RESUMO
Aims: To evaluate the frequency of diabetes and admission hyperglycaemia in Mexican COVID-19 patients, to describe the clinical and biochemical characteristics of patients with admission hyperglycaemia and to determinate the impact of diabetes and admission hyperglycaemia on COVID-19 severity and mortality. Methods: A multicentric study was performed in 480 hospitalized patients with COVID-19. Clinical and biochemical characteristics were evaluated in patients with admission hyperglycaemia and compared with non-hyperglycaemic patients. The effect of diabetes and admission hyperglycaemia on severity and risk of death were evaluated. Results: Age was 50.7 ± 13.6 years; 68.3% were male. Some 48.5% (n = 233) had admission hyperglycaemia; 29% (n = 139) of these patients had pre-existing diabetes. Patients with admission hyperglycaemia had more requirement of invasive mechanical ventilation (IMV), higher levels of urea, D-dimer and neutrophil-lymphocyte ratio (NLR), as well as lower lymphocyte count. An association between admission hyperglycaemia with IMV and D-dimer with glucose was found. Age ≥50 years (OR 2.09; 95%CI 1.37-3.17), pre-existing diabetes (OR 2.38; 95%CI 1.59-5.04) and admission hyperglycaemia (OR 8.24; 95%CI 4.74-14.32) were risk factors for mortality. Conclusions: Admission hyperglycaemia is presented in 48.5% of COVID-19 patients. Diabetes and admission hyperglycaemia are associated with the severity of disease and mortality. This study shows the devastating conjunction of hyperglycaemia and COVID-19. Clinical trial registration: Clinical characteristics of patients with COVID-19, DI/20/204/04/41 (Hospital General de Mexico) and NR-13-2020 (Hospital Regional de Alta Especialidad Ixtapaluca).

Resumen OBJETIVO: Recopilar casos atendidos en centros oncológicos de México y reportar los tratamientos exitosos, con respuestas completas y las complicaciones del embarazo. MATERIALES Y MÉTODOS: Estudio retrospectivo de serie de casos que incluyó a pacientes con leucemia promielocítica aguda asociada con el embarazo atendidas en diferentes hospitales de la zona metropolitana de la Ciudad de México entre 1999 y 2021. RESULTADOS: Se identificaron 17 pacientes con leucemia promielocítica aguda asociada con el embarazo, con mediana de edad de 23 años (14-40 años); 7 correspondieron a madres menores de 20 años. En relación con su entorno social 9 tenían baja escolaridad, 12 se dedicaban al hogar y 13 tenían una pareja al momento de la concepción. Por último, 11 eran originarias de una zona urbana. Las pacientes atendidas entre 1999-2010 se trataron con interferón plus citarabina (7 de 17) o mediante soporte transfusional y esteroide (2 de 17), en 8 de los 17 casos el tratamiento se inició con tretinoína en combinación con quimioterapia (daunorrubicina) como tratamiento de inducción. CONCLUSIONES: El tratamiento de pacientes embarazadas y con leucemia promielocítica aguda representa un reto debido al riesgo trombótico y hemorrágico. Si bien la adición de tretinoína ha modificado el pronóstico de las pacientes con esta leucemia, su indicación a las embarazadas sigue siendo motivo de controversia, sobre todo por el riesgo de teratogenicidad.
Abstract OBJECTIVE: To collect cases attended in oncology centers in Mexico and to report successful treatments, with complete responses and complications around gestation. MATERIALS AND METHODS: Retrospective case series study including patients with pregnancy-associated acute promyelocytic leukemia attended in different hospitals in the metropolitan area of Mexico City between 1999 and 2021. RESULTS: Seventeen patients with pregnancy-associated acute promyelocytic leukemia were identified, with a median age of 23 years (14-40 years); 7 corresponded to mothers younger than 20 years. In relation to their social environment, 9 had low schooling, 12 were homebased and 13 had a partner at the time of conception. Finally, 11 were originally from an urban area. Patients seen between 1999-2010 were treated with interferon plus cytarabine (7 of 17) or by transfusion support and steroid (2 of 17), in 8 of the 17 cases treatment was initiated with tretinoin in combination with chemotherapy (daunorubicin) as induction therapy. CONCLUSIONS: Treatment of pregnant patients and patients with acute promyelocytic leukemia represents a challenge due to thrombotic and hemorrhagic risk. Although the addition of tretinoin has modified the prognosis of patients with this leukemia, its indication in pregnant women remains controversial, especially because of the risk of teratogenicity.
