AbstractAdult respiratory distress syndrome is a severe respiratory failure due to noncardiogenic pulmonary edema with high mortality rates (50-70%). The most common etiology of respiratory distress is sepsis, but it may also be caused by several of the immunosuppressants prescribed in transplantation. In the last year, influenza H1N1 virus infection has become more relevant. It has shown a greater incidence among immunosuppressed patients as well as those with chronic kidney disease or diabetes mellitus. We present the case of a patient with simultaneous pancreas-kidney transplantation who presented respiratory distress after the second dose of thymoglobulin. Initially, we interpreted that the thymoglobulin was the cause, so it was replaced with basiliximab. Empirical treatment was started with 3 doses of 6-methylprednisolone (250 mg), with a favorable response. After 7 days, we received the results of the reverse-transcriptase polymerase chain reaction of a nasal smear and blood culture, which were positive for H1N1 virus. In our knowledge, this is the first reported case of a patient with simultaneous pancreas-kidney transplantation and respiratory distress secondary to H1N1 virus infection who showed a favorable response to corticosteroid therapy.
