Analysis of key markers: IL-10/sHLA-G in psoriasis patients and the identification of 14-bp INDEL in the HLA-G gene.

Background: Psoriasis is a chronic inflammation resulting from interactions between immunological and genetic factors. An important tolerogenic role in this autoimmunological disease is played by HLA-G, which is modulated by IL-10. Therefore, this study (N.

Clinicopathologic retrospective analysis of annular pustular psoriasis.

Annular pustular psoriasis (APP) is a rare form of pustular psoriasis with a chronic relapsing course and a good prognosis. The clinical picture is characterized by erythematous lesions, usually polycyclic, with the presence of small, sterile pustules on the circumference of the lesions and fine peeling. We present two cases of APP with diagnostic problems: a 65-year-old woman that suffered from intermittent APP with remission and exacerbation for many years, and an 83-year-old man with lesions that developed after atenolol treatment.

Presence of DNA in blood cells is a frequent event in patients with the late stage of primary cutaneous lymphomas and with atopic dermatitis.

Introduction: Microbial infection and associated super antigens have been implicated in the pathogenesis of cutaneous T-cell lymphoma (CTCL), and many patients die from complicating bacterial infections. It has been postulated that () infection may be involved in the pathogenesis of (MF) but published data are limited and controversial.

Aim: To analyze the frequency of () DNA presence in blood samples of lymphoma cases.

The effect of subcutaneous methotrexate on markers of metabolic syndrome in psoriatic patients - preliminary report.

Introduction: Methotrexate (MTX) has anti-proliferative and anti-inflammatory effects in psoriasis. Moreover, low doses can reduce the risk of developing cardiovascular diseases. It turns out that psoriasis and atherosclerosis have a similar pathogenetic mechanism: the same pro-inflammatory cytokines, Th1 and Th17, are involved in both diseases.

Frequency of streptococcal upper respiratory tract infections and HLA-Cw*06 allele in 70 patients with guttate psoriasis from northern Poland.

Introduction: The association of guttate psoriasis with a streptococcal throat infection and HLA-Cw*06 allele is well established in different populations. Nevertheless, only few studies on this form of disease have been performed in the Polish population.

Aim: To analyze the frequencies of streptococcal-induced guttate psoriasis and HLA-Cw*06 allele in 70 patients with guttate psoriasis originating from northern Poland.

Oral retinoids and rexinoids in cutaneous T-cell lymphomas.

Retinoids are biologically active derivatives of vitamin A modulating cell proliferation, differentiation, apoptosis and altering the immune response. They have been used for years in therapy of cutaneous T-cell lymphomas (CTCL) but the exact mechanism of retinoids' action is unclear. It is based on the presence of specific receptors' families, mediating the biological effects of retinoids on the tumor cells: retinoic acid receptor (RAR) and retinoic X receptor (RXR).
