RESUMEN
INTRODUCTION: Graves' disease (GD) is an autoimmune disorder characterized by hyperthyroidism due to increased thyroid-stimulating hormone receptor antibodies (TRAb).The treatment of GD often consists of radioactive iodine therapy, anti-thyroid drugs (ATD), or thyroidectomy. Since few studies have collected data on remission rates after treatment with ATD in Saudi Arabia, our study aimed to assess the efficacy and the clinical predictors of GD long-term remission with ATD use. METHOD: We conducted a retrospective chart review study of 189 patients with GD treated with ATD between July 2015 and December 2022 at the endocrine clinics in King Abdulaziz Medical City in Riyadh. All GD patients, adults, and adolescents aged 14 years and older who were treated with ATD during the study period and had at least 18 months of follow-up were included in the study. Patients with insufficient follow-up and those who underwent radioactive iodine (RAI) therapy or thyroidectomy as first-line therapy for GD were excluded from the study. RESULTS: The study sample consisted of 189 patients, 72% of whom were female. The patients' median age was 38years (33, 49). A total of 103 patients (54.5%) achieved remission. The median follow-up period for the patients was 22.0 months (9, 36). Patients who achieved remission had lower mean free T4 levels (25.8pmol/l ± 8.93 versus 28.8pmol/l ± 10.82) (P value = 0.038) and lower median TRAb titer (5.1IU/l (2.9, 10.7)) versus (10.5IU/l (4.2, 22.5)) (P value = 0.001) than patients who did not achieve remission. Thirty-five out of 103 patients who achieved remission (34%) relapsed after ATD discontinuation. The patients who relapsed showed higher median thyroid uptake on 99mTc-pertechnetate scan than patients who did not relapse: 10.3% (5.19, 16.81) versus 6.0% (3.09, 12.38), with a P value of 0.03. They also received ATD for a longer period, 40.0 months (29.00, 58.00) versus 25.0 months (19.00, 32.50), with a P value of < 0.0001. CONCLUSION: The remission of GD was achieved in approximately half of the patients treated with ATD; however, approximately one-third of them relapsed. Lower Free T4 and TRAb levels at diagnosis were associated with remission. Longer ATD use and higher thyroid uptake upon diagnosis were associated with relapse after ATD discontinuation. Future studies are necessary to ascertain the predictors of ATD success in patients with GD.

BACKGROUND: Impulse control disorders (ICDs) have been described as underrecognized side effects of dopamine agonists (DAs) in neurological disorders but are not sufficiently understood in endocrine conditions. OBJECTIVE: To identify the prevalence of DAs induced ICDs and determine potential risk factors related to these disorders in patients with prolactinoma and non-function pituitary adenomas (NFPAs). METHODS: This is a cross-sectional multicenter study involving 200 patients with prolactinoma and NFPAs, who received follow-ups in tertiary referral centers. DA-induced ICDs were assessed using ICD questionnaires modified from prior studies. RESULT: At least one ICD was reported by 52% of participants, among whom 28.5% mentioned compulsive shopping, 24.5% punding, and 24.5% hypersexuality. Furthermore, 33% of the patients reported the presence of one type of ICD behavior, while 12% specified two and 7% had three types of such behavior. The multivariable logistic regression showed that the significant risk factors of ICD were younger age (adjusted odds ratio [AOR]: 0.92, 95% confidence interval [CI]: 0.88-0.97, p 0.001), being single (AOR: 0.15, 95%CI: 0.03-0.84, p 0.03), and a positive history of psychiatric illness (AOR: 7.67, 95% CI: 1.37-42.97, p 0.021). CONCLUSION: ICDs with a broad range of psychiatric symptoms are common in individuals with DA-treated prolactinoma and NFPAs. Endocrinologists should be aware of this potential side effect, particularly in patients with a personal history of psychiatric disorder.

