The prevalence and correlates of biomarker positive unhealthy alcohol use among women living with and without HIV in San Francisco, California.

The objective of this study was to identify the prevalence and correlates of phosphatidylethanol (PEth) levels suggestive of unhealthy alcohol use among women living with and without HIV who self-reported no or low-risk drinking. We analyzed data from a cross-sectional study among women enrolled in the San Francisco Bay Area site of the Women's Interagency HIV Study (WIHS). Between October 2017 and March 2018, PEth was tested from dried blood spots in 192 women enrolled in the San Francisco site of the WIHS. Using multivariable logistic regression, we identified the correlates of PEth levels suggestive of unhealthy alcohol use (>50 ng/ml) among the 168 women who reported no or low-risk drinking (<7 drinks per week) in the past six months, while controlling for age in years and race/ethnicity. Among the 168 women in the analysis sample, the median age was 55; 51% identified as Black/African American, 47% were living with HIV and 28% had PEth levels ≥50 ng/ml which are suggestive of unhealthy alcohol use. Factors independently associated with PEth levels ≥50 ng/ml in adjusted models were: identifying as Black/African American (adjusted odds ratio [aOR] = 8.34, 95% CI = 2.06-33.72), having an alanine transaminase to aspartate aminotransferase ratio > 1 (aOR = 3.10, 95% CI = 1.18-8.13), higher high-density lipoprotein levels (aOR = 1.31 per 10 mg/dL increase, 95% CI = 1.01-1.70), and consuming a greater number of drinks per week in the past six months (aOR = 1.40, 95% CI = 1.10-1.78). Nearly a third of women in this study had PEth levels suggestive of unhealthy alcohol use and potentially under-reported their use. To optimize alcohol related health care, there is a need to consider approaches to improve ascertainment of unhealthy alcohol use, especially among Black/African American women and those living with liver disease, so that interventions can be initiated.

MASLD in people with HIV exhibits higher fibrosis stage despite lower disease activity than in matched controls.

BACKGROUND: Metabolic dysfunction-associated steatotic liver disease (MASLD) is common in people with HIV (PWH). The morphological spectrum of MASLD compared to matched controls and of the correlation between the NAFLD activity score (NAS) and fibrosis stage in PWH remains unknown. METHODS: Overall, 107 liver biopsies from PWH with MASLD (MASLD-PWH) were matched to 107 biopsies from individuals with MASLD and without HIV (MASLD controls) on age at biopsy, race/ethnicity, sex, type 2 diabetes, body mass index (BMI) and alanine aminotransferase (ALT) level. Biopsies were scored using NAS. RESULTS: Compared to MASLD-controls, MASLD-PWH had lower steatosis grade (OR: 0.65, 95% CI: (0.47-0.90), p = 0.01), lower lobular inflammation grade (OR: 0.55, 95% CI: (0.34-0.89), p = 0.02), less portal inflammation (OR: 0.42, 95% CI: (0.25-0.72), p = 0.002) and less ballooned hepatocytes (OR: 0.60, 95% CI: (0.41-0.88), p = 0.01). Thus, NAS was lower in MASLD-PWH (OR: 0.69, 95% CI: (0.56-0.85), p < 0.001) than in MASLD controls. There was a trend towards lower prevalence of steatohepatitis in MASLD-PWH (OR: 0.84, 95% CI: (0.68-1.03), p = 0.09). A multivariate analysis demonstrated that MASLD-PWH cases had significantly less steatosis (OR: 0.66, p = 0.03), portal inflammation (OR: 0.34, p = 0.001) and ballooned hepatocytes (OR: 0.55, p = 0.01), yet higher stage fibrosis (OR: 1.42, p = 0.03) compared to MASLD controls. CONCLUSION: The NAS and histological drivers of fibrosis (e.g. inflammation and hepatocyte ballooning) are less pronounced in MASLD-PWH, and yet fibrosis stage was generally higher when compared to matched controls with MASLD without HIV. This suggests HIV-specific factors beyond hepatic necroinflammation may contribute to fibrosis progression in MASLD-PWH.

