ABSTRACT
BACKGROUND: Survivors of childhood cancer are at increased risk for several cardiometabolic complications. Obesity/overweight and metabolic syndrome have been widely reported in Western literature, but data from India are lacking. AIMS: To perform an objective assessment of nutritional status in a cohort of childhood cancer survivors (CCSs) and to find risk factors for extremes in nutritional status. SETTINGS AND DESIGN: The study was a retrospective chart review of CCSs who attended the late effects clinic of a referral pediatric oncology center over the period of 1 year. MATERIALS AND METHODS: An objective assessment of nutritional status was done, and results were analyzed in two groups: Adult survivors (present age >18 years) and child and adolescent survivors (CASs) (<18 years). The data were then analyzed for possible risk factors. RESULTS: Six hundred and forty‑eight survivors were included in the study; of these, 471 were <18 years at follow‑up, and 177 were 18 years or older. The prevalence of obesity, overweight, normal, and undernutrition was 2.6%, 10.8%, 62.7%, and 28.8% (CASs) and 0%, 8.5%, 62.7%, and 28.8% (adult survivors), respectively. Factors predictive of overweight/obesity were an initial diagnosis of acute lymphoblastic leukemia, or brain tumor and follow‑up duration of >20 years or current age >30 years in adult survivors. CONCLUSIONS: The prevalence of obesity/overweight is lower in our cohort when compared to Western literature. It remains to be clarified whether this reflects the underlying undernutrition in our country, or whether our cohort of survivors is indeed distinct from their Western counterparts. Comparison with age/sex‑matched normal controls and baseline parameters would yield more meaningful results.
ABSTRACT
BACKGROUND: Infection or colonization with multidrug‑resistant organisms (MDRO) is associated with high mortality and morbidity. Knowledge of MDRO colonization may help in planning empirical antibiotic approach in neutropenic patients, which is known to improve patient outcomes. While routine cultures are positive and may help direct antibiotic therapy in only up to 15% neutropenic patients, surveillance cultures are positive in more than 90% of cancer patients. AIMS: To assess the rate of MDRO carrier status at presentation and rate of conversion to MDRO during the treatment. MATERIALS AND METHODS: Rectal swabs of all the outpatients presenting to pediatric oncology unit were sent within 7 days from date of registration from January 2014 to December 2014. Furthermore, stool cultures/rectal swabs of all patients who got directly admitted to the pediatric ward at presentation were sent within 24 h. Repeat rectal swabs were sent again for patients from this cohort when they got readmitted to the ward at least 15 days after last discharge or when clinically indicated. RESULTS: Baseline surveillance rectal swabs were sent for 618 patients, which included 528 children with hematological malignancies and 90 children with solid tumors. Forty‑five (7.3%) showed no growth. Of the remaining 573, 197 (34.4%) patients were colonized by two organisms and 30 (5.2%) by three organisms. Three hundred and thirty‑four (58.4%) showed extended spectrum beta‑lactamase (ESBL) Enterobacteriaceae, of which 165 (49.5%) were ESBL sensitive to beta‑lactam with beta‑lactamase inhibitors combinations and 169 (50.5%) were resistant to combinations. One hundred and sixteen (20.2%) were carbapenem‑resistant Enterobacteriaceae (CRE) and 65 (11.4%) had vancomycin‑resistant enterococci in baseline cultures. Only 63 (21%) patients were colonized by a sensitive organism in their baseline surveillance cultures. Morbidity (Intensive Care Unit stay) and mortality was higher in patients colonized by MDR organisms. There was a significant correlation between the place of residence and CRE colonization status with the highest rate (60%) of CRE colonization observed in children from East India. The repeat cultures showed the further conversion of sensitive isolates to MDRO in 80% of these children, of which 40% each converted from non‑ESBL and non‑CRE to ESBL and CRE, respectively. CONCLUSION: This is the first study illustrating the alarming high prevalence of community‑acquired MDRO colonization, especially CRE, which has grave implications for therapy for children with cancer potentially compromising delivery of aggressive chemotherapy and affecting outcomes. This incidence further increases during the course of treatment. Knowing the baseline colonization also guides us for the planning of chemotherapy as well as antibiotic approach and infection control strategies. Local antibiotics stewardship including education of the healthcare workers as well as national level interventions to prevent antibiotic misuse in the community is critical to minimize this problem.
