Haemoglobin Bristol-Alesha in a child with non-spherocytic severe haemolytic anaemia and marked anisochromic poikilocytosis with basophilic stippling and amorphous intracellular content.

Here we describe a retrospective study of a 10-year-old girl, adopted from India, and referred to the Rare Anemias Unit for the diagnosis of a severe haemolytic anaemia of unknown etiology. Blood film examination revealed markedly abnormal red cell morphology characterised by a mixture of very pale (hypochromic) cells with basophilic stippling and macrocytic cells containing coarse basophilic dots and an amorphous material of unknown origin. With a presumptive diagnosis of pyruvate kinase deficiency (PK), the patient had been splenectomised at 7 years of age with a partial recovery of the anaemia and a decrease of the blood transfusion rate.

Concise review: how do red blood cells born, live, and die?

The average life cycle of a human RBC is approximately 120 days. Generally, by this point, the cell is worn out and damaged. RBCs pass through both the spleen and liver, where specialised immune cells called macrophages are found.

A comprehensive update of ICET-A Network on COVID-19 in thalassemias: what we know and where we stand.

A review of the literature on COVID-19 pandemic in patients with thalassemias is presented. Globally, the prevalence of COVID-19 among  β-thalassemia patients seems to be lower than in general population; associated co-morbidities aggravated the severity of  COVID- 19, leading to a poorer prognosis, irrespective of age. A multicenter registry will enhance the understanding of COVID-19 in these patients and will lead to more evidence-based management recommendations.

Preliminary Data on COVID-19 in Patients with Hemoglobinopathies: A Multicentre ICET-A Study.

Objectives: This study aims to investigate, retrospectively, the epidemiological and clinical characteristics, laboratory results, radiologic findings, and outcomes of COVID-19 in patients with transfusion-dependent β thalassemia major (TM), β-thalassemia intermedia (TI) and sickle cell disease (SCD).

Design: A total of 17 Centers, from 10 countries, following 9,499 patients with hemoglobinopathies, participated in the survey.

Main Outcome Data: Clinical, laboratory, and radiologic findings and outcomes of patients with COVID-19 were collected from medical records and summarized.
