Baseline characteristics, disease severity and treatment history of patients with atopic dermatitis included in the German AD Registry TREATgermany.

BACKGROUND: The Atopic Dermatitis (AD) TREATgermany registry was initiated by the German Society for Dermatology (DDG) in 2011 to evaluate the 'real-life' situation of health care for patients with AD. OBJECTIVES: Interim data analysis on baseline characteristics as well as current and prescribed systemic treatments of the TREATgermany registry patients. METHODS: Patients (≥18 years) with moderate-to-severe AD [objective (o)SCORAD > 20], or with current or previous anti-inflammatory systemic treatment for AD within 24 months, were included and are followed up over at least 24 months. To assess clinical signs, the eczema area severity index (EASI, 0-72), the oSCORAD (0-83) and the Investigator Global Assessment (IGA; 6-point scale) were used. The disease severity was globally scored by the patients [Patient Global Assessment (PGA); six-step Likert scale]. Disease symptoms were assessed by the patient-oriented eczema measure (POEM, 0-28) and numeric rating scales (NRS, 0-10). Health-related quality of life was measured using the dermatological life quality index (DLQI, 0-30). RESULTS: A total of 612 patients were recruited across 32 sites between 06/2016 and 01/2019 (mean age: 42.6 ± 14.2 years; mean oSCORAD: 40.8 ± 16.3). The mean POEM score was 16.3 ± 7.5. Pruritus was rated highest among subjective symptoms (NRS: 5.4 ± 2.7). The mean DLQI value was 11.3 ± 7.5. The frequency of arterial hypertension was lower (20.8%) compared with the general population, whilst this was higher for depression (10%). More than 60% of the patients had received systemic glucocorticosteroids, and 36.8% had received cyclosporine A prior to inclusion. Dupilumab was the leading substance documented as either 'current' (12.1%) or 'prescribed' (31.4%) at baseline. CONCLUSIONS: These 'real-life' data clearly demonstrate the substantial disease burden. Most of TREATgermany patients were already treated with or prescribed dupilumab at baseline. Moreover, current findings indicate the urgent need for further alternative agents in order to achieve a perceptible improvement of quality of life of patients with moderate-to-severe AD.

[Decreased professional performance and quality of life in patients with moderate-to-severe atopic eczema : Results from the German atopic eczema registry TREATgermany]. / Verminderte berufliche Leistungsfähigkeit und Lebensqualität bei Patienten mit moderater bis schwerer Neurodermitis : Ergebnisse aus dem Deutschen Neurodermitisregister TREATgermany.

BACKGROUND: Clinical registries may provide high-quality evidence on the use and effectiveness of therapeutic interventions under real-life conditions. Adults with moderate-to-severe atopic eczema (atopic dermatitis [AD]) are enrolled into TREATgermany and prospectively followed over at least 2 years. This paper analyses the association between dermatological quality of life and work limitations. MATERIALS AND METHODS: Treatment modalities and a broad set of physician- and patient-reported outcome measures are documented using validated instruments to assess clinical disease severity (EASI [Eczema Area and Severity Index], objective SCORAD [objective-SCORing Atopic Dermatitis]), quality of life (DLQI [Dermatology Life Quality Index]), symptoms (POEM [Patient-oriented Eczema Measure]), global disease severity, as well as patient satisfaction and work limitations including presenteeism (WLQ [Work Limitation Questionnaire]). From 06/2016 until 12/2017, 241 individuals (mean age 43 ± 15 years, 38.6% female) were enrolled at 19 recruitment centers; 69% of the patients were employed. RESULTS: Employed persons had DLQI and WLQ scores of 10.6 ± 6.9 points and 17.7 ± 18.1%, respectively. Mean presenteeism was substantial accounting for 9.2%. With coefficients of 0.39 and 0.33 WLQ and presenteeism scores significantly correlate with DLQI (p < 0.000). Bootstrapped regression models showed that the limitations in coping with work requirements increase by 1.7% as DLQI increases by one point. Lower quality of life due to AD is most strongly associated with limitations in the area of physical and performance requirements in general. Presenteeism increases by 0.5% as DLQI increases by one point. CONCLUSION: Moderate-to-severe AD has substantial adverse economic impact with mean productivity loss of patients of almost 10%. Future analyses from TREATgermany will address the impact of innovative treatment modalities on quality of life and work productivity of patients with moderate-to-severe AD.

Guideline: vulvovaginal candidosis (AWMF 015/072), S2k (excluding chronic mucocutaneous candidosis).

