Abstract
The number of people infected with tuberculosis continues to rise worldwide. Rifampicin-containing treatment regimens can achieve high cure rates. Intermittent drug treatment delivered in the community has the potential to improve adherence to treatment. The objective of this review was to compare the effectiveness of rifampicin-containing short-course chemotherapy regimens, given two or three times a week, with similar regimens given daily in adult patients with pulmonary tuberculosis. We searched the Cochrane Infectious Diseases Group specialized trials register (January 2003), The Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 4, 2002), MEDLINE (1966 to January 2003), EMBASE (1980 to December 2002), and reference lists of articles. We contacted experts in the field. Randomized and quasi-randomized trials of any multiple drug regimen containing rifampicin in patients with confirmed pulmonary tuberculosis. Treatment had to be given up to three times a week for up to nine months, with any initial daily dosing period not more than one month, and was compared to daily dosing throughout for the same period. Two reviewers independently assessed trial eligibility and quality. One trial involving 399 patients was included. The trial compared treatment three times per week with daily treatment for six months. There was no difference in cure rate (198 out of 199 people in the intermittent group compared to all 200 in the daily group), but 5 patients relapsed in the group receiving intermittent therapy compared to one in the group receiving the daily regimen. There is not enough evidence to assess the equivalence of effect between fully intermittent, rifampicin-containing short-course chemotherapy and similar daily therapy in patients with pulmonary tuberculosis. Larger randomized studies are required to establish the equivalence of fully intermittent, short-course chemotherapy, with daily regimens. Dosis intermitentes para el tratamiento de la tuberculosis en adultos El número de personas infectadas con tuberculosis continúa aumentando en todo el mundo. Los regímenes de tratamiento con rifampicina pueden lograr tasas de curación altas. El tratamiento farmacológico intermitente administrado en la comunidad tiene el potencial de mejorar el cumplimiento del tratamiento. El objetivo de esta revisión fue comparar la efectividad de los regímenes de quimioterapia con rifampicina de corta duración, administrados dos o tres veces por semana, con regímenes similares administrados diariamente en pacientes adultos con tuberculosis pulmonar. Se buscó en el registro especializado de ensayos del Grupo Cochrane de Enfermedades Infecciosas (Cochrane Infectious Diseases Group) (enero 2003), el Registro Cochrane Central de ensayos controlados (Cochrane Central Register of Controlled Trials) (La Cochrane Library Número 4, 2002), MEDLINE (1966 a enero de 2003), EMBASE (1980 a diciembre de 2002), y listas de referencias de los artículos. Se estableció contacto con los expertos en el tema. Ensayos aleatorios y cuasialeatorios de cualquier régimen farmacológico múltiple con rifampicina en pacientes con tuberculosis pulmonar confirmada. El tratamiento debía administrarse hasta tres veces por semana durante nueve meses, con cualquier período de dosificación inicial diario durante no más de un mes, y ser comparado con la dosificación diaria durante el mismo período. Dos revisores evaluaron de forma independiente la elegibilidad y calidad de los ensayos. Se incluyó un ensayo con 399 pacientes. El ensayo comparó el tratamiento tres veces por semana con el tratamiento diario durante seis meses. No había ninguna diferencia en la tasa de curación (198 de 199 personas en el grupo intermitente comparadas con las 200 del grupo diario), pero cinco pacientes recayeron en el grupo que recibió el tratamiento intermitente, en comparación a uno en el grupo que recibió el régimen diario. No hay suficiente evidencia para evaluar la equivalencia de efecto entre la quimioterapia de corta duración intermitente con rifampicina y el tratamiento similar diario en pacientes con tuberculosis pulmonar. Se necesitan estudios más grandes con asignación al azar para establecer la equivalencia de la quimioterapia de corta duración intermitente con los regímenes diarios.Keywords
