Scurvy and vitamin C deficiency in an Australian tertiary children's hospital.

AIM: We aimed to investigate the frequency of vitamin C deficiency scurvy in the Australian paediatric context, describe cohorts at risk, and identify factors associated with development of symptoms in children with vitamin C deficiency. We also aimed to propose a management guideline for children with features of scurvy. METHOD: A retrospective study was done at a tertiary paediatric hospital in Australia over a three-year period, from August 2019 to July 2022. Children from birth to 18 years old, whose vitamin C levels were low (<23 µmol/L), were included. Data extracted from hospital medical records included demographics, weight, co-morbidities, eating disorder diagnoses, clinical features, investigations and treatment. Descriptive statistics and risk statistics were performed. RESULTS: In a cohort of 887 patients who had their vitamin C levels checked, we identified 272 (31%) who had a vitamin C level <23 µmol/L. Of these, 13 (5%) were symptomatic of vitamin C deficiency and 19 (7%) may have been symptomatic. In patients with vitamin C deficiency, 248 (91%) had comorbidities, neurodevelopmental disorders being most common, and 176 (65%) had restricted eating. When the asymptomatic and symptomatic groups were compared, in the symptomatic group, there was a significantly lower vitamin C level and disordered eating related to autism spectrum disorders was more common. CONCLUSION: In order to avoid delayed diagnoses and unnecessary investigations, clinicians should be familiar with symptoms of scurvy and perform a dietary assessment, vitamin C assay, and commence empiric vitamin C supplementation where appropriate.

Characteristic Skin Eruptions with a Distinct Histological Pattern Allow Early Diagnosis of Vitamin C Deficiency.

Introduction: Scurvy has become a rare disease in western countries with potentially high morbidity. Early diagnosis is crucial and can be challenging. Case Presentation: We present the case of a 56-year-old male patient who developed hemorrhagic diathesis after trivial impact trauma. Previously, the patient suffered from fatigue and loss of appetite. Characteristic skin eruptions and a distinct skin histology along with a decreased serum vitamin C level led to the diagnosis of scurvy. Following vitamin C supplementation, symptoms improved rapidly. Conclusion: In conclusion, vitamin C deficiency should be considered in cases with unclear hemorrhagic diathesis and a medical history of nutritional irregularities. Especially in cases of scurvy that do not yet show the full clinical spectrum of symptoms or have only moderately decreased serum vitamin C levels, thorough clinical dermatological examination and a skin biopsy are essential for early diagnosis and to prevent complications.

Role of Antioxidant Vitamins in Oral Submucous Fibrosis: A Narrative Review.

Oral submucous fibrosis (OSMF) has a high rate of malignant transformation and is an insidious chronic inflammatory disease. Though this disorder seems to be multifactorial in origin, betel quid chewing appears to be the main etiologic factor. Various treatment strategies have been attempted but none proven to cure the disorder because of its multimodal pathogenesis. Reactive oxygen species (ROS) appear to have a role in cancer formation. As OSMF is an oral premalignant disorder and found to be associated with carcinogens like areca nut and tobacco, it is believed to have some relationship with ROS. Tissue damage due to ROS along with other mechanisms may result in the complex pathophysiology of OSMF. The antioxidant system in the body helps to prevent damage caused by highly reactive ROS and helps in the repair of tissues. To study the levels of oxidative stress and antioxidant vitamins in OSMF condition, the present review was done. We carried out a thorough literature search to identify original reports and studies determining the status of oxidative stress and antioxidant vitamins in OSMF condition using several databases including Google Scholar, PubMed, and Scopus. Our review observed that the oxidative stress increased in the condition of OSMF as shown by an increase in malonaldehyde (MDA) and a decrease in antioxidant vitamins like vitamin A, vitamin C, and vitamin E. Also, after the intake of antioxidant vitamins, there was symptomatic improvement in OSMF patients. With the help of identifying oxidative stress and antioxidant status, we can assess the clinical stage of OSMF and can develop a comprehensive treatment plan.

