Adult female (NZB/NZW)F1 hybrid mice with documented autoimmune glomerulonephritis resembling systemic lupus erythematosus were treated with fractionated total lymphoid irradiation (TLI), a modification of the radiotherapeutic regimen currently used for the treatment of Hodgkin disease. After TLI, proteinuria subsided in all mice that had undergone radiotherapy, and the mean survival increased from 359 days in untreated controls to 545 days. It is suggested that TLI should be further investigated as a new approach for immunoregulation of autoimmune disorders.

NZB/NZW mice spontaneously exhibit autoimmune disease similar to that seen in human systemic lupus erythematosus (SLE). We demonstrated that total lymphoid irradiation (TLI) reversed well expressed disease in 6-mo-old NZB/NZW females with a prolongation in survival, decrease in proteinuria, and decrease in anti-DNA antibodies as compared to control animals. Few side effects were observed in the treated group. TLI also prolonged survival in animals with advanced renal disease. These findings suggest that TLI may have application to the treatment of human SLE.

The myeloma kidney is characterized by casts in the distal and collecting tubules. The glomeruli are hardly affected unless amyloidosis is present. When the glomeruli are involved, the proteinuria is nonselective and, in some cases, the whole paraprotein is excreted in the urine. Nephrocalcinosis may be present and focal myeloma cell infiltration in the interstitium is a characteristic, but inconstant, finding. The nephrotic syndrome is extremely rare; if it exists, amyloidosis should be suspected. In contrast to multiple myeloma, the glomeruli are frequently involved in macroglobulinemia of Waldenstrom. Hyaline intracapillary deposits consisting of pure IgM are a characteristic finding as is infiltration of the kidney with lymphoid cells. No characteristic lesion of the kidney has been described in the heavy-chain diseases. Mixed cryoglobulinemia associated with an IgM paraprotein can produce glomerulonephritis that is due to the deposition in the glomeruli of an immune complex consisting of IgG, IgM, and complement.

The toxic effects of cytembena in beagle dogs and rhesus monkeys were investigated with the drug given as single or daily iv injections in doses ranging from 12.5 to 200 mg/kg/day to dogs and 6.25 to 50 mg/kg/day to monkeys. Renal tubular damage was a major drug- and dose-related finding in both species and was clinically indicated by an accompanying uremia, elevated serum creatinine, and proteinuria. In the kidney, the primary lesion was cellular necrosis and desquamation of the distal tubular epithelium in animals given the lowest toxic doses. More severe but similar histologic changes produced by this drug were further characterized by single dose studies in mice which showed renal mitochondrial swelling and disruption plus generalized cell swelling as progressive, subcellular developments which were well established 24 hours after treatment. Cellular regeneration in the renal tubular epithelium was found in dogs and monkeys retained 6 weeks for observation after treatment, although functional recovery was inconsistent. A toxic effect to lymphoid tissue was an additional finding which is described.

A 19-year-old man presented with dyspnea, cough and chest pains; he also complained of nausea, anorexia and postprandial vomiting and reported a 10-kg weight loss. Generalized lymphadenopathy and some rales over both lung bases were noted and a chest radiograph showed bilateral nodular lesions. Persistent leukocytosis, thrombocytosis, proteinuria and anergy to a series of natural antigens were found. The diagnosis of lymphoid interstitial pneumonia was made from material obtained at open lung biopsy. Rapid but incomplete clearing of the lung lesions resulted from steroid therapy; the other abnormalities were corrected gradually, except for the proteinuria, which persisted. The clinical improvement and the ability to work and play have been maintained for the past 20 months.

MRL/lpr and BXSB mice were treated weekly or biweekly with cholera toxin (CT) in intravenous dose of 2 micrograms/mouse. CT treatment notably alleviated proteinuria in MRL/lpr mice, but did not influence the course of lupus nephritis in BXSB male mice. Flow cytometric analysis showed that anomalous B220+ T cells in spleen and thymus were reduced in CT-treated MRL/lpr mice while no significant change in lymphocyte populations was induced in BXSB male mice by this treatment. The suppressive effect of CT treatment on Con A response and the augmentative action on LPS response were observed in MRL/lpr mice. The latter may reflect increased B cells in relative number in the peripheral lymphoid organs. Mitogenic responses in CT-treated BXSB male mice remained unchanged in comparison with those of untreated group. Increased production of IL-6 by spleen cells was demonstrated in MRL/lpr mice treated with CT while in BXSB mice the level of IL-6 was not changed by the treatment with CT. Production of IFN gamma was suppressed by CT treatment in both strains of mice. This may be attributed to the inhibitory effect of CT on IFN gamma-producing Th1 cells as reported previously (Munoz et al, J. Exp. Med. 172: 95-103, 1990). However, CT treatment did not inhibit anti-DNA antibody production in BXSB mice, whereas the autoantibodies were markedly decreased in MRL/lpr mice treated with CT.

