Replacement of streptomycin by ethambutol in the intensive phase of tuberculosis treatment: no effect on compliance.

SETTING: Seven tuberculosis clinics in the National Tuberculosis Programme of Madagascar. OBJECTIVE: To compare the treatment efficacy and tolerance of regimens including either streptomycin or ethambutol for patient compliance during initial treatment of smear-positive tuberculosis. DESIGN: The 1023 patients included in the study were randomly divided into two treatment groups-one to receive streptomycin (S), isoniazid (H), rifampicin (R) and pyrazinamide (Z) (SHRZ), and the other to receive EHRZ, where streptomycin was replaced by ethambutol (E). During the 2-month intensive phase, drug delivery was completely supervised. The same 6-month continuation regimen was then given in both groups. Follow-up consisted of a clinical and bacteriological examination at the end of the second, fifth and eighth months. RESULTS: There was no significant difference between the two regimens as regards compliance with treatment, the number of patients lost or who died, or for bacteriological response during the intensive phase. EHRZ was better tolerated. During the continuation phase, the results of the two groups remained comparable, but treatment failures occurred earlier in the patients who had received streptomycin. CONCLUSION: Patient compliance was not better with streptomycin. The ethambutol-containing regimen was as efficient as the other, and better tolerated. There is no argument for preferring streptomycin in the intensive phase of treatment of smear-positive tuberculosis.

[Microscopy laboratories for the diagnosis of tuberculosis in Madagascar: quality control].

As part of the National Tuberculosis Program (NTP), a quality control of the slides (search of acido-fast-bacilli in the sputa) of the Treatment and Diagnosis Centers (TDC) forming the National Laboratory Network was carried out in 1996. 60 TDC of the 165 TDC (36%) had been controlled according to the system of double reading of the smears. The global concordance of the results in the 60 TDC is satisfactory since it was of 94%. Reliability of smears positive was of 83%. For the negative smears reliability, 14% of the TDC had a low or insufficient level. A good quality of smears was observed in 40% of the centers. The TDC that had both positive and negative reliability at 100% were 23 (38%) of which 13 had good quality of smears. Those were especially found in Antananarivo, Toliara, Fianarantsoa and Mahajanga.

[Role of catholic centers in the control of tuberculosis].

This study briefly reports the results of a survey conducted by the National Tuberculosis Control Programme (NTCP) to asses the Catholic Centres and particularly the leper colonies activities of tuberculosis control. Among the 34 Catholic Centres taking care of the lepers, 11 take part in the NTCP. Within less than 3 years, most of these centres have taken charge of twice more tuberculous patients: the number of cases increased from 540 to 1045. Leprosy prevalence is constantly decreasing, thus multibacillary leprosy cases declared by these centres decreased of 28% from 1992, to 1994. Centres which did not begin conversion would feel this necessity soon. Germs responsible for leprosy and for tuberculosis are "first cousins". Technical and operational approaches for the control of both affections are very much alike. Those considerations logically induce to propose the conversion of antileprosy centres for tuberculosis control. Other arguments are partially exposed in this work. The Central Division knows the existence of 28 Catholic Centres throughout the country, taking charge of tuberculous patients. In 1994, they put more than 1600 patients under treatment, thus 15% of the tubercular in Madagascar. Those Catholic Centres implementing tuberculosis control programme ought set up a "federation" as a privileged interlocutor for the NTCP and for the financial backers when allowing support. Responsibles of the Programme expect to convince Centres of the necessity of conversion and of the interest of tuberculosis control.

[The National Tuberculosis Control Program in Madagascar].

In 1991, the National Tuberculosis Control Program could start in Madagascar, thanks to the financial support of the French Cooperation. Within 3 years, this allocation of resources allowed the management, respecting the new standards, of 56% of the country's health structures and of more than 75% of the sick. The number of detected and treated patients increased of 80%. During the same period, the recovery rate increased from less than 35% to more than 65%. Those primary results were satisfactory in terms of working but they were not enough in epidemiological terms as the aims were still far: the detection rate of smear-positive pulmonary tuberculosis was 40% whereas it ought be 60%, and their recovery rate was 65% whereas it ought to be over 80%. The geographic extension of the Program and its progress depend on a structural strengthening needing an obvious political will and on the intervention of financial partners cooperating with France and willing to set up a long lasting partnership.

[Role of the Lutheran Non-Governmental Health Organization in tuberculosis control].

Ever since its establishment in Madagascar, the Lutheran Church has been very active in medical field. In 1983, the creation of a medical non governmental organization called SALFA (Sampanasa Loteriana momba ny Fahasalamana) gave a new impulse. Since 1987, the SALFA has been seriously involved in the management of tuberculous patients. This document is a synthesis of actions conducted by SALFA whose experience in tuberculosis control is widely recognized by the Health Department and specially by the National Tuberculosis Control Program (NTCP). With an annual average of 1250 tuberculosis taken in charge, this NGO assumes 10% of the whole of the Program work. The diagnosis work is good (more than 85% Of PMT+) and therapeutic follow up of patients is excellent (more than 80% of the cured); those two elements of screening-treatment, basis of all tuberculosis control program incited us to describe this exemplary program.

[Profile of the patients lost to treatment in the National Anti-Tuberculosis Program in Madagascar].

A national anti-tuberculosis program has been in operation in Madagascar since 1991. Despite the significant efforts made in the management, education and surveillance of patients, the number of patients lost to treatment remains high (18.8%). Noncompliance with treatment is the principal cause of treatment failure and of the development of resistance to tuberculosis drugs. This study investigated the profile of the patients who discontinue treatment. The study population consisted of the patients withdrawing from a clinical trial carried out between August 1994 and September 1996. The aim of the trial was to compare several treatments in routine practice conditions in Madagascar. The treatments tested were streptomycin (S) or ethambutol (E) associated with isoniazid (H), rifampicin (R) or pyrazinamide (Z) for the first two months, followed by 6 months of treatment H and thiacetazone (T). The trial involved four public and three private diagnosis and treatment centers in Antananarivo, Fianarantsoa and Mahajanga. A total of 1, 023 patients were included in the trial and 192 (18.8%) withdrew during the eight-month treatment period. We tracked down 109 of these patients (56.8%) and 19 patients came back to the treatment center on their own initiative for a checkup. The rate of response to a recall letter sent by mail was low. The 106 patients interviewed mostly gave professional, financial or family reasons for discontinuing treatment. Many patients stopped the treatment as soon as they began to feel better. To reduce the number of patients discontinuing treatment, the National Anti-Tuberculosis Program should improve the education of patients and their families.
