Association of Cytokines with Clinical Indicators in Patients with Drug-Induced Liver Injury

Objective To explore characteristics of clinical parameters and cytokines in patients with drug-induced liver injury(DILI)caused by different drugs and their correlation with clinical indicators.Method The study was conducted on patients who were up to Review of Uncertainties in Confidence Assessment for Medical Tests(RUCAM)scoring criteria and clinically diagnosed with DILI.Based on Chinese herbal medicine,cardiovascular drugs,non-steroidal anti-inflammatory drugs(NSAIDs),antiinfective drugs,and other drugs,patients were divided into five groups.Cytokines were measured by Luminex technology.Baseline characteristics of clinical biochemical indicators and cytokines in DILI patients and their correlation were analyzed.Results 73 patients were enrolled.Age among five groups was statistically different(P=0.032).Alanine aminotransferase(ALT)(P=0.033)and aspartate aminotransferase(AST)(P=0.007)in NSAIDs group were higher than those in chinese herbal medicine group.Interleukin-6(IL-6)and tumor necrosis factor alpha(TNF-α)in patients with Chinese herbal medicine(IL-6:P<0.001;TNF-α:P<0.001)and cardiovascular medicine(IL-6:P=0.020;TNF-α:P=0.001)were lower than those in NSAIDs group.There was a positive correlation between ALT(r=0.697,P=0.025),AST(r=0.721,P=0.019),and IL-6 in NSAIDs group.Conclusion Older age may be more prone to DILI.Patients with NSAIDs have more severe liver damage in early stages of DILI,TNF-αand IL-6 may partake the inflammatory process of DILI.

Constipation and colonoscopy

Constipation is a significant sociomedical problem,which can be caused by various reasons.In the diagnostic approach to patients with constipation,the following data are usually sufficient:History,complete physical examination(including rectal examination),and additional diagnostic tests.A colonoscopy is not a necessary diagnostic method for all patients with constipation.However,if patients have alarm symptoms/signs,that suggest an organic reason for constipation,a colonoscopy is necessary.The most important alarm symptoms/signs are age>50 years,gastrointestinal bleeding,new-onset constipation,a palpable mass in the abdomen and rectum,weight loss,anemia,inflammatory bowel disease,and family history positive for colorectal cancer.Most endoscopists do not like to deal with patients with constipation.There are two reasons for this,namely the difficulty of endoscopy and the adequacy of preparation.Both are adversely affected by constipation.To improve the quality of colonoscopy in these patients,good examination techniques and often more extensive preparation are necessary.Good colonoscopy technique implies adequate psychological preparation of the patient,careful insertion of the endoscope with minimal insufflation,and early detection and resolution of loops.Bowel preparation for colonoscopy often requires prolonged preparation and sometimes the addition of other laxatives.

Relationship among Parkinson’s disease, constipation, microbes, and microbiological therapy

This comprehensive review elucidates the complex interplay between gut microbiota and constipation in Parkinson’s disease(PD),a prevalent non-motor symptom contributing significantly to patients’morbidity.A marked alteration in the gut microbiota,predominantly an increase in the abundance of Proteobacteria and Bacteroidetes,is observed in PD-related constipation.Conventional treatments,although safe,have failed to effectively alleviate symptoms,thereby necessitating the development of novel therapeutic strategies.Microbiological interventions such as prebiotics,probiotics,and fecal microbiota transplantation(FMT)hold therapeutic potential.While prebiotics improve bowel movements,probiotics are effective in enhancing stool consistency and alleviating abdominal discomfort.FMT shows potential for significantly alleviating constipation symptoms by restoring gut microbiota balance in patients with PD.Despite promising developments,the causal relationship between changes in gut microbiota and PD-related constipation remains elusive,highlighting the need for further research in this expanding field.

