Double lung transplantation for Sjogren's syndrome-related interstitial lung disease: a case report and review of literature

In this study, we present a case of 65-year-old male patient with suspected Sjogren's syndrome -related interstitial lung disease (SS-ILD) with initial symptoms of limb edema and acute respiratory failure. He was treated with immunosuppressor, respiratory support, dialysis, immunomodulatory, and anti-inflammatory medications. However, no significant response was shown to anti-fibrotic treatments and his respiratory function deteriorated. Double lung transplantation was thus indicated considering the irreversible interstitial changes in both lungs. The surgical procedure was complicated, and the role of enhanced recovery after surgery (ERAS) for this critical patient was discussed. The patient experienced hemorrhage, pulmonary infection, and peripheral neuropathy after surgery, but he was cured by the multidisciplinary team. He had a satisfactory quality of life at 1-year follow-up. This case report describes the details of double lung transplantation in a patient with advanced SS-ILD. Important considerations include the indications for and timing of transplantation, the effects of long-term immunosuppression on wound healing, and extrapulmonary organ dysfunction. Based on a review of the published literature and a consideration of the short-term outcomes, lung transplantation for this individual with an autoimmune disease appears to be safe and feasible. SS-ILD should not be a contraindication to transplantation; however, patients with advanced pulmonary involvement should be carefully selected after a multidisciplinary evaluation. More long-term follow-up and further comparative studies are needed in the future.
