Risk of Multiple Sclerosis in People Living with HIV: An International Cohort Study.

Objective: There has been interest in a possible negative association between HIV and multiple sclerosis (MS). We aimed to compare the risk of MS in a cohort of individuals living with HIV to that in the general population.

Methods: Population-based health data were accessed for 2 cohorts of HIV-positive persons from Sweden and British Columbia, Canada.

Identification of people with low prevalence diseases in administrative healthcare records: A case study of HIV in British Columbia, Canada.

Introduction: Case-finding algorithms can be applied to administrative healthcare records to identify people with diseases, including people with HIV (PWH). When supplementing an existing registry of a low prevalence disease, near-perfect specificity helps minimize impacts of adding in algorithm-identified false positive cases. We evaluated the performance of algorithms applied to healthcare records to supplement an HIV registry in British Columbia (BC), Canada.

Tobacco smoking and HIV-related immunologic and virologic response among individuals of the Canadian HIV Observational Cohort (CANOC).

We assessed the relationship between tobacco smoking and immunologic and virologic response among people living with HIV (PLWH) initiating combination antiretroviral therapy (cART) in the Canadian HIV Observational Cohort (CANOC). Positive immunologic and virologic response, respectively, were defined as ≥50 cells/mm CD4 count increase (CD4+) and viral suppression ≤50 copies/mL (VL+) within 6 months of cART initiation. Using multinomial regression, we examined the relationship between smoking, immunologic, and virologic response category.

Incidence of diabetes mellitus among people living with and without HIV in British Columbia, Canada between 2001 and 2013: a longitudinal population-based cohort study.

Introduction: People living with HIV (PLHIV) are increasingly at risk of age-related comorbidities such as diabetes mellitus (DM). While DM is associated with elevated mortality and morbidity, understanding of DM among PLHIV is limited. We assessed the incidence of DM among people living with and without HIV in British Columbia (BC), Canada, during 2001-2013.

Progression of liver fibrosis following acute hepatitis C virus infection in HIV-positive MSM.

Background: Whether continued, accelerated liver fibrosis progression occurs following acute hepatitis C virus infection (AHCVI) in HIV-positive MSM is unknown.

Design And Methods: HIV-positive MSM from the AIDS Therapy Evaluation in the Netherlands and MSM Observational Study for Acute Infection with Hepatitis C-cohorts with primary AHCVI and at least one fibrosis-4 (FIB-4) measurement less than 2 years before and 1 year after estimated AHCVI were included. Mixed-effect linear models were used to evaluate (time-updated) determinants of FIB-4 levels over time.

HIV-1 status is independently associated with decreased erectile function among middle-aged MSM in the era of combination antiretroviral therapy.

Introduction: HIV-1-infected MSM more often experience sexual dysfunctions than the general population. We assessed associations between HIV-1 status and decreased sexual functioning among MSM.

Methods: We used cross-sectional data from 399 HIV-1-infected MSM mostly on combination antiretroviral therapy (cART) and 366 HIV-1-uninfected MSM aged at least 45 years participating in the AGEhIV Cohort Study.

The 'COmorBidity in Relation to AIDS' (COBRA) cohort: Design, methods and participant characteristics.

Background: Persons living with HIV on combination antiretroviral therapy (cART) may be at increased risk of the development of age-associated non-communicable comorbidities (AANCC) at relatively young age. It has therefore been hypothesised that such individuals, despite effective cART, may be prone to accelerated aging.

Objective: The COmorBidity in Relation to AIDS (COBRA) cohort study was designed to investigate the potential causal link between HIV and AANCC, amongst others, in a cohort of middle-aged individuals with HIV with sustained viral suppression on cART and otherwise comparable HIV-negative controls.

Higher Prevalence and Faster Progression of Chronic Kidney Disease in Human Immunodeficiency Virus-Infected Middle-Aged Individuals Compared With Human Immunodeficiency Virus-Uninfected Controls.

Background: Human immunodeficiency virus (HIV)-infected individuals are at increased risk of chronic kidney disease (CKD). Human immunodeficiency virus infection, traditional CKD risk factors, and combination antiretroviral therapy (cART) may all contribute.

Methods: We compared prevalence of renal impairment (estimated glomerular filtration rate [eGFR] <60 mL/min/1.

Suboptimal primary and secondary cardiovascular disease prevention in HIV-positive individuals on antiretroviral therapy.

Background We aimed to identify the prevalence of cardiovascular risk factors, and investigate preventive cardiovascular medication use and achievement of targets as per Dutch cardiovascular risk management guidelines among human immunodeficiency virus (HIV)-positive and HIV-negative individuals. Design The design was a cross-sectional analysis within an ongoing cohort study. Methods Data on medication use and cardiovascular disease prevalence were available for 528 HIV-positive and 521 HIV-negative participants.

Impact of comorbidity and ageing on health-related quality of life in HIV-positive and HIV-negative individuals.

