The impact of Covid-19 pneumonia caused by SARS-CoV-2 on transplanted populations under chronic immunosuppression seems to be greater than in normal population. Clinical management of the disease, particularly in those patients worsening after a cytokine storm, with or without allograft impairment and using available therapeutic approaches in the absence of specific drugs to fight against the virus, involves a major challenge for physicians. We herein provide evidence of the usefulness of high-dose intravenous immunoglobulin (IVIG) combined with steroid pulses to successfully treat a case of Covid-19 pneumonia in a single-kidney transplanted patient with mechanical ventilation and hemodialysis requirements in the setting of a cytokine storm. A rapid decrease in the serum level of inflammatory cytokines, particularly IL-6, IL-8, TNF-α, MCP-1 and IL-10, as well as of acute-phase reactants such as ferritin, D-dimer and C-reactive protein was observed after the IVIG infusion and methylprednisolone bolus administration with a parallel clinical improvement and progressive allograft function recovery, allowing the patient’s final discharge 40 days after the treatment onset. The immunomodulatory effect of IVIG together with the anti-inflammatory and immunosuppressive potential of steroids could be an alternative strategy to treat severe cases of Covid-19 pneumonia associated with an uncontrolled inflammatory response in transplanted populations.

RESUMEN La adenomatosis hepática es una enfermedad benigna definida por la aparición de múltiples adenomas en un hígado normal. Se trata de una entidad poco frecuente y de causa no conocida, de la que existen menos de un centenar de casos publicados en la literatura médica y que se ha relacionado con la toma de anticonceptivos orales o esteroides anabolizantes, con enfermedades por depósito y con mutaciones genéticas asociadas a la diabetes mellitus tipo MODY (maturity onset diabetes of the young). En los últimos años se ha comunicado la coexistencia de adenomatosis hepática con lesiones de esteatohepatitis no alcohólica en dos pacientes con síndrome metabólico, una asociación de interés por la creciente prevalencia de la enfermedad hepática grasa no alcohólica en los países desarrollados y por la posibilidad de que compartan un mecanismo causal. Comunicamos el caso de una mujer joven con fructosemia familiar y esteatosis hepática durante cuyo seguimiento aparecieron múltiples adenomas hepáticos asociados a lesiones de esteatohepatitis y discutimos el posible significado de dicha asociación.
