Abstract:
A method for determining the likelihood of response of an individual, suffering from a disease, towards immunoglobulin therapy has the steps of
       providing a sample containing B- and T-lymphocytes, natural killer cells, invariant T-cells and monocytes of the individual;   genotyping of at least one of the polynucleotides of an ADAMTS9-Intron; a KLHDC8A-Intron or of a flanking region of the CD14 gene, and   awarding the value of 1 for the homozygous Single Nucleotide Polymorphism combinations, which suggests that the blood sample stems from a person which will not respond to immunoglobulin treatment,   while awarding the value of 0 for SNP not meeting that criteria, which suggests that the blood sample stems from a person which will respond to immunoglobulin treatment.

Description:
[0001]    The invention pertains to a method of determining the individual responsiveness toward immunoglobulin therapy. 
         [0002]    B cells identify pathogens when antibodies on their surface (B-cell receptor) bind to a specific foreign antigen. In response, B cell divide and differentiate into plasma cells, which secrete millions of copies of the antibody that recognize the activating antigen. Antibodies (also known as immunoglobulins) recognise targets comprising many different compounds, structures and those also as part of cellular structures and often neutralise their biological effect. The immune complexes are cleared fast leading to the elimination of a “target” molecule, accordingly, recognition, binding and removal function is doubtless of essential importance, which is substantiated by the fact that patients lacking (or have reduced) immunoglobulin levels are prone to serious and recurrent infections. Beyond this protection function towards intruders, immunoglobulins bear important regulatory function in balancing and regulating the immune system. Immunoglobulin products, usually derived from pooled blood or plasma donations and prepared according processes well known to the expert, are used for the treatment of IMID (immune mediated inflammatory diseases) and so called AID (autoimmune diseases), while those definitions may express identical or overlapping features of a disease. The immunoglobulin G (IgG) concentrates are usually applied intravenously (IVIG) or subcutaneously (SCIG), but may be also intramuscularly, inhaled, intra-ocularly, orally or topically. When B cells react aggressively against self, the potential for pathology is extreme. It is therefore not surprising that B-cell depletion is seen as an attractive therapy in patients with autoimmune diseases or immune mediated inflammatory diseases (IMIDs). 
         [0003]    Natural killer (NK) cells are large granular lymphocytes that belong to the innate immune system because unlike T- or B-lymphocytes of the adaptive or antigen-specific immune system, NK cells do not rearrange T-cell receptor or immunoglobulin genes from their germline configuration. NK cells have been characterized as a lymphocyte lineage with both cytotoxic and cytokine-producing effector functions. NK cells accomplish selective lysis of cells on the basis of activating and inhibitory receptors relatively specific to the NK cell lineage. Activating receptors such as NKG2D recognize natural stress signal ligands or pathogen-derived ligands expressed on transformed or infected cells. In contrast, the inhibitory receptors of the CD94-NKG2A complex, KIR family (Killer-cell Immunoblobulin-like Receptors) bind self but not allogeneic MHC I (Major Histocompatibility Complex I). The KIR receptors are highly polymorphic, heterogeneously expressed among NK cells, and important in NK cell self-tolerance. During licensing, NK cells acquire functional competence following productive interactions between inhibitory receptors and self-MHC during development. Licensed NK cells express at least one of several possible inhibitory receptor alleles. Hence, MHC-recognition among NK cells is diverse so that at least one NK cell subset will respond to downregulation of any single MHC class I molecule. When activating NK cell effector functions are primed, IFN-γ is secreted and granzyme and perforin release are enhanced. NK cells also express Fcγ receptors, which recognize several IgG subclasses, to mediate antibody-dependent cellular cytotoxicity. These receptors and their roles in NK cell surveillance and cytolysis have been well studied and are closely associated with the identity of NK cells. Upon flow cytometry so called CD56 bright  and CD56 dim  can be differentiated which do or do not express Fcγ RIII (CD16). The interpretation of the flow cytometry results upon ‘gatings’ is well known to the skilled person. 
