[Inpatient rehabilitation of adults with atopic dermatitis].

Atopic dermatitis is a chronic inflammatory skin disease which often persists until adulthood. In severe cases, eczematous lesions and pruritus are resistant to therapy and result in depression, impairment of professional activities and social withdrawal. The goal of inpatient rehabilitation measures is to keep the patient involved and active in professional and social activities. Rehabilitative measures include diagnostics and medical therapy according to current guidelines, instruction in basic medical information, psychological intervention (relaxation techniques, improvement of self-confidence), dietetic measures, exercise, and social advice. Patients with atopic dermatitis often have work-related problems which should be identified as early as possible during rehabilitation.

Influence of short-term exposure to airborne Der p 1 and volatile organic compounds on skin barrier function and dermal blood flow in patients with atopic eczema and healthy individuals.

BACKGROUND: Epidemiological studies indicate environmental pollutants to be involved in the increase in the prevalence of allergic diseases. In human exposure studies, volatile organic compounds (VOCs) have been shown to cause exacerbations of allergic asthma whereas, no data concerning atopic eczema (AE) are available. OBJECTIVE: We investigated the effect of airborne VOCs on the skin of patients with AE and controls in the presence or absence of house dust mite allergen, Der p 1. METHODS: In a double-blind crossover study, 12 adults with AE and 12 matched healthy volunteers were exposed on their forearms to Der p 1 and subsequently to a mixture of 22 VOCs (M22, 5 mg/m(3)) in a total body exposure chamber for 4 h. Transepidermal water loss (TEWL) and skin blood flow were measured in all subjects before, during and after exposure. Additionally, an atopy patch test (APT) with Der p 1 was applied to the skin after exposure. RESULTS: A significant increase in transepidermal water loss was observed 48 h after exposure to VOCs as compared with exposure with filtered air in all individuals (mean difference: +34%; 95% Confidence Interval: 7-69%). Prior Der p 1 exposure resulted in a significant rise of dermal blood flow after 48 h in patients with AE but not in controls. Six out of seven patients showed enhanced atopy patch test (APT) reactions to HDM allergen after previous exposure to VOCs. CONCLUSION: Our results show that exposure to VOCs - at concentrations commonly found in indoor environments - can damage the epidermal barrier and enhance the adverse effect of Der p 1 on sensitized subjects with AE. These findings may contribute to a better understanding of the mechanisms underlying the increase in prevalence and exacerbation of AE.

Usefulness of specific immunotherapy in patients with atopic dermatitis and allergic sensitization to house dust mites: a multi-centre, randomized, dose-response study.

BACKGROUND: The effect of specific immunotherapy (SIT) on eczema in atopic dermatitis is not known. Therefore, a multi-centre, randomized dose-response trial, double-blind with respect to the efficacy of a biologically standardized depot house dust mite preparation was performed. METHODS: Eighty-nine adults with a chronic course of atopic dermatitis, SCORAD >or=40 and allergic sensitization to house dust mites [CAP-FEIA >or=3] were included, of whom 51 completed the study. Subcutaneous SIT with a house dust mite preparation (Dermatophagoides pteronyssinus/D. farinae) applying maintenance doses of 20, 2,000 and 20,000 SQ-U in weekly intervals for 1 year. The main outcome measures addressed the change of the SCORAD as average of the values after 9 and 12 months of SIT in comparison with the value at baseline. RESULTS: The SCORAD declined in the three dose groups in a dose-dependent manner (P = 0.0368, Jonckheere-Terpstra test) and was significantly lower in the two high-dose groups (2,000, 20,000 SQ-U) compared with the low-dose group of 20 SQ-U (P = 0.0379, U-test) after 1 year of SIT. The use of topical corticosteroids was significantly reduced with higher doses (P = 0.0007, Mantel-Haenszel chi-square test). CONCLUSIONS: Allergen-SIT for 1 year with a house dust mite preparation is able to improve the eczema in patients with atopic dermatitis who are sensitized to house dust mite allergens and reduces the need for topical corticosteroids. SIT may be valuable in the treatment of this chronic skin disease.

Material odor-odoractive compounds identified in different materials--the surprising similarities with certain foods, possible sources and hypotheses on their formation.

