A case of anaphylactoid shock occurring immediately after the initiation of second intravenous administration of high-dose immunoglobulin (IVIg) in a patient with Crow-Fukase syndrome]

We report a case of anaphylactoid shock occurring immediately after the initiation of second intravenous administration of high-dose immunoglobulin (IVIg) in a patient with Crow-Fukase syndrome. The patient was a 57-year-old woman, who was admitted to our hospital because of numbness and muscle weakness in the four extremities, difficulty in walking, and foot edema. On admission, her skin was dry and rough, and also showing scattered pigmentation, small hemangiomas, and hypertrichosis in both legs. She had distal dominant muscle weakness, more prominent in her legs, and was not able to walk. Deep tendon reflexes in her four extremities were markedly diminished or absent. She had a glove and stocking type of paresthesia, severe impairment of vibration, and absence of joint position sensation in her four extremities. On laboratory data, serum vascular endothelial growth factor (VEGF) was markedly elevated to 5,184 pg/ml (normal: below 220 pg/ml). Cerebrospinal fluid examination revealed cell counts of 2/microliter and protein level of 114 mg/dl. Abdominal echo showed marked hepatosplenomegaly. On peripheral nerve conduction study, both motor and sensory conduction velocity were undetectable in her legs. We diagnosed her condition as Crow-Fukase syndrome, and started IVIg of polyethyleneglycol-treated gamma-globulin (PEG-glob) at 400 mg/kg/day for 5 consecutive days for polyneuropathy. Since the first IVIg mildly improved muscle weakness, we tried the second IVIg of PEG-glob. However, immediately after the initiation of second IVIg of PEG-glob, she developed hypotention, dyspnea, cold sweating, cyanosis, and became lethargic. We immediately stopped IVIg and started first-aid treatment with epinephrine and corticosteroid for these symptoms. This treatment was successful and the patient fully recovered without any sequelae. Since serum IgE level remained unchanged and lymphocyte stimulation test (LST) was positive against the same rot number of PEG-glob, we diagnosed these symptoms as anaphylactoid shock. Based on the results of LST, we speculated that PEG-glob was the causative agent of anaphylactoid reaction. Anaphylactic or anaphylactoid reaction as adverse effects of IVIg is very rare, and to our knowledge, there are only 4 previous reports of anaphylactic or anaphylactoid reaction caused by IVIg. Therefore, we speculated that the prominent high level of serum VEGF in the present patient might play a significant contributory role in the development of anaphylactoid shock, since the vascular permeability of VEGF is 50,000 times stronger than that of histamine. We consider that it is necessary to carefully monitor IVIg of PEG-glob administration for polyneuropathy in patients with high level of serum VEGF, like Crow-Fukase syndrome.     

A case of Crow-Fukase syndrome associated with idiopathic thrombocytopenic purpura

A 40-year-old man was admitted to our hospital because of paresthesia and weakness of the limbs. At the age of 38, he was diagnosed as having an idiopathic thrombocytopenic purpura (ITP) which have been refractory to oral administration of prednisolone and splenectomy. Platelet-associated IgG was elevated markedly at that time. It was, however, only mildly elevated on this admission. He showed polyneuritis, generalized pigmentation, hirsutism, and marked edema on the legs. The bone X-ray disclosed a lytic lesion in the left iliac bone, which was confirmed as a plasmacytoma by bone biopsy. Axonal degeneration with marked loss of myelinated figure was seen on sural nerve biopsy. Serum immunoelectrophoresis revealed his monoclonal IgG was lambda type. Then, he was diagnosed as having a Crow-Fukase syndrome associated with ITP. Plasma exchange, pulse therapy, and irradiation to plasmacytoma resulted in a slight improvement of the polyneuritis and the skin symptoms, and a disappearance of edema. However, ITP has not responded to these therapies. Although the same autoimmune mechanism is suggested in these conditions, we could not clarify how this monoclonal IgG produce both polyneuritis and ITP.     

