Epidemiological and Clinical Aspects of Chronic Renal Failure in the Medical Department at the Hospital of Sikasso

Introduction: Chronic renal failure is a real public health problem because of its prevalence, the cost of its management and the high morbidity and mortality rate associated with it. The objective of this study was to determine the frequency, causes and main aggravating factors of chronic renal failure in the medical department of the hospital of Sikasso. Materials and Methods: This was a cross-sectional, retrospective, descriptive study conducted in the medical department of the Sikasso hospital from January 1, 2021 to November 30, 2022. It covered all the records of patients with chronic renal failure hospitalized in the department during this period. The MDRD formula was used to estimate the glomerular filtration rate. The KDIGO 2012 classification was used to stage CKD. Results: Of 820 patient records reviewed, we retained 197 records. The mean age of our patients was 42.25 ± 10 years. The male sex represented 114 (57.9%). The socio-economic level was considered low and precarious in 79.8% of cases. The frequency of chronic renal failure was 24%. The reason for hospitalization was mostly hyper creatinine > 185 μmol/l (92.4%). Herbal medicine was reported in 103 cases (52.3%). Medical history was hypertension 101 cases (51.3%), undocumented gastro duodenal ulcer (UGD) 14 cases (7.6%), hypertension and diabetes 11 cases (5.1%), diabetes 8 cases (4%), lower limb edema 9 cases (4.6%). Hypocalcemia was 147 cases (75.6%) with hyper phosphoremia was 153 cases (77.7%). Hemoglobin level was: <6 g/dl, 44 cases (22.3%);between 6 - 8 g/dl, 77 cases (39.1%), from 8 - 10 g/dl, 54 cases (27.4%). The etiologies of CKD were vascular nephropathy 106 cases (53.8%), interstitial nephropathy, 44 cases (22.3%), glomerular nephropathy, 33 cases (16.8%), diabetic nephropathy, 12 cases (6.1%) and polycystic kidney disease 2 (1%). CKD was classified as stage 5, 171 cases (86.8%), stage 4, 11 cases (5.6%), stage 3, 13 cases (6.6%) and stage 2, 2 cases (1%.) Dialysis was performed in 1095 (5.3%) of our patients. All these patients started dialysis with a central line. Conclusion: This study reveals the high prevalence of chronic renal failure in the department and above all the late diagnosis at very advanced stages. This imposes policies of prevention and effective management of the responsible diseases.

Prevalence of Severe Anemia (Hb ≤ 5 g/dl) in Non-Dialyzed Chronic Renal Failure Patients in the Nephrology and Hemodialysis Department of Point G University Hospital

Introduction: Chronic renal failure (CRF) is defined as glomerular filtration rate (GFR) less than 60 ml/min/1.73m2 for at least three (3) months. Anemia is one of its most common complications. Anemia increases the risk factor for cardiovascular mortality by 18% per gram of hemoglobin loss. Objectives: To determine the prevalence and characteristics of this severe anemia, to determine the indications for transfusion, the complications related to this anemia, the evolution and the prognosis of these patients. Materials and Methods: This was a descriptive study with retrospective data collection over 18 months (January 1, 2017 to June 30, 2018) that included hospitalized CRF patients. Were included, non-dialyzed chronic renal failure patients with Hb ≤ 5 g/dl hospitalized during the said period. Not included were chronic renal failure patients with an Hb level ≥ 5 g/dl, those followed up and/or hospitalized outside the study period. Results: Among 1176 patients, 26 had severe anemia (Hb level ≤ 5 g/dl) on CRF, a prevalence of 2.21%. The mean age was 40 years ± 32.62 with extremes of 15 and 67 years. Seventeen women and 9 men. The etiology of chronic renal failure (CRF) was hypertensive vascular nephropathy in 50% of cases. CRF was end-stage in 18 patients (69.2%). The mean hemoglobin level was 4.10 g/dl ± 0.64 with extremes of 2 and 5 g/dl. The anemia was microcytic hypochromic in 50% and aregenerative (96.2%). The main symptoms were asthenia in 20 cases (76.9%), dizziness in 20 cases (76.9%), exertional dyspnea in 19 cases (73.1%). Signs of cardiac decompensation (n = 12) were jugular turgor 10 cases (38.5%), hepato-jugular reflux 06 cases (23.1%), mitral insufficiency murmur 06 cases (23.1%). The main complication was left ventricular hypertrophy 17 cases (77.3%). There was no correlation between anemia and sex (p = 0.291), age (p = 0.778), malaria (p = 0.158), etiology of CRF (p = 0.26). The evolution after treatment of anemia was favorable in 19 patients (73.1%), unfavorable in 02 patients (7.7%) and 05 deaths (19.2%). The deaths were of cardiovascular cause: left ventricular insufficiency 04 cases, stroke 01 case. Conclusion: Anemia is frequent in patients with chronic renal failure and remains an important risk factor for cardiovascular disease and poor general condition.

