July World Medical Journal Review(医学雑誌レビュー)

Prof. Richard F. Lockey, MD, WAO Web Editor-in-Chief, reviewed premier July medical journal articles for practicing allergists. 南フロリダ大学Richard F. Lockey助教授による7月の医学雑誌に掲載されたアレルギー関連の文献紹介です。

1. EFFECTS OF EARLY INTERVENTION WITH INHALED BUDESONIDE ON LUNG FUNCTION IN NEWLY DIAGNOSED ASTHMA
This randomized, double-blind study of 7,165 patients (5 to 66 yrs) with persistent asthma for < 2 years determined whether early intervention with low-dose inhaled budesonide (IB) prevents severe asthma-related events and decline in lung function. Patients received IB (200 µg qd for children < 11 years and 400 µg qd for others) or placebo for three years in addition to the usual asthma medications. IB treatment significantly improved pre- and post-bronchodilator FEV1 percentage of predicted and reduced the mean declines from baseline for bronchodilator FEV1 at one and three years: -0.62% and -1.79% for IB and -2.11% and -2.68% for placebo, respectively (p<0.001). The decline was more marked for males, active smokers, and subjects > 18 years. The smallest treatment effects occurred in adolescents. Editor's comment: This multinational study demonstrates that low-dose IB improves lung function in recent-onset persistent asthma and reduces the loss of lung function over time. O'Byrne PM, et al. Chest 2006; 129: 1478.

新規に診断された喘息患者に対する吸入性ステロイド(ブデソニド)の早期介入効果について述べられている。この臨床治験は7000名以上の5歳から66歳までの喘息患者を対象として、ランダム化されたプラセボとの二重盲検法にて実施された。ブデソニド投与群ではプラセボに比し、気管支拡張薬を吸入する前の呼吸機能(FEV1値)のみならず、吸入した後のFEV1値までもが有意に改善した。最も効果が少なかったのは思春期の患者であった。訳者注:乳幼児期に対する吸入ステロイド薬の早期介入効果は、気管支拡張薬吸入後のFEV1値を改善しないことが報告されているが、6歳以降に発症する喘息患者に対しては有効であったことが示されている。

2. SENSITIZATION TO AEROALLERGENS AND AIRWAY HYPERRESPONSIVENESS (AHR) AT 7 YEARS OF AGE
One hundred thirty-one children at high risk for atopy underwent both skin-prick tests (SPT) to a panel of aeroallergens and a methacholine challenge test between 6.5 and 8.8 years (median-age 7.0 yr) of age to investigate the relationship between current and early life factors and AHR. Fifty-one percent (67) had at least one positive SPT and 28% (37) had AHR. After adjusting for relevant covariates, AHR was strongly associated with sensitization to at least four aeroallergens: cat, dust mite, cockroach, and ragweed. No relationship was found with early life exposure to perennial aeroallergens or other perinatal and first-year-of-life factors (daycare attendance, breastfeeding, tobacco exposure, and lower respiratory tract infection). The authors conclude that among young children at risk for atopy, sensitization to specific aeroallergens, but not early life exposures, is associated with increased AHR. Editor's comment: The major risk factor for AHR in this study was sensitization to cat, dust mite, cockroach, and ragweed. TePas EC, et al. Chest 2006; 129: 1500.

高リスクのアレルギー家族歴を有する7歳児131名について、吸入性アレルゲンなどに対する皮膚テストや気道過敏性(メタコリン負荷試験)を実施し、後方視的に周産期以後の環境についてアンケート調査を行った。その結果、これらの児のうち51%ではダニ、ネコ、ゴキブリ、ブタクサのうち少なくとも一つ皮膚テスト陽性であり、28%で気道過敏性が亢進していた。この結果は周産期や乳幼児期初期のダニ除去を目的とした環境整備、間接喫煙、呼吸器感染症の有無と相関しなかった。著者らは吸入性アレルゲンに対するアレルギーの獲得は乳児期の曝露とは関連せず、気道過敏性と相関していると結論している。

3. EARLY RISE IN EXHALED NITRIC OXIDE AND MAST CELL ACTIVATION IN REPEATED LOW-DOSE ALLERGEN CHALLENGE
Eight subjects with mild allergic asthma completed two 7-day repeated low-dose challenge periods with diluent and allergen, respectively. Subjects were symptom free at inclusion and were investigated when not exposed to specific allergen. Pulmonary function and symptoms were followed, and nitric oxide fraction (Fe,NO) and urinary mediators were correlated to changes in airway responsiveness to histamine and adenosine. There were no pulmonary function changes or asthma symptoms. Repeated allergen exposure, in contrast to diluent, caused significant increases in histamine responsiveness (2.3 doubling doses), an early and gradual increase in Fe,NO (up to a doubling from baseline) and a small increase in the mast cell marker 9α11β-prostaglandin F2 after adenosine challenge. Editor's comment: Serial low-dose allergen exposure causes airway inflammation. Ihre E, et al. Eur Respir J 2006; 27: 1152.

