RESUMO
Resumen Desde finales del año 2019 un nuevo coronavirus, SARS-CoV-2, se extendió desde China hacia el resto del mundo, causando la pandemia de una enfermedad denominada COVID-19. Una enfermedad sistémica que en algunos casos produce neumonía severa que incluso puede progresar a falla respiratoria aguda y finalmente la muerte. Entre las comorbilidades que se han asociado con un aumento en la mortalidad por SARS-CoV-2 se encuentra la diabetes. En general, se estima que tener diabetes aumenta un 18 % el riesgo de infecciones respiratorias, en parte por el impacto que genera sobre la inmunidad innata o adquirida, lo que estaría contribuyendo a una presentación clínica más severa del SARS-CoV-2 al comparar con población sin diabetes. Considerando que existe una asociación entre mal control glucémico y mayor severidad clínica de la infección por COVID-19, se deben hacer importantes consideraciones sobre el manejo farmacológico brindado a los pacientes; el perfilamiento dependerá de las condiciones de cada paciente, de la severidad de la enfermedad y del tipo de manejo instaurado ya sea ambulatorio o intrahospitalario.
Abstract Since the end of the year 2019 a new coronavirus called Severe Acute Respiratory Syndrome (SARS-CoV-2) has spread from China to the rest of the world, causing the pandemic of the disease called COVID-19. A systemic disease that in some cases produces severe pneumonia that can even progress to acute respiratory failure and eventually death. Among the comorbidities that have been associated with an increase in mortality from SARS-CoV-2, diabetes is one of them. In general, it is estimated that having diabetes increases the risk of respiratory infections by 18 %, in part, due to the impact on innate and acquired immunity, which would be contributing to a more severe clinical presentation of SARS-CoV-2 when compared with population without diabetes. Considering that there is an association between worse glycemic control and higher clinical severity of COVID-19 infection, important considerations must be made regarding the type of pharmacological management that is provided to patients; the profiling will depend on the conditions of each patient, the severity of the disease, and the type of management either as outpatient or in-hospital.
RESUMO
BACKGROUND: Hyperglycemia is a frequent phenomenon in hospitalized patients that is associated with negative outcomes. It is common in liver transplant patients as a result of stress and is related to immunosuppressant drugs. Although studies are few, a history of diabetes and the presentation of hyperglycemia during liver transplantation have been associated with a higher risk for rejection. AIMS: To analyze whether hyperglycemia during the first 48hours after liver transplantation was associated with a higher risk for infection, rejection, or longer hospital stay. METHODS: A retrospective cohort study was conducted on patients above the age of 15years that received a liver transplant. Hyperglycemia was defined as a value above 140mg/dl and it was measured in three different manners (as an isolated value, as a mean value, and as a weighted value over time). The relation of hyperglycemia to a risk for acute rejection, infection, or longer hospital stay was evaluated. RESULTS: Some form of hyperglycemia was present in 94% of the patients during the first 48 post-transplantation hours, regardless of its definition. There was no increased risk for rejection (OR: 1.49; 95%CI: 0.55-4.05), infection (OR: 0.62; 95%CI: 0.16-2.25), or longer hospital stay between the patients that presented with hyperglycemia and those that did not. CONCLUSIONS: Hyperglycemia during the first 48hours after transplantation appeared to be an expected phenomenon in the majority of patients and was not associated with a greater risk for rejection or infection and it had no impact on the duration of hospital stay.
