RESUMEN

BACKGROUND: Depression is common in people with human immunodeficiency virus (HIV) and hepatitis C virus (HCV), with biological and psychosocial mechanisms at play. Direct acting antivirals (DAA) result in high rates of sustained virologic response (SVR), with minimal side-effects. We assessed the impact of SVR on presence of depressive symptoms in the HIV-HCV coinfected population in Canada during the second-generation DAA era (2013-2020). METHODS: We used data from the Canadian CoInfection Cohort (CCC), a multicenter prospective cohort of people with a HIV and HCV coinfection, and its associated sub-study on food security. Because depression screening was performed only in the sub-study, we predicted Center for Epidemiologic Studies Depression Scale-10 classes in the CCC using a random forest classifier and corrected for misclassification. We included participants who achieved SVR and fit a segmented modified Poisson model using an interrupted time series design, adjusting for time-varying confounders. RESULTS: We included 470 participants; 58% had predicted depressive symptoms at baseline. The median follow-up was 2.4 years (interquartile range [IQR]: 1.0-4.5.) pre-SVR and 1.4 years (IQR: 0.6-2.5) post-SVR. The pre-SVR trend suggested depressive symptoms changed little over time, with no immediate level change at SVR. However, post-SVR trends showed a reduction of 5% per year (risk ratio: 0.95 (95% confidence interval [CI]: .94-.96)) in the prevalence of depressive symptoms. CONCLUSIONS: In the DAA era, predicted depressive symptoms declined over time following SVR. These improvements reflect possible changes in biological pathways and/or better general health. If such improvements in depression symptoms are durable, this provides an additional reason for treatment and early cure of HCV.

RESUMEN

BACKGROUND: Patterns of vitamin D intake are relatively unexplored among women living with HIV, despite its importance for women's health. We compared vitamin D dietary and supplement intakes in women with HIV and population-based national controls and investigated barriers to intake. METHODS: In this case-control study, women with HIV in the Children and Women: AntiRetrovirals and Markers of Aging (CARMA) cohort were matched with Canadian Multicentre Osteoporosis Study (CaMos) controls. Participants were queried for vitamin D in dairy consumption, supplementation/dosage, and sociodemographic variables. We assessed barriers to supplementation and factors associated with dietary intake by regression modelling. RESULTS: Ninety-five women living with HIV were age-matched to 284 controls. Women with HIV had lower income and bone mineral density and were more likely to smoke, take multiple medications and be non-white. Vitamin D dietary intake was lower in women living with HIV versus controls [0.76 vs. 1.79 µg/day; adjusted odds ratio (aOR) for greater than or equal to median intake 0.29 (0.12-0.61), p = 0.002], but any supplementation was higher [62.2% vs. 44.7%; aOR = 3.44 (95% CI: 1.16-11.00), p = 0.03]. Total vitamin D intake was similar between groups. Smoking was associated with no supplementation; non-white ethnicity and low income were related to lower dietary intake. CONCLUSIONS: Women living with HIV showed lower dietary vitamin D intake but higher supplementation rates, suggesting that care providers are promoting supplementation. Women living with HIV who smoke, have low incomes and are non-white may particularly benefit from targeted efforts to improve vitamin D intake.

RESUMEN

OBJECTIVES: Our objective was to report the baseline characteristics of participants in the Canadian HIV and Aging Cohort Study (CHACS) and present amendments to the initial protocol. METHODS: CHACS is a multi-centred prospective cohort study that was initially set from 2011 to 2016 and will now continue recruitment until 2024. Four additional years of follow-up have been added, and additional outcomes and covariates will be prospectively collected. Frailty will be assessed using a modified version of the Fried's frailty phenotype. The four interrelated aspects of gender-gender roles, gender identity, gender relationships, and institutionalized gender-will be measured using the GENESIS-PRAXY questionnaire. Diet will be assessed using a validated, web-based, self-administered food frequency questionnaire. RESULTS: A total of 1049 participants (77% people living with HIV) were recruited between September 2011 and September 2019. Median age at baseline was 54 years (interquartile range 50-61). Most participants were male (84%) and white (83%). Compared with participants without HIV, those with HIV were more likely to be male; to report lower education levels and incomes; to be more sedentary; to use tobacco, recreational, and prescription drugs; to report a personal history of cardiovascular diseases; and to be frail. CONCLUSIONS: The new assessments added to the CHACS protocol will allow for an even more detailed portrait of the pathways leading to accentuated aging for people living with HIV. Participants in the CHACS cohort display important differences in socio-economic and cardiovascular risk factors according to HIV serostatus. These imbalances must be taken into account for all further inferential analyses.

