After 2 years of steroid therapy that had effectively controlled her systemic lupus erythematosus, a 37-year-old woman presented with fever, erythema (face, upper chest), and low CH50. Increased oral steroid (prednisolone from 15 mg to 40 mg) and intravenous methylprednisolone (mPSL) (80 mg for 3 days) alleviated these symptoms except for the fever. Subsequently, the patient's fever worsened and leukocytopenia, abnormal liver function, lymphadenopathy (neck, axilla), and salivary gland swelling developed. Lymph node histology revealed features characteristic of Kikuchi-Fujimoto's disease (KFD). Laboratory examinations showed WBC 600/microliter, Hb 9.5 g/dl, platelets 90,000/microliter, GOT 766 IU/l, GPT 646 IU/l, LDH 4,228 IU/l, TG 1,622 mg/dl, and ferritin 6,330 ng/ml. Serum interferon gamma was also elevated (673 U/ml). Because a bone marrow smear revealed hemophagocytosis, mPSL pulse therapy (1 g for 3 days) was started for treatment of hemophagocytic syndrome. The fever promptly disappeared, and the patient's clinical symptoms resolved within 2 weeks. The abnormal laboratory data related to KFD and hemophagocytosis returned to normal within 4 weeks after the initiation of mPSL pulse therapy. We speculated that the hemophagocytosis and salivary gland involvement in this patient were also symptoms of KFD. This case indicated that corticosteroid pulse therapy is effective for KFD with serious clinical symptoms.

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.

To investigate the relationship between serum ferritin and disease activity in systemic lupus erythematosus (SLE), we enrolled 128 patients with SLE (18 males and 110 females). Twenty-eight patients (2 males and 26 females) with rheumatoid arthritis (RA) served as controls. The SLE patients were subdivided into three groups according to Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) scores: groups A (0-5), B (6-9), and C (> or =10). We prospectively evaluated 48 SLE patients before and after treatment. Serum ferritin and anti-dsDNA antibody were measured by radioimmunometric assay. C-reactive protein (CRP) was measured quantitatively by immunonephelometry. Complements 3 and 4 (C3 and C4) were measured by nephelometry. Serum levels of ferritin during the more active stage of SLE (group C) exceeded those of RA patients and patients at less active stages of SLE (groups A and B). There were no significant differences between RA patients and groups A and B. Serum ferritin was elevated especially in serositis and hematologic manifestation. In this prospective study, changes in SLEDAI scores before and after treatment correlated significantly with serum ferritin levels and inversely to C3 and C4 levels. We confirm that serum ferritin levels can be a useful marker of disease activity in SLE patients.

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.

The success of apheresis treatment is often measured as a decrease in the detected antibodies and an improvement in different disease-related scores. Sometimes, however, the seriousness of the disease does not correlate with the antibody level. During a period of 8 years, 15 patients (3 myasthenia gravis, 1 multiple sclerosis, 2 systemic lupus erythematosus, 3 alloimmunized kidney transplant, 6 rheumatoid arthritis) were treated by protein A immunoadsorption. Lymphocyte subpopulations (activated T cells, cytolytic T cells, B cells, natural killer cells) and inflammatory proteins (ferritin, C-reactive protein, alpha1-antitrypsin, alpha2-macroglobulin) were analyzed. After observing clinical outcomes, the patients could be divided into 2 groups, respectively: Group 1, responding patients with remission of disease; and Group 2, delayed-responding patients, who required chronic treatment. Group 1 patients characteristically showed a greater increase in activated T and cytolytic T cells which correlated with a greater decrease of B cells. It might be possible that protein A immunoadsorption induced immunomodulation. Further immunological investigation is required to verify these findings.

