Angiogenin is a member of the ribonuclease superfamily that is associated with the angiogenic process. Angiogenesis is regarded as an important step to support primary and metastatic tumor growth. In cutaneous T cell lymphoma (CTCL), angiogenesis in lesional skin is increased, suggesting that interaction between tumor cells and their microvasculature are likely to occur during progression of CTCL. Patients with hematological malignancies show increased serum angiogenin levels, which are related with poor overall survival. To investigate possible roles of angiogenin in development of CTCL, we measured serum angiogenin levels in 36 patients with CTCL and 21 healthy controls by enzyme-linked immunosorbent assay. We also investigated angiogenin mRNA and protein expression in lesional skin of CTCL by quantitative RT-PCR and immunohistochemistry. Serum angiogenin levels in patients with CTCL were significantly higher than those in healthy controls. When classified with types of skin lesions, serum angiogenin levels were elevated only in erythrodermic CTCL patients. Angiogenin mRNA expression levels in lesional skin were significantly elevated in erythrodermic CTCL compared to normal skin. Immunohistochemical study revealed that angiogenin was expressed by keratinocytes, endothelial cells, and infiltrating lymphocytes in CTCL. Our results suggest that enhanced angiogenin expression may be related with a poor prognosis of erythrodermic CTCL. As angiogenin acts as an inhibitor of polymorphonuclear leukocyte degranulation, angiogenin may also be linked to impaired host defense in erythrodermic CTCL. 相似文献

The purpose of this phase I and II study was to evaluate the safety, pharmacokinetics, pharmacodynamics, and efficacy of bortezomib in Japanese patients with relapsed or refractory multiple myeloma. This was a dose-escalation study designed to determine the recommended dose for Japanese patients (phase I) and to investigate the antitumor activity and safety (phase II) of bortezomib administered on days 1, 4, 8, and 11 every 21 days. Thirty-four patients were enrolled. A dose-limiting toxicity was febrile neutropenia, which occurred in one of six patients in the highest-dose cohort in phase I and led to the selection of 1.3 mg/m2 as the recommended dose. Adverse events ≥ grade 3 were rare except for hematological toxicities, although there was one fatal case of interstitial lung disease. The overall response rate was 30% (95% confidence interval, 16–49%). Pharmacokinetic evaluation showed a biexponential decline, characterized by a rapid distribution followed by a longer elimination, after dose administration, whereas the area under the concentration–time curve increased proportionately with the dose. Bortezomib was effective in Japanese patients with relapsed or refractory multiple myeloma. A favorable tolerability profile was also seen, although the potential for pulmonary toxicity should be monitored closely. The pharmacokinetic and pharmacodynamic profiles of bortezomib in the present study warrant further investigations, including more relevant administration schedules.

Systemic sclerosis (SSc) is a chronic autoimmune inflammatory disease characterized by extensive tissue fibrosis and various vascular complications. A wealth of evidence suggests the substantial contribution of pro‐inflammatory cytokines to the development of SSc, but the role of interleukin (IL)‐18 signaling in this disease still remains elusive. To address this issue, we herein determined serum levels of IL‐18‐binding protein isoform a (IL‐18BPa), a soluble decoy receptor for IL‐18, by enzyme‐linked immunosorbent assay in 57 SSc patients and 20 healthy controls and evaluated their clinical correlation. Serum IL‐18BPa levels were higher in SSc patients than in healthy controls, while comparable between diffuse cutaneous SSc and limited cutaneous SSc patients. Although serum IL‐18BPa levels were not associated with dermal and pulmonary fibrotic parameters in SSc patients, there was a significant positive correlation between serum IL‐18BPa levels and right ventricular systolic pressure estimated by echocardiography. Furthermore, in 24 SSc patients who underwent right heart catheterization, serum IL‐18BPa levels positively correlated with mean pulmonary arterial pressure. As for systemic inflammatory markers, significant positive correlations of circulating IL‐18BPa levels with erythrocyte sedimentation rate and C‐reactive protein were noted. These results suggest that the inhibition of IL‐18 signaling by IL‐18BPa may be involved in the development of pulmonary vascular involvement leading to pulmonary hypertension and modulate the systemic inflammation in SSc. 相似文献

Cutaneous apocrine carcinoma (CAC) is a rare malignancy. It develops predominantly in the regions where apocrine glands are distributed. Some cases of CAC have been reported in the axilla and the inguinal regions, but only a few in the scrotum. We herein report a case of CAC which widely spread over both sides of the whole scrotum with plate‐like hard induration, and such a manifestation has never been reported before. CAC is known to have high rates of local recurrence or metastasis, and the efficacy of radiotherapy or chemotherapy has not been established. As therapeutic options for CAC are limited, it is critical to reach the diagnosis and treat at an early stage. 相似文献
