Heparin-induced thrombocytopenia in the pediatric population: a review of current literature
Review published in J Pediatr Pharmacol Ther (2012)
Abstract
Heparin-induced thrombocytopenia is a rare and serious reaction to unfractionated heparin and low-molecular-weight heparins in children. Quick recognition, discontinuation of heparin, and subsequent treatment with an alternative anticoagulant are essential steps to prevent serious complications such as thrombus and limb amputation. The purpose of this review is to describe the clinical features of heparin-induced thrombocytopenia in children and to summarize the data available for its management. This paper summarizes data and relates the use of direct thrombin inhibitors with clinical outcomes. A literature search was conducted with Ovid, using the key terms argatroban, bivalirudin, hirulog, danaparoid, lepirudin, direct thrombin inhibitor, heparin-induced thrombocytopenia, thrombosis, warfarin, and fondaparinux. Articles were excluded if they were classified as editorials, review articles, or conference abstracts or if they involved patients 18 years of age or older or described disease states not related to thrombosis. Nineteen articles containing 33 case reports were identified and evaluated for this review. Of the 33 cases, 14, 10, 4, and 2 cases described the use of lepirudin, danaparoid, argatroban, and bivalirudin, respectively. Two cases did not report the type of anticoagulant used, and 1 case used aspirin. The most commonly reported complication was bleeding.

Resumen
Review of 33 pediatric HIT case reports across 19 articles; lepirudin used in 14 cases, danaparoid in 10, argatroban in 4 and bivalirudin in 2, all leech-derived DTIs feature prominently.
Por qué esto importa para la hirudoterapia
This review summarizes clinical features and management data for heparin-induced thrombocytopenia (HIT) in the pediatric population, identifying 33 case reports across nineteen articles and evaluating alternative anticoagulants including direct thrombin inhibitors. Of the 33 cases, lepirudin was the most frequently reported agent (14 cases), followed by danaparoid (10), argatroban (4), and bivalirudin (2), with bleeding as the most commonly reported complication. While lepirudin appears prominently in this pediatric case series, the abstract does not describe its origin, mechanism, or any connection to leeches or hirudotherapy. No defensible leech link can be drawn from the abstract alone; the article is focused on HIT management in children.
