Summary
Immune Reconstitution Inflammatory Syndrome (IRIS) causes worsening symptoms despite HIV treatment due to restored immune responses. Understanding IRIS is crucial for HIV care providers as its incidence increases.
Area of Science:
- Infectious Diseases
- Immunology
- HIV Medicine
Background:
- Immune Reconstitution Inflammatory Syndrome (IRIS) presents as clinical deterioration despite effective antiretroviral therapy (ART) in HIV patients.
- IRIS arises from the restoration of pathogen-specific immune responses, often occurring during or after treatment of opportunistic infections.
- Risk factors include low CD4 counts, latent infections, and strong immune responses to highly active antiretroviral therapy (HAART).
Purpose of the Study:
- To summarize the diverse clinical presentations of IRIS.
- To discuss the diagnostic approaches for IRIS.
- To outline treatment strategies for IRIS and related immune syndromes.
Main Methods:
- Review of clinical presentations of IRIS.
- Analysis of diagnostic criteria for IRIS.
- Summary of current treatment modalities for IRIS.
Main Results:
- IRIS is characterized by paradoxical worsening of conditions due to immune system recovery.
- It can manifest as new syndromes or exacerbations of pre-existing infections.
- Associated conditions include autoimmune disorders and malignancies.
Conclusions:
- The incidence of IRIS is expected to rise with increased HAART availability.
- Most IRIS cases have a favorable prognosis, potentially indicating effective immune reconstitution.
- Early diagnosis and appropriate management are key for favorable outcomes in IRIS patients.

01:25Inflammatory Bowel Disease III: Crohn's Disease
Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...
01:12Chronic Inflammation: Introduction
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
01:29Inflammatory Bowel Disease IV: Pharmacological Management
Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.

01:26Inflammatory Bowel Disease I: Introduction
Inflammatory bowel disease is a group of chronic disorders marked by recurrent inflammation of the gastrointestinal tract due to an abnormal immune response against gut microflora. This leads to tissue damage. The two main forms are Crohn’s disease and ulcerative colitis.Crohn’s DiseaseCrohn’s disease is a relapsing inflammatory disorder that can affect any part of the GI tract, from the mouth to the anus. It involves all layers of the bowel wall (transmural) and shows “skip lesions” in which...
01:29Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel Disease...
01:24Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF
Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab (Humira),...
