RESUMO

BACKGROUND: Cyclosporine A (CsA) is one of the systemic therapeutic options for moderate-to-severe psoriasis, based on its efficacy and rapidity of action. The current study investigated the response to CsA in patients with moderate-to-severe plaque psoriasis. MATERIALS AND METHODS: TRANSITION was an observational, cross-sectional, multicentre study which evaluated the proportion of partial- and suboptimal-responders among patients with moderate-to-severe plaque psoriasis treated with continuous CsA for ≥12 weeks. Patients demonstrating a Psoriasis Area and Severity Index (PASI) response of ≥90, ≥75 and <90, ≥50 and <75 and <50 were defined as responders, suboptimal-responders, partial-responders, and non-responders, respectively. RESULTS: A total of 196 patients (mean age, 46.6 years; 62.8% males) from 14 sites in Italy were evaluated. At the study visit, the mean (SD) PASI score was 4.2(5.5) compared with 15.3(7.1) prior to the last CsA cycle. For response categories, 39.8%, 22.4%, 16.8%, and 20.9% of patients were responders, suboptimal-responders, partial-responders, and non-responders to CsA treatment. Overall, 28.6% of patients permanently discontinued treatment with CsA (lack of efficacy [10.2%], poor tolerability and voluntary discontinuation [3.6% each], and other [11.7%]). CONCLUSION: Patients were only partially satisfied with CsA treatment, reporting measurable impact on quality of life. Only 40% patients showed a satisfactory response to CsA.

RESUMO

BACKGROUND: The anti-tumour necrosis factor (TNF)-α adalimumab is the only licenced biologic for moderate-to-severe hidradenitis suppurativa (HS). No predictors of response have been identified so far. OBJECTIVES: To identify clinical parameters predicting response to adalimumab and confirm its efficacy/safety. METHODS: The data of 389 patients with HS treated with adalimumab in 21 Italian centres were reviewed. Sex, age at onset/diagnosis/baseline, body mass index, smoking, phenotype, previous treatments, concomitant antibiotics and 'therapeutic delay', defined as the time from HS onset to adalimumab initiation, were assessed. Response to adalimumab and its impact on quality of life (QoL) were evaluated using the Hidradenitis Suppurativa Clinical Response (HiSCR) and the Dermatology Life Quality Index (DLQI) or the Visual Analogue Scale for pain (VAS pain), respectively. Logistic regression analysis was performed. RESULTS: The therapeutic delay correlated to lack of response to adalimumab at week 16 [odds ratio (OR) 1·92 for therapeutic delay > 10 years; 95% confidence interval (CI) 1·28-2·89; P = 0·0016). HiSCR was achieved in 43·7% and 53·9% patients at week 16 and 52, respectively. Significant reductions in both DLQI and VAS pain were found between week 16 vs. baseline (P < 0·0001 for both) and week 52 vs. baseline (P < 0·0001 for both). Previous immunosuppressants inversely correlated to HiSCR at week 52 (OR = 1·74, 95% CI 1·04-2·91, P = 0·0342). CONCLUSIONS: Inverse correlation between therapeutic delay and clinical response was found, supporting early adalimumab use and providing evidence for a 'window of opportunity' in HS treatment. Adalimumab efficacy and safety were confirmed, along with patients' QoL improvement. Immunosuppressants could negatively influence the response to adalimumab inducing a switch to non-TNF-α-driven pathways.

RESUMO

Psoriasis is a chronic inflammatory skin disease affecting 2-3% of the population in the world. The scalp is the most common, and frequently the first site of disease involvement. Occasionally it may be the only localization of psoriasis. Treatment of scalp psoriasis is often unsatisfactory, due to limited available topical therapy and reduced efficacy of some systemic drugs. Biologic therapies are recommended for severe psoriasis, resistant to topical treatment, but evidence from randomized, controlled studies is lacking regarding effectiveness on scalp-localized lesions. Several clinical studies have shown the efficacy of secukinumab on plaque psoriasis, and some encouraging experience suggest the use in difficult sites such as the scalp; this article reports effective treatment with secukinumab of a series of patients with plaque and scalp psoriasis.

RESUMO

Adverse drug reactions to highly antiretroviral therapy (HAART) are major obstacles in its success. Although overall mortality from HIV has dramatically declined owing to HAART, these antiretroviral regimens have been associated with a wide spectrum of severe cutaneous reactions. The severity of cutaneous adverse reactions varies greatly, and some may be difficult to manage. To optimize adherence and efficacy of antiretroviral treatment, clinicians must focus on preventing adverse effects whenever possible, and distinguish those that are self-limited from those that are potentially serious. This paper presents the case of a serious cutaneous adverse reaction to Atripla in a HIV-positive 50-year-old Caucasian woman.

RESUMO

BACKGROUND: Psoriatic arthropathy is a progressive and debilitating disease involving reduction of functional activity of the articulations with consequent deterioration of the patient's quality of life. The entheses represent the initial site of articular inflammation and the enthesis of the Achilles tendon is the first to be affected. In some patients with psoriasis, enthesitis may not be diagnosed because it is still asymptomatic. OBJECTIVES: To evaluate whether ultrasonography allows early diagnosis in a larger population and to identify significant alterations of enthesitis beyond increased thickness of the Achilles tendon. MATERIALS AND METHODS: The study was undertaken on 59 patients (16 women, 43 men), with chronic plaque psoriasis and 59 patients with other dermopathies. The patients underwent echographic evaluation of the Achilles heel using a Voluson imaging system. The severity of the psoriasis was evaluated by the Psoriasis Area Severity Index and the enthesitis by the Glasgow Ultrasound Enthesitis Scoring System (GUESS). RESULTS: The GUESS score was higher in those patients with psoriasis compared with patients with other dermopathies. Among psoriatic patients, 22% (13 of 59) presented tendon thickness over 5·29 mm and irregular tendon structure. Other abnormalities affected the tendon in 12 patients. In seven patients (12%) bursitis was also revealed. CONCLUSIONS: Our data confirm that ultrasonography is a sensitive technique which reveals enthesitis more frequently than clinical examination in patients affected by psoriasis. We suggest the use of ultrasonography of the Achilles tendon in early diagnosis of psoriatic arthropathy with the objective of preventing progression of the pathology.

