10 out of 10 in 2013 – My favourite 10 Rheumatology Articles in 2013
With Christmas and New Year celebrations now over, you’ve had your dose
of the Top 10 songs for the year end. Here are my favourite 10 papers from 2013.
I have chosen original papers and have not included reviews, recommendations or
meta-analyses. I have also focused on clinical papers as I could make another
list of basic science papers. There are many other papers which are worthy of
mention but to keep to 10, here is my list. I provide a short synopsis of each
paper. For further details, please refer to the original references.
10. The effect of vitamin D supplementation on
inflammatory and hemostatic markers and disease activity in patients with
systemic lupus erythematosus: a randomized placebo-controlled trial.
Abou-Raya A, Abou-Raya S, Helmii M. J Rheumatol.
2013 Mar;40(3):265-72. Epub 2012 Dec 1.
This paper assesses vitamin
D status in patients with SLE and determined alterations in inflammatory and
haemostatic markers and disease activity before and after vitamin D
supplementation. This is done on the basis that Vitamin D has immunomodulatory
functions.
Patients with SLE received
either oral cholecalciferol 2000 IU/day or placebo for 12 months. Serum levels between 10 and 30 ng/ml were
classified as vitamin D insufficiency and levels < 10 ng/ml as vitamin D
deficiency. The mean 25(OH)D level at baseline was 19.8 ng/ml in patients
compared to 28.7 ng/ml in controls. The overall prevalence of suboptimal and
deficient 25(OH)D serum levels among
patients with SLE at baseline was 69% and 39%, respectively. Lower 25(OH)D
levels correlated significantly with higher SLE disease activity. At 12 months
of therapy, there was a significant improvement in levels of inflammatory and
haemostatic markers as well as disease activity in the treatment group compared
to the placebo group.
Vitamin D supplementation
in patients with SLE improves infflammatory and haemostatic markers and show a
tendency toward subsequent clinical improvement
9. Head-to-head comparison of subcutaneous abatacept
versus adalimumab for rheumatoid arthritis: two-year efficacy and safety
findings from AMPLE trial.

The second head to head
study of biologics in RA in 2013. This study compares over 2 years the safety,
efficacy and radiographic outcomes of subcutaneous abatacept (125 mg weekly)
versus adalimumab (40mg every 2 weeks), in combination with stable dose of
methotrexate (MTX).
The ACR 20, 50 and 70
responses at year 2 were 59.7%, 44.7% and 31.1% for abatacept and 60.1%, 46.6%
and 29.3% for adalimumab. There were similar rates of adverse events (AEs) and
serious adverse events (SAEs) but there were less discontinuations due to AEs,
SAEs, serious infections and fewer local ISRs with abatacept. In RA patients
with an inadequate response to MTX, subcutaneous abatacept and adalimumab were similarly
efficacious based on clinical, functional and radiographic outcomes. Overall,
AE frequency was similar in both groups
8. Surgery versus
physical therapy for a meniscal tear and osteoarthritis.
Katz JN, Brophy RH, Chaisson CE, de Chaves L, Cole
BJ, Dahm DL, Donnell-Fink LA, Guermazi A, Haas AK, Jones MH, Levy BA, Mandl LA,
Martin SD, Marx RG, Miniaci A, Matava MJ, Palmisano J, Reinke EK, Richardson
BE, Rome BN, Safran-Norton CE, Skoniecki DJ, Solomon DH, Smith MV, Spindler KP,
Stuart MJ, Wright J, Wright RW, Losina E. N Engl J Med. 2013 May
2;368(18):1675-84. Epub 2013 Mar 18.
This paper helps answer the
question whether arthroscopic partial meniscectomy for symptomatic patients
with a meniscal tear and knee osteoarthritis results in better functional
outcomes than nonoperative therapy. Symptomatic patients 45 years of age or
older with a meniscal tear and evidence of mild-to-moderate osteoarthritis on
imaging were randomly assigned to surgery and postoperative physical therapy or
to a standardized physical-therapy regimen
The mean improvement in the
WOMAC score after 6 months was 20.9 points in the surgical group and 18.5 in
the physical-therapy group (mean difference, 2.4 points). At 6 months, 51
active participants in the study who were assigned to physical therapy alone
(30%) had undergone surgery. The frequency of adverse events did not differ
significantly between the groups. There was no significant difference between
the study groups in functional improvement 6 months after randomization;
however, 30% of the patients who were assigned to physical therapy alone
underwent surgery within 6 months. The results at 12 months were similar to
those at 6 months.
7. Tocilizumab monotherapy versus adalimumab monotherapy
for treatment of rheumatoid arthritis (ADACTA): a randomised, double-blind,
controlled phase 4 trial.
Gabay C, Emery P, van Vollenhoven R, Dikranian A,
Alten R, Pavelka K, Klearman M, Musselman D, Agarwal S, Green J, Kavanaugh A;
ADACTA Study Investigators. Lancet.
2013 May 4;381(9877):1541-50.
One of the two head to head
biologic studies in RA from 2013. Tocilizumab 8mg/kg iv 4 weekly (an IL-6
receptor signaling inhibitor) monotherapy was superior to adalimumab
monotherapy 40mg sc 2 weekly for reduction of signs (DAS28 -3.3 in the
Tocilizumab group and -1.8 in the Adalimumab group) and symptoms of rheumatoid
arthritis in patients intolerant of Methotrexate at 24 weeks. The adverse event
profiles of tocilizumab (12% SAE) and adalimumab(10% SAE) were consistent with previous findings with
raised LDL-cholestrol and ALT in the Tocilizumab group.
6. Efficacy and safety of ustekinumab in patients
with active psoriatic arthritis: 1 year results of the phase 3, multicentre,
double-blind, placebo-controlled PSUMMIT 1 trial.
McInnes IB, Kavanaugh A, Gottlieb AB, Puig L, Rahman

