Oxidative Stress Is Increased in Combined Oral Contraceptives Users and Is Positively Associated with High-Sensitivity C-Reactive Protein.

Information concerning the mechanisms underlying oxidative stress and low-grade inflammation in young healthy women predisposing eventually to future diseases is scarce. We investigated the relationship of oxidative stress and high-sensitivity C-reactive protein (hsCRP) in fertile-age women by oral combined contraceptive (OC) use. Caucasian Italian healthy non-obese women (n = 290; 100 OC-users; 190 non-OC-users; mean age 23.2 ± 4.7 years) were analyzed. Blood hydroperoxides, as oxidative stress biomarkers, were assessed by Free Oxygen Radical Test (FORT). Serum hsCRP was determined by an ultra-sensitive method (hsCRP). Markedly elevated oxidative stress (≥400 FORT Units) was found in 77.0% of OC-users and 1.6% of non-OC-users, odds ratio (OR) = 209, 95% CI = 60.9-715.4, p < 0.001. Elevated hsCRP levels ≥ 2.0 mg/L, considered risky for cardiovascular diseases (CVDs), were found in 41.0% of OC-users and 9.5% of non-OC-users, OR = 6.6, 95%CI 3.5-12.4, p < 0.001. Hydroperoxides were strongly positively correlated to hsCRP in all women (rs = 0.622, p < 0.001), in OC-users (rs = 0.442, p < 0.001), and in non-OC-users (rs = 0.426, p < 0.001). Women with hydroperoxides ≥ 400 FORT Units were eight times as likely to have hsCRP ≥ 2 mg/L. In non-OC-users only, hydroperoxides values were positively correlated with weight and body mass index, but negatively correlated with red meat, fish and chocolate consumption. Our research is the first finding a strong positive correlation of serum hydroperoxides with hsCRP, a marker of low-grade chronic inflammation, in young healthy women. Further research is needed to elucidate the potential role of these two biomarkers in OC-use associated side-effects, like thromboembolism and other CVDs.

Update on the Management of Pediatric Psoriasis: An Italian Consensus.

INTRODUCTION: Psoriasis affects children with a considerable burden in early life. Treating pediatric psoriasis is challenging also because of the lack of updated specific guidelines. With the recent approval of several biologics for pediatric psoriasis and the ongoing COVID-19 pandemic, the management of young psoriatic patients is facing major changes. A revision of treatment recommendations is therefore needed. METHODS: In September 2021, a board of six Italian dermatologists convened to update treatment recommendations. The board issued evidence- and consensus-based statements covering relevant areas of pediatric psoriasis, namely: assessment of psoriasis severity, management of children with psoriasis, and treatment of pediatric psoriasis. To reach consensus, the statements were submitted to a panel of 24 experts in a Delphi process performed entirely via videoconference. A treatment algorithm was produced. RESULTS: There was full consensus that psoriasis severity is determined by the extension/severity of skin lesions, site of lesions, and impact on patient quality of life. Agreement was reached on the need for a multidisciplinary approach to pediatric psoriasis and the importance of patient/parents education. The relevance of vaccinations, including COVID-19 vaccination, for psoriatic children was acknowledged by all participants. Management issues that initially failed to reach consensus included the screening for psoriasis comorbidities and early treatment with biologics to prevent them and the use of telemedicine to facilitate patient follow-up. There was full consensus that topical corticosteroids are the first choice for the treatment of mild pediatric psoriasis, while phototherapy and systemic therapy are used in children with moderate-severe psoriasis. According to the proposed treatment algorithm, biologics are the first line of systemic therapy. CONCLUSIONS: Targeted systemic therapies are changing the treatment of moderate-severe pediatric psoriasis, while topical corticosteroids continue to be the first choice for mild disease. Children-centered research is needed to further improve the treatment of pediatric psoriasis.

Long-term proactive management of psoriasis with calcipotriol and betamethasone dipropionate foam: an Italian consensus through a combined nominal group technique and Delphi approach.