UNLABELLED: Increased efforts have been undertaken by manufacturers to reveal the secrets of material odors, the structure of the odorants responsible, with regard to finding out the source(s) of odor and possible starting points for odor reduction, and therewith product improvement, increased consumer satisfaction and improved indoor air quality. The identification of odor-active compounds in materials by means of gas chromatography-olfactometry (GC-O, also called GC-sniffing), performed at the Fraunhofer Institute for Building Physics (IBP) during the previous years, showed surprising similarities between certain odorants found in materials and those previously identified in certain kinds of food. Examples of important odorants found in different material samples and similarities with food odorants were analyzed. Odorant sources are indicated as regards materials, and possible conditions and mechanisms of formation suggested to show starting points for odor reduction and odor improvement in material development. PRACTICAL IMPLICATIONS: If technical materials are planned to be used indoors and if they spread a distinct odor, the analysis of the compounds contained and emitted by this material using gas chromatography-olfactometry is a means to help reveal the compounds being responsible for that odor. The exact knowledge of the structure of the odorants is the prerequisite for drawing conclusions on possible sources and formation mechanisms and to reveal starting points for odor reduction and product improvement, e.g. by changing ingredients or production conditions. This contributes to an improvement of indoor air quality. Furthermore, quite often the concentrations of certain single odorants found in materials can be very low and the same odorants can be part of other well-known food flavors. This information might be useful to reduce consumers' fears of a possible impairment of their health in the future.

[Facial pigmentation following therapy with terbinafine].

A 65-year-old patient presented with grey-brownish maculae localized on the face. He had been treated with oral terbinafine due to onychomycosis, and the first spots manifested after 4 weeks of therapy. Other drugs were not taken by the patient, who was otherwise in a healthy condition. Histology showed melanin localized within macrophages in the upper and lower dermis. Cutaneous side effects are well described in patients treated with terbinafine and usually present as urticaria or eczema. Severe reactions may occur in rare cases. Hyperpigmentation has not yet been described as a consequence of oral terbinafine. Grey hyperpigmentation as it occurred in our patient has been described as a side effect of therapy with minocycline, amiodarone, tricyclic antidepressants, or heavy metals. This case report shows that drug-induced hyperpigmentation should also be considered if the patient takes drugs not known for this kind of side effect.

Therapy of noninfectious granulomatous skin diseases with fumaric acid esters.

BACKGROUND: Noninfectious granulomatous skin diseases are inflammatory disorders of unknown aetiology which are often recalcitrant to common anti-inflammatory treatment regimens. Recently, in several case reports, fumaric acid esters (FAE) have proved beneficial in granulomatous skin diseases, but studies on a larger collection of consecutive patients have not yet been performed. OBJECTIVES: To investigate the therapeutic efficacy of FAE for the treatment of granulomatous skin diseases. PATIENTS AND METHODS: The therapeutic efficacy and side-effects of FAE were analysed retrospectively in 32 patients with disseminated granuloma annulare (n = 13), annular elastolytic giant cell granuloma (n = 3), sarcoidosis (n = 11), necrobiosis lipoidica (n = 4), or granulomatous cheilitis (n = 1). RESULTS: Three patients discontinued treatment within 4 weeks because of side-effects. Of the remaining 29 patients, 18 patients responded to treatment with FAE. Marked improvement or complete clearance was seen in seven patients. We observed a slight to moderate improvement in 11 patients, and 11 patients did not respond. In patients showing a complete remission, the maximum effect was observed after 8.5 months (SD +/-6 months, range 3-20 months). In two patients with systemic sarcoidosis, the pulmonary changes improved in parallel with the skin. Side-effects were usually mild and resolved spontaneously upon dose reduction or discontinuation of the therapy. CONCLUSIONS: The data presented here indicate that FAE may be considered for the treatment of recalcitrant granulomatous skin disease.

Deficiency in immunoglobulin G2 antibodies against staphylococcal enterotoxin C1 defines a subgroup of patients with atopic dermatitis.

