TNF-α and IL-6 serum levels: Neurobiological markers of alcohol consumption in alcohol-dependent patients?

We investigated the serum levels of IL-6 and TNF-α in 30 male alcohol-dependent patients during withdrawal (day 1, 7, and 14) and compared them with the levels obtained from 18 healthy male controls. IL-6 (day 1: T = 2,593, p = 0.013; day 7: T = 2,315, p = 0.037; day 14: T = 1,650, p = 0.112) serum levels were significantly increased at the beginning of alcohol withdrawal. TNF-α (T = 3,202, p = 0.03) serum levels were significantly elevated in the patients' group during the whole period of withdrawal. IL-6 serum levels decreased significantly during withdrawal (F = 16.507, p < 0.001), whereas TNF-α levels did not change significantly (day 1–14). IL-6 serum levels were directly associated with alcohol consumption (r = 0.392, p = 0.047) on day 1. Moreover, the IL-6 serum levels were associated with alcohol craving (PACS total score day 1: r = −0.417, p = 0.022, the score of the obsessive subscale of the OCDS on day 14 [r = −0.549, p = 0.022]), depression (r = −0.507, p = 0.005), and trait anxiety (r = −0.674, p < 0.001) on day 1. We found an association with the duration of active drinking following the last period of abstinence and the TNF-α serum levels (day 1:r = 0.354, p = 0.009; day 7: r = 0.323, p = 0.022; day 14: r = 0.303, p = 0.034) as well as an association with the severity of alcohol dependence measured by the SESA scale (r = 0.454, p = 0.015). Moreover, we found a significant association between the BDNF serum levels and the TNF-α serum levels (r = −0.426, p = 0.021). Our results support an association between alterations in TNF-α and IL-6 serum levels and alcohol consumption.     

“When You Get Old Like This … You Don't Run Those Risks Anymore”: Influence of Age on Sexual Risk Behaviors and Condom Use Attitudes Among Methamphetamine-Using Heterosexual Women with a History of Partner Violence

BackgroundDrug use and partner violence affect older women, yet few studies highlight age-specific HIV risks and prevention strategies. This study compares sexual risk behaviors, condom use attitudes, and HIV knowledge between midlife/older women (ages 45+) and younger women (ages 18–44) reporting methamphetamine use and partner violence in San Diego, California.MethodsOur mixed methods study used themes from a qualitative substudy (n = 18) to inform logistic regression analysis of baseline data from an HIV behavioral intervention trial (n = 154).FindingsAge-related qualitative themes included physiologic determinants, HIV knowledge, and “dodging the bullet,” referring to a lifetime of uncertainty surrounding HIV serostatus after engaging in unsafe drug and sex practices. Midlife/older age was associated with never being married (24.2% vs. 51.2; p = .03), having less than a high school education/GED (12.1% vs. 34.7%; p = .04), lower condom use self-efficacy (2.87 vs. 3.19; p = .03), lower positive outcome expectancies (1.9 vs. 2.1; p = .04), and lower HIV knowledge (85.3% vs. 89.7%; p = .04); however, sexual risk behaviors were not associated with age group. In the multivariate analysis, midlife/older age remained independently associated with lower condom use self-efficacy (adjusted odds ratio, 0.49; 95% CI, 0.27–0.87) and lower HIV knowledge (adjusted odds ratio, 0.96; 95% CI, 0.93–0.99).ConclusionsMidlife/older methamphetamine-using women with experiences of partner violence present similar sexual risk profiles, but possess different HIV-related knowledge and attitudes toward prevention methods compared with their younger counterparts. Clinicians and public health practitioners can have a positive impact on this overlooked population by assessing HIV risks during routine screenings, encouraging HIV testing, and providing age-appropriate HIV prevention education.     

The presence of hepatitis B core antibody is associated with more advanced liver disease in alcoholic patients with cirrhosis

Background

Liver disease is more severe in patients with chronic hepatitis B virus (HBV) infections and alcohol-induced liver injury. Whether the same is true for alcoholic patients with cirrhosis who have recovered from previous HBV infections remains to be determined.