PSUMMIT 1 Study Group. Lancet.
2013 Aug 31;382(9894):780-9. Epub 2013 Jun 13.
Introduces a new agent in
the treatment of psoriatic arthritis. Ustekinumab (monoclonal antibody directed
against IL-12/IL-23) 45mg or 90mg, significantly
improved active psoriatic arthritis compared with placebo (ACR 20 achieved in
42.4% in the 45mg group, 49.5% in the 90mg group and 22.8% in the placebo
group) and was maintained at week 52. The proportions of patients with adverse
events were similar in the ustekinumab (41.8%) and placebo (42.0%) groups at week 16.
5. Efficacy of certolizumab pegol on signs and
symptoms of axial spondyloarthritis including ankylosing spondylitis: 24-week
results of a double-blind randomized placebo-controlled Phase 3 study.

Rheum Dis. 2014 Jan 1;73(1):39-47. Epub 2013 Sep 6.
This paper evaluates the
efficacy and safety of certolizumab pegol (CZP) in patients with axial
spondyloarthritis (axSpA), including patients with ankylosing spondylitis(AS)
and non-radiographic axSpA (nr-axSpA). Patients with active axSpA were
randomised to placebo, CZP 200 mg every
2 weeks or CZP 400 mg every 4 weeks.
Baseline disease activity
was similar between AS and nr-axSpA. At week 12, ASAS20 response rates were
significantly higher in CZP 200 mg (57.7%) and CZP 400mg (63.6%) arms versus
placebo (38.3). At week 24, combined CZP arms showed significant (p<0.001)
differences in change from baseline versus placebo in BASFI (-2.28 vs -0.40),
BASDAI (-3.05 vs -1.05), and BASMI (-0.52 vs
-0.07). Improvements were observed as early as week
1. Similar improvements were reported with CZP versus placebo in both AS and
nr-axSpA subpopulations. Adverse events were reported in 70.4% vs 62.6%, and
serious adverse events in 4.7% vs 4.7% of All CZP versus placebo groups.
CZP rapidly reduced the
signs and symptoms of axSpA, with no new safety signals observed compared to
the safety profile of CZP in RA. Similar improvements were observed across CZP
dosing regimens and in AS and nr-axSpA patients.

1;369(5):417-27.
Provides choice and an alternative
agent for the treatment of patients with severe ANCA-associated vasculitis. This
paper shows 18-month efficacy of a single course of rituximab (375mg/m2
weekly for 4 weeks) as compared with conventional immunosuppression with
cyclophosphamide (3 to 6 months) followed by azathioprine (12 to 15 months) in
patients with severe (organ-threatening) antineutrophil cytoplasmic antibody
(ANCA)-associated vasculitis.
There was non-inferiority
of Rituximab (remission rate of 64% at 6 months, 48% at 12 months and 39% at 18
months) compared to continuous conventional immunosuppressive therapy (remission
rate of 53%, 39% and 33% at 6,12 and 18 months respectively) for the induction
and maintenance of remissions over the course of 18 months. There was no
significant between-group difference in adverse events.

