Alcohol use disorders (AUD) among tuberculosis patients: a study from Chennai, South India.

BACKGROUND: Alcohol Use Disorders (AUDs) among tuberculosis (TB) patients are associated with nonadherence and poor treatment outcomes. Studies from Tuberculosis Research Centre (TRC), Chennai have reported that alcoholism has been one of the major reasons for default and mortality in under the DOTS programme in South India. Hence, it is planned to conduct a study to estimate prevalence of alcohol use and AUDs among TB patients attending the corporation health centres in Chennai, India. METHODOLOGY: This is a cross-sectional cohort study covering 10 corporation zones at Chennai and it included situational assessment followed by screening of TB patients by a WHO developed Alcohol Use Disorders Identification Test AUDIT scale. Four zones were randomly selected and all TB patients treated during July to September 2009 were screened with AUDIT scale for alcohol consumption. RESULTS: Out of 490 patients, 66% were males, 66% were 35 years and above, 57% were married, 58% were from the low monthly income group of 8. Age (>35 years), education (less educated), income (

Care seeking behavior of chest symptomatics: a community based study done in South India after the implementation of the RNTCP.

INTRODUCTION: With the creation of the Revised National TB Control Programme (RNTCP), tuberculosis services have become decentralized and more accessible. A 1997 study prior to RNTCP implementation reported that most chest symptomatics accessed first private health care facilities and a general dissatisfaction with government health facilities. The study was repeated post-RNTCP implementation to gain insight into the current care seeking behavior of chest symptomatics. METHODOLOGY: A cross-sectional community-based study carried out between March-August 2008 in 4 sites (2 rural [R] and 2 urban [U]) from the same two districts of Chennai and Madurai, southern India, as in the 1997 study. Six hundred and forty chest symptomatics were identified (R 314; U 326), and detailed interviews were done for 606 (R311; U295). RESULTS: Prevalence of chest symptomatics in the urban and rural areas were 2.7% and 4.9% respectively (p<0.01), and was found to increase with age (Chi-square for trend, p<0.01). Longer delays in seeking care were seen amongst symptomatics above 45 years of age (p 0.01), and those who had taken previous TB treatment (p=0.05). Overall, 50% (222/444) of the chest symptomatics approached a government health care facility first (R 142 (61%); U 80 (38%), p=or  <0.001). This was significantly (p<0.001) more than were observed in the 1997 study, where only 38.4% approached a government facility first. Sixty two (28%) of the 222 made a second visit to a government facility (R26%; U31%), while 17% shifted to a private facility (R14%; U21%). Dissatisfaction with the health care facility was one of the major reasons expressed. CONCLUSIONS: It appears that the RNTCP has had an impact in the community with regard to the availability and accessibility of TB services in government health facilities. However the relatively high levels of subsequent shifting to private health facilities calls for urgent action to make government facilities more patients friendly with quality care facilities in the delivery of RNTCP services.

A pilot study on willingness to participate in future preventive HIV vaccine trials.

BACKGROUND & OBJECTIVES: In India, phase-I human clinical trials for a preventive HIV vaccine are being conducted at Pune and Chennai Centres. In order to find out the willingness of populations at risk to participate in future preventive HIV vaccine trials (HIVVTs) and to assess the factors that enhance or deter them from participation, a study was conducted at Chennai and Madurai in Tamil Nadu. METHODS: This cross-sectional study was conducted among transport workers, people attending sexually transmitted infection clinics, injection drug users, men having sex with men, women in sex industry and a representative sample of monogamous married women, by employing measurement scales. A structured questionnaire on knowledge and attitudes about the HIV vaccine was used to measure the participants' knowledge and attitudes about HIV vaccine and HIVVTs. RESULTS: Of the 112 participants, 67 (60%) were men. Mean age of the respondents was 32 yr; 68 per cent were high school educated. Majority of respondents were willing to participate in a future HIVVT and the reasons were altruism, protection from HIV, and support for the researchers. Major concerns were vaccine efficacy, side effects of the vaccine and the impact of a HIV vaccine on the participants' lives. Majority (85%) agreed that sex without condom would not be safe despite the availability of an HIV vaccine. INTERPRETATION & CONCLUSION: It is likely that high-risk volunteers will be willing to enroll in HIVVTs. Barriers and concerns should be dealt with carefully by providing correct information. Also there is a need for more education to ensure participants' understanding of key concepts of HIV vaccine trial.
