A survey of bullous diseases in a Turkish university hospital: clinicoepidemiological characteristics and follow-up

Background/aim: Autoimmune bullous diseases, if left untreated, are life-threatening conditions affecting primarily skin and mucous membranes. These blistering disorders are characterized by epidermal or subepidermal detachment. Autoimmunity plays a key role in pathogenesis; therefore, immunosuppressive agents are the treatment of choice. The aim of this study is to document relative frequencies of different autoimmune bullous diseases, patient characteristics, treatment options, and side effects in patients presenting to our bullous skin disease center at Istanbul University, Cerrahpasa, Cerrahpasa Medical Faculty. Materials and methods: Medical files were examined retrospectively for all patients with autoimmune bullous diseases who were followed up between 2003 and 2019 at the Bullous Skin Disease Center at Istanbul University, Cerrahpasa. Results: A total of 346 patient files were examined. Pemphigus vulgaris was the most frequent autoimmune bullous disease, followed by bullous pemphigoid and pemphigus foliaceus, according to our study. There is a general female predominancy for all autoimmune bullous diseases. The most commonly preferred treatment options were high-dose daily corticosteroids. Conclusion: This retrospective study summarizes the patient characteristics, comorbidities, treatment choices, and side effects during 16 years of clinical practice.

Long-term follow-up effect of omalizumab in chronic spontaneous urticaria and its association with serum C-reactive protein levels.

This study aims to determine the efficacy of omalizumab, a humanized monoclonal anti-immunoglobulin E antibody, in patients with chronic spontaneous urticaria (CSU) refractory to conventional therapy, together with the evaluation of serum CRP levels. All the patients with a diagnosis of CSU who were continuously treated with omalizumab (300 mg/mo) for at least 3 months between June 2016 and July 2019 were included in this study. Urticaria activity score (UAS-7) was used for assessment of disease activity. Serum CRP levels were also retrospectively analyzed. When UAS-7 scores before the initiation of therapy were compared to the week 4, 12, 24, and 36 scores after the treatment, each were significantly different from the pretreatment results (P < .01). CRP level prior to treatment was found to be strongly correlated with baseline UAS scores of the patients' (P = .00). At the 12th week of treatment, decline of CRP level was positively and strongly correlated with the decline of UAS (P = .037). In this study, mean UAS decreased, mean rescue medication use declined, and overall therapeutic response improved with omalizumab treatment. Additionally, significant correlation between the decline of CRP levels and treatment response was found.

A Proposal for a New Severity Index for the Evaluation of Chronic Paronychia.

INTRODUCTION: Chronic paronychia (CP) is an inflammatory disease of the nail folds. Staging of CP is important for clinicians. We developed an objective scale that evaluates each finding of CP separately in addition to evaluating the treatment process and follow-up. METHODS: A new "chronic paronychia severity index scale" was developed to enable dermatologists to examine all features of CP. A previous categorical severity scale and this new scale were used for the evaluation of CP by 6 different dermatologists. The dermatologists evaluated the nails with both scales again 20 days later using randomly ordered photographs. RESULTS: Using the previous scale, the intra-observer intraclass correlation coefficient (ICC) values between the first and second evaluations were 0.767, 0.860, 0.734, 0.609, 0.900, and 0.840 for the 6 dermatologists. Using the new proposed scale, the intra-observer ICC values between the first and second evaluations were 0.930, 0.931, 0.942, 0.934, 0.938, and 0.920 for the 6 dermatologists. All intra-observer ICC values were higher for the results of the proposed scale than for those of the previous scale. The inter-observer ICC values were also higher for the proposed scale than for the previous scale for the 6 dermatologists. CONCLUSION: The new scale is a standardized, more suitable, objective, and valuable method to use in clinical practice and studies on CP.
