Beta-thalassemia is a heterogeneous group of hereditary blood disorders characterized by defects in the synthesis of the β- chains of hemoglobin, resulting in variable phenotypes ranging from severe anemia to clinically asymptomatic individuals. This study aims to assess the serum PTH, vitamin D, calcium, phosphorus, alkaline phosphatase, and magnesium levels in β-thalassemia major patients. A total of 50 (30 male and 20 female) patients with β- thalassemia major with ages range 11- 16 years and an equal number of sex-matched healthy adolescents as a control group were included in this study. A total of 52% of patients were lived in an urban area, and there was no significant difference between patients and the control group regarding residency. Male patients showed low statistically significant (P 0.05) mean serum PTH, vitamin D, and calcium levels, but mean serum phosphorus and alkaline phosphatase levels were significantly higher (P 0.05) as compared to the male control group. However, female patients had low, but without statistical significant (P>0.05) mean serum PTH level, whereas vitamin D and calcium levels were highly significant (P 0.05) reduced. The phosphorus and ALP levels were highly significantly (P 0.05) increased as compared to female controls. Regarding β- thalassemia major group, the current study showed male patients had non-significant (P 0.05) higher levels of PTH, calcium, phosphorus, and ALP. In contrast, vitamin D level was non-significantly (P 0.05) low in male patients as compared to female patients. Mean serum level of PTH had a negative correlation with phosphorus, but it had a positive association with vitamin D, calcium, ALP, and magnesium. In conclusion, this study demonstrated that β-thalassemia major patients have a markedly deranged biochemical metabolic bone profile. Regular monitoring of PTH and biochemical mineral profile is also recommended.

Backgrоund. Osteoporosis is an important factor in the pathogenesis of orthopedic manifestations in children with cerebral palsy. It was previously demonstrated that children with cerebral palsy have specific changes in bone metabolism, which can cause changes in laboratory parameters compared with other orthopedic patients without neurological backgrounds. Aim. The aim of this study was to assess bone metabolism biomarkers in children with cerebral palsy, identifying distinguishing characteristic patterns in comparison with patients with orthopedic pathology without neurological backgrounds. Materials and methods. This study evaluated the concentrations of calcium, phosphorus, -cross laps, osteocalcin, vitamin D, CICP, and alkaline phosphatase in the blood serum of 50 children with cerebral palsy aged between 6 to 12 years with GMFCS levels IIII. The control group consisted of 50 patients with plano-valgus deformities of the feet. Results. The alkaline phosphatase activity in the group of children with cerebral palsy was 170.25 59.35 u/L, while in the control group it was 145.58 46.29 u/L; the CICP concentration in the study group was higher than in the control group (324.01 174.10 and 269.68 240.98, respectively). The concentration of -cross laps, osteocalcin, calcium, and vitamin D in the study group was lower than in children with flat feet. Conclusions. This study demonstrated multidirectional changes in the biomarkers of bone metabolism that are characteristic of walking children with cerebral palsy. These changes are characterized by a corresponding increase in the activity of osteoresorption and osteoreparation. This makes it possible to justify the combined use of metabolites and metabolic activators (calcium and vitamin D) and drugs that suppress osteoresorption (bisphosphonates) for the prevention and treatment of osteoporosis in children with cerebral palsy.

Plasma calcium, phosphorus, alkaline phosphatase, total protein, and albumin were measured during pregnancy in a group of Asian women living in the south of England and in a control group. The Asian women had slightly lower mean plasma calcium concentrations than the control group. Exposure of Asian women to sunshine appeared to be low, and it was inferred that they probably had little endogenous synthesis of cholecalciferol as a result. Both Asian and control subjects ingested similarly low amounts of vitamin D. The Asian women consumed greater amounts of phytate and vegetable fibres than the controls, and it is suggested that these substances may reduce absorption of insoluble lipids (including cholecalciferol) and calcium in a setting where the dietary intake and endogenous synthesis of vitamin D are already borderline for the subjects' requirements.

Objective This study aimed to investigate the relationship between autism spectrum disorder (ASD) and vitamin D levels in children and adolescents. Methods We measured serum 25-hydroxyvitamin D (25-OHD) levels in 1529 patients with ASD aged 3 to 18 years, without any additional chronic diseases. Levels of 25-OHD were compared according to sex, age (<11 or ≥11 years), and birth season. Additionally, laboratory parameters (calcium, phosphorus, alkaline phosphatase, and 25-OHD) of 100 selected patients with ASD were compared with those of the healthy control group. Results Vitamin D deficiency or insufficiency was found in approximately 95% of all patients. Levels of 25-OHD in adolescent patients with ASD aged 11 to 18 years were significantly lower than those in patients aged younger than 11 years. In the 100 selected patients with ASD, mean serum 25-OHD levels were significantly lower and alkaline phosphatase levels were higher compared with those in healthy children. Conclusion Our study suggests a relationship between vitamin D and ASD in children. Monitoring vitamin D levels is crucial in autistic children, especially adolescents, to take protective measures and treat this condition early.

