A-DROP system might result in underestimation of severity of cases with Legionnaires' disease]

Fifteen cases of legionella pneumonia experienced in our department or associated hospital were included in this study. Each case was classified with the A-DROP system of the Japanese Respiratory Society Guidelines, and guidelines from the Infectious Diseases Society of America (IDSA) (1998) and then we compared the severity of the cases of pneumonia. Although 10 cases were classified as intermediate, 3 as severe, and 2 as extremely severe with the A-DROP system, most cases were classified as severe according to the IDSA guidelines. Among 5 fatal cases, three were ranked as intermediate with the A-DROP system. However all the fatal cases were ranked as severe in the IDSA guidelines. This study suggested that the A-DROP system might underestimate the severity of pneumonia in cases with legionella pneumonia.     

Italian Guidelines for the Diagnosis and Infectious Disease Management of Osteomyelitis and Prosthetic Joint Infections in Adults

Bone and joint infections are recognized as difficult-to-treat infections that result in significant morbidity and mortality among patients and increased healthcare costs. This article presents the recommendations for the diagnosis and management of osteomyelitis and prosthetic joint infections in adults developed by Bone and Joint Infections Committee for the Italian Society of Infectious and Tropical Diseases. It contains data published through to November 2007. An evidence-based scoring system that is used by the Infectious Diseases Society of America was applied to treatment recommendations.     

Clinical practice guidelines for the management of sporotrichosis: 2007 update by the Infectious Diseases Society of America.

Guidelines for the management of patients with sporotrichosis were prepared by an Expert Panel of the Infectious Diseases Society of America and replace the guidelines published in 2000. The guidelines are intended for use by internists, pediatricians, family practitioners, and dermatologists. They include evidence-based recommendations for the management of patients with lymphocutaneous, cutaneous, pulmonary, osteoarticular, meningeal, and disseminated sporotrichosis. Recommendations are also provided for the treatment of sporotrichosis in pregnant women and in children.     

Treatment of fungal infections in hematology and oncology--guidelines of the Infectious Diseases Working Party (AGIHO) of the German Society of Hematology and Oncology (DGHO)

The Infectious Diseases Working Party of the German Society of Haematology and Oncology presents their guidelines for the treatment of fungal infections in patients with hematological and oncological malignancies. These guidelines are evidence-based, considering study results, case reports and expert opinions, using the evidence criteria of the Infectious Diseases Society of America (IDSA). The recommendations for major fungal complications in this setting are summarized here. The primary choice of therapy for chronic candidiasis should be fluconazole, reserving caspofungin or amphotericin B (AmB) for use in case of progression of the Candida infection. Patients with candidemia (except C. krusei or C. glabrata) who are in a clinically stable condition without previous azole prophylaxis should receive fluconazole, otherwise AmB or caspofungin. Voriconazole is recommended for the first-line treatment of invasive aspergillosis. The benefit of a combination of AmB and 5-flucytosine has not been demonstrated except in patients with cryptococcal meningitis. Mucormycosis is relatively rare. The drug therapy of choice consists of AmB, desoxycholate or liposomal formulation, in the highest tolerable dosage. Additional surgical intervention has been shown to achieve a lower fatality rate than with antifungal therapy alone. The role of interventional strategies, cytokines/G-CSF, and granulocyte transfusions in invasive fungal infections are further reviewed. These guidelines offer actual standards and discussions on the treatment of oropharyngeal and esophageal candidiasis, invasive candidiasis, cryptococcosis and mould infections.     

Guidelines for evaluating new antimicrobial agents

Evaluating new antimicrobial agents is governed mostly by interaction between the pharmaceutical industry and the Food and Drug Administration (FDA). Clinical trials are designed to comply with FDA guidelines published in 1977. Basic principles of the 1977 guidelines remain valid; however, changes in the clinical application of anti-infective agents and in the accepted design of clinical trials have occurred. Some changes are inconsistent with the requirements of the 1977 documents. Members of the Infectious Diseases Society of America (IDSA) have the perspective and knowledge needed to assist in updating the 1977 guidelines. It is proposed that the IDSA establish a formal working relationship with the FDA to review and modernize the 1977 guidelines. Industry participation in this process is desirable. If the IDSA can help orchestrate guideline revision in an environment of mutual respect and cooperation, the result may be a more efficient drug-evaluation process that continues to protect the public interest and is more consistent with contemporary concepts of treatment for infectious disease.     

