Concentrations of metalloproteinase-1 in patients with morphea treated with phototherapy: a preliminary study.

Introduction: Morphea (localized scleroderma) is a rare, chronic, inflammatory connective tissue disease, characterized by immune system dysfunction, vasculopathy and skin fibrosis. One of the most effective treatments is phototherapy. Phototherapy has been found to be effective in treating localized scleroderma by inducing the expression of metalloproteinase-1. Aim: To compare the concentrations of metalloproteinase (MMP-1) before psoralen and ultraviolet A (PUVA) and ultraviolet A1 (UVA1) treatments in the serum of patients with morphea. Material and methods: The observational study was conducted in one research centre and included patients with generalised morphea who were treated with PUVA and UVA1 phototherapies. The mean age of all morphea patients included in the study was 55.7 years. The levels of MMP-1 were examined by ELISA (The Biorbyt Human MMP-1 ELISA - Enzyme-Linked Immunosorbent Assay). Results: The study showed that patients treated with PUVA and UVA1 had an improvement based on clinical measures, resulting in a reduction of clinical score. However, we did not observe statistically significant differences in MMP-1 concentrations before and after treatment. Limitations: The study sample was relatively small. Further studies on a larger group of patients would be beneficial. Conclusions: Our data suggest that there is a possible correlation between MMP-1 concentrations and phototherapy. MMP-1 levels were found to be increased following phototherapy treatment, which may suggest a correlation with better response to treatment in patients with morphea. However, further research is needed.

The microbiome of the human skin and its variability in psoriasis and atopic dermatitis.

The human organism is inhabited by very diverse microorganisms, which constitute the so-called human microbiome and are necessary for the proper functioning of the macroorganism. The correct microbiome ensures homeostasis of the body. A disturbance in its homeostasis leads to dysbiosis. Such deviations may also be related to the development of inflammatory skin diseases, including atopic dermatitis and psoriasis. This review aims to analyse the most current published data on the microbiome of the human skin and examine its role in cutaneous skin diseases, such as atopic dermatitis and psoriasis. This review was compiled by collaborating dermatologists specializing in atopic dermatitis and psoriasis. A comprehensive review of current literature was done using PubMed and limited to relevant case reports and original papers on the skin microbiome in atopic dermatitis and/or psoriasis. It has not been yet established whether changes in the microbiome are the cause or consequence of disease (atopic dermatitis/psoriasis). However, it was found that in the cases where pathological microflora predominated, an intensification of lesion severity is observed, while with clinical improvement, commensal microflora is restored. Modification of the composition of the microflora may lead to changes in the activation of the immune system and eventually to the development of inflammatory diseases. Adverse effects on the microbiome may include antibiotics, poor diet, stress and adverse environmental conditions. However, more research is needed to identify exact details and mechanisms.

Differences in the psychological and hormonal presentation of lean and obese patients with polycystic ovary syndrome.

BACKGROUND: Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders found in women of reproductive age. Differences in hormonal and metabolic profiles are observed in groups of patients with normal and elevated BMI. Cause of disturbances observed in the two groups of patients with PCOS is analyzed. The aim of the study is to assess whether psychological parameters of lean and obese patients with PCOS are comparably significantly different and whether there is a correlation between these characteristics and the concentration of various hormones. PARTICIPANTS AND PROCEDURES: The study consisted of 20 patients with diagnosed polycystic ovary syndrome and 20 healthy women of similar age. Both groups were stratified according to BMI. Specific psychological parameters and hormones were estimated in all patients. RESULTS: In our study, we found that patients with BMI <25 represented personality traits associated with lower resistance to stress. We also observed significantly higher ACTH levels in the same group as compared to patients with BMI >25. A correlation between plasma ghrelin and the severity of anxiety experienced by test subjects was also observed. CONCLUSION: The type of personality and emotional disorders in lean PCOS patients may lead to the activation of the hypothalamic-pituitary-adrenal (HPA) axis and disturbences in hypothalamic-pituitary-ovary (HPO) axis. The results suggest participation of primary hypothalamic dysfunction in the pathogenesis of PCOS in patients with specific fenotype. Ghrelin is a hormone that may affect the symptoms of PCOS in lean patients. Psychological therapy should be considered as a permanent element in the therapeutic plan provided to PCOS patients.

Amiodarone-induced thyrotoxicosis in a case of Eisenmenger's syndrome.

