Relación entre la estación del año y la gravedad de los síntomas en pacientes con fibromialgia / Relationship between season of the year and severity of symptoms in patients with fibromyalgia

Antecedentes y objetivo: Es frecuente que los pacientes con fibromialgia refieran que ciertas estaciones del año agravan sus síntomas. Como objetivo primario se determinó la asociación entre síntomas claves de la fibromialgia y estación del año. Como objetivo secundario se determinó la existencia de diferencias en función de los niveles de ansiedad o depresión.Material y métodoMuestra de conveniencia formada por 471 participantes con fibromialgia evaluados antes de iniciar un tratamiento multidisciplinar. Se recogieron datos demográficos y meteorológicos y se evaluaron, mediante instrumentos estandarizados, la intensidad del dolor, la funcionalidad, la fatiga, la rigidez, la calidad del sueño, así como la ansiedad y la depresión.ResultadosLos diferentes grupos estacionales fueron homogéneos en edad, género, nivel educativo, estado marital y situación laboral. No se encontraron diferencias significativas en intensidad del dolor (F=1,334; p=0,265), funcionalidad (F=0,402; p=0,669), fatiga (F=0,714; p=0,490), rigidez (F=0,299; p=0,741), ansiedad (F=0,376; p=0,687), depresión (F=0,608; p=0,545), distrés psicológico (F=0,261; p=0,770), duración del sueño (F=1,507; p=0,223) o el índice de problemas de sueño (F=0,343; p=0,710).ConclusionesNo se han encontrado diferencias en la intensidad de los síntomas de la fibromialgia ni en los porcentajes de gravedad entre las distintas estaciones del año. La ansiedad ha sido más prevalente que la depresión, posiblemente debido a las propias características de la muestra, con mayoría de pacientes con perfil disfuncional. (AU)

Background and objective: Fibromyalgia patients often report that certain seasons aggravate their symptoms. The main objective was to determinate the association between key symptoms of fibromyalgia and the season of the year. A secondary objective was to determinate the existence of differences based on levels of anxiety or depression.Material and methodConvenience sample made up of 471 participants with fibromyalgia evaluated before starting multidisciplinary treatment. Demographic and meteorological data were collected. Clinical data were assessed with standardized instruments of pain intensity, functionality, fatigue, stiffness, sleep quality, anxiety and depression.ResultsThe different groups of participants were homogeneous for age, gender, educational level, marital status and employment situation. No significant differences were found in pain intensity (F=1.334; P=.265), functionality (F=.402; P=.669), fatigue (F=.714; P=.490), stiffness (F=.299; P=.741), anxiety (F=.376; P=.687), depression (F=.608; P=.545), psychological distress (F=.261; P=.770), sleep quantity (F=1.507; P=.223) or sleep disturbances (F=.343; P=.710).ConclusionsNo differences were found in the intensity of fibromyalgia symptoms, nor in the percentages of severity among the different seasons of the year. Anxiety was more prevalent than depression, possibly due to the characteristics of the sample itself, with the majority of patients with a dysfunctional profile. (AU)

Significant in vivo anti-inflammatory activity of Pytren4Q-Mn a superoxide dismutase 2 (SOD2) mimetic scorpiand-like Mn (II) complex.

BACKGROUND: The clinical use of purified SOD enzymes has strong limitations due to their large molecular size, high production cost and immunogenicity. These limitations could be compensated by using instead synthetic SOD mimetic compounds of low molecular weight. BACKGROUND/METHODOLOGY: We have recently reported that two SOD mimetic compounds, the Mn(II) complexes of the polyamines Pytren2Q and Pytren4Q, displayed high antioxidant activity in bacteria and yeast. Since frequently molecules with antioxidant properties or free-radical scavengers also have anti-inflammatory properties we have assessed the anti-inflammatory potential of Pytren2Q and Pytren4Q Mn(II) complexes, in cultured macrophages and in a murine model of inflammation, by measuring the degree of protection they could provide against the cellular injury produced by lipopolisacharide, a bacterial endotoxin. PRINCIPAL FINDINGS: In this report we show that the Mn(II) complex of Pytren4Q but not that of Pytren2Q effectively protected human cultured THP-1 macrophages and whole mice from the inflammatory effects produced by LPS. These results obtained with two molecules that are isomers highlight the importance of gathering experimental data from animal models of disease in assessing the potential of candidate molecules. CONCLUSION/SIGNIFICANCE: The effective anti-inflammatory activity of the Mn(II) complex of Pytren4Q in addition to its low toxicity, water solubility and ease of production would suggest it is worth taking into consideration for future pharmacological studies.

Body mass index and response to a multidisciplinary treatment of fibromyalgia.

The purpose of this study is to determine whether there are some differences in the treatment responses to a multidisciplinary fibromyalgia (FM) treatment related with the baseline body mass index (BMI) of the participants. Inclusion criteria consisted of female sex, a diagnosis of FM (American College of Rheumatology criteria), age between 18 and 60 years, and between 3 and 8 years of schooling. Baseline BMI was determined, and patients were randomly assigned to one of the two treatment conditions: conventional pharmacologic treatment or multidisciplinary treatment. Outcome measures were pain intensity, functionality, catastrophizing, psychological distress, health-related quality of life, and sleep disturbances. One hundred thirty patients participated in the study. No statistical significant differences regarding pre-treatment outcomes were found among the different BMI subgroups, and between the two experimental conditions for each BMI category. General linear model analysis showed a significant interaction group treatment × time in pain intensity (p < .01), functionality (p < .0001), catastrophizing (p < .01), psychological distress (p < .0001), sleep index problems (p < .0001), and health-related quality of life (p < .05). No significant interactions were found in BMI × time, and in BMI × group treatment × time. There are not differences among normal weight, overweight and obese patients with FM regarding their response to a multidisciplinary treatment programme for FM which combines pharmacological treatment, education, physical therapy and cognitive behavioural therapy.

Efficacy of a multidisciplinary fibromyalgia treatment adapted for women with low educational levels: a randomized controlled trial.

OBJECTIVE: Multidisciplinary treatments of fibromyalgia (FM) have demonstrated efficacy. Nevertheless, they have been criticized for not maintaining their benefits and for not being studied for specific populations. Our objectives were to determine the efficacy of a multidisciplinary treatment for FM adapted for patients with low educational levels and to determine the maintenance of its therapeutic benefits during a long-term followup period. METHODS: Inclusion criteria consisted of female sex, a diagnosis of FM (using American College of Rheumatology criteria), age between 18 and 60 years, and between 3 and 8 years of schooling. Patients were randomly assigned to 1 of the 2 treatment conditions: conventional pharmacologic treatment or multidisciplinary treatment. Outcome measures were functionality, sleep disturbances, pain intensity, catastrophizing, and psychological distress. Analysis was by intent-to-treat and missing data were replaced following the baseline observation carried forward method. RESULTS: One hundred fifty-five participants were recruited. No statistically significant differences regarding pretreatment measures were found between the 2 experimental groups. Overall statistics comparison showed a significant difference between the 2 groups in all of the variables studied (P < 0.0001). Mixed linear model analysis demonstrated the superiority of the multidisciplinary treatment in all of the studied variables at posttreatment. The differences were maintained at 12-month followup in sleep disturbances (P < 0.0001), catastrophizing (P < 0.0001), and psychological distress (P < 0.01). CONCLUSION: Multidisciplinary treatment adapted for individuals with low educational levels is effective in reducing key symptoms of FM. Some improvements were maintained 1 year after completing the multidisciplinary treatment.
