Recombinant human
IL-4
(rhuIL-4) is primate-specific and produces multiple biologic effects on lymphoid cells involved in protection against cancer. RhuIL-4 was evaluated in the cynomolgus monkey to support clinical studies for the immunotherapy of cancer. Administration of rhuIL-4 to monkeys by SC injection of 0, 0.5, 2.5 or 12.5 micrograms/kg BID for one-month (with two-week recovery) resulted in alterations in clinical chemistry and hematology (CCH) parameters consistent with a consumptive coagulopathy. Histomorphologic evaluation revealed increased granulopoiesis, testicular atrophy, and proliferative and inflammatory vascular lesions (VL). IVL principally affected the arterial tree with some proliferation of medial smooth muscle. During the latter part of the treatment and recovery period. CCH parameters approached or returned to pretreatment values, the former finding attributed to the production of antibody to rhuIL-4. At final necropsy, bone marrow appeared normal, and IVL decreased in incidence and severity. ELISA studies of serum indicated 50-90% of the monkeys developed antibody titers > 1000 by Day 22 (not observed in man). The frequency and severity of adverse effects due to rhuIL-4 in the clinic appear to be does-related and reversible with few objective responses to therapy observed. Common toxicities included milk to moderated fever and
fatigue
and an occasional change in hematopoietic, hepatic and renal function. The monkey predicted hematologic findings, but not all target organ effects.

Interleukin (IL) 2 plays an important role in enhancing the immune response, whereas
IL-4
has pluripotent activities which include affecting immune function. Preclinical data suggest that the combination might have enhanced immunomodulatory activity. In this Phase I trial in patients with advanced solid tumors, both IL-2 and
IL-4
were given by separate s.c. injections simultaneously daily, 5 days in a row, Monday through Friday, for 3 consecutive weeks, followed by a 1-week break from treatment. Cycles could be repeated. The dose of IL-2 was kept constant at 9 x 10(6) IU/m2/injection while the dose of
IL-4
was escalated beginning at 100 microgram/m2/injection and increasing by 100-microgram/m2 increments to a planned level of 400 microgram/m2/injection. Sixteen patients were entered in this study, with one patient being ineligible because of the presence of brain metastases. Of the 15 eligible patients, there were 14 males and 1 female, with a median age of 54 (range, 38-67) years and initial performance status of 0 in 5 patients and 1 in 10 patients. Patients were treated at levels of up to 300 microgram/m2/injection of
IL-4
before the study was closed due to withdrawal of the drug by the manufacturer. The most commonly observed toxicities were
fatigue
, fever and chills, local reaction, nausea/vomiting and anorexia, headache and nasal stuffiness, and coughing, sometimes with the production of clear white sputum, more common in smokers. Duodenal ulcers occurred in one patient and one patient had grade 4 cardiac toxicity consisting of an asymptomatic minimal elevation of the creatinine phosphokinase MB isoenzyme (CPK-MB). Grade 3 hyponatremia occurred in two patients, and elevated liver function tests and creatinine occurred but were not dose limiting. Eosinophilia of unknown significance occurred in all patients. There were statistically significant elevations in absolute numbers of most T-cell subsets examined, without changes in circulating B cells. No antibodies to the
IL-4
were found after one cycle. One patient with renal cell carcinoma showed a significant decrease in tumor burden after one cycle of treatment. Because of the
IL-4
withdrawal, the maximum tolerated dose for this combination of drugs given by the route and schedule used here was not determined and will require additional testing. Subcutaneous IL-2 and
IL-4
given simultaneously show important immunomodulatory and antitumor effects and should be tested further in cancer patients.

