Renal biopsy is an invasive procedure used to evaluate the activity and the therapeutic management of kidney disease and kidney transplantation. Objective: The aim of this study was to describe the epidemiological, clinical, and pathological features of kidney disease diagnosed by biopsy in the Ivory Coast. Materials and Methods: This was a descriptive and prospective study conducted between January 2015 and December 2018 in the Department of Anatomy and Cytology of the Pathology of Cocody (Abidjan) and Bouake. Specimens were obtained from the nephrology department of Ivory Coast and from teaching hospitals in Togo, Guinea, Burkina Faso, and Mali. Samples were analyzed according to standard renal biopsy procedures. One kidney fragment was fixed in acetic acid formalin (AAF) for optical microscopy examination. The other fragment, soaked in physiological water, was immediately sent for immunofluorescence examination. All renal pathologies were included in this study. The study parameters were frequency, age, sex, origin, occupation, clinical and biological signs, and pathological aspects with optical microscopy, and immunofluorescence. Results: 153 cases (2.23%) of kidney biopsies were examined on a total of 10,573 specimens. Ivory Coast specimens accounted for 91.5% of cases (n = 140). nephrotic syndrome (49%) was the most common clinical sign and indication for renal biopsy, followed by acute renal failure (16.3%), chronic renal failure (19.6%), and a combination of chronic renal failure with hypertension (11.18%) and glomerulonephritis (4%). Mean proteinuria was 3.03 g/24h (ran.e, 0.14 to 11.5 g/24h). Histologically, 90.8% (n = 139) were glomerular nephropathies, including 26.6% HIV-associated nephropathy, 17.3% focal segmental glomerulosclerosis, 13.6% nephroangiosclerosis, 11.5% post-infectious glomerulonephritis, 9.3% membranous glomerulonephritis, and 21.6% miscellaneous glomerular nephropathies (n = 30). The incidence of various tubulo-interstitial lesions was

Focal segmental glomerulosclerosis (FSGS) is characterized histologically by hyalinosis and sclerosis of glomeruli associated or not with podocyte involvement. The objective of our work was to clarify the epidemiological aspects and histological variants of FSGS in Côte d’Ivoire. Materials and Methods: This was a descriptive retrospective study, conducted from January 2015 to December 2019 using the renal biopsy registers (RB) of the Pathological Anatomy and Cytology departments of the Teaching Hospital of Cocody and Bouake in collaboration with the nephrology Services of Côte d'Ivoire and the sub-region. The biopsies underwent conventional histopathology and/or immunofluorescence techniques. The parameters analyzed were: frequency, age, gender, proteinuria, biopsy indications and histological aspects and the different correlations between histological aspects and socio-demographic characteristics. Results: FSGS represented 58.1% (n = 104) of glomerular nephropathies. The average age of patients was 32.1 ± 13.3 years, with extremes of 13 and 70 years. The sex ratio was equal to 1. nephrotic syndrome (68.9%), chronic renal failure (14.3%) and acute renal failure (10.1%) were the main indications for renal biopsy (RB). The mean proteinuria at the time of diagnosis was 4 ± 3.7 g/24 h. It was massive (3.5 g/24 h) in 42.3% of patients. FSGS was primary in 29.8% (n = 31) and secondary in 70.2% (n = 73) of patients, of which 27.9% (n = 35) was due to HIV. According to the Columbia classification, 62.5% nOS type was found;23.1% collapsing type;7.7% tip lesion type;4.8% cell type and 1.9% perihilary type. Conclusion: FSGS is a complex heterogeneous entity. It affects young people in our context with a homogeneous gender distribution. Understanding its histogenesis is essential for optimal patient management.
