Asthma prevalence and control among schoolchildren residing near outdoor air pollution sites.

INTRODUCTION: Outdoor air pollution (OAP) contributes to poor asthma outcomes and remains a public health concern in Pittsburgh. The purpose of this study was to determine the prevalence of childhood asthma and its rate of control among Pittsburgh schoolchildren residing near OAP sites. METHODS: Participants were recruited from schools near OAP sites. Asthma prevalence and control were assessed using a validated survey. Demographics and socioeconomic status were collected by survey, BMI was calculated, secondhand smoke (SHS) exposure was assessed by salivary cotinine levels, and OAP was assessed by mobile platform monitoring. Multivariate analysis adjusted for confounders. RESULTS: In 1202 Pittsburgh elementary school students surveyed, 50.9% were female, average age was 8.5 years (SD = 1.9), 52.2% were African American and 60.6% had public health insurance. SHS exposure was relatively high at 33.9%, 17.1% of students were obese, and 70% had exposure to particulate matter (PM2.5) greater than the World Health Organization standard of 10 µg/m3. Overall prevalence of asthma was 22.5% with PM2.5, nitric oxide (NOx), sulfur (S), and zinc (Zn) significantly related to odds of asthma. Among the 270 children previously diagnosed with asthma, 59.3% were not well controlled with PM2.5, black carbon, and silicon (Si) significantly related to odds of uncontrolled asthma. CONCLUSIONS: These results demonstrate that asthma prevalence and poor disease control are significantly elevated in Pittsburgh schoolchildren exposed to high levels of OAP. Future efforts need to focus on primary prevention of asthma by reducing exposure to OAP in at risk populations.

Pictorial versus written asthma action plans for youth: initial impact on regimen knowledge, medication adherence, symptom control, and family satisfaction.

OBJECTIVE: Asthma action plans (AAP) are recommended to guide asthma management. Written AAPs (WAAPs) are under-utilized and can be difficult to understand. Our study designed and tested a simplified pictorial AAP (PAAP). We hypothesized that better outcomes would be obtained for youth with the PAAP. METHODS: One hundred and sixty-nine (169) youth (aged 8-17; AAP-naïve) were screened for this pilot, 2-arm randomized controlled trial. Feasibility, usability and preliminary efficacy of PAAP compared to a WAAP, for improving outcomes (inhaled corticosteroid (ICS) adherence, symptom control, AAP knowledge, AAP satisfaction) were assessed quantitatively. Youth received an AAP from their physician after completing baseline measures and completed measures at three additional time points (1-, 3-, and 6-month). RESULTS: Forty-five youth were recruited (PAAP = 22; WAAP = 23). Youth AAP knowledge was higher for the PAAP group compared to the WAAP group (p = .017). ICS adherence did not differ between groups, over time, or based on prescribed dosing; however, for WAAP participants, adherence was lower with a higher daily prescription (4 puffs) relative to a lower dose (p = .006). Symptom control improved with both AAPs, but the change was not statistically significant. Lung function did not change significantly by AAP type or time, and literacy variables were not related significantly to outcomes. Youth satisfaction with AAP improved significantly for the PAAP group compared to the WAAP group (p = .03). CONCLUSIONS: Higher AAP knowledge and satisfaction among youth in the PAAP group suggests that structured education from a physician using a PAAP is beneficial. Intervention and study design insights gained will guide future research.

Evaluation of the ocular safety associated with the exhalation delivery system with fluticasone.

