Prevalence of suboptimal vitamin D status in young, adult and elderly Irish subjects

With the exception of the elderly, there is a dearth of information about the vitamin D status of Irish subjects. Therefore, we assessed the prevalence of suboptimal vitamin D status in a number of age-groups within the Irish population (including females aged, 11-13 years, 23-50 years, 51-69 years, and 70-75 years; and males, aged 20-64 years) during late-winter and late-summer. In females, depending on the age-group studied, between 4 and 19% and between 34 and 85% had an inadequate serum 25 (OH) D level (<50 nmol/l) during late-summer and late-winter, respectively. During late-summer, there was a marked absence of severe and moderate vitamin D deficiency in all subjects, while, 7% of men and, depending on the age-group studied, between 4 and 19% of females had mild vitamin D deficiency. During late-winter, none of the subjects had severe vitamin D deficiency. While none of the men had moderate vitamin D deficiency, 33% of men had mild vitamin D deficiency. In females, depending on the age-group studied, between 32 to 55% of females had mild vitamin D deficiency, and between 2 to 30% of females had moderate vitamin D deficiency, during late-winter. These findings show that inadequate vitamin D status is quite common in healthy Irish subjects, especially and notably so in young girls and more elderly women.     

Low maternal serum vitamin D during pregnancy and the risk for postpartum depression symptoms

Pregnancy is a time of vulnerability for vitamin D insufficiency, and there is an emerging literature associating low levels of 25(OH)-vitamin D with depressive symptoms. However, the link between 25(OH)-vitamin D status in pregnancy and altered risk of postnatal depressive symptoms has not been examined. We hypothesise that low levels of 25(OH)-vitamin D in maternal serum during pregnancy will be associated with a higher incidence of postpartum depressive symptoms. We prospectively collected sera at 18 weeks gestation from 796 pregnant women in Perth (1989–1992) who were enrolled in the Western Australian Pregnancy Cohort (Raine) Study and measured levels of 25(OH)-vitamin D. Women reported postnatal depressive symptoms at 3 days post-delivery. Women in the lowest quartile for 25(OH)-vitamin D status were more likely to report a higher level of postnatal depression symptoms than women who were in the highest quartile for vitamin D, even after accounting for a range of confounding variables including season of birth, body mass index and sociodemographic factors. Low vitamin D during pregnancy is a risk factor for the development of postpartum depression symptoms.     

Prevalence of suicidality during pregnancy and the postpartum

Summary This review examined the available prevalence estimates of suicidality (suicide deaths, attempts, and ideation including thoughts of self harm) in pregnancy and the postpartum. Studies that used defined community or clinic samples were identified through multiple electronic databases and contacts with primary authors. Definitions of and measurement of suicide deaths, intentional self-harming behavior, suicide attempts, and thoughts of death and self-harm were varied and are described with each study. While suicide deaths and attempts are lower during pregnancy and the postpartum than in the general population of women, when deaths do occur, suicides account for up to 20% of postpartum deaths. Self-harm ideation is more common than attempts or deaths, with thoughts of self-harm during pregnancy and the postpartum ranging from 5 to 14%. The risk for suicidality is significantly elevated among depressed women during the perinatal period, and suicide has been found to be the second or leading cause of death in this depressed population.     

Prevalence and correlates of suicidal ideation during pregnancy

Data are scarce regarding the prevalence and risk factors for antenatal suicidal ideation because systematic screening for suicidal ideation during pregnancy is rare. This study reports the prevalence and correlates of suicidal ideation during pregnancy. We performed cross-sectional analysis of data from an ongoing registry. Study participants were 2,159 women receiving prenatal care at a university obstetric clinic from January 2004 through March 2010. Multiple logistic regression identified factors associated with antenatal suicidal ideation as measured by the Patient Health Questionnaire. Overall, 2.7% of the sample reported antenatal suicidal ideation. Over 50% of women who reported antenatal suicidal ideation also reported major depression. In the fully adjusted model antenatal major depression (OR = 11.50; 95% CI 5.40, 24.48) and antenatal psychosocial stress (OR = 3.19; 95% CI 1.44, 7.05) were positively associated with an increased risk of antenatal suicidal ideation. We found that being non-Hispanic White was associated with a decreased risk of antenatal suicidal ideation (OR = 0.51; 95% CI 0.26–0.99). The prevalence of antenatal suicidal ideation in the present study was similar to rates reported in nationally representative non-pregnant samples. In other words, pregnancy is not a protective factor against suicidal ideation. Given the high comorbidity of antenatal suicidal ideation with major depression, efforts should be made to identify those women at risk for antenatal suicidal ideation through universal screening.     

