Effects of a hospital discharge clinic among people with HIV: Lack of early follow-up is associated with 30-day hospital readmission and decreased retention in care.

BACKGROUND: The transition between inpatient and outpatient care for hospitalized people with HIV represents an opportunity for linkage and re-engagement in care. We evaluated whether attendance at a post-hospitalization visit ('discharge clinic') within 1-2 weeks of discharge would reduce readmissions and improve retention in care (RIC) among people with HIV in San Diego, California, USA. METHODS: This was a retrospective cohort study of people with HIV hospitalized between June 2020 and November 2021. Our primary outcome was 30-day readmissions among people with HIV who did or did not attend a discharge clinic visit. Secondary outcomes included the effect of discharge clinic attendance on RIC, along with the impact of attendance at any HIV clinic visit within 30 days of discharge on readmissions and RIC. RESULTS: We evaluated 114 people with HIV, of whom 77 (67.5%) and 90 (78.9%) attended a discharge clinic visit or any HIV clinic visit within 30 days of discharge, respectively. Active substance use disorder (SUD) was associated with failing to attend a discharge clinic visit (odds ratio 0.31; 95% confidence interval 0.13-0.77). We observed no significant differences in readmissions between people with HIV who did or did not attend a discharge clinic visit; however, the former had significantly higher 6-month RIC (79.2% vs. 35.1%, p < 0.001). People with HIV attending any HIV clinic visit within 30 days of discharge had significantly fewer 30-day readmissions (8.9% vs. 29.2%, p = 0.02) and better 6-month RIC (75.6% vs. 25%, p < 0.001) than those who did not attend. CONCLUSION: Early hospital follow-up care was associated with a reduction in readmissions among people with HIV. Active SUD was a significant barrier to linkage to outpatient follow-up and RIC.

A case of disseminated coccidioidomycosis and immune reconstitution inflammatory syndrome (IRIS) in a patient with HIV/AIDS.

Coccidioidomycosis is a fungal infection endemic to the southwestern United States and Central/South America, and its range is expanding with the warming climate. People with HIV/AIDS are at increased risk of developing disseminated infection, and furthermore are at risk for developing immune reconstitution inflammatory syndrome (IRIS) if they are initiating or re-initiating anti-retroviral therapy (ART). There have been few cases of coccidioidomycosis-related IRIS reported in the literature, and there is no clear guidance on treatment. We present a case of paradoxical IRIS in a patient with AIDS who clinically improved after initiating corticosteroids.

Beyond the Syndemic of Opioid Use Disorders and HIV: The Impact of Opioids on Viral Reservoirs.

People with HIV are more likely to have opioid use disorder and to be prescribed opioids for chronic pain than the general population; however, the effects of opioids on the immune system and HIV persistence have not been fully elucidated. Opioids may affect HIV reservoirs during their establishment, maintenance, and reactivation by enhancing HIV infectivity and replication due to upregulation of co-receptors and impairment of innate antiviral responses. Opioids may also modulate immune cell functioning and microbial translocation and can reverse viral latency. In this review, we summarize the current findings for and against the modulating effects of opioids on HIV cellular and anatomical reservoirs, highlighting the current limitations that affect in vitro, ex vivo, and in vivo studies in the field. We propose further research targets and potential strategies to approach this topic.

A Novel UHPLC-MS/MS Method for the Quantification of Seven Opioids in Different Human Tissues.

BACKGROUND: Opioids are considered the cornerstone of pain management: they show good efficacy as a first-line therapy for moderate to severe cancer pain. Since pharmacokinetic/pharmacodynamic information about the tissue-specific effect and toxicity of opioids is still scarce, their quantification in post-mortem autoptic specimens could give interesting insights. METHODS: We describe an ultra-high-performance liquid chromatography coupled with tandem mass spectrometry method for the simultaneous quantification of methadone, morphine, oxycodone, hydrocodone, oxymorphone, hydromorphone and fentanyl in several tissues: liver, brain, kidney, abdominal adipose tissue, lung and blood plasma. The presented method has been applied on 28 autoptic samples from different organs obtained from four deceased PLWH who used opioids for palliative care during terminal disease. RESULTS: Sample preparation was based on tissue weighing, disruption, sonication with drug extraction medium and a protein precipitation protocol. The extracts were then dried, reconstituted and injected onto the LX50 QSight 220 (Perkin Elmer, Milan, Italy) system. Separation was obtained by a 7 min gradient run at 40 °C with a Kinetex Biphenyl 2.6 µm, 2.1 × 100 mm. Concerning the analyzed samples, higher opioids concentrations were observed in tissues than in plasma. Particularly, O-MOR and O-COD showed higher concentrations in kidney and liver than other tissues (>15-20 times greater) and blood plasma (>100 times greater). CONCLUSIONS: Results in terms of linearity, accuracy, precision, recovery and matrix effect fitted the recommendations of FDA and EMA guidelines, and the sensitivity was high enough to allow successful application on human autoptic specimens from an ethically approved clinical study, confirming its eligibility for post-mortem pharmacological/toxicological studies.

