A need to adopt new strategies for organ donation in Saudi Arabia.

BACKGROUND: HLA matching in kidney transplantation is a major factor in long-term survival of the graft. In Saudi Arabia, most deceased donors are non-Saudi, making it difficult to achieve minimal HLA mismatches between donor and recipient. OBJECTIVE: To analyze HLA types of 200 deceased donors and compare them with the Saudi population's HLA types. MATERIALS AND METHODS: In a retrospective study analyzing HLA types of the last 398 deceased donors processed in a tertiary hospital in Riyadh, Saudi Arabia, HLA types of all donors were compared with HLA types from a control group of healthy Saudi persons. RESULTS: HLA types were significantly different between the deceased donor group and the Saudi population. In all deceased donors, zero mismatches was never achieved. The major differences in HLA types were in HLA-A*02, HLA-B*15, B*40, B*50, HLA-DRB1*14, DRB1*15, and DRB1*04. CONCLUSIONS: As most of our deceased donors are non-Saudis, it is difficult to match for HLA-A, HLA-B, and HLA-DR. HLA matching should be attempted nationwide by adopting different strategies, including typing donors centrally and distributing results to all centers, agreeing on a national point system for allocating organs from deceased donors, and making HLA matching a priority, especially for highly sensitized patients.

Prevalence and Predictive Factors of Female Sexual Dysfunction in a Sample of Saudi Women.

INTRODUCTION: Female sexual dysfunction (FSD) is a common health problem that is inadequately investigated in Saudi Arabia. AIM: To assess the prevalence and predictors of FSD in a sample of Saudi women attending the primary care and gynecology clinics. METHODS: A cross-sectional clinic-based survey involved Saudi women attending primary care and gynecology clinics in a teaching hospital in Riyadh during the period from January to June 2019. Data were collected using a structured interview questionnaire. Female sexual function has been evaluated by the Arabic version of the Female Sexual Function Index. MAIN OUTCOME MEASURES: The main outcome measure of this study was female sexual function using the Arabic version of the Female Sexual Function Index. RESULTS: 200 Saudi women were included in this study. Their age ranged from 18 to 50 years. Most of the participants (88.5%) were fairly satisfied or satisfied with their spouse's sexual ability and 120 (60%) had a risk of FSD. Participants with FSD reported the lowest scores for arousal and desire domains (3.03 ± 1.3 and 3.12 ± 1.1, respectively) followed by orgasm domain (3.48 ± 1.4). Predictive factors for risk of FSD in our participants were age greater than 40 years (P = .012), unemployment (P = .035), low/moderate family income (P = .014), dissatisfaction with the spouse's sexual ability (P = .005), and higher weight (P = .010) and height (P = .043). Only age greater than 40 years (P = .041), low family income (P = .007), and dissatisfaction with spouse's sexual ability (P = .011) sustained independent significance in a multivariate logistic regression analysis. CONCLUSION: A high prevalence of FSD was encountered in our sample of Saudi women. Desire and arousal were the most significantly affected domains followed by orgasmic problems. Age greater than 40 years, low socioeconomic level, and dissatisfaction with the spouse's sexual ability are the most significant predictors. Madbouly K, Al-Anazi M, Al-Anazi H, et al.

Chances of finding an HLA-matched sibling: The Saudi experience.

Hematopoietic cell transplantation (HCT) remains the fundamental procedure to treat many diseases. Its success depends greatly on the degree of HLA matching between donor and recipient. Although the number of successful HCT procedures carried out worldwide increases every year, many patients remain unable to receive this treatment because of the difficulty of finding an HLA-matching donor. In our center, we identified the HLA types for all HCT candidates and their siblings in an attempt to determine the chance of finding a full HLA-matching sibling. Overall, 60% of patients had a chance of finding an HLA-matching sibling. The chance of finding a matching sibling was 43% in patients aged birth to 5 years, compared with 68% in those aged 20+ years. In our Saudi population, patients in need of HCT have a greater chance of finding an HLA-matching sibling than is reported in most Western countries. This is mainly because of the larger number of siblings in most Saudi families. Younger children requiring HCT have a lesser chance of finding an HLA-matching sibling. Our data demonstrate that even in a country with relatively large families, it is still essential to consider alternative donor strategies, such as adult unrelated donors, unrelated umbilical cord blood units, and haploidentical donors.

HLA-C polymorphisms in two cohorts of donors for bone marrow transplantation.

The typing for HLA-C in transplantation was rather neglected in the past. However, several recent studies have emphasized its role in transplantation and its association with the outcome. Serological typing of HLA-C could identify only a limited number of HLA-C antigens, resulting in a number of HLA-C blanks. This was mainly due to the low expression of surface HLA-C and the small number of available specific anti-sera. Performing molecular methods has identified new HLA-C alleles and filled the blank of most serological typed antigens. In this study, we compared serological and molecular typing of HLA-C in two cohorts of healthy Saudis. Our serological typing method identified HLA-C1-7 with different frequencies, 23.5% of the alleles were not identified and thus defined as blank. Using the SSP molecular method, all samples were typed and all alleles were defined. Both methods showed that C∗07 and C∗06 have the highest frequency in the Saudi population. Our study emphasizes the importance of molecular methods in identifying all possible HLA-C alleles.
