Canine visceral leishmaniasis is associated with cardiac changes. This study was designed to test the hypothesis that vitamin D and coagulation parameters, such as D-dimer, activated partial thromboplastin time (APTT), partial thromboplastin time (PT), mean platelet volume (MPV), and white blood cell (WBC) levels, change in different stages of canine visceral leishmaniasis (CVL). Thirty-two dogs diagnosed with CVL were classified into four different groups: stage I (mild disease), stage II (moderate disease), stage III (severe disease), stage IV (very severe disease), and healthy controls. The groups were based on clinical signs, rapid ELISA/IFAT, hematological and serum biochemical tests, and urinary protein/creatinine ratios. Serum vitamin D levels were positively correlated with MPV (r = 0.503), but negatively correlated with D-dimer (r =-0.326), APTT (r =-0.361), PT (r =-0.289), and WBC (r = -0.384). The dogs with leishmaniasis showed increased WBC levels compared with the control group. Similarly, their vitamin D levels were significantly decreased compared with those in the control group (p<0.05). Severely diseased dogs (stage IV leishmaniasis) showed the lowest vitamin D levels, but there were no significant differences between dogs in the various stages of leishmaniasis. The evidence provided by this study indicates that the CVL dogs had low-grade systemic coagulation and fibrinolytic activation, as indicated by elevated MPV, PT, WBC and D-dimer levels, which may be used as a biomarker of low-grade systemic inflammation in CVL.

Objective.Deficiency of 25-hydroxyvitamin D [25(OH)D] is reported to be common in patients with rheumatoid arthritis (RA); data in patients with juvenile idiopathic arthritis (JIA) are inconsistent. We assessed serum 25(OH)D in children, adolescents and young adults with JIA, in order to identify the risk factors for vitamin D deficiency in patients with JIA.Methods.We evaluated 152 patients with JIA: 115 female, 37 male, mean age 16.2 ± 7.4 yrs; evaluated by onset type, 96 had oligoarticular, 35 polyarticular, 7 systemic, and 14 enthesitis-related arthritis (ERA). Patients were compared with a control group matched for sex and age. All patients and controls underwent laboratory tests of plasma 25(OH)D, parathyroid hormone (PTH), calcium, phosphorus, and bone alkaline phosphatase levels, and dual-energy x-ray absorptiometry examination.Results.Patients with JIA showed significantly reduced 25(OH)D levels compared to controls (p < 0.001), even divided into subtypes (oligoarticular, p < 0.05; polyarticular, p < 0.005; systemic, p < 0.001; ERA, p < 0.005). Patients with active disease and/or frequent relapses had significantly reduced 25(OH)D levels compared to patients with no active disease and no frequent flares (p < 0.005, respectively). Nevertheless, JIA patients had significantly higher PTH levels compared to controls (p < 0.0001). JIA patients with 25(OH)D deficiency showed a significantly lower bone mineral apparent density than those with normal 25(OH)D levels (p < 0.001).Conclusion.JIA patients have reduced 25(OH)D and higher PTH values. This may explain at least in part why JIA patients, despite more effective current drugs, do not achieve bone-normal condition over time. JIA patients with more severe disease could require higher supplementation of vitamin D to maintain normal 25(OH)D serum levels. Longterm studies are needed to investigate the relationship between serum 25(OH)D levels and disease activity in JIA.

Background: Ehrlichiosis is a ricketsial disease transmitted by ticks and characterized by reticuloendothelial hyperplasia, fever, generalized lymphadenopathy, splenomegaly and thrombocytopenia. In this study, it was aimed to determine the blood vitamin D and D-dimer levels in dogs with Ehrlichiosis. Methods: The material of this study consisted of 33 dogs of different breeds, ages and both sexes during the period of 2018-2019. In 33 dogs with and without thrombocytopenia with clinical findings, definitive diagnosis and differential diagnosis were made with clinical examination and laboratory tests. All patients were evaluated for Ehrlichiosis with rapid Snap 4DX test kit. In addition, the diagnosis of the disease was made by PCR analysis. Blood D-Dimer levels were determined in control and study groups. Result: D-Dimer levels were significantly higher in the study groups when compared with the control group. Further, when blood D-vitamin levels of control and study groups were compared, it was found that blood D-vitamin levels were significantly lower in dogs with Ehrlichiosis. In conclusion, in this study, D-dimer levels were significantly increased in dogs with ehlichiosis and can be an adjunct biomarker with other clinical, hematologic and laboratory tests. In addition, serum vitamin D levels were found to be low in both active and acute infected patients in dogs previously exposed to the causative agent, which is closely related to the immune system of vitamin D and serum low vitamin D levels may pave the way for the development of ehrlichiosis disease.

