Brief Summary

The management of respiratory infections accounts for a large proportion of winter activity in paediatric wards. The main pathologies are bronchiolitis, affecting infants under the age of 2. Today, the reference method for diagnosing respiratory pathogen infections is nasopharyngeal aspirate (NPA), performed by paramedical staff. However, this technique is invasive and traumatic for paediatric patients. During the SARS-CoV-2 pandemic, salivary sampling was used on a large scale in the paediatric population, and showed good concordance with reference samples, as well as better tolerance/acceptability. The aim of the PreSaP (Paediatric Saliva Sampling) study is to assess the diagnostic capabilities of saliva samples¹ . This will be a monocentric, intra-individual, randomised study involving 502 children using the results of nasopharyngeal aspirates as the gold standard. We will also evaluate the time required to take nasopharyngeal aspirates and saliva samples in order to examine any difficulties associated with the two sampling methods. Although the results of our study report few diagnostic errors, they would justify the use of saliva sampling in routine care to reduce stressful and painful factors, and thus contribute to the well-being of infants and children. Saliva sampling could improve acceptance by the child and those around him, avoiding a less negative experience while guaranteeing a reliable diagnosis of respiratory pathogens. This new technique should also encourage the active involvement of all those involved in care.

Outcome Measures

Primary Outcomes (1)

  • Number of patient with a detection of respiratory pathogens

    This intra-individual trial (cross-over trial where two samples are taken from each child) aims to assess the ability of a test to detect respiratory pathogens from a saliva sample, using nasopharyngeal aspiration (NPA) as the gold standard.

    Day 1

Study Arms (2)

Standard arm with nasopharyngeal suction

ACTIVE COMPARATOR

This stand sample is the current gold standard for collecting winter virii in paediatrics. It consists of aspirating serosities via a nasopharyngeal device.

Diagnostic Test: The aim is to compare the effectiveness of virological and bacterial detection between two sampling methods

Experimental arm with nasopharyngeal swab

EXPERIMENTAL

This experimental sample will consist of inserting a weighted dummy into the oral cavity, in order to obtain a sample of the child's saliva and compare it with the standard sample.

Diagnostic Test: The aim is to compare the effectiveness of virological and bacterial detection between two sampling methods

Interventions

The nasopharyngeal swab and the buccal swab will be taken separately as a cross over with randomisation carried out to allow a different order for each patient. The collection time, the quantity of virus, the quality of the sample and the human intervention will be quantified.The pain and comfort of both carers and children will be assessed.
