BACKGROUND: Metabolic syndrome (Met-S) that caused by heredity and Lipoprotein Lipase (LPL). LPL is involved in the metabolism of serum lipids. Variations in LPL alter enzyme activity, and the most common variations are LPL +495 T > G and LPL Pvu II C > T. AIM: This study aimed to identify the role of LPL +495 T > G and LPL PvuII C > T gene variations in subjects with Met-S in Javanese ethnic based on age stratification. METHODS: We recruited 160 participants of Javanese ethnicity consisting of 80 cases and 80 control subjects. Met-S was diagnosed according to the criteria of NCEP ATP III. Peripheral blood samples were collected to determine biochemical parameters. Screening for both polymorphisms was made by PCR-RFLP. RESULTS: Results found that genotype and allele frequencies for LPL +495 T > G were not significantly different between Met-S and controls with and without age stratification. In LPL PvuII C > T based on age stratification, there were significant differences between TT vs CC, recessive and dominant models in Met-S and control. In the age group > 45 years CC genotypes and TC+CC had increased risk of Met-S compared to TT genotypes. In summary, there was no significant association between LPL +495 T > G gene variation with Met-S. CONCLUSION: In LPL PvuII gene variation, TC + CC is the risk genotype of Met-S in the age group > 45 years.

The prevalence of metabolic syndrome (MetS) is high worldwide which it can increase the risk of some diseases such as cardiovascular disease, type 2 diabetes mellitus even mortality. The prevalence pattern and determinants of MetS risk factors might differ among ethnics in Indonesia. This study aimed to determine the anthropometry and metabolic measurements determinants to predict the MetS prevalence of the Javanese population in Yogyakarta. It was a case control study conducted from December 2018 to March 2019 involving 214 Javanese subjects aged 20-74 years resided in Yogyakarta Special Region, Indonesia. NCEP ATP III criteria were used to identify MetS as case and not diagnosed with MetS as control. The results showed that BMI, WC, BP, total cholesterol and HDL-C were significantly different between MetS and non MetS patients (p<0.005). In MetS subjects, prevalence of obesity was 75.3%, visceral fat was 75.3%, WC 92.95%, WHtR 97.64% and total cholesterol/HDL-C ratio 553%, which independently increased the risk of MetS 7. 30, 5.32, 13.37, 20.75, and 7.16 times, respectively. Result of logistic regression analysis showed central obesity based on WC increased the risk of Met-S by 17.62 time and the ratio of total cholesterol/HDL-C>5 by 9.54 time. In conclusion, WHtR is a better marker for MetS prediction independently. However, the WHtR in combination with WC and total cholesterol/HDL-C ratio are better for MetS prediction in the Javanese population.

Background The genetic variation of nicotinamide phosphoribosyl transferase (NAMPT) gene rs4730153 is reported to be associated with cardiometabolic risk, but the results are inconsistent between populations. Ethnicity, metabolic risk and lifestyle play a role in the association of the genetic variant and the metabolic syndrome (MetS). To the best of our knowledge, no research has yet been published concerning the Javanese population, so this study aimed to investigate the association of rs4730153 with MetS and its interaction with metabolic risk and lifestyle. Results The GG genotype (p = 0.031; OR 95% CI 3.88 [1.13–13.33]), GA+GG genotype (p = 0.048; OR 95% CI 10.52 [1.02–108.01]) and G allele carrier (p = 0.006; OR 95% CI 4.19 [1.51–11.64]) of rs4730153 had a higher risk of the MetS after adjusting for obesity, hypercholesterolemia, smoking and food intake. The risk was statistically significant for the younger age group ≤ 45 years old. Conclusion The GG, GA+GG genotype and G allele carrier of rs4730153 have a higher risk of the MetS, especially those who are obese, hypercholesterolemic and smokers and have a higher food intake in those aged ≤ 45 years old. Further larger, multicentre studies are required to confirm these pilot results.
