[Show abstract][Hide abstract] 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 concentrations 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 with dithranol ointment failed to decrease serum of CD40 and CD40L, which has not been described until now. There was no significant difference in serum Bcl-2 concentration between the compared groups. We did not find significant differences in serum concentrations of Bcl-2, CD40 or CD40L between patients with mild or severe psoriasis, nor any correlation between disease duration and the presence of psoriatic arthritis symptoms. Our data indicates upregulation of the CD40/CD40L system in psoriatic patients despite topical treatment and suggests their possible role in the pathogenesis of psoriasis.

We describe a case of lupus vulgaris in a 72-year-old male patient with a single lesion localized on his lower extremity, developing for 30 years before correct diagnosis and previously treated with topical steroids. Bacillus infection in other organs was not detected. Diagnosis of tuberculosis was made based on personal history, clinical picture, hypersensitivity to tuberculin, histopathology and polymerase chain reaction. A multidrug therapy with rifampicin, isoniazid and pyrazinamide resulted in regression of the lesion. The common lack of knowledge about the clinical picture of cutaneous tuberculosis causes its late diagnosis and treatment.

[Show abstract][Hide abstract] ABSTRACT: Vascular endothelial growth factor (VEGF) is recognized a pivotal pro-angiogenic factor responsible for new blood vessels formation in psoriatic lesion.
The aim of the study was to analyse serum concentrations of VEGF and its soluble receptors (sVEGF) R1 and R2 in psoriatic patients before and after treatment.
Serum samples were collected before and after 14 days of standard topical therapy, from 44 patients with exacerbated chronic plaque-type psoriasis and VEGF, sVEGF R1 and sVEGF R2 concentrations were measured using an enzyme immunoassay. Data were analysed with respect to baseline values of the psoriasis area severity index (PASI).
Baseline mean serum levels of VEGF and sVEGF R1, but not sVEGF R2 were significantly higher in patients than in healthy controls. VEGF demonstrated significant correlation with PASI score. Treatment resulted in significant reduction of VEGF serum concentration, particularly in patients with severe course of the disease (PASI >20) and increase in sVEGF R1 concentration in patients with mild disease activity (PASI <10). Moreover, serum sVEGF R1 level after treatment termination was significantly higher in patients with mild than severe course of psoriasis.
We confirmed the association between psoriasis activity and serum VEGF concentrations, which can be recognized as an indicator of the disease severity. However, the increase of serum sVEGF R1 concentrations can predict amelioration of clinical signs.

[Show abstract][Hide abstract] ABSTRACT: 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.
[Show abstract][Hide abstract] ABSTRACT: PURPOSE: Necrotizing fasciitis (NF) is a rare, life-threatening soft-tissue infection, characterized by rapidly spreading inflammation, with secondary necrosis of the fascia and surrounding tissues. It is mostly caused by group A beta-haemolytic streptococci or multibacterial. A case of the 25-year-old man admitted on September 2006 to the Department of Dermatology and Venereology with suspicion of erysipelas of the left upper limb and left foot is presented. On admission the pain, erythema, diffuse oedema of the left upper limb and erythema of the left foot were observed. Laboratory results revealed elevated: ESR, acute phase parameters (C-reactive protein, D-dimer), CPK and fibrinogen. Within 72-hours, despite treatment with antibiotics and anticoagulants, the oedema and pain increased, initial necrosis of the skin and extreme local tenderness appeared. Suspecting NF the patient had been transported to the Department of Surgery from where, after surgical debridement of devitalized tissue, was moved to the Intensive Care Unit and then transferred to the National Centre of Hyperbaric Medicine of the Medical University of Gdansk. Despite of repeated debridement, aggressive antibiotic therapy and hyperbaric oxygen therapy, necrosis was spreading. The patient developed sepsis and acute respiratory distress syndrome. Amputation of the left upper limb was performed. Five months later patient was admitted to ICU in Bialystok after a suicide attempt. After next four months he died. The dramatic course of the disease is the evidence, that having an adequate knowledge about early symptoms of NF can save patient's life.

