Highly active antiretroviral therapy (HAART) impacts cardiovascular health in human immunodeficiency virus (HIV)/AIDS patients differently worldwide. While reducing some conditions in developed nations, HAART may increase heart problems in developing countries due to limited access and nutritional factors.
Area of Science:
- Cardiology
- Infectious Diseases
- Public Health
Background:
- Highly active antiretroviral therapy (HAART) has profoundly influenced the cardiovascular health of individuals with human immunodeficiency virus (HIV)/AIDS.
- Cardiovascular manifestations, including cardiomyopathy and pericardial effusion, have seen shifts in prevalence globally.
- Disparities in HAART availability and the role of nutritional factors contribute to differing cardiovascular outcomes in developed versus developing countries.
Purpose of the Study:
- To analyze the impact of HAART on cardiovascular manifestations in HIV/AIDS patients.
- To compare cardiovascular disease prevalence and outcomes in developed and developing countries.
- To highlight the association between specific HAART regimens, lipodystrophy, and accelerated atherosclerosis.
Main Methods:
- Review of epidemiological data on cardiovascular manifestations in HIV/AIDS patients.
- Comparison of prevalence rates of conditions like cardiomyopathy and pericardial effusion before and after HAART implementation.
- Analysis of the relationship between HAART regimens, metabolic changes (lipodystrophy), and cardiovascular risk.
Main Results:
- A 30% reduction in cardiomyopathy and pericardial effusion prevalence in developed countries, linked to decreased opportunistic infections and myocarditis.
- A 32% increase in cardiomyopathy prevalence and elevated mortality from heart failure in developing countries.
- Certain HAART regimens, particularly those with protease inhibitors, are associated with lipodystrophy syndrome and increased cardiovascular events due to accelerated atherosclerosis.
Conclusions:
- HAART has a complex and geographically varied effect on cardiovascular health in HIV/AIDS patients.
- Limited HAART access and nutritional factors exacerbate cardiac issues in developing nations.
- Routine cardiac screening is crucial for HIV/AIDS patients on HAART, especially those with pre-existing cardiovascular risk factors.

Pulmonary Tuberculosis I
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.

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...
