The clinical spectrum of SMA‐PME and in vitro normalization of its cellular ceramide profile

Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1941-1952, December 2022., 2022
Abstract Objective The objectives of this study were to define the clinical and biochemical spectrum of spinal muscular atrophy with progressive myoclonic epilepsy (SMA‐PME) and to determine if aberrant cellular ceramide accumulation could be normalized by enzyme replacement.

Overlap Syndrome in Respiratory Medicine: Asthma and Chronic Obstructive Pulmonary Disease [PDF]

Journal of Cardio-Thoracic Medicine, 2014
Asthma and chronic obstructive pulmonary disease (COPD) are highly prevalent chronic diseases in the general population. Both are characterized by similar mechanisms: airway inflammation, airway obstruction, and airway hyperresponsiveness. However, the distinction between the two obstructive diseases is not always clear.

CYFRA21-1 is a more sensitive biomarker to assess the severity of pulmonary alveolar proteinosis

BMC Pulmonary Medicine, 2022
Background Serum lactate dehydrogenase (LDH), carcinoembryonic antigen (CEA) and CYFRA21-1 are the commonly used biomarkers to identify patients with autoimmune pulmonary alveolar proteinosis (APAP).

Altered fecal microbiome and metabolome in adult patients with non-cystic fibrosis bronchiectasis

Respiratory Research, 2022
Background Emerging experimental and epidemiological evidence highlights a crucial cross-talk between the intestinal flora and the lungs, termed the “gut-lung axis”. However, the function of the gut microbiota in bronchiectasis remains undefined. In this

Laryngopharyngeal reflux in chronic obstructive pulmonary disease - a multi-centre study

Respiratory Research, 2020
Reflux of gastric content has been associated with recurrent exacerbations of chronic obstructive pulmonary disease (COPD). We aimed to assess the prevalence of laryngopharyngeal reflux (LPR) in COPD and if LPR is a contributing factor to clinically ...
