Clinical and Prognostic Comparisons Between Invasive Pulmonary Aspergillosis With or Without Invasive Tracheobronchitis During Severe Influenza: a Retrospective Multicenter Cohort Study. (ITBA)

September 3, 2019 updated by: Centre Hospitalier Universitaire, Amiens
Invasive tracheobronchial aspergillosis (ITBA) is an uncommon, but severe clinical form of Invasive Pulmonary Aspergillosis (IPA) in which the fungal infection is entirely or predominantly confined to the tracheobronchial tree. In view of the limited data concerning critically ill patients admitted to the intensive care unit (ICU) with severe influenza associated with ITBA, the investigators decided to evaluate the differences between the clinical presentations of two invasive infections: ITBA and IPA without tracheobronchial involvement (No ITBA).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Invasive pulmonary aspergillosis (IPA) is a well-known complication in severely immunocompromised hosts patients. Recent evidence has identified others populations at risk for IPA, including those with chronic obstructive pulmonary disease (COPD) and advanced cirrhosis patients in intensive care units (ICUs). Moreover, Recently influenza has been identified as a new independent risk factor for IPA and IPA was described as an early complication of influenza. IPA groups different clinical presentations: the classical angio-invasive, the broncho-invasive form and the invasive tracheobronchitis aspergillosis form (ITBA).

ITBA is an infrequent clinical form of IPA with often a fatal outcome, in which Aspergillus infection involves entirely or predominantly the tracheobronchial tree. Early diagnosis of ITBA is based on bronchoscopy examination. Severe influenza is a life-threatening condition where IPA has been repeatedly reported. Little is known on severe influenza infection complicated with IPA and still less with ITBA. Current data on ITBA in critically ill patients hospitalized for severe influenza infection has only been described in single case reports. Because ITBA has been associated with a poorer prognostic than other forms of IPA, this retrospective study aimed to analyze diagnostic and prognostic differences between ITBA and IPA without tracheobronchial lesions, in critically ill patients with influenza infection hospitalized in ICU.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Patients eligible for inclusion were patients with a diagnosis of influenza confirmed by a positive influenza real time polymerase chain reaction (RT-PCR) from nasopharyngeal swab or bronchoalveolar lavage (BAL) fluid, with a concomitant diagnosis of proven or probable/putative IPA and the performing of a bronchoscopy

Description

Inclusion Criteria:

  • all ICU (Intensive care unit) patients
  • patients aged from 18 years and more
  • All patients hospitalized in ICU with a positive influenza RT-PCR extracted from the registry of the local virology department
  • patients with a diagnosis of influenza confirmed by a positive influenza real time polymerase chain reaction (RT-PCR) from nasopharyngeal swab or bronchoalveolar lavage (BAL) fluid, with a concomitant diagnosis of proven or probable/putative IPA and the performing of a bronchoscopy

Exclusion Criteria:

  • minor or adult with guardianship
  • absence of hospitalization in intensive care
  • influenza infection not confirmed by PCR

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change of management of ITBA diagnosis criteria
Time Frame: from day 0 to two weeks after the start of the study
Evolution of the diagnosis criteria of the ITBA
from day 0 to two weeks after the start of the study

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change of management of ITBA prognosis
Time Frame: from day 0 to two weeks after the start of the study
Evolution of ITBA prognosis
from day 0 to two weeks after the start of the study