INTRODUCTION: Hypogonadism is the most common form of hypopituitarism in men with macroprolactinoma. However, evidence on factors related to hypogonadism recovery is limited. OBJECTIVES: We estimated the proportion of hypogonadism in men with macroprolactinoma exclusively treated with dopamine agonists, and we assessed the factors predicting hypogonadism recovery. PATIENTS AND METHODS: This was a multicenter retrospective study of men with macroprolactinoma identified using ICD 9 and 10 codes and treated between 2009 and 2019 in five centers in the United Arab Emirates and Saudi Arabia. We evaluated hypogonadism, defined as low total testosterone (TT) level with normal or low gonadotropins on presentation and during the last clinic visit. RESULTS: A total of 79 patients (median age 32 years) were included in the study. The most common symptoms at presentation were headache (73.7%), erectile dysfunction (55.4%), and low libido (54.3%). The median tumor size was 2.9 cm (1.0-9.7) at diagnosis. Sixty-three patients (79.7%) had hypogonadism at baseline. Growth hormone deficiency (GHD) and hypothyroidism were present in 34.4% and 32.9% of patients, respectively. The median serum prolactin (PRL) level was 20,175 (min-max 2254 - 500,000) mIU/l with a median serum TT of 4.5 (min-max 0.4-28.2) nmol/l. Most patients were treated with cabergoline (n = 77, 97.5%) with a median of 6 (min-max 0.6-22) years. At follow-up, 65% of patients recovered their pituitary-testicular axis. Patients with recovered hypogonadism had smaller median tumor size (2.4 [1-5.4] vs. 4.3 [1.6-9.7], p = 0.003), lower PRL level (18, 277 [2254 - 274, 250] vs. 63,703 [ 3,365-500,000], p = 0.008 ), higher TT level (4.6 [0.6-9.2] vs. 2.3 [0.5-7.3], p = 0.008), lower PRL normalization time on medical therapy (8 months (0.7-72) vs. 24 (3-120), p = 0.009) as well as lower frequency of GHD (17.1% vs. 60%, p = 0.006) and secondary hypothyroidism (17.9% vs. 57.1%, p = 0.003) compared with those with persistent hypogonadism respectively. Age at diagnosis, presenting symptoms and duration of medical therapy did not predict hypogonadism recovery. CONCLUSIONS: About two-thirds of men with macroprolactinoma recover from hypogonadism, mostly with 24 months of therapy. Smaller adenoma size, lower prolactin level, earlier prolactin normalization, and higher testosterone patients were related to testosterone normalization.

CONTEXT: Time pressure has been implicated in the suboptimal diagnostic performance of doctors and in increases in diagnostic errors. However, the reasons underlying these effects are not clear. The aim of this study was to investigate the influence of time pressure on physicians' diagnostic accuracy and to explore the mediating effects of perceived stress (emotional pathway) and number of plausible diagnostic hypotheses (cognitive pathway) on the proposed relationship. METHODS: We conducted a randomised controlled experiment. A total of 75 senior internal medicine residents completed eight written clinical cases under conditions with (n = 40) or without (n = 35) time pressure. They were then asked to: (i) rate the overall stress experienced, and (ii) write down any alternative hypotheses they had thought of when diagnosing the cases. In a post hoc analysis, a mediation path analysis was performed to test the causal relationships between time pressure, perceived stress and number of alternative diagnoses. RESULTS: Participants who were under time pressure spent less time diagnosing the cases (85.54 seconds versus 181.81 seconds; p< 0.001) and had a lower mean diagnostic accuracy score (0.44 versus 0.53; p = 0.01). In addition, they reported more stress (5.80 versus 4.69; p = 0.01) and generated fewer plausible tentative hypotheses (0.37 versus 0.51; p = 0.01). Two path coefficients were found to be statistically significant; the first path coefficient referred to the relationship between time pressure and perceived stress (standardised ß = 0.25, p = 0.029), and the second negative path coefficient referred to the relationship between time pressure and number of plausible alternative hypotheses (standardised ß = -0.32, p< 0.01). CONCLUSIONS: Time pressure adversely influences physicians' diagnostic accuracy by increasing their stress response and reducing the number of plausible hypotheses as mediators.

