RESUMO
OBJECTIVE: Pulmonary embolism (PE) poses a significant threat to children, and nonspecific symptoms lead to delayed diagnosis. The emergence of coronavirus disease 2019 (COVID-19) has increased the complexity as it is associated with similar symptoms and increased risk of thrombotic complications. This study aimed to assess the risk factors, clinical presentations, and diagnostic features of PE in pediatric patients and to examine the impact of the COVID-19 pandemic on children with PE. MATERIALS AND METHODS: We conducted a retrospective descriptive study examining the clinical and diagnostic data of 44 pediatric patients with radiologically confirmed PE. The study compared and analyzed patients diagnosed before and during the COVID-19 pandemic. RESULTS: In the study, 21 of 44 pediatric patients were diagnosed in the 4 years before the COVID-19 pandemic, and 23 were diagnosed with PE during the COVID-19 pandemic. The mean time to diagnosis was 8 (2 to 14) days before the pandemic and 1 (1 to 2) days during the pandemic ( P < 0.001). The most common associated condition in both groups was infection (65.9%). Dyspnea (65.9%) and tachypnea (50.0%) were common symptoms. Except for deep vein thrombosis, there were no significant differences according to associated conditions between the groups ( P = 0.001). Pulmonary emboli were anatomically detected using computed tomography angiography, showing bilateral involvement in 45.4% of patients, segmental artery involvement in 38.6%, and main artery involvement in 15.9%. CONCLUSION: The COVID-19 pandemic heightened suspicion of pediatric PE and accelerated diagnosis. Standardized diagnostic guidelines are increasingly necessary to balance accurate diagnosis with avoiding excessive imaging.

INTRODUCTION: Biologic modifying agents are associated with an increased risk for infection with mycobacteria. The aim of this study is to document patients who received different biologic modifying therapies in our pediatric rheumatology department and the possibility of development of tuberculosis (TB). METHODOLOGY: This retrospective study was conducted in Ankara City Hospital. Pediatric patients who were treated with biologic modifying agents between 2010-2020 were documented. Development of TB and the risk factors were assessed in this patient group. RESULTS: There were 72 patients who were treated with different biologic modifying agents. Tuberculin skin test (TST) was positive in 7 (9.7%) patients during follow up. Three patients whose TST was positive had received canakinumab, 2 received etanercept, 1 received adalimumab and 1 received anakinra. Median duration of therapy was 43.5 (16.5-168) months for these patients and the duration was longer than patients who did not develop latent tuberculosis (p = 0.04). Patients who developed latent TB under treatment were significantly older than the patients who did not (p = 0.01). CONCLUSIONS: According to our findings, 9.7% of pediatric patients who received biologic modifying agent therapy developed latent TB. Patients who developed latent TB were older, and the duration of treatment was longer than patients who did not develop latent TB. Although not statistically significant, canakinumab, which is known as an agent less likely to cause TST conversion, was in fact the most common agent that caused TST conversion.

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: Community-acquired pneumonia (CAP) in children continues to be one of the prominent causes of pediatric morbidity and mortality worldwide. By determining the risk factors associated with the development of complicated CAP (CCAP), new approaches for early diagnosis and effective treatment can be identified. METHODS: This retrospective cohort study enrolled patients with CAP and CCAP who visited the pediatric ward of the study hospital between January 1, 2017 and December 31, 2017. For patients with CCAP, data regarding medical procedures performed, surgical intervention, and hospitalization duration were collected. RESULTS: A total of 111 patients, 93 (83.7%) with CAP and 18 (16.3%) with CCAP, aged between 3 months and 18 years were hospitalized because of severe pneumonia. The mean age of the patients was 3.6 ± 1.2 years and 60 (54%) of them were female. The mean age of patients with CCAP was higher than that of patients with CAP (4.2 ± 3.3 vs. 2.8 ± 2.1 years respectively); however, the difference was not significant (p = 0.012). Patients with CCAP exhibited a significantly higher C-reactive protein level than those with CAP (10.06 ± 7.55 vs. 4.43 ± 3.37 g/L respectively; p = 0.007). Hypoxia upon admission was noted more commonly in the CCAP group than in the CAP group (p < 0.001). CONCLUSION: Findings related to hypoxia, respiratory distress, and pleural effusion on imaging are important distinguishing factors associated with the development of complications in patients hospitalized with CAP. Therefore, CCAP etiology, diagnosis, and treatment approaches should be established and protective measures adopted.

