RESUMO

BACKGROUND: Data on the characteristics of acute kidney injury (AKI) in pediatric COVID-19 and MIS-C are limited. We aimed to define the frequency, associated factors and early outcome of AKI in moderate, severe or critical COVID-19 and MIS-C; and to present a tertiary referral center experience from Türkiye. METHODS: Hospitalized patients ≤ 18 years of age with confirmed COVID-19 or MIS-C at Ihsan Dogramaci Children's Hospital, Hacettepe University, between March 2020-December 2021 were enrolled. The characteristics of AKI in the COVID-19 group were investigated in moderate, severe and critically ill patients; patients with mild COVID-19 were excluded. RESULTS: The median (Q1-Q3) age in the COVID-19 (n = 66) and MIS-C (n = 111) groups was 10.7 years (3.9-15.2) and 8.7 years (4.5-12.7), respectively. The frequency of AKI was 22.7% (15/66) in COVID-19 and 15.3% (17/111) in MIS-C; all MIS-C patients with AKI and 73.3% (11/15) of COVID-19 patients with AKI had AKI at the time of admission. Multivariate analyses revealed need for vasoactive/inotropic agents [Odds ratio (OR) 19.233, p = 0.002] and presence of vomiting and/or diarrhea (OR 4.465, p = 0.036) as independent risk factors of AKI in COVID-19 patients; and need for vasoactive/inotropic agents (OR 22.542, p = 0.020), procalcitonin and ferritin levels as independent risk factors of AKI in the MIS-C group. Age was correlated with lymphocyte count (r = -0.513, p < 0.001) and troponin level (r = 0.518, p < 0.001) in MIS-C patients. Length of hospital stay was significantly longer in both groups with AKI, compared to those without AKI. Mortality was 9.1% in the COVID-19 group; and was associated with AKI (p = 0.021). There was no mortality in MIS-C patients. AKI recovery at discharge was 63.6% in COVID-19 survivors and 100% in MIS-C patients. CONCLUSIONS: Independent risk factors for AKI were need for vasoactive/inotropic agents and vomiting/diarrhea in moderate, severe or critical COVID-19 patients; and need for vasoactive/inotropic agents and severe inflammation in MIS-C patients. Our findings suggest that inflammation and cardiac dysfunction are associated with AKI in MIS-C patients; and the association with age in this group merits further studies in larger groups. Early outcome is favorable; long-term follow-up for kidney functions is needed.

RESUMO

Crimean-Congo hemorrhagic fever (CCHF), endemic in certain regions of the world, is listed as a priority disease with pandemic potential. Since CCHF was first identified in Turkey, children have been known to experience milder disease than adults. However, during the COVID-19 pandemic, we observed an unusually severe disease course, including hemophagocytic lymphohistiocytosis (HLH). We examined cytokine/chemokine profiles of 9/12 case-patients compared with healthy controls at 3 time intervals. Interferon pathway-related cytokines/chemokines, including interleukin (IL) 18, macrophage inflammatory protein 3α, and IL-33, were elevated, but tumor necrosis factor-α, IL-6, CXCL8 (formerly IL-8), and cytokines acting through C-C chemokine receptor 2 and CCR5 were lower among case-patients than controls. Interferon pathway activation and cytokines/chemokines acting through CCR2 and CCR5 improved health results among children with severe CCHF. Children can experience severe CCHF, including HLH, and HLH secondary to CCHF can be successfully treated with intravenous immunoglobulin and steroid therapy.

RESUMO

BACKGROUND: This study aimed to evaluate the effectiveness and optimal use of corticosteroids in children with severe coronavirus disease 2019 (COVID-19) pneumonia, for which effective treatment is still lacking with respect to this population. METHODS: We conducted a retrospective study and included patients (aged < 18 years) with severe COVID-19 pneumonia and/or acute respiratory distress syndrome (ARDS) who received standard doses (2-4 mg/kg/day) and high doses (>250 mg/day) of methylprednisolone (MPZ). We adjusted for patients on steroid treatments with a propensity score and compared the side effects of different MPZ doses and patient survival. RESULTS: Fifty-nine patients were included: 61% were male, the median age was 8, interquartile range (IQR) 2-15) years. The overall survival was 84.4% in patients treated with standard-dose MPZ (n = 45, 76.3%) and 92.2% in patients treated with high-dose MPZ (n = 14, 23.7%; p = 0.67). The demographic, clinical, and laboratory data did not differ significantly after propensity score matching, apart from bradycardia, which was a prominent feature of the high-dose group. The clinical and radiological response rates on day 7 were higher and the need for invasive mechanical ventilation (IMV) was lower in the high-dose group. CONCLUSION: The patients with high-dose MPZ had better clinical and radiological responses than those with standard-dose MPZ, although the mortality rate did not differ between standard and high-dose regimens of MPZ.

