RESUMO

OBJECTIVE: The current study aimed to examine the psychiatric symptoms that can be seen in fibromyalgia (FM) patients, their attitudes toward seeking psychological help, and their concerns about stigma. Besides, it was investigated whether the stigma concerns that they may experience about receiving psychiatric treatment constitute an obstacle for patients to receive psychiatric treatment. SUBJECTS AND METHODS: This cross-sectional descriptive study was conducted between February and July 2020. Various seeking help were measured with Attitude Towards Seeking Psychological Help Scale-Short Form (ATSPPH-SF), Self-Stigma in the Process of Seeking Psychological Help Scale (SSPSPHS), Intention to Seek Psychological Help Inventory (ISPHI), and Social Stigma Due to Seeking Psychological Help Scale (SSDSPHS). FM symptoms of patients were measured with The Symptom Screening Questionnaire, Revised 90 Items (SCL-90-R). Quality-of-life parameters were measured with Fibromyalgia Impact Questionnaire (FIQ). RESULTS: Fibromyalgia patients had higher somatization (p=0.001), psychotism (p=0.045) and phobic anxiety (p=0.015) scores than controls. The ATSPPH-SF (p=0.002) and SSPSPHS (p=0.043) scale scores of the FM patients were higher than the controls. There was a significant positive correlation between FIQ and SSPSPHS (r=0.288, p=0.043) and SCL-90 overall (r=0.602, p<0.001) and all subscales scores. Patients with high active psychotic symptom levels had higher FM exposure scale scores and SCL-90 overall scores than those with low active psychotic symptom levels (p<0.001). CONCLUSIONS: The findings of this study showed that fibromyalgia patients have more somatization symptoms than healthy individuals, and as psychiatric symptoms increase in these individuals, their level of being affected by FM increases.

RESUMO

Systemic sclerosis (SSc) is an autoimmune connective tissue disease with multisystem involvement. An increased incidence of cancer in SSc patients compared with the general population has been reported in several reports. Our aims in this study were to determine the most common malignancies and to investigate the possible risk factors for the development of malignancy in patients with SSc. Three hundred forty SSc patients from 13 centers were included to the study. Data of the patients were obtained by evaluating their medical records retrospectively. A total of 340 patients with SSc were evaluated. Twenty-five of the patients had 19 different types of malignancy. Bladder cancer was the most common type of cancer with four patients and was followed by breast cancer with three patients, and cervix cancer and ovarian cancer with two patients each. Other types of cancers such as squamous cell skin cancer, adenocancer with an unknown origin, multiple myeloma, chronic myeloid leukemia, papillary thyroid cancer, larynx cancer, non-small cell lung cancer, follicular type non-Hodgkin lymphoma (NHL), endometrium cancer, colon cancer, uterus cancer, neuroendocrine tumor, glioblastoma multiforme, and soft tissue sarcoma were diagnosed in one patient each. The only cancer type that showed an association with cyclophosphamide dose was bladder carcinoma. Other malignancies did not show a correlation with age, sex, smoking, type and duration of the disease, autoantibodies, organ involvement, and dose and duration of cyclophosphamide therapy. Cancer may develop in any organ in patients with SSc. Continuous screening of the patients during a follow-up period is necessary for the early detection of the tumor development.

RESUMO

Rheumatoid arthritis (RA) is a major cause of adult chronic inflammatory arthritis and an autoimmune disease of unknown etiology in which the inflammatory pathology involves T cell activation. Genetic mutations in the Mediterranean fever (MEFV) gene, encoding pyrin, influence the severity of RA, but the underlying mechanisms are not completely understood. In this study, we investigated whether the full-length MEFV gene (MEFV-fl) and the exon 2-deleted splice isoform (MEFV-d2) expression are associated with or responsible for the clinical conditions of RA. This study include 47 patients with RA and 47 age- and gender-matched healthy controls. Quantitative real-time polymerase chain reaction analysis was performed to examine transcriptional changes in MEFV gene expression from peripheral blood samples. Reverse transcription-polymerase chain reaction of peripheral blood cells revealed the downregulation of MEFV-fl mRNA in non-treated patients compared with healthy controls and treated patients. MEFV-d2 expression was not different between groups. This is the first study to investigate the expression of MEFV transcript in RA. Deregulation of the MEFV gene is likely to result in uncontrolled inflammation as observed in RA. Therefore, downregulation of MEFV-fl may be involved in the pathogenesis of early-stage RA and treatment and may ameliorate MEFV-fl expression.

