We present two cases of patients who consulted due to unusual symptoms and whose loss of strength led to an approach due to multisystem involvement that concluded with the diagnosis of this disease(AU)

Ixazomib-Based Regimen Followed by Autologous Hematopoietic Stem Cell Transplantation in the Treatment of POEMS Syndrome / 中国实验血液学杂志

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.

Síndrome POEMS: desafios no diagnóstico de um caso atípico / POEMS syndrome: challenges in the diagnosis of an atypical case

Introdução: Síndrome POEMS trata de um raro evento paraneoplásico, sem relato atual na literatura sobre sua real prevalência. A maior parte dos casos ocorre em homens de meia idade; Relato do Caso: Relatamos o caso de um paciente masculino, 65 anos, admitido com queixa edema e parestesia em pernas que evoluiu para plegia, associada a hiporexia e fadiga. Investigação ambulatorial inicial evidenciou polirradiculoneuropatia inflamatória desmielinizante crônica (PIDC) de etiologia indefinida. Excluídos secundarismos para polirradiculoneuropatia inflamatória desmielinizante crônica, o paciente foi a seguir diagnosticado com hipotireoidismo primário, hipogonadismo severo, lesões hipercrômicas em pele, ascite, derrame pleural e trombocitose, além de gamopatia monoclonal IgA Lambda por imunofixação sérica. Sorologias para HIV, Sífilis e Hepatites todas negativas. Excluída a possibilidade de Mieloma Múltiplo e outras gamopatias, foi aventada a hipótese de Síndrome POEMS, sendo realizada dosagem de Fator de Crescimento Endotelial Vascular (VEGF) plasmática (425 pg/mL; VR = <96.2). O paciente passou então a preencher os critérios obrigatórios para diagnóstico, além de um maior (VEGF elevada) e vários outros menores. Trata-se de um caso atípico na medida em que, lesões ósseas, presentes em até 97% dos casos, não foram evidenciadas no paciente em questão, tornando desafiador o diagnóstico e sendo então necessário recorrer à dosagem de VEGF. O diagnóstico de síndromes raras, embora desafiante, traz ao clínico um olhar mais amplo do paciente na medida em que incrementa o raciocínio clínico. Difundir e explorar esse universo é cada vez mais necessário

Introduction: POEMS syndrome is a rare paraneoplastic event, with no current report in the literature about its real prevalence. Most cases occur in middle-aged men; Case Report: We report the case of a male patient, 65 years old, admitted with complaints of edema and paresthesia in the legs that progressed to plegia, associated with hyporexia and fatigue. Initial outpatient investigation revealed Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP) of undefined etiology. Excluding secondaries for chronic inflammatory demyelinating polyradiculoneuropathy, the patient was subsequently diagnosed with primary hypothyroidism, severe hypogonadism, hyperchromic skin lesions, ascites, pleural effusion and thrombocytosis, in addition to monoclonal IgA Lambda gammopathy by serum immunofixation. All serologies for HIV, Hepatitis and syphilis were negative. Excluding the possibility of Multiple Myeloma and other gammopathies, the hypothesis of POEMS Syndrome was raised, and plasma Vascular Endotelial Growth Factor (VEGF) measurement was performed (425 pg/mL; RV = <96.2). The patient then started to fulfill the mandatory criteria for diagnosis, in addition to a major (elevated VEGF) and several other minors. This is an atypical case in that bone lesions, present in up to 97% of the cases, were not evidenced in the patient in question, making the diagnosis challenging and therefore requiring the use of VEGF dosage. The diagnosis of rare syndromes, although challenging, brings the clinician a broader view of the patient as it increases clinical reasoning. Spreading and exploring this universe is increasingly necessary

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.

POEMS syndrome presenting with abdominal distension, lower limb edema and shortness of breath: A case report and literature review / 中南大学学报(医学版)

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: Bone Marrow, Laboratory, and Clinical Findings in 24 Korean Patients

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.

Síndrome POEMS: um diagnóstico desafiador / POEMS Syndrome: a challenging diagnosis

A síndrome POEMS é um distúrbio multissistêmico. Sua patogênese não está totalmente estabelecida, mas sabe-se que tem relação com fator de crescimento vascular endotelial, interleucinas e fator de necrose tumoral alfa. A idade média de incidência é 50 anos, com maior prevalência em homens. Neuropatia periférica e gamopatia monoclonal estão presentes em todos os pacientes e são consideradas critérios maiores; quando associadas a pelo menos um critério menor, estabelecem diagnóstico da síndrome. As opções de tratamento são radioterapia, corticosteroides e quimioterapia, além de transplante autólogo de células-tronco hematopoiéticas. (AU)

