HIV pre-exposure prophylaxis and incidence of sexually transmitted infections in Brazil, 2018 to 2022: An ecological study of PrEP administration, syphilis, and socioeconomic indicators.

BACKGROUND: Human immunodeficiency virus (HIV) pre-exposure prophylaxis (PrEP) is one of the pillars of a combination prevention strategy for reducing the risk of new infections caused by HIV. The daily use of antiretroviral drugs by individuals who are not infected with HIV is required to prevent infection. Although its efficacy has been well established in the literature, in recent years, the decreased supply of antiretroviral drugs has been associated with an increase in the incidence of sexually transmitted infections (STI) and changes in the social determinants of health. An ecological study was conducted covering a five-year period (2018-2022), starting from the year of initiation of PrEP administration in Brazilian state capitals. PRINCIPAL FINDINGS: Descriptive analysis was performed, and the spatial distribution of study data was taken into account. Correlation analysis was used to assess the association between PrEP administration, the incidence and detection rate of STI, and socioeconomic data. The southern region showed the highest incidence rates of STI, but the northern and northeastern regions demonstrated the worst socioeconomic indicators, especially those related to illiteracy and basic sanitation. PrEP administration was significantly correlated with illiteracy (ρ = -0.658), per capita income (ρ = 0.622), public garbage collection (ρ = 0.612), syphilis (ρ = 0.628) and viral hepatitis (ρ = 0.419) incidences. Further, all STI were significantly associated with illiteracy and per capita income. SIGNIFICANCE: Our findings highlight the need to continue exploring PrEP use and rising syphilis rates. In terms of policy, PrEP administration appears to be inversely associated with regions of greater social vulnerability. Further efforts should focus on the social determinants and health needs of this population to improve access to PrEP and reduce social disparities.

Adherence to antiretroviral therapy in people living with HIV with moderate or severe mental disorder.

Human immunodeficiency virus (HIV) infection remains a serious public health concern, with an estimated 38 million people living with HIV (PLHIV). PLHIV are often affected by mental disorders at higher rate than the general population. One challenge in the control and prevention of new HIV infections is adherence to antiretroviral therapy (ART), with PLHIV with mental disorders having seemingly lower adherence than PLHIV without mental disorders. This cross-sectional study assessed adherence to ART in PLHIV with mental disorders who attended the Psychosocial Care Network health facilities in Campo Grande, Mato Grosso do Sul, Brazil, from January 2014 to December 2018. Data from health and medical databases were used to describe clinical-epidemiological profiles and adherence to ART. To assess the associated factors (potential risk or predisposing factors) with ART adherence, we used logistic regression model. Adherence was extremely low (16.4%). Factors associated with poor adherence were lack of clinical follow-up, particularly in middle-aged PLHIV. Other apparently associated factors were living on the streets and having suicidal ideation. Our findings reinforce the need for improvements in the care for PLHIV with mental disorders, especially in the integration between specialized mental health and infectious disease health facilities.
