OBJECTIVE: To analyze, using the medication review program, Revisem®, the prevalence of drug-related problems (DRP) in patients in the province of Valencia who were on active treatment with proton pump inhibitors (PPI) in 2022.
METHODS: Descriptive and retrospective observational study.
METHODS: The pharmacotherapeutic history of 295 patients was analyzed following the criteria proposed by the Pharmaceutical Care Network Europe, using the Revisem® digital platform of the Muy Ilustre Colegio Oficial de Farmacéuticos (MICOF).
RESULTS: The mean age of the patients was 81.8 ± 11.1 years and 66.4% were women. At least one DRP was detected in 97.3% of patients. 46.9% of the DRP analyzed were interactions, of which 29.7% involved a PPI, with omeprazole being the most frequent. DRPs with PPI are significantly related to certain patient conditions and pharmacological groups, such as female sex, age over 54 years and polypharmacy.
CONCLUSIONS: The application of the Revisem® digital platform allows the detection of a high prevalence of DRP at the provincial level. The application of new technological tools to detect the prevalence of DRP is essential to optimize patient treatments.

Helicobacter pylori infection is very common in the Spanish population and represents the main cause of chronic gastritis, peptic ulcer, and gastric cancer. The last iteration of Spanish consensus guidelines on H. pylori infection was conducted in 2016. Recent changes in therapeutic schemes along with increasing supporting evidence were key for developing the V Spanish Consensus Conference (May 2021). Fourteen experts performed a systematic review of the scientific evidence and developed a series of recommendations that were subjected to an anonymous Delphi process of iterative voting. Scientific evidence and the strength of the recommendation were classified using GRADE guidelines. An eradication therapy, when prescribed empirically, is considered acceptable when it reliably achieves, or preferably surpass, 90% cure rates. Currently, only quadruple therapies (with or without bismuth) and generally lasting 14 days, accomplish this goal in first- and second-line therapies. A non-bismuth quadruple concomitant regimen (proton pump inhibitor, clarithromycin, amoxicillin, and metronidazole) or a quadruple bismuth-based combination (proton pump inhibitor, bismuth, tetracycline, and metronidazole), are recommended as first-line regimens. Rescue therapies after eradication failure and management of H. pylori infection in peptic ulcer disease were also reviewed.

OBJECTIVE: An association between long-term use of proton pump inhibitors and the development of gastric neuroendocrine tumors has been reported, but it is still a subject of debate. The aims of the present study were to determine the presence of this association in a Mexican population and to identify the risk factors for developing gastric neuroendocrine tumors.
METHODS: A case-control study was conducted, in which the cases were patients with a histopathologic diagnosis of gastric neuroendocrine tumor and the controls were patients evaluated through upper endoscopy. The controls were paired by age, sex, and endoscopic examination indication. Proton pump inhibitor use was considered prolonged when consumption was longer than 5 years.
RESULTS: Thirty-three patients with gastric neuroendocrine tumor and 66 controls were included in the study. Eighteen (54.5%) patients in the case group were women, as were 39 (59%) of the patients in the control group. The median age of the patients in the case group was 55 years (minimum-maximum range: 24-82) and it was 54 years (minimum-maximum range:18-85) in the control group. A greater number of patients in the gastric neuroendocrine tumor group presented with gastric atrophy (p<0.0001) and autoimmune atrophic gastritis (p=0.0002), compared with the control group. No association between gastric neuroendocrine tumor and prolonged proton pump inhibitor use, sex, smoking, gastroesophageal reflux disease, Helicobacter pylori infection, diabetes mellitus, or autoimmune diseases was found in the univariate analysis.
CONCLUSIONS: The results of our study showed no association between proton pump inhibitor use for more than 5 years and the development of gastric neuroendocrine tumor. The presence of gastric atrophy and autoimmune atrophic gastritis was associated with gastric neuroendocrine tumor development.

