ABSTRACT
Based on UHPLC-Q-Exactive Orbitrap HRMS coupled with the network pharmacology and molecular docking, the common material basis and molecular mechanisms of Bletillae Rhizoma for melasma, gastrointestinal hemorrhage, lung cancer and bronchoplumonary inflammation as "homotherapy for heteropathy" were explored. The fingerprint of 17 batches of Bletillae Rhizoma from different areas was established using HPLC, and the similarity analysis was carried out. The common chemical components of the 17 batches of Bletillae Rhizoma were identified using UHPLC-Q-Exactive Orbitrap HRMS. Depending on the bioavailability and drug-like properties of the common components, the active chemical components were screened, and then their protein targets were collected using the Traditional Chinese Medicine Database and Analysis Platform(TCMSP) and SwissTargetPrediction database. The protein targets related to diseases were retrieved from the databases DrugBank, TTD and GeneCards to produce a Venn diagram. The shared targets were obtained between drugs and diseases as "homotherapy for heteropathy" targets. The protein-protein interaction(PPI) was analyzed with the STRING database, and KEGG and GO analyses of the "homotherapy for heteropathy" targets were performed using the Bioconductor database. Cytoscape 3.7.2 software was employed to construct the "chemical components of Bletillae Rhizoma-homotherapy for heteropathy targets" network and PPI network, and topological analysis was conducted to screen out the key active chemical components and core targets. Finally, the affinity between the active components and core targets was evaluated using the molecular docking by AutoDock Vina 4.2.6, which verified the interaction between them. Thirteen common peaks were identified by fingerprint chromatography, and the similarity between different batches was 0.941-0.998. Fifty-three chemical components were identified by mass spectrometry in Bletillae Rhizoma, and 18 common chemical constituents were obtained in the 17 batches of Bletillae Rhizoma. Network pharmacologic screening showed that the pharmacodynamic substances of Bletillae Rhizoma for melasma, gastrointestinal hemo-rrhage, lung cancer and bronchoplumonary inflammation with "homotherapy for heteropathy" were 11 compounds, such as polysaccharides, biphenanthrenes, dihydrophenanthrenes and bibenzyls. There were 42 common targets identified for the treatment of different diseases. These targets were involved in biological processes such as cell response to chemical stress, reactive oxygen species and positive regulation of protein kinase B signal transduction. They were also involved in 121 signaling pathways, encompassing vital pathways such as PI3K-Akt, ErbB, Rap1, FoxO, MAPK and estrogen. Molecular docking results showed a strong affinity between the key active components and the core targets. This study provides a preliminary explanation of how Bletillae Rhizoma exerts its therapeutic effect on chloasma, gastrointestinal hemorrhage, lung cancer, and bronchopneumonic lesions as "homotherapy for heteropathy" through a combined action involving multiple components, targets, and pathways. These findings offer a certain theoretical basis for the further deve-lopment and application of Bletillae Rhizoma.

PURPOSE: Acute gastrointestinal bleeding is a common emergency. Tranexamic acid (TXA) reduces clot breakdown by inhibiting the action of plasmin and has been shown to reduce the need for blood transfusion in trauma, surgical procedures, and upper gastrointestinal bleeding. This study examined the efficiency of intravenous TXA in patients with acute lower gastrointestinal bleeding. METHODS: Eighty-one patients aged >18 years with lower GI hemorrhage, presenting as active rectal bleeding and anemia (hemoglobin lower than 11 g/dL or a decrease of 2 gr/dl from the patient's base level), were enrolled in this single center, double blind prospective research. Patients were randomly assigned to receive intravenous TXA or placebo from admission until colonoscopy took place. The need for transfusion of packed red blood cells (PRBC) and number of units was recorded and compared between the two groups. RESULTS: Eighty-one patients were randomized in this study, thirty-nine in the TXA arm, and forty-two in the placebo arm. Patient characteristics did not differ between the groups. Forty-three out of the 81 patients received blood transfusion; twenty-two were on the placebo arm and twenty-one on the TXA arm (p = 0.89). Twenty-nine patients required 2 or more units, 14 in the TXA arm and 15 in the placebo arm (p = 0.98). CONCLUSIONS: Intravenous TXA has no significant effect on blood requirement in patients with lower GI bleeding. There was no difference in the consumption of PRBC units among the patients in the placebo and TXA groups. It seems that tranexamic acid has no significant effect on transfusion of PRBC units in lower GI bleeding.

