Hypertension in chronic glomerulonephritis.

In 74 chronic glomerulonephritis (CGN) and 13 hemodialysis patients (HD) blood volume and hemodynamic indices were examined. Significant correlation was observed between MPA and PV in CGN. High PV in high S-Cr group is considered to be correlated with anemia. Salt restriction reduced MAP without the change in BV in the impaired kidney function group in CGN. Volume depletion in HD shifted TPRI to lower level in the group with significant MAP reduction. The results indicate that sodium rather than water will play an important role in this type of hypertension.
