RESUMO

This study shows that cabergoline (single oral-dose) is an acceptable, safe and effective drug for suppressing puerperal lactation. It could be of operational benefit not only for artificial feeding, but also for weaning in those that breast-feed within preventive mother-to-child HIV transmission programmes in resource-limited settings.

RESUMO

A study was carried in a rural district in Malawi among HIV-positive individuals placed on antiretroviral treatment (ART) in order to verify if community support influences ART outcomes. Standardized ART outcomes in areas of the district with and without community support were compared. Between April 2003 (when ART was started) and December 2004 a total of 1634 individuals had been placed on ART. Eight hundred and ninety-five (55%) individuals were offered community support, while 739 received no such support. For all patients placed on ART with and without community support, those who were alive and continuing ART were 96 and 76%, respectively (P<0.001); death was 3.5 and 15.5% (P<0.001); loss to follow-up was 0.1 and 5.2% (P<0.001); and stopped ART was 0.8 and 3.3% (P<0.001). The relative risks (with 95% CI) for alive and on ART [1.26 (1.21-1.32)], death [0.22 (0.15-0.33)], loss to follow-up [0.02 (0-0.12)] and stopped ART [0.23 (0.08-0.54)] were all significantly better in those offered community support (P<0.001). Community support is associated with a considerably lower death rate and better overall ART outcomes. The community might be an unrecognized and largely 'unexploited resource' that could play an important contributory role in countries desperately trying to scale up ART with limited resources.

RESUMO

A study was conducted in rural Malawi to verify (a) whether the Partec CyFlow Counter((R)) for CD4+ T-cell lymphocyte counting in HIV-positive individuals could be introduced into a district hospital laboratory and (b) whether it would produce CD4 counts of acceptable quality. CD4+ cell counting was performed using the Partec CyFlow Counter and the results were compared with a reference method (FACsCount). A total of 311 blood samples were analysed and the correlation coefficient for the CyFlow Counter was 0.92 (95% CI 0.89-0.95). Mean CD4 counts using the Partec and the reference methods were 308.2 cells/microl and 316.9 cells/microl, respectively. The mean difference in CD4 count values was -8.68 cells/microl (95% CI -18.8 to 1.4). Mean intra-run variation was -6.84 cells/microl (95% CI -12.9 to 0.79). In the district laboratory setting, the instrument could accommodate up to 75 blood samples per technician per day. After being trained, local laboratory staff found the CyFlow Counter procedures simple to run and the instrument easy to manipulate. The Partec CyFlow Counter produces sufficiently reliable results and the instrument appears robust under field conditions. It could provide a new option for introducing routine CD4+ cell monitoring at the district level in the context of scaling-up antiretroviral therapy in Malawi.

RESUMO

This paper describes (a) the experience of initiating community involvement in HIV/AIDS and tuberculosis (TB) activities in a rural district in Malawi and (b) some of the different ways in which the community is contributing in the fight against these two diseases and the outcomes of their involvement. During a 2-year period, a total of 21,358 (41%) of 52,510 HIV tests performed at voluntary counselling and HIV testing (VCT) sites in the district were conducted by lay community counsellors. A team of 465 community volunteers, 1,362 trained family caregivers and 9 community nurses provided care and support to 5,106 HIV-positive individuals, of whom 2,006 (39%) were in WHO stage III or IV. All those in WHO stage III or IV were on co-trimoxazole prophylaxis and 895 (45%) of these were also on antiretroviral treatment. A total of 2,714 TB patients, of whom 1627 (60%) were HIV-positive, also received care and support. A total of 1,694 orphans were trained in vocational skills. Twelve vegetable gardens and three maize farms were set up, and pre-school activities were organised for 900 orphans. Communities can play an important contributory role in reducing the burden of HIV/AIDS and TB and in mitigating its impact. Despite this, community resources in most settings are often under-exploited and their role remains undefined.

RESUMO

Malawi offers antiretroviral treatment (ART) to all HIV-positive adults who are clinically classified as being in WHO clinical stage III or IV without 'universal' CD4 testing. This study was conducted among such adults attending a rural district hospital HIV/AIDS clinic (a) to determine the proportion who have CD4 counts >or=350 cells/microl, (b) to identify risk factors associated with such CD4 counts and (c) to assess the validity and predictive values of possible clinical markers for CD4 counts >or=350 cells/microl. A CD4 count >or=350 cells/microl was found in 36 (9%) of 401 individuals who are thus at risk of being placed prematurely on ART. A body mass index (BMI) >22 kg/m(2), the absence of an active WHO indicator disease at the time of presentation for ART, and a total lymphocyte count >1,200 cells/microl were significantly associated with such a CD4 count. The first two of these variables could serve as clinical markers for selecting subgroups of patients who should undergo CD4 testing. In a resource-limited district setting, assessing the BMI and checking for active opportunistic infections are routine clinical procedures that could be used to target CD4 measurements, thereby minimising unnecessary CD4 measurements, unnecessary (too early) treatment and costs.

