Sepsis is one of the commonest problems associated with the admission of critically ill patients, especially HIV/AIDS
patients at the Critical Care Units of Hospitals. Diagnosis and prognosis of sepsis in the clinical setting is a challenge
since there is no diagnostic tool for measuring the severity and course of sepsis. Therefore, this study was designed to
assess the use of Procalcitonin as a surrogate marker of sepsis in a case-control study of both septic and non-septic
HIV/AIDS and also for the determination of its cut-off threshold for sepsis.
Using a hospital-based case–control study design, 100 HIV/AIDS patients comprising of 66 septic cases and 34 nonseptic
were recruited from the Emergency Department of Komfo Anokye Teaching Hospital (KATH), Ghana. Sepsis
was defined using the Systemic inflammatory response syndrome (SIRS) criteria. Serum Procalcitonin (PCT) and Creactive
protein (CRP) levels were measured by standard ELISA principle.
Prevalence of the overall sepsis, was assessed at 60. 5% among patients who were on Anti-retroviral therapy (ART),
66. 7% in females and 33. 3% in males. Viral suppression was 71% in septic patients. The overall mortality rate
recorded was 89. 4%. ART however, did not confer protection from death, as 56. 5% of cases on ART died.
Only 22. 7% of the septic patients produced positive blood cultures. PCT was significantly higher in septic patients
than in non-septic patients (p=0. 000) and also higher in patients with positive blood cultures as compared with
negative blood cultures (p=0. 001). PCT levels were significantly high in patients who died as compared to those who
survived (p=0. 000). The AUC of PCT and CRP were 0. 968 and 0. 726 at cut-offs of 0. 496 ng/ml and 39. 281
mg/L respectively for diagnosing sepsis in HIV/AIDS patients. The study clearly shows that PCT is a better surrogate
marker for diagnosing sepsis in people living with HIV/AIDS as compared to CRP.