         [0004]    Accordingly, 4 major sub-populations can be defined, which are 
       CD16+/CD56 bright    
     CD16+/CD56 dim    
     CD16−/CD56 bright    
     CD16−/CD56 dim    
       [0005]    NK cells are an important part of the host defence. However, if dysregulated, e.g. as reason or in the course of diseases, they can direct themselves against “self-structures” with significant pathophysiological consequences, like attack of organ structures and oligodendrocytes in the periphery and brain. Although the mechanisms are not fully understood leading to such self-attacks, regaining control of these cells and reducing their killing power to a physiologically reasonable level is required. As killing efficiency is tightly connected to degranulation and release of effector molecules, it is an aim to control such degranulation to reduce damage. 
         [0006]    The effectivity of intravenous immunoglobulin (IVIG) in autoimmune diseases was first described in the 1950ies and then in the 1980ies, when it was used to treat patients suffering from idiopathic thrombocytopenic purpura. In the mean-time many clinical studies demonstrated a beneficial effect of IVIG in autoimmune diseases. Among others, IVIG therapy is proven in Guillain-Barre syndrome (GBS), Kawasaki syndrome, chronic inflammatory demyelinising polyneuropathy, myasthenia gravis and corticosteroid-resistant dermatomyositis (Ephrem et al., 2005; Kazatchkine and Kaveri, 2001; Boros et al., 2005). A positive effect of IVIG on disease progression relapse rate and MRI enhancing lesions in multiple sclerosis (MS) was demonstrated by clinical studies as well (Sorensen PS, 2003; Sorensen et al., 2002). An established method to assess the status of disease is the EDSS Expanded Disability Status Scale (EDSS). 
         [0007]    The complete mechanism of action of IVIG is still unclear but seems to involve the modulation of expression and function Fcγ receptors, interference with complement activation, modulation of T- and B-cell activation, -differentiator and -effector functions (Ephrem et al., 2005; Kazatchkine and Kaveri, 2001; Boros et al., 2005). 
         [0008]    While immunoglobulin prophylaxis and treatment is successfully used in many patients, among them are cases who poorly or even not respond to immunoglobin application. Recent approaches suggest to qualitatively or quantitatively determine distinct blood cell or cell-derived factors, alone or in combination, to facilitate a individualized predictive parameter of responsiveness towards immunoglobin therapy. 
         [0009]    Asphalter et al in Clin Exp Immunol 2000, 121, 506-514 reported effects of in vivo IVIG replacement therapy and high-dose IVIG (2 g/kg body weight) on NK cell subsets. They describe an assay wherein intracellular IFN-γ was measured in NK cells before and after IVIG therapy (200-400 mg/kg every 3 weeks). Ruiz. et al. in Journal of Reproductive Immunology, 31 (1996), 125-141 pertains to the immunological mechanism of IVIG to inhibit NK activity in vitro when it was added to NK cytotoxicity assays using peripheral blood lymphocytes as targets. However, in both reports these findings were not related to efficacy of IVIG therapy in individual patients 
         [0010]    Tha-In Thanyalak et al. in BLOOD, Vol 110, No 9, 9. November 2007 report the effects of dendritic cells (DC&#39;s) matured for 18 hours in the presence of IVIG on natural killer (NK) cells. The effect of these cells on NK cell phenotype was examined by measuring the expression of Fc-gamma RIII after 5 days. INF-γ production and degranulation of NK cells was also analysed in co-cultures with IVIG-DC&#39;s after 48 hours and revealed increased expression of interferon-gamma. However, NK cells treated with IVIG without DC&#39;s showed only marginal activation. Thus, Tha-In concluded that only IVIG-DC&#39;s activate NK cell degranulation properly. 
         [0011]    Kwak Joanne Y. H. et al. in EARLY PREGNANCY, Vol IV, pp 154-164 investigated the clinical effect of IVIG treatment in recurrent aborters with elevated NK cell levels while concomitantly receiving additional treatments. NK cytotoxicity and expression of CD16 was found to be significantly suppressed 5-7 days after IVIG infusion. There was no intention to use these findings to predict individual responsiveness toward IVIG therapy. 
