Acute Pancreatitis Induced by Linagliptin: A Rare but Dangerous Side Effect

Diabetes mellitus type 2 (DMT2) is a highly prevalent disease both in the United States and worldwide. Multiple treatment options are currently available, and several new groups of medications have been introduced over the last couple of decades. One of these groups is dipeptidyl peptidase-4 (DPP-4) inhibitors. These medications have side effects, some of which are severe and potentially life-threatening; however, some of their side effects have been underreported since they are relatively new. When prescribing these medications, it is essential to be cautious, especially with patients at an increased risk of developing an adverse effect. We present the case of a 57-year-old male who developed DPP-4 inhibitor-induced acute pancreatitis after the initiation of linagliptin. The patient did not have any apparent risk factors for pancreatitis as he did not drink alcohol or smoke cigarettes, his lipid panel was within normal limits, and he had a cholecystectomy five years prior. His linagliptin was held in the hospital and discontinued post-discharge, which led to the resolution of his symptoms.

Lung Adenocarcinoma Presenting as Malignant Pericardial Effusion/Tamponade

Lung cancers are the most common primary tumors that involve the pericardium with a prevalence of up to 50%. Usually, pericardial involvement goes undetected with almost 10%-12% found among all cancer related autopsies. Rarely pericardial effusions can be the initial site of metastasis and initial manifestation of a primary tumor. In our case, we report a 57-year-old female presenting with cardiac tamponade and subsequent testing was done which revealed lung adenocarcinoma. Malignant pericardial effusions are often silent, but certain times can present with symptoms of shortness of breath, chest pain, cough, arrhythmias, and rarely as pericardial tamponade. A high index of suspicion is required when a patient presents with tamponade to diagnose malignancy. Emergent pericardiocentesis may be warranted depending on the clinical presentation but quite often, patients tend to have a poor prognosis despite therapy given the extent of disease.

Multiomics Analysis and Systems Biology Integration Identifies the Roles of IL-9 in Keratinocyte Metabolic Reprogramming

IL-9‒producing T cells are present in healthy skin as well as in the cutaneous lesions of inflammatory diseases and cancers. However, the roles of IL-9 in human skin during homeostasis and in the pathogenesis of inflammatory disorders remain obscure. In this study, we examined the roles of IL-9 in metabolic reprogramming of human primary keratinocytes (KCs). High-throughput quantitative proteomics revealed that IL-9 signaling in human primary KCs disrupts the electron transport chain by downregulating multiple electron transport chain proteins. Nuclear magnetic resonance-based metabolomics showed that IL-9 also reduced the production of tricarboxylic acid cycle intermediates in human primary KCs. An integration of multiomics data with systems-level analysis using the constraint-based MitoCore model predicted marked IL-9-dependent effects on central carbohydrate metabolism, particularly in relation to the glycolytic switch. Stable isotope metabolomics and biochemical assays confirmed increased glucose consumption and redirection of metabolic flux toward lactate by IL-9. Functionally, IL-9 inhibited ROS production by IFN-γ and promoted human primary KC survival by inhibiting apoptosis. In conclusion, our data reveal IL-9 as a master regulator of KC metabolic reprogramming and survival.

An Emotion Care Model using Multimodal Textual Analysis on COVID-19

At the dawn of the year 2020, the world was hit by a significant pandemic COVID-19, that traumatized the entire planet. The infectious spread grew in leaps and bounds and forced the policymakers and governments to move towards lockdown. The lockdown further compelled people to stay under house arrest, which further resulted in an outbreak of emotions on social media platforms. Perceiving people's emotional state during these times becomes critically and strategically important for the government and the policymakers. In this regard, a novel emotion care scheme has been proposed in this paper to analyze multimodal textual data contained in real-time tweets related to COVID-19. Moreover, this paper studies 8-scale emotions (Anger, Anticipation, Disgust, Fear, Joy, Sadness, Surprise, and Trust) over multiple categories such as nature, lockdown, health, education, market, and politics. This is the first of its kind linguistic analysis on multiple modes pertaining to the pandemic to the best of our understanding. Taking India as a case study, we inferred from this textual analysis that 'joy' has been lesser towards everything (~9-15%) but nature (~17%) due to the apparent fact of lessened pollution. The education system entailed more trust (~29%) due to teachers' fraternity's consistent efforts. The health sector witnessed sadness (~16%) and fear (~18%) as the dominant emotions among the masses as human lives were at stake. Additionally, the state-wise and emotion-wise depiction is also provided. An interactive internet application has also been developed for the same.

