This volume is based on a very successful meeting on organ transplantation that was held in Kuwait in 1990 under the auspices of the Middle East Society for Organ Transplantation. An international group of organ transplant experts attended this conference and their contributions and deliberations have been recent1y updated to produce this definitive and authoritative summary of current clinic al practice in organ transplantation. The initial chapters appropriately focus on the immunology of organ trans­ plantation with special emphasis on the initial events in the induction of alloreactivity, the mechanisms of rejection, and the potential for tolerance induction. A strong emphasis is placed on the diagnosis of rejection by cellular analysis. The section on immunosuppression deals with several new areas of clinical therapy. The section on renal transplantation is unique in several respects, the long-term results from various countries, including the Middle East, are summarized, the use of living unrelated donors and of ABO incom­ patible donors - all strategies to maximize organ availability - are presented.