Background: Previously, lipopolysaccharide-responsive beige-like anchor (LRBA) deficiency was categorized as a subtype of common variable immune deficiency. Research shows that LRBA deficiency is caused by dysregulation of T cell activation and expansion; it is placed under the category of immune dysregulation with cytotoxic T lymphocyte-associated protein 4 (CTLA-4) haploinsufficiency. Cohort studies have revealed a broad spectrum of clinical manifestations and variable phenotype expression, including immune dysregulation [enteropathy, autoimmune cytopenia, interstitial lung disease (ILD), etc.] on 1 hand and immune deficiency (hypogammaglobulinemia, recurrent infections, bronchiectasis, etc.) on the other hand. Chronic lung disease is frequently seen in LRBA deficiency and is associated with poor outcomes. Case Presentation: This case report evaluates a female who presented with recurrent pneumonia and bronchiectasis but did not respond to treatment; she was lastly diagnosed with ILD with detailed clinical, radiological, and pathological workup. Conclusions: The respiratory characteristics of patients with LRBA deficiency should be investigated, monitored, and treated from the time of its diagnosis. The awareness and involvement of pulmonologists to pulmonary morbidity of patients with LRBA deficiency in workup and clinical decision making are crucial.

BACKGROUND: Cell culture increases both diagnostic specificity and sensitivity of primary ciliary dyskinesia (PCD) and the most important reason to use cell culture for definitive diagnosis in PCD is to exclude secondary ciliary defects. Here we aimed to evaluate the cilia functions and cilia ultrastructural abnormalities after ciliogenesis of cell culture in patients with definitive diagnosis of PCD. We also aimed to compare high speed videomicroscopy (HSVM) results of patients before and after ciliogenesis and to compare them with electron microscopy, genetic and immunofluorescence results in patients with positive diagnosis of PCD. METHODS: This study was conducted as a cross-sectional study in patients with PCD. HSVM, transmission electron microscopy (TEM) and immunofluorescence staining results of the nasal biopsy samples taken from patients with the definitive diagnosis of PCD were evaluated and HSVM findings before and after cell culture were described. RESULTS: Ciliogenesis and regrowth in the cell culture occurred in the nasal biopsy sample of eight patients with PCD. The mean age of the patients was 15.5±4.2 years (8.5-18 years). Mean beat frequency was found to be 7.54±1.01 hz (6.53-9.45 hz) before cell culture, and 7.36±0.86 hz (6.02-7.99 hz) after cell culture in the nasal biopsy of patients. There was no significant difference in the beat frequency of PCD patients before and after cell culture. Ciliary function analysis showed the similar beating pattern before and after cell culture in patients with PCD. CONCLUSIONS: This study showed us that there was no difference between cilia beat frequency and beat pattern before and after cell culture in patients with definitive diagnosis of PCD and repeated HSVM would be a useful diagnostic approach in patients who have no possibility to reach other diagnostic methods.

INTRODUCTION: Congenital lobar emphysema (CLE), a rare developmental lung malformation, involves the hyperaeration of one or more lung lobes caused by partial obstruction and occurs at a rate of 1/20,000-30,000 live births. Here, we aimed to retrospectively examine the clinical, radiological, and bronchoscopy findings of patients with CLE who were diagnosed and treated by surgical or non-surgical (conservative) approaches at our center and compared our results with those in the literature. METHODS: We examined the clinical, radiological, and bronchoscopy findings of 20 patients with CLE aged 0-18 years at our center between 2013 and 2020. In addition, we examined the symptoms and findings recorded during the patients' follow-up in this retrospective descriptive study. RESULTS: The median age of 20 patients with CLE at diagnosis was 3.2 years (range 1 day-17 years). Respiratory distress and mediastinal shift were more prominent in patients who underwent surgery, and they were diagnosed at an earlier age compared with patients who were followed up conservatively (p = 0.001, 0.049, 0.001, respectively). Neither the pulmonary lobe involvement nor the bronchoscopy findings were found to be indicative of surgery. DISCUSSION: We observed that respiratory distress and mediastinal shift were more prominent in patients with a diagnosis of CLE who underwent surgery compared with patients who were conservatively followed up. Moreover, we observed that those who underwent surgery were diagnosed with CLE at an earlier age. In line with the literature, the pulmonary symptoms and CLE-related imaging findings in our study were reduced during conservative follow-up.