Alemtuzumab, an anti-CD52 monoclonal antibody, was recently approved for treatment of MS in Canada, having shown to significantly reduce relapses and disability in patients, particularly those who relapsed despite first line treatment. Offsetting its benefit however, is the development of novel secondary autoimmune disease, particularly affecting the thyroid gland in up to 36% of patients. The incidence of Alemtuzumab induced thyroid dysfunction (AITD) will likely rise as alemtuzumab becomes more widely used for treating MS. We review the clinical and investigational cues that help delineate the aetiology and management of thyrotoxicosis and hypothyroidism in ATID. AITD can be easily managed and we present a simple approach for its evaluation and management by neurologists that should be implemented prior to considering a referral to an internist or endocrinologist for further opinion or treatment.

INTRODUCTION: Achieving target low-density lipoprotein-cholesterol (LDL-C) levels remains challenging when treating homozygous familial hypercholesterolemia (HoFH). Proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) are prescribed in addition to statins and ezetimibe, but patients' response varies and depends on residual low-density lipoprotein receptor (LDLR) function. METHODS: A multicenter, retrospective observational analysis evaluated LDL-C target achievement in response to PCSK9i treatment in 28 patients with HoFH from the Middle East/North Africa region. Effect of genotype was investigated. Demographic and clinical information was retrospectively obtained from medical records. Patient response to PCSK9i treatment was assessed by calculating percentage changes in lipid levels from pre-PCSK9i treatment baseline to most recent follow-up visit where patients were recorded as receiving PCSK9i on top of standard of care lipid-lowering therapies (LLTs; i.e., statins/ezetimibe) and assessing European Atherosclerosis Society (EAS) target achievement up to January 31, 2022. Lowest LDL-C level while receiving PCSK9i was identified. RESULTS: The cohort (n = 28) had a mean age (standard deviation; SD) of 22.8 (9.8) years (n = 28) and was 51% female (n = 27). Baseline LDL-C data were available in 24/28 (85.7%) patients (mean [SD] 14.0 [3.0] mmol/L). Median (interquartile range) duration of PCSK9i treatment was 12.0 months (4.0-19.1) months and mean (SD) % change in LDL-C after PCSK9i treatment was - 8.6% (12.1). LDL-C reduction from baseline was below 15% in 17/24 patients (70.8%). In the full cohort, mean (SD) minimum LDL-C during PCSK9i treatment was 11.9 (2.8; n = 28) mmol/L. No patient achieved EAS target LDL-C while receiving PCSK9i; genotype analysis suggested LDLR-null/null patients were most refractory to PCSK9i. CONCLUSION: Response to PCSK9i was minimal in this cohort of patients with HoFH. No patients achieved EAS LDL-C targets, and most failed to reach the EAS-recommended 15% LDL-C reduction for PCSK9i therapy continuation. These results suggest additional LLTs are necessary to achieve LDL-C targets in HoFH.