Eisenmenger's syndrome is a condition due to any congenital heart defect with an intracardiac left-to-right communication that leads to pulmonary hypertension with reversed right-to-left blood flow and secondary cyanosis. The main complications of Eisenmenger's syndrome are heart failure and arrhythmias. Amiodarone, the drug of choice for arrhythmia treatment in such patients, can cause a number of complications, including amiodarone induced thyrotoxicosis (AIT). Hereby, we present a 41-year-old patient with Eisenmenger's syndrome who developed AIT and was successfully treated with radioactive iodine therapy. The patient had an accompanying heart failure and had been treated with amiodarone due to chronic atrial fibrillation. Twenty months later he developed an AIT for which was treated with 814 MBq (22 mCi) radioactive iodine. Since 7 weeks later only a slight decline in thyroid hormones was observed, the patient was received a transient treatment with methimazole, which had to be withdrawn soon due to severe leucopenia. Because of the need to maintain amiodarone, a second ablative radioactive iodine dose was administered leading to complete clinical remission. In conclusion, this case demonstrates that even though amiodarone reduces iodine uptake to a very low level, the therapy with radioactive iodine can be still effective if it is given in a repeated dose to patients who require continuation of amiodarone.

The Intestinal and Skin Microbiome in Patients with Atopic Dermatitis and Their Influence on the Course of the Disease: A Literature Review.

Bacteria inhabiting the digestive tract are responsible for our health. The microbiome is essential for the development of the immune system and homeostasis of the body. Maintaining homeostasis is very important, but also extremely complicated. The gut microbiome is related to the skin microbiome. It can therefore be assumed that changes in the microbes inhabiting the skin are greatly influenced by the bacteria living in the intestines. Changes in the composition and function of microbes (dysbiosis in the skin and intestines) have recently been linked to changes in the immune response and the development of skin diseases, including atopic dermatitis (AD). This review was compiled by collaborating Dermatologists specializing in atopic dermatitis and psoriasis. A comprehensive review of the current literature was performed using PubMed and limited to relevant case reports and original papers on the skin microbiome in atopic dermatitis. The inclusion criterion was that the paper was published in a peer-reviewed journal in the last 10 years (2012-2022). No limitations on the language of the publication or the type of study were made. It has been shown that any rapid changes in the composition of the microflora may be associated with the appearance of clinical signs and symptoms of the disease. Various studies have proven that the microbiome of many systems (including the intestines) may have a significant impact on the development of the inflammatory process within the skin in the course of AD. It has been shown that an early interaction between the microbiome and immune system may result in a noticeable delay in the onset of atopic diseases. It seems to be of high importance for physicians to understand the role of the microbiome in AD, not only from the pathophysiological standpoint but also in terms of the complex treatment that is required. Perhaps young children diagnosed with AD present specific characteristics of the intestinal microflora. This might be related to the early introduction of antibiotics and dietary manipulations in breastfeeding mothers in the early childhood of AD patients. It is most likely related to the abuse of antibiotics from the first days of life.

Serological Evidence of Borrelia burgdorferi in Patients with Morphea from West-Central Poland: An Original Paper and Review of Literature.

Morphea (localized scleroderma) is an inflammatory connective tissue disease. Borrelia burgdorferi, as a causative factor, has been discussed controversially. The aim of this original study was to evaluate the frequency of IgM and IgG classes of anti-Borrelia antibodies in groups of morphea and psoriasis patients using the traditional ELISA method. Blood samples of 82 patients with morphea and 112 patients with psoriasis vulgaris were examined for the presence of IgM and IgG classes of anti-Borrelia antibodies (ELISA). IgM and IgG classes of anti-Borrelia antibodies were detected in 4% of blood samples taken from morphea patients, while 4.5% of blood samples from patients with psoriasis vulgaris. There is one major limitation in this study that could be addressed in future research. First, the study focused on the determination of IgM and IgG classes of anti-Borrelia antibodies as a risk factor for morphea, but other infectious agents also require further testing, such as Hepatitis B, Hepatitis C, and other viral or bacterial infections. The results of this study showed no significant relationship between Borrelia infection and morphea. Detection of IgM and IgG classes of anti-Borrelia antibodies is not recommended for routine diagnostics of patients with morphea at this time.

Thyroid lesions in patients with acromegaly - case-control study and update to the meta-analysis.

INTRODUCTION: Acromegaly results from oversecretion of growth hormone and subsequently insulin growth factor-1. According to some authors, the disease can cause increased prevalence of nodular goitre and thyroid cancer (TC). However, the number of studies comparing acromegalic patients with control groups is low. We aimed to assess the prevalence of thyroid lesions in patients with acromegaly in comparison to an age- and sex-matched control group and to update the meta-analysis previously performed in our department by the same authors. MATERIAL AND METHODS: We searched medical documentation of patients with acromegaly treated in our department between 2003 and 2013. The prevalence of thyroid abnormalities was compared with the group of patients with hormonally inactive adrenal incidentalomas. To perform the meta-analytic part of the paper we also searched ten databases to find relevant papers. RESULTS: Two hundred and five patients with acromegaly and 184 patients with incidentalomas were included. Any thyroid lesions were present in 77.6% of patients with acromegaly vs. 63.0% with incidentalomas (p = 0.002), multinodular goitre - 66.8% vs. 47.8% (p = 0.0002), and TC- 5.4% vs. 2.7% (p = 0.21) respectively. For thyroid lesions the pooled odds ratio (OR) was 3.1 (95% confidence interval [CI] 1.8-5.5), and for TCs the OR was 4.5 (95% CI 1.9-10.3). CONCLUSIONS: According to our results thyroid lesions were significantly more common in patients with acromegaly; in case of TC the difference was not significant. The updated meta-analysis showed significantly increased prevalence of both disorders. In conclusion, systematic thyroid examination should be an important part of follow-up in case of acromegalic patients. (Endokrynol Pol 2017; 68 (1): 2-6).