Parathyroidectomy in Chronic Haemodialysis in the Nephrology and Haemodialysis Department at the University Hospital Center of Point G in Bamako, Mali

Introduction: Secondary hyperparathyroidism is a common complication in chronic hemodialysis patients. It is characterized by hypersecretion of parathormone by the parathyroid glands to maintain phosphocalcium homeostasis in response to hypocalcemia, lowering of 1.25 dihydroxy vitamin D3 and hyperphosphatemia. Objective: To analyze the results of parathyroidectomy (PTX) in cases of secondary hyperparathyroidism (HPTS), report the post-operative course and early and late complications. Patients and Methods: We conducted a retrospective study of ten (10) patients with chronic renal failure operated on at the CHU of Point G over a 32-month period, from January 1, 2016 to August 31, 2019. We analyzed the clinical, biological, radiological and histological parameters of the thyroid glands. Results: We have collected 33 cases of secondary hyperparathyroidism. Ten (10) patients met the inclusion criteria. They were 45 years old on average, seven (7) women and three (3) men, in dialysis for an average of 6.8 years before parathyroidectomy. Half of the initial kidney disease was of vascular origin (HTA). No cases of diabetic nephropathy were identified. Symptoms were in order of frequency: bone pain (60%), paresthesia (50%), functional impotence of the lower limbs (50%). Radiological signs included demineralisation (5 out of 6 cases) and brown tumour associated with a fracture (1 out of 6 cases). The most frequent indication for parathyroidectomy (100%) was persistence despite treatment of a serum PTH concentration above 1000 pg/ml. Subtotal PTX (7/8) was performed after cervical ultrasound in all patients. Histological analysis of the parathyroid glands showed adenoma (60%) and hyperplasia in 40% of cases. The evolution was marked by a progressive reduction of the parathormone level over twelve (12) months, without achieving normalization. This could be related to sub-dialysis (generator failure with reduction of dialysis time). There were no cases of complications or mortality. Conclusion: Parathyroidectomy is an effective treatment to curb hypersecretion of parathyroid hormone. Despite this satisfactory result, the management of phosphocalcic abnormalities in renal failure remains an ongoing concern.

Prevalence and Etiologies of Obstructive Renal Failure in the Nephrology Department of the University Hospital Center of Point G, Bamako, Mali

Introduction: Obstructive renal failure (ORF) or obstructive uropathy is defined by the simultaneous presence of impaired renal function and urinary excretory tract dilatation on medical imaging. It accounts for 2% to 10% of the causes of acute renal failure (ARF). Objective: To determine the prevalence and etiologies of ORF in the nephrology department of the University Hospital Center of Point G. Methodology: This was a descriptive study with retrospective data collection conducted from January 1, 2017 to June 30, 2018. All patients hospitalized with renal failure due to urinary tract obstruction were included. The parameters studied were age, gender, etiology, type of renal impairment, procedures performed, surgical outcomes of the procedure, pre-and post-management creatinine levels. Information on these clinical and paraclinical variables was collected from individual hospitalization and patient follow-up records. Results: Among 1133 patients, 83 had obstructive renal failure, a prevalence of 7.32%. The sex ratio was 1.86. The mean age was 48.99 ± 6.81 years with extremes of 7 and 102 years. Signs suggestive of lower urinary tract obstruction were, in order of frequency: dysuria (50.6%), urinary burns (44.6%), urinary frequency (44.6%), pollakiuria (44.6%), macroscopic hematuria (25.3%), low back pain (21.6%), total anuria (18.1%). The etiologies were dominated by lithiasis 36 cases (43.4%), tumours 32 cases (38.55%) followed by sequelae of bilharziasis 12 cases (14.50%). Conclusion: Obstructive renal failure is becoming more and more common. The etiology is essentially of lithiasic and tumor origin. It must be treated early to allow total or partial recovery of renal function.

