RESUMEN
OBJECTIVES: To evaluate the knowledge and awareness of stroke in adult population in Taif, Kingdom of Saudi Arabia and to address the association between several sociodemographic variables of participants and their knowledge regarding stroke. METHODS: A cross-sectional study was conducted among adult residents in Taif, Kingdom of Saudi Arabia, during the period of December, 2020 to February, 2021 using an online questionnaire. RESULTS: Our study included 3456 participants (43.6% males, 56.4% females). Analysis showed that 61.7% of the participants were aware of stroke. Participants who were 15-39 years-old had good knowledge. Male participants had better knowledge than females. The most identified risk factor was 'unhealthy lifestyle' (84.5%) and the least identified one was 'epilepsy' (34.8%). The most identified symptom was 'slurred speech' (57.5%), and the least identified one was 'dizziness' (36.2%). Approximately 86.6% of the participants agreed that stroke was a medical emergency. A total of 41.5% of the participants agreed that stroke was treatable and 42.6% agreed that stroke was a preventable disease. CONCLUSION: Although the participants recognize that stroke is a medical emergency and that early intervention is crucial, the obtained results show that there is a large gap in the knowledge of the warning signs and symptoms of stroke. Increasing community awareness about these warnings may affect how quickly the patient is treated.

ABSTRACT: Gastroesophageal reflux disease (GERD) is one of the most common problems encountered in outpatient general medicine and gastroenterology clinics. GERD may present with classic esophageal symptoms, extraesophageal symptoms, or mixed symptoms. The diagnosis and treatment of GERD are challenging due to the variety of symptoms and multifactorial pathophysiology. Since there is no consensus on the diagnosis and treatment of GERD in Saudi Arabia, the Saudi Gastroenterology Association established an expert group to formulate a consensus on the clinical care pathway for the diagnosis and treatment of GERD to update health-care providers in Saudi Arabia. The expert group reviewed the literature including recently published international guidelines, clinical trials, and expert opinion and conducted virtual and in-person meetings. A total of 22 statements on the definition, diagnosis, and treatment of GERD were formulated, and three algorithms for the clinical care of GERD were developed with a detailed description for each step. The expert group endorsed the new definition of GERD, the practical principles of interpretation of the diagnostic GERD evaluation, and the practical guidance for GERD treatment including medical, surgical, and endoscopic therapy. The expert group recommends further studies to investigate local data on the diagnosis and treatment of GERD.
RESUMEN
Background: Patients with uncontrolled type 2 diabetes mellitus (T2DM) require close follow-up, support, and education to achieve glycemic control, especially during the initiation or intensification of insulin therapy and self-care management. This study aimed to describe and evaluate the impact of implementing a hybrid model of in-person and telemedicine care and education on glycemic control for patients with uncontrolled T2DM (hemoglobin A1c [HbA1c] ≥9%) during the coronavirus disease pandemic. Methods: This prospective multicenter-cohort pre-/post-intervention study was conducted on patients with uncontrolled T2DM. This study included three chronic illness centers affiliated with the Family and Community Medicine Department at Prince Sultan Military Medical City in Riyadh, Saudi Arabia. A hybrid model of in-person (onsite) and telemedicine care and education was developed. This involved implementing initial in-person care at the physicians' clinic and initial in-person education at the diabetes education clinic, followed by telemedicine services of tele-follow-ups, support, and education for an average 4-month follow-up period. Results: Of the enrolled 181 patients, more than half of the participants were women (n = 103, 56.9%). The mean age of participants (standard deviation) was 58.64 ± 11.23 years and the mean duration of diabetes mellitus was 13.80 ± 8.55 years. The majority of the patients (n = 144; 79.6%) were on insulin therapy. Overall, in all three centers, the hybrid model had significantly reduced HbA1c from 10.47 ± 1.23% to 7.87 ± 1.59% (mean difference of reduction 2.59% [95% confidence interval (CI) = 2.34-2.85%], p < 0.001). At the level of each center, HbA1c was reduced significantly with mean differences of 3.17% (95% CI = 2.81-3.53%), 2.49% (95% CI = 1.92-3.06%), and 2.16% (95% CI = 1.76-2.57%) at centers A, B, and C, respectively (all p < 0.001). Conclusion: The findings showed that the hybrid model of in-person and telemedicine care and education effectively managed uncontrolled T2DM. Consequently, the role of telemedicine in diabetes management could be further expanded as part of routine diabetes care in primary settings to achieve better glycemic control and minimize nonessential in-person visits when appropriate.
