Despite its prevalence, more comprehensive retrospective analyses are needed to better understand this condition. Outcomes vary, with approximately two-thirds of cases achieving complete healing with retained vision, although enucleation is often necessary. Predominant pathogens include Aspergillus and Fusarium, with yeast reported in a minority of cases. Resistance to common antifungal agents among filamentous fungi poses a significant challenge. Advances in diagnostics, including repeat culture and antifungal susceptibility testing, as well as the incorporation of PCR technology, hold promise for improving detection and guiding treatment decisions. Newer antifungals, combination therapies, and innovative modalities such as photodynamic therapy offer hope for improved outcomes. Continued research efforts are essential to further elucidate the epidemiology, pathogenesis, and optimal management strategies for this condition.</p>","PeriodicalId":14658,"journal":{"name":"Javma-journal of The American Veterinary Medical Association","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141590250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clopidogrel reduces the risk of redeveloping ATE and delays recurrence of ATE in cats that have experienced an ATE episode. Consequently, cardiologists have recommended administering clopidogrel to cats as a primary preventative, suggesting that all cats with severe HCM be administered clopidogrel. However, clopidogrel is unpalatable in its manufactured format, making such administration problematic for many clients. Therefore, estimating the potential benefit of administration might help clinicians determine on a case-by-case basis the need to treat cats with clopidogrel. Relatively simple statistical analyses of currently available data, along with certain assumptions and extrapolations, allow such an estimation of benefit in terms of relative and absolute risk reduction conferred by clopidogrel. Using this approach, and provided certain assumptions are true, clopidogrel likely confers a reduction in risk of ATE in cats with moderate to severe HCM of approximately 3% to 4%. Given the difficulty of administering clopidogrel to cats, clinicians should weigh these relatively small potential benefits against the potential harms (difficulty of administration) and not necessarily insist that clients administer clopidogrel.</p>","PeriodicalId":14658,"journal":{"name":"Javma-journal of The American Veterinary Medical Association","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141431885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