Inhibitors of phosphodiesterase 4 (PDE 4): A new therapeutic option in the treatment of psoriasis vulgaris and psoriatic arthritis.

Psoriasis vulgaris and psoriatic arthritis are inflammatory diseases in which inflammation and sustained inducing lesions result from immune disorders associated with overactivity of T cells that produce multiple proinflammatory cytokines, including tumor necrosis factor alpha (TNF-α) and interleukin (IL): IL-2, IL-12, IL-17, IL-22 or IL-23. Modern treatment of these diseases is focused on reducing the inflammatory process responsible for the development of the disease. In recent years, the treatment of psoriasis is developing at a dynamic rate. Such therapeutic advances are contributed to the possibility of patient therapy through the use of some registered biologic agents, such as TNF-α inhibitors (infliximab, etanercept and adalimumab), and an inhibitor of the p40 subunit common to IL-12 and IL-23 (ustekinumab). In addition to the already registered medications for the indications mentioned above, there is a large group of preparations that are currently undergoing clinical trials in Europe, Canada and the United States, which provides hopes of therapy efficacy and safety.

Emotional functions in transsexuals after the first step in physical transformation.

Transsexuals have to face multiple medical, social and bureaucratic problems. These problems are not only encountered before the transformation, but also during and after medical procedures. In the search for improvement of transsexual individuals' quality of life during therapy, it seems desirable to supplement hormonal treatments with psychological explorations. This study was conducted with the aim of defining emotional conditions and included 28 transsexual female-to-male (F/M) patients and two gender-divided control groups (males and females) of similar age. The following psychometric scales were used: CECS (Courtauld Emotional Control Scale constructed by M. Watson and S. Greer in the Polish Adaptation by Z. Juczynski), ISCL (the Polish Adaptation of the State-Trait Anxiety Inventory for Adults by T. Sosnowski), and GSES (the Polish Adaptation of the R. Schwarzer, M. Jerusalem Generalized Self-Efficacy Scaleby Z. Juczynski and K. Wrzesniewski). Transsexual F/M patients appeared very similar to males in the male control group in terms of their subjective selfefficacy and state-trait anxiety, while their subjective belief of anxiety and fear control was more comparable to that of the female controls. It was also found to be statistically significantly lower than in the male controls.

The usefulness of standardized uptake value in differentiation between benign and malignant thyroid lesions detected incidentally in 18F-FDG PET/CT examination.

INTRODUCTION: In the last decade, (18)F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET and PET/CT) has become one of the major diagnostic tools used in oncology. A significant number of patients who undergo this procedure, due to non-thyroidal reasons, present incidental uptake of (18F-FDG) in the thyroid. The aim of the study was to compare the SUVmax (standardized uptake value) of thyroid focal lesions, which were incidentally found on PET/CT, in relation to the results of thyroid fine-needle aspiration biopsy (FNAB) and/or histopathological evaluation. MATERIALS AND METHODS: Patients referred for PET/CT examination, due to non-thyroidal illness, presented focal 18F-FDG uptake in the thyroid and were advised to undergo ultrasonography (US), hormonal evaluation, FNAB and/or total thyroidectomy at our institution. RESULTS: 6614 PET/CT examinations performed in 5520 patients were analyzed. Of the 122 patients with focal thyroid 18F-FDG activity, 82 patients (67.2%) underwent further thyroid evaluation using FNAB. Benign lesions were diagnosed in 46 patients, malignant - in 19 patients (confirmed by post-surgical histopathology), while 17 patients had inconclusive results of cytological assessment. Mean SUVmax of benign lesions was 3.2±2.8 (median = 2.4), while the mean SUVmax value for malignant lesions was 7.1±8.2 (median = 3.5). The risk of malignancy was 16.7% for lesions with a SUVmax under 3, 43.8% for lesions with a SUVmax between 3 and 6, and 54.6% for lesions with a SUVmax over 6. In the group of malignant lesions, a positive correlation between the lesion's diameter and SUVmax was observed (p = 0.03, r = 0.57). CONCLUSIONS: Subjects with incidental focal uptake of 18F-FDG in thyroid are at a high risk of thyroid malignancy. A high value of SUVmax further increases the risk of malignancy, indicating the necessity for further cytological or histological evaluation. However, as SUVmax correlated with the diameter of malignant lesions, small lesions with focal uptake of 18F-FDG should be interpreted cautiously.
