Helicobacter Pylori infection in children with inflammatory bowel disease: a prospective multicenter study.

BACKGROUND: The relationship between Helicobacter-pylori(Hp)infection and inflammatory-bowel-disease(IBD) in pediatric-patients remains controversial. We aimed to assess the Hp-infection occurrence in newly-diagnosed pediatric-patients with IBD compared to no-IBD patients. Additionally, we aimed to examine differences in clinical-activity-index(CAI) and endoscopic-severity-score(ESS)between IBD-patients with and without Hp-infection, at baseline and at 1-year-follow-up(FU), after eradication-therapy(ET). METHODS: IBD diagnosis was based on Porto-criteria, and all patients underwent gastroscopy at baseline and 1-year FU. For Crohn's-disease(CD) and ulcerative colitis(UC), IBD-CAI and -ESS were classified using PCDAI/SES-CD and PUCAI/UCEIS, respectively. RESULTS: 76 IBD-patients were included in the study[35 F(46.1%),median-age 12(range 2-17)]. CD and UC were diagnosed in 29(38.2%) and 45(59.2%)patients, respectively, and unclassified-IBD in two(2.6%)patients. Non-IBD patients were 148[71 F(48.0%),median-age 12(range 1-17)]. Hp-infection at baseline was reported in 7(9.2%) and 18(12.2%)IBD and non-IBD patients, respectively(p = 0.5065). The 7 IBD patients with Hp infection were compared to 69 IBD patients without Hp-infection at baseline evaluation, and no significant differences were reported considering CAI and ESS in these two groups. At 1-year FU, after ET, IBD patients with Hp infection improved, both for CAI and ESS, but statistical significance was not reached. CONCLUSION: The occurrence of Hp-infection did not differ between IBD and no-IBD patients. No differences in CAI or ESS were observed at the diagnosis, and after ET no worsening of CAI or ESS was noted at one-year FU, between Hp-positive and -negative IBD patients.

Is Melanoma Progression Affected by Thyroid Diseases?

Clinical and epidemiological evidence indicate a relationship between thyroid diseases and melanoma. In particular, the hypothyroidism condition appears to promote melanoma spread, which suggests a protective role of thyroid hormones against disease progression. In addition, experimental data suggest that, in addition to thyroid hormones, other hormonal players of the hypothalamic-pituitary-thyroid (HPT) axis, namely the thyrotropin releasing hormone and the thyrotropin, are likely to affect melanoma cells behavior. This information warrants further clinical and experimental studies in order to build a precise pattern of action of the HPT hormones on melanoma cells. An improved knowledge of the involved molecular mechanism(s) could lead to a better and possibly personalized clinical management of these patients.

Risk of Depression Associated With Finasteride Treatment.

BACKGROUND: Finasteride is one of several inhibitors of the 5α-reductase that converts testosterone to dihydrotestosterone used to treat hair loss and benign prostatic enlargement. Emerging clinical observations indicate that such treatment may be associated with depression, anxiety, and possibly increased suicidal risks, in addition to sexual dysfunction, even after its discontinuation. METHODS: We carried out a systematic review of reports pertaining to association of finasteride treatment with clinical depression or other adverse psychiatric effects. We analyzed reported risks of depression by pooling of rates and by meta-analysis of comparisons of subjects treated with finasteride or not. FINDINGS: Crude pooled rates of depressive symptoms with versus without finasteride were 3.33% (confidence interval, 3.22%-3.44%) versus 2.54% (2.44%-2.64%); random-effects meta-analysis yielded an odds ratio of 2.14 (1.40-3.27) (both P < 0.0001). In addition, risk of suicidal ideation or behavior was greater with versus without finasteride (21.2% [21.0%-21.5%] vs 14.0% [13.8%-14.2%], P < 0.0001), and risk of sustained sexual dysfunction was high (60.1% [37.3%-82.9%]). CONCLUSIONS: The findings support a growing impression that finasteride is associated with adverse psychiatric effects that can persist in association with sexual dysfunction after discontinuing finasteride treatment.

Multiple Sclerosis Treatment and Melanoma Development.

Therapy of multiple sclerosis (MS) with disease-modifying agents such as natalizumab or fingolimod has been associated with the development of cutaneous melanoma. Here we briefly revise literature data and report of a case of a 48-year old woman who developed a melanoma and several atypical naevi after sub sequential treatment with natalizumab (1 year) and fingolimod (7 years). By immunohistochemistry we observed the presence of T cells and leukocyte infiltration as well as of vascular endothelial growth factor (VEGF)-A expression in the patient melanoma biopsy. Then, we analyzed proliferation, migration and VEGF-A expression in three melanoma cell lines and found out that both natalizumab and fingolimod inhibited tumor cell proliferation but promoted or blocked cell migration depending on the cell line examined. VEGF-A secretion was augmented in one melanoma cell line only after fingolimod treatment. In conclusion, our in vitro data do not support the hypothesis of a direct action of natalizumab or fingolimod on melanoma progression but acting on the tumor microenvironment these treatments could indirectly favor melanoma evolution.

