Abstract
Primary ciliary dyskinesia (PCD) is a rare, genetically heterogeneous, motile ciliopathy, characterized by neonatal respiratory distress, recurrent upper and lower respiratory tract infections, subfertility, and laterality defects. Diagnosis relies on a combination of tests for confirmation, including nasal nitric oxide (nNO) measurements, high-speed videomicroscopy analysis (HSVMA), immunofluorescent staining, axonemal ultrastructure analysis via transmission electron microscopy (TEM), and genetic testing. Notably, there is no single gold standard confirmatory or exclusionary test. Currently, 54 causative genes involved in cilia assembly, structure, and function have been linked to PCD; this rare disease has a spectrum of clinical manifestations and emerging genotype-phenotype relationships. In this review, we provide an overview of the structure and function of motile cilia, the emerging genetics and pathophysiology of this rare disease, as well as clinical features associated with motile ciliopathies, novel diagnostic tools, and updates on genotype-phenotype relationships in PCD.

Changes in Sleep in Children and Adults with Cystic Fibrosis and Primary Ciliary Dyskinesia over Time and after CFTR Modulator Therapy. J Clin Med 2023; 12:7612. [PMID: 38137681 PMCID: PMC10744013 DOI: 10.3390/jcm12247612] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2023] [Revised: 12/02/2023] [Accepted: 12/09/2023] [Indexed: 12/24/2023] Open
Abstract
Cystic fibrosis (CF) and primary ciliary dyskinesia (PCD) are associated with sleep disturbances affecting quality of life (QOL) in both children and adults. However, little is known about the progression of these complaints over time, and the effect of CFTR modulator (CFTRm) therapies. Participants completed sleep quality (SDSC, PSQI) and quality of life questionnaires (PedQL, QOL-BE) as well as the Epworth sleepiness scale (ESS) at baseline and after 4 years. Medical records were reviewed for clinical data and correlations were sought between sleep, QOL, and clinical parameters. A total of 67 patients (33 pediatric), 37 pancreatic insufficient CF (CF-PI), 15 pancreatic sufficient CF (CF-PS), and 15 PCD patients, completed the study. In adults, global sleep quality decreased from 85.8% (76.2-90.5) to 80.9% (71.4-85.7); (p = 0.009). Analysis by disease cohort showed a significant deterioration only in the CF-PS group. In adults off CFTRm, sleep quality decreased from 85.7% (78.6-88.2) to 80.9% (71.4-87.3); (p = 0.021) and from 85.8% (76.2-92.9) to 76.2% (71.4-85.8); (p = 0.078) in people on CFTRm. Changes in sleep quality and changes in QOL over time were strongly associated with each other. In conclusion sleep quality deteriorates over time, correlates with QOL, and is driven primarily by adults and CF-PS patients. CFTRm has a possible effect on sleep initiation; however, results are mixed, and further long-term studies are required.

Abstract
Cystic fibrosis (CF) and primary ciliary dyskinesia (PCD) are genetic respiratory diseases featured by chronic upper and lower airway inflammation and infection, mainly due to impaired mucociliary clearance due to genetic mutations. Sleep is crucial to healthy children's normal physical and psychological development and has an important value in chronic respiratory diseases. Impaired sleep quality, such as sleep deprivation or insufficient sleep during the night, and sleep respiratory disorders (SRDs) are common in 5% to 30% of the general population. Sleep disruption leads to attention deficits, daytime sleepiness, fatigue and mood disorders and correlates to a worsened quality of life. Furthermore, sleep respiratory disorders (SRSs) are under-recognized comorbidities in CF and PCD patients. SRSs include a spectrum of symptoms ranging from primary snoring through upper airway resistance to obstructive sleep apnea (OSA), nocturnal hypoventilation and hypoxemia occurring in people with moderate to severe lung disease and damaging the disease-related outcomes and quality of life. Effective screening during sleep with polysomnography is very important for the timely initiation of efficacious treatments and to prevent worsened respiratory, metabolic and cardiovascular outcomes. However, the impact of SRDs on health and quality of life is still underinvestigated.

