RESUMO
OBJECTIVE: To describe the epidemiological, clinical, paraclinical, therapeutic and evolutionary characteristics of of peripartum cardiomyopathy (PPCM) in the internal medicine department of the Zinder National Hospital (ZNH). METHODS: This was a descriptive cross-sectional study carried out from 2018 to 2022 at the ZNH Department of Internal Medicine. Included were all patients admitted for PPCM who met National Heart Blood and Lung Institute criteria. The data collected was analyzed using Excel and EPI INFO v7. RESULTS: We had collected 100 cases of PPCM out of a total of 8706 hospitalized patients, i.e. a hospital prevalence of 1.14%. The mean age of the patients was 27.9 years ± 7.4 [17-45]. The majority of patients were from underprivileged social strata (n=64). The risk factors for PMPC found were essentially hot bath (n=66), home birth (n=40), natron porridge (n=35) and multiparity (n=57). Cardiac symptomatology appeared postpartum in 56% of patients. Dyspnea was the main symptom in 98% of cases. The physical signs were dominated by the functional systolic murmur (66%). Three quarters (75%) of the patients had congestive heart failure. Electrocardiographic signs were dominated by left ventricular hypertrophy (n=65). Cardiomegaly was present in 94% of patients. Left ventricular ejection fraction was altered in all patients. Impaired renal function was found in 31% of patients. Management was based on a low-sodium diet tripod, diuretics and converting enzyme inhibitors. Two cases of death were recorded. CONCLUSION: PPCM is common in the Zinder region. It affects young women with several risk factors and is revealed by signs of congestive heart failure. For a better understanding of this still poorly elucidated condition, it is necessary to pursue research efforts.

The burden of chronic kidney disease and associated risk of kidney failure are increasing in Africa. The management of people with chronic kidney disease is fraught with numerous challenges because of limitations in health systems and infrastructures for care delivery. From the third iteration of the International Society of Nephrology Global Kidney Health Atlas, we describe the status of kidney care in the ISN Africa region using the World Health Organization building blocks for health systems. We identified limited government health spending, which in turn led to increased out-of-pocket costs for people with kidney disease at the point of service delivery. The health care workforce across Africa was suboptimal and further challenged by the exodus of trained health care workers out of the continent. Medical products, technologies, and services for the management of people with nondialysis chronic kidney disease and for kidney replacement therapy were scarce due to limitations in health infrastructure, which was inequitably distributed. There were few kidney registries and advocacy groups championing kidney disease management in Africa compared with the rest of the world. Strategies for ensuring improved kidney care in Africa include focusing on chronic kidney disease prevention and early detection, improving the effectiveness of the available health care workforce (e.g., multidisciplinary teams, task substitution, and telemedicine), augmenting kidney care financing, providing quality, up-to-date health information data, and improving the accessibility, affordability, and delivery of quality treatment (kidney replacement therapy or conservative kidney management) for all people living with kidney failure.
RESUMO
Kidney biopsy (KB) has become essential in the nephrologist's approach to kidney diseases, both for diagnosis, treatment, and prognosis. Our objective is to describe the preliminary results of KBs in Niger, one of the poorest countries in the world. This is a descriptive cross-sectional study that took place over 36 months in the nephrology/dialysis department of the Zinder National Hospital. Biopsy results were obtained in less than 5 working days. Patients were responsible for covering the cost of the kidney biopsy. The data collected were analyzed using Epi Info V7 software. We performed 120 kidney biopsies during the study period. The average age of the patients was 35 years ± 15.4 [5-68]. The male/female sex ratio was 2:1. Patients' medical history included herbal medicine use in 33% of cases and high blood pressure in 27.5% of cases. Proteinuria was present at a rate of ≥3 g/24 h in 46.6% of them. The primary indication for kidney biopsy was glomerular syndrome in 62.5% of cases, including 50% with nephrotic syndrome. All kidney biopsies were performed with real-time ultrasound guidance, using an automatic gun fitted with a 16G needle. Regarding complications, macroscopic hematuria was present in 12.5% of cases. Inadequate kidney biopsy was infrequent (5.8% of cases). The most common findings were (i) glomerular diseases (58.4%), such as membranoproliferative glomerulonephritis (13.3%), focal-segmental glomerulosclerosis (10.6%), lupus nephritis (8.8%), minimal change disease (8%), and membranous nephropathy (2.7%), and (ii) tubulointerstitial changes (31.8%). Diabetic nephropathy was rare (2.6%), as was IgA nephropathy (0.9%). We have demonstrated that implementing a sustainable kidney biopsy program in a very poor country is feasible, thanks to the dedication of a specialized renal pathologist. Having a clear diagnosis can assist in properly treating these renal patients according to international guidelines, thereby delaying the progression to end-stage kidney disease.
RESUMO
BACKGROUND: Kidney transplantation is the treatment of choice for end-stage chronic kidney disease. It improves quality of life and increases life expectancy. At present, Niger is one of the poorest countries in the world does not practice kidney transplantation; thus, patients continue to be referred to other countries for transplantation. METHODS: This descriptive cross-sectional study was carried out at the Nephrology Department of the National Hospital Amirou Boubacar Diallo in Niamey, Niger over a 5-month period. It included all patients that had benefited from kidney transplantation with the aim to evaluate patient and graft survival. RESULTS: We identified 25 patients. The male to female ratio was 2:1. The average age was 45.4 years ± 11.1 years. The average age of donors was 36.1 years ± 12.6 years with a clear male predominance (17 males to 8 females); all of them were related-donors with 72% of them being brothers or sisters. The causative nephropathy was undetermined in 80% of patients. Sixty-four percent of patients had their kidney transplant in Maghreb, including 16% in Tunisia. The complications were mostly medical (68%), as 20% were immunologic; 8% infectious; 16% metabolic; 20% cardiovascular, and 4% were related to recurrence of the initial nephropathy. Surgical complications involved 6 patients (24%): 5 were vascular cases and one was a urological case. With a median follow-up of 5 years, the patients' survival was 84%, the graft survival was 56%, and death-censored graft survival was 67%. CONCLUSION: In Niger, after kidney transplantation, the patients' survival is satisfactory, whereas the graft survival is not, mostly due to inadequate follow-up check-ups and prohibitive prices of immunosuppressants.