RESUMEN

We investigated associations between (1) housing status (four categories measuring housing stability) and outcomes along the HIV care continuum (not currently on antiretroviral therapy [ART]; sub-optimal ART adherence [< 95% in the last 3-4 weeks]; unsuppressed viral load [> 200 copies/ml], median CD4 < 200 in the last six months), and (2) housing status and unmet primary, dental and mental health care needs in the last six months among WLWH. Housing status was defined according to the Canadian Definition of Homelessness and had four categories: unsheltered (i.e., living in ≥ 1 unsheltered location [e.g., street, abandoned buildings]), unstable (i.e., living in ≥ 1 unstable location [e.g., shelter, couch surfing]), supportive housing (i.e., only living in supportive housing), and stable housing (i.e., only living in one's own housing; reference). At baseline, in the last six months, 47.3% of participants reported unstable housing, followed by 24.4% unsheltered housing, 16.4% stable housing, and 11.9% supportive housing. Overall, 19.1% of the full sample (N = 336, 2010-2019) reported not currently on ART; among participants on ART, 28.0% reported sub-optimal ART adherence. Overall, 32.1% had recent unsuppressed viral load. Among a subsample (n = 318, 2014-2019), 15.7% reported unmet primary care needs, 26.1% unmet dental care needs, and 16.4% unmet mental health care needs. In adjusted models, being unsheltered (vs. stable housing) was associated with not currently on ART, unsuppressed viral load, and unmet primary and dental care needs. Housing and health services need to be developed with and for WLWH to address structural inequities and fulfill basic rights to housing and health.

RESUMEN

Given sub-optimal HIV care outcomes for people living with HIV (PLWH) post-release from incarceration, we systematically searched peer-reviewed literature (2010-2021) describing controlled trial interventions aimed at improving Antiretroviral Therapy (ART) adherence and care linkage following release from correctional facilities for PLWH. Of 392 studies, 16 (4%) met the inclusion criteria. All studies were conducted in the United States and involved some form of intensive case management. Trials that scored highest in terms of study quality provided cell phones for engagement, reported sustained viral load suppression as a measurable outcome to infer ART adherence, and measured longitudinal data collected for at least 3-to-6 months following release. The two trials that demonstrated improved HIV viral load suppression involved Peer Navigators, and incentivized undetectable viral load, respectively. Facilitating support for addictions and addressing other social and structural barriers to achieving optimal health is also of vital importance in bridging care gaps for PLWH.


RESUMEN: Debido a los resultados suboptimos en los cuidados de las personas que viven con VIH después de su liberación del encarcelamiento, nosotros realizamos una revisión sistemática de la literatura (2010­2021) que describe ensayos control de intervenciones para mejorar la adherencia a la terapia antiretrovirales (TAR) y el vinculo con la atención medica después de la liberación del encarcelamiento de las personas que viven con VIH. De los 392 estudios, 16 (4%) cumplieron con los criterios de inclusión. Todos los estudios fueron realizados en los Estados Unidos e incluyen alguna forma de cuidados con manejo intensivo. Los ensayos que tenían los puntajes mas altos en términos de calidad proveían teléfonos celulares para la vinculación, reportaban supresión de la carga viral sostenida como medida indirecta de adherencia al TAR, y han medido datos longitudinales por lo menos de tres a seis meses después de la liberación carcelaria. Los dos ensayos que demostraron mejora en la supresión de la carga viral del VIH involucraban a los pares navegadores e incentivaban la carga viral no detectable, respectivamente. Facilitando el soporte para la adicción y el entendimiento de otras barreras sociales y estructurales para alcanzar una salud optima, es de vital importancia para superar las brechas en la atención de las personas que viven con VIH.

