Lymphotropic administration of photosensitizer as a model of target therapy of testicle inflammation: Experimental and clinical data

• Lymphotropic therapy for testicle inflammation—target therapy.
• Lymphotropic therapy allows for protracted presence of drug in target organs.
• Fluorescence spectroscopy is used for detection of photosensitizer distribution in organs.
• Humoral connection of cutaneous tissue with testicles is proved.

BackgroundThe existence of zones of humoral skin–subskin tissue linkage with internal organs as well as the possibility of targeted administration of preparation into the affected organs were studied.MethodsAn experimental study of preparation and distribution in the bodies of mice was held by both intravenous and lymphotropic methods of administration. By means of detection with a photosensitizer (as a marker), the study was conducted on healthy mice and mice with testicle inflammation.Based on the experimental results, the study has been implemented into the clinical practice of treatment of acute inflammatory diseases of testicle and its epididymis. Patients were administered antibiotics either by the lymphotropic method, or by traditional methods.ResultsThe concentration of the preparation, administered by the lymphotropic method, maintained in target organs (testicles) at a high level for a longer time, while the intravenous injections provided fast achievement of high concentrations. Moreover there was a lower level of accumulation of the photosensitizer in parenchymal organs after subcutaneous (lymphotropic) administration.ConclusionsThe presence of humoral connection of certain areas of skin and subcutaneous tissue with testicles and their epididymis was proved. It was found that the lymphotropic administration leads to earlier clinical improvement and normalization of laboratory indices, and, thus, to significant reduction in hospital stay. Such results open the possibility of targeted drug delivery to the diseased organs. In perspective, the method may be used in treating patients not only in urology, but also in surgery, as well as for many acute, chronic or cancer diseases.