RESUMEN
INTRODUCTION: The Ministry of Health in Saudi Arabia has announced a plan to eradicate hepatitis C virus (HCV) infection. This study sought to evaluate the knowledge levels and testing rate among the general population of Saudi Arabia. METHODS: A cross-sectional study was conducted using data collected from an online, self-administered survey. Multivariable analysis was conducted using multiple binary logistic regression models to identify factors associated with low knowledge levels as well as predictors of HCV testing. RESULTS: A total of 689 participants completed the survey. While most participants (88%) have heard of HCV infection, less than half (47.3%) understood that HCV is curable with medications. More than half of the participants (53.7%) have low knowledge about HCV infection. Testing for HCV was reported by 123 respondents (17.8%), and the odds of testing for HCV were significantly lower among residents of the Makkah region (OR = 0.59 [95% CI: 0.36-0.97]) and those with low knowledge level (OR = 0.47 [95% CI: 0.29-0.74]). HCV diagnosis was reported by nine respondents (1.3%), of whom only four reported receiving treatment (44%). CONCLUSIONS: Our study indicates inadequate knowledge levels and relatively low testing rate. These findings underscore the need for national awareness campaigns and more effective strategies for HCV screening.

Background Dry eye syndrome (DES), also known as keratoconjunctivitis sicca (KCS), is a common cause of patient's visits to the ophthalmologist. It is characterized by a defect in the tear film homeostasis, symptoms of ocular discomfort, and visual disturbance. Also, it increases the risk of ocular surface damage if complicated by tear film hyperosmolarity and ocular surface inflammation. The present study aims to measure awareness about dry eye disease and the risk factors among the Eastern region population in Saudi Arabia via an online questionnaire. Methods This is a cross-sectional community-based study conducted in Saudi Arabia that assessed knowledge and awareness of dry eye among the eastern province population using a self-administered online questionnaire. The minimum sample size was 385 adults. Statistical analysis was performed using SPSS software, version 21.0 (IBM Corp., Armonk, NY), and participants' overall awareness level was evaluated based on correct answers. Results In this study, a total of 522 participants fulfilling the inclusion criteria completed the study questionnaire. Participants ranged from 18 to 65 years, with a mean age of 27.2 ± 14.6 years old. Females represented a higher percentage of the sample, 341 (65.3%). Public awareness regarding dry eye diseases in the Eastern region, Saudi Arabia of 149 participants (28.5%) is overall a good awareness level while 373 (71.5%) of them had poor awareness. Conclusion Participants showed unsatisfactory results in awareness of risk factors of dry eye symptoms, where the most reported causes were prolonged concentration while using electronic devices, climatic factors, and lacrimal gland disorders.