Prediction modelling of COVID using machine learning methods from B-cell dataset

Coronavirus is a pandemic that has become a concern for the whole world. This disease has stepped out to its greatest extent and is expanding day by day. Coronavirus, termed as a worldwide disease, has caused more than 8 lakh deaths worldwide. The foremost cause of the spread of coronavirus is SARS-CoV and SARS-CoV-2, which are part of the coronavirus family. Thus, predicting the patients suffering from such pandemic diseases would help to formulate the difference in inaccurate and infeasible time duration. This paper mainly focuses on the prediction of SARS-CoV and SARS-CoV-2 using the B-cells dataset. The paper also proposes different ensemble learning strategies that came out to be beneficial while making predictions. The predictions are made using various machine learning models. The numerous machine learning models, such as SVM, Naïve Bayes, K-nearest neighbors, AdaBoost, Gradient boosting, XGBoost, Random forest, ensembles, and neural networks are used in predicting and analyzing the dataset. The most accurate result was obtained using the proposed algorithm with 0.919 AUC score and 87.248% validation accuracy for predicting SARS-CoV and 0.923 AUC and 87.7934% validation accuracy for predicting SARS-CoV-2 virus.

Manufacturing Considerations for the Development of Lipid Nanoparticles Using Microfluidics

In the recent of years, the use of lipid nanoparticles (LNPs) for RNA delivery has gained considerable attention, with a large number in the clinical pipeline as vaccine candidates or to treat a wide range of diseases. Microfluidics offers considerable advantages for their manufacture due to its scalability, reproducibility and fast preparation. Thus, in this study, we have evaluated operating and formulation parameters to be considered when developing LNPs. Among them, the flow rate ratio (FRR) and the total flow rate (TFR) have been shown to significantly influence the physicochemical characteristics of the produced particles. In particular, increasing the TFR or increasing the FRR decreased the particle size. The amino lipid choice (cationic-DOTAP and DDAB; ionisable-MC3), buffer choice (citrate buffer pH 6 or TRIS pH 7.4) and type of nucleic acid payload (PolyA, ssDNA or mRNA) have also been shown to have an impact on the characteristics of these LNPs. LNPs were shown to have a high (>90%) loading in all cases and were below 100 nm with a low polydispersity index (≤0.25). The results within this paper could be used as a guide for the development and scalable manufacture of LNP systems using microfluidics.

Anaemia in patients with type 2 diabetes mellitus without nephropathy is related to iron deficiency

BACKGROUND AND AIMS

Iron deficiency anaemia, although well reported in diabetic nephropathy, has not been well studied in type 2 diabetes patients in the absence of nephropathy. We studied the prevalence of anaemia and iron deficiency in type 2 diabetes patients without nephropathy.

MATERIAL AND METHODS

A total of 89 patients were selected for this study. 24 h urine protein less than 500 mg was used as the criteria to rule out diabetic nephropathy. Complete hemogram, iron profile and high sensitivity C reactive protein (hs CRP) levels were performed in each patient.Functional iron deficiency (FID) was defined as serum ferritin more than 100 μg/l with serum transferrin less than 20% and total iron deficiency state was defined as serum ferritin less than 100 μg/l.

RESULTS

Fifteen patients (16.8%)had anaemia out of which 13 had total iron deficiency and one each had functional iron deficiency and normal iron status respectively. Assessment of the iron status overall showed that 49 patients had TID (55.05%), 16 had FID (17.9%)and 24 (27.05%) had normal iron status. The hs-CRP was significantly higher in those with iron deficiency.

CONCLUSIONS

The present study found a high prevalence of iron deficiency anaemia in type 2 diabetic patients even in the absence of nephropathy. Most of the diabetic subjects also displayed an iron deficiency state the cause of which needs further investigation.

