Vitamin D has immunomodulatory and antifibrotic properties, and therefore used for treatment of many of chronic liver disease [1]. Although there are many reports on the relationship between serum 25-hydroxyvitamin D3 levels and chronic liver diseases, but the relationship between hepatitis B virus e antigen (HBeAg) and vitamin D level is still unclear. The modification and prevention of vitamin D deficiency needs an accurate illustration of the current position in each region. Vitamin D level in patients with HBV is relatively an important issue, which has been studied in many researches. As different papers published in national and international journals.

Chronic kidney disease (CKD) is a highly prevalent disease, imposing high mortality rates worldwide, and it is closely related to cardiovascular events. Vitamin D deficiency is very prevalent in patients with CKD from the earliest stages of the disease, and it has been associated with higher mortality. In order to assess the prognostic implications of vitamin D deficiency in CKD, we undertook a literature review, searching different databases in October 2018 for publications related to vitamin D in patients with CKD and hypovitaminosis D, and not on dialysis. The main cause of death in these patients is cardiovascular disease. Vitamin D is one of the first parameters that CKD changes and has an important prognostic role in this entity. Deficient levels in blood are associated with increased cardiovascular risk and survival impacts, independently of cardiovascular disease. Treatment with paricalcitol appears to reduce this risk. However, the evidence analyzed is insufficient to establish an association between vitamin D levels and the progression of kidney disease. 

Chronic obstructive pulmonary disease (COPD) is the third leading cause of death and its prevalence and incidence is also related to smoking behavior [1]. COPD is still a chronic inflammatory and progressive disease caused by multifactorial agents including environmental pollutants [2]. Besides that, it is emerging that endogenous epigenetic factors induced by lifestyle and environment [3] could play a role in the etiopathogenesis of the disease [4]. In the last years, several authors suggested that low vitamin D levels seem to be related with the increase of COPD manifestations [5]. Moreover, a multicentre, double-blind, randomised controlled trial documented that vitamin D supplementation protects against moderate or severe exacerbation of the disease, but not by upper respiratory infections [6]. However, low levels of vitamin D can be extended to many other diseases, including multiple sclerosis, diabetes, colon rectal cancer, headache or drug use [7-11]. Moreover, it is also important to remember that Vitamin D deficiency is common in high latitude regions, such as northern Europe, New Zealand, northern USA, and Canada where weaker ultraviolet B rays is not able to produce enough vitamin D. Finally, methodological factors (using low sensitivity methods) could contribute to misleading evaluation of circulating vitamin D levels. In any case, here we shall remind that vitamin D has a fundamental role in immunity [12]. In particular, it has been reported that vitamin D is able to shift the pro-inflammatory T-helper cell 1 to anti-inflammatory T-helper cell 2 [13]. Therefore, benefits of vitamin D supplementation in chronic diseases which directly or indirectly affect immune system are obvious. Today, the burden of COPD in never smokers is higher than previously believed. Therefore, more research is needed to unravel the characteristics of non-smokers COPD [1]. Notably, vitamin D levels are reported to be significantly lower in smoker’ssubjects than in non-smokers ones [14]. Therefore, low plasma vitamin D levels in COPD seems to be more a causality than a correlation.

The NIH has published treatment guidelines for treating COVID-19 patients in the hospital. However, as of this writing, there are no established protocols for treating COVID-19 positive patients in primary care. Accordingly, this investigator has taken on the task of reviewing the medical literature to be able to propose evidence-based protocols for treating COVID-19 positive patients in primary care. The CDC is advising people to do nothing when they find out they are positive for COVID-19 unless they have symptoms. The evidence from the literature irrefutably shows COVID-19 infection evokes a massive and deadly hyperinflammatory response called the “Cytokine storm” and that Cytokine levels in the blood have a predictive value in identifying an impending Cytokine storm. With such data primary care providers can effectively lower Cytokine levels and prevent critical illness and death. Accordingly, this paper presents identification of the problem of not having standard practices in primary care for people who are positive for COVID-19 and not knowing who is at risk. Moreover, the evidence shows that knowing vitamin D levels and correcting deficiencies can go a long way in reducing Cytokine levels. Additionally, the literature review presents evidence that undeniably shows the stark possibility that many of the COVID-19 related deaths can be prevented by identifying who is at risk for the Cytokine storm and other complications and providing early treatment even before symptoms appear.

