Summary
Systemic sclerosis patients face high mortality from comorbidities. Neoplasia, cardiovascular diseases, and polypharmacy significantly increase this risk, highlighting the need for a comprehensive comorbidome approach.
Area of Science:
- Rheumatology and Immunology
- Clinical Epidemiology
Background:
- Systemic sclerosis (SSc) is a severe, life-threatening autoimmune disease.
- Mortality in SSc is significantly influenced by co-occurring medical conditions (comorbidities).
- Understanding the 'comorbidome' is crucial for managing SSc patient outcomes.
Purpose of the Study:
- To map the prevalence of comorbidities in Systemic sclerosis patients.
- To investigate the relationship between specific comorbidities and mortality.
- To develop a comprehensive 'comorbidome' for SSc.
Main Methods:
- Retrospective, single-center observational study of 400 SSc patients.
- Data collection included demographics, organ involvement, and 14 predefined comorbidities.
- Survival analysis using Kaplan-Meier curves and Cox regression.
Main Results:
- A total of 74 out of 400 participants (18.5%) died during the study period.
- Neoplasia, cardiovascular diseases, and polypharmacy were significantly associated with increased mortality.
- SSc-specific lung and cardiac involvements were also linked to higher mortality rates.
Conclusions:
- The study successfully constructed the SSc comorbidome, identifying key mortality predictors.
- Cardiovascular diseases, neoplasms, and polypharmacy are critical comorbidities in SSc.
- Further large-scale validation is needed to develop a potential mortality scoring tool for SSc.

Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

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...

Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Rheumatic heart disease (RHD) management can be divided into two main strategies: prevention and long-term management.Primary PreventionPrimary prevention focuses on timely diagnosis and management of group A streptococcal pharyngitis to prevent acute rheumatic fever. The most widely used antibiotic for treating this condition is intramuscular benzathine penicillin G.Acute Rheumatic Fever TreatmentThe primary treatment goal for a patient diagnosed with acute rheumatic fever is to suppress the...

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...
