The role of VEGF in psoriasis: an update

Psoriasis is a common, chronic immune-mediated multifactorial skin disease. In its pathogenesis altered differentiationand hyperproliferation of keratinocytes, dysregulation of immunological cell functions, together withabnormal angiogenesis are involved. Angiogenesis is defined as the formation of new blood vessels from thepre-existing vascular bed. This complex and multistep process is regulated by different factors among whichvascular endothelial growth factor (VEGF) is considered to be the most important. The aim of this paper isa review of the current literature considering the role of vascular endothelial growth factor in psoriasis. Manystudies have focused on the role of VEGF in psoriasis and revealed its increased serum and tissue levels whichcorrelated with disease severity. Recent data indicate that VEGF is not only responsible for angiogenesis, butalso regulates keratinocyte differentiation. Moreover, it has been suggested that vascular endothelial growthfactor could be a link between psoriasis and its comorbidities. So far, there are single clinical cases that reportedclearance of psoriasis after anti-VEGF therapy. Therefore, the VEGF pathway might be a potential new therapeuticalternative leading to improvement of psoriasis. However, further clinical studies are needed to evaluatethe efficacy and safety of this therapy in psoriasis

Genes and structure of selected cytokines involved in pathogenesis of psoriasis.

Psoriasis is a common skin disease involving 1-4% of human population worldwide, of strong genetic background. The following cytokines are directly involved in psoriasis: TNF, IL-1, IL-2, IL-6, IL-7, IL-8, IL-15, IL-18, IL-19, IL-20, IL-23 whereas IL-4, IL-10, IL-12 as well as IL-11, IL-17 and IFN-gamma are rather indirectly engaged. This work is a review of some genetic factors and structure of selected cytokines and receptors and their genes location

Use of alternative methods in the treatment of anemia in pregnant women – prospective observational study

Objectives: Anemia in pregnant women is a common condition, diagnosed when the concentration of hemoglobin falls below 11 g/dL. Taking into consideration the accounts of nephrologists about good results of treatment of secondary anemia using erythropoietin in patients with renal failure, we tried to use EPO to cure anemia in pregnant women.  The aim of the study was to evaluate the results of EPO treatment on pregnant women diagnosed with iron deficiency anemia, as well as possible side effects.  Material and methods: The study consisted of 25 patients: Group I — treated with iron supplement administered parenterally — Ferrum Lek every two days intramuscularly.  Group II — treated with recombinant human erythropoietin — 1000 j intravenously every three days, with oral iron sup- plements.  Results: After a week of treatment the positive response was higher in the second group (92.3% in II, vs 33.3% in I, p < 0.005). The average increase of hemoglobin and RBC was significantly higher in II group.  An increase in hemoglobin did not correlate with the age of women (r = 0.07) or with the duration of pregnancy (r = 0.08). However, a negative correlation was found between basic hemoglobin level and its increase after treatment (r = 0.602).  Conclusions: EPO administered with the oral dose of iron in pregnant women with anemia caused by iron deficiency shows higher effectiveness than the use of iron preparations parenterally.  The usage of EPO during pregnancy is not related to any dangerous side effects for the mother or fetus.

High Frequency Ultrasonography of the Skin and Its Role as an Auxillary Tool in Diagnosis of Benign and Malignant Cutaneous Tumors – A Comparison of Two Clinical Cases

The number of dermatologic entities that can be studied by ultrasound examination (US) of the skin is increasing. Conventional US and high frequency US (HFUS) are considered useful additional tools in improving the diagnosis and management of common benign and malignant skin tumors. US may help in positive and differential diagnosis of primary melanocytic neoplasms and of locoregional spread in melanoma patients. US preoperative evaluation of primary melanoma thickness correlates with histologically estimated melanoma thickness, and can help determine surgical margins and indications for sentinel lymph node biopsy. It is also useful during follow-up after surgical treatment for early detection of recurrence or metastases. In this case report, we present two cases of skin lesions clinically suspicious for malignancy. The first lesion was a round nodule 3 mm in diameter, resembling a blue nevus. In HFUS it was well delimited, hypoechoic, and well vascularized. The second lesion presented as an elevated, well-circumscribed nodule, 5-6 mm in diameter, inhomogeneous in color. HFUS depicted a poorly delimited, irregular, hypoechoic lesion crossing the dermoepidermal junction. At the first exam it was not vascularized, but 6 months later a number of vascular flow signals within the lesion were found. In histopathological examination the lesions were finally diagnosed as, respectively: benign cavernous hemangioma and melanoma. In both presented cases HFUS proved to be useful in a differential diagnosis of suspicious skin lesions. Noninvasive and easy to perform, HFUS is a valuable diagnostic method in dermatology.</p

Psoriasis vulgaris and digestive system disorders: is there a linkage?

