OBJECTIVES: To assess the feasibility and effectiveness of voluntary counselling, HIV testing and adjunctive cotrimoxazole in reducing mortality in a cohort of tuberculosis (TB) patients registered under routine programme conditions in a rural district of Malawi. DESIGN: 'Before' and 'after' cohort study using historical controls. METHODS: Between 1 July 1999 and 30 June 2000 all TB patients were started on standardized anti-TB treatment, and offered voluntary counselling and HIV testing (VCT). Those found to be HIV-positive were offered cotrimoxazole at a dose of 480 mg twice daily, provided there were no contraindications. Side-effects were monitored clinically. End-of-treatment outcomes in this cohort (intervention group) were compared with a cohort registered between 1 July 1998 and 30 June 1999 in whom VCT and cotrimoxazole was not offered (control group). FINDINGS: A total of 1986 patients was registered in the study: 1061 in the intervention group and 925 in the control cohort. In the intervention group, 1019 (96%) patients were counselled pre-test, 964 (91%) underwent HIV testing and 938 (88%) were counselled post-test. The overall HIV-seroprevalence rate was 77%. A total of 693 patients were given cotrimoxazole of whom 14 (2%) manifested minor dermatological reactions. The adjusted relative risk of death in the intervention group compared with the control group was 0.81 (P < 0.001). The number needed to treat with VCT and adjunctive cotrimoxazole to prevent one death during anti-TB treatment was 12.5. INTERPRETATION: This study shows that VCT and adjunctive cotrimoxazole is feasible, safe and reduces mortality rates in TB patients under routine programme conditions.  相似文献

OBJECTIVES: A study was conducted in new patients registered with tuberculosis (TB) in a rural district of Malawi in order to 1) verify the acceptability of voluntary counselling and testing for human immunodeficiency virus (HIV) infection; 2) describe sexual behaviour and condom use; and 3) identify socio-demographic and behavioural risk factors associated with 'no condom use'. DESIGN: Cross-sectional study. METHODS: Consecutive patients diagnosed with TB between January and December 2000 were offered voluntary counselling and HIV testing (VCT) and were subsequently interviewed. RESULTS: There were 1,049 new TB patients enrolled in the study. Of these, 1,007 (96%) were pre-test counselled, 955 (91%) underwent HIV testing and 912 (87%) were post-test counselled; 43 (4%) patients refused HIV testing. The overall HIV infection rate was 77%. Of all HIV-positive TB patients, 691 (94%) were put on cotrimoxazole. There were 479 (49%) TB patients who reported sexual encounters, of whom only 6% always used condoms. Unprotected sex was associated with having TB symptoms for over 1 month, having had less than 8 years of school education, being single, divorced or widowed or having sex with the same partner. CONCLUSIONS: Offering VCT to TB patients in this setting has a high acceptance rate and provides an opportunity to strengthen and integrate TB and HIV programmes.  相似文献

SETTING: Thyolo, rural southern Malawi. OBJECTIVES: To determine 1) the proportion who continue with cotrimoxazole prophylaxis for the prevention of opportunistic infections, and 2) the reasons for continuing or stopping prophylaxis, in human immunodeficiency virus (HIV) infected individuals with tuberculosis (TB) who complete anti-tuberculosis treatment. DESIGN: A cross-sectional study. METHODS: A questionnaire study of all HIV-infected TB patients who had been registered over a 3-month period to receive anti-tuberculosis treatment and cotrimoxazole prophylaxis and who had completed antituberculosis treatment 3-6 months earlier. RESULTS: Of 82 HIV-infected individuals who were alive at the time of interview, 76 (93%) were continuing with cotrimoxazole and wished to do so indefinitely. The most common reason for continuing the drug was to prevent illness associated with HIV, while the most common reason for stopping was long distances to the health facility. Ninety-six percent of patients received cotrimoxazole free of charge from a health centre. Of those who wished to continue indefinitely, the majority (63%) could not afford to pay for the drug. CONCLUSIONS: In a rural setting, the great majority of HIV-infected individuals continued with cotrimoxazole after completing anti-tuberculosis treatment. Making the drug available and providing it free of charge is essential if it is to remain accessible for longer term prevention.  相似文献

