Practice Changes in Checkpoint Inhibitor-Induced Immune-Related Adverse Event Management at a Tertiary Care Center. Cancers (Basel) 2024; 16:369. [PMID: 38254858 PMCID: PMC10814014 DOI: 10.3390/cancers16020369] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2023] [Revised: 01/08/2024] [Accepted: 01/12/2024] [Indexed: 01/24/2024] Open
Abstract
Understanding of immune-related adverse events (irAEs) has evolved rapidly, and management guidelines are continually updated. We explored temporal changes in checkpoint inhibitor-induced irAE management at a tertiary cancer care center to identify areas for improvement. We conducted a single-center retrospective study of patients who developed a gastrointestinal, pulmonary, renal, or cardiac irAE between July and 1 October in 2019 or 2021. We collected patient demographic and clinical information up to 1 year after toxicity. Endoscopic evaluation and specialty follow-up after discharge for patients with gastrointestinal irAEs declined between the 2019 and 2021 periods. Symptom duration and steroid taper attempts also declined. For pulmonary irAEs, rates of specialty consultation, hospital admission and readmission, and mortality improved in 2021 compared with 2019. Follow-up rates after hospital discharge were consistently low (<50%) in both periods. For cardiac irAEs, consultation with a cardiologist was frequent and prompt in both periods. Outpatient treatment and earlier specialty consultation improved outcomes with gastrointestinal irAEs. Our study exploring irAE practice changes over time identified areas to improve management; specifically, timely specialty consultation was associated with better outcomes for gastrointestinal irAEs. These findings can help improve the quality of management algorithms at our institution and may inform policies in other institutions.

Third-Degree Atrioventricular Block Secondary to Lyme Disease: A Case Report. Cureus 2023; 15:e49803. [PMID: 38161534 PMCID: PMC10757855 DOI: 10.7759/cureus.49803] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 12/01/2023] [Indexed: 01/03/2024] Open
Abstract
Lyme carditis is a disseminated infection caused by the bite of an Ixodes tick with the transfer of Borrelia burgdorferi. It is characterized by flu-like symptoms, syncope, palpitations, and at times, erythema migrans. It is a rare systemic complication of Lyme disease that occurs when the initial infection is not promptly and completely treated. It is usually seen in patients who spend time outdoors and are thus more likely to get bitten by a tick, though anyone could be affected. This manuscript reports a case of Lyme carditis in a 26-year-old Caucasian male who suffered from flu-like symptoms, syncope, erythema migrans, and third-degree atrioventricular block after a known tick bite. The patient recovered with temporary pacing, doxycycline, and ceftriaxone. Having clinical suspicion of Lyme disease allows for early diagnosis and treatment, thus preventing more serious and systemic complications.

Effects of Antibodies in the Serum After the Administration of COVID Vaccines and Their Hematological and Cardiovascular Complications. Cureus 2023; 15:e47984. [PMID: 38034236 PMCID: PMC10686317 DOI: 10.7759/cureus.47984] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Accepted: 10/30/2023] [Indexed: 12/02/2023] Open
Abstract
The outbreak of COVID-19 was seen first in Wuhan, China, on December 31, 2019. Following this, the virus has emerged, mutated, and spread to all parts of the world, taking many lives. Scientists and healthcare workers all over the world have been involved in developing vaccines and drugs to prevent the deadly virus from spreading. In this review article, we focus on how the human body responds to immune responses by producing antibodies against our immune system and serum levels in different age groups. Few studies are being considered, which include data collected from adults in the UK community, health workers from Oxfordshire, studies from the UK, healthcare workers at a university healthcare center in Turkey, and lastly, non-seropositive and seronegative healthcare workers in the USA children's hospital, respectively, and their responses to the goal. In addition to focusing on this study and its results, we also discuss the role of different vaccines and their development and antibody responses in the body due to natural and post-vaccine infections that include both doses in humans. We focus mainly on immunoglobulin M (IgM) and immunoglobulin G (IgG) levels in the serum produced by plasma cells, as they are involved in the first line of defense against the disease. With the development of effective vaccines and their production, trial, and market distribution to needy people, there are certain prospects for slowing down the progression of the virus, reducing mortality, and preventing re-infection in humans. However impactful and beneficial these vaccines have proven, they also carry a certain amount of danger to the people taking them. We also discuss in this article certain infrequent hematological and cardiovascular complications of the vaccine and their effect on the population.

