ABSTRACT
Human T-lymphotropic virus-I/II (HTLV-I/II) and human immun viruses (HIVs), that have similar genomic characteristics also share the same transmission routes and infect T lymphocytes. Regarding this epidemiological similarity, HIV and HTLV infections can be seen together. HIV and HTLV-I/II coinfection occurs with variable frequencies in different populations and geographic regions. There are not any population-based studies carried out defining the number of individuals coinfected with HIV and HTLV-I/II in Turkey. The aim of this study was to determine the seropositivity rates of HTLV-I/II in patients whose HIV viral load was monitored in Gazi University Faculty of Medicine Medical Virology Laboratory Forty-seven HIV positive cases followed-up in Medical Virology Laboratory for HIV viral load monitoring between May 2017-January 2019 were included in the study. HIV seropositivity of the samples was confirmed by the chemiluminescence microparticle immunoassay method. HIV viral load values of the samples were evaluated by real-time reverse transcriptase polymerase chain reaction. The samples were screened for antibodies against HTLV-I/II using chemiluminescent microparticle immunoassay. The study population range was between 19 to 60 years of age. Among the study population, 39 (83%) patients were male and 8 (17%) patients were female. Of 47 samples, 18 samples (38.3%) had viral load of <1000 copies/ml, 10 samples (21.3%) had viral load of 1000-10000 copies/ml, 19 samples (40.4%) had viral load of ≥10000 copies/ml. HTLV serology was negative in all samples included in the study. CD4+ results were available for 42 patients and the CD4+ results of five patients could not be studied. Co-infection with different retroviruses is a well-known fact which should be thoroughly examined. HTLV-I co-infection leads to faster progression of the disease in HIV-1 positive patients. Although it is known that the co-infection has a significant effect on the progression of the disease, there are very few centers in the world and in our country that routinely perform HTLV testing in HIV-positive patients. We think that in order to evaluate the clinical and microbiological importance of the coinfection of retroviruses with each other and to determine the frequency of these infections together, there is a need for studies involving a larger number of patients, including detailed clinical backgrounds of individuals, and that the importance of this issue should be realized at the same time.
