The diagnosis primarily relies on bone marrow biopsy findings and the detection of the JAK2 V617F mutation, after the exclusion of secondary thrombocytosis due to conditions such as inflammation, hemolysis, infection, and iron deficiency. On the other hand, Ulcerative colitis represents an inflammatory disorder of the colon. The diagnosis of ulcerative colitis is established through clinical assessment, endoscopic examination, and histological criteria, without a discernible alternative etiology. The concomitant occurrence of these two conditions is infrequent. We present the case of an 85-year-old patient with a history of essential thrombocythemia who exhibited gastrointestinal symptoms characterized by alternating episodes of diarrhea and constipation. A subsequent colonoscopy accompanied by a biopsy revealed histological features consistent with ulcerative colitis. The patient was administered cytoreductive therapy in combination with mesalazine, resulting in favorable outcomes. Current literature addressing this association is limited, indicating the need for further investigative studies to elucidate the causal relationships between these two pathologies and to achieve improved therapeutic management strategies.展开更多

文摘BACKGROUND Diabetic foot ulcers(DFUs)present a significant clinical challenge due to their high prevalence and profound impact on morbidity.Ultrasound-assisted wound debridement(UAWD)has emerged as a potential therapeutic modality to improve healing outcomes in DFU management.AIM To evaluate the efficacy of UAWD in treating DFUs on wound closure rates,treatment duration,and quality of life outcomes.METHODS This systematic review and meta-analysis followed PRISMA guidelines,systematically searching PubMed,Embase,Web of Science,and the Cochrane Library with no date restrictions.Randomized controlled trials(RCTs)that evaluated the efficacy of UAWD in DFU treatment were included.Data were independently extracted by two reviewers,with discrepancies resolved through consensus or third-party consultation.The risk of bias was assessed using the Cochrane tool.χ2 and I2 statistics assessed heterogeneity,informing the use of fixed or random-effects models for meta-analysis,supplemented by sensitivity analysis and publication bias assessment through funnel plots and Egger's test.RESULTS From 1255 articles,seven RCTs met the inclusion criteria.The studies demonstrated that UAWD significantly reduced DFU healing time(standardized mean difference=-0.78,95%CI:-0.97 to-0.60,P<0.001)and increased healing rates(odds ratio=9.96,95%CI:5.99 to 16.56,P<0.001)compared to standard care.Sensitivity analysis confirmed the stability of these results,and no significant publication bias was detected.CONCLUSION UAWD is a promising adjunctive treatment for DFUs,significantly reducing healing times and increasing healing rates.These findings advocate for the integration of UAWD into standard DFU care protocols.
文摘Ulcerative colitis has baffled researchers since the early 20th century.The pre-vailing explanation attributes the chronic recurring episodes of bloody diarrhea and abdominal pain to some form of immune abnormality,despite the lack of supporting evidence.This highlights the critical need for innovative research directions and methodologies to uncover the cause and develop a cure for this disease.By analyzing existing data from less than a dozen previously published studies,a novel,evidence-based pathogenesis was constructed,implicating colonic epithelial hydrogen peroxide as a causal factor in the development of this disease.This newly identified mechanism informed the creation of a ground-breaking class of therapeutics,known as reducing agents,which have demon-strated remarkable success in resolving colonic inflammation and restoring colonic health in patients with refractory ulcerative colitis.This paper outlines the timeline of these publications and reinterprets the findings within the context of contemporary biomedical science.
