Contact screening and latent TB infection treatment in Singapore correctional facilities.

SETTING: Singapore, a city-state with a tuberculosis (TB) incidence rate of 47 per 100000 population in 2000. OBJECTIVES: 1) To report our experience with contact investigation and latent TB infection (LTBI) treatment in high-risk contacts with unknown human immunodeficiency virus (HIV) status in correctional facilities (CFs) (prisons/drug rehabilitation centres); and 2) to compare the yield of contact screening in this setting with that in the community (household/family) setting. METHODS: The tuberculin skin test (TST) readings of 704 CF contacts screened from 1999 to 2001 were compared with those of 2729 household/family contacts who underwent screening in 2000. RESULTS: Respectively eight (1.1%) and 20 (0.7%) active TB cases were detected among the CF and community contacts. A significantly higher proportion of CF contacts had first (non-conversion) TST readings > or =15 mm (39% vs. 22%, OR 2.3; 95%CI 1.9-2.7; P < 0.001), and 10-14 mm (26% vs. 18%, OR 1.6; 95%CI 1.3-2.0; P < 0.001) and TST conversion (43% vs. 20%, OR 2.9; 95%CI 1.7-4.9; P < 0.001). LTBI treatment was started in 65% of the CF contacts screened; 87% completed treatment. CONCLUSION: We found a high LTBI rate among CF contacts, presenting an opportunity for intervention.     

Defaulting from anti-tuberculosis treatment in a teaching hospital in Rio de Janeiro, Brazil.

SETTING: Few studies have investigated factors associated with defaulting from anti-tuberculosis (TB) therapy in hospital settings. OBJECTIVE: To identify the factors associated with defaulting from treatment among TB in-patients in Rio de Janeiro city, Brazil. DESIGN: Case-control study. METHODS: All study participants initiated anti-tuberculosis treatment in a teaching hospital. A defaulting case was defined as a person who did not return for anti-tuberculosis medications after 60 days. Cases and controls were interviewed by a trained health care worker using a standardized form. RESULTS: From 1 January to 31 December 1997, 228 TB cases were registered. After a review of the medical records, 39 were excluded. Household visits were performed in 189 patients; 46 subjects were identified as cases and 117 as controls. Defaulting from anti-tuberculosis treatment was observed in 66 cases (28.9%) before and in 46 (20.2%) after a home visit. After multivariate analysis, the strongest predictors of defaulting from treatment were: 1) returning card not provided (OR 0.099; 95%CI 0.008-1.2; P = 0.07), 2) not feeling comfortable with a doctor (OR 0.16; 95%CI 0.33-0.015; P = 0.001), and 3) blood pressure not measured (OR 0.072; 95%CI 0.036-0.79; P = 0.024). CONCLUSIONS: In this hospital, the factors associated with defaulting from anti-tuberculosis treatment highlight the necessity for a structured TB Control Program. It is expected that the implementation of such a program, pursuing specific approaches, should enhance completion of anti-tuberculosis treatment and cure.     

Association of educational attainment with HIV risk in African American active injection drug users

This study explored the association between educational attainment and HIV/AIDS risk among African American active injection drug users (IDUs) in Chicago, US. Using snowball sampling techniques, 813 African American active IDUs were recruited for semi-structured interviewing and HIV counseling, testing and partner notification. Logistic regression examined the relationship between level of education attained (three categories: less than high school; equivalent to high school; and greater than high school) and HIV risk behaviors (12 unsafe sex and drug-related practices) and HIV serostatus (positive or negative). Compared with the reference category (less than high school education), those with education equal to high school were less likely to share water, p = 0.044, OR = 0.70 (95%CI: 0.50-0.99). Compared with the reference category, those with education greater than high school were less likely to receive money for sex, p = 0.048, OR = 0.62 (95%CI: 0.38-0.99); share needles with person having HIV or AIDS, p = 0.015, OR = 0.58 (95%CI: 0.37-0.90); and test positive for HIV, p = 0.027, OR = 0.58 (95%CI: 0.36-0.94). The significant associations found between educational attainment and certain HIV risk behaviors and HIV serostatus have implications for tailoring HIV prevention efforts for less educated African American IDUs.     

HTLV-1 infection is frequent among out-patients with pulmonary tuberculosis in northern Lima, Peru.

