Candida infections in neonatal intensive care units can cause significant morbidity and mortality, so the document recommends measures to prevent, diagnose, and treat candidiasis in high-risk infants through practices like limiting unnecessary antibiotic use, considering fluconazole prophylaxis if infection rates remain high, and initiating empirical antifungal therapy in infants with risk factors like previous broad-spectrum antibiotic exposure. A diagnosis of candidiasis should prompt removal of foreign materials, treatment with antifungals like fluconazole or amphotericin B, and monitoring until cultures are cleared from sites like blood and urine.

Fungal infections can occur due to the increasing use of broad-spectrum antibiotics and patients with immunodeficiency. Some pathogens, such as Cryptococcus, Candida,and Fusarium, rarely cause serious diseases in the normal host, while other endemic fungi, such as Histoplasmosis, Coccidiodes,and Paracoccidiodes can cause disease in a normal host, but has a tendency to be aggressive on immunocompromise.
Candida species are normal flora that may be an apportunistic pathogen. Candidiasis occurs in some diseases such as gastrointestinal mucosal esophagitis, a fungal disease associated with the use of catheters and in - patients who have mucosal damage or obtain broad – spectrum antibiotics. Other candidiasis consist of skin candidiasis, funguria candidiasis, disseminated candidiasis and endocarditis candidiasis. Candidemia is the fourth most common cause of nosocomial bloodstream infections in the United States and in many of the developed country. Invasive candidiasis has a significant impact on patient outcomes, and it has been estimated that the mortality of invasive candidiasis is as high as 47%. The mortality rates are 15%-25% for adults and 10%-15% for neonates and children. Diagnostic approach to fungal infection is a priority. The knowledge of the changes in epidemiology and risk factors for fungal infections, has become the main reference to measure optimal treatment of fungal infections.

Thrush is a fungal (yeast) infection that can grow in the mouth, throat and other parts of the body.
It is caused by the overgrowth of a type of fungus called Candida.
Mouth and throat thrush is called oropharyngeal candidiasis.
Oral thrush also known as oral candidiasis, is a fungal infection of the mouth.
It was first described by a French pediatrician; Francois Veilleux, in 1838.

4. Introduction
infection with Candida species is associated with significant morbidity
and mortality in infants.
Extremely low birth weight (ELBW; <1000 g) infants carry the
highest burden of disease.
The incidence of candidiasis in ELBW infants is approximately 10%,
although it varies as much as 20-fold between centers.
Neonatal candidiasis is associated with 20% mortality, and 50% of
survivors have severe neurodevelopmental impairment.
kidneys, are prime locations for end-organ damage due to
candidiasis in infants.
End-organ damage in the central nervous system, heart, and
genitourinary tract is also common.
5. Diagnosis
The blood culture is the gold standard for detection of candidiasis, although its
sensitivity is poor.
Even with multiple organs infected with candidiasis, the sensitivity of blood
culture to detect infection in adults is only 50%.
The small blood volume used for culture in infants makes isolation
of Candida species in blood (candidemia) even more difficult.
Because four or more vital organs are typically involved prior to documentation of
candidemia, a positive blood culture for Candida should almost never be
considered a contaminant and should generally be regarded as the “tip of the
iceberg” for infection.
Even when blood culture is able to diagnose Candida, the time to detection of the
organism can be problematic - median time to detection of Candida species from
blood culture in infants is 36 hours and increases to 42 hours when the infant is
receiving antifungal therapy.7
6. Even more difficult than diagnosing candidemia is diagnosis of central
nervous system involvement. Only 37% of infants with proven candidal
meningitis also had positive blood cultures for Candida.
In addition, normal cerebrospinal fluid (CSF) parameters are present in 50
%of infants with candidal meningitis.
other methods.
1,3-β-D-glucan is a fungal cell wall component that has been used to diagnose a variety of fungal
infections, including Candida. Levels of this polysaccharide can be detected
spectrophotometrically. Although several studies have shown promising results in adult leukemic
patients with relatively high specificity for this method, the sensitivity is only 50-60%.
