“…The erythrocyte thiamine diphosphate level assessed by high-pressure liquid chromatography is found to be a better marker of thiamine deficiency. [10] Furthermore, the characteristic MRI findings in our case of hyperintensity on FLAIR and T2-weighted images in the periaqueductal area have high specificity and moderate sensitivity in the diagnosis of WE.

Wernicke's encephalopathy (WE) is a potentially fatal neuropsychiatric syndrome precipitated by thiamine deficiency due to a variety of causes such as chronic severe alcoholism, starvation, and prolonged intravenous feeding. WE has also been observed rarely in the clinical setting of hyperemesis gravidarum. Here, we report the case of a 34-year-old pregnant woman who presented with reduced vision, gaze-evoked nystagmus, and postural imbalance preceded by 2 weeks of hyperemesis. Fundus examination showed features consistent with papillitis. Magnetic resonance imaging (MRI) showed T2WI, FLAIR, and diffusion-weighted imaging MR images showing hyperintensity in dorsomedial thalami and periaqueductal grey matter with diffusion restriction. She was diagnosed with WE based on history, clinical examination findings, and MRI findings and was treated with injectable thiamine. She showed marked improvement in vision and nystagmus within 3 days. Our case is a rare presentation of WE in a pregnant woman with hyperemesis gravidarum.

“…Most cases of optic disc swelling caused by thiamine deficiency (90%; 36/40) [ 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 ] were young women (mean age = 28 years, range = 11–56 years), matching the typical demographic of IIH patients ( Table 2 and Tables S5 and S6 ). The cause of thiamine deficiency was predominately due to reduced intake (62.5%; 25/40) due to anorexia, nausea, vomiting or restrictive diets.…”

Micronutrient Deficiencies Presenting with Optic Disc Swelling Associated with or without Intracranial Hypertension: A Systematic Review

et al. 2022

View full text Add to dashboard Cite

Idiopathic intracranial hypertension (IIH) is a neurological disorder characterised by optic disc swelling secondary to raised intracranial pressure (ICP) of unknown cause. Obesity is the most established and prevalent risk factor in developed countries. As obesogenic diets are high in calories and nutrient-poor, there may be associated nutritional deficiencies that contribute to the clinical presentation of IIH. Yet none, aside from iron deficiency, are currently included in the inclusion or exclusion criteria for the diagnosis of IIH. Our primary aim was to determine which micronutrient deficiencies, aside from iron deficiency, could present with optic disc swelling associated with or without intracranial hypertension that could potentially meet current IIH diagnostic criteria. To this end, we conducted a systematic search of articles published between 1 January 1980 and 18 December 2020 reporting cases of optic disc swelling associated with micronutrient deficiencies. In total, 65 cases met the eligibility criteria from initial searches: all were case reports and case series with a high risk of bias. Our findings suggest that patients with IIH or unexplained optic disc swelling ought to be screened, investigated, and treated for associated micronutrient deficiencies in vitamin A, B1 and B12; and weight loss interventions in IIH patients ought to promote better nutrition in addition to overall calorie restriction.
