Ankylosing spondylitis presenting with macrophage activation syndrome

Macrophage activation syndrome (MAS), which can also be considered as reactive hemophagocytic syndrome (HPS), is a rare and potentially fatal complication of rheumatic diseases. We describe a 42-year-old woman in whom MAS developed as a complication of ankylosing spondylitis (AS). She suffered from fever and low back pain before admission. Laboratory findings were pancytopenia, abnormal liver enzymes, increased ferritin levels, and positive for B27. Hyperplasia of hemophagocytic macrophages was confirmed in her bone marrow. High-dose steroids therapy resulted in clinical and laboratory improvements. In this patient, there was no possible causative factor of HPS (such as viral infection, lymphoma, and systemic lupus erythematosus) except the presence of AS. There have been no previously reported cases describing the relationship between AS and HPS. This case indicates that attention should be given to the possibility that certain patients with AS-associated cytopenia may display accompanying intramedullary hemophagocytic phenomena.     

Simultaneous presentation of hemophagocytic syndrome and mesenteric vasculitis in a patient with systemic lupus erythematosus

We report an 18-year old female patient with systemic lupus erythematosus (SLE), who developed fever, pancytopenia, abdominal pain, and watery diarrhea. Computed tomography (CT) and bone marrow aspirate revealed lupus mesenteric vasculitis (LMV) and hemophagocytic syndrome (HPS). Serologic tests for Epstein–Barr virus (EBV) indicated its reactivation. This case demonstrates that HPS and concomitant LMV associated with viral reactivation can occur as clinical manifestations of SLE flare.     

Simultaneous presentation of hemophagocytic syndrome and mesenteric vasculitis in a patient with systemic lupus erythematosus

Abstract

We report an 18-year old female patient with systemic lupus erythematosus (SLE), who developed fever, pancytopenia, abdominal pain, and watery diarrhea. Computed tomography (CT) and bone marrow aspirate revealed lupus mesenteric vasculitis (LMV) and hemophagocytic syndrome (HPS). Serologic tests for Epstein–Barr virus (EBV) indicated its reactivation. This case demonstrates that HPS and concomitant LMV associated with viral reactivation can occur as clinical manifestations of SLE flare.     

Mycobacterium avium complex-associated hemophagocytic syndrome in systemic lupus erythematosus patient: report of one case

Hemophagocytic syndrome (HPS) in systemic lupus erythematosus(SLE) patients has not commonly been reported. In this case study, we report the first case of Mycobacterium avium complex (MAC)-associated hemophagocytic syndrome in a patient with systemic lupus erythematosus (SLE). This SLE patient, a 15-year-old girl, had been on a high dose of prednisolone (> 0.5mg/kg/day) for more than 3 years. She presented with a spiking fever, hepatosplenomegaly, pancytopenia, hyperferritinemia and adult respiratory distress syndrome. Bone marrow examination revealed hemophagocytosis as well as non-caseating granulomatosis. There was no indication of SLE fare-up. She responded poorly to initial treatment with methyl-prednisolone, intravenous immumoglobulin, etoposide, and drugs for Mycobacterium tuberculosis including rifampin, ethambutol, isoniazid and pyramide. However, gastric lavage culture revealed MAC. Following treatment with clarithromycin, ciprofloxacin and amikacin, her condition gradually improved and she was discharged 3 months after admission. In SLE patients with pancytopenia and hyperferritinemia, MAC-associated HPS should be considered in the differential diagnosis.     

Transient myopia with severe chemosis as an initial manifestation of systemic lupus erythematosus

A 24-year-old woman suffered from blurred vision and periorbital edema with remittent fever. She was diagnosed as having systemic lupus erythematosus (SLE), complicated with myopia and retinopathy and severe chemosis. Antiphospholipid syndrome (APS), hemophagocytic syndrome, and liver involvement were also proven. We considered that APS might cause chemosis as a result of thrombosis-induced perfusion failure in the conjunctiva. In such cases, APS should be considered and anticoagulation therapy associated with steroid therapy should be initiated. In systemic lupus erythematosus (SLE), chemosis, severe hepatitis, and hemophagocytic syndrome (HPS) are rare complications. It is well known that many cases of SLE are complicated with antiphospholipid syndrome (APS), which causes arteriovenous thrombosis. We report a case of SLE with transient myopia and severe chemosis complicated with severe hepatitis and HPS. As this patient had antiphospholipid antibodies, these ocular complications were considered to be related to APS. Received: August 23, 2000 / Accepted: November 24, 2000     

