Effectiveness of autologous whole-blood injections in patients with refractory chronic spontaneous urticaria

Background: Nonsedating antihistamines are the treatment of choice for chronic spontaneous urticaria (CSU), while omalizumab and immunosuppressants have also been approved as an add-on treatment. Autologous whole-blood injection (AWBI) has been used in previous studies with ambiguous results. The aim of our study was to evaluate changes in the Urticaria Activity Score (UAS7), Dermatology Life Quality Index (DLQI), and Chronic Urticaria Quality of Life (CU-Q2oL) score, and also the association of serologic markers with disease severity measures after AWBI. Methods: In this observational study, AWBIs were performed (8 courses on a weekly basis) in adults with refractory CSU, who refused an add-on treatment with either omalizumab or immunosuppressants. UAS7, DLQI, and CU-Q2 oL questionnaires and serum concentrations of total IgE, C-reactive protein (CRP), and D-dimer were evaluated before and after the intervention. Results: Nineteen patients (12 females; mean age 54 ± 20.8 years) completed the protocol. Following AWBI, significant improvements in the UAS7 (34.26 ± 8.04 vs. 12.52 ± 10.83, p < 0.001), DLQI (11.63 ± 5.51 vs. 3.47 ± 2.85, p < 0.001), and CU-Q2oL score (32.97 ± 18.71 vs. 10.94 ± 7.71, p < 0.001) were recorded. A negative correlation between the baseline D-dimer levels and UAS7 and DLQI variations (p = 0.002 and p = 0.001, respectively) was noted. D-dimer levels ≥292 ng/mL have been associated with poor responsiveness (sensitivity 75%; specificity 83.3%). No correlation with either total immunoglobulin E or CRP levels was observed. Conclusion: AWBI appears to be a safe, alternative, add-on therapeutic option in refractory CSU, particularly in patients with low plasma levels of D-dimer. © 2017 S. Karger AG, Basel

Psychiatric factors in patients with sensitive skin

The term sensitive skin has been used to describe a clinical phenomenon of skin hyperreactivity induced after exposure to different external factors. The diagnosis is mainly based on patient's self-assessment because of the lack of objective clinical signs of the disease. The aim of this study was to investigate psychiatric factors in patients with sensitive skin and to estimate the possible need for psychological intervention to these patients. Thirty-seven patients with sensitive skin and 38 individuals with nonsensitive skin were studied. The psychometric instruments used were the Symptom Checklist-90 (SCL-90) and the Delusions-Symptoms-States Inventory/states of Anxiety and Depression (DSSI/sAD). Statistically significant differences in subjects with sensitive skin compared to those with nonsensitive skin were observed in the SCL-90 subscales of somatization, phobic anxiety, hostility, interpersonal sensitivity and the DSSI/sAD subscale of anxiety Our findings suggest that somatization, anxiety, phobic anxiety hostility and interpersonal sensitivity symptoms may be associated with hypersensitivity of human skin. Psychological factors should be taken into consideration in the treatment of patients with sensitive skin

Calcipotriol monotherapy versus calcipotriol plus UVA1 versus calcipotriol plus narrow-band UVB in the treatment of psoriasis

The purpose of this study was to evaluate the efficacy of calcipotriol ointment as monotherapy versus calcipotriol in combination with narrow-band ultraviolet (UV)-B or UVA1 phototherapy and to determine whether calcipotriol in combination with UVA1 is an alternative to calcipotriol with narrow-band UVB phototherapy Forty-five patients with plaque psoriasis were divided into three treatment groups with no significant differences in Psoriasis Area and Severity Index (PASI) scores, mean age, sex or skin type. The total duration of the treatment was 3 months. Regarding PASI score, psoriasis regression was statistically significant between the groups. The response to UVA1 and narrow band UVB with calcipotriol was superior to calcipotriol monotherapy. UVA1 phototherapy with calcipotriol could be an alternative to narrow-band UVB phototherapy with calcipotriol

Objective biophysical findings in patients with sensitive skin

The term sensitive skin has been used to describe a clinical phenomenon of hyperreactivity of the human skin, which develops exaggerated reactions when exposed to external factors. The aim of this study was to determine objective biophysical findings in patients with sensitive skin compared to those individuals with nonsensitive skin. Thirty-two patients with sensitive skin and 30 healthy volunteers with nonsensitive skin were studied. The testing methods included in vivo and in vitro tests: epicutaneous testing (Patch tests); measurement of sebum and hydration of the skin; alkali resistance test; stinging test with lactic acid; reaction to aqueous solution of methyl nicotinate 0.5%, 1.4% and acetyl-b-methylcholine chloride 1:1000; pH measurement; dermographism; and measurement of total and specific IgE. Significant results were observed in the measurement of sebum (p < 0.01) and hydration (p < 0.05) of the skin, in the alkali resistance test (p < 0.05), in the vascular reaction to methyl nicotinate (p < 0.01) and to acetyl-b-methylcholine chloride (p < 0.01) and in the skin response to allergens of the European standard (p < 0. 01) and cosmetic series (p < 0. 05). In addition, the subjective findings of stinging test produced significant results (p < 0.001) as was anticipated. Patients with sensitive skin possess very dry skin with low fatness, which leads to a disturbance of the protective skin barrier function. They also present a hyperreaction of the skin blood vessels, increased transcutaneous penetration of water-soluble chemicals, enhanced immune responsiveness, significant decrease of alkali resistance and a heightened neurosensory stimulation