Result of 10 Years of Experience in Echo-Guided Kidney Biopsy Punctures in the Nephrology Department of the Martigues Hospital Center, France

Introduction: Percutaneous renal biopsy (PRB) is an essential procedure for the diagnosis and therapeutic management of many primary or secondary nephropathies. Objectives: To identify the indications, to determine the profile of the diagnosed nephropathies and to evaluate the short-term complications related to the practice of echo-guided PRB at the Martigues hospital center. Methodology: This was a retrospective and descriptive study carried out on the records of patients who underwent echo-guided native kidney biopsy from January 1, 2010 to December 31, 2019 in the nephrology department of the Martigues Hospital. Results: The analysis of 123 cases of echo-guided PRB involved 76 men and 47 women with a sex ratio of 1.6. The mean age was 55.92 ± 17.80 with age extremes of 16 and 87 years. Glomerular syndromes were the main indication with 42 cases of nephrotic syndrome (34.1%), 15 cases of nephritic syndrome (12.2%), 11 cases of rapidly progressive glomerulonephritis syndrome (8.9%), and 6 cases of recurrent macroscopic hematuria syndrome (4.9%). The histological findings were 47 cases of primary glomerular lesions (38.3%), 32 cases of nephroangiosclerosis lesions (26%), 24 cases of secondary glomerulopathy (19.5%), 9 cases of interstitial nephritis (7.3%), 2 cases of myelomatous nephropathy (1.6%), and 9 cases (7.3%) of unclassified histological lesions. Twenty-two hypertensive patients (40.7%) had nephroangiosclerosis lesions (p = 0.001). The follow-up was simple in 119 patients (96.7%). Macroscopic hematuria was noted in 4 patients (3.3%). It was associated with a perirenal hematoma in 2 patients including 1 transfused case. Conclusion: Our data provide an important contribution to the understanding of the prevalence and clinical presentation of renal diseases in the nephrology department of the Martigues hospital center.

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.

Prevalence of Cardiovascular Risk Factors in Chronic Hemodialysis Patients at the University Hospital Center of Point G in Bamako, Mali

Introduction: A cardiovascular risk factor (FDRCV) is defined as a physiological, pathological or environmental attribute or characteristic that results in an increased likelihood of developing cardiovascular disease in the individual in whom it is detected. The objective of this study was to determine the prevalence of cardiovascular risk factors in hemodialysis patients on hemodialysis at the University Hospital of Point G. Patients and Methods: This was a cross-sectional descriptive study with prospective data collection from March 3, 2009 to March 5, 2010 (13 months). Included were all patients with end-stage renal disease (ESRD) receiving chronic hemodialysis in the Nephrology and Hemodialysis Department of the University Hospital of Point G during the study period. Results: Eighty-eight patients were enrolled. The M/F sex ratio was 1.26. The mean age was 41.32 years with extremes of 17 and 81 years. The classic cardiovascular risk factors in order of frequency were: hypertension (90.9%), sedentary lifestyle (71.6%), male sex (54.5%), age ≥ 55 years (21.6%), obesity (13.6%), diabetes (8%), tobacco (8%), alcohol (3.4%). Cardiovascular risk factors related to CKD were: anemia (98.9%), phosphocalcic disorders (85.2%), arteriovenous fistula (AVF) (80%), lipid abnormalities (36.5%), hydrosodium inflation (29.5%). Predominant cardiovascular complications were hypertensive heart disease (62.5%), acute pulmonary oedema (APO) (50%), rhythm disorders (23.9%), coronary insufficiency (18.2%). The mortality rate was 17%. Conclusion: Cardiovascular risk factors are frequent in chronic hemodialysis. They contribute to the excess mortality of these patients. Adequate management of these risk factors can slow down serious cardiovascular complications and reduce the risk of mortality in this fragile population.

