温泉療法による気管支喘息に対する年間薬剤費の削減
Costs of drugs used for the treatment for 1 year were compared before and after spa therapy in 16 patients with asthma in relation to disease severity. Asthma severity was classified as : stage 1 (intermittent), 2 (mild persistent), 3(moderate persistent), and 4(severe persistent). 1. The total cost of drugs used for each pa-tient for 1 year clearty decreased in all groups. The % decrease of the costs of drugs in each group was 27.2% in patients with stage 1, 43.5% in those with stage 2 and 34.1% in those with stage 3-4 (mean 34.5% ). The reduction of the cost of bronchodilators was predominant in patients with stage 3-4, and the decrease in the cost of corticosteroids predominant in those with stage 2. The reduction of costs of antiallertgics, mucolytics, and antibiotics was predominant in patients with stage 2 and stage 3-4. The % reduction in the cost of corticostroids was remarkable in patients with stage 2. The % decrease in the costs of mucolytics and antibiotics was predomi-nant in patients with stage 2 and stage 3-4. The results obtained here suggest that the costs of drugs used for asthmatics could be reduced by long-term spa therapy, and the reduction of the costs was larger as asthma stage became more severe.気管支喘息16例を対象に,治療のために要した年間薬剤費が温泉療法により削減可能であるのかどうかについて,国際ガイドラインの重症度分類(stageト4)別に若干の検討を加えた。1.年間の総薬剤費は重症度別の全てのグループにおいて明らかに減少した.2.その削減率は,ステージ1で27.2%,ステージ2で43.5%,ステージ3-4で34.1%であり,その平均は34.5%であった。3.気管支拡張剤の薬剤費の減少はステージ3-4で高度であり,副腎皮質ホルモンの薬剤費の減少はステージ2で著明であった。また,抗アレルギー薬,去痩薬,抗生物質などの薬剤費の削減は,ステージ2および3-4で高度であった。4.削減率では,去壊薬,抗生物質の削減率が,2および3-4で著明であった。
以上の結果より,温泉療法により,気管支喘息の治療に必要な薬剤費は削減可能であること,そして,温泉療法による薬剤費の削減は職息の重症度が高い症例でより高度であることが示唆された
n-3系脂肪散を強化した食事療法が有効と考えられた肺気腫の一例
An effective treatment for the advanced stages of chronic obstructive pulmonary disease (COPD) has not been established yet. We report our recent experience of one patient with pulmonary emphysema treated by dietary supplementation of n-3 fatty acid for two months. He presented improvements in clinical symptoms and pulmonary function, and suppression of leukotriene B(4) generation by peripheral leukocytes. We consequently suppose that dietary treatment with n-3 fatty acids (perilla seed oil) may offer benefits for the treatment of pulmonary emphysema by competitively inhiabiting the conversion of arachidonicacid to leukotrienes and prostanoids.今回我々は,肺気腫の症例に対してn-3系脂肪酸を強化した食事療法をおこない,臨床症状,呼吸機能検査所見ともに速やかに改善を認め,同時に白血球のロイコトリエンB4産生能が著明に減少した一例を経験したので報告する。
症例は67歳,男性。主訴は労作時呼吸困難。【第一回目入院】3カ月間入院し,薬物療法,温泉を用いた理学療法を行った。自覚症状はやや改善が見られたが,呼吸機能検査所見の改善は得られなかった。【第二回目入院】1年後に再入院。n-3系脂肪酸強化食事療法も併用した。自覚症状および,呼吸機能検査上,FVC,FEV1.0,PEFなどに改善を認めた。n-3系脂肪酸はアラキドン酸代謝を通してロイコトリエン合成に関与すると推定されるが,経渦中に白血球のLTB4産生能の減少を認めた。この症例は肺気腫に対するn-3系脂肪酸強化食

長期間喫煙による気管支唱息,肺気腫の病態的変化
The influence of long-term cigarette smoking on the pathophysiology of chronic respiratory diseases with obstructive ventilatory dysfunction was discussed in
patients with asthma and pulmonary emphysema (PE). 1. In patients with asthma, significant differences in the pathophysiology of the disease were observed between
smokers and nonsmokers. A positive RAST score against inhalant allergens, bronchial hyperresponsiveness, and LTB4 generation by leucocytes were significantly more increased
