RESUMEN

Nearly half of the deaths among hospitalized human immuno deficiency virus-infected patients in the highly active antiretroviral therapy era have been attributed to liver disease. This may range from an asymptomatic mild increase of liver enzymes to cirrhosis and liver failure. Different works of literature elucidated both retroviral infection and the adverse effects of highly active antiretroviral therapy as a cause of hepatotoxicity. Individual adaptations to medications and environmental exposures, shaped by cultural norms and genetic predispositions, could potentially modulate the risk and progression of liver disease in this population. Therefore, this study aims to assess the predictors of severe hepatotoxicity in retroviral-infected adults receiving highly active antiretroviral therapy regimens within the Ilubabor Zone, Southwest Ethiopia. A facility-based cross-sectional study was conducted among adult retroviral-infected patients in five selected anti-retro virus therapy clinics from May1 to July 30/2022. A systematic sampling technique was used to select 457 study participants and Binary logistic regression statistical data analysis was used, P value < 0.05 was considered statistically significant. The prevalence of severe hepatotoxicity was 21.44% in the study population. CD+4 count < 200 cells/mm3 (AOR = 2.19, 95% CI 1.04-5.22, P = 0.01), human immunodeficiency virus co-infection with tuberculosis (AOR = 2.82, 95% CI 1.01-8.29, P = 0.03) and human immuno deficiency virus co-infection with hepatitis-B/hepatitis C virus (AOR = 5.02, 95% CI 1.82-16.41) were predictors of severe hepatotoxicity. The magnitude of severe hepatotoxicity was high among adult retroviral-infected patients on highly active anti-retroviral drug regimens. Co-infection of human immuno deficiency virus with hepatitis B virus or hepatitis C virus, tuberculosis and CD4+T-cell count below 200 cells/mm3 were predictors of severe hepatotoxicity. Therefore, HIV patients on highly active antiretroviral therapy require close attention and regular monitoring of their liver function.

RESUMEN

Turmeric is widely used worldwide, and there are many examples of its use in treating hepatobiliary diseases. The gut-liver axis is a bidirectional relationship between gut microorganisms and the liver that is closely related to the pathogenesis of hepatobiliary diseases. This review systematically summarizes the components of turmeric. It links the studies on turmeric affecting gut microorganisms to its effects on liver and biliary diseases to explain the potential mechanism of turmeric's regulation of the gut-liver axis. Besides, ethnopharmacology, phytochemicals, and clinical adverse events associated with turmeric have been researched. Furthermore, turmeric is a safe agent with good clinical efficacy and without apparent toxicity at a certain amount. By summarizing the influence of turmeric on the liver by regulating the gut-liver axis, especially the gut microbiota, it provides a preclinical basis for using turmeric as a safe and effective therapeutic agent for the prevention and treatment of hepatobiliary diseases based on the gut-liver axis. However, more efforts should be made to exploit its clinical application further.

RESUMEN

Melatonin (MEL) is produced and secreted by the pineal gland as well as the small intestine, liver, retina, lymphocytes, and melanocytes in the skin in both experimental animals as well as in humans. While pineal and retinas MEL is closely related to the light/dark cycle, the production of MEL by other so called extrapineal tissues is independent of such circadian rhythm. Among the primary mechanisms of action of MEL in humans, the most important are interaction of MEL with specific receptors (M1, M2, M3) and the MEL 'scavenging' activity against the formation of free oxygen metabolites as a result of MEL's ability to transfer free electrons and stimulation of the expression of redox reaction enzymes. In addition, MEL binds to intracellular proteins such as calmodulin, thereby affecting the course of cell cycle, and it has been shown to activate of nuclear receptors belonging to the retinoid orphan receptors/retinoid Z receptors (ROR/RZR) subfamily. MEL exerts regulatory effects on the master clock regulating diurnal rhythms. This updated review presents current view on the synthesis and metabolism of MEL and the growing body of experimental evidence transferable to the practical medicine supporting a pleiotropic molecule beneficial effects on the health including protection against various organ abnormalities, including internal organs such as the liver. Although the beneficial effects of MEL in various types of liver damage have been well documented in experimental studies, there are relatively few studies on liver dysfunction in humans. Considering the worldwide obesity pandemic often associated with the occurrence of steatohepatitis and cirrhosis, the beneficial effects of MEL in liver pathology should be proven in randomized trials involving patients presenting with hepatic disorders.

