Association between interleukin family gene polymorphisms and recurrent aphthous stomatitis risk.

The present study was aimed at identifying the association between interleukin family gene polymorphisms and recurrent aphthous stomatitis (RAS) risk using a meta-analysis. We searched the PubMed, web of science, Embase and ScienceDirect-Elsevier databases for research on the interleukin polymorphism and RAS risk. In total 12 studies were included to investigate the relationships between RAS risk and six polymorphisms by calculating pooled odds ratios (ORs) and 95% confidence intervals (CIs). A significant association was found between IL-1β+3954C/T polymorphism and RAS risk. A high risk of RAS was found in RAS patients with the G allele or GG genotype of IL-6-174 polymorphism. Low risk of RAS was found in the C allele of IL-10-592C/A polymorphism under an allele model, but a high risk of RAS was found in IL-10-1082G/A polymorphism. In the subgroup analysis, no correlation was found between the IL-10-1082 polymorphism and RAS risk in the caucasian population with the allele model. In conclusion, an IL-1β+3954C/T polymorphism was determined to be related to susceptibility to RAS, and individuals with the G allele and GG genotype of IL-6-174 or the A allele of IL-10-592 or the G allele of IL-10-1082 appeared to be more vulnerable to developing RAS.

Gastric parietal cell and thyroid autoantibodies in patients with Behcet's disease.

Gastric parietal cell antibody (GPCA), thyroglobulin antibody (TGA), and thyroid microsomal antibody (TMA) were rarely examined in Behcet's disease (BD) patients. This study mainly assessed the frequencies of serum GPCA, TGA, and TMA positivities in 63 BD patients. The frequencies of serum GPCA, TGA, and TMA positivities in 63 BD patients, 19 major-typed recurrent aphthous stomatitis (RAS)/BD (major RAS/BD) patients, 44 minor-typed RAS/BD (minor RAS/BD) patients, 520 RAS patients, and 126 healthy control subjects were calculated and compared. We found that 14.3%, 20.6%, and 20.6% of 63 BD patients, 21.1%, 21.1%, and 26.3% of 19 major RAS/BD patients, 11.4%, 20.5%, and 18.2% of 44 minor RAS/BD patients, 11.5%, 18.5%, and 18.3% of 520 RAS patients, and 1.6%, 2.4%, and 2.4% of 126 healthy control subjects had serum GPCA, TGA, and TMA positivities, respectively. BD, major RAS/BD, minor RAS/BD, and RAS patients all had significantly higher frequencies of serum GPCA, TGA, and TMA positivities than healthy control subjects (all P-values<0.05). However, there were no significant differences in different serum autoantibody frequencies between BD, major RAS/BD, or minor RAS/BD patients and RAS patients. Of 16 TGA/TMA-positive BD patients whose serum thyroid-stimulating hormone (TSH) levels were measured, 87.5%, 6.3%, and 6.3% of these TGA/TMA-positive BD patients had normal, lower, and higher serum TSH levels, respectively. Approximately 35% BD patients have serum GPCA/TGA/TMA positivity. However, BD patients do not have significantly higher frequencies of serum GPCA, TGA, and TMA positivities than RAS patients.

Hematinic deficiencies in patients with recurrent aphthous stomatitis: variations by gender and age.

BackgroundThe aim of this study was to evaluate the association between hematinic deficiencies and recurrent aphthous stomatitis (RAS).Material and Methods517 RAS patients and 187 healthy controls were enrolled in the present study. Hematinic deficiencies, including serum ferritin, folic acid, and vitamin B12 deficiencies were assessed for each participant. Gender and age were taken into account and the collected data were statistically analysed.ResultsCompared with the healthy controls, a significantly higher overall frequency of hematinic deficiencies was found in RAS patients (p<0.001). When gender and age were taken into account, significant differences in hematinic deficiencies were observed among RAS patients. Serum ferritin deficiency was much more common in young and middle-aged female RAS patients (age<60). Serum folate deficiency and serum vitamin B12 deficiency were both much more common in the young adult group of male RAS patients (21–40 years of age). Logistic regression analysis revealed that both gender and age have significant correlation with the presence of hematinic deficiencies in the RAS patients.ConclusionsSignificant variations in hematinic deficiencies were demonstrated in RAS patients across different genders and age groups. We suggest that further studies on the hematinic deficiencies of RAS patients should take into account the gender and age of participants. Key words:Recurrent aphthous stomatitis, hematinic deficiencies, gender, age.

