Long term efficacy and safety of cyclosporin versus parenteral gold in early rheumatoid arthritis: a three year study of radiographic progression, renal function, and arterial hypertension

Ulcerative colitis increases risk of hypertension in a UK biobank cohort study

OBJECTIVE

Inflammatory bowel disease (IBD) is not only a chronic inflammatory disorder of the gastrointestinal tract but also accompanied by systemic inflammation. The onset of hypertension is closely related to systemic inflammation. However, the relationship between IBD and hypertension has not been investigated. We aimed to investigate the potential association between IBD and the incidence of hypertension.

METHOD

We retrieved IBD onset and the incidence of hypertension from a public database UK Biobank. The association between the onset of IBD and subsequent incidence of hypertension was analyzed using a multivariate Cox regression analysis, and propensity score matching was performed for sensitivity analysis.

RESULT

Of a total of 281,064 participants included in the study, 2376 (0.8%) were diagnosed with IBD at baseline, and 20,129 (7.2%) in the whole cohort developed hypertension with a median follow-up duration of 8.1 years (interquartile range [IQR] 7.3-8.8 years). Patients with IBD had a higher cumulative risk of hypertension compared with general population (10.9% in ulcerative colitis [UC], 7.7% in Crohn's disease [CD], and 9.3% in IBD unclassified [IBD-U] vs. 7.1% in non-IBD, p < 0.001). Multivariate Cox regression analysis identified that UC, rather than CD or IBD-U, was independently associated with subsequent occurrence of hypertension (HR 1.30, 95% CI: 1.11-1.52, p = 0.001). In propensity matching analysis, UC also showed its robustness as a risk factor for the prediction of hypertension (HR 1.56, 95% CI: 1.21-2.03, p = 0.001).

CONCLUSION

In IBD patients, UC rather than CD is associated with a higher risk for the incidence of hypertension compared with general population. Close monitoring of hypertension might be required in clinical practice.

2018 update of the APLAR recommendations for treatment of rheumatoid arthritis

AIM

To update recommendations based on current best evidence concerning the treatment of rheumatoid arthritis (RA), focusing particularly on the role of targeted therapies, to inform clinicians on new developments that will impact their current practice.

MATERIALS AND METHODS

A search of relevant literature from 2014 to 2016 concerning targeted therapies in RA was conducted. The RA Update Working Group evaluated the evidence and proposed updated recommendations using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach, to describe the quality of evidence and strength of recommendations. Recommendations were finalized through consensus using the Delphi technique.

RESULTS

This update provides 16 RA treatment recommendations based on current best evidence and expert clinical opinion. Recommendations 1-3 deal with the use of conventional synthetic disease-modifying antirheumatic drugs. The next three recommendations (4-6) cover the need for screening and management of infections and comorbid conditions prior to starting targeted therapy, while the following seven recommendations focus on use of these agents. We address choice of targeted therapy, switch, tapering and discontinuation. The last three recommendations elaborate on targeted therapy for RA in special situations such as pregnancy, cancer, and major surgery.

CONCLUSION

Rheumatoid arthritis remains a significant health problem in the Asia-Pacific region. Patients with RA can benefit from the availability of effective targeted therapies, and these updated recommendations provide clinicians with guidance on their use.

The Use of Cyclosporine A in Rheumatology: a 2016 Comprehensive Review

Cyclosporine A, an inhibitor of calcineurin, exerts an immunomodulator action interfering with T cell activation. Even though novel therapeutic tools have emerged, CyA still represents a suitable option in several clinical rheumatology settings. This is the case of refractory nephritis and cytopenias associated with systemic lupus erythematosus. Furthermore, CyA is a valued therapeutic tool in the management of uveitis and thrombophlebitis in course of Behçet's disease. Topical CyA has been proven to be beneficial in the dry eye of Sjogren's syndrome, whereas oral treatment with CyA can be considered for the severe complications of adult onset Still's disease. CyA provides a therapeutic option in psoriatic arthritis, being rather effective in skin disease. CyA is currently regarded as a second-line option for patients with inflammatory myopathies refractory to standard regimen. CyA is used even in paediatric rheumatology, in particular in the management of juvenile dermatomyositis and macrophage activation syndrome associated with systemic juvenile idiopathic arthritis. Importantly, CyA has been shown to suppress the replication of HCV, and it can thus be safely prescribed to those patients with chronic hepatitis C. Noteworthy, CyA can be administered throughout the gestation course. Surely, caution should be paid to CyA safety profile, in particular to its nephrotoxicity. Even though most evidence comes from small and uncontrolled studies with few randomised controlled trials, CyA should be still regarded as a valid therapeutic tool in 2016 rheumatology.

