Rapid disease progression after enzyme replacement therapy interruption in a patient with cholesteryl ester storage disorder

Lysosomal acid lipase deficiency (LALD) has two clinical phenotypes: an infantile-onset form - Wolman disease (WD) presented by severe malabsorption, cholestasis, malnutrition, hepatosplenomegaly and early death, and a later-onset form - cholesteryl ester storage disorder (CESD) with hepatosplenomegaly, dyslipidemia, malabsorption and variable disease severity manifestation. Enzyme replacement therapy (ERT) with sebelipase alfa was approved by the Brazilian Health Regulatory Agency (ANVISA) in 2017. We report the deleterious effect of ERT interruption in a CESD patient. Male, 16y, diagnosed at 7y, positive familiar history with mother, grandfather and three siblings affected. He was enrolled in the phase 3 clinical trial from age 9-12y under the 3 mg/Kg dose regimen. Then he enrolled in the post-study donation program under the same dose. Due to personal, importation and supply issues, and the COVID-19 pandemic restrictions, he had a progressive decrease in treatment adherence rate: 68% at 12y, 27% at 13y, 30% at 14y and after that he had an interruption of 1 entire year. At 15y he presented with generalized edema, severe fatigue, tachycardia, was hospitalized, diagnosed low serum iron, albumin and protein, acute anemia (hemoglobin: 6.2 g/dL - normal range of 12,5-13,5), and received blood transfusion. In the next year, still without ERT, he was hospitalized again due to generalized edema, acute anemia (Hemoglobin = 6.9 g/dL) and worsening of hypoalbuminemia and iron deficiency, and received blood transfusion. Although our patient has the CESD phenotype, the ERT interruptions did not worsen the liver involvement nor the dyslipidemia, but caused a severe malabsorption which is classically described in WD phenotype. In conclusion, this case serves as an alert that when ERT is interrupted, there is a rapid clinical deterioration.

Pneumopericardium in COVID-19 Infection

Pneumopericardium is a rare medical condition that occurs following trauma, surgery, or other medical interventions. The presence of pneumopericardium after COVID-19 pneumonia has been reported in some cases, and it has been explained that most cases could be self-limited. Here, we describe a 51-year-old man afflicted by pneumopericardium with COVID-19 infection. The patient had pneumopericardium and massive pericardial effusions, necessitating surgical strategies such as pericardial windows. This case highlights the potential severity of COVID-19. We also suggest that cardiologists pay attention to the possibility of pneumopericardium in cases with COVID-19 infection. © 2023, Iranian Heart Association. All rights reserved.

PATHOMORPHOLOGICAL FEATURES OF ACUTE RESPIRATORY DISTRESS SYNDROME IN COMPETING LUNG DISEASES: COVID-19 AND SARCOIDOSIS

The COVID-19 pandemic is a worldwide problem. The clinical spectrum of SARS-CoV-2 infection varies from asymptomatic or paucity-symptomatic forms to conditions such as pneumonia, acute respiratory distress syndrome and multiple organ failure. Objective was to describe a clinical case of SARS-CoV-2 infection in the patient with sarcoidosis and cardiovascular pathology developing acute respiratory syndrome and lung edema. Material and methods. There were analyzed accompanying medical documentation (outpatient chart, medical history), clinical and morphological histology data (description of macro- and micro-preparations) using hematoxylin and eosin staining. Results. Lung histological examination revealed signs of diffuse alveolar damage such as hyaline membranes lining and following the contours of the alveolar walls. Areas of necrosis and desquamation of the alveolar epithelium in the form of scattered cells or layers, areas of hemorrhages and hemosiderophages are detected in the alveolar walls. In the lumen of the alveoli, a sloughed epithelium with a hemorrhagic component, few multinucleated cells, macrophages, protein masses, and accumulated edematous fluid were determined. Pulmonary vessels are moderately full-blooded, surrounded by perivascular infiltrates. Signs of lung sarcoidosis were revealed. Histological examination found epithelioid cell granulomas consisting of mononuclear phagocytes and lymphocytes, without signs of necrosis. Granulomas with a proliferative component and hemorrhage sites were determined. Giant cells with cytoplasmic inclusions were detected — asteroid corpuscles and Schauman corpuscles. Non-caseous granulomas consisting of clusters of epithelioid histiocytes and giant Langhans cells surrounded by lymphocytes were detected in the lymph nodes of the lung roots. Hamazaki–Wesenberg corpuscles inside giant cells were found in the zones of peripheral sinuses of lymph nodes. In the lumen of the bronchi, there was found fully exfoliated epithelium, mucus. Granulomas are mainly observed subendothelially on the mucous membrane, without caseous necrosis. Histological examination of the cardiovascular system revealed fragmentation of some cardiomyocytes, cardiomyocyte focal hypertrophy along with moderate interstitial edema, erythrocyte sludge. Zones of small focal sclerosis were determined. The vessels of the microcirculatory bed are anemic, with hypertrophy of the walls in small arteries and arterioles. Virological examination of the sectional material in the lungs revealed SARS-CoV-2 RNA. Conclusion. Based on the data of medical documentation and the results of a post-mortem examination, it follows that the cause of death of the patient R.A., 50 years old, was a new coronavirus infection COVID-19 that resulted in bilateral total viral pneumonia. Сo-morbidity with competing diseases such as lung sarcoidosis and cardiovascular diseases aggravated the disease course, led to the development of early ARDS and affected the lethal outcome.

