    After informed consent, subjects will be randomly assigned to ILIT group or placebo group in double-blind manner.

    In both group, causal allergen or placebo will be injected into inguinal lymph node through guidance by ultrasonography three times with 4-week interval. In ILIT group, initial dose of allergen will be 1,000-fold diluted solution from maximal concentration of allergen extract for subcutaneous immunotherapy (Tyrosine S, Allergy Therapeutic, West Sussex, UK) in volume of 0.1ml. If skin is highly reactive in skin prick test, the initial dose will be 10-fold dilution from maximal concentration where diameter of wheal is less than that of histamine.

    After the first dose, allergen concentration will be escalated 3-fold at second dose, and 10-fold at third dose if there are no (or mild) local or systemic hypersensitivity reaction. The allergen concentration will not change at second or third dose if there is moderate local or systemic reaction. The allergen concentration will decrease by 10 or 100-fold from previous concentration or further injection will be held if there is severe local or systemic reaction after sufficient explanation and discussion with subjects.

    The investigators will assess allergic rhinitis symptom score before and 4, 12 months after the initial treatment.

    Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) and Sino-Nasal Outcome Test (SNOT-20) will be used. Visual analogue scale (VAS) of symptoms including rhinorrhea, sneezing, nasal obstruction, postnasal drip, eye/nose/ear/palate itching, dyspnea, wheezing, chest discomfort as well as urticaria, angioedema, and itching on exposed skin during exposure to causal allergen in daily life will be also evaluated. Skin prick test (SPT), intradermal test (IDT), blood sampling for serum entire immunoglobulin E (IgE), allergen-specific IgE, and allergen-specific immunoglobulin G4 (IgG4), nasal lavage for Th1, Th2, and Treg cytokines, and nasal provocation test (NPT) with Df and/or Dp allergen (in subjects whose AR symptoms are provoked by Df and/or Dp) will be also performed before and 4, 12 months after the initial treatment.

    In addition, the investigators evaluated the change of subjects’ recognition of causal allergens, their avoidance, and AIT during this study. Using VAS, subjects were requested to score the rate of agreement with "Allergen provokes allergic symptoms in daily life", "Allergen avoidance can reduce allergic symptoms", "Allergen-specific Immunotherapy (AIT) can reduce allergic symptoms", "I can pay 50,000 Korean Won (KRW)/month for allergen avoidance", "I can pay 100,000 KRW/month for allergen avoidance", "I can pay 200,000 KRW/month for allergen avoidance", "I can pay 150,000 KRW for each injection of ILIT", "I can pay 300,000 KRW for each injection of ILIT", "I can pay 600,000 KRW for each injection of ILIT" before and after SPT/IDT, after NPT, 4 months and 1 year after ILIT.

    Adverse events will be recorded and graded according to Muller classification and Ring and Meissner classification.

    This article was first published in the Bulletin of the World Health Organization,
    72(5):796-806 (1994), and is reproduced here by permission.

    A. Introduction.

    Rapid advances own been made in the past few years on allergen characterizationand sequence determination by chemical and molecular biological approaches.

    This is indicated by the list of allergens with known partial or finish amino acid sequences in Table 1.

    A number of other significant allergens are known in addition to those in Table 1 but their sequences are as yet not known. A useful source for known allergens is the Allergen Database (ALBE) in which are compiled their known biochemical and immunological properties together with their
    sequence data if known (1).

    To take into account these advances, a revision of the current allergen
    nomenclature system (2) is given under. As in the current nomenclature system,
    the proposed revisions are for allergens which induce IgE-mediated (atopic) allergy in humans. In addition to the expected thorough immunochemical characterization of any newly discovered allergen, investigators are urged to obtain partial, or preferably finish, sequence data before using the official nomenclature system.

    Also it is expected that investigators would screen a reasonable population size so as to establish the frequency of response in patients to the newly discovered allergens. (Investigators are invited to consult our committee members for assigning an allergen number before publication so as to avoid duplication).
    Investigators frequently refer to allergens as major or minor ones. The
    generally accepted meaning of this terminology is that an allergen is designated as either major or minor depending on whether greater or less than 50% of  patients tested own the corresponding allergen-specific IgEs (cf.

    The revised nomenclature for allergens is given under together with the
    proposed nomenclatures for (a) allergen genes, mRNAs and cDNAs and (b) recombinant and synthetic peptides of allergenic interest.

    B. Revised Allergen Nomenclature.

    1. Allergens.

    Allergens are designated according to the accepted taxonomic name of their source as follows: the first three letters of the genus, space, the first letter  of the species, space, and an Arabic number.

    The numbers are assigned to the allergens in the order of their identification, and the same number is generally used to designate homologous allergens of related species. As two examples, Lol p 1 refers to the first pollen allergen identified from Lolium perenne, rye grass, and Cyn d 1 refers to the homologous pollen allergen from Cynodon dactylon, Bermuda grass.
    In some instances, the above system of the first 3 letters of a genus and the first letter of a species has to be modified to include an additional letter for designation of the exact genus or species.

