Abstract

Background Sepsis may lead to acute kidney injury (AKI)in patients treated in pediatric intensive care units (PICU).Currently, serum creatinine is used as a biomarker for thediagnosis of AKI. However, it is not a sensitive nor specifictest for AKI. The scarcity of biomarkers leads to delays in thediagnosis and treatment of AKI. Serum cystatin-C (sCys-C)and urinary neutrophil gelatinase-associated lipocalin (uNGAL)are potential biomarkers that look promising for early diagnosisof AKI.Objective To identify the relation of cystatin-C and NGAL inchildren with sepsis.Methods Serum cystatin-C and uNGAL were measured onseptic patients aged one month to 12 years. The diagnosesof sepsis were based on the 2002 International Pediatric SepsisConcensus. Patients were admitted to the Pediatric IntensiveDepartment of the Prof. Dr. R. D. Kandou Hospital, Manadofrom January to June 2013. The exclusion criteria werepatients with trauma, burns, severe dehydration, malnutrition,obesity, and history of renal diseases. Data analyses includeddescriptions for the characteristic data and Pearson’s coefficientcorrelation. A P value of 0.05 was considered to be statisticallysignificant. Data were analyzed with SPSS software for Windowsversion 21.Results Thirty-eight patients met the inclusion criteria, of whom23 were male and 15 were female. Their mean age was 22.6 (SD32.24) months, with overweight in 2 children, good nutrition in25 children, and under nutrition in 11 children. An increasedlevel of sCys-C was found in 22 children and an increased levelof uNGAL was found in 19 children. Serum cystatin-C wassignificantly correlated to uNGAL in septic patients (r=0.614;P<0.01).Conclusion There is a positively correlated relationship betweensCys C and uNGAL in septic children. Increased sCys C is associated with increased uNGAL in septic children.

Abstract

Background Acute diarrhea is currently one of the major causes of morbidity and mortality in developing countries. A wide range of enteric pathogens, including bacteria, is responsible for the pathogenesis of acute infectious diarrhea. Recent studies have shown an increase in acute phase proteins, such as serum interleukin-6 (IL-6) levels, in patients with acute bacterial gastroenteritis. Thus, IL-6 may be a useful marker to differentiate bacterial from non-bacterial enteric pathogens.Objective To assess for a correlation between bacterial enteric pathogens and serum IL-6 levels in children with acute diarrhea.Methods We conducted a cross-sectional study from November 2013 to March 2014 in two hospitals in Manado. Subjects were children aged 1-5 years with acute diarrhea and good nutritional status. Subjects’ provided stool samples for bacterial culture and microscopic examination, as well as blood specimens for serum IL-6 measurements. Data was analyzed by linear regression and Pearson’s correlation tests for a correlation between bacterial enteric pathogens and serum IL-6 levels.Results In children with acute diarrhea, those with bacterial enteric pathogens had significantly higher mean serum IL-6 than those with non-bacterial enteric pathogens (r = 0.938; P < 0.001).Conclusion Serum IL-6 levels are significantly more elevated in children with acute diarrhea and bacterial enteric pathogens. Therefore, serum IL-6 may be a useful marker for early identification of bacterial gastroenteritis in children aged 1-5 years. [Paediatr Indones. 2016;56:144-8.].

Abstract

Background Acanthosis nigricans (AN) is a skin condition characterized by darkening and thickening of skin. AN has been reported to be linked to insulin resistance (IR), that associated with type 2 diabetes, in obese children in many country.Objective To determine the relation between acanthosis nigricans and insulin resistance in obese children.Methods We conducted a cross sectional study in Wenang District, Manado, from October 2009 until January 2010. We examined 54 obese children aged 10-14  years for insulin resistance using Homeostasis Model Assessment of Insulin Resistance Index (HOMA-IR). We analyzed the results byT-test and phi coefficient correlation. The value of P<O.05 was significant in statistical analysis.Results Acanthosis nigricans was positive in 33 children. Insulin resistance was found in 34 from 54 subjects, 28 of them has AN and 6has no AN. Obese children with AN had higher HOMA-IR than children without AN. Presence of AN was associated with IR (P<O.OOl, r=0.57).Conclusions There is a weak correlation between AN and IR in obese children. It is important to identify obese children with IR for early intervention and prevention of type  2 diabetes, but AN could not be a reliable marker of IR.