RESUMO

BACKGROUND: Scleroderma is a chronic inflammatory disease characterized by widespread fibrosis of the skin and the internal organs. Ghrelin is a polypeptide hormone produced by various tissues and inflammatory cells. In experimental studies, ghrelin has been shown to have anti-inflammatory and antioxidant effects, in addition to its metabolic actions. AIM: To evaluate the potential preventive effects of ghrelin on a mouse model of bleomycin (BLM)-induced scleroderma. METHODS: This study involved five groups of BALB/c mice (n = 7 in each group). Mice in the control group received 100 µL/day of phosphate-buffered saline (PBS) subcutaneously, while the other four groups were given 100 µg/day of BLM (dissolved in 100 µL PBS) subcutaneously. Three of the BLM-treated groups received intraperitoneal doses (10 ng/kg/day) of acylated, nonacylated or total ghrelin. Animals were killed at the end of the fourth week, and blood and tissue samples were collected for further analysis. Dermal thickness, serum levels of transforming growth factor-ß1, numbers of inflammatory cells on the dermal layer and numbers of α-smooth muscle actin-positive cells were determined. RESULTS: BLM increased dermal thickness, numbers of inflammatory cells on the dermal layer and activity of the myofibroblastic cells. Application of acylated, nonacylated and total ghrelin decreased the infiltration of inflammatory cells and the activity of the myofibroblastic cells, and reduced dermal fibrosis. CONCLUSIONS: Based on these results, it appears that ghrelin has an antifibrotic action, in addition to the anti-inflammatory and antioxidant effects that have been documented previously. The pathogenic and therapeutic roles of ghrelin in scleroderma should be evaluated by further studies.

RESUMO

BACKGROUND: T lymphocytes induce the transformation of fibroblasts into myofibroblasts, the main mediators of fibrogenesis. The inosine 5'-monophosphate dehydrogenase inhibitor mycophenolate mofetil (MMF) and the anti-CD25 monoclonal antibody daclizumab (DCZ) have been reported to suppress the proliferation of T lymphocytes. AIM: To evaluate the preventive effects of MMF and DCZ in early stages of bleomycin (BLM)-induced scleroderma. METHODS: This study involved five groups of Balb/c mice (n = 10 per group). Mice in four of the groups were injected subcutaneously (SC) with BLM [100 µg/day in 100 µL phosphate-buffered saline (PBS)] for 4 weeks; the remaining (control) group received only 100 µL PBS. Three of the BLM-treated groups also received either intraperitoneal MMF 50 or 150 mg/kg/day, or SC DCZ 100 µg/week. At the end of the fourth week, all mice were killed, and blood and tissue samples were obtained for further analysis. RESULTS: In the BLM-treated group, increases were seen in inflammatory-cell infiltration, α-smooth muscle actin-positive (α-SMA+) fibroblastic cell count, tissue hydroxyproline content, and dermal thickness. Dermal fibrosis was histopathologically prominent. In BLM-treated mice also given MMF or DCZ, inflammatory-cell infiltration, tissue hydroxyproline content and dermal thickness were decreased. In the MMF groups, decreases were also noted in α-SMA+ fibroblastic cell count. CONCLUSION: In this BLM-induced dermal fibrosis model, MMF and DCZ treatments prevented the development of dermal fibrosis. Further studies are needed to evaluate whether targeting T lymphocytes is effective in resolving pre-existing fibrosis in human scleroderma.

RESUMO

Obesity, characterized by hyperleptinemia and hypoghrelinemia, has become a major health problem all over the world and is associated with an increased risk of complications including insulin resistance, hypertension, dyslipidemia, diabetes mellitus and atherosclerosis. The use of the pancreatic lipase inhibitor Orlistat can help seriously overweight people to achieve and maintain weight loss. The aim of our study was to compare the serum leptin and ghrelin levels in obese subjects who take orlistat with those receiving only dietary treatment. Twenty-one obese patients and 10 control subjects participated. The obese patients were divided into two groups; one group (n=11) took orlistat (120 mg, 3 times daily) and received dietary treatment and the other (n=10) only received the dietary treatment. The study lasted twelve weeks. The concentrations of serum ghrelin, leptin, insulin and C-peptide, and routine biochemical parameters, were measured in both groups. The serum ghrelin level was higher in control (183+/-62 fmol/ml) than obese (59+/-30 fmol/ml) subjects while the plasma leptin level was lower in control (8.7+/-12 microg/L) than obese (36.7+/-19 microg/L) subjects (all p<0.001). BMI and the total blood cholesterol, LDL and triglyceride levels fell significantly after both orlistat and dietary treatment in the obese subjects (all p<0.01), and the plasma ghrelin level rose (p<0.01). The leptin level demonstrated the opposite trend in both groups but only the patients taking orlistat showed a significant change (p<0.05).Taken together, these results show that orlistat has no effect on body weight in obese subjects additional to that conferred by a non-pharmacological life-style intervention. We therefore conclude that weight lost rather than type of treatment might be more valuable in obesity.

