Clot waveform analysis in hemophilia carriers.

In recent years, there has been a growing interest in the activated partial thromboplastin time clot waveform analysis (APTT-CWA), which reflects clot formation. It was mainly studied in hemophilia and disseminated intravascular coagulation. The aim of this study was to evaluate the usefulness of APTT-CWA in hemophilia carriers.

Flow cytometry for meningeal infiltration in B acute lymphoblastic leukemia in a low middle income country.

Meningeal infiltration in children with B acute lymphoblastic leukemia is one of the most serious complications. Timely diagnosis not only significantly enhances treatment efficacy but also leads to improve patient outcome and reduce risk of relapse. This is particularly crucial in low to middle income countries facing health constraints, where optimizing resources is essential.

Clot waveform analysis in acute promyelocytic leukemia.

The aim of this study was to evaluate the activated partial thromboplastin time (APTT) and prothrombin time (PT)-based clot waveform analysis (CWA) in patients diagnosed with acute promyelocytic leukemia (APL). APTT-based and PT-based CWA parameters of patients diagnosed with APL were analyzed and compared with healthy volunteers. Four APTT-CWA parameters were noted, maximum velocity corresponding to the first peak of the first derivative (max1), maximum acceleration corresponding to the first peak of the second derivative (max2) and the corresponding peak times of max1 and max2 (Tmax1, Tmax2).

Factor XI deficiency: About 20 cases and literature review.

Introduction: Factor XI deficiency is a rare coagulation disorder with variable bleeding manifestations.

Aim: To evaluate the correlation between the degree of factorXI deficiency and the clinical expression of the disease.

Methods: Retrospective study, spanning 10 years from January 1, 2010 to December 31, 2019, concerning patients followed at the Hemophilia Center at Aziza Othmana Hospital in Tunis.

Acquired FVII Deficiency and Acute Myeloid Leukemia: A Case Report and Literature Review.

Factor VII (FVII) deficiency is the most common among all rare inherited bleeding disorders. However, acquired FVII deficiency (aFVIID) is uncommon. Only few cases in the literature have been reported.

[Contribution and limits of CD157 in the detection of the paroxysmal nocturnal hemoglobinuria clone: a case report].

Flow cytometry is the gold standard for the detection of paroxysmal nocturnal hemoglobinuria (PNH) clones. Several antibody panels have been used with varying sensitivities and specificities. The CD157 is one of the glycosylphosphatidylinositol-anchored molecules tested and widely used.

Haemodialysis Tunisian patient with acquired factor V inhibitor associated to arteriovenous shunt thrombosis.

Factor V deficiency is a rare hemostatic disorder. It may present with a diverse spectrum of symptoms due to a variety of mechanisms including development of autoantibodies associated with a number of conditions. We report a first case of factor V deficiency in Tunisian hemodialysis patient due to an autoantibody most likely secondary to antibiotic exposure responsible for an arteriovenous shunt thrombosis rather than bleeding.