Introduction: Rectal bleeding commonly occurs in elderly patients using blood thinners, posing management challenges due to limited guidance on reversal agents and medication restart criteria. This study aims to review the demographics and management of elderly patients with rectal bleeding while on blood thinners. Methods: A retrospective analysis of patients aged 60 or older presenting with rectal bleeding at West Suffolk Hospital's emergency department was conducted from January 2018 to December 2020. Data were extracted from electronic records, focusing on patients using blood thinners and adhering to British Society of Gastroenterology guidelines. All patients ceased blood-thinning medications upon admission. The hospital's ethics committee approved the study, which focused on demographics, diagnosis, and management, particularly regarding re-initiation of blood-thinning medicines. Results: During the study period, 170 patients were admitted to the emergency department of West Suffolk Hospital. 93 (54.71%) patients were included in the study. The average age of the participants was 82 years, and 62.3% were male. All patients were followed up for three months. Atrial fibrillation accounted for 52% of patients, while previous strokes accounted for 20%. The most typical pathology was diverticulosis.Regarding restarting of anticoagulants, Among patients on DOAC (Direct oral anticoagulant), 39% were restarted on discharge, 23% were switched to warfarin, and another 23% were not restarted; 15% planned to restart after seven days. For those on Warfarin, 62% were restarted on discharge, 22% stopped the medication, and the rest were switched to Dual Oral Anticoagulant. Among aspirin patients, 60% were restarted at discharge, while the remaining discontinued. All patients receiving clopidogrel and dual antiplatelet therapy were started at discharge. None of the patients were readmitted during the follow-up period of 3 months. Conclusion: Restarting of blood-thinning drugs in patients with rectal bleeding is subject to individual patient variation. Necessitates more extensive trials to achieve greater standardization.

BACKGROUND: Previous experimental and clinical studies suggested a beneficial effect of statins, metformin, angiotensin-converting-enzyme inhibitors and angiotensin II receptor blockers (RASi) on portal hypertension. Still, their effects on hard cirrhosis-related clinical endpoints, such as variceal bleeding and bleeding-related mortality, remain to be investigated. METHODS: Thus, we recorded the use of statins, metformin and RASi in a large cohort of cirrhotic patients undergoing endoscopic band ligation (EBL) for primary (PP, n = 440) and secondary bleeding prophylaxis (SP, n = 480) between 01/2000 and 05/2020. Variceal (re-) bleeding and survival rates were compared between patients with vs. without these co-medications. RESULTS: A total of 920 cirrhotic patients with varices were included. At first EBL, median MELD was 13 and 515 (56%) patients showed ascites. Statins, metformin and RASi were used by 49 (5.3%), 74 (8%), and 91 (9.9%) patients, respectively. MELD and platelet counts were similar in patients with and without the co-medications of interest. Rates of first variceal bleeding and variceal rebleeding at 2 years were 5.2% and 11.7%, respectively. Neither of the co-medications were associated with decreased first bleeding rates (log-rank tests in PP: statins p = 0.813, metformin p = 0.862, RASi p = 0.919) nor rebleeding rates (log-rank tests in SP: statin p = 0.113, metformin p = 0.348, RASi p = 0.273). Similar mortality rates were documented in patients with and without co-medications for PP (log-rank tests: statins p = 0.630, metformin p = 0.591, RASi p = 0.064) and for SP (statins p = 0.720, metformin p = 0.584, RASi p = 0.118). CONCLUSION: In clinical practice, variceal bleeding and mortality rates of cirrhotic patients were not reduced by co-medication with statins, metformin or RASi. Nevertheless, we recommend the use of these co-medications by indication, as they may still exert beneficial effects on non-bleeding complications in patients with liver cirrhosis.