RESUMO

BACKGROUND: Coronavirus disease 19 (COVID-19) may have a severe course in children. Multisystem inflammatory syndrome in children (MIS-C) is the post-COVID complication characterized by an exaggerated inflammation, observed in children. However, data on the underlying pathophysiology are sparse. We therefore aimed to assess the cytokine and chemokine profiles of children with MIS-C and compare these to life-threatening severe SARS-CoV-2 and healthy controls (HCs) to shed light on disease pathophysiology. METHODS: Samples of 31 children with MIS-C, 10 with severe/critical COVID-19 and 11 HCs were included. Cytokine and chemokine profiles were studied and compared in between groups. RESULTS: Most cytokines and chemokines related to IL-1 family and IFN-γ pathway (including IL-18 and MIG/CXCL9) and IL-17A were significantly higher in the MIS-C group when compared to the severe/critical COVID-19 group and HCs. IP-10/CXCL10 and IL-10 were higher in both MIS-C patients and severe/critical COVID-19 compared to HCs. CONCLUSION: Our results suggest that IL-1 and IFN-γ pathways play an important role in the pathophysiology of MIS-C. IMPACT: This study defines a pattern of distinctive immune responses in children with MIS-C and in patients with severe/critical COVID-19. As the COVID-19 pandemic continues, biomarkers to identify MIS-C risk are needed to guide our management that study results may shed light on it.

RESUMO

INTRODUCTION: Although Kocher criteria can distinguish a septic hip from an aseptic cause, they may not apply to a septic knee. We aimed to identify predictors to discriminate septic and aseptic causes of acute knee monoarthritis in children who underwent arthrocentesis. METHODS: We conducted a retrospective cohort study among children who underwent arthrocentesis for suspected septic arthritis of the knee. Collected data included demographic, clinical and laboratory characteristics. We performed univariate and multivariable analyses to identify predictors of the septic knee. We further investigated accuracy of different predictive models. RESULTS: A total of 60 patients who underwent arthrocentesis for suspected knee septic arthritis were included in this study. Septic arthritis of the knee was confirmed in 32 (53%) patients. Age ≤ 5 years (OR 4.237, [95% CI 1.270-14.127], p = 0.019), WBC > 12,000 cells/mm3 (OR 5.059, [95% CI 1.424-17.970], p = 0.012), and CRP > 2 mg/dL (OR 3.180, [0.895-11.298], p = 0.074) were the most important predictors of a septic knee. Three-tier model comprising these three factors (AUC 0.766) and 4-tier model with addition of fever >38.5°C (AUC 0.776) performed better than Kocher criteria (AUC 0.677), modified Kocher criteria (AUC 0.699) and Full Model (adding age ≤ 5 years and CRP >2 mg/dL to Kocher criteria) (AUC 0.746). Full Model successfully ruled out septic arthritis if all 6 criteria were negative. CONCLUSION: Based on these findings, we propose an algorithm to identify low, intermediate and high-risk patients for knee septic arthritis. Our proposed two-step algorithm incorporating major (age, WBC, CRP) and minor (fever, ESR, non-weight bearing) criteria can serve as a simple decision-support tool to justify arthrocentesis in children with suspected knee septic arthritis.