喘息患者は家庭において低容量の持続的なアレルゲン負荷を受けているはずであり、病院などで行うアレルゲン負荷とは異なる病態が予測される。著者らは8名の喘息患者に対し、希釈したアレルゲンを7日間繰り返し負荷し、呼気中の種々のメディエーター測定を行った。その結果、呼気中のNO酸化窒素濃度が有意に増加、ヒスタミン負荷試験に対する過敏性が増加した。また、マスト細胞活性化の特異的マーカーである9α11β-prostaglandin F2が少し増加した。以上のことより、少量持続アレルゲン負荷試験により発作は誘発されないものの、マスト細胞の活性化に引き続く気道炎症がおきていること、気道過敏性が亢進することが判明した。

4. RAPID SUBCUTANEOUS IgG REPLACEMENT THERAPY IS EFFECTIVE AND SAFE IN CHILDREN AND ADULTS WITH PRIMARY IMMUNODEFICIENCIES – A PROSPECTIVE, MULTI-NATIONAL STUDY
Sixty patients (16 children, 44 adults) participated in this study to evaluate: (1) IgG levels when switching patients from intravenous IgG (IVIG) infusions in hospital to subcutaneous (SCIG) self-infusions at home using the same cumulative dose, (2) protections against infections, and (3) safety of a new, ready-to-use 16% IgG preparation. Ten adults who had been on SCIG therapy for years served as controls. In total, 2,297 infusions were given and 28 (1%) had systemic adverse reactions, none severe. SCIG administration was safe and high IgG levels were easily maintained resulting in protection against infections. Editor's comment: SCIG is safe and effective and could be more cost effective than IVIG. Gardulf A, et al. J Clin Immunol 2006; 26: 177.

原発性免疫不全症に対しては通常免疫グロブリンの静脈内投与が行われる。著者らは、将来的な患者による自己注射実施を目指して免疫グロブリンの皮下投与試験を行い、それが有効かつ安全であったことを報告している。

5. PROGNOSTIC FACTORS OF ASTHMA SEVERITY: A 9-YEAR INTERNATIONAL PROSPECTIVE COHORT STUDY
The Global Initiative for Asthma categorization was used in 2002 to investigate severity of asthma in 856 subjects identified with asthma from 1991-93 in the European Community Respiratory Health Survey. The severity (remittent, intermittent, mild, moderate, severe), as measured at baseline, was a determinant of a patient's severity at follow-up. Moderate and severe persistent asthma are characterized by early deterioration of lung function. High IgE levels and persistent cough/mucus hypersecretion are strong markers of moderate/severe asthma. Remission occurs primarily in individuals with less severe asthma. Editor's comment: Severe asthma begets severe asthma. de Marco R, et al. J Allergy Clin Immunol 2006; 117: 1249.

ヨーロッパ呼吸器学会による喘息重症化の予測因子の検討が9年間の前方視コホート試験にて行われた。その結果、高IgE抗体や持続した咳嗽の存在がその後の喘息重症化と関連していた。

6. FUNCTIONAL POLYMORPHISMS IN THE MANNAN-BINDING LECTIN (MBL) 2 GENE: EFFECT ON MBL LEVELS AND OTITIS MEDIA
Twelve genetic variants in the MBL2 gene and functional MBL serum levels were determined in a cohort of children with recurrent acute otitis media. Haplotypes were constructed and associated with functional MBL serum levels and the number of otitis episodes in the previous year. Single nucleotide polymorphisms in the promoter region, in exon 1, and in exon 4 of MBL2 were found to contribute to increased risk for otitis media in children younger than two years of age . Editor's comment: MBL is clinically important during early childhood when maternally derived antibodies and protective adaptive immunity is not fully developed. Wiertsema SP, et al. J Allergy Clin Immunol 2006; 117: 1344.

