We herein report on two Japanese siblings with autoimmune polyglandular syndrome type 1 (APS-1). The brother, who expressed a characteristic phenotype of APS-1, had developed severe mucocutaneous candidiasis in early infancy and thereafter developed hypoparathyroidism and Addison's disease, along with a severe deterioration of his immunologic function. In contrast, the 44-year-old sister, who showed a noncharacteristic phenotype of APS-1, developed insulin-dependent diabetes with high anti-glutamic acid decarboxylase antibody, mild nail candidiasis, and autoimmune hepatitis with intact immunoreactivity. She had three susceptible human leukocyte antigen (HLA) loci for type 1 autoimmune diabetes. The expression of T cell receptor (TCR)V beta 5.1 increased in both patients, while the brother showed a widely suppressed expression of many TCRV beta families. Both individuals possessed compound heterozygous novel autoimmune regulator (AIRE) gene mutations (L29P and IVS9-1G > C). The same AIRE gene mutations can thus be associated with characteristic and noncharacteristic phenotypes of APS-1, and HLA may possibly influence the phenotype of APS-1.

Oral candidiasis is a common opportunistic infection of the oral cavity caused by an overgrowth of Candida species, the commonest being Candida albicans. The incidence varies depending on age and certain predisposing factors. There are three broad groupings consisting of acute candidiasis, chronic candidiasis, and angular cheilitis. Risk factors include impaired salivary gland function, drugs, dentures, high carbohydrate diet, and extremes of life, smoking, diabetes mellitus, Cushing's syndrome, malignancies, and immunosuppressive conditions. Management involves taking a history, an examination, and appropriate antifungal treatment with a few requiring samples to be taken for laboratory analysis. In certain high risk groups antifungal prophylaxis reduces the incidence and severity of infections. The prognosis is good in the great majority of cases.

Autoimmune polyendocrinopathy, candidiasis, and ectodermal dystrophy (APECED) also known as autoimmune polyglandular syndrome type I, is a rare autosomal recessive disorder that results in several autoimmune diseases due to mutations in the AIRE (autoimmune regulator) gene. A 39-year-old female patient developed chronic mucocutaneous candidiasis at 3 yrs, idiopathic hypoparathyroidism at 11 yrs, chronic hepatitis at 23 yrs, Addison's disease and diabetes mellitus type I at 27 yrs. In addition, the patient developed progressive muscular atrophy of unknown etiology at the beginning of the third decade, and is bedridden at the present time. Her grandparents, parents, brother and daughter did not develop any features of APECED, but her father died of hepatoma. Direct sequencing of the AIRE gene revealed a novel missense mutation at exon 1 (R15C), which was identified to be of maternal origin. The other mutation was not found despite repeated sequencing of the whole coding regions. The R15C mutation was not detected in patients with idiopathic hypoparathyroidism (N= 10), idiopathic Addison's disease (N = 3), and normal subjects (N = 55). Although we could not analyze the father's gene, these results suggest that the patient is probably a compound heterozygote of the AIRE gene, in which the other abnormal allele could not be identified by the present analytical method. These data are compatible with the recent review that only one defective allele was detectable in some patients with clinically evident APECED. We found only six Japanese patients compatible with diagnosis of APECED, indicating that this autoimmune disease is extremely rare in our country.

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is a rare autosomal recessive disorder, which is characterized by an immune-mediated destruction of endocrine tissues, chronic candidiasis and ectodermal disorders. In contrast to many other autoimmune diseases, APECED is associated with mutations of a single gene, designated autoimmune regulator (AIRE). We describe an APECED patient with severe deformities of the tibia with radiological signs of metaphyseal dysplasia in addition to candidiasis, hepatitis, diabetes mellitus and adrenal failure. In this patient, we identified a novel AIRE mutation in association with the C322fsX372 mutation in exon 8, which is frequently detected in Caucasian patients. The frame shift mutation G263fsX377 in exon 6 results in a protein lacking both PHD zinc-finger domains similar to the R257 X mutation. This novel mutation was not found in 50 German controls.