Treatment of refractory conjunctivitis associated to dupilumab with topical pimecrolimus applied to the eyelid skin.

Patients with atopic dermatitis commonly experience ophthalmic complications, and a higher incidence of conjunctivitis has been observed during treatment with dupilumab. We present the case of a 49-year-old woman with persistent severe atopic dermatitis who complained of refractory conjunctivitis associated with dupilumab. Ocular examination showed features of atopic conjunctivitis for which an external topical application to the eyelids of pimecrolimus 10 mg/g cream was prescribed. The patient showed substantial clinical remission after only 12 days. This case was remarkable as the medication applied externally to the eyelid skin was effective in treating the conjunctival involvement possibly due to penetration of pimecrolimus through the eyelid layers. Further studies are needed to support the use of this drug for dupilumab-related conjunctivitis.

Thyroid diseases and skin autoimmunity.

The skin is the largest organ of the body, at the boundary with the outside environment. Primarily, it provides a physical and chemical barrier against external insults, but it can act also as immune organ because it contains a whole host of immune-competent cells of both the innate and the adaptive immune systems, which cooperate in eliminating invading pathogens following tissue injury. On the other hand, improper skin immune responses lead to autoimmune skin diseases (AISD), such as pemphigus, bullous pemphigoid, vitiligo, and alopecia. Although the interplay among genetic, epigenetic, and environmental factors has been shown to play a major role in AISD etiology and progression, the molecular mechanisms underlying disease development are far from being fully elucidated. In this context, epidemiological studies aimed at defining the association of different AISD with other autoimmune pathologies revealed possible shared molecular mechanism(s) responsible for disease progression. In particular, over the last decades, a number of reports have highlighted a significant association between thyroid diseases (TD), mainly autoimmune ones (AITD), and AISD. Here, we will recapitulate the epidemiology, clinical manifestations, and pathogenesis of the main AISD, and we will summarize the epidemiological evidence showing the associations with TD as well as possible molecular mechanism(s) underlying TD and AISD pathological manifestations.

An uncommon localization of black heels in a free climbing instructor.

Black heels, also known as talon noir or calcaneal petechiae, are asymptomatic superficial cutaneous haemorrhages of the feet, mostly seen as post-traumatic lesions in young athletic individuals who practice sports such as tennis, football, or gymnastics. Here, we present a case of black heels in a young male rock climber.

Condyloma acuminata and mollusca contagiosa: a giant manifestation in a patient with lupus.

A 27-year-old woman with systemic lupus erythematosus since childhood and treated with immunosuppressive therapy for many years was referred to our clinic for the presence of widespread condylomatosis and mollusca contagiosum localized in the genital area. These lesions appeared 4 years before and had been treated with both surgery and topical immunomodulation therapy without resolution. The patient stated that she had two sexual partners in that period, who showed no skin lesions. Cutaneous examination showed about 30 to 40 molluscoid lesions of 0.5 cm to 2 cm in diameter and widespread cauliflower-like condyloma acuminata (Figure) spread on the vulvovaginal and perianal region without any symptoms. At the time of observation, she was under treatment with corticosteroids and mycophenolate mofetil.

Long-Term Drug Survival and Effectiveness of Secukinumab in Patients with Moderate to Severe Chronic Plaque Psoriasis: 42-Month Results from the SUPREME 2.0 Study.

Purpose: SUPREME, a phase IIIb study conducted in Italy, demonstrated safety and high efficacy of secukinumab for up to 72 weeks in patients with moderate-to-severe plaque-type psoriasis. SUPREME 2.0 study aimed to provide real-world data on the long-term drug survival and effectiveness of secukinumab beyond 72 weeks. Patients and Methods: SUPREME 2.0 is a retrospective observational chart review study conducted in patients previously enrolled in SUPREME study. After the end of the SUPREME study, eligible patients continued treatment as per clinical practice, and their effectiveness and drug survival data were retrieved from medical charts. Results: Of the 415 patients enrolled in the SUPREME study, 297 were included in SUPREME 2.0; of which, 210 (70.7%) continued secukinumab treatment throughout the 42-month observation period. Patients in the biologic-naïve cohort had higher drug survival than those in the biologic-experienced cohort (74.9% vs 61.7%), while HLA-Cw6-positive and HLA-Cw6-negative patients showed similar drug survival (69.3% and 71.9%). After 42 months, Psoriasis Area and Severity Index (PASI) 90 was achieved by 79.6% of patients overall; with a similar proportion of biologic-naïve and biologic-experienced patients achieving PASI90 (79.8% and 79.1%). The mean absolute PASI score reduced from 21.94 to 1.38 in the overall population, 21.90 to 1.24 in biologic-naïve and 22.03 to 1.77 in biologic-experienced patients after 42 months. The decrease in the absolute PASI score was comparable between HLA-Cw6-positive and HLA-Cw6-negative patients. The baseline Dermatology Life Quality Index scores also decreased in the overall patients (10.5 to 2.32) and across all study sub-groups after 42 months. Safety was consistent with the known profile of secukinumab, with no new findings. Conclusion: In this real-world cohort study, secukinumab showed consistently high long-term drug survival and effectiveness with a favourable safety profile.

