We wanted to evaluate pain relief and endocrine/immune response after local administration of morphine into an abdominal wound. In a randomised double blind design 29 patients undergoing hysterectomy received two blinded injections of morphine and saline. Before surgery the patients in the control group (n = 15) got 10 mg of subcutaneous morphine into an arm and at skin incision 30 ml of saline was infiltrated directly into the wound. The patients in the wound group (n = 14) received 1 ml of saline into an arm before surgery and 10 mg of morphine in 30 ml of saline into the wound at skin incision. Patient controlled analgesia (PCA) with i.v. morphine was used after surgery. Repeated blood samples were obtained from the day before the surgery until 3 days later and analysed for cortisol and interleukin-6 (IL-6). There were no differences between the groups either in pain relief or in the consumption of PCA morphine. The wound group used 47 +/- 15 mg of i.v. morphine and the control group used 50 +/- 16 mg. Peak values for IL-6 and cortisol appeared at 4 h. The area under the curve (AUC) of cortisol at 0-6, 0-10 and 0-20 h was significantly lower in the control group than in the wound group (P < 0.05). High doses of i.v. morphine reduced cortisol and IL-6 levels in the early hours after surgery. The injection of morphine into the wound did not improve pain relief or reduce the consumption of i.v. morphine after surgery. The endocrine stress response to trauma was modified by preoperative administration of morphine.

A 24-year-old black man presented with diffuse musculoskeletal pain and shotty lymphadenopathy. Laboratory studies revealed hypercalcemia and hyperphosphatemia, very high serum alkaline phosphatase activity, diffuse but intense uptake of radionuclide on a bone scan, urinary N-telopeptide excretion 30 times the upper limit of normal, and serum interleukin-6 100 times the upper limit of normal. An extensive workup for etiologies of the disorder was negative. A bone biopsy revealed intense osteoclastic resorption coupled with rapid bone formation and/or remodeling. This case appears to represent a new entity. Treatment with bisphosphonates produced symptomatic and biochemical improvement.

To study the effect of preoperative treatment with a single high-dose of glucocorticoid on the systemic and immunological response, wound healing, and convalescence after colonic surgery, thirty patients were double-blind randomized to receive either methylprednisolone 30 mg/kg intravenously 90 minutes prior to induction of anaesthesia (group 1, n = 12), or to receive placebo (group 2, n = 12). Six patients were excluded from the study. Assessments of pain, pulmonary function, convalescence, various injury and wound-healing factors were done until 10 days after surgery. Conventional reduction in pulmonary function and mobilization was improved in group 1. Interleukin-6 and C-reactive protein levels increased significantly less in group 1, as delayed-type hypersensitivity was abolished in group 1. Plasma cascade system activation was significantly less pronounced in group 1. Reduction of collagen turnover was observed in group 1, but without detrimental effect on collagen accumulation. It is concluded that treatment with a single high dose of glucocorticoid before colonic surgery may improve postoperative pulmonary function and mobilization and reduce plasma cascade system activations, the inflammatory response, and immunofunction, but without detrimental effects on wound healing.

Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis has been suggested as a model for acute pancreatitis (AP), which allows evaluation of early alterations in the time course of the disease. The influence of the clinical course on procalcitonin (PCT), serum amyloid A (SAA), and several proinflammatory and inhibitory cytokines was evaluated in patients with AP following ERCP. Blood samples were prospectively collected from patients undergoing ERCP. The incidence of ERCP-induced pancreatic damage, defined as abdominal complaints, a threefold increase of serum lipase, and elevation of CRP from <10 to >20 mg/liter was 12.8% (12/94). Only mild clinical courses of acute pancreatitis were observed. PCT significantly increased in subjects with post-ERCP pancreatitis after 24 hr. However, PCT levels did not exceed 0.5 ng/ml in any patient. Interleukin-1 receptor antagonist (IL-1RA) began to differ from baseline 2 hr after ERCP, followed by interleukin-6 (IL-6, 6 hr), solubilized tumor necrosis factor-alpha receptor II (sTNF-alphaRII, 24 hr) and SAA (24 hr). Interleukin 10 (IL-10) showed marked interindividual variations with no obvious peak. Among all parameters evaluated, only peak values of IL-6 and IL-10 showed significant correlations with the reported pain score (r2 = 0.62/0.78), degree of ampullar irritation (r2 = NS/0.87), and the duration of ERCP (r2 = 0.58/0.76). No correlation was found with the volume of the injected contrast agent. We conclude that IL-10 and IL-6 appear to be useful to monitor patients after ERCP. The absence of any PCT elevation in the present study is in accordance with the clinical course of the patients who suffered from mild pancreatic damage without systemic or infectious complications.

