A Retrospective, Blinded Validation of a Host-response Based Diagnostics (PATHFINDER)

March 6, 2016 updated by: MeMed Diagnostics Ltd.

A Retrospective, Blinded Validation Study to Assess the Accuracy of a Host-response Based Diagnostics for Distinguishing Between Bacterial and Viral Etiologies in Pediatric Patients With an Acute Febrile Disease

This is a retrospective, blinded, external validation study of a novel in-vitro diagnostic (IVD) assay that will include samples that were previously collected from febrile pediatric patients. The investigated assay measures the levels of a few host-related, blood-based, bio-markers that will be integrated into a single score. Based on this score, each patient will be classified into one of three categories: (i) bacterial immune response, (ii) viral immune response, and (iii) marginal immune response. The assay prediction and the patient diagnosis will than be unveiled and compared to determine their level of concordance.

Probability Sample

Study Population

The study population will include patients aged 1 month to 18 years of age that were sampled both during emergency department (ED) visit or during hospitalization stay and were diagnosed with an acute infectious disease or a non-infectious disease. All samples are expected to fall into one of the following categories:

  1. Patients with an acute bacterial infection
  2. Patients with an acute viral infection
  3. Patients with an acute mixed co-infection (bacterial and viral)
  4. Patients with a non-infectious disease (control group)

Description

Inclusion Criteria:

The infectious disease samples should also fulfill the following criteria:

  • The patient had a peak temperature ≥38°C (AND)
  • Symptoms initiated ≤ 7 days before sampling

The non-infectious disease control group will include:

  • Patients with a non-infectious disease

Exclusion Criteria:

  • Another infection episode during the last 3 weeks before sampling
  • Congenital immune deficiency (CID)
  • A proven or suspected HIV-1, HBV, HCV infection
  • Active hematological malignancy
  • Current treatment with immune-suppressive or immune-modulating
  • Other illnesses that affect life expectancy and/or quality of life

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The sensitivity and specificity of the assay in differentiating between bacterial and viral etiology of patients with an acute febrile disease

Time Frame
The sensitivity and specificity of the assay in differentiating between infectious and non-infectious disease etiology.
Time Frame: 0-7 days after the initiation of symptoms
We will evaluate the assay using the accuracy measures sensitivity and specificity of differentiating between infectious and non-infectious disease etiology in pediatric patients aged 1 month to 18 years.
0-7 days after the initiation of symptoms