RESUMO

Severity of disease caused by influenza virus and the influencing factors that may be different. Moreover, the disease course actually may not be determined specifically in children because of lower seroprotection rates of children. Herein, the results clinic and outcome data of children with influenza from Turkey were reported. We present here the results from 2013 to 2017. Nasopharyngeal swab samples of the children with influenza were investigated via multiplex polymerase chain reaction. A total of 348 children were diagnosed with influenza; 143 (41.1%) were influenza A, 85 (24.4%) were influenza B, and 120 (34.5%) were mixt infection with other respiratory viruses. Fifty-four percent of children admitted to intensive care unit (ICU) were under 2 years of age (p = .001). Having an underlying disease was detected as the main predictor for both hospitalization and ICU stay according to multiple logistic regression analysis (odds ratio [OR], 11.784: 95% confidence interval [CI], 5.212-26.643; p = .001 and OR, 4.972: 95% CI, 2.331-10.605; p = .001, respectively). Neurological symptoms most frequently seen in cases who died (44.4%; p = .02). Lymphopenia was relatively higher (55.6%) and thrombocytopenia was most frequently seen in cases who died (77.8%) with a significant ratio (p = .001). Underlying diseases was found a risk factor for influenza being hospitalized and being admitted to ICU. Children under 2 years of age and with underlying diseases should be vaccinated particularly in countries where the influenza vaccination is still not routinely implemented in the immunization schedule. Highlights Underlying diseases is a risk factor for influenza to be hospitalized and admitted to ICU. Influenza vaccination is of great importance to prevent life-threatening complications of influenza, particularly in children require ICU admission. The possibility to reduce the outpatient visit number by vaccination has a great impact on disease burden in addition to the underestimated crucial social benefits, as well.

RESUMO

The disease course of children with coronavirus disease 2019 (COVID-19) seems milder as compared with adults, however, actual reason of the pathogenesis still remains unclear. There is a growing interest on possible relationship between pathogenicity or disease severity and biomarkers including cytokines or chemokines. We wondered whether these biomarkers could be used for the prediction of the prognosis of COVID-19 and improving our understanding on the variations between pediatric and adult cases with COVID-19. The acute phase serum levels of 25 cytokines and chemokines in the serum samples from 60 COVID-19 pediatric (n = 30) and adult cases (n = 30) including 20 severe or critically ill, 25 moderate and 15 mild patients and 30 healthy pediatric (n = 15) and adult (n = 15) volunteers were measured using commercially available fluorescent bead immunoassay and analyzed in combination with clinical data. Interferon gamma-induced protein 10 (IP-10) and macrophage inflammatory protein (MIP)-3ß levels were significantly higher in patient cohort including pediatric and adult cases with COVID-19 when compared with all healthy volunteers (p ≤ .001 in each) and whereas IP-10 levels were significantly higher in both pediatric and adult cases with severe disease course, MIP-3ß were significantly lower in healthy controls. Additionally, IP-10 is an independent predictor for disease severity, particularly in children and interleukin-6 seems a relatively good predictor for disease severity in adults. IP-10 and MIP-3ß seem good research candidates to understand severity of COVID-19 in both pediatric and adult population and to investigate possible pathophysiological mechanism of COVID-19.

RESUMO

It is still not fully understood how to predict the future prognosis of patients at the diagnosis coronavirus disease 2019 (COVID-19) due to the wide clinical range of the disease. We aimed to evaluate whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral load could predict the clinical course of pediatric patients. This study was conducted retrospectively with medical records of pediatric patients who were tested for SARS-CoV2 between April 12 and October 25, 2020 in the University of Health Sciences, Ankara Educating and Training Hospital and Hacettepe University Faculty of Medicine. We evaluated 518 pediatric patients diagnosed with COVID-19 and classified according to severity as asymptomatic (16.2%), mild (59.6%), moderate (20.2%), and critical/severe (3.9%) cases. We analyzed patients in four groups in terms of ages: <4, 5-9, 10-14, and 15-17 years. There was no statistically significant difference in terms of ∆Ct value among age groups, different gender and the existence of underlying diseases in each disease course. The ∆Ct values were relatively lower in the first 2 days of symptoms than after days in all groups. Our study has indicated that children with COVID-19 have similar amount of viral load in all disease courses irrespective of the age and underlying disease. It should be taken into account that, regardless of the severity of the disease, pediatric patients may have a role in the transmission chain.

