Mielopatía por déficit de cobre: serie de casos y revisión de la literatura / Myelopathy due to copper deficiency: A case series and review of the literature

El déficit de cobre puede presentarse como una mielopatía y manifestarse como una ataxia sensorial secundaria a una desmielinización de los cordones posteriores de la médula espinal. Puede acompañarse de citopenias, principalmente anemia y leucopenia. Se presenta una serie de casos de tres pacientes con mielopatía por déficit de cobre, diagnosticados y manejados desde el año 2020 al 2022 en un hospital universitario de alta complejidad en Colombia. Dos de los casos eran mujeres. El rango de edad fue entre 57 y 68 años. En los tres casos, los niveles séricos de cobre estaban disminuidos y en dos de ellos, se descartaron diferentes causas de mielopatía que afectan los cordones posteriores de la médula espinal como el déficit de vitamina B12, vitamina E y ácido fólico, tabes dorsal, mielopatía por virus de la inmunodeficiencia humana, esclerosis múltiple e infección por el virus linfotrópico humano de tipo I y II, entre otras. Sin embargo, un paciente tenía deficiencia de vitamina B12 asociada con de cobre en el momento del diagnóstico de la mielopatía. En los tres casos hubo ataxia sensitiva y en dos, la paraparesia fue el déficit motor inicial. Se deben incluir siempre la determinación de los niveles de cobre dentro del abordaje diagnóstico de todo paciente con enfermedad gastrointestinal crónica, con diarrea crónica, síndrome de mala absorción o reducción significativa de la ingestión en la dieta, y que desarrolle síntomas neurológicos sugestivos de compromiso de los cordones, ya que se ha reportado que el retraso en el diagnóstico de las mielopatías se asocia con pobres desenlaces neurológicos.

Copper deficiency can present as myelopathy by the manifestation of sensory ataxia, secondary to demyelination of the posterior cords of the spinal cord, accompanied by cytopenia, mainly anemia, and leukopenia. Case series study of three patients with myelopathy due to copper deficiency, diagnosed and managed from 2020 to 2022 in a highly complex university hospital in Colombia. Regarding gender, two cases were female patients. The age range was between 57 and 68 years. In all three cases serum copper levels were decreased, and in two of these, different causes of myelopathy affecting the posterior cords of the spinal cord were ruled out, such as vitamin B12, vitamin E and folic acid deficiency, tabes dorsalis, myelopathy due to human immunodeficiency virus, multiple sclerosis and infection by the human lymphotropic virus type I and II, among others. However, at the moment of the myelopathy diagnosis, one patient had vitamin B12 deficiency associated with copper insufficiency. All three cases presented sensory ataxia, and in two, paraparesis was the initial motor deficit. The diagnostic approach must include copper levels assessment in every case of patients with chronic gastrointestinal pathology, chronic diarrhea, malabsorption syndrome, or significant reduction in dietary intake; and the development of neurological symptoms that may suggest cord involvement. It has been reported that a delay in diagnosis can lead to poor neurological outcomes.

