Introduction: The frequent late-stage diagnosis of chronic kidney disease (CKD) constrains the treatment choices for nephrologists. Renal biopsy (RB) is crucial for accurately identifying renal lesions. This key nephrological procedure, however, is invasive and not without potential complications. The purpose of this study was to evaluate the indications, frequency, and histological lesion profiles of renal biopsies in Togo. Materials and Methods: We conducted a descriptive cross-sectional study encompassing all renal biopsies performed in Togo from the inception of nephrology services to the present. Data were compiled from the medical records of the patients. Results: From 2015 to 2023, 68 high-quality renal biopsies were executed in Togo. The patients had an average age of 30.6 years, with a predominance of males (69.1%). The most common indication was nephrotic syndrome, accounting for 66.2% of cases. Histologically, glomerulopathies were predominant, representing 61.8% of lesions, followed by vascular nephropathies (25%) and tubulointerstitial nephropathies (13.2%). The most frequently observed primary glomerulopathy was focal segmental glomerulosclerosis (FSGS). Gross hematuria was the sole complication, occurring in 1.4% of the cases. Conclusion: RB is an evolving practice in Togo. Glomerulopathies are the most commonly observed lesions. The histological categorization of renal lesions is vital for clinicians in their diagnostic reasoning and approach.

Objective: To describe the epidemiological, clinical and evolutionary profile of ADPKD in Togo. Methods: A retrospective descriptive transversal study over a period of 8 years (2011-2018) which focused on the analysis of patients’ records diagnosed with ADPKD. The diagnosis of ADPKD was retained on the basis of the ultrasound criteria of PEI. Results: During the study period, 27 patients had polycystic kidney disease with a prevalence of 0.87%. The average age was 51.6 ± 16.4 years. There were 10 men (37%) and 17 women (63%), a sex ratio (M/F) of 0.58. The concept of family cystic kidney disease was found in 6 (22.2%) patients. The clinical presentations were dominated by arterial high blood pressure, abdominal pain and abdominal mass respectively in 77%, 63% and 63% of cases. Five patients (18.5%) had a glomerular filtration rate (GFR) greater than 90 ml/min, 17 (62.9%) had a GFR Conclusion: ADPKD is common in our department. It appears to be associated with a high rate of chronic renal failure.

Context: Acute kidney injury (AKI) in intensive care unit (ICU) is common and associated with very high mortality. In Togo, a tropical country with limited resources and only one nephrology department in the north, acute kidney injury seems to be a real tragedy with high mortality. Aims: to determine risk factors for mortality in acute kidney injury in the intensive care units. Methods and Material: We made a multicentric cross sectional study during 6 months in the four referral centers in northern Togo. Univariate and multivariate logistic regression was used to identify factors associated with mortality. Data were analyzed using RStudio 2023.04.1. Results: A total of 12.6% of patients admitted to intensive care had presented with AKI. The mean age was 49.6 ± 17.9. The sex ratio (M/F) was 2.1. Community-acquired AKI was in the majority (67.7%). Oligo anuria was the most frequent functional sign (38.4%). In our series, 81.6% of patients were in KDIGO stages 2 to 3. AKI was organic in 56.2% of cases. Mortality was 44.3%. In multivariate analysis, the main factors predictive of death were: respiratory distress (OR = 2.36;p Conclusions: Acute kidney injury in intensive care is common in northern Togo, and mortality is high. Identification of associated factors should help anticipate prognosis.

