Multicenter Study Observational Study
Long-term safety and effectiveness of biosimilar insulin glargine in Japanese patients with diabetes mellitus in routine clinical practice: results of a post-marketing safety study.
Objective: To evaluate the long-term safety and effectiveness of biosimilar insulin glargine (GLY) in real-world clinical practice. Methods: This prospective, non-interventional, multicenter, observational, post-marketing safety study (PMSS) enrolled Japanese patients with type 1 or 2 diabetes mellitus (T1DM or T2DM) starting GLY therapy, and was required by Japanese Pharmaceutical Affairs Law mandating post-marketing safety surveillance to acquire safety and effectiveness data of biosimilar products. Data collected from the 12-month observation included patient characteristics, adverse events, and blood glucose control. ⋯ Baseline mean hypoglycemic events/month were 1.8 and 0.1 in T1DM and T2DM, respectively: the mean change from baseline (CFB) was -1.2 (p = .066) and 0.0 (p = .915), respectively. Baseline mean HbA1c was 8.4% and 8.7% in T1DM and T2DM, respectively; the mean CFB was -0.5% (p < .001) and -0.9% (p < .001), respectively, and -1.5% (p < .001) in insulin-naive T2DM. Conclusions: This first long-term Japanese PMSS of GLY demonstrated adverse events, hypoglycemia, and glycemic control consistent with the known GLY profile for T1DM and T2DM patients, in routine clinical practice.

Randomized Controlled Trial Multicenter Study Comparative Study
Efficacy and safety of coenzyme A versus fenofibrate in patients with hyperlipidemia: a multicenter, double-blind, double-mimic, randomized clinical trial.
Background: We investigated the lipid-lowering efficacy and safety of coenzyme A (CoA) versus fenofibrate in Chinese patients with moderate dyslipidemia. Methods: A total of 417 subjects (aged 18-75 years) diagnosed with moderate dyslipidemia (triglyceride 2.3-6.5 mmol/L) from 13 large cardiovascular centers in China were recruited and randomly divided into a fenofibrate group (n = 207), which received 200 mg of fenofibrate orally once daily, and a CoA group (n = 210), which received 400 mg of CoA orally once a day. Blood lipoproteins, liver and renal function, creatine kinase, and blood glucose were measured at baseline, and after 4 and 8 weeks of treatment. ⋯ The incidence of side effects was significantly lower in the CoA group compared with the fenofibrate group (p < .05). Conclusions: Compared with fenofibrate, CoA has less effect on reducing plasma TG levels in subjects with moderate dyslipidemia. However, it has fewer adverse effects.

Multicenter Study
Long-term treatment of pulmonary arterial hypertension with macitentan in Japanese patients.
Objective: Macitentan, a novel dual endothelin receptor antagonist, was approved for the treatment of pulmonary arterial hypertension (PAH) in Japan. However, long-term effects in Japanese patients of macitentan are currently unavailable. This study sought to assess the long-term efficacy and safety of macitentan in Japanese patients with PAH. ⋯ Levels of liver enzyme and hemoglobin remained unchanged throughout the study period. Conclusions: This study suggests that the long-term use of macitentan is well tolerated and effective in Japanese patients with PAH. We concluded that macitentan can be a possible approach to reduce morbidity/mortality in Japanese PAH patients.

Objective: This paper presents and discusses recent evidence on the pathophysiological mechanisms of pain. The role of tapentadol - an opioid characterized by an innovative mechanism of action (i.e. µ-opioid receptor [MOR] agonism and inhibition of noradrenaline [NA] reuptake [NRI]) - in the modulation of pain, and the most recent pharmacological evidence on this molecule (e.g. the µ-load concept) are also presented and commented upon. Methods: Narrative review. ⋯ Of note, the reduced µ-load of tapentadol limits the risk of opioid-related adverse events, such as gastrointestinal disturbances. Moreover, the NA component becomes predominant, at least, in some types of pain, with consequent specific clinical efficacy in the treatment of neuropathic and chronic pain. Conclusions: According to these characteristics, tapentadol appears suitable in the treatment of severe uncontrolled chronic pain characterized by both a nociceptive and a neuropathic component, such as osteoarthritis or back pain.

Objective: To explore whether newly diagnosed iron deficiency anemia (IDA) is associated with subsequent systemic autoimmune disease onset. Methods: The study identified 22,440 patients who received a diagnosis of IDA between 2000 and 2012 from a random sample of 1 million people from Taiwan's National Health Insurance Research Database. The patients with IDA were randomly matched with 89,528 patients with no IDA by age, gender, and index year. ⋯ The autoimmune disease was significantly more likely to occur within 2 years after a new diagnosis of IDA. Conclusions: IDA significantly increases autoimmune disease risk, particularly in female patients and patients with certain comorbidities. Clinicians should conduct further clinical evaluations and laboratory tests of autoimmune disease in patients with IDA.
