Antibiotic Treatment of Suspected and Confirmed Neonatal Sepsis Within 28 Days of Birth: A Retrospective Analysis

Neonatal sepsis causes significant mortality and morbidity worldwide. Diagnosis is usually confirmed via blood culture results. Blood culture sepsis confirmation can take days and suffer from contamination and false negatives. Empiric therapy with antibiotics is common. This study aims to retrospectively describe and compare treatments of blood culture-confirmed and unconfirmed, but suspected, sepsis within the University of Utah Hospital system. Electronic health records were obtained from 1,248 neonates from January 1, 2006, to December 31, 2017. Sepsis was categorized into early-onset (≤3 days of birth, EOS) and late-onset (\u3e3 and ≤28 days of birth, LOS) and categorized as culture-confirmed sepsis if a pathogen was cultured from the blood and unconfirmed if all blood cultures were negative with no potentially contaminated blood cultures. Of 1,010 neonates in the EOS cohort, 23 (2.3%) were culture-confirmed, most with Escherichia coli (42%). Treatment for unconfirmed EOS lasted an average of 6.1 days with primarily gentamicin and ampicillin while confirmed patients were treated for an average of 12.3 days with increased administration of cefotaxime. Of 311 neonates in the LOS cohort, 62 (20%) were culture-confirmed, most culturing coagulase negative staphylococci (46%). Treatment courses for unconfirmed LOS lasted an average of 7.8 days while confirmed patients were treated for an average of 11.4 days, these patients were primarily treated with vancomycin and gentamicin. The use of cefotaxime for unconfirmed EOS and LOS increased throughout the study period. Cefotaxime administration was associated with an increase in neonatal mortality, even when potential confounding factors were added to the logistic regression model (adjusted odds ratio 2.8, 95%CI [1.21, 6.88], p = 0.02). These results may not be generalized to all hospitals and the use of cefotaxime may be a surrogate for other factors. Given the low rate of blood culture positive diagnosis and the high exposure rate of empiric antibiotics, this patient population might benefit from improved diagnostics with reevaluation of antibiotic use guideline

Current use of complementary and conventional medicine for treatment of pediatric patients with gastrointestinal disorders

Infants, children, and adolescents are at risk of experiencing a multitude of gastrointestinal disorders (GID). These disorders can adversely affect the quality of life or be life-threatening. Various interventions that span the conventional and complementary therapeutic categories have been developed. Nowadays, parents increasingly seek complementary options for their children to use concurrently with conventional therapies. Due to the high prevalence and morbidity of diarrhea, constipation, and irritable bowel syndrome (IBS) in children, in this review, we decided to focus on the current state of the evidence for conventional and complementary therapies used for the treatment of these diseases in children. Diarrhea treatment focuses on the identification of the cause and fluid management. Oral rehydration with supplementation of deficient micronutrients, especially zinc, is well established and recommended. Some probiotic strains have shown promise in reducing the duration of diarrhea. For the management of constipation, available clinical trials are insufficient for conclusive recommendations of dietary modifications, including increased use of fruit juice, fiber, and fluid. However, the role of laxatives as conventional treatment is becoming more established. Polyethylene glycol is the most studied, with lactulose, milk of magnesia, mineral oil, bisacodyl, and senna presenting as viable alternatives. Conventional treatments of the abdominal pain associated with IBS are poorly studied in children. Available studies investigating the effectiveness of antidepressants on abdominal pain in children with IBS were inconclusive. At the same time, probiotics and peppermint oil have a fair record of benefits and safety. The overall body of evidence indicates that a careful balance of conventional and complementary treatment strategies may be required to manage gastrointestinal conditions in children

Immunomodulatory Effects of Modified Bovine Colostrum, Whey, and Their Combination with Other Natural Products: Effects on Human Peripheral Blood Mononuclear Cells