RESUMO

We report a case of multiple cutaneous metastases from prostate cancer. A 78-year-old man with an 8-year history of prostate cancer had multiple nodular lesions in the chest. Histologically, the lesion showed an abortive glandular lumina and tall columnar cells with abundant cytoplasm. Immunohistochemical staining for AE1:AE3 cytokeratin cocktail, prostate-specific antigen, and prostate-specific acid phosphatase was positive in tumor cells, confirming the diagnosis of cutaneous metastases from prostate cancer. We report this case because of the rarity of cutaneous metastases from prostatic adenocarcinoma in the chest region.

RESUMO

Isolated angiokeratomas are common benign cutaneous lesions, generally deemed unworthy of further investigation. In contrast, diffuse angiokeratomas should alert the physician to a possible diagnosis of Fabry disease, a rare X-linked lysosomal storage disorder, characterized by α-galactosidase deficiency. Glycosphingolipids accumulate in cells throughout the body resulting in progressive multi-organ failure. Difficulties are encountered when trying to interpret the significance of angiokeratomas because they may also occur in other lysosomal storage disorders and rarely in an isolated manner in Fabry disease. We present an algorithm for the classification of angiokeratomas which might prove useful for the diagnosis and management of Fabry disease. Assessment of the clinical features and location of the lesions, personal and family history, skin biopsy, dermoscopy and electron microscopy imaging are sequential steps in the diagnostic process. Assessing the deficiency of α-galactosidase enzyme activity is essential to confirm the diagnosis in males, while mutation analysis is always needed in females. Potentially this algorithm can change the current approach to patients when Fabry disease is suspected, thus improving the diagnostic strategy and management of this disorder. It remains to be decided whether the use of an algorithm might reduce the number of genetic consultations. As evidence has shown the efficacy of enzyme replacement therapy in halting progression of the disease before the onset of irreversible organ damage, it is advisable to aim at an early diagnosis in order to achieve timely initiation of effective treatment with benefits for patients and appropriate use of medical resources.

RESUMO

Matrix metalloproteinases (MMPs) are associated with Kaposi's sarcoma (KS) tumorigenesis and may contribute to the mechanism of KS invasive growth. To date, only a few MMPs have been studied in KS lesions, and exactly which MMPs are involved in KS development and progression remains unanswered. However, MMPs 2 and 9 have been associated with different phases of angiogenesis, but their role in the proteolytic modification of the extracellular matrix has not been investigated. The results of this study confirm that MMPs, specifically MMP-2 and MMP-9, can contribute to angiogenesis by disrupting the vessel basement membrane and other extracellular matrix barriers, and enabling endothelial cells migration through the surrounding tissues.

RESUMO

Mycosis fungoides (MF) is an uncommon primary cutaneous lymphoma with a wide spectrum of clinicopathological manifestations. Diagnosis can be difficult in its early stages given the considerable overlap with more common benign dermatoses. We report an unusual case of MF in a 52-year-old male presenting with psoriasiform plaques on the palms and the soles who rapidly developed additional lesions on the scalp, limps and trunk. Punch biopsy of the face was obtained for routine histology and immunohistochemical stains. Chest X-ray, total body computed tomography scanning and excisional biopsy of the inguinal lymph node were performed. Review of the face biopsy revealed a diffuse dermal infiltrate containing a high number of atypical lymphocytes showing a CD3+, CD4+, CD45RO+, CD8-, CD20- immunophenotype and epidermotropism. Findings were consistent with tumor stage MF (stage IIB, T3 N1 M0). We report a rare presentation of MF mimicking psoriasis vulgaris.

RESUMO

Psoriasis and psoriatic arthritis are common diseases associated with considerable morbidity and disability. Their pathophysiology comprises similar processes leading to inflammation of skin, entheses, and joints. Although traditional systemic agents can be effective, their use may be limited by lack of efficacy and concerns regarding adverse effects. The objective of this study was to assess the efficacy and safety of adalimumab, a fully human antitumor necrosis factor (anti-TNF) monoclonal antibody, over 16 weeks. The present authors report their personal experience in 15 patients with severe plaque psoriasis and psoriatic arthritis, refractory to other treatments, in which a decisive regression of joint/skin involvement was obtained. Psoriasis and psoriatic arthritis are chronic inflammatory disorders resulting from a combination of genetic and environmental factors.

RESUMO

The present authors reported a 14-year-old white boy who visited the present authors' dermatology department in January 2004. Physical examination revealed multiple translucent and hemorrhagic vesicles and skin-colored nodules on the chin. The lesion had grown slowly in size over the previous 7 years. The objective of this study is to estimate the exact mechanism of action of topical imiquimod on mixed capillary/lymphatic malformation. After 4 weeks of therapy the lesions were less protuberant. At the follow-up examination after a further 2 months of therapy, there was partial clinical regression of the capillary component with a return to normal skin color. One month after termination of therapy the lesions had completely regressed and there was no evidence of recurrence of the hemangiomatous section. The present authors' case suggests the efficacy of the use of topical imiquimod and this therapeutic modality may be of particular benefit in superficial type of capillary/lymphatic malformation, in which the destructive intervention may be undesirable.
