Assessment of the anxiety and depression among patients with idiopathic pruritus ani.

INTRODUCTION: Pruritus ani is an unpleasant sensation that leads to scratching of the skin around the anus. It is a common symptom due to many systemic, dermatological, and proctological conditions. In the absence of evident organic origin of a disease, pruritus may be related to mental disorders as well as personality disorders. AIM: To assess the influence of pruritus on anxiety and depression in these patients. MATERIAL AND METHODS: The study involved 60 patients complaining of persistent pruritus ani. The study included people in which pruritus for organic reasons was ruled out. Tests were carried out to assess the level of depression and anxiety disorders. In addition, patients were asked to fill in the Questionnaire for the Descriptive Assessment of Pruritus and the 4-Item Itch Questionnaire by prof. Jacek Szepietowski. RESULTS: The cause of pruritus ani in the study groups has been shown to have a significant influence on the level of depressive symptoms. There was no such relationship for anxiety disorders. In the study group, there was no correlation of depressive-anxiety symptoms with the level of pruritus intensity and the frequency of pruritus. CONCLUSIONS: The presented data reveal the negative effect of pruritus ani on the psychological functioning of patients. Pruritus ani is characterized by moderate intensity of pruritus, but has a significant influence on the aggravation of depressive symptoms. It is important to look for the causes of this symptom, which can help to eliminate its intensity, improve the patients' mood, and thus improve their quality of life.

Correlation between the infrared thermogram and microvascular abnormalities of the nailfold in patients with systemic sclerosis.

INTRODUCTION: Systemic sclerosis (SSc) is a multisystemic disease with an extensive microvasculopathy. The gold standard for its investigation is nailfold videocapillaroscopy (NVC). AIM: To assess the value of thermography (IRT) for the assessment of microvasculopathy in patients with SSc. MATERIAL AND METHODS: Nineteen patients with limited cutaneous SSc were enrolled in the study. They underwent IRT imaging and NVC. An average temperature (Tavg) at the nailfold and a gradient of temperatures (ΔTavg) between the central metacarpus of the hand and the nailfold was determined for all fingers. NVC pictures were classified to capillaroscopic patterns according to Cutolo et al. system and they were analysed quantitatively to measure the density of capillaries and to calculate capillaroscopic skin ulcers risk index (CSURI) for each finger separately. RESULTS: There was only a moderate correlation (0.4 < r < 0.6) between thermographic parameters and density of capillaries in fingers II-V (r = 0.5; p < 0.001 for Tavg and r = -0.45; p < 0.001 for ΔTavg), but none in thumbs (r = 0.29; p = 0.089 for Tavg and r = -0.19; p = 0.275 for ΔTavg). Early pattern was associated with a significantly greater surface temperature (Tavg) of nailfolds and essentially milder ΔTavg in fingers II-V when compared to all other capillaroscopic patterns in fingers II-V. Surface temperature (Tavg) was significantly lower and ΔTavg was markedly more pronounced in fingers II-V with a greater risk of development of digital ulcers (DU) calculated by CSURI. CONCLUSIONS: Although IRT measurements correlate only moderately with density of capillaries, this technique seems to be substantial to determine the capillaroscopic pattern and to identify patients at greater risk of DU development.

The efficacy of antimalarial drugs in the therapy of selected forms of cicatricial alopecia.