RESUMEN

BACKGROUND: Multiple contraindications to combined hormonal contraceptives (CHC) use exist. The impact of these factors on contraceptive choice, particularly among women living with HIV (WLWH), is not well understood. We measured and compared the prevalence of contraceptive use and contraindications among WLWH and women not living with HIV (controls). METHODS: We examined cross-sectional survey and medical chart data from 83 WLWH and 62 controls, aged 16-49 and sexually active, from 2013-2017. We compared the age-adjusted prevalence and types of contraceptives used in the last month and the proportion of women with CHC contraindications, including drug interactions, medical comorbidities, and smoking at ≥ 35 years old. All WLWH received care at an interdisciplinary, women-centred HIV clinic. RESULTS: Compared to controls, WLWH were older (median [IQR)] 39 [34-43] vs 31 [23-41] years; p = 0.003), had less post-secondary education (37% vs 73%; p < 0.001), and more often had household income < $15,000/year (49% vs 30%; p = 0.006). WLWH trended to higher contraceptive prevalence than controls (80% vs 63%; p = 0.06 adjusted for age). Overall hormonal contraceptive use was similar. However, despite controlling for age, WLWH used CHC less (4% vs 18%; p = 0.006) than controls, and had more frequently undergone tubal ligation (12% vs 2%; p = 0.03). WLWH also experienced more CHC contraindications (54% vs 13%; p = 0.0001), including smoking at ≥ 35 years old (30% vs 6%; p = 0.0003) or a CHC-related drug interaction (all antiretroviral related) (25% vs 0%; p = 0.0001). CONCLUSIONS: WLWH attending our interdisciplinary clinic used hormonal contraception at similar rates as controls, though with different types. Differences may reflect different distributions of CHC contraindications. CHC contraindications present barriers to accessing the full range of contraceptive choices for WLWH. Guidelines and education for care providers and WLWH regarding contraceptive choices and drug interactions are needed, especially when care is provided without the benefit of an interdisciplinary women-centered healthcare team.


BACKGROUND: There are many reasons why individuals cannot use combined hormonal contraceptives (CHC). The impact of these reasons on contraceptive choice for women living with HIV (WLWH) are poorly understood. We measured and compared the prevalence of contraceptive choice and factors that may preclude their use in WLWH. METHODS: We examined survey and medical chart data from 83 WLWH and 62 controls (women not living with HIV), aged 16­49 and sexually active, from 2013 to 2017. We compared the prevalence and types of contraceptives used in the last month and the proportion of women with factors that would not allow the use of CHC, including drug interactions, medical conditions, and smoking at ≥ 35 years old. All WLWH received care at a women-centred HIV clinic. RESULTS: Compared to controls, WLWH were older, had less post-secondary education, and more often had household income < $15,000/year. WLWH were more likely to use contraception than controls. Overall hormonal contraceptive use was similar. However, even when accounting for age, WLWH used CHC less than controls, and had more frequently undergone tubal ligation. WLWH also had more reasons that would preclude the use of CHC contraindications including smoking at ≥ 35 years old or a CHC-related drug interaction. CONCLUSIONS: WLWH attending our interdisciplinary clinic used combined hormonal contraception at similar rates as controls, though with different types. Differences may reflect the fact that WLWH more often have factors that do not allow the safe use of CHC. Guidelines and education for care providers and WLWH regarding contraceptive choices and drug interactions are needed.

