OBJECTIVES:

This study evaluated whether there is an association between the use of celecoxib and acute pancreatitis in Taiwan.

METHODS:

We conducted a case-control study using the database of the Taiwan National Health Insurance Program. The participants comprised 5,095 subjects, aged 20-84 years, with a first admission episode of acute pancreatitis from 2000 to 2011 as the cases and 20,380 randomly selected sex-matched and age-matched subjects without acute pancreatitis as the controls. The absence of celecoxib prescription was defined as "never used." Current use of celecoxib was defined as subjects who had received at least one prescription for celecoxib within 3 days before diagnosis with acute pancreatitis. A multivariate unconditional logistic regression model was used to calculate the odds ratio (OR) and 95% confidence interval (CI) for acute pancreatitis associated with the use of celecoxib.

RESULTS:

Compared with subjects who never used celecoxib, the adjusted OR of acute pancreatitis was 5.62 in subjects with current use of celecoxib (95% CI=3.33-9.46).

CONCLUSIONS:

The current use of celecoxib is associated with an increased risk of acute pancreatitis.

BACKGROUND:

Chinese medicine is commonly used and covered by health insurance to treat symptoms of uterine fibroids in Taiwan. This retrospective cohort study compared the consumption of conventional western medicine and medical cost between Chinese medicine (CM) users and nonusers among patients with uterine fibroids.

METHODS:

We extracted 44,122 patients diagnosed with uterine fibrosis between 1996 and 2010 from the National Health Insurance reimbursement database, which is a population-based database released by a government-run health insurance system. Multivariate linear regression models were used to find association between using Chinese medicine and the consumption of conventional medicine, and between using Chinese medicine and medical cost.

RESULTS:

The total fibroid-related conventional western medicine consumed by CM users was less than that by nonusers (β = -10.49, P < 0.0001). Three categories of conventional medicines, including antianemics (-3.50 days/year/patient, P < 0.0001), hemostatics (- 1.89 days/year/patient, P < 0.0001), and hormone-related agents (-3.13 days/year/patient, P < 0.0001), were used less in patients who were CM users. Moreover, although using CM increased 16.9 USD per patient in CM users annually (P < 0.0001), the total annual medical cost for treating fibroid was 5610 USD less in CM users than in nonusers (P < 0.0001).

CONCLUSIONS:

Our results suggested that CM reduced the consumption of conventional medicine, and might be a potential therapeutic substitute for conventional western medicines to treat uterine fibroids with low cost.

The purpose of this study was to examine the association of glucose variability using coefficient of variation of fasting plasma glucose (FPG-CV) and coefficient of variation of glycated hemoglobin (HbA1c-CV) to end-stage renal disease (ESRD) in 31,841 Chinese patients with type 2 diabetes.Patients with type 2 diabetes enrolled in National Diabetes Care Management Program, aged ≧30 years, and free of ESRD (n = 31,841) in January 1, 2002 to December 31, 2004 were included. Extended Cox proportional hazards regression models with competing risk of all-cause mortality were used to evaluate risk factors on ESRD incidence. Patients were followed till 2012.After a median follow-up period of 8.23 years, 1642 patients developed ESRD, giving a crude incidence rate of 6.27/1000 person-years (6.36 for men, 6.19 for women). After the multivariate adjustment, both FPG-CV and HbA1c-CV were independent predictors of ESRD with corresponding hazard ratios of 1.20 (95% confidence interval [CI] 1.01, 1.41), 1.24 (95% CI 1.05, 1.46) in HbA1c-CV from fourth to fifth quintile and 1.23 (95% CI 1.03, 1.47) in FPG-CV from fifth quintile.One-year visit-to-visit glucose variability expressed by FPG-CV and HbA1c-CV predicted development of ESRD in patients with type 2 diabetes, suggesting therapeutic strategies toward a goal to minimize glucose fluctuation.

BACKGROUND:

The purpose of this study was to assess the relationship between zopiclone use and the risk of acute pancreatitis in Taiwan.

METHODS:

This was a population-based case-control study. The data source was from the database of the Taiwan National Health Insurance Program since 2000-2011. We identified 5169 subjects aged 20-84 years with a first-time attack of acute pancreatitis as the patients and 20,676 sex-matched and age-matched subjects without acute pancreatitis as the controls. Active use of zopiclone was defined as subjects who received at least one prescription for zopiclone within 30 days before the date of diagnosing acute pancreatitis. The lack of zopiclone prescription was defined as 'never use'. We calculated the odds ratio (OR) and 95% confidence interval (CI) to assess the risk of acute pancreatitis associated with zopiclone use by the multivariable logistic regression model.

RESULTS:

After adjustment for potential confounding variables, the adjusted OR of acute pancreatitis was 2.36 for subjects with active use of zopiclone (95% CI 1.70-3.28), as compared with those with never use of zopiclone. In further analysis, as a reference of subjects with never use of zopiclone and without alcohol-related disease and biliary stone, the adjusted OR increased to 14.44 in those with active use of zopiclone and with alcohol-related disease or biliary stone (95% CI 7.47-27.89).

CONCLUSIONS:

Subjects actively using zopiclone are associated with increased risk of acute pancreatitis. Clinicians should take acute pancreatitis risk into account when prescribing zopiclone, particularly comorbid with alcohol-related disease or biliary stone.