    For example, 4 of the numerous vespids which can cause insect allergy are Vespula vulgaris, Vespula vidua, Vespula consobrina and Vespa crabo. The homologous major venom allergens, antigen 5s, from Vespula vulgaris and Vespula vidua are both designated as Ves v 5 in the existing nomenclature, and those from Vespula consobrina and Vespa crabo are designated as Ves c 5. To avoid these ambiguities, antigen 5s from Vespula vulgaris and Vespula vidua will be designated as Ves v 5 and Ves vi 5 respectively, and those from Vespula consobrina and Vespa crabo as Ves c 5 and Vesp c 5. In the examples given, the modified nomenclature is used for the allergens from Vespula vidua and Vespa crabo, as the allergens from Vespula vulgaris were characterized prior to those for Vespula vidua and Vespa crabo.

    Another example is for allergens from the domestic dog (Canis domesticus) and the mold Candida albicans. To avoid ambiguity, the modified system is used to designate Can d and Cand a allergens from these two sources respectively.
    In the current nomenclature system (2) the letters are italicized and the numerals are Roman numerals. In the revised system, only letters of normal type and Arabic numbers are used. The proposed changes conform to the accepted nomenclature used in bacterial genetics (6) and HLA system (7) in that italicized and normal characters are used to represent genotypes and phenotypes respectively. Allergens are designated according


    Allergens and isoallergens.

    An allergen from a single species may consist of several closely similar
    molecules. These similar molecules are designated as isoallergens when they share the following common biochemical properties:
      a. similar molecular size
      b. identical biological function, if known, e.g. enzymatic action
      c. > 67% identity of amino acid sequences.

    It is recognized that the recommended > 67% sequence identity for 2 allergens to be assigned to the same group is only a guide.

    There are likely to be borderline cases. As an example, the ragweed allergens Amb a 1 and 2 share 65% amino acid sequence identity (8). These allergens were assigned to diverse groups because of their diverse immunochemical properties before their sequences were known.
    Allergens from diverse species of the same or diverse genus which share the above-mentioned common biochemical properties are considered to belong to the same group and the sequence identity requirement can be < 67% as is the case for allergens of the same species. For example, Amb a 5 and Amb t 5 from short and giant ragweed pollens own about 45% sequence identity (9), and also own similar tertiary structures (10, 11).

    Another example is the minor pollen allergens Amb a 10, Poa p 10 and Lol p 10 from ragweed (12), Kentucky bluegrass (13) and rye grass (14).
    Although their sequences are not known, they are assigned to the same allergen group as they clearly own the same biological function of cytochrome c.

    3. Isoallergens and variants.

    cDNA cloning of allergens often show nucleotide mutations which are either silent or which can lead to single or multiple amino acid substitutions. In the revised system, members of an allergen group which own > 67% amino acid sequence identity are designated as isoallergens.

    Each isoallergen may own multiple forms of closely similar sequences, which are designated as variants.
    Isoallergens and their variants belonging to the same allergen group are designated by suffixes of a period followed by four Arabic numerals. The first two numerals 01 to 99 refer to a specific isoallergen, and the two subsequent numerals 01 to 99 refer to a specific variant of a specific isoallergen designated by the preceding two numerals. In cases where there is only one known isoallergen but there are several variants, the system of a suffix of 4 numerals will still apply. These numerals will be chosen in the order of the identification of allergens and/or their cDNAs irrespective of the physicochemical properties of the allergens.

    In cases of silent mutations, there can be more than one suffix of 4 numerals designating the same allergen and in that case the suffix with the lowest number will be used to designate the allergen of interest.
    The addition of suffixes of 4 numerals to designate isoallergens and their variants will permit their unambiguous designation. In numerous cases it is unnecessary to specify the isoallergen or variant and the corresponding suffixes may be deleted; e.g. Bet v 1 represents any Bet v 1 allergen and Bet v 1.0101 represents variant number 1 of isoallergen Bet v 1.

    Two other examples of this nomenclature system are given under.
    On cDNA cloning, Amb a I showed multiple polymorphic forms which differ from each other by 12-24% in their sequences (8). Four such forms of Amb a I are known and they are designated as Amb a 1.01, 1.02, 1.03 and 1.04. Each isoallergen of the Amb a I group is found to own 1 to 3 variants with > 97% of&n sequence identity. These variants of the Amb a 1.01 group will be designated as Amb a 1.0101, 1.0102 and etc.

    In contrast to Amb a I, only two forms of Amb a II were found on cDNA cloning. These forms differ in two polymorphic sites and they own > 99% amino acid sequence identity. They are designated as Amb a 2.0101 and 2.0102.

    C. Nomenclature for allergen genes, mRNAs and cDNAs.

    At present the genomic structures of allergens are known in at least two cases; cat allergen Fel d 1 and mouse urinary allergen Mus m 1. Knowledge of the genomic structure can provide an understanding of how the diverse polymorphic forms are generated by differential splicing and/or exon usage.

