Estudio descriptivo de actividad del banco y registro de donantes de médula ósea de la región de Murcia (sureste de España) (1994-2004) / Descriptive study of activity of the bone marrow donor registry and bank from the Murcia region (Southeast of Spain) (1994-2004)

Objetivo: Realizar un estudio descriptivo de la actividad del banco y registro de donantes de médula ósea de la región de Murcia. Sujetos y método: Constituido por los donantes disponibles en el Banco de médula desde 1994 hasta 2004 (n = 3137). El estudio consiste en un análisis del número de donantes, su procedencia y, las búsquedas realizadas. Los donantes se tiparon por técnicas serológicas de microlinfocitoxicidad, y moleculares de PCR-SSO y -SSP. Resultados: El banco dispone de 3.137 donantes voluntarios tipados en baja y alta resolución, realizando un total de 680 búsquedas de donante. La procedencia de los donantes según las áreas de salud en que esta dividida la Comunidad de Murcia fue: área I (28%), área II (18%), área III (23%), área IV (6%), área VI (10%) y otras provincias (12%). Conclusiones: Observamos un aumento exponencial del número de donantes anuales, así como un aumento muy notable de las búsquedas por año, especialmente el 2004

Objective: To perform a descriptive study of the activity of the Bank of marrow donors from Murcia Region. Subjects and methods: All donors in the Bank of bone marrow from 1994 until 2004 (n=3137). This study analysed the number of donors, their origin and, performed donor searches activity. Donors were typed by serological microlymphocytotoxicity and molecular PCR-SSO and PCR-SSP techniques. Results: The Bank of bone marrow has 3,137 voluntary donors typed in low- and high-resolution. A total of 680 donor searches have been realized. The origin of the donors according to several Areas of Health in which the Autonomous Community of Murcia is divided, is the following one: Area I (28%), Area II (18 %), Area III (23 %), Area IV (6 %), Area VI (10 %) and other provinces (12%). Conclusions: An increase is observed in the number of annual donors as well as an increase very marked of donor searches that are realized every year, especially in 2004

Serum soluble interleukin-2 receptor: a useful indicator of the clinical course in pulmonary tuberculosis.

SETTING: In tuberculosis both host protection and most pathogenic mechanisms depend on T lymphocytes. After activation by mycobacterial antigens, T cells both secrete interleukin-2 (IL-2) and express a high affinity receptor for this molecule (IL-2R) on their own surface. A soluble fraction of IL-2 receptor (sIL-2R), released from cell membrane, is detectable in serum and its concentration is known to be elevated in tuberculosis. OBJECTIVE: To ascertain the role of sIL-2R as an indicator of clinical evolution and response to antituberculosis treatment. DESIGN: A prospective study, in which we have measured serum sIL-2R in 52 patients (42 with active and 10 with inactive pulmonary tuberculosis) and in 36 healthy controls. In 20 patients, serum sIL-2R levels were measured serially throughout the treatment. Levels of sIL-2R were correlated to clinical and radiological parameters. RESULTS: Serum sIL-2R was significantly increased in patients with tuberculosis as compared to healthy subjects. Both the radiological findings and the clinical state of patients showed a good correlation with sIL-2R. All patients with normal values of sIL-2R 6 months after starting therapy had a favourable clinical evolution. CONCLUSION: Serum sIL-2R is a useful marker of the clinical state and evolution of patients with pulmonary tuberculosis. The detection of permanently high values beyond 3-6 months of treatment suggests that additional drugs or prolonged administration would be advisable in order to ensure full recovery.
