Early Indicators of Chronic Rejection in Lung Transplant

2014-07-24 14:22:00 | BioPortfolio

Summary

The purpose of this research is to discover the different patterns of cytokine production in patients who may develop Bronchiolitis Obliterans Syndrome-0p (BOS-0p) which means ongoing rejection. This is an early indicator of chronic rejection in lung transplant recipients. These cytokines can be detected in the bronchoalveolar (lung) and tissue samples of lung transplant recipients.

Description

Lung transplant recipients are routinely followed in clinic every three months after the first year post-transplant. Spirometry with measurement of FEV1, FVC and FEF25-75 are obtained at each visit. In addition, lung transplant recipients undergo surveillance bronchoscopy at one, three, six, nine and twelve months. All bronchoscopy specimens that are obtained for this study will be obtained during bronchoscopies that were scheduled per the physician caring for the patient. An extra 90 cc of sterile solution will be instilled into bronchus and two extra transbronchial biopsies will be performed in addition to the routine bronchoscopic procedure. Routinely, 4-8 transbronchial biopsy samples are obtained from the transplanted lung. Two specimens will be randomly selected for study and the rest will undergo routine histopathologic study. The study biopsies will be set aside and processed. The study visits for this research will occur at the same time as standard of care post transplant visits. We will collect subject's history,demographic of subject's transplant data,donor procurement information, physical exam information, pregnancy tests,blood test and spirometry results from the visits mentioned above.

Medical and Biotech [MESH] Definitions

An immune response with both cellular and humoral components, directed against an allogeneic transplant, whose tissue antigens are not compatible with those of the recipient.

A derivative of sirolimus and an inhibitor of TOR SERINE-THREONINE KINASES. It is used to prevent GRAFT REJECTION in heart and kidney transplant patients by blocking cell proliferation signals. It is also an ANTINEOPLASTIC AGENT.

Identification of the major histocompatibility antigens of transplant DONORS and potential recipients, usually by serological tests. Donor and recipient pairs should be of identical ABO blood group, and in addition should be matched as closely as possible for HISTOCOMPATIBILITY ANTIGENS in order to minimize the likelihood of allograft rejection. (King, Dictionary of Genetics, 4th ed)

A group of antigens that includes both the major and minor histocompatibility antigens. The former are genetically determined by the major histocompatibility complex. They determine tissue type for transplantation and cause allograft rejections. The latter are systems of allelic alloantigens that can cause weak transplant rejection.

Any disorder marked by obstruction of conducting airways of the lung. AIRWAY OBSTRUCTION may be acute, chronic, intermittent, or persistent.