RESUMEN

Digestive system diseases remain a formidable challenge to human health. NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome is the most characteristic multimeric protein complex and is involved in a wide range of digestive diseases as intracellular innate immune sensors. It has emerged as a research hotspot in recent years. In this context, we provide a comprehensive review of NLRP3 inflammasome priming and activation in the pathogenesis of digestive diseases, including clinical and preclinical studies. Moreover, the scientific evidence of small-molecule chemical drugs, biologics, and phytochemicals, which acts on different steps of the NLRP3 inflammasome, is reviewed. Above all, deep interrogation of the NLRP3 inflammasome is a better insight of the pathomechanism of digestive diseases. We believe that the NLRP3 inflammasome will hold promise as a novel valuable target and research direction for treating digestive disorders.

RESUMEN

This study analyzed and reported the basic information and clinical evidence of Chinese patent medicines for digestive system diseases in children in a scoping review manner. Based on the drug instructions, the basic information of Chinese patent medicines for digestive system diseases in children was obtained by searching the three lists of national medicines. At the same time, the relevant clinical literatures from the first day of establishment to March 7, 2022 were obtained from Chinese and English databases. According to the screening criteria, 39 Chinese patent medicines were included, involving 8 dosage forms. Eight Chinese medicines including Crataegi Fructus, Poria, Citri Reticulatae Pericarpium, Hordei Fructus Germinatus, Arecae Semen, Massa Medicata Fermentata, Dioscoreae Rhizoma, and Atractylodis Macrocephalae Rhizoma were frequently used, and the main effects were invigorating spleen, checking diarrhea, promoting digestion, clearing heat, and harmonizing stomach. The indications for Chinese patent medicines were mainly diarrhea, anorexia, food accumulation, dyspepsia, and rotavirus enteritis in children. Among all drug instructions, only 4 mentioned adverse reactions and 6 mentioned contraindications. Ninety-two clinical studies were included ultimately, including 84 randomized controlled studies, 2 systematic reviews/Meta-analysis, 1 retrospective study, and 5 case series. The literatures only covered 21 kinds of Chinese patent medicines, with the most studies related to Xingpi Yanger Granules, accounting for 32.6% of the total literature volume. The sample size in the literatures was mainly focused on 51-200 cases, and 51-100 cases were selected by the most literatures, accounting for 34.45%. The interventions of the experimental group were mainly Chinese patent medicines or Chinese patent medicines combined with western medicines. The literatures with treatment course of 0-7 d accounted for the largest proportion(51.10%). The effective rate and symptom improvement time were used as the indexes to evaluate the results. The main adverse reactions were vomiting, constipation, nausea, rash, cold, diarrhea, redness of the skin around the umbilicus, or red itchy skin. The analysis of this study found that Chinese patent medicines have good curative effect and research prospects in the treatment of digestive system diseases in children. However, most clinical evidence has problems, such as limited indexes to evaluate the results, lack of traditional Chinese medicine characteristics, uneven quantity and low quality of Chinese patent medicine literatures, and insufficient specification of instructions. In the future, high-quality clinical studies on this field should be actively carried out, and economic studies and clinical comprehensive evaluation of Chinese patent medicines should be strengthened to explore the characteristics and advantages of its treatment, so as to provide decision-making basis for finding the accurate clinical positioning and promoting the rational clinical application of Chinese patent medicines for treating digestive system diseases in children.

RESUMEN

Digestive system diseases arise primarily through the interplay of genetic and environmental influences; there is an urgent need in elucidating the pathogenic mechanisms of these diseases and deploy personalized treatments. Traditional and long-established model systems rarely reproduce either tissue complexity or human physiology faithfully; these shortcomings underscore the need for better models. Organoids represent a promising research model, helping us gain a more profound understanding of the digestive organs; this model can also be used to provide patients with precise and individualized treatment and to build rapid in vitro test models for drug screening or gene/cell therapy, linking basic research with clinical treatment. Over the past few decades, the use of organoids has led to an advanced understanding of the composition of each digestive organ and has facilitated disease modeling, chemotherapy dose prediction, CRISPR-Cas9 genetic intervention, high-throughput drug screening, and identification of SARS-CoV-2 targets, pathogenic infection. However, the existing organoids of the digestive system mainly include the epithelial system. In order to reveal the pathogenic mechanism of digestive diseases, it is necessary to establish a completer and more physiological organoid model. Combining organoids and advanced techniques to test individualized treatments of different formulations is a promising approach that requires further exploration. This review highlights the advancements in the field of organoid technology from the perspectives of disease modeling and personalized therapy.