TALL-1 is a member of the tumor necrosis factor family that binds to BCMA, TACI, and BAFF-R, three receptors mostly expressed by mature B lymphocytes. Previous studies have shown that the TALL-1 signaling is critically involved in B cell proliferation, maturation, and progression of lupus-like, autoimmune diseases. In this report, we performed cDNA subtractive hybridization experiments to identify downstream genes up-regulated by TALL-1. These experiments indicated that 10 genes, including interleukin (IL)-10, lymphocyte activation gene-1 (LAG-1), GCP-2, PBEF, ferritin, PIM-2, TFG, CD27 ligand, DUSP5, and archain, were up-regulated at the mRNA level by TALL-1 stimulation in B lymphoma RPMI-8226 cells and/or primary B lymphocytes. We also demonstrated that TALL-1 activated transcription of IL-10 and LAG-1 in a nuclear factor-kappaB-dependent manner in reporter gene assays. Moreover, our findings indicated BAFF-R, but not TACI, could dramatically up-regulate IL-10 secretion by RPMI-8226 cells. The identification of TALL-1-up-regulated genes will help explain the mechanisms of TALL-1-triggered biological and pathological effects and to identify molecular targets for intervention of lupus-like autoimmune diseases.

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.

Neonatal hemochromatosis is an enigmatic disease. Little is known about iron metabolism in this disease, including the tissue concentration of ferritin or its H and L subunit ratio. The authors report the tissue iron, ferritin, and ferritin subunit content of a child who died at 5 weeks of neonatal hemochromatosis. The child was born at 29 weeks gestation to a mother with lupus, sickle cell trait, and gestational diabetes. The child's severe liver dysfunction led to the clinical diagnosis of neonatal hemochromatosis at 1 week of age. Despite aggressive support, including red cell transfusions and chelation, the child died of an intracranial hemorrhage. Autopsy showed liver fibrosis and iron staining characteristic of neonatal hemochromatosis. Autopsy liver tissue was compared to age-matched control tissue. Soluble protein was analyzed by the Bradford method. Soluble iron (over 90% of total iron) was analyzed by the o-phenanthroline complex. Tissue ferritin and human ferritin controls (Calzyme) were analyzed by Western blotting after SDS-PAGE, identified with sheep anti-human ferritin antibodies (The BindingSite) secondary antibody-fluorescence for detection, and quantified using the Molecular Dynamics Storm 840 phosphorimager and ImageQuant software. Protein, iron, and total ferritin were similar in the normal and neonatal hemochromatosis liver tissues. Ferritin subunits, however, showed an increased H/L-subunit ratio compared to an age-matched control. This first report of a marked increase in the ferritin H/L-subunit ratio may point to an underlying mechanism of disease in this enigmatic disorder.

Hemophagocytic syndrome (HPS) is a life-threatening disorder characterized by pancytopenia and activation of macrophages. Recently, corticosteroid incorporated in lipid microspheres (liposteroid) has been reported to be taken up by macrophages and to suppress their functions. Here we present a case of systemic lupus erythematosus complicated by HPS that was successfully treated with liposteroid in addition to an oral corticosteroid and intravenous high-dose cyclophosphamide therapy. The serum levels of tumor necrosis factor-alpha and ferritin that have been reported to be associated with activity of macrophages remarkably reduced after liposteroid administration. This case suggests that liposteroid is useful for the treatment of HPS.