In papillary thyroid carcinoma BRAFV600E is associated with increased expression of the urokinase plasminogen activator and its cognate receptor, but not with disease-free interval.

CONTEXT: It has been suggested that patients with papillary thyroid cancer (PTC) harbouring the BRAF(V600E) mutation have a worse prognosis. We showed in PTC that high levels of urokinase plasminogen activator (uPA) and its cognate receptor (uPAR) inversely correlate with disease-free interval (DFI). OBJECTIVES: To investigate the effects of BRAF(V600E) on the expression of uPA and uPAR and to evaluate the prognostic relevance of BRAF(V600E) alone or in combination with uPA and uPAR. DESIGN/SETTING/PATIENTS/INTERVENTION: The case study included 91 patients with PTC. All patients underwent thyroidectomy and radioiodine therapy. Follow-up was available for 75 patients. MAIN OUTCOME MEASURES: The BRAF(V600E) mutation was analysed by sequencing and mutant allele-specific PCR amplification; uPA and uPAR expression by quantitative RT-PCR. RESULTS: BRAF(V600E) was found in 44 of the 91 patients and associated with older age, but not with high-risk clinicopathological features. Urokinase PA and uPAR mRNA levels were higher in tumour tissues by 9·51 ± 1·30 and 4·64 ± 0·44 fold, respectively, compared to normal matched tissues, being significantly higher in BRAF(V600E) -positive patients. In vitro induction of BRAF(V600E) in PCCL3 cells caused a significant increase in both uPA and uPAR mRNAs. Higher levels of uPA and uPAR correlated with lymph node metastases, TNM stage and disease recurrences. Kaplan-Meier and multivariate analyses demonstrated that uPA and uPAR were associated with shorter DFI, while the BRAF(V600E) was not. CONCLUSION: In PTC, BRAF(V600E) induces uPA and uPAR expression. The latter, but not BRAF(V600E) , associates with advanced stages and shorter DFI. If confirmed in larger case studies, they may represent reliable prognostic markers for more accurate risk stratification and postoperative decision-making in patients with PTC.

Micronutrients (Other than iron) and Helicobacter pylori infection: a systematic review.

BACKGROUND: Many micronutrients depend on a healthy stomach for absorption. Helicobacter pylori chronic gastritis may alter gastric physiology affecting homeostasis of vitamins and minerals. OBJECTIVES: Systematic review to assess whether H. pylori infection is associated with reduced micronutrient levels (other than iron) in the plasma or gastric juice and whether low micronutrient levels are modified by eradication treatment. METHOD: Medline was searched for relevant publications from inception to June 2010. Studies describing micronutrient levels in H. pylori-infected and not-infected adults and/or the effect of eradication treatment on micronutrient levels were included. FINDINGS: Fifty-two publications were selected: 46 investigated the association between H. pylori infection and reduced micronutrient levels and 14 the effect of eradication treatment on micronutrient levels. Sixty-four studies investigated vitamins (23 ascorbic acid, four ß-carotene, 21 cobalamin, 11 folate, and five α-tocopherol) and 10 addressed minerals (one calcium, one copper, one magnesium, one phosphorus, three selenium, and three zinc). Pooled standardized mean differences in micronutrient levels showed positive associations with H. pylori infection for ascorbic acid (gastric juice, -1.087) and cobalamin (-0.744), and a positive effect of eradication treatment, which increased ascorbic acid in the gastric juice (-1.408) and serum cobalamin (-1.910). No significant association between infection and low folate levels was observed. Meta-analyses for other micronutrients were not performed owing to insufficient data. CONCLUSIONS: Meta-analyses indicate that H. pylori infection is associated with reduced levels of ascorbic acid and cobalamin, supported by the positive effect of eradication treatment. For other micronutrients, further studies are needed.

Deep Sequencing of Immunoglobulin Genes Identifies a Very Low Percentage of Monoclonal B Cells in Primary Cutaneous Marginal Zone Lymphomas with CD30-Positive Hodgkin/Reed-Sternberg-like Cells.

