OBJECTIVE: New therapeutic agents in combination with the standard Stupp protocol (a protocol about the temozolomide combined with radiotherapy treatment with glioblastoma was research by Stupp R in 2005) were assessed to evaluate whether they were superior to the Stupp protocol alone, to determine the optimum treatment regimen for patients with newly diagnosed glioblastoma. PATIENTS AND METHODS: We implemented a search strategy to identify studies in the following databases: PubMed, Cochrane Library, EMBASE, CNKI, CBM, Wanfang, and VIP, and assessed the quality of extracted data from the trials included...

BACKGROUND: The aim of this study was to evaluate effects of Shen-Cao granules for the prevention of thrombocytopenia caused by anticancer chemotherapy. METHODS: In this prospective study, a total of 200 patients with various malignant tumors were enrolled and evenly divided into a Shen-Cao granule treatment (n = 100) and a control group (n = 100). After 2 cycles chemotherapy with any combination of platinum-based drugs (cisplatin, carboplatin, and nedaplatin), the blood platelet (PLT) counts, levels of the PLT production regulator thrombopoietin (TPO), PLT aggregation rates, and the PLT activation marker CD62P expressions were monitored for 2 weeks...

Adverse reactions of subcutaneous low molecular weight heparin or unfractionated heparin could be complications by bleeding, heparin-induced thrombocytopenia, drug-induced liver injury, osteoporosis, and cutaneous reactions. Heparin-induced skin lesions vary from allergic reactions like erythema, urticaria, eczema to intradermal microvascular thrombosis associated with heparin-induced thrombocytopenia. There is a rare cutaneous complication, called bullous hemorrhagic dermatosis. We experienced this rare case of the cutaneous complication caused by enoxaparin...

A 43-year-old incarcerated man with AIDS was hospitalized for 30 pounds weight loss and diffuse pruritic rash. Three months prior, he was started on dapsone for Pneumocystis jiroveci pneumonia prevention. Biochemical evaluation was remarkable for eosinophilia, thrombocytopenia, acute renal insufficiency, transaminitis, thyrotoxicosis, and significant hyperglycemia (450 mg/dl; nl, 65-99). His hemoglobin A1c level was 5.9% (nl, 4.1-5.6). Thyroid-stimulating immunoglobulin, glutamic acid decarboxylase, and islet cell autoantibodies were within the normal range...

BACKGROUND: Heparin-induced thrombocytopenia (HIT) is an adverse drug reaction presenting as a prothrombotic disorder related to antibody-mediated platelet activation. It is a paradoxical immune reaction resulting in thrombin generation in vivo, which leads to a hypercoagulable state and the potential to initiate venous or arterial thrombosis. A number of factors are thought to influence the incidence of HIT including the type and preparation of heparin (unfractionated heparin (UFH) or low molecular weight heparin (LMWH)) and the heparin-exposed patient population, with the postoperative patient population at higher risk...

Gemcitabine is a chemotherapy drug. It is a nucleoside analogue that is usually well tolerated by patients, with myelosuppression (especially thrombocytopenia) as dose-limiting side effect. Other mild to moderate side effects include alopecia, vomiting, nausea, rash, and fever. Coronary ischemia is the most common cardiotoxic effect of gemcitabine, which is due to its antimetabolites. While underlying cause of coronary ischemia following use of gemcitabine is uncertain, endothelial dysfunction and coronary thrombosis are potential explanations...

Drug-induced immune thrombocytopenia (D-ITP) typically occurs after the patient has been receiving the implicated drug for at least 1 week, due to newly forming drug-dependent antibodies ("typical-onset" D-ITP). A "rapid-onset" form of D-ITP can occur when previous sensitization has occurred, where antibodies have thus already been formed, and a precipitous platelet count fall occurs upon reexposure. Typical-onset D-ITP has been reported after levofloxacin, but the rapid-onset form with a well-documented previous exposure has not been described...

Drug-induced thrombocytopenia can be caused by various medications, most frequently, antibiotics. There have been reports of thrombocytopenia cases due to the usage of quinolone antibiotics, although moxifloxacin-related thrombocytopenia has been reported very rarely. The case is here presented of a 60-year old male with chronic obstructive pulmonary disease who presented with complaints of progressively worsening dyspnea. After hospitalization, progressive thrombocytopenia was detected which had started on the 3rd day of moxifloxacin treatment...