Polymerase chain reaction (PCR) testing has also been used to detect Candida DNA in blood
and serum samples. This method has yielded promising results based on several small studies, with
sensitivity to detect fungal disease equal to or higher than blood culture.
Enzyme and PCR assays, however, remain experimental methods. These tests have not been
validated in infants, and further studies are needed to evaluate their usefulness.
7. Risk factors associated with Candida infection in
infants
gestational age and birth weight
prolonged exposure to empiric antibiotics (greater than 48
hours despite negative blood cultures)
Exposure in the seven days before blood culture. to third-
generation cephalosporins and other broadly-acting antibiotics
such as carbapenems and beta-lactam/beta-lactamase inhibitor
combinations.
8.
9.
10. prevention of Candida infection
The following steps should be taken:
1) avoid the use of third-generation cephalosporins;
2) avoid the use of unnecessarily prolonged courses of antibiotics;
3) minimize the use of foreign bodies such as central venous or
arterial catheters and other hardware; and
4) institute strict hand hygiene policies.
11. If, despite these measures, Candida incidence remains high (greater than
10% within a particular gestational age or birth weight stratum), then
antifungal prophylaxis should be considered for high-risk infants.
Fluconazole prophylaxis has been shown to reduce colonization and
prevent invasive fungal infection.
The recommended dose of fluconazole is 6 mg/kg twice weekly.
12. Treatment
Empirical antifungal therapy should be considered in high-risk infants
once Candida infection is suspected. Infants at highest risk
for Candida who may benefit most from empirical antifungal therapy
include
those less than 25 weeks gestational age,
those with thrombocytopenia at time of blood culture,
and those with a history of third-generation cephalosporin or carbapenem
13. selection of antifungal therapy.
Antifungal agents act via a variety of mechanisms, including
inhibition of cell wall or cell membrane synthesis,
disruption of cell membrane integrity,
and interference with fungal DNA and RNA synthesis.
For many of these agents, the appropriate dosing recommendations in
infants have only recently been elucidated.
14. Polyenes(amphotericin B, Fungizone)
includes amphotericin B deoxycholate (AMBD), liposomal amphotericin
B (L-AmB), and amphotericin B lipid complex (ABLC). These agents act
by binding to ergosterol (a sterol in fungal cell membranes), resulting in
the leaking of small organic molecules and eventual cell death. AMBD is
the most commonly used agent to treat systemic Candida infections in
infants.
and recommended dosing is 1 mg/kg/day.
amphotericin B lipid products, although a dose of 5 mg/kg/day of
liposomal amphotericin B is generally considered reasonable.
15.
16. 5-fluorocytosine
converted to other metabolites that disrupt fungal DNA and
RNA synthesis.
5-FC is almost exclusively used in combination with other
antifungal therapies, as monotherapy with 5-FC can lead to
resistant organisms.
5-FC may be associated with delayed clearance of Candida from
the CSF in neonates.
17. Triazoles
The triazole antifungal class includes fluconazole, itraconazole, posaconazole, and
voriconazole. (Vfend)
These drugs represent an oral alternative to intravenous antifungal therapies.
Triazoles inhibit a cytochrome P–450-dependent enzyme (lanosterol c14 demethylase)
that is needed to make ergosterol, a sterol of fungal cell membranes.
Fluconazole has excellent activity against Candida and is used routinely in infants.
Itraconazole, posaconazole, and voriconazole can also be used to treat Candida,
although their primary use is their extended spectrum activity against molds.
18. Of the mold-active agents, only voriconazole has been studied in
infants.
Pharmacokinetic analysis of voriconazole has revealed extreme
variability in serum concentration with respect to weight-based
dosage.
The unpredictable pharmacokinetic response combined with
known hepatotoxicity of this agent underscores the need for
therapeutic drug monitoring.
الكبدية السمية مع جنب إلى اًبجن المتوقعة غير الدوائية الحركية االستجابة تؤكد
العالجية األدوية مراقبة إلى الحاجة على العامل لهذا المعروفة.
19. Thus, except in rare cases of Aspergillus infection or infection
with Candida species resistant to fluconazole (such as C.
glabrata or C. krusei), voriconazole should be considered a drug
of last resort in the intensive care nursery.
