Introduction COVID-19 vaccines have been highly effective in reducing morbidity and mortality during the pandemic. However, the emergence of the Omicron (B.1.1.529) variant and subvariants as the globally dominant strains have raised doubts about the effectiveness of currently-available vaccines and prompted debate about potential future vaccination strategies. Areas covered Using the publicly available IVAC VIEW-hub platform, we reviewed 52 studies on vaccine effectiveness (VE) after booster vaccinations. VE data were reported for SARS-CoV-2 symptomatic infection, severe disease and death and stratified by vaccine schedule and age. In addition, a non-systematic literature review of safety was performed to identify single or multi-country studies investigating adverse event rates for at least two of the currently-available COVID-19 vaccines. Expert opinion Booster shots of the current COVID-19 vaccines provide consistently high protection against Omicron-related severe disease and death. Additionally, this protection appears to be conserved for at least 3 months, with a small but significant waning after that time. The positive risk-benefit ratio of these vaccines is well established, thus increasing confidence in administering additional doses as required. Future vaccination strategies will likely include a combination of schedules based on a person’s risk profile, as overly frequent boosting may be neither beneficial nor sustainable for the general population.

The association between cardiac rhabdomyoma and intraventricular tumors and/or subcortical nodules is characteristic of tuberous sclerosis complex (TSC). Patients with TSC may have refractory seizures, autistic behavior, and cognitive decline. The patient received the fetal diagnosis of TSC at the age of 19 weeks of gestations, where presented at prenatal ultrasound cardiac and brain tumors. Fetal MRI showed a lesion in the right and left lateral ventricles near the foramen of Monro associated with subependymal lesions along the entire ependyma of the lateral ventricles and several subcortical tubercles, and the fetal Doppler echocardiogram revealed three cardiac lesions. The fetus underwent intrauterine treatment with everolimus and presented regression and subsequent stabilization of the cardiac and brain lesions; additionally, the patient did not develop seizures or autism and presented good neuropsychomotor development. It is the first evidence that mTOR inhibitors may help to prevent neurological complications associated with TSC.

Background There are few reports of miscarriages or stillbirths in women infected with SARS-CoV-2. We present five consecutive cases of fetal death (≥12 weeks) without other putative causes in women with laboratory-confirmed (RT-PCR) COVID-19 managed in a single Brazilian institution. Case series All five women were outpatients with mild or moderate forms of COVID-19 and were not taking any medication. Four were nulliparous, all were overweight or obese, and none had any comorbidities or pregnancy complications that could contribute to fetal demise. Fetal death occurred at 21–38 weeks of gestation, on COVID-days 1–22. SARS-Cov-2 was detected by RT-PCR in amniotic fluid in one case and in placental specimens in two cases. All five women had acute chorioamnionitis on placental histology, massive deposition of fibrin, mixed intervillitis/villitis, and intense neutrophil and lymphocyte infiltration. One fetus had neutrophils inside alveolar spaces, suggestive of fetal infection. Conclusions These five cases of fetal demise in women with confirmed COVID-19 without any other significant clinical or obstetric disorders suggest that fetal death can be an outcome of SARS-CoV-2 infection in pregnancy. The intense placental inflammatory reaction in all five cases raises the possibility of a direct effect of SARS-CoV-2 on the placenta., Highlights • There are few reports of stillbirth in women with COVID-19. • We describe 5 fetal deaths at 21–38 weeks of gestation. • All had acute chorioamnionitis on placental histology. • SARS-CoV-2 was detected in the amniotic fluid in one case and in the placenta in two cases. • SARS-CoV-2 may produce placental infection.

The majority of coronavirus disease 2019 (COVID-19) have been confirmed in adults, with only a few reported cases in children. In the pediatric population, COVID-19 infection appears to be often unremarkable or associated with mild respiratory symptoms. Little is known about neurologic complications related to COVID-19 in newborns. We present a case of severe encephalitis with cytotoxic brain edema in a newborn with COVID-19.

