Abstract

Objective: To describe the pattern of random blood glucose levels of children presenting at the children outpatient department of the Ekiti State University Teaching Hospital (EKSUTH), Ado-Ekiti

Method: Consecutive children aged 15years and below who presented at the Children Out-Patient Department (COPD) of EKSUTH between January 2015 and May 2015 whose parent or guardian gave consent to participate in the study had their random blood glucose done and the result analyzed with statistical package for social science (SPSS).

Results: 605 children (366 males and 239 females) were studied, 70.4% of them were aged < 5years at the time of the study. Random blood glucose of the studied children ranged from 1.2 to 25.0mmol/L. The mean RBG was 6.42 ± 0.75. Majority (86.8%) of the patients were euglycaemic, 12.9% were hyperglycemic while 0.3% were hypoglycemic. Of the 525 patients who were euglycemic 93(17.7%) were admitted compared to 38(48.7%) of the 78 patients with hyperglycemia; the difference was statistically significant (z2 = 51.083; p= 0.000). 95(15.7%) of the 605 patients drank fizzy drinks within 2hours before RBG check and none (0%) of these had hypoglycemia; 76(80%) were euglycaemic; 14(14.7%) were hyperglycemic and 5(5.3%) had profound hyperglycemia compared to 2(0.4%), 449(88.0%), 52(10.2%) and 7(1.4%) who had hypoglycemia, euglycaemia, hyperglycemia and profound hyperglycemia respectively of the remaining 510(84.3%) patients who did not drink any fizzy drink. The difference was statistically significant (x2=8.594; p=0.035)

Conclusion: Transient hyperglycemia is relatively common among acutely ill children seen in Children Out-Patient Department, though majority of them are able to maintain normal blood glucose with or without fizzy drinks.

Introduction

Disorders of glucose metabolism often accompanies acute illnesses [1,2]. It has also been postulated that hyperglycemia during acute illness may put affected patients at a higher risk of developing type 2 diabetes mellitus later in life [3,4]. Hyperglycemia during acute illness may be caused by mediators of stress and inflammation [3]. Hyperglycemia is commoner in severely ill patients but not all critically ill patients develop Hyperglycemia. Hyperglycemia can also occur in patients with mild illness who did not previously have history of diabetes [1-4]. Hypoglycemia has also been documented in ill Pediatric patients [2]. Hypoglycemia may result from reduced oral intake during illness, rapid utilization of glucose by plasmodium falciparum in severe malaria and drug- induced hyperinsulinism where quinine is used for treatment of severe malaria [2,5,6]. Failure to identify the disorder of glucose metabolism associated with acute illnesses can have short and long term adverse effect on patients [2-4]. Studies on the pattern of random blood glucose among ill children in Pediatric Out-Patient are very scarce; most published studies within and outside Africa [1-12] were conducted on critically ill patients in emergency wards or intensive care units hence the need for this study to validate the disorder of glucose metabolism among ill children seen in Pediatrics Out-Patient Department with a view to proffering practical recommendations for early detection and management of disorders of glucose metabolism associated with acute illnesses in children managed on out-patient basis.

Method

Consecutive non diabetic children aged 15years and below who presented at the Children Out-Patient Department (COPD) of EKSUTH between January 2015 and May 2015, whose parent or guardian gave consent to participate in the study had their random blood glucose done after entering their demographic and clinical data into a questionnaire and the result was analyzed with statistical package for social science (SPSS) version 22.

A total of 605 children aged 15years and below were enrolled for the study. Their mean age was 4.25 ± 0.17years. There were 366 males and 239 females giving male: female ratio of 1.5:1. Majority, 426(70.4%) of these children were in the age group five years and below (Table 1). The duration of illness before presentation ranged from few hours to 365 days. 95(15.7%) of the studied children have been given fizzy drink within 2hours before the random blood glucose (RBG) test. The RBG of the studied children ranged from 1.2 to 25.0mmol/L. The mean RBG was 6.42 ± 0.75. Majority (86.8%) of the patients were euglycaemic, 0.3% were hypoglycemic while 12.9% were hyperglycemic (Table 2). None of the 12(2%) patients who had profound Hyperglycemia in the diabetic range was confirmed to have diabetes; the result of their follow-up fasting blood glucose was within normal limit.

Of the 525 patients who were euglycemic 93(17.7%) were admitted compared to 38(48.7%) of the 78 patients with Hyperglycemia; the difference was statistically significant (x2 = 51.083; p= 0.000). Of the 605 studied children 443(73.2%) were treated and followed up on outpatient basis; 132(21.8%) were admitted into children emergency ward while 30(5%) were referred to other specialties like Surgery. The four commonest presentation at children outpatient department of EKSUTH were respiratory tract infection (23.5%), malaria (22%), gastroenteritis (12.4%) and skin rashes (9.4%) as shown in Table 3.

Comparing the blood glucose value of those who had fizzy drinks and those who did not within 2hours of presentation: of the 95 patients who drank fizzy drinks within 2hours before RBG check, none (0%) had hypoglycemia; 76(80%) were euglycaemic; 14(14.7%) were hyperglycemic and 5(5.3%) had profound Hyperglycemia compared to 2(0.4%), 449(88.0%), 52(10.2%) and 7(1.4%) who had hypoglycemia, euglycaemia, Hyperglycemia and profound Hyperglycemia respectively of the 510 patients who did not drink any fizzy drink within 2hours before RBG check (Table 4). The difference was statistically significant (x2=8.594; p=0.035).

Table 4: Cross tabulation of RBG of children who ingested fizzy drink against those who did not (x2=8.594; p=0.035).

