Abstract
OBJECTIVE Uremic pruritus is a distressing complication of chronic kidney disease (CKD), associated with mortality, and negatively impacts quality of life. The 5D-Itch Scale (5D-IS) is an easy-to-apply technique that evaluates 5 different dimensions of itching such as duration, severity, course, disability, and prevalence. We aimed to investigate the prevalence of itching in different CKD stages using the 5D-IS and to investigate the factors associated with itching in CKD patients. MATERIALS AND METHODS 5D-IS was used to evaluate itching in chronic hemodialysis (HD) and Stage 3-5 CKD patients. Total itching score and sub-scores consist of duration, severity, course, disability and distribution were obtained. Itching scores and prevalence according to CKD stages were investigated. Also the relationships between itching scores and some laboratory and clinical parameters such as iPTH, Ca, P, CRP levels were examined. RESULTS 158 CKD patients included in the study included (110 Stage 3-5 and 48 HD). The frequency of itching was higher in HD patients than in predialysis patients (62.5% vs 46.4%; p = 0.04). The total itching score increased along with CKD stages 3 to 5 (7.75 ± 3.39, 7.82 ± 4.11 and 9.08 ± 5.12 respectively; p = 0.14). The severity, duration and course scores of itching were similar between the groups, but the distribution scores increased as the CKD stage increased. The laboratory and clinical characteristics of patients with and without itching were not different. Even if a significant positive correlation was detected between the parathyroid hormone levels and both the total 5D-IS scores and all of the sub-scores, Ca and P values were not correlated with itching scores. In the multiple regression analysis, the only parameter that had an effect on the total 5D-IS Score was the parathyroid hormone level. CONCLUSION In CKD, itching affects 40-70% of patients from the early stages. As the CKD stage increases, itching spreads throughout the body. The only parameter that seems to be associated with itching is the PTH level.

Abstract
Objective Uremic pruritus (UP) is a prevalent and troublesome condition affecting individuals with end-stage renal failure, which results in intense pruritus, depression, as well as poor quality of sleep, significantly impacting their quality of life. According to previous studies, acupuncture and acupoint stimulation have been shown to provide additional benefits in treating UP in dialysis patients. In addition, using acupoints combination may yield superior effectiveness compared to utilizing a singular acupoint. To investigate the potential correlations between acupoint combinations, an association-rule analysis was employed. Materials and Methods Apriori algorithms stand out as highly potent techniques for identifying associations in databases; this study utilized an association rule mining to examine the association rules of key acupoint groupings that could be employed for treating UP. Results The analysis utilized information derived from the meta-analysis encompassing 40 randomized controlled trials that used acupuncture to treat UP. In total, 64 acupoints were analyzed, and 71 association rules were found. The following acupoint combinations: Auricular shenmen (TF4), Quchi (LI11), and Geshu (BL17); Auricular heart (Extra14), Sanyinjiao (SP6), and Auricular lung (CO14); and Auricular heart (Extra14), Xuehai (SP10), and Auricular lung (CO14) showed the strongest associations. Conclusion Acupoints involving Auricular shenmen (TF4), Quchi (LI11), Geshu (BL17), Auricular heart (Extra14), Sanyinjiao (SP6), Auricular lung (CO14), and Xuehai (SP10) can be regarded as the core combination of acupuncture points for managing UP.