SETTING: Tuberculosis (TB) and human T-lymphotropic virus 1 (HTLV-1) are frequent in Peru. The prevalence of HTLV-1 among Peruvian TB patients is unknown. OBJECTIVE: To determine the prevalence of HTLV-1, HTLV-2 and the human immunodeficiency virus (HIV) in out-patients with TB and to compare HTLV-1-infected patients with seronegative patients. DESIGN: Cross-sectional study including subjects aged 18-65 years diagnosed with smear-positive pulmonary TB at health centres in northern Lima from November 2004 to August 2005. HTLV and HIV screening was performed using enzyme-linked immunosorbent assay; HTLV-1 and HTLV-2 were confirmed using line immunoassay. RESULTS: There were 311 participants with a median age of 29 years; 173 (56%) were men. HTLV-1 prevalence was 5.8% (18/311, 95%CI 3.2-8.4) and HIV prevalence was 1.3% (4/304, 95%CI 0.4-3.3). HTLV-2 was not diagnosed. In comparison with HIV- and HTLV-seronegative patients, HTLV-1-infected subjects were older (median age 44 vs. 28, P < 0.001) and were more likely to have been born in the southern Andes (OR 4.4, 95%CI 1.6-11.9). They were also more likely to report a history of TB deaths in the family (OR 5.4, 95%CI 1.7-16.8) and had more sputum smear results graded as 3+ (OR 4.1, 95%CI 1.5-11.2). CONCLUSION: HTLV-1 screening among Peruvian TB patients is important. Because 3+ sputum smears are frequent and mortality is high among relatives, families of HTLV-1/TB-positive cases merit special attention.     

The relationship between HAART use and sexual activity among HIV-positive women of reproductive age in Brazil, South Africa, and Uganda

The purpose of this study was to determine whether current HAART use is associated with recent sexual intercourse among HIV-infected women (18-49 years) from Brazil, South Africa and Uganda. We conducted an analysis of survey data from a cross-sectional study, which enrolled 179 HIV-infected women receiving regular care from the Mbarara Hospital HIV Clinic in Uganda (n=85); the Perinatal HIV Research Unit in Soweto, South Africa (n=50); and the IPEC-Fiocruz cohort in Rio de Janeiro, Brazil (n=44). The primary outcome was sexual intercourse in the previous month. Secondary outcomes were protected sex and contraceptive use. We found that overall, 46% reported recent sexual intercourse. After adjusting for covariates, recent sexual intercourse was not associated with HAART use (AOR: 0.76; 95%CI: 0.34-1.72); however, it was significantly associated with being currently married, wanting to have more children and having higher HAART optimism. Among women reporting recent sexual intercourse (n=83), HAART users were significantly more likely to practice protected sex (crude OR: 3.64; 95%CI: 1.41-9.38) and non-significantly more likely to use contraceptive methods (crude OR: 2.15; 95%CI: 0.77-5.99). In summary, self-reported recent sexual intercourse is not more likely among women on HAART. Moreover, sexually active HAART users may be more likely to practice protected sex and use contraceptives.     

Prevalence of pulmonary tuberculosis among respiratory symptomatic subjects in an out-patient primary health unit.

SETTING: Out-patient primary health unit (OPHU) in Rio de Janeiro City, Brazil. OBJECTIVE: To evaluate the impact on the detection of tuberculosis (TB) cases of reducing the time of respiratory symptoms from 'cough > or = 3 weeks' to 'cough > or = 1 week' as a criteria for TB case finding among individuals visiting an OPHU for any other reason. DESIGN: Cross-sectional study. RESULTS: During the period of the study, 10.7% (765/ 7174) of subjects reported cough > or = 1 week. Among 542 subjects enrolled in the study with cough > or = 1 week, 15 (2.7%) cases were diagnosed with pulmonary tuberculosis (PTB, 2767/100000). The probability of detecting TB in the OPHU setting among subjects seeking care for respiratory symptoms was significantly higher than among those presenting to the OPHU for other reasons (OR 31.5, 95% CI 4.1-241.9; P < 0.0001). The probability of identifying TB among patients seeking care due to respiratory symptoms was not influenced by the duration of cough (P = 0.7). CONCLUSION: These findings suggest that the screening criteria for TB case finding of cough for less than the usual 3 weeks among patients who attend a health facility due to respiratory symptoms in settings with a high prevalence of TB may significantly improve the proportion of TB cases diagnosed.     

