- Background
Acute eosinophilic pneumonia (AEP) is a rare and severe lung condition characterized by a rapid accumulation of eosinophils in the alveoli, leading to respiratory distress. This study analyzed the clinical characteristics of affected patients, aiming to shed light on the relationship between cigarette smoking and AEP.
Methods
This retrospective study analyzed 17 cases of AEP, focusing on patients' smoking habits, clinical symptoms, diagnostic findings, and treatment outcomes. Data were collected from medical records, imaging studies, and bronchoalveolar lavage (BAL) findings.
Results
The study cohort consisted primarily of male military personnel (94.1%), with a mean age of 20.8 years. Symptoms generally appeared approximately 2.82 days prior to hospitalization, with a mean body temperature at admission of 37.6 °C. The mean initial peripheral blood white blood cell count was 15.3×103/μL, with eosinophil percentages starting at 0.2%, peaking at a mean of 16.1%, and reaching as high as 32.4%. BAL fluid analysis showed a mean eosinophil level of 46.6%±15.1% (range, 17%–67%). In most cases, radiological examinations revealed bilateral ground-glass opacities, interlobular septal thickening, various degrees of airspace consolidation, and bilateral pleural effusions. Steroid treatment was administered to 70.5% of patients, lasting a mean of 8.3 days and resulting in significant improvements.
Conclusions
These cases reinforce the strong link between cigarette smoking and AEP. Additionally, these cases demonstrate the importance of obtaining a detailed smoking history and thorough diagnostic assessments, including BAL, in order to facilitate a more rapid diagnosis and early initiation of corticosteroid treatment.

Abstract Objectives Smoking is one of the most important leading causes of lung cancer. Smoking habit is recognized as nicotine dependence, which consists of physical and psychosocial dependence. To evaluate social nicotine dependence, the Kano Test for Social Nicotine Dependence (KTSND) working group developed a new questionnaire. We examined the social nicotine dependence among high school students, university students and patients with lung cancer.
Method We applied Korean version of KTSND(KTSND-K) questionnaire to high school students, university students and patients with lung cancer. Complete data obtained from the 1333 responders were analyzed.
Results Among the responders, current smokers, past-smokers, and never-smokers were 17.3%, 16.4%, and 66.3% respectively. According to smoking status, the total KTSND-K scores of current smokers were significantly higher than those of past-smokers, and of never-smokers (17.7±6.6 versus 13.7±5.7, and 10.9±5.15, P<0.001). The total KTSND-K scores of males were higher than those of females, suggesting that males have a propensity for depending nicotine socially much more than females (13.2±6.2 and 11.7±5.7 respectively, P<0.05). And the total KTSND scores of the patients with lung cancer, medical students, nursing students, and high school students were 11.2±3.8, 14.9±4.8, 14.6±5.8 and 15.6±5.9 respectively. The scores of patients with lung cancer were significantly lower than non-cancer people(P<0.01). Our study suggested that the KTSND-K questionnaire could be a useful method to evaluate psychosocial aspects of smoking in patients with lung cancer and non-cancer people.
