Correlation of Anemia Due to Poor Iron Status With Obesity at King Fahad Medical City, Riyadh, Saudi Arabia.

Background Saudi Arabia has a high prevalence of chronic diseases such as obesity. Moreover, iron deficiency anemia (IDA) in developing countries is the most prevalent type of anemia. This study aims to assess the correlation between anemia related to poor iron status and obesity. Methods A cross-sectional observational study was conducted at the obesity center in King Fahad Medical City, Saudi Arabia, from April to September 2020. Two hundred and forty participants were needed to be included in the study. The data was gathered by utilizing a designed data collection form. Socio-demographic data, weight and height, questions related to the history of anemia, and gynecological data (for females) were collected. The data was analyzed using SPSS (Statistical Package for Social Science) version 28.0. Descriptive statistics were used to present numerical and categorical data and a Chi-square test was conducted to assess the correlation between categorical variables. Informed written consent was obtained from all participants and ethical approval was obtained from the Ethical Board Committee in King Fahad Medical City. Results The study included 240 participants. Two-thirds of the study population are females (64.6%), 66.7% are married, and 65.8% have obesity. Almost one-half of the study population (46%, N=128) was diagnosed with IDA with malnourishment being the most common reason for IDA (88.2%). The results indicated a correlation between obesity and the prevalence of IDA. The prevalence of IDA among participants with obesity (60.4%) was significantly higher compared to non-obese participants (39.5%), p=0.002. The study found that females and underweight individuals have a higher prevalence of IDA (p<0.001). Conclusion Results of the present study suggest that obesity could be associated with a risk of IDA. In addition, Saudi women could be more prone to IDA than men. Further prospective controlled studies among diverse populations in Saudi Arabia including laboratory assessment of inflammatory markers and iron status are required to better understand the correlation between obesity and IDA.

Comparison of laboratory biomarkers for the prediction of in-hospital mortality and severity of acute pulmonary embolism: A multi-center study.

OBJECTIVES: To assess the specificity and sensitivity of prognostic biomarkers in individuals diagnosed with acute pulmonary embolism (PE). METHODS: This study retrospectively enrolled 162 patients from the 741 patients who were hospitalized with acute PE and diagnosed using pulmonary computed tomography (CT) angiogram at 5 hospitals in Saudi Arabia between January 2015 and December 2019. Pulmonary embolism patients classified into survivor and non-survivor groups. Neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and red cell distribution width (RDW) were all recorded and were compared between the groups. The evaluation of mortality prediction, sensitivity, and specificity was carried out by employing receiver operating characteristic curves. RESULTS: The variables NLR and RDW exhibited a statistically significant correlation with increased mortality and disease severity. A total of 8 patients among the 162 patients died. At the cut-off value of 5.5, NLR was showed an association with all-cause mortality, demonstrating a sensitivity of 75% and a specificity of 82%. At the cut-off value of 18.15, RDW was found to be significantly associated with all-cause mortality, displaying a sensitivity of 63% and a specificity of 88%. CONCLUSION: Multiple parameters have been implicated in the mortality and severity of PE. Our study revealed a statistically significant association between NLR, RDW, and PE mortality. These tests are easily accessible and may provide insights into the mortality associated with PE.

COVID-19 in Saudi Patients With Sickle Cell Disease: A Retrospective Multi-Center Study.

Background The prevalence of sickle cell disease (SCD) within Saudi Arabia is relatively high, with an estimated 145/10,000 cases. There is an urgent need for researching many aspects of the Coronavirus disease of 2019 (COVID-19) due to the widespread of the virus among SCD patients in Saudi Arabia. The aim of this study is to determine how COVID-19 affects SCD patients in order to reach the best strategy for their management protocols. Methods This is a retrospective chart review study from a multi-center in Saudi Arabia that evaluated a total of 33 patients with sickle cell anemia/disease who were confirmed to have COVID-19. The diagnosis of COVID-19 was confirmed by using the reverse transcription-polymerase chain reaction (RT-PCR) tests based on the nasopharyngeal swabs of the included patients. Results The mean age of patients was 10.75+9.11 years, and nearly all patients (n= 32; 96.9%) were Saudi, and 48.4% of them were females. Twenty-two patients were admitted (59.5%); the main reasons for admission included vaso-occlusive crisis (VOC) only (n= 6; 27.3%), fever (n= 6; 27.3%), acute chest syndrome (n= 5; 22.7%), and VOC combined with other conditions (n= 4; 18.2%). During hospitalization, 54.1% of the patients received at least one medication, while antibiotics (54.1%), analgesia (32.4%), anticoagulants (16.2%), and steroids (16.2%) were the most commonly administered drugs. The mean length of hospitalization was 7.6±4.5 days, with only one patient (2.7%) requiring intensive care unit admission and assisted ventilation. Conclusion The overall prognosis was good since only one patient has passed away, while all others recovered and, subsequently, were discharged. Manifestations, laboratory investigations, and management modalities should be utilized promptly to enhance the prognosis and obtain better outcomes.

Multiple Autoimmune Syndrome With Alopecia Universalis and Immune Thrombocytopenic Purpura.

Multiple autoimmune syndrome (MAS) is a condition characterized by three or more autoimmune disorders in the same individual. The development of MAS involves genetic, immunological, and infectious factors. Here we report a case of a 40-year-old man who presented with four autoimmune diseases, namely autoimmune hypothyroidism, alopecia universalis, celiac disease, and immune thrombocytopenic purpura (ITP), which leads to a diagnosis of MAS. However, the patient does not fit in any category of MAS classification. In addition to the need for continued surveillance for the development of new autoimmune disease in predisposed patients, this case report suggests an additional fourth category of the classification of MAS that includes autoimmune hypothyroidism, alopecia universalis, celiac disease, and ITP.