in smokers than in nonsmokers. The values of FEV1/FVC and OLco were significantly more decreased, and % RV was significantly more increased in smokers than in nonsmokers. 2. In comparison of asthma with PE, IgE-mediated allergy was significantly more increased in smokers with asthma than in nonsmokers with asthma and in smokers with PE. The values of % FEV1, FEVl %, and % OLco were significantly higher in nonsmokers with asthma than in smokers with PE, however, the % OLco and % RV were not significantly different between smokers with asthma and those with PE. The
% LAA of the lungs on HRCT was larger in patients with PE than in smokers and nonsmokers with asthma. The results suggest that cigarette smoking influences the pathophysiology of asthma and PE.長期間喫煙による気管支喘息および肺気腫の病態的変化について若干の検討を加えた。1.気管支嘱喘息に関しては,喫煙例と非喫煙例との間に以下のような病態的特徴に差が見られた。吸入抗原に対する特異的IgE抗体の陽性率,気道過敏性,白血球のI:TB4産生能はいずれも,喫煙例で非喫煙例に比べ有意の亢進を示した。また,喫煙例では,非喫煙例に比べ,FEV1%や% DLcoは有意の低下,% RVは有意の増加傾向を示した。2.喘息と肺気腫の比較では,IgEにmediateされるア
レルギー反応は,喘息の非喫煙例や肺気腫(全て喫煙例)に比べ,喘息の喫煙例で有意の亢進が見られた。% FEVl,FEV1,% DLco値はいずれも喘息の非喫煙例で,肺気腫と比べ有意に高い値を示したが,% DLcoと% RV値には,喘息の喫煙例と肺気腫の間に有意の差は見られなかった。また,肺のHRCT上の% I.AAは,肺気腫において,喘息の喫煙例,非喫煙例いずれよりも有意に高い値を示した。以上の結果より,長期間の喫煙が喘息や肺気腫の病態に影響を与えることが示された
Effect of repeated Waon therapy on exercise tolerance and pulmonary function in patients with chronic obstructive pulmonary disease: a pilot controlled clinical trial
Purpose: Controlled clinical trials evaluating the efficacy of repeated Waon therapy for patients with chronic obstructive pulmonary disease (COPD) have yet to be conducted. The purpose of the present study was to evaluate whether repeated Waon therapy exhibits an adjuvant effect on conventional therapy for COPD patients.
Patients and methods: This prospective trial comprised 20 consecutive COPD patients who satisfied the criteria of the Global initiative for chronic Obstructive Lung Disease (GOLD) guidelines, stages 1–4. They were assigned to either a Waon or control group. The patients in the Waon group received both repeated Waon therapy and conventional therapy, including medications, such as long-acting inhaled β2 agonists, long-acting anticholinergics and xanthine derivatives, and pulmonary rehabilitation. The Waon therapy consisted of sitting in a 60°C sauna room for 15 minutes, followed by 30 minutes of being warmed with blankets once a day, 5 days a week, for a total of 20 times. The patients in the control group received only conventional therapy. Pulmonary function and the 6-minute walk test were assessed before and at 4 weeks after the program.
Results: The change in vital capacity (0.30 ± 0.4 L) and in peak expiratory flow (0.48 ± 0.79 L/s) in the Waon group was larger than the change in the vital capacity (0.02 ± 0.21 L) (P=0.077) and peak expiratory flow (−0.11 ± 0.72 L/s) (P=0.095) in the control group. The change in forced expiratory flow after 50% of expired forced vital capacity in the Waon group, 0.08 (0.01–0.212 L/s), was larger than that in the control group, −0.01 (−0.075–0.04 L/s) (P=0.019). Significant differences were not observed in the change in any parameters in the 6-minute walk test. Data are presented as means ± standard deviation or median (25th–75th percentile).