Interleukin-6 (IL-6) is a multifunctional cytokine whose actions include modulation of proliferation, differentiation, and maturation of hemapoietic progenitors and other cell lineages; growth regulation of certain carcinoma cell lines; and control of cellular metabolic activities. Initially described in terms of its activities in the immune system and inflammation, accumulating evidence supports an essential role of IL-6 in the development, differentiation, regeneration and degeneration of neurons in the peripheral and central nervous system. We have previously demonstrated that immunoreactive-like IL-6 protein is significantly elevated in the spinal cord in response to peripheral nerve injury that results in neuropathic pain behaviors in the rat. In the current study, our objective was to determine if the source of IL-6 protein was endogenous to the central nervous system by measuring any detectable increases in spinal IL-6 mRNA expression following established mononeuropathy procedures associated with neuropathic pain: spinal nerve cryoneurolysis (SPCN) or spinal nerve tight ligation (SPTL). Using in situ hybridization and a digoxigenin-labeled oligonucleotide, IL-6 mRNA in neurons was significantly elevated at 3 and 7 days post SPCN and 7 days post SPTL in both dorsal and ventral horns. The cellular localization of the IL-6 mRNA expression was predominately neuronal as confirmed by NeuN serial staining. For example, in the SPCN 7 day group, IL-6 mRNA cell profiles in the ipsilateral dorsal horn were significantly different from the normal group (38.7+/-12.8 vs. 4.89+/-1.6, p<0.001). These data demonstrate the central, spinal production of a proinflammatory cytokine in response to a peripheral nerve injury. In addition, these results add to the growing body of literature implicating these immune products, cytokines, as potential neuromodulators/neurotransmitters and provides further evidence for their role in the nociceptive processing which leads to chronic pain.

The aim of this study was to evaluate whether the serum concentration of interleukin-6 (IL-6) reflects disease activity in ankylosing spondylitis (AS). A group of 271 AS patients were enrolled in the study, 261 of whom completed the entire protocol (201 males, 60 females, median age of 53 years). Serum IL-6 was measured three times (I, baseline; II, after 10-12 days; III, after 17-24 days) during a 3- or 4-week treatment at the health resort. At the same times, the variables for mobility were measured, and the patients were asked to assess their complaints (score) in a self-styled questionnaire. The serum concentration of IL-6 correlated with the measurements of occiput-to-wall distance, cervical rotation, finger-floor distance and Schober sign, and with morning pain at all three evaluations. Comparisons between changes in IL-6 and changes in the variables (measures of mobility, scores of the questionnaires) did not reveal significant correlations. Present data would suggest that in AS the serum concentration of IL-6 indicates the degree of mobility restriction resulting from previous disease progression, but is not a reliable marker of current disease activity.

Tight ligation and transection of the L5 spinal nerve (SNL) gives rise to pain which is dependent upon activity in the sympathetic nervous system. It also results in novel adrenergic sympathetic innervation of the dorsal root ganglion (DRG) with the formation of pericellular axonal basket structures around some DRG neurons. Since the sympathetic sprouting and basket formation may represent an anatomical basis for pain-generating interactions between the sympathetic efferent neurons and sensory afferent neurons, it is of great interest to determine possible chemical mediators of this phenomenon. Previous findings have shown that IL-6 can contribute to sympathetically-independent pain, and can give rise to thermal hyperalgesia when injected intrathecally. We have now investigated a possible contributory role of the pleiotropic cytokine interleukin-6 (IL-6) in sympathetically-mediated pain: we gave IL-6 knockout mice and mice of the parent strain c57B6/129 a SNL, assessed their resulting pain behavior for 10 days post-surgery, and used tyrosine-hydroxylase immunohistochemistry to compare sympathetic sprouting in the DRG at the end of the testing period. We found that thermal allodynia (as assessed by measuring the latency to withdrawal from radiant heat) did not differ significantly between strains. On the other hand, in the IL-6 mice, mechanoallodynia (as assessed with von Frey filaments) was markedly delayed. Sympathetic invasion of the fiber tract and cell layer of the DRG, and the formation of pericellular axonal baskets were all significantly reduced in the IL-6 knockout mice compared to the control strain. These results imply a facilitatory role for IL-6 in pain and sympathetic sprouting induced by nerve injury, and add to the growing list of roles for IL-6 in neuropathological events.

