Case Report: Systemic Sclerosis After Covid-19 Infection.

Area of Science:

• Immunology
• Rheumatology
• Infectious Diseases

Background:

• Coronavirus disease (COVID-19), caused by SARS-CoV-2, is a respiratory illness with potential long-term complications.
• Emerging evidence suggests COVID-19 can trigger autoimmune responses, including autoantibody production.
• Autoimmune diseases may manifest or worsen in genetically susceptible individuals post-COVID-19 infection.

Observation:

• A 47-year-old man experienced mild COVID-19 symptoms, testing positive for SARS-CoV-2.
• Three weeks post-infection, he developed symptoms suggestive of systemic sclerosis (SSc), including skin manifestations, Raynaud's phenomenon, and gastrointestinal issues.
• Laboratory tests revealed positive antinuclear antibodies (ANA) with a nucleolar pattern and positive anti-PM/Scl antibodies. High-resolution computed tomography (HCRT) indicated early interstitial lung disease (ILD).

Findings:

• The patient met the ACR/EULAR classification criteria for SSc, with a total score of 10.
• This case represents the first documented instance of new-onset systemic sclerosis following a COVID-19 infection.
• The findings suggest a potential causal link between SARS-CoV-2 infection and the development of SSc.

Implications:

• SARS-CoV-2 infection may be a trigger for systemic sclerosis in susceptible individuals.
• This expands the spectrum of known autoimmune complications associated with COVID-19.
• Further research is warranted to understand the mechanisms underlying COVID-19-induced SSc and its long-term prognosis.