BACKGROUND AND AIM: Atopic dermatitis (AD) is a common chronic inflammatory skin disease often accompanied by cutaneous Staphylococcus aureus colonization and, in this regard, especially complicated by the presence of superantigen-producing strains. Because IgG antibodies comprise an important defence mechanism of the adaptive immune system against bacteria, it was investigated whether AD patients have an abnormal pattern or distribution of superantigen-specific IgG subclass antibodies in association with disease severity and activity. METHODS: Staphylococcal enterotoxin B (SEB) and staphylococcal enterotoxin C1 (SEC1) specific IgG antibody subclasses were assessed in n=89 adult AD patients with mild to severe disease activity as determined by the SCORAD score and in n=28 healthy age-matched controls. Results were correlated with the current status of bacterial skin colonization and severity score. RESULTS: Thirty-eight per cent of the AD patients showed a selective deficiency in IgG2 antibodies against SEC1 compared with only 14% in the control group. The absence of these antibodies was found in both currently colonized and non-colonized AD patients and was associated with a severe phenotype (SCORAD more than 40 points in two-thirds of the deficient patients). However, these patients had normal production levels of IgG2 antibodies against pneumococcal capsular polysaccharide (PCP) and SEB, but higher IgG1 and IgG4 titres against SEC1. Except for elevated total IgG1, total IgG subclass levels were normal in this AD subgroup. Yet, peripheral blood mononuclear cells (PBMCs) derived from these patients clearly produced IL-4 and IL-5 upon SEC1 re-stimulation whereas PBMCs from those providing SEC1-specific IgG2 antibodies failed in the production of these cytokines. CONCLUSION: A subgroup of AD patients suffers from a selective deficiency to produce anti-SEC1 IgG2 antibodies. This patient group is characterized by a severe AD phenotype.

Alpha-toxin is produced by skin colonizing Staphylococcus aureus and induces a T helper type 1 response in atopic dermatitis.

BACKGROUND: Staphylococcus aureus is a well known trigger factor of atopic dermatitis (AD). Besides the superantigens, further exotoxins are produced by S. aureus and may have an influence on the eczema. OBJECTIVE: To explore the impact of staphylococcal alpha-toxin on human T cells, as those represent the majority of skin infiltrating cells in AD. METHODS: Adult patients with AD were screened for cutaneous colonization with alpha-toxin producing S. aureus. As alpha-toxin may induce necrosis, CD4(+) T cells were incubated with sublytic alpha-toxin concentrations. Proliferation and up-regulation of IFN-gamma on the mRNA and the protein level were assessed. The induction of t-bet translocation in CD4(+) T cells was detected with the Electrophoretic Mobility Shift Assay. RESULTS: Thirty-four percent of the patients were colonized with alpha-toxin producing S. aureus and alpha-toxin was detected in lesional skin of these patients by immunohistochemistry. Sublytic alpha-toxin concentrations induced a marked proliferation of isolated CD4(+) T cells. Microarray analysis indicated that alpha-toxin induced particularly high amounts of IFN-gamma transcripts. Up-regulation of IFN-gamma was confirmed both on the mRNA and the protein level. Stimulation of CD4(+) T cells with alpha-toxin resulted in DNA binding of t-bet, known as a key transcription factor involved into primary T helper type 1 (Th1) commitment. CONCLUSION: alpha-toxin is produced by S. aureus isolated from patients with AD. We show here for the first time that sublytic alpha-toxin concentrations activate T cells in the absence of antigen-presenting cells. Our results indicate that alpha-toxin is relevant for the induction of a Th1 like cytokine response. In AD, this facilitates the development of Th1 cell dominated chronic eczema.

Late eczematous reactions to food in children with atopic dermatitis.

BACKGROUND: Food allergy is a common problem in patients with atopic dermatitis (AD), particularly in children. While immediate reactions to food are well characterized, the importance of food as a provocation factor for late eczematous reactions has been a subject of debate for several decades. OBJECTIVE: To investigate the importance of food for the induction of late eczematous reactions in children with AD and to correlate the clinical outcome to the results of specific IgE determinations and atopy patch tests (APTs). METHODS: One hundred and six double-blind placebo-controlled food challenges (DBPCFCs) to cow's milk, hen's egg, wheat and soy in 64 children with AD (median age 2 years) were analysed retrospectively. Total and food-specific IgE were determined by CAP RAST FEIA and APTs with native foodstuff were performed. The diagnostic values of specific IgE and APT results were calculated. RESULTS: Forty-nine (46%) of the challenges were related to a clinical reaction. An exacerbation of AD (late eczematous reaction) commonly occurred 24 h after the ingestion of food. Isolated late eczematous reactions were seen in 12% of all positive challenges. Forty-five percent of the positive challenges were associated with late eczematous responses, which followed immediate-type reactions. The sensitivity of food-specific IgE and the APT was 76% and 70%, respectively. Specific IgE and APT were often false positive, which resulted in low positive predictive values (64% and 45%, respectively). CONCLUSIONS: Late eczematous reactions may often be observed upon food challenge in children with AD. Due to the poor reliability of food-specific IgE and APT results DBPCFCs have still to be regarded as the gold standard for the appropriate diagnosis of food responsive eczema in children with AD.

