ABSTRACT
La viruela símica (monkey pox) es una enfermedad infecciosa causada por un virus del género Orthopoxvirus, usualmente acompañada de síntomas sistémicos como: fiebre, cefalea, mialgias, astenia, erupciones cutáneas o lesiones mucosas. Esta enfermedad se transmite por contacto físico con personas infectadas, materiales o animales infectados. Presentamos el caso de un paciente de 6 años que acude a consulta de Atención Primaria por presentar sintomatología compatible con esta sospecha clínica. Se diagnostica viruela símica bajo reacción en cadena de la polimerasa (PCR) positiva y se da de alta con manejo sintomático ambulatorio. (AU)
Monkeypox is a zoonosis-type disease caused by a virus of the genus Orthopoxvirus. Usually accompanied by systemic symptoms such as fever, headache, myalgia, asthenia, skin rashes or mucosal lesions. This disease is transmitted by physical contact with infected people, infected materials or animals. We present the case of a 6-year-old patient who came to primary care for symptoms compatible with clinical suspicion. Monkeypox was diagnosed under positive PCR and discharged with outpatient symptomatic management. (AU)

Fucoidan is a polysaccharide obtained from marine brown algae, with anti-inflammatory, anti-viral, and immune-enhancing properties, thus, fucoidan may be used as an alternative treatment (complementary to prescribed medical therapy) for COVID-19 recovery. This work aimed to determine the ex-vivo effects of treatment with fucoidan (20 µg/mL) on mitochondrial membrane potential (ΔΨm, using a cationic cyanine dye, 3,3'-dihexyloxacarbocyanine iodide (DiOC6(3)) on human peripheral blood mononuclear cells (HPBMC) isolated from healthy control (HC) subjects, COVID-19 patients (C-19), and subjects that recently recovered from COVID-19 (R1, 40 ± 13 days after infection). In addition, ex-vivo treatment with fucoidan (20 and 50 µg/mL) was evaluated on ΔΨm loss induced by carbonyl cyanide 3-chlorophenylhydrazone (CCCP, 150 µM) in HPBMC isolated from healthy subjects (H) and recovered subjects at 11 months post-COVID-19 (R2, 335 ± 20 days after infection). Data indicate that SARS-CoV-2 infection induces HPBMC loss of ΔΨm, even 11 months after infection, however, fucoidan promotes recovery of ΔΨm in PBMCs from COVID-19 recovered subjects. Therefore, fucoidan may be a potential treatment to diminish long-term sequelae from COVID-19, using mitochondria as a therapeutic target for the recovery of cellular homeostasis.