Salivary levels of TNF-α in patients with recurrent aphthous stomatitis: A cross-sectional study.

Background. Recurrent aphthous stomatitis (RAS) is a disorder characterized by recurring ulcers involving the oral mucosa in patients with no other signs of disease. The current concept of etiopathogenesis is that RAS is a clinical syndrome with several possible etiologies. The process seen in RAS is probably initiated through an as yet unidentified antigenic stimulation of the mucosal keratinocytes, which stimulates secretion of T-cell activation cytokines ‒ interleukins and tumor necrosis factor alpha (TNF-α). TNF-α causes inflammation by its effect on endothelial cell adhesion and neutrophil chemotaxis. The rele-vance of TNF-α to the pathogenesis of RAS has stemmed from the observations that anti- TNF-α drugs such as thalidomide and pentoxifylline have been found to be effective in the treatment of RAS. Therefore, the present study was an attempt to measure the levels of salivary TNF-α in patients with RAS, which will reflect the local production of cytokines at the site of the disease. The aim was to evaluate the salivary levels of TNF-α in patients with recurrent aphthous stomatitis. Methods. The study comprised of 60 subjects, of whom 30 clinically proven RAS patients of either sex were selected as cases and 30 healthy, age- and gender- matched subjects were selected as controls. After taking informed consent, 5 mL of unstimulated saliva were collected from both the study and control group subjects. Determination of salivary TNF-α levels was carried out by Enzyme-Linked Immunosorbent Assay (ELISA) and expressed in pg/mL. Statistical analysis of the RAS and control groups was carried out using unpaired t-test. Gender-wise comparison of salivary TNF-α levels in the study and control groups was carried out using one-way ANOVA. Results. Mean salivary TNF-α levels were significantly higher in the RAS group compared to the control group (P<0.001). It was also revealed that the mean salivary TNF-α levels in females were significantly higher than in males in the study group (PP<0.05). Conclusion. It is fair to suggest that TNF-α plays a very important mediatory role in the pathogenesis of RAS and may play an important role in the search for a definitive treatment for the disease.

Evaluation of serum zinc levels in patients with recurrent aphthous stomatitis (RAS)

BackgroundRecurrent aphthous stomatitis (RAS) is an ulcerative disease of the oral mucosa without a clearly defined etiology. The aim of the study was to evaluate the serum zinc levels in patients with RAS in comparison to healthy controls and to validate the association between zinc levels and the course of RAS.MethodsSeventy-five patients with RAS and 72 controls underwent full dental examination. Serum zinc levels were determined by flame atomic absorption spectroscopy (F AAS). The results were statistically analyzed with Kruskal-Wallis, Mann-Whitney, chi-square tests and the test of difference between the two rates of structure with p < 0.05 as a significance level (Statistica 10, StatSoft®).ResultsNo statistically significant differences were detected in serum zinc levels between RAS patients and healthy controls. The mean serum zinc concentration was found to be 84.2 μg/dL in RAS group and 83.9 μd/dL in controls, within the accepted norms. Zinc deficiency was observed in 10.7% patients from the RAS group and in 6.9% controls. No significant differences in serum zinc levels were found between patients when the course of the disease was considered.ConclusionsSerum zinc concentrations did not differ significantly in RAS patients and in healthy controls and it did not influence the course of the disease. Therefore, zinc does not appear to be an important modifying factor in the development of RAS.

