ICD-10: G62.0

Drug-induced polyneuropathy (DIPN), classified under ICD-10 code G62.0, is a condition characterized by peripheral nerve damage resulting from exposure to certain medications. Understanding its clinical presentation, signs, symptoms, and patient characteristics is crucial for effective diagnosis and management.

Clinical Presentation

Overview

DIPN typically manifests as a combination of sensory, motor, and autonomic symptoms, which can vary significantly among patients depending on the specific drug involved and individual susceptibility. The onset of symptoms may occur shortly after the initiation of the offending medication or may develop over a longer period, often persisting even after the drug is discontinued.

Commonly Affected Drugs

Several classes of medications are known to cause polyneuropathy, including:
- Chemotherapeutic agents: Such as vincristine and cisplatin, which are frequently associated with chemotherapy-induced peripheral neuropathy (CIPN) [1].
- Antiretroviral drugs: Particularly those used in HIV treatment, like stavudine and didanosine [2].
- Antibiotics: Such as metronidazole and isoniazid, which can lead to nerve damage [3].
- Others: Including certain anticonvulsants and heavy metals.

Signs and Symptoms

Sensory Symptoms

• Numbness and Tingling: Patients often report a "pins and needles" sensation, particularly in the hands and feet.
• Pain: This can range from mild discomfort to severe burning or stabbing pain, often exacerbated at night.
• Loss of Sensation: Patients may experience decreased ability to feel touch, temperature, or pain, leading to an increased risk of injuries.

Motor Symptoms

• Weakness: Muscle weakness may occur, particularly in the distal muscles, leading to difficulty with fine motor tasks.
• Atrophy: Prolonged nerve damage can result in muscle wasting due to disuse.

Autonomic Symptoms

• Orthostatic Hypotension: Patients may experience dizziness or fainting upon standing due to blood pressure regulation issues.
• Gastrointestinal Symptoms: Such as constipation or diarrhea, can occur due to autonomic nerve involvement.

Other Symptoms

• Balance Issues: Difficulty maintaining balance and coordination, increasing the risk of falls.
• Temperature Sensitivity: Patients may have an altered perception of temperature, feeling excessively hot or cold.

Patient Characteristics

Demographics

• Age: Older adults are often more susceptible to DIPN due to age-related changes in drug metabolism and increased polypharmacy.
• Gender: Some studies suggest a higher prevalence in females, potentially due to differences in drug metabolism and hormonal factors [4].

Comorbidities

• Diabetes Mellitus: Patients with diabetes may have pre-existing neuropathy, making them more vulnerable to drug-induced exacerbations.
• Renal Impairment: Reduced kidney function can affect drug clearance, increasing the risk of toxicity and subsequent neuropathy.

Genetic Factors

• Genetic Predisposition: Certain genetic polymorphisms may influence individual susceptibility to drug-induced nerve damage, particularly in the context of chemotherapy [5].

Conclusion

Drug-induced polyneuropathy (ICD-10 code G62.0) presents a complex clinical picture characterized by a range of sensory, motor, and autonomic symptoms. Recognizing the signs and symptoms, along with understanding patient characteristics, is essential for timely diagnosis and management. Clinicians should maintain a high index of suspicion, especially in patients receiving medications known to cause neuropathy, and consider regular monitoring for early detection and intervention.

By being aware of the potential for DIPN, healthcare providers can better manage treatment plans and mitigate the risks associated with drug therapy.
