ABSTRACT
BACKGROUND: The decline in pulmonary function is a predictor of disease progression in patients with cystic fibrosis (CF). This study aimed to determine the decline rate of percent predicted forced expiratory volume in 1 s (ppFEV1) based on the data of the CF Registry of Turkey. The secondary aim was to investigate the risk factors related to the decline in ppFEV1. METHODS: A retrospective cohort study of CF patients over 6 years old, with pulmonary function data over at least 2 years of follow-up was extracted from the national CF registry for years 2017-2019. Patients were classified according to disease severity and age groups. Multivariate analysis was used to predict the decline in ppFEV1 and to investigate the associated risk factors. RESULTS: A total of 1722 pulmonary function test results were available from 574 patients over the study period. Mean diagnostic age was older and weight for age, height for age, and body mass index z scores were significantly lower in the group of ppFEV1 < 40, while chronic Pseudomonas aeruginosa (p < .001) and mucoid P. aeruginosa colonization (p < .001) were significantly higher in this group (p < .001). Overall mean annual ppFEV1 decline was -0.97% (95% confidence interval [CI] = -0.02 to -1.92%). The mean change of ppFEV1 was significantly higher in the group with ppFEV1 ≥ 70 compared with the other (ppFEV1 < 40 and ppFEV1: 40-69) two groups (p = .004). Chronic P. aeruginosa colonization (odds ratio [OR] = 1.79 95% CI = 1.26-2.54; p = .01) and initial ppFEV1 ≥ 70 (OR = 2.98 95% CI = 1.06-8.36), p = .038) were associated with significant ppFEV1 decline in the whole cohort. CONCLUSIONS: This data analysis recommends close follow-up of patients with normal initial ppFEV1 levels at baseline; advocates for early interventions for P. aeruginosa; and underlines the importance of nutritional interventions to slow down lung disease progression.
ABSTRACT
Background: Povidone, a synthetic polymer commonly used in various products such as antiseptics, cosmetics, and medications, has been associated with allergic reactions, including anaphylaxis. Despite its widespread use, cases of povidone-induced anaphylaxis, especially in children, are under-recognized. This case report aims to highlight the importance of considering povidone allergy in pediatric patients presenting with anaphylaxis. Case Presentation: We describe a 3-year-old boy who experienced anaphylaxis following the application of povidone-iodine antiseptic solution to a leg wound. He presented with generalized urticaria, angioedema, dyspnea, and cough. Prompt diagnosis and management were initiated in the emergency department. He experienced the second anaphylaxis with povidone-containing eye drops prescribed during an ophthalmology visit. Conclusions: Povidone allergy should be considered in pediatric patients presenting with anaphylaxis, especially those with idiopathic reactions or multiple drug allergies. Clinicians should emphasize patient education on label reading and the provision of adrenaline autoinjectors to prevent life-threatening reactions associated with povidone exposure.

