[Treatment of cardiovascular risk factors]

[Pharmacological treatment of rheumatoid arthritis and its comorbidities]

Due to therapeutic advances, rheumatoid arthritis (RA) today has developed into a satisfactorily treatable disease in most cases, with remission being the target of treatment. Early diagnosis with immediate treatment initiation following treat-to-target strategy is the key to a favorable long-term outcome. A guideline-directed treatment algorithm determines the use of conventional synthetic disease-modifying anti-rheumatic drugs (DMARD; e.g., methotrexate), biological DMARD, and targeted oral DMARD (Janus kinase inhibitors). Comorbidities-in particular cardiovascular and interstitial lung disease-affect 80% of RA patients and represent the leading causes for mortality. The choice of drug treatment is influenced by the presence of comorbidities.

Cardiovascular Comorbidity in Inflammatory Rheumatological Conditions

BACKGROUND

Approximately 1.5 million adults in Germany suffer from an inflammatory rheumatological condition. The most common among these are rheumatoid arthritis and spondyloarthritis-above all axial spondyloarthritis, including ankylosing spondylitis (Bekhterev's disease) and psoriatic arthritis. These systemic inflammatory diseases often affect the heart as well.

METHODS

This review is based on pertinent articles retrieved by a selective literature search, on current European guidelines, and on the authors' clinical experience.

RESULTS

Rheumatic inflammation of cardiac structures can manifest itself as pericarditis, myocarditis, or endocarditis. The heart valves and the intracardiac conduction system can be affected as well, leading to AV block. Functional sequelae, e.g., congestive heart failure, can arise as a consequence of any inflammatory rheumatic disease. The long-term mortality of rheumatic diseases is elevated predominantly because of the increased risk for cardiovascular comorbidities. The cardiovascular risk profile should therefore be re-evaluated regularly (e.g., at 5-year intervals) in cooperation with the patient's primary care physician. The cardiovascular manifestations of rheumatic disease, such as pericarditis, myocarditis, and vasculitis, are treated initially with high-dose glucocorticoids and then over the long term with maintenance drugs such as methotrexate and azathioprine. Biological agents are sometimes used as well.

CONCLUSION

In patients with inflammatory rheumatic diseases, the elevated cardiovascular risk should be kept in mind and preventive measures should be initiated early. This subject should be further studied in controlled trials so that the treatment options for patients with cardiac involvement can be evaluated.

[Biologics and further new drugs for rheumatic diseases since 2000]

BACKGROUND

Rheumatoid arthritis (RA), psoriatic arthritis and axial spondyloarthritis are severe diseases, which without adequate treatment lead to extremely reduced mobility, functional status and quality of life.

OBJECTIVE

The effects of biologics and further new antirheumatic drugs on the burden of disease.

METHODS

Evaluation of study results and register data dealing with the efficacy and safety of these drugs.

RESULTS

Biologics have been proven to dramatically improve the outcome of all three diseases and contributed to the fact that remission is a realistic target today. In addition, the cardiovascular risk and mortality in RA have been reduced and structural damage is considerably blocked by biologics. Recently Janus kinase (JAK) inhibitors contributed to the treatment possibilities in the same way. Biologics as well as JAK inhibitors offer an excellent safety profile and tolerability with infections being the most important risk.

CONCLUSION

With the availability of biologics and additional new drugs all three diseases have lost the status of difficult to treat diseases. Their usage according to the guidelines ensures that the burden of disease can been minimalized in most cases. The benefit-risk profile of these drugs has been shown to be excellent.
