    Abstract:
    OBJECTIVES: To analyze the characteristics of tuberculosis (TB) in Southern Chinese renal transplant recipients, and summarize the corresponding experiences in diagnosis and management. METHOD: Retrospectively study 41 documented post-transplant TB cases out of the 2333 patients who received kidney transplantation in the First Affiliated Hospital of Sun Yat-sen University between Jan. 1991 and Apr. 2007. RESULTS: TB in the post-renal-transplant population in Southern China displayed the following characteristics: (i) high incidence within a short time after transplantation, the median interval between renal transplantation and diagnosis of TB was 8 months (range: 1-156 months) and 56.1% were diagnosed within the first year post-transplant; (ii) high prevalence (51.2%) of extra-pulmonary tuberculosis; (iii) high co-infection rate (19.5%), pathogens included candida albicans, pseudomonas aeruginosa, staphylococcus aureus, Acinetobacter haemolyticus and cytomegalovirus; (iv) fever (82.9%), cough (56.1%) and sputum (39.0%) are the most common clinical manifestations; (v) purified protein derivative of tuberculin (PPD) skin test had little diagnostic value in this group with a negative result in all 41 cases; (vi) acute rejection (29.3%) and liver function damage (17.1%) were the main adverse effects of anti-tuberculosis chemotherapy; (vii) mortality of patients with post-transplant tuberculosis reached up to 22.0%. CONCLUSIONS: Chinese renal transplant recipients face a high risk of TB because of their immuno-compromised state and epidemiological prevalence of the disease. Therefore, attention should be given to this differential diagnosis in clinical practice. Balancing the benefits and disadvantages of anti-tuberculosis chemotherapy is of importance for this specific population.