Uncommon Scurvy Manifestation: Solitary Skin Lesion in an Alcoholic Case.

Scurvy, characterized by vitamin C deficiency, typically manifests with various symptoms, most commonly skin lesions. However, the presentation of a solitary skin lesion is considered atypical. An elderly patient with a history of heavy alcohol consumption presented with a small skin lesion that developed rapidly into a solitary open wound without any preceding trauma. Laboratory analysis revealed severe vitamin C deficiency (<5 µmol/L). The patient showed significant improvement following high-dose vitamin C replacement therapy. This case underscores the potential for scurvy to present with a solitary lower body wound devoid of typical symptoms. It highlights the importance of prompt consideration of vitamin C replacement therapy, particularly in high-risk groups such as alcoholics, by healthcare providers.

Vitamin C Deficiency Masquerading as Vasculitis in a Patient With Crohn's Disease.

This case study features a 40-year-old male with Crohn's disease (CD) who was initially misdiagnosed with vasculitis but was later shown to have scurvy owing to vitamin C deficiency. The patient's diet was nearly exclusively made up of highly processed fast food, with no fresh fruits or vegetables. A mildly sensitive, violaceous rash on his lower legs, mild gingival hemorrhage and enlargement, and muscle soreness were among his symptoms. Anemia and undetectable vitamin C levels were discovered in laboratory studies. A skin sample revealed follicular hyperkeratosis, coiled hairs, and perifollicular bleeding, eliminating the possibility of vasculitis. Scurvy was confirmed by undetectable vitamin C levels and intramuscular bleeding discovered during a muscle biopsy. After one month of vitamin C administration, the patient's skin was entirely clear. This instance emphasizes the significance of taking vitamin C insufficiency into account in patients with CD and other disorders that can cause malabsorption. Misdiagnosis might result in unneeded treatments and medical expenses. Scurvy must be diagnosed as soon as possible because it might cause gastrointestinal/intracerebral hemorrhage and death.

Vitamin C and Thiamin Deficiencies in Patients Undergoing Laparoscopic and Robotic Gastric Band Removal.

Outcomes after adjustable gastric banding (AGB) were unsatisfactory and many devices need to be removed for dysphagia. Vitamin C and thiamin deficiency are rare conditions in industrialized countries. Patients undergoing AGB removal (90% for dysphagia) from 2021 to 2023 (laparoscopic 15 and robotic 5) were tested for vitamin C and thiamin levels. Twenty patients (8 m/12 f median aged 56 (range 33.6-79.4) were included. BMI at AGB removal was 39.7 (range 24.4-50.1) kg/m2. Only 20% of patients had normal thiamin levels, 30% had low levels, 20% were deficient, and 30% were critically low. Only 25% of patients had normal vitamin C levels, 40% had low levels, 25% were deficient, and 10% were critically low. One third of patients had HbA1c levels between 5.8 and 6.4 and 22% had levels >6.5; 60% of patients had hyperlipidemia. Adjustable gastric banding patients develop concerning rates of vitamin C and thiamin deficiency, and routine testing for levels is recommended.

A Case of Scurvy Associated With Intracerebral Hemorrhage in a Patient With Alcohol Use Disorder.

Vitamin C deficiency, also known as scurvy, causes abnormalities in connective tissues and varied symptoms. We describe a patient with putaminal hemorrhage, a very rare presentation of scurvy. A 39-year-old man presented with weakness in the left arm and left leg. Right putaminal hemorrhage was initially diagnosed, and he underwent evacuation of the intracerebral hemorrhage. Scurvy was suspected when repeated physical examinations revealed a bleeding tendency and multiple untreated dental caries, missing teeth, and gingivitis. A diagnosis of scurvy was further supported by the patient's history of smoking, alcohol use disorder, poor diet, and low plasma vitamin C concentration. After receiving oral nutritional supplementation including vitamin C, the bleeding tendency quickly improved. This case highlights the importance of including scurvy in a differential diagnosis for patients with bleeding tendencies, especially those with a poor diet or unknown dietary history. Empirical administration of vitamin C is a reasonable treatment.

