Z16.31
Resistance to antiparasitic drug(s)
Clinical Classification Guidelines
Inclusion Terms
- Resistance to quinine and related compounds
Medical Intelligence & Overview
ICD-10 code Z16.31 refers to resistance to antiparasitic drugs, specifically highlighting cases where parasites have developed resistance to quinine and similar medications. This condition can complicate the treatment of parasitic infections, making management more challenging and requiring alternative strategies. Recognizing this resistance is vital for healthcare professionals to adapt treatment plans effectively and ensure successful outcomes.
Causes & Symptoms
Clinical Causes: Repeated or improper use of antiparasitic medications, leading to selection pressure favoring resistant strains. Inadequate dosing or incomplete treatment courses, allowing resistant parasites to survive and proliferate. Genetic mutations in parasites that confer resistance to specific drugs, such as quinine and related compounds. Transmission of resistant parasite strains through vector populations, perpetuating resistance within communities. Use of counterfeit or substandard medications containing insufficient active ingredients. Incomplete eradication of parasites due to pharmacokinetic factors like poor drug absorption or metabolism.
Key Symptoms: Persistence or recurrence of parasitic infection symptoms despite treatment. Signs and symptoms specific to the parasitic disease involved, which might include fever, chills, or gastrointestinal issues. Possibility of increased severity or duration of symptoms in resistant cases. Lack of expected therapeutic response after standard medication courses. Potential for complications or secondary infections due to ongoing parasitic activity.
Diagnostic & Treatment
Diagnosis Path: monitor for persistent or recurrent infection symptoms despite appropriate treatment, which may suggest resistance.
Treatment Protocols: Enhancing infection control practices to prevent spread of resistant parasites in communities.
