RESUMEN
BACKGROUND & AIMS: Patients receiving oncological esophagectomy or gastrectomy are known to be at high risk for vitamin and micronutrient deficiency before, during and after surgery. However, there are no clear guidelines for these cancer patients regarding postoperative vitamin supplementation. METHODS: We conducted a metanalysis consisting of 10 studies regarding vitamin and micronutrient deficiencies after oncological gastric or esophageal resection. 5 databases were searched. RESULTS: Data was sufficient regarding Vitamins B12 and 25-OH D3 as well as calcium. We were able to show deficiencies in 25-OH Vitamin D3 levels (p < 0.001) and lower levels of Vitamin B12 and calcium (bit p < 0.001) when compared to the healthy population. CONCLUSIONS: Patients from these groups are at risk for vitamin deficiencies. A guideline on postoperative supplementation is needed.

BACKGROUND: The RIDART I study found a 13.6% prevalence of anemia in Italian patients with inflammatory bowel disease (IBD); most cases were due to iron-deficiency anemia (IDA). AIMS: To evaluate changes in hemoglobin concentration during a 24-week follow-up of anemic patients with IBD. METHODS: Follow-up laboratory and clinical data were obtained from RIDART I study patients with anemia. Factors affecting hemoglobin concentration, the impact of anemia on fatigue and quality of life (QoL), and its relationship with treatment, disease activity and disease complications were investigated. RESULTS: Hemoglobin was 108 g/L at baseline, increased to 121 g/L at follow-up week 12 (p < 0.001) and then stabilized until week 24, but most patients remained anemic, with IDA, throughout the study. Hemoglobin improvement was greater in patients receiving either oral or parenteral iron supplementation. Following hemoglobin normalization, anemia relapse rate during follow-up was 30%. Oral iron did not cause disease reactivation. Lower follow-up hemoglobin was associated with a higher probability of having active disease, clinical complications, increased fatigue and reduced QoL. CONCLUSIONS: In anemic patients with IBD, anemia represents a long-lasting problem, in most cases persisting for up to 24 weeks, with high relapse rate and a negative impact on fatigue and QoL.

BACKGROUND: Nonunion of femoral shaft fractures in children is rare, and there is no clear treatment protocol. In this case report, a pediatric femoral shaft fracture that developed in nonunion due to vitamin deficiency after osteosynthesis, which was successfully treated with vitamin augmentation and replacement with a rigid antegrade intramedullary nail, is described. CASE PRESENTATION: The patient is an 11-year-old Japanese girl. She injured her right femoral shaft fracture when she hit a wall after kickboarding down a hill and underwent osteosynthesis with a titanium elastic nail. Six months postoperatively, she developed nonunion, was found to be deficient in vitamins D and K, and was started on vitamin supplementation. She underwent replacement with a rigid antegrade intramedullary nail at 7 months postoperatively, and bone union was achieved 3 months after reoperation. CONCLUSION: When delayed union of a fracture is observed postoperatively, even in children without underlying disease, the cause of the problem must be investigated and treated promptly.