文摘BACKGROUND Ulcerative colitis(UC)is a chronic inflammatory disease affecting the colon.The most common psychological issue in UC patients is varying degrees of depre-ssion,which affects the condition and quality of life of UC patients and may lead to deterioration of the patient’s condition.UC drugs combined with anti-anxiety and antidepression drugs can alleviate symptoms of both depression and UC.Brain-derived neurotrophic factor(BDNF)precursor(proBDNF)/p75 neurotrophin receptor(p75NTR)/sortilin and BDNF/tropomyosin receptor kinase B(TrkB)signalling balance is essential for maintaining brain homeostasis and preventing the development of depressive behaviours.AIM To explore the mechanism by which Wuling powder regulates the proBDNF/p75NTR/sortilin and BDNF/TrkB pathways in the treatment of UC with depre-ssion.METHODS Depression was established in C57BL/6J mice via chronic restraint stress,and the UC model was induced with dextran sodium sulfate(DSS).In the treatment stage,mesalazine(MS)was the basic treatment,Wuling powder was the experimental treatment,and fluoxetine was the positive control drug for treating depression.Changes in intestinal mucosal inflammation,behaviour,and the proBDNFp75NTR/sortilin and BDNF/TrkB pathways were evaluated.RESULTS In the depression groups,Wuling powder decreased the immobility time,increased the distance travelled in the central zone and the total distance travelled,and restored balance in the proBDNF/p75NTR/sortilin and BDNF/TrkB signalling pathways.In the DSS and chronic restraint stress+DSS groups,immobility time increased,distance travelled in the central zone and total distance travelled decreased,activity of the proBDNF/p75NTR/sortilin pathway was upregulated,and activity of the BDNF/TrkB pathway was downregulated,indicating that mice with UC often have comorbid depression.Compared with those of MS alone,Wuling powder combined with MS further decreased the colon histopathological scores and the expression levels of tumor necrosis factor-alpha and interleukin-6 mRNAs.CONCLUSION This study confirmed that Wuling powder may play an antidepressant role by regulating the balance of the proBDNF/p75NTR/sortilin and BDNF/TrkB signalling pathways and further relieve intestinal inflammation in UC.

文摘BACKGROUND Ulcerative colitis(UC)is a chronic inflammatory condition requiring continuous treatment and monitoring.There is limited pharmacokinetic data on vedolizumab during maintenance therapy and the effect of thiopurines on vedolizumab trough concentrations is unknown.AIM To investigate the exposure-response relationship of vedolizumab and the impact of thiopurine withdrawal in UC patients who have achieved sustained clinical and endoscopic remission during maintenance therapy.METHODS This is a post-hoc analysis of prospective randomized clinical trial(VIEWS)involving UC patients across 8 centers in Australia from 2018 to 2022.Patients in clinical and endoscopic remission were randomized to continue or withdraw thiopurine while receiving vedolizumab.We evaluated vedolizumab serum trough concentrations,presence of anti-vedolizumab antibodies,and clinical outcomes over 48 weeks to assess exposure-response asso-ciation and impact of thiopurine withdrawal.RESULTS There were 62 UC participants with mean age of 43.4 years and 42%were females.All participants received vedolizumab as maintenance therapy with 67.7%withdrew thiopurine.Vedolizumab serum trough concentrations remained stable over 48 weeks regardless of thiopurine use,with no anti-vedolizumab antibodies detected.Pa-tients with clinical remission had higher trough concentrations at week 48.In quartile analysis,a threshold of>11.3μg/mL was associated with sustained clinical remission,showing a sensitivity of 82.4%,specificity of 60.0%,and an area of receiver operating characteristic of 0.71(95%CI:0.49-0.93).Patients discontinuing thiopurine required higher vedolizumab concentrations for achieving remission.CONCLUSION A positive exposure-response relationship between vedolizumab trough concentrations and UC outcomes suggests that monitoring drug levels may be beneficial.While thiopurine did not influence vedolizumab levels,its with-drawal may necessitate higher vedolizumab trough concentrations to maintain remission.

