CDC has reported previously surveillance data of severe liver injury in patients treated for latent tuberculosis infection (LTBI) with a daily and twice-weekly 2-month regimen of rifampin with pyrazinamide (RZ). On the basis of these initial reports, CDC cautioned clinicians in the use of this therapy with advised additional monitoring. To estimate the incidence of RZ-associated severe liver injury and provide more precise data to guide treatment for LTBI, CDC collected data from cohorts of patients in the United States who received RZ for the treatment of LTBI during January 2000-June 2002 and for whom data were reported to CDC through June 6, 2003. This report summarizes the analysis, which found high rates of hospitalization and death from liver injury associated with the use of RZ. On the basis of these findings, the American Thoracic Society (ATS) and CDC now recommend that this regimen should generally not be offered to persons with LTBI. The revised ATS/CDC recommendations described in this report have been endorsed by the Infectious Diseases Society of America (IDSA). Clinicians are advised to use the recommended alternative regimens for the treatment of LTBI. Rifampin and pyrazinamide (PZA) should continue to be administered in multidrug regimens for the treatment of persons with active tuberculosis (TB) disease.

Community-acquired pneumonia (CAP) is a costly disease that is associated with significant morbidity and mortality. The growing prevalence of this disease has resulted in various advances in diagnosis and treatment. The most common pathogens of CAP include Streptococcus pneumoniae, Haemophilus influenzae, and atypical pathogens; however, the underlying pathogen often is unknown. Treatment of CAP has evolved because of changing etiologic patterns and increasing antimicrobial resistance among common respiratory pathogens. Among the groups that have established treatment guidelines for CAP are the American Thoracic Society (ATS), the Infectious Diseases Society of America (IDSA), and the Centers for Disease Control and Prevention (CDC). These guidelines establish risk factors associated with drug resistance or infection with specific pathogens. In addition, each guideline provides unique recommendations that are similar in some ways, yet different in others. By understanding the various risk factors for drug resistance and the treatment options endorsed by these guidelines, physicians can treat patients with the most appropriate antimicrobial available.

Multiple severity scoring systems have been devised and evaluated in community-acquired pneumonia (CAP), but a simplified set of prognostic indicators has not yet been developed. Streptococcus pneumoniae is the most frequent aetiological agent of CAP. Our aim was to characterise the outcome in the light of different severity scoring systems and to compare the predictive values of different sets of clinical parameters, using available clinical data for pneumococcal CAP patients. This is a case series retrospective analysis that included consecutive adult pneumococcal CAP patients admitted to Danbury Hospital between 1 January 1996 and 31 December 2000. The aetiology was confirmed by positive sputum and/or blood cultures. The severity assessment included the Pneumonia Outcome Research Trial (PORT) and British Thoracic Society (BTS) scoring systems and other additional parameters. Primary end-points were in-hospital CAP-attributable deaths and length of hospitalisation. N = 151 patients with S. pneumoniae CAP were identified. The mean (+/- standard deviation) age at the time of diagnosis was 68 (+/-15) years. Thirty-three patients (22%) were admitted to the medical intensive care unit. The mean (median) hospitalisation duration was 7.5 (+/-5) days. Door-to-antibiotic mean (median) administration time was 3.7 (2) hours. Most frequent antibiotics used initially were cephalosporins plus/minus macrolides or fluoroquinolones. The mean (+/- standard deviation) PORT score was 105 (+/-37). The observed CAP-related mortality was 9/151 (5.9%, 95% confidence interval: 3-9%). The mortality rate in ICU was 18% (6/33). Sixty-nine patients (45%) had S. pneumoniae bacteraemia an admission. The bacteraemic and non-bacteraemic patients had similar PORT scores (107 vs. 104, P = 0.66), length of hospitalisation (8 vs. 7 days, P = 0.41) and mortality rates (9% vs. 4%, P = 0.30). In conclusion, patients admitted with pneumococcal CAP, although severe and with multiple co-morbidities had low in-hospital mortality rates and lengths of hospitalisation. Neither prior antimicrobial use (or failure) nor antimicrobial resistance contributed to an adverse outcome. S. pneumoniae bacteraemia failed to correlate with need for ICU, length of stay, higher morbidity index or fatal outcome. Low rates of empirical antibiotic use for non-bacterial infections in the local community, implementation of an emergency department protocol for CAP therapy, early recognition of higher risk patients and placement in ICU, use of broad spectrum antibiotics, infectious disease approval or critical pathway restriction for admission orders, could all have combined to effect a good outcome for these patients.

Community-acquired pneumonia (CAP) is a leading cause of death in the world and the sixth most common cause of death in the United States. It is the number one cause of death from infectious diseases in the United States. This article reviews the latest available guidelines from two leading organizations-the Infectious Diseases Society of America (IDSA) and the American Thoracic Society (ATS). The IDSA stratifies patients into three categories and recommends antibiotic management based on assigned categories: outpatients, patients admitted to a general medical floor (GMF), and patients requiring intensive care unit (ICU) admission. The ATS, in contrast, stratifies patients into four major groups based on the presence of two cardiopulmonary diseases, certain modifying risk factors that increase the likelihood of acquiring specific infections (such as with drug-resistant Streptococcus pneumoniae, enteric gram-negative organisms, or Pseudomonas aeruginosa), and also based on the site of treatment (such as outpatient setting, GMF, and ICU).

