Abstract
Description
・世界乾癬デー(World Psoriasis Day)の連盟(consortium)によれば、世界全体で1億2,500万人が乾癬である。
乾癬の処置に最も多く使われている局所剤は局所コルチコステロイドであり、低度から中等度の乾癬病変の制御だけでなく、迅速な作用発現に極めて有効である場合がある。局所コルチコステロイドは皮膚細胞の増殖を遅延させ、炎症を軽減する。ステロイドの中には作用は強いが、頻繁に使用しすぎると皮膚損傷を引き起こすものもある。ステロイドは、粉末、噴霧、ゲル、クリーム、さらに頭皮に使用される泡状のビヒクルなど広範囲のビヒクルで利用できる。しかしながら、局所コルチコステロイドの最も厄介な特徴の1つは、患者がタキフィラキシー、すなわち当初は非常に有効であった医薬品が、長期的な使用に伴い有効性を失う現象を起こすことである。
UVB処置は、医療機関で医師の指導の下、あるいは医師の指示により購入した家庭用機器を使用して、皮膚に人工UVB光源(315〜280nm)を定期的に一定時間当てる。紫外線B(UVB)(315〜280nm)は表皮に吸収され、乾癬に有益な作用を発揮する。ナローバンドUVB(311〜312nm)は、乾癬に最も有用であるUVBスペクトルの一部である。
従来型の3つの主要な全身処置剤としてメトトレキサート、シクロスポリンおよびレチノイドがある。メトトレキサートおよびシクロスポリンは免疫抑制剤であり、レチノイドはビタミンAの合成形態である。特に乾癬用に承認されているわけではないが、これら以外の薬剤が有効であることも明らかになっている。そうした薬剤として、代謝拮抗剤チオグアニン、細胞傷害性薬物ヒドロキシ尿素、スルファサラジン、免疫抑制薬ミコフェノール酸モフェチル、アザチオプリンおよび経口タクロリムスが挙げられる。これらの薬剤はすべて、他の処置剤が効果を発揮しない場合、乾癬の効果的な処置に使用されている。さらにドイツでは重度の乾癬の処置にフマル酸エステルが20年以上使用されているが、他の多くの国々では承認されていない。
親水性ポリマー材料の水和ヒドロゲルの場合、親水性ポリマー材料は、ゲルの総重量に対して少なくとも1%、好ましくは少なくとも2%、一層好ましくは少なくとも5%、なお一層好ましくは少なくとも10%、あるいは少なくとも20%、望ましくは少なくとも25%、なお一層望ましくは少なくとも30重量%の濃度で存在することが望ましい。さらに多くの量、ゲルの総重量に対して最大約40重量%を使用してもよい。
好ましいポリマー材料の1つとしてポリビニルアルコール(PVA)がある。PVAには、たとえば無毒であるなど皮膚処置に使用するのに都合がよく許容可能な特徴がある。PVAはさらに取扱いおよび使用が容易で、PVA水溶液が乾燥するとすぐにフィルムを形成し、生じたフィルムも取扱いやすい。PVAはさらに入手しやすいうえ安価である。固体材料の形成、たとえばフィルムの形成の際に架橋結合の必要はないが、任意に架橋結合を利用してもよい。PVAは、材料の物理的性質に影響する分子量および加水分解の程度に応じて広範囲のグレードで入手可能である。個々の使用目的に適した所望の特性を持つポリマー生成物を生成するのに適切なグレードのPVAは、容易に選択することができる。たとえば、皮膚用包帯剤に使用する場合、ほぼ完全に加水分解された(98〜99%加水分解された)分子量が100,000〜200,000の範囲のPVA、たとえばSigma−Aldrich社製の非架橋型コード36,316−2の形態のPVA、さらに分子量が31,000〜50,000(87〜89%加水分解)のPVA、たとえばSigma−Aldrich社製のコード363073の形態のPVAを使用すると好結果が得られている。
本試験は、被験者4例の非盲検内部対照試験(internally controlled study)であった。
試験用材料は、使用時に皮膚上で混合されて一酸化窒素を生成する2成分水性ゲルとした。
a.26mMの塩化カルシウムおよび100mMのα−モノチオグリセロール、pH4.2を含む水性carbopol 974P NFポリマー(4.5%w/w)。
a.26mMの塩化カルシウム、pH4.2を含む水性carbopol 974P NFポリマー(4.5%w/w)。
以下の方法を用いて乾癬性プラークの状態の評価およびスコア化を行った:「乾癬症状の重症度」=[L×W]×[E+T+S]
ここで[L×W]はcm2単位の患部プラークの全体の領域(長さ×幅)を表し、
Eは紅斑の臨床医による評価を表し(0〜5の等級を使用)、
Tはプラーク厚の臨床医による評価を表し(0〜5の等級)、
Sはプラークの剥離(scaling)の臨床医による評価を表す(0〜5の等級)。
6週間の試験において:
試験用ゲルで処置したプラークに対する患者1の乾癬症状の重症度スコアは100%から49%に低下したのに対し、対照で処置した部位では最初の値の96%に低下した。
