BACKGROUND: Residual cardiovascular risk factors, such as triglyceride (TG), can cause cardiovascular disease. The role of TG metabolism in kidney transplantation remains unclear. METHODS: Sixty-three consecutive stable recipients at 1 year after their kidney transplants were included in the study from January to September 2014 at Nagoya Daini Red Cross Hospital. We performed the cookie test to evaluate TG metabolism. TG, blood sugar, and remnant-like particle cholesterol (RLP-C) were measured at fasting (f) and 2 and 4 h after ingestion. Low- and high-density lipoprotein cholesterol (LDL-C and HDL-C, respectively) and apoB levels were measured at fasting. RESULTS: Mean TGf and RLP-Cf were 139.4 ± 62.6 and 5.6 ± 3.4 mg/dl, respectively, and were within normal ranges; however, both mean TG 2 and 4 h were >200 mg/dl, and both mean RLP-C 2 and 4 h were >9 mg/dl. A negative correlation was seen between TGf and eGFR (r = -0.48, p < 0.001). TGf positively correlated with RLP-C, non-HDL-C, LDL-C/apoB ratio, and body mass index (r = 0.80, p < 0.001; r = 0.47, p < 0.001; r = 0.48, p < 0.001; and r = 0.38, p = 0.002, respectively). LDL-C levels were controlled because of the use of statin, but LDL-C/apoB ratio levels in 50% of the recipients were <1.2, indicating that the rate of small dense LDL-C in LDL-C had increased. CONCLUSION: The prevalence of postprandial hypertriglyceridemia among kidney transplant recipients was high; however, the question of whether or not it should be treated remains unknown.
