Background:
Tropical sprue (TS) and infection caused by Helicobacter pylori are a frequent cause of morbidity in the tropics. These disease entities, apart from having common regional distribution, probably also share hosts, sometimes exhibit symptom overlap, and very likely modify each other's course. The data supporting this association is scant and may testify to the association between them in causing human suffering.
Methods:
We enrolled 67 patients with dyspepsia, who also had an associated history suggestive of malabsorption (any two of the following: chronic diarrhea greater than four weeks and/or unintentional significant weight loss of >5% body weight over three months and/or nutritional deficiency of iron, B12, or folate in various proportions). They presented to the gastroenterology referral OPD of a tertiary care hospital in the northeastern region of India over a period of two and a half years. These patients were incorporated after informed consent and after fulfilling the inclusion and exclusion criteria. They initially underwent a battery of blood and stool tests to exclude other prevalent causes of malabsorption. This was followed by upper gastrointestinal endoscopy with additional rapid urease testing (RUT) wherever indicated, and mandatory biopsies were taken from the stomach corpus, antrum, and the second part of the duodenum.
Results:
A significant 53 of 67 patients were found to have H. pylori infection (as diagnosed by endoscopic findings, RUT, and histopathological examination of gastric biopsies) and concurrent features of TS on duodenal biopsies.
Conclusion:
Literature supporting such a close association between TS and H. pylori is scarce, and presentation of TS as dyspepsia is peculiar and unusual. This study offers new insights into the symptom overlap and coexistence of H. pylori infection and TS. In patients presenting with H. pylori infection and features of malabsorption, it is clinically prudent to evaluate for underlying TS to ensure a more inclusive and effective treatment approach.

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.

01:28Peptic Ulcer Disease II: Pathophysiology
Damaging agents such as Helicobacter pylori, gastric acid, pepsin, and nonsteroidal anti-inflammatory drugs (NSAIDs) can weaken the mucosal defense, allowing hydrogen ions to infiltrate back and harm epithelial cells.
01:30Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.

01:17Gastritis-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...
