A 44-year-old woman with Marie-Bamberger's syndrome and diabetes insipidus had a lung tumour with mediastinal metastases, but no signs of metastases to the hypothalamus or pituitary gland. A week after removal of the tumour, the joint pain, polyuria and polydipsia disappeared. The tumour was diagnosed histopathologically as a moderately differentiated adenocarcinoma with focal neuroendocrine cell differentiation and dispersed cells reacting with antisera against neurone-specific enolase, S-100 protein, neuropeptide Y, follicle-stimulating hormone, substance P, vasoactive polypeptide (VIP), adrenocorticotropic hormone and pancreatic polypeptide (PP) as well as to one of three tested antisera raised against antidiuretic hormone (ADH). It was suggested that Marie-Bamberger's syndrome might be caused by one of these immunoreactive substances or by a substance that shares an amino acid sequence with one of these neuroendocrine peptides. It was also suggested that the tumour might produce an ADH-like substance which might have an ADH-antagonist effect.

A 73-year-old man with acute adult T-cell leukemia (ATL) in remission was re-admitted to our hospital due to drowsiness, headache, and bilateral knee joint pain on May 17, 1998. On admission, examinations revealed decreased serum sodium concentration (112 mEq/l), low plasma osmotic pressure (259 mOsm/l), and elevated antidiuretic hormone(5.6 pg/ml). Cerebrospinal fluid examination showed an increased number of abnormal flower-like lymphocyte (951/microliter). Brain computed tomography and magnetic resonance imaging found no abnormality in the hypothalamus or pituitary gland. These findings yielded a diagnosis of syndrome of inappropriate antidiuretic hormone secretion (SIADH). Though ATL patients typically exhibit a variety of clinical symptoms, SIADH is rarely one of the complications. Further investigation showed that IL-1 beta and IL-6 concentrations were increased in spinal fluid but not in serum. Recently, it has been reported that exogeneous IL-6 is an inducer of ADH secretion, and that primary ATL cells and HTLV-I infected cell lines can produce IL-6. In this case, we speculated that IL-6 produced by ATL cells that infiltrated a cerebral lesion may have played an important role in the development of SIADH.

Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is a rare complication of adult Still's disease (ASD). We experienced a male ASD patient who complained of arthralgia and intermittent fever. Chest radiograph and pleural fluid analysis revealed pleurisy with effusion. We diagnosed this patient with SIADH and confirmed the disappearance of hyponatremia and pleurisy after starting treatment with nonsteroidal anti-inflammatory drugs. In this study, we reviewed previous literature and the case of our ASD patient with hyponatremia. This reported case is the fourth case of SIADH in an ASD patient. Further, we found that hyponatremia is a relatively common complication of ASD, and pleurisy has a possibility to develop SIADH in patients with ASD.

Neuroplastic changes in the amygdala account for emotional-affective aspects of pain and involve neuropeptides such as calcitonin gene-related peptide and corticotropin-releasing factor. Another neuropeptide system, central arginine vasopressin, has been implicated in neuropsychiatric disorders, but its role in pain-related emotional expression and neuroplasticity remains to be determined. Here, we tested the hypothesis that arginine vasopressin in the amygdala contributes to pain-related emotional-affective responses, using stereotaxic applications of arginine vasopressin and antagonists for G-protein coupled vasopressin V1A and oxytocin receptors in adult male Sprague-Dawley rats. In normal animals, arginine vasopressin increased audible and ultrasonic vocalizations and anxiety-like behavior (decreased open-arm preference in the elevated plus maze). The facilitatory effects were blocked by a selective V1A antagonist (SR 49059, Relcovaptan) but not by an oxytocin receptor antagonist (L-371,257). L-371,257 had some facilitatory effects on vocalizations. Arginine vasopressin had no effect in arthritic rats (kaolin/carrageenan knee joint pain model). SR 49059 inhibited vocalizations and anxiety-like behavior (elevated plus maze) in arthritic, but not normal, rats and conveyed anxiolytic properties to arginine vasopressin. Arginine vasopressin, SR 49059, and L-371,257 had no significant effects on spinal reflexes. We interpret the data to suggest that arginine vasopressin through V1A in the amygdala contributes to emotional-affective aspects of pain (arthritis model), whereas oxytocin receptors may mediate some inhibitory effects of the vasopressin system.

Interleukin-6 (IL-6) is implicated in the pathogenesis of both systemic juvenile idiopathic arthritis (SJIA) and syndrome of inappropriate secretion of antidiuretic hormone (SIADH), but the 2 have not been previously described as occurring together. We report a case of a 6-year-old girl with symptoms of arthralgia, daily fevers, evanescent rash, lymphadenopathy, and laboratory evaluation showing elevated inflammatory markers, consistent with SJIA. At presentation, the patient had hyponatremia with a sodium level of 128 mEq/L. She had low serum osmolality with elevated urine osmolality, consistent with SIADH. Hyponatremia improved temporarily during times of fluid restriction as expected in SIADH, but did not resolve until SJIA was treated successfully with tocilizumab, an IL-6 receptor antibody that inhibits IL-6 activity. The positive response to treatment with tocilizumab supports the role of IL-6 in the pathogenesis of both SJIA and SIADH. Patients with SJIA should be monitored for SIADH to avoid complications of untreated hyponatremia.

Osteoarthritis (OA) causes chronic joint pain and significantly impacts daily activities. Hence, developing novel treatment options for OA has become an increasingly important area of research. Recently, studies have reported that exogenous, as well as endogenous, hypothalamic-neurohypophysial hormones, oxytocin (OXT) and arginine-vasopressin (AVP), significantly contribute to nociception modulation. Moreover, the parvocellular OXT neurone (parvOXT) extends its projection to the superficial spinal dorsal horn, where it controls the transmission of nociceptive signals. Meanwhile, AVP produced in the magnocellular AVP neurone (magnAVP) is released into the systemic circulation where it contributes to pain management at peripheral sites. The parvocellular AVP neurone (parvAVP), as well as corticotrophin-releasing hormone (CRH), suppresses inflammation via activation of the hypothalamic-pituitary adrenal (HPA) axis. Previously, we confirmed that the OXT/AVP system is activated in rat models of pain. However, the roles of endogenous hypothalamic-neurohypophysial hormones in OA have not yet been characterised. In the present study, we investigated whether the OXT/AVP system is activated in a knee OA rat model. Our results show that putative parvOXT is activated and the amount of OXT-monomeric red fluorescent protein 1 positive granules in the ipsilateral superficial spinal dorsal horn increases in the knee OA rat. Furthermore, both magnAVP and parvAVP are activated, concurrent with HPA axis activation, predominantly modulated by AVP, and not CRH. The OXT/AVP system in OA rats was similar to that in systemic inflammation models, including adjuvant arthritis; however, magnocellular OXT neurones (magnOXT) were not activated in OA. Hence, localised chronic pain conditions, such as knee OA, activate the OXT/AVP system without impacting magnOXT.