BACKGROUND: Heparin-induced thrombocytopenia (HIT) is a prothrombotic drug reaction caused by platelet-activating anti-PF4/heparin antibodies. Given time-sensitive treatment considerations, a rapid and accurate laboratory test for HIT antibodies is needed. AIMS: To determine operating characteristics for the HemosIL(®) HIT-Ab(PF4/H), a rapid, on-demand, fully-automated, latex immunoturbidimetric assay (LIA), for diagnosis of HIT. METHODS: We evaluated LIA sensitivity, specificity, negative (NPV) and positive predictive value (PPV), negative (LR-) and positive likelihood ratio (LR+), using citrated-plasma from 429 patients (prospective cohort study of 4Ts scoring; HIT, n=31), and from consecutive HIT patients (n=125), using reference standard serotonin-release assay (SRA)...

Unlike clozapine, and despite its structural similarities, olanzapine is not usually associated with haematological suppression. Nonetheless this case report highlights an incident of olanzapine-induced thrombocytopenia and neutropenia in a first-contact patient. We report on a 50-year-old male who presented with 7 years of delusions and hallucinations. A diagnosis of schizophrenia was made in the absence of any suggestive features of mood disorders, substance abuse or organicity, and olanzapine as second-line treatment...

In this work, we evaluate the potential risk of thrombocytopenia in man for a BRD4 inhibitor, AZD5153, based on the platelet count decreases from a Han Wistar rat study. The effects in rat were modeled and used to make clinical predictions for human populations with healthy baseline blood counts. At doses >10 mg, a dose-dependent effect on circulating platelets is expected, with similar predicted changes for both QD and BID dose schedules. These results suggest that at predicted efficacious doses, AZD5153 is likely to have some reductions in the clinical platelet counts, but within the normal range at projected efficacious doses...

Heparin-induced thrombocytopenia (HIT) is a serious drug reaction that leads to a decrease in platelet count and a high risk of thrombosis. HIT patients produce pathogenic immunoglobulin G (IgG) antibodies that bind to complexes of platelet factor-4 (PF4) and heparin. HIT immune complexes crosslink Fc-receptors resulting in platelet and monocyte activation. These events lead to the release of procoagulant chemokines and tissue factor, which together create an intensely prothrombotic state. HIT represents an atypical immune response because it has features of both T cell-dependent and T cell-independent mechanisms...

Direct-acting oral anticoagulants (DOACs) were claimed to cause a potential paradigm shift in the therapeutic scenario of patients requiring short- and long-term anticoagulation, by virtue of their pharmacological properties, perceived as innovative. The evidence gathered so far (from pre-approval pivotal trials to real-world post-marketing observational data) consistently confirmed that DOACs are overall comparable to vitamin-K antagonists (VKAs) in terms of safety, efficacy and effectiveness and unequivocally documented a consistent and clinically relevant reduced risk of intracranial bleeding in the settings of non-valvular atrial fibrillation (NVAF) and venous thromboembolism (VTE)...

Oxaliplatin-based chemotherapy plays an important role in the treatment of colorectal liver metastases. Oxaliplatin, however, causes sinusoidal obstruction syndrome (SOS), which is characterized by portal hypertension, splenomegaly, thrombocytopenia, and liver dysfunction. SOS is diagnosed histopathologically by disruption of the sinusoidal endothelium, collagen deposition, fibrosis especially around zone 3, dilatation of the sinusoidal space and congestion. This study assessed the characteristics of a rat model of SOS...

Monitoring of direct thrombin inhibitors (DTIs) in patients with heparin-induced thrombocytopenia (HIT) is primarily performed using the activated partial thromboplastin time (aPTT). This assay is poorly standardized, reagent dependent, and not DTI specific. We compared aPTT, thrombin time (TT), and prothrombin time (PT) to drug levels obtained by the ecarin chromogenic assay (ECA). We analyzed 495 samples of patients with confirmed or suspected HIT on treatment with either argatroban (n = 37) or lepirudin (n = 80)...

Because of a lack of platelet supply and a U.S. Food and Drug Administration-approved platelet growth factor, megakaryocytes have emerged as an effective substitute for alleviating thrombocytopenia. Here, we report the development of an efficient two-stage culture system that is free of stroma, animal components, and genetic manipulations for the production of functional megakaryocytes from hematopoietic stem cells. Safety and functional studies were performed in murine and nonhuman primate models. One human cryopreserved cord blood CD34(+) cell could be induced ex vivo to produce up to 1...

Apixaban is a relatively new drug, and its safety profile is still being established. Thrombocytopenia is an uncommon, but life-threatening side effect with no previous published case repots. Clinicians must be aware of this and exercise caution particularly as some studies hint that it may be used in the management of HIT.
