Acute lupus myocarditis: clinical features and outcome of an oriental case series

Symptomatic myocarditis in systemic lupus erythematosus (SLE) is uncommon. We describe the clinical characteristics, management and outcomes of 11 SLE patients without any atherosclerotic risk factors, who presented with acute lupus myocarditis (ALM). All patients were female, 46% Chinese with mean age of 27 +/- 10 years at diagnosis of SLE. ALM was one of the initial manifestations of SLE in eight (73%) patients. The median duration from onset ALM to initiation of treatment was two weeks (range: 0.3-8). All had clinical feature of left ventricle dysfunction. The most common electrocardiographic feature was nonspecific ST/T wave changes (91%). Common echocardiographic findings included segmental wall motion abnormalities (81%) and decreased left ventricular ejection fraction (81%). Median SLE disease activity index at presentation was 16 (range: 4-30). All patients received high dose corticosteroids and 64% received intravenous pulse cyclophosphamide. There were two deaths (18%) from infections. The remaining nine survivors had no recurrence of ALM nor suffer any SLE-related damage (median SLICC damage score of 0), up to a median follow-up of four years (range: 2.5-10.1). Repeat echocardiography after six months or later showed normal LVEF in eight patients (89%). Early immunosuppressive therapy in ALM, with high dose corticosteroids and pulse intravenous cyclophosphamide, results in good cardiac outcome.     

Use of high-dose intravenous immunoglobulin in systemic lupus erythematosus: report of three cases

Three patients with life-threatening manifestations of systemic lupus erythematosus (SLE), unresponsive to conventional high-dose corticosteroid and/or immunosuppressive therapy were treated with intravenous polyspecific IgG (IVIG). Following IVIG infusion, lupus encephalitis in the first patient quickly resolved and the impressive improvement of the clinical status was associated with a transient increase in C1q-binding activity. The daily infusion of IgG had to be suspended after three days in the second patient with encephalitis and nephritis, because the renal function rapidly deteriorated; subsequently, six plasma exchanges led to an almost complete recovery. Finally, leukocyte and platelet counts increased and remained within normal range following IgG therapy in the third patient having SLE-associated leuko- and thrombocytopenia. In all three patients a decrease in anti-DNA antibody levels and an increase in total complement hemolytic activity were detected after therapy.     

Marked Improvement of Severe Cardiac Dysfunction After One Course of Intravenous Immunoglobulin in a Patient with Systemic Lupus Erythematosus

Intravenous immunoglobulin (IVIg) is currently used with much enthusiasm for the treatment of many autoimmune diseases, including systemic lupus erythematosus (SLE). Among its various indications, IVIg has also been found to be beneficial in myocarditis, whether or not it is associated with an autoimmune disease (e.g. Kawasaki’s disease). We report a 59-year-old SLE patient who, while being treated with steroids, developed severe cardiac dysfunction with a left ventricular ejection fraction of 20%. Coronary angiography demonstrating normal coronary arteries supported the diagnosis of myocarditis. High-dose IVIg treatment was started, followed by improved cardiac function a few days later and normalisation of the ejection fraction (50%) 1 month later. This is the second report of a beneficial effect of IVIg in myocarditis secondary to SLE. Received: 27 June 1998 / Accepted: 2 November 1998     

Utilisation hors AMM d’immunoglobulines intraveineuses dans le traitement de la myocardite lupique : à propos de deux cas et revue de la littérature

Introduction

Several case reports have reported the benefit of intravenous immunoglobulin therapy in many autoimmune diseases, including systemic lupus erythematosus.

Efficacy and safety of Etanercept, high-dose intravenous gammaglobulin and plasmapheresis combined therapy for lupus diffuse proliferative nephritis complicating pregnancy

We report one case of pregnancy-onset severe diffuse proliferative nephritis in a patient with systemic lupus erythematosus (SLE), who was successfully treated with a combination of anti-tumour necrosis factor (TNF)-alpha, plasmapheresis and high-dose intravenous gammaglobulin. No flares were observed either in clinical symptoms or in laboratory examinations during pregnancy or after delivery. Her autoantibodies except fluorescent anti-nuclear antibodies were negative. We suggest that a combination of anti-TNF-alpha, plasmapheresis and high-dose intravenous gammaglobulin may be a safe and effective therapy for pregnant patients suffering severe lupus nephritis.     

