Serous Otitis Media

Background: Serous Otitis Media (SOM) is one of the most common diseases of children that can lead to hearing loss and imbalance. Recently, the role of vitamin D has been identified in strengthening and regulating the immune system. Moreover, vitamin D supplementation has been recognized to improve the immune response against upper respiratory infection and pathogen overgrowth. Methods: A cross-sectional study was performed on 89 children aged 1 - 15 years with adenoid hypertrophy who met the inclusion criteria. The serum vitamin D level was compared between the two groups of children with and without SOM. Results: The mean age of the target children was 69.57 ± 25.65 months. The mean serum vitamin D level was 23.86 ± 12.7 in all patients. The mean serum vitamin D level was 24.7 ± 13.1 and 22.9 ± 12.2 in patients with and without SOM (based on tympanometry), respectively, yet the difference was not statistically significant. However, the difference was significant between the two groups of children with the age of < 84 months and > 84 months (P = 0.05). Conclusions: The role of vitamin D was identified in increasing the incidence of SOM in children older than 84 months with adenoid hypertrophy. In older children, the timely diagnosis and treatment of vitamin D deficiency can prevent severe SOM complications, which can save a lot of costs for families and the health system.

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.

Background: Vitamin D has been shown to have immunomodulatory effects, and previous studies have proposed a role of vitamin D deficiency in multiple autoimmune diseases, including psoriasis. Objectives: The aim of this study was to investigate serum vitamin D levels in psoriatic patients and compare them with levels in controls. Methods: This study was carried out in 50 psoriasis patients. Serum vitamin D was measured by enzyme-linked immunosorbent assay. Results: The mean serum vitamin D levels in psoriatic patients and controls were 14.92 ± 6.31 and 12.52 ± 4.54 ng/mL, respectively. The difference was not statistically significant ( P = .06). The prevalence of vitamin D deficiency (<20 ng/mL) was 84.0% in psoriatic patients and 93.0% in controls ( P = .21). Conclusions: Most of the patients with psoriasis had vitamin D deficiency, which may have contributed to the evolution of their psoriasis. However, considering the high prevalence of vitamin D deficiency in Iran, no difference was noted between the psoriatic patients and the controls.

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 Study question Is vitamin D deficiency more prevalent in PCOS patients? Is there a link between vitamin D levels and metabolic status in PCOS subjects? Summary answer An inverse relationship between vitamin D levels and metabolic status was demonstrated and it is thought to be responsible of its pathogenesis. What is known already PCOS is a multifactorial condition, characterised by failure in oogenesis and anovulation. Obesity is a common condition linked to its clinical features and studies have reported inverse associations between BMI and severity of the condition. Furthermore, 67–85% of PCOS patients have vitamin D deficiency. Low levels of vitamin D have been found to be closely related to insulin resistance, obesity, or hyperandrogenism and there is a significant association between serum vitamin D levels and reproductive function. Other factors such as AMH have also been described as possibly involved in the pathophysiology. Study design, size, duration We performed a retrospective, analytical and observational study in the Copenhagen Fertility Center. Patients referred with cycle abnormalities, hirsutism, and infertility were evaluated. A total of 778 women were enrolled consecutively from January 2019 to October 2020. Subjects who had major medical disorders were excluded. We selected those in which vitamin D was measured in the baseline analysis selecting a total of 396 patients. The further analysis has been carried out from 100 randomly selected patients. Participants/materials, setting, methods Blood samples were drawn after overnight fasting. They were all assayed in the same laboratory. Biochemical parameters were analyzed using descriptive statistics. Same parameters were studied after dividing into vitamin D deficiency group or optimal levels using a multiple t-test. Correlation between variables was determined. Graphpad Prism program version 8 was used to perform the calculations. The level of statistical significance was set at P-value &lt; 0.05. Main results and the role of chance A total of 100 subjects fulfilling the inclusion criteria were selected randomly from 396 PCOS women. Serum vitamin D concentrations were highly variable ranging from 16 nmol/L to 175 nmol/L. The prevalence of vitamin D deficiency was 24% and 41% of the subjects were classified as vitamin D insufficient. Only 35% of our patients had optimal vitamin D values. We compared data between the group with optimal values of vitamin D (Group A) versus the group with insufficient/deficient vitamin D values (Group B). We found statistical difference between groups in PTH values, being notably higher in group B compared with group A. Despite no statistically significant difference was obtained, it is important to highlight that the mean of SHBG was lower in group B and the mean of androstenedione, AMH, FAI and HOMA-IR were much higher in this group as well. Following the HOMA-IR criteria, 55% of patients had insulin resistance. Specifically, 26% had moderate insulin resistance and 29% severe insulin resistance. Levels of vitamin D were negatively correlated with FAI, AMH and HOMA-IR and positively correlated with HDL-Cholesterol and SHBG. Statistically significant differences were evidenced in the correlation between vitamin D and FAI and SHBG. Limitations, reasons for caution This is a retrospective observational study on a consecutive admitted patient group with a lack of a control group. Another limitation is the small sample size. It is difficult to generalize with other degrees of severity. We didn’t assess seasonal variability or if they were taking any vitamin D supplementation. Wider implications of the findings: Properly randomized clinical trials are mandatory to achieve more conclusive results about the role of vitamin D. Available evidence is promising but not sufficient to draw final conclusions. The aim is to better understand the pathophysiology of the condition and the factors involved and to find new target treatments. Trial registration number 1

