Adverse Drug Reactions to Anti-TB Drugs in the Treatment of Latent Tuberculosis Infection

2017-10-23 20:44:13 | BioPortfolio


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).


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.

Medical and Biotech [MESH] Definitions

The dormant form of TUBERCULOSIS where the person shows no obvious symptoms and no sign of the causative agent (Mycobacterium tuberculosis) in the SPUTUM despite being positive for tuberculosis infection skin test.

Pathological conditions of the CARDIOVASCULAR SYSTEM caused by infection of MYCOBACTERIUM TUBERCULOSIS. Tuberculosis involvement may include the HEART; the BLOOD VESSELS; or the PERICARDIUM.

Tuberculosis of the brain, spinal cord, or meninges (TUBERCULOSIS, MENINGEAL), most often caused by MYCOBACTERIUM TUBERCULOSIS and rarely by MYCOBACTERIUM BOVIS. The infection may be limited to the nervous system or coexist in other organs (e.g., TUBERCULOSIS, PULMONARY). The organism tends to seed the meninges causing a diffuse meningitis and leads to the formation of TUBERCULOMA, which may occur within the brain, spinal cord, or perimeningeal spaces. Tuberculous involvement of the vertebral column (TUBERCULOSIS, SPINAL) may result in nerve root or spinal cord compression. (From Adams et al., Principles of Neurology, 6th ed, pp717-20)

Infection of the lymph nodes by tuberculosis. Tuberculous infection of the cervical lymph nodes is scrofula.

Infection of the LIVER with species of MYCOBACTERIUM, most often MYCOBACTERIUM TUBERCULOSIS. It is characterized by localized small tuberculous miliary lesions or tumor-like mass (TUBERCULOMA), and abnormalities in liver function tests.
