Chronic kidney disease (CKD) is progressive loss of renal functions eventually requiring renal replacement therapy. It is a cause of major health concern, particularly because of the high morbidity and mortality rates it is associated with. It is defined as kidney damage or an estimated glomerular filtration rate (eGFR) < 60 ml/min per 1.73 m2, persisting for ≥ 3 months.1 The last few years have witnessed progressive increase in the burden of CKD, with its prevalence ranging from 13-16% in some of the developed countries and between 2-16% in the developing countries (Figure 1).
