Objective: It has been reported that carnitine deficiency is observed in various viral infections and in the follow-up of the prognosis of some diseases. In this cross-sectional study, we aimed to determine how carnitine ester derivatives change in HIV-positive patients. Materials and Methods: In this study, 25 HIV-infected patients who applied to Harran University Faculty of Medicine Education Research and Practice Hospital Infectious Diseases and Clinical Microbiology Outpatient Clinic and who did not receive any antiretroviral treatment, as well as 25 healthy volunteers were included in the study. Carnitine ester levels in serum samples were measured by Liquid Chromatography-Mass Spectrometry/Mass Spectrometry (LC-MS/MS) method (Shimadzu North America, Columbia, MD, USA). Results: While suberoylcarnitine (C8DC), myristoleylcarnitine (C14:1), tetradecadienoylcarnitine (C14:2), palmitoleylcarnitine (C16:1), and linoleylcarnitine (C18:2) levels in HIV(+) patients were quite low compared to the control group, tiglylcarnitine (C5:1) levels were high (p ≤ 0.05). In addition, C5:1 and C14:2 index parameters according to VIP score, and C5:1 and C14:1/C16 index parameters according to ROC analysis were determined as markers with high potential to distinguish HIV(+) patients from healthy volunteers. Conclusion: This study showed that levels of acylcarnitine derivatives might be altered in HIV(+) patients, and the results obtained may contribute to a better understanding of carnitine metabolism.
