Anal pruritus:Don’t look away

Anal pruritus is a common anorectal symptom that can significantly impair a patient’s quality of life,including their mental health.It can be one of the most difficult proctological conditions to treat.Patients often delay seeking medical attention,since it is an embarrassing but non-life-threatening situation.Pruritus ani can be associated with idiopathic and secondary causes,such as anorectal diseases,cancer(anal or colorectal),dermatological and sexually transmitted diseases,fungal infections and systemic diseases.If patients are referred for a colonoscopy,this can sometimes provide the first opportunity to evaluate the perianal area.Classifications of anal pruritus are based on the abnormalities of the perianal skin,one of the most commonly used being the Washington classi-fication.A proper digital anorectal examination is important,as well as an anoscopy to help to exclude anorectal diseases or suspicious masses.Endoscopists should be aware of the common etiologies,and classification of the perianal area abnormalities should be provided in the colonoscopy report.Information on treatment possibilities and follow-up can also be provided.The treatment normally consists of a triple approach:proper hygiene,elimination of irritants,and skin care and protection.Several topical therapies have been described as possible treatments,including steroids,capsaicin,tacrolimus and methylene blue intradermal injections.

Etiologies and Associated Factors of Generalised Pruritus Sine Materia in the Dermatology-Venerology Department of CHUD-Borgou/Alibori (Benin)

Introduction: The aim was to identify the etiologies of generalised pruritus sine materia and to determine the associated factors in Parakou. Methods: This was a retrospective observational study conducted from January 2011 to June 2022. The patients included were of all ages and both sexes in whom the sine materia nature of the pruritus was noted after clinical examination. These patients had an etiological assessment available or not, complete or partial. For each patient, socio-demographic, socio-cultural, socio-economic and clinical data were collected using a pre-established survey form. They were then processed and analysed using Epi Data 3.1 and SPSS version 21 software respectively. Results: The incidence of generalised pruritus sine materia was 0.89% (73 cases/8214 consultants). The predominant etiologies were aquagenic pruritus (16.4%) and intestinal parasitosis (12.3%). After a bi-variate analysis, two risk factors were identified: frequency of towel change greater than 1 month (OR = 3.02;CI95% = 0.98 - 9.31;P = 0.0486) and use of cold water for bath (OR = 3.28;CI95% = 1.09 - 9.81;P = 0.0274). Conclusion: The etiologies and associated factors of generalised pruritus sine materia found in Parakou are varied but are linked to lifestyle. There is an urgent need to raise public awareness of the need to improve lifestyle in order to reduce the frequency of pruritus sine materia. .

Therapeutic Effect of Integrated Traditional Chinese and Western Medicine on Anal Pruritus After Anorectal Surgery

Objective:To explore the therapeutic effect of integrated traditional Chinese and western medicine on anal pruritus after anorectal surgery.Methods:Ninety-eight patients with anal pruritus after anorectal surgery in our hospital were selected as the research subjects.They were divided into two groups,the control group(50 cases)and the study group(48 cases),according to the treatment plan.The control group was under a simple western medicine treatment plan,while the study group was under an integrated traditional Chinese and western medicine treatment plan.The overall efficacy,severity of anal pruritus,time to eliminate clinical symptoms,and anxiety and depression scores of the two groups of patients under different treatment plans were compared.Results:After two weeks of treatment,the total effective rate of the study group was 95.83%,which was significantly higher than that of the control group(82.00%,P<0.05).After 7 and 14 days of treatment,the anal pruritus scores improved significantly in both the groups,but the study group was superior to the control group,with statistical difference(P<0.01).The time of disappearance of skin itching and skin damage in the study group was shorter than that in the control group.After 14 days of treatment,the anxiety and depression scores of both groups were lower than those after 7 days of treatment;however,there was statistical difference between the two groups(P<0.01).Conclusion:In the clinical treatment of anorectal postoperative diseases,such as anal pruritus,the combination of traditional Chinese and western medicine can significantly improve the symptoms of pruritus,shorten the time of disappearance of clinical symptoms,improve depression and anxiety,and create a positive clinical application value in promoting the rehabilitation of patients and improving their quality of life.