INTRODUCTION: Frontal fibrosing alopecia (FFA) is primary lymphocytic cicatricial alopecia with a clinically characteristic progressive recession of the frontotemporal hairline, perifollicular erythema, as well as symptoms of itching and burning. It occurs mainly in postmenopausal women. FFA is considered as a subtype of lichen planopilaris (LPP). The treatment of those diseases is presently empirical. AIM: To define the efficacy of treating FFA and LPP with hydroxychloroquine. MATERIAL AND METHODS: We performed a retrospective analysis of 95 women, including 35 with FFA and 60 with LPP. We collected the relevant demographic and clinical data. The response to treatment with hydroxychloroquine was assessed using LPPAI. Also, adverse events were monitored. RESULTS: Treatment with hydroxychloroquine has a statistically significant effect on decreasing the disease activity after 6 and 12 months of therapy. The results of statistical tests do not confirm the existence of a relationship between age range and treatment efficacy. However, there is a correlation between the duration and efficacy of treatment (p < 0.05). CONCLUSIONS: Administration of hydroxychloroquine can be considered as one of the treatment methods for FFA and LPP in everyday clinical practice. The presented study is the first attempt at using hydroxychloroquine to treat such large patient groups for FFA and LPP. Hydroxychloroquine efficaciously alleviates the symptoms in LPP patients and gives maximum benefits in long-term therapy (12 months). The preliminary results obtained in the presented retrospective analysis should be confirmed in a randomized prospective clinical trial, which remains a future challenge for researchers.

Health-related quality of life and its influencing factors in adult patients with localized scleroderma - a cross-sectional study.

BACKGROUND: Localized Scleroderma (LoS) is an autoimmune connective tissue disease that affects skin and less commonly subcutaneous tissues. The illness occurs in children and adults, and may have a serious impact on health-related quality of life (HRQoL). The goal of this study was to explore what factors might deteriorate scores on HRQoL measures in adult LoS patients. METHODS: Detailed information on the demographic and clinical features of LoS patients was collected. The HRQoL was assessed using Skindex-29 and Short form 36 (SF-36) questionnaires. RESULTS: Thirty three women and seven men with LoS were enrolled. Female gender negatively influenced scores for the emotion subscale of Skindex-29. Multiple-factor linear regression analysis confirmed, as with single-factor analysis, that the causes of low SF-36 physical component score (PCS) were subjective symptoms (pruritus, pain, paresthesia), musculoskeletal manifestations and older age at the time of survey, while rural area of residence negatively affected the SF-36 mental component score. Additionally, single-factor analysis showed that the SF-36 PCS was related to the LoS cutaneous assessment tool (LoSCAT) summary score. CONCLUSIONS: Apart from a clinical presentations, sociodemographic characteristics, including older age, female gender and living conditions, may impair HRQoL of LoS patients. Further studies that will examine the role of these factors for physical and mental functioning of adults with LoS are needed.

Does adiponectin play a role in the pathogenesis of chronic spontaneous urticaria?

INTRODUCTION: Chronic spontaneous urticaria constitutes an interdisciplinary problem and its pathogenesis is still a subject of debate. Overweight and hyperlipidemia are supposed to be related to chronic spontaneous urticaria. Fatty tissue can be the source of adipokines. AIM OF THE STUDY: To assess the potential role of adiponectin in chronic spontaneous urticaria pathogenesis. MATERIAL AND METHODS: The study included 52 chronic spontaneous urticaria patients and 43 healthy controls. The patients were divided into two subgroups: patients with wheals only, and patients with urticaria and an accompanying angioedema. The adiponectin concentration was measured in all studied subjects. RESULTS: No statistically significant difference in adiponectin level was determined between the studied groups and subgroups. CONCLUSIONS: We are among the first to present the results of study to determine a possible role of adipokines in chronic spontaneous urticaria pathogenesis. We did not observe any difference in adiponectin level. In our opinion, it is necessary to conduct further analyses in this field.

MORPHEA AND LICHEN SCLEROSUS IN A PATIENT WITH HYPORTHYROIDISM.

Thyroid gland is one of the key organs regulating the metabolism of carbohydrates, proteins and fats. Its primary function is connected with increase of the metabolic conversion of the body. Skin lesions are often one of the first symptoms of hypothyroidism. In a 71-year-old patient, skin lesions in the form of thickened areas with severe hyperkeratosis first appeared 12 years before. Eight years before, the patient was diagnosed with hypothyroidism of unknown cause. Upon admission, lesions were observed in the trunk area, left arm and vulva. These lesions had the appearance of brownish spots with hyperkeratosis. Initially, they were localized on the trunk, then involving upper limbs and neck area with time. Significant progression was present in the back area. In the anogenital area, porcelain-white discolorations were observed. Laboratory examinations were normal. During hospital stay, iv. ceftriaxone at a dose of 2.0 g/day for 10 days and intramuscular injection of vitamin B6 were administered, along with 10% urea ointment for hyperkeratosis lesions as topical therapy. The patient had lesions in the form of skin induration and discoloration, with visible, very severe hyperkeratosis, which is not characteristic of changes of the scleroderma and lichen sclerosus type. These lesions caused diagnostic problems due to the atypical clinical appearance.