INTRODUCTION: Cystic fibrosis transmembrane conductance regulator (CFTR) modulator drugs target the underlying defect and improve CFTR function. They are a part of standard care in many countries, but not all patients are eligible for these drugs due to age and genotype. Here, we aimed to determine the characteristics of non-eligible patients for CFTR modulators in the CF registry of Turkey (CFRT) to highlight their clinical needs. METHODS: This retrospective cohort study included CF patient data from the CFRT in 2021. The decision of eligibility for the CFTR modulator was determined according to the 'Vertex treatment-Finder' on the Vertex® website. Demographic and clinical characteristics of patients were compared between eligible (group 1) and ineligible (group 2) groups for CFTR modulators. RESULTS: Among the study population (N = 1527), 873 (57.2%) were in group 1 and 654 (42.8%) were in group 2. There was no statistical difference between groups regarding sex, meconium ileus history, diagnoses via newborn screening, FEV1 z-score, CF-associated complications, organ transplant history, and death. Patients in group 2 had a higher incidence of pancreatic insufficiency (87.7% vs. 83.2%, p = .010), lower median height z-scores (-0.87 vs. -0.55, p < .001), lower median body mass index z-scores (-0.65 vs. -0.50, p < .001), longer days receiving antibiotics due to pulmonary exacerbation (0 [interquartile range, IQR: 0-2] vs. 0 [IQR: 0-7], p = 0.001), and more non-invasive ventilation support (2.6% vs. 0.9%, p = 0.008) than patients in group 1. CONCLUSION: The ineligible group had worse clinical outcomes than the eligible group. This highlights their need for life-changing drugs to improve clinical outcomes.
ABSTRACT
As the life expectancy improves in cystic fibrosis, cardiac dysfunction is becoming an important risk factor for morbidity and mortality. Here, the association of cardiac dysfunction with proinflammatory markers and neurohormones between cystic fibrosis patients and healthy children was investigated. Echocardiographic measurements of right and left ventricular morphology and functions together with levels of proinflammatory markers and neurohormones (renin, angiotensin-II, and aldosterone) were obtained and analysed in a study group of 21 cystic fibrosis children aged 5-18 years and compared with age- and gender-matched healthy children. It was shown that patients had significantly higher interleukin-6, C-reactive protein, renin and aldosterone levels (p < 0.05), dilated right ventricles, decreased left ventricle sizes, as well as both right and left ventricular dysfunction. These echocardiographic changes correlated with hypoxia, interleukin-1 α, interleukin-6, C-reactive protein, and aldosterone (p < 0.05) levels. The current study revealed that hypoxia, proinflammatory markers, and neurohormones are major determinants of subclinical changes in ventricular morphology and function. While the right ventricle anatomy was affected by cardiac remodeling, the left ventricle changes were induced by right ventricle dilation and hypoxia. A significant but subclinical systolic and diastolic right ventricle dysfunction in our patients was associated with hypoxia and inflammatory markers. Systolic left ventricle function was affected by hypoxia and neurohormones. Echocardiography is a reliable and non-invasive method that is used safely in cystic fibrosis children for screening and detection of cardiac anatomical and functional changes. Extensive studies are needed to determine the time and frequency of screening and treatment suggestions for such changes.

BACKGROUND: Cystic fibrosis (CF) is an autosomal recessive disorder caused by CF transmembrane conductance regulator (CFTR) genetic variants. CFTR modulators improve pulmonary function and reduce respiratory infections in CF. This study investigated the clinical and laboratory follow-up parameters over 1 year in patients with CF who could not receive this treatment. METHODS: This retrospective cohort study included 2018 and 2019 CF patient data from the CF registry of Turkey. Demographic and clinical characteristics of 294 patients were assessed, who had modulator treatment indications in 2018 but could not reach the treatment. RESULTS: In 2019, patients younger than 18 years had significantly lower BMI z-scores than in 2018. During the 1-year follow-up, forced expiratory volumes (FEV1) and FEV1 z-scores a trend toward a decrease. In 2019, chronic Staphylococcus aureus colonization, inhaled antipseudomonal antibiotic use for more than 3 months, oral nutritional supplement requirements, and oxygen support need increased. CONCLUSIONS: Patients who had indications for modulator treatments but were unable to obtain them worsened even after a year of follow-up. This study emphasized the importance of using modulator treatments for patients with CF in our country, as well as in many countries worldwide.

BACKGROUND: We aimed to determine the number of cystic fibrosis (CF) patients recorded in the Cystic Fibrosis Registry of Türkiye (CFRT) who were in need of lung transplantation (LT) referral and examine clinical differences between patients who were LT candidates due to rapid forced expiratory volume in one second (FEV1) decline and LT candidates without rapid FEV1 decline in the last year to identify a preventable cause in patients with such rapid FEV1 decline. METHODS: All CF patients recorded in the CFRT in 2018 were evaluated in terms of LT. Patients were divided into those with FEV1 below 50% and in need of LT due to a decrease of 20% or more in the previous year (Group 1) and those who did not have FEV1 decline of more than 20% in the previous year but had other indications for LT (Group 2). Demographic and clinical features were compared between the two groups. RESULTS: Of 1488 patients registered in CFRT, 58 had a need for LT. Twenty patients were included in Group 1 and others in Group 2. Our findings did not reveal any significant variations in treatment, chronic infection status, or complications between the two groups. The average weight z-score was significantly higher in Group 1. Positive correlations were detected between weight z-score and FEV1 in 2017 in Group 1 and between FEV1 values in 2017 and 2018 in Group 2. CONCLUSIONS: There appears to be a relationship between the nutritional status and weight z-scores of CF patients and pulmonary function, which may indirectly affect the need for lung transplantation referral.