While vitamin D insufficiency is known to impact a multitude of health outcomes, including HIV-1, little is known about the role of vitamin D-mediated immune regulation in the female reproductive tract (FRT). We performed a pilot clinical study of 20 women with circulating 25(OH)D levels <62.5 nmol/L. Participants were randomized into either weekly or daily high-dose oral vitamin D supplementation groups. In addition to serum vitamin D levels, genital mucosal endpoints, including soluble mediators, immune cell populations, gene expression, and ex vivo HIV-1 infection, were assessed. While systemic vitamin D levels showed a significant increase following supplementation, these changes translated into modest effects on the cervicovaginal factors studied. Paradoxically, post-supplementation vitamin D levels were decreased in cervicovaginal fluids. Given the strong correlation between vitamin D status and HIV-1 infection and the widespread nature of vitamin D deficiency, further understanding of the role of vitamin D immunoregulation in the female reproductive tract is important.

Background: Low vitamin D levels along with high-intensity athletic training may put an athlete at increased risk for a stress fracture. Purpose: To assess whether supplementation with vitamin D is associated with a reduced risk of stress fractures in college athletes. We also assessed differences in vitamin D levels among athletes participating in outdoor versus indoor sports. Study Design: Cohort study; Level of evidence, 2. Methods: The study participants included 802 National Collegiate Athletic Association Division I intercollegiate athletes (497 men and 305 women) on a sports team for at least 1 semester from 2012 to 2018. All athletes who had a baseline vitamin D level in their medical record were included. Athletes with vitamin D levels <40 ng/mL were given vitamin D supplements. We assessed differences in the rate of stress fracture among those who maintained or improved vitamin D levels to ≥40 ng/mL and those who did not, as well as differences in average baseline vitamin D levels by sport type (indoor vs outdoor). Results: The rate of stress fracture was 12% higher (95% CI, 6-19; P < .001) for those who remained low in vitamin D compared with those who were low at baseline but improved their vitamin D status to ≥40 ng/mL. The rate of stress fracture was also 12% higher (95% CI, 5-18; P < .001) for those who had low vitamin D levels compared with those who maintained normal levels. The mean baseline vitamin D values were significantly higher for men participating in outdoor sports versus indoor sports. For men, the mean vitamin D level was 5.7 ng/mL higher (95% CI, 0.9-10.5; P = .01) in outdoor athletes. For women, the mean vitamin D level was 3.7 ng/mL higher (95% CI, –0.58 to 8.03; P < .04) for outdoor versus indoor sports. Conclusion: Study results indicated that correcting low serum vitamin D levels reduces the risk of stress fracture. This study also presented evidence that athletes who participate in indoor sports may be at greater risk for vitamin D deficiency than those who compete in outdoor sports.

The global crisis caused by the SARS Corona virus-2 infection is continuing through 2021, with more than 3.5 million deaths. Several risk factors for this virus’s severity and death were documented, including diabetes, hypertension, and ischemic heart disease. To evaluate the relation between serum vitamin D3 level, the disease severity, and prognosis of the patients with SARS Corona virus-2 infection. Patients with COVID-19 were evaluated for serum vitamin D levels and laboratory data. Correlation between vitamin D levels and laboratory data with disease severity and prognosis was assessed. Cox and logistic regression tests, as well as ROC curves, were used for data analysis. Ninety-eight patients with Corona virus-2 disease (COVID-19), which consisted of sixty patients with moderate COVID-19 in the general wards, and thirty-eight patients with severe COVID-19 in the intensive care unit (ICU), were evaluated. The mean age in the general wards was lower than in ICU (60.96±14.86 compared to 67.94±16.46, P=0.001), and the mean serum vitamin D level in the patients admitted in the general wards was higher than in the ICU (31 ng/mL compared to 20.57 ng/mL, P=0.003). Furthermore, vitamin D deficiency (25 (OH) D <25 ng/ml) significantly increased the risk of severe disease. (odds ratio=2.91, P=0.019) and mortality (odds ratio=3.64, P=0.026). Vitamin D deficiency is a risk factor for disease severity and poor prognosis in COVID-19. Vitamin D levels of 25 ng/mL can be used as a cut-off value for predicting severity and prognosis.

Background: Allergic rhinitis (AR) is the commonest type of non-infective rhinitis. Genetic and environmental factors play an important role in the development of the disease. Researchers are having interest in knowing the role of vitamin D in the pathogenesis of allergy. Immunoglobulin E (IgE) is integral to the pathogenesis of allergic disorders. However, the relationship between serum IgE levels and AR is still a matter of debate. Thus, this study aimed to know serum IgE and serum 25 (OH) vitamin D levels in patients with clinically diagnosed AR and control group.Methods: A case-control study was performed from May 2019 to October 2019 in LNMC and JK hospital. All 54 children with physician diagnosed AR aged 12 to 18 years of both genders who have come in the OPD (total enumeration sampling) during the above mentioned period were enrolled into the study and their 54 healthy counterparts are taken as controls. Other parameters such as age, gender, occupation and region of residence were also compared between the groups.Results: This study found highly significant difference in the mean serum IgE levels while there is a significant difference in the mean serum vitamin D levels between two groups.Conclusions: The study group with AR had significantly higher mean level of serum IgE and lower mean serum vitamin D levels as compared to control groups. However, upon stratification of vitamin D levels, the differences were insignificant. Further studies should be conducted to know the value of IgE as a prognostic factor of AR severity and to throw more light on association of vitamin D with AR.
