Características de las fungemias en un centro de referencia del Perú: retrospectiva de cinco años / Characteristics of fungemia in a peruvian referral center: 5-year retrospective analysis

RESUMEN Con el objetivo de conocer las características de las fungemias en 285 pacientes oncológicos hospitalizados del 2012 al 2016 en el Instituto Nacional de Enfermedades Neoplásicas se realizó un estudio descriptivo retrospectivo. Se evaluó información demográfica, clínica y microbiológica. Las fungemias por C. albicans predominaron en pacientes con tumores sólidos y sin neutropenia, mientras las causadas por C. tropicalis predominaron en pacientes con neoplasias hematológicas y neutropenia. C. tropicalis fue el agente más aislado (47,0%). Las fungemias aumentaron con el tiempo en los pacientes sin neutropenia. Las fungemias causadas por C. albicans aumentan con la edad en pacientes con tumores sólidos sin neutropenia. Se concluye que las fungemias son mayormente causadas por C. tropicalis en pacientes con neoplasias hematológicas con neutropenia y por C. albicans en pacientes con tumores sólidos sin neutropenia. Además, las fungemias en pacientes sin neutropenia aumentan en el tiempo y las causadas por C. albicans, en tumores sólidos sin neutropenia, aumentan con la edad.

ABSTRACT Retrospective descriptive study carried out to determine the characteristics of fungemia in 285 cancer patients hospitalized from 2012 to 2016 at the Instituto Nacional de Enfermedades Neoplásicas (INEN). Demographic, clinical and microbiological information was evaluated. Fungemia by C. albicans predominated in patients with solid tumors and without neutropenia, while those caused by C. tropicalis predominated in patients with hematological neoplasia and neutropenia. C. tropicalis was the agent isolated in most cases (47.0%). Fungemia increased over time in patients without neutropenia. Fungemia caused by C. albicans increases with age in patients with solid tumors without neutropenia. It is concluded that fungemia are mainly caused by C. tropicalis in patients with hematological neoplasia with neutropenia and by C. albicans in patients with solid tumors without neutropenia. In addition, fungemia in patients without neutropenia increases over time; and those caused by C. albicans increase with age in patients with solid tumors without neutropenia.

Huge Candida albicans normal native tricuspid valve endocarditis

Fungal endocarditis has become an important infection associated with medical progress and the modern lifestyle. In particular, Candida spp. is a rare but important cause of infective endocarditis. We report the case of a 28-year-old woman­quadriplegic and bedridden from birth­who died after repeated episodes of pneumonia treated with different regimens of intravenous antibiotics. A medico legal autopsy was performed, which diagnosed severe Candida native valve infective endocarditis (CIE). This case report illustrates the prolonged use of antibiotic treatment as a possible risk factor for the development of CIE. We also considered how the bedridden condition and the presence of a central venous catheter may be additional risk factors for the development of this entity. Finally, we examined the absence of peripheral embolization in the setting of endocarditis of the right side of the heart.

Antifungal activity of caspofungin in experimental infective endocarditis caused by Candida albicans

BACKGROUND Infective endocarditis is a disease characterised by heart valve lesions, which exhibit extracellular matrix proteins that act as a physical barrier to prevent the passage of antimicrobial agents. The genus Candida has acquired clinical importance given that it is increasingly being isolated from cases of nosocomial infections. OBJECTIVE To evaluate the activity of caspofungin compared to that of liposomal amphotericin B against Candida albicans in experimental infective endocarditis. METHODS Wistar rats underwent surgical intervention and infection with strains of C. albicans to develop infective endocarditis. Three groups were formed: the first group was treated with caspofungin, the second with liposomal amphotericin B, and the third received a placebo. In vitro sensitivity was first determined to further evaluate the effect of these treatments on a rat experimental model of endocarditis by semiquantitative culture of fibrinous vegetations and histological analysis. FINDINGS Our semiquantitative culture of growing vegetation showed massive C. albicans colonisation in rats without treatment, whereas rats treated with caspofungin showed significantly reduced colonisation, which was similar to the results obtained with liposomal amphotericin B. CONCLUSIONS The antifungal activity of caspofungin is similar to that of liposomal amphotericin B in an experimental model of infective endocarditis caused by C. albicans.

