Cluster of Nontoxigenic Corynebacterium diphtheriae Infective Endocarditis and Rising Background C. diphtheriae Cases-Seattle, Washington, 2020-2023.

BACKGROUND: Nontoxigenic Corynebacterium diphtheriae, often associated with wounds, can rarely cause infective endocarditis (IE). Five patients with C. diphtheriae IE were identified within 12 months at a Seattle-based hospital system. We reviewed prior C. diphtheriae-positive cultures to determine if detections had increased over time and evaluated epidemiologic trends. METHODS: We conducted a formal electronic health record search to identify all patients aged ≥18 years with C. diphtheriae detected in a clinical specimen (ie, wound, blood, sputum) between 1 September 2020 and 1 April 2023. We collected patient demographics, housing status, comorbidities, substance-use history, and level of medical care required at detection. We extracted laboratory data on susceptibilities of C. diphtheriae isolates and on other pathogens detected at the time of C. diphtheriae identification. RESULTS: Between 1 September 2020 and 1 April 2023, 44 patients (median age, 44 years) had a C. diphtheriae-positive clinical culture, with most detections occurring after March 2022. Patients were predominantly male (75%), White (66%), unstably housed (77%), and had a lifetime history of injecting drugs (75%). Most C. diphtheriae-positive cultures were polymicrobial, including wound cultures from 36 (82%) patients and blood cultures from 6 (14%) patients, not mutually exclusive. Thirty-four patients (77%), including all 5 patients with C. diphtheriae IE, required hospital admission for C. diphtheriae or a related condition. Of the 5 patients with IE, 3 died of IE and 1 from COVID-19. CONCLUSIONS: Findings suggest a high-morbidity outbreak disproportionately affecting patients who use substances and are unstably housed.

Prevalence and determinants of hepatitis delta virus infection among HIV/hepatitis B-coinfected adults in care in the United States.

Hepatitis delta virus (HDV) infection increases the risk of liver complications compared to hepatitis B virus (HBV) alone, particularly among persons with human immunodeficiency virus (HIV). However, no studies have evaluated the prevalence or determinants of HDV infection among people with HIV/HBV in the US. We performed a cross-sectional study among adults with HIV/HBV coinfection receiving care at eight sites within the Center for AIDS Research Network of Integrated Clinical Systems (CNICS) between 1996 and 2019. Among patients with available serum/plasma specimens, we selected the first specimen on or after their initial HBV qualifying test. All samples were tested for HDV IgG antibody and HDV RNA. Multivariable log-binomial generalized linear models were used to estimate prevalence ratios (PRs) with 95% CIs of HDV IgG antibody-positivity associated with determinants of interest (age, injection drug use [IDU], high-risk sexual behaviour). Among 597 adults with HIV/HBV coinfection in CNICS and available serum/plasma samples (median age, 43 years; 89.9% male; 52.8% Black; 42.4% White), 24/597 (4.0%; 95% CI, 2.4%-5.6%) were HDV IgG antibody-positive, and 10/596 (1.7%; 95% CI, 0.6%-2.7%) had detectable HDV RNA. In multivariable analysis, IDU was associated with exposure to HDV infection (adjusted PR = 2.50; 95% CI, 1.09-5.74). In conclusion, among a sample of adults with HIV/HBV coinfection in care in the US, 4.0% were HDV IgG antibody-positive, among whom 41.7% had detectable HDV RNA. History of IDU was associated with exposure to HDV infection. These findings emphasize the importance of HDV testing among persons with HIV/HBV coinfection, especially those with a history of IDU.

Strategies for Hepatitis B Virus Prevention in People Living with HIV.

PURPOSE OF REVIEW: Coinfection with HIV and hepatitis B virus (HBV) is common owing to shared routes of transmission, and persons with HIV-HBV coinfection experience an accelerated progression of liver disease. Despite the widespread availability of HBV vaccination, rates of seroprotection in people living with HIV (PLWH) have historically been low. In this article, we review strategies in HBV prevention among PLWH, focusing specifically on updates in HBV vaccination and chemoprophylaxis. RECENT FINDINGS: Vaccination remains the hallmark of HBV prevention, and recent studies suggest that a double dose of HBV vaccine and Heplisav-B can improve rates of seroprotection among PLWH. The use of tenofovir-containing antiretroviral therapy (ART) has similarly been shown to provide some HBV protection in PLWH; however, this protection can be lost when switching to newer tenofovir-sparing regimens, including long-acting injectables. All HBV-susceptible persons with HIV should be vaccinated against HBV, regardless of ART regimen and CD4 count.