When grouping children with psoriasis depending on TaqI (T/C) genotypes of the VDR gene, the youngest age of disease onset and the longest duration of dermatitis (5.60 ± 0.77 years and 4.90 ± 0.68 years, respectively) showed up in case of the CC genotype. In case of the TT genotype, disease onset coincided with an older age, and the history of present illness was the shortest (10.26 ± 0.64 years and 2.59 ± 0.58 years, respectively). PASI (20.32 ± 3.43) and BSA (40.00 ± 6.11) severity indices were the highest and of statistically significant difference to those in other groups in the presence of the CC genotype. In case of the TC genotype, the index PGA (2.80 ± 0.15) was the lowest and made a statistically significant difference to the values of other groups. A negative correlation between vitamin D levels and the PASI, PGA, BSA was identified in children holding CC and TC genotypes. Conclusion: The clinical presentation of dermatitis and its epidemiological features in children with psoriasis, namely the age of disease onset, duration of exacerbation, body surface area and the intensity of psoriasis symptoms depend on vitamin D serum levels and genotypes of the TaqI polymorphic variant of the VDR gene.

Background: Pre-eclampsia and eclampsia have remained a major global public health threat in contributing significantly to maternal and perinatal morbidity and mortality. Based on the inverse relationship between serum 1,25(OH)2D3 levels and plasma renin activity found previously, it is speculated that 1,25(OH)2D3 might be a negative endocrine regulator of renin production in vivo. During pregnancy, vitamin D may play a role in implantation and placental function potentially due to angiogenic, immunomodulatory, and antiinflammatory effects. Vitamin Ddeficiency can affect the health of both mother and fetus by increasing the production of inflammatory cytokines and stimulating the activity of T-regulating cells. Vitamin D is emerging as a promising agent for pre-eclampsia prevention. Aims and objectives: The objective of this study is to compare the vitamin D levels in pre-eclamptic and healthy non-pre-eclamptic pregnant women in labor and find out the relationship between vitamin D levels and pre-eclampsia. Methodology: The present cross-sectional study was carried out on pregnant women with pre-eclampsia in labor. For each case with pre-eclampsia, one uncomplicated, normotensive pregnant woman in labor was taken as control. On admission to the labor room detailed history, physical examination followed by thorough obstetrics and systemic examination was done. Required investigations were done including vitamin D and calcium levels. Maternal and fetal condition was monitored during labor/cesarean section, mode of delivery, maternal and fetal outcomes were recorded. After delivery, 2cc of cord blood was collected in a serum tube and sent for vitamin D levels. Data was collected and analyzed statistically using Epi-info version 7.1.Results: It was observed that the patients in both groups were comparable with respect to demographic and obstetrics characteristics except for significantly high BP in group I. Vitamin Ddeficiency (i.e. < 20 ng/ml) was significantly more in group I as compared to group II and the difference was highly significant (p < 0.0001). Similarly, the mean maternal calcium levels were significantly lower in group I in comparison to group II (p < 0.0001) i.e. the mean maternal calcium level in group I and group II were 8.03 ± 0.94 and 9.19 ± 0.67 respectively. It was also observed that the level of 25-OH-D in neonates of preeclamptic women was significantly lower than for those of the normal pregnant women (p < 0.0001). Conclusion: Vitamin D deficiency is highly prevalent in all parts of the world. Pregnant women and neonates are highly vulnerable to vitamin D deficiency. Preeclampsia is indeed associated with lower vitamin D levels and the pathophysiology of pre-eclampsia involves vitamin D and calcium metabolism through their role in immunomodulation, angiogenesis and anti-inflammatory effects. From the present study, it was observed that vitamin D and calcium levels were significantly lowered in women with pre-eclampsia as compared to those of the normotensive pregnant women. So early detection of vitamin D and calcium deficiencies may be helpful in preventing occurrence of PET and its complications.

Background: Cardiomyopathy is primarily a disorder of the cardiac muscle that causes myocardial dysfunction and is not the result of disease or dysfunction of other cardiac structures, systemic arterial hypertension and valvular stenosis or regurgitation. Aim: The present study aimed to determine the prevalence of vitamin D deficiency and its correlation with the severity of heart disease in patients with dilated cardiomyopathy (DCMP). Method: 70 ECHO-proven DCMP cases were enrolled from the medicine/ cardiology department of LHMC & associated hospitals and ABVIMS & Dr. RML Hospital, New Delhi from November 2019 to October 2021. DCMP patients with ages more than 18 years who were willing to give consent and does not meet any of the exclusion criteria were enrolled in this study. Results: Mean age of idiopathic DCMP patients was 48.3 ± 15.2. There were more males 48 (69%) than females 22 (31%). The mean ejection fraction was 26.6 ± 7.3, while the mean fractional shortening was 17.6 ± 3.1. Vitamin D deficiency was observed in 90% of patients, among which 68.5% were having moderate vitamin D deficiency and 10% were having severe vitamin D deficiency. Conclusion: In our study, vitamin D levels were inversely correlated with the severity of heart disease in DCMP patients.
