Clinical reports on plasma exchange in the Kidney Center, Tokai University School of Medicine.

There were 72 patients (19 with hepatic failure, 10 with fulminant hepatitis, eight with paraquat poisoning, eight with rheumatoid arthritis, five with myasthenia gravis, four with hyperlipidemia, four with systemic arteriosclerosis including brain infarction, three with pemphigus vulgaris, two with multiple myeloma, two with systemic lupus erythematosus, two cases non-specific Ig-G antibody, two cases medication with an anticancer drug, one with multiple sclerosis, one with Crohn's disease with amyloid kidney and one with chronic myeloblastic leukemia) treated by plasma exchange in the Kidney Center, Tokai University School of Medicine from Jan. 1983 to Dec. 1986. We performed plasma exchange using fresh frozen plasma in 40 cases and Lactate-Ringer's solution containing albumin (4.0-5.0%) in 20 cases as the replacement fluid. In 17 cases, we performed double filtration plasma exchange with the recycle system and no replacement fluid. Although PE therapy did not constitute a basic therapy for hyperlipidemia, pemphigus vulgaris, rheumatoid arthritis, myasthenia gravis, and systemic lupus erythematosus, it was effective in relieving severe clinical symptoms. At the present time, conventional plasma exchange does not improve the survival rate of patients with hepatic failure and fulminant hepatitis. Developments of a new artificial liver support apparatus and identity of many toxic substances in hepatic failure are necessary. No hypotension, hypovolemic shock or other significant complications were experienced.

A clinical trial of removal of bilirubin in blood by Evaflux-2A.

We performed both free and albumin-bound bilirubin removal therapy using the Evaflux-2A and evaluated its clinical effects. The removal rates of total bilirubin in the first and second sessions were 31.4%, and 31.0%, respectively. Our clinical data suggested that plasma exchange using Evaflux-2A and an albumin-added electrolyte solution as the substitute fluid was useful in the treatment of hyperbilirubinemia.

Urinary tract infection in oliguric patients with chronic renal failure.

We studied 182 patients with chronic renal failure by urinalysis and urine cultures. Of the patients 27 per cent had significant bacteriuria (more than 10(5) per ml.), 38 per cent had significant pyuria (more than 10 white blood cells per high power field), 19 per cent had urinary tract infection and 7 per cent had symptomatic urinary tract infection. All 12 patients with symptomatic urinary tract infection had significant bacteriuria and 11 had significant pyuria, while 1 had 5 to 10 white blood cells per high power field. Incidences of urinary tract infection differed depending on the primary renal disease (12, 13, 41 and 67 per cent for chronic glomerulonephritis, diabetic nephropathy, polycystic kidney and chronic pyelonephritis, respectively). Among the patients with chronic glomerulonephritis no significant differences were seen in frequencies of bacteriuria and urinary tract infection between male and female patients or between those who did and did not undergo hemodialysis. Also, no significant correlation was seen between bacteriuria and daily urine output but pyuria was significantly more frequent in oliguric patients or those on hemodialysis.

Autopsy findings in chronic pyelonephritis patients under dialysis--collected from the Annuals of Pathological Autopsy Cases in Japan.

Autopsy findings in chronic pyelonephritis patients on dialysis were studied in 122 cases. The greatest number of cases was in the 50-59 year-old group among males and in the 60-69 year-old group among females. Infection was the most frequent cause of death (39.3%), followed by bleeding (23.5%). The total number of patients with infections and bleeding was 68 cases (55.7%) and 39 cases (32.0%), respectively. Pneumonia and bronchitis were the most frequent (27.0%) in cases with infections and gastrointestinal bleeding was the most frequent (21.3%) in cases with bleeding. The incidence of tuberculosis (16.4%) as a complication was high.

Age and sex distribution in chronic renal failure patients at dialysis induction.