RESUMO

SETTING: Thyolo District Hospital, rural Malawi. OBJECTIVES: In a prevention of mother-to-child HIV transmission (PMTCT) programme, to determine: the acceptability of offering 'opt-out' voluntary counselling and HIV-testing (VCT); the progressive loss to follow up of HIV-positive mothers during the antenatal period, at delivery and to the 6-month postnatal visit; and the proportion of missed deliveries in the district. DESIGN: Cohort study. METHODS: Review of routine antenatal, VCT and PMTCT registers. RESULTS: Of 3136 new antenatal mothers, 2996 [96%, 95% confidence interval (CI): 95-97] were pre-test counselled, 2965 (95%, CI: 94-96) underwent HIV-testing, all of whom were post-test counselled. Thirty-one (1%) mothers refused HIV-testing. A total of 646 (22%) individuals were HIV-positive, and were included in the PMTCT programme. Two hundred and eighty-eight (45%) mothers and 222 (34%) babies received nevirapine. The cumulative loss to follow up (n=646) was 358 (55%, CI: 51-59) by the 36-week antenatal visit, 440 (68%, CI: 64-71) by delivery, 450 (70%, CI: 66-73) by the first postnatal visit and 524 (81%, CI: 78-84) by the 6-month postnatal visit. This left just 122 (19%, CI: 16-22) of the initial cohort still in the programme. The great majority (87%) of deliveries occurred at peripheral sites where PMTCT was not available. CONCLUSIONS: In a rural district hospital setting, at least 9 out of every 10 mothers attending antenatal services accepted VCT, of whom approximately one-quarter were HIV-positive and included in the PMTCT programme. The progressive loss to follow up of more than three-quarters of this cohort by the 6-month postnatal visit demands a 'different way of acting' if PMTCT is to be scaled up in our setting.

RESUMO

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.

RESUMO

SETTING: Thyolo district, Malawi. OBJECTIVES: To determine in HIV-positive individuals aged over 13 years CD4 lymphocyte counts in patients classified as WHO Clinical Stage III and IV and patients with active and previous tuberculosis (TB). DESIGN: Cross-sectional study. METHODS: CD4 lymphocyte counts were determined in all consecutive HIV-positive individuals presenting to the antiretroviral clinic in WHO Stage III and IV. RESULTS: A CD4 lymphocyte count of < or = 350 cells/microl was found in 413 (90%) of 457 individuals in WHO Stage III and IV, 96% of 77 individuals with active TB, 92% of 65 individuals with a history of pulmonary TB (PTB) in the last year, 91% of 89 individuals with a previous history of PTB beyond 1 year, 81% of 32 individuals with a previous history of extra-pulmonary TB, 93% of 107 individuals with active or past TB with another HIV-related disease and 89% of 158 individuals with active or past TB without another HIV-related disease. CONCLUSIONS: In our setting, nine of 10 HIV-positive individuals presenting in WHO Stage III and IV and with active or previous TB have CD4 counts of < or = 350 cells/microl. It would thus be reasonable, in this or similar settings where CD4 counts are unavailable for clinical management, for all such patients to be considered eligible for antiretroviral therapy.

RESUMO

In a rural district in Malawi, poorly motivated health personnel, shortages of human and financial resources, weak dialogue between existing tuberculosis (TB) and human immunodeficiency virus (HIV) programmes and poor community involvement are constraints to establishing joint TB-HIV interventions. The presence of a non-governmental organisation (NGO), Médecins Sans Frontières (MSF), in the health care delivery system provided an opportunity to bridge some of these gaps. The main inputs provided by MSF included additional staff, supplementary drugs including antiretroviral drugs, technical assistance and infrastructure development. The introduction of a scheme of monthly performance-linked incentives for health personnel proved successful in improving their performance, as judged by attendance rates as well as the quality and quantity of activities. This initiative also provided the district management with a tool for exerting pressure on health staff to improve their performance. The availability of independent NGO funds and a logistics team for construction of new infrastructure allowed the rapid initiation of new interventions at the district level without having to wait for disbursements of funds from the central level. This introduced a new dynamic of decentralised operational flexibility at the district level which improved access to care and support for people with TB-HIV.

RESUMO

SETTING: Two rural districts in Malawi: Thyolo, where voluntary counselling and human immunodeficiency virus (HIV) testing (VCT) is offered to all tuberculosis (TB) patients and adjunctive cotrimoxazole to HIV positives, and Mulanje, where no such interventions are offered. OBJECTIVES: For all TB patients registered in 2001: 1) to determine the uptake of VCT and cotrimoxazole in Thyolo, and 2) to compare treatment outcomes between Thyolo and Mulanje. DESIGN: A cohort study using routinely collected programme data. RESULTS: There were 1239 TB patients in Mulanje and 1103 in Thyolo. In Thylo, 1064 (97%) patients consented to VCT, 1006 were HIV tested (91%) and 761 (69%) were started on cotrimoxazole a median of 4 days from registration; 77% of patients tested in Thyolo were HIV-positive. For all TB patients, in Thyolo and Mulanje, treatment success was respectively 75% and 61% (P < 0.001); death was 21% and 25% (P = 0.026); and other outcomes were 4% and 14% (P < 0.001). The adjusted relative risks of treatment success (1.23), death (0.84) and other outcomes (0.26) in Thyolo were significantly different from those in Mulanje (P < 0.001). CONCLUSION: VCT and adjunctive cotrimoxazole is well accepted by TB patients in Thyolo and, with other HIV care and support services, is associated with good treatment outcome indicators for the National Tuberculosis Programme. This intervention is being expanded to other districts in Malawi, and other African countries should consider a similar approach to the dual HIV-TB epidemic.
