Reducing upper digestive bleeding risk in patients treated with direct oral anticoagulants and concomitant infection with

The Effect of Direct Oral Anticoagulants on Gastric Mucosa and Helicobacter Pylori Prevalence in Dyspeptic Patients: A Retrospective Cross-Sectional Study

Background and aim Although direct oral anticoagulants (DOACs) are widely used and their side effects related to bleeding at various body sites have been well studied in the literature, less is known about their local impact on gastric mucosa. Some studies suggest that the higher risk of gastrointestinal (GI) bleeding associated with DOACs may be due to their direct local anticoagulant effects on the gastric mucosa. In this study, we aim to evaluate whether this potential local effect has a favorable outcome on the gastric mucosa and the prevalence of Helicobacter pylori (HP).  Materials and methods A total of 125 patients with dyspepsia were included in the study. Sixty patients who had been using a DOAC for at least one month were classified as the "DOAC group," while 65 patients who had not used DOACs were designated as the "control group." Demographic, laboratory, and pathological findings for these patients were retrospectively analyzed from their medical files. Results Patients in the DOAC group were significantly less likely to have antral gastritis (AnG) (p = 0.028), while the frequencies of HP and atrophic gastritis (AtG) were similar between the two groups. Although not statistically significant, the DOAC group showed fewer instances of intestinal metaplasia (IM) and a higher number of upper GI ulcers. Patients who had been using DOACs for more than 12 months had increased incidences of IM, upper GI ulcers, AnG, and HP compared to those who had been using DOACs for 12 months or less. The Rivaroxaban subgroup showed significantly lower HP positivity compared to patients using other DOACs (p = 0.042). Among all subgroups, the Rivaroxaban group had the lowest frequency of AnG (p = 0.024). Conclusion While DOACs seem to prevent AnG, HP, and IM at their early use stages, unfavorable gastric mucosa manifestations might increase with prolonged use. Higher upper GI ulcer prevalence is another controversial result of this issue. Rivaroxaban shines amongst other DOACs with its lesser HP and AnG association. These exciting findings should be supported by randomized controlled trials with large patient populations.

Peri-Ulcerative Mucosal Inflammation Appearance is an Independent Risk Factor for 30-Day Rebleeding in Patients with Gastric Ulcer Bleeding: A Multicenter Retrospective Study

Aim

The aim of this study was to identify clinical endoscopic indicators related to peri-ulcerative mucosal inflammation and to analyze whether the degree of peri-ulcerative mucosal inflammation appearance is an independent risk factor for gastric ulcer rebleeding.

Methods

We conducted a retrospective study that included patients with gastric ulcer bleeding who were hospitalized at three medical centers in China from January 1, 2016 to December 31, 2019. Ulcer rebleeding that occurred within 30 days of successful initial hemostasis was analyzed to determine whether this event was related to the degree of peri-ulcerative mucosal inflammation appearance or other mucosal inflammation-related factors.

Results

We enrolled 1111 patients and determined that GBS-Rebleeding-ROC (P<0.001), age (P=0.01), use of NSAIDs (P=0.001), bile reflux (P<0.001), and Helicobacter pylori (P<0.001) are all risk factors for peri-ulcerative mucosal inflammation appearance. Through multivariate analysis, we determined that severe peri-ulcerative mucosal inflammation appearance (P=0.002) was an independent risk factor for ulcer rebleeding within 30 days. Finally, we developed a risk assessment model using factors associated with mucosal inflammation that may be useful for early prediction of rebleeding.

Conclusion

The risk factors for peri-ulcerative mucosal inflammation appearance were identified. Severe peri-ulcerative mucosal inflammation appearance is an independent risk factor for ulcer rebleeding.

Benefits of crenotherapy in digestive tract pathology (Review)

Balneotherapy, a branch of physical and rehabilitation medicine using the natural factors of balneal resorts for therapeutical purposes to modulate the symptoms of numerous diseases, represents a non-pharmaceutical therapeutic alternative, easily accepted by patients and used both preventively and curatively. Crenotherapy, a branch of balneotherapy, is the method in which mineral waters are used as a therapeutic internal cure by ingestion. This procedure is performed in spa resorts (where these natural resources exist), and the ingestion of mineral water takes place at the source (spring), in the quantities recommended by the medical rehabilitation physician, according to specific regimens for the condition to be treated. Depending on their physical and chemical composition, the therapeutic mineral waters fall into several categories, having clear indications for certain pathologies. Hypotonic, isotonic, or slightly hypertonic mineral waters are recommended in diseases of the digestive tract and hepatobiliary conditions. Over time, studies have been conducted to determine the effect of these types of treatments, highlighting the complex influence of crenotherapy on the gastrointestinal tract, with favorable results, therefore the use of mineral water intake in various pathologies being recommended. The current review focuses on the existing literature data and refers to the main progress made in understanding the benefit, indications, and crenotherapy procedures in the management of gastrointestinal disorders.
