    Fatty acid binding protein 5 (FABP5) is elevated in psoriatic keratinocytes and could be involved in systemic metabolic disturbances in psoriasis. The aim of the study was to evaluate serum FABP5 in obese and non-obese psoriatic patients, to assess the relationship between FABP5 and the duration, severity of the disease, inflammatory and metabolic markers and influence of treatment with narrowband—ultraviolet B (NB-UVB). Seventy-four patients (30 treated with NB-UVB) with psoriasis were enrolled in the study. The serum concentrations of FABP5 were measured using Human FABP5 Enzyme-Linked Immunosorbent Assay kit. Serum fatty acids were measured by gas–liquid chromatography. Serum FABP5 levels in psoriatic patients were higher versus control group (P < 0.001). FABP5 in patients with PASI > 20 was higher compared to the mild group (PASI < 10) (P < 0.001) and serum FABP5 correlated positively with PASI score (r = 0.41, P < 0.001). There was also positive correlation betwe...

    Skin, as the outermost organ of the body, is constantly exposed to both intrinsic and extrinsic causative factors of aging. Intrinsic aging is related to compromised cellular proliferative capacity, and may be accelerated by harmful environmental influences with the greatest significance of ultraviolet radiation exposure, contributing not only to premature aging, but also to skin carcinogenesis. The overall skin cancer burden and steadily increasing global antiaging market provide an incentive for searching novel targets to improve skin resistance against external injury. Sirtuin 1, initially linked to extension of yeast and rodent lifespan, plays a key role in epigenetic modification of proteins, histones, and chromatin by which regulates the expression of genes implicated in the oxidative stress response and apoptosis. The spectrum of cellular pathways regulated by sirtuin 1 suggests its beneficial impact on skin aging. However, the data on its role in carcinogenesis remains contr...

    Background Recent studies point out the important role of vitamin D in the pathogenesis of many autoimmune diseases, in between psoriasis. Vitamin D regulates function of the dendritic cells, proliferation and maturation of the keratynocytes and lymphocytes T. The aim of the study was to evaluate serum vitamin D (25OHD) concentrations in psoriatic patients in the north-east of Poland and their comparison in the summer and winter period of the year. We also evaluated relationship between 25OHD concentration and disease severity, prevalence of psoriatic comorbidities and laboratory results. Material and Methods 25OHD serum concentration was evaluated by electrochemiluminescent method in 115 patients with exacerbated plaque type psoriasis. 39 patients were evaluated in the summer and 79 in the winter time. 28 patients from winter group were treated with narrow band ultraviolet B radiation (NB-UVB). The results were compared with 38 healthy persons. Results 25OHD serum concentrations of...

    INTRODUCTION Erysipelas is a bacterial infection, caused by group A β-hemolytic streptococci (Streptococcus pyogenes), rarely other bacteria. It is characterized by sudden onset and rapid course, with the presence of systemic symptoms. OBJECTIVE A retrospective analysis of patients hospitalized for primary and recurrent erysipelas with particular consideration of clinical profile of patients, causes, complications and risk factors of the recurrence. MATERIAL AND METHODS We have analyzed the medical records of patients hospitalized for erysipelas at the Dermatology and Venereology Department of the Medical University of Bialystok from 2011 to 2015. RESULTS One hundred twenty female (53,8%) and 103 male (46,2%) were included in the study. The median age was 61. The first episode of clinical symptoms was observed in 78% patients, while 22% of them were diagnosed as recurrent erysipelas. Skin lesions in both cases were located in the lower extremities most often. Mechanical trauma was statistically more frequently cause of the disease in men, while venous insufficiency and ulcers in women. Complications such as abscess, ulceration, phlegmon and thrombosis were observed in 22% of patients, significantly more common in men. Patients who were hospitalized more than 10 days were more likely to have higher body mass index and higher indicators of inflammation than patients who required a shorter hospital stay. Recurrent erysipelas was more often diagnosed in patients with co-morbidities, including hypertension, overweight, venous insufficiency and diabetes. CONCLUSIONS Erysipelas located in the lower extremities, high temperature on admission, higher indicators of the inflammation, complications and coexistence of obesity and diabetes are the risk factors of the prolonged hospital stay. Primary and recurrent erysipelas have a similar course, severity of the disease and duration of hospitalization.

