Ethical Guideline for Researches on Tissue and Organ Transplantation:

Introduction
Considering the ever-increasing and multilateral approach to development and advancement of the transplantation in Iran and noting the recent technical and scientific advancements in this regard, and emphasizing on the necessity of scientific researches in this field, observing of the ethical principles in such researches is evident and essential. Human tissues and organs can be used for therapeutic, educational and research purposes. This guideline mentions to the essential ethical principles which should be considered in the researches on tissue and organ transplantation. This ethical guideline consists of two parts containing general and special articles.

General Guideline
Researches on tissue and organ transplantation are researches using human materials aimed to advancement of the science of transplantation. Human materials include organ, tissue, endocrine secretions, or waist material of alive or dead body, fetus, or placenta.
1- All researches in the field of tissue or organ transplantation should be done whit consideration of all of the articles of "The Ethical Guideline for Researches on Tissue and Organ Transplantation".
2- The purpose of research should be scientific advancement and in accordance with the goals of national health system, and should not be for financial or commercial purposes.
3- All researches in the field of tissue or organ transplantation should be approved by the related ethical committees of the university or research center.
Note: Ethical surveillance and assessment of the ethical committees with regular time intervals and thorough the course of research is essential.
4- For ethical approval, all donations of organs should be made with the donor's informed consent
Note: The obtained consent should be based on the research purposes.
5- Interests and requests of the participant(s) should be placed above those of researchers.
Note: In special conditions in which the public health depends on such researches, and avoiding of such researches would be harmful for the community, such researches may be done with approval of the national committee of research ethics.
6- All of personal information obtained from the participants in the research, and gathered and recorded through the course of research, should be considered confidential, and confidentiality should be observed according to the related articles in the " General Guideline of Ethics in Research"
7- Appropriate tests and screening should be performed on the donor and donated organs for preventing of transmission of infectious diseases.
8- No cost should be imposed to the donor in any stages of the research.
9- The researcher or the sponsor organization should compensate any possible harm. Including physical, financial or spiritual harms, to the participant in transplantation research, according to domestic law and opinion of related authorities.
10- An agreement regarding the mean and level of informing the participants about the results of the research should be made and mentioned in the consent.
11- Some transplantation researches may result in invention or production of therapeutic products or techniques which could be used commercially. Therefore, copy right of research results should be approved and supported.
12- In addition to considering all of ethical principles. The research should be conducted only by scientifically and technically qualified team and the center or organization in which the research is being conducted should have appropriate facilities for research and prevention and treatment of possible complications.
13- Sending tissues or organs to foreign countries for common researches, is permitted only with approval of the “National Committee of Research Ethics”.
Note 1: Common researcher with foreigner financial or scientific sponsor, if do not require sending tissues or organs to foreign countries, are permitted.
Note 2: For using the tissues or organs of foreigner persons in transplantation researches, the Approval of the “National Committee of Research Ethics” is necessary.
14- The researcher should use the organs and tissues which are dedicated to research and should not dismiss them. If any kind of carelessness is proven, the researcher should compensate the possible losses.
15- Considering the shortage of organ and tissue for transplantation in Iran, the therapeutic uses should take priority and research uses should not reduce the rate and quality of the therapeutic uses.
16- For using of tissues and organs stored in the tissue and organ banks, the donor should permitted the research use in the consent.
Note: If the donor did not mentioned to the means of use, it can be used for research purposes, only if there is no request for therapeutic use.

Special Guidelines


Chapter 1: Cadaver Donor Transplantation
1-1- In the cases of using of the organs or tissues of dead persons for transplantation, its necessity should be approved by the ethics committee.
Note1: Currently, the system of obtaining consent for using the cadaver for research in Iran is based on opting-in.
