Summary
Achromobacter denitrificans can cause kidney abscesses in immunocompetent individuals, often linked to kidney stones. This case highlights successful treatment with meropenem, marking the first reported instance of this specific infection.
Area of Science:
- Nephrology
- Infectious Diseases
- Microbiology
Background:
- Renal abscesses are uncommon, particularly in immunocompetent patients.
- Achromobacter species are emerging as opportunistic pathogens.
- Renal stones are a known risk factor for urinary tract infections and complications.
Observation:
- A 66-year-old immunocompetent male presented with a renal abscess.
- The abscess was associated with underlying renal lithiasis (kidney stones).
- The causative agent was identified as Achromobacter denitrificans.
Findings:
- This is the first reported case of a renal abscess caused by Achromobacter denitrificans.
- The patient received a 60-day course of meropenem (1g TID).
- Successful clinical and radiological resolution of the renal abscess was achieved.
Implications:
- Highlights Achromobacter denitrificans as a potential pathogen in renal infections.
- Suggests meropenem as an effective treatment option for Achromobacter denitrificans renal abscess.
- Underscores the importance of considering unusual bacteria in renal abscesses, especially in patients with risk factors like kidney stones.

01:27Acute 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,...
01:28Acute 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...
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...
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...
01:22Acute 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...
