Acute Kidney Injury (AKI) in the Setting of Multi-Organ Dysfunction Syndrome (MODS) Secondary to Yellow Fever Infection (YFI) in a 19-Year-Old Woman

摘要

Background: Outbreak of yellow fever infection (YFI), a mosquito-borne disease, occurs sporadically worldwide especially in tropical nations. 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. Aim: 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). Case Presentation: 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. Conclusion: 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.