Pediatric spinal trauma

Pediatric spinal trauma is unique. The developing pediatric spinal column and spinal cord deal with direct impact and indirect acceleration/deceleration or shear forces very different compared to adult patients. In addition children are exposed to different kind of traumas. Moreover, each age group has its unique patterns of injury. Familiarity with the normal developing spinal anatomy and kind of traumas is essential to correctly diagnose injury. Various imaging modalities can be used. Ultrasound is limited to the neonatal time period; plain radiography and computer tomography are typically used in the acute work-up and give highly detailed information about the osseous lesions. Magnetic resonance imaging is more sensitive for disco-ligamentous and spinal cord injuries. Depending on the clinical presentation and timing of trauma the various imaging modalities will be employed. In the current review article, a summary of the epidemiology and distribution of posttraumatic lesions is discussed in the context of the normal anatomical variations due to progressing development of the child.

Management of cardiovascular risk in patients with rheumatoid arthritis: evidence and expert opinion

The risk of cardiovascular morbidity and mortality is increased in rheumatoid arthritis. The classical cardiovascular risk factors, including smoking, hypertension, dyslipidaemia, insulin resistance and diabetes mellitus, obesity and physical inactivity do not appear to explain the excess cardiovascular risk in rheumatoid arthritis, although they do contribute, albeit in a different way or to a lesser extent, to rheumatoid arthritis in comparison with the general population. A very important link between rheumatoid arthritis and cardiovascular disease is inflammation as it plays a key role in all stages of atherosclerosis: from endothelial dysfunction to plaque rupture and thrombosis. It also has an influence on and accentuates some traditional cardiovascular risk factors, such as dyslipidaemia, obesity and insulin resistance. To date, the exact pathophysiologic mechanism by which this relation between cardiovascular disease and rheumatoid arthritis can be explained is not completely clear. Cardiovascular risk management in rheumatoid arthritis is mandatory. Unfortunately, the way this should be done remains a point of discussion. In this review issues regarding cardiovascular risk in rheumatoid arthritis and its management will be addressed, according to evidence presented in the latest studies and our own experience-based opinion.

The effect of methotrexate on cardiovascular disease in patients with rheumatoid arthritis: a systematic literature review

OBJECTIVES

Patients with RA have an increased prevalence of cardiovascular disease (CVD). This is due to traditional risk factors and the effects of chronic inflammation. MTX is the first-choice DMARD in RA. We performed a systematic literature review to determine whether MTX affects the risk of CVD in patients with RA.

METHODS

We searched Medline, Embase, Cochrane database, database of abstracts of reviews of effects, health technology assessment and Science Citation Index from 1980 to 2008. Conference proceedings (British Society of Rheumatology, ACR and EULAR) were searched from 2005 to 2008. Papers were included if they assessed the relationship between MTX use and CVD in patients with RA. Two reviewers independently assessed each title and abstract for relevance and quality.

RESULTS

A total of 2420 abstracts were identified, of which 18 fulfilled the inclusion criteria. Two studies assessed the relationship between MTX use and CVD mortality, one demonstrated a significant reduction in CVD mortality and the second a trend towards reduction. Five studies considered all-cause CVD morbidity. Four demonstrated a significant reduction in CVD morbidity and the fifth a trend towards reduction. MTX use in the year prior to the development of RA decreased the risk of CVD for 3-4 years. Four studies considered myocardial infarction, one demonstrated a decreased risk and three a trend towards decreased risk with MTX use.

CONCLUSION

The current evidence suggests that MTX use is associated with a reduced risk of CVD events in patients with RA. This suggests that reducing the inflammation in RA using MTX not only improves disease-specific outcomes but may also reduce collateral damage such as atherosclerosis.