Conclusion: The addition of repeated Waon therapy to conventional therapy for COPD patients can possibly improve airway obstruction
気管支喘息症例における末梢血白血球のロイコトリエンC4産生能とロイコトリエン受容体括抗薬プランルカストの効果に関する検討
The correlation between the efficacy of 4-weeks administration with pranlukast, leukotriene receptor antagonist, and LTs generation by peripheral leukocytes
were evaluated in 18 patients with mild-persistent asthma. The efficacy of pranlukast administration was assessed by symptom, morning PEF and pulmonary function. Pranlukast were effective in 12/18(67%) patients. In those patients, LTC4
generation before pranlukast administration was significantly high, compared with that in pranlukast-ineffective patients. LTC4 generation decreased after 4-weeks administration
with pranlukast in effective patients. In ineffective patients, however, LTC4 generation increased after 4-weeks administration. LTB4 had shown no significant difference between effective and ineffective patients before administration, and LTB4 decreased after 4-weeks in both groups. Proport ion of peripheral eosinophi Is in
effective patients were higher than that in ineffective patients, however not significant. After 4-weeks, proportion of eosinophi Is was decreased in effective patients and
increased in ineffective patients. These findings suggest that pranlukast is effective for patients with high LTC4 generation and has the effect to suppress the accumulation
of eosinophils in such patients.軽症気管支喘息18例にロイコトリエン受容体桔抗薬プランルカストを4週間投与し,その効果と末梢血白血球からのLTC4,LTB4産生能の関係を検討した.プランルカストの効果は臨床症状,起床時ピークフロー値,肺機能の変化によって判定し,効果群,非効果群の2群に分類した.18例中12例(67%)の症例がプランルカスト投与により,臨床症状の軽減,ピークフロー値の増加,肺機能の改善が認められた.効果群におけるプランルカスト投与前のLTC4値は,非効果群のLTC4値に比較して有意に高値であった.4週間の投与後には
効果群ではLTC4値は減少し,非効果群では増加した.両群のLTB4値はプランルカスト投与前で有意な差は認められず,投与後には両群で減少した.投与前の好酸球分画は,効果群において非効果群に比べ高値であったが,有意な差は認められなかった.4週間の投与後,効果群においては好酸球は減少し,非効果群においては増加した.以上の結果より,プランルカストは末梢血白血球のLTC4産生能が高い症例において効果的であり,好酸球集積を抑制する作用を有すると考えられる
気管支喘息における気管支肺胞洗浄液中の細胞成分に対する加齢および副腎皮質ホルモンの影響
Effects of aging and glucocorticoid therapy on bronchoalveolar lavage (BAL) cells, particularly lymphocytes, neutrophils and eosinophils, were examined in 81 patients
with asthma.
1. The proportion of BAL lymphocytes tended to increase with aging in asthmatics under age 69 years, and the proportion was significantly higher in patients with asthma between the ages of 60 and 69 than in those under age 39 and between the ages of 40 and 49.
2. The proportions of BAL neutrophils and eosinophils were not related to aging.
3. The proportion of BAL lymphocytes was higher in patients without glucocorticoid therapy than in those with steroid-dependent intractable asthma (SOIA) in those under age 69 years. In patients between the ages of 50 and 59, the proportion of BAL lymphocytes was significantly higher in patients without glucocorticoids than in those with SOIA.
4. The proportion of BAL neutrophils was higher in patients without glucocorticoid therapy than in those with SOIA, and the difference was significant in patients between the ages of 60 and 69.