RESUMEN
Background: Although estrogen (ERα/ERß), progesterone (PGR), and androgen (AR) receptors are pathologically altered in colorectal cancer (CRC), their simultaneous expression within the same cohort of patients was not previously measured. Methods: ERα/ERß/PGR/AR proteins were measured in archived paired normal and malignant colon specimens (n =120 patients) by immunohistochemistry, and results were analyzed by gender, age (≤50 vs. ≥60 years), clinical stages (early-stage I/II vs. late-stage III/IV), and anatomical location (right; RSCs vs. left; LSCs). Effects of 17ß-estradiol (E2), progesterone (P4), and testosterone alone or combined with the specific blockers of ERα (MPP dihydrochloride), ERß (PHTPP), PGR (mifepristone), and AR (bicalutamide) on cell cycle and apoptosis were also measured in the SW480 male and HT29 female CRC cell lines. Results: ERα and AR proteins increased, whilst ERß and PGR declined markedly in malignant specimens. Moreover, male neoplastic tissues showed highest AR expression, whilst ERß and PGR weakest alongside ERα strongest expression was seen in cancerous tissues from women aged ≥60 years. Late-stage neoplasms also revealed maximal alterations in the expression of sex steroid receptors. By tumor location, LSCs disclosed significant elevations in ERα with marked declines in PGR compared with RSCs, and ERα strongest alongside PGR weakest expression was detected in advanced LSCs from women aged ≥60 years. Late-stage LSCs from females aged ≥60 years also showed weakest ERß and strongest AR expression. In contrast, male RSC and LSC tissues exhibited equal ERß and AR expression in all clinical stages. ERα and AR proteins also correlated positively, whereas ERß and PGR inversely, with tumor characteristics. Concomitantly, E2 and P4 monotherapies triggered cell cycle arrest and apoptosis in the SW480 and HT29 cells, and while pre-treatment with ERα-blocker enhanced the effects of E2, ERß-blocker and PGR-blocker suppressed the E2 and P4 anti-cancer actions, respectively. In contrast, treatment with the AR-blocker induced apoptosis, whilst co-treatment with testosterone hindered the effects. Conclusions: This study advocates that protein expression of sex steroid receptors in malignant tissues could represent prognostic markers, as well as hormonal therapy could provide an alternative strategy against CRC, and their efficacies could be dependent on gender, clinical stage, and tumor location.

Infancy has been proven as the best time to improve health outcomes for the later stage of life. The composition of human breast milk has evolved over millennia to support and maintain the infant's life during the early years of life. To achieve life-sustaining effects, human breast milk is packed with fats, proteins, carbohydrates, and a wide range of bioactive compounds such as immunoglobulins, lactoferrin, and cytokines. The immunological compounds in breast milk have been shown to curtail gastrointestinal tract infections, respiratory tract infections, hospital admissions, acute otitis media, allergic reactions, and urinary tract infections. Although breastfeeding causes newborns to gain less weight at the beginning of their lives than formula milk does, breast milk improves body composition by low adiposity. A higher adipose deposition in infants is linked with an increased risk of child obesity in the future. Due to significant health benefits, the World Health Organization (WHO) recommends initiating breastfeeding within one hour after birth and continuing for at least six months. Breastfeeding has emerged as a superior source of nutrition that can promote healthy physiological and cognitive development and protect against disease challenges in low birthweight infants. This review summarizes potential evidence that highlights the potential health impact of breast milk in low birthweight infants.
RESUMEN
Cancer is a universal health issue, and many anticancer therapeutic drugs have been isolated from natural products. This study analyzed the cytotoxic and apoptotic activity of Plectranthus amboinicus leaf hexane (PALH) extract in MDA-MB-231 (median inhibitory concentration [IC50] = 39.26 µg/mL) and MCF7 (IC50 = 89.05 µg/mL) breast cancer cell lines. Cells appeared rounded and shrunken, indicating morphological changes due to apoptosis induction. The primary constituent of PALH was phenol, 5-methyl-2-(1-methylethyl) (44%). PALH extract treatment increased the percentage of late apoptotic cells in the MDA-MB231 cell line (58% ± 1.5% at 200 µg/mL) compared to the control group, as evidenced by the activated caspase-3 and caspase-7 identified and captured by fluorescence microscopy. The relative migration rate in MDA-MB-231 cells treated with 10 µg/mL of PALH extract for 48 h was significantly lower compared to the control group. Analysis of acute (2000 mg/kg/BW) and subacute (250 and 500 mg/kg/BW) toxicity of PALH extract in mice showed no mortality or adverse effects in the kidney and liver histology compared to the control group. PALH extract can be considered nontoxic as it does not cause any adverse changes and so can be proposed as a potential breast anticancer agent.

