Transthyretin-mediated amyloidosis (ATTR) is a progressive, multisystem, life-threatening disorder characterized by the extracellular deposition of misfolded, insoluble amyloid fibrils. The role of the TTR protein is to transport thyroxine and retinol-binding proteins, and it is vital for cognition, nerve regeneration, and axonal growth. TTR itself is innately amyloidogenic even without the presence of genetic mutations, which may account for wild-type ATTR (wtATTR), while a hereditary form of ATTR (hATTR) may be passed to offspring through autosomal dominant inheritance. Left untreated, the average life expectancy of ATTR is 3 to 15 years from symptom onset.

Target Audience:
The following HCPs: neurologists, cardiologists, and hematologists; physician assistants, nurse practitioners, and pharmacists in the aforementioned areas of specialty; and any other HCPs with an interest in or who may clinically encounter patients with ATTR.

Systemic mastocytosis (SM) is a heterogeneous group of disorders caused by proliferation of abnormal clonal mastocytes, which accumulate in the skin and/or other organ systems. Mastocytosis, including SM, was reclassified as a distinct disease subtype in 2016, when the World Health Organization (WHO) removed mastocytosis from the myeloproliferative neoplasm (MPN) group. The WHO defines 5 SM subtypes, ranging from indolent SM, which is associated with mild symptoms and near-normal life expectancy, to mast cell leukemia, which is an aggressive hematologic malignancy associated with median survival of less than 1 year.

Target Audience:
HCPs including: hematology/oncology specialists, allergists, and clinical immunologists, dermatologists; physician assistants, nurse practitioners, and pharmacists who practice in those areas of specialty; and any other healthcare professionals with an interest in or who may clinically encounter patients with systemic mastocytosis.

Thalassemias belong to a group of recessively inherited blood disorders characterized by little or no hemoglobin production and chronic anemia of varying severity. Alpha-thalassemia (AT) is most commonly found in people of Mediterranean, Middle Eastern, Asian, and North African descent. Worldwide, 5% of people are AT carriers, with a much higher prevalence in certain regions (eg, up to 23% in Southeast Asia). AT is typically caused by deletions of one or more α-globin genes, of which there are 4 in total, leading to reduced or abolished α-globin production; nondeletional forms of AT can also occur and are generally more severe. The loss of functional α-globin disrupts the globin chain equilibrium, leading to excess γ- and β-globin chain formation and causing ineffective erythropoiesis.

Target Audience:

The following healthcare professionals: hematologists; physician assistants, nurse practitioners, and pharmacists who practice in hematology; and any other healthcare professionals with an interest in or who may clinically encounter patients with AT.

Acute hepatic porphyria (AHP) is an umbrella term for four types of acute porphyria, the most severe of which is acute intermittent porphyria (AIP). An estimated 80% of AHP cases are AIP, which is an inherited autosomal dominant condition that results from mutations of the third enzyme of heme synthesis, porphobilinogen deaminase. In the Western countries, it is estimated that approximately 1 in 2000 individuals are carriers of the relevant mutated genotype, although the majority have latent AIP and are clinically asymptomatic. Acute attacks occur in less than 10% of the at-risk population, reflecting the role of environmental factors, such as alcohol use, infections, and hormonal changes, among others. AHP symptoms are believed to be caused by ALAS1-mediated accumulation of ALA and PBG in the liver and bloodstream, leading to neurotoxicity.

Target Audience:
The following HCPs: hematologists and gastroenterologists; physician assistants, nurse practitioners, and pharmacists who practice in any of the aforementioned areas of specialties; and any other healthcare professionals with an interest in or who clinically encounter patients with AHP.

Sickle cell disease (SCD) is the most common monogenic blood disorder, affecting millions of people worldwide and approximately 100,000 Americans. Although it may be found in various areas of the world, SCD predominantly affects individuals of African or Hispanic heritage. It is caused by the inheritance of b-globin alleles that code for hemoglobin S, resulting in an amino acid substitution in hemoglobin’s b chain and clinical disease. Patients with SCD have impaired circulation, and lysis of the erythrocytes contributes to a chronic inflammatory response, causing severe pain and less efficient oxygen delivery. The hallmark clinical features of SCD are hemolytic anemia and painful vaso-occlusive crises (VOCs), which may lead to emergency department visits, hospitalization, and potentially fatal complications such as acute chest syndrome, stroke, or pneumonia. In one US study, 45% of deaths among people with SCD were related to cardiopulmonary causes, and VOCs alone have been shown to increase the risk of death by 50%. SCD may disrupt employment or school and is associated with a significant reduction in quality of life. This learning activity has been designed to bring HCPs’ knowledge of rationale behind treatment of SCD up to date and to enhance their competence and performance in the condition’s management.

Graft-versus-host disease (GvHD) is an immune-mediated response that occurs in recipients of allogenic hematopoietic cell transplantation (HCT). GvHD can be further categorized into acute and chronic cases. Maculopapular rash, follicular erythema, epidermolysis, are common manifestations of acute GvHD, in addition to liver and gastrointestinal dysfunction such as hyperbilirubinemia, nausea, and diarrhea. This activity focuses on chronic GvHD, which has more extensive multi-organ involvement including the liver, eyes, mouth, lungs, skin, genitalia, and gastrointestinal tract.

Target Audience:

The following HCPs: hematologists and oncologists; nurse practitioners, physician assistants, and pharmacists who specialize in oncology; and those who otherwise commonly care for or clinically encounter patients with GVHD.

Thalassemias are a group of recessively inherited blood disorders characterized by little or no hemoglobin production and chronic anemia of varying severity. Beta-thalassemia (BT) is most commonly found in people of Mediterranean, Middle Eastern, Asian, and North African descent. Worldwide, 1.5% of people are BT carriers, with about 40,000 infants born with BT annually. About half of patients with BT are transfusion-dependent, which may significantly impact patient quality of life. BT is caused by a point mutation in the gene encoding hemoglobin subunit beta (HBB), resulting in either lower beta-globin production (termed beta-plus [B⁺]) or the prevention of all beta-globin production (termed beta-zero [B⁰]). Disease severity depends on the extent of hemoglobin β and γ chain imbalance.

Target Audience:

The following HCPs: hematologists; physician assistants, nurse practitioners, and pharmacists who practice in hematology; and any other healthcare professionals with an interest in or who may clinically encounter patients with beta-thalassemia.
