ABSTRACT

OBJECTIVE: TNF alpha inhibitors are usually associated with anthropometric changes over the time, however whether and how the visceral adipose tissue (VAT) is involved in this phenomenon, still remains unclear. Aim of the study is to evaluate if the increases in trunk fat percentage (TF%) and VAT are directly involved in anthropometric changes occurring during treatment, and whether and how a calorie restricted diet could prevent these changes. MATERIAL AND METHODS: Twenty patients receiving TNF-alpha inhibitors for psoriasis was evaluated at baseline (T0) and after 24 weeks of therapy (T24), and then compared with 25 patients receiving a combined treatment based on TNF alpha inhibitors and low-carbohydrates calorie-restricted diet. RESULTS: TNF-alpha inhibitors do not influence the VAT expression. The combined treatment is associated with a significant decrease in body weight (kg) (p < .0001), BMI (p = .0001), WC (cm) (p < .0001), TF% (p < .0001), VAT (p < .0001), serum levels of triglycerides (mg/dL) (p = .0018) and total cholesterol (mg/dL) (p = .0005). CONCLUSIONS: The administration of TNF-alpha inhibitors can induce anthropometric changes after 24 weeks, but it does not cause an increase in VAT. The association between low-carbohydrates calorie-restricted diet and anti-TNF-alpha therapy seems to be able to improve the anthropometric profile of psoriasis patients.

ABSTRACT

BACKGROUND: Actinic keratosis (AK) is a cutaneous intraepithelial neoplasm that typically develops on sun-damaged skin. The incidence of AK is increasing worldwide, and it is accepted as the most frequent pre-malignant lesion in humans. OBJECTIVES: To demonstrate that ingenol mebutate gel is effective in the treatment of actinic keratoses because of its clinical, dermoscopic, capillaroscopic, histopathological and immunohistochemical treatment outcomes. METHODS: Sixty individuals with multiple non-hypertrophic AKs were enrolled into this non-randomized, open-label, prospective, trial. Acquisition of clinical, dermoscopic and capillaroscopic images at baseline (T0), immediately after treatment on 3rd (trunk and/or extremities) or 4th (scalp and/or face) day (T1), 14 days after the end of the treatment (T2) and at 60 days (T3). A subgroup of 20 patients received a cutaneous biopsy both at baseline and at T3 for histological and immunohistochemical evaluation. RESULTS: Clinical improvement was observed in 100% of cases: total clearance in 41 patients (68.3%); partial clearance in 19 patients (32.7%). After treatment, dermoscopic improvement of all non-pigmented and pigmented AK lesions was observed. Most of the dermoscopic features disappeared with treatment. Total disappearance of specific vascular structures or significant reduction in the number and calibre of new blood vessels was capillaroscopically observed in all patients analysed (P ≤ 0.001). The immunohistochemical expression of p63 (P = 0.002), Ki-67 (P = 0.015) and VEGF (P = 0.016) significantly decreased. CONCLUSIONS: The clinical efficacy of ingenol mebutate on AKs is confirmed by its effect on angiogenesis, stem cell activity and cell proliferation in vivo.

ABSTRACT

This review focuses on the emerging concepts concerning the efficacy profile of biological drugs in psoriasis ranging from moderate to severe, and attempts to provide the most recent individual positioning of biologics in treating psoriasis. Biologic agents targeting towards specific immune mediators have emerged as treatment options for patients with moderate to-severe plaque psoriasis unresponsive or intolerant to traditional systemic agents. Data on the safety of biologics are available for up to 5 years in psoriasis and are on the whole reassuring. National registries are still evolving and will provide data on safety, to help the long-term monitoring of patients with psoriasis ongoing biological treatment. Although several biologics have demonstrated good efficacy and tolerability in short-term trials, treatment guidelines recommend them as third line therapies due to relative lack of long-term safety data, especially for those who have been commercialized recently. Here, we have reviewed the long-term safety data obtained from National Registries, randomized controlled trials, open-label extension studies and meta-analyses on etanercept, infliximab, adalimumab, and ustekinumab in the treatment of adults with moderate to severe plaque psoriasis.

