The influence of low-intensity laser irradiation of blood on the lactoferrin level in the patients presenting with community-acquired pneumonia

Abstract

The objective of the present study was to estimate the influence of low-intensity laser irradiation of blood on the levels of lactoferrin in the patients presenting with community-acquired pneumonia. All the patients were divided into two groups. Those comprising the control group received only medicamental therapy. The standard treatment of the patients in the second group was supplemented by intravenous laser irradiation of blood (IVLIB-405 technique). Each irradiation session performed in a continuous mode lasted 5-7 minutes, with the total treatment course consisting of 7 daily procedures. Lactoferrin was determined before and after the treatment by the enzyme immunoassay with the use of "Lactoferrin Strip" kits ("Vektor-Best- Yug" JSC, Russia). Analysis of the results of the study revealed a significant decrease in the blood lactoferrin level down to the normal range in the patients treated with the use of laser therapy. The application of intravenous laser irradiation of blood for the combined treatment of the patients with community-acquired pneumonia was accompanied by normalization of the blood lactoferrin level and the improvement of the clinical course of the disease.
