Epidemiology of Endocrine Dysfunctions in Pediatric Patients with Previous Central Nervous System Infection: A Scoping Review of the Literature.

Purpose The incidence of endocrine sequelae following central nervous system (CNS) infections in pediatric age is not known. We conducted this scoping review to assess the incidence of endocrinological alterations in patients with prior CNS infections in pediatric age. Methods Our screening process included both randomized and non-randomized controlled trials. All types of observational studies, prospective and retrospective, have been included. Results Ten studies were included in our review. The cumulative number of patients in all of the studies was 211, the mean age of the population study was 4.9 (±5 years). The included papers described the following acute CNS infections: meningitis (nine studies reported eighty-five cases) and encephalitis (three studies described sixty-five cases). Two case reports and one retrospective study reported hypopituitarism as a consequence of Mycobacterium tuberculosis CNS infection. In five studies the patients developed endocrine comorbidities at the time of infection. Another study analyzed 49 young adults who previously had tuberculous meningitis at a mean age of 5.9 ± 5.0 years: seven patients had growth hormone deficiency, four of whom also had gonadotropin deficiency; the other three had gonadotropin deficiency, corticotropin deficiency, and mild hyperprolactinemia. Conclusion Standardized multidisciplinary follow-up and research of patients with prior CNS infection is crucial. Although pituitary reserve screening is not commonly performed in these patients, clinical and research centers should set up an endocrinological evaluation with monitoring of auxological parameters to detect the signs and symptoms of hypopituitarism early and to initiate the appropriate care in children with previous CNS infections.
