Increase in transmitted drug resistance in migrants from sub-Saharan Africa diagnosed with HIV-1 in Sweden
- 2018

Tidskriftsartikel (refereegranskat)abstract
- Objective: To study the trends of transmitted drug resistance (TDR) in HIV-1 patients newly diagnosed in Sweden, 2010-2016. Design: Register-based study including all antiretroviral therapy-naive patients ≥18 years diagnosed with HIV-1 in Sweden 2010-2016. Methods: Patient data and viral pol sequences were extracted from the national InfCareHIV database. TDR was defined as the presence of surveillance drug resistance mutations (SDRMs). A CD4+ T-cell decline trajectory model estimated time of infection. Phylogenetic inference was used for cluster analysis. Chi-square tests and logistic regressions were used to investigate relations between TDR, epidemiological and viral factors. Results: One thousand, seven hundred and thirteen pol sequences were analyzed, corresponding to 71% of patients with a new HIV-1 diagnosis (heterosexuals: 53%; MSM: 34%). The overall prevalence of TDR was 7.1% (95% CI 5.8-8.3%). Nonnucleoside reverse transcriptase inhibitor (NNRTI) TDR increased significantly from 1.5% in 2010 to 6.2% in 2016, and was associated to infection and/or origin in sub-Saharan Africa (SSA). An MSM transmission cluster dating back to the 1990s with the M41L SDRM was identified. Twenty-five (1.5%) patients exhibited TDR to tenofovir (TDF; n = 8), emtricitabine/lamivudine (n = 9) or both (n = 8). Conclusion: NNRTI TDR has increased from 2010 to 2016 in HIV-1-infected migrants from SSA diagnosed in Sweden, mirroring the situation in SSA. TDR to tenofovir/emtricitabine, used in preexposure prophylaxis, confirms the clinical and epidemiological need for resistance testing in newly diagnosed patients.

- OBJECTIVE: To assess antiretroviral therapy (ART) adherence among people with HIV (PWH) in Canada and identify baseline characteristics associated with suboptimal adherence (<95%). DESIGN: Retrospective observational study using data from the National Prescription Drug Utilization Information System and Régie de l'assurance maladie Quebec (RAMQ) Public Prescription Drug Insurance Plan. METHODS: This analysis included PWH aged 18 years or older who initiated an ART regimen and were followed for at least 12 months (2010-2020). Patient characteristics were summarized using medical/pharmacy claims data from seven provinces (Alberta, Manitoba, New Brunswick, Newfoundland and Labrador, Ontario, Saskatchewan, and Quebec). ART regimen at index date (first dispensing of a regimen including a core agent) was defined as a single-tablet or multitablet regimen (MTR). Adherence was calculated using a Proportion of Days Covered approach, based on ART dispensing, recorded between April 2010 and the last available date. Multivariate linear regression analysis was used to determine correlations between suboptimal adherence and baseline characteristics. RESULTS: We identified 19 322 eligible PWH, 44.7% of whom had suboptimal adherence (<95%). Among 12 594 PWH with evaluable baseline data, 10 673 (84.8%) were ART-naive, 74.2% were men, mean age was 42.9 years, and 54.1% received a MTR as their ART. Based on multivariate regression analysis, suboptimal adherence was significantly associated with multitablet ART ( P < 0.001) and younger age ( P < 0.001) but not sex. CONCLUSION: Almost half of adult PWH in Canada had suboptimal adherence to ART. Better understanding of factors influencing adherence may help address gaps in current care practices that may impact adherence.

- Objective: To understand the risk of HIV acquisition through occupational exposure among rural South African traditional healers, notably via the practice of traditional skin incisions with razors.Design: A random sample of traditional healers living in South Africa participated in a cross-sectional survey that included a rapid HIV test.Setting: Rural Bushbuckridge district of Mpumalanga, South Africa.Participants: Traditional healers.Intervention: Pretest counseling, posttest counseling, and referral to care if HIV seropositive.Main outcome measure(s): HIV infection.Results: Among healers who reported a previous positive test result or accepted an HIV test (96%), HIV prevalence was 30% (95% confidence interval: 23–37%). During their careers, 98% of healers reported conducting at least one ‘vaccination’ (as traditional incisions are called), 32% reported always using gloves when conducting these procedures, 29 (14%) reported patient blood touching their bare skin. Healers who reported exposure to patient blood had a higher HIV prevalence than their nonexposed colleagues (adjusted risk ratio: 2.35, 95% confidence interval: 1.55–3.56, P = 0.001).Conclusion: Nearly all traditional healers are routinely performing minimally invasive skin incisions that could expose them to patient blood. The lack of training and access to personal protective equipment increase their risk of acquisition of blood–borne pathogens, including HIV. Given the widespread practice of traditional skin incisions across southern Africa, and the higher levels of HIV among traditional healers exposed to patient blood, it is likely that traditional healers are a hitherto unrecognized key population at disproportionate risk of acquiring HIV.

- Enzyme-linked immunosorbent assays (ELISA) were developed for the demonstration of antibodies to HIV-2 using disrupted virions of the SBL-6669 isolate of HIV-2 and the so-called human T-lymphotropic virus type IV (HTLV-IV), recently found to be identical with the simian immunodeficiency virus (SIVmac), as antigens. Three hundred sera from West African subjects, attending an outward clinic in Bissau for examination of suspected tuberculosis, were tested by these two assays as well as by a commercially available anti-HIV-2 ELISA (ELAVIA II). Fifty of these sera were positive in all three ELISAs as well as in Western blot tests against HTLV-IV. Thirty-eight of these positive sera were also tested by an anti-HIV-2 Western blot kit (LAV-Blot II) with positive results. The ELISAs based on SBL-6669 and HTLV-IV antigens had a specificity of 99.6% (one false positive among 250 negative sera) whereas the specificity of ELAVIA II was 94.6% using the recommended cut-off value and 98.4% using a higher cut-off value. Another 58 sera from West African patients, clinically suspected of having AIDS or HIV-related disease, were tested for HIV-2/HTLV-IV antibodies by Western blot and by ELISA against SBL-6669 and HTLV-IV antigens; all of the 30 sera which were positive by Western blot were found to be positive in both ELISAs.(ABSTRACT TRUNCATED AT 250 WORDS)
