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.

We studied 11 patients who had visceral abscesses and in whom acute renal failure developed. All renal biopsies showed a diffuse proliferative and crescentig glomerulonephritis. In seven patients blood cultures were repeatedly negative. Endocarditis could be ruled out in six patients. Seven patients had circulating cryoglobulins; serum complement levels were normal in seven and decreased in four; circulating immune complexes were found in the three patients studied. The evolution of the glomerulonephritis, documented by serial biopsies, closely paralleled the course of the infection. A complete recovery of renal function occurred in four cases in which a rapid and complete cure of the infection was obtained. Of five patients in whom the infection was not cured, four died, and chronic renal failure developed in one. In two patients in whom therapy was delayed, chronic renal failure also developed. Deep suppuration, even in the absence of bacteremia, may be responsible for a severe but possibly reversible glomerulonephritis with circulating immune complexes.

Calcification of small subcutaneous arteries and arterioles is commonly found in patients with chronic renal failure (CRF), but the syndrome of acute ischemic necrosis of the skin and subcutaneous fat supplied by these vessels is relatively uncommon. The necrosis occurs during dialysis and after successful renal transplantation, and it is often fatal. Occlusion of the calcified arteries and associated microvessels by thrombi is reported infrequently, but it is relevant to the necrosis. However, the pathogenesis remains enigmatic. In the patient described here, who had CRF, bacteremia, and laboratory evidence of disseminated intravascular coagulation (DIC), the distribution of thrombi and necrosis was mainly that of the calcified arteries which, therefore, probably played a role in the localization of the thrombi. An increased susceptibility of the endothelium of calcified vessels to the procoagulant effects of sepsis may be a contributing factor.

We reviewed the clinical histories of 14 patients diagnosed of acute obstructive renal failure due to bilateral or unilateral uric calculi in patients with only one functioning kidney for a period of 14 years (1974-1987). Urine was alkalinized in all patients. The increase in urine pH was effective in resolving the obstruction in 12 patients. The alkalinizing methods which succeeded in permeabilizing the urinary tract, considering each functioning kidney independently were: intravenous in 5/21, upstream urethral catheterism in 9/21 and by nephrostomy catheter in 5/21. Surgery was performed in 2 patients. In the later the calculi were of double composition. The most frequent complications were: urinary infection in 7/14 patients, chronic renal failure in 4/14 patients, sepsis in 3/14 patients and bacteremia in 2/14 patients. None of the patients died.

A prospective study of community-acquired pneumonia in adults at Srinagarind Hospital, Khon kaen University was conducted from September 1987 to August 1988. Laboratory specimens were tested for bacterial and mycoplasmal culture, CIE for pneumococcal antigen and serological data for mycoplasma and P. pseudomallei. The results supported by clinical data were evaluated. We could identify the pathogens from 62 of 113 cases (55%). P. pseudomallei was the most frequent etiologic agent (32%) and S. pneumoniae was the second (27%). Overall mortality was 21 per cent and it was high in cases with bacteremia and pneumonia due to P. pseudomallei. Sixty-six per cent of the patients had associated diseases. Diabetes mellitus, chronic renal failure and renal calculi were commonly found in patients with pneumonia due to P. pseudomallei. The results of this study showed the relatively high prevalence of P. pseudomallei pneumonia in our region which was different from other reports.

Listeria monocytogenes bacteremia without meningitis has been reported in patients who have undergone long-term hemodialysis and have transfusional iron overload. On the other hand, cases of Listeria bacteremia without meningitis have occurred sporadically among the acquired immunodeficiency syndrome population, mostly homosexuals. There have been no reports of Listeria meningitis occurring among persons who are antibody positive to human immunodeficiency virus or are intravenous drug abusers having chronic renal failure and undergoing hemodialysis. This patient represents the first case of Listeria bacteremia and meningitis to occur in an intravenous drug abuser who is human immunodeficient antibody positive, is receiving hemodialysis, and has transfusional iron overload.

A patient with chronic renal failure who is undergoing dialysis or renal transplantation is susceptible to a number of infections. Transient, usually asymptomatic bacteremias occur in a wide variety of dental manipulations, particularly those involving the mucous membranes. Certain bacteremias may cause serious complications in these already compromised patients. Therefore, antimicrobial prophylaxis is essential when these patients undergo bacteremia-causing dental procedures.