Microvillus inclusion disease: a case report and literature review / 中华围产医学杂志

Objective:To investigate the clinical features and genetic mutations of microvillus inclusion disease (MVID).Methods:Clinical features and gene sequencing results of a neonate with MVID in Children's Hospital of Chongqing Medical University in August 2019 were retrospectively analyzed. Literature was retrieved up to October 2021, with the terms of microvillus inclusion disease, congenital microvilli atrophy, MVID, MYO5B, STX3, and STXBP2 in China National Knowledge Infrastructure, Wanfang Database, VIP database, and PubMed. Clinical features, diagnosis, and treatment of the reported MVID cases were reviewed. Results:(1) Case report: A male infant presented with jaundice two days after birth and was admitted to our hospital. Clinical features included intractable diarrhea, intermittent abdominal distension, uncorrectable dehydration, and weight loss. Laboratory test results indicated metabolic acidosis, electrolyte disorder, and cholestasis. Whole exome sequencing confirmed the diagnosis of MVID in this baby boy with compound heterozygous mutations of c.1021C>T(p.Q341*) and c.1125G>A(p.W375*) in the MYO5B gene, which were inherited from the father and the mother, respectively. (2) Literature review: Except for the present case, 31 patients from 20 articles were reviewed, and the typical clinical manifestations were intractable diarrhea, accompanied by dehydration, metabolic acidosis, electrolyte disorder, etc. Some patients also developed extra-gastrointestinal symptoms, including feeding difficulties and malnutrition (8/18), respiratory distress syndrome (4/18) and jaundice/cholestasis (4/18) in patients with MYO5B mutations; feeding difficulties and malnutrition (2/5), respiratory distress syndrome (1/5), and sepsis (1/5) in patients with STX3 mutations; feeding difficulties (2/9), respiratory distress syndrome (1/9), jaundice/cholestasis (1/9), sepsis (1/9), and hypoglycemia (1/9) in patients with STXBP2 mutations. In terms of the demographic data and prenatal examination, preterm birth (8/18), fetal bowel dilatation (5/18), polyhydramnios (5/18), parental consanguinity (2/18), and meconium-stained amniotic fluid (2/18) occurred among patients with MYO5B mutations. In those with STX3 mutations, parental consanguinity (3/5), fetal bowel dilatation (1/5), polyhydramnios (1/5), and meconium-stained amniotic fluid (1/5) occurred. Of nine patients with STXBP2 mutations, parental consanguinity (3/9), preterm birth (2/9), and polyhydramnios (2/9) occurred. Conclusions:MVID has atypical clinical features and a high mortality, resulting in difficulty in the diagnosis and treatment. The possibility of MVID should be considered when an infant presents with intractable diarrhea, dehydration, metabolic acidosis, and electrolyte disorder accompanied by multiple extra-gastrointestinal symptoms. Early identification of MYO5B, STX3, and STXBP2 mutations will benefit prompt intervention, prognosis evaluation, and genetic counseling.

Hipotiroidismo refractario idiopático: un caso clínico / Idiopathic refractory hypothyroidism: case report

Introducción: El hipotiroidismo constituye una patología frecuente, y su tratamiento habitual es el suplemento de levotiroxina (LT4) oral (VO). Sin embargo, existen casos inhabituales donde no es posible corregir esta condición a pesar de la utilización de LT4 en dosis alta. El hipotiroidismo refractario se define como la persistencia del hipotiroidismo a pesar del uso de LT4 > 1,9 ug/kg/día. La prevalencia del hipotiroidismo refractario no ha sido suficientemente documentada hasta ahora. Descripción del caso: Mujer de 53 años con antecedentes de hipotiroidismo, obesidad, dislipidemia, hipertensión arterial e insulinorresistencia. Fue derivada desde APS a nivel terciario por hipotiroidismo persistente a pesar del uso de LT4 800 ug/día y liotironina 80 ug/día. En forma ambulatoria se descartaron distintas causas, como mala adhesión al tratamiento, pseudo-malabsorción, síndromes de malabsorción; interacciones farmacológicas o interacciones alimentarias. Ante esto, y manteniéndose en su condición, se decide hospitalizar. Durante la hospitalización se prueban distintas fórmulas de administración. Finalmente, se logra respuesta adecuada con LT4 por vía rectal 100 ug/día asociado a 100 ug c/12 horas VO. Discusión: A pesar de no contar con herramientas óptimas para enfrentar este caso, se logró aplicar una estrategia sistemática especializada, que permitió un buen manejo de la paciente. Luego de probar distintas formulaciones de hormonas tiroideas, se logró respuesta mediante la administración por vía rectal, lo cual sugiere que esta paciente presentaba algún trastorno celular/bioquímico intestinal alto, que impedía la absorción óptima de LT4 VO. Conclusiones: La principal fortaleza de este trabajo consiste en la demostración de la utilidad práctica, en un contexto de recursos limitados, de una estrategia de estudio y tratamiento sistemático del hipotiroidismo refractario, lo cual ha sido escasamente publicado en la literatura internacional. Además, se recalca la importancia de una intervención especializada oportuna para evitar los riesgos sistémicos asociados a dosis altas de hormonas tiroideas.

