Acute lymphocytic leukemia in a patient with long-term carbamazepine exposure: Acute lymphoblastic leukemia that develops in a patient who has been using carbamazepine for a long time.

INTRODUCTION: Carbamazepine is an antiepileptic drug used in the treatment of epilepsy, trigeminal neuralgia, and bipolar disorder. Hematological effects that may develop with this anticonvulsant; agranulocytosis, thrombocytopenia, leukopenia, aplastic anemia, eosinophilia, or pancytopenia. CASE REPORT: In this article, we wanted to present a case diagnosed with acute lymphoblastic leukemia after long-term use of carbamazepine because of epilepsy. MANAGEMENT AND OUTCOME: Bone marrow smear was evaluated and blastic cell infiltration was observed. The carbamazepine treatment was discontinued and standard chemotherapy was started for acute lymphoblastic leukemia (CALGB protocol). Levetiracetam was started for epilepsy. DISCUSSION: Carbamazepine is an iminostilbene derivative. Carbamazepine is an antiepileptic drug that exhibits a number of side effects such as headache, abdominal pain, high blood pressure, as well as hematological disorders. In addition to causing thrombocytopenia, hypogammaglobulinemia, leukopenia, and neutropenia, it can have serious effects such as agranulocytosis, aplastic anemia, pure red cell aplasia, leukemia, or DRESS syndrome. The incidence of serious side effects from carbamazepine pharmacotherapy is low, and their exact mechanism of action is still unknown.

A multicenter retrospective analysis on therapeutic plasma exchange in immune thrombocytopenic purpura.

Immune Thrombocytopenia (ITP) is an autoimmune disease characterized by thrombocytopenia and skin and mucosal bleeding. In patients with an indication for treatment, corticosteroids, intravenous immunoglobulin (IVIg) and anti-D are recommended as the first line, while splenectomy, thrombopoietin receptor agonists or rituximab are recommended second line options. Approximately 10 % of adult patients with ITP fall into the chronic refractory ITP group. Therapeutic plasma exchange (TPE) has generally been tested in patients with refractory ITP, who have failed to respond to conventional treatments, in case of bleeding or prior to surgical interventions. It has been stated that elimination of the antibodies that are held responsible in the pathogenesis of the disease has an effective role in the treatment. In this article, we present the results of 17 patients, who underwent TPE for refractory ITP, together with the literature data.

KDIGO (Kidney Disease: Improving Global Outcomes) criteria as a predictor of hospital mortality in cirrhotic patients.

BACKGROUND/AIMS: Acute kidney injury (AKI) is frequent in cirrhotic patients and is associated with a poor prognosis. Recently, the Kidney Disease: Improving Global Outcomes (KDIGO) organization recommended new criteria for the diagnosis and staging for AKI. The aim of this study was to evaluate the presence of AKI according to KDIGO criteria in cirrhotic patients admitted to the hospital and to determine its association with hospital mortality. MATERIALS AND METHODS: This retrospective study included 277 cirrhotic patients admitted to the intensive care unit and gastroenterology service of a tertiary referral hospital from January 2008 to January 2012. AKI was diagnosed and classified according to the KDIGO criteria. RESULTS: The overall incidence of AKI in cirrhotic patients was 39%, and the overall hospital mortality was 15.5%. Patients without AKI had a hospital mortality rate of 2.4%, whereas the mortality rate for patients with AKI was 36.1%. The peak AKI stage detected during hospitalization was stage 1 for 58 patients (53.7%), stage 2 for 20 patients (18.5%), and stage 3 for 30 patients (27.7%). Mortality was found to be associated with the presence, stage, and progression of AKI. Multivariate analysis showed that AKI was an independent factor significantly associated with mortality (odds ratio: 9.1; 95% confidence interval: 2.89-29.1; p<0.001). CONCLUSION: KDIGO criteria can be used to evaluate AKI in cirrhotic patients. The prevalence of AKI in patients with cirrhosis is high, and AKI is associated with mortality. If early preventive measures are taken, it may be possible to prevent AKI progression and thus mortality.
