Effects of decontamination of the oropharynx and intestinal tract on antibiotic resistance in ICUs: a randomized clinical trial.

IMPORTANCE: Selective decontamination of the digestive tract (SDD) and selective oropharyngeal decontamination (SOD) are prophylactic antibiotic regimens used in intensive care units (ICUs) and associated with improved patient outcome. Controversy exists regarding the relative effects of both measures on patient outcome and antibiotic resistance. OBJECTIVE: To compare the effects of SDD and SOD, applied as unit-wide interventions, on antibiotic resistance and patient outcome. DESIGN, SETTING, AND PARTICIPANTS: Pragmatic, cluster randomized crossover trial comparing 12 months of SOD with 12 months of SDD in 16 Dutch ICUs between August 1, 2009, and February 1, 2013. Patients with an expected length of ICU stay longer than 48 hours were eligible to receive the regimens, and 5881 and 6116 patients were included in the clinical outcome analysis for SOD and SDD, respectively. INTERVENTIONS: Intensive care units were randomized to administer either SDD or SOD. MAIN OUTCOMES AND MEASURES: Unit-wide prevalence of antibiotic-resistant gram-negative bacteria. Secondary outcomes were day-28 mortality, ICU-acquired bacteremia, and length of ICU stay. RESULTS: In point-prevalence surveys, prevalences of antibiotic-resistant gram-negative bacteria in perianal swabs were significantly lower during SDD compared with SOD; for aminoglycoside resistance, average prevalence was 5.6% (95% CI, 4.6%-6.7%) during SDD and 11.8% (95% CI, 10.3%-13.2%) during SOD (P < .001). During both interventions the prevalence of rectal carriage of aminoglycoside-resistant gram-negative bacteria increased 7% per month (95% CI, 1%-13%) during SDD (P = .02) and 4% per month (95% CI, 0%-8%) during SOD (P = .046; P = .40 for difference). Day 28-mortality was 25.4% and 24.1% during SOD and SDD, respectively (adjusted odds ratio, 0.96 [95% CI, 0.88-1.06]; P = .42), and there were no statistically significant differences in other outcome parameters or between surgical and nonsurgical patients. Intensive care unit-acquired bacteremia occurred in 5.9% and 4.6% of the patients during SOD and SDD, respectively (odds ratio, 0.77 [95% CI, 0.65-0.91]; P = .002; number needed to treat, 77). CONCLUSIONS AND RELEVANCE: Unit-wide application of SDD and SOD was associated with low levels of antibiotic resistance and no differences in day-28 mortality. Compared with SOD, SDD was associated with lower rectal carriage of antibiotic-resistant gram-negative bacteria and ICU-acquired bacteremia but a more pronounced gradual increase in aminoglycoside-resistant gram-negative bacteria.

[Practice guideline prevention, diagnosis and treatment of tuberculosis in patients with an HIV infection]. / Richtlijn preventie, diagnose en behandeling van tuberculose bij patiënten met een hiv-infectie.

An interdisciplinary workgroup from the National Committee for Practical Tuberculosis Control in the Netherlands has written an evidence-based practice guideline on the prevention, diagnosis, and treatment of HIV-infected patients with active tuberculosis or latent tuberculosis infection. The diagnosis and treatment of tuberculosis are effectively the same in patients with or without an HIV infection. The diagnosis is more complex in a patient with an HIV infection due to the effect of the immunodeficiency on diagnostic parameters. Concomitant treatment of tuberculosis and HIV is complicated by drug interactions and overlapping adverse effects. In patients with tuberculosis and an HIV infection, the tuberculosis is preferably treated before antiretroviral therapy is started. The nurse or nurse practitioner in the organisation where the tuberculosis is diagnosed is responsible for supporting the HIV patient with tuberculosis.

Fatal Salmonella enteritidis septicaemia in a rheumatoid arthritis patient treated with a TNF-alpha antagonist.

We report a patient with a rare presentation of extra-intestinal salmonellosis after infliximab therapy for rheumatoid arthritis. We discuss the increasing incidence of primary infections and reactivation of intracellular microorganisms after treatment with TNF-alpha blockage, with emphasis on salmonellosis.