Introduction: Hypothyroidism is a common condition, and its usual treatment is the supplement of oral levothyroxine (po). However, there are unusual cases where it is not possible to correct this condition despite the use of high-dose levothyroxine. Refractory hypothyroidism is defined as the persistence of hypothyroidism despite the use of levothyroxine > 1.9 ug/kg/ day. The prevalence of refractory hypothyroidism has not been sufficiently documented so far. Case description: 53 year old woman with a history of hypothyroidism, obesity, dyslipidemia, hypertension and insulin resistance. She was sent from primary care to tertiary level due to persistent hypothyroidism despite the use of 800 ug/day levothyroxine and liothyronine 80 ug/ day. On an outpatient basis, different causes were excluded as poor adherence to treatment, pseudo-malabsorption, malabsorption syndromes; drug interactions or food interactions. Given this, and staying on her condition, it was decided to hospitalize. Different forms of administration were tested during hospitalization. Finally, got adequate response with levothyroxine rectally 100 ug/day associated with 100 ug po bid. Discussion: Despite not having optimum tools to deal with this case, it was succeeded thanks to the implementation of a specialized systematic strategy. After testing different formulations of thyroid hormones, a positive response by rectal administration was achieved, which suggests that this patient presented any high intestinal cell/biochemist disorder that prevented the optimal absorption of levothyroxine po. Conclusions: The main strength of this work consists in demonstrating the practical utility, in a context of limited resources, of a study and systematic treatment strategy of refractory hypothyroidism, which has barely been published in the international literature. It is also highlighted the importance of an early specialized intervention to prevent the systemic risks associated with high doses of thyroid hormones.

Caso clínico: paciente masculino de 16 años de edad de raza negra, que presenta diarreas crónicas de 4 años de evolución, dolor abdominal periumbilical, distensión abdominal y pérdida de peso. Por esta sintomatología acude a nuestra consulta. Conclusiones: la enterotomografía axial computarizada es una herramienta valiosa a la hora de diagnosticar la enteritis por Crohn cuando no se dispone de enteroscopios. Se debe sospechar la enfermedad de Crohn en pacientes pediátricos como causa de malabsorción intestinal. La evolución del paciente fue favorable.

ABSTRACT Background: the localization of the Crohn's disease of proximal small intestine is unusual, even less frequent in pediatric age. Objective: to present the case of an adolescent with syndrome of intestinal malabsorption of not specified cause. Clinical case: 16-years-old, black, masculine patient that has for 4 years chronic diarrheas, periumbilical abdominal pain, abdominal distension and loss of weight. For these clinical elements he goes to our consultation. Conclusion: the computerized axial intestine-tomography is a valuable tool when diagnosing the enteritis for Crohn when there is not enteroscopy. Crohn's disease should be suspected in pediatric patients as cause of intestinal malabsorption. The patient's evolution was favorable.

Case report of congenital glucose-galactose malabsorption in China and literature review / 中国新生儿科杂志