RESUMEN

BACKGROUND: Noninvasive markers of liver fibrosis such as aspartate aminotransferase-to-platelet ratio (APRI) and transient elastography (TE) have largely replaced liver biopsy for staging hepatitis C virus (HCV). As there is little longitudinal data, we compared changes in these markers before and after sustained virologic response (SVR) in human immunodeficiency virus (HIV)-HCV coinfected patients. METHODS: Participants from the Canadian Coinfection Cohort study who achieved SVR after a first treatment with either interferon/ribavirin or direct acting antivirals (DAAs), with at least 1 pre- and posttreatment fibrosis measure were selected. Changes in APRI or TE (DAA era only) were modeled using a generalized additive mixed model, assuming a gamma distribution and adjusting for sex, age at HCV acquisition, duration of HCV infection, and time-dependent body mass index, binge drinking, and detectable HIV RNA. RESULTS: Of 1981 patients, 151 achieved SVR with interferon and 553 with DAAs; 94 and 382 met inclusion criteria, respectively. In the DAA era, APRI increased (0.03 units/year; 95% credible interval (CrI): -.05, .12) before, declined dramatically during, and then changed minimally (-0.03 units/year; 95% CrI: -.06, .01) after treatment. TE values, however, increased (0.74 kPa/year; 95% CrI: .36, 1.14) before treatment, changed little by the end of treatment, and then declined (-0.55 kPa/year; 95% CrI: -.80, -.31) after SVR. CONCLUSIONS: TE should be the preferred noninvasive tool for monitoring fibrosis regression following cure. Future studies should assess the risk of liver-related outcomes such as hepatocellular carcinoma according to trajectories of fibrosis regression measured using TE to determine if and when it will become safe to discontinue screening.

RESUMEN

BACKGROUND: Women living with hepatitis C virus (HCV) are rarely addressed in research and may be overrepresented within key populations requiring additional support to access HCV care and treatment. We constructed the HCV care cascade among people diagnosed with HCV in British Columbia, Canada, as of 2019 to compare progress in care and treatment and to assess sex/gender gaps in HCV treatment access. METHODS: The BC Hepatitis Testers Cohort includes 1.7 million people who tested for HCV, HIV, reported cases of hepatitis B, and active tuberculosis in BC from 2000 to 2019. Test results were linked to medical visits, hospitalizations, cancers, prescription drugs, and mortality data. Six HCV care cascade stages were identified: (1) antibody diagnosed; (2) RNA tested; (3) RNA positive; (4) genotyped; (5) initiated treatment; and (6) achieved sustained virologic response (SVR). HCV care cascade results were assessed for women, and an 'inverse' cascade was created to assess gaps, including not being RNA tested, genotyped, or treatment initiated, stratified by sex. RESULTS: In 2019, 52,638 people with known sex were anti-HCV positive in BC; 37% (19,522) were women. Confirmatory RNA tests were received by 86% (16,797/19,522) of anti-HCV positive women and 83% (27,353/33,116) of men. Among people who had been genotyped, 68% (6756/10,008) of women and 67% (12,640/18,828) of men initiated treatment, with 94% (5023/5364) of women and 92% (9147/9897) of men achieving SVR. Among the 3252 women and 6188 men not yet treated, higher proportions of women compared to men were born after 1975 (30% vs. 21%), had a mental health diagnosis (42% vs. 34%) and had used injection drugs (50% vs. 45%). Among 1619 women and 2780 men who had used injection drugs and were not yet treated, higher proportions of women than men used stimulants (64% vs. 57%), and opiates (67% vs. 60%). CONCLUSIONS: Women and men appear to be equally engaged into the HCV care cascade; however, women with concurrent social and health conditions are being left behind. Treatment access may be improved with approaches that meet the needs of younger women, those with mental health diagnoses, and women who use drugs.

RESUMEN

Women living with HIV (WLWH) are disproportionately represented among incarcerated populations yet there is a paucity of research on how incarceration shapes HIV treatment outcomes for women. Data is drawn from SHAWNA (Sexual health and HIV/AIDS: Women's Longitudinal Needs Assessment), a longitudinal community-based open research cohort with cis and trans WLWH in Metro Vancouver, Canada (2010-2017). Multivariable logistic regression using generalized estimating equations (GEE) longitudinally modeled the effect of incarceration on virologic suppression (HIV plasma VL < 50 copies/mL), adjusting for potential confounders. Amongst 292 WLWH, the majority (74%) had been incarcerated in their lifetime and 17% were incarcerated over the study period. Exposure to recent incarceration was independently correlated with reduced odds of virologic suppression (AOR: 0.42, 95% CI 0.22-0.80). This study suggests critical need for research and interventions to better address factors shaping ART adherence and retention in care for WLWH, both within correctional centres and following release from prison.

