Possible Association of Mutations in the Gene with the Intestinal Phenotype of Behçet's Disease and Refractoriness to Treatment.

Background: Mediterranean fever () gene mutations are responsible for familial Mediterranean fever (FMF) and associated with other inflammatory diseases. However, the effects of gene mutations on intestinal Behçet's disease (BD) are unknown. In this study, we investigated these mutations and clinical features in patients with intestinal BD.

Overlap syndrome involving anti-OJ antibody-positive polymyositis, systemic lupus erythematosus and Sjögren's syndrome: A case report and literature review.

Anti-OJ antibody is relatively rarely detected in patients with the anti-synthetase syndrome, which is polymyositis (PM)/dermatomyositis (DM) with anti-aminoacyl transfer ribonucleic acid (RNA) synthetase antibodies. There have been few case reports of anti-OJ antibody-positive PM/DM complicated by other connective tissue disorders. Herein, we report the case of a 33-year-old woman who was admitted to our hospital with fever, muscle weakness, and dyspnoea on exertion.

Low urine pH associated with sarcopenia in the elderly: A multi-center observational study.

The pathophysiology of sarcopenia is complex and must be further explored. While metabolic acidosis may be a risk factor for sarcopenia, it remains unclear whether acidic urine is related to sarcopenia. The purpose of the present study was to investigate the association between sarcopenia and urine pH in the elderly.
