In 1975, during the largest epidemic of St Louis encephalitis (SLE) in the United States, 416 cases were diagnosed in Ohio. Persons who were admitted to two Columbus (Ohio) hospitals with suspected acute viral CNS infection were prospectively studied to define the virologic and clinical aspects of SLE. Sixteen cases of SLE were diagnosed serologically. Fifteen patients had signs of encephalitis and one had aseptic meningitis. Six patients had the syndrome of inappropriate antidiuretic hormone secretion. Other frequent findings included moderate peripheral leukocytosis and CSF pleocytosis, with mild elevation of CSF protein levels but normal glucose levels. Severe neurologic sequelae were infrequent. The EEG proved valuable in diagnosis and prognosis. Results of brain scans were normal. Virus in CSF or urine was not demonstrated, nor was viral antigen in CSF or urine sediments. Specific antibody was found in the sera and CSF of all patients who were tested, but interferon was not detected.

A 38-year-old physician developed polyuria and hypodipsia four days after the onset of an upper respiratory tract infection. Subsequent investigation showed a concentration defect with dehydration that partially corrected with vasopressin injection (Pitressin) administration compatible with partial central diabetes insipidus (DI). Skull roentgenograms, EEG, and lumbar puncture were normal. The polyuria and hypodipsia slowly resolved without treatment. Normal urinary concentration ability was achieved by the 48th day, but a residual elevation in serum osmolarity persisted for one year. Review of the literature failed to show previous documentation of transient DI with elevated serum osmolarity from an acute, febrile illness. The mechanism is speculative, but may be related to a subclinical encephalitis. The true frequency of this syndrome and its relationship to the frequent observation of transient polydipsia and polyuria in "benign" febrile illness remains to be determined.

Nineteen children aged four months to 15 years with diabetes insipidus (DI) secondary to severe brain insults were studied. The main primary brain insult was severe head injury in 12, anoxic ischemic brain damage in four, encephalitis in two, Reye's syndrome in one. Sixteen children died, and three survived. The time from insult to onset of polyuria varied from several hours to one month, and was significantly shorter in head trauma patients, 1.8 +/- 0.9 vs. 9.3 +/- 1.9 days for patients with anoxic ischemic brain damage (p less than 0.03). Twelve of the 19 patients met the criteria for brain death at onset of DI. Treatment by appropriate fluids and vasopressin resulted in resolution of polyuria and increase in urine osmolality. Ten patients developed DI while being treated with dopamine for hemodynamic support. In two of these patients, the cessation of dopamine was time-related to the resolution of DI. Our results indicate that as many as 15% of children with DI (with 95% confidence) following severe brain injury may survive. Hence, despite the overall poor prognosis, its occurrence does not necessarily indicate brain death.

6 patients with amyotrophic lateral sclerosis were treated with intravenous infusion of 100-200 million IU per day of human leukocyte interferon. Side effects of treatment included fever, chills, malaise, nausea, marked leukopenia, mild anemia, and thrombocytopenia. Tiredness, confusion, papilledema, and overall signs of acute encephalitis were observed. Tendon reflexes and muscle force decreased. EEG activity was slowed, and evoked potentials showed significant slowing of conduction times. Neuropsychological tests revealed congitive dysfunction. The syndrome of inappropriate antidiuretic hormone secretion developed in all patients. All side effects were reversible with cessation of interferon treatment.

The medical records of 31 immunocompromised patients who experienced varicella infections from 1975 to 1982 were reviewed. Fifteen of these patients had visceral involvement. In these 15 patients, two clinical patterns of progression were noted: (1) Eleven patients with life-threatening involvement experienced hepatitis (n = 11), pneumonitis (n = 11), abdominal pain (n = 11), encephalopathy (n = 10), coagulopathy (n = 10), inappropriate antidiuretic hormone (ADH) syndrome (n = 10), back pain or myalgia (n = 5), and myocarditis (n = 1). Seven of these patients survived, all without sequelae. (2) Four patients with a milder course experienced subclinical hepatitis (n = 4), mild pneumonitis (n = 4), postinfectious encephalitis (n = 1), and septic arthritis associated with disseminated intravascular coagulopathy (n = 1). All four of these patients recovered completely. In patients with severe involvement, intense abdominal pain was frequently the first sign of dissemination. Abdominal pain and inappropriate ADH syndrome were unexplained and have not been previously described in progressive varicella. A predictable pattern of organ involvement enabled starting therapy early and resulted in the survival of 11 of 15 patients.

Diffuse hypothalamic-hypopituitarism complicating viral meningoencephalitis has been rarely documented. In this report, we describe the syndrome in a 41 yr old male and review the literature. Detailed endocrine studies were performed 1 month after the onset of apparent viral encephalitis. Repeated 08:00 h serum cortisol levels were low, but increased after administration of lysine-vasopressin. Urine 17-hydroxy-corticosteroid (17-OHCS) values rose with prolonged cortrosyn infusion, but failed to respond after administration of metyrapone. Serum thyroxine was decreased; basal levels of serum thyrotropin were low-normal, but there was a prolonged response to tyrotropin (TSH) to thyrotropin releasing hormone (TRH). Basal prolactin was elevated with a minimal response after TRH. Testosterone and gonadotropins were both diminished, and gonadotropins increased (but less than in normal subjects) after injection of gonadotropin releasing hormone (LHRH). The overnight water deprivation test confirmed the presence of diabetes insipidus. In the present context, the abnormal endocrine investigations were strongly supportive of disturbed hypothalamic activity. Hypothalamic-hypopituitarism following viral meningoencephalitis may occur more frequently than previously reported, and thus basal pituitary function should be assessed in all patients with viral meningoencephalitis.

