Introduction

Hypertensive disorders during pregnancy represent a significant cause of maternal and fetal morbidity and mortality worldwide. In pregnant women, elevated blood pressure can indicate various underlying conditions, ranging from benign gestational hypertension to life-threatening pre-eclampsia or HELLP syndrome. Proper diagnosis and management are essential to ensure optimal outcomes for both mother and fetus. This paper presents a focused clinical assessment of Kita Brown, a 36-year-old G1 pregnant woman at 30 5/7 weeks gestation presenting with elevated blood pressure, discussing potential differential diagnoses, prioritizing the most urgent condition, recommending pertinent diagnostic tests, and outlining appropriate therapeutic interventions.

Case Summary

Kita Brown is a 36-year-old woman with an unremarkable pregnancy conceived via IVF, currently at 30 5/7 weeks gestation. She reports a recent elevated blood pressure reading, mild headache, and slight swelling. Her past medical history includes borderline hypertension managed with HCTZ before pregnancy. She was prescribed labetalol but did not adhere to the regimen. Her prenatal screening has remained normal, with no proteinuria detected initially or at third trimester screening. On presentation, her BP readings in the emergency setting are 166/88 mm Hg and 162/92 mm Hg, respectively. She denies additional symptoms such as visual changes, epigastric pain, or nausea.

Differential Diagnosis

Based on the clinical presentation, the primary differential diagnoses include:

1. Gestational Hypertension: This condition involves new-onset hypertension after 20 weeks gestation without proteinuria or other systemic features. It is common around this time and generally less severe but requires monitoring due to the risk of progression.
2. Preeclampsia: Characterized by hypertension with proteinuria or end-organ dysfunction after 20 weeks gestation. Although initial labs were normal, the current unrelieved hypertension and potential evolution necessitate considering preeclampsia.
3. Chronic Hypertension with Superimposed Preeclampsia: Pre-existing hypertension that has worsened or developed additional features such as proteinuria or other signs of end-organ damage during pregnancy, increasing maternal and fetal risk.

Most Important Diagnosis and First Priority

The most critical diagnosis to consider in Kita’s case is preeclampsia. This is because she now presents with sustained hypertension after 20 weeks gestation, and although she currently lacks overt symptoms such as visual disturbances or epigastric pain, the risk of progression to severe preeclampsia or eclampsia necessitates urgent evaluation.

The first priority in assessment is to determine whether preeclampsia has developed, especially given her elevated BP readings, even without current proteinuria evidence, because preeclampsia can present without initial proteinuria but may involve other signs of end-organ involvement such as elevated liver enzymes, thrombocytopenia, or renal impairment. Early identification is crucial to prevent progression and adverse maternal-fetal outcomes.

Diagnostic Tests

To confirm the diagnosis and assess disease severity, the following diagnostic tests are appropriate:

• Urinalysis with Protein Quantification: A 24-hour urine collection or spot protein-to-creatinine ratio to detect proteinuria, which is a hallmark of preeclampsia.
• Complete Blood Count (CBC): To evaluate for thrombocytopenia or hemolysis, which could indicate preeclampsia with severe features or HELLP syndrome.
• Serum Liver Function Tests (LFTs): To assess for elevated liver enzymes suggesting hepatic involvement.
• Serum Creatinine and BUN: To evaluate renal function, which may be compromised in preeclampsia.
• Uric Acid Levels: Elevated levels can support the diagnosis of preeclampsia.
• Fetal Monitoring: Non-stress testing or biophysical profile to assess fetal well-being, especially given the risk of intrauterine growth restriction.
• Blood Pressure Monitoring: Serial measurements to gauge control and progression.

Treatment Options and Rationales

Management will depend on the severity of her condition and gestational age.

1. Antihypertensive Therapy: Labetalol remains the first-line agent for pregnant women with hypertension; re-initiation or adjustment of medication is indicated. Given her non-adherence, reinstitution with close monitoring is paramount to prevent severe hypertension and complications such as stroke (American College of Obstetricians and Gynecologists, 2019).
2. Magnesium Sulfate: To prevent eclamptic seizures if signs of severe preeclampsia develop, particularly considering her blood pressure levels and potential for progression (ACOG, 2019).
3. Delivery Planning: Timing of delivery depends on maternal and fetal status. After 34 weeks, delivery is generally recommended for preeclampsia with features. At 30+ weeks, close fetal surveillance and corticosteroids for lung maturity are needed (Steege et al., 2018).
4. Fetal Surveillance: Frequent non-stress tests, biophysical profiles, or Doppler assessments to monitor fetal well-being, especially if preeclampsia progresses.
5. Patient Education: Emphasize importance of medication adherence, monitoring symptoms, and reporting any visual changes, epigastric pain, or decreased fetal movements.

Rationale for Approach

The focus on diagnosing preeclampsia early reflects its potential for rapid deterioration and severe maternal and fetal complications. Managing her hypertension with appropriate medications minimizes the risk of stroke and placental abruption. Confirming proteinuria or other signs of end-organ damage guides escalation of care and potential timing of delivery. Close fetal surveillance ensures timely intervention if the fetus shows signs of compromise. This comprehensive approach is aligned with current obstetric guidelines aimed at optimal outcomes (American College of Obstetricians and Gynecologists, 2019; Steege et al., 2018).

Conclusion

In summary, a pregnant woman at 30 weeks gestation presenting with elevated blood pressure requires prompt assessment to distinguish between gestational hypertension, preeclampsia, and chronic hypertension with superimposed features. The highest priority is to diagnose preeclampsia early to initiate appropriate management and delivery planning. Diagnostic tests aimed at identifying end-organ involvement guide treatment, which includes antihypertensives, seizure prophylaxis, and fetal surveillance. Timely intervention is critical to minimize risks of adverse outcomes to both mother and fetus.
