[Anemia during inflammatory processes: pathogenesis and clinical and morphological manifestations]
Arkhiv Patologii
|August 12, 2010
Summary
Anemia of inflammation (AI) is mediated by the hormone hepcidin, which limits iron availability to fight infection. This innate immunity mechanism results in reduced iron stores and hemosiderosis.
Area of Science:
- Immunology
- Hematology
- Endocrinology
Context:
- Anemia of inflammation (AI) is a complex condition impacting iron metabolism.
- Hepcidin, a key hormone, plays a central role in AI pathogenesis.
- Understanding AI is crucial for managing chronic inflammatory diseases.
Purpose:
- To review the current understanding of anemia of inflammation (AI).
- To elucidate the role of hepcidin in AI and innate immunity.
- To describe the clinical and morphological features of AI.
Summary:
- Proinflammatory cytokines stimulate hepcidin production by the liver.
- Hepcidin limits iron availability by degrading ferroportin, impacting enterocytes, macrophages, and hepatocytes.
- AI enhances resistance to infection by restricting microbial iron access, exemplifying innate immunity.
Impact:
- AI involves decreased functional iron stores and hemosiderosis in the liver and spleen.
- This review highlights AI as a critical component of the body's defense mechanisms.
- Further research into AI and hepcidin can lead to novel therapeutic strategies.

01:20Inflammatory Bowel Disease IV: Clinical Manifestations
Inflammatory bowel disease (IBD) encompasses two major chronic disorders—ulcerative colitis and Crohn’s disease—each characterized by relapsing episodes of gastrointestinal inflammation. Although they share certain clinical features, their patterns of involvement and manifestations differ in ways that aid diagnosis and guide management.Ulcerative ColitisUlcerative colitis is limited to the colon and rectum and involves continuous inflammation of the mucosal layer. The disease course is marked...
01:27Disorders of Erythrocytes
Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...
01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

01:24Chronic Kidney Disease II: Clinical Manifestations
Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...
01:30Inflammatory Bowel Disease II: Crohn's Disease
Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