SETTING: Public sector facilities in Malawi providing antiretroviral therapy (ART) to human immunodeficiency virus (HIV) positive patients, including those with tuberculosis (TB). OBJECTIVES: To compare 6-month and 12-month cohort treatment outcomes of HIV-positive TB patients and HIV-positive non-TB patients treated with ART. DESIGN: Retrospective data collection using ART patient master cards and ART patient registers. RESULTS: Between July and September 2005, 7905 patients started ART, 6967 with a non-TB diagnosis and 938 with a diagnosis of active TB. 6-month cohort outcomes of non-TB and TB patients censored on 31 March 2006 showed significantly more TB patients alive and on ART (77%) compared with non-TB patients (71%) (P < 0.001). Between January and March 2005, 4580 patients started ART, 4179 with a non-TB diagnosis and 401 with a diagnosis of active TB. 12-month cohort outcomes of non-TB and TB patients censored on 31 March 2006 showed significantly more TB patients alive and on ART (74%) compared with non-TB patients (66%) (P < 0.001). Other outcomes of default and transfer out were also significantly less frequent in TB compared with non-TB patients. CONCLUSION: HIV-positive TB patients on ART in Malawi have generally good treatment outcomes, and more patients need to access this HIV treatment.  相似文献

SETTING: Thyolo district, Malawi. OBJECTIVES: To report on 1) case fatality among human immunodeficiency virus (HIV) positive tuberculosis (TB) patients while on anti-tuberculosis treatment and 2) whether antiretroviral treatment (ART) initiated during the continuation phase of TB treatment reduces case fatality. DESIGN: Retrospective cohort analysis. METHODS: Comparative analysis of treatment outcomes for TB patients registered between January and December 2004. RESULTS: Of 983 newly registered TB patients receiving diagnostic HIV testing, 658 (67%) were HIV-positive. A total of 132 (20%) patients died during the 8-month course of anti-tuberculosis treatment, of whom 82 (62%) died within the first 2 months of treatment when ART was not provided (cumulative incidence 3.0, 95%CI 2.5-3.6 per 100 person-years). A total of 576 TB patients started the continuation phase of anti-tuberculosis treatment, 180 (31%) of whom were started on ART. The case-fatality rate per 100 person-years was not significantly different for patients on ART (1.0, 95%CI 0.6-1.7) and those without ART (1.2, 95%CI 0.9-1.7, adjusted hazard ratio 0.86, 95%CI 0.4-1.6, P = 0.6) CONCLUSIONS: ART provided in the continuation phase of TB treatment does not have a significant impact on reducing case fatality. Reasons for this and possible measures to reduce high case fatality in the initial phase of TB treatment are discussed.  相似文献

SETTING: Lilongwe Central Hospital, Malawi. OBJECTIVES: To investigate 1) treatment outcome of a cohort of smear-negative pulmonary TB (snPTB) patients in an area of high human immunodeficiency virus (HIV) seroprevalence, and 2) whether poor treatment outcomes are due to non-TB patients being mistakenly treated for TB due to lack of diagnostic facilities. DESIGN: Patients about to be registered for snPTB treatment by the National TB Programme underwent further assessment including TB culture, bronchoscopy and bronchoalveolar lavage. All patients were followed up for 8 months. Standard TB control treatment outcomes were recorded. RESULTS: Of 352 snPTB patients assessed, 137 patients had bacteriologically confirmed TB, 136 had possible TB, and 79 had other non-TB diagnoses. The HIV seroprevalence rate was 89%. Outcomes were known for 325 (92%) patients: 129 (40%) died within 8 months. Death rates on TB treatment were 31% for bacteriologically confirmed TB patients and 35% for patients with possible TB but no bacteriological diagnosis. The death rate among patients with non-TB diagnoses was 53%. HIV infection significantly increased the risk of death (OR 3.9; P = 0.01). CONCLUSION: SnPTB is strongly associated with HIV infection in Malawi, where patients treated for snPTB have a poor prognosis. The high mortality is not fully explained by non-TB patients being mistakenly treated for TB.  相似文献

