Background and aim: Vitamin D deficiency is frequently reported in patients with SARS-CoV-2 infection. The aim of this study was to correlate the 25OH-Vitamin D serum concentrations with clinical parameters of lung involvement, in elderly patients hospitalized for SARS-CoV-2 infection. Methods: Sixty-five consecutive COVID-19 patients (mean age 76 ± 13 years) and sixty-five sex- and age-matched control subjects (CNT) were analyzed. The following clinical parameters, including comorbidities, were collected at admission: type of pulmonary involvement, respiratory parameters (PaO2, SO2, PaCO2, PaO2/FiO2), laboratory parameters (including 25OH-vitamin D, D-dimer, C-reactive protein). Results: Significantly lower vitamin D serum levels were found in COVID-19 patients than in CNT (median 7.9 vs 16.3 ng/mL, p = 0.001). Interestingly, a statistically significant positive correlation was observed between vitamin D serum levels and PaO2 (p = 0.03), SO2 (p = 0.05), PaO2/FiO2 (p = 0.02), while a statistically significant negative correlation was found between vitamin D serum levels and D-dimer (p = 0.04), C-reactive protein (p = 0.04) and percentage of O2 in a venturi mask (p = 0.04). A negative correlation was also observed between vitamin D serum levels and severity of radiologic pulmonary involvement, evaluated by computed tomography: in particular, vitamin D was found significantly lower in COVID-19 patients with either multiple lung consolidations (p = 0.0001) or diffuse/severe interstitial lung involvement than in those with mild involvement (p = 0.05). Finally, significantly lower vitamin D serum levels were found in the elderly COVID-19 patients who died during hospitalization, compared to those who survived (median 3.0 vs 8.4 ng/mL, p = 0.046). Conclusions: This study confirms that 25OH-vitamin D serum deficiency is associated with more severe lung involvement, longer disease duration and risk of death, in elderly COVID-19 patients. The detection of low vitamin D levels also in younger COVID-19 patients with less comorbidities further suggests vitamin D deficiency as crucial risk factor at any age.

Background:Vitamin D regulates the innate and adaptive immune system responses and low vitamin D levels have been associated with the increased risk of respiratory tract infections (1). Vitamin D deficiency has been recently reported to interfere with the prognosis of COVID-19 (2,3).Objectives:The aim of this study was to correlate the 25OH-vitamin D serum levels with lung involvement and disease severity, in a cohort of elderly patients hospitalized for SARS-CoV-2 infection.Methods:Sixty-five COVID-19 patients (mean age 76±13 years) and sixty-five sex- and age-matched control subjects (CNT) were included in the study. Respiratory parameters (PaO2, SO2, PaCO2, PaO2/FiO2), clinical and laboratory parameters (including 25OH-vitamin D, D-dimer, C-reactive protein) and type of radiological pulmonary involvement were collected at hospital admission. Statistical analysis was performed by non-parametric tests.Results:Vitamin D sufficiency (>30 ng/ml), insufficiency (between 20 and 30 ng/ml), deficiency (between 10 and 20 ng/ml) and severe deficiency (<10 ng/ml) were observed respectively in 11, 11, 21 and 57 % of COVID-19 patients. Vitamin D serum levels were found significantly lower in COVID-19 patients than in CNT (median 8 vs 16 ng/ml, p=0.001). A statistically significant positive correlation was observed between vitamin D serum levels and SO2 (p=0.05), PaO2 (p=0.03), PaO2/FiO2 (p=0.02). A statistically significant negative correlation was found between vitamin D serum levels and severity of radiologic pulmonary involvement: vitamin D was significantly lower in COVID-19 patients with either diffuse/severe interstitial lung involvement (p=0.05) or multiple lung consolidations (p=0.0001) than in those with mild radiological lung involvement. Significantly lower vitamin D serum levels were found in COVID-19 patients who died during hospitalization, compared to those who survived (median 3 vs 8 ng/ml, p=0.05). Finally, a statistically significant negative correlation was found between vitamin D serum levels and D-dimer (p=0.04), C-reactive protein (p=0.04) and disease duration (p=0.05).Conclusion:This study confirms that severe vitamin D deficiency is associated with more severe lung involvement, longer disease duration and risk of death in elderly COVID-19 patients.References:[1]Cutolo M, et al.

