Lithium is a typical treatment prescribed to sufferers with psychiatric issues, particularly bipolar dysfunction, schizophrenia, and despair. It’s used as a temper stabilizer and lessens the depth of manic episodes, with explicit profit in decreasing suicidality. Whereas extremely efficient, the drug requires routine blood monitoring, which will be uncomfortable, costly, and inconvenient for sufferers who should journey to scientific labs for frequent blood testing.

Analysis from the College of California, Irvine’s Institute for Interdisciplinary Salivary Bioscience (IISBR) factors to saliva testing as a possible various to blood sampling. In comparison with blood, saliva assortment is simpler, non-invasive, requires much less processing, and will be carried out in any setting.

A latest examine printed within the worldwide journal Bipolar Problems confirmed a excessive correlation between saliva and serum lithium ranges and that saliva-serum ratio inside a person might robustly predict a affected person’s serum lithium stage. These findings recommend that saliva might actually be used for lithium monitoring amongst sufferers with temper issues.

Over the course of 18 months, researchers collected 171 saliva samples from 75 sufferers with identified bipolar dysfunction, schizophrenia, schizoaffective dysfunction, main depressive dysfunction, or generalized anxiousness dysfunction.

Findings from the examine will fill important gaps in literature on the efficacy of saliva for drug monitoring. Whereas a big physique of labor courting again 30 years does exist, pattern sizes have been small, strategies have been various, and older strategies have been used. The examine, in addition to the continued work being carried out at IISBR, will open the door for the event and implementation of novel salivary testing strategies, which is able to undoubtedly enhance therapy choices for sufferers taking lithium drugs, in addition to the psychiatric affected person expertise general.

Co-investigators of the examine embrace UCI Public Well being epidemiology doctoral pupil and corresponding creator Georgia Parkin; UCI Public Well being and IISBR epidemiology researcher Elizabeth A. Thomas, Ph.D.; IISBR laboratory supervisor Hillary Piccerillo; and professor emeritus and former IISBR director Douglas A. Granger, Ph.D.
