In a double-blind, placebo-controlled study, the non-steroidal anti-inflammatory drug, piroxicam, in combination with alfentanil given in a patient-controlled analgesia system, was compared with alfentanil alone given by the same route for analgesic effect, side effects and acute phase reaction over a 4-day period following anterior cruciate ligament reconstruction of the knee. The patients receiving piroxicam had lower pain scores and consumed less alfentanil. There were no differences with regard to side effects between the two treatment groups, apart from significantly more sedation at 08.00 h on the first postoperative day in the non-piroxicam group. Piroxicam did not influence either the levels of interleukin-6 or the acute phase response to surgery.

We report a patient with metastatic adenocarcinoma of the lung who had a detectable serum interleukin-6 (IL-6) level. Despite systemic chemotherapy, the tumor progressed, with elevation of serum IL-6 level. Palliative steroid therapy with 20 mg/day of prednisolone resulted in the decline of serum IL-6 level and, simultaneously, improved anorexia and oral intake. Although there was no weight gain or improvement in hypoalbuminemia, these results suggest that steroids may suppress the abnormal production of IL-6 in cancer patients and that this action affects symptoms. Further study is warranted to clarify the role of IL-6 in tumor-related symptoms and the effect of steroid therapy in relation to IL-6 production in cancer patients.

Inhalation of O3 causes airways neutrophilic inflammation accompanied by other changes including increased levels of cyclo-oxygenase products of arachidonic acid in bronchoalveolar lavage fluid (BALF). Ozone O3 exposure also causes decreased forced vital capacity (FVC) and forced expiratory volume after 1 s (FEV(1)), associated with cough and substernal pain on inspiration, and small increases in specific airway resistance (SRAW). The spirometric decrements are substantially blunted by pretreatment with indomethacin. Since the O3-induced decrement in FVC is due to involuntary inhibition of inspiration, a role for stimulation of nociceptive respiratory tract afferents has been suggested and cyclo-oxygenase products have been hypothesized to mediate this stimulation. However, the relation (if any) between the O3-induced neutrophilic airways inflammation and decreased inspiratory capacity remains unclear. We studied the effects of pharmacologic inhibition of O3-induced spirometric changes on the inflammatory changes. Each of ten healthy men was exposed twice (5-week interval) to 0.4 ppm O3 for 2 h, including 1 h of intermittent exercise (ventilation 601*min(-1)). One-and-a-half hours prior to and midway during each exposure the subject ingested 800 mg and 200 mg, respectively, of the non-steroidal anti-inflammatory drug ibuprofen (IBU), or placebo [PLA (sucrose)], in randomized, double-blind fashion. Spirometry and body plethysmography were performed prior to drug administration, and before and after O3 exposure. Immediately following postexposure testing, fiberoptic bronchoscopy with bronchoalveolar lavage (BAL) was performed. Neither IBU nor PLA administration changed pre-exposure lung function. O3 exposure (with PLA) caused a significant 17 percent mean decrement in FEV(1) (P <0.01) and a 56 percent increase in mean SRAW. Following IBU pretreatment, O3 exposure induced a significantly lesser mean decrement in FEV(1) (7 percent) but still a 50 percent increase in mean SRAW. IBU pretreatment significantly decreased post-O3 BAL levels of prostaglandin E2 (PGE2) by 60.4 percent (P <0.05) and thromboxane B(2) (TxB(2)) by 25.5 percent (P <0.05). Of the proteins, only interleukin-6 was significantly reduced (45 percent, P <0.05) by IBU as compared to PLA pretreatment. As expected, O3 exposure produced neutrophilia in BALF. There was, however, no effect of IBU on this finding. None of the major cell types in the BALF differed significantly between pretreatments. We found no association between post-exposure changes of BALF components and pulmonary function decrements. We conclude that IBU causes significant inhibition of O3-induced increases in respiratory tract PGE(2) and TxB(2) levels concomitant with a blunting of the spirometric response. This is consistent with the hypothesis that the products of AA metabolism mediate inhibition of inspiration. However, IBU did not alter the modest SRAW response to O3.

