Abstract
AIDS is a globalized infectious disease. In 2014, UNAIDS launched a global project of "90-90-90" to end the HIV epidemic by 2030. The second and third 90 require 90% of HIV-1 infected individuals receiving antiretroviral therapy (ART) and durable virological suppression. However, wide use of ART will greatly increase the emergence and spreading of HIV drug resistance and current HIV drug resistance test (DRT) assays in China are seriously lagging behind, hindering to achieve virological suppression. Therefore, recommending an appropriate HIV DRT method is critical for HIV routine surveillance and prevention in China. In this review, we summarized the current existing HIV drug resistance genotypic testing methods around the world and discussed the advantages and disadvantages of these methods.

Optimization of the oligonucleotide ligation assay for the detection of nevirapine resistance mutations in Zimbabwean Human Immunodeficiency Virus type-1 subtype C. J Virol Methods 2014; 210:36-9.

Abstract
An oligonucleotide ligation assay (OLA) designed to detect Human Immunodeficiency Virus type-1 (HIV)-drug-resistance to the nevirapine (NVP) selected mutations K103N, Y181C, V106M and G190A was used to evaluate 200 archived dried blood spots (DBS) from infected infants participating in the Zimbabwean Early Infant Diagnosis (EID) Program. Consensus sequencing of specimens with indeterminate OLA results was performed to identify genetic sequence polymorphisms that appeared to compromise performance of the OLA. When consistent patterns of polymorphisms were observed the probes were redesigned, and DBS specimens with indeterminate OLA results were retested with the new Zimbabwe-specific (ZW) probes. OLA results obtained in Zimbabwe were compared to repeat testing in a US reference laboratory. 188/200 (94%) DBS yielded polymerase chain reaction (PCR) amplification of HIV pol. ZW probes reduced indeterminate OLA results from 5.2% to 2.8% of codons evaluated (p=0.02), with 98.2% concordance between results obtained in the Zimbabwean and US laboratories. Optimization of OLA probes to accommodate polymorphisms in regional HIV variants improved OLA performance, and comparison to the USA results showed successful implementation of the OLA in Zimbabwe for detection of NVP resistance mutations in DBS specimens.

Improvement of the oligonucleotide ligation assay for detection of the M184V drug-resistant mutation in patients infected with human immunodeficiency virus type 1 subtype CRF01_AE. J Virol Methods 2013; 190:20-8. [PMID: 23562659 DOI: 10.1016/j.jviromet.2013.03.016] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2012] [Revised: 11/22/2012] [Accepted: 03/19/2013] [Indexed: 11/15/2022]
Abstract
Methods based on genetic sequencing to monitor drug-resistance mutations in human immunodeficiency virus type 1 (HIV-1) require expensive instruments and are only capable of detecting mutant strains comprising >20% of virus populations. The National Institutes of Health's AIDS Research and Reference Reagent Program (NIH ARRRP) makes available a probe-based method, an oligonucleotide ligation assay (OLA-ARRRP), which is less expensive and more sensitive than sequencing to detect such mutations for HIV-1 subtype B. In this study, an OLA was designed to detect the Methionine to Valine mutation at codon 184 (M184V) of the reverse transcriptase (RT) gene in the circulating recombinant form AE strain of HIV-1 (HIV-1 CRF01_AE) common in Thailand, and was evaluated in Thai patients experiencing treatment failure. The subtype-specific OLA-CRF01_AE proved superior to OLA-ARRRP in detecting M184V, although this mutation existed in the genome of the multiple-drug-resistant virus at lower minimal detection levels of 3% prevalence of mutated virus, compared to 50% for OLA-ARRRP. On evaluation using clinical specimens, OLA-CRF01_AE showed excellent agreement with nucleotide sequencing (95.1% overall concordance, kappa>0.79), and the sensitivity was 100% for wild-type and 93.9% for mutant detection at codon 184. The OLA-CRF01_AE also detected M184V mutations in 2.4% (1/42) of specimens that were not detected by sequencing. The indeterminate detection by OLA-CRF01_AE was decreased, from 16.7% to 4.8%, in the samples containing mutant genotype when the strategy using unmodified- as a substitute of the modified-mutant detector probe was applied. Because of their low cost, sensitivity, and ease of use, the OLA-CRF01_AE is an attractive alternative to standard sequencing in resource-limited countries affected by this subtype of HIV-1.