Vitamin B12 Deficiency Presenting With Microangiopathic Hemolytic Anemia.

Vitamin B12 has essential roles in DNA synthesis, red blood cell development, and neurologic functions. Vitamin B12 deficiency is relatively common, particularly in people aged over 60 years. Among hematological disturbances, microangiopathic hemolytic anemia with thrombocytopenia or so-called pseudo-thrombotic microangiopathy (pseudo-TMA) is a particularly rare but significant clinical complication in patients with vitamin B12 deficiency. We herein describe a case of an elderly patient with pseudo-TMA whose lack of vitamin B12 was misdiagnosed as thrombotic thrombocytopenic purpura (TTP). The patient was admitted as a case of pancytopenia with a hemolytic picture. The initial impression was TTP versus acute promyelocytic leukemia M3. After examination of laboratory tests and bone marrow examination, we deduced that the patient had a B12 deficiency. The condition of the patient improved with B12 replacement. This report should remind physicians to widen their differential diagnoses when patients present with microangiopathic hemolysis or in patients who are not responsive to standard treatments for TTP.

Depression, Anxiety, and Stress Symptoms in Patients With Beta Thalassemia Major in Almadinah Almunawwarah, Saudi Arabia.

Introduction Beta thalassemia major (BTM) is a chronic hereditary blood disorder. Patients are dependent on blood transfusion and are prone to multiple comorbidities. Depression, anxiety, and stress (DAS) can complicate their condition. No reports from Saudi Arabia to measure DAS in BTM patients. We report the prevalence of DAS symptoms in our BTM patients using the DASS-21 (Depression, Anxiety, and Stress Scale - 21 Items) test. Methods A cross-sectional study including adolescents and adults aged 14 years and above with BTM treated in Almadinah Almunawwarah and excluding patients who had bone marrow transplant or with central nervous system insults were performed. Results A total of 31 male and 31 female patients were enrolled, with a mean age of 24.32 ± 7.05 years. Depression symptoms were detected in 60 % of patients, anxiety symptoms were detected in half of the studied group, and stress symptoms were detected in 38.7% of patients. We found a significant positive correlation between DAS and DASS total score. Age below or above 18, parent's employment, patient's educational level, and status of satisfaction about medical care were statistically significant in having positive effects on scores of DAS symptoms.  Conclusions BTM patients are prone to develop psychological disorders, which can affect the course of the disease. Our results are comparable to international and Arab population studies, which have the highest reported prevalence. It is important to not ignore the psychological evaluation of patients with BTM and to refer them for proper evaluation and management.

Determining the prevalence and causes of anaemia in patients after bariatric surgery in a Saudi hospital.

OBJECTIVES: Obesity is a chronic disease with high prevalence in Saudi population. Bariatric surgery is an effective method for significant weight reduction. However, various types of nutritional deficiencies occur after weight loss surgery which increase the risk of anaemia. In this study, we aimed to determine the incidence of anaemia after bariatric surgery. METHOD: A retrospective descriptive study was conducted with 70 patients of both genders aged over 16 years. These patients underwent bariatric surgery between February 2016 and March 2018 and had completed 6 months or more of post-surgery follow-up. Anthropometric and laboratory data were obtained before and after surgery at standard time intervals. All patients were on postoperative vitamin supplements. RESULTS: Of the total study patients, 41 were women (58.57%) and 29 were men (41.42%) with a median age of 38.5 years (range, 16-65). The median follow-up time was 8 months (6-24 months). Postoperatively, 16 patients (22.9%) developed anaemia, and interestingly, all of them were women (39%). Fifteen of these sixteen patients (93.8%) had microcytic anaemia. Two of those sixteen patients (12.5%) had Roux-en-Y gastric bypass, while fourteen (87.5%) had sleeve gastrectomy. CONCLUSION: Anaemia and its related nutritional deficiencies are a common complication after bariatric surgery which exerts a major impact on health, particularly in women. Hence, a strict post-operative follow-up and appropriate supplementation are recommended to combat anaemia and its related nutritional deficiencies.

Relation between ABO blood groups and obesity in a Saudi Arabian population.

OBJECTIVES: ABO blood groups have been shown to be associated with different diseases. Very few studies have attempted to detect the association of ABO blood groups with obesity. The goal of this study is to find any potential relation between ABO blood groups and high body mass index (BMI) among a Saudi population, which may contribute to underlying genetic disorders. METHODS: A cross-sectional descriptive study was conducted using a structured questionnaire that contained general demographic data, including weight, height, type of ABO blood group and the participants' opinion, to determine the association between the ABO blood groups and obesity. RESULTS: Our study included 1171 participants, including 596 (50.9%) women. A plurality of participants' ages (47%) was between 15 and 25 years. The prevalence of obesity was 35.7% in men and 20.3% in women, while the prevalence of overweight was 30% in men and 25.3% in women. Blood group O was reported to be the most common blood group (46%), followed by blood group A (31.4%), while blood groups B and AB were found in 16.1% and 6.5% of participants, respectively. The prevalence of obesity (BMI ≥ 30) among participants based on blood group O, A, B, and AB was 13.7%, 9%, 4.8%, and 2.2%, respectively. There was no statistically significant difference between the prevalence of obesity or high BMI and ABO blood groups. CONCLUSION: Overall, our study did not show a significant relation between overweight and obesity and ABO blood groups. However, the elevation of the prevalence of overweight and obesity, mainly among the younger generations of the Saudi population, requires more awareness and educational programs.
