Salivary Creatinine Estimation as an Alternative to Serum Creatinine in Patients with Obstetric Related Acute Kidney Disease

Dr. Arun Kumar Jha, Dr. Ela Jha, Dr. Annie Samuel

Abstract: Introduction- Obstetric related acute kidney disease (ORAKD) contributes significantly to maternal & foetal morbidity & mortality. Its incidence is 3-7 % of overall cases of acute kidney injury (AKI) in India. It is most commonly observed in the post partum period & followed by cases seen in third trimester. Sepsis, preeclampsia & eclampsia are the leading causes of ORAKD in developing countries, while in developed countries, chronic hypertension & renal pathologies are the main causes. This clinical entity requires frequent serum analysis for diagnosis & monitoring of clinical outcomes & for evaluation of prognosis. Serum creatinine is considered as a gold standard renal function test in ORAKD. Blood sampling for estimation of S. creatinine is an invasive procedure, in contrast to its estimation from salivary assays which is a non invasive, simple, & cost effective procedure. Salivary creatinine evaluation is very helpful in patients suffering from clotting disorders like haemophilia & when venous access is compromised. The values of salivary creatinine show a positive correlation with values of serum creatinine. Aim 1. To establish a correlation between serum & salivary creatinine levels.2. To evaluate the role of salivary creatinine as an alternative modality of diagnosis & management in ORAKD. Methodology A prospective observational study was conducted on 200 women in the age group of 20-40 years, in the third trimester of pregnancy, in the Department of Obstetrics & Gynaecology, MGM MCH. The cases were divided into two groups. Group I consisted of 100 cases of ORAKD as a result of various etiologies such as PIH, preeclampsia, eclampsia & sepsis. Group II consisted of 100 cases which served as healthy control group. The study was carried out for a period of one year from May 2017 & the subjects were followed until delivery & upto 6 weeks post partum. Cases & controls were compared on various parameters & the results statistically analysed. Results Serum & salivary creatinine showed a positive correlation in cases of ORAKD (group I) r=0.832. In the control group II, a negative correlation was found in serum & salivary creatinine levels r= -0.321. Conclusion Salivary creatinine estimation can be employed as an alternative diagnostic modality to serum creatinine estimation in ORAKD cases.