CONSEQUENCES OF DISCONTINUING ANTIHYPERTENSIVE TREATMENT DURING THE FIRST WAVE OF A COVID-19 PANDEMIC

Arterial hypertension (AH), especially insufficiently and inadequately treated, is a disease with serious morbidity-mortality consequences. AH was the most common comorbidity in patients with COVID-19 infection. During the first wave of the COVID-19 pandemic, Slovakia has low number of COVID 19 patients. However, worldwide was reported 2-fold higher mortality in COVID 19 positive patients with untreated AH compared to patients with treated AH. Many patients have discontinued antihypertensive treatment due to changes in access to healthcare as well as the dissemination of unverified information. The aim of our study was to evaluate the AH treatment in patients during the first wave of the COVID-19 pandemic, to analyze the consequences of changes in AH treatment. It is a retrospective analysis of antihypertensive treatment of patients followed in the tertiary center. A total of 112 consecutive patients with AH who had a scheduled follow-up during the months of March-April 2020 were included. A telephone check-up was performed 6 months after the scheduled follow-up. These were patients with a mean age of 64 ± 18.1 years, 73 patients (65.2%) were male, and the mean number of antihypertensives per patient was 3.6 ± 2.2 drugs. Out of a total of 112 patients, 9 (8%) patients completely discontinued AH treatment, 15 (13.4%) patients discontinued ACEI / ARB without substitution, 5 (4.5%) patients discontinued ACEI / ARB with subsequent AH adjustment treatment. In the observed period March-April 2020, patients with newly diagnosed AH were absent. In our followed patient population (1.8%) were tested as COVID positive, 0 patients were hospitalized for COVID 19 infection. 4 (16,7%) patients overcame stroke, 1 (4.2%) patient overcame TIA, 1 (4.2%) was hospitalized for ACS, 2 (8.3%) for AF with rapid ventricular response, 2 (8.3%) for pulmonary edema, 2 (8.3%) patients died. In the group of patients who had adjusted treatment or did not discontinue AH treatment (a total of 88 patients) 1 (1.1%) patient overcame stroke, 1 (1.1%) was hospitalized for ACS, 1 (1.1%) for newly diagnosed AF, 1 (1.1%) patient died. Unjustified complete or partial discontinuation of antihypertensive treatment during the first wave of the COVID-19 pandemic has led to an increase in complications of arterial hypertension. Achieving BP targets should also be crucial during the COVID 19 pandemic.

Lung Injury in COVID-19 Has Pulmonary Edema as an Important Component and Treatment with Furosemide and Negative Fluid Balance (NEGBAL) Decreases Mortality.

The SARS-CoV2 promotes dysregulation of Renin-Angiotensin-Aldosterone. The result is excessive retention of water, producing a state of noxious hypervolemia. Consequently, in COVID-19 injury lung is pulmonary edema. Our report is a case-control study, retrospective. We included 116 patients with moderate-severe COVID-19 lung injury. A total of 58 patients received standard care (Control group). A total of 58 patients received a standard treatment with a more negative fluid balance (NEGBAL group), consisting of hydric restriction and diuretics. Analyzing the mortality of the population studied, it was observed that the NEGBAL group had lower mortality than the Control group, p = 0.001. Compared with Controls, the NEGBAL group had significantly fewer days of hospital stay (p < 0.001), fewer days of ICU stay (p < 0.001), and fewer days of IMV (p < 0.001). The regressive analysis between PaO2/FiO2BAL and NEGBAL demonstrated correlation (p = 0.04). Compared with Controls, the NEGBAL group showed significant progressive improvement in PaO2/FiO2 (p < 0.001), CT score (p < 0.001). The multivariate model, the vaccination variables, and linear trends resulted in p = 0.671 and quadratic trends p = 0.723, whilst the accumulated fluid balance is p < 0.001. Although the study has limitations, the promising results encourage more research on this different therapeutic approach, since in our research it decreases mortality.

