Insights
Nirmatrelvir/ritonavir (N/R) shows promise for treating COVID-19 in hemodialysis patients. This small study found symptom improvement and viral load reduction with manageable side effects after dosage adjustments.
Area of Science:
- Infectious Diseases
- Nephrology
- Pharmacology
Background:
- Patients on hemodialysis (HD) face higher risks for severe COVID-19.
- Limited clinical trial data exist for nirmatrelvir/ritonavir (N/R) in HD populations.
Observation:
- N/R was administered to four HD patients with COVID-19 under informed consent.
- Clinical symptoms improved around day 3 post-administration.
- Viral load reduction was observed approximately 10 days after N/R initiation.
Findings:
- Nirmatrelvir/ritonavir demonstrated clinical improvement and viral load reduction in HD patients with COVID-19.
- Common adverse effects included nausea and vomiting.
- Dosage adjustments improved tolerance without compromising efficacy.
Implications:
- Nirmatrelvir/ritonavir may be an effective treatment option for COVID-19 in hemodialysis patients.
- Further research is warranted to confirm N/R efficacy and safety in this vulnerable group.
- This study highlights the potential for therapeutic interventions in underrepresented patient populations.
Abstract:
Patients undergoing hemodialysis (HD) are particularly vulnerable to coronavirus disease 2019 (COVID-19) and are at increased risk of developing severe infection. However, given the exclusion of such patients from clinical trials, there are limited data regarding the effectiveness of the antiviral drug nirmatrelvir/ritonavir (N/R) in patients on HD. We prescribed N/R to 4 patients on HD with COVID-19 after obtaining informed consent. Their clinical symptoms were improved at approximately 3 days after N/R administration. The viral load was reduced after approximately 10 days. The main adverse effects were nausea and vomiting. Rational dosage adjustment obtained good tolerance but did not influence the efficacy. These results suggest that N/R may be a promising agent for patients on HD with COVID-19.

Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...
