I PRINTO REPORT

A. Planned PRINTO prospective JDM study-Ruperto and Ravelli (Genoa)

1.  5 year trial

2. Objective: Determine which treatment regimen is associated with the lowest

occurrence of flares and toxicities.

3.  Prednisone alone versus prednisone + cyclosporine versus prednisone +

methotrexate

4.  Muscle biopsy at diagnosis will be optional.

5.  Treatment protocol:

a. 3 days pulse of methyprednisolone at 30 mg/kg/day

cyclosporine (up to 5 mg/kg/day) versus prednisone + weekly methotrexate.

c. Prednisone use will be formalized and regimented with full dose for

the first month with prednisone taper over the next 5 months at 0.2

mg/kg/day. Then in next 18 months prednisone will be lowered

stepwise to 0.1 mg/kg/day. Each center will use the same tapering schedule.

d. Response measures will include:

1.) Time to response of 25%, 50%, 75% improvement in first six months.

7. No financial support yet.

 

D. PRINTO prospective, randomized trial evaluating the optimal way to utilize methotrexate

during clinical remission of JIA. Ruperto and Ravelli (Genoa)

 

Question: How long to continue methotrexate once clinical remission is achieved? It’s

believed that 50% of children with JIA do relapse after methotrexate is stopped. Relapses

also appear to be independent of the duration of  treatment with mtx

 

1.       Protocol

a.  Group A methotrexate is stopped at 6 months after clinical remission achieved.

b.  Group B methotrexate is stopped at 12 months.

c.  Patients are evaluated q 3 months for 1 year for a total of 9 visits.

 

2.   Criteria for remission

a.  No systemic features for 3 months-no abnormal exam findings, no increased
CRP/ESR

b.  No recent intraarticular corticosteroids.

c.  Low dose pred-NSAID ok

3.   Blood samples to be taken.

4    Thus far 128 patients are entered from 70 centers (1/2 from London, Utrecht)

5.   One hundred Euro will be paid to each patient at the end of the study.

E.  Ongoing report on Infliximab study- (Other data presented last year)-Ruperto

1.   Initially would appear that fewer side effects with 3 mg/kg dose and many more SAE’s
with 6 mg/kg than 3 mg/kg by 19 to 5.

2    Infusion reactions much higher in 3 mg than 6 mg 9.1 to 3.0

3.   Antibodies 3x more in 3 mg/kg than 6 mg/kg, antibody to infliximab-3 with high

      titers 1:20480; association possible between antibody titers and infusion reactions.

4.   No TB noted in first 52 weeks.

5.   Serious infections did occur, e.g., pneumonia.

6.   Efficacy profile the same between groups.

7.   Side effects overall good.

8.   3 mg/kg group had more problems with infusion side effects though drug

      levels were as good as the 6 mg/kg group and PK’s better.

9.   6 mg/kg group has more total adverse events with no added efficacy.

 

II PReS Working Groups

A.      Lupus Working Group-Angelo Ravelli (Pavia)

1.   Lupus studies at PReS in coordination with PRINTO

a. Introduction

There has been a mild decrease number of scientific work among PReS members noted before this meeting. Several reasons may explain this trend:

1)   There is difficulty of studying lupus in general.

2)       Adult research in SLE may take priority in funding.

3)       Adult research in SLE often includes adolescents.

4)       Juvenile SLE has relatively low prevalence.

Most studies in the past have been retrospective and cross-sectional and few have used standardized definitions and outcome instruments. It is time to focus on prospective studies. We would like to begin a long term (60 months) prospective data collection via the internet as a SLE registry that will be coordinated by PRINTO.

b. Objectives of the new study as proposed:

1)   To establish a multinational, multicenter study

2)   To assess long term outcome of juvenile SL$E

3)   To describe clinical manifestations, lab, clinical course,

treatment modalities and complications.

4)   To assess impact on prognosis of the different treatment

modalities currently utilized for SLE.

5)   To identify early prognostic factors.

c. Inclusion criteria

1)   Newly diagnosed patients under 18 years of age

2)   SLE by ACR criteria (1992)

3)   Study approved by the IRB and ethical board

4)   Appropriate consents signed.

d. An internet based data sheet will be utilized for ease of use.