Vitamin C deficiency, otherwise known as scurvy, is a rare diagnosis among populations with adequate nutritional resources. We present a 37-year-old female patient with bilateral lower extremity edema, episodic anasarca, petechiae, and easy bruising who was diagnosed with scurvy. Given the clinical presentation, a broad differential was investigated with no findings suggestive of hematologic or cardiovascular pathology. Initial laboratory studies were unremarkable. Progression of cutaneous symptoms and subsequent laboratory findings demonstrating low vitamin C levels supported a diagnosis of scurvy. Classical symptoms of scurvy include mucocutaneous petechiae, poor wound healing, ecchymosis, hyperkeratosis, corkscrew hair, gingival swelling, and bleeding gums. Following standard enteral supplementation of vitamin C, repeat vitamin C levels failed to adequately respond with the patient remaining to be symptomatic. Given a lack of insufficient nutritional intake or known systemic illness, gastrointestinal malabsorptive etiology was suspected. Though rare in the United States, scurvy should be considered in patients with manifestations of a bleeding disorder. A gastrointestinal workup may be indicated if other nutritional deficiencies are identified, or a source of inadequate intake cannot be established.
RESUMEN
Background: Vitamin D is best known as a key regulator of bone metabolism and calcium and phosphate homeostasis. This study aimed to assess the effect of different factors on the five-year changes in serum vitamin D concentration among older adults. Methods: This cohort study was conducted on adults aged ≥60 years living in Amirkola, in the North of Iran, from 2012 to 2017. Serum 25-hydroxyvitamin D (25-OH vitamin D) concentrations of <20, 20-29.99, and ≥30 ng/mL, respectively, were used to designate vitamin D deficiency, insufficiency, and sufficiency. Any variation between the second and baseline values of the 25-OH vitamin D concentration was reported as a five-year difference. Data were analyzed using SPSS version 17.0, and Chi square, t test, one-way ANOVA, and Tukey HSD post hoc tests were employed. P values less than 0.05 were considered statistically significant. Results: The mean serum concentration of 25-OH vitamin D at baseline and follow-up examination in 1011 individuals was 34.68±33.18 and 23.88±14.91, respectively (P<0.001). Following a five-year follow-up, vitamin D deficiency, insufficiency, and sufficiency were found in 452 (44.7%), 334 (33.0%), and 225 (22.3%) cases, respectively. The reduction in serum 25-OH vitamin D concentration after five years was significantly influenced by the administration of vitamin D (P=0.013) and calcium (P=0.007) supplements, serum profile of parathyroid hormone (PTH) (P=0.010), calcium (P=0.021), and phosphorous (P=0.021). However, age, sex, body mass index, metabolic syndrome, and physical activity had no significant impact (P>0.05). Conclusion: Regardless of age, sex, body mass index, metabolic syndrome, or physical activity, the mean serum concentration of vitamin D decreased over a five-year follow-up.

Riboflavin transporter deficiency (RTD) is a rare genetic disorder that can have detrimental effects on the nervous system, causing progressive neurodegeneration. Here, we report the second case of RTD in Saudi Arabia. An 18-month-old boy presented to the otolaryngology clinic with six weeks history of progressive noisy breathing associated with drooling, choking, and difficulty in swallowing. Progressive regression of the child's motor and communicative abilities was reported as well. Upon examination, the child had biphasic stridor, chest retractions, bilateral facial palsy, and hypotonia. The presence of an aerodigestive foreign body or congenital anomalies was excluded using bronchoscopy and esophagoscopy. Empirical high-dose riboflavin replacement therapy was initiated upon anticipation of diagnosis. Whole exome sequencing revealed a SLC52A3 gene mutation, which confirmed the diagnosis of RTD. After a period of intensive care unit (ICU) admission with endotracheal intubation, the child's general condition improved, and he was weaned off of respiratory support. Tracheostomy was avoided in this patient, as he responded to riboflavin replacement therapy. During the disease course, an audiological assessment revealed severe bilateral sensorineural hearing loss. He was discharged home on gastrostomy feeding owing to the risk of frequent aspiration, and he was regularly followed up by the swallowing team. The early initiation of high-dose riboflavin replacement appears to be of great value. The benefits of cochlear implants in RTD have been reported, but not fully established. This case report will increase awareness in the otolaryngology community about patients with this rare disease who might initially present to the clinic with an otolaryngology-related complaint.
RESUMEN
BACKGROUND: Anemia is a common extraintestinal manifestation of inflammatory bowel disease (IBD), with a 6% to 74% prevalence and a negative impact on patient survival and quality of life, although the prevalence is apparently declining due to improved disease treatment. We aimed to investigate the prevalence, pathogenesis, and clinical correlates of anemia in Italian patients with IBD. METHODS: A multicenter, prospective, observational study, involving 28 Italian gastroenterology centers, was conducted to investigate the epidemiology and consequences of IBD-associated anemia. Clinical and laboratory data of anemic patients were obtained at study enrolment. RESULTS: Anemia was diagnosed in 737 of 5416 adult IBD outpatients (prevalence 13.6%); females were more commonly affected than males (odds ratio, 1.5; 95% confidence interval [CI], 1.2-1.7) and had more severe anemia. In the majority of cases, anemia was due to iron deficiency (62.5% of cases; 95% CI, 58.3%-66.6%), either isolated or in association with inflammation and/or vitamin deficiencies; anemia of inflammation accounted for only 8.3% of cases. More severe anemia was associated with increasing fatigue and worse quality of life. Only 68.9% of anemic patients with iron deficiency (95% CI, 63.4%-73.8%) and 34.6% of those with vitamin deficiencies (95% CI, 26.2%-44.2%) were properly treated with supplementation therapy. CONCLUSIONS: In Italy, the prevalence of IBD-associated anemia is lower than previously reported. Anemia of IBD is most commonly due to iron deficiency and contributes to fatigue and poor quality of life, but remains untreated in a large proportion of patients with iron and/or vitamin deficiencies. This study is registered at clinicaltrials.gov as NCT02872376.
The prevalence of inflammatory bowel diseaseassociated anemia is 13.6%. The prevalence is higher among females younger than 50. Anemia is usually due to iron deficiency and adversely affects fatigue and quality of life. Many patients with iron or vitamin deficiency (31% and 65%, respectively) remain untreated.