The oestrogenised vagina is colonised by Candida species in at least 20% of women; in late pregnancy and in immunosuppressed patients, this increases to at least 30%. In most cases, Candida albicans is involved. Host factors, particularly local defence mechanisms, gene polymorphisms, allergies, serum glucose levels, antibiotics, psycho-social stress and oestrogens influence the risk of candidal vulvovaginitis. Non-albicans species, particularly Candida glabrata, and in rare cases also Saccharomyces cerevisiae, cause less than 10% of all cases of vulvovaginitis with some regional variation; these are generally associated with milder signs and symptoms than normally seen with a C. albicans-associated vaginitis. Typical symptoms include premenstrual itching, burning, redness and odourless discharge. Although itching and redness of the introitus and vagina are typical symptoms, only 35-40% of women reporting genital itching in fact suffer from vulvovaginal candidosis. Medical history, clinical examination and microscopic examination of vaginal content using 400× optical magnification, or preferably phase contrast microscopy, are essential for diagnosis. In clinically and microscopically unclear cases and in chronically recurring cases, a fungal culture for pathogen determination should be performed. In the event of non-C. albicans species, the minimum inhibitory concentration (MIC) should also be determined. Chronic mucocutaneous candidosis, a rarer disorder which can occur in both sexes, has other causes and requires different diagnostic and treatment measures. Treatment with all antimycotic agents on the market (polyenes such as nystatin; imidazoles such as clotrimazole; and many others including ciclopirox olamine) is easy to administer in acute cases and is successful in more than 80% of cases. All vaginal preparations of polyenes, imidazoles and ciclopirox olamine and oral triazoles (fluconazole, itraconazole) are equally effective (Table ); however, oral triazoles should not be administered during pregnancy according to the manufacturers. C. glabrata is not sufficiently sensitive to the usual dosages of antimycotic agents approved for gynaecological use. In other countries, vaginal suppositories of boric acid (600 mg, 1-2 times daily for 14 days) or flucytosine are recommended. Boric acid treatment is not allowed in Germany and flucytosine is not available. Eight hundred-milligram oral fluconazole per day for 2-3 weeks is therefore recommended in Germany. Due to the clinical persistence of C. glabrata despite treatment with high-dose fluconazole, oral posaconazole and, more recently, echinocandins such as micafungin are under discussion; echinocandins are very expensive, are not approved for this indication and are not supported by clinical evidence of their efficacy. In cases of vulvovaginal candidosis, resistance to C. albicans does not play a significant role in the use of polyenes or azoles. Candida krusei is resistant to the triazoles, fluconazole and itraconazole. For this reason, local imidazole, ciclopirox olamine or nystatin should be used. There are no studies to support this recommendation, however. Side effects, toxicity, embryotoxicity and allergies are not clinically significant. Vaginal treatment with clotrimazole in the first trimester of a pregnancy reduces the rate of premature births. Although it is not necessary to treat a vaginal colonisation of Candida in healthy women, vaginal administration of antimycotics is often recommended in the third trimester of pregnancy in Germany to reduce the rate of oral thrush and napkin dermatitis in healthy full-term newborns. Chronic recurrent vulvovaginal candidosis continues to be treated in intervals using suppressive therapy as long as immunological treatments are not available. The relapse rate associated with weekly or monthly oral fluconazole treatment over 6 months is approximately 50% after the conclusion of suppressive therapy according to current studies. Good results have been achieved with a fluconazole regimen using an initial 200 mg fluconazole per day on 3 days in the first week and a dosage-reduced maintenance therapy with 200 mg once a month for 1 year when the patient is free of symptoms and fungal infection (Table ). Future studies should include Candida autovaccination, antibodies to Candida virulence factors and other immunological experiments. Probiotics with appropriate lactobacillus strains should also be examined in future studies on the basis of encouraging initial results. Because of the high rate of false indications, OTC treatment (self-treatment by the patient) should be discouraged.

[Phlebology in German departments of dermatology. An analysis on behalf of the German Society of Phlebology]. / Phlebologie an deutschen Hautkliniken. Eine Bestandsaufnahme im Auftrag der Deutschen Gesellschaft für Phlebologie.

BACKGROUND: Phlebologic diseases have become extremely common and have major socio-economic impact. However, the percentage of dermatologists working in phlebology appears to be decreasing according to the data of the German Society of Phlebology (DGP). METHODS: To investigate the reasons for this development, we--on behalf of the DGP--sent a questionnaire to 120 German Departments of Dermatology in autumn 2012. RESULTS: In 76 returned questionnaires, the number of physicians with additional fellowship training in phlebology averaged 1.5; the average number of those who fulfill the criteria for training fellows in phlebology was 0.9. In 71.1 % of the departments there was a phlebologist. A special phlebologic outpatient clinic existed in 73.7 % of the departments. Sonography with Doppler (89.5 %) and duplex (86.8 %) was used as the most frequent diagnostic tool. For therapy, compression (94.7 %), sclerotherapy (liquid 78.9 %, foam 63.2 %, catheter 18.4 %), endoluminal thermic procedures (radio wave 28.9 %, laser 17.1 %) and surgery (especially crossectomy and stripping 67.1 %, phlebectomy of tributaries 75 %) were used. The average number of treatments was very heterogenous in the different departments. CONCLUSIONS: Phlebology definitely plays an important role in dermatology. Most departments fulfill the formal criteria for the license to conduct advanced training in phlebology. A wide spectrum of phlebological diagnostic and therapeutic procedures is available.

CHILD syndrome in a boy.

