ABSTRACT
Background & objectives: Celiac disease (CD) is a genetic immune mediated disorder characterised by gluten intolerance. This single centre study, from north India was aimed to assess the clinical, serological and histological profile of CD in a large cohort of children and the changing trends in its presentation. Methods: A review of clinical details of CD children diagnosed between 2000 and 2019 and currently on follow up was performed. Information on demography, symptoms, associated conditions, serology, biopsy findings and gluten-free diet were analyzed. Results: The mean age (±standard deviation) of 891 children included in the study, at onset and at diagnosis was 4.0±2.7 and 6.2±3.1 yr, respectively. Growth faltering, abdominal pain, abdominal distension and diarrhoea were presenting symptoms in 70, 64.2, 61.2 and 58.2 per cent, respectively. A positive family history of CD was present in 14 per cent and autoimmune conditions in 12.3 per cent of children. Thyroid disorders were seen in 8.5 per cent of children and Type 1 diabetes mellitus (T1DM) in 5.7 per cent. The duration of breastfeeding had a weak positive correlation with age at onset and diagnosis of CD (P<0.001). Non-classical CD was significantly more common in children aged >10 yr and in those presenting after 2010 (P<0.01). T1DM and hypothyroidism occurred more frequently in non-compliant children. Interpretation & conclusions: This was the largest single centre study, pertaining to the presentation and follow up of CD in children. Infants and young children were more likely to present with classical symptoms of diarrhoea, abdominal distension and growth failure while older children presented with non-classical CD. There was a trend towards non-classical forms of CD in recent years.
ABSTRACT
Background & objectives: Clostridium difficile-associated disease (CDAD) remains an important nosocomial ailment. Antimicrobial therapy used for CDAD gives inconsistent results. This experimental study was planned to investigate the beneficial effects of Lactobacillus acidophilus and epidermal growth factor (EGF) for CDAD management. Methods: Among 10 groups of BALB/c mice (6 in each), group 1 served as controls receiving no inoculum. Animals in groups 2-10 received C. difficile, those in groups 3, 6 and 9 received L. acidophilus and those in groups 4, 7 and 10 received EGF after C. difficile inoculation. Animals in groups 5-7 were pre-treated with ampicillin and those in groups 8-10 with lansoprazole prior to C. difficile. The animals were killed and investigated for colonisation by C. difficile and toxin production, myeloperoxidase (MPO) activity and histopathology. Results: Colonisation by C. difficile was found to be significantly different (P<0.001) in the various groups. C. difficile toxin titres and MPO activity were significantly lower in animals given L. acidophilus and EGF after ampicillin (groups 6 and 7) and lansoprazole (groups 9 and 10). The severity of acute inflammation was also significantly less (P<0.05) in caecal and colonic segments of animals in groups 6 and 7 compared to those in group 5. Although the severity of acute inflammation was less in the caecal and colonic segment of animals in groups 9 and 10, the reduction was not significant compared to group 8. Interpretation & conclusions: Our findings showed that the administration of L. acidophilus and EGF reduced the severity of C. difficile infection in the experimental animals.