Background The COVID-19 pandemic is one of the largest global healthcare crises in nearly a century. To face this global health emergency, health institutions have had to readjust their functioning while ensuring the continuity of care and protecting medical staff and patients. Our aim in this study was to assess the consequences of the COVID-19 outbreak on family medicine and its practice in Saudi Arabia. Methods This cross-sectional study was conducted during the period from June 30, 2020, to July 20, 2020, by posting an online survey on social media platforms (WhatsApp and Twitter) and emailing physicians individually to collect data on the impact of the COVID-19 pandemic on family medicine and primary care practices during the period of lockdown in Saudi Arabia. Results A total of 382 primary healthcare (PHC) providers participated in the study (males: 213 (55.8%); females: 169 (44.2%)). The mean age and standard deviation of the population were 38.27±7.46. Most participants were from governmental health sectors. Participants revealed that they have a good level of knowledge regarding COVID-19. However, they indicated confusion regarding the knowledge due to changing recommendations or multiple-source information. Only 57.3% of respondents received relevant training on the use of personal protective equipment (PPE). The most frequently used PPE were surgical masks (100%) and gloves (98.4%). The highly protective N95 masks were used by only 55.7%. Many health care workers indicated a high rate of stress and anxiety about the COVID-19 pandemic. Data obtained are suggestive that there was a reduction in outpatient visits and a reduction in consultation time. Canceled physical examinations of the patients during the consultation were encountered most of the time. There was no shortage of medications, nasopharyngeal swabs, or sanitizers. However, an occasional lack of PPEs occurred. 64.4% of the respondents used online consultations with their patients. A shortage of health care workers during the pandemic in family medicine clinics was encountered by 63.3% of the participants. Conclusion Family medicine practices are adversely affected by pandemics and lockdowns following them. It has been reported that COVID-19 interferes with preventive, chronic, and acute care visits and increases mental health visits. Outpatient visits have also decreased as well as the amount of time spent in consultations. In addition, the transition from in-person clinics to telemedicine has happened. Perhaps these changes will delay the diagnosis and prescription refills.
RESUMEN
The Severe Acute Respiratory Syndrome-related Coronavirus 2 (COVID-19 or SARS-CoV-2) epidemic is professed as world disaster producing a worrying increasing mortality, particularly amongst vulnerable humans worldwide. Whether COVID-19 has a strong ability for acceptable genetic flexibility that amended for breaking immune responses quickly, it is critical to understand the adaptation mechanism between viruses and hosts that allows individuals to follow viral development. This can contribute to finding the appropriate treatment to combat the epidemic. However, the present information about viral adaptation mechanisms in hosts is still insufficient, and future investigations may reveal the unknown. Mutations and genetic variations are naturally occurring; however, the current knowledge about their mechanism and pathways still has many secrets. The present review also provides insights into the immune system, immunological memory, and the development of the COVID-19 vaccine. Other fighting methods against COVID-19 are also highlighted. The potential of antibodies, natural metabolites, and current suggest vaccines were applied to the face of this new threat.

Fungal infections of the paranasal cavity are among the most widely spread illnesses nowadays. The aim of the current study was to estimate the effectiveness of an in situ gel loaded with voriconazoleâclove oil nano-transferosomes (VRC-CO-NT) in enhancing the activity of voriconazole against Aspergillus flavus, which causes rhinosinusitis. The nephrotoxic side effects of voriconazole may be reduced through the incorporation of the clove oil, which has antioxidant activity that protects tissue. The BoxâBehnken design was applied to formulate the VRC-CO-NT. The particle size, entrapment efficiency, antifungal inhibition zone, and serum creatinine concentration were considered dependent variables, and the soybean lecithin, VRC, and CO concentrations were considered independent ones. The final optimized formulation was loaded into a deacetylated gellan gum base and evaluated for its gelation, rheological properties, drug release profile, permeation capabilities, and in vivo nephrotoxicity. The optimum formulation was determined to be composed of 50 mg/mL lecithin, 18 mg/mL VRC, and 75 mg/mL CO, with a minimum particle size of 102.96 nm, an entrapment efficiency of 71.70%, an inhibition zone of 21.76 mm, and a serum creatinine level of 0.119 mmol/L. The optimized loaded in situ gel released 82.5% VRC after 12 hours and resulted in a 5.4-fold increase in drug permeation. The in vivo results obtained using rabbits resulted in a nonsignificant differentiation among the renal function parameters compared with the negative control group. In conclusion, nasal in situ gel loaded with VRC-CO-NT is considered an efficient novel carrier with enhanced antifungal properties with no signs of nephrotoxicity.