Frontal fibrosing alopecia: a disease that remains enigmatic.

Frontal fibrosing alopecia (FFA) is recognized to represent a generalized process of inflammatory scarring alopecia. Apart from the classic form affecting the frontal hairline, there are a range of disease manifestations involving loss of eyebrows and of eyelashes, loss of peripheral body hair, fibrosing alopecia in a pattern distribution, facial and extrafacial skin, mucous membrane, and nail involvement. Classic linear, diffuse "zigzag", pseudo "fringe sign", androgenetic alopecia-like, cockade-like, ophiasis-like and incomplete patterns are distinguished. The aetiology of FFA remains obscure, but a number of pathogenetic hypotheses and treatments to halt disease progression have been proposed.

Factors affecting the concentration of soluble tumour necrosis factor-α receptor type I in the blood serum of patients with localized scleroderma.

AIM: The aim of the study was to assess of sTNFαR1 concentration in the serum of patients with localized scleroderma (in comparison with a control group). MATERIAL AND METHODS: This was a prospective study. The patients with localized scleroderma were divided into two groups: 21 persons treated with PUVA therapy and 20 persons treated with procaine penicillin. In the case of the patients treated with intramuscularly administered procaine penicillin (dose: 2,400,000 IU/day), achievement of a total dose of at least 30 million IU/day was considered as the end of the therapy. In the group of patients treated with photochemotherapy, the single initial dose during a PUVA session was 0.5 J/cm2 and it was increased by 0.5 J/cm2 every other day to reach the maximum value of 10 J/cm2, depending on the clinical condition. The study involved three sessions a week. RESULTS: sTNFαR1 concentration in the serum of patients with localized scleroderma was significantly higher in comparison with the control group and correlated with the skin damage index. The difference in the determined particle level was higher in the group of patients undergoing photochemotherapy (median: 106.25 ng/ml) than in the group taking penicillin (median: 81.50 ng/ml). Patients treated with PUVA sessions demonstrated a greater decrease in sTNFαR1 concentration and an improvement of the clinical condition after therapy completion. CONCLUSIONS: The obtained results suggest a potential role of sTNFαR1 in the pathogenesis of localized scleroderma.

Evaluation of PSEN1 subunit of the γ-secretase gene in patients with psoriasis vulgaris: a pilot study.

INTRODUCTION: Psoriasis is a chronic autoimmune inflammatory disease, the prevalence of which is 1-3% in the Polish population. Genome testing using single nucleotide polymorphisms revealed more than 50 regions associated with the risk of psoriasis, and most of these genes are associated with the immune system. AIM: To assess the presence of PSEN1 subunits of the γ-secretase gene polymorphisms in patients with psoriasis and comparison of results with a healthy control group. MATERIAL AND METHODS: We used polymerase chain reaction - restriction fragment length polymorphism (PCR RFLP) method to assess polymorphisms. The starting material for analysis was peripheral blood obtained from the patient. RESULTS: PSEN1a-positivity was found in 2/52 (2.78%) of patients with psoriasis and 1/36 (3.85%) of healthy controls. PSEN1b positivity was seen in 3/52 (5.77%) of patients with psoriasis and 1/36 (3.85%) of control individuals. Only 3 patients with psoriasis but none of healthy volunteers had a presence of PSEN1c. Four patients were excluded from further statistical analysis. CONCLUSIONS: We have not shown a relationship between PSEN1 polymorphism and the clinical occurrence of psoriasis but now we start the assessment of other subunits of the γ-secretase gene - PSENEN and NCSTN.