Liraglutide, a glucagon-like peptide 1 receptor agonist, effectively treats type 2 diabetes(T2D) by lowering glucose levels, suppressing glucagon release, and promoting insulin secretion. Liraglutide has been shown to reduce body weight and glycated hemoglobin (HbA1c) levels and improve cardiovascular outcomes. However, evidence regarding the association between liraglutide and diabetic retinopathy in the Middle East is insufficient. Therefore, this study aimed to investigate the characteristics and risk factors of diabetic retinopathy in patients with T2D treated with liraglutide in Saudi Arabia. This retrospective cohort study was conducted on patients (≥14 years) with T2D treated with liraglutide between 2015 and 2021, who had a documented retinopathy assessment at baseline before liraglutide initiation and during follow-up, at King Abdulaziz Medical City (KAMC), Riyadh. Data collection included demographic information, retinopathy status, body mass index (BMI), and HbA1c level at baseline and follow-up after liraglutide use. The study included 181 patients with a mean age of 58.2 (9.8) years. Of these, 72.9% were females. At baseline, the median weight (interquartile range) was 88 (77-100) kg, diabetes duration was 19 (13-23.5) years, and HbA1c level was 9% (8-10%). Total of 69.6% were on insulin, 22.7% were on oral hypoglycemic agents, and 7.7% were on no other medications in addition to liraglutide. After a median of 2 years follow-up, both HbA1c level and weight decreased significantly (Pâ <â .001). Seventy-one of the 87 patients (81.6%) without retinopathy at baseline continued to show no retinopathy. Among patients with retinopathy at baseline, 25.5% showed improvement and 44.7% showed no change. In the multivariate binary mixed effect analysis, factors significantly associated with retinopathy were: use of insulin (odds ratio [OR]:2.68; 95% confidence interval [CI]: 1.18-6.09, Pâ =â .019), older age (OR:1.03; 95% CI: 1.00-1.06; Pâ =â .022), higher HbA1c level (OR:1.17; 95% CI: 1.02-1.34; Pâ =â .024), Hypertension (OR:2.56; 95% CI: 1.13-5.76; P=<.0001) and longer diabetes duration (OR:1.04; 95% CI: 1.00-1.08; Pâ =â .024). In conclusion, liraglutide use caused significant reductions in the HbA1c level and weight of patients with T2D. Most patients showed no change in retinopathy status after liraglutide use.

Objective: Type 2 diabetes mellitus (T2DM) and post-transplant diabetes mellitus (PTDM) are common in renal transplant recipients. Semaglutide has demonstrated efficacy and safety in patients with T2DM. To date, only a limited number of studies have investigated its use in renal transplant patients. This study assessed the safety and efficacy of semaglutide in post-renal transplant patients. Methods: A retrospective study was conducted at king Abdulaziz Medical City-Riyadh, Saudi Arabia. The subjects of the study were adults and adolescents (>14 years) who had undergone a kidney transplant and had pre-existing T2DM or PTDM. The study subjects were given semaglutide during the study period, from January 2018 to July 2022. The data were collected over a period of 18 months. Results: A total of 39 patients were included, 29 (74 %) of whom were male. A significant decrease in hemoglobin A1c (HbA1c) was observed during the follow-up period when compared to baseline (8.4 %±1.3 % at baseline vs. 7.4 %±1.0 % at 13-18 months (p < 0.001). A significant reduction in weight was also noted at follow-up as compared to baseline (99.5 kg ± 17.7 vs 90.7 kg ± 16.8 at 13-18 months (p < 0.001). No significant changes were found in renal graft function markers. Conclusion: Semaglutide was found to significantly reduce HbA1c levels and weight in post renal transplant patients with diabetes. No significant changes in markers of renal graft function were observed.
RESUMEN
Aim: To assess the efficacy and safety of Dipeptidyl Peptidase IV (DPP-4) inhibitors in patients with Type-2 Diabetes Mellitus (T2DM) and chronic kidney disease (CKD) using level 1 evidence. Methods: The Cochrane and PubMed databases were searched from inception until January 1, 2022. RCTs that studied the efficacy and safety of DPP-4 inhibitors in diabetic patients with CKD were included. The primary efficacy outcome was assessed as the mean difference between HbA1c at the beginning and the end of each study for each arm, and the primary safety outcome was assessed as the incidence of adverse events and severe adverse events in each study. Results: Twenty-one studies satisfied the pre-defined eligibility criteria. In assessing the efficacy of DPP-4 inhibitors in the treatment of T2DM and CKD, a total of 2917 patients under the DPP-4 inhibitors group and 2377 patients under the control group were included; The mean difference between the HbA1c of DPP-4 Inhibitor and the control group was -0.5295 with a 95% CI of -0.5337 to -0.5252. The included studies had high heterogeneity p < 0.00001 and I2 = 99%. In assessing the safety outcome and tolerability of DPP-4 inhibitors, a total of 8138 patients under the DPP-4 inhibitors group and 7517 patients under the control group were included; the odds ratio of adverse events between both groups was 0.9967 with a 95% CI of 0.9967 to 1.1047. The included studies had low heterogeneity p = 0.25 and I2 = 15%. The overall effect, Z = 0.06 (p = 0.95), was insignificant. Conclusion: Patients suffering from both T2DM and CKD exhibited a significantly enhanced glycemic control when treated with DPP-4 inhibitors in comparison to the control group. Furthermore, no significant difference in the incidence of adverse events was observed between the DPP-4 inhibitors and the control group.
