Serum zinc, selenium and copper in priest subjects.

OBJECTIVE: To study the serum zinc, selenium, and copper of priest subject who attended the outpatient Department, Priest Hospital Bangkok for a physical check-up, between March and October 2003 MATERIAL AND METHOD: The serum zinc, selenium, and copper of 112 priest subjects, 33 healthy and 79 diseased, compared with a control group of 90 males and 119females Thai volunteers. RESULTS: Serum copper was statistically significantly higher in the priest subjects than in the controls. However, serum selenium in the priest group was significantly lower than in the control group. Higher serum copper, zinc, and selenium levels were show in the male priest group than in the male control group. Of the priests subjects 50.9% (56/110) and 16.5% (18/109) had decreased zinc and selenium levels respectively. The controls had decreased zinc level at 53.4% (39/73) in males, and 34.3% (36/105) in females, and decreased selenium level at 18.6% (35/188). Serum copper concentrations were greater than 140 mg/dl in 44.5% of priest and 30% control subjects. CONCLUSION: Statistically significant difference in serum selenium and copper found in the priest subject when compared with the control subject.

HLa-class II (DRB & DQB1) in Thai sudden unexplained death syndrome (Thai SUDS) families (Lai-Tai families).

Thai Sudden Unexplained Death Syndrome (Thai SUDS), or Lai-Tai, is a major health problem among rural residents of northeastern Thailand. The cause has been identified as a genetic disease. SUDS, a disorder found in Southeast Asia, is characterized by an abnormal electrocardiogram with ST-segment elevation in leads V1-V3, identical to that seen in Brugada Syndrome (Brugada Sign, BS) and sudden death due to ventricular fibrillation and cardiac arrest (represents an arrhythmogenic marker that identifies high-risk for SUDS). SUDS victims have a sleeping disorder (narcolepsy). The HLA-DR locus is tightly associated with narcoleptic Japanese patients and HLA-DR2, DQ haplotypes were also found in Oriental narcoleptic patients. These circumstances prompted us to study the association between the disease and HLA Class II by HLA DNA typing using a PCR-SSO method, with five Thai SUDS families (18 BS-positive subjects as the cases, and 27 BS-negatives as the controls). We found that the HLA-DRB1 *12021 allele was significantly increased in BS-positive subjects (p = 0.02; OR = 4.5), the same as the HLA-DRB1*12021-DQB1 *0301/09 haplotype (p = 0.01; OR = 7.95). Our data suggests that the HLA-DRB1* 12021 allele associated with BS and the HLA-DRB1*12021-DQB1 *0301/09 is a haplotype susceptible to arrhythmogenic markers that can identify a high risk for SUDS.

Relationship between serum antioxidant vitamins A, E, and C and lipid profiles in priest subjects at the Priest Hospital.

The serum vitamins A, E, and C (antioxidant vitamins) of 112 priest subjects, compared with 90 males and 119 females in a control group, were investigated. Subjects for the study were Thai volunteers who attended the Outpatient Department, Priest Hospital, Bangkok, for a physical check-up from July to September 2003. There was no age difference between the priest group and the controls. All serum vitamins, A, E, and C, of the priest group were significantly lower than the control group. Statistically significantly higher levels of total cholesterol, LDL-C, and LDL-C/HDL-C ratio were found in the priest subjects compared with the controls. The median serum retinol concentration in the priest subjects was 3.02 micromol/l (range 1.47-4.01 micromol/l) compared with 3.23 micromol/l (range 1.74-4.57 micromol/l) in the controls (p<0.01). The median serum a-tocopherol concentration in the priest subjects was 18.1 mmol/l (range 5.8-27.3 micromol/l) compared with 19.6 mmol/l (range 7.3-37.7 micromol/l) in the controls (p<0.01). The median serum ascorbic acid concentration in the priest subjects was 3.74 mg/l (range 0.0-17.0 mg/l) compared with 6.37 mg/l (range 0.0-18.0 mg/l) in the controls. The median values for retinol, alpha-tocopherol, and ascorbic acid serum concentrations in the male priests were lower than the control males. A total of 28% and 65% of the priest subjects had decreased alpha-tocopherol and ascorbic acid levels, while the controls had decreased alpha-tocopherol and ascorbic acid levels of 20% and 31.5%, respectively. A total of 67.8% and 54.4% of priest and control subjects, respectively, had cholesterol concentrations of > or = 5.18 mmol/l. However, a prevalence of low HDL-C (HDL-C < or = 0.91 micromol/l) was found in 1.8% of priest subjects and 1.4% of controls. Statistically significant associations were found between alpha-tocopherol, cholesterol, LDL-C, triglyceride, and serum retinol. A positive correlation was found between age, retinol, and serum alpha-tocopherol. A negative correlation was found between cholesterol, HDL-C, LDL-C, and the serum alpha-tocopherol/cholesterol ratio. In addition, negative correlations were found between weight, cholesterol, LDL-C, triglyceride, and the serum alpha-tocopherol/(cholesterol + triglyceride) ratio in priest and control subjects. The results suggest more research should be conducted into the health and nutritional problems of both healthy and diseased priest subjects concerning vitamins and oxidative stress.

Serum copper, zinc, ceruloplasmin and superoxide dismutase in Thai overweight and obese.

The serum copper, selenium, ceruloplasmin, superoxide dismutase (SOD) (specific activities of antioxidant enzymes), anthropometric measurements, including waist/hip ratio 51 male and 190 female overweight subjects (body mass index (BMI) > or = 25.0 kg/m2) compared with a 26 male and 83 female control group (BMI = 18.5-24.9 kg/m2) Thai volunteers who attended the Out-patient Department, General Practice Section, Rajvithi Hospital, Bangkok, for a physical check-up from March to October, 1998, were investigated. There was no age difference between the overweight group and the controls. All of the anthropometric variables, except the height of the overweight group, were significantly higher than those of the normal subjects. The medians of weight and waist/hip ratio of overweight and obese males were significantly higher than those of overweight and obese females. Serum ceruloplasmin, copper were statistically significantly higher in overweight subjects than in the controls. However, serum zinc and superoxide dismutase activity in the overweight group were found to be lower than in the control group. Higher serum ceruloplasmin, copper, zinc and superoxide dismutase activity were shown in the female overweight group than in the male overweight group. Ceruloplasmin was found to correlate positively with copper concentration but negatively related with superoxide dismutase enzyme activity. A negative correlation was found between serum copper and zinc concentrations in both sexes of the overweight and obese subjects. Low SOD activity found in the overweight and obese subjects might be caused by low zinc intake.