ABSTRACT

BACKGROUND: People with psoriasis are at higher cardiovascular risk. Plasma levels of homocysteine over the normal range have been recognized as marker of cardiovascular risk. Psoriasis patients express higher levels of plasma homocysteine than healthy people. OBJECTIVE: Our study aims to investigate the correlation between homocysteinaemia, severity and duration of psoriasis and psoriasis arthritis, and to evaluate the effect of a 12-week administration of a target therapy for psoriasis on homocysteinaemia. METHODS: Fifty-two psoriasis patients (study group) submitted to different kind of therapy for psoriasis (biological, systemic not biological and topical) and 24 healthy Italian subject (control group) were evaluated for their plasmatic homocysteine levels, both at baseline (T0) and 12 weeks after they a specific therapy for psoriasis. RESULTS: A significant difference between the homocysteinaemia of psoriasis patients (mean 19.71 ± 11.16) and control group (13.90 ± 11.18), P < 0.05 (Fig. 1), was found at baseline (T0). The mean plasma levels of homocysteine were directly correlated with disease severity (P = 0.0401), but not with disease duration (P = 0.6018) or presence of arthritis (P = 0.6221) at baseline. None among the treatments administered to psoriasis patients caused a significant reduction in homocysteinaemia after 12 weeks of treatment. CONCLUSION: Our results confirm that psoriasis patients with more severe disease, can have hyperhomocysteinaemia, without regard to disease duration or joint involvement. Hyperhomocysteinaemia is not influenced by a target therapy for psoriasis and it is as greater as psoriasis severity. However, limitation of our study is the relatively small number of cases. Homocysteine plasmatic levels should be advisable as a further independent risk factor for cardiovascular disease in psoriasis patients.

ABSTRACT

Poor data regarding skin involvement in Myotonic Dystrophy, also named Dystrophia Myotonica type 1, have been reported. This study aimed to investigate the prevalence and types of skin disorders in adult patients with Myotonic Dystrophy type 1. Fifty-five patients and one hundred age- and sex-matched healthy subjects were referred to a trained dermatologist for a complete skin examination to check for potential cutaneous hallmarks of disease. No difference in prevalence of preneoplastic, neoplastic, and cutaneous lesions was detected between the two groups. Among morphofunctional, proliferative and inflammatory lesions, focal hyperhidrosis (p < 0.0001), follicular hyperkeratosis (p = 0.0003), early androgenic alopecia (p = 0.01), nail pitting (p = 0.003), pedunculus fibromas (p = 0. 01), twisted hair (p = 0.01), seborrheic dermatitis (p = 0.02), macules of hyperpigmentation (p = 0.03) were significantly more frequent in patients compared with controls. In patients with Myotonic Dystrophy type 1 significant differences according to sex were found for: early androgenic alopecia, twisted hair and seborrheic dermatitis, whose prevalence was higher in males (p < 0.0001). Our preliminary results seem to rule out an increased prevalence of pre-neoplastic, and neoplastic skin lesions in Myotonic Dystrophy type 1. On the other hand, an increased prevalence of morphofunctional, inflammatory, and proliferative diseases involving adnexal structures seems to characterize adult patients with Myotonic Dystrophy type 1.

ABSTRACT

Toxic epidermal necrolysis (TEN), also known as Lyell syndrome, is a potential life-threatening muco-cutaneous disease with important systemic implications. It affects the skin and mucous membranes, with involvement of more than 30% of body surface and it is mostly caused by drugs. Although the pathogenesis is not fully elucidated, it is probably linked to the inability to detoxicate reactive metabolites of drugs, to genetic susceptibility and to immune factors leading to cellular apoptosis. Currently, there are no randomized control trials and stardardized therapeutical approaches for the management of Lyell syndrome; therefore controversial clinical responses to the most common used drug in TEN make it difficult for the clinical-therapeutic approach. The authors reported their experience on three patients affected by Lyell syndrome treated with infliximab.

