Prevalence Pattern of Key Polymorphisms in the Vitamin D Receptor gene among Patients of Type 2 Diabetes Mellitus in Northeast India.

ABSTRACT:

Aims

To investigate the association between Vitamin D receptor gene polymorphisms (BsmI, TaqI and FokI) and type 2 diabetes mellitus in patients in north eastern India.

Settings and design

This was a case control study with 40 cases of type 2 diabetes and 20 controls.

Materials and methods

Genomic DNA was extracted from blood and genotyped for the single nucleotide polymorphism (SNPs) of BsmI [rs1544410], TaqI [rs731236] and FokI [rs2228570] by polymerase chain reaction and gene sequencing. Genotype distribution and allelic frequencies were compared between patients and controls. Data was expressed as mean ±standard deviation. Chi square test and t test were used to compare groups. Statistical analysis was done using SAS version 9.3 software. P value of <0.05 was considered significant.

Results

Body weight and BMI were significantly associated with VDR polymorphisms BsmI and TaqI while BsmI was significantly associated with HbA1C. Vitamin D deficiency was significantly greater in cases than controls. The frequency of the heterozygous genotype of the BsmI polymorphism was significantly greater in type 2 diabetics than in controls.

Conclusions

Vitamin D receptor polymorphisms are associated with type 2 diabetes in our population and require larger scale studies to be considered as possible risk factors or type 2 diabetes mellitus.

Project description:BACKGROUND:The incidence of type 1 diabetes mellitus (T1DM) in Kuwait is amongst the highest in the world. Vitamin D is considered to be involved in immune modulation and its deficiency contribute to autoimmune destruction of insulin producing beta cells in T1DM patients. Vitamin D has been shown to exert its effects via a nuclear vitamin D receptor (VDR) and therefore, VDR gene may be considered a candidate for T1DM susceptibility. METHODS:The genotypes of four VDR gene polymorphisms were determined in 253 Kuwaiti Arab T1DM patients and 214 healthy controls by PCR-RFLP analysis. Serum concentrations of three autoantibodies i.e. ICA (Islet cell autoantibody), GADA (Glutamic acid decarboxylase) and INS (Insulin autoantibody) were determined by radio-immunoassays. RESULTS:Statistically significant differences were detected between the genotypes of two VDR gene polymorphisms (FokI, C?>?T, rs10735810 and TaqI, C?>?T, rs731236) between T1DM patients and controls (P?<?0.0001). In both, the frequency of variant alleles was considerably high in T1DM than in the controls. In contrast, the VDR gene ApaI (G?>?T, rs7975232) and BsmI (A?>?G, rs1544410) polymorphisms did not show association with T1DM. The homozygous variant genotypes of FokI, ApaI and TaqI polymorphisms show significant differences between various age-of-onset subgroups while no such association was detected in the case of BsmI polymorphism. Significant differences were also noted between heterozygous genotypes of all four polymorphisms especially between 4-6y and?>?6y age-of-onset subgroups of T1DM patients. Three autoantibodies, ICA (Islet cell), GADA (glutamate decarboxylase) and INS (insulin) were positively associated to, varying degrees, with T1DM in Kuwaiti Arabs harboring different VDR gene polymorphism genotypes. CONCLUSIONS:Our results demonstrate a significant effect of two VDR gene polymorphisms (FokI and TaqI) and three autoantibodies on genetic susceptibility of T1DM in Kuwaiti Arabs along with other factors.

Project description:BackgroundCardiovascular disease is the most prevalent cause of morbidity and mortality in diabetic patients. Hypertension (HTN) has been confirmed as a major risk factor for cardiovascular disease, which is frequently associated with diabetes mellitus (DM). Therefore, the detection and management of elevated blood pressure (BP) is a critical component of the comprehensive clinical management of diabetics. Since the rates of hypertension in diabetics are lacking in Afghanistan, this study aimed to evaluate the prevalence of elevated blood pressure in type-2 diabetic patients.Materials and methodsThis is a descriptive cross-sectional study, which included 321 type -2 diabetic patients (119 males, 202 females) with a mean age of 53.86 ± 11.54 years who were presented to the Noble OPD center from November 2019 to January 2020.ResultsThe elevated blood pressure was detected in 70.5% of the patients. It was more prevalent in women than men (76.8% and 59.7% respectively). The mean systolic blood pressure was 146.94 ± 23.19 mmHg and mean diastolic blood pressure was 89.61 ± 11.59 mmHg. The mean pulse pressure was 57.32 ± 15.58 mmHg and the mean arterial pressure was 48.98 ± 7.73 mmHg. The mean body weight was 73.09 ± 13.75 Kg. The mean duration of diabetes mellitus was 7.08 ± 5.95 years with the average HbA1c of 9.27 ± 2.41%. The mean body mass index (BMI) of the patients was noted 28.77 ± 5.58 kg/m2.ConclusionThis study showed high prevalence of hypertension in type-2 diabetes patients with a significant difference in the rate of elevated blood pressure between males and females (it was higher in females than males). The systolic blood pressure had a positive correlation with age. However, it was insignificant for diastolic blood pressure. Healthcare providers and other health sector should work in collaboration for designing appropriate preventive strategies targeting the modifiable risk factors associated with hypertension.
