Common Oral Conditions: A Review.

Importance: Dry mouth, oral candidiasis, and recurrent aphthous ulcers are 3 of the most common oral conditions that may be associated with patient discomfort, decreased quality of life, and morbidity. Observations: In a meta-analysis of 26 population-based cohort and cross-sectional studies, the global prevalence of dry mouth symptoms was 23% (95% CI, 18% to 28%), placing individuals at risk of oral candidiasis, dental caries, dysgeusia, masticatory/speech impairment, and oropharyngeal dysphagia. Dry mouth is associated with using more than 3 oral medications per day (odds ratio [OR], 2.9 [95% CI, 1.4 to 6.2]), head and neck radiation, and Sjögren disease. Symptoms may include difficulty swallowing and speaking, thirst, and halitosis. Dry mouth is associated with an 11.5% (95% CI, 3.6% to 27%) higher risk of oral candidiasis, based on a meta-analysis of 6 observational cohorts. Management of dry mouth includes mechanical salivary stimulants, oral moisturizers, and/or systemic sialagogues. Oral candidiasis is an opportunistic fungal infection caused by overgrowth of the Candida genus with C albicans, which accounts for 76.8% of infections. The prevalence of oral candidiasis is higher in patients who are immunosuppressed, for example, those with HIV (35% [95% CI, 28% to 42%]) and those with salivary gland hypofunction (OR, 3.02 [95% CI, 1.73 to 5.28]). Common risk factors associated with oral candidiasis include use of antibiotics (P = .04) and oral mucosal disorders such as lichen planus. Oral burning and dysgeusia are common symptoms of oral candidiasis. Treatment includes addressing risk factors and use of topical and/or systemic antifungal medications. Recurrent aphthous stomatitis is characterized by symptomatic round or oval oral ulcers, which are covered by a gray-white fibrin layer and encircled by an erythematous ring. A meta-analysis of 10 case-controlled studies revealed an increased risk of recurrent aphthous stomatitis associated with polymorphism of IL-1ß (+3954C/T) (OR, 1.52 [95% CI, 1.07 to 2.17]) and IL-1ß (-511C/T) (OR, 1.35 [95% CI, 1.09 to 1.67]). Another meta-analysis of 9 case-control studies reported that patients with recurrent aphthous stomatitis had a higher frequency of nutritional deficiencies, including vitamin B12 (OR, 3.75 [95% CI, 2.38 to 5.94]), folic acid (OR, 7.55 [95% CI, 3.91 to 14.60]), and ferritin (OR, 2.62 [95% CI, 1.69 to 4.06]). Recurrent aphthous stomatitis can be associated with systemic diseases. A meta-analysis of 21 case-control studies revealed that celiac disease is associated with a higher incidence of recurrent aphthous stomatitis (25% vs 11%; OR, 3.79 [95% CI, 2.67 to 5.39]; P <.001). Topical corticosteroids are first-line agents to manage recurrent aphthous stomatitis; however, systemic medications may be necessary in more severe cases. Conclusions and Relevance: Dry mouth, oral candidiasis, and recurrent aphthous ulcers are common oral conditions that may be associated with patient discomfort, decreased quality of life, and morbidity. First-line treatment includes over-the-counter sialagogues for dry mouth, topical antifungals for oral candidiasis, and topical corticosteroids for aphthous ulcers. Oral conditions that do not improve with first-line treatment may require treatment with systemic medications.

Systemic and local effect of oxidative stress on recurrent aphthous stomatitis: systematic review.

Recurrent aphthous stomatitis (RAS) is a chronic and recurrent inflammatory disease of the mouth. It is characterised by the appearance of painful ulcers in the oral mucosa. RAS is believed to be a multifactorial disease with genetic predisposition, environmental factors and alterations in the immune system. Oxidative stress, caused by an imbalance between free radicals and the antioxidant system, also appears to be involved in the pathogenesis of RAS. Several risk factors, such as smoking, iron and vitamin deficiency and anxiety, may contribute to the development of the disease. Understanding the underlying mechanisms may help in the prevention and treatment of RAS. We searched PubMed, Scopus and Web of Science databases for articles on oxidative stress in patients with RAS from 2000 to 2023. Studies analysing oxidant and antioxidant levels in the blood and saliva of RAS patients and healthy controls were selected. Of 170 potentially eligible articles, 24 met the inclusion criteria: 11 studies on blood samples, 6 on salivary samples and 7 on both blood and salivary samples. Multiple oxidative and antioxidant markers were assessed in blood and saliva samples. Overall, statistically significant differences were found between RAS patients and healthy controls for most markers. In addition, increased oxidative DNA damage was observed in patients with RAS. Patients with RAS show elevated levels of oxidative stress compared to healthy controls, with a significant increase in oxidative markers and a significant decrease in antioxidant defences in saliva and blood samples.

