Abstract
Even though pruritus affects a significant number of people with chronic disease, it is rarely adequately treated. Drug therapies often rely on antihistamines, which have not shown to be beneficial in systemic pruritus. Hydroxyzine is frequently used to treat pruritus associated with kidney failure. Since Canada's sole manufacturer of hydroxyzine is no longer making this product, this is an ideal time to review the mechanisms of itch in advanced organ failure and the specific therapies that give relief. Although there is literature describing itch in patients with cancer, this article is limited to pathogenesis and treatment of systemic itch secondary to chronic, noncancer diseases. We summarize recent systematic reviews, although the studies included in these reviews are often small, and mostly cohort studies.

Hof WFJ, de Boer JF, Verkade HJ. Emerging drugs for the treatment of progressive familial intrahepatic cholestasis: a focus on phase II and III trials. Expert Opin Emerg Drugs 2024:1-16. [PMID: 38571480 DOI: 10.1080/14728214.2024.2336986] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Accepted: 03/27/2024] [Indexed: 04/05/2024]
Abstract
INTRODUCTION Progressive familial intrahepatic cholestasis (PFIC) is a group of disorders characterized by inappropriate bile formation, causing hepatic accumulation of bile acids and, subsequently, liver injury. Until recently, no approved treatments were available for these patients. AREAS COVERED Recent clinical trials for PFIC treatment have focused on intestine-restricted ileal bile acid transporter (IBAT) inhibitors. These compounds aim to reduce the pool size of bile acids by interrupting their enterohepatic circulation. Other emerging treatments in the pipeline include systemic IBAT inhibitors, synthetic bile acid derivatives, compounds targeting bile acid synthesis via the FXR/FGF axis, and chaperones/potentiators that aim to enhance the residual activity of the mutated transporters. EXPERT OPINION Substantial progress has been made in drug development for PFIC patients during the last couple of years. Although data concerning long-term efficacy are as yet only scarcely available, new therapies have demonstrated robust efficacy in a considerable fraction of patients at least on the shorter term. However, a substantial fraction of PFIC patients do not respond to these novel therapies and thus still requires surgical treatment, including liver transplantation before adulthood. Hence, there is still an unmet medical need for long-term effective medical, preferably non-surgical, treatment for all PFIC patients.

Vyas K, Maheshwari K, Reddy PKS, Verma R, Hasan I, Mittal A. Prescription Practices Regarding the use of Systemic Drugs in the Management of Patients with Chronic Pruritus amongst Indian Dermatologists - A Questionnaire Based Survey. Indian Dermatol Online J 2024; 15:33-38. [PMID: 38283019 PMCID: PMC10810406 DOI: 10.4103/idoj.idoj_500_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2022] [Revised: 12/13/2022] [Accepted: 12/31/2022] [Indexed: 01/30/2024] Open
Abstract
Background Chronic pruritus poses a significant challenge to treating physicians due to multitude of underlying causes and varying treatment strategies. Several topical, systemic, and physical modalities have been tried with variable success. Prescription practices in chronic pruritus are influenced by differential knowledge and experience of physicians, patient-related factors, and resource availability. Aim The purpose of this survey was to observe the current pattern of practice in Indian dermatologists in the management of chronic pruritus and to identify practice gaps particularly regarding the use of various systemic agents as antipruritics. Materials and Methods A previously validated questionnaire was sent to consultant dermatologists across India between January 2020 and July 2020. The questionnaire was comprised of six questions (multiple-choice questions as well as open-ended questions) regarding the use of antidepressants, cyclic gamma-aminobutyric acid (GABA) analogues, opioid antagonists, antihistamines, and alternate therapies in the management of chronic pruritus. Results A total of 700 dermatologists completed the questionnaire (response rate 70%). Overall, antihistamines were the most common drug prescribed in chronic pruritus (more than 95% respondents). Other systemic agents such as opioid antagonists, gabapentinoids, and antidepressants were prescribed by 22.42%, 71.85%, and 75.29% respondents, respectively, in chronic pruritus as either monotherapy or in combination with antihistamines in specific types of itches. Among antidepressants, tricyclic antidepressants (TCAs) (69.29%) were prescribed most often, followed by selective serotonin reuptake inhibitors (SSRIs) (32.29%) and serotonin and norepinephrine reuptake inhibitors (SNRIs) (9.14%). Other treatment options such as omalizumab, thalidomide, ondansetron, ursodeoxycholic acid (UDCA), and rifampicin were used by 10% respondents to alleviate pruritus in special situations. Conclusion This survey revealed the redundant practice of prescribing antihistamines in chronic pruritus irrespective of etiology among Indian dermatologists. It also revealed a differential approach regarding use of systemic agents such as gabapentinoids, opioid antagonists, and antidepressants, in academic and non-academic institutions. The survey emphasized a barrier in writing prescription of systemic agents such as opioid antagonist and SNRIs due to lack of knowledge and experience, fear of side effects, and inadequate available evidence.

