Pruritus is common in patients with CTCL and is severe and intractable in the subtypes Sézary syndrome (SS) and folliculotropic mycosis fungoides (MF). Materials and methods: We conducted a systematic review on interventions demonstrating efficacy in reducing pruritus in patients with CTCL. The primary aim of our study was to identify disease-directed and itch-directed therapies effective in reducing CTCL-associated pruritus. Our secondary aim was to outline various tools used to quantify itch in clinical studies. Results: Our study identified multiple disease-directed therapies effective in reducing CTCL-associated pruritus. Most evidence supported the use of histone deacetylase inhibitors. For the agents romidepsin, vorinostat, and quisinostat, reduction in pruritus was achieved in both disease responders and nonresponders. Various therapies were effective in managing pruritus associated with SS and folliculotropic MF. Vorinostat is effective in reducing pruritus in patients with SS. Extracorporeal photophoresis, total skin electron beam therapy, and romidepsin are effective in reducing pruritus in patients with folliculotropic MF. The antiemetic aprepitant is an effective targeted treatment of CTCL-associated pruritus. Aprepitant demonstrated efficacy in reducing pruritus in patients with all stages of MF, including patients with SS. Lignocaine administered via continuous subcutaneous infusion is effective in reducing pruritus in patients with advanced-stage MF, including patients with SS. The most frequently used tools to quantify itch were the Visual Analogue Scale and Numerical Rating Scale. Definitions of a significant reduction in pruritus were extremely varied between studies. Discussion: To our knowledge, this is the first systematic review specifically addressing the management of itch in patients with CTCL. Patients with all stages of CTCL were represented across included studies, including patients with folliculotropic MF and SS. A wide range of treatment options were identified, including options appropriate for patients with end-stage disease.","PeriodicalId":73523,"journal":{"name":"Itch (Philadelphia, Pa.)","volume":"6 1","pages":"e55 - e55"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42853220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Oral antihistamines are commonly used to manage itch in AD, but evidence of its efficacy is lacking and debatable. Methods: A retrospective cohort study on patients with AD treated with antihistamines was conducted at the National Skin Centre from January 2015 to December 2018. Severity of disease was measured using the SCORing Atopic Dermatitis (SCORAD) index. Data was analyzed using a mixed-effects linear model to account for repeated measures on the same individual. Results: There were 161 unique patients with 380 treatment outcomes included in our analysis. Patients who were treated with antihistamines had higher baseline itch and sleep disturbance scores compared with those who were not. We found that the use of antihistamines resulted in significant improvement in itch and sleep disturbance scores with respective mean decreases of 0.67 [95% confidence interval (CI): 0.07, 1.27; P=0.03] and 0.87 (95% CI: 0.22, 1.52; P=0.01) compared with patients not treated with antihistamines. Specifically, second-generation antihistamines improved itch and sleep disturbance scores better than first-generation antihistamines, with a decrease of 0.65 (95% CI: −0.59, 1.88) and 0.61 (95% CI: −0.66, 1.88), respectively, although the difference in effect was not significant. Meanwhile, antihistamine use did not significantly improve total SCORAD and objective SCORAD scores. Conclusion: Treatment with second-generation antihistamines, may be an appropriate treatment modality for managing itch and sleep disturbance in patients with AD.","PeriodicalId":73523,"journal":{"name":"Itch (Philadelphia, Pa.)","volume":"6 1","pages":"e47 - e47"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42233897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As itch is less studied in PD, and pain and itch partially share sensory pathways, we designed this study to identify the occurrence and pattern of spontaneous itch, and responsiveness to a surrogate itch model in PD. Methods: The study protocol was approved (N-20180079) and PD patients and their best matched controls were recruited. A questionnaire was used to collect general information on itch. Sensory alterations were determined by subjective ratings and mechanical sensitivity threshold before and after a standard histamine-dependent itch model on forearms. Itch and pain intensities were rated on visual and numerical rating scales, respectively. Dispersion of itch was drawn on arm charts. Presence and area of alloknesis and hyperknesis were determined. Group