Effect Of 5% Binahong Leaves Extract Gel On Minor Recurrent Aphthous Stomatitis

Introduction: Recurrent aphthous stomatitis (RAS) is recurrent oral ulcers. RAS pain make patient difficult to speak, eat, swallow, and lowered patient's quality of life. Binahong leaves is a traditional medicine that has anti-inflammatory, antibacterial, covering agents and antioxidants effect that can be used to cure RAS. The purpose of this study was to determine the effect of binahong leaves extract gel for minor RAS healing. Materials and Methods: This study was an experimental study with pretest-posttest control group design which involved 20 RAS patients visiting USU Dental Hospital. Data collected by initial examination then controlled every day for the next three days. Pain scale is measured with visual analog scale. Erythematous halo is measured by the presence or absence of erythema. Ulcer size is measured by measuring the largest diameter of ulcer. Patient was asked to apply the extract thinly with cotton bud. Analysis of the data used Friedman Test and Cochran Test to determine the difference before and after treatment. Results: The result showed significant reduction in pain scale p = 0.001 (p&lt;0.05), erythema halo p = 0.001 (p&lt;0.05), and ulcer size p = 0.001 (p&lt;0.05). There is a reduction in pain scale, erythema halo, and ulcer size at the time of initial examination to first, second and third control. Conclusion(s): The use of 5% binahong leaves extract gel was effective to reduce pain, erythema halo, and ulcer size of minor RAS.

A Follow-up Study of Clinical Characteristics of Recurrent Aphthous Stomatitis Patients Treated with Herbal Medicine

Objectives The purpose of this study was to report the long-term efficacy of herbal medicine for treatment of patients with recurrent aphthous stomatitis (RAS). Methods We reviewed the clinical records of 17 patients with RAS who visited the Oral Diseases Clinic of Kyung Hee University Korean Medicine Hospital from September 1st, 2014 to August 29th, 2017. The patients were treated with herbal medicine for more than 3 consecutive weeks, followed by a telephone survey. We evaluated the clinical characteristics of RAS, and compared the short-term and long-term efficacy of herbal medicine treatment. Results After treatment with herbal medicine, the clinical characteristics improved in the 17 patients with RAS, especially in terms of the duration and interval of recurrence. Prolonged effects were reported upon the follow-up telephone survey. Conclusion Herbal medicine treatment may have a long-term effect in patients with RAS.

Immune response of patients with recurrent aphthous stomatitis challenged with a symbiotic.

There are indications that Th1 polarization of immune response plays an important role in the pathogenesis of recurrent aphthous stomatitis (RAS), and that the use of probiotics can stimulate immune regulatory activity, influencing the course of the disease. The aim of this study was to characterize the initial immune profile of RAS patients and evaluate clinical and serological response following a challenge with symbiotic treatment containing fructooligosaccharide, Lactobacillus, and Bifidobacterium. The immune responses of the 45 patients with RAS, submitted to symbiotic or placebo for 120 days, in relation to 30 RAS-free controls, were evaluated over a period of 6 months. Peripheral blood was collected from all patients at 0 (T0), 120 (T4), and 180 days (T6) after the start of treatment and Th1 (IL12-p70, IFN-γ), Th2 (IL-4), Treg (IL-10), Th17 (IL-17A), inflammatory (TNF-α, IL-6)-associated cytokines, and clinical parameters were quantified. At T0, significant differences were found in the serological levels of the IFN-γ, IL-4, and IL-6 cytokines of the RAS patients in comparison with the controls. It was observed that the cytokine profile of the RAS group was comprised of 2 distinct clusters: a pure Th2 and a Mixed (Th1/Th2) subtype and that symbiotic treatment induced an improvement in pain and an increase in IFN-γ levels, producing a reduction in Th2 response. In RAS, symbiotic treatment based on a fructooligosaccharide, Lactobacillus, and Bifidobacterium composition produced an alteration in the Th2 serological immune profile in the direction of Th1 and improved pain symptomatology.

Patient-reported outcome measures in recurrent aphthous stomatitis: A critical assessment of quality properties.

To analyse the range of existing patient-reported outcome measures (PROMs) used in studies of recurrent aphthous stomatitis (RAS) and to evaluate their quality properties via the assessment of psychometric properties and interpretability. Electronic databases were searched to identify relevant publications related to PROMs used in RAS. Publications were selected based on predefined criteria. All identified PROMs were then classified by measuring concepts and assessed for instrument characteristics and evidence for quality properties for RAS patients. Twenty-eight PROMs were used in studies of RAS patients. Instruments focused upon oral symptoms (n=4), psychosocial status (n=15) and quality of life (n=9). Five PROMs (Oral Health-related Quality of Life-UK, Chronic Oral Mucosal Disease Questionnaire, Oral Health Impact Profile-14, Medical Outcome Study Short Form-36 and Mumcu's composite index) were found to have some evidence of psychometric performance. No PROMs showed evidence for interpretability of their scores in RAS patients. There was a wide range of PROMs used in clinical studies of RAS. The majority of these PROMs lack evidence of measurement properties and interpretability for RAS patients. Further studies are required to confirm whether these instruments are suitable and useful for this patient group.

