1/3. Echovirus 7 infection and necrotizing enterocolitis-like symptoms in a premature infant.Echovirus type 7 has been previously recognized as a virulent serotype in the premature neonate. However, reports of fatal disseminated infections have often been perinatally acquired from symptomatic mothers at the time of delivery. Nosocomial outbreaks in full-term and premature infants have been reported from newborn intensive care units; however, deaths attributed to Echovirus 7 in convalescing prematures are rare in the literature. We report the case of a growing premature neonate presenting with an overwhelming sepsis-like syndrome, including symptoms consistent with necrotizing enterocolitis. Despite intensive supportive care including ventilatory support, cardiovascular pharmacotherapy, and blood product administration, the infant succumbed to overwhelming Echovirus 7 infection.- - - - - - - - - - ranking = 1keywords = administration (Clic here for more details about this article) |
2/3. Successful treatment of echovirus meningoencephalitis in sex-linked agammaglobulinaemia by intrathecal and intravenous injection of high titre gammaglobulin.A 7-year-old boy with sex-linked agammaglobulinaemia developed meningoencephalitis caused by echovirus type 11. He had convulsions, right hemiplegia, cortical motor aphasia, left abducens nerve paralysis, left hypoglossal nerve paralysis, and later became unconscious. Treatment by intravenous injection of conventional gammaglobulin and intrathecal alpha-interferon brought no clinical improvement, but intrathecal administration together with intravenous injection of gammaglobulin containing a high titre of anti-echovirus type 11 antibody was associated with a dramatic improvement in his clinical symptoms. After subsequent periodical (once or twice a week) administration of specific gammaglobulin for 8 months, the echovirus in his cerebrospinal fluid was no longer detected. These findings suggest that intrathecal injection combined with intravenous injection of high titre anti-echovirus type 11 antibody was effective in treating this case of echovirus meningoencephalitis in sex-linked agammaglobulinaemia.- - - - - - - - - - ranking = 2keywords = administration (Clic here for more details about this article) |
3/3. Echovirus meningomyeloencephalitis with administration of intrathecal immunoglobulin.Echovirus meningomyeloencephalitis was treated with cerebral intraventricular immunoglobulin. This case includes a complete examination of the central nervous system (CNS) supported by viral culture studies, immunoperoxidase staining and electron microscopy. Neuronal loss was most severe in the cerebellum and spinal cord. This may lead to the ataxia and a poliomyelitis-like syndrome often seen in cases of echovirus meningomyeloencephalitis. Focal encephalitic lesions, antigen-antibody reactions and live virus were found at numerous levels of the CNS in spite of intrathecal and intravenous immunoglobulin therapy. This mode of therapy and the electron microscopic features noted in echovirus infections are discussed.- - - - - - - - - - ranking = 4keywords = administration (Clic here for more details about this article) |
