This study of children with chronic arthritis confirms that patients at greatest risk for chronic iridocyclitis have a young age of onset and positive antinuclear antibodies (ANA). Children who are ANA negative have a low risk of iridocyclitis. When it occurs it is at a significantly older age. No child developing juvenile chronic arthritis over 9, even with positive ANA, had chronic iritis. Th...

BACKGROUND Children are commonly referred to a pediatric rheumatology center for the laboratory finding of an Anti-nuclear antibody (ANA) of undetermined significance. Previous studies regarding adult rheumatology patients have supported an association between ANA and anti-thyroid antibodies, with the prevalence of thyroid antibodies being significantly higher in patients referred to a rheumato...

OBJECTIVE Recent studies suggest antinuclear antibodies (ANA) may be related to mortality risk, but evidence is sparse and inconclusive. Thus, we investigated ANA associations with all-cause and cause-specific mortality in U.S. adults. METHODS Our sample included 3357 adults (ages ≥20 years) from the 1999-2004 National Health and Nutrition Examination Survey with ANA measurements (1:80 diluti...

Objective: Although osteoarthritis (OA) is widely accepted as a degenerative disease, autoimmune processes are believed to be involved in the pathogenesis. There are limited studies in this area and most of them focused on antibodies against chondrocyte membrane. In an attempt to address the paucity of evidence in this regard, we explored the clinical significance of antinuclear antibody (ANA) ...

We examined the prevalence of anti-nuclear antibodies (ANA) in 32 consecutive patients with premature ovarian failure with and without chromosomal abnormalities. Blood samples were taken for karyotype determination as well as detection of autoantibodies, X-terminal microdeletions and spontaneous follicular growth. The correlation between ANA positivity and the age at onset of amenorrhoea, as we...

BACKGROUND Immunopathological and inflammatory processes play important roles in the initiation and development of ischemic heart disease. Hence, this study aimed to evaluate the relationship between serum levels rheumatoid factor (RF) and anti-nuclear antibodies (ANA) and severity of coronary stenotic lesions. METHODS Totally 140 patients with acute coronary syndrome (ACS) (n = 70) and chron...

Results 363 patients were included. 66% had JIA, 11% JSLE, 7% juvenile undifferentiated autoimmune disease(JUAD), 4% Scleroderma, 4% JDM, 1% uveitis ANA + and a group of other PAID 11%. ANA positivity varies according to the subtype of JIA from 0-68%. Positive AAN: JSLE 93%, scleroderma 85%, JDM 63%. Most JUAD had ANA + at low titers. A heterogeneous group of other PAID showed a variable titers...
