Background The prevalence of kidney stones in the world is increasing and environmental factors seem to play a major role in this issue. The aim of the present study was to investigate the prevalence of risk factors of kidney stones in the adult population of Rafsanjan city based on the data of the Rafsanjan Cohort Study (RCS). Methods In the baseline phase of this study, 10,000 people aged 35 to 70 years are enrolled in the RCS, as one of the prospective epidemiological research studies in Iran. From this population, 9932 participants completed related demographic questionnaires as well as reported a history of diabetes mellitus, kidney stone, and hypertension diseases. The obtained data were analyzed using univariable and multivariable logistics regression. Results According to the obtained results, 46.54% of the studied population were male and 53.46% were female. The mean age of the participants was 49.94 ± 9.56 years. 2392 people accounting for 24.08% of the population had kidney stones. After adjustment of the variables, six variables of gender, WSI, no consumption of purified water, BMI, and history of hypertension and diabetes were found to be significant related factors of kidney stone disease. Conclusions Gender, hypertension, obesity, diabetes, and personal habits like alcohol consumption, opium use and, cigarette smoking are effective in the development of kidney stones. So, by identifying the susceptible patients and teaching them, the burden of the disease on society and the individual can be reduced. The results of this study are helpful to health care providers for preventive planning for kidney stone disease.
Background We evaluated the relation between ALT, AST, GGT and ALP with diabetes in the Rafsanjan Cohort Study. Materials and methods The present study is a cross-sectional research including 9991 adults participated via sampling. We used data obtained from the Rafsanjan Cohort Study (RCS), as a part of the prospective epidemiological research studies in IrAN (PERSIAN). Elevated serum levels of ALT, AST, GGT and ALP were defined according to the reference range of the laboratory in the cohort center. Serum liver enzymes levels within the normal range were categorized into quartiles, and their relationship with diabetes was evaluated by logistic regressions. Findings In present study, elevated serum levels of ALT, AST, GGT, and ALP were associated with increased odds of diabetes (adjusted ORs: 1.81, 95%CI 1.51–2.17; 1.75, 95%CI 1.32–2.32; 1.77, 95%CI 1.50–2.08; 1.60, 95%CI 1.35–1.90 respectively). Also, in subjects with normal levels of ALT, GGT and ALP, a dose–response increase was shown for diabetes. Conclusion Elevated levels of ALT, AST, GGT and ALP are related to a higher odds of diabetes. Also, increased levels of ALT, GGT and ALP even within normal range were independently related with the increased odds of diabetes. These results indicated the potential of elevated liver enzymes as biomarkers for the possible presence of diabetes.
Background: Type-1 diabetes (T1D) is defined as a heterogeneous autoimmune disease. Immune system related factors are important in the pathogenesis of T1D. Chemokines are important factors in the pathogenesis of several autoimmune diseases, including T1D. They are potent chemotactic cytokines with various functions such as maturation, trafficking of leukocytes, angiogenesis, and homing of stem cells. Therefore, the current study was aimed to examine whether expression of CC chemokines CCL2, CCL5, and CXCL11 is associated with disease duration and complications in Iranian T1D patients. Methods: In this experimental study, blood samples were collected from 108 T1D patients and 189 healthy controls in EDTA pre-coated tubes. The serum levels of CC chemokines were measured by ELISA. Demographic data were also collected along with experimental examinations in a questionnaire which was designed specifically for this study. Results: Results of the present study demonstrated that the expression of CCL2 was decreased while CCL5 and CCL11 were increased in T1D patients in comparison to controls. These results demonstrated that CCL2, CCL5, and CCL11 were elevated in T1D patients with duration of disease. Again, our findings demonstrated that CCL2, CCL5, and CCL11 were elevated in T1D patients with age. But there was not a significant difference between circulating level of CC chemokines studied in T1D patients regarding their gender and they have followed a similar pattern of expression in both genders. Our findings also showed that all three CC chemokines were elevated in T1D patients suffering from diabetes complications. Conclusions: According to the results of our study, elevated levels of CCL5 and CCL11 are in parallel with decreased level of CCL2 and are useful tools in the differential diagnosis of T1D from other types of metabolic disorders. Elevated levels of these CC chemokines probably could be implicated as predictive factors for occurrence of T1D complications. These results may also re-emphasize the prominent therapeutic role(s) of these CC chemokines in control of either T1D or its associated complications.
Background: Type-1 diabetes (T1D) is characterized as a heterogenous autoimmune disease. Immune system factors are important in the pathogenesis of T1D. Chemokines as crucial members of the immune system are key factors in the pathogenesis of several autoimmune diseases, including T1D. They are potent chemotactic cytokines with various functions varied from maturation, trafficking of leukocytes, to angiogenesis, angiostasis, and homing of stem cells. Therefore, the current study was aimed to examine if the expression of pro-angiogenic CXC chemokines like CXCL1 and anti-angiogenic chemochines such as CXCL9 are associated with duration and complications of T1D in Iranian diabetic patients. Methods: In this experimental study, blood samples were collected from 209 T1D patients and 189 healthy controls. The serum levels of CXCL1 and CXCL9 were measured by ELISA. Demographic data were also collected on a questionnaire which was designed specifically for this study. Results: Increased plasma levels of chemokines studied (CXCL1 and CXCL9) were observed in T1D patients compared to controls. Current findings also demonstrated that there was a close association between chemokines and complications of T1D and chemokines were elevated in T1D patients suffering complications. Conclusions: Our results probably suggest that the serum levels of CXCL1 and CXCL9 play important roles in T1D pathogenesis. It is also worth noting that these factors are useful prognostic and/or diagnostic biological markers in T1D patients.