Objective To study the clinical features of congenital glucose-galactose malabsorption (CGGM),and to improve the understanding of CGGM.Method Clinical manifestations and treatment process of one patient with CGGM in our hospital were retrospectively analyzed.From 1966 to 2016 May,Chinese medical database and PUBMED were searched using Malabsorption syndrome,dehydration,hypernatremia , diarrhea , newborn , carbohydrate metabolism ,andglucose/galactose malabsorption as key words.The clinical features of CGGM reported in literatures were summarized.Result The patient in our hospital was a full-term female infant naturally delivered.The onset of the disease was on the 9th day after birth,and the clinical manifestations included severe diarrhea,severe dehydration,hypernatremia,metabolic acidosis and malnutrition.After intravenous infusion and symptomatic treatment,dehydration,hypernatremia and metabolic acidosis were corrected.However,there was no improvement of diarrhea characterized with watery and acidic stools,and neither was weight gain.Glucose loading test was negative,and fructose loading test was positive.Diarrhea was improved markedly using diagnostic carbohydrate-free formula,so CGGM was diagnosed clinically.SLC5A1 homozygous IVS7-2 A ＞ G mutation was detected which confirmed the diagnosis of CGGM.With carbohydrate-free formula feeding,the body weight of the infant was increased.Followed up for 2 months now,her body length and body weight were at P25 and P22 on growth curve respectively,and no obvious neurological sequela was observed.Our literature review revealed 7 reports including 48 cases of CGGM children.Literature review showed that:most children with CGGM (79.2％) had the onset within 7 days of life;main clinical features included diarrhea (100％),dehydration (100％),and malnutrition (54.2％);22.9％ of patients with carbohydrate-free formula and 27.1％ with fructose matrix formula were fed well;no death was detected,77.1％ had normal weight gain,and 91.7％ had normal development of the nervous system.Conclusion CGGM is rare.The symptoms include severe watery and acidic stools with onset during neonatal period.CGGM is associated with severe complications such as hypertonic dehydration and hypernatremia.The diagnosis is established based upon typical clinical manifestations,sugar loading test and SLC5A1 gene detection.Carbohydrate-free formula feeding is effective.

A case of celiac disease with neurologic manifestations misdiagnosed as amyotrophic lateral sclerosis

Celiac disease (CD) is an immune-mediated enteropathy and is a rare disease in Asia, including in Korea. However, the ingestion of wheat products, which can act as a precipitating factor of CD, has increased rapidly. CD is a common cause of malabsorption, but many patients can present with various atypical manifestations as first presented symptoms, including anemia, osteopenia, infertility, and neurological symptoms. Thus, making a diagnosis is challenging. We report a case of CD that mimicked amyotrophic lateral sclerosis (ALS). The patient was a sexagenary man with a history of progressive motor weakness for 2 years. He was highly suspected as having ALS. During evaluation of his neurological symptoms, esophagogastroduodenoscopy (EGD) was performed because he had experienced loose stools and weight loss for the previous 7 months. On EGD, the duodenal mucosa appeared smooth. A biopsy revealed severe lymphoplasma cell infiltration with flattened villi. His serum endomysial antibody (immunoglobulin A) titer was 1:160 (reference, <1:40). Finally, he was diagnosed as having CD, and a gluten-free diet was immediately begun. At a 4-month follow-up, his weight and the quality of his stool had improved gradually, and the neurological manifestations had not progressed.

Enfermedad celíaca: revisión / Update on celiac disease

The prevalence of Celiac disease in the general population is approximately 1% and remains undiagnosed in a significant proportion of individuals. Its clinical presentation includes the classical malabsorption syndrome, unspecific and extra-intestinal manifestations, and silent celiac disease. The serologic diagnosis has an elevated sensitivity and specificity and, at least in adult population, it must be confirmed by biopsy in every case. Diagnosis in subjects already on gluten free diet includes HLA typing and gluten challenge with posterior serologic and histologic evaluation. The core of the treatment is the gluten free diet, which must be supervised by an expert nutritionist. Monitoring must be performed with serology beginning at 3-6 months, and with histology two years after the diagnosis, unless the clinical response is poor. Poor disease control is associated with complications such as lymphoma and small bowel adenocarcinoma. In the future, it is likely that new pharmacologic therapies will be available for the management of celiac disease.

