RESUMO
BACKGROUND: Active tuberculosis (TB) disease can impose substantial morbidity, while treatment for latent TB infection (LTBI) has frequent side effects. We compared health-related quality of life (HRQOL) between persons diagnosed and treated for TB disease, persons treated for LTBI, and persons screened but not treated for TB disease or LTBI, over one year following diagnosis/initial assessment. METHODS: Participants were recruited at two hospitals in Montreal (2008-2011), and completed the Short Form-36 version 2 (SF-36) at baseline, and at 1, 2, 4, 6, 9, and 12 months thereafter. Eight domain scores and physical and mental component summary (PCS and MCS, respectively) scores were calculated from responses. Linear mixed models were used to compare mean scores at each evaluation and changes in scores over consecutive evaluations, among participants treated for TB disease and those treated for LTBI, each compared to the control group. RESULTS: Of the 263 participants, 48 were treated for TB disease, 105 for LTBI, and 110 were control participants. Fifty-four percent were women, mean age was 35 years, and 90% were foreign-born. Participants treated for TB disease reported significantly worse mean scores at baseline compared to control participants (mean PCS scores: 50.0 vs. 50.7; mean MCS scores: 46.4 vs. 51.1), with improvement in mean MCS scores throughout the study period. Scores reported by participants treated for LTBI and control participants were comparable throughout the study. CONCLUSION: TB disease is associated with decrements in HRQOL as measured by the SF-36. This is most pronounced during the weeks after diagnosis and treatment initiation, but is no longer evident after two months.

PURPOSE: To estimate health utility derived from the Short Form-36 (SF-36) questionnaire and Standard Gamble instrument for persons diagnosed and treated for tuberculosis (TB) disease, those diagnosed and treated for latent TB infection (LTBI), and those screened but not treated for TB disease or LTBI over the year following their diagnosis/initial assessment. METHODS: Participants were recruited at two Montreal hospitals (2008-2011) and completed the SF-36 and Standard Gamble at baseline and at follow-up visits 1, 2, 4, 6, 9, and 12 months thereafter. SF-6D health utility scores were derived from SF-36 responses. Linear mixed models were used to compare mean health utility at each evaluation and changes in health utility between participants treated for TB disease, those treated for LTBI, and those in the control group. RESULTS: Of the 263 participants, 48 were treated for TB disease, 105 for LTBI, and 110 were control participants. Fifty-four percent were women, mean age was 35 years, and 90% were foreign-born. Participants treated for TB disease reported worse health utility compared with control participants at the baseline visit (mean SF-6D: 0.69 vs. 0.81; mean Standard Gamble: 0.64 vs. 0.96). They reported successive improvement at months 1 and 2 that was then sustained throughout follow-up. Health utility reported by participants treated for LTBI and control participants was comparable throughout the study. CONCLUSION: Treatment for TB disease had a substantial negative impact on health utility, particularly during the first 2 months of treatment. However, treatment for LTBI did not have a substantial impact.

The threat of tuberculosis (TB) in Uganda cannot be considered in isolation from the HIV/AIDS epidemic. Stigma contributes to delays in seeking treatment and poor adherence for both TB and HIV patients. This study aims to assess and describe stigma and predictors of stigma related to TB and HIV in the population of western Uganda. This was a cross-sectional mixed methods study. A survey was administered to 360 individuals, randomly selected from one district in western Uganda. Participants were classified as low/high stigma based on weighted scores built from survey questions. Logistic regression was used to determine significant predictors for high stigma. Six focus groups were conducted to inform survey findings; themes were developed using content analysis. Twenty-six per cent of respondents were found to have stigmatising attitudes towards HIV and 47% towards TB. Multivariate logistic regression models included age, sex, marital status, education, residence and having a friend with HIV/TB. Those who had an HIV-positive friend were less likely to have high HIV stigma (OR: 0.41, 95% CI: 0.23-0.72). Those with secondary education or more were half as likely to have high TB stigma (OR: 0.50, 95% CI: 0.27-0.91). Focus group participants felt that "normalisation" of HIV has contributed to reduced HIV stigma, but there is still a fear of being recognised at the HIV clinic. TB stigma causes patients to remain silent instead of seeking care. Fear of TB is driven by the assumption that "TB means HIV". Declining HIV stigma is encouraging but more effort needs to be made to improve confidentiality. TB stigma is high and is likely affecting care seeking behaviour; TB awareness campaigns should be a priority and emphasise the treatability and curability of TB, regardless of HIV status.

BACKGROUND: In Uganda, despite a significant public health burden of tuberculosis (TB) in the context of high human immunodeficiency virus (HIV) prevalence, little is known about community knowledge of TB. The purpose of this study was to assess and compare knowledge about TB and HIV in the general population of western Uganda and to examine common knowledge gaps and misconceptions. METHODS: We implemented a multi-stage survey design to randomly survey 360 participants from one district in western Uganda. Weighted summary knowledge scores for TB and HIV were calculated and multiple linear regression (with knowledge score as the dependant variable) was used to determine significant predictors. Six focus group discussions were conducted to supplement survey findings. RESULTS: Mean (SD) HIV knowledge score was 58 (12) and TB knowledge score was 33 (15), both scores out of 100. The TB knowledge score was statistically significantly (p < 0.001) lower. Multivariate regression models included age, sex, marital status, education, residence, and having a friend with HIV/TB as independent variables. TB knowledge was predicted by rural residence (coefficient = -6.27, 95% CI: -11.7 to -0.8), and age ≥45 years (coefficient = 7.45, 95% CI: 0.3-14.6). HIV knowledge was only predicted by higher education (coefficient = 0.94, 95%CI: 0.3-1.6). Focus group participants mentioned various beliefs in the aetiology of TB including sharing cups, alcohol consumption, smoking, air pollution, and HIV. Some respondents believed that TB was not curable. CONCLUSION: TB knowledge is low and many misconceptions about TB exist: these should be targeted through health education programs. Both TB and HIV-infection knowledge gaps could be better addressed through an integrated health education program on both infections, whereby TB program managers include HIV information and vice versa.