[Show abstract][Hide abstract] ABSTRACT: Tumour necrosis factor alpha converting enzyme (TACE) is a major sheddase of TNF-alpha and its receptors, essential for the generation of soluble, mature molecules. The regulation of the TACE activity by ethanol in vitro has been suggested recently. The alcohol abuse is a frequent problem among psoriasis patients. The aim of the study was to analyse the relationship between long-term alcohol consumption and the concentration of TACE in peripheral blood mononuclear cells (PBMC) and its substrate--soluble TNF-alpha receptor type 1 (sTNF-R1) in plasma in psoriasis patients.
The study has been conducted among 44 patients (aged 30-59 years) with early-onset, plaque-type psoriasis. Thirty-eight patients (aged 29-61 years) with other than psoriasis chronic dermatologic disorders were controls. The data on alcohol consumption during previous 10 years were obtained with a structured questionnaire. The severity of the disease was assessed using Psoriasis Area and Severity Index (PASI), and concentrations of TACE in PBMC lysate and sTNF-R1 in plasma was assessed with a quantitative sandwich enzyme immunoassay technique.
The TACE concentration correlated to that of sTNF-R1 (R = 0.52 in psoriasis patients and R = 0.56 in controls, P < 0.05). The concentrations of TACE were 2.62 +/- 0.32 ng/mL in patients and 1.29 +/- 0.25 ng/mL in controls (P < 0.05), and corresponding sTNF-R1 concentrations were 2.54 +/- 0.27 ng/mL and 1.79 +/- 0.14 ng/mL (P < 0.05), respectively. The concentrations of TACE and sTNF-R1 in patients correlated to the intensity of alcohol consumption (R = 0.56, and R = 0.52, P < 0.05, respectively) and were the highest in excessive drinking psoriasis patients (2.94 +/- 0.34 and 2.67 +/- 0.13 ng/mL).
The alcohol abuse may contribute to the increase of TACE expression in PBMC and also to the elevated plasma sTNF-R1 concentration in psoriasis patients.

[Show abstract][Hide abstract] ABSTRACT: The aim of the study was to assess plasma and scales levels of interleukin (IL) 18 collected from psoriatic patients with different disease activity. IL-18 concentrations were measured using an enzyme immunoassay in the plasma and scales of 34 patients with chronic plaque type psoriasis. IL-18 levels were analysed with respect to plasma-transforming growth factor beta1 (TGF-beta1), the disease duration and the duration of the present relapse, and psoriasis area and severity index (PASI). Plasma IL-18 concentration varied from 90 to 1300 pg ml-1 and means (368.2 +/- 42.4 pg ml-1) were significantly elevated in comparison with healthy controls (205.9 +/- 31.8 pg ml-1). The presence of IL-18 was also demonstrated in scales from skin lesions. Treatment caused a significant decrease of plasma IL-18 concentration to 250.2 +/- 13.8 pg ml-1. There was a significant correlation between plasma IL-18 levels and PASI values (r = 0.554). There was no correlation between IL-18 concentration in scales and PASI, between IL-18 concentrations in plasma and scales, and between plasma IL-18 and the disease duration or duration of present relapse. Plasma TGF-beta1 concentration demonstrated a significant correlation with PASI (r = 0.353), but not with IL-18 levels in plasma (r = 0.063) and scales (0.141). The sum of plasma levels of IL-18 and TGF-beta1 divided by the optimal coefficient demonstrated a statistically significant correlation with the highest r-value. The findings confirm an association between plasma IL-18 concentration and psoriasis severity. Moreover, it was shown that combined measurement of IL-18 and TGF-beta1 in plasma can be considered as a possible biomarker of psoriasis activity.
[Show abstract][Hide abstract] ABSTRACT: The aim of this study was to evaluate the effect of psoriasis treatment on plasma concentrations of metalloproteinase-1 (MMP-1) and tissue inhibitor of metalloproteinases-1 (TIMP-1) with respect to disease severity.
MMP-1 and TIMP-1 were measured using an enzyme immunoassay in plasma of 32 patients before and after topical treatment. Data were analysed with respect to baseline values of the Psoriasis Area and Severity Index (PASI).
Baseline plasma concentrations of both TIMP-1 and MMP-1 (1487 +/- 102 and 21.0 +/- 2.5 ng/mL, respectively) were significantly higher (P = 0.02 and 0.03, respectively) than normal. Both TIMP-1 and MMP-1 decreased significantly after completion of treatment to values similar to normal (1112 +/- 127 and 11.3 +/- 1.3 ng/mL, respectively). There was a significant positive correlation (r = 0.522) between baseline PASI and TIMP-1 values. Significant differences were observed between baseline TIMP-1 concentrations in groups with PASI < 15 and PASI > 20. Baseline values (1697 +/- 162 ng/mL) in patients with severe course of the disease (PASI > 20) were significantly elevated in comparison to normal values. Treatment caused a decrease in TIMP-1 plasma concentrations in all groups, but a significant difference was noted only in patients with pretreatment PASI > 20. Baseline MMP-1 concentrations exceeded significantly normal values only in patients with PASI < 15 (27.2 +/- 6.3 ng/mL) and 15-20 (18.4 +/- 1.4 ng/mL). Treatment caused a significant decrease in MMP-1-values in all groups to levels similar to normal.
Our results confirm the role of TIMP-1 and MMP-1 in the pathogenesis of psoriasis. Pretreatment plasma TIMP-1 increased whereas MMP-1 decreased in patients with a more severe course of the disease. However, successful treatment causes normalization of these plasma protein concentrations irrespective of psoriasis baseline activity.

