Possible Influence of the Route of Treatment Administration on Treatment Adherence in Patients With Multiple Sclerosis.

PURPOSE: Multiple sclerosis is a chronic, demyelinating, and degenerative disease of the central nervous system with an immune-based pathologic origin. The present pilot study aimed to assess whether the change in the route of treatment administration is associated with a variation in adherence and whether there is a change in quality of life, treatment satisfaction, and fatigue. METHODS: Patients with relapsing-remitting multiple sclerosis who were >18 years of age and who used to receive immunomodulatory parenteral treatment and were ready to change administration route were eligible for the study. Data were collected at baseline and 3 months later. Adherence, quality of life, treatment satisfaction, and fatigue were measured via the following questionnaires: Morisky-Green questionnaire on patient-reported medication adherence, Multiple Sclerosis Quality of Life Instrument, Treatment Satisfaction Questionnaire for Medication, and Modified Fatigue Impact Scale. FINDINGS: The study sample included 30 patients (mean age, 43.2 years; age range, 24-71 years; 60% female and 40% male). There was a significant improvement in adherence (p = 0.048). Mean (SD) physical and mental health quality-of-life summary scores varied from 52.50 (24.15) and 54.13 (21.24) to 67.55 (20.92) and 62.30 (21.75) (p < 0.001 and p = 0.001, d = -0.426 and d = -0.643, respectively). In the Treatment Satisfaction Questionnaire for Medication, an improvement of the score was observed in effectiveness of the medication (p = 0.0041, d = -0.563), adverse effects of the medication (p < 0.001, d = -0.976), convenience of the medication (p < 0.001, d = -1.235), and global satisfaction (p = 0.006, d = -0.725). Patients had a higher mean (SD) score (45.13 [26.7]) on the Modified Fatigue Impact Scale while receiving injectable treatment compared with that obtained with oral treatment (34.86 [23.16]; p = 0.009, d = 0.41). IMPLICATIONS: When the route of administration changed from injectable to oral, there was an increase in adherence, quality of life, and degree of patient satisfaction with their treatment and a decrease in the degree of fatigue.

Biochemical and nutritional markers and antioxidant activity in metabolic syndrome.

BACKGROUND AND OBJECTIVES: 1) Nutritional assessment of the diet followed by patients with metabolic syndrome, and 2) biochemical analysis of the oxidation-reduction level in patients with metabolic syndrome. MATERIAL AND METHODS: A cross-sectional study was conducted in patients with metabolic syndrome in Murcia. Fifty-three patients, 33 with and 20 without (control group) metabolic syndrome, were selected. The intervention consisted of completion of a recall survey and a test to nutritionally assess dietary intake. Anthropometric and laboratory variables, including those related to antioxidant activity, were also tested. RESULTS: Antioxidant activity was within normal limits in both groups (1.7 ± 0.2 mmol/L in the control group and 1.8 ± 0.1 mmol/L in the metabolic syndrome group) (NS). Superoxide dismutase levels were not significantly different between the groups. Mean glutathione reductase levels (U/L) were higher in the control group as compared to patients with metabolic syndrome (P<.05). As regards oxidative stress biomarkers, mean isoprostane levels were higher in the control group (4.9 ± 6.2 ng/mL) than in metabolic syndrome patients (3.5 ± 3.9 ng/mL) (P<.05). Oxidized LDL values tended to be higher in metabolic syndrome patients (96 ± 23.2U/L) as compared to the control group (86.2 ± 17.3 U/L), but differences were not significant. CONCLUSIONS: There is a trend to a poorer nutritional and biochemical profile in patients with metabolic syndrome, who also tend to have a greater degree of oxidative stress.
