Abstract
In some Latin American countries, discontinuation of treatment when immunosuppressive drugs are unavailable can cause late renal graft loss. This retrospective study reports the frequency and consequences of interrupted treatment at a single center in Venezuela. In 2005 and 2006, we evaluated the medical records of and interviewed 303 patients (181 males) followed for more than one year after renal transplantation done between 1973 and 2005. Noncompliance for 1 week was reported by 124 patients; 107 (86.3 percent) instances were due to unavailability of immunosuppressive drugs at the institution (institutional noncompliance), and the remainder were due to voluntary noncompliance. Acute rejection episodes were about three times as frequent among voluntary noncompliers as institutional noncompliers, probably because voluntary noncompliance lasted longer (mean 42.7 ± standard deviation of 14.1 days) than institutional noncompliance (18.5 ± 11.2 days, P 0.001). Graft loss occurred in 63.6 percent (7/11) of the episodes of voluntary noncompliance and in 33.3 percent (10/30) of the episodes of institutional noncompliance. Institutional noncompliance represents a preventable cause of graft loss in some transplantation programs in developing countries.(AU)
 
En algunos países de América Latina, la interrupción del tratamiento cuando no se dispone de los medicamentos inmunosupresores puede causar la pérdida tardía del trasplante renal. Este estudio retrospectivo informa la frecuencia y las consecuencias de la interrupción del tratamiento en un centro en Venezuela. Se entrevistaron 303 pacientes (181 de ellos del sexo masculino) que tenían un seguimiento de más de un año después del trasplante renal y se evaluaron sus historias clínicas. Ciento veinticuatro pacientes informaron haber interrumpido el tratamiento por más de 1 semana; en 107 (86,3 por ciento) casos el motivo fue no disponer de los medicamentos inmunosupresores en la institución (incumplimiento institucional) y el resto se debió a incumplimientos voluntarios. Los episodios de rechazo agudo fueron cerca de tres veces más frecuente en los incumplidores voluntarios que en los incumplidores institucionales, probablemente porque el incumplimiento voluntario duró más (42,7 ± 14,1 días [desviación estándar]) que el institucional (18,5 ± 11,2 días; P 0,001). La pérdida del trasplante ocurrió en 63,6 por ciento (7/11) de los incumplimientos voluntarios y en 33,3 por ciento (10/30) de los incumplimiento institucionales. El incumplimiento institucional es una causa evitable de pérdida del órgano transplantado en algunos programas de trasplante en países en desarrollo.(AU)
