“…The mean age of our PN subjects was 58.1 years, which is similar to the findings from previous studies (61.5 years; Poland [8], 50.9 years; US [10]). A predominance in females was noted in the Caucasian and African American PN population in the US [11]; however, the sex ratio of our PN patients was male dominant (56.8%), which matches the findings from Boozalis et al [11] in Asians (58.1% male, 41.9% female).…”

“…Based on the current data, the estimated annual prevalence of PN in Korea is 4.82 cases per 1000 dermatology outpatients. Considering that our population is limited to dermatology outpatients, it is understandable that the number is higher than the nationwide annual prevalence of PN reported from Poland (6.52 cases per 100,000 population) [ 8 ], Germany (40 cases per 100,000 population) [ 9 ], and the US (72 cases per 100,000 population) [ 10 ].…”

“…PN was assigned a distinct International Classification of Diseases, 10th Revision (ICD-10) code in 2015 [ 6 , 7 ]. To date, the United States (US), Poland, and Germany have reported nationwide annual prevalence of PN with values of 6.52 (Poland) [ 8 ], 40 (Germany) [ 9 ], and 72 (US) [ 10 ] per 100,000 people. Ethnic differences likely exist, with PN disproportionately affecting African Americans [ 11 ].…”

Prurigo nodularis (PN) is a chronic dermatosis typified by extraordinarily itchy nodules. However, little is known of the nature and extent of PN in Asian people. This study aimed to describe the epidemiology, comorbidities, and prescription pattern of PN in Koreans based on a large dermatology outpatient cohort. Patients with PN were identified from the Catholic Medical Center (CMC) clinical data warehouse. Anonymized data on age, sex, diagnostic codes, prescriptions, visitation dates, and other relevant parameters were collected. Pearson correlation analysis was used to calculate the correlation between PN prevalence and patient age. Conditional logistic regression modeling was adopted to measure the comorbidity risk of PN. A total of 3591 patients with PN were identified at the Catholic Medical Center Health System dermatology outpatient clinic in the period 2007–2020. A comparison of the study patients with age- and sex-matched controls (dermatology outpatients without PN) indicated that PN was associated with various comorbidities including chronic kidney disease (adjusted odds ratio (aOR), 1.48; 95% confidence interval (CI), 1.29–1.70), dyslipidemia (aOR, 1.88; 95% CI, 1.56–2.27), type 2 diabetes mellitus (aOR, 1.37; 95% CI, 1.22–1.54), arterial hypertension (aOR, 1.50; 95% CI, 1.30–1.73), autoimmune thyroiditis (aOR, 2.43; 95% CI, 1.42–4.16), non-Hodgkin’s lymphoma (aOR, 1.95; 95% CI, 1.23–3.07), and atopic dermatitis (aOR, 2.16, 95% CI, 1.91–2.45). Regarding prescription patterns, topical steroids were most favored, followed by topical calcineurin inhibitors; oral antihistamines were the most preferred systemic agent for PN. PN is a relatively rare but significant disease among Korean dermatology outpatients with a high comorbidity burden compared to dermatology outpatients without PN. There is great need for breakthroughs in PN treatment.

“…4,5 To date, there have not been many valid publications on the prevalence of prurigo in a majority of countries. 6,7 In particular, there are no published population-based data on prurigo epidemiology in Germany, except for one report focused on prurigo nodularis. 8 To this end, the current research project aimed to clarify the evidence of prurigo prevalence from claims data with a comprehensive analysis of all prurigo subtypes.…”

Background There are currently no published population-based data on prurigo and pruritus epidemiology in Germany.Objectives We present the prevalence, incidence and comorbidity frequency of prurigo and pruritus in Germany. Methods This was a retrospective healthcare research study based on anonymized routine data from the German health insurance company DAK-Gesundheit. Evaluations were carried out for 2 006 003 adults who were insured as of 31 December 2010. Prurigo and pruritus diagnoses were based on International Classification of Diseases, Tenth Revision, German Modification (ICD-10-GM) codes. ResultsPrevalence was determined to be 0.21% (adjusted for sex and age 0.19%) for prurigo and 2.21% (adjusted 2.14%) for pruritus in 2010. The adjusted rates extrapolated to the total German population in 2010 show that 130 685 adults would have received a prurigo diagnosis and 1 461 024 a diagnosis of pruritus. In 2011, incidence of new prurigo and pruritus cases was 0.13% (adjusted 0.12%, extrapolated 77 263 cases) and 1.51% (adjusted 1.46%, extrapolated 978 885), respectively. Adults with prurigo suffered most frequently from hypertension (35.16%), hyperlipidaemia (24.95%) and depression (21.97%); all were reported more frequently in patients with prurigo compared with the general population (P < 0.001). Similarly, adults with pruritus suffered most frequently from hypertension (31.28%), hyperlipidaemia (23.52%) and depression (18.91%) compared with patients without pruritus (P < 0.001).Conclusions Our data show that prurigo is a relatively rare but significant disease and that pruritus is frequent and very variable in appearance, and both have a high comorbidity burden.

“…HS is totally different from Harlequin colour change, a benign and transient feature that lasts for only several minutes and resolves spontaneously in neonates. 4 The treatment for HS should focus on addressing the underlying cause. Sympathectomy, stellate ganglion blocks and botulinum toxin application 5 have been recommended for patients who experience serious social embarrassment.…”

Fund and associated with those of inpatients who were hospitalized at Rzesz ow for CNPG.In USA, a first study analysed data from Centres for Disease Control and Prevention 5 on the diagnosis of lichenification (ICD-9 code 698.3: both lichen simplex chronicus and CNPG) were analysed, as well as data from Johns Hopkins Health System. The number of outpatient visits per year for CNPG was estimated at 13 (95% CI, 9-18) per 100 000.