Background In Brazil, we are facing an alarming epidemic scenario of Yellow fever (YF), which is reaching the most populous areas of the country in unvaccinated people. Vaccination is the only effective tool to prevent YF. In special situations, such as patients with chronic immune-mediated inflammatory diseases (CIMID), undergoing immunosuppressive therapy, as a higher risk of severe adverse events may occur, assessment of the risk-benefit ratio of the yellow fever vaccine (YFV) should be performed on an individual level. Main body of the abstract Faced with the scarcity of specific orientation on YFV for this special group of patients, the Brazilian Rheumatology Society (BRS) endorsed a project aiming the development of individualized YFV recommendations for patients with CIMID, guided by questions addressed by both medical professionals and patients, followed an internationally validated methodology (GIN-McMaster Guideline Development). Firstly, a systematic review was carried out and an expert panel formed to take part of the decision process, comprising BRS clinical practitioners, as well as individuals from the Brazilian Dermatology Society (BDS), Brazilian Inflammatory Bowel Diseases Study Group (GEDIIB), and specialists on infectious diseases and vaccination (from Tropical Medicine, Infectious Diseases and Immunizations National Societies); in addition, two representatives of patient groups were included as members of the panel. When the quality of the evidence was low or there was a lack of evidence to determine the recommendations, the decisions were based on the expert opinion panel and a Delphi approach was performed. A recommendation was accepted upon achieving ≥80% agreement among the panel, including the patient representatives. As a result, eight recommendations were developed regarding the safety of YFV in patients with CIMID, considering the immunosuppression degree conferred by the treatment used. It was not possible to establish recommendations on the effectiveness of YFV in these patients as there is no consistent evidence to support these recommendations. Conclusion This paper approaches a real need, assessed by clinicians and patient care groups, to address specific questions on the management of YFV in patients with CIMID living or traveling to YF endemic areas, involving specialists from many areas together with patients, and might have global applicability, contributing to and supporting vaccination practices. We recommended a shared decision-making approach on taking or not the YFV.

Background: Following the first reports of the emergence of methicillin-resistant Staphylococcus aureus (MRSA) in the 1970s, several measures to prevent its transmission were introduced in hospitals. However, controversy continues regarding the best approach to prevent and control MRSA, especially in neonatal intensive care units (NICUs). Objective: To report the reduction of colonization and primary central venous catheter–related bloodstream infection (CRBSI) caused by MRSA through surveillance, decolonization, and adoption of best practices in intravenous catheter care. Methods: Quasi-experimental, nonrandomized, before-and-after intervention study conducted in a 70-bed NICU in a private maternity hospital in Brazil. Period studied comprehended between August 2018 and May 2019 (period 1 - preintervention) and June to December 2019 (period II - postintervention). At the end of period 1, several measures were implanted to control and prevent colonization and CRBSI in the unit. The following measures were implemented: incentive to hand hygiene; best practices training on medication preparation and central catheter manipulation; systematic screening of colonized patients with nasal and umbilical swabs; contact precautions for colonized newborn (NB); contact precautions for twins of a colonized NB even when they had a negative swab; decolonization of patients with nasal mupirocin and chlorohexidine (oral preparation) for oral hygiene; concurrent linen change at the end of the patient’s decolonization; decolonization of parents of colonized siblings with chlorohexidine bath and nasal mupirocin; environmental organization; intensification of cleaning and disinfection of equipment and articles; cohort of patients and workers; isolation and precautions compliance audit; professional investigation and decolonization and universal chlorhexidine bath for newborns. Results: In periods I and II, the positivity rates of the collected swabs were 4.14% and 0.75% (P < .0001), respectively, with a peak of positivity of 11.8% in January. Also, 12 episodes of CRBSI were documented in period I (incidence, 2.9%) versus no episode in period 2, with a significant difference in incidence rate between the 2 periods (P = .002). Conclusion: The innovative measures were effective for eradicating the outbreak when instituted together with recognized good practices. In an outbreak scenario is difficult to define the isolated impact of each measure, although, parents’ decolonization to prevent the colonization of other siblings and contact precautions for twins of colonized NB seemed to improve the results.Funding: NoneDisclosures: None

The most commonly identified pathogens related to bacterial meningitis are group B streptococcus and gram-negative enteric flora; anaerobic sepsis and meningitis are very rare. We report a case on a preterm and extremely low-birth weight infant who developed meningitis caused by Bacteroides fragilis and his mother who had postpartum sepsis also caused by the same agent.

