Background

The indication of two hemodialysis (HD) sessions per week is a common strategy in patients with chronic kidney disease without social security. Some studies reveal that the indication of fewer HD sessions per week has been shown to be associated with adequate clinical results.
Objective: To describe the clinical and biochemical status of patients in HD program twice a week in the last five years

Methods

Retrospective cohort study of patients with two HD sessions per week. Their clinical, nutritional status was evaluated by vectors of impedanciometry and quality of life KDQOL-SF 36. The statistical package SPSS V 22.0 was used for data analysis.

Results

Forty-one patients with a mean age of 37.9 ± 12.6 years, 56% women, were analyzed. The mean time with renal replacement therapy was 5.1 years; Average session time was 180 minutes; average ultrafiltration of 2726.8 ± 755.98 ml / session and an average Kt / V single pool of 1.54 ± 0.38. In 59% of patients the cause of CKD was undetermined. 46% of the patients had an arteriovenous fistula. Laboratory tests with Urea Pre-dialysis 164.5 ± 38.9 mg / dL; hemoglobin 10.32 ± 1.9 g / dL; albumin 3.99 ± 0.4 g / dL; phosphorus 5.3 mg / dL; calcium 8.05 ± 0.9 mg / dL; parathyroid hormone 886 ± 747 pg / dL. Body composition BMI 23.6 kg / m2; R (Ω) 622.3; Xc (Ω) 48.4; and phase angle 4.3 °. 44% of the patients had mild malnutrition according to the Score Malnutrion Inflamation classification. The generic dimensions of the KDQOL-SF 36 revealed scores greater than 60 for CKD symptoms and effects, with an SF-12 Physical Health Composite 46.3 and SF-12 Mental Health Composite 56.3.

Conclusion

The costs of hemodialysis (HD) treatment are usually a huge financial burden for health systems and patients. HD sessions twice a week are common practice in many countries in patients without social security. Our results show that this therapy should not be categorized as a suboptimal therapy but as an option for patients with certain clinical characteristics.