    This study is the first to assess redox balance, glutathione metabolism, and oxidative damage to RNA/DNA, proteins, and lipids in the plasma/serum and urine of patients with adrenal masses. The study included 70 patients with adrenal tumors divided into three subgroups: incidentaloma ( n = 30 ), pheochromocytoma ( n = 20 ), and Cushing’s/Conn’s adenoma ( n = 20 ), as well as 60 healthy controls. Blood and urine samples were collected before elective endoscopic adrenalectomy. Antioxidant defense capacity was significantly decreased (serum/plasma: superoxide dismutase (SOD), catalase (CAT) and reduced glutathione (GSH), uric acid (UA); urine: SOD, GSH, UA) in patients with adrenal masses. The oxidative damage to proteins (advanced glycation end products (AGE), advanced oxidation protein products (AOPP)) and lipids (lipid hydroperoxides (LOOH), and malondialdehyde (MDA)) was higher in the plasma and urine of these patients. Plasma MDA and DNA/RNA oxidation products, with high sensitivi...

    Psoriasis is a chronic and recurrent skin disease, affecting 1.5-3% of the population. It is characterized by abnormal epidermal proliferation, immunological disturbances with predominance of the Th1 response, and complex pathogenesis. Correlations have been found between psoriasis and obesity, cardiovascular diseases, diabetes and metabolic syndrome. Adipokines, bioactive substances secreted by adipose tissue, exhibit a variety of metabolic activities and are associated with many diseases. Based on current literature data, we discussed the possible role of adiponectin in psoriasis. SŁOWA KLUCZOWE: łuszczyca, otyłość, adipokiny, adiponektyna.

    The results of recent studies indicate the key role of nitrosative stress and protein oxidative damage in the development of morbid obesity. Nevertheless, the effect of bariatric surgery on protein oxidation/glycation and nitrosative/nitrative stress is not yet known. This is the first study evaluating protein glycoxidation and protein nitrosative damage in morbidly obese patients before and after (one, three, six and twelve months) laparoscopic sleeve gastrectomy. The study included 50 women with morbid obesity as well as 50 age- and gender-matched healthy controls. We demonstrated significant increases in serum myeloperoxidase, plasma glycooxidative products (dityrosine, kynurenine, N-formyl-kynurenine, amyloid, Amadori products, glycophore), protein oxidative damage (ischemia modified albumin) and nitrosative/nitrative stress (nitric oxide, peroxy-nitrite, S-nitrosothiols and nitro-tyrosine) in morbidly obese subjects as compared to lean controls, whereas plasma tryptophan and to...

    In this pathbreaking study, we evaluated nitrosative stress in morbidly obese patients with and without metabolic syndrome. 62 women with class 3 obesity (BMI>40 kg/m2) were divided into three subgroups: obese patients (OB), obese patients with hypertension (OB+HYP), and obese patients with metabolic syndrome (OB+MS). In comparison to the lean patients, OB had increased levels of serum myeloperoxidase (MPO), plasma nitric oxide (NO), S-nitrosothiols, and peroxynitrite (ONOO−), as well as nitrotyrosine, while oxidized glutathione (GSSG) rose only in OB+HYP group. Interestingly, ONOO− was significantly higher in OB+HYP and OB+MS as compared to OB group, while MPO only in OB+MS group. OB+MS had greater nitrotyrosine and S-nitrosothiol values than OB+HYP. Moreover, peroxynitrite could differentiate OB from OB+HYP and OB+MS (AUC 0.9292; p<0.0001; 87.5% sensitivity, 90% specificity) as well as between OB and OB+MS group (AUC 0.9125; p<0.0001; 81.25% sensitivity, 83.33%). In concl...