Our investigation aimed to evaluate the prevalence of early and late menopause and its determinants in adult women of Rafsanjan cohort study. We used data obtained from the Rafsanjan Cohort Study, as a part of the prospective epidemiological research studies in Iran. In this cross-sectional research, 2002 postmenopausal women were included in the present study. Menopause age were divided into three groups (≤ 41 years, 42–54 years, and ≥ 55 years) based on the 10th and 90th percentile. The association between age at menopause with demographic and reproductive characteristics and some clinical risk factors of women was evaluated by logistic regressions. The mean age at menopause among the study participants was 48.63 ± 5.37 years. In this study, 11.49% and 11.39% of the women experienced early and late menopause respectively. After adjusting for all potential confounders, the results showed that taller and smoker women had higher odds of early menopause (OR 1.03, 95% CI 1.00–1.06) and OR 1.85, 95% CI 1.01–3.41) respectively) and women with history of using hormonal contraceptive more than median had lower odds of early menopause (OR 0.61, 95% CI 0.41–0.91). Also older women (OR 8.65, 95% CI 5.31–14.08) and women with a history of diabetes (OR 2.42, 95% CI 1.63–3.60), hypertension (OR 2.06, 95% CI 1.42–2.97), thyroid disease (OR 1.85, 95% CI 1.07–3.20) and depression (OR 2.00, 95% CI 1.35–2.97) had higher odds of late menopause. The results showed that the year of birth, height, smoking, history of diabetes, hypertension, thyroid disease and depression and using hormonal contraceptive were significantly associated with the menopausal age. Since age at menopause can affect subsequent health in women, understanding the determinants of menopausal age is important and should be pursued.
Background. Hypertension as a major risk factor for cardiovascular diseases is among the leading causes of death worldwide. The relationship between elevated serum levels of liver enzymes and hypertension has been reported in limited studies, and to the best of our knowledge, there are no previous reports in the literature on this issue in the southeast of Iran. Our investigation aimed at evaluating the relation between ALT, AST, GGT, and ALP with hypertension in the Rafsanjan Cohort Study, a city in Kerman Province, Iran. Methods. In this cross-sectional study, we used data obtained from the Rafsanjan Cohort Study (RCS), as a part of the prospective epidemiological research studies in Iran (PERSIAN). The association of the liver enzymes levels with hypertension was investigated using the multivariable logistic regression models. Results. Among 9930 participants, the mean age (±SD) was 49.94 (±9.56) years, and 46.56% were men. The odds of abnormal blood pressure significantly increased along with the higher levels of ALT, GGT, and ALP which remained significant only for ALP after adjustment for all confounding variables in both males and females (OR in males: 1.36, 95% CI = 1.09–1.69, OR in females: 1.25, 95% CI = 1.01–1.54). In subjects with normal levels of ALT, AST, GGT, and ALP, dose-response increases were observed for abnormal blood pressure in both genders. Finally, we found that, among liver enzymes, only elevated ALP was significantly correlated with the odds of stage 1 hypertension and stage 2 hypertension for both genders. Conclusions. In subjects with normal levels of ALT, AST, GGT, and ALP, dose-response increases were observed for abnormal blood pressure in both genders. Increased serum ALP activity was positively associated with increased odds of hypertension in males and females. Therefore, increased ALP could be an early indicator of hypertension.
The potential effects of opium consumption on lipid profile remain unquantified. We considered the association between opium use and dyslipidemia. In this cross-sectional study, we used data obtained from the Rafsanjan cohort study, as a part of the prospective epidemiological research studies in IrAN (PERSIAN) with detailed and validated data on opium consumption and selected other exposures. A total of 9932 adults were included in the study. Logistic regression models were used to assess the relationships of opium consumption with the prevalence of dyslipidemia and lipid disorders. In this population, 73.33% had dyslipidemia and the prevalence rates of high TC, high TG, high LDL and low HDL were 54.24%, 47.45%, 34.43% and 11.91% respectively. After adjustment for all confounders, opium users compared with non-users had lower odds ratios (OR) of high TC and high LDL [0.81 (95% confidence interval, CI 0.71–0.92) and 0.80 (95% CI 0.69–0.93) respectively] and greater OR of low HDL [1.30 (95% CI 1.04–1.62)]. Longer duration of opium consumption resulted in lower ORs of high TC, 0.68 (95% CI 0.55–0.84) and high LDL, 0.82 (95% CI 0.67–0.99), and shorter duration of opium consumption resulted in increased odds of low HDL, 1.30 (95% CI 1.02–1.66). High dose of opium consumption was associated with an OR of dyslipidemia of 0.80 (95% CI 0.65–0.97), high TC of 0.80 (95% CI 0.67–0.95), and high LDL of 0.78 (95% CI 0.64–0.96) and low dose of opium consumption, with an OR of low HDL of 1.30 (95% CI 1.02–1.65). In relation to route of consumption, opium smoking was a risk factor for low HDL with an adjusted odds ratio of 1.31 (1.04–1.63). Opium use was associated with selected changes on serum lipid levels, but opium users had higher frequency of cardiovascular disease history.