Shared Decision-Making Concerning Anal Cancer Screening in Persons With Human Immunodeficiency Virus.

BACKGROUND: Anal high-grade squamous intraepithelial lesion (aHSIL) is the immediate precursor of anal cancer. Anal cytology is a recommended screening test to identify aHSIL among people with human immunodeficiency virus (HIV; PWH). Heterogeneity of risk for invasive anal cancer among PWH suggests the value of a shared decision-making framework regarding screening. METHODS: Using a longitudinal HIV cohort with a comprehensive anal cancer screening program, we estimated the adjusted probabilities of having aHSIL on the first anal cytology. We used logistic regression models with inverse probability weighting to account for differential screening in the cohort and to construct a predicted probability nomogram for aHSIL. Sensitivity analysis was performed to estimate aHSIL prevalence corrected for misclassification bias. RESULTS: Of 8139 PWH under care between 2007 and 2020, 4105 (49.8%) underwent at least 1 anal cytology test. First-time cytology aHSIL was present in 502 (12.2%) PWH. The adjusted probability of having aHSIL varied from 5% to 18% depending on patient characteristics. Prespecified factors in the aHSIL prediction model included nadir CD4 cell count, ethnicity, race, age, sex, gender identity, and HIV risk factors. The ability of the model to discriminate cytological aHSIL was modest, with an area under the curve of 0.63 (95% confidence interval, .60-.65). CONCLUSIONS: PWH are at increased risk for aHSIL and invasive anal cancer. Risk, however, varies by patient characteristics. Individual risk factor profiles predictive of aHSIL can be modeled and operationalized as nomograms to facilitate shared decision-making conversations concerning anal cancer screening.

Coccidioidomycosis Seroincidence and Risk among Military Personnel, Naval Air Station Lemoore, San Joaquin Valley, California, USA1.

We conducted a retrospective cohort study that tested 2,000 US military personnel for Coccidioides antibodies in a disease-endemic region. The overall incidence of seroconversion was 0.5 cases/100 person-years; 12.5% of persons who seroconverted had illnesses requiring medical care. No significant association was found between demographic characteristics and seroconversion or disease.

Statin usage and cardiovascular risk among people living with HIV in the U.S. Military HIV Natural History Study.

OBJECTIVES: Using the American College of Cardiology/American Heart Association 2013 atherosclerotic cardiovascular disease (ASCVD) management guidelines, we conducted a retrospective cross-sectional analysis of people living with HIV in the US Military HIV Natural History Study to determine whether individuals were receiving statins when indicated. METHODS: Prescription data was taken from Military Health System data. Statin eligibility was defined by ASCVD guidelines. We used the 10-year ASCVD pooled cohorts' equation to evaluate risk for each participant. RESULTS: Across all categories, 31.9% (n = 390) of individuals met criteria for statin use, and when adding these subjects to the number of those already receiving statins (n = 96), 62.1% of all eligible subjects (n = 302/486) were actually receiving statin therapy. In multivariable analysis, individuals of African American race [odds ratio (OR) = 0.48, 95% confidence interval (CI): 0.31-0.73] or Hispanic ethnicity (OR = 0.42, 95% CI: 0.19-0.94) were less likely to receive statin prescriptions than white individuals. Individuals with a higher CD4 count (OR = 1.12, 95% CI: 1.05-1.20 per 100 cells/µL]) were significantly more likely to receive a statin prescription. CONCLUSIONS: These data highlight discrepancies between ASCVD guidelines and primary care management of people living with HIV (PLWH) in the military health system, along with important racial differences. Targeted interventions are critical to identify and treat appropriate candidates for statin therapy among PLWH in the military and other settings.

