We studied with great interest the article titled “Acute diarrhea and severe dehydration in children: Does non-anion gap component of severe metabolic acidemia need more attention?” by Takia L et al. and would express our views about the same. Normal anion gap metabolic acidosis (NAGMA) is a common entity following stool loss of bicarbonate during an acute diarrheal illness. Several studies have shown that there is a higher incidence of hyperchloremic acidosis and acute kidney injury (AKI) with normal saline (NS) when compared to balanced crystalloids like Ringer's lactate (RL) or balanced salt solutions like plasmalyte. We would like to know about the type of resuscitation fluid used in the study population as it would affect the degree of resolution of acidemia. As per the World Health Organization (WHO) guidelines, rehydration therapy for children with severe acute malnutrition (SAM) is different from other children including the fluid used for bolus, i.e., RL and oral rehydration solution (ORS), i.e., rehydration solution for malnourished (ReSoMal). We would like to know if the study population included SAM children and a subgroup analysis of the same was done as SAM is an independent risk factor for mortality and morbidity. We suggest to plan studies on cognitive outcome of these children.
