RESUMO
AIM: The objective of the present study was to elucidate the influence of low-intensity laser radiation on the results of the nitroblue tetrazolium (NBT) test in the patients presenting with community-acquired pneumonia. PATIENTS AND METHODS: A total of 100 patients with community-acquired pneumonia were available for the examination of whom 70 were treated with intravenous low-intensity laser irradiation of blood (ILIB) by means of the ILIB-405 technique during 7 days. The functional activity of neutrophils was estimated from their ability to reduce nitroblue tetrazolium in both spontaneous and stimulated NBT-tests. RESULTS: The analysis of the data obtained in the study has demonstrated the significant improvement of the results of the NBT tests in the group of patients receiving the ILIB treatments regardless of whether its content was originally elevated or reduced. CONCLUSION: The inclusion of intravenous low-intensity laser irradiation of blood in the combined treatment of the patients with community-acquired pneumonia appreciably promotes normalization of the bactericidal activity of neutrophils.

UNLABELLED: 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. MATERIALS AND METHODS: 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). RESULTS: 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. CONCLUSION: 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.
