Acute poststreptococcal glomerulonephritis is primarily caused by:
a. swelling of mesangial cells in the Bowman space in response to the presence of bacte-ria.
b. immune complex deposition in the glo-merular capillaries and inflammatory damage.
c. inflammatory factors that stimulate cellu-lar proliferation of epithelial cells.
d. accumulation of antiglomerular basement membrane antibodies.
ANS: B
Acute poststreptococcal glomerulonephritis is caused by an antigen-antibody complex. Acute poststreptococcal glomerulonephritis is not due to swelling of the Bowman space. It is not an in-flammatory process nor is it caused by an accumulation of antiglomerular basement membrane antibodies.