RESUMEN
Background: Sitosterolemia is a relatively rare metabolism lipid disorder, with about 110 cases worldwide and only a few known cases from the Middle East. Sitosterolemia is characterized by excessive uptake of phytosterols and their deposition in various tissues, leading to complications. Mutations in the ABCG5 and ABCG8 genes are associated with pathological changes in sitosterolemia. Case Presentation. An adult patient from Saudi Arabia with dyslipidemia who did not respond to statin therapy. Based on genetic testing, the patient was eventually diagnosed with sitosterolemia. Ezetimibe significantly improved his cholesterol levels. Conclusion: The diagnosis of sitosterolemia is confirmed by the detection of high-phytosterol levels and pathological mutation in the ABCG5 and ABCG8 genes. Treatment of sitosterolemia is based on dietary changes and drugs to inhibit cholesterol absorption, such as ezetimibe.
RESUMEN
Pheochromocytoma (PCC) is a neuroendocrine tumor that may present with headaches, palpitations, and hypertension, and if left unresected, it can lead to serious complications and fatal cardiac mortality. Adequate preoperative management can decrease the risk of intraoperative complications. In this systematic review, we address and discuss what has been published in the literature about the optimization of pheochromocytoma preoperative care via various types of telemedicine (TM). We searched health research databases PubMed, Medical Literature Analysis and Retrieval System Online (MEDLINE), the Cochrane Library, and Google Scholar for literature on various types of TM employed for PCC preoperative management. We searched peer-reviewed literature in the English language published in the literature until November 5, 2022, using medical subject heading (MeSh) terms in PubMed like "telemedicine" and "pheochromocytoma." We used "telemedicine" or "telehealth" and "pheochromocytoma" in other databases. We considered all types of TM, including synchronous, asynchronous, and remote patient monitoring. Our search yielded five publications in PubMed, 59 results in Google Scholar, and none in the Cochrane Library. After excluding duplicates and evaluating the articles for relevance, five papers were selected for this review. Studies came from the United States and Italy. Findings from these studies suggested safe outcomes and reduced costs compared to what is traditionally followed in physical settings. Overall, this systematic review shows the convenience and safety of TM use for a broad spectrum of patients. Further studies are needed to consolidate these findings. Moreover, guidelines on patients' selection and procedures for safe and effective TM care for patients with PCC are required.
RESUMEN
BACKGROUND: Adherence Therapy is a candidate intervention to promote consistent medication taking in people with type 2 diabetes. The aim of this study was to establish the feasibility of conducting a randomized controlled trial of adherence therapy in people with type 2 diabetes who were non-adherent with medication. METHODS: The design is an open-label, single-center, randomized controlled feasibility trial. Participants were randomly allocated to receive either eight sessions of telephone-delivered adherence therapy or treatment as usual. Recruitment occurred during the COVID-19 pandemic. Outcome measures-adherence, beliefs about medication, and average blood glucose (sugar) levels (HbA1c)-were administered at baseline and after 8 weeks (TAU group) or at the completion of the treatment (AT group). Feasibility outcomes included the number of people approached to participate in the trial and the numbers that consented, completed study measures, finished treatment with adherence therapy, and dropped out of the trial. Fieldwork for this trial was conducted in the National Guard Hospital, a tertiary care provider, in the Kingdom of Saudi Arabia. RESULTS: Seventy-eight people were screened, of which 47 met eligibility criteria and were invited to take part in the trial. Thirty-four people were excluded for various reasons. The remaining thirteen who consented to participate were enrolled in the trial and were randomized (AT, n = 7) (TAU, n = 6). Five (71%) of the seven participants in the adherence therapy arm completed treatment. Baseline measures were completed by all participants. Week 8 (post-treatment) measures were completed by eight (62%) participants. Dropout may have been linked to a poor understanding of what was involved in taking part in the trial. CONCLUSIONS: It may be feasible to conduct a full RCT of adherence therapy, but careful consideration should be given to developing effective recruitment strategies, consent procedures, rigorous field testing, and clear support materials. TRIAL REGISTRATION: The trial was prospectively registered with the Australian New Zealand Clinical Trials Registry (ANZCTR), ACTRN12619000827134, on the 7th of June 2019.