RESUMEN

BACKGROUND: Hepatobiliary disease currently serves as an urgent health issue in public due to health-modulating factors such as extension of life expectancy, increasingly sedentary lifestyles and over-nutrition. A definite treatment remains lacking owing to different stages of the disease itself and its intricate pathogenesis. Traditional Chinese medicine (TCM) has been gradually popularized in clinic with the satisfactory efficacy and good safety. Curcumae Rhizoma (called E Zhu, EZ in Chinese) is a representative herb, which has been used to treat hepatobiliary disease for thousands of years. PURPOSE: To systematically summarize the recent research advances on the pharmacological activities of EZ and its constituents, explain the underlying mechanisms of preventing and treating hepatobiliary diseases, and assess the shortcomings of existing work. Besides, ethnopharmacology, phytochemicals, and toxicology of EZ have been researched. METHODS: The information about EZ was collected from various sources including classic books about Chinese herbal medicine, and scientific databases including Web of Science, PubMed, ScienceDirect, Springer, ACS, SCOPUS, CNKI, CSTJ, and WANFANG using keywords given below and terms like pharmacological and phytochemical details of this plant. RESULTS: The chemical constituents isolated and identified from EZ, such as terpenoids including ß-elemene, furanodiene, germacrone, etc. and curcuminoids including curcumin, demethoxycurcumin, bisdemethoxycurcumin, etc. prove to have hepatoprotective effect, anti-liver fibrotic effect, anti-fatty liver effect, anti-liver neoplastic effect, and cholagogic effect through TGF-ß1/Smad, JNK1/2-ROS, NF-κB and other anti-inflammatory and antioxidant signaling pathways. Also, EZ is often combined with other Chinese herbs in the treatment of hepatobiliary diseases with good clinical efficacy and no obvious adverse reactions. CONCLUSION: It provides a preclinical basis for the efficacy of EZ as an effective therapeutic agent for the prevention and treatment of hepatobiliary diseases. Even so, the further studies still needed to alleviate hepatotoxicity and expand clinical application.

RESUMEN

Ferroptosis, a newly described type of iron-dependent programmed cell death that is distinct from apoptosis, necroptosis, and other types of cell death, is involved in lipid peroxidation (LP), reactive oxygen species (ROS) production, and mitochondrial dysfunction. Accumulating evidence has highlighted vital roles for ferroptosis in multiple diseases, including acute kidney injury, cancer, hepatic fibrosis, Parkinson's disease, and Alzheimer's disease. Therefore, ferroptosis has become one of the research hotspots for disease treatment and attracted extensive attention in recent years. This review mainly summarizes the relationship between ferroptosis and various diseases classified by the system, including the urinary system, digestive system, respiratory system, nervous system. In addition, the role and molecular mechanism of multiple inhibitors and inducers for ferroptosis are further elucidated. A deeper understanding of the relationship between ferroptosis and multiple diseases may provide new strategies for researching diseases and drug development based on ferroptosis.

RESUMEN

Molecular heterogeneity of hepatobiliary tumor including intertumoral and intratumoral disparity always leads to drug resistance. Here, seven hepatobiliary tumor organoids are generated to explore heterogeneity and evolution via single-cell RNA sequencing. HCC272 with high status of epithelia-mesenchymal transition proves broad-spectrum drug resistance. By examining the expression pattern of cancer stem cells markers (e.g., PROM1, CD44, and EPCAM), it is found that CD44 positive population may render drug resistance in HCC272. UMAP and pseudo-time analysis identify the intratumoral heterogeneity and distinct evolutionary trajectories, of which catenin beta-1 (CTNNB1), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), and nuclear paraspeckle assembly transcript 1 (NEAT1) advantage expression clusters are commonly shared across hepatobiliary organoids. CellphoneDB analysis further implies that metabolism advantage organoids with enrichment of hypoxia signal upregulate NEAT1 expression in CD44 subgroup and mediate drug resistance that relies on Jak-STAT pathway. Moreover, metabolism advantage clusters shared in several organoids have similar characteristic genes (GAPDH, NDRG1 (N-Myc downstream regulated 1), ALDOA, and CA9). The combination of GAPDH and NDRG1 is an independent risk factor and predictor for patient survival. This study delineates heterogeneity of hepatobiliary tumor organoids and proposes that the collaboration of intratumoral heterogenic subpopulations renders malignant phenotypes and drug resistance.