Obesity, Sarcopenia, and Outcomes in Non-Small Cell Lung Cancer Patients Treated With Immune Checkpoint Inhibitors and Tyrosine Kinase Inhibitors

Body composition refers to the proportional content of body fat mass and lean body mass that can lead to a continuum of different phenotypes ranging from cachectic/sarcopenic state to obesity. The heterogenetic phenotypes of body composition can contribute to formation of some cancer types and can sometimes lead to disparate outcomes. Both of these extremes of the spectrum exist in patients with non-small cell lung carcinoma (NSCLC). The discovery of new pathways that drive tumorigenesis contributing to cancer progression and resistance have expanded our understanding of cancer biology leading to development of new targeted therapies including tyrosine kinase inhibitors (TKI) and immune checkpoint inhibitors (ICI) that have changed the landscape of NSCLC treatment. However, in the new era of precision medicine, the impact of body composition phenotypes on treatment outcomes and survival is now being elucidated. In this review, we will discuss the emerging evidence of a link between body composition and outcomes in patients with NSCLC treated with TKI and ICI. We will also discuss suggested mechanisms by which body composition can impact tumor behavior and anti-tumor immunological response.

Accidental Central Venous Catheter Placement in the Internal Thoracic Vein: A Case Report

Central venous catheter (CVC) placement is an essential component of critical care medicine. CVC malposition is a known complication of internal jugular vein (IJV) cannulation. However, catheterization of the internal thoracic vein (ITV) is much rarer. Only a handful of case reports have been documented, and guidelines for management are therefore lacking. Our case study describes this rarely occurring ITV cannulation along with the discussion of risk factors, warning signs of malpositioning, and subsequent management plans to optimize patient safety. Previous studies have used fluoroscopy and agitated saline flush tests to confirm that agents administered through an ITV-located catheter would reach the right atrium. Considering this, it would follow that a catheter in this site could theoretically be used for medication administration, especially in emergency settings. This hypothesis remains the most novel part of our case study and might prompt further exploration of management strategies in this particular situation.

Cross-sectional area reference values of the median nerve at the palm using ultrasound

BACKGROUND

The most common neuromuscular ultrasound abnormality in carpal tunnel syndrome is enlargement of the median nerve near the distal wrist crease, but sometimes the median nerve enlarges in the palm, just distal to the transverse carpal ligament. This study was conducted to devise a protocol for measuring the median nerve in the palm and to generate reference values for nerve cross-sectional area at this site.

METHODS

A systematic protocol was developed, 30 healthy individuals underwent ultrasound of the median nerve in the palm bilaterally, and cross-sectional area was recorded.

RESULTS

The mean cross-sectional area of the median nerve at the palm was between 11.4 mm² (95% confidence interval [CI] [10.4,12.4]) and 11.6 mm² (95%CI [10.6,12.6]).

CONCLUSIONS

The median nerve can be measured just distal to the hook of the hamate in the palm, and the mean cross-sectional area at this site is slightly larger than it is at the distal wrist crease.

Delayed Recurrence of Chromophobe Renal Cell Carcinoma Presenting as Metastatic Duodenal Ulcer

Renal cancers are one of the common causes of cancer-related morbidity and mortality worldwide. Most primary cases are localized at presentation and are treated with partial or radical nephrectomy with curative intent. However, renal cell carcinoma (RCC) is known for its potential recurrence, sometimes several years after initial management. Many of these recurrent cases commonly metastasize to the liver, kidney, or bone and herald a poor prognosis. We present a case study of nonclear cell RCC, which recurred 33 years after nephrectomy and masqueraded as a duodenal ulcer -- an extremely rare site for metastasis. This is unique as it describes a presentation only sparingly documented in the medical literature and highlights a more extended period of recurrence than currently reported. Moreover, our patient’s tumor was chromophobe cell variety, a rare sub-type of nonclear cell RCC, which to our knowledge has never been known to cause duodenal metastasis. Studies have implicated a prognostic role of lymph node involvement at the time of initial diagnosis to predict future recurrence. This case is a drop in the mighty ocean to prompt further investigation on the utility of life-long surveillance protocols and further research evaluating the role of lymph node dissection in preventing such recurrences and high mortality. 