An extended high-frequency ultrasound protocol for assessing and quantifying of inflammation and fibrosis in localized scleroderma.

BACKGROUND: Clinical characteristics of the lesions are used to identify activity and damage in localized scleroderma (LoS). For high-frequency ultrasound (HF-US), the features of active lesions were described. MATERIALS AND METHODS: Clinical signs of activity and damage in LoS lesions were assessed with the use of Localized Scleroderma Cutaneous Assessment Tool (LoSCAT) and HF-US by two examiners independently. All US images were obtained using a 20 MHz HF-US (DermaLab System, Cortex Technology, Hadsund, Denmark). The dermal thickness (DT) and echogenicity (intensity score, IS) of the LoS lesional dermis were measured in the area of each lesion with the highest score for erythema (ER), skin thickness (ST), and dermal atrophy (DAT). Measurements were compared to the site-matched unaffected skin. The relative difference of DT and IS values was calculated between each lesion and its normal control for comparison among different clinical scores for ER, ST, and DAT. RESULTS: A total of 92 lesions in 40 adult patients were examined with HF-US. Thirty one lesions were erythematous, 26 were in sclerosis, and 35 were in atrophy. A correlation between the clinical evaluation of the LoS lesions and US measurements was found. The sensitivity and specificity of HF-US were 97% and 90%, respectively. The positive predictive value was 83%, negative predictive value-98%. Interrater reliability was excellent for LoSCAT and HF-US findings. CONCLUSION: High-frequency ultrasound allows an accurate assessment of the inflammatory and fibrotic skin lesions in LoS.

The safety of isotretinoin treatment in patients with bone fractures.

Isotretinoin is widely applicable in dermatology, although it may develop severe side effects in the skeletal system. An intention of this review was to establish the safety of oral isotretinoin in patients with bone fractures. Both MEDLINE/Pubmed and SCOPUS databases were searched to investigate the influence of isotretinoin on the skeletal system. The drug shows a strong osteoporotic activity in rats whereas this effect is milder in humans. Biochemical markers of bone turnover remain unchanged except for serum calcium in patients receiving a high dose of isotretinoin. An excessive intake of vitamin A may impair functioning of vitamin D especially in people with a vitamin D deficiency, therefore a similar side effect may also occur in patients on isotretinoin treatment. We suggest reducing the use of isotretinoin after bone injury or continuing the treatment at low dosing with a concomitant correction of vitamin D and calcium status.

Localized Scleroderma Cutaneous Assessment Tool (LoSCAT) adapted for use in adult patients: report from an initial validation study.

BACKGROUND: Localized scleroderma (LoS) affects both children and adults and is associated with permanent functional and cosmetic impairment, and reduced quality of life predominating in adults. The Localized Scleroderma Cutaneous Assessment Tool (LoSCAT) is a clinical instrument designed to measure an activity and damage of LoS. It has been validated for use with pediatric LoS patients. This study assessed the validity and reliability of the LoSCAT adapted for use in adults. METHODS: Before the initiation of the study two examiners participated in an intensive training course carried out by an expert in LoS. Appendices describing each LoSCAT domain were prepared. Features determining disease activity and damage in adult LoS patients were identified to properly evaluate the physician (Phys) and patient (Pt) global assessment (GA) of disease activity (A)/severity (S) and damage (D), which were used to assess convergent validity of the LoSCAT. Correlations of physician- and patient-derivied measures with Skindex-29 were also analysed. RESULTS: The study included 40 adult LoS patients (33 females and 7 males) with different subtypes of LoS. Intra and inter-rater reliability of the LoSCAT was found to be excellent. Positive correlations were observed between the PhysGA-A, PhysGA-D, PtGA-A and the LoSCAT's domains, while no correlations between them and the PtGA-D were found. There were no relationships between LoSCAT's components and Skindex-29. CONCLUSIONS: Despite the LoSCAT is a reliable tool for an assessment of cutaneous lesions, additional health status instruments are necessary to a holistic approach to LoS in adults.

Randomized, controlled clinical pilot study of venous leg ulcers treated with using two types of shockwave therapy.

