A Case of Capillary Leak Syndrome and Intestinal Ischemia Caused by Rheumatoid Vasculitis

Atlantoaxial Subluxation as the Initial Presentation of Rheumatoid Arthritis: A Case Report

Rheumatoid arthritis (RA) is known for its diverse manifestations, although atlantoaxial subluxation is a rare complication. This case report sheds light on the complexity of RA diagnosis, especially in the elderly, and emphasizes the significance of primary care in identifying atypical presentations. A 68-year-old male with a history of chronic obstructive pulmonary disease, hypertension, prior traumatic neck spinal injury, and lumbosacral stenosis presented to a rural community hospital with neck pain, bilateral numbness, and arm weakness. Initially diagnosed with degenerative cervical spondylosis, his condition later progressed to include swollen, painful wrists and metacarpophalangeal joints. Diagnostic tests revealed elevated rheumatoid factor and C-reactive protein, and hand X-ray showed bone erosions. An MRI confirmed an atlantoaxial subluxation. He was diagnosed with RA based on the American College of Rheumatology/European League Against Rheumatism 2010 criteria with a score of 7. The patient underwent cervical fusion surgery and rehabilitation, leading to significant functional improvement. This case underscores the importance of a comprehensive diagnostic approach in primary care for elderly patients presenting with non-specific symptoms. It highlights the need for heightened awareness among general practitioners of atypical RA manifestations, such as atlantoaxial subluxation. The case advocates for continued research into early detection and management strategies for such rare presentations to enhance patient outcomes in RA.

Rheumatoid Vasculitis Complicated With Acute Inflammatory Demyelinating Polyneuropathy in an Older Female: A Case Report

Rheumatoid vasculitis (RV) causes various complications in the heart, lungs, kidneys, and nerves that require intensive treatment. Rapid RV-related peripheral nerve involvement progression is critical and requires prompt treatment. We report the case of a 73-year-old female with RV, with a chief complaint of difficulty walking without any infectious symptoms for several months. We diagnosed Guillain-Barré syndrome (GBS) accompanied by RV and treated the patient with intravenous immunoglobulin and cyclophosphamide. Previous impairments of activities of daily living (ADLs) were resolved. Diagnosing the neurological manifestations of RV and GBS in older patients with an active RV is challenging because of the various patterns of the progression. For effective management, considering both diseases and implementing immunosuppressive and modulatory treatments is critical to stop the progression of neurological symptoms and prevent the deterioration of ADLs.

Treating Exudative Pleurisy Accompanied by Felty Syndrome in an Older Patient With Advanced Rheumatoid Arthritis

Advanced rheumatoid arthritis (RA) is complicated by extra-articular manifestations such as small- and medium-sized vasculitis, pulmonary fibrosis, and pleurisy. The clinical course of the disease is refractory and critical. Treating advanced RA with multiple extra-articular manifestations is challenging. Here, we report a case of advanced RA in a 75-year-old man with exudative pleurisy and Felty syndrome. Treatment should be initiated promptly while paying attention to the possibility of infection as a differential diagnosis of exudative pleurisy because of the drastic change in the patient's condition due to disease progression. In addition, appropriate treatment is required to differentiate between Felty syndrome and malignant diseases. In older patients with RV complicated by pleurisy and Felty syndrome, starting steroids and immunosuppressive agents is crucial when conducting a thorough examination and considering the rapid progression of symptoms.
