Verified step by step guidance1
Step 1: Understand the types of hypersensitivity reactions. There are four main types (I-IV), with type III involving immune complex-mediated reactions where antigen-antibody complexes deposit in tissues causing inflammation and damage.
Step 2: Recognize that systemic type III hypersensitivity affects multiple organs due to widespread immune complex deposition, unlike localized reactions which affect a single site.
Step 3: Identify diseases associated with systemic type III hypersensitivity. Systemic lupus erythematosus (SLE) is a classic example where immune complexes form against nuclear components such as DNA, leading to multi-organ damage.
Step 4: Differentiate SLE from other options: Rheumatoid arthritis is primarily a type IV hypersensitivity; glomerulonephritis can be a manifestation of type III but is not systemic by itself; Arthus reaction is a localized type III hypersensitivity.
Step 5: Conclude that systemic lupus erythematosus (SLE) is the systemic type III hypersensitivity involving immune complexes against DNA that damage multiple organs.