Enzymatic antioxidants status in patients with recurrent aphthous stomatitis.

Oxidative stress (OS) has been thought to play a main role in the etiopathogenesis of recurrent aphthous stomatitis (RAS), which is one of the most common oral mucosal diseases characterized by recurrent and painful oral ulcers. The aim of this investigation was to evaluate the enzymatic antioxidants status in patients with RAS in the active stage and remission stage. Ninety-seven patients with idiopathic minor RAS and 102 race-, age- and gender-matched healthy individuals were recruited. All these subjects were allocated to three groups: RAS patients with active lesion (group A); the same patients in group A in the remission stage of RAS (group B); and healthy individuals without RAS (group C). Following an overnight fast, blood samples were obtained. The serum levels of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSHPx) were measured by the spectrophotometric method. Independent-samples t-test and paired t-test were performed for statistical evaluation. The serum levels of SOD, GSHPx, and CAT (83.9 ± 17.1 U/ml, 6687.2 ± 2629.2 U/ml, 1789.7 ± 593.8 U/l) were found to be significantly lower in group A as compared to those of group B (99.8 ± 11.1 U/ml, 9364.1 ± 1607.9 U/ml, 2789.1 ± 1113.4 U/l; P < 0.05) or group C (97.3 ± 12.1 U/ml, 9246.2 ± 2376.1 U/ml, 2819.0 ± 914.8 U/l; P < 0.05). No significant differences were found between group B and group C with respect to any one of these enzymatic antioxidants (P > 0.05). Our results indicate that enzymatic antioxidant defense system is impaired in RAS patients with active lesion and seems to play a crucial role in its pathogenesis.

Recurrent Aphthous Stomatitis: An Assessment of Antioxidant Levels in Plasma and Saliva.

Recurrent Aphthous Stomatitis (RAS) is a common oral mucosal disorder that affects 20% of the population worldwide. Factors such as trauma, stress, genetic, hypersensitivity, nutrition, immune disturbance and hormonal imbalance may disturb the oxidant and antioxidant balance of an organism and precipitate RAS, but the relationships are poorly understood. The purpose of this study was to evaluate the antioxidant status in plasma and saliva of patients with RAS. Forty patients with RAS and forty healthy individuals were included in the study. The levels of antioxidants such as Superoxide Dismutase (SOD), Glutathione Peroxidase (GSHPx) Catalase (CAT) and Uric Acid (UA) were measured in plasma and saliva. Statistical analysis was performed to compare the two groups using independent t-test and ANOVA. Decreased SOD levels were observed in plasma amongst RAS patients (p < 0.03) whereas, increased levels were observed in their saliva (p < 0.001) compared to the control group. A significant difference (p < 0.001) was noticed in GSHPx levels: RAS patients exhibited higher levels in plasma but decreased in saliva compared to the control group. CAT activities and UA levels in saliva (p = 0.015 and p < 0.001 respectively) were observed to be significantly higher in RAS patients. Within the RAS group elevated plasma SOD level (p < 0.006) was found in patients with major ulcers whereas, an increased plasma UA (p < 0.01) level was observed in patients with minor ulcers. The non-equilibrium antioxidant levels observed in both plasma and saliva indicate the antioxidant status of the body is disturbed in patients with RAS.

Interleukin-2, Interferon-gamma Gene Polymorphisms in Recurrent Aphthous Stomatitis.