Psoriasis is well-known immune-mediated skin disease often associated with co-morbidities, including dyslipidaemia and obesity. Few reports imply that the disease might be also related to pathology of mucosal surfaces, especially that of the digestive system. The authors present a case of psoriasis and concurrent digestive system abnormalities, and review the literature regarding the topic. A 40-year-old man suffered from an exacerbation of exudative psoriasis for about 6 months. Topical antipsoriatics proved ineffective and the disease gradually progressed to a severe disseminated form. Subsequent detailed examinations revealed persistent gastroduodenitis due to H. pylori infection, pancreatic dysfunction and fatty change of the liver, although the patient denied any gastrointestinal symptoms. As a result appropriate treatment of the diagnosed digestive system disorders was added to topical antipsoriatic therapy. Within 2 weeks of treatment clinical symptoms and laboratory signs showed a marked trend to normalisation. The presented medical history seems to suggest that there may be some kind of interplay between psoriasis and digestive system disorders

Eruption of palmoplantar pustular psoriasis in patient treated with anti-androgen therapy for prostate cancer and aggravation of lesions after statin treatment

Abstract The article focuses on the eruption of palmoplantar pustular psoriasis, which was documented in a 53-year-old man diagnosed with prostate cancer with bone metastases. This clinical finding was made during routine hormone therapy and palliative radiotherapy. The local improvement in skin lesions was achieved following administration of topical ointments and the use of UVA 311 nm radiation therapy. The management of prostate cancer in this subject resulted in malaise, onset of diabetes mellitus and increased concentration of serum lipids. Interestingly, a few days after the statin treatment was initiated, the intensive pustule eruption was observed as well as severe pain and burning sensation in the palms and soles. The dermatological treatment led to significant improvement. The patient is still receiving oncological therapy and is monitored by dermatologists on a regular basis

Genital psoriasis: a hidden multidisciplinary problem — a review of literature

Genital psoriasis is a variety of autoimmune dermatological disease — psoriasis with relapsing-remitting course, which can have an onset in all age groups. It is most often diagnosed at an advanced stage. Genital psoriasis is considered an embar­rassing condition and is often misjudged as a sexually transmitted disease or allergic reaction due to low social awareness of the disease. The manifestations of genital psoriasis may differ from typical genital dermatoses and with symptoms such as itch, erythroderma and vaginal discharge may mimic other diseases at an early stage. The diagnosis and treatment of genital psoriasis may be difficult and often requires a multidisciplinary approach. The aim of this article is to present the literature review of genital psoriasis concentrating on the clinical presentation, treatment and influence on the quality of patients’ life and sexual activity disorders

Plasma Interleukin-18 and Dendritic Cells in Males with Psoriasis Vulgaris

Peripheral blood dendritic cells seem to play a crucial role in psoriatic inflammatory processes. The aim of our study is to investigate the relationship between plasma interleukin-18 (IL-18) levels and blood dendritic cells in psoriatic patients. IL-18 plasma levels were measured by ELISA. Phenotypes of dendritic cell subsets were analyzed by double-colour flow cytometry. Plasma IL-18 level in psoriatic males was significantly higher, whereas counts of BDCA-2+ cells were lower than in the control group. The myeloid/plasmacytoid ratio was significantly higher in the patient group compared to the control one. In the patient group, significant negative correlations between plasma IL-18 level and both the BDCA-1+ and BDCA-2+ counts were found. BDCA-1+ counts correlated negatively with percentage of skin involvement. IL-18 seems to play a role in psoriasis pathogenesis. The decreased counts of blood plasmacytoid DCs in psoriatic patients might result from IL-18 down-regulation of plasmacytoid DC precursor proliferation