Background: Intranasal corticosteroids (INCS) are the cornerstone of treatment for chronic rhinosinusitis. Although INCS are generally considered safe and effective, there is a concern that chronic use may lead to ocular adverse effects. Objective: To assess ocular safety of the exhalation delivery system with fluticasone propionate (EDS-FLU) in patients with chronic rhinosinusitis with nasal polyps. Methods: Ocular safety data were collected during two randomized, double-blind, placebo controlled studies with open-label extensions. Ophthalmologists performed tonometry, slit-lamp, and visual acuity examinations to assess intraocular pressure (IOP) and the presence of cataracts. Ocular examinations were conducted before double-blind treatment, at the end of the 16-week double-blind phase, and at the end of the 8-week open-label phase. The results of pooled data from patients who received EDS-FLU 186 µg (n = 160), EDS-FLU 372 µg (n = 161), and EDS-placebo (n = 161) twice daily are reported here. Results: At the end of the double-blind phase, six patients developed elevated average IOP > 21 mm Hg: two patients (1.2%) in the EDS-placebo group, three patients (1.9%) in the EDS-FLU 186 µg group, and one patient (0.6%) in the EDS-FLU 372 µg group. In addition, 6 of 482 patients developed cataracts: 3 patients in the EDS-placebo group, 2 patients in the EDS-FLU 186 µg group, and 1 patient in the EDS-FLU 372 µg group. At the end of the open-label phase, two additional patients showed IOP > 21 mm Hg and two additional patients developed cataracts. Conclusion: No increased risk of elevated IOP was detected with EDS-FLU; the rate of cataract development was similar to EDS-placebo and to that reported with other INCS.Clinical trials NCT01622569 and NCT01624662, www.clinicaltrials.gov.

Effect of grass sublingual tablet immunotherapy is similar in children and adults: A Bayesian approach to design pediatric sublingual immunotherapy trials.

BACKGROUND: Large sample sizes are needed for sublingual immunotherapy (SLIT) trials because of inherent data variability secondary to inconsistent allergen exposure. Obtaining large sample sizes for pediatric SLIT trials is challenging, but a Bayesian approach using prior adult data can reduce the necessary sample size. OBJECTIVE: We sought to describe how a Bayesian framework using prior information from adult trials can be used to improve pediatric SLIT clinical development. METHODS: Data were compiled by using a frequentist approach (conventional clinical trial approach independent of prior data) from trials conducted during the clinical development of timothy grass SLIT-tablets. RESULTS: The treatment effect of timothy grass SLIT-tablets was considered similar between pediatric (n = 795) and adult (n = 2299) data pools, with relative total combined symptom plus medication score improvement versus placebo of 21% (95% CI, 11.0% to 30.4%) and 20% (95% CI, 14.6% to 24.4%), respectively. Phleum pratense-specific IgG4 and IgE-blocking factor increased from baseline in both children and adults treated with timothy grass SLIT-tablets. Given the reasonable assumption in similarity of treatment response between adults and children, a Bayesian approach is described to demonstrate rigorous efficacy criteria for pediatric trials incorporating information from prior adult trials and thereby reduce the sample size. CONCLUSIONS: Data support the similarity of efficacy and immunologic changes between children and adults treated with SLIT for allergic rhinoconjunctivitis. Therefore it is appropriate to use data from adult trials to design feasible trials in children, which might reduce unsafe off-label use by promoting more quickly proper labeling of approved products.

Clinical features of adolescents with chronic idiopathic or spontaneous urticaria: Review of omalizumab clinical trials.

BACKGROUND: Adults and adolescents were included in 3 phase 3 omalizumab trials in chronic idiopathic urticaria (CIU): ASTERIA I, ASTERIA II, and GLACIAL. OBJECTIVE: To describe the baseline clinical profile of adolescent patients with CIU enrolled in the omalizumab trials to add to the limited literature available on CIU in this population. METHODS: Data for patient demographics, baseline clinical disease characteristics, medical history, and previous CIU medication information (not efficacy assessments) from phase 3 omalizumab trials were pooled and descriptive statistical analyses performed for adolescent (12 to <18 years old) and adult (≥18 years old) subgroups. Inferential analysis was inappropriate, partly because of small sample size in the adolescent subgroup. RESULTS: The pooled population of 975 patients with CIU included 39 adolescents (4.0%). Demographics of adolescents and adults with CIU were similar, but compared with adults, fewer adolescents had positive Chronic Urticaria Index test results. Baseline clinical disease characteristics were also similar between the subgroups, with the number of previous CIU medications slightly lower in adolescents compared with adults. Medical history and existing conditions in adolescents tended to be more allergy than cardiovascular related, and fewer experienced angioedema compared with adults. CONCLUSION: Pooled data indicate differences in baseline demographic and clinical characteristics between adult and adolescent patient subgroups. This finding helps augment our understanding of the clinical profile of CIU in adolescents, but larger-scale studies in this population are warranted. TRIAL REGISTRATION: ClinicalTrials.gov Identifiers: NCT01287117 (ASTERIA I), NCT01292473 (ASTERIA II), and NCT01264939 (GLACIAL).