BACKGROUND: Although long-term management of psoriasis is paramount, this approach is challenging in clinical practice. In the recent PSO-LONG trial, a fixed-dose combination of betamethasone dipropionate (BD) and calcipotriol (Cal) foam applied twice a week on non-consecutive days for 52 weeks (proactive treatment) reduced the risk of relapse. However, the role of Cal/BD foam in the long-term management of psoriasis needs further clarifications. The ProActive Management (PAM) program, a nationwide Italian project, aims at reaching a consensus on the role of proactive management of psoriasis. METHODS: A steering committee generated some statements through the nominal group technique (NGT). The statements were voted by an expert panel in an adapted Delphi voting process. RESULTS: Eighteen statements were proposed, and the majority of them (14/18) reached a consensus during the Delphi voting. The need to provide long-term proactive topical treatment to reduce the risk of relapse for the treatment of challenging diseases sites or in patients where phototherapy or systemic therapies are contraindicated/ineffective was widely recognized. A consensus was reached about the possibility to associate the proactive treatment with systemic and biological therapies, without the need for dose intensification, thus favoring a prolonged remission. Moreover, the proactive treatment was recognized as more effective than weekend therapy in increasing time free from relapses. Approaches to improve adherence, on the other hand, need further investigation. CONCLUSIONS: The inclusion in guidelines of a proactive strategy among the effective treatment options will be a fundamental step in the evolution of a mild-moderate psoriasis therapeutic approach.

Comparison of clinical effects, trough and peak levels between branded and generic formulation of Cyclosporine in stable psoriatic patients.

BACKGROUND: Cyclosporine A (CyA) is a drug for moderate-to-severe psoriasis. Recently, a generic formulation has been approved as bioequivalent to the branded one. The guidelines for the bioequivalence for critical-dose drugs with a narrow therapeutic range, such as CyA, are questionable. Therefore, it is important to assess the clinical outcome and the pharmacokinetics of different formulations in various patient groups. The current literature lacks of this information in dermatology. The primary objective of this prospective study is to investigate the clinical equivalence (in terms of maintenance of clinical effect) between the generic formulation of CyA and its branded one in patients with psoriasis. A secondary objective is to analyze their trough (C0) and peak levels (C2). METHODS: Twenty patients with stable psoriasis under treatment with the branded CyA were monitored in terms of clinical efficacy (psoriasis area severity index, PASI), safety (laboratory values), and their pharmacokinetics utilizing trough (C0) and peak plasma concentration (C2). The same patients were subsequently shifted to the generic formulation for comparison. RESULTS: In our sample the efficacy of the two formulations was equal in most cases (P=0.863). A non-significant difference between the C0 and C2 of the branded CyA compared to the generic one emerged (respectively P=0.738 and P=0.695). CONCLUSIONS: The branded and the generic formulations of CyA seem to be not only bioequivalent, but also comparable in terms of clinical efficacy in patients with psoriasis. However, larger samples are required to confirm these findings.

Annular and arciform lesions of the palms as unique manifestations of secondary syphilis.

We describe a patient presenting with annular-arciform symmetric lesions of the palms as the unique manifestation of secondary syphilis. The polymorphism of skin lesions in secondary syphilis depends entirely on the degree of inflammatory infiltrate, the level of vascular involvement and the resulting ischemia of the skin. Besides the transient and diffuse maculo-papules (roseola syphilitica), secondary syphilis skin lesions may have different morphology and shape. It has already been reported that in cases of reinfections by Treponema pallidum the skin lesions may be arciform, as in our patient, and asymmetric. Indeed, previous syphilis may attenuate the clinical and laboratory manifestations of a new infection with T.pallidum, that occurs with less severe skin manifestations or presents as latent syphilis. However, to our knowledge, annular-arciform lesions of the palms as unique manifestations of secondary syphilis have never been described. Clinicians should be well trained to recognize the atypical presentations of syphilis, especially in patients who have already received a syphilis diagnosis, since its incidence is steadily increasing in Europe, especially in men having sex with men.

Interleukin 1 receptor antagonist gene variable number of tandem repeats polymorphism and cutaneous melanoma.