Background: Angiotensin-converting enzyme 2 has been identified as the receptor that allows the entry of SarsCov2 into the human cell. Its expression in the kidney is 100 times higher than in the lung;thus, making the kidney an excellent target for SarsCov2 infection manifesting as renal failure (RF). The objective of this study was to determine the predictive factors of RF during COVID-19 in the Togolese context. Patients and Methods: This was a retrospective descriptive and analytical study conducted at the Lomé Anti-COVID Center including the records of patients hospitalized for COVID-19, of age ≥ 18 years and having performed a creatinemia. RF was defined by a GFR 2 calculated according to the MDRD formula. Patients were randomized into 2 groups according to GFRResults: 482 patients were selected for this study with a mean age of 58.02 years. Sixty-five percent of the patients were men, i.e., a sex ratio of 1.88. Fifty-two patients had RF, i.e., a frequency of 10.8%.There were 65% men (315 cases), for a sex ratio (M/F) of 1.88. Risk factors for renal failure in COVID-19 were age ≥ 65 years (ORa 2.42;CIa95% [1.17 - 4.95];p = 0.016), anemia (ORa 2.49;CIa95% [1.21 - 5.26];p = 0.015), moderate (ORa 13;CIa95% [2.30 - 2.44];p = 0.017), severe (ORa 26.2;CIa95% [4.85 - 4.93];p = 0.002) and critical (ORa 108;CIa95% [16.5 - 21.76];p Conclusion: Renal failure would therefore be related to the severity of COVID-19 and is the most formidable factor, conditioning the course of the disease and the patient’s vital prognosis.

Introduction: In haemodialysis patients, the risk of acquiring blood-borne viral infections is an important cause of the dialysis’s process. Indeed, viral infections are quite common in chronic haemodialysis patients including those due to viral hepatitis B and HIV. Objective: Determine the prevalence of HIV infection and hepatitis B infection among chronic hemodialysis patients of Togo. Methods: A cross-sectional study was conducted in chronic hemodialysis patients of Togo from January 1st to December 31st, 2016. Sociodemographic and clinical data were collected. Antigen HBs was screened by a rapid immunochromatographic test (SD BIOLINE? HBsAg), and HIV antibodies were detected using a combination of 2 rapid diagnostic test, SD BIOLINE? HIV-1/2 (first step) and TRIDOT test (second step). Results: During the study period, 95 subjects were included. Patient’s age was ranking from 13 to 80 years with a mean of 46.6 years. The sex-ratio (M/F) was 1.8 and a duration average of dialysis was 51.7 months. The aetiologies of the chronic endstage kidney failure were related respectively to a vascular renal disease for 42.1% of the patients, glomerular nephropaty for 34.74%, interstitial nephropaty for 9.47% and hereditary for 3.16%. For 10.53% of the patients, the initial renal disease remained indefinite. Prevalence of antigen HBs and HIV antibodies were respectively 10.5% and 7.4%. The frequency of co-infection HBV and HIV was 1.1%. Conclusion: The rates of HBV infection and HIV infection remain high in chronic hemodialysis in Togo, somewhat which is linked to an endemic aspect of these two viruses in the country. The type of initial renal disease (glomerular) and the vascular way (the central catheters) established the risk factors for the HIV infection while for the infection of HVB no factor was incriminated.

HIV infection is a major cause of chronic kidney disease, associated with high morbidity and mortality in sub-Saharan Africa. The objective of this study is to assess the prevalence and risk factors of renal disease at initiation of antiretroviral therapy. This was a descriptive and analytical retrospective study carried out in the infectious and tropical diseases department at Sylvanus Olympio University Hospital. The data have been extracted from the ESOPE software. Kidney disease was defined by a GFR, estimated by MDRD (Modification of Diet in Renal Disease) formula, less than 60 ml/min/1.73 m2. Risk factors associated with kidney disease were assessed using univariate and multivariate analysis. There were 3118 HIV-infected patients included in our study. The median estimated filtration rate was 94.7 ml/min/1.73 m2: 2.9% had an eGFR 2. 1303 had kidney disease (41.8%). Most patients (30.8%) were in the WHO clinical stage 1. The median CD4 count was 165/μL [IQR = 72 - 274/μL];the median hemoglobin level was 10.4 g/dL [IQR = 8.8 - 11.9 g/dL];all patients had thrombocytopenia less than 100.000/mm3;8.5% had leukocytosis greater than 10.000/mm3. Most of patients had HIV1. In the multivariate analysis, age greater than 40 years (p 3 were significantly associated with renal disease. The prevention of kidney disease must go through the identification of its risk factors in the target populations.