CHILD syndrome (congenital hemidysplasia with ichthyosiform nevus and limb defects) occurs, as a rule, exclusively in girls because the underlying X-linked gene exerts a lethal effect on male embryos. In this report the characteristic manifestations of CHILD syndrome are described in a 2-year-old boy with a normal chromosome constitution 46,XY. This exceptional case is best explained by the assumption of an early somatic mutation and thus compatible with the concept of X-linked dominant male-lethal inheritance of this trait.

Skin susceptibility to dithranol: contact allergy or irritation?

A pronounced skin reaction to rather low concentrations of dithranol is often observed. The question arises as to whether this represents an allergic or irritant reaction. We performed patch tests with dithranol ointment in various concentrations on psoriatic patients and healthy volunteers. The results failed to show any clear-cut difference in skin reactions between psoriatic patients and healthy volunteers. One subject with a previously known skin hyperreactivity to dithranol showed a similar response to those of some healthy probands. However, subjects showing a pronounced response to rather low concentrations of dithranol also demonstrated a strong reaction to sodium lauryl sulphate, a standard irritant. We conclude that increased reactivity to dithranol most likely reflects an increased genuine skin susceptibility, rather than an allergic response.

Filamentous fungi and yeasts on mattresses covered with different encasings.

Besides mites, filamentous fungi and yeasts play an important role as domestic allergens. Among different allergen avoidance strategies the efficacy of synthetic mattress encasings has been demonstrated for the reduction of house dust mites. Whether these synthetic encasings are also able to reduce the growth of fungi on the mattress under domestic conditions has not been assessed so far. To determine if the fungal growth on mattresses can be reduced by the use of synthetic encasings we assessed the fungal colonisation of mattresses covered either by conventional cotton encasings or by polyurethane encasings impermeable to particles > 3 mum. Within a 12-month period dust samples were obtained from the mattresses. Fungal quantities were measured by counting colonies on agar plates incubated at 20 degrees C and 37 degrees C. The counts of fungi were significantly higher on mattresses with cotton encasings. Penicillium spp. and Aspergillus spp. were isolated most frequently. Therefore the application of synthetic encasings with similar properties to the encasings used in this investigation is recommended as part of an allergen avoidance strategy for patients sensitised to fungal allergens.

Evaluation of skin susceptibility to irritancy by routine patch testing with sodium lauryl sulfate.

Irritant patch testing with sodium lauryl sulfate (SLS) will become more and more a routine test determining skin susceptibility in men. Recently, it has been shown that for practical reasons, irritant SLS patch testing can take place on the back simultaneously with a routine allergic patch test to other contact allergens. However, SLS patch testing has mostly been performed on the forearm in studying experimental skin irritation so far. The aim of this study was to determine whether there is a relationship in skin response to aqueous SLS (0.125%; 0.25%; 0.5% and 1.0%) between the forearm and the back assessed by visual scoring and measurement of transepidermal water loss (TEWL). We found a pronounced reaction of the forearm compared to the back. TEWL values as well as visual scores correlated well with SLS concentration. There was also a high correlation in visual scoring between the forearm and the back. Based on test sensitivity and specificity we suggest a 48 hrs patch test for routine screening with 0.5% SLS on the forearm evaluated by TEWL measurement or visual scoring 24 hrs after patch removal. A mild erythema (scored as < or =1) is considered to be normal. If for practical reasons, the SLS patch is placed on the back simultaneously with the allergic patch test, 0.5% SLS may be sufficient, too. TEWL measurement so far provides a reliable method and will certainly be necessary for experimental studies on irritant skin reactions, particularly when different SLS concentrations are used. After a 48 hrs patch test with SLS 0.5% TEWL measurement should be performed at 72 hrs. A value of < or =31.6 g/m(2)hr seems to follow the normal distribution.

Epidemiology and clinical classification of onychomycosis.

OBJECTIVES: To review recent data - what is new in the epidemiology of onychomycoses? To identify the most relevant diagnostic criteria for effective therapy. METHODS: The preliminary results of the European Onychomycosis Observatory (EUROO) study were analysed. In this international study, physicians completed questionnaires concerning patient profile and the disease. RESULTS: One of the most interesting novel findings was that sampling requests were often not made [only 3.4% of general physicians (GPs) and 39.6% of dermatologists]. This means that no information about causative agent(s) was available, hindering appropriate treatment choice. Furthermore, contrary to previous findings, 70.7% of participants did not practice sports. Lastly, these preliminary findings showed that treatment strategy depends largely on the type of treating physician, with GPs preferring monotherapy and dermatologists preferring combination therapy. CONCLUSIONS: A consensus was reached that treatment strategy should depend on the severity of nail involvement and the causative fungus. It is thus important to promote the importance of sampling. To simplify the choice of an appropriate treatment, onychomycosis may be divided into just two clinical groups: onychomycosis with and without nail matrix area involvement. However, the distinct clinical findings (number and type of affected nails, multimorbidity, drug interaction, etc.) in each individual case must be taken into account to ensure an appropriate treatment decision.
