Central nervous system (CNS) - related symptoms occur in haemorrhagic fever with renal syndrome (HFRS). To study the CNS and ophthalmic involvement in nephropathia epidemica (NE), the European type of HFRS, we included 26 patients in a prospective study. Most common CNS-related symptoms were headache (96%), insomnia (83%), vertigo (79%), nausea (79%), and vomiting (71%). Ophthalmic symptoms were reported by 82% of patients; 41% had photophobia and 50% had impaired vision. A transient loss of vision was recorded in one patient, who also had a generalized seizure. Minor white matter lesions were found in about half of the patients investigated with brain magnetic resonance imaging (MRI). Electroencephalography (EEG) showed severe alterations in only one patient, and slight and reversible patterns in another two patients. Neopterin, interleukin-6 and interferon-gamma levels in the cerebrospinal fluid (CSF) were elevated, which may indicate immune activation. However, we found no evidence of intrathecal NE virus replication. We conclude that CNS-related symptoms are common in NE, and transient ophthalmic involvement can be demonstrated in about half of the patients.

Interleukin 1 alpha (IL-1 alpha) is a cytokine with pleiotropic effects, including cytotoxic-cytostatic activity against some tumor cell lines. We have conducted a phase I study of recombinant human IL-1 alpha (rhIL-1 alpha) in 17 patients with refractory malignancies to examine its toxicity and biologic activity. rhIL-1 alpha was given as a 2-h IV infusion daily for 5 days at five dose levels (0.08, 0.2, 0.8, 2.0, and 5.0 micrograms/m2). Seventeen patients with malignancies were treated, with no objective tumor responses noted. Common toxicities included: fever (100%), rigors and/or chills (96%), myalgia (54%), and headache (48%). Three patients developed grade III hypotension. The maximum tolerated dose was 2.0 micrograms/m2. rhIL-1 alpha induced a significant increase in absolute neutrophil count over baseline (p < 0.05), a delayed but significant increase in platelet count over baseline (p < 0.05), and there was a marked increase in the number of progenitors [colony-forming units (CFU)-G, CFU-M, CFU-GM, CFU-GEMM and burst-forming units (BFU-E)] observed in the peripheral blood. Nine of 12 evaluable patients showed an increase in bone marrow cellularity or myeloid:erthyroid ratio. Immunophenotyping did not demonstrate an increase in peripheral blood or bone marrow CD34+ cells. Interferon-gamma-mediated monocyte cytotoxicity (MCCTX) was significantly enhanced from baseline (p < 0.001), although an increase in direct MCCTX did not reach statistical significance. In summary, rhIL-1 alpha administration is well tolerated at a dose of 2.0 micrograms/m2 with fever, rigors, myalgia, and headache being the most frequent toxicities. Although there were no objective tumor responses, we have demonstrated significant biologic activity with increased neutrophil and platelet counts, increased peripheral blood progenitor cells, and enhanced interferon-gamma-mediated MCCTX.

A 17-year-old Japanese male was referred with acute urticaria and anaphylaxis after the administration of PL (salicylamide, acetaminophen, anhydrous caffeine and promethazine methylene disalicylate) and Bufferin (aspirin and dialminate) for headache and a high grade fever. The results of prick test, patch test and drug-induced lymphocyte stimulation test with PL and Bufferin were all negative. The patient's peripheral blood mononuclear cells (PBMC) were cultured with or without PL for 72 hours, and the activity of interferon-gamma (IFN-gamma) in the culture supernatant was measured with EIA. A significantly high level of IFN-gamma was detected in PBMC from the patient, but very little in those from healthy control subjects with a history of exposure to PL. This finding may indicate the presence of drug-specific IFN-gamma producing T cells in patients with an anaphylactic shock reaction to medication. Assays that measure the drug-induced IFN-gamma production may thus be a useful diagnostic tool not only for identifying delayed-type hypersensitivity (DTH) to drugs, but also for predicting anaphylactic shock reaction to drugs.

