Preliminary Clinical Study On Ms Treatment With Hyperbaric Oxygenation

Abstract

The authors conducted the preliminary clinical investigation on 16 multiple sclerosis (Sclerosis multiplex) patients of median disease duration 9.33 years and symptoms evaluated on Kurtzke’s scale. The patients underwent between 25 and 30 hyperbaric oxygen exposures at a pressure of 2 ata in intervals spread over a few days. The patients were qualified and classified to the treatment symptomatologically according to Fisher but the obtained results were evaluated according to the standardised Disability Status Scale by Kurtzke. During the investigations the authors carried out additional quantitative immunoglobulin and complement activity determination, lymphocyte T and B determinations as well as the usually applied clinical and laboratory investigations. Evident clinical improvement was observed in 14 patients, but in the case of one patient a deterioration was observed after 15 hyperbaric expositions (resulting in the hyperbaric oxygen treatment being stopped), whilst in another case no curative effect could be observed. By utilising the 50% haemolysis method, within the examined immunological parameters the authors observed an increase of complement fractions and its activity, white lymphocytes T and B examined qualitatively did not maintain the characteristic shift. The authors are still discussing the obtained results.

Genetics of Psoriasis - Short Resume

Genetics of Psoriasis - Short Resume

Psoriasis is a disease with a genetic background (4). Several psoriasis susceptibility loci (PSORS) have been found on various chromosomes: PSORS1 on 6p21.3, PSORS2 on 17q, PSORS3 on 4q, PSORS4 on 1q21, PSORS5 on 3q21, PSORS6 on 19p, PSORS7 on 1p, PSORS8 on 16q, PSORS9 on 4q31, PSORS10 on 18p11, PSORS11 on 5q31-q33 and PSORS12 on 20q13. (27). However, the exact genes and their functions, or their respective malfunctions, in psoriasis and arthritis have not been unambiguously identified. Recently, it has been argued that PSORS1 may indeed be the HLA-Cw*06 allele encoding the HLA-Cw6 molecule (35).

Psoriasis is a chronic inflammatory disease of skin that also often affects joints and nails. This disorder is characterized by hyperproliferation of keratinocytes, activation of angiogenesis, vasodilatation and mainly by lymphocyte infiltration of dermis and epidermis (45). The process of maturation of keratinocytes is accelerated and thus not quite terminated. Psoriatic lesion appears on skin.

Skin manifestations are typically red bounded areas of different size and shape with characteristic silvery scales (9). Lesions appear mostly on the skin of elbows and knees, scalp including genitals. Individual manifestations differ in size and severity from localized lesions to whole body involvement. Very often psoriasis affects nails of hands and feet. It can also cause inflammatory changes on joints, named as psoriatic arthritis. Similarly to rheumatoid arthritis and sclerosis multiplex, psoriasis is classified as an immune mediated inflammatory disorder. Those disorders are characterized by chronic progression of an inflammatory process and important role of TNF alpha. Because of the role of TNF alpha in pathogenesis, we can use its inhibitors in therapy. It also affects progress of different comorbidities such as diabetes mellitus 2 and cardiovascular problems (21). Patients with psoriasis have often other risk factors for atherosclerosis such as lipid metabolism disorders and overweight (37).
