Could the C-reactive protein/albumin Ratio Predict Mortality in Patients with Common Variable İmmunodeficiency?

Öz

Common variable immunodeficiency (CVID) is the most common symptomatic immunodeficiency in adults. This study assessed the utility of using the C-reactive protein (CRP)/albumin ratio (CAR) at diagnosis to predict mortality in CVID patients. Between 2010 and 2022, hospital records and follow-up cards of patients with CVID were reviewed retrospectively. Seventy-five patients were included in the study. CRP 0–5 mg/L and albumin 3.5–5.5 g/dL were taken as references. The CAR was obtained by dividing the CRP value by the albumin value. Of the included patients, 41 (55%) were male and 34 (35%) were female. The median age was 38 (21–77) years. The mortality rate of the patients during the follow-up time was 20%. Of the patients, 41% had splenomegaly, 10.6% had malignancy, and 39% had bronchiectasis. The cut-off value of CAR to predict mortality was >2.18 (sensitivity: 88.4%, specificity: 90.1%). When the patients were classified according to the CAR, the mortality rate in the patient group with a CAR > 2.18 was statistically significantly higher than the patient group with a CAR ≤ 2.18. The CAR is a cheap, simple, and easily calculated parameter that can predict mortality in CVID patients.

C-reaktif protein/albümin Oranı Yaygın Değişken İmmün Yetmezliği Olan Hastalarda Mortaliteyi Tahmin Edebilir mi?

Yaygın değişken immün yetersizlik (YDİY), yetişkinlerde en sık görülen semptomatik primer immün yetmezliktir. Bu çalışma, CVID hastalarında mortaliteyi tahmin etmek için tanıda C-reaktif protein (CRP)/albümin oranı (CAO) kullanmanın faydasını değerlendirdi. 2010-2022 yılları arasında YDİY'li hastaların hastane kayıtları ve takip kartları retrospektif olarak incelendi. Çalışmaya yetmiş beş hasta dahil edildi. CRP 0–5 mg/L ve albümin 3,5–5,5 g/dL referans olarak alındı. CAO, CRP değerinin albümin değerine bölünmesiyle elde edildi. Çalışmaya alınan hastaların 41'i (%55) erkek, 34'ü (%35) kadındı. Ortanca yaş 38 (21-77) idi. Takip süresi boyunca hastaların ölüm oranı %20 idi. Hastaların %41'inde splenomegali, %10.6'sında malignite ve %39'unda bronşektazi vardı. CAO'nın mortaliteyi öngörmek için kesme değeri >2,18 idi (duyarlılık: %88,4, özgüllük: %90,1). Hastalar CAO göre sınıflandırıldığında, CAO > 2,18 olan hasta grubunda mortalite oranı, CAO ≤ 2,18 olan hasta grubuna göre istatistiksel olarak anlamlı derecede yüksekti. CAO, YDİY hastalarda mortaliteyi tahmin edebilen ucuz, basit ve kolayca hesaplanabilen bir parametredir.