2歳以下の中耳炎の罹患がマンノース結合レクチン(MBL)2遺伝子の多型と関連していることがわかった。実際、MBLは経胎盤的なIgGの輸送に関連している。

7. CHEMOKINES INDICATE ALLERGIC BRONCHOPULMONARY ASPERGILLOSIS (ABPA) IN PATIENTS WITH CYSTIC FIBROSIS
Levels of the Th2 chemokines thymus- and activation-regulated chemokine (TARC) and macrophage-derived chemokine (MDC) were measured in patients with CF and ABPA, asthma and ABPA, CF colonized with Aspergillus fumigatus, CF sensitized to A. fumigatus, atopic patients with CF, and non-CF atopic control subjects. Serum levels of TARC differentiate patients with CF or patients with asthma with ABPA with all others. Longitudinally, levels of TARC indicate ABPA exacerbations, suggesting TARC as a marker for identification and monitoring of ABPA in patients with CF. TARC vs IgE is a more sensitive marker for exacerbations for patients with CF and ABPA. Editor's comment: Perhaps TARC is a therapeutic target in patients with ABPA. Hartl D, et al. Am J Respir Crit Care Med 2006; 173; 1370.

嚢胞性肺線維症の患者はしばしばアレルギー性気管支肺アスペルギルス症(ABPA)を合併するが、Th2細胞の遊走に関連するTh2ケモカインのTARCを測定すると、TARCが高値を示す患者において、ABPAの合併率が高いことが判明した。

8. MAJOR CONGENITAL MALFORMATIONS AFTER FIRST-TRIMESTER EXPOSURE TO ACE INHIBITORS
A cohort of 29,507 infants was studied between 1985 and 2000. Two hundred nine and 202 were exposed to ACE inhibitors and other antihypertensive medications, respectively, during the first trimester and compared to 29,096 controls. Infants with only first trimester exposure to ACE inhibitors, had an increased risk of major congenital malformations (risk ratio (RR), 2.71; 95% confidence interval (CI), 1.72 to 4.27), particularly of the cardiovascular and central nervous systems (RR, 3.72; 95% CI, 1.89 to 7.30). ACE inhibitors should be avoided during pregnancy. Editor's comment: All physicians should be aware that ACE inhibitors used during pregnancy are associated with congenital malformations. Cooper WO, et al. N Engl J Med 2006; 354: 2443.

9. RHINITIS MEDICAMENTOSA (RM)
RM is a condition induced by the overuse of nasal decongestants. The term RM, also called rebound or chemical rhinitis, is also used to describe the adverse nasal congestion that develops after using medications other than topical decongestants. Such medications include oral ß-adrenoceptor antagonists, antipsychotics, oral contraceptives, and antihypertensives. There are different mechanisms through which congestion is caused by topical nasal decongestants vs. oral medications. This article reviews rhinitis medicamentosa as well as drug induced rhinitis. It reviews its presentation, physiology of nasal congestion, mechanisms of action of nasal decongestants, pathophysiology of RM, histology of RM, treatment of RM, and the need for further research. Editor's comment: RM and drug induced rhinitis have to be first recognized before they can be treated. Ramey JT, et al. J Investig Allergol Clin Immunol 2006; 16: 148.

10. LOW-DOSE INHALED AND NASAL CORTICOSTEROID USE AND THE RISK OF CATARACTS
A matched nested case-control analysis was performed in a population-based cohort of elderly people who had been dispensed medications for airway disease through a universal drug benefit plan. Inhaled (lung) corticosteroid (IGC) use was associated with a dose-related increase in both the risk of all cataracts and severe cataracts requiring extraction, and the increase in risk of severe cataracts was apparent even at daily doses of < 500 µg. The authors conclude that among the elderly, even low-doses of IGC are associated with a small but significant excess risk of cataracts requiring extraction. This excess risk was not observed with nasal corticosteroids (NGC). Editor's comment: ICG and NGC should be used in the lowest possible doses to maintain disease control. Ernst P, et al. Eur Respir J 2006; 27: 1168.

WAO Member Society Spotlight - The Allergy and Immunology Society of Thailand

Dear Colleagues,

Asia is the largest continent in the world. Its population is almost ten-fold that of the United States. Consequently, patients suffering from allergic and immunologic diseases in Asia are a large pool of underserved population due to limited human resources and infrastructures. Within the last decade, several advances in allergy research and development have been made in Asia, beginning in Japan and Korea. In 1991, the Asia-Pacific Association of Allergy and Clinical Immunology was founded, and its first congress was launched in Bangkok, Thailand. In 1997, the Asia-Pacific Association of Pediatric Allergy, Respirology and Immunology took shape and has served as a hub for communication between key researchers and pediatric allergists in Asia. These developments have led to a quick leap in research and insights into allergy in Asia, both in research and in clinical care.

