Acute Human Immunodeficiency Virus (HIV) Infection Presenting with Fever, Elevated Amylase/Lipase, and Hematologic Abnormalities

AbstractBackgroundMany cases of acute human immunodeficiency virus (HIV) infection (AHI) present to the Emergency Department (ED). Early diagnosis allows a patient to modify their behavior and seek early treatment. The Emergency Physician should know that the antibody response may be absent.ObjectiveWe report a case of AHI and review its presentation to increase the awareness of this important diagnosis.Case ReportA 20-year-old black man who had a history of sex with men initially presented to the ED with a chief complaint of blood per rectum when he passed stool, and chills for the prior few days. His work-up was normal, including a rapid HIV screen, and he was discharged. He returned 2 weeks later with constipation, fatigue, myalgias, decreased urination, chills, and a productive cough. His physical examination was unremarkable, HIV antibody test was negative, but his laboratory tests showed an elevation of creatine phosphokinase, amylase, and lipase. His blood count showed a normal hematocrit and white blood cell count, but there were juvenile and vacuolated white cells and giant platelets reported. HIV viral load was reported as > 1,000,000 copies/mL.Conclusions/SummaryThis case illustrates that AHI can present as a non-specific illness. Patients at risk should be screened for HIV. However, AHI can occur before there is a significant antibody response. In such cases, a viral load test may help make the diagnosis, allowing for early treatment and patient counseling
