Methods: One hundred seventy patients who were followed-up for asthma treatment at the department of pediatrics of CHA Bundang Medical Center were enrolled in this study. We conducted the questionnaire regarding coexistence of rhinitis, childhood asthma control test (C-ACT), and the basic lung function test. The patients were classified as allergic rhinitis group and nonallergic rhinitis group according to the response to 11 common inhalation and food allergens, and assessed the degree of asthma control and the severity of rhinitis. Results: One hundred thirty patients (73%) were found to have rhinitis. Of these, 79 patients (53%) had allergic rhinitis and 34 patients (20%) had nonallergic rhinitis. The allergic rhinitis group was older than the nonallergic rhinitis group or the nonrhinitis group (7.73 ± 2.85 vs. 5.97 ± 2.48 vs. 6.12 ± 2.70, P< 0.001). Nasal itching sense was more prevalent in the allergic-rhinitis group than in the nonallergic rhinitis group (3.23 ± 1.90 vs. 2.44 ± 1.56, P= 0.036). There was an inverse correlation between the rhinitis and C-ACT (r = 0.329, P< 0.05). Of note, nasal obstruction symptom was highly correlated with C-ACT (r= 0.334, P< 0.001). Conclusion: Allergic rhinitis and nonallergic rhinitis were highly prevalent in the pediatric patients with asthma and both of them had a significantly adverse impact on asthma control by rhinitis-itself. Therefore, regardless of atopic status, clinicians should focus on relieving rhinitis symptoms.

Kwon EB, et al. Relationship between the asthma and rhinitis 나는다증상천식 (multi-symptom asthma) 의위험이증가한다. 8) 그러나알레르기비염과달리식품감작, 습진발생, 총 immunoglobulin E (IgE), 혈중호산구수, fractional exhaled nitric oxide, 기관지과민성등과는상관성이없다. 7) 이는알레르기염증반응을뛰어넘는상기도와하기도의연관성에기인하는것으로알려져있다. 7) 이렇게알레르기비염과비알레르기비염이천식과연관되어있다는것은성인에서는잘알려져있지만소아천식환자를중심으로비염동반의유병률, 비염종류에따른천식조절과의상관성에대해서는잘알려져있지않다. 이에본연구는천식을가진소아환자에서알레르기비염과비알레르기비염의유병률과증상, 중증도의차이를확인하고자하였다. 또한비염과천식조절정도의상관성을보고자하였다. 대상및방법 1. 연구대상 2011년 5월부터 2012년 12월까지분당차병원소아청소년과로기관지천식을진단받고치료, 추적관찰을받기위해내원한환자를대상으로하였다. 본연구에서모든환자는폐활량 (spirometry) 과충격진동법 (impulse oscillation system) 폐기능검사를실시하였다. 또한피부단자시험을이용한특이 IgE 검사를시행하였으며, 비염유무에대해조사하였다. 더불어알레르기전반에대한가족력, 과거력과환경요인에대해알아보고자구조화된설문지를사용하여조사하였다. 설문내용에는형제자매수, 알레르기가족력, 출생력, 알레르기질환의의사진단여부, 코골이, 폐렴, 모세기관지염과천식등의질환으로인한입원력, 애완동물소유여부, 가족들의흡연여부, 거주지형태에대해질문한내용이포함되었다. 설문지는환자보호자가작성하도록하였다. 비염의조절정도는시각적비율척도 (visual analog scale, VAS) 9) 로, 천식조절정도는소아천식조절점수 (childhood asthma control test, C-ACT) 설문지 10) 를활용하여평가하였다. 