Our patient, with cirrhosis and chronic renal failure, represents an example of the susceptibility of a compromised host to Aeromonas infections. This patient, however, differs from previously reported cases in at least two important aspects. First, it is possible that her portal of entry was a fresh A-V fistula puncture site rather than an intestinal site. The temporal relationship of exposure to flood water prior to the onset of sepsis lends support to this possibility. Epidemiologic investigation of the dialysis center failed to reveal Aeromonas isolates from cultures of the water supply, machinery, or other patients. Second, this case is unique in that our patient developed a destructive aortic valve endocarditis resulting in valvular perforations and acute aortic insufficiency. Furthermore, this infection was initiated on what appears to have been a previously normal valve. Based on a review of the literature and the virulence demonstrated by A. hydrophila in our patient, we conclude that organisms of the genus Aeromonas are capable of inducing serious human infection. Such infections are more likely to occur in compromised hosts. A. hydrophila has accounted for the majority of reported infections.

Thirty-three patients with chronic hereditary nephritis, obtained from 23 unrelated families, were evaluated with respect to clinicopathologic features. Renal tissue was examined by light microscopy in 25 cases, immunofluorescence in 19 cases, and electron microscopy in 16 cases. The light microscopic findings varied, and foam cells were present in only four cases. Immunofluorescence was negative in all but four cases, and in these the immunomicroscopic pattern was compatible with the findings of end stage glomeruli and hyaline arteriolar sclerosis. Although electron microscopy uniformly showed marked thinning or splitting of the glomerular basement membrane, parallel splitting of the glomerular basement membrane with interposition of electron dense granular particles was seen in only eight cases. Association of glomerular basement membrane splitting with granular particles was observed in four of six patients with IgA nephropathy, in two patients with benign familial hematuria, and in a normal kidney donor. Eleven patients, seven men and four women, had chronic renal failure requiring dialysis. Of five patients who received renal allografts, three are alive, with post-transplant survival ranging from 24 to 70 months. The other two died of septicemia.

We have encountered two cases of late calcification of the porcine heterograft. A patient in chronic renal failure died of sepsis and endocarditis fifteen months after replacement of the mitral and tricuspid valves. At postmortem examination, both heterograft valves exhibited severe calcification and thrombosis. A second patient with rheumatic heart disease and sickle cell disease underwent mitral valve replacement for severe regurgitation. Thirty months later, cardiac catheterization revealed prosthetic valve stenosis. The valve was replaced successfully, and the excised heterograft exhibited severe calcification with restriction of leaflet motion. Although calcification of the porcine heterograft is known to occur in patients with infection or disorders of calcium metabolism, dysfunction of the heterograft is rare in our experience.

This is a retrospective study of 133 episodes of bacteremic infection in 112 hemodialysis patients. The frequency of bacteremic infection was 9.5% in patients with chronic renal failure and 10.9% in patients with acute renal failure. In patients with acute renal failure, pneumonia and intra-abdominal abscess were the most frequent sources of septicemia. Sepsis was usually due to Gram-negative organisms and mortality was high. In patients with chronic renal failure, infection of the shunt or fistula was the most common cause, was frequently due to Staphylococcus organism, and had a more favorable survival rate. Gram-negative septicemia from a nonaccess source in patients with chronic renal failure was associated with a higher mortality. Bacterial endocarditis and septic pulmonary emboli occurred in 3.6% of septic episodes and 0.35% of patients at risk and had very low mortality. A low threshold for obtaining blood cultures and early antibiotic treatment are believed to be important in the treatment of bacteremic infections in patients undergoing long-term hemodialysis.

Patients requiring a major amputation for ischemia are frequently gravely ill. Physiologic amputation obtained by freezing the leg, usually with a tourniquet, will permit delay and intensive preoperative therapy. In an efficient, safe, and convenient method which we have developed and used in 46 patients, a pump circulates antifreeze solution through a specially constructed boot. The last 32 patients so treated have been analyzed as to indications and results. Advantages obtained control of sepsis, correction of diabetic coma, dialysis for chronic renal failure, improvement in congestive heart failure, and improvement in pulmonary function. Four patients had successful below-knee amputations after control of infection that had previously seemed to dictate above-knee amputation. The control of pain and odor, the resultant appreciation of the family, and the lessened demand on nursing staff offer worthwhile benefits in many of the patients, even in some in whom advanced systemic disease prevented survival.

We studied the carriage rate of Staphylococcus aureus in patients receiving long-term hemodialysis and also noted the incidence of shunt infections, bacteremia, and septicemia in colonized patients. Thirty-one of 50 patients (62%) carried S aureus in the nose, throat, or on the skin, of whom 20 patients developed shunt infections; nine infections resulted in episodes of bacteremia. Patients with chronic renal failure not undergoing hemodialysis had a 21% carriage rate. Thus, there is a high carriage rate of S aureus in asymptomatic patients receiving hemodialysis that is probably related to an increased incidence of shunt infections and bacteremia.