The 453rd case:diarrhea, weight loss and diabetes mellitus / 中华内科杂志

Chronic diarrhea is a common complaint in gastroentology department,which is classified into a variety of types.While as eosinophilic gastroenteritis is a rare cause.A 50-year-old male patient was admitted with a 2-year history of diarrhea worsened for 10 months.Fasting could alleviate the diarrhea.Laboratory findings demonstrated anemia,low vitamins and minerals,fat malabsorption and abnormal D-xylose absorption test,delayed gastric emptying.According to the endoscopic biopsy of gastrointestinal mucosa,the diagnosis of eosinophilic gastroenteritis was made.Diabetic neuropathy may aggravate the symptom.The diarrhea resolved after the administration of steroids.

Eosinophilic gastroenteritis which leads to mal-absorption and anemia associated with food allergies

Eosinophilic gastroenteritis (EG) is a rare disease characterized by massive eosinophilic infiltration of gastrointestinal tissue, peripheral eosinophilia, and nonspecific gastrointestinal symptoms. The mucosal type of EG commonly presented with malabsorption and anemia. However, the role of food allergy as a stimulus to EG has not yet been clearly defined. A 27-year-old man was referred to the Emergency Department with dyspepsia and leg swelling. The initial laboratory test should as follows: hemoglobin level, 6.4 g/dL; white blood cell count, 7,400/microL with 24.4% of eosinophil fraction; serum total protein, 3.9 g/dL; albumin level, 2.8 g/dL. Gastric endoscopy ruled out gastrointestinal bleeding showed multiple nodular raised lesions on the gastric antrum, which revealed increased eosinophilic infiltration (above 100/high power field). He had experienced nausea whenever eating beef, porks or fish. High serum specific IgE levels to offending foods (beef, 0.82 kU/L; pork, 0.83 kU/L; egg white, 0.40 kU/L; egg yolk, 0.54 kU/L; milk, 0.81 kU/L) were noted. He was instructed strictly to avoid food allergens with oral prednisolone therapy. Approximately 6 months after offending food restriction, the eosinophil count fell down to 400/microL, the hemoglobin level was returned to 11.5 g/dL and the serum albumin level was increased to 4.1 g/dL. We report a case of EG caused by multiple food allergy which leads to malabsorption and iron-deficiency anemia.

Small bowel diverticulosis in patient with early gastric cancer

Jejunal and ileal diverticula are rare in adults. Duodenal diverticula are five times more prevalent than jejunoileal diverticula. Most patients are asymptomatic. However, chronic symptoms including intermittent abdominal pain, flatulence, diarrhea and constipation are seen in 10%-30% of patients. Gastric cancer is the second most common cancer in South Korea and here we report a case of early gastric cancer with multiple duodenal and jejunal diverticula. A 67-year-old woman was admitted to Konkuk University Medical Center with chronic diarrhea and weight loss of 19 kg over 2 months. Following gastroduodenoscopy, we identified adenocarcinoma of the lower body of the stomach. On abdominopelvic computed tomography, diverticula of duodenum and jejunum were found. Patient underwent distal gastrectomy and gastroduodenostomy with lymphadenectomy. She was discharged on the tenth postoperative day without complications.

Whipple's disease: rare disorder and late diagnosis / Doença de Whipple: patologia rara e de diagnóstico tardio

Whipple's disease is a rare systemic infectious disorder caused by the bacterium Tropheryma whipplei. We report the case of a 61-year-old male patient who presented to emergency room complaining of asthenia, arthralgia, anorexia, articular complaints intermittent diarrhea, and a 10-kg weight loss in one year. Laboratory tests showed the following results: Hb = 7.5 g/dL, albumin = 2.5 mg/dL, weight = 50.3 kg (BMI 17.4 kg/m²). Upper gastrointestinal endoscopy revealed areas of focal enanthema in the duodenum. An endoscopic biopsy was suggestive of Whipple's disease. Diagnosis was confirmed based on a positive serum polymerase chain reaction. Treatment was initiated with intravenous ceftriaxone followed by oral trimethoprim-sulfamethoxazole. After one year of treatment, the patient was asymptomatic, with Hb = 13.5 g/dL, serum albumin = 5.3 mg/dL, and weight = 70 kg (BMI 24.2 kg/m²). Whipple's disease should be considered a differential diagnosis in patients with prolonged constitutional and/or gastrointestinal symptoms. Appropriate antibiotic treatment improves the quality of life of patients.

