BACKGROUND/OBJECTIVE: Effects of atorvastatin (Lipitor) drug monotherapy (10 mg daily) on fasting blood lipid profiles and cardiovascular disease (CVD) risks were examined for a single subject with C5-C6 tetraplegia. Routine fasting lipid profiles were analyzed by standard biochemistry techniques for total cholesterol (TC), triglycerides (TG), low-density lipoprotein-cholesterol (LDL-C), and high-density lipoprotein-cholesterol (HDL-C). Lipid profiles were analyzed on 3 occasions before drug therapy was initiated and 3 months after therapy commenced. The TC:HDL and LDL:HDL ratios were computed for all sampling times and used to assess pretreatment and post-treatment CVD risk. RESULTS: Fasting TC, TG, and LDL-C were all significantly reduced by therapy. The pretreatment HDL-C of 35 mg/dL was lowered to 21 mg/dL. As a result, the TC:HDL risk ratio was only marginally reduced from 6.6 to 6.4, whereas the LDL:HDL risk ratio remained unchanged by treatment. CONCLUSIONS: In this man with tetraplegia, atorvastatin drug monotherapy rapidly lowered TC, TG, LDL-C, and HDL-C. However, the TC:HDL ratio, considered the best predictor of CVD risk, was unchanged. 相似文献

BACKGROUND: Renal transplant recipients are at increased risk of atherosclerotic vascular disease with hyperlipidemia. Many recipients have preexisting cardiovascular disease at the time of transplantation, and immunosuppressive therapy may aggravate existing risk factors or promote development of new risk factors, notably hyperlipidemia and hypertension. Fluvastatin is one of the statins, an HMG-CoA reductase inhibitor, which has been shown to be effective in lowering cholesterol levels. We treated hyperlipidemia after renal transplantation with Fluvastatin for more than 6 months.We attempted to clarify the efficacy of fluvastatin on hyperlipidemia in renal transplant recipients. MATERIALS: Forty-five renal transplant recipients with hyperlipidemia were enrolled in this study. The mean age was 44.2 years, with 23 men and 22 women. Thirty-seven transplantations were from a living related donors and eight from cadaveric donors. Thirty-three recipients were ABO-compatible, seven recipients had minor mismatches, and five recipients were ABO-incompatible. The dose of fluvastatin was 20 mg per day. Levels of total cholesterol (TC), triglyceride (TG), HDL cholesterol (HDL-C), LDL cholesterol (LDL-C), serum creatinine (s-Cr), ALT, ALP, uric acid (UA), hematocrit (Ht), CPK, and blood pressure were examined in all recipients before treatment as well as 1, 3, and 6 months after Fluvastatin administration. RESULTS: The mean levels of TC and TG were significantly reduced from 256, to 224 and 215 mg/dL, and from 188 to 170 and 147 mg/dL at 1 and 6 months after treatment, respectively. The mean levels of HDL-C were 72 mg/dL before treatment, 81 mg/dL at 1 month, and 80 mg/dL at 6 months after treatment. The mean levels of LDL-C were 153 mg/dL before treatment, 145 mg/dL at 1 month, and 145 mg/dL at 6 months after treatment. Fluvastatin significantly produced a reduction rate in TC of 16%, TG of 22%, and LDL-C of 5% after 6 months of treatment, respectively. The mean levels of HDL-C of were increased 10% after 6 months of treatment. The serum creatinine and CPK were not significantly different. There were no clinically significant differences in other factors. No significant adverse effects were observed. CONCLUSIONS: Fluvastatin seemed to be safe and highly effective to control TC, TG, LDL-C, and HDL-C in renal transplant recipients. 相似文献

We investigated tolerability and efficacy of ezetimibe treatment (10 mg/d) in 25 heart allograft recipients already on stable statin therapy. Total cholesterol (TC), low-density cholesterol (LDL-C), high-density cholesterol (HDL-C), triglycerides (TG), immunosuppressant drug levels, laboratory and clinical parameters were assessed before, four months and one yr after initiation of ezetimibe treatment. Mean equivalent statin dose was 53.5 +/- 12.3 mg of pravastatin, remaining unchanged throughout the study period. Ezetimibe was generally well tolerated, only two patients (8%) discontinued ezetimibe due to stomach pain or headache. Mean TC decreased from 231.8 +/- 6.4 mg/dL before therapy to 202.2 +/- 8.8 mg/dL after four months and 192.9 +/- 7.0 mg/dL after one yr (p < 0.001). Mean LDL-C decreased from 143.1 +/- 5.4 mg/dL to 121.4 +/- 7.9 mg/dL (month 4; p < 0.05) and 107.1 +/- 5.6 mg/dL (one yr; p < 0.001). TG decreased from 182 +/- 14.3 mg/dL to 173.3 +/- 17.5 mg/dL after one yr (p < 0.05), whereas HDL-C was unchanged. Initial LDL-C and cardiac diagnosis before transplantation were identified as predictors of absolute LDL-C reduction. Immunosuppressant drug doses and blood concentrations were unchanged as well as other laboratory and clinical parameters. Ezetimibe appears safe and effective for further reduction of TC and LDL-C in heart allograft recipients already on stable statin therapy. Extent of pre-treatment LDL-C and cardiac disorder prior to transplantation appear to correlate with the efficacy of ezetimibe therapy. 相似文献

