Fibromyalgia and menopause: an open study on postmenopausal hormone therapy.

BACKGROUND: Fibromyalgia women (FM) seems to get worse at menopause suggesting some influence of estrogens on its pathophysiology. We aimed to study the influence of postmenopausal hormone therapy (HT) in FM, the relationship with sleep and FM impact. METHODS: We analyzed prospectively 69 menopausal women, divided in two groups, FM group (FMG; N.=32) and comparison group (CG; N.=28) submitted to HT for twelve weeks (1.2 mg/g transdermal estradiol, 100 mg micronized natural progesterone oral/daily). Data on Utian Quality of Life Questionnaire (UQOL) and Pittsburgh Sleep Quality Index (PSQI) were obtained in both groups, at entrance and twelve weeks after HT. FM patients also completed the Fibromyalgia Impact Questionnaire - Revised (FIQ-R) and fibromyalgia severity (FS). RESULTS: FM patients improved significantly the FIQ-R (P=0.0001, median FIQ-R score 30% lower), mainly the severity of FM, assessed by FS (P<0.0001). Both groups had improved quality of life and sleep (UQOL: P=0.0001; P=0.001, PSQI: P<0.0001; P=0.007, respectively). Differences between first and second PSQI were greater for CG than for FMG (P=0.008). CONCLUSIONS: HT improving sleep and quality of life in both groups; it was a significant clinical improvement seen by FIQ and FS in FM patients. These changes characterize improvement of functional status and symptoms severity.

Association study involving polymorphisms in IL-6, IL-1RA, and CTLA4 genes and rheumatic heart disease in New Zealand population of Maori and Pacific ancestry.

INTRODUCTION: Rheumatic fever (RF) incidence among New Zealand (NZ) individuals of Polynesian (Maori and Pacific) ancestry remains among the highest in the world. Polymorphisms in the IL-6, IL1RN, and CTLA4 genes have been associated with RF, and their products are modulated by new medications. Confirmation of these previous associations could help guide clinical approaches. We aimed to test IL-6, IL-1RA (IL1RN), and CTLA4 functional SNPs in 204 rheumatic heart disease (RHD) patients and 116 controls of Maori and Pacific ancestry. MATERIAL AND METHOD: Self-reported ancestry of the eight great-grandparents defined ancestry of participants. Severity of carditis was classified according to the 2012 World Heart Federation guideline for the echocardiographic diagnosis of RHD. The IL-6 promoter rs1800797, IL1RN rs447713 and CTLA4 rs3087243 SNPs were genotyped by Taqman. Correlations were assessed by logistic regression analysis adjusting for gender and ancestry. RESULTS: The IL-6 rs1800797 variant was significantly associated with RHD with carriers of the GG genotype 6.09 (CI 1.23; 30.23) times more likely to develop RHD than the carriers of the AA genotype (P=0.027). No significant associations with RHD were found for the IL1RN rs447713 and CTLA4 rs3087243 SNPs. Patients carrying the G allele (GG plus AG genotype) for the IL1RN rs447713 SNP had 2.36 times (CI 1.00; 5.56) more severe carditis than those without this allele (the AA genotype) (P=0.049). CONCLUSION: The IL-6 promoter rs1800797 (-597G/A) SNP may influence susceptibility to RHD of people of Maori and Pacific ancestry living in NZ. The IL1RN rs447713 SNP may influence the severity of carditis in this population.

Decreased high-density lipoprotein cholesterol levels in polyarticular juvenile idiopathic arthritis.

OBJECTIVES: To investigate the prevalence of dyslipoproteinemia in a homogeneous cohort of polyarticular juvenile idiopathic arthritis patients. METHODS: Based on the National Cholesterol Education Program, fasting lipoprotein levels and risk levels for coronary artery disease were determined in 28 patients with polyarticular juvenile idiopathic arthritis. The exclusion criteria included diabetes, thyroid dysfunction, smoking, proteinuria, lipid-lowering drugs, and hormone/diuretic therapy. Disease activity, disease duration, and therapy with corticosteroids and/or chloroquine were defined at the time of lipid measurements. RESULTS: Dyslipoproteinemia was identified in 20 of the 28 (71%) patients with polyarticular juvenile idiopathic arthritis. The primary lipoprotein risk factor was decreased high-density lipoprotein cholesterol (57%), followed by elevated levels of low-density lipoprotein cholesterol (18%), triglycerides (14%), and total cholesterol (7%). The male patients had decreased high-density lipoprotein cholesterol levels than the female patients (p<0.05). The incidence of decreased high-density lipoprotein cholesterol levels did not seem to be affected by disease activity or therapy because the incidence was similar in patients with active or inactive disease, with or without corticosteroid use and with or without chloroquine use. In addition, the frequency of decreased high-density lipoprotein cholesterol levels was similar in patients with short (≤5 years) vs. long (>5 years) disease duration. CONCLUSIONS: Dyslipoproteinemia is highly prevalent in patients with polyarticular juvenile idiopathic arthritis and is primarily related to decreased high-density lipoprotein cholesterol levels; therefore, early intervention is essential.

Liver autoantibodies in patients with scleroderma.

Association between autoimmune liver diseases and scleroderma has been described. The purpose of this study was to study the prevalence of antimithocondrial antibody (AMA), antismooth muscle antibodies (SMA), and liver-kidney-microsomal (LKM-1) autoantibody in a cohort of 63 scleroderma patients and 100 healthy controls. The autoantibodies AMA, SMA, and LKM were determined by indirect immunofluorescence. Patients' charts were reviewed for demographic data, scleroderma form, and clinical and anti-nuclear antibody profile, aiming a comparison between patients with and without liver autoantibodies. Nine patients (14.3%) were positive for at least one of the liver autoantibodies; only one patient had both AMA and SMA positive. Antibody SMA was positive in 6.4% (4/63) patients; AMA was present in 9.52% (6/63) of them; none were positive to LKM-1. In the control group just one patient (1%) was SMA positive; the other autoantibodies were negative. There is an increased prevalence of liver autoantibodies in patients with scleroderma than in control population. These patients should be carefully followed for liver dysfunction.

COX-2, MMP-9, and Noguchi classification provide additional prognostic information about adenocarcinoma of the lung. A study of 117 patients from Brazil.

We report immunohistochemical staining results for cyclooxygenase (COX)-2 and matrix metalloproteinase (MMP)-9 in primary tumors of 117 patients with resected adenocarcinoma of the lung (median follow-up, 20 months). For COX-2, we graded the degree of tumor staining according to the sum of staining intensity and the proportion of cells staining. For MMP-9, we used morphometry to quantify cytoplasmic staining. We used the Cox proportional hazards model to analyze overall survival. With only 29 patients censored at last follow-up, after controlling for the effect of pathologic stage, staining for COX-2 and MMP-9 and subtype of tumor were related significantly to survival (P < 6 x 10(-5)). The effects of COX-2 and MMP-9 were opposite. Whereas any staining for COX-2 decreased the hazard and increased survival time, increased staining for MMP-9 increased the hazard and decreased survival time. The results also suggested that staining for COX-2 decreases with dedifferentiation. Our results suggest that staining for the combination of COX-2 and MMP-9 and categorizing tumors into papillary and nonpapillary types may provide important prognostic information for patients with resected adenocarcinoma of the lung; it is possible that these 3 variables could aid decisions about postoperative adjuvant treatment.
