Compared to healthy controls, mean platelet volume (MPV) is frequently higher in patients with Familial Mediterranean fever (FMF) but lower in AA amyloidosis patients. The reason for the difference in MPV levels in FMF patients with and without AA amyloidosis is unclear. The aim of the study was to determine whether low MPV is unique to AA amyloidosis or MPV is similarly low in all glomerular diseases as a result of proteinuria and/or renal dysfunction. ⋯ This study is the largest study of MPV in patients with biopsy proven AA amyloidosis and confirms previous studies reporting low MPV in AA amyloidosis. This study indicates that low MPV in AA amyloidosis cannot be explained with proteinuria and renal dysfunction.

Determining the characteristics and risk factors of severe disease is extremely important to combat atopic dermatitis (AD), which has recently shown increasing prevalence. In this study, we aimed to investigate the clinical characteristics of pediatric patients with AD and identifying the factors associated with the severity of the disease. ⋯ Our findings show that early-onset, food sensitivity, living in rural areas, having familial atopy history and passive cigarette smoke exposure play a role in severe AD. Since it is remarkably correlated with SCORAD scores, eosinophil count can be used as a marker to assess the severity of AD in children.

Common variable immunodeficiency (CVID) characterized by defective immunoglobulin production is the most prevalent form of symptomatic primary immunodeficiency (PID) in adults. We aimed to reveal the clinical features of adults with CVID and to evaluate the effects of immunoglobulin replacement treatment (IRT) on hemato-immunological findings. ⋯ There are apparent relationships among chronic diarrhoea and low body weight, and deterioration of T and B cell immunity in adults with CVID. IRT improves the whole blood parameters and stimulates immunoglobulin M (IgM) production. The later effect supports the immunomodulatory feature of this therapy.

Activation-induced cytidine deaminase (AID) enables antibody diversity in B lymphocytes. It may also have an effect on MDS pathogenesis by causing somatic mutations and by inducing epigenetic changes in myeloid cells. This study aimed to compare AID expression of MDS patients with healthy controls, of MDS patients in different risk groups, and of MDS patients according to their treatment. ⋯ AID expression is increased in the peripheral blood of MDS patients compared to healthy controls. However, AID expression is not significantly different in “lower risk” and “higher risk” subgroups and in patients treated with hypomethylating agents. Increased AID expression may be an early step in MDS pathogenesis.

We aimed to investigate the associations between the radiographic phenotypes and the presence of metabolic syndrome (MetS) in patients with knee osteoarthritis (OA). ⋯ The prevalence of MetS is quite high in patients with knee OA and is particularly pronounced in patients with JSNdominant radiographic phenotype. Moreover, our results suggest that MetS is an independent risk factor for JSN-dominant knee OA in patients with no past medical history of DM.