Abstract
BACKGROUND Chronic kidney disease-associated pruritus (CKD-aP) is an underrated symptom in patients with impaired kidney function. The present study assessed the prevalence, impact on quality of life (QoL) and risk factors for CKD-aP in a contemporary national cohort of patients on haemodialysis. In addition, we evaluated attending physicians' awareness and approach to therapy. METHODS Validated patient's and physician's questionnaires on pruritus severity and QoL were used in combination with information obtained by the Austrian Dialysis and Transplant Registry. RESULTS The prevalence of mild, moderate and severe pruritus in 962 observed patients was 34.4%, 11.4% and 4.3%. Physicians' estimated prevalence values were 25.0 (95% CI 16.8-33.2), 14.4 (11.3-17.6) and 6.3% (4.9-8.3), respectively. The estimated national prevalence estimate extrapolated from the observed patients was 45.0% (95% CI 39.5-51.2) for any, 13.9% (95% CI 10.6-17.2) for moderate and 4.2% (95% CI 2.1-6.2) for severe CKD-aP. CKD-aP severity was significantly associated with impaired QoL. Risk factors for moderate-severe pruritus were higher C-reactive protein [odds ratio (OR) 1.61 (95% CI 1.07-2.43)] and parathyroid hormone (PTH) values [OR 1.50 (95% CI 1.00-2.27)]. Therapy for CKD-aP included changes in the dialysis regimen, topical treatments, antihistamines, gabapentin and pregabalin and phototherapy in a majority of centres. CONCLUSIONS While the overall prevalence of CKD-aP in our study is similar to that in previously published literature, the prevalence of moderate-severe pruritus is lower. CKD-aP was associated with reduced QoL and elevated markers of inflammation and PTH. The high awareness of CKD-aP in Austrian nephrologists may explain the lower prevalence of more severe pruritus.

Abstract
Chronic kidney disease-associated pruritus (CKD-aP) or uremic pruritus (UP) is a frequent symptom in patients with kidney failure receiving kidney replacement therapy. Severe chronic kidney disease-associated pruritus correlates with poor outcome in patients on dialysis. It is multifactorial in etiology and has a significant impact on quality of life. There is, however, limited data for children. This review summarizes current epidemiology, clinical characteristics, pruritus scoring systems, and available therapeutic options for pruritus in patients with chronic kidney disease and those receiving dialysis. Optimal care requires proper awareness of the severity of symptoms, the impact on quality of life, and the possible long-term outcomes. Optimizing dialysis prescription and correcting electrolyte abnormalities are important treatment targets. A wide range of therapeutic options is also available although none are well-studied in children. An earlier recognition of this debilitating symptom in children and treatment is imperative. A higher resolution version of the Graphical abstract is available as Supplementary information.

Abstract
BACKGROUND Uremic pruritus has an impact on the quality of life and sleep of hemodialysis patients, but the majority of cases go unreported and untreated unless severe, due to a lack of awareness. The purpose of this study is to determine the prevalence, associated factors, and impact on health-related quality of life (HR-QOL) and sleep in hemodialysis patients. METHODOLOGY A single-center observational study of 3 months wherein 120 adults on maintenance hemodialysis were included. Baseline characteristics, dialysis-related factors, and lab parameters influencing uremic pruritus were recorded. Those with uremic pruritus completed "12-item pruritus severity scale (12-PSS)", "SKINDEX10", and "Itch-MOS" questionnaires to evaluate severity, impact on HR-QOL, and sleep respectively. RESULTS Sixty seven over one hundred twenty (55.83%) patients had pruritus and majority were mild (40.83%) as per 12-PSS. Those with pruritus (n=67) had a mean age of 56.5±11.3 years, most were males (82%), chronic glomerulonephritis (29.1%) was the commonest cause of end-stage kidney disease, 3 active smokers, and 4 seropositive. 65(97%) patients were on twice-weekly dialysis, 36/67 had <5 years' dialysis vintage and acceptable adequacy. There was no significant association between uremic pruritus and dialysis-related/laboratory parameters. Patients with uremic pruritus demonstrated significantly worse "HR-QOL" (p<0.001) on the "SKINDEX-10", and patients' "Itch-MOS" scores demonstrated a significant decline in sleep quality with increasing pruritus severity (p<0.001). CONCLUSION The majority of patients on maintenance hemodialysis experience uremic pruritus. None of the clinical characteristics, dialysis-related factors, and laboratory parameters affected uremic pruritus. Uremic pruritus patients had the worst HR-QOL & their sleep quality significantly declined as pruritus severity escalated. TRIAL REGISTRATION NUMBER AND DATE OF REGISTRATION Study approval was obtained from Institutional Research Committee and Institutional Ethical Committee (IEC 642/2021). Clinical Trial Registry of India (CTRI) registration (CTRI/2022/01/039143) was also obtained.