Three types of diatomite-based adsorbents-diatomaceous earth (DE), purified diatomite (PD), and diatomite@MgO/CaO (D@MgO) were used for adsorption decontamination of ammonium from Lake Qarun water (28.7 mg/L). The adsorption properties of the three diatomite-based adsorbents were evaluated by both batch and fixed-bed column adsorption studies. The kinetic results demonstrated removal percentages of 97.2%, 69.5%, and 100% using DE, PD, and D@MgO, respectively, at a 1 g/L adsorbent dosage. The adsorption results using DE and D@MgO showed the best fitness with pseudo-first-order kinetic and Langmuir isotherm models, while the obtained results using PD demonstrate better fitness with the Freunlidich model. The recognised fitting results with the pseudo-first-order model and estimated adsorption energies demonstrated physical uptake of ammonium by DE (5.93 kJ/mol), PD (4.05 kJ/mol), and D@MgO (7.81 kJ/mol). The theoretical maximum ammonium uptake capacity of DE, PD, and D@MgO were 63.16 mg/g, 59.5 mg/g, and 78.3 mg/g, respectively. Using synthetic adsorbents in a fixed-bed column system for treating ammonium ions in Lake Qarun water resulted in removal percentages of 57.4%, 53.3%, and 62.6% using a DE bed, PD bed, and D@MgO bed, respectively, after treating approximately 7.2 L of Lake Qarun water using a bed thickness of 3 cm, a flow rate of 5 mL/min, pH 8, and the determined ammonium concentration in Lake Qarun water (28.7 mg/L). The curves demonstrated breakthrough times of 900 min, 900 min, and 960 min for the DE bed, PD bed, and D@MgO bed, respectively, with 1440 min as the saturation time. The columns' performances also were studied based on the Thomas model, the Adams-Bohart model, and the Yoon-Nelson model.

Cisplatin (cis-Diaminedichloroplatinum) is one of the most effective chemotherapeutic because of its anti-neoplastic properties against various types of tumor. However, it has a wide variety of side effects such as hepato, gastrointestinal, neuro, nephro, and cardiotoxicity (acute and/or chronic) that highly restricted its usage. Thus, research work was planned to detect the role of gold (AuNPs), silver nanoparticles (AgNPs) and their corepshell (Ag@AuNPs) as a carrier for blackberry extract and to enhance its benifit in treatment of cisplatin-induced cardiotoxicity. In our work, solid-state process was used in order to prepare these nanoparticles using pectin as an ecologically friendly-polymer acting as reductant for ions and at the same time as stabilizing agent for the produced nanoparticles. This nominated method for large-scale preparation of nanoparticles is simple, efficient, and convenient. The presence of individual metallic Ag, Au and both has been proven by UV-vis spectroscopy. Transmission electron microscopy (TEM) and particle size analyzer confirmed the preparation of spherical small size with a main diameter <40 nm. The data obtained from zeta potential evaluation displayed the well stabilization for the produced nanoparticles. Transmission electron microscopy (TEM), scanning electron microscopy (SEM) and particle size analyzer have verified that the spherical small size is <40 nm in diameter. Data from zeta potential assessment revealed the good stability of the produced nanoparticles. To this end, fifty sex rats were used in this study and divided into control, cisplatin (cispt), and five treated groups. After the experimental period, lipid profile was estimated and atherogenic coefficient (AC), atherogenic index (AI), and cardiac risk ratio (CRR) were calculated. Oxidant and antioxidant parameters were also estimated. Cardiovascular disease markers were estimated by ELISA. The mean levels of cholesterol, triglycerides, malondialdehyde (MDA), advanced oxidative protein products (AOPP), and cardiovascular markers were significantly increased in cispt group compared to control; whereas these parameters were attenuated in all treated groups in particular that received blackberry (bb) loaded Ag@AuNPs. Based on these results, it can be concluded that bb has antioxidant and antilipidemic effect that help in protecting against cardiovascular disease specially when loaded with Ag@AuNPs.

