ABSTRACT

Background By the end of 2017, an estimated 83% of people living with HIV in Malaysia knew their serostatus. However, the Ministry of Health reported a high proportion of those newly diagnosed had low CD4 counts <200 cells/µL, indicating late presentation for testing may be pervasive. METHODS: A qualitative study was conducted to explore the context and experiences of people at risk of HIV infection testing and seeking treatment later in the course of their infection. Participants recruited (n = 20) were HIV positive, aged >18 years who fit the description of late presentation (World Health Organization defined as CD4 cell count <350 cells/µL). Semi-structured interviews were conducted, and a framework approach was used to interrogate the data. RESULTS: Many participants perceived themselves at low risk of HIV infection and did not undergo routine voluntary testing; rather, they were diagnosed when seeking treatment for serious illness or as part of mandatory employment-related testing. Perceived lack of confidentiality and potential discriminatory behaviour at public health facilities were significant deterrents to testing. Participants were satisfied with HIV treatment, but rarely sought psychosocial support in order to 'protect' their privacy. CONCLUSION: Unless drivers of HIV infection are effectively addressed, including stigmatising and discriminatory practices, and low health literacy, the occurrence of late presentation will persist. Their collective impact will not only jeopardise efforts to improve the treatment cascade, but may also impact engagement with other biomedical prevention and care technologies.

ABSTRACT

HIV viral load (VL) testing is the recommended method for monitoring the response of people living with HIV and receiving antiretroviral therapy (ART). The availability of standard plasma VL testing in low- and middle-income countries (LMICs), and access to this testing, are limited by the need to use fresh plasma. Good specimen collection methods for HIV VL testing that are applicable to resource-constrained settings are needed. We assessed the diagnostic performance of the filtered dried plasma spot (FDPS), created using the newly developed, instrument-free VLPlasma device, in identifying treatment failure at a VL threshold of 1,000 copies/ml in fresh plasma. Performance was compared with that of the conventional dried blood spot (DBS). Venous blood samples from 201 people living with HIV and attending an infectious disease clinic in Malaysia were collected, and HIV VL was quantified using fresh plasma (the reference standard), FDPS, and DBS specimens. VL testing was done using the Roche Cobas AmpliPrep/Cobas TaqMan v2.0 assay. At a threshold of 1,000 copies/ml, the diagnostic performance of the FDPS was superior (sensitivity, 100% [95% confidence interval {CI}, 89.1 to 100%]; specificity, 100% [95% CI, 97.8 to 100%]) to that of the DBS (sensitivity, 100% [95% CI, 89.4 to 100%]; specificity, 36.8% [95% CI, 29.4 to 44.7%]) (P < 0.001). A stronger correlation was observed between the FDPS VL and the plasma VL (r = 0.94; P < 0.001) than between the DBS VL and the plasma VL (r = 0.85; P < 0.001). The mean difference in VL measures between the FDPS and plasma (plasma VL minus FDPS VL) was 0.127 log10 copies/ml (standard deviation [SD], 0.32), in contrast to -0.95 log10 copies/ml (SD, 0.84) between the DBS and plasma. HIV VL measurement using the FDPS outperformed that with the DBS in identifying treatment failure at a threshold of 1,000 copies/ml and compared well with the quantification of VL in plasma. The FDPS can be an attractive alternative to fresh plasma for improving access to HIV VL monitoring among people living with HIV on ART in LMICs.