Therapeutic potential of infliximab for pruritus in mice model of cholestasis induced by bile duct ligation: Possible involvement of IL-31. Int Immunopharmacol 2023; 123:110806. [PMID: 37597403 DOI: 10.1016/j.intimp.2023.110806] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2023] [Revised: 08/11/2023] [Accepted: 08/13/2023] [Indexed: 08/21/2023]
Abstract
BACKGROUND Cholestatic pruritus is a distressful sensation that can cause a massive desire of scratching skin. Despite maximum medication therapy, some patients still experience pruritus. In this study, we evaluated the effect of infliximab on cholestatic pruritus induced in mice by bile duct ligation. METHODS Twenty-four balb/c mice were randomly assigned to three groups; sham, control, and treatment. The bile duct ligation procedure was performed on mice in the control and treatment groups. After six days, mice in the treatment group received subcutaneous administration of infliximab, and the next day all mice were subjected to the scratching behavior test. Skin, dorsal root ganglia (DRG), and blood samples of mice were collected and evaluated by histopathological, molecular, and biochemical tests. RESULTS The scratching behavior has significantly decreased in mice with cholestasis after the administration of infliximab. The levels of TNFα, TNFR1, TNFR2, NF-κB, and IL-31were higher in control mice compared to sham. In addition, expression levels of TNFR1, NF-κB, and IL-31 were decreased in the treatment group compared to the controls in skin and DRG, while TNFR2 levels were decreased only in DRG. CONCLUSION Infliximab can block TNFα interaction with receptors and inhibit further inflammatory response. Also, our results suggested that infliximab can suppress IL-31 expression indirectly, which is a well-known cytokine in pruritus pathophysiology Infliximab can be a potential therapeutic approach in resistant pruritus in cholestatic disorders.

Abstract
Background Pruritus is a symptom of several cholestatic liver diseases (CLDs) that can impair health-related quality of life (HRQoL). Despite evidence-based guideline therapy, managing cholestatic pruritus (CP) remains challenging, thus making the need for newer, more effective therapeutic agents more evident. Objective Our study evaluated the efficacy of existing CP therapies. Design Systematic review. Data sources From inception until March 2023, we conducted a comprehensive search of MEDLINE, Cochrane, EMBASE, Scopus, ClinicalTrial.gov, and other sources, including pharmaceutical webpages and conference proceedings published in English that reported on CP interventions. Methods Two reviewers independently conducted screening and full-text review of articles with extraction conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. The methodological quality of studies included in our qualitative synthesis was assessed by using the Cochrane ROBINS-I and ROBINS-II tools for interventional studies and the National Heart, Lung, and Blood Institute Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. The primary outcome assessed in our systematic review was the severity of CP after therapy. Results Of 3293 screened articles, 92 studies were eligible for inclusion in the qualitative synthesis. Some patients' HRQoL improved with evidence-based standard therapy. Others, particularly those with severe and refractory CP, often required conversion to or addition of experimental noninvasive (e.g., ondansetron) or extracorporeal liver support to alleviate CP. In addition, studies investigating a newer class drug, the ileal bile acid transporter inhibitor (IBATi), demonstrate its effectiveness in reducing serum bile acid and alleviating CP with sustained improvement noted in patients with the inherited childhood cholestatic disorders - progressive familial intrahepatic cholestasis and Alagille syndrome. Conclusion Our findings consolidate data on the efficacy of guideline-based approaches and newer therapies for CP. While the initial findings are promising, additional clinical trials will be needed to determine the full extent of IBATi's efficacy and potential use in treating other common CLDs. These results provide a foundation for future research and highlight the need for continued investigation into the management and treatment of CLDs.

