Meningococcal B Vaccine Immunogenicity in Children With Defects in Complement and Splenic Function.

Background: The capsular group B meningococcal vaccine (4CMenB) is recommended for children with complement deficiencies, asplenia, and splenic dysfunction; however, data on the immunogenicity of 4CMenB in these "at-risk" children are missing.

Methods: Participants aged 2 to 17 years in Italy, Spain, Poland, the United Kingdom, and Russia with complement deficiencies, asplenia, or splenic dysfunction received 2 doses of 4CMenB 2 months apart, as did healthy children in the control group. Exogenous and endogenous human complement serum bactericidal activity (SBA) was determined at baseline and 1 month after the second immunization against 4 test strains: H44/76 (assessing vaccine antigen factor H binding protein), 5/99 (Neisserial adhesion A), NZ98/254 (Porin A), and M10713 (Neisserial heparin binding antigen).

Reduced schedules of 4CMenB vaccine in infants and catch-up series in children: Immunogenicity and safety results from a randomised open-label phase 3b trial.

Background: This study evaluated the immunogenicity and safety of a licensed meningococcal serogroup B vaccine (4CMenB) administered alone according to reduced schedules in infants or catch-up series in children.

Methods: In this open-label, multicentre, phase 3b study (NCT01339923), infants randomised 1:1:1 received 4CMenB: 2+1 doses at 3½-5-11months or 6-8-11months of age, 3+1 doses at ages 2½-3½-5-11months. Children aged 2-10years received 2 catch-up doses administered 2months apart.

Immunogenicity and safety of concomitant administration of meningococcal serogroup B (4CMenB) and serogroup C (MenC-CRM) vaccines in infants: A phase 3b, randomized controlled trial.

Background: After implementation of routine infant MenC vaccination, MenB remains a serious cause of meningococcal disease, yet to be targeted by vaccination programs in several countries. This study (NCT01339923) investigated the immunogenicity and safety of MenC CRM-conjugated vaccine (MenC-CRM) concomitantly administered with MenB vaccine (4CMenB).

Methods: Infants (N=251) were randomised 1:1 to receive 4CMenB and MenC-CRM (Group 1) or MenC-CRM alone (Group 2) at 3 and 5months (M3, M5) and a booster at 12months of age (M12), and pneumococcal vaccine at M3, M5, M7, M12.

A double-blind randomised study to evaluate the efficacy and safety of bindarit in preventing coronary stent restenosis.

Aims: Bindarit (BND) is a selective inhibitor of monocyte chemotactic protein-1 (MCP-1/CCL2), which plays an important role in generating intimal hyperplasia. Our aim was to explore the efficacy and safety of bindarit in preventing restenosis following percutaneous coronary intervention.

Methods And Results: A phase II, double-blind, multicentre randomised trial included 148 patients randomised into three arms (BND 600 mg, n=48; BND 1,200 mg, n=49; PLB, n=51).

Supra-molecular association and polymorphic behaviour in systems containing bile acid salts.

A wide number of supra-molecular association modes are observed in mixtures containing water and bile salts, BS, (with, eventually, other components). Molecular or micellar solutions transform into hydrated solids, fibres, lyotropic liquid crystals and/or gels by raising the concentration, the temperature, adding electrolytes, surfactants, lipids and proteins. Amorphous or ordered phases may be formed accordingly.

Atypical primary headache responding to finger pressure: possible involvement of the vagus nerve?

We describe a case of atypical primary headache strongly responsive to prolonged pressure in the anterior aspect of the neck. We hypothesize that, at least in this case, the trigemino-cervical system and its connections with the vagus nerve are involved.

Ischaemic penumbra: highlights.

The ischaemic penumbra was described for the first time in the late 1970s as a ring of hypoperfused zone surrounding the region of complete infarction. The penumbral zone is a functionally silent tissue which is able to regain its function if promptly reperfused. This implies that the ischaemic penumbra is not a static but a "dynamic" and "time-dependent" concept.