Abstract
OBJECTIVES The aim of this study was to summarize the otolaryngological manifestations amongst children with primary ciliary dyskinesia (cwPCD) to improve diagnosis, investigations and management amongst otolaryngologists. METHODS A retrospective review of primary ciliary dyskinesia (PCD) diagnoses at our institution over an 8-year period between January 2014 and October 2022 was conducted. Patient characteristics, diagnosis, otolaryngological symptomatology, treatment and outcomes were recorded. RESULTS 24 patients were identified. Thirteen patients (54%) had documented conductive hearing loss on audiological evaluation; with 11 (85%) requiring hearing aids. Six patients (25%) underwent middle ear ventilation tube (MEVT) insertion with 67% experiencing post-MEVT otorrhoea. Twenty children (83%) reported chronic nasal discharge however only 3 (13%) reported nasal obstruction. Nine patients (38%) had symptoms consistent with sleep disordered breathing with 79% of them requiring operative management with adenotonsillectomy. CONCLUSION Middle ear effusion is common amongst cwPCD and should be managed with conservative measures due to the significant burden of post-MEVT otorrhoea. Sinonasal symptoms rarely need surgical intervention. Many otolaryngological symptoms of PCD are often underreported, particularly sleep-disordered breathing. Paediatric PCD patients should be managed in a multidisciplinary team with routine and tailored therapies to manage all aspects of the condition.

Int J Mol Sci 2023; 24:ijms24065504. [PMID: 36982578 PMCID: PMC10052011 DOI: 10.3390/ijms24065504] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2023] [Revised: 03/07/2023] [Accepted: 03/11/2023] [Indexed: 03/17/2023] Open
Abstract
Sleep-disordered breathing (SDB) comprises different diseases characterized by abnormal respiratory patterns during sleep including obstructive sleep apnea. SDB prevalence and impact in patients with chronic respiratory infections have been only marginally studied. The purpose of this narrative review is to report the prevalence and impact of SDB in chronic respiratory infections, including cystic fibrosis (CF), bronchiectasis and mycobacterial infections, and explore the possible pathophysiological mechanisms. Common pathophysiological mechanisms, underlying SDB onset in all chronic respiratory infections, include inflammation, which plays a central role, chronic nocturnal cough and pain, excessive production of mucous plugs, presence of obstructive and/or restrictive ventilatory impairment, upper airways involvement, and comorbidities, such as alteration of nutritional status. SDB may affect about 50% of patients with bronchiectasis. The severity of the disease, e.g., patients colonized with P. aeruginosa and frequent exacerbators, as well as comorbidities, such as chronic obstructive pulmonary disease and primary ciliary dyskinesia, may impact SDB onset. SDB may also frequently complicate the clinical course of both children and adults with CF, impacting the quality of life and disease prognosis, suggesting that their routine assessment should be incorporated into the clinical evaluation of patients from the first stages of the disease regardless of suggestive symptoms, in order to avoid late diagnosis. Finally, although the prevalence of SDB in patients with mycobacterial infections is uncertain, extrapulmonary manifestations, particularly nasopharyngeal locations, and concomitant symptoms, such as body pain and depression, may act as atypical predisposing factors for their development.