    The assessment of total antioxidant activity seems to have a higher diagnostic value than the evaluation of individual antioxidants separately. Therefore, this is the first study to assess the total antioxidant/oxidant status in morbidly obese patients undergoing bariatric surgery. The study involved 60 patients with Class 3 obesity (BMI > 40 kg/m2) divided into two equal subgroups: morbidly obese patients without and with metabolic syndrome. The analyses were performed in plasma samples collected before surgery as well as 1, 3, 6, and 12 months after a laparoscopic sleeve gastrectomy. Total antioxidant capacity (TAC), ferric-reducing antioxidant power (FRAP), DPPH (2,2′-diphenyl-1-picrylhydrazyl) radical assay, and total oxidant status (TOS) were significantly higher before surgery (as compared to the healthy controls, n = 60) and generally decreased after bariatric treatment. Interestingly, all assessed biomarkers correlated positively with uric acid content. However, the total...

    This is the first study to evaluate both the antioxidant barrier, glutathione metabolism, and oxidative damage to proteins and lipids in morbidly obese patients undergoing bariatric treatment. The study included 65 patients with class 3 obesity divided into two subgroups: morbidly obese patients without metabolic syndrome (OB) and obese patients with metabolic syndrome (OB + MS). Blood samples were collected before surgery as well as one, three, six, and twelve months after the bariatric treatment. Superoxide dismutase and reduced glutathione (GSH) were significantly decreased, whereas glutathione reductase and uric acid were enhanced in morbidly obese patients before bariatric surgery as compared to lean control. Moreover, in the OB group, we observed the increase of superoxide dismutase (SOD) and the decrease of uric acid (UA) after the bariatric treatment; however, these changes were not observed in the OB + MS group. The oxidative damage to proteins (advanced glycation end produ...

    Abstract: Psoriasis is a chronic, recurrent, inflammatory disease. Recent investigations indicate an autoimmune pathogenesis of the disease. Apoptosis plays an important role in the regulation of immune mechanisms in many autoimmune diseases. Although CD40, CD40L, and Bcl-2 have already been studied in psoriatic skin lesions, little is known about their circulating forms. The aim of the present study was to evaluate the serum concentra-tions of Bcl-2, soluble CD40 and CD40L in psoriatic patients. The study was performed using ELISA kits in 39 psoriatic patients before treatment and after two weeks of topical ointment. Data was analyzed with respect to severity of psoriasis, duration of the disease, and coexisting psoriatic arthritis. Our results revealed that serum concentrations of soluble CD40 and CD40L before and after treatment were significantly higher (p < 0.01 and p < 0.001) in patients with psoriasis compared to the control group. Topical treatment of psoriatic lesions...

    Introduction. Tinea faciei is quite a rare infection in the developed countries. Proper diagnosis of the causative pathogen is essential for successful treatment. Objective. To present the case of an 11-year-old patient in whom wrong diagnosis and treatment led to complications and finally to face deformation. Case report. A small inflammatory skin lesion appeared on the chin and extended quickly to form a deep infiltration. Despite surgical incision, drainage and broad-spectrum antibiotics, the skin lesion progressed to an ulceration of 2 × 3 cm in diameter with necrotic crust. In direct mycological smear hyphae were observed and in the culture Stenotrophomonas maltophilia was found. Systemic treatment with terbinafine and trimethoprim-sulfamethoxazole led to almost complete healing with a scar and chin deformation as a result.

    Disturbances in amino acids metabolism are common in chronic renal failure and subside partially after renal tranplantation. Tryptophan (TRP) is one of the most important exogenous amino acids. Its main derivative is L-kynurenine (KYN). Disorders in the TRP metabolism via kynurenine pathway may lead to neurologic disturbances, hypertension and anaemia. The aim of this study was to assess peripheral kynurenine pathway in 28 renal allograft recipients (RAR) (12 women and 16 men) in comparison to 10 hemodialysed patients with chronic renal failure (CRF) and 10 healthy subjects. TRP, KYN, 3-hydroxykynurenine (3-HKYN), kyn-urenic acid (KYNA) and quinolinic acid (QA) were determined in plasma using high performance liquid chromatography technique. The plasma concentration of tryptophan in RAR was not significantly different from the control group, but it was almost twice higher than in CRF. There was an increase in most of kynurenine metabolites in RAR as compared to healthy subjects, alt...