BACKGROUND: Group B streptococcus (GBS) is one of the principal agents of neonatal early onset sepsis (EOS). OBJECTIVE: To evaluate the incidence of GBS colonization and neonatal EOS due to GBS and to describe the compliance of an institutional protocol. METHODS: From January 2007 to December 2010 we conducted a retrospective cohort study to evaluate the incidence of maternal GBS colonization in high risk pregnant women. A protocol was implemented to determine anal/vaginal GBS colonization of all women at 22 to 37 weeks of pregnancy and all patients that presented the following risk factors. Intrapartum antibiotic prophylaxis (IAP) was administered according to the Centers for Disease Control and Prevention (CDC) guidelines. From January 2009 to December 2010, data from the medical records of all newborns at the NICU were also collected to identify the incidence of newborns whose mothers were screened as indicated by the protocol. RESULTS: A total of 4,797 high risk pregnant women were included. The incidence of maternal GBS colonization was 23%. The incidence of neonatal EOS due to GBS was 0.09/1000 live births and a 50% mortality rate. Information regarding GBS maternal colonization was available for 91% of the neonates admitted to the NICU. CONCLUSIONS: The maternal GBS colonization rate was similar to that described in the literature. Information regarding maternal GBS colonization was available to the majority of neonates, which is essential for management of this high risk population. The strategy of surveillance of high risk pregnant women can provide a useful and feasible strategy.

No. of bitstreams: 0 Previous issue date: 2016 Foundation to Fight against Nosocomial Infections Background: There are no data on surgical site infection (SSI) rates stratified by surgical procedures (SPs) in Brazil, and our objective was to report such rates. Methods: From January 2005 to December 2010 we conducted a surveillance study on SSIs in four hospital members of the International Nosocomial Infection Control Consortium (INICC) in four Brazilian cities. We applied the U.S. Centers for Disease Control and Prevention's National Healthcare Safety Network's (CDC-NHSN's) surveillance methods. Surgical procedures were classified into following types following International Classification of Diseases (ICD-9) criteria. Results: We recorded 349 SSIs, associated to 61,863 SPs (0.6%; [CI], 0.5-0.6). SSI rates per type of SP were compared with INICC and CDC-NHSN reports, respectively: 2.9% for cardiac surgery (vs. 5.6%, p=0.001 vs. 1.3%, p=0.001); 0.4% for cesarean section (vs. 0.7%, p=0.001 vs. 1.8%, p=0.001); 5.4% for craniotomy (vs. 4.4% p=0.447 vs. 2.6% p=0.005) and 1.1% for vaginal hysterectomy (vs. 2.0% p=0.102 vs. 0.9% p=0.499.) Conclusions: Our SSI rates were greater in two of the four analyzed types of SPs compared with CDC-NHSN, but similar to most INICC rates. These findings on the epidemiology of SSI in Brazil will enable us to introduce targeted interventions for infection control.

To review the current state of development of streptococcus B, herpes-zoster, HIV, malaria and dengue vaccines. These vaccines were selected both because of imminent commercial release and because of specific problems with their development. A review of the literature was performed by means of a MEDLINE search, on the period 1996 to 2006, for the epidemiology and immunology of these diseases, analyzing both the greatest obstacles to creating a vaccine and the current state of research, with emphasis on studies in the most advanced stages. Each of the five diseases chosen presents specific problems for vaccine development. Nevertheless, in the majority of cases these have been or are in sight of being resolved, allowing for the prediction that a safe and effective vaccine - or vaccines - will be available in the near future. Despite the problems faced in developing these vaccines, advances in molecular biology and immunology have made it possible to overcome most obstacles, opening up the prospects for new vaccines.

Objective:To describe the epidemiology of healthcare-associated infections (HAIs) among neonates.Design:Prospective surveillance of HAIs was conducted during 2 years. Infections beginning within 48 hours of birth were defined as HAIs of maternal origin. Death occurring during an active episode of HAI was considered related to HAI.Setting:Seven neonatal units located in three Brazilian cities.Patients:All admitted neonates were included and observed until discharge.Results:Twenty-two percent of 4,878 neonates had at least one HAI. The overall incidence density was 24.9 per 1,000 patient-days, and 28.1% of all HAIs were maternally acquired. HAI rates ranged from 12.3% in the group with a birth weight (BW) of more than 2,500 g to 51.9% in the group with a BW of 1,000 g or less. The main HAIs were bloodstream infection (BSI) and pneumonia. Coagulase-negative staphylococci,Enterobacterspecies,Staphylococcus aureus,andKlebsiella pneumoniaewere the main pathogens. Forty percent of all deaths were related to HAI. Central venous catheter (CVC)-associated BSIs per 1,000 CVC-days ranged from 17.3 (BW, 1,501 to 2,500 g; device utilization [DU], 0.11) to 34.9 (BW, ≤ 1,000 g; DU, 34.92). Ventilator-associated pneumonia per 1,000 ventilator-days ranged from 7.0 (BW, ≤ 1,000 g; DU, 0.34) to 9.2 (BW, 1,001 to 1,500 g; DU, 0.14).Conclusions:The high proportion of HAIs of maternal origin highlights perinatal care issues in Brazil and the need to improve the diagnosis of neonatal HAIs. The very low BW group and device-associated infections should be priorities for prevention strategies in this population.