RESUMEN

ETHNOPHARMACOLOGICAL IMPORTANCE: Brazilian medicinal species of the Psidium genus are rich in secondary metabolites such as terpenes and phenolic compounds and present biological activities for several human diseases. For the native Psidium species, there are no specific research reports for any member of the genus about ethnobotanical research, hindering the joint analysis of its therapeutic indications together with the scientific evidence already investigated. STUDY OBJECTIVE: Analyze the therapeutic indications, the main chemical constituents, and the biological activities of native species of the Psidium to Brazil. MATERIALS AND METHODS: Systematic research was carried out in the Scopus, ScienceDirect, PubMed, and Web of Science databases over a period of ten years. Articles in English, Portuguese and Spanish were used. The research was divided into three phases, seeking information on ethnobotany, chemical composition and biological activities. The words were combined to structure the descriptors used in the search. RESULTS: A total of 13 native species belonging to the Psidium genus were identified in this analysis, Psidium acutangulum DC., Psidium brownianum Mart. ex DC., Psidium cattleyanum Sabine, Psidium densicomum Mart. ex DC., Psidium grandifolium Mart. ex DC., Psidium guineense Sw., Psidium laruotteanum Cambess., Psidium myrsinites DC, Psidium myrtoides O. Berg, Psidium salutare (Kunth) O. Berg, Psidium schenckianum Kiaersk., Psidium sobralianum Proença & Landrum, Psidium striatulum Mart. ex DC. Of these, six were indicated in folk medicine, digestive system disorders being their main therapeutic indication. Most species presented an investigation of chemical composition and biological activity. They are rich in phenolic compounds, flavonoids, and terpenes and have antimicrobial, antioxidant, antiproliferative, and repellent activities. CONCLUSIONS: Native species of the Psidium genus are important sources of active ingredients in combating adversities that affect the human health, especially regarding the digestive system. They have a rich chemical composition, responsible for the biological activities demonstrated for the species.

RESUMEN

BACKGROUND/AIMS: Prolonged acid suppression from proton pump inhibitor (PPI) has been shown to cause gut microbiota alteration which may increase risk of various infections in adults. We aimed to characterize gut microbiota profiles in children after a short-term use of PPI. MATERIALS AND METHODS: Children aged 1-18 years who underwent PPI therapy were included during April-December 2017. We excluded children who previously used antibiotics or acid suppressants, had a history of acute gastroenteritis or specific food avoidance one month prior to the enrolment. The stool samples before and after the PPI use were collected for gut microbiota composition. The 16S ribosomal RNA gene sequencing was performed by using Illumina MiSeq. The differences in gut microbiota profile after the use of PPI were compared to pre-PPI period. RESULTS: We completed stool collection in 20 children (median age of 5.8 years and 60% were female). No significant changes in the overall number of species-level taxonomy categories or predominant bacteria phylum (Bacteroidetes) were noted. We found a trend increase in the proportion of phylum Firmicutes among children living in the metropolitan/suburban area (P=.07) and among males (P=.11). In four children with infection-related adverse effects, we noted a non-significant increase in the proportion of phylum Firmicutes after the PPI use (from 35 to 52%, P = .14). CONCLUSION: Even the total number and predominant gut microbiota did not significantly change after a four- to eight-week course of PPI therapy; we found a trend of increased proportion of phylum Firmicutes in certain groups of children.

RESUMEN

An extensive study has been made to identify, document, and investigate the ethnomedicinal plants used by Rakhine ethnic minorities in Patuakhali and Barguna District of southern Bangladesh for the term of April 2018 to June 2019. In this article, we have focused on the Rakhine population trends, management concerns, and some actions for conserving the Rakhine population diversity in the study area. In this study, we have identified the locations where Rakhine population lives in Patuakhali and Barguna districts. A total of 86 plant species belonging to 71 genera and 43 families were reported to be used for treating more than 57 various physical ailments under 14 illness categories from the study area. For each of the species, the botanic name, common name, Rakhine name, family, habit, parts used and traditional medicinal uses of the plant species have been presented. The maximum numbers of ethnomedicinal plant species were utilized to treat gastrointestinal complaints (43) taken after by the treatment of dermatological issues (36). The highly cited (75.60%) plant species were found to be Ananas comosus and Aegle marmelos used for gastro-intestinal (Stomach pain, indigestion, and dysentery) digestive disorders and subsequently followed by Colocasia esculenta (70.73%) used for cut, bleeding and wound healing. The results of this study have shown that Rakhine indigenous communities still depend on conventional plant-based medication to remedy various diseases and therapeutic purposes in the study area. Our findings have also shown that despite there have adequate phytodiversity in the natural habitat of the study area but the number of Rakhine population has been declining significantly day-by-day. As an ultimate result, we have lost the plant-based traditional medicinal knowledge of Rakhine indigenous communities in Bangladesh. As a rich source of traditional knowledge and cultural diversity, it calls for urgent initiatives to conserve the cultural heritage of the Rakhine community as well as the diversity of Rakhine ethnic group.

