Approximately 80% of patients undergoing chemotherapeutic treatment for colorectal and other gastrointestinal cancers present with CID;moreover, about 5% of early deaths associated with combination anti-cancer chemotherapy are due to CID. Chronic post-treatment diarrhoea amongst cancer survivors can persist for more than 10 years greatly effecting long-term quality of life. Gastrointestinal toxicities such as diarrhoea and vomiting are amongst the primary contributors to dose reductions and delays throughout anti-cancer treatment, presenting a significant hurdle in clinical management of anti-cancer regimes and often result in sub-optimum treatment. However, little is known about pathophysiological mechanisms underlying CID. This work provides a review of chemotherapy-induced diarrhoea, current management guidelines, and shortcomings of current treatments as well as emerging and already existing anti-diarrhoeal treatments potentially suitable for CID.展开更多

Methods: A retrospective study was conducted on data from 358 patients with lung cancer who received chemotherapy. Results: Among 358 cases of lung cancer who received chemotherapy, a total of 240 patients experienced CIL, rate was 67%. The demographic data including gender (P = 0.795), age (P = 0.134), presence of selected chronic comorbidities (P = 0.23) were not significantly different in the two groups. The weight loss rate, PS score, sub-normal pre-WBC level, sub-normal pre-PLT level, and the cycle of chemotherapy were significantly different between the groups (P < 0.05). Multivariate analysis revealed that the weight loss rate ≥5% (OR = 0.503), sub-normal pre-WBC level (OR = 11.807), the cycle of chemotherapy ≥3 (OR = 3.100) were main risk factors for CIL in lung cancer. Conclusion: Before treatment, weight loss rate is 5% or higher, chemotherapy has a cycle of 3 or more and sub-normal WBC level is independent risk factor of lung cancer after chemotherapy-induced leucopenia.展开更多

Neurokinin-1 receptor antagonists (NK1-RAs) have been incorporated in the contemporary management of CINV. However, clinical studies on NK1-RAs have shown mixed results in reducing CINV risk. Most studies focused on the use of aprepitant (APR) and casopitant (CAS) in breast cancer patients receiving AC-type (doxorubicin and cyclophosphamide) chemotherapy. In this study, we compared the study design and clinical efficacies of these NK1-RAs in reducing CINV risk. Among the selected eight studies, 4 APR Randomized Controlled Trials (RCTs), 2 APR Observational Studies (OSs) and 2 CAS RCTs were identified. Patient-related characteristics such as the proportion of females (60.0% - 100.0%), age (46.5 - 59.5 years), histories of motion (5.6% - 47.0% in NK1-RA arms) and morning sicknesses (14.2% - 45.0% in NK1-RA arms) and types of antiemetic regimens;as well as chemotherapy-related characteristics such as the proportion of patients on AC chemotherapy (15.0% - 100.0%) varied greatly. In terms of efficacies, both APR and CAS improved overall CR and vomiting in majority of the studies. None of the studies, however, demonstrated that NK1-RA could provide adequate nausea control. To conclude, NK1-RAs are effective in improving vomiting and overall CR, but not useful in controlling nausea or attaining CC, the ideal CINV endpoint. A shift in paradigm is needed for future CINV research. As healthcare providers continue to strive for optimum CINV control in their patients, we hope this review can help them make better informed clinical decisions.展开更多

Methods: In Experiment 1, six healthy beagles were administered the protocol-approved dose of the electrolyte solution to evaluate clinical, biochemical, or fecal microbiome changes. In Experiment 2, 22 dogs with small or large bowel diarrhea were randomized into one of three groups: the electrolyte solution and a prescription veterinary diet, a placebo and a prescription veterinary diet, or the electrolyte solution and a standard diet. A fecal score was assigned by trained, masked observers through Day 5 using the Purina 7-point fecal scoring system. All dogs were screened for enteric parasites by fecal flotation and the use of a fluorescence antibody assay for Giardia spp. cysts and Cryptosporidium spp. oocysts and all dogs that were parasitized were administered fenbendazole for five days. Results: In Experiment 1, all dogs tolerated the electrolyte solution with no vomiting or diarrhea noted and there was no evidence of negative effects on the gastrointestinal microbiome. In Experiment 2, 16 of the 22 dogs enrolled in the study had a normal stool the day after the first dose of the electrolyte solution, prescription diet, or placebo. All six dogs with the first day of normal stool detected after Day 1 were parasitized. When the days to normalcy were compared, the parasitized dogs had a significantly slower resolution (P = 0.018) than dogs with no parasites regardless of the other treatment group. Conclusions and Relevance: The results of the study suggest that this electrolyte solution is safe for use in dogs and that adding the electrolyte solution to a standard diet is equivalent to using a therapeutic diet alone or the electrolyte solution combined with a therapeutic diet.展开更多

