Abstract

Purpose: Nutrition is severely impaired in individuals with renal impairment, and transplant often ameliorates this condition. In this study, we aimed to evaluate the controlling nutritional status (CONUT) score of kidney transplant (KT) recipients.
Materials and methods: Using the data from the nephrology transplant unit, we analyzed 188 patients whose data on the constituents of the CONUT score were available. We included KT individuals with at least one lymphocyte count and total cholesterol and albumin concentrations. This data has been used to calculate the CONUT score. The decrease of lymphocyte counts, and total cholesterol was determined with 0, 1, 2, and 3 points, and the reduction of albumin was assigned with 0, 2, 4, and 6 points in agreement with disease severity. Patients were classified according to this score: normal, light, moderate, and severe.
Results: There were 130 patients in normal, 54 in light, and three in moderate and one in severe group. The CONUT score was good for regular-weight patients both before and after transplantation. All laboratory findings revealed significant differences between CONUT groups (p<0.05).
Conclusion: After transplantation, the number of patients in the underweight group decreased when normal weight and obesity increased. However, some patients’ nutrition was not ameliorated. The CONUT score may be a useful tool for monitoring transplant patients’ nutritional status.

Böbrek transplantli bireylerde beslenme takibi için CONUT skoru

Abstract

Amaç: Kronik böbrek hastalığı hastanın nutrisyonel durumunu bozmaktadır. Nakil bu tabloyu sıklıkla düzeltir. Çalışmamızda böbrek transplantı olan bireylerde nutrisyonel durumu değerlendirmek için kontrol beslenme durumu (CONUT) skorunu değerlendirmeyi amaçladık.
Gereç ve yöntem: Böbrek nakli olan bireyleri takip eden Nefroloji bilim dalından gelen verileri kullanarak, 188 bireyin CONUT skorunu hesaplamayı amaçladık. Laboratuvar bilgi sisteminde en az bir kez ölçülmüş, lenfosit sayısı, total kolesterol ve albümin düzeyleri olan nakilli bireylerini dahil ettik. Lenfosit sayısı ve toplam kolesteroldeki azalma 0, 1, 2 ve 3 puanla, albümin azalması ise hastalığın şiddetine göre 0, 2, 4 ve 6 puanla belirlendi. Hastalar bu skora göre normal, hafif, orta ve ağır olarak sınıflandırıldı.
Bulgular: Normal grupta 130, hafif grupta 54, orta grupta 3 ve ağır grupta bir hasta vardı. CONUT skoru normal kilolu hastalar için hem nakil öncesinde hem de sonrasında iyiydi. Tüm laboratuvar bulguları CONUT grupları arasında anlamlı fark olduğunu ortaya koydu (p<0,05).
Sonuç: Transplantasyon sonrası normal kilolu ve obez birey sayısı artarken, az kilolu hasta sayısı azaldı. CONUT skoru transplante hastaların beslenme durumunu izlemede etkin bir araç olarak öne sürülebilir.
