Use of Steroid in Rheumatology

2Rheumato C Soe

Long Term Steroid The millennium brings with it the 50th

anniversary of Hench’s discovery that corticosteroids might be used to treat rheumatoid arthritis.

Attitudes towards such use have waxed and waned since then.

Initial hope that steroids might dramatically alter the long term course of the disorder gave way to a recognition of serious adverse effects, that accompany high dose treatment.

The use of low dose corticosteroids in arthritis remains highly controversial.

3Rheumato C Soe

A recent survey in general practice found that 1.4% of patients aged over 54 were using corticosteroids at a mean dose of 8mg daily

Although rheumatologists claim to use less the audit had found use (as great as 80%).

Regulation of Gene Expression by Glucocorticoids Following ligand binding, HSP90 and several

other of the associated proteins dissociate, and the GR is directed into the nucleus where it can interact with specific DNA sequences within the regulatory regions of affected genes.

These short DNA sequences that are recognized by the activated glucocorticoid receptor are termed glucocorticoid-responsive elements (GREs)

and provide specificity to the induction of gene transcription by glucocorticoids.

The currently acknowledged consensus GRE DNA sequence is GGTACAnnnTGTTCT,

Improve symptom A Dutch trial comparing prednisolone 10 mg

daily with placebo as an adjunct to intramuscular gold reported clinical improvement in both groups over 12 weeks;

this was greatest among those trearted with prednisolone.

The Arthritis and Rheumatism Council trial randomised 128 patients to prednisolone 7.5 mg daily or placebo in additon to non-steroidal and disease modifying agents.

Symptomatic benefit was maintained for only 6-9 months of the two year follow up.

9Rheumato C Soe

Meta-analysis A meta-analysis of the effectiveness of low

dose corticosteroidsa in rheumatoid arthritis based on 9 of 34 studies identified in a rigorous search strategy

compared the effectiveness of prednisolone to either placebo or active drug controls (aspirin, chloroquine, or deflazacort).

Although corticosteroids tended to be better at reducing the number of tender or swollen joints and the number of erythrocyte sedimentation rate, these differences were not significant.

10Rheumato C Soe

Retard Erosion!! Whether corticosteroids attenuate the

progression of erosive damage is also unresolved.

In the Arthritis and Rheumatism Council study showed prednisolone had a pronounced and significant (p<0.004) effect on the development of hand erosions in patients with rheumatoid arthritis of less than two year’s duration.

11Rheumato C Soe

Gotzsche and Johansen report a further meta-analysis comparing prednisolone at a dose of 2.5-15 mg daily with palacebo or non-steroidal anti-inflammatory drugs

They show that at these dose prednisolone is much more effective than non-steroidal drugs at improving joint tenderness, pain, and grip strength.

12Rheumato C Soe

Concern

To the practising rheumatologist the great disincentive to using short term low dose prednisolone is not concern about lack of anti-aiflammatory effect

but the worry that stepping treatment down may be difficult, with the consequence

that the patient is exposed to the risk of adverse effects.

CPT

Corticosteroid Pulse Therapy

14Rheumato C Soe

Corticosteroid Pusle Therapy in Active Rheumatiod ArthritisBy Bas L.A.M. Weusten, Johannes W.G.Jacobs, and Johnnes W.J.Bijisma

In an attempt to reduce the frequent and potentially servere side effects of long-term oral steroid therahy, the intermittent intravenous administration of high doses of corticosteroids (corticosteroid pulse therapy, CPT) was introduced.

CPT was reported to be effective against renal allograft rejection.

15Rheumato C Soe

Later reports showed that patients with idiopathic glomerulomephritis and glomerulonephritis associated with systemic lupus erythematous respond well to this from of treatment.

In the course of the past decade,CPT also has been used to treat rheumatoid arthritis (RA).

16Rheumato C Soe

Different Regimens (For Acute Flare Up)

Many studies of the efficacy of (different regimens of) CPT in RA have been performed

1,000 mg of methylprednisolone intravenously in 10 RA patients once a month for 6 consecutive months

Tender joint counts, walking time, and grip strength improvement were still apparent more than 7 months after the last corticosteriod infusion.

