We measured serum interleukin-6 (IL-6) levels in 14 patients with Crow-Fukase syndrome. Five out of 14 patients with Crow-Fukase syndrome showed high serum IL-6 levels above 10 pg/ml, which was statistically significant in comparison with control subjects with other neurological diseases. Serial studies of serum IL-6 levels in two patients revealed the increase before the exacerbation of clinical symptoms of edema, and pleural or cardiac effusion, and the fall after the treatment by high dose pulsed methylprednisolone. We suggest that serum IL-6 level appears to be a useful marker to predict its exacerbation. Also we performed immunohistochemical study on cutaneous angioma from three Crow-Fukase syndrome patients using anti-IL-6 antibody. The cytoplasm of endothelial cells of cutaneous angioma from two patients was positively stained, which might imply the abnormality of endothelial cells in Crow-Fukase syndrome.

A 58-year-old man developed polyneuropathy, organomegaly, gynecomastia, skin pigmentation, and multiple myeloma (IgG-lambda type). Although transient clinical improvement was obtained with prednisolone and cyclophosphamide, his general condition deteriorated progressively, and he died 3 years after onset. Lymph nodes showed angiofollicular hyperplasia, and the sural nerve revealed segmental demyelination. At autopsy, the glomeruli were enlarged and showed mild mesangial cell proliferation with segmental mesangiolysis and proliferation of endothelial cells forming abnormal vessels. The massive volume of ascites contained a high level of interleukin-6 (IL-6). IL-6, a multifunctional cytokine, may be the pathogenic factor which induces the various clinical symptoms and pathological features of Crow-Fukase (POEMS) syndrome.

POEMS syndrome is a rare multisystem affliction known for its signs, from which it also takes its acronym name "peripheral neuropathy, organomegaly, endocrinopathy, monoclonal (M) protein, and skin lesions." Our study chronicles the course of this syndrome in a young woman with Castleman's disease (angiofollicular lymph node hyperplasia). Cerebrospinal fluid (CSF) and serum interleukin-6 (IL-6) levels were abnormally elevated at various times during a 9-month period. The authors conclude that the plasma cell dyscrasia associated with the POEMS syndrome of this patient was Castleman's disease. Elevation of serum IL-6 levels might contribute to the pathogenesis of the POEMS syndrome.

We experienced a 47-year-old Japanese female with polyneuropathy, edema, hypertrichosis, hyperpigmentation, and white nail, which were diagnostic as having Crow-Fukase syndrome. Laboratory and radiological evaluation showed neither plasma cell dyscrasia nor monoclonal gammopathy. Increased factor VIII activity and thrombocytosis, which suggested thrombotic tendency, were observed at the exacerbation of clinical symptoms. In her third exacerbation, she presented marked cyanosis in her right foot, and angiography confirmed narrowing of arteries at the ankle. Increased serum interleukin-6 was also observed, and the production of interleukin-6 by endothelial cells of cutaneous angioma was shown. Possible role of interleukin-6 in Crow-Fukase syndrome was discussed.

We report the case of a 33-year-old Japanese male who presented with thrombocytosis, lower limb edema, severe polyneuropathy with elevated cerebrospinal fluid (CSF) protein level and serum IgA lambda monoclonal component, fulfilling the manifestations of Crow-Fukase syndrome. A high level of soluble interleukin-6 receptor in the CSF was also found, which fluctuated in parallel with the clinical course. Initial treatment with double-filtration plasmapheresis (DFPP) reduced the serum IgA paraprotein level with improvement of the sensory component of the polyneuropathy and decrease of soluble interleukin-6 receptor in the CSF. The remaining clinical features waned off after steroid treatment. The possible role of interleukin-6 in the pathogenesis of the Crow-Fukase syndrome and the utility of DFPP treatment are discussed.

We report six patients affected by POEMS syndrome (Polyneuropathy, Organomegaly, Endocrinopathy, Monoclonal gammopathy, and Skin changes), a peculiar multiorgan disease frequently associated with osteosclerotic myeloma or other plasma cell disorders. Sensorimotor polyneuropathy was associated with multisystem involvement in all of the patients, with osteosclerotic myeloma in 2 cases, monoclonal gammopathy of undetermined significance in 2 cases and Castleman's disease in the final two. In all of the patients, sural nerve biopsy findings were consistent with a mixed, axonal and demyelinating neuropathy. Increased levels of Interleukin-6 were found in two cases, but the pathogenesis of the disease is far from established.

A young Italian woman with a POEMS syndrome is described. The patient had a plasma cell dyscrasia without clinical or laboratory evidence of multiple myeloma. The phenotypic analysis of bone marrow cells and peripheral blood lymphocytes revealed a normal pattern. The immunological study of CSF showed high levels of interleukin-6, whereas this cytokine was not detectable in the serum. Electrophysiological studies and sural nerve biopsy showed a mixed, demyelinating-axonal sensorimotor neuropathy with marked loss of large myelinated fibres. Long-term treatment with prednisone gave some clinical improvement.

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.

We describe a 60-year-old woman who developed mixed connective tissue disease (MCTD) associated with multicentric Castleman's disease (MCD) and Crow-Fukase syndrome (CFS). She showed HLA DR-4 antigen and an abnormal X chromosome (47,XXX). The serum interleukin-6 (IL-6) level was markedly increased and IL-6 mRNA was detected in enlarged lymph node cells. After prednisolone was administered, her IL-6 level decreased and the symptoms of MCTD, MCD, and CFS all improved. Thus, IL-6 may be involved in the modification of the pathologic condition in this patient.

The POEMS (polyneuropathy, organomegaly, endocrinopathy, monoclonal gammapathy, and skin changes) syndrome is a rare variant of plasma cell dyscrasia with multisystemic manifestations. We present 4 cases with arterial symptoms typical of acute arterial obliteration (AAO) and review 9 similar cases in the literature. The clinical course of AAO was unusual and particularly severe when affecting the lower limbs; recurrent events required amputations. As demonstrated by angiographic and histologic studies, thrombotic and atheromatous lesions were the main pathologic features of AAO. Atherosclerotic risk factors were absent or moderate in 3 of our cases, and no cause of thrombosis other than the POEMS syndrome was found. A high production of cytokines was found in all cases, with elevated serum levels of interleukin-1 beta (9/9 samples), interleukin-6 (7/9 samples), and tumor necrosis factor-alpha (6/9 samples). We suggest that arterial manifestations should be added to the spectrum of manifestations of the POEMS syndrome. Cytokines may mediate the POEMS syndrome-associated AAO, as previously proposed for the other systemic manifestations of this disorder.
