Plasmapherisis

INTRODUCTION: Sars-CoV-2 induces an intense cytokine response called cytokine storm at the origin of acute respiratory distress syndrome, multiple organ dysfunction syndrome and death. In this context, several treatments have been proposed; and plasmapheresis appears as a promising treatment. CASE PRESENTATION: We report the case of a 57-year-old patient admitted for Sars-CoV-2 infection, who requiried the use of mechanical ventilation, assistance by veno-venous extracorporeal membrane oxygenation ECMO and treated by plasmapheresis plugged on the ECMO circuit...

Low density lipoprotein (LDL) apheresis is one of the main therapeutic models for homozygous and severe heterozygous form of the familial hypercholesterolemia patients. Anti-atherogenic, anti-thrombogenic and anti-inflammatory effects of apheresis has positive effects on prevention of cardiovascular disease by improving of the tissue perfusion. Blood LDL cholesterol levels, response to medical therapy, presence or severity of the coronary heart disease are the main determinants of the apheresis indications...

Anti-glomerular basement membrane antibody disease is a rare, but well characterized cause of glomerulonephritis. By definition serum anti-GBM antibody and/or a linear binding of IgG detected by direct immunofluorescence (IF) in a histological specimen of the kidney or the lung have to be detected. These antibodies can lead to acute rapid progressive glomerulonephritis(RPGN) and/or pulmonary hemorrhage (PH) because of collagen similarities in the basement membrane. Principally anti-GBM antibody disease can be divided into two groups: anti-GBM antibody disease without PH was regarded as renal-limited anti-GBM antibody disease and that with PH was defined as Goodpasture's syndrome (GPS)...

Respiratory involvement in systemic lupus erythematosus (SLE) is not as well-known as the cutaneous, rheumatological and renal manifestations. It occurs frequently but the diagnosis may be difficult because of the heterogeneity of the anatomical and clinical presentations. A precise diagnosis is crucial as new immunosuppressive drugs have considerably improved the prognosis. The pathology involves genetic, endocrine, environmental, pharmacological and immunological factors with a cytotoxic reaction of auto-antibodies against complement, a circulating immune complex reaction and a hyperactivity of B lymphocytes...

Chronic progressive polyneuropathy is frequently cryptogenic but occurs in association with monoclonal gammopathy. In cases of this type, a relatively mild, mainly axonal sensomotor neuropathy is frequently present and may be difficult to distinguish from carcinomatous neuropathy in malignant conditions without the presence of the M-component. In benign essential gammopathy (MGUS) with an M-component of IgM-kappa class, the neuropathy is frequently demyelinizing and the paraprotein reacts specifically with carbohydrate determinants in myelin-associated glycoprotein (MAG) and other glycoproteins and glycolipids in peripheral nerve tissue...