BACKGROUND: Acute gastrointestinal bleeding (AGIB) is common in older patients but the use of iron in this context remains understudied. AIMS: This study aimed to evaluate prospectively the efficacy of ferric carboxymaltose to treat anaemia in older patients after AGIB. METHODS: This randomised double-blinded placebo-controlled clinical trial was conducted in 10 French centres. Eligible patients were 65 years or more, had controlled upper or lower gastrointestinal bleeding and a haemoglobin level of 9-11 g/dl. Patients were randomly assigned, in a 1:1 ratio, to receive either one intravenous iron injection of ferric carboxymaltose or one injection of saline solution. The primary endpoint was the difference in haemoglobin level between day 0 and day 42. Secondary endpoints were treatment-emergent adverse events, serious adverse events, rehospitalisation and improvement of quality of life (QOL) at day 180. RESULTS: From January 2013 to January 2017, 59 patients were included. The median age of patients was 81.9 [75.8, 87.3] years. At day 42, a significant difference in haemoglobin level increase was observed (2.49 g/dl in the ferric carboxymaltose group vs. 1.56 g/dl in the placebo group, P = 0.02). At day 180, QOL, measured on European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30, improved by 10.5 points in the ferric carboxymaltose group and by 8.2 points in the placebo group (P = 0.56). Rates of adverse events and rehospitalisation were similar in the two groups. CONCLUSIONS: Intravenous iron seems safe and effective to treat anaemia in older patients after AGIB and should be considered as a standard-of-care treatment. ClinicalTrials.gov (NCT01690585).

BACKGROUND: Radiation proctitis (RP) is a significant complication of pelvic radiation. Effective treatments for chronic RP are currently lacking. We report a case where chronic RP was successfully managed by metformin and butyrate (M-B) enema and suppository therapy. CASE PRESENTATION: A 70-year-old Asian male was diagnosed with prostate cancer of bilateral lobes, underwent definitive radiotherapy to the prostate of 76 Gy in 38 fractions and six months of androgen deprivation therapy. Despite a stable PSA nadir of 0.2 ng/mL for 10 months post-radiotherapy, he developed intermittent rectal bleeding, and was diagnosed as chronic RP. Symptoms persisted despite two months of oral mesalamine, mesalamine enema and hydrocortisone enema treatment. Transition to daily 2% metformin and butyrate (M-B) enema for one week led to significant improvement, followed by maintenance therapy with daily 2.0% M-B suppository for three weeks, resulting in continued reduction of rectal bleeding. Endoscopic examination and biopsy demonstrated a good therapeutic effect. CONCLUSIONS: M-B enema and suppository may be an effective treatment for chronic RP.

BACKGROUND: Thalidomide has been used for angioectasia-associated refractory gastrointestinal bleeding (GIB), with studies showing variable efficacy and side effects profile. We conducted a meta-analysis to reconcile the data. METHODS: Online databases were searched for studies evaluating thalidomide in patients with refractory/recurrent GIB due to angioectasias. The outcomes of interest were cessation of bleeding, rebleeding, need for blood transfusion, hospitalization and adverse events. Pooled proportions for incidence, and odds ratios (OR) for comparison with control were calculated along with 95% confidence interval (CI). RESULTS: A total of seven studies with 346 patients (n = 269 thalidomide, n = 77 control) were included. Thalidomide dose was usually started at 50-100mg/day. The mean age was 65 years, 45% patients were men, and mean follow-up was 1.8 years. The pooled clinical outcomes with thalidomide were: cessation of bleeding 42.2% (95% CI 36.02 to 48.41), rebleeding 30%, need for blood transfusion 20.1%, hospitalization 40% and adverse events 55.9%. When compared with the control group in 2 studies, patients on thalidomide had significantly higher odds of cessation of bleeding (OR 21.40, 95% CI 5.78 to 79.29, p < 0.00001) and adverse events, with lower need for blood transfusion and hospitalization. DISCUSSION: In patients with angioectasias-related refractory/recurrent GIB, the use of thalidomide results in significantly decreased bleeding risk and may play a role in the management of such patients.

