In patients with POEMS syndrome, which often accompanies plasma cell dyscrasia, the roles of interleukin-6 (IL-6) and other acute phase cytokines are unknown. Serum IL-6, interleukin-1 beta (IL-1 beta) and tumor necrosis factor-alpha (TNF-alpha) were measured by the enzyme-linked immunosorbent assay technique in 16 patients with POEMS syndrome and in patients with other neurological diseases (OND) as control. Serum IL-6 was more frequently detected and higher in active POEMS than in stable POEMS or in OND patients. No sample was positive for IL-1 beta. TNF-alpha was positive in 3 out of 7 active POEMS patients, but its significance was not definite. Serum IL-6 levels in POEMS patients reflected the disease activity but not the severity of accompanying plasma cell dyscrasia.

Polyneuropathy, Organomegaly, Endocrinopathy, Monoclonal Gammopathy, and Skin Changes (POEMS) syndrome is a rare paraneoplastic disorder caused by plasma cell proliferation and overproduction of cytokines, particularly vascular endothelial growth factor (VEGF). This complex syndrome affects multiple organ systems and presents with a broad range of clinical and laboratory manifestations, which can complicate both diagnosis and management. Not all components of the acronym are observed in every patient, highlighting the clinical heterogeneity of the condition.

POEMS syndrome is a multisystemic disease associated with monoclonal plasma cell disorders. Although the presence of bone lesions is included in the diagnostic criteria, their precise manifestations remain unknown. Here, we retrospectively analyzed the bone lesions in patients with POEMS syndrome and evaluated their clinical features.

Objective: This study evaluates the utility of word embeddings, generated by large language models (LLMs), for medical diagnosis by comparing the semantic proximity of symptoms to their eponymic disease embedding ("eponymic condition") and the mean of all symptom embeddings associated with a disease ("ensemble mean").
Materials And Methods: Symptom data for 5 diagnostically challenging pediatric diseases-CHARGE syndrome, Cowden disease, POEMS syndrome, Rheumatic fever, and Tuberous sclerosis-were collected from PubMed. Using the Ada-002 embedding model, disease names and symptoms were translated into vector representations in a high-dimensional space.

POEMS syndrome is a complex and rare hematological disease involving multiple physiological systems. According to the currently accepted diagnostic criteria for POEMS syndrome, polyneuropathy is one of the primary mandatory criteria. A patient presented with M protein, Castleman disease (CD), elevated vascular endothelial growth factor (VEGF), extravascular volume overload, and endocrinopathy.

Background: POEMS syndrome with polyneuropathy, organomegaly, endocrinopathy, M protein, and skin changes is an uncommon plasma cell paraneoplastic syndrome involving multiple system. It is relatively rare in clinical practice, and renal involvement is a usual yet easily overlooked symptom.
Case Presentation: We successfully treated a patient with M protein-negative POEMS syndrome with membranoproliferative glomerulonephritis (MPGN) findings and thrombotic microangiopathic changes by comparing the level of Vascular endothelial growth factor (VEGF) in the serum and the changes in polyserositis before and after the patient's treatment.
