Investigation the efficacy of antipsoriatic drugs by blood plasma thermoanalysis

Abstract

AbstractPsoriasis is an immune cell-mediated mainly inflammatory skin disease where patients may become asymptomatic after systemic drug therapies or nevertheless mild-to-moderate symptoms or exacerbating of either severe symptom should be detected. In addition to know the general change of blood plasma, the aim of the recent study was to detect the effect of antipsoriatic drug treatment to the patients’ symptoms by differential scanning calorimetry (DSC). The study included patients of both sexes who had different symptoms despite treatment with antipsoriatic medication (cytostatic agents, retinoids, biological treatment, n = 10 in each group). After the examination by dermatologist, the definition of symptoms severity was established on PASI (Psoriasis Area Severity Index) score. Blood plasma calorimetric changes were measured with calorimeter device. In the examined psoriatic patients, the thermodynamic parameters: denaturation temperature and calorimetric enthalpy of the transitions in proportion, corresponded to the degree of disease severity after targeted treatments with cytostatic or retinoid agents or following biological response modifier therapy. In conclusion, plasma DSC profiles were associated with response to antipsoriatic agents, which was associated with the presence or absence of symptoms after treatment.