Abstract
BACKGROUND AND AIMS Obeticholic acid (OCA) is a farnesoid X receptor agonist used in primary biliary cholangitis (PBC) treatment. Recent studies have expanded OCA use for NASH treatment and results from phase 3 clinical trial have shown beneficial reduction of ≥1 stage of fibrosis with no NASH worsening. However, safety concerns still preside, thus we systematically examine the safety profile of OCA in chronic liver disease. MATERIALS AND METHODS A search was conducted in Medline and Embase databases for OCA randomized controlled trials in chronic liver disease. Binary events were pooled with Paule-Mandel random effects model and proportional events were examined in a generalized linear mixed model with Clopper-Pearson intervals. RESULTS A total of 8 studies and 1878 patients were analyzed. There was a 75% [risk ratio (RR): 1.75, 95% CI: 1.43-2.15, p < 0.01] increased pruritis risk. OCA increased constipation incidence (RR: 1.88, 95% CI: 1.45-2.43, p < 0.01), decreased diarrhea (RR: 0.62, 95% CI: 0.50-0.77, p < 0.01), and increased development of hyperlipidemia (RR: 2.69, 95% CI: 1.85-3.92, p < 0.01) relative to placebo. Sensitivity analysis in NASH-only studies found a dose-dependent effect with pruritis which increases to RR: 3.07 (95% CI: 1.74-5.41) at 25 mg. However, up to 9.98% (95% CI: 5.01%-18.89%) of NAFLD patients with placebo similarly experience pruritis events. Overall, 16.55% (95% CI: 6.47%-36.24%) of patients with NAFLD on OCA experienced pruritis. There was no significant increase in cardiovascular events. CONCLUSIONS OCA may represent the first pharmacological treatment approved for NASH. However, pruritis, constipation, diarrhea, and hyperlipidemia were major events with evident dose-dependent effect that affect tolerability in NASH. Future long-term studies for longitudinal safety events are required.

Abstract
Methods We included 235 patients with chronic extrahepatic cholestasis due to pancreatic cancer, cholangiocarcinoma, or papillary carcinoma. Results GGT was significantly higher in patients without pruritus (median 967, IQR 587-1571) compared to patients with pruritus (median 561 IQR 266-1084 IU/l) (p < 0.01). In contrast, median alkaline phosphatase (AP) was 491 U/L (IQR; 353-684) in patients with pruritus and was not significantly different from 518 U/L (IQR; 353-726) in patients without pruritus (p = 0.524). Direct bilirubin was significantly higher in patients with pruritus compared to patients without pruritus (168 μmol/L (IQR; 95-256) vs. 120 μmol/L (IQR; 56.75-185.5)) (p < 0.01). After correcting for the extent of cholestasis via direct bilirubin, the negative association between GGT and pruritus remained significant and became stronger (p < 0.001). Conclusion Serum GGT activity is inversely associated with the presence of cholestatic itch in patients with chronic extrahepatic cholestasis.

Abstract
Enterohemorrhagic Escherichia coli (EHEC) is one of the most common foodborne pathogens. However, no drug that prevents the severe complications caused by this bacterium has been approved yet. This study showed that a macroporous magnesium oxide (MgO)-templated carbon material (MgOC150) adsorbs Shiga toxins, and Type III secretory EspA/EspB proteins responsible for EHEC pathogenesis, and decreases the extracellular levels of these proteins. On the other hand, this material did not affect the growth of EHEC. Citrobacter rodentium traditionally used to estimate Type III secretion system-associated virulence in mice is highly virulent. The survival period of infected mice was prolonged when MgOC150 was administered. This adsorbent disturbed neither mammalian cells nor normal intestinal bacteria, such as Enterococcus hirae, Lactobacillus acidophilus, and Lactobacillus casei. In contrast, MgOC150 adsorbed antimicrobial agents, including β-lactams, quinolones, tetracyclines, and trimethoprim/sulfamethoxazole. However, fosfomycin and amikacin were not adsorbed. Thus, MgOC150 can be used with fosfomycin and amikacin to treat infections. MgOC150 is used for industrial purposes, such as an electrode catalyst, a bioelectrode, and enzyme immobilization. The study proposed another potential application of MgOC150, assisting anti-EHEC chemotherapy.

