Addressing Inpatient Beta-Lactam Allergies: A Multihospital Implementation.

Addressing inaccurate penicillin allergies is encouraged as part of antibiotic stewardship in the inpatient setting. However, implementing interventions targeted at the 10% to 15% of inpatients reporting a previous penicillin allergy can pose substantial logistic challenges. We implemented a computerized guideline for patients with reported beta-lactam allergy at 5 hospitals within a single health care system in the Boston area. In this article, we describe our implementation roadmap, including both successes achieved and challenges faced. We explain key implementation steps, including assembling a team, stakeholder engagement, developing or selecting an approach, spreading the change, establishing measures, and measuring impact. The objective was to detail the lessons learned while empowering others to be part of this important, multidisciplinary work to improve the care of patients with reported beta-lactam allergies.

Pharmacotherapy prevention and management of nutritional deficiencies post Roux-en-Y gastric bypass.

Roux-en-Y gastric bypass is the most commonly performed bariatric procedure. It is associated with nutritional deficiencies due to gastric reduction, intestinal bypass, reduced caloric intake, avoidance of nutrient-rich foods, noncompliance with supplementation and poor food tolerability. Although there are multiple publications on this topic, there is a lack of consistent guidance for the healthcare practitioner caring for the bariatric patient. This article will encompass literature reviewing the pharmacotherapy approach to prevention and management of nutritional deficiencies since the American Society of Metabolic and Bariatric Surgery guidelines were published in 2008.

Maintenance immunosuppression with intermittent intravenous IL-2 receptor antibody therapy in renal transplant recipients.

OBJECTIVE: To report what we believe to be the first 2 cases of long-term (>24 months) intermittent intravenous interleukin-2 receptor antibody (IL-2RA) therapy for maintenance immunosuppression following renal transplantation. CASE SUMMARY: The first patient is a 52-year-old female with a history of intolerance to calcineurin inhibitors (CNIs) and sirolimus. Following her second transplant, the patient received mycophenolate mofetil 100 mg twice daily, a tapering corticosteroid regimen (initial dose of methylprednisolone 500 mg tapered over 1 week to prednisone 30 mg/day), and biweekly intravenous daclizumab 1-1.2 mg/kg/dose; 33 months after transplant the IL-2RA was changed to intravenous basiliximab 40 mg once a month. At 40 months after transplant, the patient continued to have stable renal function (estimated glomerular filtration rate 48 mL/min/1.73 m²) with excellent tolerability. The second patient is a 59-year-old female also intolerant to CNIs and sirolimus who required intermittent maintenance therapy with intravenous basiliximab 20 mg/dose. Despite an initial rejection episode, the patient tolerated more than 2 years of basiliximab therapy with good renal function (estimated glomerular filtration rate 103 months after transplant 69 mL/min/1.73 m²) and no adverse events. DISCUSSION: The IL-2RAs basiliximab and daclizumab possess several characteristics of ideal maintenance immunosuppressive agents (ie, nondepleting, long half-lives, limited adverse events). Based on a MEDLINE search (through December 31, 2010) using the search terms basiliximab, daclizumab, organ transplant, immunosuppression, and/or maintenance immunosuppression, and an advanced search in the published abstracts from the American Transplant Congress and World Transplant Congress (2000-2010), it appears that IL-2RAs have been used successfully as short-term therapy in both renal and extrarenal transplant recipients to allow for renal recovery following CNI-induced nephrotoxicity. In heart transplant recipients, the IL-2RAs have been used for <24 months as maintenance immunosuppression in patients intolerant of CNIs or sirolimus. CONCLUSIONS: To the best of our knowledge, these 2 cases are the first to demonstrate that IL-2RAs can be used as an alternative to a CNI in a de novo immunosuppressive regimen. Also, this is the first report to illustrate successful long-term use of IL-2RAs in renal transplant recipients. This alternative approach was well tolerated by our patients, with no apparent adverse events. Although the efficacy of such regimens cannot be determined with 2 case reports, the fact that intermittent intravenous IL-2RA administration was successfully accomplished in these patients provides impetus to evaluate this treatment modality in prospective studies.

Bariatric surgery pharmacy consultation service.

Bariatric surgical patients often need changes in formulation and dosages of their medications. The literature contains minimal information regarding pharmaceutical care and consultation services for the bariatric surgery patient. Complex medication regimens and safety concerns initiated a collaborative effort between surgeons and pharmacists to manage more effectively bariatric patients perioperatively. The consultation service included patient identification, pharmacy referral, pharmacist consultation with the patient, communication of recommendations with surgeons, follow-up, and documentation. There were 124 consultations performed from February 2, 2009 to December 1, 2010 with an average of 7.7 medications optimized per patient. Every patient required a minimum of one adjustment to their regimen. The surgeons approved 98% of these recommendations. Of recommendations provided, the majority focused on changing the formulation of the medication in some manner. The collaborative effort between surgeons and pharmacists effected changes in medication transitioning perioperatively and resulted in improved pharmaceutical care for this patient population.

Dronedarone: a review of characteristics and clinical data.

Atrial fibrillation (AF) is a common arrhythmia associated with increased cardiovascular mortality, stroke, and hospitalization in the United States. Amiodarone is generally considered as the agent with the best efficacy for maintaining normal sinus rhythm. Despite its efficacy, amiodarone use is often limited by its extensive side effect profile. Dronedarone is a noniodinated benzofuran derivative of amiodarone that has been recently approved by the Food and Drug Administration to reduce cardiovascular hospitalization in patients with AF or atrial flutter. Structural modification of dronedarone was introduced to shorten the half-life, decrease lipophilicity, and minimize noncardiovascular toxicity as compared to amiodarone. This article reviews the pharmacology, adverse effects, and clinical evidence available to date of the use of dronedarone in the management of AF.
