Abstract

Objective:

This is a random blinded placebo controlled murine experimental model to study the effects of Cantharis 6 CH, a homeopathic medicine, on E coli-induced cystitis.

Methods:

24 adult susceptible female BALB/c mice were inoculated with E coli – UPEC O4:K-:H5 by a transurethral catheter. Cantharis 6cH or vehicle (placebo) was offered to mice by free access into the drinking water (1:100), during 24 h after infection. Spleen, bladder and kidneys were processed for quantitative histopathology after immunohistochemistry, using anti-CD3, CD79, MIF, NK and VEGF antibodies; the cytokines present in the bladder washing fluid were measured using a LUMINEX-Magpix KIT. Mann-Whitney and Fisher exact test were used as statistical analysis.

Results:

Cantharis 6 CH increased IL12p40, IFN-γ and decreased IL10 concentrations in the bladder fluid (p ≤ 0.05); in the bladder mucosa, it increased the ratio between B and T lymphocytes (31%) and between B lymphocytes and MIF+ macrophages (57%, p ≤ 0.05). In the pelvis, instead, it decreased the B/T cells ratio (41%, p ≤ 0.05) and increased the M1/M2 macrophage ratio (42%, p ≤ 0.05). No differences were seen in the kidney and spleen analysis.

Conclusion:

The inverted balance of inflammatory cells and cytokines in bladder and pelvis mucosa shows specific local immune modulation induced by Cantharis 6cH.