Invasive bacterial and candidal infections are known to involve the retina, but the natural history of the retinal lesions and the utility of ophthalmologic consultation in the critical care setting as a diagnostic tool are not well understood. We 1) performed weekly funduscopic examinations on 77 medical and surgical patients in intensive care units (ICUs), 2) analyzed results of serial ocular examinations in 180 non-neutropenic patients with candidemia, and 3) reviewed the English literature on the association of retinal lesions with disseminated bacterial or candidal infection (DBCI). We found that 15 (19%) of the ICU patients had retinal lesions consistent with DBCI. Of these 15, 1 had clearly sepsis-related retinal lesions, while 13 (87%) had 1 or more systemic disease that could have explained their retinal findings (6 diabetic retinopathy; 2 human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS) retinopathy; 2 hypertensive retinopathy; 1 hemolytic uremic syndrome, and 1 leukemia). Multivariate analysis revealed that systemic disease (odds ratio 8.37, 95% confidence intervals: 3.24-21.56) independently correlated with the presence of retinal lesions while DBCI, trauma, hyperalimentation, and transfusion of blood products were not independently predictive in any analysis. Twenty of the 180 (15%) candidemic patients had retinal lesions. Two (1%) had classic 3-dimensional white lesions with vitreal extension, and 5 (2.7%) had chorioretinal lesions without vitreal haziness. Notably, 10% of patients had superficial retinal hemorrhages and/or cotton wool spots that could have been due to either candidemia or a systemic disease (diabetes, hypertension, renal failure, closed head trauma). Concurrent bacteremia occurred in 3 of the 27 patients with eye lesions. Retinal lesions resolved in a mean of 33 days. None of the patients had symptoms at the time of the retinal finding. We found 3 studies that prospectively assessed retinal lesions in bacteremic patients. The frequency of retinal lesions in these series varied from 12% to 26%, with the most common lesions being cotton wool spots followed by superficial retinal hemorrhages. White-centered hemorrhages were seen in about 15% +/- 2 of bacteremic patients. Five studies prospectively evaluated candidemic patients for Candida endophthalmitis. These studies observed rates from 0% to 78% for lesions consistent with candidal endophthalmitis. Most studies performed recently found that nonspecific lesions such as cotton wool spots or superficial retinal hemorrhages occurred with a frequency of 11% to 20%. The availability of less toxic antifungal agents, more frequent use of empirical therapy, and the trend to early treatment may be altering the frequency of this complication. Observation of a classic 3-dimensional retina-based vitreal inflammatory process is virtually diagnostic of endogenous endophthalmitis due to Candida spp., but such lesions are relatively uncommon. Conversely, nonspecific lesions that could be due to bacterial or candidal endophthalmitis (cotton wool spots, retinal hemorrhages, and Roth spots) are seen frequently. These lesions are most often due to an underlying systemic disease rather than an infection. Serial examinations provide the best evidence that a given lesion is due to an intercurrent infection. The current low rate of vitreal extension of retinal process appears to be due to the high rate of empirical or therapeutic use of antifungal agents in high-risk patient groups. Ophthalmoscopy should be performed in patients with known candidemia. However, ophthalmoscopic examination seems to have little value in assisting with the discovery of occult disseminated candidiasis or bacterial infection.

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is an autosomal-recessive syndrome defined by two of the following conditions: chronic mucocutaneous candidiasis, hypoparathyroidism, or Addison's disease. Other autoimmune conditions may be associated, such as hypothyroidism, hypogonadism, insulin-dependent diabetes mellitus, chronic active hepatitis, pernicious anemia, vitiligo, alopecia, biliary cirrhosis, and ectodermal dysplasia. APECED is caused by mutations in the autoimmune regulator gene, mapping to 21q22.3. We report on three patients whose clinical and molecular features challenge the currently used diagnostic criteria for APECED. AR presented at 15 yr of age with a history of recurrent infections and mucocutaneous candidiasis. He is now 21 yr old, and no other signs or symptoms of APECED have appeared to date. DR presented at 7 yr of age with hypocalcemia and a prolonged Q-T interval on the electrocardiogram. He also had minor facial dysmorphisms and mild mental retardation. Serum calcium levels were low, PTH levels were undetectable, and hypoparathyroidism was therefore diagnosed. All other biochemical, immunological, and endocrinological tests were normal. DR is now 8 yr old with no other signs or symptoms of APECED. ST presented at 14 yr of age for alopecia aerata and pitted nail dystrophy and goiter. Thyroid function was normal in the presence of thyroid-specific antibodies. No other signs or symptoms of APECED have appeared to date. Genetic analysis revealed a typical mutation (R257X) on a single allele in both AP and DR; in ST, heterozygosity for a novel mutation (V484M) involving one of the zinc fingers of the plant homeodomain of the protein was found. The finding of a typical APECED mutation in two patients presenting with one isolated major clinical APECED feature and of a novel mutation in a patient presenting with atypical features of APECED onset suggests that the time might have come for updating the diagnostic criteria of this syndrome.