文摘Diabetic foot ulcers(DFUs)represents a significant public health issue,with a rising global prevalence and severe potential complications including amputation.Traditional treatments often fall short due to various limitations such as high recurrence rates and extensive resource utilization.This editorial explores the innovative use of acellular fish skin grafts as a transformative approach in DFU management.Recent studies and a detailed case report highlight the efficacy of acellular fish skin grafts in accelerating wound closure,reducing dressing changes,and enhancing patient outcomes with a lower socio-economic burden.Despite their promise,challenges such as limited availability,patient acceptance,and the need for further research persist.Addressing these through more extensive randomized controlled trials and fostering a multidisciplinary treatment approach may optimize DFU care and reduce the global health burden associated with these complex wounds.
文摘BACKGROUND Bullous pemphigoid(BP)is an autoimmune blistering skin disorder.It is associated with other autoimmune disorders and the use of certain drugs.We describe a case of BP in a patient with ulcerative colitis(UC)treated with mesalamine.CASE SUMMARY A 38-year-old male patient with UC and a history of multiple flares was maintained on mesalamine with good clinical response.One year after starting mesalamine,he sought medical care following the onset of a severe itchy rash of several weeks’duration with a recent appearance of skin bullae.A biopsy of the skin revealed subepidermal blistering dermatitis with focal eosinophilic spongiosis.Direct immunofluorescence studies revealed linear IgG and C3 immune reactant deposits at the dermoepidermal junction,consistent with the diagnosis of BP.Prednisone therapy alleviated his symptoms.However,tapering prednisone led to re-eruption of the bullae.CONCLUSION BP should be considered when patients with UC develop skin manifestations.Although BP is not one of the extraintestinal manifestations of UC,there may be an association between these two conditions.Whether treatment with mesalamine or other therapeutic agents plays a role in the development of BP remains unclear.
文摘Objective Ulcerative colitis is a prevalent immunoinflammatory disease.Th17/Treg cell imbalance and gut microbiota dysregulation are key factors in ulcerative colitis pathogenesis.The actin cytoskeleton contributes to regulating the proliferation,differentiation,and migration of Th17 and Treg cells.Wdr63,a gene containing the WD repeat domain,participates in the structure and functional modulation of actin cytoskeleton.Recent research indicates that WDR63 may serve as a regulator of cell migration and metastasis via actin polymerization inhibition.This article aims to explore the effect of Wdr63 deletion on Th17/Treg cells and ulcerative colitis.Methods We constructed Wdr63-/-mice,induced colitis in mice using dextran sulfate sodium salt,collected colon tissue for histopathological staining,collected mesenteric lymph nodes for flow cytometry analysis,and collected healthy mouse feces for microbial diversity detection.Results Compared with wild-type colitis mice,Wdr63-/-colitis mice had a more pronounced shortening of colonic tissue,higher scores on disease activity index and histological damage index,Treg cells decreased and Th17 cells increased in colonic tissue and mesenteric lymph nodes,a lower level of anti-inflammatory cytokine IL-10,and a higher level of pro-inflammatory cytokine IL-17A.In addition,WDR63 has shown positive effects on maintaining intestinal microbiota homeostasis.It maintains the balance of Bacteroidota and Firmicutes,promoting the formation of beneficial intestinal bacteria linked to immune inflammation.Conclusion Wdr63 deletion aggravates ulcerative colitis in mice,WDR63 inhibits colonic inflammation likely by regulating Th17/Treg balance and maintains intestinal microbiota homeostasis.