The post-Q-fever
fatigue
syndrome (QFS) (inappropriate
fatigue
, myalgia and arthralgia, night sweats, changes in mood and sleep patterns) follows about 20% of laboratory-proven, acute primary Q-fever cases. Cytokine dysregulation resulting from chronic immune stimulation and modulation by persistence of Coxiella burnetii cells or their antigens is hypothesized. We studied cytokine release patterns of peripheral blood mononuclear cells (PBMC) stimulated with various ligands in short-term culture, from 18 patients with active QFS, and 27 controls: six with resolving QFS, five who had had acute primary Q-fever without subsequent QFS, eight healthy Q-fever vaccinees and eight healthy subjects without Q-fever antibody. Conditioned media (CM) from PBMC stimulated in short-term culture with Q-fever antigens, PHA or measles antigen (as an unrelated antigen) were assayed for IL-2,
IL-4
, IL-5, IL-6, IL-10 and IFN gamma by AgEIA, and for IL-1 and TNF alpha/beta by bioassay. Aberrant cytokine release patterns were observed with PBMC from QFS patients when stimulated with Q-fever antigens: an accentuated release of IL-6 which was significantly [p = 0.01, non-parametric one-way analysis of variance (ANOVA)] in excess of medians for all four control groups. With IL-2, the number of responders in the active QFS group was decreased relative to control groups (Fisher's exact test, p = 0.01) whereas the number of IFN gamma responders was increased (Fisher's exact test, p = 0.0008). Significant correlations were observed between concentrations of IL-6 in CM, total symptom scores, and scores for other key symptoms.

It has long been suspected that pentachlorophenol (PCP) exerts a damaging influence on the immune system. In this study, the possible relationship between blood levels of PCP and immune function was studied in 190 patients who had been exposed for more than 6 mo to PCP-containing pesticides. The patients suffered from frequent respiratory infections and general
fatigue
. Lymphocyte subpopulations, in-vitro responses to mitogens, allogeneic stimulator cells, plasma neopterin, cytokines, soluble cytokine receptors, soluble adhesion molecules, and immunoglobulin autoantibodies were determined. A dose-response relationship between blood levels of PCP and cellular and humoral immune parameters was established. Blood levels of PCP were associated negatively with (a) total lymphocyte counts (p = .0002), CD4/CD8 ratios (p = .0015), and absolute counts of CD3+ (p < .0001), CD4+ (p < .0001), CD16+ (p < .0001), CD25+ (p = .0003), DR+ (p < .0001), CD8+/56+ (p = .020), and CD19+ cells (p = .092); (b) plasma levels of interleukin-2 (IL-2) (p < .0001), soluble IL-2R (p < .0001), IL-6 (p < .0001), IL-10 (p = .0039), interferon-gamma (IFN-gamma) (p < .0001), tumor necrosis factor-alpha (TNF-alpha) (p < .0001), transforming-growth factor-beta2 (p = .023), soluble IL-1 receptor antagonist (sIL-1 RA) (p < .0001), soluble intercellular adhesion molecule-1 (p = .0003); and (c) immunoglobulin (Ig) M-anti-Fab type autoantibodies (p = .0353). PCP levels were associated positively with (a) number of impaired stimulation assays per patient (p = .041); (b) number of circulating CD11b+ monocytes (p = .0015); and (c) plasma levels of neopterin (p < .0001),
IL-4
(p = .020), and sIL-6R (p = .020). Compared with patients who had PCP plasma levels that were less than or equal to 10 microg/l, patients with blood levels of PCP that exceeded 10 microg/l experienced the following more often: low numbers of total blood lymphocytes (p = .054), CD3+ (p = .0014), CD4+ (p = .0001), DR+ (p = .0003), CD16+ (p = .0033), and CD25+ cells (p = .0033). In addition, the same aforementioned patients experienced the following more frequently: undetectable plasma levels of IL-2 (p = .0057), IL-6 (p = .042), IL-8 (p = .038), IL-10 (p = .0001), TNF-alpha (p = .0062), and IFN-gamma (p = .016); and impaired in-vitro responses of lymphocytes (p = .071). The authors concluded that increased blood levels of PCP were associated significantly with cellular and humoral immunodeficiencies. Recurrent respiratory infections and general
fatigue
could originate from PCP-associated immunosuppression.