RESUMEN
Objective: Curriculum development and reviews are of paramount importance for academic programs curriculum management. Medical curricula need proper construction and frequent updates to suits learning outcomes considering their integrative nature and rapid scientific advancement. Curriculum alignment and mapping are fundamental for proper integration and planning of medical curriculum. This process is beneficial in detecting gaps and redundancies, and ensuring proper instruction, integration, and transparency. However, there is a paucity in the literature of a practical guidance to such process. Hence, this manuscript provides a practical guidance that was adopted in our institutes. Methods: A detailed description of twelve step-by-step guidance to curriculum alignment and mapping was provided. The process needed for each step and the flow chart of work was detailed. Results: This guide was developed and implemented successfully. Among many benefits encountered, many gaps in the contents, learning outcomes and assessment methods were detected and rectified. Additionally, better curriculum integration has been achieved. The current mapping will make any future curriculum reviews easier. Conclusion: This guide could be utilized by newly developed and existing programs for curriculum alignment and mapping. It fills a gap in academic literature through stepwise workflow which has been tested and implemented.
RESUMEN
Objectives This study aims to describe the disease parameters of children and adolescents diagnosed with non-alcoholic fatty liver disease (NAFLD) in Saudi Arabia. It also investigates the disease's progression and compares clinical, biochemical, and radiological parameters at baseline and follow-up of patients with NAFLD. This study was done between two groups of patients: obese and those of average body weight. Methods A retrospective cohort study was conducted between 2014 and 2018 through retrieved data from medical records. It included all children aged between six to 18 years diagnosed with NAFLD. Medical history was taken from each medical record, liver function test results, cholesterol, blood pressure readings, and body weight. Data have been restored from King Abdullah Specialist Children's Hospital (KASCH)â, Security Forces Hospital (SFH), and King Khalid University Hospital (KKUH). Results A total of 116 subjects met the inclusion criteria; 65 (56%) were male, and 81 (70%) were obese. The majority of subjects (n=112) had mild NAFLD, with (71%) obese and (29%) non-obese, followed by moderate NAFLD with 50% among obese and non-obese (N=2), and non-alcoholic steatohepatitis (NASH) with 100% non-obese (N=2). Data showed that patients' proportion of obese to non-obese is 70% (N=81) to 30% (N=35), respectively. Conclusion NAFLD was found to affect obese children and adolescents more than non-obese, and male patients had a higher proportion of NAFLD than females. Also, obese patients had more advanced stages of NAFLD than non-obese patients. Finally, most subjects had been diagnosed with mild stage while a few had developed NASH.