         [0012]    EP-A-1 801 234 relates to a diagnostic method to predict whether a subject is predisposed for acquiring a disease or developing an autoimmune disease by use of recombinant nucleic acid constructs. Such constructs are not used by the present application. 
         [0013]    Park-Min Kyung-Hyun et al. in IMMUNITY, vol. 26, no. 1, January 2007, pp 67-78 describes several investigations related to the influence of IVIG on cellular responses to interferon-gamma. These investigations were mainly based on observations of  Wisteria monocytogenes  and on macrophages, which are not NK cells. 
         [0014]    Meuer et al. describe a method to predict individual responsiveness towards immunoglobulin therapy by focusing on NK cell-associated and -derived factors like cytokines and enzymes and degranulation related parameters (WO2009/087219). 
         [0015]    Beside several biochemical parameters, Meuer et al. reported that the amount of CD56-bright CD3-negative NK cells can decrease after immunoglobulin treatment in patients suffering from IMIDs. However, the predictive value for responsiveness towards immunoglobulin therapy has not been evaluated yet. The importance of B cells, functional immunologic and genetic factors was not addressed by this invention. 
       BRIEF DESCRIPTION OF THE INVENTION 
       [0016]    One object of the invention is to provide a reliable method to predict individual responsiveness towards immunoglobulin therapy, in particular to therapy with immunoglobulin G. 
         [0017]    Another object of the invention was to provide a method to predict individual responsiveness towards immunoglobulin therapy, in particular to therapy with immunoglobulin G which method is faster than known methods. 
         [0018]    The technical problem underlying the invention is solved by a method for determining the likelihood of response of an individual, suffering from a disease, towards immunoglobulin therapy comprising the steps of:
       providing a sample containing B- and T-lymphocytes, natural killer cells, invariant T-cells and monocytes of the individual;   genotyping of at least one of the polynucleotides of an ADAMTS9-Intron; a KLHDC8A-Intron or of a flanking region of the CD14 gene, and   awarding the value of 1 for the homozygous SNP (Single Nucleotide Polymorphism) combinations, which suggests that the blood sample stems from a person which will not respond to immunoglobulin (IG) treatment, while   awarding the value of 0 for SNP not meeting that criteria, which suggests that the blood sample stems from a person which will respond to immunoglobulin treatment.       
 
         [0023]    The present invention avoids the long-lasting assays as for example disclosed by Tha-In (48 hours and 5 days) performed with different cells compared to the present invention (IVIG-DC&#39;s are not used by the present invention). Furthermore Tha-In does not find an indication to use the findings for the determination of individual responsiveness towards IVIG therapy. In addition, the only comparable assay disclosed in Tha-In (NK cells treated with IVIG) showed contradictory results compared to the present invention, unfortunately, no specific conditions were published, which makes a substantial comparison impossible (page 3257, left column, lines 3-7). 
         [0024]    The term “genotyping” is used as the skilled person understands. In particular the term means the process of determining the genotype of an individual by examining the individual&#39;s DNA sequence by using biological assays. More accurately, genotyping is the use of DNA sequences to define biological populations, by use of molecular tools Current methods of genotyping include PCR, DNA sequencing, Allele specific oligonucleotide (ASO) probes, and hybridization to DNA microarrays or beads. It is understood that genotyping is performed with a sample of an individual, i.e. ex vivo. 
         [0025]    The homocygotes are designated in the description of the invention as AA or BB, whereas the heterocygotes are designated AB or BA. 
         [0026]    The terms “ADAMTS9-Intron”, the “KLHDC8A-Intron” and “a flanking region of the CD14 gene” mean specific polymorphisms in the mentioned genomic segments of an individual. 
