Paediatr Respir Rev 2018 Sep 15. Epub 2018 Sep 15.

Medical Research Center, Research Affairs, Hamad Medical Corporation, PO Box 3050, Doha, Qatar; Pediatric Pulmonology, Sidra Medicine, PO Box 2699, Doha, Qatar. Electronic address:

Primary ciliary dyskinesia (PCD), also known as immotile-cilia syndrome, is a rare genetic disease that is inherited in an autosomal recessive manner. Several studies have explored certain aspects of PCD in the Arab world, yet much is still lacking in terms of identifying the different characteristics of this disease. In this paper, we aim to briefly cover those studies published about PCD in Arab countries, as well as to provide recommendations and guidelines for future studies. Read More

Mutations in C11orf70 Cause Primary Ciliary Dyskinesia with Randomization of Left/Right Body Asymmetry Due to Defects of Outer and Inner Dynein Arms.

Am J Hum Genet 2018 05;102(5):973-984

Department of General Pediatrics, University Children's Hospital Muenster, 48149 Muenster, Germany. Electronic address:

Primary ciliary dyskinesia (PCD) is characterized by chronic airway disease, male infertility, and randomization of the left/right body axis as a result of defects of motile cilia and sperm flagella. We identified loss-of-function mutations in the open-reading frame C11orf70 in PCD individuals from five distinct families. Transmission electron microscopy analyses and high-resolution immunofluorescence microscopy demonstrate that loss-of-function mutations in C11orf70 cause immotility of respiratory cilia and sperm flagella, respectively, as a result of the loss of axonemal outer (ODAs) and inner dynein arms (IDAs), indicating that C11orf70 is involved in cytoplasmic assembly of dynein arms.

C11orf70 Mutations Disrupting the Intraflagellar Transport-Dependent Assembly of Multiple Axonemal Dyneins Cause Primary Ciliary Dyskinesia.

Am J Hum Genet 2018 05;102(5):956-972

Genetics and Genomic Medicine Programme, University College London, UCL Great Ormond Street Institute of Child Health, London WC1N 1EH, UK. Electronic address:

Primary ciliary dyskinesia (PCD) is a genetically and phenotypically heterogeneous disorder characterized by destructive respiratory disease and laterality abnormalities due to randomized left-right body asymmetry. PCD is mostly caused by mutations affecting the core axoneme structure of motile cilia that is essential for movement. Genes that cause PCD when mutated include a group that encode proteins essential for the assembly of the ciliary dynein motors and the active transport process that delivers them from their cytoplasmic assembly site into the axoneme.

Primary ciliary dyskinesia (PCD) is a clinical rare peculiar disorder, mainly featured by respiratory infection, tympanitis, nasosinusitis, and male infertility. Previous study demonstrated it is an autosomal recessive disease and by 2017 almost 40 pathologic genes have been identified. Among them are the leucine-rich repeat- (LRR-) containing 6 (LRRC6) codes for a 463-amino-acid cytoplasmic protein, expressed distinctively in motile cilia cells, including the testis cells and the respiratory epithelial cells.

Introduction: Primary Ciliary Dyskinesia (PCD) describes a group of inherited disorders that result in abnormal ciliary motion leading to mucous stasis. Clinical features include almost universally otitis media with effusion (OME), particularly in infants. PCD patients provide us with a cohort of patients with OME that is not treated with ventilatory tube (VT) insertion as these have been shown to result in frequent complications including chronic otorrhoea, early extrusion and persistent perforation without significant improvement to hearing in the long term.

1 Department of Pediatrics, Rainbow Babies and Children's Hospital, Case Western Reserve University School of Medicine, Cleveland, OH, USA.

Primary ciliary dyskinesia (PCD) is an autosomal recessive disorder associated with severely impaired mucociliary clearance caused by defects in ciliary structure and function. Although recurrent bacterial infection of the respiratory tract is one of the major clinical features of this disease, PCD airway microbiology is understudied. Despite the differences in pathophysiology, assumptions about respiratory tract infections in patients with PCD are often extrapolated from cystic fibrosis (CF) airway microbiology. Read More

[Polypous pansinusitis with the deformation of the external nose in a 8 year-old child presenting with the primary ciliary dyskinesia syndrome].

Vestn Otorinolaringol 2017;82(5):61-63

А.I. Burnazyan State Research Centre, Russian Federal Medico-Biological Agency, Moscow, Russia, 123479.

This article reports a rare observation of the development of chronic polypous pansinusitis with deformation of the external nose in a 8 year-old child presenting with primary ciliary dyskinesia syndrome. The patient underwent multiple surgical interventions in the preceding period. The key argument in favour of the definitive diagnosis was the results of investigation of ciliated epithelium biopsy taken from the nasal cavity and bronchi in combination with the data obtained by diagnostic endoscopy of the nasal cavity and nasopharynx supplemented by computed tomography.

A targeted next-generation sequencing panel reveals novel mutations in Japanese patients with primary ciliary dyskinesia.

Auris Nasus Larynx 2018 Jun 19;45(3):585-591. Epub 2017 Sep 19.