Abstract
Objectives Disease-specific, well-defined and validated clinical outcome measures are essential in designing research studies. Poorly defined outcome measures hamper pooling of data and comparisons between studies. We aimed to identify and describe pulmonary outcome measures that could be used for follow-up of patients with primary ciliary dyskinesia (PCD). Methods We conducted a scoping review by systematically searching MEDLINE, Embase and the Cochrane Database of Systematic Reviews online databases for studies published from 1996 to 2020 that included ≥10 PCD adult and/or paediatric patients. Results We included 102 studies (7289 patients). 83 studies reported on spirometry, 11 on body plethysmography, 15 on multiple-breath washout, 36 on high-resolution computed tomography (HRCT), 57 on microbiology and 17 on health-related quality of life. Measurement and reporting of outcomes varied considerably between studies (e.g. different scoring systems for chest HRCT scans). Additionally, definitions of outcome measures varied (e.g. definition of chronic colonisation by respiratory pathogen), impeding direct comparisons of results. Conclusions This review highlights the need for standardisation of measurements and reporting of outcome measures to enable comparisons between studies. Defining a core set of clinical outcome measures is necessary to ensure reproducibility of results and for use in future trials and prospective cohorts.

Abstract
AIM We aimed to investigate sleep disturbances in children with cystic fibrosis (CF) and primary ciliary dyskinesia (PCD) and typically developing (TD) children during the COVID-19 pandemic. METHODS Primary care givers of children with CF and PCD aged 3-16 years were asked to enrol in the study. Primary care givers of TD children were included as control group. The Sleep Disturbance Scale for Children (SDSC) was used, and questions related to sleep habits during the pandemic were asked. Results of the three groups were compared. RESULTS Primary care givers of 33 children with CF, 16 children with PCD and 66 TD children were included in the study. There were no differences in terms of age and gender between the three groups. Changes in sleep patterns during the pandemic were more common among TD children and their families, with 75% of the children and 80% of their families sleeping later than before. The sleep initiation and maintenance disorder scores were higher in TD children (P = 0.001), whereas the sleep breathing disorder scores were higher in children with PCD (P = 0.001), and the sleep hyperhidrosis scores were higher in children with CF and PCD (P = 0.011). No relationships were found between sleep parameters and clinical findings of children with lung disease. CONCLUSIONS Children's sleep habits have changed during the pandemic. Children with chronic lung diseases and even TD children may experience sleep disturbances during this period.

Abstract
BACKGROUND Primary ciliary dyskinesia (PCD) patients have higher incidence of sleep disordered breathing which lead neurocognitive impairments such as attention-deficit/hyperactivity disorder (ADHD). It may effect academic performance of children and may cause impairment in emotional relationships. This study aim to evaluate hyperactivity and attention deficiency in PCD patients and investigate the relationship between sleep and hyperactivity and attention deficiency in PCD patients. METHOD Fifteen PCD patients aged 8-18 years and 31 age-matched healthy controls were compared. Ear, nose, and throat examination and home sleep testing were performed in PCD patients. Pediatric sleep questionnaire, Conners' Parents and Teacher scale and Stroop test were applied in both groups in order to investigate the relation between sleep disordered breathing and ADHD in PCD children. RESULTS PCD patients had chronic rhinosinusitis (100%), tonsillar hypertrophy (80%) and adenoidal hypertrophy (60%). FEF25-75 was low in pulmonary function test. Sixty percent of the PCD patients had mild obstructive sleep apnea syndrome in home sleep testing. Mean AHI was 1.54 ± 0.27. Compared with the controls PCD patients had higher PSQ scores. Hyperactivity scores on Conners' Parents scale and inattention findings in Stroop test were higher in PCD patients than the healthy controls (P < 0.05). CONCLUSION Most of PCD children had mild obstructive sleep apnea syndrome. Hyperactivity and inattention findings were higher in PCD patients. Sleep disordered breathing assessment should be a routine part of PCD patients management and these patients should be carefully monitored in terms of hyperactivity and inattention.