Diabetic Foot: Epidemiological, Therapeutic and Evolutionary Aspects in the Department of Medicine and Endocrinology of the Hospital in Mali, Mali

Introduction: The diabetic foot remains a public health problem due to its high frequency, difficult and costly management. The aim of this study was to determine the epidemiological, therapeutic and evolutionary aspects of the diabetic foot in a hospital setting in Bamako. Methodology: This is a retrospective, descriptive, cross-sectional and monocentric study conducted between September 1, 2011 and December 31, 2015 on diabetic patients aged 14 years and older arriving in our department with a foot infection. Results: We identified 94 cases of diabetic foot infection out of a total of 828 hospitalized patients, a prevalence of 11.35%. The age range 41 - 60 years represented 57 cases (60.6%), the extreme ages were 14 and 81 years. Men (38.3%), women (61.7%) with a sex ratio of 0.62%. Housewives 50%, illiterate 51 cases (54.3%), low economic standard of living 40 cases (42.6%), presence of osteitis 40 cases (42.6%), foot at stage D Grade3 28 cases (29.8%). Management was medical in 48 cases (51.1%), treatment with insulin 58 cases (61.7%), Amoxicillin + Metronidazole used 36 cases (38.29%). Amputation was performed in 35 cases (37.2%). Deaths concerned 5 patients (9.6%) with hypoglycemia as the main cause in 4 cases. Conclusion: Diabetic foot is a frequent complication of diabetes. The establishment of a multidisciplinary team should contribute to the improvement of the prognosis of the diabetic foot in a management center.

Diabetic Foot: Epidemiological and Clinical Aspects in the Department of Medicine and Endocrinology of the Hospital of Mali, Mali

Introduction: Diabetes is a heterogeneous group of metabolic diseases characterized by chronic hyperglycemia resulting from a defect in the secretion and/or action of insulin, diagnosed by the observation of high levels of glucose in the blood, responsible in the long term for vascular and nervous complications. The diabetic foot is the set of pathological manifestations affecting the foot in relation to the diabetic disease. Approximately 5% of diabetics present a chronic lesion of the foot. Objective: To describe the epidemiological and clinical aspects of the diabetic foot in the medicine/endocrinology department of the Mali hospital. Methodology: This was a retrospective descriptive study from November 2011 to December 2015. It focused on diabetic patients hospitalized in the department with a foot wound and aged 14 years and over. Results: The study involved 94 patients out of 828 hospitalized, a prevalence of 11.35%. Our series included 36 (38.3%) men and 58 (61.7%) women, i.e. a sex ratio of 0.61%. The mean age was 42.66 years with extremes of 14 and 81 years. Type 2 diabetes was present in 95% of the patients with a duration of evolution of more than 5 years in 60.6% of the cases. The mechanism of occurrence of the wounds was minor trauma in 54 cases (57.4%). Self-medication was the primary treatment in 70 patients (74.5%). More than 50% of the patients wore unsuitable footwear. Clinical and para-clinical examinations revealed isolated neuropathy in 37 cases (39.4%), necrotic wound in 37 cases (39.19%), poor glycemic control: HbA1c > 7% (98.9%), absence of osteitis (57.4%), normal Doppler ultrasound 45 cases (45.7%), stenosing arteriopathy 11 cases (22.3%), non-stenosing 3 cases (20.2%), germs present 56 cases (59.6%) including 21 cases (22.4%) of Staphylococcus aureus. Conclusion: Diabetes and diabetic foot constitute a real public health problem. They are responsible for dreadful and sometimes disabling complications. Its management is multidisciplinary and requires significant financial resources.

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.

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).

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).