Erythema migrans, the characteristic skin manifestation of acute Lyme borreliosis, is a self-limited lesion. In contrast, acrodermatitis chronica atrophicans, the typical cutaneous manifestation of late Lyme borreliosis, is a chronic skin condition. In an effort to understand pathogenic factors that lead to different outcomes in dermatoborrelioses, skin biopsy samples from 42 patients with erythema migrans and 27 patients with acrodermatitis chronica atrophicans were analyzed for mRNA expression of five pro-inflammatory cytokines (tumor necrosis factor alpha, interleukin-1 beta, interleukin-6, interferon-gamma, and interleukin-2) and two anti-inflammatory cytokines (interleukin-4 and interleukin-10) by in situ hybridization with cytokine-specific riboprobes. Among the 27 patients who had erythema migrans alone with no associated signs or symptoms, the major cytokines expressed in perivascular infiltrates of T cells and macrophages were the pro-inflammatory cytokine interferon-gamma and the anti-inflammatory cytokine interleukin-10. In the 15 erythema migrans patients who had associated signs and symptoms, including headache, elevated temperature, arthralgias, myalgias, or fatigue, a larger number of macrophages and greater expression of macrophage-derived pro-inflammatory cytokines, tumor necrosis factor alpha, interleukin-1 beta, and interleukin-6, were also found. In comparison, infiltrates of T cells and macrophages in the skin lesions of acrodermatitis chronica atrophicans patients had very little or no interferon-gamma expression. Instead, they usually expressed only the pro-inflammatory cytokine tumor necrosis factor alpha and the anti-inflammatory cytokine interleukin-4. Thus, the activation of pro-inflammatory cytokines in erythema migrans lesions, particularly interferon-gamma, seems to be important in the control of the spirochetal infection. In contrast, the restricted pattern of cytokine expression in acrodermatitis chronica atrophicans, including the lack of interferon-gamma, may be less effective in spirochetal killing, resulting in the chronicity of this skin lesion.

In the present study, 23 patients with migraine without aura were monitored during a migraine attack. Plasma levels of interleukin (IL)-4, IL-5, IL-10, and interferon-gamma were measured by enzyme-linked immunosorbent assay techniques. Interestingly, we observed low to undetectable IL-5 and IL-4 levels, whereas high IL-10 levels were seen in 52.2% of the patients. Interferon-gamma plasma levels were undetectable in all patients. After treatment with sumatriptan, 10 patients showed a subsequent decrease in IL-10 and an increase in both IL-4 and IL-5 plasma levels. Although these findings are derived from a limited number of patients, the apparent return to the IL-4 and IL-5 cytokine profile observed during the interictal period leads us to speculate that a preferential enhancement of TH2-type cytokine production may contribute to the pathogenesis of migraine.

In spite of proven immunoregulatory effects in vitro of recombinant human interferon-gamma (rhIFN-gamma) in trauma, clinical trials remain inconclusive in such patients. To investigate the in vivo effect of rhIFN-gamma perioperatively in surgical patients we did a pilot study in 46 patients termed anergic by negative delayed-type hypersensitivity (DTH) skin test, who were undergoing major surgery (22 women and 24 men). They received 100 micrograms of rhIFN-gamma subcutaneously (treated [T]; n = 24) in a double-blind, placebo- (control [C]; n = 22) controlled manner on preoperative days -7, -5, and -3. Whole-blood cultures were stimulated on days -7, -1, 4, 7, and 10 for 12 h with or without LPS (1 microgram/mL). Mild side effects such as fever, headache, or chills were observed in 7/24 patients. No major complications occurred and no significant effect of rhIFN-gamma on HLA-DR, IL-1, and IL-8 was demonstrated. PGE2, TNF-alpha and IL-6 levels were elevated perioperatively in T. versus C. Neopterin, a metabolite of activated monocytes and macrophages, was significantly activated on days -1 (C: 7.6 +/- 1.2 versus T: 20.5 +/- 2.4 nmol/mL; P < 0.001), day 1 (C: 8.3 +/- 1.4 nmol/mL versus T: 24.9 +/- 2.8 nmol/mL; P < 0.001), and day 4 (C: 9.5 +/- 1.1 nmol/mL versus T: 16.0 +/- 1.8 nmol/mL; P < 0.05). Due to the overall lack of infectious complications during the investigation, no clinical effect was shown for rhIFN-gamma treatment. DTH skin testing failed to detect high-risk individuals in the patient population studied. In conclusion, we demonstrated in our pilot study that pre-operative immunomodulation with rhIFN-gamma in surgical anergic patients did not show severe side effects and modulated in vitro immunoresponse. A larger clinical trial in better-defined high-risk patients may show whether a reduction of infectious complications can be achieved.

