The syndromes could also be called autoimmune synaptic encephalopathies and their prototype is NMDAR encephalitis. Here the symptoms are not due to antigen-complement transmitted damage, but rather due to the alteration of synaptic structure or function.

While the symptoms are severe they are treatable and reversible. Among the molecules of the cell surface we find receptors, ion channels and secreted proteins which are responsible for transsynaptic complex organization. The phenomenon of antigen modulation is reversible and the symptoms may prostate specific antigen blood test mayo clinic after removal of prostate specific antigen blood test mayo clinic antibodies.

Psychosis, acoustic hallucinations, confusion, amnesia, aphasia, and epileptic seizures may appear in the early stages, and then in weeks is followed by involuntary dyskinesia, autonomic instability, hypoventilation, and disorders of consciousness. The involuntary movements are usually choreoathetotic but some patients develop mutism or catatonia. Sometimes contrast enhancement is observed on the cortical meninxes or in the basal ganglia.

In later stages mediotemporal or frontotemporal atrophy may appear. Usually, the titer of the NMDAR antibody is higher in the serum than in the liquor, though it is still present in the liquor even after normalization of the level in the serum, which indicates antibody synthesis occurs intrathecally. The NMDA receptor plays an important role in synaptic signal transduction and plasticity. The receptor has NR1 subunits which bind glycin and NR2 subunits which bind glutamate.

Antibodies are produced against the extracellular NR1 subunits and a reversible reduction of NMDAR expression occurs; complement mediated structural damage has not been proven. The reduction of NMDAR secondarily leads to the inactivation of GABAergic neurons which is likely behind the orofacial dyskinesias caused by dysinhibition of the brainstem and basal ganglia.

An asymptomatic condition after a spontaneous recovery is rare. Immunotherapy is effective if it is started in the early stage. The outcome in paraneoplastic cases is more successful if the tumor is removed during the first 4 months. The first choice is a steroid, plasma exchange and IVIG treatment which may be combined. Second line treatment is cyclophosphamide and rituximab treatment and then azathioprine can be used for the purpose of chronic immunosuppression.

Symptoms start to improve in a few days after starting treatment although complete recovery takes months. Animation 3. The final product is a large transynaptic protein complex that includes the presynaptic Kv1 potassium and postsynaptic AMPA receptor whereby it controls synaptic signal transduction. Contactin-2 also has a large extracellular domain together with CASPR2 forms a link between axon and glial membranes.

The onset of the clinical picture is usually acute or subacute. Memory loss, confusion, mediotemporal epileptic seizures, agitation and psychiatric symptoms develop over a few days to a week. Sometimes a previous infection can be identified.

The serum concentration of antibodies against the VGKC complex is usually high and rarely is paraneoplastic in origin. A PET examination can be more sensitive in detecting hippocampal dysfunction and might show altered glucose metabolism in the temporal lobe. Electroencephalography usually shows interictal foci of epileptiform activity or slowing over anterotemporal or midtemporal regions and ictal activity in the same areas.

Seizures often show a poor response to antiepileptic drugs, but react well to immunotherapy. Faciobrachial dystonic seizure FBDS Antibodies to the VGKC complex are also present in the case of epilepsy associated with this anticonvulsive drug resistant movement disorder.

Hyperkinesias occur mainly in face and upper limbs and correspond to dystonia. Immunotherapy is effective, but if treatment is started late, typical limbic encephalitis may develop. Morvan syndrome The clinical picture is characterized by the triplet of neuromyotonia, myasthenia, and thymoma.

These symptoms are frequently accompanied by insomnia, psychiatric disorders, memory loss, confusion, and an alteration of neuroendocrine control. Cases with thymoma have a worse prognosis. Limbic encephalitis associated with antibodies against the AMPA receptor The clinical picture is the same as for limbic encephalitis and frequently there are relapses.

Psychosis can be the initial and dominant symptom. The antibodies are produced against subunits of the ionotropic glutamate receptor which mediates the significant part of excitatory neurotransmission in the brain.

Usually it responds well to tumor removal and immunotherapy. Limbic encephalitis associated with antibody to GABAB receptor The GABA receptor is built from 2 subunits; its function is to suppress potassium channels, to reduce the frequency of presynaptic firing and to inhibit excessive synchronization.

Half of the patients are male and the average age is Encephalitis associated with antibodies against the glycine receptor This is a rare syndrome, which is a progressive encephalomyelitis characterized by rigidity and myocloni PERM. The leading symptom is rigidity. A stimulus triggered startle reaction is characteristic; the presence of an eye movement disorder is a sign of brain stem involvement.

