Antibiotic Use in Patients With ß-Lactam Allergies and Pneumonia: Impact of an Antibiotic Side Chain-Based Cross-Reactivity Chart Combined With Enhanced Allergy Assessment.

BACKGROUND: ß-lactam antibiotics with dissimilar R-group side chains are associated with low cross-reactivity. Despite this, patients with ß-lactam allergies are often treated with non-ß-lactam alternative antibiotics. An institutional ß-lactam side chain-based cross-reactivity chart was developed and implemented to guide in antibiotic selection for patients with ß-lactam allergies. METHODS: This single-center, retrospective cohort study analyzed the impact of the implementation of the cross-reactivity chart for patients with pneumonia. Study time periods were defined as January 2013 to October 2014 prior to implementation of the chart (historical cohort) and January 2017 to October 2018 (intervention cohort) following implementation. The primary outcome was the incidence of ß-lactam utilization between time periods. Propensity-weighted scoring and interrupted time-series analyses compared outcomes. RESULTS: A total of 341 and 623 patient encounters were included in the historical and intervention cohorts, respectively. There was a significantly greater use of ß-lactams in the intervention cohort (70.4% vs 89.3%; P < .001) and decreased use of alternative therapy (58.1% vs 36%; P < .001). There was no difference in overall allergic reactions between cohorts (2.4% vs 1.6%; P = .738) or in reactions caused by ß-lactams (1.3% vs 0.9%; P = .703). Inpatient mortality increased (0% vs 6.4%; P < .001); however, no deaths were due to allergic reactions. Healthcare facility-onset Clostridioides difficile infections decreased between cohorts (1.2% vs 0.2%; P = .032). CONCLUSIONS: Implementation of a ß-lactam side chain-based cross-reactivity chart and enhanced allergy assessment was associated with increased use of ß-lactams in patients with pneumonia without increasing allergic reactions.

Impact of an Antibiotic Side-Chain-Based Cross-reactivity Chart Combined With Enhanced Allergy Assessment Processes for Surgical Prophylaxis Antimicrobials in Patients With ß-Lactam Allergies.

BACKGROUND: ß-Lactam antibiotics are first-line therapy for perioperative prophylaxis; however, patient-reported allergies often lead to increased prescribing of alternative antibiotics that may increase the incidence of surgical site infections. The R-group side chain of the ß-lactam ring is responsible for allergic cross-reactivity and experts recommend the use of ß-lactams that are structurally dissimilar. METHODS: An internally developed, antibiotic side-chain-based cross-reactivity chart was developed and implemented alongside enhanced allergy assessment processes. This single-center, quasi-experimental study analyzed antibiotic prescribing in all adult patients with a documented ß-lactam allergy undergoing an inpatient surgical procedure between quartile (Q) 1 (2012)-Q3 (2014) (historical group) and Q3 (2016)-Q3 (2018) (intervention group). Propensity-weighted scoring analyses compared categorical and continuous outcomes. Interrupted time-series analysis further analyzed key outcomes. RESULTS: A total of 1119 and 1089 patients were included in the historical and intervention cohorts, respectively. There was a significant difference in patients receiving a ß-lactam alternative antibiotic between cohorts (84.9% vs 15.1%; P < .001). There was a decrease in 30-day readmissions in the intervention cohort (7.9% vs 6.3%; P = .035); however, there was no difference in the incidence of SSIs in patients readmitted (14.8% vs 13%; P = .765). No significant differences were observed in allergic reactions (0.5% vs 0.3%; P = .323), surgical site infections, in-hospital and 30-day mortality, healthcare facility-onset Clostridiodes difficile infection, acute kidney injury, or hospital costs. CONCLUSIONS: Implementation of an antibiotic cross-reactivity chart combined with enhanced allergy assessment processes significantly improved the prescribing of ß-lactam antibiotics for surgical prophylaxis.

Camp Leadership Perspectives on Food Allergy-Related Anaphylaxis Events and Training for Camp Staff: A National Survey of Summer Camps.