Age distribution at dialysis induction among patients with chronic renal failure was studied in 579 cases. Age distribution differed depending on the primary renal diseases and sex. In chronic glomerulonephritis, males were most numerous in the 30-39 year-old group, followed by the 40-49 and 20-29 year-old groups. They decreased with age. Females showed the same frequencies among the 20-29, 30-39, 40-49, 50-59, 60-69 and 70-79 year-old groups. However, the 50-59 year-old group had the most cases. Among cases of diabetic nephropathy, males were most numerous in the 50-59 year-old group and females in the 60-69 year-old group. Progression of the disease to renal failure seemed to be more rapid in males than in females. Natural history and possible risk factors in patients with chronic renal failure maintained on hemodialysis were discussed.

Metastatic patterns of prostatic cancer. Correlation between sites and number of organs involved.

Prostatic cancer in 1885 autopsy cases was classified according to the number of organs involved in metastasis, and a comparison was made concerning the frequency of metastasis to the various organs. The frequencies of metastasis to the lungs and para-aortic lymph nodes were low in cases with single-organ involvement (4.6% and 2.3%, respectively), but increased rectilinearly in accordance with the number of organs involved and became high in cases with metastasis to three or more organs (49.1% and 21.8% in total, respectively). On the other hand, the frequencies of local extension to the bladder and invasion of the pelvic lymph nodes were high even in cases with single-organ involvement (34.5% and 9.2%, respectively) and were not significantly changed regardless of the number of organs involved. No significant correlation was seen between pelvic and para-aortic lymph node involvement. In cases with single-organ involvement, metastasis to the lumbar spine occurred frequently, but those to the ribs, sternum, and ilium occurred less frequently. There may be multiple metastases in cases with metastases to the para-aortic lymph nodes, sternum, and ilium. The number of metastatically involved organs is useful in analyzing the mode of metastasis.

Autopsy findings in maintenance hemodialysis patients.

From March, 1976 to June, 1983, 22 patients (10 males, 12 females) treated by maintenance hemodialysis were autopsied in our department. Primary diseases of the autopsied cases were chronic glomerulonephritis (12 cases), diabetes mellitus (three cases), hydronephrosis (three cases), systematic lupus erythematosus (two cases), myeloma kidney (one case) and atherosclerosing nephropathy (one case). Direct causes of death in maintenance hemodialysis patients were bleeding (six cases), uremia (three cases), infection (three cases), carcinoma (four cases), heart failure (two cases), myocardial infarction (one case), brain ischemia (one case), cardiac tamponade (one case) and unknown (one case).

Autopsy findings in postoperative acute renal failure patients, collected from the annuals of pathological autopsy cases in Japan.

Autopsy findings in post-surgical acute renal failure cases were studied in 131 cases on diaysis collected from annuals of pathological Autopsy Cases in Japan (1958-1981). Fifty (38.2%) abdominal and 48 (36.6%) cardiovascular operative procedures were the origins of the 131 post-operative acute renal failure patients treated by dialysis. The incidence of acute tubular necrosis was 68.7 per cent. There were 13 non-obstetric cases (19.9%) of acute bilateral cortical necrosis. Direct causes of death in postsurgical acute renal failure patients were mainly infection (61.7%) and bleeding (21.0%) The incidence of patients with infectious disease complicating postsurgical acute renal failure was 60.3 per cent and the rate of those between 20 and 70 years of age was constant. The incidence of patients with bleeding was 45.0 per cent and no significant differences were seen in the 20-70 year age range.

Autopsy findings in diabetic nephropathy patients under dialysis, collected from the annuals of pathological autopsy cases in Japan.

