ReviewEnzyme replacement therapy with galsulfase for mucopolysaccharidosis type VI.
Mucopolysaccharidosis type VI or Maroteaux-Lamy syndrome is a rare genetic disorder caused by the deficiency of arylsulphatase B. The resultant accumulation of dermatan sulphate causes lysosomal damage.The clinical symptoms are related to skeletal dysplasia (i.e. short stature and degenerative joint disease). Other manifestations include cardiac disease, impaired pulmonary function, ophthalmological complications, hepatosplenomegaly, sinusitis, otitis, hearing loss and sleep apnea. Intellectual impairment is generally absent. Clinical manifestation is typically by two or three years of age; however, slowly progressive cases may not present until adulthood.Enzyme replacement therapy with galsulfase is considered a new approach for treating mucopolysaccharidosis type VI. ⋯ The results of one small study (based on 24-week randomised phase of the study and prior to the open-label extension) demonstrated that galsulfase is more effective than placebo in people with MPS VI, with significant improvements in the 12-minute walk test and a reduction in urinary glycosaminoglycans.There were no significant changes in cardiac or pulmonary functions, liver or spleen volume, overnight apnea-hypopnea, height and weight, quality of life and adverse effects.Further studies are needed to obtain more information on the long-term effectiveness and safety of enzyme replacement therapy with galsulfase.

Review Meta AnalysisVaccines for preventing herpes zoster in older adults.
Herpes zoster, also known as 'shingles', is a neurocutaneous disease characterised by the reactivation of the latent varicella zoster virus (VZV), the virus that causes chickenpox when immunity to VZV declines. It is an extremely painful condition that can last many weeks or months and it can significantly compromise the quality of life of affected individuals. The natural process of aging is associated with a reduction in cellular immunity and this predisposes older people to herpes zoster. Vaccination with an attenuated form of VZV activates specific T cell production avoiding viral reactivation. The Food and Drug Administration has approved a herpes zoster vaccine with an attenuated active virus for clinical use among older adults, which has been tested in large populations. A new adjuvanted recombinant VZV subunit zoster vaccine has also been tested. It consists of recombinant VZV glycoprotein E and a liposome-based AS01B adjuvant system. This new vaccine is not yet available for clinical use. ⋯ Herpes zoster vaccine is effective in preventing herpes zoster disease and this protection can last three years. In general, zoster vaccine is well tolerated; it produces few systemic adverse events and injection site adverse events of mild to moderate intensity.There are studies of a new vaccine (with a VZV glycoproteic fraction plus adjuvant), which is currently not yet available for clinical use.

Review Meta AnalysisBlood pressure lowering efficacy of coenzyme Q10 for primary hypertension.
Blood pressure is a commonly measured risk factor for non-fatal and fatal cardiovascular adverse events such as heart attacks and strokes. Clinical trials have suggested that coenzyme Q10, a non-prescription nutritional supplement, can effectively lower blood pressure (BP). When this review was completed and published in October 2009, it concluded that "due to the possible unreliability of the 3 included studies, it is uncertain whether or not coenzyme Q10 reduces blood pressure in the long-term management of primary hypertension." ⋯ This review provides moderate-quality evidence that coenzyme Q10 does not have a clinically significant effect on blood pressure. In one of three trials reporting adverse effects, coenzyme Q10 was well tolerated. Due to the small number of individuals and studies available for analysis, more well-conducted trials are needed.
