Hematopoietic stem cell transplantation has been considered a risk factor for development of platelet transfusion refractoriness. The objective of this study was to assess the platelet transfusion refractoriness rate in patients undergoing allogeneic hematopoietic stem cell transplantation from different sources. We retrospectively reviewed the charts and transfusion records of patients who underwent allogeneic stem cell transplantation at our institution between 2013 and 2015. The evaluation of post-transfusion platelet count was assessed for each transfusion given, from day of progenitor infusion to day 30 after transplantation...

OBJECTIVES: Kenyan guidelines for antibiotic treatment of pneumonia recommended treatment of pneumonia characterised by indrawing with injectable penicillin alone in inpatient settings until early 2016. At this point, they were revised becoming consistent with WHO guidance after results of a Kenyan trial provided further evidence of equivalence of oral amoxicillin and injectable penicillin. This change also made possible use of oral amoxicillin for outpatient treatment in this patient group...

Papillon-Lefèvre syndrome (PLS) is a rare autosomal recessive disorder of keratinization associated with palmoplantar keratoderma and severe periodontitis resulting in complete edentulism in late adolescence. The pathognomonic dental features of PLS are pathologic migration, hypermobility, and exfoliation of the teeth without any signs of root resorption. It has been suggested that an effective way to treat PLS patients presenting early in the disease progression is extraction of the erupted primary dentition or hopeless permanent teeth followed by antibiotic coverage with periodontal therapy for the remaining teeth...

Recommended management of inhalational anthrax, a high-priority bioterrorist threat, includes antibiotics and antitoxins. Obiltoxaximab, a chimeric monoclonal antibody against anthrax Protective Antigen (PA) is licensed under the U.S. Food and Drug Administration's (FDA's) Animal Rule for treatment of inhalational anthrax. Because of spore latency, disease re-emergence after treatment cessation is a concern and there is a need to understand development of endogenous protective immune responses following antitoxin-containing anthrax treatment regimens...

Predicting competition between antibiotic susceptible wild-type and less susceptible mutant bacteria is valuable for understanding how drug concentrations influence emergence of resistance. Pharmacokinetic-pharmacodynamic (PKPD) models predicting the rate and extent of takeover of resistant bacteria during different antibiotic pressures can thereby be a valuable tool in improving treatment regimens. The aim of this study was to evaluate a previously developed mechanism-based PKPD model for its ability to predict in vitro mixed-population experiments with competition between E...

Sepsis and septic shock remain serious infections with reported mortality rates in excess of forty percent. Timely antibiotic therapy in sepsis and septic shock is recognized as an important determinant of outcome. However, the administration of ineffective empiric treatment (IET) (an initial antibiotic regimen that is not active against the identified pathogen(s) based on in vitro susceptibility testing) is associated with excess mortality compared to effective empiric treatment (EET). We examined all hospitalized patients between January 2010 and October 2015 at Barnes-Jewish Hospital with the presence of a sterile site (blood, or pleural, abdominal, cerebrospinal, synovial, and pericardial fluid) culture positive for Gram-negative (GN) bacteria combined with primary or secondary ICD-9-CM codes for severe sepsis (995...

Clinical development of nonsusceptibility to the lipopeptide antibiotic daptomycin remains a serious concern during therapy for infections caused by vancomycin-resistant Enterococcus faecium (VREfm). The long-acting lipoglycopeptide oritavancin exhibits potent in vitro activity against VREfm although its safety and efficacy in treating clinical VREfm infections have not been established. In this study, novel dosing regimens of daptomycin and oritavancin were assessed against both VREfm and daptomycin-nonsusceptible VREfm isolates in an in vitro pharmacokinetic/pharmacodynamic model...

The world is awash in antibiotic-resistant bacteria. The usefulness of nearly every antibacterial agent available in our hospital pharmacies has been compromised. About half of the recently approved antimicrobial agents for gram-negative pathogens, those pending approval, and those entering clinical development are β-lactam-β-lactamase inhibitor combinations. Thus, we are betting heavily on the efficacy and durability of these agents. However, one needs to be cognizant that poor dose regimen design can result in suboptimal efficacy, on-therapy resistance development, and resistance selection that may harm the activity of all β-lactam-β-lactamase inhibitor combinations...

REVIEW
Mercedes Bonet, Erika Ota, Chioma E Chibueze, Olufemi T Oladapo
BACKGROUND: Bacterial infections occurring during labour, childbirth, and the puerperium may be associated with considerable maternal and perinatal morbidity and mortality. Antibiotic prophylaxis might reduce wound infection incidence after an episiotomy, particularly in situations associated with a higher risk of postpartum perineal infection, such as midline episiotomy, extension of the incision, or in settings where the baseline risk of infection after vaginal birth is high. However, available evidence is unclear concerning the role of prophylactic antibiotics in preventing infections after an episiotomy...
