Retrospective cohort study.
In summary, recent advances in our ability to diagnose, treat, and prevent recurrences of pneumocystis pneumonia have significantly improved the clinical management of this infection, especially in HIV-1-infected individuals. As current investigations allow our therapeutic armamentarium in this disease to be strengthened even further, it is likely that pneumocystis pneumonia will pose a diminishing threat to those patients currently most susceptible to this infection.
To better understand the epidemiology of bacterial pathogens with particular public health importance in Taiwan, we determined the prevalence of nasal colonization with methicillin-susceptible Staphylococcus aureus (MSSA) and methicillin-resistant S. aureus (MRSA) in a cohort of HIV-infected patients attending two hospital outpatient departments. All HIV-infected patients followed regularly between May and September 1999 were enrolled and cultures of the anterior nares were performed using a dry sponge swab. All confirmed S. aureus isolates underwent antimicrobial susceptibility testing using disk diffusion according to recommendations of the National Committee for Clinical Laboratory Standards. Of a total of 162 outpatients studied, 48 (30%) were found colonized with S. aureus including 39 (24%) colonized with MSSA and 9 (6%) colonized with MRSA. The only factor associated with MSSA colonization was receipt of trimethoprim-sulphamethoxazole which appeared protective (relative risk 0.4, 95% confidence interval [CI(95)] 0.2-0.78, P = 0.006). In contrast, ciprofloxacin use was an independent risk factor for MRSA colonization (conditional odds ratio [OR] 11.9, CI(95) 1.8-77.8, P = 0.010) along with a one-quartile reduction in CD(4) count (OR 3.9, CI(95) 1.1-14.3, P = 0.04). Although MRSA colonization was not associated with hospitalization within the previous three months, the multi-drug resistance pattern of MRSA isolates suggests strains were at some point acquired in the healthcare setting. Our study shows that the rate of S. aureus colonization in Taiwanese HIV-infected outpatients is 30%. Low CD4+ counts are most likely associated with other unmeasured risk factors for MRSA. Antimicrobial use may function alternatively as a protective or risk factor for colonization with S. aureus, depending upon the drugs involved and resistance encountered. Fluoroquinolone use may have an important role in the spread of MRSA from inpatient to outpatient settings.
In this U.S. study, most MRSA isolates in the pediatric CF population were SCCmec II PVL negative. Rates of resistance were low, including to older and orally available antibiotics such as trimethoprim-sulfamethoxazole.
Three cases diagnosed in a Pneumology Section are reported. None of them was affected by AIDS and all of them were initially diagnosed from bronchopneumonia. Empirical antibiotherapy was initiated and because of the unsatisfactory progress, bronchoscopy was performed in all cases and in one case a transthoracic puncture was made. Nocardia spp. was then isolated and this let to began with a specific treatment. All the patients progress satisfactorily in their respiratory infection.
Acute generalized exanthematous pustulosis is a severe eruption which is usually drug related. If the causative drug is discontinued, acute generalized exanthematous pustulosis resolves spontaneously in ten days. The aim of this study was to compare drugs suspected of causing acute generalized exanthematous pustulosis reported to French Pharmacovigilance centres and those reported in the literature.

Some bacteria that possess chromosomally determined AmpC β-lactamases may express these enzymes at a high level following exposure to β-lactams, either by induction or selection for derepressed mutants. This may lead to clinical failure even if an isolate initially tests susceptible in vitro, a phenomenon best characterised by third-generation cephalosporin therapy for Enterobacter bacteraemia or meningitis. Several other Enterobacteriaceae, such as Serratia marcescens, Citrobacter freundii, Providencia spp. and Morganella morganii (often termed the 'ESCPM' group), may also express high levels of AmpC. However, the risk of clinical failure with β-lactams that test susceptible in vitro is less clear in these species than for Enterobacter. Laboratories frequently do not report β-lactam or β-lactamase inhibitor combination drug susceptibilities for ESCPM organisms, encouraging alternative therapy with quinolones, aminoglycosides or carbapenems. However, quinolones and carbapenems present problems with selective pressure for multiresistant organisms, and aminoglycosides with potential toxicity. The risk of emergent AmpC-mediated resistance for non-Enterobacter spp. appears rare in clinical studies. Piperacillin/tazobactam may remain effective and may be less selective for AmpC derepressed mutants than cephalosporins. The potential roles for agents such as cefepime or trimethoprim/sulfamethoxazole are also discussed. Clinical studies that better define optimal treatment for this group of bacteria are required.

