Escobedo-Monge MF, Marcos-Temprano M, Parodi-Román J, Escobedo-Monge MA, Alonso-Vicente C, Torres-Hinojal MC, Marugán-Miguelsanz JM. Calcium, Phosphorus, and Vitamin D Levels in a Series of Cystic Fibrosis Patients: A Cross-Sectional Study. Int J Mol Sci 2024; 25:1900. [PMID: 38339178 PMCID: PMC10856093 DOI: 10.3390/ijms25031900] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 01/03/2024] [Accepted: 01/27/2024] [Indexed: 02/12/2024] Open
Abstract
Cystic fibrosis (CF) is a monogenic disease with different types of mutations that mainly affect the respiratory-digestive system. Calcium (Ca), phosphorus (P), and vitamin D (Vit-D) are essential nutrients for maintaining adequate growth and development, as well as key components in crucial metabolic pathways. Proper diagnosis, treatment, and response are decisive components of precision medicine. Therefore, we conducted a cross-sectional study to evaluate Ca, P, and Vit-D levels along with health and nutritional indicators, regarding their non-skeletal functions, in a series of CF patients. Anthropometric and clinical evaluation, biochemical analysis, dietary survey, and respiratory and pancreatic status were performed. Even though the results showed that all patients had normal dietary and serum Ca levels, 47% of patients had deficient Vit-D intake, 53% of patients had hypovitaminosis D, 35% had insufficient Vit-D levels, 18% had hypophosphatemia, 76% had elevated alkaline phosphate levels, 29% had hypercalciuria, and 65% had hyperphosphaturia. There were no significant differences between homozygous and compound heterozygous patients. Ca, P, and Vit-D levels were associated with body mass index; body composition; physical activity; diet; growth hormones; and the immune, liver, and kidney systems. We suggest a periodically evaluation of Ca and P losses.

Association between vitamin D status and eryptosis-results from the German National Cohort Study. Ann Hematol 2023; 102:1351-1361.

Abstract
Vitamin D, besides its classical effect on mineral homeostasis and bone remodeling, can also modulate apoptosis. A special form of apoptosis termed eryptosis appears in erythrocytes. Eryptosis is characterized by cell shrinkage, membrane blebbing, and cell membrane phospholipid disorganization and associated with diseases such as sepsis, malaria or iron deficiency, and impaired microcirculation. To our knowledge, this is the first study that linked vitamin D with eryptosis in humans. This exploratory cross-sectional trial investigated the association between the vitamin D status assessed by the concentration of plasma 25-hydroxyvitamin D (25(OH)D) and eryptosis. Plasma 25(OH)D was analyzed by LC-MS/MS, and eryptosis was estimated from annexin V-FITC-binding erythrocytes by FACS analysis in 2074 blood samples from participants of the German National Cohort Study. We observed a weak but clear correlation between low vitamin D status and increased eryptosis (r = - 0.15; 95% CI [- 0.19, - 0.10]). There were no differences in plasma concentrations of 25(OH)D and eryptosis between male and female subjects. This finding raises questions of the importance of vitamin D status for eryptosis in terms of increased risk for anemia or cardiovascular events.

Abstract
The expression of Hemoglobin (Hb) is not restricted to erythrocytes but is also present in neurons. Hb is selectively enriched in vulnerable mesencephalic dopaminergic neurons of Parkinson's disease (PD) instead of resistant neurons. Controversial results of neuronal Hb levels have been reported in postmortem brains of PD patients: although neuronal Hb levels may decline in PD patients, elderly men with higher Hb levels have an increased risk of developing PD. α-synuclein, a key protein involved in PD pathology, interacts directly with Hb protein and forms complexes in erythrocytes and brains of monkeys and humans. These complexes increase in erythrocytes and striatal cytoplasm, while they decrease in striatal mitochondria with aging. Besides, the colocalization of serine 129-phosphorylated (Pser129) α-synuclein and Hb β chains have been found in the brains of PD patients. Several underlying molecular mechanisms involving mitochondrial homeostasis, α-synuclein accumulation, iron metabolism, and hormone-regulated signaling pathways have been investigated to assess the relationship between neuronal Hb and PD development. The formation of fibrils with neuronal Hb in various neurodegenerative diseases may indicate a common fibrillization pathway and a widespread target that could be applied in neurodegeneration therapy.