Primary ciliary dyskinesia (PCD) is an orphan disease (MIM 244400), autosomal recessive inherited, characterized by motile ciliary dysfunction. The estimated prevalence of PCD is 1:10,000 to 1:20,000 live-born children, but true prevalence could be even higher. PCD is characterized by chronic upper and lower respiratory tract disease, infertility/ectopic pregnancy, and situs anomalies, that occur in ≈50% of PCD patients (Kartagener syndrome), and these may be associated with congenital heart abnormalities. Most patients report a daily year-round wet cough or nose congestion starting in the first year of life. Daily wet cough, associated with recurrent infections exacerbations, results in the development of chronic suppurative lung disease, with localized-to-diffuse bronchiectasis. No diagnostic test is perfect for confirming PCD. Diagnosis can be challenging and relies on a combination of clinical data, nasal nitric oxide levels plus cilia ultrastructure and function analysis. Adjunctive tests include genetic analysis and repeated tests in ciliary culture specimens. There are currently 33 known genes associated with PCD and correlations between genotype and ultrastructural defects have been increasingly demonstrated. Comprehensive genetic testing may hopefully screen young infants before symptoms occur, thus improving survival. Recent surprising advances in PCD genetic designed a novel approach called "gene editing" to restore gene function and normalize ciliary motility, opening up new avenues for treating PCD. Currently, there are no data from randomized clinical trials to support any specific treatment, thus, management strategies are usually extrapolated from cystic fibrosis. The goal of treatment is to prevent exacerbations, slowing the progression of lung disease. The therapeutic mainstay includes airway clearance maneuvers mainly with nebulized hypertonic saline and chest physiotherapy, and prompt and aggressive administration of antibiotics. Standardized care at specialized centers using a multidisciplinary approach that imposes surveillance of lung function and of airway biofilm composition likely improves patients' outcome. Pediatricians, neonatologists, pulmonologists, and ENT surgeons should maintain high awareness of PCD and refer patients to the specialized center before sustained irreversible lung damage develops. The recent creation of a network of PCD clinical centers, focusing on improving diagnosis and treatment, will hopefully help to improve care and knowledge of PCD patients.

Abstract
AIM Sleep disordered breathing is a common problem in childhood that encompasses a spectrum of disorders extending from primary snoring to obstructive sleep apnea. This study aims to investigate the results of children undergoing evaluation with polysomnography in the sleep laboratory of a tertiary care hospital. MATERIAL AND METHODS Demographic and clinical features as well as sleep associated symptoms, scores of pediatric sleep questionnaire and Pittsburgh sleep quality index and polysomnography results are retrospectively evaluated. RESULTS Totally 131 patients were evaluated, of which 47.3% (n=62) were females and 52.7% (n=69) were males. Mean age was 101.85±59.15 months at the time of the study. Fifty percent (n=59) of patients complained of snoring and 43.7% (n=52) of patients complained of apnea during sleep. Mean obstructive hypopnea-apnea index was 5.12±11.72. Mean obstructive hypopnea-apnea index of snorers (6.93±13.53) was significantly higher than the mean obstructive hypopnea-apnea index of nonsnorers (2.32±5.43) (p=0.011). Mean obstructive hypopnea-apnea index of patients experiencing apnea during sleep (7.52±14.25) was significantly higher than the mean obstructive hypopnea-apnea index of the children who do not experience apnea (2.61±5.84) (p=0.008). No significant correlation was observed between obstructive hypopnea-apnea index and scores of pediatric sleep questionnaire and Pittsburgh sleep quality index. The prevalence of obstructive sleep apnea was 33.6% (n=44). Forty nine patients (39.8%) were treated after polysomnography. Frequently suggested treatment options were noninvasive mechanical ventilation (n=23, 46.9%), intranasal steroid (n=15, 30.6%), montelukast (n=11, 22.4%) and adenotonsillectomy (n=9, 18.4%). CONCLUSIONS Polysomnography is the gold standard in the diagnosis of sleep disordered breathing in children. Pediatricians should be able to recognize early signs and symptoms of sleep disordered breathing and refer the patients in risk to centers where evaluation with polysomnography is available.