Inhaled corticosteroids: Effects on growth and bone health.

BACKGROUND: Both slowed growth in children and reduced bone mineral density (BMD) are systemic effects of corticosteroids, and there is concern about the degree to which these systemic effects affect growth and BMD. OBJECTIVE: To engage in a data-driven discussion of the effects of inhaled corticosteroids (ICSs) on growth in children and BMD. METHODS: Articles were selected based on their relevance to this review. RESULTS: Studies of ICSs in children in which growth was a secondary outcome have revealed slowed growth associated with low doses of budesonide, fluticasone propionate, and beclomethasone dipropionate. In the study of budesonide, the effect was permanent, and in the study of fluticasone propionate, the effect was long-lasting, but it is unclear whether the effect was permanent. However, the results of studies in which growth was the primary outcome were mixed. Slowed growth was detected in a study of beclomethasone dipropionate; however, slowed growth was not detected in a study of ciclesonide or flunisolide. A decrease in BMD acquisition in children was associated with high doses but not low to medium doses of ICSs. In adults, there was a dose-related effect of ICSs on BMD. Both higher daily dose and larger cumulative dose were associated with increased bone density loss. CONCLUSION: Because of the systemic effects on growth and bone health, children should be monitored for growth using stadiometry every 3 to 6 months and BMD should be monitored yearly in patients being treated with high doses of ICSs.

The tall and the short: Repainting the landscape about the growth effects of inhaled and intranasal corticosteroids.

BACKGROUND: Earlier 1-year growth studies that used older inhaled corticosteroid (ICS) formulations consistently showed that ICS, but not intranasal corticosteroids (INCS), produced a small ∼1 cm/y growth effect that appeared to be nonprogressive and noncumulative. Studies that lasted for >1 year showed that such treatment during childhood did not affect final adult height. Collectively, these studies led to the beliefs that (1) the small short-term effect on growth is unimportant, (2) there is no long-term harm, and (3) any small risk is easily outweighed by the benefit. This led to the cavalier use of ICS and INCS in children and approval of some INCS for over-the-counter sales for children as young as 2 years of age. METHODS: Literature search using Pub-Med. RESULTS: More recent studies, with improved scientific designs, have challenged and overturned the earlier beliefs. Moreover, some of the newer ICS formulations have negative, robust growth studies (designed per FDA guidance and detected no growth effect). CONCLUSIONS: This review focused on the new evidence and how it will change the way that we use ICS and INCS in children with allergy and asthma in both clinical practice and research, with a renewed focus on safety. There also are significant implications for future iterations of asthma guidelines. The goal was to identify the proper amount of new concern about ICS and INCS, not to generate undue steroid "phobia."

Sinus and adenoid inflammation in children with chronic rhinosinusitis and asthma.

