Acute Renal Failure and HELLP Syndrome: A Single Center's Experience
1Department of Nephrology, King Fahd Hospital, Jeddah Kidney Center, Jeddah, Saudi Arabia.
Summary
This study identifies a rare condition of hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome presenting as acute renal failure. Early recognition is crucial for accurate diagnosis and good prognosis in patients surviving the acute phase.
Area of Science:
- Nephrology
- Obstetrics
- Hematology
Background:
- Acute renal failure (ARF) is a significant complication in obstetric and gynecologic patients.
- Distinguishing ARF causes is critical for appropriate management and patient outcomes.
- HELLP syndrome is a severe condition that can mimic other thrombotic microangiopathies.
Purpose of the Study:
- To report on patients presenting with acute renal failure and HELLP syndrome.
- To highlight the diagnostic challenges and potential for misdiagnosis.
- To emphasize the importance of recognizing HELLP syndrome in ARF.
Main Methods:
- Retrospective review of 52 patients with ARF referred to a specialized center.
- Identification of patients with concurrent HELLP syndrome.
- Renal biopsy analysis in six patients to determine the histopathological cause of ARF.
Main Results:
- Seven out of 52 patients (13.5%) presented with ARF and HELLP syndrome.
- Common misdiagnoses included hemolytic uremic syndrome and idiopathic thrombotic thrombocytopenic purpura.
- Renal biopsy findings revealed acute tubular necrosis in four patients and acute cortical necrosis in one.
Conclusions:
- HELLP syndrome can present as ARF and is easily misdiagnosed.
- Familiarity with HELLP syndrome is essential for correct diagnosis in renal failure patients.
- Prognosis is favorable for patients who survive the acute stage of HELLP-associated ARF.

01:22Acute Kidney Injury I: Introduction
Introduction:Acute Kidney Injury (AKI) describes a swift decrease in kidney function occurring over hours to days, characterized by the kidneys' failure to remove waste products from the bloodstream. This leads to dangerous complications like metabolic acidosis, fluid overload, and electrolyte imbalances, such as hyperkalemia, which can cause life-threatening arrhythmias. AKI is common in both hospital and outpatient settings, often triggered by dehydration, sepsis, or exposure to nephrotoxic...
01:27Dialysis
Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

01:29Acute Kidney Injury III: Clinical Manifestations
Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...
01:20Acute Kidney Injury V: Interprofessional Care
Acute Kidney Injury (AKI) requires a collaborative healthcare approach to restore renal function and prevent complications. Essential management strategies involve monitoring fluid and electrolyte balance, adjusting medications, initiating dialysis when necessary, and providing nutritional support.Fluid and Electrolyte ManagementFluid Monitoring: Regularly monitoring body weight, central venous pressure, and urine output helps detect fluid imbalances early. Patient intake and output are...
01:29Acute Kidney Injury II: Pathophysiology
Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...
01:30Acute Kidney Injury IV: Diagnostic Studies and Prevention
Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...
