Thrombotic thrombocytopenic purpura after prophylactic cefuroxime axetil administered in relation to a liposuction procedure

De-novo immune-mediated thrombotic thrombocytopenic purpura following surgical and non-surgical procedures: A systematic review

When de-novo immune-mediated thrombotic thrombocytopenic purpura (TTP) is diagnosed following an invasive procedure, clinical presentation patterns and outcomes are poorly defined. Therefore, in a systematic literature review of patients diagnosed with TTP following an invasive surgical or non-surgical procedure, we identified 19 studies reporting data on 25 patients. These data suggest that 1) TTP pathogenesis likely begins prior to the invasive procedure, 2) patients experience significant diagnostic delays, and 3) there is a high incidence of renal replacement therapy. Although invasive procedures may trigger TTP, further studies are needed to clarify the mechanisms underlying this association.

Ceftriaxone-Induced Thrombotic Thrombocytopenic Purpura Treated Successfully With Plasmapheresis and Eculizumab: A Rare Case Report

Thrombotic Thrombocytopenic Purpura (TTP) is a subtype of thrombotic microangiopathy (TMA) resulting in thrombocytopenia, anemia, fever, renal and neurological deficits. Although many drugs have been associated with drug-induced TTP, ceftriaxone has never been reported. Our case reports a patient who was started on ceftriaxone and developed TTP. Peripheral smear showed schistocytes and thrombocytopenia. Surprisingly, antibody formation against the metalloproteinase (ADAMTS13) levels were low-normal. The patient was treated with plasmapheresis and eczulimab, leading to platelet recovery and symptom resolution. TTP is a rare disorder and can be acquired or idiopathic. TTP can be diagnosed with normal ADAMTS13 as well. Further research is required to assess the mechanism by which ceftriaxone causes TTP. Physicians should consider the possibility of TTP in patients with similar presentations following ceftriaxone therapy and use it for timely diagnosis and treatment. Early diagnosis and treatment of ceftriaxone-induced TTP can prevent devastating consequences.

Acute thrombocytopenia during cesarean section

We report a case of a healthy 29-year-old parturient with a normal pre-operative platelet count who received combined spinal-epidural anesthesia for cesarean section, and who suffered the sudden intra-operative onset of severe thrombocytopenia (platelet count 3 × 10⁹/L). This event was likely due to cefoxitin administered for the prophylaxis of surgical infection.

Thrombotic thrombocytopenic purpura in a postoperative patient taking cephalexin responding to plasmapheresis: A case report and review of cephalosporin-induced TTP

The clinical presentation of thrombotic thrombocytopenic purpura (TTP) is often atypical delaying diagnosis and treatment. A number of drugs have been implicated in the development of TTP, including cyclosporine, tacrolimus, clopidogrel, and quinine. To our knowledge, only three cases of cephalosporin-induced TTP have been described, with two of these cases occurring with these use of cephalexin. We herein describe a case of TTP occurring in a postoperative patient taking cephalexin, requiring plasmapheresis. Following plasmapheresis, the patient's mental status and platelet count significantly improved. J. Clin. Apheresis 31:473-475, 2016. © 2015 Wiley Periodicals, Inc.

Postoperative thrombotic thrombocytopenic purpura

Thrombotic thrombocytopenic purpura (TTP) is a rare, life-threatening disease characterized by acute episodes of thrombocytopenia and microangiopathic hemolytic anemia occurring due to platelet and von Willebrand factor deposition and hyaline thrombi formation in arterioles and capillaries throughout the body, which results in organ ischemia. TTP can be idiopathic or secondary, and there are several causes of secondary TTP. There is a clinical syndrome resembling TTP that occurs after surgical procedures, so-called "postoperative TTP" (pTTP). In this review, the differential diagnosis, pathogenesis and clinical and laboratory features of pTTP, together with the treatment modalities and outcomes of the patients, are discussed. The pTTP is a diagnosis of exclusion, and disseminated intravascular coagulation, heparin-induced thrombocytopenia and medication-induced effects should be ruled out. As in classical TTP, patients with pTTP should be diagnosed and treated with therapeutic plasma exchange (TPE) as early as possible to reduce their morbidity and mortality. Although rarely seen, surgeons and physicians of all specialties should be alert to the possibility of pTTP, and since pTTP is a life-threatening event that usually can be treated successfully with TPE, especially when diagnosed early in its course, it is critical to recognize and treat pTTP promptly.