Role of narrow band ultra violet radiation as an add-on therapy in peritoneal dialysis patients with refractory uremic pruritus

AIM To assess the role of narrow band ultraviolet B(UVB) as a treatment option in peritoneal dialysis patients with refractory uremic pruritus.METHODS In this retrospective study, 29 adult patients with end stage renal failure on peritoneal dialysis, and who had refractory uremic pruritus, were given narrow band UVB radiation as an add-on therapy to standard care for a duration of 12 wk. The response to the pruritus was assessed both weekly and at the end of the study period using a visual analogue score(VAS).RESULTS The average VAS score at the end of the study was 3.14 ± 1.59, which was significant compared to the baseline value of 7.75 ± 1.02(P < 0.05). Improvements in symptoms were noted in 19 out of 21(90.4%) patients. However, relapse occurred in six out of the 19 patients who responded. The dropout rate was high during the study period(33.3%).CONCLUSION Narrow band UVB is effective as an add-on therapy in peritoneal dialysis patients with refractory uremic pruritus. However, the present regime is cumbersome and patient compliance is poor.

Study of pruritus in chronic hepatitis C patients

AIM:To investigate the occurrence and severity of pruritus in chronic hepatitis C patients treated with or without interferon(IFN)therapy.METHODS:A total of 89 patients with chronic hepatitis C and 55 control(non-hepatitis)patients were asked to rate their experience of diurnal and nocturnal pruritus in the preceding week using a visual analogue scale(VAS)and a five-point scale,respectively.Blood samples were taken and serum thymus and activationregulated chemokine(TARC)levels were measured by enzyme-linked immunosorbent assay.RESULTS:A significantly greater proportion of chronic hepatitis C patients experienced nocturnal pruritus compared with control(58.4%vs 5.5%,P<0.0001).Chronic hepatitis C patients also had more severe pruritus compared with control patients,indicated by the higher mean VAS scores in both the IFN-treated and non-IFN-treated groups.In particular,patients who received combined peginterferon alfa-2b and ribavirin had significantly higher mean VAS scores than those receiving peginterferon alfa-2a or no IFN treatment.SerumTARC levels did not correlate with pruritus scores,and no significant differences in TARC levels were observed between the IFN-treated and non-IFN-treated groups.CONCLUSION:Patients with chronic hepatitis C experience pruritus more than those without.Serum TARC levels do not correlate with pruritus severity in chronic hepatitis C patients.

Presence of Obstetrics Cholestasis in Mothers Presenting with Pruritus in Pregnancy: In a Low Resource South Asian Setting

Obstetric cholestasis (also referred to as intrahepatic cholestasis of pregnancy—ICP) is a pruritic form of reversible cholestasis that is associated with significant fetal risks. There is a paucity of research regarding pregnancy outcomes of the mothers with obstetric cholestasis in the South Asian setting. Hence, the objective of this study was to determine the prevalence of obstetric cholestasis among mothers presenting with pruritus during pregnancy and to describe the characteristics and outcomes for those diagnosed with ICP in comparison with those with pruritus in the absence of ICP. Methods: All mothers presenting with pruritus to De Soyza Maternity hospital in Colombo Sri Lanka, between 1st January 2011 to 1st January 2014, were recruited for the study. A standard set of biochemical tests were used for diagnosis of ICP. An interviewer administered questionnaire and patient records were used for data collection. Presentation, characteristics and pregnancy outcomes were assessed and compared for mothers with ICP against those with pruritus in the absence of ICP. Results: The prevalence of ICP in the study population was found to be 27% (n = 27). Generalized pruritus with pruritus of the palms and soles was identified as the commonest pattern of pruritus for diagnosed with ICP. Delivery before 37 weeks (p = 0.001), meconium stained liquor (p = 0.004), placental abruption (p = 0.005), postpartum hemorrhage (p = 0.005), bleeding manifestation (p = 0.006), preterm labor (p = 0.031) and fetal distress (p = 0.035) were found to be significantly associated with the presence of ICP. Conclusions: Nearly 1/3 of mothers presenting with pruritus in pregnancy in Sri Lanka are affected by ICP which is associated with an increase in a wide range of adverse maternal and fetal outcomes compared to those with pruritus in the absence of ICP.

