The experience of the Republic of Cuba regarding epidemiological studies, integral medical care, and strategies for the prevention of chronic kidney disease is summarized in this report. Cuba has a National Program for Chronic Renal Disease, Dialysis, and Renal Transplantation. There is a national nephrology net, integrated by the Institute of Nephrology as the coordinator center, that has 47 nephrology services with a hemodialysis unit (24 of them with peritoneal dialysis unit), 9 transplantation centers, 33 organ procurement hospitals, and 5 histocompatibility laboratories. In 2004, the incidence rate in dialysis patients was 111 pmp, and the prevalence rate was 149 pmp, demonstrating an increasing mean of 17.0% and 10.0% per year, respectively. Renal transplantation rate was 16.6 pmp. The detection, registration, and follow-up of patients with chronic kidney disease (serum creatinine > or =1.5 mg/dL or glomerular filtration rate <60 mL/min) by family doctors was 9,761 patients, 0.87 patients per 1,000 inhabitants. In the 1980s, three population-based screening studies were performed to define the burden of chronic renal failure in different regions of Cuba. The prevalence rate was 1.1, 3.3, and 3.5 per 1,000 inhabitants, respectively. At present, another three population-based screening studies are ongoing in order to detect the chronic kidney disease in earliest stages. The continuing medical education activities have been very useful in raising the awareness of medical doctors and the basic health staff about the threats posed by and the strategies to prevent, diagnose, and treat chronic kidney disease.
This article describes the background, beginnings, development, evolution and outcomes of kidney transplantation in Cuba. Nephrology as a medical specialty in Cuba began in 1962 and was formalized in 1966. Conditions were created to implement renal replacement therapy (including transplants), bring nephrology care to the entire country and train human resources who would assume this responsibility, making Cuba one of the first countries with a comprehensive program for renal patient care. After three unsuccessful cadaveric-donor kidney transplantations in 1968-69, the ensuing history of kidney transplantation can be summarized in the following three stages. 1970-1975: In January 1970, cadaveric-donor kidney transplantation began at the Nephrology Institute. That year, 17 kidney transplantations were performed; four of these patients lived with functional kidneys for 15-25 years; 10-year graft survival was 23.5% (Kaplan-Meier survival curve); HLA typing began in 1974. By December 1975, 170 grafts had been done in three hospitals. 1976-1985: Seven transplantation centers performed 893 grafts during this period. HLA-DR typing was introduced in 1976 and the National Histocompatibility Laboratory Network was founded in 1978. The first related living-donor kidney transplantation was done in 1979. 1986-2011: The National Kidney Transplantation Coordinating Center and the National Kidney Transplantation Program were created in 1986; the first combined kidney-pancreas transplantation was performed the same year. In 1990, cyclosporine and the Cuban monoclonal antibody IOR-T3 were introduced for immunosuppression to prevent rejection, as were other Cuban products (hepatitis B vaccine and recombinant human erythropoietin) for transplant patients. By December 2011, the cumulative number of transplants was 4636 (384 from related living donors). With over 40 years of experience, kidney transplantation is now well established in Cuba; it is free and universally accessible, on the basis of need and appropriateness.