An investigation of vitamin D status in alopecia areata

Alopecia areata (AA) is a type of non-scarring, recurrent patchy loss of hair in hair-bearing areas and is mostly of autoimmune origin. Previous studies have suggested that some autoimmune diseases were found to be associated with vitamin D deficiency. The current study was designed to assess the levels of serum 25-hydroxy vitamin D and C-reactive protein in AA, as compared with controls and to further identify the association between vitamin D levels and disease severity in patients with AA. This cross-sectional study included 45 patients with AA and 45 healthy volunteers. Clinical and anthropometric parameters were recorded, according to a pre-designed proforma. Serum 25-hydroxy vitamin D and high-sensitivity C-reactive protein were estimated using ELISA kits. The severity of AA was determined using Severity of Alopecia Tool (SALT) score. We observed a significant rise in systemic inflammation as seen by elevated high-sensitive C-reactive protein levels and lowered 25-hydroxy vitamin D levels in patients with alopecia areata, compared to controls (p?=?0.001). The levels of 25-hydroxy vitamin D showed a significant negative correlation with disease severity, while hs-CRP levels showed a significant positive correlation with disease severity (ρ?=???0.714, p?=?0.001 and ρ?=?0.818, p?=?0.001). Our results suggest significant systemic inflammation and vitamin D deficiency in alopecia areata, more so with increasing disease severity. This gains particular importance in the treatment of alopecia areata in future, as supplementing vitamin D to AA patients would result in reducing the disease severity and inducing remission.     

Socioeconomic status and prevalence of toxoplasmosis during pregnancy

Two hundred and thirty-six women with previous bad obstetric history (BOH), belonging to different socio-economic groups were investigated for the presence of Toxoplasma specific antibodies (IgG/IgM) using commercial diagnostic kits. The study showed a higher percentage of IgG seropositivity in women of low socioeconomic group (LSG) compared to those of high socioeconomic group (HSG). Specific IgM positivity indicative of possible acute infection, was higher in women of HSG, emphasizing the need for educating pregnant mothers on preventive measures. However, there is a need to undertake in-depth studies to understand the significance of the presence of IgM in women with BOH.     

Race and vitamin D status and monitoring in male veterans

African Americans have lower vitamin D levels and reduced health outcomes compared to white Americans. Vitamin D deficiency may contribute to adverse health outcomes in African Americans. We hypothesized that race would be associated with vitamin D status and testing in African Americans veterans, and that vitamin D status is a major contributor to health care costs in African American veterans compared to white veterans. A retrospective analysis of the medical data in the Veterans Integrated Service Network 9 (southeastern United States) was performed, and 14148 male veterans were identified. Race was designated by the patient and its relationship to vitamin D levels/status and costs was assessed. Vitamin D levels were significantly lower and the percent of patients with vitamin D deficiency was significantly higher in African American veterans. This difference was independent of latitude and seasonality. Vitamin D testing was done significantly more in white veterans compared to African American veterans (5.4% vs 3.8%). While follow-up testing was 42% more likely if a patient was found to be vitamin D deficient, white veterans were 34% more likely than African American veterans to have at least 1 follow-up 25-hydroxyvitamin D performed. African American veterans had significantly higher health care costs, which were linked to lower vitamin D levels; however, the cost differential persisted even after adjusting for vitamin D status. Vitamin D deficiency is highly prevalent in African American veterans and needs improved management within the Veteran Administration system. Vitamin D status appears not to be the sole contributor to increased health care costs in African American veterans.     