    The sexually transmitted infection (STI) in an infant can be an early consequence of child sexual abuse (CSA). The risk of acquisition of a STI depends, among others, on the prevalence of these infections in the abusing population and the type of sexual assault. As the detection of sexually transmissible organism can be an unique evidence of CSA, only the best standardized methods should be used for the diagnosis of STIs in children. STIs are seen in less than 10% of abused child and in a half of them are asymptomatic. The relevance of STIs for the diagnosis of CSA should be assessed taking into consideration the age of a child, a type of sexually transmissible organism and its localization. Generally, postnatally acquired gonorrhoea, syphilis and genital Chlamydia trachomatis infection in a child more than 2-year old are most clinically evident for CSA. Infections with HPV, HIV and HSV can also be important.

    Renal transplantation is considered the only good long-term therapy for chronic renal failure. Better surgical techniques and recent advances in immunosuppressive therapy allow patients to survive for many years, free from any complications due to rejection. However, cutaneous lesions can be a significant problem for this group of patients. Immunosuppression predisposes them to infections--predominantly viral, but also fungal and bacterial ones, as well as malignant tumours like basal cell carcinoma, squamous cell carcinoma, melanoma and Kaposi's sarcoma. The review of the current literature on skin manifestations in renal transplant recipients is done.

    ObjectiveTumor necrosis factor-α (TNF-α) and its receptors play important roles in the induction and maintenance of psoriatic lesions. Selenium (Se), a trace element with immunomodulatory properties, is usually decreased in psoriasis patients. We examined the influence of Se supplementation on soluble TNF-α receptor type 1 (sTNF-R1) and topical treatment in psoriasis patients.

    Vascular endothelial growth factor (VEGF) demonstrating pro-angiogenic activity promote new blood vessel formation in psoriatic lesions. The aim of this study was to evaluate the serum concentrations of VEGF, its soluble receptors (sVEGF R1 and R2) and VEGF content in scales of patients with psoriasis. To analyze possible association with activity of the disease, serum and scales from plaques were collected from 59 patients with exacerbated chronic plaque-type psoriasis. Mean concentrations of VEGF and sVEGF R1 in sera of patients were respectively two and four times higher than in healthy controls. Serum VEGF and sVEGF R1, but not sVEGF R2 demonstrated significant correlation with psoriasis area and severity index (PASI). There was also significant correlation between VEGF levels in serum and scales. Serum sVEGF R1 concentration was significantly elevated even in patients with low psoriasis activity (PASI<10), whereas increase of serum VEGF became significant in patients with medium activity (PASI: 10-20). Levels of serum VEGF and sVEGF R1 were the highest in patients with PASI>20. We confirmed association of both serum and scales VEGF concentrations with degree of psoriasis activity and demonstrated predominant increase of sVEGF R1 vs. VEGF in serum of patients with low psoriasis activity.

    Psoriasis is a chronic, recurrent, inflammatory disease. Recent investigations indicate its autoimmune pathogenesis. Apoptosis plays an important role in the development of many autoimmune diseases. The aim of this study was to evaluate the influence of topical treatment of psoriasis on soluble Fas (sFas) and soluble Fas-ligand (sFasL). Serum concentrations of sFas and sFasL were measured using ELISA in 40 psoriatic patients before and after topical treatment with dithranol and compared to the values obtained from 16 healthy subjects. Data were analyzed with respect to severity of psoriasis, duration of the disease and coexisting obesity, diabetes and hypertension. We found that serum levels of sFas before (11.9±2.4ng/mL) and after treatment (12.2±2.5ng/mL) were significantly higher in patients with psoriasis as compared to the control group (6.4±1.8ng/mL). Concentrations of sFasL did not differ significantly from healthy subjects, but increased after treatment. The sFas/sFasL ratio was significantly higher in psoriasis (128±47) than in the control group and, even though it tended to decrease after treatment, it still remained higher than in the control group (65±22). Additionally we observed a positive correlation of sFas/sFasL ratio with the age of patients and duration of the disease. Psoriatic patients suffering from hypertension and overweight had significantly higher sFas/sFasL ratio than other psoriatic patients. Our data indicate upregulation of the sFas/sFasL system in psoriatic patients. We demonstrate association of sFas/sFasL with commorbidities - components of metabolic syndrome.
