Introduction: Peritoneal dialysis (PD) is an extra-renal purification technique indicated for patients with end-stage kidney disease (ESKD). Although it has many advantages, it also has a number of complications, such as peritoneo-vaginal leakage of dialysate. Cases Reports: Three male patients, aged 70, 50 and 77 respectively, with ESKD were placed on PD. All three patients presented with inadequate drainage and the progressive appearance of bilateral hydrocele, which occurred one year (late leakage), two and four days (early leakage) respectively after the initiation of exchanges. The etiological investigation led to the conclusion of a peritoneo-vaginal leak associated with an inguinal hernia in only one case. The two cases of early leakage were treated by temporary suspension of PD, with a good response in one case and failure in the second, leading to hisdefinitive transfer to hemodialysis (HD);however, the hernia repair enabled immediate resumption of PD in the third patient. Discussion and Conclusion: Peritoneo-vaginal leakage is a rare mechanical complication in PD. The clinical examination plays an essential role in confirming the diagnosis and in the therapeutic decision. If the diagnosis is uncertain, or if there is a clinical need to show the anatomy of the leak, an imaging approach becomes desirable. This complication should not prevent the progression of PD in the management of patients with ESKD.

Secondary hyperparathyroidism (HPT) is frequent in dialysis patients. Parathyroidectomy (PTX) is indicated for patients who failed medical therapy. We reviewed the data from 184 dialysis patients who underwent PTX between January 2015 and January 2023. We aimed to evaluate the short and long term outcomes of PTX in dialysis patients, comparing the conservative 3/4 versus 7/8 techniques in this population.166 dialysis patients with secondary HPT were included. A conservative subtotal PTX (sPTX) 7/8 was performed in 72% of patients and sPTX 3/4 in 28% of them. Severe postoperative hypocalcaemiaocurred in 45 patients (27%). Hypocalcaemia was significantly more frequent in the sPTX 7/8 group (p = 0.012). One case of persistent HPT (0.6%) and 20 cases of recurrence (12%) were diagnosed. Recurrence was more frequent in the sPTX 3/4 group (15%). No deaths were reported during the perioperative period.

Introduction: Studies have been conducted on nephrotic syndrome in Niger. The study aimed to determine the histological and etiological aspects of nephrotic syndrome. Patients and Method: This was a retrospective study from February 1st, 2018 to January 31st, 2024. All patients with nephrotic syndrome who underwent renal biopsy were included. Samples were analyzed at the anatomy-cytology pathology laboratory of the Faculty of Medicine in Dakar (Senegal). The variables studied included clinical, biological, histological and etiological characteristics. Data were analyzed using Excel 2013 and Epi-info 7.2.0 software. Results: The study included 119 patients with nephrotic syndrome. Prevalence of nephrotic syndrome was 11.24%. The male-to-female ratio was 2.25:1. The mean age at diagnosis was between 34.5 ± 18.84 years. Edema was the reason for admission in 40.34% of cases. The nephrotic syndrome was impure in 63.86% of cases. Nine histological lesions were identified. Focal and segmental glomerulosclerosis (40.09%), minimal change disease (23.53%), membranous nephropathy (13.45%), diabetic nephropathy (10.92%), membranous proliferative glomerulonephritis (3.36%), acute glomerulonephritis (3.36%), glomerular thrombotic microangiopathy (2.52%), non-IgA mesengial proliferative glomerulonephritis (1.68%) and amyloidosis (0.84%). Nephrotic syndrome was primary in 57.98% of cases. Secondary etiologies were dominated by diabetes (11.76%), followed by hepatitis B virus (9.24%), lupus, lymphoma, malaria, syphilis, cryoglobulinemia, sickle cell disease and HIV. Conclusion: Future studies should investigate the causes of glomerulopathy secondary to chronic tubulointerstitial lesions.

Infective endocarditis (IE) is a frequent complication in chronic hemodialysis patients (CHD). The repeated placement and manipulation of central venous catheters, underlying valvulopathies, and immunosuppression are the main predisposing factors for these patients to develop IE. We aimed to highlight the clinical and microbiological specificities of IE in CHD patients, detail the therapeutic management in these patients and identify the risk factors for in-hospital mortality. We included 28 CHD patients in whom the diagnosis of IE was established according to modified Duke criteria. The mean age was 47 ± 17 years. Among them, 57% were hypertensive and 39% were diabetic. The average duration of hemodialysis was 3.5 ± 7 years. The vascular access was a tunnelled jugular catheter, arteriovenous fistula, and temporary catheter in 54%, 28%, and 18% of patients, respectively. Half of the patients presented with heart failure at admission. Methicillin-sensitive Staphylococcus is the most commonly implicated pathogen. Transthoracic echocardiography revealed vegetation in all patients. In 60% of cases, the lesion is located on the mitral valve, and in 35% it is on the tricuspid valve. Patients initially received empirical antibiotic therapy, which was adjusted according to bacteriological results. Valve surgery was indicated in 12 patients, with aortic valve replacement being the most performed procedure followed by tricuspid annuloplasty. The in-hospital mortality rate was 32%. Factors associated with mortality were severe mitral insufficiency (p = 0.036), heart failure (p = 0.043), and the presence of Methicillin-resistant Staphylococcus in blood cultures (p = 0.047). IE is a complication with high morbidity and mortality. Its increasing incidence, specificities in chronic CHD patients, and the complexity of its management require a rigorous preventive strategy.