Severe Acute Malnutrition Presenting With Scurvy: A Case Report.

Scurvy is a disease caused by a lack of vitamin C. It is a nutritional deficiency that is associated with multiple severe conditions. Although developed countries report these cases rarely now due to advancements in food and nutritional supplements, they are still prevalent in developing countries, albeit rare, because of poor nutritional status. Due to the lower prevalence of scurvy, diagnosis is delayed in the majority of cases and sometimes missed completely, which results in serious complications and unnecessary workups. Here, we present a rare case of a four-year-old female child with severe acute malnutrition (SAM) presenting with scurvy. The initial clinical signs showed SAM. X-ray and MRI of the left femur and knee were done to further evaluate the orthopedic parameters. Clinical presentation and radiographic imaging confirmed all the signs of scurvy. The patient was started on the Formula 75 (F-75) diet to address the severe malnutrition, and steady weight gain was observed.

An Unusual Etiology of Severe Right Heart Failure Deserving of Wider Recognition.

A previously healthy 31-year-old man presented with worsening shortness of breath and a petechial rash. Echocardiography showed severe right-sided heart failure with midsystolic notching of the antegrade right ventricular outflow Doppler envelope suggesting pulmonary hypertension. An extensive work-up revealed scurvy, with a dramatic resolution of symptoms shortly after vitamin C supplementation.

Pediatric scurvy case report: a novel presentation with deep vein thrombosis secondary to large bilateral spontaneous iliac subperiosteal hematomas.

BACKGROUND: Scurvy is an uncommon disease in developed countries caused by deficiency of vitamin C. We present a case of scurvy in a 14-year-old male with autism with both novel presentation and imaging findings. This case had the novel presentation of lower limb deep vein thrombosis (DVT) secondary to compression of the external iliac vein from large bilateral iliac wing subperiosteal hematomas. Subperiosteal hematoma is a well-recognised feature of scurvy but large and bilateral pelvic subperiosteal hematoma causing DVT has not previously been described. CASE PRESENTATION: A 14 year old Caucasian male with background of autism and severe dietary restriction presented with lower limb swelling and immobility. He was diagnosed with lower limb DVT. Further investigation revealed an iron deficiency anaemia, and he was found on MRI to have large bilateral subperiosteal iliac hematomata causing compression of the iliac vessels. He improved following treatment with vitamin C replacement and follow-up imaging demonstrated resolution of the DVT and hematoma. CONCLUSION: DVT is rare in children and when diagnosed should prompt investigation as to the underlying cause. This case demonstrates an unusual cause of DVT and as an unusual presentation of paediatric scurvy.

Scurvy in a young man: a rare case report.

Scurvy, resulting from vitamin C deficiency, has nonspecific constitutional symptoms, including weakness, malaise, and fatigue. It is frequently misdiagnosed due to the lack of specific clinical manifestations. Although there are sporadic cases of scurvy currently reported in children, scurvy in young people is seldom encountered. Here, we report on a 25-year-old male patient without any underlying conditions who presented with severe pain and ecchymoses of both lower extremities. He was diagnosed with scurvy due to a long history of staying indoors and inadequate intake of fruits or vegetables.

Scurvy: old disease, new lessons.

Scurvy, the condition associated with severe vitamin C deficiency, is believed to be one of the oldest diseases in human history. It was particularly prevalent during the Age of Sail, when long sea voyages without access to fresh food resulted in an epidemic which claimed millions of lives; however, scurvy has existed across time and geography, occurring whenever and wherever diets are devoid of vitamin C. Young children, specifically, were affected by the emergence of 'infantile scurvy' in the 19th century owing to the use of heated milk and manufactured infant foods of poor nutritional quality. Scurvy continues to occur in at-risk groups. In children and youths, it is primarily observed in the context of autism spectrum disorder and feeding problems such as a limited food repertoire and high-frequency single food intake. Diagnosis may be delayed and invasive testing undertaken owing to clinicians' lack of familiarity with the disease, or the mistaken assumption that it is exclusively a disease of the past. The aetiology, clinical manifestations and treatment of scurvy are described. Its long history and current epidemiology are also reviewed, demonstrating that scurvy is very much a disease of the present. It is suggested that future efforts should focus on (i) anticipatory guidance and early nutritional intervention, informed by an understanding of scurvy's epidemiology, with the aim of preventing the disease in those at risk, and (ii) prompt recognition and treatment to minimise morbidity and healthcare costs.Abbreviations: ASD: autism spectrum disorder.

