Clinicopathological correlation of patients with lupus nephritis: Data from a tertiary center in Saudi Arabia.

Systemic lupus erythematosus mainly affects young women, and approximately half of systemic lupus erythematosus patients develop lupus nephritis (LN). However, data on the types and remission rates of LN in Saudi Arabia are limited. Therefore, we aimed to highlight the LN remission rates in our population. A retrospective record review was conducted between January 2007 and December 2020 in a tertiary center in the western region of Saudi Arabia to determine the remission rates among patients with biopsy-proven LN who met the EULAR\ACR 2019 classification criteria. We identified 59 patients with biopsy-proven LN, mostly in young women. The common histopathological pattern was Class IV LN in 26 patients (44%). Three induction protocols were identified, along with systemic steroids: the high-dose cyclophosphamide protocol in 21 patients (35.6%), low-dose protocol in 4 patients (6.8%), and mycophenolate mofetil (MMF) in 41 patients (69.5%). Partial response, defined as the reduction of the 24-hour proteinuria by 25% at 3 months and 50% at 6 months, was achieved in 18 patients (33.3%) at 3 months and decreased to 13 patients (24.1%) at 6 months. Complete clinical response, defined as 24-hour urinary protein between 500 and 700 mg at 12 months, was achieved in 44 patients (81.5%). Complete remission was higher among patients with Class IV LN (64.4%). The achievement of partial clinical response at 3 months was significantly lower among patients with hypertension (P = .041). This study presented the LN remission rates in a single center in Saudi Arabia. Similar to previous studies, Class IV LN were the most common histopathological finding in this study. Complete remission at 12 months was achieved in 44 (81%) patients. Delayed remission is associated with hypertension at the time of LN diagnosis.

Prevalence of fibromyalgia syndrome in Saudi Arabia: a systematic review and meta-analysis.

BACKGROUND: The current systematic review and meta-analysis was conducted to estimate the prevalence of fibromyalgia syndrome (FMS) in Saudi Arabia. METHODS: A PRISMA systematic search appraisal and meta-analysis were conducted. A systematic literature search of English publications in PubMed, Embase, PsycINFO, Web of Science, MEDLINE, and Google Scholar, was conducted up to December 2022. Generic, methodological and statistical data was extracted from the eligible studies. Meta-analysis was done using Comprehensive Meta-Analysis Software. The effect size estimates were calculated using the Fail-Safe N test. The funnel plot, Begg's and Mazumdar's rank correlation tests were employed to find any potential bias. The strength of the association between two variables is assessed using Kendall's tau. A fixed-effects model for the meta-analysis. RESULTS: The literature search yielded a total of 2479 studies. Eight papers were included in the final analysis with sample size ranging 40 to 1686. All studies were cross-sectional except two, which were retrospective. The total number of the participants recruited in the included articles was 4967 (1794 males and 3173 females); with age ranged between 20 and 79 years. There was high heterogeneity among studies articles (Q = 270.187; p-value 0.001); the tau value was 0.179. The pooled event rates and the 95% confidence intervals (CIs) for the prevalence of FMS in Saudi Arabia in a fixed-effects model was 13.4% (95% CI: 0.124-0.144). CONCLUSION: Our results clearly demonstrate that FMS is highly prevalent (13.4%) in Saudi Arabia. It also more common among women. The high prevalence of FMS in Saudi Arabia should be seriously considered and planners should take steps to reduce it.

Neuropsychiatric Systemic Lupus Erythematosus and Posterior Reversible Encephalopathy Syndrome in a Young Woman: A Case Report.

INTRODUCTION: Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease with variable clinical presentation, including neuropsychiatric manifestations. It has a different diagnostic approach and several different therapeutic options. CASE REPORT: We describe a case of a young woman who first presented with arthritis, serositis, and pancreatitis, and was treated with mycophenolate mofetil initially. The patient presented with neurological symptoms suggestive of neuropsychiatric manifestations three weeks later, confirmed by Brain Magnetic Resonance Imaging (MRI). The treatment was changed to cyclophosphamide; however, the day after the infusion, she developed status epilepticus and was admitted to the intensive care unit. Repeated brain MRI revealed Posterior Reversible Encephalopathy Syndrome (PRES). Cyclophosphamide was discontinued and rituximab was initiated. The patient's neurological manifestations improved, and she was discharged after 25 days of use. CONCLUSION: Immunosuppressive agents, such as cyclophosphamide have been described as a potential risk factor for PRES; however, it is not clear from the available literature whether cyclophosphamide therapy is just a marker of more severe SLE or a true risk factor for PRES.

