STUDY OF CLINICAL MANIFESTATIONS AND ETIOLOGIES OF MEGALOBLASTIC ANEMIA IN CHILDREN.
Transfus Clin Biol
January 2025
Background And Aim: Megaloblastic anemia (MA) is a rare pathology in childhood due, in the majority of cases, to a deficiency of folic acid and/or vitamin B12 (cobalamin). This study aims to determine the epidemiological, clinical, and paraclinical profiles of MA in children and to specify its etiologies, therapeutic modalities, and treatment responses.
Methods: This is a retrospective descriptive study of MA cases in children carried out in the General Pediatrics Department of the Hedi Chaker University Hospital of Sfax over a period of 42 years, from January 1979 to December 2021.

Vitamin B12 deficiency is a potentially severe condition with clinical manifestations ranging from nonspecific symptoms, such as asthenia and glossitis, to severe hematological problems, including pancytopenia and megaloblastic anemia. One of the rare phenomena associated with this condition is pseudo-thrombotic microangiopathy (pseudo-TMA), which can mimic diseases such as thrombotic thrombocytopenic purpura (TTP), leading to possible misdiagnosis and inappropriate treatment. In this article, we present the case of a 62-year-old man with a history of intravenous drug use, untreated hepatitis C, smoking, and alcoholism.

Hemophagocytic lymphohistiocytosis (HLH) is a rare and potentially fatal hyperinflammatory syndrome characterized by dysregulated immune activation and systemic inflammation. Secondary HLH is often triggered by infections, with being an infrequently reported cause. Peripheral axonal neuropathy is a rare and poorly understood complication of HLH.

Background: Hemophagocytic lymphohistiocytosis (HLH) is a non-neoplastic proliferation and macrophage activation that induces cytokine-mediated bone marrow suppression and features of intense phagocytosis in the bone marrow and liver, leading to multi-organ dysfunction and ultimate failure. The diagnosis of HLH in an intensive care setting is challenging, and it is associated with high morbidity and mortality. HLH-94 is the standard protocol for treatment, consisting of dexamethasone and chemotherapy like etoposide.
