Various Immunological diseases

Question 1

Membranous glomerulonephritis

Answer 1

antibody mediated disease in which immune complexes localize to the subepithelial aspect of capillary loop (between basement membrane and podocyte)
granular subepithelial deposits of IgG and C3

Question 2

Membranoproliferative glomerulonephritis

Answer 2

chronic progressive glomerulonephritis that occurs in older children and adults
circulating immune complexes identified and activation of complement system with hypocomplementemia

Question 3

Allergic pneumonitis

Answer 3

inflammation in the lungs caused by exposure to an allergen

Question 4

Pernicious anemia

Answer 4

insufficient intrinsic factor

Question 5

Allergic gastroenteropathy

Answer 5

gastrointestinal food allergies

Question 6

Sarcoidosis

Answer 6

disease due to inflammation
presence of granulomas, inside the body or exterior
frequently found in the lungs, granulomas appear in walls of alveoli or walls of bronchioles

Question 7

Polyarteritis nodosa

Answer 7

systemic necrotizing vasculitis of small and medium-sized arteries in multiple systems
immune complexes deposition on vessel walls

Question 8

Acute disseminated encephalomyelitis

Answer 8

inflammation of the brain and spinal cord caused by damage to the myelin sheath
autoimmune

Question 9

Arthus reaction

Answer 9

type III hypersensitivity

local inflammatory response due to deposition of immune complexes in tissues following injection of soluble antigens

Question 10

Drug-induced hemolytic anemia

Answer 10

occurs when certain drugs interact with the RBC membrane causing cell to become antigenic

Question 11

Progressive systemic sclerosis

Answer 11

autoimmune disease characterized by diffuse thickening of the skin and internal organs

Question 12

Serum sickness

Answer 12

Type III hypersensitivity reaction

results from the injection of heterologous or foreign protein or serum