Nanoparticles for optical molecular imaging of atherosclerosis

Molecular imaging contributes to future personalized medicine dedicated to the treatment of cardiovascular disease, the leading cause of mortality in industrialized countries. Endoscope-compatible optical imaging techniques would offer a stand-alone alternative and high spatial resolution validation technique to clinically accepted imaging techniques in the (intravascular) assessment of vulnerable atherosclerotic lesions, which are predisposed to initiate acute clinical events. Efficient optical visualization of molecular epitopes specific for vulnerable atherosclerotic lesions requires targeting of high-quality optical-contrast-enhancing particles. In this review, we provide an overview of both current optical nanoparticles and targeting ligands for optical molecular imaging of atherosclerotic lesions and speculate on their applicability in the clinical setting.

Hypertension in rheumatoid arthritis

RA associates with an increased burden of cardiovascular disease, which is at least partially attributed to classical risk factors such as hypertension (HT) and dyslipidaemia. HT is highly prevalent, and seems to be under-diagnosed and under-treated among patients with RA. In this review, we discuss the mechanisms that may lead to increased blood pressure in such patients, paying particular attention to commonly used drugs for the treatment of RA. We also suggest screening strategies and management algorithms for HT, specific to the RA population, although it is clear that these need to be formally assessed in prospective randomized controlled trials designed specifically for the purpose, which, unfortunately, are currently lacking.

Efficacy and tolerability of valdecoxib in treating the signs and symptoms of severe rheumatoid arthritis: A 12-week, multicenter, randomized, double-blind, placebo-controlled study

OBJECTIVE

This study compared the efficacy and tolerability of the cyclooxygenase-2-selective inhibitor valdecoxib with the nonselective NSAID naproxen and with placebo in treating severe rheumatoid arthritis (RA).

METHODS

This 12-week, multicenter, randomized, double-blind, placebo-controlled study compared the efficacy and tolerability of valdecoxib 10 mg QD (n = 170) or naproxen 500 mg BID (n = 167) with placebo (n = 171) in treating the signs and symptoms of severe RA. Study patients were aged >or=18 years and were diagnosed as having RA for >or=6 months that was stable due to a treatment regimen. Severe RA was defined as a physician's and patient's global assessment of disease activity of fair, poor, or very poor at baseline; >or=6 tender or painful joints; >or=3 swollen joints; >or=45 minutes of morning stiffness; a visual analog scale pain rating of >or=40 mm; or increases since baseline in these measures. Efficacy outcome measures included the percentage of patients achieving an American College of Rheumatology Responder Index 20% (ACR-20) at weeks 1, 6 and 12. Adverse events (AEs) were graded by the investigator as mild, moderate, or severe at weeks 1, 6, and 12.

RESULTS

Of the 508 patients randomized, 340 completed the study. The study groups were comparable for age, ethnic origin, weight, height, and concomitant medications, but the naproxen group had significantly more men (29% [49/167]) than the valdecoxib (18% [31/170]) and placebo (16% [27/171]) groups. The percentage of patients achieving an ACR-20 response was significantly greater in the valdecoxib and naproxen treatment groups (58.8% [100/170] and 60.8% [101/166], respectively) than in the placebo group (39.6% [67/169]) at week 12 (both, P < 0.001). The percentage of patients achieving an ACR-20 response was significantly greater in the naproxen group than in the placebo group at both week 1 (53.6% [89/166] vs 37.9% [64/169]; P = 0.003) and week 6 (64.5% [107/166] vs 46.7% [79/169]; P = 0.001), and in the valdecoxib group compared with placebo at week 1 (52.9% [90/170]; P = 0.008) but not at week 6. Patients in the valdecoxib and naproxen groups had significantly improved efficacy compared with placebo in most of the other secondary assessments of inflammation, pain, and function. The incidence of AEs was similar in all groups (valdecoxib, 54.1% [92/170]; naproxen, 55.4% [92/166]; and placebo, 52.9% [90/170]).

CONCLUSION

Valdecoxib 10 mg QD administered over 12 weeks was significantly better than placebo and similar to naproxen 500 mg BID in treating the signs and symptoms of severe RA in these patients.