结核病与艾滋病低流行地区MTB/HIV双重感染患者发现模式的效果评价

目的 回顾性分析上海市近10年在结核病患者与HIV/AIDS人群中对HIV抗体和活动性结核病双向筛查的数据,评价MTB/HIV双重感染患者发现模式的效果,为进一步完善相关政策提供依据。 方法 通过《中国结核病信息管理系统》收集2012—2020年结核病患者(68155例)HIV抗体检测结果及结核病诊断、治疗相关资料;通过《结核菌/艾滋病病毒双重感染防治管理工作年度报表》收集2012—2020年HIV/AIDS人群接受结核病相关检查情况。采用线性回归模型评价筛查阳性率随年度的变化趋势,并计算年度变化百分比(APC)和需筛查人数(NNS),评价筛查效果;采用单因素方差分析和多因素logistic回归分析评价2012—2019年上海市长宁区、浦东新区10769例肺结核患者中HIV阳性的影响因素。 结果 2012—2020年上海市累积发现MTB/HIV双重感染患者308例,其中新确诊HIV感染者64例,占全部MTB/HIV双重感染患者的20.78%。2012—2020年间,结核病患者中HIV抗体检测阳性率由2.42%(32/1322)下降到0.50%(20/3995),总体呈下降趋势(APC=-16.64,t=-7.007,P<0.001);HIV/AIDS人群中活动性结核病确诊率由1.02%(50/4912)下降到0.21%(25/11878),同样呈下降趋势(APC=-14.27,t=-4.038,P=0.005)。多因素logistic回归分析显示,男性[OR(95%CI)=5.386(2.306~12.581)],年龄36~75岁[36~45、46~55、56~65、66~75岁OR(95%CI)值分别为26.243(3.230~213.244)、32.736(3.993~268.358)、20.309(2.482~166.144)、13.461(1.692~107.059)],在结核病治疗过程中死亡[OR(95%CI)=14.875(3.192~69.312)],并发肺外结核[OR(95%CI)=3.451(1.607~7.409)]是MTB/HIV双重感染的危险因素。 结论 上海市目前采取的 MTB/HIV双重感染患者发现模式取得了较好的效果,结核病患者的HIV阳性率和HIV/AIDS人群的活动性结核病确诊率均迅速下降。男性、年龄36~75岁、在治疗过程中死亡、并发肺外结核是MTB/HIV双重感染的危险因素。     

Physician adherence to guidelines for tuberculosis and HIV care in Rio de Janeiro,Brazil

BackgroundTuberculosis is the most common opportunistic infection among HIV-infected patients in Brazil. Brazil's national policy for HIV care recommends screening for latent tuberculosis (TB) and implementing isoniazid preventive therapy (IPT).ObjectivesWe compared physician adherence to TB screening and other prevention and care policies among HIV primary care clinics in Rio de Janeiro City.MethodsData on performance of CD4 counts, viral load testing, tuberculin skin testing (TST) and IPT were abstracted from patient charts at 29 HIV clinics in Rio de Janeiro as part of the TB/HIV in Rio (THRio) study. Data on use of pneumocystis jiroveci pneumonia (PCP) prophylaxis were also abstracted from a convenience sample of 150 patient charts at 10 HIV clinics. Comparisons were made between rates of adherence to TB guidelines and other HIV care guidelines.ResultsAmong the subset of 150 patients with confirmed HIV infection in 2003, 96% had at least one reported CD4 counts result; 93% had at least one viral load result reported; and, PCP prophylaxis was prescribed for 97% of patients with CD4 counts < 200 cells/mm3 or when clinically indicated. In contrast, 67 patients (45%) had a TST performed (all eligible); and only 11% (17) of eligible patients started IPT. Among 12,027 THRio cohort participants between 2003 and 2005, the mean number of CD4 counts and viral load counts was 2.5 and 1.9, respectively, per patient per year. In contrast, 49% of 8,703 eligible patients in THRio had a TST ever performed and only 53% of eligible patients started IPT.ConclusionPhysicians are substantially more compliant with HIV monitoring and PCP prophylaxis than with TB prophylaxis guidelines. Efforts to improve TB control in HIV patients are badly needed.     

Improvements in treatment success rates with directly observed therapy in Rio de Janeiro City.

