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.

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.

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.

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).

Bacteriological Profile of Pneumopathies in Chronic Renal Failure at the University Hospital Center of Point-G in Mali

Introduction: Chronic renal failure (CKD) is defined as a glomerular filtration rate (GFR) of less than 60 ml/min/1.73m2 for more than 3 months [1]. Infectious complications are a major source of morbidity in patients with chronic renal failure. In Mali, we have no data on pneumopathies in this population, hence the interest of this study. The objective of this work was to determine the frequency of pneumopathies in patients with chronic renal failure, describe the clinical radio-types, identify the microorganisms involved, and assess the renal prognosis of pneumopathies. Materials and Methods: This was an 18-month prospective and descriptive study from January 1, 2018 to June 30, 2019 conducted in the nephrology and hemodialysis department of the University Hospital of Point G. Included were patients hospitalized during our study period with CKD associated with pneumopathy on a chest X-ray. Not included were all patients hospitalized outside the study period, all CKD cases without pneumonia, patients with incomplete records, and non-consenting patients. Results: We examined 1111 patients, 35 of whom presented an image on chest X-ray related to pneumopathy, a frequency of 3.15% of cases. Twenty-one men (60%) and 14 women (40%) with a sex ratio of 1.5. The mean age was 46.8 ± 13.9 years with extremes of 23 and 76 years. The types of pneumopathy on the chest X-ray were: alveolar pneumopathy: 23 cases (65.7%), pleuropneumopathy: 10 cases (28.6%) and cavitary pneumopathy: 2 cases (5.7%). Cytobacteriological sputum examination was positive in 65.7%;leukocytes (68.6% of cases). The germs found were: Klebsiella pneumoniae (25.7% of cases), Escherica coli (11.4%), Pseudomonas aeruginosa (5.7%), Staphylococcus aureus (5.7%), Citrobacter freundi (5.7%), Enterococus sp. (2.9%), Enterobacter cloacae (2.9%), Candida albicans (5.7%). The search for acid-alcohol-resistant bacilli (BAAR) in sputum was positive in 4 cases (11.4%). There was an association between the results of cytobacteriological examination of sputum and the results of BAAR testing of sputum (p = 0.046).

Profile of Urinary Tract Infections in the Elderly in the Internal Medicine Department of the University Hospital Center of Point G, Bamako, Mali

Introduction: Urinary tract infections (UTI) are frequent and of polymorphous clinical symptomatology in elderly subjects both in and out of hospital. In Mali, to our knowledge, no study concerning UTIs in the elderly has been conducted, hence the interest in this innovative work. Objectives: To determine the prevalence and clinical and paraclinical aspects of urinary tract infections in the elderly. Materials and Methods: This was a prospective descriptive and cross-sectional study from September 1, 2013 to August 31, 2014, i.e. duration of 12 months. All patients aged 65 years and over, hospitalized or ambulatory in the internal medicine department with a documented urinary tract infection were included. Results: We collected and examined 194 patients. The cytobacteriological study of urine (CBSU) was positive in 28 patients, i.e. a prevalence of 14.43%. The male sex represented 59.8% of the cases, the sex ratio was equal to 1.46. The age groups between 65 - 69 and 70 - 74 years were the most affected, respectively 28.57% and 39.28%. The main clinical signs were: asthenia, anorexia, dependence, fever, urinary burning, dysuria. Hospitalization was associated with urinary tract infection with P = 0.01. The group of enterobacteria were incriminated in 75% of cases. Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa represented 39.28%, 14.28% and 10.71% of cases. Urinary tract infections were represented by pyelonephritis, acute prostatitis, orchi-epididymitis and simple cystitis. Conclusion: Urinary tract infection is frequent in the elderly, its clinical presentation is polymorphic and enterobacteria are the most incriminated group of bacteria.

First Consultation in Nephrology: Case of the Point G University Hospital (Bamako-Mali)

