Resumen

Introduction:

Cystitis is the most prevalent urinary tract infection (UTI), and antibiotics are its conventional therapy. However, the prevalence rate of antibiotic resistance to uropathogens is significantly increased. Cranberry treatment has been associated with the inhibition of Escherichia coli (Ec) adherence to uroepithelial cells due to the anti-adhesive property related to its proanthocyanidins content, and cysticlean ® (CYS) is a cranberry extract which contains 240 mg PACs per capsule. Since elderly people is one of the populations mostly exposed to cystitis and bacteria antibiotic resistance, it was decided to originally study the efficacy and safety of CYS, to treat cystitis instead of antibiotic, in elderly individuals.

Materials and methods:

Two groups were studied: Group 1 (G1): first cystitis episode was recorded within the last 3 months before the study initiatio. Group 2 (G2): frequent cystitis recurrent episodes (1-2/month or more) within the last 3 months before the study initiation. G1 patients were treated with 1 capsule of CYS every 12 h for 1 month, while G2 patients were treated up to 12 months. Comparative evaluation was performed using Student test.

Results:

160 elderly ambulatory and nursing home patients suffering from recurrent cystitis were treated with CYS. G1 and G2 had 38 and 122 subjects, respectively. Cranberry-based cystitis treatment was successful in 81.57 % and 81.96 % in G1 and G2 patients, respectively.

Conclusions:

CYS showed to be an effective alternative therapy to antibiotics totreat cystitis recurrences caused by Ec. Neither side effects nor adverse reactions have been reported.

 

Introducción:

La cistitis es la infección del tracto urinario más común a nivel mundial y los antibióticos son su terapia convencional; sin embargo, la tasa de prevalencia de la resistencia de los uropatógenos a los antibióticos ha aumentado significativamente en los últimos tiempos. El tratamiento con arándano rojo se ha asociado con la inhibición de la adherencia de la Escherichia coli a las células uroepiteliales debido a la propiedad antiadherente relacionada con su contenido de proantocianidinas. La cysticlean® (CYS) es un extracto de arándano rojo que contiene 240 mg de PAC por cápsula.

Objetivo:

Estudiar la eficacia y seguridad de la CYS en el tratamiento de la cistitis como reemplazo de los antibióticos en personas adultas mayores.

Materiales y métodos:

Se estudiaron dos grupos, uno (G1) en el que el primer episodio de cistitis se registró dentro de los últimos 3 meses antes del inicio del estudio y otro (G2) en el que se registraron episodios recurrentes de cistitis frecuentes (?1-2 al mes) en los últimos 3 meses antes del inicio del estudio. Los pacientes del G1 fueron tratados con 1 cápsula de CYS cada 12 horas durante 1 mes, mientras que los del G2 fueron tratados por 12 meses con el mismo esquema. La evaluación comparativa se realizó mediante la prueba de Student.

Resultados:

En el estudio participaron 160 pacientes ambulatorios de la tercera edad residentes de hogares de ancianos y con diagnóstico de cistitis recurrente. De estos, 38 se incluyeron en G1 y 122, en G2. El tratamiento de la cistitis a base de arándano rojo tuvo éxito en el 81,57 % y el 81,96 % de los pacientes de G1 y G2, respectivamente.

Conclusión:

La CYS demostró ser una terapia alternativa eficaz a los antibióticos para tratar las recurrencias de cistitis causadas por E. coli al no presentarse efectos secundarios ni reacciones adversas.
