Ataxia with vitamin E deficiency in the Philippines†: A case report of two siblings.

Here we report two siblings with ataxia and peripheral neuropathy. One patient showed head tremors. Genetic analysis revealed a mutation in the hepatic α-tocopherol transfer protein (α-TTP) gene (TTPA) on chromosome 8q13. They were diagnosed with ataxia with vitamin E deficiency which is firstly reported in the Philippines. As the symptoms of ataxia with vitamin E deficiency can be alleviated with lifelong vitamin E administration, differential diagnosis from similar syndromes is important. In addition, ataxia with vitamin E deficiency causes movement disorders. Therefore, a common hereditary disease in the Philippines, X-linked dystonia-parkinsonism, could be another differential diagnosis. The Philippines is an archipelago comprising 7,107 islands, and the prevalence of rare hereditary diseases among the populations of small islands is still unclear. For neurologists, establishing a system of genetic diagnosis and counseling in rural areas remains challenging. These unresolved problems should be addressed in the near future. J. Med.

Hidden Hunger of Vitamin E among Healthy College Students: A Cross- Sectional Study.

BACKGROUND: College students may have a risk of fat-soluble vitamin deficiencies due to unhealthy dietary habits, especially for vitamin A and E. They are important members of the human antioxidant network; deficiencies of these vitamins may increase the risk of many critical diseases. OBJECTIVE: The current study was undertaken to determine the status of vitamin A and E in college students. METHODS: Healthy college students were recruited, and fasting blood samples of them were collected and used for determining serum levels of retinol and α-tocopherol by the HPLC method. RESULTS: We found that there was no vitamin A deficiency in college students. However, vitamin E deficiency existed in 34.5% of college students, especially in males. All the students had no vitamin E adequacy. In addition, our findings showed that BMI was inversely associated with serum α-- tocopherol, but not serum retinol. CONCLUSION: These results suggest that vitamin E deficiency in college students should be given more attention, and it is necessary to consider using vitamin E supplements.

A first description of ataxia with vitamin E deficiency associated with MT-TG gene mutation.

Ataxia with isolated vitamin E deficiency (AVED) is a rare autosomal recessive cerebellar ataxia disorder that is caused by a mutation in the alpha-tocopherol transfer protein gene TTPA, leading to a lower level of serum vitamin E. Although it is almost clinically similar to Friedreich's ataxia, its devastating neurological features can be prevented with appropriate treatment. In this study, we present a patient who was initially diagnosed with Friedreich's ataxia, but was later found to have AVED. Frataxin gene screening revealed the absence of GAA expansion in homozygous or heterozygous state. However, TTPAgene sequencing showed the presence of the c.744delA mutation, leading to a premature stop codon (p.E249fx). In addition, the result of mutational analysis of MT-DNA genes revealed the presence of several variants, including the m.10044A>G mutation in MT-TG gene. Here, we report for the first time the coexistence of both mitochondrial and nuclear genes mutations in AVED.

Vitamin A deficiency exacerbates extrinsic atopic dermatitis development by potentiating type 2 helper T cell-type inflammation and mast cell activation.

BACKGROUND: Vitamin A deficiency (VAD) has been hypothesized to play a role in the pathophysiology of atopic dermatitis (AD). OBJECTIVE: We sought to verify whether VAD can exacerbate AD development, and explore the possible pathophysiologic mechanism. METHODS: We detected serum vitamin A (VA) concentration in different phenotypes of AD infants (intrinsic AD, iAD and extrinsic AD, eAD), and established ovalbumin (OVA) percutaneous sensitized AD model and passive cutaneous anaphylaxis (PCA) model on VAD and vitamin A supplementation (VAS) model in wild-type mice (C57BL/6) and established AD model on both normal VA (VAN) and VAD feeding mast cell deficiency mice (ckitw-sh/w-sh ). RESULTS: The average serum VA concentration of eAD was significantly lower than that of iAD, as well as healthy controls. In OVA-induced C57BL/6 mouse AD model, compared with VAN group, VAD mice manifested significantly more mast cells accumulation in the skin lesions, more severe Th2-mediated inflammation, including higher serum IgG1 and IgE levels, more IL-4, IL-13 mRNA expression in OVA-sensitized skin, and lower Th1 immune response, including lower serum IgG2a and IFN-γ mRNA expression in the skin. But there was no significant difference in the expression of IL-17 mRNA between OVA-treated skin of VAN and VAD mice. However, in OVA-induced ckitw-sh/w-sh mouse AD model, we did not find any significant differences in the above measurements between VAD and VAN group. In PCA model, VAD mice showed remarkable more blue dye leakage than that in VAN mice. Compared with VAD group, the above-mentioned inflammatory measurements in VAS group and VAN group were similar in OVA-induced AD model mice. CONCLUSIONS AND CLINICAL RELEVANCE: VAD can exacerbate extrinsic AD by augmenting Th2-mediated inflammation and mast cell activation. Therapeutic VAS can rescue VAD-aggravated eAD. It may provide a new strategy for future prevention or treatment of atopic dermatitis.