BACKGROUND: Chronic rhinosinusitis (CRS) and asthma frequently coexist in children and adults. However, the precise pathophysiologic mechanism of this interaction is still poorly understood, especially in children, owing to the lack of direct measurements of mucosal inflammation in the upper airways. OBJECTIVE: To determine the pathophysiologic mechanism by analyzing the expression of a large array of inflammatory cytokines and chemokines in the sinus and adenoid tissues surgically removed from pediatric patients with CRS refractory to medical management. METHODS: Twenty-eight children 2 to 12 years old diagnosed with CRS with or without asthma and 10 controls were included in this prospective, nonrandomized study. Mucosal expression of 40 inflammatory cytokines was measured with a multiplex assay and was normalized to total tissue protein. RESULTS: Compared with children with CRS and without asthma, children with CRS and asthma had significantly higher sinus levels of tumor necrosis factor-α and adenoid levels of epidermal growth factor, eotaxin, fibroblast growth factor-2, growth-related oncogene, and platelet-derived growth factor-AA. CONCLUSION: The inflammatory response in the upper airway mucosa of children with asthma and CRS was similar, but more severe, compared with children with CRS without asthma. This observation is consistent with the hypothesis that asthma in these patients is caused or exacerbated by severe upper airway disease and supports the concept that treating sinus disease is paramount in the management of chronic asthma in children using, for the first time, direct measurements of airway inflammation in children.

The Future of Sublingual Immunotherapy in the United States.

Sublingual immunotherapy (SLIT) is a safe and effective treatment for allergic rhinitis (AR) and allergic rhinoconjunctivitis (ARC). The Food and Drug Administration (FDA) in the USA has approved three SLIT tablets for the treatment of AR and ARC in relation to pollen. Specifically, Grastek® and Oralair® are two formulations approved to treat patients suffering with AR/ARC to grass pollen, and Ragwitek™ is a formulation approved to treat patients suffering with AR/ARC to ragweed pollen. Although these approvals provide support for physicians to prescribe SLIT, barriers to prescribing SLIT still remain such as FDA approval for additional formulations, a standard dose and dosing schedule, and cost/insurance coverage. In order to further support the use of SLIT, research is currently being conducted to expand the indication for SLIT to other common comorbidities to AR/ARC. For example, allergic asthma, food allergies, and atopic dermatitis are other diseases which are being explored. The future of SLIT in the USA is unknown; however, education will be necessary for both providers and patients.

Pharmacist-led screening program for an inner-city pediatric population.

OBJECTIVES: To identify the prevalence of asthma, obesity, hypertension, and environmental tobacco smoke (ETS) exposure among youth and provide recommendations for follow-up care. METHODS: This cross-sectional study consisted of 12 health screenings for children between 5 and 17 years of age in various inner city, lower socioeconomic, and predominantly black communities throughout the city of Pittsburgh, PA. The screenings were conducted by pharmacists and student pharmacists from April 2010 to April 2012. Asthma, obesity, hypertension, and ETS screenings were offered at each event. RESULTS: A total of 144 children (50% girls, 89% black, non-Hispanic) were enrolled. Sixteen percent of the study population had a previous diagnosis of asthma; 4% were poorly controlled, and 18% were identified as having potential, undiagnosed asthma. Fifty-three percent were at an unhealthy weight (0.7% underweight, 24.3% overweight, 28.5% obese), 24% had abnormal blood pressure (12.8% prehypertension, 8.5% stage 1 hypertension, 2.8% stage 2 hypertension), and 26% had ETS exposure equivalent to that of smokers (0.7% light smokers, 17.5% smokers, and 7.7% heavy smokers). Overall, 177 specific referrals were made. The incidence of hypertension (P <0.001) and the proportion of ETS equivalent to heavy smokers increased (P = 0.019) with increased weight classification. CONCLUSION: Within this self-selected inner city, predominantly black pediatric population, there were high rates of positive screens for potential asthma, obesity, hypertension, and smoking. Additionally, the risk for high ETS exposure and hypertension increased with increasing weight. This study highlights the importance of pharmacists in disease screening and the need for alternative prevention and management strategies in disparate pediatric populations.

Diagnosis and treatment of nasal and ocular allergies: the Allergies, Immunotherapy, and RhinoconjunctivitiS (AIRS) surveys.