Abstract
BACKGROUND Cirrhosis is increasingly common and morbid. Optimal utilisation of therapeutic strategies to prevent and control the complications of cirrhosis are central to improving clinical and patient-reported outcomes. METHODS We conducted a narrative review of the literature focusing on the most recent advances. RESULTS We review the aetiology-focused therapies that can prevent cirrhosis and its complications. These include anti-viral therapies, psychopharmacological therapy for alcohol-use disorder, and the current landscape of clinical trials for non-alcoholic steatohepatitis. We review the current standard of care and latest developments in the management of hepatic encephalopathy (HE), ascites and hepatorenal syndrome. We evaluate the promise and drawbacks of chemopreventative therapies that have been examined in trials and observational studies which may reduce the risk of hepatocellular carcinoma and cirrhosis complications. Finally, we examine the therapies which address the non-pain symptoms of cirrhosis including pruritis, muscle cramps, sexual dysfunction and fatigue. CONCLUSION The improvement of clinical and patient-reported outcomes for patients with cirrhosis is possible by applying evidence-based pharmacotherapeutic approaches to the prevention and treatment of cirrhosis complications.

Abstract
Recent years have seen major advances in our understanding of primary biliary cholangitis, with the condition now renamed to reflect the majority of patients who do not have cirrhosis. Data from large multicentre studies have greatly increased our knowledge of the natural history of primary biliary cholangitis, making the identification of higher risk patients clearer and facilitating the development of new medications. Recent guidelines have emphasised the importance of risk stratification, targeted treatment of symptoms and early prioritisation for second line therapies. The review summarises recent major developments in our understanding of primary biliary cholangitis and its management.

Abstract
Linerixibat, an oral small-molecule ileal bile acid transporter inhibitor under development for cholestatic pruritus in primary biliary cholangitis, was designed for minimal absorption from the intestine (site of pharmacological action). This study characterized the pharmacokinetics, absorption, metabolism, and excretion of [14C]-linerixibat in humans after an intravenous microtracer concomitant with unlabeled oral tablets and [14C]-linerixibat oral solution. Linerixibat exhibited absorption-limited flip-flop kinetics: longer oral versus intravenous half-life (6-7 hours vs. 0.8 hours). The short intravenous half-life was consistent with high systemic clearance (61.9 l/h) and low volume of distribution (16.3 l). In vitro studies predicted rapid hepatic clearance via cytochrome P450 3A4 metabolism, which predicted human hepatic clearance within 1.5-fold. However, linerixibat was minimally metabolized in humans after intravenous administration: ∼80% elimination via biliary/fecal excretion (>90%-97% as unchanged parent) and ∼20% renal elimination by glomerular filtration (>97% as unchanged parent). Absolute oral bioavailability of linerixibat was exceedingly low (0.05%), primarily because of a very low fraction absorbed (0.167%; fraction escaping first-pass gut metabolism (fg) ∼100%), with high hepatic extraction ratio (77.0%) acting as a secondary barrier to systemic exposure. Oral linerixibat was almost entirely excreted (>99% recovered radioactivity) in feces as unchanged and unabsorbed linerixibat. Consistent with the low oral fraction absorbed and ∼20% renal recovery of intravenous [14C]-linerixibat, urinary elimination of orally administered radioactivity was negligible (<0.04% of dose). Linerixibat unequivocally exhibited minimal gastrointestinal absorption and oral systemic exposure. Linerixibat represents a unique example of high CYP3A4 clearance in vitro but nearly complete excretion as unchanged parent drug via the biliary/fecal route. SIGNIFICANCE STATEMENT: This study conclusively established minimal absorption and systemic exposure to orally administered linerixibat in humans. The small amount of linerixibat absorbed was eliminated efficiently as unchanged parent drug via the biliary/fecal route. The hepatic clearance mechanism was mispredicted to be mediated via cytochrome P450 3A4 metabolism in vitro rather than biliary excretion of unchanged linerixibat in vivo.

