Characteristics of asthma classified by a score relating to clinical findings and examinations

Twenty six patients with bronchial asthma was classified by clinical symptoms and singns (clinical diagnosis), and the classification by clinical diagnosis was compared with the classification by a score calculated from clinical findings and examinations (score diagnosis). 1. Of 12 subjects with type Ia classified by clinical diagnosis, 8 cases with 0 to 49 ml/day of expectoration were evaluated as type Ia by score diagnosis. While four type Ia cases with 50 to 99ml/day of expectoration were calssified as type Ib by score diagnosis. The increased incidence of eosinophils in bronchoalveolar lavage fluid (BALF) of these four cases was similar to the incidence in type Ib cases with hypersecretion. 2. All of 6 subjects with type Ib by clinical diagnosis were estimated as type Ib by score diagnosis. 3. Of 8 cases with type II by clinical diagnosis, 7 cases were assessed as type II by score diagnosis. One case with type II by clinical diagnosis and with the score of 10 points was evaluated as questionable type II by score diagnosis.

気管支喘息36例を対象に,臨床病態による喘息の分類（臨床診断）を試み,この分類と臨床所見および臨床検査より求めたスコアーによる分類（スコアー分類）との比較検討を行った｡1.臨床分類でIa.単純性気管支攣縮型と診断された12症例のうち,1日喀痰量0-49mlの8症例は,スコアー分類では同様にIa.型と分類された｡一方,1日喀痰量50-99mlの4症例はスコアー分類ではIb.型（気管支攣縮+過分泌型）と分類された｡これら4症例のBALF中好酸球増多はIb.型に類似した病態であった｡2.臨床診断によりIb.型に分類された6症例はいずれもスコアー診断でもIb.型と分類された｡3.臨床診断によりII.型（細気管支閉塞型）と分類された8症例のうち,7症例はスコアー診断でもII.型と分類されたが,1症例はスコアー10でII.型の診断基準に合わず,questionable II.型と診断された｡