The diagnosis and treatment of Community Acquired Pneumonia (CAP) are controversial issues, without evidence of solid consensus, reflected in the proliferation of Clinical Practice Guidelines proposing a wide range of recommendations. The aim of this study was the clinical validation of five of the most widely recognized Clinical Practice Guidelines (published by the British Thoracic Society, American Thoracic Society, Infectious Diseases Society of America, European Respiratory Society and Portuguese Society of Pulmonology), in line with the real situation in Portugal, as well as an assessment of the role of macrolides in the treatment of CAP. This study adopted the Delphi method to reach consensus from a panel of 20 Portuguese experts in the treatment of CAP, 16 of which participated actively in the study. A questionnaire with all the management options recommended by the five guidelines was distributed to the experts, who reported their degree of agreement with each recommendation on a 9-point Likert scale. The opinions of the specialist panel are reported, as well as the level of consensus and degree of sufficiency of each management option. The results of this study allowed the identification of the management options receiving a high level of acceptance among Portuguese physicians, as well as the estimation of epidemiological parameters, the definition of standards of care and the identification of the most relevant characteristics for the initial selection of antibiotics for empirical therapy. Erythromycin presents disadvantages in almost all characteristics, compared to advanced generation macrolides. Among these, azithromycin meets the panel of experts preferences as to antibiotic tolerability, administration schedule and costs better than clarithromycin.

During 1993-2003, incidence of tuberculosis (TB) in the United States decreased 44% and is now occurring at a historic low level (14,874 cases in 2003). The Advisory Council for the Elimination of Tuberculosis has called for a renewed commitment to eliminating TB in the United States, and the Institute of Medicine has published a detailed plan for achieving that goal. In this statement, the American Thoracic Society (ATS), Centers for Disease Control and Prevention (CDC), and the Infectious Diseases Society of America (IDSA) propose recommendations to improve the control and prevention of TB in the United States and to progress toward its elimination. This statement is one in a series issued periodically by the sponsoring organizations to guide the diagnosis, treatment, control, and prevention of TB. This statement supersedes the previous statement by ATS and CDC, which was also supported by IDSA and the American Academy of Pediatrics (AAP). This statement was drafted, after an evidence-based review of the subject, by a panel of representatives of the three sponsoring organizations. AAP, the National Tuberculosis Controllers Association, and the Canadian Thoracic Society were also represented on the panel. This statement integrates recent scientific advances with current epidemiologic data, other recent guidelines from this series, and other sources into a coherent and practical approach to the control of TB in the United States. Although drafted to apply to TB-control activities in the United States, this statement might be of use in other countries in which persons with TB generally have access to medical and public health services and resources necessary to make a precise diagnosis of the disease; achieve curative medical treatment; and otherwise provide substantial science-based protection of the population against TB. This statement is aimed at all persons who advocate, plan, and work at controlling and preventing TB in the United States, including persons who formulate public health policy and make decisions about allocation of resources for disease control and health maintenance and directors and staff members of state, county, and local public health agencies throughout the United States charged with control of TB. The audience also includes the full range of medical practitioners, organizations, and institutions involved in the health care of persons in the United States who are at risk for TB.

This study evaluated the possible changes in antibiotic use that might follow the implementation of British or North American guidelines for the treatment of community-acquired pneumonia (CAP) in The Netherlands. Patients admitted for mild, moderate and severe CAP were evaluated prospectively. Volume of antibiotic use, based upon guidelines of the British Thoracic Society (BTS), the Infectious Diseases Society of America (IDSA) or the American Thoracic Society (ATS), was estimated and compared to current practice. For 248 patients, current antibiotic use was 3087 defined daily doses. Antibiotic use would increase by 38% if based on ATS guidelines, by 23% if based on IDSA guidelines, and by 21% if based on BTS guidelines. The most significant increase in antibiotic use would occur for cases of moderate CAP, with incremental antibiotic costs of 1 750 000-3 500 000 Euros in The Netherlands.

The aim of this study was to evaluate the accuracy of three score systems: the pneumonia severity index (PSI); CURB-65 (confusion; urea >7 mM; respiratory rate > or =30 breaths x min(-1); blood pressure <90 mmHg systolic or < or =60 mmHg diastolic; aged > or =65 yrs old); and modified American Thoracic Society rule for predicting intensive care unit (ICU) need and mortality due to bacteraemic pneumococcal pneumonia. All adult patients (n = 114) with invasive pneumococcal pneumonia at the Karolinska University Hospital, Sweden, 1999-2000, were included in the study. Severity scores were calculated and the independent prognostic importance of different variables was analysed by multiple regression analyses. PSI > or = IV, CURB-65 > or = 2, and the presence of one major or more than one minor risk factor in mATS all had a high sensitivity, but somewhat lower specificity for predicting death and ICU need. The death rate was 12% (13 out of 114). Severity score and treatment in departments other than the Dept of Infectious Diseases were the only factors independently correlated to death. Patients treated in other departments more often had severe underlying illnesses and were more severely ill on admission. However, a significant difference in death rates remained after adjustment for severity between the two groups. In conclusion, all score systems were useful for predicting the need for intensive care unit treatment and death due to bacteremic pneumococcal pneumonia. The pneumonia severity index was the most sensitive, but CURB-65 was easier to use.

The Emergency Department is a critical point of care for patients presenting with signs and symptoms of community-acquired pneumonia (CAP). The initial diagnosis, the decision to admit or discharge, the timing of initiating treatment, and appropriateness of the empirical therapy are key factors in successful management. Rising resistance rates to commonly used CAP antibiotics has complicated empirical treatment. Respiratory fluoroquinolones represent an important therapeutic option for patients with co-morbidities and risk factors for penicillin-, macrolide-, and multi-drug-resistant S. pneumoniae infections. Ensuring appropriate use is required to maintain their high level of effectiveness in key respiratory pathogens. Treatment guidelines from the Infectious Diseases Society of America, American Thoracic Society, and Centers for Disease Control and Prevention are available to assist emergency physicians in developing clinical pathways to ensure appropriate use of available therapies.
