'When I Get Better I will do the Test': Facilitators and Barriers to HIV Testing in Northwest Region of Cameroon with Implications for TB and HIV/AIDS Control Programmes

The World Health Organization has recommended collaborative activities between TB and HIV programmes with routine counselling and testing for HIV among TB patients in order to improve the uptake of HIV services. We carried out qualitative research interviews with 21 TB patients in four selected TB and HIV/AIDS treatment centres in the Northwest Region of Cameroon to explore the facilitators and barriers to HIV testing. The desire to be healthy and live longer from knowing one's status inspired by the anticipated support from loved ones; faith in a supreme being; influence and trust in the medical authority; encouraged HIV testing. Men also demonstrated their masculinity by testing; thus portraying themselves as positive role models for other men. Meanwhile; the overwhelming burden of facing both TB and HIV simultaneously; influenced by the fear of disclosure of results; harmful gender norms and practices; fear of stigma and discrimination; and misconceptions surrounding HIV/AIDS deterred HIV testing. However; as a result of conflicting emotional experiences regarding to test or not to test; the decision-making process was not straightforward and this complex process needs to be acknowledged by health care providers when advocating for routine HIV testing among TB patients

Home deliveries: implications for adherence to nevirapine in a PMTCT programme in rural Malawi.

Although nevirapine (NVP) is provided by prevention of mother-to-child-transmission (PMTCT) of HIV programmes to be taken at onset of labor independent of place of delivery, few studies have assessed adherence to NVP outside the hospital setting. This study aimed to follow women in a PMTCT programme up to delivery and to assess the adherence to the prophylaxis in rural Malawi. A total of 75 HIV-positive women were registered in the PMTCT at Malamulo SDA hospital between January and June 2005. Forty women (53%) delivered in the hospital and 35 (47%) did not. Of the 35 women who delivered at home, it was possible to trace 27 (77.2%). All women who delivered in the hospital took their NVP tablets and all their babies had NVP syrup except one baby who died soon after delivery. Of the 27 traced women who had not delivered in the hospital, 16 (59.3%) had access to NVP and had taken their tablets during labor. However, none of their babies was taken back to the health facility for NVP syrup. Traditional birth attendants might be crucial in efforts aiming to increase adherence to NVP among women and their babies.

Anti-tuberculosis treatment in private pharmacies, Kathmandu Valley, Nepal.

SETTING: Urban municipality of 150000 citizens in Kathmandu Valley, Nepal. OBJECTIVE: To determine 1) the perceptions among private pharmacists of characteristics of tuberculosis (TB) patients visiting private pharmacies in the area, 2) the sales of different anti-tuberculosis drugs, and 3) the interaction between private health providers and pharmacists. DESIGN: Between January and April 1998, semi-structured interviews were conducted with 98% (49/50) of the private drug-retailers in the area. RESULTS: Thirty-two (65%) pharmacies had sold anti-TB drugs during the last month. Forty-three (88%) said that most TB patients were of low socio-economic status and rarely bought drugs for more than a week at a time. Only eight (16%) reported that TB patients usually returned to buy the full course of drugs. Seventy-two per cent of total spending on anti-tuberculosis drugs was for different kinds of combinations of drugs. Nine per cent was spent on plain rifampicin, believed to be sold only to tuberculosis/leprosy patients. During the previous month, 5/13 (38%) of pharmacies with no doctors attached had sold anti-tuberculosis drugs compared with 27/38 (71%) of pharmacies with doctors attached to them (P < 0.05). CONCLUSION: The private sector offers an available and acceptable but non-affordable service for many TB patients. A substantial amount of anti-TB drugs are being sold in the private pharmacies. There is therefore a potential role for pharmacists to play in collaborative efforts between the private and public sector in TB control activities.

Sputum examination for acid-fast bacilli in private laboratories, Kathmandu Valley, Nepal.

OBJECTIVE: To investigate the characteristics of private laboratories and the process of sputum examination for acid-fast bacilli (AFB). DESIGN: A door-to-door survey of private laboratories in an urban municipality of Kathmandu valley was conducted during the first quarter of 1998. Semi-structured interviews were conducted with staff of 14/20 (70%) identified laboratories. RESULTS: All 14 private laboratories conducted sputum examination for AFB. The majority (71%) of staff lacked special training for AFB examinations. Monocular microscopes were commonly used (36%). Reagents were prepared irregularly, without quality control, and kept for as long as they lasted, often up to 4-6 months (43%). Laboratory registers were usually present (86%), but lacked information on patient's address and the purpose of the test. A median of 12.5 slides per laboratory had been examined during the previous month (range 0-70). A total of 235 AFB slides were examined, of which 18 (7.7%) were reported as positive. CONCLUSION: AFB examinations were widely available. Lack of training and quality control suggest a variable standard of AFB test results. It is recommended that the National Tuberculosis Programme (NTP) provide support and quality control to two to three (i.e., one for every 10) private laboratories in the area to secure private doctors' confidence in sputum testing.

Tuberculosis control and directly observed therapy from the public health/human rights perspective.

Directly observed therapy, short course (DOTS) is the current international strategy for controlling tuberculosis. Decisions have been taken internationally about the increasing tuberculosis epidemic-what to do and why to do it. But do we know bow the DOTS strategy can be implemented most appropriately and what changes need to be made to ensure that it is effective? This paper uses the Public Health/Human Rights framework to discuss TB control from a human rights rather than the biomedical perspective. The aim is to introduce different approaches to the current DOTS strategy in order to find more effective and appropriate ways to treat and care for people with tuberculosis. The paper argues that key dimensions of social, economic and physical access to TB services need to be assessed and accounted for in programme design. This will require that TB control adopt a wider interdisciplinary and multisectoral perspective to complement the current biomedical orientation.

Syphilis in pregnant women and their children in the United Kingdom: results from national clinician reporting surveys 1994-7.

OBJECTIVE: To measure the incidence of syphilis detected in pregnancy and congenital syphilis in the United Kingdom. DESIGN: Surveys through consultants in genitourinary medicine and paediatricians with active surveillance. SETTING: United Kingdom, 1994-7. SUBJECTS: Women treated for syphilis in pregnancy, and children with early congenital syphilis born in the United Kingdom. RESULTS: Over 3 years 139 women were diagnosed with and treated for syphilis in pregnancy; 121 were detected through antenatal screening. Thirty one had confirmed or probable congenitally transmissible syphilis, putting their pregnancies at risk. These were minimum figures but are compatible with the 90 to 100 women newly diagnosed annually as having infectious or early latent syphilis. A universal screening policy would require 18 600 and 55 700 women (maximum numbers) to be screened, respectively, to detect one woman needing treatment and to prevent one case of congenital syphilis. Nine presumptive cases of children with congenital syphilis born in the United Kingdom were reported. Mothers requiring treatment for syphilis were found in almost every health region but were more prevalent in London and the south east. Being born abroad and belonging to an ethnic minority group were strong risk factors, but 14% (19 of 121) of cases treated and six of 31 definite or probably transmissible cases occurred in white women born in the United Kingdom. CONCLUSIONS: Congenitally transmissible syphilis continues to occur among pregnant women in the United Kingdom. Cases would be missed and stillbirths and congenitally infected babies would occur if antenatal screening was abandoned.