Abstract
Transmission of drug-resistant HIV (TDR) has been associated with virologic failure of "first-line," nonnucleoside reverse transcriptase inhibitor (NNRTI)-based antiretroviral therapy (ART). A national ART program began in Peru in 2004. We evaluated the prevalence of TDR in individuals initiating ART and their virologic outcome during 2 years of ART. HIV-infected, ARV-naive subjects who met criteria to start ART in Lima, Peru were enrolled in a longitudinal observational study between July 2007 and February 2009. Blood plasma and cells obtained prior to ART initiation were assessed for antiretroviral (ARV) resistance by an oligonucleotide ligation assay (OLA) sensitive to 2% mutant at reverse transcriptase (RT) codons K103N, Y181C, G190A, and M184V and a subset by consensus sequencing. A total of 112 participants were enrolled; the mean CD4 was 134 ± 89 cells/μl and the median plasma HIV RNA was 93,556 copies/ml (IQR 62,776-291,364). Drug resistance mutations conferring high-level resistance to ARV were rare, detected in one of 96 (1%) evaluable participants. This subject had the Y181C mutation detected in both plasma and peripheral blood mononuclear cells (PBMCs) at a concentration of 100% by OLA and consensus sequencing; nevertheless nevirapine-ART suppressed her viral replication. Consensus sequencing of 37 (19%) participants revealed multiple polymorphisms that occasionally have been associated with low-level reductions in ARV susceptibility. A low prevalence of TDR was detected among Peruvians initiating ART. Given the increasing availability of ART, continuing surveillance is needed to determine if TDR increases and the mutant codons associated with virologic failure.

Human immunodeficiency virus type 1 resistance or cross-resistance to nonnucleoside reverse transcriptase inhibitors currently under development as microbicides. Antimicrob Agents Chemother 2011; 55:1403-13. [PMID: 21282453 PMCID: PMC3067143 DOI: 10.1128/aac.01426-10] [Citation(s) in RCA: 23] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2010] [Revised: 11/29/2010] [Accepted: 01/19/2011] [Indexed: 11/20/2022] Open
Abstract
Microbicides based on nonnucleoside reverse transcriptase inhibitors (NNRTIs) are currently being developed to protect women from HIV acquisition through sexual contact. However, the large-scale introduction of these products raises two major concerns. First, when these microbicides are used by undiagnosed HIV-positive women, they could potentially select for viral resistance, which may compromise subsequent therapeutic options. Second, NNRTI-based microbicides that are inactive against NNRTI-resistant strains might promote the selective transmission of these viruses. In order to address these concerns, drug resistance was selected in vitro by the serial passage of three viral isolates from subtypes B and C and CRF02_AG (a circulating recombinant form) in activated peripheral blood mononuclear cells (PBMCs) under conditions of increasing concentrations of three NNRTIs (i.e., TMC120, UC781, and MIV-160) that are currently being developed as candidate microbicides. TMC120 and MIV-160 displayed a high genetic barrier to resistance development, whereas resistance to UC781 emerged rapidly, similarly to efavirenz and nevirapine. Phenotypically, the selected viruses appeared to be highly cross-resistant to current first-line therapeutic NNRTIs (i.e., delavirdine, nevirapine, and efavirenz), although they retained some susceptibility to the more recently developed NNRTIs lersivirine and etravirine. The ability of UC781, TMC120, and MIV-160 to inhibit the in vitro-selected NNRTI-resistant viruses was also limited, although residual activity could be observed for the candidate microbicide NNRTI MIV-170. Interestingly, only four p2/p7/p1/p6/PR/RT/INT recombinant NNRTI-resistant viruses (i.e., TMC120-resistant VI829, EFV-resistant VI829, MIV-160-resistant VI829, and EFV-resistant MP568) showed impairments in replicative fitness. Overall, these in vitro analyses demonstrate that due to potential cross-resistance, the large-scale introduction of single-NNRTI-based microbicides should be considered with caution.

Virological response to highly active antiretroviral therapy in patients infected with human immunodeficiency virus type 2 (HIV-2) and in patients dually infected with HIV-1 and HIV-2 in the Gambia and emergence of drug-resistant variants.

