Microscopic polyangiitis (MPA) is a rare systemic vasculitis syndrome, which is often accompanied by positive myeloperoxidase-specific
antineutrophil cytoplasmic antibody (MPO-ANCA). While pulmonary involvement of MPA consists mainly of diffuse alveolar hemorrhage
and interstitial pneumonia, bronchiectasis has been reported as a pulmonary lesion in association with MPA. To investigate
the clinical features of patients with MPA, focusing on the presence or the absence of preceding chronic airway diseases (CAD),
we conducted a retrospective observational study of 26 patients in the last 13 years at Saga University Hospital. The clinical
records and radiologic chest examinations were reviewed retrospectively. Pulmonary manifestations were alveolar hemorrhage
in 3 patients (12%) and interstitial pneumonia in 5 (19%). Bronchiectasis, defined by the findings of chest radiograph and
computed tomography, was found in 9 patients (35%). Four patients (15%) with bronchiectasis and one patient (4%) with chronic
bronchitis had experienced chronic bronchial suppuration prior to the onset of MPA. Ten patients were classified as having
chronic airway disease (CAD) before the onset of MPA. MPO-ANCA tended to be lower in the CAD group than in the non-CAD group.
None of the patients in the CAD group had pulmonary hemorrhage or interstitial pneumonia. Only one patient (10%) in the CAD
group died within 90 days of the onset of MPA, while 7 (43.8%) of the non-CAD group died. Our study suggests that MPA may
result in part from CAD and that the clinical course of MPA with CAD may be different from MPA without CAD. 相似文献

Four different types of hollow-fiber membrane plasma separators, constructed of cellulose acetate, polyvinyl alcohol, polyethylene, and polymethylmethacrylate membranes, were evaluated in ex vivo dog perfusions under conditions simulating their clinical use. An arteriovenous (A-V) fistula constructed in the dogs for blood access enabled repeated access to be achieved without surgical intervention. All modules produced transient leukopenia and a reduction of platelet counts. The polymethylmethacrylate module showed minimum reductions of white blood cell counts and CH50. The early leukocyte count reduction in membrane plasmapheresis is most likely related to the magnitude of complement activation by the membrane, as is seen with hemodialysis. 相似文献

Clinical and histologic studies of neuronal intestinal dysplasia 总被引:3,自引:0,他引:3
Over a period of 10 years we have treated 10 patients with neuronal intestinal dysplasia (NID), including 3 in whom the entire intestinal tract was affected by NID, and one in whom small intestinal NID coexisted with total colonic aganglionosis. Three of these 4 patients have died and the one survivor requires parenteral feeding. The six patients with less extensive NID have all been treated successfully; three have required surgery (Duhamel procedure in 2 and colostomy in 1), but 3 responded to conservative measures. We have made detailed histologic studies, including acetylcholinesterase activity in all cases, silver impregnation studies in 4, and immunohistochemical investigation of the peptidergic innervation of the bowel in one case. Follow-up rectal biopsies have not shown any significant morphological changes with time, but functional improvement does occur and we suggest that the myenteric ganglia in NID may have the capacity for functional maturation. 相似文献

Adenylate cyclase responses to pituitary hormones including adrenocorticotropic hormone (ACTH), biogenetic amines, prostaglandin E1 (PGE1), angiotensin II, and glucagon were evaluated in adrenocortical tumors and hyperplastic adrenal tissues, obtained from patients with Cushing's syndrome at surgery, and in normal adrenals. The adenylate cyclase of two normal adrenals was activated only by ACTH and PGE1 among the hormones tested, while that of two hyperplastic adrenal tissues due to excessive pituitary ACTH secretion was stimulated only by ACTH. Of five ACTH-responsive adrenocortical adenomas, in contrast, three were stimulated by norepinephrine, two by epinephrine, one by thyroid-stimulating hormone, and one by luteinizing hormone in addition to ACTH, indicating the presence of multiple receptors for hormones other than ACTH and PGE1 in these four tumors. The cyclase of an ACTH-unresponsive adrenocortical carcinoma ws activated only by PGE1 and not by other hormones including ACTH, whereas that of an ACTH-responsive adrenocortical nodular hyperplasia was stimulated by ACTH and glucagon but not by other hormones including PGE1. These results indicate the presence of multiple receptors for hormones other than ACTH and PGE1, the normal adrenocortical stimulants, in human adrenocortical tumors, particularly in adrenal adenomas, but not in normal and hyperplastic (of whichever an etiology) adrenocortical tissues, suggesting a functional alteration of the cellular membrane receptors in human adrenocortical tumors. 相似文献

The radiographic findings of perirenal amyloidosis have not previously been described. A patient with multiple myeloma and primary amyloidosis (AL) with secondary hydronephrosis as examined on plain film, retrograde ureteropyelography, computed tomography, and magnetic resonance imaging is presented. This case illustrates perirenal amyloidosis and demonstrates the utility of CT and MRI in patient management and surgical treatment. 相似文献

Squamous cell carcinoma antigen (SCCA), a 45-kDa tumor-associated serpin, mainly consists of two highly homologous molecules, SCCA1 and SCCA2, which possess unique proteinase inhibitory properties. Importantly, our previous study demonstrated that an intact structure of SCCAs, and not a cleaved form yielded by interacting with target proteinase, is essential for their function as a serpin. The aim of this study is therefore, to develop a simple method of analyzing expression patterns of intact forms of SCCAs (functional SCCAs) in cervical squamous epithelial tissues and to investigate whether there are any differences in the expression of intact forms of SCCAs between normal and malignant cervical squamous epithelial tissues. We used nondenaturing polyacrylamide gel electrophoresis (PAGE) with immunoblotting. The newly generated antibody, Pab Y2, recognizes only intact form of SCCAs, while the conventional antibody, Mab 27, reacts with the cleaved form of SCCA1 as well as intact forms of SCCAs. Nondenaturing PAGE using Pab Y2 showed that an intact form of SCCAs in the heat-treated tissue extract at 60 degrees C for 2 h was separated into at least five bands, termed as bands A-E from cathode to anode. By comparison with two-dimensional electrophoresis patterns of SCCAs, it was found that the first three bands, i.e. bands A-C, are derived from the intact form of SCCA1, while the other two bands, i.e. band D and E are from the intact form of SCCA2. Specifically, band E, but not band D, of SCCA2 is apparently increased in squamous cell carcinomas compared with normal squamous epithelium. In conclusion, this novel analytical approach will be useful for investigating the different expression patterns of functional SCCAs between normal and malignant cervical squamous epithelial tissues. 相似文献
