Lenalidomide-related diarrhea is associated with gut microbiota dysbiosis and disruption of the bile acid pool (ASH 2025) - P2 | "Symptom responsiveness to BA binders (colesevelam)has been described (PMID: 39300066), but the underlying mechanism of LRD is not known. We reveal primaryBA enrichment in patients with LRD, which correlated with disrupted microbial processing capacity. Thesedata suggest that beyond bile acid sequestration, strategies to improve gut microbial diversity andfunctional capacity may warrant further study for mitigation of LRD."

Lipid-Lowering Therapy Is Underutilized Across LDL-C Levels in Autoimmune Disease Compared to Diabetes: A Nationwide Analysis (AHA 2025) - "Statins included atorvastatin, rosuvastatin, simvastatin, pravastatin, lovastatin, fluvastatin, pitavastatin. Non-statin therapies included icosapent ethyl, colesevelam, alirocumab, evolocumab, Bempedoic acid, cholestyramine, Inclisiran, colestipol, ezetimibe, gemfibrozil, omega-3 acid, fenofibrate...Non-statin lipid-lowering therapy use was significantly lower in autoimmune patients compared to those with diabetes across all LDL-C tertiles, with the largest differences observed at LDL <70 mg/dL (6.19% vs 10.24%, p<0.0001) and 70–99 mg/dL (4.05% vs 7.06%, p<0.0001).ConclusionDespite comparable ASCVD risk, patients with autoimmune disease are significantly less likely to receive statins or non-statin lipid-lowering therapy than those with DM across LDL-C levels. These findings show a need for improved cardiovascular prevention in this high-risk population."

Refractory Collagenous Colitis Requiring Inpatient Infliximab Infusion (ACG 2025) - "Multiple therapies, including loperamide, diphenoxylate-atropine, budesonide, bismuth subsalicylate, cholestyramine, colesevelam, mesalamine, gluten-free diet, and recent initiation of prednisone with azathioprine for the current flare have been ineffective. Attempts to initiate outpatient biologic therapy, with infliximab or vedolizumab, were unsuccessful due to insurance denial...TPN was started and trials of octreotide and rifaximin yielded no improvement...Severity and chronicity of microscopic colitis may mimic that of inflammatory bowel disease, and biologic therapy such as TNF-α inhibitors may be used for treatment, although current knowledge is based on case reports and studies. Further research is needed to investigate the role, safety and efficacy of biologics for treating microscopic colitis, which may help streamline off-label treatments, decrease morbidity, improve barriers for initiating such medications and resource utilization."

Bile Acid Sequestrant-Induced Hypertriglyceridemia Leading to Acute Pancreatitis: A Case Report (ACG 2025) - "Although effective for gastrointestinal symptoms, they can affect lipid metabolism and pre-dispose one to consequences of hypertriglyceridemia.Case Description/ A 58-year-old Caucasian male with a history of ileocolonic Crohn's disease status post-surgical resection on ustekinumab was prescribed colesevelam for bile acid diarrhea which provided subsequent relief. Despite this, routine triglyceride screening is not standard before initiating bile acid sequestrant therapy for bile acid diarrhea. Given the prevalence of hypertriglyceridemia and reports of pancreatitis likely triggered by bile acid sequestrants, we recommend triglyceride screening in all patients with bile acid diarrhea prior to initiating bile acid sequestrant therapy."

ASSOCIATION BETWEEN PRURITUS AND HEALTHCARE UTILIZATION AND COSTS AMONG INDIVIDUALS WITH PRIMARY BILIARY CHOLANGITIS IN THE UNITED STATES (AASLD 2025) - "Subgroup analyses required pruritus treatment (sertraline, naltrexone, cholestyramine, cholestipol, rifampin, colesevelam, hydroxyzine or diphenhydramine) within ±90 days of the index date. Eligibility included age >=18, continuous enrollment for >=12 months pre- and post-index date, excluding patients receiving obeticholic acid during baseline... In a real-world study of patients with PBC, pruritus was a significant contributor to HCRU and costs. These findings highlight the need for effective management and novel therapies to alleviate pruritus and reduce its associated clinical burden and costs."

UTILIZATION OF SEHCAT [75SE-TAUROSELCHOLIC ACID] SCANNING FOR DIAGNOSING BILE ACID MALABSORPTION IN A UK TERTIARY REFERRAL CENTRE: AN UNDERUTILIZED DIAGNOSTIC TOOL FOR ENHANCING THE MANAGEMENT OF CHRONIC DIARRHOEA [WITHDRAWN] (UEGW 2025) - "SeHCAT scans demonstrated a diagnostic yield of 41.6% for BAM in a cohort of 334 patients, with 62.5% of assessed cases achieving a clinical response to bile acid sequestrant therapy (cholestyramine or colesevelam). These findings underscore the utility of SeHCAT scanning as a highly sensitive and specific tool for identifying BAM, a frequently underdiagnosed contributor to chronic diarrhea. Given the variability in current clinical practice and the underutilization of this diagnostic modality, integrating SeHCAT scans into standardized diagnostic algorithms for chronic diarrhea is recommended to enhance diagnostic accuracy and optimize patient outcomes."

MANAGEMENT OF BILE ACID MALABSORPTION: INSIGHTS INTO TREATMENT AND PATIENT OUTCOMES (UEGW 2025) - "Current first-line treatment involves bile acid sequestrants (eg.cholestyramine, colesevelam).

Poor compliance with cholestyramine, primarily due to side effects, underscores the importance of individualized treatment plans and patient education. Furthermore, inadequate follow-up care likely contributed to suboptimal treatment outcomes."

Developing a novel diagnostic method for bile acid malabsorption using liquid chromatography-mass spectrometry (BSG 2025) - "Whereas, in idiopathic BAM patients, levels of both lithocholic acid and chenodeoxycholic acid were significantly higher after treatment with colesevelam compared with those before treatment (p<0.01)...The significant differences in bile acid levels between disease groups suggest that the disease groups can be distinguished using their bile acid profiles, therefore providing a potential diagnostic tool for BAM. Ongoing research is focused on comparing the current bile acid data to the SeHCAT diagnostic data."

Management of bile acid malabsorption: insights into treatment and patient outcomes (BSG 2025) - "Current first-line treatment involves bile acid sequestrants (eg.cholestyramine, colesevelam). Co-prescribing antidiarrhoeals alongside sequestrants showed promising efficacy and tolerability, potentially reducing the need for higher doses of sequestrants and their associated side effects. These findings call for improved follow-up protocols, patient-centered approaches to medication management, and further exploration of combination therapies to enhance outcomes in BAM management."

Bile Acid Binding Resins Improve Glucagon Receptor Agonist-Mediated Weight Loss in Diet-Induced Obese Mice (ADA 2025) - "These findings led us to hypothesize that BA-signaling is a key component of GCGR-stimulated weight loss and that BA sequestration may reduce this effect. To evaluate this hypothesis, we utilized BA-binding resins (BARS; Colesevelam (Colsv) and Cholestyramine (Cstyr)) to prevent intestinal BA re-uptake... Collectively, these studies suggest that BARS may enhance the anti-obesity effect of GCGR agonism and beneficially regulate feeding behavior in DIO mice. Furthermore, these studies argue that GCGR agonism combined with BARS treatment may represent a novel supplemental therapeutic approach for treatment of obesity."