Intravenous amiodarone in the treatment of refractory life-threatening cardiac arrhythmias in the critically ill patient

Eleven critically ill patients with life-threatening cardiac arrhythmias refractory to currently approved antiarrhythmic drugs were treated with intravenous amiodarone. Two patients had acute myocarditis, five had acute myocardial infarction, two had left ventricular failure secondary to ischemic heart disease, one had Wolff-Parkinson-White syndrome, and one manifested postoperative atrial fibrillation. Eight of the patients had severe cardiac failure and five had hypotension requiring intravenous dopamine. Five patients were treated for recurrent ventricular fibrillation, two for recurrent ventricular tachycardia, and four for recurrent atrial arrhythmlas. Six patients had repeated cardioversions. The arrhythmias had lasted a mean of 88.3 hours resistant to a mean of 2.7 different intravenous antiarrhythmic drugs. The ventricular arrhythmias did not recur after commencing intravenous amiodarone, but some minor atrial arrhymias occurred for 24 hours. One patient died of intractable left ventricular failure, chronic obstructive lung disease, and respiratory arrest during treatment. The dose of amiodarone was 150 mg over 5 minutes, followed by 600 mg/24 hr for 3 to 4 days; one patient on total parenteral nutrition required intravenous amiodarone for 20 days. Hypotension, cardiac failure, and bradyarrhythmias were not induced by this treatment. Intravenous amiodarone can be used safely in critically ill patients with impaired left ventricular function to control life-threatening refractory cardiac arrhythmias.     

Juvenile-onset multifocal osteonecrosis in systemic lupus erythematosus: A case report

Rationale:Osteonecrosis (ON) is a devastating illness that leads to bone ischemia and potential joint destruction. Systemic lupus erythematosus (SLE) is a chronic, autoimmune disease, with multi-system involvement which is closely associated with occurrence of ON. Multifocal ON, with an estimated morbidity of 3% in SLE patients, is extremely rare in juvenile subjects.Patient concerns:A 13.3-year-old female SLE patient was admitted to hospital 20 months following the SLE diagnosis because of a sudden aggravation of sore knees. She suffered from double knee joint pain and her left knee joint showed typical signs of inflammation including redness, swelling, heat, and pain.Diagnoses:The SLE patient was diagnosed with multifocal ON of her knee joint based on magnetic resonance imaging findings of bone destruction and osteoproliferation at the bilateral distal femur and proximal tibia.Interventions:The patient received high-dose methylprednisolone and intravenous cyclophosphamide pulse therapies for controlling active lupus and nephritis. Oral calcitriol and dipyridamole were administered to alleviate knee pain and inhibit thrombi formation, thereby suppressing ON progress.Outcomes:Three weeks following the treatment, the swelling in patient''s left knee subsided. Her self-reporting pain score decreased from 9 to 4 and walking time increased from 45minutes to 90minutes per day. Nearly 5 weeks later, the pain in bilateral knee joints disappeared and the patient could walk without difficulties.Lessons:This patient is the youngest SLE patient who developed multifocal ON based on the reported literature. It suggests that ON can occur in young SLE patients. A combination of internal and external risk factors can promote the development of ON. The balanced approach to the application of corticosteroids and immunosuppressors in the treatment of SLE and prevention of ON is a challenging problem that deserves further exploration.     