         [0027]    “Linar Discriminant Analysis” (LDA) is a method in statistics, pattern recognition and machine learning to find a linear combination of features which characterize or separate two or more classes of objects or events. Software is commercially available under the trade name IBM® SPSS® Statistics.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0063]    The technical problem underlying the invention is solved by a method predicting individual responsiveness towards immunoglobulin therapy, wherein the homocygocity of certain regions of ADAMTS9-Intron (intron of A disintegrin and metalloproteinase with thrombospondin motifs 9; at Chr.3p14.1 and physical positions 64560013, 64595571, 64602006, 64605119, 64612402, 64614313, 64617371, 64620883, respectively in the same order dbSNP RS ID&#39;s rs9820942, rs6780659, rs6445415, rs11721258, rs11707584, rs7652817, rs13079218, rs9819183) and KLHDC8A-Intron (intron of kelch domain containing 8A; Chr. 1q32.1 and physical positions 205312280-205318524-205318854-205318983, respectively in the same order dbSNP RS ID&#39;s rs7549293, rs10751436, rs913723, rs913722SNP&#39;s) or CD14 flanking region (at Chr. 5q31.3 (SNP Chromosom 5, Cytoband q31.3, physical positions 140007011, 140011315, 140014909, 140015208, respectively in the same order dbSNP RS ID&#39;s rs778588, rs2563298, rs5744448, rs2569192)), are determined as well as the amount of cytokines released from or their expressed genes on cells is determined. The term cytokine is to be understood as including its subgroup chemokines. The cytokines, respectively their expressed genes, are selected from the group of Interferon-gamma (IFN-γ), Interleukin-8 (IL-8 or CXCL8), C—X-C motif chemokine 10 (CXCL10 or Interferon gamma-induced protein 10 kDa (IP-10)), chemokine C-C motif ligand 8 (CCL8), chemokine C-C motif ligand 20 (CCL20), Interleukin-10 (IL-10) and Stem cell factor (SCF) and are used for prediction of IgG responsiveness alone or in combination with others. Also of interest is the release and/or gen-expression of CD32b, CD16 (FcR-γ III), CD 19, CD20, CD56, IL-6R (Interleukin-6 receptor) and ICAM-1 (Inter Cellular Adhesion Molecule 1). 
         [0064]    Cited cellular-biochemical parameters were studied in whole blood and derived from plasma and or leukocytes of patients suffering from relapsing-remitting multiple sclerosis by analyzing and comparing blood samples, drawn before and after administration of immunoglobulin (regular administration of 0.4 g IVIG/kg bodyweight). The study initially incorporated 33 individuals of which 6 were later excluded due to displaying obvious inflammatory activity or dropout. Analytical results of remaining 27 patients, 15 were found to be responders and 12 non-responders according to study-design, were thus used for determination of relevant parameters. 
         [0065]    While each of cited parameter revealed a certain predictive value after ROC-analysis (Receiver Operating Characteristic) on its own it was found, that a combination of one or more parameters based on cytokine (IFN-γ, CXCL8, CXCL10, IL-10 and SCF) release and/or gen-expression and genotyping of ADAMTS9-Intron or based on release and/or gen-expression of CD16, CD32b, IL-6R and ICAM-1 and genotyping of KLHDC8A-Intron was much more predictive as a strong correlation exists between responders to immunoglobulin treatment and said parameters with respect to prevention of relapses or extension of remission. It is also possible to combine the results of one of the genotyping assays with one or two of the other genotyping assays in order to identify possible false positive/negative results or to confirm the assessment of responders/non-responders. The confirmation of a responder determined by KLHDC8A-Intron genotyping by genotyping of the ADAMTS9-Intron can be seen as a non-limiting example for such a combination. It may be useful to use the genotyping results of the introns KLHDC8A and CD14, or ADAMTS9 and CD14, or even KLHDC8A and ADAMTS9 and CD14. 
         [0066]    Furthermore, these parameters can further be combined with other parameters increasing the predictability of immunoglobulin therapy response, e.g. NK cell degranulation parameters (granzyme B, perforin, or CD107a) and functional NK cell killing activity or combinations thereof. All of these parameters (cytokine release, cytokine gen-expression, NK cell degranulation parameters and functional NK cell killing activity) are generated in short-time ex vivo cultures of whole blood samples or plasma exposed to immunoglobulin (with or without LPS (lipopolysaccharide) stimulation). 
