Total serum cortisol level is low in children with severe dengue shock syndrome.

Dengue shock syndrome (DSS) is a potentially critical and life-threatening concern, especially in children of tropical countries. The serum cortisol levels in severe DSS or later stages of DSS are limited references. We prospectively studied an association between of serum cortisol as well as interleukin levels and the severity of DSS in pediatric patients. A prospective cross-sectional study of 35 consecutive DSS cases (3 months to 16 years old) admitted to our institution from July 1, 2019, to June 30, 2020 was conducted. Serum cortisol, IL-6, and IL-10 were measured at T0 (shock recognition) and T12 (12 hours after T0); their values were presented as median and interquartile ranges (25%-75%). Severe DSS included patients with impalpable pulses or systolic blood pressure < 70 mmHg, recurrent shock, and prolonged shock. In contrast, non-severe DSS presented circulatory failure without any features of severe DSS. A total of 8 (22.8%) severe DSS patients expressed the cortisol (T0) significantly lower compared to the non-severe DSS group (7.3 µg/dl versus 14.3 µg/dl, p=0.008). In severe DSS, there was a minimal change in cortisol levels between T0 and T12 (7.3 µg/dl and 4.7 µg/dl p>0.05), whereas the decrease is significant in their counterparts (14.3 µg/dl to 5.6 µg/dl, p<0.005). Additionally, there were moderate correlations between IL-6 (T0), IL-10 (T0), IL-10 (T12) and total fluid requirement (Spearman's rho = 0.47, 0.4, and 0.36, respectively; p<0.05). Our study demonstrated that adrenal dysfunction was present in patients with severe and non-severe DSS, as noted by cortisol level at T12. In addition, IL-6 and IL-10 levels are correlated with the total fluid requirement, which is a marker of DSS severity. Further studies could reveal how adrenal dysfunction in pediatric patients with DSS can affect outcomes and the potential roles of interleukin levels in fluid management strategy.
