Background There is a growing literature reporting the association between proton pump inhibitor (PPI) use and subacute cutaneous lupus erythematosus (SCLE). Aims To compare the clinical characteristics of a cohort of patients with PPI-induced SCLE, their clinical course and treatment with a control group of primary SCLE patients not exposed to PPI. Methods We conducted a matched case–control study in a tertiary referral setting at the Louise Coote Lupus Unit. There were 64 SCLE patients: 36 with PPI-induced SCLE and 28 patients with primary SCLE. Results Twenty-six patients (72%) had pre-existing SLE in the PPI-induced SCLE group. Lower limb skin lesions were significantly more prevalent in the PPI group ( p < 0.0001). The prevalence of anti-Ro and anti-Ro-52 antibodies was numerically higher in the PPI group (64% and 60%), respectively, compared with 46% and 42% in the primary SCLE group. Peripheral blood eosinophils were normal in all patients in the PPI group. Thirteen patients underwent skin biopsy in the PPI group and 12 had histology in keeping with SCLE. The median time to presentation was 8 months with a median resolution period of 6 weeks. PPIs were stopped in 34 patients, while 2 patients continued treatment for other clinical indications. Twelve patients received concurrent oral corticosteroids. Two patients had severe SCLE in the form of Toxic Epidermal Necrolysis requiring critical care admission and were managed with corticosteroids, IV immunoglobulin and/or belimumab. Conclusion Lower limb involvement is a pointer to PPI-induced SCLE which is likely a class effect with all PPI.
BackgroundSimilar to coronavirus disease 2019 , the pathogenesis of inflammatory rheumatic diseases includes cytokines dysregulation and increased expression of pro-inflammatory cytokines. Although current data from international studies suggest that rheumatic diseases are associated with a higher risk of COVID-19 infection and worse outcomes, there is limited literature in Saudi Arabia. This study aims to evaluate the outcomes and length of hospital stay of COVID-19 patients with inflammatory rheumatic diseases in Saudi Arabia. MethodThis was a single-center retrospective cohort study that included 122 patients with inflammatory rheumatic diseases and documented coronavirus disease 2019 (COVID-19) infection from 2019 to 2021. Patients with suspected COVID-19 infection, non-inflammatory diseases, such as osteoarthritis, or inflammatory diseases but without or with weak systemic involvement, such as gout, were excluded. ResultsThe vast majority (81.1%) of the patients were females. Rheumatoid arthritis was the most common primary rheumatological diagnosis. The admission rate was 34.5% with an overall mortality rate of 11.5%. Number of episodes of COVID-19 infection, mechanical ventilation, cytokine storm syndrome, secondary bacterial infection, number of comorbidities, rituximab, diabetes mellitus, hypertension, chronic kidney disease, and heart failure were significantly associated with a longer hospital stay. Additionally, hypertension, heart failure, rituximab, mechanical ventilation, cytokine storm syndrome, and secondary bacterial infection were significantly associated with higher mortality. Predictors of longer hospitalization were obesity, number of episodes of COVID-19 infection, mechanical ventilation, number of comorbidities, and chronic kidney disease, whereas, hypertension was the only predictor of mortality. ConclusionObesity, number of episodes of COVID-19 infection, mechanical ventilation, number of comorbidities, and chronic kidney disease were significantly associated with higher odds of longer hospitalization, whereas, hypertension was significantly associated with higher odds of mortality. We recommend that these patients should be prioritized for the COVID-19 vaccine booster doses, and rituximab should be avoided unless its benefit clearly outweighs its risk.
Objectives: To describes the epidemiology of cancer in patients with idiopathic inflammatory myopathies (IIM) treated at 2 tertiary centers in Riyadh, Saudi Arabia. Methods: This was a retrospective multi-center study evaluating the prevalence and the type of malignancy in an IIM population in King Saud University Medical City and King Abdulaziz Medical City between August 2017 to August 2018. Results: In total, 60 patients were included. Four had neoplasms (6.7%), 2 men had lymphoma, a woman had breast cancer and a second, ovarian cancer. Two patients died due to cancer or its complications. Older age (age >40 years), dysphagia, necrotic rash, absence of interstitial lung disease, high erythrocyte sedimentation rate and a negative anti Jo-1 antibody were potentially predictive risk factors for neoplasm. All patients diagnosed with cancer-associated myositis were investigated with routine and invasive modalities. Three of the 4 patients had abnormal findings in both modalities. One patient, the routine investigations were unremarkable, but a computed tomography of the pelvis revealed an ovarian mass that was subsequently diagnosed as malignant. Conclusion: An individualized approach might be more appropriate for high risk patients. Larger prospective studies are required to confirm the findings of the current study.
Sarcoidosis is an immune-mediated, inflammatory, non-caseating-granulomatous disease that can virtually infiltrate any organ. Cardiac sarcoidosis is a leading cause of death in patients with sarcoidosis. Its clinical presentation is highly heterogenous and unpredictable, ranging from asymptomatic to life-threatening conduction disturbances, such as ventricular arrhythmias, and heart failure. Herein, we report a case of isolated cardiac sarcoidosis presenting as sinus bradycardia with first-degree atrioventricular block and an episode of non-sustained polymorphic ventricular tachycardia in a 42-year-old male with non-ischemic cardiomyopathy. He was diagnosed by cardiac magnetic resonance imaging and positron emission tomography with fluorodeoxyglucose and treated with oral prednisone.