Is Primary Bone Marrow Edema of the Knee Associated with Thyroid Disorders? A Retrospective Clinical Study.

Primary bone marrow edema (BME) of the knee is still an elusive condition. This retrospective study was undertaken to gain insight into its characteristic features. The records of 48 patients with primary BME of the knee diagnosed by magnetic resonance imaging were reviewed. Demographic data, medical history, current medications, pain type, smoking and drinking habits, allergies, occupation, sports practiced, environmental factors, and life events predating symptom onset were examined. Data analysis demonstrated that 56.3% of patients had experienced a stressful event before BME pain onset and that 50% suffered from thyroid disorders. Standard conservative treatment resulted in pain resolution irrespective of the use of anti-inflammatories. However, most patients reported new persistent symptoms: dysesthesia/hypoesthesia on palpation in the skin area overlying the previous edema and a reduced ipsilateral patellar reflex. To our knowledge, this is the first study characterizing a substantial cohort of patients with BME. We found that middle-aged, sedentary, and slightly overweight women smokers are the typical patients with primary BME of the knee. The appearance and persistence of cutaneous dysesthesia/hypoesthesia at the site of the earlier lesion and ipsilateral patellar hyporeflexia implicate an autonomous nervous system dysfunction in BME pathogenesis and warrant further investigation.

Dermatomyositis following SARS-CoV- 2 2 vaccination

Purpose: To report a case of a 51-year- old male who developed dermatomyositis following the second dose of coronavirus disease (COVID-19) vaccine. Method(s): Case report Result: Case: We report a case of 51-year- old male who developed erythematous maculopapular rash on the upper anterior chest and upper back along with symmetric proximal muscle weakness two months after receiving his second dose of CoronaVac vaccine. His symptoms were followed by edema in the periorbital area which later involved the upper and lower extremities. He had dysphagia and weight loss. He had no known family history of autoimmune diseases. Physical examination revealed macular erythema over the lower anterior neck and upper back. Heliotrope rash and hyperkeratotic pink scaly papules on bilateral lateral second digits (mechanic's hands) were seen. Symmetric proximal muscle weakness in the upper and lower extremities was objectified. Blood tests showed elevated muscle enzymes (total CK: 3899 U/L, CK MB mass: 15.4 ng/mL, LDH: 683, AST: 232 U/L, ALT: 66 IU/L) elevated ESR (36) and normal CRP. Anti Jo 1 and anti U1 RNP were negative. Work up for systemic infection, thyroid function and malignancy were unremarkable. Diagnosis: Diagnosis of dermatomyositis was made based on clinical history and physical exam findings of symmetric proximal weakness, presence of heliotrope rash, V sign and shawl sign. Laboratory tests revealed elevated total CK, CK MB mass, LDH, AST, ALT and ESR consistent with an inflammatory myositis. Intervention(s): Hydrocortisone 1 mg/kg/day was started. Azathioprine was commenced on the 3rd hospital day. Ethical consideration: Informed consent for both written and photographic content was secured and patient confidentiality was observed. Conclusion(s): This case highlights the possible association between COVID 19 vaccine and this rare autoimmune disease. We hypothesize that among patients with genetic predisposition, the possibility of vaccines triggering and unmasking an autoimmune event is possible. (Figure Presented).

Dermatomyositis: severe acute respiratory syndrome coronavirus 2, an initiator or a trigger?

Dermatomyositis is an immune-mediated inflammatory myopathy. In adults, the common triggering factors for its onset include viral infections, malignancy, and drugs. The clinical manifestation of these group of disorders may be cutaneous, neurological, pulmonary, or a combination of all. The cutaneous manifestations are helpful in the early clinical diagnosis. The detection of myositis-specific autoantibodies serves as specific biomarkers for the diagnosis and helps in predicting the prognosis. We are presenting two cases of dermatomyositis, temporally related to the severe acute respiratory syndrome coronavirus 2 infection and vaccination.