Vaping-Induced Lung Injury: An Uncharted Territory

Vaping-associated lung injury (VALI) presents with symptoms ranging from lower respiratory tract involvement (shortness of breath, fever, and cough) to gastrointestinal involvement (vomiting and diarrhea). Based on the longitudinal analysis, VALI is associated with increased risk for respiratory disease, making it paramount for medical professionals to understand this disease process and be familiar with its varied presentations. Our case study is a presentation of two relatively young patients with VALI, with a varied clinical course and distinct levels of severity. VALI still remains uncharted territory. Case reports, such as ours, have the potential to invoke randomized controlled clinical trials to better understand the disease etiology, pathology, and management.

Calcifying Fibrous Tumor Complicated by Empyema

Calcifying fibrous tumor (CFT) is a rare, benign proliferation of fibroblasts and inflammatory cells that is non-invasive and usually arises in deep tissue structures. Due to its overall paucity, no accurate incidence has been reported yet. We understand this disease via a handful of case studies published in the medical literature, first of them being from 1988. Earlier known as 'pseudotumor', it was recently given its name due to the potential of recurrence and multifocal involvement. We describe the case of a 43-year-old Hispanic male who presented with a large symptomatic pleural-based mass which turned out to be CFT and was later complicated by empyema. Our aim is to increase awareness about this rare disease and throw light upon its benign nature, despite an alarming and suspicious appearance on imaging. Due to the large size of our patient’s mass (largest reported yet), he needed extensive chest wall reconstruction, leading to complications requiring additional invasive procedures. This underscores the importance of early diagnosis and treatment which can reduce the need for aggressive surgical manipulation and avoid postoperative complications, thereby providing high-value care. Treating physicians should be mindful of this, in order to prompt early recognition to ensure effective patient care.

SAT0319 SUBCLINICAL ATHEROSCLEROSIS IN INDIAN PATIENTS WITH SCLERODERMA – CLINICAL AND SEROLOGICAL ASSOCIATIONS

Background:

Scleroderma has been associated with increased risk of cardiovascular events, however,studies on this from India are sparse.We evaluated clinical and serological factors associated with subclinical atherosclerosis in Indian patients with scleroderma, in a cross-sectional design.

Objectives:

To compare carotid intima-medial thickness (CIMT, mean value of both carotids) as a measure of subclinical atherosclerosis (SCA) between patients with scleroderma (n=61) fulfilling 2013 ACR/EULAR criteria, and healthy controls (n=41).

- To compare clinical (body mass index – BMI, waist-hip ratio – WHR, fasting lipid profile) and serological factors (microparticles, endothelial microparticles, inflammatory cytokines associated with increased cardiovascular risk) between patients with scleroderma and healthy controls.

- To identify factors associated with SCA in scleroderma patients.

Methods:

Subclinical atherosclerosis(SCA) was defined by presence of carotid plaques, or increased CIMT >2 standard deviations compared with Indian reference standards for age and sex. Total microparticles (TMP) were measured of plasma after ultracentrifugation as per previously described protocol using microbeads of 3 μm size (TMP were of size 0.1-1 μm); of these, microparticles positive for CD31 and CD142 were endothelial microparticles (EMP). Serum cytokines (IL-1, IL-6, TNF-α, IL-17) were measured by ELISA using manufacturer instructions. Linear regression was used to identify the determinants of CIMT in scleroderma. Binomial logistic regression was used to identify factors associated with subclinical athersclerosis in scleroderma.

Results:

Despite lower BMI, triglycerides and VLDL cholesterol, CIMT was significantly higher in patients with scleroderma. Patients with scleroderma had significantly higher total microparticles and endothelial microparticles in plasma, and serum IL-1± and IL-6 (Table 1). On multivariable regression, age was the only significant determinant of CIMT. 28 (45.9%) patients had SCA; 13 (21.3%) had carotid plaques. Patients with SCA had higher proportion of males (9/28 in those with SCA vs 2/33 in those without SCA). Binomial logistic regression did not identify any other significant predictors of SCA.

AB1169 RHEUMATOLOGY PATIENT PERCEPTION OF CARDIOVASCULAR RISKS: A SURVEY AT A TEACHING HOSPITAL

Background:

It is well known that individuals with rheumatological conditions are at an increased risk for developing cardiovascular diseases (CVS) and they are the most common cause of mortality. However, there is still lack of awareness about the CVS risk among Rheumatology patients. We carried out a patient survey to assess their awareness and perception of CVS risk associated with their condition. We also assessed if the health professionals attending to these patients gave adequate education to the patients regarding the CVS risk.

