- Creatine Supplementation in Fibromyalgia: A Randomized, Double-Blind, Placebo-Controlled Trial(2013) ALVES, Christiano R. R.; SANTIAGO, Bianca M.; LIMA, Fernanda R.; OTADUY, Maria C. G.; CALICH, Ana Luisa; TRITTO, Aline C. C.; PINTO, Ana Lucia de Sa; ROSCHEL, Hamilton; LEITE, Claudia C.; BENATTI, Fabiana B.; BONFA, Eloisa; GUALANO, BrunoObjective. To investigate the efficacy and safety of creatine supplementation in fibromyalgia patients. Methods. A 16-week, randomized, double-blind, placebo-controlled, parallel-group trial was conducted. Fibromyalgia patients were randomly assigned to receive either creatine monohydrate or placebo in a double-blind manner. The patients were evaluated at baseline and after 16 weeks. Muscle function, aerobic conditioning, cognitive function, quality of sleep, quality of life, kidney function, and adverse events were assessed. Muscle phosphorylcreatine content was measured through P-31 magnetic resonance spectroscopy. Results. After the intervention, the creatine group presented higher muscle phosphorylcreatine content when compared with the placebo group (+80.3% versus -2.7%; P = 0.04). Furthermore, the creatine group presented greater muscle strength than the placebo group in the leg press and chest press exercises (+9.8% and +1.2% for creatine versus -0.5% and -7.2% for placebo, respectively; P = 0.02 and P = 0.002, respectively). Isometric strength was greater in the creatine group than in the placebo group (+6.4% versus -3.2%; P = 0.007). However, no general changes were observed in aerobic conditioning, pain, cognitive function, quality of sleep, and quality of life. Food intake remained unaltered and no side effects were reported. Conclusion. Creatine supplementation increased intramuscular phosphorylcreatine content and improved lower- and upper-body muscle function, with minor changes in other fibromyalgia features. These findings introduce creatine supplementation as a useful dietary intervention to improve muscle function in fibromyalgia patients.

G.; BONFIGLIOLI, Karina Rossi; VIANA, Vilma S.; CARVALHO, Jozelio F.; SILVA, Clovis Artur; BONFA, EloisaBackground/Purpose: There are scarce data suggesting that pan-demic influenza vaccination may induce antiphospholipid (APL) autoan- tibodies in inflammatory rheumatic diseases, particularly in systemic lupus erythematosus patients. However, there is no study evaluating the APL autoantibodies induction in primary antiphospholipid syndrome (PAPS) patients. The objective was to perform short and long-term evaluations of a large panel of APL autoantibodies following pandemic influenza A/H1N1 non-adjuvant vaccine in PAPS patients and healthy controls. Lupus specific antibodies were also investigated in these patients. Methods: Forty-five PAPS patients (Sapporo criteria) and 33 healthy controls were vaccinated with monovalent, inactivated H1N1 vaccine (Butantan Institute/Sanofi Pasteur, São Paulo, Brazil). They were prospec-tively assessed at pre-vaccination, 3 weeks and 6 months after vaccination. APL autoantibodies were determined by an enzyme-linked immunosor-bent assay (ELISA) and included: anti-cardiolipin (aCL) IgG/IgM and anti-β2GPI IgG/IgM antibodies (Inova Diagnostics, USA); anti-annexin V IgG/IgM, anti-phosphatidyl serine IgG/IgM and anti-prothrombin IgG/IgM (Orgentec Diagnostica, Germany). Anti-Sm was determined by ELISA (Inova Diagnostics, USA) and anti-dsDNA by indirect immun-fluorescence. Arterial and venous thromboses were also clinically assessed. The statistical analyses were carried out with qui square test, McNemar s test and one-way repeated measures analysis of variance (ANOVA). Results: Pre-vaccination frequency of at least one APL antibody was significantly higher in PAPS patients compared to controls (58% vs. 21%, p=0.003). The overall frequencies of APL antibody at pre-vaccination, 3 weeks and 6 months after immunization remained unchanged in patients (p=0.89) and controls (p=0.83). Further analysis of each evaluated antibody in PAPS revealed that their percentages at pre-vaccination and after 3 weeks and 6 months were also comparable (p>0.05): aCL IgG (42%, 38% and 42%), aCL IgM (22%, 20% and 24%), anti-β2GPI IgG (22%, 22% and 20%), anti-β2GPI IgM (15%, 15% and 18%), anti- annexin V IgG (4.5%, 4.5% and 2.5%), anti-annexin V IgM (uniformly negative), anti-phosphatidyl serine IgG (38%, 35% and 38%), anti- phosphatidyl serine IgM (15%, 13% and 13%), anti-prothrombin IgG (20%, 15% and 18%) and anti-prothrombin IgM (2.5%, 2.5% and 2.5%). The same pattern was observed for the control group (p>0.05). At 3 weeks, 2 PAPS patients developed a new but transient APL anti-body (moderate titer aCL IgG and IgM) whereas at 6 months, new APL antibodies were observed in 6 PAPS patients: 3 moderate titer aCL IgM, 1 moderate anti-β2GPI IgM, 1 low anti-phosphatidyl serine IgG and 1 low anti-prothrombin IgG. Fluctuations of antibody levels were not detected for any evaluated antibody (p>0.05). Of note, anti-Sm and anti-dsDNA autoantibodies were consistently negative during all evaluations. No new arterial or venous thrombosis events occurred during the study period. Conclusion: This was the first study to demonstrate that pandemic non-adjuvant influenza A/H1N1 in PAPS patients does not trigger a change in APL antibody profile or induce lupus specific autoantibodies.