Insights

Q fever, a Coxiella burnetii infection, can cause severe chronic illness. Early diagnosis and treatment in kidney transplant recipients are crucial for managing this high-morbidity disease.

Area of Science:

  • Infectious Diseases
  • Nephrology
  • Transplantation

Background:

  • Q fever is a zoonotic infection caused by Coxiella burnetii, presenting with diverse acute and chronic symptoms.
  • Chronic Q fever is linked to specific risk factors including vascular prosthesis, pregnancy, immunosuppression, and advanced chronic kidney disease.

Observation:

  • A kidney transplant recipient experienced prolonged fever, anemia, and elevated inflammatory markers (ESR, CRP) with negative blood cultures.
  • Serological tests indicated chronic Q fever, leading to a probable diagnosis based on Dutch Fever Consensus Group Guidelines.

Findings:

  • The patient was diagnosed with probable chronic Q fever.
  • Treatment with doxycycline and hydroxychloroquine achieved clinical remission.

Implications:

  • This case highlights the importance of considering chronic Q fever in immunocompromised patients, particularly kidney transplant recipients, presenting with unexplained fever.
  • Prompt diagnosis and treatment are essential to prevent severe morbidity and mortality associated with chronic Q fever.

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 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...

Kidney Transplant I: Introduction

A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living donor...

Kidney Transplant III: Nursing Management

Postoperative Nursing Management for Kidney Transplant PatientsPostoperative nursing management care includes monitoring the surgical site, encouraging early movement, and promoting lung health through breathing exercises. Nurses also administer prescribed medications like H2-blockers, such as famotidine, or proton pump inhibitors, like omeprazole, to help prevent gastrointestinal ulcers and bleeding. Fungal infections in the mouth and bladder can result from immunosuppressive and antibiotic...

Chronic Kidney Disease IV: Nursing Management

Nursing management is essential for preventing complications, maintaining stability, and improving patients' quality of life in chronic kidney disease (CKD). By using a structured approach, nurses help slow CKD progression and support effective patient care​.1. Comprehensive patient assessmentEffective management begins with nurses reviewing the patient’s medical history, and identifying key risk factors like diabetes, hypertension, and nephrotoxic drug use. Nurses assess signs of fluid...