Yangkyuk-Sanhwa-Tang (YS-Tang), a specific prescription composed of nine herbal mixtures, has been developed as a formula for the Soyangin cerebral infarction (CI) patients according to Sasang constitutional philosophy. However, the mechanisms by which this formula affects CI remain unknown. This study revealed changes in cytokine production in the acute stage of Soyangin constitution CI patients after YS-Tang administration. Clinical signs (vertigo, headache and slurred speech) of CI disappeared significantly in about 2 weeks after oral administration of YS-Tang (P < .05). The mean interleukin (IL)-2 plasma levels were lower by 15% in the patients with CI than in the normal groups, whereas the mean TNF-alpha, IL-4, IL-6 and IgE levels were significantly higher in the patients (P < .01). There were no significant differences in interferon-gamma (IFN-gamma) levels between the groups. Serum IFN-gamma and IL-2 levels were elevated significantly (P < .01) in the patients with CI by YS-Tang administration. Significant reduced plasma levels (P < .01) of TNF-alpha, IL-4, IL-6 and IgE were observed in the patients treated with YS-Tang. During the period of YS-Tang administration, there were no other adverse effects. The data indicate that YS-Tang has an enhancing effect on antiinflammatory cytokines and an inhibitory effect on inflammatory cytokines. These results may implicate a good CI treatment effect of YS-tang and that its action may be due to regulation of cytokine production.

We investigated whether anti-inflammatory effects of treatment with granulocyte colony-stimulating factor (G-CSF, filgrastim) are mediated via prostaglandin E(2) (PGE(2)) induction. In a double-blind crossover study, 10 healthy volunteers received 300 microg of filgrastim or saline 1 week apart. This was repeated after oral administration of 50 mg of flurbiprofen 1 h before injection. The increase in neutrophilic granulocytes initiated by G-CSF was augmented significantly by flurbiprofen. Lipopolysaccharide-induced PGE(2) and thromboxane (TxB(2)) release were increased 8 h after G-CSF treatment. This increase was abrogated by flurbiprofen. However, flurbiprofen did not affect G-CSF-mediated decrease in tumor necrosis factor-alpha or interferon-gamma release. Of the volunteers treated with G-CSF, eight reported side effects (headache and bone pain) against none in the saline group. When flurbiprofen was given before injection, one volunteer each reported side effects in the G-CSF and in the saline group. These data show that G-CSF primes for increased PGE(2) and TxB(2) release. Cyclooxygenase inhibition counteracts neither the hematopoietic nor the anti-inflammatory activity of G-CSF but reduces side effects.

Serial changes in the circulating and cerebrospinal fluid (CSF) cytokine levels were assessed in a patient with Sjogren's syndrome (SS)-associated meningoencephalomyelitis. A 16-yr-old girl diagnosed as having primary SS at 8 yr of age presented headache and vomiting. CSF studies revealed lymphocyte-dominant pleocytosis and high IgM index, but no evidence of infection. Disturbed consciousness and diffuse slow waves on electroencephalogram led to the diagnosis of SS-meningoencephalitis. The clinical condition subsided after a cycle of dexamethasone therapy, however, 2 months later urinary retention and paresthesia of the lower body developed. Craniospinal magnetic resonance imaging (MRI) showed extensive intraparenchymal lesions with high T2-weighted signal intensity adjacent to the posterior left horn of lateral ventricle of the brain and the longitudinal lesion from C5 to T10 of the spinal cord. High-dose methyl-prednisolone and subsequent tacrolimus therapy has effectively controlled the activity of SS-meningoencephalomyelitis. Monitoring of systemic and CSF cytokine levels during the course of illness revealed that CSF interleukin-6, but not interferon-gamma or tumor necrosis factor-alpha levels were the sensitive indicator of disease activity. The unique cytokine profile, differing from those of infectious meningitis may be useful for predicting the central nervous system involvement in autoimmune disease.

Interferon-gamma release assay (IGRA) using specific tuberculous antigens is a rapid, specific and sensitive method for the detection of tuberculous infection, and usually done in peripheral blood sample. We examined IGRA in cerebrospinal fluid (CSF) in a patient strongly suspected of having tuberculous meningitis. A 53-year old woman had a month history of headache and fever with meningeal sign. Routine systemic bacterial, tuberculous and viral analyses all resulted in negative study except for increase of adenosine deaminase in CSF. Neither of antibacterial or antiviral treatments were effective, but she was successfully treated with antituberculous agents. In IGRA, the interferon-gamma concentration in her CSF was high in the background level and increased further after the antigen stimulation, suggesting theoretically that tuberculous antigen-specific T cells were presented in her CSF. IGRA of CSF in combination with peripheral blood-IGRA could be a useful and rapid method for diagnosing active tuberculosis in the central nervous system.