Helicobacter pylori approximately infect 50% of Spanish population and causes chronic gastritis, peptic ulcer and gastric cancer. Until now, three consensus meetings on H.pylori infection had been performed in Spain (the last in 2012). The changes in the treatment schemes, and the increasing available evidence, have justified organizing the IVSpanish Consensus Conference (March 2016), focused on the treatment of this infection. Nineteen experts participated, who performed a systematic review of the scientific evidence and developed a series of recommendation that were subjected to an anonymous Delphi process of iterative voting. Scientific evidence and the strength of the recommendation were classified using GRADE guidelines. As starting point, this consensus increased the minimum acceptable efficacy of recommended treatments that should reach, or preferably surpass, the 90% cure rate when prescribed empirically. Therefore, only quadruple therapies (with or without bismuth), and generally lasting 14 days, are recommended both for first and second line treatments. Non-bismuth quadruple concomitant regimen, including a proton pump inhibitor, clarithromycin, amoxicillin and metronidazole, is recommended as first line. In the present consensus, other first line alternatives and rescue treatments are also reviewed and recommended.

OBJECTIVE: The chronic use of nonsteroidal anti-inflammatory drugs (NSAIDs) can cause complications in the gastrointestinal tract. The use of proton pump inhibitors (PPIs) is recommended in high-risk patients to prevent them.
OBJECTIVE: The aim of this article was to evaluate the gastroprotection measures taken in persons with chronic NSAID use.
METHODS: A descriptive cross-sectional study was conducted. The clinical records were reviewed of patients seen as outpatients at the Rheumatology Department over a 4-month period, choosing those with chronic NSAID use, and intentionally looking for gastroprotection measures according to the recommendations published by the American College of Gastroenterology.
RESULTS: A total of 417 patients (347 women; mean age: 48.12±14.2 years) were included. The most frequent diagnosis was rheumatoid arthritis (65%). Nine patients (2.1%) had a history of peptic ulcer, 48 (11.5%) patients were 65 years of age or older, 26 (6.2%) patients took NSAIDs and aspirin, and 130 (31.2%) took NSAIDs with steroids. Tests for Helicobacter pylori infection were done in just 53 cases, and there were positive results in only 9 (16%). Some risk for gastrointestinal toxicity was established in 211 cases and only 65 (30.8%) received gastroprotection. In contrast, 31 (15%) patients received gastroprotection when there was no indication for it.
CONCLUSIONS: Prophylaxis with PPIs in chronic NSAID users was inadequately employed. It was not prescribed in the majority of patients (69.2%) and it was used with no justification in others (15%).

This article summarizes the main studies in the field of non-variceal gastrointestinal bleeding reported in the last American Congress of Gastroenterology (Digestive Disease Week) in 2013. Some of these studies have provided new knowledge and expertise in areas of uncertainty. In this context and among other findings, it has been reported that the administration of a proton pump inhibitor (PPI) prior to endoscopy or the early performance of endoscopy-within 6 hours of admission in patients with upper gastrointestinal bleeding (UGIB) (or colonoscopy within 24 hours in patients with lower gastrointestinal bleeding)-does not improve the prognosis of the event. It has also been reported that oral administration of a PPI after endoscopic hemostasis may produce a similar outcome to that of intravenously administered PPI in patients with upper gastrointestinal bleeding (UGIB). In the field of endoscopic therapy, the use of radiofrequency ablation for antral vascular ectasia is of interest. Regarding UGIB and nonsteroidal antiinflammatory drugs (NSAIDs), new data confirm the risk of cardiovascular events by stopping treatment with acetylsalicylic acid (ASA) after an episode of UGIB, the increased risk of UGIB when associating gastrotoxic drugs, and the need to identify both the gastrointestinal and cardiovascular risks of each NSAID and coxib when prescribing these agents. Finally, there is evidence that both environmental and genetic factors are involved in individual susceptibility to gastrointestinal bleeding.