Abstract
BACKGROUND Lyme disease is one of the most common vector-borne illnesses in the United States. It is caused by Borrelia burgdorferi infection transmitted via the Ixodes tick. Rarely, it can progress to early disseminated Lyme disease with cardiac or neurologic manifestations, or both. CASE REPORT A 41-year-old previously healthy man presented to the emergency department (ED) by ambulance after an episode of syncope. Electrocardiogram revealed right bundle branch block with borderline first-degree atrioventricular nodal block. During his admission he was noted to have night sweats and elevated procalcitonin. Infectious workup revealed positive Borrelia enzyme-linked immunosorbent assay. Further testing revealed positive Borrelia immunoglobulin M with negative immunoglobulin G, indicating a recent infection. Why should an emergency physician be aware of this? Lyme disease should be on the differential for patients presenting with vague, flu-like symptoms in the summer months in endemic areas. Treatment of early Lyme disease with doxycycline can prevent progression to secondary Lyme, which can present as a true cardiac or neurologic emergency.

Modulators of radiation-induced cardiopulmonary toxicities for non-small cell lung cancer: Integrated cytokines, single nucleotide variants, and HBP systems imaging. Front Oncol 2022; 12:984364. [PMID: 36591530 PMCID: PMC9797663 DOI: 10.3389/fonc.2022.984364] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2022] [Accepted: 11/21/2022] [Indexed: 12/23/2022] Open
Abstract
Radiation therapy (RT)-induced cardiopulmonary toxicities remain dose-limiting toxicities for patients receiving radiation dosages to the thorax, especially for lung cancer. Means of monitoring and predicting for those receiving RT or concurrent chemoradiation therapy before treatment begins in individual patients could benefit early intervention to prevent or minimize RT-induced side effects. Another aspect of an individual's susceptibility to the adverse effects of thoracic irradiation is the immune system as reflected by phenotypic factors (patterns of cytokine expressions), genotypic factors (single nucleotide variants SNVs; formerly single nucleotide polymorphisms [SNPs]), and aspects of quantitative cellular imaging. Levels of transcription, production, and functional activity of cytokines are often influenced by SNVs that affect coding regions in the promoter or regulatory regions of cytokine genes. SNVs can also lead to changes in the expression of the inflammatory cytokines, interferons, interleukins (IL-6, IL-17) and tumor necrosis factors (TNF-α) at the protein level. RT-induced cardiopulmonary toxicities could be quantified by the uptake of 18F-fluorodeoxyglucose (FDG), however, FDG is a sensitive but not specific biomarker in differential diagnosis between inflammation/infection and tumor recurrence. FDG is suitable for initial diagnosis of predisposed tissue injuries in non-small cell lung cancer (NSCLC). 99mTc-ethylenedicysteine-glucosamine (99mTc-EC-G) was able to measure tumor DNA proliferation and myocardial ischemia via hexosamine biosynthetic pathways (HBP). Thus, 99mTc-EC-G could be an alternative to FDG in the assessment of RT doses and select patients in HBP-directed targets for optimal outcomes. This article reviewed correlative analyses of pro-inflammatory cytokines, genotype SNVs, and cellular imaging to improve the diagnosis, prognosis, monitoring, and prediction of RT-induced cardiopulmonary toxicities in NSCLC.

Abstract
INTRODUCTION Acute rheumatic fever is an autoimmune disease that develops due to streptococcal infection. The positive effect of breastfeeding on the development of the child's immune system is well documented. In this study, we aimed to investigate the effect of breast milk intake period on the development of carditis. MATERIALS AND METHODS Patients (n: 182) who were diagnosed with acute rheumatic fever between 2010 and 2019 were enrolled in the study. The patients were divided into groups according to carditis development. The demographic, socio-economic, and breastfeeding data were compared between groups. RESULTS The mean age of the patients was 10.5 ± 3.4, and 43.4 % (n: 79) of them were female. Independent predictors of the development of carditis in the first acute rheumatic fever episode were the number of children at home (OR: 1.773, CI 95%: 1.105, 2.845; p: 0.018) and breast milk intake less than 6 months (OR: 0.404, CI 95%: 0.174, 0.934; p: 0.034). Independent predictors of the development of carditis in any of the acute rheumatic fever episodes were the number of children at home (OR: 1.858, CI 95%: 1.100, 3.137; p: 0.021) and female gender (OR: 3.504, CI 95%: 1.227, 10.008; p: 0.019). The only independently predictor of the development of chorea during acute rheumatic fever was female gender (OR: 3.801, CI 95%: 1.463, 9.874; p: 0.006). CONCLUSION Although the occurrence of carditis is less common during the first acute rheumatic fever attack in patients with breast milk intake less than six months, this advantage is lost in recurrent attacks. This study showed that breast milk does not have a negative effect on acute rheumatic fever carditis.

