Abstract:
Background. Studies in anti-neutrophil cytoplasmic antibody (ANCA)-associated
vasculitis have revealed biomarkers distinguishing active disease from remission. We
conducted a systematic literature review to elucidate the potential of these markers in
prediction of disease activity.
Rationale/Aim. We tried to corroborate the abundant expression of the most promising
markers. In our cross-sectional analysis, a biomarker panel comprising CRP and
urinary MCP-1 yielded a sensitivity and specificity of 76% (AUC 0.89). While CRP may
be influenced by gender, atherosclerotic burden or infectious complications, MCP-1 is
a major chemoattractant abundantly regulated in several autoimmune disorders. Thus,
the “best” panel is useless in assessing disease activity in daily routine.
This project aims to investigate novel biomarker candidates, which may hold great
promise in improving this diagnostic dilemma. In addition, we aim to investigate
markers of endothelial dysfunction, tissue injury & remodelling longitudinally which may
allow the prediction of disease relapses and thus would be favourable for daily clinical
routine in the management of these complex patients.
Design. Samples from 30 patients suffering from ANCA-associated vasculitis and large
vessel vasculitis each as well as 20 healthy controls will be followed up/evaluated
prospectively.
Methods. Plasma biomarkers will be measured using commercially available ELISA
kits.
Study period. This study will be initiated on January 1st, 2017. Ethics approval has
already been obtained (see below). We expect submission of a manuscript draft end of
2017.

Background:
Granulomatosis with polyangiitis (GPA, previously known as Wegener’s
granulomatosis) and microscopic polyangiitis (MPA) are subtypes of primary systemic
vasculitides associated with anti-neutrophil cytoplasm antibodies (ANCA). They are
grouped together as ANCA-associated vasculitis, a potentially devastating, relapsing-
remitting autoimmune inflammatory condition present in approximately 10-30 per
100,000 people in Europe [1]. During active disease, endothelial injury and repair play
a pivotal role. Damage of the affected organs leads to a significant morbidity with long-
term complications such as polyneuropathy or impaired kidney function. Minimisation
of relapse risk is one of the major aims in the long-term management of patients with
systemic vasculitides. A lack of biomarkers correlating with the current disease status
is hampering physician’s care by the risk of induction of severe complications in terms
of over-immunosuppression or further organ damage attributable to active vasculitis in
case of inadequate treatment. Current methods to assess disease activity (Birmingham
Vasculitis Activity Score [2] and ANCA [3]) are unreliable in this perspective.
In common with other vasculitis syndromes, endothelial dysfunction as measured by
impaired response to vasodilating agents or Laser-Doppler flowmetry is a key hallmark
in newly diagnosed or relapsing patients. Patients with active disease have an
increased risk to develop venous thromboembolic events with a frequency of
approximately 7 per 100 patient-years, compared to an overall risk of 0.15-0.31 per 100
patient-years in the general population [4]. Moreover, the odds-ratio of cardiovascular
events is 6.7 in ANCA-associated vasculitis compared to the general population [5], an
excess again not accounted for by traditional risk factors but likely to be related to
ongoing chronic inflammation and vasculitis activity sub-optimally controlled in patients.
ANCA-associated vasculitis is associated with accelerated atherosclerosis [5], arterial
stiffness [6], diffuse endothelial dysfunction [7] and reduced nitric oxide bioavailability.
Improving the cardiovascular morbidity and mortality is one of the unmet needs in the
management of patients with ANCA-associated vasculitis. Novel immunosuppressive
agents have been licensed for the treatment of active ANCA-associated vasculitis, such
as rituximab [8], but its effects on vascular function has yet to be determined. We are
currently participating in a trial comparing the effects of this monoclonal antibody
directed against CD20 bearing cells on vascular dysfunction to a cyclophosphamide-
based induction therapy. Preliminary results from this observational study presented in
abstract form favour rituximab in terms of improving endothelial dysfunction (Casian A
5
et al., Rituximab and Vascular Function in ANCA Associated Vasculitis, 17th Vasculitis
Workshop, London 2015).
Biomarkers are representing potential candidates to improve diagnostic accuracy and
disease activity assessment. In the last decade several large scale biomarker studies
have been conducted to identify an ideal blood biomarker reflecting general disease
activity and urinary biomarkers were studied to elucidate disease activity in patients
with renal involvement. Lally et al. highlighted that biomarkers are needed to guide the
management of patients with ANCA-associated vasculitis [9]. In addition, the authors
recommended that further insights into aetiopathogenesis (especially using “-omic”
approaches) are needed to develop improved diagnostic tools (i.e. in combination with
biomarkers).
In a first attempt, we performed a systematic review of the literature on to date
published biomarkers, calculated a fold-change expression (see Table 1) and
performed a validation study in a cross-sectional cohort of well phenotyped patients.
Moreover, the aim of our study was to establish a reliable biomarker panel reflecting
disease activity.

