This systematic review found no significant association between chloroquine/hydroxychloroquine use and hearing disorders. Further research is needed due to very low certainty of evidence regarding auditory system side effects.
Area of Science:
- Pharmacology and Toxicology
- Otolaryngology
- Evidence-Based Medicine
Background:
- Chloroquine and hydroxychloroquine are 4-aminoquinoline derivatives used for malaria and autoimmune diseases.
- Auditory system side effects are frequently reported for these medications.
- A systematic review is needed to evaluate the evidence linking these drugs to hearing disorders.
Purpose of the Study:
- To systematically review and synthesize existing literature on hearing disorders in patients using chloroquine or hydroxychloroquine.
- To assess the association between the use of these 4-aminoquinoline derivatives and audiological alterations.
Main Methods:
- Systematic review including observational and interventional studies.
- Audiological assessment data from participants using chloroquine/hydroxychloroquine.
- Methodological quality assessed using the Meta-Analysis of Statistics: assessment and review Instrument.
- Certainty of evidence evaluated using the GRADE tool.
Main Results:
- 17 studies were included in the qualitative synthesis, with 5 in the meta-analysis.
- No statistically significant odds ratio for hearing disorders was found (OR=0.76, 95% CI=0.41-1.39).
- Low heterogeneity (I2=0%) was observed across studies.
Conclusions:
- Current evidence suggests no association between chloroquine/hydroxychloroquine use and hearing disorders.
- The certainty of evidence was rated as very low due to risk of bias, indirectness, and imprecision.
- Further high-quality research is recommended to confirm these findings.
