High burden of hepatitis C & HIV co-infection among people who inject drugs in Manipur, Northeast India.

BACKGROUND & OBJECTIVES: It is well documented that the Northeast state of Manipur in India has been dealing with the dual problems of injecting drug use and HIV for the last two decades, but the hepatitis C problem has not been so well characterized. The aim of this study was to assess the prevalence of hepatitis C virus (HCV) infection and HCV/HIV co-infection among people who inject drugs (PWID) in Manipur, and identify factors associated with infection. METHODS: Data were obtained from the Integrated Behavioural and Biological Assessment (2009-2010), a cross-sectional survey among 821 male PWID in two districts of Manipur (Churachandpur and Bishnupur). Information about drug use, sexual and injecting risk behaviours, and exposure to interventions was obtained, and biological specimens tested for HIV and HCV. Logistic regression analyses identified factors associated with HCV infection and HCV/HIV co-infection. RESULTS: HCV prevalence was 74 per cent (91% Churachandpur, 56% Bishnupur), and HCV/HIV co-infection was 29 per cent (38% Churachandpur, 21% Bishnupur). Among the 31 per cent of HIV positive PWID, 95 per cent were co-infected. HCV infection was associated with district, longer duration of injecting, injecting at least once daily, generally injecting with a used needle and syringe, and having had an HIV test. HCV/HIV co-infection was associated with district, older age, being employed, being widowed/divorced, longer duration of injecting, and feeling at risk of HIV infection. INTERPRETATION & CONCLUSIONS: The HCV/HIV co-infection among PWID in Manipur was very high, highlighting the urgent need for effective prevention, diagnosis and treatment.

Injecting drug use in Manipur and Nagaland, Northeast India: injecting and sexual risk behaviours across age groups.

BACKGROUND: There is an HIV epidemic among people who inject drugs (PWID) in Manipur and Nagaland, Northeast India. Approximately one-third of PWID across these two states are aged below 25 years, yet until now there has been no systematic investigation of the differences between the younger and older PWID. We sought to profile differences in drug use and sexual practices across age groups and to examine whether age is associated with injecting and sexual risk behaviours. METHODS: We used combined cross-sectional survey data collected in 2009 from two surveys involving a total of 3,362 (male) PWID in eight districts of Manipur and Nagaland. All data were collected using interviewer-administered questionnaires. RESULTS: Compared to PWID aged 35 years or older, PWID aged 18 to 24 years were more likely share needles/syringes in both Manipur (OR =1.8) and Nagaland (OR =1.6). Compared to PWID aged 35 years or older, PWID aged 18 to 24 years were almost two times as likely to draw up drug solution from a common container at their last injection in Manipur (OR =1.8). In Nagaland, PWID aged 18 to 24 years were more likely to use condoms consistently with both casual (OR =3.1) and paid (OR =17.7) female sexual partners compared to PWID aged 35 years or older. CONCLUSION: Risky injecting practices were more common among younger PWID in both Manipur and Nagaland, while unprotected sex was more common among older PWID in Nagaland. There is a clear need to focus public health messages across different age groups.

Quality of life, depression, anxiety and suicidal ideation among men who inject drugs in Delhi, India.

BACKGROUND: Mental disorders such as depression, anxiety and suicide represent an important public health problem in India. Elsewhere in the world a high prevalence of symptoms of common mental disorders have been found among people who inject drugs (PWID). Research in India has largely overlooked symptoms of common mental disorders among this high risk group. This paper reports on the results of a survey examining quality of life, depression, anxiety and suicidal ideation among adult males who inject drugs living in Delhi. METHODS: Participants (n = 420) were recruited from needle and syringe programs using time location sampling and were interviewed using an interviewer-administered questionnaire. Self-report symptom scales were used to measure the severity of symptoms of depression (PHQ-9) and anxiety (GAD-2) within the preceding 2 weeks. We assessed the presence of suicidal thoughts and attempts within the past 12 months. RESULTS: The mean length of injecting career was 20.9 years indicating a sample of chronic injecting drug users, of whom only one-third (38%) were born in Delhi. The level of illiteracy was very high (62%), and just 2% had completed class 12. Scavenging / rag picking was the main form of income for 48%, and many were homeless (69%). One-third (33%) had been beaten up at least twice during the preceding 6 months, and many either never (45%) or rarely (27%) attended family events. We found a high prevalence of depressive (84%, cut-off ≥10) and anxiety (71%, cut-off score of ≥3) symptoms. Fifty-three percent thought about killing themselves in the past 12 months, and 36% had attempted to kill themselves. CONCLUSIONS: Our findings revealed a socially excluded population of PWID in Delhi who have minimal education and are often homeless, leaving them vulnerable to physical violence, poverty, poor health, imprisonment and disconnection from family. The high prevalence of psychological distress found in this study has implications for programmes seeking to engage, treat and rehabilitate PWID in India.

