Infectious diseases in drug addicts

People with drug addictions have an increased risk of certain diseases. This is a consequence of the often very low hygienic level of their environment and the method of application (most often by injection). Social standards and health care are subordinated to the desire for another dose of the drug. Illegality pushes drug addicts to reuse some devices (needles).

Infections are a major aspect of drug harm. They arise as a result of:


 * neglect of the rules of asepsis in the administration of intravenous drugs;
 * sharing needles and syringes;
 * promiscuity motivated by prostitution or as a behavioral disorder;
 * non-compliance with basic hygiene habits;
 * aspirations for impaired consciousness;
 * immunosuppression of drugs (heroin, methadone ) or alcohol.

Etiology
There is a higher prevalence of resistant microorganisms in drug addicts due to frequent self-treatment with illegally acquired antibiotics. Insufficient nutrition (reduced appetite, vomiting, diarrhea, lack of funds ...) leads to a general weakening of immunity. Mental stress and strain during withdrawal symptoms also negatively affect the body's defenses. The most common infectious diseases in drug addicts are infectious hepatitis B, C (or D), HIV (and subsequent AIDS ) and infectious endocarditis.

Klinická manifestace

Diagnóza
False negativity cultures for self-treatment with illegally obtained antibiotics. Offer taking anti-HIV antibodies.

Diferenciální diagnóza
False seropositivity (VDRL, autoantibodies), fever from drug impurities, impaired consciousness from intoxication (may mimic neuroinfection), withdrawal ( vomiting and diarrhea during heroin withdrawal), pulmonary edema.


 * Therapy

Take into account antibiotic resistance, tolerance of analgesics and sedatives, take into account non-compliance with the treatment regimen and arbitrary premature termination of treatment.