β-thalassemia major is severe hemolytic anemia which requires repeated blood transfusion and for survival, which leading to iron overload. Serious complications due to iron over load are recognized in the thalassemia patients. objectives Vitamin D and calcium are important factors for homeostasis of calcium in this study. This study was conducted for a period of two year including from patients with β- thalassemia major from Duhok Thalassemia Centre between 2014 -2015. Thirty eighth β- thalassemia major patients and thirty eighth persons with age- matched as control group were enrolled in the study. Serum concentration of 25- hydroxy vitamin D and calcium were estimated by enzyme linked fluorescent assay and colorimetric method, respectively. In patients, the level of serum 25- hydroxy vitamin D was significantly lower 11.11±4.36 ng/mL compared with control group (14.03±5.96ng/mL). Vitamin D deficiency is observed about 94.73% in patients. The mean level of serum calcium in patients group is 7.9±0.47mg/dL and 8.98±0.77 mg/dL in control group. There was a statistically significant difference in serum calcium value between patients and control group. 44.73% of patients have hypocalcaemia. This study demonstrated a high prevalence of Vitamin D deficiency and low total serum calcium levels in thalassemia patients with a significantly lower than healthy group. Hypocalcemia and vitamin D deficiency may be results from the negative effect of the repeated blood transfusion and malnourishment.

This study aims to assess vitamin D levels in women with postmenopausal osteoporosis and healthy women going through menopause. Two groups of menopausal women took part in the study – 41 women with osteoporosis and 22 without osteoporosis. The levels of vitamin D, parathormone, alkaline phosphatase, calcium and phosphorus were examined during the autumn-winter period. Calcium, phosphorus and alkaline phosphatase were established within the reference range in both groups. A negative correlation with increase of parathormone levels among the patients with osteoporosis and vitamin D deficiency was found (r = -0.46, p<0.01). 16 women with osteoporosis (39%) were with normal levels of vitamin D, 14 (34,1%) were with insufficiency and 11 (26,9%) with deficiency. Within the control group, 8 women (36,4%) were with normal levels of vitamin D, 12 (54,5%) were with insufficiency and 2 (9,1%) with deficiency.

AbstractThe aim of this study was to evaluate the effect of prescribing vitamin D on improving the symptoms of patients diagnosed with urosepsis. The participants were randomly divided into two equal groups (each consisting of 50 patients). The patients in the first group received standard treatment with 300 000 units of injected vitamin with a volume of 1 cc. As for the patients in the second group, they received standard treatment along with 1 cc normal saline injected to them as placebo. Vital signs of the patients were checked every 6 h, while their CBC, EXR, CRP, creatinine, urea, and uric acid were checked 0, 24, 48, and 72 h following the interventions. Calcium, phosphorus, and vitamin D levels were measured 72 h following injection of the medicine. A significant difference was observed between the two groups in terms of the number of WBC’s in 24th, 48th, and 72nd hours. A similarly significant difference was reported between the case and control group in terms of the average BUN within 24th, 48th, and 72nd hours. The difference observed between the two groups in terms of average Cr within the 0th, 24th, 48th, and 72nd hours and in terms of days of hospitalization was also significant. Considering these results and keeping in mind the fact that no particular side effects were reported as a result of utilizing muscular injections of vitamin D and the easy and cheap use of this medicine, it can be used in auxiliary treatment of patients with urosepsis.

Background: In children, vitamin D deficiency can result in the hypertrophy of costochondral junctions and sternal pain. Objectives: In this study, we aimed at determining the correlation between children’s vitamin D status and costochondritis. Methods: This cross-sectional study included a control group (100 healthy children) and a study group (100 children with costochondritis). Examination of patients included chest radiography, physical examination, history-taking, electrocardiography, echocardiography, and serum measurement of 25-hydroxyvitamin D, phosphorus, calcium, and alkaline phosphatase. The Chi-square test, Spearman’s correlation test, and independent samples t-test were also performed for analyzing the data. Results: The groups showed no significant difference regarding age, gender, or body mass index (P = 0.315, P = 0.671, and P = 0.097, respectively). The history of patients experiencing idiopathic chest pain showed cardiac disease in 13% of their families, without report of death in the family. The pain was mainly located in the left precordium (64%), followed by the right precordium and the midsternal region (32% and 18%, respectively). A significantly lower level of 25-OHD was found in the study group than in the control group (P < 0.0001). Based on the findings, the groups were not significantly different regarding the evaluated biochemical parameters, except for alkaline phosphatase (P = 0.007). The results showed that pain duration and episodes were significantly associated with vitamin D insufficiency (r = -0.621, P = 0.002; r = -0.213, P = 0.021, respectively). Conclusions: Vitamin D insufficiency should be considered in costochondritis. Also, pain duration and episodes have associations with vitamin D insufficiency. This finding emphasizes the necessity of evaluating nutritional parameters in children with non-cardiac chest pain.

