Erythrocytes from patients suffering from acute lymphoid leukaemia (ALL) show decreased proportions of spectrin tetrameters and altered spatial distribution of band 4.1 and ankyrins. These abnormalities of the cytoskeleton are probably responsible for altered membrane fluidity and transbilayer distribution of phosphatidylethanolamine in ALL. ALL is associated with severe anaemia and usually, but not always, with overproduction of lymphocytes. To our knowledge, this is the first report of abnormalities in the erythrocyte membrane in ALL which may, in part, be responsible for the observed anaemia.

Hemoglobin A is a widely used diagnostic tool for monitoring glycemic control in diabetes management. However, its accuracy can be influenced by various factors. We present a case of a 17-year-old boy with abnormally low Hemoglobin A levels caused by warm autoantibody-induced hemolytic anemia.

Background Systemic Lupus Erythematosus (SLE) is a multifaceted autoimmune disorder with diverse clinical presentations, among which hematological abnormalities often serve as early and critical indicators of disease. These manifestations, including anemia, leukopenia, lymphopenia, and thrombocytopenia, correlate with disease activity and provide essential diagnostic insights, particularly in resource-limited settings where access to advanced diagnostic tools may be constrained. This study emphasizes the significance of hematological findings that frequently appear at the initial presentation of SLE.

Sickle cell disease (SCD) is an inherited hematologic disease caused by sickle hemoglobin as the predominant RBC hemoglobin or by sickle hemoglobin in combination with other abnormal β-hemoglobin variants like HbC, HbD and others. Sickling of erythrocytes under deoxygenated conditions is the basis of inflammatory and thrombotic cascades which result in multiple serious complications, leading to early morbidity and mortality. While HLA-matched allogeneic bone marrow transplantation is potentially curative, it has considerable limitations due to potential severe toxicities.

The present study investigated the individual and mixture effects of Arsenic (As) and Chromium (Cr) at their environmental concentrations in zebrafish (Danio rerio). After 15, 30 and 60 days of exposure, increased frequencies of erythrocytic nuclear abnormalities (ENAs) were noticed. After 60 days of exposure, DNA damage was observed in liver and base excision DNA repair (BER) and mismatch DNA repair (MMR) pathways were studied to know the cellular responses.

Severe valproic acid (VPA) overdose is characterized by coma (sometimes with cerebral oedema), respiratory depression, hypotension and metabolic abnormalities. Traditional management of VPA poisoning has been limited to gastrointestinal decontamination, L-carnitine supplementation and, in severe cases, haemodialysis. Recently, interest has developed in the use of carbapenem antibiotics as an adjunctive therapy in patients with severe VPA poisoning.
