Background Apart from compression therapy, physical therapy has scarcely been evaluated in the treatment of chronic venous disorders (CVDs). Spa treatment is a popular way to administer physical ...therapy for CVDs in France, but its efficacy has not yet been assessed in a large trial. The objective was to assess the efficacy of spa therapy for patients with advanced CVD (CEAP clinical classes C4-C5). Methods This was a single-blind (treatment concealed to the investigators) randomized, multicenter, controlled trial (French spa resorts). Inclusion criteria were primary or post-thrombotic CVD with skin changes but no active ulcer (C4a, C4b, or C5). The treated group had the usual 3-week spa treatment course soon after randomization; the control group had spa treatment after the 1-year comparison period. All patients continued their usual medical care including wearing compression stockings. Treatment consisted of four balneotherapy sessions per day for 6 days a week. Follow-up was performed at 6, 12 and 18 months by independent blinded investigators. The main outcome criterion was the incidence of leg ulcers at 12 months. Secondary criteria were a modified version of the Venous Clinical Severity Score, a visual analog scale for leg symptoms, and the Chronic Venous Insufficiency Questionnaire 2 and EuroQol 5D quality-of-life autoquestionnaires. Results Four hundred twenty-five subjects were enrolled: 214 in the treatment group (Spa) and 211 in the control group (Ctr); they were similar at baseline regarding their demographic characteristics, the severity of the CVD, and the outcome variables. At 1 year, the incidence of leg ulcers was not statistically different (Spa: +9.3%; 95% confidence interval CI, +5.6 - +14.3; Ctr: +6.1%; 95% CI, +3.2 - +10.4), whereas the Venous Clinical Severity Score improved significantly in the treatment group (Spa: −1.2; 95% CI, −1.6 - −0.8; Ctr: −0.6; 95% CI, −1.0 - −0.2; P = .04). A significant difference favoring spa treatment was found regarding symptoms after 1 year (Spa: −0.03; 95% CI, −0.57 - +0.51; Ctr: +0.87; 95% CI,+0.46 - +1.26; P = .009). EuroQol 5D improved in the treatment group (Spa: +0.01; 95% CI, −0.02 - +0.04) while it worsened (Ctr: −0.07; 95% CI, −0.10 - −0.04) in the control group ( P < .001). A similar pattern was found for the Chronic Venous Insufficiency Questionnaire 2 scale (Spa: −2.0; 95% CI, −4.4 - +0.4; Ctr: +2.4; 95% CI, +0.2 - +4.7; P = .008). The control patients showed similar improvements in clinical severity, symptoms, and quality of life after their own spa treatment (day 547). Conclusions In this study, the incidence of leg ulcers was not reduced after a 3-week spa therapy course. Nevertheless, our study demonstrates that spa therapy provides a significant and substantial improvement in clinical status, symptoms, and quality of life of patients with advanced venous insufficiency for at least 1 year.

Vascular lesions are frequent in Behçet's disease, and among them, deep venous thrombosis may occur in up to one-third of patients. Treatment is based on immunosuppressive drugs in addition to ...anticoagulants. We report the case of a young woman who presented with an acute iliofemoral venous thrombosis. Acute treatment with endovascular thrombectomy and catheter-directed fibrinolysis failed, probably because of the inflammatory status of the vessel wall. Recanalization with stenting of the obstructed common femoral and iliac veins 1 year later was successful under immunosuppressive therapy. This case suggests that endovascular treatment of venous thrombosis in Behçet's disease may be conducted successfully in nonactive venous lesions under immunosuppressive therapy.

Summary Background The ongoing Ebola outbreak led to accelerated efforts to test vaccine candidates. On the basis of a request by WHO, we aimed to assess the safety and immunogenicity of the ...monovalent, recombinant, chimpanzee adenovirus type-3 vector-based Ebola Zaire vaccine (ChAd3-EBO-Z). Methods We did this randomised, double-blind, placebo-controlled, dose-finding, phase 1/2a trial at the Centre Hospitalier Universitaire Vaudois, Lausanne, Switzerland. Participants (aged 18–65 years) were randomly assigned (2:2:1), via two computer-generated randomisation lists for individuals potentially deployed in endemic areas and those not deployed, to receive a single intramuscular dose of high-dose vaccine (5 × 1010 viral particles), low-dose vaccine (2·5 × 1010 viral particles), or placebo. Deployed participants were allocated to only the vaccine groups. Group allocation was concealed from non-deployed participants, investigators, and outcome assessors. The safety evaluation was not masked for potentially deployed participants, who were therefore not included in the safety analysis for comparison between the vaccine doses and placebo, but were pooled with the non-deployed group to compare immunogenicity. The main objectives were safety and immunogenicity of ChAd3-EBO-Z. We did analysis by intention to treat. This trial is registered with ClinicalTrials.gov , number NCT02289027. Findings Between Oct 24, 2014, and June 22, 2015, we randomly assigned 120 participants, of whom 18 (15%) were potentially deployed and 102 (85%) were non-deployed, to receive high-dose vaccine (n=49), low-dose vaccine (n=51), or placebo (n=20). Participants were followed up for 6 months. No vaccine-related serious adverse events were reported. We recorded local adverse events in 30 (75%) of 40 participants in the high-dose group, 33 (79%) of 42 participants in the low-dose group, and five (25%) of 20 participants in the placebo group. Fatigue or malaise was the most common systemic adverse event, reported in 25 (62%) participants in the high-dose group, 25 (60%) participants in the low-dose group, and five (25%) participants in the placebo group, followed by headache, reported in 23 (57%), 25 (60%), and three (15%) participants, respectively. Fever occurred 24 h after injection in 12 (30%) participants in the high-dose group and 11 (26%) participants in the low-dose group versus one (5%) participant in the placebo group. Geometric mean concentrations of IgG antibodies against Ebola glycoprotein peaked on day 28 at 51 μg/mL (95% CI 41·1–63·3) in the high-dose group, 44·9 μg/mL (25·8–56·3) in the low-dose group, and 5·2 μg/mL (3·5–7·6) in the placebo group, with respective response rates of 96% (95% CI 85·7–99·5), 96% (86·5–99·5), and 5% (0·1–24·9). Geometric mean concentrations decreased by day 180 to 25·5 μg/mL (95% CI 20·6–31·5) in the high-dose group, 22·1 μg/mL (19·3–28·6) in the low-dose group, and 3·2 μg/mL (2·4–4·9) in the placebo group. 28 (57%) participants given high-dose vaccine and 31 (61%) participants given low-dose vaccine developed glycoprotein-specific CD4 cell responses, and 33 (67%) and 35 (69%), respectively, developed CD8 responses. Interpretation ChAd3-EBO-Z was safe and well tolerated, although mild to moderate systemic adverse events were common. A single dose was immunogenic in almost all vaccine recipients. Antibody responses were still significantly present at 6 months. There was no significant difference between doses for safety and immunogenicity outcomes. This acceptable safety profile provides a reliable basis to proceed with phase 2 and phase 3 efficacy trials in Africa.