High burden of cryptococcal antigenemia and meningitis among patients presenting at an emergency department in Maputo, Mozambique.

BACKGROUND: Cryptococcal meningitis is a leading cause of HIV-related mortality in sub-Saharan Africa, however, screening for cryptococcal antigenemia has not been universally implemented. As a result, data concerning cryptococcal meningitis and antigenemia are sparse, and in Mozambique, the prevalence of both are unknown. METHODS: We performed a retrospective analysis of routinely collected data from a point-of-care cryptococcal antigen screening program at a public hospital in Maputo, Mozambique. HIV-positive patients admitted to the emergency department underwent CD4 count testing; those with pre-defined abnormal vital signs or CD4 count ≤ 200 cells/µL received cryptococcal antigen testing and lumbar punctures if indicated. Patients with CM were admitted to the hospital and treated with liposomal amphotericin B and flucytosine; their 12-week outcomes were ascertained through review of medical records or telephone contact by program staff made in the routine course of service delivery. RESULTS: Among 1,795 patients screened for cryptococcal antigenemia between March 2018-March 2019, 134 (7.5%) were positive. Of patients with cryptococcal antigenemia, 96 (71.6%) were diagnosed with CM, representing 5.4% of all screened patients. Treatment outcomes were available for 87 CM patients: 24 patients (27.6%) died during induction treatment and 63 (72.4%) survived until discharge; of these, 38 (60.3%) remained in care, 9 (14.3%) died, and 16 (25.3%) were lost-to follow-up at 12 weeks. CONCLUSIONS: We found a high prevalence of cryptococcal antigenemia and meningitis among patients screened at an emergency department in Maputo, Mozambique. High mortality during and after induction therapy demonstrate missed opportunities for earlier detection of cryptococcal antigenemia, even as point-of-care screening and rapid assessment in an emergency room offer potential to improve outcomes.

Sexual Risk Behaviors Associated with Sexually Transmitted Infections in a US Military Population Living with HIV After the Repeal of "Don't Ask, Don't Tell".

Risk behaviors associated with sexually transmitted infections (STIs) among people living with HIV (PLWH) have not been well characterized in the US military. We identified risk behaviors associated with a new STI in this population after the repeal of "Don't Ask, Don't Tell." US Military HIV Natural History Study participants who completed the risk behavior questionnaire (RBQ) between 2014 and 2017 and had at least 1 year of follow-up were included (n = 1589). Logistic regression identified behaviors associated with incident STI in the year following RBQ completion. Overall, 18.9% acquired an STI and 52.7% reported condom use at last sexual encounter. Compared with those with no new sex partners, participants with between one and four or five or more new partners were 1.71 [1.25-2.35] and 6.12 [3.47-10.79] times more likely to get an STI, respectively. Individuals reporting low or medium/high perceived risk of STI were 1.83 [1.23-2.72] and 2.65 [1.70-4.15] times more likely to acquire a new STI than those reporting no perceived risk, respectively. Participants who preferred not to answer about sexual preference, number of new partners, or perceived STI risk were also more likely to acquire a new STI. Our study illustrates that despite regular access to health care and accurate perceptions of risk, rates of STI among PLWH remain high in the US military setting, as in others. Given the potential individual and public health consequences of STI coinfection after HIV, more work is needed to assess interventions aimed at sexual behavior change for PLWH.

Comparable Disease Severity by Influenza Virus Subtype in the Acute Respiratory Infection Consortium Natural History Study.