Birch pollen-related food as a provocation factor of allergic symptoms in children with atopic eczema/dermatitis syndrome.

BACKGROUND: Food allergy to cow's milk or hen's egg is a common problem in children with atopic eczema/dermatitis syndrome (AEDS) but the role of birch pollen-related food for the induction of allergic symptoms is still not clear. PATIENTS/METHODS: Twelve children (median age 5 years) with AEDS underwent an oral challenge with those birch pollen-related foods which were reported to induce no immediate symptoms, but were consumed on a regular basis. Total IgE and specific IgE to birch pollen, Bet v 1/2 and various birch pollen-related foods were determined. RESULTS: Seven of 12 children showed immediate and/or late eczematous reactions upon ingestion of birch pollen-related foodstuff. Four children showed a worsening of eczema 24 h upon oral challenge with a significant difference in SCORAD before and after challenge. There were no differences in terms of total IgE or birch pollen-specific IgE between children with a late eczematous response and non-reacting children. CONCLUSIONS: Birch pollen-related food may induce allergic symptoms in children with AEDS who exhibit a sensitization to birch pollen. Oral challenge tests should be performed in those children who suffer from severe AEDS and who are highly sensitized to birch pollen allergens even in the absence of a history suggestive of food allergy.

The prevalence of positive reactions in the atopy patch test with aeroallergens and food allergens in subjects with atopic eczema: a European multicenter study.

BACKGROUND: The atopy patch test (APT) was proposed to evaluate IgE-mediated sensitizations in patients with atopic eczema (AE). OBJECTIVE: The prevalence and agreement with clinical history and specific IgE (sIgE) of positive APT reactions was investigated in six European countries using a standardized method. METHODS: A total of 314 patients with AE in remission were tested in 12 study centers on clinically uninvolved, non-abraded back skin with 200 index of reactivity (IR)/g of house dust mite Dermatophagoides pteronyssinus, cat dander, grass, and birch pollen allergen extracts with defined major allergen contents in petrolatum. Extracts of egg white, celery and wheat flour with defined protein content were also patch tested. APT values were evaluated at 24, 48, and 72 h according to the European Task Force on Atopic Dermatitis (ETFAD) guidelines. In addition, skin-prick test (SPT) and sIgE and a detailed history on allergen-induced eczema flares were obtained. RESULTS: Previous eczema flares, after contact with specific allergens, were reported in 1% (celery) to 34% (D. pteronyssinus) of patients. The frequency of clear-cut positive APT reactions ranged from 39% with D. pteronyssinus to 9% with celery. All ETFAD intensities occured after 48 and 72 h. Positive SPT (16-57%) and elevated sIgE (19-59%) results were more frequent. Clear-cut positive APT with all SPT and sIgE testing negative was seen in 7% of the patients, whereas a positive APT without SPT or sIgE for the respective allergen was seen in 17% of the patients. APT, SPT and sIgE results showed significant agreement with history for grass pollen and egg white (two-sided Pr > /Z/ < or = 0.01). In addition, SPT and sIgE showed significant agreement with history for the other aeroallergens. With regard to clinical history, the APT had a higher specificity (64-91% depending on the allergen) than SPT (50-85%) or sIgE (52-85%). Positive APT were associated with longer duration of eczema flares and showed regional differences. In 10 non-atopic controls, no positive APT reaction was seen. CONCLUSION: Aeroallergens and food allergens are able to elicit eczematous skin reactions after epicutaneous application. As no gold standard for aeroallergen provocation in AE exists, the relevance of aeroallergens for AE flares may be evaluated by APT in addition to SPT and sIgE. The data may contribute to the international standardization of the APT.

