Echevarria, K. Traugott","doi":"10.1002/phar.1892","DOIUrl":"https://doi.org/10.1002/phar.1892","url":null,"abstract":"Methicillin‐susceptible Staphylococcus aureus (MSSA) bacteremia is associated with high morbidity and mortality. Traditionally, antistaphylococcal penicillins (ASPs) have been considered the agents of choice for the treatment of MSSA bacteremia. Vancomycin has been demonstrated to have poorer outcomes in several studies and is only recommended for patients with severe penicillin allergies. Although cefazolin is considered as an alternative to the ASPs for patients with nonsevere penicillin allergies, cefazolin offers several pharmacologic advantages over ASPs, such as more convenient dosing regimens, and antimicrobial stewardship programs are increasingly using cefazolin as the preferential agent for MSSA infections as part of cost‐saving initiatives. Concerns about susceptibility to hydrolysis by type A β‐lactamases, particularly at high inocula seen in deep‐seated infections such as endocarditis; selective pressures from unnecessary gram‐negative coverage; and lack of comparative clinical data have precluded recommending cefazolin as a first‐line therapy for MSSA bacteremia. Recent clinical studies, however, have suggested similar clinical efficacy but better tolerability, with lower rates of discontinuation due to adverse drug reactions, of cefazolin compared with ASPs. Other variables, such as adequate source control (e.g., intravascular catheter removal, debridement, or drainage) and enhanced pharmacodynamics through aggressive cefazolin dosing, may mitigate the role of cefazolin inoculum effect and factor into determining improved clinical outcomes. In this review, we highlight the utility of cefazolin versus ASPs in the treatment of MSSA bacteremia with a focus on clinical efficacy and safety.","PeriodicalId":19812,"journal":{"name":"Pharmacotherapy: The Journal of Human Pharmacology and Drug Therapy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88664844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Treatment of Adults with Idiopathic Recurrent Pericarditis: Novel Use of Immunotherapy","authors":"N. Schwier, G. Hale, Marie L. Davies","doi":"10.1002/phar.1897","DOIUrl":"https://doi.org/10.1002/phar.1897","url":null,"abstract":"Idiopathic recurrent pericarditis (IRP) can be challenging to treat. Even after guideline‐directed first‐line treatment consisting of aspirin (ASA) or a nonsteroidal antiinflammatory drug (NSAID) in combination with colchicine therapy, recurrences still occur in greater than 20% of patients. Many patients then require treatment with long‐term corticosteroids, which is not a favorable option due to their short‐ and long‐term adverse effects. Because it is theorized that the pathophysiology of IRP may possess autoimmune sequelae, the use of immunotherapy for the treatment of IRP has emerged. In this review, we describe the literature associated with immunotherapy used to treat IRP in an adult population as well as provide an overview of the safety and monitoring parameters for each agent. The most common immunotherapies used after patients have had multiple recurrences of IRP are anakinra, intravenous immunoglobulin (IVIG), and azathioprine. In most cases, these immunotherapies are adjunctive therapy, with the goal of tapering and discontinuing immunosuppressive corticosteroids. After reviewing the data, anakinra resulted in more patients discontinuing corticosteroids and prevented further recurrences of pericarditis. IVIG resulted in symptom resolution and no further recurrences in most of the patients. Azathioprine was associated with more than half of patients becoming recurrence free; however, many patients required a restart of corticosteroids due to recurrence. Clinicians should be aware of the adverse effects of immunotherapy, ranging from mild gastrointestinal events to risk of infection and serious blood dyscrasias that may require diligent monitoring. The use of immunotherapy for the treatment of adults with IRP should be restricted to patients who have multiple recurrences. Ideally, immunotherapy would be adjunctive to first‐line combination therapy with ASA/NSAID plus colchicine, with the goal of tapering and discontinuing immunosuppressive corticosteroids. Furthermore, clinicians should consider cost, drug‐drug and drug‐disease interactions, and safety, as well as the quality of the retrospective evidence before considering any immunotherapy.","PeriodicalId":19812,"journal":{"name":"Pharmacotherapy: The Journal of Human Pharmacology and Drug Therapy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73800219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although melanoma is less common than