Objectives:

To study awareness about CVS risks among rheumatology patients

Methods:

This was a prospective cross sectional survey where in multiple-choice questionnaires were distributed to consecutive patients attending rheumatology clinic. The questionnaire contained 18 questions including demographics, diagnosis, medications and their awareness of cardiovascular risks associated with their underlying rheumatic conditions. We also explored as patient attempted any Primary preventive measures for reducing the CVS risk.

Results:

We collected data of 57 patients with 47% of patients were above 60 years of age with Female: Male ratio of 3:1. Rheumatoid arthritis was the most common diagnosis (60%) with others including AS (22%), SLE(5%). 32% of patients had been suffering from inflammatory disorder for >10 years and 44% believed their disease was still not fully controlled. 37% had family history of heart diseases.

More than half of the patients (56%) were unaware of cardiovascular risks associated with their condition and 65% overall reported that they were not personally informed about these risks by the treating health professionals. When we analysed the newly diagnosed patients (<5years) 64% were unaware about the CVS risks which is higher compared to patients with diagnosis of >5 years. We tried to explore any ethnic differences, however the number is too small to compare. We noted that around 60% of white British with rheumatological diagnosis were not aware of CVS risk in our group. When further asked about the primary preventive measures, only 23% engage in exercise, 21% have made diet changes, 12% take aspirin, 16% have quit smoking and only 5% quit alcohol.

Conclusion:

This was a small pilot study to look at the patient awareness of CVS risks associated with rheumatological conditions. Clearly there is lack of awareness among patients about CVS risks. Furthermore, most of the patients reported they were not educated about the risks from the health professionals. Majority do not engage in any kind of primary preventive measure for heart diseases. It is crucial that the health professionals actively educate patients regarding the CVS risks and the various methods through which these can be prevented. We believe patient-targeted educational programmes and behavioural interventions can be incorporated for holistic patient management.

AB0694 IS THERE ANY HETEROGENEITY OF SPONDYLOARTHRITIS DISEASE MANIFESTATIONS BETWEEN TWO ETHNIC SUBGROUPS?:A MULTICENTRE INTERNATIONAL COMPARATIVE STUDY BETWEEN INDIA AND UK

Background:

Pathogenesis of Spondyloarthritis (SpA) multifactorial and remains unclear. Various hypothesis have been postulated genetics, HLAB27, IL17, Gut microbiome and Biomechanical stress. Many of these factors can be attributed to ethnic background and environment. HLAB27 accounts for 20–25 % of total heritability and 40% of genetic risk while <10% of HLA-B27 carriers in general population develop SpA1. Higher faecal calprotectin levels in SpA compared to control point towards microscopic gut inflammation2. Thus dietary habits and geographical factors can influence pathogenesis of disease. We looked in clinical manifestations of SpA patients of two very different ethnic background Caucasians and Indians from UK and India to shed more light in understanding the disease

Objectives:

To study any differences in the clinical manifestations of SpA patients of two ethnic groups

To compare outcome measure (BASDAI and ASDAS) between Caucasians and Indians

To study the difference in disease activity between Indian patients and British Asians

Methods:

Multicentre observation study where data of SpA patients attending rheumatology clinics from two major teaching hospitals collected. In India data collected from Sheth VS Hospital and NHL Medical College, Gujarat and in United Kingdom from University Hospitals Leicester, NHS trust. Leicester has a multi-ethnic demography wherein almost 30%3of population is of south Asian ethnicity, making this study unique.