RESUMO

OBJECTIVE: Febrile neutropenia (FN) represents a life-threatening complication in hematological malignancies. We aimed to analyze the utility of soluble vascular cell adhesion molecule 1 (sVCAM-1), intercellular adhesion molecule 1 (sICAM-1), vascular endothelial growth factor (VEGF) levels compared with C-reactive protein (CRP) and procalcitonin (PCT) during febrile neutropenia episodes of pediatric patients with leukemia. METHODS: Two plasma samples, on day 0 (initial of episode) and day 3 (48-72 h after episode), for VCAM-1, ICAM-1 and VEGF, CRP and PCT were prospectively collected concomitantly during each febrile neutropenic episode between December 2016 and December 2017. The primary outcome was bacteremia and the secondary outcome was intensive care unit (ICU) admission. RESULTS: Twenty-two (28.6%) acute lymphoblastic lymphoma (ALL), seventeen (22.1%) acute myeloblastic lymphoma (AML) patients and thirty-eight (49.3%) control patients with no known underlying disease or fever were included in this study. Of the 39 patients; 16 (41%) had bacteremia. Mean serum sVCAM1 and sICAM1 levels were significantly higher in control group, compared to FN patients (p < 0.001). Mean serum sVCAM2 level was significantly higher in FN patients with bacteremia compared to FN patients without bacteremia (144.97 ± 70.35 pg/mL vs 85.45 ± 53.76 pg/mL, p = 0.022). Mean sVCAM1 and 2 levels were higher in FN patients with ICU admission. In this study, we found that sVCAM-1 and VEGF, when combined to CRP and PCT, could predict gram-negative bacteremia in FN episodes of pediatric hematological malignancy. CONCLUSION: Serum endothelial adhesion molecules, excluding sVCAM-1, cannot predict bacteremia and ICU admission alone in FN patients; but may be associated with clinical outcome when used with PCT and CRP.

RESUMO

Encephalitis is a serious neurological syndrome caused by inflammation of the brain. The diagnosis can be challenging and etiology remains unidentified in about half of the pediatric cases. We aimed to investigate demographic, clinical, laboratory, electroencephalographic and neuroimaging findings, and outcome of acute encephalitis of nonbacterial etiology. This prospective study included children hospitalized with the diagnosis of acute encephalitis between 2017 and 2019. Microbiological investigations of the cerebrospinal fluid (CSF) were recorded. All CSF specimens were tested for anti-N methyl D-aspartate receptor (NMDAR) antibodies. In total, 31 children aged 10 months to 17 years (median = 6 years) were included. Pathogens were confirmed in CSF in three patients (9.7%): varicella zoster virus, herpes simplex virus type 1 (HSV-1), and both HSV-1 and NMDAR antibodies. Presenting features included encephalopathy (100%), fever (80.6%), seizure (45.2%), focal neurological signs (29%), and ataxia (19.4%). On clinical follow-up of median 9 (6-24) months, six patients showed neurological deficits: together with two patients who died in hospital, total eight (25.8%) patients were considered to have unfavorable outcome. Need for intubation, receiving immunomodulatory treatment, prolonged hospitalization, and high erythrocyte sedimentation rate at admission were associated with unfavorable outcome. The etiology of encephalitis remains unexplained in the majority of children. HSV-1 is the most frequently detected virus, consistent with the literature. The fact that anti-NMDAR encephalitis was detected in one child suggests autoimmune encephalitis not being rare in our center. The outcome is favorable in the majority while about one-fifth of cases suffer from sequelae.

RESUMO

BACKGROUND: The rising number of infections due to Severe Acute Respiratory Syndrome Coronavirus-2 (popularly known as COVID-19) has brought to the fore new antiviral drugs as possible treatments, including favipiravir. However, there is currently no data regarding the safety of this drug in patients with kidney impairment. The aim of this paper, therefore, is to share our experience of the use of favipiravir in pediatric patients affected by COVID-19 with any degree of kidney impairment. METHODS: The study enrolled pediatric patients aged under 18 years and confirmed as suffering from COVID-19 and multisystem inflammatory syndrome in children (MIS-C) with any degree of kidney injury, who were treated with favipiravir at the time of admission. RESULTS: Out of a total of 11 patients, 7 were diagnosed with MIS-C and 4 with severe COVID-19. The median age of the cases was 15.45 (9-17.8) years and the male/female ratio was 7/4. At the time of admission, the median serum creatinine level was 1.1 mg/dl. Nine patients were treated with favipiravir for 5 days, and 2 patients for 5 days followed by remdesivir for 5-10 days despite kidney injury at the time of admission. Seven patients underwent plasma exchange for MIS-C while 2 severely affected cases underwent continuous kidney replacement therapy (CKRT) as well. One severe COVID-19 patient received plasma exchange as well as CKRT. Serum creatinine values returned to normal in mean 3.07 days. CONCLUSIONS: Favipiravir seems a suitable therapeutic option in patients affected by COVID-19 with kidney injury without a need for dose adjustment.