Hepatitis C coinfection and extrahepatic cancer incidence among people living with HIV.

OBJECTIVES: We assessed the incidence of extrahepatic cancer among people with HIV/HCV coinfection and the potential impact of direct-acting antivirals (DAAs) on extrahepatic cancer risk among people with HIV/HCV coinfection. DESIGN: Our study cohort included adults who initiated HIV care at a CNICS site in the US during 1995-2017, excluding those with previous cancer and without HCV testing. METHODS: We used Cox regression to estimate hazard ratios for extrahepatic cancer incidence among patients with HIV/HCV coinfection compared with those with HIV monoinfection. Standardized morbidity ratio (SMR) weights were used to create a 'pseudopopulation' in which all patients were treated with antiretroviral therapy (ART), and to compare extrahepatic cancer incidence among patients with untreated HIV/HCV coinfection with the incidence that would have been observed if they had been successfully treated for HCV. RESULTS: Of 18 422 adults, 1775 (10%) had HCV RNA and 10 899 (59%) were on ART at baseline. Incidence rates of any extrahepatic cancer among patients with HIV/HCV coinfection and HIV monoinfection were 1027 and 771 per 100 000 person-years, respectively. In SMR-weighted analyses, the risk of any extrahepatic cancer among patients with untreated HCV coinfection at baseline was similar to the risk if they had been successfully treated for HCV. Patients with untreated HCV coinfection at baseline had higher incidence of kidney, lung and inflammation-related cancers than if their HCV had been successfully treated, but these associations were not statistically significant. CONCLUSIONS: We did not find evidence that treating HCV coinfection with DAAs would reduce the incidence of extrahepatic cancers among people with HIV receiving ART.

Risk of HCC With Hepatitis B Viremia Among HIV/HBV-Coinfected Persons in North America.

BACKGROUND AND AIMS: Chronic HBV is the predominant cause of HCC worldwide. Although HBV coinfection is common in HIV, the determinants of HCC in HIV/HBV coinfection are poorly characterized. We examined the predictors of HCC in a multicohort study of individuals coinfected with HIV/HBV. APPROACH AND RESULTS: We included persons coinfected with HIV/HBV within 22 cohorts of the North American AIDS Cohort Collaboration on Research and Design (1995-2016). First occurrence of HCC was verified by medical record review and/or cancer registry. We used multivariable Cox regression to determine adjusted HRs (aHRs [95% CIs]) of factors assessed at cohort entry (age, sex, race, body mass index), ever during observation (heavy alcohol use, HCV), or time-updated (HIV RNA, CD4+ percentage, diabetes mellitus, HBV DNA). Among 8,354 individuals coinfected with HIV/HBV (median age, 43 years; 93% male; 52.4% non-White), 115 HCC cases were diagnosed over 65,392 person-years (incidence rate, 1.8 [95% CI, 1.5-2.1] events/1,000 person-years). Risk factors for HCC included age 40-49 years (aHR, 1.97 [1.22-3.17]), age ≥50 years (aHR, 2.55 [1.49-4.35]), HCV coinfection (aHR, 1.61 [1.07-2.40]), and heavy alcohol use (aHR, 1.52 [1.04-2.23]), while time-updated HIV RNA >500 copies/mL (aHR, 0.90 [0.56-1.43]) and time-updated CD4+ percentage <14% (aHR, 1.03 [0.56-1.90]) were not. The risk of HCC was increased with time-updated HBV DNA >200 IU/mL (aHR, 2.22 [1.42-3.47]) and was higher with each 1.0 log10 IU/mL increase in time-updated HBV DNA (aHR, 1.18 [1.05-1.34]). HBV suppression with HBV-active antiretroviral therapy (ART) for ≥1 year significantly reduced HCC risk (aHR, 0.42 [0.24-0.73]). CONCLUSION: Individuals coinfected with HIV/HBV on ART with detectable HBV viremia remain at risk for HCC. To gain maximal benefit from ART for HCC prevention, sustained HBV suppression is necessary.

Do contemporary antiretrovirals increase the risk of end-stage liver disease? Signals from patients starting therapy in the North American AIDS Cohort Collaboration on Research and Design.