Abstract
Few original studies have described the prevalence and severity of clinical symptoms of primary ciliary dyskinesia (PCD). This systematic review and meta-analysis aimed to identify all published studies on clinical manifestations of PCD patients, and to describe their prevalence and severity stratified by age and sex.We searched PubMed, Embase and Scopus for studies describing clinical symptoms of ≥10 patients with PCD. We performed meta-analyses and meta-regression to explain heterogeneity.We included 52 studies describing a total of 1970 patients (range 10-168 per study). We found a prevalence of 5% for congenital heart disease. For the rest of reported characteristics, we found considerable heterogeneity (I2 range 68-93.8%) when calculating the weighted mean prevalence. Even after taking into account the explanatory factors, the largest part of the between-studies variance in symptom prevalence remained unexplained for all symptoms. Sensitivity analysis including only studies with test-proven diagnosis showed similar results in prevalence and heterogeneity.Large differences in study design, selection of study populations and definition of symptoms could explain the heterogeneity in symptom prevalence. To better characterise the disease, we need larger, multicentre, multidisciplinary, prospective studies that include all age groups, use uniform diagnostics and report on all symptoms.

Abstract
INTRODUCTION Primary ciliary dyskinesia is an autosomal recessive genetic disorder leading to structural and/or functional abnormalities of motor cilia. Impaired mucociliary clearance is responsible for the development of a multi-organ disease, which particularly affects the upper and lower airways. STATE OF THE ART In adults, primary ciliary dyskinesia is mainly characterized by bronchiectasis and chronic ear and sinus disorders. Situs inversus is found in half of patients and fertility disorders are commonly associated. Diagnosis is based on specialized tests: reduced level of nasal nitric oxide concentrations is suggestive of primary ciliary dyskinesia, but only a nasal or bronchial biopsy/brushing with analysis of beat pattern by videomicroscopy and/or analysis of cilia morphology by electronic microscopy can confirm the diagnosis. However, the diagnosis is difficult to achieve due to the limited access to these specialized tests and to difficulties in interpreting them. Genetic tests are under development and may provide new diagnostic tools. Treatment is symptomatic, based on airway clearance techniques (e.g., physiotherapy) and systemic and/or inhaled antibiotics. Prognosis is related to the severity of the respiratory impairment, which can be moderate or severe. PERSPECTIVES AND CONCLUSIONS Diagnosis and management of primary ciliary dyskinesia remain poorly defined and should be supported by specialized centers to standardize the diagnosis, improve the treatment and promote research.

Abstract
Insomnia, poor sleep quality and short sleep durations are the most common problems seen in cancer patients. More studies are needed about sleep disorders in cancer patients. In our study, we aimed to investigate the prevalence of sleep disorders and the impact of these problems on the quality of life in cancer patients. Pittsburgh Sleep Quality Index (PSQI) was given to a total of 314 patients. The psychometric evaluation of the Turkish version of PSQI in cancer patients revealed that 127 (40.4%) patients had global PSQI scores >5, indicating poor sleep quality. There was no statistically significant relationship between PSQI scores and sexuality, marital status, cancer stage and chemotherapy type (P > 0.05); while the patients with bone and visceral metastasis had much lower PSQI scores (P = 0.006). Patients with Eastern Cooperative Oncology Group performance scores of 3 or more had also significantly lower PSQI scores (P = 0.02). In conclusion, PSQI questionnaire may be used to evaluate the sleep disorders in cancer patients. Consistent use of multi-item measures such as PSQI with established reliability and validity would improve our understanding of difficulties experienced by cancer patients with chronic insomnia.

