Cytokine-release syndrome is a symptom complex associated with the use of many monoclonal antibodies. Commonly referred to as an infusion reaction, it results from the release of cytokines from cells targeted by the antibody as well as immune effector cells recruited to the area. When cytokines are released into the circulation, systemic symptoms such as fever, nausea, chills, hypotension, tachycardia, asthenia,
headache
, rash, scratchy throat, and dyspnea can result. In most patients, the symptoms are mild to moderate in severity and are managed easily. However, some patients may experience severe, life-threatening reactions that result from massive release of cytokines. Severe reactions occur more commonly during the first infusion in patients with hematologic malignancies who have not received prior chemotherapy; severe reactions are marked by their rapid onset and the acuity of associated symptoms. Massive
cytokine
release is an oncologic emergency, and special precautions must be taken to prevent life-threatening complications. This article will present an overview of the etiology and management of
cytokine
-release syndrome in patients receiving monoclonal antibodies to better prepare oncology nurses to safely care for such patients.

AMD3100 given with G-CSF has been shown to mobilize CD34+ cells in non-Hodgkin's lymphoma (NHL), multiple myeloma (MM), and Hodgkin's disease (HD) patients who could not collect sufficient cells for autologous transplant following other mobilization regimens. These poor mobilizers are usually excluded from company-sponsored trials, but have been included in an AMD3100 Single Patient Use protocol, referred to as a Compassionate Use Protocol (CUP). A cohort of 115 data-audited poor mobilizers in CUP was assessed, with the objective being to collect > or =2 x 10(6) CD34+ cells per kg following AMD3100 plus G-CSF mobilization. The rates of successful CD34+ cell collection were similar for patients who previously failed chemotherapy mobilization or
cytokine
-only mobilization: NHL -- 60.3%, MM -- 71.4% and HD -- 76.5%. Following transplant, median times to neutrophil and PLT engraftment were 11 days and 18 days, respectively. Engraftment was durable. There were no drug-related serious adverse events. Of the adverse events considered related to AMD3100, two (1.6%) were severe (one patient --
headache
, one patient -- nightmares). Other AMD3100-related adverse events were mild (84.8%) or moderate (13.6%). The most common AMD3100-related adverse events were gastrointestinal reactions, injection site reactions and paresthesias. AMD3100 plus G-CSF offers a new treatment to collect CD34+ cells for autologous transplant from poor mobilizers, with a high success rate.

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.

Since the effectiveness of high dose intravenous immunoglobulin (IVIg) was first demonstrated in autoimmune thrombocytopenia, IVIg has been investigated in the treatment of various autoimmune rheumatic disorders. Controlled randomised studies have established the efficacy of IVIg in Kawasaki's syndrome, for which combined IVIg and aspirin (acetylsalicylic acid) now constitutes the standard treatment. Another controlled study has demonstrated the benefit of IVIg in dermatomyositis. IVIg treatment in juvenile rheumatoid arthritis has produced contradictory results. Uncontrolled studies and case reports on the application of IVIg in systemic lupus erythematosus, ANCA-associated vasculitides and adult rheumatoid arthritis generally describe short term positive effects. Various mechanisms are thought to underlie the effect of IVIg on autoimmune rheumatic diseases, such as: blockade of Fc receptors;immunomodulation via anti-idiotypic interactions;inhibition of complement-mediated tissue damage;modulation of
cytokine
expression by leucocytes and endothelial cells; andinhibition of superantigen-mediated T cell activation. IVIg is considered to be a low-risk form of treatment. Reported adverse effects include
headache
, aseptic meningitis and transient impairment of renal function. Haemolysis and anaphylactic reactions are rare. The effect profile of IVIg makes it a relevant, although still experimental, form of treatment in autoimmune rheumatic disorders, but its high cost renders it unsuitable as a first-line treatment. Because IVIg does not weaken patients' resistance to infection, it might serve as a therapeutic option in bridging clinical situations where immunosuppressive or cytotoxic approaches are contraindicated in patients with autoimmune disorders, such as intercurrent infection or in the period immediately before and after surgery.

We describe a rare case of clinically mild, influenza-associated encephalopathy with a reversible splenial lesion. A 12-year-old Japanese girl presented with fever and
headache
, followed by muscle weakness and somnolence. Magnetic resonance imaging on day 4 of her illness showed a solitary lesion of the splenium of the corpus callosum that was most prominently visualized on diffusion-weighted images. The patient was diagnosed with influenza B-associated encephalopathy. Her neurologic signs had completely recovered by day 6, and the splenial abnormalities disappeared on day 11. A review of the literature identified four additional pediatric cases of this type of influenza-associated encephalopathy: three and one were caused by influenza A and B viruses, respectively. Common features include prompt and complete recovery from clinical and radiologic abnormalities, a relatively older age (> or = 5 years), and a higher incidence among the Japanese. To better understand the pathophysiology of this encephalopathy, we examined interleukin-6, tumor necrosis factor-alpha, and soluble tumor necrosis factor receptor 1 levels in serum and cerebrospinal fluid from this patient. The results did not reveal any elevations of these cytokines in the sera or cerebrospinal fluid, suggesting that this condition is not mediated by augmented
cytokine
responses.

