Although Whipple's disease (WD) has been treated with antibiotics since the early 50s, the best antibiotics and the duration of the therapy have not yet been established. We consider here the pro and cons of the two most commonly used therapies, ceftriaxone followed by trimethoprim-sulfamethoxazole (TMP-SMZ) and hydroxychloroquine in combination with doxycycline. The therapy based on ceftriaxone and TMP-SMZ is efficient in the vast majority of patients for the first few years. However, since reinfections or reactivations can occur, a life-long prophylaxis is necessary and doxycycline is nowadays the best option...

BACKGROUND: To the best of our knowledge, no study has compared gram-negative bacillary hematogenous pyogenic spondylodiscitis (GNB-HPS) with gram-positive coccal hematogenous pyogenic spondylodiscitis (GPC-HPS) regarding their clinical characteristics and outcomes. METHODS: From January 2003 to January 2013, 54 patients who underwent combined antibiotic and surgical therapy in the treatment of hematogenous pyogenic spondylodiscitis were included. RESULTS: Compared with 37 GPC-HPS patients, the 17 GNB-HPS patients were more often found to be older individuals, a history of cancer, and a previous history of symptomatic urinary tract infection...

INTRODUCTION: Nonocclusive mesenteric ischemia (NOMI) has been reported to be associated with high mortality. Early diagnosis of NOMI and prompt restoration of the intestinal blood flow is necessary in order to achieve a favorable outcome. PRESENTATION OF CASE: We present the case of a patient who developed NOMI after autologous blood collection and was treated by selective infusion of the superior mesenteric artery with papaverine, intestinal decompression using a long intestinal tube, the administration of antibiotics, and fluid replacement...

Staphylococcal species are a leading cause of community- and nosocomial-acquired infections, where the placement of foreign materials increases infection risk. Indwelling medical devices and prosthetic implants are targets for staphylococcal cell adherence and biofilm formation. Biofilm products actively suppress proinflammatory microbicidal responses, as evident by macrophage polarization toward an anti-inflammatory phenotype and the recruitment of myeloid-derived suppressor cells. With the rise in prosthetic hip and knee arthroplasty procedures, together with the recalcitrance of biofilm infections to antibiotic therapy, it is imperative to better understand the mechanism of crosstalk between biofilm-associated bacteria and host immune cells...

Chemotherapy induced febrile neutropenia predisposes patients to life threatening infections. We aimed to determine the causative microorganisms, infection focus and antibiotic treatment success in febrile neutropenic children with leukemia. A total of 136 febrile neutropenic episodes in 48 leukemic children were reviewed retrospectively from records. Among 136 febrile neutropenic episodes, 68 (50%) episodes were microbiologically documented. Methicillin sensitive coagulase (-) Staphylococcus aureus were the most common isolates from hemoculture (20...

Inflammation is a central contributor to the pathogenesis of cystic fibrosis (CF) pulmonary disease; so limiting the excessive production of inflammatory mediators represents a major therapeutic strategy for slowing the decline in lung function and improving survival. The macrolide antibiotic azithromycin (AZM) has anti-inflammatory properties and immunomodulatory effects that may be beneficial in CF. The aim of this study was to document the long term use of AZM effect on pulmonary function, nutritional status and number of pulmonary exacerbations in patients with CF...

Lyme borreliosis is caused by Borrelia burgdorferi sensu lato infection, which responds well to antibiotic therapy in the overwhelming majority of cases. However, despite adequate antibiotic treatment some patients report persisting symptoms which are commonly summarised as post-treatment Lyme disease syndrome (PTLDS). In 2005, the Swiss Society of Infectious Diseases published a case definition for PTLDS. We aimed to review the scientific literature with a special emphasis on the last 10 years, questioning whether the definitions from 2005 are still valid in the light of current knowledge...

Outer membrane proteins (OMPs) are unique to Gram-negative bacteria. Several features, including surface exposure, conservation among strains and ability to induce immune responses, make OMPs attractive targets for using as vaccine antigens and immunotherapeutics. LptD is an essential OMP that mediates the final transport of lipopolysaccharide (LPS) to outer leaflet. The protein in Vibrio parahaemolyticus was identified to have immunogenicity in our previous report. In this study, broad distribution, high conservation and similar surface-epitopes of LptD were found among the major Vibrio species...