文摘Background:Liu-Jun-Zi decoction(LJZD),a classical nourishing formula in China,has been proven to be effective in treating chemotherapy-induced anorexia.In this study,the mechanism of LJZD in alleviating chemotherapy-induced anorexia was discussed from the aspects of regulating gut microbiota,repairing intestinal barrier injury and inhibiting inflammatory pathways.Methods:A rat model of chemotherapy-induced anorexia was established using cisplatin.The study evaluated the therapeutic effects of LJZD by observing the weight,food intake,and intestinal pathology of rats.The impact of LJZD on gut microbiota and metabolites,specifically short-chain fatty acids,was investigated through gut microbiota analysis and targeted metabolomics.The anti-inflammatory and intestinal protective effects of LJZD were assessed by examining the expression of intestinal tight junction proteins associated with the inflammatory pathway.Results:LJZD alleviated cisplatin-induced inflammation and intestinal barrier disruption,as evidenced by upregulated expression of tight junction protein 1(TJ-1)and occludin,along with reduced serum levels of interleukin 6(IL-6),interleukin-1β(IL-1β),tumor necrosis factor-α(TNF-α),and lipopolysaccharide.Additionally,LJZD alleviated microbiota imbalance and regulated the levels of short-chain fatty acids,especially increased the relative abundance of Coriobacteriales Incertae Sedis,Lactabacillus johnsonii F19785,Parasutterella,and reduced the Tyzzerella.In the hypothalamus,LJZD exerts suppressive effects on the toll-like receptor 4(TLR4)/myeloid differentiation factor 88(MyD88)/nuclear factor-κB(NF-κB)p65 signaling pathway,leading to a downregulation in the transcriptional activity of IL-6 and IL-1β,as well as Interleukin 6 receptors(IL-6R)and Interleukin-1βreceptors(IL-1R1)mRNA expression levels.Conclusion:In summary,LJZD alleviate chemotherapy-induced anorexia by modulating the gut microbiota,repairing the intestinal mechanical barriers,and suppressing the TLR4/MyD88/NF-κB p65 signaling pathway.

文摘BACKGROUND Enterotoxins produce diarrhea through direct epithelial action and indirectly by activating the enteric nervous system.Calcium-sensing receptor(CaSR)inhibits both actions.The latter has been well documented in vitro but not in vivo.The hypothesis to be tested was that activating CaSR inhibits diarrhea in vivo.AIM To determine whether CaSR agonists ameliorate secretory diarrhea evoked by cholera toxin(CTX)in mice.METHODS CTX was given orally to C57BL/6 mice to induce diarrhea.Calcium and calci-mimetic R568 were used to activate CaSR.To maximize their local intestinal actions,calcium was administered luminally via oral rehydration solution(ORS),whereas R568 was applied serosally using an intraperitoneal route.To verify that their actions resulted from the intestine,effects were also examined on Cre-lox intestine-specific CaSR knockouts.Diarrhea outcome was measured biochemically by monitoring changes in fecal Cl-or clinically by assessing stool consistency and weight loss.RESULTS CTX induced secretory diarrhea,as evidenced by increases in fecal Cl-,stool consistency,and weight loss following CTX exposure,but did not alter CaSR,neither in content nor in function.Accordingly,calcium and R568 were each able to ameliorate diarrhea when applied to diseased intestines.Intestinal CaSR involvement is suggested by gene knockout experiments where the anti-diarrheal actions of R568 were lost in intestinal epithelial CaSR knockouts(villinCre/Casrflox/flox)and neuronal CaSR knockouts(nestinCre/Casrflox/flox).CONCLUSION Treatment of acute secretory diarrheas remains a global challenge.Despite advances in diarrhea research,few have been made in the realm of diarrhea therapeutics.ORS therapy has remained the standard of care,although it does not halt the losses of intestinal fluid and ions caused by pathogens.There is no cost-effective therapeutic for diarrhea.This and other studies suggest that adding calcium to ORS or using calcimimetics to activate intestinal CaSR might represent a novel approach for treating secretory diarrheal diseases.
