Staphylococcus aureus remains a prominent cause of community- and hospital-acquired infection. This study reviewed 162 cases of S. aureus infection occurring in 120 adults who were hospitalized at a Veterans Affairs Medical Center and referred for consultation to the Infectious Disease Service. There were 37 cases of skin and soft tissue infection, 5 pyomyositis, 34 osteomyelitis, 13 septic arthritis, 19 pneumonia, 3 empyema, 5 pyelonephritis, 37 vascular infection, 3 epidural abscess, and 6 miscellaneous infections. Bacteremia was documented in 56 of 119 (47%) cases in which blood cultures were obtained, indicating the serious nature of the infections in many cases. Staphylococcus aureus is widely prevalent in healthy persons. Given its ubiquity and the capacity to cause a broad array of infections, an effective host response must play an important role in preventing infection. This host response is immunologically nonspecific, in that it depends upon the effectiveness of mechanical barriers to invasion and, once invasion takes place, the interaction of PMN, complement, and antibody that is probably present in serum of all immunologically competent adults rather than sensitization of B or T lymphocytes by any identifiable antigens specific to S. aureus. Analysis of the present cases calls attention to S. aureus as an opportunistic pathogen, 1 that only infrequently causes serious infection in otherwise healthy persons. Nearly every patient in this series had 1 or more medical condition thought to predispose to infection; 279 such conditions were identified, representing an average of 2.3 per person. A break in the natural barrier to infection was also present in the majority of cases, for example, trauma, wound, or pre-existing decubitus ulcer in skin and soft tissue infections; endotracheal tube in pneumonia; and a catheter bypassing urethra or skin in urinary and vascular infections, respectively. The tendency for patients to be infected with S. aureus repeatedly (mean number of infections, 1.4 per patient) reflects the chronicity of many predisposing factors and, perhaps, of colonization as well. Staphylococcus aureus has a special predilection to cause infections involving prosthetic devices, perhaps related to its affinity for fibronectin, laminin, and other serum proteins that can mediate attachment to foreign material; 46 of 162 (28%) infections were associated with the presence of a foreign body. Such infections are difficult to eradicate with antibiotic therapy alone, perhaps because of a change in the metabolic state of adherent bacteria, and removal of the foreign body is generally required for cure.(ABSTRACT TRUNCATED AT 400 WORDS)

Pefloxacin (Abaktal) was used in treatment of 83 patients: 14 patients with acute pyelonephritis, 5 patients with carbuncle of the kidney, 17 patients with postoperative acute pyelonephritis, 3 patients with urosepsis, 7 patients with acute prostatitis, 18 patients with chronic pyelonephritis in the phase of active inflammation, 9 patients with exacerbation of chronic prostatitis, 3 patients with acute cystitis, 2 patients with acute urethritis and 5 patients with epididymo-orchitis. Two dosage forms of pefloxacin were used i.e. tablets of 400 mg and ampoules of 5 ml containing 400 mg of the active substance. The treatment course amounted to 7-14 days. In the patients with inflammatory infectious diseases of the lower urinary tracts (cystitis and urethritis) the treatment course amounted up to 5 days. The results of the treatment with the ampoule solutions were good and satisfactory. With the use of the tablets the results were unsatisfactory in 3 patients (8.1 per cent). Satisfactory bacteriological efficacy of the treatment was stated in 89.5 per cent of the cases. The adverse reactions such as nausea, vomiting, diarrhea and skin eruption were recorded in 5 patients (6 per cent).

Adult male rats were subjected to pyelonephritis by direct kidney intramedullary injection of 0.1 ml saline suspension of 10(5) E. coli. Animals were killed at intervals of 4, 10, 15, 30 and 60 days. Half of each kidney and bladder were cultured in proper bacteriologic media to demonstrate the existence of infection. The other halves were submitted to light microscopy and ultrastructural studies. Immunofluorescence methods were used for the study of connective matrix components, at the initial stage of the inflammatory process (4, 10 and 15 days). Infection was documented by bacteriologic, gross and microscopic findings in all groups following inoculation, and it lasted up to two months. Following the acute inflammatory reaction, fibronectin and type III collagen were deposited in the interstitium of kidneys. Small amounts of type I collagen were found later. Type IV collagen appeared in small quantities, associated with collapse of structures containing basement membranes. Fibronectin became concentrated in re-activated foci. The subsequent scarring and associated focal renal atrophy depended upon the extension of the acute lesion.

The levels of natural antibody against Thomsen-Friedenreich (TF) antigen in sera of patients with various cancers and infectious diseases were examined by an enzyme-linked immunosorbent assay (ELISA) and compared with those of healthy donors. The levels of antibody against TF antigen in sera of patients with adenocarcinomas such as gastric, pancreatic and colorectal cancers were lower than those of patients with hepatoma, pyelonephritis and pneumonia. These findings may reflect the expression of TF-antigen in adenocarcinoma tissues.

