JOURNAL OF VETERINARY INTERNAL MEDICINE, Issue 6 2007
Panagiotis G. Xenoulis
Background: Idiopathic hypertriglyceridemia has been reported in Miniature Schnauzers (MS). However, studies investigating the prevalence of this disorder in a large population of MS are lacking. Hypothesis: Hypertriglyceridemia is prevalent in healthy MS. Animals: This study used 192 healthy MS and 38 healthy dogs of other breeds (control dogs). Methods: Serum triglyceride and cholesterol concentrations were measured and statistically compared in both the MS and control group. Dogs were categorized based on their age, and median serum triglyceride concentrations were compared among different age groups. Results: A total of 63 (32.8%) of the 192 MS had serum triglyceride concentrations above the reference range. In contrast, of the 38 control dogs, only 2 (5.3%) had serum triglyceride concentrations above the reference range. The median serum triglyceride concentration in MS was 73.5 mg/dL, which was significantly higher as compared to that of the control group (median, 55 mg/dL; P= .0005). Serum cholesterol concentration was above the reference range in 9 (9.0%) of 100 MS and in 2 (5.3%) of the control dogs. Mean serum cholesterol concentrations were not significantly different between the 2 groups (P= .1374). Median serum triglyceride concentrations in MS increased significantly with age (P < .0001), and there was a significant positive correlation between serum triglyceride concentrations and age (Spearman r = 0.47; P < .0001). There was no difference in serum triglyceride concentrations between male and female MS (P= .48). Conclusion: Healthy MS have a high prevalence of hypertriglyceridemia as compared to healthy dogs of other breeds. Both the prevalence and severity of hypertriglyceridemia increase with age.

Objective To explore the risk of cardiovascular disease in patients with antineutrophil cytoplasmic antibody,associated vasculitides (AAVs) and to assess contributing risk factors. Methods In a retrospective matched-pair cohort study, 113 of 131 patients with AAVs from a vasculitis clinic registry were matched 1:1 for renal function, age at diagnosis, sex, smoking status, and previous history of a cardiovascular disease to patients with noninflammatory chronic kidney disease (CKD). Cardiovascular events were defined as acute coronary syndrome, new-onset angina, symptomatic peripheral vascular disease, stroke, and transient ischemic attack. Results Median followup times were 3.4 years for the AAV patients and 4.2 years for the CKD patients. More cardiovascular events occurred in the AAV group (23 of 113) than in the CKD group (16 of 113). Cox regression survival analysis showed a significantly increased risk of a cardiovascular event for AAV patients, with a hazard ratio (HR) of 2.23 (95% confidence interval [95% CI] 1.1,4.4) (P = 0.017). Within the cohort of AAV patients, the most strongly predictive factors were previous history of cardiovascular disease (HR 4 [95% CI 1.7,9.8]), history of dialysis dependency (HR 4.3 [95% CI 1.5,12.1]), ever having smoked (HR 3.9 [95% CI 1.5,10]), age at diagnosis (HR 1.038 [95% CI 1.006,1.072]), estimated glomerular filtration rate at remission (HR 0.977 [95% CI 0.957,0.998]), and serum cholesterol concentration at presentation (HR 0.637 [95% CI 0.441,0.92]). Conclusion In this retrospective study, patients with AAVs appear at greater risk of cardiovascular disease, with increased risk in those with a previous history of cardiovascular disease, dialysis dependency, poor renal function at remission, or a history of smoking. Measures to reduce the risk of cardiovascular disease should be integral to the management of systemic vasculitis. [source]


The metabolic syndrome in overweight epileptic patients treated with valproic acid

EPILEPSIA, Issue 2 2010
Alberto Verrotti
Summary Purpose:, To evaluate the presence of metabolic syndrome (MS) in children and adolescents treated with valproate (VPA). Methods:, One hundred fourteen patients (54 male and 60 female) were studied. These patients were followed from the beginning of therapy for at least 24 months; at the end of follow-up, 46 patients (40.4%) had a considerable increase in body weight, whereas the other patients (59.6%) remained with the same weight. The MS was defined as having at least three of the following: abdominal obesity, dyslipidemia, glucose intolerance, and hypertension. Results:, Forty-six patients developed obesity; 20 (43.5%) of 46 patients developed MS. Abnormal glucose homeostasis was identified in 45% of patients. High total serum cholesterol concentrations were noted in 10 (50%), high serum triglyceride concentrations in 7 (35%), and low high-density lipoprotein (HDL) in 15 (75%) of the 20 subjects with MS. However, there were no significant differences in the features of MS between boys and girls with MS. Conclusions:, Patients who gain weight during VPA therapy can develop MS with a possible risk of cardiovascular disease. [source]