Background: β-Thalassemia major is a serious hematological problem requiring regular blood transfusions. In regularly transfused thalassemic patients, metabolic bone disease is an important cause of morbidity. Problems include bone pain, deformities, short stature, osteopenia/osteoporosis, rickets, osteomalacia, spinal deformities, nerve compression and fractures. This study was undertaken to evaluate the status of bone health in children with β-thalassemia major by selected biochemical indices and radiological examination.Methods: Fifty children with β- thalassemia major were enrolled. Detailed history, examination and anthropometry were done. Serum calcium, phosphorus, magnesium, alkaline phosphatase, and vitamin D levels were measured. X-ray of skull, wrist, and knee were studied for radiological changes. Biochemical indices were analysed with appropriate statistical tests.Results: Stunting and wasting was observed in 58% and 44% children respectively. Hypocalcaemia was seen in 22%, hyperphosphatemia in 56% and 24% children had raised alkaline phosphatase levels. Vitamin D levels were severely deficient in 12%, deficient in 50%, and insufficient in 38% of children. There was no significant difference between vitamin D levels of cases and controls. Radiologically almost all children had a range of osteopathy, like thinned out cortex (96%), medullary expansion (54%), loss of density (40%), diffuse osteoporosis (18%) and growth arrest lines were seen in 8% children.Conclusions: Vitamin D abnormalities and radiological features suggestive of decreased bone mineralization are seen in all the children with β-thalassemia major treated with periodic blood transfusion at this institute. No biochemical predictors of bone disease in these children were identified.

Abstract Background: We conducted this study to discover changes of serum FGF23 in non-uremic rat model of vitamin D deficiency without secondary hyperparathyroidism using paricalcitol. Methods: 30 adult male rats weighting 300±20 grams were enrolled. They were divided into three groups of 10 rats including Control, Vitamin D deficient(VDD), and Vitamin D deficient diet treated with paricalcitol(VDD+P). Serum biochemical were checked twice, at baseline and after the 22nd day of study. Results: There was no significant difference in baseline laboratory data between groups. At the end of the study, 1,25(OH)D3 was reduced in VDD (P = 0.019) and VDD+P (P < 0.001) with a more significant decline in VDD+P group. Serum level of FGF23 was reduced in VDD+P group compared to the control group (P = 0.011) and VDD group (P = 0.021). serum PTH in VDD group was higher than the control and VDD+P group (P = 0.036 and P = 0.038, respectively). Conclusion: The present study showed that paricalcitol could reduce FGF23 in vitamin D deficient rats without any changes in serum calcium, phosphorous and fractional excretion of phosphorous, which might be due to low PTH and 1,25(OH)2 D3.

AbstractPatients afflicted with melanoma show lower vitamin D serum levels (VDSL) than the healthy population. This hypothesis agrees with its well-known antiproliferative features. An observational study was carried out to collect VDSL in patients suffering from melanoma. Our aim was to identify a potential connection between low VDSL and the risk to incur melanoma. Furthermore, we studied the association between VDSL at the diagnosis of melanoma and other germane prognostic factors. The population held in regard was composed of 154 patients with a diagnosis of melanoma between 2016 and 2019. These patients were retrospectively collected from our follow-up storage. We compared VDSL to clinical and pathological parameters (age, sex, tumour location, Breslow’s depth, Clark’s level, histological subtype, ulceration, et aliqua). Moreover, we recruited a control group with negative melanoma history. Mean and median of VDSL were significantly lower in the melanoma group. Instead, we found a negative association between melanoma and VDSL > 30 ng/L (OR 0.11; p < 0.0001). No correlation between VDSL and both Breslow’s depth and Clark’s level was discovered, but the VDSL comparison between thin (depth ≤ 1 mm) and thick tumours (depth > 1 mm) revealed a statistically significant difference (21.1 ± 8.2 ng/L vs 17.8 ± 8.1; p = 0.01). Moreover, VDSL were significantly lower in melanomas with mitotic rate ≥ 1/mm2 (22.1 ± 8.3 ng/L; p < 0007). Nevertheless, no connection was found between VDSL and both ulceration and positive sentinel nodes (p = 0.76; p = 0.74). Besides, our study revealed no association between VDSL and histological subtype (p = 0.161). Lower VDSL correlate with thick and high mitotic rate tumours. Future prospective studies would investigate if appropriate upkeep of suitable VDSL can decrease the risk of primary and recurrent melanoma diagnosis.
