ABSTRACT We conducted a case-control study to examine the impact of coronal heart disease (CHD) risk factors on calcium oxalate (CaOX) stone formation.
Variables included body mass index (BMI), current alcohol use, smoking habit, hypertension, hypercholesterolemia, diabetes mellitus, and hyperuricemia. Data suf fi cient for analysis were obtained for 181 CaOX stone formers and 187 controls.
Seven of 181 stone formers (3.9%) had a history of CHD compared with none of 187 control subjects (P = 0.007). In univariate logistic regression analysis, smoking habit (OR 4.41, 95% CI 2.85-6.84, P < 0.0001), hypertension (OR 4.24, 95% CI 2.61-6.91, P < 0.0001), hypercholesterolemia (OR 3.03, 95% CI 1.77-5.20, P < 0.0001) and BMI (OR 1.10, 95% CI 1.04-1.17, P = 0.007) reached statistical signi fi cance. In a multivariate logistic regression analysis, smoking habit (OR 4.29, 95% CI 2.68-6.86, P < 0.0001), hypertension (OR 3.57, 95% CI 2.11-6.07, P < 0.0001), and hypercholesterolemia (OR 2.74, 95% CI 1.51-5.00, P = 0.001) reached statistical signi fi cance, while BMI (OR 1.06, 95% CI 0.99-1.12, P = 0.09) did not.
CaOX stone formers are signi fi cantly associated with several CHD risk factors, including smoking habit, hypertension, hypercholesterolemia, and obesity.

    ABSTRACT: Aim The main objective of the study was to determine the urinary risk factors involved in kidney stone formation. Method In this study total number of 101 patients (64 male and 37 female) between the age group 2-70 years were selected. Personal characteristics like age, family history, clinical sign and symptoms, education, monthly income, living style, smoking or tobacco chewing habit, dietary intake and daily amount of drinking water were recorded. Results The study showed that the risk for developing kidney stone formation was high in median age group (16-25 years) both in male and female population. The most important factors associated with this were lack of drinking clean water, over weight and obesity as well as family history (37.5% and 27.02% in men and women respectively). Conclusion Our study has confirmed that lack of drinking sufficient amount of water, increasing weight and obesity and family history are some major factors contributing to the increased risk of kidney stone formation. Therefore it is very important to live a healthy life, drink clean water and control weight to prevent such diseases.

    ABSTRACT: BACKGROUND: The reported risk of coronary heart disease (CHD) in patients with a history of kidney stones is conflicting. AIMS: The objective of this meta-analysis was to assess the association between a history of kidney stones and CHD risk. MATERIALS AND METHODS: A literature search was performed using MEDLINE, EMBASE, and Cochrane Database of Systematic Reviews from inception until April 04, 2014. Studies that reported odds ratios or hazard ratios comparing the risk of CHD in patients with a history of kidney stones versus those without a history of kidney stones were included. Pooled risk ratios (RRs) and 95% confidence interval (CI) were calculated using a random-effect, generic inverse variance method. RESULTS: Seven study populations from four cohort studies and one cross-sectional study were identified and included in the data analysis. The pooled risk ratio (RR) of CHD in patients with kidney stones was 1.24 (95% CI, 1.10-1.40). This result remained significant (RR, 1.23 [95% CI, 1.08-1.41]) when the sensitivity analysis was restricted to only cohort studies. A history of kidney stones was associated with increased CHD risk in females (RR, 1.43 [95% CI, 1.12-1.82]), whereas the association was not significant in males (RR, 1.14 [95% CI, 0.94-1.38]). CONCLUSIONS: Our study demonstrates a statistically significant increased risk of CHD in female patients with prior kidney stones. This finding suggests that a history of kidney stones is a risk factor for CHD in females and may impact clinical management.

    ABSTRACT: Aim: To determine the prevalence of carotid artery calcification (CAC) detected in routine dental radiography (PRs) in patients with kidney stones (KSs) and to investigate the relationship between CAC-atherosclerosis and KSs. Materials and methods: A total of 108 patients with renal stones were included in the present study. A history of renal colic, with confirmed hematuria and voiding of the calculus, radiographic evidence of KSs, or previous surgical and endoscopic removal of KSs, was used to define the nephrolithiasis. KS patients were evaluated by PR in terms of the presence of CAC. Subjects with either unilateral or bilateral CAC on these radiographs were identified. Results: Of the 108 patients included in the data analysis, 18 (16.6%) were detected as having CAC upon PR; of these, there were 8 males (11.5% of all males) and 10 females (25.6% of all females) (P > 0.05). There was no significant difference between the patients with CAC and the patients without CAC in any aspect of biochemical parameters, and also in the history of predisposing factors (P > 0.05). The CAC prevalence (16.6%) was significantly higher in patients with KSs when compared to the normal population (5.06%) in our previous study (P > 0.05). Conclusion: Our study shows that CAC is significantly higher in patients with KSs when compared to the normal population. This study may draw the attention of clinicians to the fact that patients with KSs should be evaluated further for atherosclerosis and treated for vascular risk factors.