Abstract
Primary ciliary dyskinesia (PCD) is a rare autosomal recessive disorder with defective structure and/or function of motile cilia/flagella, causing chronic upper and lower respiratory tract infections, fertility problems, and disorders of organ laterality. Diagnosing PCD requires a combined approach utilizing characteristic phenotypes and complementary methods for detection of defects of ciliary function and ultrastructure, measurement of nasal nitric oxide and genetic testing. Currently, biallelic mutations in 31 different genes have been linked to PCD allowing a genetic diagnosis in approximately ~ 60% of cases. Management includes surveillance of pulmonary function, imaging, and microbiology of upper and lower airways in addition to daily airway clearance and prompt antibiotic treatment of infections. Early referral to specialized centers that use a multidisciplinary approach is likely to improve outcomes. Currently, evidence-based knowledge on PCD care is missing let alone management guidelines. Research and clinical investigators, supported by European and North American patient support groups, have joined forces under the name of BESTCILIA, a European Commission funded consortium dedicated to improve PCD care and knowledge. Core programs of this network include the establishment of an international PCD registry, the generation of disease specific PCD quality of life questionnaires, and the first randomized controlled trial in PCD.

Abstract
BACKGROUND AND OBJECTIVE Sleep-disordered breathing (SDB) may develop in primary ciliary dyskinesia (PCD), leading to these diseases worsening one another. METHODS Sixteen stable PCD patients (4.9-17.2 years) and 42 controls underwent overnight respiratory polysomnography (rPSG) and Sleep Disturbances Scale for Children (SDSC). In PCD we assessed nasal endoscopy, pulmonary function tests and chest high-resolution computed tomography (HRCT). RESULTS Compared with controls, PCD had higher obstructive apnoea (4.7 vs 0.2, P < 0.001), central apnoea (0.8 vs 0.2, P < 0.001), hypopnoea (1.8 vs 0.2, P < 0.001), apnoea-hypopnoea (7.8 vs 0.6, P < 0.001), oxygen desaturation indexes (ODI; 0.7 vs 0.2, P = 0.002), and mean oxygen desaturation (4% vs 1%, P < 0.001), while mean and nadir oxygen saturation (97.1% vs 98.1, P < 0.001) (93% vs 97.2%, P < 0.001) were lower, respectively. In PCD, SDSC was unrelated to rPSG (P > 0.05), with total score and subscores of disorders in initiating and maintaining sleep, and sleep-wake transition lower than controls. PCD patients had chronic rhinosinusitis (100%) and adenoidal hypertrophy (50%). Total HRCT score was 7 (range 0-14). ODI correlated with functional residual capacity (r = 0.8, P = 0.02), total HRCT (r = 0.6, P = 0.03) and peribronchial thickening scores (r = 0.7, P = 0.02). Oxygen saturation was associated with bronchiectasis severity score (r = -0.6, P = 0.02). CONCLUSIONS PCD's parents may underestimate SDB. As nocturnal desaturation is associated with lung function and structure abnormalities, SDB may significantly contribute to pulmonary morbidity.

Abstract
Primary ciliary dyskinesia (PCD) leads to recurrent/chronic respiratory infections, resulting in chronic inflammation and potentially in chronic pulmonary disease with bronchiectasis. We analyzed longitudinal data on body length/height and body mass index (BMI) for 29 children and young adults with PCD aging 1.5-24 years (median, 14.5) who had been diagnosed at the age of 0.5-17 years (median, 8). Of these, 10 carried pathogenic mutations in either DNAH5 or DNAI1. In children with PCD, body length/height progressively decreased from +0.40 ± 0.24 SDS (the 1st birthday), +0.16 ± 0.23 SDS (3 years old), and -0.13 ± 0.21 SDS (5 years old) to -0.54 ± 0.19 SDS (7 years old; P = 0.01 versus 0), -0.67 ± 0.21 SDS (9 years old; P = 0.005 versus 0), -0.52 ± 0.24 SDS (11 years old; P = 0.04 versus 0), and -0.53 ± 0.23 SDS (13 years old; P = 0.03 versus 0). These results reflect low growth rates during the childhood growth period. Thereafter, heights stabilized up to the age of 17 years. The growth deterioration was not dependent on sex or disease severity but was more pronounced in DNAH5 or DNAI1 mutation carriers. BMI did not differ from population standards, which suggests that nutritional deficits are not the cause of growth delay. We conclude that PCD leads to chronic deprivation with significant growth deterioration during childhood.