basal cell and squamous cell skin cancers, melanoma is more dangerous because it is more likely to spread to other parts of the body, such as lymph nodes, if not diagnosed and treated early. Data from the National Cancer Institute indicate a steady rise in new cases of melanoma and, unfortunately, a steady rate in the number of deaths through 2013. Ninety percent of melanomas are linked to inadequate sun protection from ultraviolet rays or the tanning habits of young adults. Over the past 5 years, however, there have been a variety of new pharmacologic treatments for advanced melanoma including immunotherapy, targeted agents (BRAF and MEK inhibitors), and oncolytic viral therapy. In this article, we review the current literature on the treatment of melanoma, with a focus on emerging therapies.","PeriodicalId":19812,"journal":{"name":"Pharmacotherapy: The Journal of Human Pharmacology and Drug Therapy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85421383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Le","doi":"10.1002/phar.1899","DOIUrl":"https://doi.org/10.1002/phar.1899","url":null,"abstract":"Limited data exist for appropriate drug dosing in obese children. This comprehensive review summarizes pharmacokinetic (PK) alterations that occur with age and obesity, and these effects on antimicrobial dosing. A thorough comparison of different measures of body weight and specific antimicrobial agents including cefazolin, cefepime, ceftazidime, daptomycin, doripenem, gentamicin, linezolid, meropenem, piperacillin‐tazobactam, tobramycin, vancomycin, and voriconazole is presented. PubMed (1966–July 2015) and Cochrane Library searches were performed using these key terms: children, pharmacokinetic, obesity, overweight, body mass index, ideal body weight, lean body weight, body composition, and specific antimicrobial drugs. PK studies in obese children and, if necessary, data from adult studies were summarized. Knowledge of PK alterations stemming from physiologic changes that occur with age from the neonate to adolescent, as well as those that result from increased body fat, become an essential first step toward optimizing drug dosing in obese children. Excessive amounts of adipose tissue contribute significantly to body size, total body water content, and organ size and function that may modify drug distribution and clearance. PK studies that evaluated antimicrobial dosing primarily used total (or actual) body weight (TBW) for loading doses and TBW or adjusted body weight for maintenance doses, depending on the drugs’ properties and dosing units. PK studies in obese children are imperative to elucidate drug distribution, clearance, and, consequently, the dose required for effective therapy in these children. Future studies should evaluate the effects of both age and obesity on drug dosing because the incidence of obesity is increasing in pediatric patients.","PeriodicalId":19812,"journal":{"name":"Pharmacotherapy: The Journal of Human Pharmacology and Drug Therapy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90303569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Early clinical trials with autologous anti‐CD19 chimeric antigen receptor (CAR) T cells have demonstrated promising results for patients who have relapsed or refractory disease. Lymphodepleting conditioning regimens, including cyclophosphamide, fludarabine, pentostatin, bendamustine, interleukin‐2, and total body irradiation, are often administered before the infusion of CAR T cells, allowing for greater T‐cell expansion. The major toxicity associated with CAR T‐cell infusions is cytokine release syndrome (CRS), a potentially life‐threatening systemic inflammatory disorder. The quick onset and progression of CRS require rapid detection and intervention to reduce treatment‐related mortality. Management with tocilizumab can help ameliorate the symptoms of severe CRS, allowing steroids, which diminish the expansion and persistence of CAR T cells, to be reserved for tocilizumab‐refractory patients. Other toxicities of CAR T‐cell therapy include neutropenia and/or febrile neutropenia, infection, tumor lysis syndrome, neurotoxicity and nausea/vomiting. A review of patients’ medications is imperative to eliminate medications that may contribute to treatment‐related toxicities. Studies are ongoing to help optimize patient selection, preparation, safety, and management of individuals receiving CAR T cells. Long‐term follow‐up will help establish the place of CAR T cells in therapy.","PeriodicalId":19812,"journal":{"name":"Pharmacotherapy: The Journal of Human Pharmacology and Drug Therapy","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81151595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