3)   Global assessment (VAS) by parent/patient

4)   Child Health Questionnaire (CHQ) to be filled out by parent

      for the child

i. Additional data to be collected every six months

1)   Major complications

2)   Mortality data including if cause of death, due to SLE

      YES NO Unclear

3)   SLICC/ACR DI

4)   Global assessment of damage by the physician

5)   Global assessment of activity by parent

 

2.   Antiphospholipid syndrome registry-Tadej Avcin (London)

A. Introduction

The International Registry for Pediatric Patients with the Antiphospholipid  

Syndrome was begun 1 ½ years ago at the European Phospholipid Meeting in

London. The rationales included:

1.   Though pediatric reports and studies have been unusual, it

      is believed that APLA problems are becoming more frequent in Europe.

2.       There also are important differences from adults with APLA, e.g.,

                     effects of smoking and atherosclerosis.

               3.   There appear to be unique factors in children to evaluate,

                      e.g.,

a. prevalence of specific disease manifestations

b. increased incidence of infection.

c. effects of long-term APLA therapy in kids

B. Objectives

1.   Organize an international and European registry.

2.   Study long term outcomes.

C. Organization

1.   Collaboration of PRINTO and European Forum on

      antiphospholipid antibodies.

2.   It will be an online, internet-based registry.

3.   Confidentiality issues will be addressed.

D. Inclusion. Criteria

1.   Diagnosis of APS before 18th year

2.   Preliminary clinical criteria-vascular thrombosis; Lab criteria;

                                                      anticardiolipin antibody of IgG and/or IgM (IgG and

                                                      IgM medium to high positive) or positive lupus anticoagulant.

E. Study data sheet on internet

The data sheet included demographic data, disease related data

(arterial, venous, small vessel thromboses, neurological diseases,

hematological disorders, skin disorders, and other disorders). It

also will include the APLA lab findings with the detection methods

used as well as the SLE diagnostic assays utilized. The treatment

and outcome data will also be collected.

Please e-mail Dr. Avcin if you are interested in participating in this study.

 

III JUVENILE DERMATOMYOSITIS (JDM) STUDY GROUP-C. Pikington (London)

Discussion topics

A. IVIG study

B. Muscle biopsy scoring project

C. Allied health professionals report

D. IMACS project + Rituximab study

E. Criteria for DM diagnosis

F. Classification of myopathies

 

 

  1. IVIG

                        Survey of 50 studies-most centers start with steroids. IVIG  only occasionally

                        used. In discussions with members, it was agreed that an IVIG study appears to

                        be too expensive. Plus there does not seem to be sufficient interest in what may

                        be a difficult study. A study comparing cyclosporin A and methotrexate may be

                        more pertinent. A pilot trial has been begun and contact Dr. Pilkington if you are

                        interested.

 

  1. Grading of muscle biopsies

There are few if any pediatric rheumatologists who are experts in interpreting

muscle biopsies. So muscle histopathologists were needed. The pathologists

were recruited from Europe and the USA. The goal of this muscle biopsy project

was to develop a muscle biopsy scoring system which has never been done

for JDM. To develop this scoring, it was necessary to convene a muscle

biopsy consensus meeting.  For this meeting, a cooperative retrospective,

multicenter study of juvenile dermatomyositis patients who have had muscle

biopsies was needed.

 

The initial Biopsy Consensus Conference was held in March 2005 in London. It

took one day to agree upon a scoring system. The second day the scoring

system was tried out on muscle biopsies. The pathologists were introduced to

the VAS tool which they adjusted to. It turned out to be easy to agree upon

whether a biopsy was technically acceptable but there was less agreement on

the findings of each biopsy. The 2nd meeting of histopathologists is planned in

March 2006. The study remains a work in progress. Funding is being provided

by several UK myositis organizations.

 

C.   Allied Health Professional report

A survey was performed on physical therapy (PT) interventions in early JDM-PT’s in 19 countriesreplied-50% had no PT intervention in active phase of JDMS-It is tentatively planned to repeat the study with more centers.

A new survey will look at another part of PT intervention, the need for a fatigue assessment/measurement.  This tool should be easy, practical, and quick.  Eventually complementary core outcome measures for PT are needed that might fit well with the PRINTO JDM outcome measures

 

  1. IMACS core study-Lisa Ryder and Daniel Eisenberg-multicenter study is ongoing.

1. JDM outcome measure is being tested that includes among others:

a.  Physician global activity: 10 cm VAS

b.  Patient or parent VAS

c.  Manual muscle testing

d   Physical function-outcome

e.  Laboratory  tests

Definition of improvement is: 3/6 criteria improved by >20%

No more than 2 worse by >20% (not including the manual muscle testing)

 

2. Rituximab study at NIH

This is an international study involving both adult and childhood JDM. This study is limited to

refractory patients with JDM.  The dose will be 750 mg/m2 at weeks 1 and 2. It includes two treatment
groups.

