Serum Levels of Selected Th17 and Th22 Cytokines in Psoriatic Patients

Introduction. Psoriasis is a T cell-mediated inflammatory disease in which pathogenesis T helper (Th) lymphocytes (Th1, Th17, and Th22) play an important role. The aim of the study was to assess the serum levels of some cytokines involved in the Th17 and Th22 responses in psoriatic patients. Material and Methods. The study comprised 60 psoriatic patients and 30 healthy controls. In the serum collected from psoriatic patients and healthy controls, the concentrations of IL-6, IL-12, IL-17, IL-20, IL-22, and IL-23 were examined with ELISA kits. Severity of psoriatic skin lesions was assessed by means of PASI, BSA, and PGA scores. Results. IL-6, IL-20, and IL-22 concentrations were significantly higher in psoriatic patients in comparison with the control group. The positive correlations between the concentrations of IL-22 and IL-20 and severity of psoriasis assessed with PASI and BSA scores as well as IL-17 and PASI score were found. There was also a positive correlation between IL-23 and IL-17 concentrations. Conclusions. Results of the conducted studies suggest that Th22 response may contribute to the skin and systemic inflammatory disease in psoriasis. It seems that early identification of soluble biomarkers and initiation of well-matched treatment may prevent exacerbation and progression of psoriasis.

Cardiovascular aspects of psoriasis: an updated review

Psoriasis, a systemic inflammatory disease, is associated with enhanced atherosclerosis and risk of cardiovascular (CV) disease, which may account for higher morbidity and mortality rates in psoriatic patients. It especially applies to younger psoriatic patients with more severe disease, reducing their life expectancy.

Metabolic syndrome in vitiligo.

Vitiligo is an acquired, depigmenting skin disease with still unclear, multifactorial etiopathogenesis. However, there is growing evidence that vitiligo affects not only the skin but it may also be connected with metabolic abnormalities, including glucose intolerance and lipid abnormalities, all of which confirms the systemic nature of the disease. Recently, it has been shown that melanocytes, especially those found in the adipose tissue, due to their ability to decrease inflammation and oxidative damage, are capable of preventing the metabolic syndrome. The article presents updated knowledge on potential metabolic disturbances in vitiligo.

Traditional Chinese medicine herbs — are they safe for psoriatic patients?

Although traditional Chinese medicine (TCM) relies on remedies of natural origin, its use is not always safe as it can have not only beneficial but also deleterious effects. Psoriatic patients, disappointed by conventional treatment and unaware of the potential side effects of TCM preparations, are increasingly reaching for non-traditional therapeutic methods. This review presents brief characteristics of selected Chinese herbs self-prescribed by psoriatic patients. It is important that dermatologists should be able to recognize any potential hazards connected with current or previous taking of these herbs by their patients.

Cardiovascular disease in psoriatic post-menopausal women.

It is generally accepted that the risk of cardiovascular disease (CVD) in women is significantly increased after the menopause. Hormonal changes associated with the menopausal transition may also alter the course of autoimmune diseases. It has been reported that menopause may exacerbate the symptoms of rheumatoid arthritis, systemic sclerosis and giant cell arteritis, but attenuate the course of systemic lupus erythemathosus. There is a growing body of literature indicating that the course of psoriasis may be altered by menopausal hormone changes. Considering the fact that both psoriasis and menopause are independent risk factors for CVD, and that menopause may exacerbate the course of psoriasis, a possible additive effect between these two conditions may be crucial for proper monitoring and treatment of peri‐ and post‐menopausal psoriatic patients.

Increased serum level of N-terminal Pro-B-type natriuretic peptide as a possible biomarker of cardiovascular risk in psoriatic patients.

Apparently, these days psoriasis is regarded as a systemic disease with frequent cardiovascular comorbidities, such as hypertension, myocardial infarction, valvular defects etc., which may lead to reduced lifespan or even sudden death. Therefore, it is important that biomarkers helpful in early detection or prediction of cardiovascular complications as well as their prevention should be identified. Even though the N‐terminal pro B‐type natriuretic peptide (NT‐proBNP) is a well‐known cardiovascular predictor in cardiovascular (CV) patients and in the general population, its usefulness in detection of CV comorbidities in psoriatic patients is still unclear.

Future diagnosis, today's treatment – cardiomyopathy in the course of psoriasis: a case report

Psoriasis is a relatively common, chronic skin disease of inflammatory origin. In recent years, public attention has been drawn to a more and more frequently observed relationship between psoriasis and cardiovascular disease. Nowadays, psoriasis is independently held responsible for increased cardiovascular mortality. It seems that the actual significance of the problem, together with a heart‐related death risk for these patients is often underestimated. This study presents clinical evidence collected during a long‐term observation and treatment of an 80‐year‐old psoriatic patient with concomitant diabetes, hypertension, and ischemic heart disease, whose overall clinical picture also suggested a congestive, inflammation‐related cardiomyopathy with conduction disorders and severe heart failure. Despite the patients advanced age and associated serious, long‐established psoriasis‐related problems, he was successfully treated with the use of interventional cardiology methods, as well as cardiac resynchronization therapy.