Abstract Abstract 5056 OBJECTIVE To investigate the relation between elevated levels of C-reactive protein (CRP) and D-dimer, and to study whether D-dimer levels can be interpreted in relation to elevated levels of CRP in the prediction of a pulmonary embolism in order to increase its specificity without decline in sensitivity. METHODS Between august 2004 and april 2007 (33 months) serum levels of C-reactive protein (mmol/L) and D-dimer (mmol/L) were cross-sectionally collected and pulmonary embolisms on CT-angiograms were scored within 48 hours. The study was devided into three parts. First, characteristics of excluded persons were studied. Second, the correlation between CRP and D-dimer level was considered in those with a defined (i.e. values with < and > symbols excluded) biomarker level. Finally, the effect of CRP level on the sensitivity of D-dimer for pulmonary embolisms was examined. RESULTS CRP and D-dimer levels were positively correlated ( r = 0.37; p < 0.001), and both were increased in persons with a pulmonary embolism (CRP: p = 0.02; D-dimer: p < 0.001). 14 % of variability in D-dimer level was explained by CRP level. Median D-dimer levels were increased in the pulmonary embolism (PE) group, however, the increase in D-dimer level by CRP quartile as was found in the non-PE was not seen in de PE-group. Adding the interaction term of CRP and D-dimer to the statistical model showed some influence on the area under the curve (AUC). Nevertheless, this was not significantly different from the model with only D-dimer levels. However, when stratified for CRP quartile, ROC-curves of the predictive effect of D-dimer on pulmonary embolisms showed a decrease in AUC by increment of CRP quartile. CONCLUSION CRP and D-dimer are positively correlated, and both predictive of PE. The predictive value of D-dimer for PE declines by increment of CRP, although this seems to be safely for a broader range of accompanied CRP levels.

Purpose To evaluate for an association between 25-hydroxyvitamin D levels (vitamin D) and outcome measures in patients with melanoma after evaluation is controlled for systemic inflammatory response (SIR) on the basis of simultaneous C-reactive protein (CRP) measurement. Materials and Methods Plasma samples from 1,042 prospectively observed patients with melanoma were assayed for vitamin D and CRP. The associations of demographics and CRP with vitamin D were determined, followed by a determination of the association between vitamin D and stage and outcome measures from the date of blood draw. The vitamin D level was considered sufficient if it was 30 to 100 ng/mL. Kaplan-Meier and Cox regression analyses were performed. Results The median vitamin D level was 25.0 ng/mL. The median follow-up time was 7.1 years. A lower vitamin D was associated with the blood draw during fall/winter months (P < .001), older age (P = .001), increased CRP (P < .001), increased tumor thickness (P < .001), ulcerated tumor (P = .0105), and advanced melanoma stage (P = .0024). On univariate analysis, lower vitamin D was associated with poorer overall (OS; P < .001), melanoma-specific survival (MSS; P = .0025), and disease-free survival (DFS; P = .0466). The effect of vitamin D on these outcome measures persisted after adjustment for CRP and other covariates. Multivariable hazards ratios per unit decrease of vitamin D were 1.02 for OS (95% CI, 1.01 to 1.04; P = .0051), 1.02 for MSS (95% CI, 1.00 to 1.04; P = .048), and 1.02 for DFS (95% CI, 1.00 to 1.04; P = .0427). Conclusion Lower vitamin D levels in patients with melanoma were associated with poorer outcomes. Although lower vitamin D was strongly associated with higher CRP, the associations of lower vitamin D with poorer OS, MSS, and DFS were independent of this association. Investigation of mechanisms responsible for these associations may be of value to patients with melanoma.

