Development of a community pharmacy-based intervention for patients with uncontrolled asthma.

Background: Achieving asthma control is often difficult, despite the availability of effective medications. Because of their expertise, regular contact with patients, and accessibility, community pharmacists can play an important role in helping patients manage uncontrolled asthma. Objective: To develop a community pharmacy-based intervention for improving asthma control in patients with uncontrolled moderate to severe asthma. Methods: A qualitative study involving two focus groups with six and five community pharmacists, respectively, five individual interviews with community pharmacists, and three individual interviews with asthma patients was conducted using semi-structured interview guides. Focus groups aimed to develop the first prototype of the intervention and the topics included criteria to identify patients with uncontrolled asthma, content of the intervention to manage uncontrolled asthma, and potential logistical issues. Interviews were subsequently conducted with individual pharmacists and asthma patients to evaluate the prototype and finalize the intervention. The interviews and focus group transcripts were analyzed thematically, using an iterative process. Results: In focus groups and interviews, the pharmacists discussed how they screen patients with uncontrolled asthma using prescriptions refills, their needs for a convenient tool to assess asthma control, the necessity to identify causes of uncontrolled asthma to guide asthma management strategies, and the importance of patient follow-up. During interviews, patients shared their interest for the commitment of pharmacists to managing asthma. The final intervention consists of structured face-to-face counselling sessions at community pharmacies, with six steps: screening of patients with potential uncontrolled moderate to severe asthma, assessment of asthma control, identification of the causes of uncontrolled asthma, strategies for controlling asthma, an optional follow-up at the next prescription refill, and a follow-up 3 months after the initial intervention. Conclusions: The patients and community pharmacists reached consensus on the intervention's key elements and provided support for implementing the intervention in community pharmacies.

Successful management of recurrent allergic bronchopulmonary aspergillosis after changing from mepolizumab to dupilumab: A case report.

An 81-year-old woman presented to our hospital due to an abnormal shadow on a chest X-ray and a 4-week-old persistent cough. Laboratory examination revealed increased serum eosinophils and immunoglobulin E. The Asthma Control Test (ACT) score and forced expiratory volume in 1 sec indicated airway obstruction. Chest computed tomography (CT) revealed mucoid impaction in the dilated left-lingular lobar bronchus. She was diagnosed with bronchial asthma and treated with a high-dose inhaled corticosteroid/long-acting ß2 agonist. Two months later, her mucoid impaction in the CT image worsened; moreover, bronchoscopy revealed the white mucus plug with Charcot-Leyden crystals and filamentous fungi. The patient was diagnosed with Allergic bronchopulmonary aspergillosis (ABPA) and treatment with 30 mg/day prednisolone was started. Both the blood eosinophil count and the chest image improved almost substantially, and the steroid was discontinued after a year. Sixteen months after cessation of prednisolone treatment, peripheral eosinophilia and mucoid impaction in the left B3b recurred. For the treatment of bronchial asthma and recurrent ABPA, administration of mepolizumab was initiated. Subsequently, although her peripheral eosinophils count decreased, chest CT showed expansion of the mucoid impaction and IgE increased despite mepolizumab treatment. Alternative subcutaneous injection therapy with dupilumab improved chest image, serum IgE level, and her ACT score. After changing from mepolizumab to dupilumab, her ABPA, asthma, and pulmonary function improved remarkably. This case illustrates the potential utility of dupilumab for ABPA without re-administration of oral prednisolone. Additional research is needed to identify an effective therapy for ABPA with asthma.

Early responders within seven days of dupilumab treatment for severe asthma evaluated by patient-reported outcome: a pilot study.

BACKGROUND: The management of severe asthma-associated symptoms is essential since they are distressing to the affected patients, and also greatly impair their quality of life. Dupilumab, a monoclonal antibody, blocks interleukin (IL)-4 and IL-13 signaling, both of which are crucial in acquired and innate immunity pathways through fast signal transduction, leading to an early response to treatment. Although rapid improvement within 1-3 days after dupilumab treatment was observed in moderate-to-severe atopic dermatitis, an early response within 7 days of dupilumab treatment in severe asthma has not been reported. METHODS: Twelve consecutive patients with severe asthma who were newly treated with dupilumab between July 2019 and April 2020 were retrospectively investigated. We evaluated the early response (within 7 days) of patients with severe asthma receiving dupilumab therapy. Asthma control test (ACT) and the daily ACT, which was modified from the ACT to evaluate daily symptoms associated with asthma, were adopted as patient-reported outcomes (PROs) at week 8 and within 7 days, respectively. Patients were stratified into early responders (7 days), late responders (week 8), and non-responders without significant improvement in PROs. Descriptive statistics were adopted due to the limited number of patients. RESULTS: Four of these 12 patients were early responders, with the following baseline characteristics: body mass index, <25 kg/m2; without depression; baseline forced expiratory volume in 1 second, <1.50 L; and more than one exacerbation in 1 year. On the other hand, five were late responders, and 44.4% of the nine responders were early responders. The higher the eosinophilic count and/or FeNO did not show any relationship between the early responder and nonresponder. CONCLUSIONS: The effect of dupilumab on severe asthma in patients with atopic features could be started earlier than 2 weeks, similar to atopic dermatitis. Daily ACT may be useful in monitoring the early efficacy of dupilumab in treating severe asthma.

