A group of top scientists has issued a grave warning about the growing threat presented by fungal illnesses, which are becoming resistant to antifungal medicines. This week's publication in The Lancet underscores the critical need for global action on antifungal resistance, as it could exacerbate the ongoing antimicrobial resistance (AMR) crisis.

Researchers from the University of Manchester, the Westerdijk Institute, and the University of Amsterdam conducted the analysis. They say that, while much of the global focus has been on bacterial resistance, fungal pathogens—which cause around 3.8 million deaths each year—are rapidly developing resistance to current antifungal medications. Many of these fungal diseases are becoming difficult, if not impossible, to treat due to increasing resistance.

The report's authors emphasise the critical need to widen the AMR discourse to encompass fungal infections, notably at the upcoming United Nations AMR summit in September. The scientists suggest that resistance has become the norm rather than the exception for the four antifungal therapy classes that are currently accessible.

The report, co-authored by Dr. Norman van Rhijn from the University of Manchester and Professor Ferry Hagen from the University of Amsterdam, emphasises the growing issue of fungal resistance, which is often overlooked. However, many drug resistance issues in recent decades have been caused by invasive fungal illnesses that have received little attention from scientists, governments, doctors, and pharmaceutical firms.

One of the key obstacles in treating fungal infections, according to the paper, is the biochemical similarity between fungal and human cells, which makes it difficult to produce medications that target fungus without injuring patients. In recent years, promising novel treatments, including new classes of compounds, have entered clinical trials, despite the challenges of producing them. This has reduced therapy options and increased the resistance problem. However, even before they reach the market, the agrochemical sector develops fungicides with comparable modes of action, which leads to cross-resistance. That puts us back at square one."

The scientists recognise the importance of antifungal medicines in agriculture for protecting critical crops and ensuring food security. However, they express concern about the extensive use of fungicides in agriculture and the resulting resistance to human infections. As Professor Hagen stated, "The question is, at what price?"

The experts emphasised the need for three essential activities in addressing the growing issue of fungal resistance. First, they advocated for a global ban on the use of certain antifungal compounds, limiting their usage to specified situations to prevent the rapid development of resistance. This parameter, they suggest, is critical to maintaining the efficacy of current treatments.

Furthermore, the scientists emphasised the need to work together to create solutions that address not only human health but also food security and the well-being of animals and plants. Fungal infections have an impact on crops and ecosystems; thus, an integrated approach that takes into account the larger picture of agriculture and biodiversity is critical.

A major proposal from the experts is to prioritise fungal diseases in discussions about antimicrobial resistance (AMR), particularly at the upcoming United Nations summit in September. They argued that global health agendas should recognise fungal resistance as a key problem, similar to bacterial resistance.

The scientists cautioned that if no prompt and coordinated worldwide action is taken, humanity will face a deteriorating health problem as fungus resistance spreads quickly. This would complicate the fight against AMR, making future management of infectious diseases much more complex.
