Host versus graft (HVG) syndrome may be induced in parental strain mice by perinatal inoculations of F1 hybrid spleen cells. The principal manifestations of the disease include thrombocytopaenia, intravascular fibrin deposits, intestinal haemorrhage, hepatic infarcts, lymphosplenomegaly and renal disease. Immune complexes have been shown to be the cause of the renal lesions, and have been implicated as the triggers for disseminated intravascular coagulation. In the present studies of RFM mice perinatally inoculated with (T6 x RFM)F1 spleen cells (RFM/(T6 x RFM)F1 mice), quantitative determinations of serum immunoglobulins (Ig) revealed marked elevations of IgG1, IgG2, IgA and IgM. Electrophoretic analyses revealed the polyclonal pattern which typically follows chronic antigenic stimulation. However, IgG1 levels which reached 29 to 72 times control values suggested disruption of homeostatic mechanisms which control circulating Ig levels. Because antibody responses to histocompatibility antigens were present only occasionally, and then in low titre, it seemed unlikely these antigens were the principal causes of hypergammaglobulinaemia and plasmacytosis. Morphological studies indicated that the elevated levels of Ig seen in end-stage HVG syndrome correlated well with marked plasmacytosis, the third morphological finding in a sequence that included the precocious development of germinal centres and subsequent depletion of thymic-dependent (T) lymphocytes. The fact that spleen cells from RFM/(T6 x RFM)F1 mice were severely impaired in their capacity to cause graft versus host disease in related (T6 x RFM)F1 and unrelated C3H mice provided strong evidence that the HVG reaction resulted in T-cell depletion, rather than specific immunoincompetence.

A 52-year-old Japanese man presented with fever spikes, generalized fatigue, anorexia, and anasarca. The patient was referred for the evaluation of fever of unknown origin in association with swelling of cervical, axillary, and inguinal lymph nodes. He also manifested nephrotic syndrome, acute renal failure, hepatosplenomegaly, massive pleural effusion, ascites, disseminated intravascular coagulation, and hypergammaglobulinemia. C-reactive protein was positive and plasma vascular endothelial cell-derived growth factor (VEGF) and serum interleukin-6 levels were markedly elevated. Lymph node biopsy results showed that findings were compatible with Castleman's disease of hyaline vascular type associated with interfollicular plasmacytosis. In conjunction with the clinical findings, a diagnosis of multicentric Castleman's disease was made. The patient underwent renal biopsy because of nephrotic syndrome, and the results showed proliferation of mesangial cells, lobulation of glomeruli, and tram track pattern of the capillary wall without immune complex deposition. Electron microscopy showed widening of the subendothelial space. No electron-dense deposits were present in both mesangial and subendothelial regions. Pathologic features were compatible with glomerular microangiopathy and membranoproliferative glomerulonephritis-like lesions. With corticosteroid therapy, systemic symptoms disappeared; both VEGF and interleukin-6 levels were normalized, and he went into complete remission of nephrotic syndrome. In this article, the role VEGF plays in the pathogenesis of nephrotic syndrome and glomerular microangiopathy is discussed.

A 62 year old woman was referred to our hospital because of acute renal and liver dysfunction. Prior to admission, she had already been started on hemodyalysis filtration(HDF). She showed facial edema and lumbar pain caused by an Ll compressive fracture. Laboratory examinations revealed hypercalcemia (13.2 mg/dL), hyperammonemia (297 microg/dL) and her serum creatinine, blood urea nitrogen and total bilirubin levels were 3.9 mg/dL, 37.4 mg/dL and 3.2 mg/dL, respectively. Among the components of immunoglobulin, IgA was increased, while IgG and IgM were decreased. Serum immunoelectrophoresis revealed the presence of the IgA kappa type of M component. Punched out lesions were noted on her head radiography. Severe plasmacytosis (60-70 % of total cells) were observed by a bone marrow aspiration test, indicating the diagnosis of multiple myeloma. Steroid pulse therapy was started with dexamethasone (40 mg/day, 3 days), and plasma exchange was performed 8 times with continuous HDF. These treatments failed to control hemodynamics and she died of disseminated intravascular coagulation (DIC). Autopsy demonstrated amyloid-like depositions in perisinusoidal space in the liver. In the kidney, there were nodular lesions in the glomeruli, and depositions in the basement membrane of the uriniferous tubuli. Congo red staining of these organs for amyloid yielded negative results. Immunohistochemical staining gave positive results for IgA and kappa. Electron microscopy revealed granular electron deposits in the glomeruli and tubular basement membrane as well. Taken altogether, the diagnosis of the patient could be light chain deposition disease (LCDD).