Relationships Between Hepatic Steatosis and Frailty Differ by HIV Serostatus.

BACKGROUND: Frailty is associated with obesity-related comorbidities, but the relationship with nonalcoholic fatty liver disease (NAFLD) in people with HIV has been incompletely described. Our objective was to assess the associations between NAFLD and frailty. METHODS: Cross-sectional and longitudinal analysis of men in the Multicenter AIDS Cohort Study. NAFLD was defined as a liver/spleen ratio <1.0 on abdominal computed tomography scans; frailty was defined by the frailty phenotype as having 3 of the following: weakness, slowness, weight loss, exhaustion, and low physical activity. RESULTS: Men without (n = 200) and with HIV (n = 292) were included. NAFLD prevalence was 21% vs 16% and frailty 12% vs 17%, respectively. Among men with NAFLD, frailty was more prevalent in men without HIV (21% vs 11%). In multivariate analysis, NAFLD was significantly associated with frailty after controlling for significant variables. Men without HIV and NAFLD had 2.6 times higher probability [95% confidence interval (CI): 1.2- to 5.7] of frailty relative to men with neither HIV nor NAFLD. This association was not seen in men with HIV. The probability of frailty was higher among men without HIV with NAFLD (27% vs 10% in men without NAFLD) but lower among men with HIV with NAFLD (14% vs 19% in men without NAFLD). No significant relationships were found in longitudinal analyses. CONCLUSIONS: NAFLD was independently associated with frailty among men without HIV but not men with HIV, despite increased prevalence of frailty among men with HIV. The mechanisms of the muscle-liver-adipose tissue axis underlying NAFLD might differ by HIV serostatus.

Best practices for hepatitis C linkage to care in pregnant and postpartum women: perspectives from the Treatment In Pregnancy for Hepatitis C Community of Practice.

There is an increasing burden of hepatitis C virus among persons of reproductive age, including pregnant and breastfeeding women, in many regions worldwide. Routine health services during pregnancy present a critical window of opportunity to diagnose and link women with hepatitis C virus infection for care and treatment to decrease hepatitis C virus-related morbidity and early mortality. Effective treatment of hepatitis C virus infection in women diagnosed during pregnancy also prevents hepatitis C virus-related adverse events in pregnancy and hepatitis C virus vertical transmission in future pregnancies. However, linkage to care and treatment for women diagnosed in pregnancy remains insufficient. Currently, there are no best practice recommendations from professional societies to ensure appropriate peripartum linkage to hepatitis C virus care and treatment. We convened a virtual Community of Practice to understand key challenges to the hepatitis C virus care cascade for women diagnosed with hepatitis C virus in pregnancy, highlight published models of integrated hepatitis C virus services for pregnant and postpartum women, and preview upcoming research and programmatic initiatives to improve linkage to hepatitis C virus care for this population. Four-hundred seventy-three participants from 43 countries participated in the Community of Practice, including a diverse range of practitioners from public health, primary care, and clinical specialties. The Community of Practice included panel sessions with representatives from major professional societies in obstetrics/gynecology, maternal fetal medicine, addiction medicine, hepatology, and infectious diseases. From this Community of Practice, we provide a series of best practices to improve linkage to hepatitis C virus treatment for pregnant and postpartum women, including specific interventions to enhance colocation of services, treatment by nonspecialist providers, active engagement and patient navigation, and decreasing time to hepatitis C virus treatment initiation. The Community of Practice aims to further support antenatal providers in improving linkage to care by producing and disseminating detailed operational guidance and recommendations and supporting operational research on models for linkage and treatment. Additionally, the Community of Practice may be leveraged to build training materials and toolkits for antenatal providers, convene experts to formalize operational recommendations, and conduct surveys to understand needs of antenatal providers. Such actions are required to ensure equitable access to hepatitis C virus treatment for women diagnosed with hepatitis C virus in pregnancy and urgently needed to achieve the ambitious targets for hepatitis C virus elimination by 2030.

Use of HBsAg-positive donors in liver transplantation: An ILTS-EASL-AASLD multisociety survey.