文摘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.
文摘Irritable bowel syndrome with diarrhea is a very frequent clinical condition characterized by disabling intestinal symptoms.This disease presents with daily abdominal pain for at least 3 months related to defecation and associated with a change in the frequency of bowel movements and the shape of the stool.International surveys about this disease report a global prevalence of about 1.5%.A new amino acid based electrolyte solution has recently been commercialized for oral rehydration in diarrhea.It is composed of water,electrolytes,and five selected amino acids that function as sodium co-transporters without containing glucose.In recent years,some studies explored the effectiveness of the amino acid based electrolyte beverage in oncologic patients with gastrointestinal mucositis,reporting good results.Recently,a prospective study to evaluate the clinical impact of the amino acid based medical beverage was conducted in patients with diarrhea predominant irritable bowel syndrome.The research was based on a real-life methodology minimizing the disruption of the routine care.One hundred patients suffering from irritable bowel syndrome with diarrhea drank a solution based on selected amino acids twice a day for 2 wk.Each enrolled patient completed the study and showed a significant response rate with regard to stool consistency and pain reduction.Based on this data,we can hypothesize that the amino acid based oral rehydration solution could be a valid tool in the treatment of patients affected by irritable bowel syndrome with diarrhea.It is certainly necessary to plan highquality clinical trials comparing glucose based oral solutions and amino acid based solutions in patients with persisting diarrhea.Probably in the near future all oral rehydration solutions will contain amino acids.
文摘Cancer stands as one of the major threats to human life.Ensuring the safety of drugs is paramount,and the impact of adverse reactions on patients’quality of life and prognosis should not be underestimated.Diarrhea is a common clinical adverse event,and despite the absence of specific anti-diarrhea drugs,there is a pressing need for improvement.This article aims to provide a valuable reference for researchers in clinical drug use and scientific tumor treatment.It summarizes recent advancements in drug mechanisms and adverse reactions,whether in preclinical research or clinical diagnosis and therapy.
文摘Chemotherapy-induced diarrhoea (CID) is a common side-effect experienced by patients being treated with a variety of antineoplastic agents. Approximately 80% of patients undergoing chemotherapeutic treatment for colorectal and other gastrointestinal cancers present with CID;moreover, about 5% of early deaths associated with combination anti-cancer chemotherapy are due to CID. Chronic post-treatment diarrhoea amongst cancer survivors can persist for more than 10 years greatly effecting long-term quality of life. Gastrointestinal toxicities such as diarrhoea and vomiting are amongst the primary contributors to dose reductions and delays throughout anti-cancer treatment, presenting a significant hurdle in clinical management of anti-cancer regimes and often result in sub-optimum treatment. However, little is known about pathophysiological mechanisms underlying CID. This work provides a review of chemotherapy-induced diarrhoea, current management guidelines, and shortcomings of current treatments as well as emerging and already existing anti-diarrhoeal treatments potentially suitable for CID.

文摘Chemotherapy-induced neutropenia(CIN)is a potentially fatal and common complication in myelosuppressive chemotherapy.The timing and grade of CIN may play prognostic and predictive roles in cancer therapy.CIN is associated with older age,poor functional and nutritional status,the presence of significant comorbidities,the type of cancer,previous chemotherapy cycles,the stage of the disease,specific chemotherapy regimens,and combined therapies.There are many key points and new challenges in the management of CIN in adults including:(1)Genetic risk factors to evaluate the patient’s risk for CIN remain unclear.However,these risk factors urgently need to be identified.(2)Febrile neutropenia(FN)remains one of the most common reasons for oncological emergency.No consensus nomogram for FN risk assessment has been established.(3)Different assessment tools[e.g.,Multinational Association for Supportive Care in Cancer(MASCC),the Clinical Index of Stable Febrile Neutropenia(CISNE)score model,and other tools]have been suggested to help stratify the risk of complications in patients with FN.However,current tools have limitations.The CISNE score model is useful to support decision-making,especially for patients with stable FN.(4)There are still some challenges,including the benefits of granulocyte colony stimulating factor treatment and the optimal antibiotic regimen in emergency management of FN.In view of the current reports,our group discusses the key points,new challenges,and management of CIN.
