Coronary artery calcium score assessed by a 64 multislice computed tomography and early indexes of functional and structural vascular remodeling in cardiac syndrome X patients.

Background. Regardless of normal coronary angiograms, coronary artery calcium (CAC) can be found in cardiac syndrome X (CSX) patients. According to some data, a relationship between the CAC score and markers of early atherosclerosis in CSX has been observed. Our aim was to assess whether the extent of the CAC score assessed by multislice computed tomography (MSCT) with a 64-slice system in CSX patients is related to brachial artery reactivity, intima-media thickness (IMT), and arterial compliance indexes.Methods and Results. High-resolution ultrasound was used to measure flow-mediated dilatation (FMD) and nitroglycerin-mediated vasodilatation, as well as the following parameters of arterial structural changes: IMT, pulse wave velocity, total arterial compliance, and stiffness index. MSCT was used to assess the presence and the quantity of CAC. The study group consisted of 46 CSX patients (mean age, 56.3±9 years), whereas the control group comprised 21 healthy subjects (mean age, 54.9±7 years). The assessment of the vascular parameters showed significantly decreased FMD and increased IMT in the CSX subjects (9.06%±3.2% and 0.67±0.1 mm, respectively) in comparison to the control subjects (17.42%±8.4% [P=.008] and 0.57 ± 0.2 mm [P=.021], respectively). CAC was detectable in 19 CSX patients (41%) (CAC range according to Agatston score, 2–500; mean, 101.6; median, 26.5) and in 1 control subject (4.8%) (CAC value, 13). CSX patients with detectable CAC were characterized by a significantly higher age (P=.001), lower body mass index (P=.017), and increased stiffness index (P=.020); there were no differences in FMD and IMT values. In a multivariate logistic and linear regression analysis, age was the only risk factor independently associated with the presence of CAC (P=.001) and the log(CAC+1) value (P=.01). In the subgroup of women, log(CAC+1) significantly correlated with age (r=0.587, P=.002) and stiffness index (r=0.427, P=.024), and in a borderline significant manner, it correlated with weight (r=−0.329, P=.07) and waist-hip ratio (r=0.315, P=.07). There were no significant correlations in the male subgroup.Conclusions. Low ranges of CAC are frequently detectable in CSX patients, and the results are age-related and independent of impaired early indexes of functional and structural vascular remodeling.

Growth hormone/insulin-like growth factor-1 axis, calciotropic hormones and bone mineral density in young patients with chronic viral hepatitis

INTRODUCTION Chronic liver disease caused by HBV and HCV infections, due to its great prevalence and serious medical consequences, is at the present time a significant clinical problem. An impaired liver function can provoke severe disturbances in calcium and phosphorus homeostasis, and consequently in the bone metabolism resulting in hepatic osteodystrophy. The aim of this study was to determine whether there are significant differences in bone mineral density (BMD) and/or circadian levels of hormones connected with bone metabolism and bone turnover markers in patients with chronic viral hepatitis. MATERIAL AND METHODS Circadian levels (AUC, area under the curve) of GH, IGF-I, IGFBP-3, osteocalcin (BGLAP), C-terminal telopeptide of type I collagen (ICTP), PTH, 25(OH)D, total calcium and total phosporus were measured in the blood of members of the study group (n = 80). BMD was assessed using the dual-energy X-ray absorptiometry method of the L2-L4 lumbar spine. Data was compared to that of healthy individuals (n = 40). RESULTS BMD (1.05 g/cm3 vs. 1.20 g/cm3), total calcium concentration (2.20 mmol/L vs. 2.45 mmol/L), total phosphorus concentration (1.06 mmol/L vs. 1.33 mmol/L), IGF-I (AUC 3,982.32 ng/mL vs. 5,167.61 ng/mL), IGFBP-3 (AUC 725.09 ng/L vs. 944.35 ng/L), 25(OH)D (AUC 356.35 ng/mL vs. 767.53 ng/mL) and BGLAP (AUC 161.39 ng/L vs. 298 ng/L) were lower in the study group. GH (AUC 88.3 ng/mL vs. 48.04 ng/mL), iPTH (AUC 1,201.94 pg/mL vs. 711.73 pg/mL) and ICTP (AUC 104.30 μg/L vs. 54.49 μg/L) were higher in patients with hepatitis. Positive correlations were noted between bone mineral density and IGF-I, IGFBP-3, and BGLAP levels. CONCLUSIONS Chronic viral hepatitis causes a decrease in bone mineral density. Impaired liver function disrupts homeostasis of the calcium- vitamin D-parathyroid hormone axis and provokes secondary hyperparathyroidism. Chronic viral hepatitis induces a decrease in the synthesis of IGF-I and IGFBP-3 and an increase in GH secretion. Hepatic osteodystrophy is probably caused by both changes in calciotropic hormones as well as in the somatotropin hormone axis.