ABSTRACT

The ocular involvement in psoriasis is not a completely well-known problem. The ophthalmologic involvement occurs in about 10 % of patients, particularly in case of arthropathic or pustular psoriasis. Ocular lesions are more common in males, and they often occur during psoriasis exacerbations. Our study aimed to assess the prevalence and type of ocular involvement in psoriasis, by a comparison between psoriasis and healthy subjects, and if/how a 12-week long systemic immunosuppressive therapy is able to modify them. This study involved thirty-two psoriatic patients and thirty-two healthy subjects. Dermatological evaluation was done using Psoriasis Area and Severity Index, Physician Global Assessment, and Dermatology Life Quality Index (PASI, PGA, and DLQI score). Ophthalmological evaluation included ocular surface involvement (Schirmer, Jones, break-up time--BUT, DR-1 camera), retinal pathologies, and ocular surface disease index. Laboratory investigations including the C-reactive protein (CRP) of all the patients were performed. At baseline, the values of Schirmer, Jones, and BUT tests in the patient group were significantly lower compared to controls; moreover, conjunctival hyperemia was more frequent in psoriatic patients than in healthy subjects. Ocular involvement was more prominent in the subset of psoriatic patients with sebo-psoriasis than in general psoriatic population. A statistically significant correlation was found in sebo-psoriasis between PASI and Schirmer, between PASI and Jones, and between PASI and BUT. On the other hand, the results obtained from DR1 camera showed statistically significant difference between psoriatic and sebo-psoriatic patients at the end of the follow-up. After 12 weeks of treatment, the mean values of PASI, PGA, DLQI, CRP, and BUT showed significant changes in psoriatic patients. Our findings suggest a high rate of ocular involvement in psoriatic patients, emphasizing the need of performing periodic ophthalmological examinations in order to avoid underestimating eye diseases and to allow early diagnosis and treatment of patients.

ABSTRACT

Treatment of multiple cutaneous and subcutaneous melanoma metastases is still represents a therapeutic challenge for both dermatologists and oncologists. Electrochemotherapy (ECT) is a promising therapeutic procedure, owing to its ability to improve the penetration of cytotoxic drugs into cancer cells by application of current electric pulses. The aim of our study is to evaluate efficacy, tolerability and long-term efficacy of ECT in the treatment of advanced metastatic melanoma. Thirty patients affected by a total of 654 cutaneous and subcutaneous melanoma metastatic nodules were recruited. All patients were treated after they had undergone to a mild general anesthesia. Intravenous Bleomicina solution was administered 8 minutes before the application of electric pulses, generated by a Cliniporator (TM) (the device validated for ECT). The objective response rate of 100% (67.28% complete response and 32.72% partial response) was observed. A total of 214 metastatic lesions from 24 patients received a second ECT session, among them 141 showed a further complete response. Twenty-four months later, the local tumor control rate was 72%. The results of this study seem to demonstrate that ECT is an effective and valid therapeutic tool for the treatment of cutaneous metastases from melanoma. ECT can be considered a first-line palliative treatment since it is able to alleviate pain and reduce the tumor's spontaneous bleeding with a significant improve of patients' quality of life.

ABSTRACT

Focal hyperhidrosis often has a substantial psychological and social impact on quality of life, since it interferes with daily activities. To date, for the treatment of focal hyperhidrosis, the botulinum toxin type A is an effective second line tool. The purpose of this study was to compare Onabotulinumtoxin A (Botox(®)) and Incobotulinumtoxin A (Xeomin(®)) administration in the treatment of palmar hyperhidrosis. In a double-blind clinical trial, 25 patients with moderate or severe palmar hyperhidrosis received in the same session intradermal injections of Onabotulinumtoxin A on one hand and Incobotulinumtoxin A on the other. Several measures of efficacy and safety were evaluated: disease severity improvement, sweat reduction, hand-grip strength decrease, pain/discomfort during the treatment, and patient's global satisfaction. All patients were responsive to the treatments (HDSS at T4 vs HDDs at T0; p < 0.0001), and no significant difference between Onabotulinumtoxin A and Incobotulinumtoxin A in terms of anhidrotic effect (Minor's test at T4; p = 0.51), long-term efficacy (Minor's test at T12; p = 0.76), (Minor's test at T24; p = 0.58), subjective pain related to the injections (p = 0.88), muscle strength reduction after treatment (p = 0.56), and global satisfaction with the treatment (p = 0.26). Onabotulinum toxin A and Incobotulinumtoxin A seem to be comparable in terms of anhidrotic effect (short-term results), duration of benefits (long-term efficacy), muscle strength reduction (safety), pain related to injections (tolerability), and treatment satisfaction expressed by patients.