Specific Patterns of Spinal Metabolite Ratio Underlying a-Me-5-HTevoked Pruritus Compared with Compound 48/80 Based on Proton Nuclear Magnetic Resonance Spectroscopy

Summary:Mechanisms of pruritus are implicated in the dysregulation of the metabolites in the spinal cord.We investigated pruritus behavioral testing in three groups of young adult male C57B1/6 mice,including one group treated with normal saline,while the other groups intradermally injected with a-Me-5-HT(histamine-independent pruritogen),compound 48/80(histaminedependent pruritogen)at the nape skin of the neck,respectively.Proton nuclear magnetic resonance spectroscopy(MRS)was used to compare spinal metabolites from the vertebral cervical among three groups,and to study the association of spinal metabolite ratio and pruritus intensity.The MRS-measured N-acetylaspartate-to-myoinositol ratio(NAA/Ins)was significantly correlated with the number of scratches between normal saline group and 48/80 group or a-Me-5-HT group(both P<0.0001),indicating that NAA/Ins may be a robust surrogate marker of histamine-independent/dependent pruritogen.There was significant difference in Glu/Ins between normal saline group and 48/80 group(P=0.017),indicating that Glu/Ins may be a surrogate marker of histamine-dependent pruritogen,while GABA/Ins was highly significantly different between normal saline group and a-Me-5-HT group(P=0.008),suggesting that GABA/Ins may be a surrogate marker of histamineindependent pruritogen.MRS may reflect the extent of pruritus intensity elicited by a-Me-5-HT and compound 48/80 with sensitivity similar to the number of scratches,and above potential markers need to be further validated in pre-clinical and clinical treatment trials.

Effects of Silk Fibroin Moisturizing Cream on Acetone/Ether-Induced Dry Skin Pruritus in Mice

Objectives: The morbidity of dry and itchy skin was high during a person’s lifetime and it had a significant negative impact. This study aimed to investigate the positive effect of silk fibroin moisturizing cream on dry skin pruritus induced by acetone/ether-water (AEW) method in mice. Method: We established a dry skin model in mice with AEW treatment, and the control group was treated with ultrapure water. The mice in AEW model group were locally administrated with silk fibroin moisturizing cream (SilkArmor)&reg;. The transepidermal water loss (TEWL), scratching behavior, condition of skin erythema, skin histology (by hematoxylin-eosin staining) and the results of electron microscopy were measured to evaluate the positive effect of SilkArmor on dry and itchy skin in mice. Results: The TEWL value, spontaneous scratching behavior and erythema score were significantly increased after AEW modeling compared with the control group. There was no significant difference in the TEWL value, scratching behavior and erythema score between the SilkArmor group and the control group (P > 0.05). Compared with the AEW group, the value of TEWL, scratching behavior and the erythema score of mice in the AEW + SilkArmor group were improved, with statistically significant differences (P < 0.05). Skin histopathology and electron microscopy also showed that SilkArmor had certain improvement and repairment on AEW-induced skin pathological changes. Conclusions: A dry skin model was successfully established in this experiment, showing that SilkArmor brought an obvious alleviation to AEW-induced dry and itchy skin in mice.

Albumin liver dialysis as pregnancy-saving procedure in cholestatic liver disease and intractable pruritus

Progressive familial intrahepatic cholestasis type 3 (PFIC3) is a rare cholestatic liver disease. Such liver disease can get worse by female hormone disorder. Albumin dialysis or Molecular Adsorbent Recirculating System (MARS) has been reported to reverse severe cholestasis-linked pruritus. Here, we report the first use of MARS during a spontaneous pregnancy and its successful outcome in a patient with PFIC3 and intractable pruritus. Albumin dialysis could be considered as a pregnancy-saving procedure in pregnant women with severe cholestasis and refractory pruritus.

Recent advances in the management of pruritus in chronic liver diseases

Pruritus is a symptom found in patients with chronic liver diseases,especially cholestatic liver diseases such as primary biliary cholangitis.This symptom impairs patient quality of life by disturbing sleep and may lead to consideration of liver transplantation.Mechanisms implicated in pruritus have been associated with the peripheral and central nervous systems,leading to the development of various therapeutic options.Little evidence for the efficacy of most of these treatments is currently available,indicating a need for further investigations.