Of the 442 patients who presented within 7days of their illnesses, 2(0.5%) had hypoglycemia, 369(83.5%) were euglycaemic, 59(13.3%) had Hyperglycemia and 12(2.7%) had profound Hyperglycemia compared to 0(0%), 156(95.7%), 7(4.3%) and 0(0%) who had hypoglycemia, euglycaemia, Hyperglycemia and profound Hyperglycemia respectively of the 163 patients who has been ill for more than 7days before presentation (Table 5). The difference is statistically significant (x2=16.161; p=0.001).

Logistic regression was done using independent variables like sex, age, RBG, duration of illness, and ingestion of fizzy drink against outcome (whether or not patient was admitted). Only duration of illness and RBG level was found to be predictive of whether or not patient will be admitted into children emergency ward from the children outpatient department (p= 0.001 and 0.000; β coefficient 0.399 and 0.277 respectively). The other factors (age and sex,) were not predictive of outcome; they had p value > 0.05 (Table 6).

Discussion

Disorder of glucose metabolism is well documented in studies among acutely ill children and adults admitted into emergency or intensive care units within and outside Africa [1-12]. There are no known published studies of disorder of glucose disorder among ill children seen in Children Out-Patient Department (COPD). The index study therefore sought to document pattern of random blood glucose among children seen in the COPD of Ekiti State University Teaching Hospital (EKSUTH), Nigeria. A total of 605 children were seen during the 5months study period and duration of illness ranged from few hours to 365days. 443(73.2%) of the 605 studied children were treated and followed up on outpatient basis; 132(21.8%) were admitted into children emergency ward while 30(5%) were referred to other specialties like Surgery. The four commonest presentations at COPD of EKSUTH were respiratory tract infection (23.5%), malaria (22%), gastroenteritis (12.4%) and skin rashes (9.4%) as shown in Table 3. This is comparable to presentations at Komfo Anokye Teaching Hospital, Kumasi, Ghana [7] and in Lagos University Teaching Hospital, Nigeria [10] where severe malaria, diarrhea and vomiting, acute respiratory tract infections, and septicaemia were the 4 commonest presentations. Understandably, uncomplicated respiratory tract infection, malaria and diarrhea with vomiting were the commonest in the index study because it was done among children seen on out-patient basis compared to those seen among children admitted to emergency wards.

Hypoglycemia in the index study is very low 0.3% compared to 3.1%, 5.6%, 6.5% and 7.7% in studies among admitted critically ill children in Mdagaster [11], Nigeria(Lagos) [10], Ghana [7], and Mozambique [2]. The low incidence of hypoglycemia among children seen in out-patient department can be explained by the less severe nature of illnesses among children presenting in COPD compared to those admitted into children emergency ward. Also, children presenting in out-patient departments would have been offered one fizzy drink or the other, however little, helping to maintain their blood glucose and preventing hypoglycemia. The few ones who were hypoglycemic were too ill to accept any food or drink and were admitted into children emergency ward for management. None of the children given fizzy drinks within 2hours of RBG check had hypoglycemia compared to 0.4% of those not given fizzy drinks who developed hypoglycemia. This may lend credence to the importance of giving glucose containing fluids, including oral rehydration salt, to ill children who are refusing household diet until they are able to accept regular diet in order to prevent hypoglycemia.

The proportion of children with Hyperglycemia in the index study was 12.9%. This is low compared to 43.5% among admitted sick Ghanaian children [7] and 15.9% among Mozambique children [2]. The study among Mozambique children was conducted mainly on children with severe malaria. Consumption of glucose by P falciparum coupled with reduced oral intake by patients with severe malaria may have mitigated against the expected Hyperglycemia induced by stress of severe illnesses [2,5,13,14]. Hyperglycemia in the index study among children seen on out-patient basis can be partly explained by high glucose content of various fizzy drinks offered the ill children to pacify or to encourage them to take their medication. Also, stress induced gluconeogenesis will play a significant role though not as much as would be expected in critically ill children admitted into intensive care units. 20% of the children who were given fizzy drinks in the index study had transient Hyperglycemia compared to 11.3% of those who were not offered fizzy drink. All the children who had Hyperglycemia eventually had normal fasting blood glucose and none was diabetic. There is need for moderation in administration of fizzy drinks to pacify ill children as this can greatly distort their glucose metabolism and may put them at higher risk of developing diabetes later in life [3,4].

Normal blood glucose was recorded in 86.6% of children seen in COPD and this is higher than 50% and 74% normal RBG recorded among critically ill children admitted into emergency wards in Ghana and Mozambique respectively [7,2]. Children seen on outpatient basis were able to maintain normal blood glucose because of ability to take in food and drinks, however little, compared to the critically ill children who most often are not able to tolerate orally. The ability of majority of children to maintain normal blood glucose during mild illness should help to reassure parents and care-givers that their children will be able to cope very well if they present early for appropriate treatment on out-patient basis. Those who are having acute watery diarrhea should continue to administer oral rehydration salt until the diarrhea subsides.

Dysglycaemia was significantly more prominent in children with acute illnesses who presented within 7days of onset of their illnesses compared to those whose illnesses has been on for more than 7days before presentation. Our finding suggests that recognition of dysglycaemia in children presenting in COPD can be improved as this may help in giving prompt attention to those that need urgent medical assistance. It will also serve as screening for pre-diabetes and diabetes in children and adolescents. Previous study at EKSUTH [15] showed that 100% of children with type 1 diabetes presented in emergency (diabetic ketoacidosis) compared to some developed countries where less than 50% of their diabetic children presented in emergency [16,17].