Rituximab was effective on refractory thrombotic thrombocytopenic purpura but induced a flare of hemophagocytic syndrome in a patient with systemic lupus erythematosus

We report the case of a patient with systemic lupus erythematosus (SLE) who first revealed hemophagocytic syndrome (HPS), which was treated successfully with glucocorticoid and intravenous cyclophosphamide. The patient then demonstrated refractory thrombotic thrombocytopenic purpura (TTP) with normal a disintegrin and metalloprotease with thrombospondin motifs (ADAMTS)-13 activity that responded well to rituximab. After rituximab treatment, the patient showed a flare of HPS that was controlled by additional intravenous cyclophosphamide treatment. This case showed that TTP with normal ADAMTS-13 activity is B-cell dependent and indicated that B-cell depletion might exacerbate some autoimmune conditions in SLE.     

Successful treatment of reactive hemophagocytic syndrome by plasmapheresis and high-dose γ-globulin in a patient with systemic lupus erythematosus

A 31-year-old woman who had been administered corticosteroid and immunosuppressive agents for systemic lupus erythematosus (SLE) without flare-up was diagnosed as having reactive hemophagocytic syndrome (HPS) with severe disseminated intravascular coagulation. The causative underlying disease was uncertain, but it was not the SLE itself. Her fulminant HPS with increased serum ferritin and inflammatory cytokines (sIL-2R, TNF-α, IL-6, and IFN-γ) was successfully treated with plasmapheresis and high-dose γ-globulin therapy. Received: December 24, 1999 / Accepted: June 28, 2000     

Intravascular lymphoma associated with systemic lupus erythematosus

We report a case of systemic lupus erythematosus (SLE) associated with intravascular (angiotropic) lymphoma. A 27‐year‐old woman had been suffering from uncontrolled severe eruptions for a long time and was admitted because of high fever due to hemophagocytic syndrome (HPS). As her SLE had not been well‐controlled by moderate doses of steroids and azathioprine, autoimmune associated HPS was first considered. She was initially treated with steroid pulses and γ‐globulin for HPS. However, chromosomal analysis of bone marrow cells revealed severe abnormalities. After malignant lymphoma‐associated HPS was diagnosed, chemotherapy was commenced in the intensive care unit with artificial respiration and continuous hemodiafiltration. The patient died of cerebral infarction at day 45. It is suggested that the SLE itself was associated with the development of the intravascular lymphoma rather than due to the azathioprine.     

Systemic lupus erythematosus with bilateral salivary gland swelling and clouding of consciousness accompanied by hemophagocytic syndrome--a study of serial determination of serum cytokines

We investigated changes in various serum cytokines in a case of systemic lupus erythematosus (SLE) accompanied by hemophagocytic syndrome (HPS). The patient, a 15-year-old male, presented in December 1998 with bilateral salivary gland swelling and a history of fever continuing for more than 10 days. After admission, cerebellar ataxia and clouding of consciousness developed. Laboratory examinations revealed leukopenia, thrombocytopenia, high serum LDH and ferritin, hypercytokinemia, and prominent hemophagocytosis in the bone marrow. Given these findings and positive titers of antinuclear antibody, hypocomplementemia, proteinuria and pericarditis, a diagnosis of HPS with associated SLE was made. The patient was treated with high dose methylprednisolone followed by oral prednisolone and cyclosporine. The patient's clinical symptoms, abnormal blood and urine laboratory data consequently improved, and no recurrence of the symptoms has been documented. However, hemophagocytosis in bone marrow recurred with concomitantly increased serum levels of IL-6 and IL-1 beta. This case indicated that aberrant production of these inflammatory cytokines might be involved in HPS in autoimmune disease.     

Hemophagocytic syndrome in elderly patients with underlying autoimmune diseases

In patients with autoimmune disease-associated hemophagocytic syndrome (AAHS), the clinical features may differ from hemophagocytic syndrome (HPS) of other etiologies, and new criteria for AAHS have been proposed. Since bone marrow (BM) circumstances are changed according to aging, here we reviewed retrospectively our cases with AAHS in elderly patients, including two systemic lupus erythematosus (SLE), three Evans syndrome, one rheumatoid arthritis (RA), one Hashimoto thyroiditis, and one autoimmune pancreatitis. Although only two SLE patients were diagnosed as HPS by the classical criteria, the remaining patients except one RA met the criteria for AAHS. Seven patients except one SLE patient showed good response to therapy and demonstrated positive autoantibodies to blood cells, lower serum ferritin levels, and increased erythroblastic islands in the BM. We consider the diagnosis of AAHS should be carefully made when macrophages phagocytosing blood cells are observed in BM smear without hyperferritinemia in elderly patients with autoimmune diseases.     