During the 6-year study using the Centers for Disease Control and Prevention's (CDC) U.S. National Healthcare Safety Network (NHSN) definitions for device-associated health care-associated infection (DA-HAI), we collected prospective data from 605,310 patients hospitalized in the INICC's ICUs for an aggregate of 3,338,396 days. Although device utilization in the INICC's ICUs was similar to that reported from ICUs in the U.S. in the CDC's NHSN, rates of device-associated nosocomial infection were higher in the ICUs of the INICC hospitals: the pooled rate of central line-associated bloodstream infection in the INICC's ICUs, 4.9 per 1,000 central line days, is nearly 5-fold higher than the 0.9 per 1,000 central line days reported from comparable U. S. ICUs. The overall rate of ventilator-associated pneumonia was also higher (16.8 vs 1.1 per 1,000 ventilator days) as was the rate of catheter-associated urinary tract infection (5.5 vs 1.3 per 1,000 catheter days). Frequencies of resistance of Pseudomonas isolates to amikacin (42.8% vs 10%) and imipenem (42.4% vs 26.1%) and Klebsiella pneumoniae isolates to ceftazidime (71.2% vs 28.8%) and imipenem (19.6% vs 12.8%) were also higher in the INICC's ICUs compared with the ICUs of the CDC's NHSN.

Staphylococcus aureus colonization is a risk factor for endogenous staphylococcal infection in vulnerable neonates. Several studies describe prophylactic measures for adult population, but very few recommendations are establish for neonatal intensive care unit (NICU). After detecting an increase in severe S. aureus infection in the NICU, the present study has the objective to check if a bundle of measures to decrease S aureus colonization in NICU babies have impact in reducing infection.

OBJETIVO: Descrever a cobertura vacinal de gestantes para influenza e fatores associados à recusa ou à aceitação da vacina. MÉTODOS: Estudo descritivo, prospectivo, que incluiu 300 puérperas atendidas no Hospital e Maternidade Santa Joana (SP). Os dados foram coletados em outubro de 2010, por meio de questionário pré-testado, aplicado por profissional treinado. RESULTADOS: A média de idade das mães foi 30,5 anos; 231 (77%) eram casadas; 164 (54,7%) primigestas; 192 (64%) tinham nível superior de escolaridade; e 240 (80%) estavam empregadas. Durante o pré-natal, 234 (78%) receberam informação sobre a vacina contra influenza e 287 (95,7%) foram imunizadas; 210 (73,2%) mulheres tinham conhecimento sobre a proteção neonatal pela vacinação materna. Fatores associados à aceitação foram: campanha do governo (133; 44,3%) e recomendação médica durante o pré-natal (163; 54,3%). Entre as 13 grávidas que recusaram a vacinação, as razões foram: negligência (4), falta de tempo (4), falta de indicação médica (3) ou contraindicação pelo médico (2), mas 69,2% teriam sido vacinadas se tivessem sido informadas sobre a proteção neonatal. CONCLUSÃO: O receio da pandemia e a campanha pública tiveram importante impacto na elevada cobertura vacinal para influenza em gestantes. Recomendação médica e campanha do governo foram os principais motivos de aceitação da vacina. OBJECTIVES: To describe the immunization coverage of the influenza vaccine for pregnant women, and factors associated to vaccination compliance. METHODS: This is a prospective, descriptive study including 300 women who had just given birth at Hospital and Maternity Santa Joana in Sao Paulo, Brazil. Data were collected through a pre-tested questionnaire applied by a trained evaluator during October 2010. RESULTS: The mean age of mothers was 30.5 years; 231 (77%) were married; 164 (54.7%) were primigravidas; 192 (64%) had higher education; and 240 (80%) were employed. During the prenatal period, 234 (78%) received information about the influenza vaccine and 287 (95.7%) were immunized; 210 (73.2%) women knew about neonatal protection achieved through maternal vaccination. The factors associated with maternal acceptance of the vaccine were government campaign (133; 44.3%), and medical recommendation during prenatal visits (163; 54.3%). A total of 13 pregnant women refused vaccination for the following reasons: neglect (4), lack of time (4), lack of recommendation from their physician (3) or contraindication by physician (2), but 69.2% of them would have accepted immunization had they been informed about neonatal protection. CONCLUSIONS: The fear of a pandemic and the public vaccination campaign had an important impact on the high immunization coverage for influenza on pregnant women. Medical recommendation and the government campaign were the main reasons for vaccine compliance.

