Epidemiological, clinical, therapeutic features and predictors of death among COVID-19 patients hospitalized in Parakou: a cross-sectional study in Northern Benin.

BACKGROUND: COVID-19 is an emerging contagious infection with polymorphic clinical manifestations. The purpose of this study was to describe the epidemiological, clinical, therapeutic features and identify the predictors of mortality among COVID-19 hospitalized cases in Parakou. METHODS: This was a cross-sectional, descriptive and analytic study. Systematic recruitment was used to include all patients hospitalized with COVID-19 from May 8, 2020, to December 31, 2021, whose medical records were available and usable. The variables studied were clinical and paraclinical signs, diagnostic and therapeutic means, evolution under treatment and prognostic factors. This study was approved by the Local Ethical Committee. The data were analyzed using Stata/MP 14.1 software. RESULTS: A total of 198 cases of COVID-19 were identified, 117 of whom were men. The mean age was 51.53 ± 19.51 years. The presenting signs were fever 146 (74.11%), cough 157 (79.70%) and dyspnea 118 (53.90%). It was severe COVID-19 in 108 cases (54.55%). Therapeutically, 95 patients (47.98%) had received the combination of Lopinavir/ritonavir and Ribavirin and 95 others (47.98%) received chloroquine. Recovery was noted in 151 (76.26%) patients. Mortality rate was 18.18%. Predictors of death were high blood pressure, presence of signs of severity, high-concentration mask ventilation used, and elevated transaminases. CONCLUSION: COVID-19 was a reality in Parakou, with a significant number of severe cases requiring hospitalization. Several factors are associated with the prognosis of the disease.

Acute kidney failure following severe viper envenomation: clinical, biological and ultrasonographic aspects.

BACKGROUND: Acute kidney injury (AKI) is a frequent complication of snakebite envenomation, which is still little known in sub-Saharan Africa. This study aims to describe the clinical, biological and ultrasonographic aspects of AKI following severe snakebite envenomation managed in the intensive care unit. METHOD: A prospective observational survey was performed in Benin over a period of 18 months. All patients suffering severe snakebite envenomation (SBE) were included. The diagnosis of AKI was made using the KDIGO criteria. Kidney ultrasound exam was performed in all patients to assess internal bleeding and morphological and structural abnormalities of the kidneys. RESULTS: Fifty-one cases of severe SBE were included. All patients presented inflammatory syndrome and showed abnormal WBCT whereas bleeding was found in 46 of them (90%). The median time to hospital presentation was three days. The majority of patients were male (M/F sex ratio = 1.55) and the median age was 26. Sixteen patients (31%) showed AKI according to the KDIGO criteria. Severe AKI (KDIGO stage 2 and 3) was observed in three patients, including one stage 2 and two stage 3. Kidney ultrasound revealed three cases of kidney capsular hematoma (6%), two cases of kidney hypertrophy (3%), three cases of kidney injury (4%), two stage 1 KDIGO and one stage 2 KDIGO. Only one patient benefited from hemodialysis. All patients showing AKI recovered without sequels. The median duration of hospital stays was four days. Seven patients died (14%) including four among the 16 AKI patients. Antivenom has been administered to 41 patients (80%). The comparison between patients without and with AKI did not show any significant difference except gender (p = 10-2). CONCLUSION: AKI is a common complication of severe snakebite envenomation. Resulting from inflammatory and hemorrhagic disorders, AKI may prove to be a short-term life-threatening factor.