Preventive effect of kiwi berry(Actinidia arguta)on loperamide-induced constipation

Constipation is a common intestinal disease.Kiwi berries can effectively prevent constipation.However,studies have yet to be done to determine how kiwi berries prevent constipation.For two weeks,mice in this study were continually orally gavaged with kiwi berry,loperamide,or a combination of the 2.This study found that the kiwi group's feces had more water than the constipated mice.In addition,kiwi berries can speed up gastrointestinal transit(GI),shorten the time it takes to pass the first dark stool,and dramatically enhance body weight gain.In the interstitial cells of Caj al(ICC)cells and colon tissues,alterations in the protein expression of vasoactive intestinal peptide(VIP),cyclic adenosine monophosphate(cAMP),protein kinase A(PKA),and aquapcrin-3(AQP3)were found.At 3,6,and 12 h of ICC cells and mouse colon,the kiwi group's VIP,cAMP,PKA,and AQP3 protein expression levels were lower than those of the constipated mice.The kiwi berry can decrease the Firmicutes to Bacteroidetes ratio and boost the diversity and quantity of gut microbiota.By influencing the gut microbiota and VIP-cAMP-PKA-AQP3 signaling pathway,kiwi berries prevent constipation.

Hydrogen-rich water alleviates constipation by attenuating oxidative stress through the sirtuin1/nuclear factor-erythroid-2-related factor 2/heme oxygenase-1 signaling pathway

BACKGROUND Constipation,a highly prevalent functional gastrointestinal disorder,induces a significant burden on the quality of patients'life and is associated with substantial healthcare expenditures.Therefore,identifying efficient therapeutic modalities for constipation is of paramount importance.Oxidative stress is a pivotal contributor to colonic dysmotility and is the underlying pathology responsible for constipation symptoms.Consequently,we postulate that hydrogen therapy,an emerging and promising intervention,can serve as a safe and efficacious treatment for constipation.AIM To determine whether hydrogen-rich water(HRW)alleviates constipation and its potential mechanism.METHODS Constipation models were established by orally loperamide to Sprague-Dawley rats.Rats freely consumed HRW,and were recorded their 24 h total stool weight,fecal water content,and charcoal propulsion rate.Fecal samples were subjected to 16S rDNA gene sequencing.Serum non-targeted metabolomic analysis,malondialdehyde,and superoxide dismutase levels were determined.Colonic tissues were stained with hematoxylin and eosin,Alcian blue-periodic acid-Schiff,reactive oxygen species(ROS)immunofluorescence,and immunohistochemistry for cell growth factor receptor kit(c-kit),PGP 9.5,sirtuin1(SIRT1),nuclear factor-erythroid-2-related factor 2(Nrf2),and heme oxygenase-1(HO-1).Quantitative real-time PCR and western blot analysis were conducted to determine the expression level of SIRT1,Nrf2 and HO-1.A rescue experiment was conducted by intraperitoneally injecting the SIRT1 inhibitor,EX527,into constipated rats.NCM460 cells were induced with H2O2 and treated with the metabolites to evaluate ROS and SIRT1 expression.RESULTS HRW alleviated constipation symptoms by improving the total amount of stool over 24 h,fecal water content,charcoal propulsion rate,thickness of the intestinal mucus layer,c-kit expression,and the number of intestinal neurons.HRW modulated intestinal microbiota imbalance and abnormalities in serum metabolism.HRW could also reduce intestinal oxidative stress through the SIRT1/Nrf2/HO-1 signaling pathway.This regulatory effect on oxidative stress was confirmed via an intraperitoneal injection of a SIRT1 inhibitor to constipated rats.The serum metabolites,β-leucine(β-Leu)and traumatic acid,were also found to attenuate H2O2-induced oxidative stress in NCM460 cells by up-regulating SIRT1.CONCLUSION HRW attenuates constipation-associated intestinal oxidative stress via SIRT1/Nrf2/HO-1 signaling pathway,modulating gut microbiota and serum metabolites.β-Leu and traumatic acid are potential metabolites that upregulate SIRT1 expression and reduce oxidative stress.