Immunity and cytokines serve crucial roles in cutaneous melanoma. The present study investigated whether a variable number tandem repeat (VNTR) polymorphism of interleukin-1 receptor antagonist (IL-1RA) gene (IL-1RN) located in intron 2 (rs2234663) is associated with cutaneous melanoma. A total of 515 subjects were studied, 133 of which were cutaneous melanoma cases (72 stage I+II non-metastatic melanoma cases and 61 stage III+IV metastatic melanoma cases), and 382 subjects were matching healthy controls from the Friuli-Venezia-Giulia Region located in Northeast Italy, an area with a high melanoma incidence. The IL-1RN-VNTR polymorphism was determined by DNA fragment length analysis following PCR amplification. According to the number of 86-bp repeats, five different IL-1RN alleles were identified: Allele 1 (4-repeats), allele 2 (2-repeats, short allele), allele 3 (5-repeats), allele 4 (3-repeats) and allele 5 (6-repeats). Alleles with three or more 86-bp repeats, i.e. allele 1, 3, 4 and 5 were collectively denoted as long (L) repeats. The present study revealed that IL-1RN-VNTR 1/2 and 2/L genotypes were more frequent among patients with cutaneous melanoma (43.6 and 45.1%, respectively) compared with healthy controls [29.6 and 30.6%, respectively; odds ratio (OR), 1.84; CI, 1.22-2.77; P=0.003; and OR, 1.66; CI, 1.24-2.79; P=0.002, respectively]. Conversely, the IL-1RN-VNTR 1/1 genotype was less frequent among melanoma cases (45.9%) compared with healthy controls (57.9%; OR, 0.62; CI, 0.41-0.92; P=0.017). Comparison of metastatic vs. non-metastatic melanoma cases identified no significant differences. The present study first demonstrated that carriage of the 1/1 IL-1RN-VNTR genotype was protective, whereas 1/2 and 2/L was a risk factor for patients with cutaneous melanoma vs. healthy controls. The short allele 2 was associated with higher expression levels of IL-1RA, a potent competitive inhibitor of the proinflammatory cytokines IL-1α and IL-1ß. VNTR-IL-1RN polymorphism may affect susceptibility to melanoma and, thus, it is a potential novel diagnostic biomarker for melanoma. The present study increased the understanding of genetic melanoma susceptibility/carcinogenesis, and may indicate novel strategies in the personalized prevention of cutaneous melanoma.

A multicenter retrospective case-control study on Suspension of TNF-inhibitors and Outcomes in Psoriatic patients (STOP study).

BACKGROUND: There is limited information on patients undergoing withdrawal after long-term treatment with anti-TNF alpha drugs and their clinical evolution during the post-interruption period in real-life settings. The purpose of the present retrospective case-control study was to provide a clearer insight into the clinical management of psoriatic patients with adequate response to long-term adalimumab, etanercept and infliximab treatment once these biologic agents are interrupted. METHODS: A total of 270 patients undergoing anti-TNF alpha agents discontinuation and 253 controls treated with a continuous regimen were enrolled. The primary endpoint was the change in disease activity in each study group over six months (or until treatment of psoriatic recurrence) as measured by the PASI score every month. Then, we evaluated the rate of and time to relapse, the rate of clinical worsening (PASI≥5) and the clinical variables influencing the loss of response. RESULTS: Our study showed that about 50% of patients achieving a long-term and optimal response to the aforementioned anti-TNF alpha agents did not experience any relapse over a 6-month follow-up period after withdrawal. We also observed that subjects displaying a complete remission (PASI=0) at anti-TNF alpha therapy withdrawal experienced less frequently disease worsening and/or relapse compared to subjects having a PASI>0. CONCLUSIONS: Our findings confirmed that all three anti-TNF alpha agents tend to retain their effectiveness upon re-administration in case of recurrence, even if they have been previously used for long time.

BsmI (rs1544410) and FokI (rs2228570) vitamin D receptor polymorphisms, smoking, and body mass index as risk factors of cutaneous malignant melanoma in northeast Italy.