       Reagents and Assays 
       [0067]    Reagents, assays and assessment of results are well known to persons skilled in the art. Many assays were described in detail by Jacobi et. al. in Clinical Immunology (2009) 133, 393-401. 
         [0068]    General preparation of whole blood cultures was performed by admixture of heparinized venous whole blood to the same volume of a stock solution containing 20 mg/ml IgG in culture medium (RPMI—1640, 10% FCS, L-glutamine, penicillin, streptomycin, 50 μM β-mercaptoethanol) with. This mixture was incubated at 37° C. for 3 h, when qRT-PCR, FACS and NK cell killing-assays were to be performed, and for 24 h, when ELISAs were to be performed. Such assays are called “IG induced” throughout this application. Some assays were performed with lipopoliysaccaride (LPS, purchased from Sigma, St. Luis, USA) at 100 ng/ml final concentration in the mixture of whole blood, IgG and culture medium for stimulation. Such assays are called “IG/LPS induced” throughout this application. The same assays were also performed with maltose 10 mg/ml final concentration instead of IgG for comparison with IgG incubated assays. The difference between IG or IG/LPS incubated minus maltose or maltose/LPS (control samples as IG is missing) incubated assay results are denominated “(netto)” throughout this application. 
         [0069]    Genotyping was performed with whole blood on the GeneChip® Human Mapping 6.0 Array from Affymetrix according to the protocol of the manufacturer. Homozygous SNP (Single Nucleotide Polymorphism) combinations at relevant positions were incorporated in data analysis with a value of 1 while SNP not meeting that criteria received the value 0. In particular, the homozygous sequence of AA-BB-BB-AA of the CD14 flanking region (CHR.5q31.3), which is represented by the homozygous SNP combination A(dbSNP RS ID rs778588—physical position 140007011)-C(dbSNP RS ID rs2563298—physical position 140011315)-C(dbSNP RS ID rs5744448—physical position 140014909)-C(dbSNP RS ID rs2569192—physical position 140015208) and the homozygous sequence of AA-BB-AA-BB of the KLHDC8A-Intron (Chr. 1q32.1), which is represented by the homozygous SNP combination C(dbSNP RS ID rs7549293—physical position 205312280)-T(dbSNP RS ID rs10751436—physical position 205318524)-A(dbSNP RS ID rs913723—physical position 205318854)-T(dbSNP RS ID rs913722—physical position 205318983), as well as the homozygous sequence of BB-AA-AA-BB-AA-BB-BB-AA of the ADAMTS9-Intron at Chr. 3p14.1, which is represented by the homozygous SNP combination G(dbSNP RS ID rs9820942—physical position 64560013)-C(dbSNP RS ID rs6780659—physical position 64595571)-A(dbSNP RS ID rs6445415—physical position 64602006)-T(dbSNP RS ID rs11721258—physical position 64605119)-A(dbSNP RS ID rs11707584—physical position 64612402)-G(dbSNP RS ID rs7652817—physical position 64614313)-T(dbSNP RS ID rs13079218—physical position 64617371)-A(dbSNP RS ID rs9819183—physical position 64620883), were given the value of 1, while all other sequences were given the value of 0. 
         [0070]    Gen-expression assays were performed with whole blood by qRT-PCR. Cells were resuspended, after red cell lysis, in 400 μl MagNApure Lysis buffer (Roche Applied Science, Mannheim, Germany) and lysates were stored at −80° C. until analysis. An automated sample preparation system (MagNA-Pure, Roche Applied Science, Mannheim, Germany) was used for mRNA isolation according to the manufactures protocol. The elution volume was set to 50 μl. An aliquot of 8.2 μl RNA was reverse transcribed using a first strand cDNA synthesis kit (Roche Applied Science, Mannheim, Germany) and oligo-(dT) as primer using the manufacturer&#39;s protocol in a thermocycler. After termination of the cDNA synthesis, the reaction mix was diluted to a final volume of 500 μl and stored at −20° C. until polymerase chain reaction (PCR) analysis. Parameter specific primer sets optimized for the LightCycler (Roche Applied Science, Mannheim, Germany) were developed and purchased from SEARCH-LC GmbH (Heidelberg, Germany). The PCR was performed with the LightCycler FastStart DNA Sybr Green I kit (Roche Applied Science, Mannheim, Germany) according to the protocol provided in the parameter specific kits. RNA input was normalized by the average expression of the two housekeeping genes β-actin and Cyclophilin B. The data was used as adjusted transcripts per μl cDNA. 
