A 82-year-old man consulted for therapy for lung cancer in March 2010. Chest computed tomography (CT) showed a mass in right lower lobe of the lung. Fluorodeoxyglucose-positron emission tomography (FDG-PET) showed the accumulation in the mass. Lung cancer was strongly suspected and anticancer chemotherapy was started. The patient complained of difficulty in swallowing in August 2011. Gastroendoscopy revealed a submucosal mass in the gastric corpus. The specimen from the mass showed gastric metastasis from lung cancer on pathological study. The case of gastric metastasis from lung cancer is rare. When we concern the patient of lung cancer, it should be considered gastric metastasis.

Objective: Losartan/hydrochlorothiazide (HCTZ) (Preminent®) is a fixed-dose combination of angiotensin II receptor blocker (ARB) and the thiazide diuretic HCTZ that has consistently been shown to be more effective than either losartan or HCTZ. Little is known about the relationship between losartan/HCTZ and blood levels of brain natriuretic peptide (BNP).Methods and results: In this study, 44 patients with hypertension who were being treated with ARB were enrolled. The ARB was changed to losartan/HCTZ because of uncontrolled hypertension. Blood pressure (BP), pulse rate (PR), plasma levels of BNP and other biochemical parameters were analyzed at baseline and 6 and 12 months after the change from ARB. Of the total 44 patients, 33 (75%) achieved the target BP at 12 months. While there was no significant change in PR, systolic and diastolic BP were significantly reduced (-23 ± 3 mmHg and -10 ± 2 mmHg, respectively) during this period. Although there were no significant changes in biochemical parameters, plasma levels of BNP were significantly decreased, especially in patients who had higher levels of BNP at baseline, during this period.Conclusion: Losartan/HCTZ therapy significantly reduced not only BP but also plasma levels of BNP in patients with hypertension. These findings suggest that losartan/HCTZ might have cardioprotective effects in patients with higher levels of BNP. © The Author(s) 2011.

Objective To evaluate the efficacious noninferiority of subcutaneous tocilizumab injection (TCZ-SC) monotherapy to intravenous TCZ infusion (TCZ-IV) monotherapy in Japanese patients with rheumatoid arthritis (RA) with an inadequate response to synthetic and/or biologic disease-modifying antirheumatic drugs (DMARDs). Methods This study had a double-blind, parallel-group, double-dummy, comparative phase III design. Patients were randomized to receive TCZ-SC 162 mg every 2 weeks or TCZ-IV 8 mg/kg every 4 weeks; no DMARDs were allowed during the study. The primary end point was to evaluate the noninferiority of TCZ-SC to TCZ-IV regarding the American College of Rheumatology criteria for 20% improvement in disease activity (ACR20) response rates at week 24 using an 18% noninferiority margin. Additional efficacy, safety, pharmacokinetic, and immunogenicity parameters were assessed. Results At week 24, ACR20 response was achieved in 79.2% (95% confidence interval [95% CI] 72.9, 85.5) of the TCZ-SC group and in 88.5% (95% CI 83.4, 93.5) of the TCZ-IV group; the weighted difference was -9.4% (95% CI -17.6, -1.2), confirming the noninferiority of TCZ-SC to TCZ-IV. Remission rates of the Disease Activity Score in 28 joints using the erythrocyte sedimentation rate and the Clinical Disease Activity Index at week 24 were 49.7% and 16.4% in the TCZ-SC group and 62.2% and 23.1% in the TCZ-IV group, respectively. Serum trough TCZ concentrations were similar between the groups over time. Incidences of all adverse events and serious adverse events were 89.0% and 7.5% in the TCZ-SC group and 90.8% and 5.8% in the TCZ-IV group, respectively. Anti-TCZ antibodies were detected in 3.5% of the TCZ-SC group; no serious hypersensitivity was reported in these patients. Conclusion TCZ-SC monotherapy demonstrated comparable efficacy and safety to TCZ-IV monotherapy. TCZ-SC could provide additional treatment options for patients with RA. © 2014 The Authors.

Objectives. To demonstrate the pharmacokinetic equivalence of CT-P13 and its innovator infliximab (IFX) in Japanese patients with rheumatoid arthritis (RA), and to compare the efficacy and safety of these drugs, administered for 54 weeks. Methods. In a randomized, double-blind, parallel-group, multicenter study, 3 mg/kg of CT-P13 or IFX, in combination with methotrexate (MTX) (6-16 mg/week), was administered for 54 weeks to Japanese active RA patients with an inadequate response to MTX, to demonstrate the pharmacokinetic equivalence, based on the area under the curve (AUCτ) (weeks 6-14) and Cmax (week 6) of these drugs, and to compare their efficacy and safety. Results. The CT-P13-to-IFX ratios (90% confidence intervals) of the geometric mean AUCτ and Cmax values in patients negative for antibodies to infliximab at week 14 were 111.62% (100.24-124.29%) and 104.09% (92.12-117.61%), respectively, demonstrating the pharmacokinetic equivalence of these drugs. In the full analysis set, CT-P13 and IFX showed comparable therapeutic effectiveness, as measured by the American College of Rheumatology, Disease Activity Score in 28 joints, the European League Against Rheumatism, and other efficacy criteria, at weeks 14 and 30. The incidence of adverse events was similar for these drugs. Conclusion. CT-P13 and IFX, administered at a dose of 3 mg/kg in combination with MTX to active RA patients, were pharmacokinetically equivalent and comparable in efficacy and safety. © 2015 The Author(s).

Background and objectives Vitamin D has gained attention for its pleiotropic effects in areas other than bone metabolism, and the effects of vitamin D in preventing respiratory infections have been reported as one of its immunomodulating properties. This study assessed the preventive effect of vitamin D receptor activator (VDRA) on respiratory infections in dialysis patients. Design, setting, participants, & measurements Maintained Japanese hemodialysis patients (n = 508) were observed for 5 years, and the incidence of hospitalization during this period because of acute respiratory infection (ARI) was recorded. Results: Of the 508 patients, 212 had taken oral VDRA at the start of the study, whereas 296 patients had not received it. During the 5-year follow-up period, 57 patients were hospitalized because of ARIs. Kaplan-Meier analysis revealed that the incidence of hospitalization because of respiratory infection was significantly lower in patients who had been treated with VDRA compared with patients who had not (log ranktest; P = 0.02). The multivariate Cox proportional hazards model demonstrated that the patients who had taken oral VDRA were at a significantly lower risk of hospitalization because of respiratory disease (hazardratio 0.47, 95% confidence interval 0.25 to 0.90).Conclusions: The findings of this study suggest that the administration of oral VDRA has a preventive effecton the incidence of ARIs in dialysis patients. © 2011 by the American Society of Nephrology.