Lupus enteritis: clinical characteristics, risk factor for relapse and association with anti-endothelial cell antibody

The study was undertaken to evaluate clinical and laboratory characteristics of patients with lupus enteritis and to investigate its association with anti-endothelial cell antibodies (AECAs). Systemic lupus erythematosus (SLE) patients who were admitted to Kangnam St. Mary's Hospital with complaints of acute abdominal pain from January 1990 to July 2006 were reviewed retrospectively. The clinical features, laboratory data and prognosis of these patients were analyzed. Among the 706 SLE patients admitted during the study period, 87 were found to admit for acute abdominal pain. Among them, 41 patients were identified with lupus enteritis. The SLE disease activity index score at admission and the mean prednisolone dose administered during the last three months prior to admission were significantly higher in patients with lupus enteritis than those with other causes (P < 0.001, P = 0.036). Serum anti-endothelial cell antibody (AECA-IgG) titer was also significantly higher in patients with lupus enteritis than those with other manifestations or healthy controls (P = 0.040, P < 0.001). Four out of 13 recurrent patients had pre-existing anti-phospholipid syndrome (APS), whereas only one out of 28 non-recurrent patients had pre-existing APS (P = 0.028). Most of the patients with lupus enteritis showed good response to high-dose intravenous steroids and there was no death directly associated with lupus enteritis.     

The heart in systemic lupus erythematosus and the changes induced in it by corticosteroid therapy: A study of 36 necropsy patients

The natural history of the cardiovascular manifestations of systemic lupus erythematosus (SLE) have been altered by corticosteroids which exert their own cardiovascular effects. This study describes clinical and necropsy observations in 36 corticosteroid-treated patients with SLE and compares them to necropsy observations in patients with SLE reported before the use of corticosteroid therapy. The 36 patients averaged 32 years of age, and 33 were women. Systemic hypertension was present in 25 (69 per cent) and left ventricular hypertrophy in 23 (64 per cent) patients. Hypertension was twice as common in the 19 patients who received this drug for more than 12 months (average 38 months) than in the 17 patients who received this drug for less than 12 months (average 6 months), and was almost five times more common among our patients than in patients with SLE in the presteroid era. Congestive cardiac failure occurred in 15 patients (43 per cent), eight times more frequent than that reported in noncorticosteroid-treated patients with SLE. Subepicardial and myocardial fat was increased in all 36 patients.Lupus carditis was similar in frequency but differed morphologically in our patients compared to those not treated with corticosteroids. Libman-Sacks-type endocardial lesions, present in 18 (50 per cent) of our patients, were smaller, fewer in number, univalvular rather than multivalvular, and mainly left-sided. Most verrucae were either partly or completely healed, and some were calcified. Pericarditis, present in 19 (53 per cent) patients, was predominantly of the fibrous type. Myocarditis was present in three patients, each of whom also had endocarditis and pericarditis. The lumen of at least one of the three major coronary arteries was narrowed more than 50 per cent by atherosclerotic plaques in 42 per cent of the 18 patients who received corticosteroids for more than 1 year, but in none of the 17 patients who received corticosteroids for less than 1 year. Four of the eight patients with narrowed coronary arteries had myocardial infarcts.Although vital to the management of SLE, corticosteroids have an over-all deleterious effect on the heart. Systemic hypertension and left ventricular hypertrophy appear or, when present, worsen; congestive cardiac failure increases; epicardial and myocardial fat increases, and coronary atherosclerosis appears to be accelerated.     

Cyclophosphamide pulse therapy in optic neuritis due to systemic lupus erythematosus: an open trial.

OBJECTIVE: To evaluate the efficacy of intravenous cyclophosphamide pulse therapy in patients with optic neuritis associated with systemic lupus erythematosus (SLE). PATIENTS AND METHODS: Ten consecutive patients with optic neuritis due to SLE whose condition was refractory to corticosteroids and oral immunosuppressants were treated with intravenous cyclophosphamide (0.5 to 1.0 g/m2) monthly for 6 months. RESULTS: All patients had bilateral eye involvement. One eye was legally blind, and 13 eyes could see only hand movements or count fingers. Six patients had evidence of the secondary antiphospholipid antibody syndrome. Complete recovery in visual acuity occurred in 10 eyes (50%), and a partial response occurred in six eyes (30%); four eyes (20%) had no response. Complete response in the field tests occurred in eight eyes (40%), with a partial response in nine eyes (45%); no improvement occurred in three eyes (15%). CONCLUSIONS: Intravenous cyclophosphamide pulse therapy seems to be an effective treatment for optic neuritis refractory to corticosteroids, oral immunosuppressants, or both. A randomized controlled trial will be necessary to confirm our results.     