Abstract
INTRODUCTION Uremic pruritus (UP) is a common and distressing symptom in end stage renal disease (ESRD) patients. Many approaches have been tested to improve UP without a clear success. We aimed to assess the effect of sertraline on UP in hemodialysis (HD) patients. METHODS This research is a double-blinded, placebo-controlled, multicentric randomized clinical trial which included sixty patients maintained on regular HD. Patients were allocated to receive sertraline 50 mg twice daily or placebo for 8 weeks. The Visual analogue scale (VAS) and the 5-D itch scale were used to assess pruritus before and after the course of treatment. RESULTS At study end in sertraline group, there was a significant decrease from baseline findings in the VAS score (p < 0.001), and the 5-D itch scale (p < 0.001). On the other hand, in placebo group the VAS score showed a slight non-significant decrease (p = 0.469), and the 5-D scale (p = 0.584) increased from baseline measurements. The percentage of patients with severe and very severe pruritus decreased significantly in the sertraline group in both scores [(VAS score: p = 0.004), (5-D itch score: p = 0.002)] with no significant change in the placebo group [(VAS score: p = 0.739), (5-D itch scale: p = 0.763)]. There was a significant positive relation between the VAS and 5-D itch scores and serum urea with p value of 0.002 and 0.001 respectively, and serum ferritin with p value of < 0.001 with both. CONCLUSIONS Patients treated with sertraline had a significant improvement in pruritus as compared with those who received placebo suggesting a potential role for sertraline to treat uremic pruritus in HD patients. Larger randomized clinical trials are needed to confirm these findings. TRIAL REGISTRATION ClinicalTrials.gov NCT05341843. First registration date: 22/04/2022.

Abstract
BACKGROUND Uremic pruritus causes sleep disturbances, poor quality of life, and increased morbidity in patients with chronic kidney disease. Acupuncture has been shown to improve uremic pruritus. There is limited evidence of the efficacy of traditional Chinese therapies. We conducted a systematic review and meta-analysis to evaluate the efficacy of acupoint stimulation therapy in patients with uremic pruritus. METHODS A systematic search of seven databases (up to Sep 2022) was conducted for randomized controlled trials that evaluated the clinical efficacy of acupuncture, acupressure, auricular acupressure, acupoint injection, acupoint thermal therapy, acupoint sticking therapy, or transcutaneous electrical acupoint stimulation in the treatment of patients with uremic pruritus. Two reviewers selected eligible articles for inclusion in the meta-analysis and evaluated the risk of bias via Cochrane Collaboration. The results of pruritus assessments and uremic pruritus-related laboratory parameters were analyzed. RESULTS Forty trials published between 2002 and 2022, including a total of 2,735 participants, were identified for inclusion in the meta-analysis. The effective rates for acupuncture, auricular acupressure, and the combination of acupoint injection and acupoint massage were significantly greater in patients with uremic pruritus compared to the control group. The levels of serum BUN, PTH, and histamine levels were significantly lower vs. control group. CONCLUSIONS Acupuncture, auricular acupressure, and the combination of acupoint injection and acupoint massage seem to be effective in improving uremic pruritus in patients with chronic kidney disease. However, further investigation of these potential treatments is now warranted in larger patient populations and over a longer time frame.