Objectives

To document the extent of liver disease in alcoholic patients with cirrhosis who test negative for hepatitis B surface antigen (HBsAg) and test positive for antibody to hepatitis B core antigen (anti-HBc).

Methods

Two hundred fifty-four alcoholic patients with cirrhosis were divided into anti-HBc-positive (N = 171) and anti-HBc-negative (N = 83) cohorts. Demographic, clinical, and biochemical features were retrospectively analyzed. Prognostic scores and the prevalence of patients at high risk for short-term mortality were calculated. Logistic regression was used to identify factors associated with an increased risk for short-term mortality.

Results

Jaundice was more common in the anti-HBc-positive cohort (32.2% vs. 18.1%, p = 0.02). This cohort also had higher serum bilirubin (70.9 vs. 50.4 μm/L, p = 0.03), prothrombin times (15.6 vs. 14.4 s, p = 0.01), MELD scores (8.5 vs. 4.6, p = 0.01), i-MELD scores (28.6 vs. 24.7, p = 0.03), MDF scores (14.2 vs. 6.8, p = 0.02) and ABIC scores (7.2 vs. 6.6, p = 0.01). In addition, anti-HBC-positive patients were more often at high risk for short-term mortality (40.4% vs. 26.5%, p = 0.03). Multivariate analysis identified anti-HBc-positive status (OR: 1.84; 95% CI: 1.10–3.36) and alcohol intake ≥150 g/day (OR: 2.01; 95% CI: 1.10–3.66) as independent risk factors for high risk of mortality.

Conclusion

The anti-HBc-positive state is associated with more advanced liver disease in alcoholic patients with cirrhosis. A prospective study including HBV–DNA testing and liver biopsies should be considered to validate and further elucidate these findings.     

Épidémie du VIH chez les travailleuses du sexe en Guinée : prévalence,facteurs associés,vulnérabilité et tendances 2001–2007

BackgroundEstimate the associations between potential risk factors and HIV prevalence, as well as the trends from 2001 through 2007 of these indicators. Describe the vulnerability of female sex workers to in Guinea.MethodsFemale sex workers in Guinea were interviewed in 2001 (n = 339) and 2007 (n = 598) and then screened for HIV. This was a nationwide survey using a unique protocol. Associations between potential risk factors and HIV prevalence were tested, and their trends from 2001 through 2007 estimated, after adjustment using Generalized Estimating Equations.ResultsIn 2001, HIV was associated with illiteracy (PR = 1.41; p = 0.2), and with genital ulcer symptom (PR = 1.89; p = 0.001). In 2007, it was associated with illiteracy (RP = 1, p = 0.03), and with older age (PR for 10 years = 1.29; p = 0.004). The profile of illiterate female sex workers included low price per sexual encounter in both 2001 and 2007, greater number of clients, and lesser exposure to HIV/Aids counselling in 2001. From 2001 to2007, increases were noted for the number of clients by female sex workers (p < 0.0001), price per sexual encounter (p < 0.0001), condom use (p < 0.0001) and exposure to HIV/Aids counselling (p < 0.0001); decreases were noted for symptoms of sexually transmitted diseases (p < 0.0001) and HIV prevalence among female sex workers aged less than 20 years (p = 0.005).ConclusionFrom 2001 through 2007, condom use and exposure to HIV/Aids counselling increased in Guinea while symptoms of sexually transmitted diseases and HIV prevalence declined. Nevertheless, illiterate female sex workers remained highly vulnerable.     