INTRODUCTION: Since the influenza A/H1N1 pandemic of 2009 to 2010, numerous studies have described the clinical course and outcome of the different subtypes of influenza (A/H1N1, A/H3N2, and B). A recent systematic literature review concluded that there were no appreciable differences in either clinical presentation or disease severity among these subtypes, but study parameters limit the applicability of these results to military populations. We sought to evaluate differences in disease severity among influenza subtypes in a cohort of healthy, primarily outpatient adult U.S. Department of Defense beneficiaries. MATERIALS AND METHODS: From 2009 to 2014, we enrolled otherwise healthy adults age 18 to 65 years with influenza-like illness in an observational cohort study based in 5 U.S. military medical centers. Serial nasopharyngeal swabs were collected for determination of etiology and viral shedding by polymerase chain reaction. The presence and severity of symptoms was assessed by interview and patient diary. RESULTS: Over a 5-year period, a total of 157 adults with laboratory-confirmed influenza and influenza subtype were enrolled. Of these, 69 (44%) were positive for influenza A(H1N1), 69 (44%) for influenza A(H3N2), and 19 (12%) for influenza B. About 61% were male, 64% were active duty military personnel, and 72% had received influenza vaccine in the past 8 months. Almost 10% were hospitalized with influenza. Seasonal influenza virus distribution among enrollees mirrored that of nationwide trends each year of study. Individuals with A/H1N1 had upper respiratory composite scores that were lower than those with A/H3N2. Multivariate models indicated that individuals with A(H1N1) and B had increased lower respiratory symptom scores when compared to influenza A(H3N2) (A[H1N1]: 1.51 [95% CI 0.47, 2.55]; B: 1.46 [95% CI 0.09, 2.83]), whereas no other differences in symptom severity scores among influenza A(H1N1), influenza A(H3N2), and influenza B infection were observed. Overall, influenza season (maximum in 2012-2013 season) and female sex of the participant were found to be associated with increased influenza symptom severity. CONCLUSIONS: Our study of influenza in a cohort of otherwise healthy, outpatient adult Department of Defense beneficiaries over 5 influenza seasons revealed few differences between influenza A(H1N1), influenza A(H3N2), and influenza B infection with respect to self-reported disease severity or clinical outcomes. This study highlights the importance of routine, active, and laboratory-based surveillance to monitor ongoing trends and severity of influenza in various populations to inform prevention measures.

The US Military HIV Natural History Study: Informing Military HIV Care and Policy for Over 30 Years.

INTRODUCTION: In October 1985, 4 years after the initial descriptions of the acquired immunodeficiency syndrome (AIDS), the U.S. Department of Defense (DoD) began routine screening for human immunodeficiency virus (HIV) infection to prevent infected recruits from exposure to live virus vaccines, implemented routine active-duty force screening to ensure timely care and help protect the walking blood bank, and initiated the U.S. Military HIV Natural History Study (NHS) to develop epidemiologic, clinical, and basic science evidence to inform military HIV policy and establish a repository of data and specimens for future research. Here, we have reviewed accomplishments of the NHS over the past 30 years and sought to describe relevant trends among NHS subjects over this time, with emphasis on combination antiretroviral therapy (cART) use and non-AIDS comorbidities. METHODS: Subjects who were prospectively enrolled in the NHS from 1986 through 2015 were included in this analysis. Time periods were classified by decade of study conduct, 1986-1995, 1996-2005, and 2006-2015, which also correlate approximately with pre-, early-, and late-combination ART (cART) eras. Analyses included descriptive statistics and comparisons among decades. We also evaluated mean community log10 HIV viral load (CVL) and CD4 counts for each year. RESULTS: A total of 5,758 subjects were enrolled between 1986 and 2015, of whom 92% were male with a median age of 28 years, and 45% were African-American, 42% Caucasian, and 13% Hispanic/other. The proportion of African-Americans remained stable over the decades (45%, 47%, and 42%, respectively), while the proportion of Hispanic/other increased (10%, 13%, and 24%, respectively). The CD4 count at HIV diagnosis has remained high (median 496 cells/uL), while the occurrence of AIDS-defining conditions (excluding low CD4 count) has decreased by decade (36.7%, 5.4%, and 2.9%, respectively). Following the introduction of effective cART in 1996, CVL declined through 2000 as use increased and then plateaued until guidelines changed. After 2004, cART use again increased and CVL declined further until 2012-15 when the vast majority of subjects achieved viral suppression. Non-AIDS comorbidities have remained common, with approximately half of subjects experiencing one or more new diagnoses overall and nearly half of subjects diagnosed between 2006 and 2015, in spite of their relatively young age, shorter median follow-up, and wide use of cART. CONCLUSIONS: The US Military HIV NHS has been critical to understanding the impact of HIV infection among active-duty service members and military beneficiaries, as well as producing insights that are broadly relevant. In addition, the rich repository of NHS data and specimens serves as a resource to investigators in the DoD, NIH, and academic community, markedly increasing scientific yield and identifying novel associations. Looking forward, the NHS remains relevant to understanding host factor correlates of virologic and immunologic control, biologic pathways of HIV pathogenesis, causes and consequences of residual inflammation in spite of effective cART, identifying predictors of and potential approaches to mitigation of excess non-AIDS comorbidities, and helping to understand the latent reservoir.

