Reintroduction of checkpoint inhibitors after irAE is matter of debate, weighing the risk of a relapse of adverse events against the possibility of improving disease control. Pharmacokinetic modelling has changed the paradigm of weight-based dosing to flat dose for checkpoint inhibitors, however, it is currently unknown if this poses underweight ( less then 80 kg) patients to a higher risk of toxicity. Weight-based dosing has been opted as a less dangerous and more economic option, especially for underweight patients. Is dose reduction dosing a strategy to permit checkpoint inhibitors reintroduction after immune-related adverse events?Methods We describe a case of checkpoint inhibitor reintroduction after immunotherapy-related hepatitis, with dose reduction based on weight-based dosing (nivolumab 165 mg Q2w) in a patient with metastatic renal cell cancer.Results After three cycles, he had a relapse of hepatitis leading to prolonged steroid use and opportunistic infections.Conclusion Dose reduction in underweight patients is not the preferred strategy to permit rechallenge after immunotherapy-related hepatitis. Exploration of other secondary prevention strategies is warranted. The COVID-19 pandemic changed the way that healthcare is delivered, with non-urgent care becoming almost entirely virtual. Underserved communities already battling the opioid epidemic had new challenges in accessing medication assisted treatment (MAT). The investigators sought to determine if patients were retaining access to their opioid use disorder (OUD) treatment and maintaining sobriety during the pandemic, with the intention of using this information to improve subsequent patient care while the pandemic continues. In the assessment, seventy-five patient Epic EMR (electronic medical record) charts were reviewed to collect information