It's not the shunt: an atypical cause of fever in an infant with hydrocephalus

Case Report:We present a 5-year-old male with two days of fever, cough, vomiting, and loose stools. His history is significant for premature birth (35 weeks gestational age) and shunted hydrocephalus. A ventriculoperitoneal (VP) shunt was placed 6 days prior to presentation. Parental report included episodes of post-tussive, nonbloody, non-bilious emesis, poor oral intake, tachypnea, and increased work of breathing. Physical examination demonstrated a dehydrated infant with sunken fontanelles. He had no notable rash, no lymphadenopathy, and clear conjunctiva. His VP shunt site appeared normal without swelling or erythema. Initial evaluation showed elevated inflammatory markers -ESR 51 and CRP 12.32 mg/dL. A viral respiratory PCR panel returned positive for coronavirus (not SARS-CoV-2). A head CT scan and shunt radiography series showed no abnormalities with his shunt. The following morning, Radiology reported an incidental retropharyngeal fluid collection on a re-read of the patient's initial CT scan. A neck CT was obtained and demonstrated a fluid pocket with secondary mass effect in addition to bilateral cervical lymphadenopathy. Screening blood cultures were negative. The patient remained febrile (tmax 103.6F) and developed a transaminitis (ALT 264.9, AST 654), elevated fibrinogen 476, elevated INR 1.4, and low albumin 2.1. Abdominal ultrasound showed a normal the liver and biliary tract. His transaminitis resolved without treatment. The next day, the patient developed lip erythema and conjunctival injection. An echocardiogram showed a dilated right coronary artery (z-score of 3.59) and his inflammatory markers (ESR 26, CRP 9.63) remained elevated. Treatment was initiated with IVIG and moderate-dose aspirin. The patient defervesced, and he remained afebrile for over 48 hours prior to discharge. A repeat echocardiogram 2 days later showed a slight reduction in coronary artery dilatation (z-score 3.39). Hewas discharged on lowdose aspirin, and followed up with cardiology as an outpatient. Kawasaki's Disease (KD) is most common in children from ages 1 to 4 years and is classically characterized by persistent fever with a constellation of symptoms including limbal sparing conjunctivitis, cervical lymphadenopathy, polymorphous rash, strawberry tongue, oral changes, and extremity changes. Our patient presented at a younger age with a concurrent diagnosis of coronavirus upper respiratory tract infection. His atypical hospital course and incidental finding of retropharyngeal edema and transaminitis increased the clinical suspicion for KD. His symptoms rapidly improved after administration of IVIG. Younger patients are at an increased risk for severe complications of KD including coronary aneurysm. KD has been shown in the literature to have an association with coronavirus infection as well as presentation with retropharyngeal edema. Clinicians should consider KD in their differential even if patients do not meet all criteria for diagnosis on initial presentation. Copyright © 2023 Southern Society for Clinical Investigation.

An unusual presentation of malignant Invasive Mucinous Adenocarcinoma of Lung mimicking Pulmonary Renal syndrome

Background: A 54-year- old male presented to our centre with a chronic non-productive cough and breathlessness. Recent history of COVID treated and resolved few months back. He had a history of brain surgery performed five years back but details not known. Physical examination revealed no oedema and bilateral coarse creps with bronchiolar breathing. Laboratory findings indicated neutrophilic leucocytosis, elevated inflammatory markers, with elevated troponin I and D dimers. Urine analysis suggested microscopic haematuria with sediments. While 24 hour quantification revealed sub nephrotic proteinuria. As auto immune workup and vasculitis profile was negative and patient has not improved in spite of standard of therapy hence we went ahead with CT-Chest indicating ground-glass opacities in bilateral lung parenchyma and prominent interlobular/intralobular septal thickening. Then Bronchoscopy done which revealed the blood-stained secretions in the main stem bronchi and diffuse alveolar haemorrhage in bilateral bronchial segments indicating an inflammatory study, while tuberculosis diagnostic panel and infective bio fire panel in BAL was negative. Meanwhile, his repeat BAL culture suggested Carbapenem resistant Acinetobacter baumannii complex infection. As the patient did not respond to the standard of care for vasculitis. Probability considered was a small vessel vasculitis (namely Granulomatous polyangiitis) was considered due to lung manifestation involving upper respiratory tract with epistaxis, neutrophilic leucocytosis, elevated acute reactive protein, and renal manifestation including microscopic haematuria and proteinuria. However he responded poorly to conventional standard of treatment including pulse steroids and IVIG. Hence after MDT discussion we proceeded with lung biopsy which showed linear cores of lung tissue infiltrated by a malignant neoplasm and acinar pattern suggesting Invasive mucinous adenocarcinoma. Hence we went ahead with the biopsy diagnosis for the treatment plan. As he was to be started on chemotherapy, but he suddenly collapsed and went into hypotension, bradycardia, and cardiac arrest. In spite of high supports and post 4 cycles of CPR, was unable to revive and sadly succumbed to his illness. Discussion(s): In this rare case, the original diagnosis pointed to the pulmonary-renal syndrome, an autoimmune disease characterized by diffuse pulmonary haemorrhage and glomerulonephritis. However, negative autoimmune antibodies and vasculitis profile along with lung biopsy results indicated an unusual case of malignant lung adenocarcinoma presented with pulmonary renal syndrome. Conclusion(s): In cases suggesting pulmonary-renal syndromes, if autoimmune work up is negative and response is suboptimal relook the diagnosis.