    By adopting the revised nomenclature for allergens, we can reserve the italicized characters to designate an allergen gene. Normal characters are used for designation of mRNAs and cDNAs.
    For example, Fel d 1 is a protein consisting of two polypeptide chains (15) which are encoded by two separate genes (16). The two allergen genes for chains 1 and 2 of Fel d 1 will be represented by Fel d 1A and Fel d 1B respectively.
    Allelic forms of mRNAs and cDNAs of the Fel d 1A gene are designated as mRNA or cDNA Fel d 1A.0101 where the numerals are to correspond to those of the polymorphic allergens.

    D. Nomenclature for recombinant and synthetic peptides of allergenic interest.

    There is interest in the possible use of fragments of allergens as reagents to modulate allergen-specific immune responses. Such fragments may be prepared by recombinant technology or by chemical synthesis. Therefore it is useful to establish a generally accepted nomenclature for such peptides of allergenic interest.
    The nomenclature for recombinant and synthetic peptides of allergenic interest is to be based on the nomenclature for naturally occurring allergens since it is well accepted by the scientific and the clinical communities.
    An allergen which is prepared by recombinant (r) or chemical synthetic (s) means is to be differentiated from a natural (n) allergen by the addition of the prefix of r or s followed by a suffix of the amino acid residue positions which are given in parenthesis.

    For examples, a recombinant hornet venom allergen Dol m 5.0201 which contains the entire sequence of 204 residues will be designated as rDol m 5.0201, and a recombinant or synthetic peptide of residue 151-165 of Dol m 5.0201 will be designated as r or sDol m 5.0201 (151-165) respectively.
    Natural allergens may contain post-translational modifications as numerous proteins do. These modifications include glycosylation, acylation, methylation and etc. Recombinant or synthetic allergen, designated by the prefix r or s, is taken to indicate that it does not contain the post-translational modification of the natural allergen.

    If the recombinant or synthetic allergen does contain the exact same modification as that of the natural allergen, it will be designated with a prefix of rn or sn. For example, the honey bee venom allergen phospholipase A2, Api m 1, is a glycoprotein with an oligosaccharide attached at the asparagine residue number 13 (17, 18). A synthetic peptide of residues 1-20 of Api m 1 without the oligosaccharide at residue 13 will be designated as sApi m 1 (1-20), and a synthetic peptide of residue 1-20 with the exact same oligosaccharide of the natural allergen will be designated as snApi m 1 (1-20).
    For recombinant or synthetic fragments which are derivatives of sequences contained within the native allergen structure, an additional suffix enclosed in square brackets will be used to indicate that the peptide referred to is an analogue.

    Substitutions or modifications of amino acid residues are given with the standard one-letter code and superscript numbers indicate the residue positions at which modifications happen. The one-letter codes for L-amino acids are given in upper case letters and those for D-amino acids are in lower case letters.
    The modifications which can be substitution, insertion or deletion are specified in parenthesis within the brackets. Obviously when there are numerous changes, it will not be practical to follow this nomenclature but to give the fully modified sequences. Examples of these analogs of sDol m 5.0201 (151-165) are given below:

    1. Unmodified: sDol m 5.0201 (151-165)
    2. Insertion: sDol m 5.0201 (151-165) [+K 153] — one residue of L-lysine is inserted between positions 153-154
    3. N-terminal modification: sDol m 5.0201 (151-165) [N-Ac] — N-terminal amino group is acetylated
    4. Deletion: sDol m 5.0201 (151-165) [-K 153] — L-lysine residue at position 153 is deleted
    5. Substitution: sDol m 5.0201 (151-165) [k 153] — L-lysine residue at position 153 of sDol m 5.0201 (151-165) is substituted with D-lysine
    6. C-terminal modification: sDol m 5.0201 (151-165) [C-NH2] — C-terminal carboxyl group is in the form of carboxamide

    The nomenclature proposed above is extremely similar to that used for synthetic pe ptides representative of immunoglobulin sequences (19).

    References refer to those where partial (P) or finish (C) sequence data are available. The original references describing the initial characterization studies are not given because of limited space. Also we apologize to our colleagues whose allergen sequence data we may own overlooked, or whose publications appeared after Dec., 1993, for inclusion in this table.

    Sequence data for group 5 and 9 allergens from several grass pollens indicate that they are highly homologous proteins. Comparison of finish sequencedata of group 5 and 9 allergens from a single grass species will clarify whether these two groups are the same protein.

    Allergen extracts are currently manufactured in two forms: standardized and non-standardized. For the standardized allergen extracts, manufacturers compare the allergen extract to a U.S. reference standard for potency. CBER maintains these reference standards and distributes them to manufacturers. There are currently 19 standardized allergenic extracts.

    Extracts for which there are no U.S. reference standards are called non-standardized extracts.
