What do simple hematological parameters tell us in patients with systemic sclerosis?

Area of Science:

• Rheumatology
• Hematology
• Internal Medicine

Background:

• Systemic sclerosis (SSc) is a complex autoimmune disease with varied clinical presentations.
• Autoantibodies and systemic inflammation markers are studied for predicting organ involvement in SSc.
• Complete blood count (CBC) parameters as predictors of SSc severity and organ involvement require further investigation.

Purpose of the Study:

• To investigate the utility of CBC parameters in assessing organ involvement in SSc.
• To determine if CBC parameters, alongside clinical features and autoantibodies, enhance risk estimation for SSc complications.
• To explore the association between CBC-derived inflammatory ratios (NLR, MLR, PLR) and organ involvement in SSc.

Main Methods:

• A case-control study involving 130 adult SSc patients and 129 healthy controls.
• Retrospective collection of epidemiological, clinical, laboratory, and radiological data from patient records.
• Analysis of CBC parameters, including neutrophil/lymphocyte (NLR), monocyte/lymphocyte (MLR), and platelet/lymphocyte (PLR) ratios.

Main Results:

• Platelet/lymphocyte ratio (PLR), neutrophil/lymphocyte ratio (NLR), and monocyte/lymphocyte ratio (MLR) correlated with organ involvement.
• Hemoglobin, lymphocyte count, and mean platelet volume were significant predictors for interstitial lung disease risk.
• Low lymphocyte counts indicated higher pulmonary hypertension risk, while specific neutrophil volume predicted gastrointestinal involvement.

Conclusions:

• Basic hematological parameters derived from CBC are effective in predicting SSc-related organ involvement.
• CBC parameters offer a simple and accessible method for risk stratification in systemic sclerosis.
• These findings support the integration of CBC analysis into SSc management for early detection of organ complications.
