Association of Adrenal Insufficiency With Pediatric Pseudotumor Cerebri Syndrome.

ABSTRACT:

Importance

Pediatric pseudotumor cerebri syndrome pathophysiology is complex and not well delineated. Therefore, it is important to identify potential contributors or targets underlying the primary pathogenesis for its development.

Objective

To report cases highlighting the association of pediatric pseudotumor cerebri syndrome with adrenal insufficiency.

Design, setting, and participants

This noncontrolled, observational case series included pediatric patients diagnosed with pseudotumor cerebri syndrome and adrenal insufficiency at an urban academic children's hospital in Houston, Texas, from June 2015 to October 2019.

Main outcomes and measures

Monitoring optic nerve edema by clinical examination, fundus photography, and optical coherence topography images of the optic nerve.

Results

Data were collected from 5 pediatric patients (age range, 5-10 years) diagnosed with pseudotumor cerebri syndrome and adrenal insufficiency. One was a girl; all were White and prepubertal. Three patients had unrecognized glucocorticoid exposure. All patients had bilateral optic nerve edema that was initially treated with acetazolamide or topiramate, but cortisol functional testing by either 8 am cortisol or cosyntropin stimulation tests revealed a diagnosis of central adrenal insufficiency. Treatment with physiological doses of hydrocortisone resulted in resolution of optic nerve edema and clinical symptoms of pseudotumor cerebri syndrome, as well as a shorter time receiving medical therapy.

Conclusions and relevance

In this case series, adrenal insufficiency was associated with both primary and secondary prepubertal pediatric pseudotumor cerebri syndrome. As a potential target specific to causative mechanism, physiologic hydrocortisone therapy resolved the condition. To date, there remains a global unawareness among clinicians about the suppressive outcome that glucocorticoids may have on the developing hypothalamic-pituitary-adrenal axis, resulting in adrenal insufficiency and so-called episodic pseudotumor cerebri syndrome in young children. Ophthalmologists and pediatric subspecialists should implement cortisol testing via either 8 am cortisol or cosyntropin stimulation tests at initial evaluation of all children with pseudotumor cerebri syndrome and risk factors for adrenal insufficiency, no predisposing causes, or nonresponse to conventional treatment. Further management and treatment should be in combination with ophthalmology and endocrine services.

Project description:BackgroundIn patients with adrenal insufficiency (AI), adrenal crisis (AC) represents a clinical emergency. Early recognition and prompt management of AC or AC-risk conditions in the Emergency Department (ED) can reduce critical episodes and AC-related outcomes. The aim of the study is to report the clinical and biochemical characteristics of AC presentation to improve their timely recognition and proper management in a ED setting.MethodsSingle-centre, retrospective, observational study on pediatric patients followed at the Department of Pediatric Endocrinology of Regina Margherita Children's Hospital of Turin for primary AI (PAI) and central AI (CAI).ResultsAmong the 89 children followed for AI (44 PAI, 45 CAI), 35 patients (21 PAI, 14 CAI) referred to the PED, for a total of 77 accesses (44 in patients with PAI and 33 with CAI). The main causes of admission to the PED were gastroenteritis (59.7%), fever, hyporexia or asthenia (45.5%), neurological signs and respiratory disorders (33.8%). The mean sodium value at PED admission was 137.2 ± 1.23 mmol/l and 133.3 ± 1.46 mmol/l in PAI and CAI, respectively (p = 0.05). Steroids administration in PED was faster in patients with CAI than in those with PAI (2.75 ± 0.61 and 3.09 ± 1.47 h from PED access, p = 0.83). Significant factors related to the development of AC were signs of dehydration at admission (p = 0.027) and lack of intake or increase of usual steroid therapy at home (p = 0.059). Endocrinological consulting was requested in 69.2% of patients with AC and 48.4% of subjects without AC (p = 0.032).Conclusionchildren with AI may refer to the PED with an acute life-threatening condition that needs prompt recognition and management. These preliminary data indicate how critical the education of children and families with AI is to improve the management at home, and how fundamental the collaboration of the pediatric endocrinologist with all PED personnel is in raising awareness of early symptoms and signs of AC to anticipate the proper treatment and prevent or reduce the correlated serious events.

Project description:  Pseudotumor cerebri (PTC) patients exhibit clear clinical signs and symptoms of higher intracranial pressure (ICP) without ventricular enlargement or mass lesions. The clinical picture of patients with PTC can sometimes be similar to that of Chiari Malformation type I (CMI). There is some evidence that Chiari I malformation and PTC may coexist, which raises the question of whether PTC is an idiopathic disease or a complication of posterior decompression surgery-treatment of choice for Chiari I malformation.A retrospective review of electronic medical records of patients diagnosed with PTC at the University of Toledo Medical Center (UTMC) was performed. The objective was to determine whether PTC patients had a concurrent diagnosis of Chiari I malformation and whether the diagnosis of PTC occurred before or after posterior decompression surgery. Out of the 8 eligible patient medical records reviewed, 5 patients diagnosed with PTC had undergone posterior decompression surgery for Chiari I malformation at anywhere from several days to three years prior to being diagnosed with PTC. The diagnosis of PTC was based on temporary symptomatic relief following lumbar puncture which also showed elevated CSF opening pressures. Finally, a VP shunt was placed in each of the 5 patients to relieve the elevated intracranial pressure which resulted in the complete resolution of the patients' symptoms.Our study focuses on patients who were diagnosed with and treated for CMI then reported back to the clinic within several days to three years complaining of symptoms of headache. Upon re-presenting to the clinic, a CSF flow study was performed which showed normal flow of CSF. Then, these patients underwent a lumbar puncture which demonstrated an elevated opening pressure (and ICP) and a temporary relief of the headache with lumbar drainage. A VP shunt was placed for each patient to treat for PTC, and the patients' headaches were relieved.This study suggests that the presence of Chiari I malformation in a patient conceals the symptoms of PTC which may become apparent following posterior decompression surgery. Other possibilities could be that the patients are misdiagnosed for Chiari I malformation when they are in fact suffering from PTC, or that PTC is a complication of surgery.