Maternal vitamin D intake during pregnancy is inversely associated with asthma and allergic rhinitis in 5-year-old children

Background Vitamin D is known to have a number of immunological effects and it may play a role in preventing allergic diseases.
Objectives To study the effect of maternal intake of vitamin D during pregnancy on the emergence of asthma, allergic rhinitis (AR), and atopic eczema by the age of 5 years in children with HLA-DQB1-conferred susceptibility for type 1 diabetes.
Methods Children (1669) participating in the population-based birth cohort study were followed for asthma, AR, and atopic eczema assessed by validated questionnaire at 5 years. Maternal diet was assessed by a food-frequency questionnaire.
Results The mean maternal intake of vitamin D was 5.1 (SD 2.6) μg from food and 1.4 (2.6) μg from supplements. Only 32% of the women were taking vitamin D supplements. When adjusted for potential confounders, maternal intake of vitamin D from food was negatively related to risk of asthma [hazard ratio (HR) 0.80; 95% confidence interval (CI) 0.64–0.99] and AR [HR 0.85; 95% CI 0.75–0.97]. Vitamin D supplements alone were not associated with any outcome. Adjustment for maternal intake of other dietary factors did not change the results.
Conclusion Maternal vitamin D intake from foods during pregnancy may be negatively associated with risk of asthma and AR in childhood.     

Regulation of cytokine responses by seasonality of vitamin D status in healthy individuals

Phage display technology has been utilized to select target molecules against circulating antibodies. The aims of this study were to isolate a peptide that binds with serum from Crohn's disease (CD) patients and to examine its diagnostic and pathogenic significance. A phage display library was constructed using cDNA from Caco-2 cells. Affinity selection using this cDNA library and serum samples from patients with CD was then performed. Phage clones that specifically reacted with the CD sera were then selected using a phage enzyme-linked immunosorbent assay (ELISA). After the DNA sequences of the selected phages were determined and converted to amino acid sequences, the synthesized peptides were examined using an ELISA. The effect of the synthesized peptides on cytokine release from cultured blood mononuclear cells was investigated. An ELISA analysis for TCP-353 demonstrated that while 61·7% of the samples from CD patients were seroreactive, seroreactivity was less common among patients with ulcerative colitis (7·3%), acute colitis (0%) or colon cancer (11·4%) and among normal subjects (2·8%). The induction of interleukin (IL)-1β, IL-6 and tumour necrosis factor (TNF)-α release, but not IL-10 release, in response to TCP-353 peptide was enhanced in CD mononuclear cells only. We isolated a novel peptide that specifically binds to CD sera and stimulates the proinflammatory responses of CD mononuclear cells. TCP-353 may have diagnostic, pathogenic and therapeutic significance with regard to the treatment of CD.     

Prevalence and severity of carpal tunnel syndrome (CTS) during pregnancy

Carpal Tunnel Syndrome (CTS) is the entrapment of Median nerve at wrist. Pregnancy can affect prevalence and severity of CTS. In this study frequency and severity of CTS in pregnancy was evaluated. In this study 100 pregnant women were evaluated by Hand symptoms, CTS provocation tests (Tinel and Phalen) and for definite diagnosis of CTS standard EDX studies were used. For this purpose sensory and motor distal latency of Median were measured and compared with ulnar nerve. 17% of pregnant women had CTS with 23.5% bilateral involvement and 17.5% severe CTS. Prevalence of hand symptom and clinical sign of CTS (phalen and tinel sign) were 36% and 26% respectively. Results indicated that prevalence of CTS in pregnant women was significant. Although hand signs and symptoms are useful, EDX study is more reliable.     

Relation of maternal vitamin D status with gestational diabetes mellitus and perinatal outcome

Objective

To investigate the relationship between maternal vitamin D status and glucose intolerance, and its impact on pregnant women and their newborns.

Methods

A cohort of pregnant women were divided into three groups: women with gestational diabetes mellitus, ones with normal results both after the 50 gr and 100 gr OGTT (CG-1) and ones having a positive result after the 50 gr OGTT screening but negative results for gestational diabetes mellitus (GDM) after the 100 gr OGTT (CG-2)

Results

The newborn length in CG-1 was greater than in GDM and CG-2 (p= 0.002 and p= 0.02). Fasting blood glucose and insulin resistance (IR) were negatively correlated with length of the newborns (r=−0.3, p=0.03 and r=−0.3, p=0.01). The newborns of women with GDM had lower APGAR-1 and 5 scores than those of CG-1 and CG-2 (APGAR-1 p= 0.001 and p= 0.004, APGAR-5 p=0.005 and p=0.007, respectively). APGAR scores were correlated negatively with IR (APGAR-1 r=−0.32, p=0.01, APGAR-5 r=−0.3, p=0.03) and positively with 25OHD levels (APGAR-1 r=0.3, p=0.01, APGAR-5 r=0.3, p=0.02).