OBJECTIVE: : To investigate whether vitamin D receptor gene (VDR) BsmI-rs1544410 and FokI-rs2228570 polymorphisms, smoking duration, and body mass index (BMI) are risk factors for cutaneous melanoma, especially metastatic melanoma. METHODS: : We studied 120 cutaneous melanoma cases [68 stage I and II non-metastatic melanoma (NMetM) patients, plus 52 Stage III and IV metastatic melanoma (MetM) patients], and 120 matching healthy controls from northeast Italy. VDR polymorphisms were measured by restriction fragment length polymorphism analysis. Absence or presence of BsmI and FokI restriction sites was denoted by " B" and " F" or by " b" and " f," respectively. RESULTS: : VDR-BsmI bb genotype was more frequent among MetM (32.7%) than among NMetM cases (13.2%), with odds ratio (OR)=3.18. Comparison of all melanoma patients vs healthy controls showed that the following biomarkers were at risk: ≥20 years of smoking (OR=2.43); ≥20 years of smoking combined with bb (OR=4.78), Bb+bb (OR=2.30), Ff (OR=3.04), and Ff+ff (OR=3.08); obesity (BMI>30 kg/m2) alone (OR=3.54); and obesity combined with Bb+bb (OR=3.52), Ff (OR=4.78), and Ff+ff (OR=6.56). Comparison of MetM vs NMetM patients revealed that the following biomarkers were at risk: ≥20 years of smoking (OR=2.39), ≥20 years of smoking combined with bb (OR=5.13), Bb+bb (OR=3.07), and Ff+ff (OR=2.66); and obesity combined with Bb+bb (OR=5.27), Ff (OR=6.28), and Ff+ff (OR=9.18). Triple combination of ≥20 years of smoking, obesity, and Bb+bb yielded OR=9.65 for melanoma patients vs healthy controls and OR=12.2 for MetM vs. NMetM patients. CONCLUSIONS: : Risk factors for cutaneous MetM include two VDR polymorphisms combined with smoking duration and obesity. Results suggest gene-environment implications in melanoma susceptibility and severity. Future studies in larger cohorts and in subjects with different genetic background are warranted to extend our findings.

Immunohistochemical evaluation of vitamin D receptor (VDR) expression in cutaneous melanoma tissues and four VDR gene polymorphisms.

OBJECTIVE: : Vitamin D receptor (VDR) mediates vitamin D activity. We examined whether VDR expression in excised melanoma tissues is associated with VDR gene (VDR) polymorphisms. METHODS: : We evaluated VDR protein expression (by monoclonal antibody immunostaining), melanoma characteristics, and carriage of VDR-FokI-rs2228570 (C>T),VDR-BsmI-rs1544410 (G>A),VDR-ApaI-rs7975232 (T>G), andVDR-TaqI-rs731236 (T>C) polymorphisms (by restriction fragment length polymorphism). Absence or presence of restriction site was denoted by a capital or lower letter, respectively: " F" and " f" for FokI, " B" and " b" for BsmI, " A" and " a" for ApaI, and " T" and " t" for TaqI endonuclease. Seventy-four Italian cutaneous primary melanomas (52.1±12.7 years old) were studied; 51.4% were stage I, 21.6% stage II, 13.5% stage III, and 13.5% stage IV melanomas. VDR expression was categorized as follows: 100% positivevs. <100%; over the median 20% (high VDR expression) vs. ≤20% (low VDR expression); absence vs. presence of VDR-expressing cells. RESULTS: : Stage I melanomas, Breslow thickness of <1.00 mm, level II Clark invasion, Aa heterozygous genotype, and AaTT combined genotype were more frequent in melanomas with high vs. low VDR expression. Combined genotypes BbAA, bbAa, AATt, BbAATt, and bbAaTT were more frequent in 100% vs. <100% VDR-expressing cells. Combined genotype AATT was more frequent in melanomas lacking VDR expression (odds ratio=14.5; P=0.025). VDR expression was not associated with metastasis, ulceration, mitosis >1, regression, tumor-infiltrating lymphocytes, tumoral infiltration of vascular tissues, additional skin and non-skin cancers, and melanoma familiarity. CONCLUSIONS: : We highlighted that VDR polymorphisms can affect VDR expression in excised melanoma cells. Low VDR expression in AATT carriers is a new finding that merits further study. VDR expression possibly poses implications for vitamin D supplementation against melanoma. VDR expression and VDR genotype may become precise medicinal tools for melanoma in the future.