PURPOSE: Despite effective antiretroviral therapy, rates of end-stage liver disease (ESLD) remain high. It is not clear whether contemporary antiretrovirals contribute to the risk of ESLD. METHODS: We included patients from cohorts with validated ESLD data in the North American AIDS Cohort Collaboration on Research and Design. Patients had to initiate antiretroviral therapy after 1 January 2004 with a nucleos(t)ide backbone of either abacavir/lamivudine or tenofovir/emtricitabine and a contemporary third (anchor) drug. Patients were followed until a first ESLD event, death, end of a cohort's ESLD validation period, loss to follow-up or 31 December 2015. We estimated associations between cumulative exposure to each drug and ESLD using a hierarchical Bayesian survival model with weakly informative prior distributions. RESULTS: Among 10 564 patients included from 12 cohorts, 62 had an ESLD event. Of the nine anchor drugs, boosted protease inhibitors atazanavir and darunavir had the strongest signals for ESLD, with increasing hazard ratios (HR) and narrowing credible intervals (CrI), from a prior HR of 1.5 (95% CrI 0.32-7.1) per 5 year's exposure to posterior HRs respectively of 1.8 (95% CrI 0.82-3.9) and 2.0 (95% CrI 0.86-4.7). Both backbones and efavirenz showed no signal. Hepatitis C coinfection was the most important covariate risk factor (HR 4.4, 95% CrI 2.6-7.0). CONCLUSIONS: While contemporary antiretrovirals pose less risk for ESLD than hepatitis coinfection, atazanavir and darunavir had a toxicity signal. We show how hierarchical Bayesian modelling can be used to detect toxicity signals in cohort event monitoring data even with complex treatments and few events.

Adherence to chronic hepatitis B screening guidelines for persons from intermediate to high prevalence Countries.

The adherence to the CDC guideline on screening non-U.S. born persons for hepatitis B virus infection was assessed. A retrospective cohort study was conducted at University of Washington primary care clinics using the electronic medical records. Persons from hepatitis B virus prevalent countries were identified using country of origin and language. Of 2329 eligible for screening, only 617 (26.5%) were screened. The prevalence of HBsAg was 35 (5.7%). Among women of reproductive age (18-44 years, n = 906), 238 (26.3%) were screened, and 7 (2.9%) were HBsAg positive. Low screening practice for chronic hepatitis B infection, and high infection prevalence among those screened was noted. The findings indicate that potentially three out of every one detected case may be missed. Urgent efforts are needed to scale up and consistently implement HBV screening at primary care clinics.

Cervical cancer screening, abnormal results, and follow-up in women with substance use-related diagnoses.

Background: Substance use-related diagnoses are common and associated with poor health outcomes. The objective of this analysis was to compare rates of cervical cancer screening, screening abnormalities, and follow-up care in women with and without a substance use-related diagnosis seen for primary care between January 1, 2016 and December 31, 2019 in the University of Washington healthcare system. Methods: This study included women aged 21-65 years of age who had at least one outpatient visit between January 1, 2016 and December 31, 2019 within one of 45 primary care or women's health clinics in the academic healthcare system. Exposure status was defined using ICD10 codes for substance-use related diagnoses or no substance-use related diagnoses. Only first cervical cancer screening was included. Generalized linear models with a binomial family and log link were used to estimate risk ratios. Results: 3845 women had a substance use-related diagnosis and 89214 did not. Women with a substance use-related diagnosis were less likely to be screened for cervical cancer (44%, 1675/3845) compared to women without a substance use-related diagnosis (49%, 43338/89214; relative risk [RR] 0.90, 95% CI 0.86-0.93). Women with a substance use-related diagnosis were also more likely to have an abnormal screening result (18%, 304/1675) compared to women without a substance use-related diagnosis (10%, 4528/43338; RR 1.74, 95% CI 1.56-1.93). Follow-up for abnormal screens did not differ significantly between groups (24 vs 25%; RR 0.80, 95% CI 0.55-1.17). Conclusion: To combat disparities in cervical cancer screening for women with substance use-related diagnoses, public health efforts should expand access to screening where women with substance use-related diagnoses are seen, including acute care, inpatient hospitalizations, and addiction treatment settings.

Postprescription Review With Threat of Infectious Disease Consultation and Sustained Reduction in Meropenem Use Over Four Years.

