Renal transplantation reduced circulating parathyroid hormone in recipients of renal allografts. Nevertheless, biochemical and histological evidence of mild hyperparathyroidism persisted up to eight years after renal transplantation despite good graft function. 相似文献

The incidence of hypertension (mean diastolic pressure above 90 mm Hg) was evaluated in 85 patients with renal transplants whose follow-up ranged from 3 to 84 months. Bilateral nephrectomy had been performed in 80 recipients. The proportion of hypertensive subjects rose during the first three months, subsequently stabilised around 50-60% for up to five years, and then decreased slightly during the next two years. Over the years hypertension fluctuated so that one-third of the initially hypertensive patients became normotensive, and over one-third of the initially normotensive patients became hypertensive. The main single aetiological factor was renal failure. A significant relation between steroid dosage and blood pressure was found in only a quarter of the hypertensive patients, and in another quarter no cause could be found. 相似文献

Forty-two patients were followed up after 44 renal transplantations in an effort to evaluate possible benefits from the following protocol: systematic microbiologic and clinical surveillance, early and aggressive research for the cause of suspected infections, refusal to use prophylactic antibiotherapy, and selection of treatment according to the established cause of the infection. During 18,030 days of follow-up 124 infections were recorded, of which 110 were bacterial, 11 viral and 3 protozoal. Eighty originated in the urinary tract, 17 in skin wounds and 10 in the lower respiratory tract. Septicemia occurred three times, and one death due to infection was recorded. In the treatment of bacterial infections patients received antibiotics for 2486 days. Ampicillin (given for 816 days) and "minor" drugs such as sulfonamides and urinary antiseptics (given for 1036 days) were used 74.5% of the time, whereas gentamicin was used only 2.6% of the time (64 days). Combined antibacterial therapy was needed 1.2% of the time (29 days). A restrictive policy regarding anti-biotherapy seems to be beneficial to renal transplant recipients. 相似文献

In a series of 404 consecutive first cadaver kidney transplants performed since 1967 the actuarial five- and 10-year survival of patients were 61% and 47% respectively and of grafts 46% and 36%. In more than four-fifths of the patients surviving these intervals the original cadaveric grafts were functioning at these times, and most of the remainder were sustained by subsequent grafts. Although graft survival has remained static since 1967, patient survival improved. Results for 43 consecutive second cadaver transplants were similar after five years to those of first grafts. These results promote the acceptability of cadaveric transplantation as a long-term treatment for chronic renal failure. 相似文献

We have compared the renal excretion of fluoride in a variety of patients with chronic renal failure maintained with and without protein restriction before and during regular dialysis treatment and after transplantation. The patients tended to continue to excrete normal dietary loads of fluoride quite well until renal function was seriously reduced. From a regression of function on excretion the mean level of creatinine clearance when a normal dietary load of fluoride 0.0526 plus or minus 0.019 mmol/2 h (1.0 plus or minus 0.36 mg/24h) has a 90% chance of being excreted lies around 16 ml/min, a level when most patients with renal failure will be symptomatic. Acute loading of such patients with additional fluoride in the form of sodium fluoride from 40 mg to 60 mg/day showed a twofold to threefold increase of serum fluoride concentrations, slight increases in urinary fluoride excretion, and heavy tissue absorption, suggesting that prior fluoride loading of the skeleton had not taken place. These effects contrasted with those in one patient with normal renal function and with those in one patient with skeletal saturation due to prolonged loading. After renal transplantation fluoride excretion increased but reached normal levels within three months of satisfactory function, suggesting that fluoride loading in renal failure and during regular dialysis therapy had not been excessive. 相似文献

The urinary excretion of factor-VIII-related antigen (VIIIRAg) was measured in 72 patients with kidney transplants and compared with that of two end-products of fibrin-fibrinogen lysis (fragments D and E) to assess their usefulness in monitoring the onset of rejection episodes. Specific and sensitive radioimmunoassays were used to measure the three proteins. Unconcentrated urine samples of 24-hour collections were obtained from 20 healthy subjects, 48 patients with stable transplants, and 24 patients with recent transplants serially followed up from the day of transplantation. Factor VIIIRAg and fragments E and D were not detectable in the urine from healthy subjects but were present in 39%, 60%, and 100% respectively of samples from patients with stable transplants. During 33 acute rejection episodes in 19 patients with recent transplants factor VIIIRAg and fragments E and D were significantly increased above the values observed in patients with stable transplants in 82%, 73%, and 64% of samples respectively; in patients with recent transplants showing no clinical sign of rejection increased excretion of these proteins was observed in 11%, 26%, and 22% of samples respectively. The presence of factor VIIIRAg in urine from patients with kidney allografts suggests that endothelial cell-factor VIII-platelet interactions might pay a key part in the pathogenesis of acute rejection. The results suggest that the assay of factor VIIIRAg in urine is more useful than assays of fragments D and E as a corroborative index of transplant rejection. 相似文献

Out of 250 patients with renal failure, seven (2.8%) treated by regular haemodialysis alone (four) or given cadaveric allografts (three) later showed recovery of function of their own kidneys lasting from one to four years. In the patients receiving haemodialysis alone recovery was easily recognised from their serum creatinine concentrations, but in those with transplants recovery was discovered unexpectedly during radionuclide scanning. These findings suggest that recovery of renal function may be more common than generally recognised, which should be borne in mind when beginning renal replacement treatment and particularly when contemplating bilateral nephrectomy. 相似文献

A 59-year-old woman with primary hyperparathyroidism was found to have a parathyroid adenoma behind the left clavicle. Preoperatively, it appeared as a hypoechoic mass on ultrasonography, as a hot nodule on thallium scintigraphy, and as a high signal on T2-weighted magnetic resonance imaging. Histological, immunohistochemical and ultrastructural studies of the surgically resected tumor revealed a parathyroid adenoma composed mainly of oxyphil cells with production of a parathyroid hormone. Moreover, a multilocular lesion of lymphangiectasia was contained. Hypercalcemia was alleviated postoperatively. These observations corroborated a functioning parathyroid oxyphil cell adenoma. This is the first case report of functioning oxyphil cell adenoma of the parathyroid gland with lymphangiectasia in Japan. 相似文献

The incidence of upper gastrointestinal haemorrhage within four months of renal transplantation was studied in two groups of patients. Thirty patients who received prophylactic cimetidine suffered no episodes of upper gastrointestinal haemorrhage, while six of the 33 patients who did not receive cimetidine suffered haemorrhages and one of them died as a result. The difference between the groups was significant. The results suggest that the prophylactic use of cimetidine in patients receiving renal transplants is worth while. 相似文献
