To evaluate if the elevated systemic immunity-inflammation index (SII) is a marker of severity in patients with recently diagnosed rheumatoid arthritis at the Víctor Lazarte Echegaray Hospital (VLEH) Materials and Methods: An analytical observational study of 151 medical records of patients diagnosed with rheumatoid arthritis treated in the outpatient clinic of the Víctor Lazarte Echegaray Hospital was carried out. For this, the following inclusion criteria were considered: patients of both sexes, over 18 years of age, treated at the VLEH rheumatology outpatient clinic and with a recent diagnosis of RA by EULAR criteria (greater than or equal to 6 points), with evaluation of disease activity by DAS28-PCR and those who have a complete blood count and PCR taken within the last weeks prior to diagnosis. And the following exclusion criteria: patients on immunosuppressive therapy (last 30 days) or with a malignant neoplasia, pregnancy, liver cirrhosis or chronic kidney disease (stage 4 or 5), diabetes mellitus, HIV/AIDS; likewise, those with a diagnosis of: fibromyalgia, lupus erythematosus or severe osteoarthritis are also excluded. To determine the ISS, the quotient formed by dividing the product of platelets and neutrophils by the total number of lymphocytes from the same blood count was calculated; and to determine if this index can be used as a severity marker for rheumatoid arthritis, it will be compared with the DAS 28 already known in this pathology. To evaluate the cut-off points, Student's T was used to compare the quantitative data between the RA severity and non-severity groups. For the analysis of the categorical variables, Pearson's Chi-square was used, determining significance if p<0.05, In addition, the strength of association was determined by calculating the odds ratio and 95% confidence interval. Results: Of the 151 patients with newly diagnosed rheumatoid arthritis, the Systemic Inflammatory Immunity Index and DAS28 agreed in 78 cases for the result of “non-severe” rheumatoid arthritis, while the agreement for “severe” rheumatoid arthritis cases was 53. cases, representing 51.7% and 35.1% respectively; being a total of 131 cases in total (86.8%), which allows us to affirm that there is significant agreement between both markers, and can be classified as considerable agreement. Conclusion: The elevated Systemic Immunity-Inflammation index can be used as a marker of severity in patients with recently diagnosed rheumatoid arthritis.