Collected from the Annuals of Pathological Autopsy Cases in Japan (1958-1980), autopsy findings of diabetic patients under dialysis were studied in 103 cases on peritoneal dialysis and 103 cases on hemodialysis. Direct causes of death in 13 cases (12.6%) of the 103 diabetic patients on peritoneal dialysis and in 8 cases (7.8%) of the 103 diabetic patients on hemodialysis was infections, and in seven cases (6.8%) on peritoneal dialysis and 19 cases (18.4%) on hemodialysis was bleeding. The incidence of bleeding in diabetic patients on hemodialysis was significantly higher than that in peritoneal dialysis cases (p less than 0.025). Other direct causes of death in diabetic patients on dialysis included myocardial infarction, uremia, pulmonary edema, liver cirrhosis and carcinoma. No significant difference was seen between peritoneal dialysis and hemodialysis, except the incidence of complications of bleeding and pericarditis.

Autopsy findings in dialysis patients with polycystic disease of the kidney.

Autopsy findings of 98 dialysis patients with polycystic disease of the kidney were studied. The 50-59 year-old group was the largest as well as the 1000g-1990g group of kidney weight. Death due to infections was the most frequent, followed by bleeding. The total number of patients with infections and bleeding was 39 cases (39.8%) and 38 cases (38.8%), respectively. Brain and subarachinoid bleeding seemed to be the most important risk factors. But, the causes of death were nonspecifically related to polycystic renal disease. The total number of patients with polycystic disease of the liver was 51 cases (57.1%) and the mean weight of liver was 1960.2g.

Clinical report of diabetic patients treated by chronic hemodialysis.

Twenty one diabetic patients were treated by chronic hemodialysis (HD) in the seven year period from 1975 to 1982 in our Department. The actual one-year and five-year survival rate for diabetic patients treated by maintenance HD were 76% and 43%, respectively. Blood urea nitrogen and serum creatinine levels at the HD induction were 111.95 +/- 28.51 mg/dl and 10.73 +/- 4.56 mg/dl, respectively. There were complications in the form of blindness in 8 cases (38.1%), peripheral nerve impairment in 17 cases (81.0%), myopathy in 8 cases (38.1%), diabetic gangrene in 3 cases (14.3%) and glaucoma in one case (4.8%).

Secondary hyperparathyroidism in patients on maintenance hemodialysis: study of the N and C-terminal parathyroid hormones.

In 34 dialysis patients without secondary hyperparathyroidism and 10 dialysis patients with secondary hyperparathyroidism, the concentration of parathyroid hormone, total calcium, ionized calcium, inorganic phosphate, total alkaline phosphatase and bone alkaline phosphatase in serum were determined. The following results were obtained: serum N and C-terminal parathyroid hormone levels, serum total and ionized calcium levels, and serum total and bone alkaline phosphatase levels in dialysis patients with secondary hyperparathyroidism were higher than the corresponding values in cases of negative secondary hyperparathyroidism. Serum phosphate levels in dialysis patients with and without secondary hyperparathyroidism did not differ. Serum bone alkaline phosphatase activities were well correlated with serum total alkaline phosphatase activities in patients on hemodialysis.

Secondary hyperparathyroidism in patients on maintenance hemodialysis: study of optimal hemopurification and parathyroidectomy.

We have found that hemofiltration and direct hemoperfusion combined with hemodialysis removed significant amounts of parathyroid hormone. Hemofiltration and direct hemoperfusion combined with hemodialysis seemed to have better effects on secondary hyperparathyroidism. Surgical parathyroidectomy is indicated when medical parathyroidectomy has failed to prevent progressive bone disease. We had ten patients with refractory secondary hyperparathyroidism. In these patients, subtotal parathyroidectomy was attempted. The results obtained were: 1) Subtotal parathyroidectomy was successful in all patients. 2) Preoperative serum parathyroid hormone values were useful for diagnosis of secondary hyperparathyroidism. 3) The average serum N and C-terminal parathyroid hormone values measured preoperatively were 4,491.00 +/- 892.13 pg/ml and 4,580.00 +/- 474.48 pg/ml, respectively. 4) The average N and C-terminal parathyroid hormone values measured postoperatively were 298.60 +/- 128.68 pg/ml and 2,631.00 +/- 719.51 pg/ml, respectively.
