A rare presentation of transient hypothermia in HIV infection: A case report and systematic review of cases

Hypothermia defined as a core body temperature less than 35°C causes hundreds of deaths annually in the United States. It can occur in a variety of clinical settings, including environmental exposure, shock, infection, metabolic disorders, alcohol, or drug toxicity, and malnutrition. This condition can affect many different organ systems and may lead to serious complications including cardiac arrhythmia. Hypothermia is extremely rare in people living with HIV but can be seen in severely malnourished patients or those who are not receiving antiretroviral therapy (ART). It is a life-threatening situation that should be treated aggressively. To the best of our knowledge, there are only a few cases that have been reported for people living with HIV presenting with hypothermia and sinus bradycardia. Herein, we are reporting a very rare case of people living with AIDS who presented with hypothermia complicated by sinus bradycardia. In addition, we also performed a systematic review of cases based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline, to investigate the clinical characteristics and outcomes associated with this rare complication. This systematic review of cases hopefully can increase the awareness of this rare entity and help improve its outcome.
