Efficacy of lotilaner against myiasis caused by Cochliomyia hominivorax (Diptera: Calliphoridae) in naturally infested dogs

Efficacy and Safety of Lotilaner Ophthalmic Solution 0.25% in the Treatment of Demodex Blepharitis: A Systematic Review and Meta-Analysis

PURPOSE

To evaluate the safety and efficacy of Lotilaner ophthalmic solution 0.25% in the treatment of demodex blepharitis.

METHODS

PubMed, Web of Science, Scopus, and Embase databases were searched. RCTs comparing lotilaner with placebo or any other standard treatments were included. Outcomes of mean collarette grade (MCG), mite density (Md), meaningful collarette reduction (MCR), mite eradication (ME), were pooled as mean difference (MD), and the outcomes of erythema cure (EC), collarette cure (CC) adverse events (AE) as risk ratio (RR) with their 95% confidence interval (CI) between the two groups from baseline to the endpoint. Review Manager (Version 5.4.1) software was used to conduct all statistical analyses.

RESULTS

Four RCTs (947 patients) were included in this study. The overall effect favored the lotilaner group in terms of mean collarette grade upper lid (MD -0.99, 95% CI [-1.26, -0.72]), MCG lower lid (MD -0.57, 95% CI [-1.03, -0.11]), Md (MD -1.13, 95% CI [-1.47, -0.79]), MCR (MD 2.07, 95% CI [2.27, 3.21]), ME (MD 3.46, 95% CI [2.96, 4.04]). EC (RR 3.16, 95% CI [2.18 to 4.59]) and CC (RR 4.17, 95% CI [2.97 to 5.85]). No significant difference between the two groups in terms of AE (RR 1.25, 95% CI [0.75 to 2.06]). However, these findings are limited by significant heterogeneity in some of the reported outcomes.

CONCLUSIONS

Our findings show that lotilaner might effectively treat Demodex blepharitis. However, further RCTs with larger and more diverse populations are needed to confirm these findings as some outcomes show significant heterogeneity.

The current status and outlook for insecticide, acaricide and anthelmintic resistances across the Australian ruminant livestock industries: assessing the threat these resistances pose to the livestock sector

The Australian ruminant livestock industries are faced with the need to control parasitic infectious diseases that can seriously impact the health of animals. However, increasing levels of resistance to insecticides, anthelmintics and acaricides are substantially reducing the ability to control some of these parasites. Here we review the current situation with regard to chemical resistances in parasites across the various sectors of the Australian ruminant livestock industries and assess the level of threat that these resistances pose to the sustainability of these sectors in the short to long terms. We also look at the extent to which testing for resistance occurs across the various industry sectors, and hence how well-informed these sectors are of the extent of chemical resistance. We examine on-farm management practices, breeding of parasite-resistant animals, and non-chemical therapeutics that may act as short to long term means to reduce the current reliance on chemicals for parasite control. Finally, we look at the balance between the prevalence and magnitude of current resistances and the availability and adoption rates of management, breeding and therapeutic alternatives in order to assess the parasite control outlook for the various industry sectors.