Economic impact of mepolizumab in uncontrolled severe eosinophilic asthma, in real life.

BACKGROUND AND AIMS: Severe asthma is burdened by frequent exacerbations and use of oral corticosteroids (OCS) which worsen patients' health and increase healthcare spending. Aim of this study was to assess the clinical and economic effect of adding mepolizumab (MEP) for the treatment of these patients. METHODS: Patients >18 years old, referred to 8 asthma clinics, starting MEP between May 2017 and December 2018, were enrolled and followed-up for 12 months. Information in the 12 months before mepolizumab were collected retrospectively. The evaluation parameters included: OCS use, number of exacerbations/hospitalizations, concomitant therapies, comorbidity, and annual number of working days lost due to the disease. The primary objective was to compare the annual total cost per patient pre- and post-MEP. Secondary outcomes included rates of exacerbations and number of OCS-dependent patients. RESULTS: 106 patients were enrolled in the study: 46 male, median age 58 years. Mean annual cost pre- and post-MEP (cost of biologic excluded) was €3996 and €1,527, respectively. Total savings due to MEP resulted in €2469 (95%CI 1945-2993), 62% due to exacerbations reduction and 33% due to productivity increase. Such savings could fund about 22% of the total cost of MEP for one year. The introduction of MEP induced a clinical benefit by reducing both OCS-dependent patients (OR = 0.12, 95%CI 0.06-0.23) and exacerbation rate (RR = 0.19, 95%CI 0.15-0.24). CONCLUSIONS: Patients with severe eosinophilic asthma experienced a clinical benefit in asthma control adding MEP to standard therapy. Biologic therapy can be, partially, funded by the savings produced by patients' improvement.

Real-life effectiveness of mepolizumab in patients with severe refractory eosinophilic asthma and multiple comorbidities.

BACKGROUND: Data on mepolizumab in patients with severe eosinophilic asthma (EA) and comorbidities are needed to assess whether randomized controlled trial results are applicable in the real world. OBJECTIVE: To evaluate real-life effectiveness and the presence/absence of predictors of treatment response in patients with one or more comorbidities (nasal polyps, allergic rhinitis, gastro-esophageal reflux disease, nonallergic rhinitis with eosinophilia syndrome, obesity, bronchiectasis) who received mepolizumab (MEPO) for the treatment of severe EA. METHODS: We performed a single-center retrospective study in patients with severe asthma and presence of comorbidities treated with mepolizumab at the respiratory outpatient clinic, Policlinico-Vittorio Emanuele, Catania, Italy. Health records of 31 severe asthmatic patients were retrieved and analyzed. Asthma control test (ACT) score, blood eosinophil count, forced expiratory volume in 1 s (FEV1), FEV1% of predicted and FEV1/FVC (Forced Vital Capacity) ratio, oral corticosteroid (OCS) dosage, and exacerbations were recorded at baseline (T0), after 3 (T1), 6 (T3), 9 (T6), and 12 months (T12). Clinical response was defined when 3 of these 4 criteria were fulfilled: i) 30% exacerbation decrease; ii) 80% blood eosinophilia reduction; iii) 3 point ACT increase; iv) FEV1 increase ≥200 mL. RESULTS: 83.87% of patients were classified as responsive to MEPO treatment. Substantial depletion of the blood eosinophils (>80%) was found in 87.1% of patients, FEV1 > 200 mL was seen in 54.84% of patients, a 3-point ACT improvement from baseline was recorded in 80.65% 25 of patients and a 30% reduction of exacerbations rates was seen in 96.77% of patients. Moreover, the majority 38.71% of patients met 3/4 parameters after 12 months. Neither the comorbidities nor other characteristics (sex, BMI, age, smoking) influenced treatment response. CONCLUSIONS: MEPO in patients with severe EA is effective regardless of the presence of comorbidities.

Skin prick reactivity among asthmatics in East Africa.