Recurrent aphthous stomatitis (RAS) is the most common oral ulcerative inflammatory disease with unknown etiology. IL-2 and IFN-γ are secreted by Th1 cells and the elevated levels of them have been reported in RAS. Single nucleotide polymorphisms (SNPs) of IL-2 and IFN-γ genes could alter the cytokine production. The aim of this study was to investigate frequencies of IL-2 and IFN-γ alleles and genotypes in a group of patients with minor-RAS (MiRAS). PCR-SSP method used to type genomic DNA of 64 Iranian patients with MiRAS for IL-2 gene (G -330 T) and (G +166 T) and IFN-γ gene at position UTR5644 (A/T). Frequency of each allele and genotype was compared with control group. IL-2 +166 G allele was significantly lower among patients which was reflected in significantly decreased of GG genotype at this position, while IL-2 +166 T allele was significantly higher among patients, IL-2 GT genotype was also significantly higher in RAS patients. No significant differences were found regarding IL-2 -330 G/T allele frequencies, while IL-2 GT genotype at this position was significantly higher among patients and IL-2 -330 TT genotype was significantly lower among RAS patients. Although no significant differences were found in IFN-γ allele frequencies at UTR5644 (A/T), AT genotype at this position was significantly overrepresented among patients compared with controls. Results of this study suggest that certain SNPs of IL-2 and IFN-γ genes have association with predisposition of individuals to RAS. More studies in different ethnic groups are needed to confirm results of this study.

Assessment of Oxidant-Antioxidant Status and Stress Factor in Recurrent Aphthous Stomatitis Patients: Case Control Study.

Despite its vast occurrence, the aetiology of Recurrent Aphthous Stomatitis (RAS) still remains unknown and its aetiology is multifactorial. The factors believed to be associated with the aetiology of RAS, may disturb the equilibrium of oxidant-antioxidant status of the organism and may accelerate the formation of free radicals, resulting in Oxidative Stress (OS). Psychological stress is believed to act as a triggering factor or modifying factor for RAS. To find whether oxidant-antioxidant status and psychosocial stress play a role in the pathogenesis of RAS. The study was conducted on 60 subjects over a period of one year (August 2014-August 2015) equally divided into two groups-patients with RAS and healthy controls. Psychosocial stress was analyzed by using Recent Life Changes Questionnaire (RLCQ). Saliva was analyzed to evaluate Superoxide Dismutase (SOD) and Glutathione Peroxidase (GSHPx) activities, Malondialdehyde (MDA) and Uric Acid (UA) levels in both the study and the control groups, using UV spectrophotometry. The mean value of salivary SOD and MDA was increased while the activity of GSHPx and UA decreased in the study group when compared to the controls; the difference being statistically significant (p<0.005). The mean RLCQ stress score was also found to be increased in the RAS group, which showed elevated levels of mental stresses when compared to physical stresses. No significant association was observed between SOD, MDA, GSHPx and UA with high levels of stress score (p>0.05). In the study group, no correlation was observed between the study variables and gender, the number of ulcer episodes in one year, the number of ulcers per episode or the duration of ulcers. This study shows that salivary antioxidant levels show a significant difference in response to OS in RAS patients. An increase in levels of psychosocial stress is seen associated with patients with RAS indicating its role as a modifying or triggering factor in the initiation of RAS.

Vitamin D status in recurrent aphthous stomatitis.

IntroductionRecurrent aphthous stomatitis (RAS) is a common chronic inflammatory oral mucosa disease with an unknown cause. However, dysregulation of the immune response seems to play an important role in this disease.AimTo evaluate the vitamin D status in RAS patients and its effects on RAS severity, given the likely immunomodulatory function of vitamin D in the human organism.Material and methodsSixty-six patients with RAS and 66 controls were examined. Immunomodulatory or immunosuppressive treatment and other ulcerative oral diseases were used as exclusion criteria. The severity of RAS was assessed according to the clinical classification of the disease, the number of lesions per flare-up and the length of intervals between the attacks. The serum vitamin D level was established in each participant.ResultsThe mean serum vitamin D (25(OH)D) levels were found to be 16.81 ng/ml in the study group and 19.22 ng/ml in the control group, with no statistically significant difference between the two groups. In the study group, 5 (7.6%) participants were diagnosed with the “normal” vitamin D levels, while 16 (24.2%) had “insufficient” levels and 45 (68.2%) had “deficient” levels. The corresponding distribution in the control group was 8 (12.1%), 18 (27.3%) and 40 (60.6%), respectively. There was no statistical significance in the difference of vitamin D deficits between the study and the control groups. No correlation was detected between the severity of RAS and the serum vitamin D level.ConclusionsVitamin D does not seem to be a trigger factor for RAS occurrence and does not appear to influence the severity of the disease in the studied group.