POEMS syndrome is a multisystem disorder. Its pathogenesis isn't fully established, but it is known to be related to endothelial vascular growth factor, interleukins, and tumoral necrosis factor alpha (TNF-α). The mean age at incidence is 50 years, with a higher prevalence in men. Peripheral neuropathy and monoclonal gammopathy are present in all patients, and are considered major criteria; when associated with at least one minor criterium, they establish the diagnosis of the syndrome. Treatment options are radiotherapy, corticosteroids, chemotherapy, as well as autologous hematopoietic stem cell transplantation. (AU)

Síndrome de POEMS, el desafío diagnóstico de un caso infrecuente / POEMS syndrome, the diagnostic challenge of an infrequent case / Síndrome de POEMS, o desafio diagnóstico de um caso infrequente

Se reporta el caso de un hombre de 45 años con síntomas y signos consistentes con el Sindrome de POEMS (del inglés: polineuropatía, organomegalia, endocrinopatía, gammapatía monoclonal y cambios dérmicos), un raro desorden paraneoplásico. El mismo contaba con antecedentes de tabaquismo, hipotiroidismo y últimamente había perdido 20 kg de peso. Se destaca que una historia clínica y revisión detallada seguida de estudios de laboratorio, radiología y biopsia de médula ósea, entre otros, son herramientas necesarias para reconocer los componentes de este síndrome y no demorar el diagnóstico. El paciente presentó 2 criterios obligatorios (gammapatía monoclonal y neuropatia periférica sensitivo-motora), un criterio mayor (lesión ósea) y varios criterios menores (desórdenes endocrinos, manifestaciones cutáneas, organomegalia). Actualmente se encuentra bajo supervisión hematológica y continúa su seguimiento neurológico, lo que muestra una buena respuesta a la terapia específica. Las enfermedades raras como este síndrome resultan un desafío diagnóstico para los profesionales de la salud.

The case of a 45 - year- old- man whose symptoms and signs were consistent with POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy and skin changes), a rare paraneoplastic disorder, has been reported. He had a previous history of smoking, hypothyroidism and a 20 kg weight loss. It was emphasized that a detailed clinical history and examination followed by laboratory and radiological studies and bone marrow biopsy, among others tests, were necessary in order to recognise the components of this syndrome and not to delay the time of diagnosis. This patient had two mandatory criteria (monoclonal gammopathy and sensorimotor polyneuropathy), one major criterion (bone lesion) and several minor criteria (endocrine disorders, cutaneous manifestations, organomegaly). He is currently under the supervision of the doctors of the hematology department and continues neurological follow-up, having a good response to the specific therapy. Rare diseases like this syndrome are a diagnostic challenge for health professionals.

Ischemic Stroke with Cerebral Vasculopathy in POEMS Syndrome

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.

Progress in Treatment of POEMS Syndrome--Review / 中国实验血液学杂志

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.

Compromiso renal en síndrome de Poems: caso clínico / Chronic kidney disease associated with Poems syndrome: report of one case

POEMS syndrome is characterized by Polyneuropathy, Organomegaly, Endocrinopathy, Monoclonal protein and Skin changes. We report a woman with the syndrome, who had peripheral polyneuropathy, osteosclerotic myeloma, monoclonal IgA elevation, hypothyroidism, hypogonadotrophic hypogonadism, hyperprolactinemia, adrenal insufficiency, hepatosplenomegaly, lymphadenopathy, thyroid and parotid enlargement, Castleman’s disease, papilledema, stiff and hyperpigmented skin, white nails, clubbing, ascites and chronic diarrhea. She had also a nephropathy characterized by microscopic hematuria, proteinuria, renal insufficiency and a unilateral kidney retraction. She was treated with melphalan and prednisone, achieving remission of the disease and nephropathy. She survived twelve years and died due to a myocardial infarction 20 years after POEMS diagnosis.

A Rare Case of Polyneuropathy and Monoclonalgammopathy with Recurrent Acute Kidney Injury

POEMS syndrome is a rare paraneoplastic syndrome and there are few reports of polyneuropathy and monoclonal gammopathy associated with kidney dysfunction. Here, we report a case of POEMS syndrome with recurrent acute kidney injury (AKI). A 52-year-old man presented with bilateral aggravating paresthesia and latermotor weakness of the lower extremities accompanied by repeated elevation of serum creatinine. The patient was finally diagnosed with POEMS syndrome on the basis of fulfilling the two mandatory major criteria (polyneuropathy and monoclonal gammopathy), one other major criterion (sclerotic bone lesion), and several minor criteria. A renal biopsy was performed to clarify the cause of AKI and showed membranoproliferative glomerulonephritis-like lesions with mesangiolysis and endothelial cell injury. This case illustrates that renal manifestations, not included in the diagnostic criteria for POEMS, can be apparent before various other systemic symptoms.
