The safety and efficacy of fimasartan have been evaluated through post-marketing surveillance in real world clinical practice. The multi-center, prospective, open-label and non-interventional study. A total of 3,945 patients (3,729 patients for safety assessment and 3,473 patients for efficacy assessment) were screened in patients with essential hypertension in 89 study centers from 9 September 2010 through 8 September 2016. Among the total patients, 2,893 patients (77.6%) were administered fimasartan for 24 weeks or longer and were classified as ‘patients with long-term follow-up’, and the additional safety and efficacy analysis were performed. The improvement was defined as systolic blood pressure (SBP) controlled to ≤ 140 mmHg or decreased SBP differences ≥ 20 mmHg after treatment or diastolic blood pressure (DBP) controlled to ≤ 90 mmHg or decreased DBP differences ≥ 10 mmHg after treatment. Adverse drug reactions (ADRs) were reported in 3.8% patients; dizziness, and hypotension were the most frequently reported ADRs in total patients. The results of patients with long-term follow-up were comparable with total patients. The overall improvement rate in all efficacy assessment at the last visit was 87.1% (3,025/3,473 patients). The overall improvement rate of the patients with long-term follow-up was 88.9%. Fimasartan was well tolerated, with no new safety concerns identified and an effective treatment in the real world clinical practice for Korean patients with hypertension.

Oral antibiotics are usually prescribed for geriatric patients for the treatment of infectious diarrhea and management of hepatic encephalopathy. But oral antibiotics have systemic adverse events, so many doctors face the issue of choosing the right antibiotics. Rifaximin, an intestinal topical antibiotic that exhibits a wide antimicrobial activity against both aerobic and anaerobic bacteria, has various indications, such as acute bacterial diarrhea caused by Gram positive and negative bacteria, traveler's diarrhea, small intestine bacterial overgrowth, prevention of infection after gastrointestinal surgery, and the management of hepatic encephalopathy with hyperammoniemia. But there are few clinical trial data on the geriatric population. Hence we reviewed the clinical study data that included geriatric patients in their clinical trials. Based on our literature searches, only one clinical trial on acute bacterial diarrhea was performed only for geriatric patients. Other clinical trials for various indications usually recruited elderly patients, but the number of elderly patients was limited. However, generally speaking, rifaximin showed good efficacy and safety profile in acute bacterial diarrhea caused by Gram positive and negative bacteria, traveler's diarrhea, small intestine bacterial overgrowth, prevention of infection after gastrointestinal surgery, and the management of hepatic encephalopathy with hyperammoniemia; and there were no differences in efficacy and safety, compared to the nongeriatric population. We concluded that rifaximin is a good therapeutic option for various gastrointestinal indications, and shows good efficacy and an excellent safety profile, compared to other oral agents. For more evidence on the geriatric population, we propose clinical trials on elderly patients for each indication.

Endomyocardial biopsy often fails to show myocardial inflammation for patients with clinically suspected myocarditis. The serum isoforms of troponin T (cTnT) level is a very sensitive marker of myocardial injury and it is elevated even in the absence of myocardial inflammation. We investigated the correlations for myocardial injury, virus titers and inflammation in acute viral infection. Using the murine coxsackievirus group B3 (CVB3) myocarditis model, the histopathologic findings and virus titers in mouse hearts were compared with the serum cTnT levels measured by ELISA at various time points. Viable virus titers in the hearts peaked at 3 days after infection (8.22+/-0.13 log10 PFU/100 mg of heart); they decreased at day 7 and no viable virus was detected from day 14. Myocardial inflammation was minimal at day 3, peaked at day 7 and markedly decreased at day 14. The individual serum TnT levels were significantly increased at day 3 (7.37+/-1.46 ng/ml), persisted to day 7 (0.73+/-0.08 ng/ml), and normalized at day 14. Serum cTnT levels were correlatable with virus titers in the heart (r=0.744, P <0.01), but the serum cTnT levels were not correlated with the degrees of inflammation. Using the less myocarditic strain of CVB3, similar relationships were observed between the changes for the serum cTnT levels and the heart virus titers. During the course of viral infection, myocardial injury precedes the pathologic evidence of inflammation, and the elevated cTnT levels provide evidence of myocardial injury even in the absence of any histologic findings of myocarditis.

In order to evaluate the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections in terminally failing hearts, we screened the explanted hearts of transplantation recipients for the presence of HBV DNA and HCV RNA. DNA and RNA extractions were taken from explanted failing hearts (N=7) and normal hearts (N=). Polymerase chain reaction (PCR) and in situ PCR of HBV or reverse transcription-polymerase chain reaction (RT-PCR) and in situ RT-PCR of HCV were performed. The positivity of HBV in failing hearts was 63% (17/27) and it was 50% (3/6) in normal hearts in PCR. There was no significant difference in the positivity of HBV DNA between failing and normal hearts. The positivity of HCV in failing hearts was 18.5% (5/27) and it was 16.7% (1/6) in normal hearts in nested RT-PCR. There was no significant difference in the positivity of HCV RNA between failing and normal hearts. HCV was very rarely observed in explanted terminally failing hearts and HBV was frequently found in both explanted failing hearts and normal hearts. We concluded that these viruses have little direct causal relationship with the development of heart failure.

Autosomal dominant polycystic kidney disease is a systemic disorder with cystic manifestations in the kidneys, liver, pancreas, seminal vesicles, and meninges; its noncystic manifestations affect mostly the vascular, cardiac, and connective tissues. Cardiovascular abnormalities, including mitral and aortic valvular prolapse and regurgitation and annuloaortic ectasia, have been considered important extrarenal manifestations of autosomal dominant polycystic kidney disease. But there were no reports with dilated cardiomyopathy in patients with polycystic kidney disease yet. We have experienced a case of dilated cardiomyopathy that is associated by autosomal dominant polycystic kidney disease in 40 year old male patient. Abdominal ultrasonography revealed variable sizes of multiple cysts in both kidneys and echocardiography showed the marked dilatation of left ventricle and severely depressed left ventricular systolic function (ejection fraction=19%). He was treated with diuretics intravenously and orally. Then dyspnea and abdominal distension was improved. This is the first case of dilated cardiomyopathy with autosomal dominant polycystic disease in Korea.

BACKGROUND: Coronary artery spasm is an important mechanism in producing myocardial ischemia. But the exact mechanism of the spasm is not well known. We investigated the mutation of endothelial nitric oxide synthase (eNOS) that produce nitric oxide and relationship between eNOS mutation and coronary artery spasm.

Infective endocarditis is the infectious disease that produces vegetation on endocardium. Acute bacterial endocarditis is most frequently caused by Staphylococcus aureus, occurs on a normal heart valve, and subacute endocarditis usually caused by Streptococcus viridans occurs on damaged valves. Gemella haemolysans are gram-positive cocci that is placed in the family Streptococcaceae. As opportunistic pathogen, Gemella haemolysans are able to cause severe localized and generalized infections and it is known that this organism very rarely causes infective endocarditis. The paucity of reports concerning Gemella haemolysans is probably related to the difficulties associated with their identification. Several laboratory tests to prevent misinterpretation of this organism are now suggested. We have experienced a case of infective endocarditis that is caused by Gemella haemolysans in 37 year old male patient with ventricular septal defect. Gemella haemolysans were detected by blood culture and he was treated with intravenous vancomycin with gentamicin and ceftriaxone, and also underwent cardiac surgery. This is the first case of Gemella haemolysans endocarditis of ventricular septal defect in Korea.