A Comparison of Pretravel Health Care, Travel-Related Exposures, and Illnesses among Pediatric and Adult U.S. Military Beneficiaries.

We evaluated differences in pretravel care, exposures, and illnesses among pediatric and adult travelers, using a prospective, observational cohort. Eighty-one pediatric travelers were matched 1:1 with adult military dependents by travel region, destination's malaria risk, and travel duration. Pediatric travelers were more likely to have coverage for hepatitis A and B (90% versus 67% of adults; 85% versus 44%), visit friends and relatives (36% versus 16%), report mosquito bites (69% versus 44%), and have close contact with wild or domesticated animals (40% versus 20%) than adults (P < 0.05). Subjects < 10 years of age were less likely to be prescribed antibiotics (28% versus 95%; RR = 0.63; 95% CI: 0.46-0.85) and antidiarrheals (9% versus 100%; RR = 0.10; 95% CI: 0.03-0.29) for travelers' diarrhea (TD) self-treatment than adults. Travel medicine providers should emphasize strategies for vector avoidance, prevention of animal bites and scratches, and TD self-treatment in pediatric pretravel consultations.

Relationship between depression and risk behaviors in a US Military population with HIV infection.

This study evaluated the relationships between depression trajectories, depression diagnosis and sexual risk behaviors in the US Military HIV Natural History Study. Risk behavior survey data, a coded diagnosis of depression, available Center for Epidemiological Studies Depression measures, and self-reported depressive symptoms (n = 662) were utilized. Latent class analysis created 3 classes of depression trajectories, namely, low depression (LD, n = 378), recent-onset depression (ROD, n = 170), and high depression (HD, n = 114) trajectories. Overall, participants with clinically diagnosed depression were less likely to report often using condoms with new sexual partners in the past 3 months than those who have never been diagnosed with depression (OR 0.15, 95% CI 0.49-2.53). Participants with ROD (OR 0.52, 95% CI 0.28-0.97) and HD (OR 0.48, 95% CI 0.24-0.96) trajectories were less likely to report often using condoms with new sexual partners in the past 3 months than those with LD trajectories. Moreover, those with either ROD (OR 2.13, 95% CI 1.19-3.80) or HD (OR 2.74, 95% CI 1.43-5.24) trajectories were more likely to have had sex with ≥2 new sexual partners in the last 3 months than those with LD trajectories. Continued efforts targeting HIV-infected persons with mental health disorders are warranted to reduce sexual risk behaviors.

Posttraumatic Stress Disorder and Neurocognitive Impairment in a U.S. Military Cohort of Persons Living with HIV.

Objective: Neurocognitive impairment (NCI) is a well-known complication of human immunodeficiency virus (HIV) infection and may be influenced by a number of psychological factors. We examined the relationship between NCI and mental health disorders, including posttraumatic stress disorder (PTSD), in a cohort of 189 active-duty and retired U.S. military men living with HIV. Methods: Participants completed selected modules of the Composite International Diagnostic Interview (CIDI) to ascertain the presence of PTSD, major depressive disorder, and other mental health diagnoses. We also obtained demographic data, including history of head trauma, via personal interview. NCI was assessed with a comprehensive battery of standardized neuropsychological tests. Results: The median age of study subjects was 36 years (interquartile range [IQR] 28 to 43) and median total years of education was 14 (IQR 12 to 16). NCI was diagnosed in 19% of subjects. Individuals with and without a history of PTSD were similar with respect to most HIV-related characteristics; however, the former were significantly more likely to have a prior acquired immunodeficiency syndrome (AIDS) diagnosis. In multivariate analysis, lifetime history of PTSD was independently associated with NCI (odds ration [OR] = 6.12; 95% confidence interval [CI] = 1.85, 20.27), while a history of head of trauma was negatively associated (OR = 0.37 95% CI = 0.15,0.92). Conclusions: Our findings demonstrate that PTSD is an important predictor of NCI in this U.S. military cohort. HIV-infected individuals with cognitive difficulties should be screened for mental health disorders, including PTSD, and prospective studies of the longitudinal relationship between PTSD and NCI, as well as the impact of PTSD treatment on future NCI, are warranted.

