Awareness of COPD in a High Risk Korean Population

PURPOSE: Increased awareness and understanding of chronic obstructive pulmonary disease (COPD) is an important aspect of disease management. The aim of this study was to explore COPD awareness among smokers participating in a smoking cessation program. MATERIALS AND METHODS: Face-to-face interviews were conducted with 289 subjects in three smoking cessation clinics, using a structured questionnaire. RESULTS: A total of 68.2% of subjects had COPD-related symptoms, and 19.7% were in poor health. Only 1.0% of the subjects knew that COPD was a respiratory disease. A total of 2.4% of subjects had been diagnosed with COPD and received treatment. Television was the most common source of information about COPD, with 57.1% of the subjects receiving information in this way. After being informed about COPD, smoking-cessation willingness increased in 84.1% of the study group. It increased in 86.3% of the subjects without awareness of COPD and in 81.2% of subjects with COPD-related symptoms. CONCLUSION: We found that awareness of COPD is very poor among current smokers in Korea. Many smokers perceived their health status as good, despite the presence of COPD-related symptoms. As the level of smoking-cessation willingness was different between those with and without awareness of COPD or COPD-related symptoms, a personalized education program with various educational tools may be needed to enhance awareness of the disease and to motivate smokers to quit.

Awareness of chronic obstructive pulmonary disease in current smokers: a nationwide survey

BACKGROUND/AIMS: Cigarette smoking is the most common risk factor for chronic obstructive pulmonary disease (COPD). However, few studies of the attitudes toward COPD of smokers, the group at risk of developing this condition, have been conducted. The purpose of this study was to explore the awareness of and attitudes toward COPD of current smokers. METHODS: The sample consisted of 502 individuals aged 45 and older from throughout Korea who smoked at least 10 packs of cigarettes per year. Telephone interviews using a structured questionnaire were conducted with respondents. RESULTS: First, we evaluated the health status of subjects, finding that 45.4% considered themselves to be in good health. We also asked about COPD-related symptoms, and 60.6% of subjects reported such symptoms. However, only 1.2% of subjects had been diagnosed with or treated for COPD, only 0.4% spontaneously mentioned COPD as a respiratory disease, and only 26.5% recognized COPD as a respiratory disease after seeing a list of such diseases. Television ranked as the top source of information about COPD. The willingness of 45.0% of subjects to stop smoking increased after being informed about COPD. CONCLUSIONS: Despite having COPD-related symptoms, most smokers did not know that COPD is a respiratory disease. The attitudes of smokers toward COPD and smoking cessation varied according to socioeconomic status. In summary, a continuous effort to increase the awareness of COPD among smokers is needed. Additionally, strategies tailored according to different socioeconomic groups will also be necessary.

A Case of Hyponatraemic Seizure Following Terlipressin Therapy for a Variceal Hemorrhage in a Patient with Liver Cirrhosis / 대한내과학회지

Terlipressin has splanchnic vasoconstrictive effects, and is generally used for the management of gastroesophageal variceal bleeding secondary to liver cirrhosis. Terlipressin is a synthetic arginine vasopressin (AVP) analog containing a nonapeptide sequence. Terlipressin has increased selectivity for the V1 receptor, compared with AVP; hence, it is considered to be a safe vasoconstrictor. However, side effects such as hyponatremia and seizure, although very rare, have been reported. Hyponatremia related to terlipressin may be caused by the syndrome of inappropriate antidiuresis (SIAD), which is a disorder of sodium and water balance characterized by hypotonic hyponatremia without elevation of the antidiuretic hormone level. Here, we report a case of hyponatremic seizure induced by an infusion of terlipressin in a 52-year-old female who had isolated gastric variceal bleeding secondary to alcoholic liver cirrhosis.
