ABSTRACT
Subsequent to mass vaccination programs against COVID-19, diverse side effects have been described, both at the injection site, such as pain, redness and swelling, and systemic effects such as fatigue, headache, muscle or joint pain. On rare occasions, a lymphadenopathic syndrome may develop, raising the clinical suspicion of a lymphoproliferative disorder. We present the case of a 30-year-old woman who developed self-limiting left axillary lymphadenopathy following COVID-19 vaccination. To date, only seven similar cases with a complete clinicopathological description have been published, and fourteen cases have been notified to the European adverse events databases (Eudravigilance) in relationship with vaccination against COVID-19. It is important to be aware of this potential complication when a lymphadenopathic syndrome develops following vaccination, to avoid unnecessary treatment. (AU)
Tras la vacunación masiva frente a la COVID-19 se han comenzado a describir diversos efectos adversos incluyendo efectos locales en el lugar de la inyección, como dolor, enrojecimiento, hinchazón, etc., y efectos sistémicos como fatiga, dolor de cabeza, dolor muscular o articular. Más infrecuentemente se pueden desarrollar cuadros linfadenopáticos sospechosos clínicamente de proceso linfoproliferativo. Presentamos el caso de una mujer de 30 años que desarrolló linfadenopatía axilar izquierda tras la vacunación contra la COVID-19 con hallazgos histopatológicos de linfadenopatía necrotizante de tipo Kikuchi y resolución espontánea. Hasta el momento se han publicado 7 casos con descripción clinicopatológica completa en la literatura y notificado 14 casos en la Red Europea de Farmacovigilancia en relación con la vacunación. Es importante tener en cuenta esta entidad en linfadenopatías sospechosas de procesos linfoproliferativos en este contexto, para evitar un tratamiento innecesario. (AU)

The steady-state pharmacokinetics of an ultralong sustained release formulation of theophylline (Unilong) twice daily (bid) in elderly hospitalized patients suffering from chronic obstructive pulmonary disease (COPD) have been studied in order to establish guidelines for monitoring. The study was carried out in 37 patients (33 men), aged 60-87 years. Samples were collected from 0 to 12 h after the morning dose on day 9 of treatment with 250 mg bid (n=25) or 375 mg bid (n=12). Considerable variability in apparent clearance (range 0.33-1.49 ml/min per kg of ideal body weight), Css(min)/D (range 0.28-1.86), Css(max)/D (range 0.65-2.33) and (Css(max)-Css(min))/Css(avg) (range 0.18-0.80) was observed. There was no significant correlation between the patient's age and apparent clearance within this elderly population. The concentration-to-dose ratio and the relationship between the steady-state plasma concentration at different times during the dosage interval and Css(avg) are described. It is concluded that the interpatient variability in peak-trough fluctuation of this formulation was higher than that described in healthy volunteers by other investigators, and that the apparent clearance did not decrease with age within this elderly population with COPD. The importance of theophylline monitoring is emphasized and rules to estimate Css(avg) and Css(5h) from Css(0h) when only a single sample obtained before the morning dose is available are given.
