Tratamento com inibidores do tnf-alfa em doentes com infecção prévia por vírus ...

Estima-se que cerca de 2 mil milhões de pessoas estejam infectados pelo vírus da hepatite B (VHB) e que mais de 350 milhões sejam portadores crónicos. Os doentes que apresentam anticorpos para o antigénio core (Ac anti-HBc) com negatividade para antigénio de superfície (AgHBs), não têm hepatite crónica, mas contactaram com o vírus no passado. Este estado serológico corresponde, na maioria das vezes, a uma elimi...

IL-6 and TNF-alpha polymorphisms in portuguese psoriatic patients

Introduction: Cytokines regulate the growth, function and differentiation of cells and help to steer immune response and inflammation. In this study we focused our attention in two proinflammatory cytokines: IL-6 and TNFa. It is known that their overexpression is responsible for initiation, maintenance and recurrence of skin lesions in psoriatic patients. Therefore, it is important to investigate genetic biomar...

Apoe isoforms in patients with psoriasis

Introduction: Psoriasis is a chronic inflammatory skin disease affecting 2–3% of the world population. Patients with psoriasis (Ps) have higher prevalence of lipid disorders when compared to unaffected individuals. These patients, especially those with severe and prolonged disease, have an increased morbidity and mortality from cardiovascular events. Apolipoprotein E (ApoE), a protein involved in lipid metaboli...

Psoríase e Doença Cardiovascular

A psoríase é uma doença inflamatória sistémica crónica, frequente, associada a várias comorbilidades, destacando-se a obesidade, a hipertensão arterial, a diabetes, a dislipidemia e síndrome metabólico. Adicionalmente associa-se também a aumento do risco de doença cardiovascular – enfarte agudo do miocárdio e acidente vascular cerebral. A inflamação sistémica crónica presente na psoríase tem sido sugerida como ...

Impact of Biosimilars in Psoriasis Treatment

Effectiveness of Aprepitant in Patients with Refractory Pruritus Secondary to S...

Background: In advanced stages, patients with Sézary Syndrome (SS) commonly report an ill-defined, severe and diffuse pruritus. Recently, it has been reported that Aprepitant, an oral neurokinin-1-receptor (NK1) antagonist, may have an important role in relief of refractory pruritus in patients with SS. Material and methods: A prospective study which included four patients with SS, in whom pruritus is the main ...

Tratamento da psoríase com agentes biológicos: para além dos inibidores do tnf ...

A psoríase é uma doença inflamatória crónica multissistémica, mediada por células T, com elevado grau de morbilidade. A investigação na área da psoríase tem sido intensa, resultando num conhecimento mais porme- norizado da sua patogenia, e consequente desenvolvimento de novas terapêuticas biológicas. Esta revisão focará o presente e o futuro dos agentes biológicos moduladores de citoquinas que não pertencem à c...

Foscarnet-induced penile ulceration

Foscarnet is used to treat infections with herpes viruses, including drug-resistant cytomegalovirus (CMV) and infections with herpes viruses 1 and 2 (HSV-1 and HSV-2). There are some reports of intravenous foscarnet-induced penile and vulvar ulceration. The authors report a case of severe penile ulcers after the initiation of intravenous foscarnet therapy

Photodynamic therapy as adjunctive therapy for morpheaform basal cell carcinoma

The authors decided to evaluate the possible use of methyl-aminolevulinate photodynamic therapy (MAL-PDT) as adjunctive therapy for morpheaform basal cell carcinoma prior to standard surgical excision in order to reduce tumor size and volume and to facilitate surgical treatment. It was observed that MAL-PDT may be an option as an adjunctive therapy prior to standard surgical excision of morpheaform basal cell c...

Penile Kaposi sarcoma: A case of complete resolution with highly active antiret...

Kaposi sarcoma remains an important cause of morbidity in HIV-infected patients. Regardless of the recent pharmacological progress, treatment of this malignancy is still disappointing. We report the case of a patient with Kaposi sarcoma in an unusual localization, the penis, which completely resolved with highly active antiretroviral therapy alone
