Q

What is CAR-T therapy

A

Genetically modified autologous immunotherapy targeting CD-19 where a person’s own T-cells are genetically modified to direct the patient’s T cells against the leukemic cells. However, cytokine release storm occurs in 70-90% of patients. (Used as second or thrid line therapy because of this reason)

A

INdolent

35
Q 
Are these aggressive or indolent? 
• Diffuse Large B cell Lymphoma (DLBCL)
• Burkitt Lymphoma
• Mantle Cell Lymphoma
• Peripheral T cell Lymphomas
A

Aggressive

36
Q

This is an aggressive type of lymphoma that is the mc lymphoma worldwide. It typically presents with a rapidly enlarging symptomatic mass in the neck or abdomen. Can be associated with EBV.

A

Diffuse Large B Cell Lymphoma

37
Q

This type of lymphoma has painless peripheral adenopathy and can see it in a lot of nodes but it commonly waxes and wanes but never really goes away.

A

Follicular lymphoma

38
Q

This is a highly aggressive B cell neoplasm that comprises of 30% of pediatric lymphomas in the US. Typically endemic in Africa and can be associated with HIV

A

Burkitt Lymphoma

39
Q

Patients with burkitt can have a high propensity for tumor lysis syndrome (like cytokine storm) and you might commonly see what lab result because of it?

A

Hyperuricemia (put lots of people on allopurinol because of it)

40
Q

This lymphoma can involve any region of the GI tract and nuclear staining for D1 is present in 95% of cases

A

Mantle cell lymphoma

41
Q

What is a marginal zone?

A

Type of slow growing non-Hodgkin lymphoma that develop from B cells

42
Q

Extranodal marginal zone lymphoma of mucosa associated lymphoid tissue (MALT lymphoma)

A

Marginal zone lymphoma

43
Q

This type of lymphoma is frequently due to chronic gastritis from H.pylori infections and arrises from tissue in the stomach. Also common in Hispanics

A

Marginal zone lymphoma

44
Q

This lymphoma is associated with IgM monoclonal gammopathy and smudge cells can be pressent

A

Lymphoplasmacytic Lymphoma

45
Q

Neoplastic proliferation of plasma cells producing an monoclonal immunoglobulin and proliferation of plasma cells causes skeletal destruction with osteolytic lesions, osteopenia, and/or pathologic fracture

A

Multiple myeloma

46
Q

CRABS

A

Calcemia, renal dysfunction, Anemia, bone lesions

49
Q

Lytic lesions (punched out) on skeletal imaging

A

multiple myeloma

50
Q

These two things are needed to make the diagnosis of multiple myeloma

A
  1. Clonal bone marrow plasma cells greater than or equal to 10% or bx proven bony or soft tissue plasmacytoma
  2. PLUS presence of related organ impairment or tissue impairment (CRABS)
51
Q

Tx for multiple myeloma?

A

Non-curable but a stem cell transplant can prolong life (an attempt to buy time)

52
Q

Heterogrnous group of malignant hematopoietic stem cell disorders characterized by dysplastic and ineffective blood cell production

A

Myelodysplastic syndrome

53
Q

What is primary hemostasis?

A
  • Primary hemostasis refers to the initial steps in clot formation, which mostly rely on vessel wall and platelet function
  • Disorders of primary hemostasis often present with mucocutaneous bleeding or petechiae
54
Q

What is secondary hemostasis?

A
  • Secondary hemostasis refers to the subsequent formation of the fibrin- based clot, which mostly relies on coagulation factors
  • Disorders of secondary hemostasis present with deep tissue hematomas or joint bleeding
55
Q

Hemostasis can occur due to what three things?

A
  1. Platelet dysfunction
  2. Increased platelet destruction
  3. Decreased platelet production
56
Q

This is when there is an antibody destruction of platelet and can also be known as ITP

A

Immune Thrombocytopenic Purpura

57
Q

What are some sx/sxs of ITP

A

petechia, purpura, bleeding

58
Q
  • Antibody mediated destruction of platelets
  • Acquired with use of heparin
  • Antibody platelet factor 4 and heparin which triggers thrombosis
A

Heparin Induced Thrombocytopenia

59
Q

• Deficiency of the ADAMTS13 protease, which results in accumulation of very long von Willebrand factor multimers on the endothelial surface that are capable of binding platelets

A

TTP (Thrombocytic Thrombocytopenic Purpura)

60
Q

What is the pentad of symptoms of TTP?

A

Fever, thrombocytopenia, renal failure, neuro changes, microangiopathic anemia (hemolytic)

61
Q

• Abnormalities in the vessel wall of arterioles and capillaries lead to microvascular thrombosis

A

TTP

62
Q

• Abnormalities in the vessel wall of arterioles and
capillaries lead to microvascular thrombosis – similar to TTP
• Complement-induced damage to the endothelium from shiga toxin

A

Hemolytic Uremic Syndrome

63
Q
  • Shiga toxins are produced by Shigella dysenteriae and some serotypes of Escherichia coli
  • Renal dysfunction more common than with TTP
A

HUS

64
Q
  • Dysfunction of platelets and coagulation cascade

* Activation of clotting and fibrinolytic system (bleeding and clotting at the same time)

A

DIC

65
Q

What are the tree causes of disorders of secondary hemostasis?

A

VWF, Hemophilia A, Hemophilia B, hypercoag states

Q
  • Deficiency of Von Willebrand factor (carrier for factor VIII)
  • Most common inherited bleeding disorder
  • Most cases are autosomal dominant
A
