Adrenocorticotropic hormone (ACTH) and cortisol reportedly play a role in glycemic control in patients with type 2 diabetes mellitus (T2DM); however, the underlying mechanism remains controversial. We retrospectively investigated the effect of tofogliflozin on serum ACTH and cortisol levels in elderly patients with T2DM.Patients received 20 mg tofogliflozin daily for 3 months. Serum ACTH and cortisol levels were measured at baseline, as well as after 1 month and 3 months of tofogliflozin therapy.Serum ACTH levels were significantly reduced 3 months after tofogliflozin treatment (P < .01). Additionally, serum cortisol levels were reduced 3 months after tofogliflozin treatment, demonstrating borderline significance (P = .05). The higher body mass index (BMI; ≥25 kg/m2) group showed higher ACTH and cortisol levels than the lower BMI (<25 kg/m2) group, with borderline significance (P = .05). Renin levels were significantly increased 1 month after treatment (P < .05), maintaining serum aldosterone levels in parallel with the extracellular fluid.Our findings suggested that tofogliflozin decreased both serum ACTH and cortisol levels, with higher levels observed in the high BMI group. Tofogliflozin increased serum renin levels while maintaining serum aldosterone and extracellular fluid levels. Collectively, tofogliflozin could affect the hypothalamic-pituitary-adrenal pathway in patients with T2DM, especially in the low BMI group.
Mitral valve replacement in the presence of severe annular calcification and an infectious lesion may be complicated by atrioventricular rupture, left circumflex coronary artery injury, and recurrence of infective endocarditis. Confronted with these circumstances, we have developed a technique of annular reconstruction for mitral valve replacement. The prosthetic valve is made by enlarging the circumference of the sewing ring with a Dacron collar. The collar can be sutured to the left atrial wall above the mitral annulus. This technique has been employed in five patients: three had extensive annular calcification, and two had acute valve endocarditis with destruction of mitral annulus. In all cases, the circumferential or partial annular reconstruction permitted secure implantation of the prosthetic valve. The one postoperative death was related to hemodialysis due to chronic renal failure. There were no other fatalities during the postoperative course, and the valves functioned normally. Our results suggest that this technique can be performed in high operative risk patients when mitral valve replacement is impossible using conventional techniques.
Background: Hospitalized elderly patients are often at risk of life-threatening infectious diseases such as pneumonia and urinary tract infection, thus diagnostic tools for bacterial infections are demanded. We developed a new predictive tool consolidating modified CURB-65, procalcitonin (PCT) and albumin (Alb). Method: This is a retrospective study. Modified CURB-65 (mCURB-65) score, PCT, Alb, and various cardiovascular/respiratory/renal functions were measured. Survival analyses were conducted to assess 30-days mortality of elderly patients using mCURB-65 score, PCT and Alb. The consolidated scores were compared with the number of patients died. Results: There were 445 elderly patients included. Kaplan–Meier survival curves showed significant differences between the high and low groups of mCURB-65, PCT and Alb (log-rank test, P < .001). Cox proportional regression showed that the hazard ratios (95% confidence intervals) for high mCURB-65, high Alb, and high PCT were all significant, 1.95 (1.24–3.05), 0.50 (0.32–0.77), and 2.09 (1.32–3.31), respectively. The consolidated scores showed tendency of increase with proportion of the number of patients died. Conclusions: The consolidated score consisted of mCURB-65, PCT and Alb can be a useful tool to predict short-term mortality of the hospitalized elderly patients with infectious disease.
We have long advocated the usefulness, accuracy and safety of carbon dioxide angiogrphy for patients with iodine allergy and renal dysfunction. In addition to its utility, no specialized apparatus is necessary for carbon dioxide angiography. Carbon dioxide as a contrast material has been adopted by consensus for use in endovascular revascularization. Here we report 4 cases of endovascular revascularization using carbon dioxide angiography. Two of the four patients had an iodine allergy, one had renal dysfunction, and the remaining one was complicated by diabetes mellitus. All patients exhibited intermittent claudication and were treated for iliac arterial stenotic lesions with percutaneous angioplasty and sequential endovascular stenting using carbon dioxide gas as a negative contrast material. All cases demonstrated improvement of the chief complaint. There were no direct or indirect complications of carbon dioxide angiography and endovascular intervention after the procedures. All 4 patients were discharged without event within 1 week after the endovascular intervention. Carbon dioxide is useful not only as an angiographic contrast material but also for endovascular intervention in patients with iodine allergy or renal dysfunction.
BackgroundThe introduction of biological agents, such as infliximab, which act against tumor necrosis factor-α was a major advance for the treatment of an increasing number of chronic diseases. Tumor necrosis factor-α antagonists represent a major therapeutic advance for the management of chronic inflammatory diseases, such as psoriasis. Previous studies have reported that the use of tumor necrosis factor-α antagonists increased the risk of opportunistic infections and reactivation of latent bacterial infections. Cardiac involvement, such as infective endocarditis, is very rare in the literature.Case presentationA 77-year-old Asian man with a 10-year history of psoriatic erythroderma was referred due to high fever and general malaise. He was treated with Predonine (prednisolone) and infliximab. After treatment, cardiac echography showed mitral valve vegetation and brain magnetic resonance imaging indicated multiple fresh infarctions. He died from large brain infarction in October 2013. An autopsy showed fresh thrombosis in his left middle cerebral artery, mitral valve vegetations, and septic micro-embolisms in multiple organs.ConclusionsLethal bacterial endocarditis was revealed after administration of tumor necrosis factor-α inhibitor, infliximab, for the treatment of psoriatic erythroderma. An autopsy showed vegetation in his mitral valve and brain infarction with fresh purulent embolism in his left middle cerebral artery and septic micro-embolisms.