BACKGROUND: Adults with dual tuberculosis (TB) and HIV infection have a poor outcome. Studies in West Africa suggest that cotrimoxazole prophylaxis may reduce this mortality. OBJECTIVE: To evaluate the effectiveness of cotrimoxazole in reducing mortality in adults with active TB, irrespective of HIV status, in a high prevalence setting. DESIGN: Cohort study using historical controls. METHODS: Adults treated for TB between 1998 and 2000 were traced and vital status at 6 months ascertained (2004: control group). All adults starting treatment for TB between June 2001 and June 2002 were offered cotrimoxazole prophylaxis 960 mg once daily for 6 months during TB treatment irrespective of HIV status (1321: intervention group). Mortality, adverse reactions and adherence were compared between intervention and control groups. RESULTS: HIV seroprevalence in patients with TB at the start of the intervention was estimated to be 78%. Mortality at 6 months was 29% lower in the group given cotrimoxazole than in the control group. The number needed to treat to prevent one death during the period of TB treatment was 24. The benefit was seen across all types of TB but was only evident in new patients; patients being retreated had similar outcomes in both groups. Adverse events were infrequent and minor, with only two participants having treatment stopped for this reason. CONCLUSION: Cotrimoxazole prophylaxis for all adults with TB, irrespective of HIV status, in an area of high HIV seroprevalence may be a feasible, safe and effective way to reduce mortality for the duration of treatment.  相似文献

OBJECTIVE: To verify compliance with cotrimoxazole prophylaxis in human immunodeficiency virus (HIV) infected tuberculosis (TB) patients during the continuation phase of anti-tuberculosis treatment, and to assess the sensitivity, specificity and positive predictive values of verbal verification and pill counts as methods of checking compliance. DESIGN: Cross-sectional study. METHODS: Cotrimoxazole compliance was assessed in a cohort of TB patients who were attending four TB follow-up centres during the continuation phase of anti-TB treatment between months 4 and 6. Verbal verification of drug intake, physical verification of pill count balance, and urine trimethoprim detection by gas chromatography and mass spectrometry were used for assessing compliance. RESULTS: Using urine trimethoprim detection as the gold standard for compliance, trimethoprim was detected in 82 (94%) of 87 patients in the cohort. Verbal verification of cotrimoxazole intake and objective pill count balances showed high sensitivity and positive predictive values compared with the gold standard of urine trimethoprim detection. CONCLUSIONS: In a rural district in Malawi, compliance with cotrimoxazole as an adjunct to anti-tuberculosis treatment in HIV-infected TB patients was good, and can be assessed simply and practically by verbal verification and pill counts.  相似文献

OBJECTIVES: Voluntary counseling and testing (VCT) for the human immunodeficiency virus (HIV) is recommended for persons treated for tuberculosis (TB). Opportunities to diagnose HIV may be missed by limiting HIV testing to only persons diagnosed with TB. Among TB suspects in Uganda, we determined HIV prevalence, risk behaviors, and willingness to refer family for VCT. METHODS: Consenting adult patients presenting for evaluation at a referral TB clinic received same-day VCT. TB diagnosis data were abstracted from clinical records. RESULTS: Among 665 eligible patients, 565 (85%) consented to VCT. Among these, 238 (42%) were HIV-positive. Of the HIV-infected patients, 37% had received a non-TB diagnosis. HIV seroprevalence was higher in patients with a non-TB diagnosis (49%) than those diagnosed with TB (39%) (P = 0.02). Fewer than 6% of HIV-infected patients reported always using condoms with sexual partners. The majority of patients (86%) reported being 'very willing' to refer family members for VCT. CONCLUSIONS: Over 35% of HIV-infected cases in our population would have been undetected if HIV testing was limited to cases with diagnosed TB. The high HIV seroprevalence in both TB and non-TB cases merits HIV testing for all patients evaluated at TB clinics. HIV-infected TB suspects reporting high-risk behavior are at risk for HIV transmission, and should receive risk-reduction counseling.  相似文献

