Abstract
BACKGROUND Biomarkers of oxidative stress (OS) have been poorly explored in fungal peritonitis (FP). Potassium is a regulator of pro-oxidants and antioxidants. Albumin and vitamin B12 (B12) are vital antioxidant agents in the circulatory system. This study aimed to investigate the antioxidative role of serum potassium, albumin and B12 in FP. METHODS Serum levels of potassium, albumin and B12 were retrospectively analyzed in 21 patients with a confirmed diagnosis of FP, 105 bacterial peritonitis (BP) patients and 210 patients receiving peritoneal dialysis without peritonitis. RESULTS Serum levels of potassium, albumin and B12 were lower in FP patients than in BP patients. Serum potassium concentration was statistically related to albumin concentration in peritonitis patients. Univariate and multivariate binary logistic regression analysis suggested that serum level of potassium and albumin were independent risk factors of FP when compared with BP. Lower potassium and B12 levels were independently associated with higher rates of technique failure in peritonitis. CONCLUSION These findings suggest lower serum potassium, albumin and B12 as potential oxidative stress markers of FP and raise the hypothesis that an increased level of OS could contribute to FP.KEY MESSAGESFP remains a serious complication of peritoneal dialysis (PD), with higher morbidity (1-23.8%) and mortality (2-25%), and oxidative stress plays a role in it.Our study suggested serum potassium, albumin and vitamin B12 as potential oxidative stress markers of fungal peritonitis.

J Formos Med Assoc 2021; 121:824-831. [PMID: 34690029 DOI: 10.1016/j.jfma.2021.08.028] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2020] [Revised: 06/29/2020] [Accepted: 08/24/2021] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND/PURPOSE Actually, many individuals have opted for the vegetarian diet. The objective of this study was to evaluate the impact of the vegetarian diet on the oral epithelium through cytopathology. METHODS Oral smears of the tongue and buccal mucosa of 60 adult subjects (30 vegetarians and 30 controls) were collected. Smears were analyzed morphologically and for three morphometric variables: nucleus area (NA), cytoplasm area (CA) and nucleus/cytoplasm ratio. RESULTS Vegetarians were classified as ovolactovegetarian (53.3%), vegans (30%) and strict vegetarians (16.7%). The NA and CA of the epithelial cells of vegetarian individuals were smaller when compared to controls both in the region of the buccal mucosa and tongue. However, there was no statistically significant difference according to the Student's t-test. For the NA/CA ratio, cells in the oral mucosa region were larger for vegetarians compared to controls. For the tongue, both groups had the same value and the Mann-Whitney U test confirmed that there is no difference between the groups for this cytomorphometric variable. RESULTS Vegan individuals had a smaller (but not larger) area of CA when compared to controls for the tongue (vegan = 2604.2 ± 179.2 versus control = 3256.7 ± 463.8 p = 0.013). Most smears showed normal epithelial cells and some individuals had changes of an inflammatory nature, mainly in the tongue. CONCLUSION Despite the small sample size, the results of this study raise the hypothesis that the vegetarian diet (especially the vegan diet) can compromise the thickness of the oral epithelium of the tongue.

Anemia, hematinic deficiencies, hyperhomocysteinemia, and gastric parietal cell antibody positivity in burning mouth syndrome patients with vitamin B12 deficiency. J Dent Sci 2019; 15:34-41. [PMID: 32256998 PMCID: PMC7109486 DOI: 10.1016/j.jds.2019.12.002] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2019] [Indexed: 12/30/2022] Open
Abstract
Background/purpose Our previous study found that 42 of 884 burning mouth syndrome (BMS) patients have vitamin B12 deficiency. This study assessed whether the vitamin B12-deficient BMS (B12D/BMS) patients had significantly higher frequencies of anemia, hematinic deficiencies, hyperhomocysteinemia, and serum gastric parietal cell antibody (GPCA) positivity than healthy control subjects and evaluated whether all B12D/BMS patients had pernicious anemia (PA). Materials and methods The blood hemoglobin (Hb) and serum iron, vitamin B12, folic acid, homocysteine, and GPCA levels in 42 B12D/BMS patients and 442 healthy control subjects were measured and compared. Results We found that 42 B12D/BMS patients had significantly lower mean blood Hb and serum iron and vitamin B12 levels as well as significantly higher mean corpuscular volume (MCV) and mean serum homocysteine level than healthy control subjects (all P-values < 0.05). Moreover, 42 B12D/BMS patients had significantly higher frequencies of macrocytosis (52.4%), blood Hb (61.9%) and serum iron (26.2%) and vitamin B12 (100.0%) deficiencies, hyperhomocysteinemia (83.3%), and serum GPCA positivity (42.9%) than 442 healthy control subjects (all P-values < 0.001). Moreover, of 26 anemic B12D/BMS patients, 15 (57.7%) had PA, 5 (19.2%) had macrocytic anemia other than PA, 4 (15.4%) had normocytic anemia, and 2 (7.7%) had thalassemia trait-induced anemia. Conclusion B12D/BMS patients have significantly higher frequencies of macrocytosis, blood Hb and serum iron and vitamin B12 deficiencies, hyperhomocysteinemia, and serum GPCA positivity than healthy control subjects. Although PA is the most common type of anemia in our B12D/BMS patients, only 15 (35.7%) of 42 B12D/BMS patients have PA.