Exploration of the complex origins of primary constipation

Constipation is a common gastrointestinal disorder characterized by infrequentbowel movements and difficulty in passing stools.It can significantly affect anindividual's quality of life and overall well-being.Understanding the causes ofconstipation is important for its effective management and treatment.In thispaper,we have reviewed the primary causes of constipation or functional constipation.Primary constipation is a bowel disorder associated with colonic oranorectal sensorimotor or neuromuscular dysfunction.As per the literature,it ismultifactorial and involves factors such as decreased interstitial cells of Cajal,altered colonic motility,enteric nervous system dysfunction,intestinal flora disturbances,and psychological influences.Clinical symptoms include difficulty indefecation,decreased frequency of defecation,or a feeling of incomplete evacuation.A comprehensive evaluation and management of constipation require aninterdisciplinary approach incorporating dietary modifications,lifestyle changes,pharmacotherapy,and psychological interventions.Further research is imperativeto explain the intricate mechanisms underlying constipation and develop targetedtherapies for improved patient outcomes.

Effects of Yigan Capsule on the expression of HMGB1,RAGE and NF-κB protein in rats with drug-induced liver injury

Objective:To study the effect of Yigan capsule on the expression of high mobility group protein B1(HMGB1),nuclear factor-B(NF-κB)and receptor for advanced glycation end products(RAGE)in anti-tuberculosis drug-induced liver injury(ATB-DILI),and to explore its protective effect and mechanism on ATB-DILI,so as to provide experimental basis for the clinical application of Yigan capsule.Methods:Twenty-four rats were divided into two groups.Except for the blank group(n=6),the other 18 rats were given isoniazid(INH)+rifampicin(RFP)(50 mg/kg.d)for 4 weeks.Then 18 rats were randomly divided into three groups(model group,low dose group of Yigan capsule and high dose group of Yigan capsule)according to 6 rats in each group.The blank group and the model group were given 0.9%sodium chloride solution by intragastric administration.The low dose group of Yigan capsule was 0.468 g/kg,and the high dose group of Yigan capsule was 1.872 g/kg[1].After 4 weeks,the pathological changes of liver were observed by HE staining.The contents of ALT,AST,ALP,γ-GT and TBIL were detected.The expression of HMGB1,NF-κBp65 and RAGE protein was detected by IHC.The expression levels of HMGB1,NF-κBp65,RAGE,TNF-αand IL-1βwere detected by WB.Result:HE staining showed that the structure of the liver in the model group was disordered,the liver cells showed swelling and fusion,the number of inflammatory cells increased and accompanied by punctate necrosis,while the above pathological changes in each treatment group of Yigan capsule were significantly improved.The contents of ALT,AST,ALP,γ-GT and TBIL in the model group were higher than those in the blank group(P<0.05).The contents of ALT,AST,ALP,γ-GT and TBIL in each treatment group were significantly lower than those in the model group(P<0.05).Compared with the blank group,the expression levels of TNF-αand IL-1βin the model group were increased(P<0.05),and the expression levels of HMGB1,NF-κBp65 and RAGE were increased(P<0.05).Compared with the model group,the expression levels of TNF-αand IL-1βin each treatment group of Yigan capsule decreased(P<0.05),and the expression of HMGB1,NF-κBp65 and RAGE decreased(P<0.05).Conclusion:Yigan capsule may inhibit the secretion of inflammatory factors through HMGB1/RAGE/NF-κBp65 signaling pathway,thus protecting ATB-DILI.

Microbiota treatment of functional constipation:Current status and future prospects

Functional constipation(FC)is a common disorder that is characterized by diffi-cult stool passage,infrequent bowel movement,or both.FC is highly prevalent,recurs often,accompanies severe diseases,and affects quality of life;therefore,safe and effective therapy with long-term benefits is urgently needed.Microbiota treatment has potential value for FC treatment.Microbiota treatments include modulators such as probiotics,prebiotics,synbiotics,postbiotics,and fecal micro-biota transplantation(FMT).Some probiotics and prebiotics have been adopted,and the efficacy of other microbiota modulators is being explored.FMT is con-sidered an emerging field because of its curative effects;nevertheless,substantial work must be performed before clinical implementation.

Preservation of superior rectal artery in laparoscopic colectomy:The best choice for slow transit constipation?

Laparoscopic colectomy with ileorectal anastomosis may be beneficial for patients with slow transit constipation who do not respond to conservative treatment,particularly if the superior rectal artery(SRA)is preserved.Several important concerns have been addressed in this commentary.It is important to first go over the definition of surgical procedure as it is used in this text.Second,the current study lacked a control group that had SRA preservation.Thirdly,it would be best to use a prospective,randomized controlled study.Lastly,a description of the mesenteric defect’s state following a laparoscopic colectomy is necessary.