The World Health Organization (WHO) has set a target of treating 3 million people with antiretroviral treatment (ART) by 2005. In sub-Saharan Africa, HIV-positive tuberculosis (TB) patients could significantly contribute to this target. ART (stavudine/lamivudine/nevirapine) was initiated in Thyolo district, Malawi, in April 2003, and all HIV-positive TB patients were considered eligible and offered ART. Despite this, only 44 (13%) of 352 TB patients were eventually started on ART by the end of November 2003. Most TB patients leave hospital after 2 weeks to complete the initial phase of anti-tuberculosis treatment (rifampicin-based) in the community, and ART is offered to HIV-positive TB patients after they have started the continuation phase of treatment (isoniazid/ ethambutol). ART is only offered at hospital, while the majority of TB patients take their continuation phase of anti-tuberculosis treatment from health centres. HIV-positive TB patients therefore find it difficult to access ART. In this paper, we discuss a series of options to increase the uptake of ART among HIV-positive TB patients. The main options are: 1) to hospitalise HIV-positive TB patients with a view to starting ART in the continuation phase in hospital; 2) to decentralise ART delivery so ART can be delivered at health centres; 3) to replace nevirapine with efavirenz so ART can be started earlier in the initial phase of anti-tuberculosis treatment. Decentralisation of ART from hospitals to health centres would greatly improve ART access.  相似文献

SETTING: All 43 non-private hospitals in Malawi which in 1999 registered and treated patients with tuberculosis (TB). OBJECTIVE: To determine the proportion of TB patients who transferred from one reporting unit to another and their treatment outcome, and to compare outcome results between the main TB register and the transfer-in register. DESIGN: Retrospective data collection, using the main TB register and transfer-in register, on all patients registered in Malawi in 1999. RESULTS: There were 24,908 patients, of whom 3249 (13%) in total were transfers. Significantly more patients transferred from mission hospitals (23%) compared with central (8%) or district (5%) hospitals (P < 0.001). The date of transfer was recorded for 1406 patients, of whom 1170 (83%) transferred in the first 10 weeks. Respectively 45% and 58% of transfer patients had unknown outcomes in the main TB register and transfer-in register; these rates were significantly lower in smear-positive pulmonary TB (PTB) patients. A total of 1357 patients were entered into transfer-in registers; 694 patients had matched names and/or registration numbers in both registers. Of the matched patients, 373 (54%) had similar treatment outcomes. CONCLUSION: It is common for patients to transfer between treatment units, but the quality of the data for patients who transfer is poor, and needs to be improved.  相似文献

SETTING: Thyolo district, rural Malawi. OBJECTIVES: To compare passive with active case finding among household contacts of smear-positive pulmonary tuberculosis (TB) patients for 1) TB case detection and 2) the proportion of child contacts aged under 6 years who are placed on isoniazid (INH) preventive therapy. DESIGN: Cross-sectional study. METHODS: Passive and active case finding was conducted among household contacts, and the uptake of INH preventive therapy in children was assessed. RESULTS: There were 189 index TB cases and 985 household contacts. Human immunodeficiency virus (HIV) prevalence among index cases was 69%. Prevalence of TB by passive case finding among 524 household contacts was 0.19% (191/100000), which was significantly lower than with active finding among 461 contacts (1.74%, 1735/100000, P = 0.01). Of 126 children in the passive cohort, 22 (17%) received INH, while in the active cohort 25 (22%) of 113 children received the drug. Transport costs associated with chest X-ray (CXR) screening were the major reason for low INH uptake. CONCLUSIONS: Where the majority of TB patients are HIV-positive, active case finding among household contacts yields nine times more TB cases and is an opportunity for reducing TB morbidity and mortality. The need for a CXR is an obstacle to the uptake of INH prophylaxis.  相似文献

