Step 1: Secondary (AA) amyloidosis develops as a complication of chronic inflammatory, infective or suppurative conditions that keep serum amyloid A protein persistently elevated.
Step 2: Classic associations include chronic infections such as tuberculosis, leprosy and chronic osteomyelitis, suppurative lung disease like bronchiectasis, and chronic inflammatory disorders such as rheumatoid arthritis (most common), ankylosing spondylitis and inflammatory bowel disease.
Step 3: Tuberculosis, chronic osteomyelitis and bronchiectasis are all recognised causes, so options a, c and d are linked to amyloidosis.
Step 4: Chronic bronchitis is not a classic suppurative or granulomatous condition associated with secondary amyloidosis. Hence chronic bronchitis is the exception and the correct answer.