BACKGROUND: Cystic fibrosis (CF) registries play an essential role in improving disease outcomes of people with CF. This study aimed to evaluate the association of newly established CF registry system in Turkey on follow-up, clinical, growth, treatment, and complications of people with this disease. METHODS: Age at diagnosis, current age, sex, z-scores of weight, height and body mass index (BMI), neonatal screening results, pulmonary function tests, history of meconium ileus, medications, presence of microorganisms, and follow-up were evaluated and compared to data of people with CF represented in both 2017 and 2019 registry data. RESULTS: There were 1170 people with CF in 2017 and 1637 in 2019 CF registry. Eight hundred and fourteen people were registered in both 2017 and 2019 of whom z-scores of heights and BMI were significantly higher in 2019 (p = 0.002, p =0.039, respectively). Inhaled hypertonic saline, bronchodilator, and azithromycin usages were significantly higher in 2019 (p =0.001, p = 0.001, p = 0.003, respectively). The percent predicted of forced expiratory volume in 1 sec and forced vital capacity were similar in 2017 and 2019 (88% and 89.5%, p = 0.248 and 84.5% and 87%, p =0.332, respectively). Liver diseases and osteoporosis were significantly higher, and pseudo-Bartter syndrome (PBS) was significantly lower in 2019 (p = 0.011, p = 0.001, p = 0.001, respectively). CONCLUSIONS: The z-scores of height and BMI were higher, the use of medications that protect and improve lung functions was higher and incidence of PBS was lower in 2019. It was predicted that registry system increased the care of people with CF regarding their follow-up. The widespread use of national CF registry system across the country may be beneficial for the follow-up of people with CF.

BACKGROUND: Cystic fibrosis (CF) is a lethal recessive genetic disease caused by loss of function associated with mutations in the CF trans-membrane conductance regulator. It is highly prevalent (approximately 1 in 3,500) in Caucasians. The aim of this study was to compare demographic and clinical features, diagnostic tests, treatments, and complications of patients with CF whose newborn screening (NBS) with twice-repeated immune reactive trypsinogen testing was positive, normal, and not performed. METHODS: In this study, 359 of all 1,488 CF patients recorded in the CF Registry of Turkey in 2018, who had been born through the process of NBS, were evaluated. Demographic and clinical features were compared in patients diagnosed with positive NBS (Group 1), normal (Group 2), or without NBS (Group 3). RESULTS: In Group 1, there were 299 patients, in Group 2, there were 40 patients, and in Group 3, there were 20 patients. Among all patients, the median age at diagnosis was 0.17 years. The median age at diagnosis was higher in Groups 2 and 3 than in Group 1 (P = 0.001). Fecal elastase results were higher in Group 2 (P = 0.033). The weight z-score was lower and chronic Staphylococcus aureus infection was more common in Group 3 (P = 0.017, P = 0.004, respectively). CONCLUSIONS: Frequency of growth retardation and chronic S. aureus infection can be reduced with an early diagnosis using NBS. In the presence of clinical suspicion in patients with normal NBS, further analyses such as genetic testing should be performed, especially to prevent missing patients with severe mutations.

The pathogenesis of chronic spontaneous urticaria (CSU) is incompletely understood. There is a growing interest in the role of the coagulation cascade in chronic urticaria. Rotational thromboelastometry (ROTEM) assay enables the global assessment of coagulation status. In the present study, we aimed to test the coagulation profile in children with CSU using ROTEM and correlate these parameters with those of a healthy group. A total of 24 children with active CSU (11 girls and 13 boys) 8 to 17 years of age and age-matched and sex-matched 30 healthy control participants were enrolled in the study. ROTEM assays (intrinsic thromboelastometry and extrinsic thromboelastometry) were used to measure and analyze coagulation time, clot formation time, and maximum clot firmness. The CSU patients and controls did not differ in age, sex, erythrocyte, neutrophil, and platelet counts. Also, ROTEM parameters did not show any difference between the 2 groups. ROTEM is increasingly being used as a tool for monitoring coagulation status. In this study, ROTEM parameters did not show any difference between CSU patients and the healthy group. Further studies are needed to confirm our findings on a larger number of CSU patients.

