Our recent study

Our recent study ABT-888 supplier has proved that hepatitis C but not hepatitis B acts as a significant risk factor for proteinuria and CKD.38 It warrants more studies to investigate the association of hepatitis

C with morbidity and mortality of CKD. Third, family history of CKD/ESRD has been considered a significant risk factor for CKD.39–42 However, little is known about the role of family history of ESRD in the development of CKD in Taiwan. Our recent study demonstrated that higher prevalence of albuminuria and/or CKD existed not only in the first and second relatives of HD patients but also in the spouses of HD patients in comparison to their counterpart community controls.43 It suggests that both genetic susceptibility and environmental factors may interact and contribute to the development

of CKD in both genetic family members and non-genetic spouses of patients with ESRD. In sum, the above new findings have identified more potentially important risk factors for CKD. These results drive us to extend our screening program and care plan to these high-risk groups of CKD. The varied prevalence of CKD among different countries or in different Peptide 17 areas within the country must be interpreted with caution. These data could be influenced by many factors, such as the difference in survey design (random or purposed), study populations (general population or age-specific, or disease-specific), stages of CKD (all stages or stages of 3–5), method of creatinine measurement (Jaffe or enzymatic method and with or without standardization), equation formula for GFR calculation (Modification of Diet in Renal Disease (MDRD) or Cockcroft–Gault), and the ethnicities of different races. Calculation of GFR by four-variable MDRD equation is becoming more popular Fossariinae because of its simplicity. However, this equation has not been fully validated in Taiwanese subjects and in different stages of CKD. Over- or underestimation of GFR will cause incorrect diagnosis of CKD. It may delay intervention in subjects with true CKD or waste resources on subjects with normal renal function. Various modified equations of GFR calculations have been developed in Asian populations.9,10,17,24

A more accurate GFR equation for Taiwanese subjects by using inulin clearance as a standard reference is ongoing. More studies need to be validated before we can generalize this standard equation for eGFR to a wider population. The major impacts of CKD on public health in Taiwan are poor prognosis of high mortality and morbidity and the increased medical expenses. A large cohort study by Wen et al.13 has demonstrated that patients with CKD have 83% higher mortality for all-cause and 100% higher for cardiovascular diseases. Even for the subjects of CKD stage 1–2, hazard ratios (HR) for all-cause mortality were still significantly higher in those with overt proteinuria compared to those with negative proteinuria. As for the elderly population with CKD, Hwang et al.
