Vitamin D level, lipid profile, and vitamin D receptor and transporter gene variants in sickle cell disease patients from Kurdistan of Iraq.

ABSTRACT:

Introduction

Sickle cell disease (SCD) patients are susceptible to the development of vitamin D deficiency (VDD). Vitamin D through binding to vitamin D receptor (VDR) exerts its function and affects gene transcription in target tissues. VDR gene variants affect bone mineral density.

Methods

In a case-control study, 101 SCD patients including 61 sickle cell anemia (SCA), 39 S/β-thalassemia, and 1 HbS/HbD (SD) along with 110 healthy individuals from Kurdistan of Iraq were studied. The lipid profile, vitamin D level, FokI, and TaqI variants of VDR and group-specific component (GC) were detected using the standard enzymatic method, the immunodiagnostic systems limited EIA kit and PCR-RFLP methods, respectively.

Results

Around 93% and 82% of SCA and S/β-thalassemia patients, respectively, had VDD compared to 83% of healthy individuals. Severe VDD (<10 ng/ml) was detected in 78.7% of patients with HbSS. Plasma levels of total cholesterol, HDL-C, and LDL-C in SCD patients were significantly lower compared to controls. Vitamin D levels were negatively correlated to TG and positively correlated to total cholesterol and HDL-C. The frequencies of the C allele of FokI were 81.7% (p = 0.003), 80.3% (p = 0.034), and 84.6% (p = 0.011) in all SCD, SCA, and S/β-thalassemia patients, respectively, compared to 69.1% in controls. However, no significant difference was detected comparing the frequencies of VDR TaqI and GC polymorphisms between SCD patients and controls.

Conclusion

In the present study, we found hypocholesterolemia, high prevalence of VDR FokI C allele, and low vitamin D levels among children and adults with SCD from Kurdistan of Iraq.

Project description:Unsafe abortion is a major contributor to maternal morbidity and mortality in countries where induced abortion is restricted. In Kurdistan Region of Iraq, induced abortion is strictly forbidden except for life-threatening situations, increasing the risk of seeking unsafe abortions. Attitudes among healthcare professionals who directly encounter cases and consequences of induced abortion can be studied to improve women's access to safe abortion. This study aimed to examine attitudes towards induced abortion among gynecologists in Kurdistan Region of Iraq. This cross-sectional facility-based study was conducted in the first quarter of 2022 in Kurdistan Region of Iraq in the cities of Erbil, Sulaymaniyah, and Duhok. Convenient sampling was used to invite 330 gynecologists to participate, with 171 ultimately completing the questionnaire, giving a response rate of 53%. Questionaries using the Taylor and Whitehead abortion attitude scale were sent in person or digitally. The data was then analyzed using Chi-square and Fisher's exact tests to determine the independence of attitudes and associations between attitudes and sociodemographic factors. Among 171 gynecologists, 25% of the gynecologists agreed that induced abortion is unacceptable under any circumstances. Most (71%) disagreed that a woman has the right to choose to have an induced abortion. Around 51% considered induced abortion murder, and 41% agreed that induced abortion goes against all morals. Around 57% disagreed with the legalization of induced abortion, while 43% agreed. Gynecologists who were unmarried (P = 0.025), under the age of 40 (P = 0.044), and with less than 10 years of clinical experience (P = 0.043) were more likely to support the legalization of induced abortion in Kurdistan Region. None of the variables was found to be independently associated with attitudes towards abortion legalization. Despite some younger gynecologists having more favorable attitudes towards induced abortion, most gynecologists in Kurdistan Region had less favorable views. Most gynecologists were willing to provide post-abortion care regardless of their legal status. We recommend conducting more studies to investigate the consequences of current abortion legislation among women in need of induced abortion in Kurdistan Region of Iraq.

Project description:BACKGROUND: Violence against women is a worldwide problem and serious human rights abuse that occurs among all social, cultural, economic and religious groups. There is a paucity of research on intimate partner violence against women in Iraq, particularly in the Kurdistan region. This study assessed the prevalence of emotional, physical and sexual intimate partner violence against women and the impact of physical violence in Erbil, the main city of the Iraqi Kurdistan region. METHODS: A cross-sectional study was carried out on a convenience sample of 800 Kurdish ever married women. Women (aged 16 to 65 years) attending two public hospitals in Erbil city for reproductive health problems were included in the study. The study was conducted between 1st of October 2009 and 30th of March 2011. Each woman was seen only once. Intimate partner violence was assessed by administering a modified version of the World Health Organization's domestic violence questionnaire through direct interview by a female doctor. Prevalence of intimate partner violence was assessed by timing (lifetime or past year), frequency (once, 2-5 times, > 5 times), and type (emotional, physical, and sexual violence). Descriptive statistical analysis was conducted with calculation of frequencies and percentages of women who reported different types, severities and impact of intimate partner violence. RESULTS: The prevalence of the overall lifetime and the overall past year intimate partner violence against women was 58.6% and 45.3%, respectively. The proportions of women experienced at least one form of lifetime intimate partner violence were: 52.6% for emotional abuse; 38.9% for physical violence; and 21.1% for sexual violence, while 43.3%, 15.1%, and 12.1% of women experienced at least one form of past year emotional, physical and sexual violence, respectively. Among those with lifetime physical violence, 11.6% were subjected to more serious injuries like stab wound, broken teeth or broken bones. CONCLUSIONS: There is a high prevalence of intimate partner violence, in particular emotional abuse behavior, against the women attending hospitals in Erbil. Physical violence is also a significant problem particularly in terms of its consequences.