INTRODUCTION: Atopic dermatitis (AD) is a chronic inflammatory disease caused by the complex interaction of genetic, immune and environmental factors such as food and airborne allergens. The atopy patch test (APT) is a useful way to determine delayed-type hypersensitivity reactions to food and aeroallergens. Many studies have also suggested that food additives are associated with dermatologic adverse reactions and the aggravation of pre-existing atopic dermatitis symptoms. AIM: To elucidate the contact sensitivity to food additives in children suffering from AD by using standardized atopy patch testing. MATERIAL AND METHODS: A total of 45 children with AD and 20 healthy children have been enrolled. All the children have regularly consumed food containing additives, and were subjected to atopy patch tests. RESULTS: In total, 28 (62%) children with AD and 4 (20%) healthy children have had positive patch test reactions to ≥ 1 allergens. There has been a significant difference (p = 0.04) between the groups in terms of the positivity rate in the patch test and the most common allergen that elicited positive patch test results in the AD group was azorubine (n = 11, 24.4%, p = 0.014). CONCLUSIONS: In our study, contact sensitivity was detected more frequently in AD patients. Food additives may play a role in the development and exacerbation of AD. Atopy patch testing with food additives can be useful in the treatment and follow-up of children with AD.
ABSTRACT
BACKGROUND: A better understanding of cystic fibrosis transmembrane conductance regulator biology has led to the development of modulator drugs such as ivacaftor, lumacaftor-ivacaftor, tezacaftor-ivacaftor, and elexacaftor-tezacaftor-ivacaftor. This cross-sectional study evaluated cystic fibrosis (CF) patients eligible for modulator drugs. METHODS: Data for age and genetic mutations from the Cystic Fibrosis Registry of Turkey collected in 2018 were used to find out the number of patients who are eligible for modulator therapy. RESULTS: Of registered 1488 CF patients, genetic analysis was done for 1351. The numbers and percentages of patients and names of the drugs, that the patients are eligible for, are as follows: 122 (9.03%) for ivacaftor, 156 (11.54%) for lumacaftor-ivacaftor, 163 (11.23%) for tezacaftor-ivacaftor, and 57 (4.21%) for elexacaftor-tezacaftor-ivacaftor. Among 1351 genotyped patients total of 313 (23.16%) patients are eligible for currently licensed modulator therapies (55 patients were shared by ivacaftor and tezacaftor-ivacaftor, 108 patients were shared by lumacaftor-ivacaftor and tezacaftor-ivacaftor, and 22 patients were shared by tezacaftor-ivacaftor and elexacaftor-tezacaftor-ivacaftor groups). CONCLUSIONS: The present study shows that approximately one-fourth of the registered CF patients in Turkey are eligible for modulator drugs. As, frequent mutations that CF patients have in Turkey are different from North American and European CF patients, developing modulator drugs effective for those mutations is necessary. Furthermore, as modulator drugs are very expensive currently, financial support of the government in developing countries like Turkey is noteworthy.

Background: Chronic disease of children can cause changes in the health-related quality of life (HrQoL) of the family members. Aims: To evaluate the HrQoL of healthy siblings of children with chronic disease. Study Design: Cross-sectional study. Methods: The study included healthy sibling of children with chronic disease (cerebral palsy, epilepsy, diabetes, celiac disease, hematologic/oncologic disease, or asthma) and healthy sibling of healthy children to evaluate the quality of life. We used the Pediatric Quality of Life Inventory questionnaire; the physical health and psychosocial health scores were calculated using the responses of the sibling and parent. The primary endpoint was the comparison of HrQoL scores of healthy siblings of children with chronic disease and that of healthy siblings of healthy children. Results: This study included a respective healthy sibling of 191 children with chronic disease and healthy sibling of 100 healthy children. The physical health, psychosocial health, and total health scores of healthy siblings of children with chronic disease were significantly lower than that of healthy siblings of healthy children (p<0.001). Among the healthy siblings of children with chronic disease, the lowest psychosocial health score was found in the siblings of children with cerebral palsy, hematologic/oncologic disease, and asthma (p<0.001). The global impact on the quality of life for healthy siblings of children with chronic disease was significantly higher in the self-report of the children than that of the parents (30.4% versus 15.1%, p<0.05). Conclusion: Most healthy siblings of children with chronic disease are physically and psychosocially affected and there is low parental awareness of this condition. This can increase the risk of emotional neglect and abuse of these children. Therefore, special support programs are needed for the families of children with chronic diseases.