Chronic Complications of Cholestasis: Evaluation and Management.

Patients with primary biliary cholangitis (PBC) are at risk for various harmful consequences of chronic cholestasis. These include fat-soluble vitamin deficiency, even in the setting of macronutrient sufficiency, as well as metabolic bone disease, including osteoporosis with fractures. Hyperlipidemia is often present and less commonly associated with risk of cardiovascular event; however, the long-term effect of new emerging therapies for PBC remains to be determined. Patients with PBC also have infrequent but notable risk of portal hypertension despite early-stage disease. This review discusses the background, evaluation, and practical management of these complications of chronic cholestasis.

Exocrine Pancreatic Insufficiency and Malnutrition in Chronic Pancreatitis: Identification, Treatment, and Consequences.

OBJECTIVES: The purpose of this study was to examine the impact of exocrine pancreatic insufficiency (EPI) on chronic pancreatitis (CP) patients and to identify challenges with its diagnosis and treatment. METHODS: Ninety-one patients with CP diagnosed with endoscopic ultrasound were identified and assessed for symptoms of EPI, fat-soluble vitamin levels, dual-energy x-ray absorptiometry scan T-scores, and treatment with pancreatic enzyme replacement therapy. All patients were also screened with the Malnutrition Universal Screening Test. RESULTS: Exocrine pancreatic insufficiency was diagnosed in 84.6% (77/91) of patients based on symptoms of bloating, steatorrhea, or weight loss. Of these patients, 35.2% (19/54) had vitamin A deficiency, 62.5% (55/88) had vitamin D deficiency, and 17.7% (9/51) had vitamin E deficiency. Either osteopenia or osteoporosis was found in 68.9% (31/45). A medium or higher risk for malnutrition based on Malnutrition Universal Screening Test score of 1 or higher was found in 31.5% (28/89). Malnutrition Universal Screening Test score of 1 or higher was associated with an increased risk for osteopenia and osteoporosis on Fisher's exact test (P = 0.0037). CONCLUSIONS: There is a high prevalence of fat-soluble vitamin deficiencies, osteopathy, and malnutrition in CP patients, which is underestimated due to a lack of effective diagnosis and suboptimal therapies for EPI.

Pigment retinopathy in warmblood horses with equine degenerative myeloencephalopathy and equine motor neuron disease.

OBJECTIVE: A pigment retinopathy has been reported in adult horses with equine motor neuron disease (EMND) arising from chronic α-tocopherol (α-TP) deficiency. A pigment retinopathy has not been identified in horses with neuroaxonal dystrophy/equine degenerative myeloencephalopathy (NAD/EDM) that affects genetically susceptible young horses with α-TP deficiency. The objective of this report is to describe, for the first time, a pigment retinopathy in a family of α-TP-deficient Warmbloods (WB) with clinically apparent NAD/EDM or EMND. ANIMALS AND PROCEDURES: Twenty-five WB horses from one farm underwent complete neurologic and ophthalmic examinations and serum α-TP concentrations were assessed. Two of the most severely ataxic horses were euthanized and postmortem examinations performed. RESULTS: Alpha-TP deficiency was widespread on this farm (22 of 25 horses). Eleven of 25 horses were clinically normal (age range 2-12 years), one had signs of EMND (6 years of age), 10 had signs of ataxia consistent with NAD/EDM (1-10 years), and two of these were postmortem confirmed concurrent NAD/EDM and EMND. A pigment retinopathy characterized by varying amounts of granular dark pigment in the tapetal retina was observed in four clinically apparent NAD/EDM horses (two postmortem confirmed concurrent NAD/EDM and EMND) and one horse with clinical signs of EMND. CONCLUSIONS: A pigment retinopathy can be present in young α-TP-deficient Warmblood horses with clinical signs of EMND as well as those with signs of NAD/EDM.

Association between maternal vitamin E status and alpha-tocopherol levels in the newborn and colostrum.

