Abstract

Insights

Drug-induced fever from rifampicin is rare but possible. Discontinuing the antibiotic rapidly resolved fever in two patients, highlighting the need for careful diagnosis in persistent fever cases.

Area of Science:

  • Infectious Diseases
  • Pharmacology
  • Rheumatology

Background:

  • Drug-induced fever is an uncommon adverse effect of antibiotics.
  • Rifampicin is a key antibiotic used in treating periprosthetic joint infections.

Purpose of the Study:

  • To report two cases of suspected rifampicin-induced fever.
  • To emphasize the diagnostic considerations for drug-induced fever in patients with periprosthetic joint infections.

Main Methods:

  • Case report methodology.
  • Clinical observation of two patients treated for periprosthetic joint infection with rifampicin.
  • Monitoring of symptoms and response to antibiotic discontinuation.

Main Results:

  • Two patients developed persistent fever despite clinical improvement during rifampicin treatment for periprosthetic joint infection.
  • Absence of typical infectious or inflammatory symptoms was noted.
  • Discontinuation of rifampicin resulted in rapid resolution of fever in both cases.

Conclusions:

  • Drug-induced fever should be suspected in cases of persistent fever without clear infectious signs, especially during antibiotic therapy.
  • Prompt identification and cessation of the offending drug, like rifampicin, can lead to swift recovery.
  • Considering drug-induced fever can prevent unnecessary investigations and interventions.

Increased Body Temperature

A body temperature above  38°C  (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

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...

Endocarditis IV: Nursing Management

Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...

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...

Infective endocarditis management involves a multifaceted approach encompassing infection prevention, lifestyle modifications, pharmacological therapy, and surgical management.Infection Prevention:Hand Hygiene: Thorough handwashing is crucial to prevent the spread of infection. Hand hygiene should be performed regularly, especially before and after using the restroom.Oral Hygiene: Good oral hygiene is essential. It includes brushing teeth immediately after waking up and before bed, flossing...