Despite positive economic forecasts, stable democracies, and reduced regional conflicts since the turn of the century, Africa continues to be afflicted by poverty, poor infrastructure, and a massive burden of communicable diseases such as HIV, malaria, tuberculosis, and diarrheal illnesses. With the rising prevalence of chronic kidney disease and kidney failure worldwide, these factors continue to hinder the ability to provide kidney care for millions of people on the continent. The International Society of Nephrology Global Kidney Health Atlas project was established to assess the global burden of kidney disease and measure global capacity for kidney replacement therapy (dialysis and kidney transplantation). The aim of this second iteration of the International Society of Nephrology Global Kidney Health Atlas was to evaluate the availability, accessibility, affordability, and quality of kidney care worldwide. We identified several gaps regarding kidney care in Africa, chief of which are (i) severe workforce limitations, especially in terms of the number of nephrologists; (ii) low government funding for kidney care; (iii) limited availability, accessibility, reporting, and quality of provided kidney replacement therapy; and (iv) weak national strategies and advocacy for kidney disease. We also identified that within Africa, the availability and accessibility to kidney replacement therapy vary significantly, with North African countries faring far better than sub-Sahara African countries. The evidence suggests an urgent need to increase the workforce and government funding for kidney care, collect adequate information on the burden of kidney disease from African countries, and develop and implement strategies to enhance disease prevention and control across the continent.
RESUMO
BACKGROUND: Pyelo-ureteral junction syndrome (PUJS) is a frequent congenital malformation. We report the surgical management of PUJS by pyeloplasty according to Anderson-Hyne-Kuss's procedure at the Zinder National Hospital.. METHODS: This was a retrospective study from January 2013 to December 2016 (4 years), including patients who have undergone surgery for PUJS. RESULTS: Twelve (12) cases of PUJS had a surgery among which 66.7% were men with an average age of 32.5 ± 7.6 years. The clinical symptomatology was lumbar pain or renal colic in 92.3% of cases. This pain had evolved for more than 2 years for 58.3% of the cases. Ultrasound coupled with intravenous urography or CT-scan was performed to confirm the diagnosis of PUJS in 58.3 and 41.7% of cases. The average serum creatinine level at admission was 181.25 ± 67.3 µmol/L [Lab reference range: 53-97 µmol/L]. The Anderson-Hynes non dismembered pyeloplasty is used for all the patients. The release of a crossing lower pole vessel was performed in 25%, pyelolithotomy in 16.7%. The average surgery time was 118.3 ± 20.7 min. The average hospital length of stay was 10.8 ± 3 days. Immediate postoperative complications were recorded in 33.3% (n = 4). Postoperative outcomes were considered good by disappearance of clinical, biological and radiological signs. CONCLUSION: The Anderson-Hynes non dismembered pyeloplasty gives good results and provides a successful alternative in an environment where laparoscopy and robotic surgery are not developed.

This study decribes the treatment of a 37-year old female patient, with a history of poorly treated arterial hypertension (AH), referred to surgical consultation with right lower back pain, vertigo, headache, sweating and palpitations. During hospitalization, blood pressure (BP) ranged between 130/80 mm Hg and 190/120 mm Hg. The remainder of the clinical examination was normal. Thoracoabdominal scanner showed adrenal mass measuring 55x45x65 mm compressing the inferior vena cava and the right renal vein. The assay of urinary vanilmandelic acid (VMA) was 11.8mg/24hours. The assay of catecholamines in the blood was not performed. The diagnosis of pheochromocytoma was retained and surgical indication was determined. During pre-anaesthesia consultation, clinical examination showed good general condition, blood pressure (BP) to190/120 mmHg, normal cardiopulmonary auscultation and prediction criterion of easy intubation (Mallampati II). The patient underwent preoperative treatment with alpha-blockers and beta-blockers, and calcium channel blocker. Adrenalectomy was performed using midline laparotomy. The patient didn?t have hemodynamic instability during mobilization and tumor resection. The postoperative course was uneventful. She was discharged home on postoperative day 7. At 3 months? follow-up, the patient had no clinical signs and blood pressure was normal. Anesthesia for the surgical treatment of pheochromocytoma is feasible even in resource-limited settings. An adequate preoperative preparation of the patient helps prevent complications.