Abstract
Background Cholestasis patients often suffer from pain desensitization, resulting in serious complications in perioperative period. This study was aim to investigate the mechanism of bilirubin in cholestasis mediating pain desensitization through 5-hydroxytryptamine 3A (5-HT3A ) receptor activation in spinal dorsal horn (SDH). Methods A cholestasis model was established by bile duct ligation (BDL) in rats. Pain thresholds of rats were measured after BDL or intrathecally injecting bilirubin in the presence or absence of agonist (mCPBG) and antagonists (ondansetron, bicuculline, or CGP55845). Expression of 5-HT3 receptors, and the affinity and binding mode of bilirubin to 5-HT3A receptor were determined. Effects of bilirubin on γ-aminobutyric acid (GABA) pathway and the interactions with 5-HT3A receptor were tested. Results Bilirubin was elevated significantly in both serum and CSF in BDL rats, accompanied with the up-regulation of pain thresholds. Both of 5-HT3A receptor and GABA A receptor antagonists could reverse the increased pain threshold in BDL rats. Further, 5-HT3A and GABA A receptor expressions were increased in BDL rats or intervention with bilirubin. Molecular docking suggested that bilirubin entered the hydrophobic pocket pre-formed in 5-HT3A receptor with potential hydrogen bonding. Bilirubin also increased GABA concentrations in CSF and GABAergic spontaneous inhibitory postsynaptic current in spinal cord, and directly induced inward currents in HEK293 cells which were overexpressed 5-HT3A receptor by lentivirus. Conclusion In conclusion, bilirubin induced pain desensitization in cholestasis by activating 5-HT3A receptor in spinal cord. The activation of 5-HT3A receptor might regulate pain threshold by acting on the GABA pathway.

Abstract
End-stage liver disease (ESLD) is an increasingly prevalent condition with high morbidity and mortality, especially for those ineligible for liver transplantation. Patients with ESLD, along with their family caregivers, have significant needs related to their quality of life, and there is increasing attention being paid to integration of palliative care (PC) principles into routine care throughout the disease spectrum. To provide upstream care for these patients and their family caregivers, it is essential for PC providers to understand their complex psychosocial and physical needs and to be aware of the unique challenges around medical decision making and end-of-life care for this patient population. This article, written by a team of liver and PC experts, shares 10 high-yield tips to help PC clinicians provide better care for patients with advanced liver disease.

Abstract
Pruritus is known to be a common complication in hepatitis patients, but the exact frequency and degree are not fully elucidated. Thus, we evaluated pruritus of 450 patients with chronic liver disease at our hospital. Pruritus was observed in 240 (53%) of the patients. Pruritus was significantly associated with males (OR = 1.51, P = 0.038) and patients with alkaline phosphatase (ALP) ≥ 200 U/L (OR = 1.56, P = 0.0495) and was significantly less in HBsAg-positive patients (OR = 0.449, P = 0.004). Seasonally, there was no difference in the frequency of pruritus between summer and winter. Of the 24 refractory pruritus patients treated with nalfurafine, 17 (71%) indicated improvement of itch, which is defined as a decrease in the visual analog scale score ≥ 30 mm. Pruritus was improved by nalfurafine both during daytime and nighttime in the Kawashima’s scores evaluation. All patients who received nalfurafine exhibited improved Kawashima’s scores ≥ 1 point during the daytime or nighttime. In conclusion, pruritus occurred in > 50% of patients with chronic liver disease, and predictors of pruritus were males and ALP ≥ 200 U/L. Nalfurafine may be useful for pruritus, regardless of whether daytime or nighttime.

Abstract
Cholestasis, a condition characterized by an abnormal decrease in bile flow, is accompanied by various symptoms such as pruritus. Although cholestatic pruritus is a prominent condition, its precise mechanisms have largely been elusive. Recently, advancements have been made for understanding the etiology and pathogenesis of cholestatic pruritus. The current review therefore focuses on summarizing the overall progress made in the elucidation of its molecular mechanisms. We have reviewed the available animal models on cholestasis to compare the differences between them, characterized potential pruritogens involved in cholestatic pruritus, and have summarized the receptor and ion channels implicated in the condition. Finally, we have discussed the available treatment options for alleviation of cholestatic pruritus. As our understanding of the mechanisms of cholestatic pruritus deepens, novel strategies to cure this condition are awaited.

