Background: Preeclampsia is considered as a serious life-threatening condition that could affect both maternal and fetal outcome. Many studies have examined the association of nutritional factors with the incidence of preeclampsia. However, little is known about the possible role of vitamin D in the development of preeclampsia among the Iranian population. Objective: The aim of the present study was to evaluate the association between vitamin D status and preeclampsia. Materials and Methods: A total of 120 pregnant women who were referred to Kamali and Alborz General Hospital located in the Karaj City were enrolled in this study and categorized into preeclamptic and control groups (n = 60/each). The clinical details of patients such as demographic characteristics and laboratory findings were obtained from the patients. The serum levels of vitamin D, calcium, phosphorus, and parathormone were also measured. Multivariate logistic regression analysis was used to assess for independent predictors of preeclampsia. Results: The mean age among pregnant women with preeclampsia and control group were 31.48 ± 5.25 and 29.01 ± 5.28, respectively. The mean body mass index among the preeclamptic group was 27.92 ± 4.98, which was significantly higher compared to the control group (p < 0.001). The serum vitamin D levels were significantly lower in women with preeclampsia compared to the control subjects (p = 0.007). Moreover, no correlation between vitamin D deficiency and predisposing factors of preeclampsia was observed after adjusting for confounding factors. Conclusion: Our study revealed that serum vitamin D level is significantly lower in among the pregnant women diagnosed with preeclampsia compared to the healthy subjects. However, no correlation was observed between the vitamin D status and the risk of preeclampsia development. Key words: Preeclampsia, Vitamin D, 25-Hydroxyvitamin D, Pregnancy.

Background: This study was done to evaluate the association of serum vitamin D level with GDM (n=30) and without GDM (n=30). The age and body mass index of the participants along with their gestational age, gravidity and parity were harmonized. The serum vitamin D levels and blood glucose were investigated. The results revealed that, normal pregnant women had significantly higher vitamin D level than their GDM counterparts.Methods: This case-control study was conducted on healthy pregnant women attending routine antenatal care at Bangabandhu Sheikh Mujib medical university from January 2019 to December 2019 recruited at third trimester of gestation. We measured maternal serum vitamin D status (25[OH]D) in third trimester of pregnancy. GDM was diagnosed according to the American diabetes association. guidelines. Vitamin D status was defined as, vitamin D sufficiency (≥30 or ≥75 nmol/L), insufficiency (20-30 and 50-75 nmol/L), were used to categories participants according to their 25[OH]D concentrations. We calculated adjusted odds ratios and 95% confidence intervals (CIs) using logistic regression.Results: The mean serum vitamin D level was lower in case group case 23.4 (17.4±35.1) compared to that in control group 29.7 (15.4±39.8) and the difference between the 2 groups was statistically significant (p≤0.001). Sufficient level of vitamin D was more in control group (66.7%) than that of case group (26.1%). Insufficient level of vitamin D was higher in case (73.3%) group than that of control (33.3%) group. These findings were significant (p=0.021). Respondents with insufficient level of vitamin D have 3.1 times more chance to develop GDM.Conclusions: Serum vitamin D level is reduced in pregnant women having GDM.