BACKGROUND AND AIMS: Patients with Child-Turcotte-Pugh class B and C cirrhosis with upper gastrointestinal bleeding (UGIB) have systemic as well as localized (in the mucosa of the esophagus and stomach) fibrinolysis. The aim of this study was to evaluate the efficacy and safety of tranexamic acid in the treatment of acute UGIB in patients with cirrhosis. APPROACH AND RESULTS: A total of 600 patients with advanced liver cirrhosis (Child-Turcotte-Pugh class B or C) presenting with UGIB were randomly allocated to either the tranexamic acid (n=300) or the placebo group (n=300). The primary outcome measure was the proportion of patients developing 5-day treatment failure. Failure to control bleeding by day 5 was seen in 19/300 (6.3%) patients in the tranexamic acid group and 40/300 (13.3%) patients in the placebo group ( p =0.006). Esophageal endoscopic variceal ligation (EVL) site as a source of failure to control bleeding by day 5 among patients undergoing first-time esophageal EVL (excluding patients with a previous post-EVL ulcer as a source of bleed) was seen in 11/222 (4.9%) patients in the tranexamic acid group and 27/225 (1212.0%) patients in the placebo group ( p =0.005). However, 5-day and 6-week mortality was similar in the tranexamic acid and placebo groups. CONCLUSIONS: Tranexamic acid significantly reduces the failure to control bleeding by day 5 and failure to prevent rebleeding after day 5 to 6 weeks in patients with advanced liver cirrhosis (Child-Turcotte-Pugh class B or C) presenting with UGIB, by preventing bleeding from the EVL site.

BACKGROUND: Amiodarone is an established treatment for atrial fibrillation (AF) but might interfere with the metabolism of apixaban or warfarin. Therefore, the aim was to investigate the occurrence of major bleeding among patients with AF treated with amiodarone in combination with apixaban or warfarin. METHODS: Retrospective observational study using Swedish health registers. All patients with AF in the National Patient Register and the National Dispensed Drug Register with concomitant use of amiodarone and warfarin or apixaban between 1 June 2013 and 31 December 2018 were included. Propensity score matching was performed, and matched cohorts were compared using Cox proportional HRs. The primary outcome was major bleeding resulting in hospitalisation based on International Classification of Diseases (ICD)-10 codes. Secondary outcomes included intracranial bleeding, gastrointestinal bleeding and other bleeding. Exploratory outcomes included ischaemic stroke/systemic embolism and all-cause/cardiovascular (CV) mortality. RESULTS: A total of 12 103 patients met the inclusion criteria and 8686 patients were included after propensity score matching. Rates of major bleeding were similar in the apixaban (4.3/100 patient-years) and warfarin cohort (4.5/100 patient-years) (HR: 1.03; 95% CI: 0.76 to 1.39) during median follow-up of 4.4 months. Similar findings were observed for secondary outcomes including gastrointestinal bleeding and other bleeding, and exploratory outcomes including ischaemic stroke/systemic embolism and all-cause/CV mortality. CONCLUSIONS: Among patients treated with amiodarone in combination with apixaban or warfarin, major bleeding and thromboembolic events were rare and with no significant difference between the treatment groups.

Variceal bleeding is a major complication and the leading cause of death in patients with cirrhosis and portal hypertension. This study aims to compare the efficacy and safety of terlipressin vs octreotide as an adjuvant to endoscopic management of patients with esophageal variceal bleeding in a real-time scenario. We reviewed the medical records of patients with esophageal variceal bleeding from January 2005 to December 2020 at our tertiary care Aga Khan University Hospital. Mortality was assessed after 6 weeks. A total of 842 patients with variceal bleed were evaluated. 624 patients (74.1%) and 218 patients (25.9%) received Terlipressin and Octreotide respectively. On multiple regression analysis, cardiac events during hospital stay (OR: 11.22), presence of Porto-systemic encephalopathy (OR: 3.79), and elevated bilirubin levels at the time of presentation were found to be independent risk factors for increased six weeks mortality. Moreover, cardiac events during hospital stay (OR: 3.26), Porto-systemic encephalopathy at presentation (OR: 3.06), and octreotide administration (OR: 1.80) were identified as independent risk factors for increased length of hospital stay. Terlipressin and Octreotide have similar outcomes in terms of control of bleeding, hospital stay, mortality, and side effects when used as adjuvant therapy for the management of variceal bleeding.

