    Abstract:
    Polyneuropathy, organomegaly, endocrinopathy, monoclonal plasma cell disorder, and skin changes (POEMS) syndrome is associated with increased risk for ischemic stroke (IS). Because POEMS syndrome is rare, little is known regarding the underlying mechanism and prognosis for IS in patients in whom it occurs. The medical records of patients with POEMS syndrome were screened between January 2018 and January 2000 at Peking Union Medical College Hospital to identify those with IS. The baseline characteristics, IS features, and patient outcomes were analyzed. Forty-one (8.0%) of 510 POEMS patients were documented to have IS. Patients with IS were older, had a higher percentage of Overall Neuropathy Limitation Scale score >4, and had a higher level of fibrinogen compared with those who did not have IS. Ninety-three percent of IS events occurred before or within 3 months after a diagnosis of POEMS. Of 41 occurrences of IS, 29 (46.3%) were multifocal. Recurrent IS was observed in 13 (31.7%) of 41 patients, but not in patients with successful anti-plasma cell therapy. The 3-year overall survival rate in patients with IS was 71.0% and for those without IS, it was 88.5% (P = .002). We showed that 8.0% of POEMS patients had IS, and most IS events occurred in POEMS patients not being treated effectively. Having IS was a predictor of unfavorable prognosis. Early diagnosis, immediate initiation of treatment for POEMS, and control of POEMS syndrome is key to reducing the occurrence of IS, improving survival, and preventing recurrence of IS.