BACKGROUND: Following a meropenem shortage, we implemented a postprescription review with feedback (PPRF) in November 2015 with mandatory infectious disease (ID) consultation for all meropenem and imipenem courses > 72 hours. Providers were made aware of the policy via an electronic alert at the time of ordering. METHODS: A retrospective study was conducted at the University of Washington Medical Center (UWMC) and Harborview Medical Center (HMC) to evaluate the impact of the policy on antimicrobial consumption and clinical outcomes pre- and postintervention during a 6-year period. Antimicrobial use was tracked using days of therapy (DOT) per 1000 patient-days, and data were analyzed by an interrupted time series. RESULTS: There were 4066 and 2552 patients in the pre- and postintervention periods, respectively. Meropenem and imipenem use remained steady until the intervention, when a marked reduction in DOT/1000 patient-days occurred at both hospitals (UWMC: percentage change -72.1% (95% confidence interval [CI] -76.6, -66.9), P < .001; HMC: percentage change -43.6% (95% CI -59.9, -20.7), P = .001). Notably, although the intervention did not address antibiotic use until 72 hours after initiation, there was a significant decline in meropenem and imipenem initiation ("first starts") in the postintervention period, with a 64.9% reduction (95% CI 58.7, 70.2; P < .001) at UWMC and 44.7% reduction (95% CI 28.1, 57.4; P < .001) at HMC. CONCLUSIONS: PPRF and mandatory ID consultation for meropenem and imipenem use beyond 72 hours resulted in a significant and sustained reduction in the use of these antibiotics and notably impacted their up-front usage.

Sustained Sobriety: A Qualitative Study of Persons with HIV and Chronic Hepatitis C Coinfection and a History of Problematic Drinking.

For persons diagnosed with HIV and who are coinfected with hepatitis C virus (HCV), chronic liver disease is a leading cause of death and excessive consumption of alcohol can be a contributing factor. Little is known about the factors these individuals identify as key to achieving sustained sobriety. In this qualitative study, fourteen HIV/HCV coinfected persons who endorsed past problematic drinking were interviewed about their path to sustained sobriety. In open-ended interviews, participants often described their drinking in the context of polysubstance use and their decision to become sober as a singular response to a transcendent moment or a traumatic event. All articulated specific, concrete strategies for maintaining sobriety. The perceived effect of the HIV or HCV diagnosis on sobriety was inconsistent, and medical care as an influence on sobriety was rarely mentioned. Qualitative interviews may offer new insights on interventions and support strategies for heavy-drinking persons with HIV/HCV coinfection.

A Randomized Trial Comparing Brief Advice and Motivational Interviewing for Persons with HIV-HCV Co-infection Who Drink Alcohol.

Alcohol use contributes to the progression of liver disease in HIV-HCV co-infected persons, but alcohol interventions have never addressed low levels of alcohol use in this population. We enrolled 110 persons consuming at least 4 alcoholic drinks weekly in a clinical trial comparing two active 18-month long interventions, delivered every 3 months by phone, brief advice about drinking versus a motivational intervention. Final assessment was at 24 months. MI had larger reductions in alcohol use days than the BA arm at all follow-up assessments. The treatment by time effect was not significant for days of drinking (p = 0.470), mean drinks per day (p = 0.155), or for the continuous FIB-4 index (p = 0.175). Drinking declined in both conditions from baseline, but given the small sample, we do not have sufficient data to make any conclusion that one treatment is superior to the other.Trial Registry Trial registered at clinicaltrials.gov; Clinical Trial NCT02316184.

Reported ß-Lactam and Other Antibiotic Allergies in Solid Organ and Hematopoietic Cell Transplant Recipients.