Persistent Low-level Viremia While on Antiretroviral Therapy Is an Independent Risk Factor for Virologic Failure.

BACKGROUND: Whether persistent low-level viremia (pLLV) predicts virologic failure (VF) is unclear. We used data from the US Military HIV Natural History Study (NHS), to examine the association of pLLV and VF. METHODS: NHS subjects who initiated combination antiretroviral therapy (ART) after 1996 were included if they had 2 or more VLs measured with a lower limit of detection of ≤50 copies/mL. VF was defined as a confirmed VL ≥200 copies/mL or any VL >1000 copies/mL. Participants were categorized into mutually exclusive virologic categories: intermittent LLV (iLLV) (VL of 50-199 copies/mL on <25% of measurements), pLLV (VL of 50-199 copies/mL on ≥25% of measurements), high-level viremia (hLV) (VL of 200-1000 copies/mL), and continuous suppression (all VL <50 copies/mL). Cox proportional hazards models were used to evaluate the association between VF and LLV; hazard ratios and 95% confidence interval (CI) are presented. RESULTS: Two thousand six subjects (median age 29.2 years, 93% male, 41% black) were included; 383 subjects (19%) experienced VF. After adjusting for demographics, VL, CD4 counts, ART regimen, prior use of mono or dual antiretrovirals, and time to ART start, pLLV (3.46 [2.42-4.93]), and hLV (2.29 [1.78-2.96]) were associated with VF. Other factors associated with VF include black ethnicity (1.33 [1.06-1.68]) and antiretroviral use prior to ART (1.79 [1.34-2.38]). Older age at ART initiation (0.71 [0.61-0.82]) and non-nucleoside reverse transcriptase inhibitor (0.68 [0.51-0.90]) or integrase strand transfer inhibitor use (0.26 [0.13-0.53]) were protective. CONCLUSION: Our data add to the body of evidence that suggests persistent LLV is associated with deleterious virologic consequences.

Extragenital chlamydia infection among active-duty women in the United States Navy.

BACKGROUND: Pharyngeal and anorectal reservoirs of gonorrhea (GC) and chlamydia (CT) are increasingly recognized among heterosexual women. While a number of studies performed at sexually transmitted disease (STD) clinics have found a high prevalence of extragenital GC/CT infection, such screening is typically not offered during routine primary care visits for women. We sought to define the prevalence of and factors associated with extragenital GC/CT among women in the U.S. Navy. METHODS: We recruited servicewomen stationed in San Diego, California, between the ages of 18 and 25 who presented for an annual physical exam between January and September, 2017. Nucleic acid amplification testing was performed on swabs collected at endocervical, oropharyngeal and anorectal sites to assess the presence of GC/CT. An anonymous behavioral questionnaire was also administered to characterize sexual risk. Descriptive statistics were used to compare women with and without a prior history of any sexually transmitted infection (STI) (self-report) along with a current GC/CT diagnosis. This study was approved by the Institutional Review Board of the Uniformed Services University of Health Sciences. RESULTS: Of the 75 patients who were approached, 60 subjects were enrolled in the study, including white 20 (33.3%), black/African American 18 (31.0%), Hispanic/Latina 13 (21.7%) and Asian/Pacific Islander 9 (15.5%) women. Among all the women, six (10.0%) were diagnosed with CT infection, all via endocervical exam. Of these, five (8.3%) had concurrent anorectal infection, including two cases (3.3%) accompanied by pharyngeal infection. Of the subjects, 15 (25.0%) reported anal intercourse in their most recent sexual encounter, most of which was condomless (13/15, 86.7%). A high number of women who reported sex with a casual male partner (19/45, 42.2%) reported rarely or never using condoms; last, 41.7% consuming at least 3 drinks on a typical drinking day, and one-third of the reported drinking more than once per week. CONCLUSIONS: We found a high prevalence of anorectal CT infection, although no infections were detected without concurrent endocervical involvement. Nonetheless, the high prevalence of condomless anal intercourse reported by participants argues for further study and ongoing consideration of extragenital screening among high-risk patients. Behavioral interventions are also warranted given the high prevalence of sexual and related risk factors.