BACKGROUND: The burden of asthma in Africa is high, and yet the disease is not universally prioritised. Data on allergic asthma and its impact on asthma morbidity are limited in Africa. Our aim was to describe the distribution of skin prick positivity among asthmatics in Eastern Africa. METHODS: From August 2016 to May 2018, 1671 asthmatic patients were enrolled from Uganda, Kenya, and Ethiopia as part of the African Severe Asthma Program clinical study. Skin prick testing was performed at baseline using a panel of 12 allergens, and factors associated with skin prick reactivity determined. RESULTS: Of the 1, 671 patients recruited, 71% were female with a median age of 40 years, 93.6% were aged >15 years and the patterns of asthma symptom frequency was intermittent in 2.9%, mild persistent in 19.9%, moderate persistent in 42.6% and severe persistent in 34.6% at baseline. Self-reported triggers, were dust (92%), cold weather (89%), upper respiratory infections (84%), strong smells (79%) and exposure to tobacco (78%). The majority (90%) of the participants had at least 1 positive allergen reaction, with 0.9% participants reacting to all the 12 allergens. Participants commonly reacted to house dust mites (66%), Blomia tropicalis (62%), and the German cockroach (52%). Patients sensitized to more allergens (>2) had significantly reduced lung function (FEV ≤ 80%; p = 0.001) and were more likely to visit the emergency department due to asthma (p = 0.012). There was no significant relationship between number of allergens and measures of asthma control, quality of life, and other clinical outcomes. Only the country of origin was independently associated with atopy among African asthmatics. CONCLUSION: There is a high prevalence of skin prick positivity among East African patients with asthma, with the commonest allergen being house dust mite. Skin reactivity did not correlate well with asthma severity and poor asthma control. The relation between atopy, measured through skin prick testing, and measures of asthma control among asthma patients in Eastern Africa is unclear and needs further study. TRIAL REGISTRATION: The ASAP study was registered prospectively. ClinicalTrials.gov Identifier: NCT03065920; Registration date: February 28, 2017; Last verified: February 28, 2017.

Eosinophils depletion therapy for severe asthma management following favorable response to mepolizumab.

We described three severe asthmatics whose asthma symptoms were rapidly improved by benralizumab following favorable response to mepolizumab. Benralizumab-induced eosinophil depletion contributed to clinical improvement of severe asthma after mepolizumab-induced eosinophil reduction; thus, prior favorable responses to mepolizumab may predict benralizumab efficacy.

Effects of a structured educational intervention in moderate-to-severe elderly asthmatic subjects.

BACKGROUND: Adherence to inhaled drugs is linked to patients' satisfaction with their device, and an incorrect use can negatively affect the outcomes of asthma treatment. We speculated that this is particularly true in elderly asthmatic subjects. AIM: We performed a national pre-post interventional multicentre study, enrolling moderate-to-severe asthmatic subjects aged ≥65 â€‹years treated with fixed inhaled combination drugs by dry powder inhaler (DPI) or pressurized metered dose inhaler (pMDI). Adherence and critical errors were evaluated by means of validated questionnaires at first visit (V1) and after 3-6 months (V2). At V1, subjects underwent intensive training on the correct use of their device by physical demonstration. RESULTS: A total of 411 asthmatics (F/M: 238/173, mean age±SD: 72 â€‹± â€‹5 â€‹years) participated to the study. At V1, 50% of the study subjects showed an Asthma Control Test (ACT) score ≤19 despite GINA step 3 and 4 treatment, and 40% had experienced at least one severe asthma exacerbation in the previous year. Poor adherence to treatment was recorded in 43% of subjects, and at least one error in using the device was registered in 56% of subjects. At V2, available for 318 patients, both the percentage of individuals with poor adherence and with at least one critical error significantly decreased (from 46% to 25%, and from 49% to 25%, respectively; p â€‹< â€‹0.001 for both comparisons) with a significant increase of the ACT score (from 19 â€‹± â€‹4.9 to 20 â€‹± â€‹4.0, p â€‹< â€‹0.001). CONCLUSIONS: Asthma in the elderly is characterized by low levels of symptom control. Educational interventions are strongly advocated in this age group in order to increase adherence to treatment and inhaler techniques.

Medicinal benefits of Nigella sativa in bronchial asthma: A literature review.

Nigella sativa L. (NS) seeds, known as black seed, is a spice and a traditional herbal medicine used in various diseases including bronchial asthma. This review aimed to assess the studies supporting the medicinal use of NS in asthma and to highlight future research priorities. Various medical databases were searched for the effects of NS and its active secondary metabolites in asthma inflammation and outcomes. There were fourteen preclinical studies describing multiple effects of NS in animal or cellular models of asthma including bronchodilation, anti-histaminic, anti-inflammatory, anti-leukotrienes and immunomodulatory effects. Furthermore, seven clinical studies showed improvements in different asthma outcomes including symptoms, pulmonary function and laboratory parameters. However, often these studies are small and used ill-defined preparations. In conclusion, NS could be therapeutically beneficial in alleviating airway inflammation and the control of asthma symptoms, but the evidence remains scanty and is often based on poorly characterised preparations. Accordingly, well-designed large clinical studies using chemically well characterised NS preparation are required.