Reversible severe pulmonary hypertension and right heart failure with cardiogenic shock due to scurvy: a case report.

Background: The systemic complications of vitamin C deficiency, otherwise known as scurvy, have been well-documented in history. Few case reports have documented severe cardiopulmonary complications such as right heart failure (RHF) and pulmonary hypertension (PH). Case summary: A 25-year-old female presented to the hospital with two weeks of progressive fatigue, dyspnoea, myalgias, and arthralgias. She was admitted for symptomatic anaemia requiring transfusion. Her symptoms persisted and she developed severe PH and RHF, complicated by cardiogenic shock and multiple episodes of cardiac arrest. She was found to have severe vitamin C deficiency secondary to a severely self-restricted diet. After repletion of vitamin C, the patient had complete resolution of RHF and PH. Discussion: This case adds to the sparse literature documenting severe cardiopulmonary complications of vitamin C deficiency. We believe that this is the first adult case of scurvy causing RHF and PH leading to cardiogenic shock and episodes of cardiac arrest. There are multiple hypotheses on the pathogenesis of scurvy-associated PH and RHF, including overactivation of hypoxia-inducible transcription factors and deficiency of vitamin C's vasodilatory effect that acts through increased nitric oxide production in endothelial cells. When recognized, early vitamin C repletion may prevent severe cardiopulmonary complications of scurvy.

Association Between Vitamin Deficiencies and Ophthalmological Conditions.

Vitamin deficiencies can have adverse effects on health, including on the visual system. The ocular manifestations of a vitamin deficiency are related to the underlying biochemical function of the particular nutrient. While vitamin deficiencies are not common in developed counties, they are still prevalent in parts of the developing world and in specific, vulnerable populations. Vitamin deficiencies can cause or contribute to many ophthalmological conditions and eye diseases may even be the first presenting finding of a vitamin deficiency. As such, it is important for ophthalmologists to be aware of the ocular manifestations of vitamin deficiencies, especially given that the complications can be severe and effectively treated if identified early. This review summarizes the literature on the main vitamins known to have characteristic ocular manifestations: vitamins A, B1, B2, B9, B12, C, D, E and K. The function, epidemiology, manifestations, workup, and management of each vitamin is discussed in detail.

Risk of Hypovitaminosis and Vitamin C Deficiency in Pediatric Patients Undergoing Cardiopulmonary Bypass.