Determinants and inequality of recurrent aphthous stomatitis in an Indonesian population: a cross sectional study.

INTRODUCTION: Recurrent Aphthous Stomatitis (RAS) is the most common type of ulceration in the oral cavity which can occur due to several factors. AIMS: To determine the factors related to the incidence of RAS and examine the social class inequality in RAS among the Indonesian population using data from the fifth wave of the Indonesian Family Life Survey (IFLS5) in 2014. METHODS: This study is a descriptive study with a cross-sectional design using secondary data from IFLS5 data in 2014 (n = 28,410). Socio-economic position (SEP) was calculated by Adult Equivalent Scale and categorized into 4 classes. Outcome is RAS. Mediating factors were psychosocial (stress), eating behavioral (food consumption), and systemic diseases. Descriptive analysis, chi-square and a series of logistic regressions were performed to analyze the data. Odds ratio (OR) and 95% confidence interval (CI) were used to report the results. RESULTS: Only 18.39% of IFLS5 respondents experienced the incidence of recurrent aphthous stomatitis in 2014. The bivariate (chi-square) results showed that there was a relationship between the incidence of RAS and the related independent variables. Logistic regression showed the highest possibility of RAS in respondents aged 18-34 years, female, unmarried, high school education level, living in the city, having frequent stress levels, having food habits that frequently drinking soda, sweet foods, chili sauce, fried food and has systemic diseases such as, asthma, cancer, rheumatism, and digestion. The lowest SEP group had the highest probability of occurrence of RAS over the other groups among the different models. CONCLUSIONS: There are several factors that determine the incidence of RAS. There was a monotonic gradient of inequality in RAS according to SEP group. This study might be useful to provide information regarding the relationship of determinants factors with the incidence of RAS to prevent it and promote oral health in the future.

Hematological parameters, obesity, stress and oxidant - antioxidant indicators in patients with or without recurrent aphthous stomatitis: A case control study.

INTRODUCTION: Recurrent Aphthous Stomatitis (RAS) is a frequent chronic disease of the oral cavity that affects 5-25 % of the population with a plethora of predisposing factors. Despite its equivocal etiology, immune alterations, hematologic deficiencies and oxidative stress has been reported to be significant etiologic factors. Stress and obesity are other environmental factors that have been studied to understand associations with RAS. OBJECTIVES: This study investigated the association of stress, hematologic parameters, oxidative indices and other selected salivary factors in a case control study on RAS Methods: Twenty-two participants each in both case and control groups were recruited with saliva and serum samples collected from them after a self-administered Recent Life Changing Questionnaire (RLCQ). OHI-S and salivary flow rate (SFR) were calculated with selected hematologic parameters and oxidative indices such as Total oxidant (TOS) and anti-oxidant (TAS) levels and their ratio - Oxidative Stress Index (OSI). Anti-oxidative indices of Ferric-Reducing Antioxidant Power (FRAP) and Glutathione Peroxidase Activity (GsPHx) were also estimated. RESULTS: The RAS group had a significantly higher RLCQ scores at a median of 145 more than the control (57.5). There was no significant in their obesity indices, however there was a significant higher mean in the ESR (p< 0.0001) and Vit B12 (p = 0.0001); OHI-S was also significantly higher in the RAS group with a median of 1.65. Both the salivary and serum TOS were significantly higher in the RAS (10.0 ± 3.8, 15.4 ± 8.9) compared to the control group (7.92 ± 1.49, 9.56 ± 3.5). GsPHx activity was significantly higher in both the saliva and serum in the control group (0.08 ± 0.08, 0.19 ± 0.11) while nil significant difference was found in the FRAP activity. Regression showed most important variables to be the salivary GsPHx activity, followed by serum OSI and GsPHx activity. CONCLUSION: The oxidative indices of TOS, TAS and GsPHx can serve as significant biomarkers in detecting RAS. This further corroborates the role of immune dysregulation in the etiology and predisposition to RAS.

Adamantiades-Behçet disease: Between dermatology and ophthalmology.