Changes in cytokine levels during admission and mortality in acute alcoholic hepatitis

Cytokine levels are raised in acute alcoholic hepatitis. However, there are disparate results regarding the duration of altered plasma levels, and there are also discrepancies about the relation of changes during the first 15 days after admission with short-term (in-hospital) or long-term mortality. In 56 patients with acute alcoholic hepatitis we found that IL-8, IL-4, Interferon-γ (IFN-γ), malondialdehyde and C-reactive protein remained higher in patients than in 18 age- and sex-matched controls at admission, at the 7th day and at the 15th day after admission. Moreover, IL-4 levels (and to a lesser extent, IL-10 and IFN-γ ones) increased along the three determinations. However, comparing patients who died during the admission with those who did not, there were no statistically significant differences, but there was a nearly significant trend for MDA (Z = 1.89; p = 0.059), with higher levels among those who died. When changes between the first and the second determinations were compared with long-term survival, only IL-8 and IFN-γ showed a relation with mortality. IFN-γ values increased among those who survived and decreased among those who died (p = 0.048). IFN-γ values at the first determination also showed a relation with long-term mortality, especially when patients with IFN-γ values in the first quartile were compared with those of the 4th one (log rank = 5.64; p = 0.018; Breslow = 4.64; p = 0.031). Besides Interferon-γ, only C-reactive protein showed differences between the first and the 4th quartile regarding mortality (Log rank = 4.50; p = 0.034; Breslow 4.33; p = 0.038). In contrast with other studies, no relation was found between TNF-α or IL-6 and mortality.     

Immediate physical needs of refugees during the Ukrainian armed conflict of 2022

PurposeThe study assessed the physical needs of Ukrainian refugees and internally displaced persons during the ongoing Ukrainian armed conflict of 2022. We aimed to investigate the immediate physical needs of the refugees that may affect their somatic condition during the armed conflict when they did not yet reach their final destination or just reached a safety zone.MethodsThe questionnaire-based prospective repeated cross-sectional study (three study groups) and the longitudinal study (one group) were undertaken in Ukraine and Israel among 19,101 refugees and 828 controls from February 24 to April 9. We assessed the availability of basic somatic necessities (water, food, clothing, hygiene, and sleep) and the general physical fatigue of internal, moving abroad, and arriving to safety refugees with scores ranging from 35 (normal) to 7 (extremely inadequate).ResultsThe average score of 26.8 ± 1.8 indicates that the participants experienced somatic problems even being healthy. In Ukraine, the score for moving abroad refugees (n = 16,449) dropped from 26.8 ± 0.6 to 23.5 ± 0.6 (p = 0.03) during the study period. Internally displaced persons (n = 1200) remained physically stable with a score of 27.5 ± 0.7. In Israel, group-organized refugees (n = 796) were relatively normal somatically (30.0 ± 0.6) while independent refugees (n = 656) were exhausted having a score of 24.2 ± 0.7 (p = 0.03 vs. group-organized).ConclusionDuring hostilities, refugees, internally displaced persons, and regular inhabitants are somatically affected but to varying degrees. For refugees, group-organized travel abroad is the best option to maintain adequate physical condition, followed by an internal refugee status, and travel abroad independently (the worst strategy).     

Acute ethanol administration inhibits Toll-like receptor 4 signaling pathway in rat intestinal epithelia

Excess alcohol intake, as in binge drinking, increases susceptibility to microbial pathogens. Alcohol impairs macrophage function by suppression of the Toll-like receptor 4 (TLR4) pathway. This study investigated the effects of acute ethanol intake on the TLR4 pathway in rat intestinal epithelia, which usually encounters luminal antigens at first and participates in the development of intestinal immunity. Twenty Wistar rats were randomly assigned to an ethanol group given ethanol as a 25% (v/v) solution in water at 7.5 g/kg, or a control group given saline, by oral gavage daily for 3 days. The epithelial histology and ultrastructure, the intestinal microflora, peripheral and portal venous plasma lipopolysaccharide (LPS) levels, and somatostatin (SST) levels in the peripheral plasma and small intestine were evaluated. Somatostatin receptor 2 (SSTR2), TLR4, TANK binding kinase-1 (TBK1), activated nuclear factor-κB (NF-κB), interferon-γ (IFN-γ) and tumor necrosis factor-α (TNF-α) in the intestinal mucosa were assayed. LPS responsiveness with or without SST pretreatment was assayed in vitro by quantification of TLR4, TBK1, activated NF-κB, IFN-γ and TNF-α in isolated intestinal epithelia. Mucosal damage was observed in the ethanol group by light and electron microscopy. Escherichia coli cultures were unchanged in rat intestine of the ethanol group compared with controls, but lactobacilli cultures were reduced (p < 0.05). LPS levels increased in peripheral and portal venous plasma (p < 0.05), but mucosal TLR4, TBK1, nuclear NF-κB, IFN-γ and TNF-α were unchanged in the ethanol group. LPS treatment in vitro up-regulated the level of TLR4, TBK1 and nuclear NF-κB as well as the production of IFN-γ and TNF-α in isolated intestinal epithelia in the control (p < 0.05), but not the ethanol group. The stimulatory effects of LPS on intestinal epithelia isolated from the control group were significantly inhibited by SST pretreatment (p < 0.05). The peripheral plasma and intestinal levels of SST and the mucosal expression of SSTR2 in the ethanol group were significantly higher than in the control group (p < 0.05). These findings suggest the hyposensitivity of intestinal epithelial TLR4 to LPS induced by acute alcohol abuse probably through ethanol per se and ethanol-enhanced intestinal mucosal SST pathway may be a novel mechanism for increased susceptibility to intestinal pathogens.     