In our cross-sectional analysis, CRP, complement C3a and C5a, IL-18 bp, urinary
MCP-1 and C5a showed significantly higher expression levels in active AAV compared
to inactive patients (all P≤0.01). Using Salford Predictive Modeling software, the most
significant independent predictors and cut-off points for active disease were as follows:
MCP1-levels in urine and CRP levels. Together, these two biomarkers yielded a
sensitivity and specificity of 76%. The receiving operator curve (ROC) reached a level
of 0.89 (Figure 1, Kronbichler A, Nephrol Dial Transplant 2016; 31:930-6).
Figure 1. Using Salford Predictive Modeling software, the most significant independent predictors and cut-
off points for active renal disease were as follows: MCP-1 levels in urine > 0.53 ng/ml and CRP levels >
21.6 mg/l. Adding these two biomarkers sensitivity was 76 % and specificity was 76 %. The ROC curve
reached a level of 0.89.

Project Aim / Research Rationale:
There is a clear need to extend our knowledge regarding biomarker expression in
ANCA-associated vasculitides. In a preliminary set of experiments, we performed a
proteomic approach to investigate potential future biomarker targets. We could
elucidate an abundant expression of transport proteins, such as haptoglobin, which was
32-fold over-expressed in patients with active ANCA-associated vasculitis compared to
patients in remission (see Table 2). Since proteomic analyses are not reliable for daily
routine investigations, other technical methods, such as protein detection using ELISA
kits are more appropriate.
The main aims of the underlying project are
a) to corroborate the findings of the preliminary proteomic approach
b) to evaluate further potential candidates, which might not be detected by classic mass
spectrometry methods
c) to find an ideal biomarker panel associated with the disease activity state
d) to test this panel in a subset of relapsing patients
The validity of these investigations should be confirmed in further larger follow-on
investigations. Little is known regarding expression of these candidates in vasculitides
per se. Elevated haptoglobin levels have been reported in vasculitis patients (GPA,
along with patients suffering from giant cell arteritis and Takayasu arteritis). In addition,
in vitro experiments demonstrated that haptoglobin induced angiogenesis, correlated
with disease and angiogenic activity and was partially inhibited by antibodies directed
against haptoglobin in sera from patients. It was hypothesised that haptoglobin may
actively participate in tissue repair by stimulating neo-angiogenesis in vasculitis [10].
Several other proteins of interest were identified through our preliminary results. Among
the most promising candidates, which are involved in cardiovascular disorders, are
Lectin-like oxidized low-density lipoprotein receptor 1 (Lox-1), Lipoprotein-associated
phospholipase A2 (Lp-PLA2), asymmetric dimethylarginine (ADMA) and endoglin
(CD105). Moreover, classic growth factors contributing to neo-angiogenesis in tumour
cells, which is also a hallmark of vasculitis, will be included in our analysis, including
platelet derived growth factor-BB (PDGF-BB) and hepatocyte growth factor (HGF). A
novel marker of inflammation, supporting neutrophil trafficking, represents Midkine [11].
This is of particular interest, since neutrophils play a pivotal role in AAV and neutrophil
infiltration of endothelial cells is one important step initiating inflammation. Monach and
8
colleagues have studied matrix metalloproteinase expression extensively, but did not
investigate their marker of interest during disease relapse [12]. We would study these
markers, namely MMP-3, TIMP-1 and CXCL13, along with the identified markers in our
preliminary experiments (talin-1 and vinculin) in a set of well selected patients.
Serum levels of these biomarkers will be measured using an enzyme-linked
immunosorbent assay (ELISA). The expression of biomarkers will be measured during
an active disease state (prior to initiation of specific immunosuppressive measures,
such as cyclophosphamide or rituximab), during remission (sample collection, 6 months
post first collection) prior to and at the time of relapse. Moreover, we plan to include
two comparator groups, consisting of a) patients with large vessel vasculitides (giant
cell arteritis and Takayasu arteritis), having signs of systemic inflammation combined
with endothelial dysfunction, and b) healthy age-matched controls.
Table 2. Preliminary results (derived from a proteomic approach).
This design will allow the following comparisons (Figure 2):
1. F vs G: cases vs controls at relapse 2. F/C vs G/D: change from remission to relapse between cases and controls 3. F vs E: to assess whether markers of relapse change before relapse becomes clinically
apparent 4. Analysis of A and B will permit a secondary assessment of the extent to which markers
of relapse may also identify de novo disease.
Figure 2. Different analysis strategies are depicted.
Our aim is to analyse 30 samples of patients with ANCA-associated vasculitis
during active disease, during remission, prior to and at the time of relapse. Moreover,
Marker Fold-change (active versus remission)
Haptoglobin 32.00
á1-Actin (cardiac muscle-1) 10.00
Talin-1 10.00
Vinculin 6.00
9
a similar proportion of samples from patients with large vessel vasculitides should be
collected. We expect to finish sample collection until mid of 2017.
We recognise that, for biomarker discovery, large sample sizes are desirable. The
sample size for the present study is determined by the estimated difference of marker
expression comparing active disease to remission (3-fold difference, respective power
of 85%). Although the number of relapse samples might be lower, this pilot trial will
allow concrete calculation of follow-up studies. We expect to apply for samples
collected from the PEXIVAS trial, which is currently ongoing and aims to recruit
approximately 700 patients to perform further biomarker studies. Clearly, our aim is to
apply to another funding body once this pilot trial is finished.
Study Hypothesis:
1) We hypothesise that markers of angiogenesis, tissue injury and repair are useful in
the differentiation of diverse disease activity states and the prediction of disease
relapse in patients with ANCA-associated vasculitis.
2) We hypothesise to propose a biomarker panel, which will replace currently used
biomarkers, including ANCA.
