Neutropenia in rheumatoid arthritis (RA) is a problem that often needs to be addressed. Side effects of basic antirheumatic treatment, infections or substrate deficiencies are common causes; however, T‑cell large granular lymphocytic (T-LGL) leukemia, a mature T‑cell neoplasm, can also lead to autoimmune cytopenia. The T‑LGL leukemia can be associated not only with RA but also with other autoimmune diseases or neoplasms.

Felty's syndrome (FS) is a rare and complex condition most commonly seen as a complication of longstanding rheumatoid arthritis (RA), characterized by a triad of RA, splenomegaly, and neutropenia. Diagnosing FS can be challenging due to its diverse clinical presentations and overlap with other hematologic and autoimmune conditions. We report a 47-year-old male with a history of severe anemia, recurrent blood transfusions, and a chronic leg ulcer.

Objective: We analyzed adverse events (AEs) related to adalimumab and etanercept using the Food and Drug Administration Adverse Event Reporting System (FAERS) to detect unexpected AEs. Subsequently, we compared the discrepancy in serious outcomes involving the same injection site reactions (ISRs) between two different medications.
Methods: Four algorithms, including reporting odds ratio (ROR), proportional reporting ratio (PRR), Bayesian confidence propagation neural network (BCPNN), and the multi-item gamma Poisson shrinker (MGPS) were used to identify AE signals.

Felty's syndrome (FS) is an uncommon disorder with a poor prognosis, and most patients die from infections caused by neutropenia. Currently, there is no standardized treatment strategy, and treatment options are based on case reports and clinical experience. To date, no cases of FS complicated by coronavirus disease-2019 (COVID-19) have been reported.