Background. Venous leg ulcers are difficult to heal wounds. The basis of their physiotherapeutic treatment is compression therapy. However, for many years, the search for additional or other methods to supplement the treatment of venous ulcers, which would shorten the duration of treatment, is underway. One of such methods is the shockwave therapy. Methods. The purpose of our study was to compare radial shockwave therapy (R-ESWT) with focused shockwave therapy (F-ESWT) in venous leg ulcers treatment. Patients were randomly assigned to tree groups. In the first group the radial shockwave therapy (0.17mJ/mm2, 100 impulses/cm2, 5 Hz), in the second group the focused shockwave therapy (0.173mJ/mm2, 100 impulses/cm2, 5 Hz) was used and in third group standard care was used. Patients in shockwave therapy groups were given 6 treatments at five-day intervals. Total area, circumference, Gilman index, maximum length and maximum width of ulcers were measured. The patients from the third group wet gauze dressing with saline and gently compressing elastic bandages were used (standard wound care SWC). Results. Analysis of the results shows that a complete cure of ulcers was achieved in 35% of patients who were treated with radial shockwave, 26% of patients with focused shockwave used. There is statistically significant difference between the standard care and radial shockwave therapy as well as between the standard care and focused shockwave therapy. There is no statistically significant difference between the use of radial and focused shockwave in the treatment of venous leg ulcers (p> 0.05). Conclusion. There is no statistically significant difference between the use of radial and focused shockwave in the treatment of venous leg ulcers. Treatment of venous leg ulcers with shockwaves is more effective than the standard wound care.

Shockwave therapy in selected soft tissue diseases: a literature review.

OBJECTIVE: The aim of our study is to present the current state of knowledge on the use of shockwave therapy (SWT) in the treatment of soft tissue wounds, by reviewing the available literature. METHOD: Medical databases were searched for articles using the keywords: 'shockwave AND wound healing', 'shockwave AND ulcers', 'shockwave AND burns', 'shockwave AND bedsores', 'shockwave AND diabetic foot ulcer', 'ESWT AND wound healing', 'shock wave AND diabetic gangrene'. RESULTS: A total of 14 scientific articles were included in the study which described the methodology of treatments and list the type of generator, physical parameters used during the procedure, number of treatments and the type of treated wounds. From these articles, 191 soft tissue wounds were analysed. CONCLUSION: Evidence from the articles analysed in this study suggests a beneficial effect of SWT to treat diabetic foot ulcers, venous leg ulcers, pressure ulcers and burns. SWT can be used in combination with standard treatment in soft tissue wounds.

Associations between site of skin lesions and depression, social anxiety, body-related emotions and feelings of stigmatization in psoriasis patients.

INTRODUCTION: Research has demonstrated a link between psoriasis and a multitude of psychological impairments; however, relatively few studies have examined the importance of site of skin lesions for negative psychological outcomes in psoriasis patients. AIM: To investigate relationships between anatomical location of psoriatic lesions and experiences of stigmatization, negative emotional attitude towards the body, depression and social anxiety. MATERIAL AND METHODS: Adult psoriasis patients (N = 193) completed the Stigmatization Scale, the Body Emotions Scale, the Beck Depression Inventory and the Social Anxiety Questionnaire. The body surface area index was used to assess the location and extent of psoriasis. RESULTS: Feelings of stigmatization were found to be most closely related to the presence of psoriatic lesions on the chest, and the arms and hands. Higher levels of social anxiety were found to be most closely related to the location of psoriatic lesions on the head and neck. Negative emotional attitude towards the body was found to be most closely related to the location of psoriatic lesions on the arms and hands, and on the head and neck. Higher levels of depressive symptoms were most closely related to the presence of psoriatic lesions on the head and neck, the arms and hands, and the genital area. CONCLUSIONS: The presence of psoriatic lesions on the head, neck, and chest, and also on the arms and hands and the genital area, should alert clinicians to a higher risk of psychological impairments. This may help to better recognize and prevent cumulative life course impairment.

