Purpose: The prevalence and phenotype of capillaroscopic abnormalities in patients with autonomic nervous system dysfunction have not yet been investigated. Multiorgan involvement in dysautonomia entails abnormal vasoreactivity. We aim to correlate the diagnosis of autonomic dysfunction with certain clinical manifestations, which may provide prognostic or diagnostic information using a noninvasive technique, i.e., nailfold video capillaroscopy (NVC). Methods: Patients with autonomic nervous system dysfunction were recruited from rheumatology and neurology clinics with voluntary NVC procedures from 31 January 2024 to 10 January 2024, and a comparison with normal controls was performed. Additional recorded information include demographics and diagnoses of autonomic dysfunction types by autonomic testing, including, but not limited to, the following: reflex screen, sweat test, Valsalva maneuver, nerve fiber density, electromyography (EMG), serology, and history of autoimmune diseases. NVC was performed on a total of 27 patients. This study was approved by the Mayo Clinic Institutional Review Board. Results: The autonomic dysfunction group consisted of small-fiber neuropathy (37%), orthostatic hypotension (48%), autonomic neuropathy (30%), limited autonomic neuropathy (7%), postural orthostatic tachycardia syndrome (POTS) (7%), and connective tissue disease (7%), among other types. Patients with autonomic dysfunction had statistically significant increases in microhemorrhages, dilated capillaries, and ramifications when compared to controls. Conclusions: Autonomic dysfunction was associated with statistically significant microvascular abnormalities compared to normal controls with a distinct NVC pattern. There was a statistically significant correlation between age and BMI with microvascular abnormalities. Here, we demonstrate the diagnostic potential of NVC in autonomic dysfunction and advocate for further study of capillary structures in autonomic dysfunction.

Abstract Background/Aims Fibromyalgia has many unmet needs relating to treatment and delivery of effective and evidence-based healthcare is lacking. We analyzed social media conversations to understand patients’ perspectives of the lived experience of fibromyalgia, factors reported to trigger flares of pain, treatments being discussed; and identify barriers and opportunities to improve healthcare delivery. Methods A non-interventional retrospective analysis accessed detail rich conversations about fibromyalgia patients’ experiences with data curated from 400 million global documents and 714,000 documents, including a fibromyalgia language tag, between May 2019 and April 2021. Data were analyzed via qualitative and quantitative analyses. Results Fibromyalgia conversations were most numerous on Twitter and Reddit and conversations trends remained stable over time. There were numerous environmental and modifiable triggers ranging from (most frequently) stress and anxiety to various foods. Arthritis and irritable bowel syndrome (IBS) were the most frequently associated comorbidities. Patients with fibromyalgia reported a wide range of symptoms, with pain a cardinal feature. Massage, meditation and acupuncture domains were the most reported treatment modalities. Opportunities to improve healthcare delivered by medical providers were identified with current frustration relating to lack of acknowledgement of their disease, minimization of symptoms, and providers inadequately meeting their care needs. Conclusion We developed a comprehensive large-scale study which emphasizes advanced artificial intelligence algorithms application in real-world research design. Through the extensive encapsulation of patient perspectives, we have outlined habitual symptoms, triggers, and treatment modalities that provide a durable foundation to address gaps in healthcare provision.

Abstract Purpose The prevalence and phenotype of capillaroscopic abnormalities in patients with autonomic nervous system dysfunction has not been investigated. Multiorgan involvement in dysautonomia entails abnormal vasoreactivity. We aim to corelate the diagnosis of autonomic dysfunction with certain clinical manifestations that may provide prognostic or diagnostic information using a noninvasive technique: nailfold video capillaroscopy (NVC). Methods Patients with autonomic nervous system dysfunction were recruited from rheumatology and neurology clinic with voluntary NVC procedure from 1/31/24 to 10/1/24 and a comparison with normal controls was done. Additional information recorded includes demographics, diagnosis of type of autonomic dysfunction with autonomic testing including but not limited to reflex screen, sweat test, Valsalva maneuver, nerve fiber density, electromyography (EMG), serology, history of autoimmune disease.

Patient with autonomic dysfunction had statistically significant increased microhemorrhages, dilated capillaries and ramifications compared to controls. There was statistically significant correlation of age with capillary ramifications and BMI with capillary density and dilated capillaries.

There was statistically significant correlation of age and BMI with microvascular abnormalities. We demonstrate diagnostic potential of NVC in autonomic dysfunction and advocate for further study of capillary structure in autonomic dysfunction.

