Transcranial Doppler ultrasonography in patients with hemoglobinopathy: An experience from a tertiary center.

Objective: Patients with hemoglobinopathy are prone to cerebrovascular event. Our aim was to screen the peak systolic flow velocity (PSV) using transcranial Doppler ultrasonography (TCD) in terms of cerebrovascular event risk in patients with beta thalassemia (β-thal) and sickle cell anemia (SCA).

Methods: PSV and resistive index (RI) values were determined at internal carotid artery (ICA) and middle cerebral artery (MCA)-from both temporal regions using TCD.

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.