Oxidative Stress in Female Athletes Using Combined Oral Contraceptives.

BACKGROUND: Oxidative stress in female athletes is understudied. We investigated oxidative stress in sportswomen of different disciplines according to combined oral contraceptive (OC) use and lifestyle/alimentary habits. METHODS: Italian sportswomen (n = 144; mean age 23.4 ± 4.2 years; body mass index 21.2 ± 2.2 kg m-2; sport activity 9.2 ± 4.1 h week-1) were analyzed; 48 % were volleyball players, 12.5 % soccer players, 10.4 % track-and-field sports, and followed by other disciplines' athletes. Oxidative stress was evaluated by free oxygen radical test (FORT) assessing blood hydroperoxides and free oxygen radical defense (FORD) assay evaluating antioxidant capacity in OC users (n = 42) compared to non-OC users. RESULTS: Elevated oxidative stress levels (≥310 FORT units) were found in 92.9 % of OC users and in 23.5 % of non-OC users (crude OR = 42, 95 % CI 12-149, p < 0.001; adjusted OR = 60, 95 % CI 11-322, p < 0.001). Continuous values of hydroperoxides were twofold higher in OC users versus non-OC users (median 484 versus 270 FORT units, p < 0.001) and were inversely related to FORD units in OC users (p = 0.01). Hydroperoxides were not associated with weekly hours of exercise. In OC users, lifestyle/alimentary habits were not correlated to hydroperoxides. In non-OC users only, hydroperoxide values were positively correlated with weight and BMI and inversely correlated with chocolate and fish consumption. CONCLUSIONS: The markedly elevated oxidative stress we revealed in OC-user athletes could be detrimental to physical activity and elevate cardiovascular risk (as thromboembolism). Further research is needed to extend our results, to clarify the biochemical pathways leading to increased hydroperoxides (mainly lipid peroxides) and reduced antioxidant defense, and to elucidate the potential effects on athletic performance. OC use should be considered when developing gender-focused strategies against oxidative stress.

Ulcus vulvae acutum - A case of genital ulcers in adolescent girl.

Ulcus vulvae acutum is a rare clinical condition characterized by the presence of multiple acute painful genital ulcers of non-venereal origin associated with systemic symptoms in young women. The aetiopathogenesis of the disease is not fully understood, although recent reports have associated it with the Epstein-Barr virus. Diagnosis is difficult and generally made by exclusion after venereal diseases, and autoimmune, inflammatory, traumatic, and neoplastic causes. We describe a case of adolescent female with an episode of ulcus vulvae acutum associated with infectious mononucleosis. The diagnosis was supported by the clinical symptoms, elevated circulating levels of liver enzymes, positive EBV serology, cervical and inguinal lymphadenomegaly, and hepatosplenomegaly. The patient presented a history of aphthous stomatitis. Negative Pathergy test and the absence of any other related symptoms allowed us to exclude the Behçhet syndrome. Lesions healed with no sequelae or recurrences.

BsmI, ApaI and TaqI Polymorphisms in the Vitamin D Receptor Gene (VDR) and Association with Lumbar Spine Pathologies: An Italian Case-Control Study.

