    In this dissertation, treatment adherence among non-Western European MLWH living in the Netherlands was investigated, with a particular focus on adherence to cART. This dissertation contains studies that explored different ways to meas

    Self-reported adherence and pharmacy refill adherence are both predictive for an undetectable viral load among HIV-infected migrants receiving cART

    HIV-infected migrants were shown to have poorer treatment outcomes than Dutch HIV-infected patients, often due to worse treatment adherence. Self-reported adherence would be an easy way to monitor adherence, but its validity relative to pharmacy refill adherence has not been extensively evaluated in migrants. All HIV-infected migrants older than 18 years and in care at the two Rotterdam HIV-treatment centers were eligible. Refill data with leftover medication (PRL) (residual pill count) were obtained from their pharmacies up to 15 months prior to inclusion. Self-reported adherence to combination Antiretroviral Therapy was assessed by four questions about adherence at inclusion. Additionally, risk factors for pharmacy refill non-adherence were examined. In total, 299 HIV-infected migrants were included. Viral load (VL) was detectable in 11% of the patients. Specificity of PRL was 53% for patients with an adherence of 100% and decreased with lower cut-off values. Sensitivity and negative predictive value (NPV) were 68% and 15% and increased with lower cut-off values. Positive predictive value (PPV) was around 93% for all cut-off values. Using the self-reported questions, 139 patients (47%) reported to be adherent. Sensitivity was 49% and specificity was 72%. PPV and NPV were 95% and 13%. No risk factors for pharmacy refill non-adherence were found in multivariable analyses. Both PRL and self-reported adherence, can predict undetectable VL in HIV-infected migrants. PPV and NPV are similar for both methods. This study shows that using four self-reported items is sufficient to predict adherence which is crucial for optimal clinical outcome in HIV-infected migrants

    Risk factors for non-adherence to cART in immigrants with HIV living in the Netherlands: Results from the Rotterdam ADherence (ROAD) project

    In the Netherlands, immigrant people living with HIV (PLWH) have poorer psychological and treatment outcomes than Dutch PLWH. This cross-sectional field study examined risk factors for non-adherence to combination Antiretroviral Therapy (cART) among immigrant PLWH. First and second generation immigrant PLWH attending outpatient clinics at two HIV-treatment centers in Rotterdam were selected for this study. Socio-demographic and clinical characteristics for all eligible participants were collected from an existing database. Trained interviewers subsequently completed questionnaires together with consenting participants (n = 352) to gather additional data on socio-demographic characteristics, psychosocial variables, and self-reported adherence to cART. Univariable and multivariable logistic regression analyses were conducted among 301 participants who had used cART 6 months prior to inclusion. Independent risk factors for self-reported non-adherence were (I) not having attended formal education or only primary school (OR = 3.25; 95%CI: 1.28-8.26, versus University), (II) experiencing low levels of social support (OR = 2.56; 95%CI: 1.37-4.82), and (III) reporting low treatment adherence self-efficacy (OR = 2.99; 95%CI: 1.59-5.64). Additionally, HIV-RNA >50 copies/ml and internalized HIV-related stigma were marginally associated (P<0.10) with non-adherence (OR = 2.53; 95%CI: 0.91-7.06 and OR = 1.82; 95%CI: 0.97-3.43). The findings that low educational attainment, lack of social support, and low treatment adherence self-efficacy are associated with non-adherence point to the need for tailored supportive interventions. Establishing contact with peer immigrant PLWH who serve as role models might be a successful intervention for this specific population

    Late Presentation of HIV Infection in the Netherlands: Reasons for Late Diagnoses and Impact on Vocational Functioning

    Late diagnosis of HIV remains a major challenge in the HIV epidemic. In Europe, about 50% of all people living with HIV are diagnosed late after infection has occurred. Insight into the reasons for late diagnoses is necessary to increase the number of early diagnoses and optimize treatment options. This qualitative study explored the experiences of 34 late-presenters through in-depth semi-structured interviews. A variety of reasons for late diagnoses emerged from our data and led to a division into four groups, characterized by two dimensions. Regarding vocational functioning, the consequences of late diagnoses were health-related problems prior to and since diagnosis, and problems concealing the HIV status. Healthcare providers should offer HIV tests to groups at risk, and be alert for clinical HIV indicator conditions. It is recommended to increase awareness of HIV transmission routes, symptoms and tests, and the benefits of early testing and early entry to HIV care
