A retrospective analysis of endocrinopathy manifestations in 136 Chinese patients with POEMS syndrome.

OBJECTIVE: POEMS syndrome is a rare multisystemic disease, with a wide spectrum of clinical endocrinopathies. Patients with POEMS syndrome may present with one or more hormone disorders during the disease course, but such phenomenon has usually been underestimated. In this report, we analyzed the prevalence and clinical characteristics of endocrine abnormalities in a large Chinese cohort with POEMS syndrome. METHODS: This retrospective review was performed in patients with a definite diagnosis of POEMS syndrome who were hospitalized in our hospital between January 2000 and January 2020. The clinical data about endocrine abnormalities were extracted from their medical records and analyzed. RESULTS: This study comprised 136 patients (95 male, 41 female) with a median age of 48(40-56) years old. Endocrine abnormalities were frequent (127 cases, 93.38%) in patients with POEMS syndrome. The prevalence of single endocrinopathy and multiple endocrinopathies were 12.60% (16/127 cases) and 87.40% (111/127), respectively. The most frequent endocrinopathy was hypogonadism (98/136, 72.06%), followed by hypothyroidism (83/136, 61.03%), hypocalcemia (50/136, 36.76%), hyperprolactinemia (47/136, 34.56%), abnormal glucose metabolism (41/136, 30.15%) and adrenal insufficiency (41/136, 30.15%). In patients with multiple endocrinopathies, the prevalence of 2, 3, 4, 5, and 6 kinds of endocrine axes involved were 29.92% (38/127), 30.71% (39/127), 17.32% (22/127), 7.09% (9/127) and 2.36% (3/127), respectively. Such hormone disorders cause complex clinical presentations, including overt or subclinical situations. CONCLUSION: Endocrinopathy manifestations in POEMS syndrome are more frequent, and its clinical complicacy should be emphasized in differential diagnosis. For patients with a definite diagnosis of POEMS syndrome, an early and thorough endocrine evaluation should be performed.
