Intranasal beclomethasone dipropionate in the treatment of common cold. The common cold: effects of intranasal fluticasone propionate treatment.
Sinusitis is usually considered a complication of viral rhinitis. Virus infections in the upper respiratory tract lead to mucosal swelling, which may obstruct paranasal sinus outflow, resulting in infection in the paranasal sinuses. Topical nasal steroids have been found beneficial in a variety of acute and chronic nasal conditions including allergic and nonallergic rhinitis and chronic rhinosinusitis. The purpose of this study was to examine whether the intranasal inhalation powder beclomethasone dipropionate (BDP) 400 micrograms/day treatment has a beneficial or harmful effect on symptoms and signs of common cold, and whether or not it can prevent common cold complications. A total of 54 patients were randomized, 26 into the placebo-group and 28 into the BDP group. During the 14-day follow-up, there were on an average 10.3 symptomatic days in the placebo group and 10.7 days in the BDP group (p = 0.72). The use of intranasal BDP in the treatment of common cold neither reduced symptoms caused by inflammation nor did it shorten the recovery time. On the other hand, because BDP does not increase the risk of complications or significantly prolong the recovery during the common cold, there is no need to discontinue its use in the patients with allergic rhinitis or nasal polyposis. A double-blind, randomized, placebo-controlled trial was conducted to study the effect of the intranasal corticosteroid, fluticasone propionate (FP), in the naturally occurring common cold.
                One hundred ninety-nine young adults received high-dose FP (200 microg four times daily) or placebo beginning 24 to 48 hours after onset of the common cold for 6 days. All symptoms were recorded on diary cards on days 1 to 20, and clinical examinations were carried out on days 1, 7, and 21. Nasopharyngeal aspirates were collected on days 1 and 7 for detection of rhinoviruses (found in 105 subjects) and Streptococcus pneumoniae, Haemophilus influenzae, or Moraxella catarrhalis (found in 52 subjects) in the nasopharynx.
                In general, FP treatment had no clinically recognizable effects on the symptoms of the common cold, although it significantly reduced nasal congestion and cough on some study days. After treatment, rhinoviruses were cultured more often in the FP treatment group (37% vs 14%, p < 0.001), but this had no effect on the symptoms of common cold. FP treatment produced no changes in the colonization of pathogenic bacteria in the nasopharynx. Some symptoms of common cold were significantly more severe during days 1 to 10 (p < 0.05) in subjects found to have positive cultures for S. pneumoniae, H. influenzae, or M. catarrhalis in the nasopharynx on day 1 (n = 33).
                FP treatment does not have any marked effects on the symptoms of the common cold. FP treatment induced prolonged shedding of viable rhinoviruses. Some symptoms of the common cold were significantly more severe in subjects with pathogenic bacteria in the nasopharynx.
Current evidence does not support the use of intranasal corticosteroids for symptomatic relief from the common cold. However, there were only two trials and limited statistical power. Further large randomised placebo-controlled trials in adults and children are required to answer this question.
