Factores asociados con el cambio temprano de catéter de diálisis peritoneal en Veracruz, México / Factors associated with early peritoneal dialysis catheter replacement in Veracruz, Mexico

Antecedentes: Las complicaciones asociadas con el catéter en diálisis peritoneal causan disminución en su eficacia e interrupción de ésta, conversión a hemodiálisis, hospitalizaciones y necesidad de cirugía para cambiar el catéter. Objetivos: Determinar factores de riesgo para la disfunción temprana del catéter que hace necesario su cambio. Métodos: Se incluyeron 235 catéteres colocados con técnica quirúrgica abierta en línea media infraumbilical. Dentro de los posibles factores de riesgo se incluyó: edad, género, índice de masa corporal, área de superficie corporal, diabetes, enfermedad poliquística renal, cirugía previa, tiempo quirúrgico, omentectomía, omentopexia, infección de la herida y hernia posincisional. Resultados: El cambio del catéter por disfuncionalidad ocurrió en 47 pacientes (20%) durante el primer año. La complicación más frecuente fue: migración del catéter y peritonitis (4,3% en ambos casos), además de obstrucción por el omento (3,7%). En el análisis univariado, los pacientes que presentaron disfunción del catéter/cambio eran jóvenes con índice de masa corporal y área de superficie corporal bajos (p < 0,05). La infección de la herida y la hernia posincisional estaban asociados significativamente con el cambio de catéter. La omentectomía fue asociada a baja incidencia de disfunción de catéter/cambio en el análisis univariado y regresión logística (razón de momios: 0,275, intervalo de confianza: 95%, 0,101-0,751, p < 0,012). Conclusiones: Nuestra técnica de inserción de catéter ofrece bajas tasas de complicaciones y buenos resultados el primer año posquirúrgico. Además de la omentectomía, en nuestro estudio no se encontró un factor de riesgo para cambio de catéter en nuestra población. La omentectomía tuvo un efecto protector en términos de cambio de catéter (AU)

Introduction: Catheter-related complications in patients on peritoneal dialysis lead to decreased effectiveness and discontinuation of the technique, conversion to haemodialysis, hospitalisation, and surgical interventions to replace the catheter. Objectives: Determine risk factors for early catheter dysfunction that result in the need for replacement. Methods: We analysed 235 catheters placed by open surgery using an infra-umbilical midline incision. Possible risk factors included the following: age, sex, body mass index, body surface area, diabetes, polycystic kidney disease, previous surgery, time of surgical procedure, omentectomy, omentopexy, wound infection and postoperative incisional hernia. Results: During the first year, 47 patients (20%) required a catheter replacement due to poor function. The most common complications were catheter migration and peritonitis (4.3% in both cases), followed by obstruction from omental wrapping (3.7%). Univariate analysis showed that patients with catheter dysfunction or requiring catheter replacement were younger, with a lower body mass index and body surface area (P<.05). There was a significant association of wound infection and post-operative incisional hernia with catheter replacement. Omentectomy was associated with a low incidence rate of catheter dysfunction/replacement in the univariate and logistical regression analyses (odds ratio: 0.275; 95% confidence interval: 0.101-0.751; P<.012). Conclusions: Our catheter placement technique offers a low complication rate and good results in the first year after surgery. Except for omentectomy, we did not discover any risk factors for catheter replacement in our study population. Omentectomy had a protective effect in terms of catheter replacement (AU)

Long-term results after conversion from calcineurin inhibitors to sirolimus in renal transplant patients.

UNLABELLED: BACKGROUND: Calcineurin inhibitors (CNI) toxicity is one of the contributing factors for the development and progression of chronic allograft dysfunction (CAD). Conversion to sirolimus (SRL) from CNI improves renal function kidney in transplant recipients. METHODS: A retrospective review from patients abruptly converted from CNI to SRL over a three yr period is reported. RESULTS: Thirty-nine patients were converted 55.2±58 months after renal transplantation. 24 month patient and graft survival was 100% and 92%. Acute rejection incidence was 7.6%. Overall, serum creatinine (SCr) and Cockcroft-Gault creatinine clearance (CGCrCl) improved. In responders, SCr improved from 2.48±0.8 to 1.94±0.8 mg/dL (p<0.05) CGCrCl improved from 37.8±17.4 to 51.9±23.8 mL/min at two years. An increase in proteinuria was observed from conversion to month 12 in responders (189.4±512.8 to 488.3±890.6 mg/day, p<0.05) and from conversion to month six in non-responders (1179.4±2001.1 to 2357±4172.9 mg/day, p<0.05). Low proteinuria had positive predictive value for renal response after conversion. CONCLUSION: Conversion from CNI to SRL with CAD is associated with improved renal function with an increase in proteinuria. Low proteinuria is a possible positive predictive factor for successful conversion.

Abdominal wall hernias in end-stage renal disease patients on peritoneal dialysis.

OBJECTIVE: To describe our experience with hernioplasty in peritoneal dialysis patients and to identify possible risk factors for surgical complications. DESIGN: A 4-year retrospective chart review of data. SETTING: Peritoneal dialysis unit of a university hospital. PATIENTS AND METHODS: 58 hernias in 50 patients were included. Detailed surgical technique and complications were recorded. Possible risk factors included age, gender, weight, height, body mass index, previous surgery, diabetes, time on dialysis, emergency surgery, hospital stay, type of hernia, mesh use, blood hemoglobin, and serum urea, creatinine, and potassium. RESULTS: Complications occurred in 12 hernioplasties (4 wound infections, 2 peritonitis, 4 catheter dysfunction, and 5 re-operations). Recurrence rate was 12% without mesh use and 0% with mesh hernioplasty. Dialysis was re-instituted in 96% of cases within 3 days postoperatively. Identified risk factors for complications were diabetes, low weight, low height, small body mass index, and low serum creatinine. CONCLUSIONS: Mesh hernioplasty in peritoneal dialysis patients is advisable. Postoperative dialysis with low volume is feasible after surgery. Prospective studies will corroborate our risk factors for morbidity.