Prevalence of Raynaud's Phenomenon in Saudi Arabia.

Purpose: Raynaud's phenomenon (RP) is defined as frequent ischaemic attacks in the fingers and toes due to vascular vasospasm. Studies have been conducted in many countries worldwide to determine the prevalence of RP. The aim of the current study was to assess the prevalence of RP in the Saudi Arabian population. Patients and Methods: An online survey based on international consensus criteria used to diagnose RP was conducted to collect data from individuals from the Saudi population. Participants were considered positive if they had triphasic or biphasic colours of the extremities with cold-related sensitivity. Awareness of RP was also assessed. Results: A total of 1025 responses were collected and included in the final analysis. The prevalence of RP was 4.29%, including 22% men and 77% women. The most common age group among women was 26-40 years (36.3%). Familiarity with RP was low, with 56.82% of participants lacking adequate awareness regarding RP. Only 32% of patients with RP reported attending doctor visits regarding symptoms of the disease. Conclusion: The RP prevalence in Saudi Arabia is comparable to that reported in the international literature. Public awareness activities should be conducted to increase knowledge about RP. Trial Registration: Not applicable.

Implications of SARS-CoV-2 infection on the clinical, hematological, and inflammatory parameters in COVID-19 patients: A retrospective cross-sectional study.

BACKGROUND: The current coronavirus pandemic (COVID-19) was caused by severe acute respiratory syndrome virus 2 (SARS-CoV-2). COVID-19 is characterized by atypical pneumonia, mild colds, and more severe illnesses, such as severe acute respiratory distress, thrombosis, organ failure, and various secondary bacterial and fungal infections. Notably, the severity of COVID-19 in different age groups is not well known, and the validity of clinical laboratory data remains unclear. METHODS: In this retrospective cross-sectional study, we examined differential regulation of clinical, hematologic, and inflammatory biomarkers in COVID-19 patients. We divided 104 COVID-19 patients into five different groups according to age (0-17, 18-45, 46-65, 66-79, and >80 years). Baseline data (sex, comorbidities, intensive care admission, and medications), hematologic markers, liver, and renal function tests, coagulation, and inflammatory markers were examined in these groups. Receiver operator characteristic (ROC) analysis was used to determine the optimal threshold for predicting COVID-19 biological markers. RESULTS: We found that the highest percentage (45%) of COVID-19 patients was in the age group of 46-65 years. The hematologic parameters (WBC, HB, and PLT) were normal between the patient groups. The area under the curve in ROC analysis showed significant differences in the levels of creatine, GGT, BUN, CRP, D-dimer, ferritin, AST, and procalcitonin between the patients of age groups 46-65 and 66-79 years. Renal biomarkers were significantly high in most patients, regardless of age. In contrast, the liver biomarkers, did not differ significantly between patient groups. CONCLUSION: The main finding of our study is that laboratory parameters such as GGT, creatinine, BUN, CRP, procalcitonin, ferritin and D-dimer were differentially regulated in COVID -19 patients of different age groups. Importantly, these laboratory parameters may help as clinical predictors to assess the severity of the disease in the population. We conclude here that age is an important factor influencing COVID-19 severity.

Prevalence and Severity of Temporomandibular Disorders in Rheumatoid Arthritis Patients.

Introduction The temporomandibular joint (TMJ) is an important joint that plays major functions, including dental occlusion, mastication, and facial expressions. Different diseases can affect the TMJ, including chronic inflammatory arthritis. Rheumatoid arthritis (RA) is the most common inflammatory arthritis worldwide associated with TMJ dysfunction. In this study, we assess the prevalence of TMJ among RA patients based on the Fonseca Anamnestic Index. Methods Eighty-one patients with rheumatoid arthritis were interviewed by a trained physician to fulfill the Fonseca Anamnestic Index questionnaire. All participants underwent a medical file review to collect their sociodemographic data, RA duration, co-existing comorbidities, and different lab results. Result According to the Fonseca score, 29.6% had no temporomandibular disorder (TMD) among RA patients, while 39.5% had mild TMD. Only 6% had severe TMD. The female sex and increased body weight were associated with TMJ disease.  Conclusion The majority of rheumatoid arthritis patients (70%) suffer from some degree of temporomandibular joint disorder.

Association Between Hypocomplementemia (C3 and C4) and MRI Findings in Different Neuropsychiatric Lupus Syndromes in a Tertiary Hospital.

