Cytopathic effects and local immune responses in repeated neoadjuvant HSV-tk + ganciclovir gene therapy for prostate cancer

ObjectiveCytopathic effects and local immune response were analyzed histologically in prostatic carcinoma (PCa) with in situ herpes simplex virus-thymidine kinase (HSV-tk)/ganciclovir (GCV) gene therapy (GT). MethodsFour high-risk PCa patients who received HSV-tk/GCV GT were investigated. After two cycles of intraprostatic injection of HSV-tk and administration of GCV, radical prostatectomy was performed. Formalin-fixed, paraffin-embedded sections were evaluated using immunohistochemistry. PCa with hormone therapy (HT, n = 3) or without neoadjuvant therapy (NT, n = 4) that were equivalent in terms of risk were also examined as reference. Immunoreactively-positive cells were counted in at least three areas in cancer tissue. Labeling indices (LI) were calculated as percentage values. ResultsssDNA LI in GT increased, indicating apoptosis, as well as tumor-infiltrating lymphocytes and CD68-positive macrophages, compared with their biopsies. GT cases showed significantly higher numbers of ssDNA LI, CD4/CD8-positive T cells and CD68-positive macrophages including M1/M2 macrophages than HT or NT cases. However, there was no significant difference in CD20-positive B cells among the types of case. There were strong correlations between CD8+ T cells and CD68+ macrophages (ρ = 0.656, p < 0.0001) as well as CD4+ T cells and CD20+ B cells (ρ = 0.644, p < 0.0001) in PCa with GT. ConclusionsEnhanced cytopathic effect and local immune response were might be indicated in PCa patients with HSV-tk/GCV gene therapy.Cytopathic effects and local immune response were analyzed histologically in prostatic carcinoma (PCa) with in situ herpes simplex virus-thymidine kinase (HSV-tk)/ganciclovir (GCV) gene therapy (GT..

Rinsing of oropharynx and storage place of respiratory medicine inhaler: A cross‐sectional audit

BackgroundIn patients with bronchial asthma and those with chronic obstructive pulmonary disease (COPD), inhalation therapy and rinsing of the mouth and the oropharynx by gargling (“RMOG”) after inhalation are recommended. We performed a cross‐sectional audit aimed at investigating (a) the proportion of patients performing “RMOG” after inhalation and (b) storage place of patients’ inhaler.MethodsPatients with bronchial asthma and those with COPD were asked by medical aids at outpatient visits whether they did “RMOG every time,” “RMOG sometimes,” or “no RMOG” after inhalation, and where they stored their inhaler.ResultsDuring a six month study period up to September 2017, 330 consecutive patients with asthma and those with COPD were included in the study. Two hundred and thirty‐two (70.3%) of the 330 patients answered “RMOG every time” and 98 (29.7%) of them did “RMOG sometimes” and did “no RMOG.” There was a difference in the proportion of patients performing RMOG after inhalation with patient age. With regard to the storage location of inhaler, we found the proportion of patients performing RMOG was higher in those who stored inhalers in a room with running water than in those who stored inhalers at other places. This difference was found in patients with both bronchial asthma and those with COPD.ConclusionsFurther implementation of “patient education” on performing RMOG after inhalation for patients receiving inhaled medication is still necessary. Our results suggest that it is better to store inhalers in places where there is easy access to tap water used for RMOG