5. The proportion of BAL eosinophils was not related to glucocorticoid therapy. These results suggest that the proportion of BAL lymphocytes and neutrophils is affected by aging and glucocorticoid therapy, but not BAL eosinophils.気管支喘息81例を対象に,気管支肺胞洗浄(BAL)液中の細胞成分,特にリンパ球,好中球および好酸球に対する加齢および副腎皮質ホルモ
ンの影響について検討を加えた。
1.BAL液中のリンパ球頻度は,69才以下の症例では加齢とともに増加する傾向を示し,60-69才の年齢層では,39才以下および40-49才の年齢層の症例に比べ有意に高い値を示した。
2.BAL液中の好中球および好酸球頻度と加齢との間には関連が見られなかった。
3.BAL液中のリンパ球頻度は,69才以下の症例では,ステロイド依存性重症難治性喘息(SDIA)に比べ,ステロイド非使用例で有意に高い値を示し,50-59才の年齢層ではその差は有意であった。
4.BAL液中好中球頻度は,ステロイド非使用例に比べSDIA症例において高い値を示し,60-69才の年齢層ではその差は有意であった。
5.BAL液中好酸球頻度は,ステロイド使用の有無との関連は見られなかった。これらの結果は,BAL液中リンパ球および好中球頻度は加齢や副腎皮質ホルモン投与の影響を受けるが,BAL液中好酸球額度には影響しないことを示唆している
高齢者気管支喘息における気道過敏性と温泉療法
Clinical effects of spa therapy were examined in 150 patients with asthma in relation tobronchial hyperresponsiveness and patient age. 1. The efficacy rate of
spa therapy was larger as the patient age was higher: the rate was 73.3% in patients under age 49, 81.8% in those between the ages of 50 and 59, 86.4% in those between
the ages of 60 and 69, and 90.6% in those over age 70. The mean of efficacy rates was 83.3% in all subjects.
2. The bronchial hyperresponsiveness (BH) was lower as patient age was higher: the BH in patients between the ages of 60 and 69 and in those over age 70 was significantly
lower compared to the BH in those under age 49 (p < O.OOl).
3. Clinical effects of spa therapy tended to be lower in patients with increased bronchial hyperresponsiveness. The bronchial hyperresponsiveness showed a tendency to decrease after spa therapy in whom the therapy was effective, however, the BH did not change in patients with slight or no efficacy during spa therapy.1.温泉療法では,年齢が高くなるほどその有効率も高くなると言う傾向が見られ、49才以下の症例では73.3% ,50-59才の症例では81.8% ,
60-69才の症例では86.4% ,70才以上では90.6% であり,全症例の平均有効率は73.3% であった。
2.気道過敏性は,年齢が高くなるほど低下する傾向が見られ,60-69才および70才以上の症例の気道過敏性は,49才以下の症例と比べ有
意に低い値を示した(P < 0.001)。
3.温泉療法の臨床効果は,気道過敏性が強くなるにつれて低下する傾向が見られた。また,温泉療法の著効例や有効例では,治療により
気道過敏性が低下してくるが、やや有効例や無効例では,気道過敏性はほとんど変化しないことが示された
Characteristics of the elderly in high - resolution computed tomography lung densitometry
To determine the characteristics of the elderly in high - resolution computed tomography (HRCT) lung densitometry, mean lung density (MLD) and relative area of the lungs showing attenuation values less than -950 HU (RA(950)) on HRCT were
evaluated in nonsmoking control subjects (n = 80) and patients with asthma (n = 80) in relation to their age and pulmonary function. MLD was significantly decreased, and
RAW was significantly increased with increasing age in both asthmatics and controls.