Objective The aim of this study was to describe the magnetic resonance imaging (MRI) findings and correlate them with the complements level. Methodology This is a retrospective chart review study involving 187 lupus patients attending the rheumatology clinic during the period between 2010 and 2020. Out of the 187 patients, only 49 patients were diagnosed to have neuropsychiatric lupus manifestation and underwent MRI study. Results We included 49 neuropsychiatric systemic lupus erythematosus patients with a mean age of 35.33 years; most of them were Saudi (51%), with disease duration between -six and nine years (40.8%). In regard to MRI brain findings, 51% had abnormal findings, most commonly white matter changes in 42.9% followed by contrast enhancement in 36.7% and mild volume loss in 16.3%. Regarding the complement level, 21 (42.9%) patients had a low C3 level and 35 (71.4%) had a low C4 level. Lastly, following the main objective, C3 and C4 do not have a statistically significant relationship with white matter lesion given the sample of this data (p = 0.589 and p = 0.657, respectively). Conclusion MRI provides a significant clinical information to evaluate neuropsychiatric lupus manifestations. These clinical data can be correlated with immunological findings, which can help in the early diagnosis and management of this disease.

The Prevalence of Fibromyalgia Among Medical Students at King Abdulaziz University: A Cross-Sectional Study.

Background and objective Fibromyalgia (FM) is a chronic, multifactorial pain condition. The latest literature suggests that genetic and environmental factors including continuous stress contribute significantly to FM's pathophysiology. In this study, we aimed to investigate the prevalence of FM among medical students as they are considered a population significantly at risk of developing the condition. Methods This cross-sectional study was conducted at King Abdulaziz University. Medical students included in the study were recruited through a random stratified sampling method. A self-administered questionnaire was distributed to the participants; it included questions related to widespread pain index (WPI) and symptom severity scale (SSS) to assess the symptoms and diagnosis of FM, which were established based on the current diagnostic criteria. All first-year students were excluded from this research. Results A total of 450 participants were recruited for the study. Among them, 291 (64.7%) were females and 159 (35.3%) were males. Their ages ranged from 18 to 26 years, and the mean age was 21.52 years (SD: ±1.52). They came from different academic levels: 97 (21.6%) were in the second year, 79 (17.6%) were in the third year, 70 (15.6%) were in the fourth year, 99 (22%) were in the fifth year, and 105 (23.3%) were in the sixth year. The overall prevalence of FM was found to be 43 (9.6%). It was established based on the number of students who fulfilled the diagnostic criteria or were previously diagnosed with FM by a professional physician. Conclusion FM is highly prevalent among medical students. Our findings demonstrate the likelihood of the influence of medical school on causing the condition, as it has a stressful education system with high academic expectations. We recommend that this issue be seriously addressed since FM leads to a significant burden on the students and can negatively affect their future medical practice.

Acute liver failure as the first feature of systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease. Although gastrointestinal (GI) involvement is reported in the literature, GI manifestations of lupus are not common in the early disease course. GI symptoms can be related to several factors other than lupus; however, systemic lupus per se can be the responsible factor. Although the typical presentation is a gradual onset of progressive symptoms, acute abdominal pain is frequently reported and is the most serious presentation. It can reflect gastroenteritis, cholecystitis, hepatitis, pancreatitis, peritonitis, and abdominal vasculitis. When SLE diagnostic criteria for GI manifestations are lacking, the decision to implicate lupus as the cause of these manifestations is difficult, especially in the primary presentation. Early diagnosis and the initiation of immunosuppressive agents are associated with a better outcome. In this case, we introduce a patient who presented with acute abdominal pain secondary to acute liver failure as the first manifestation of lupus.

Clinicodemographic Profiles of Rheumatoid Arthritis Patients from a Single Center in Saudi Arabia.