- Immunogenicity and safety of the 2009 non-adjuvanted influenza A/H1N1 vaccine in a large cohort of autoimmune rheumatic diseases(2011) SAAD, Carla G. S.; BORBA, Eduardo F.; AIKAWA, Nadia E.; SILVA, Clovis A.; PEREIRA, Rosa M. R.; CALICH, Ana Luisa; MORAES, Julio C. B.; RIBEIRO, Ana C. M.; VIANA, Vilma S. T.; PASOTO, Sandra G.; CARVALHO, Jozelio F.; FRANCA, Ivan L. A.; GUEDES, Lissiane K. N.; SHINJO, Samuel K.; SAMPAIO-BARROS, Percival D.; CALEIRO, Maria T.; GONCALVES, Celio R.; FULLER, Ricardo; LEVY-NETO, Mauricio; TIMENETSKY, Maria do Carmo S.; PRECIOSO, Alexander R.; BONFA, EloisaBackground Despite the WHO recommendation that the 2010-2011 trivalent seasonal flu vaccine must contain A/California/7/2009/H1N1-like virus there is no consistent data regarding its immunogenicity and safety in a large autoimmune rheumatic disease (ARD) population. Methods 1668 ARD patients (systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), ankylosing spondylitis (AS), systemic sclerosis, psoriatic arthritis (PsA), Behcet's disease (BD), mixed connective tissue disease, primary antiphospholipid syndrome (PAPS), dermatomyositis (DM), primary Sjogren's syndrome, Takayasu's arteritis, polymyositis and Granulomatosis with polyangiitis (Wegener's) (GPA)) and 234 healthy controls were vaccinated with a non-adjuvanted influenza A/California/7/2009(H1N1) virus-like strain flu. Subjects were evaluated before vaccination and 21 days post-vaccination. The percentage of seroprotection, seroconversion and the factor increase in geometric mean titre (GMT) were calculated. Results After immunisation, seroprotection rates (68.5% vs 82.9% p < 0.0001), seroconversion rates (63.4% vs 76.9%, p < 0.001) and the factor increase in GMT (8.9 vs 13.2 p < 0.0001) were significantly lower in ARD than controls. Analysis of specific diseases revealed that seroprotection significantly reduced in SLE (p < 0.0001), RA (p < 0.0001), PsA (p=0.0006), AS (p=0.04), BD (p=0.04) and DM (p=0.04) patients than controls. The seroconversion rates in SLE (p < 0.0001), RA (p < 0.0001) and PsA (p=0.0006) patients and the increase in GMTs in SLE (p < 0.0001), RA (p < 0.0001) and PsA (p < 0.0001) patients were also reduced compared with controls. Moderate and severe side effects were not reported. Conclusions The novel recognition of a diverse vaccine immunogenicity profile in distinct ARDs supports the notion that a booster dose may be recommended for diseases with suboptimal immune responses. This large study also settles the issue of vaccine safety. (ClinicalTrials.gov #NCT01151644)

T.; CANCADO, Eduardo; TUSTUMI, Francisco; TERRABUIO, Debora R. B.; LEON, Elaine P.; SILVA, Clovis A.; BORBA, Eduardo F.; BONFA, EloisaBackground Autoantibodies to ribosomal P proteins (anti-rib P) are specific serological markers for systemic lupus erythematosus (SLE) and are associated with liver involvement in this disease. The similarity in autoimmune background between autoimmune hepatitis (AIH) and SLE-associated hepatitis raises the possibility that anti-rib P antibodies might also have relevance in AIH. Aims To evaluate the frequency and clinical significance of anti-rib P antibodies in a large AIH cohort. Methods Sera obtained at diagnosis of 96 AIH patients and of 82 healthy controls were tested for IgG anti-ribosomal P protein by ELISA. All of the sera were also screened for other lupus-specific autoantibodies, three patients with the presence of anti-dsDNA (n=1) and anti-Sm (n=2) were excluded. Results Moderate to high titres (>40U) of anti-rib P antibody were found in 9.7% (9/93) of the AIH patients and none of the controls (P=0.003). At presentation, AIH patients with and without anti-rib P antibodies had similar demographic/clinical features, including the frequency of cirrhosis (44.4 vs. 28.5%, P=0.44), hepatic laboratorial findings (0.05). Importantly, at the final observation (follow-up period 10.2 +/- 4.9years), the AIH patients with anti-rib P had a significantly higher frequency of cirrhosis compared with the negative group (100 vs. 60%, P=0.04). Conclusion The novel demonstration of anti-rib P in AIH patients without clinical or laboratory evidence of SLE suggests a common underlying mechanism targeting the liver in these two diseases. In addition, this antibody appears to predict the patients with worse AIH prognoses.
