Archives for Virtual Grand Rounds and Webinars on Thalassemia
Following are virtual grand rounds and webinars on a variety of topics that focus on a collection of inherited blood disorders called the thalassemias. These offerings have been developed through funding by the Centers for Disease Control and Prevention.

The non-transfusion-dependent thalassemias are a diverse group of disorders caused by mutations in the alpha or beta-globin genes that affect hemoglobin synthesis and lead to an anemia ranging from mild to severe. The unifying principle is that such individuals are clinically determined to not require regular red cell transfusions in contrast with transfusion-dependent thalassemia. While many are asymptomatic and never transfused, others need intermittent transfusions during periods of infection, pregnancy, or surgery.
In these rounds, Dr. Ashutosh Lal discusses the challenges faced by hematologists in managing individuals with non-transfusion-dependent thalassemia. He also examines how the diagnosis can sometimes be difficult due to complex underlying genetic mutations.

A. Watson and Sarah Armour Endowed Chair for Blood Diseases and Cancer

The thalassemia syndromes are a group of genetic blood disorders in which the production of one of the two different globin proteins (alpha or beta) that make up hemoglobin is reduced or absent. The result is anemia due to both ineffective erythropoiesis and chronic hemolysis, which typically begins in early childhood and lasts throughout life.
The clinical severity of thalassemia and interventions needed depend upon the globin chain affected and the type of genetic mutation. Persons with the most severe forms of thalassemia often require regular transfusions to treat the anemia and chelation therapy to prevent iron overload and associated sequelae. However, many patients with transfusion-dependent thalassemia (TDT) have struggled with adherence to the ongoing, intensive treatment regimen. Recent innovations, such as oral iron chelation agents, have helped improve adherence, and thus, prognoses (i.e., survival and quality of life in persons with TDT). Nonetheless, some patients and families are interested in definitive, potentially curative treatments.
In this webinar, Dr. Thompson describes considerations for stem cell transplantation, including patient characteristics, donor stem cell sources, and preparative regimens that impact clinical outcomes. She provides an overview of genomic therapies, such as gene addition and gene editing, and reviews the results of clinical studies on thalassemia.
Farzana Sayani, MD, MSc
Assistant Professor of Medicine Hospital of the University of Pennsylvania, Philadelphia, Pennsylvania
Director, Penn Comprehensive Adult Thalassemia Program
As thalassemia care is improving, more individuals with thalassemia are reaching adulthood with aspirations to start a family of their own. However, infertility is one of the major complications of iron overload in patients with thalassemia.
In this webinar, Dr. Sayani reviews the causes of infertility in individuals with thalassemia. She also discusses methods to preserve and evaluate fertility, management options for infertility, and other options available to start a family.
Mona Al Mukaddam, MD, MS
Director, Penn Bone Center
Assistant Professor of Clinical Medicine and Orthopaedic Surgery; Perelman School of Medicine
University of Pennsylvania
Rahul Agarwal, MD
Assistant Professor of Medicine, Endocrinology, Diabetes & Bone Disease; Icahn School of Medicine, Mount Sinai Health
In these rounds, Mona Al Mukaddam, MD, MS, reviews the factors that contribute to bone disease in transfusion-dependent thalassemia. She also reviews the screening guidelines for low bone mass and discuss treatment options for osteoporosis in thalassemia. Rahul Agarwal, MD, presents a case study highlighting the effective management of osteoporosis in thalassemia.

Chief of Pediatric Hematology and Oncology
Vice Chair for Clinical Research, Department of Pediatrics, Weill Cornell Medicine
Director, New York Comprehensive Thalassemia Center, New York-Presbyterian Hospital/Weill Cornell Medical Center
Ashutosh Lal, MD
Professor of Pediatrics
UCSF School of Medicine
Director, Comprehensive Thalassemia Program
Co-Director, Bio-Iron Program

Elliott Vichinsky, MD
Professor of Pediatrics
UCSF School of Medicine
Director, Northern California Comprehensive Thalassemia Program
Medical Director, Hematology/Oncology
UCSF Benioff Children’s Hospital Oakland
The introduction of effective red blood cell (RBC) transfusions 50 years ago was a critical step in transforming thalassemia from a severe, fatal anemia into a chronic condition. In this webinar, Dr. Vichinsky and Dr. Lal review the range of complications associated with RBC transfusions in thalassemia. They also describe the guidelines for transfusion therapy in beta thalassemia major, the most common form of transfusion-dependent thalassemia. The webinar will also address transfusions in alpha thalassemia major, and recommendations for non-transfusion-dependent thalassemia.
Thalassemia Management: Balancing Blood and Ironexternal icon
Janet L. Kwiatkowski, MD, MSCE
Director, Thalassemia Center of Children’s Hospital of Philadelphia
Professor of Pediatrics, Perelman School of Medicine, University of Pennsylvania
In this webinar, Dr. Kwiatkowski provides an overview of current, recommended treatments for people with thalassemia, with an emphasis on transfusion-dependent thalassemia. She discusses best practices in transfusion, as well as monitoring and treatment of iron overload.

Lauren Mednick, PhD
Assistant Professor of Psychology