A 54-year-old man of Persian origin presented to our department with a 1-year history of ulcers on the right leg that had been unresponsive to numerous topical treatments, accompanied by lymphedema of the right leg. Medical history included hypergonadotropic hypogonadism, which had not been further investigated. He was treated for 20 years with testosterone IM once monthly, which he stopped a year before the current hospitalization for unclear reasons. The patient reported no congenital lymphedema. Physical examination revealed two deep skin ulcers (Figure 1) on the right leg measuring 10 cm in diameter with raised irregular inflammatory borders and a boggy, necrotic base discharging a purulent hemorrhagic exudate. Bilateral leg pitting edema and right lymphangitis with lymphadenitis were noted. He had low head hair implantment, sparse hair on the body and head, hyperpigmentation on both legs, onychodystrophia of the toenails (mainly the large toe and less prominent on the other toes), which was atrophic lichen-planus-like in appearance and needed no trimming (Figure 2), normal hand nails, oral thrush, and angular cheilitis. Other physical findings were gynecomastia, pectus excavatum, small and firm testicles, long extremities, asymmetrical goiter, systolic murmur 2/6 in left sternal border, and slow and inappropriate behavior. The patient's temperature on admission was 39 degrees C. Blood cultures were negative for bacterial growth. Results of laboratory investigations included hemoglobin (11.2 g/dL), hematocrit (26.8%), normal mean corpuscular volume and mean corpuscular hemoglobin volume, and red blood cell distribution width (16%). Blood smear showed spherocytes, slight hypochromia, anisocytosis, macrocytosis, and microcytosis. Blood chemistry values were taken for iron (4 micro g/dL [normal range 40-150 micro g/dL]), transferrin (193 mg/dL [normal range 220-400 mg/dL]), ferritin (1128 ng/mL [normal range 14-160 ng/mL]), transferrin saturation (1.5% [normal range 20%-55%]), serum folate (within normal limits), and vitamin B12 (within normal limits). Direct Coombs' test equaled positive 2 + IgG. All these values indicated anemia of chronic diseases combined with hemolytic anemia. Further blood work-up tested antinuclear antibody (positive <1:80 homogeneous pattern), rheumatoid factors (143 IU/mL [positive >8.5 IU/mL]), C-reactive protein (286 mg/L [normal range 0-5 mg/L]), anticardiolipin IgM antibody (9.0 monophosphoryl lipid U/mL [normal range 0-7.00 MPL U/mL]) and antithrombin III activity (135% [normal range 74%-114%]). Results of other blood tests were within normal limits or negative, including lupus anticoagulant, beta2 glycoprotein, anticardiolipin IgG Ab, anti-ss DNA Ab, C3, C4, anti-RO, anti-LA, anti-SC-70, anti-SM Ab, P-ANCA, C-ANCA, TSH, FT4, anti-T microsomal, antithyroglobulin, protein C activity, protein S free, cryoglobulins, serum immunoelectrophoresis, VDRL, hepatitis C antibodies, hepatitis B antigen, and human immunodeficiency virus. Endocrinological work-up examined luteinizing hormone (22.9 mIU/mL [normal range for adult men 0.8-6 mIU/mL]), follicle stimulating hormone (49.7 mIU/mL [normal range for adult men 1-11 mIU/mL]), testosterone (0.24 ng/mL [normal range for adult men 2.5-8.0 ng/mL]), bioavailable testosterone (0.02 ng/mL [normal range for adult men >0.6 ng/mL]), and percent bioavailable test (8.1% [normal value >20%]). These results indicate hypergonadotropic hypogonadism. Plasminogen activator inhibitor 1 was 6 U (normal value 5-20 U/mL). Karyotyping performed by G-banding technique revealed a 47 XXY karyotype, which is diagnostic of Klinefelter's syndrome. Doppler ultrasound of the leg ulcers disclosed partial thrombus in the distal right femoral vein. X-rays and bone scan displayed osteomyelitis along the right tibia. Histological examination of a 4-mm punch biopsy from the ulcer border revealed hyperkeratosis, acanthosis, hypergranulosis, and mixed inflammatory infiltrate containing eosinophils compatible with chronic ulcer. Multiple vessels were seen, compatible with a healing process. Direct immunofluorescence of the biopsy revealed granular IgM in the dermo-epidermal junction. Indirect immunofluorescence was negative. Thyroid function tests showed normal thyroid stimulating hormone and free throxine4. Multinodular goiter was seen on thyroid scan and ultrasound. Thyroid fine needle aspiration was compatible with multinodular goiter (normal follicular cells, free colloid, macrophages with pigment). IV treatment with amoxicillin-clavulanic acid 1 g t.i.d. was administered for 2 weeks, with a decrease in temperature and normalization of the leukocyte level. Oral antibiotic treatment with amoxicillin-clavulanic acid was continued for 10 more days, followed by 25 days of ciprofloxacin for the osteomyelitis. Local treatment included saline soakings followed by application of Promogran (Johnson & Johnson, New Brunswick, NJ) and Kaltostat (ConvaTec Ltd., a Bristol-Myers Squibb Company, New York, NY) with slight improvement. At the same time, the patient was treated with warfarin sodium due to deep vein thrombosis under international normalized ratio 2-3. The patient was treated with IM testosterone once monthly for 1 year, which resulted in a reduction in the diameter and depth of the leg ulcers (Figure 3). Blood tests were not performed for follow-up of the immune state.
