Our study was born from the observation of a clinical case of a boy who arrived in the Emergency Room of our hospital for persistent hyperpyrexia, headache and prolonged emetic episodes and complaining of objective photophobia and dizziness. The patient underwent haematochemical tests, chemical-physical examination of Chronic Fatigue Syndrome (CFS), negative for bacteria, negative for Neisseria Meningitidis, Escherichia Coli 121, Haemophilus Influenzae, Stafilococcus Pneumoniae, Stafilococcus Agalactiae and with slightly positive reaction to Pandy’s test; he was subjected to neurological examination, to Nuclear Magnetic Resonance of the brain and encephalic trunk with contrast agent which resulted negative, and to EEG that showed a slightly slowed-down brain electrical activity, in right occipital region, and frontal irritative abnormalities. Given these clinical and instrumental investigations, an acute meningoencephalitis was diagnosed. During his hospitalization, the patient was treated with intravenous antibiotic therapy and intravenous antiviral therapy for 12 days. At discharge, in the absence of specific therapy, and considering the protraction of the cephalic, dizzying, asthenic and myalgic symptoms and in relation to hematochemical and serological tests (positive for antibodies to Herpes 1 IgG), Epstein Barr Virus antibodies (positive for Viral Capsid Antigen IgG and IgGE BNA, for Extractable Nuclear Antigen and IgG Cytomegalovirus) he was diagnosed a Post-infectious CFS. The patient was treated with Oxygen Ozone Rectal Insufflative Therapy on a bi-weekly basis for 4 weeks, associated with Micetrin, a dietary supplement with sweetener based on Vitamin C, Shitake, Reishi, Maitake, Cordyceps, Magnesium and SOD, continued the treatment on a weekly basis for a further 4 weeks until the complete remission of the symptoms of asthenic, neurological and clinical parameters.