Refractory immune thrombocytopenia in systemic lupus erythematosus: response to mycophenolate mofetil

Immune thrombocytopenia (IT) is a common manifestation of systemic lupus erythematosus (SLE). Although severe IT (<20 x 10(9)/L) occurs in about 5-10% of patients, usually in the context of active disease, the absence of randomized controlled trials has not allowed the development of evidence-based guidelines for managing this condition. Conventionally, high-dose glucocorticoids are considered first-line therapy. Adjunctive medical and surgical treatments for patients with an absent or partial response to glucocorticoids have met with varying degrees of success. We describe an SLE patient with IT refractory to high-dose corticosteroids, pulse methylprednisolone and intravenous immunoglobulin therapy, whose platelet counts normalized during therapy with mycophenolate mofetil (MMF). Pending further controlled studies to confirm this observation, we suggest that MMF may be considered as a therapeutic option in the treatment of glucocorticoid-refractory immune thrombocytopenia in SLE.     

Clinical outcomes of acute myocarditis in childhood

OBJECTIVE: To describe clinical outcomes of a paediatric population with histologically confirmed lymphocytic myocarditis. DESIGN: A retrospective review between November 1984 and February 1998. SETTING: A major paediatric tertiary care hospital. PATIENTS: 36 patients with histologically confirmed lymphocytic myocarditis. MAIN OUTCOME MEASURES: Survival, cardiac transplantation, recovery of ventricular function, and persistence of dysrhythmias. RESULTS: Freedom from death or cardiac transplantation was 86% at one month and 79% after two years. Five deaths occurred within 72 hours of admission, and one late death at 1.9 years. Extracorporeal membrane oxygenation support was used in four patients, and three patients underwent heart replacement. 34 patients were treated with intravenous corticosteroids. In the survivor/non-cardiac transplantation group (n = 29), the median follow up was 19 months (range 1.2-131.6 months), and the median period for recovery of a left ventricular ejection fraction to > 55% was 2.8 months (range 0-28 months). The mean (SD) final left ventricular ejection and shortening fractions were 66 (9)% and 34 (8)%, respectively. Two patients had residual ventricular dysfunction. No patient required antiarrhythmic treatment. All survivors reported no cardiac symptoms or restrictions in physical activity. CONCLUSIONS: Our experience documents good outcomes in paediatric patients presenting with acute heart failure secondary to acute lymphocytic myocarditis treated with immunosuppression. Excellent survival and recovery of ventricular function, with the absence of significant arrhythmias, continued cardiac medications, or restrictions in physical activity were the normal outcomes.     

Possible association between anti-Ro antibodies and myocarditis or cardiac conduction defects in adults with systemic lupus erythematosus.

In view of the association of congenital heart block with maternal antibody to cellular antigen Ro (SSA), and one report linking anti-Ro with myocarditis in a patient with myositis an association between anti-Ro antibodies and cardiac disease was sought in adults with systemic lupus erythematosus (SLE). Among 67 patients with SLE, of whom 36 were anti-Ro positive, a significantly higher prevalence of myocarditis and conduction defects was found in the anti-Ro positive group (eight of 36) than in those who were anti-Ro negative (one of 31) and healthy controls (one of 50). Of the 36 anti-Ro positive patients with SLE, three had symptoms diagnostic of myocarditis, and an electrocardiogram showed first degree atrioventricular block and unifascicular block in three cases (including one with myocarditis), right bundle branch block alone (two cases), and first degree atrioventricular block alone (one case). Complete atrioventricular block was not seen. In the anti-Ro negative group there was no myocarditis and only one case of conduction defect (right bundle branch block). Among healthy controls only one of 50 had first degree atrioventricular block. It is concluded that myocarditis and conduction defects are reasonably common in adults with SLE and are associated with anti-Ro antibodies.     