RESUMEN

Women living with HIV (WLWH) are over-represented in corrections in Canada, yet little is known about women's experiences post-release. We used CHIWOS cross-sectional data from WLWH to estimate associations between social determinants of health and HIV-related care outcomes among WLWH with recent (within past year) or ever (before past year) incarceration experience. Lifetime incarceration prevalence was 36.9% (6.5% recent; 30.4% ever), with significant differences by province of residence (British Columbia: 10% recent; 52% ever; Ontario: 5%; 24%; Quebec: 6%; 22%; p < 0.001). In adjusted multinomial logistic regression analyses, compared with never incarcerated, recent incarceration was associated with Indigenous ancestry, lower annual income (< $20,000 CAD), unstable housing, current sex work, injection drug use (IDU), and sub-optimal antiretroviral therapy (ART) adherence, while ever incarceration was associated with current sex work, IDU, and experiencing adulthood violence. Our findings have implications regarding supports needed by WLWH in the post-release period, including ART adherence and achieving health and social goals.

RESUMEN

Despite women living with HIV (WLWH) being disproportionately criminalized and overrepresented within correctional facilities, there remains limited longitudinal research with WLWH examining factors that make WLWH vulnerable to incarceration. Data are drawn from SHAWNA (Sexual health and HIV/AIDS: Women's Longitudinal Needs Assessment), a community-based research cohort with cisgender and transgender WLWH in Metro Vancouver, Canada. Multivariable logistic regression using generalized estimating equations (GEE) and an exchangeable working correlation matrix was used to prospectively model correlates of recent incarceration exposure over a seven-year period. Amongst 289 WLWH, 76% had been incarcerated in their lifetime, and 17% had experienced recent incarceration. In multivariable GEE analysis, younger age (AOR: 0.92 per year older, 95% CI: 0.89-0.96), recent homelessness (AOR: 2.81, 95% CI: 1.46-5.41), recent gender-based (physical and/or sexual) violence (AOR: 2.26, 95% CI: 1.20-4.22) and recent opioid use (AOR: 1.83, 95% CI: 1.00-3.36), were significantly associated with recent incarceration. Lifetime exposure to gender-based violence by police (AOR: 1.97, CI: 0.97-4.02) was marginally associated with increased odds of recent incarceration. This research suggests a critical need for trauma-informed interventions for WLWH during and following incarceration. Interventions must be gender specific, include housing and substance use supports, and address the impact of gender-based violence.

RESUMEN

Love remains hidden in HIV research in favor of a focus on risk. Among 1424 women living with HIV in Canada, we explored (1) whether eight facets of sex and intimacy (marital status, sexual activity, physical intimacy, emotional closeness, power equity, sexual exclusivity, relationship duration, and couple HIV serostatus) may coalesce into distinct relationship types, and (2) how these relationship types may be linked to love as well as various social, psychological, and structural factors. Five latent classes were identified: no relationship (46.5%), relationships without sex (8.6%), and three types of sexual relationships-short term (15.4%), long term/unhappy (6.4%), and long term/happy (23.2%, characterized by equitable power, high levels of physical and emotional closeness, and mainly HIV-negative partners). While women in long-term/happy relationships were most likely to report feeling love for and wanted by someone "all of the time," love was not exclusive to sexual or romantic partners and a sizeable proportion of women reported affection across latent classes. Factors independently associated with latent class membership included age, children living at home, sexism/genderism, income, sex work, violence, trauma, depression, HIV treatment, awareness of treatment's prevention benefits, and HIV-related stigma. Findings reveal the diversity of women's experiences with respect to love, sex, and relationships and draw attention to the sociostructural factors shaping intimate partnering in the context of HIV. A nuanced focus on promoting healthy relationships and supportive social environments may offer a more comprehensive approach to supporting women's overall sexual health and well-being than programs focused solely on sexual risk reduction.