Understanding the first consultation of people with kidney disease seems to us to be essential to understand the attitude of the referring physician and the nephrologist. The aim was to find out to whom a patient with kidney disease should be referred in the first instance and for what reason? Hence the evaluation of the prevalence of the first consultation in the nephrology department of the Point G University Hospital in Bamako was made. Patients and Method: This was a prospective descriptive study which took place from July 2017 to June 2018 in the nephrology department of the Point G University Hospital. The study included all patients who came to the nephrology department for the first time during this period. Results: Between July 2017 and June 2018 at the nephrology and haemodialysis service of the G point University Hospital, we retained 643 out of 1031 patients who came for their first consultation, i.e. 62.36%. There were many patients aged between 41 and 50 years. The average age was 42.6 ± 5.03 years with extremes of 30 and 82 years. The sex ratio (M/F) was in favor of males, 1.14. The majority of patients were referred/evacuated from the referral health centres (57.6%). The majority of patients were referred/evacuated by general practitioners (70.5%). Cardiologists were the main specialists to refer/evacuate patients (21.2%). The main reasons for consultation that led to the first diagnostic hypotheses were: arterial hypertension for vascular nephropathy, glomerular syndrome for glomerular nephropathy, acute uraemia syndrome for acute renal failure, hydronephrosis for obstructive uropathy and finally diabetes for diabetic nephropathy. Conclusion: The first consultation in nephrology remains an important step in the management of renal disease, especially when the referral is an emergency. The percentage of referrals is dominated by general practitioners.

Erectile Dysfunction in Chronic Hemodialysis Patients at the University Hospital Center of Point-G in Mali

Introduction: Erectile Dysfunction (ED) is defined as the inability to achieve or maintain an erection sufficient for sexual intercourse. The frequency of erectile dysfunction in patients with kidney failure is estimated at 50% to 70%. The objective of this work was to determine the frequency of sexual dysfunction in chronic hemodialysis patients, to evaluate the psycho-social impact and to describe hormonal disturbances. Patients and Methods: This was a descriptive prospective study carried out from 3 April to 31 August 2017 in the nephrology and haemodialysis department of the Point G University Hospital. She has been interested in men over the age of 18 who have been on chronic hemodialysis for more than a year. Sexual dysfunction was assessed using the questionnaire: International Index of Erectile Function (IIEF-5). Results: Sixty-five patients were included. Forty-six (70.8%) had severe (30.8%), moderate (13.8%) and mild (26.2%) ED. 56.9% of patients had libido disorders, with decreased sexual desire (38.5%);absent sexual desire (18.5%). Sexual desire was normal in 43.1% of patients. Sexual activity was absent in 20 patients (30.8%). Sexual rigidity was reduced in 28 patients (43.1%) and normal in 24 patients (36.9%). The mean age of our patients was 42.55 years with a median age of 40 years and extremes of 23 and 74 years. Eighty percent were married. Nine patients (13.8%) were using sildenafil-based medications. Antihypertensives were prescribed in 93.9% and erythropoietin in 30.8% of patients. The main impact groups were anxiety (53.8%), fear of failure (27.7%), insomnia (7.7%) and anxiety (6.1%). And defence mechanisms included: understanding (54.7%);isolation (24.6%);repression (7.7%);quarrel (7.7%);and divorce in 1 case (1.5%). The occurrence of ED was related to hypotestosterolemia (p = 0.030), and between low libido and testosterone (p = 0.001). Nutritional status was satisfactory in 78.4% of our patients. Moderate and at and severe undernutrition was found in equal proportions (10.8%) in our patients with a statistically significant relationship with the occurrence of erectile dysfunction (p = 0.015). There was no correlation between ED and duration of dialysis (p = 0.715), the existence of inflammatory syndrome (p = 0.870), age (p = 0.249) and diabetes, hypertension, smoking (p = 0.442). Sexual activity was decreased in 41 patients with Hb 10 g/dl (p = 0.340). Conclusion: Sexual disorders are common in hemodialysis patients. Psychological support of the patient is essential throughout the therapeutic sequence of erectile dysfunction, whatever the molecule or physical means considered.

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.

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.

Renal Failure of Lithiasis Origin: Frequency and Management in the Nephrology and Haemodialysis Department of the Point G University Hospital in Mali

