BACKGROUND
Online hemodiafiltration (OL-HDF) offers considerable advantages in clearance of molecules of various sizes. However, evidence of clinical effects of OL-HDF is scarce in Korea. In this study, we investigated changes in laboratory values over more than 12 months after switching to OL-HDF.
METHODS
Adult patients with end-stage renal disease undergoing hemodialysis (HD) were prospectively enrolled in a K-cohort (CRIS no. KCT0003281) from 6 tertiary hospitals in South Korea. We recruited 435 patients, 339 of whom were on HD at enrollment. One hundred eighty-two patients were followed for more than 24 months. Among them, 44 were switched to OL-HDF for more than 12 months without conversion to HD. We used a paired test to compare baseline and 24-month follow-up results.
RESULTS
The mean age of the subjects was 61.2 ± 12.2 years, and 62.6% were male. The baseline hemoglobin level was not significantly different between HD and OL-HDF group (10.61 ± 1.15 vs. 10.46 ± 1.03 g/dL, = 0.437). However, the baseline serum protein and albumin levels were significantly lower in the OL-HDF group (6.82 ± 0.49 vs. 6.59 ± 0.48 g/dL, = 0.006; 3.93 ± 0.28 vs. 3.73 ± 0.29 g/dL, < 0.001). In patients switched to OL-HDF, levels of hemoglobin and serum albumin significantly increased (10.46 ± 1.03 vs. 11.08 ± 0.82 g/dL, = 0.001; 3.73 ± 0.29 vs. 3.87 ± 0.30 g/dL, = 0.001). The normalized protein catabolic rate decreased after 24 months, but the change was not significant (1.07 ± 0.25 vs. 1.03 ± 0.21 g/kg/day, = 0.433). Although the dose of erythropoiesis-stimulating agent was lower in patients who converted to HDF, it was not significantly different (-115.7 ± 189.7 vs. -170.5 ± 257.1 = 0.206).
CONCLUSION
OL-HDF treatment over more than 12 months was associated with no harmful effects on anemia and nutritional status.
背景
联机血液透析滤过（OL-HDF）在清除各种大小分子方面具有显著优势。然而，在韩国，OL-HDF临床效果的证据很少。在本研究中，我们调查了转换为OL-HDF超过12个月后实验室指标的变化。
方法
来自韩国6家三级医院的终末期肾病接受血液透析（HD）的成年患者被前瞻性纳入一个韩国队列（CRIS编号KCT0003281）。我们招募了435例患者，其中339例在入组时接受HD治疗。182例患者随访超过24个月。其中，44例转换为OL-HDF超过12个月且未转换回HD治疗。我们使用配对检验比较基线和24个月随访结果。
结果
受试者的平均年龄为61.2±12.2岁，男性占62.6%。HD组和OL-HDF组的基线血红蛋白水平无显著差异（10.61±1.15 vs. 10.46±1.03 g/dL，P = 0.437）。然而，OL-HDF组的基线血清蛋白和白蛋白水平显著更低（6.82±0.49 vs. 6.59±0.48 g/dL，P = 0.006；3.93±0.28 vs. 3.73±0.29 g/dL，P<0.001）。转换为OL-HDF的患者中，血红蛋白和血清白蛋白水平显著升高（10.46±1.03 vs. 11.08±0.82 g/dL，P = 0.001；3.73±0.29 vs. 3.87±0.30 g/dL，P = 0.001）。24个月后标准化蛋白分解代谢率下降，但变化不显著（1.07±0.25 vs. 1.03±0.21 g/kg/天，P = 0.433）。虽然转换为HDF治疗的患者促红细胞生成素剂量更低，但差异不显著（-115.7±189.7 vs. -170.5±257.1，P = 0.206）。
结论
超过12个月的OL-HDF治疗对贫血和营养状况无有害影响。