Abstract
Uremic pruritus is a disturbing and refractory symptom in patients with advanced chronic kidney disease. Chinese herbal medicine has been reported to alleviate uremic pruritus. To investigate the effects of Chinese herbal medicine, we conducted a systematic review and meta-analysis on patients with uremic pruritus. We searched databases (prior to 3 May 2022) for randomized controlled trials on the effects of Chinese herbal medicine in treating uremic pruritus. Our meta-analysis included 3311 patients from 50 randomized controlled trials. In patients with uremic pruritus, adjunctive Chinese herbal medicine significantly improved overall effectiveness (risk ratio 1.29, 95% CI 1.23 to 1.35), quality of life, renal function, reduced pruritus score, and inflammatory biomarkers compared to control groups with hemodialysis alone or with anti-pruritic treatments. Chinese herbal medicine treatment showed a time-dependent tendency in improving the visual analog scale of dialysis patients. Compared to control groups, no significantly higher risk of adverse events in patients taking Chinese herbal medicine (risk ratio 0.60, 95% CI 0.22 to 1.63). Chinese herbal medicine appears to be effective and safe in complementing the treatment of patients with uremic pruritus.

Pruritus in Chronic Kidney Disease: An Update. ALLERGIES 2022. [DOI: 10.3390/allergies2030009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/16/2022] Open
Abstract
Chronic kidney disease-associated pruritus (CKDaP) is an often under-diagnosed and under-recognized condition, despite its considerable prevalence within the chronic kidney disease (CKD) population. Universally accepted guidelines are also lacking. The true prevalence of CKDaP worldwide therefore remains unknown, although its negative impact on mortality and health-related quality of life outcomes is very clear. The pathophysiological mechanisms leading to the onset of CKDaP are only partly understood. CKDaP is currently believed to be caused by a multifactorial process, from local skin changes, metabolic alterations, the development of neuropathy and dysregulation of opioid pathways, and psychological factors. Much work has been carried out towards a more systematic and structured approach to clinical diagnosis. Various tools are now available to assess the severity of CKDaP. Many of these tools require greater validation before they can be incorporated into the guidelines and into routine clinical practice. Further efforts are also needed in order to increase the awareness of clinicians and patients so that they can identify the CKDaP signs and symptoms in a timely manner. Currently established treatment options for CKDaP focus on the prevention of xerosis via topical emollients, the optimization of dialysis management, early referral to kidney transplantation if appropriate, oral antihistamine, and a variety of neuropathic agents. Other novel treatment options include the following: topical analgesics, topical tacrolimus, cannabinoid-containing compounds, antidepressants, oral leukotrienes, opioids, and non-pharmacological alternative therapies (i.e., phototherapy, dietary supplements, acupuncture/acupressure). We provide an updated review on the evidence relating to the epidemiology, the pathophysiology, the clinical assessment and diagnosis, and the management of CKDaP.

Lettuce as an Effective Remedy in Uremic Pruritus: Review of the Literature Supplemented by an In Silico Study. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:4231854.

Abstract
Uremic pruritus is a frequent and prominent symptom in patients with advanced or end-stage renal disease. Lack of an effective treatment for kidney disease-associated pruritus often leads to many problems for these patients and makes it difficult to choose an appropriate treatment. The purpose of this evidence-based hypothesis is to share the scientific reasons and related mechanisms in order to claim that lettuce could be useful in the treatment of uremic pruritus. This hypothesis is based on studies related to lettuce and its anti-inflammatory, antioxidant, antidiabetic, sedative, hypnotic, nephroprotective, potassium balancing, and blood purification properties. As a result, we suggest that lettuce could be a good choice for improving and reducing uremic pruritus due to its certain characteristics. Although proof of this hypothesis requires further clinical trial studies, this hypothesis can nevertheless lead to formulating an appropriate therapy for uremic-induced pruritus. By conducting a molecular docking study, we investigated the interactions between nineteen natural bioactive components of lettuce (Lactuca sativa L.) and human kappa opioid receptors. The in silico docking studies revealed that most of the ligands showed better antipruritic efficacy than gabapentin. Gamma-tocopherol, delta-tocopherol, and campesterol demonstrated the highest binding affinities toward the target protein.

