Sumario:BACKGROUND: Torque Teno Midi Virus/Small Anellovirus (TTMDV/SAV) is a member of the Gammatorquevirus genus within the family Anelloviridae. It is detected in healthy, Hepatitis B Virus, Hepatitis C Virus and HIV infected individuals and also patients with acute respiratory disease in different countries, but its role in clinical diseases and its full geographical distribution is still unclear. OBJECTIVES: The current study aimed to detect the frequency of infection with TTMDV/SAV in the sera of healthy blood donors, hepatitis C infected and HIV positive individuals in Lorestan province, Iran; and also investigate the possible role of TTMDV/SAV virus in liver diseases. MATERIALS AND METHODS: Fifty two, 36, 4, and 110 serum samples from HIV positive, patients with HIV/HCV and HIV/HCV/HBV co-infections, and healthy individuals were collected in Khorramabad city, respectively. Nested-polymerase chain reaction was performed using SMAs/SMAr primers to detect TTMDV/SAV DNA. Serum aminotransferases were measured. RESULTS: In the HIV/HCV, HIV/HCV/HBV, HIV, and control cases, 29 (80.5%), 3 (75%), 43 (82.7%), and 16 (14.5%) were positive for DNA of TTMDV/SAV, respectively. In the HIV/HCV infected cases and HIV positive cases the level of Alanine aminotransferase (ALT) and Aspartate aminotransferase (AST) were not significantly different in TTMDV/SAV infected and non-infected individuals (P > 0.05). CONCLUSIONS: Although significant differences (P < 0.01) were observed in the frequency of TTMDV/SAV between healthy controls and each of the HIV positive and HIV/HCV co-infected individuals, no significant difference was observed between HIV positive and HIV/HCV co-infected cases, which may be due to HIV associated immunodeficiency. This is the first time that TTMDV/SAV is reported in HIV infected individuals worldwide. Interpretation of the high frequency of the virus (82.7%) in HIV cases needs more detailed studies.