Scaling up of counselling and HIV testing (VCT) services requires a system of regular monitoring and evaluation. AVCT monitoring tool was developed through a consultative process and used to assess counselling and HIV testing services in 16 government and mission hospitals in Malawi, which had started expanded HIV-TB activities in July 2003. The essential components of theVCT monitoring tool included assessments of: (i) the hospital VCT personnel, in particular the number of counsellors (full-time and part-time) and those trained in and performing whole blood rapid HIV testing; (ii) the hospital laboratory service, in particular the protocols for HIV testing; (iii) the number, structure and function of dedicated VCT rooms; (iv) registers for patients, clients and donors having HIV tests; and (v) the quality of VCT through structured interviews with HIV-positive patients with TB. The main findings were: 9644 patients and clients were HIV tested between July and September 2003; HIV testing protocols were not standardized and differed between hospitals; there was little in the way of external quality assurance and there were deficiencies in the counselling process. In each hospital, the mean time taken to obtain the data and complete theVCT monitoring tool was 3 h. TheVCT monitoring tool is straightforward to use, and the data collected should help to improve standardization, quality and future planning of VCT services in the country.  相似文献

A cross-sectional study was carried out in all 43 hospitals in Malawi that register and treat tuberculosis (TB) patients to determine whether there is care and treatment for human immunodeficiency virus (HIV) complications in TB patients. Of 1,416 adults with TB, 861 (61%) had HIV complications, 627 (44%) patients had received no ward round, and of 1,142 patients who had been on anti-tuberculosis treatment for more than 7 days, 294 (26%) had not had a clinical review. Of patients with HIV complications, only 139 (16%) were receiving treatment. There is a lack of regular care and treatment for HIV complications in TB patients in Malawi.  相似文献

SETTINGS: Twelve large public hospitals geographically distributed in Thailand. OBJECTIVES: To assess the uptake of diagnostic human immunodeficiency virus (HIV) counselling and testing (DCT), HIV prevalence in tuberculosis (TB) patients and HIV services provided to newly diagnosed HIV-infected TB patients. METHOD: We provided DCT in TB clinics to newly registered TB patients. Post-test counselling was provided at TB clinics for non-HIV-infected patients and at HIV voluntary counselling and testing centres for HIV-infected patients. HIV-infected patients were referred for HIV-related care during TB treatment. RESULTS: From July to October 2006, 8% of 1086 new TB patients were known to be HIV-infected at the time of TB diagnosis. Of 1000 patients with unknown HIV status, 93% were tested: HIV infection was diagnosed in 11%. Including patients with previously diagnosed HIV infection, 17% of all TB patients were HIV-infected. Of 99 newly diagnosed HIV patients, 36% received cotrimoxazole prophylaxis. Of 41 with CD4 < 200 cells/microl, 42% began antiretroviral treatment during TB treatment. CONCLUSION: The acceptance of DCT was high, but the provision of HIV services was disappointingly low. Increased staff capacity building, stronger coordination with the acquired immune-deficiency syndrome programme and better field supervision are needed to achieve universal access to care for HIV-infected TB patients.  相似文献

Objectives To describe the development and operation of integrated tuberculosis (TB) and HIV care at the Martin Preuss Centre, a multipartner organization bringing together governmental and non‐governmental providers of HIV and TB services in Lilongwe, Malawi. Methods We used a case study approach to describe the integrated TB/HIV service and to illustrate successes and challenges faced by service providers. We quantified effective TB and HIV integration using indicators defined by the World Health Organization. Results The custom‐designed building facilitates patient flow and infection control, and other important elements include coordinated leadership; joint staff training and meetings; and data systems prompting coordinated care. Some integrated services have worked well from the outset, such as promoting HIV testing among patients with TB (96% of patients with TB had documented HIV status in 2009). Other aspects of integrated care have been more challenging, for example achieving high uptake of antiretroviral therapy among HIV‐positive TB patients and combining data from paper and electronic systems. Good TB treatment outcomes (>85% cure or completion) have been achieved among both HIV‐positive and HIV‐negative individuals. Conclusions High‐quality integrated services for TB and HIV care can be provided in a resource‐limited setting. Lessons learned may be valuable for service providers in other settings of high HIV and TB prevalence.  相似文献