Is There An Association Between Vitamin B12 Level and Vitamin D Status in Children? J Pediatr Hematol Oncol 2022; 44:e677-e681. [PMID: 35319507 DOI: 10.1097/mph.0000000000002329] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2021] [Accepted: 08/16/2021] [Indexed: 11/26/2022]
Abstract
Vitamin B12 (vit B12) or cobalamin is a water-soluble vitamin that acts as a coenzyme and is effective in the formation of a healthy nervous system and erythrocytes. In its deficiency, except fatigue and weakness, may cause serious signs and symptoms such as macrocytic anemia, cognitive-developmental delay, irreversible neurological damage. In this study, hemoglobin, leukocyte, thrombocyte, iron, iron-binding, ferritin, and vit B12 levels were evaluated retrospectively during the routine controls of 689 children 5 to 18 years old without any complaints. In addition, the relationship between serum 25-Hydroxyvitamin D (vit D) levels and vit B12 levels, which were evaluated in 487 of the cases, was investigated. Vit B12 deficiency was diagnosed in a total of 160 (23.2%) cases, 99 (24.4%) girls and 61 (21.4%) boys. Vit B12 level was significantly lower in children over 12 years old. Vitamin D deficiency was found to be 49.3% in 487 cases and was significantly higher in the group under 12 years and girls. The frequency of anemia was 7.2% in this group. There was a significant relationship between vit D deficiency and vit B12 deficiency. In conclusion, vit B12 deficiency is common in school-age children, especially in the adolescent age group. It should be known that vit D deficiency may also be present in vit B12 deficiency cases. More comprehensive studies are needed to reveal the relationship between B12 and vit D deficiency.

Abstract
Vitamin D regulates the master iron hormone hepcidin, and iron in turn alters vitamin D metabolism. Although vitamin D and iron deficiency are highly prevalent globally, little is known about their interactions in Africa. To evaluate associations between vitamin D and iron status we measured markers of iron status, inflammation, malaria parasitemia, and 25-hydroxyvitamin D (25(OH)D) concentrations in 4509 children aged 0.3 months to 8 years living in Kenya, Uganda, Burkina Faso, The Gambia, and South Africa. Prevalence of iron deficiency was 35.1%, and prevalence of vitamin D deficiency was 0.6% and 7.8% as defined by 25(OH)D concentrations of <30 nmol/L and <50 nmol/L, respectively. Children with 25(OH)D concentrations of <50 nmol/L had a 98% increased risk of iron deficiency (OR 1.98 [95% CI 1.52, 2.58]) compared to those with 25(OH)D concentrations >75 nmol/L. 25(OH)D concentrations variably influenced individual markers of iron status. Inflammation interacted with 25(OH)D concentrations to predict ferritin levels. The link between vitamin D and iron status should be considered in strategies to manage these nutrient deficiencies in African children.

Abstract
Background: Research of late has brought to light a connect between Vitamin D and anemia. The level of 25hydroxyvitamin D (25(OH) D) is decreased in periodontitis subjects as against subjects without periodontitis and this reduced level could be related to more risk for anemia in periodontitis patients. Objective: This study aimed to evaluate the serum 25(OH) D levels and red blood cell indices in patients affected by generalized Stage III Grade B periodontitis and healthy controls and to assess the association between level of Vitamin D and red cell indices in periodontitis patients. Materials and Methods: The subjects were categorized into (i) case and (ii) control group of 30 each. Clinical parameters including oral hygiene index simplified, mean ratio of sites that bled on probing, gingival index, probing pocket depth, and the clinical attachment loss were assessed in both the groups. Subjects' blood samples (venous) were taken for the biochemical analysis. Results: In contradiction to healthy subjects, periodontitis subjects had significantly diminished 25(OH) D levels, hemoglobin (Hb), hematocrit, and mean corpuscular hemoglobin concentration (MCHC). 25(OH) D was moderately correlated with MCHC (r = 0.53) and it was statistically significant (P = 0.002). Conclusion: Periodontitis impacts Vitamin D status which further causes anemia. It suggests that effective management of periodontitis can help maintain sufficient Vitamin D status and may be vital in preventing anemia.