BACKGROUND: Allergic rhinoconjunctivitis (ARC) is managed by a number of health care professional specialties, whose practice styles may vary. OBJECTIVE: To survey patients and health care professionals about the diagnosis and treatment of ARC. METHODS: The Allergies, Immunotherapy, and RhinoconjunctivitiS (AIRS) surveys were telephone surveys of randomly selected patients and health care professionals in the United States in 2012. Participants were 2,765 people ever diagnosed as having nasal and/or ocular allergies and 500 practitioners in 7 specialties who were treating ARC. RESULTS: Adult respondents to the patient survey reported that their allergies had been diagnosed most often by physicians in family practice (46%) rather than by allergists/immunologists (17%) or otolaryngologists (11%). Children's allergies had been diagnosed most often by pediatricians (41%) and family practitioners (22%). Most respondents with conditions diagnosed by an allergist/immunologist (94.9%) or otolaryngologist (62.7%) had been given an allergy test, but the test was not given to most patients with conditions diagnosed by family practitioners (61.3%) or pediatricians (64.9%). Most patients (75.8%) were treating their allergies with over-the-counter medications, and 53.5% were taking prescription medications. Allergen immunotherapy was being used by 33% (adult) or 28% (child) patients of allergist/immunologists, 25% (adult) or 24% (child) patients of otolaryngologists, and 8% and 10% of patients of family practitioners and pediatricians, respectively. CONCLUSION: Most patients took nonprescription medications for their allergy symptoms or were treated by general practitioners, who did not use allergy testing when diagnosing ARC. Most patients seen by allergist/immunologists and otolaryngologists were evaluated with allergy tests, and most allergen immunotherapy was provided by allergy specialists.

Efficacy and safety of grass sublingual immunotherapy tablet, MK-7243: a large randomized controlled trial.

BACKGROUND: In North America, few studies have evaluated sublingual immunotherapy for allergic rhinitis with or without conjunctivitis (AR/C); pediatric data are sparse. The authors report findings from the largest published immunotherapy trial yet conducted in adults and children. OBJECTIVE: To evaluate grass sublingual immunotherapy tablet (MK-7243) treatment in subjects with AR/C. METHODS: North American subjects (5-65 years old) with grass allergy were randomized 1:1 to once-daily MK-7243 (2,800 BAU Phleum pratense) or placebo. The first dose was given at the investigator's office; subsequent doses were self-administered at home. The primary end point was total combined score (TCS; rhinoconjunctivitis daily symptom score [DSS] plus daily medication score [DMS]) over the entire grass pollen season (GPS). Key secondary end points included entire-season DSS, DMS, peak-season TCS, and rhinoconjunctivitis quality-of-life questionnaire scores. Safety outcomes included adverse events (AEs). RESULTS: One thousand five hundred one subjects were randomized (85% polysensitized, 25% had asthma). MK-7243 yielded improvements vs placebo of 23% in entire-season TCS (median difference -0.98, P < .001), 29% in peak-season TCS (median difference -1.33, P < .001), 20% in entire-season DSS (median difference -0.64, P = .001), 35% in entire-season DMS (mean difference -0.48, P < .001), and 12% in peak-season rhinoconjunctivitis quality-of-life questionnaire (median difference -0.13, P = .027). Efficacy between children and adults was similar. Most AEs were transient local application-site reactions, with no serious treatment-related AEs or anaphylactic shock. Three subjects (1 placebo, 2 MK-7243) had moderate systemic allergic reactions. CONCLUSION: MK-7243 was effective in polysensitized grass-allergic North American children and adults with AR/C in this large trial, confirming previous research.

An asthma sports camp series to identify children with possible asthma and cardiovascular risk factors.