A case of granulomatous angiitis of the central nervous system presented with subacute mental deterioration resembling diffuse white matter disease]

We reported a 60-year-old man with granulomatous angiitis of the central nervous system (GACNS) manifesting as subacute mental deterioration. His first symptoms were nausea and vomiting which brought him to a hospital, where no abnormality was found except for gastritis. One month later, he began to feel dizziness and brain tumor was suspected by a neurosurgeon with the MRI findings such as abnormal T2 signal and swelling in his brainstem. While he was followed up, he gradually presented mental change, disorientation and dysmnesia with the abnormal T2 signal spreading over the cerebral white matter bilaterally. Corticosteroid therapy was started based on the suspicion of a lymphoproliferative disease, and his symptoms and the abnormal MRI findings improved. Then he was referred to our department for further evaluation. Because we could not find any evidence of systemic diseases and he had been almost fully recovered, we discontinued the therapy. Soon after that, his mental deterioration as well as the abnormal T2 signal lesions on MRI relapsed. By open brain biopsy, the diagnosis of GACNS was established, and steroid pulse therapy was started. His symptoms and the abnormal T2 signal lesions improved gradually and the steroid was tapered to the maintenance dose without remission. Since the laboratory and imaging findings are not specific for the diagnosis of the angiitis confined to the central nervous system, brain biopsy is recommended for these disorders.     

Vascular endothelial growth factor and Crow-Fukase syndrome]

Serum vascular endothelial growth factor (VEGF) is highly elevated in patients with Crow-Fukase syndrome (CFS) and is well correlated with the clinical manifestations of CFS. In circulating blood, VEGF is specifically stored in platelets and released during platelet aggregation. To clarify the role of VEGF in the pathomechanism of CFS, we transplanted VEGF secretion tumors in nude mice and studied the pathological findings in these mice. Prominent edema with elevated serum VEGF were found. Organomegaly was also found in liver, spleen and kidney. Pathological findings in these organs were similar to those found in autopsies of CFS patients. In peripheral nerve, mild intraneural edema was seen, however, neuropathy was not prominent. These findings suggest that elevated VEGF may be closely correlated with generalized edema (anasarca). However, it is also important to consider factors such as cytokines and other T cell functions that, in association with VEGF, may be the cause of neuropathy in CFS.     

Steroid-responsive diffuse cerebral white matter lesions in a case of intractable fungal meningoencephalitis]

We report a case of fungal meningoencephalitis with steroid-responsive diffuse cerebral white matter lesions. A 49-year-old male developed auditory hallucination, confusion and fever, on April, 1994. He was diagnosed as having cryptococcal meningoencephalitis based on the detection of cryptococcal antigens in the cerebrospinal fluid (CSF). Intravenous administration of fluconazole resulted in improvement of his neurologic symptoms and CSF findings. For the next seven months, he was treated with oral fluconazole and the neurological status was stable. However, soon after the dose of fluconazole was tapered, he became confused and febrile, which made him admitted to our hospital. Neurological examination on admission showed disturbance of consciousness, disorientation and meningeal irritation. The CSF examination revealed mild pleocytosis (mostly lymphocytes), elevated protein and normal glucose levels, although fungus was not detected. The T2-weighted image of brain MRI demonstrated diffuse hyperintense lesions in the bilateral cerebral white matters. GD-DTPA enhanced MRI showed spotty enhanced lesions in the periventricular white matters. The neurologic symptoms were once relieved after intravenous administration of fluconazole was started, but two months later, he became comatose and needed ventilatory support, despite amphotericine B therapy. Then, a needle brain biopsy targeting the white matter lesion was done. Histopathology of the specimen showed chronic inflammation with granuloma formation and T lymphycyte infiltrate around the small vessels, though fungus was not detected in the tissue. Combined therapy with corticosteroid and antifungal agents remarkably improved the neurological symptoms as well as the MRI findings. In the present case, fungal infection possibly induced an altered immune reactions which resulted in the steroid responsive diffuse cerebral white matter lesions.     