CPT did not influence the progression of erosions followed radiologically

17Rheumato C Soe

Forster et al reported long-lasting clinical improvement in their RA patients after a regimen of

1,000 mg of methylprednisolone given on 3 alternate days and 1,000 mg intravenously on 3 consecutive days

The benefit lasted more than 1 year erythrocyte sedimentation rate and C-

reactive protein level, was of shorter duration (about 2 weeks)

whereas methylpredisolone is metabolized and excreted within a few days

18Rheumato C Soe

CPT IN CONJUNTION WITH DISEASE-MODIFYINGANTIRHEUMATIC DRUG THERAPY(Bridging) Neumann et al investigated the

possibility of maintaining the clinical improvement induced by intiating (new) diseasemodifying antirheumatic drug (DMARD) therapy concomitantaly.

They found that a regimen of 3 *1,000mg methylpredisolone intravenously on alternate days,

19Rheumato C Soe

If started simultaneously with a new DMARD, was able to bridge the gap between the start and effect of at least two different DMARDs: D-penicillamine and sulphasalazine.

In 1988, a similar effect of CPT in conjunction with sodium aurothiomalate was demonstrated.

In contrast, we found that CPT (3x1,000 mg methylperdnisolone) is unable to bridge the gap between the start and the effect of azathioprine.

20Rheumato C Soe

COMPARISON OF THE EFFICACY OF DIFFERENT REGIMENS OF CPT

After intial reports on the efficacy of high-dose intravenous CPT, several investigators studied the effects of reduced doses of methylpred-nisolone.

Radia and Frust compared the efficacies of a single dose of 1,000 mg of methylprednisolone given intravenously,

320 mg of methylprednisolone administered intravenously,

and 320 mg of methylprednisolone given intramuscularly.

21Rheumato C Soe

Shipley et al claimed a significantly better response to a single intravenous 1,000-mg dose of methylprednisolone than to 500 mg and 40 mg.

Dexamethasone (200 mg),given via an intravenous infusion on alternate days over a 5-day period was also tried.

22Rheumato C Soe

They found that 85% of patients treated with 1,000 mg of methylprednisolone considered the therapy worthwhile,

compared with only half the patients receiving lower dosages.

Several authors have compared high-dose oral prednisolone with intravenous methylprednisolone.

23Rheumato C Soe

In conclusion, different regimens of CPT are of clinical benefit for patients with severe, intractable RA.

As for bridging the gap between the start and effect of a newly introduced DMARD, the effect of low-dose or oral CPT has not been proved,

Recommended regimens consisting of three 1,000-mg doses of methylprednisolone.

EBM The Cochrane Controlled Trial Registry,

MEDLINE, and EMBASE were searched for RCTs of treatment for DPLN.

All available RCTs of patients with biopsy-proven DPLN were included, and data were extracted for overall mortality, end-stage renal disease, doubling of serum creatinine level, relapse, major infection, herpes zoster infection, ovarian failure, malignancy, and bladder toxicity.

32Rheumato C Soe

Twenty-five of 920 articles identified were eligible RCTs and were included.

The majority compared cyclophosphamide or azathioprine plus steroids versus steroids alone.

cyclophosphamide combined with steroids remains the best option to preserve renal function

35Rheumato C Soe

36Rheumato C Soe

The relatively high mineralocorticoid activity of cortisone and hydrocortisone, and the resulting fluid retention, make them unsuitable for disease suppression on a long-term basis.

However, they can be used for adrenal replacement therapy

hydrocortisone is preferred because cortisone requires conversion in the liver to hydrocortisone.

37Rheumato C Soe

Betamethasone and dexamethasone have very high gluococorticoid activity in conjunction with insignificant mineralocorticoid activity.

This makes them particularly suitable for high-dose therapy in conditions where fluid retention would be a disadvantage (e.g. cerebral oedema).

STEROIDTREATMENT CARD

I am a patient on STEROID treatment which must not be stopped suddenly.

If you have been taking this medicine for more than three weeks, the dose should be reduced gradually when you stop taking steroids unless your doctor says otherwise.

39Rheumato C Soe

Read the patient information leaflet given with the medicine.Always carry this card with you and show it to anyone who treats you (for example a doctor, nurse, pharamacist or dentist).

For one year after you stop the treatment, you must mention that you have taken steriods.

If you become ill, or if you come into contact with anyone who has an infectious disease, consult your doctor promptly. If you have never had chickenpox, you should avoid close contact with people who have chickenpox or shingles. If you do come into contact with chickenpox, see your doctor urgently.

Make sure that the information on the card is kept up to date.