It has been suggested that neuroimmunologic mechanisms may be involved in the development and maintenance of neuropathic pain. To further address this concept, the immunoreactive spinal expression of the pro-inflammatory cytokine, interleukin-6 (IL-6), was determined in the mononeuropathy model in the rat, sciatic cryoneurolysis (SCN). This well-established animal model expresses behaviors suggestive of neuropathic pain in humans. Immunohistochemical localization in the spinal cord was determined at 3, 7, 14, 21, 35, and 120 days after SCN (n = 6 per time point). Immunoreactive IL-6 increased incrementally in the substantia gelatinosa and motoneurons over time following SCN as compared with normal rats. In an additional study, recombinant human IL-6 was administered intrathecally to normal and previously SCN-lesioned rats. Intrathecal IL-6 produced touch-evoked allodynia (increased sensitivity to a nonnoxious stimulus) in normal rats and thermal hyperalgesia (increased sensitivity to a noxious stimulus) in previously lesioned SCN rats. These results provide evidence that IL-6 may be involved in the cascade of events leading to the development and maintenance of behaviors suggestive of neuropathic pain following peripheral nerve injury.

Hypertension and norepinephrine hypersecretion in a 59-year-old woman suffering from malignant pheochromocytoma with multiple metastases were appropriately controlled with alpha- and beta- blockers, and alpha-methyltyrosine (alpha-MT), a catecholamine-synthesis inhibitor. Metastasized vertebrae were treated with external radiation to relieve pain, but this treatment had to be interrupted at a total dose of 20 Gy because the patient suffered acutely exacerbated hypertension (200/110 mmHg), tachycardia (160 beats/min) and a low-grade fever. Simultaneously her serum levels of LDH, potassium, urea nitrogen, creatinine, white blood cell count, CRP and norepinephrine were significantly increased, suggesting that this episode was due to radiation-induced tissue destruction and the leakage of catecholamines and possibly interleukin-6, a cytokine mediating inflammation which is reportedly present in pheochromocytoma. The marked hypertension was controlled by continuous i.v. administration of phentolamine and propranolol. Although radiation therapy effectively relieves pain due to neoplasmic metastasis to the bone, physicians should be aware that life-threatening complications such as the above occur in malignant pheochromocytoma. Sufficient pretreatment with adrenergic blocking agents and/or alpha-MT and careful monitoring of the patient's general condition during radiation therapy, even at a low dose, are highly recommended.

In patients with right iliac fossa (RIF) pain it can be difficult to distinguish between appendicitis and nonspecific abdominal pain (NSAP). In this study we sought to determine whether serum interleukin-6 (IL-6) levels, an early marker of acute inflammation, taken at the time of admission could predict the outcome of patients admitted with RIF pain. Data were collected in a prospective manner on 53 consecutive patients (23 male, 30 female), mean age 22.1 years (range 10-79 years). Nineteen (36%) patients underwent surgery, of whom 16 had appendicitis (histologically proven). The mean (SEM) IL-6 levels (pg/ml) in patients undergoing operation vs those receiving non-operative management were 270.8 (106.3) vs 265.0 (80.4) (P = NS). The mean white blood cell (WBC) counts (x10(9)/l) in these patients were 14.28 (0.81) vs 9.66 (0.67), respectively (P = 0.0002). When patients with a confirmed diagnosis of appendicitis were compared with patients with a diagnosis of NSAP, the IL-6 levels were 149.4 (69.1) vs 363.6 (113.2), respectively (P = NS). In the same groups of patients, the WBC counts were 14.21 (0.81) vs 9.51 (0.68) (P = 0.004). We conclude that IL-6 levels taken at the time of admission are not useful in predicting the outcome of RIF pain.

The magnitude of the inflammatory response to surgery depends on the degree of injury during surgical procedures. Laparoscopic techniques are generally associated with less postoperative pain and shorter hospital stay compared with open procedures, presumably due to less tissue injury and reduced inflammatory response. However, no study has been done, to our knowledge, to assess the inflammatory response to surgical trauma following laparoscopic assisted vaginal hysterectomy. We have, therefore, compared the magnitude of the inflammatory response to injury after laparoscopically assisted vaginal hysterectomy (11 patients) and abdominal hysterectomy (11 patients) by measuring serum C-reactive protein (CRP) and interleukin-6 (IL-6) on admission, and at 24 and 48 hours after the operation. Postoperatively, serum CRP rose significantly in both groups but levels in patients who underwent laparoscopically assisted vaginal hysterectomy were significantly lower than in those who underwent abdominal hysterectomy. Serum IL-6 rose significantly after abdominal hysterectomy but not after laparoscopically assisted vaginal hysterectomy. Our results show that the inflammatory response to surgical trauma was significantly less after laparoscopically assisted vaginal hysterectomy than after abdominal hysterectomy confirming that the laparoscopic procedure causes less tissue damage than the abdominal procedure.