Adamantiades-Behçet disease is an inflammatory, vascular disease of unknown etiology. The disease is named after two physicians, Benediktos Adamantiades and Hulȗsi Behçet, who both made significant contributions to the study of the disease. It was probably first described by Hippocrates in 500 BCE. Adamantiades-Behçet disease is most common in the region encompassing the ancient trade route known as the Silk Road. In Turkey, the disease is estimated to affect 80 to 370 people per 100,000 inhabitants, and it is also the country with the highest incidence rate. The frequency of the disease associated with the clinical picture differs from the origin of the onset. The disease is characterized by recurrent aphthous ulcers of the mouth, genitals, skin lesions, and eye lesions. The disease process can also involve other organs, including the joints, nervous system, large vessels, heart, and gastrointestinal tract. Aphthous oral ulcers appear as the first harbinger of the disease and affect almost all patients (97%-99%). The scientific interest in Adamantiades-Behçet disease has increased exponentially in the past decade.

Acute Immune-Mediated Lesions of the Oral Cavity.

Although acute immune-mediated lesions of the oral cavity (AIML) can have an onset over several months, they often demonstrate rapid onset and can be self-limited. Despite the self-limiting nature of some disorders, patients with AIML can have significant pain and multisystem involvement. It is vital for the oral health care provider to arrive at the proper diagnosis with distinction from overlapping conditions, as the oral manifestations may be harbingers of more serious systemic complications.

Evaluation of biochemical variables in patients with recurrent aphthous stomatitis.

PURPOSE: We investigated the effects of various biochemical agents on the etiopathogenesis of recurrent aphthous stomatitis (RAS). METHODS: We enrolled 70 RAS patients and 70 healthy volunteers. Peripheral venous blood samples were collected. We performed complete blood counts, then measured the levels of ferritin, vitamin B12, iron, magnesium, phosphorus, calcium, thyroid-stimulating hormone, T3, T4, and 25-hydroxy D3. RESULTS: The groups did not differ in terms of age (p = 0.912) or sex (p = 0.612). The levels of ferritin and 25-hydroxy vitamin D were significantly lower in RAS patients (both p Ë‚ 0.05). CONCLUSION: Vitamin D and/or ferritin deficiency may induce RAS. Measurements of vitamin D and ferritin may assist diagnosis and follow-up.

[Marshall syndrome]. / Syndrome de Marshall.

MARSHALL SYNDROME. Marshall syndrome also known as PFAPA syndrome belongs to the group of autoinflammatory diseases. The acronym reflects the main clinical features of the disease: periodic fever, aphthous stomatitis, pharyngitis, and adenitis. It is the most common autoinflammatory disease, beginning between 1 and 5 years of age. There is little or no impact on growth, but the recurrence of febrile seizures can compromise the quality of life of patients. Clinical diagnosis meets positive and exclusion criteria. Putting it correctly allows a reassuring framework of care and avoids many unnecessary antibiotic treatments. Corticosteroid therapy is the reference treatment for the crisis. Tonsillectomy associated with adenoidectomy can be discussed but is not systematically recommended in this pathology, which is generally benign and most often heals spontaneously with age.

SYNDROME DE MARSHALL. Le syndrome de Marshall, aussi connu sous le nom de syndrome PFAPA, appartient au groupe des maladies auto-inflammatoires. L'acronyme reflète les principales caractéristiques cliniques de la maladie : fièvre périodique, aphtes, pharyngite, adénite. Il s'agit de la maladie auto-inflammatoire la plus fréquente, débutant entre 1 et 5 ans. Il n'y a pas ou peu de retentissement sur la croissance, mais la récurrence des accès fébriles peut obérer la qualité de vie des patients. Le diagnostic clinique répond à des critères positifs et d'exclusion. Bien poser celui-ci permet de poser un cadre de prise en charge rassurant pour l'entourage et d'éviter de nombreux traitements antibiotiques inutiles. La corticothérapie est le traitement de référence de la crise. L'amygdalectomie associée à l'adénoïdectomie peut être discutée mais n'est pas recommandée de façon systématique dans cette pathologie en général bénigne et guérissant le plus souvent spontanément avec l'âge.

Oral manifestations serve as potential signs of ulcerative colitis: A review.

