RESUMEN
BACKGROUND: Acute kidney injury (AKI) is an under-recognized disorder, which is associated with a high risk for mortality, development of chronic kidney disease (CKD). OBJECTIVE: We sought to describe and compare the causes and outcomes of AKI amongst adult patients in Douala general hospital (DGH) and Buea regional hospital (BRH). METHODS: A hospital-based retrospective cohort analytic study was carried from February to April 2021. Convenience sampling was used. We included Patient's files admitted from January 2016 to December 2020 aged > 18 years, with AKI diagnosed by a nephrologist and recorded values of serum creatinine (sCr) on admission and discharge. Data were analysed using SPSSv26. Chi-square, fisher, median mood's and regression logistic test were used, values were considered significant at p < 0.05. RESULTS: Of the 349 files included 217 was from DGH and 132 from BRH. Community acquired AKI were more present in BRH 87.12% (n = 115) than DGH 84.79% (n = 184) (p = 0.001). Stage III AKI was the most common presentation in both hospital. Pre-renal AKI was more common (p = 0.013) in DGH (65.44%, n = 142) than BRH (46.97%, n = 62). Sepsis and volume depletion were more prevalent in urban area with (64.51 and 30.41% vs. 46.21 and 25.75%) while severe malaria was more present in Semi-urban area (8.33% vs. 1.84%, p = 0.011). Complete and partial renal recovery was 64.97% (n = 141) in DGH and 69.69% (n = 92) in BRH (p = 0.061). More patients had dialysis in BRH 73.07% (n = 57) than in DGH 23.33% (n = 21). More patient died in DGH 33.18% (n = 72) died than in BRH 19.70% (n = 26) (p = 0.007). Stage III was significantly associated with non-renal recovery in both DGH (p = 0.036) and BRH (p = 0.009) while acute tubular necrosis was associated with non-renal outcome in DGH (p = 0.037). CONCLUSIONS: AKI was mainly due to sepsis, volume depletion and nephrotoxicity. Complete and partial recovery of kidney function were high in both settings. Patient outcome was poorer in DGH.

BACKGROUND: Late presentation (LP) of chronic kidney disease (CKD) patients to nephrologist is a serious problem worldwide with persistent high prevalence despite known benefits of early nephrology care. OBJECTIVE: Determine the prevalence and factors associated with LP of CKD patients to nephrologists in Cameroon. METHODS: A cross-sectional study from October 2015 to May 2016 at the nephrology units of the Douala General and Laquintinie hospitals, including all consenting incident CKD patients. Data collected were: socio-demographic, search of CKD diagnostic criteria during prior follow up, therapeutic itinerary, clinical and biological parameters at presentation, knowledge on CKD and attitude towards dialysis. LP was defined as eGFR < 30 ml/min/1.73 m2. It was physician-related whenever no CKD screening was done in the presence of risk factor or no referral to nephrologists at early stages; patient-related whenever patients did not have recourse to hospital care while symptomatic or disrespected a referral decision. p value <.05. RESULTS: We included 130 patients, mean age 53.10 ± 14.66 years, 60.77% males, 58.70% were referred by internal medicine physicians and 10% had recourse to complementary and alternative medicine (CAM). At presentation, 70.80% were symptomatic, 53% had CKD stage five, 86.12% were poorly graded on knowledge and 49% had a negative attitude towards dialysis. The prevalence of LP was 73.90%, 50% was physician-related, 44.79% patient-related and 5.21% both. Being accompanied (p = .038), a low level of education (p = .025) and recourse to CAM (p = .008) were associated with LP. CONCLUSION: LP is high in Cameroon, attributed to physician's practical attitudes and patient's socio-cultural behaviors and economic conditions.

INTRODUCTION: Chronic kidney disease (CKD) is frequent amongst human immunodeficiency virus (HIV)-positive patients, and screening is not routinely performed in Sub-Saharan Africa due to resource constraints. We aimed to determine the prevalence of CKD and associated factors in HIV-infected patients in Cameroon. MATERIALS AND METHODS: A cross-sectional study in Northern Cameroon included HIV-positive patients who attended the HIV clinic. Patients with an estimated glomerular filtration rate less than 60 mL/min/1.73 m² or urinary abnormalities underwent a second measurement 3 months later. Glomerular filtration rate was estimated using the 4-variable Modification of Diet in Renal Disease (MDRD) and the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations. Logistic regression was used to identify factors associated with CKD. RESULTS: We included 709 participants. The median CD4 count was 219 cells/mL. Proteinuria accounted for 34.4%; leukocyturia, 6.9%; and hematuria, 6.1%. Prevalence of CKD was 44.4% (CKD-EPI) and 47.2% (MDRD). Stages 3 to 5 of CKD were documented in 11.6% using the CKD-EPI and 7.5% using the MDRD. Factors associated with CKD were an age greater than 35 years (odds ratio [OR], 104; 95% confidence interval [CI], 1.02 to 1.06), longer duration of HIV (OR, 2.60; 95% CI, 1.53 to 3.95), history of hepatitis B (OR, 3.04; 95% CI, 1.08 to 8.54), and CD4 cells less than 200 cells/mL (OR, 3.64; 95% CI, 2.55 to 5.21). CONCLUSIONS: The prevalence of CKD is high among HIV patients in Cameroon. There is a need of implementing measures to encourage early detection of kidney disease in these patients.