A rare case of dedifferentiated liposarcoma (well-differentiated liposarcoma with an inflammatory malignant fibrous histiocytoma (MFH)-like anaplastic component) occurring in a 69-year-old male is presented. The patient had noticed a dull pain in his left loin and thigh for about 1 month. Computed tomography examination revealed a low-density mass lesion, measuring about 6 cm in diameter, in the left iliopsoas muscle, and it was surgically removed. Grossly, the lesion was composed of an encapsulated, soft, whitish mass and an adjacent, well-demarcated, yellowish hard nodule, measuring about 2.5 cm in diameter. Microscopically, both lesions showed features of an inflammatory variant of MFH and a sclerosing type of well-differentiated liposarcoma, respectively. To our knowledge, only two cases of dedifferentiated liposarcoma combined with inflammatory MFH as a dedifferentiated component have been recorded in the literature. The salient feature of the present case is a systemic inflammatory reaction, as shown by prominent leukocytosis (up to 73,900/mm3) and the elevated serum value of C reactive protein (up to 26.0 mg/dL), which were transiently reduced after surgery. The inflammatory reaction was suggested to be induced by cytokines, such as granulocyte colony-stimulating factor and interleukin-6, which were probably produced by the tumor cells in the present case, because the elevated serum values of those cytokines were decreased after surgery.

The cutaneous nociceptive response threshold to mechanical and thermal stimulation, the development of hyperalgesia and plasma extravasation after subcutaneous injection of carrageenan and the development of autotomy behaviour after nerve section were assessed in interleukin-6-deficient (IL-6-/-) and age-matched wild-type (IL-6+/+) mice. IL-6-/- mice had significantly lower response threshold to both mechanical and thermal stimulation in comparison to IL-6+/+ controls. Both IL-6-/- and IL-6+/+ mice developed hyperalgesia to mechanical and thermal stimulation after localized carrageenan injection, but the magnitude of the hyperalgesia was less in the IL-6-/- than in the IL-6+/+ controls. IL-6-/- mice also exhibited less plasma extravasation after carrageenan injection. No difference was noted between males and females in basal nociception and inflammatory hyperalgesia. However, female IL-6-/- mice exhibited autotomy behaviour, a sign of neuropathic pain, significantly more frequently and after a shorter interval following peripheral nerve injury than male IL-6-/- or male and female IL-6+/+ mice. It is suggested that IL-6-/- mice exhibited numerous changes in nociceptive responses compared to controls, some of which are sex related. The mechanisms of these changes in relation to null-mutation of the IL-6 gene and the influence of genetic background are discussed. 1997 Academic Press Limited.

Patients suffering from persisting sciatic pain 8 weeks following discectomy were compared with patients displaying low complaints and healthy, pain-free volunteers regarding their interleukin-6 (IL-6) levels, morning cortisol levels and degree of psychological distress. Whereas serum concentrations of IL-6 were measured by collecting blood samples between 0945 and 2400 h in intervals of 45 min, morning cortisol levels were obtained by sampling saliva on five ensuing measurements, beginning immediately after awakening. In addition, questionnaires aimed at measuring depressive mood, somatic symptoms, coping and chronic stress were filled out by the subjects. The patients with ongoing pain displayed significantly elevated IL-6 levels and an attenuated elevation of cortisol secretion after awakening compared to the two other groups. Patients with persisting pain were also suffering more frequently from depressive mood and ongoing work-related strains. In addition, maladaptive coping strategies were favoured by these patients. The presented data support the hypothesis that the persistence of pain in many of the concerned patients may significantly be related to dysfunctional reciprocal relations between neural, endocrine and immune function.
