A three-generation Muckle-Wells syndrome family: Detailed family history, physical examination, and inter-departmental collaboration.

Cryopyrin-associated periodic syndrome (CAPS) is a rare inherited autoinflammatory disease caused by gain-of-function mutations in the NLRP3 gene, with a genotype-phenotype correlation. The clinical presentation of each mutation has been previously studied. However, very few studies have reported on the clinical characteristics and treatment effectiveness across different generations within a family with the same mutation.

Tonsillitis-Related Arthritis: Advanced Understandings of Tonsillitis and Sterile Inflammatory Arthritis.

A 49-year-old man developed acute aseptic arthritis of the nonmigratory and asymmetrical type in his knee, ankle, and bilateral metatarsal joints 13 days after treatment with antibiotics for acute tonsillitis. He was diagnosed with tonsillitis-related arthritis after other rheumatic diseases were ruled out. Treatment with salazosulfapyridine, methotrexate, and methylprednisolone for 3 months did not completely improve.

The efficacy of mizoribine for the treatment of rheumatoid arthritis and its correlation with renal function.

Objectives: To evaluate the correlation between the efficacy of mizoribine (MZR) and the factors that might effect MZR concentration: renal function and dosage and administration of MZR in patients with rheumatoid arthritis (RA).

Methods: The efficacy of MZR treatment was prospectively evaluated in 97 RA regardless of dosage, at the 14 participated institutions. The Disease Activity Score 28-CRP3 was used to assess RA activity.

Antineutrophil cytoplasmic antibodies against myeloperoxidase, proteinase 3, elastase, cathepsin G and lactoferrin in Japanese patients with rheumatoid arthritis.

Antineutrophil cytoplasmic antibodies (ANCAs) against myeloperoxidase (MPO), proteinase 3 (PR-3), lactoferrin (LF), cathepsin G (CG) and elastase (EL) were determined to investigate whether the presence of ANCAs is closely related to extra-articular manifestations in Japanese patients with rheumatoid arthritis (RA). Antibodies against MPO, PR-3, LF, CG and EL were determined in sera from 125 patients with RA and 83 sera from patients with other rheumatic diseases by enzyme-linked immunosorbent assay. Clinical manifestations and laboratory parameters of the patients were studied from medical records.