Itching of the skin is a particularly unpleasant subjective sensation that causes the need to scratch. Physiological itching occurs in response to environmental irritants (friction, insect crawling, temperature changes, etc.) and disappears after elimination of the cause. Pathological itching is caused by changes in the skin or throughout the body and causes a strong need to get rid of itching by combing or any other method. Itching is a common symptom of local (dermatological) or general (systemic) disease. It can be limited (localized) or diffuse (generalized).One of the causes of itching is often noted endocrine diseases and metabolic disorders: hyper- and hypofunction of the thyroid gland, diabetes mellitus and hyperparathyroidism. In thyroid hyperfunction, generalized (inconstant and little-pronounced) itching of the skin is observed in the clinical picture only in 10 % of patients. It is accepted that itching of the skin in thyrotoxicosis syndrome is due to increased activity of kinin in combination with an increase in major metabolism and an increase in body and skin temperature (123).Itching caused by impaired bile secretion is characteristic of many diseases of the liver: primary biliary cirrhosis, sclerosing cholangitis, viral hepatitis caused by cholestasis medications and other causes of obstructive jaundice. It is in these cases that prurigo is usually generalized, but in some typical cases it is more pronounced on the feet and palms. With this pathology, itching is caused by obstruction of the biliary tract, however, and to this day, no close correlation has been found between serum bilirubin and the severity of itching.If it was previously thought that itching in pathology of the peripheral or central nervous system, such as multiple sclerosis, neuropathy, compression or irritation of nerves (e.g., paraesthetic dorsalgia, brachioradial itching) is also a significant symptom, then modern studies prove that in more cases, itching is not characteristic of most pathologies of the nervous system, so after a detailed anamnesis, examination and initial research, the patient should be referred to a related specialist, except in cases of about obvious postherpetic neuropathy, painless paresthesia, or brachioradial itching, which can often be guided in the provision of primary care.Instead, there are some psychological conditions and a number of psychiatric illnesses (obsessive-compulsive disorders, depression, and parasite illusions) that are most commonly diagnosed with the exclusion method. Neurotic squabbles are scattered on the body of the excorii, covered with scales that may occur in any area of the body that the patient may reach, but are often limited by limbs.

Esmaeili A, Namazi S. Is melatonin effective for pruritus caused by liver disease? Med Hypotheses 2018; 121:177-179.

Abstract
There is still no definitive treatment to relieve pruritus associated with liver disease, because the precise mechanism of itching has not yet been determined. Different mechanisms have been proposed. One recent explanation is thought to be the rise in serum levels of lysophosphatidic acid which is a metabolite of lysophosphatidyl choline conversion by autotaxin enzyme in liver disease is. Over expression of autotaxin which occurs in atopic dermatitis has been shown to be involved in itching pathology. Importantly, gene amplification of autotaxin also occurs in cholestasis. Melatonin has pleiotropic properties such as suppressive effects on serum level of autotaxin which relieves itching of atopic dermatitis. Due to some similarities in mechanism of itching, it is hypothesized that melatonin may improve itching of liver diseases.

Abstract
GSK2330672 is an inhibitor of the ileal bile acid transporter, designed to have minimal systemic exposure, and is under development as a potential therapeutic for pruritus associated with primary biliary cholangitis and other cholestatic liver diseases. A phase 1, double-blind, placebo-controlled, 4-period crossover study was conducted to evaluate the safety, tolerability, and pharmacokinetic/pharmacodynamic characteristics of GSK2330672 in healthy Japanese participants. Sixteen healthy male participants received single oral doses of GSK2330672 (10-180 mg) or placebo in each period. No serious adverse events and no adverse events leading to study discontinuation or withdrawal were reported. Drug-related adverse events reported included gastrointestinal symptoms (mostly diarrhea) and positive fecal occult blood tests, and were all mild and resolved without any interventions. GSK2330672 was undetectable in the majority of participants' plasma. Pharmacodynamic observations included a tendency for total serum bile acids to reduce and for serum 7α-hydroxy-4-cholesten-3-one, a key intermediate of bile acid synthesis, to increase with increasing doses of GSK2330672. In the context of recently published indications of potential efficacy for cholestatic pruritus in non-Japanese populations, these data support further evaluations of GSK2330672 in Japanese patients.

Abstract
Pruritus in autoimmune connective tissue diseases is a common symptom that can be severe and affect the quality of life of patients. It can be related to disease activity and severity or occur independent of the disease. Appropriate therapy to control the itch depends on the etiology, and it is therefore essential to first work-up these patients for the underlying trigger.