Objective: To investigate whether serum vitamin D levels have an effect on pseudoexfoliation (PEX) glaucoma/syndrome development and on the control of glaucoma in these cases. </P><P> Method: A total of 31 cases with PEX glaucoma, 34 cases with the PEX syndrome and 43 control subjects of similar age and sex were included in the study. Vitamin D levels were compared between the groups and also between the cases where glaucoma surgery was performed or not. Results: PEX glaucoma group consisted of 17 males and 14 females, PEX syndrome group of 27 males and 7 females, and the control group of 27 males and 16 females. The mean age was 70.9±8.9 years, 72.1±7.3 years, and 67.9±9.1 years in PEX glaucoma, syndrome and control group, respectively. Mean vitamin D levels were 9.4±7.7 ng/mL, 7.9±6,1 ng/mL, 11.5±14.2 ng/mL in PEX glaucoma, syndrome and control group, respectively (p>0.05). The mean serum vitamin D level was 8.04±4.7 ng/mL in those who underwent glaucoma surgery and 10.1±8.7 ng/mL in those who didn't undergo glaucoma surgery in PEX glaucoma group (p>0.05). No difference was found between the PEX glaucoma subgroups in terms of the mean deviation when classified according to vitamin D levels (<10 ng/mL, ≥10 ng/mL) (p>0.05). Conclusion: Although we found no statistically significant difference between the PEX syndrome/ glaucoma, and control group in terms of serum vitamin D levels, serum vitamin D levels were lower in PEX syndrome and glaucoma group than control group. Our results indicate that serum vitamin D levels have no effect on the development of PEX glaucoma/syndrome or the control of the disorder in cases with PEX glaucoma. However, these results need to be supported with further studies on a larger number of patients and with longer follow-up.

Abstract Several studies have demonstrated that higher levels of vitamin D are associated with better prognosis and outcomes in infectious diseases. We aimed to compare the vitamin D levels of paediatric patients with mild/moderate coronavirus disease 2019 (COVID-19) disease and a healthy control group. We retrospectively reviewed the medical records of patients who were hospitalised at our university hospital with the diagnosis of COVID-19 during the period between 25 May 2020 and 24 December 2020. The mean age of the COVID-19 patients was 10.7 ± 5.5 years (range 1–18 years); 43 (57.3%) COVID-19 patients were male. The mean serum vitamin D level was significantly lower in the COVID-19 group than the control group (21.5 ± 10.0 vs. 28.0 ± 11.0 IU, P < 0.001). The proportion of patients with vitamin D deficiency was significantly higher in the COVID-19 group than the control group (44% vs. 17.5%, P < 0.001). Patients with low vitamin D levels were older than the patients with normal vitamin D levels (11.6 ± 4.9 vs. 6.2 ± 1.8 years, P = 0.016). There was a significant male preponderance in the normal vitamin D group compared with the low vitamin D group (91.7% vs. 50.8%, P = 0.03). C-reactive protein level was higher in the low vitamin D group, although the difference did not reach statistical significance (9.6 ± 2.2 vs. 4.5 ± 1.6 mg/l, P = 0.074). Our study provides an insight into the relationship between vitamin D deficiency and COVID-19 for future studies. Empiric intervention with vitamin D can be justified by low serum vitamin D levels.

Abstract Objective To investigate the relationship between otitis media with effusion (OME) and serum vitamin D level in children. Methods This prospective case control study was conducted at Ain Shams University Hospitals between February 2018 and May 2019. The study population included 50 children with OME confirmed by tympanometry type (B) who will undergo adenotonsillectomy and grommet tube insertion compared to 50 children without OME confirmed by tympanometry type (A) who will undergo adenotonsillectomy. Measurement of serum 25-hydroxy vitamin D using electrochemiluminescence technique from a blood sample (3cm) taken from them on the day of surgery. Results In this study, the mean age of the cases was 4.24 ± 0.80 and 5.34 ± 1.19 years for the controls besides 23 (46%) of the OME group were boys and 27 (54%) were girls, compared with 29 (58%) boys and 21 (42%) were girls in the control group. The mean levels of vitamin D in children with OME was 16.24 ± 7.14 ng/mL and in children in the control group was 15.89 ± 5.84 ng/mL (P = 0.815) and it was statistically non significant. Conclusion There was no significant relation between vitamin D serum level and the incidence of OME in children.