An increasing number of papers deal with immunological factors in
headache
syndromes such as migraine and cluster
headache
. The aim of this review is to give an overview of the factors that have been measured and to assess their reliability and relevance for the pathogenesis of these
headaches
. Most of the studies are handicapped by methodological problems, especially the different classifications of
headaches
, the lack of adequate controls and methodological problems with the measurement of certain immune parameters. Nevertheless, immunological abnormalities have been shown to be reproducible. These are the increased number of autoantibodies in migraine and the augmented number of deficient NK cells and monocytes in cluster
headache
. Furthermore, some
cytokine
levels (IL-2) have been shown to be decreased in migraine and tension-type
headache
, while others (IL-1, TNFalpha) seem to be elevated. Cluster headache seems to be associated with persisting viral infections. Studies of immunoglobulins and immuncomplex levels and analyses of immunomediators such as prostaglandins and histamine still yield contradictory results. Although the immunological changes have been shown to be valid, their pathogenesis in these
headaches
is unclear. With the increasing recognition of the existence of a neuroimmunologic network, alterations in each system should always be considered to be associated with changes in an other. Acute or chronic pain seems to trigger immunological abnormalities.

Intraventricular meningiomas are infrequent intracranial tumors. Clinical symptoms are mainly due to an increased intracranial pressure or a direct pressure on the surrounding brain structures. Inflammatory syndrome was described in some patients with chordoid meningiomas. Here we report a case of right intraventricular clear cell meningioma in a 50-year-old man who presented with fever,
headache
, and inflammatory syndrome. Clinical and biological normalization was rapidly obtained after tumor removal. Immunohistochemical examination showed tumor cells and lymphocytes positivity for the pyrogenic
cytokine
interleukin-6, with a same intensity. To our knowledge, this is the first case described in the literature concerning an adult man with an intraventricular clear cell meningioma associated with a systemic inflammatory syndrome.

Fibromyalgia (FMS), a predominantly female (85%) syndrome, affects an estimated 2% of the US population with skeletal muscle ache, fatigue,
headache
, and sleep disorder. The pathogenesis of FMS is unknown and there is no laboratory test for diagnosis. In this study, plasma levels of 25 cytokines and chemokines in 92 female patients with FMS and 69 family members were measured compared to 77 controls. Trans-endothelial migration of normal leukocytes in response to FMS plasma and the
cytokine
profile of human myoblasts were analyzed. High levels of MCP-1 (P<0.001) and eotaxin (P<0.01) were found in patients and family members compared to controls. Patients (56/92) treated with the single agent guaifenesin (>3 months) had higher levels of eotaxin than those not treated (P<0.01). Diluted plasma from patients increased the migration of normal eosinophils and monocytes, but not neutrophils, through an endothelial/Matrigel barrier only when mast cells are included in the lower wells (P<0.05). Furthermore, myoblasts can secrete MCP-1, eotaxin, and IP-10, while treatment with MCP-1 caused secretion of IL-1beta, eotaxin and IP-10. FMS is associated with inflammatory chemokines, that MCP-1 and eotaxin may contribute to the symptoms of FMS, and that similar
cytokine
profiles found in family members support the idea that FMS has a genetic component. Furthermore, the chemokine profile associated with FMS has direct effects on the migration of eosinophils and monocytes in the presence of mast cells, and skeletal muscle itself may secrete.

Fibromyalgia syndrome (FMS) is now understood as a chronic pain syndrome, and recent evidence indicates it is not a pure psychosomatic disorder. We review the current knowledge in FMS pain pathways, focusing on the central system sensitization phenomenon and the abnormalities in the inhibitory pain systems. Chronic
headache
is one of the most common symptoms in FMS, and better knowledge of their common pathophysiologic features can help us understand both conditions better. These features include the nerve growth factor actions and failure of the endocannabinoid system. In addition, we review new immunological aspects of FMS, both in their humoral (autoantibodies, antipolymer antibodies) and
cytokine
(interleukin-2) aspects.

Peripheral neuropathies of identical etiology can be painful or painless. The reason for this difference in clinical presentation is as yet unknown; however, immune mediators, particularly cytokines, may play a role. Cytokines are proteins that are produced by immune and nonimmune cells and are categorized as pro- and anti-inflammatory. The role of cytokines in the induction and maintenance of pain has been well established in animal models. Proinflammatory cytokines are mostly algesic, whereas anti-inflammatory cytokines have analgesic properties. Clinical research also gives evidence for the involvement of cytokines in painful and painless neuropathies. A proinflammatory
cytokine
profile seems to be associated with pain in peripheral neuropathies of different etiologies and in other painful disorders such as the complex regional pain syndrome. Specifically, an imbalance between pro- and anti-inflammatory cytokines may contribute to pain generation. A better understanding of the underlying pathophysiology may open new opportunities for the treatment of pain.