Abstract
BACKGROUND This study aims to compare the haematological parameters of patients with very high and normal 25-hydroxyvitamin-D3 (25(OH)D3) levels. METHODS This study was designed as a retrospective cross-sectional study. The patients were divided into three groups according to their 25(OH)D3 levels: groups 1, 2 and 3 are patients with normal 25(OH)D3 levels (30-88 ng/mL), hypervitaminosis D (89-149 ng/mL) and vitamin D intoxication (>150 ng/mL), respectively. According to vitamin D levels, statistical analysis was performed by comparing the biochemical and haematological data between the groups. RESULTS This study evaluated 120 patients (40 patients) in three equal groups. A statistically significant difference was found between the three groups in haemoglobin (p = 0.03), haematocrit (p = 0.01), red blood cell levels (p = 0.03), leukocyte count (p < 0.001), neutrophil count (p < 0.001), lymphocyte count (p = 0.006), mean platelet volume (p = 0.04), and neutrophil/lymphocyte ratio (p = 0.03). In post hoc analysis, haemoglobin, haematocrit and RBC were significantly higher in group 1 than in group 3 (post hoc Tukey, p < 0.05). A statistically significant negative correlation was noted between 25(OH)D3 level and haemoglobin (r = -0.236), haemotocrit (r = -0.230), and red blood cell (r = -0.265) levels. CONCLUSIONS Vitamin D intoxication has been observed to affect haemoglobin, haematocrit, and RBC levels negatively. However, more studies are needed to clarify the effects and mechanisms of high vitamin D levels on the haematopoietic system.

Abstract
BACKGROUND Vitamin D has been shown to be associated with reduced risk and severity of COVID-19 and exerts regulating effects on all hallmarks of cancer. The goal of this study was to analyze the vitamin D status of a cancer patient cohort from our clinic in the Franconian region, Germany. METHODS 25-hydroxyvitamin D concentrations were available for 116 patients included in prospective trials in our clinic. Associations of vitamin D with anthropometric and blood parameters were investigated using Kendall's τ correlation coefficients and linear regression. RESULTS A total of 57 patients (49.1%) were vitamin D deficient (<20 ng/mL), and 92.2% did not meet the recommended vitamin D level of 40 ng/mL. There was a strong negative association between vitamin D and leukocyte count (τ = -0.173, p = 0.007) and C-reactive protein concentration (τ = -0.172, p = 0.007). In linear regression, the most important variables for predicting vitamin D levels were (in order of decreasing importance) season, fat mass index, platelet, and leukocyte count. CONCLUSIONS Despite appeals towards medical societies to target widespread vitamin D deficiency in Germany more than 10 years ago, our data indicate that these have been without avail. Low vitamin D levels in cancer patients should be corrected using reasonable sun exposure and supplements.

