Gastritis And Its Types

What’s Important?

 AMAG / EMAG against Type B Gastritis.  Selective forms of gastritis.

Gastritis                                     

• Acute
  • Infection-related; phlegmonous gastritis; emphysematous.
• Chronic
  • Syphilis; Autoimmune (Antibodies → Antigen); H. pylori; CMV (owl eye inclusion body); Herpes viruses; EBN; Mycobacteria; Syphilis; Most common antibody - H plus K plus ATPAIC; Second most frequent - Anti-intensive antibodies; Various kinds. 

Acute Gastritis

The most popular: NSAIDs Treatment: supportive (PPI/H2 blocker) Viruses > Bacteria > Fungi are the second most common causes.

Phlegmonous Gastritis

Alternatively known as suppurative gastritis; causative factors The most prevalent organisms are streptococci or E. coli. Patients with chronic debility or immunocompromised individuals are usually affected by an uncommon form of gastritis.
Features in clinical context
• Severe fever or pain in the abdomen
• The infection affects the muscle level, or lamina propria; the imaging may demonstrate the thickened stomach wall. Mucosa plays no role.
• connected to gas or pus-filled pockets; thicker stomach walls
Treatment options include: gastroplasty, early broad-spectrum treatment, antibiotics, vanco and piptaz. 

Emphysematous Gastritis

Bacteria that produce gas, such as S. aureus, E. coli, and Cl. perfringens  The death rate exceeds forty percent. There are gas pockets visible in the stomach wall.
Treatment options include: gastroplasty, early broad-spectrum treatment, antibiotics, vanco, and piptaz

Chronic Gastritis

Gastritis caused by the pylori virus; Chronic Atrophic Gastritis; Differential Forms; Collagenous; Lymphocytic/varioliform; Eosinophilic; Gastritis cystica profunda

H.Pylori Gastritis 

Chronic Atrophic Gastritis 

The Spectrum of AMAG and EMAG

• AMAG = autoimmune metaplastic atrophic gastritis
• EMAG = environmental metaplastic atrophic gastritis

Evaluation Of Chronic Gastritis              

• OGD: investigation of preference;
• Biopsy: five sites
• OLG - Operative Link for Gastritis Assessment; OLGIM - Operative Link for Gastritis Intestinal Metaplasia; 1 from Incisura; 2 from Antrum; 2 from body; B12 levels should be examined; increased risk of stomach
• A superior staging is OLGA.

Distinctive Forms Of Gastritis                                

Collagenous gastritis: adults get diarrhea, and children experience abdominal pain.  A condition in which the lamina subepithelial area exhibits enhanced collagen deposition  Biopsy reveals normal modules; endoscopy demonstrates mucosal modularity.

There are more than 20 microns of collagen.

Lymphocytic Gastritis 

OGD, or varioliform gastritis; • H pylori and celiac disease; • nodule formation and central atrophy.

• IEL in the propria lamina

Eosinophilic Gastritis

More than 20 Eosinophilic per hpf; more than 50% of patients have peripheral eosinophilia; antral region has greater edema; the patient may present with recurrent food infections in the esophagus; an obstructive presentation may arise.