RESUMO

OBJECTIVES: To evaluate the effects of etanercept and thalidomide in the mouse model of bleomycin-induced scleroderma (BLM-IS). METHODS: This study involved four groups (n = 8 mice in each group). Dermal sclerosis was induced by repeated subcutaneous injections of BLM (10 microg) for 4 weeks in BALB/c mice. Control group received only phosphate-buffered saline. The second group received only BLM; the third and fourth groups were also given an intraperitoneal injection of 100 microg etanercept or 150 mg/kg thalidomide, respectively. RESULTS: BLM increased serum TGF-beta1, tissue hydroxyproline levels and expression of alpha-smooth muscle actin (alpha-SMA), and dermal fibrosis was histopathologically prominent. Although thalidomide had no significant effect, etanercept caused decreases in levels of serum TGF-beta1, tissue hydroxyproline and number of alpha-SMA-positive cells. CONCLUSION: Inhibition of TNF-alpha with etanercept in BLM-IS was resulted in a significant reduction of the dermal sclerosis, collagen accumulation and the number of infiltrating myofibroblastic cells. TNF-alpha may play a key role in the progression of BLM-IS and TNF-alpha antagonists may be useful in the management of scleroderma.

RESUMO

Systemic lupus erythematosus (SLE) is a systemic, autoimmune disease. SLE patients are prone to infections, and their hospital admissions and mortality are most commonly associated with infections. Necrotizing fasciitis (NF) is a rare, life-threatening infection of the subcutaneous tissue. In this report, NF associated with Streptococcus pneumoniae (SPN) that developed within hours and resulted in death is presented in a 46-year-old female case who was recently diagnosed as SLE and did not receive any medication (steroid, immunosuppressive, etc.) except for etodolac. This case shows that SLE can generate predisposition to NF, and SPN can play a role in NF etiology.

RESUMO

It was reported that lipid peroxidation (LPO) products increase in rheumatoid arthritis (RA) patients and increased LPO products reduce many antioxidants. Lipid hydroperoxides (LOOHs) are byproduct of LPO. Paraoxonase (PON), arylesterase (ARE), free sulfhydryl (SH) groups, and ceruloplasmin (CP) are enzymes or proteins with antioxidant characteristics. This study aims to determine the levels of LOOHs and SH, and the activities of PON1, ARE, and CP in RA patients. The study included 47 active RA cases and 23 healthy volunteers. The levels of LOOHs and SH, and the activities of PON1, ARE, and CP were determined using appropriate methods. Student's t test and Spearman's correlation analysis methods were employed in the statistical evaluation. The level of LOOHs was found to be higher (p<0.001), while the level of SH and the activities of PON1, ARE, and CP were found to be lower (p<0.001, <0.001, <0.01, and <0.01, respectively) in the RA patient group when compared with the control group. There was a negative correlation between the level of LOOHs and the activity of PON1 in the patient group (r= -0.420 and p<0.01). The results of our study indicate increased oxidant and decreased antioxidant presence in RA patients. PON1 and ARE are known to have antiatherosclerotic effects in addition to their antioxidant characteristics. As the decrease in these antioxidants, resulting from increased oxidative stress in RA patients, development of atherosclerosis besides tissue injury seems inevitable.

RESUMO

The results of 75 patients with soft-tissue sarcomas treated by the combination of local surgical excision plus postoperative radiotherapy are reported. Thirty-five tumors were situated in the extremities, 32 in the trunk, and eight in the head and neck. Twenty-eight tumors were high grade, 33 intermediate and 14 low grade. Sixty-two patients had complete resections (wide or marginal) and 13 incomplete resections (intralesional). Radiation was administered with a shrinking-field technique (median total dose, 64 Gy; range, 50-78). Twenty-five patients developed local recurrence (33%). The 5-year local control rate was 67%. On univariate analysis, a tumor site other than extremity (p < 0.05), unfavorable histology (p < 0.01), and incomplete resection (p < 0.01) were poor risk factors for local recurrence. When multivariate analysis were performed, only incomplete resection (relative risk (RR) 7.2) remained a poor risk factor. The 5-year overall survival rate was 50.5% for the entire group. Following a univariate analysis of host tumor and treatment-related factors, a tumor site other than extremity (p < 0.05), high tumor grade (p < 0.01) unfavorable histology (p < 0.05), and incomplete tumor resection (p < 0.01) were found to significantly increase the risk of further tumor death. Multivariate analysis found high tumor grade (RR 5.6), and incomplete resection (RR 7) to be independent poor risk factors for survival.
