Following a respiratory infection, a 20-year-old man goes to his physician for a follow-up visit. Physical
examination is unremarkable, but dipstick analysis of his urine reveals marked proteinuria and microscopic
hematuria. The young man is referred to a specialist, who performs a renal biopsy. Immunofluorescence
microscopy of the biopsy tissue demonstrates IgA deposition in the glomerular mesangium. These results are
most consistent with which of the following disorders?
A. Berger's disease
B. Goodpasture's syndrome
C. Minimal change disease
D. Poststreptococcal glomerulonephritis
E. Systemic lupus erythematosus