Respiratory insufficiency appears late in the course and is life threatening. The antibody a-GAD characterizing stiff person syndrome is not detectable but the GlyR 1 antibody might be present. It may associate with thymoma; a full recovery is expected after thymoma removal and immunotherapy.

Paraneoplastic encephalomyelitis PEM This syndrome is characterized by multifocal symptoms affecting the central nervous system; limbic, cerebellar, brain stem and spinal cord symptoms combine.

It frequently associates with sensory and autonomic symptoms because the dorsal root ganglion might be damaged. Severe neurological symptoms stabilize after the initial progression which lasts for weeks to months. The limbic and cerebellar symptoms are identical with the symptoms of syndromes that occur independently; isolated brain stem encephalitis is rare. Gastrointestinal symptoms, pseudoobstruction, and autonomic symptoms like orthostatic hypotension, cardiac arrhythmia, erectile dysfunction, urinary retention and the dysfunction of perspiration may also be present.

Subacute sensory neuropathy Several neuropathies might occur as a part of paraneoplastic disease. SSN, which develops due to the inflammation of the dorsal root ganglion, is the most characteristic.

Usually it is asymmetric and starts with a lancinating pain, burning dysaesthesia, numbness, and sensitivity to cold. It generally starts in the proximal part of the upper limbs, then progresses over weeks to months; all nerves including trunk, peripheral nerves of stomach and cranial nerves get damaged.

Because of the loss of deep sensation a limb, then trunk and gait ataxia is typical, therefore the patient becomes bedridden. Alterations of taste, hearing loss and facial numbness may develop due to the involvement of the cranial nerves.

Electroneurography shows axonal damage affecting sensory nerves, including the amplitude reduction of compound muscle action potential, while the conduction velocity of motor neurons remain in a normal range. In the liquor, protein level elevation and pleocytosis is frequently detected, and sometimes OCB is present. A nerve biopsy can help to distinguish SSN from vasculitis associated mononeuritis multiplex, but it is rarely necessary.

Different tumors can express the antibody like small cell lung cancer, neuroblastoma, sarcoma and prostate carcinoma.

The Hu antigen plays a role in neural differentiation, maturation, and maintenance of neuronal phenotype. Anti-Hu is polyclonal; its titer is higher in the liquor than in the serum.

From: Botulinum Toxin, The prostate normally measures 3 cm in length height4 cm in width transverseand 2 cm in depth anteroposterior dimension. It remains relatively stable in size until the age of 50 when increasing weight of the gland is observed.

In this case the prognosis of cancer is worse indicating the role of the antibody in the anti-tumor reaction. Antibodies to CRMP5 can be detected in Prostate specific antigen blood test mayo clinic in prostate specific antigen blood test mayo clinic of small cell lung cancer and thymoma; in prosztata karbantartása cases dementia, chorea and optic neuropathy may appear as well. In some SSN cases associated with stiff person syndrome antibodies against amphiphysin were verified.

When anti-Ma2 is present, symptoms of limbic, hypothalamic or brain stem encephalitis appear as well, which may occur in cases of testicular tumor, non-small cell lung cancer, breast, parotid and colon carcinomas. The prognosis is not good. We can try immunomodulating or immunosuppressive treatment.

Even though plasma exchange reduces the level of antibodies, the neuronal destruction already present at the beginning of treatment is generally irreversible. Paraneoplastic opsoclonus-myoclonus syndrome POM It usually characterized by the acute appearance of involuntary, chaotic, continuous, conjugate, arrhythmic, multidirectional, and large amplitude saccades of the eyes which increase upon fixation and closing of the eyes, and which not disappear even when the patient is asleep.

The pathological eye movements are accompanied by cerebellar symptoms like limb and trunk ataxia as well as myocloni. The symptoms can be explained by the destruction of the Purkinje cells of the cerebellum, lesions of the dentate nucleus and demyelination of the cerebellar white matter.

The brain MRI is usually normal, but a moderately elevated protein level or pleocytosis might be present in the liquor. Antibodies are not detectable in most of the patients. Steroid treatment improves the paraneoplastic cases but idiopathic POM in adults does not react to immunotherapy. Nystagmus and oscillopsia may be reduced with the Milyen fű a prosztatitisből of antiepileptic drugs, baclofen or propranolol treatment, whereas prostate specific antigen blood test mayo clinic myoclonus improves with antiepileptic therapy only.