RESUMEN

Plant species of the Poaceae family are not only used as fodder and forage but also contribute substantially to the treatment of various health disorders, particularly in livestock. Consequently, the present study was aimed to document the therapeutic uses of Poaceae practiced by the inhabitants of the Punjab Province for the treatment of various veterinary health disorders. Semi structured interviews, group discussion and field walks were conducted to collect the data. Quantitative indices including cultural significance index (CSI), relative frequency of citations (RFC), fidelity level (FL), relative popularity level (RPL), and Jaccard Index (JI) were used for the data analysis. Traditional uses of 149 species belonging to 60 genera and 16 tribes of 5 sub families of Poaceae were recorded. Whole plants and leaves were the most consistently used parts with 40.94 and 29.53%. The plants were mainly given orally as fodder (59 reports) without processing followed by decoction (35 reports). Most of the species were employed to treat infectious diseases (25.93%), and digestive disorders (14.10%). Triticum aestivum had the highest CSI, RFC and RPL levels at 8.00, 0.96, 1.00, respectively, followed by Oryza sativa and Poa annua. Likewise, T. aestivum and Saccharum spontaneum had 100% FL and ROP. Jaccard index ranged from 12.25 to 0.37. Twelve plant species namely Chrysopogon zizanioides (anti-inflammatory), Pennisetum lanatum (improve bull fertility), Cymbopogon citratus (glandular secretion), Sorghum saccharatum and Themeda triandra (malaria), Aristida funiculate (anticancer), Koeleria argentia (skin allergies), Tetrapogon villosus (antibacterial), Cynodon radiatus (eyes infection), Sporobolus nervosa (Jaundice), Enneapogon persicus (antifungal), and Panicum repens (dysfunctional cattle organs) were reported for the first time, with novel ethnoveterinary uses. The inhabitants of the study area had a strong association with their surrounding plant diversity and possessed significant knowledge on therapeutic uses of Poaceae to treat various health disorders in animals. Plant species with maximum cultural and medicinal values could be a potential source of novel drugs to cure health disorders in animals and human as well.

RESUMEN

PURPOSE: To describe Australians' prescribed medicine use on a typical day (September 25, 2018). METHODS: We conducted a cross-sectional study using nationally representative dispensing claims data using the Australian Government Department of Human Services random 10% sample of all Australians eligible for prescription medicines subsidised through the Australian Pharmaceutical Benefits Scheme (PBS). Our main outcome measures were the number and proportion of people using at least one prescribed medicine and the specific medicine groups and classes on the day. We estimated the proportion of Australians using these medicines using the mid-year Australian population as the denominator. We quantified multiple medicine use by calculating the number and proportion of people experiencing polypharmacy (the use of 5 or more unique medicines) and hyper-polypharmacy (the use of 10 or more unique medicines). RESULTS: We found that 9.0 million Australians used at least one PBS medicine on September 25, 2018; equating to 27.5 million medicines in use across Australia. "Cardiovascular system", "nervous system" and "alimentary tract and metabolism" medicines comprised the top three medicine groups. Over 1.8 million people experienced polypharmacy on the day, accounting for 13.6 million dispensed medicines. 1 022 590 (45%) people aged ≥70 years old experienced polypharmacy and 188 930 (8%) experienced hyper-polypharmacy. CONCLUSIONS: Rates of polypharmacy were high, particularly in the people most susceptible to polypharmacy-related harm. Strategies to optimise the risk-benefit ratio of medicines and to reduce polypharmacy through "choosing wisely" and "de-prescribing" in this age group are needed. Australia's national data provides a benchmark to inform global medicine utilisation practices.