Candida arthritis in a patient diagnosed with spondyloarthritis

Abstract Candida arthritis is an unusual manifestation that usually affects the knees. A 35-year-old man presented with a 2-month history of pain and swelling in the right knee. Swelling persisted after anti-inflammatory treatment. Peripheric spondyloarthritis was considered, but methotrexate, sulfasalazine, and methylprednisolone did not reduce the swelling. Direct examination of synovial fluid and a culture were positive for Candida albicans. Intravenous and intra-articular amphotericin-B were administered. The arthritis regressed and a culture and direct staining showed negative results. Candida arthritis should be considered in patients with arthritis that is resistant to treatment and prolonged, even if risk factors are absent.

Psoriasis in autoimmune polyendocrine syndrome type I: A possible complication or a non-endocrine minor component.

Introduction: Autoimmune polyendocrine syndrome type I (APS I) is an autosomal recessive systemic autoimmune disorder, affecting primarily endocrine glands, in which chronic mucocutaneous candidiasis is an early and prominent manifestation. We describe the rare occurrence of unstable psoriasis (with onset of pustular lesions) in a case of APS I without mucocutaneous candidiasis. A patient presenting with unstable psoriasis (with onset of pustular lesions) was detected to have persistent hypocalcemia which led to the diagnosis of hypoparathyroidism. Subsequently he was found to have hypergonadotrophic hypogonadism, primary adrenal insuffi ciency (compensated), and coeliac disease, thus confi rming the diagnosis of APS I. Psoriasis is very rarely reported in APS I, possibly due to the protective effect of antibodies to Th17 cytokines, which are responsible for the occurrence of candidiasis in this syndrome. However, psoriasis could occur in APS I patients without mucocutaneous candidiasis, who lack these antibodies. In our patient, possible factors aggravating psoriasis include hypocalcemia due to hypoparathyroidism as well as coeliac disease via anti-tissue transglutaminase antibodies. However, defi ning psoriasis as a possible minor component of APS I would require further studies of the autoimmune regulator (AIRE) gene functions.

Success Rate and Risk Factors for Failure of Empirical Antifungal Therapy with Itraconazole in Patients with Hematological Malignancies: A Multicenter, Prospective, Open-Label, Observational Study in Korea

We assessed the success rate of empirical antifungal therapy with itraconazole and evaluated risk factors for predicting the failure of empirical antifungal therapy. A multicenter, prospective, observational study was performed in patients with hematological malignancies who had neutropenic fever and received empirical antifungal therapy with itraconazole at 22 centers. A total of 391 patients who had abnormal findings on chest imaging tests (31.0%) or a positive result of enzyme immunoassay for serum galactomannan (17.6%) showed a 56.5% overall success rate. Positive galactomannan tests before the initiation of the empirical antifungal therapy (P=0.026, hazard ratio [HR], 2.28; 95% confidence interval [CI], 1.10-4.69) and abnormal findings on the chest imaging tests before initiation of the empirical antifungal therapy (P=0.022, HR, 2.03; 95% CI, 1.11-3.71) were significantly associated with poor outcomes for the empirical antifungal therapy. Eight patients (2.0%) had premature discontinuation of itraconazole therapy due to toxicity. It is suggested that positive galactomannan tests and abnormal findings on the chest imaging tests at the time of initiation of the empirical antifungal therapy are risk factors for predicting the failure of the empirical antifungal therapy with itraconazole.

