American ginseng does not improve fatigue in multiple sclerosis: a single center randomized double-blind placebo-controlled crossover pilot study.

This study examined the safety and efficacy of an escalating dose (100 mg, 200 mg, 400 mg/day) of American ginseng over 6 weeks in a single-center, randomized, double-blind, placebo-controlled, crossover trial with 56 subjects with multiple sclerosis and fatigue. There were no serious adverse events but fatigue on ginseng, as assessed by the Fatigue Severity Scale, was not significantly different from fatigue on placebo.

Memantine for cognitive impairment in multiple sclerosis: a randomized placebo-controlled trial.

BACKGROUND: Memantine, an NMDA antagonist, is effective for moderate to severe Alzheimer's disease. OBJECTIVE: Determine whether memantine improves cognitive performance (CP) among subjects with multiple sclerosis (MS) and cognitive impairment (CI). METHODS: This double-blind, randomized, placebo-controlled trial (Clinicaltrials.gov NCT00300716) compared memantine 10 mg twice a day (4 week titration followed by 12 weeks on the highest tolerated dose) with placebo. The primary outcome was the change from baseline to exit on the Paced Auditory Serial Addition Test (PASAT) and the California Verbal Learning Test-II (CVLT-II) Long Delay Free Recall (LDFR). Secondary outcomes included additional neuropsychological tests; self-report measures of quality of life, fatigue, and depression; and family/caregiver reports of subjects' CI and neuropsychiatric symptoms. RESULTS: The differences between the groups on the change on the PASAT (placebo-memantine = 0.0 correct responses, 95% CI 3.4, 3.4; p = 0.9) and on CVLT-II LDFR (placebo-memantine =-0.6 words, 95% CI -2.1, 0.8; p = 0.4) as well as on the other cognitive tests were not significant. Subjects on memantine had no serious adverse events (AEs) but had more fatigue and neurological AEs as well as, per family members' reports, less cognitive improvement and greater neuropsychiatric symptoms than subjects on placebo. CONCLUSION: Memantine 10 mg twice a day does not improve CP in subjects with MS, ages 18-65, without major depression, who have subjective cognitive complaints and perform worse than one SD below the mean on the PASAT or on the California Verbal Learning Test-II (total recall or delayed free recall).

Clinical trial of a formal group fatigue program in multiple sclerosis.

Fatigue: Take Control is a novel program to teach fatigue management to people with multiple sclerosis (MS) following recommendations in the Fatigue and Multiple Sclerosis guideline. Fatigue: Take Control includes six 2-hour group sessions with DVD viewing, discussion and homework and accompanying participant and leader workbooks. While many people have participated in Fatigue: Take Control programs, its efficacy has not been determined. The objective of this study was to determine whether participation in Fatigue: Take Control reduces fatigue and increases self-efficacy in people with MS. Thirty participants were randomly assigned to a group who immediately participated in the program (FTC) or a wait-list group (WL). The primary outcome was the Modified Fatigue Impact Scale (MFIS) and secondary outcomes were the Multiple Sclerosis Self-Efficacy Scale (MSSE) and the Fatigue Severity Scale (FSS). The MFIS was administered on 10 occasions. Other measures were administered on four occasions. A mixed model tested the effects using all observations. Compared with the WL, the FTC group had significantly more improvement on the MFIS [F(1, 269) = 7.079, p = 0.008] and the MSSE [F(1, 111) = 5.636, p = 0.019]. No significant effect was found for the FSS. Across all visits, fatigue was significantly lower and self-efficacy was significantly higher for the FTC group compared with the WL group. This pilot study demonstrated significant effects in fatigue and self-efficacy among subjects taking the Fatigue: Take Control program, suggesting that this comprehensive program based on the Fatigue and Multiple Sclerosis guideline may be beneficial in MS.

[Maternal death after spontaneous rupture of a uterine artery immediately following delivery: a case report]. / Décès maternel après rupture spontanée d'une artère utérine dans le post-partum immédiat : à propos d'un cas.

We report the case of a maternal death occurring after spontaneous rupture of a uterine artery immediately following delivery. The patient presented abdominal pain and a collapsus one hour after a normal delivery. Laparotomy revealed massive haemoperitoneum and intraperitoneal bleeding from the right uterine artery. Ligature of the uterine artery and hemostasis hysterectomy were performed but the patient died of multivisceral failure 18 h after the delivery. This is the first case report of maternal death occurring after spontaneous rupture of a uterine artery.

Ginkgo biloba for the improvement of cognitive performance in multiple sclerosis: a randomized, placebo-controlled trial.

OBJECTIVES: To determine if Ginkgo biloba (GB) improves the cognitive performance of subjects with multiple sclerosis (MS). METHODS: Randomized, double-blind, placebo-controlled trial of GB, 120 mg twice a day or placebo for 12 weeks. The primary outcomes were: the long delay free recall from the California Verbal Learning Test-II; the Paced Auditory Serial Addition Test; the Controlled Oral Word Association Test; the Symbol Digit Modalities Test; Useful Field of View Test; and the color-word interference condition from the Stroop Color and Word Test. RESULTS: On completion, the GB group (n=20) was 4.5 seconds (95% confidence interval (CI) (7.6, 0.9), P=0.015) faster than the placebo group (n=18) on the color-word interference condition of the Stroop test. Subjects who were more impaired at baseline experienced more improvement with GB (treatment*baseline interaction, F=8.10, P=0.008). We found no differences on the other neuropsychological tests. Subjects on GB reported fewer cognitive difficulties in the Retrospective Memory Scale of the Perceived Deficits Questionnaire than subjects on placebo (1.5 points, 95% CI (2.6, 0.3), P=0.016). No serious drug related side-effects occurred and GB did not alter platelet function assays. CONCLUSION: Overall, GB did not show a statistically significant improvement in cognitive function. A treatment effect trend, limited to the Stroop test, suggests that GB may have an effect on cognitive domains assessed by this test, such as susceptibility to interference and mental flexibility.