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 reported to be a risk factor for drug hypersensitivity. However, there are conflicting data about true prevalence of drug hypersensitivity in children with CF. METHODS: The suspicious drug hypersensitivity reactions (DHRs) of children with CF were enquired by the European Network for Drug Allergy (ENDA) questionnaire, and skin tests and/or drug provocation tests were performed according to the established guidelines. RESULTS: Two hundred and nineteen children (48.9% boys; median [IQR] age, 8.4 years [4.8-12.4 years]) with cystic fibrosis were included in the study, among which 22 patients with 24 suspected DHRs were evaluated. Most of the suspected DHRs were of non-immediate (n = 16, 66.6%) type, and the offending drugs were amoxicillin-clavulanic acid (n = 7), macrolides (n = 4), trimethoprim-sulfamethoxazole (TMP/SMX) (n = 2), piperacillin-tazobactam (n = 1), pancrelipase (n = 1), and ursodeoxycholic acid (n = 1). Eight (33.3%) of the DHRs were classified as immediate (ceftriaxone [n = 2], ceftazidime [n = 2], meropenem [n = 1], AmBisome [n = 2], and vancomycin [n = 1]). The main clinical presentations were maculopapular eruption (41.6%) and urticaria (37.5%), accompanied by angioedema (8.3%), flushing (12.5%), and vomiting (8.3%). Nine skin tests (with beta-lactam protocol in 6 patients) and 24 DPTs were performed, and none of the skin tests revealed a positive result; however, 2 DPTs with TMP/SMX were positive. CONCLUSION: Actual drug hypersensitivity was demonstrated in 2 of 219 patients (0.9%) with non-beta-lactam antibiotics. These results conflict with previous researches that showed higher drug hypersensitivity rates but are consistent with some recent studies. Allergological diagnostic workup is mandatory in patients with cystic fibrosis in case of a suspicious DHR.

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.

INTRODUCTION: Recurrent pulmonary infections, wheezing and stridor due to swallowing dysfunction, esophageal dysmotility, gastroesophageal reflux, tracheomalacia and bronchomalacia are frequently seen complications after esophageal atresia and tracheo-esophageal fistula (EA-TEF) surgeries. This study aimed to investigate the frequency and causes of respiratory problems and to evaluate the factors that affect respiratory morbidity in patients who had undergone EA-TEF repair in a tertiary referral center. METHODS: Preoperative and postoperative records of patients with EA, TEF + EA and isolated EA were examined retrospectively. Accompanied diseases and swallowing dysfunction symptoms were questioned. Bronchoalveolar lavage results were investigated if the patient had flexible bronchoscopy. RESULTS: A total of 71 children with EA were included in the study, and seven patients who did not have follow-up after surgery were excluded. 46 of the 64 patients continue regular follow-up visits in our department. Male sex, primary EA repair in another center, EA type C, accompanying genetic anomalies, severe tracheomalacia, late per oral feeding (1 year after surgery), and severe GER were found to cause significantly higher incidence of coughing, recurrent wheezing, recurrent pneumonia, and bronchiectasis despite surgical and medical treatments (p = 0.048, p = 0.045, p = 0.009, p = 0.029, p = 0.025). CONCLUSION: Even if anatomical anomalies are corrected by surgery in patients who underwent EA repair, precautions can be taken for GERD, laryngotracheomalacia, and swallowing dysfunction, and effective pulmonary rehabilitation can be initiated with early multidisciplinary approach before the development of respiratory tract symptoms.

OBJECTIVES: Pulmonary neuroendocrine cells (NEC) increase with age due to pulmonary maturity. The aim of this study was to determine whether open lung biopsies from patients with interstitial lung diseases have increased pulmonary NEC compared with neuroendocrine cell hyperplasia of infancy (NEHI). Our second aim was to assess pulmonary NECs in the lung autopsy of children without lung disease who died from different causes. METHODS: Lung tissue of 5 infants with NEHI; 21 patients with pediatric interstitial lung disease (chILD); 17 lung autopsies of infants at varying age without lung disease were included. The percentage of the airways containing neuroendocrine cells, the average percentage of neuroendocrine cells (NECs) per airway, and the number of neuroendocrine bodies (NEBs) in each case were analyzed. RESULTS: The mean percentage of the airways containing neuroendocrine cells were 95% in the NEHI group, 30% in the chILD group, 89% under Intrauterine 37 weeks, 70% between intrauterine 37 to 40 weeks, 52% at postnatal 4 days to 6 months of autopsy ages. In the NEHI group, diffuse NE cell distribution and large NEBs were noticed in the lung biopsy. In the chILD group, neuroendocrine cells were dispersed, did not form clusters and NE cells showed solitary distribution. In the lung autopsy group, linear NE cells were detected at younger aged fetuses and solitary distribution of NE cells was detected with the older increasing age. CONCLUSIONS: Our findings confirm that NECs are seen in many other childhood interstitial lung diseases; NE cell hyperplasia may be a marker of decreased pulmonary development and NE cells decrease with the increasing age of the fetus during Intrauterine life.