Lip hypertrophy secondary to cyclosporine treatment: a rare adverse effect and treatment considerations

Gingival hypertrophy is a well-known and extensively documented undesirable side effect of cyclosporine in posttransplant patients. However, severe lip enlargement associated with cyclosporine is less recognized and has seldom been reported in the literature. Lip enlargement may lead to social, physical, and psychological stress, especially in the older childhood and adolescent age groups. We present a case of marked lip hypertrophy and concomitant gingival hypertrophy secondary to cyclosporine (Neoral) treatment in a pediatric bilateral lung transplant recipient. We also discuss the various side effects and treatment considerations available including more recent substitution therapy. Cyclosporine has most effectively and conclusively enabled transplantation of solid organs by reducing transplant-associated morbidity. We believe clinicians should be knowledgeable and aware of lip hypertrophy associated with cyclosporine use. This rare and less understood adverse effect should be recognized during the clinical evaluation of the posttransplant patient.

Basic immunosuppressive drugs outside solid organ transplantation

Immunosuppressive drugs are the backbone of solid organ transplantation. The introduction of new immunosuppressive drugs led to improved patient and organ survival rates. Nowadays, acute rejection can be reduced to a minimum. Individualization and avoidance of drug-related adverse effects became a new goal to achieve. The potency of immunosuppressive drugs makes them attractive for use in various autoimmune diseases; therefore, the experience on immunosuppressive drugs outside the field of organ transplantation is analysed in this review.

Local immunomodulation with CD4 and CD8 antibodies, but not cyclosporine A, improves osteogenesis induced by ADhBMP9 gene therapy

This study was designed to see if immunosuppression achieved using local application of cyclosporine A (Cs. A) or CD4 and CD8 antibodies would improve bone formation following intramuscular injections of human BMP-4 and BMP-9 adenoviral vectors (ADhBMP4 and ADhBMP9) in Sprague-Dawley rats. Cs. A was injected into the thigh muscle. After 2 days, ADhBMP4, ADhBMP9, and the antibodies were separately injected into the left and right rear legs. At this time, the number of CD4+/CD3+ cells was significantly lower and the number of CD8+/CD3+ cells higher in the Cs. A group than in the control group (P < 0.01). The total number of white blood cells 3 days following injection of CD4 and CD8 antibodies was significantly lower than that before the injection (P < 0.01). At 4 weeks after the viral and antibody injections, mean bone volumes at the ADhBMP9 treatment sites were 0.29 +/- 0.01 cm3 in the viral control group, 0.17 +/- 0.03 cm3 in the Cs. A-ADhBMPs group, and 0.59 +/- 0.07 cm3 in the antibodies-ADhBMPs group. ADhBMP4 did not induce new bone formation in any group. This study demonstrates that local immunomodulation may improve the osteogenic potential of bone morphogenetic protein gene therapy in the clinical setting.

Infliximab in active early rheumatoid arthritis

OBJECTIVE

To examine the impact of the combination of infliximab plus methotrexate (MTX) on the progression of structural damage in patients with early rheumatoid arthritis (RA).

METHODS

Subanalyses were carried out on data for patients with early RA in the Anti-TNF Therapy in RA with Concomitant Therapy (ATTRACT) study, in which 428 patients with active RA despite MTX therapy received placebo with MTX (MTX-only) or infliximab 3 mg/kg or 10 mg/kg every (q) 4 or 8 weeks with MTX (infliximab plus MTX) for 102 weeks. Early RA was defined as disease duration of 3 years or less; 82 of the 428 patients (19%) met this definition. Structural damage was assessed with the modified van der Heijde-Sharp score. The changes from baseline to week 102 in total modified van der Heijde-Sharp score were compared between the infliximab plus MTX groups and the MTX-only group.

RESULTS

The erosion and joint space narrowing scores from baseline to week 102 in the cohort of patients with early RA decreased significantly in each infliximab dose regimen compared with the MTX-only regimen. Consistent benefit was seen in the joints of both hands and feet.

CONCLUSIONS

Infliximab combined with MTX inhibited the progression of structural damage in patients with early RA during the 2 year period of treatment. Early intervention with infliximab in patients with active RA despite MTX therapy may provide long term benefits by preventing radiographic progression and preserving joint integrity.
