Abstract

Insights

Puumala virus infection, also known as nephropathia epidemica, can cause acute renal failure in young adults. Early consideration of hantavirus infection is crucial for diagnosis and management.

Area of Science:

  • Infectious Diseases
  • Nephrology
  • Virology

Background:

  • Puumala virus infection (nephropathia epidemica) is a significant cause of acute kidney injury.
  • Hantavirus infections are endemic in parts of Central Europe.

Observation:

  • A 34-year-old patient presented with fever, headache, abdominal pain, and acute renal failure.
  • Initial investigations revealed thrombocytopenia, elevated CRP, proteinuria, glucosuria, and erythrocyturia.
  • Renal biopsy confirmed acute hemorrhagic interstitial nephritis.

Findings:

  • Diagnosis of nephropathia epidemica was confirmed by Puumala virus IgM and IgG antibodies.
  • The patient experienced severe acute kidney injury with peak creatinine of 640 µmol/l and urea of 30.5 mmol/l.
  • The patient recovered fully within 2 years without specific antiviral therapy.

Implications:

  • Hantavirus infection should be considered in the differential diagnosis of acute renal failure in young patients presenting with similar symptoms in Central Europe.
  • Prompt diagnosis can guide clinical management and potentially prevent complications.
  • Further research into Puumala virus pathogenesis and treatment is warranted.

Acute Pyelonephritis II: Diagnostic Studies and Management

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Acute Pyelonephritis I: Introduction

Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such as Proteus,...

Acute 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...

Dialysis

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...
Poliomyelitis01:17

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...

Acute 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...
