The incidence of heparin-induced thrombocytopenia in medical patients treated with low-molecular-weight heparin: a prospective cohort study.
2005
AbstractIn contrast with extensive documentation in patients treated with unfractionated heparin (UFH), the incidence of heparin-induced thrombocytopenia (HIT) in medical patients receiving low-molecular-weight heparin (LMWH) is less well defined. In a prospective cohort study, the platelet count was monitored in 1754 consecutive patients referred to 17 medical centers and treated with LMWH for prophylaxis or treatment of thromboembolic disorders. The diagnosis of HIT was accepted in case of a platelet drop of at least 50%, the absence of obvious explanations for thrombocytopenia, and the demonstration of heparin-dependent IgG antibodies. HIT developed in 14 patients (0.80%; 95% CI, 0.43%-1…
Successful management of heparin-induced thrombocytopenia using argatroban in a very old woman: a case report.
2012
Thrombosis due to heparin-induced thrombocytopenia (HIT) is rare but has a severe prognosis. Its management is not always easy, particularly in old patients with renal insufficiency. A 95-year-old woman was hospitalized for dyspnea. Curative treatment with unfractionated heparin was started because pulmonary embolism was suspected. Disseminated intravascular coagulation was then suspected because of thrombocytopenia, hypoprothrombinemia, hypofibrinogenemia, and a positive ethanol gelation test. The first immunoassay for HIT was negative. On the 12th day of hospitalization, bilateral cyanosis of the toes occurred associated with recent deep bilateral venous and arterial thrombosis at duplex …

Recurrent venous thromboembolism complicated by heparin-induced thrombocytopenia as a first manifestation of an occult cancer: a case report.
2008
Heparin-Induced Trombocytopenia (HIT) is a serious and potentially fatal complication of patients on heparins. Its management is difficult and it can be more complicated in patients with cancer because of the hemorrhagic risk carried out by direct inhibitor of thrombin, the currently approved drug for HIT. At present, it is not clear whether cancer patients also have an increased risk of HIT. We describe the case of a patient with occult cancer at the moment of the index venous thrombosis, who developed Deep Vein Thrombosis (DVT) and concomitant HIT with thrombotic complications (recurrent contralateral venous thrombosis). The management of HIT was efficaciously based on the combined use o…
Diagnosis of Heparin-Induced Thrombocytopenia: Development and Validation of a Predictive Clinical Score Based on Objective Features Identified by a …
2019
Background: Diagnosis of heparin-induced thrombocytopenia (HIT) is based on a composite of clinical likelihood and laboratory testing. We aimed to develop a diagnostic score derived from multivariate analysis of clinical features, including platelet count changes, prospectively recorded in patients with suspected HIT. Methods: This multinational observational study (ClinicalTrials.gov no. NCT00748839) included 2280 adult patients with suspected HIT: 1597 (derivation cohort) formed the basis for developing the scoring system, subsequently validated in 683 additional randomly selected patients (validation cohort). HIT was diagnosed by two independent adjudicators based on clinical features, l…
Quantitative and Qualitative Platelet Derangements in Cardiac Surgery and Extracorporeal Life Support
2021
Thrombocytopenia and impaired platelet function are known as intrinsic drawbacks of cardiac surgery and extracorporeal life supports (ECLS). A number of different factors influence platelet count and function including the inflammatory response to a cardiopulmonary bypass (CPB) or to ECLS, hemodilution, hypothermia, mechanical damage and preoperative treatment with platelet-inhibiting agents. Moreover, although underestimated, heparin-induced thrombocytopenia is still a hiccup in the perioperative management of cardiac surgical and, above all, ECLS patients. Moreover, recent investigations have highlighted how platelet disorders also affect patients undergoing biological prosthesis implanta…
Anticoagulation in a Neurosurgical Patient with Heparin-Induced Thrombocytopenia Type II with Argatroban and Fondaparinux after Clipping of an Intrac…

Background: Therapeutic anticoagulation in patients after a major neurosurgical procedure remains critical because of the risk of a major intracranial bleed. Novel drugs could play