A Comparative Analysis of COVID-19 Vaccines Based on over 580,000 Cases from the Vaccination Adverse Event Reporting System. Vaccines (Basel) 2022; 10:vaccines10030408. [PMID: 35335040 PMCID: PMC8950485 DOI: 10.3390/vaccines10030408] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2022] [Revised: 02/23/2022] [Accepted: 03/04/2022] [Indexed: 02/04/2023] Open
Abstract
Background: The COVID-19 pandemic is being battled via the largest vaccination campaign in history, with more than eight billion doses administered thus far. Therefore, discussions about potentially adverse reactions, and broader safety concerns, are critical. The U.S. Vaccination Adverse Event Reporting System (VAERS) has recorded vaccination side effects for over 30 years. About 580,000 events have been filed for COVID-19 thus far, primarily for the Johnson & Johnson (New Jersey, USA), Pfizer/BioNTech (Mainz, Germany), and Moderna (Cambridge, USA) vaccines. Methods: Using available databases, we evaluated these three vaccines in terms of the occurrence of four generally-noticed adverse reactions—namely, cerebral venous sinus thrombosis, Guillain−Barré syndrome (a severe paralytic neuropathy), myocarditis, and pericarditis. Our statistical analysis also included a calculation of odds ratios (ORs) based on total vaccination numbers, accounting for incidence rates in the general population. Results: ORs for a number of adverse events and patient groups were (largely) increased, most notably for the occurrence of cerebral venous sinus thrombosis after vaccination with the Johnson & Johnson vaccine. The overall population OR of 10 increases to 12.5 when limited to women, and further yet (to 14.4) among women below age 50 yrs. In addition, elevated risks were found (i) for Guillain−Barré syndrome (OR of 11.6) and (ii) for myocarditis/pericarditis (ORs of 5.3/4.1, respectively) among young men (<25 yrs) vaccinated with the Pfizer/BioNTech vaccine. Conclusions: Any conclusions from such a retrospective, real-world data analysis must be drawn cautiously, and should be confirmed by prospective double-blinded clinical trials. In addition, we emphasize that the adverse events reported here are not specific side effects of COVID vaccines, and the significant, well-established benefits of COVID-19 vaccination outweigh the potential complications surveyed here.

Abstract
Lyme disease caused by Borrelia burgdorferi is a multisystem disease and can lead to Lyme carditis. The most common presentation of Lyme carditis is conduction system disturbances such as atrioventricular (AV) block. A 72-year-old male with a past medical history of gastroesophageal reflux disease (GERD) and prostate cancer presented with chest tightness, lightheadedness, and presyncope. During hospitalization, he developed bradycardia with heart rates ranging between 30 and 40 beats per minute and Wenckebach heart block. Lyme serology was consistent with a recent Lyme infection. He was treated with antibiotics and was eventually discharged home without requiring pacemaker implantation.

Abstract
Secondary prophylaxis of rheumatic heart diseases is efficient in reducing disease recurrence, heart damage, and cardiac impairment. We aimed to monitor the clinical evolution of a large Brazilian cohort of rheumatic patients under prolonged secondary prophylaxis. From 1986 to 2018, a cohort of 593 patients with rheumatic fever was followed every 6 months by the Reference Center for the Control and Prevention of Rheumatic Fever and Rheumatic Cardiopathy (CPCFR), Paraná, Brazil. In this cohort, 243 (41%) patients did not present cardiac damage (group I), while 350 (59%) were diagnosed with rheumatic heart disease (RHD) (group II) using the latest case definition. Among group II, 233 and 15 patients had impairment of the mitral and aortic valves, respectively, while 102 patients had impairment of both valves. Lesions on the mitral and aortic valves presented a regression in 69.9 and 48.7% of the patients, respectively. Active patient recruitment in the reference center and early detection of oropharyngeal GAS were important factors for optimal adherence to the prophylactic treatment. Patients with disease progression were associated with noncompliance to secondary prophylaxis. No patients undergoing regular prophylaxis presented progression of the rheumatic cardiac disease. Eighteen valvular surgeries were performed, and four (0.7%) patients died. This study confirmed that tailored and active efforts invested in rheumatic heart disease secondary prevention allowed for significant clinical improvement.