The objective of this study was to characterize the immune response of children after the use of two different vaccine doses and to evaluate whether vaccination benefits children attending day care centers in areas with high anti-HAV seroprevalence. The study was conducted in a day care center with a stable population in Sao Paulo, Brazil. Two groups of 20 children, all seronegative for hepatitis A antibodies, were assigned randomly to receive three times 0.5 and 1.0 ml of the vaccine, the second and third dose 1 and 6 months after the first dose, respectively. There were 27 children in the control group. All children in both vaccinated groups had protective levels of antibodies in the serum after two inoculations, and serious adverse reactions were not observed. In the eighth month of follow-up, a hepatitis A outbreak occurred in the day care center. Five children in the control group had high titers of IgM class anti-HAV, four with clinical manifestations of acute hepatitis. None of the vaccinated children developed symptoms or signs of hepatitis (P = 0.0125), and the estimate of vaccine efficacy was 100%. Two nonstudy children from the center also had clinical and serological evidence of acute hepatitis A. It is concluded that vaccination represents an important method for prevention of hepatitis A transmission in day care centers. The results of this pilot study justify further testing in larger groups.

Background The occurrence of a respiratory syncytial virus (RSV) outbreak in a Neonatal Intensive Care Unit (NICU) is related to unfavorable outcomes, as this infection can lead to respiratory distress and death in premature in infants. Report the successful control of an outbreak that occurred in April 2010 in a NICU. Methods After the index case, of 18 premature infants placed in the same room 10 infants were infected. Of those 10, 6 developed mild to moderate respiratory symptoms, 4 persisted asymptomatic and no death occurred. Contact and respiratory precautions were rapidly initiated, the infants were cohorted in 3 different rooms and palivizumab was administered to all contacts. Results The outbreak was controlled and no new cases were subsequently indentified. Conclusion Standard infection control measures plus palivizumab prophylaxis were efficient in rapid control of the outbreak.

WOS: 000296843100008 PubMed: 21732120 Purpose To evaluate the impact of country socioeconomic status and hospital type on device-associated healthcare-associated infections (DA-HAIs) in neonatal intensive care units (NICUs). Methods Data were collected on DA-HAIs from September 2003 to February 2010 on 13,251 patients in 30 NICUs in 15 countries. DA-HAIs were defined using criteria formulated by the Centers for Disease Control and Prevention. Country socioeconomic status was defined using World Bank criteria. Results Central-line-associated bloodstream infection (CLA-BSI) rates in NICU patients were significantly lower in private than academic hospitals (10.8 vs. 14.3 CLA-BSI per 1,000 catheter-days; p < 0.03), but not different in public and academic hospitals (14.6 vs. 14.3 CLA-BSI per 1,000 catheter-days; p = 0.86). NICU patient CLA-BSI rates were significantly higher in low-income countries than in lower-middle-income countries or upper-middle-income countries [37.0 vs. 11.9 (p < 0.02) vs. 17.6 (p < 0.05) CLA-BSIs per 1,000 catheter-days, respectively]. Ventilator-associated-pneumonia (VAP) rates in NICU patients were significantly higher in academic hospitals than in private or public hospitals [13.2 vs. 2.4 (p < 0.001) vs. 4.9 (p < 0.001) VAPs per 1,000 ventilator days, respectively]. Lower-middle-income countries had significantly higher VAP rates than low-income countries (11.8 vs. 3.8 per 1,000 ventilator-days; p < 0.001), but VAP rates were not different in low-income countries and upper-middle-income countries (3.8 vs. 6.7 per 1,000 ventilator-days; p = 0.57). When examined by hospital type, overall crude mortality for NICU patients without DA-HAIs was significantly higher in academic and public hospitals than in private hospitals (5.8 vs. 12.5%; p < 0.001). In contrast, NICU patient mortality among those with DA-HAIs was not different regardless of hospital type or country socioeconomic level. Conclusions Hospital type and country socioeconomic level influence DA-HAI rates and overall mortality in developing countries.