BACKGROUND: Training of camp staff to recognize and treat anaphylaxis is recommended because food allergies are prevalent among summer campers. The frequency of food allergy anaphylaxis events and the extent of anaphylaxis training for camp staff are unknown. OBJECTIVE: To estimate the frequency of food-allergic reactions in camps across the United States and to assess the state of food allergy anaphylaxis training for camp staff. METHODS: We partnered with CampDoc.com to send a 20-question survey in February 2016 to camp leadership representing 528 camps. Questions addressed demographic characteristics, food allergy policies, training, medication availability, anaphylaxis events, and confidence in staff to recognize and treat anaphylaxis. RESULTS: A total of 559 responses were received, representing 258 camps. The majority surveyed (n = 529 [94.6%]) reported food-allergic children attending their camps. Only 47.6% (n = 266) respondents reported requiring individualized emergency action plans as required for camper attendance. Anaphylaxis treated with epinephrine was reported by 24% (n = 134) of leadership within the previous 2 years at their camp. These respondents were more likely to have a training session for staff (odds ratio, 2.46; 95% CI, 1.4-4.3). A total of 63.3% (n = 354) reported training session presence. However, 15.6% (n = 87) of leadership were unsatisfied with training materials and one-third were not confident in staff to manage anaphylaxis. CONCLUSIONS: Appropriate policies to manage food anaphylaxis events and anaphylaxis management training were missing in a substantial proportion of camps. Camp-tailored food allergy training is needed given the number of camps reporting food allergy reactions requiring epinephrine.

Improving Patient-Provider Communication and Therapeutic Practice Through Better Integration of Electronic Health Records in the Exam Room: A Pilot Study.

BACKGROUND: The rapid proliferation of electronic health records (EHRs) in clinics has had mixed impact on patient-centered communication, yet few evaluated interventions exist to train practicing providers in communication practices. AIMS: We extended the evidence-based Physician Asthma Care Education (PACE) program with EHR-specific communication strategies, and tested whether training providers with the extended program (EHR-PACE) would improve provider and patient perceptions of provider communication skills and asthma outcomes of patients. METHOD: A pilot randomized design was used to compare EHR-PACE with usual care. Participants were providers ( n = 18) and their adult patients with persistent asthma ( n = 126). Outcomes were assessed at baseline and 3- and 6-month postintervention, including patient perception of their provider's communication skills and provider confidence in using EHRs during clinical encounters. RESULTS: Compared with the control group, providers who completed the EHR-PACE program reported significant improvements at 3-month follow-up in their confidence with asthma counseling practices (estimate 0.90, standard error [ SE] 0.4); p < .05) and EHR-specific communication practices (estimate 2.3, SE 0.8; p < .01), and at 6-month follow-up, a significant decrease in perception that the computer interferes with the patient-provider relationship (estimate -1.0, SE 0.3; p < .01). No significant changes were observed in patient asthma outcomes or their perception of their provider's communication skills. DISCUSSION: Training providers with skills to accommodate EHR use in the exam room increases provider confidence and their perceived skills in maintaining patient-centered communications in the short term. CONCLUSION: Evidence-supported training initiatives that can increase capacity of busy providers to manage increased computing demands shows promise. More research is needed to fully evaluate EHR-PACE on patients' health status and their perceptions of their provider's care through a large-scale trial.

Food Allergy Trends and Epinephrine Autoinjector Presence in Summer Camps.

BACKGROUND: Pediatric campers with food allergies are at greater risk for exposure and anaphylaxis. A diagnosis of asthma increases risk for anaphylaxis. Epidemiological investigations of food-allergic children at high risk for allergic reactions requiring intervention in camp settings are lacking. OBJECTIVE: The objectives of this study were to estimate the prevalence of food allergies among otherwise healthy campers in summer camps throughout the United States and Canada, and to assess asthma comorbidity and determine rates of epinephrine autoinjector prescriptions present in this population. METHODS: We partnered with CampDoc.com, a web-based camp electronic health record system. Deidentified data were abstracted from 170 camps representing 122,424 campers. Only food allergies with a parental report of symptoms requiring intervention or with a camp prescription for an epinephrine autoinjector were included, whereas gluten, lactose intolerance, and food dyes were excluded. Asthma status and epinephrine presence on the camp medication list were assessed. RESULTS: Overall, 2.5% of campers (n = 3055) had documented food allergies. Of these campers, 22% had multiple food allergies. Median age was 11 years; 52% were female. Nuts (81%), seafood (17.4%), egg (8.5%), fruit (8.1%), and seeds (7.2%) were the top 5 food allergies reported. Of food-allergic campers, 44.3% had concurrent asthma and 34.7% of those campers were taking multiple asthma medications. Less than half (39.7%) of food-allergic children brought an epinephrine autoinjector to the camp. CONCLUSIONS: Life-saving epinephrine is not necessarily available for food-allergic children in camp settings. A substantial proportion of food-allergic campers are at higher risk for anaphylaxis based on concurrent asthma status.