Introduction: Autosomal dominant polycystic kidney disease (ADPKD) is a common, multisystemic, and progressive hereditary disease. It accounts for 6 to 8% of incident cases of end-stage chronic renal disease (ESRD) in developed countries. The aim of this study is to describe the predictive factors for the development of end-stage chronic kidney disease (CKD) in the course of this disease. Material and Methods: This is a retrospective, descriptive, and analytical study including 300 cases of ADPKD collected at the Nephrology Department of Ibn-Sina Hospital in Rabat over a period of 30 years (1993 to 2023). Included in the study are all patients with ADPKD meeting the ultrasound diagnostic criteria. The analysis focused on demographic, clinical, paraclinical, evolutionary data, as well as prognostic factors associated with renal function deterioration. Results: The mean age of patients at diagnosis is 51.53 +/− 17 years [16 - 93] with a male predominance. The median serum creatinine at diagnosis is 15.5 mg/l [10 - 34]. 21% of patients had ESRD (eGFR 300 mg/24h (21%). The most common cystic complication is hemorrhage (12.3%). 21.3% of patients had hepatorenal polycystic disease. In adjusted analysis, the predictive risk factors for the occurrence of ESRD were smoking (p = 0.019), anemia (p Conclusion: ADPKD can progress insidiously to ESRD. Identification and early treatment of predictive factors for poor renal prognosis could contribute to a better outcome for this disease.

Introduction: Renal transplant artery stenosis (RTAS) is a common and early complication of renal transplantation, which can lead to severe post-transplant hypertension, as well as significant morbidity and mortality, particulary graft loss. The aim of this study is to determine the prevalence, clinico-radiological characteristics and evaluate the outcomes of luminal angioplasty as a first-line treatment for RTAS, through the analysis of medical records of 27 kidney transplant patients. Material and Methods: This is a retrospective, single-center, and descriptive study conducted at the Nephrology department of the Ibn-Sina Hospital in Rabat, including 27 renal transplant patients with RTAS during the period from 1998 to 2023. All patients with clinically suspected RTAS and confirmed by Doppler ultrasound of the transplanted renal artery were included in the study. Results: The mean age of donors was 48.66 ± 13.55 years, with a female predominance (65%). The donor was deceased in 15% of cases. The mean age of the recipients was 39 ± 16 years with a male-to-female ratio of 4.4. The median onset of RTAS was 3.6 ± 3.4 months after renal transplantation. Seven patients (26%) had high blood pressure (HBP) before their transplantation. Six patients (22%) had hypertriglyceridemia and 7 patients (26%) had pure hypercholesterolemia. The main clinical signs were worsening of preexisting HBP, de novo HBP and acute renal failure (ARF). Stenosis was confirmed by renal Doppler ultrasound in all patients. It was severe in 63%, with a stenosis degree greater than 70%. Six patients underwent angioplasty, resulting in the stabilization of graft function with a nadir of 15 mg/l creatinine and blood pressure control with dual therapy in 5 patients. No graft loss cases were noted. Conclusion: RTAS is a significant vascular complication of renal transplantation that predicts unfavorable outcomes for both the patient and the graft. Early diagnosis is crucial to successfully restore graft f

Introduction: Vaccination against COVID-19 has proven highly effective in preventing severe forms of the disease. However, the literature reports several cases associating renal damage and the anti-COVID vaccine. The aim of our work was to report a case series of patients who developed glomerulopathy after anti-COVID-19 vaccine. We evaluated the type of vaccine, the clinico-biological profile, and the anatomopathological, therapeutic and evolutionary aspects. Material and Methods: Prospective descriptive study conducted at the Nephrology Department of CHU IbnSina in Rabat between December 2021 and June 2022 including 9 patients who presented with glomerulopathy after the 1st dose of anti-COVID-19 vaccine. We excluded patients followed for nephropathy. Results: The mean age of our patients was 33 ± 16 years with a sex ratio of 0.8. Six patients received an inactivated vaccine, 2 patients received a mRNA vaccine and 1 patient received a viral vector vaccine. The mean delay between the onset of signs and the date of the first vaccine dose was 3.1 +/? 0.65 months (1 - 6 months). All patients had a nephrotic syndrome, 2 pure and 7 impure: 3 patients had acute renal failure and microscopic hematuria, 2 patients had microscopic hematuria and 2 patients had acute renal failure. Histologically, focal segmental glomerulosclerosis (FSGS) was noted in 4 patients, lupus nephropathy in 3, and membranous nephropathy (MN) in 2. Specific treatment was administered to each patient, depending on the histological type of renal involvement and the context. After 6 months, complete remission was achieved in 5 patients, with no improvement in 2, and one patient was placed on hemodialysis. One patient died of another cause. Conclusion: The causal link between anti-COVID 19 vaccination and renal disease is highly probable, but remains to be confirmed.
