OBJECTIVE: To investigate the safety and efficacy of a new proteasome inhibitor Ixazomib followed by autologous hematopoietic stem cell transplantation (AHSCT) in the treatment of POEMS syndrome. METHODS: The clinical manifestations, diagnosis and treatment process and follow-up results of 4 patients with POEMS syndrome who were treated with Ixazomib-based regimen combined with AHSCT in Wuhan No.1 Hospital from February 2018 to July 2020 were analyzed retrospectively. All patients were male, aged from 37-54 years old, with varying degrees of peripheral neuropathy, organ enlargement (liver, spleen or lymph nodes), circulatory overload (peripheral edema and/or pleural effusion), osteosclerosis, endocrine diseases (thyroid, gonads, etc.), skin changes (pigmentation, hemangioma, white nails, etc.), M protein, papilledema and other clinical manifestations and characteristics at the time of initial treatment. Two patients were pathologically diagnosed as hyaline vascular Castleman disease by lymph node biopsy. Three patients underwent lumbar puncture examinations and all showed elevated cerebrospinal fluid protein. All patients received at least 2 cycles of sequential AHSCT after induction chemotherapy based on ixazomib. The follow-up time was 10-28 months, and the median follow-up time was 16 months. RESULTS: All cases survived. The complications were controllable during the treatment. Moreover, the clinical symptoms related to the disease were improved to a certain extent after the treatment. The levels of vascular endothelial growth factor (VEGF) showed a gradual decline. CONCLUSION Ixazomib combined with AHSCT is safe and effective in the treatment of POEMS syndrome.

POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, M-protein, skin changes) also known as Crow-Fukase syndrome or Takatsuki syndrome is a rare and disabling paraneoplastic syndrome that frequently occurs in the fifth or sixth decade of life without a known standard first-line therapy. A 34-year-old Filipino male nurse, who presented with gradually progressive distal lower extremity weakness and sharp shooting pain in bilateral legs accompanied by mild joint effusion on the left knee, hypertrichosis, bilateral conjunctival injection, and gynecomastia underwent extensive workup and was diagnosed with POEMS syndrome. Complete blood count revealed erythrocytosis and thrombocytosis with elevated serum VEGF (vascular endothelial growth factor) and elevated monoclonal serum free lambda light chains. The electrophysiologic studies revealed chronic demyelinating sensorimotor polyneuropathy while bone marrow core biopsy and bone marrow aspirate smear immunohistochemical staining showed it to be positive for lambda and CD138. He had an initial unsuccessful treatment course with melphalan and prednisone. Hence, bortezomib and dexamethasone were given which gave significant improvement in symptoms from the overall neuropathy limitation score of 5 to 1.

OBJECTIVE: To analyze the clinical characteristics of patients with POEMS syndrome and explore its effective treatment strategies. METHODS: The clinical data of 75 patients with POEMS syndrome treated in The First Affiliated Hospital of Zhengzhou University from June 2012 to June 2018 were collected and retrospectively analyzed. The clinical characteristics, treatment regimes and outcomes of the patients were summarized. RESULTS: The median age of 75 diagnosed patients was 50 (30-81) years old and 100% (75/75) of the patients were accompanied with peripheral neuropathy, 77.3% (58/75) with organ enlargement, 82.7% (62/75) with endocrine abnormality, 93.3% (70/75) with monoclonal plasma cell diseases and 64.0% (48/75) with skin changes. Among the 75 patients, 5 cases gave up treatment, while the others showed varying degrees of improvement after treatment. The hematological complete remission (CR CONCLUSION The clinical manifestations of POEMS syndrome are complex and diverse, the clinicians therefore should be vigilant to reduce the misdiagnosis and missed diagnosis. Bortezomib or Lenalidomide can be recommended as the first-line medicines and autologous HSCT should be considered for appropriate patients.