All cases of persistent renal failure in infants less than 1 year of age were reviewed to determine whether the prognosis has improved equally for infants as for adults. During a ten-year period, 52 infants were treated by applying uniform therapy; 28, more than half, were less than 4 weeks old. All cases were separated into two groups; 19 infants without and 33 infants with congenital renal or urinary tract anomalies. In 20 patients of the latter group, additional serious anomalies of other organs were present. The age distribution was strikingly different: in 18 of 21 infants, renal anomalies were present, as diagnosed on the first day of life. In contrast, only 3 of 11 infants, 4 to 12 months old, had urinary tract anomalies. In infants without renal anomalies, renal failure was caused by hypotension or shock in 10 of 19 cases, by pyelonephritis or sepsis un 6 of 19. Of this group, eight infants (42%) recovered completely, nine (47%) died. Death occurred within one to two days of hospitalization in all but three cases, caused by shock or sepsis. In this group medical problems that are amenable to therapy have caused either renal failure or contributed to the infant's death. In infants with renal or urinary tract anomalies, renal failure was caused by renal dysplasia or agenesis in 16 of 33 infants, by urinary tract obstruction in 12 of 33. Only three patients (9%) recovered, all older than 4 months, 20 (61%) died, and 10 are living with signs of chronic renal failure. Death usually occurred within one week of hospitalization and, in 16 of 20, it was caused by renal failure and multiple additional anomalies. The multiplicity and complexity of the congenital anomalies in most instances precluded effective, lifesaving therapy. Renal failure in infants is still a serious disease accompained by a high mortality rate in which therapeutic possibilities are limited. No improvement in prognosis can be expected in the near future. Pediatrics, 59:987-994, 1977, RENAL FAILURE, CONGENITAL RENAL ANOMALIES, INFANT, ISCHEMIC RENAL DAMAGE.

A 29-year-old female, with chronic renal failure and chronic bilateral emphysema, was admitted with severe uremia and septicemia secondary to multiple abscesses in the right kidney. Her condition improved after right nephrectomy. Pulmonary function studies showed marked obstructive and restrictive lung disease consistent witht the diagnosis of primary emphysema. On biochemical and histological examination, the liver was found to be normal. Alpha1-antitrypsin could not be demonstrated in the patient's serum at normal pH by any of the known techniques, but protein molecules with alpha1-antitrypsin antigencity were found at pH 4.8; this suggests a pH-dependent structural difference in alpha1-antitrypsin protein. Starch gel electrophoresis gave a multibanding pattern not previously described. A new form of apparent total alpha-1-antitrypsin deficiency is postulated.

With the purpose of establishing the clinicopathologic correlation in pyelonephritis and to discard other interstitial nephrites, with present day morphologic criteria we analysed 63 casos that had been diagnosed as pyelonephritis, following Weiss and Parker's histologic criterion. The clinicopathologic diagnosis of pyelonephritis was confirmed in 12 cases; all of them showed obstructive uropathy and in most of them, there was chronic renal failure. Interstitial nephritis was established in 27 cases, all of them showing septicemia and almost half of the cases showed acute renal failure. Other 20 cases showed tubulointerstitial nephritis secondary to different types of glomerulopathies, fetal glomerulosclerosis, dysplasias, nephrophthisis, radiation nephritis and renal infarct. In 4 cases, the study of sections finer than the original, showed absence of histopathologic lesions. The results of the present study point out the main causes of confusion with the pathological diagnosis of pyelonephritis, the necessity to investigate predisposing uropathy in patients with urinary infection and stresses the importance to establish correlation with clinical and laboratory findings in cases with tubulointerstitial lesions.

Continuous hemodialysis is advantageous for the treatment of renal failure in critically ill patients. This study reports our experience in the treatment of emergencies during chronic renal failure with continuous hemodialysis using a Cuprofane membrane. Eighteen patients with acute decompensations of chronic renal failure were treated with continuous hemodialysis (14 arteriovenous and 4 veno-venous). Procedures lasted a mean of 44.2 h, blood urea nitrogen decreased from 150.3 +/- 49.8 to 60.6 +/- 30.7 mg/dl, metabolic acidosis was corrected raising serum bicarbonate from 10.1 +/- 44 to 17.8 +/- 3.3 mEq/L and hyperkalemia was corrected. Mean ultrafiltration was 239.6 +/- 124.6 ml/h which allowed to withdraw a mean 10.590 ml of ultrafiltrate. Two patients were complicated with femoral artery pseudoaneurysms and one patient with a catheter related sepsis. Global mortality was 16.7%, which compared favorably with the 32.1% predicted mortality according to the Simplified Acute Physiology Score. It is concluded that continuous hemodialysis, a readily available procedure, is suitable for the treatment of emergencies during chronic renal failure.