The gap between organ supply and demand in liver transplantation remains large in most parts of the world. One strategy to increase the donor pool is to use grafts infected with HCV, HBV, and/or HIV viruses. We aimed to explore the current use of HBsAg-positive liver grafts worldwide. A prospective cross-sectional web-based survey was designed, with a total of 28 queries, assessing national and local regulations, center experience, and center-specific experience related to the topic, and sent to all members of International Liver Transplantation Society, European Association for the Study of the Liver, and American Association for the Study of the Liver, and promoted on social media. A total of 135 liver transplant centers answered the survey: 38% from WHO European Regions, 39% from American regions, and 9.7% from South-East Asian regions. Most of the participating centers (67.3%) had been performing liver transplantation for over 15 years, with a mean of 66.5 liver transplants per year, and 54% also performed living-donor liver transplants. HBV-related disease was the indication for liver transplantation in an average of 15% of all liver transplantation cases. Regarding national and/or regional regulations, 40% of the centers reported that the use of HBsAg-positive donors was permitted, and an additional 20% could use them under special circumstances. Thirty-two centers (31%) had previously used HBsAg-positive donors. Among these centers, 62.5% conducted living-donor liver transplants and showed an increased inclination toward the use of HBsAg-positive grafts in centers with elevated waitlist mortality. HBsAg-positive donors are underutilized worldwide. The use of HBsAg-positive liver grafts could help to increase the donor pool, particularly in highly endemic areas.

Microbial Translocation and Gut Damage Are Associated With an Elevated Fast Score in Women Living With and Without HIV.

Background: Steatohepatitis is common in persons living with HIV and may be associated with gut microbial translocation (MT). However, few studies have evaluated the gut-liver axis in persons living with HIV. In the Women's Interagency HIV Study, we examined the associations of HIV and circulating biomarkers linked to MT and gut damage using the FibroScan-aspartate aminotransferase (FAST) score, a noninvasive surrogate for steatohepatitis with advanced fibrosis. Methods: Among 883 women with HIV and 354 without HIV, we used multivariable regression to examine the associations of HIV and serum biomarkers linked to MT and gut damage (kynurenine and tryptophan ratio, intestinal fatty acid-binding protein, soluble CD14, and soluble CD163) with a log-transformed FAST score after adjusting for key covariates. We used a path analysis and mediation models to determine the mediating effect of each biomarker on the association of HIV with FAST. Results: HIV infection was associated with a 49% higher FAST score. MT biomarker levels were higher in women with HIV than women without HIV (P < .001 for each). MT biomarkers mediated 13% to 32% of the association of HIV and FAST score. Conclusions: Biomarkers linked to MT and gut damage are associated with a higher FAST score and mediate the association of HIV with a higher FAST score. Our findings suggest that MT may be an important mechanism by which HIV increases the risk of steatohepatitis with advanced fibrosis.

Staff-Facilitated Telemedicine Care Delivery for Treatment of Hepatitis C Infection among People Who Inject Drugs.

BACKGROUND: Telemedicine offers the opportunity to provide clinical services remotely, thereby bridging geographic distances for people engaged in the medical system. Following the COVID-19 pandemic, the widespread adoption of telemedicine in clinical practices has persisted, highlighting its continued relevance for post-pandemic healthcare. Little is known about telemedicine use among people from socially marginalized groups. METHODS: The No One Waits (NOW) Study is a single-arm clinical trial measuring the acceptability, feasibility, and safety of an urban point-of-diagnosis hepatitis C (HCV) treatment initiation model delivered in a non-clinical community setting. Participants enrolled in the NOW Study are recruited via street outreach targeting people experiencing homelessness and injecting drugs. Throughout the NOW Study, clinical care is delivered through a novel staff-facilitated telemedicine model that not only addresses geographic and transportation barriers, but also technology and medical mistrust, barriers often unique to this population. While clinicians provide high-quality specialty practice-based care via telemedicine, on-site staff provide technical support, aid in communication and rapport, and review the clinicians' instructions and next steps with participants following the visits. Research questionnaires collect information on participants' experience with and perceptions of telemedicine (a) prior to treatment initiation and (b) at treatment completion. DISCUSSION: For people from socially marginalized groups with HCV infection, creative person-centered care approaches are necessary to diagnose, treat, and cure HCV. Although non-clinical, community-based staff-facilitated telemedicine requires additional resources compared to standard-of-care telemedicine, it could expand the reach and offer a valuable entrance into technology-delivered care for socially marginalized groups. TRIAL REGISTRATION: NCT03987503.