Soluble Urokinase Plasminogen Activator Receptor (suPAR) in the Diagnosis of Pulmonary Embolism

Traditional methods used by patients for the management of recurrent aphthous stomatitis.

Purpose: Recurrent aphthous stomatitis (RAS) is the most common inflammatory ulcerative condition of oral mucosa. Due to the lack of curative treatment in RAS, patients seek conventional and alternative treatments. Data regarding alternative treatments for RAS used by Indian population is lacking. Hence, the purpose of our study was to determine and describe the various traditional modalities used by patients with RAS. Materials and Methods: Present study was carried out in patients visiting dental hospital from 2015-2016. Detailed case history recording and clinical examination was done by trained professionals. Patients diagnosed with RAS were recruited in our study. Questionnaire was given for RAS patients and data obtained was analysed. Results: A total of 326 patients reported with RAS. The study sample consisted of 171 females (52.5%) and 155 males (47.5%). In our study 198 subjects (60.7%) gave history of receiving treatment and 128 subjects (39.3 %) did not receive any kind of treatment. Out of the 198 subjects, 63(31.8%) of individuals received conventional treatment, alternative treatments were opted by 85(43%) patients and combined treatment modalities were opted by 50(25.2%) patients. Over the counter medications were used by 36 (18%) patients. Treatment outcome was satisfactory according to 137(69%) individuals and treatment was not satisfactory for 61 (31%) patients. Conclusion: This study gives insight into the various traditional medicines used in south India for RAS and to the best of our knowledge, this is first study which describes the same. Our study adds new information to the current literature about traditional medications for RAS.

Is there a role of food additives in recurrent aphthous stomatitis? A prospective study with patch testing.

Recurrent aphthous stomatitis (RAS) is a common disease of the oral mucosa with an unknown etiology. This study aimed to determine if food additives play a role in the etiology of RAS as well as to determine if patch testing can be used to detect which allergens cause RAS. This prospective study included 24 patients with RAS and 22 healthy controls. All the participants underwent patch testing for 23 food additives. In total, 21 (87.5%) RAS patients and 3 (13.6%) controls had positive patch test reactions to ≥1 allergens; the difference in the patch test positivity rate between groups was significant (P<0.05). The most common allergen that elicited positive patch test results in the patient group was cochineal red (n=15 [62.5%]), followed by azorubine (n=11 [45.8%]) and amaranth (n=6 [25%]). The present findings show that food additives might play a role in the etiology of RAS and that patch testing could be a method for determining the etiology of RAS.

Hematinic deficiencies and anemia statuses in recurrent aphthous stomatitis patients with or without atrophic glossitis.

Some of recurrent aphthous stomatitis (RAS) patients had concomitant atrophic glossitis (AG). This study assessed whether RAS patients with AG (AG+/RAS patients) or without AG (AG-/RAS patients) had anemia and hematinic deficiencies and to evaluate whether RAS combined with AG or RAS itself was a significant factor causing anemia and hematinic deficiencies in AG+/RAS or AG-/RAS patients, respectively. The mean corpuscular volume (MCV) and mean blood hemoglobin (Hb), iron, vitamin B12, and folic acid levels were measured and compared between any two of three groups of 160 AG+/RAS patients, 195 AG-/RAS patients, and 355 healthy control subjects. Both AG+/RAS and AG-/RAS patients had significantly lower mean Hb, iron, and vitamin B12 levels as well as significantly greater frequencies of Hb, iron, vitamin B12, and folic acid deficiencies than healthy control subjects. Moreover, AG+/RAS patients had significantly lower mean Hb and serum iron level (for women only) and significantly greater frequencies of Hb and iron deficiencies than AG-/RAS patients. Of 69 anemia AG+/RAS patients, 30 (43.5%) had normocytic anemia and 23 (33.3%) had iron deficiency anemia. Of 38 anemia AG-/RAS patients, 26 (68.4%) had normocytic anemia and 5 (13.2%) had iron deficiency anemia. We conclude that some of AG+/RAS or AG-/RAS patients do have anemia and hematinic deficiencies and AG+/RAS patients do have severer anemia statuses and iron deficiency than AG-/RAS patients. RAS combined with AG or RAS itself does play a significant role in causing anemia and hematinic deficiencies in AG+/RAS or AG-/RAS patients, respectively.