Background An appropriate diet is critical for the growth and development of infants, especially in the first two years of life. Despite considerable efforts made by government and local authorities to raise awareness, mothers still lack basic knowledge of weaning practices; as a result, infants face a growing number of health problems in their later years of life. This research aims to investigate the association between malnutrition and knowledge of different weaning practices among mothers and to study the factors influencing it. Methodology The current study was a cross-sectional study conducted at Mayo Hospital, Services Hospital, and Jinnah Hospital, Lahore, Pakistan between November 2019 and May 2020. A total of 200 infants of both genders aged between one and 12 months were included in the study. Knowledge and practices of complementary feeding by the mothers were assessed using a close-ended, pre-tested questionnaire. Results Mothers of 200 infants were interviewed and it was found that 79.5% of the infants were being breastfed while 24% never received breast milk. Among those who never received breast milk were given liquids (25%) and semi-solid foods (64.5%). Of the mothers, 8% started weaning at an early age (less than six months old) while the remaining started weaning at the age of six months or later and reported that their infants were either underweight or had reduced heights for that age. Based on the medical reports obtained from the hospital after getting parental consent, it was also found that the infants had distinct signs of deficiency of vitamins A and D, iron, and folate. Conclusions The majority of infants were breastfed, and, in most cases, weaning started at an age of less than six months. Most of the infants were fed semi-solid food as their first complementary food. Two-thirds of the infants were underweight for that age, and one-fifth had reduced heights. Based on deficiency statistics, mothers should be encouraged to start weaning at six months to have minimized malnourishment instances in infants.
RESUMEN
Patients undergoing stem cell transplantation (SCT) are at high risk of malnutrition during the acute post-transplantation period. This systematic review aimed to collate and analyse the evidence for vitamin requirements post-SCT. A systematic search of five databases was conducted to include studies published until March 2021. The review utilised the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) framework. Inclusion criteria consisted of adults undergoing SCT who received vitamin supplementation or had their vitamin levels monitored up to 100 days post-SCT. Studies with paediatric patients or those that looked at vitamin derivates such as folinic acid were excluded. Main outcomes included vitamin deficiency and relevant clinical outcomes. Eleven studies (n = 11) were eligible for inclusion with five rated as neutral quality and six as positive quality. Five studies focused on allogenic SCT, two on autologous SCT and the remaining included a mix of both. Eight studies monitored vitamins levels post-SCT, and seven studies provided vitamin supplementation. Three studies (one provided supplementation) found a high prevalence of vitamin D deficiency (23-60%) prior to SCT. Findings indicate an unclear association between vitamin deficiency and post-SCT complications including acute graft-versus-host-disease, oral mucositis, and mortality. The GRADE certainty of evidence across these outcomes was low or very low. It is unclear if supplementation is needed during SCT, though assessing vitamin D levels prior to transplant should be considered. Further large observational studies or randomised control trials are required to establish vitamin requirements and guide supplementation protocols during SCT.