RESUMEN
Introduction: Hypothyroidism requires lifelong thyroid hormone replacement with levothyroxine. For most hypothyroid patients fasting during Ramadan, compliance with the administration procedure is a challenge. This study aimed to determine the impact of different administration times of levothyroxine on thyroid-stimulating hormone (TSH) and free T4 (FT4) levels before and after the holy month of Ramadan. Materials and Methodology. Hypothyroid patients taking levothyroxine were randomized to 3 groups during Ramadan: group 1, 30 minutes before the iftar meal; group 2, 3-4 hours after the iftar meal, with no food taken for at least 1 hour after the meal; group 3, they were not given specific instructions for taking levothyroxine during Ramadan. Thyroid function tests were performed within 2 weeks before Ramadan and within 2 weeks after Ramadan. Pre- and post-Ramadan TSH and free T4 levels were compared. Mixed-effects analyzes were performed to identify factors associated with changes in TSH and FT4 levels. Results: Compliance was lower in patients taking levothyroxine 3-4 hours after iftar. In addition, the majority of patients who had not received a specific recommendation took levothyroxine 30 minutes before iftar. There was a statistically significant increase in TSH (P=0.006) and FT4 (P=0.044) levels after Ramadan. In multivariate analysis, the cause of hypothyroidism (Hashimoto's; postthyroidectomy; compared to postradioactive iodine) and levothyroxine dose significantly affected FT4 levels. In contrast, no variable was significantly associated with TSH level. The timing of levothyroxine intake during Ramadan did not significantly affect TSH or FT4 levels. Conclusion: TSH and FT4 significantly increased after Ramadan. However, the timing of levothyroxine intake per se had no influence on TSH or free T4 levels. Therefore, hypothyroid patients might take levothyroxine either 30 minutes or 3-4 hours after iftar with no meal for 1 hour, depending on preference.
RESUMEN
Background Hypogonadism is a condition in which the body's ability to produce sex hormones is reduced. Androgen deficiency and hypothyroidism are similar in many symptoms, and the coexistence of the two conditions is common. The aim of this study is to explore the prevalence of hypogonadism symptoms in male patients diagnosed with primary hypothyroidism. Methods This cross-sectional study was conducted at â¯King Abdulaziz Medical City â¯in Riyadh, â¯Saudi Arabia, with a sample size of 120 adult male patients with primary hypothyroidism. Data collection primarily relied on one instrument, namely, theâ¯Androgen Deficiencyâ¯in Aging Males (ADAM) questionnaire, which was translated into Arabic and validated by previous researchers. Results A total of 120 adult males with hypothyroidism completed the ADAM questionnaire. Out of the 120 patients, 67.5% had a positive screen for hypogonadism. Among patients who had hypogonadism symptoms on the questionnaire, 81% had a BMI above 25, 69% were older than 40, and 65% were smokers. Conclusion Hypogonadism symptoms are common in male patients with primary hypothyroidism. Among patients with primary hypothyroidism, increasing age and being overweight added to the likelihood of having hypogonadism symptoms.
RESUMEN
Adrenal insufficiency (AI) is a relatively rare disease. While the adrenocorticotropic hormone (ACTH) stimulation test remains as one of the commonly used diagnostic test for AI, to date there is no consensus on the cortisol cutoff value post-ACTH stimulation test. This study aimed to investigate and characterize the cortisol response after the standard ACTH stimulation test in a group of Saudi Arabian patients. A single center retrospective study was conducted on Saudi Arabian adult patients who underwent ACTH stimulation test at the endocrinology clinics of King Abdulaziz Medical City in Riyadh, Saudi Arabia between 2015 and 2018. Demographic, clinical and biochemical variables were collected and analyzed. A total of 154 medical records of patients (44 males, 110 females, mean age 44.4â ±â 17.0 years) were included in the study. All patients underwent ACTH stimulation test. Fatigue was the most common symptom of participants. Type 1 diabetes was the most frequent comorbidity. Cortisol levels were significantly lower in patients who received corticosteroid replacement therapy, and, within the context of ACTH stimulation tests, were useful in diagnosing AI in patients with vague symptoms and signs. For basal cortisol, the cutoff of ≤258.5 has a sensitivity and specificity of 69.2% and 58.6%, respectively. For 30-minute, the cutoff of ≤386 sensitivity and specificity are 61.5% and 69.0%. For 60-minute, the cutoff of ≤491.5 has a sensitivity and specificity of 61.5% and 65.5%, respectively. Higher cortisol cutoff values have better sensitivity. Patients with AI present with mostly nonspecific symptoms, with type 1 diabetes as the most common comorbidity. The cortisol level cutoffs obtained from Arab patients who underwent ACTH stimulation tests showed wide variability for its utility in AI diagnosis. Further studies to evaluate the optimal cortisol cutoff values for AI diagnosis in this population are needed.