A paralysis poser: a growing COVID concern

Purpose of Study: Report a rare case of onset of seronegative, juvenile dermatomyositis likely potentiated by Covid-19 infection Methods Used: Case analysis and literature research Summary of Results: A 7 year-old previously healthy male presented with 3 weeks of progressive, bilateral upper and lower extremity weakness, difficulty swallowing, voice changes, periorbital edema, and rash. Recent history was notable for diagnoses of COVID-19 one month prior to presentation and streptococcal pharyngitis 2 months prior to presentation. Notably, there is a family history of systemic lupus erythematosus. On examination, the patient demonstrated bilateral periorbital swelling with purple discoloration of the upper eyelids, a violaceous, pruritic, macular rash on his upper extremities and on his abdomen. Musculoskeletal exam was significant for severe axial (strength 2/5) and proximal (strength 3/5) muscleweakness with notable inability to sit unsupported or maintain head control. His neurologic exam was nonfocal;however, diffuse hyporeflexia in both upper and lower extremities were elicited. Initial screening labs were notable for mild transaminitis;positive ANA (1:80 in speckled pattern), negative ANCA, negative dsDNA/Anti- Sm, elevated aldolase of 10.3, CK 464, and LDH 665;normal thyroid studies and normal inflammatory markers. MRI with and without contrast of the spine indicated diffuse myositis of all muscle groups. Due to concern for autoimmune mediated myositis, Rheumatology was involved early in the patient's course. Empiric treatment was initiated early in the patient's presentation with IVIG, steroids, methotrexate, and plaquenil leading to gradual improvement in symptoms. Subsequent muscle biopsy was consistent with juvenile dermatomyositis (JDM). Conclusion(s): JDM is rare, occurring in 1 to 15 per million children. It classically presents with proximal myopathy and dermatologic findings of Gattron's papules, a heliotrope and malar rash. Its pathophysiology is not yet well defined but is thought to be a humoral mediated autoimmune disease. Muscle biopsies characteristically show perifascicular and perivascular infiltration. Early diagnosis and treatment with steroids, immune modulators, and physical therapy is critical to limit muscle atrophy. Viral infections are known triggers of rheumatologic diseases broadly;however, the more pronounced type 1 interferon response associated with COVID-19, which is known to be a driving pathway of JDM, may be a risk factor for severe, recalcitrant disease. Future research is needed to better identify involved pathophysiology and target future treatment efforts. Additionally, more education and case reports could focus on dermatologic presentations of individuals with pigmented skin. Copyright © 2023 Southern Society for Clinical Investigation.

Prolonged fever and inflammation in a young child in the midst of the pandemic - it's not always MIS-C

