Our report describes a case of life-threatening interstitial pneumonitis associated with Guillain-Barré syndrome that occurred during the administration of adjuvant trastuzumab. [ncbi.nlm.nih.gov]

This is characterized by acute worsening of dyspnea within 1 month, accompanied by new bilateral pulmonary opacities at imaging without an identifiable cause [ 5, 6 ]. [ajronline.org]

The features included acute respiratory distress with severe inflammatory reaction; ground-glass opacities and/or consolidations in the upper, anterior and central lung fields on XP/CT; peripheral blood lymphopenia; and diffuse alveolar damage confirmed [ncbi.nlm.nih.gov]

However, patients with abnormal renal function and those with previous calcineurin inhibitor treatment display a higher incidence. The relationship between pneumonitis and mTOR inhibitor plasma concentrations is not well defined. [ncbi.nlm.nih.gov]
