Hypohistidinemia in juvenile rheumatoid arthritis

Insights

Plasma histidine levels were significantly lower in children with rheumatoid arthritis compared to healthy controls. This finding may impact nutritional strategies and treatment considerations for pediatric rheumatoid arthritis.

Area of Science:

  • Biochemistry
  • Pediatric Rheumatology
  • Nutritional Science

Background:

  • Rheumatoid arthritis (RA) is a chronic autoimmune disease affecting joints.
  • Nutritional status can influence inflammatory conditions like RA.
  • Histidine, an essential amino acid, plays roles in various physiological processes.

Purpose of the Study:

  • To investigate plasma histidine concentrations in children diagnosed with rheumatoid arthritis.
  • To compare histidine levels between pediatric RA patients and a control group.
  • To explore potential correlations between histidine levels and disease status or treatment.

Main Methods:

  • Blood samples were collected from 86 children with rheumatoid arthritis and a control group.
  • Plasma histidine concentrations were measured using a standardized biochemical assay.
  • Statistical analyses were performed to compare mean histidine levels between groups.

Main Results:

  • Children with rheumatoid arthritis exhibited significantly lower mean plasma histidine levels compared to controls.
  • No specific drug influences on plasma histidine were definitively established in this abstract.

Conclusions:

  • Reduced plasma histidine may be a characteristic biomarker in pediatric rheumatoid arthritis.
  • Further research is warranted to understand the implications of low histidine in pediatric RA.
  • Investigating histidine supplementation could be a future therapeutic avenue.

Acid Suppressive Drugs for Peptic Ulcer Disease: Histamine H2-Receptor Antagonists

Histamine H2 receptors, which are intricately located on the basolateral membrane of parietal cells, play a crucial role in modulating gastric acid secretion. When released from enterochromaffin-like cells, histamine engages H2 receptors, initiating the cyclic AMP (cAMP) pathway. In this pathway, adenylyl cyclase converts ATP into cAMP, elevating intracellular cAMP levels. The activation of protein kinase A follows, stimulating the proton pump. This stimulation prompts the secretion of hydrogen...

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...

Hypersensitivity Reactions: Delayed Hypersensitivity Reactions

Delayed-Type Hypersensitivity (DTH), or Type IV hypersensitivity, is a cell-mediated immune response. It occurs when T cells, rather than antibodies, mediate a reaction to specific antigens. It is characterized by a delayed onset (1-2 days) and involves the recruitment of macrophages to the inflammation site.The initiation of a DTH response begins with the sensitization of T cells. During this phase, which lasts at least 1-2 weeks, antigen-specific T cells are activated, clonally expanded, and...

Rheumatic Heart Disease I: Introduction

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Hypersensitivity Reactions: Immune-Complex Reactions

Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum sickness, a systemic...
