Treatment with propylthiouracil is associated with appearance of antineutrophil cytoplasmic antibodies in some patients with Graves' disease. 总被引:16,自引:0,他引:16

The use of propylthiouracil (PTU) for the treatment of Graves' disease is associated with few adverse effects such as skin eruptions, liver dysfunction, and agranulocytosis. Furthermore, recent studies described the development of antineutrophil cytoplasmic antibody (ANCA)-related glomerulonephritis and vasculitis in patients treated with PTU. Here we investigated whether PTU therapy per se is associated with the appearance of ANCA in patients with Graves' disease. We analyzed 119 serum samples from 117 patients with Graves' disease treated with either PTU (n = 56), or methimazole (MMI) (n = 21), as well as untreated patients (n = 42). Myeloperoxidase (MPO)-ANCA and proteinase 3 (PR3)-ANCA were tested by enzyme-linked immunosorbent assay (ELISA) kits. MPO-ANCA was negative in all patients treated with MMI therapy and untreated patients. However, MPO-ANCA was detected in 21 (37.5%) of 56 patients treated with PTU therapy. Furthermore, two patients who were negative for MPO-ANCA became positive after PTU therapy. The proportion of patients positive for MPO-ANCA increased with the prolongation of PTU therapy, but did not correlate with age, gender, and positive antithyroperoxidase (TPO) antibody. Among 21 MPO-ANCA positive patients, 12 had no symptoms, but 9 patients complained of myalgia, arthralgia, or common cold like symptoms after the appearance of MPO-ANCA. Three patients developed agranulocytosis or granulocytopenia, but none showed abnormal urinary findings. Our results suggest that PTU per se is associated with the production of MPO-ANCA in patients with Graves' disease. 相似文献

Fas/FasL mediated apoptosis of thyrocytes in Graves' disease. 总被引:8,自引:0,他引:8
N Sera A Kawakami T Nakashima H Nakamura M Imaizumi T Koji Y Abe T Usa T Tominaga E Ejima K Ashizawa N Yokoyama N Ishikawa K Ito K Eguchi 《Clinical and experimental immunology》2001,124(2):197-207
We examined in the present study the possible involvement of Fas and its ligand (FasL) in the process of Graves' disease. Immunohistochemical analysis showed that few normal thyrocytes expressed Fas but many thyrocytes in Graves' disease expressed this molecule. The percentage of FasL-positive thyrocytes in Graves' thyroids was, however, less than in normal thyroids. Several apoptotic thyrocytes and infiltrating mononuclear cells (MNCs) were detected scattered throughout Graves' thyroid tissues and abundant proliferating cell nuclear antigen (PCNA)-positive thyrocytes were present. Apoptotic cells, as well as PCNA-positive cells, were scarcely detectable in normal thyroid glands, however. In vitro treatment of thyrocytes by IL-1beta a cytokine found to be expressed in Graves' thyroid glands, increased Fas but reduced FasL expression. IL-1beta-stimulated thyrocytes became sensitive to apoptosis by anti-Fas IgM monoclonal antibody (mAb). Activated T cells, which strongly expressed FasL, showed cytotoxic activity toward IL-1beta-stimulated thyrocytes but not toward unstimulated thyrocytes. This cytotoxic activity involved the Fas/FasL pathway. Importantly, unstimulated thyrocytes could kill activated, but not resting, T cells. IL-1beta-stimulated thyrocytes, with down-regulated FasL expression, could not efficiently kill activated T cells. The cytotoxic activity of unstimulated thyrocytes toward activated T cells was inhibited by anti-FasL mAb. Interestingly, unstimulated thyrocytes induced apoptosis in IL-1beta-stimulated thyrocytes but not in unstimulated thyrocytes. These interactions were also blocked by anti-FasL mAb. Our results suggest that the apoptotic cell death of both thyrocytes and infiltrating MNCs found in Graves' thyroid glands is regulated by IL-1beta through Fas/FasL interactions. 相似文献

To investigate the relationship between thyroid function and carotid intima-media thickness (CIMT) in a relatively large general population with euthyroid status we initially enrolled 1772 Japanese adults (421 men and 1351 women) who participated in a medical screening program for the general population over 40 years old. To evaluate only euthyroid subjects without vascular diseases and/or its major risk factors, 1129 were excluded and 643 participants (175 men and 468 women) were included for further analysis. Simple and multivariate linear regression analyses were performed to evaluate free thyroxine (fT4) and thyroid-stimulating hormone (TSH) levels and other existing parameters, including carotid intima-media thickness. By multivariate linear regression analysis adjusted for age and sex, free thyroxine was significantly correlated with triglycerides (beta=0.07, p=0.015), carotid intima-media thickness (beta=-0.091, p=0.049), and thyroid-stimulating hormone (beta=-0.091, p=0.003). Thyroid-stimulating hormone was significantly correlated with high-density lipoprotein cholesterol (HDL-C) (beta=-0.001, p=0.015), HbA(1c) (beta=0.038, p=0.045), carotid intima-media thickness (beta=0.27, p=0.001), and free thyroxine (beta=-0.15, p=0.003). When adjusted for confounding factors, free thyroxine was significantly correlated only with carotid intima-media thickness (beta=-0.13, p=0.043) and thyroid-stimulating hormone was significantly correlated with HDL-C (beta=-0.001, p<0.001), HbA(1c) (beta=0.04, p=0.021), and carotid intima-media thickness (beta=0.29, p=0.001). We have demonstrated that carotid intima-media thickness is independently associated with thyroid function within the normal reference range, which suggests an increased cardiovascular risk in subjects with low normal thyroid function. 相似文献

