Abstract. Improving the availability of point-of-care (POC) diagnostics for glucose is crucial in resource-constrained settings (RCS). Both hypo and hyperglycemia have an appreciable frequency in the tropics and have been associated with increased risk of deaths in pediatrics units. However, causes of dysglycemia, including hyperglycemia, are numerous and insufficiently documented in RCS. Effective glycemic control with glucose infusion and/or intensive insulin therapy can improve clinical outcomes in western settings. A non-invasive way for insulin administration is not yet available for hyperglycemia. We documented a few causes and developed simple POC treatment of hypoglycemia in RCS. We showed the efficacy of sublingual sugar in two clinical trials. Dextrose gel has been recently tested for neonate mortality. This represents an interesting alternative that should be compared with sublingual sugar in RCS. New studies had to be done to document dysglycemia mechanism, frequency and morbid-mortality, and safe POC treatment in the tropics.Recently, Michael Hawkes and colleagues 1 reported the performance of point-of-care (POC) tests to guide the management of 179 children with severe malaria in a resource-limited Ugandan hospital. They paired measurements of glucose using i-STAT and OneTouch Ultra glucometer and other measurements for lactate and hemoglobin. Despite the small sample size of children with hypoglycemia and the lack of gold standard methods, they concluded that diagnostic tools, although imperfect, may expedite clinical decision-making in the management of critically ill children in resource-constrained settings (RCS). We completely agree with the crucial need for improving the availability of point-of-care diagnostics for glucose, particularly in RCS where hypoglycemia is a common and underdiagnosed cause of death.2-4 However, the sole diagnosis of dysglycemia is not sufficient if an access to effective therapy is not feasible, especially in the field for comatose children.For this purpose, we assessed the frequency of dysglycemia in sick children in non-malaria areas.2 In the pediatric ward of a referral hospital in Madagascar, an appreciable frequency (10.9%) (95% confidence interval [CI], 8.1-14.3) of hyperglycemic children at admission carried an increased risk of death (risk ratio [RR]: 2.2, 95% CI: 1-4.7).2 This association of hyperglycemia and increased mortality was described in rural Kenya and in a tertiary care hospital in India. 5,6 However, data on hyperglycemia frequency, causes, and mortality remains scarce in the tropics. 7,8 In the same study, we also found a 3.0% (95% CI, 1.6-5.2) prevalence of hypoglycemia among 420 consecutive children.2 Hypoglycemia was associated with increased risk of deaths (RR: 19.4, 95% CI: 5.0-74.7) after multivariate analyses. The rate of hypoglycemia was consistent with reports from Tanzania 9 but lower than rates reported in malaria areas.