Environmental pollution with heavy metals (HMs) is of serious ecological and public health concern worldwide. Mining is one of the main sources of HMs and can impact the environment, species diversity, and human health. This study assessed the value of Spilopelia senegalensis as a biomonitor of environmental contamination with metal(loid)s caused by mining activities. S. senegalensis was collected from a gold mining site and a reference site, and metal(loid)s and biochemical parameters were determined. Lead, cadmium, mercury, vanadium, arsenic, copper, zinc, and iron were significantly increased in the liver, kidney, and lung of S. senegalensis from the mining site. Serum transaminases, alkaline phosphatase, creatinine, and urea were significantly elevated in S. senegalensis from the mining site. Lipid peroxidation and nitric oxide were increased, whereas glutathione and antioxidant enzymes were diminished in the liver and kidney of S. senegalensis from the mining site. In addition, multiple histological alterations were observed in the liver, kidney, and lung of S. senegalensis. In conclusion, mining activities provoke the accumulation of metal(loid)s, oxidative stress, and tissue injury in S. senegalensis. Therefore, S. senegalensis is a valuable biomonitor of environmental pollution caused by mining activities and could be utilized in epidemiological avian studies of human health.
RESUMEN
Mining can impact the environment, biodiversity, and human health through direct and indirect practices. This study investigated the effects of gold mining on Gerbillus nanus, in relation to organ dysfunction and redox imbalance. Soil samples, Lycium shawii, and G. nanus were collected from a site near a mining plant, and a control site. Soil and L. shawii samples from the mining site showed significantly higher cadmium (Cd), copper (Cu), mercury (Hg), arsenic (As), zinc (Zn), lead (Pb), and vanadium (V) levels. Hepatic, renal, and pulmonary Cd, Pb, Hg, Zn, Cu, Fe, As, and V concentrations were significantly higher in G. nanus from the mining site. Markers of liver and kidney function were elevated in serum, and several histological manifestations were observed in the liver, kidney, and lung of G. nanus from the mining site. Malondialdehyde and nitric oxide levels increased, and glutathione and antioxidant enzymes decreased in the liver and kidney of G. nanus. In conclusion, mining practices trigger tissue damage and oxidative stress in G. nanus that live close to the mining site. These findings can represent a scientific basis for evaluating the environmental and health impacts of mining on nearby communities.
RESUMEN
OBJECTIVES: Type 2 diabetes mellitus (DM-II) is highly prevalent in Saudi Arabia and only few studies have assessed it as a risk factor for hypothyroidism. This study aimed to examine the association between DM-II and hypothyroidism. SUBJECTS AND METHODS: We conducted a hospital-based case-control study. As cases, we included all adults admitted to King Abdulaziz University Hospital (KAUH) with laboratory-confirmed hypothyroidism. As controls, we drew a random sample of patients admitted to the orthopedic clinic at KAUH with laboratory-confirmed absence of hypothyroidism. We extracted data from the medical records regarding age, sex, presence of DM-II, HbA1c, comorbidities, treatment, and complications. We used multivariate logistic regression to identify factors associated with hypothyroidism. RESULTS: We included 121 cases and 121 controls. In comparison to controls, cases were older (P=0.005), had higher prevalence of DM-II (P<0.001), had higher levels of HbA1c (P=0.03), used insulin (P<0.001) and oral hypoglycemic drugs (P<0.001) more often, and suffered more often from hypertension (P<0.001), coronary artery disease (CAD) (P<0.001), stroke (P=0.04), diabetic foot (P<0.001), and nephropathy (P<0.001). According to multivariate regression, the risk of hypothyroidism was significantly increased among patients with DM-II (OR=4.14; 95% CI=20.20-7.80; P<0.001) and CAD (OR=14.15; 95% CI=1.80-111.43; P=0.01). CONCLUSION: Patients with DM-II were at increased risk of developing hypothyroidism. Adequate management and control of DM-II might reduce the risk of developing hypothyroidism. Further research using a prospective cohort study design is needed to confirm these findings. KEY MESSAGES: Patients with DM-II had an increased risk of developing hypothyroidism.
