Bilateral Pulmonary Nodules After Lung Transplantation: A Rare Diagnosis

Also, because of calcineurin inhibitor (CNI)-related renal dysfunction, the patient's immunosuppression was converted to a belatacept-based CNI-sparing regimen in addition to prednisone, with a tacrolimus goal trough of 4 to 6 ng/mL.

Current Standard

Conventional pulmonology practice relies on standard-of-care monitoring and existing regimens prior to this clinical case insight.

New Finding

Antibody-mediated rejection was successfully treated with our institutional multimodal regimen, including a combination of plasmapheresis, carfilzomib, and anti-thymocyte globulin followed by monthly IV immunoglobulin and tocilizumab injections.

What This Means for You

Antibody-mediated rejection was successfully treated with our institutional multimodal regimen, including a combination of plasmapheresis, carfilzomib, and anti-thymocyte globulin followed by monthly IV immunoglobulin and tocilizumab injections. Also, because of calcineurin inhibitor (CNI)-related renal dysfunction, the patient's immunosuppression was converted to a belatacept-based CNI-sparing regimen in addition to prednisone, with a tacrolimus goal trough of 4 to 6 ng/mL. He was also placed on mycophenolic acid, which was soon held because of neutropenia.

The Discovery

A 64-year-old man who underwent bilateral orthotopic lung transplant for emphysema related to α1-antitrypsin deficiency 8 months ago presented to the clinic for assessment of bilateral pulmonary nodules identified on routine postlung transplant surveillance without any symptomatic concerns. The donor was positive for cytomegalovirus and positive for Epstein-Barr virus, and the recipient was negative for cytomegalovirus and positive for Epstein-Barr virus. He denied any fever, chills, cough, chest pain, dyspnea, weight loss, or night sweats. The patient lived in South Florida with no recent travel history outside the United States or infectious contacts. His posttransplant course was complicated with antibody-mediated rejection at 1.5 months after lung transplant.

How It Works, Simply

This pulmonology research focuses on antibodies · Immune response. Researchers evaluated it using a standard-of-care clinical practice · Clinical case insight at the clinical practice stage of medical research.

Optimizing Sepsis Time Zero Definitions Through Associations between Antibiotic Timing and Mortality

Risk of death associations with antibiotics beyond 1 hour were most evident when sepsis time zero was defined by hypotension or lactate ≥4.0mmol/L, and with antibiotics beyond 3 hours when defined by acute respiratory failure. These findings could inform refinements to sepsis time zero definitions to better guide antibiotic urgency and performance measurement.