Background: HIV-infected individuals may be at risk for the premature onset of age-associated noncommunicable comorbidities. Being HIV-positive, having comorbidities and being of higher age may adversely impact health-related quality of life (HRQL). We investigated the possible contribution of HIV infection, comorbidities and age on HRQL and depression.

Cigarette Smoking and Inflammation, Monocyte Activation, and Coagulation in HIV-Infected Individuals Receiving Antiretroviral Therapy, Compared With Uninfected Individuals.

Smoking may affect cardiovascular disease risk more strongly in human immunodeficiency virus (HIV)-infected individuals than HIV-uninfected individuals. We hypothesized that an interaction at the level of the immune system may contribute to this increased risk. We assessed soluble markers of inflammation (high-sensitivity C-reactive protein [hsCRP]), immune activation (soluble [s]CD14 and sCD163), and coagulation (D-dimer) in HIV-infected and uninfected never, former, and current smokers.

Difference in Aortic Stiffness Between Treated Middle-Aged HIV Type 1-Infected and Uninfected Individuals Largely Explained by Traditional Cardiovascular Risk Factors, With an Additional Contribution of Prior Advanced Immunodeficiency.

Background: Patients with HIV, even with suppressed viremia on combination antiretroviral therapy, are at increased risk for cardiovascular disease. The underlying pathophysiology remains to be clarified. Aortic stiffness, known to be associated with cardiovascular disease in the general population, was investigated in a cohort of HIV type 1 (HIV 1)-infected and similar but uninfected individuals.

Higher Prevalence of Hypertension in HIV-1-Infected Patients on Combination Antiretroviral Therapy Is Associated With Changes in Body Composition and Prior Stavudine Exposure.

Background: Individuals infected with human immunodeficiency virus (HIV) have a higher risk of cardiovascular disease, potentially partly mediated by a higher prevalence of hypertension. We therefore examined the prevalence and determinants of hypertension in HIV-1-infected patients compared with appropriate HIV-negative controls.

Methods: Data from 527 HIV-1-infected and 517 HIV-uninfected participants at the time of enrollment into the ongoing AGEhIV Cohort Study were analyzed.

Liver fibrosis in HIV-infected individuals on long-term antiretroviral therapy: associated with immune activation, immunodeficiency and prior use of didanosine.

Background: It is unclear whether HIV infection is associated with liver fibrosis in the absence of chronic hepatitis B or C virus (HBV/HCV) coinfection. We compared prevalence of liver fibrosis, noninvasively assessed by the Fibrosis-4 (FIB-4) index, between HIV-infected patients and uninfected controls, and explored determinants of a higher FIB-4 score, indicative of more liver fibrosis.

Methods: FIB-4 was assessed in HIV-uninfected and HIV-1-infected, predominantly virologically suppressed participants of the AGEhIV Cohort Study without HBV and/or HCV coinfection, and aged at least 45.

HIV-Associated Neuroretinal Disorder in Patients With Well-Suppressed HIV-Infection: A Comparative Cohort Study.

Purpose: Loss of neuroretinal structure and function, ascribed to a 'HIV-associated Neuroretinal Disorder' (HIV-NRD), in the absence of ocular opportunistic infections, has been reported in HIV-infected individuals treated with combination antiretroviral therapy (cART). Whether HIV-infected individuals with prolonged well-suppressed infection remain at risk for HIV-NRD, is unknown.

Methods: Ninety-two HIV-infected men with suppressed viremia on cART for at least 12 months (HIV+) and 63 HIV-uninfected, highly comparable, male controls (HIV-), aged at least 45 years, underwent functional measurements of spatial (Pelli Robson contrast sensitivity [PR CS]) and temporal contrast sensitivity (TCS) and straylight, as well as spectral-domain optical coherence tomography analysis measured total and individual retinal layer thickness.

HIV infection is independently associated with frailty in middle-aged HIV type 1-infected individuals compared with similar but uninfected controls.

Background: Frailty is an age-related syndrome of decreased physiological reserve and resistance to stressors, associated with increased morbidity and mortality in the general elderly population. An increased prevalence of frailty has been reported amongst HIV-infected individuals.

Methods: Fried frailty phenotype was systematically assessed in predominantly virologically suppressed HIV type 1 (HIV-1)-infected and otherwise comparable HIV-uninfected participants aged at least 45 at enrollment into the AGEhIV Cohort Study.

Low bone mineral density in patients with well-suppressed HIV infection: association with body weight, smoking, and prior advanced HIV disease.

Background: Human immunodeficiency virus (HIV) and combination antiretroviral therapy (cART) may both contribute to the higher prevalence of osteoporosis and osteopenia in HIV-infected individuals.

Methods: Using dual-energy X-ray absorptiometry, we compared lumbar spine, total hip, and femoral neck bone mineral density (BMD) in 581 HIV-positive (94.7% receiving cART) and 520 HIV-negative participants of the AGEhIV Cohort Study, aged ≥45 years.
