Evidence for an association between rheumatoid arthritis and autoimmune endocrine disease.

Association of PTPN22 rs2476601 Polymorphism with Rheumatoid Arthritis and Celiac Disease in Khuzestan Province, Southwestern Iran

Background: Single-nucleotide polymorphism (SNP) rs2476601 within protein tyrosine phosphatase non-receptor type 22 gene (PTPN22) has been shown to be a risk factor for different autoimmune diseases. This study explored the association of 1858 C/T SNP with rheumatoid arthritis (RA) and celiac disease (CD) in a region covering south-west of Iran. Methods: Totally, 52 patients with CD, 120 patien...

Lack of Association between PTPN22 (+1858 C>T) rs2476601 polymorphism and susceptibility to rheumatoid arthritis (RA) in Northeast of Iran

Background and objectives: Rheumatoid arthritis (RA) is an autoimmune disease with a complex genetic background. The protein tyrosine phosphatase non-receptor type 22 (PTPN22) is a lymphoid specific protein tyrosine phosphatase which is involved in negative regulation of T cell response. Several studies have assessed the association between PTPN22 single nucleotide polymorphisms (SNPs) with RA ...

Studying the Association between STAT4 Gene Polymorphism and Susceptibility to Rheumatoid Arthritis Disease: An Updated Meta-Analysis

Autoimmune diseases co-occurring within individuals and within families: a systematic review.

BACKGROUND Autoimmune diseases have been observed to coexist both within individuals and within families. It is unclear whether clinical reports of comorbid autoimmune diseases represent chance findings or true associations. This systematic review evaluates the current level of evidence on the coexistence of selected autoimmune diseases within individuals and families. We reviewed the associati...

Association between obesity types and anthropometric indices with rheumatoid arthritis disease

Background: Obesity is one of the causes of onset and exacerbation of rheumatoid arthritis. However, limited studies have examined the association between body composition and severity of disease. The aim of this study was to evaluate the association between severity of rheumatoid arthritis with various types of obesity and the comparison of anthropometric indices between patients with rheumato...
