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

Lipid Disturbances in Psoriasis: An Update

Psoriasis is a common disease with the population prevalence ranging from 2% to 3%. Its prevalence in the population is affected by genetic, environmental, viral, infectious, immunological, biochemical, endocrinological, and psychological factors, as well as alcohol and drug abuse. In the recent years, psoriasis has been recognised as a systemic disease associated with numerous multiorgan abnormalities and complications. Dyslipidemia is one of comorbidities in psoriatic patients. Lipid metabolism studies in psoriasis have been started at the beginning of the 20th century and are concentrated on skin surface lipids, stratum corneum lipids and epidermal phospholipids, serum lipids, dermal low-density lipoproteins in the psoriatic skin, lipid metabolism, oxidative stress and correlations between inflammatory parameters, lipid parameters and clinical symptoms of the disease. On the basis of the literature data, psoriasis can be described as an immunometabolic disease

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

Somatyczne i pozasomatyczne problemy związane z łuszczycą w ciąży

Zmiany hormonalne, metaboliczne oraz immunologiczne występujące w okresie ciąży w istotny sposób wpływają na funkcjonowanie skóry. Łuszczyca należy do najczęstszych schorzeń dermatologicznych i zaliczana jest do nieswoistych dermatoz okresu ciąży. Celem artykułu jest przedstawienie znaczenia wsparcia w przebiegu łuszczycy u kobiet ciężarnych. Ciąża w różny sposób wpływa na przebieg łuszczycy. Łuszczyca może powodować wystąpienie nawracających poronień, przewlekłego nadciśnienia tętniczego, cukrzycy, otyłości prowadząc do wystąpienia powikłań okołoporodowych i porodu przedwczesnego. W sytuacji stwierdzenia współistnienia łuszczycy w ciąży konieczne jest wdrożenie profilaktyki w sferze emocjonalnej i objęcie ciężarnych wsparciem i opieką psychoterapeutyczną. Wspieranie ciężarnej z łuszczycą wymaga od personelu medycznego umiejętności oceny stanu psychicznego kobiety oraz wiedzy w zakresie chorób skóry.Hormonal, metabolic and immunological changes occurring during pregnancy have significant effects on the function of the skin. Psoriasis is one of the most common dermatological diseases and it is known as a nonspecific dermatosis in pregnancy. The aim of this article is to present the importance of support in the course of psoriasis in pregnant women. Psoriasis may cause recurrent miscarriages, chronic hypertension, diabetes or obesity, leading to perinatal complications and premature birth. The coexistence of psoriasis and pregnancy requires emotional prophylaxis, as well as support and psychotherapeutic care. Medical staff requires knowledge of skin diseases and skills to assess a patient’s mental state

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

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