The objectives of this study were to estimate the prevalence of vitamin D deficiency in patients with acute coronary syndrome in comparison with normal individuals and study the correlation between these two conditions. We measured the plasma 25-hydroxy vitamin D (25-OH-D) levels in 60 patients with acute coronary syndromes (ACS) of both gender and in 30 age matched control individuals of both gender without any known cardiovascular or systemic diseases. The levels of 25-OH-D were measured by ELISA method and the results were statically analyzed to find out any possible correlation. We classified the cases according to their plasma 25(OH)D levels. 25(OH)D levels of ≥ 30 ng/ml were considered normal, levels < 30 and > 20 ng/ml were classified as insufficient, while levels of ≤ 20 ng/ml were classified as deficient. In the current study the prevalence of hypovitaminosis D in the patients group was much higher than it was in the control group. Vitamin D deficiency was observed in 80% and insufficiency in 13% of total patients of ACS, there by bringing the total count to 93%. Whereas only 7% of the patients had adequate vitamin D levels. Thus, these results indicate the existence of a significant correlation between the vitamin D deficiency and ACS in comparison to healthy controls

Objective: To determine whether patients with chronic kidney disease (CKD) without dialysis their stage impacts the native vitamin D levels. Methods: Patients over 18 years with chronic kidney disease stage 2-5 without dialysis treatment. They demographic, anthropometric variables, degree of sun exposure, disease etiology and laboratory variables related to bone and mineral disorders were evaluated. Study analytical cross-sectional prospective. Descriptive statistical methods for quantitative and qualitative are characterized, and analytical correlation between levels of vitamin D statistical laboratory tests related to bone and mineral disorders, sun exposure and ethnicity variables for each stage were characterized. By descriptive statistical methods, quantitative and qualitative variables were characterized, and analytical statistical correlation between levels of vitamin D with laboratory tests related to bone and mineral disorders, sun exposure and ethnicity for each stage were practiced. Results: 331 patients were evaluated, with a mean age of 71 years, the mestizo majority (71%), 173 women, main etiology of CKD hypertensive nephropathy (33.2%). 21.1% of patients had normal levels of vitamin D, 70.1% insufficient, and 8.8% in deficit. Negative correlation was detected between the levels of vitamin 25(OH)D and serum creatinine, phosphorus, calcium x phosphorus product, PTH, proteins in urine 24 hours and BMI. Positive correlation for calcium and albumin. Positive statistical significance between the levels of vitamin 25(OH)D and sun exposure for 3b and 4 stages was found. Conclusions: In patients with CKD is common to detect low levels of vitamin 25(OH)D, which can contribute to the generation of secondary hyperparathyroidism.

Psoriasis is an immuno-mediated chronic systemic disease involving cytokines of helper Th1 pathway. Vitamin D has an effect on keratinocyte proliferation, differentiation and immune modulation of immune system especially Th1 pathway, which is altered in psoriatic skin suggesting that Vitamin D may have a role in pathogenesis of psoriasis. To study correlation between psoriasis vulgaris and serum vitamin D. To evaluate serum vitamin D level in psoriasis cases and in control group and correlating vitamin D level with severity and duration of the psoriasis. 57 cases (&#62;15years of age) with psoriasis and 57 healthy subjects were recruited. Psoriasis was clinically diagnosed and severity evaluated by PASI scale. Vitamin D was analysed by enhanced chemilumine scence on vitrus Eci autoanalyzer of Orth clinical diagnostic. Vitamin D deficiency defined as &#60;20ng/ml, insufficiency 20-30ng/ml and sufficient 30-100ng/ml. Vitamin D deficiency in the study was 22.8% in patients and 14% in control group. Vitamin D insufficiency was found in 42.1% of cases and 19.3% of control. According to chi-square the p-value is 0.003 showing significant association. There was a tendency towards decrease in vitamin D level with increase in disease duration. There was negative correlation between vitamin D and PASI score. The study found a significant relationship between vitamin D and psoriasis. Further metanalysis involving larger study population will be required to establish whether vitamin D levels benefits patient with psoriasis vulgaris.

