The behaviour of extracellular matrix glycoproteins (fibronectin, laminin, basement membrane heparan-sulphate proteoglycan, type III, IV and V collagens) has been investigated in a sequential model of experimental hepatic fibrosis, using an immunofluorescence technique. The presence of some basement membrane macromolecules (such as type IV and V collagens,(More)
Vitiligo is a skin disorder characterized by loss of functional melanocytes. Keratinocytes contribute to melanocyte homeostasis, and keratinocyte alteration may play a role in melanocyte dysfunction in vitiligo. In particular, the release of melanogenic mediators and the level of functioning keratinocytes may affect melanocyte dysfunction in vitiligo(More)
Pemphigoid gestationis (PG) is a rare dermal-epidermal autoimmune bullous disease of pregnancy and postpartum, which relapses more seriously and earlier during following pregnancies. PG also occurs in association with trophoblastic tumours or oral contraceptive treatment. The term 'persistent PG' represents the cases where active disease persists for months(More)
We describe a 5-year-old boy with red-pink, firm, nodular lesions, with central resolution and prominent borders, localized to the face, backs of the hands, extensor surfaces of the arms and legs, and the buttocks. He also had recurrent bacterial respiratory infections. Quantitative immunoglobulin levels revealed hypogammaglobulinemia and increased IgM(More)
BACKGROUND A recent systematic evaluation of vitiligo and psoriasis comorbidity has not yet been reported in a large series of patients with vitiligo. OBJECTIVE To investigate the practical/clinical implications in subjects with both vitiligo and psoriasis compared to those with vitiligo alone. METHODS This was a case-control study on 463 vitiligo(More)
Current treatments for vitiligo are largely unsatisfactory. Topical corticosteroids and phototherapy (narrow-band UVB and psoralen+UVA) are the most prescribed, however, these therapies are often not effective and have important side-effect, especially when used for a long time. Many studies have reported the efficacy and safety of tacrolimus ointment in(More)
Three cases of adult, non-segmental vitiligo patients in which primary, common variable immunodeficiency (CVID) was present are described. In two of the three cases, psoriasis was also present. Onset of CVID was diagnosed before vitiligo in two patients, and subsequent to the onset of vitiligo in the remaining patient. A family history of CVID was negative(More)