Three adjacent single nucleotide polymorphisms of the vitamin D receptor gene (VDR) BsmI (rs1544410), ApaI (rs7975232), and TaqI (rs731236) are commonly studied in several pathologies. We aimed to evaluate the distribution of VDR BsmI, ApaI, and TaqI allele, genotype, and haplotype frequencies in an Italian cohort of 266 patients with lumbar spine disorders assessed by Magnetic Resonance Imaging and 252 asymptomatic controls. The exposure to putative risk factors was evaluated by a questionnaire. Polymorphisms were detected by PCR-RFLP and TaqMan® SNP Genotyping Assay. The results were statistically adjusted for the identified conventional risk factors. The three SNPs were in linkage disequilibrium. For all cases BbAaTT was a 3-fold risk factor OR = 3.38), whereas bbAATT (OR = 0.22), and bbaaTT (OR = 0.47) genotypes were found to be protective. Specifically, for patients affected by disc herniation only (n = 88) and all lumbar pathologies excluding stenosis and/or spondylolistesis (n = 215) B allele, Bb, Aa, and BbAaTT genotypes were risky, whereas b allele, bb, aa, and bbaaTT genotypes were protective. In patients affected by osteochondrosis with or without disc hernation (n = 50), T allele, Aa, and bbAaTT genotypes were risky, whereas t allele, AA, tt genotypes were protective. In patients affected by stenosis and/or spondylolistesis (n = 51) no significant associations were found. This is the first study showing an association of the three genetic VDR variants BsmI, ApaI, and TaqI and lumbar spine pathologies. Our study contributes to delineate genetic risk factors for specific subgroups of patients with lumbar spine pathologies highlighting the importance of haplotype analysis, and of detailed clinical evaluation of the patients for identification of genetic biomarkers.

Clinical and Capillaroscopic Modifications of the Psoriatic Plaque during Therapy: Observations with Oral Acitretin.

Psoriasis is considered to be an inflammatory autoimmune disease, where angiogenesis plays an undefined pathogenetic role. The well-known changes of the superficial microvasculature in the psoriatic plaque can be easily assessed in vivo by videocapillaroscopy. In the last years, several studies reported the clinical and capillaroscopic response of the psoriatic plaque during different topical and systemic treatments. In the present work we evaluated the effects of acitretin (0.8 mg/kg/day) on videocapillaroscopic alterations and the clinical response in 11 patients affected by plaque psoriasis at the baseline (T0) and after 4 (T1), 8 (T2), and 12 (T3) weeks. A clinical improvement during the treatment with a complete clinical healing of the plaque in 7 of the 11 patients was observed. The typical "basket-weave" capillaries of the psoriatic lesions showed a reduction of 65.4% in diameter at the end of the study; only 3 patients returned to a normal capillaroscopic pattern. As observed during previous our studies, we found a discrepancy between clinical and capillaroscopic results, with a far greater improvement in the first than in the second. This finding could be in agreement with a secondary role of blood vessels in the pathogenesis and persistence of psoriatic lesions.

Narrow band-ultraviolet B versus clobetasol propionate foam in the treatment of vitiligo: a retrospective study.

INTRODUCTION: Several therapeutic options are available for the treatment of vitiligo; among these phototherapy and topical steroids are the most widely documented. A topical formulation of 0.05% clobetasol propionate foam (CPF) has been introduced in the market, but no data are available about the efficacy and tolerability of this new formulation in the treatment of vitiligo. The aim of this study was to investigate the efficacy and tolerability of CPF in the treatment of vitiligo, in comparison with narrowband-ultraviolet B (NB-UVB) phototherapy. METHODS: The medical records of the first 60 vitiligo patients treated with NB-UVB phototherapy or with CPF were selected. Response to the treatment was determined for each anatomic site (neck, upper and lower limbs, trunk, hands/wrists, feet/ankles). Based on the area of repigmentation, treatment outcome was calculated according to a scale ranging from 0 (absent) to 4 (excellent). The incidence of adverse effects was also noted as a secondary endpoint. Significance level was set at P = 0.05. RESULTS: For each anatomic site, statistical analyses demonstrated that the efficacy of CPF was significantly higher compared to NB-UVB. Side effects occurred in 4 patients (13.33%) in the CPF group compared to none in the NB-UVB group. DISCUSSION: Clobetasol propionate has been used in vitiligo in different vehicles, but never in foam. The data showed that CPF is effective and seems to be superior to NB-UVB phototherapy, with furthermore a good safety profile. CONCLUSION: This new foam formulation of clobetasol propionate may expand the options currently available for vitiligo therapy; however, further investigations are needed to confirm our preliminary observations.