OBJECTIVE: To assess the efficacy and safety of two different dosages of cotrimoxazole (CTX) in prophylaxis in HIV-positive new smear-positive pulmonary tuberculosis (TB) patients in Blantyre, Malawi. METHOD: Randomized, double-blind trial using 480 and 960 mg of CTX given to new TB patients, who were followed up until the end of the tuberculosis treatment. The primary outcome was survival. The outcome in the two groups was also compared with an unselected cohort of similar patients registered in Zomba, Malawi in 1995 and new smear-positive patients registered in the National Tuberculosis Programme in 1999. The secondary outcome was the occurrence of (opportunistic) events, especially bacterial pneumonia. RESULTS: There were no statistically significant differences in mortality and bacterial pneumonia between the groups receiving the two different dosages. The case fatality rate at the end of the tuberculosis treatment was 15.4% in the 480 mg group and 14.0% in the 960 mg group. This was lower than the case fatality rate in the Zomba cohort (19.2%, P = 0.10) and lower than the case fatality rate in the national programme (21.0%, P < 0.001). CTX was well tolerated. Compliance was fair. CONCLUSIONS: CTX prophylaxis may have a beneficial effect on mortality and morbidity in HIV-infected smear-positive tuberculosis patients in Malawi. The efficacy of both dosages is not significantly different. The intervention is cheap and easy to implement. These results would support implementation of CTX in this patient group until better strategies are available or evidence is convincingly presented to suggest that its benefit is marginal.  相似文献

SETTING: Central Chest Hospital, a 500-bed referral hospital near Bangkok with a large out-patient department. OBJECTIVES: To determine human immunodeficiency virus (HIV) seroprevalence among patients with pulmonary tuberculosis (TB), and compare HIV-positive and HIV-negative TB patients. DESIGN: From July 1995 through June 1996, a cross-sectional study was conducted of newly registered adults (> or =16 years old) with suspected pulmonary TB. RESULTS: Of 2587 newly registered patients with suspected pulmonary TB, 2019 (78%) received HIV pretest counseling and 1816 (90%) consented to testing. Of these, 364 (20%) were HIV-seropositive. Among 1091 patients with bacteriologically confirmed TB, HIV seroprevalence was 22%. HIV-positive patients were more likely to be young, unemployed, single men and to have a history of injection drug use. HIV-positive patients with first-episode TB were more likely to have Mycobacterium tuberculosis strains resistant to isoniazid (10.9% vs 3.5%; P < 0.001), rifampicin (9.4% vs 2.9%; P < 0.001), and at least isoniazid and rifampicin (multidrug-resistant TB [MDR-TB]; 5.2% vs 0.4%; P < 0.001). CONCLUSIONS: HIV prevalence is high among TB patients at this Bangkok hospital and is associated with drug resistance, including a 12 times higher risk of MDR-TB. These findings underscore the urgent need to assure adherence to complete, effective TB treatment regimens for all patients, including persons who are potentially difficult to manage such as injection drug users.  相似文献

SETTING: A large, urban human immunodeficiency virus (HIV) voluntary counseling and testing (VCT) center in Kampala, Uganda. OBJECTIVE: Tuberculosis (TB) is a leading cause of morbidity and mortality in persons with HIV infection in sub-Saharan Africa. Intensified TB case finding and use of isoniazid preventive therapy (IPT) for latent infection reduces the burden of TB, but few programs have been implemented due to concerns about feasibility. DESIGN: Retrospective evaluation of a TB case finding and IPT program. RESULTS: Over a 25-month period, 6305 patients newly diagnosed with HIV infection underwent evaluation: 293 (5%) had TB disease; 1955 (37%) patients were not eligible for preventive therapy because they lived > 20 km away, had advanced HIV disease, or had previously had TB. Of 3366 who had a tuberculin skin test (TST) placed, 2548 (76%) had the TST read; 894 (35%) of these were positive. Of 506 persons who started treatment, 335 (66%) completed it. CONCLUSION: This unique program was feasible, detected a high proportion of undiagnosed TB, and successfully treated persons with latent infection. Expanding access to HIV VCT as well as collaboration between HIV/ AIDS and TB programs can increase the proportion of HIV-infected persons who can benefit from these programs.  相似文献
