IntroductionVasculitides are a heterogeneous group of diseases characterized by inflammation of the blood vessel walls. Etiological factors include infections, drugs, connective tissue diseases, and malignancies.AimTo examine the demographic characteristics, etiological factors, and treatment options in 75 patients with leukocytoclastic vasculitis.Material and methodsThe study included 75 patients diagnosed with leukocytoclastic vasculitis at our clinic. The patients’ medical records were reviewed to determine their age, sex, presence of systemic symptoms, possible etiological factors, laboratory results, types of cutaneous lesions, locations of the lesions, treatment options, and disease course.ResultsThere were 43 women and 32 men. Cutaneous lesions affected only the lower limbs in 60 of the 75 patients (80%) and usually presented as palpable purpura (64%, n = 48). Arthralgia (26.7%, n = 20) was the most frequent extracutaneous symptom. Of the patients with secondary vasculitis, the most common causes were infections and drugs. The mean age of the patients with Henoch-Schönlein purpura was 26.8 years. There was no significant association between age and renal, gastrointestinal, or joint involvement.ConclusionsThe most common form of vasculitis in our study was cutaneous leukocytoclastic vasculitis. In most of the patients it appeared to be idiopathic. Among drugs, antibiotics were the most common etiological factor. In 4 patients, the cutaneous leukocytoclastic vasculitis behaved like the paraneoplastic syndrome.
Background. Hidradenitis suppurativa (HS) is a chronic, relapsing and debilitating inflammatory disease associated with profound morbidity. Aim. In this multicentre study, we investigated the demographic and clinical features of HS, and determined risk factors of disease severity. Methods. In total, 1221 patients diagnosed with HS from 29 centres were enrolled, and the medical records of each patient were reviewed. Results. The mean age of disease onset was 26.2 AE 10.4 years, and almost 70% (n = 849) of patients were current or former smokers. Mean disease duration was 8.9 AE 8.4 years with a delay in diagnosis of 5.8 AE 3.91 years. Just over a fifth (21%; n = 256) of patients had a family history of HS. The axillary, genital and neck
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