Reactive hemophagocytic syndrome in a case of systemic lupus erythematosus that was diagnosed by detection of hemophagocytosing macrophages in peripheral blood smears

A 38-year-old woman with pancytopenia and liver dysfunction was diagnosed with active systemic lupus erythematosus (SLE). On days 9 and 10 of admission, peripheral blood smears showed macrophages phagocytosing platelets, and reactive hemophagocytic syndrome (HPS) was diagnosed. Hemophagocytic syndrome was successfully treated with high-dose prednisolone therapy and one course of methylprednisolone pulse therapy. Detection of hemophagocytosing macrophages in peripheral blood smears would be a useful and noninvasive method of diagnosing SLE-associated HPS.     

Systemic lupus erythematosus complicated by cytomegalovirus-induced hemophagocytic syndrome and colitis

Here, we report a case of systemic lupus erythematosus (SLE) complicated by cytomegalovirus (CMV)-induced hemophagocytic syndrome (HPS) and colitis. A 44-year-old woman with SLE was treated with corticosteroid and cyclophosphamide for lupus nephritis. Although her lupus nephritis improved, fever, progressive pancytopenia and intestinal bleeding were observed. A bone marrow aspiration showed an increase in mature histiocytes with hemophagocytosis. In addition, a colonoscopy showed hemorrhagic colitis with ulcer and the biopsy specimen from the colon revealed typical CMV cells with CMV inclusions confirmed by immunohistochemistry. Furthermore, a large number of CMV antigen-positive leukocytes was detected, suggesting an active CMV infection. CMV infection is serious in compromised hosts. Therefore clinicians should be aware of the clinical settings in which this infection can arise and the target organs potentially affected in order to initiate the appropriate intervention.     

Successful use of etanercept in the treatment of acute lupus hemophagocytic syndrome

Hemophagocytic syndrome has been reported to be associated with systemic lupus erythematosus. A 25-year-old woman with systemic lupus erythematosus developed hemophagocytic syndrome that was refractory to the combination therapy with high-dose corticosteroid, cyclosporine, and high-dose intravenous immunoglobulin, and successfully treated with the tumor necrosis factor inhibitor, etanercept. This case report provided the first observation that etanercept may be useful for the treatment of hemophagocytic syndrome associated with systemic lupus erythematosus refractory to conventional therapy.     

A case of systemic lupus erythematosus with hemophagocytic syndrome and cytophagic histiocytic panniculitis]

A 23-year-old man, admitted because of high fever, polyarthralgia, butterfly rash and chest pain, was diagnosed as systemic lupus erythematosus (SLE) from the findings of positive antinuclear antibody and anti-DNA antibody. He was treated with 60 mg prednisolone daily, but as reducing the dose, white blood cell counts and platelet counts were decreased and fever, polyarthralgia, decrease of complements, increase of ferritin, hepato-splenomegaly and liver dysfunction were observed. Bone marrow specimen revealed phagocytosis of blood cells by histiocytes and he was diagnosed as hemophagocytic syndrome(HPS) due to active SLE. Methylprednisolone pulse therapy was effective temporarily, HPS recurred while reducing steroid, and cyclosporin was added. After a temporary remission, marked extensive swelling in the face appeared suddenly. Facial skin biopsy showed necrosis of fat cells and hemophagocytosis by histiocytes. Accordingly, he was diagnosed as panniculitis due to HPS and was treated successfully with intravenous cyclophosphamide pulse therapy and high dose of gammaglobulin. Several cases of HPS due to SLE have been reported recently, but this is a rare case of cytophagic histiocytic panniculitis (CHP) due to SLE.     

Case report of systemic lupus erythematosus patient with hemophagocytic syndrome, treated with plasma exchange, with specific reference to clinical profile and serum cytokine levels]

