RESUMEN
Pericardial effusion is defined as the accumulation of fluid between the visceral and parietal pericardium. The underlying etiology varies as any pathology that causes pericarditis or involves the pericardium can cause effusion. In practice, the majority of pericarditis cases are idiopathic, although these are assumed to be secondary to occult viral infection or inflammatory phenomena. Malignancy, particularly the metastatic spread of noncardiac primary tumors, has been implicated as a differential in the diagnosis of pericardial effusion. Though commonly seen in solid malignancies, effusion has been reported in hematologic malignancies such as myelodysplastic syndrome (MDS), acute leukemia, and lymphoma. Nonetheless, pericardial effusions associated with hematologic conditions are extremely rare with only one case report published describing pericardial effusion secondary to immune thrombocytopenia (ITP). We herein report the first documented case, to our knowledge, of pericardial effusion as an initial clinical manifestation of aplastic anemia in a middle-aged male presenting with pancytopenia.
RESUMEN
Patients with autoimmune disorders, multiple comorbidities, poor performance status, advanced age, and infection with SARS-CoV-2 (COVID-19) each represent unique subgroups of patients with cancer to whom little is known of the effects, benefits, and complications of checkpoint inhibitor (CPI) therapy. Although prospective trials are lacking in these populations, retrospective data and cohort series suggest that these patients can safely receive and benefit from CPI therapy. Here, we review the relevant data available and offer clinical recommendations in managing these complex patients with CPI therapy, where otherwise indicated.