         [0071]    Analysis of released proteins was performed by ELISA in supernatants of whole blood cultures by using commercially available kits (Diaclone, Pelikine and Luminex) according to the manufacturer&#39;s protocols. Whole blood cultures were sedimented by centrifugation after 24 h of incubation at 37° C. and supernatants were kept at −80° C. until assay. The data was used as pg/ml protein concentration. 
         [0072]    Any other change of cellular marker associated with degranulation can be utilized to detect and quantify the degranulation efficacy and status induced by IgG exposure. Representatives of such NK cell granulae (lytic lysosomes) compounds are the proteins perforin and granzymes (the latter proteases, more specifically granzyme B), which can be quantified by for instance antigen detection systems like ELISA or direct enzymatic tests (for enzymes and proteases). The increased expression of CD107a is a typical indicator of NK degranulation. Using lipopolysaccharide (bacteria derived) in a whole blood assay system and thereby mimicking a patho-physiological situation, both IFN-gamma and CXCL10 are up-regulated on mRNA transcript (number) and protein (release) level. It was found that in the presence of added immunoglobulin (upon stimulation with LPS), the increase of CXCL10 was reduced by immunoglobulins as compared to the control without immunoglobulins, whereas no relative reduction was observed for IFN-γ. 
         [0073]    In general, the monitored signal is measured by methods known to the expert, like specific detection by using a labeled antibody, fragment or affinity ligand in flow cytometry (like FACS, fluorescent-activated cell sorting). 
         [0074]    Moreover, these parameters can be combined with assays on single nucleotide polymorphisms (SNP) like Interleukin-2 receptor (IL-2R), interleukin-7 receptor (IL7-R), and CD58 or with assays for genotyping indicating the patients different genetic background. 
         [0075]    All those analytical results were correlated with the outcome of the study, differentiation between patients responding to IgG-treatment (“responders”) and non responding patients (“non-responders”), and subjected to Linear Discriminant Analysis (LDA) for determination of most relevant parameters for prediction of a person&#39;s susceptibility to IgG treatment. After identification of useful parameters several LDA-scores with high predictive value were established, as displayed by the following examples. Analytical results were introduced in respective formula for LDA-Sore calculation in values and dimensions as indicated in the general assay description. Many examples were established by a random subset of responders and non-responders (indicated in the figures as “Learning Set”) of approximately the same size while the complement subset (“Validation Set”) was tested with the established formula. And both subsets were also of similar sizes.

         [0097]    This method allows the identification of persons responding/non-responding to any immunoglobulin product suitable for in vivo use such as those applied intravenously, subcutaneously, intramuscularly, ocularly, intrathecially, orally, topically or inhalably for diseases which are in principle accessible to immunoglobulin treatment, such as immune mediated inflammatory diseases, autoimmune diseases, allergies, graft-versus-host reactions and prevention of transplant rejection; any kind of multiple sclerosis or any other demyelinating neurological disease; or relapsing-remitting multiple sclerosis. 
         [0098]    The method also permits to predict the probability of a relapse of a MS patient and/or the rate of progression of the disease in terms of disability and or functioning of the patient as measured by clinical scales such as, but not limited to, the expanded disability status scale (EDSS), in particular lupus erythematosus, rheumatoid arthritis or intestinal/bowel diseases such as Crohn&#39;s disease, myositis or recurrent abortion. 
         [0099]    This method can additionally be used for facilitating the approval or recommendation of immunoglobulins by health authorities for the treatment of any kind of multiple sclerosis or any other demyelinating disease or Lupus erythematosus, rheumatoid arthritis or intestinal/bowel diseases such as Crohn&#39;s disease, myositis or recurrent abortion.
