Summary
Psoriasis in HIV patients presents unique challenges due to immune dysregulation. Highly active antiretroviral therapy (HAART) improves HIV-associated psoriasis, but careful management of conventional and biological treatments is crucial.
Area of Science:
- Dermatology
- Immunology
- Infectious Diseases
Background:
- Psoriasis is a chronic T-cell-mediated autoimmune skin disease.
- The interplay between psoriasis and Human Immunodeficiency Virus (HIV) infection requires further elucidation.
- Understanding immune dysregulation in HIV is key to understanding HIV-associated psoriasis.
Purpose of the Study:
- To clarify the pathogenesis of psoriasis in the context of HIV infection.
- To discuss the diagnostic challenges posed by HIV-associated psoriasis.
- To review management strategies for HIV-associated psoriasis.
Main Methods:
- Review of current literature on psoriasis and HIV.
- Analysis of T-cell subsets, autoimmunity, and genetic factors.
- Evaluation of clinical presentations and diagnostic clues.
Main Results:
- HIV-associated psoriasis can mimic other skin conditions, with variants like Reiter's syndrome indicating immunodeficiency.
- Highly active antiretroviral therapy (HAART) generally improves HIV-associated psoriasis.
- Conventional systemic treatments may require dose adjustments or be contraindicated.
Conclusions:
- Insights into T-cell subsets and immune dysregulation help understand HIV-associated psoriasis.
- Accurate diagnosis is essential, considering mimics of psoriasis in HIV patients.
- While HAART is beneficial, novel biological treatments show promise for HIV-associated psoriasis management.

01:20COPD: Pathogenesis and Clinical Features
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

01:20Asthma: Pathogenesis and Management
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

01:23Genital Herpes
Genital herpes is a sexually transmitted infection primarily caused by herpes simplex virus type 2 (HSV-2), though herpes simplex virus type 1 (HSV-1) is increasingly implicated in genital infections, particularly among younger populations. Transmission occurs mainly through sexual contact, with asymptomatic viral shedding serving as a major route of spread. This characteristic makes HSV-2 difficult to control at a population level, as individuals may unknowingly transmit the virus even in the...
01:27Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
01:26Sexually Transmitted Infections
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
01:28Herpes
Herpes simplex type 1 (HSV‑1) is a widespread pathogen responsible for orolabial lesions. It is an enveloped, double-stranded DNA (dsDNA) virus belonging to the family Herpesviridae. Once the virus infects a host cell, its double‑stranded DNA genome is delivered into the nucleus, where a coordinated cascade of immediate‑early, early, and late gene expression directs viral DNA replication, structural protein synthesis, and virion assembly. After primary infection of epithelial cells, HSV-1...
