| Outline of Final Research Achievements |
Glomerular filtration rate (GFR) estimating equations are generally used for assessment of kidney function that is important for diagnosis of kidney disease. GFR equations based on serum creatinine and cystatin C developed from Japanese subjects are commonly used in Japan. But, it is not clear that the GFR equations for Japanese subjects could be used in other Asian populations. Therefore, we studied with Taiwan, Korea, Thai and India researchers and collected 273, 277, 28 and 130 measured GFR data, respectively. We analyzed the accuracy of the Japanese GFR equations in these Asian populations. Performance of the GFR equation based on serum creatinine varied according to race. The equation underestimated and overestimated GFR in Taiwan and Indian subjects, respectively. On the other hand, the GFR equation based on serum cystatin C showed better performance and acceptable accuracy in the Asian populations. It could be used as a single common GFR equation fit for Asians.