Candida albicans meningitis in an infant with noonan syndrome

Noonan syndrome is a rare disorder, characterized by several malformations such as dysplasia and stenosis of the pulmonary valve, atrial septal defect and a typical pattern of hypertrophic cardiomyopathy. We describe here a 1-month old girl, who was referred to our center with seizure and apnea. She had wide anterior fontanel, head circumference and sunset eye. Intaventricular hemorrhage by sonography and atrial septal defect and hypertrophy cardiomyopathy by echocardiography were detected. Clinical and laboratory findings of the patient were compatible with a diagnosis of Noonan syndrome, which was also confirmed by molecular analysis. Candida albicans was grown in the blood and cerebrospinal fluid cultures. Treatment with Amphotrycine B was started for the patient and she responded well to this therapy. Early diagnosis and appropriate diagnosis of a rare condition in the patient with such rare disease are the main keys to avoid further complications and even death of patient.

Fulminant candida infection in an infant with acrodermatitis enteropathica.

Acrodermatitis Enteropathica (AE) is an important nutritional disorder of children affecting both innate and cell mediated immunity. It predisposes to secondary bacterial and candida superinfections. We describe an infant with typical features of AE who had candida infection with a fulminant course. Need of early recognition and prompt initiation of therapy for fungal infection in AE is emphasized.

Etiología de episodios de neutropenia febril en pacientes adultos con cáncer hematológico y de órganos sólidos en el Hospital Clínico Universidad Católica, Santiago-Chile / Etiology of febrile neutropenia episodes among cancer patients from Hospital Clinico Universidad Catolica, Santiago-Chile

Introduction: The surveillance of febrile neutropenia (FN) episodes in every center allows adapt the antibiotic therapy guidelines to local epidemiology. Aim: To characterize clinical features and compare the FN etiology between hematological cáncer (HC) and solid organ cancer (SOC) in our center. Patients and Methods: Surveillance study in adult patients with FN admitted to Hospital Clinico Universidad Católica, in Santiago, Chile, from January 2004 to August 2007. Results: 154 FN episodes corresponding to 87 patients were included. Mean age: 47 ± 6 years-old; 71 percent had HC and 29 percent SOC. A clinical and/or microbiologically documented infection was recognized in 76 percent. Gastrointestinal 31.5 percent, upper respiratory 30.3 percent and lower respiratory 16.9 percent were the more frequent clinical focus. In 30.5 percent blood culture resulted positive: gram negative rods 51 percent, gram positive cocci 41 percent and yeasts 8 percent; being Escherichia coli 22 percent, S. coagulase negative (SCoN) 20 percent and Klebsiella pneumoniae 12 percent most frequent bacteria; 22.2 percent Enterobacteriaceae were ESBL producers and 55.6 percent 5CoN were methicillin resistant. In 18.3 percent of FN episodes the etiology was not established. Highest mortality was observed in episodes with microbiologically documented infection (14.5 percent vs 1.3 percent, p < 0.005). A clinical observed focus and positive blood cultures were more frequently obtamed among HC than SOC associated episodes: 37.3 percent vs 13.6 percent; (p < 0.01) and 67.2 percent vs 50 percent; (p = 0.045), respectively. Conclusions: The etiological profile of FN in our center and the necessity to continue the surveillance was described. Future studies are needed regarding risk factors of invasive infection that have worst prognosis.