Case Report: Prolonged fever in children is a symptom that is seen in many different diseases, infections, malignancies, and autoimmune conditions. This can, at times, make the correct diagnosis challenging. A previously healthy 10-year-old male was transferred to our institution with one week history of fever, fatigue, abdominal pain, and vomiting. Laboratory studies demonstrated pancytopenia, transaminitis, electrolyte abnormalities, elevated pro-inflammatory markers & D-Dimer, and hypoalbuminemia. COVID-19 IgG was reactive. Due to the severity in presentation the patient was transferred to the ICU with a presumptive diagnosis of MIS-C. Hewas started on IVIG as well as a five-day course of high-dose methylprednisolone per protocol. Aspirin was added, but later discontinued, due to worsening thrombocytopenia. CT imaging with contrast showed small bilateral pleural effusions & periportal edema, mild splenomegaly, and echocardiogram showed diffuse dilation of the left main and left anterior descending arteries. Given the laboratory findings the differential diagnosis was expanded, Ehrlichia caffeensis serology was sent and empiric Doxycycline started. EBV Nuclear Antigen IgG antibody and EBV Viral Capsid Antigen IgM Antibody resulted as positive suggesting recent or reactivated infection. Respiratory viral PCR with COVID-19, Cytomegalovirus and Parvovirus PCR were negative. Despite initial treatment, the patient continued to have persistent fever, severe pancytopenia, and high ferritin up to 24 426 ng/mL, raising suspicion for Haemophagocytic Lymphohistiocytosis (HLH). Soluble interleukin-2 level was elevated & his presentation was then considered to be more consistent with HLH given that he met 6/8 criteria. Screening for primary HLH including CD107a, perforin and granzyme B, SAP, and XIAP resulted in the latter three being normal but CD107a was abnormal. Next generation sequencing for primary criteria was negative. E. Chaffeensis resulted positive: IgM 1:80, IgG 1:256. MIS-C and HLH have overlapping features but differ in some clinical manifestations. Timely recognition and management is paramount as the management differs. This case illustrates the importance of performing a broad search for potential causes, allowing for appropriate and timely treatment. COVID-19 serology alone should not be the basis for diagnosis of MIS-C in a patient with fever and inflammation. This is important as SARS-CoV2 becomes endemic. Infections such as EBV and Ehrlichiosis should be on the differential particularly in endemic areas and during seasons of higher prevalence for the latter, as these have been well documented to cause HLH.

Eosinophilic Oesophagitis in Children: A Single Uk Tertiary Centre Experience

The incidence of Eosinophilic Oesophagitis (EoE) is increasing worldwide in the paediatric population. Management of these children is complex, and includes elimination diet (2/4/6 food), steroids etc. It is recommended to perform endoscopies between each reintroduction to assess disease activity. In our centre dietary exclusion is the standard practice. Since 2019 we follow a step-up approach with regards to elimination diet starting with 2 food exclusion diet (FED) and building up as required. Food is reintroduced gradually with significant dietetic support and proactive monitoring including endoscopy. Objectives We looked at the outcomes of children with EoE referred to Maidstone and Tunbridge Wells NHS Trust from Kent and East Sussex. Methods Retrospective review of case notes of paediatric patients diagnosed with EoE between January 2015 and December 2020. Data collected included symptoms, endoscopy findings and histology at diagnosis and compared the same after dietary intervention. Results 21 patients were diagnosed with EoE between January 2015 and December 2020 between 5-16 yrs Median age at diagnosis 11years. Frequently seen in boys (65%). Dysphagia was the predominant symptom (76%) followed by vomiting (60%), abdominal pain (50%), and choking (20%). Features of EoE were seen during endoscopy in 71% and oesophagus looked endoscopically normal in 29% of patients. Diagnosis was made on eosinophil count as per ESPGHAN guidance. The frequency and timing of repeat endoscopies following dietary intervention varied due to a multitude of factors including COVID-19 restrictions (between 4-9 months median 4 months). Histological remission (Eosinophils <15 pHPF) was achieved in 15/21 (70%) of patients. 7/10 children on 2FED, 3/3 patients on 4FED and 5/5 children on 6FED achieved histological resolution. The 6FED group took significantly longer to identify the causative food, establish long term dietary management and required more endoscopies. Food was reintroduced gradually on an individual basis with the aim of introducing back all food groups. 13/15 continue to be on milk free diet, 5/15 remain on milk and wheat free diet, 1/15 on soya and egg free diet and the other patient remains on 4FED (parental choice). 2 patients have started steroids due to on-going symptoms findings on surveillance endoscopy and histological following re-introduction. Summary and Conclusion Dysphagia was the predominant symptom in our cohort of patients. Furrowing and oedema was the major finding during endoscopy. With dietary exclusion endoscopic resolution was seen in 62% and histological resolution seen in 70% of patients at first surveillance endoscopy. Re-introduction continues to remains a major challenge and we have not been able to introduce all the food groups in any of our patients due to either symptoms or recurrence on endoscopy/histology.

