Autoantibody Profile of a Cohort of 54 Italian Patients with Linear IgA Bullous Dermatosis: LAD-1 Denoted as a Major Auto-antigen of the Lamina Lucida Subtype.

Linear IgA bullous dermatosis (LABD) is characterized by presence of multiple IgA autoantibodies, and a comparatively lesser number of IgG antibodies, directed against different hemidesmosomal antigens. The main autoantigens are LAD-1, LABD-97, BP180 and BP230, type VII collagen and laminin 332. We retrospectively studied the serology of 54 Italian patients with LABD using enzyme-linked immunosorbent assay (ELISA), immunoblotting assay, and indirect immunofluorescence on monkey oesophagus and salt-split skin. Among these, indirect immunofluorescence of salt-split skin elicits the greatest sensitivity. Sixty-three percent of the sera were observed to be positive, with a lamina lucida pattern observed in 48%, a sub-lamina densa pattern in 2% and a mixed pattern in 13% of the cases. IgA reactivity to LAD-1 on immunoblotting was found in 52% of sera, to BP180-NC16A by ELISA in 32% and to BP230 in 26%. Only 17% of patients possessed circulating IgG autoantibodies. LAD-1 was determined to be a major autoantigen of the lamina lucida subtype. Combined serological assays demonstrated a high sensitivity (82%), suggesting that this approach could support diagnosis when a biopsy is not feasible or direct immunofluorescence results are negative.

Neuro sweet syndrome: a systematic review. A rare complication of Sweet syndrome.

Sweet's syndrome (SS) is an inflammatory disease characterized by fever, leucocytosis and distinctive skin lesions that histologically consist of a dermal infiltrate of neutrophils with nuclear fragmentation. Aseptic neutrophilic inflammation may occur also in other organs. Central nervous system involvement in SS, Neuro-Sweet's syndrome (NSS), is rare and reported especially among Asian patients. A systematic review of the literature has been performed to find articles reporting cases of SS with neurological involvement. The search terms: "Sweet's syndrome/disease with neurological involvement, Neuro Sweet Syndrome/Disease" were used in the Pubmed Database. Sixty-nine NSS patients including 46 males and 23 females, more Asian than Caucasian, have been described from 1983 to date. The average age was 48.7 year-old. The most representative neurologic symptom was the altered state of consciousness, followed by headache and memory disorders. Differently from SS with skin or other district involvement, NSS appears to be more common in Asian patients than in Caucasian ones and affects mainly the male sex in the third or fourth decade of life. A very wide range of symptoms and signs can occur, depending on which part of the nervous system is affected. Initial presentation is usually with the SS typical skin lesions followed by neurological involvement. However, also an opposite presentation or a simultaneous skin and nervous involvement may happen. Awareness of the possible neurological complications in SS is important to avoid unnecessary therapies for other forms of meningoencephalitis and lead to successful treatment with systemic corticosteroids.

The high incidence of anti-Ro/SSA and anti-p200 antibodies in female patients with connective tissue diseases confirms the importance of screening for congenital heart block-associated autoantibodies during pregnancy.

It is known that anti-Ro/SSA positivity leads to higher risk of miscarriage and fetal cardiac malformations. Particularly, anti-p200 antibodies against a finer specificity of the Ro/SSA antigen, have been associated with congenital heart block. The aim of the study was to assess the frequency of anti-p200 among female patients with different connective tissue diseases and, among these, the relevance of anti-p200 values in patients with cutaneous diseases compared to systemic diseases. Anti-p200 were investigated in 110 anti-Ro/SSA positive female sera, sent to our laboratory between 2008 and 2014 with suspect of connective disease, by using ELISA testing. Positivity was found in 40.9 % samples, 34 of them showed a strong positivity (values ≥ 1.0, cut off = 0.7). Patients with systemic diseases were anti-p200 positive in the 45.9 % of cases while patients with cutaneous diseases were positive in the 24.0 % of cases. Positivity for anti-p200 antibodies was revealed in 24.0 % of patients with discoid lupus erythematosus; 100 % of patients with dermatomyositis; 40.0 % of patients with mixed connective tissue disease; 25.0 % of patients with rheumatoid arthritis; 100 % of patients with Sjögren's syndrome; 33.3 % of patients with subacute cutaneous lupus erythematosus; 42.9 % of patients with systemic lupus erythematosus; 80.0 % of patients with systemic sclerosis. No significant difference in anti-p200 prevalence was found between systemic and cutaneous involvement, nevertheless, considering only positive sera, the antibody titer was higher in systemic diseases rather than in cutaneous diseases (2.6 ± 1.7 and 1.7 ± 1.9; p = 0.041). The authors think screenings for anti-Ro/SSA and anti-p200 antibodies should be included in the laboratory checklist for pregnancy.

