Clinical significance of sodium-dependent lithium transport in affective psychoses.
The steady state red blood cell/plasma lithium (Li) ratios were determined simultaneously with the in vitro rates of sodium-dependent Li transport of erythrocytes during prophylactic Li therapy in 30 unipolar, 52 bipolar forms of manic-depressive patients and in 58 nonmanic-depressive psychiatric patients as a control group. A reciprocal correlation was found between the Li ratios and the values of Na-dependent Li transport. These transport rates were in positive correlation with the steady state Li contents of red blood cells and that of the plasma. Significant differences were revealed between the different nosologic subgroups in the respect of in vitro rates of Na-dependent Li countertransport. Results are discussed in the light of clinical and pharmacogenetic aspects.