Low serum vitamin D levels have been associated with various vascular diseases. Very little is known its association with acute stroke in Bangladeshi population. We therefore sought to assess whether low serum 25- hydroxyvitamin D, a marker of vitamin D status is associated with acute stroke. We performed a prospective study in Comilla Medical Collage, Comilla, from November 2016 to November 2017. All the patients diagnosed as acute ischemic stroke on the basis of CT scan or MRI of brain. Patients were eligible for inclusion if they were admitted with onset of symptoms within 24 hours. Estimation of 25(OH)D level was done at presentation. The patients were stratified by vitamin D status, >30 as vitamin D sufficient, vitamin D 20-20.9 as insufficient and finally vitamin D<20 as deficient. Multivariate logistic regression analysis revealed that out of the desired 7 variables, smoking, hypertension and low serum vitamin D were found independent predictors for acute stroke with ORs being 1.44, 4.23 and 2.39 respectively. Vitamin D deficiency represents an important risk factor for acute stroke and it might play a causal role in the development adverse events associated with stroke.Medicine Today 2018 Vol.30(1): 34-37

Background: Recurrent aphthous stomatitis is one of the most prevalent oral mucosa diseases and the etiology is unclear. As a potent anti-inflammatory and immunomodulating agent, vitamin D can significantly affect oral cavity homeostasis. However, to the best of our knowledge, no study has been conducted in pediatric population on the potential role of vitamin D in recurrent aphthous stomatitis to date. The aim of the present study is to determine the vitamin D status in recurrent aphthous stomatitis in children. Methods: This study is conducted retrospectively. Seventy-two patients with minor recurrent aphthous stomatitis and 70 age-matched healthy controls included in the study. 25-Hydroxyvitamin D levels were measured in all patients using enzyme immunoassay. Results: Serum vitamin D levels were 16.4 (8.6) ng/mL in patient group and 23.1 (11.5) ng/mL in healthy controls. There was a statistically significant difference between the groups in terms of serum vitamin D levels ( P = .002). There was no significant correlation between serum vitamin D levels and the severity of the recurrent aphthous stomatitis ( r = 0.54, P = .76). Conclusions: Our study showed a significant difference in vitamin D levels between patients with recurrent aphthous stomatitis and the healthy control group. We also found no correlation between vitamin D status and the severity of the disease.

Background: Transient tachypnea of the newborn (TTN) is one of the most frequent causes of respiratory distress in neonates. A relationship has been shown between vitamin D deficiency and respiratory disorders in neonates. This research was carried out to evaluate the serum level of vitamin D in TTN newborns and their mothers compared to the control group. Methods: This case-control research was conducted during 2016-2019 in a general hospital affiliated with Mashhad University of Medical Sciences, Iran. Thirty-four infants with TTN and 82 neonates in the control group as well as their mothers were investigated. The levels of umbilical cord serum vitamin D in infants with TTN and also their mothers were compared to the control group. Results: The mean levels of serum vitamin D in infants with TTN and their mothers were 8.11 ± 4.32 and 12.6 ± 10.12 ng/mL, respectively (P<0.001), whereas they were 19.21 ± 12.71 and 25.96 ± 16.6 ng/mL in the newborns of the control group and their mothers, respectively (P<0.001). The mean differences (95% CI) of neonatal and maternal vitamin D level between the two groups were 11.10 (7.92–14.28) and 13.36 (7.90–18.08), respectively. In the TTN group, 100% of the infants had vitamin D levels less than 30 ng/mL (79.4% had severe, 17.6% had moderate and 2.9% showed mild deficiency). However, vitamin D levels lower than 30 ng/mL were observed in 76.4% of the neonates in the control group (28.8% had severe, 31.1% showed moderate and 16.3% had a mild deficiency) (P<0.001). Conclusion: The serum vitamin D levels of infants with TTN and their mothers were significantly lower than the control group. Therefore, TTN in infants may be reduced through the treatment of vitamin D deficiency in mothers.

