ABSTRACT
Objective: To analyze the current status of allergic adverse reactions caused by non-ionic iodinated contrast media in patients with coronary angiography (CAG). Methods: A total of 1 225 patients who received non-ionic iodinated contrast media for CAG in our hospital from 2011-02 to 2013-09 were retrospectively studied. There were 52 patients suffered from allergic adverse reactions including 47 (90.38%) male and 5 (9.62%) female. The allergic reaction to iodixanol, iohexol, iopamidol and iopromide were in 34, 3, 3 and 12 patients respectively. The clinical symptoms and outcomes of allergic reaction in 4 iodinated contrast media were analyzed. Results: There were 40/52 (76.92%) patients with mild allergic reaction, 11(21.15%) with moderate and 1 (1.92%) with severe reaction. 13 patients had the reaction within 1 hour of contrast media injection and 39 had the reaction between 1 hour to 3 days of contrast media injection. There 34 patients were cured by symptomatic and anti-allergic treatment, 1 patient was rescued from allergic shock and no death occurred. Conclusion: Application of non-ionic iodinated contrast media in CAG is safe, while closely observe the allergic adverse reaction with the in time and symptomatic treatment is very important in clinical practice.
ABSTRACT
Objective: To analyze the relevant factors for combined use of low molecular weight heparin (LMWH) and statins causing transaminase elevation and to provide the reference for medication safety in clinical practice. Methods: There were 45 patients who received the combination of LMWH and statins treatment, then having ALT elevation in our ward from 2011-01 to 2012-12 were collected, by exclusion of patients with the history of high ALT at admission, interrupted treatment and incomplete record of liver function tests, a total of 32 patients were ifnally enrolled for investigation. The conditions for using LMWH and statins together, type of LMWH, timing of ALT elevation after medication and clinical outcomes were retrospectively analyzed. Results: All patients received statins including simvastatin, atorvastatin, rosuvastatin and pravastatin, and 15 patients took statins before using LMWH including enoxaparin, nadroparin and dalteparin. There were 18 patients had ALT increased below 3 times of the upper limit and 14 patients had ALT level ≥ 3 times of the upper limit, and ALT elevation occurred at the average of (3 ± 3.8) days after taking LMWH. All patients stopped using LMWH upon ALT elevation and 16 of them stopped taking statins. The ALT level gradually decreased to normal by application of hepatic-protective treatment in all patients.Conclusion: Combined using LMWH and statins could cause ALT elevation, LMWH and statins may have synergistic effect, and therefore, the enhanced monitor of liver function is necessary when using the combined medication.
ABSTRACT
Objective To investigate and analyze the usage of expensive outpatient prescriptions in different hospitals in Longgang area,Shenzhen,and to discuss and provide reference for the rational usage of expensive pre-scriptions.Methods Two primary hospitals,two secondary hospitals and one tertiary hospital in the Longgang area, Shenzhen,were chosen as the research targets.The expensive outpatient prescriptions,defined as the amount of pre-scription was over 150,200 and 300 yuan for primary,secondary and tertiary hospital respectively,were randomly selected and evaluated using international standards for the rational use of drugs.Results The average prescription items for primary,secondary and tertiary hospitals were 2.96,2.61 and 2.61.The largest proportions of prescription costs were 150 to 200 yuan,200 to 250 yuan and 300 to 350 yuan,which were respectively accounted for 49.6%, 56.6% and 37.7%.The frequency of using proprietary Chinese medicine,was 60.08%,68.18% and 41.62%respectively,which was not reasonable.The clinical diagnosis for the prescriptions of primary and secondary hospitals was mainly composed of trauma,bronchitis and vaginitis.The usage of drugs was not reasonable about the use of anti-biotics and infusion.In addition,the clinical diagnosis for the prescription of tertiary hospital was mainly diabetes, hypertension and cerebral infarction,where the abuse of using large dose of adjuvant drug was observed.Conclusion The frequency of using proprietary Chinese medicine is higher at all levels of hospital.In order to reduce the propor-tion of expensive prescription,the medicine institution should establish a sound system for drug use management and strengthen supervision and verification for western medicine physicians using proprietary Chinese medicine in their prescription.Furthermore,we should intervene and restrict the abuse usage of the adjuvant medicine.
ABSTRACT
<p><b>OBJECTIVE</b>To analyze the clinical features of statin-induced myopathy.</p><p><b>METHOD</b>The statin-induced myopathy case reported as adverse drug reaction (ADR) to the Beijing Center for ADR Monitoring during January 2007 to December 2012 was summarized, patients were divided to myopathy group and rhabdomyolysis group, according to the absence or presence of rhabdomylysis. The clinical characteristics, medication history and outcome were compared between the two groups.</p><p><b>RESULTS</b>A total of 160 statin-induced myopathy cases (54 in rhabdomyolysis group (33.8%) and 106 cases in myopathy group (66.3%)) were collected from the database (mean age: (64.22 ± 13.55) years old, 51.2% male, n = 82). The ADR occurred immediately after the first medication and up to 4 years after medication. Observed clinical features were myalgia, myositis, asymptommatic creatine kinase (CK) elevation or rhabdomyolysis. The average age were (68.54 ± 15.41) years old in rhabdomylysis group and (62.02 ± 12.41) years old in myopathy group (P = 0.004). There was no gender difference between the rhabdomylysis group and myopathy group (P = 0.406) . Twenty-four cases (44.4%) in rhabdomyolysis group and 26 cases (16.5%) in myopathy group were treated with high dose statin (P < 0.001). Percent of simvastatin treatment was significantly higher in rhabdomyolysis group (70.4% (38/54) ) than in myopathy group (32.1% (34/106), P < 0.001). Spearman correlation analysis showed that age, high-dose statin treatment and simvastatin use were all positively correlated with rhabdomylysis (P < 0.001), and the correlation coefficients (r value) were 0.305, 0.290 and 0.364, respectively. Four patients (aged from 71 to 85 years) died because of ADR and all 4 cases received high-dose statin treatment, 3 of them suffered from complex combined diseases, acute disease progression and complex multiple drug use history.</p><p><b>CONCLUSIONS</b>Severe statin-induced myopathy, like rhabdomyolysis, is more likely to occur in old patients, in patients taking high-dose statin, especially simvastatin.</p>

OBJECTIVE:To provide references for clinicians in the choice of antihypertensive drugs.METHODS:The antihypertensive efficacy 6 classes(or 15 kinds) of antihypertensive drugs in a monotherapy in the treatment of 370 patients with essential hypertension(EH) were compared.RESULTS:The blood pressure was effectively lowered by all of the antihypertensive drugs except doxazosin,and doxazosin and torasemide showed inferior efficacy in the reduction of diastolic blood pressure(DBP).CONCLUSION:Calcium antagonists with prolonged action,angiotensin converting enzyme inhibitor(ACEI),angiotens-in receptor antagonist,and the monotherapy of Terazosin or Indapamide can all effectively bring down the blood pressure.It is suggested that low-dose doxazosin and torasemide should not be used alone in treating essential hypertension.
