ALB and Hypoalbuminemia: Although the precise mechanisms have not been fully described, serum albumin has protective effects such as antioxidant activity, maintenance of physiologic homeostasis, and anti-inflammatory effects.[32,33] Therefore, these protective biologic functions may be impaired in conditions of hypoalbuminaemia, and therefore, increased morbidity and mortality can consequently develop in severely septic patients.[34] This theory is consistent with our study findings since the levels of albumin on admission were significantly lower in patients with urosepsis than in those with fUTI.