A prospective,multi centre,randomized clinical study to compare the efficacy and safety of Ertapenem 3 days versus Ampicillin - Sulbactam 3 days in the treatment of localized community acquired intra-abdominal infection. (T.E.A. Study: Three days Ertapenem vs three days Ampicillin-sulbactam)

Background  

The recommendations outlined in the latest guidelines published by the Surgical Infection Society (SIS) and the Infectious Disease Society of America (IDSA) regarding the proper duration of antibiotic therapy in patients with intra-abdominal infections are limited and non-specific. This ambiguity is due mainly to the lack of clinical trials on the topic of optimal duration of therapy. It is well known that the overuse of antibiotics has several important consequences such as increased treatment costs, reduced clinical efficacy, and above all, the increased emergence of antibiotic-resistant pathogens. Ampicillin-Sulbactam is a commonly used "first line" antibiotic for intra-abdominal infections. Ertapenem and Ampicillin-sulbactam are recommended as primary treatment agents for localized peritonitis by both the SIS and IDSA guidelines.     

慢性肺曲霉病的诊治进展

慢性肺曲霉病(chronic pulmonary Aspergillosis,CPA)指慢性肺部曲霉菌感染,病程超过3个月,常发生在已有肺部疾病或轻度免疫抑制的患者,并需要比较长的治疗时间。近年来,临床医生对该病的认识不断提高。美国感染病学会曾于2000年提出了曲霉菌病的治疗共识,并在2008年进行了更新,此外尚无 CPA 临床指南发布,2016年欧洲临床微生物学与感染性疾病学会和欧洲呼吸学会(European Society of Clinical Microbiology and Infectious Diseases/European Respiratory Society,ESCMID/ERS)总结了关于 CPA 的前期研究成果,联合制定并发布了首个 CPA 指南。本文对 CPA 的最新诊治进展阐述如下。     

Summary of the Guidelines for Preventing Opportunistic Infections among Hematopoietic Stem Cell Transplant Recipients.

This article contains highlights of "Guidelines for Preventing Opportunistic Infections among Hematopoietic Stem Cell Transplant Recipients: Recommendations of the CDC, the Infectious Diseases Society of America, and the American Society of Blood and Marrow Transplantation," which was published in the Morbidity and Mortality Weekly Report. There are sections on the prevention of bacterial, viral, fungal, protozoal, and helminth infections and on hospital infection control, strategies for safe living following transplantation, immunizations, and hematopoietic stem cell safety. The guidelines are evidence-based, and prevention strategies are rated by both the strength of the recommendation and the quality of evidence that supports it. Recommendations are given for preventing cytomegalovirus disease with prophylactic or preemptive gancyclovir, herpes simplex virus disease with prophylactic acyclovir, candidiasis with fluconazole, and Pneumocystis carinii pneumonia with trimethoprim-sulfamethoxazole. Hopefully, following the recommendations made in the guidelines will reduce morbidity and mortality from opportunistic infections in hematopoietic stem cell transplant recipients.     

Clostridium difficile-associated disease:Adherence with current guidelines at a tertiary medical center

AIM:To assess adherence with the the Society for Healthcare Epidemiology of America(SHEA)/the Infectious Diseases Society of America(IDSA)guidelines for management of Clostridium difficile(C.difficile)-associated disease(CDAD)at a tertiary medical center.METHODS:All positive C.difficile stool toxin assays in adults between May 2010 and May 2011 at the University of Maryland Medical Center were identified.CDAD episodes were classified as guideline adherent or nonadherent and these two groups were compared to determine demographic and clinical factors predictive of adherence.Logistic regression analysis was performed to assess the effect of multiple predictors on guideline adherence.RESULTS:320 positive C.difficile stool tests were identified in 290 patients.Stratified by disease severity criteria set forth by the SHEA/IDSA guidelines,42.2%of cases were mild-moderate,48.1%severe,and 9.7%severe-complicated.Full adherence with the guidelines was observed in only 43.4%of cases.Adherence was65.9%for mild-moderate CDAD,which was significantly better than in severe cases(25.3%)or severe-complicated cases(35.5%)(P<0.001).There was no difference in demographics,hospitalization,ICU exposure,recurrence or 30-d mortality between adherent and non-adherent groups.A multivariate model revealed significantly decreased adherence for severe or severecomplicated episodes(OR=0.18,95%CI:0.11-0.30)and recurrent episodes(OR=0.46,95%CI:0.23-0.95).CONCLUSION:Overall adherence with the SHEA/IDSA guidelines for management of CDAD at a tertiary medical center was poor;this was most pronounced in severe,severe-complicated and recurrent cases.Educational interventions aimed at improving guideline adherence are warranted.

