Research on systemic sclerosis published by scientists at Wayne State University, Medical Department.(Clinical report)

According to recent research published in the American Journal of the Medical Sciences, "In some patients with systemic sclerosis (SSc), persistent bacterial infection involving dermal microvascular endothelial cells may result in endothelial injury, leading to the obliterative microvasculopathy typical of the disease. Alternatively, in some patients with SSc persistent bacterial infection involving activated dermal fibroblasts or other cells found in scleroderma skin might result in the fibrosing features of this disease."

"In this study, we investigated bacterial infection in skin in patients with SSc. Chlamydiae of many species are known to undergo persistent infection. Highly sensitive and specific PCR assays targeting chromosomal DNA sequences from C. trachomatis and C. pneumoniae were used to screen skin biopsy samples from each of 18 patients and 26 control individuals. Additional screening was performed using a highly sensitive ''pan-bacteria'' PCR screening system. All patient and control samples proved to be PCR-negative for both chlamydial species. Similarly, all patient and control samples were PCR-negative when the broad range pan-bacteria assay system was used," wrote M.D. Mayes and colleagues, Wayne State University, Medical Department (see ...