Hepatitis C virus-associated pruritus: Etiopathogenesis and therapeutic strategies

In addition to its contributing role in the development of chronic liver diseases, chronic hepatitis C virus(HCV) infection is associated with extrahepatic manifestations, particularly, cutaneous-based disorders including those with pruritus as a symptom. Pruritus is frequently associated with the development of chronic liver diseases such as cholestasis and chronic viral infection, and the accumulation of bile acids in patients' sera and tissues as a consequence of liver damage is considered the main cause of pruritus. In addition to their role in dietary lipid absorption, bile acids can trigger the activation of specific receptors, such as the G protein-coupled bile acid receptor(GPBA/ TGR5). These types of receptors are known to play a crucial role in the modulation of the systemic actions of bile acids. TGR5 expression in primary sensory neurons triggers the activation of the transient receptor potential vanilloid 1(TRPV1) leading to the induction of pruritus by an unknown mechanism. Although the pathologic phenomenon of pruritus is common, there is no uniformly effective therapy available. Understanding the mechanisms regulating the occurrence of pruritus together with the conduction of large-scale clinical and evidence-based studies, may help to create a standard treatment protocol. This review focuses on the etiopathogenesis and treatment strategies of pruritus associated with chronic HCV infection.

Alleviating Skin Barrier Disruption,Skin Inflammation,and Pruritus:A Moisturizing Spray Containingβ-Glucan and Panthenol

Objective:Inflammatory skin diseases were proved to be associated with dry skin-induced pruritus.However,the relationship between skin inflammation,skin barrier function,and pruritus remains unclarified.The present study aimed to explore this relationship using an acetone-ether-water(AEW)mouse model,and to investigate the anti-itch effects of the combined application ofβ-glucan and panthenol in a moisturizing spray in this mouse model.Methods:A dry skin-induced chronic pruritus mouse model was established by repeated AEW treatment of the skin.The pruritic behavior,skin barrier function,and expression of molecules related to pruritus and inflammation in topical lesions were measured.The effects of a spray containingβ-glucan and panthenol were observed.Thet test and one-way analysis of variance were used to evaluate differences between groups.Results:AEW treatment triggered spontaneous scratching with significantly increased numbers of scratching bouts,and disrupted the skin barrier with a significant increase in transepidermal water loss values and a significant decrease in filaggrin gene(FLG)expression(allP<0.01).AEW treatment also significantly increased the expression of NOD-like receptor family pyrin domain containing 3,apoptosis-associated speck-like protein containing a CARD,caspase-1,interleukin-1β,and tumor necrosis factor-α,as well as the pruritus-associated molecules nerve growth factor,cathepsin S,and thymic stromal lymphopoietin in the skin(allP<0.01).Application of the spray containingβ-glucan and panthenol significantly alleviated these responses,resulting in a reduced number of scratching bouts in 1 hour,reduced transepidermal water loss values,increased filaggrin mRNA expression,and reduced mRNA levels of NOD-like receptor family pyrin domain containing 3,apoptosis-associated speck-like protein containing a CARD,caspase-1,interleukin-1β,tumor necrosis factor-α,cathepsin S,thymic stromal lymphopoietin,and nerve growth factor in skin lesions(allP<0.05).Conclusion:The present results suggest a relationship between damaged skin barrier function,pruritus,and inflammation.Addingβ-glucan and panthenol to moisturizing skincare products may alleviate pruritus induced by dry skin,improve the damaged skin barrier function,and reduce the inflammatory state in local skin areas.

胆汁淤积性肝病瘙痒的中西医研究进展

Pruritus is common in cholestatic liver disease,with a high clinical incidence rate and complex pathogenesis.Accumulation of potential pruritus inducers such as steroids,bile acids,and lysophosphatidic acid in the systemic circulation is the main cause of pruritus in cholestatic liver disease.Currently,clinical treatment of cholestatic liver disease-related pruritus mainly includes medication,intervention therapy,and some experimental methods.However,there are still problems,such as unclear pathological mechanisms and unsatisfactory treatment responses in some patients with cholestatic liver disease-related pruritus.Effective treatment for patients still faces challenges.By extensively screening patients’plasma(and/or bile)samples through clinical trials,potential pruritus inducers can be identified comprehensively,which can provide a deeper understanding of the itch signaling pathways in cholestatic liver disease and a basis for the development of treatment strategies.Traditional Chinese medicine(TCM)has shown certain characteristics and advantages in clinical treatment.Based on the etiology and pathogenesis,external application,internal administration,and TCM-specific therapies have achieved good clinical efficacy.Similarly,the combination of Chinese medicine and Western medicine has also achieved more effective treatment for patients with cholestatic liver disease-related pruritus.This article will introduce the latest progress in the study of pruritus inducers in cholestatic liver disease and its treatment in TCM and Western medicine.
