[The condition of intestinal microflora in patients with hematologic tumors receiving polychemotherapy]

The subjects of the study (105 patients with blood system tumors), were divided into 4 groups. The patients of the first group received only cytostatic therapy. The subjects of the second, third and fourth groups were administered a combination of cytostatic and antibacterial agents. In addition to this, the patients of the third and fourth groups received prebiotic preparations as means of corrective therapy. The results obtained by measurement of short-chain fatty acids (SCFA) in feces by means of liquid-gas chromatography were used as criteria for evaluation of the therapy influence on intestinal microflora. The study shows that the cytostatic and combined treatment worsen the disbalance between aerobe and anaerobe populations, which manifests in SCFA spectrum alteration. Use of prebiotic preparations results in improvement of intestinal microflora condition or prevents the aggravation of its disturbance caused by the treatment of the fundamental illness, which becomes apparent in stabilization or normalization of SCFA profile in feces. Study of SCFA makes it possible to monitor microbiocenosis, adjust corrective therapy individually and evaluate its effectiveness.
