Pharmaceutical Prevention and Management of Cardiotoxicity in Hematological Malignancies.

Modern treatment modalities in hematology have improved clinical outcomes of patients with hematological malignancies. Nevertheless, many new or conventional anticancer drugs affect the cardiovascular system, resulting in various cardiac disorders, including left ventricular dysfunction, heart failure, arterial hypertension, myocardial ischemia, cardiac rhythm disturbances, and QTc prolongation on electrocardiograms. As these complications may jeopardize the significantly improved outcome of modern anticancer therapies, it is crucial to become familiar with all aspects of cardiotoxicity and provide appropriate care promptly to these patients. In addition, established and new drugs contribute to primary and secondary cardiovascular diseases prevention. This review focuses on the clinical manifestations, preventive strategies, and pharmaceutical management of cardiotoxicity in patients with hematologic malignancies undergoing anticancer drug therapy or hematopoietic stem cell transplantation.

Thromboprophylaxis in Patients with COVID-19: Systematic Review of National and International Clinical Guidance Reports.

BACKGROUND: Venous Thromboembolism (VTE) is common among patients with severe Coronavirus Disease 2019 (COVID-19). Anticoagulation in hospitalized COVID-19 patients has been associated with survival benefit; however, the optimal thromboprophylaxis strategy has not yet been defined. OBJECTIVE: To identify published guidance reports by national and international societies regarding thromboprophylaxis strategies in COVID-19 patients in different settings (outpatients, hospitalized, post-discharge). METHODS: A systematic review of the literature (Pubmed/EMBASE) was conducted independently by two investigators. RESULTS: Among 1942 initially identified articles, 33 guidance documents were included: 20 published by national and 13 by international societies. These documents provide recommendations mainly for hospitalized (97% of reports) and post-discharge (75%) COVID-19 patients, and less so for outpatients (34%). Thrombotic and bleeding risk stratification prior to any treatment decision is the cornerstone of all suggested thromboprophylaxis strategies; 81% of the documents recommend thromboprophylaxis for all hospitalized patients with a prophylactic dosage of low molecular weight heparin irrespective of VTE risk. Intermediate or therapeutic dose intensity is recommended in high VTE risk patients by 56% and 28% of documents, respectively. Mechanical thromboprophylaxis is suggested in case of high bleeding risk or contraindication to pharmacological thromboprophylaxis (59% of documents). Extended pharmacological thromboprophylaxis is recommended for patients with high VTE risk after hospital discharge (63% of documents). For non-hospitalized outpatients, 28% of documents recommend pharmacological thromboprophylaxis for high VTE risk. CONCLUSION: The current guidance identifies thromboprophylaxis in COVID-19 patients, especially during hospitalization, as of major importance for the prevention of VTE. Recommendations are derived from limited evidence from observational studies.

Clinical practice recommendations on the management of perioperative cardiac arrest: A report from the PERIOPCA Consortium.

BACKGROUND: Perioperative cardiac arrest is a rare complication with an incidence of around 1 in 1400 cases, but it carries a high burden of mortality reaching up to 70% at 30 days. Despite its specificities, guidelines for treatment of perioperative cardiac arrest are lacking. Gathering the available literature may improve quality of care and outcome of patients. METHODS: The PERIOPCA Task Force identified major clinical questions about the management of perioperative cardiac arrest and framed them into the therapy population [P], intervention [I], comparator [C], and outcome [O] (PICO) format. Systematic searches of PubMed, Embase, and the Cochrane Library for articles published until September 2020 were performed. Consensus-based treatment recommendations were created using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. The strength of consensus among the Task Force members about the recommendations was assessed through a modified Delphi consensus process. RESULTS: Twenty-two PICO questions were addressed, and the recommendations were validated in two Delphi rounds. A summary of evidence for each outcome is reported and accompanied by an overall assessment of the evidence to guide healthcare providers. CONCLUSIONS: The main limitations of our work lie in the scarcity of good quality evidence on this topic. Still, these recommendations provide a basis for decision making, as well as a guide for future research on perioperative cardiac arrest.

Nivolumab in patients with rare head and neck carcinomas: A single center's experience.

Immunotherapy (IO) with anti-PD1 inhibitors is available for the treatment of recurrent/metastatic squamous cell carcinomas of the head and neck (SCCHD) since 2016. Both nivolumab and pembrolizumab were tested in phase 3 randomized trials in adults progressing on or after platinum-based therapy and were found to confer an overall survival benefit compared to investigator's choice. However, very limited data exist concerning IO use in rare subtypes of head and neck carcinoma, like salivary gland carcinoma. We retrospectively collected clinical data of all patients diagnosed with rare subtypes of head and neck carcinoma, who were treated with immune checkpoint inhibitors in our department during the last 5 years. We analyzed safety and efficacy of these therapies. We identified six patients who received nivolumab for recurrent or metastatic head and neck carcinomas, between 31 and 57 years old. All patients had received at least one line of platinum-chemotherapy, as well as radiation therapy. Treatment was administered every 2 weeks, at a dose of 3 mg per kilogram of body weight. Number of nivolumab cycles varied between 2 and 18. Progression-free survival varied from 1 to 12 months and overall survival from 4 to 24 months. Tolerance was very good, except for one case of diabetes and hypothyroidism requiring medication. There is currently insufficient evidence regarding the optimal treatment of the rare non-squamous cell carcinoma of the head and neck. Our case series supports a role for immunotherapy in these patients. However, larger collaborative studies are needed to evaluate this treatment.