SETTING: Rio de Janeiro City, Brazil. OBJECTIVE: To evaluate the effect of directly observed therapy (DOT) on treatment success, by comparing the treatment success rates between patients treated under DOT with those who received self-administered therapy (SAT). DESIGN: A longitudinal study in a cohort of tuberculosis (TB) patients. Of 9929 new pulmonary TB cases, 1190 (12%) were treated under DOT and 8739 (88%) under SAT. All patients received a three-drug regimen consisting of rifampicin (RMP), isoniazid (INH) and pyrazinamide for 2 months followed by 4 months of RMP and INH. RESULTS: Patients under DOT were more likely to convert to sputum-negative at the end of the second month than those treated under SAT (86.3% vs. 61.9%, P < 0.001). DOT alone was significantly associated with successful treatment (OR 1.6, 95%CI 1.37-1.86, P < 0.001), even when controlled by sex, age and positive smear or culture at enrollment (OR 1.56, 95%CI 1.33-1.82, P < 0.001). CONCLUSION: This pilot DOTS implementation phase showed that DOT is highly effective and feasible in a large urban centre of a developing country.     

Tuberculosis treatment default among Brazilian children.

OBJECTIVES: To study the prevalence and time of tuberculosis (TB) treatment default among children and to compare defaulters with those who completed treatment. METHODS: Retrospective cohort study at the Hospital Municipal Jesus, Rio de Janeiro, Brazil, among TB patients aged <15 years followed from 1998 to 2002. The group that completed treatment was compared with those that defaulted. RESULTS: The records of 248 patients were studied. The default rate was 24.2% and was more frequent in the first 2 months of treatment (43.3%) and among those aged <1 year (42.4%). The following variables were associated with default: previous default (relative risk [RR] 1.99, 95%CI 1.12-3.54, P = 0.035), father not living with the child (RR 1.85, 95%CI 1.06-3.21, P = 0.030) and father using illicit drugs (RR 2.93, 95%CI 1.44-5.97, P = 0.002). CONCLUSIONS: Health professionals responsible for treating children with TB should pay special attention to children aged <1 year, those with a history of previous default, and those whose father is absent or an illicit drug user.     

INH preventive therapy among adult HIV-infected patients in Thailand.

SETTING: Two HIV/AIDS clinics in Bangkok. OBJECTIVE: Although isoniazid (INH) preventive therapy (IPT) can reduce the risk of active TB among HIV-infected individuals, preventive therapy is rarely used in developing countries. The WHO recommends INH prophylaxis for tuberculin skin test (TST) positive HIV positives or for all HIV positives in countries with a high prevalence of latent TB if TST is unfeasible. It is not known whether IPT without TST will affect adherence. DESIGN: Prior to receiving IPT, 914 HIV-infected patients in Bangkok were randomized to TST or not. Adherence, measured by self-report and pill counts, and proportion completing therapy were evaluated. RESULTS: Adherence was 84.5% and 79.7%, by self-report, and 81.8% and 73.9% by pill count, respectively, in PPD-positive and non-TST-screened subjects (adjusted OR 1.44, 95%CI 0.79-2.64 and 1.53, 95%CI 0.45-5.26). The drop-out rate before treatment was 6.3% in the TST-screened and 1.7% in the non-TST screened subjects (OR 3.93, 95%CI 1.18-16.04). CONCLUSION: TST screening was not a predictor of adherence to IPT once therapy began, but it was associated with a higher drop-out rate prior to therapy. Acceptable levels of adherence were observed with both regimens.     

TB prevention in HIV clinics in New York City.

SETTING: Ten hospital-based human immunodeficiency virus (HIV) clinics in New York City. OBJECTIVE: To evaluate tuberculosis (TB) prevention in HIV clinics based on the prevalence and incidence of TB and the efficacy of preventive therapy with isoniazid (INH). DESIGN: The medical records of 2393 HIV-infected patients with a first clinic visit in 1995 were reviewed retrospectively. Deaths and TB cases through December 1997 were ascertained through a match with the TB and AIDS registries. RESULTS: At first visit, 92 patients (4%) had a history of TB, 98 (4%) were being treated for TB, and six (<1%) were diagnosed with TB. During follow-up, 23 cases were diagnosed, an incidence of 0.53 per 100 person-years (py) (95%CI 0.34-0.77). Among 439 tuberculin skin test (TST) positive patients, the incidence of TB/100 py was 1.63 (95%CI 0.27-5.02) in patients with no INH, 1.28 (95%CI 0.40-2.98) in patients with <12 months of INH, and 1.06 (95%CI 0.38-2.28) in patients with 12 months of INH. The incidence/100 py was 0.0 (95%CI 0.0-0.78) in TST-negative patients and 0.37 (95%CI 0.09-0.95) in anergic patients. The relative risk of TB was 0.65 (95%CI 0.14-4.56) in TST-positive patients with 12 months of INH (vs. none). CONCLUSIONS: The benefits of TB prevention efforts in these HIV clinics from 1995 to 1997 were limited because most TB occurred before the first clinic visit. Methods for reaching HIV-infected patients earlier should be identified.     