Abstract
Background Lyme carditis is an uncommon manifestation of Lyme disease. This report compares Lyme carditis presentation, management, and outcomes in pediatric and adult populations. Methods Charts of pediatric and adult patients with heart block (PR interval >300 ms) and positive Lyme serologies hospitalized in Portland, Maine, between January 2010 and December 2018 were analyzed. Data on medical history, presentation, treatment, and outcomes are described. Results Ten children and 20 adults were admitted for Lyme carditis between June and October. Ninety percent were male, and 87% had no prior cardiac history. Seventeen had outpatient evaluation before admission. Of these, a minority (41%) had Lyme disease suspected in the outpatient setting, and fewer (12%) were initiated on Lyme disease treatment. The most common alternate diagnoses were viral illness and erythema multiforme. More children than adults had disseminated erythema migrans and fever. First-degree heart block was more prevalent in children, and Mobitz type 2 heart block was more prevalent in adults. Ten patients presented with syncope. Proportionately more adults needed temporary pacing. Children had shorter antibiotic durations compared with adults. Of the 30 cases, 27 had improved heart block, while 3 adults required a pacemaker at discharge. Nine children and 14 adults were discharged with a PR 200–300 ms. There was a single death in this series. Conclusions Cases tended to be younger males. Most patients had some heart block on discharge. Of patients evaluated as outpatients, Lyme disease was suspected in 41%. Improved early recognition and treatment of Lyme disease may decrease Lyme carditis.

Abstract
Acute rheumatic fever (ARF) is a non-septic complication of group A β-hemolytic streptococcal (GAS) throat infection. Since 1944, ARF diagnosis relies on the Jones criteria, which were periodically revised. The 2015 revision of Jones criteria underlines the importance of knowing the epidemiological status of its own region with updated data. This study aims to describe ARF features in a retrospective cohort retrieved over a 10-year timespan (2009–2018) and to report the annual incidence of ARF among children in the Province of Monza-Brianza, Lombardy, Italy during the same period. This is a multicentric cross-sectional/retrospective study; 70 patients (39 boys) were diagnosed with ARF. The median age at diagnosis was 8.5 years (range, 4–14.2 years). Overall, carditis represented the most reported major Jones criteria followed by arthritis and chorea (40, 27, and 20 cases, respectively). In order to calculate the annual incidence of ARF, only children resident in the Province of Monza-Brianza were included in this part of the analysis. Therefore, 47 patients aged between 5 and 14 years were identified. The median incidence during the study time was 5.7/100,000 (range, 2.8–8.3/100,000). In the Province of Monza-Brianza, we found an incidence rate of ARF among children aged 5–14 years constantly above the threshold of low-risk area as defined in the 2015 revision of Jones criteria. Therefore, the diagnosis of ARF should be based on the moderate–high-risk set of Jones criteria. However, given the burden of secondary prophylaxis, expert opinion is advisable when the diagnosis of ARF is uncertain.

Henoch Schönlein purpura (HSP) with acute rheumatic fever (ARF) is a rare entity and only few cases have been reported so far. In all previously reported cases with HSP and ARF, patients initially presented with purpuric rash, arthralgia/arthritis, or abdominal pain and later diagnosed as ARF. We report an 11-year-old girl with features of both ARF and HSP. She initially presented with arthralgia and murmur. Echocardiography showed mild to moderate mitral regurgitation. Later, the clinical course was complicated by purpuric rash and abdominal pain. She was treated conservatively with IM penicillin, acetylsalicylic acid and oral prednisolone. Our patient is the first patient with HSP and ARF who initially presented with features of ARF. A review of literature revealed a limited number of cases of HSP associated with ARF (14 cases including the present case); and that the response to treatment in cases suffering from ARF associated with HSP was good; but one should also be aware of serious cardiac complications in HSP patients which may be fatal.

