- Ages 18 to 65 years
- All sexes
- Adult, Older adult
Study population: A total of 35 (17 female and 18 male) patients with brucella spondylodiscitis and 37 (26 female and 11 male) type 1 Modic Changes (MCs) were enrolled in the study. Diagnoses of brucella spondylodiscitis and type 1 MCs were supported by microbiological, serological, and radiological diagnotic tools. Patients' hematological parameters were recorded, and hematological inflammatory indexes (NLR: neutrophil/lymphocyte; MLR: monocyte/lymphocyte; PLR: platelet/lymphocyte; NLPR: neutrophil/(lymphocyte*platelet); SII (neutrophil*platelet/lymphocyte): systemic inflammatory index; SIRI (neutrophil*monocyte/lymphocyte): systemic inflammatory response index; AISI (neutrophil*platelet*monocyte/lymphocyte): aggregate index of systemic inflammation. ) were derived from baseline CBC tests.

About this study
Hematological inflammatory indices (Table 2) are currently very popular and have diagnostic, prognostic, and predictive, roles in various diseases. Considering their promising roles, we hypothesized that hematological inflammatory indices may have a distinctive value between brucella spondylodiscitis and type 1 Modic Changes (MCs). If the hypothesis is valid, early diagnosis-differential diagnosis-treatment processes may become easier and more successful. Given that hematological inflammatory indices are faster, practical, simpler, inexpensive, and easily accessible indicators, they may be more appropriate tools in differentiation between brucella spondylodiscitis and type 1 MCs.
Read the detailed description
This is a retrospective comparative study focusing to distinguish between brucella spondylodiscitis and type 1 MCs considering hematological inflammatory indexes. Patients' data were obtained from Hospital Information Systems, between 2020 to 2024. A total of 35 patients with brucella spondylodiscitis and 37 type 1 MCs were enrolled in the study. Diagnoses of brucella spondylodiscitis and type 1 MCs were supported by microbiological, serological, and radiological diagnostic tools. Patients' hematological parameters were recorded, and hematological inflammatory indexes (NLR, MLR, PLR, NLPR, SII, SIRI, AISI) were derived from baseline CBC tests.
Based on the diagnostic tools and criteria1,2,14,21, cases diagnosed with lumbar brucella spondylodiscitis or lumbar type 1 MCs in the past 5 years and who had simultaneously lumbar MRI, Complete Blood Count (CBC) test, C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR) results, and aged 18-65 years were selected to yield a study population. On the other hand, cases with inadequate data, aged <18 or >64 years, other infectious spondylodiscitis types than brucella, other MCs types than type 1, and other non-infectious conditions such as rheumatic spondylodiscitis (ankylosing spondylitis or Andersson lesion) were excluded from the study. Also, previous or recurrent brucella spondylodiscitis, involved other spinal levels than the lumbar spine were exclusion causes.
The two groups were statistically assessed and compared for baseline features such as age, gender, symptom duration, CRP, ESR, CBC values, and indexes derived from the CBC.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Considering their promising roles, we hypothesized that hematological inflammatory indices may have a distinctive value between brucella spondylodiscitis and type 1 Modic Changes (MCs). If the hypothesis is valid, early diagnosis-differential diagnosis-treatment processes may become easier and more successful. Given that hematological inflammatory indices are faster, practical, simpler, inexpensive, and easily accessible indicators, they may be more appropriate tools in differentiation between brucella spondylodiscitis and type 1 MCs.

Questions about this trial
What is this clinical trial studying?
An observational study of Brucella Spondylitis, run by Yuzuncu Yil University at 1 site in Turkey (Türkiye).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 29 May 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
C-Reactive Protein (CRP) (time frame: Baseline). The study lists 9 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 May 2024; AzTrials last refreshed its copy on 6 Nov 2026.
