RESUMO
Cunninghamella spp. is a group of fungi belonging to the Mucorales order. Cases of fungal endocarditis are sporadic, but more frequent in immunocompromised patients. COVID-19 (SARS-CoV-2 Infection Disease 2019) infections, prematurity, deferoxamine treatment, iron overload, neutropenia, diabetes, and malignant hemopathies proved to be risk factors for mucormycosis. We present the case of a 7-year-old boy who was treated every three weeks with blood transfusion for major beta-thalassemia, receiving deferoxamine for secondary hemochromatosis. After two weeks with nonspecific respiratory and digestive symptoms, he was admitted for fever, followed by lower limb ischemia and neurological signs. Echocardiography revealed massive endocarditis affecting the mitral and tricuspid valves with embolization phenomena in the brain, lungs, kidney, spleen, and lower limbs. As a particular finding, IgG antibodies for COVID-19 were positive. Emergency cardiac surgery was performed. The mitral valve necessitated replacement with CarboMedics prosthesis. Unfortunately, the patient did not survive. Cunninghamella spp. was confirmed via the PCR analysis of vegetations. Cunninghamella endocarditis in the context of a systemic infection presented as an opportunistic infection affecting a child who had several risk factors. Mucormycosis is challenging to treat, with high mortality. Prophylactic treatment in beta-thalassemia patients with iron-chelator deprivation drugs, such as deferiprone, may help in preventing these particular fungal infections.
RESUMO
BACKGROUND: To date, information on COVID-19 pediatric patients is still sparse. We aimed to highlight the epidemiological and clinical data regarding SARS-CoV-2 infection in children and adolescents to improve the understanding of the disease in this age group and inform physicians during the ongoing COVID-19 pandemic. METHODS: We conducted a retrospective, observational study in "Marie Curie" Emergency Children's Hospital from Bucharest, Romania. We analyzed clinical and epidemiological characteristics of the patients confirmed with SARS-CoV-2 infection, between April 1, 2020-October 31, 2020. RESULTS: A total of 172 patients aged 0-18 years were included, 79 (45.93%) female and 93 (54.07%) male patients. 28 (16.28%) patients had co-morbidities (more often identified in asymptomatic group; p < 0.0001). 47 (27.32%) had exposure to an identified source. 30 (17.44%) patients were asymptomatic; 142 (85.56%) had mild or moderate disease. The most frequent symptoms were: pyrexia (78.87%), digestive symptoms (50%), cough (40.14%). Chest X-ray was performed in 50 patients and it was abnormal in half of them, all being symptomatic. About 2/3 of the evaluated patients had normal leukocytes. The most common hematological change was lymphopenia; monocytes tended to be higher in symptomatic patients. About 40% of the patients were admitted; none required admission to ICU. No significant differences were found between symptomatic and asymptomatic patients regarding gender, age distribution, and exposure to a source. CONCLUSIONS: All the patients had asymptomatic, mild or moderate disease. Patients with comorbidities, classically considered high risk patients, presented the same pattern of disease.
