Clinical Trial
Safety and efficacy of etanercept in children with juvenile idiopathic arthritis below the age of 2 years.
Etanercept is approved for the treatment of patients with juvenile idiopathic arthritis (JIA) above the age of 2 years. Experience with younger children is limited. The aim of the present study was to evaluate the efficacy and safety of treatment with etanercept in children with JIA younger than 2 years. ⋯ Reasons for discontinuation were inefficacy in three (2 sJIA), intolerance in two, remission in three (2 sJIA) and the parents' request in one patient. Etanercept seems to improve JIA patients younger than 2 years including some of the patients with sJIA. Attention should be paid to the development of malignancies and autoimmune disorders.

Familial Mediterranean fever (FMF) is an autosomal recessive disease characterized by recurrent attacks of serosal membranes. In this study, 103 unrelated Syrian children were included. Mutation screening of the MEditerranean FeVer gene was performed for 12 mutations. ⋯ The most frequent mutation was M694V. In order to determine the association between M694V and clinical features of FMF, we compared the disease features between patients with and without this mutation. The presence of M694V was found to be associated with more severe course of FMF, earlier age of onset and more frequent arthritis in the Syrian children with FMF compared to other FMF patients who do not have this mutation.

Observational Study
Effects of an exercise therapy protocol on inflammatory markers, perception of pain, and physical performance in individuals with knee osteoarthritis.
Establishing prevention and therapeutic strategies for osteoarthritis (OA) is necessary to minimize functional disability and the impact of the disease on society. The aim of this study was to determine the effects of an exercise therapy protocol on inflammatory markers, perception of pain, and physical performance in individuals with OA of the knee. The protocol consisted of flexibility training and muscle strengthening over 12 weeks with three 80-min sessions per week. ⋯ The training also promoted an increase in the progression load for all muscles groups analyzed (p < 0.001). Our data suggest that the exercise therapy protocol could be a strategy for reducing IL-6 levels, managing pain, and improving function in individuals with OA of the knee. However, more studies are necessary to investigate the issue.

Observational Study
Incidence of herpes zoster infections in juvenile idiopathic arthritis patients.
The risk of herpes zoster among patients with juvenile idiopathic arthritis (JIA) exposed to biologics has not been evaluated. We determined incidence rates of herpes zoster among children with JIA in correlation with medication at time of occurrence and total drug exposure. The German biologics register database was used to identify patients with herpes zoster. ⋯ In comparison with our control group of patients treated with methotrexate, the IRR was higher for exposure to etanercept monotherapy and combination of etanercept and corticosteroids irrespective of methotrexate use. A generally higher incidence rate in JIA patients treated with etanercept was observed. No serious or refractory manifestations occurred.