Predictors of development and outcome in patients with acute respiratory distress syndrome due to tuberculosis.

OBJECTIVE: To study the predictors of development and determinants of outcome in patients with acute respiratory distress syndrome (ARDS) due to tuberculosis (TB). METHODS: Retrospective case-control study of demographic, clinical and laboratory data of hospitalised adult patients with active TB. RESULTS: Of 2733 TB patients treated during 1980-2003, 29 (1.06%; 1.21 patients/year; mean age 31.6 +/- 10.9 years; 16 males) developed ARDS (cases). Seven had pulmonary TB and 22 had miliary TB (MTB); 298 (mean age 32.0 +/- 14.2 years; 110 males) who did not develop ARDS constituted controls. Presence of MTB (OR 4.6, 95%CI 1.2-17.8; P = 0.02), duration of illness beyond 30 days at presentation (OR 177.9, 95%CI 39-811.7; P < 0.001), absolute lymphocyte count < 1625/ mm3 (OR 4.5, 95%CI 1.1-19.3; P = 0.04) and serum ALT > 100 IU (OR 15.7, 95%CI 3.0-81.1, P < 0.001) were independent predictors of ARDS development. Twelve cases died (41.4%). Patients with APACHE II score >18; those with APACHE II score <18 in the presence of hyponatraemia and PaO2/FIO2 ratio <108.5 were likely to die. CONCLUSIONS: In patients with TB, prolonged illness, MTB, absolute lymphocytopaenia and elevated ALT are independently associated with ARDS development. APACHE II score, serum sodium and PaO2/FIO2 ratio are determinants of outcome.     

Prevalence of M. tuberculosis infection and tuberculosis disease among HIV-infected people in Spain.

OBJECTIVE: To study the prevalence of Mycobacterium tuberculosis infection (MTBI) and past/current tuberculosis (TB) among human immunodeficiency virus (HIV) infected persons in Spain. DESIGN: Longitudinal study conducted between 2000 and 2003 at 10 HIV hospital-based clinics. Data were drawn from clinical records. Associations were measured using odds ratios (ORs) and their 95% confidence intervals (95%CI). RESULTS: Of the 1242 persons who met the eligibility criteria, most were male (75%), aged <40 years (75%) and unemployed (40%). HIV infection occurred through intravenous drug use (53%), heterosexual sex (29%) and sex between men (16%). In the initial evaluation, 315 subjects had evidence of MTBI: 84 (6.8%) had a history of TB, 23 (1.8%) current TB and 208 (16.8%) latent tuberculosis infection (LTBI). MTBI was associated with male sex, age 30-49 years, contact with a TB case, homelessness, poor education, and negatively with CD4 <100 cells/mm(3). Among subjects with MTBI, past/current TB was associated with retirement/disability (OR 6, 95%CI 1.6-22.5), CD4 <200 cells/mm(3) (OR 9.7, 95%CI 3.8-24.6), viral load >55,000 copies (OR 5.3, 95%CI 1.4-20.0), and negatively, with skilled work (OR 0.4, 95%CI 0.1-1.0) or administrative/managerial/professional work (OR 0.05, 95%CI 0.01-0.4). CONCLUSION: Social context has an impact on the effectiveness of HIV and TB control programmes even in industrialised countries with free access to health care.     

