The treatment is carried through with topical medicines, fototerapia and medicines of verbal use (COAST; AXE; SELORES, 2005). Called of psorase severe (figure 9) she is that one that more than involves 10% of the body that can be covered with psoriaticas plates or pstulas or alastramento of psorase eritrodrmica. The patients who present this category of psorase tend to develop psoriatica artrite. The treatment includes fototerapia, verbal medication or a combination. The severity of psorase can be aggravated by injuries and irritation of the skin, solar exposition, estresse and anxiety, some medicines, infections and diet (GULBENRIAN, 2006). Figure 7: Light Psoriase in plates Source: Figure 8: Moderate Psoriase in plates Source: Figure 9: Inverse or flexural Psoriase severe Source: 3.1A Psorase and the Imunolgico System psorase is a imunolgica illness, the defense system is divided in innate system and adaptativo or acquired system and functions in integrated way and coordinate, being thus so that all the events occur in synchronous way; a net of intracellular Inter communication exists and.
The innate answers are inespecficas, unprovided of memory and they are decurrent of natural physical and/or chemical barriers as the unbroken skin, mucosae and enzymes. The adaptativo system can be enlisted through the release of citocinas and the antigenic presentation for the cells antigen presenters, that potencializam the defenses of the host. This system is characterized by the presence of cells of memory capable to recognize the aggressive agents to each new contact with antigens being thus produced faster and efficient answers, the cells that act in the adaptativo system are the linfcitos T and B and the cells of Langerhans in the skin, that they are the cells antigen presenters. Beyond these cells, diverse molecules are involved in the development and maintenance of the immune reply, the citocinas and the antibodies produced for the linfcitos, beyond some proteins gifts in the serum, known as proteins of acute phase, as, for example, the C-reactive protein.
