About this study

We aim to describe the incidence of IVDA among patients presented with IE, describe their clinical, psychiatric and microbiological characteristics in comparison to non - IVDA, as well as the rate and types of complications and outcome, and responsiveness to medical treatment or surgical intervention.

Read the detailed description

Infective endocarditis (IE) is the infection of the endocardial surface of the heart mainly affecting the valves of the heart. It is still associated with very high morbidity and mortality all over the world despite various advances in diagnostic and treatment methods.

A few studies have shown that infective endocarditis represents less than 0.5% of adult cardiovascular admissions.While the overall incidence of IE has remained stable over the last several years, IE has increased in young people in parallel with injection drug use (IDU) behaviours and the growing opioid crisis.

According to recent guidelines , Intravenous (IV) drug use is considered a minor Duke criteria for the diagnosis of infective endocarditis.

Compared to the general population, intravenous drug abuse (IVDA) is associated with an up to 100-fold increased risk of IE through several mechanisms, including endothelial injury from injected particulate matter, direct injection of contaminated material, and drug-associated vasospasm leading to intimal damage and thrombus formation.

Also, IVDA is associated with HIV outbreaks, which is a well-known risk factor for IE. HIV-associated IE is associated with high rates of morbidity and mortality than non-HIV-associated IE.Because of its pathophysiology, IVDA-associated IE is more commonly right-sided. Beyond these known characteristics, however, literature on this topic is substantially limited, including the clinical and microbiological characteristics of these patients, rate and types of complications and outcomes.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The incidence of IVDA among IE patients

    Report the incidence of IVDA among IE patients, describe their clinical and microbiological characteristics comparison to the IE in non - IVDA.

    Measured: Baseline

  2. The complications of IVDA among IE patients

    Report the rates and types of complications

    Measured: Baseline

Secondary outcomes (4)

  1. The psychiatric characteristics of the addict group

    This will be done by psychiatric questionnaires:

    -Addiction Severity Index questionnaire to measure severity of the addiction on the patient

    Measured: Baseline

  2. The Withdrawal symptoms of the study group

    This will be done by psychiatric questionnaires:

    -Withdrawal symptoms questionnaire that occur to the patient after stop of the addiction

    Measured: Baseline

  3. The psychiatric characteristics of the study group

    This will be done by psychiatric questionnaires:

    -Symptom Check List 90 to measure other comorbidities

    Measured: Baseline

  4. The personality characteristics of the study group

    This will be done by psychiatric questionnaires:

    -Eysenck Personality questionnaire to measure personality.

    Measured: Baseline