文摘Chemotherapy-induced peripheral neuropathy(CIPN)is a common side effect that occurs in 20%of ovarian cancer patients treated with the combination of carboplatin/paclitaxel(CP).This toxicity is directly correlated with the dose of paclitaxel administered.Several studies have investigated whether different formulations of taxane can induce this side effect at a lower rate,but,unfortunately,no significant improvement was obtained.CIPN can be disabling in the daily lives of patients and can cause dose reduction or early termination of the treatment.Neuropathy can last for months and even years after its onset.Moreover,patients responsive to CP treatment are candidates for a reintroduction of the same drugs when disease relapse occurs,and residual neuropathy can affect the continuation of treatment.There are no approved drugs that mitigate or prevent the onset of CIPN.In this review,we summarize the evidence regarding the incidence of CIPN with different taxane formulations,regimen schedules and prevention systems.In particular,the Hilotherm®Chemo care device is a regional cooling system that lowers the temperature of the hands and feet to reduce the flow of chemotherapy into the capillaries.We used hilotherapy during chemotherapy infusion to prevent the onset of CIPN.Updated data from 44 ovarian cancer patients treated with 6 cycle of CP show that hilotherapy was well tolerated;only two patients(4.5%)stopped hilotherapy because of cold intolerance,and only one patient(2.2%)experienced grade≥2 CIPN.

文摘BACKGROUND Chemotherapy-induced peripheral neuropathy(CIPN)is a severe and longlasting side effect caused by various anticancer agents that damage sensory,motor and autonomic nerves.It can cause maladaptive behaviors,including disease severity,anxiety,depression,sleep disorders,falls,and social impairment.These disorders have physical,psychological and social effects on patients and can seriously influence their quality of life.AIM To investigate the current situation of psychosocial adaptation to the disease and its influencing factor in patients with CIPN.METHODS A convenience sampling method was used to select 233 patients with CIPN in our hospital from February to August 2021.In addition,a cross-sectional survey was conducted using a sociodemographic questionnaire,the Self-Report Psychosocial Adjustment to Illness Scale,and the European Organisation for the Research and Treatment of Cancer Quality of Life CIPN20(QLQ-CIPN20).Factors influencing psychosocial adaptation in patients with CIPN were analyzed by t-test or one-way analysis of variance,correlation analysis,multiple stepwise regression analysis,and structural equation models.RESULTS The psychosocial adaptation score of patients with CIPN was 52.51±13.18.Multivariate analysis showed that autonomic nerves,tumor stage,motor nerves,education level,availability of caregivers,semi-retirement status,CIPN grade were independent risk factors for patients with CIPN(P<0.05).Structural equation models showed that QLQ-CIPN20 mediated the relationship between CIPN grade,tumor stage,and psychosocial adaptation.CONCLUSION Patients with CIPN have poor psychosocial adaptation and are affected by a variety of physiological,psychological,and social factors.Patients’adaptive responses should be assessed,and targeted interventions implemented.