Baseline demographic and clinical data was collected. Clinical and outcome measures compared to see any heterogeneity in disease manifestations. SPSS software used

Results:

Total 200 patients analysed with 148 Indians and 52 Caucasians. The Indian cohort was subdivided into British Asians (second generation Indians) and those form Gujarat, India

We found Indian subgroups were younger with shorter disease duration. Comparison in Table 1

Conclusion:

We found Caucasians had more HLAB27 positivity and extra-articular manifestation of uveitis however the Indian population has more enthesitis and peripheral arthritis. Enthesitis is initiated during a mechano-sensation and the cultural difference including style of footwear could probably be one of the factors explaining our findings inflammatory back pain has been reported to be higher in Indians compared to Caucasians which could be due to life style

The fact that ASDAS CRP behaves similarly in Indian patients across the two countries and is more when compared to Caucasians might point towards overall higher burden of disease in Indian population

To our knowledge this is a first study comparing clinical manifestations of SpA between Indians and Caucasians

AB0953 CANNABINOIDS: FRIEND OR FOE OR A BYSTANDER?

Background:

Cannabinoids has recently gained popularity for use in chronic pain. There is a lot of inquisitiveness among our patients wherein health care professionals are asked about its efficacy, side effects and sometimes even ask for a prescription! As there is paucity of data and research about its use in rheumatology, patient reported outcome(PROM) can guide ahead in expanding our knowledge and experience.

Objectives:

To study usage of cannabinoids by rheumatology patients

To study awareness among primary physicians regarding Cannabinoid usage in rheumatology.

Methods:

Cross sectional survey with two arms. Arm 1 Information from patients attending tertiary rheumatology clinic,including perception regarding the use of Cannabinoids.

Arm 2 consisted of collecting data via web-based survey with20-question from 100 GPs of Leicestershire. Questions on demographics, perspectives on and knowledge of cannabinoid use. Statistical analysis SPSS software.

Results:

Arm1 Total 102 rheumatology patients with 60%were females and 45% secondary education. 48% were unemployed. 75% Caucasians, 18% Asians. RA most common diagnosis followed by OA and FMS. 40 % depression and anxiety in addition to Rheumatic disease. 94% reported ongoing pain with 6-8 on a VAS scale. 79% were satisfied with their current therapy. 65% had heard about complementary medicine and 15% reported using cannabinoids.

Most common form Cannabinoids oil 60% followed by smoking 20%. 56% reported using >3 months and majority 72% use daily. Median age 55 years. 88% users Caucasians. Mean disease duration 6.25 years among users indicates chronicity of disease has a direct proportion in usage. All users had ongoing pain of 7 on VAS. 87% believed it helps them managing pain effectively with a pain free state. On an average spends between 50-100 pounds per week. More than half believe cannabinoids should be available as a prescription drug in NHS and 30% interested to know more about it.

In Arm 2 consisting of Primary care physicians, response rate 50%. Average clinical experience 5 years. Only 20% heard about usage of complementary medicine by rheumatology patient. Most replied that 10% of their patients use Cannabinoids for pain management. Most did not believe use of cannabinoids benefited the patients. Only 4% recommend its usage. 25% think it should be available as prescription. 40% experienced patients asking about cannabinoids during appointment. 88% of respondents did not know much about cannabinoid usage in rheumatology and have never prescribed it in their practice.

Conclusion:

Cannabinoids widely used by the rheumatology patients with PROM favouring its efficacy for control of chronic pain. Preclinical data suggest that cannabinoids might have a therapeutic potential RA1, OA, FMS2. Clinical data regarding cannabinoid treatment for rheumatic diseases are scarce, therefore, recommendations concerning cannabinoid treatment cannot be made. All patients who reported using it suffered from moderate to severe chronic pain. Thus main indication of usage was pain rather than recreational purpose. Although a small survey it clearly highlights lack of knowledge among primary physicians. These results emphasise the need for further research regarding the benefits and risks of cannabinoids in rheumatology.

C00006 PSYCHOLOGICAL IMPACT OF COVID 19 PANDEMIC ON PATIENTS WITH RHEUMATOLOGICAL DISORDERS - A WEB BASED CROSS-SECTIONAL MULTICENTRE SURVEY

Background:

The COVID-19 pandemic has resulted in uncertainty and negative psychological outcomes for patients with autoimmune rheumatic diseases for several reasons.1The anxiety is due to “underlying conditions” that are expected to increase the risk of infection and / or severe complications. Patients with rheumatological disorders fall into this group as they are believed to be immunosuppressed due to disease or the treatment. It is essential to understand the level of anxiety among the rheumatic disease patients at the current situation of COVID-19.

