Bronchiectasis is characterised by chronic sputum production,bronchial wall dilation,recurrent infection and airflow limitation. Methylxanthines are used in the management of airflow limitation associated with asthma and COPD, where they are also purported to have anti-inflammatory properties. In theory they may be of use in bronchiectasis. ⋯ Further research is required to establish if the methylxanthines have a role in the treatment of bronchiectasis.

ReviewBisphosphonates for osteoporosis in people with cystic fibrosis.
Osteoporosis is a disorder of bone mineralization that can lead to reduced bone mineral density and an increased risk for fractures. It is found in about one third of adults with cystic fibrosis. Bisphosphonates have been shown to increase bone mineral density and decrease the risk of new fractures in post-menopausal women and in patients receiving long-term oral corticosteroids. ⋯ Intravenous pamidronate increases bone mineral density at axial sites in people with cystic fibrosis, although it can cause severe bone pain in patients not receiving corticosteroids. Additional studies in larger populations are needed to determine the effect on fracture rate and survival.

Alcohol is a major cause of liver disease in the Western world today. S-adenosyl-L-methionine (SAMe) acts as a methyl donor for all known biological methylation reactions and participates in the synthesis of glutathione, the main cellular anti-oxidant. Randomised clinical trials have addressed the question whether SAMe has any efficacy in patients with alcoholic liver diseases. ⋯ This systematic review could not demonstrate any significant effect of SAMe on mortality, liver related mortality, mortality or liver transplantation, and liver complications of patients with alcoholic liver disease. SAMe should not be used for alcoholic liver disease outside randomised clinical trials.

Anticholinergic agents block bronchoconstriction mediated by the vagus nerve and may also dry up bronchial secretions. They are effective in obstructive airways disease and may be beneficial in bronchiectasis ⋯ No formal recommendations can be made about the use of anticholinergic therapy in acute or stable bronchiectasis based on the literature currently available.

ReviewBeclomethasone at different doses for chronic asthma (review).
Beclomethasone dipropionate (BDP) is available in a wide range of daily doses for the treatment of long-term asthma. ⋯ BDP appears to demonstrate a shallow dose response effect in long-term asthma for a small number of efficacy outcomes over range of daily doses from 400 mcg/d to 1600 mcg/d, although the clinical significance of the improvements afforded by higher doses is questionable.
