Perceived need, barriers to and facilitators of mental health care among HIV-infected PWID in Hanoi, Vietnam: A qualitative study

Background: The HIV epidemic in Vietnam has been primarily driven by injection drug use. HIV-infected people who inject drugs (PWID) in Vietnam have very high rates of mental health problems, which can accelerate progression to AIDS and increase mortality rates. No research has explored the barriers and facilitators of mental health care for HIV-infected PWID in Vietnam. Methods: We conducted 28 in-depth interviews among HIV-infected PWID (n = 16), HIV and MMT (methadone maintenance treatment) providers (n = 8), and health officials (n = 4) in Hanoi. We explored participants' perceptions of mental health disorders, and barriers and facilitators to seeking and receiving mental health care. Results: HIV-infected PWID were perceived by both PWID, HIV/MMT providers, and health officials to be vulnerable to mental health problems and to have great need for mental health care. Perceived social, physical, and economical barriers included stigma towards HIV, injection drug use, and mental illnesses; lack of awareness around mental health issues; lack of human resources, facilities and information on mental health services; and limited affordability of mental health services. Social support from family and healthcare providers was a perceived facilitator of mental health care. Conclusions: Interventions should raise self-awareness of HIV-infected PWID about common mental health problems; address social, physical, economic barriers to seeking mental health services; and increase social support for patients

Examining common mental health disorders in people living with HIV on methadone maintenance therapy in Hanoi, Vietnam

Background: Injection drug use drives HIV transmission in Southeast Asia, where around a quarter of users are living with HIV. Vietnam developed Methadone Maintenance Therapy (MMT) programs to reduce unsafe drug abuse. Common mental health disorders (CMD), including depression, anxiety and post-traumatic stress disorder (PTSD), can worsen MMT outcomes and are highly prevalent among people living with HIV (PLH). We aimed to characterize HIV and CMD among MMT patients and assess the impact of HIV and CMD on MMT engagement outcomes in Hanoi, Vietnam. Methods: This cross-sectional study was conducted at an urban MMT clinic in Hanoi. Participants were screened for CMD with the relevant sections of the Mini International Neuropsychiatric Interview (MINI). Tabular comparisons and regression models were used to understand the association of HIV and CMD with substance use and methadone compliance. Results: Of the 400 MMT participants, 22% were living with HIV, 11% a CMD, 27% reported injection drug use, and 27% reported methadone noncompliance. Around 17% of those with HIV also had a CMD. Reporting non injection and injection drug use were each higher among those with CMD regardless of HIV status. In addition, reporting any drug use was much higher among those with both HIV and CMD than among those with neither (73% vs 31%, p value 0.001). While methadone noncompliance was lower among PLH than among those without HIV (16.3% vs 30.1%, p value 0.010), noncompliance was higher among those with CMD than among those without (40.5% vs 25.6%, p value 0.045). Among those without HIV, noncompliance was higher among those with CMD than among those without, but among those with HIV, the opposite relationship was observed. Conclusion: There is complex overlap between substance use and methadone noncompliance among MMT patients living with HIV, CMD or both. In this population, we found a high prevalence of CMD and substance use among PLH, and a high prevalence of substance use and methadone noncompliance among those with CMD. Prioritizing provision of mental health care services to MMT patients living with HIV can help improve engagement with substance use disorder treatment and reduce the risk of HIV transmission

Validation of screening tools for common mental health disorders in the methadone maintenance population in Hanoi, Vietnam

Background: Common mental health disorders (CMDs), including depression, anxiety and post-traumatic stress disorder (PTSD) may worsen both HIV and drug use outcomes, yet feasible tools to accurately identify CMDs have received limited study in this population. We aimed to validate the Patient Health Questionnaire (PHQ-9), Generalized Anxiety Disorder screen (GAD-7) and Primary Care PTSD screen for DSM-5 (PC-PTSD-5) in a methadone maintenance therapy (MMT) patient population in Hanoi, Vietnam. Methods: We conducted a cross-sectional survey. The PHQ-9, GAD-7, and PC-PTSD-5 were administered to MMT patients. A blinded interviewer administered the Mini-International Neuropsychiatric Interview (MINI) as the reference gold standard. Total scores of each tool were compared with the MINI diagnoses using a receiver operating characteristic curves, and we identified the optimal respective cut-off scores using the Youden’s Index. Results: We enrolled 400 MMT patients. Approximately 99.3% were male (n = 397) and 21.8% (n = 87) were HIV positive. The prevalence of major depressive disorder, generalized anxiety disorder and PTSD, respectively, was 10.5, 4 and 2%. Optimal cut-off scores for the PHQ-9, GAD-7 and PC-PTSD were ≥ 5, ≥3, and ≥ 4 with a sensitivity/specificity of 95.2%/91.9, 93.8%/87.5, and 62.5%/95.2%. Conclusions: The prevalence of CMDs in the MMT population was lower than expected. A lower cut-off score may be considered when screening for CMDs in this population. Further research should investigate the validity of somatic symptom-based screening tools among other drug-using or MMT populations

