Clinical significance of urinary human tissue non-specific alkaline phosphatase (hTNAP) in pre-eclampsia and eclampsia.
The aim of this work was to determine the levels of urinary human tissue non-specific alkaline phosphatase (hTNAP) in pre-eclampsia and eclampsia in order to assess renal tubular damage. Urine samples were collected from 26 mild pre-eclamptic, 26 were pre-eclamptic, 20 eclamptic patients and 20 healthy pregnant women (controls) in their late third trimester. Urinary hTNAP/creatinine (hTNAP/cr) in severe pre-eclampsia and eclampsia were significantly higher than in controls. Urinary hTNAP/cr was increased in 23%, 77% and 90% of cases of mild pre-eclampsia, severe pre-eclampsia and eclampsia, respectively, indicating that the increase correlates with the severity of the disease. Marked elevation or urinary hTNAP/cr was also associated with bad fetal outcome. These results provide additional evidence for renal tubular damage in pre-eclampsia and eclampsia.