文摘Background:Diarrhea is a major cause of morbidity and mortality in young calves,resulting in considerable economic loss for dairy farms.To determine if some gut microbes might have resistance to dysbiotic process with calf diarrhea by dictating the microbial co-occurrence patterns from birth to post-weaning,we examined the dynamic development of the gut microbiota and diarrhea status using two animal trials,with the first trial having 14 Holstein dairy calves whose fecal samples were collected 18 times over 78 d from birth to 15 d post-weaning and the second trial having 43 Holstein dairy calves whose fecal samples were collected daily from 8 to 18 days of age corresponding to the first diarrhea peak of trial 1.Results:Metataxonomic analysis of the fecal microbiota showed that the development of gut microbiota had three age periods with birth and weaning as the separatrices.Two diarrhea peaks were observed during the transition of the three age periods.Fusobacteriaceae was identified as a diarrhea-associated taxon both in the early stage and during weaning,and Clostridium_sensu_stricto_1 was another increased genus among diarrheic calves in the early stage.In the neonatal calves,Prevotella_2(ASV4 and ASV26),Prevotella_9(ASV43),and Alloprevotella(ASV14)were negatively associated with Clostridium_sensu_stricto_1(ASV48),the keystone taxa of the diarrhea-phase module.During weaning,unclassified Muribaculaceae(ASV28 and ASV44),UBA1819(ASV151),Barnesiella(ASV497),and Ruminococcaceae_UCG-005(ASV254)were identified being associated with non-diarrheic status,and they aggregated in the non-diarrhea module of co-occurrence patterns wherein unclassified Muribaculaceae(ASV28)and Barnesiella(ASV497)had a direct negative relationship with the members of the diarrhea module.Conclusions:Taken together,our results suggest that the dynamic successions of calf gut microbiota and the interactions among some bacteria could influence calf diarrhea,and some species of Prevotella might be the core microbiota in both neonatal and weaning calves,while species of Muribaculaceae might be the core microbiota in weaning calves for preventing calf diarrhea.Some ASVs affiliated with Prevotella_2(ASV4 and ASV26),Prevotella_9(ASV43),Alloprevotella(AVS14),unclassified Muribaculaceae(ASV28 and ASV44),UBA1819(ASV151),Ruminococcaceae_UCG-005(ASV254),and Barnesiella(ASV497)might be proper probiotics for preventing calf diarrhea whereas Clostridium_sensu_stricto_1(ASV48)might be the biomarker for diarrhea risk in specific commercial farms.

文摘Background:This study aimed to investigate the hydration properties of different-source fibrous materials by com-paring their water-binding capacity(WBC),water swelling capacity(WSC),viscosity,and in vivo effects of selected samples on growth performance,nutrient digestibility,diarrhea,and intestinal health in weaned piglets.Methods:A total of 13 commercially available fibrous materials were first compared in chemical composition and in vitro hydration property.Subsequently,40 weaned piglets were randomized to five experimental dietary groups(8 piglets per group):control diet(a basal diet without dietary fiber,CON),basal diet supplemented with 5%microcrys-talline cellulose(MCC),5%wheat bran(WB),5%Moringa oleifera leaf powder(MOLP),or 5%sugar beet pulp(SBP),fol-lowed by analyzing their growth performance and diarrhea rate in a 28-d experiment.After the feeding experiment,anaesthetized piglets were killed,and their intestinal and colon content or plasma samples were analyzed in nutrient digestibility,intestinal morphology,intestinal barrier,short-chain fatty acids(SCFAs),and bacterial population.Results:In vitro studies showed low hydration properties for WB and MCC,while medium hydration properties for MOLP and SBP.In vivo studies indicated that compared with medium hydration property groups,low hydration prop-erty groups showed(1)exacerbated diarrhea,impaired intestinal health,and reduced apparent fecal digestibility of dry matter,gross energy,acid detergent fiber,and neutral detergent fiber;(2)decreased SCFAs concentration and rela-tive levels of Lactobacillus and Bifidobacterium,but increased levels of Escherichia coli and Brachyspira hyodysenteriae in colon contents.Additionally,SBP showed optimal performance in reducing diarrhea and increasing SCFAs produc-tion.Correlation analysis revealed a positive correlation of fiber hydration properties with in vitro SCFAs production,and diarrhea index and nutrient digestibility were negatively and positively correlated with SCFAs levels in the colon contents of weaned piglets,respectively.Conclusions:Different-source dietary fibers varied in their hydration properties and impacts on diarrhea,microbial composition and SCFAs production in weaned piglets.WB and MCC could exacerbate diarrhea and impair nutrient digestibility,probably because their low hydration properties were detrimental to gut microbial homeostasis and fermentation.Our findings provide new ideas for rational use of fiber resources in weaned piglets.