Advanced renal cell carcinoma is a chemoresistant disease. Immunotherapy with alpha interferon or interleukin (IL)-2 has produced response rates of approximately 15%, but better treatments are needed.
IL-4
is a cytokine produced by activated CD4+ lymphocytes and has pluripotent activities including inhibiting the in vitro proliferation of human renal cell carcinoma cell lines. In this trial, patients were required to have a histologic diagnosis of renal cell adenocarcinoma with measurable disease and performance status (SWOG) of 0-1. Patients had to have adequate bone marrow, renal, and hepatic function as well as no clinically significant pulmonary or cardiac dysfunction.
IL-4
was given by subcutaneous injection at a dose of 5 micorg/kg/d, daily for 28 days followed by a 7-day rest period. Fifty-eight patients were registered with seven patients ineligible and two patients not analyzable because they did not receive treatment. In the 49 eligible and analyzable patients, there were no confirmed complete or partial responses. There was one unconfirmed partial response in retro-caval lymph nodes, but no verifying measurement was done. There were seven patients with stable disease, no response, 25 with increasing disease/progression, and 16 patients whose assessment was inadequate to determine response. The median time to progression was 3 months, and the median survival was 13 months. Toxicity was significant with the most common side effects nausea, vomiting, or diarrhea, followed by headache/pain and malaise/
fatigue
/lethargy. There were 13 instances of grade 4 toxicity that occurred in nine different patients. Unique toxicities included Bell's palsy in three patients and hypoglycemia in a previously well-controlled diabetic. Despite promising growth inhibitory and immunologic effects,
IL-4
in this dose and schedule is not useful for the treatment of patients with disseminated renal cell carcinoma.

The aim of the study was to characterise the profile and clinical correlates (arthritis, rash, and
fatigue
) of cytokines, chemokines, and other mediators in symptomatic acute parvovirus B19 infection. Serum was examined from cases of acute B19 infection (as defined by serum anti-B19 IgM positivity) (n = 84), and in normal persons (n = 43) for B19 markers (serum B19 antibodies and DNA), rheumatoid factor (RF), and antinuclear antibody (ANA). A panel of cytokines/chemokines was measured in duplicate using the Bioplex Protein Array system (BioRad Hemel Hempstead, UK). These included interleukin-1 beta (IL-1 beta),
IL-4
, IL-5, IL-6, IL-8, IL-13, tumor necrosis factor-alpha (TNF-alpha), interferon-gamma (IFN-gamma), macrophage chemoattractant protein-1 (MCP-1), granulocyte-monocyte colony stimulating factor (GM-CSF), transforming growth factor-beta1 (TGF-beta 1), endothelin-1 (ET-1), and neopterin. Acute symptomatic infection was characterised by specific IgG positivity (83%), serum B19 DNA positivity (96%), and raised levels of
IL-4
, IL-6, IL-8, TNF-alpha, IFN-gamma, MCP-1, GM-CSF, TGF-beta 1, and ET-1. Patients with acute B19-associated arthritis were found to have lower levels of IL-6, TNF-alpha, and GM-CSF than patients without arthritis, while those with rash had lower levels of TGF-beta 1. It is concluded that cytokine levels following acute symptomatic infection with parvovirus B19 indicate a state of immune activation. The profile of circulating mediators may provide insights into the possible pathogenesis of particular clinical manifestations of this infection.

Gamisipjundaebo-tang (GSDBT) has been used for the purpose of development of physical strength. In the present study, we investigated the immune enhancing effect induced by GSDBT. We investigated the anti-immobility effect of GSDBT via a forced-swimming test and blood biochemical parameters related to
fatigue
, glucose, blood urea nitrogen, lactic dehydrogenase, creatine kinase, and total protein. GSDBT (0.1 and 1 g/kg) was orally administered to mice for 14 days. After 7 and 14 days, as assessed through a forced-swimming test, immobility time was decreased in the GSDBT-administrated group (0.1 and 1 g/kg) in comparison with the control group. In addition, after 8 days, the contents of glucose and lactate dehydrogenase in the blood serum were increased, and contents of blood urea nitrogen were decreased in the GSDBT-administrated group. After 15 days, the contents of glucose were increased, and the contents of lactate dehydrogenase and blood urea nitrogen were decreased in the GSDBT-administrated group. However, it had no effect on the elevation of creatine kinase and total protein level. We also investigated the effect of GSDBT on the production of cytokines in human T-cell line, MOLT-4 cells, and splenocytes. GSDBT significantly increased interferon (IFN)-gamma and interleukin (IL)-2 levels compared with the media control but did not affect
IL-4
. GSDBT increased the protein expression of IFN-gamma in MOLT-4 cells. These results suggest that GSDBT may be useful in immune function improvement and may also have antifatigue properties.