Abstract
Introduction: Henoch-Schönlein purpura (HSP) is the most common vasculitis of childhood. The classic triad of HSP consists of nonthrombocytopenic purpura, arthritis/arthralgia, and gastrointestinal complaints. Pulmonary hemorrhage and cardiac involvement are rare complications of HSP. Case Report: We report the case of a 10-year-old girl with HSP complicated by both severe mitral regurgitation and pulmonary hemorrhage. Discussion: HSP is typically a self-limited illness with an excellent prognosis in children. Pulmonary hemorrhage is a rare complication that increases morbidity and mortality; it generally indicates the presence of severe vasculitis. Cardiac involvement in HSP is extremely rare and associated with a poor prognosis. Conclusion: Cardiac involvement in HSP may be more common than believed. Because of the increased morbidity and mortality associated with HSP complicated by pulmonary hemorrhage and cardiac involvement, it is important for clinicians to be aware of these potential complications.

Abstract
The persistence of acute rheumatic fever continues to be seen globally. Once thought to be eradicated in various parts of the world, the disease came back with a vengeance secondary to a lack of diligence on the part of providers. Today, the global burden of group A streptococcal infection, the culprit of the numerous sequelae manifested in acute rheumatic fever, is considerable. Although a completely preventable disease, rheumatic fever continues to exist. It is a devastating disease that involves long-term, multisystem treatment and monitoring for patients who were unsuccessful at eradicating the precipitating group A streptococcal infection. Prevention is the key to resolving the dilemma of the disease's global burden, yet the method to yield its prevention still remains unknown. Thus, meticulous attention to implementing proper treatment is the mainstay and remains a top priority.

Early-onset Lyme carditis with concurrent disseminated erythema migrans. AMERICAN JOURNAL OF CARDIOVASCULAR DISEASE 2017; 7:53-56.

Abstract
BACKGROUND Lyme disease is an infection that is estimated to affect over 300,000 people in the United States annually. Typically, it presents with erythema migrans (EM), an annular rash at the site of tick attachment, within 3 to 30 days of inoculation. Untreated patients may progress to early disseminated disease. A further complication, Lyme carditis is rare but may occur several weeks later. It commonly manifests as a variable atrioventricular (AV) conduction block, with a high-grade AV block occurring in only 1% of untreated patients. This case demonstrates an unusually early presentation of Lyme carditis with complete heart block. CASE PRESENTATION A 21-year-old male was transferred from an outside emergency department (ED) for possible pacemaker placement due to symptomatic third-degree AV block. Four days earlier the patient presented to the outside ED with fever, chills, and unrecognized EM on his right neck. He was discharged with antipyretics, but no antibiotic therapy. On the day of transfer, he returned with persistent fevers, EM now on his trunk and upper extremities, lightheadedness, and substernal chest pressure. An electrocardiogram revealed the third-degree AV block leading to transfer. Upon arrival, the patient was promptly diagnosed with Lyme carditis. Pacemaker implantation was deferred, and intravenous (IV) ceftriaxone was initiated. Within 48 hours his third-degree AV block improved to a first-degree block. By this time, his EM had also resolved. He was discharged with oral doxycycline and a 30-day event monitor, which ultimately showed persistent first-degree AV block. CONCLUSIONS This case reinforces a unique presentation of Lyme carditis. Disseminated EM and Lyme carditis may present concurrently within 2 weeks of tick attachment. Early recognition and treatment is important for preventing progression to disseminated infection. Lyme-associated AV block will reverse within 48 to 72 hours of initiating IV antibiotic therapy and will not require pacemaker implantation. Lyme carditis should be considered in patients without heart disease who present with any degree of AV block.

Abstract
Sydenham's chorea (SC) is characterised by chorea, emotional lability and hypotonia. In this study, we investigated the incidence and clinical presentation of childhood SC in Ireland (years 2006-2014). Nineteen cases were diagnosed. Five patients had rheumatic fever. An increasing trend with an incidence of 0.23/100 000 is reported. As most referral diagnoses included psychogenic illness, head injury and stroke, modern physicians may not be aware of this age old illness. A review of the manifestations and diagnosis of SC is presented.

