Description of Pre-Hemodialysis Serum Phosphate in Late-Stage Kidney Disease Patients of Productive Age (15-64 Years) at the Indonesian Christian University General Hospital

Abstract

In Indonesia, end-stage kidney disease is still a health problem that needs attention. End-stage kidney disease or abbreviated as PGTA reflects the fifth stage of chronic kidney disease, at this stage, there is a buildup of toxins, fluids, electrolytes, and the remains of the body's metabolism. In stage 5 chronic kidney disease, the glomerular filtration rate decreases < 15 ml/minute / 1.73 m2 and has occurred for 3 months or more. One of the clinical complications of end-stage renal disease is an increase in phosphate levels in the patient's blood serum (hyperphosphatemia), this occurs due to disruption of the kidney's phosphate excretion function. Hyperphosphatemia in PGTA patients can result in hyperparathyroidism, soft tissue, and cardiovascular calcification, and affect bone mineral disorders. In kidney disease patients with a glomerular filtration rate < 30 ml/minute / 1.73m2, the prevalence of hyperphosphatemia complications increased to 23%. This study aims to determine the description of pre-hemodialysis inorganic phosphate levels in the serum of PGTA patients of productive age (15-64 years) undergoing hemodialysis at the Indonesian Christian University General Hospital for the period January 2022. The research conducted was a descriptive study, to determine the description of phosphate levels serum of PGTA patients. The data used in this study is primary data by directly taking the blood of 20 pre-hemodialysis patients with end-stage kidney disease and then examining it in the laboratory. In this study, the results showed that 10 PGTA patients (50%) experienced an increase in serum inorganic phosphate levels above normal (>5 mg/dl). Meanwhile, 9 people (45%) had normal serum phosphate levels (2.5 - 5 mg/dl), and 1 other person had below normal serum phosphate levels (<2.5 mg/dl).