BACKGROUND: Prolactin is a hormone of the pituitary gland whose main function is the production of milk. Hyperprolactinemia is defined as an increase in prolactin levels above 25 µg/L in women and 20 µg/L in men. Causes of hyperprolactinemia include pituitary tumors, especially prolactinomas. Hyperprolactinemia can manifest clinically with a variety of symptoms, including galactorrhea and menstrual irregularities in women and erectile dysfunction in men. There are limited data on the epidemiology of hyperprolactinemia in the Middle East region. OBJECTIVES: Description of the epidemiology and clinical features of hyperprolactinemia in a cohort from Saudi Arabia. DESIGN: Medical record review SETTING: Tertiary medical center in Riyadh PATIENTS AND METHODS: The study included adult patients with hyperprolactinemia in King Abdulaziz Medical City in Riyadh. The patients were treated in endocrinology clinics from 2015 to 2019. Patients of both sexes older than 14 years were enrolled in the study. Patients with insufficient follow-up were excluded. Data were collected on demographic characteristics, symptoms, prolactin level, cause of high prolactin level, and treatment. MAIN OUTCOME MEASURES: The frequency of different etiologies and symptoms in patients with hyperprolactinemia. SAMPLE SIZE: 295 patients RESULTS: The majority of patients with hyperprolactinemia were female 256 (86.8%). Hyperprolactinemia was diagnosed more frequently in patients in the age groups 21-30 years (42.6%) and 31-40 years (24.1%). The majority of the study population was obese or overweight: 136 (46.3%) and 74 (25.2%), respectively. Most of the cases were symptomatic (192, 65.1%). In women, the most common symptom was oligomenorrhea (35%). In men, infertility and erectile dysfunction were the most common clinical symptoms (50% and 44.7%, respectively). Idiopathic causes were the most common etiology (108, 36.6%), followed by pituitary adenomas (81, 27.5%). The majority of patients were treated (184,62.4%), with cabergoline being the most commonly used medication (173, 94.0%). CONCLUSION: The demographic and clinical presentations and causes of hyperprolactinemia in male and female Saudi patients were similar to that in studies in other populations. LIMITATIONS: Single-center retrospective chart review study. CONFLICT OF INTEREST: None.

Background: Osteoporosis is characterized by a decrease in bone mineral density, thereby increasing the risk of pathological fractures. It is a common complication of chronic kidney disease. However, there is limited local data on the prevalence of osteoporosis in end-stage renal disease. Objective: The current study evaluated the epidemiology of osteoporosis in end-stage rental disease patients at a Saudi Arabian tertiary care center. Methods: This cross-sectional retrospective study was conducted using data obtained between 1 January 2016 and 31 December 2019 at the Dialysis Center at King Abdulaziz Medical City, Riyadh, Saudi Arabia. End-stage rental disease patients who were aged ≥50 years and underwent hemodialysis for at least 1 year were included, while those with documented metabolic bone disease and absence of bone mineral density data were excluded. Results: Sixty-four end-stage rental disease patients undergoing hemodialysis met the inclusion criteria. The patients underwent bone mineral density measurement at the discretion of the treating physician. The mean patients' age was 73 ± 11.5 years and 76% were women. The overall prevalence of osteoporosis was 37.5%, and it was similarly distributed among women and men (38.8% and 33.3%, respectively). Nine of the 15 male patients (60%) and 24 of the 49 female patients (49%) had fractures. Twenty-five (39%) patients used glucocorticoids. Osteoporosis was most commonly identified in the femoral neck (26.2%), followed by proximal femur (19.4%), and lumbar spine (18.8%). A high rate of osteoporosis was significantly associated with older age and being underweight. Conclusion: A high rate of low bone mineral density was demonstrated in end-stage renal disease patients. The femoral neck was the most common osteoporosis site in this patient population, and advanced age and underweight were possible risk factors for low bone mass.
