[Antibodies to Helicobacter pylori in gastric diseases]
Aim:
To study the count of antibodies to Helicobacter pylori (ABHP), their role in diagnosis and prognosis in gastric diseases (GD).
Material And Methods:
Enzyme immunoassay (kits from EcoLab and Vektor-Best, Russia) was used to measure serum levels of ABHP (IgG, IgA, IgM+IgG+IgA) in 46 GD patients.
Results:
It is shown that GD are characterized by a regular rise of serum ABHP which are serological markers of Helicobacter pylori infection. Percentage and absolute value of IgG-HP were the highest (78%, mean titer 1:604 vs control 1:110) as well as (IgM+IgG+IgA) antibodies to CagA-HP (approximately 82%, mean titer 1:160 vs. control 1:10); the level of IgA-HP was elevated by 39%, mean titer 1:442, control 1:120. Elevated levels of IgG-HP reflect intensity of inflammatory processes, IgA-HP--atrophic processes, IgM+IgG+IgA)-CagA-HP--proliferative processes in GD.
Conclusion:
High concentrations of ABHP are a diagnostic criterion of HP infection, reflect intensity of infectious, inflammatory, atrophic and proliferative processes in GD. Long-term persistence of elevated ABHP concentrations is one of the indications for application of antichelicobacter therapy in GD associated with HP while ABHP fall is an additional criterion of efficacy of the treatment.

Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
