development of new treatments, either topical or systemic, has been focused on the adult population in recent years; only a limited number of these new agents have been tested in pediatric cohorts. Areas covered: In this review, we describe the pathogenic model of pediatric atopic dermatitis which shows similarities and substantial differences when compared to adult atopic dermatitis. The identification of therapeutic targets is highlighted and novel targeted therapies, both topical and systemic, are discussed. Expert opinion: The current therapeutic armamentarium for pediatric atopic dermatitis is very limited and this represents a critical unmet need. The enhancement of clinical research on pediatric patients is necessary to facilitate an increase in the number of new targeted therapeutic options being available on the market.

Introduction: Many novel medications and herbal medicines have claimed efficacy on atopic dermatitis (AD). Areas covered: This review covers evidence on efficacy of topical and oral forms of novel and investigational drugs. Topical agents include emollients, phosphodiesterase E4 (PDE4) inhibitors, and topical herbs. There is little evidence that ceramides or natural moisturizing factors provide relief in AD. PDE4 inhibitors have shown promise as an effective topical treatment for mild-to-moderate AD with minimal adverse events, and dupilumab as an effective subcutaneous agent for the treatment of moderate-to-severe AD in adult patients with little adverse effects. However, only preliminary data are available for dupilumab in children with AD. The long-term effects of dupilumab are also not known. Potential new systemic treatments include a number of herbal concoctions. Expert opinion: Randomized, double-blind placebo-controlled trials (RCTs) have demonstrated topical PDE4 inhibitors are effective and safe in the treatment of both children and adults with AD but further evaluations are needed. RCTs have also shown that subcutaneous dupilumab is an effective and safe agent for the treatment of AD in adults. Long-term effects of these topical and systemic investigational drugs are currently unavailable. Regarding herbal medications, scientific methods are often flawed and objective evidence is lacking.

Atopic dermatitis (also called AD or eczema) is a chronic skin disease found in up to 1 in 10 adults, causing itchy rashes that may cover most of the body. Ciclosporin, an oral treatment (taken by mouth) commonly used for AD, doesn't always work and can have significant side effects. Other broadly‐acting oral medications are sometimes used, but not approved, for AD. Dupilumab is a new medication approved in many countries for adults with inadequately controlled moderate‐to‐severe AD. Dupilumab specifically targets pathways in the body that drive AD. Researchers in Europe evaluated how well dupilumab injections improved rashes, itch, and daily lives of people whose AD required ciclosporin, but for whom ciclosporin wasn't working or caused intolerable side effects, or whose medical conditions prevented its use. Among 325 participants, 110 received 300 mg dupilumab once‐weekly, 107 received it every two weeks, and 108 received placebo (dummy drug) once‐weekly. All participants used topical (applied to the skin) corticosteroids during the 16‐week study. Dupilumab improved AD rashes: at Week 0, participants’ Eczema Area and Severity Index (EASI) scores were about 31 (scale: 0–72), but by Week 16, 59% to 62% of dupilumab‐treated participants achieved 75% or greater improvement in EASI, versus 29.6% of people on placebo. Dupilumab also improved itch, other symptoms, mood, and quality of life. Conjunctivitis and injection‐site reactions were more frequent among dupilumab‐treated patients; skin infections (excluding herpes) and AD exacerbations (worsening) were more frequent with placebo. The authors conclude that dupilumab plus topical corticosteroids significantly improved AD even in adults with AD who had previously failed treatment with or were unable to use ciclosporin.