BACKGROUND: Patients with reported ß-lactam antibiotic allergies (BLAs) are more likely to receive broad-spectrum antibiotics and experience adverse outcomes. Data describing antibiotic allergies among solid organ transplant (SOT) and hematopoietic cell transplant (HCT) recipients are limited. METHODS: We reviewed records of adult SOT or allogeneic HCT recipients from 1 January 2013 to 31 December 2017 to characterize reported antibiotic allergies at time of transplantation. Inpatient antibiotic use was examined for 100 days posttransplant. Incidence rate ratios (IRRs) comparing antibiotic use in BLA and non-BLA groups were calculated using multivariable negative binomial models for 2 metrics: days of therapy (DOT) per 1000 inpatient days and percentage of antibiotic exposure-days. RESULTS: Among 2153 SOT (65%) and HCT (35%) recipients, 634 (29%) reported any antibiotic allergy and 347 (16%) reported BLAs. Inpatient antibiotics were administered to 2020 (94%) patients during the first 100 days posttransplantation; average antibiotic exposure was 41% of inpatient-days (interquartile range, 16.7%-62.5%). BLA patients had significantly higher DOT for vancomycin (IRR, 1.4 [95% confidence interval {CI}, 1.2-1.7]; P < .001), clindamycin (IRR, 7.6 [95% CI, 2.2-32.4]; P = .001), and aztreonam in HCT (IRR, 9.7 [95% CI, 3.3-35.0]; P < .001), and fluoroquinolones in SOT (IRR, 2.9 [95% CI, 2.1-4.0]; P < .001); these findings were consistent when using percentage of antibiotic exposure-days. CONCLUSIONS: Transplant recipients are frequently exposed to antibiotics and have a high prevalence of reported antibiotic allergies. Reported BLA was associated with greater use of ß-lactam antibiotic alternatives. Pretransplant antibiotic allergy evaluation may optimize antibiotic use in this population.

Clinical Features and Outcomes of 105 Hospitalized Patients With COVID-19 in Seattle, Washington.

BACKGROUND: Washington State served as the initial epicenter of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic in the United States. An understanding of the risk factors and clinical outcomes of hospitalized patients with coronavirus disease 2019 (COVID-19) may provide guidance for management. METHODS: All laboratory-confirmed COVID-19 cases in adults admitted to an academic medical center in Seattle, Washington, between 2 March and 26 March 2020 were included. We evaluated individuals with and without severe disease, defined as admission to the intensive care unit or death. RESULTS: One hundred five COVID-19 patients were hospitalized. Thirty-five percent were admitted from a senior home or skilled nursing facility. The median age was 69 years, and half were women. Three or more comorbidities were present in 55% of patients, with hypertension (59%), obesity (47%), cardiovascular disease (38%), and diabetes (33%) being the most prevalent. Most (63%) had symptoms for ≥5 days prior to admission. Only 39% had fever in the first 24 hours, whereas 41% had hypoxia at admission. Seventy-three percent of patients had lymphopenia. Of 50 samples available for additional testing, no viral coinfections were identified. Severe disease occurred in 49%. Eighteen percent of patients were placed on mechanical ventilation, and the overall mortality rate was 33%. CONCLUSIONS: During the early days of the COVID-19 epidemic in Washington State, the disease had its greatest impact on elderly patients with medical comorbidities. We observed high rates of severe disease and mortality in our hospitalized patients.

Prevalence of Coronavirus Disease 2019 Infection and Outcomes Among Symptomatic Healthcare Workers in Seattle, Washington.

BACKGROUND: Healthcare workers (HCWs) who serve on the front lines of the coronavirus disease 2019 (COVID-19) pandemic have been at increased risk for infection due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in some settings. Healthcare-acquired infection has been reported in similar epidemics, but there are limited data on the prevalence of COVID-19 among HCWs and their associated clinical outcomes in the United States. METHODS: We established 2 high-throughput employee testing centers in Seattle, Washington, with drive-through and walk-through options for symptomatic employees in the University of Washington Medicine system and its affiliated organizations. Using data from these testing centers, we report the prevalence of SARS-CoV-2 infection among symptomatic employees and describe the clinical characteristics and outcomes among employees with COVID-19. RESULTS: Between 12 March 2020 and 23 April 2020, 3477 symptomatic employees were tested for COVID-19 at 2 employee testing centers; 185 (5.3%) employees tested positive for COVID-19. The prevalence of SARS-CoV-2 was similar when comparing frontline HCWs (5.2%) with nonfrontline staff (5.5%). Among 174 positive employees reached for follow-up at least 14 days after diagnosis, 6 reported COVID-related hospitalization; all recovered. CONCLUSIONS: During the study period, we observed that the prevalence of positive SARS-CoV-2 tests among symptomatic HCWs was comparable to that of symptomatic nonfrontline staff. Reliable and rapid access to testing for employees is essential to preserve the health, safety, and availability of the healthcare workforce during this pandemic and to facilitate the rapid return of SARS-CoV-2-negative employees to work.

Association Between Chronic Hepatitis C Virus Infection and Myocardial Infarction Among People Living With HIV in the United States.