The MLD values were significantly lower in asthmatics compared with controls in subjects aged between 60 and 69 years and over age 70. RAgsov alues were significantly
higher in asthmatics compared with controls in subjects aged between 50 and 59 years, between 60 and 69, and over 70. % FEV(1) and FEV(1) / FVC were significantly decreased
in elderly asthmatic patients over 70 years of age compared with the values in those under 49. Percent residual volume (% RV) was significantly larger in patients over 70 years of age than in those between 50 and 59, and under 49 years. RAW was significantly larger in patients with steroid-dependent intractable asthma (SDIA) between 50 and 59 years of age, and between 60 and 69 compared with RA 950 in those without
SDIA. However, RAW did not differ significantly between SDIA and non-SDIA in patients over age 70. The results suggested that in % LAA of the lungs on HRCT was significantly increased in the elderly subjects with and without asthma, and it was significantly higher in the elderly asthmatics than the elderly controls.高齢者の病態的特徴を明らかにするために,健常者80例および非喫煙喘息患者80例を対象として,平均肺CT値(MLD)ならびに高分解能CT(HRCT)による-950HU以下の肺low attenuation area(RA950)を評価し,年齢及び肺機能との関連を検討した。
1.健常者,喘息患者いずれにおいても年齢とともにMLDは有意に減少し,RA(950)は有意に増加した。MLDは,60-69歳と70歳以上の年
齢層において,健常者に比して喘息患者で有意に低値を示した。RA(950)。は,50-59歳・60-69歳・70歳以上の年齢層において,健常者に比して喘息患者で有意に高値を示した。
2.喘息患者において,1秒量(% FEV(1))および1秒(FEV(1)/ FVC)は,49歳以下の年齢層に比して70歳以上の年齢層で有意に低値を示した。一方,残気量(% RV)は,50-59歳ならびに49歳以下の年齢層に比して70歳以上の年齢層で有意に高値を示した。
3.50-59歳および60-69歳の年齢層では,RA(950)は,ステロイド依存性重症難治性喘息(SDIA)患者において非SDIA患者に比して有意に高値を示した。しかし,70歳以上の年齢層では両者に有意の差は認められなかった。これらの結果より,HRCT上の肺low attenuation areaは高齢者において有意に増加すること,さらに嘱息患者の方が健常者に比してより高値を示すことが示唆された
Spa therapy for patients with respiratory disease. Clinical efficacy and action mechanisms of the therapy on asthma
呼吸器疾患に対する温泉療法は,最近の22年間にわたり行われてきた結果,その有用性は十分明かとなっている。この22年の間に,温泉療法を受ける対象もかなり変わってきており,例えば気管支喘息では,ステロイド依存性重症難治性喘息の全症例に対する割合は明
らかに低くなってきている。また,COPDでは最近全症例に対する肺気腫の割合も,また症例数も著明に増加しつつある。一方,温泉療法を求めて来院される症例数は年ごとに増加する傾向にあり,初期の5年間と比べ,最近の5年間では,気管支喘息では8.2倍,また肺気腫では
34.8倍の増加が観察されている。呼吸器疾患に対する温泉療法の作用機序としては,直接作用として,自・他覚症状の改善,換気機能の改善,気道過敏性の改善,気道抵抗の低下,肺の過膨脹の改善,過分泌の抑制などが観察される。一方,間接作用としては,副腎皮質機能の改善,精神的リラックス,抗酸化酵素であるSOD活性の克進などが観察され,これらの間接作用も気管支喘息の病態改善に重要な役割を果しているものと考えられる。Spa therapy which has been performed for patients with respiratory disease, particularly for those with asthma and pulmonary emphysema for last 22 years demonstrates that spa therapy is effective for asthma and pulmonary emphysema.
The characteristics of patients with respiratory disease has been changing during last 22 years : the frequency of patients with steroid-dependent intractable asthma (SDIA) tends to decrease inspite of an increase in number of those with asthma who has been admitted at Misasa Medical
Center for spa therapy.