Primary ciliary dyskinesia (PCD) is a rare, genetic disease characterized by ciliary dysfunction. Patients may present with respiratory distress during neonatal period; chronic sinopulmonary disease, bronchiectasis, recurrent otitis media, sinusitis and infertility in later periods. About 50% of PCD patients have situs inversus totalis and 6-12% have situs ambiguous known as heterotaxy syndromes. Herein, we present a case of PCD and accompanying situs inversus who had acute abdominal pain and was diagnosed with torsion of one of the multiple spleens. Evaluation of acute abdominal pain in these patients has great importance since the internal organs are not at their typical locations.

BACKGROUND AND OBJECTIVE: Primary ciliary dyskinesia (PCD) is a rare and genetically heterogeneous disease and the severity of the disease related with genetic analysis has been described in some previous studies. The main aim of our study was to describe the clinical characteristics and laboratory findings of patients with genetically diagnosed PCD and to investigate the correlation between clinical, radiologic, and laboratory findings and genetic analyses of these patients. METHOD: This is a cohort study in which we analyzed the clinical characteristics, laboratory findings, and genetic results of 46 patients with genetically diagnosed PCD through whole-exome sequencing at our single center from a total of 265 patients with PCD within a 5-year period. RESULTS: Genetic analysis revealed pathogenic variants in DNAH5 (n = 12 individuals, 12 families), CCDC40 (n = 9 individuals, six families), RSPH4A (n = 5 individuals, three families), DNAH11 (n = 4 individuals, four families), HYDIN (n = 5 individuals, five families), CCNO (n = 4 individuals, four families), DNAI1 (n = 2 individuals, one family), ARMC4 (n = 2 individuals, two families), TTC25 (n = 1), DNAH1 (n = 1), and CCDC39 (n = 1) genes. Although not statistically significant, the age at diagnosis was lower (median: 3 years; range, 6 months-4 years) in patients with CCNO pathogenic variants due to the early reporting of symptoms, and the median body mass index (BMI) and BMI z scores were lower in patients at 18.7 and 16 kg/m2 , and -0.78 and -1.2 with CCDC40 and CCNO pathogenic variants, respectively. The median forced expiratory flow in 1 second (FEV1%), forced vital capacity (FVC%), and forced expiratory flow (FEF)25-75% were 53%, 64%, and 28%, respectively; these parameters were also lower in the CCDC40 group than in the other groups. There was no significant correlation between the genetic results and symptoms, radiologic findings, and microbiologic data of patients with PCD. CONCLUSION: In PCD, there was significant heterogeneity of lung disease, patients who had pathogenic variants in CCNO presented earlier, and those with CCDC40 and CCNO had worse lung disease, and poorer nutritional status compared with the other subgroups. We hope that whole genotype-phenotype and clinical relationships will be identified in PCD.