Prophylaxis with TMP-SMZ, which is well tolerated, significantly reduces the incidence of bacterial infection following renal transplantation, especially infection of the urinary tract and bloodstream, can provide protection against Pneumocystis carinii pneumonia, and is cost-beneficial. Subnormal absorption of TMP-SMZ in the early posttransplant period mandates 320/1,600 mg daily for optimal benefit. Prophylaxis has little discernible effect on the microflora.
Although liver injury after administration of the trimethoprim-sulfamethoxazole combination is rare, hepatocellular necrosis and cholestasis have developed in a few cases. We describe a patient who developed a severe, prolonged cholestatic reaction after trimethoprim-sulfamethoxazole administration. The findings from serial liver biopsy samples showed characteristic abnormalities of phospholipidosis that have not been previously described for trimethoprim-sulfamethoxazole-related hepatic injury. The most prominent finding on electron microscopic evaluation of the liver was the presence of prominent hepatocyte lysosomal inclusions characterized by concentric arrangements of membranous and lamellated structures. The patient improved after several courses of exchange plasmapheresis, which may have assisted in the removal of toxic drug-lipid complexes. The pathogenesis of this acquired secondary phospholipidosis is unknown. Possible mechanisms include generation of highly lipid-soluble metabolites and inhibition of the lysosomal enzyme phospholipase A1.
Patients with diarrhea due to strains of enterohemorrhagic Escherichia coli (EHEC) (e. g. O157:H7) might be at a higher risk of developing hemolytic uremic syndrome when treated with antimicrobial agents. It has been suggested that this might be due to an increase of release or production of vero or shiga-like toxin from such organisms, possibly as a stress response to antimicrobial agents. The aim of this study was to detect such increases in extracellular toxin in vitro with a newly developed method that exposed EHEC to high sublethal concentrations followed by a recovery phase at progressively lower concentrations. Five strains of EHEC were exposed to continuously changing concentrations of ciprofloxacin, co-trimoxazole, cefixime and tetracycline. The amount of free shiga-like toxin I (SLT-I) released was compared to the amount released from inocula that were not exposed to antibiotics. There were significant differences between the five EHEC strains in the amount of toxin detected after exposure to antimicrobial agents (p less than 0.001). Equally important was the type of antibiotic (p less than 0.001), with ciprofloxacin inducing the largest increase ranging from 169 to 436%, followed by co-trimoxazole, cefixime and tetracycline. In addition, the increases in free toxin correlated with the concentration of the antibiotics (p less than 0.001). The association between antibiotic-induced increases in SLT-I produced by strains of EHEC and certain classes of antibiotics might influence the analysis of future epidemiological studies on risk factors for HUS.

The patients were divided into three groups, each consisting of 17 patients: group 1: a single-dose of piperacillin / tazobactam 4.5 g i. v., group 2: ciprofloxacin 500 mg or cotrimoxazol 960 mg i. v. / p. o. and group 3: varying administration and duration of different kinds of antibiotics as control group. The basic characteristics of the patients such as age, body-mass-index, risk factors, diseases, former surgeries and medication were similar between all three groups. Also there were no significant differences in intraoperative parameters such as operation time, blood loss and other postoperative complications.
We have examined the resistance of Pseudomonas pseudomallei biofilm cells to ceftazidime and cotrimoxazole. A large number of these biofilm cells remained viable at 12 and at 24 h, except in the biofilm treated with 200 times the MIC of ceftazidime. The inherent resistance of P. pseudomallei biofilms to conventional antibiotics may explain the lack of success in the treatment of the chronic manifestations of this bacterial infection.