RESUMO

BACKGROUND: Knowledge of infections leading to sepsis is needed to develop comprehensive infection prevention and sepsis, as well as early recognition and treatment strategies.The aim of this study was to investigate the etiology of sepsis and evaluate the proportion of respiratory viral pathogens in infants under two years of age with possible sepsis. METHODS: The prospective study was performed in two years. Multiplex reverse transcriptase polymerase chain reaction (RT-PCR) was performed to detect viral pathogens. All patients who were included in this study had sepsis symptoms as defined by the Surviving Sepsis Campaign. RESULTS: We compared 90 patients with sepsis into three groups as patients (n = 33) who had only viral positivity in nasopharyngeal swab, patients (17) had proven bacterial infection with or without viral infection, and patients (40) without the pathogen detection. Human rhinovirus (16.7%) and influenza (7.8%) were the most commonly seen viruses. A cough was more common in the viral infection group than other groups ( P = 0.02) and median thrombocyte count was lower in the bacterial infection group than the others ( P = 0.01). Patients having bacterial sepsis had the longest duration of hospitalization than the other groups ( P = 0.04). During winter and spring seaons, patients with sepsis had more viral infection; however, in summer and autumn period, patients were mostly in a state that we could not prove infection agents ( P = 0.02). CONCLUSIONS: Our results suggest that respiratory tract viruses may play an important role in patients with sepsis and they should be kept in mind, especially during winter and spring seasons. In overall infection, viral respiratory viruses as a single pathogen with a detection rate of 36.6% in sepsis etiology.

RESUMO

BACKGROUND: Catheter related blood stream infections (CRBSI) are mostly preventable hospital-acquired conditions. We aimed to investigate the value of presepsin in detection of CRBSI in hospitalized children. METHODS: Hospitalized pediatric patients who had clinical suspicion of CRBSI were followed. Results of peripheral blood cultures and blood cultures from central venous catheters, procalcitonin (PCT), C-reactive protein (CRP), total white blood cell (WBC) counts were recorded. Serum samples for presepsin were studied at the same time with the samples of healthy controls. The patients with positive blood cultures were defined as proven CRBSI and with negative cultures as suspected CRBSI. RESULTS: Fifty-eight patients and 80 healthy controls were included in the study. Proven CRBSI group consisted of 36 patients (62%) with positive blood cultures and compared with the suspected CRBSI group (n = 22, 36%) with negative culture results. There was no difference between proven and suspected CRBSI groups concerning WBC, PCT, CRP and presepsin. Presepsin was significantly higher in patient groups when compared with healthy controls. The receiver operating characteristic curve area under the curve was 0.98 (%95 CI: 0.97-1) and best cut-off value was 990 pg/ml. CONCLUSION: In hospitalized pediatric patients with CRBSI, presepsin may be a helpful rapid marker in early diagnosis.

RESUMO

Chronic necrotizing pulmonary aspergillosis (CNPA) is a condition caused by the ubiquitous fungus Aspergillus fumigatus in non-immunocompromised individuals. Numerous underlying conditions have been associated with CNPA. Tuberculosis, non-tuberculous mycobacterial infection and allergic bronchopulmonary aspergillosis (ABPA) remain the predominant risk factors for development of CNPA. Development of CNPA in echinococcal cyst cavities is very rare and the optimal therapeutic regimen and treatment duration have not been established. Here, we present a case of CNPA developed six years after the cystectomy operation of hydatid cyst and treated with voriconazole successfully.

Chryseobacterium indologenes is a widespread bacteria in the environment, especially hospitals, and a rarely reported human pathogen. The lowest frequency has been reported in children under 5 years of age. Clinical manifestations of C. indologenes include nosocomial pneumoniae, biliary tract infection, peritonitis, surgical wound infection, intravascular catheter-related bacteremia, cellulitis, and primary bacteremia. There is a knowledge gap in the management of C. indologenes infections, especially pertaining children, because of multiple antibiotic resistance and limited data in the literature concerning effective empirical treatment. In the published literature, a total of 16 cases of C. indologenes infections were reported in the pediatric age group. Herein, we present our experience in 6 children with C. indologenes infections. Early and prompt management of C. indologenes infections, particularly in children with mechanic ventilation, with polymicrobial infections, and under the age of 2 years, is of major importance because these factors seem to have a negative effect on the prognosis of infections caused by C. indologenes. Ciprofloxacin and TPM-SMX may be the best therapeutic choices for a combined initial empirical treatment of the patients.