Vitamin E is important because of its antioxidant activity in situations of oxidative stress, especially postnatally. Hence, the objective was to verify whether maternal alpha-tocopherol level is associated with the alpha-tocopherol levels of the newborn and colostrum. This is a cross-sectional study of 58 women and their term newborns from a public hospital. Blood and colostrum were collected to measure alpha-tocopherol levels by high-performance liquid chromatography. Mothers with serum alpha-tocopherol levels <16.2 mmol L(-1) and newborns <11.6 mmol L(-1) were indicative of deficiency or low levels. Mothers were divided into two groups: <16.2 mmol L(-1) and those with levels ≥16.2 mmol L(-1) . The mean (95% confidence interval) serum alpha-tocopherol levels of mothers, umbilical cords and colostrum were 28 (24-32), 6 (5-8) and 39 mmol L(-1) (32-45), respectively (P < 0.001); 19% of the women and 90% of the newborns had low alpha-tocopherol levels. Maternal alpha-tocopherol level was associated with that of the umbilical cord. Newborns from mothers at risk of deficiency had low alpha-tocopherol levels (P < 0.001). Colostrum levels of vitamin E were not influenced by maternal serum. Maternal deficiency influenced the vitamin E level of the umbilical cord but does not in the colostrum, evidencing distinct transfer mechanisms via the mammary gland.

Nutritional status in children with Shwachman-diamond syndrome.

OBJECTIVE: In Shwachman-Diamond syndrome (SDS), pancreatic insufficiency can lead to malabsorption of fat-soluble vitamins and trace elements. The aim of this study was to assess the serum concentrations of vitamins A and E, zinc, copper, and selenium and their deficiencies. METHODS: This retrospective review was performed in 21 children (12 were male; median age, 7.8 years) with genetically confirmed SDS at a tertiary pediatric hospital. Pancreatic enzyme replacement therapy (PERT) and vitamin or trace elements supplements were documented. RESULTS: Twenty patients (95%) had pancreatic insufficiency receiving PERT, 10 (47%) had a combined vitamin and trace element deficiency, 6 (29%) had an isolated vitamin deficiency, and 4 (19%) had an isolated trace element deficiency. Vitamins A and E deficiency occurred in 16 (76%) and 4 (19%) of 21, respectively. Low serum selenium was found in 10 (47%), zinc deficiency in 7 (33%), and copper deficiency in 5 (24%). Eleven patients (52%) were on multivitamin supplementation, and 2 (10%) on zinc and selenium supplements. No statistical differences were found between repeated measurements for all micronutrients. CONCLUSIONS: More than 50% of the children had vitamin A and selenium deficiencies despite adequate supplementation of PERT and supplements. Micronutrients should be routinely measured in SDS patients to prevent significant complications.

Multiple vitamin deficiencies in a patient with a history of chronic alcohol excess and self-neglect in the UK.

We report a case of inadequate diet (caused by extreme self-neglect and alcohol excess) which led to chronic severe deficiencies of vitamins A, D and E. At presentation the patient had widespread follicular hyperkeratosis of the skin, keratomalacia of both eyes and a severe cognitive impairment. He responded well to treatment including high dose parenteral vitamins, but lasting impairments in his vision and cognition have caused permanent disability.

Fat-soluble vitamin deficiencies after bariatric surgery could be misleading if they are not appropriately adjusted.

OBJECTIVE: To evaluate the differences in frequency of fat-soluble vitamin deficiencies if we adjust their levels by its main carriers in plasma in patients undergoing Biliopancreatic diversion (BPD) and Roux-en-Y gastric bypass (RYGB). RESEARCH METHODS & PROCEDURES: We recruited 178 patients who underwent RYGB (n = 116 patients) and BPD (n = 62 patients) in a single centre. Basal data information and one-year after surgery included: anthropometric measurements, fat-soluble vitamins A, E and D, retinol binding protein (RBP) and total cholesterol as carriers of vitamin A and E respectively. Continuous data were compared using T-Student and proportions using chisquare test. RESULTS: There was a vitamin D deficiency of 96% of all patients, 10% vitamin A deficiency and 1.2% vitamin E deficiency prior to surgery. One year after surgery, 33% of patients were vitamin A deficient but the frequency reduced to 19% when we adjusted by RBP. We found a vitamin E deficiency frequency of 0% in RYGB and 4.8% in DBP one year after surgery. However, when we adjusted the serum levels to total cholesterol, we found an increased frequency of 8.7% in RYGB group for vitamin E deficiency and 21.4% in DBP (p = 0.04). CONCLUSION: We have found a different frequency of deficit for fat-soluble vitamin both in BPD and RYGB once we have adjusted for its main carriers. This is clinically relevant to prevent from overexposure and toxicity. We suggest that carrier molecules should be routinely requested when we assess fat-soluble vitamin status in patients who undergo malabsorptive procedures.