Doença de Whipple é uma rara infecção sistêmica causada pelo Tropheryma whipplei. Caracteriza-se por fase prolongada de sintomas inespecíficos, levando longo período até o seu diagnóstico. Sem tratamento, pode ser grave e fatal, mas com antibioticoterapia tem ótima resposta clínica e laboratorial. Relatamos o caso de paciente masculino, 61 anos, internado por astenia, anorexia, diarréia intermitente e perda de 10 kg em um ano. Apresentava-se com hemoglobina (Hb) 7,5 g/dL, albumina de 2,5 mg/dL, peso 50,3 kg (IMC 17,4). Endoscopia digestiva alta com áreas de enantema focal da mucosa duodenal e biópsia compatível com doença de Whipple. O diagnóstico foi confirmado com PCR sérica positiva, sendo instituído tratamento com ceftriaxone seguido de sulfametoxazol-trimetropim. Após um ano de tratamento, encontrava-se assintomático, com Hb 13,5 g/dL, albumina sérica de 5,3 mg/dL e peso de 70 kg. Doença de Whipple deve fazer parte da lista de diagnósticos diferenciais em pacientes com sintomas constitucionais e/ou com queixas gastrointestinais com evolução prolongada. O tratamento antibiótico pode curar a infecção, recuperando a qualidade de vida do paciente.

Chronic Non-granulomatous Ulcerative Jejunoileitis Assessed by Wireless Capsule Endoscopy / 대한소화기학회지

Chronic non-granulomatous jejunoileitis is a rare disease characterized by malabsorption, abdominal pain, and diarrhea that causes shallow ulcers in the small bowel. The etiology of chronic non-granulomatous jejunolieitis remains unknown. A 69-year-old man complained of abdominal pain and lower extremity edema. A 99m-Tc albumin scan showed increased radioactivity at the left upper quadrant, suggesting protein-losing enteropathy. A small bowel follow-through did not disclose any lesions. Wireless capsule endoscopy revealed several small bowel ulcers and strictures. A jejunoileal segmentectomy with end-to-end anastomosis was performed, and the histologic examination revealed non-granulomatous ulcers with focal villous atrophy. Ruling out all other possible diagnoses, we diagnosed our patient with chronic non-granulomatous ulcerative jejunoileitis. Postoperatively, the patient's abdominal pain and lower extremity edema improved, and the serum albumin normalized. This is the first case of chronic non-granulomatous ulcerative jejunoileitis localized by wireless capsule endoscopy and treated successfully with segment resection.

A Case of Primary Intestinal T-Cell Lymphoma Involving Entire Gastrointestinal Tract: Esophagus to Rectum

Primary intestinal T-cell lymphoma is a rare disease entity, which is approximately 10% to 25% of intestinal lymphomas, and most of the lymphomas occur in the small intestine. We report here a case of a 56-year-old woman who has been suffering from chronic diarrhea and weight loss for 6 months. Abdominal CT scan and small bowel series showed diffuse wall thickening of the small bowel. Gastroscopic examination showed diffuse erythematous lesions on the esophagus and small gastric ulcerations on the antrum of the stomach, and colonoscopic examination also showed multiple punched-out ulcerations and erosions on the entire colon, including the sigmoid colon to the terminal ileum. Diffuse infiltration of CD 3 positive lymphoma cells was found on biopsy. The patient was diagnosed as primary intestinal T-cell lymphoma with diffuse involvement of the entire gastrointestinal tracts from the esophagus to the rectum. Although the patient received systemic combination chemotherapy and achieved partial response initially, the lymphoma relapsed repeatedly.