Abstract
Drug design, antiretroviral therapy (ART), and drug resistance studies have focused almost exclusively on human immunodeficiency virus type 1 (HIV-1), resulting in limited information for patients infected with HIV-2 and for those dually infected with HIV-1 and HIV-2. In this study, 20 patients, 12 infected with HIV-2 and 8 dually infected with HIV-1 and HIV-2, all treated with zidovudine (ZDV), lamivudine (3TC), and lopinavir-ritonavir (LPV/r), were followed up longitudinally for about 3 years. For 19/20 patients, viral loads were reduced to undetectable levels; the patient whose viral load remained detectable reported adverse effects associated with LPV/r that had caused him to stop taking all the drugs. HIV-2 strains containing mutations in both the protease and the reverse transcriptase gene that may confer drug resistance were observed in two patients with viral rebound, as early as 130 days (4.3 months) after the initiation of therapy. We conclude that the combination of ZDV, 3TC, and LPV/r is able to provide efficient and durable suppression of HIV-1 and HIV-2 for as long as 3 years in HIV-2-infected and dually infected patients. However, the emergence of HIV-1 and HIV-2 strains containing drug-resistant mutations can compromise the efficacy of this highly active ART.

Abstract
OBJECTIVE We evaluated the feasibility of the oligonucleotide ligation assay (OLA), a specific, sensitive, and economical ligase-based point mutation assay designed to detect HIV-1 drug-resistance mutations at 12 codons of HIV-1 subtype B pol, for potential use in resource-poor settings. METHODS Specimens from HIV-1-infected individuals collected by 7 international laboratories, including subtypes A, B, C, D, F, G, J, and recombinants AE and AG, were tested by the OLA developed for HIV-1 subtype B. Common polymorphisms that interfered with reactivity of the OLA were identified and modified probes designed and evaluated. RESULTS 92.5% (2,410) of 2,604 codons in specimens from 217 individuals were successfully genotyped by the subtype B OLA. A high rate (range 8.3%-31.2%) of indeterminate results (negative OLA reaction for both mutant and wild type) was observed for 5 codons. Modified probes at reverse transcriptase codons 151 and 184 and protease codon 90 increased the rate of valid OLA to 96.1%. CONCLUSIONS The OLA designed for HIV-1 subtype B genotyped most pol codons in non-B subtypes from Asia and Africa but was improved by addition of several modified probes. International laboratories experienced in molecular techniques were able to perform the OLA.

Application of a novel, rapid, and sensitive oligonucleotide ligation assay for detection of cancer-predicting mutations in the precore and basal core promoter of hepatitis B virus.

Abstract
Hepatocellular carcinoma (HCC) and cirrhosis are important causes of mortality worldwide. Persistent hepatitis B virus (HBV) infection is a major cause of these diseases. Double mutations in the basal core promoter (BCP) (A1762T and G1764A) and precore (pre-C) (G1896A) regions of the virus are associated with progression to HCC. The current study is aimed at developing a simple method for screening and detecting BCP and pre-C mutations in HBV carriers. We have developed and validated an oligonucleotide ligation assay (OLA) to detect point mutations in the HBV core gene. We have applied OLA methods to samples from HBV-infected carriers recruited from the Gambia Liver Cancer Study (GLCS) comprising asymptomatic HBsAg carriers, patients with cirrhosis, and patients with HCC. We observed an 89.3% and 95.8% concordance between the OLA and DNA sequencing for BCP and pre-C mutations, respectively. OLA detected the mutations in single-strain infections and in infections with mixtures of wild-type and mutant viruses under conditions where sequencing detected only the single dominant strains. BCP mutations were detected in 75.7% of patients with advanced liver disease (cirrhosis/HCC) compared to 47.6% of asymptomatic carriers, while pre-C mutations were detected in 34.5% of advanced liver disease patients and in 47.6% of asymptomatic HBsAg carriers. There was a significant association between the presence of BCP mutations and advanced liver disease. In conclusion, OLA is a simple, economical, and reliable assay for detection of pre-C and BCP mutations. Its application can lead to improvement in diagnosis and clinical care in regions where HBV is endemic.
