Insights

Early diagnosis of primary ciliary dyskinesia (PCD) in newborns is possible through nasal biopsy. This aids in preventing severe respiratory complications like bronchiectasis.

Area of Science:

  • Genetics
  • Respiratory Medicine
  • Cell Biology

Background:

  • Primary ciliary dyskinesia (PCD) is a genetic disorder affecting ciliary structure and function.
  • Ciliated cells are crucial for mucus clearance in the respiratory tract and Eustachian tube.
  • Impaired clearance leads to conditions like sinusitis, recurrent pulmonary infections, bronchiectasis, and otitis media.

Observation:

  • Situs inversus is present in about 50% of PCD cases, forming Kartagener syndrome with bronchiectasis and sinusitis.
  • PCD is typically autosomal recessive, with rare X-linked inheritance.
  • Diagnosis relies on examining ciliary structure and function via microscopy.

Findings:

  • This study reports the early diagnosis of PCD in two newborns using nasal mucosal biopsy.
  • The newborns presented with prolonged respiratory distress and rhinorrhea.
  • Nasal biopsy proved effective for early PCD detection in neonates.

Implications:

  • Early diagnosis and management of PCD are vital to prevent bronchiectasis and lung function decline.
  • This diagnostic approach in newborns can lead to timely interventions.
  • Improved respiratory care strategies can be implemented for affected infants.

Mechanism of Ciliary Motion

The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...

Cystic Fibrosis: Pathogenesis

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Microtubules in Signaling

The primary cilium, made up of microtubules, acts as antennae on the cell surfaces for relaying external stimuli into the cells. These fine hair-like structures are present, generally one per cell. These are non-motile cilia in a 9+0 microtubules arrangement, where the central pair of microtubules are absent. The primary cilia arise from the basal body embedded in the cell membrane. Intraflagellar transport (IFT) carries requisite proteins from the cytoplasm to the cilium because the primary...

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