Age, Race, and At-Risk Drinking in an HIV-infected U.S. Military Cohort.

INTRODUCTION: There is a high prevalence of at-risk drinking in the U.S. military. Among HIV-infected individuals, alcohol abuse confers additional risk for adverse health outcomes. In the military, however, the characteristics of HIV-infected individuals who engage in high-risk drinking are not well defined. The purpose of this study was to assess risk factors associated with at-risk drinking in an HIV-positive longitudinal cohort of DoD beneficiaries. MATERIALS AND METHODS: Annual prevalence of at-risk drinking was calculated for members of the U.S. Military HIV Natural History Study who initiated highly active antiretroviral therapy (HAART) during or after January 2006 through May 2014; each participant completed at least one self-reported alcohol survey within a year of HAART initiation. Univariate and multivariable logistic regression was used to analyze factors associated with at-risk drinking. RESULTS: Sixty-six percent of subjects (495/752) reported at-risk drinking on at least one survey after HAART initiation. At-risk drinkers were more likely to be Active Duty compared to Retired (OR 0.65 95% CI [0.46, 0.92]). In multivariate models, Caucasian race (OR 3.30 95% CI [2.31, 4.71]); Hispanic/other race (OR 2.17 95% CI [1.51, 3.14]) and younger age (OR 0.61 per 10 years older, [95%CI 0.49, 0.75]) were significantly associated with at-risk drinking. Single relationship status (OR 1.51 95% CI [1.08, 2.13]) was also associated with at-risk drinking. CONCLUSIONS: Consistent with general alcohol consumption patterns in the military, we found a high prevalence of at-risk drinking among individuals with HIV infection, which was associated most closely with young, non-African Americans. Targeting interventions toward this group will be important to reduce at-risk drinking and its potential for HIV-related complications.

Herpes Zoster Rates Continue to Decline in People Living With Human Immunodeficiency Virus but Remain Higher Than Rates Reported in the General US Population.

In the antiretroviral therapy era, herpes zoster incidence continued to decline in people living with HIV (PLWH). However, at 0.9 cases/100 person-years, rates in PLWH are substantially higher than the general US population; emphasizing the needs for studies of the subunit vaccine in PLWH.

Association between quantitative varicella-zoster virus antibody levels and zoster reactivation in HIV-infected persons.

BACKGROUND: Varicella-zoster virus (VZV) reactivation is common but difficult to predict in HIV-infected persons. OBJECTIVE: Since qualitative VZV antibodies can determine past VZV disease or vaccination, we evaluated whether quantitative VZV antibody levels over time can predict future zoster. STUDY DESIGN: US Military HIV Natural History (NHS) participants with a zoster diagnosis at least 5 years after HIV diagnosis (n = 100) were included. Zoster-negative controls (n = 200) were matched by age, race, gender, and CD4 count at HIV diagnosis. Repository plasma specimens collected at baseline and prior to zoster diagnosis were evaluated using a quantitative anti-VZV ELISA assay. Differences in quantitative VZV levels were analyzed by Wilcoxon Mann-Whitney and Fisher's exact tests. RESULTS: Median CD4 count at HIV diagnosis was similar for cases and controls (535 [IQR 384-666] vs. 523 [IQR 377-690] cells/µL; p = 0.940), but lower for cases at zoster diagnosis (436 [IQR 277-631] vs. 527 [IQR 367-744] cells/µL; p = 0.007). Antiretroviral therapy (ART) use prior to zoster diagnosis was lower for cases (52.0%) compared to controls (64.5%; p = 0.025). Cases had similar mean VZV antibody levels prior to zoster diagnosis compared to controls [2.25 ± 0.85 vs. 2.44 ± 0.96 index value/optical density (OD) ratio; p = 0.151] with no difference in the change in antibody levels over time (0.08 ± 0.71 vs. 0.01 ± 0.94 index value/OD per year; p = 0.276). CONCLUSION: Quantitative VZV antibody levels are stable in HIV-infected persons and do not predict zoster reactivation. Low CD4 count and lack of ART use appear to be better predictors of future zoster diagnosis.
