Importance of red blood cell distribution width (RDW) in patients with upper gastrointestinal haemorrhage

To explore the effect of red blood cell distribution width levels on the diagnosis and management of upper gastrointestinal haemorrhage.

The retrospective study was conducted at Ankara Numune Education and Research Hospital, Turkey, and comprised record of patients diagnosed with upper gastrointestinal haemorrhage from January 1, 2013, to December 31, 2013. Factors analysed were age, gender, red blood cell distribution width level, admission haemoglobin and haematocrit levels, endoscopy findings classified according to the Forrest system, comorbid diseases, use of medications, unhealthy habits like alcohol usage and smoking, and mortality rate.

Of the 147 patients, 93(64%) were men. The overall median age of the sample was 60 years. Besides, 117(79.6%) patients had comorbid diseases, of which hypertension 56(38.4%) was the most common. A total of 24(16.8%) patients were using antiplatelet or anticoagulant drugs, while 30(20.5%) were on non-steroidal anti-inflammatory drugs. Peptic ulcer in 128(87.1%) patients was the most common cause of haemorrhage. The median red blood cell distribution width level of the study population was 15.25% which was significantly higher compared to the reference values (p<0.05).. In contrast, haemoglobin 9.55% (3.7) and haematocrit 28.75% (10.8)were significantly lower (p<0.05). Mortality rates were significantly higher in patients with higher red blood cell distribution width values (p<0.05).

Red blood cell distribution width levels were higher during the acute phase of upper gastrointestinal haemorrhage.