Anemia and hematinic deficiencies in anti-gastric parietal cell antibody-positive or all autoantibodies-negative recurrent aphthous stomatitis patients.

Approximately 13% of recurrent aphthous stomatitis (RAS) patients have serum anti-gastric parietal cell antibody (GPCA) positivity. This study assessed whether serum GPCA or RAS itself was a significant factor causing hematinic deficiencies and anemia statuses in GPCA-positive RAS (GPCA+/RAS) and all autoantibodies-negative RAS (Abs-/RAS) patients. The mean corpuscular volume (MCV) and mean blood hemoglobin (Hb), iron, vitamin B12, and folic acid levels were measured and compared between any two of three groups of 31 GPCA+/RAS patients, 240 Abs-/RAS patients, and 342 healthy control subjects. GPCA+/RAS patients had significantly lower mean Hb and serum iron level (for women only) as well as significantly greater frequencies of Hb, iron, and vitamin B12 deficiencies than healthy control subjects. Moreover, GPCA+/RAS patients had a significantly higher MCV and a significantly greater frequency of vitamin B12 deficiency than Abs-/RAS patients. Furthermore, Abs-/RAS patients did have significantly lower mean Hb, MCV, iron, and folic acid levels and significantly greater frequencies of Hb, iron, vitamin B12, and folic acid deficiencies than healthy control subjects. Of 31 GPCA+/RAS patients, 3 (9.7%) had PA, 6 (19.4%) had vitamin B12 deficiency, and 3 (9.7%) had macrocytosis. Moreover, normocytic anemia (54.0%) and iron deficiency anemia (26.4%) are the two more common types of anemia in our RAS patients. We conclude that serum GPCA plays a significant role in causing vitamin B12 deficiency and high MCV in GPCA+/RAS patients. RAS itself does play a significant role in causing anemia and hematinic deficiencies in both GPCA+/RAS and Abs-/RAS patients.

Anemia and hematinic deficiencies in anti-gastric parietal cell antibody-positive and -negative recurrent aphthous stomatitis patients with anti-thyroid antibody positivity.

Serum anti-gastric parietal cell (GPCA), anti-thyroglobulin (TGA), and anti-thyroid microsomal antibodies (TMA) can be found in some recurrent aphthous stomatitis (RAS) patients. This study mainly assessed whether serum GPCA, TGA, TMA and RAS itself played significant roles in causing anemia and hematinic deficiencies in TGA/TMA-positive RAS patients with GPCA positivity (GPCA+/TGA/TMA/RAS patients) or negativity (GPCA-/TGA/TMA/RAS patients). The mean corpuscular volume (MCV) and mean blood hemoglobin (Hb), iron, vitamin B12, and folic acid levels were measured and compared between any two of the four groups of 15 GPCA+/TGA/TMA/RAS patients, 69 GPCA-/TGA/TMA/RAS patients, 240 all autoantibodies-negative RAS patients (Abs-/RAS patients), and 342 healthy control subjects. GPCA+/TGA/TMA/RAS patients had significantly lower mean Hb (for men only) and vitamin B12 levels as well as significantly greater frequencies of Hb, iron, and vitamin B12 deficiencies than healthy control subjects. GPCA+/TGA/TMA/RAS patients had lower serum vitamin B12 level and higher MCV as well as a significantly greater frequency of vitamin B12 deficiency than GPCA-/TGA/TMA/RAS patients. Furthermore, both GPCA-/TGA/TMA/RAS and Abs-/RAS patients did have significantly lower mean Hb, MCV, and iron levels as well as significantly greater frequencies of Hb, iron and vitamin B12 deficiencies than healthy control subjects. There were no significant differences in blood data between GPCA-/TGA/TMA/RAS and Abs-/RAS patients CONCLUSION: Both serum GPCA positivity and RAS itself are the contributing factors causing anemia and hematinic deficiencies in GPCA+/TGA/TMA/RAS patients. RAS itself but not TGA/TMA positivity plays a significant role in causing anemia and hematinic deficiencies in GPCA-/TGA/TMA/RAS patients.
