Adverse Drug Reactions to Antituberculosis Drugs in the Treatment of Latent Tuberculosis Infection in Korean Health Care Workers

The investigators aim to study the prevalence of adverse reactions of anti-tuberculosis (TB) drugs in latent tuberculosis infection (LTBI), and determine the risk factors of anti-TB drug-related toxicity in LTBI in Korean health care workers(HCWs).

Detailed Description

Further study details as provided by Hanyang University Hospital

This study is prospective study of newly diagnosed LTBI in HCWs at Hanyang University Hospital, a tertiary referral hospital in South Korea, between 2017 and 2018. This study aimed to identify the prevalence of adverse reactions of treatment regimen for LTBI. The diagnosis of LTBI was made on the basis of interferon-gamma releasing assay. Information on demographic characteristics, comorbidity and treatment outcomes was collated from questionnaires. Treatment regimen for LTBI was chosen by patients' preference among 3 months of INH(isoniazid) plus RFP(rifampin), 4 months of RFP and 9 months of INH. All PTB patients were observed 2 weeks after the initiation of medication, and monthly thereafter, and were asked about any drug side effects at these visits. Serious adverse drug reaction (ADR) was defined as any severe side effect that resulted in discontinuation or change (either temporally or permanently) of anti-TB medication, and/or directly resulted in hospitalization. Drug-induced hepatitis was defined as liver transaminases more than three times higher than the upper limit of normal in the presence of symptoms such as anorexia, nausea, vomiting, or abdominal pain, or transaminases more than five times the upper limit of normal without symptoms.

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

19 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

Study Population

Subjects diagnosed with latent tuberculosis infection (LTBI) using whole-blood interferon-r release assays in Korean health care workers.

Description

Inclusion Criteria:

  • 19 years or more
  • Identified latent tuberculosis infection (LTBI) in Korean health care workers, using whole-blood interferon-r release assays

Exclusion Criteria:

  • Subjects who do not want to participate the present study

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Latent tuberculosis infection
Identified subjects with latent tuberculosis infection (LTBI) using whole-blood interferon-r release assays. All enrolled subjects were treated with one of the recommended regimens for LTBI treatment: 9 months of isoniazid, 4 months of rifampin and 3 months of isoniazid plus rifampin. Blood, urine sampling, and monitoring frequencies of adverse reactions of anti-TB drugs were performed.

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
The numbers of adverse drug reactions (ADR) during LTBI treatment
Time Frame: one year
All events of adverse drug reactions (ADR) were reported using the clinical signs, symptoms, and liver chemistry at predefined intervals (two weeks after the initiation of anti-TB drugs, and monthly thereafter).
one year

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
The numbers of severe ADR during LTBI treatment
Time Frame: one year
Among all ADR, serious ADR was defined as any severe side effect that resulted in discontinuation or change (either temporally or permanently) of anti-TB drugs, and/or directly resulted in hospitalization. Drug-induced hepatitis was defined as liver transaminases more than three times higher than the upper limit of normal (γ-glutamyl transpeptidase (γ-GT) >69 U/L; serum glutamic oxaloacetic transminase (SGOT) >54 U/L; serum glutamic pyruvic transminase (SGPT) >60 U/L) in the presence of symptoms such as anorexia, nausea, vomiting, or abdominal pain, or transaminases more than five times the upper limit of normal without symptoms.

Study Major Dates

Study Start (ACTUAL)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 19, 2017

Primary Completion (ANTICIPATED)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