ABSTRACT

Botulinum toxin type A (BoNT/A) improves symptoms of palmar hyperhidrosis, but some drawbacks related to its injection in the hands still persist (e.g., muscle weakness caused by drug diffusion, pain during injections, or delayed functional recovery of the hand when using wrist block). In this open, controlled, non-randomized, intra-individual clinical trial, 50 patients with severe palmar hyperhidrosis received in the same session intradermal injections of BoNT/A through a new injection technique (NA/BoNT/A) based on the use of a specific adapter for needles (PCT/IT2011/000299) in one hand, and BoNT/A injection following the anaesthetic block of the wrist (WB/BoNT/A) in the other. Several measures of efficacy and safety were evaluated both before (T0) and four weeks after the treatment (T4): disease severity improvement, sweat reduction, handgrip strength decrease, pain/discomfort during the treatment, and patient's global satisfaction. All patients were also re-evaluated through the gravimetric assessment of sweat production in both hands at T12 and T24 to compare the long-term efficacy of the two treatments. All patients were responsive to the treatments, and disease severity was significantly decreased at T4 compared to baseline (p < 0.0001). Both procedures were equally effective in reducing sweat production in the short term (p = 0.08 at T4), but WB/BoNT/A caused a higher decrease of handgrip strength compared with WB/BoNT/A at T4 (p < 0.0001). Finally, patients reported that NA/BoNT/A and WB/BoNT/A procedures were comparable for pain/discomfort (p = 0.204); however, they were globally more satisfied with the NA/BoNT/A rather than WB/BoNT/A method (p < 0.0001). No significant difference in percentage of clinical relapse at T12 and T24 was detected between hands treated via WB/BoNT/A or NA/BoNT/A (p = 0.70). The use of the described adapter to inject BoNT/A in the hands seems to lead the clinicians to obtain same therapeutic results of conventional method based on the use of anaesthetic block of the wrist. Moreover, this new injective approach seems to increase the safety of the treatment by reducing the extent of muscle weakness and is preferred by patients mostly because it makes the functional recovery of the hand faster.

ABSTRACT

INTRODUCTION AND AIM: Several studies have demonstrated that ozonated oil is effective on cutaneous wound healing. This in vivo study has been conducted to evaluate the clinical effect of the topical application of ozonated oil for 12 weeks on second-degree skin burns. METHOD: A total of 30 patients suffering from second-degree skin burns in the phase of re-epithelisation were included in this study. Every skin burn was subdivided in two symmetrical parts. One part was treated with occlusive application of ozonated oil; the contralateral part of the lesion was treated with topical application of hyaluronic acid gel, once a day for 12 weeks. A clinical evaluation and an intra-vital video-capillaroscopy were performed on every patient at baseline, 6 and 12 weeks after. RESULTS: All treated lesions improved regardless of the treatment used. Ozonated oil was as effective as hyaluronic acid in improving erythema, tension, itching and burning sensation reported by patients, and it does not exert a specific anti-angiogenic effect compared to hyaluronic acid. However it seems more effective than hyaluronic acid in reducing post-lesional hyperpigmentation. CONCLUSION: Ozonated oil, topically applied for 12 weeks, seems to be as effective as hyaluronic acid in reducing symptoms related to skin burns, but it could be more effective in preventing the post-lesional hyperpigmentation.

ABSTRACT

Acne agminata is a rare asymptomatic, inflammatory dermatosis, which affects adolescence and young adults, whose etiopathogenesis is already controversial. Clinically, acne agminata is characterized by red-yellow-brown papular-pustular eruption involving the central face, in particular cheeks, chin, forehead, and eyelids. The authors report a case of a 25-year-old Caucasian man affected by acne agminata treated with doxycycline and isoniazid.

ABSTRACT

BACKGROUND: No material about the identification of predictive clinical factors of therapeutic response to Botulinum Toxin Type A (BTX-A) in focal idiopathic hyperhidrosis has been found. OBJECTIVE: To evaluate if age, sex, extension rate of hyperhidrotic area, localization, disease-related impairment of life quality, number of previous local, non-invasive treatments different from BTX-A, and duration of disease, may affect the relapse-free survival (RFS) after a BTX-A treatment in palmar and axillary focal idiopathic hyperhidrosis. METHODS: Forty-one patients suffering from palmar hyperhidrosis, and 38 patients suffering from axillary hyperhidrosis received intradermal injections of BTX-A. All patients were clinically screened before and after treatment; they were followed for 15 months after it, according to Hyperhidrosis Disease Severity Scale (HDSS), Minor's test, and DLQI test, to state disease severity, and disease-related impairment of quality of life. RESULTS: The duration of therapeutic effect of BTX-A is not significantly influenced by age (P = 0.783), sex (P = 0.762), extension of hyperhidrotic area (P = 0.770), site of involvement (P = 0.402), disease-induced impairment of life quality (P = 0.745), number of previous therapies (P = 0.730), or site of involvement (P = 0.402). In palmar idiopathic hyperhidrosis, patients with a longer disease history show a shorter duration of RFS after a treatment with BTX-A (P = 0.01). CONCLUSIONS: Patients suffering from palmar hyperhidrosis have a longer lasting disease, and a length of disease more than 20 years in these patients influences the RFS after BTX-A treatment.