Vitamin D deficiency actives renin-angiotensin-aldosterone system (RAAS) which affects cardiovascular system. Activation of RAAS is associated with pulmonary hypertension (PHT). Relation between vitamin D deficiency and PHT could be therefore suggested. In  our study we compared pulmonary artery pressure between vitamin D deficiency and control groups. 115 consecutive patients (average age: 61.86 ± 5.86) who have detected very low vitamin D (vitamin D levels < 10 ng/ml) were enrolled. 117 age matched persons (average age: 61.74 ± 5.99) were selected as the control group. All groups underwent transthoracic echocardiography. Routine biochemical measurement of 25-OH vitamin D and parathormon (PTH) levels were performed. Baseline characteristics of the study groups were comparable. Systolic pulmonary artery pressure (SPAP) of patients in  the low vitamin D group was higher than the control groups. As a  result our study, a  relation between vitamin D deficiency and pulmonary artery hypertension was revealed.

Background: Transient tachypnea of newborn (TTN) is a common cause of respiratory distress in newborns with estimated incidence of 1-2% of all newborns. Although a self-limiting transient condition but it may cause severe morbidities. This study was conducted to find association of serum vitamin D levels in neonates who develop TTN as compared to normal healthy neonates.Methods: With thorough history with structured questionnaire and lab tests, serum vitamin D levels of 45 neonates who develop TTN were compared with 56 healthy neonates in control group.Results: Out of 45 neonates who develop TTN 39(86.7%) were deficient in vitamin D as compared to control group where 33(58.9%) out of 56 healthy neonates were deficient in vitamin D.Conclusions: Lower vitamin D levels at birth in term neonates is associated with increased risk of developing TTN and vitamin D may have a role in its pathogenesis.

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.

INTRODUCTION: We aimed to compare the mean platelet volume (MPV) and plateletcrit (PCT) and vitamin-mineral levels in pediatric celiac disease patients with the healthy control group and to compare the results with the literature. METHODS: In this study, clinical and laboratory data of 80 pediatric patients diagnosed with celiac disease (CD) between July 2017 and December 2018 and 42 healthy children in the same age group were retrospectively analyzed. RESULTS: There was no significant difference between the groups in terms of age and gender (p=0.383, and p=0.462, respectively). The frequency of anemia, folate, iron and vitamin D deficiencies was higher in celiac patients compared to the control group (p=0.001, p=0.027, p<0.001, and p<0.001, respectively). When the patients were evaluated according to their complete blood count and vitamin-mineral levels; hemoglobin (Hb), mean corpuscular volume (MCV), ferritin and vitamin D levels were found to be significantly lower in the CD group compared to the control group (p<0.001, p=0.026, p<0.00, and p=0.001, respectively). Platelet (PLT), PCT, MPV levels were found to be significantly higher in the CD group compared to the control group (p=0.010, p<0.001, and p<0.001, respectively). We found a weakly negative correlation between the vitamin D levels and the degree of the Marsh classification (r: -0.273, and p=0.023). DISCUSSION AND CONCLUSION: Our study have shown that MPV, PCT values are higher and Hb, folate, iron and vitamin D levels are lower in patients with CD compared to healthy controls. We recommend investigating other nutrient deficiencies besides iron deficiency, especially in treatment-resistant anemias. We think that the correlation between vitamin D levels and the degree of histological damage should be elucidated with larger-scale and more comprehensive studies.