RESUMEN

The overall objective of these guidelines is to provide evidence-based recommendations for the diagnosis and management of immunoglobulin G4 (IgG4)-related digestive disease in adults and children. IgG4-related digestive disease can be diagnosed only with a comprehensive work-up that includes histology, organ morphology at imaging, serology, search for other organ involvement, and response to glucocorticoid treatment. Indications for treatment are symptomatic patients with obstructive jaundice, abdominal pain, posterior pancreatic pain, and involvement of extra-pancreatic digestive organs, including IgG4-related cholangitis. Treatment with glucocorticoids should be weight-based and initiated at a dose of 0.6-0.8 mg/kg body weight/day orally (typical starting dose 30-40 mg/day prednisone equivalent) for 1 month to induce remission and then be tapered within two additional months. Response to initial treatment should be assessed at week 2-4 with clinical, biochemical and morphological markers. Maintenance treatment with glucocorticoids should be considered in multi-organ disease or history of relapse. If there is no change in disease activity and burden within 3 months, the diagnosis should be reconsidered. If the disease relapsed during the 3 months of treatment, immunosuppressive drugs should be added.

RESUMEN

BACKGROUND: Plants have been used as a primary source of medicine since ancient times and about 80% of the world's population use herbal medicine to treat different ailments. Plant use knowledge differs in space and time and thus requires documentation to avoid its loss from one generation to another. METHODS: In order to accomplish the survey, semi-structured questionnaires were used. The data collected included names of plant species, parts used, ailments treated, growth habit, methods of preparation and mode of administration of the herbal remedies. Descriptive statistics were used to present the data in form of tables and a graph. RESULTS: Results showed that 50 plant species belonging to 26 families were utilized in the treatment of paediatric diseases of which Asteraceae and Lamiaceae were the most common. Leaves (80%) were the most commonly used and decoctions were the main method of preparation. Twenty nine health conditions were treated out of which digestive disorders, malaria and respiratory tract infections were predominant. Herbs and shrubs were equally dominant. CONCLUSION: Herbal remedies are an important source of treatment for paediatric diseases in Buhunga Parish. However, there is need for collaboration between herbal medicine users and scientific institutions to help in the discovery of new drugs based on indigenous knowledge. Scientists ought to explore suitable methods of preparation and dosage formulations in order to achieve the best benefits from herbal remedies.

RESUMEN

An important factor determining the pharmacological response to antitumor drugs is their concentrations in cancer cells, which accounts for the net interaction with their intracellular molecular targets. Accordingly, mechanisms leading to reduced intracellular levels of active agents play a crucial role in cancer chemoresistance. These include impaired drug uptake through solute carrier (SLC) proteins and efficient drug export by ATP-dependent pumps belonging to the ATP-binding cassette (ABC) superfamily of proteins. Since the net movement of drugs in-and-out the cells depends on the overall expression of carrier proteins, defining the so-called transportome, special attention has been devoted to the study of transcriptome regarding these proteins. Nevertheless, genetic variants affecting SLC and ABC genes may markedly affect the bioavailability and, hence, the efficacy of anticancer drugs.

RESUMEN

Chronic pruritus is a symptom of various internal disorders. In contrast to dermatological diseases, pruritus does not present with primary skin alterations in these patients. However, intense scratching my cause secondary skin changes such as abrasion, excoriation, prurigo nodularis, or in rare cases even scarring. The most common internal causes for chronic pruritus are chronic kidney disease, hepatobiliary, and hematological disorders as well as adverse drug reactions. Pruritus is less commonly seen in patients with endocrine or metabolic diseases, malabsorption syndromes, infectious diseases, and solid tumors. The pathogenesis of pruritus in these disorders remains largely elusive, albeit first insights have been gained for uremic and cholestatic pruritus. Antipruritic treatment is therefore symptomatic in most cases and may represent a clinical challenge. The calcium channel blockers gabapentin and pregabalin have the best proven efficacy in chronic kidney disease associated pruritus. In Japan, nalfurafine, a κ-opioid receptor agonist, has been licensed for this indication. UVB light may also attenuate uremic symptoms. In patients suffering from hepatobiliary disorders the sequestrant cholestyramine and the enzyme inducer rifampicin are effective. Furthermore, bezafibrate, the µ­opioid receptor antagonists and, in Japan, nalfurafine may be used to ameliorate cholestatic pruritus. So far, no randomized controlled trials have been performed for chronic itch in other internal disorders. Antipruritic treatment is symptom-based with a focus on the effective therapy of the underlying disease.