PURPOSE: Rheumatoid arthritis (RA), if left untreated, can lead to joint damage and deformity, disability, and even death. Hence, early diagnosis and management are essential to improve clinical and functional outcomes. This study aimed to identify the most common variables and risk factors related to RA activity among patients living in the Kingdom of Saudi Arabia (KSA). PATIENTS AND METHODS: This study was conducted between January 2018 and March 2019 on consecutive patients diagnosed with RA at a tertiary care hospital in KSA. Adult patients (≥18 years old) diagnosed with RA based on the American College of Rheumatology 2010 criteria were recruited. The Disease Activity Score-28 for Rheumatoid Arthritis with CRP (DAS28-CRP) and health assessment questionnaire disability index (HAQ-DI) were calculated for 75 patients attending the rheumatology clinic during the study period to evaluate the rate of remission and functional capacity, and to compare findings with other local studies after assessing the relationship of these factors with medication use and existing comorbidities. RESULTS: The majority of the 75 patients were female (n=64), with a mean age of 49.7 years and average disease duration of 130 days. The median HAQ-DI was less than 0.5 (range 0-1.95). The DAS28-CRP scores revealed moderate disease activity in 45.3% and low disease or remission in 38.6% of the patients. Many patients (45.3%) were treated with methotrexate, and the most commonly used biological treatment was adalimumab in 14.6%. Comorbidities included hypertension (26.7%) and diabetes mellitus (18.7%). There was a strong association between cardiovascular diseases and a high DAS28-CRP score (p < 0.001). CONCLUSION: A higher RA activity rate was observed. This may be related to difficultly accessing rheumatology clinics in our facility and financial difficulties accessing biological treatments.

Anti-Neutrophilic Cytoplasmic Antibody (ANCA) Vasculitis Presented as Pulmonary Hemorrhage in a Positive COVID-19 Patient: A Case Report.

Granulomatosis with polyangiitis is a small vessel vasculitis with a wide spectrum of presentation, ranging from limited disease to life-threatening situation such as alveolar hemorrhage. Immunosuppression is the corner stone of the treatment and if left untreated, the death toll increases dramatically. We presented a case of granulomatosis with polyangiitis, presented with alveolar hemorrhage associated with COVID-19 infection. The patient admitted to the intensive care unit, received pulse steroids, plasmapheresis and intravenous immunoglobulin. She was not given further immunosuppression because of the coexisting COVID-19. Up to our knowledge, this is the first reported case of alveolar hemorrhage secondary to granulomatosis with polyangiitis coexisting with COVID-19 infection.

Acute Esophageal Necrosis Associated With Methicillin-Resistant Staphylococcus Aureus Septicemia: A Case Report.

Acute esophageal necrosis (AEN) is a multifactorial disease with a predilection for elderly male patients with multiple medical problems, including mainly hypoperfusion and malnutrition. The diagnosis is confirmed by biopsy, and AEN is managed conservatively by controlling the underlying illness. We report a case of a 65-year-old man with malnutrition, heart failure secondary to ischemic heart disease, infection with methicillin-resistant Staphylococcus aureus septicemia, and positive herpes simplex serology, who developed upper gastrointestinal (GI) bleeding. Endoscopy confirmed AEN, and he was managed conservatively with antacids, hydration, and antibiotics.

Prevalence of obstructive sleep apnea in patients with rheumatoid arthritis.

STUDY OBJECTIVES: Although previous studies suggested an increased prevalence of obstructive sleep apnea (OSA) among patients with rheumatoid arthritis (RA), no existing large prospective study has addressed this association using objective measures. This study aims to assess the prevalence of OSA using polysomnography (PSG) in patients with RA and its relationship with RA activity. METHODS: Patients with RA who presented at the rheumatology clinic at a university hospital from 2017 to 2018 were eligible. In the first stage, data from the Disease Activity Score 28, Berlin questionnaire, and Epworth Sleepiness Scale were obtained, along with personal data and a comprehensive medical history. The second stage involved a case-control study confirming OSA with PSG. OSA was defined as an apnea-hypopnea index (AHI) ≥ 5 events/h, whereas patients with an AHI ≥ 15 events/h were categorized as having moderate-severe OSA. RESULTS: In total, 199 patients with RA were recruited, 110 patients (55%) underwent PSG, and 5 were excluded. The mean age was 48.93 ± 12.7 years, and the mean body mass index was 31.70 ± 9.74 kg/m²; 94% were female. In total, 67 participants (33.2%) were at high risk for OSA (36 [55.4%] underwent PSG), whereas 132 (66.8%) were at low risk (69 [51.5%] underwent PSG). The estimated prevalence of OSA (AHI ≥ 5 events/h) in the whole population was 58.1%, whereas the prevalence of moderate-to-severe OSA (AHI ≥ 15) was 22.9%. CONCLUSIONS: This prospective PSG-based study demonstrated that OSA is more common in patients with RA than in the general population, but there appears to be no relationship with disease activity.

Post-Streptococcal Reactive Arthritis.