Epidemiological study of onychomycosis in older adults with onychodystrophy.

AIM: To identify the prevalence of onychomycosis and epidemiological features in older adults (>65%) with toenail onychodystrophy. In particular, the aim of the study was to analyze risk factors/protective factors, clinical manifestations, comorbidities and etiological agents. METHODS: A prospective study was carried out from February 2012 to May 2012 at San Martino-IST of Genoa, Italy. The inclusion criteria for enrolment were the presence of onychodystrophy of one or more toenails and age >65 years. The exclusion criteria were systemic/topical antifungal treatments in the previous 6 months, drilling of the nail plate in the previous 6 months and a specialist's diagnosis or suspicion of onychomycosis. A database was created for the patients' anamnesis, the clinics and testing results. Several statistical analyses were carried out. RESULTS: A total of 100 patients fulfilled the inclusion criteria. A total of 35 cases had positive results, and the etiological agent was isolable in 14 cases. The most represented was Trichophyton mentagrophytes followed by Trichophyton rubrum and others. Multivariate logistic regression analysis showed the significant roles of sex and diabetes as risk factors, and the use of statins as a protective factor. CONCLUSIONS: Onychomycosis has a high prevalence in older adults with onychodystrophy. It is important not to overlook onychodystrophy, and to carry out laboratory testing to exclude a fungal infection. In fact, as older patients often cannot undergo systemic antifungal therapies, it is fundamental to treat them early and avoid the spread of infection.

A retrospective study of cutaneous drug reactions in an outpatient population.

BACKGROUND: Adverse cutaneous drug reactions (ACDR) are unexpected cutaneous changes occurring at drug dosages that are normally used for disease prophylaxis, diagnosis or treatment. OBJECTIVE: The aim of the study was to determine the clinical types of ACDR, the causative agents, the latency time between drug intake and onset of ACDR and the recovery time in an outpatient population. METHOD: Ninety-five patients diagnosed with ACDR at the Department of Dermatology of the University of Genoa between 2003 and 2012 were retrospectively studied. RESULTS: Antimicrobials, especially cephalosporins, were the most responsible for ACDR, followed by non-steroidal anti-inflammatory drugs and antihypertensives. The most common clinical manifestations were exanthema (42.1%), erythema multiforme (10.53%) and vasculitis (9.53%). Patients with peripheral eosinophilia showed a more severe clinical manifestation, they were treated with systemic therapies and their recovery time was longer. CONCLUSION: It is important to have an appropriate clinical approach according to the ACDR severity degree. We think that eosinophilia may characterise severe cutaneous eruptions and that it should always be investigated when ACDR is suspected in order to manage the patient with the appropriate treatment.

Efficacy of treatment with oral alitretinoin in patient suffering from lichen simplex chronicus and severe atopic dermatitis of hands.

Lichen simplex chronicus (LSC) is a skin disorder characterized by chronic itching and scratching, which can lead to thick, leathery, brownish skin, sometimes with papules and can be associated with atopic eczema. We report the case of a 52-year-old man with a 45-year atopic condition and presenting LSC in his dorsum. After a 3-month treatment with alitretinoin at the daily dosage of 30 mg, we have observed a moderate improvement of the hand eczema together with a substantial clinical improvement of LSC and an almost complete resolution of pruritus. We want to report this peculiar case to suggest the use of oral alitretinoin for LSC.

Fissured tongue responding to biologics during the treatment of psoriasis: the importance of detecting oral involvement of psoriasis.

Recent studies have provided more evidence that psoriasis can give mucosal lesions, especially oral. Nonspecific lesions such as fissured tongue and geographic tongue are relatively frequent in patients suffering from psoriasis. We report a case of a patient presenting an important improvement of his fissured tongue paralleling the improvement of the cutaneous lesions after a 5-month systemic therapy with infliximab. The authors think it would be important to consider possible oral lesions in patients suffering from psoriasis in normal practice and to evaluate them introducing specific clinical scales.
