Prognosis and treatment of mixed connective tissue disease

INTRODUCTION

Mixed connective tissue disease (MCTD) is a generalized connective tissue disorder that includes clinical features commonly seen in systemic lupus erythematosus (SLE), scleroderma, and polymyositis (referred to as overlap syndrome) (table 1) [1]. Almost any organ system can be involved in MCTD. There are, however, several clinical features that, taken together, suggest the presence of MCTD rather than another connective tissue disorder:

Raynaud phenomenon and swollen hands or puffy fingers

A high titer speckled pattern antinuclear antibody (ANA) (usually ≥1280)

The absence of severe renal and central nervous system (CNS) disease

More severe arthritis, which is sometimes deforming