This report deals with an unusual case of primary macroglobulinemia with hypercalcemia, chronic renal failure and systemic amyloidosis. In May 1990, a 63-year-old male was transferred to our hospital because of hypercalcemia (13.5 mg/dl) and renal failure. Clinical examinations showed anemia, macroglossia, lymph node swellings and hepatomegaly. Laboratory findings included Bence-Jones (kappa type) proteinuria (0.8 g/day), a monoclonal gammopathy of the IgM-kappa type (2.8 g/dl), a proliferation of lymphoid cells in the peripheral blood (5%) and the bone marrow (59.6%), and lymphomatous involvement of an inguinal lymph node. Serum creatinine concentration was 8.5 mg/dl. The serum levels of parathormone and vitamin D3 metabolites were normal. The roentgenogram of bones showed a compression fracture of the lumbar spine and systemic osteoporosis. The treatment included eel calcitonin, prednisolone and the CHOP regimen, followed by hemodialysis and plasmapheresis. The serum level of IgM increased to 4.6 g/dl. The patient died three months later and postmortem examination demonstrated marked systemic amyloidosis.

A 68-year-old Japanese male (Case 1) and a 59-year-old Japanese male immigrant to Brazil (Case 2) who suffered from subcutaneous eosinophilic lymphoid granuloma (Kimura's disease) of several years duration, developed nephrotic syndrome. Renal biopsy demonstrated membranous nephropathy in Case 1 and minimal-change lesion in Case 2. Both patients were treated with prednisolone for several months. There was complete remission of nephrotic syndrome in eight years in Case 1 and in three months in Case 2. Proteinuria did not reappear after remission of nephrotic syndrome in either case. In contrast subcutaneous tumors subsided in both cases during steroid treatment but again became active immediately following discontinuation of the drug. These clinical observations suggest that, though some common factor(s) might mediate the development of both skin and renal lesions, the mechanism of action on these two target organs may differ, perhaps serving only as a "trigger" for the initiating mechanism of renal disease.

mu-Heavy chain disease (HCD) is a rare monoclonal lymphoid disorder characterized by the failure to assemble a complete IgM immunoglobulin. The mu-heavy chains analyzed to date revealed absence of the variable region and a shortened constant domain. We report the first case of mu-HCD presenting as a benign monoclonal gammopathy. The literature on the 27 reported mu-HCD cases is reviewed, and important clinical and laboratory findings are discussed. The ages of the patients ranged from 15 to 80 years (median, 57.5 years). Twenty-two of 27 patients had an associated lymphoplasma cell proliferative disorder. A monoclonal spike on routine serum protein electrophoresis was found in only 8 of 19 patients. Fourteen of 22 patients had Bence Jones proteinuria, but mu-HCD protein was reported in the urine of only two patients. The survival ranged from less than 1 month to 11 years (median, 24 months).

These studies examined the role of cytokines in chronic autoimmune graft-versus-host disease (GVHD) in B6D2F1 mice injected with lymphoid cells from DBA/2 mice. Anti-interleukin (IL)-4 and anti-interferon (IFN)-gamma mAb, or IFN-gamma, were used in vivo to modulate B cell hyperactivity and disease. Kinetic experiments showed that, 2-3 weeks after induction, GVH mice had 100x elevated serum IgE, while IgG1 and IgG2a were 10x above normal. Early treatment with anti-IL-4 mAb or IFN-gamma decreased serum IgE and IgG1 and had no effect on IgG2a. Anti-IFN-gamma mAb treatment increased serum IgE and IgG1 while reducing IgG2a. This increase in serum immunoglobulins could be correlated with an increased spontaneous secretion of IL-4, IL-5, and IL-6 in spleen cell cultures from anti-IFN-gamma mAb-treated GVH mice. While neither anti-IFN-gamma nor IFN-gamma treatments altered the disease course, anti-IL-4 treatment delayed proteinuria and death in GVH mice. These observations suggest an important role for IL-4 in immune complex-mediated glomerulonephritis in chronic GVHD.
