Sera of some patients with systemic lupus erythematosus and related diseases contain a polyclonal antibody population (cross-reactive antinuclear antibodies [X-ANA]) that react specifically with both core mononucleosomes and plasma membranes of viable nucleated cells. Native mononucleosomes and nucleosome cores assembled from long DNA and the inner histones were indistinguishable in terms of in...

A case of a 42-year-old female with hyperthyroidism was subsequently diagnosed to have systemic lupus erythematosus with distal RTA. The clinical examination on admission showed swelling of the knee joints and the urinalysis showed pH 6.5, pro 3+. Her blood routine results were as follows: white blood cells 1.85×109/L, platelets 100×109/L, erythrocyte 3.06×1012/L. The serum potassium was 3.11 m...

SUMMY A 71-year-old man with paroxysmal atrial fibrillation who had a previous anterior myocardial infarction exhibited granulocytopenia 8 days following the administration of oral sustained-release procainamide (750mg/day). The plasma concentrations of procainamide and N-acetyl procainamide were at subtherapeutic levels. Discontinuation of procainamide led to complete recovery. A bone marrow a...

An 11-year-old boy presented in February 2008 with a facial butterfly rash that persisted for at least one month. Lupus erythematosus was repeatedly suspected and the boy was referred for further examinations. A detailed medical history did not reveal any arthralgia, fever, malaise, exanthema, intense exposure to ultraviolet (UV) light in the period one to three weeks before onset of the rash. ...

Dr. L. Misery, Dr. P. Combemale, Service de Dermatologie, HIA Desgenettes, Boulevard Pinel, F-69003 Lyon (France) We have seen unusual adverse reactions to BCG vaccination in a 21-year-old man with personal and familial atopy. There was no history of tuberculosis nor exposure to individuals with known tuberculosis. BCG vaccination was performed because his tuberculin test was negative. One mont...

Our purpose is to explore whether anti-dsDNA antibody, which was demonstrated to enter living cells and induced apoptosis, could adversely affect reproductive outcomes. A total of 259 women receiving the in vitro fertilization-embryo transfer (IVF) cycle were enrolled in this study, including 52 women with positive ANA and anti-dsDNA (ANA+/anti-dsDNA+ group), 86 women with positive ANA and nega...

BACKGROUND AND OBJECTIVES Autoantibodies are immunglobulins occurred directly against autoantigens that are known as endogen antigens. Autoimmune disease is an occasion that the body begins a fight against its own cells and tissues. The antibodies that are created by the body against its own cell nuclei are called as anti-nuclear antibodies (ANA), and one of the methods used for detection and p...

OBJECTIVE Paraneoplastic neuropathy is a clinical and immunological heterogeneous disorder and attempts have been made to classify subgroups of this disease. Only 30-50% of the clinical defined cases have antineuronal antibodies. METHODS The clinical and immunological features of 36 patients with paraneoplastic neuropathy from the authors' database were analysed including the type and course ...

Our previous studies have shown that secreted extracellular matrix-associated protein Cysteine rich angiogenic inducer 61 (Cyr61), a novel proinflammatory factor, is involved in the pathogenesis of rheumatoid arthritis (RA). However, whether Cyr61 has any effect in systemic lupus erythematosus (SLE) remains unknown. This study aims to assess the level of serum Cyr61 and to investigate the assoc...

Systemic lupus erythematosus (SLE) and myasthenia gravis (MG) are autoimmune diseases, whose association in the same patient is rarely reported. Both pathologies share the following characteristics: affect mainly young women; alternate exacerbation and remission periods; and have positive antinuclear antibody (ANA) test. This case report assesses possible diagnostic hypotheses for the clinical ...