Screening for social determinants of health among populations at risk for MASLD: a scoping review.

Background: Social determinants of health (SDoH) have been associated with disparate outcomes among those with metabolic dysfunction-associated steatotic liver disease (MASLD) and its risk factors. To address SDoH among this population, real-time SDoH screening in clinical settings is required, yet optimal screening methods are unclear. We performed a scoping review to describe the current literature on SDoH screening conducted in the clinical setting among individuals with MASLD and MASLD risk factors. Methods: Through a systematic literature search of MEDLINE, Embase, and CINAHL Complete databases through 7/2023, we identified studies with clinic-based SDoH screening among individuals with or at risk for MASLD that reported pertinent clinical outcomes including change in MASLD risk factors like diabetes and hypertension. Results: Ten studies (8 manuscripts, 2 abstracts) met inclusion criteria involving 148,151 patients: 89,408 with diabetes and 25,539 with hypertension. Screening was primarily completed in primary care clinics, and a variety of screening tools were used. The most commonly collected SDoH were financial stability, healthcare access, food insecurity and transportation. Associations between clinical outcomes and SDoH varied; overall, higher SDoH burden was associated with poorer outcomes including elevated blood pressure and hemoglobin A1c. Conclusion: Despite numerous epidemiologic studies showing associations between clinical outcomes and SDoH, and guidelines recommending SDoH screening, few studies describe in-clinic SDoH screening among individuals with MASLD risk factors and none among patients with MASLD. Future research should prioritize real-time, comprehensive assessments of SDoH, particularly among patients at risk for and with MASLD, to mitigate disease progression and reduce MASLD health disparities.

Effects of Food Insecurity on Hepatic Steatosis and Fibrosis in People With HIV.

BACKGROUND & AIMS: Food insecurity (FI) is a risk factor for nonalcoholic fatty liver disease (NAFLD) and advanced fibrosis in the general population, but its impact on liver disease in people with HIV (PWH) is unknown. METHODS: We examined the association of FI with prevalence of NAFLD and fibrosis in a diverse cohort of PWH. PWH aged ≥ 18 years on antiretroviral therapy, HIV RNA <200 copies/mL, and without other known liver diseases were screened for NAFLD (controlled attenuated parameter ≥263 decibels/meter) and advanced fibrosis (liver stiffness measurement ≥11 kilopascals) by vibration controlled transient elastography at 8 U.S. CENTERS: Participants were categorized as food insecure using the Six-Item Short Form Household Food Security Survey. We used multivariable logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (CIs) of NAFLD and advanced fibrosis by FI status. RESULTS: Among 654 PWH, NAFLD was present in 348 (53%) and advanced fibrosis in 41 (6%). FI was present in 203 of participants (31%), including 97/348 with NAFLD (28%) and 18/41 with advanced fibrosis (44%). In multivariable analysis, FI was associated with lower odds of NAFLD (OR, 0.57; 95% CI, 0.37-0.88) and a greater, but nonsignificant, odds of advanced fibrosis (OR, 1.38; 95% CI, 0.65-2.90). We identified a significant interaction between FI and diabetes (P = .02) on fibrosis risk, with greater odds of fibrosis among food insecure PWH and diabetes (OR, 3.83; 95% CI, 1.15-12.73) but not among food insecure nondiabetics (OR, 1.12; 95% CI, 0.47-2.98). CONCLUSIONS: FI is highly prevalent among PWH and associated with lower odds of NAFLD, and among PWH with diabetes, there is greater odds of advanced fibrosis. FI may contribute to hepatic fibrosis through mechanisms other than steatosis in PWH.

