The toxic origin is avoidable. Our objectives were to determine the toxic substances at the origin of ATN at the Brazzaville University Hospital and determine the evolving aspects and the factors associated with it. Patients and Methods: We carried out a 12-month from June 20, 2022 to June 30, 2023. It was a prospective observational study in the Nephrology Department of Brazzaville University Hospital Center. The diagnosis of ATN was done in the presence of AKI occurring in the context of taking nephrotoxic substances with negative albuminuria. Cases of ATN aggravating CKD were excluded. Data analysis was done with Epi-Info 7.2 software. Results: We identified 63 cases of AKI on toxic ATN. Their average age was 47 ± 19 years with a male predominance of 60.2%. The 3 main toxicants incriminated were: herbal medicine (49.2%), Gentamycin (17.5%) and non-steroidal anti-inflammatory drugs (14.3%). An indication for hemodialysis was made in 43 patients (68.2%), the evolution was marked by a cure in 29 patients (46.1%), 10 (15.9%) became chronic kidney failure, 19 (30.1%) died, 5 (7.9%) were lost to follow-up. The main factor for non-healing is anuria (p Conclusion: The main cause of toxic ATN at Brazzaville University Hospital is herbal medicine. The death rate is high there.展开更多

This comprehensive review article provides an in-depth examination of the risk elements, etiology, diagnosis, management, and preventive approach of AKI. The causes that contribute to the development of AKI include prerenal, intrinsic renal, and postrenal. The diagnostic approach to AKI includes clinical, laboratory, and imaging studies to evaluate the root cause analysis and to find out the severity of kidney injury. Timely and accurate diagnosis is crucial for initiating appropriate management strategies. The treatment strategies may include fluid and electrolyte management, medication adjustments, nutritional support, and renal replacement therapy. The prospect of recovery diverges as it relies on the individual factors, reasons, and gravity of the condition. This review highlights the importance of raising awareness among healthcare professionals and the public about AKI, early recognition of risk factors, and prompt management. Further research is needed to explore novel therapeutic approaches and refine existing management guidelines for this critical condition.展开更多

Acute kidney injury (AKI) commonly results from YFI and could be associated with a poor prognosis for victims even under intensive care unit (ICU). Pathophysiologic mechanisms for AKI include hypovolemic shut down, cytotoxicity, acute tubular necrosis (ATN), hemolysis, or coagulopathy. Early diagnosis, prompt and effective treatment modalities including dialysis improve treatment outcome. <strong>Aim: </strong>We report the case management of a 19-year-old woman who had yellow fever infection complicated by acute kidney injury in the setting of multi-organ dysfunction syndrome (MODS). <strong>Case Presentation: </strong>A 19-year-old woman who presented with fever, headache and vomiting for 2 weeks. In the course of the illness, urine volume became reduced and coke colored, followed by body swelling, yellowness of the eyes bleeding from the orifices. Examination revealed an acutely ill looking woman, icteric, and with pedal edema. Her pulse was 100/min and blood pressure was 120/80 mmHg. Liver was enlarged, soft and tender. She had proteinuria 3+ and polymerase chain reaction (PCR) confirmed yellow fever infection. She had markedly deranged serum biochemical parameters for which she had a three-hour session of hemodialysis with Heparin anticoagulation. The urea reduction ratio (URR) was 46.9%. Barrier nursing was commenced. She had 7 units of whole blood and a pint of fresh frozen plasma (FFP) with antibiotics, Rabeprazole, Tranexamic acid, Vitamin K and Frusemide. She had the second dialysis session of HD and entered into the recovering phase of AKI and was subsequently discharged after 18th days on admission. <strong>Conclusion: </strong>Yellow fever infection occurs sporadically and could lead to MODS involving the kidneys, liver and hematologic system. Prompt initiation of dialysis, correction of coagulopathy, and antibiotics use are measures needed to arrest progression and death. Vaccination, destruction of the natural habitat of the carrier and infective organisms are necessary particularly in endemic regions of the world.展开更多