Division of Personalized Medicine, Mie University Graduate School of Medicine, Tsu, Japan.

Objective: Primary ciliary dyskinesia (PCD) is a rare genetic disorder caused by functional impairment of cilia throughout the body. The early diagnosis of PCD is important for the prevention of long-term sequelae; however, this is often challenging because of the phenotypic heterogeneity of PCD and difficulty in genetic analysis. The majority of PCD patients in Japan are not diagnosed properly. Read More

Should transmission electron microscopy and ultrastructural cilia evaluation remain part of the diagnostic work-up for primary ciliary dyskinesia?

Ultrastruct Pathol 2017 Nov-Dec;41(6):386-389. Epub 2017 Sep 19.

b Cyprus International Institute for Environmental & Public Health , Cyprus University of Technology , Limassol , Cyprus.

The diagnostic work-up for primary ciliary dyskinesia (PCD) traditionally includes ciliary ultrastructural assessment using transmission electron microscopy (TEM). However, the identification of genetic variants of PCD that are missed by TEM, along with the development of novel diagnostic modalities for PCD that allow structural evaluation of cilia, such as immunofluorescence analysis and the increased availability of genetic testing, calls into questioning the contemporary role of TEM in the diagnostic work-up for PCD. In this manuscript, we describe the evidence for and against the use of TEM in PCD diagnosis, in light of recent developments of PCD. Read More

a Department of Paediatrics , Royal Brompton Hospital , London , United Kingdom.

Primary ciliary dyskinesia (PCD) is predominantly an autosomal recessively inherited condition that affects ~1 in 15,000 people. Diagnosis of PCD can be complex and is ordinarily based on the results of multiple investigations. These investigations include nasal nitric oxide, high-speed video microscopy, genotyping, and electron microscopy analysis of ciliary ultrastructure. Read More

a Department of Paediatrics , Royal Brompton Hospital , London , United Kingdom.

Primary Ciliary Dyskinesia (PCD) is a heterogeneous genetic condition characterized by dysfunction of motile cilia. Patients suffer from chronic infection and inflammation of the upper and lower respiratory tract. Diagnosis of PCD is confirmed by identification of a hallmark defect of ciliary ultrastructure or by identification of biallelic pathogenic mutations in a known PCD gene. Read More

b Department of Pediatrics and Marsico Lung Institute , University of North Carolina School of Medicine , Chapel Hill , North Carolina , USA.

Primary ciliary dyskinesia (PCD) is a genetic disorder causing chronic oto-sino-pulmonary disease. No single diagnostic test will detect all PCD cases. Transmission electron microscopy (TEM) of respiratory cilia was previously considered the gold standard diagnostic test for PCD, but 30% of all PCD cases have either normal ciliary ultrastructure or subtle changes which are non-diagnostic.

a Central EM-Lab, Department of Pathology , University Hospital Regensburg , Regensburg , Germany.

Routine diagnostic electron microscopy of primary ciliary dyskinesia (PCD) is based on the findings of ultrastructural defects of axonemal components. Assessment of the typical abnormalities can be enhanced by improving the sample preservation status using tannic acid (TA) as additive in the biopsy fixation or processing steps. Another option is the implementation of computer-assisted image analysis tools. Read More

Primary ciliary dyskinesia ciliated airway cells show increased susceptibility to biofilm formation.

Eur Respir J 2017 09 10;50(3). Epub 2017 Sep 10.

NIHR Southampton Biomedical Research Centre, University of Southampton and University Hospital Southampton NHS Foundation Trust, Southampton, UK

Non-typeable (NTHi) is the most common pathogen in primary ciliary dyskinesia (PCD) patients. We hypothesised that abnormal ciliary motility and low airway nitric oxide (NO) levels on airway epithelial cells from PCD patients might be permissive for NTHi colonisation and biofilm development.We used a primary epithelial cell co-culture model to investigate NTHi infection.

Primary Ciliary Dyskinesia Centre, NIHR Biomedical Research Centre, University of Southampton, Southampton, UK

Primary ciliary dyskinesia (PCD) is a rare genetic disease that affects the motility of cilia, leading to impaired mucociliary clearance. It is estimated that the vast majority of patients with PCD have not been diagnosed as such, providing a major obstacle to delivering appropriate care. Challenges in diagnosing PCD include lack of disease-specific symptoms and absence of a single, "gold standard", diagnostic test. Read More

Sinus bacteriology in patients with cystic fibrosis or primary ciliary dyskinesia: A systematic review.

Am J Rhinol Allergy 2017 Sep;31(5):293-298

Department of Otorhinolaryngology- Head and Neck Surgery and Audiology, Copenhagen University Hospital, Rigshospitalet, Copenhagen, Denmark.

Background: A correlation exists between the microbial flora of the upper and lower airways in patients with cystic fibrosis (CF) or with primary ciliary dyskinesia (PCD). The sinuses can function as a bacterial reservoir where gram-negative bacteria adapt to the airways and repeatedly are aspirated to and colonize the lungs according to the theory of the united (unified) airways. Whereas the pattern of bacterial flora in the lower airways has been extensively studied, the upper airways have drawn limited attention. Read More