Test and Treat Model for Tuberculosis Preventive Treatment among Household Contacts of Pulmonary Tuberculosis Patients in Selected Districts of Maharashtra: A Mixed-Methods Study on Care Cascade, Timeliness, and Early Implementation Challenges.

Tuberculosis preventive treatment (TPT) is an important intervention in preventing infection and reducing TB incidence among household contacts (HHCs). A mixed-methods study was conducted to assess the "Test and Treat" model of TPT care cascade among HHCs aged ≥5 years of pulmonary tuberculosis (PTB) patients (bacteriologically/clinically confirmed) being provided TPT care under Project Axshya Plus implemented in Maharashtra (India). A quantitative phase cohort study based on record review and qualitative interviews to understand the challenges and solutions in the TPT care cascade were used. Of the total 4181 index patients, 14,172 HHCs were screened, of whom 36 (0.3%) HHCs were diagnosed with tuberculosis. Among 14,133 eligible HHCs, 10,777 (76.3%) underwent an IGRA test. Of them, 2468 (22.9%) tested positive for IGRA and were suggested for chest X-ray. Of the eligible 2353 HHCs, 2159 (91.7%) were started on TPT, of whom 1958 (90.6%) completed the treatment. The median time between treatment initiation of index PTB patient and (a) HHC screening was 31 days; (b) TPT initiation was 64 days. The challenges in and suggested solutions for improving the TPT care cascade linked to subthemes were tuberculosis infection testing, chest X-ray, human resources, awareness and engagement, accessibility to healthcare facilities, TPT drugs, follow-up, and assessment. A systematic monitoring and time-based evaluation of TPT cascade care delivery followed by prompt corrective actions/interventions could be a crucial strategy for its effective implementation and for the prevention of tuberculosis.

Association of depression, anxiety, and suicidal ideation with high-risk behaviors among men who inject drugs in Delhi, India.

BACKGROUND: Sharing of needles and syringes and unprotected sex remain a common practice among people who inject drugs (PWID) in India and are important drivers of new HIV infections. Whether engagement in risk behaviors among PWID is associated with symptoms of common mental disorders in India is unknown. METHODS: We analyzed the data collected in April and May of 2012 from a community-based sample of 420 PWID in Delhi using time location sampling. Self-report symptom scales were used to measure the severity of symptoms of depression (Patient Health Questionnaire 9) and anxiety (Generalized Anxiety Disorder scale 2) within the preceding 2 weeks. We assessed the presence of suicidal thoughts within the past 12 months. RESULTS: PWID with severe depressive symptoms and those with suicidal thoughts were 4 and 2 times more likely to share needles/syringes, respectively. PWID experiencing suicidal thoughts had 82% more female sexual partners and were 5 times more likely to have had unprotected sex at last sex with a paid female partner. Conversely, symptoms of anxiety were associated with a 30% decrease in the likelihood of needle/syringe sharing and a 70% decrease in the likelihood of unprotected sex at last sex with a paid female partner. CONCLUSIONS: We found a high prevalence of symptoms of depression, anxiety, and suicidal ideation among men who inject drugs in Delhi and that depression and suicidal ideation are independently positively associated with HIV risk behaviors, whereas anxiety is associated with a reduction in such behaviors. Ameliorating mental health problems among PWID in India may aid in reducing HIV infections.

Alcohol and condom use among HIV-positive and HIV-negative female sex workers in Nagaland, India.

This study examines the relationship between alcohol use, HIV status, and condom use among female sex workers in Nagaland, India. We analyzed data from a cross-sectional survey undertaken in 2009, using descriptive and multivariate statistics. Out of 417 female sex workers, one-fifth used alcohol daily and one-tenth were HIV-positive. HIV-positive female sex workers were more likely than HIV-negative female sex workers to consume alcohol daily (30.2% vs. 18.0%). HIV-positive daily alcohol users reported lower condom use at last sex with regular clients compared to HIV-positive non-daily alcohol users (46.2% vs. 79.3%), a relationship not evident among HIV-negative female sex workers. There is a need to promote awareness of synergies between alcohol use and HIV, and to screen for problematic alcohol use among female sex workers in order to reduce the spread of HIV.