이모든검사와설문조사에응한환자들만을대상으로연구를진행하였다. 연구시행전 4주이내에상기도나하기도의호흡기감염의증상을보이거나최근 6개월내에천식의급성악화로전신스테로이드를투여받았던경우는연구대상에서제외하였다. 2. 특이 IgE 검사알레르겐양성여부는피부단자시험을활용하였다. 총 11종 (Allergo Pharma, Steinbeck, Germany) 의주요흡입또는식품항원을사용하였다. 이에는집먼지진드기두종류 (Dermatophagoides pteronyssinus, Dermatophagoides farina), 동물털 mix (cat, dog, hamster, guinea pig, rabbit), 나무류 I (alder, hazel, poplar, elm, willow), 나무류 II (birch, beech, oak, plane), 곰팡이 mix (Alternaria tenuis, Botrytis cinerea, Cladosporium herbarum, Curvularia lunata, Fusarium moniliforme, Helminthosporium halodes), 잔디류 (velvet, orchard, rye, timothy, kentucky blue, meadow fescue), 잡초류 (mugwort, nettle, dandelion, plantain), 우유, 달걀, 땅콩이포함되었다. 알레르겐으로단자검사시행한 15분후팽진의크기가 3 mm 이상이면양성으로판정하였다. 11) 3. 용어정의천식의진단은만성기침, 호흡곤란, 천명의전형적인증상을반복적으로보인경우로하였다. 아토피천식은비염유무와상관없이특이 IgE가양성인경우로하였고, 특이 IgE가음성인경우에는비아토피천식으로하였다. 비염은감기없이평상시콧물, 코막힘, 재채기또는코간지러움을호소하는경우로하였다. 알레르기비염은비염증상이있으면서항원특이 IgE검사에양성일때, 비알레르기비염은비염증상은있으나특이 IgE가음성일때로하였다. 12) 그러므로대상군을알레르기비염, 비알레르기비염과비염음성군으로나누어연구하였다. 4. 비염중증도비염환자에서비염증상의지속기간, 수면방해, 일상생활이나운동의방해, 기타성가신증상과전반적인증상의중증도등에대한항목을조사하였으며이를토대로 allergic rhinitis and its impact on asthma (ARIA) 가이드라인에따라비염중증도를분류하였다. 13) 5. 비염과천식조절정도비염환자에서재채기, 콧물, 코간지러움과코막힘의조절정도를조사하였다. 각항목에대해경증 1점부터중증 7점까지점수를주고이에대한점수를합산하여 VAS 점수를구하였다. 9) 소아천식조절정도는 Liu 등 10) 이검증한 C-ACT의한국어번역본을저작권소유자인 GlaxoSmithKline (GSK) 로부터허락을받아사용하였다. C-ACT 는소아가직접선택하는 4개의항목과부모가선택하는 3개의항목으로구성되어있으며, 각각의항목들은천식증상, 기침, 천명, 야간및주간증상에대한질문으로이루어져있다. 소아가선택하는 4개의항목은중증 1점부터경증 4점까지의점수를주었으며, 부모가선택하는 3개의항목은중증 1점부터경증 5점까지의점수를주어 7개항목의점수를합산하여총점수를구하였다. 6. 폐기능검사폐활량과충격진동법은 MS-IOS Digital instrument (Erich Jaeger AG, Würzburg, Germany) 를사용하였다. 먼저충격진동법에의한기도저항 (resistance at 5 Hz, Rrs 5) 과유도저항 (reactance at 5 242 http://dx.doi.org/10.4168/aard.2013.1.3.241

권은별외 소아천식환자에서비염과천식과의관계 의소아천식의비염동반율은 60 80% 라고보고한연구는 19) 피부단자시험없이코간지러움, 재채기, 코분비물의증가, 코막힘등의증상으로알레르기비염을진단하였으며, 3세전후소아천식환자를대상으로한연구에서도 18) 비강내점막상태와비염증상의지속여부로알레르기비염을진단하여흡입항원에대한감작도를진단기준에포함시키지않았다. 22) 이는통상적인알레르기비염의정의 19) 와다르며비알레르기비염이알레르기비염으로진단되었을가능성을배제할수없다. 이와달리 Hamouda 등 23) 의연구에서는 237명의소아천식환자에서 3 5세는알레르기비염이 39%, 6 11 세는 63%, 12 18세는 67% 였다. 흡입항원에감작된환자비율이 6 세이후에통계적으로의미있게증가하였는데, 이는평균연령이 6.8세의환아들을대상으로조사한본연구의알레르기성비염의 53% 와유사한결과이다. 본연구에서비염증세가없으며감작만있는군과감작이없는군의나이가통계적으로의미있는차이를보인것은감작이나이와함께역동적으로변화하며이로인해알레르기비염진단율에차이가난것이라여겨진다. 다만, 본연구에서비경검사나비즙세포검사 (nasal cytology) 를시행하지않았기에비염이있지만현재증상이없는환자들이포함되지않아진단율이낮아졌을가능성이있다. 2세에서 10세천식이있는 130명의소아를대상으로한연구 18) 에서비경검사로전형적인알레르기비염의코점막소견을보이나코증상이없다고대답한환자의비율은 11.9% 였다. 