A patient with Crow-Fukase syndrome associated with pulmonary plasmacytoma]

We here reported a 54-year-old female patient with Crow-Fukase syndrome associated with pulmonary plasmacytoma. She was found to have scattered tumor in 1990. Although the tumor had slowly grown for the last 10 years, she showed no clinical symptoms. Numbness and weakness of lower extremities began in June 1999, and she was referred to Kyoto University Hospital on Oct. 21 1999 for evaluation of progressive symptoms. She had skin pigmentation, edema of the lower extremities, lymphadenopathy, muscle weakness and sensory disturbance in a glove-and-stocking distribution. Serological examination showed monoclonal IgG-lambda gammopathy. Serum vascular endothelial growth factor (VEGF) was markedly elevated. Microscopic studies on biopsied sural nerve demonstrated mild decrease of myelinated fibers. Immunohistochemically, the pulmonary tumor was defined as an IgG (lambda type) plasmacytoma. After treatment with melphalan-prednisolone therapy, the neurological symptoms improved along with decrease of serum VEGF levels as well as the size of pulmonary plasmacytoma. This is the first report of a patient with Crow-Fukase syndrome associated with pulmonary plasmacytoma. This case suggests that growth of pulmonary plasmacytoma might have played an important role in the overproduction of VEGF and thus development of Crow-Fukase syndrome.     

Multineuropathy in a patient with HBV infection, polyarteritis nodosa and celiac disease

A 53‐year‐old man came to our observation for impaired gait and painful paresthesia in his hands and feet. Three years before he suddenly presented tingling in his hands, followed, after a few months, by paresthesia in his feet, weakness of the right hand and foot and cutaneous erythema. Nearly one year after the onset, he presented left abducens nerve palsy that completely resolved in three months with steroid therapy. The patient's conditions progressively worsened and when he was admitted to our clinic the neurological examination revealed a stepping gait and severe muscular atrophy. Sensory abnormalities involved pin, light touch and vibration perception. In three years he had severe weight loss. Blood test revealed HBV infection and high levels of antibodies to transglutaminase, endomysium, and gliadin. EMG showed sensorimotor asymmetric axonal neuropathy. Nerve biopsy showed fiber loss, axonal degeneration with asymmetrical distribution and focal ischaemia. A duodenal biopsy was consistent with celiac disease. The patient was treated with high dose steroids, plasma exchange, immunoglobulin and lamivudine and began a gluten‐free diet. At discharge he could walk unassisted; sensory abnormalities were greatly reduced. One year later a new duodenal biopsy showed a complete resolution of the pathological abnormalities. Celiac disease, a chronic inflammatory intestinal disease whose pathogenesis involves a HLA DQ2‐DQ8 restricted T‐cell immune‐reaction, can be related to a higher risk of autoimmune disorders, such as insulin‐dependent diabetes or thyroid disease. We report the association of celiac disease, polyarteritis nodosa and HBV infection in a patient who developed a neuropathy and discuss the pathogenetic implications.     

Selektive Immunadsorption bei neurologischen Komplikationen eines systemischen Lupus erythematodes

Vasculitis of the nervous system is a rare cause of multifocal neurologic symptoms and may involve both the central and peripheral nervous systems. Typical symptoms include headache, encephalopathy with cognitive impairment and psychotic symptoms, epileptic seizures, and peripheral neuropathies. Here we report the case of a 71-year-old female presenting with Raynaud's syndrome and paresthesia of the feet. Several weeks later she was admitted to our hospital with a status epilepticus and complex partial seizures. On admission she had mild aphasia, distal paresis of the arms without sensory deficits, and disorientation with hallucinations. Cerebral MRI revealed small, multifocal infarctions in several arterial territories. Multiple cerebral artery stenoses were detected by ultrasound. Examination of the CSF was unremarkable. Serologic tests for autoimmune disorders detected Ro antibodies compatible with systemic lupus erythematosus or Sj?gren's syndrome. A sural nerve biopsy revealed ischemic axonal neuropathy. During administration of i.v. methylprednisolone, the symptom progression stopped but dosages could not be tapered due to severe CNS symptoms (mental decline, disorientation, aphasia, hallucinations). Slow but sustained clinical improvement was achieved by immunoadsorption over 3 weeks followed by a combined high-dose immunosuppressive treatment with cyclophosphamide and prednisolone that paralleled a reduction in anti-Ro titers and normalization of cerebral blood flow velocities as detected by repeated transcranial Doppler sonography. Systemic vasculitis may present with multiple neurologic and psychiatric symptoms due to involvement of the central and peripheral nervous systems. After excluding systemic infection, immunosuppressive therapy should be started early. In our case a combination of high-dose methylprednisolone, immunoadsorption with elimination of Ro antibodies, and cyclophosphamide led to the patient's recovery.     