Variation of growth in the production of the BCG vaccine and the association with the immune response. An observational study within a randomised trial

IntroductionBacille Calmette–Guérin (BCG) vaccine has beneficial non-specific effects on overall survival. After BCG vaccination, positive PPD response and scar formation are associated with increased survival. During a trial randomising low-birth-weight neonates to BCG at birth or the usual delayed BCG, the manufacturer of the BCG vaccine experienced a period with relatively slow growth rate of the BCG. We investigated the association between growth rate of BCG when manufacturing the vaccine and its capability to induce immune responses in vivo and in vitro.Methods1633 neonates were randomised to BCG at birth and examined for scar at 12 months; a subgroup was tested for PPD response at 2 and 6 months. The BCG batches from the Slow growth period were compared with the precedent and subsequent Normal growth batches with regard to prevalence and size of BCG scar and PPD response. We also tested the effect of batches on in vitro cytokine responses.ResultsAt 12 months, the Slow growth batches were associated with higher BCG scar prevalence (98.2%) than the precedent batches (92.3%, p = 0.01) but the prevalence remained high after return to normal growth (98.8%, p = 0.52). The Slow growth batches were associated with larger scar size (5.0 mm) than precedent (4.4 mm, p < 0.01) and subsequent batches (4.8 mm, p = 0.03). Compared with Normal growth batches, the Slow growth batches were associated with a higher prevalence of positive PPD responses, and among PPD positive children, a larger PPD reaction (geometric mean ratio: 1.40 (1.20–1.63)) at 2 months. In response to secondary heterologous stimulation, monocytes primed with Slow growth batches induced higher IL-6 (p = 0.03) and TNF-α responses (p = 0.03) compared with Normal growth batches.ConclusionThe study indicates that variations in the production of BCG vaccine may influence important immunological effects of the vaccine.Trial registrationclinicaltrials.gov (NCT00625482).     

Effects of home-based Voluntary Counselling and Testing on HIV-related stigma: Findings from a cluster-randomized trial in Zambia

HIV-related stigma continues to be a prominent barrier to testing, treatment and care. However, few studies have investigated changes in stigma over time and the factors contributing to these changes, and there is no evidence of the impact of HIV testing and counselling on stigma. This study was nested within a pair-matched cluster-randomized trial on the acceptance of home-based voluntary HIV counselling and testing conducted in a rural district in Zambia between 2009 and 2011, and investigated changes in stigma over time and the impact of HIV testing and counselling on stigma. Data from a baseline survey (n = 1500) and a follow-up survey (n = 1107) were used to evaluate changes in stigma. There was an overall reduction of seven per cent in stigma from baseline to follow-up. This was mainly due to a reduction in individual stigmatizing attitudes but not in perceived stigma. The reduction did not differ between the trial arms (β = −0.22, p = 0.423). Being tested for HIV was associated with a reduction in stigma (β = −0.57, p = 0.030), and there was a trend towards home-based Voluntary Counselling and Testing having a larger impact on stigma than other testing approaches (β = −0.78, p = 0.080 vs. β = −0.37, p = 0.551), possibly explained by a strong focus on counselling and the safe environment of the home. The reduction observed in both arms may give reason to be optimistic as it may have consequences for disclosure, treatment access and adherence. Yet, the change in stigma may have been affected by social desirability bias, as extensive community mobilization was carried out in both arms. The study underscores the challenges in measuring and monitoring HIV-related stigma. Adjustment for social desirability bias and inclusion of qualitative methods are recommended for further studies on the impact of HIV testing on stigma.     