Group A: Rituximab in week 1 and 2

Group B: Placebo infusions at weeks 1 and 2.

This group will receive Rituximab at 9 weeks.

Study Investigators had a meeting in Sept 2005, beginning patient recruitment in autumn 2005.   

 

E.   Criteria for diagnosis of JDM

Initial survey on diagnostic criteria was sent out to 110 centers. So far only 42

replies have been received, a 38 % response rate. Three criteria had wide

agreement: muscle weakness, rash, and muscle enzyme elevation. There was 

little agreement after that, though the EMG and MRI tests were close to

obtaining the necessary number of responses to be a criterion. There

was interest in a formal study on criteria in the 41/42 centers that responded.

Thirteen centers could provide all categories of cases-paper cases that are

retrospective. Both JDM and overlap JDM diagnostic criteria would be

analyzed. Brian Feldman in Toronto is coordinating this study. He is willing

to collate and analyze the data. An internet data form will be used. No funding is

available yet. Expect that an e-mail from Dr. Pilkington will sent out soon.

 

 

      F.   Classification study of JDM/overlap syndromes

There has been no past consensus on the meaning of JDM overlap syndromes. Now there

is a huge and complicated effort on classification for JDM and other muscle diseases in adults and children that will address overlap as well as all myopathy categories. It will be a multispecialty consensus study including adult and pediatric neurologists as well as adult and

pediatric rheumatologists. Classification will include inflammatory myositis, limb girdle dystrophies, fasculoscapular dystrophy, drug toxin myopathy, infectious myopathy, and others. Funding is from the ACR and EULAR The next meeting will be in November 2005.

 

IV. RATIO registry organization

A.      French collaborative group includes internist and pediatric organization of rheumatologists, gastroenterologists, pulmonologists, infectious disease specialists, and general internists.

B.    The collaborative group surveys for side effects of TNF therapy in France especially for infections such as
TB, Listeria, aspergillus, pneumocytis, and others.

C.   The group is particularly alert for lymphoma.

D.   Methods

1.  Prospective registry since February 2004

2.  Surveying for severe bacterial infections, opportunistic infections, and lymphoma.

3.  Participants included 474 centers in France.

4.  Mail was sent out with 4 reminders per yea.

5.  Reports made obligatory to govt

6.  Confirmed infection or lymphoma was checked thoroughly.

7.  When medicine was given is important, e.g., if medicine was given > 2 years ago, the infection
is not counted. (Not so lymphoma)

8.  Three committees set up to review and verify validity of reports.

E.   Present results

1.  137 cases of infection or malignancy

2.  Sixty infections were severe bacterial infections.

3.  Sixty-three infections were opportunistic.

4.  Thirteen lymphomas were noted.

5.  Only 2 children in the 137 cases

6.  The majority were adults with rheumatoid arthritis or spondyloarthropathy

7.  Nineteen were on infliximab, 25 etancecept, 9 Humira

8.  Thirty-one episodes of bacterial sepsis.

9.  Opportunistic Infections (20 TB, 15 viral, 13 legionnaires, 4 aspergillosis, 3 pneumocytis)

F.   Tuberculosis

1.  Tuberculosis: in first 12 months, 13 cases noted (8 RA, 5AS)-on infliximab 7,
Humira 6, etanercept 1.

2.  This data suggests that despite guidelines on anti-TNF medications, TB is still

      a major problem. Guidelines should be revisited and perhaps not disregarding the 5 mm positive PPD.

G.   Lymphoma

1.  Thirteen patients developed lymphoma during the year (4 Hodgkins, 1 diffuse B cell, 1 Mast B cell
lymphoma with Sjogrens (10 RA, 2 AS, 1 Sjogrens)

H.   Conclusions

1.  Surveys must be national

2.  Participation must be made mandatory and keep pushing them

3.  Good example btw cooperation of gov and medicine and pharmo

4.  Led to change in length of treatment for prophylaxis to make it longer and reduction  of PPD
positivity back to 5 mm