Chronic multiple paraneoplastic syndromes

A patient presented with symptoms of limbic and brainstem encephalitis, motor and sensory neuronopathy, cerebellar dysfunction, and highly positive anti-Hu antibodies. He also harbored P/Q-type calcium channel antibodies and manifested the Lambert-Eaton myasthenic syndrome (LEMS). Small-cell lung cancer was found, and he received both antineoplastic therapy and intravenous immunoglobulin (IVIg). Remission of the malignancy was achieved. Although the anti-Hu-related manifestations improved after therapy, LEMS has persisted, leading to IVIg dependency.     

Familial amyotrophic lateral sclerosis with rapid progression]

We report a family with autosomal dominant (AD) motor neuron disease. A 41-year-old man developed muscle weakness and fasciculation of the lower extremities. The weakness progressed to the upper extremities and bulbar muscles. The cerebrospinal fluid (CSF) protein level was slightly elevated. A nerve conduction study revealed reduced compound muscle action potentials, but conduction block was not observed. Electromyogram showed acute and chronic neurogenic changes. He was treated with intravenous immunoglobulin (IVIg) and methylprednisolone pulse therapy, but his condition rapidly deteriorated. He developed respiratory failure necessitating artificial ventilation within three months after the onset of the disease. His father developed muscle weakness and atrophy of the upper extremities at age 70, and his cousin developed muscle weakness of the legs at age 41. Their conditions rapidly progressed to quadriplegia. CSF and electrophysiological findings were similar to those of the proband. Treatments by steroid pulse therapy, IVIg, and plasmapheresis were not effective. The father and cousin also required artificial ventilation within 3-4 months from the onset of symptoms, and became locked-in state. Autosomal dominant amyotrophic lateral sclerosis (AD-ALS) was considered, but SOD1 gene mutation was not detected. The present pedigree may have familial ALS caused by a gene mutation other than SOD1.     

A case of neurocysticercosis suggestive of a reinfection, 20 years after the initial onset]

A 70-year-old man, who had frequently visited the Southeast Asian countries as a tour conductor, presented convulsion as an initial symptom twenty years ago. A diagnosis of neurocycticercosis was made by a stereotactic brain biopsy. Thereafter, anticonvulsant therapy was initiated, and he continued his travelling without any troubles. After travelling to Philippines, he suffered high-grade fever and consciousness disturbance, and his general status deteriorated. His consciousness level was evaluated as Japan Coma Scale 3 and his status was bedridden on admission to our hospital in December 1999. Anti-cysticercus cellulosae antibody was clearly detected both in his serum and cerebrospinal fluid (CSF). An MRI brain scan revealed disseminating lesions showing ring enhancement after administration of gadolinium-DTPA both intra and extra brain parenchyma. Steroid therapy and a cysticidal therapy relieved his symptoms, and CSF and MRI findings. Because it may be impossible for the cysticercosis cellulosae to be latent in the central nervous system as long as 20 years and to be reactivated, the reinfection of cysticercus cellulosae was supposed to be the cause of his symptoms.     

Intramedullary tuberculoma mimicking primary CNS lymphoma

The incidence of primary central nervous system lymphoma (PCNSL) has been on the rise in the setting of immunodeficiency syndromes such as acquired immune deficiency syndrome (AIDS). Its diagnosis has been facilitated by the advent of a cerebrospinal fluid (CSF) Epstein-Barr virus (EBV) PCR assay. The reported high sensitivity and specificity of this assay has made it the cornerstone of diagnosis of PCNSL, replacing more traditional methods such as an open CNS biopsy. Here, we have described a patient with a known history of C3 AIDS presenting with lower extremity weakness and eventual myelopathy who was later diagnosed as having intramedullary PCNSL after detection of EBV DNA in his CSF. After failing to respond to radiotherapy, he underwent a spinal cord biopsy revealing intramedullary tuberculoma. This case illustrates the risk of misdiagnosis with this assay and the importance of histological confirmation of a pathological lesion prior to implementation of therapy.     