Psychometric performance of the perceived stigma of substance abuse scale (PSAS) among patients on methadone maintenance therapy in Vietnam

Background: People who inject drugs (PWID) and patients on methadone maintenance therapy (MMT) face severe stigma and discrimination. However, there are limited measures assessing stigma towards individuals with substance use disorders or MMT patients, particularly in Vietnam, and few studies have examined the psychometric properties of existing measures. This study aims to examine the performance of the eight-item Perceived Stigma of Substance Abuse Scale (PSAS), created in the United States, among a population of MMT patients in Vietnam. Methods: A cross-sectional survey was conducted among 400 adult patients enrolled in an urban MMT clinic. Substance use stigma was measured using the PSAS. We conducted confirmatory factor analysis (CFA) and assessed construct validity, reliability and known-group validity. Results: The original eight-item scale was unidimensional, but yielded mixed goodness-of-fit indicators. Ultimately, dropping two items and allowing the errors of the items related to childcare to correlate improved the goodness-of-fit indicators. (RMSEA = 0.025; CFI = 0.999; and SRMR = 0.018). The shortened scale demonstrated acceptable reliability (Cronbach's α = 0.766). The mean stigma scores were significantly higher among individuals not working, but did not significantly vary by length of time in MMT, marital status, education attainment, HIV status, depression, concurrent injection drug use or missed methadone dose. Conclusions: The shortened six-item scale demonstrated good construct validity and acceptability reliability, but it did not demonstrate many a priori hypothesized known-group validity associations. Further research should consider a mixed-methods validation approach

What is the best drug treatment for premenopausal women with bleeding irregularities using the levonorgestrel-releasing intrauterine system? A systematic review

Objective Up to 60% of women discontinue using the levonorgestrel-releasing intrauterine system (LNG-IUS) within 5 years because of bleeding irregularities, pain and/or systemic progestogenic adverse effects. The aim of the study was to assess treatment options for bleeding irregularities in women using the 52 mg LNG-IUS. Methods Database searches of Medline, Embase/Ovid and the Cochrane Library were carried out, and journals were searched by hand, for relevant studies published from database inception to March 2020. Inclusion criteria were randomised controlled trials (RCTs), prospective cohort studies and case-control studies of premenopausal women using the LNG-IUS and receiving medical treatment for bleeding irregularities. Screening, data extraction and quality assessment of retrieved articles were carried out independently by two pairs of reviewers. The primary outcome was the reduction of bleeding/spotting days. Results Of the 3061 studies identified, eight met our inclusion criteria: six RCTs and two prospective cohort studies. The eight studies enrolled a total of 677 women who were treated with tamoxifen, mifepristone, ulipristal acetate, naproxen, oestradiol, mefenamic acid, tranexamic acid or the progesterone receptor modulator CDB 2914. The results of our analysis indicated that naproxen may be effective for the prophylactic treatment of bleeding immediately (6 months after insertion (low level of evidence). Conclusion Evidence for the medical treatment of (ongoing) bleeding irregularities during use of the LNG-IUS is lacking and more research is needed on the topic

The endometrial microbiota of women with or without a live birth within 12 months after a first failed IVF/ICSI cycle.

The endometrial microbiota composition may be associated with implantation success. However, a 'core' composition has not yet been defined. This exploratory study analysed the endometrial microbiota by 16S rRNA sequencing (V1-V2 region) of 141 infertile women whose first IVF/ICSI cycle failed and compared the microbiota profiles of women with and without a live birth within 12 months of follow-up, and by infertility cause and type. Lactobacillus was the most abundant genus in the majority of samples. Women with a live birth compared to those without had significantly higher Lactobacillus crispatus relative abundance (RA) (p = 0.029), and a smaller proportion of them had ≤ 10% L. crispatus RA (42.1% and 70.4%, respectively; p = 0.015). A smaller proportion of women in the male factor infertility group had ≤ 10% L. crispatus RA compared to women in the unexplained and other infertility causes groups combined (p = 0.030). Women with primary infertility compared to secondary infertility had significantly higher L. crispatus RA (p = 0.004); lower proportions of them had ≤ 10% L. crispatus RA (p = 0.009) and > 10% Gardnerella vaginalis RA (p = 0.019). In conclusion, IVF/ICSI success may be associated with L. crispatus RA and secondary infertility with endometrial dysbiosis, more often than primary infertility. These hypotheses should be tested in rigorous well-powered longitudinal studies