25;369(4):307-18. Epub 2013 Jun 11.
A real world study
addressing a common scenario in clinic. This study compares conventional
therapy consisting of a combination of disease-modifying antirheumatic drugs
(methotrexate, sulphasalazine, hydroxychloroquine) with biologic agents
(etanercept) in patients with rheumatoid arthritis who have active disease
despite treatment with methotrexate.
Triple therapy (sulfasalazine
and hydroxychloroquine added to methotrexate) was noninferior to etanercept
plus methotrexate in patients with rheumatoid arthritis who had active disease
despite methotrexate therapy. Participants (27%) in both groups who switched
therapies at 24 weeks had improvement after switching. The change between
baseline and 48 weeks in the DAS28 was similar in the two groups (-2.1 with
triple therapy and -2.3 with etanercept and methotrexate. There were no
significant between-group differences in adverse events associated with the
medications.
2. Mortality in rheumatoid arthritis: the impact of
disease activity, treatment with glucocorticoids, TNFα inhibitors and rituximab
Listing J, Kekow J, Manger B, Burmester GR, Pattloch
D, Zink A, Strangfeld A. Ann Rheum Dis. 2013 Nov 29.
This paper investigates the
impact of disease activity, the course of the disease, its treatment over time,
comorbidities and traditional risk factors on
survival using data of the German biologics register
RABBIT were used.
During 31 378 patient-years
of follow-up, the standardised mortality ratio was 1.49. Patients with persistent,
highly active disease (mean DAS28 > 5.1) had a significantly
higher mortality risk (adjusted HR
(HRadj)=2.43) than patients with
persistently low disease activity (mean DAS28 < 3.2).
Poor function andtreatment with glucocorticoids > 5 mg/d was significantly
associated with anincreased mortality, independent of disease activity.
Significantly lower
mortality was observed in patients treated with
tumour necrosis factor α (TNFα)
inhibitors (HRadj=0.64), rituximab (HRadj=0.57), or
other biologics (HRadj=0.64), compared to those receiving methotrexate. To
account for treatment termination in patients at risk, an HRadj for patients
ever exposed to TNFα inhibitors or rituximab was calculated. This resulted in
an HRadj of 0.77.
RA patients with long-standing
high disease activity have increased risk of mortality. Effective control of
disease activity decreases mortality.
TNFα inhibitors and rituximab seem to be superior to conventional DMARDs in
reducing this risk.
1. Validation of the methotrexate-first strategy in
patients with early, poor-prognosis rheumatoid arthritis: results from a
two-year randomized, double-blind trial.
O'Dell JR, Curtis JR, Mikuls TR, Cofield SS, Bridges
SL Jr, Ranganath VK, Moreland LW; TEAR Trial Investigators. Arthritis Rheum.
2013 Aug;65(8):1985-94.
Adds to our understanding
of treatment strategies in RA (step up treatment vs. initial combination
treatment). Patients were randomized to on of 4 groups: immediate treatment
with MTX plus etanercept, immediate oral triple therapy (MTX plus sulfasalazine
plus hydroxychloroquine), or step-up from MTX monotherapy to one of the
combination therapies (MTX plus etanercept or MTX plus sulfasalazine plus
hydroxychloroquine). All treatment arms included matching placebos.
At week 24, subjects in the
2 immediate-treatment groups demonstrated a greater reduction in the DAS28-ESR compared
with those in the 2 step-up groups (3.6 versus 4.2). Between week 48 and week 102, subjects randomized to the
step-up arms had a DAS28-ESR clinical response that was not different from that
of subjects who initially received combination therapy, regardless of the
treatment arm. At week 102, there was a statistically significant difference in
the change in radiographic measurements from baseline between the group
receiving MTX plus etanercept and the group receiving oral triple therapy (0.64
versus 1.69). This study demonstrates that initial MTX monotherapy with the
option to step-up to combination therapy results in similar outcomes to
immediate combination therapy. Approximately 30% of patients will not need
combination therapy, and the 70% who will need it are clinically and
radiographically indistinguishable from those who were randomized to receive
immediate combination therapy.