As an immune dysregulation-related disease, although ulcerative colitis (UC) primarily affects the intestinal tract, extraintestinal manifestations of the disease are evident, particularly in the oral cavity. Herein, we have reviewed the various oral presentations, potential pathogenesis, and treatment of oral lesions related to UC. The oral manifestations of UC include specific and nonspecific manifestations, with the former including pyostomatitis vegetans and the latter encompassing recurrent aphthous ulcers, atrophic glossitis, burning mouth syndrome, angular cheilitis, dry mouth, taste change, halitosis, and periodontitis. Although the aetiology of UC has not been fully determined, the factors leading to its development include immune system dysregulation, dysbiosis, and malnutrition. The principle of treating oral lesions in UC is to relieve pain, accelerate the healing of lesions, and prevent secondary infection, and the primary procedure is to control intestinal diseases. Systemic corticosteroids are the preferred treatment options, besides, topical and systemic administration combined with dietary guidance can also be applied. Oral manifestations of UC might accompany or precede the diagnosis of UC, albeit with the absence of intestinal symptoms; therefore, oral lesions, especially pyostomatitis vegetans, recurrent aphthous ulcer and periodontitis, could be used as good mucocutaneous signs to judge the occurrence and severity of UC, thus facilitating the early diagnosis and treatment of UC and avoiding severe consequences, such as colon cancer.

The expression of TNF-α in recurrent aphthous stomatitis: A systematic review and meta-analysis.

OBJECTIVE: The pathogenesis of recurrent aphthous stomatitis (RAS) is related to an increase of pro-inflammatory cytokine, namely tumor necrosis factor α (TNF-α). This cytokine plays an important role in the development of ulcer lesions, both in saliva, tissues and blood. This systematic review analyzed the differences of TNF-α in lesions, salivary and blood and can be used as a reliable method of diagnosis for RAS. METHODS: A comprehensive search of PubMed, Scopus databases, Web of Science, Scielo, Google Scholar and Embase with keywords. The inclusion criteria were studies that assessed the saliva, serum, and RAS lesion, with the outcome reporting the mean of saliva, serum and tissue expression of TNF-α. The risk of bias was also assessed. RESULT: Healthy individuals showed significantly lower TNF-α than RAS (SMD = -1.517, 95% CI [-2.25, -0.78]). Although there is a significant difference between sample (i.e., saliva, serum) and detection type (i.e., cytometry bead array, ELISA), both methods can detect a significant difference in TNF-α between healthy individuals and RAS patients. CONCLUSIONS: The TNF-α is a useful diagnostic marker for RAS. We encourage saliva to detect changes in TNF-α during ulceration as it provides accuracy, reliability, and non-invasive procedure compared to a blood draw.

Role of biologics in refractory recurrent aphthous stomatitis.

Refractory recurrent aphthous stomatitis (RRAS) manifests as severe ulcerative lesions of the oral mucosa with poor healing and a poor response to conventional therapy, with or without systemic diseases. Its treatment remains a clinical challenge owing to the lack of effective therapies. Recently, biologics have emerged as promising targeted therapies for RRAS. The biologics targeting specific inflammatory pathways involved in the pathogenesis of RRAS, including tumor necrosis factor-alpha inhibitors and interleukin inhibitors, offer a more precise and promising therapeutic approach for RRAS. These targeted therapies have been shown to promote healing and decrease recurrence frequency in, and improve the quality of life of patients with RRAS. Herein, the types and mechanisms of biologics currently used to treat RRAS have been reviewed; furthermore, the dose, duration, therapeutic efficacy, and adverse effects of RRAS with or without certain associated systemic diseases, and the current problems and future directions have been discussed.

Common Oral Lesions.

Familiarity with common oral conditions allows clinicians to observe and treat patients in the primary care setting or refer to a dentist, oral surgeon, otolaryngologist, or other specialist. Recurrent aphthous stomatitis (canker sores) is the most common ulcerative condition of the oral cavity. Recurrent herpes simplex labialis and stomatitis also commonly cause oral ulcers. Corticosteroids, immunocompromise, antibiotics, and dentures can predispose patients to oral candidiasis. Benign migratory glossitis (geographic tongue) occurs in up to 3% of the population but generally lacks symptoms, although some people experience food sensitivity or a burning sensation. Hairy tongue is associated with a low fiber diet, tobacco and alcohol use, and poor oral hygiene in older male patients. Generally, hairy tongue is asymptomatic except for an unattractive appearance or halitosis. Tobacco and alcohol use can cause mucosal changes resulting in leukoplakia and erythroplakia. These can represent precancerous changes and increase the risk of squamous cell carcinoma. Mandibular and maxillary tori are common bony cortical outgrowths that require no treatment in the absence of repeat trauma from chewing or interference with dentures. Oral lichen planus occurs in up to 2% of individuals and can present as lacy reticulations or oral erosions and ulcerations. Traumatic buccal mucosal fibromas and labial mucoceles from biting can be excised.