Effect of adalimumab on the expression of genes encoding TNF-α signal paths in skin fibroblasts in vitro.

INTRODUCTION: Tumour necrosis factor (TNF-α) is one of the main cytokines participating in inflammation and immune response. Biological effects of the cytokine action, mediated by two receptors: TNFRSF1A and TNFRSF1B involve activation of many signal paths, thus change the transcription activity of many genes. The mechanism of action of an anti-TNF medicine consists in blocking TNF-α though preventing activation of signal paths. AIM: To single out mRNA and microRNA genes relating to TNF-α signal paths, the expression of which could indicate sensitivity of cells to the medicine in question. MATERIAL AND METHODS: The material used in the research consisted in the cell line of regular human skin fibroblasts NHDF (CC-2511 Lonza, Basel, Switzerland) exposed to adalimumab with a concentration of 8.00 µg/ml of the medium for 2, 8 and 24 h, compared with the control material, i.e. non-stimulated cells. Molecular analysis was performed using the oligonucleotide expressive micro-matrices technology HG-U133A, miRNA 2.0 Array micro-matrices and RTqPCR. RESULTS: mRNA: BIRC5, MAP3K4, ZFAND5, JUN differentiate cells exposed to the anti-TNF medicine, regardless of the time of cell/medicine incubation. TNF-α transcription activity is reduced during exposure of NHDF cells to adalimumab. miRNA regulating transcription activity of the said 4 mRNA and miRNA related to TNF-α and its receptors was also singled out. CONCLUSIONS: It was ascertained that adalimumab has therapeutic potential and affects genes engaged in signal paths activated by TNF-α. The results indicate the TNF-α usefulness as the molecular, supplementary marker in diagnostics and control of treatment effects.

The correlation between serum E-selectin levels and soluble interleukin-2 receptors with relation to disease activity in localized scleroderma.

INTRODUCTION: Scleroderma is a chronic connective tissue disease resulting in fibrosis. AIM: The aim of the study was to determine the connection between sE-selectin and sIL-2R and the severity of skin lesions in various subtypes of LoS. Evaluation of disease severity, the location of skin lesions, the duration of symptoms and disease activity were assessed in relation to the three different LoS subtypes in patients with localized scleroderma. MATERIAL AND METHODS: The study included 42 patients with localized scleroderma and the control group consisted of 41 healthy subjects. All patients in the LoS study group had a confirmed diagnosis via skin biopsy and underwent serology testing for sE-selectin and sIL-2R concentrations by enzyme-linked immunosorbent assay (ELISA). RESULTS: Significantly higher levels of sE-selectin and sIL-2R were observed in the LoS study group when compared with the control group (p < 0.001). The analysis showed a result close to statistical significance (p = 0.058) between sE-selectin concentration during the time of active disease in the LoS study group. The highest concentrations of sE-selectin and sIL-2R were observed in patients with the generalized subtype of LoS. A positive, statistically significant, curvilinear relationship was shown amid the modified Localized Skin Severity Index (mLoSSI) and sE-selectin and sIL-2R concentrations in the LoS study group. CONCLUSIONS: Concentrations of the circulating form of sE-selectin appear to be an adequate marker of the endothelial function, positively correlating with the severity of the disease. The proven correlation of sIL-2R concentrations with the severity of the disease indicates that it is a valuable prognostic factor for predicting the impending course of the disease.

Comparison of ultrasound therapy and radial shock wave therapy in the treatment of venous leg ulcers - clinical, pilot study.