Effect of sodium phytate supplementation on fat digestion and cholesterol metabolism in female rats

JOURNAL OF ANIMAL PHYSIOLOGY AND NUTRITION, Issue 11-12 2005
C. Yuangklang
Summary The effects of sodium phytate supplementation on fat digestion and cholesterol metabolism were investigated in female rats. On the basis of an in vitro experiment showing that phytate raised the solubility of bile acids, it was predicted that phytate feeding would depress faecal bile acid excretion, raise apparent fat digestibility and elevate serum cholesterol concentrations. The experimental diets with or without sodium phytate were either cholesterol-free or cholesterol-rich and had a normal calcium concentration. Rats fed on the cholesterol-rich diet with sodium phytate showed enhanced faecal bile acid excretion, but there was no effect on fat digestibility. In rats fed the cholesterol-free diets, phytate did neither affect fat digestion nor bile acid excretion. Sodium phytate inclusion in the cholesterol-rich diet raised serum cholesterol concentrations, but reduced liver cholesterol concentration. Thus, the in vivo data do not agree with the in vitro observations. Both phytate and cholesterol feeding influenced mineral and trace element metabolism. Liver zinc concentrations were raised by phytate feeding. Cholesterol consumption reduced hepatic concentrations of copper, iron and zinc. Both phytate and cholesterol feeding reduced the apparent absorption of calcium, magnesium and phosphorus. [source]

Systemic toxicity of tacrolimus given by various routes and the response to dose reduction

CLINICAL & EXPERIMENTAL OPHTHALMOLOGY, Issue 1 2005
Laboratory Science
Abstract Purpose:,To evaluate the long-term systemic toxicity of tacrolimus (FK-506) administered by various routes, and to assess the effect of dose reduction on toxicity. Methods:,The study animals were 120 experimentally naïve adult female Wistar rats weighing 200,250 g each. The rats were randomly divided into 10 equal groups (n = 12 in each) and treated with tacrolimus administered topically (in drops, 0.3%, q.i.d.), intravitreally (0.5 mg/kg bodyweight/week), intramuscularly (1 mg/kg bodyweight/week), low-dose intravenously (1 mg/kg bodyweight/week) and in high-dose intravenously (2 mg/kg bodyweight/week) for 3 months. The rats in the control groups (one for each different route of administration) were treated with 0.9% NaCl. The blood concentration of tacrolimus, complete blood count and biochemistry parameters were measured each month for the 3-month study period. Results:,The rats in the control groups and experimental groups administered topical and intravitreal tacrolimus did not demonstrate any systemic toxic effects. The rats that developed certain toxic effects (hyperglycaemia, hyperkalaemia and nephrotoxicity) in the groups given low-dose or high-dose i.v. tacrolimus responded well to dose reduction. Following dose reduction, blood glucose concentrations decreased from 247.4 ± 42.3 mg/dL to 189.6 ± 37.9 mg/dL (P < 0.05), and from 237.4 ± 41.1 mg/dL to 182.3 ± 22.7 mg/dL (P < 0.05) in the low- and high-dose i.v. tacrolimus-treated rats, respectively. The rats that developed impaired hepatic function after high-dose tacrolimus did not respond to dose reduction. Baseline cholesterol concentrations for the intramuscular and low- and high-dose i.v. tacrolimus-treated groups, demonstrated decreases, respectively, from 87.4 ± 14.0 mg/dL, 86.4 ± 14.0 mg/dL and 90.4 ± 14.3 mg/dL to 53.6 ± 9.8 mg/dL, 52.1 ± 12.5 mg/dL and 63.5 ± 11.7 mg/dL by the end of the second month. The differences were found to be statistically significant (P < 0.05 for each result). Conclusion:,Topical or intravitreal administration of tacrolimus seems to be systemically safe whereas parenteral administration can cause some systemic haematological changes such as dose-dependent decreased serum cholesterol concentrations. Dose reduction may prevent such adverse effects. [source]