RESUMEN

Background: Highly effective hepatitis C virus (HCV) therapies have spurred a scale-up of treatment to populations at greater risk of reinfection after sustained virologic response (SVR). Reinfection may be higher in HIV-HCV coinfection, but prior studies have considered small selected populations. We assessed risk factors for reinfection after SVR in a representative cohort of Canadian coinfected patients in clinical care. Methods: All patients achieving SVR after HCV treatment were followed with HCV RNA measurements every 6 months in a prospective cohort study. We used Bayesian Cox regression to estimate reinfection rates according to patient reported injection drug use (IDU) and sexual activity among men who have sex with men (MSM). Results: Of 497 patients treated for HCV, 257 achieved SVR and had at least 1 subsequent RNA measurement. During 589 person-years of follow-up (PYFU) after SVR, 18 (7%) became HCV RNA positive. The adjusted reinfection rate (per 1000 PYFU) in the first year after SVR was highest in those who reported high-frequency IDU (58; 95% credible interval [CrI], 18-134) followed by MSM reporting high-risk sexual activity (26; 95% CrI, 6-66) and low-frequency IDU (22; 95% CrI, 4-68). The rate in low-risk MSM (16; 95% CrI, 4-38) was similar to that in reference patients (10; 95% CrI, 4-20). Reinfection rates did not diminish with time. Conclusions: HCV reinfection rates varied according to risk. Measures are needed to reduce risk behaviors and increase monitoring in high-risk IDU and MSM if HCV elimination targets are to be realized.

RESUMEN

Attrition along the cascade of HIV care poses significant barriers to attaining the UNAIDS targets of 90-90-90 and achieving optimal treatment outcomes for people living with HIV. Understanding the correlates of attrition is critical and particularly for women living with HIV (WLWH) as gender disparities along the cascade have been found. We measured the proportion of the 1425 WLWH enrolled in the Canadian HIV Women's Sexual and Reproductive Health Cohort Study (CHIWOS) who had never accessed HIV medical care, who reported delayed linkage into HIV care (>3 months between diagnosis and initial care linkage), and who were not engaged in HIV care at interview (<1 visit in prior year). Correlates of these cascade indicators were determined using univariate and multivariable logistic regression. We found that 2.8% of women had never accessed HIV care. Of women who had accessed HIV care, 28.7% reported delayed linkage and 3.7% were not engaged in HIV care. Indigenous women had higher adjusted odds of both a lack of access and delayed access to HIV care. Also, a younger age, unstable housing, history of recreational drug use, and experiences of everyday racism emerged as important barriers to ever accessing care. Programmatic efforts to support early linkage to and engagement in care for WLWH in Canada must address several social determinants of health, such as housing insecurity and social exclusion, and prioritize engagement of Indigenous women through culturally safe and competent practices.

RESUMEN

BACKGROUND: Combination antiretroviral therapy (cART) as treatment for human immunodeficiency virus (HIV) infection is effective and available, but poor medication adherence limits benefits, particularly in vulnerable populations. In a Kenyan randomized controlled trial, a weekly text-messaging intervention (WelTel) improved cART adherence and HIV viral load (VL). Despite growing evidence for short message service (SMS) text-message interventions in HIV care, there is a paucity of data utilizing these interventions in marginalized or female cohorts. OBJECTIVE: This study was undertaken to assess whether the standardized WelTel SMS text-message intervention applied to a vulnerable, predominantly female, population improved cART adherence and VL. METHODS: We conducted a repeated measures study of the WelTel intervention in high-risk HIV-positive persons by measuring change in VL, CD4 count, and self-reported adherence 12 months before and 12 months after the WelTel intervention was introduced. Inclusion criteria included VL ≥200 copies/mL, indication for treatment, and meeting vulnerability criteria. Participants were given a mobile phone with unlimited texting (where required), and weekly check-in text messages were sent for one year from the WelTel computer platform. Clinical data were collected for control and intervention years. Participants were followed by a multidisciplinary team in a clinical setting. Outcomes were assessed using Wilcoxon signed ranks tests for change in CD4 and VL from control year to study end and mixed-effects logistic regressions for change in cART adherence and appointment attendance. A secondary analysis was conducted to assess the effect of response rate on the outcome by modeling final log10 VL by number of responses while controlling for mean log10 VL in the control year. RESULTS: Eighty-five participants enrolled in the study, but 5 withdrew (final N=80). Participants were predominantly female (90%, 72/80) with a variety of vulnerabilities. Mean VL decreased from 1098 copies/mL in the control year to 439 copies/mL at study end (P=.004). Adherence to cART significantly improved (OR 1.14, IQR 1.10-1.18; P<.001), whereas appointment attendance decreased slightly with the intervention (OR 0.81, IQR 0.67-0.99; P=.03). A response was received for 46.57% (1753/3764) of messages sent and 9.62% (362/3764) of text messages sent were replied to with a problem. An outcome analysis examining relationship between reply rate and VL did not meet statistical significance (P=.07), but may be worthy of investigating further in a larger study. CONCLUSIONS: WelTel may be an effective tool for improving cART adherence and reducing VLs among high-risk, vulnerable HIV-positive persons.

