The reason behind the failure of Nikoleta's anaemia was due to an inherited genetic condition referred to as "Beta-thalassemia".
In this condition, there's the absence of a beta haemoglobin chain affecting the oxygen-carrying capacity of the body tissue.
Treating the patient with iron will not suffice for the condition as there's adequate iron but haemoglobin possesses a defect.
