[Mechanism of poor responsiveness to therapy of bacterial infection in patients with connective tissue diseases].
Infectious complications are important factors for poor prognosis of connective tissue diseases (CTD). 33% of the fatal cases with CTD were caused by infectious complications in our study. It was characteristic of infectious complications with CTD, that pneumonia was recognized in all CTD, especially, commoner in PSS, PM and OL, and frequently caused a fatal outcome. Gram negative bacillus, for instance E. coli and K. pneumoniae were frequently detected as pathogens. On the other hand, methicillin resistant Staphylococcus aureus (MRSA) was increased recently, and tuberculosis, especially atypical tuberculosis, such as, miliary and cutaneous forms were also recognized. The risk factors in the development of bacterial infections is considered to be intricately correlated with cellular and humoral immunodeficiency due to CTD or steroid hormones.