文摘OBJECTIVE:To evaluate the therapeutic effects of Xiahuo Pingwei San(夏藿平胃散,XHPWS)on ulcerative colitis(UC)in mice and to explore the underlying mechanisms through a network pharmacology approach.METHODS:Ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF/MS)was utilized to identify the chemical composition and authenticate the active constituents of XHPWS,ensuring rigorous quality control across batches.A dextran sulfate sodium(DSS)-induced UC model was established in C57BL/6 mice,which were treated with XHPWS in vivo.The efficacy against UC was assessed by measuring parameters such as body weight,disease activity index(DAI)scores,and colon length.Levels of inflammatory cytokines,including interleukin-6(IL-6),interleukin-1β(IL-1β),and tumor necrosis factor-alpha(TNF-α),in colonic tissue were evaluated using enzymelinked immunosorbent assay(ELISA).Histological analysis of colon sections was conducted using hematoxylin and eosin staining.A network pharmacology approach was employed to explore the mechanisms of XHPWS and to predict its potential targets in UC treatment.Predicted protein expressions in colonic tissue were validated using immune-ohistochemistry(IHC)and Western blotting techniques.RESULTS:XHPWS effectively alle via ted DSS-induced UC symptoms in mice,as evidenced by restored body weight,reduced colon shortening,and decreased DAI scores.Histopathological examination revealed that XHPWS significantly reduced intestinal inflammatory infiltration,restored intestinal epithelial permeability,and increased goblet cell count.Network pharmacology analysis identified 63 active compounds in XHPWS and suggested that it might target 35 potential proteins associated with UC treatment.Functional enrichment analysis indicated that the protective mechanism of XHPWS could be related to the advanced glycation end products-receptor for advanced glycation end products(AGE-RAGE)signaling pathway.Notably,quercetin,kaempferol,wogonin,and nobiletin,the main components of XHPWS,showed strong correlations with the core targets.Additionally,experimental validation demonstrated that XHPWS significantly decreased levels of inflammatory cytokines interleukin 6(IL-6),interleukin 1 beta(IL-1β),and tumor necrosis factor alpha(TNF-α)in UC mice,while downregulating the expression of proteins related to the AGE-RAGE pathway.CONCLUSION:Our study demonstrated that XHPWS effectively alle via tes colitis symptoms and inflammation in UC mice,potentially through the regulation of the AGE-RAGE pathway.These findings provide strong evidence for the therapeutic potential of XHPWS in UC treatment,thereby broadening its clinical applications.
文摘Essential thrombocythemia is classified as a chronic myeloproliferative disorder characterized by the overproduction of platelets stemming from a megakaryocytic clone. The diagnosis primarily relies on bone marrow biopsy findings and the detection of the JAK2 V617F mutation, after the exclusion of secondary thrombocytosis due to conditions such as inflammation, hemolysis, infection, and iron deficiency. On the other hand, Ulcerative colitis represents an inflammatory disorder of the colon. The diagnosis of ulcerative colitis is established through clinical assessment, endoscopic examination, and histological criteria, without a discernible alternative etiology. The concomitant occurrence of these two conditions is infrequent. We present the case of an 85-year-old patient with a history of essential thrombocythemia who exhibited gastrointestinal symptoms characterized by alternating episodes of diarrhea and constipation. A subsequent colonoscopy accompanied by a biopsy revealed histological features consistent with ulcerative colitis. The patient was administered cytoreductive therapy in combination with mesalazine, resulting in favorable outcomes. Current literature addressing this association is limited, indicating the need for further investigative studies to elucidate the causal relationships between these two pathologies and to achieve improved therapeutic management strategies.
文摘Several issues should be considered before the surgical treatment of gastric ulcer perforations,including morbidity,mortality,and recurrence.However,an oftenoverlooked issue is determining the cause of the perforation.When the perforation is secondary to an underlying and undiagnosed malignancy,stomach resection inadequately treats the oncological disease and may increase postoperative morbidity and require re-surgery.