AIM: To evaluate the relationship between respiratory problems and oxidative stress markers in exhaled breath condensate (EBC) of patients with esophageal atresia (EA). METHODS: EA cases with respiratory problems were evaluated retrospectively for age, gender, the type of atresia, surgical treatment, outcome and respiratory symptoms. The results of gastroesophageal reflux (GER) treatment including the use of proton pump inhibitor (PPI) and fundoplication were also documented. EBC samples of 500-1000⯵l were obtained by Ecoscreen machine in all cases. The levels of Glutathione (Glut), 8-isoprostane (8-iso), cysteinyl-leukotriene (Cys-LT) were measured with ELISA. Results were compared with healthy control subjects (CG, nâ¯=â¯26) and the relationship between oxidative stress markers and respiratory symptoms was evaluated. The results of GER treatment and oxidative stress markers in EBC were also correlated. RESULTS: Twenty-nine patients with a mean age of 8.8â¯years (3-14 years) were included. The male/female ratio was 16:13. The EA presented with distal fistula in 27 cases. While no fistula was observed in 1 case, both proximal and distal fistulae were present in another single case. Associated anomalies, most of which were cardiovascular anomalies, were observed in 65.5% (nâ¯=â¯19) of cases. The median Glut level was 1.03â¯mM/ml (0.93-1.15), iso-8 was 38.8â¯pg/mL (32.03-76.2) and Cys-LT was 0.44â¯pg/mL (20.17-61.3) in patients with EA. The median levels of oxidative markers in CG were 1.23â¯mM/mL (1.13-1.36), 66.3â¯pg/mL (33.5-106.7), and 56.9â¯pg/mL (27.4-80.1), respectively. Glut levels were significantly lower in EA cases compared to CG (pâ¯=â¯0.01). There was no significant difference between the groups regarding 8-iso and CYS-LT levels (pâ¯=â¯0.9, pâ¯=â¯1.0). Cys-LT levels were significantly lower in patients with PPI treatment [21.7â¯pg/mL (18.6-48.1)], when compared to patients without PPI treatment [41.1â¯pg/mL (22.5-83.1)] (pâ¯=â¯0.04) and healthy subjects [56.9â¯pg/mL (27.4-80.1)] (pâ¯=â¯0.017). The 8-iso levels were significantly decreased in cases with fundoplication compared to the patients without fundoplication (pâ¯=â¯0.02). CONCLUSION: Glut - an antioxidant agent - levels were significantly lower in EBC of EA cases. The decrease in Cys-LT levels in cases with PPI treatment and in 8-iso levels in patients with fundoplication suggests that the oxidative damage in EBC of EA cases may be correlated with GER and its management. TYPE OF STUDY: Case control study LEVEL OF EVIDENCE: Level III.

BACKGROUND: Treatment decisions for the management of bronchiectasis include medical treatment, such as antibiotics, chest physiotherapy, and surgical procedures. Here, we aimed to review the effect of lung resection on longitudinal growth, clinical course of patients depending on annual exacerbation rates, and pulmonary function tests (PFTs) and compare them with the results of only medically treated children with non-cystic fibrosis (non-CF) bronchiectasis. METHODS: The medical records of patients with non-CF bronchiectasis were retrospectively analyzed. Patients who underwent lobectomy/segmentectomy/pneumonectomy were categorized as "surgery group" (n = 29). Age- and gender-matched patients who were only medically treated were selected as "medical group" (n = 33). Annual data of patients were included till the end of postoperative second year in the surgery group and third year of medical treatment in the medical group. RESULTS: Mean baseline height z-score was lower in the surgery group, and mean baseline PFT values were all lower in the surgery group than those in the medical group (p < 0.05). In the surgery group, mean values of height z-score were -1.68 ± 0.92 at the time of surgery and improved to -1.42 ± 1.22 and -1.34 ± 1.05 in the first and second postoperative years, respectively, and annual intravenous antibiotic requirements decreased significantly (p < 0.05); however, mean body mass index (BMI) z-score values and PFT parameters did not change significantly. In the medical group, height z-score mean values and PFT parameters showed nonsignificant improvement but annual exacerbation frequency, annual intravenous, and oral antibiotic requirements decreased significantly. CONCLUSION: Surgical management of non-CF bronchiectasis has no significant effect on BMI z-scores, annual exacerbation frequencies, oral antibiotic requirements and lung function tests; but can lead to significant improvement on height z-scores and decrease need of annual intravenous antibiotic requirements for acute severe exacerbations despite small number of patients in this study.

INTRODUCTION: Non-cystic fibrosis(CF) bronchiectasis has been recognized in children for the past 200 years. Early childhood pneumonia and underlying conditions such as immunodeficiency, primary ciliary dyskinesia(PCD), and congenital lung pathology should be considered in the etiology. The aim of our study was to describe the clinical characteristics, laboratory, and radiological findings of a large population of patients with non-CF bronchiectasis at a tertiary center. METHODS: We analyzed the clinical findings of 187 patients diagnosed with non-CF bronchiectasis over a period of 10 years (January 2005-December 2015) at the Hacettepe University Faculty of Medicine Department of Pediatric Pulmonology. RESULTS: The median age at the time of diagnosis of non-CF bronchiectasis was 8 years (1-18 years). Consanguinity was positive in 59.4% (nâ¯=â¯111) of patients and 19.8% (nâ¯=â¯37) of patients had a positive family history for non-CF bronchiectasis. Common causes were PCD in 51.3% (nâ¯=â¯96), immunodeficiency in 15% (nâ¯=â¯28), history of tuberculosis in 5.9% (nâ¯=â¯11), post-infectious complication in 3.2% (nâ¯=â¯6) and other anomalies in 2.1% (nâ¯=â¯4) of patients. The frequency of pulmonary lobe involvement was as follows: 71.1% left-lower lobe, 59.4% right lower lobe, 54% right-middle lobe, 26.8% left lingula, 13.9% right upper lobe, and 9.6% left upper lobe. CONCLUSIONS: Diagnosis of non-CF bronchiectasis is often delayed because of a failure to recognize the significance of symptoms. Through clinical investigation, including a HRCT scan of the chest, sweat test, studies of immune function, and ciliary function in a child with a prolonged suppurative cough, remains important. In Turkey, the most common causes of non-CF bronchiectasis are PCD and immunodeficiency, related to a high frequency of consanguinity.

