A case of biopsy-confirmed chronic leptomeningitis complicating rheumatoid arthritis in a 53-year old female is reported. Her symptoms included weight loss, severe depression, and pyrexia. Magnetic resonance imaging was useful in diagnosis. Intravenous methylprednisolone was prescribed (1 g/day for 3 days), followed by prednisolone (initial dose of 30 mg daily), and this treatment was effective. Her IgG-index, serum levels of soluble interleukin-2 receptor and ferritin, and cerebrospinal level of interleukin-6 paralleled her clinical course.
Objective Rheumatoid arthritis (RA) may be complicated by different infections, but risk factors for these are not fully elucidated. Here, we assessed the incidence of and risk factors for infections requiring hospitalization (IRH) including pneumocystis pneumonia (PCP) in patients with RA. Methods We retrospectively surveyed all RA patients treated at our hospital from 2009 to 2013, for whom data were available on demographic features, medications, comorbidities, and severity of RA. Multivariate logistic regression analysis was applied to calculate adjusted odds ratios (ORs) for factors associated with the occurrence of IRH. ResultsIn a total of 9210 patient-years (2688 patients), there were 373 IRH (3.7/100 patient-years). Respiratory tract infections were most frequent (n = 154, and additionally 16 PCP), followed by urinary tract infections (n = 50). Significant factors for PCP included higher age (≥70 years; OR 3.5), male sex (6.6), underlying lung disease (3.0), use of corticosteroids (4.8), and use of biologics (5.4). Use of methotrexate (5.7) was positively associated with PCP but negatively with total infections (0.7). Additionally, functional disorders and higher RA disease activity were also related to total infections. Conclusions Risk factors for infection should be taken into account when deciding treatment for the individual RA patient.
We describe a 54-year-old female patient with rheumatoid arthritis (RA) and Sjögren's syndrome (SS) who presented with right chest pain and a large mass visible in the upper right field of a chest X-ray. Computed tomography (CT) showed multiple tumours in both lungs, the liver, and the spleen. The right lung tumour was 8 cm in diameter with a cavity. Biopsy of the lung and liver revealed lymphomatoid granulomatosis (LG) and diffuse large B-cell lymphoma (DLBCL). These lesions spontaneously regressed after withdrawal of methotrexate without any therapy for the lymphoma. This is the first report of self-limiting LG in a patient, complicated with methotrexate-treated RA.

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.
