Pharmacological Management of Atypical Hemolytic Uremic Syndrome in Pediatric Patients: Current and Future.
Atypical hemolytic uremic syndrome is a thrombotic microangiopathy characterized by hemolysis, thrombocytopenia, and acute kidney injury, usually caused by alternative complement system overactivation due to pathogenic genetic variants or antibodies to components or regulatory factors in this pathway. Previously, a lack of effective treatment for this condition was associated with mortality, end-stage kidney disease, and the risk of disease recurrence after kidney transplantation. Plasma therapy has been used for atypical hemolytic uremic syndrome treatment with inconsistent results. Complement-blocking treatment changed the outcome and prognosis of patients with atypical hemolytic uremic syndrome. Early administration of eculizumab, a monoclonal C5 antibody, leads to improvements in hematologic, kidney, and systemic manifestations in patients with atypical hemolytic uremic syndrome, even with apparent dialysis dependency. Pre- and post-transplant use of eculizumab is effective in the prevention of atypical hemolytic uremic syndrome recurrence. Evidence on eculizumab use in secondary hemolytic uremic syndrome cases is controversial. Recent data favor the restrictive use of eculizumab in carefully selected atypical hemolytic uremic syndrome cases, but close monitoring for relapse after drug discontinuation is emphasized. Prophylaxis for meningococcal infection is important. The long-acting C5 monoclonal antibody ravulizumab is now approved for atypical hemolytic uremic syndrome treatment, enabling a reduction in the dosing frequency and improving the quality of life in patients with atypical hemolytic uremic syndrome. New strategies for additional and novel complement blockage medications in atypical hemolytic uremic syndrome are under investigation.
期刊介绍:
Pediatric Drugs promotes the optimization and advancement of all aspects of pharmacotherapy for healthcare professionals interested in pediatric drug therapy (including vaccines). The program of review and original research articles provides healthcare decision makers with clinically applicable knowledge on issues relevant to drug therapy in all areas of neonatology and the care of children and adolescents. The Journal includes:
-overviews of contentious or emerging issues.
-comprehensive narrative reviews of topics relating to the effective and safe management of drug therapy through all stages of pediatric development.
-practical reviews covering optimum drug management of specific clinical situations.
-systematic reviews that collate empirical evidence to answer a specific research question, using explicit, systematic methods as outlined by the PRISMA statement.
-Adis Drug Reviews of the properties and place in therapy of both newer and established drugs in the pediatric population.
-original research articles reporting the results of well-designed studies with a strong link to clinical practice, such as clinical pharmacodynamic and pharmacokinetic studies, clinical trials, meta-analyses, outcomes research, and pharmacoeconomic and pharmacoepidemiological studies.
Additional digital features (including animated abstracts, video abstracts, slide decks, audio slides, instructional videos, infographics, podcasts and animations) can be published with articles; these are designed to increase the visibility, readership and educational value of the journal’s content. In addition, articles published in Pediatric Drugs may be accompanied by plain language summaries to assist readers who have some knowledge of, but not in-depth expertise in, the area to understand important medical advances.