A patient with neuroborreliosis presenting gadolinium-enhanced MRI lesions in bilateral facial nerves]

We report a 33-year-old man with bilateral facial paralysis due to neuroborreliosis. About three weeks after rhinorrhea and fever lasting four days, he noticed fatigue in the legs and paresthesia in all four extremities. Another week later, he developed paresthesia in his tongue and bilateral facial muscle weakness, and was admitted to our hospital. On admission, neurological examination revealed moderate bilateral facial muscle weakness, mild paresthesia in the tongue and four extremities, and decreased Achilles tendon reflex bilaterally. Mild pleocytosis and increased protein were found in the cerebrospinal fluid (CSF). IgM antibodies that reacted with the antigens of Borrelia garinii and Borrelia afzelii were found in his serum. Clinically and serologically, he was thus diagnosed as having neuroborreliosis. Brain MRI revealed gadolinium-enhanced lesions of the bilateral facial nerves in the facial nerve canal portion. After three weeks of treatment with 100 mg/day doxycycline and 2 g/day ceftriaxone sodium, his symptoms and CSF abnormalities were rapidly improved. Although facial nerve paralysis is a major symptom of neuroborreliosis, the present report is the first to detect the inflammatory lesions of the facial nerves in the facial nerve canal portion by MRI.     

Spinal cord involvement revealing systemic sarcoidosis

Spinal neurosarcoidosis is rare (0.43 p. 100 of all sarcoidosis) and can be the initial manifestation of the disease. A 43-year-old right handed African man developed a progressive dorsal neck pain, slowly worsened paresthesia weakness in the legs and a gait disturbance. Magnetic resonance imaging (MRI) scan of the cervical and thoracic spinal cord (sagittal T(1)- weighted image) revealed diffuse enlargement of the cord from C2 to T7 with intense intramedullary enhancement from C2 to T3 after administration of contrast material on sagittal T(1)- weighted image. Cranial MRI scan was normal. Radiographs of the chest revealed bilateral symmetric hilar mediastinal lymphadenopathy with no pulmonary infiltrates. Bronchial biopsy demonstrated non caseating granulomas with langerhans giant cells. The serum angiotensin converting enzyme level was elevated. The patient received corticosteroid with good progressive response. His neurologic symptoms improved markedly and twenty months post-treatment MRI showed no abnormality on enhanced T(1)- weighted images. Two years later he had no relapse. Only 6 to 10 p. 100 of patients with neurosarcoidosis have spinal cord involvement, which may account for the first clinical manifestation of the disease. Most patients with neurosarcoidosis have associated extraneurologic abnormalities. The diagnosis is supported usually by extraneurologic biopsies. Spinal cord biopsy needs to be considered on case-by-case basis.     

Highly concentrated vascular endothelial growth factor in platelets in Crow-Fukase syndrome

We report a marked difference in concentration of vascular endothelial growth factor (VEGF) between serum and plasma in patients with Crow-Fukase syndrome (CFS). The serum/plasma VEGF levels in 4 CFS patients were 8,634/152, 5,203/176, 3,724/127, and 868/13 pg/ml, respectively. We also showed that platelets were a major source of this VEGF and that VEGF was released during platelet aggregation by physiological stimulation. It is suggested that in CFS, local VEGF concentration is markedly elevated by aggregation of platelets containing excessive VEGF and their adhesion to vascular walls, resulting in excessive physiological activities of VEGF. Our findings provide important information for developing more effective therapeutic trials.     

Superior vena cava syndrome and compression neuropathy of the right brachial plexus following cardiac pacemaker implantation]

We reported a case with the superior vena cava syndrome and compression neuropathy of the right brachial plexus after pacemaker implantation. A 27-year-old man with the second degree atrio-ventricular block had underwent pacemaker implantation via the right subclavian vein at the age of 19. Since the age of 25, he occasionally experienced paresthesia and swelling in his right arm after excessive work. These symptoms gradually resolved within a few days by rest. On June 2, 1990, he noticed swelling and paresthesia of his right face, arm and upper trunk after excessive labor. A few days later, weakness of right hand developed. On examination on June 8, the right arm was edematous, but not cyanotic. There were weakness and hypoactive muscle stretch responses in the right upper extremity with hypesthesia of all modalities in the neck, arm and upper trunk of the right side. Venous angiography showed total occlusion of the right brachiocephalic vein and superior vena cava and well-developed collateral channels. We speculate that swelling of the right upper extremity, which became overt when arterial blood supply to that limb outbalanced impaired venous drainage, finally compressed the right brachial plexus.     