The morbidity and mortality of hemodialysis by internal central venous catheterization in the subclavian and internal jugular positions are reviewed. A follow-up study was performed in our unit over 10 years (786 catheterizations). The most frequent complications were inadequate flow (7.6%) inadvertent withdrawal (5.6%) and bacteremia (5.1%). The overall complication rate was 27.2%. Kinking (p less than 0.001), bleeding (p less than 0.01) and bacteremia (p less than 0.05) occurred more frequently in patients with chronic renal failure, compared to patients with acute renal failure. Inadvertent withdrawal was the only complication observed more frequently in the internal jugular than in the subclavian position (10.8 vs. 4.3%; p less than 0.01). Bacteremia occurred more frequently after prolonged periods of catheterization (greater than 10 days). No fatal complications were observed. To obtain a more accurate idea about mortality, two supplementary large groups were studied: a review of 11 published series (1,542 catheterizations) and a questionnaire-based survey of 16 dialysis centers (approximately 4,000 catheterizations). Six fatalities were registered: 1 due to septicemia (in the literature review) and 3 due to traumatic perforation of the cardiac or the vessel wall, 1 to septicemia and 1 to air embolism (in the questionnaire-based survey). Based on the three different groups studied, the mortality of catheter dialysis could be estimated to be between 0 and 1.25/1,000 catheterizations.

Infection often complicates renal failure and frequently causes death, but the association between renal failure, impaired immunity and infection has not been proved. A recent study showed that patients on dialysis did not show an expected leucocytic response to infection, suggesting that the blunted response was evidence of the immunocompromised state of the uraemic patient. In this study, the relationship between leucocytic responses and infectious challenge was investigated in an animal model of chronic renal failure. Bacteraemia, peritonitis and a chronic lung infection were induced in normal and uraemic rats; the leucocytic response was then monitored. In all three infections, the total white blood cell response was significantly less in the uraemic animals. Neutrophil numbers actually increased, but this response was disguised by a pronounced depression in lymphocyte numbers. Our conclusion is that, although the leucocytic response of the uraemic host to infection may be depressed, the changes to individual leucocyte components in the peripheral blood are sufficiently characteristic to provide useful evidence of infection.

Laboratory and clinical studies on ceftazidime ( CAZ ), a new cephem antibiotic, were carried out in the field of pediatrics. The results were as follows: Antibacterial activities of CAZ against clinically isolated strains of S. pneumoniae, H. influenzae, E. coli and P. aeruginosa were compared with those of cefotaxime (CTX), ceftizoxime (CZX), latamoxef ( LMOX ), cefoperazone (CPZ) and cefmetazole (CMZ), and also with cefsulodin (CFS) and gentamicin (GM) against P. aeruginosa. Against S. pneumoniae and H. influenzae, CAZ was almost as active as CTX, CZX and CPZ. Against E. coli, it was almost as active as CTX, CZX and LMOX . Against P. aeruginosa, it was almost as active as CFS and GM. Serum concentrations and urinary excretion rates after intravenous bolus injection of CAZ at doses of 20 mg/kg and 10 mg/kg for 5 minutes in each 2 cases (4 cases in total) were determined. The mean serum concentrations of CAZ were 78.9 and 52.0 micrograms/ml at 15 minutes, 38.5 and 27.4 micrograms/ml at 1 hour, and 6.5 and 4.8 micrograms/ml at 4 hours, with serum half-lives (T 1/2) of 1.39 and 1.80 hours respectively. Mean cumulative urinary excretion rate within 6 hours after administration was 84.6%. In a patient with chronic renal failure, serum half-life was 3.22 hours and urinary excretion rate within 6 hours was 22.8% (after intravenous bolus injection of CAZ at a dose of 10 mg/kg). CAZ was administered at a dose of 55.5 mg/kg by intravenous bolus injection to a child with purulent meningitis. The levels of CAZ in the cerebrospinal fluid (CSF) at 1 hour after administration were 2.7-38.9 micrograms/ml with CSF/Serum ratios of 3.2-28.8%. Forty-two pediatric patients with various bacterial infections (pyelonephritis 14, tonsillitis 1, bronchopneumonia 3, pneumonia 17, purulent meningitis 1, bacteremia 2, SSSS 1, enterocolitis 3) were treated with CAZ at a daily dose of 49-222 mg/kg t.i.d. or q.i.d. (as a rule 60 mg/kg t.i.d.). The efficacy rate was 97.6% clinically and 97.8% bacteriologically. No adverse reactions were observed except 1 case with mild diarrhea. Abnormal laboratory findings were also only mild; eosinophilia in 1, slight elevation of GOT in 5 and that of GOT & GPT in 3 cases. These results indicate the usefulness of CAZ in the treatment of bacterial infections in children.