Kawasaki-like multisystem inflammatory syndrome in an adult filipino with covid-19 infection: a case report

Objectives: Several case series have been identified describing adult patients with a secondary Multisystem Inflammatory Syndrome (MIS) after a recent COVID-19 infection, presenting with features similar to Kawasaki Disease (KD). This paper aims to describe the first case of Kawasaki-like presentation in an adult Filipino with COVID-19 infection. Method(s): A case of Kawasaki-like presentation in an adult Filipino with COVID-19 infection was reviewed in a tertiary hospital. Result(s): This is a case of a 38-year- old Filipino woman who presented with fever, malaise, dry cough, sore throat, diarrhea and rashes. On examination, she had classic features of KD: non-exudative conjunctivitis, cracked lips, edema of the hands and feet, palmar erythema, diffuse rash, and cervical lymphadenopathy. Laboratory results showed anemia, leukocytosis with neutrophilia, hyponatremia, hypokalemia, transaminitis, hypoalbuminemia, and elevated inflammatory markers. COVID-19 PCR test was negative but serologic studies showed positivity for IgM and IgG, suggesting a recent infection. Treatment included methylprednisolone pulse therapy, intravenous immunoglobulin (IVIG) and anticoagulation, which resulted in rapid clinical improvement. Conclusion(s): As the knowledge of COVID-19 and its associated clinical features continually evolves, it is imperative to be aware of the possibility of KD as a delayed post-viral multisystem inflammatory response in adults that may warrant prompt treatment.

All in the Marrow - a Case of Primary Bone Marrow Oedema

Introduction/Background: Primary bone marrow oedema syndrome is an elusive and less well-defined entity. Whether Rheumatologists should consider it as a stand alone diagnosis, is debatable. It possibly would be best described as an MRI feature which could be a finding in a number of diseases which would include the initial phases of Osteonecrosis of the bone, Rheumatoid Arthritis, Spondyloarthritis, Enthesitis related, Post traumatic, OA, Infections and Cancers. The treatment options become constricted due to the paucity of evidence. Rheumatologists need to consider this as an area of unmet need with development of consensus classification criteria and treatment approaches. Description/Method: 27-year-old male, Height 174 cms Weight 90 Kgs BMI 29 Kg/m2, became symptomatic in Jan 2022 with complains of pain in the both hip joints & groin regions, pain became excruciating and he became bed-bound, with early morning stiffness lasting approximately 45 mins.

However, when he had no symptomatic relief he was administered Inj Infliximab on 12 May 2022 and a second dose on 9 June 2022. He had excellent pain relief after the 1st dose, however after 10 days of the administration, he again began experiencing pain especially after walking. He also had pain in the knees on this occasion. He was also administered Inj Zoledronic 4mg on 23 May 2022. He is at present not requiring any NSAIDs over the last 1 month. Discussion/Results: The patient having presented with excruciating and debilitating pain was worked up and evaluation revealed features of bone marrow oedema on MRI which was corroborated with bone scan and PET CT imaging. The acute phase reactant CRP was also significantly elevated. The patient also gave history of early morning stiffness lasting approximately 45 mins. Hence an underlying Inflammatory process such as Spondyloarthritis(Peripheral) with enthesitis was considered. The confounding factors were the pain which worsened on mobilization, HLA B27 negative status, Rheumatoid Factor and ACCP negative status and past history of having received IV Corticosteroids for COVID infection in August 2020. In view of the debilitating pain and aworking diagnosis of Spondyloarthritis, hewas started onNSAIDs alongwith rest, initially, followed by conventional synthetic disease modifying agents in Rheumatic disease followed by biologic synthetic diseasemodifying agent - Inj Infliximab. The thought process was to avoid prolonged NSAID use to prevent the associated side effects. However, since Avascular Necrosis of the Femoral head is a very likely possibility, the patient is planned to be kept under close follow up. Key learning points/Conclusion: Collaborative efforts between the Departments of Nuclear Medicine, Radiology, Orthopaedics and Rheumatology are crucial in the early detection and approach to cases of Bone Marrow oedema. Avascular necrosis of head of Femur is a far more common entity and must be kept in ind even when a diagnosis of Bone Marrow oedema syndrome is being entertained. Diagnosis of Bone Marrow oedema syndrome must be entertained only as a diagnosis of exclusion. Continued follow up and regular imaging must be pursued rigorously in patients diagnosed with Bone Marrow oedema syndromes. There is a requirement to document acute phase reactants such as CRP and ESR in patients diagnosed with Avascular necrosis of bone as this data could help us differentiate AVN from Primary Bone marrow oedema in the early stages.

More Than Meets the Eye: Orbital Swelling in an Adolescent with Sickle Cell Disease

Periorbital swelling is a clinical presentation with a broad differential and potentially deleterious consequence. Causes range from benign, including allergic reaction, to vision-and life-threatening, including orbital cellulitis and orbital infarction. The recent climate of SARS-CoV-2 has further complicated this differential, as the virus poses broad clinical presentations with new manifestations reported frequently. Rapid identification of the underlying etiology is crucial, as treatment approaches diverge greatly. Here, we report the case of an African American adolescent male with a history of homozygous sickle cell anemia presenting to an inner city hospital with bilateral periorbital swelling amid the coronavirus pandemic. Differentials including orbital cellulitis, COVID-MIS-C, orbital inflammatory syndrome, Hoagland sign, and orbital infarction secondary to sickle cell crisis are contrasted. We contrast our case with 12 case reports of orbital infarction in the setting of sickle cell crisis within the past 10 years, highlighting how these presentations, along with commonly reported findings of orbital infarction, compare with our patient.