INTRODUCTION: Venous insufficiency and venous leg ulcers each year affect more and more people, especially in developed countries. The challenge of our time is to find an effective method of treating venous leg ulcers, which will further shorten treatment time and reduce the cost of treatment. AIM: To compare the effects of treating venous leg ulcers using ultrasound therapy, radial shock wave therapy and standard care. MATERIAL AND METHODS: Group A consisted of 17 patients. Patients were treated with ultrasound therapy US power density 0.5 W/cm2, pulsed wave with a duty cycle of 1/5, and 1 MHz frequency. Group B consisted of 17 patients. Patients were treated with the radial shock wave R-ESWT using surface energy density 0.17 mJ/mm2, 100 impulses/cm2, frequency of 5 Hz and a pressure of 0.2 MPa. Group C (control group) consisted of 17 patients. Patients in this group received standard care: gauze dressing saturated in 0.9% sodium chloride and elastic bandages changed daily for 4 weeks. RESULTS: Ultrasound therapy with 1 MHz and energy power density 0.5 W/cm2 for 4 weeks resulted in an average reduction of 68% of the area of ulceration. We used for venous leg ulcers 4-week treatment with radial shock wave therapy resulting in a 38% mean percentage reduction of the ulceration area. Standard care reduces the area of ulceration by only 16%. CONCLUSIONS: The use of ultrasound therapy for the treatment of venous leg ulcers is more effective than the use of radial shock wave therapy or standard care alone.

Variances in the mRNA expression profile of TGF-ß1-3 isoforms and its TGF-ßRI-III receptors during cyclosporin a treatment of psoriatic patients.

INTRODUCTION: Psoriasis is a chronic, immunologic, multi-factor inflammatory skin disease, strongly associated with a higher level of a number of cytokines, such as isoforms of transforming growth factor ß (TGF-ß1-3) and its receptors (TGF-ßRI-III). One of the most popular and important drugs used to treat this disease is cyclosporin A (CsA). AIM: The aim of this study was to investigate the expression of genes encoding the transforming growth factor (TGF)-ß isoforms and receptors of the cytokine TGF-ßRs in psoriatic patients during an 84-day long observation of the effects of cyclosporin A therapy. It made an attempt to determine the usefulness of testing mRNA expression of TGF-ß1-3 and its receptors TGF-ßRI-III as the supplementary molecular markers of lost sensitivity to the medicine. MATERIAL AND METHODS: The study group consisted of 32 patients with psoriasis (20 men and 12 women) treated with cyclosporin A. The changes in expression patterns of TGF-ß1-3 and TGF-ßRI-III were performed by real-time quantitative reverse transcription PCR (RTqPCR). RESULTS: The expression of TGF-ß1-3 and TGF-ßRI-III were detected in the whole period of therapy with CsA. Changes in transcriptional activities of TGF-ß1-3 and TGF-ßRI-III during pharmacotherapy were observed. Differences in the expression of these genes were found before and after 42 and 84 days of using CsA. CONCLUSIONS: The changes in expression profiles of TGF-ß1-3 and TGF-ßRI-III during CsA therapy can be a useful molecular marker of lost sensitivity to the medicine.

Newer treatments of psoriasis regarding IL-23 inhibitors, phosphodiesterase 4 inhibitors, and Janus kinase inhibitors.

The rapid progress of genetic engineering furthermore opens up new prospects in the therapy of this difficult-to-treat disease. IL-23 inhibitors, phosphodiesterase 4 (PDE4) inhibitors, and Janus kinase (JAK) inhibitors are currently encouraging further research. Two drugs which are IL-23 inhibitors are now in phase III of clinical trials. The aim of the action of both drugs is selective IL-23 inhibition by targeting the p19 subunit. Guselkumab is a fully human monoclonal antibody. Tildrakizumab is a humanized monoclonal antibody, which also belongs to IgG class and is targeted to subunit p19 of interleukin 23 (IL-23). Phosphodiesterase inhibitors exert an anti-inflammatory action and their most common group is the PDE4 family. PDE4 inhibits cAMP, which reduces the inflammatory response of the pathway of Th helper lymphocytes, Th17, and type 1 interferon which modulates the production of anti-inflammatory cytokines such as IL-10 interleukins. The Janus kinase (JAK) signaling pathway plays an important role in the immunopathogenesis of psoriasis. Tofacitinib suppresses the expression of IL-23, IL-17A, IL-17F, and IL-22 receptors during the stimulation of lymphocytes. Ruxolitinib is a selective inhibitor of JAK1 and JAK2 kinases and the JAK-STAT signaling pathway. This article is a review of the aforementioned drugs as described in the latest available literature.