이와반대로보호자가지속적인코증상을호소한환자중 22.3% 는비경검사에서알레르기비염의증거가보이지않았다. 이는비염의유병기간이짧고알레르기항원노출이없는기간에비강이정상소견으로보일수있기에나타난결과이다. 24) 또한보호자가작성한설문지에기초한알레르기비염진단의양성예측도는 81.7%, 음성예측도는 42.9% 였다. 18) 이런점을고려한다면, 향후알레르기성비염진단에특이 IgE 검사와함께비경이나비즙세포검사를시행하여진단의정확도를높인연구가필요하다. 2. 알레르기비염과비알레르기비염의증상차이성인에서알레르기비염과비알레르기비염의증상차이에대한보고는많이있어왔다. 25) 한연구자는알레르기비염에서코간지러움, 재채기와다른알레르기증상이동반하는경우가흔하고, 후비루는비알레르기비염에서더흔하다고보고하였다. 26) 다른연구자는, 27) 알레르기비염에서증상이더심하고알레르기결막염이동반되는경우가많으나, 비알레르기비염의경우두통등의증상이동반되는경우가더많다고기술하였다. 14세미만의소아를대상으로한연구에서성인과마찬가지로코간지러움, 재채기, 눈증상은알레르기성비염에서더흔하고, 부비동염과상기도폐쇄는비알레르기성비염에서더흔하였다. 28) 이런연구결과는알레르기비염환자에서코간지러움증상이더뚜렷한것으로나타난본연구와유사하다. 코간지러움증상의차이는연구대상군이흡입항원감작 률이증가하는시기 29) 와유사하기에만성비염의염증형태인코막힘증상 30) 보다간지러움이특징적으로나타난것이아닌가한다. 천식조절점수, 1초간강제호기량, 충격진동검사기로측정한 Rrs 5, Xrs 5 에서두군간의유의한차이가없었는데, 이는천식환자들을대상으로하였기때문에나타난결과라고여겨진다. 아토피천식과비아토피천식의기본폐기능에서차이가없었다는보고 31,32) 는본연구결과와일치하는소견이다. 천식이알레르기비염과비알레르기비염모두와비슷한연관성을가지며천식과비염의상관성은감작여부보다는상하부호흡기관의염증반응의연관성이더중요하게작용하여나타난결과 7) 로보여지며이때문에기본폐기능또한감작처럼두군에서차이가나타나지않는것이라해석할수있다. 32) 3. 비염중증도와천식조절 ARIA 가이드라인에따른비염중증도를알레르기비염과비알레르기비염에서분류를하였을때두군간에의미있는차이는없었다. 기존의연구에서는 33) 천식환자에서동반하는알레르기비염중가장비율이높은것은경증간헐적비염이라하였고, 3 18세소아환자들을대상으로한연구 23) 에서도경증간헐적비염비율이높았다. 이는중등도-중증간헐적비염이알레르기비염과비알레르기비염에서가장높은빈도를차지한본연구와차이가있다. 그러나경증간헐적비염빈도도비슷한유병률을보였는데이는연구대상군의차이에의한결과로생각된다. 비염의중증도에따른천식조절점수는차이가없었으나이는 18세에서 60세의성인을대상으로한연구 34) 에서비염중증도가높을수록천식조절이어려웠다는연구결과와일치하지않는다. 4. 비염과천식의조절상관도알레르기비염뿐만아니라비알레르기비염모두에서비염조절점수가높을수록천식조절점수가낮아지는경향성을보였다 (r = 0.329, P<0.05). 이는동반된비염증상을조절해야천식의조절이잘되는것을의미한다. 7) 알레르기비염과천식의연관성에대한기전으로전신염증반응과더불어구강호흡에의한알레르겐의흡입의증가가제시되고있다. 35) 그러므로비염증상중코막힘에의한구강호흡이비염과천식의연관성에중요한기전이될것으로여겨진다. 본연구에서도비염증상중코막힘이다른비염증상보다천식조절정도와더높은상관성을보였다 (r = 0.334, P<0.001). 따라서소아천식환자에서알레르기비염과비알레르기비염의증상을모두조절해야하며, 특히코막힘에의한구강호흡의조절이중요하다. 5. 한계와연구의장점본연구의제한점으로단일병원내천식으로치료받은소아환 http://dx.doi.org/10.4168/aard.2013.1.3.241 245
Kwon EB, et al. Relationship between the asthma and rhinitis 자를대상으로한단면적인연구로비염과천식의인과관계를확 인할수없었다는점이다. 또한상대적으로연구대상의숫자가적 었고비염의진단시환자본인이호소한증상에기초하거나보호 자가작성한설문지내용에근거하여진단하였기에코점막의상태 등에대한객관적인평가가이루어지지못했다. 또한소아의비알레 르기비염의주요한요인인감염성비염, 비부비동염의동반여부 등, 좀더세분화된비알레르기비염의구분과분석이이루어지지 않았다. 그러나저자들은소아천식환자에서폐활량과충격진동 법의폐기능검사를모두시행하였고, 소아에서알레르기비염과비 알레르기비염의중증도를비교하여그차이점과유사점을밝혀내 려고한것에의미가있다하겠다. 결론적으로, 알레르기비염과같이비알레르기비염도상부호흡 기염증반응과더불어코폐쇄에의한하부호흡기도에영향으로 천식조절에영향을주는것을알게되었다. 그러나두질환에서기 본폐기능차이가없었고이는아토피유무가천식의중증도에영 향을주지않는것으로여겨진다. 하지만비염조절이안될수록천 식조절에어려움이있고, 이는장기적인관점에서환자의천식단 계를악화시키는것은아니나, 환자의주관적인증상및삶의질, 치료의순응도에는영향을미칠수있다. 따라서, 천식과의밀접한 상관성이논의되어왔던알레르기비염뿐만아니라비알레르기비 염도천식의조절에영향을주기에소아천식환아에서도비알레 르기비염도적극적으로치료하여비염증상을조절및개선해야 한다는점을시사한다.