Introducción: La vigilancia de la etiología de los episodios de neutropenia febril (NF) en cada centro permite adaptar guías de antibioterapia a la epidemiología local. Objetivo: Caracterizar y comparar la etiología de la NF en pacientes con cáncer hematológico (CH) y de órganos sólidos (COS). Pacientes y Métodos: Estudio de vigilancia de NF de pacientes adultos en el Hospital Clínico Universidad Católica, en Santiago, Chile, entre enero 2004 y agosto 2007. Resultados: 154 episodios de NF correspondientes a 87 pacientes: 47 ± 6 años; 71 por ciento CH y 29 por ciento COS. Se documentó infección clínica y/o microbiológicamente en 76 por cientoo. Más frecuente fueron: foco gastrointestinal 31,5 por ciento, respiratorio alto 30,3 por cientoo y respiratorio bajo 16,9 por cientoo. En 30,5 por cientoo hubo hemocultivos positivos: bacilos gramne-gativos en 51 por ciento, cocáceas grampositivas en 41 por ciento, levaduras en 8 por cientoo; predominando: Escherichia coli 22 por cientoo, Staphylococcus coagulasa negativa (SCoN) 20 por cientoo y Klebsiella pneumoniae 12 por ciento; 22,2 por cientoo de las entero-bacterias eran productoras de (3-lactamasa de espectro expandido y 55,6 por cientoo >SCoN meticilina resistentes. En 18,3 por cientoo de los episodios no se identificó causa de fiebre. Hubo mayor mortalidad en episodios con documentación microbiológica (14,5 por ciento vs 1,3 por ciento, p < 0,005). En los pacientes con CH fue más frecuente obtener hemocultivos positivos (37,3 por cientoo vs 13,6 por ciento; p < 0,01) e identificar foco clínico (67,2 por ciento vs 50 por ciento; p = 0,045). Conclusiones: Se establece el perfil etiológico de las NF en nuestro centro y la necesidad de mantener vigilancia. En futuros estudios será necesario evaluar factores de riesgo de pacientes con infecciones invasores que tendrían peor pronóstico.

Leveduras nos tratos urinário e respiratório: infecção fúngica ou não? / Yeasts in the urinary and respiratory tracts: is it a fungal infection or not?

O início da década de 1980 foi marcado pela emergência das infecções fúngicas hospitalares, principalmente em pacientes imunocomprometidos, resultando em graves problemas de saúde. As leveduras do gênero Candida estão entre os principais agentes desse cenário. Entretanto, as espécies não-albicans surgem não só como colonizadores, mas como patógenos responsáveis por graves infecções. Os tratos urinário (TU) e respiratório (TR) são sítios anatômicos colonizados por esses microrganismos, os quais também são susceptíveis a infecções, podendo haver disseminação hematogênica. Contudo, ainda existem controvérsias sobre a conduta mediante um achado laboratorial de leveduras nas amostras oriundas da urina ou do TR, visto que os critérios utilizados para o diagnóstico de micoses nesses sítios não estão bem estabelecidos. O objetivo deste trabalho foi abordar os aspectos referentes às dificuldades na valorização dos achados de leveduras em amostras provenientes do TU e do TR em pacientes hospitalares, além do seu envolvimento nos processos de infecções invasivas.

The beginning of 80s was noticeable by hospital fungal infections, mainly in immunocompromised patients, resulting in serious health problems. Yeasts from Candida genus are among the most important agents of these infections. However, non-albicans species appear not only as colonizers, but also as pathogens responsible for severe infections. The urinary and the respiratory tracts are anatomical sites colonized by these microorganisms and they are susceptible to infections, which may cause hematogenic dissemination. Nevertheless, there are some controversies about the medical approach towards laboratory yeast findings in samples from the urine or respiratory tract, as the criteria used for the mycoses diagnosis in these sites are still not well established. The objective of this study was to discuss the aspects related to the difficulties in evaluating yeast findings in samples from the urinary and respiratory tracts in hospitalized patients, and also their involvement in invasive infection processes.

Cerebral Candida abscess in an infant.

Brain abscess is uncommon in the pediatric population. Here, we report one such case due to Candida albicans in one-year-old infant, without any predisposing factors. The child presented with progressively increasing size of head circumference. The diagnosis was confirmed by CT scan of brain and microbiological investigations on the drained pus material. The patient responded to combination of surgery (drainage) and intravenous amphotericin B. Neurological development six months after hospital discharge was normal. The organism being a rare cause of cerebral abscess in pediatric population is reported here.

Congenital tuberculosis with candidal sepsis in a neonate.

About 300 cases of congenital tuberculosis have been reported in the world literature, nevertheless rarely with nonspecific clinical manifestations. Here, we report the case of a premature infant with congenital tuberculosis and septicemia due to Candida krusei, who was treated successfully.

Thoracic empyema due to Candida albicans.