BACKGROUND: Vitamin B6 (pyridoxine) is an important cofactor in the process by which glutamic acid decarboxylase (GAD) converts the excitatory, pro-epileptogenic neurotransmitter, glutamate, into the inhibitory, anti-epileptogenic neurotransmitter, gamma-aminobutyric acid (GABA). This concept has been established in infants with pyridoxine-dependent epilepsy as well as adult patients with other epilepsy subtypes who presented with medication-resistant status epilepticus, with both patient groups experiencing cessation of seizure activity following pyridoxine administration. Given our knowledge of the role of vitamin B6 in the conversion of glutamate to GABA, its effect on seizure control in infants with specific epilepsy subtypes, reports of adult-onset seizures associated with vitamin B6 deficiency, and vitamin B6's role in terminating status epilepticus in adult patients with other types of epilepsy, we suspect that low vitamin B6 levels in adult epilepsy patients may correlate with poor seizure control across all epilepsy subtypes. This study seeks to determine whether there is a relationship between pyridoxine levels and the level of seizure control in adults with epilepsy, regardless of their seizure type. METHODS: After obtaining institutional review board approval, we prospectively enrolled 32 patients (age range: 25-57 years) with epilepsy who presented to our clinic. Patients who did not meet the study criteria or who were diagnosed with psychogenic non-epileptic seizures (PNES) were excluded from the study (n = 2). Patients were classified as well-controlled (WC) or poorly controlled (PC) based on the absence or presence of a seizure within the last three months, respectively. After classification as WC or PC, pyridoxine serum levels and anti-seizure medication (ASM) levels were drawn in that clinic visit, following patient consent. All patients were contacted regarding pyridoxine and serum ASM levels, and patients that were found to be deficient in pyridoxine were treated with appropriate supplementation. At the end of the recruitment period, we performed analyses to determine if there was a statistically significant relationship between PC status and serum pyridoxine levels. RESULTS: Of 32 patients, two patients were diagnosed with psychogenic non-epileptic events and were subsequently excluded. Of 30 patients, 10 had PC epilepsy. Median (interquartile range) serum B6 levels were 35.8 (26.8-54.2) in patients with WC epilepsy and 17.5 (10.1-41.3) in patients with PC epilepsy (P = 0.11). In the PC group, 6/10 (60%) of the patients demonstrated low serum pyridoxine compared to 3/20 (15%) in the WC group (P = 0.03). CONCLUSION: There was a statistically significant relationship between serum pyridoxine levels and seizure control. If appropriate, pyridoxine supplementation should be considered, especially in critically ill adult patients with refractory or PC seizures despite good adherence to ASMs.
RESUMEN
An 8-month-old, exclusively breastfed girl presented with a five-month history of vomiting with subsequent failure to thrive and lethargy. Family history was notable for the maternal history of gastroschisis. Mother had no dietary restrictions and had successfully breastfed multiple children for >12 months without issue. Initial evaluation was notable for macrocytic anemia. Subsequent serum B12 levels were undetectable. Upon further questioning, the mother had significant bowel resection as an infant due to complications of gastroschisis. Maternal serum B12 levels were also undetectable. The infant's symptoms resolved with supplementation.
RESUMEN
INTRODUCTION AND IMPORTANCE: Short bowel syndrome is characterized by maldigestion and malabsorption resulting in deficiencies of multiple nutrients including vitamins and minerals. Most subjects required parental elimination for survival. GLP-2 RA Teduglutide was recently approved for treatment of short bowel syndrome especially for those requiring parenteral support. Our intent in reporting this subject is to demonstrate the utility of Teduglutide in improving multiple metabolic indices in presence of short bowel syndrome. CASE PRESENTATION AND CLINICAL DISCUSSION: 66-year-old Caucasian female presented with a history of short bowel syndrome and associated vitamin deficiencies, hypothyroidism requiring large dose (300 µg) of levothyroxine, diarrhea and liver cirrhosis. Upon starting teduglutide the subject saw improvement in her symptoms. Moreover, daily dose of Levothyroxine required a gradual decrease to maintain desirable serum concentrations of Free T4, Free T3 and TSH. Serum levels of several vitamins attained greater than therapeutic concentrations requiring dosage reductions. Also notable was the improvement in her liver function tests, remission from ascites and episodes of hepatic encephalopathy and regeneration of liver nodules. CONCLUSION: Following administration of GLP2 therapy, an adult subject with short bowel syndrome with concurrent hypothyroidism and multiple vitamin deficiencies, demonstrated a marked improvement in her metabolic parameters resulting in reduction in daily medication doses along with improvement in manifestations of liver cirrhosis.
RESUMEN

Complete deficiency of apolipoprotein (apo) B-containing lipoproteins can result from both abetalipoproteinemia (ABL) and homozygous hypobetalipoproteinemia (HoHBL), caused by bi-allelic loss-of-function variants in the MTTP and APOB genes encoding microsomal triglyceride transfer protein and apolipoprotein (apo) B, respectively. Both conditions are associated with failure to assemble and secrete apo B-containing lipoproteins from intestine and liver, resulting in absence of chylomicrons, very low-density lipoproteins and remnants, and low-density lipoproteins. Because absorption and transport of fat soluble vitamins requires intact production of apo B-containing lipoproteins, untreated patients develop fat soluble vitamin deficiencies, with associated clinical features including atypical retinitis pigmentosa, osteopenia, neuromyopathy and coagulopathy. Other features include acanthocytosis on the peripheral blood film, fat malabsorption and hepatosteatosis. We describe two patients with ABL and one with HoHBL who have each been on high dose oral fat soluble vitamin replacement under the care of the same physician for more than four decades. Each patient has remained clinically stable. A recent liver biopsy from an ABL patient showed mild macrovesicular steatosis, patchy microvesicular steatosis and mild fibrosis. These observations add to our understanding of the long term trajectory of ABL and HoHBL, and emphasize the importance of compliance to treatment and follow up.

