Two patients with severe arthralgia associated with palmoplantar pustulosis (PPP) were treated with oral cyclosporine A (CsA). Clinical efficacy was assessed on a 0-4 point scale for erythema, desquamation, infiltration, and pustulation, and on a 0-3 point pain scale. Skin lesions and arthralgia improved within twelve weeks with low dose CsA ranging from 2.1 to 2.2 mg/kg/day. High levels of plasma interleukin-6 (IL-6) were reduced to the normal range.

In a phase I/II study, 11 patients with marrow failure (10 with acquired aplastic anaemia and one with pancytopenic Fanconi anaemia) were treated with recombinant human interleukin-6 (rhIL-6) to assess the safety and tolerability of rhIL-6 and its effects on peripheral blood counts, bleeding complications and transfusion requirements. All patients with acquired aplastic anaemia were refractory to immunosuppressive treatment or had relapsed after immunosuppressive therapy and were not bone marrow transplantation candidates. Recombinant hIL-6 was to be given as a once-daily subcutaneous injection for 28 d at doses ranging from 0.5 to 5.0 micrograms/kg. After an observation period of 2 weeks, five patients received a second treatment course of 28 d. Only one patient had a sustained increase in platelet count from 18,000 to 72,000/microliters. Bleeding occurred in four patients and caused premature discontinuation of rhIL-6 therapy in three patients. A deterioration of pre-existing anaemia was observed in nine patients. No significant changes of leucocyte counts were observed during the first cycle. During the second cycle the peripheral blood monocyte counts decreased significantly. No significant changes in bone marrow cellularity were observed. Recombinant hIL-6 induced a dose-dependent increase in acute-phase reactants in all patients. Other adverse events included fever, headache, arthralgia, tachycardia and hypertension. In conclusion, rhIL-6 given alone at low doses does not increase platelet counts in the majority of patients with aplastic anaemia and can precipitate a sudden worsening of pre-existing anaemia and thrombocytopenia. This study was discontinued prematurely on account of the toxicity of rhIL-6 seen in patients with aplastic anaemia.

We reported a 59-year-old woman who received a diagnosis of psoriasis vulgaris at the age of 35 and had been under medical treatment. She was admitted to our department on August 16, 1993 because of lymphadenopathy, arthralgia and neuralgia. We observed cervical and axillar lymphadenopathy 1-3 cm in diameter, anemia and leukothrombocytosis. Elevated levels of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and immunoglobulin G (IgG), but not M-protein were observed by immunological analysis of the serum. Bone marrow aspiration biopsy revealed hypercellularity with myeloid hyperplasia and slight increase in plasma cells. Elevated levels of serum interleukin-6 (IL-6) and granulocyte colony-stimulating factor (G-CSF) were detected; IL-6 was 62.1 pg/ml and G-CSF was 66 pg/ml, but IL-1 alpha, IL-1 beta and TNF-alpha were within the normal range. Idiopathic plasmacytic lymphadenopathy (IPL) with polyclonal hyperimmunoglobulinemia was diagnosed by lymph-node biopsy and the patient received following treatment with prednisolone and hydroxyurea. Leukocytes, platelets and skin eruptions increased again when the steroid dose was tapered, so we changed treatments to MP (melphalan, prednisolone) therapy. In addition, various neurological abnormalities such as convulsions, loss of consciousness and peripheral polyneuritis were observed. Despite treatment her condition deteriorated and she finally died. Very few reports show these neurological abnormalities in IPL or Castleman's disease therefore we think this is a very rare case.

Focal infections such as chronic tonsillitis or dental caries occasionally play a role in the induction or exacerbation of palmoplantar pustulosis (PPP). Arthro-osteitis is sometimes a complication in severe cases of PPP. To study the effects of bacterial infection on the exacerbation of cutaneous lesions and arthralgia, we investigated the T-cell receptor V beta repertoire in peripheral blood mononuclear cells (PBMC) and tonsil tissue after tonsillectomy in 4 cases, who had chronic tonsillitis and a history of exacerbation of cutaneous lesions following a sore throat. First, serum levels of interleukin-6 (IL-6) and IL-8 were measured before and after tonsillectomy by enzyme-linked immunosorbent assay (ELISA). Second, 3H-TdR incorporation was used to examine the effects of the culture supernatant on the PBMC of the autologous patients, other PPP patients without tonsillitis and normal controls. T-cell receptor V beta repertoire was examined by the reverse transcriptase-polymerase chain reaction method. Results showed that IL-8 was significantly high in the serum and abundantly released from tonsillar lymphocytes, which may play a role in the accumulation of neutrophils in lesional skin. T-cell receptors V beta 6 and 12 were preferentially expressed on tonsillar lymphocytes, and V beta 4, 7, 9, 17 and 18 were detected relatively frequently. These data suggest that restricted usage of T-cell receptor V beta subsets may play a crucial role in the induction of tonsillitis associated with PPP.

We report here a case of neuropsychiatric lupus erythematosus with organic brain syndrome and transverse myelitis which was successfully managed by plasmapheresis. A 27-year-old female with facial rash, arthralgia and fever was diagnosed as having SLE and treated with oral prednisolone (PSL) in June 1996. After 6 weeks she demonstrated muscle pain and a spiking temperature. The dose of PSL was increased but clinical symptoms did not improve. In August, pulse methyl-PSL was performed and she subsequently-developed delirium, impairment of orientation, memory and perception, which were followed by paraplegia of the lower extremities and loss of sphincter control. Intravenous bolus cyclophosphamide was not effective, but liver dysfunction, bone marrow suppression and respiratory failure due to an infection of pneumocystis carinii were observed. We then performed plasmapheresis or immunoabsorption several times. After this treatment steady improvement was observed. High values of antiribosomal P protein antibodies in the serum and interleukin-6 in the cerebrospinal fluid decreased. Small foci of increased signal intensity detected on cranial magnetic resonance imaging and hypoperfused areas on single-photon emission CT diminished. The patient was maintained on low-dose PSL and no recurrence has been observed 15 months from the onset.