OBJETIVO: Evaluar las diferencias en la frecuencia de las deficiencias de vitaminas liposolubles si ajustamos sus concentraciones mediante sus principales transportadores plasmáticos en pacientes sometidos a derivación biliopancreática (DBP) y derivación gástrica en Y de Roux (DGYR). MÉTODOS DE INVESTIGACIÓN Y PROCEDIMIENTOS: Reclutamos a 178 pacientes sometidos a DGYR (n = 116 pacientes) y DBP (n = 62 pacientes) en un único centro. Los datos de información basal y al año de la cirugía incluyeron: mediciones antropométricas, vitaminas liposolubles A, E y D, proteína de unión al retinol (PUR) y el colesterol total como transportadores de las vitaminas A y E, respectivamente. Los datos continuos se compararon utilizando la t de Student y para las proporciones el test chi cuadrado. RESULTADOS: Hubo una deficiencia de vitamina D en el 96% de todos los pacientes, de vitamina A en el 10% y de vitamina E en el 1,2% antes de la cirugía. Un año después de la cirugía, el 33% de los pacientes tenía deficiencia de vitamina A pero la frecuencia se redujo al 19% cuando ajustamos para la PUR. Encontramos una frecuencia de deficiencia de vitamina E en el 0% de los pacientes con DGYR y en el 4,8% de aquellos con DBP un año después de la cirugía. Sin embargo, cuando ajustamos las concentraciones séricas de colesterol total, encontramos un aumento de la frecuencia de hasta el 8,7% de deficiencia de vitamina E en el grupo con DGYR y del 21,4% en el grupo con DBP (p = 0,04). CONCLUSIÓN: Encontramos una frecuencia diferente de déficit de vitaminas liposolubles tanto en DBP como en DGYR una vez que ajustamos para sus principales transportadores. Esto es clínicamente relevante para evitar la sobreexposición y la toxicidad. Sugerimos que se deberían solicitar de forma rutinaria las moléculas transportadoras a la hora de evaluar el estado de vitaminas liposolubles en pacientes sometidos a procedimientos que entrañan malabsorción.

Is it necessary to assess for fat-soluble vitamin deficiencies in pediatric patients with newly diagnosed celiac disease?

BACKGROUND: The purpose of this study was to identify the frequency of fat-soluble vitamin deficiencies in children with celiac disease (CD) and to determine the value of routine testing for these deficiencies. METHODS: We conducted a retrospective medical record review of patients with a confirmed diagnosis of CD and fat-soluble vitamin levels measured at diagnosis between 1995 and 2012 at Mayo Clinic. Patients' demographics, fat-soluble vitamin levels, and pertinent clinical factors at the time of diagnosis were collected. RESULTS: Eighty-three patients were included in the final analysis: 51 girls and 32 boys, with an average age at diagnosis of 12.8 years in girls and 13.0 years in boys. The most commonly reported symptoms were abdominal pain in 49 patients and diarrhea in 30 patients. Family history of CD was reported in 32 patients. Average vitamin levels for vitamin E, 25-hydroxyvitamin D (25 (OH) D), and vitamin A were 7.5 mg/L, 32.8 ng/mL, and 334.5 µg/dL, respectively. No patients had vitamin A deficiency, 2 patients had vitamin E deficiency, and 9 patients had mild-to-moderate vitamin D deficiency (none had severe deficiency). Both patients with vitamin E deficiency were symptomatic and had complete villous atrophy. Thirty-one patients had insufficiency of 25 (OH) D, which was less than the reported frequency of vitamin D insufficiency in the general pediatric population in the United States in 2004. None of the patients were receiving vitamin supplements at the time of diagnosis. CONCLUSIONS: Fat-soluble vitamin deficiencies are uncommon in children with new diagnosis of CD. Routine measuring of fat-soluble vitamins levels may not be necessary.

Brown bowel syndrome: a rare complication in diseases associated with long-standing malabsorption.

BACKGROUND/AIMS: Longtime chronic malabsorption may among other things cause a lack of liposoluble vitamins. Vitamin E deficiency can lead to formation of lipofuscin aggregates. Its deficiency is also associated with an increased lipofuscinosis of the bowel, i.e. brown bowel syndrome. METHODS: Systematic research via Medline on brown bowel syndrome, lipofuscinosis, and vitamin E deficiency was performed. We combined our own clinical experience and a review of the literature for this paper. Its goal is to inform about the possible consequences of severe malabsorption and brown bowel syndrome. RESULTS: Systematic data about the occurrence of severe malabsorption and brown bowel syndrome are rare. Only about 27 scientific reports can be found on this subject. Brown bowel syndrome is found mostly in conjunction with vitamin E deficiency and lipofuscinosis of the bowel. The clinical findings are caused by both malabsorption and lipofuscinosis. Case reports show a therapeutic effect of vitamin E. CONCLUSION: Vitamin deficiency caused by longtime chronic malabsorption can lead to the development of brown bowel syndrome, which is seen as the expression of lipofuscinosis of the bowel, and can cause further clinical disorders. Patients with malabsorption should therefore be monitored regarding their vitamin E levels.