Screening of chemical oxidation processes and other methods for decolorization of urine for its re-use as toilet-flush liquid in ecological sanitation systems.

Because of its potential use as fertilizer, urine ("yellow water") is a resource originating from sanitation. Its separate collection in no-mix toilets is a beneficial aspect of ecological (source control) sanitation. In order to avoid dilution of the fertilizing nutrients with toilet flush water, the utilization of yellow water as toilet flush liquid seems to be advantageous. To be accepted for this purpose, urine has to be decolorized (and also deodorized). In this study activated carbon adsorption, irradiation with UV light of different wavelengths, the advanced oxidation processes ultrasound, UV/H2O2, and photocatalytic oxidation have failed to decolorize urine. Biological treatment caused brown colour of the treated urine. Only ozonation was successful in colour removal, although it did not affect TOC. In spite of darkening of yellow water during biological treatment (generation of humic substances), smaller ozone doses were required for decolorizing the biologically pre-treated urine than for original urine. Photocatalytic oxidation of biologically treated urine also removed brown colour, but the original yellow colour remained. In ozonated urine, yellow colour was reconstituted unless hydrogen peroxide was added. In addition to colour removal, ozone contributed to deodorization as a consequence of ammonia stripping and probably of phenol oxidation.

[Epidemiology of food allergies].

Difficulties resulting from diagnosis of food allergies show an impact on the validity of epidemiological data, which are mainly based on questionnaire data or results from allergy tests for evidence of specific IgE antibodies. The frequency of self-reported adverse food reactions in population based studies ranges between 5% and 33% with women reporting a higher frequency of such reactions. Only two epidemiological studies have performed double blind, placebo-controlled oral food challenge tests. Extrapolating these results, the prevalence of food allergies is estimated at 2% within the general population. An epidemiological questionnaire-based study in France reports on 3.5% of the general population suffering from food allergies. According to studies of the Allergy Ward in Zürich, in 46-60% of all cases skin and mucosa are predominantly affected, with oral allergy syndrome and urticaria being the most frequent manifestations. A food allergy is significantly associated with different manifestations of atopy and predominantly to hay fever, atopic eczema, urticaria and asthma.

[The impact of food allergy in patients with atopic dermatitis].

Besides other trigger factors food allergens have been shown to play a major role in the exacerbation and maintenance of eczematous lesions in patients with atopic dermatitis (AD), particularly in children. Food allergy may not only present as a flare up up of eczema in these patients, but also immediate type reactions and mixed reactions can be observed under food challenge tests. Whereas cow's milk hen's egg, wheat and soy have been identified as important triggers in infants, pollen related foods like nuts, fruit und vegetable have a greater impact in adolescents and adult Food specific T cells have been identified as effector cells in food responsible eczema and food specific T cell clones could be generated from lesional skin of patients who reacted with a worsening of their AD upon oral challenge tests. Due to the poor reliability of in-vitro (RAST) and skin tests (skin prick test (SPT), atopy patch test (APT)) the double blind placebo controlled food challenge (DBPCFC) is regarded as the gold standard in the diagnostic work-up of food allergy. Once a food allergy has been diagnosed, a specific elimination diet represents the first line therapy, which has to consider the supplementation of essential nutrients.

[Systemic therapy of atopic dermatitis].

The optimal treatment of atopic dermatitis requires regular medical supervision. The course of this chronic skin disease is influenced by multiple triggers which are relevant for the treatment. The mainstays of topical therapy include regular use of emollients coupled with antimicrobial substances, corticosteroids and immune modulators as required. Ultraviolet radiation and immunosuppressive regimens represent further options for the treatment of severe exacerbations and may lead to long term improvement. Data from experimental studies provide insight into possible future treatment methods.

Staphylococcus aureus: colonizing features and influence of an antibacterial treatment in adults with atopic dermatitis.

