This study was based on the hypothesis that the development of metabolic alkalosis during TPE is more common in TTP than in MG, based on our previous observations. In order to test it, we compared the levels of bicarbonate and potassium in both groups of patients undergoing plasmapheresis. Fifteen patients with TTP (190 procedures) and ten MG patients seen concurrently were studied. While baseline bicarbonate levels were similar among all patients, the post\u2010procedure bicarbonate levels in TTP patients were mostly elevated with a mean \u00b1 SD of 29.4 \u00b1 3.5 mEq\/L, as opposed to decreased or unchanged in MG patients 26.3 \u00b1 3.1 mEq\/L (mean \u00b1 SD) (<jats:italic>P<\/jats:italic> = 1.4 \u00d7 10<jats:sup>\u22128<\/jats:sup>). Furthermore, alkalosis in the TTP group persisted throughout subsequent daily treatments. There was also a significant decrease between pre\u2010 and post\u2010TPE potassium levels in TTP patients (<jats:italic>P<\/jats:italic> = 3 \u00d7 10<jats:sup>\u221221<\/jats:sup>) by paired Student's t test. Additionally, samples with levels &lt;3.3 mEq\/L were alkalotic 75% of the time. In the MG group, however, potassium was normal in 85% and 83% of the pre\u2010 and post\u2010TPE samples, respectively. Consequently, the hypokalemia was significantly more marked in the TTP group (<jats:italic>P<\/jats:italic> = 0.0008). These data confirm that plasmapheresis commonly induces metabolic alkalosis in TTP patients, probably due to high citrate in fresh frozen plasma, the frequency of treatments, and perhaps decreased renal clearance due to disease involvement of the kidneys.