Hand hygiene (HH) is the most important strategy to reduce healthcare associated infection. Central line associated bloodstream infection (CLABSI) is the most frequent and severe infection in the Neonatal intensive care unit (NICU).

Group B Streptococcus (GBS) is the main etiological agent of neonatal sepsis in developed countries, however there is no detailed information on its incidence in Brazil. We registered the incidence and lethality of GBS infection in a Brazilian private maternity hospital from April 1991 to March 2000. Maternal risk factors contributing to neonatal infections were also scored. The rate of infection was determined by checking for GBS in the blood and liquor of symptomatic neonates within 72 hours of birth. Sepsis and/or early onset meningitis were diagnosed in 43 neonates (32 cases in blood, 1in liquor and 10 in blood and liquor). The overall incidence was 0.39 per thousand neonates and remained quite constant throughout the period, ranging from 0.25-0.63. Septic shock occurred in 33 neonates within 1 to 36 hours of birth (mean 15 hours). Among those patients, 26 (60%) died between the 5th and the 85th hour after birth. Maternal risk factors, according to CDC criteria, included: gestational age below 37 weeks in 26 cases (60%), amniorrhexis equal or superior to 18 hours in 7 cases (16%), and maternal temperature equal or superior to 38(o)C in 4 cases (9%). None of the mothers had received prophylactic antibiotics during labor nor were urine, rectal or vaginal swabs screened for GBS. Although the incidence of GBS infection in the population in this study was lower than that found in developed countries, its rate of mortality was higher. The death rate could be reduced through recognition of the risk factors and prophylactic antibiotics during labor.

In order to evaluate the epidemiology of candidemia in Brazil, we performed a prospective multicenter study conducted in six general hospitals from Sao Paulo and Rio de Janeiro. We enrolled a total of 145 candidemic patients (85 males) with a median age of 32 years. Non-albicans species accounted for 63% of all episodes and the species most frequently causing candidemia were C. albicans (37%), C. parapsilosis (25%), C. tropicalis (24%), C. rugosa (5%), and C. glabrata (4%). Systemic azoles were used before the onset of candidemia in only six patients. There were no differences in the coexisting exposures or underlying diseases associated with the species most frequently causing candidemia. The overall crude mortality rate was 50%. Nosocomial candidemias in our tertiary hospitals are caused predominantly by non-albicans species, which are rarely fluconazole resistant. This predominance of non-albicans species could not be related to the previous use of azoles.

Scabies epidemics are not unusual, and the recommended way of stopping them is by simultaneous treatment of everybody in the facility; this has been known since the last century, when Norwegian scabies was a problem in Norway. When this is not done, scabies epidemics can smolder for months. Scabies should not spread with good infection control measures, but we learned that a good infection control service is not enough. Efforts have to be done to educate everybody in the hospital, including laundry workers, and to improve work conditions.

Candida infections account for 80% of all fungal infections in the hospital environment, including bloodstream, urinary tract and surgical site infections. Bloodstream infections are now a major challenge for tertiary hospitals worldwide due to their high prevalence and mortality rates. The incidence of candidemia in tertiary public hospitals in Brazil is approximately 2.5 cases per 1000 hospital admissions. Due to the importance of this infection, the authors provide a review of the diversity of the genus Candida and its clinical relevance, the therapeutic options and discuss the treatment of major infections caused by Candida. Each topography is discussed with regard to epidemiological, clinical and laboratory diagnostic and therapeutic recommendations based on levels of evidence.

Objective:To analyze possible risk factors for death among patients with nosocomial candidemia. To identify risk factors for death in patients with candidemia, we analyzed demographic, clinical, and microbiological data.Setting:Six tertiary hospitals in Brazil.Patients:A cohort of 145 patients with candidemia.Design:26 possible risk factors for death, including age, underlying disease, signs of deep-seated infection, neutropenia, number of positive blood cultures, removal of a central venous catheter, etiologic agent of the candidemia, susceptibility pattern of the isolate to amphotericin B, and antifungal treatment were evaluated by univariate stepwise logistic regression analysis.Results:Non-albicans species accounted for 63.4% of the candidemias. Risk factors for death in univariate analysis were older age, catheter retention, poor performance status, candidemia due to species other than Candida parapsilosis, hypotension, candidemia due to species other than Candida parapsilosis, and no antifungal treatment. In multivariate analysis, older age and non-removal of a central venous catheter were the only factors associated with an increased risk for death.Conclusions:These data suggest that patients with candidemia and a central venous catheter should have the catheter removed.
