Congenital candidiasis is a severe complication of candidal vulvovaginitis. It occurs in two forms,congenital mucocutaneous candidiasis and congenital systemic candidiasis. Also newborns are in age group the most vulnerable to invasive candidiasis. Congenital candidiasis should be considered as an interdisciplinary problem including maternal and fetal condition (including antibiotic therapy during pregnancy), birth age and rare genetic predispositions as severe combined immunodeficiency or neutrophil-specific granule deficiency. Environmental factors are no less important to investigate in diagnosing, treatment and prevention. External factors (e.g., food) and microenvironment of human organism (microflora of the mouth, intestine and genitalia) are important for solving clinical problems connected to congenital candidiasis. Physician knowledge about microorganisms in a specific compartments of the microenvironment of human organism and in the course of defined disorders of homeostasis makes it easier to predict the course of the disease and allows the development of procedures that can be extremely helpful in individualized diagnostic and therapeutic process.

Neonatal Candida infections are the leading cause of invasive fungal infections that might cause severe morbidity or mortality in a large majority of those affected. Although Candida albicans has been the most common species, Candida parapsilosis is increasingly being recognized as an important cause of invasive candidiasis in neonates. Among the Candida species, C. parapsilosis has been commonly isolated and shown to be less susceptible in vitro to echinocandins than other Candida species. We report an infant who had refractory C. parapsilosis septicemia cured with caspofungin.

Recent literature data reveals the most common etiological agents of congenital parasitoses to be Toxoplasma gondii, Trypanosoma cruzi, Leishmania donovani and Plasmodium falciparum. An analysis of clinical data indicates that parasitic congenital infections are often asymptomatic, whereas symptomatic newborns usually display nonspecific symptoms, which greatly hinders correct diagnosis. The long-term consequences of prenatal infections are serious clinical problems. This article presents the possible routes of vertical transmissions (mother-to-child) of pathogens including prenatal, perinatal, as well as postnatal routes. It highlights the role of factors involved in protozoa transmission and development of congenital parasitic diseases, such as parasite genotypes, the relationship between the timing of maternal infection and the probability of passage of the parasite through the placental barrier, and the immunological features of pregnant women. Acquired and congenital babesioses in human and experimental animals are presented. It emphasises that the mechanisms by which parasites infect the placenta and cross from mother to fetus are still poorly understood. It also describes the cellular mechanisms of infection by T. gondii, such as tachyzoites crossing biological barriers, the expression of Toll-Like Receptors (TLR) family on trophoblasts and syncytiotrophoblasts as an immune response to intrauterine infection and cases of congenital and acquired toxoplasmosis, as well as the long-term consequences of congenital invasion with T. gondii, episodes of reactivation of latent toxoplasmosis and T. gondii reinvasions. Mycological topics include a rare case of in utero fungal infection of offspring by a mother with vaginal candidosis, and the fungal contamination of ward facilities and medical equipment as potential sources of exogenous infections of newborn children.

Candida endocarditis is extremely rare in term neonates, and gall bladder involvement due to candidemia has never been reported amongst neonates and infants. A term, appropriate for gestational age neonate developed Candida tropicalis blood stream infection in second week of life. He was started on conventional amphotericin B. However, he failed to show any clinical improvement, and candidemia keep on persisting. Repeat sanctuary sites screening revealed multiple echogenic masses in heart (vegetations) and gall bladder. On changing the treatment to liposomal amphotericin B and fluconazole, he recovered clinically, echogenic masses in gall bladder disappeared, and intracardiac vegetations decreased in size.

This is the first reported case of maternal sepsis and placental transmission of Candida kefyr to premature fraternal twins. The mother consumed organic dairy products regularly throughout her pregnancy and developed sepsis with chorioamnionitis caused by C. kefyr. The twins developed respiratory distress at birth. The placenta, fetal membranes, and umbilical cords showed numerous colonies of yeasts, subsequently identified as C. kefyr. C. kefyr sepsis in preterm neonates should be considered when there is a significant maternal history of organic dairy product consumption during pregnancy.

Congenital candidiasis presents with a variety of clinical features. We report two neonates with congenital candidiasis characterized by diffuse erythematous papules associated with pneumonia and respiratory distress. Candida pseudohyphae were identifiable in skin scrapings. Systemic cultures were negative, but urine and sputum cultures grew Candida albicans. After prompt systemic antifungal therapy, the infants were discharged from hospital with no overt complications. This report highlights the presence of characteristic skin lesions associated with candidal infection, occurring within 24 hours of birth. This is an important observation which could help in the early diagnosis of congenital candidal infection.

