Evaluation of the Prognostic Role of the Systemic Immune Inflammation Index in Postmenopausal Osteoporosis

Study Overview
=================
Brief Summary
-----------------
This study is a retrospective case-control study. In the study, the data of 304 patients who were evaluated in our clinic between January 2017 and January 2020 with a pre-diagnosis or diagnosis of postmenopausal osteoporosis were retrospectively reviewed. Lumbar 1-4 and femoral neck bone mineral densitometry values T scores, ages, sedimentation, C-reactive protein, neutrophil, leukocyte and platelet levels, and mean platelet volume values of the patients were recorded. The neutrophil-lymphocyte ratio was calculated by dividing the neutrophil count by the lymphocyte count, and the platelet-lymphocyte ratio was calculated by dividing the platelet count by the lymphocyte count. The systemic immune inflammation index (SII) was calculated using the formula, SII = platelet count x neutrophil count / lymphocyte count. The aim of this study is to evaluate the prognostic value of the systemic immune inflammation index in postmenopausal osteoporosis and to examine the SII, N / L, PLT / L, MPV, sedimentation (ESR), C reactive protein (CRP), femur and lumbar BMD values and their relationships with each other.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Systemic immune inflammation index (SII) | Systemic immune inflammation index (SII) is a new index related to systemic inflammation calculated by the numbers of lymphocytes, neutrophils and platelets in peripheral blood defined in 2014. The systemic immune inflammation index (SII) is calculated using the formula, SII = platelet count x neutrophil count / lymphocyte count. | 1 month |