OBJECTIVE: Determine vitamin B12 threshold levels below which additional testing of methylmalonic acid (MMA) and/or homocysteine (Hcy) is useful to diagnose metabolic vitamin B12 deficiency in patients with polyneuropathy, and how vitamin B12, MMA and Hcy levels relate to the effect of supplementation therapy. METHODS: In a retrospective cohort study of 331 patients with polyneuropathy, vitamin B12, MMA and Hcy were measured. Linear regression models with vitamin B12 as dependent and Hcy or MMA as covariate were compared, to assess which was best related to vitamin B12. Threshold vitamin B12 levels for metabolic deficiency (defined as elevatede metabolites) were determined using logistic regression with elevated metabolites as dependent and vitamin B12 as covariate. A structured interview was conducted in 42 patients to evaluate response to vitamin B12 supplementation. RESULTS: MMA was best related to vitamin B12. Using elevated MMA for metabolic deficiency, we found 90% sensitivity at a vitamin B12 threshold level <264 pmol/L (358 pg/mL) and 95% sensitivity at <304 pmol/L (412 pg/mL). Improvement after supplementation was reported by 19% patients and stabilization by 24%. 88% of patients with improvement and 90% with stabilization either had absolute deficiency (Vitamin B12 < 148 pmol/L) or metabolic deficiency (elevated MMA and vitamin B12 ≥ 148 pmol/L). There were no additional patients with improvement or stabilization with isolated elevated Hcy. CONCLUSION: Testing of MMA has additional value in identifying patients with clinically relevant metabolic deficiency when vitamin B12 is below 304 pmol/L (412 pg/mL). Supplementation can be effective in patients with absolute and metabolic deficiency.

Vitamin C (ascorbic acid) is an essential water-soluble antioxidant, and deficiency (ie, plasma level <11 µmol/L) can result in scurvy. People at the highest risk for vitamin C deficiency (ie, scurvy) are those with inadequate intake, such as patients with alcohol abuse disorder, malnutrition, psychiatric disorders, restrictive eating habits, and food insecurity, as well as those with malabsorptive syndromes. We present a case of a 26-year-old woman with Crohn's colitis, myasthenia gravis, and juvenile rheumatoid arthritis who presented with frequent bruising, epistaxis, and excessive bleeding from small cuts and who was found to be deficient in vitamin C. Plasma levels initially normalized with oral vitamin C supplementation, but bleeding symptoms eventually returned despite high-dose oral supplementation with 2000 mg daily. She ultimately required routine intravenous supplementation in the home setting for the normalization of levels and the resolution of symptoms. Case reports of vitamin C deficiency typically involve patients with an inadequate intake of vitamin C-containing foods or inadequate absorption. In contrast, our patient reported a regular intake of vitamin C-containing foods, in addition to oral supplementation, but continued to have difficulty maintaining normal vitamin C levels. Scurvy should be considered for any patient with symptoms of bleeding, petechiae, or ecchymosis and, although it can typically be treated with oral vitamin C, intravenous repletion may be necessary in some cases.

