Insights
Invasive candidiasis, a rare fungal infection in children, can affect those with cystic fibrosis (CF). This case highlights the need for vigilant monitoring and potentially combination antifungal therapy for CF patients with invasive Candida infections.
Area of Science:
- Pediatric Infectious Diseases
- Mycology
- Cystic Fibrosis Research
Background:
- Invasive candidiasis is uncommon in pediatric patients post-neonatal period.
- Risk factors include immunodeficiency, compromised barriers (gastrointestinal, skin), and antibiotic use.
- Cystic Fibrosis (CF) patients may be susceptible due to underlying health issues.
Observation:
- A 10-month-old female with cystic fibrosis presented with failure to thrive and pulmonary symptoms.
- Blood cultures revealed Candida albicans, treated with liposomal amphotericin B.
- A subsequent osteoarticular infection (left knee) caused by C. albicans occurred.
Findings:
- Initial liposomal amphotericin B therapy showed insufficient response for the osteoarticular infection.
- Combined therapy with fluconazole and flucytosine led to patient recovery.
- No long-term sequelae were observed after a 4-year follow-up.
Implications:
- Invasive Candida infections are a potential complication in pediatric cystic fibrosis patients.
- Preventive strategies may be beneficial for at-risk CF individuals.
- Prolonged combination antifungal treatment might be necessary for invasive infections in this population.
Abstract:
Invasive candidiasis is rare in children after the neonatal period, but can occur in children with (secondary) immunodeficiency with a damaged gastrointestinal or skin barrier, or when receiving antibiotics. A 10-month-old girl was diagnosed as suffering from cystic fibrosis (CF) when showing failure to thrive, pulmonary symptoms and hypoproteinaemia. At that time, Candida albicans was identified from blood culture and treated intravenously with liposomal amphotericin B for 13 days. Six weeks later, the girl presented with osteoarticular infection of the left knee caused by C. albicans. The infection showed insufficient response to therapy with liposomal amphotericin B, but the patient recovered after therapy with fluconazole and flucytosine. Follow-up over 4 years revealed no sequelae. In conclusion, invasive Candida infections may occur in patients with CF, and preventive measures might be considered in patients at risk. In the case of an invasive infection, prolonged treatment with a combination of antifungal drugs may be required.

CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Infection
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Defense Mechanism Against Infection
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...