RESUMO

Gastroesophageal disorders such as achalasia can be associated with pulmonary disorders because of non-tuberculous mycobacteria, frequently masquerading as aspiration pneumonia. The optimal therapeutic regimen and duration of treatment for non-tuberculous mycobacteria lung disease is not well established. Here, we present an 11 year old male patient with Mycobacterium abscessus pulmonary disease and underlying triple A syndrome, who was successfully treated with 2 months of imipenem, amikacin, clarithromycin and continued for long-term antibiotic treatment.

RESUMO

Nasal tuberculosis is a rare clinical entity which mainly presents in elderly people. Nasal tuberculosis has always been considered to be secondary to tuberculosis of the lungs, and in rare instances it is a primary infection, usually when mycobacteria are inhaled. We describe the case of a 10-year-old girl who was successfully treated for primary nasal tuberculosis. This patient is one of the very few children who have been reported to have primary nasal tuberculosis.

RESUMO

BACKGROUND: Previous studies in adults and case reports in children have shown increased frequency of hypothalamo-pituitary dysfunction after infectious diseases of the central nervous system. The aim of this study was to evaluate the function of hypothalamo-pituitary axis in children with a history of bacterial meningitis. METHODS: Patients diagnosed with bacterial meningitis between April 2000 and June 2011 was included. Baseline and stimulated hormonal tests were performed as required for hormonal evaluations following a diagnosis of meningitis. RESULTS: Pituitary function was assessed following a period of 8-135 months (mean 53 months) after bacterial meningitis. Thirty-seven cases (27 male, 15 pubertal) with mean age of 11.1 ± 4.4 years were included. Mean height SDS was 0.01 ± 1.07 and mean BMI SDS was 0.54 ± 1.15 all patients had a SDS above -2 SD. Baseline cortisol and low dose ACTH stimulation revealed normal adrenal functions in all patients. Gonadotropin deficiency was not detected in any of the pubertal cases. Four cases (10.8%) had low IGF1 and IGFBP3 z-scores (<-2 SD) according to age, sex and Tanner stage, but peak GH response in clonidin test was >10 ng/ml in three of them suggesting neurosecretary dysfunction of GH in these cases. The fourth case has died before the test. No one had TSH deficiency and diabetes insipidus, only one case had mild hyperprolactinemia. CONCLUSIONS: Our findings suggest that hypothalamo-pituitary dysfunction is not as common in childhood as in adulthood. The most remarkable finding was neurosecretary dysfunction of GH in some cases.

RESUMO

The aim of this study is to identify differences in distribution of Candida species, resistance to antifungals and clinical outcome, as well as the identification of potential risk factors associated with candidaemia in children. We conducted a retrospective analysis in children ≤18 years with blood culture proven candidaemia identified between 2004 and 2012. Patients were divided into two groups (Group 1, <3 months, n = 51; Group 2, ≥3 months, n = 197) to identify any potential difference between the neonatal and early infantile periods in terms of risk factors and distribution of Candida species. A total of 248 distinct episodes of candidaemia were identified over the study period. The most frequently isolated Candida species were C. albicans (53.2%), followed by C. parapsilosis (26.2%), C. tropicalis (8.1%). Of the 248 episodes, 71 episodes (28.6%) resulted in death within 30 days from the onset of candidaemia. In Group 1, failure of central venous catheter (CVC) removal was found to be associated with a 20.5-fold increase in mortality [95% CI (3.9, 106.5); P < 0.001], compared to a 5.9-fold increased risk with hypoalbuminaemia [95% CI (1.03, 34.1); P = 0.046]. For Group 2, the increased risk was 23-fold for failure of CVC removal [95% CI (7.48, 70.77); P < 0.001], 7.4-fold for mechanical ventilation [95% CI (2.64, 21.08); P < 0.001], 4.4-fold for hypoalbuminaemia [95% CI (1.56, 12.56); P = 0.005], 3.1-fold for neutropaenia [95% CI (1.31, 7.69); P = 0.010] and 2.2-fold for male gender [95% CI (1.02, 4.71); P = 0.043]. Therapeutic choices should be guided by sound knowledge of local epidemiological trends in candidaemia. Removal of CVC significantly reduces mortality and is an essential step in the management of candidaemia.