Abstract
Iron deficiency anaemia continues to be the world's most important cause of years lived with disability in children and adolescents. Assessment of iron deficiency traditionally depended on laboratory parameters that may be modified by inflammation states, including obesity, which is nowadays a current condition in adolescent population of high-income countries. The present study ascertains the prevalence of iron deficiency and its related factors in adolescents, using the serum transferrin receptor and the reticulocyte haemoglobin content, in order to avoid this confusing effect of classical parameters. A cross-sectional study was conducted on a population-based representative sample for teenagers in Almería (Spain), of 405 subjects aged 12 to 16 years. Iron deficiency was present in 13.3% of adolescents, but iron deficiency anaemia only in 1.2%. Multivariate logistic regression analyses showed that being part of an immigrant family, a low iron bioavailability diet, meat consumption below four times a week and fish consumption below twice a week, were independent risk factors for iron deficiency.Conclusion: This study provides an estimate iron deficiency prevalence of 13.3% in Spanish healthy adolescents, avoiding potential confounding factors through the use of new iron status parameters, based on a wide representative sample of adolescents from the city of Almería. What is Known: • For children and adolescents, iron deficiency anaemia continues to be the world's most important cause of years lived with disability. • Assessment of iron deficiency has traditionally depended on laboratory parameters that may be modified by inflammatory states, including obesity. What is New: • Iron deficiency prevalence and their related factors were analysed in Spanish adolescents, avoiding potential confounding factors through the use of sTfR and CHr. • Being part of an immigrant family and consuming a low iron bioavailability diet are independent risk factors for iron deficiency.

Abstract
Fatigue is characterized by reduced energy level, decreased muscle strength, and a variable degree of cognitive impairment. Recent evidences seem to link vitamin D deficiency to fatigue. The aim of this study was to assess and compare vitamin D status in a cohort of older subjects with and without fatigue. We recruited a total of 480 subjects, 240 patients with fatigue and 240 controls without fatigue, from the Cannizzaro Hospital of Catania (Italy). Fatigue severity was measured by the fatigue severity scale, whereas mental and physical fatigue were measured through the Wessely and Powell fatigue scale, respectively. We also measured several blood parameters and 25-OH vitamin D. Subjects with fatigue showed lower levels of vitamin D as compared with those without fatigue. Blood levels of parameters related to fatigue were normal in both groups of subjects, however, platelet, hemoglobin, hematocrit (p < 0.05), mean corpuscular volume, C-reactive protein (CRP), iron, vitamin B12, and folic acid (p < 0.001) were significantly higher in the fatigue group with respect to the control group. Moreover, compared to controls, patients showed higher scores in the physical (p < 0.001), mental (p < 0.001), and severity (p < 0.001) fatigue scales. Finally, vitamin D inversely correlated with fatigue severity (r = -0.428, p < 0.01), whereas creatine kinase and CRP levels did not correlate with vitamin D. In conclusion, our data showed a direct link between vitamin D and fatigue in older subjects, suggesting translational implications in the diagnosis and management of these patients.

Abstract
OBJECTIVE Both vitamin D and Fe micronutrient deficiencies are common in Saudi Arabia but the association between them is unclear. The present study aimed to determine whether Fe indices are associated with vitamin D status and other metabolic markers in Arab adolescents. DESIGN Single-centre, cross-sectional study gathering anthropometrics, glucose and lipid profile. Serum 25-hydroxyvitamin D (25(OH)D), Fe, total iron-binding capacity (TIBC), transferrin saturation (%) and other parameters were measured. SETTING Vitamin D School Project Database, King Saud University (2014-2016). PARTICIPANTS Arab adolescents aged 10-17 years randomly selected from the Vitamin D School Project Database (170 Saudi students; 100 girls, seventy boys). RESULTS Among Fe indices, only TIBC was found to be significantly and inversely associated with 25(OH)D (r = -0·20; P < 0·01) and only in girls (r = -0·20; P < 0·05). Among cardiometabolic parameters, serum Fe was associated with TAG in boys (r = 0·36; P < 0·01) and inversely associated with HDL-cholesterol in girls (r = -0·29; P < 0·05). Age was the most significant predictor of serum Fe for all participants, accounting for 5 % (R2 = 0·05; P = 0·004) of variance perceived. Serum 25(OH)D and age, on the other hand, were the most significant predictors for TIBC, accounting for 10·1 % (R2 = 0·10; P < 0·001) of variance perceived. CONCLUSIONS Among healthy Arab adolescents, the association between vitamin D and Fe indices, particularly TIBC, is modest, inverse and sex-dependent. Larger studies with inclusion of markers such as hepcidin and ferritin, vitamin D metabolites and endogenous sex hormones may provide a clearer view of this complex association.

