Imatinib mesylate-induced acute hepatotoxicity.

Introduction: Imatinib is a first-line selective tyrosine kinase inhibitor used for the treatment of chronic myeloid leukemia. Although imatinib-induced hepatotoxicity may aggravate the patient's clinical condition and alter the treatment plan, the mechanism of imatinib-induced hepatotoxicity has rarely been investigated.

Case Report: We report a 51-year-old man, suffering from acute toxic hepatitis after 5 months of imatinib treatment for chronic myeloid leukemia.

Prospective observational study of palliative care in hematological malignancies: Report of one year of practice.

Introduction: Palliative care is an approach that improves the quality of life of patients with advanced disease.

Objective: The aim of this study is to evaluate the process of palliative care in patients with hematologic malignancies.

Methods: In this prospective observational study, we included patients with hematologic malignancies who received palliative care over a 12 month period from June 1, 2019, to May 31, 2020 at the day care hospital of the hematology department in University Hospital of Sfax, Tunisia.

Overexpression of P-glycoprotein and resistance to Imatinib in chronic myeloid leukemia patients.

Background: The P-glycoprotein (P-gp) is one of the mechanisms of Imatinib (IM) resistance in chronic myeloid leukemia (CML). P-gp has been identified as an efflux pump involved in releasing of IM outside CML cells. To date, the P-gp involvement in the IM resistance development was not completely understood.

Original tandem duplication in FXIIIA gene with splicing site modification and four amino acids insertion causes factor XIII deficiency.

: Recessive mutations of F13A gene are reported to be responsible of FXIIIA subunit deficiency (FXIIIA). In all, some intronic nucleotide changes identified in this gene were investigated by in-silico analysis and occasionally supported by experimental data or reported in some cases as a polymorphism. To determine the molecular defects responsible of congenital factor XIII deficiency in Libyan patient, molecular analysis was performed by direct DNA sequencing of the coding regions and splice junctions of the FXIIIA subunit gene (F13A).

[Primary immune thrombocytopenia in childhood: a regional study in the south of Tunisia].

Background: the primary immune thrombocytopenia (ITP) in children has a favorable evolution in most of cases. aim: describe the epidemiological and therapeutic data and the outcome of primary immune thrombocytopenia in our patients and propose a treatment plan to standardize the management of this disease in our region. methods: We conducted a retrospective study of 140 cases of primary immune thrombocytopenia collected in department of pediatrics and hematology of Hedi Chaker hospital during a period of 15 years.

Comprehensive analysis of BCR/ABL variants in chronic myeloid leukemia patients using multiplex RT-PCR.

Background: A specific chromosomal abnormality, the Philadelphia chromosome (Ph), is present in 90 - 95% of patients with chronic myeloid leukemia (CML). This aberration results from a reciprocal translocation between chromosomes 9 and 22, creating a BCR/ABL fusion gene. The diagnosis of CML is based on the detection of BCR/ABL gene or Ph chromosome.

[Extra medullary hematopoiesis associated to congenital dyserythropoietic anemia II in adult].

The congenital dyserythropoietic anemias comprise a group of rare hereditary disorders of erythropoiesis characterized by anemia with ineffective erythropoiesis and morphological abnormalities of erythroblasts in the bone marrow. Congenital dyserythropoietic anemia type II or HEMPAS is the more frequent type. It is rare in adults.

Congenital factor XIII deficiency caused by two mutations in eight Tunisian families: molecular confirmation of a founder effect.

Inherited factor XIII (FXIII) deficiency is a rare bleeding disorder characterized by an umbilical bleeding during the neonatal period, delayed soft tissue bruising, mucosal bleeding spontaneous intracranial hemorrhage, and soft tissue hemorrhages. Congenital FXIII deficiency is an autosomal recessive disorder, usually attributed to a defect in the FXIIIA and B subunits coding, respectively, by F13A and F13B genes. The aim of this study was to determine the molecular defects responsible for congenital factor XIII deficiency in eight Tunisian families.
