We aimed in this study to determine the opinion of the medical directors of dialysis centers in the Kingdom of Saudi Arabia (KSA) about the updates of strategies for evaluation and treatment of chronic kidney disease-mineral and bone Disorder (CKD-MBD). A questionnaire was sent to medical directors of 174 dialysis centers in the KSA between July and November 2009. The questionnaire was opinion based and comprised the prevalence of the CKD-MBD, strategies of therapy and indications of cinacalcet, a new therapy in the CKD patients. A total of 154 medical directors of the 174 (88.5%), who are the therapeutic decision-makers for 10100 (89%) dialysis patients, answered the questionnaire. There were 84 respondents (54%) who believed that the parathormone (PTH) blood levels initially increase at a glomerular filtration rate (GFR) < 30%. There were 80 (53%) respondents who believed that changes of phosphorus (PO4) and calcium (Ca) blood levels are initially observed at GFR < 30 mL/min. The majority of respondents, 115 (77%), 116 (80%), 95 (66%), and 134 (90%) currently have observed increased prevalence of vascular calcifications, adynamic bone disease, PTH > 500 pmol/L, and elevated Ca blood levels, respectively, only in the minority of advanced CKD. However, 88 (58%) respondents observed increased prevalence of elevated PO4 blood levels in the majority of new dialysis and advanced CKD patients. There were 137 (89%) respondents who believed from the current published evi-dence that CKD-MBD may result in increased morbidity (e.g. fractures) and mortality (e.g. cardiovascular) in advanced CKD and new dialysis patients. However, only 41 (27%) respondents follow the PTH levels in their patients every 2-3 months, while 81(53%) follow it every 6 months. There were 127 (83%), 129 (84%), 114 (75%) respondents who would start vitamin D (vit D) in dialysis and CKD patients for hypocalcemia, high PTH, and vit D 1,25 deficiency, respectively. However, only 51 (34%) respondents would start vit D therapy for vit D 25 deficiency. There were 98 (75%), 73 (57%) 74 (59%), and 88 (68%) respondents who claimed that they could achieve control of calcium levels alone, control of PO4 levels alone PTH levels alone , and all parameters of CKD-MBD in > 50% of their patients, respectively. There were 126 (82%) and 126 (82%) respondents who agreed to the indications of the cinacalcet that include refractory secondary hyperparathyroidism of dialysis patients to vit D and diet and phosphate binders together, and when surgical parathyroidectomy is contraindicated or fail in this population, respectively. However, 127 (83%) and 139 (91%) respondents disagreed to the indications that include indiscriminate prescription to all CKD patients or off label to some early CKD patients, respectively. We conclude that the medical directors of the active dialysis centers in Saudi Arabia are well aware of the morbidity and mortality caused by the CKD-MBD in addition to the indications of vit D and phosphate binders and cinacalcet therapy. However, the study suggests inadequate assessment of the prevalence, patterns of CKD-MBD, and results of intervention in the CKD patients such as treatment of vit D 25 deficiency, and knowledge of the availability of cinacalcet for the treatment of CKD-MBD. More local studies and guidelines are required to disseminate information about the current patterns of CKD-MBD for better approach to the management of this disorder in the kidney centers in this country.
在本研究中,我们旨在确定沙特阿拉伯王国(KSA)透析中心的医学主任对慢性肾脏病 - 矿物质和骨异常(CKD - MBD)评估和治疗策略更新的看法。2009年7月至11月期间,向KSA的174个透析中心的医学主任发送了一份问卷。该问卷基于观点,内容包括CKD - MBD的患病率、治疗策略以及西那卡塞(一种用于CKD患者的新疗法)的适应证。174名医学主任中的154名(88.5%)回复了问卷,他们是10100名(89%)透析患者的治疗决策者。84名(54%)受访者认为,甲状旁腺激素(PTH)血水平最初在肾小球滤过率(GFR)<30%时升高。80名(53%)受访者认为,磷(PO4)和钙(Ca)血水平的变化最初在GFR<30 mL/min时观察到。大多数受访者,即115名(77%)、116名(80%)、95名(66%)和134名(90%),目前仅在少数晚期CKD患者中观察到血管钙化、动力缺失性骨病、PTH>500 pmol/L和血钙水平升高的患病率增加。然而,88名(58%)受访者在大多数新透析和晚期CKD患者中观察到血磷水平升高的患病率增加。137名(89%)受访者根据当前已发表的证据认为,CKD - MBD可能导致晚期CKD和新透析患者的发病率(如骨折)和死亡率(如心血管疾病)增加。然而,只有41名(27%)受访者每2 - 3个月对其患者的PTH水平进行监测,而81名(53%)受访者每6个月进行一次监测。127名(83%)、129名(84%)、114名(75%)受访者分别会在透析和CKD患者中因低钙血症、高PTH和维生素D 1,25缺乏而开始使用维生素D(vit D)。然而,只有51名(34%)受访者会因维生素D 25缺乏而开始维生素D治疗。98名(75%)、73名(57%)、74名(59%)和88名(68%)受访者声称,他们分别能够在>50%的患者中单独控制钙水平、单独控制PO4水平、单独控制PTH水平以及控制CKD - MBD的所有参数。126名(82%)和126名(82%)受访者分别同意西那卡塞的适应证,即包括透析患者对维生素D、饮食和磷结合剂联合治疗难治性继发性甲状旁腺功能亢进,以及在该人群中手术甲状旁腺切除术禁忌或失败时使用。然而,127名(83%)和139名(91%)受访者分别不同意将其适应证包括对所有CKD患者无差别处方或对一些早期CKD患者超适应证用药。我们得出结论,沙特阿拉伯活跃透析中心的医学主任除了了解维生素D、磷结合剂和西那卡塞治疗的适应证外,还充分意识到CKD - MBD所导致的发病率和死亡率。然而,该研究表明,对CKD - MBD的患病率、模式以及CKD患者干预结果(如维生素D 25缺乏的治疗)的评估不足,并且对用于治疗CKD - MBD的西那卡塞的可获得性了解不足。需要更多的本地研究和指南来传播有关CKD - MBD当前模式的信息,以便在该国的肾脏中心更好地管理这种疾病。
