title: Important complications of chronic kidney disease.
abstract: The complications of chronic kidney disease (CKD) are dyslipidaemia, hyperkalaemia, metabolic acidosis, anaemia, and bone and mineraldisorders. Dyslipidaemia may be treated with low-density lipoprotein-lowering agents. Statins are ineffective in stages 4 and 5 CKD, but areindicated for preventing the progression of disease in the earlier stages. Chronic acidosis has recently been shown to be a risk factor in theprogression of CKD renal dysfunction. Therefore, treatment is mandatory. Practically, this should consist of 1 - 2 heaped teaspoons of sodiumbicarbonate 2 - 3 times per day, which is an inexpensive and safe therapy that does not raise the blood pressure in spite of the increased sodiumlevel. Target levels of haemoglobin, according to international guidelines, are between 10 g/dL and 12 g/dL. The serum phosphate level is raisedin stage 4 CKD, and especially in stage 5 CKD, which is associated with coronary carotid and other vascular calcifications and may result inischaemic heart disease, myocardial infarction and stroke. A raised parathyroid hormone level (secondary hyperparathyroidism) is also a majorrisk factor for cardiovascular disease and is associated with increased hypertension and resistance to the treatment of CKD-associated anaemia.
