ABSTRACT

To report the presence of ANCA with an unusual polyreactivity. 50 year-old woman with pulmonary fibrosis whose immunological investigations showed the presence of ANCA with an unusual polyreactivity against several neutrophil proteins [PR3,MPO, BPI, lysozyme, elastase and cathepsine G] which could be related to a polyclonal hypergammaglobulinemia occurring in this patient. The international consensus on the testing of ANCA recommends seeking major specificities like MPO and PR3 which are good markers of ANCA-associated vasculitides. The use of multiantigenic ELISA can be helpful to detect various target antigens at the same time and may thus explain some atypical fluorescent patterns observed when searching for ANCA by Indirect immunofluorescence, these results, however, must be interpreted with caution

ABSTRACT

Late onset systemic lupus erythematosus [SLE] after 50-year-old is rare. We report a case of 84-year-old woman presenting with systemic lupus revealed by pleural effusion associated with renal involvement. The pleural effusion, renal abnormalities and the immunological abnormality improved within 4 weeks after prednisone therapy [1 mg/kg/day]. The late onset lupus differs from those with early onset, in terms of mild clinical presentation and favourable prognosis. Our observation is exceptional due to the very late onset of the lupus and involvement of a major organ, the kidney, which is usually exceptional in this age

ABSTRACT

Type I hypersensitivity is a major problem in public health, often requiring numerous investigations which aim to diagnose atopy and identify the causative allergen. Among these investigations, several blood tests,mostly using immunoenzymatic methods,can be performed to measure total and specific IgE levels. Type I hypersensitivity can also be investigated with assays which quantitate several mediators released after cellular activation induced by allergens
