How complicated is Candida auris infection in the elderly?

Question

Hello doctor,

My 79-year-old mother was transferred from the hospital to a skilled nursing facility three weeks ago following hip replacement surgery. She was recovering well until routine screening revealed colonization with Candida auris. Since then, she has been placed in strict isolation, and staff members enter her room wearing full protective equipment, which has been frightening for her.

The infection control nurse explained that Candida auris is a dangerous, drug-resistant fungus. Although my mother currently has no symptoms, no fever, or signs of infection, she is being monitored closely. Two recent developments are particularly concerning: another resident has tested positive for the same organism, and my mother’s surgical wound recently showed unusual drainage, which has been sent for culture.

The facility appears very concerned, having restricted all visitors except immediate family and implemented enhanced cleaning protocols. Her latest lab results show a white blood cell count of 11,800 (up from 9,400 last week) and a slight elevation in C-reactive protein. Additionally, her diabetes has become more difficult to control, with blood sugars consistently running between 180 and 250 despite insulin adjustments.

I have several questions: If she is only colonized and not infected, why are such extreme precautions necessary? What is the likelihood that this will develop into an actual infection? How long might she need to remain in isolation? Several family members were planning to visit next month for her 80th birthday, so should they cancel those plans? And most importantly, if she does develop an infection, what treatment options are available, considering this fungus is resistant to most standard antifungals?

Please help.

Thank you.

Hello,

Welcome to icliniq.com.

I understand your concern.

Colonization means that the fungus is present on the skin or body surfaces without causing symptoms, whereas infection occurs when the fungus invades the skin or bloodstream, leading to noticeable symptoms. Even during the colonization stage, a patient can transmit the fungus to others, which is why strict precautions must be followed when handling your mother. This is known as isolation precautions, and such isolation can last for several weeks.

Unfortunately, this may mean that you will need to postpone your plans to visit at this time. Your mother is at high risk of developing an infection due to her prolonged hospital stay and her immunocompromised state. The nursing facility is doing the right thing by taking every precaution to protect her and others. If an infection does develop, the usual treatment involves antifungal medications such as Echinocandins.

If the strain is resistant, multiple antifungal agents may be required, making treatment more complex. It is important to be patient, continue following all recommended precautions, and allow the nursing home to monitor her closely until they can confidently lift the isolation measures.

I hope this helps.

Kindly follow up if you have more concerns.

Thank you.
