Background

Clinical experience raises suspicion that the Spanish population could suffer higher rates of side effects of sulfasalazine (SSZ) therapy. We conducted a systematic review of existing literature to analyze the susceptibility to developing adverse events produced by SSZ in the Spanish population.

Material and method

A literature search was conducted in EMBASE, IBECS, and MEDLINE from 1973 to March 2007. The items sought were those describing adverse effects, both in text and tables, and reasons for withdrawal, the population under study and discussion of differences in side effects of the different treatment groups.

Results

Of the 106 retrieved articles, 36 were selected for review and detailed analysis. 34 articles were selected from MEDLINE and EMBASE and 2 from IBECS. We did not find any study that showed that the Spanish population was more susceptible to SSZ.

Conclusions

The adverse effects of SSZ vary with the pattern of acetylation. Thus, in slow-acetylators, depending on the dosage of SSZ, the side effects increase significantly. In the Spanish population slow-acetylators prevalence is higher than in other ethnic groups. Therefore, one could infer that the incidence of adverse side effects by SSZ could be higher in the Spanish population than in others different ethnic groups. We found no evidence that the Spanish population was more likely to suffer adverse effects by SSZ than other ethnic groups.

Introducción

La experiencia clínica hace sospechar que la población española pudiera sufrir más efectos adversos por la sulfasalazina (SSZ). Se realizó una revisión sistemática de la literatura existente con el objetivo de analizar la susceptibilidad a desarrollar eventos adversos producidos por la SSZ en la población española.

Material y método

Se definió una estrategia de búsqueda bibliográfica sensible en EMBASE, IBECS y MEDLINE desde 1973 hasta marzo de 2007. En los artículos seleccionados se buscó la descripción de los efectos adversos, tanto en el texto como en las tablas, así como los motivos de retirada, la población estudiada y la discusión sobre la opinión de las diferencias en los efectos adversos de los diferentes grupos de tratamiento.

Resultados

De un total de 106 artículos rescatados se seleccionaron 36 para realizar un análisis detallado de los 34 artículos seleccionados en MEDLINE y EMBASE y de los 2 de IBECS. No se encontró ningún estudio que evidencie que la población española sea más susceptible a los efectos adversos por SSZ.

Conclusiones

Los efectos adversos por SSZ varían según el patrón de acetilación. En la población española la prevalencia de acetiladores lentos es mayor que en otros grupos étnicos; por tanto, cabría inferir que la incidencia de efectos adversos secundarios a la SSZ podría ser mayor en la población española que en otros grupos. No encontramos evidencia en la literatura de que la población española sea más susceptible a los efectos adversos por la SSZ.