A 6-y-old girl with right atrial myxoma presented with remittent fever attacks, general arthralgia and laboratory investigations mimicking rheumatic or autoimmune disease. Interleukin-6 (IL-6) serum concentration was markedly elevated before and normal after tumour resection, whereas myxoma cells stained negatively for IL-6. IL-6 should be considered a myxoma marker: overproduction by myxoma cells and consecutive systemic passage are assumed to cause immunological features.

A 82-year-old woman was admitted because of dehydration and chronic renal failure. Although her renal function was improved by hydration, granulocytopenia (granulocyte number 645/mm3) occurred. Treatment with a relatively high dose of H2 blocker for one month before admission may have caused the granulocytopenia. To prevent possible infection in the patient, we administered 75 g of granulocyte-colony stimulating factor (G-CSF) for 5 consecutive days but 4 days after commencement of administration of G-CSF, pain in both knee joints suddenly appeared. Synovial fluid aspiration revealed granulocytosis (10,400/mm3) and deposition of calcium pyrophosphate dihydrate in the knee joints. The level of G-CSF in the synovial fluid was increased in the joints (700 pg/ml), compared with the serum concentration (62 pg/ml). Furthermore, the concentrations of interleukin-6 and interleukin-8 were markedly increased in the synovial fluid. The results indicated that her pseudogout exacerbation by G-CSF was at least in part explained by the increased production of cytokines in the knee joints. Because the prevalence of pseudogout and gout is overwhelming in the elderly, the possibility of GCSF induced exacerbation of joint pain should be carefully considered in elderly patients.

The aims were to investigate the effect of intravenous infusions of the tumor necrosis factor-alpha (TNF-alpha) antibody infliximab on symptoms and signs of temporomandibular joint (TMJ) involvement in relation to effects on synovial fluid and plasma proinflammatory TNF-alpha, interleukin-1beta (IL-1beta) and interleukin-6 as well as antiinflam matory soluble TNF receptor II (TNF-sRII), interleukin-1 receptor antagonist (IL-1ra), soluble IL-1 receptor II (IL-1sRII) and interleukin-10 (IL-10) in patients with active rheumatoid arthritis (RA). Nineteen patients with TMJ involvement taking methotrexate were included in the study. TMJ and general joint pain intensity as well as pain on mandibular movements, tenderness to digital palpation, pressure pain threshold and maximum mouth-opening capacity were assessed in a clinical examination. The effect of infliximab was assessed after 2 and 14 or 22 weeks. TMJ synovial fluid and venous blood were collected for cytokine analysis at all occasions while determination of erythrocyte sedimentation rate and C-reactive protein were performed at baseline and at long-term follow-up only. Reduction of TMJ pain was associated with raised levels of synovial fluid TNF-sRII and IL-1sRII as well as raised plasma levels of IL-1ra and IL-10. Decreased erythrocyte sedimentation rate was associated with decreased tenderness to digital palpation. Reduced general joint pain intensity was associated with reduced plasma levels of IL-6 and C-reactive protein. In conclusion, systemic treatment with a combination of infliximab and methotrexate reduces TMJ pain in RA in association with an increase in anti-inflammatory cytokines and receptors in synovial fluid and plasma.

Adult-onset Still disease (AOSD) is an uncommon inflammatory condition of unknown origin typically characterized by four main (cardinal) symptoms: spiking fever > or =39 degrees C, arthralgia or arthritis, skin rash and hyperleucocytosis (> or =10,000 cells/mm3) with neutrophils > or =80%. As many other manifestations are possible, diagnosis is potentially challenging. Determination of the total and glycosylated ferritin levels, although not pathognomonic, can help in diagnosis. The disease evolution of AOSD can be monocyclic, polycyclic or chronic. In chronic disease, joint involvement is often predominant and erosions are noted in one-third of patients. No prognostic factors have been identified to date. Therapeutic strategies are from observational data. Corticosteroids are usually the first-line treatment. With inadequate response to corticosteroids, methotrexate appears the best choice to control disease activity and allow for tapering of steroid use. For refractory disease, biological therapy with agents blocking interleukin-1 (anakinra) and then those blocking interleukin-6 (tocilizumab) seem the most promising.

A large range of human viruses are associated with the development of arthritis or arthralgia. Although there are many parallels with autoimmune arthritides, there is little evidence that viral arthritides lead to autoimmune disease. In humans viral arthritides usually last from weeks to months, can be debilitating, and are usually treated with non-steroidal anti-inflammatory drugs, but with variable success. Viral arthritides likely arise from immunopathological inflammatory responses directed at viruses and/or their products residing and/or replicating within joint tissues. Macrophages recruited by monocyte chemoattractant protein-1 (MCP-1/CCL2) and activated by interferon, and proinflammatory mediators like tumour necrosis factor alpha, interferon gamma, interleukin-6 and interleukin-1beta appear to be common elements in this group of diseases. The challenge for new treatments is to target excessive inflammation without compromising anti-viral immunity. Recent evidence from mouse models suggests targeting MCP-1 or complement may emerge as viable new treatment options for viral arthritides.