By virtue of their regulatory role in various metabolic and biosynthetic pathways for energy status and cellular integrity, both hydro-soluble and lipo-soluble vitamins are considered to be involved in maintaining cardiovascular function in health and disease. Deficiency of some vitamins such as vitamin A, B6, folic acid, C, D, and E has been shown to be associated with cardiovascular abnormalities whereas supplementation with these vitamins has been claimed to reduce cardiovascular risk for hypertension, atherosclerosis, myocardial ischemia, arrhythmias, and heart failure. However, the data from several experimental and clinical studies for the pathogenesis of cardiovascular disease due to vitamin deficiency as well as therapy due to different vitamins are conflicting. In this article, we have attempted to review the existing literature on the role of different vitamins in cardiovascular disease with respect to their deficiency and supplementation in addition to examining some issues regarding their involvement in heart disease. Although both epidemiological and observational studies have shown some merit in the use of different antioxidant vitamins for the treatment of cardiovascular disorders, the results are not conclusive. Furthermore, in view of the complexities in the mechanisms of different cardiovascular disorders, no apparent involvement of any particular vitamin was seen in any specific cardiovascular disease. On the other hand, we have reviewed the evidence that deficiency of vitamin B6 promoted KCl-induced Ca2+ entry and reduced ATP-induced Ca2+-entry in cardiomyocytes in addition to decreasing sarcolemmal (SL) ATP binding. The active metabolite of vitamin B6, pyridoxal 5'-phosphate, attenuated arrhythmias due to myocardial infarction (MI) as well as cardiac dysfunction and defects in the sarcoplasmic reticulum (SR) Ca2+-transport in the ischemic-reperfused hearts. These observations indicate that both deficiency of some vitamins as well as pretreatments with different vitamins showing antioxidant activity affect cardiac function, metabolism and cation transport, and support the view that antioxidant vitamins or their metabolites may be involved in the prevention rather than the therapy of cardiovascular disease.
RESUMEN
BACKGROUND: Chylomicron retention disease (Anderson disease) is a result for variant of the SAR1B gene. It is a rare autosomal recessive hereditary disorder with most incidence in infant. It is characterized by lipid malabsorption syndrome with fatty, chronic diarrhea, and growth retardation. CASE PRESENTATION: We report a case of a 19-month Syrian boy who presented with vomiting, growth failure, and chronic, fatty diarrhea. Upper gastrointestinal endoscopy showed whitish appearing duodenal mucosa and small intestinal biopsies revealed steatosis of enterocytes. Genetic testing confirmed chylomicron retention disease with the first description of variant located in the fourth helix of sar1b protein. The patient is treated with nutritional supplements and fat-soluble vitamin supplementation resulting in significant improvement. CONCLUSION: Early endoscopy is recommended in infants with persistent vomiting and failure to thrive due to high suspicion for a disorder of hypocholesterolemia. Early diagnosis and treatment are essential to avoid serious clinical complications, especially neurological impairment.

We reviewed the literature to evaluate potential associations between vitamins, nutrients, nutritional status or nutritional interventions and presence or healing of foot ulceration in diabetes. Embase, Medline, PubMed, and the Cochrane Library were searched for studies published prior to September 2020. We assessed eligible studies for the association between nutritional status or interventions and foot ulcers. Fifteen studies met the inclusion criteria and were included in this review. Overall, there is a correlation between poor nutritional status and the presence of foot ulceration or a delay in healing. However, there is not enough data to reach conclusions about whether the relationships are causal or only association. Further research is required to test whether any forms of nutritional supplementation improve foot ulcer healing.

INTRODUCTION: Fetal intracranial hemorrhage (ICH) is a rare but serious prenatal diagnosis. Predisposing factors include maternal trauma and fetal coagulation dysfunction. Maternal vitamin K deficiency has been described as an etiology. We present a case of maternal vitamin K deficiency associated with fetal ICH after percutaneous biliary drain (PBD) placement in a complicated cholecystectomy with injury to the common bile duct. CASE PRESENTATION: A 21-year-old woman, G2P1, presented at 23 weeks and 3 days of gestation with epigastric pain, nausea and vomiting. Right upper quadrant ultrasound diagnosed cholelithiasis. The patient was managed conservatively and discharged. She returned four days later, at 24 weeks of gestation, with worsening symptoms and ultrasound showing acute cholecystitis. She underwent laparoscopic cholecystectomy. Increasing bilirubin and imaging showed a transected biliary duct that required percutaneous biliary drain (PBD) placement. The patient was discharged and followed up at a high-risk obstetric clinic. Prenatal ultrasound showed bilateral ventriculomegaly with features of ICH. Maternal vitamin K deficiency was confirmed with PIVKA-II testing. The patient received vitamin K supplementation with normalization of the coagulopathy. Delivery occurred at 36 weeks of gestation via cesarean delivery after preterm premature rupture of membranes for fetal macrocrania. The neonate was discharged to a hospice. DISCUSSION: Maternal and neonatal etiologies for ICH include malabsorption and coagulopathy. Maternal vitamin K deficiency should be considered when coagulopathy is present. This case highlights that maternal vitamin K deficiency due to biliary diversion and malabsorption increases the risk of fetal ICH, which impacts pregnancy and neonatal outcomes.
