Interest of Beta-2-Microglobilin Plasma Assay in Iterative Haemodialysis in the Nephrology and Haemodialysis Department of University Teaching Hospital of Point G, Bamako, Mali

Beta-2-microglobulin (B2M) is a low molecular weight polypeptide (11,800 Da) that exists in a free form and a form bound to cell membranes (light chains of HLA class I molecules). 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. Materials and Methods: This was a prospective and descriptive study from January 1st, 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. Results: 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%. Conclusion: 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.

Acute Renal Failure Secondary to Paracetamol Intoxication: A Case Report

Renal damage secondary to paracetamol intoxication is rare, estimated between 1% and 2% of intoxication cases. 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).

Kidney Damage during Sharp’s Syndrome: About Two Cases

Context: The coexistence in the same patient of a mixed connectivitis or Sharp’s syndrome is a rare eventuality. Objective: To underline the presence of this mixed connectivitis in our practice, whose prevalence remains unknown, particularly in Africa and more precisely in Mali. Case Presentations: We report two cases of Sharp’s syndrome in a 48-year-old man and a 40-year-old woman with impaired renal function. 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). Conclusion: 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.

Epidemiological and Clinical Profile of Patients Undergoing Primary Nephrological Consultation at the Fousseyni DAOU Hospital in Kayes, Mali

Introduction: The first nephrological consultation is often late, even in developed countries. This delay is related to the insidious nature of renal disease, the lack of qualified personnel and structures for the management of these conditions and the context of chronic insecurity in our country. In Kayes, there is no data related to the first consultations of patients with the nephrologist, hence the interest of this study, which aimed to describe the epidemiological and clinical characteristics of patients undergoing a first nephrological consultation in Kayes hospital. Materials and methods: This was a retrospective, descriptive study conducted from January 1 to December 31, 2020 at the nephrology unit of the Fousseyni DAOU hospital in Kayes. All patients received for nephrological consultation for whom a medical record was made were included. The following data were collected and analyzed: the specialty of the medical referent, the reason for consultation, sociodemographic characteristics and the renal assessment of patients. Patients who consulted for non-nephrological pathologies and those who had no medical record were not included. Results: We collected the records of 346 patients, composed of 180 (52%) women and 166 (48%) men, i.e. a sex ratio of 0.92. The age group [20 - 40 years] was the most represented, 107 cases or 30.9%, with a mean age of 48.84 ± 21.33 years and extremes of 1 and 90 years. Housewives were the most consulted population, 149 cases (41.33%). Patients consulted more between the months of January and February, 116 cases (33.5%), this period was followed by the months of October-December, July-September and April-June with respectively 94 cases (27.2%), 76 cases (22.0%) and 60 cases (17.3%). The patients were referred by the general practitioner in 59.5% (209 cases), specialist doctor, 26.0% (90 cases). The patients came mainly from hospital practitioners, 172 cases (49.7%), private clinic and practice 81 cases (23.4%), community health center (CSCOM), 69 cases (19.9%). The main reasons for consultation were hypercreatinemia 205 cases (59.2%), low back pain 46 cases (13.3%) and edematous syndrome 16 cases (4.6%). The mean blood pressure was 140/80 mmHg with extremes of 70 and 240 mmHg for systolic and 40 and 160 mmHg for diastolic. Mean creatinine was 660.53 μmol/l ± 821.311 with extremes of 46 and 5447 μmol/l. Patients transferred from the emergency department had a creatinine level above 700 μmol/l in 41.1% (39) of cases (p = 0.003 Person’s Chi-square = 8643 ddl = 1). Among the 316 patients who had a blood count, anemia was found in 221 (69.9%) and the mean hemoglobin level was 9.61 g/dl ± 3.11 with extremes of 1.70 g/dl and 19.56 g/dl. The diagnostic hypotheses evoked were acute renal failure (124 cases, i.e. 38.5%), chronic renal failure (81 cases, i.e. 23.7%). Conclusion: Primary nephrological consultation is more solicited by general practitioners. The consultations, often in the emergency room, were motivated by significant hypercreatinemia. Awareness of the nursing staff, the patients and the political authorities are necessary to encourage nephrological consultations at an early stage of the renal disease.

Severe Thromboembolic Complication Revealing a Nephrotic Syndrome Due to Segmental and Focal Hyalinosis: A Case Report

Adult Nephrotic Syndrome (NS) is defined by proteinuria > 3 g/24h or 50 mg/kg/day, hypoprotidemia < 60 g/24h, hypoalbuminemia < 30 g/L. It is a disease with high thromboembolic risk. Peripheral vein thrombosis is common, while its association with pulmonary localizations has been more rarely reported. We report a case of nephrotic syndrome revealed by an association of pulmonary embolism, renal vein and inferior vena cava thrombosis. The diagnosis was confirmed by thoracic angioscan. Renal biopsy revealed Focal Segmental Hyalinosis (FSH). An anti-coagulant treatment and an anti-proteinuric treatment were instituted based on a calcium channel blocker (amlodipine) associated with the conversion enzyme inhibitor (perindopril).

Digestive Pathologies during Chronic Renal Failure in the Nephrology and Haemodialysis Department at the University Hospital Center of Point G in Mali

Introduction: Chronic kidney disease (CKD) is the progressive and irreversible loss of kidney function. It exposes to many complications, among which, digestive complications. In Mali, we do not have data on the prevalence of digestive pathologies in people with chronic renal failure, hence the interest of this study. Objective: To determine the prevalence of digestive pathologies and to describe their manifestations during chronic renal failure. Patients and Methods: This was a prospective cross-sectional study conducted from September 2016 to August 2017, a period of 12 months. Included were patients hospitalized in our department with CKD who received digestive endoscopy and/or liver serology. Results: Seventy-one patients underwent digestive endoscopy with oesogastroduodenal fibroscopy (60 patients), rectoscopy (6 patients) and anoscopy (5 patients), i.e. 15.9% of those hospitalized. The mean age of the patients was 48 ± 14 years with extremes of 15 and 84 years. The sample consisted of 59.2% men versus 40.8% women, for a sex ratio of 1.5. The functional signs are in order of frequency: vomiting (72.4%), anorexia (51.3%) and epigastralgia (48.7%). Terminal CKD by creatinine clearance accounted for 88.2% of cases, of which 47.4% were monitored by hemodialysis. Hepatitis C virus infection was present in 21.3% of cases, hepatitis B (18%) and HIV (7.5%). Endoscopic examinations were represented by fibroscopy (84.5%), rectoscopy (8.5%) and anuscopy (7%). The fibroscopic lesions were respectively gastric (96.8%), duodenal (14.1%) and esophageal (12.5%). They were dominated by gastritis (40.5%), duodeno-gastric reflux (16.4%), pyloric gap (12.6%). Rectoscopy found 4 cases of hemorrhoids, 2 cases of rectitis and no lesions were observed at anuscopy. Conclusion: The prevalence of these digestive manifestations and the endoscopic lesions encountered indicate the importance of digestive endoscopy and the performance of hepatic serologies in chronic renal failure patients with digestive symptoms and/or treated by hemodialysis.