Food insecurity is a risk factor for metabolic dysfunction-associated steatotic liver disease in Latinx children.

INTRODUCTION: Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common chronic liver disease among US children. Studies have associated food insecurity with MASLD in adults, but there are few studies of pediatric MASLD, particularly in high-risk populations. We assessed the impact of household food insecurity at 4 years of age on MASLD in Latinx children. METHODS: Using a prospective cohort design, Latina mothers were recruited during pregnancy and followed with their children until early to mid-childhood. Our primary exposure was household food insecurity at 4 years of age measured using the validated US Household Food Security Food Module. Our primary outcome, MASLD, was defined as alanine transaminase (ALT) ≥95th% for age/gender plus body mass index (BMI) ≥85% at time of ALT measurement (assessed between ages 5-12). We used multivariable logistic regression models to test for independent associations between household food insecurity and pediatric MASLD. RESULTS: Among 136 children, 28.7% reported household food insecurity at 4 years of age and 27.2% had MASLD in early to middle childhood. Approximately 49% of children with MASLD and 21% of children without MASLD were food insecure (p < 0.01). Exposure to household food insecurity at age 4 was independently associated with a 3.7-fold higher odds of MASLD later in childhood (95% CI: 1.5-9.0, p < 0.01). CONCLUSIONS: Exposure to household food insecurity at 4 years of age was associated with increased risk for MASLD later in childhood. Further studies are needed to explore mechanism(s) and impact of reducing food insecurity on risk for MASLD.

Oleic acid triggers burial behavior in a termite population through an odorant binding protein.

Social insects maintain hygienic conditions through their social immunity behaviors. Among these behaviors, burial behavior of termites is central for protecting healthy individuals from corpses. Many factors trigger burial behavior, and it is generally believed that chemicals released by corpses, such as oleic acid, are the most important cues for triggering burial behavior in termites. However, the contribution of the olfactory system to this behavior remains unclear. Here we report an odorant binding protein (OBP) that transports oleic acid and triggers burial behavior in Coptotermes formosanus Shiraki. We demonstrated that CforOBP7 is highly expressed in the antennae of workers. Fluorescent competition binding experiments exhibited that CforOBP7 has a strong affinity for oleic acid. Furthermore, the antennal response to oleic acid was significantly reduced, and oleic acid-triggered burial behavior was also inhibited in CforOBP7-silenced termites. We conclude that CforOBP7 governs the burial behavior of C. formosanus triggered by oleic acid.

Diagnostic Ability of Simple Noninvasive Blood Tests to Predict Increased Liver Stiffness in People Living With HIV and Steatotic Liver Disease.

INTRODUCTION: Steatotic liver disease is common in people with HIV (PWH). Identifying those with advanced fibrosis (AF, bridging fibrosis or cirrhosis), F3-4, is important. We aimed to examine the performance of FIB-4 and nonalcoholic fatty liver disease (NAFLD) fibrosis score (NFS) in PWH to identify those with AF assessed by liver stiffness measurement (LSM). METHODS: We prospectively collected data on adults participating in 2 National Institute of Health-sponsored HIV NAFLD networks. All had HIV on antiretroviral therapy (ART) ≥6 months with HIV RNA <200 copies/mL. Those with viral hepatitis, other liver disease, excessive alcohol use, or hepatic decompensation were excluded. Vibration-controlled transient elastrography for LSM was performed, and AF defined as ≥11 kPa was compared with FIB-4 and NFS at predefined thresholds (<1.3 and >2.67 for FIB-4 and <-1.455 and >0.675 for NFS). RESULTS: A total of 1,065 participants were analyzed: mean age 51.6 years, 74% male, 28% White, 46% Black, 22% Hispanic, with 34% overweight (body mass index 25-29 kg/m 2 ) and 43% obese (body mass index ≥30 kg/m 2 ). Features of the metabolic syndrome were common: hyperlipidemia 35%, type 2 diabetes 17%, and hypertension 48%. The median CD4 + T-cell count was 666 cells/mm 3 , 74% had undetectable HIV RNA, and duration of HIV-1 was 17 years with most taking a nucleoside reverse transcriptase inhibitor (92%) and an integrase inhibitor (83%). The mean LSM was 6.3 kPa, and 6.3% had AF. The area under the receiver characteristic curve for FIB-4 and NFS to identify AF were 0.70 and 0.75, respectively. While both had high negative predictive values (97%-98%), the sensitivity at low thresholds and specificity at high thresholds were 64% and 97% for FIB-4 and 80% and 96% for NFS, respectively. Neither FIB-4 nor NFS at either threshold had good positive predictive value to detect AF. DISCUSSION: FIB-4 and NFS have excellent specificity and negative predictive value for detecting AF, and thus can be used as screening tools in PWH to exclude those with AF who do not need further testing (LSM) or referral to hepatologist.

