Provision of COVID-19 Convalescent Plasma in a Resource-Constrained State.

BACKGROUND: Arkansas is a rural state of 3 million people. It is ranked fifth for poverty nationally. The first case of coronavirus disease 2019 (COVID-19) in Arkansas occurred on 11 March 2020. Since then, approximately 8% of all Arkansans have tested positive. Given the resource limitations of Arkansas, COVID-19 convalescent plasma (CCP) was explored as a potentially lifesaving, therapeutic option. Therefore, the Arkansas Initiative for Convalescent Plasma was developed to ensure that every Arkansan has access to this therapy. STUDY DESIGN AND METHOD: This brief report describes the statewide collaborative response from hospitals, blood collectors, and the Arkansas Department of Health (ADH) to ensure that CCP was available in a resource-limited state. RESULTS: Early contact tracing by ADH identified individuals who had come into contact with "patient zero" in early March. Within the first week, 32 patients tested positive for COVID-19. The first set of CCP collections occurred on 9 April 2020. Donors had to be triaged carefully in the initial period, as many had recently resolved their symptoms. From our first collections, with appropriate resource and inventory management, we collected sufficient CCP to provide the requested number of units for every patient treated with CCP in Arkansas. CONCLUSIONS: The Arkansas Initiative, a statewide effort to ensure CCP for every patient in a resource-limited state, required careful coordination among key players. Collaboration and resource management was crucial to meet the demand of CCP products and potentially save lives.

Sustained unresponsiveness to peanut in subjects who have completed peanut oral immunotherapy.

BACKGROUND: Although peanut oral immunotherapy (OIT) has been conclusively shown to cause desensitization, it is currently unknown whether clinical protection persists after stopping therapy. OBJECTIVE: Our primary objective was to determine whether peanut OIT can induce sustained unresponsiveness after withdrawal of OIT. METHODS: We conducted a pilot clinical trial of peanut OIT at 2 US centers. Subjects age 1 to 16 years were recruited and treated for up to 5 years with peanut OIT. The protocol was modified over time to permit dose increases to a maximum of 4000 mg/d peanut protein. Blood was collected at multiple time points. Clinical end points were measured with 5000-mg double-blinded, placebo-controlled food challenges once specific criteria were met. RESULTS: Of the 39 subjects originally enrolled, 24 completed the protocol and had evaluable outcomes. Twelve (50%) of 24 successfully passed a challenge 1 month after stopping OIT and achieved sustained unresponsiveness. Peanut was added to the diet. At baseline and the time of challenge, such subjects had smaller skin test results, as well as lower IgE levels specific for peanut, Ara h 1, and Ara h 2 and lower ratios of peanut-specific IgE/total IgE compared with subjects not passing. There were no differences in peanut IgG4 levels or functional activity at the end of the study. CONCLUSIONS: This is the first demonstration of sustained unresponsiveness after peanut OIT, occurring in half of subjects treated for up to 5 years. OIT favorably modified the peanut-specific immune response in all subjects completing the protocol. Smaller skin test results and lower allergen-specific IgE levels were predictive of successful outcome.

Developing a food allergy curriculum for parents.

BACKGROUND: Food allergy (FA) is potentially severe and requires intensive education to master allergen avoidance and emergency care. There is evidence suggesting the need for a comprehensive curriculum for food allergic families. METHODS: This paper describes the results of focus groups conducted to guide the development of a curriculum for parents of food allergic children. The focus groups were conducted using standard methodology with experienced parents of food allergic children. RESULTS: Participants were parents (n = 36) with experience managing FA recruited from allergy clinics at two academic centers. Topics identified by parents as key for successful management included as expected: (i) early signs/symptoms, (ii) 'cross-contamination', (iii) label-reading, (iv) self-injectable epinephrine; and (v) becoming a teacher and advocate. Participants also recommended developing a 'one page-road map' to the information, and to provide the information early and be timed according to developmental stages/needs. Suggested first points for curriculum dissemination were emergency rooms, obstetrician and pediatrician offices. Participants also recommended targeting pediatricians, emergency physicians, school personnel, and the community-at-large in educational efforts. Parents often sought FA information from non-medical sources such as the Internet and support groups. These resources were also accessed to find ways to cope with stress. Paradoxically, difficulties gaining access to resources and uncertainty regarding reliability of the information added to the stress experience. DISCUSSION: Based on reports from experienced parents of food allergic children, newly diagnosed parents could benefit from a comprehensive FA management curriculum. Improving access to clear and concise educational materials would likely reduce stress/anxiety and improve quality of life.

Food allergy education for school nurses: a needs assessment survey by the consortium of food allergy research.

Food allergy is increasing in school-age children. School nurses are a primary health care resource for children with food allergy and must be prepared to manage allergen avoidance and respond in the event of an allergic reaction. An anonymous survey was administered to school nurses attending their association meetings to determine their educational needs regarding children with food allergy. With 199 school nurses responding, their self-reported proficiency for critical areas of food allergy knowledge and management varied, with weaknesses identified particularly for emergency plan development, staff education, delegation, developing guidelines for banning foods and planning school trips. Nurses reported a high interest in obtaining educational materials in these areas and prefer video and Internet resources that could be promoted through professional organizations.
