摘 要 目的:探討給予尿毒癥難治性高血壓(uremia refractory hypertension, URH)患者維持性血液透析(maintenance hemodialysis, MHD)、血液透析濾過(hemodiafiltration, HDF)治療的臨床效果。方法:選取66例URH患者隨機分為對照組和觀察組各33例,對照組給予MHD治療,觀察組給予MHD+HDF治療,觀察兩組血壓及其他實驗室檢驗指標(biāo)改善情況。結(jié)果:透析后,觀察組患者血壓水平及血甲狀旁腺素(parathyroid hormone, PTH)、血清b2微球蛋白(b2-microglobuin, b2-MG)、血漿腎素(plasma renin, RA)、血管緊張素Ⅱ(angiotensin II, Ang II)濃度均顯著低于對照組(P<0.05);觀察組治療總有效率為93.94%,顯著高于對照組的72.73%(P<0.05)。結(jié)論:給予URH患者MHD聯(lián)合HDF治療,可有效提高血PTH、血b2-MG及RA、Ang II清除效果,使患者血壓水平獲得更大程度改善,提高總療效。

ABSTRACT Objective: To evaluate the clinical effect of maintenance hemodialysis (MHD) and hemodiafiltration (HDF) in patients with uremic refractory hypertension (URH). Methods: Sixty-six patients with URH were randomly divided into a control group and an observation group with 33 cases each. The control group was treated with MHD while the observation group was treated with MHD + HDF. The improvement of blood pressure and other laboratory test indicators in the two groups was observed. Results: After dialysis, the levels of blood pressure, plasma parathyroid hormone (PTH), serum b2 microglobulin(b2-microglobulin, b2-MG), plasma renin (RA), angiotensin II (AngII) were significantly lower and the total effective rate was significantly higher (93.94% vs 72.73%) in the observation group than the control group (P<0.05). Conclusion: MHD combined with HDF in URH patients can effectively improve the clearance effect of PTH, b2-MG, RA and Ang II in blood, the blood pressure level in patients with URH and the overall curative effect.

尿毒癥難治性高血壓(uremia refractory hypertension, URH)屬于臨床上治療難度較大的病癥,指的是尿毒癥患者接受血液透析、超濾脫水治療之后,能夠達到干體重,聯(lián)合使用≥3聯(lián)足量降壓藥物進行治療后,持續(xù)性高血壓仍存在[1]。在尿毒癥高血壓患者中,URH的發(fā)病率占5%~10%左右。機體長期處于高血壓狀態(tài)可導(dǎo)致 URH患者出現(xiàn)一系列心腦血管并發(fā)癥,嚴(yán)重影響患者健康狀況,如未能及時接受有效治療甚至可威脅生命安全。目前,臨床上主要選用維持性血液透析(maintenance hemodialysis, MHD)給予URH患者治療,但既往研究顯示,該種療法無法將患者體內(nèi)毒素完全清除,總體療效存在明顯局限性[2]。血液透析濾過(hemodiafiltration, HDF)能夠更好地將存在于患者體內(nèi)中、大分子毒素等多種有害物質(zhì)有效清除,有助于患者機體高血壓狀態(tài)改善[3]。本研究主要探討MHD、HDF同時用于URH患者治療的臨床效果,旨在探討URH更有效的治療方案。