Practice Guidelines for Primary Care of Acute Abdomen 2015

Since acute abdomen requires accurate diagnosis and treatment within a particular time limit to prevent mortality, the Japanese Society for Abdominal Emergency Medicine, in collaboration with four other medical societies, launched the Practice Guidelines for Primary Care of Acute Abdomen that were the first English guidelines in the world for the management of acute abdomen. Here we provide the highlights of these guidelines (all clinical questions and recommendations were shown in supplementary information). A systematic and comprehensive evaluation of the evidence for epidemiology, diagnosis, differential diagnosis, and primary treatment for acute abdomen was performed to develop the Practice Guidelines for Primary Care of Acute Abdomen 2015. Because many types of pathophysiological events underlie acute abdomen, these guidelines cover the primary care of adult patients with nontraumatic acute abdomen. A total of 108 questions based on nine subject areas were used to compile 113 recommendations. The subject areas included definition, epidemiology, history taking, physical examination, laboratory test, imaging studies, differential diagnosis, initial treatment, and education. Japanese medical circumstances were considered for grading the recommendations to assure useful information. The two‐step methods for the initial management of acute abdomen were proposed. Early use of transfusion and analgesia, particularly intravenous acetaminophen, were recommended. The Practice Guidelines for Primary Care of Acute Abdomen 2015 have been prepared as the first evidence‐based guidelines for the management of acute abdomen. We hope that these guidelines contribute to clinical practice and improve the primary care and prognosis of patients with acute abdomen.     

Bacteremia in patients with febrile neutropenia after chemotherapy at a university medical center in Malaysia.

OBJECTIVES: This study was initiated to determine the local profile of blood culture isolates and antibiotic sensitivities in febrile neutropenic patients following chemotherapy, and to establish if any modifications to treatment guidelines are necessary. DESIGN: A total of 116 episodes of febrile neutropenia admitted to the adult hematology ward at a university medical center in Malaysia were studied retrospectively from January 2004 to January 2005. RESULTS: The study showed 43.1% of febrile neutropenic episodes had established bacteremia. Gram-negative bacteria accounted for 60.3% of isolates. Sensitivities of Gram-negative bacteria to the antibiotics recommended in the Infectious Diseases Society of America (IDSA) guidelines were 86.1-97.2%. Coagulase-negative staphylococci were the most common Gram-positive organisms isolated (23.3%). The majority of these were methicillin-resistant. CONCLUSIONS: Carbapenem monotherapy, as recommended in the 2002 IDSA guidelines, is effective treatment for the infections most often encountered at our center. Combination therapy with an aminoglycoside should be considered when using ceftazidime, cefepime or piperacillin-tazobactam, particularly in high-risk patients. Vancomycin should be used if a Gram-positive organism is suspected or isolated.     

Empirical therapy for uncomplicated urinary tract infections in an era of increasing antimicrobial resistance: a decision and cost analysis.

Infectious Diseases Society of America guidelines state that uncomplicated urinary tract infections (UTIs) should be treated empirically with trimethoprim-sulfamethoxazole (TMP-SMZ), unless the community resistance among uropathogens exceeds 10%-20%, in which case a fluoroquinolone (FQ) should be used. However, the data to support this threshold are limited. We performed a cost-minimization and sensitivity analysis to determine what level of TMP-SMZ resistance in a community should trigger FQ use. The mean cost of empirical treatment with TMP-SMZ was US$92 when the proportion of resistant Escherichia coli was 0%, $106 when it was 20%, and $120 when it was 40%. The mean cost of empirical FQ treatment was $107 at current levels of FQ resistance. When >22% of E. coli in a community are TMP-SMZ-resistant, empirical FQ therapy becomes less costly than TMP-SMZ therapy. Treatment guidelines for empirical treatment of UTIs may need modification, and the threshold trigger for empirical FQ use should be raised to >20% TMP-SMZ resistance.     

Practice guidelines for the treatment of candidiasis. Infectious Diseases Society of America.