Abstract Objectives The present study aimed to evaluate the presence of any relationship between vitamin D and prognostic factors among patients infected with SARS-CoV-2. Methods This retrospective cross-sectional study was conducted among patients admitted from March to August 2020 in a referral hospital, Tehran, Iran. All patients aged 18–65 who had not any comorbidity participated in the study. The diagnosis of COVID-19 was established using the rRT-PCR test for SARS-CoV-2 detection. Then the incidence of lung involvement and biochemical markers including vitamin D level, c-reactive protein, D-dimer, lymphocyte count, platelet count, white blood cell count, and lactic acid dehydrogenase, were extracted through medical records. Results Altogether, 84 patients met our study criteria, and the information of 68 (80.9%) participants were collected. Among all 68 patients, 45 (66.2%) were male. The mean (SD) age of all participants was 52.4 (10.4) years old. Among 24 (35.2%) clients who died due to SARS-CoV-2, 20 (83.3%) patients were male (p=0.02). The mean (SD) of vitamin D level was 24.1 (13.6) ng/dL. No association between vitamin D level and prognostic factors, including CRP, lymphocyte count, D-dimer, LDH, and HRCT scan score, was observed. Also, the vitamin D level of the dead patients was not significantly different from that of the treated patients. Conclusions Our findings indicated no significant relationship between vitamin D level and prognostic factors or outcomes of patients infected with SARS-CoV-2.

Introductionand objectives Schizophrenia accompanies with elevated C-reactive protein (CRP) and vitamin D deficiency. However, there are scarce documentations regarding bipolar disorder and methamphetamine-induced psychotic disorder.AimTo compare serum levels of vitamin D, parathyroid hormone (PTH), calcium, phosphorus and CRP levels in psychotic disorder patients and control group.MethodsA case-control study was conducted on four groups: acute phase of schizophrenia, acute manic episode of bipolar disorder, methamphetamine-induced psychotic disorder and healthy control subjects. Sample size was 45 in each group. Weekly duration of sun exposure, monthly vitamin D intake and serum levels of vitamin D, calcium, phosphorus, PTH and CRP were assessed. Brief Psychiatric Rating Scale (BPRS) was used to evaluate psychotic symptoms.ResultsDuration of sun exposure and monthly vitamin D intake were comparable among groups. Serum levels of vitamin D, calcium and phosphorus were not statistically different between groups (P = 0.463, P = 0.086 and P = 0.339, respectively). Serum levels of PTH were significantly higher in control group (P < 0.001). CRP levels were significantly lower in control subjects (P < 0.001). The levels of serum vitamin D and CRP did not show statistically significant difference among three groups of patients.ConclusionAcute psychotic disorders seem to be associated with higher CRP and lower PTH levels. Clinical importance of the findings and relation of these differences to the metabolic and inflammatory bases of psychosis are not clear yet.Disclosure of interestThe authors have not supplied their declaration of competing interest.

The emerging coronavirus disease (COVID-19) swept the world, affecting more than 200 countries and territories. As of August 22, 2020, the pandemic infected more than 23,329,752 including 807,054 patients who have died. Although the main clinical features of the pandemic disease are respiratory, cerebrovascular comorbidities emerged as one of the leading causes of death associated with COVID-19. Different case reports have indicated that C-reactive protein (CRP) and D-dimer (pro-inflammatory biomarkers) were elevated in COVID-19 patients, which can significantly increase the risk of ischemic stroke. Available data on cerebrovascular complications in COVID-19 patients were collected and a meta-analysis was designed and carried out to evaluate the risk of severity and mortality associated with high levels of CRP and D-dimer levels in COVID-19 patients. In addition, we aimed to describe the overall event rate of pre-existing cerebrovascular disease in COVID-19 patients. In our analysis, 5,614 cases have been studied, out of these patients 164 cases have developed cerebrovascular comorbities. Cerebrovascular comorbidity increased the risk of disease severity (odd ratio = 4.4; 95% CI: 1.48 to 12.84) and mortality (odd ratio = 7.0; 95% CI: 2.56 to 18.99). Statistical analyses showed that CRP and D-dimer serum levels were elevated by six-folds in the severe cases of COVID-19 patients. This significant increase in these two proteins levels can serve as a vital indicator for COVID-19 patients who are at increased risk of severe COVID-19 cerebrovascular complications, such as stroke.