Vitamin C levels are known rapidly decrease in adult critical illness. Vitamin C scavenges free radicals, provides critical protection of the endothelial barrier, and improves endothelial responsiveness to catecholamines. Children with congenital heart disease and undergoing cardiac surgery might be at increased risk for low circulating vitamin C levels. A prospective single-center observational study investigated perioperative changes in vitamin C levels in critically ill Children who underwent congenital heart surgery using CPB. Vitamin C serum levels were collected preoperatively and postoperatively (upon admission to the ICU, 24 and 72 h). Linear mixed-effect model was used to estimate mean circulating concentration of vitamin C and to estimate changes in concentration over time. Primary outcome was change in circulating levels of vitamin C before and after CPB. Secondary outcomes were hospital length of stay (LOS), acute kidney injury (AKI), and illness severity. Forty-one patients with a median age of 4.5 [interquartile range (IQR) 2.6-65.6] months at the time of surgery were consented and enrolled. Median CPB duration was 130 [90-175] minutes, and hospital LOS was 9.1 [5.2-19] days. Mean vitamin C levels (µmol/L) before CPB, at PICU admission, 24 h, and 72 h were 82.0 (95% CI 73.4-90.7), 53.4 (95% CI 44.6,62.0), 55.1 (95% CI 46.3,63.8), and 59.2 (95% CI 50.3,68.1), respectively. Upon postoperative admission to the PICU, vitamin C levels decreased by 28.7 (95% CI 20.6-36.8; p < 0.001) µmol/L, whereas levels at 24 and 72 h recovered and did not differ substantially from concentrations reported upon PICU admission (p > 0.15). Changes in vitamin C concentration were not associated with CPB time, STAT mortality category, age, or PIM3. Three patients had post-CPB hypovitaminosis C or vitamin C deficiency. Reduction in vitamin C levels was not associated with hospital LOS (p = 0.673). A 25 µmol/L decrease in vitamin C levels upon PICU admission was associated with developing AKI (aOR = 3.65; 95% CI 1.01-18.0, p = 0.049). Pediatric patients undergoing cardiac surgery with CPB showed decreased vitamin C levels during the immediate postoperative period. Effects of hypovitaminosis C and vitamin C deficiency in this population remain unclear.

Scurvy: Rediscovering a Forgotten Disease.

Scurvy is a nutritional deficiency caused by low vitamin C levels that has been described since ancient times. It leads to a varied presentation, affecting multiple organ systems due to its role in the biochemical reactions of connective tissue synthesis. Common manifestations include gingival bleeding, arthralgias, skin discoloration, impaired wound healing, perifollicular hemorrhage, and ecchymoses. Although there has been a dramatic reduction in the prevalence of scurvy in modern times owing to vitamin C supplementation and intake, sporadic cases still occur. In developed countries, it is mainly diagnosed in the elderly and malnourished individuals and is associated with alcoholism, low socio-economic status, and poor dietary habits. Scurvy has been an unusual cause of gastrointestinal (GI) bleeding among other GI manifestations. It can be adequately treated and prevented via vitamin C supplementation.

Scurvy in a Pediatric Patient Unable to Bear Weight: A Case Report.

Pediatric scurvy is uncommon in the twenty-first century but cases have been reported in children with neurodevelopmental issues and restricted diets. We are reporting a two-year and nine-month-old boy who had a coronavirus disease (COVID) infection and then presented with a refusal to walk. By careful history-taking, he was found to have a restricted diet, speech delay, and gum bleeding suggestive of scurvy, which was confirmed by extremely low levels of ascorbic acid. In this case, the diagnosis of scurvy was established before establishing the diagnosis of neurodevelopmental delay. Treatment with ascorbic acid resulted in a remarkable improvement in his symptoms. This case highlights the importance of collecting a thorough history, connecting exam findings to the history, and including scurvy in differential diagnoses for the presentation of inability to bear weight.

Chronic Recurrent Multifocal Osteomyelitis Mimicking Scurvy in a Child: A Case Report.

Scurvy is a rare clinical syndrome resulting from prolonged vitamin C deficiency and is uncommon in the Gulf area. It can present with non-specific symptoms, making diagnosis and treatment challenging. In pediatric patients, symptoms may include weight loss, lethargy, low-grade fever, anemia of varying degrees, easy bruising or bleeding, joint and muscle pain, and poor wound healing. Despite advances in healthcare in many Gulf countries, nutritional deficiencies can still occur in certain populations. Therefore, it is important for pediatricians, orthopedists, rheumatologists, and radiologists to consider scurvy in the evaluation of children with low-grade, multisystemic involvement. We report a case of a six-year-old boy who presented to the emergency department (ED) multiple times with progressive right (RT) leg pain. The clinical picture and imaging findings suggested chronic recurrent multifocal osteomyelitis (CRMO). Despite symptom progression, scurvy was ultimately diagnosed and treatment with vitamin C led to rapid resolution of his symptoms. This case highlights the importance of considering scurvy in the differential diagnosis of children with multisystemic involvement, especially in regions where nutritional deficiencies may be more prevalent.
