Summary
Systemic sclerosis (SSc) patients face increased mortality, with infections causing 2-9% of deaths. Digital ulcers and immunosuppression increase infection risk, particularly in intensive care settings.
Area of Science:
- Rheumatology
- Infectious Diseases
- Critical Care Medicine
Background:
- Systemic sclerosis (SSc) is a rare autoimmune disease associated with significantly reduced survival, particularly in diffuse forms involving organ damage.
- Infections represent a notable cause of mortality in SSc patients, accounting for 2-9% of deaths.
- Limited research specifically addresses the spectrum and impact of infections in SSc.
Purpose of the Study:
- To review and summarize the current understanding of infectious complications in Systemic Sclerosis.
- To highlight patient populations and clinical scenarios with increased infection risk in SSc.
- To discuss the implications of infections on prognosis and treatment strategies in SSc.
Main Methods:
- Literature review of studies focusing on infections in Systemic Sclerosis patients.
- Analysis of reported infectious complications, including digital ulcers and opportunistic infections.
- Examination of outcomes for SSc patients with infections, particularly those requiring intensive care or undergoing transplantation.
Main Results:
- Digital ulcers are a frequent source of infectious complications in SSc.
- Patients with interstitial lung disease (ILD) on immunosuppressants are at risk for opportunistic infections, though cyclophosphamide may mitigate this risk.
- Infections in SSc patients admitted to intensive care units generally have a poor prognosis.
- Lung and hematopoietic stem cell transplantation carry a high risk of fatal infections in SSc, although recent data suggest improved outcomes post-hematopoietic stem cell transplantation.
Conclusions:
- Infections are a significant contributor to morbidity and mortality in Systemic Sclerosis.
- Vigilant monitoring and management of infections, especially in patients with digital ulcers, organ involvement, or undergoing transplantation, are crucial.
- Further research is needed to optimize the prevention and treatment of infections in the SSc population.

01:23Rheumatic Heart Disease I: Introduction
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...
01:23Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:25Endocarditis II: Clinical Features of Infective Endocarditis
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
01:29Staphylococcal Skin Infections
Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...
01:26Rocky Mountain Spotted Fever
Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
01:19Hypersensitivity Reactions: Immune-Complex Reactions
Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum sickness, a systemic...