文摘BACKGROUND Peptic ulcer disease(PUD)during pregnancy is extremely rare.Perforated peptic ulcer(PPU)during pregnancy has high maternal and fetal mortality.Symptoms attributed to pregnancy and other diagnoses make the diagnosis of preoperative PPU during pregnancy and puerperium challenging.AIM To identify predictive factors for early diagnosis and treatment,and the association between the diagnosis and maternal/neonatal outcomes.METHODS We searched PubMed,PubMed Central,and Google Scholar.Articles were analyzed following preferred reporting items for systematic reviews and metaanalysis.The search items included:‘ulcer’,‘PUD’,‘pregnancy’,‘puerperium’,‘postpartum’,‘gravid’,‘labor’,‘perforated ulcer’,‘stomach ulcer’,‘duodenal ulcer’,‘peptic ulcer’.Additional studies were extracted by reviewing reference lists of retrieved studies.We included all available full-text cases and case series.Demographic,clinical,obstetric,diagnostic and treatment parameters,and outcomes were collected.RESULTS Forty-three cases were collected.The mean maternal age was 30.9 years;36.6%were multiparous,and 63.4%were nulliparous or primiparous,with multiparas being older than primiparas.Peptic ulcer perforated in 44.2%of postpartum and 55.8%of antepartum patients.Antepartum PPU incidence increased with advancing gestation 2.3%in the first,7%in the second,and 46.5%in the third trimester.The most common clinical findings were abdominal tenderness(72.1%),rigidity(34.9%),and distension(48.8%).Duodenal ulcer predominated(76.7%).In 79.5%,the time from delivery to surgery or vice versa was>24 hours.The maternal mortality during the third trimester and postpartum was 10%and 31.6%,respectively.The trimester of presentation did not influence maternal mortality.The fetal mortality was 34.8%,with all deaths in gestational weeks 24-32.CONCLUSION Almost all patients with PPU in pregnancy or puerperium presented during the third trimester or the first 8 days postpartum.Early intervention reduced fetal mortality but without influence on maternal mortality.Maternal mortality did not depend on the use of X-ray imaging,perforation location,delivery type,trimester of presentation,and maternal age.Explorative laparoscopy was never performed during pregnancy,only postpartum.
文摘BACKGROUND The use of proton pump inhibitors(PPIs)with the intent of reducing gastric acidity to the desired therapeutic level for treating bleeding peptic ulcer still has several limitations.AIM To compare intravenous PPIs and oral potassium competitive acid blockers(PCABs)administered prior to endoscopic treatment of bleeding peptic ulcers.METHODS This retrospective study involved 105 consecutive patients with non-variceal upper gastrointestinal bleeding(treated August 2023 to February 2024).Prior to emergency endoscopy,patients received either intravenous PPI(pantoprazole 80 mg bolus)or oral PCAB(tegoprazan 50 mg single-dose).Severity of bleeding was assessed using the Glasgow-Blatchford,Rockall,and AIMS65 scoring systems.Patients with severe comorbidities were excluded.Primary outcomes included need for therapeutic endoscopic intervention and occurrence of re-bleeding.Multivariate logistic regression was performed to adjust for potential confounding factors.RESULTS Total of the 105 patients,61 received intravenous PPI injection and 44 received oral PCAB prior to emergency endoscopy.To minimize selection bias,bleeding severity was assessed using the Glasgow-Blatchford,Rockall and AIMS65 scores,with no statistically significant differences observed between the two groups.During emergency endoscopy performed within 48 hours,ulcer bed status was classified according to the Forrest classification.The proportion of lesions graded IIa or higher was significantly lower in the PCAB group(P<0.001),as was the frequency of therapeutic endoscopy intervention(odds ratio=0.272,95%confidence interval:0.111-0.665,P=0.004).The frequency of re-bleeding events was statistically significantly higher in the PPI group(odds ratio=0.141,95%confidence interval:0.024-0.844,P=0.032).CONCLUSION Pre-endoscopic PCAB administration is more effective than PPI injection for upper gastrointestinal bleeding and may reduce ulcer bleeding mortality.