RESUMEN
We evaluated the frequency and outcomes of abdominal aortic aneurysm (AAA) in Qatar. Data were collected retrospectively between 2004 and 2008 for all adult patients who underwent abdominal computed tomographic scanning for any reason. Patients with AAA were followed up for 3 years for aneurysmal rupture and mortality. Of the 13,115 patients screened, 61 (0.5%) patients had abdominal aneurysms. Most (82%) patients with AAA were male with mean age of 67 ± 12 years. The incidence of AAA substantially increased with age. Cardiovascular risk factors were prevalent among patients with AAA. The main location of AAA was infrarenal (67%), followed by thoracoabdominal (23%). The mean AAA diameter was 5.3 ± 2.5 cm. The rate of AAA rupture was 8% with a mortality rate of 60%; 80% of these were infrarenal, and 80% of them had a diameter of ≥5.5 cm. Overall mortality was 33%. This large study addressed the impact of screening for AAA in a population with high cardiovascular burden.

BACKGROUND/AIMS: Despite the remarkable increase in the incidence of Crohn's disease among Saudis in recent years, data about Crohn's disease in Saudi Arabia are scarce. The aim of this study was to determine the clinical epidemiology and phenotypic characteristics of Crohn's disease in the central region of Saudi Arabia. PATIENTS AND METHODS: A data registry, Inflammatory Bowel Disease Information System (IBDIS), was used to register Crohn's disease patients who presented to the gastroenterology clinics in four tertiary care centers in Riyadh, Saudi Arabia between September 2009 and February 2013. Patients' characteristics, disease location, behavior, age at diagnosis according to the Montreal classification, course of the disease, and extraintestinal manifestation were recorded. RESULTS: Among 497 patients with Crohn's disease, 59% were males with a mean age at diagnosis of 25 years [95% Confidence Interval (CI): 24-26, range 5-75 years]. The mean duration from the time of complaint to the day of the diagnosis was 11 months, and the mean duration of the disease from diagnosis to the day of entry to the registry was 40 months. Seventy-seven percent of our patients were aged 17-40 years at diagnosis, 16.8% were ≤16 years of age, and 6.6% were >40 years of age. According to the Montreal classification of disease location, 48.8% of patients had ileocolonic involvement, 43.5% had limited disease to the terminal ileum or cecum, 7.7% had isolated colonic involvement, and 16% had an upper gastrointestinal involvement. Forty-two percent of our patients had a non-stricturing, non-penetrating behavior, while 32.8% had stricturing disease and 25.4% had penetrating disease. CONCLUSION: Crohn's disease is frequently encountered in Saudi Arabia.

AIM: To determine the clinical, epidemiological and phenotypic characteristics of ulcerative colitis (UC) in Saudi Arabia by studying the largest cohort of Arab UC patients. METHODS: Data from UC patients attending gastroenterology clinics in four tertiary care centers in three cities between September 2009 and September 2013 were entered into a validated web-based registry, inflammatory bowel disease information system (IBDIS). The IBDIS database covers numerous aspects of inflammatory bowel disease. Patient characteristics, disease phenotype and behavior, age at diagnosis, course of the disease, and extraintestinal manifestations were recorded. RESULTS: Among 394 UC patients, males comprised 51.0% and females 49.0%. According to the Montréal classification of age, the major chunk of our patients belonged to the A2 category for age of diagnosis at 17-40 years (68.4%), while 24.2% belonged to the A3 category for age of diagnosis at > 40 years. According to the same classification, a majority of patients had extensive UC (42.7%), 35.3% had left-sided colitis and 29.2% had only proctitis. Moreover, 51.3% were in remission, 16.6% had mild UC, 23.4% had moderate UC and 8.6% had severe UC. Frequent relapse occurred in 17.4% patients, infrequent relapse in 77% and 4.8% had chronic disease. A majority (85.2%) of patients was steroid responsive. With regard to extraintestinal manifestations, arthritis was present in 16.4%, osteopenia in 31.4%, osteoporosis in 17.1% and cutaneous involvement in 7.0%. CONCLUSION: The majority of UC cases were young people (17-40 years), with a male preponderance. While the disease course was found to be similar to that reported in Western countries, more similarities were found with Asian countries with regards to the extent of the disease and response to steroid therapy.
