Abstract:
Objective To analyze the characteristics of tuberculosis (TB) in renal-transplant recipients from our hospital, and summarize the corresponding experiences in diagnosis and management.Methods A retrospective study was performed on 61 documented post-transplant TB cases out of the 2842 patients who received kidney transplantation in the First Affiliated Hospital of Sun Yat-sen University between Jan.1991 and Dec.2010.Results TB in the post-renal-transplant population in our hospital displayed the following characteristics:(1) High incidence (2.1％ ).54.1％ recipients were diagnosed within the first year post-transplant; (2) Lung was the most common site (77.0 ％).There was high prevalence (60.7 ％) of extra-pulmonary TB (lymphatic TB,23.0 ％; pleuritis,13.1 ％; graft,11.5％); (3) Fever (83.6 ％),cough (55.7 ％),sputum (41.0 ％) were the most common clinical manifestations.There were also emaciation (3.3 ％) and enlargement of lymph nodes (18.0 ％); (4) Chest X-ray and CT were of great value during TB diagnosis while purified protein derivative of tuberculin (PPD) skin test had little diagnostic value with a negative result in 56 cases (91.8 ％) ; (5) Liver function damage ( 16.4 ％),kidney function injury (39.3 ％) and peripheral nerve toxicity (3.3 ％) were the main adverse reactions of anti-tuberculosis chemotherapy,also the major cause of anti-TB failure; (6) Pre-transplant TB (17 cases) increased the probability of TB recurrence (4 cases,23.5 ％) post-transplantation; (7) The post-transplant TB patients were accompanied with cellular immune deficiency,resulting in overlapping infection of bacteria,viruses and fungi (19.7 ％); (8) 1- and 3-year patient/graft survival rate of patients with post-transplant TB was 85.2 ％/78.7 ％ and 85.2 ％/75.4 ％ respectively. The accumulative mortality rate reached to 14.8％,while overlapping infection was the major cause of death (66.7 ％).Conclusion Chinese renal transplant recipients still face a high risk of TB because of their immunecompromised state and epidemiological prevalence of the disease. For the high mortality rate and associated serious complications,rapid diagnosis and effective anti-TB chemotherapy are of great value for TB population.