BACKGROUND: Osteoarthritis (OA) is a major cause of chronic pain. Non-steroidal anti-inflammatory drugs (NSAIDs) are analgesics commonly used for musculoskeletal pain; however, NSAIDs can increase the risk of certain adverse events, such as gastrointestinal bleeding, edema, heart failure, and hypertension. OBJECTIVE: The objective of this study was to characterize existing comorbidities among patients with OA. For patients with OA with and without a coexisting medical condition of interest (CMCOI), we estimated the prevalence of prescribing and dispensing NSAIDs pre-OA and post-OA diagnosis. METHODS: Data from three large administrative claims databases were used to construct an OA retrospective cohort. Databases leveraged were IBM MarketScan Medicare Supplemental Database (MDCR), IBM MarketScan Commercial Database (CCAE), and Optum's de-identified Clinformatics® Data Mart Database (Optum CDM). The OA study population was defined to be those patients who had an OA diagnosis from an inpatient or outpatient visit with at least 365 days of prior observation time in the database during January 2000 through May 2021. Asthma, cardiovascular disorders, renal impairment, and gastrointestinal bleeding risks were the CMCOI of interest. Patients with OA were then classified as having or not having evidence of a CMCOI. For both groups, NSAID dispensing patterns pre-OA and post-OA diagnosis were identified. Descriptive analysis was performed within the Observational Health Data Sciences and Informatics framework. RESULTS: In each database, the proportion of the OA population with at least one CMCOI was nearly 50% or more (48.0% CCAE; 74.4% MDCR; 68.6% Optum CDM). Cardiovascular disease was the most commonly observed CMCOI in each database, and in two databases, nearly one in four patients with OA had two or more CMCOI (23.2% MDCR; 22.6% Optum CDM). Among the OA population with CMCOI, NSAID utilization post-OA diagnosis ranged from 33.0 to 46.2%. Following diagnosis of OA, an increase in the prescribing and dispensing of NSAIDs was observed in all databases, regardless of patient CMCOI presence. CONCLUSIONS: This study provides real-world evidence of the pattern of prescribing and dispensing of NSAIDs among patients with OA with and without CMCOI, which indicates that at least half of patients with OA in the USA have a coexisting condition. These conditions may increase the risk of side effects commonly associated with NSAIDs. Yet, at least 32% of these patients were prescribed and dispensed NSAIDs. These data support the importance of shared decision making between healthcare professionals and patients when considering NSAIDs for the treatment of OA in patients with NSAID-relevant coexisting medical conditions.

BACKGROUND: Proton pump inhibitors (PPI) are frequently used in patients with cirrhosis. AIMS: This study aimed to determine whether PPI use is associated with the prognosis of cirrhotic patients. METHODS: We conducted a multicentre retrospective cohort study involving 1485 patients who had experienced hepatic encephalopathy (HE) from 7 referral centres in Korea. The primary outcome was overall survival and secondary outcomes included the development of cirrhotic complications, including recurrent HE, spontaneous bacterial peritonitis (SBP), hepatorenal syndrome (HRS), and gastrointestinal bleeding. Patients treated with PPI with a mean defined daily dose (mDDD) ≥0.5 (high-dose PPI group) were compared to those treated with PPI of an mDDD < 0.5 (No or low-dose PPI group) for each outcome. RESULTS: Among 1485 patients (median age, 61 years; male, 61%), 232 were assigned to the high-dose PPI group. High-dose PPI use was independently associated with a higher risk of death (adjusted HR [aHR] = 1.71, 95% confidence interval [CI] = 1.38-2.11, p < 0.001). This result was reproducible after propensity score-matching (PSM) (aHR = 1.90, 95% CI = 1.49-2.44, p < 0.001). High-dose PPI use was an independent risk factor of recurrent HE (before PSM: aHR = 2.04, 95% CI = 1.66-2.51, p < 0.001; after PSM: aHR = 2.16, 95% CI = 1.70-2.74, p < 0.001), SBP (before PSM: aHR = 1.87, 95% CI = 1.43-2.43, p < 0.001; after PSM: aHR = 1.76, 95% CI = 1.31-2.36, p = 0.002), HRS (before PSM: aHR = 1.48, 95% CI = 1.02-2.15, p = 0.04; after PSM: aHR = 1.47, 95% CI = 0.95-2.28, p = 0.09), and gastrointestinal bleeding (before PSM: aHR = 1.46, 95% CI = 1.12-1.90, p = 0.006; after PSM: aHR = 1.74, 95% CI = 1.28-2.37, p < 0.001). CONCLUSIONS: The use of high-dose PPI was independently associated with increased risks of mortality and cirrhotic complications.
