In patients with cancer, the development of a peripheral neuropathy usually represents a side effect of therapy, the infiltration of nerves or spinal roots by the tumour, or metabolic and nutritional deficits. A neuropathy is defined as paraneoplastic when none of the above causes are detected or when cancer related immunological mechanisms are involved. At least 15% of patients with cancer develop a paraneoplastic sensorimotor neuropathy, which is usually mild and develops during the terminal stage of the disease.1 There is another group of paraneoplastic neuropathies that often precede the diagnosis of the tumour and can be more debilitating than the cancer itself. The diagnosis of these disorders is a challenge for the neurologist, and requires extensive investigations. On pp 7-14 of this issue, Antoine et al 2review their experience with 26 patients whose neuropathy was considered to be paraneoplastic. Most of these patients had severe neuropathies that preceded the diagnosis of the ...

The anti-Hu antibody (HuAb) is directed against RNA-associated neuronal proteins and is known to cause paraneoplastic encephalomyelitis/sensory neuronopathy syndrome mostly when associated with small cell lung cancer (SCLC). Paraneoplastic encephalomyelitis/sensory neuronopathy syndrome with concurrent autonomic neuropathy has been reported to occur in paraneoplastic syndromes, although its occurrence concomitant with acute pandysautonomia is less frequent. The authors describe the clinical, neuropathologic, and serologic features of two cases with an anti-Hu-related paraneoplastic syndrome presenting with progressive autonomic neuropathy. Both patients showed features of dysautonomia, including postural dizziness, abdominal pain, and diarrhea, and symptoms of sensory neuropathy. Investigations disclosed severe sensory and autonomic neuropathy and positive HuAb titers. The disease of patient 1 had a very rapid progression, and the patient died of cardiac arrest within 2 months of the onset of symptoms.

... (or TPE), is a patient treatment during which a large volume of the patients plasma is separated from the cellular components of the blood, removed, and replaced with appropriate fluids. TPE is performed to remove antibodies, immune complexes or other toxic substances circulating in the plasma.. Therapeutic plasma exchange is considered a non-specific therapy since it removes all plasma constituents, not just those causing symptoms.. In order for TPE to be a successful therapy, a disease or disorder must be caused by a disease mediator that can be efficiently removed with the plasma to an extent that reduces symptoms. Many of the diseases for which TPE is considered fall under the specialty areas of renal and metabolic diseases, hematologic diseases and neurologic disorders.. The most common use of TPE is for the treatment of autoimmune or immune mediated diseases or disorders. TPE is used to remove monoclonal immunoglobulins, paraproteins, autoimmune antibodies and ...

Patients usually go to their doctors with neurological complaints and later find they have cancer, a known paraneoplastic syndrome, or neurological problems that suggest a paraneoplastic syndrome. Paraneoplastic syndromes are rare conditions in which the immune system is involved in causing brain damage and fighting cancer.. Such patients with paraneoplastic neurologic degenerations(PNDs) may have autoantibodies, an antibody or protein the immune system creates that is directed against his or her own proteins. This study aims to better understand PNDS by:. ...
A paraneoplastic syndrome is a syndrome (a set of signs and symptoms) that is the consequence of cancer in the body, but unlike mass effect, is not due to the local presence of cancer cells. In contrast, these phenomena are mediated by humoral factors (such as hormones or cytokines) secreted by tumor cells or by an immune response against the tumor. Paraneoplastic syndromes are typical among middle-aged to older patients, and they most commonly present with cancers of the lung, breast, ovaries, or lymphatic system (a lymphoma). Sometimes, the symptoms of paraneoplastic syndromes show before the diagnosis of a malignancy, which has been hypothesized to relate to the disease pathogenesis. In this paradigm, tumor cells express tissue-restricted antigens (e.g., neuronal proteins), triggering an anti-tumor immune response which may be partially or, rarely, completely effective in suppressing tumor growth and symptoms. Patients then come to clinical attention when this tumor immune response breaks ...

