Objective: To determine whether patients with chronic kidney disease (CKD) without dialysis their stage impacts the native vitamin D levels. Methods: Patients over 18 years with chronic kidney disease stage 2-5 without dialysis treatment. They demographic, anthropometric variables, degree of sun exposure, disease etiology and laboratory variables related to bone and mineral disorders were evaluated. Study analytical cross-sectional prospective. Descriptive statistical methods for quantitative and qualitative are characterized, and analytical correlation between levels of vitamin D statistical laboratory tests related to bone and mineral disorders, sun exposure and ethnicity variables for each stage were characterized. By descriptive statistical methods, quantitative and qualitative variables were characterized, and analytical statistical correlation between levels of vitamin D with laboratory tests related to bone and mineral disorders, sun exposure and ethnicity for each stage were practiced. Results: 331 patients were evaluated, with a mean age of 71 years, the mestizo majority (71%), 173 women, main etiology of CKD hypertensive nephropathy (33.2%). 21.1% of patients had normal levels of vitamin D, 70.1% insufficient, and 8.8% in deficit. Negative correlation was detected between the levels of vitamin 25(OH)D and serum creatinine, phosphorus, calcium x phosphorus product, PTH, proteins in urine 24 hours and BMI. Positive correlation for calcium and albumin. Positive statistical significance between the levels of vitamin 25(OH)D and sun exposure for 3b and 4 stages was found. Conclusions: In patients with CKD is common to detect low levels of vitamin 25(OH)D, which can contribute to the generation of secondary hyperparathyroidism.
This corrects the article "Vitamin D (25 ( OH) D ) in patients with chronic kidney disease stages 2-5" in volume 47(3) on page 163, Table 3. The September 30, 2016, article by Restrepo and Aguirre (Colomb Med (Cali). 2016;47(3): 160-6, was published with errors in Table 3. In body of Table 3, the sixth line of the first column entitled PH (pg/mL), this should read: PTHi (pg/mL). The sixth line of the eight column reads: 11.65, this should read: 116.5. That date appears well in the English XML version, but in both the PDF ingles and the Spanish version appears the value 11.65, must be changed to the real value: 116.5.
Objetivo: establecer si la implantación de catéteres femorales tunelizados de 23 cm genera mejores resultados que los de 19 cm.Pacientes, materiales y métodos: pacientes con enfermedad renal crónica estadio 5, en los que se agotaran todos los accesos vasculares, siendo la vena femoral su última alternativa. En ellos se compararon los resultados en cuanto a eficiencia y complicaciones de implantar catéteres con diferente longitud.Resultados: durante 103 meses (de febrero del 2009 a septiembre del 2017), 30 catéteres femorales tunelizados fueron implantados en 19 pacientes; 15 en cada grupo, edad promedio de los pacientes 56,3 años, 13 (68,4%) hombres. Los dos catéteres con diseño semejante, pero diferente longitud dieron lugar a resultados parecidos en cuanto a tiempo de funcionamiento, complicaciones y motivo de retiro.Conclusiones: sugerimos que los catéteres femorales tunelizados para hemodiálisis deben de tener longitudes entre 28 a 55 cm (del retenedor a la punta) para lograr una mayor eficiencia, longitud suficiente que permita alcanzar territorios cercanos a la aurícula derecha.
