Resources utilization and analysis of inpatients with NSAID related peptic ulcer

Chou, Yu-chi 13 July 2009 (has links)
Nonsteroidal anti-inflammatory drugs (NSAIDs) are one of the most frequently prescribed classes of drugs worldwide. Due to their excellent effects for analgesic, anti-inflammatory and antipyretic, most elder population used frequently for osteoarthritis. Gastrointestinal symptoms and ulceration associated with NSAIDs are common. Such ulcers may cause pain, bleeding, or perforation. It leads to other medical problems. The aim of this study was to examine the utilizations of medical resources associated with inpatients with NSAID related peptic ulcer disease and compared to non-NSAID related peptic ulcer disease. The study used the database from a teaching hospital in southern Taiwan. Inpatients who were identified ICD-9 CM codes as peptic ulcer diseases from January 1st of 2008 to December 31 of 2008 were included in this study. We also examined the indications for usage of NSAIDs, the date of prescription before the index date. The results showed 17.6% of inpatients with peptic ulcer disease related to NSAIDs. Inpatients with NSAIDs related peptic ulcer disease compared with inpatients with non-NSAIDs related peptic ulcer disease had significant difference in age and comorbidity. Although rapid urease test positive rate for Helicobacter pylori was higher in group of non-NSAID related peptic ulcer disease, it seemed underestimate because of the test number of patients was low. The average total direct medical cost of inpatients with NSAID related peptic ulcer was NT$ 36,491 and non-NSAID related peptic ulcer was NT$ 37,266.1. There were no significant difference in medical costs of standard care , intensive care , blood products,endoscopy, endoscopic hemostasis, surgery, CT scan , ultrasound, laboratory tests,medications, doctor¡¦s service between the two groups. Diagnostic and therapeutic procedures were no statistically significant difference, including blood transfusion,CT scan, endoscopic hemostasis, surgery, symptoms presentations, and intensive care. In this study, the duration for using NSAID was within 30 days for inpatients associated with NSAID related peptic ulcer, which had a substantial excess numbers of ulcer hospitalization. Since the common disease for using NSAID is osteoarthritis,which is very popular in elderly, therefore, we suggested that the policy makers of the National Health Insurance should be aware that preventive usage of proton pump inhibitors for the elder population who need frequent use of NSAIDs might decrease NSAID related ulcer complications.

Physical and psychological characteristics in adolescence and risk of gastrointestinal disease in adulthood

Melinder, Carren Anyango January 2017 (has links)
Background and objectives: Physical fitness and stress resilience may influence the risk of gastrointestinal (GI) disease. High physical fitness level may reduce levels of systemic inflammation while psychosocial stress exposure can increase inflammation levels and intestinal permeability. The main objectives are to evaluate if poorer physical fitness and stress resilience in adolescence are associated with a raised risk of inflammatory bowel disease (IBD), peptic ulcer disease (PUD) and GI infections in adulthood and to assess evidence of causality. Materials and methods: Swedish registers provided information on a cohort of approximately 250,000 men who underwent military conscription assessments in late adolescence (1969 –1976) with follow-up until December 2009 (up to age 57 years). Cox regression evaluated the associations of physical fitness and stress resilience in adolescence with subsequent GI disease risk in adulthood. Results and conclusions: IBD: Poor physical fitness was associated with an increased risk of IBD. The association may be explained (in part) by prodromal disease activity reducing exercise capacity and therefore fitness. Low stress resilience was associated with an increased risk of receiving an IBD diagnosis. Stress may not be an important cause of IBD but may increase the likelihood of conversion from subclinical to symptomatic disease. PUD: Low stress resilience was associated with an increased risk of PUD. This may be explained by a combination of physiological and behavioural mechanisms that increase susceptibility to H. pylori infections and other risk factors. GI infections: Low stress resilience was associated with a reduced risk of GI infections, including enteric infections rather than the hypothesised increased risk.

Iron Ulcers, an Uncommon Phenomena

Wike, Samuel Hunter, Pham, Thi Le Na, Sadiq, Madeeha Syed, Cecchini, Arthur Anthony, Reece, Blair Rose 25 April 2023 (has links)
Oral iron replacement therapy is often used as a first-line modality for the treatment of iron deficiency anemia (IDA). Oral iron replacement options include tablets, capsules, and liquid formulations. Esophagitis due to iron tablet administration is a well-documented phenomenon, yet peptic ulcer disease secondary to iron tablet administration is less well-known. An 83-year-old female with a past medical history of chronic kidney disease stage V, anemia of inflammatory disease, heart failure with preserved ejection fraction, and gastroesophageal reflux disease presented to the hospital with diffuse abdominal pain and dark red emesis. She was started on ferrous sulfate supplementation two weeks ago and described progressive abdominal pain and nausea since beginning the medication. She was not taking nonsteroidal anti-inflammatories (NSAIDs), antiplatelets, or anticoagulants. Six months ago, she had an unremarkable upper endoscopy performed for new-onset gastroesophageal reflux disease. Laboratory studies revealed a hemoglobin of 7.3 mg/dL and due to a concern for rapid blood loss, she was given one unit of packed red blood cells. A non-contrast computed tomography was performed showing wall thickening of the stomach and the first two portions of the duodenum. A possible ulcer was seen in the distal posterior stomach. The patient was made NPO, and twice daily intravenous pantoprazole was started. An upper endoscopy was performed which revealed a 2.5 cm clean-based ulcer in the duodenal bulb. Biopsies showed acute inflammation and positivity for iron debris but were negative for Helicobacter pylori. Once daily pantoprazole was continued, and her ferrous sulfate tablets were discontinued. Her symptoms did not return. Ferrous sulfate may erode and ulcerate the gastric and duodenal mucosa like that of a chemical burn. Iron deposits may be seen on biopsies performed with Prussian blue staining. Brown crystalline deposits may be seen on hematoxylin and eosin staining. Iron injury may be seen in pill or capsule formulations due to a concentration effect, but this is typically not seen with solution forms. Treatment includes discontinuation of tablet or capsule formulations and substitution with liquid forms.

