Invasive candidiasis

Invasive candidiasis is a severe infection caused by a type of fungus called Candida. This infection can occur in the bloodstream and spread throughout the body, causing severe symptoms and complications. It is most common in people with weakened immune systems, such as those in intensive care units, those with organ transplants, and those with cancer.

Causes

Invasive candidiasis is caused by the Candida species of fungi. There are over 20 species of Candida that can cause infection in humans, the most common of which is Candida albicans. These fungi are normally present in the mouth, gut, and vagina without causing symptoms. However, in certain conditions, they can multiply and invade the bloodstream, leading to invasive candidiasis.

Risk Factors

Certain individuals are at a higher risk of developing invasive candidiasis. These include:

• People with weakened immune systems, such as those with HIV/AIDS, cancer, or organ transplants
• People in intensive care units
• People with diabetes
• People who are taking broad-spectrum antibiotics
• People with central venous catheters

Symptoms

The symptoms of invasive candidiasis can vary depending on the organs affected. They may include:

• Fever and chills that do not improve with antibiotics
• Pain or discomfort in the affected area
• Skin rash

Diagnosis

Invasive candidiasis can be difficult to diagnose as the symptoms are similar to those of other illnesses. The diagnosis is usually confirmed by blood tests that detect Candida in the blood. Other tests may include imaging studies such as CT scan or MRI, and tissue biopsy.

Treatment

The treatment for invasive candidiasis usually involves antifungal medications. The choice of medication depends on the species of Candida causing the infection and the patient's overall health. In severe cases, surgery may be needed to remove infected tissue.

Prevention

Prevention strategies for invasive candidiasis include proper hand hygiene, careful use of antibiotics, and early removal of central venous catheters.
