Background: Vaccine apprehension poses a serious threat to global health. While there has been a tremendous global effort to create a vaccine against coronavirus disease 2019 (COVID-19), little is known about its reception in Iraq. Therefore, we sought to examine COVID-19 vaccine acceptance, hesitation, and related elements in the Iraqi population. Methods: Between the 19th of May and the 22nd of September 2021, a descriptive, cross-sectional web-based survey was conducted employing a quantitative approach. Respondents from both sexes aged 18 years and above who live in Iraq and agreed to participate were included. An anonymized online structured questionnaire was designed based on data from prior research on vaccine hesitation in general, and COVID-19 vaccination reluctance specifically. Results: A total of 1221 eligible participants from various regions in Iraq actively participated in the short web-based questionnaire. The overall acceptance rate of the COVID-19 vaccine was 56.2%, with a greater acceptance rate among younger male participants (p<0.05). Marital status had no significant association (p=0.834). Urbanization influenced the acceptance rate significantly (p=0.002). The barriers to receiving the COVID-19 vaccine were exemplified by the vaccine not being evaluated for a sufficient period in 51.4% of the responses, as well as concerns about future side effects in 76.6% of the responses and a lack of efficacy in 55.7% of the responses. The Pfizer-BioNTech vaccine received 39.6% preference and participants confidence, followed by the Oxford/AstraZeneca vaccine at 18.1% and the Sinopharm vaccine at 14.6%. Conclusions: COVID-19 vaccination apprehension was discovered in almost half of the study population. Lack of understanding about vaccination eligibility, anxiety about adverse events and vaccine efficacy, and distrust in the government were independently predictive of vaccine hesitation.

Background: Diabetes patients have a higher chance of developing dyslipidemia and increased release of free fatty acids, which participate in developing insulin-resistant fat cells. On the other hand, vitamin D insufficiency is linked to the evolution of type 2 diabetes mellitus (T2DM). This study examines the impact of vitamin D serum levels on lipid profiles and insulin resistance concerning glycemic indices in obese T2DM patients. Methods: During the data collecting stage, 47 diabetes patients were chosen from the out-patient clinic. The control individuals were selected from the general population and were equivalent to the matching patients, with a total of 43 healthy participants. After an overnight fast, a venous blood sample was collected from each individual to test insulin and vitamin D3 levels using particular ELISA kits. In addition, by colorimetric test, serum was used to estimate total cholesterol, triglyceride, and high-density lipoprotein cholesterol. Aside from that, fasting serum glucose levels were measured (FSG). Results: Fasting serum glucose (FSG), homeostatic model assessment-insulin resistance (HOMA-IR), total cholesterol, and triglycerides, all of these values were significantly elevated in people with diabetes as compared to controls (p-value <0.05) when the serum level of vitamin D was markedly low. In contrast, insulin and high-density lipoprotein values had decreased significantly in the diabetic population compared to controls (p-value <0.05) and were not correlated to vitamin D levels. Conclusions: Diabetes patients had higher FSG, HOMA-IR, hemoglobin A1c (HbA1c), fasting insulin, triglycerides, total cholesterol to high-density lipoprotein cholesterol ratios (TC: HDL-C), triglyceride to high-density lipoprotein cholesterol ratios (TG: HDL-C), and low-density lipoprotein cholesterol to high-density lipoprotein cholesterol ratios (LDL-C: HDL). In obese diabetic individuals, vitamin D levels had a significant impact on total cholesterol, LDL-C, and the TC:HDL-C ratio.
Background: More than half of the individuals diagnosed with coronavirus disease 2019 (COVID-19) have been found to have high levels of interleukin (IL)-6. A recent report showed that more elevated serum IL-6 level predicts COVID-19 disease severity and patients’ clinical outcomes. Therefore, this study aimed to compare the serum levels of α1-antitrypsin (AAT), IL-1β, and IL-6 between COVID-19 patients and healthy individuals. Methods: During the data collection phase, 90 individuals were enrolled, 45 healthy controls, and 45 patients confirmed with COVID-19 using reverse transcription-quantitative PCR (RT-qPCR) at a specialized isolation hospital in Baghdad between November 2021 and March 2022. In this cross-sectional research, venous blood samples were taken, and serum was isolated and stored for quantitative ELISA measurements of AAT, IL-1β, and IL-6 (ELISA). IBM SPSS version 24 was used to analyze the data. Results: This study revealed a significant increase in the serum levels of AAT, IL-1β, and IL-6 in the COVID-19 patients' group compared to the healthy control group with p-values < 0.001 for each of these markers. Conclusions: AAT concentrations were higher during COVID-19; this elevation is essential during infection. IL-1β and IL-6 levels were also elevated during the infection period; however, dysregulated high levels may lead to cytokine release syndrome. Therefore, these three biomarkers can be regarded as diagnostically crucial parameters.
Background: Ankylosing spondylitis (AS) is a progressive, chronic inflammatory illness with an unclear etiology that explicitly targets the vertebral column, peripheral joints, and extraarticular tissues. The purpose of this research was to investigate if the existence of single nucleotide polymorphisms (SNPs) in the promoter region of the tumor necrosis factor-alpha (TNF-α) gene at positions -1031T/C (rs199964), -857C/T (rs1799724) and -806C/T (rs4248158) in a sample of Iraqi AS patients could influence the patients' outcomes with etanercept. Methods: Sixty patients with established AS receiving only etanercept were selected to enroll in this study, with a mean age of 40.75±8.67 years; 51 patients were male. Patients were classed as "responders" if they obtained a Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) 50 clinical response and as "non-responders" if they did not achieve a BASDAI 50 clinical improvement after at least six months of treatment. After polymerase chain reaction (PCR) product amplification of the purified blood DNA, the promoter region of TNF-α gene SNPs was established by Sanger sequencing. Results: This research found a significant difference in the TT genotype of rs1799964, P = 0.02, in the responder group, in contrast to the TC genotype of rs1799964, which was significantly more frequent in the non-responder group, P = 0.01. The wild TT genotype of rs1799964 seemed to enhance the probability of being a responder. Nevertheless, the heterozygote TC genotype of rs1799964 showed a negative and significant correlation for responsiveness to etanercept. Conclusion: The TT genotype of rs1799964 is associated with a higher likelihood of responding to ETN, suggesting that it is a valuable diagnostic for predicting response in Iraqi AS patients.