文摘BACKGROUND Gastric ulcer(GU),a common gastrointestinal condition,is influenced by multiple factors,particularly inflammatory and immune responses.Complete blood count(CBC)-derived inflammatory biomarkers represent a novel indicator of systemic inflammation and immune status;however,their association with GU remains unclear.AIM To investigate the association between CBC-derived inflammatory markers and GU.METHODS The study sample included individuals admitted to the Gastroenterology Unit of the Second Affiliated Hospital of Nanchang University from 2023 to 2024.We explored how each CBC-based inflammation indicator correlated with GU occurrence through logistic models,and assessed their predictive ability using receiver operating characteristic curve analysis.Additionally,we applied the least absolute shrinkage and selection operator method along with stepwise regression techniques to determine which inflammatory indicators were most significantly linked to GU.RESULTS Higher levels of log2 neutrophil-to-lymphocyte ratio,log2 monocyte-to-lymphocyte ratio,log2 systemic immuneinflammation index,log2 systemic inflammatory response index(SIRI),and log2 aggregate index of systemic inflammation were significantly associated with increased GU prevalence across all models,while log2 platelet-tolymphocyte ratio was significant only in the fully adjusted model.SIRI demonstrated the highest discriminative ability,with an area under the curve of 0.868.CONCLUSION Hematological indicators derived from CBC tests show a significant correlation with the prevalence of GU.Among them,SIRI demonstrated the most prominent association.These markers could act as practical tools in recognizing individuals more likely to develop GU.
文摘Ulcerative colitis(UC)is associated with an increased risk of developing colitisassociated colorectal cancer(caCRC),a major complication of long-standing disease.In this review,we examined the pathogenic association between UC and caCRC,highlighting the risk factors,molecular mechanisms,and current strategies for prevention and management.Compared to sporadic colorectal cancer,caCRC tends to occur at a younger age and is more frequently characterized by mucinous or signet-ring cell histology,proximal colonic involvement,and a higher incidence of synchronous lesions.The risk of caCRC increases 8-10 years after UC diagnosis and is influenced by disease duration,extent of colonic involvement,inflammatory burden,family history of colorectal cancer,and coexisting primary sclerosing cholangitis.The inflammation-to-cancer progression follows a multistep pathway of genetic alterations,advancing from low-grade to high-grade dysplasia,and ultimately to carcinoma.While chemopreventive agents such as 5-aminosalicylates may offer some benefit,surveillance colonoscopy remains the primary strategy for risk reduction.Early detection and individualized prevention strategies are critical for improving long-term outcomes in patients with UC.
文摘BACKGROUND Pain often predisposes patients with diabetic foot ulcers(DFUs)to negative emotional states,such as anxiety and depression,which can significantly impair treatment outcomes and recovery.However,very few studies have explored the relationship between anxiety,depression,and pain in DFUs,as well as the associated risk factors.AIM To analyze the correlation between anxiety,depression,and pain in patients with DFUs and to identify the associated risk factors.METHODS This study included 106 patients diagnosed with DFUs who were admitted to Tiantai County People’s Hospital between March 2022 and March 2024.The patients’anxiety levels were evaluated using Zung’s self-rating anxiety scale(SAS),depression status was assessed using Zung’s self-rating depression scale(SDS),and pain intensity was assessed using the visual analog scale(VAS).Subsequently,correlations between SAS,SDS,and VAS scores were analyzed.Univariate and multivariate analyses were conducted to explore the risk factors that contributed to anxiety and depression in patients with DFUs.RESULTS Among the 106 patients,39.62%exhibited anxiety and 43.40%presented with depression.Most patients experiencing anxiety or depression exhibited mild symptoms,with no severe cases observed.Compared with asymptomatic patients,those with anxiety or depression had significantly higher VAS scores.Correlation analysis indicated a significant positive relationship between both SAS and SDS scores and the VAS score.Univariate analysis identified sex,age,Wagner’s grade,presence of other complications,and smoking history as factors significantly associated with anxiety and depression.Multivariate analysis further confirmed that younger age,higher Wagner’s grade,and higher VAS scores were independent predictors of anxiety and depression.CONCLUSION This study reveals a significant positive correlation between anxiety,depression,and pain in patients with DFUs.This finding suggests that timely and effective pain intervention may be beneficial in alleviating negative emotions such as anxiety and depression.In addition,younger age(<50 years),higher Wagner’s grade,and higher VAS scores increase the risk of developing anxiety and depression in this patient population.
