During a four-year period, 17 massively obese patients without clinically apparent systemic disease underwent renal biopsy for marked proteinuria. Clinical information and biopsy results were compared with those in 34 normal-body-weight controls matched for age, sex, and similar presentation. Histopathologic changes characteristic of focal glomerulosclerosis were found in nine (53%) of the obese patients and two (6%) of the controls. In addition, five (29%) of the obese patients had occult diabetic nephropathy, while no diabetic changes were seen in controls. Clinically, obese patients resembled controls in most respects. Serum albumin level, however, was higher than in controls (3.5 +/- 0.2 vs 2.5 +/- 0.1 g/dL). Indeed, obese patients with focal glomerulosclerosis had normal serum albumin levels (4.0 +/- 0.1 g/dL). Thus, primary renal disease in massively obese patients with marked proteinuria differed in several important respects from that seen in normal-body-weight patients with a similar degree of proteinuria.

The isoelectric points of albumin purified by pseudo-ligand chromatography on Affi-Gel Blue were determined simultaneously in serum and urine of 11 normal subjects and 25 diabetic patients, subdivided in groups according to their urinary excretion rates of albumin. Serum albumin was constituted by a single homogeneous peak at 4.7 (pI) in normal subjects, whereas the levels for diabetic patients covered this band and some other microheterogeneous levels, ranging from 3.5 to 7 pI. By affinity chromatography with Concanavalin A-Sepharose and immunoelectrophoretic techniques, all these micro-heterogeneous bands were characterized as glycosyl albumin. In normal subjects and diabetic patients whose urinary excretion rate of albumin was normal or increased only slightly (10 to 100 micrograms/min), the pattern of urinary albumin included a main band with normal pI (4.7) and some remarkable amounts of more anionic bands (pI between 4.0 and 4.7) if compared to the native protein, which was characterized as glycosyl albumin. Such a difference was not detected in urines of diabetic patients with clinical nephropathy. These results indicate that the non-enzymatic glycosylation of albumin is a main determinant of the excretion of this protein into urine, in spite of the anionic electrical charge. We describe also the renal selectivity properties in humans that may be viewed as a model for the study of renal disease, but the role of such a mechanism in early diabetic nephropathy remains unknown.

A 72-year-old woman with diabetic nephropathy was hospitalized with peripheral edema in the extremities and weight increase. After diuretics and human serum albumin administration, her condition improved. From the 15th day she had run a subfever and her breathing was diminished in the left lower lung field. A plain chest X-ray film showed pleural effusion over the left lung field. The fluid was exudative. Fluid cultures were negative. A tuberculin reaction was negative. Polymerase chain reaction method disclosed mycobacterium avium complex, indicating rare pleuritis due to mycobacterium avium complex. Eighteen days after chemotherapy, pleural effusion disappeared. Although her hemoglobin A1c (HbA1c) levels were maintained from 6.0 to 6.5% over 4 years, urinary albumin excretion levels and serum creatinine levels increased, indicating deteriorating diabetic nephropathy. Serum albumin levels remained low (3.3-3.6 g/dl). Malnutrition, impaired cellular immunity and apparently abnormal microvascular circulation due to diabetes mellitus may consequently have induced pleuritis due to mycobacterium avium complex.

Since its experimental introduction in 1960, hemodialysis has become a widely performed and relatively safe procedure. Therapeutic strategies have been developed, and the numbers of long-term survivors of hemodialysis therapy have been increasing. Hemodialysis therapy was introduced at Sangenjaya Hospital in October 1970, and the 16 patients who have survived for more than 30 years on hemodialysis therapy since its introduction at the hospital were enrolled in this study to investigate the characteristics of long-term hemodialysis patients. For comparison, 50 patients on hemodialysis for less than 30 years were also studied (21 patients with <10 years hemodialysis, 13 with 10-20 years hemodialysis and 16 with 20-30 years hemodialysis). Background information (age, gender, and cause of renal disease), dialysis dose (single pool [sp.] Kt/V), mineral metabolism (serum phosphate), anemia management (serum hemoglobin), and nutrition (serum albumin and reduced interdialytic weight gain) were assessed. Hemodialysis was instituted at 28.7 +/- 6.4 years of age. The primary cause of end-stage renal disease was chronic glomerulonephritis in all of the patients except one, and in that patient it was polycystic kidney disease. As an index of the dialysis dose, sp. Kt/V was 1.2 +/- 0.11. As an index of mineral metabolism, serum phosphate was 5.4 +/- 0.9 mg/dL. As an index of anemia management, serum hemoglobin was 10.2 +/- 1.2 g/dL. As indexes of nutrition, serum albumin was 4.0 +/- 0.2 g/dL and interdialytic weight gain was 4.43 +/- 1.36%. The sp. Kt/V-value, serum phosphate, serum hemoglobin and interdialytic weight gain did not differ between the four different hemodialysis duration groups. Serum albumin was lower in the >30 group (4.0 +/- 0.2 g/dL) than in the <10 group (4.2 +/- 0.3 g/dL) (P = 0.046). As the duration of hemodialysis has increased, the age at hemodialysis induction has become younger. The cause of the renal failure was chronic glomerulonephritis in most of the cases. None had diabetic nephropathy. Improvement of the prognosis of patients with diabetic nephropathy is required. Most of the indexes of these patients nearly satisfied the recommended values.