BACKGROUND: The term "H syndrome" was coined to denote the major clinical findings, which include hyperpigmentation, hypertrichosis, hearing loss, hepatosplenomegaly, hyperglycaemia, hypogonadism, hallux flexion contractures, and short height. OBJECTIVE: To report the clinical, endocrinological, histochemical, and genetic findings of three siblings. METHODS: Skin and liver biopsies were taken to investigate the histochemical characteristics of hyperpigmented hypertrichotic skin lesions and massive hepatomegaly. The levels of basal serum thyroid hormones, oestradiol, total testosterone, follicle-stimulating hormone, luteinising hormone, and stimulated growth hormone (GH) were measured to investigate the endocrine aspects of the syndrome. Mutation analysis was carried out in all six exons and exon-intron boundaries of SLC29A3 by direct sequencing. RESULTS: Physical examination of the patients revealed common charac-teristic findings of H syndrome. Additional clinical findings were sectorial iris atrophy in the younger sister. Laboratory evaluation revealed microcytic anaemia, markedly increased erythrocyte sedimentation rate and C-reactive protein levels, and humoral immune deficiency in the younger siblings, who presented with recurrent fever and sinopulmonary infection. Two different GH stimulation tests revealed GH deficiency in the younger sister with short stature. Liver and skin biopsies revealed polyclonal lymphohistiocytic and plasma cell infiltration. Sequencing of SLC29A3 in the three siblings revealed a novel homozygous mutation in exon 6, which caused the transition of arginine to tryptophan. CONCLUSION: This study not only extended the clinical and mutation spectrum of SLC29A3 in H syndrome, but also showed that short children should be assessed according to the guidelines for short stature in children.

AIM: It has been shown by a great number of studies that the correct use of adrenaline auto injectors prescribed to patients with anaphylaxis is associated with the design of the auto injector, in addition to training. The aim of this study was to compare the skills of adults in using two different auto injectors prescribed to patients with anaphylaxis. MATERIAL AND METHODS: Parents of patients aged between 1 and 18 years who referred to allergy outpatients were included in the study. RESULTS: A total of 630 volunteers from nine centers were included in the study. Four hundred fifty-seven (72.5%) of the participants were females and 235 (37.3%) were undergraduates. The rate of showing all the steps of auto injector trainers correctly by the participants was found as (60.2%) (n=379) for EpiPen and 42.9% (n=270) for Penepin (p<0.001). The most frequent mistake with both auto injector trainers was the step of "place appropriate injection tip into outer thigh/press the trigger so it clicks." When the preferences of the volunteers were asked after training and application, 527 (83.7%) chose EpiPen, stating that it was easier and simpler to use. CONCLUSIONS: Our study showed that the correct usage rates of both adrenaline auto injectors were much lower than expected and there could be mistakes in the application of both. It could be appropriate to make improvements in the design of Penepin, which is still the only available adrenaline auto injector in Turkey, such that its application steps will be simpler and quicker.
ABSTRACT
Increased thrombophilic tendency in patients with cystic fibrosis (CF) has recently been reported. The determinants of thrombosis in children with CF remain largely unknown. Our aim in this study was to evaluate the thromboelastography (TEG) profile of children with CF through ROTEM (whole blood rotation thromboelastometry). Nineteen patients with CF and 20 controls were included in the study. Whole blood count, prothrombin time, activated prothrombin time, fibrinogen, d-dimer levels, and ROTEM assays (INTEM, EXTEM) were performed. Clotting time, clot formation time (CFT), and maximum clot firmness (MCF) were determined by INTEM and EXTEM analysis. In INTEM assay, MCF ( P = .001) value was significantly increased and CFT ( P = .031) value was decreased in patients with CF compared with those of the control group. In the EXTEM assay, there was a similar significant increase in MCF ( P = .023) value in patients with CF compared with that of the control group. There was a significant positive correlation between fibrinogen levels and MCF in EXTEM ( r = .72) and INTEM ( r = .76) assays, whereas there was a negative correlation with CFT in EXTEM ( r = -.61) and INTEM ( r = -.67). The results of our study indicated that TEG profiles in patients with CF were more hypercoagulable compared with those of the control group.

Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is a rare, potentially life-threatening, drug-induced hypersensitivity reaction that includes rash, hematologic abnormalities, lymphadenopathy, and internal organ involvement. The pathogenesis of DRESS syndrome is partially understood. Various medications have been described as the cause of DRESS syndrome. Phenytoin and allopurinol are the most commonly reported culprit drugs, although more than 50 drugs can induce DRESS syndrome. Members of the cytochrome P450 (CYP) superfamily are the most commonly involved enzymes in metabolism of drugs such as phenytoin. This case report addresses the influence of CYP2C9 genetic polymorphism (a single nucleotide polymorphism) on phenytoin drug metabolism, thereby causing DRESS syndrome.
ABSTRACT
BACKGROUND: Asthma exacerbations lead to frequent emergency visits and hospitalizations, and are associated with high morbidity and occasionally mortality. New therapeutic strategies are needed. We sought to investigate whether the addition of high-dose inhaled budesonide to standard therapy would shorten the length of stay (LOS) in hospital of children admitted for asthma exacerbations. METHODS: The study was designed as a single-center, double-blind, placebo-controlled and parallel-group trial. Children aged 7-72 months and admitted with an asthma exacerbation clinical asthma score (CAS) of between 3 and 9 were allocated to either the budesonide (n = 50) or the placebo (n = 50) group. Hospital LOS was compared between children who received 2 mg/day of budesonide versus placebo in addition to standard management of asthma exacerbation involving oxygen inhalation and ß2-agonist, anticholinergic and oral corticosteroid therapy. All patients were assessed every 4 h. Children with a CAS <3, a peripheral oxygen saturation >95% and normal pulmonary function, and those with a symptom-free period of at least 4 h after salbutamol treatment were discharged. RESULTS: Total hospital LOS was significantly shorter in the budesonide group than in the placebo group (median: 44 vs. 80 h, respectively; p = 0.01). When compared with placebo, the number of inpatients was significantly less in the budesonide group at all the assessed end points (Kaplan-Meier; p = 0.022). Additionally, nebulized budesonide was found to reduce the overall cost of treatment. CONCLUSION: We demonstrated that, for children hospitalized for asthma exacerbations, an additional 2 mg/day of nebulized budesonide significantly reduced hospital LOS as well as the overall cost of treatment.

BACKGROUND: Allergic rhinitis is a type I allergic disease of the nasal mucosa, and is characterized by paroxysmal sneezing, watery rhinorrhea, and nasal blockage. In seasonal allergic rhinitis subjects, even subthreshold allergen doses have been found to cause inflammatory cell infiltration in the nasal mucosa. This study aimed to investigate the presence of nasal obstructions and symptoms in seasonal allergic rhinitis subjects by assessing an exercise challenge test (ECT) outside of the pollen season. METHODS: Twenty patients and 20 healthy children who were admitted to the Osmangazi University Medical School Pediatric Allergy Clinic were included in the study in a pollen free season. The total nasal airflow and visual analog scale (for rhinorrhea, nasal congestion, sneezing, and itching) and pulmonary function tests were evaluated before and after each ECT. The nasal airflow and resistance changes were evaluated with anterior rhinomanometry. RESULTS: Eight patients and one healthy child had nasal obstructions after the ECT. There was a significant difference in the exercise-induced nasal obstructions between the 2 groups (p = 0.02). Eighteen children with exposure to tobacco smoke in the patient and control groups had lower forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), and forced expiratory flow 25% to 75% (FEF25-75 ) values than the children without exposure to tobacco smoke. CONCLUSION: The prevalence of exercise-induced nasal obstruction in children with seasonal rhinitis out of the pollen season is 40%. We showed that minimal persistent inflammation and nasal symptoms can also be diagnosed in rhinitis children in a symptom-free period.

A 17-year-old girl was admitted to our unit with weight loss, dyspnoea, arthralgia and sinusitis. Her medical history was noteworthy for bronchial asthma and she required systemic steroid therapy. Her mother had a history of eosinophilic granulomatosis with polyangiitis (EGPA). Laboratory tests revealed excessive eosinophilia and elevated erythrocyte sedimentation. The assay for peripheral antineutrophil cytoplasmic antibodies was negative. Histopathological examination of lung biopsy revealed EGPA. The patient was treated with methylpredinosolone; her eosinophil count normalised and she began to improve clinically and radiographically. There is no genetic factor to influence susceptibility to this disease. To the best of our knowledge, this is the second report of familial EGPA disease in the literature, with a mother and daughter both being affected. EGPA disease should be kept in mind in a patient with uncontrolled asthma and eosinophilia with a positive family history for EGPA.