[Show abstract][Hide abstract] ABSTRACT: Objective
Tumor 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.
[Show abstract][Hide abstract] ABSTRACT: To determine the increase in healing rate of venous ulcer in patients receiving a micronised purified flavonoid fraction (MPFF) as supplementation to standard local care.
Design: A randomised, open, controlled, multicentre study. Setting: Departments of Dermatology and University Outpatients Clinics. Patients: One hundred and forty patients with chronic venous insufficiency and venous ulcers. Intervention: Patients received standard compressive therapy plus external treatment alone or 2 tablets of MPFF daily in addition to the above treatment for 24 weeks. Main outcome measure: Healing of ulcers and their reduction in size after 24 weeks of treatment.
The percentage of patients whose ulcers healed completely was found to be markedly higher in those receiving MPFF in addition to standard external and compressive treatment than in those treated with conventional therapy alone (46.5% vs 27.5%; p<0.05. OR=2.3, 95% CI 1.1-4.6). Ulcers with diameters <3 cm were cured in 71% of patients in the MPFF group and in 50% of patients in the control group, whereas ulcers between 3 and 6 cm in diameter were cured in 60% and 32% of patients (p<0.05), respectively. The mean reduction in ulcer size was also found to be greater in patients treated with MPFF (80%) than in the control group (65%) (p<0.05). The cost-effectiveness ratio (cost per healed ulcer) in the MPFF group was 1026.2 compared with 1871.8 in the control group.
These results indicate that MPFF significantly improves the cure rate in patients with chronic venous insufficiency.

[Show abstract][Hide abstract] ABSTRACT: The aim of the study was evaluation of specific immune response against Borrelia afzelii in patients with erythema migrans, as a sign of an early stage of Lyme borreliosis. The study was performed in 42 patients, residents of Podlasie province, who were initially evaluated by indirect immunofluorescence assay as a seropositive for Borrelia burgdorferi sensu lato. Antibodies against particular antigens of B. afzelii were demonstrated using a Western-blot technique. Evaluation of results showed the most frequent prevalence of antibodies against 41 kDa antigen in majority of patients, which were predominantly of IgM class in patients with short-lasting lesions, and IgG class in patients with long-lasting lesions. Results of IgM blots were recognized as a positive in 26 patients, and IgG blots in 22 patients. Positive result in at least one class of antibodies was noted in 34 patients (81%), and in both classes in 14 (33%). IgM antibodies against 21 kDa antigen, and IgG antibodies against 43 kDa antigen were two fold more frequent in patients with short-lasting lesions. These results confirm the diagnostic usefulness of determination of antibodies against B. afzelii antigens in Poland. The most important for an early diagnosis can be simultaneous demonstration of IgM antibodies against 21 and 41 kDa antigens.

Conclusions: These results indicate that MPFF significantly improves the cure rate in patients with chronic venous insufficiency.
[Show abstract][Hide abstract] ABSTRACT: Because of the sexually transmitted diseases (STDs) epidemic in the former Soviet Union and the possibility of a rise in early syphilis and gonorrhoea in the eastern region of Poland it seemed important to calculate the incidence rates for early syphilis and gonorrhoea for 3 border regions (east, west and south) and the central part of the country in the last 10 years. In addition, data were analysed on patients and their sexual partners (from Poland and abroad), and the country where the contact took place obtained from 14 Provincial Skin-VD Out-Patients' Clinics of eastern Poland. The results from 1988/89 and 1996/97 were compared. It was shown that early syphilis morbidity significantly decreased in western and southern Poland, fell in the central part and rose in the east slightly. Gonorrhoea morbidity significantly decreased in all regions. However, the number of provinces with early syphilis and gonorrhoea incidence rates in the 1990s of the same value or higher than in the 1980s, or of the whole of Poland clearly increased in eastern and central regions. The early syphilis and gonorrhoea morbidity in east Poland in the 1990s in relation to 1980s was marked by significant increase in the percentage of the foreigners treated (12.2 vs 1.8, P<0.001 for early syphilis, and 10.0 vs 2.3, P<0.001 for gonorrhoea) and in sexual contacts with foreigners reported by Polish patients (23.7 vs 0.8, P<0.01 for early syphilis and 17.7 vs 4.3, P<0.01 for gonorrhoea). Of the foreign contacts reported in 1996/97 by early syphilis and gonorrhoea patients, 60.4% and 82.2%, respectively, were casual. Contact with foreigners took place, mainly, in the former Soviet Union. The study illustrates that there may be a danger of an increase in the incidence of syphilis and gonorrhoea in Poland due to the epidemics in the neighbouring countries.