OBJECTIVE: To investigated the clinical and pathological characteristics of related-renal damage in patients with POEMS syndrome. METHODS: Five patients diagnosed as POEMS syndrome in our hospital were selected. Their clinical manifestation, pathological characteristics of kidney and laboratory examination were analyzed retrospectively. Among the 5 patients, three males and two females with a median age of 50 years old. The mean interval before diagnosis was 13.0±7.2 months. RESULTS: All the patients showed neuropathy, endocrinopathy, monoclonal plasma cell-proliferative disorder, skin changes and extravascular volume overload, in which 4 patients showed organomegaly. Proteinuria was found in 5 patients, and microhematuria was found in 4 patients. Moreover, 4 patients showed an elevated blood urea, while 2 patients showed creatinine elevation. 1 patient at chronic kidney disease (CKD)-G1 stage, 2 patients at CKD-G2 stage, and 1 patient at CKD-G3b stage, moreover, 1 patient at CKD-G5 stage. Endothelial injury and mesangial lesion were the main characteristics of renal pathology. 3 patients were pathologically diagnosed as thrombotic microangiopathy kidney damage, while 2 patients as light chain amyloidosis. CONCLUSION POEMS syndrome is a multi-systemic disease with complex clinical manifestations. 5 patients had different degrees of renal insufficiency. Endothelial injury and mesangial lesion are the main features of renal pathology.

POEMS syndrome is a rare paraneoplastic disorder. A 60-year-old female patient was admitted to the Department of Gastroenterology, Xiangya Hospital of Central South University (Changsha, China), complaining of abdominal distension, severe edema of both lower limbs and shortness of breath for more than 1 year. After intensive and careful medical investigations, the patient manifested with polyneuropathy, M-proteinemia, splenomegaly, lymphadenopathy, hypothyroidism, extravascular volume overload, sclerotic bone lesions, elevated VEGF and pulmonary hypertension. According to the latest diagnostic criteria of POEMS syndrome, this patient met two mandatory major criteria, two other major criteria and three minor criteria, the diagnosis was clear after ruling out differential diagnosis. The patient was treated with dexamethasone and lenalidomide, which relieved her clinical symptoms. The pathogenesis of POEMS syndrome is not fully understood; however, increased levels of vascular endothelial growth factor may contribute to most of the clinical manifestations. This patient had been in physical discomfort for more than 14 months, which seriously affected her quality of life. Clinically, the awareness of early diagnosis and treatment of POEMS syndrome should be improved.

POEMS syndrome is a rare paraneoplastic syndrome, which includes polyneuropathy, organomegaly, endocrinopathy, M-protein, and skin changes due to plasma cell (PC) neoplasm. Diagnosis of this disease is challenging because of its rarity and complex clinical manifestations. We attempted to identify the key clinical features and characteristic bone marrow (BM) findings of POEMS syndrome, by reviewing the medical records and BM analyses of 24 Korean patients. Frequent clinical manifestations included polyneuropathy (100%), monoclonal gammopathy (100%), organomegaly (92%), extravascular volume overload (79%), and endocrinopathy (63%). The BM analyses revealed mild PC hyperplasia (median PCs: 5.5%) and frequent megakaryocytic hyperplasia (88%), megakaryocyte clusters (88%), and hyperlobation (100%). Flow cytometry of BM aspirates using CD138/CD38/CD45/CD19/CD56 showed normal (67%, 4/6) or neoplastic PC immunophenotypes (33%, 2/6). A diagnosis of POEMS syndrome must be considered when a patient suspected of having PC dyscrasia shows the above clinical presentation and BM findings.

POEMS syndrome is a rare multiple organ involvement of the parasympathetic syndrome associated with abnormal plasma cells, mostly with high-dose chemotherapy and stem cell transplantation for the treatment. Recently, more treatment attempts to treat POEMS syndrome have been utilized so as to improve the efficacy and safety for the patients with POEMS syndrome, such as immunomodulator, alkylating agent, cytokine-induced killer cells and so on. Lenalidomide has a significant effect on relapse/refractory POEMS syndrome and patients with endocrinopathy. Cytokine-induced killer cells are also a safe and effective regimen for the treatment of POEMS syndrome. This review described the efficacy and safety of immunomodulatos, alkylators, cytokine-induced killer cells, ASCT, proteasome inhibitors and monoclonal antibodies for POEMS syndrome, and the newest clinical research and progress of POEMS syndrome ware summarized briefly.

Ischemic stroke caused by the cerebral vasculopathy is a rare complication of polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes (POEMS) syndrome. We present a case of recurrent ischemic strokes caused by cerebral vasculopathy in a patient with POEMS syndrome. A 34-year-old man presented with gait disturbance and dizziness. Brain magnetic resonance imaging demonstrated acute ischemic stroke in the middle cerebral artery-anterior cerebral artery (MCA-ACA) border zones of bilateral hemispheres. Repeated angiographic studies showed progressive worsening of the left distal internal carotid artery, ACA, and MCA stenoses, along with sustained steno-occlusion of right MCA.
