Predictive Factors of Renal Failure in COVID-19 Patients at the Anti-COVID Center in Lome, Togo

引用

Open Journal of nephrology 2024年第2期14卷 125-135页

作者： Kossi Akomola Sabi Yoan Makafui Amekoudi Awéréou Kotosso Laune Odilon Blatome Badomta Dolaama Ayodélé Jonathan Sabi Oscar Gnirimi Gbahbang Loutou Ahoub-Laye Affo Béfa Noto-Kadou-Kaza nephrology-Hemodialysis Department of CHU Sylvanus Olympio University of Lom Lom Togo Faculty of Health Sciences University of Lom Lom Togo nephrology Department of the CHU Kara University of Kara Kara Togo centre Hospitalier Universitaire Pointe--Pitre Pointe--Pitre Guadeloup

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.