Risk Factors for Normal and High-Tension Glaucoma in Poland in Connection with Polymorphisms of the Endothelial Nitric Oxide Synthase Gene.

Aim The purpose of this study was to evaluate the influence of polymorphisms of the eNOS gene on the clinical status of patients with normal and high tension glaucoma. Methods 266 Polish Caucasian patients with primary open angle glaucoma were studied. Of the 266, 156 had normal tension glaucoma (NTG) and 110 high tension glaucoma (HTG). DNA material was isolated from peripheral venous blood using commercial kits. Real-time PCR reaction was used to amplify the promoter site of the endothelial nitric oxide synthase (eNOS) gene, including the single nucleotide polymorphism (SNP) site T-786C and part of the 7th exon of eNOS, including G894T SNP. Genotypes were determined with TaqMan SNP Genotyping Assays. Results There were no significant differences in frequencies of the allelic variants of both polymorphisms. In G894T SNP, however, the wild GG form was more common in the HTG group. The SNP of the eNOS gene did not significantly influence the progression rate in either of the groups studied. There were no differences in variants of the eNOS gene regarding the necessity for and success of surgery and the progression of the disease. In the NTG group, no statistical correlation was observed between G894T, T786C polymorphism variants, and risk factors such as optic disc haemorrhages, optic disc notches, and peripapillary atrophy. Mean diastolic and systolic pressure during the day and night were lowest in NTG patients with the CC variant of the T786C polymorphism. No statistical correlation was observed between the G894T and T786C polymorphisms and capillaroscopic examination results. Conclusions Genotype frequencies are similar for both the eNOS G894T and T-786C polymorphisms in NTG and HTG patients. These polymorphisms do not correlate with risk factors and do not influence the state of the capillary system in NTG patients. Systolic blood pressure is lower in NTG patients with mutated alleles of both polymorphisms.

Ultrasound findings in cutaneous sarcoidosis

The diagnosis of cutaneous sarcoidosis relies mainly on the patients history, presence of characteristic skin lesions and histological examination that shows a granulomatous, non-necrotizing dermal infiltration. The aim of the study was to assess the ultrasonographic features of cutaneous lesions of sarcoidosis before and after treatment. A 38-year-old woman with systemic sarcoidosis and specific cutaneous lesions was treated with systemic steroids followed by hydroxychloroquine. Ultrasonographic examination of the cutaneous sarcoidosis lesions was performed with a Philips iU 22 and Siemens Acuson S 2000 device, with the use of linear 15 MHz and 17 MHz transducers. Histological examination of skin lesions showed characteristic, naked, non-necrotizing granulomas in the upper dermis. Ultrasound examination revealed well-demarcated, hypoechogenic changes. Power-Doppler scan revealed increased vascularity within the lesions and the surrounding tissue. Clinical improvement of the skin lesions was confirmed by ultrasound examination, which showed a decrease in their size and normalization of dermal echogenicity and vascularity. Ultrasound examination can show cutaneous sarcoidosis lesions and their regression after appropriate treatment.

Videocapillaroscopic Alterations in Alopecia Areata

Alopecia areata (AA) is a common hair disorder observed in dermatological practice; however, the exact mechanisms that lead to the hair loss are still unknown. Disturbances in the blood supply of hair follicles may be one of the elements in the complex pathogenesis of AA. Nailfold videocapillaroscopy is a noninvasive technique that allows analysis of skin microcirculation in vivo. The aim of the study was the videocapillaroscopic assessment of skin microcirculation in AA patients. The study included 44 patients with patchy alopecia areata, 27 with alopecia universalis or totalis, and 40 healthy volunteers. Nailfold videocapillaroscopy was performed in all participants according to a standard protocol. Obtained images were assessed qualitatively and quantitatively. Two types of videocapillaroscopic images were distinguished in the study. Abnormal videocapillaroscopic images were found in 42% of patients. Tortuous and branching capillaries (P = 0.013, P = 0.001), decreased density of capillaries (P = 0.009), enlargement of the efferent limb (P < 0.017), or top part of the loop (P = 0.009) were observed significantly more often than in the control group. Only some patients with AA presented with microvascular abnormalities characterised by altered videocapillaroscopic images. More studies, including larger group of patients with AA, are required to determine the role of observed videocapillaroscopic alterations in AA.
