Abstract
- Cilj ovog istraživanja bio je odrediti heterogenost podtipova HIV-a te analizirati primarnu rezistenciju virusa na antiretrovirusne lijekove u 30 prethodno neliječenih osoba koje su uključene u kliničku skrb Referentnog centra za dijagnostiku i liječenje HIV/AIDS-a tijekom 2013. g. Sekvenciranjem pol gena HIV-a te primjenom bioinformatičkih algoritama određeni su podtipovi virusa te detektirane mutacije povezane s primarnom rezistencijom na antiretrovirusne lijekove. Većina ispitanika (86,7%) bila je zaražena podtipom B. Otkriveno je 12 mutacija povezanih s primarnom rezistencijom HIV-a na antiretrovirusne lijekove, tj. 9 mutacija povezanih s primarnom rezistencijom na nukleozidne analoge inhibitore reverzne transkriptaze (NRTI) te 3 mutacije povezane s rezistencijom na nenukleozidne inihibitore reverzne transkriptaze (NNRTI). Primarna rezistencija na dvije klase antiretrovirusnih lijekova (NRTI i NNRTI) otkrivena je u jednog ispitanika. Najzastupljenija mutacija povezana s primarnom rezistencijom virusa na lijekove bila je T215S (rezistencija na NRTI). Mutacije značajne za nastanak primarne rezistencije detektirane su u 4 osobe zaražene podtipom B, jedne osobe zaražene podtipom A1 te jedne osobe zaražene rekombinantom podtipova A1 i B. U ovom je istraživanju po prvi puta dokazana pojava primarne rezistencije HIV-a na antiretrovirusne lijekove u osoba zaraženih non-B podtipovima virusa iz Hrvatske.<br />The aim of this study was to analyse HIV subtype diversity as well as primary resistance to antiretroviral drugs in 30 treatment-naive individuals entering clinical care at the National Refence Center for HIV/AIDS during 2013. Sequencing the pol region of the viral genome and bioinformatic algorithms were used to determine HIV subtypes and to analyse transmitted drug resistance mutations. The majority of individuals (86,7 %) were infected with HIV-1 subtype B. Twelve mutations associated with primary resistance to antiretroviral drugs were detected in the study: 9 mutations conferring resistance to NRTI (nucleotide reverse-transcriptase inhibitors) and 3 mutations associated with resistance to NNRTI (non-nucleotide reverse-transcriptase inhibitors). Primary resistance to two antiretroviral drug classes (NRTI and NNRTI) were detected in one individual. The most frequent mutation was T1215S associated with primary resistance to NRTI. Drug resistance mutations were detected in 4 subtype B and 2 non-B HIV-infected individuals. This study showed, for the first time, the presence of mutations associated with primary resistance of HIV to antiretroviral drugs in individuals infected with non-B subtypes in Croatia.
