graves’ disease is an autoimmune disorder characterized by presence of antibodies directed against thyroid stimulating hormone (tsh) receptor or nearby region. other serological abnormalities like antibodies to double stranded dna (ds–dna) and antinuclear antibodies (ana) have also been observed. we studied antibodies to ds-dna and ana in our patients with graves’ disease and compared them with...

INTRODUCTION Rosacea is a common inflammatory disorder, characterized by a spectrum of facial manifestations. The clinical similarity to other dermatoses, like lupus erythematosus, might lead to misdiagnosis, particularly in patients with elevated antinuclear antibody titers. AIM To assess the frequency, titer and specificity of antinuclear antibodies in rosacea patients and correlate these f...

As Brittenham’ has reviewed in detail, the use of the oral iron chelator LI has been associated with significant clinical and animal toxicity. One of the more controversial issues surrounding the human use of LI has been the possible development of autoimmune phenomena as manifested by development of autoantibodies such as antinuclear antibodies (ANA). The Canadian group investigating LI did no...

Several studies reported the appearance of asthma and autoimmune conditions in the same patient, but the clinical significance of this association was not yet assessed. One hundred asthmatic patients were observed for one year evolution with death, severe exacerbations, intake of > 1000 micrograms of beclometasone or equivalent (high ICS) and FEV1 decline >100 ml, in relation with ANA (ELISA), ...

The adjoint Newton algorithm (ANA) is based on the firstand second-order adjoint techniques allowing one to obtain the ‘‘Newton line search direction’’ by integrating a ‘‘tangent linear model’’ backward in time (with negative time steps). Moreover, the ANA provides a new technique to find Newton line search direction without using gradient information. The error present in approximating the Hes...

BACKGROUND With the emergence of biotherapies, accurate diagnosis in early arthritis is needed. At this time, there is no biological marker of psoriatic arthritis. OBJECTIVE To test whether antinuclear antibodies (ANA) can be used as a diagnostic tool in psoriatic arthritis (PsA), we evaluated the prevalence of ANA in biologic-naïve PsA patients and in healthy blood donors. METHODS 232 pati...

FcgammaRIIB is a potent lupus susceptibility gene as demonstrated by the observation that mice deficient in this molecule develop spontaneous antinuclear antibodies (ANA) and fatal glomerulonephritis when on the C57BL/6 background. To determine the mechanisms underlying the epistasis displayed by this gene we have constructed hybrids between FcgammaRIIB(-/-) and the systemic lupus erythematosus...

BACKGROUND The incidence of autoimmune diseases such as systemic lupus erythematosus, rheumatoid arthritis, and primary biliary cirrhosis has increased significantly in China. Information about the susceptibility or potential of autoimmune diseases in the general population is lacking. OBJECTIVE To explore the prevalence of antinuclear antibody (ANA) and its specificities in the general popul...

BACKGROUND Antinuclear antibodies (ANA) giving a rim-like/membranous (RL/M) or a multiple nuclear dot (MND) pattern are highly specific for primary biliary cirrhosis (PBC). Aim and SUBJECTS To assess the prevalence of PBC specific ANAs, their Ig isotype, and their clinical significance in 90 PBC patients from Greece and Spain. Twenty eight patients with chronic hepatitis C, 23 patients with s...

INTRODUCTION Patients with AIDS (acquired immunodeficiency syndrome) may have rheumatic complaints such as arthritis and arthralgia, dry eyes, increased salivary glands, lower back pain, enthesitis etc. Autoantibodies like ANA (antinuclear antibody) and RF (rheumatoid factor) may also be present. OBJECTIVE To study the prevalence of rheumatic complaints in AIDS patients and correlate them wit...