The appearance of Candida albicans in three patients made physicians investigate an outbreak. Outbreak description and microbiologic screening: Case 1 developed C. albicans in the placenta culture and in the blood culture carried out on the 8th day of birth. Four days after this candidemia, C. albicans was recovered in a catheter tip of a second neonate (case 2) and finally five days later other newborn (case 3) developed C. albicans in the hemoculture. After that, the hands of all caregivers as well as case 3's incubator, case 1's mother, and from all nine neonates in the unit were studied with swabs. A wet mount was done to all swabs and then they were cultured in Chromagar Candida and SDA. All C. albicans were studied by RAPD. RAPD study showed that C. albicans recovered from placenta and blood cultures of case 1, the catheter tip of case 2 and the blood culture of case 3, resulted to be identical and these yeasts were related to the C. albicans from the mouth of case 1 mother and the mouth of another colonized newborn. C. albicans was not found in the others swabs. The isolations of identical C. albicans allowed to suppose the horizontal transmission from the case 1, that had acquired it congenitally. Not only isolation of unusual Candida species would be an alert. Despite patients' personal factors to justify a fungal infection, the recovery of C. albicans in a short period of time should warn physicians about the possibility of a horizontal transmission.

A premature newborn born to a mother with candidal vaginitis developed congenital invasive candidiasis. The isolates of Candida albicans from the bloodstream and the oral cavity of the neonate and the vagina of the mother shared a common genotype, which provide direct evidence of the association of congenital candidiasis with candidal vaginitis in the mother.

BACKGROUND: Colonization by Candida species is the most important predictor of the development of invasive fungal disease in preterm neonates, and the enteric reservoir is a major site of colonization. We evaluated the effectiveness of an orally supplemented probiotic (Lactobacillus casei subspecies rhamnosus; Dicoflor [Dicofarm spa]; 6 x 10(9) cfu/day) in the prevention of gastrointestinal colonization by Candida species in preterm, very low birth weight (i.e., < 1500-g) neonates during their stay in a neonatal intensive care unit. METHODS: Over a 12-month period, a prospective, randomized, blind, clinical trial that involved 80 preterm neonates with a very low birth weight was conducted in a large tertiary neonatal intensive care unit. During the first 3 days of life, the neonates were randomly assigned to receive either an oral probiotic added to human (maternal or pooled donors') milk (group A) or human milk alone (group B) for 6 weeks or until discharge from the NICU, if the neonate was discharged before 6 weeks. On a weekly basis, specimens obtained from various sites (i.e., oropharyngeal, stool, gastric aspirate, and rectal specimens) were collected from all patients for surveillance culture, to assess the occurrence and intensity of fungal colonization in the gastrointestinal tract. RESULTS: The incidence of fungal enteric colonization (with colonization defined as at least 1 positive culture result for specimens obtained from at least 1 site) was significantly lower in group A than in group B (23.1% vs. 48.8%; relative risk, 0.315 [95% confidence interval, 0.120-0.826]; P = .01). The numbers of fungal isolates obtained from each neonate (P = .005) and from each colonized patient (P = .005) were also lower in group A than in group B. L. casei subspecies rhamnosus was more effective in the subgroup of neonates with a birth weight of 1001-1500 g. There were no changes in the relative proportions of the different Candida strains. No adverse effects potentially associated with the probiotic were recorded. CONCLUSIONS: Orally administered L. casei subspecies rhamnosus significantly reduces the incidence and the intensity of enteric colonization by Candida species among very low birth weight neonates.

Candida septicaemia with multidrug resistance is an uncommon event in preterm neonates. We present an extremely low birth weight infant (gestational age of 27 weeks, birth weight of 980 g) who developed congenital Candida parapsilosis septicaemia. Because the fungus was resistant both to amphotericin B and fluconazole, caspofungin was chosen for therapy. The fungus was successfully eradicated without any clinical or laboratory adverse effects.

We present a full-term female infant with congenital candidiasis characterized by extensive vesicular and pustular skin lesions associated with pneumonia and severe respiratory distress that appeared during the first hours after birth. The patient was born by cesarean section with no history of rupture of membranes. The mother had a vaginal discharge 3 weeks before delivery. The diagnosis was made by culture of pustular fluid, which grew Candida albicans. Systemic cultures were negative. The infant required a very brief course of conventional mechanical ventilation in spite of impressive and extensive lung infiltrates on the chest radiograph. She made a very quick clinical recovery although it is remarkable that antifungal treatment with amphotericin B was begun very late in her clinical course at the time when she was showing obvious signs of major improvement. Current management guidelines strongly recommend specific therapy for infants with invasive congenital candidiasis or with burn-like extensive dermatitis even without lung involvement. We are not suggesting any change in these recommendations; however, at least in our patient, when amphotericin B was started, she was clearly recovering; it seems possible that her disease although extensive might have experienced an unusual spontaneous regression. This case can provide further insights into this unusual neonatal infection.

Two extremely premature infants died as a result of congenital Candida glabrata infection, and their placentas and umbilical cords were free of macroscopic Candida nodules. Because non-Candida albicans Candida infections are less likely to produce necrotic foci, we should not exclude Candida infections in the absence of macroscopic nodules on the placenta and umbilical cord.