We report a case of xanthogranulomatous abscess of the left psoas muscle in a patient who underwent nephrectomy for xanthogranulomatous pyelonephritis four years earlier. Pathogens unlike those usually found in this type of inflammatory reaction were grown on culture. The possible relationship between the two infectious disease processes is analyzed.

From 1966 to 1989 a total of 1,830 cases of bacterial meningitis were recorded at the Department of Infectious Diseases, Rigshospitalet, Denmark. Staphylococcus aureus meningitis accounted for 44 (2.4%) of these cases. Among these, 28 cases were classified as community-acquired S. aureus meningitis. The mortality rate for these cases was 43%. A retrospective study of clinical features and parameters in these community-acquired cases showed the following conditions to be associated with a high mortality risk: advanced age, an underlying condition requiring artificial ventilation, cardiovascular disease and immune deficiencies. At admission, more than 75% of the patients had fever, nuchal rigidity and decreased consciousness. In 57% of cases the focus for the S. aureus infection was endocarditis, pneumonia or skin infections. All the patients had complications due to the meningitis, the major one being insufficient respiration. Autopsy performed in 9 of the 12 fatalities showed endocarditis in 5, pneumonia in 4, and pyelonephritis in 2. All of the brains examined at autopsy showed cerebral and subarachnoid hemorrhage.

The antibiotic policy in 34 Dutch formularies for the treatment of urinary tract infections (UTI) was evaluated. A great variation in antibiotic therapy for the treatment of cystitis was observed: the length of therapy ranged from 1 to 14 days, the agents recommended included older compounds such as trimethoprim-sulfamethoxazole and newer agents such as ciprofloxacin. Recommendations for the treatment of acute pyelonephritis were: a 2 week course of co-trimoxazole in 20 out of 34 formularies. Likewise for acute prostatitis less variation was observed for the length of treatment, i.e. 2 weeks co-trimoxazole, doxycycline or quinolones.

Urinary tract infection is one of the most common infectious diseases in the United States. The term encompasses a wide range of infections, from mild bacteriuria to more severe, complicated upper tract infection. Bacterial virulence factors, host defense mechanisms, and various predisposing factors affect the course and severity of disease. Recent advances in treatment have focused on improved management strategies for specific types of infection (eg, re-current cystitis in women, catheter-related infection). In some cases, the causative organisms are highly predictable and empirical therapy without pretreatment culture is recommended. Other infections (eg, pyelonephritis) require at least 10 days of antimicrobial therapy, and if complications are present, hospitalization may be warranted.

Seven hundred and twenty-seven renal transplant patients are reviewed with respect to the occurrence of urinary tract infection (UTI) after renal transplantation. UTI was defined as the detection of both bacteriuria (10(5) CFU/ml) and pyuria (10 leukocytes/hpf). UTI developed in 11 of the inpatients (20.8%) and in 30 (4.2%) of the outpatients during a one-year period. Among outpatients, 12 had symptomatic infections, comprising seven with acute pyelonephritis and five with acute cystitis. Asymptomatic UTI was detected in 18 patients. In addition, asymptomatic bacteriuria without pyuria was observed in ten (1.4%) patients. UTI was more common in patients with diabetes, and underlying urinary tract complications were present in some patients. Administration of trimethoprim-sulfamethoxazole for about 4 months is suggested to reduce the frequency of UTI in the early period after renal transplantation.

A prospective bacteriological study in 50 children with acute pyelonephritis (APN) (32 girls and 18 boys) and 132 children with lower urinary tract infections (LUTI) (89 girls and 43 boys) was conducted from May to December 1993. Infection was defined by Kass' criteria and APN was defined by the clinical findings. C-Reactive Protein (CRP) assay and postcontrast computed tomography in the presence of a doubt concerning the diagnosis. Escherichia coli (EC) was the bacterial species most frequently isolated (76%). A systematic search for fimbriae protein adhesins (group PAP: pyelonephritis associated pil) on the EC was performed by haemagglutination (human group A red blood cells). 64% of EC possessed fimbriae protein adhesions in the APN group versus only 20% in the LUTI group. In children in whom an organic abnormality was demonstrated, the incidence of fimbriae protein-positive EC was 33% while in children with no organic abnormality, particularly without reflux, 89% of EC presented fimbriae protein. A statistically significant difference was demonstrated between these two groups (p < 0.01). The results of this study illustrate the important role of these adhesins in the development of APN. These adhesins facilitate countercurrent ascension of bacteria in the ureter towards the upper urinary tract and can make the bacteria resistant to certain antibiotics. Testing for fimbriae protein can be useful in clinical practice when investigating the aetiology of APN in the absence of demonstrated reflux. A latex test should soon be available to facilitate the detection of fimbriae protein.
