Correspondence (letter to the editor): Common Constellation

In their article, the authors write that administering leukotriene receptor antagonists should be considered in adult patients with asthma if concomitant allergic rhinitis is present.

Since this constellation can be assumed to be common, which further criteria justify the use of leukotriene antagonists or speak against their use? For example, in treatment step 3, is a combination of low-dose inhaled corticosteroids and leukotriene antagonists beneficial if severe seasonal rhinitis is present that is already being treated with cortisone inhalers (for example, 2×1 puffs of mometasone furoate)?