A 42-year-old woman was diagnosed as systemic lupus erythematosus (SLE), because of the findings of polyarthritis, leukopenia, positive antinuclear antibody, and positive anti DNA antibody. She was treated with predonisolone (PSL) at 10 mg per day. She was admitted to our hospital on October 2000 because of spiking high fever, skin eruption, and lymph node swelling. Since her illness of SLE was considered to be worsening, high dose of corticosteroids were given. However, high fever persisted and liver dysfunction was developed with increased serum ferritin. Her bone marrow smear showed hemophagocytosis. We made a diagnosis of hemophagocytic syndrome (HPS) complicated by disseminated intravascular coagulation (DIC). HPS was thought to be induced by viral infection, even though causative viral infection was not detected. Her general condition worsened with persistent high fever and liver dysfunction. Plasma exchange was carried for two consecutive days, followed by cyclosporine A and lipo-dexamethasone, which improved her fever rapidly. Her general condition gradually improved. Serum levels of ferritin, soluble interleukin 2 receptor (sIL 2-R), interferon-gamma and interleukin 6 decreased associated with improvements of her clinical condition. We thought plasma exchange could be effective to decrease serum levels of cytokine, which was suggested to be the pathogenic to HPS. However serum levels of IFN-gamma and IL 6 after plasma exchange did not change in this case. Further studies are required to confirm the effects of plasma exchange for HPS.     

Influenza virus B-associated hemophagocytic syndrome and recurrent pericarditis in a patient with systemic lupus erythematosus

Abstract

We report a 24-year-old male with systemic lupus erythematosus (SLE) who developed influenza virus B-associated hemophagocytic syndrome and cardiac tamponade. Although the patient’s general condition improved after steroid pulse therapy and pericardiocentesis, pericardial effusion re-accumulated. Colchicine and aspirin were administered, together with prednisolone, after which no further relapses occurred. This was a rare case of severe influenza-associated hemophagocytic syndrome and steroid-resistant pericardial effusion in an SLE patient.     

A case of acute pericarditis with hemophagocytic syndrome,cytomegalovirus infection and systemic lupus erythematosus

Hemophagocytic syndrome, cytomegalovirus infection and systemic lupus erythematosus (SLE) would each be critical diseases separately. Viral infections, autoimmune diseases or malignancies can complicate the Hemophagocytic syndrome. Cytomegalovirus infection is known to be prevalent in immune compromised hosts, and can exacerbate the symptoms of systemic lupus erythematosus. A 25-year-old man presented with fever and acute pericarditis with the hemophagocytic syndrome, cytomegalovirus infection and systemic lupus erythematosus; all developed concurrently at the onset of illness. With treatment, using ganciclovir and glucocorticoid medication the patient improved. Here we report this rare case and review the medical literature.     

Reflections on the management of reproductive failure in the antiphospholipid syndrome--the clinician's perspective

It is well known that women with systemic lupus erythematosus (SLE) who have antiphospholipid antibodies (aPL) are at increased risk for pregnancy loss. Additionally, other reproductive processes, such as unexplained infertility and implantation failure after in vitro fertilization and embryo transfer may be affected by aPL. Thus, clinical manifestations of the so-called 'gynaeco-obstetrical antiphospholipid syndrome' have been expanded into the concept of the 'reproductive autoimmune failure syndrome'. However, this is still a matter of debate with no general agreement with respect to both pathophysiological significance of the presence of aPL and patient management. This article analyses a number of controversies in the management of reproductive failure potentially associated with aPL in order to help clinicians dealing with such condition in daily clinical practice.     

Influenza virus B-associated hemophagocytic syndrome and recurrent pericarditis in a patient with systemic lupus erythematosus

We report a 24-year-old male with systemic lupus erythematosus (SLE) who developed influenza virus B-associated hemophagocytic syndrome and cardiac tamponade. Although the patient’s general condition improved after steroid pulse therapy and pericardiocentesis, pericardial effusion re-accumulated. Colchicine and aspirin were administered, together with prednisolone, after which no further relapses occurred. This was a rare case of severe influenza-associated hemophagocytic syndrome and steroid-resistant pericardial effusion in an SLE patient.     

The acute lupus hemophagocytic syndrome

OBJECTIVE: To characterize an unusual mode of presentation of systemic lupus erythematosus: acute and severe pancytopenia related to reactive hemophagocytosis. DESIGN: Retrospective case series. SETTING: Two general community hospitals in Hong Kong. PATIENTS: Six patients presenting with a reactive hemophagocytic syndrome, identified over a 3.5 year period, diagnosed with systemic lupus erythematosus according to the criteria of the American Rheumatism Association. RESULTS: In addition to severe pancytopenia and marrow hemophagocytosis, other characteristic features were fever, hypocomplementemia, high antinuclear antibody titer, and cutaneous and visceral vasculitis. There was no evidence of an underlying infection. The pancytopenia responded dramatically to treatment with steroids. CONCLUSION: Recognition of the acute lupus hemophagocytic syndrome and distinction from an infection-associated hemophagocytic syndrome is important because it responds well to steroid therapy. The evaluation of patients presenting with a hemophagocytic syndrome should include serologic tests for systemic lupus erythematosus.