Association of first trimester maternal vitamin D, ferritin and hemoglobin level with third trimester fetal biometry: result from cohort study on vitamin D status and its impact during pregnancy and childhood in Indonesia. BMC Pregnancy Childbirth 2019; 19:112. [PMID: 30940099 PMCID: PMC6446282 DOI: 10.1186/s12884-019-2263-1] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2018] [Accepted: 03/26/2019] [Indexed: 12/14/2022] Open
Abstract
Introduction The role of vitamin D in placental functions and fetal growth had been addressed in many reports with conflicting results. However, such report is limited for Indonesian population. The aim of this study was to explore the association between maternal vitamin D level in the first trimester and fetal biometry in the later stage of pregnancy with adjusted OR for other determinants like hemoglobin and ferritin level. Methods From July 2016 a prospective cohort study of pregnant women had begun in four cities in West Java, Indonesia. Data on maternal vitamin D, ferritin, hemoglobin level, maternal demography and fetal biometry were analyzed with linear regression. Results Among 203 recruited women, 195 (96.06%) had hypovitaminosis D. One hundred fifty two (75%) were in deficient state and 43 women (21%) were in insufficient state. Women with insufficient vitamin D had the highest proportion of anemia, while women with normal vitamin D level had the highest proportion of low ferritin level. Maternal serum vitamin D showed significant associations with biparietal diameter (β = 0.141, p = 0.042) and abdominal circumference (β = 0.819, p = 0.001) after adjustment with maternal age, pre-pregnancy body mass index, parity, serum ferritin level, and hemoglobin level. Conclusion Our study suggested that sufficient maternal vitamin D level was an important factor to improve fetal growth and development.

Vitamin D Supplementation Modestly Reduces Serum Iron Indices of Healthy Arab Adolescents. Nutrients 2018; 10:nu10121870. [PMID: 30513812 PMCID: PMC6315440 DOI: 10.3390/nu10121870] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2018] [Revised: 11/21/2018] [Accepted: 11/27/2018] [Indexed: 01/17/2023] Open
Abstract
Vitamin D deficiency has been shown to affect iron status via decreased calcitriol production, translating to decreased erythropoiesis. The present study aimed to determine for the first time whether vitamin D supplementation can affect iron levels among Arab adolescents. A total of 125 out of the initial 200 Saudi adolescents with vitamin D deficiency (serum 25(OH)D < 50 nmol/L) were selected from the Vitamin D-School Project of King Saud University in Riyadh, Saudi Arabia. Cluster randomization was done in schools, and students received either vitamin D tablets (1000 IU/day) (N = 53, mean age 14.1 ± 1.0 years) or vitamin D-fortified milk (40IU/200mL) (N = 72, mean age 14.8 ± 1.4 years). Both groups received nutritional counseling. Anthropometrics, glucose, lipids, iron indices, and 25(OH)D were measured at baseline and after six months. Within group analysis showed that post-intervention, serum 25(OH)D significantly increased by as much as 50%, and a parallel decrease of −42% (p-values <0.001 and 0.002, respectively) was observed in serum iron in the tablet group. These changes were not observed in the control group. Between-group analysis showed a clinically significant increase in serum 25(OH)D (p = 0.001) and decrease in iron (p < 0.001) in the tablet group. The present findings suggest a possible inhibitory role of vitamin D supplementation in the iron indices of healthy adolescents whose 25(OH)D levels are sub-optimal but not severely deficient, implying that the causal relationship between both micronutrients may be dependent on the severity of deficiency, type of iron disorder, and other vascular conditions that are known to affect hematologic indices. Well-designed, randomized trials are needed to confirm the present findings.