RESUMEN

BACKGROUND: Direct-acting antivirals (DAAs) against hepatitis C virus (HCV) have been described as revolutionary. However, it remains uncertain how effective these drugs will be for individuals coinfected with human immunodeficiency virus (HIV)-HCV. Bridging this gap between efficacy and effectiveness requires a focus on the generalizability of clinical trials. METHODS: Generalizability of DAA trials was assessed by applying the eligibility criteria from 5 efficacy trials: NCT01479868, PHOTON-1 (NCT01667731), TURQUOISE-I (NCT01939197), ION-4 (NCT02073656), and ALLY-2 (NCT02032888) that evaluated simeprevir; sofosbuvir; ombitasvir, paritaprevir/ritonavir/dasabuvir; sofosbuvir/ledipasvir; and daclatasvir/sofosbuvir, respectively, to the Canadian Coinfection Cohort, representing approximately 23% of the total coinfected population in care in Canada. RESULTS: Of 874 active participants, 70% had chronic HCV, of whom 410, 26, 94, and 11 had genotypes 1, 2, 3, and 4, respectively. After applying trial eligibility criteria, only 5.9% (24/410) would have been eligible for enrollment in the simeprevir trial, 9.8% (52/530) in PHOTON-1, 6.3% (26/410) in TURQUOISE-I, and 8.1% (34/421) in ION-4. The ALLY-2 study was more inclusive; 43% (233/541) of the cohort would have been eligible. The most exclusive eligibility criteria across all trials with the exception of ALLY-2 were restriction to specific antiretroviral therapies (63%-79%) and active illicit drug use (53%-55%). CONCLUSIONS: DAA trial results may have limited generalizability, since the majority of coinfected individuals were not eligible to participate. Exclusions appeared to be related to improving treatment outcomes by not including those at higher risk of poor adherence and reinfection--individuals for whom real-world data are urgently needed.

RESUMEN

BACKGROUND: Liver diseases progress faster in human immunodeficiency virus (HIV)-hepatitis C virus (HCV)-coinfected persons than HIV-monoinfected persons. The aim of this study was to compare rates of liver fibrosis progression (measured by the aspartate-to-platelet ratio index [APRI]) among HIV-HCV-coinfected users of modern protease inhibitor (PI)- and nonnucleoside reverse transcriptase inhibitor (NNRTI)-based regimens with a backbone of tenofovir/emtricitabine (TDF/FTC) or abacavir/lamivudine (ABC/3TC). METHODS: Data from a Canadian multicenter cohort study were analyzed, including 315 HCV polymerase chain reaction-positive persons who initiated antiretroviral therapy with a PI or NNRTI and a backbone containing either TDF/FTC or ABC/3TC. Multivariate linear regression analyses with generalized estimating equations were performed after propensity score matching to balance covariates across classes of anchor agent. RESULTS: A backbone of TDF/FTC was received by 67% of PI users and 69% of NNRTI users. Both PI and NNRTI use was associated with increases in APRI over time when paired with a backbone of ABC/3TC: 16% per 5 years (95% confidence interval [CI], 4%, 29%) and 11% per 5 years (95% CI, 2%, 20%), respectively. With TDF/FTC use, no clear association was found among PI users (8% per 5 years, 95% CI, -3%, 19%) or NNRTI users (3% per 5 years, 95% CI, -7%, 12%). CONCLUSIONS: Liver fibrosis progression was more influenced by the backbone than by the class of anchor agent in HIV-HCV-coinfected persons. Only ABC/3TC-containing regimens were associated with an increase of APRI score over time, regardless of the class of anchor agent used.

