Coexistence of Competing Opportunistic Pathogens in Critically ill Patients with Advanced AIDS: A Case Report and Literature Review

Abstract

Introduction: Opportunistic infections (OIs) are the leading causes of morbidity and mortality among HIV-infected individuals. The incidence of OIs is greater in antiretroviral treatment (ART) naive patients. As of 30 June 2021, 28.2 (73%) people with HIV/AIDS (PLWHA) were accessing antiretroviral therapy (ART) globally, leaving the remaining 27% PLWHA without ART at risk for OIs. Multiple opportunistic infections are caused due to the coexistence of competing opportunistic pathogens that confound clinical manifestations, investigative procedures, and management protocols. Case Presentation: In this report, we describe the case of a critically ill HIV female patient admitted to the ICU. The patient was diagnosed with multiple opportunistic infections and subsequently died after her illness progressed. Due to the paucity of information on the subject, we conducted a retrospective study of 1440 case records of HIV/AIDS critically ill patients to determine the incidence and spectrum of multiple opportunistic infections. We performed a review of the available medical literature relevant to the subject. Conclusion: Knowledge of such events would guide and enhance the physician's diagnostic and management strategies, especially in resource limited regions.
