[Is cholesterol lowering following UVA blood irradiation an effect of citrate?]

On 92 patients the effect of the UV irradiation of blood on the blood parameters is studied. In the blood picture a decrease of leucocytes and reticulocytes is observed, in which case the latter is in connection with the decrease of blood and not with the UVA irradiation. In test persons with increased cholesterol level after UVA therapy as well as after a mere citrate infusion (anticoagulancy) during four weeks highly significant decrease of the cholesterol level, above all of the LDL-cholesterol appears. HDL cholesterol and triglycerides are not influenced. The decrease of cholesterol by citrate infusion is discussed and it is referred to possible therapeutic consequences.
