Therefore, the NZB/W F1 mouse is a powerful tool to decipher pathogenic mechanisms involved in SS related polyautoimmunity and develop appropriate therapeutic strategies. Immune checkpoints inhibitors (ICIs) are associated with frequent immune-related adverse events (irAEs), but patients with preexisting autoimmune disease (PAD) have been excluded from clinical trials, leaving serious gaps in knowledge. To evaluate the safety and efficacy of ICIs in PAD patients and cancer and explore the impact of different PAD types and baseline receiving immunosuppressive therapy. Systematic searches were performed of PubMed, EMBASE, and the Cochrane library from inception through August 2019 for observational studies reporting safety and efficacy data among ICI-treated patients with cancer and PAD. 619 ICI-treated patients with PAD in 14 publications were finally identified. In the random-effects meta-analysis, pooled incidence of PAD flares, de novo immune-related adverse events (irAEs) or both of any grade was 60% (95%CI=52%-68%). Separately, there were 219 and 206 patients experiencing PAD exacerbation and de novo irAEs of any grade, yielding a pooled incidence of 35% (95%CI=29%ageable without discontinuing therapy. ICI treatment are also effective in PAD patients, but close monitoring and multidisciplinary collaboration should be contemplated, especially for those concomitantly receiving immunosuppressant or having rheumatoid arthritis.Environmental exposure to sodium dehydroacetate (DHA-S) is inevitable as DHA-S is a high-volume preservative widely used in cosmetics, processed foods and personal care products. DHA-S is absorbed rapidly when administered orally or on the skin and generally considered to be safe and well tolerated. However, DHA-S has recently been reported to induce weight loss and allergic co
