Hypovitaminosis D: a novel finding in primary ciliary dyskinesia

Hypovitaminosis D: a novel finding in primary ciliary dyskinesia

BACKGROUND A relationship between low levels of serum vitamin D and respiratory infections has been established. No study has examined the frequency and clinical relevance of vitamin D deficiency in patients with primary ciliary dyskinesia (PCD). METHODS Vitamin D levels were measured in 22 PCD patients (7 females, 10.5 years, range, 2-34 years). In PCD, pulmonary function tests (PFTs), sputu...

Primary ciliary dyskinesia.

Primary ciliary dyskinesia (PCD) is a rare genetic condition that affects the ciliary function of the respiratory tract, sperm tail, cilia of the embryonic node, and fallopian tube. The condition is characterized by impaired ciliary action, leading to recurrent lower-respiratory-tract infections, bronchiectasis, rhino-sinusitis, otitis media, impaired fertility in women, and infertility in men....

Ciliary dyskinesias: primary ciliary dyskinesia in adults

Primary ciliary dyskinesia (PCD) is a genetic disorder of cilia structure and function, chronic infections of the respiratory tract, fertility problems and disorders of organ laterality. Establishing a definitive diagnosis can be challenging, requiring a compatible phenotype and detection of ciliary functional and ultra-structural defects, along with newer screening tools such as nasal nitric o...

Primary Ciliary Dyskinesia

Primary ciliary dyskinesia (PCD) is caused by ultrastructural ciliary defects that lead to abnormal ciliary beating and, subsequently, mucociliary dysfunction. PCD presents clinically with bronchiectasis, sinusitis, and, in up to 50% of cases, situs inversus. The ultrastructural defects of cilia are diverse but include in many cases outer and/or inner dynein arms. Recent advances have shown tha...