Tuberculosis risk among staff of a large public hospital in Kenya

SETTING: In sub-Saharan Africa, high rates of tuberculosis (TB) and human immunodeficiency virus (HIV) infection pose a serious threat for occupationally acquired TB among health care workers. OBJECTIVE: To identify factors associated with TB disease among staff of an 1800-bed hospital in Kenya. DESIGN: We calculated TB incidence among staff and conducted a case-control study where cases (n = 65) were staff diagnosed with TB and controls (n = 316) were randomly selected staff without recent TB. RESULTS: The annual incidence of TB from 2001 to 2005 ranged from 645 to 1115 per 100000 population. Factors associated with TB disease were additional daily hours spent in rooms with patients (adjusted odds ratio [aOR] 1.3, 95%CI 1.2-1.5), working in areas where TB patients received care (aOR 2.1, 95%CI 1.1-4.2), HIV infection (aOR 29.1, 95%CI 5.1-167) and living in a slum (aOR 4.7, 95%CI 1.8-12.5) or hospital-provided low-income housing (aOR 2.6, 95%CI 1.2-5.6). CONCLUSION: Hospital exposures were associated with TB disease among staff at this hospital regardless of their job designation, even after controlling for living conditions, suggesting transmission from patients. Health care facilities should improve infection control practices, provide quality occupational health services and encourage staff testing for HIV infection to address the TB burden in hospital staff.     

Chest radiograph screening for tuberculosis in a Hong Kong prison.

SETTING: Long-stay prisoners are not regularly screened for TB in Hong Kong. OBJECTIVE: To evaluate tuberculosis (TB) screening in prison. METHOD: All prisoners in a maximum security prison as of 31 October 2001 were screened by chest radiograph (CXR), except for those being followed up for TB or examined by CXR in the last 6 months. RESULTS: A total of 814 male prisoners aged 34.6 +/- 9.6 (mean +/- SD) years were successfully screened. Of 53 cases (6.51%) with radiographic abnormalities, 10 active TB cases (8 culture-negative, 2 culture-positive) were diagnosed, giving an overall yield of 1.23% (95%CI 0.59-2.26). There was no statistical difference in age, ethnicity, place of birth or residency status between those with and those without TB (all P > 0.05). Incarceration > or = 2 years, being in current prison > or = 2 years and not having CXR in last 2 years were associated with TB in univariate analysis (all P < 0.05), but only the last remained an independent predictor in multiple logistic regression (OR 16.8, 95%CI 2.1-132.9, P = 0.008). In that group, the yield was 3.1% (95%CI 1.42-5.89). No further cases were detected in the subsequent 2 years. CONCLUSION: CXR screening of long-stay prisoners gave a high yield in this study.     

Tolerability of anti-tuberculosis treatment and HIV serostatus.

SETTING: Tuberculosis (TB) is frequent in human immunodeficiency virus (HIV) infected patients, but its treatment is hampered by adverse events and paradoxical reactions. OBJECTIVE: To examine the impact of HIV infection and other factors on the risk and spectrum of adverse events related to anti-tuberculosis treatment in a prospective cohort study conducted between January 2003 and August 2004. RESULTS: Of 105 patients treated for TB, 30 were HIV-infected. The overall incidence of adverse events was 122.5 +/- 18.5 per 100 patient-years (py) and the incidence of severe adverse events was 45.2 +/- 11.3/100 py. Age >50 years (OR 2.2, 95%CI 1.01-4.8, P = 0.046) and HIV infection (OR 3.9, 95%CI 2.1-7.5, P < 0.001) were independently associated with a higher risk of adverse events. Hepatitis (30.5/100 py) and neuropathy (28.6/100 py) were the most frequent adverse events. Hepatitis C virus infection was associated with hepatitis (OR 4.2, 95%CI 1.2-15.0, P = 0.028) and neuropathy with HIV infection (OR 3.8, 95%CI 1.1-13.7, P = 0.040). CONCLUSION: Adverse reactions to anti-tuberculosis drugs are frequent. HIV infection and age >50 years are factors associated with such reactions, while hepatitis C virus infection is a risk factor for hepatitis.     

Current status of treatment completion and fatality among tuberculosis patients in Spain.

