A 3-year-old boy with mixed glomerular/tubular proteinuria, mental retardation, and hyperkinesis is described. The proteinuria was discovered at the age of 3 years on urinary mass screening. Most of the urinary protein consisted of albumin, accompanied by increases in low molecular weight proteins, including beta 2-microglobulin and alpha 1-microglobulin. Mixed glomerular/tubular proteinuria is known to be caused by the following conditions: chronic renal failure, chronic pyelonephritis, cadmium poisoning, tubulointerstitial nephritis of various etiologies, and after strenuous, short-term, exhaustive exercise. The present patient did not display any of these disorders or conditions.

In a retrospective analytical study involving 98 children with primary glomerulonephritis who were seen by us at our hospital during a 2-year period from 1984 through 1985 and who had renal biopsy performed previously, attempts were made to correlate pathological findings with both clinical findings and prognosis. The results are summarized as follows: 1) Of 87 patients with asymptomatic chronic glomerulonephritis, glomerular findings were those of minimal change lesion, mesangial proliferative nephritis, MPGN, membranous nephropathy and FGS or sclerosing nephritis in 29.9%, 51.7%, 13.8%, 1.1% and 3.5%, respectively. Among the other 11 patients in whom the diagnosis was made after manifesting the nephritic symptoms, minimal change was noted less frequently and MPGN was detected more frequently than in the aforementioned asymptomatic group. IgA nephropathy was estimated to account for 44.2% of cases of asymptomatic chronic nephritis. 2) Mild mesangial proliferation was observed relatively frequently and severe mesangial proliferation or MPGN rather infrequently in hematuria cases without proteinuria while in those with severe proteinuria minimal change lesion was uncommon and severe mesangial proliferative changes, MPGN or FGS were relatively frequent. 3) In 22 patients with IgA nephropathy and 11 with non-IgA nephritis the severity of glomerular changes was related to the intensity of proteinuria at the time of renal biopsy. 4) A 3 to 5 years' follow-up study of patients with mesangial proliferative nephritis inclusive of IgA nephropathy disclosed that 26-28% of patients became free from urinary abnormalities, 27-37% had persistent hematuria without proteinuria and 24-32% still had proteinuria of 2 plus or above. Patients with milder glomerular changes had a definitely better prognosis than those with severe glomerular lesions.

A 3-year-old Limousin cow was admitted to the University of Georgia Teaching Hospital with a history of chronic weight loss and diarrhea of more than 1 year's duration. Clinical laboratory findings included proteinuria and hypoproteinemia and were suggestive of a nephrotic-like syndrome. Necropsy findings included generalized edema of the visceral organs and diffuse red glistening foci on the capsular and cut surfaces of the cortex of both kidneys. Microscopically, the kidney had hypercellular and hypersegmented glomeruli, focal glomerulosclerosis, periglomerular fibrosis, and tubular nephrosis. The glomerular hypercellularity was confirmed by electron microscopy to be due to increased mesangial cells.

Acute doxorubicin-loaded nanoparticle (DXNP) renal toxicity was explored in both normal rats and rats with experimental glomerulonephritis. In normal rats, 2/6 rats given free doxorubicin (DX) (5 mg/kg) died within one week, whereas all control animals and all rats having received free NP or DXNP survived. A 3 times higher proteinuria appeared in animals treated with DXNP than in those treated with DX. Free NP did not provoke any proteinuria. Two hr post-injection, DXNP was 2.7 times more concentrated in kidneys than free DX (p < 0.025). In rats with immune experimental glomerulonephritis, 5/6 rats given DX died within 7 days, in contrast to animals treated by DXNP, NP, or untreated, which all survived. Proteinuria appeared in all series, but was 2-5 times more intense (p > 0.001) and prolonged after doxorubicin treatment (400-700 mg/day), without significant difference between DXNP and DX. Rats treated by unloaded NP behaved as controls. These results demonstrate that, in these experimental conditions, DXNP killed less animals than free DX, despite of an enhanced renal toxicity of the former. Both effects (better survival and nephrosis) are most probably related to an enhanced capture of DXNP by cells of the mononuclear phagocyte system, including mesangial cells.

A 3-year-old girl with simultaneous presentation of hypertensive encephalopathy, subcutaneous nodules, hepatosplenomegaly and proteinuria was presented. The sarcoidosis was confirmed by histologic demonstration of non-caseating granulomas in the liver, left kidney, a cervical lymph node and subcutaneous nodules. The proteinuria resolved spontaneously. During the six-month period of steroid therapy, the renal mass and hepatosplenomegaly were dissolved but the cervical lymphadenopathy still persisted. The hypertensive state was difficult to control which required a multiple antihypertensive drug regimen.

