Show moreBackground. The COVIH study is a prospective coronavirus disease 2019 (COVID-19) vaccination study in 1154 people with HIV (PWH), of whom 14% showed reduced antibody levels after primary vaccination. We evaluated whether an additional vaccination boosts immune responses in these hyporesponders.Methods. The primary end point was the increase in antibodies 28 days after additional mRNA-1273 vaccination. Secondary end points included neutralizing antibodies, S-specific T-cell and B-cell responses, and reactogenicity.Results. Of the 66 participants, 40 previously received 2 doses ChAdOx1-S, 22 received 2 doses BNT162b2, and 4 received a single dose Ad26.COV2.S. The median age was 63 years (interquartile range [IQR], 60-66), 86% were male, and median CD4(+) T-cell count was 650/mu L (IQR, 423-941). The mean S1-specific antibody level increased from 35 binding antibody units (BAU)/mL (95% confidence interval [CI], 24-46) to 4317 BAU/mL (95% CI, 3275-5360) (P<.0001). Of all participants, 97% showed an adequate response and the 45 antibody-negative participants all seroconverted. A significant increase in the proportion of PWH with ancestral S-specific CD4(+) T cells (P=.04) and S-specific B cells (P=.02) was observed.Conclusions. An additional mRNA-1273 vaccination induced a robust serological response in 97% of PWH with a hyporesponse after primary vaccination. Show less

Show morePolicy-makers and clinicians are faced with a gap of evidence to guide policy on standards for HIV outpatient care. Ongoing debates include which settings of care improve health outcomes, and how many HIV-infected patients a health-care provider should treat to gain and maintain expertise. In this article, we evaluate the studies that link health-care facility and care provider characteristics (i.e., structural factors) to health outcomes in HIV-infected patients. We searched the electronic databases MEDLINE, PUBMED, and EMBASE from inception until 1 January 2015. We included a total of 28 observational studies that were conducted after the introduction of combination antiretroviral therapy in 1996. Three aspects of the available research linking the structure to quality of HIV outpatient care were evaluated: (1) assessed structural characteristics (i.e., health-care facility and care provider characteristics); (2) measures of quality of HIV outpatient care; and (3) reported associations between structural characteristics and quality of care. Rather than scarcity of data, it is the diversity in methodology in the identified studies and the inconsistency of their results that led us to the conclusion that the scientific evidence is too weak to guide policy in HIV outpatient care. We provide recommendations on how to address this heterogeneity in future studies and offer specific suggestions for further reading that could be of interest for clinicians and researchers.

Show moreObjective:Successful treatment of people infected with HIV requires that patients are retained in HIV care, use combination antiretroviral therapy (cART) and ultimately reach and sustain viral suppression. Our aim was to identify health facility characteristics associated with these steps in the cascade of HIV care.Design:Retrospective cohort study.Methods:We included data from all adult HIV-1-infected patients who entered care in the Netherlands between 2007 and 2013 (N=7120). Multivariate logistic regression was used to examine the associations between health facility characteristics and the outcomes currently in care', initiated cART', and viral suppression'.Results:The proportion of patients currently in care' was high in all 26 treatment centres. cART initiation was positively associated with the accreditation of the health facility [OR (odds ratio): 1.62; 95% CI (confidence interval): 1.18-2.23] and the performance of an internal audit in the preceding 3 years (OR: 1.36; 95% CI: 1.02-1.81). The odds of cART initiation were higher in middle-sized (OR: 2.00; 95% CI: 1.25-3.21) and large HIV treatment centres (OR: 1.80; 95% CI: 1.14-2.84) compared with small centres (<300 HIV-infected patients). Viral suppression was negatively associated with the presence of a social worker in the HIV treatment team (OR: 0.62; 95% CI: 0.43-0.91).Conclusions:Our results confirm that appointing expert HIV treatment centres facilitates retention in care and that a minimum volume requirement may be desirable. Our findings suggest that quality assessment through accreditation and the measurement of performance benefits the delivery of HIV care. Copyright (C) 2016 Wolters Kluwer Health, Inc.