Background: The term urinary lithiasis (UL) from the Greek “lithos” refers to the disease characterised by the result of abnormal precipitation of normal constituents of the urine within the urinary tract. The aim of this work was to determine the frequency of obstructive renal failure (ORF) of lithiasis origin and to describe the therapeutic indications. Methods: This was a retrospective prospective study in patients hospitalised in the nephrology department of Point G University Hospital for ORF of lithiasis origin over a 26-month period from 1 January 2018 to 1 February 2020 inclusive. Results: Among 1898 hospitalized patients, 32 met the inclusion criteria, i.e. a frequency of 1.7%. The male sex was 68.75% with a sex ratio of 2.2. The mean age was 48.38 ± 13.423 years with extremes of 20 and 65 years. Dysuria and urinary bilharzia were the main uro-nephrological antecedents, accounting for 25% of the cases each. Pain syndrome was the main functional sign, accounting for 100%. Ultrasound of the urinary tract (n = 28) showed stones in 92.85%. These stones were bilateral in 22.22% of cases. The dilatation was pyelocalic in 14 cases (51.8%). The uroscanner showed a pyelic location of the stones in both kidneys;42.1% on the right and 33.3% on the left. Hydronephrosis was the most common dilatation: 37.8% on the right and 29.7% on the left. Renal lithiasis was complicated by acute kidney injury (ARI) in 17 cases (53.1%) versus 15 cases (46.9%) of chronic kidney disease (CKD). Urethral catheter was the means of drainage in 24 (75%) followed by nephrostomy in 8 cases (25%). Nephrolithotomy accounted for 9.4% of cases. The case fatality rate was 28.12% (9 cases). Deaths occurred in the context of uraemic coma 6 cases and cardiorespiratory arrest 3 cases. Conclusions: The management of urinary lithiasis complicated by renal failure calls for the correction of hydrolytic disorders, drainage of the excretory tract and treatment of the stone, of which percutaneous nephrolithotomy seems to be the modality of choice.

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.

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).

Sjögren’s Syndrome Revealed by Obstructive Renal Failure: A Case Report and Review of the Literature

Introduction: Primary Sjögren’s syndrome (SS) is the most common connective tissue disease after rheumatoid arthritis and affects mostly women between 30 and 40 years of age with an estimated prevalence between 0.1% and 0.6%. This observation illustrates an incidental finding of a case of SS in a young female patient in a context of obstructive renal failure (ARF) due to uterine fibroids. Observation: This was a 31-year-old woman hospitalized for anuric AKI (Acute Kidney Injury) with a creatinine level of 1247 μmol/l. Her history included sickle cell disease A/C and an unoperated uterine fibroid diagnosed 3 years ago. Approximately 2 months before her admission, her symptomatology was made of dizziness, physical asthenia, vomiting, poly-arthralgia, morning rash, pollakiuria and oral dryness. Abdominal examination showed a painless transverse mass in the pelvis. Biological examination showed a CRP (C-reactive protein) level of 488 mg/l. The cytobacteriological examination of the urine was normal and the proteinuria was 1.35 g/24 hours. The CT scan showed kidneys measuring 110 mm on the right and 113 mm on the left associated with bilateral pyelo-caliceal dilatation on a large polymyomatous uterus of interstitial and submucosal type. Immunologically, the anti-nuclear factor, the rheumatoid factor and the anti-SSA antibodies were positive. The resumption of the interrogation within the framework of the research of the subjective dry syndrome to find a notion of intermittent xerophthalmia 4 months ago. The Schirmer test was positive in the left eye. The initial management consisted of a polymyomectomy after 3 sessions of hemodialysis. Background treatment combining prednisone 5 mg/day and methotrexate 20 mg/week was started in parallel with the use of artificial tears. The evolution after twelve (12) months of treatment was favorable with a complete disappearance of the signs dry syndrome and full recovery of renal function. Conclusion: SS can have an insidious evolution and remain stable for many years, hence its fortuitous discovery in this case of obstructive ARF on uterine fibroid. In this context we insist on the interest of the immunological assessment in a patient in period of genital activity with a significant proteinuria and non-specific extrarenal signs.

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.

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.

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.

Centropontine Myelinolysis after Conservative Correction of Hyponatremia: A Case Report and Review of Contributing Factors

Introduction: Centropontine myelinolysis (CPM) is a rare pathology, a delayed neurological complication corresponding to massive demyelination of the protrusion. Its exact pathogenesis is poorly understood. Rapid correction of sodium hyponatremia has been implicated as a potent causative factor. We report a case of CPM despite a priori conservative correction of hyponatremia with a favorable course in a 61-year-old alcoholic-smoker diabetic. Case Presentation: A 61-year-old man with chronic alcoholism presented to the emergency department (D0) with physical asthenia and anorexia. He was treated for severe hyponatremia at 104 mmol/L by careful rehydration with saline before being transferred to a nephrological hospital. Magnetic resonance imaging (MRI) performed at D14 for locked-in syndrome showed osmotic demyelination syndrome (Figure 1). The evolution was favorable after 3 months of rehabilitation marked by a progressive and clear improvement of clinical signs. Conclusion: This observation suggests an evaluation of the benefit/risk ratio of the short-term prognosis of profound hyponatremia with that of the metabolic stress induced by a still too rapid correction. Particular attention should be paid to diabetic patients in the context of chronic alcoholism or nutritional deficiencies.