Familial non-immune-mediated glomerulopathy has recently been recognized as a distinct clinical entity. The presentation includes proteinuria, often in the nephrotic range, microscopic hematuria, and hypertension. Renal function may remain intact long term, or may progress slowly to renal failure. A 3-year-old boy was referred with proteinuria (>8 g/day), microscopic hematuria, and hypertension (184/150 mmHg). Renal function was intact. Diagnostic evaluation uncovered no evidence of systemic disease. A renal biopsy specimen showed no immune deposits in the glomeruli, but fibronectin deposits were detected in the peripheral loop and mesangium by immunofluorescence. The basement membrane was intact. Twelve other family members subsequently were found to have some renal pathology. Renal function was preserved during 7 years of follow-up. The pathogenesis of fibronectin glomerulopathy is discussed.

The omega-3 polyunsaturated fatty acids in fish oil have been shown to produce beneficial effects, such as a reduction in blood pressure, proteinuria, lipid levels and inflammation. Aggregated immunoglobulin A obtained from IgA nephropathy patients induced greater oxygen free radicals in polymorphonuclear leukocytes than other glomerulopathy. All of which may affect the course of IgA nephropathy. Twenty-three adult patients with biopsy proven IgA nephropathy, with proteinuria more than 1 g/day, serum creatinine less than 3 mg/dl and blood pressure control less than 130/80 mmHg were given omega-3 polyunsaturated fatty acids (PUFA) in the form of an Omacor capsule 4 g/day equivalent to eicosapentaenoic acid (EPA) 1.88 g and docosahexaenoic acid (DHA) 1.48 g for 6 months. A 3 to 6 month follow-up was planned, with monthly evaluations of the patients. By six months, the serum triglyceride was significantly reduced (143.45 +/- 62.65 vs 91 +/- 42.89 mg/dl, p = 0.002), serum cholesterol was also reduced but not statistically significant (234.16 +/- 56.29 vs 219.76 +/- 51.25 mg/dl, p = 0.07). There was a trend of increased serum high density lipoprotein (HDL)-cholesterol (39.26 +/- 10.56 vs 42.72 +/- 8.37 mg/dl, p = 0.056). Urine beta-2-microglobulin was elevated in IgA patients and decreased statistically significant after 3 months (453 +/- 580 vs 308 +/- 274 microg/24 h, p < 0.001) and 6 months of fish oil therapy (453 +/- 580 vs 142 +/- 182, p < 0.03) while urine N-acetyl-glucosaminidase (NAG) was of no significant difference both before and after fish oil administration (21 +/- 10 vs 22 +/- 10 and 21 +/- 9 U/24 h, p = 0.08). Plasma malondialdehyde (MDA), the end product of oxidative stress was statistically, significantly decreased (1.09 +/- 0.51 vs 0.89 +/- 0.49 nmol/L, p = 0.003). The study did not show any change in blood pressure, proteinuria, or serum creatinine. The authors conclude from the results of this study that patients with idiopathic IgA nephropathy with proteinuria and mildly reduced GFR did not benefit from short-term treatment with 4 g per day of omega-3 PUFA regarding the total protein excretion and glomerular filtration rate (GFR), but the advantage was the improvement in tubular dysfunction, lipid profiles, and oxidative stress.

Nephrotic syndrome (NS) in a patient with diabetes mellitus (DM) first suggests the diagnosis of diabetic nephropathy. However, glomerular diseases other than diabetic nephropathy have been reported in patients with DM. We present a child with type 1 DM (DM1) associated with NS. A 3 year-old boy who was diagnosed with DM1 developed proteinuria in nephrotic range at the 10th month of follow-up. He had remission on steroid treatment without any problem in glycemic control as he was given tapered daily doses instead of an alternate day regimen. He relapsed at the 7th month of follow-up, and cyclophosphamide treatment brought about remission. He had HLA A24, DR4 and DR53 antigens in common with previously reported cases of DM-NS association. The immunological basis of these diseases may have a causal effect on the association, but the etiopathogenesis is still unclear.

Nineteen cattle with pyelonephritis were examined sonographically. A 3.5- and 5.0-MHz convex transducer was used for percutaneous and a 5.5-MHz linear scanner for transrectal examination. Ultrasonographic changes included enlarged kidneys, echogenic material, and flocculent fluid within a dilated and deformed renal sinus and a poor cortical medullary differentiation. Azotemia was detected in 10 and hematuria and proteinuria in all animals. Microbial culture revealed Corynebacterium renale in eight and Escherichia coli in five cattle. Sonography supplemented the clinical examination and clinicopathological analysis by providing additional information on renal disease in these patients.