REVIEW
P Agarwal, A Wielandner
Due to the high morbidity and mortality, nosocomial pneumonia represents a serious risk in hospitalized patients. The increased risk of infections with multidrug-resistant (MDR) pathogens makes a timely diagnosis and prompt therapy indispensable. A newly occurring or progressive infiltrate in any patient who has been hospitalized for more than 48 h should be viewed with suspicion. In contrast to community acquired pneumonia (CAP), radiography plays a limited role in the diagnosis of hospital-acquired pneumonia (HAP)...

Background:Shigella flexneri is a gram negative bacteria that causes the infectious disease "shigellosis." S. flexneri is responsible for developing diarrhea, fever, and stomach cramps in human. Antibiotics are mostly given to patients infected with shigella. Resistance to antibiotics can hinder its treatment significantly. Upon identification of essential therapeutic targets, vaccine and drug could be effective therapy for the treatment of shigellosis. Methods: The study was designed for the identification and qualitative characterization for potential drug targets from S...

A 34-year-old female with left-sided ulcerative colitis (UC) developed severe febrile neutropenia/thrombocytopenia soon after infliximab induction therapy. There was no other plausible cause of the cell line abnormalities other than an accurate temporal association with infliximab administration. Supportive care, broad-spectrum antibiotic, and single dose of filgrastim was given on day 5 of admission due to persistently low absolute neutrophil count and fevers. The cell lines recovered, fever resolved and the patient made a complete clinical recovery...

Many antihypertensive agents have been demonstrated to assist in preservation of kidney function, among them those that modulate calcium channels. Calcium channel blockers may also be of value in protecting hemodialysis patients from complications of sepsis. In diabetic recipients of kidney transplant allografts treated with cyclosporine, calcium channel blockade has been retrospectively linked to improved graft preservation and to fewer episodes of sepsis. This brief review outlines clinical and experimental publications on potential protection from sepsis by addition of calcium channel blockers to standard antibiotic therapy in individuals who may or may not have normal kidney function, or in the presence or absence of immunosuppression...

Despite significant advances in antibiotic therapy and intensive care, sepsis remains the most common cause of death in intensive care units. We previously reported that molecular hydrogen (H2) acts as a therapeutic and preventive antioxidant. Here, we show that preadministration of H2-dissolved water (HW) suppresses lipopolysaccharide (LPS)-induced endotoxin shock in mice. Drinking HW for 3 days before LPS injection prolonged survival in a mouse model of sepsis. The H2 concentration immediately increased in the liver but not in the kidney after drinking HW...

Pediatric pneumonia is one of the most common causes of childhood infection requiring hospitalization and is a substantial driver of antimicrobial use among hospitalized children. About 12-20% of pediatric patients hospitalized with community-acquired pneumonia (CAP) require critical care. Additionally, nosocomial pneumonias (i.e. hospital-acquired and ventilator-associated pneumonias) are responsible for 15-53% of hospital-associated infections and are the most common indication for empiric antibiotics in the pediatric intensive care unit...

Tigecycline has emerged as first line therapy for serious systemic infections due to important pathogens (except P. aeruginosa and Proteus sp.), including multi-drug resistant (MDR) and Gram negative bacilli (GNB), including carbapenem resistant Enterobacteriae. Tigecycline has a "low resistance potential," is protective against C. difficile, and is often the only antibiotic effective against MDR GNB, e.g., Klebsiella sp. Areas covered: Standard dose tigecycline therapy has been used for intra-abdominal infections, complicated skin/skin structure infections (cSSSIs), and CAP...

INTRODUCTION The development of pancreatic infection is associated with the development of a deteriorating disease with subsequent high morbidity and mortality. There is agreement that in mild pancreatitis there is no need to use antibiotics; in severe pancreatitis it would appear to be a logical choice to use antibiotics to prevent secondary pancreatic infection and decrease associated mortality. MATERIALS AND METHODS A non-systematic review of current evidence, meta-analyses and randomized controlled trials was conducted to assess the role of prophylactic antibiotics in acute pancreatitis and whether it might improve morbidity and mortality in pancreatitis...
