Q1 · Hypersensitivity Reactions
NEET PGMediumExplanation
Anaphylaxis is a Type I, IgE-mediated hypersensitivity with mast-cell degranulation. Type II is antibody-mediated cytotoxicity, Type III is immune-complex-mediated and Type IV is T-cell-mediated delayed hypersensitivity.
Q2 · Amyloidosis
NEET PGMediumExplanation
Amyloid stains with Congo red and shows apple-green birefringence under polarised light because of its beta-pleated sheet structure. Types include AL from light chains and AA from serum amyloid A in chronic inflammation.
Q3 · Systemic Lupus Erythematosus
HardExplanation
Anti-double-stranded DNA and anti-Smith antibodies are highly specific for SLE. ANA is sensitive but not specific. Anti-dsDNA titres also correlate with disease activity, especially in lupus nephritis.
Q4 · Delayed Hypersensitivity
MediumExplanation
The Mantoux reaction is a Type IV delayed hypersensitivity mediated by sensitised T cells and macrophages, peaking at 48 to 72 hours. Contact dermatitis and granuloma formation share this mechanism.
Q5 · Immunodeficiency
EasyExplanation
HIV infects and depletes CD4 T helper cells. A CD4 count below 200 cells per microlitre defines AIDS and predisposes to opportunistic infections such as Pneumocystis pneumonia and cryptococcal meningitis.
Immunopathology sits within Pathology, which carries the same syllabus in both exams. This set runs to 5 questions, each tagged Easy, Medium or Hard, 1 of them at Hard, and 2 drawn from previous-year papers.
Answer first, then read the explanation even on the ones you got right — the reasoning is where Immunopathology marks are actually won, and it is what separates a recalled fact from a question you can solve in a new form. Once the Easy set feels comfortable, filter to Hard to find the gaps Pathology examiners keep returning to.