Aphthous Stomatitis as an Uninvited Guest after Dental Implant Surgery: A Case Series.

Objectives - Aphthous stomatitis is one of the most common ulcerative lesions in the oral cavity. The aim of this study was to report the characteristics of patients with aphthous stomatitis after dental implantation. Patients and Method - The study included 14 patients who were diagnosed with aphthous stomatitis. The subjects were analyzed with the respect to age, sex, patient's general health status, type, number, location, and duration of the ulcers and the number of dental implants. Results - Of the 14 cases, 64.3% were female and 35.7% were male. The mean age of patients was 57.7. In terms of general health status, 64.3% of patients did not have a remarkable disease; however, 14.3%, 14.3%, and 7.1% of cases had diabetes, hypothyroidism, and cardiac disease, respectively. The majority of the lesions have been presented as minor type (85.7%) and the mean number of the ulcers was 2.5. Labial mucosa has been affected more frequently (71.4%), followed by tongue and floor of the mouth. The most lesions (42.8%) were occurred one day after dental implant surgery. The mean number of dental implants was 3.1. Conclusion - Presence of apthous ulcers should be considered by dentists as a potential postoperative complication of dental implantation.

Dental enamel defects and oral cavity manifestations in Asian patients with celiac disease.

BACKGROUND: While the small intestine is the main site of disease, many other organs are affected by celiac disease (CeD). Dental enamel defects (DED) are common in patients with CeD, and these are one of the indicators of CeD, even when no other symptom of CeD is present. Data on dental and oral cavity manifestations in Asian patients with CeD are scanty. The purpose of the current study was to evaluate dental and oral manifestations in Asian patients with CeD. METHODS: We recruited 118 patients with biopsy-confirmed CeD (36 treatment naïve and 82 on follow-up for at least 1 year on gluten-free diet [GFD]) and 40 controls. Diagnosis was made as per the standard criteria. Oral and dental manifestations were evaluated by a dental surgeon. The DED were evaluated according to Aine's criteria. RESULTS: Overall higher number of patients with CeD (66.9%), both treatment naïve (69.4%) and those on GFD (65.8%) had DED in comparison to controls (20%) (odds ratio, 8.1, 95% confidence interval [CI] 3.4-19.2; p<0.001). Specific/bilaterally symmetrical DED were significantly higher in patients with CeD than controls. Recurrent aphthous ulcers were also significantly higher in patients with CeD. Approximately 80.6% and 63.4% treatment-naïve patients and those on GFD, respectively reported dry mouth sensation, which was significantly higher than the controls. CONCLUSION: Almost two-third of patients with CeD had DED. Physicians and dietitians caring for patients with CeD should be trained in identification of DED and other oral manifestations of CeD.

Decrease in treatment intensity predicts worse outcome in patients with locally advanced head and neck squamous cell carcinoma undergoing radiochemotherapy.

PURPOSE: Radiochemotherapy (RCT) is an effective standard therapy for locally advanced head and neck squamous cell carcinoma (LA-HNSCC). Nonetheless, toxicity is common, with patients often requiring dose modifications. METHODS: To investigate associations of RCT toxicities according to CTCAE version 5.0 and subsequent therapy modifications with short- and long-term treatment outcomes, we studied all 193 patients with HNSCC who received RCT (70 Gy + platinum agent) at an academic center between 03/2010 and 04/2018. RESULTS: During RCT, 77 (41%, 95% CI 34-49) patients developed at least one ≥ grade 3 toxicity, including seven grade 4 and 3 fatal grade 5 toxicities. The most frequent any-grade toxicities were xerostomia (n = 187), stomatitis (n = 181), dermatitis (n = 174), and leucopenia (n = 98). Eleven patients (6%) had their radiotherapy schedule modified (mean radiotherapy dose reduction = 12 Gy), and 120 patients (64%) had chemotherapy modifications (permanent discontinuation: n = 67, pause: n = 34, dose reduction: n = 7, change to other chemotherapy: n = 10). Objective response rates to RCT were 55% and 88% in patients with and without radiotherapy modifications (p = 0.003), and 84% and 88% in patients with and without chemotherapy modifications (p = 0.468), respectively. Five-year progression-free survival estimates were 20% and 50% in patients with and without radiotherapy modifications (p = < 0.001), and 53% and 40% in patients with and without chemotherapy modifications (p = 0.88), respectively. CONCLUSIONS: Reductions of radiotherapy dose were associated with impaired long-term outcomes, whereas reductions in chemotherapy intensity were not. This suggests that toxicities during RCT should be primarily managed by modifying chemotherapy rather than radiotherapy.