Hepatitis C virus (HCV) infection is common among people living with human immunodeficiency virus (PLWH). Extrahepatic manifestations of HCV, including myocardial infarction (MI), are a topic of active research. MI is classified into types, predominantly atheroembolic type 1 MI (T1MI) and supply-demand mismatch type 2 MI (T2MI). We examined the association between HCV and MI among patients in the Centers for AIDS Research (CFAR) Network of Integrated Clinical Systems, a US multicenter clinical cohort of PLWH. MIs were centrally adjudicated and categorized by type using the Third Universal Definition of Myocardial Infarction. We estimated the association between chronic HCV (RNA+) and time to MI while adjusting for demographic characteristics, cardiovascular risk factors, clinical characteristics, and history of injecting drug use. Among 23,407 PLWH aged ≥18 years, there were 336 T1MIs and 330 T2MIs during a median of 4.7 years of follow-up between 1998 and 2016. HCV was associated with a 46% greater risk of T2MI (adjusted hazard ratio (aHR) = 1.46, 95% confidence interval (CI): 1.09, 1.97) but not T1MI (aHR = 0.87, 95% CI: 0.58, 1.29). In an exploratory cause-specific analysis of T2MI, HCV was associated with a 2-fold greater risk of T2MI attributed to sepsis (aHR = 2.01, 95% CI: 1.25, 3.24). Extrahepatic manifestations of HCV in this high-risk population are an important area for continued research.

Motivation to Quit Drinking in Individuals Coinfected with HIV and Hepatitis C.

Alcohol consumption is common among individuals coinfected with HIV and hepatitis C (HCV) despite the uniquely harmful effects in this population. Limited research has examined factors that could influence drinking reduction or cessation among HIV/HCV coinfected persons; this study investigates motivation to quit. Participants were 110 alcohol-consuming HIV/HCV coinfected patients recruited from medical clinics. Participants self-reported 90-day drinking frequency and intensity; alcohol-related problems; reasons to quit drinking; reasons to drink; and motivation to quit drinking. Participants consumed alcohol on 54.1 (± 26.9) of the past 90 days. In a multivariate model that controlled for demographic variables, motivation to quit drinking was directly associated with alcohol-related problems (ßy·x = 0.35, p = .007) and reasons to quit drinking (ßy·x = 0.23, p = .021), and inversely associated with drinking for enhancement (ßy·x = - 0.36, p = .004). This study identified several factors associated with motivation to quit drinking in a sample of alcohol-consuming HIV/HCV patients.

Examination of using alcohol to cope, depressive symptoms, and perceived social support in persons with HIV and Hepatitis C.

Depression is common among people living with HIV (PLWH) and some likely turn to alcohol to cope with this emotional distress. Using alcohol to cope is associated with increased alcohol use, persistent longitudinal alcohol use, and alcohol-related problems. This association is particularly concerning among PLWH who are co-infected with Hepatitis C (HCV) because alcohol adds to the damage already caused by HCV. Despite data showing the associated risks of using alcohol to cope, scant research has examined factors that might contribute to coping-based alcohol use in HIV-HCV patients, such as limited social support. Baseline data from a randomized trial of strategies to reduce alcohol use in co-infected HIV and HCV adult patients (n=110) were analyzed. Multiple linear regression models were used to estimate the association between using alcohol to cope, depression, and four aspects of social support, controlling for demographic variables. Results showed that using alcohol to cope was not significantly correlated with social support but was significantly correlated with depressive symptoms. In fact, depressive symptoms and severity of alcohol consumption accounted for nearly 45% of the variance related to coping-based alcohol use. These data highlight the central role of depression in the coping motives-alcohol use relationship among co-infected patients.

Washington state satellite HIV clinic program: a model for delivering highly effective decentralized care in under-resourced communities.