Background/Objective: To investigate the effect of mycophenolate mofetil (MMF) and rituximab (RTX) on pulmonary function test (PFT) results in a mixed cohort of patients with connective tissue disease-associated interstitial lung disease (CTD-ILD), longitudinally followed up for 1 year in a single academic center. Methods: Patients with CTD-ILD were identified in electronic medical records from 1 January 2009 to 30 April 2019. Prescribed MMF and RTX doses, dosage changes, and therapy plans were analyzed individually with improvement in PFT outcomes determined using multivariable linear regression models during 12-month follow-up. Results: Forty-seven patients with CTD-ILD, treated with MMF, RTX, or both, were included. Patients on combined MMF and RTX had worse PFT outcomes at baseline compared with patients on monotherapy. Substantial improvement was observed among all PFT outcomes from baseline to 12 months, regardless of medication dosage or therapy plans. The diffusing capacity of the lungs for carbon monoxide (DLCO) worsened by an average of 7.21 mL/(min*mmHg) (95% CI, 4.08–10.33; p < 0.001) among patients on RTX compared to combined therapy. Patients on higher doses of MMF at baseline experienced an average increase of 0.93 (95% CI, 0.04–1.82) units in DLCO from baseline to 6 months (p = 0.04) and a 2.79% (95% CI, 0.61–4.97%) increase in DLCO from 6 to 12 months (p = 0.02) within patients on concurrent RTX at 6-month follow-up. Conclusions: The treatment of CTD-ILD with MMF and/or RTX was associated with overall improvement in PFT outcomes. Combined therapy resulted in significant improvements in DLCO compared with monotherapy. Higher doses of MMF also provided greater improvements in DLCO.

Microvascular remodeling and capillary repopulation can occur after autologous hematopoietic stem cell transplant (HSCT) in patients with systemic sclerosis and systemic lupus erythematosus (SLE). We aim to report evidence for microvascular remodeling after autologous HSCT as observed by nailfold videocapillaroscopy (NVC). We describe a rare occurrence of features consistent with systemic sclerosis and SLE in a 33-year-old female with a complex clinical course refractory to conventional treatments, ultimately requiring autologous HSCT. We performed NVC before and after HSCT using optical video and light microscopy. At the microvascular level, morphologic changes in the capillary vascular bed were observed after HSCT. Pretransplant damage in capillary structure was noted as evidenced on NVC with architectural loss, ramifications, capillary drop, and decreased density. Posttransplant NVC revealed an increase in capillary density with evidence of microvascular remodeling. Further studies on the clinical use and impact of microvascular remodeling on disease progression are needed and looking into the application of NVC scoring to assess clinical response would be meaningful.

Takayasu arteritis is a chronic inflammatory vasculitis with granulomatous panarteritis particularly impacting large vessels including the aorta and its branches, especially the subclavian arteries, with clinical manifestation dependent on the involved artery. Sequelae of the active disease vary, including stenosis, occlusions, or aneurysmal dilatations of the large vessels. The prevalence of Takayasu arteritis is higher in the Asian population and in Japan, but quite low in the United States, varying from 0.9–8.4 per million people. Ocular manifestations are rare and lead to a delay in diagnosis and appropriate treatment. Ocular manifestations include Takayasu retinopathy, anterior ischemic optic neuropathy (AION), retinal artery occlusion (RAO) and retinal vein occlusion (RVO). We present two cases in which central retinal artery occlusion (CRAO) was associated with Takayasu arteritis. CRAO is an ophthalmic emergency with an incidence of 1.9 per 100,000 person years in the United States; only 5% of cases are arteritic, which can be observed with inflammatory vasculitides secondary to the formation of immune deposits.

Epstein-Barr virus (EBV) belongs to the group of human herpes virus and can cause clinical and subclinical infections. Although EBV-related disease presentations are similar, they can lead to oncogenic transformation with various clinical manifestations. A thorough workup with morphology, immunohistochemistry, and molecular studies is crucial for the diagnosis of EBV-positive polymorphic B-cell lymphoproliferative disorder, not otherwise specified (NOS), which is a new entity introduced by International Consensus Classification in 2022. We describe an interesting presentation of EBV-positive polymorphic B-cell lymphoproliferative disorder with laryngeal involvement to bring awareness to this entity and we would like to address the need for more accessible treatment options.
