Introduction Systemic lupus erythematosus (SLE) complicated by multiple myeloma (MM) is a relatively rare clinical presentation, and is easily ignored due to their similar or even identical manifestation, which may lead to misdiagnosis and mistreatment. Case report We report two cases of SLE with MM. Case 1 was a 59‐year‐old male who was diagnosed with SLE 11 years ago. Abnormal kidney function was detected 4 months ago and a bone marrow aspirate revealed MM. He then received three cycles of bortezomib, dexamethasone, and chemotherapy with liposomal doxorubicin, and one cycle of lenalidomide plus dexamethasone. He died of infectious shock. Case 2 was a 58‐year‐old female who was diagnosed with SLE 27 years ago. After the onset of abnormal renal function 4 years ago, the patient was still treated according to SLE disease activity. When renal function rapidly deteriorated, serum and urine immunofixation electrophoresis was positive for IgG γ with free light chains and she was diagnosed with SLE complicated by MM. She did not agree to the treatment for MM as advised and was discharged from the hospital against medical advice. Case 2 died of cardiac failure. Thirteen cases of SLE with MM reported from 2000 to 2022 in PUBMED and Mendeley and our above two cases were reviewed. Among the 15 patients, 13 were females and 2 were males. The median age at the time of SLE with MM diagnosis was 50 years, and the median time to a delayed diagnosis was 7 years. The serum monoclonal immunoglobulin level was elevated and extramedullary manifestations of renal dysfunction were common. Conclusions An elevated monoclonal immunoglobulin level or newly unexplained renal dysfunction occurring in a patient with SLE should prompt monitoring and further screening of MM, rather than treatment as a secondary manifestation of SLE.
Objective: Numerous studies have investigated the expression of forkhead box O3a (FOXO3a) in autoimmune diseases, but the results were inconsistent. This meta-analysis aims to synthetically evaluate the levels of FOXO3a in autoimmune diseases.Methods: PubMed, Web of Science, and China National Knowledge Infrastructure were used to retrieve relevant articles. The pooled standard mean difference with 95% confidence interval was calculated.Results: Totally, 10 studies from 7 publications were included. The levels of FOXO3a were significantly decreased in patients with autoimmune diseases compared with healthy controls (standard mean difference, −1.045; 95% confidence interval, −1.892 to −0.197). When stratified by disease, FOXO3a levels were significantly decreased in rheumatoid arthritis (RA) and inflammatory bowel disease (IBD), but were significantly increased in systemic lupus erythematosus. FOXO3a levels of specific tissues or cells in patients with autoimmune diseases were significantly decreased, but no significant difference was observed in the subgroup of peripheral blood mononuclear cells. In the subgroup analysis combining disease and sample, significant differences of FOXO3a were observed in non-PMBCs of RA and IBD patients.Conclusions: Our study indicated that FOXO3a were significantly decreased in patients with autoimmune diseases. FOXO3a levels was a potential therapeutic target of autoimmune diseases.
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.