Hepatitis B vaccination uptake and correlates of serologic response among HIV-infected and uninfected men who have sex with men (MSM) in Bangkok,Thailand

BackgroundVaccination against hepatitis B virus (HBV) is recommended for all HBV-susceptible men who have sex with men (MSM). There is limited information on correlates of immunity to HBV vaccination in this group. We present serologic response rates to hepatitis B vaccine and identify factors associated with impaired response among HIV-uninfected and HIV-infected Thai MSM.MethodologyHBV-susceptible volunteers were offered hepatitis B vaccination at months zero, one, and six. We measured baseline (pre-vaccination) total serum IgG and IgG subclasses (all participants), baseline CD4 count, and plasma HIV-1 viral load (PVL) (HIV+ participants). HBV serologies were retested at 12 months. Serologic responses were compared between all groups in men receiving three vaccine doses.Results511/651 HIV-negative and 64/84 HIV-positive participants completed the three-dose series. Response rates in HIV-uninfected and -infected participants were 90.1% vs. 50.0% (p < 0.0001). Median pre-vaccination IgG was higher among non-responders than responders overall (1238.9.0 vs. 1057.0 mg/dL, p = 0.003) and among HIV-infected participants (1534.0 vs. 1244.5 mg/dL, p = 0.005), but not significantly among HIV-uninfected participants (1105.5 vs. 1054.3 mg/dL, p = 0.96). Pre-vaccination IgG1 and IgG3 levels were higher among HIV-positive than HIV-negative participants (median 866.0 vs. 520.3, and 105.8 vs. 83.1 mg/dL, respectively, p < 0.0001). Among HIV-infected participants, median CD4 count in non-responders was 378 cells/μL vs. 431 cells/μL in responders (p = 0.20). Median PVL in non-responders was 64,800 copies/mL vs. 15500 copies/mL in responders (p = 0.04). Participants with pre-vaccination plasma IgG >1550 mg/dL and PVL >10,000 copies/mL were almost always non-responsive (p < 0.01).ConclusionsHIV infection was associated with poor vaccine responses. High plasma viral load, elevated pre-vaccination total serum IgG and elevated pre-vaccination IgG1 are associated with poorer response to vaccination among HIV-infected MSM. In this group, the combination of high PVL and pre-vaccination total IgG is highly predictive of vaccine failure.     

An assessment of a TNF polymorphic marker for the risk of HCV infection: Meta-analysis and a new clinical study design

A number of studies have investigated the association between TNF-α ?308G/A polymorphism and the risk of HCV infection; the results of these studies are conflict, however. To provide a more definitive conclusion, a meta-analysis combining and summarizing 12 studies was performed. The Mantel–Haenszel and DerSimonian–Laird methods were employed in traditional fixed effects and random effects meta-analysis, respectively. The capability of a Bayesian approach was highlighted in the estimation of a pooled odds ratio and 95% confidence interval, as well as in the calculation of a sample size for the new study design. Heterogeneity and publication bias across the studies were also explored. The results of the meta-analysis (OR = 1.179, CI = 0.833–1.649) suggest no significant association between TNF-α ?308G/A polymorphism and susceptibility to HCV infection in the combined populations. However, there was evidence indicating a possible impact of ethnicity (Asian vs. non-Asian populations) on the association evaluated here (β_ethnicity = 0.293 ± 0.271). While the power of existing Asian studies was insufficient to make a statistical statement, the sample size of a new clinical study was estimated (500 subjects with 80% statistical power) for further assessment of an association between TNF-α ?308G/A polymorphism and risk of HCV infection in Asians.     