Churg-Strauss syndrome presenting with acute myocarditis and cardiogenic shock

Churg-Strauss syndrome (CSS) is a multisystem disorder characterised by asthma, prominent peripheral blood eosinophilia, and vasculitis signs. We report the case of a 22 year-old man admitted to the intensive care unit for acute myocarditis complicated with cardiogenic shock. Eosinophilia, history of asthma, lung infiltrates, paranasal sinusitis, glomerulonephritis, and abdominal pain suggested the diagnosis of CSS. Cardiac MRI confirmed cardiac involvement with a diffuse subendocardial delayed enhancement of the left ventricular wall, and a left ventricular ejection fraction (LVEF) of 30%. Acute myocarditis was confirmed with myocardial biopsy. The patient was successfully treated with systemic corticosteroids, intravenous cyclophosphamide, vasopressor inotropes, intra-aortic balloon pump and mechanical ventilation, and was discharged 21 days later. One year after diagnosis, the patient was asymptomatic. The eosinophilic cell count was normal. Follow-up MRI at one year showed LVEF of 40% with persistent delayed enhancement. Cardiac involvement by CSS requires immediate therapy with corticosteroids and cyclophosphamide, which may allow recovery of the cardiac function.     

Scleroderma renal crisis precipitated by steroid treatment in systemic lupus erythematosus and scleroderma overlap syndrome

Introduction: Connective tissue disorders can overlap in various ways. Patients may present with features of more than one specific disease without satisfying the diagnostic criteria and thereafter evolve into a specific disease entity. Occasionally, patients may fulfil simultaneously the diagnostic criteria of two or more diseases. Several cases of systemic sclerosis (SSc) and systemic lupus erythematosus (SLE) overlap syndrome have been reported. SLE patients often develop lupus nephritis, the treatment of which is based on immunosuppression with corticosteroids (CS) and cytotoxic drugs. However, the use of high dose of CS has been associated with scleroderma renal crisis (SRC) in patient with SSc. Case report: a 43-year-old woman presented to the nephrology department of the Military hospital in Rabat, Morocco, in August 2011 with progressive dyspnea and oliguria. She was diagnosed as SLE and scleroderma overlap syndrome based on clinical and serological markers. Renal biopsy showed lupus nephritis. Immunosuppression consisting of high-dose steroid and cyclophosphamide pulses was given. There was response to treatment but 15 days later the course of the disease was complicated by scleroderma renal crisis evidenced by elevated blood pressure, deteriorating kidney function, hemolysis and thrombocytopenia. The patient was treated with perindopril and rapid reduction of steroid doses. This was followed by correction of hemolysis and thrombocytopenia. Two months later, the patient was off dialysis, but had chronic renal insufficiency with an estimated GFR of 25 ml/minute. Conclusion: This report describes the occurrence of SRC in a patient with lupus nephritis and SSc/ SLE overlap syndrome who was treated by CS and cyclophosphamide. Key words: Systemic Sclerosis; Lupus Erythematosus; Overlap Syndrome; Scleroderma Renal Crisis; Corticosteroids.     

Abetimus sodium for renal flare in systemic lupus erythematosus: results of a randomized, controlled phase III trial