Evaluation of cytokine serum levels in patients with plaque-type psoriasis

Psoriasis is a chronic debilitating cutaneous disorder that affects both sexes and appears clinically as inflamed, edematous skin lesions covered with a silvery white scale. Strong evidence suggests that immune mechanisms are implicated in its pathogenesis, such as persistent activation of T-lymphocytes, excessive proliferation of keratinocytes and reactivation of proto-oncogenes and other elements. Additionally, several recent studies have demonstrated that cytokines play a significant role in the pathogenesis of the disease, as they can be found in the affected skin of psoriatic patients. In this study we evaluated levels of circulating cytokines in the serum of 45 Greek psoriatic patients before initiation of treatment and compared the results with those in 45 healthy volunteers. According to our findings interleukin (IL)-2, IL- 10, IL- 12 and tumor necrosis factor-alpha (TNF- alpha) levels were statistically significantly elevated in the serum of psoriatic patients before therapy compared with those of controls. IL-6 serum levels did not differ between psoriatic patients and healthy volunteers. Conversely, interferon-gamma serum levels of psoriatic patients were statistically significantly lower than those of healthy volunteers

Identification of human papillomavirus DNA in melanoma biopsy specimens of Greek population

The aim of this retrospective study was to evaluate melanoma biopsy specimens from the Greek population living in the prefecture of Larissa for the presence of human papillomavirus (HPV) DNA and to determine the possible relationship between HPV and clinical outcome in these patients. Twenty-eight melanoma biopsy specimens, 20 from primary cutaneous melanoma and eight from melanoma metastasis were obtained from 28 patients. The biopsy samples were formalin-fixed and paraffin wax-embedded. The control group consisted of three junctional melanocytic nevi, histologically confirmed, and three punch biopsies from normal skin that were obtained from six healthy individuals. The presence and types of HPV DNA were assessed by the amplification of a fragment of the L1 region by consensus primer polymerase chain reaction (PCR) combined with restriction fragment length polymorphism analysis (RFLPA). In each biopsy specimen that was evaluated, HPV 6, HPV 11, HPV 16 and HPV 18 positive controls from genital HPV lesions were included. Five of 28 (17.85%) biopsy melanoma specimens were positive for HPV DNA. Conversely, HPV was not detected in any of the biopsy specimens of the control group (0/6). HPV viral type 16 was found in two samples and HPV 6 DNA in three. Our results regarding the possible relationship between melanoma and HPV DNA were not statistically significant (p > 0.05). These findings suggest that ultraviolet sun exposure remains the main cause of melanoma in our region. The role of cutaneous HPV infection in the pathogenesis of melanoma remains elusive. © 2005 Bioscience Ediprint Inc

Increasing incidence of melanoma in central Greece: A retrospective epidemiological study

The increasing incidence of melanoma in the general population during the last few decades has provoked a great deal of research, aiming to identify the possible relationship between old and new etiological factors involved in the pathogenesis of this tumor The aim of the study was to evaluate the incidence of melanoma in central Greece, especially in the prefecture of Larissa from January 1988 to December 1998. Data were collected from the General Hospital of Larissa. Seventy-one cases of melanoma were studied (41 females, 30 males). The incidence increased from 1.36/100,000 patients during the first year of the study (1988) to 5.2/100, 000 patients in the last year of the study (1998). The patients' skin types were: type 12.8%, type II 52.1%, type III 45.1%. The median age of patients was 61.9 years, 61.4 years in female and 62.5 years in male patients. Concerning their occupation, farmers accounted for 56.3%. Melanomas were most frequently located on head and neck (36.6%), extremities (30.98%) and trunk (11.3%). Superficial spreading melanomas were observed in 44% of the patients and nodular melanomas in 20%. In conclusion, there was a rapid increase in the incidence of melanoma in our region especially during the last 3 years

Real-world treatment patterns, patient-reported outcomes, and effectiveness of flexible-dosing etanercept in patients with plaque psoriasis in Greece

Etanercept is approved for continuous or intermittent use and flexible dosing in plaque psoriasis (PsO). The objectives of this study were to investigate real-world treatment patterns with etanercept in Greek adults with moderate-to-severe PsO. This non-interventional multicenter study included a retrospective-to-prospective (RP) cohort, previously treated with etanercept for ≥24 months and followed for an additional 6 months, and a biologic-naïve, prospective-only (PO) cohort, followed for 6 months after treatment initiation. Parameters assessed included Psoriasis Area and Severity Index (PASI), percentage of body surface area (BSA) affected, Dermatology Life Quality Index (DLQI), and adverse events (AEs). This study enrolled 123 patients (RP, n = 56; PO, n = 67), who mostly adhered to continuous treatment (RP, 68%; PO, 95%). The two cohorts had similar mean baseline-to-endpoint decreases in PASI (-9.5 vs -10.1) and BSA (-11.9 vs -12.3). The PO-CTP population had a mean DLQI baseline-to-endpoint score decrease of -5.8, which was statistically significant and clinically meaningful. Treatment-emergent AE rates were 58.9% (RP) versus 26.9% (PO). These real-world data suggest a similar effectiveness of continuous and intermittent etanercept treatment in Greek patients with PsO. © 2022 Page Press Publications. All rights reserved