Eight Italian hospital or University gynecology clinics participated in a prospective survey of patients with culture-confirmed symptomatic vulvovaginal candidiasis (VVC) (October 1999 to March 2001). Of 1138 patients recruited in the study, 931 were evaluable. A recent history of VVC was documented in 43.5% patients (358/823) with a mean number of 2.9+/-2.7 episodes per patient (N=302). A total of 77 patients (10.0%) had a history of recurrent VVC (four and more episodes in a 12-month period). The most frequent associated factors were related to life style: synthetic fabric underwear, vaginal douching and bike, training bike and motorbike (about 1/3 each). Oral contraception was found in 20.8% patients, recent antibiotic use in 15.9% patients, current pregnancy concerned 10.3% patients while 3.4% patients were taking hormonal replacement therapy. Diabetes, corticosteroids or HIV were rarely encountered. Yeast was documented by direct microscopy in 78.3% patients (448/572). A positive culture was obtained in 98.3% patients (909/925). Candida albicans was the predominant species (77.1%), followed by Candida glabrata (14.6%) and Candida krusei (4.0%). With the exception of one center with a lower proportion of C. albicans, this latter represented between 75 and 85% of the isolates. Overall, this study confirmed the preponderant role played by C. albicans in either sporadic and recurrent VVC.

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is a rare autosomal recessive disorder, characterised by a loss of self-tolerance to endocrine tissues, chronic candidiasis and ectodermal disorders. APECED is associated with mutations of a single gene, designated autoimmune regulator (AIRE). We describe a 31-year-old APECED patient with non-traumatic, cutaneous ulcers on both forearms with features of a lupus-like panniculitis. On admission to the ICU in September 2001, the patient suffered from a ketoacidotic, hyperglycemic coma and adrenal crisis due to an Enterobacter-cloacae sepsis, originating from multiple, necrotising deep cutaneous ulcers. These ulcers spontaneously developed on both forearms, some of which were just emerging, full blown or healing with scars. Histological examination showed signs of a scarring panniculitis and vasculitis. Immunohistochemistry and direct immunofluorescence with characterisation of immunoglobulin and complement-factor binding pattern revealed features of a lupus-like panniculitis. Sequence analysis of all 14 exons of the AIRE gene revealed a R257 X mutation in exon 6 resulting in a nonsense mutation at codon 257 confirming the diagnosis of APECED. Oral treatment with 60 mg/day corticosteroids for two weeks led to complete resolution of all ulcers. In conclusion, mutations in the AIRE gene may provide the genetic background against which additional factors can initiate an autoimmune process. Here, autoimmune panniculitis appears to be an associated feature of the APECED syndrome. Our findings support the use of immunosuppressive therapy for autoimmune disease components of the APECED syndrome.

Thirty cases of anogenital moniliasis were studied. Only five followed oral use of broad spectrum antibiotics. Although anogenital pruritus commonly follows the use of such drugs, it is rarely proved to be moniliasis, which is clinically diagnosed by symptoms of intertriginous denudation with satellite vesicopustules or the presence of cheesy, grossly detachable plaques. The diagnosis may be confirmed by microscopic observation of delicate hyphae and clusters of spores, or of chlamydospores on corn meal agar. One per cent aqueous gentian violet, 0.1 per cent gentian violet jel, or locally applied mercurials are the most effective forms of treatment, but effort must also be directed against predisposing factors (obesity, hyperhidrosis, oral or local use of broad spectrum antibiotics, diabetes and pregnancy).

A 12-year-old spayed female domestic longhair cat developed fungal cystitis (Candida sp). The cat had a history of chronic diabetes mellitus, hyperadrenocorticism, and bacterial cystitis caused by Escherichia coli. Antifungal agents (itraconazole and fluconazole) were administered orally without noticeable effect on the candiduria. Because of the ineffectiveness of these treatments, intravesicular administration of 1% clotrimazole solution was performed weekly for 3 treatments. Complete resolution of urinary candidiasis was detected after the third infusion. Intravesicular administration of clotrimazole solution appears to be a safe and effective treatment of fungal cystitis in cats.
