<p>Bullous pemhigoid (BP) is an autoimmune subepidermal blistering&nbsp;disease, usually occurring in the elderly. In Europe the incidence of BP has doubled in the last 10 years. The disease&nbsp;has a chronic relapsing course and a relatively benign prognosis. An increasing number of publications report altered&nbsp;expression of a number of cytokines. However, at the present it is not possible to establish a specific role for them in&nbsp;the disease. We report a case of a centenarian woman with a BP occurrence in otherwise optimal health conditions.&nbsp;Besides the usual biochemical investigations, plasma concentrations of a number of cytokines were evaluated during&nbsp;the disease course (relapse and remission). The majority of the measured cytokines were elevated in the active phase&nbsp;of the disease and returned to values similar to those presented by a group of apparently healthy subjects of similar&nbsp;age during the remission. This case could be useful to better understand the role of cytokines in autoimmune skin&nbsp;diseases of the aging.</p>

Interleuchine e necrolisi tossica epidermica
Interleukins and toxic epidermal necrolysis (TEN)

<p>TEN is a rare disease characterized by the separation of skin&nbsp;and mucous membranes from the derma. The reported clinical case refers to an adult female hospitalized at the&nbsp;Burns Unit after allopurinol prescription. During hospitalization the patient underwent the therapeutic protocol&nbsp;established at the Burns Unit including intravenus immunoglobulin administration and plasmapheresis. At the end of&nbsp;therapy a clinical improvement of both local and global conditions was observed. During the course of disease, we&nbsp;measured plasma concentrations of a number of cytokines. Measurements were performed using commercially&nbsp;available multiplex bead-based sandwich immunoassays (Biorad). We found a marked decrease in concentrations of&nbsp;interleukin (IL)-6, interferon -induced protein (IP)-10 e IL-13 at various stages of apheresis therapy, particularly&nbsp;pronounced for IP-10. We also found a normalization of IL-6 and IP-10 concentrations during the follow-up. In&nbsp;addition, very high concentrations of the same cytokines in the plasma effluent after apheresis were observed.&nbsp;Although obtained in a single case, our results suggest a correlation between plasma concentrations of cytokines and&nbsp;the clinical course of TEN. It can be postulated that this approach could serve as a guide for future research in the&nbsp;development of targeted therapy based on the etiopathogenesis of TEN.</p>

Polimorfismo I/D del gene per l’enzima di conversione dell’angiotensina (ACE): gene della longevità o fattore di rischio nella patologia ipertensiva?
Polymorphism of the angiotensin converting enzyme gene: longevity gene or risk factor in hypertensive disease?
<p>In recent decades, the increase in life expectancy stimulated the study of aging processes and the search for&nbsp;candidate genes involved in longevity. The angiotensin converting enzyme (ACE), present in all endothelial cells, plays&nbsp;an essential role in maintaining the homeostasis of blood flow by regulating the production of the vasoconstrictor&nbsp;angiotensin II and inactivating the bradykinin. Some studies reported a possible association between the polymorphism&nbsp;I/D of ACE gene and either hypertension and longevity. The present study was aimed to confirm these data. We studied&nbsp;two large cohorts of nonagenarians and centenarians. One was from Sardinia (200 subjects, 88 males, mean age: 96&nbsp;years) and their data were compared to a group of 222 subjects (106 males, mean age: 44 years) from the general&nbsp;population of the same geographic area. The latter group of longeve subjects (161 subjects, 71 males, mean age: 97&nbsp;years) was from Southern Italy. Furthermore, we studied 146 hypertensive patients (98 males, mean age: 51 years) and&nbsp;172 normotensive subjects (86 males, mean age: 33 years) from Southern Italy. The ACE I/D polymorphism was typed&nbsp;by polymerase chain reaction; the amplified 490 bp (allele I) and 190 bp (allele D) were visualized on 2% agarose gel.&nbsp;Hypertensive subjects had a significantly different distribution of ACE genotypes as compared to normotensive ones&nbsp;(P=0.001) and a higher frequency of the D/D genotype. Long-lived subjects from Sardinia showed a significantly different&nbsp;distribution of ACE genotypes as compared to subjects from the general population of the same geographic area (P&nbsp;&lt;0.001), to long-lived subjects from Southern Italy (P &lt;0.001), to hypertensive patients (P=0.011) and to normotensive&nbsp;subjects from Southern Italy (P &lt;0.001). Surprisingly, they had the highest frequency of the D/D genotype among the&nbsp;compared groups. Our study indicates that: i) centenarians of different ethnic origin have a different genetic background,&nbsp;ii) there is a possible association between longevity and allelic variants of ACE, even if only in specific ethnic groups (i.e.,&nbsp;Sardinian) and iii) ACE polymorphisms are a predisposing factor to hypertension.</p>