------------------------------
Fluconazole( Diphlucan) has been shown to be safe and effective
in the treatment of invasive candidiasis in infants.
Although fluconazole is renally excreted with minimal hepatic
metabolism, its most concerning side effect is hepatotoxicity that
is not related to amount or duration of exposure.
20. Fluconazole dosing adjustments therefore are made based
on renal function rather than liver function.
Because fluconazole exhibits fungistatic activity that is
time-dependent, optimal dosing incorporates area-under-
the-curve (AUC) dosing target.
Adult dosing of fluconazole in stable patients consists of a
loading dose (12 mg/kg) followed by (6 mg/kg) daily.
This dosing provides adequate drug for adults to maintain
an AUC of 400–800 mg*hr/L.
To achieve similar exposures, infants require 12 mg/kg/day.
In addition, a loading dose of 25 mg/kg results in more
rapid achievement of therapeutic levels and was found to be
safe in a small cohort of infants.
21. Because more immature infants have delayed clearance of
fluconazole, infants who are less than 30 weeks gestational age
and less than 2 weeks postnatal age who have a creatinine level
>1 mg/dL should be given a loading dose of 12 mg/kg.
Creatinine level should be monitored, and if creatinine remains
>1 mg/dL, then 6 mg/kg/day dosing should be considered; if
creatinine drops to <1 mg/dL, then 12 mg/kg/day should be
continued.
25. Echinocandins
The echinocandins (anidulafungin, caspofungin, and micafungin)
act at the fungal cell wall and inhibit 1,3-β-D-glucan synthesis.
These agents do not penetrate the CSF, but they are able to
penetrate brain tissue.
The echinocandins do not, however, penetrate the vitreous;
infants being considered for treatment with these agents must
undergo dilated retinal exam to exclude endophthalmitis.
Based on data from randomized controlled trials, the
echinocandins are recommended as first-line agents in adults and
older children for candidemia and disseminated candidiasis.
26. In the intensive care nursery, the echinocandins are emerging as
an alternative therapy for Candida infections.
Most of the available neonatal pharmacokinetic data are for
micafungin. Several pharmacokinetic studies of micafungin at
doses ranging from 1.5–15 mg/kg/day have been performed in
infants.
The current recommended dose is 10 mg/kg/day, with no
adjustment needed for renal or hepatic impairment.
27.
28. Summary and recommendations
Candidiasis in the intensive care nursery results in
substantial morbidity and mortality.
Prevention of infection is possible via modification of
risk factors.
Early diagnosis is critical, and treatment should be
initiated promptly with appropriate antifungal agents.
Empirical antifungal therapy should be considered
when Candida is suspected in ELBW infants.
29. When infection with Candida is diagnosed, the following steps
should be followed:
1) Central venous and arterial catheters should be removed.
Temporary, peripheral access should be used for several days while
the patient is receiving antifungal therapy until documentation of
negative blood cultures.
2) First-line therapy for candidiasis should be initiated. Choice of
therapy includes:
Fluconazole 12 mg/kg/day (25 mg/kg loading dose)
Amphotericin B deoxycholate 1 mg/kg/day
Liposomal amphotericin B 5 mg/kg/day (if urine cultures are
negative)
Micafungin 10 mg/kg/day (if eye involvement is excluded)
30. 3) Microbiologic clearance should be documented by
exhaustive search, including CSF culture, urine culture, two
negative blood cultures separated by greater than 24 hours,
dilated retinal exam by an ophthalmologist, and
echocardiogram.
Abdominal or central nervous system imaging should be
considered if there is concern about invasive candidiasis in
these areas.
.
31. 4) For uncomplicated candidemia or candiduria, length of
therapy should be 21 days after microbiologic clearance.
If cultures continue to be positive by day 7, the addition of
a second agent should be considered.
5) Patients should undergo follow-up to assess
neurodevelopmental outcome with intervention if needed
32. Take Massage
Empirical antifungal therapy should be considered in
those with a history of third-generation cephalosporin
or carbapenem exposure in the seven days before blood
culture.