Abstract
Chronic kidney disease–associated pruritus (CKD-aP) is a common, yet underrecognized condition in patients with CKD and end-stage kidney disease (ESKD). Real-world observational studies indicate that CKD-aP affects up to 80% of ESKD patients undergoing haemodialysis (HD), with ∼40% experiencing moderate to severe itch. CKD-aP can negatively impact patients’ mental and physical health-related quality of life (HRQoL) and is also associated with sleep disturbance and depression. Several studies have found that CKD-aP is a predictor of adverse medical outcomes, including an increased risk of hospitalizations and mortality. In this article we review the literature relating to the epidemiology of CKD-aP to describe its prevalence across the treatment spectrum of CKD (non-dialysis, HD, peritoneal dialysis and transplant recipients) and to summarize potential risk factors associated with its development. We also review key data from studies that have evaluated the impact of CKD-aP on HRQoL and medical outcomes.

The clinical effectiveness and safety of traditional Chinese medicine uremic clearance granule combined with high-flux hemodialysis in the treatment of uremic pruritus: A protocol for systematic review and meta analysis. Medicine (Baltimore) 2021; 100:e26423. [PMID: 34160430 PMCID: PMC8238327 DOI: 10.1097/md.0000000000026423] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/15/2021] [Accepted: 06/03/2021] [Indexed: 01/04/2023] Open
Abstract
BACKGROUND Skin pruritus is a common complication in patients with uremia. When the hemodialysis time of patients is extended, and the probability of skin pruritus is greater. Patients often have the symptoms of skin pruritus intolerable, affecting the normal sleep and normal life of patients. The patients with uremic pruritus often constant scratching and pruritus skin, resulting in broken skin, and further symptoms such as infection, and subsequent skin shedding, prurigo nodularis, and other adverse complications, aggravating the patient's condition. Some patients will experience symptoms such as depression and insomnia due to skin pruritus, and simply scratching the skin lead to infection. Severely affected patients may even show suicidal tendency, endangering the physical and mental health of patients, and it is needed to give the effective treatment to patients. Hemodialysis is a common treatment for uremic pruritus, which can effectively relieve the pruritus symptoms of patients. The drugs can also relieve the symptoms and improve the degree of pruritus in patients. And some studies show that traditional Chinese medicine UCG combined with HFH in the treatment of uremic pruritus has a very good effect, Therefore, this study will systematically evaluate the clinical efficacy and safety of UCG combined with HFH and HFH alone in the treatment of uremic pruritus. METHODS Use computer to search English and Chinese databases, English databases include: PubMed, Web of Science, EMbase, The Cochrane Library. Chinese databases include: CNKI, CBM, WanFang Data and VIP databases, collecting the RCT on the clinical effectiveness and safety of UCG combined with HFH and HFH alone in the treatment of uremic pruritus. The retrieval time is from the beginning of each database to May 1, 2021. In order to improve the retrieval rate of the literature, the references cited in the included research are also collected and screened. Set Chinese and English as the search language. Two members of the research group independently collected, included and excluded the literatures. In case of disagreement, consulting the third party to assist in the judgment. For the literature with missing data, the original author should be contacted as far as possible to obtain complete data. Two evaluators evaluate the bias risk of included studies according to the Cochrane Handbook bias risk assessment tool for RCT. RevMan 5.3 software is used for statistical analysis and the forest plot is drawn to show the outcome indicators and funnel plot is drawn to show the publication bias. RESULTS This study evaluates the advantages and disadvantages of traditional Chinese medicine UCG combined with HFH and HFH alone in the treatment of uremic pruritus through the clinical effectiveness and safety-related indicators. CONCLUSION This study will give a positive conclusion on the efficacy and safety of uremic clearance granule in the treatment of uremic pruritus, and the research results will be published in professional journals in the form of academic papers, thus benefiting more patients. ETHICS AND DISSEMINATION This study belongs to meta-analysis and all data comes from academic papers published publicly in formal academic journals, so there are no ethical issues involved in this study and no ethical review or approval is required.
