PD匯報 2011-10-26
比誰老得快? 台灣勇奪世界冠軍 • 國內婦女生育率屢創新低,今年一到八月出生人數只有十萬九千一百四十一人,再度改寫歷史新低紀綠。 • 內政部昨天公布全台百歲以上人瑞,共計一千三百九十九人,人數創下歷史新高。 • 經建會援引聯合國最新資料,加入台灣數據分析後發現,台灣是全球「老得最快」的國家,預計在二○五○年趕上日本,並列為全球最老的兩個國家。 • 經建會預測,最快四年後全國會有一半以上的人口超過四十歲,十五年後進入老年人口占總人口比率超過百分之二十的「超高齡社會」,五十年後,有一半的人超過六十歲。 聯合報 2010.10.10
台灣的老人化事實 • 在二○五○年,日本與台灣的老年人口(六十五歲以上)占總人口比率,都將高達百分之三十八,並列全球最老的兩個國家。但日本花了六十年時間才達到,台灣可能只花四十年時間就「達陣」。 • 經建會預測,目前平均每六名青壯年(廿五到六十四歲的勞動力)扶養一名老年人;廿年後,將快速攀高為平均每兩個青壯年扶養一名老年人,五十年後,會變成每一名青壯年扶養一名老年人。 聯合報 2010.10.10

Which modality is better to prolong the dialysis patient survival? Periteonal dialysis (PD) Hemodialysis (HD) There is always a debate No meta-analysis evidence Heterogeneity in the patients’ background

Age and DM accounts for the most patients on dialysis in USA: 398,940 patients in1995-2000 Age>65: total: 51%; HD: 53%; PD: 36% DM: total: 45%; HD: 44%; PD: 45% Vonesh et al. Kidney Int, 2004
Three important factors interacts with treatment modality • Age > 65 years old • DM • Comorbidity: 占50%透析病人死亡原因 • 冠狀動脈疾病 • 鬱血性心衰竭
Improved outcome in 1998-2000 vs 1995-1997 (USA) 1.04 Vonesh et al. Kidney Int, 2004
The real difference in life expectancy • Adjust median life expectancy • HD: 35.1 months • PD: 33.8 months Vonesh et al. Kidney Int, 2004
Age is an important factor of mortality 年齡大於65歲 You cannot do anything to change the fact.
Diabetes mellitus is an important factor of mortality DM is an essential factor for the survival of dialysis patients in western countries.

心血管疾病是一個透析病人死亡的重要原因 透析病人心血管疾病死亡率比一般人心血管疾病死亡率高10~30倍 心血管疾病的原因: Vascular remodeling Vascular calcification
Vascular remodeling • Increased tensile stress • Prevention • Intravascular volume control: Interdialytic body weight gain < 5% increase • Adequate blood pressure control
Vascular calcification的原因 Nolan et al. J Am Soc Nephrol, 2010
Vascular calcification的結果 • Myocardia ischemia: acute myocardia infarction and angina pectoris • Congestive heart failure • Cardiac valve insufficiency • Cardiac arrhythmia • Ischemia of peripheral vessels
Prevention of vascular calcification: Adequate dialysis • Prescribed dose: Kt/V > 1.3 and delivered dose Kt/V > 1.2 in hemodialysis patients • For CAPD, the delivered PD dose should be a total Kt/Vurea of at least 2.0 per week and a total creatinine clearance (CCr) of at least 60 L/wk/1.73 m2 for high and high-average transporters, and 50 L/wk/1.73 m2 in low and low-average transporters. K-DOQI guideline, 2002
Prevention of vascular calcification: Bone-mineral disease • Control of hyperparathyroidism: iPTH 150 ~ 300 pg/mL • CaxP < 55 • Corrected Ca: 8.8~9.5 mg/dL • Taking Ca-based phosphate binders < 10.2 mg/dL • P: 3.5~5.5 mg/dL K-DOQI guideline, 2002
Brief summary • PD with equivalent or better survival among non-DM patients • In DM patients, younger patients may benefit from PD (age<45y/o in USA; equally in in Canada and Denmark) • PD has an equal or lower mortality rate during the first 1-2 years. • A temporal trend of improved outcome in PD that exceeds HD. • Age, DM and co-morbidity(conary artery disease and congestive heart failure) are important factors.