During December 2-6, 2007, in Bangkok, Thailand, Asia will have a chance to host a world-premier event in Allergy – the XX World Allergy Congress (WAC 2007), the biannual meeting of the World Allergy Organization (WAO). As a prelude to this forthcoming meeting, the Allergy and Immunology Society of Thailand (AIST) is planning a warm-up event for the WAC 2007. The Allergy and Immunology Network in Asia, Quantum Leap to the Future Summit Meeting will be held in Pattaya, a famous seaside resort of Thailand, October 5-6, 2006. The meeting will feature several keynote speakers from Japan, Hong Kong, Indonesia, France, Italy and the United States. Topics covered will be broad, including basic and every-day clinical research.

Since Thailand is within easy reach for most Asian countries, traveling to our Congress will be quick and affordable to most members of national allergy societies in Asia. The cost for joining the Congress is kept to a minimum to allow participation even from newly-developing countries in Asia. Moreover, ample time will be allowed to acquaint new comers to old guards in allergy and immunology. We cordially invite you to enjoy the Summit and look forward to seeing you in Pattaya in October 2006.

Pakit Vichyanond
President
Allergy and Immunology Society of Thailand

Allergy Book Review

STRUCTURAL BIOLOGY of the COMPLEMENT SYSTEM
Morikis D, Lambris JD, eds.
2005 CRC Press

今月のアレルギー書籍の紹介は補体システムの構造生物学である。研究者向きであるが、補体に関する進歩が理解できる。

List price: $169.95
Available from:
CRC Press

Reviewer:
Dr Olga Patricia MARTINEZ, MB BS, FRACP, FRCPA, PhD
Royal Perth Hospital, PathWest, School of Surgery and Pathology, University of Western Australia

Description:
The discovery of the complement proteins and molecules involved in their activation and inhibition has taken many years. This book describes the current knowledge of the structure of complement components and of complement activator and inhibitory molecules. Each chapter is dedicated to particular components, with a detailed description of their structure and function and how these correlate with each other. The final two chapters describe molecules that control complement activation, for which analogues could potentially be designed and produced for therapeutic purposes.

Purpose:
The purpose of this book was to assemble a volume containing the current state-of-the-art of the structural biology of components, activators and inhibitors of the complement system, with structure-function correlations.

Audience:
This book is predominantly targeted to researchers interested in understanding the many molecules participating in complement-mediated responses, including activating and inhibiting molecules and their interactions. It is also directed to researchers interested in protein dynamics and thermodynamics of these processes. Some sections of the book that describe the role of the complement system in innate and acquired immunity would be of interest to immunologists. The potential for synthetic molecules to control complement activation is of interest to clinicians dealing with immune-mediated disorders.

Features:
The first chapter provides a historical overview of discovery, purification and description of three-dimensional structure of complement proteins. Subsequent chapters describe in detail the molecular and modular structure of complement control proteins (CCP), individual complement proteins, some complement receptors and activators and inhibitors. Each chapter is well ordered with a table of contents and contains clear tables and diagrams. Each chapter concludes with an extensive list of references and, where required, acknowledgment of funding and contribution by colleagues.

A companion CD is provided with the book. This contains all figures and legends in separate Acrobat files. Most figures are in black and white, but some have color to highlight specific features. There are links to the PDB (Protein Data BanK) for all structures discussed and for complement-related proteins and viral, semi-synthetic or synthetic complement regulators or inhibitors reviewed. The CD also contains the "RasTop" bio-molecular structure visualization program, which reads and displays PDB coordinate files.

Assessment:
The existence of the complement system has been recognized for many years. However, detailed description of the structure of its many components has taken many years and many techniques. This book brings together much of the currently available knowledge in this area. While there are still many unanswered questions about the precise mechanism of action and the many interactions involved in complement-mediated reactions, the potential for new therapeutic interventions makes it an exciting area for further investigation. The detailed information provided in STRUCTURAL BIOLOGY of the COMPLEMENT SYSTEM would be extremely useful for future researchers in this area, making this book a must-have for those intending to pursue this interesting field of research.