BACKGROUND: The skin of up to 100% of patients with atopic dermatitis (AD) is colonized with Staphylococcus aureus. Of all S. aureus strains isolated from lesional skin, up to 65% have been shown to produce exotoxins with superantigenic properties. Patients colonized with S. aureus have been treated with antibiotics in several open and double-blind placebo-controlled studies, with conflicting results. These studies did not consider the anterior nares as a reservoir of S. aureus, or the possibility of transmission between patients and their contacts. Moreover, adult patients have not so far been investigated. OBJECTIVES: To investigate the colonizing features of S. aureus in adults with AD and in their contacts, and the effect of an antimicrobial treatment of the patients and their partners. METHODS: Swabs were taken from the skin and anterior nares of 66 adults with AD. S. aureus strains were screened for the production of exotoxins in 32 patients. Ten patients (two with toxigenic strains, eight with non-toxigenic strains) were treated orally with cefalexin, chlorhexidine ointment was applied to the skin, and the anterior nares were treated with mupirocin ointment. A bath containing potassium permanganate was taken daily. In addition, their partners were treated topically. RESULTS: Sixty-two of 66 patients (94%) were carriers of S. aureus, and mostly harboured the bacteria on both skin and anterior nares. Ten of 32 (31%) patients were colonized with toxigenic strains. The Severity Scoring in AD (SCORAD) score decreased in nine of 10 patients who received antimicrobial treatment (P < 0.001), and this effect was more pronounced in patients with a baseline SCORAD > 50. CONCLUSIONS: S. aureus may play an important role as an aggravating factor in adults with AD, as antimicrobial treatment leads to a significant improvement of AD in patients who are colonized with the bacterium.

Hodgkin's disease in the elderly: current status and future directions.

In general, it was agreed that high rates of toxicities during treatment occur in the elderly and that there is a frequent occurrence of early relapse. It is clear that different combinations of effective therapies with lower toxicity are required. It was felt, however, that certainly in the 60-70 year age group, approaches should be vigorous to and the same diagnostic and staging procedures as in younger individuals, but with much closer monitoring of toxicity and response to treatment. It was felt that as part of the approach, liberal support with haemopoeitic growth factors (G-CSF) was necessary to reduce prolonged neutropenia. It is important to understand that age in general is not a contrary indication for aggressive treatment and that biologically younger patients under the age of 65 years, in good physical and mental condition, often should be given with stage-adapted treatment, analogous to conventional treatment protocols for the <60 years age group. It was also considered that, in patients who clearly could not accept conventional treatment, study groups could begin to define the best palliative care for patients with pre-existing organ impairment, and that in all situations of assessment, whether in trial or not, there should be a detailed prospective assessment of quality of life parameters.

A randomized monocentric trial in febrile neutropenic patients: ceftriaxone and gentamicin vs cefepime and gentamicin.

A prospective, randomized, controlled monocentric trial was performed to evaluate the efficacy and safety of once daily ceftriaxone 2 g plus gentamicin 5 mg/kg in comparison to cefepime 2 g t.i.d. plus gentamicin 5 mg/kg q.d. in the treatment of neutropenic fever. In case of fever (oral temperature > or =38.5 degrees C on one occasion or > or =38.0 degrees C twice within 24 h) and a granulocytopenia (neutrophil count below 500 or below 1000/microl when expected to fall below 500 within 72 h), patients with hematological malignancies or solid tumors were assigned to ceftriaxone or cefepime, each with gentamicin. The primary endpoint was defined as defervescence on day 4-6 followed by at least 7 afebrile days. Secondary endpoints were overall response, defined as defervescence on day 28 and toxicity. Two hundred eleven episodes were included. Fever of unknown origin (FUO) accounted for 124 episodes (58.8%), microbiologically defined infection (MDI) for 39 (18.5%), clinically defined infection (CDI) for 25 (11.8%), and both clinically and microbiologically defined infection (CMDI) for 19 episodes (9%). On an intent-to-treat basis 207 episodes were evaluable for the primary endpoint. Ceftriaxone plus gentamicin and cefepime plus gentamicin were successful in 49.5% and 51%, respectively. Overall response was achieved on study day 28 in 92.5% and 91%, respectively. Diarrhea was more frequent with ceftriaxone/gentamicin (6.5% vs 17%), while nausea/vomiting was less (12.1% vs 5%). Once-daily ceftriaxone plus gentamicin was not inferior to cefepime t.i.d. plus gentamicin q.d. in the empirical treatment of neutropenic fever.