Assessment of the triglyceride glucose index in adult patients with chronic diarrhea and constipation

BACKGROUND Accumulating evidence suggests that the gut microbiome is involved in the pathogenesis of insulin resistance(IR).However,the link between two of the most prevalent bowel disorders,chronic diarrhea and constipation,and the triglyceride glucose(TyG)index,a marker of IR,has not yet been investigated.AIM To investigate the potential association between TyG and the incidence of chronic diarrhea and constipation.METHODS This cross-sectional study enrolled 2400 participants from the National Health and Nutrition Examination Survey database from 2009-2010.TyG was used as an exposure variable,with chronic diarrhea and constipation as determined by the Bristol Stool Form Scale used as the outcome variables.A demographic investigation based on TyG quartile subgroups was performed.The application of multivariate logistic regression models and weighted generalized additive models revealed potential correlations between TyG,chronic diarrhea,and constipation.Subgroup analyses were performed to examine the stability of any potential associations.RESULTS In the chosen sample,chronic diarrhea had a prevalence of 8.00%,while chronic constipation had a prevalence of 8.04%.In multiple logistic regression,a more prominent positive association was found between TyG and chronic diarrhea,particularly in model 1(OR=1.45;95%CI:1.17-1.79,P=0.0007)and model 2(OR=1.40;95%CI:1.12-1.76,P=0.0033).No definite association was observed between the TyG levels and chronic constipation.The weighted generalized additive model findings suggested a more substantial positive association with chronic diarrhea when TyG was less than 9.63(OR=1.89;95%CI:1.05-3.41,P=0.0344),and another positive association with chronic constipation when it was greater than 8.2(OR=1.74;95%CI:1.02-2.95,P=0.0415).The results of the subgroup analyses further strengthen the extrapolation of these results to a wide range of populations.CONCLUSION Higher TyG levels were positively associated with abnormal bowel health.

Effect of KiwiBiotic on functional constipation and related symptoms:A prospective,single-center,randomized,comparative,crossover study

BACKGROUND Functional constipation(FC)is a common gastrointestinal disorder characterized by abdominal pain and bloating,which can greatly affect the quality of life of patients.Conventional treatments often yield suboptimal results,leading to the exploration of alternative therapeutic approaches.AIM To evaluate the efficacy of KiwiBiotic in the management of FC and related symptoms.METHODS This prospective,interventional,single-center,crossover study compared the safety and effectiveness of KiwiBiotic®vs psyllium husk in managing FC,abdominal pain,and bloating.Participants diagnosed with FC were randomly assigned to receive KiwiBiotic or psyllium husk during the two treatment periods,with a 14-day washout period between them.RESULTS Seventy participants were enrolled,32 of whom received KiwiBiotic followed by psyllium husk,and 33 received KiwiBiotic.KiwiBiotic showed superiority over psyllium husk in alleviating abdominal pain and bloating,as evidenced by significantly lower mean scores.Furthermore,KiwiBiotic resulted in more than 90.0%of patients experiencing relief from various constipation symptoms,while psyllium husk showed comparatively lower efficacy.CONCLUSION KiwiBiotic is an effective treatment option for FC,abdominal pain,and bloating,highlighting its potential as a promising alternative therapy for patients with FC and its associated symptoms.

Effectiveness of traditional chinese medicine nursing intervention on constipation and anxiety in chemotherapy

