The goal of the study was to measure and assess the c-reactive protein and uric acid levels in preeclampsia patients. In the study, serum samples from 30 participants—15 preeclampsia patients and 15 healthy pregnant women—were tested for levels of c-reactive protein and uric acid. The level of c-reactive protein was determined using an enzymatic technique. The findings demonstrated that, at p0.05, the c-reactive protein concentration was substantially higher in preeclampsia patients (4.770.9 mg/dl) than in healthy pregnant women (1.30.39 mg/dl). Additionally, at p 0.05, preeclampsia patients had significantly higher uric acid concentrations (8.973.35 mg/dl) than healthy pregnant women (3.60.5 mg/dl). These results suggest that preeclampsia is associated with elevated levels of c-reactive protein and uric acid. Consequently, it likely act as a biochemical marker for preeclampsia.

Preeclampsia is a medical disease in which pregnancy-related hypertension (blood pressure more than or equal to 110/90 mmHg) develops in conjunction with the presence of protein in the urine (proteinuria). Preeclampsia is a potentially catastrophic condition that puts both the mother and the fetus' lives in danger (Sibai et al, 2005).

Preeclampsia is a disorder unique to human pregnancy that manifests as substantial proteinuria and hypertension in a previously healthy woman on or after the 20th week of pregnancy. It affects 2-8% of pregnancies (Ghumiyyah and Sibai, 2012)

Early detection, careful monitoring, and treatment of preeclampsia by appropriate prenatal care are essential in preventing mortality related to preeclampsia. Intrauterine fetal growth retardation, low birth weight, fetal death, and neonatal death due to complications of preterm delivery are common parietal outcomes associated with preeclampsia. (Hoque et al. 2008)

Preeclampsia is linked to oedema, proteinuria, decreased renal function, maternal mortality, placental insufficiency, and intrauterine fetal growth retardation, according to Crook (2006). It is unclear how these risk factors and preeclampsia are related. The variations in risk between racial and ethnic groups point to a significant genetic component in the etiology of preeclampsia.

The acute phase protein known as C-reactive protein (CRP) is made by the liver and is present in the blood. Its level increases in response to a variety of inflammatory circumstances in the body since it is an acute phase protein (Pepys and Hirschfield, 2003). Women with preeclampsia have changed levels of inflammatory response mediators, such as C-reactive protein (Teran et al, 2001).

The last byproduct of purine metabolism is uric acid. Purines, such as adenosine guanine, are produced when nucleic acids break down (Ochei and kolhaktar,2008). The body's elevated uric acid concentration is known as hyperuricemia. In preeclampsia-related pregnancies, hyperuricemia is a frequent finding. According to Power et al. (2006), the clinical symptoms used to identify preeclampsia in women frequently come before proteinuria and hypertension. Uric acid in preeclampsia may have numerous causes, including accelerated tissue breakdown, acidosis, and increased activity of the enzyme xanthine oxidase/dehydrogenase (Johnson et al, 2003). Either a reduced or increased uric acid production has been implicated as the cause of hyperuricemia in preeclampsia. While altered tubular function and decreased uric acid clearance have both been observed, Fay (1990) postulated that the overproduction of uric acid may be due to increased purine breakdown in the placenta (Jeyabalan and Conrad,2007; Hill,1987; Fay,1990). Preeclampsia-related hyperuricemia is typically seen as a sign of renal impairment rather than a risk factor for the disease's progression.

Preeclampsia is a serious pregnancy condition that increases the risk of mortality and morbidity for both the mother and the fetus. Preeclampsia requires more study in order to enhance diagnosis, treatment, and prevention. Preeclampsia research has not been extensively conducted in Owerri, so the goal of this study is to assess the levels of C-reactive protein and uric acid in preeclampsia patients in Owerri, with the hope that the pattern of results will aid in preeclampsia clinical decision-making generally.

Study Area/Setting 

This study was carried out in Imo State University situated in Owerri metropolis; the capital city of Imo State located in the tropical rainforest of South-Eastern part of Nigeria. The major ethnic group is Igbo, with a few people from other tribe resident therein. The inhabitant are predominantly Christians with few muslims and pagans. Owerri is located within the South-East geopolitical zone of Nigeria and is situated on latitude 5o 271-5o 311N and longitude 6o 55-7o 031 E.

Study Population 

The study population consisted of 30 subjects attending antenatal clinic at the Federal Medical Centre Owerri, within the age of 25-40years. The 30 subjects were divided into two groups:

Group 1 are 15 pregnant women with preeclampsia 

Group 2 (control group) are 15 healthy pregnant women with normal blood pressure. 

Selection Criteria 

The subjects selected for the study were based on the following criteria:  Pregnant women with systolic blood pressure of 140mmHg or (Bp≥140/90mmHg) developed during pregnancy were selected for preeclampsia group (group 1). 

Healthy pregnant women with blood pressure were selected for group 2 (control group). 

Preeclampsia women and healthy pregnant women whose informed consent were obtained. 

Exclusive Criteria 

The following subjects were excluded from the sudy:

Preeclampsia patients who had Bp≥140mmHg before being pregnant. Preeclampsia patients with a history of diabetes, renal disease other cardiovascular illness and symptomatic diseases.

Preeclampsia patients with known systemic disease, as mentioned above. Preeclampsia patients whose informed consent could not be obtained because they were sceptical about the research work. 

All these were investigated during routine interviews and checked of medical records. 

Sample Collection 

In all subjects, about 5ml of venous blood were collected by venepunture technique from antecubital vein with 5ml disposable syringe. The whole blood samples were dispensed into centrifuge test tubes without anticoagulants and were immediately labelled for proper identification. The centrifuge test tubes containing the whole blood sample to clot. After that, the centrifuge test tubes were loaded in the centrifuge

and were spun at 10,000rpm for 10 minutes using wisperfuge model 1384 centrifuge (Samson Holland).  The supernatant serum was separated from the sedimented clotted  blood by using pasture pipette to collect the serum and transferred it into a sterile serum sample tube, which were again labelled for proper identification. The serum samples obtained were used for C-reactive protein estimation, and uric acid estimation. 

Laboratory Methods and Procedure 

The reagents used in the research work were of analytical grade. All the materials and reagents used were listed in the appendix 1. 

(a) Estimation of serum c-reactive protein(crp) by latex agglutination slide test using c-reactive protein reagent kit (agappe disnostics switzerland gmbh) 

 (b)  Estimated of   serum   uric  acid   by enzymatic spectrophotometric method using uric acid kit (biosystem reagents). 

Statistical Analysis 

All the values were expressed as mean ± standard deviation. The statistical analysis was carried out using student’s t-test to determine whether the difference between two groups is statistically significant or not when compared. Values with level of significance (p<0>

Table 1: Shows that the value of the maternal age of preeclampsia women 31.47 ±4.05years was not significantly different (p>0.05) when compared with the value of the maternal age of healthy pregnant women 31.13 ± 4.44years. This could be suggestive that age has no effect on preeclampsia.

As was expected, the values of the systolic blood pressure and diastolic blood pressure of preeclampsia women 147.67 ± 5.53mmHg and 95.07 ± 4.14mmHg respectively where significantly higher (p<0>