Introduction of telemedicine for medication abortion: Changes in service delivery patterns in two U.S. states

Objective(s)Telemedicine for medication abortion (teleMAB) is safe and effective, yet little is known about how its introduction affects service delivery. We assessed changes in service delivery patterns 1 year after introducing teleMAB at Planned Parenthood in 2 U.S. states.Study DesignRetrospective records analysis using electronic health record data from Planned Parenthood health centers in Montana and Nevada from 2015 to 2018. We included all patients receiving medication or aspiration abortion in the year before and after introducing site-to-site teleMAB. Outcomes included: the proportion of medication abortions (vs. aspiration); gestational age at abortion; time to appointment; and distance traveled. We compared outcomes pre- and postimplementation using χ², t tests, and Mann-Whitney U tests.ResultsWe analyzed data for 3,038 abortions: 1,314 pre- and 1,724 postimplementation. In Montana, the proportion of medication abortions increased postimplementation (60% vs. 65%, p = 0.04). Mean gestational age was similar: 58 versus 57 days (p = 0.35). Mean time to appointment decreased (14 vs. 12 days, p < 0.0001), as did one-way distance traveled by patients (134 vs. 115 miles, p = 0.03). In Nevada, where Planned Parenthood only provided medication abortion, total medication abortions increased (461 vs. 735). Mean gestational age remained stable (51 vs. 51 days, p = 0.33), as did time to appointment (8 vs. 8 days, p = 0.76). Mean one-way distance traveled was 47 miles in the preperiod versus 34 miles in the postperiod (p = 0.22).Conclusion(s)Medication abortion increased after the introduction of telemedicine in both states, though we cannot account for abortions performed by other providers. Telemedicine has the potential to improve access to medication abortion.ImplicationsTelemedicine has the potential to improve or maintain access to medication abortion and should be taken to scale where feasible. Continued efforts are needed to mitigate or reverse policy restrictions on telemedicine for medication abortion.     

Racial and socioeconomic disparities in viral suppression among persons living with HIV in New York City

PurposeTo examine differences in racial disparities across levels of neighborhood poverty and differences in socioeconomic disparities by race/ethnicity in viral suppression among persons living with HIV (PLWH).MethodsUsing HIV surveillance data, we categorized and geocoded PLWH who were in care in New York City (NYC). Multilevel binomial regression techniques were used to model viral suppression with a two-level hierarchical structure, by including age, transmission risk, year of diagnosis, race/ethnicity, census tract poverty, and an interaction term of race/ethnicity and census tract poverty in the model.ResultsThere were 30,638 Blacks, 22,921 Hispanics, and 11,695 Whites living with HIV and retained in care in NYC, 2014. Compared with Blacks living in the most impoverished neighborhoods (≥30% residents living below the federal poverty level) who had the lowest proportion of viral suppression, with 75% in males and 76% in females, Whites living in the least impoverished neighborhoods (<10% residents living below the federal poverty level) had the highest, with 92% in males (prevalence ratio = 1.16; 95% confidence interval: 1.13, 1.18) and 90% in females (PR = 1.14; 95% CI: 1.09, 1.19).ConclusionsBy examining racial and socioeconomic disparities simultaneously, we were able to detect both disparities in viral suppression among PLWH in NYC.     

Predictors of serological non-response to the 13-valent pneumococcal conjugate vaccine followed by the 23-valent polysaccharide vaccine among adults living with HIV