OBJECTIVE: To investigate whether treatment with abetimus delays renal flare in patients with lupus nephritis. Secondary objectives included evaluation of the effect of abetimus on C3 levels, anti-double-stranded DNA (anti-dsDNA) antibody levels, use of high-dose corticosteroids and/or cyclophosphamide, and major systemic lupus erythematosus (SLE) flare. METHODS: We conducted a randomized, placebo-controlled study of treatment with abetimus at 100 mg/week for up to 22 months in SLE patients. Three hundred seventeen patients with a history of renal flare and anti-dsDNA levels >15 IU/ml were randomized to a treatment group (158 abetimus, 159 placebo); 298 (94%) were enrolled in the intent-to-treat (ITT) population (145 abetimus, 153 placebo), based on the presence of high-affinity antibodies for the oligonucleotide epitope of abetimus at baseline screening. RESULTS: Abetimus did not significantly prolong time to renal flare, time to initiation of high-dose corticosteroid and/or cyclophosphamide treatment, or time to major SLE flare. However, there were 25% fewer renal flares in the abetimus group compared with the placebo group (17 of 145 abetimus-treated patients [12%] versus 24 of 153 placebo-treated patients [16%]). Abetimus treatment decreased anti-dsDNA antibody levels (P < 0.0001), and reductions in anti-dsDNA levels were associated with increases in C3 levels (P < 0.0001). More patients in the abetimus group experienced > or =50% reductions in proteinuria at 1 year, compared with the placebo group (nominal P = 0.047). Trends toward reduced rates of renal flare and major SLE flare were noted in patients treated with abetimus who had impaired renal function at baseline. Treatment with abetimus for up to 22 months was well tolerated. CONCLUSION: Abetimus at 100 mg/week significantly reduced anti-dsDNA antibody levels but did not significantly prolong time to renal flare when compared with placebo. Multiple positive trends in renal end points were observed in the abetimus treatment group.     

Dramatic improvement of left ventricular function after cytotoxic therapy in lupus patients with acute cardiomyopathy: report of 6 cases.

Although lupus cardiomyopathy is thought to be clinically uncommon, we encountered 6 patients with systemic lupus erythematosus (SLE) over a 10 year period who had severe left ventricular dysfunction and showed remarkable improvement in their cardiac function after cytotoxic therapy. All patients met the American College of Rheumatology criteria for classification of SLE and presented with signs of severe biventricular failure relatively early in their disease. Concurrent manifestations of SLE at the time of cardiomyopathy included rash, arthritis, myalgias, pleuritis, pericarditis, and nephritis. Four of the 6 patients were taking prednisone 20 mg/day at the time heart failure developed. In all cases the CPK were normal. Evaluation of cardiac function by echocardiogram and/or radionuclide gated blood pool scintigraphy revealed a severe depression of ventricular function with initial left ventricular ejection fraction (LVEF) ranging from 11 to 34% (mean 19%). Within 6 months of initiation of cytotoxic treatment all patients showed a dramatic response: the post-treatment LVEF ranged from 25 to 55%. This series of patients suggests that cardiomyopathy may be a more common complication of SLE than previously reported. Cardiomyopathy occurs relatively early in the course of SLE, may lead to severe cardiac dysfunction despite corticosteroid therapy, and appears to be responsive to cytotoxic therapy.     

Multiple myeloma complicating the course of seronegative systemic lupus erythematosus

A patient with a 20-year history of clinical systemic lupus erythematosus (SLE) who later developed multiple myeloma is described. SLE was diagnosed on the basis of a butterfly rash, photosensitivity, nondeforming arthritis, pleuropericarditis, and alopecia. However, the patient has never had LE cells, antinuclear antibody, or depressed complement. The patient was treated with intermittent courses of corticosteroids over a 20-year period with good results. Multiple myeloma, diagnosed by bone marrow biopsy, has responded favorably to therapy with L-phenylalanine mustard and prednisone.     

Postoperative pneumococcal cellulitis in systemic lupus erythematosus

This paper reports a case of nosocomial pneumococcal cellulitis that developed following a lymph-node biopsy in a woman being treated with high-dose intravenous corticosteroids for systemic lupus erythematosis (SLE). Her rapid and severe clinical deterioration was similar to that caused by group A streptococcus. The risk factors for the development of nosocomial pneumococcal cellulitis as a complication of SLE are reviewed and preventive measures discussed.     

Successful treatment of chronic lupus myocarditis with prednisolone and mizoribine

A 36-year-old female patient who was diagnosed with chronic myocarditis as an initial manifestation of systemic lupus erythematosus (SLE) was admitted to our hospital. At her third occurrence of heart failure, we performed an endomyocardial biopsy and proved chronic myocarditis with SLE. Subsequently, she was treated with prednisolone and the immunosuppressive agent mizoribine (MZR), and her cardiac function improved. We describe for the first time treatment with MZR for chronic cardiac involvement of SLE.