Relapsing Guillain Barré Syndrome and nephrotic syndrome secondary to focal segmental glomerulosclerosis

A 49-year-old man developed simultaneously a Guillain Barré Syndrome (GBS) and a nephrotic syndrome (NS). The patient relapsed twice, despite treatment with intravenous immunoglobulins (IVIg) after a full or partial recovery, and became resistant to IVIg. Renal biopsy revealed focal segmental glomerulosclerosis (FSGS). He responded to plasmapheresis and corticosteroids with simultaneous recovery of his GBS and NS, suggesting a common pathogenesis of the two conditions.     

Delayed neuropsychiatric sequelae after acute hydrogen sulfide poisoning: affection of motor function, memory, vision and hearing

A shipyard worker was poisoned by hydrogen sulfide (H2S), and rescued after 15-20 min. He regained consciousness after 2 days. Three days later his condition deteriorated, and he was more or less comatose for a month. When he woke up, he was amnesic, nearly blind, had reduced hearing, and had a moderate spastic tetraparesis and ataxia. Two months after the accident, he had greatly improved. Audiograms showed hearing loss with maximum at 2000 Hz and significantly poorer speech discrimination. EEG showed generalized dysrhythmia. At follow-up 5 years later he had not been able to resume his work, and had slight motor, memory and visual symptoms. CT and MRI showed slight cerebral atrophy. EEG and evoked responses were normal.     

An autopsy case of Degos disease with neurological symptoms--neuropathological observations and increased platelet aggregation]

We reported clinical and neuropathological observations of a 41-year-old man with Degos disease. He first noted painless skin lesions over the upper extremities in January, 1982. Three years later he was diagnosed as Degos disease by skin biopsy, and treatment with aspirin was started. In September, 1985, he complained of paresthesia on his right arm, followed by a series of new neurological manifestations suggesting multifocal spinal cord lesions. On October 28, examination of admission showed papules with central umblication over the whole body except the head, face, palms, soles and scrotum. Neurological examination revealed no weakness, diminished right biceps reflex, exaggerated patellar reflexes and Achilles reflexes, left extensor plantar reflex, hypesthesia and hypalgesia to the level of Th8, mild left spastic gait, and retention of urine. In November, he had paraparesis, loss of vibration sense of lower extremities, hypesthesia and hypalgesia to the level of TH4, and weakness of right upper extremity. In December, he showed tetraplegia, left-sided facial palsy, and hypesthesia and hypalgesia to the level of C5. In January, 1986, he showed right facial palsy, left facial hypesthesia, pseudobulbar palsy. In February, he had bilateral abducens nerve palsy and hiccups. On February 18, he died of intracranial hemorrhages. He had episodic abdominal pain several times during admission. His condition deteriorated progressively in four months after the first manifestation of neurological symptoms, despite the therapy with heparin, urokinase, ticlopidine, dipyridamole, and prednisolone. Laboratory studies showed gradual increase of CSF proteins (from 156 mg/dl to 602 mg/dl) and extremely increased platelet aggregation.(ABSTRACT TRUNCATED AT 250 WORDS)     

White matter alteration in a patient with Graves' disease

A case of Graves' disease with white matter abnormalities is presented here. The diagnosis as Graves' disease was made when the patient was 5 years old, and a subtotal thyroidectomy was performed when she was 10. Her neurological symptoms began at age 19 with paresthesia of her legs and lower body. Cranial magnetic resonance imaging was normal; thoracic magnetic resonance imaging revealed demyelinating lesions. Intravenous pulse steroid therapy improved her symptoms. Ten months later she described dizziness, lower body paresthesia, and ataxia. Both her cranial and thoracic magnetic resonance imagings revealed demyelinating lesions. After pulse steroid therapy, glatiramer acetate therapy was initiated with diagnosis of an autoimmune multiphasic demyelinating syndrome. Five months later, she presented with right-sided mild optic neuritis followed by rapid spontaneous remission. Antithyroglobulin antibody levels remained normal; antithyroid peroxidase antibody level was high. This presents a rare case of Graves' disease associated with multiphasic demyelinating autoimmune syndrome.