Vascular and cardiac function in young adults with classical congenital adrenal hyperplasia

INTRODUCTION Patients with classical congenital adrenal hyperplasia (CAH) have increased cardiovascular risk, but the vascular and cardiac function during longitudinal corticoids replacement therapy is not known thoroughly. MATERIAL AND METHODS Cross-sectional study of 19 Caucasian adults with CAH (age 23.7 ± 3.8 years; twelve males) compared to 20 healthy volunteers matched for origin, sex, age, and body mass index (BMI). All of the participants were assessed for flow mediated dilatation of the brachial artery (FMD), intima-media thickness of the common carotid artery (cIMT) and common femoral artery (fIMT), standard echocardiography, and global longitudinal left ventricular function using two-dimensional speckle-tracking echocardiography (LSTE). RESULTS The patients with CAH, compared with controls, had decreased FMD (9.4 ± 3.9 vs. 19.8 ± 5.2; p < 0.01), and the difference was still significant after correction for potential confounders. cIMT and fIMT were higher in the CAH group at baseline (for cIMT 0.47 ± 0.4 mm vs. 0.40 ± 0.03 mm; p < 0.01, for fIMT 0.47 ± 0.05 mm vs. 0.41 ± 0.04 mm; p < 0.01) but not after correction for potential confounders. The CAH subjects, compared with controls, had normal or similar left ventricular (LV) ejection fraction and LV mass index. The mean absolute value of LSTE differed in the CAH patients compared with controls (-20.5% ± 1.2 vs. -22.5% ± 1.7; p < 0.01), but it was still within the normal range. CONCLUSIONS Young adults with CAH and glucocorticoid long-lasting treatment had impaired FMD, an insignificant increase of IMT, and subclinical changes in LV diastolic function in echocardiography.

CASE REPORT Reactive arthritis after application of intravesical BCG immunotherapy in bladder cancer

tal structure was obtained. Such tests as: bacterial cultures, both mycobacterium culture and PCR test on genetic material of mycobacterium were negative. We took bacterial culture of blood and urine which did not disclose any additional information. There were no antibodies against antigens such as Mycobacterium tuberculosis. Blood tests for the presence of Varicella-Zoster Virus, Influenza Virus type A(H1N1), type A(H3N2), type B, Yersinia enterocolitica, Toxoplasma gondii, Borrelia afzelii, Borrelia burgdorferi, Chlamydia trachomatis, and Chlamydia pneumoniae, which are the most common cause of post infectious reactive arthritis, were negative too. Also antibodies against ANA Hep-2 and rheumatic factor were not detected. Because the urosepsis was suspected antibiotics ceftazidime 6 g/day and ciprofloxacin 800 mg/day iv were applied, yet neither fever, nor the level of inflammatory parameters did not decrease. Having excluded infection, it was acknowledged that reactive arthritis triggered by BCG immunotherapy was the reason for patient complaints. Methylprednisolone 32 mg/day and meloxicam 15 mg/day were applied and after 7 days a decrease in the level of CPR to 16.9 mg/l and swelling of the joints were observed. The amount of drugs was gradually reduced during the 4 weeks. The patient’s complaints, the level of inflammatory parameters, and tests on presence of HLA B27 antigen were negative during the medical inspection after 3 months. dISCuSSIon