ABSTRACT
BACKGROUND: Blood stream infections (BSI) are among the most common causes of preventable deaths in children with cancer in a developing country. Knowledge of its etiology as well as antibiotic sensitivity is essential not only for planning antimicrobial policy, but also the larger infection prevention and control measures. AIMS: To describe the etiology and sensitivity of BSI in the pediatric oncology unit at a tertiary cancer center. MATERIALS AND METHODS: All the samples representative of BSI sent from pediatric oncology unit during the period of January to December, 2013 were included in the study, and analyzed for microbiological spectrum with their antibiotic sensitivity. RESULTS: A total of 4198 samples were representative of BSI. The overall cultures positivity rate was 6.97% with higher positivity rate (10.28%) from central lines. Of the positive cultures, 208 (70.9%) were Gram‑negative bacilli (GNB), 71 (24.2%) were Gram‑positive organisms, and 14 (4.7%) were Candida species. Lactose fermenting Enterobacteriaceae i.e., Escherichia coli (28.4%), Klebsiella pneumoniae (22.1%), and Enterobacter (4.8%) accounted for 55.3% of all GNB. Pseudomonas accounted for 53 (25.5%) and Acinetobacter 19 (9.1%) of GNB. Among Gram‑positive isolates, staphylococci were the most frequent (47.8%), followed by Streptococcus pneumoniae 17 (23.9%), beta‑hemolytic streptococci 11 (15.5%), and enterococci 9 (12.68%). Of GNB, 45.7% were pan‑sensitive, 24% extended spectrum beta–lactamase (ESBL) producers, 27% were resistant to carbapenems, and 3.4% resistant to colistin. Pseudomonas was most sensitive, and Klebsiella was least sensitive of GNB. Of the staphylococcal isolates, 41.67% were methicillin-resistant Staphylococcus aureus (MRSA) and 10% of Coagulase Negative Stapylococci (CONS) were methicillin. CONCLUSION: A high degree of ESBL producers and carbapenem‑resistant Enterobacteriaceae is concerning; with emerging resistance to colistin, raising the fear of a return to the preantibiotic era. An urgent intervention including creating awareness and establishment of robust infection control and antibiotic stewardship program is the most important need of the hour.
ABSTRACT
BACKGROUND: Risk stratification of patients with febrile neutropenia (FN) into those at “High Risk” and “Low Risk” of developing complications helps in making decisions regarding optimal treatment, such as whether to treat with oral or intravenous antibiotics, whether to treat as inpatient or outpatient and how long to treat. Risk predictors obtained from Western studies on pediatric FN are unlikely to be relevant to low middle‑income country (LMICs). Our study aimed to identify clinical and laboratory parameters predictive of poor outcomes in children with chemotherapy‑induced FN in a LMIC. PROCEDURE: Two hundred and fifty consecutive episodes of chemotherapy‑induced FN in pediatric (<15 years) patients were analyzed prospectively. Adverse outcomes were defined as per SPOG 2003 FN study as serious medical complications (SMC) due to infection, microbiologically defined infection, and radiologically defined pneumonia (RDP). Variables found to be significant for adverse outcome (P < 0.05) on univariate analysis were selected for multivariate analysis. RESULTS: Five factors that were found to independently predict adverse outcome were (a) previously documented infection in the past 6 months, (b) presence of significant focus of infection, (c) absolute phagocyte count <100/mm3, (d) peak temperature more than 39°C in this episode of FN, and (e) fever lasting more than 5 days during this episode of FN. CONCLUSIONS: Identifying the risk factors for adverse outcome in pediatric FN, which are objective and applicable across LMICs would contribute in developing guidelines for the management of FN in a resource‑limited setting.
