[Drug abuse and infection]
1Department of Anesthesiology, PUMC Hospital, CAMS and PUMC, Beijing 100730, China.
Summary
Drug abuse, including heroin and cocaine, impairs immune function and increases susceptibility to infectious diseases like AIDS. This drug-mediated immunomodulation, alongside lifestyle risks, heightens vulnerability to infections in drug users.
Area of Science:
- Immunology
- Infectious Diseases
- Addiction Medicine
Background:
- Drug abuse of substances like heroin, marijuana, and cocaine affects neuropsychological and pathophysiological responses.
- These drugs can impair immune functions through direct effects on immune cells or indirect mechanisms like HPA axis stimulation.
Purpose of the Study:
- To explore the link between addictive drug abuse and infectious diseases, focusing on immune system impairment.
- To understand how drug-induced immunomodulation contributes to disease progression in intravenous drug users (IVDUs).
Main Methods:
- Review of recent studies on drug abuse and infectious diseases.
- Analysis of proposed mechanisms of drug-induced immunomodulation.
- Examination of the correlation between IVDUs and human immunodeficiency virus (HIV) infections.
Main Results:
- Drug abuse alters abusers' responses and impairs immune functions.
- Drug-mediated immunomodulation is a key factor in AIDS progression among IVDUs.
- Drug abuse increases susceptibility to opportunistic infections and exposure to pathogens.
Conclusions:
- Drug abuse significantly compromises immune defenses, increasing vulnerability to infections.
- Both direct and indirect mechanisms contribute to drug-induced immunosuppression.
- Combined risks of increased pathogen exposure and weakened immunity elevate infection susceptibility in drug abusers.

01:15Drug Abuse and Addiction: Pharmacological Phenomena
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not necessarily...
01:29Pulmonary Tuberculosis I
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

01:02Prescription, Nonprescription and Orphan Drugs
Prescription drugs require a prescription from a medical practitioner and can only be obtained from a pharmacy. They have many applications, including treating pain, anxiety, and hypertension.
The misuse and addiction to prescription drugs is a growing problem that can affect people of all age groups, specifically teenagers. This can happen when prescription medications are used in ways not intended by the prescriber, such as taking someone else's prescription or using medication for...

01:20Infection
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

01:17Drug Dependence
Medications are typically administered to achieve therapeutic effects. Some drugs can modify an individual's mood and perception, frequently resulting in various enjoyable experiences. However, this can result in drug dependency, a condition marked by continuous drug use despite potential negative consequences. Drug dependency primarily falls into two categories: psychological and physical dependence. Psychological dependence occurs when the pleasurable feelings induced by the drug...
01:26Factors Affecting the Risk of Infection
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...