Serum vitamin B12 associated with vitamin D/25(OH)D in women with recurrent aphthous stomatitis / Vitamina B12 sérica asociada con vitamina D / 25 (OH) D en mujeres con estomatitis aftosa recurrente

Vitamin B12 and Vitamin D deficiency may contribute to recurrent aphthous stomatitis (RAS). Current studies have showed vitamin B12 to be associated with vitamin D in women, however no study has assessed vitamin B12 associated with vitamin D/25(OH)D in women with RAS. Objective: To investigate the association between serum vitamin B12 and vitamin D/25(OH)D in women with RAS. Materials and Methods: Fourty one women with RAS who meet the inclusion criteria participated in this study. The inclusion criteria were women with RAS without other oral diseases. The exclusions criteria were those who have systemic diseases, taking medications or smoked. All subjects underwent venupuncture to draw blood to quantify serum vitamin B12 and vitamin D/25(OH)D. The characteristic of subjects, severity of RAS, serum Vitamin B12 and Vitamin D/25(OH)D were collected and presented descriptively. The correlation between vitamin B12 and Vitamin D/25(OH)D was analyzed using Pearson correlation test with 95% confidence interval. This study was approved by Medical and Health Ethics Committe, Faculty of Medicine, Universitas Gadjah Mada, Yogyakarta, Indonesia. Results: All RAS subjects have normal mean value of serum Vitamin B12 (453.97+154.44pg/ml) and have low mean value of serum vitamin D/25(OH)D (10.79 +3.29ng/ml) categorized as vitamin D deficiency. The Pearson correlation test showed that there was a significant positive correlation between mean serum Vitamin B12 and Vitamin D/25(OH)D (r= 0.313, p<0.05). Conclusion: There is correlation between vitamin B12 and Vitamin D, and a low level of Vitamin D may contribute in RAS in women.

Antecedentes: la deficiencia de vitamina B12 y vitamina D puede contribuir a la estomatitis aftosa recurrente (EAR). Los estudios actuales han demostrado que la vitamina B12 está asociada con la vitamina D en mujeres, sin embargo, ningún estudio ha evaluado la vitamina B12 asociada con la vitamina D/25 (OH) D en mujeres con EAR. Objetivo: investigar la asociación entre la vitamina B12 y la vitamina D / 25 (OH) D sérica en mujeres con RAS. Material y Métodos: Cuarenta y una mujeres con RAS que cumplen con los criterios de inclusión participaron en este estudio. Los criterios de inclusión fueron mujeres con RAS y sin otras enfermedades orales. Los criterios de exclusión fueron aquellos que tenían enfermedades sistémicas, tomaban medicamentos o fumaban. Todos los sujetos se sometieron a una venupuntura para extraer sangre para cuantificar la vitamina B12 y la vitamina D/25 (OH) D en suero. Las características de los sujetos, la severidad del EAR, la concentración de vitamina B12 y la vitamina D/25 (OH) D sérica fueron recolectadas y presentadas descriptivamente. La correlación entre la vitamina B12 y la vitamina D/25 (OH) D se analizó mediante la prueba de correlación de Pearson con un intervalo de confianza del 95%. Este estudio fue aprobado por el Comité de Ética Médica y de Salud, Facultad de Medicina, Universitas Gadjah Mada, Yogyakarta, Indonesia. Resultado: Todos los sujetos con EAR tienen un valor medio normal de vitamina B12 sérica (453,97pg/ml + 154,44pg/ml) y un valor medio bajo de vitamina D sérica/25 (OH) D (10,79 ng/ml + 3,29ng/ml) clasificado como deficiencia de vitamina D. La prueba de correlación de Pearson mostró que había una correlación positiva significativa entre la vitamina B12 media y la vitamina D/25 (OH) D en suero r=0.313, p<0.05). Conclusión: Existe una correlación entre la vitamina B12 y la vitamina D, y un bajo nivel de vitamina D puede contribuir al RAS en las mujeres.
