About this study

OBJECTIVES: I. Determine the prevalence of nontuberculous mycobacteria in sputum cultures from patients with cystic fibrosis.

II. Compare the clinical course of patients with negative versus positive cultures.

Read the detailed description

PROTOCOL OUTLINE: Participants are screened for nontuberculous mycobacteria (NTM) with 3 sputum acid-fast bacilli smears and mycobacterial cultures, with speciation of positive cultures, collected over 1 year. Demographic data, diagnostic criteria, clinical measurements, and other respiratory pathogen data are collected using the Cystic Fibrosis Foundation Patient Registry Questionnaire.

NTM-positive patients (cases) matched with NTM-negative controls identified in screening are followed every 3 months for 15 months. Cases are evaluated for NTM burden during the first 3 months.

Appropriate therapy is offered to consistently NTM-positive cases. Lung transplant recipients are removed from study.

Questions about this trial

What is this clinical trial studying?

An observational study of Cystic Fibrosis and Atypical Mycobacterium Infection, run by National Center for Research Resources (NCRR).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Jun 2005. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00004296, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jun 2005.
