The effect of plasma exchange (PE) on blood pressure (BP) in 20 hypertensive patients (9 with mixed cryoglobulinemia, 7 with systemic lupus erythematosus, and 4 with idiopathic glomerulonephritis) was evaluated retrospectively. In each PE 1.5-2.5 L of plasma was replaced with an equal volume of 4% albumin polysaline solution. The frequency of PE was three times per week for the first 2 weeks and twice per week subsequently. Sixteen patients were on hypotensive treatment at the onset of PE. Their systolic/diastolic BP was 171 +/- 4.7/102 +/- 3.0 mm Hg (mean +/- 1 SEM). After 4 weeks, BP decreased to 141 +/- 2.8/89 +/- 2.3 mm Hg (p less than 0.001), although in 10 patients antihypertensive drug therapy had been reduced or discontinued. The most marked decrease of BP occurred after the first week (152 +/- 5.3/92 +/- 2.9 mm Hg), and this decrement correlated remarkably well with pressure levels before PE despite the great heterogeneity of the individual patients (for diastolic BP, r = 0.87, p less than 0.001; for systolic BP, r = 0.60, p less than 0.01). A mild decrease of serum creatinine was observed during PE, but its time course was different from that of BP, and did not correlate with this parameter.

Abstract

The effect of plasma exchange (PE) on blood pressure (BP) in 20 hypertensive patients (9 with mixed cryoglobulinemia, 7 with systemic lupus erythematosus, and 4 with idiopathic glomerulonephritis) was evaluated retrospectively. In each PE 1.5-2.5 L of plasma was replaced with an equal volume of 4% albumin polysaline solution. The frequency of PE was three times per week for the first 2 weeks and twice per week subsequently. Sixteen patients were on hypotensive treatment at the onset of PE. Their systolic/diastolic BP was 171 +/- 4.7/102 +/- 3.0 mm Hg (mean +/- 1 SEM). After 4 weeks, BP decreased to 141 +/- 2.8/89 +/- 2.3 mm Hg (p less than 0.001), although in 10 patients antihypertensive drug therapy had been reduced or discontinued. The most marked decrease of BP occurred after the first week (152 +/- 5.3/92 +/- 2.9 mm Hg), and this decrement correlated remarkably well with pressure levels before PE despite the great heterogeneity of the individual patients (for diastolic BP, r = 0.87, p less than 0.001; for systolic BP, r = 0.60, p less than 0.01). A mild decrease of serum creatinine was observed during PE, but its time course was different from that of BP, and did not correlate with this parameter.