BACKGROUND: The prevalence of asthma and obesity in children has increased over the past several years, with obesity being associated with higher rates of asthma. In response to known disparities in asthma prevalence and morbidity, along with barriers to diagnosis, assessment and education, a comprehensive asthma sports camp series was developed and implemented. OBJECTIVE: The primary objective was to evaluate the effectiveness of utilizing a sports camp model to identify children with undiagnosed and uncontrolled asthma, and to provide recommendations for follow-up care. The secondary objectives were to identify the presence of and associations between related co-morbidities and risk factors for asthma morbidity such as obesity, hypertension and exposure to tobacco smoke; and to assess asthma medication use. METHODS: Six daylong camps at an inner-city university were offered to children 5-17 years of age over a period of two years. Asthma, body mass index, blood pressure (BP) and carbon monoxide screenings were conducted at each camp. RESULTS: In this sample, 43.7% of children had previously diagnosed asthma, and 12.6% were classified as having potential, undiagnosed asthma. Of the children with previously diagnosed asthma, 76% were considered uncontrolled. Thirty-eight percent were determined to be overweight or obese and 17% had elevated BP. CONCLUSIONS: An interdisciplinary sports camp model can be used to identify children with undiagnosed and uncontrolled asthma and cardiovascular risk factors; and to provide recommendations for follow-up care.

Effect of cetirizine on symptom severity and quality of life in perennial allergic rhinitis.

The effect of cetirizine on quality of life (QOL) in subjects with perennial allergic rhinitis (PAR) has been previously evaluated using generic instruments. While generic QOL tools are used across various conditions, disease-specific instruments evaluate the impact of treatment on areas that are affected by that particular condition. This study evaluated the effect of cetirizine on symptom severity and health-related QOL, using a disease-specific instrument, in adults with PAR. This randomized, double-blind, placebo-controlled study was conducted at 15 U.S. centers outside the pollen allergy season. After a 1-week placebo run-in period, qualified subjects aged 18-65 years with PAR were randomized to once-daily cetirizine 10 mg (n = 158) or placebo (n = 163) for 4 weeks. Change from baseline in total symptom severity complex (TSSC) and overall Rhinitis Quality of Life Questionnaire (RQLQ) scores were primary efficacy end points. Cetirizine produced significantly greater improvements in mean TSSC for each treatment week (p < 0.05) and for the entire 4-week treatment period (p = 0.005) compared with placebo. After 4 weeks, cetirizine-treated subjects reported significantly greater overall improvement in RQLQ scores compared with placebo-treated subjects (p = 0.004). After 1 week, cetirizine produced significant improvements in the nasal symptoms, practical problems, and activities RQLQ domain scores compared with placebo (p < 0.05). After 4 weeks, cetirizine-treated subjects reported significant reductions in these RQLQ domain scores and in emotion domain scores compared with placebo-treated subjects (p < 0.05). Cetirizine 10 mg daily produced significant improvements in symptom severity and allergic rhinitis-related QOL compared with placebo in adults with PAR.

The Allergies, Immunotherapy, and RhinoconjunctivitiS (AIRS) survey: patients' experience with allergen immunotherapy.

Allergen immunotherapy (AIT) is used for the treatment of allergic rhinoconjunctivitis as a subcutaneous injection (subcutaneous immunotherapy [SCIT]). Extracts used for SCIT are also used off-label to formulate a liquid delivered as sublingual drops (sublingual immunotherapy [SLIT]). This study was designed to survey patients' experiences and beliefs regarding SCIT and SLIT. People who had ever been diagnosed with nasal and/or ocular allergies were identified in a 2012 telephone survey of U.S. households. Respondents were asked questions about their or their child's use of SCIT and SLIT and their beliefs about AIT. Of 2765 respondents, 46.5% had ever heard of AIT and 22.7% had ever initiated it: 20.9% with SCIT and 1.8% with SLIT (p < 0.0001). The most frequently cited reason for beginning AIT was that symptoms were unresolved with other medications (SCIT, 32.1%; SLIT, 14.0%). Some or full symptom relief was reported by 74.9% of respondents treated with SCIT and 66.0% of those treated with SLIT (p = 0.17 for SCIT versus SLIT). Approximately one-third of respondents who had ever heard of or had been treated with AIT said "don't know" when asked if immunotherapy controls allergy symptoms for years (33.6%), is a very safe treatment (29.3%), or can cure allergy symptoms (27.5%). Effective relief of allergy symptoms was cited most often as the primary benefit of SCIT (37.8%) and convenience was the primary benefit of SLIT (14%). Only one-fifth of respondents had ever been treated with AIT, largely with SCIT. More than one-half of respondents had never heard of AIT and respondents' beliefs indicated a need for educational efforts.