comparisons were performed in SPSS with a significant level of 0.05. Descriptive statistic was used for questionnaire’s analysis. Results: Patients (n=20; 68.10±7.91 y, F/M ratio: 8/12) and controls (n=20; 67.35±7.65 y, F/M ratio: 8/12) were examined. PD patients rated less physical and emotional descriptors, except for the stinging (P=0.028). No difference was found between the groups in histamine-provoked itch intensity (P=0.799) or the itchy area. A significantly larger area of hyperknesis was found in PD (P=0.011), but not for the area of alloknesis (P=0.221). Sex-related responses yielded only a tendency toward higher responses in female patients. Discussion: PD does not seem to influence perception of itch, neither spontaneous nor evoked itch, except for hyperknesis area, which was found significantly larger in PD patients following the application of histamine. This finding proposes a potential alteration in central processing of itch that needs further investigation and whether and how it is affected by, for example, PD pathogenesis.","PeriodicalId":73523,"journal":{"name":"Itch (Philadelphia, Pa.)","volume":"6 1","pages":"e49 - e49"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45541501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pruritus is one of the most distressing symptoms, associated with other cutaneous sensory disorders, including paresthesia and cold dysesthesia. No specific treatment exists. CTXs are known to primarily activate voltage-gated sodium channels, but the downstream molecular events that lead to sensory disturbances remain poorly defined. Peptidergic sensory neurons were recently identified as major players in CFP sensory disturbances. Methods: In this study, we examined the role of molecular actors in 2 effects induced by Pacific CTX-2 (P-CTX-2): the increase in cytosolic calcium levels in rat primary sensory neurons; and the release of the neuropeptide substance P (SP) in sensory neurons co-cultured with keratinocytes. Results: Our results (i) rule out the involvement of the Na+/Ca2+ exchanger (NCX) and the transient receptor potential channels transient receptor potential ankyrin 1 and and transient receptor potential vanilloid 1; (ii) show that N-type voltage-gated calcium (Cav) channels contribute to the initiation of the calcium signal elicited by P-CTX-2 in rat sensory neurons, while N-type and L-type Cav channels play equal parts in the SP release in the co-culture; and (iii) identify store-operated calcium entry supported by Orai calcium release-activated calcium modulator 1 (ORAI1) as a critical effector of the late phase of the calcium signal and the subsequent SP release elicited by P-CTX-2.

A detailed medical history together with laboratory and radiological examinations are advised in order to determine the severity of CPG, identify the underlying origin of the itch and assist in the elaboration of a treatment plan. Therapeutically, it is advised to adopt a multimodal approach, including general strategies to control itch, treatment of the underlying pruritic conditions, and of the pruriginous lesions. Topical (corticosteroids, calcineurin inhibitors, capsaicin) and systemic antipruritic agents (eg, gabapentinoids, immunosuppressants, and opioid modulators) as well as physical treatment modalities (phototherapy, cryotherapy) should be employed in a step-wise approach.

We sought to compare the disease-related and itch-related QoL impact between AIBD including pemphigus, bullous pemphigoid (BP), and mucous membrane pemphigoid (MMP). Methods: We performed a retrospective cohort study of patients attending a specialty Autoimmune Blistering Disease Clinic at a single academic center between July 2017 and April 2019. Patients with an established histopathologic or serological diagnosis of pemphigus, BP or MMP with mucosal and/or cutaneous lesions on clinical examination, or patient-reported QoL impact in the past week were recruited to participate. Patients completed Autoimmune Blistering Disease Quality of Life (ABQoL), Treatment of Autoimmune Blistering Disease Quality of Life (TABQoL), and ItchyQoL survey instruments, and disease severity was assessed using the Pemphigus Disease Area Index (PDAI) (pemphigus), Bullous Pemphigoid Disease Area Index (BPDAI) (BP), and Mucous Membrane Pemphigoid Disease Area Index (MMPDAI) (MMP). Statistical analyses were performed using IBM SPSS 26. Results: BP and pemphigus demonstrated similar itch-related QoL impact, greater than that of MMP. Disease severity was significantly associated with itch-related QoL in BP and pemphigus, as was use of biological/targeted therapies in BP alone. Discussion: Itch is a significant symptom in both BP and pemphigus and can negatively affect QoL. Disease severity and treatment type play a role in itch-related QoL in pemphigus and BP.
