Persistent Infection Study
Researchers have long suspected an infection component may be involved as the trigger of some cases of scleroderma and there is an ongoing study about persistent infection as a possible cause of scleroderma.
Serious Infections in People With Systemic Sclerosis: A National US Study. Outcomes in people with SSc hospitalized with serious infections have improved over time. PubMed, Arthritis Res Ther, 2020 Jun 29;22(1):163.
Suspected adverse effects after human papillomavirus vaccination: a temporal relationship. Our study has shown that the period of HPV vaccination considerably overlapped with that of unique postvaccination symptom development. PubMed, Immunol Res, 2018 Dec;66(6):723-725.
Reversible IgA deficiency after severe Gram-negative bacteria infection in a patient with systemic sclerosis. Although the mechanism of secondary IgAD is still vague, its association with autoimmune diseases including SSc and also with bacterial infection is discussed. (Springerlink) Masato Yagita.

Case Report: Borrelia-associated early-onset morphea: A particular type of scleroderma in childhood and adolescence with high titer antinuclear antibodies? Results of a cohort analysis and presentation of three cases. We observed a statistically highly significant association between morphea, serologic evidence of Borrelia infection, and high-titer antinuclear antibodies when disease onset was in childhood or adolescence.

Case Report: HIV infection associated with scleroderma: report of two new cases. In this report, we describe the rare association of linear scleroderma of the four limbs in two HIV patients also affected with virus C hepatitis. J A Mosquera, J Clin Pathol.
A lot of the controversy surrounding nanobacteria has to do with its very name, in that some researchers do not believe that it represents a life form and thus cannot properly be named "bacteria", because the research on its purported nucleic acid has not been completed yet. Thus, some believe that "nanoparticles" would be a better description for it.
This is a very new field of research which is highly controversial, however it has recently attracted the attention of researchers at the Mayo Clinic and NASA. Nanobacteria have been found in kidney stones, Alzheimer's disease, heart disease, prostatitis, and some cancers.
Lack of evidence for bacterial infections in skin in patients with systemic sclerosis. While some caveats apply, the data presented here do not support the contention that persistent bacterial infections play an important role in the pathogenesis of systemic sclerosis (SSc). Am J Med Sci.
The interaction between anti-Ro/SSA and anti-La/SSB autoantibodies and anti-infectious antibodies in a wide spectrum of auto-immune diseases (AID): another angle of the autoimmune mosaic. Our findings support the concept of interplay between infectious agents and autoimmunity, such as the plausibility of an infectious agent that trigger the immune system to produce specific antibodies which will later result in a unique group of AID. PubMed, Clin Exp Rheumatol, 2017 Nov-Dec;35(6):929-935.
Human cytomegalovirus (HCMV) UL44 and UL57 specific antibody responses in anti-HCMV-positive patients with systemic sclerosis. Anti-HCMV UL57 antibodies are universally present in anti-HCMV-positive patients with SSc, while those against UL44 are rarely seen. PubMed, Clin Rheumatol, 2017 Apr;36(4):863-869.
Increased immunoreactivity against human cytomegalovirus UL83 in systemic sclerosis. Immunoreactivity to UL83 HCMV is frequent and strong in patients with SSc, implying a possible pathogenic role for this disease. PubMed, Clin Exp Rheumatol, 02/27/2017.
