Fluconazole, voriconazole, and itraconazole may potentiate the hypercalcemic effect of other medications, although to date, triazoles alone have not been linked to hypercalcemia. We describe a case of new-onset hypercalcemia in the setting of high-dose fluconazole that resolved after changing the antifungal regimen. We reviewed our institutional database to assess the frequency of moderate or s...

BACKGROUND Dipeptidyl peptidase-4 (DPP-4) inhibitors are novel classified oral anti-diabetic drugs for the treatment of type 2 diabetes mellitus (T2DM) that provide important reduction in glycated hemoglobin, with a low risk for hypoglycemia and no weight gain. In T2DM patients with reduced renal function, adequate glycemic control is essential to delay the progress of kidney dysfunction, but t...

The protection and immune response to infection caused by the parasite Schistosoma mansoni were studied by comparison of two murine irradiated-vaccine models. Mice were exposed from 1 to 4 times to infective-stage cercariae attenuated with either a moderate dose (15 kilorads) or a high dose (50 kilorads) of radiation. Seven weeks after challenge infection, the mice were assessed for resistance,...

introduction:  asthma exacerbation is common in children. treatment with oral corticosteroids (ocs) and inhaled corticosteroids are suggested for asthma exacerbation. it is shown that inhaled corticosteroids has similar outcome in reducing asthma symptoms compared to ocs. but few studies have evaluated the pulmonary function changes in these two treatments. in this study, we evaluated the chang...

Low-density lipoprotein cholesterol (LDL-C) reductions with the PCSK9 monoclonal antibody alirocumab may be affected by background statin dose due to increased PCSK9 levels with higher statin doses. Data from 8 Phase 3 trials conducted with background statin (n = 4629) were pooled by alirocumab dose (75 or 150 mg every 2 weeks) and control (placebo/ezetimibe), and analyzed by background statin ...
