Objectives: The aim of this point prevalence survey was to evaluate the consumption, indications and strategies of antifungal therapy in the paediatric population in Turkey. Methods: A point prevalence study was performed at 25 hospitals. In addition to general data on paediatric units of the institutes, the generic name and indication of antifungal drugs, the presence of fungal isolation and susceptibility patterns, and the presence of galactomannan test and high-resolution computed tomography (HRCT) results were reviewed. Results: A total of 3338 hospitalised patients were evaluated. The number of antifungal drugs prescribed was 314 in 301 patients (9.0%). Antifungal drugs were mostly prescribed in paediatric haematology and oncology (PHO) units (35.2%), followed by neonatal ICUs (NICUs) (19.6%), paediatric services (18.3%), paediatric ICUs (PICUs) (14.6%) and haematopoietic stem cell transplantation (HSCT) units (7.3%). Antifungals were used for prophylaxis in 147 patients (48.8%) and for treatment in 154 patients (50.0%). The antifungal treatment strategy in 154 patients was empirical in 77 (50.0%), diagnostic-driven in 29 (18.8%) and targeted in 48 (31.2%). At the point of decision-making for diagnostic-driven antifungal therapy in 29 patients, HRCT had not been performed in 1 patient (3.4%) and galactomannan test results were not available in 12 patients (41.4%). Thirteen patients (8.4%) were receiving eight different antifungal combination therapies. Conclusion: The majority of antifungal drugs for treatment and prophylaxis were prescribed in PHO and HSCT units (42.5%), followed by ICUs. Thus, antifungal stewardship programmes should mainly focus on these patients within the availability of diagnostic tests of each hospital.

(2022) Avci, Begum; Baskin, Esra; Gulleroglu, Kaan; Ecevit, Zafer; Soy, Ebru Ayvazoglu; Moray, Gokhan; Haberal, Mehmet; 35570612
Objectives: BK polyomavirus infection is a critical complication affecting graft survival after kidney transplant. We aimed to determine the frequency, the effect on graft function, and the risk factors of BK polyomavirus infection in pediatric kidney transplant patients. Materials and Methods: We retrospectively reviewed data of 144 pediatric patients (female/male: 67/77; 0-18 years of age) who received kidney transplants in the past 10 years at our center. Demographic/laboratory data, kidney failure etiologies, donor types, and immunosuppressive treatments were recorded. Patients were grouped as those with and without BKV infection, with groups compared in terms of transplant age, sex, kidney failure etiology, donor type, immunosuppressive treatments, presence of ureteral stents, acute rejection episodes, accompanying viral infections, glomerular filtration rate, and graft loss rate. Results: Twelve patients (8.3%) had BK polyomavirus infection. All 12 patients had viruria (8.3%), 8 (5.5%) had viremia, and 4 (2.8%) had BK polyomavirus nephropathy. Two patients (1.4%) had graft loss because of BK polyomavirus nephropathy. When patients with and without infection were compared, no significant differences were found in terms of sex, transplant age, donor type, presence of a ureteral stent, acute rejection, graft loss, or immunosuppressive treatment (P > .05). Rates of congenital anomalies of the kidney and urinary tract were 30.3% and 66.6% in those without and with BK polyomavirus infection, respectively (P < .05). The group positive for BK polyomavirus had a significantly higher incidence of cytomegalovirus infection versus the group without infection (P < .05). Glomerular filtration rate values at years 1 and 3 were similar between groups (P > .05). Conclusions: Frequency of BK polyomavirus nephropathy in pediatric patients undergoing kidney transplant in our center was consistent with data from other centers. Graft loss can be prevented by early detection and treatment through close periodic control and adequate evaluation of risk factors.
Infective Endocarditis in Childhood: a Single-Center Experience of 18 Years
(2021) Yakut, Kahraman; Ecevit, Zafer; Tokel, Niyazi Kursad; Varan, Birgul; Ozkan, Murat; 0000-0002-6759-1795; 0000-0002-6719-8563; 33113327; AAF-3253-2021; ABB-1767-2021
Introduction: We aimed to present the risk factors, clinical and laboratory findings, treatment management, and risk factors for morbidity and mortality of infective endocarditis (IE) as well as to relate experiences at our center. Method: We retrospectively analyzed data of 47 episodes in 45 patients diagnosed with definite/possible IE according to the modified Duke criteria between May 2000 and March 2018. Results: The mean age of all patients at the time of diagnosis was 7.6 +/- 4.7 years (range: 2.4 months to 16 years). The most common symptoms and findings were fever (89.3%), leukocytosis (80.8%), splenomegaly (70.2%), and a new heart murmur or changing of pre-existing murmur (68%). Streptococcus viridans (19.1%), Staphylococcus aureus (14.8%), and coagulase-negative Staphylococci (10.6%) were the most commonly isolated agents. IE-related complications developed in 27.6% of the patients and the mortality rate was 14.8%. Conclusion: We found that congenital heart disease remains a significant risk factor for IE. The highest risk groups included operated patients who had conduits in the pulmonary position and unoperated patients with a large ventricular septal defect. Surgical intervention was required in most of the patients. Mortality rate was high, especially in patients infected with S. aureus, although the time between the onset of the first symptom and diagnosis was short. Patients with fever and a high risk of IE should be carefully examined for IE, and evaluation in favor of IE until proven otherwise will be more accurate. In high-risk patients with prolonged fever, IE should be considered in the differential diagnosis.
The Influence of Igm-Enriched Immunoglobulin Therapy on Neonatal Mortality and Hematological Variables in Newborn Infants with Blood Culture-Proven Sepsis
(2014) Abbasoglu, Aslihan; Ecevit, Ayse; Tugcu, Ali Ulas; Yapakci, Ece; Tekindal, Mustafa Agah; Tarcan, Aylin; Ecevit, Zafer; https://orcid.org/0000-0002-4060-7048; 25341598; ABI-2113-2020; U-9270-2018
The aim of this study was to determine the effects of adjuvant immunoglobulin M (IgM)-enriched intravenous immunoglobulin (IVIG) therapy on mortality rate, hematological variables and length of hospital stay in newborn infants with blood culture-proven sepsis. Demographic and clinical features and outcome measures of 63 newborn infants with blood culture-proven sepsis were documented retrospectively from the medical records. The patients were divided into two groups according to their treatment history. The patients in Group 1 received antibiotic therapy only and the patients in Group 2 received both antibiotic and adjuvant IgM-enriched IVIG. The study revealed that mortality rates were 28.1% and 12.9% in Group 1 and Group 2, respectively. The mortality rate was lower in Group 2, but the difference between the two groups was not statistically significant (p=0.21). Coagulase-negative Staphylococcus was the most common type of bacteria isolated from the blood culture in both groups. When changing laboratory results were compared between the two groups, hemoglobin, leukocyte count and C-reactive protein levels were different during the first three days of antibiotic treatment. Our study revealed that if diagnosed at an early stage and treated aggressively with appropriate and effective antibiotics, adjuvant IgM-enriched IVIG treatment has no additional benefits in neonatal sepsis.