Association of Androgen Hormones, Sex Hormone-Binding Globulin, and the Menopausal Transition With Incident Diabetes Mellitus in Women With and Without HIV.

BACKGROUND: HIV is associated with alterations in androgen hormone levels and sex hormone-binding globulin (SHBG) in women. Higher SHBG has been associated with a lower risk of diabetes in the general population, but the contribution of HIV, androgen hormones, SHBG, and menopausal phase to diabetes is unclear. METHODS: From April 2003 through February 2020, 896 women with HIV (WWH) and 343 women without HIV (WWOH) from the Women's Interagency HIV Study with morning total testosterone, dehydroepiandrosterone sulfate (DHEAS), and SHBG levels were followed to assess for incident diabetes. Parametric regression models were used with age as the time scale and relative times (RT) as the measure of association of hormone level and menopausal phase with incident diabetes. Analyses incorporated time-dependent androgen hormone, SHBG levels, and menopausal phase and were adjusted for race/ethnicity, enrollment year, smoking status, BMI, hepatitis C virus status, and HIV-related factors. RESULTS: In total, 128 (14%) WWH and 47 (14%) WWOH developed diabetes. In WWH, a doubling of SHBG and DHEAS were associated with a 7% (RT = 1.07 [95% CI: 0.82 to 1.40] and 15% (RT = 1.15 [95% CI: 0.95 to 1.39]) longer time to diabetes, respectively; in WWOH, a doubling of SHBG and DHEAS were associated with 84% (RT = 1.84 [95% CI: 0.89 to 3.82]) and 41% (RT= 1.41 [95% CI: 0.82 to 2.44]) longer times to diabetes. Total testosterone was not associated. In WWH, later menopausal phase was associated with shorter times to diabetes. CONCLUSIONS: Despite alterations in androgen hormone and SHBG levels in HIV, regardless of HIV status, higher SHBG and DHEAS were associated with nonstatistically significant slower progression to diabetes. The menopausal transition may be a better hormonal indicator of diabetes risk in WWH.

High prevalence of hepatitis B virus susceptibility among persons undergoing community-based hepatitis C virus treatment.

BACKGROUND: Due to shared modes of transmission, coinfection with hepatitis B virus (HBV) and hepatitis C virus (HCV) is common, and HBV vaccination is recommended for all persons with HCV who remain susceptible to HBV. To identify potential gaps in HBV vaccination among this high-risk population, we aimed to determine the patterns of HBV susceptibility in persons undergoing community-based HCV treatment. METHODS: We performed a cross-sectional study within two community-based HCV treatment programs in an urban US setting. Participants were identified for HCV screening and confirmatory testing via street-outreach recruitment directed at persons experiencing homelessness and currently using drugs. Participants were excluded if HBsAg was reactive. Cohort characteristics were obtained via intake surveys and descriptive analysis was performed by exposure status. RESULTS: Among 150 participants without chronic HBV receiving community-based HCV treatment, 43% had evidence of prior HBV infection, 26% were immune from vaccination, and 31% were non-immune. Among the subset of the cohort reporting current injection drug use (IDU) (N = 100), 31% (n = 10) of those aged 24-40 and 47% (n = 23) of those aged 41-57 remained susceptible to HBV infection. By contrast only two participants aged 58-74 were HBV non-immune (11%), with 84% immune due to prior exposure. CONCLUSIONS: Our data reflect a high prevalence of HBV susceptibility among persons undergoing community-based HCV treatment. Although younger patients were more likely to be immune due to vaccination, a high proportion remained non-immune to HBV, particularly among those reporting current IDU. Our data reflect a gap in HBV vaccination among younger persons with HCV and suggest a potential role for co-localizing HBV vaccination with community-based HCV screening and treatment.

