Anti-inflammatory treatment
During the last decades, treatment opportunities in RA have evolved, especially by the introduction of biologic disease modifying anti-rheumatic drugs (bDMARDs)
which are potent anti-inflammatory agents
![Page 16: High grade inflammation and the lipid paradox ...static.livemedia.gr/livemedia/documents/al18169_us63_2016032116… · We evaluated if baseline lipid levels and -systemic inflammation](https://reader036.vdocuments.site/reader036/viewer/2022081407/60493ba6138dbf46f83a5828/html5/thumbnails/16.jpg)

Anti-inflammatory treatment
During the last decades, treatment opportunities in RA have evolved, especially by the introduction of biologic disease modifying anti-rheumatic drugs (bDMARDs)
However, controversies exist regarding the impact of bDMARDs on the risk of CVD in patients with RA

Biologic DMARDs
A systematic literature review suggested that treatment with TNF-i is associated with a decreased risk of CVD1
- register studies/cohort observations
- a recurrent problem with these studies are the lack of information on whether the anti-rheumatic medication consisted of - TNF-i monotherapy or - combination TNF-i+MTX 1Westlake SL et al, Rheumatology (Oxford) 2011; 50(3):518-31

Conclusion
Major heterogeneity exists in CVD event rates
across different countries among patients with
RA
Possible explanations include population
differences, referral bias, RA treatment effects,
statin and antihypertensive use
Development of an RA specific CVD risk
calculator must address these differences

Expanded CV risk prediction score for RA (ESR-RA) a CORRONA registry study
• Does not contain traditional risk factors • Lipids & Blood pressure
• Age, gender, diabetes, hyperlipidemia (y/n), hypertension (y/n), tobacco use (y/n)
• Baseline RA disease specific measures sign in the regression analyses and included in the model was:
– CDAI > 10 vs < 10
– MHAQ > 5 or < 5
– Daily prednisone use
– Disease duration > 10 yrs vs. less

Used 2013 ACC/AHA risk categories
< 7.5% and > 7.5% 10 year risk of a CVD event
When using the expanded calculator :
• 10.8% were reclassified from >7.5% to < 7.5%
• 8.5% were reclassified from < 7.5% to > 7.5%
Thus addition of disease specific factors in this risk calculator resulted in fewer patients beeing considered for statins
Extenal validaton is needed

Background inflammation and
lipid lowering effect
197 patients referred to the Preventive Cardio-Rheuma clinic obtained LDL-C goals
We evaluated if baseline lipid levels and -systemic inflammation in these patients were associated with the statin dose sufficient to achieve LDL-C targets
LDL-C targets: 1⁰ Prevention: < 2.5 mmol/L
2⁰ Prevention: < 1.8 mmol/L

the relation between baseline lipids and inflammation

Most interestingly..
The baseline inflammatory status and lipid levels in patients who did and did not obtain LDL-c goal were comparable
CRP/ESR: p-value 0.32 and 0.64 and
LDL-c/Total chol: p-value 0.20 and 0.83
This illuminates that inflammation did not influence achievement of lipid goals in patients with IJD

Conclusion
Patients with IJD referred to the Preventive Cardio-
Rheuma clinic had a high probability for the need of CV
prevention Supporting the importance and relevance of establishing
Preventive Cardio-Rheuma Clinics
Treatment to lipid targets was successful in ~90% on
less than 3 consultations Illustrating that LL medication as statins are effective and
safe in patient with IJD
Inflammation does not affect statin dose needed to
obtain recommended LDL levels

Conclusions
In patients with RA, Atorvastatin 40mg daily
compared to placebo resulted in:
– Significantly greater reduction of LDL
– A 34% (unadjusted) risk reduction for a major CVD event • In line with the CTT collaboration meta-analysis in other populations
– No increase in adverse events

Conclusions RORA study
Intensive lipid lowering with rosuvastatin induced regression of CP height and reduced LDL-c significantly in patients with IJD
Without any intervention, atherosclerotic lesions will with a high probability progress. We did not observe a progression of the carotid plaques over the 18 month study period in patients using bDMARDs and rosuvastatin treatment
Prospective randomized statin studies are warranted to reveal if height reduction of asymptomatic CP will have impact on future CV events

Overall Conclusions
RA patients have lower lipids, altered lipoprotein composition and function due to inflammation
Inflammation does not affect statin dose needed to obtain recommended LDL levels
LLT with statins is effective and can induce atherosclerotic regression
Primary and secondary prevention effects from RCT’s are sparce and further studies are warranted