Background:In a study conducted from March to September 2021,124 cancer patients undergoing chemotherapy at our hospital were divided into two groups.The control group received routine inpatient nursing care,while the observation group received Traditional Chinese Medicine(TCM)nursing interventions in addition to routine care.Data analysis was conducted to compare the incidence of clinical adverse reactions,constipation scores,and changes in anxiety levels between the two groups.The results showed that the observation group,receiving TCM nursing interventions,had lower incidence of clinical adverse reactions and lower constipation scores compared to the control group.Additionally,anxiety levels were found to decrease significantly in the observation group post-intervention.These findings suggest that incorporating TCM nursing interventions in the care of cancer patients undergoing chemotherapy may help in reducing the occurrence of adverse reactions,alleviating constipation,and managing anxiety levels.Further research is needed to explore the full potential of integrating TCM into conventional nursing care for cancer patients.Methods:Following interventions,both groups experienced varying degrees of clinical adverse reactions,with the observation group demonstrating a significantly lower total incidence(29.03%)compared to the control group.This disparity was statistically significant(P<0.05).Furthermore,improvements were observed in defecation time(0.53±0.18)points and defecation frequency(1.17±0.25)points post-intervention.These findings suggest that the intervention had a positive impact on reducing adverse reactions and improving defecation patterns.Results:In a recent study,researchers found that individuals in the observation group experienced lower levels of difficulty with defecation and had a more regular defecation form compared to those in the control group.The results showed a significant difference in defecation difficulty and form,with the observation group scoring lower in both aspects.Interestingly,there was no significant difference in anxiety levels between the two groups prior to the intervention.However,after the intervention,both groups experienced a decrease in anxiety levels,with the observation group showing a greater reduction compared to the control group.This suggests that the intervention had a positive impact on reducing anxiety levels,particularly in the observation group,where anxiety scores were significantly lower.These findings highlight the possible benefits of certain interventions in improving both physical and psychological well-being.Conclusion:TCM nursing interventions have shown to be beneficial in reducing anxiety and improving constipation symptoms in cancer patients.These methods not only enhance the quality of life for patients but also offer a promising approach in clinical cancer treatment.The efficacy of TCM nursing highlights its value and encourages further promotion and application in future cancer care strategies.TCM nursing helps cancer patients undergoing chemotherapy with constipation and anxiety.

Functional constipation in children:What physicians should know

Functional constipation(FC)is considered the most common functional gastrointestinal disorder in children with a pooled global prevalence of 14.4%(95%confidence interval:11.2-17.6)when diagnosed based on the Rome IV criteria.Its pathophysiological mechanisms are thought be multifactorial and complicated,resulting in difficult management.Currently,the most effective medication,when used in parallel with toilet training,is osmotic laxatives.Children’s adherence to medication and parental concern regarding long-term laxative use are the main contributors to treatment failure.Recently,novel therapies with a high safety profile have been developed,such as probiotics,synbiotics,serotonin 5-hydroxytryptamine 4 receptor agonists,chloride channel activators,and herbal and transitional medicines;nonetheless,well-designed research to support the use of these therapies is needed.This review aims to focus on multiple aspects of FC in children,including global prevalence,pathogenesis,diagnostic criteria,tools,as well as conventional and novel treatment options,such as non-pharmacological management,including adequate fiber and fluid intake,physiotherapy,or neuromodulators.We also report that in very difficult cases,surgical intervention may be required.

Effects of probiotics and its fermented milk on constipation: a systematic review

This study reviewed clinical evidence of probiotics-mediated effects on constipation.Four databases were used in the literature searches,namely Cochrane Library,Embase,Pubmed,and Web of Science.The last retrieval time was March 2021.Collected data were analyzed by Review Manager(version 5.3)and Stata(version 14).The primary search retrieved 8418 articles after removing duplicates.Eventually,26 studies were included in the meta-analysis.Administration of probiotics signifi cantly increased stool frequency(MD:1.15 times/week;95%CI:0.59 to 1.70;P<0.0001),improved bloating(MD:-0.48;95%CI:-0.89 to-0.07;P=0.02),reduced abdominal pain(MD:-0.71;95%CI:-1.25 to-0.16;P=0.01),and improved quality of life(MD:-0.73;95%CI:-1.37 to-0.10;P=0.02).However,the clinical effect of intake of probiotics on stool consistency was non-signifi cant(MD:0.07;95%CI:-0.34 to 0.48;P=0.73).Based on our analysis,probiotic supplements were effective in relieving constipation through symptom improvement.The effectiveness of dosage forms of intervention ranked:capsules>others(tablets,powder)>fermented milk.

