Summary
Haemophagocytic lymphohistiocytosis (HLH) is a severe immune disorder involving macrophage overactivation. Prompt diagnosis and immunochemotherapy are crucial for survival in this aggressive condition.
Area of Science:
- Immunology
- Hematology
- Genetics
Background:
- Haemophagocytic lymphohistiocytosis (HLH) is a life-threatening hyperinflammatory syndrome.
- It involves uncontrolled activation of macrophages and cytokine release.
- HLH can be primary (genetic) or secondary to other conditions.
Purpose of the Study:
- To define the characteristics of haemophagocytic lymphohistiocytosis.
- To highlight the importance of early recognition and treatment.
Main Methods:
- Review of clinical and pathological features of HLH.
- Analysis of genetic and acquired causes.
- Evaluation of treatment outcomes.
Main Results:
- HLH is characterized by persistent macrophage activation and phagocytosis of blood cells.
- Genetic mutations affecting lymphocyte cytotoxicity are implicated in primary HLH.
- Secondary HLH is associated with infections, autoimmune diseases, or malignancies.
Conclusions:
- HLH has a high fatality rate without timely intervention.
- Early diagnosis and prompt immunochemotherapy are essential for improving patient survival.

Lysosomal Hydrolases
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...
Hypersensitivity Reactions: Cytolytic Reactions
Type II hypersensitivity involves IgG and IgM antibodies targeting cell surface antigens, leading to cell destruction. This can occur through complement activation, antibody-dependent cell-mediated cytotoxicity (ADCC), or acting as opsonins for phagocytosis. When excessive, these reactions cause significant tissue damage.Drug-induced hemolytic anemia is a common example, where drugs like penicillin or cephalosporins bind to red blood cells, forming drug-protein complexes. These complexes...
Hepatitis
Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...
Regulation of Hematopoietic Stem Cells
All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...
Disorders of Hemostasis
Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.

Phagocytosis of Apoptotic Cells
Cells undergoing apoptosis form apoptotic bodies that must be removed immediately to prevent inflammation, autoimmune diseases, and necrosis. Phagocytosis is carried out by professional phagocytes such as macrophages or immature dendritic cells. Non-professional phagocytes such as epithelial cells and fibroblasts also take part in this process; however, they are not as effective as professional phagocytes.
Normal cells contain receptors that prevent them from being recognized by phagocytes.