ABSTRACT

Alopecia areata (AA) is an inflammatory skin disease the most effective therapy for which is diphenylcyclopropenone (DPCP). Videodermatoscopy and intra-vital capillaroscopy (IVCP) are two non-invasive techniques that help in the differential diagnosis of alopecias. It is known that, after DPCP therapy, there is a histologically proven significant increase of VEGF in hair follicle keratinocytes and a consequent increase in capillary vessels in the dermis of the same follicles. The aim of our study is to emphasize any clinical and videodermatoscopic-videocapillaroscopic changes after DPCP treatment in 20 patients affected by alopecia areata. Videodermatoscopic images and an intravital videocapillaroscopic analysis were performed at T0, T12 and T24 to emphasize clinical modifications and microscopic changes in vascular pattern before and after DPCP treatment. At T0, videodermatoscopy showed the presence of exclamation point hairs, hair follicles filled with hyperkeratotic plugs (yellow dots), hair follicles containing cadaverized hairs (black dots) and broken hairs. IVCP highlighted a pale scalp, and vessels were not visible. At 24 weeks (T24), videodermatoscopy revealed the disappearance or a statistically significant reduction of AA hallmarks and an increase of number of vellus hairs. Videocapillaroscopy showed a statistically significant increase of new vessels and, where neoangiogenesis were more marked, a major hair regrowth was evident. Our study emphasizes that, after DPCP therapy, neoangiogenesis is detectable by videocapillaroscopy and these new capillaries could be considered an initial positive attempt to compensate capillary loss of T0 alopecia areata images.

ABSTRACT

Several studies suggest that microangiopathy plays a crucial role in the pathogenesis of psoriasis. TNFalpha up-regulates the genetic transcription of VEGF, a pro-angiogenetic cytokine over-expressed in psoriatic skin, which promotes micrangiopathic modifications in psoriatic plaque. Etanercept is a chimeric protein used in the treatment of psoriasis and other immunomediated disorders, which blocks inflammatory response by interfering in the binding of TNF-alpha to its receptors. Starting from this data, we retain that etanercept can improve microangiopathy in psoriatic skin by reducing the synthesis of pro-angiogenetic chemokine VEGF. The aims of the study are: to verify the effect of etanercept on cutaneous en plaque capillaries in vivo using intra-vital videocapillaroscopy analysis, to evaluate the relation between the en plaque videocapillaroscopic pattern and the immunohistochemical cutaneous expression of VEGF in psoriasis, and finally to correlate all these in data with clinical disease activity. Eighteen patients (10 male and 8 female, mean age 51, range 21-60) suffering from stable, en plaque type psoriasis, involving at least 10 percent of body surface area (BSA), and not responsive to conventional therapy were included in the study. All the enrolled patients received etanercept 50mg/twice/week, subcutaneously, for 12 weeks, and were carefully followed up for clinical response with PASI score and DLQI index both before (T0) and after 12 weeks (T12) of treatment with etanercept. A well demarcated psoriatic plaque of the extensor surface of upper extremities was chosen to perform an intra-vital videocapillaroscopy analysis (IVCP), and a skin biopsy for immunohistochemical study both at T0 and T12 in all the included patients, in order to evaluate the presence of microangiopathy and its modification after therapy. All the patients experienced a clinical improvement of cutaneous disease with a significant decrease of PASI score (p<0.0001) and DLQI level (p<0.0001), throughout the twelve weeks of treatment. On IVCP analysis, microangiopathy dramatically decreased (p<0.0001), this modification being significantly related with PASI and DLQI decrease at T12. Immunohistochemical expression of VEGF decreased significantly from T0 to T12 (p<0.0001), and was related with a reduction of psoriatic microangiopathy at T12. The results of our videocapillaroscopic and immunohistochemical investigation confirm that the therapeutic potentiality of etanercept is based also on its capability to promote the regression of psoriatic microangiopathy. Moreover, according to these considerations, videocapillaroscopic evaluation of psoriatic plaque, both before and after treatment with etancercept, may be a useful tool to objectively demonstrate its effect on microcirculation.