Our objective was to evaluate the performance of matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) for identification of the Chryseobacterium and Elizabethkingia spp. isolated from pediatric patients at Hacettepe University Hospital using 16S rRNA gene sequencing as the gold standard and to determine the antimicrobial susceptibility patterns of the isolates and baseline characteristics of patients. All stored Chryseobacterium and Elizabethkingia spp. isolated from various clinical specimens (sputum, blood, and urine) of pediatric patients at Hacettepe University Hospital between 2012 and 2016 were included in this study. Minimum inhibitory concentrations of 10 antimicrobial agents were determined by Etest for all isolates. To determine the baseline characteristics of patients, medical records of all patients were retrospectively reviewed. In total, 18 isolates of Chryseobacterium spp. (16 C. indologenes, 2 C. gleum) and 5 isolates of Elizabethkingia spp. (3 E. meningoseptica, 2 E. anophelis) were identified by 16S rRNA sequencing. MALDI-TOF MS correctly identified 19 (82.6%) isolates to the species level. The quinolones (ciprofloxacin and levofloxacin), trimethoprim/sulfamethoxazole and piperacillin/tazobactam showed the highest spectrum of activity against the overall collection of isolates. Cystic fibrosis (CF) was the underlying disease in 81.8% of patients. To our knowledge, this study includes the largest number of Chryseobacterium spp. isolated from clinical specimens of pediatric patients in Turkey. In this study, we also report the first clinical isolate of E. anophelis in Turkey. Since, the majority of strains were isolated from patients with CF; larger, prospective clinical studies are needed to establish whether chryseobacteria could be considered as an emerging opportunistic pathogen in patients with CF.

BACKGROUND: Allergic bronchopulmonary aspergillosis (ABPA) in cystic fibrosis (CF) is characterized by destructive changes in the airways. Long-term treatment with oral corticosteroids is often required for repeated exacerbations. Because elevated total IgE is a cardinal abnormality of ABPA, omalizumab has been used sporadically to decrease corticosteroid dose or totally replace corticosteroids. OBJECTIVE: The aim of this report is to describe our experience with omalizumab treatment in patients with CF and ABPA. METHODS: We conducted a review of 6 CF patients with ABPA receiving omalizumab. All patients were treated with oral prednisolone and itraconazole. Omalizumab was started if the patient was not responding to steroid treatment, which was determined according to serum IgE levels and/or clinical findings or depending on if there were side effects caused by steroid treatment. RESULTS: The mean age of patients at the beginning of omalizumab treatment was 16.1 years. One patient had a new diagnosis of ABPA; however, the others had the first to third exacerbation when treated with omalizumab. The mean duration of ABPA by the time that treatment with omalizumab started was 13 ± 12.4 months (range = 2-29 months). With omalizumab treatment, IgE levels were decreased in all patients, and Aspergillus-specific IgE levels were decreased in 4 patients; however, FEV1(% predicted) improved only in 2 patients who had mild disease. Corticosteroids were reduced in the first, second, and third months of omalizumab treatment in 2, 1, and 3 patients, respectively. In 2 patients, steroid treatment was stopped. None of the patients suffered from side effects of omalizumab. The mean duration of omalizumab treatment was 12.5 months (range = 6-18 months). CONCLUSIONS: This study showed steroid-sparing effect, decreasing IgE levels, and improvement in respiratory symptoms in 6 CF patients with omalizumab treatment. Although this is a small sample of the population, omalizumab may be an alternative therapy for ABPA in CF patients who fail to respond to systemic corticosteroids or have serious adverse effects.
