Cerebral venous thrombosis is an uncommon condition in the group of cerebrovascular diseases, usually affecting young individuals. Various risk factors are reported, including thrombophilia, connective tissue diseases, cancer, drugs and head trauma. It can manifest clinically by headache, focal deficits, visual disturbances and seizures, according to the site vascular involved. There are few cases reported in literature about the association of cerebral venous thrombosis with systemic lupus erythematosus. A case of a 34 year-old femalepatient is reported whose initial sign of cerebral venous thrombosis, confirmed by computed tomography and magnetic resonance angiography of the brain, occurred with generalized tonic-clonic seizures. Patient underwent extensive workup, filling the classification criteria for SLE, according to the Guidelines of the American College of Rheumatology, 1997. Patient received therapeutic anticoagulantion and immunosuppressive therapy, being referred to outpatient treatment with the Rheumatology clinic, without recurrence of seizures.
BACKGROUNDRheumatoid arthritis is an autoimmune, chronic and systemic disease with no defined etiology, that primarily affects synovial joints. Lung and pleura are also common sites of extraarticular involvement. Manifestation of interstitial lung disease on RA-onset is a major concern due to its potential seriousness and therapeutic challenge.
CASE REPORTA 51-year-old female, started in August 2020 with dyspnea (mMRC class IV), and sought care in an emergency room. The diagnostic suspicion was SARS-CoV-2 virus infection . Despite having a negative molecular test, a chest tomography was performed and showed multiple ground-glass opacifications. The patient remained hospitalized for a few days and after being discharged from hospital, she maintained severe dyspnea and started with intense myalgia and weakness in the shoulder girdle, being referred by the internal medicine team for rheumatologic evaluation. In the first evaluation, the diagnostic hypothesis of polymyalgia rheumatica was raised, with high-dose prednisone being prescribed and initial diagnostic work up. The patient returned with lab test results that showed positive rheumatoid factor and ACPA (116.2 and 5.9, respectively), in addition to having developed arthritis in some proximal interphalangeal joints, then was established the diagnose of rheumat id arthritis with interstitial lung disease. Treatment with methotrexate was started; however, after 2 months the patient had worsened lung function. A comprehensive review of the literature was carried out and it was decided to start treatment with rituximab, with good therapeutic response.
CONCLUSIONThe best treatment for interstitial lung disease secondary to rheumatoid arthritis is yet to be established. Drug pneumotoxicity raises concern, but current evidence suggests a protector factor in RA patients submitted to methotrexate treatment. Some studies show that the use of glucocorticoids and other biologic or synthetic DMARDs can be beneficial, especially in young patients with usual interstitial pneumonia and symptomatic patients. In an article published in 2020 in Rheumatology, it was concluded that patients with interstitial lung disease who were treated with rituximab apparently had lower mortality rates compared to patients treated with anti-TNF, although the difference did not reach statistical significance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
