Objetivo: La peritonitis es una de las principales comorbilidades que presentan los pacientes en diálisis peritoneal (DP). El objetivo de este estudio es centrarnos en los posibles factores de riesgo, incluidos los de más reciente estudio entre los ya clásicos factores de la peritonitis en pacientes en DP. Materiales y métodos: Analizamos 109 pacientes (H/M = 67/42) sometidos a seguimiento durante al menos tres meses en un único centro, un hospital terciario con una tasa de 360,1 años-paciente. En este trabajo, concebido como un estudio de cohorte retrospectivo, se registraron las características demográficas, las condiciones que llevaron a la DP, tipo de DP, pruebas químicas y episodios de peritonitis. Esta información se extrajo de los historiales. Resultados: Se descubrió que la tasa de peritonitis era de 0,22 episodios/años-paciente y 22 (20,18%) pacientes habían padecido más de un episodio. Veintisiete (24,8%) de los pacientes recibían DP por obligación. Gracias al análisis de regresión múltiple, se descubrió que los factores relacionados eran el tipo de llegada al tratamiento (obligatoria frente a voluntaria) (p = 0,04; RR = 2,6), los niveles de albúmina sérica (p = 0,05; RR = 1,2), y la positividad para anticuerpos contra el virus de hepatitis C (p = 0,03; RR = 1,6). La frecuencia de pacientes mujeres era significativamente mayor en el grupo que había padecido múltiples episodios (p = 0,01). Conclusión: La remisión obligatoria, que puede ser un indicio de la falta de motivación por los procedimientos de DP, es un importante factor de riesgo de peritonitis en los pacientes en DP y merece ser objeto de estudio. Como era de esperar, los pacientes con múltiples episodios presentaron una mayor frecuencia de remisión obligatoria y además, el número de mujeres era mayor en comparación con el grupo que había padecido un único episodio.

Aim: Peritonitis is one of the major comorbidities of peritoneal dialysis (PD) patients. The aim of this study was to concentrate on potential risk factors, including more recently studied ones among the classical ones for peritonitis, in PD patients. Materials and methods: We analysed 109 patients (F/M = 42/67) followed up at least for 3 months in a single centre, a tertiary referral hospital for 360.1 patient years. In the study which is designed as a retrospective cohort study, demographic characteristics, conditions for choosing PD, type of PD treatment, some chemical tests and peritonitis episodes were recorded from the files of the patients. Results: The rate of peritonitis was found to be 0.22 episode/patient year and 22 (20.18%) of the patients had more than one episode. Twenty seven (24.8%) of the patients were allocated to PD due to obligatory reasons. According to multiple regression analysis, the assosciated factors were found to be PD allocation type (obligatory versus voluntary) (p = 0.04; RR = 2.6), serum albumin level (p = 0.05; RR = 1.2), and anti-hepatitis C Virus Antibody positivity (p = 0.03; RR = 1.6). Frequency of female patients were significantly higher in the group who had multiple episodes (p = 0.01). Conclusion: Obligatory referral which can be an indication of loss of motivation for peritoneal dialysis procedures, is thought to be a strong risk factor for peritonitis in PD patients and should be further studied. Patients with multiple episodes had a higher frequency of obligatory referral as expected and additionally, they were higher in number of females when compared to the ones with single episode.
