Should immunologic strategies be incorporated into frontline ALL therapy?

Survival rates in adult patients with acute lymphoblastic leukemia (ALL) have markedly improved during the past decade. The one-size-fits-all-ages approach has been replaced with adaptation of pediatric-inspired treatment protocols for younger adults. Yet different treatment strategies for older patients are needed due to chemotherapy-related toxicities. A new era of immunotherapy has arrived, offering opportunities for targeted treatments for ALL subtypes. While CD20 targeting with rituximab has been demonstrated to improve survival when combined with chemotherapy, it has little activity as a single agent in ALL. In contrast, antibody targeting of CD19 and CD22 with blinatumomab and inotuzumab ozogamicin, respectively, has had remarkable single-agent activity in the relapsed setting. Studies are now underway to test these agents in combination with chemotherapy in the frontline setting. The goal of these studies is to improve event-free survival and overall survival by using these approaches in the frontline to eradicate minimal residual disease and, particularly in older adults with ALL, to reduce treatment-related toxicity by limiting the exposure to traditional multi-agent chemotherapy with its attendant toxicities. This review focuses on new immunotherapeutic treatment options and strategies for frontline treatment, including a brief discussion of the use of true immunotherapy, chimeric antigen receptor T-cells, for relapsed B-cell ALL, the potential for targeting CD38 in T-cell ALL, and how these approaches are facilitating the next steps to improve survival for adult patients with ALL.     

Should statins be part of the treatment of heart failure?

Beyond their lipid lowering properties HMG-CoA reductase inhibitors (statins) have numerous effects in the cardiovascular system. Commonly referred as "pleiotropic properties", these properties could justify the use of statins in the treatment of congestive heart failure. Excluding the beneficial effects of statins related to the prevention of coronary ischemic events, this review focuses on the emerging mechanisms which may explain the therapeutic potential of satins in heart failure, particularly their action on endothelial function, myocardial and renal energetic metabolism, inflammation, thrombosis, oxidative stress, ventricular remodeling and hypertrophy, and renal function.     

Should management of pneumonia be an indicator of quality of care?

Many regulatory bodies and payers measure the quality of care provided to patients admitted to the hospital with pneumonia. Some pneumonia quality measures were not based on high-level evidence, and there is also concern that public reporting of performance could drive excessive use of diagnostic testing and antibiotic treatment. There have been significant increases in the performance rate of several process of care recommended for patients hospitalized with pneumonia, accompanied by a decrease in 30-day mortality. To maximize the potential for improved patient outcomes, physicians and regulators must remain vigilant to detect unintended negative consequences related to performance measurement.     

Should hepatitis B vaccination be introduced into childhood immunisation programmes in northern Europe?

Infection with hepatitis B causes between 500,000 and 1.2 million deaths per year worldwide, and is the leading cause of liver cancer. Over 12 years ago, WHO recommended that universal childhood hepatitis B vaccination be implemented globally. Despite this, Denmark, Finland, Iceland, Ireland, the Netherlands, Norway, Sweden, and the UK have yet to implement such a policy and instead currently adopt an "at-risk" strategy. Although all eight countries are classed as having low endemicity, factors such as increased travel and integration of immigrant communities are increasing the number of at-risk individuals in these countries. Considering the difficulty in identifying all at-risk individuals, and the lack of effectiveness of at-risk vaccination on reducing the overall incidence of hepatitis B, we recommend that these countries reassess their hepatitis B prevention strategies. Universal vaccination against hepatitis B is the only way to eliminate the major public-health impact of this disease.