COVID-19 associated Mucormycosis (CAM): Implications for perioperative physicians - A narrative review

Mucormycosis once considered a rare disease with an incidence of 0.005 to 1.7 per million, has become one of the greatest menaces during the coronavirus disease (COVID-19) pandemic. India alone has contributed to nearly 70% of the global caseload of COVID-associated mucormycosis (CAM) and it had even been declared as a notifiable disease. Second wave of COVID-19 pandemic saw a steep rise in the incidence of mucormycosis and these patients have been presenting to anesthesiologists for various surgical procedures due to its primary or secondary sequelae. Rhino-orbito-cerebral mucormycosis (ROCM) is the commonest manifestation and is caused by Rhizopus arrhizus. Injudicious use of corticosteroids in vulnerable patients could have been a major contributing factor to the sudden rise in ROCM during the pandemic. Concerns related to anesthetic management include COVID-19 infection and post COVID sequalae, common presence of uncontrolled diabetes mellitus, possibility of difficult mask-ventilation and/or intubation, various drug therapy-associated adverse effects, and interaction of these drugs with anesthetic agents. Thorough preoperative optimization, multidisciplinary involvement, perioperative care, and vigilance go a long way in improving overall outcomes in these patients.

Protein losing enteropathy (PLE) secondary to norovirus infection in a 4 year old patient

Case Report: Protein losing enteropathy (PLE) occurs when proteins leak from the gastrointestinal (GI) system more rapidly than they are produced. Inflammation of the GI tract facilitates increased membrane permeability of gastric mucosa, leading to excess protein leakage. 1 PLE in children has been associated with CMV, rotavirus, COVID-19, HIV, C. difficile, and autoimmune diseases like Crohn's Disease. 2-6 Norovirus is a known cause of PLE in immunocompromised pediatric patients. 7-8 However, to our knowledge, there are no case reports about PLE precipitated by norovirus in immunocompetent pediatric patients. The purpose of this case report is to present a case of PLE precipitated by a norovirus infection in a 4- year-old previously healthy child. While the above gastrointestinal viruses have been proposed as precipitators for this disease, PLE precipitated by norovirus infection has not been well described. This case also highlights the importance of early diagnosis and management to avoid complications. Method(s): Our patient initially presented with two days of abdominal pain, diarrhea, emesis, reduced urine output, and swelling of the lower extremities. He was exposed to several sick family members-his sister had upper respiratory symptoms and his grandmother had gastrointestinal symptoms. Physical exam was notable for diminished breath sounds in the right lower lobe, abdominal distension with diffuse tenderness and dullness to percussion, significant scrotal and penile edema, and bilateral lower extremity pitting edema. Laboratory results revealed leukocytosis, hypoalbuminemia, hyponatremia, elevated aspartate aminotransferase (AST), and elevated serum alpha-1-antitrypsin, as well as low Immunoglobulins G and M. CD3 and CD4 levels were low reflecting cellular immune dysregulation seen in patients with PLE. IgA and Tissue Transglutaminase (TTF) were within normal limits. Ebstein Barr Virus and cytomegalovirus IgM antibodies were negative. COVID IgG was negative as well. His Polymerase chain reaction (PCR) gastrointestinal panel was positive for norovirus. A chest X-ray showed a large right pleural effusion. Abdominal CT revealed large ascites slightly more predominant in the upper abdomen, mesenteric lymphadenitis, and bilateral pleural effusions. Echocardiogram showed small anterior and apical pericardial effusions. Result(s): Based on the patient's elevated serum alpha-1 antitrypsin levels, hypoalbuminemia, low levels of immunoglobulins and lymphocytes, and clinical manifestations of ascites, bilateral pleural effusions, pericardial effusion, and dependent edema, along with a positive PCR for norovirus, the diagnosis of PLE secondary to Norovirus was made. Conclusion(s): This case demonstrates the importance of recognizing viruses like Norovirus as potential causes of PLE to avoid a delay in diagnosis and initiation of therapy, and to avoid unnecessary additional testing.
