Mesenchymal stromal cells application for experimental genital tuberculosis combination therapy

Abstract

BACKGROUND: Cell therapy is a promising trend in treating characterized by inflammation and sclerosis diseases such as genital tuberculosis, marked by pelvic inflammatory disease and uterine tube occlusion.
 AIM: Efficacy evaluation of combined mesenchymal stem cells and specific polychemotherapy treatment of the experimental genital tuberculosis.
 MATERIALS AND METHODS: Chinchilla rabbits (n = 27) were divided on 4 groups. Group 1 (n = 6) comprised control group, healthy animals. Group 2 (n = 7) infected with genital tuberculosis, without treatment. Group 3 (n = 7) infected with genital tuberculosis, treated with anti-tuberculous drugs only. Group 4 (n = 7) infected with genital tuberculosis, treated with anti-tuberculous drugs and mesenchymal stem cells. Culture of M. tuberculosis Erdman in dose 107 CFU/0.2 ml was injected under the left uterine tube serosa for the genital tuberculosis modelling. For treatment efficacy evaluation following tests were used: full blood count, blood chemistry, hysterosalpingography, diagnostic laparoscopy, peritoneal macrophage phagocytic activity assessment.
 RESULTS: Infected with genital tuberculosis animals had leukocytosis, elevated C-reactive protein, swelled and occluded uterine tubes. Treated with anti-tuberculous drugs and mesenchymal stem cells rabbits had lower white blood cell count (8.18 1.39 109/L vs 9.32 1.36 109/L, р 0.05) and C-reactive protein (1.1 0.8 mg/L vs 2.2 1.2 mg/L, р 0.01) compared to animal treated with anti-tuberculous drugs only. Animals in group 4 had also increased peritoneal macrophage phagocytic activity. Treated with mesenchymal stem cells animals had unobstructed uterine tubes, stabilized adhesive process within small pelvis with reparative process prevalence.
 CONCLUSIONS: Mesenchymal stem cells combined with anti-tuberculous drugs therapy favors reparative process in uterine tubes in genital tuberculosis.
