EditorialEditorial update on emerging drugs for cancer cachexia.
Cancer cachexia is a multifactorial syndrome characterized by progressive skeletal muscle wasting and weakness. It affects most patients with advanced cancers, reduces quality of life and accounts for more than 20% of all cancer-related deaths. ⋯ However, the multifactorial pathogenesis indicates strongly that the most effective treatments will come from drug combination approaches. Drug treatments should ideally be combined with exercise training to maximize efficacy and ultimately reduce mortality and enhance the quality of life of patients with cancer cachexia.

The tuberculosis epidemic continues in much of the developing world fueled by the concurrent HIV epidemic. Due to the emergence of multidrug and extensively drug-resistant isolates of tuberculosis, there is a critical need for new drug regimens for the treatment of this disease. Currently, five new compound classes are in various stages of clinical development for tuberculosis. ⋯ The challenge in antituberculosis drug development is to make available to patients highly effective regimens which present substantial barriers to resistance development in an affordable formulation. Shortening the length of therapy from the current 6 to 3 months or less is a goal for the newly developed regimens. For the first time in many years, there are bright prospects for improving regimens for the therapy of tuberculosis.

Cystic fibrosis (CF), one of the major respiratory diseases, is caused by mutations in a gene encoding for a chloride channel. Abnormal transepithelial ion transport leads to a reduced volume of the airway surface liquid layer and reduced mucociliary clearance. ⋯ CF drug therapy is moving rapidly from symptomatic therapy to treatment of the underlying pathophysiology.

Fibromyalgia syndrome (FMS) is currently perceived by rheumatologists and pain physicians alike as representing the classic condition of central sensitization. This term has come to denote a condition in which chronic, widespread pain is attributed mainly to an increase in the processing and handling of pain by the CNS. Thus, effective treatment of the pain of FMS must be directed at the function of the CNS. Over recent years, the pharmacological industry has focused increasing attention on this syndrome, leading to the recent approval of three first medications specifically indicated in the treatment of FMS (i.e., pregabalin, duloxetine and milnacipran). Nonetheless, treatment of FMS remains challenging and in many cases incompletely successful. Issues with drug compliance and side effects, as well as limitations of intrinsic effectiveness, hamper the outcome in many cases. Thus, FMS continues to pose a significantly unmet medical need. ⋯ Following the introduction of three medications specifically indicated in the management of FMS over the last 4 years, additional research is actively leading towards the introduction of new drugs aimed at improving symptoms related to pain and sleep in FMS. Physicians involved in the treatment of FMS patients are required to keep up-to-date on these promising avenues of progress and to be ready to incorporate them into clinical use.

Atopic eczema (AE) is a chronic relapsing inflammatory skin condition and one of the most common, potentially debilitating diseases with increasing incidence. ⋯ Existing treatment modalities such as barrier repair therapy, topical immunosuppressive agents, antiseptic treatment as well as systemic treatment options are discussed. The review aims to summarize the most recent findings of more innovative treatment approaches such as modulation of cytokines or chemokines, modulation of T-cell responses or anti-IgE therapy.
