Abstract
Objectives To evaluate the hypothesis that human leukocyte antigens (HLAs) confer susceptibility to schizophrenic disorders, by assessing their contribution to the risk of schizophrenia in a Yemeni population. Methods The researchers approached patients who had been diagnosed with schizophrenia at Al-Amal Hospital for Psychiatric Diseases, Sana'a. Controls were drawn randomly from the general population. The HLA class II alleles of the participants were examined. The genotypes of the HLA-DQB1 and HLA-DRB1 alleles were determined by polymerase chain reaction using sequence-specific primers. Results The subjects comprised 110 patients with schizophrenia, matched by an equal number of controls. The prevalence of HLA-DRB1*04 was significantly higher among patients than among controls (7.3% vs. 0.0%; p =0.003), as was HLA-DRB1*07 (62.7% vs. 17.3%, odds ratio (OR) = 8.1, 95% CI: 4.3-15.1; p < 0.001). HLA-DRBI*14 was significantly less prevalent among patients (0.9% vs. 11.8%, OR = 0.06, 95% CI: 0.01-0.50, χ2 = 10.9; p < 0.001). HLA-DQB1*07 was the most common allele discovered in schizophrenia patients and was found to have a much higher incidence in patients than the control group (22.7% vs. 4.5%, OR = 6.2, 95%CI: 2.3-16.8, χ2 = 15.4; p < 0.001). Conclusions The HLA-DQB1 and HLA-DRB1 gene loci are linked to schizophrenia in the Yemeni population, according to the current study's evidence.

Abstract
Since the discovery of human leukocyte antigens (HLAs), the function of major histocompatibility complex (MHC) gene families in a wide range of diseases have been the subject of research for decades. In particular, the associations of autoimmune disorders to allelic variants and candidate genes encoding the MHC are well documented. However, despite decades of research, the knowledge of MHC associations with human disease susceptibility have been predominantly studied in European origin, with limited understanding in different populations and ethnic groups. This is particularly evident in countries and ethnic populations of the Arabian Peninsula. Human MHC haplotypes, and its association with diseases, of the variable ethnic groups of this region are poorly studied. This review compiled published manuscripts that have reported a list of autoimmune diseases (insulin-dependent diabetes mellitus, systemic lupus erythematosus, myasthenia gravis, rheumatoid arthritis, psoriasis vulgaris, and multiple sclerosis) associated with MHC class I and class II in the populations of the Arabian Peninsula, specifically Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, the United Arab Emirates, and Yemen. Data available was compared with other three ethnic groups, namely Caucasians, Asians, and Africans. The limited data available in the public domain on the association between MHC gene and autoimmune diseases highlight the challenges in the Middle Eastern region.

Abstract
Objectives: To investigate the role of Human leukocyte antigen (HLA) Class II DRB1 in susceptibility to psoriasis in Iraqi patients. Methods: A cross-sectional comparative study including 40 patients with psoriasis attending the Department of Dermatology, Al-Kindy teaching hospital in Baghdad, Iraq, between September 2013-2015. Patient selection was carried out by the dermatologists. Ninety healthy individuals were included in the study. Human leukocyte antigen genotyping was carried out by the sequence specific oligonucleotide (SSO) method using Auto LiPA 48 (Innogenetics, Belgium) in the HLA typing research unit of the Al-Kindy College of Medicine, Baghdad, Iraq. Results: There is an increased frequency of HLA-DRB1*0102, *0306 in psoriatic patients with psoriasis p-values=0.001, confidence interval(CI)=2.492-37.487 and odds ratio(OR)=9.666. Human leukocyte antigen-DRB1*1101 is significantly associated with plaque-type psoriasis with p=0.0434, CI=1.04-1.69, and OR=4.2. Human leukocyte antigen-DRB1*0102 is significantly associated with other types of psoriasis with p=0.018, CI=0.0223-0.701, and OR=0.125. Conclusion: Human leukocyte antigen-DRB1*0102 and *0306 are significantly associated with psoriasis. Human leukocyte antigen-DRB1*1101 is significantly associated with plaque-type psoriasis. Human leukocyte antigen-DRB1*0102 is significantly associated with other types of psoriasis rather than plaque-type psoriasis.

Abstract
Multiple autoimmune syndrome (MAS) is a rare condition, in which at least three well-defined autoimmune diseases co-occur in a single patient. Although the pathogenesis of MAS remains poorly understood, genetic, immunological, hormonal, and environmental factors may all play a role. Although three classic subtypes of MAS are well known, several cases that could not be placed into any of these three categories have recently been reported. To the best of our knowledge, the co-existence of psoriasis, vitiligo, and Crohn's disease has been reported in only one patient, who had a total of five autoimmune diseases (alopecia areata and oral lichen planus in addition to the three conditions mentioned). We herein describe a rare case of MAS presenting with psoriasis, vitiligo, and Crohn's disease, and suggest that tumor necrosis factor-α may be associated with the pathogenesis of all three conditions.

Abstract
Autoimmune diseases are known to have association with each other but it is very rare to see multiple autoimmune diseases in one patient. The combination of at least three autoimmune diseases in the same patient is referred to as multiple autoimmune syndrome. The case we are reporting features multiple autoimmune syndrome with five different conditions. The patient had type 1 diabetes mellitus, autoimmune hemolytic anemia, systemic lupus erythematosus, vitiligo, and psoriasis. Psoriasis has rarely been reported previously under the spectrum of autoimmune syndrome. Although the relationship of autoimmune conditions with each other has been explored in the past, this case adds yet another dimension to the unique evolution of autoimmune pathologies. The patient presented with a combination of five autoimmune diseases, which makes it consistent type three multiple autoimmune syndromes with the addition of psoriasis. The current case is unique in this aspect that the combination of these five autoimmune disorders has never been reported in the past.