Infections due to Candida species are the most common of the fungal infections. Candida species produce a broad range of infections, ranging from nonlife-threatening mucocutaneous illnesses to invasive process that may involve virtually any organ. Such a broad range of infections requires an equally broad range of diagnostic and therapeutic strategies. This document summarizes current knowledge about treatment of multiple forms of candidiasis and is the guideline of the Infectious Diseases Society of America (IDSA) for the treatment of candidiasis. Throughout this document, treatment recommendations are scored according to the standard scoring scheme used in other IDSA guidelines to illustrate the strength of the underlying data. The document covers 4 major topical areas. The role of the microbiology laboratory. To a greater extent than for other fungi, treatment of candidiasis can now be guided by in vitro susceptibility testing. The guidelines review the available information supporting current testing procedures and interpretive breakpoints and place these data into clinical context. Susceptibility testing is most helpful in dealing with infection due to non-albicans species of Candida. In this setting, especially if the patient has been treated previously with an azole antifungal agent, the possibility of microbiological resistance must be considered. Treatment of invasive candidiasis. In addition to acute hematogenous candidiasis, the guidelines review strategies for treatment of 15 other forms of invasive candidiasis. Extensive data from randomized trials are really available only for therapy of acute hematogenous candidiasis in the nonneutropenic adult. Choice of therapy for other forms of candidiasis is based on case series and anecdotal reports. In general, both amphotericin B and the azoles have a role to play in treatment. Choice of therapy is guided by weighing the greater activity of amphotericin B for some non-albicans species (e.g., Candida krusei) against the lesser toxicity and ease of administration of the azole antifungal agents. Flucytosine has activity against many isolates of Candida but is not often used. Treatment of mucocutaneous candidiasis. Therapy for mucosal infections is dominated by the azole antifungal agents. These drugs may be used topically or systemically and have been proven safe and efficacious. A significant problem with mucosal disease is the propensity for a small proportion of patients to suffer repeated relapses. In some situations, the explanation for such a relapse is obvious (e.g., relapsing oropharyngeal candidiasis in an individual with advanced and uncontrolled HIV infection), but in other patients the cause is cryptic (e.g., relapsing vaginitis in a healthy woman). Rational strategies for these situations are discussed in the guidelines and must consider the possibility of induction of resistance over time. Prevention of invasive candidiasis. Prophylactic strategies are useful if the risk of a target disease is sharply elevated in a readily identified group of patients. Selected patient groups undergoing therapy that produces prolonged neutropenia (e.g., some bone-marrow transplant recipients) or who receive a solid-organ transplant (e.g., some liver transplant recipients) have a sufficient risk of invasive candidiasis to warrant prophylaxis.     

Treatment of invasive fungal infections in cancer patients—updated recommendations of the Infectious Diseases Working Party (AGIHO) of the German Society of Hematology and Oncology (DGHO)

The Infectious Diseases Working Party (AGIHO) of the German Society of Hematology and Oncology (DGHO) here presents its updated recommendations for the treatment of documented fungal infections. Invasive fungal infections are a main cause of morbidity and mortality in cancer patients undergoing intensive chemotherapy regimens. In recent years, new antifungal agents have been licensed, and agents already approved have been studied in new indications. The choice of the most appropriate antifungal treatment depends on the fungal species suspected or identified, the patient’s risk factors (e.g., length and depth of neutropenia), and the expected side effects. This guideline reviews the clinical studies that served as a basis for the following recommendations. All recommendations including the levels of evidence are summarized in tables to give the reader rapid access to the information.     

Requirements for infrastructure and essential activities of infection control and epidemiology in out-of-hospital settings: a Consensus Panel report.

In 1997 the Association for Professionals in Infection Control and Epidemiology and the Society for Healthcare Epidemiology of America established a consensus panel to develop recommendations for optimal infrastructure and essential activities of infection control and epidemiology programs in out-of-hospital settings. The following report represents the Consensus Panel's best assessment of requirements for a healthy and effective out-of-hospital-based infection control and epidemiology program. The recommendations fall into 5 categories: managing critical data and information; developing and recommending policies and procedures; intervening directly to prevent infections; educating and training of health care workers, patients, and nonmedical caregivers; and resources. The Consensus Panel used an evidence-based approach and categorized recommendations according to modifications of the scheme developed by the Clinical Affairs Committee of the Infectious Diseases Society of America and the Centers for Disease Control and Prevention's Healthcare Infection Control Practices Advisory Committee.     

Methods of granting hospital privileges to perform gastrointestinal endoscopy

This is one of a series of statements discussing the utilization of gastrointestinal endoscopy in common clinical situations. The Standards of Practice Committee of the American Society for Gastrointestinal Endoscopy prepared this text. In preparing this guideline, a MEDLINE literature search was performed, and additional references were obtained from the bibliographies of the identified articles and from recommendations of expert consultants. When little or no data exist from well-designed prospective trials, emphasis is given to results from large series and reports from recognized experts. Guidelines for appropriate utilization of endoscopy are based on a critical review of the available data and expert consensus. Further controlled clinical studies are needed to clarify aspects of this statement, and revision may be necessary as new data appear. Clinical consideration may justify a course of action at variance to these recommendations.
