RESUMEN
BACKGROUND: Percutaneous insertion of a peritoneal dialysis catheter (PDc) is an alternative to open surgical techniques, and the anatomical characteristics of the abdominal wall may predict PDc dysfunction. We evaluated the role of rectus abdominis muscle (RAM) thickness as a predictor of PDc dysfunction. MATERIALS AND METHODS: A prospective cohort of emergency-start PD patients (EmPD) who had their first percutaneous PDc insertion were included. PDc failure was defined as the removal of a PDc due to mechanical failure within the first 30 PD fluid exchanges. Clinical variables were recorded. The skin to parietal peritoneum depth and RAM thickness were determined by abdominal ultrasound. Univariate and multivariate logistic regression models were developed to test associations between clinical parameters and PDc dysfunction. RESULTS: Over 6 months, 119 patients underwent PDc insertion; 73 (61.3%) were males, with a mean age of 46.0 ± 17.8 years. The mean skin-to-peritoneum depth was 2.5 ± 1.0 cm, the RAM thickness was 0.91 ± 0.3 cm, and catheter implantation was successful in 116 (97.4%) patients. Insertion failed in 3 (2.5%) cases, and 30 (25.8%) patients presented with catheter dysfunction. Univariate analysis indicated that RAM thickness ≥ 1.0 cm, skin-to-peritoneum depth > 2.88 cm, abdominal waist > 92.5 cm, and skin-to-RAM fascia distance > 2.3 cm were associated with PDc dysfunction; in multivariate logistic regression analysis, only greater RAM thickness remained a significant predictor (OR 1.6, 95% CI 1.38 - 1.88, p < 0.001). CONCLUSION: In EmPD patients, RAM thickness is associated with PDc dysfunction and could aid in identifying patients at risk for PDc dysfunction in emergency settings. Additional adequately powered studies are needed to confirm our findings.

Chronic degenerative disorders have become a major health problem in Mexico. Cardiovascular diseases represent the first cause of death in our country. Diabetes mellitus (DM) has emerged as the main health problem in Mexico. Its prevalence doubled from < 3% in the 1960s to 6% in the 1980s. Between 1993 and 2000, diabetes mellitus increased from 6.7% to 8.2%, a 22% growth over a seven-year period. In 1995, the cost of the treatment of DM represented 15.48% of the health budget and 0.79% of the GDP. The prevalence of hypertension (HTN) increased from 10% in 1933 to 20% in 1990 and from 23.8% to 30.7% between 1993 and 2000. The expenditures from HTN in 1999 corresponded to 13.9% of the health budget, and 0.71% of GDP. Dyslipidemias are very common. Close to 40% of the population has levels of HDL cholesterol < 35 mg/dL, 24.3% has fasting triglycerides > 200 mg/dL, and 10% has hypercholesterolemia. The prevalence of obesity increased from 21.4% in 1993, to 23.7% in the year 2000. Eight percent of the population has a glomerular filtration rate < 60 mL/min, and 9.1% has proteinuria. Twenty-four percent uses tobacco regularly, and 13% had the habit in the past. Smoking is more frequent among diabetics (34%).In conclusion, cardiovascular risks factors are highly common among the Mexican population and increasing at alarming rates. Preventive programs targeted to decrease their prevalence are urgently needed in Mexico and should become a national priority.