Contribution of gut microbiota to drug-induced liver injury

Drug-induced liver injury(DILI)is caused by various drugs with complex pathogenesis,and diverse clinical and pathological phenotypes.Drugs damage the liver directly through drug hepatotoxicity,or indirectly through drug-mediated oxidative stress,immune injury and inflammatory insult,which eventually lead to hepatocyte necrosis.Recent studies have found that the composition,relative content and distribution of gut microbiota in patients and animal models of DILI have changed significantly.It has been confirmed that gut microbial dysbiosis brings about intestinal barrier destruction and microorganisms translocation,and the alteration of microbial metabolites may cause or aggravate DILI.In addition,antibiotics,probiotics,and fecal microbiota transplantation are all emerging as prospective therapeutic methods for DILI by regulating the gut microbiota.In this review,we discussed how the altered gut microbiota participates in DILI.

Expert Consensus on the Diagnosis and Treatment of Anticancer Drug-Induced Interstitial Lung Disease

Drug-induced interstitial lung disease(DILD)is the most common pulmonary adverse event of anticancer drugs.In recent years,the incidence of anticancer DILD has gradually increased with the rapid development of novel anticancer agents.Due to the diverse clinical manifestations and the lack of specific diagnostic criteria,DILD is difficult to diagnose and may even become fatal if not treated properly.Herein,a multidisciplinary group of experts from oncology,respiratory,imaging,pharmacology,pathology,and radiology departments in China has reached the“expert consensus on the diagnosis and treatment of anticancer DILD”after several rounds of a comprehensive investigation.This consensus aims to improve the awareness of clinicians and provide recommendations for the early screening,diagnosis,and treatment of anticancer DILD.This consensus also emphasizes the importance of multidisciplinary collaboration while managing DILD.

Baizhu-Baishao herb pair ameliorates functional constipation and intestinal microflora disorder in rats

Background:In China,Rhizoma atractylodis macrocephalae-Paeonia lactiflora Pall(Biazhu-Baishao,BZBS)is a classic herb pair used to treat intestinal stress syndrome,ulcerative colitis and other diseases.However,the mechanism of BZBS in the treatment of functional constipation(FC)has been little studied and remains unclear.In this study,a behavioral investigation,colon tissue morphology,enzyme-linked immunosorbent assay(Elisa)and intestinal microflora analysis have been used to illuminate the potential mechanism of the effects of BZBS on FC in a rat model.Methods:A FC rat model was constructed and BZBS was given as treatment.Observations and recordings were made of the fecal moisture content,the defecation time of the first black stool,and the rate of intestinal propulsion.Elisa was used to detect the expression levels of substance P(SP),vasoactive intestinal peptide(VIP),5-hydroxytryptamine(5-HT)in the colon.To ascertain the composition of the microbial community,a high throughput 16S ribosomal RNA(16S r RNA)gene sequencing technique was employed.Results:Oral administration of BZBS significantly ameliorated several key excretion parameters,including the time to first black stool defecation,stool water content,and the propulsion rate in the small intestine in FC rats.It increased the expression of SP,VIP and 5-HT in the colon.16S r RNA gene sequencing results showed that BZBS changed the microbial community structure,decreased the Bacteroidetes/Firmicutes ratio,increased the relative abundance of Blautia and Fusicatenibacter,and decreased the relative abundance of Ruminococcus and Roseburia.Conclusions:BZBS effectively alleviates FC and improves dysbacteriosis.

Cinnamic acid regulates the intestinal microbiome and short-chain fatty acids to treat slow transit constipation