Abstract Background Preeclampsia is a pregnancy-specific disorder that affects 3–5% of pregnant women worldwide and is one of the most frequently encountered medical complications of pregnancy. Recent research has pointed towards some role of vitamin D deficiency in pathogenesis of preeclampsia. Vitamin D deficiency in pregnant women and their children is a major health problem, with potential adverse consequences for overall health. Aim of the Study The aim of this study is to investigate the serum vitamin D levels in preeclampsia and healthy normotensive pregnant women. Patients and Methods This case control study was conducted at Ain Shams University Maternity Hospital from November 2017. The study included pregnant women 20-35years this study will be carried out on pregnant women recruited at pre labour room (preeclamptic group) and (non preeclamptic group) at Ain Shams University Maternity Hospital, 50 women in each group. Results All samples were screened by DRG® 25-OH Vitamin D (total) ELISA (EIA-5396) and it was found that mean 25 hydroxy vitamin D levels were lower in preeclamptic group than normotensive control group. Mean level of 25 hydroxy vitamin D between preeclamptic cases was 13.98 ±4.98 ng/ml and between normotensive controls was15.62± 3.51 ng/ml. Conclusion This study has shown no association between vitamin D deficiency and pre-eclampsia, supporting no role for vitamin D as a preventative agent against preeclampsia.

Background: medication related osteonecrosis of the jaw (MRONJ) is a chronic condition of the oral cavity resulting in mucosal ulceration and exposure of underlying necrotic bone, and the ensuing secondary complications. The aim of this study was to evaluate the relationship between vitamin D deficiency and osteonecrosis of the jaw related to bisphosphonates. Materials and methods: This was a case-control study. The samples were 20 patients taking bisphosphonates, that 10 of them were with MRONJ and 10 were non-MRONJ. Clinical examination of patients was performed to diagnose jaw osteonecrosis. Demographic data of the patients were recorded including age, sex, type of drug, duration and cause of drug intake, and measurement of serum vitamin D levels. Data were analyzed using SPSS software. Results: In the patients without MRONJ, the mean age was 60.60 (±14.975) years, and in the patients with MRONJ, the mean age was 68.30 (69.92) years. As a whole, of the 16 female patients in this study, 10 cases (62.5%) were non- MRONJ and 6 cases (37.5%) were suffered by MRONJ. All of the male patients presented with MRONJ. In control group mean of vitamin D was 63.990 ng/ml (±29.796) and in case group mean of vitamin D was 29.510 ng/ml (±23.723). The serum level of vitamin D (25-OHD) was significantly higher in control group than in the case group (p=0.010). Conclusion: According to our result, there were statistically significant relationship between age, sex, type of drug, vitamin D level, and MRONJ (p>0.05).

Background: Neonatal sepsis is one of the most important causes of an infant’s death, and the identification of its factors has been the subject of many studies. Some new evidence suggested the role of vitamin D in the occurrence of sepsis in infants. Objectives: The aim of this study was to compare the serum levels of vitamin D in neonates with sepsis in the first week of birth and healthy neonates. Methods: This case-control study was performed on 72 term neonates (36 neonates with sepsis as the case and 36 healthy neonates as the control group) who referred to Bandar Abbas children's hospitals, Bandar Abbas, Iran, from 2016 - 2017. Results: Serum vitamin D levels were measured in all infants and their mothers in both sepsis and control groups. In addition, data were collected, including sex, birth weight, C-reactive protein (CRP), and duration of hospitalization in neonates with sepsis. The mean serum level of vitamin D was 18.52 ± 11.49 ng/mL in sepsis and 20.52 ± 13.75 ng/mL in neonates of the control group (P ≥ 0.05). The mean maternal serum level of vitamin D in sepsis control groups was 22.44 ± 11.26 and 24.36 ± 12.82 ng/mL, respectively (P ≥ 0.05). There was a positive correlation between maternal and neonatal vitamin D levels in the sepsis (r = 0.803) and the control (r = 0.756) groups. However, there was no significant difference between vitamin D level and CRP (P = 0.148) and length of hospital stay (P = 0.396) in the sepsis group. Conclusions: Although the results of the present study showed a correlation between serum vitamin D levels in mothers and neonates with neonatal sepsis, there was no significant correlation between neonates with and without sepsis regarding vitamin D levels.