A highly immunogenic trivalent T cell receptor peptide vaccine for multiple sclerosis.

BACKGROUND: T cell receptor (TCR) peptide vaccination is a novel approach to treating multiple sclerosis (MS). The low immunogenicity of previous vaccines has hindered the development of TCR peptide vaccination for MS. OBJECTIVE: To compare the immunogenicity of intramuscular injections of TCR BV5S2, BV6S5 and BV13S1 CDR2 peptides in incomplete Freunds adjuvant (IFA) with intradermal injections of the same peptides without IFA. METHODS: MS subjects were randomized to receive TCR peptides/IFA, TCR peptides/saline or IFA alone. Subjects were on study for 24 weeks. RESULTS: The TCR peptides/IFA vaccine induced vigorous T cell responses in 100% of subjects completing the 24-week study (9/9) compared with only 20% (2/10) of those receiving the TCR peptides/saline vaccine (P =0.001). IFA alone induced a weak response in only one of five subjects. Aside from injection site reactions, there were no significant adverse events attributable to the treatment. CONCLUSIONS: The trivalent TCR peptide in IFA vaccine represents a significant improvement in immunogenicity over previous TCR peptide vaccines and warrants investigation of its ability to treat MS.

Lipoic acid in multiple sclerosis: a pilot study.

Lipoic acid (LA) is an antioxidant that suppresses and treats an animal model of multiple sclerosis (MS), experimental autoimmune encephalomyelitis. The purpose of this study was to determine the pharmacokinetics (PK), tolerability and effects on matrix metalloproteinase-9 (MMP-9) and soluble intercellular adhesion molecule-1 (sICAMP-1) of oral LA in patients with MS. Thirty-seven MS subjects were randomly assigned to one of four groups: placebo, LA 600 mg twice a day, LA 1200 mg once a day and LA 1200 mg twice a day. Subjects took study capsules for 14 days. We found that subjects taking 1200 mg LA had substantially higher peak serum LA levels than those taking 600 mg and that peak levels varied considerably among subjects. We also found a significant negative correlation between peak serum LA levels and mean changes in serum MMP-9 levels (T = -0.263, P =0.04). There was a significant dose response relationship between LA and mean change in serum sICAM-1 levels (P =0.03). We conclude that oral LA is generally well tolerated and appears capable of reducing serum MMP-9 and sICAM-1 levels. LA may prove useful in treating MS by inhibiting MMP-9 activity and interfering with T-cell migration into the CNS.

Vesicles and particles of sodium bis(2-ethylhexyl) phosphate in binary and ternary systems.

Vesicles were identified in aqueous solution of pure sodium bis(2-ethylhexyl) phosphate, a short branched chain surfactant. Superficial tension measurements show that the vesicles appear above a molality of 0.02 (0.69 %w). These aggregates are equilibrium structures. The "packing parameter' theory established by Israelachvili et al. allows the prediction of the occurrence of such vesicles. If an organic solvent, such as xylene or ethylhexanoate, is added to the binary system, a different type of aggregate appears, the size of which is determined by several methods including electron microscopy and light scattering. Interfacial tension measurements show that these aggregates would be expected to form above a molality of 0.02. According to our experimental results, the microstructure of these aggregates can be described as micelles and/or vesicles, swollen or not.

Clinical and physiological assessment of asthmatic children treated with beclomethasone dipropionate.

Forty-two perennial asthmatic children were selected for a 12-wk study using beclomethasone dipropionate. The groups included 21 steroid-dependent children (Group I) and 21 patients (Group II) whose disease was of sufficient severity that corticosteroid therapy was contemplated. All children received the drug in a dose of 100 mug 4 times daily. During the study, oral prednisone was withdrawn from the steroid-dependent children while other therapy was essentially unchanged. Group II children underwent a double-blind trial, receiving beclomethasone for 6 wk and placebo for 6 wk. Objective assessment of adrenal and pulmonary function was obtained at regular intervals. For the latter, total lung capacity and its subdivisions, airways resistance, maximum expiratory flow volume, and oxygen tension, were measured in both groups. In Group II static elastic recoil was measured also. For most tests the results were statistically significant. In both groups, 18 of 21 patients demonstrated an excellent clinical response, no evidence of adrenal suppression, and improvement in pulmonary function. Forty of 42 patients were followed for another 12 wk, and 19 of each group did well. After 20-24 wk of therapy, 16% of patients harbored monilia in their oropharynx, and 1 patient had clinical monilial stomatitis. Within the limits of the time of the study, beclomethasone dipropionate appeared to provide adequate clinical control in many chronic, severe, steroid-dependent and nonsteroid-dependent asthmatic children.