The spectrum of cutaneous CD30-positive lymphoproliferative disorders encompasses both inflammatory and neoplastic conditions. CD30+ Hodgkin and Reed-Sternberg-like cells have been occasionally reported in primary cutaneous marginal zone lymphoma, where they are thought to represent a side neoplastic component within a dominant background of lymphomatous small B cells. Herein, we describe the histological and molecular findings of three cases of primary cutaneous marginal zone lymphomas with CD30+ H/RS cells, in which next-generation sequencing analysis revealed the clonal population to consist in less than 5% of the cutaneous B-cell infiltrate, providing a thought-provoking focus on a possible main role for CD30+ cells in primary cutaneous marginal zone lymphoproliferations.

Biosimilar versus originator etanercept: a real-life clinical study.

BACKGROUND: Over the last few years, novel therapeutic approaches based on the use of monoclonal antibodies against cytokines, or their cognate receptors, involved in psoriasis progression have shown remarkable results, being capable to reduce disease progression and increase patient's quality of life. Among these is etanercept (Enbrel®, Pfizer, Sandwich, UK) and its biosimilar compound SB4 (Benepali®, Samsung Bioepis, Delft, The Netherlands), both approved for the treatment of moderate to severe psoriasis. Aim of the present study was to evaluate in a less controlled environment, such as real-life, the actual bioequivalence between the etanercept (ETN) and the SB4 in term of safety, efficacy and patient's quality of life. METHODS: For this purpose, we analyzed a case study consisting of 65 patients affected by plaque psoriasis, with or without psoriatic arthritis at our dermatological outpatient center of Sant'Andrea Hospital in Rome, all of them under treatment with either ETN or the biosimilar SB4 drug for at least 3 months. The indicators used to evaluate the effectiveness of the therapies were the Psoriasis Area and Severity Index, the Visual Analogue Scale (VAS) for itch, the VAS for pain, and the Dermatology Life Quality Index. RESULTS: The results showed no significant differences among the two drugs in all the analyzed parameters confirming the equivalence between the ETN and its biosimilar SB4. CONCLUSIONS: Overall, we can confirm the overlapping clinical efficacy between ETN and its biosimilar SB4 drug and that even in an uncontrolled environment such as real-life, the biosimilar drugs are an excellent opportunity to reduce health costs allowing to expand the audience of patients who can benefit from these innovative treatments.

Real-world outcomes in patients with moderate-to-severe plaque psoriasis treated with guselkumab for up to 1 year.

BACKGROUND: Real-world data on guselkumab, especially at times >6 months, are limited. RESEARCH DESIGN AND METHODS: We performed a longitudinal, retrospective analysis on 307 patients with moderate-severe chronic plaque psoriasis (Psoriasis Area Severity Index [PASI] >10) treated with guselkumab for up to 12 months. MAIN OUTCOME MEASURES: PASI 75, PASI 90, and PASI 100 were assessed at baseline and at 4, 12, 20, 28, 36, 44, and 52 weeks. RESULTS: At 12 weeks, PASI 75, PASI 90, and PASI 100 were achieved in 56.4%, 33.6%, and 24.1% of patients, respectively. At 52 weeks, PASI 75, PASI 90, and PASI 100 were achieved in 82.7%, 68.7%, and 51.1% of patients, respectively. Patients without comorbidities and those naïve to previous biological therapy had better responses. The mean Dermatology Life Quality Index score decreased from 14.0 at baseline to 3.1 at 12 weeks and 1.6 at 6 months, which was maintained at later times. Similar improvements were seen in pruritus visual analog scale. CONCLUSIONS: Guselkumab maintains its efficacy for up to 12 months among responders in a real-world cohort of patients with moderate-severe plaque psoriasis, confirming data from prior real-world studies with smaller cohorts and shorter duration of follow-up.

Role of radiation therapy in mycosis fungoides refractory to systemic therapy.

The long natural history of early stage mycosis fungoides (MF) makes its management a difficult problem. Skin lesions are sensitive to different therapies and a variety of treatment modalities have been used, such as topical nitrogen mustard, puvatherapy, UV-B, retinoids, radiation therapy, extracorporal photopheresis and systemic chemotherapy. For patients with refractory early stage MF, treatment selection is made by clinical parameters such as the age, sex and performance status of the patients, as well as the institutional expertise and the toxicity profiles of the different therapeutic approaches. We report radiation therapy in a relapsed/resistant stage IB patient with mycosis fungoides treated with local radiation therapy for symptomatic progression unresponsive to bexarotene therapy. Total skin electron beam therapy has been employed in early stage and for limited skin failure MF, while the role of local radiation therapy in MF is less defined. In our experience local radiotherapy has proved to be a very efficient, tolerable and cost effective approach in patients with MF unresponsive to systemic approaches.