We aimed to report the coverage and safety of the influenza A (H1N1) 2009 monovalent vaccination (Panenza; Sanofi Pasteur, Val de Reuil Cedex, France) among health care personnel (HCP) in a university hospital setting in Thailand. The hospital set up a system to vaccinate HCP and did surveillance of the adverse effects (AEs). During a 4-week period, 6,210 (78.7%) HCP were vaccinated. There were 82 reported nonserious AEs among 32 HCP. The most common AE was fatigue/uncomfortable feeling (24%). 相似文献

ObjectiveTo investigate the genetic polymorphism of Plasmodium vivax (P. vivax) PvCSP and PvMSP1 genes from field isolates at four endemic regions (North, East, West and South) of Thailand.MethodsThe 152 P. vivax infected cases from dried blood spots were DNA extracted and confirmed by species-specific primer sets using multiplex PCR method. PvMSP1 fragments F2 and F3; PvCSP were genotyped using RFLP-PCR method.ResultsTotally amplified DNA which was multiple genotypes for PvMSP1 F2 and PvMSP1 F3 were 12.50% and 8.55%, respectively while PvCSP was 3.95%. The overall frequency of multiple genotypes was 25%. There were 12 allele types of PvMSP1 F2 using AluI enzyme digestion and 8 size variations were found in PvMSP1 F3. The isolates from western region was highly genetic diverse when compare among all isolates. The predominant variant type of PvCSP gene was VK210 type.ConclusionsThe multiple genotypes are common found in Thailand and it might hide the real genotype. PvCSP does not have extensive genetic diversity in this study. However, PvMSP1 marker due to multiple genotypes is difficult to be analyzed. The multiple genotypes findings might stem from population migration and vector species findings. 相似文献

Background
Many opiate users entering British prisons require prescribed medication to help them achieve abstinence. This commonly takes the form of a detoxification regime. Previously, a range of detoxification agents have been prescribed without a clear evidence base to recommend a drug of choice. There are few trials and very few in the prison setting. This study compares dihydrocodeine with buprenorphine. 相似文献68.

CONTEXT: Radiation exposure is associated with development of thyroid nodules. The long-term risk of thyroid cancer development in irradiated people with thyroid nodules, however, has not been clarified. OBJECTIVE: The objective of this study was to assess the long-term risk of cancer development in irradiated individuals with thyroid nodules. DESIGN, SETTING, AND PARTICIPANTS: This prospective study comprised 2637 atomic bomb survivors (mean age, 59 yr; 1071 men and 1566 women) who participated in the baseline thyroid study of the Nagasaki Radiation Effects Research Foundation from 1984 through 1987. The participants were divided into three groups at baseline by ultrasound findings: 82 cases of solid thyroid nodules other than cancer, 121 cases of thyroid cysts, and 2434 thyroid nodule-free controls. Both the solid nodule and the cyst groups included postoperative cases. In the solid nodule group, 68 cases had ultrasound-detected solid nodules, including 31 cases diagnosed as benign by cytological or histological examination. They were followed for an average of 13.3 yr. MAIN OUTCOME MEASURE: Incident thyroid cancer was measured during an average 13.3-yr follow-up period. RESULTS: During the follow-up period, six thyroid cancer cases (7.3%) were found in the solid nodule group, seven cases in the controls (0.3%), and one case (0.8%) in the cyst group. In 31 cases with solid nodules diagnosed as benign, three cases (9.7%) developed thyroid cancer. The hazard ratio (HR) for cancer development was significantly high at 23.6 [95% confidence interval (CI), 7.6-72.8] in the solid nodule group (HR, 40.2; 95% CI, 9.4-173.0 in 31 people with solid nodules diagnosed as benign) but not in the cyst group (HR, 2.7; 95% CI, 0.3-22.2), after controlling for age and sex. Sex, age, TSH level, thyroglobulin level, radiation dose, nodule volume, and increase in nodule volume did not predict cancer development in the solid nodule group. CONCLUSIONS: Risk of thyroid cancer development is high in atomic bomb survivors with solid thyroid nodules, suggesting the need for careful observation of irradiated individuals with such nodules. 相似文献
