Methodologic assessment of the systematic reviews of ophthalmic adverse drug reactions published in Ophthalmology journals: a systematic review

Penedones A, Batel-Marques F

PURPOSE:

This systematic review aims to characterize and review the methodology of the systematic reviews reporting ophthalmic adverse drug reactions.

METHODS:

This systematic review followed the Cochrane Collaboration and the Preferred Reporting Items for Systematic Reviews and Meta-analyses guide. MEDLINE and EMBASE databases were searched, by all Ophthalmology journals. All systematic reviews reporting ophthalmic adverse drug reactions in the last decade were included. Data on methodology were extracted. Methodological quality was assessed through A MeaSurement Tool to Assess systematic Reviews 2 scale. Descriptive analysis was performed.

RESULTS:

Twenty-one systematic reviews were identified. Almost 60% of the systematic reviews reported non-ophthalmic drugs. Nine (43%) systematic reviews did not follow any recommendation. A search filter was not applied in 48% systematic reviews. Observational data was the source of information most included. The methodological quality was assessed in 57% systematic reviews. A meta-analysis was performed in 57% systematic reviews. The protocol’s elaboration, the explanation of the sources of information and the list of excluded articles were the domains less performed in the systematic reviews.

CONCLUSION:

The systematic reviews reporting ophthalmic adverse drug reactions diverged in some methodological aspects. Such an issue deserves further investigation, since discrepancies may lead to biased conclusions and, consequently, impact clinical and/or regulatory decisions.

Testing the usefulness of the number needed to treat to be harmed (NNTH) in benefit-risk evaluations: case study with medicines withdrawn from the European market due to safety reasons.

Mendes D, Alves C, Batel Marques F.

OBJECTIVE:

To explore the usefulness of number needed to treat to be harmed (NNTH), in benefit-risk assessments, by studying the agreement between NNTH values and withdrawals of medicines from European market due to safety reasons.

METHODS:

Medicines with data from longitudinal studies were included. Studies were identified from European Medicines Agency’s Reports. Meta-analyses were performed to pool odds ratios (OR) with 95% confidence-intervals (CI). Published control event rates were applied to ORs to calculate NNTHs (95%CI) for selected adverse events.

RESULTS:

NNTH (95%CI) decreased from pre- to post-marketing for the eight medicines included: peripheral neuropathy (∞ vs. 12[non-significant; NS] with almitrine; heart valve disease with benfluorex (∞ vs. NNTH ranging from 7[4-13] to 7[5-9]); myopathy (-4096[NS] vs. 797[421-1690]), new-onset diabetes (113[NS] vs. 390[425-778]), bleeding (∞ vs. 517[317-1153]), and infection (∞ vs. 253[164-463]) with niacin-laropiprant; psychiatric disorders (12[7-34] vs. 9[5-24]) with rimonabant; myocardial infarction (MI) [-1305 vs. 270[89-4362]) with rofecoxib; MI (-510 vs. NNTH ranging from 152[55-4003] to 568[344-1350]) with rosiglitazone; cardiovascular events (∞ vs. 245[129-1318]) with sibutramine; and liver injury (∞ vs. 5957[NS]) with ximelagatran.

CONCLUSION:

NNTH have potential of use as a supportive tool in benefit-risk re-evaluations of medicines and may help regulators to making decisions on drug safety.
