Why does the pulmonary infection rate for lung transplantation appear to be higher than with other solid organ transplants?

Question

Quizplus · Accepted Answer

Although pulmonary infections are common because of the immunosuppression required with any solid organ transplant, the pulmonary infection rate for lung transplantation appears to be high. This may be partially explained by the fact that the lung is the only solid organ that, after transplantation, is regularly in direct contact with the external environment and multiple potential pathogens. Many pulmonary bacterial infections are readily identified but often require bronchoalveolar lavage (BAL) and culture for accurate diagnosis and treatment with antibiotics.
