Right middle lobe atelectasis in children with asthma and prognostic factors. Allergology international : official journal of the Japanese Society of Allergology, 65(3), 253–258.1323-89301440-1592https://doi.org/10.1016/j.alit.2015.12.002https://hdl.handle.net/20.500.12587/6530Background: Although right middle lobe (RML)-atelectasis of the lungs is a common complication of asthma, the relevant data is limited. The aim of this study is to define the characteristics of RML atelectasis in asthma during childhood. Methods: Children with asthma who had recently developed RML atelectasis were included; anti-inflammatory medications, clarithromycin, and inhaled salbutamol were prescribed, chest-physiotherapy (starting on the sixth day) was applied. Patients were reevaluated on the sixth, fourteenth, thirtieth, and ninetieth days, chest X-rays were taken if the atelectasis had not resolved at the time of the previous visit. Results: Twenty-seven patients (6.8 (4.8-8.3) years, 48.1% male) with RML atelectasis were included. Symptoms started 15 (7-30) days before admission. The thickness of the atelectasis was 11.8 +/- 5.8 mm; FEV1% was 75.9 +/- 14.2 and Childhood Asthma Control Test scores were 11.8 +/- 5.6 at the time of admission. The atelectasis had been resolved by the sixth (n = 3), fourteenth (n = 9), thirtieth (n = 10), and ninetieth days (n = 3). The treatment response of the patients whose atelectasis resolved in fourteen days was better on the sixth-day (atelectasis thickness: 4.7 +/- 1.7 vs. 11.9 +/- 7.3 mm, p = 0.021) compared to those whose atelectasis resolved later. Nearly half (54.5%) of the patients whose atelectasis had resolved by fourteen days were using controller medications at the time of admission. However, only two patients (13.3%) were on controller treatment in the latter group (p = 0.032). Regression analysis didn't reveal any prognostic factors for the early resolution of atelectasis. Conclusions: Early diagnosis and treatment of RML atelectasis prevents complications. Patients who had early resolution of atelectasis had already been on anti-inflammatory medications, and responded better to aggressive treatment within the first week.