Lambert-Eaton myasthenic syndrome LEMS This syndrome is a disorder of the neuromuscular junction, of paraneoplastic or autoimmune origin, in which the release of acetylcholine in presynaptic motor nerve-endings is inhibited due to the disturbance of calcium inflow.

Presynaptic depolarization is inhibited; therefore the concentration of acetylcholine decreases in the neuromuscular junction. LEMS is usually a disorder of the middle aged without a sexual predominance.

Increased exhaustibility precedes muscle weakness and then the proximal muscles of the lower limbs start to weaken. In contrast with myasthenia where weakness increases after repeated, short muscle contractions, in the case of LEMS, a temporary increase of muscle strength develops.

Ptosis and double vision is less frequent and milder than in myasthenia. Sometimes it is associates with autonomic symptoms like dryness of the eyes and mouth, blurred vision, impotence, constipation, sweating, and orthostatic hypotension.

It is less frequent in cases of carcinoid, prostate carcinoma, thymoma, and non-Hodgkin lymphoma. There have also been examples of association of with other autoimmune diseases, as well, like Hashimoto-thyreoiditis, celiac disease, vitiligo and diabetes. To increase muscle strength, a 3,4- diaminopyridine which is potentiated by pyridostigmin is suggested, beside the chemotherapy against the tumor. Steroids, plasma exchange or IVIG, and azathioprine treatment can be tried if symptoms do not improve.

The most frequent tumor type in females is the ovarian and breast, while lung and gastrointestinal malignancies are more frequent in males.

Dermatomyositis is characterized by symmetric, mainly proximal tetraparesis which develops over weeks or months. CK elevation and dermatological symptoms can appear. The characteristic dermatological sings are periorbital symmetric erythema, oedema of upper eyelid, blue-purplish pigmentation and Gottron papules which are usually located on the metacarpophalangeal region. Tumor screening is the first step, and after its treatment steroid, IVIG, and azathioprine treatment can be given.

The non-classical paraneoplastic syndromes The non-classical syndromes frequently occur without a tumor in the background. Focal encephalitides Brainstem encephalitis may damage the medulla; vomiting, vertigo, nystagmus, ataxia, and bulbar symptoms may appear. In the case of damage of the rostral mesencephalon, eye movement disorders and extrapyramidal symptoms like tremor, rigor, dystonia and myocloni can occur.

Acute necrotizing myelopathy An ascending paraplegia appears initially and the sphincters get paralyzed; furthermore it is characterized by thoracal, segmental sensory loss.

Paraneoplastic retinopathy It is characterized by sensitivity to light, ring shaped scotomas and concentric loss of the visual field. Usually this is bilateral but the fluctuation of the caliber of retinal arteries is asymmetric. Antibodies against recoverin which is a calcium binding protein of photoreceptors are detected. Usually it associates with small cell lung cancer and melanoma and may moderately improve with steroid treatment. Stiff person syndrome 9.

Classic stiff person syndrome The clinical picture is characterized by rigidity of the abdominal and paraspinal muscles. The painful muscle cramps appear upon sensory stimulation.

Sometimes the proximal muscles of lower limbs are affected and a spastic gait develops. Rigidity ceases during sleep. The diagnosis is based on continuous muscle activity of the paraspinal muscles on EMG screening, which decrease with diazepam administration. Protein elevation or OCB may be present in the liquor. GAD is an intracellular antigen that appears in the inhibitory neurons of the myelon and in the ß cells of the pancreas.

Dysfunction of the descending, tone controlling reticulospinal tract is thought to be the reason for the increased muscle tone. Stiff person plus syndromes Rigidity affects distal muscle groups as well, and other accompanying symptoms are present. Paraneoplastic etiology is rather characteristic in cases associated with encephalomyelitis.

In encephalomyelitis with rigidity, small cell lung cancer, thymoma, breast or colon carcinoma may be in the background. Jerking stiff person syndrome is characterized by the appearance of myoclonus. Stiff limb syndrome features painful spasms developing in distal muscle of the lower limbs. Motoneuron disorders Amyotrophic lateralsclerosis, progressive muscular atrophy and progressive bulbar paralysis belong to the motoneuron disorders.

The destruction of anterior horn motoneurons is rarely paraneoplastic in nature, rather lymphoma or multiple myeloma are in the background, while damage of upper motoneurons occurs with small cell lung cancer or breast carcinoma. Peripheral neuropathies Subacute sensory neuropathy is the most frequent form but other clinical pictures may appear as well. Sensory motor neuropathy is characterized by prostate specific antigen blood test mayo clinic and motor axonal damage in cases of small cell lung cancer, breast carcinoma or melanoma.
