Immune thrombocytopenia (ITP) is a potential presentation of COVID-19. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral testing should be considered in these patients to allow for appropriate hospital triaging and isolation to limit community spread and health care worker infection during epidemics or pandemics. ITP is characterized by isolated thrombocytopenia. Approximately two-thirds of children with primary ITP have a history of a viral infection during the previous month.1,2 Viruses commonly identified as triggers include cytomegalovirus, hepatitis C, herpes, varicella zoster, Epstein-Barr, influenza, and HIV.3–7 In this case report, we describe the first documented case of a pediatric patient with ITP who tested positive for SARS-CoV-2. This case raises awareness of ITP as a possible pediatric presentation of coronavirus disease.
End-tidal CO(2) is linearly related to HCO(3) and is significantly lower in children with DKA. If confirmed by larger trials, cut-points of 29 torr and 36 torr, in conjunction with clinical assessment, may help discriminate between patients with and without DKA, respectively.
Background: Patients with diabetic ketoacidosis (DKA) hyperventilate, lowering their alveolar (PACO 2 ) and arterial carbon dioxide (PaCO 2 ). This ventilatory response lessens the severity of their acidemia in a predictable way. Because end-tidal CO 2 (ETCO 2 ) closely approximates PaCO 2 , measured ETCO 2 levels should allow for predictions about the presence and severity of acidosis in diabetic patients. Objectives: 1) To evaluate the relationship between measured serum bicarbonate (HCO 3 ) and ETCO 2 measured via nasal capnography in children with suspected DKA; and 2) to assess the ability of capnography to predict DKA. Methods: Children being evaluated in a pediatric emergency department for suspected DKA (known or suspected diabetes presenting with hyperglycemia with or without ketonuria) were enrolled in a cross-sectional, prospective, observational study. Prior to the availability of venous HCO 3 results, ETCO 2 values were measured using a Nellcor NPB-70 Handheld Capnograph. Results: Forty-two patients were
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
