Rheumatoid arthritis (RA) is a chronic, systemic inflammatory disease affecting a significant portion of the global population. Despite advancements in pharmacological treatments, the management of RA remains complex, particularly in regard to comorbidities such as cardiovascular disease and osteoporosis. Physiotherapy (PT) and occupational therapy (OT) are non-pharmacological approaches that play a critical role in the management of RA.

Coronavirus disease 2019 (COVID-19) vaccination is essential for patients with autoimmune inflammatory rheumatic diseases (AIIRD) to reduce the risk of morbidity and mortality associated with serious COVID-19 infection. With endemicity, waning of vaccine- and infection-acquired immunity, and development of SARS-CoV-2 variants, the need for additional doses of vaccines against serious illness in high-risk immunocompromised persons remains imperative. This review examines how immunomodulatory therapies affect vaccine-induced immune response in patients with AIIRD.

We report 2 patients who first developed cutaneous manifestations, followed by autoimmune phenomena, infections, and hypogammaglobulinemia. They were initially diagnosed with common variable immunodeficiency; however, the diagnosis was revised to cytotoxic T-lymphocyte antigen 4 haploinsufficiency after genetic and functional testing.

Since the introduction of coronavirus disease 2019 (COVID-19) messenger ribonucleic acid (mRNA) vaccines, there have been multiple reports of post-vaccination myocarditis (mainly affecting young healthy males). We report on four patients with active autoimmune rheumatic diseases (ARDs) and probable or confirmed myocarditis following COVID-19 mRNA vaccination managed at a tertiary hospital in Singapore; we reviewed the literature on post-COVID-19 mRNA vaccination-related myocarditis and ARD flares. Three patients had existing ARD flares (two had systemic lupus erythematosus (SLE), one had eosinophilic granulomatosis polyangiitis (EGPA)), and one had new-onset EGPA.

Good syndrome (GS) is a primary immunodeficiency (PID) that presents in middle aged to older adults with features of thymoma, hypogammaglobulinemia, CD4 T lymphopenia, inverted CD4/CD8+ ratio, and impaired T-cell mitogen proliferative responses. We present a patient, a 62-year-old female, who first presented with disease manifestation of acute hepatitis from hepatitis B virus (HBV) reactivation, which was subsequently complicated by recurrent hospitalizations for recurrent pneumonia and concomitant and cytomegalovirus enteritis. She was later found to have thymoma and hypogammaglobulinemia and was diagnosed with GS.

Rhombencephalitis (RE) refers to inflammatory diseases involving the brainstem and cerebellum. Although RE is a rare entity, it is associated with high morbidity and mortality. The management of such patients is often challenging in terms of identifying the etiology and defining prognosis.
