Insights

Rifampicin resistance (RR) in tuberculosis (TB) is a marker for multidrug-resistant TB (MDR-TB). This case highlights a rare pediatric RR-TB in Nigeria, emphasizing challenges in management and parental compliance.

Area of Science:

  • Microbiology
  • Pediatrics
  • Infectious Diseases

Background:

  • Antituberculous drug resistance complicates Mycobacterium tuberculosis (TB) management.
  • Rifampicin resistance (RR) often indicates multidrug-resistant TB (MDR-TB), posing significant treatment challenges.
  • Pediatric RR/MDR-TB is infrequently reported, especially in regions like Nigeria.

Observation:

  • A 2-year-old Nigerian girl presented with prolonged fever, cough, dyspnea, and weight loss.
  • Diagnostic workup, including GeneXpert MTB/RIF on gastric washout, confirmed RR-TB.
  • No known TB contact or prior treatment history was reported for the patient or her parents.

Findings:

  • The case represents a rare instance of pediatric RR-TB diagnosed in the hospital.
  • GeneXpert MTB/RIF confirmed rifampicin resistance, a surrogate for MDR-TB.
  • The patient's parents declined TB screening and follow-up treatment referral.

Implications:

  • Young children are vulnerable to developing complex drug-resistant TB.
  • Management of pediatric RR/MDR-TB requires specialized care, longer treatment, and addresses potential toxicity.
  • Poor parental compliance presents a significant barrier to successful treatment outcomes in pediatric drug-resistant TB cases.

Pulmonary Tuberculosis I

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Pulmonary Tuberculosis III

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:
Pulmonary Tuberculosis IV01:26

Pulmonary Tuberculosis IV

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Pulmonary Tuberculosis V

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...
Rocky Mountain Spotted Fever01:26

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
Clinical Significance of Antibiotic Resistance01:25

Clinical Significance of Antibiotic Resistance

Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...