Exercise for individuals with multiple sclerosis (MS) has been shown to improve cardiovascular function, increase strength and endurance, and reduce
fatigue
. The impact of exercise on immune function in the disease, however, remains mostly unexplored. Ten female MS patients participated in an 8 week programme of twice-weekly progressive resistance training, with pre- and post-training assessment of serum concentrations of cytokines IL-2,
IL-4
, IL-6, IL-10, CRP, TNF-alpha and IFN-gamma. After training,
IL-4
, IL-10, CRP and IFN-gamma showed statistically reduced resting concentrations in blood, while TNF-alpha showed non-significant reductions and IL-2 and IL-6 remained unchanged. These results suggest that progressive resistance training may have an impact on cytokine concentrations in individuals with MS and should be confirmed in studies with stronger statistical power. The impact of these changes on overall immune function in MS and on disease status and prognosis remains to be determined.

Lyme borreliosis (LB) can, despite adequate antibiotic treatment, develop into a chronic condition with persisting symptoms such as musculoskeletal pain, subjective alteration of cognition and
fatigue
. The mechanism behind this is unclear, but it has been postulated that an aberrant immunological response might be the cause. In this study we investigated the expression of the T helper 1 (Th1) marker interleukin (IL)-12Rbeta2, the marker for T regulatory cells, forkhead box P3 (FoxP3) and the cytokine profile in patients with a history of chronic LB, subacute LB, previously Borrelia-exposed asymptomatic individuals and healthy controls. Fifty-four individuals (12 chronic LB, 14 subacute LB, 14 asymptomatic individuals and 14 healthy controls) were included in the study and provided a blood sample. Mononuclear cells were separated from the blood and stimulated with antigens. The IL-12Rbeta2 and FoxP3 mRNA expression was analysed with real-time reverse transcription-polymerase chain reaction (RT-PCR). The protein expression of IL-12Rbeta2 on CD3(+), CD4(+), CD8(+) and CD56(+) cells was assessed by flow cytometry. Furthermore, the secretion of interferon (IFN)-gamma,
IL-4
, IL-5, IL-10, IL-12p70 and IL-13 was analysed by enzyme-linked immunospot (ELISPOT) and/or enzyme-linked immunosorbent assay (ELISA). Chronic LB patients displayed a lower expression of Borrelia-specific IL-12Rbeta2 on CD8(+) cells and also a lower number of Borrelia-specific IFN-gamma-secreting cells compared to asymptomatic individuals. Furthermore, chronic LB patients had higher amounts of Borrelia-specific FoxP3 mRNA than healthy controls. We speculate that this may indicate that a strong Th1 response is of importance for a positive outcome of a Borrelia infection. In addition, regulatory T cells might also play a role, by immunosuppression, in the development of chronic LB.

It has been suggested that dysregulation of immune-to-brain communication plays a role in the biopsychological process underlying medically unexplained symptoms (MUS). Immune and non-immune stressors can both be involved in the activation of the central sickness-behavioural-system leading to complaints like malaise, pain and
fatigue
. We hypothesized increased pro-inflammatory and/or reduced anti-inflammatory cytokine activity to exist in MUS patients. Twenty-seven participants (4 male; 23 female) with heterogeneous MUS were compared with 27 healthy controls (6 male; 21 females). Blood samples were analysed for leukocyte subset cell counts, in vitro T-cell mitogen-stimulated cytokine production (IL-2,
IL-4
, IL-5, IL-6, IL-10, TNF-alpha and IFN-gamma) and in vitro monocyte cytokine release (IL-1beta, IL-6, IL-8, IL-10 and TNF-alpha) in response to increasing concentrations of LPS. No significant group differences were found for any of the cytokines measured. One unexpected exception was an elevation in the number of circulating B and NK-cells in participants high on MUS. Nonetheless, no support was found for the hypothesized immunological dysregulation in peripheral blood leukocyte function of MUS patients.
