Its pathophysiology is still debated, the clinical involvement consisting in an acute tubular necrosis with a good prognosis if it is rapidly treated. Renal damage can sometimes occur without prior hepatic damage, and the onset of renal manifestations is generally between the 2nd and 7th day after taking paracetamol. If its management remains exclusively symptomatic, its late onset can sometimes lead to serious metabolic complications. It is therefore important to systematically monitor renal function following paracetamol drug intoxication. We report the case of a 60-year-old male subject hospitalized for the management of voluntary drug intoxication (VDI) with paracetamol complicated by acute hepatocellular failure and acute renal failure. His management required extrarenal purification (hemodialysis) and the evolution was favorable with recovery ad integrumof renal function. Conclusion: Although less known and of unelucidated physiopathology, nephrotoxicity secondary to voluntary drug intoxication with paracetamol is a reality and can lead in extreme cases to the use of extrarenal purification technique (hemodialysis).展开更多

Their dosage is used in the exploration and monitoring of renal function in haemodialysis patients, hence the interest of this study, the objective of which is to study the different players involved in the increase of beta-2-microglobulin. <strong>Materials and Methods:</strong> This was a prospective and descriptive study from January 1<sup>st</sup>, 2017 to August 31, 2017 (08 months). All patients with chronic hemodialysis for 3 years or more were included. We analyzed sociodemographic, clinical and paraclinical data. <strong>Results:</strong> We collected 50 patients. The mean age was 50 ± 4.6 years with extremes of 30 and 82 years. The female sex predominated (52%). Chronic end-stage renal failure was hypertensive (86%), diabetic (4%). All patients benefited from intermittent hemodialysis for 8 hours per week using a low permeability membrane (cuprophane). The average duration of hemodialysis was 68 ± 6.4 months with extremes of 36 and 204 months. Twenty percent (20%) and four percent (4%) of chronic dialysis patients had joint pain and sensory deficit. Phalen’s sign was positive in 2% (1 case), Tinel’s sign in 2% (1 case) and carpal tunnel syndrome in 2% (1 case). The mean serum beta-2-microglobulin level was 58.34 ng/l with extremes of 16.99 and 112.24 ng/l. There was a correlation between hypertensive nephropathies and beta-2-microglobulin levels above 50 ng/l (P < 0.001). The mortality rate was 6%. <strong>Conclusion:</strong> Our study has objectified factors such as inadequate dialysis (8 hours/week), use of low permeability membrane in the increase of beta-2-microglobulin. The increase in serum beta-2-microglobulin levels in our patients is evidence of poor purification of medium molecules. Its reduction can be established by improving the quality of dialysis, in particular by using a high-permeability membrane.展开更多

The picture achieved associated massive proteinuria, hypoalbuminemia, moderate renal failure and edematous syndrome in men. In women, the picture was associated with accelerated to malignant hypertension and severe renal failure. There were no osteoarticular manifestations and the diagnosis of Sharp’s syndrome was based on the presence of high levels of antibodies to U1RNP. Therapeutic management has been that of predominantly associated connective tissue disease (systemic lupus erythematosus). <strong>Conclusion:</strong> Mixed connectivitis or Sharp’s syndrome is increasingly recognized as a separate entity thanks to advances in molecular biology. Its prevalence is low in sub-Saharan African countries with renal disease that manifests itself as proteinuria or nephrotic syndrome associated with microscopic hematuria, renal failure, and hypertension. This renal impairment is more likely to occur in severe forms of the disease.展开更多