Conclusion

Vitamin D deficiency, gestational diabetes and insulin resistance are interrelated. Severe vitamin D deficiency during pregnancy is associated with poor pregnancy and neonatal outcome.     

Calcium and vitamin D status of pregnant teenagers in Maiduguri, Nigeria.

This study investigates parameters related to calcium and bone metabolism by determining the concentrations of total calcium, 25-hydroxyvitamin D, 1,25-dihydroxyvitamin D, parathyroid hormone, and phosphorous in young pregnant women. The patient population was 30 pregnant Nigerian teenage women grouped by trimester (10 per group), 10 women immediately following delivery, and 21 healthy age-matched controls. On the basis of serum prealbumin levels, the general nutrition of the pregnant women was found to be significantly below that of the more privileged and better-educated nonpregnant controls. The mean total calcium concentration in sera of the third-trimester women was 8.83 mg/dL, which was significantly below that of the controls (9.77 mg/dL) and the first-trimester group (9.30 mg/dL). Despite the 10% to 15% decline in the serum level of total calcium during pregnancy, the parathyroid hormone level decreased markedly from 0.60 to 0.61 ng/mL in the first and second trimesters to 0.41 ng/mL in the third trimester. Serum vitamin D and 1,25-dihydroxyvitamin D levels in the second and third trimesters were within the normal range. These data indicate that toward the end of gestation, pregnant teenagers in northern Nigeria appear to become calcium deficient and do not exhibit the expected increase in serum parathyroid hormone levels normally seen in pregnant women.     

Prevalence of anxiety and depression during pregnancy in a private setting sample

Summary Objectives: To estimate the prevalence and risk factors for antenatal anxiety (AA) and antenatal depression (AD). Methods: We performed a cross sectional study of 432 women attending a private clinic in the city of Osasco, S?o Paulo, from 5/27/1998 to 5/13/2002. The following instruments were used: Spielberger state-trait anxiety inventory (STAI), Beck depression inventory (BDI), and a questionnaire for socio-demographic and obstetric data. Inclusion criteria were: pregnant women with no past or present history of depression, psychiatric treatment, alcohol or drug abuse and no clinical and obstetric complications. The prevalence of AA, according to STAI, and AD, according to Beck Inventory, were estimated with 95% confidence intervals (95% CI). Odds ratios and 95% CI were used to examine the association between AA and AD and exposures variables. Results: The prevalence of AA, state and trait were 59.5 (95 CI%: 54.8:64.1%) and 45.3% (95% CI: 40.6:50.0), respectively. The prevalence of AD was 19.6 (95% CI:15.9:23.4). In the multivariate analysis, AA-trait (OR: 5.26; 95% CI 2.17:12.5, p < 0.001), AA-state (OR: 2.27; 95% CI 1.08:4.76, p = 0.02) and AD (OR: 2.43; 95% CI 1.40:4.34, p = 0.002) were associated with lower women’s educational level. AA-trait (OR: 3.43; 95% CI 1.68:7.00, p = 0.001), AA-state (OR: 2.22; CI 95% 1.09:4.53, p = 0.02) and AD (OR: 2.82; CI 95% 1.35:5.97, p = 0.005) were also associated with not being married. AA-trait was associated with lower women’s income (OR: 2.22; 95% CI 0.98:5.26, p = 0.05) and not being white (OR: 1.7; 95% CI 1.00:2.91, p = 0.04), while AD was associated with lower couple’s income (OR: 2.43; 95% CI 1.40:4.34, p = 0.001) and greater number of previous abortions (OR: 2.21; 95% CI 1.23:3.97, p = 0.009). Conclusions: Prevalence of AA and AD were high in this sample of women attending a private care setting, particularly AA state and trace. AA and AD were associated with similar socio-demographic and socio-economic risk factors, suggesting some common environmental stressors may be involved.