文摘Objective: This analysis was conducted to clarify risk factors for chemotherapy-induced leukopenia (CIL) in lung cancer. Methods: A retrospective study was conducted on data from 358 patients with lung cancer who received chemotherapy. Results: Among 358 cases of lung cancer who received chemotherapy, a total of 240 patients experienced CIL, rate was 67%. The demographic data including gender (P = 0.795), age (P = 0.134), presence of selected chronic comorbidities (P = 0.23) were not significantly different in the two groups. The weight loss rate, PS score, sub-normal pre-WBC level, sub-normal pre-PLT level, and the cycle of chemotherapy were significantly different between the groups (P < 0.05). Multivariate analysis revealed that the weight loss rate ≥5% (OR = 0.503), sub-normal pre-WBC level (OR = 11.807), the cycle of chemotherapy ≥3 (OR = 3.100) were main risk factors for CIL in lung cancer. Conclusion: Before treatment, weight loss rate is 5% or higher, chemotherapy has a cycle of 3 or more and sub-normal WBC level is independent risk factor of lung cancer after chemotherapy-induced leucopenia.
文摘Chemotherapy-induced nausea and vomiting (CINV) are distressing side effects of chemotherapy. Neurokinin-1 receptor antagonists (NK1-RAs) have been incorporated in the contemporary management of CINV. However, clinical studies on NK1-RAs have shown mixed results in reducing CINV risk. Most studies focused on the use of aprepitant (APR) and casopitant (CAS) in breast cancer patients receiving AC-type (doxorubicin and cyclophosphamide) chemotherapy. In this study, we compared the study design and clinical efficacies of these NK1-RAs in reducing CINV risk. Among the selected eight studies, 4 APR Randomized Controlled Trials (RCTs), 2 APR Observational Studies (OSs) and 2 CAS RCTs were identified. Patient-related characteristics such as the proportion of females (60.0% - 100.0%), age (46.5 - 59.5 years), histories of motion (5.6% - 47.0% in NK1-RA arms) and morning sicknesses (14.2% - 45.0% in NK1-RA arms) and types of antiemetic regimens;as well as chemotherapy-related characteristics such as the proportion of patients on AC chemotherapy (15.0% - 100.0%) varied greatly. In terms of efficacies, both APR and CAS improved overall CR and vomiting in majority of the studies. None of the studies, however, demonstrated that NK1-RA could provide adequate nausea control. To conclude, NK1-RAs are effective in improving vomiting and overall CR, but not useful in controlling nausea or attaining CC, the ideal CINV endpoint. A shift in paradigm is needed for future CINV research. As healthcare providers continue to strive for optimum CINV control in their patients, we hope this review can help them make better informed clinical decisions.
文摘Purpose: To determine if a commercially available electrolyte solution is safe and lessens the duration and severity of diarrhea in shelter dogs in stressful situations. Methods: In Experiment 1, six healthy beagles were administered the protocol-approved dose of the electrolyte solution to evaluate clinical, biochemical, or fecal microbiome changes. In Experiment 2, 22 dogs with small or large bowel diarrhea were randomized into one of three groups: the electrolyte solution and a prescription veterinary diet, a placebo and a prescription veterinary diet, or the electrolyte solution and a standard diet. A fecal score was assigned by trained, masked observers through Day 5 using the Purina 7-point fecal scoring system. All dogs were screened for enteric parasites by fecal flotation and the use of a fluorescence antibody assay for Giardia spp. cysts and Cryptosporidium spp. oocysts and all dogs that were parasitized were administered fenbendazole for five days. Results: In Experiment 1, all dogs tolerated the electrolyte solution with no vomiting or diarrhea noted and there was no evidence of negative effects on the gastrointestinal microbiome. In Experiment 2, 16 of the 22 dogs enrolled in the study had a normal stool the day after the first dose of the electrolyte solution, prescription diet, or placebo. All six dogs with the first day of normal stool detected after Day 1 were parasitized. When the days to normalcy were compared, the parasitized dogs had a significantly slower resolution (P = 0.018) than dogs with no parasites regardless of the other treatment group. Conclusions and Relevance: The results of the study suggest that this electrolyte solution is safe for use in dogs and that adding the electrolyte solution to a standard diet is equivalent to using a therapeutic diet alone or the electrolyte solution combined with a therapeutic diet.
