Exercise 13

A 32-year-old construction worker experiences respiratory difficulty followed by the appearance of blood-streaked sputum. He delays visiting a physician until symptoms of extreme fatigue and red urine are present. A chest radiograph shows pulmonary infiltration, and sputum culture is negative for pathogens. Blood test results indicate anemia, increased BUN and creatinine, and the presence of antiglomerular basement membrane antibody. Urinalysis results are as follows:

a. What disorder do the laboratory results suggest?

b. How is this disorder affecting the glomerulus?

c. If the antiglomerular membrane antibody test is negative, what disorder might be considered?

d. What is the diagnostic test for this disorder?

e. By what mechanism does this disorder affect the glomerulus?