Ocular and nasal allergy symptom burden in America: the Allergies, Immunotherapy, and RhinoconjunctivitiS (AIRS) surveys.

Previous nationwide surveys of allergies in the United States have focused on nasal symptoms, but ocular symptoms are also relevant. This study determines the effects of ocular and nasal allergies on patients' lives. Telephone surveys of randomly selected U.S. households (the patient survey) and health care providers (provider survey) were conducted in the United States in 2012. Study participants were 2765 people ≥5 years of age who had ever been diagnosed with nasal or ocular allergies and 500 health care providers in seven specialties. Respondents to the patient survey reported a bimodal seasonal distribution of allergy symptoms, with peaks in March to May and September. Nasal congestion was the most common of the symptoms rated as "extremely bothersome" (39% of respondents), followed by red, itchy eyes (34%; p = 0.84 for difference in extreme bothersomeness of nasal and ocular symptoms). Twenty-nine percent of respondents reported that their or their child's daily life was impacted "a lot" when allergy symptoms were at their worst. Workers rated their mean productivity at 29% lower when allergy symptoms were at their worst (p < 0.001 compared with no symptoms). Providers reported that itchy eyes was the symptom causing most patients to seek medical treatment by pediatricians (73%), ophthalmologist/optometrists (72%), and nurse practitioners or physician assistants (62%), whereas nasal congestion was the symptom causing most patients to seek treatment from otolaryngologists (85%), allergist/immunologists (79%), and family medicine practitioners (64%). Ocular and nasal allergy symptoms substantially affected patients' lives and were comparable in their impact.

A critical review of the effects of inhaled corticosteroids on growth.

Inhaled corticosteroids (ICSs) are an effective therapy for the treatment of persistent asthma of all severities because they reduce symptoms, improve lung function, and reduce underlying inflammation. Although ICSs are generally safe for long- term use, there is concern among physicians and patients about potential systemic side effects, including growth inhibition in children. This continued concern of systemic side effects may negatively affect the compliance to ICS treatment. Based on the current guidance to industry from the Food and Drug Administration (FDA), some efficacy and safety studies on ICSs performed in the 1990s had limitations in their design to evaluate the effect of ICS therapy on growth as a safety end point. A review of studies performed with currently available ICSs and their level of conformance with the FDA guidance are presented in this article. The 1-year studies show a small, dose-dependent effect of most ICSs on childhood growth, with some differences across various ICS molecules and across individual children. Some ICSs at the doses studied did not affect childhood growth using rigorous study designs. Most studies did not conform completely with the FDA guidance. The data on effects of childhood ICS use on final adult height are conflicting, but one recent well-designed study showed an effect, clearly warranting additional studies.

Efficacy and safety of timothy grass allergy immunotherapy tablets in North American children and adolescents.