Abstract
Introduction Chronic liver disease (CLD)-related pruritus manifests as cholestasis symptoms, which can cause severe itches in the whole body and significantly decrease quality of daily activities and sleep. The actigram, which documents movement by means of an accelerometer, has been demonstrated to be useful for assessing sleep quality. Nalfurafine hydrochloride, which is a selective κ-opioid receptor agonist, exerts its antipruritic efficacies through a novel mechanism. We aimed to prospectively examine the effect of nalfurafine hydrochloride on sleep quality for patients with CLD with pruritus utilising actigram. Methods and analysis This study will be a single-centre, prospective, interventional, single-arm study. Our study participants are subjects whose pruritus was confirmed to be uncontrollable by antihistamines or antiallergics within 6 months before informed consent (IC). Evaluation time points using actigram will be (1) before administration of testing drug; (2) after 1 week; (3) after 4 weeks (primary endpoint); and (4) every 4 weeks thereafter. The follow-up period will be 6 months. We will prospectively assess and compare changes in sleep quality in patients with CLD with pruritus undergoing nalfurafine hydrochloride therapy using actigram. Quantitative variables will be compared by paired t-test. Ethics and dissemination This study has received approval from the Institutional Review Board at Hyogo College of Medicine (approval no 2325). The study protocol, IC form and other documents were reviewed and approved. Final data will be publicly disseminated regardless of the results. A report releasing study results will be submitted in an appropriate journal. Trial registration number UMIN000028161; Pre-results.

BAT117213: Ileal bile acid transporter (IBAT) inhibition as a treatment for pruritus in primary biliary cirrhosis: study protocol for a randomised controlled trial. BMC Gastroenterol 2016; 16:71. [PMID: 27431238 PMCID: PMC4950723 DOI: 10.1186/s12876-016-0481-9] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2016] [Accepted: 06/14/2016] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Pruritus (itch) is a symptom commonly experienced by patients with cholestatic liver diseases such as primary biliary cholangitis (PBC, previously referred to as primary biliary cirrhosis). Bile acids (BAs) have been proposed as potential pruritogens in PBC. The ileal bile acid transporter (IBAT) protein expressed in the distal ileum plays a key role in the enterohepatic circulation of BAs. Pharmacological inhibition of IBAT with GSK2330672 may reduce BA levels in the systemic circulation and improve pruritus. METHODS This clinical study (BAT117213 study) is sponsored by GlaxoSmithKline (GSK) with associated exploratory studies supported by the National Institute for Health Research (NIHR). It is a phase 2a, multi-centre, randomised, double bind, placebo controlled, cross-over trial for PBC patients with pruritus. The primary objective is to investigate the safety and tolerability of repeat doses of GSK2330672, and explore whether GSK2330672 administration for 14 days improves pruritus compared with placebo. The key outcomes include improvement in pruritus scores evaluated on a numerical rating scale and other PBC symptoms in an electronic diary completed twice daily by the patients. The secondary outcomes include the evaluation of the effect of GSK2330672 on total serum bile acid (BA) concentrations, serum markers of BA synthesis and steady-state pharmacokinetics of ursodeoxycholic acid (UDCA). DISCUSSION BAT117213 study is the first randomised controlled crossover trial of ileal bile acid transporter inhibitor, a novel class of drug to treat pruritus in PBC. The main strengths of the trial are utility of a novel, study specific, electronic symptom diary as patient reported outcome to measure the treatment response objectively and the crossover design that allows estimating the treatment effect in a smaller number of patients. The outcome of this trial will inform the trial design of future development phase of the IBAT inhibitor drug. The trial will also provide opportunity to conduct metabonomic and gut microbiome studies as explorative and mechanistic research in patients with cholestatic pruritus.

Abstract
Cholestasis results from impairment in the excretion of bile, which may be due to mechanical obstruction of bile flow or impairment of excretion of bile components into the bile canaliculus. When present, cholestasis warrants prompt diagnosis and treatment. The differential diagnosis of cholestasis beyond the neonatal period is broad and includes congenital and acquired etiologies. It is imperative that the clinician differentiates between intrahepatic and extrahepatic origin of cholestasis. Treatment may be supportive or curative and depends on the etiology. Recent literature shows that optimal nutritional and medical support also plays an integral role in the management of pediatric patients with chronic cholestasis. This review will provide a broad overview of the pathophysiology, diagnostic approach, and management of cholestasis beyond the neonatal and infancy periods.