Differential impact of aging and gender on lipid and lipoprotein profiles in a cohort of healthy Chinese Singaporeans 总被引:2,自引:0,他引:2
Aim: To evaluate the impact of age and gender on lipid and lipoprotein profiles and the burden of dyslipidemia in a cohort of healthy Chinese Singaporean. Methods: A total of 1 775 healthy Chinese, 536 men and 1 239 women aged between 30 and 70 years old were involved in the present study. Results: Gender differences in all lipid and lipoprotein levels were clearly evident. Singaporean Chinese men have significantly higher levels of total cholesterol (TC), triglyceride (TG), low density lipoprotein-cholesterol (LDL-C) and total cholesterol/high density lipoprotein-cholesterol (TC/HDL-C), and lower levels of HDL-C than women. Although lipid and lipoprotein levels in men did not change in the different age groups, those in women, especially TC, LDL-C and TC/HDL-C, were significantly higher in older women (〉 50 years old) than corresponding levels in younger women (30-46 years old). Furthermore, TG was significantly correlated with lipids and lipoproteins differently in men and women. If 100 mg/dL of LDL-C were to be adopted as the therapeutic cut-off level, then the burden of care will be huge as approximately 90% of both Chinese men and women have LDL-C greater than 100 mg/dL. Condusion: In light of the findings of the present study, we suggest that preventive measures to promote the reduction in risk of coronary heart disease (CHD) must address the high proportion of men and women with high LDL-C, and that these measures should take into account both the gender and age factors. For men, reduction of high cholesterol must start early in life, whereas for women, steps must be taken earlier to mitigate the anticipated sharp increase in risk, especially after menopause. 相似文献

Combined treatment with low-dose pravastatin and fish oil in post-renal transplantation dislipidemia 总被引:4,自引:0,他引:4
BACKGROUND: The most common cause of post-transplant dyslipidemia is the use of corticosteroids and cyclosporin-A (CyA). The HMG-CoA reductase inhibitors have emerged as the agents of first choice in the treatment of post-transplant hyperlipidemia in combination with low fat diet. The objective of this study was to evaluate the efficacy of combined treatment with low-dose pravastatin and fish oil in post-renal transplantation dislipidemia. PATIENTS AND METHODS: Twenty-four renal transplant patients, 15 men and 9 women aged from 30 to 60 years with stable renal function were included in this study. All patients were transplanted from living related donors and were given a stable triple immunosuppressive therapy, with methylprednisolone, azathioprine and CyA. All patients were also given a standard diet containing 1 g/kg BW protein, reducing the daily fat to less than 30%, and maintaining at least a 1:1 ratio of saturated to polyunsaturated (or monounsaturated) fats. A dosage of 20 mg pravastatin (pravachol) and 1 g of fish oil (prolipid) were added to the diet after dinner, according to our protocol. Blood samples were taken after each study period for total cholesterol, LDL-cholesterol, triglycerides, Apo A(1), Apo B, Lp(a), creatinine, CPK and fibrinogen determination. RESULTS: At the end of the therapeutic protocol with pravastatin a significant reduction (p < 0.02) of total and LDL-cholesterol was observed, but no significant change in triglycerides, HDL, Lp(a), Apo A(1), Apo B and fibrinogen was shown. At the end of the therapeutic protocol with pravastatin and fish oil supplement significant changes were seen in TC (p < 0.02), TG (p < 0.03), LDL-C (p < 0.03), Apo A(1) (p < 0.04) and Apo B (p < 0.05) concentrations. There were no significant changes in HDL-C and Lp(a) concentrations. Renal function and cyclosporine levels were not changed during and after the study. CPK was increased only in one case. CONCLUSIONS: It is suggested that if the response to the diet is inadequate, the use of combined treatment with low-dose pravastatin and fish oil is a more effective strategy than the pravastatin treatment alone for changing the lipid profile after renal transplantation. 相似文献
