RESUMEN
Background: Diabetic ketoacidosis (DKA) is the most serious metabolic complication of type 1 diabetes mellitus (T1DM). Insulin deficiency and inflammation play a role in the pathogenesis of DKA. The authors aimed to assess the systemic immune-inflammation index (SII) as a marker of severity among T1DM patients with DKA and without infection. Methods: The authors included T1DM patients older than or equal to 12 years hospitalized because of DKA. The authors excluded patients with infection or any condition that can change SII parameters or cause metabolic acidosis. The authors compared SII, neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR) between severe and non-severe DKA groups. The authors also assessed the need for an ICU, length of stay, and 90-day readmission rate between the groups. Results: The study included 241 patients with a median age of 17 (14, 24) years, and 44.8% were males. More patients with severe DKA (45%) required ICU admission (P<0.001). Median SII increased with DKA severity, and the difference was significant (P=0.033). No significant difference was observed as regards median NLR or PLR (P=0.380 and 0.852, respectively). SII, but not NLR or PLR, had a significant negative correlation with PH (r=-0.197, P=0.002) and HCO3 level (r=-0.144, P=0.026). Also, being in the highest SII quartile was an independent risk factor for DKA severity (OR, 2.522; 95% CI, 1.063-6.08; P=0.037). The authors estimated an SII cut-off value of 2524.24 to predict DKA severity with high specificity. Conclusion: Elevated SII is a risk factor for DKA severity in T1DM. It is better than NLR and PLR in prognosticating DKA patients. These findings highlight the role of inflammation in DKA. SII can help as a valuable and simple tool to assess DKA severity.
RESUMEN
INTRODUCTION: World Health Organization (WHO) is encouraging reporting of children with Multisystem Inflammatory Syndrome (MIS-C) associated with SARS-CoV-2 infection for better understanding and management of the disease. METHODOLOGY: This retrospective study included the first 15 pediatrics patient with a confirmed diagnosis of MIS-C associated with SARS-CoV-2 infection in the state of Qatar. We studied and analyzed their demographic data, clinical manifestations, laboratory tests, treatment, and outcome. RESULTS: A total of 15 children were studied (mean age 3.5 ± 2.7year). Recent severe acute respiratory syndrome coronavirus 2 infection was identified in all of them (100%). The majority of these patients had 4 or more systems involvement. Nine of the 15 presented with Kawasaki disease - picture and all had gastrointestinal symptoms (vomiting and diarrhea). Five required Pediatrics Intensive Care Unit (PICU) admission. Lab investigations revealed high D-Dimer, hyponatremia, and hypoalbuminemia in all. Low hemoglobin (Hb) , thrombocytopenia, and sterile pyuria occurred in 86.6%, 60% and 75% of them, respectively. Treatment with combined anti-inflammatory medications (intravenous immunoglobulin, corticosteroids) was used in along with immunomodulatory agents (Anakinra) in a selected group of refractory patients. No mortality happened. CONCLUSION: Our young children who presented with MIS-C related to SARS-CoV-2 infection had significantly higher Kawasaki-disease picture compared to other reports. One third of them required PICU admission but no mortality occurred.