INTRODUCTION: Post-Streptococcal Reactive Arthritis (PSRA) is defined as inflammatory arthritis of ≥1 joint associated with a recent group A streptococcal infection in a patient who does not fulfill the Jones criteria for the diagnosis of Acute Rheumatic Fever (ARF). METHODS: In this narrative review, we conducted a systematic search on MEDLINE, EMBASE, Cochrane Library and Google Scholar using the words poststreptococcal reactive arthritis. The search covered the time period between 1982 and 2016. The purpose of this review is to summarize the current state of knowledge of PSRA with respect to the definition, epidemiology, clinical presentation and treatment. We also summarize the key differences between PSRA, reactive arthritis (ReA) and ARF. RESULTS: PSRA has a bimodal age distribution at ages 8-14 and 21-37 years with an almost equal male to female ratio. Clinically, it causes acute asymmetrical non-migratory polyarthritis, however, tenosynovitis and small joint arthritis may occur. This disease entity can be associated with extraarticular manifestations, including erythema nodosum, uveitis and glomerulonephritis. The frequency of HLA-B27 in PSRA does not differ from that of the normal population, which suggests that it is a separate entity from ReA. Involvement of the axial skeleton, including sacroiliitis, is uncommon in PSRA. PSRA tends to occur within 10 days of a group A streptococcal infection, as opposed to the 2 to 3 weeks delay for ARF. PSRA can be associated with prolonged or recurrent arthritis, in contrast to ARF, in which arthritis usually lasts a few days to 3 weeks. Treatment usually involves NSAIDs or corticosteroids. CONCLUSION: We summarize clinical features that help differentiate PSRA from ARF and ReA. First-line treatment options include NSAIDs and corticosteroids. Most cases resolve spontaneously within a few weeks, but some cases are recurrent or prolonged. There are no published randomized controlled trials of PSRA.

Frequency of sleep disorders in patients with rheumatoid arthritis.

Purpose: To determine the prevalence of common sleep problems among patients with rheumatoid arthritis (RA) and their relationship with the disease activity and quality of life. Patients and methods: The study sample consisted of 101 patients who attended a rheumatology clinic at a university hospital between October 2015 and May 2016. All subjects were clinically examined and interviewed by physicians using a questionnaire. The collected information included sociodemographic characteristics, the patients' medical histories, the Disease Activity Score (DAS28), the Berlin questionnaire to assess the risk of obstructive sleep apnea (OSA), the Epworth Sleepiness Scale to assess excessive daytime sleepiness (EDS), the Athens Insomnia Scale to assess insomnia, the International RLS Study Group score to diagnose restless legs syndrome (RLS), and the Health Assessment Questionnaire (HAQ) to assess the quality of life. Results: The mean age of the participants was 48.7±14.6 years, and 95% of the participants were females. Approximately 60% of the participants were in the remission/low category of disease activity, and the average DAS28 score was 3.3±0.8 years. The prevalence rates of insomnia, EDS, sleep disturbance, risk of OSA, and RLS were 63%, 20%, 20%, 37%, and 63%, respectively. Furthermore, the distribution of sleep disorders was not affected by the disease activity. The association between the HAQ and sleep disorders among the RA patients was not significant. Conclusion: Sleep disorders are common among RA patients and may require further attention by treating clinicians; nevertheless, these disorders are not associated with disease activity and do not affect the quality of life.

Internal medicine residents' perspectives and practice about do not resuscitate orders: survey analysis in the western region of Saudi Arabia.

BACKGROUND: The purpose of this study was to analyze the perceptions and practices of internal medicine residents in the western region of Saudi Arabia regarding the implementation of do not resuscitate (DNR) orders to improve future training practices among physicians. METHODS: Medical residents involved in training programs in the western region of Saudi Arabia, including Jeddah, Makah, Medinah, and Taif, were invited to participate in a cross-sectional, anonymous, online survey regarding DNR orders. The 16-question survey was distributed to residents in all training programs in the region using surveymonkey.com, and the results were collected and tabulated. RESULTS: Of 364 residents, 157 completed the questionnaire, resulting in a 43% response rate. The study showed that most (66%) internal medicine residents in the western region of Saudi Arabia participate in DNR discussions with patients and family or surrogate decision-makers. In addition, 43% were observed by faculty members, and half of them (51.9%) reported feeling comfortable during these discussions. Furthermore, most residents believed that additional educational programs would enhance their competence in addressing issues related to DNR discussions. CONCLUSION: This study highlights the need for a structured curriculum to teach skills relating to end-of-life issues such as DNR orders to residents in the Saudi Arabian medical system. The majority of residents surveyed believe they would benefit from additional training in DNR discussions. Therefore, an evidence-based curriculum providing instruction for improving discussions regarding DNR orders would improve physician confidence and effectiveness in caring for critically ill patients.