We investigated a possible link between galanin expression and evoked pain accompanying painful partial sciatic nerve lesions. Increased galanin immunoreactivity (IR) in the dorsal horn, in gracile nucleus, and in sensory neurons following chronic constriction injury (CCI) compared to complete sciatic transection suggested a facilitatory role in thermal and mechanical hypersensitivity (allodynia). We therefore investigated the effects of endogenous interleukin-6 (IL-6) and nerve growth factor (NGF) on allodynia and neuropeptide expression. IL-6 knockout mice showed decreased allodynia and galanin-IR compared to wild-type mice, but also decreased substance P (SP)-IR in the dorsal horn. Anti-NGF-treated rats with CCI also showed decreased allodynia and SP-IR, but increased galanin-IR in the dorsal horn. These results suggest that evoked pain is more tightly linked to SP than to galanin expression. If galanin's effects are inhibitory as the bulk of the literature suggests, its effects are subordinate to those of SP and to other changes following CCI.

Fibromyalgia is a chronic, painful musculoskeletal disorder characterized by widespread pain, pressure hyperalgesia, morning stiffness and by an increased incidence of depressive symptoms. The etiology, however, has remained elusive. The aim of the present study was to examine the inflammatory response system (IRS) in fibromyalgia. Serum interleukin-6 (IL-6), soluble IL-6 receptor (sIL-6R), sgp130, sIL-1R antagonist (IL-1RA) and sCD8 were determined in 33 healthy volunteers and in 21 fibromyalgia patients, classified according to the American College of Rheumatology criteria. Severity of illness was measured with several pain scales, dolorimetry and the Hamilton Depression Rating Scale (HDRS). Serum sgp130 was significantly higher and serum sCD8 significantly lower in fibromyalgia patients than in healthy volunteers. Serum sIL-6R and sIL-1RA were significantly higher in fibromyalgia patients with an increased HDRS score (> or = 16) than in normal volunteers and fibromyalgia patients with a HDRS score < 16. In fibromyalgia patients, an important part of the variance in sCD8 (50.3%) and IL-1RA (19.3%) could be explained by the HDRS score; 74.3% of the variance in sIL-6R was explained by the combined effects of pain symptoms and the HDRS score; and 25.9% of the variance in serum sgp130 was explained by stiffness. The results support the contention that pain and stiffness in fibromyalgia may be accompanied by a suppression of some aspects of the IRS and that the presence of clinically significant depressive symptoms in fibromyalgia is associated with some signs of IRS activation.

The current prospective randomized study was designed to compare the effects of intracavitary (i.c.) chemotherapy vs immunotherapy vs immunochemotherapy for malignant effusion. Between 1992 and 1995, a total of 42 patients with malignant effusion were registered, and 41 patients were eligible for statistical analysis. The primary diseases of the eligible patients included 27 gastric, four colorectal, four pancreatic, three lung, two liver and one oesophageal cancers. The patients with malignant effusion were randomly assigned into one of three i.c. therapeutic regimens: chemotherapy alone with weekly injection of anticancer agents (ACAs: cisplatin, mitomycin-C, adriamycin, etc.) (Group A, n = 13); immunotherapy alone with weekly injection of streptococcal preparation OK-432 (Group B, n = 14); or immunochemotherapy with ACAs and OK-432 (Group C, n = 14). The response of the effusion, patient survival and the kinetics of cytokines in the effusion were compared. There were no differences in the patients' backgrounds. The side-effects of the regimens included pain, anorexia, fever, leucopenia and anaemia and there were no differences in their incidence among the three groups. One patient died after cisplatin (CDDP) administration in Group A. Cytologic examination revealed that tumour cells in the effusion disappeared in 23% of Group A cases, 36% of Group B cases and 36% of Group C cases. The malignant effusion did not disappear in any of the Group A cases; however, the effusion disappeared in 29% of Group B cases and 43% of Group C cases (P = 0.03, Group A vs Group C). Furthermore, the 50% survival period was 1.6 months for Group A, 2.4 months for Group B and 3.5 months for Group C. The 6-month survival rate was 7% for Group A, 6% for Group B and 34% for Group C, and the 1-year survival rate was 0%, 0% and 17% respectively (P = 0.048, Group A vs Group C by the log-rank test). The analysis of the cytokine kinetics revealed a prominent increase in the level of interleukin-6 in the effusion in Group C. These results suggest that i.c. immunochemotherapy with OK-432 and ACAs may be more beneficial than i.c. chemotherapy alone or immunotherapy alone.