Pivoting from in-person to phone survey assessment of alcohol and substance use: effects on representativeness in a United States prospective cohort of women living with and without HIV.

Background: Many clinical and population-based research studies pivoted from in-person assessments to phone-based surveys due to the COVID-19 pandemic. The impact of these transitions on survey response remains understudied, especially for people living with HIV. Given that there are gender-specific trends in alcohol and substance use, it is particularly important to capture these data for women.Objective: Identify factors associated with responding to an alcohol and substance use phone survey administered during the COVID-19 pandemic in the Women's Interagency HIV Study, a multicenter US prospective cohort of women living with and without HIV.Methods: We used multivariable logistic regression to assess for associations of pre-pandemic (April-September 2019) sociodemographic factors, HIV status, housing status, depressive symptoms, alcohol use, and substance use with response to an early-pandemic (August-September 2020) phone survey.Results: Of 1,847 women who attended an in-person visit in 2019, 78% responded to a phone survey during the pandemic. The odds of responding were lower for women of Hispanic ethnicity (aOR 0.47 95% CI 0.33-0.66, ref=Black/African American) and those who reported substance use (aOR 0.63 95% CI 0.41-0.98). By contrast, the odds were higher for White women (aOR 1.64 95% CI 1.02-2.70, ref=Black/African American) and those with stable housing (aOR 1.74 95% CI 1.24-2.43).Conclusions: Pivoting from an in-person to phone-administered alcohol and substance use survey may lead to underrepresentation of key subpopulations of women who are often neglected in substance use and HIV research. As remote survey methods become more common, investigators need to ensure that the study population is representative of the target population.

Prevalence of steatotic liver disease, MASLD, MetALD and significant fibrosis in people with HIV in the United States.

BACKGROUND: Metabolic dysfunction-associated steatotic liver disease (MASLD) has recently been proposed as a replacement term for NAFLD. AIMS: To assess the effects of this new nomenclature on the prevalence and distribution of different SLD categories in people with HIV (PWH) and identified factors associated with MASLD and clinically significant fibrosis (CSF). METHODS: PWH were prospectively enrolled from 9 US centres and underwent clinical evaluation and vibration-controlled transient elastography for controlled attenuation parameter (CAP) and liver stiffness measurement (LSM). SLD was defined as CAP ≥ 263 dB/m, CSF as LSM of ≥8 kPa, and advanced fibrosis (AF) as LSM ≥ 12 kPa. The prevalence of SLD, MASLD, metabolic dysfunction and alcohol-associated liver disease (MetALD), ALD, cryptogenic (cSLD), CSF and AF were determined. Uni- and multivariate logistic regression models were used to assess factors associated with MASLD and CSF risk. RESULTS: Of 1065 participants, 74% were male, mean (SD) age 51.6 ± 11.9 years, 46% non-Hispanic Black and 74% with undetectable HIV RNA. The prevalence of SLD was 52%, MASLD 39%, MetALD 10%, ALD 3%, CSF 15% and AF 4%. Only 0.6% had cSLD. Black race was protective whereas obesity, ALT and AST levels were associated with increased risk of MASLD and CSF in MASLD. HIV or antiretroviral therapy did not affect MASLD risk. CONCLUSIONS: MASLD and MetALD are the dominant causes of SLD in PWH, affecting almost half. Application of the new nomenclature resulted in minimal change in the proportion of patients with MASLD who would have been diagnosed previously with NAFLD.
