Abstract

Bu çalışmanın amacı Ailevi Akdeniz Ateşi (FMF) olan hastalarda ataksız dönemde serum amiloid A (SAA) ile klinik pratikte sık kullanılan diğer inflamatuar belirteçler arasındaki ilişkinin değerlendirilmesidir.Bu çalışmaya FMF tanısı olan 90 hasta (38 erkek, 52 kadın) dahil edildi. FMF tanısı Tel-Hashomer kriterlerine göre konuldu. Hastalar SAA düzeyine göre iki gruba ayrıldı. Grup 1: yüksek SAA (>6.4 mg/dL), Grup 2: normal SAA (≤6.4 mg/dL). Gruplarda SAA düzeyleri ile diğer inflamatuar belirteçler arasındaki korelasyon değerlendirildi. Çalışamaya dahil edilen 90 hastanın %56.7’sinin SAA değeri >6.4 mg/dL ve %43.3’ünün ≤6.4 mg/dL’ydi. Grupların serum kreatinin, tahmini glomerüler filtrasyon hızı, ürik asit, albumin, lökosit, lenfosit ve platelet sayısı ile Platelet/Lenfosit oranı (PLO) açısından anlamlı farklılık gözlenmedi. Grup 1’in ortalama fibrinojen, C-reaktif protein (CRP), eritrosit sedimentasyon hızı (ESH), Nötrofil/Lenfosit oranın (NLO) ve CRP/albümin değerleri grup 2’den istatistiksel olarak daha yüksek ve hemoglobin ortalaması ise daha düşük saptandı. Grup 1’in ortalama nötrofil ve monosit sayısı grup 2’den daha yüksekti ancak bu fark istatistiksel açıdan anlamlı değildi. SAA ile CRP arasında pozitif yönde güçlü, ESH ve CRP/albümin ile pozitif yönde orta, ve lökosit sayısı ve NLO arasında pozitif yönde zayıf bir korelasyon saptandı. CRP düzeyi FMF hastalarında ataksız dönemde SAA ile en yüksek korelasyonu göstermesi nedeniyle SAA düzeylerinin değerlendirilemediği durumlarda hastalık aktivitesi ve subklinik inflamasyonu öngörmek için kullanılabilir

Correlation of Serum Amyloid A in the Attack-Free Period with Other Inflammatory Markers in Adult Familial Mediterranean Fever Patients

Abstract

The aim of this study is to evaluate the relationship between serum amyloid A (SAA) and other inflammatory markers frequently used in clinical practice in patients with Familial Mediterranean Fever (FMF).Ninety patients (38 males, 52 females) with a diagnosis of FMF were included in this study. FMF diagnosis was made according to Tel-Hashomer criteria. The patients were divided into two groups according to their SAA levels. Group 1:high SAA (>6.4 mg/dL), Group 2:normal SAA (≤6.4 mg/dL). The correlation between SAA levels and other inflammatory markers in the groups was evaluated.Of the 90 patients included in the study, 56.7% had SAA value>6.4 mg / dL and 43.3% had ≤6.4 mg/dL. There was no significant difference between the groups in terms of serum creatinine, estimated glomerular filtration rate, uric acid, albumin, leukocyte, lymphocyte and platelet counts and platelet/lymphocyte ratio (PLR). The average fibrinogen, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), neutrophil/lymphocyte ratio (NLR) and CRP/albumin values in group 1 were statistically higher than group 2, and the mean hemoglobin was lower. The mean neutrophil and monocyte count of group 1 was higher than group 2, but this difference was not statistically significant. There was a strong positive correlation between SAA and CRP, moderate positively with ESR and CRP/albumin, and a weak positive correlation between leukocyte count and NLR.Since the CRP level shows the highest correlation with SAA during the attack-free period in FMF patients, it can be used to predict disease activity and subclinical inflammation in cases where SAA levels cannot be evaluated.