Functional Dyspepsia : Symptoms and Response to Omeprazole in the Short Term

Bolling-Sternevald, Elisabeth January 2003 (has links)
Gastrointestinal symptoms have a prevalence of 20-40% in the general adult population in the Western world. These symptoms are generally considered to be poor predictors of organic findings [e.g. peptic ulcer disease (PUD) or malignancy]. Approximately 50% of patients seeking care for such symptoms have no organic explanation for these upon investigation. When other organic or other functional conditions are excluded [e.g. PUD, gastroesophageal reflux disease (GERD), irritable bowel syndrome (IBS)] the remaining patients are labelled as having functional dyspepsia (persistent or recurrent pain and/or discomfort centred in the upper abdomen). Management of functional dyspepsia remains a challenge, reflecting the heterogeneity of the patients and the uncertain role of drug treatment. Also, prognostic factors for treatment success are largely unknown. I have therefore performed a series of studies to shed light on these issues: The first study (Paper I) was performed in a randomly selected adult population (n=1,001) assessing upper and lower gastrointestinal symptoms at two occasions with 1 to 6 month intervals. The results show that gastrointestinal symptoms are common (57%) and fluctuate to some extent in the shorter term. Troublesome dyspeptic symptoms remain in two out of three individuals. This proportion was similar whether or not organic findings were present. In the second study (Paper II) 799 patients with dyspeptic symptoms were evaluated with regard to whether gastrointestinal symptoms, identified by self-administered questionnaires, correlate with endoscopic diagnoses and discriminate organic from non-organic (functional) dyspepsia. The impact of dyspeptic symptoms on health-related well-being was also evaluated. Approximately 50% of these dyspeptic patients were found to have functional dyspepsia at upper endoscopy. A difference was discovered in the symptom profile between patients with organic and functional dyspepsia. Predicting factors for functional dyspepsia were found. This study shows that use of self-administered symptom questionnaires may aid in clinical decision making for patient management, e.g. by reducing the number of endoscopies, although probabilities of risks for organic dyspepsia are difficult to transfer to management of the individual patient. The results also indicate that the health-related well-being in patients with functional and organic dyspepsia is impaired to the same extent, illustrating the need for effective treatment of patients with functional dyspepsia, a group not well served by currently available treatment modalities. The aim of the third study (Paper III) was to develop and evaluate a selfadministered questionnaire focusing on upper abdominal and reflux complaints to allow for identification of patients with heartburn and factors that might predict symptom relief with omeprazole both in GERD and functional dyspepsia patients. The diagnostic validity of the questionnaire was tested against endoscopy and 24-hour pH monitoring. The questionnaire had a sensitivity of 92%, but a low specificity of 19%. Symptom relief by omeprazole was best predicted by the presence of predominant heartburn described as ‘a burning feeling rising from the stomach or lower chest up towards the neck’ and ‘relief from antacids’. These results indicate that this questionnaire which used descriptive language, appeared to be useful in identifying heartburn and predicting responses to omeprazole in patients with upper gastrointestinal symptoms. The fourth study (Paper IV) was a pilot study investigating the symptom response to omeprazole 20 mg twice daily or placebo for a duration of 14 days in 197 patients with functional dyspepsia. We concluded that a subset of patients with functional dyspepsia, with or without heartburn, would respond to therapy with omeprazole. In the final study (Paper V) the aim was to identify prognostic factors for the treatment success to a 4-week course of omeprazole 10 or 20 mg once daily in 826 patients with functional dyspepsia. The most highly discriminating predictor of treatment success was the number of days without dyspeptic symptoms during the first week of treatment. Fewer days with symptoms during the first week indicated higher response rates at four weeks. In addition, positive predictors of treatment response to omeprazole were identified as age >40 years, bothersome heartburn, low scores of bloating and diarrhoea, history of symptoms for <3 months and low impairment of vitality at baseline. The results indicate that early response during the first week to treatment with a proton pump inhibitor seems to predict treatment success after four weeks in patients with functional dyspepsia. Conclusion: These studies have shown that a large proportion of adult individuals in society, both those who seek and those who do not seek medical care, suffer from symptoms located in the upper part of the abdomen regardless of whether an organic cause is present. A subset of patients without organic findings and other functional conditions, i.e. functional dyspepsia, respond to therapy with omeprazole irrespective of the presence or absence of heartburn . An excellent way to predict the response to a full course of omeprazole in functional dyspepsia is to assess the early response (first week) to treatment. These findings allow for better and faster targeting of acid inhibitory therapy in functional dyspepsia, which potentially can result in more effective clinical management of these patients and savings of health care resources.
