The prevalence of metabolic syndrome in Japanese renal transplant recipients.

BACKGROUND

The prevalence of metabolic syndrome (MS) after renal transplantation has yet to be elucidated. In the present study, we investigated the prevalence of MS in Japanese renal transplant recipients.

METHODS

A cross-sectional study was conducted to determine the prevalence of MS in 101 renal transplant recipients at Osaka City University Hospital. The prevalence of MS was determined using the National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATPIII) criteria (modified and original) and the International Diabetes Federation (IDF) criteria.

RESULTS

Using the modified (Japanese) NCEP criteria, a total of 24 out of 101 patients (23.8%) had MS including 21 out of 64 male patients (32.8%) and three out of 37 female patients (8.1%). Using the modified (Asian) NCEP criteria, MS was diagnosed in 23 patients (22.8%); 19 male (29.7%) and four female (10.8%). Using the original NCEP criteria, MS was diagnosed in 15 patients (14.9%); 12 male (18.8%) and three female (8.1%). Using the IDF criteria, MS was diagnosed in 16 patients (15.8%); 15 male (23.4%) and one female (2.7%).

CONCLUSION

The prevalence of MS differed according to the NCEP criteria used, which had different cut-off points for waist circumference (14.9-23.8%). By the IDF criteria, which cites central obesity as an essential component, the prevalence of MS was slightly lower. Furthermore, in our study, MS was more prevalent in male renal transplant recipients.