BackgroundPeople living with HIV (PLWH) have higher incidence of pneumococcal disease compared to people without HIV. Immunization with pneumococcal vaccines is recommended, but serological non-response to pneumococcal vaccination is common for largely unknown reasons.MethodsPLWH on antiretroviral treatment and no prior pneumococcal vaccination received the 13-valent pneumococcal conjugate vaccine (PCV13) followed 60 days later by the 23-valent polysaccharide vaccine (PPV23). Serological response was evaluated 30 days post-PPV23 by antibodies against 12 serotypes covered by both PCV13 and PPV23. Seroprotection was defined as a ≥2-fold rise to a level above 1.3 µg/ml in geometric mean concentration (GMC) across all serotypes. Associations with non-responsiveness were evaluated by logistic regression.ResultsFifty-two virologically suppressed PLWH (median age of 50 years (IQR 44–55) and median CD4 count of 634 cells/mm³ (IQR 507–792)) were included. Forty-six percent (95 % CI 32–61, n = 24) achieved seroprotection. Serotypes 14, 18C and 19F had the highest, and serotypes 3, 4 and 6B the lowest GMCs. Pre-vaccination GMC levels less than 100 ng/ml were associated with increased odds of non-responsiveness compared to levels above 100 ng/ml (adjusted OR 8.7, 95 % CI 1.2–63.6, p = 0.0438).ConclusionLess than half of our study population achieved anti-pneumococcal seroprotective levels following PCV13 and PPV23 immunization. Low pre-vaccination GMC levels were associated with non-response. Further research is required to optimize vaccination strategies that achieve higher seroprotection in this high-risk group.     

Knowledge,Attitudes, and Sexual Behaviors in HIV/AIDS and Predictors Affecting Condom Use among Men Who Have Sex with Men in South Korea

ObjectivesIn South Korea, men who have sex with men (MSM) are rather understudied, but are known to be at high risk for human immunodeficiency virus infection (HIV)/acquired immunodeficiency syndrome (AIDS). This study was to access HIV/AIDS knowledge, attitudes, and risk behaviors, and to identify the factors of condom use in HIV prevention.MethodsWe recruited 1070 MSM in Korea, using the Internet to maximize the confidentiality of the MSM.ResultsThe prevalence of self-reported and sexually transmitted infections and HIV in the total sample was 10.7% and 2.7%, respectively. Factual knowledge and phobias regarding HIV/AIDS and self-efficacy were relatively high among the MSM. After controlling for age, education, marital status, and sexual identity, predictors of condom use at most recent anal sex included knowledge (OR = 1.25; p < 0.0001); self-efficacy (OR = 1.33; p = 0.02), additionally, having HIV testing (OR = 1.45; p = 0.02); and having a regular partner (OR = 0.53; p < 0.0001) were also positively associated with condom use.ConclusionThe intervention programs for MSM in Korea may need to take the idiosyncratic societal and cultural pressures of the region into consideration in order to reduce infection risk.     

Perinatal Depression and Anxiety in Women with and without Human Immunodeficiency Virus Infection

BackgroundUntreated depression and anxiety during the perinatal period have significant consequences on maternal and infant health; however, few studies have examined perinatal depression and perinatal anxiety in women with human immunodeficiency virus (HIV) infection. The current study prospectively examined the prevalence of prenatal and postpartum depression and anxiety, and emotional support from family and friends, as well as childhood sexual abuse in women with and without HIV infection.MethodsBetween July 2009 and January 2013, 258 pregnant women receiving care in a Philadelphia hospital were enrolled, with 162 completing both the prenatal and postpartum portions of the study. The Center for Epidemiological Studies–Depression Scale (CES-D), and the State-Trait Anxiety Inventory for Adults were used to measure depression and anxiety symptoms, respectively. An independent samples t test and multiple linear regressions were used to determine associations among depression, anxiety, and pregnancy-related variables.ResultsForty-nine participants (30%) were living with HIV; 113 (70%) were HIV negative. CES-D scores did not differ prenatally (p = .131) or postpartum (p = .156) between women with and without HIV. Prenatal state anxiety scores were higher in women with HIV (p = .02) but there were no differences postpartum (p = .432). In a multiple linear regression, trait anxiety predicted postpartum anxiety in the full sample (p < .001) and childhood sexual abuse predicted postpartum depression among women with HIV (p = .021).ConclusionsThese findings highlight the importance of identifying and treating perinatal depression and anxiety early in the prenatal period. Results also emphasize the need for providers to be aware of childhood sexual abuse as a potential correlate for depression in women with HIV.     