Treating a patient with paraneoplastic syndrome goes hand-in-hand with treating the cancer itself, and may include slowing the immune system response thats responsible for the adverse neurological symptoms. A treatment plan must be developed thats appropriate for the particular kind of paraneoplastic syndrome a person has. In combination with chemotherapy drugs to destroy any existing cancer, a physician can prescribe a number of different drugs to limit the tissue damage caused by an overactive immune system. Corticosteroids like prednisone help to lessen inflammation in the body. Unfortunately, some of the potential long-term complications of steroids are diabetes mellitus, osteoporosis, hypertension, and high cholesterol levels, among others. Immunosuppressant drugs like azathioprine and cyclophosphamide help slow down the bodys release of cancer-battling white blood cells, but a negative side effect of these medications is an increased vulnerability to bacterial infections. Based on the ...
Paraneoplastic neurological syndromes (PNS) have frequently been described in patients with lung or breast cancer. However, some reports also described a correlation to carcinoid tumors, probably triggered via the excessive release of hormones. We report the case of a 40-year-old woman that was diagnosed with a neuroendocrine neoplasm (NEN) of the rectum and multiple synchronous liver metastases ten years ago. She initially responded well to transarterial chemoembolization (TACE), resulting in prolonged disease stabilization. However, ten years after initial diagnosis the patient developed unspecific neurological symptoms that could not be classified by standard neurological diagnostic work-up. Special laboratory analysis revealed a high titer of anti-Ri (ANNA-2), a well-characterized antibody that is associated with paraneoplastic neurologic syndromes. The patients symptoms improved markedly after a 5-day-course of high-dose glucocorticoid therapy. To our knowledge, this is the first report of a Ri

Investigators at the French Reference Center on Paraneoplastic Neurological Syndrome (PNS), Lyon Neuroscience Research Center, and other centers in France performed a retrospective study of children and adolescents with anti-Hu antibodies (Hu-Abs) collected by the Reference Center between Jan 1, 2000 and Dec 31, 2011. Of 251 patients with Hu-Abs, 8 were younger than 18 years. All of the 243 adult patients with Hu-Abs had PNS whereas only 2 of 8 (25%) children had neuroblastoma and opsoclonus-myoclonus. The majority (6 children; 5 female, 1 male) presented with limbic encephalitis manifested by progressive personality changes, memory loss, and seizure, and were free of cancer at a mean follow-up of 50 months. Brain MRI scans were abnormal in 4 of 6 patients and CSF showed oligoclonal bands in 4 patients. Treatment with AEDs and immunotherapy was only partially effective, and 5 children were cognitively impaired. The clinical, radiologic, and biological presentations were similar in this series of ...
... are a group of rare degenerative disorders that are triggered by a persons immune system response to a neoplasm, or cancerous tumour. Neurologic paraneoplastic syndromes are believed to occur when cancer-fighting antibodies or white blood cells known as T cells mistakenly attack normal cells in the nervous system. These disorders typically affect middle-aged to older persons and are most common in persons with lung, ovarian, lymphatic, or breast cancer. Neurologic symptoms generally develop over a period of days to weeks and usually occur prior to tumour detection, which can complicate diagnosis. These symptoms may include difficulty in walking and/or swallowing, loss of muscle tone, loss of fine motor coordination, slurred speech, memory loss, vision problems, sleep disturbances, dementia, seizures, sensory loss in the limbs, and vertigo. Neurologic paraneoplastic syndromes include Lambert-Eaton myasthenic syndrome, stiff-person syndrome, encephalomyelitis ...

Paraneoplastic syndromes exist for a number of malignancies and their presentations are diverse. Some of them are self-limited, while others can be life-threatening but regardless of the outcome, understanding the presentation is vital to picking up on the diagnosis for further treatment. The case that is presented here is a rare paraneoplastic skin process called Bazex syndrome that was associated with pancreatic adenocarcinoma.
Therapeutic plasma exchange (TPE) facilitates the unselective removal of pathogenic substances from the patients plasma. Such pathogens include paraproteins, autoantibodies, immune complexes, protein-bound toxins, and mediators of inflammation. During TPE the plasma is separated from cellular blood components by the LIFE 18™ - disk separator. The plasma is discarded and replaced by substitution solutions. Usually, 1-1.5 times the patients plasma volume is exchanged in a session. - Belgique
