Objectives: Celiac disease is an autoimmune disorder that develops because of sensitivity to gluten-containing grains in genetically disposed individuals. Nasal mucociliary clearance is the most important protective factor that protects the upper and lower airways from foreign particulates. This study aimed to investigate the effect of celiac disease on nasal mucociliary clearance.
Methods: The study included patients with celiac disease and healthy children. Nasal mucociliary clearance time was measured using the saccharin test. The children's saccharin taste time was recorded in seconds.
Results: Overall, 65 children were included: 43 patients with celiac disease (66.2%) and 22 healthy children (33.8%). Of all the children, 42 (64.6%) were female, and the average age was 11.8 ± 4 years. Nasal mucociliary clearance time of patients with celiac disease (531 ± 155 s) was significantly prolonged in comparison to that of healthy children (448 ± 80 s) (p = 0.006). No relationships were found between the diagnosis age, celiac type, and histopathological phase and compliance with the gluten-free diet and nasal mucociliary clearance time of patients with celiac disease.
Conclusions: This study showed that nasal mucociliary clearance was prolonged in patients with celiac disease. A defect in nasal mucociliary clearance increases the risk of infection and inflammation in small airways. Studies reported a high prevalence of respiratory tract infection in patients with celiac disease, which was associated with malnutrition, vitamin deficiency, and hyposplenism. The findings of the present study indicated that impairment of nasal mucociliary clearance could play a role in the development of frequent lung infections in patients with celiac disease.

Primary ciliary dyskinesia (PCD, OMIM 244400) is a rare genetic disorder that affects motile cilia and is characterised by impaired mucociliary clearance of the airway epithelium, which results in chronic upper and lower airway infections. While short-read next-generation sequencing technology has been used for the genetic testing of PCD, its effectiveness is limited in identifying variants in the gene because of the nearly identical pseudogene As we confirmed that the gene was not expressed in airway cells, we obtained nasal mucosa biopsy specimens for total RNA sequencing (RNA-seq) with library enrichment using exome oligos. Among the 34 nasal samples from patients suspected of having PCD, three aberrant splicing patterns in were identified in two samples.

Alprazolam (Alp), a triazolobenzodiazepine, is widely prescribed for the treatment of sleep disorders, anxiety, and panic disorder. While oral administration remains the standard route, its slow onset of action has prompted interest in intranasal delivery as an alternative, offers the potential for direct drug delivery to the brain. This study aims to develop a fast-acting intranasal formulation of Alp (Alp-nd).

Intranasal drug administration offers a promising strategy for delivering combination antiretroviral therapy (cART) directly to the central nervous system to treat NeuroAIDS, leveraging the nose-to-brain route to bypass the blood-brain barrier. However, challenges such as enzymatic degradation in the nasal mucosa, low permeability, and mucociliary clearance within the nasal cavity must first be addressed to make this route feasible. To overcome these barriers, this study developed solid lipid nanoparticles (SLNs) with varying PEGylation levels (0 %, 5 %, 10 %, and 15 % w/w of PEGylated lipid), co-encapsulated with Elvitegravir (EVG) and Atazanavir (ATZ) as an integrase and protease inhibitor, respectively.

Background: Allergic rhinitis (AR) and acute non-allergic rhinosinusitis (ARS) often present with similar symptoms. While these are generally differentiated by history and occasionally by secretion cell counts, there are few data temporally comparing these conditions.
Methods: A prospective, observational study was conducted to assess nasal mucus properties, nasal obstruction, nasal secretion cells, and health related QOL during the acute phase (Day 5) and during a later phase of illness (Day 14/28).

The aim of this study was to develop a thermosensitive mucoadhesive (MA) in situ nasal gel for sumatriptan. A 3D response surface methodology (Design of Expert version 11) was employed to formulate nine different formulations. The Pluronic F-127 concentration (X1) and chitosan concentration (X2) were selected as independent factors.