Objectives:

To study difference in Anxiety score (Mean/Avg Score) among following groups-underlying rheumatic disease, age, gender, marital status, educational status, employment status, medications, those who were on steroids/not, those who are Biologicals / Not.

Methods:

A web-based cross-sectional multi-centre survey was done across 5 rheumatology centres in India. The study duration was between 9th May and 16th May 2020.The questionnaire included consent, demographic details, medication history, opinion about tele rheumatology services and anxiety score measured by Beck Anxiety Inventory (BAI)2.

Results:

The survey was sent to 2987 patients, there were 933 responses and 581 were complete (Male =175). Complete responses were considered for data analysis. Most respondents were less than 50 years of age (70.6%). Rheumatoid arthritis (RA) was the most frequent (50.6%) diagnosis followed by other conditions. Most of the patients (43%) were on combination DMARD therapy, 12.7% of patients were on biological drugs and 23.9% of patients were on glucocorticoids. Statistically significant higher anxiety scores were observed in females, patients suffering from fibromyalgia, patients on glucocorticoids and biological agents. There was no difference in the anxiety scores with regard to age, educational status, and employment status.Difficulty in meeting rheumatologists and getting medications was expressed by 327 (56.2%) and 73 (29.7%) respondents respectively. Majority of respondents (86.6 %) agreed/strongly agreed regarding use of telemedicine to access health care during the crisis.

Conclusion:

The findings of the study revealed that anxiety is a major concern in patients with autoimmune rheumatic diseases. Fibromyalgia patients and those who were on glucocorticoids and biological drugs were found to have more anxiety levels compared to other groups of patients. In such periods of public health crises, telemedicine is a great tool for patients to access healthcare without fear of going to hospital. There is a need to intensify the awareness and address the mental health issues of rheumatology patients during this COVID-19 pandemic.

AB1030 IgG4-RELATED DISEASE: A RETROSPECTIVE CLINICAL CASE SERIES FROM A TERTIARY CARE CENTRE IN INDIA

Background:

IgG4-related disease (IgG4-RD) is an often unrecognized, rare fibro-inflammatory condition that can involve various organ systems.

Objectives:

The aim of this study was to identify the different clinical patterns of this disease in a single centre in North India.

Methods:

70 patients were diagnosed on the basis of published diagnostic criteria for IgG4-RD. Patients’ presenting complaints, epidemiological profiles, laboratory, radiological and histological findings along with the treatment and outcomes were collated and analyzed from 2011 – 2019.

Results:

In a total of 70 patients who were diagnosed with the disease, the ratio of female to male ratio was 1:1. The mean age of patients was 41.4 years. Involvement of orbits and peri-orbital tissues was highest (52.9%) due to large number of referrals from ophthalmology services. 13% of patients had multiple organ involvement. Patients with involvement of retroperitoneal tissues and lymph nodes were 8.5% and 5.7%, respectively. Increased serum IgG4 levels were found in 74.3% of the patients. Histopathological examinations of the affected organs were performed in 44 (62.85%) patients and a diagnosis of possible (38.57), probable (32.85%) and definite (28.57%) IgG4-RD was made. Majority of the patients (94.3%) required immunosuppressive medications along with corticosteroids. Azathioprine was the most commonly used (72.8%) immunosuppressive medication. Rituximab was used in17.1% of the patients, of whom one had multisystem involvement.

Conclusion:

This study depicts the most common patterns of organ involvement along with the epidemiological, laboratory, histological, radiological data and response to treatment, in IgG4-RD, with a definite ophthalmology referral bias, in a tertiary care centre in North India.

Pulmonary Embolism in COVID-19 and the Unanswered Questions

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has ravaged the global society as we know it. As almost a dozen pharmaceutical agents go into randomized controlled clinical trials, multiple studies have surfaced trying to associate a hypercoagulable state to coronavirus disease 2019 (COVID-19) patients. We report two COVID-19 cases who presented with occlusive pulmonary embolism (PE) strongly supporting a hypercoagulable state incurred by SARS-CoV-2. This is significant as it is one of the early reports of such an initial presentation of COVID-19 in the USA. Through our report, we invite the medical community to share a perspective about long-term management guidelines for SARS-CoV-2 associated venous thromboembolism (VTE) and prompt future research.
