[Clinical Characteristics and outcomes of adults with COVID-19 admitted to a Pediatric Intensive Care Unit]

OBJECTIVE

To describe a cohort of critically ill adult patients suffering from COVID-19, admitted to a pediatric intensive care unit managed by a pediatric intensive care team (ICU-MP).

PATIENTS AND METHOD

Retrospective observational study of adults admitted to the ICU-MP due to COVID-19 from May 11 to July 26, 2020. Demographic, clinical, biochemical, ventilatory support characteris tics, and complications were recorded. Disease severity was characterized by Acute Physiology and Chronic Health Evaluation II score (APACHE II) using data from the first 24 hours of admission to the ICU-MP.

RESULTS

Ninety-three patients over 18 years with suspected or confirmed COVID-19 were admitted to the ICU-MP. The median age was 60.3 years (SD 13.9), and 59 (63.4%) patients were male. Eighty-two (88.1%) patients had at least 1 medical comorbidity. The median APACHE II score was 9.4 points (SD 5.6). Fifty-one (54.8%) patients were invasively ventilated, for a median of 13.7 days (SD 17.9). Inotropic support was used in 45 (48%) patients. Thirty-three (35.5%) patients presented acute kidney injury (AKI) and 14 (15.1%) patients received continuous renal replacement therapy. Twenty-nine (31.2%) patients had healthcare-associated infections. The median ICU-MP stay was 10.8 days (SD 11.8). 25 (26.9%) patients died, ten of them (40%) had adequacy of thera peutic effort.

CONCLUSIONS

The mortality rate of critically ill patients with COVID-19 is high. Older patients (> 70 years), those who require invasive mechanical ventilation and who develop AKI are at increased risk of death. Although this is not a comparative study, our mortality rate and complica tions seem to be similar to those reported in adult case series.

[Deferasirox and Complex Proximal Tubulopathy. Presentation of two clinical cases]

INTRODUCTION

Treatment with iron chelators is essential for patients with iron overload secondary to repeated trans fusions. Deferasirox is the first once-daily oral active iron chelator. As a result, therapeutic adherence has improved, reducing the complications of iron overload, especially heart failure. However, it is not exempt from possible side effects, such as kidney involvement, which is more frequent in children.

OBJECTIVE

To report 2 patients with Diamond-Blackfan anemia (DBA) who developed impaired renal function secondary to the administration of Deferasirox.

CLINICAL CASES

Case 1. A 15-year-old adolescent diagnosed with DBA undergoing treatment with periodic transfusions and Deferasirox. During an acute gastroenteritis, she developed acute renal failure along with complex proximal tubu- lopathy. Case 2. A 5-year-old boy diagnosed with DBA receiving periodic transfusions and treatment with Deferasirox. He presented polyuria with laboratory abnormalities compatible with acute renal failure and proximal tubular dysfunction. In both cases, they were adequately hydrated and Deferasi rox was temporarily suspended, improving renal function.

CONCLUSION

Based on these cases, close monitoring of renal and tubular function, as well as ferritin levels, is recommended in patients recei ving Deferasirox. In the presence of intercurrent processes, adequate hydration should be performed, and an early dose reduction or drug administration interruption should be considered in cases of kidney involvement.

Enterovirus A71 Infection and Neurologic Disease, Madrid, Spain, 2016

For children with brainstem encephalitis or encephalomyelitis, clinicians should look for enterovirus and not limit testing to cerebrospinal fluid.

We conducted an observational study from January 2016 through January 2017 of patients admitted to a reference pediatric hospital in Madrid, Spain, for neurologic symptoms and enterovirus infection. Among the 30 patients, the most common signs and symptoms were fever, lethargy, myoclonic jerks, and ataxia. Real-time PCR detected enterovirus in the cerebrospinal fluid of 8 patients, nasopharyngeal aspirate in 17, and anal swab samples of 5. The enterovirus was genotyped for 25 of 30 patients; enterovirus A71 was the most common serotype (21/25) and the only serotype detected in patients with brainstem encephalitis or encephalomyelitis. Treatment was intravenous immunoglobulins for 21 patients and corticosteroids for 17. Admission to the pediatric intensive care unit was required for 14 patients. All patients survived. At admission, among patients with the most severe disease, leukocytes were elevated. For children with brainstem encephalitis or encephalomyelitis, clinicians should look for enterovirus and not limit testing to cerebrospinal fluid.