Abstract
OBJECTIVE To investigate the type of cardiac mucosa and its relationship with age and gender of the participants and to determine the coincidence of endoscopic and pathological diagnosis of carditis as well as its etiology. METHODS The data of 70 patients with carditis (the carditis group) and 30 individuals with endoscopically normal-appearing cardiac mucosa (the control group), including their baseline characteristics and histopathological findings, were reviewed. Their Helicobacter pylori (H. pylori) status was also reviewed. RESULTS Three main types of cardiac mucosa: mucous, oxyntic and mixed types, were found in 45.0%, 40.0% and 15.0% of all the participants, respectively. The distribution of these types was related to the age of the participants but not to their gender. Moderate to severe mucosal inflammation was detected in 60.0% (18/30) of the control group. The etiologies of cardiac inflammation were H. pylori infection and gastroesophageal reflux disease (GERD). For antral H. pylori-negative participants, cardiac mucosal inflammation was correlated with esophageal mucosal inflammation (P < 0.05), while for those with antral H. pylori infection it was associated with antral mucosal inflammation (P < 0.01). CONCLUSIONS The distribution of different cardiac mucosal types was related to the participants' age. Normal-appearing cardiac mucosa under endoscopy might present with histopathologically moderate to severe cardiac inflammation. The etiologies of cardiac inflammation were H. pylori infection and GERD. Different causes of carditis may result in the different histological performance of the cardia.

Rheumatic silent carditis: echocardiographic diagnosis and prognosis of long-term follow up. Pediatr Int 2013; 55:685-9. [PMID: 23789715 DOI: 10.1111/ped.12163] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2012] [Revised: 02/17/2013] [Accepted: 06/14/2013] [Indexed: 11/29/2022]
Abstract
BACKGROUND Rheumatic fever and rheumatic heart disease continue to be an important public health problem in developing countries. Doppler echocardiography is now widely used for early detection and recurrence of clinical evident carditis (CC) and silent (subclinical) carditis (SC). The aim of this study was to determine the frequency of SC and to compare clinical and echocardiographic features of CC and SC. METHODS A total of 156 consecutive patients diagnosed with acute rheumatic fever were included in the study. The patients without clinical evidence but with echocardiographic findings of carditis were diagnosed as having SC. RESULTS Acute rheumatic fever was diagnosed in 156 patients, and 103 of these (66%) had carditis. The prevalence of SC was 28.2% among these 103 patients. Seventy-four of the patients with carditis were followed up for >1 year, and 20 of those had SC. Valvular regurgitation disappeared completely in 18.5% and improved in 45.5% of the CC patients. The recovery and improvement rates in the SC group were 15% and 30%, respectively. CONCLUSION It is suggested that Doppler echocardiography be performed in all patients with suspected acute rheumatic fever for early detection of SC. Echocardiography should be used as a diagnostic criterion in order not to miss a diagnosis of SC.

Abstract
A 41 -year old female patient was admitted with acute onset of dyspnea and chest pain. Previous history revealed asthma, chronic sinusitis and eosinophilic proctitis. Electrocardiogram showed anterior ST-segment elevations and inferior ST-segment depression. Immediate heart catheterization revealed a distally occluded left anterior descending coronary artery, the occlusion being reversible after nitroglycerine. Cardiac magnetic resonance imaging was consistent with perimyocarditis. Hypereosinophilia and IgE elevation were present and Churg-strauss syndrome was diagnosed.

Abstract
OBJECTIVE The objective was to study the profile of acute rheumatic fever (ARF) at high and low altitudes (hot and temperate areas respectively) with particular attention to the influence of these differences on the frequency or severity of carditis. METHODOLOGY Thirty eight children with initial attack of ARF, diagnosed between November 1987 and July 1995, were studied. RESULT Twenty seven were living at altitude, temperate climate (group-1) while 11 were living at low altitudes of Tihama, hot climate (group-2). Twenty two were males and 16 were females. The mean age was 9.7 years. Arthritis was the commonest feature (86.8%) and carditis (68.4%) came second. Mitral regurgitation occurred in 96.2% of those with carditis, aortic regurgitation occurred in 19.2% and tricuspid regurgitation in 7.7%. Mitral stenosis and aortic stenosis were not encountered. A comparison between group-1 and group-2 showed the frequency of carditis to be 66.7% and 72.7% respectively and the frequency of severe carditis in those affected to be 27.8% and 25% respectively. Chorea, erythema marginatum and subcutaneous nodules were uncommon. CONCLUSION The study indicates that altitude and climate may not affect the frequency nor severity of carditis.
