Serum cytokines in ANCA-associated vasculitis: Correlation with disease-related clinical and laboratory findings.

Background: Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis is a systemic, autoimmune disease. Cytokine dysregulation during active disease and clinical remission, reflects significant immunological activity in various disease stages, and might be responsible for the potential relapse of ANCA-vasculitis.

Objectives: This study aimed to screen serological profiles in active granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA), and to determine their associations with clinical characteristics.

Review of practical recommendations for otolaryngologists and head and neck surgeons during the COVID-19 pandemic.

Introduction: Otolaryngologists are at very high risk of COVID-19 infection while performing examination or surgery. Strict guidelines for these specialists have not already been provided, while currently available recommendations could presumably change in course of COVID-19 pandemic as the new data increases.

Objectives: This study aimed to synthesize evidence concerning otolaryngology during COVID-19 pandemic.

Otorhinolaryngological dysfunctions induced by chronic kidney disease in pre- and post-transplant stages.

Purpose: Otorhinolaryngological abnormalities are common complications of chronic kidney disease (CKD) and its treatment. The main aim of this study was to provide a brief and precise review of the current knowledge regarding CKD and its treatment-related influence on head and neck organs.

Methods: The Medline and Web of Science databases were searched using the terms "chronic kidney disease", "kidney transplantation", "immunosuppression", "dialysis" in conjunction with "otorhinolaryngological manifestation".

Serum levels of interleukin-32 and interleukin-6 in granulomatosis with polyangiitis and microscopic polyangiitis: association with clinical and biochemical findings.

Background: Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis is an autoimmune disorder of unknown etiology with dysregulated cytokines levels.

Objectives: The main aim of this study was to assess the clinical correlation between antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis, granulomatosis with polyangiitis (GPA) serum levels of the microscopic polyangiitis (MPA), serum levels of the proinflammatory cytokines, interleukin (IL)-32 and interleukin-6.

Methods: Study included 71 patients, 47 with GPA and 24 with MPA.