Few cases of empyema thoracis due to Candida species have been reported from the world and India. A 46-year-old male with esophageal carcinoma, who had taken radiotherapy, presented with fever and dyspnea. The chest X-ray showed findings suggestive of empyema. The diagnosis was confirmed by culturing Candida albicans from aspirated fluid and blood culture. The patient responded to antifungal treatment. High index of suspicion is required to diagnose such rare cases.

[ prevalence of central papillary atrophy in volunteer students of Kerman university of medical sciences [2006]]

Median rhomboid glossitis [MRG] or central papillary atrophy is an uncommon benign abnormality of the tongue, most frequently affecting men and it is believed that candidacies is the major etiologic factor for this abnormality. The purpose of this study was to investigate the prevalence of MRG and its characteristics in 837 students in Kerman University of Medical Sciences. In this research, 837 Medical Sciences students in 2006 were selected by census sampling and enrolled into the study. Oral examinations were performed in classes, wards and dormitories. All characteristics of subjects were recorded in a researcher-mode form and in those who had MRG based on clinical diagnosis, a sample was taken by swab and sent to the laboratory for candidiasis infection [hypha]. Data were analyzed by SPSS 13.5 and using t-test and chi2 test. The results showed that the prevalence of MRG is about 1.5% [13 cases]. There was a relationship between MRG and sex, but there was no relation between MRG and age. In 11 cases [84.6%] the smears were positive for candidiasis infection [hypha]. Based on previous published studies in the past and the present study, candidiasis infection [hypha] is a main factor for MRG. Therefore, in the cases of having median rhomboid glossitis, all causing factors for candidiasis should be examined and removed

Ocular lesions in disseminated candidiasis.

AIM: To assess the prevalence and patterns of ocular involvement in disseminated candidiasis in intensive care setting. MATERIALS AND METHODS: Institutional review board approved case review of intensive care admissions. These were patients of septicemia who had undergone ocular examination as part of their initial assessment. The records of patients in whom Candida spp. was detected in two sites or had a clinical diagnosis of candidemia were analyzed. RESULTS: Twelve patients (nine male, three female) were diagnosed with candida-induced sepsis during this period. Their ages ranged from 26 to 97 years (mean 52.7 years). Six patients (50%) had ocular lesions. The commonest lesion was chorioretinitis, seen in seven eyes of six patients followed by Roth spots seen in one eye. There was no evidence of vitritis or endophthalmitis in any eye. Systemic immunosuppression was present in three of six (50%) patients with ocular changes. Incidental findings included two eyes with non-proliferative diabetic retinopathy. CONCLUSIONS: Any suspicion of disseminated candidiasis should prompt an ocular evaluation which may help in the early diagnosis and in the institution of early antifungal therapy. This may reduce ocular morbidity and patient morbidity.

Greater severity and extent of periodontal breakdown in 136 south Indian human immunodeficiency virus seropositive patients than in normal controls: a comparative study using community periodontal index of treatment needs.

Apart from the more or less distinctive forms of periodontal disease associated with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome there remains considerable uncertainty as to whether or not conventional destructive periodontitis is exacerbated in HIV positive individuals. This is especially so in developing countries, from which few studies have been reported. The present study compared the severity and extent of periodontal break down in 136 HIV positive individuals from Chennai, South India, with 136 age-matched controls from the same low socio-economic and ethnic group. All surfaces of all teeth were scored for the community periodontal index of treatment needs (CPITN). Statistical analysis was performed using SPSS package. The results of the present study show that CPITN is a simple, useful technique to assess periodontal status in immunosuppressed patients and that periodontitis is associated with immunosuppression and oral candidiasis. The assessment of periodontal statuscould thus be a useful tool in minimally invasive screening of populations for HIV disease, especially in those parts of the world, like India and Africa, with high prevalence and rising incidence.

Non-healing gastric ulcer associated with Candida infection.

Candida bezoars of the stomach usually occur after gastric surgery. We report a small Candida mass occurring on a non-healing gastric ulcer in a 40-year-old male non-smoker. The ulcer healed with fluconazole and withdrawal of the proton pump inhibitor.