The extent and patterns of multiple chronic conditions in low-income children.

BACKGROUND AND OBJECTIVES: Little is known about the magnitude of multiple chronic conditions (MCC) in children. This study describes the prevalence of and patterns of comorbidities in children receiving Medicaid assistance. METHODS: Diagnoses from 5 years of Medicaid claims data were reviewed and identified 128,044 children with chronic conditions. The relationship between comorbidities and significant urgent health care events was analyzed using logistic regression modeling. RESULTS: More than 15,000 children (12%) had claims for more than 1 condition. The most frequent combination was asthma and allergic rhinitis. Significant health care events ranged from 18% to 51% in children, and the odds of having a significant event increased with each additional condition. Those with ≥4 conditions had 4.5 times the odds of a significant event compared with those with 1 condition (P < .0001). CONCLUSION: MCC are prevalent in low-income children and are associated with greater risk for urgent health care use.

Asthma outcomes in children and adolescents with multiple morbidities: Findings from the National Health Interview Survey.

BACKGROUND: More Americans are managing multiple chronic conditions (MCCs), and trends are particularly alarming in youth. OBJECTIVE: The purpose of this study was to examine the prevalence and distribution of 9 chronic conditions in children and adolescents with and without asthma, and adverse asthma outcomes associated with having MCCs. METHODS: Cross-sectional interview data from the National Health Interview Survey were analyzed (N = 66,790) between 2007 and 2012 in youth 0 to 17 years of age. Bivariate analysis methods and multivariate generalized linear regression were used to examine associations. RESULTS: Five percent of children with asthma had 1 or more coexisting health conditions. The prevalence of 1 or more comorbidities was greater among those with asthma than those without (5.07% [95% CI: 4.5-5.6] vs. 2.73% [95% CI: 2.6-2.9]). Those with asthma were twice as likely to have co-occurring hypertension (prevalence ratio [PR] = 2.2 [95% CI: 1.5-3.2]) and arthritis (PR = 2.7 [95% CI: 1.8-4.0]) compared with those without asthma. Every additional chronic condition with asthma was associated with a greater likelihood of an asthma attack (PR = 1.1 [95% CI: 1.0-1.2]), all-cause emergency department visits (PR = 1.3 [95% CI: 1.1-1.5]), and missed school days (PR = 2.3 [95% CI: 1.7-3.2]). CONCLUSIONS: Children and adolescents with asthma in the US who suffer from MCCs have increased asthma symptoms, missed school days, and all-cause emergency department visits. Further research on optimal management strategies for this group is needed.

Addressing food allergy issues within child care centers.

The prevalence of food allergies in the pediatric population has risen significantly in the past decade. School districts and advocacy groups have made progress in developing systematic approaches to address pediatric food allergies; however, the widespread variance in child care settings, organization, and staff training still presents unique challenges. Addressing these obstacles requires multiple approaches to policy and guideline formulation and dissemination. This review discusses current issues in food allergy prevention and education in child care settings and offers potential solutions.

The relationship of season of birth to asthma and allergy in urban African American children from 10 to 13 years of age.

OBJECTIVES: To assess the relationship between season of birth and presence of asthma and allergy in preteen, low-income, African American children. METHODS: The study consisted of a self-administered survey followed by telephone interviews of parents of children attending 19 middle schools in Detroit, Michigan. Out of 4194 children, 1292 were identified with asthma and 962 parents of these children provided informed consent and took part in telephone interviews. RESULTS: No statistically significant relationships were observed between season of birth and diagnosis of asthma (p > .05) or with diagnosis adjusting for income, age, gender, parent's education, or parent being a smoker (p > .05). No statistically significant association was evident between season of birth and presence of allergy (p > .05) or with allergy adjusting for the above variables (p > .05). CONCLUSIONS: Identifying children vulnerable to problems with asthma and allergy, especially in populations exhibiting high prevalence of the conditions and significant disparities in outcomes, requires use of all possible means. Season of birth does not appear to be a useful indicator in identification of such children. The findings from this study do not support the proposition that season of birth, associated with early exposure to viruses as evident in the winter and to seasonal allergens, contributes to more asthma and/or allergy.