BACKGROUND: Allergy immunotherapy tablet (AIT) treatment might be a safe and convenient form of specific immunotherapy but it has not been investigated in North American children and adolescents. OBJECTIVE: We sought to investigate the efficacy and safety of timothy grass AIT treatment in North American children/adolescents with grass pollen-induced allergic rhinoconjunctivitis (ARC) with or without asthma. METHODS: Three hundred forty-five subjects (5-17 years old) were randomized to once-daily grass AIT treatment (2,800 bioequivalent allergen units, 75,000 standardized quality tablet, approximately 15 µg of Phl p 5) or placebo approximately 16 weeks before the 2009 grass pollen season (GPS). Treatment continued through the GPS. Daily symptoms and allergy rescue medication use were recorded. The primary end point was the total combined score (TCS) of the daily symptom score (DSS) and daily medication score (DMS) for the entire GPS. DSS, DMS, Rhinoconjunctivitis Quality of Life Questionnaire score, and Phl p 5-specific IgG4 and IgE-blocking factor levels were secondary end points. Safety was assessed through adverse events. RESULTS: Eighty-nine percent of subjects were multisensitized. TCS, DSS, DMS, and Rhinoconjunctivitis Quality of Life Questionnaire score versus placebo improved 26% (P = .001), 25% (P = .005), 81% (P = .006), and 18% (P = .04). Phl p 5-specific IgG4 and IgE-blocking factor levels were significantly higher at the peak and end of the GPS (P < .001). Treatment was well tolerated. Adverse events were generally mild and transient. Although no investigator-assessed systemic allergic reactions were reported, 1 grass AIT-treated subject experienced an event indicating a systemic reaction (lip angioedema, dysphagia, and cough). CONCLUSIONS: Use of once-daily timothy grass AIT treatment effectively treats timothy grass (cross-reactive with Festucoideae grasses) pollen-induced ARC in North American children 5 years and older. Given its convenient administration, lack of dose build-up requirement, safety profile, and efficacy, AIT treatment might become an important addition to the North American ARC treatment armamentarium.

Is This Medication Safe for My Child? How to Discuss Safety of Commonly Used Medications With Parents.

All drugs have potential side effects, but thoughtful use can maximize benefits while minimizing risks. Children should not be considered just small adults regarding drug safety because their growth and development are discordant with their ability to sense and self-report drug side effects. Detecting side effects requires vigilance and education from prescribers to parents, who are tasked with monitoring their child over time. A drug's safety profile is published in the package label after pivotal trials are conducted in relatively small and sometimes narrow segments of the population during the U.S. Food and Drug Administration approval process. Drug safety profiles can change as data from postmarketing reports and long-term monitoring during phase IV trials emerge. As such, prescribers are obligated to maintain current understanding of any changes to drug labels. Discussing potential side effects, monitoring, and when to report concerns can be a time-consuming process during patient encounters. This review offers current information regarding potential side effects of some of the most commonly used medications for allergic conditions, asthma, and atopic dermatitis. This information and discussion will hopefully assist clinicians in their conversations with parents, including advice surrounding prescribing medication to minimize adverse effects, parental monitoring, and documentation.

Serial Convalescent Plasma Infusions for the Initial COVID-19 Infections in the Appalachian Region of West Virginia.

Purpose: The rapid spread of SARS-CoV-2, the virus that is responsible for causing COVID-19, has presented the medical community with another example of when convalescent plasma (CP) is still used today. The ability to standardize CP at the onset of a pandemic is unlikely to exist in a reliable and uniformly reproducible way. We hypothesized that CP of unknown strength given in a serial manner will promote health and reduce mortality in those inflicted with COVID-19. Methods: Participants were given up to 8 CP-units depending on their condition upon entry into the study and their response. Results: 102 out of 117 participants were given CP. The earlier a participant received CP corelated with survival (p = 0.0004). The number of CP-units given, throughout all the clinical severities, was not significant with outcomes, p = 0.3947. A higher number of CP-units given to the severe/critical participants (without biological immunosuppressants or restrictive lung disease) did correlate with survival p = 0.0116 (2.8 vs. 2 units). Lower platelets on admission corelated with mortality. Platelet levels increase correlated with CP infusions p < 0.0001. Conclusion: This study supports the serial use of CP of unknown strength based on clinical response for those infected with COVID-19. The use of 3-4 units of CP was found to be statistically significant for survival for severe and critical participants without restrictive lung disease and chronic biological immunosuppression. Increased platelet levels after CP infusions supports that CP is promoting overall health regardless of outcomes.
