Bevacizumab-associated thrombotic microangiopathy treated with eculizumab: A case series and systematic review of the literature.

BACKGROUND: Bevacizumab is a recombinant monoclonal antibody against the vascular endothelial growth factor A (VEGF-A) ligand that is used in the management of various solid malignancies. The adverse effect profiles of angiogenesis inhibitors, such as bevacizumab, have become increasingly well characterized and include renal manifestations such as hypertension, proteinuria, and thrombotic microangiopathy. Eculizumab inhibits terminal-complement activation and is used to treat atypical hemolytic uremic syndrome. There has been growing usage of eculizumab to treat bevacizumab-associated thrombotic microangiopathy. MATERIALS AND METHODS: We performed a systematic review of the literature to identify full-text articles that describe the use of eculizumab for bevacizumab-associated thrombotic microangiopathy. RESULTS: Our systematic review identified 522 unique articles of which 5 were included in the final review. 9 cases, including 2 new cases presented in this review, were identified in which eculizumab was used in the management of bevacizumab-associated thrombotic microangiopathy. Hematologic parameters and kidney function stabilized or improved in all cases, and the 2 patients who required renal replacement therapy were able to discontinue dialysis. CONCLUSIONS: Given the findings of this systematic review, the use of eculizumab in the treatment of bevacizumab-associated thrombotic microangiopathy warrants further study, particularly in severe cases.

Parent Coping Support Interventions During Acute Pediatric Hospitalizations: A Meta-Analysis.

CONTEXT: Parents may experience psychological distress when a child is acutely hospitalized, which can negatively affect child outcomes. Interventions designed to support parents' coping have the potential to mitigate this distress. OBJECTIVE: To describe interventions designed to provide coping support to parents of hospitalized children and conduct a meta-analysis of coping support intervention outcomes (parent anxiety, depression, and stress). DATA SOURCES: We searched Pubmed, Embase, PsycINFO, Psychiatry Online, and Cumulative Index to Nursing and Allied Health Literature from 1985 to 2016 for English-language articles including the concepts "pediatric," "hospitalization," "parents," and "coping support intervention." STUDY SELECTION: Two authors reviewed titles and abstracts to identify studies meeting inclusion criteria and reviewed full text if a determination was not possible using the title and abstract. References of studies meeting inclusion criteria were reviewed to identify additional articles for inclusion. DATA EXTRACTION: Two authors abstracted data and assessed risk of bias by using a structured instrument. RESULTS: Initial searches yielded 3450 abstracts for possible inclusion. Thirty-two studies met criteria for inclusion in the systematic review and 12 studies met criteria for inclusion in the meta-analysis. The most commonly measured outcomes were parent depression, anxiety, and stress symptoms. In meta-analysis, combined intervention effects significantly reduced parent anxiety and stress but not depression. Heterogeneity among included studies was high. LIMITATIONS: Most included studies were conducted at single centers with small sample sizes. CONCLUSIONS: Coping support interventions can alleviate parents' psychological distress during children's hospitalization. More evidence is needed to determine if such interventions benefit children.
