The Annals of pharmacotherapy

To report a case of successful use of prasugrel following percutaneous coronary intervention with placement of a bare metal stent in a patient with a documented hypersensitivity reaction to clopidogrel. ⋯ Prasugrel may be considered a therapeutic alternative in some patients allergic or intolerant to clopidogrel, but additional data are warranted to make a strong conclusion.

Antipyretic therapy is commonly prescribed for patients with infection, but studies of its impact on clinical outcomes have yielded mixed results. No data exist to characterize the use of antipyretic medications in patients with severe sepsis or septic shock. ⋯ Most febrile episodes in patients with gram-negative severe sepsis or septic shock were not treated with antipyretic medications. Further studies are needed to demonstrate the effect of antipyretics on clinically relevant outcomes in severe sepsis and septic shock.

Intravenous bisphosphonate therapy has been linked to osteo-necrosis of the jaw among patients with cancer. Some patients with osteoporosis also receive intravenous bisphosphonates, although at lower total doses than those with cancer. ⋯ Patients with osteoporosis who are treated with intravenous bisphosphonates do not appear to have a statistically significant increase in the incidence of osteonecrosis of the jaw over 3 years compared with those who do not receive such treatment. Future studies will further contribute to our understanding of the bisphosphonate risk profile, thereby allowing patients and physicians to more rigorously assess the risk-benefit ratio of this treatment across different clinical scenarios.

Optimization of the timing of appropriate antibiotics is crucial to improve the management of patients in severe sepsis and septic shock. Vancomycin is commonly used empirically in cases of nosocomial infections in critically ill patients. Therefore, early optimization of vancomycin pharmacokinetics is likely to improve outcomes. ⋯ The MM-USCPACK program is a useful and reliable tool for prediction of serum vancomycin concentrations in patients hospitalized in ICU and likely reflects the close monitoring of renal function in this setting. For some patients (more severely ill, obese, or significant change in renal function during vancomycin therapy), predictions were less precise.

Comparative Study
Bivalirudin dosing adjustments for reduced renal function with or without hemodialysis in the management of heparin-induced thrombocytopenia.
While not approved by the Food and Drug Administration for treatment of heparin-induced thrombocytopenia (HIT), except in patients undergoing percutaneous interventions, the direct thrombin inhibitor bivalirudin is a treatment option that is gaining use. An initial dose of bivalirudin 0.15-0.2 mg/kg/h, adjusted to an activated partial thromboplastin time (aPTT) of 1.5-2.5 times the baseline value, has been suggested. Initial dosing in patients with renal dysfunction, including those on hemodialysis, is unclear. ⋯ Patients with renal dysfunction require a reduced dose of bivalirudin to reach a therapeutic aPTT goal. Slightly higher doses may be observed in patients receiving hemodialysis.