RESUMEN

OBJECTIVES: To investigate the prevalence of endocrine disturbances in a group of HIV-positive (HIV+) women and to identify factors affecting presence of these disorders. To examine specifically whether cellular ageing, as measured by leukocyte telomere length (LTL), is correlated with the presence of endocrine disturbance. DESIGN: A cross-sectional retrospective substudy of an ongoing prospective cohort study. PATIENTS: Adult HIV+ (≥19 years) women enrolled in the CARMA (Children and Women: AntiRetrovirals and Markers of Aging) cohort study (N = 192). Prevalences of T2DM, glucose intolerance, dyslipidaemia, thyroid disorders, adrenal insufficiency, hypogonadism, primary ovarian insufficiency (POI), demographics, HIV and hepatitis C virus (HCV) infection status, baseline LTL, combined antiRetroviral therapy (cART) and substance exposures were collected. Statistical analysis included univariable followed by multivariable Poisson regression and step-wise reduction to refine the multivariable model. RESULTS: Prevalence of any endocrine abnormality was 58% (dyslipidaemia 43%, glucose intolerance/T2DM 13%, thyroid disorders 15%). In multivariable analysis, age was associated with number and type (any, glucose, lipid) of abnormality, while increasing body mass index (BMI) was associated with number of diagnoses and with glucose metabolism disorders. Interestingly, peak HIV pVL ≥100 000 copies/ml was associated with any abnormality, total number of disorders and presence of a thyroid disorder, while any disorder, glucose abnormalities and dyslipidaemia were negatively associated with alcohol use. LTL was not associated with number or type of endocrine abnormalities in this study. CONCLUSION: Further studies examining the relationship between duration and extent of exposure to HIV viraemia in relation to developing abnormal endocrine function are warranted.

RESUMEN

Although major advances have occurred in treating patients with hepatitis C virus (HCV) with the development of new direct-acting antivirals (DAAs), treatment of liver transplant recipients with HCV, human immunodeficiency virus (HIV) coinfection, and renal disease is challenging due to the lack of efficacy and safety data in this population. We report a case of successful HCV therapy in a postliver transplant HIV coinfected patient, with stage 4 chronic kidney disease, using an all-oral regimen of simeprevir, sofosbuvir, and ribavirin. The 51-year-old male achieved SVR24, and no specific HIV-related or transplant-related adverse events were documented during the treatment period. The new DAAs show promise for HIV coinfected patients and those with severe to end-stage renal disease (ESRD); however, robust clinical trials or large cohort studies will need to be conducted to confirm the efficacy and safety of these newer agents in this setting.

RESUMEN

Though evidence shows that Mobile health (mHealth) interventions can improve adherence and viral load in HIV-positive persons, few have studied the health care providers' (HCP) perspective. We conducted a prospective mixed methods pilot study using the WelTel intervention wherein HIV-positive participants (n = 25) received weekly interactive text messages for 6 months. Text message response rate and topic data were collected to illustrate the HCP experience. The aim of this study is to explore intervention acceptability and feasibility from the HCP perspective through a baseline focus group and end of study interviews with HCP impacted by the intervention. Interview data were thematically coded using the Technology Acceptance Model. HCPs identified that the WelTel intervention engaged patients in building relationships, while organizing and streamlining existing mHealth efforts and dealing with privacy issues. HCPs recognized that although workload would augment initially, intervention benefits were many, and went beyond simply improving HIV viral load.
