The uptake and transport of immune complexes (IC) in glomeruli were studied in Arthus-type nephritis induced by ferritin anti-ferritin IC. This experimental nephritis was transient in nature, forming electron dense aggregates and deposits in glomeruli, and was considered to be suitable for the analysis of the glomerular defence against immune complex injury. The IC were taken up and removed from the glomerular circulation first by polymorphonuclear leukocytes and later by macrophages. The IC in the glomerular capillary walls and mesangium were seen to shift slowly from the peripheral part of the glomeruli to the more central and juxtaglomerular area. It is speculated that the glomerular integrity is maintained from the immune complex induced tissue injury through the handling and removal of phlogogenic IC by the blood derived phagocytic system and intrinsic glomerular clearing system. 相似文献

A case of low grade fever developing about a month before the discovery of gastric carcinoma is reported. No findings of infection or collagen disease were revealed. The fever continued for about 3 months, but promptly disappeared after surgical removal of the tumor. A superficial spreading mucosal carcinoma with minimal invasion to the sub-mucosa was seen in the antrum, showing the features of poorly differentiated adenocarcinoma. In addition, unique venous inflammation was recognized beneath and around the neoplasm. Arteries and lymph vessels did not exhibit any inflammatory changes. It was presumed that the gastric carcinoma had induced phlebitis, which subsequently brought about the fever. As to the pathogenetic mechanism, it was suggested that a substance produced by the carcinoma cells flowed into nearby veins to induce the phlebitis. Acta Pathol Jpn 42 : 293-297, 1992. 相似文献

Scurvy is still seen sporadically in the developed world. At a time when subclinical vitamin C deficiency in the general population is being recognized increasingly, the need for clinicians to be aware of this disease remains. We present the case of a 9-year-old boy admitted to hospital with musculoskeletal pain, weakness and changes in the skin and gums. After extensive investigation, he was found to have vitamin C deficiency resulting from a restricted eating pattern. Musculoskeletal complaints are a common mode of presentation of scurvy in children. Failure to appreciate this fact and the risk factors for poor vitamin C intake in the paediatric age group can result in unnecessary and invasive investigations for apparent 'multisystem' disease. 相似文献

BACKGROUND: Nephrotoxic glomerulonephritis is induced by the administration of antibody against the glomerular basement membrane (GBM). We demonstrated previously that Fc receptors for immunoglobulin G (IgG) (FcgammaR) play crucial roles in the induction of accelerated nephrotoxic glomerulonephritis by using FcRgamma-deficient (-/-) mice. Since FcRgamma-/- mice lack the cell surface expression of two activating FcgammaRs, FcgammaRI and FcgammaRIII. The present study aims to identify the FcgammaR responsible for the induction of nephrotoxic glomerulonephritis. METHODS: Accelerated anti-GBM glomerulonephritis was induced in FcgammaRI-/-, FcgammaRIII-/-, and FcRgamma-/- mice by preimmunization with rabbit IgG followed by inoculation of rabbit anti-GBM antibody. Histologic analysis and immunostaining of renal sections were performed. RESULTS: FcgammaRI-/- mice as well as wild-type mice showed severe glomerulonephritis with hypernitremia by the administration of anti-GBM antibody. In contrast, FcgammaRIII-/- mice showed much milder renal involvement, similar to FcRgamma-/- mice. Histologically, FcgammaRI-/- mice showed intracapillary proliferation, glomerular thrombosis, and crescent formation, whereas FcgammaRIII-/- mice showed only glomerular hypercellular changes. The depositions of anti-GBM antibodies, autologous antibodies and complement C3 along the GBM were equally observed among all three FcR-/- mouse types by immunostaining. CONCLUSIONS: Accelerated nephrotoxic glomerulonephritis is induced predominantly through FcgammaRIII but not FcgammaRI. 相似文献

A case of membranous nephropathy with ANCA-associated necrotizing glomerulonephritis during oral administration of PTU for Graves' disease 总被引:1,自引:0,他引:1

We experienced a coincidental case of two types of glomerulopathy associated with Graves' disease. A 64-year-old man, who had been treated with propylthiouracil(PTU) for Graves' disease for 15 years, was admitted to our hospital for macroscopic hematuria and rapidly progressive deterioration of renal function. Although his thyroid function had been within the normal range during treatment, the level of thyrotropin receptor antibody(TRAb) gradually increased from a year before admission. Serological tests revealed that he was positive for myeloperoxidase-antineutrophil cytoplasmic antibody(MPO-ANCA). The renal biopsy specimen showed necrotizing and crescentic glomerulonephritis(GN) superimposed on membranous nephropathy(MN). This is a rare case of MN complicated with ANCA associated crescentic GN in a Graves' disease patient. Association of these two renal alterations was not clearly defined. MN involved with Graves' disease also has been rarely reported. Some reports demonstrated deposition of thyroglobulin and other thyroid related antigens in the glomeruli. In the present case, long-term impairment of Graves' disease and elevation of TRAb might have been responsible for the formation and deposition of thyroid-associated immune complex in the glomeruli. As for crescentic GN, PTU might have induced ANCA-associated GN independently of MN. This case is instructive for considering the relation between Graves' disease and renal injury. 相似文献

Duplex Doppler sonography (ultrasonic equipment: Toshiba SSA-270A) were performed in the patients with various renal disease (male 44, female 32) admitted to our hospital between June 1990 and August 1991. Interlobar arterial blood flow velocity was measured at the side of renal pyramid through a longitudinal scan. Both the maximum blood flow velocity (Vmax) and the minimum blood flow velocity (Vmin) were measured quantitatively and resistive index (RI: defined as (Vmax-Vmin)/Vmax) were calculated. Vmax and Vmin correlated well with the creatinine clearance (Ccr) (r = 0.56, r = 0.66 respectively), whereas RI, by which we can detect Doppler waveform changes, correlated weak with Ccr (r = 0.39). We found twenty-nine patients (40%) with an elevated RI (greater than or equal to 0.70). They had severe renal dysfunction and active pathologic findings in the tubulo-interstitial or vascular compartment of the kidney. Doppler examination of renal blood flow velocity was valuable not only to estimate renal function but also to assess pathophysiology of renal disease. 相似文献

Reducing the impact of rheumatic diseases in childhood is the fundamental objective of every member of the multi-disciplinary team involved in the care of affected children and families. The means by which this objective may be achieved are broad and include the implementation of a range of non-pharmacological therapies to address the effects of rheumatic diseases on the physical development of the child. In addition, the treating team must be aware of the psychosocial impact that these diseases may have and the ways in which this may be minimized. This chapter is devoted to an examination of some of the non-pharmacological issues that arise in the management of the commonest rheumatic disease found in children, juvenile idiopathic arthritis (JIA). Aspects of physical rehabilitation, schooling, medication compliance, pain management and family dynamics are discussed, as are interventions to reduce the impact of this disease and its sequelae, utilizing, where possible, evidence-based principles from the literature. Although specific issues applicable to children with arthritis will be discussed, the broad principles of much of what follows applies to all of the rheumatic diseases in childhood. 相似文献