The frequency and number of patients with pulmonary emphysema has been increasing in recent years. Spa therapy has direct action mechanism for airways such as improvement
of subjective and objective symptoms, and improvement
of ventilatory function, bronchial hyperresponsiveness, and hyperinflation of the lungs. The therapy has also indirect action mechanism for other organs excluding the airways
such as improvement of suppressed function of adrenocortical glands, psychological relaxation, and an increase in SOD activity. These indirect actions of spa therapy play an important role in treatment of the disease
サーモグラフィーによる体表面温度の測定 3.体表面温度の回復率と末消血流量との相関
The body surface peripheral circulation in 12 cases, including 9 patients with diabetes mellitus who were suffering coldness, numbness or pain in their feet, and 3
healthy volunteers was examined using Laser-Doppler blood flowmetry. At the same time, the body surface temperature was estimated by thermography. Thermographic results were analyzed quantitatively by calculating a recovery ratio as : Recovery ratio = [Total counts of thermography(Pixels) over temperature (T) after cold loading] ÷ [Initial counts over T before cold loading] x 100(%). The recovery ratio and the blood flow were correlated, r=0.68, p<O.01. The peripheral circulation of 16 patients with diabetes mellitus was observed at three different conditions including, l)placed at room temperature at 20℃for 15 min, 2) submerged and warmed for 5 min in a hot bath at 36℃(i.e. hot loading), and 3) submerged and cooled for 5 min in a water bath at 20℃ (i.e. cold loading). Three different baseline temperatures, 26℃, 27℃ and 28 ℃, were used in processing the thermographic results into pictures. The highest correlation (r=0.59, p=0.0002) was
obtained under the condition of cold loading using a baseline temperature limitation of27℃.The difference ratio (%) of blood flow was calculated as the blood flow at cold
loading divided by the blood flow at hot loading in these 16 patients. The difference ratio of the blood flow and the recovery ratio of thermography were correlated,
r=0.46, p<O.OOO1. We found a strong correlation between the results of Laser-Doppler blood flowmetry and one of thermographic methods used to monitor peripheral circulation in patients with diabetes mellitus. Cold loading using a baseline temperature limitation of 27℃
were recommended for further examinations. Patients with low blood flow as well as with large differences in their peripheral circulation between cold loading and hot loading had severe coldness in their body surface temperature. We showed the usefulness of the results of thermography, when quantified by picture processing using computer software, in relation with the results of Laser-Doppler blood flowmetry.末梢神経障害を有する糖尿病患者の末梢循環障害の程度を数量的に検討する目的で、下肢に冷感ならびにしびれ感または疼痛を訴える糖尿病患者9症例と健常ボランティア3例の計12例(平均年齢59歳)についてサーモグラフィーを用いて体表面温度を測定した。更に,サーモグラフィーで得られた結果と末梢皮膚血流量をレーザードプラー血流計を用いて測定して得られた結果と比較した。サーモグラフィーによる測定で得られた結果は回復率として数量化して表示された。回復率の算出方法は回復率= [冷水負荷後の特定温度27℃以
上の体表面温度のサーモグラフィーのPixelの総数]÷ [冷水負荷前の特定温度27℃以上の体表面温度のサーモグラフィーのPixelの総数]×100%で求めた。レーザードプラ-血流計を用いて測定して得られた末梢血流量は左右それぞれ5カ所,計10カ所の測定値の平均で表示した。その結果,末梢皮膚温度の回復率と末梢皮膚の血流量との問には正の相関関係(r=0.68,p<0.01)が認められた。次に,末梢皮膚血流量について,室温20℃安静15分後,温水36℃浸水負荷10分後,冷水20℃浸水負荷30分後の異なる3条件について、またサーモグラフィーで得られた結果を,画像処理の過程で用いられた,26℃,27℃,28℃の3つの異なる特定温度との関連について検討を行なった。対象は,下肢に冷感ならびにしびれ感または疼痛を訴える糖尿病患者16症例(平均年齢69歳,平均HbAIC9.6%)について測定した。その結果,末梢皮膚
血流量は冷水20℃浸水負荷30分後に測定して得られた結果と,回復率は特定温度27℃で画像処理して得られた結果とが最も相関が高い(r=0.59,p=0.0002)ことが示された。`次に,相関が高い条件は,室温20℃安静15分後に血流量を測定した場合(r=0.483,p=0.0002)であった。そして温
水36℃浸水負荷10分後に測定して得られた結果とが最も相関関係が低い結果となった。更に,冷水20℃浸水負荷30分後に測定して得られた結果を温水36℃浸水負荷10分後に測定して得られた結果で割った比を%で表示したところ回復率とこの比との間には正の相関関係(r=0.46,p<0.0001)が認められた。このことから,温水36℃負荷時と,冷水20℃負荷時との差が大きい患者
において末梢皮膚温度の低下が著しいことが示された。これまで悲観血的に測定されてきたサーモグラフィーによる末梢循環の数量的評価の試みは,レーザー血流計による結果と組み合わせることで,両者の間に正の相関関係が示されたことにより,今後,数量化された客観的評価を可能にした
