Abstract Background: The aim of this study was to investigate vitamin D receptor (VDR) gene polymorphism as a risk factor associated with chronic periodontitis (CP) and to determine the effect of VDR gene polymorphism on phenotypic CP.Methods: This study is a case-control design that included 162 adults divided into two groups: patients with CP (case group) and patients without CP (control group). Venous blood and DNA were obtained from individual samples. The gene polymorphism was determined using Restricted Fragment Length Polymorphism-Polymerase Chain Reaction (RFLP-PCR) and DNA sequencing to identify endonuclease restrictions in exon 9 (TaqI). The data were analyzed using an independent t-test and Fisher’s exact test. The odds ratio (OR) was used to calculate the risk of VDR gene polymorphism in CP. Results: VDR gene polymorphism was detected in patients with CP and a TT genotype (86.4%), Tt genotype (12.4%), and tt genotype (1.2%). The case group with TT and Tt genotypes had an OR of 12.5 (95% CI:1.6–99.8) of having CP compared to the control group (P<0.05).Conclusions: VDR gene polymorphisms (the TT and Tt genotypes) are risk factors associated with individual susceptibility to CP.

Objective. To determine the phenotypic manifestations of essential arterial hypertension (EAH) according to the vitamin D receptor gene polymorphism (VDR rs10735810, rs2228570).Material and methods. The case-control study involved 100 patients with EAH stage II, 1-3 degrees of blood pressure (BP), high and very high cardiovascular risk, 21% (21) men, 79% (79) women. The mean age of patients was 59.86 ± 6.22 y.o. The control group consisted of 60 healthy individuals, comparable in age and gender. To study the VDR gene polymorphism (rs10735810, rs2228570) performed a qualitative polymerase chain reaction in real-time. Results. Almost half of the patients with elevated normal BP (44.4%) and 34% of patients with EAH 2-3 d. there is concomitant diabetes mellitus (DM) type 2, while for EAH 1 d. it is only 19%. Obesity of 1-3 degrees was shown in 53% of patients with EAH: average EAH of 1 d. - 21%, among the EAH 2-3 d. - 25%. In the control group, 16% suffered from obesity. The distribution of VDR gene polymorphism genotypes according to the presence of DM showed that it was present in 35% of patients with AA-genotype, which is 1.6 times more often than in patients with GG-genotype (22%). Most smokers among patients with GG-genotype (26%), which is twice as common as those with AA- and AG-genotype (13% and 14%, respectively). Obesity of 1-3 degrees most often met among carriers of GG-genotype - 74%, and in the control group 14%. An elevated level of waist-hip ratio (WHR) among women with EAH was in 80% of the AA-genotype carriers, in the control group, all women had normal values. In 76% of the AG-genotype carriers and in 81% of the GG-genotype carriers, the WHR was increased by 2.3 and 2.8 times, respectively, that in the control group. Deviations of systolic and diastolic BP according to the VDR gene polymorphic variants have not been established.Conclusions. The AA-genotype is associated with DM 2 and with elevated WHR in women; GG-genotype - with elevated BMI, especially in men.

Background Vitamin D deficiency and vitamin D receptor (VDR) gene polymorphisms are strongly associated with tuberculosis (TB) susceptibility in countries with four seasons. As a country with sufficient sunlight for vitamin D production in skin, the incidence of TB in Indonesia remains high. Objective To assess for possible associations between the incidence of tuberculosis and serum vitamin D level, as well as VDR FokI polymorphisms in children. Methods A case-control study was conducted at the Department of Child Health, Dr. Mohammad Hoesin Hospital, Palembang from November 2011 to April 2012. Subjects were children with TB (the case) and children without TB who had been exposed to TB in the home (the control). Serum vitamin D [1,25(OH)2D3 or calcitriol] level was measured by immunodiagnostic system (IDS) 1,25-dihydroxy vitamin D enzyme immunoassay (EIA) kit. The VDR FokI polymorphisms were identified by polymerase chain reaction (PCR) and restriction-fragment length polymorphism (RFLP) analysis. Results Sixty subjects was divided equally into the case and control groups. The mean serum calcitriol level in the case group was significantly lower than that of the control group [105.5 (SD 66.9) pmol/L vs. 162.9 (SD 52.9) pmol/L, respectively; (P=0.001)]. We found 9 subjects with calcitriol deficiency, 8 in the TB group and 1 in the healthy contact group (OR 10.5; 95%CI 1.2 to 90.7) The VDR FokI polymorphism was seen in 28 subjects in the case group and 22 in the control group (OR 5.0; 95%CI 0.9 to 26.4). Conclusion Vitamin D (calcitriol) deficiency and lower serum levels are associated with higher risk of TB in children. The VDR gene FokI polymorphism also contributes to susceptibility for TB.

AIM:: Knowing distribution frequency of genotype and allele Vitamin D receptor (VDR) gene polymorphism FokI rs2228570, ApaI rs797523, and TaqI rs731236 in leprosy patients. METHODS: This is an observational research that was done in Leprosy Division, Department of Dermatology and Venereology, Haji Adam Malik General Hospital, Dr. Pirngadi General Hospital in Medan, and other primary healthcare facilities in North Sumatera. The research subjects underwent an interview process, physical examination and blood collection to detect VDR gene polymorphism FokI rs2228570, ApaI rs797523, and TaqI rs731236. The data were then tabulated and analyzed, also calculated using Hardy-Weinberg equilibrium. RESULTS: This study involved 52 leprosy patients, with most of them aged between 35 and 44 years (38.5%), male (61.5%) more than female (38.5%). The research subjects have VDR gene polymorphisms FokI rs2228570 with genotype FF (42.3%) with F allele (59.6%), ApaI rs797523 genotype AA (46.1%) with A allele (65.4%) and TaqI rs731236 genotype TT (86.5%) with T allele (93.3%). CONCLUSION: Most of the leprosy patients have genotype FF with F allele, genotype AA with A allele and TT with T allele. Further research can be done to assess the relationship between the VDR gene polymorphism and leprosy risk.
