Summary

In this clinical trial study, 60 patients with GvHD referred to Shahid Qazi Hospital in Tabriz, were randomly divided into 2 intervention and control groups (n= 30 in each) that received secretome and distilled water by injection, respectively. The method of blinding was triple-blinded and all the names and personal information of the patients were coded at the time of data collection and remained completely confidential.

Detailed description

This study is a safety, feasibility, and efficacy trial that was conducted on eligible GvHD patients with the diagnosis of expert doctors after obtaining permission from the respected ethics committee and registering the trial at the Iranian Trial Registration Center. During the phone call, while stating the title and objectives of the study, the entry and exclusion criteria were checked.

The written informed consent was obtained and questionnaires fulfilled three times which include personal-social characteristics, medical characteristics, appetite questionnaire, 24-hour food record (Food record), and family members. At the beginning of the study, 50 cc of blood was used to collect serum and to culture and condition mesenchymal stem cells. 200 men with GvHD were randomly assigned using random block method using blocks of 4 and 6 and RAS (Random Allocation Software) and allocation ratio 1:1 to two groups receiving intravenous secretome with The first protocol (30 people) and receiving the mesenchymal stem cells secretome of the second protocol (30 people) were allocated and they received the skin spray for 1 year. Participants in the first protocol group at the beginning of the study, day 3, end of the week, the end of the second week, and the end of the month 5 times and in the second protocol group at the beginning of the study, skin spray were done. The secretome of both groups was the same.