OBJECTIVES: To determine treatment completion among patients with tuberculosis (TB), and to analyse factors associated with treatment default and fatality. METHODS: A prospective cohort study of patients who began treatment between 1 June 1999 and 31 May 2000 in areas where members of the SEPAR Tuberculosis and Respiratory Infections Group work. Factors associated with treatment default and fatality were studied using logistic regression, calculating odds ratios (OR) and their 95% confidence intervals (95%CI). RESULTS: The study involved 142 physicians from 76 different hospitals who provided information on 1515 cases. Eighty-two per cent of the patients completed treatment correctly, 14% defaulted, 5% died, 0.5% failed, and 8.7% interrupted treatment due to transfer or other reasons. The variables associated with default were intravenous drug use (IVDU) (OR 6.00, 95%CI 2.59-13.89) and immigration (OR 8.57, 95%CI 3.78-19.45); sex, age, homelessness, incarceration, directly observed treatment (DOT) or hospitalisation were not associated with default. Variables found to be predictive of fatality were alcoholism (OR 6.38, 95%CI 2.09-19.48), human immunodeficiency virus (HIV) infection (OR 7.08, 95%CI 2.08-29.15) and age >64 years (OR 10, 95%CI 2.9-34.07), whereas sex, IVDU, homelessness, DOT and hospitalisation were not. CONCLUSIONS: In industrialised countries, IVDU patients and immigrants should be targeted for DOT, while to reduce fatality rates stricter monitoring is required for patients who are alcoholic, HIV-infected, or aged >64 years.     

Acceptance of HIV testing among women attending antenatal care in south-western Uganda: risk factors and reasons for test refusal

A problem commonly encountered in programs for prevention of mother-to-child-transmission (PMTCT) of HIV in sub-Saharan Africa is low rates of HIV test acceptance among pregnant women. In this study, we examined risk factors and reasons for HIV test refusal among 432 women attending three antenatal care clinics offering PMTCT in urban and semi-urban parts of the Mbarara district, Uganda. Structured interviews were performed following pre-test counselling. Three-hundred-eighty women were included in the study, 323 (85%) of whom accepted HIV testing. In multivariate analysis, testing site (Site A: OR = 1.0; Site B: OR = 3.08; 95%CI: 1.12-8.46; Site C: OR = 5.93; 95%CI: 2.94-11.98), age between 30 and 34 years (<20 years: OR = 1.0; 20-24 years: OR = 1.81; 95%CI: 0.58-5.67; 25-29 years: OR = 2.15; 95%CI: 0.66-6.97; 30-34 years: OR = 3.88; 95%CI: 1.21-13.41), mistrust in reliability of the HIV test (OR = 20.60; 95%CI: 3.24-131.0) and not having been tested for HIV previously (OR = 2.15; 95%CI: 1.02-4.54) were associated with test refusal. Testing sites operating for longer durations had higher rates of acceptance. The most common reasons claimed for test refusal were: lack of access to antiretroviral therapy (ART) for HIV-infected women (88%; n=57), a need to discuss with partner before decision (82%; n=57) and fear of partner's reaction (54%; n=57). Comparison with previous periods showed that the acceptance rate increased with the duration of the program. Our study identified risk factors for HIV test refusal among pregnant women in Uganda and common reasons for not accepting testing. These findings may suggest modifications and improvements in the performance of HIV testing in this and similar populations.     

Drug-resistant tuberculosis and HIV in Ukraine: a threatening convergence of two epidemics?

OBJECTIVE: To investigate anti-tuberculosis (TB) drug resistance rates in Donetsk Oblast, Ukraine, and to explore the association between the epidemics of human immunodeficiency virus (HIV) and multidrug-resistant TB (MDR-TB). METHODS: All consecutive newly diagnosed and previously treated patients with sputum smear-positive TB presenting to all TB units in Donetsk Oblast over 12 months were invited to take part in the study. A total of 1293 and 203 patients with TB were tested for HIV and MDR-TB in the civilian and penitentiary sectors, respectively. RESULTS: Of those enrolled for the study, 307 were HIV-positive, 379 had MDR-TB, and 97 had MDR-TB and HIV co-infection. MDR-TB rates in the civilian sector were respectively 15.5% (95%CI 13.1-17.8) and 41.5% (95%CI 36.4-46.5) in newly diagnosed and previously treated TB patients. Among prisoners, MDR-TB rates were 21.8% (95%CI 12.4-31.2) in new cases and 52.8% (95%CI 43.9-61.7) in previously treated TB cases. HIV status was significantly associated with MDR-TB (OR 1.7, 95%CI 1.3-2.3). CONCLUSIONS: High MDR-TB rates and a positive association between MDR-TB and HIV epidemics were found in Donetsk Oblast. Urgent measures to improve HIV prevention, control of drug-resistant TB and collaboration between HIV and TB control activities need to be implemented without further delay.