BACKGROUND Slow transit constipation(STC)is a disorder with delayed colonic transit.Cinnamic acid(CA)is an organic acid in natural plants,such as Radix Scrophulariae(Xuan Shen),with low toxicity and biological activities to modulate the intestinal microbiome.AIM To explore the potential effects of CA on the intestinal microbiome and the primary endogenous metabolites-short-chain fatty acids(SCFAs)and evaluate the therapeutic effects of CA in STC.METHODS Loperamide was applied to induce STC in mice.The treatment effects of CA on STC mice were assessed from the 24 h defecations,fecal moisture and intestinal transit rate.The enteric neurotransmitters:5-hydroxytryptamine(5-HT)and vasoactive intestinal peptide(VIP)were determined by the enzyme-linked immunosorbent assay.Hematoxylin-eosin and Alcian blue and Periodic acid Schiff staining were used to evaluate intestinal mucosa's histopathological performance and secretory function.16S rDNA was employed to analyze the composition and abundance of the intestinal microbiome.The SCFAs in stool samples were quantitatively detected by gas chromatography-mass spectrometry.RESULTS CA ameliorated the symptoms of STC and treated STC effectively.CA ameliorated the infiltration of neutrophils and lymphocytes,increased the number of goblet cells and acidic mucus secretion of the mucosa.In addition,CA significantly increased the concentration of 5-HT and reduced VIP.CA significantly improved the diversity and abundance of the beneficial microbiome.Furthermore,the production of SCFAs[including acetic acid(AA),butyric acid(BA),propionic acid(PA)and valeric acid(VA)]was significantly promoted by CA.The changed abundance of Firmicutes,Akkermansia,Lachnoclostridium,Monoglobus,UCG.005,Paenalcaligenes,Psychrobacter and Acinetobacter were involved in the production of AA,BA,PA and VA.CONCLUSION CA could treat STC effectively by ameliorating the composition and abundance of the intestinal microbiome to regulate the production of SCFAs.

Drug-induced entero-colitis due to interleukin-17 inhibitor use;capsule endoscopic findings and pathological characteristics:A case report

BACKGROUND Interleukin-17(IL-17)inhibitors are known to cause exacerbation or new onset of inflammatory bowel disease upon administration.However,few reports have described characteristic endoscopic and histopathologic findings,and no small intestinal lesions have been reported so far.CASE SUMMARY A woman in her 60s with psoriasis was administered ixekizumab(IXE),an anti-IL-17A antibody,for the treatment of psoriasis.Twenty months after commencing treatment,the patient visited our hospital because of persistent diarrhea.Blood tests performed at the time of the visit revealed severe inflammation,and colonoscopy revealed multiple round ulcers throughout the colon.A tissue biopsy of the ulcer revealed infiltration of inflammatory cells and granuloma-like findings in the submucosal layer.Capsule endoscopy revealed multiple jejunal erosions.After the withdrawal of IXE,the symptoms gradually improved,and ulcer reduction and scarring of the colon were endoscopically confirmed.CONCLUSION To the best of our knowledge,17 reports have documented IL-17 inhibitorinduced entero-colitis with endoscopic images,endoscopic findings,and pathological characteristics,including the present case.Nine of these cases showed diffuse loss of vascular pattern,coarse mucosa/ulcer formation in the left colon,and endoscopic findings similar to those of ulcerative colitis.In the remaining eight cases,discontinuous erosions and ulcerations from the terminal ileum to the rectum were seen,with endoscopic findings similar to those of Crohn’s disease.In this case,the findings were confirmed by capsule endoscopy,which has not been previously reported.

Association Between Constipation and a Reduction in Lower Limb Muscle Strength in Preoperative Patients with Thoracic Spinal Tumors

Objective To investigate the clinical symptoms experienced by patients with thoracic spinal tumors and verify the associated symptoms that are predictive of a decline in muscle strength in the lower limbs.Methods A single-center,retrospective cross-sectional study was conducted on in-patients diagnosed with epidural thoracic spinal tumors between January 2011 and May 2021.The study involved a review of electronic medical records and radiographs and the collection of clinical data.The differences in clinical manifestations between patients with constipation and those without constipation were analyzed.Binary logistic regression analyses were performed to identify risk factors associated with a decline in muscle strength in the lower limbs.Results A total of 227 patients were enrolled,including 131 patients with constipation and 96 without constipation.The constipation group had a significantly higher proportion of patients who experienced difficulty walking or paralysis compared to those without constipation prior to surgery(83.2%vs.17.7%,χ~2=99.035,P 0.001).Constipation(OR=9.522,95%CI:4.150±21.849,P 0.001)and urinary retention(OR=14.490,95%CI:4.543±46.213,P 0.001)were independent risk factors for muscle strength decline in the lower limbs.Conclusions The study observed that patients with thoracic spinal tumors who experienced constipation symptoms had a higher incidence of lower limb weakness.Moreover,the analysis revealed that constipation and urinary retention were independent risk factors associated with a preoperative decline in muscle strength of lower limbs.