ABSTRACT: Background: Many natural products have immunomodulatory properties. However, the mechanism of immunomodulatory activities are poorly understood. Objectives: This study evaluated the influence of bovine colostrum products, a whey product, or their combinations with other natural products on human peripheral blood mononuclear cells’ (PBMC) ability to produce cytokines upon activation. Methods: PBMCs were pretreated with ultrafiltered colostrum, nano-filtered bovine colostrum, egg yolk extract, a botanical blend, colostrum + egg yolk extract, colostrum + egg yolk + botanical blend, and fermented whey and then stimulated with lipopolysaccharide or phytohemagglutinin. Cytokine production was measured by the Luminex assay. Results: All study products demonstrated immunomodulatory properties by regulating cytokines production by activated PBMCs. Ultrafiltered colostrum alone displayed the highest immune stimulatory activity. It stimulated proinflammatory cytokine production by lipopolysaccharide-activated PBMCs and suppressed cytokine production by phytohemagglutinin-activated cells. Other study products mainly suppressed cytokine release by both cell types. The immunomodulatory properties depended upon the dose of the products used in the study. Conclusions: All tested products modulated innate and adaptive immune cell activities. Most of the products demonstrated anti-inflammatory properties, except ultrafiltered colostrum, which stimulated the lipopolysaccharide-activated PBMC production of inflammatory cytokines. These products can be potentially used to support overall immune health

Changing Trends in IVIG Use in Pediatric Patients: A Retrospective Review of Practices in a Network of Major USA Pediatric Hospitals

The use of immunoglobulins is gradually increasing. Intravenous immunoglobulins (IVIG) are used as replacement therapy for primary and secondary immune deficiencies, and as an anti-inflammatory and immunomodulatory medication for the treatment of neurologic, dermatologic, and rheumatologic diseases. The objective of this study was to analyze trends in the IVIG use in pediatric patients hospitalized to 47 US-based children\u27s hospitals from 2007 to 2014. IVIG was used for the treatment of \u3e2300 primary diagnoses in 53,648 unique patients. The number of IVIG admissions increased by 30.2% during the study period, while the mean rate of IVIG admissions/100,000 admissions increased only 5.8%. Most patients receiving IVIG were children and adolescents. IVIG was frequently used off-label or for the treatment of FDA-approved indications in children under two years of age and BMT patients \u3c20 years of age. Primary immune deficiencies represented only 1.2% of all IVIG admissions. Pediatric patients with mucocutaneous lymph node syndrome (Kawasaki disease, KD) and idiopathic thrombocytopenic purpura (ITP) were two primary consumers of the IVIG. Another top-ranked indications were acute infectious polyneuritis (Guillain-Barré syndrome, GBS) and prophylaxis of infections in patients receiving antineoplastic chemotherapy. IVIG usage is a dynamic process guided by emerging evidence and FDA approval for new indications. IVIG was mostly prescribed for treatment of diseases with pathologic immune responses to foreign of self-antigens. These indications usually, require higher amounts of IVIG per admission. More studies are needed to understand whether IVIG treatments of off-label indications are effective and cost-efficient

How Can We Improve the Safe Use of Herbal Medicine and Other Natural Products? A Clinical Pharmacologist Mission

Introduction: Three major classes of natural products (NPs) for medicinal purposes or improving wellbeing are generally available in the US: conventional drugs of herbal origin, botanical drugs, and dietary supplements (DSs). Consumer consumption of DSs is growing annually. The U.S. FDA regulates conventional and botanical drugs for safety and efficacy; however, DSs are minimally regulated. Introduction: Three major classes of natural products (NPs) for medicinal purposes or improving wellbeing are generally available in the US: conventional drugs of herbal origin, botanical drugs, and dietary supplements (DSs). Consumer consumption of DSs is growing annually. The U.S. FDA regulates conventional and botanical drugs for safety and efficacy; however, DSs are minimally regulated. Expert opinion: Toxicities associated with the use of NPs, including vitamins and DSs, are mainly due to excessive use and interactions with conventional drug(s) and may represent challenges for clinicians. Conventional and botanical-based prescription drugs are rarely associated with unknown toxicities. However, DSs are minimally regulated and can produce severe adverse effects. We believe that clinical pharmacologists can have a role in developing criteria for DS safety analysis. There is also the potential for a standardized NP stewardship program(s) and the development of NP policies and practices nationally and globally