[Show abstract][Hide abstract] ABSTRACT: Aim of the study was to evaluate the efficacy, tolerance and safety of treatment of leg ulcer with pentoxiphylline administered orally in daily dose of 1200 mg divided for 3 doses for six months. The study was carried out in 19 centres in Poland. The results of clinical and laboratory (HGB, WBC, PTL) examinations made before, during and after treatment were documented in individual case-records. Pentoxiphylline was administered to 184 patients (124 F and 60 M) aged 22-86 (mean-61.6) yrs. One hundred and thirty-five patients had non-arterial ulcers, 37-partly arterial and 12-arterial. The duration of the disease was 1 to 1620 (mean 158) weeks. Resting pain was reported by 131 patients. In 9 persons the treatment was stopped after 1-2 months; in 6 (3%) of them due to side effects. In 175 patients pentoxiphylline was administered as follows: 1200 mg daily for 6 months in 92 cases, 1200 mg daily for 2-5 months--in 58, 1200 mg daily for 3-5 months and 800 mg daily for next 1-3 months--in 12 cases, and 800 mg daily for 1-6 months--in 13 cases. In 161 (92%) cases a beneficial effect was achieved including complete healing of the ulcers in 79 (45%) or improvement in 82 (47%); in 14 (8%) there was no improvement. The resting pain was significantly reduced in 114 (87%) patients within 1-24 weeks and completely disappeared in 69 (53%) patients within 2-20 weeks of treatment. No significant abnormalities in the results of laboratory tests were found. Transient side effects of the therapy appeared in 11 patients but they did not require administration of the drug to be discontinued. The study showed that pentoxiphylline is a effective, well tolerated and safe drug in the treatment of leg ulcers.

[Show abstract][Hide abstract] ABSTRACT: A case-control study was conducted to evaluate the role of dietary selenium (Se) intake and the selenium nutritional status in the course of psoriasis. The cases studied were 30 psoriatic patients with a history of the disease no longer than 10 months and 29 psoriatics with the disease lasting at least 3 years, 24 other dermatological patients and 14 healthy subjects constituted 2 control groups matched to cases studied by sex and age. Se dietary intake was calculated from 24-hours dietary recall and Se status was assessed with plasma Se level as well as plasma and erythrocyte GSH-Px activity. Dietary Se intake was found to be correlated to erythrocyte GSH-Px (r = 0.50, p < 0.05). The selenium nutritional status seemed to be insufficient, especially in females with psoriasis of no longer than 10 months' duration and males with long-lasting psoriasis. In these males plasma and erythrocyte GSH-Px activity were inversely correlated to the severity of the disease (r = -0.64 and r = -0.41, p < 0.05, respectively). The results obtained suggest that Se dietary intake could be one of the contributing factors in the pathogenesis and course of psoriasis. Further studies are needed to explore this relationship.

[Show abstract][Hide abstract] ABSTRACT: Acrodermatitis chronica atrophicans (ACA) occurs mostly in Europe. Borrelia afzelii is considered to be responsible for this manifestation of Lyme borreliosis. The aim of the study was to observe the clinical features of the ACA and evaluate the specific immunological response to Borrelia afzelii. Nine patients from an endemic Lyme borreliosis region in northeastern Poland were studied. The serum samples were tested routinely with IFA and EIA and, following testing, with immunoblots using Borrelia afzelii antigens. ACA was located mainly on the skin of the arms, forearms, thighs and chest. The only extracutaneal manifestation of Lyme borreliosis was paresis of the brachial plexus observed in one patient. Analysis of the immunoblot-banding pattern revealed positive reactions in all patients against flagellar antigen (41 kDa). Interpretation of the immunoblots revealed positive IgG results in all cases and IgM in five of them. Concluding, ACA develops not only on the extremities, but also on the trunk. The immunoblot technique using Borrelia afzelii antigens is of value in the diagnosis of ACA.
[Show abstract][Hide abstract] ABSTRACT: The aim of the study was to evaluate erythema migrans (EM) prevalence and treatment in north-eastern Poland during the last 25 years. The material for the study consisted of data sent to the Department of Dermatology by physicians from fifteen regional out-patient clinics. They were collected according to specially prepared questionnaires. The data were analysed with respect to the total number of EM cases, patients' age, seasonal prevalence of the disease, dynamics of its prevalence and treatment methods in successive years. Of the 262,421 case histories, retrospectively analysed 1235 EM cases (0.4%) were found. The age of the patients varied from 4 to 78 years. The highest incidence was observed between August and October (57.7% of all cases). The annual number of cases increased from only a few, in the years 1969-76, to over 436 in 1993. Penicillin or erythromycin were preferred for the treatment of EM before 1981, tetracycline or ampicillin between 1982-90, and amoxicillin or doxycycline in the last three years. Our results showed a significant increase in the number of EM cases in the dermatological clinics of north-eastern Poland in recent years. The treatment of the disease applied at present, complies with the generally accepted guidelines.