Clinical and immunologic predictors of influenza illness among vaccinated older adults

The diagnosis of influenza is often missed in older adults and illness presentation may be modified by prior vaccination. We evaluated the symptoms and immunologic markers predicting laboratory-confirmed influenza (LCI) among vaccinated older adults. In subjects with influenza-like illness (ILI), fever distinguished subjects with laboratory-confirmed influenza (LCI) from those with other ILI (39% vs. 12.5%, p = 0.009). In LCI subjects who did not seroconvert to influenza infection, pre-infection levels of the cytolytic mediator, granzyme B, correlated with fever (r = 1.000; p = 0.01) and the IFN-γ:IL-10 ratio (r = 0.999; p = 0.03), and increased following influenza infection in LCI vs. ILI subjects (p = 0.03). The cell-mediated immune response to influenza distinguishes A/H3N2 LCI from other ILI in older adults, and suggests a link between cell-mediated immunity and influenza illness severity in vaccinated older adults.     

Association between TLR3 rs3775291 and resistance to HIV among highly exposed Caucasian intravenous drug users

BackgroundTLR3 recognizes dsRNA and triggers immune responses against RNA and DNA viruses. A polymorphism in TLR3, rs3775291 (Leu412Phe), has been associated with the increased susceptibility to enteroviral myocarditis, protection against tick-borne encephalitis virus and HIV-1 infection. We investigated Caucasian intravenous drug users (IDUs) and blood donors in order to evaluate the associations between TLR3 genotypes and susceptibility to HIV infection.Materials and methodsA total of 345 Caucasian IDUs were recruited, 50% of them were HIV positive, 89% HCV and 77% HBV positive. Based on their history of needle sharing, 20 of the HIV negative IDUs were classified as highly exposed HIV seronegatives (HESNs), 68 as non-HESNs and 85 as unexposed. The control group consisting of 497 blood donors tested negative for all three viruses. TLR3 rs3775291 were determined by using TaqMan Allelic Discrimination Assay.ResultsThe TLR3 rs3775291 T allele frequency was similar among the HIV negative and HIV positive IDUs and blood donors – 36%, 31% and 34%, respectively. The frequency of persons possessing at least one TLR3 rs3775291 T allele was significantly higher in HESNs compared with blood donors and HIV positive IDUs (80% vs. 55%; p = 0.037 and 80% vs. 53%; p = 0.031, respectively). In the univariate analysis, persons who possessed at least one T allele had reduced odds of being HIV seropositive (OR = 0.29, 95% CI = 0.09–0.90). This association remained significant (OR = 0.25, 95% CI = 0.07–0.87) after the adjustment for other co-variates (HCV, HBV serostatus and duration of intravenous drug use).ConclusionsThe TLR3 rs3775291 T allele has a protective effect against HIV infection among HESNs IDUs.     

Factors of loss to follow-up during tuberculosis treatment in a low-incidence region

ObjectiveThe proportion of successfully treated tuberculosis (TB) patients remains below the WHO target in France, because of a high proportion of loss to follow-up. We aimed to identify factors associated with loss to follow-up in northern France, a low-incidence area.MethodsBetween 1997 and 2017, all consecutive patients diagnosed with TB at the Tourcoing Hospital, except those infected with multidrug-resistant or extensively drug-resistant strains, were included in a retrospective cohort study. A logistic regression analysis was performed to determine factors associated with loss to follow-up.ResultsOne hundred and ninety patients were included. Previous TB treatment was reported in 32 patients (17%), extrapulmonary TB in 107 (56%), and HIV infection in 44 (23%). The proportion of loss to follow-up was 15%. In multivariate analysis, the risk of loss to follow-up decreased in case of first TB treatment (OR 0.36; 95% CI: 0.14–0.92, P = 0.03) and increased in non-HIV-infected patients (OR 7.67; 95% CI: 1.00–59.0, p = 0.05). Support for compliance was more frequent in HIV-infected patients (23% vs. 7%, p = 0.005).ConclusionThe proportion of loss to follow-up was high. HIV infection was associated with a lower risk of loss to follow-up, likely to be due to more frequent support for compliance.
