OBJECTIVE The prevalence of some autoantibodies in the elderly population has been reported to be greater than in younger controls. The prevalence of ANCA has been shown to be low in a generally healthy population, but has not been established in the elderly. Thus, the presence of ANCA in elderly patients might not have the same clinical significance as in(More)
Seronegative myasthenia gravis (MG) presents a serious gap in MG diagnosis and understanding. We applied a cell based assay (CBA) for the detection of muscle specific kinase (MuSK) antibodies undetectable by radioimmunoassay. We tested 633 triple-seronegative MG patients' sera from 13 countries, detecting 13% as positive. MuSK antibodies were found, at(More)
Myasthenia gravis (MG) is an autoimmune disease caused by antibodies targeting the neuromuscular junction of skeletal muscles. Triple-seronegative MG (tSN-MG, without detectable AChR, MuSK and LRP4 antibodies), which accounts for ~10% of MG patients, presents a serious gap in MG diagnosis and complicates differential diagnosis of similar disorders. Several(More)
Cancer can occur in patients with inflammatory myopathies. This association is mainly observed in dermatomyositis, and myositis-specific antibodies have allowed us to delineate patients at an increased risk. Malignancy is also reported in patients with necrotizing autoimmune myopathies, but the risk remains elusive. Anti-signal recognition particle or(More)
OBJECTIVES Stavudine (d4T) is a potent but potentially toxic nucleoside reverse transcriptase inhibitor that is still widely used in developing countries. This study's aim was to determine the efficacy and safety profile of lower-dose d4T. METHODS Multi-centre, open-label, single-arm, pilot, 48-week study in French patients weighing >60 kg with viral load(More)
Intravascular malignant lymphomatosis is a rare and probably often overlooked disease characterised by massive intravascular proliferation of lymphoid cells, usually with a poor prognosis. CT and MRI appearances are nonspecific; the most suggestive finding being both asymmetrical, bilateral, contrast enhancing high-signal areas on T2 weighting and(More)
A 75-year-old female patient, without any relevant past medical history, was hospitalised on 25 September 1995 with a 1-year history of pelvic and shoulder pain, contact scalp pain and headache. These symptoms were developing in a context of general deterioration (weight loss, 4 kg), asthenia and subfebrile episodes. The cause of this trouble was at first(More)
