High Incidence of Positive Autoantibodies against Thyroid Peroxidase and Thyroglobulin in Patients with Sarcoidosis 总被引:1,自引:0,他引:1
Hirotoshi Nakamura Rieko Genma Tomoko Mikami Akira Kitahara Hiroko Natsume Shinichiro Andoh Shinsuke Nagasawa Kozo Nishiyama Kingo Chida Atsuhiko Sato & Teruya Yoshimi 《Clinical endocrinology》1997,46(4):467-472
OBJECTIVE Although abnormalities of the humoral immune system, such as increased immunoglobulin production, are known in sarcoidosis, the relationship between sarcoidosis and autoimmune disorders is uncertain. We studied the incidence of thyroid autoantibodies and the prevalence of Hashimoto's thyroiditis in patients with sarcoidosis.
PATIENTS AND MEASUREMENTS Sixty-two patients with pulmonary sarcoidosis, diagnosed by a combination of clinical, radiographic and histological findings, were studied. As controls, three groups of subjects aged 40 and over without a known history of thyroid disease (60 patients with pulmonary diseases other than sarcoidosis, 88 hospital employees and 82 company workers), were also analysed. Antibodies against thyroid peroxidase (TPO-Ab) and purified thyroglobulin (Tg-Ab) were measured by radioimmunoassay and antibodies against microsomal antigen (MCHA) and thyroglobulin (TGHA), by haemagglutination.
RESULTS Seventeen of 62 patients (27.4%) had either positive TPO-Ab or Tg-Ab or both. All the patients with positive thyroid autoantibodies were of middle or advanced age, and the incidence of positive TPO-Ab/Tg-Ab in patients with sarcoidosis aged 40 and over was 54.5% in males, 32.4% in females and 37.8% overall. The prevalence was significantly higher in males compared to age-matched control males (0–7.7% in the controls), and in female patients was twice that found in controls (11.8–16.3%). Seven patients had Hashimoto's thyroiditis, indicating that the prevalence was 11.3%, and much higher than that previously reported.
CONCLUSIONS The data show a remarkably high incidence of thyroid autoantibodies in patients of middle or advanced age with sarcoidosis, especially in males, and a higher prevalence of Hashimoto's thyroiditis than in previous reports. 相似文献

We report a case of a very rare disorder, histiocytic sarcoma, from a review of our autopsy cases. The neoplastic cells that
proliferated in organs throughout the body were large cells containing eosinophilic cytoplasm and pleomorphic nuclei with
prominent nucleoli. In the bone marrow, erythrophagocytosis by neoplastic cells was observed. The neoplastic cells were positive
not only for lysozymes and CD68 (KP-1, PG-M1, and Ki-M1P) but also for a monocyte/macrophage-specific marker, CD163. In contrast,
the results of tests for markers of myeloid cells, lymphoid cells, and epithelial cells were all negative. In a polymerase
chain reaction study of paraffin-embedded tissues, analyses for the rearrangement of immunoglobulin heavy chain and T-cell
receptor-γ genes were negative. The current World Health Organization diagnostic criteria for histiocytic sarcoma regard immunohistochemical
investigation as crucial. In this regard, the highly specific positivity for CD163 in this patient indicates that immunohistochemical
staining of CD163 is very useful for the diagnosis of histiocytic sarcoma. 相似文献

One possible means of driving antigen‐specific immune suppression is to expand or induce antigen‐specific FoxP3‐expressing Treg cells. One way of activating and expanding these specialized cells, both in vitro and in vivo, is by strong costimulation via CD28 with an agonistic anti‐CD28 monoclonal antibody, called anti‐CD28 superagonist (CD28SA). However, CD28SA also strongly activates conventional T (Tconv) cells to secrete proinflammatory cytokines and, under certain conditions, causes serious cytokine release syndrome. In this issue of European Journal of Immunology, Tabares et al. [Eur. J. Immunol. 2014. 44: 1225–1236] address how CD28SA can be used for the differential control of human Treg and Tconv cells to suppress immune responses without serious adverse effects. They show that, depending on the dose of the antibody or by comedication of cortico‐steroid, the selective expansion of Treg cells can be achieved without significantly activating Tconv cells to produce inflammatory cytokines. This difference in CD28 signal sensitivity between the two populations can be exploited for better control of immune responses. 相似文献