To improve access to high-quality HIV care in underserved regions of Western Washington (WA) State, we collaborated with the WA State Department of Health (DOH) and community partners to launch four satellite HIV clinics. Here, we describe this innovative clinical care model, present an estimate of costs, and evaluate patient care outcomes, including virologic suppression rates. To accomplish this, we assessed virologic suppression rates 12 months before and 12 months after the satellite clinics opened, comparing people living with HIV (PLWH) who enrolled in the satellite clinics versus all PLWH in the same regions who did not. We also determined virologic suppression rates in 2015 comparing satellite clinic versus non-satellite clinic patients and compared care quality indicators between the satellite clinics and the parent academic clinic. Results demonstrate that the change in virologic suppression rate 12 months before to 12 months after the satellite clinics opened was higher for patients who enrolled in the satellite clinics compared to all those in the same region who did not (18% versus 6%, p < 0.001). Virologic suppression in 2015 was significantly higher for satellite clinic than non-satellite clinic patients at three of four sites. Care quality indicators were met at a high level at the satellite clinics, comparable to the parent academic clinic. Overall, through community partnerships and WA DOH support, the satellite clinic program increased access to best practice HIV care and improved virologic suppression rates in difficult-to-reach areas. This model could be expanded to other regions with inadequate access to HIV practitioners, though financial support is necessary.

The Role of Current and Historical Alcohol Use in Hepatic Fibrosis Among HIV-Infected Individuals.

We examined risk factors for advanced hepatic fibrosis [fibrosis-4 (FIB)-4 >3.25] including both current alcohol use and a diagnosis of alcohol use disorder among HIV-infected patients. Of the 12,849 patients in our study, 2133 (17%) reported current hazardous drinking by AUDIT-C, 2321 (18%) had a diagnosis of alcohol use disorder, 2376 (18%) were co-infected with chronic hepatitis C virus (HCV); 596 (5%) had high FIB-4 scores >3.25 as did 364 (15%) of HIV/HCV coinfected patients. In multivariable analysis, HCV (adjusted odds ratio (aOR) 6.3, 95% confidence interval (CI) 5.2-7.5), chronic hepatitis B (aOR 2.0, 95% CI 1.5-2.8), diabetes (aOR 2.3, 95% CI 1.8-2.9), current CD4 <200 cells/mm3 (aOR 5.4, 95% CI 4.2-6.9) and HIV RNA >500 copies/mL (aOR 1.3, 95% CI 1.0-1.6) were significantly associated with advanced fibrosis. A diagnosis of an alcohol use disorder (aOR 1.9, 95% CI 1.6-2.3) rather than report of current hazardous alcohol use was associated with high FIB-4. However, among HIV/HCV coinfected patients, both current hazardous drinkers (aOR 1.6, 95% CI 1.1-2.4) and current non-drinkers (aOR 1.6, 95% CI 1.2-2.0) were more likely than non-hazardous drinkers to have high FIB-4, with the latter potentially reflecting the impact of sick abstainers. These findings highlight the importance of using a longitudinal measure of alcohol exposure when evaluating the impact of alcohol on liver disease and associated outcomes.

Not all non-drinkers with HIV are equal: demographic and clinical comparisons among current non-drinkers with and without a history of prior alcohol use disorders.

Studies of persons living with HIV (PLWH) have compared current non-drinkers to at-risk drinkers without differentiating whether current non-drinkers had a prior alcohol use disorder (AUD). The purpose of this study was to compare current non-drinkers with and without a prior AUD on demographic and clinical characteristics to understand the impact of combining them. We included data from six sites across the US from 1/2013 to 3/2015. Patients completed tablet-based clinical assessments at routine clinic appointments using the most recent assessment. Current non-drinkers were identified by AUDIT-C scores of 0. We identified a prior probable AUD by a prior AUD diagnosis in the electronic medical record (EMR) or a report of attendance at alcohol treatment in the clinical assessment. We used multivariate logistic regression to examine factors associated with prior AUD. Among 2235 PLWH who were current non-drinkers, 36% had a prior AUD with more patients with an AUD identified by the clinical assessment than the EMR. Higher proportions with a prior AUD were male, depressed, and reported current drug use compared to non-drinkers without a prior AUD. Former cocaine/crack (70% vs. 25%), methamphetamine/crystal (49% vs. 16%), and opioid/heroin use (35% vs. 7%) were more commonly reported by those with a prior AUD. In adjusted analyses, male sex, past methamphetamine/crystal use, past marijuana use, past opioid/heroin use, past and current cocaine/crack use, and cigarette use were associated with a prior AUD. In conclusion, this study found that among non-drinking PLWH in routine clinical care, 36% had a prior AUD. We found key differences between those with and without prior AUD in demographic and clinical characteristics, including drug use and depression. These results suggest that non-drinkers are heterogeneous and need further differentiation in studies and that prior alcohol misuse (including alcohol treatment) should be included in behavioural health assessments as part of clinical care.
