Recruiting
Conditions
Idiopathic Inflammatory Myopathies
Interventions
Drug: Intravenous Infusion
Registration Number
NCT03092180
Lead Sponsor
University of Sao Paulo
Brief Summary

As a T2T, our patients with idiopathic inflammatory myopathies will receive pulse therapies with methyprednisolone and/or human intravenous immunoglobulin, or only methyprednisolone at disease onset.

This scheme is an internal routine protocol of our Service.

Detailed Description

To compare two groups of patients as described in Brief Summary.

Primary Outcome Measures
NameTimeMethod
Physician Global ActivitySix months

This partially validated tool measures the global evaluation by the treating physician of the overall disease activity of the patient at the time of assessment using a 10 cm. visual analogue scale and a 5 point Likert scale.

Patient/Parent Global Activity -Six months

This partially validated tool measures the global evaluation by the patient, or by the parent if the patient is a minor, of the patient's overall disease activity at the time of assessment using a 10 cm. visual analogue scale.

Myositis Disease Activity Assessment ToolSix months

After local anesthesia, a cutaneous incision will be made in lateral thigh face. The biopsy will be done using the Bergstrom needle. Histological (hematoxylin and eosin)/immunohistochemical (CD4, CD8, CD68, CD20, C5b-9, MHCI, MHCII, CD31) analysis will be performed in muscle samples (at baseline and after 12 weeks) in all patients (present study)

Manual Muscle TestingSix months

This partially validated tool assesses muscle strength using manual muscle testing (MMT). A 0 - 10 point scale is proposed for use. An abbreviated group of 8 proximal, distal, and axial muscles performs similarly to a total of 24 muscle groups, and is also proposed for use for research studies.

Health Assessment QuestionnaireSix months

Define the health assessement questionnaire. Pontuaction: 0.00-3.00

Muscle EnzymesSix months

This partially validated tool measures the serum activities of at least 2 of the 4 muscle-associated enzymes including creatine phosphokinase (CK), the transaminases (ALT, AST), lactate dehydrogenase (LD) and aldolase.

Secondary Outcome Measures
NameTimeMethod
Side effects to treatment (glucocorticoid, immunosuppressants and/or human intravenous immunoglobulin)Six months