Peanut-allergic subjects and their peanut-tolerant siblings have large differences in peanut-specific IgG that are independent of HLA class II.

We enrolled 53 peanut-allergic subjects and 64 peanut-tolerant full siblings, measured peanut-specific IgG and IgE, determined HLA class II at high resolution, and analyzed DRB1 alleles by supertypes. Peanut-specific IgG and IgE were elevated in the peanut-allergic subjects (p<0.0001) but did not stratify with HLA alleles, haplotypes, or supertypes. There were no significant differences in HLA class II between the peanut-allergic and peanut-tolerant siblings but there was an increased frequency of DRB1*0803 in both sets of siblings compared to unrelated controls (p(c)=4.5×10⁻9). Furthermore, we identified 14 sibling pairs in which the peanut-allergic and the peanut-tolerant siblings have identical HLA class II and again found an elevation of anti-peanut IgG in the peanut-allergic subjects (p<0.0001). In conclusion, although DRB1*0803 may identify a subset of families with increased risk of peanut allergy, differences in peanut-specific immunoglobulin production between peanut-allergic subjects and their peanut-tolerant siblings are independent of HLA class II.

A developmental, community, and psychosocial approach to food allergies in children.

Recent estimates show that food allergies affect a substantial proportion of children in the United States and appear to have increased in prevalence. At present, management of food allergies consists of strict avoidance of the responsible allergen and an appropriate response should a reaction occur. Creating safe environments for the growing number of children with food allergies requires a partnership between affected families and members of the caregiving and educational communities. This article reviews issues affecting children with food allergies at different stages of psychosocial development and discusses strategies that can be implemented to promote food safety within child care and school environments as well as in the community. It also presents an overview of policy developments at the state and national level that have implications for children with food allergies.

A novel mutation in NFKBIA/IKBA results in a degradation-resistant N-truncated protein and is associated with ectodermal dysplasia with immunodeficiency.

Alterations in nuclear factor kappa B (NF-kappaB) essential modulator (NEMO; HUGO-approved symbol IKBKG) underlie most cases of ectodermal dysplasia with immune deficiency (EDI), a human disorder characterized by anhidrosis with diminished immunity. EDI has also been associated with a single heterozygous mutation at position Ser32 of the NF-kappaB inhibitor IkappaBalpha, one of two phosphorylation sites that are essential for targeting IkappaBalpha for proteasomal degradation and hence for activation of NF-kappaB. We report a novel heterozygous nonsense mutation in the IKBA (HUGO-approved symbol, NFKBIA) gene of a 1-year-old male child with EDI that introduces a premature termination codon at position Glu14. An in-frame methionine downstream of the nonsense mutation allows for reinitiation of translation. The resulting N-terminally truncated protein lacks both serine phosphorylation sites and inhibits NF-kappaB signaling by functioning as a dominant negative on NF-kappaB activity in lymphocytes and monocytes. These findings support the scanning model for translation initiation in eukaryotes and confirm the critical role of the NF-kappaB in the human immune response.

Managing children with food allergies in childcare and school.

In the past decade the rise in life-threatening allergic reactions to foods in young children has necessitated increased interaction among personnel in the psychosocial, medical, and educational arenas regarding the multifaceted aspects of this concerning problem. Schools and childcare facilities are vital venues for the continued growth and development of children outside the home. However, these facilities offer unique challenges to caring for the food-allergic child, requiring that the medical, educational, and caretaking communities work in unison to provide the safest environment for all children. Despite the potential obstacles, these settings offer a tremendous opportunity for the development and implementation of strategies to provide for proper identification of children at risk, to increase awareness and prevention, and for the provision of optimal treatment of food-related anaphylactic reactions occurring outside the home.