Between November 1996 and January 1997, 14 patients were diagnosed as having infection caused by adenovirus type 7 in a paediatric ward of Asahikawa Kosei Hospital. The age range of the patients was from two months to five years. Their diseases and abnormal laboratory findings were pneumonia in all 14, leukocytopenia in 10, myositis in nine, gastroenteritis in eight, encephalitis in five, liver dysfunction in three, pleuritis in two, inappropriate secretion of antidiuretic hormone syndrome in two, and thrombocytopenia in two. The infected patients, except for the first had been hospitalized in the paediatric ward for treatment of another disease and re-admitted because of high fever and coughing a few days after improvement or discharge. It is thought that the cause of the outbreak was hospital-acquired infection.

Paraneoplastic limbic encephalitis (PLE) is a manifestation of clinico pathological entity encephalo-myelo-neuropathy associated with anti-neuronal antibodies type 1 (ANNA-1 also called anti-Hu). Isolated PLE is rare. We reported a case of PLE in a 61-year-old heavy smoker man. An inappropriate antidiuretic hormone secretion syndrome was associated. Cranial MRI showed hyperintensity in amygdalo-hippocampic regions on T2 weighted sequences which appeared hypointense on T1-weighted sequences without gadolinium enhancement. Anti-Hu antibodies were absent in serum and in CSF. Despite chemotherapy, he died 18 months after disease onset. Our patient presented PLE without myelonouropathy and without ANNA-1 which suggests a different immunopathology.

In patients with acquired immune deficiency syndrome (AIDS), hypoosmolality is frequently observed, whereas hypernatremia is distinctly rare. We report two patients with advanced AIDS and cytomegalovirus (CMV) encephalitis, who developed severe hypernatremia without any thirst sensation, that is, adipsic hypernatremia. Both developed severe hypernatremia of up to 164 and 162 mmol/L, with serum osmolalities of 358 and 344 mOsmol/kg while remaining alert and denying thirst. Serum antidiuretic hormone (ADH) levels were 0.9 and 1.5 pg/mL, inappropriately low for the concomitant serum osmolalities. Vital signs were stable. During hypernatremia, urine osmolalities were 327 and 340 mOsmol/kg, and urine Na+ levels were 56 and 119 mmol/L, respectively. Periventricular white matter lesions were seen on cerebral nuclear magnetic resonance imaging (NMRI) in case 1, but the pituitary appeared normal in both cases. Survival after onset of hypernatremia was 6 and 4 weeks, respectively. Autopsy in case 1 showed typical findings of CMV encephalitis but normal pituitary, confirming that infection with HIV or CMV most likely caused the dysfunction of the central osmostat.

Virusencephalitis is characterised by clinical symptoms of a parenchymatous inflammation. In addition, early mental status changes often occur as a result of virusencephalitis, beside focal neurological deficiencies, epileptic seizures, cerebral compression, even coma. Other pathological manifestations of virusencephalitis are disturbances of the neurohumoral and the endocrine system, which are often recognised and treated too late. This case report describes symptoms, treatment, and complications of a 76 year old female in-patient, who was diagnosed with virusencephalitis. The number of lymphocytes in the cerebrospinal fluid was increased to 30 cells per microliter, liquor albumin was 1705 mg/l, liquor sugar was 53 mg/dl and liquor lactat was 1.9 mmol/l. IgM antibodies against herpes viruses were found in the cerebrospinal fluid and distinct contrasting foci were found near the mammillary bodies, hypothalamus, tractus opticus, hypophyseal stalk and right parahippocampal in the magnetic resonance imaging of the head, indicating a focal herpes simplex encephalitis. Within seven days, the following symptoms developed: akinetic parkinsonian syndrome, central diabetes insipidus with hypernatremia and polyuria (6 l/die), hypothyreosis, adrenal insufficiency with adynamia, sopor, hypotension and even hypophyseal coma. Panhypopituitarism was diagnosed after measuring the basal hormone levels (ACTH, TSH, FT3, FT4, Cortisol, Prolactin, LH, FSH, ADH) and conducting the pituitary stimulation test. The severeness of all symptoms was slightly improved after substitution with antidiuretic hormone at 0.4 microgram/die and administration of hydrocortisone at 50 mg/die. Administration of amantadine sulphate at 0.6 g/die and L-dopa at 187.5 mg/die for 14 days resulted in a complete regression of the parkinsonism. After administration of aciclovir at 2.25 g/die for 21 days a complete regression of the clinical symptoms could be reached in connection with a decrease of 90% in number and size of cerebral contrasting foci in the magnetic resonance imaging of the head. Three month after therapy, clinical examination and blood serum analysis revealed persistent panhypopituitarism. The present case report is the first description of a viral infection on of the central nervous system (CNS) in combination with parkinsonism, diabetes insipidus, persistent panhypopituitarism and hyperprolactinemia. Early treatment of viral infections of the brain can improve a patient's prognosis dramatically. Early determination and early treatment of a patient's neurohumoral parameters is therefore critical to prevent or reverse early mental status changes like attention disturbances, alterations of personality and behavior, apathy, and slowed cognition.
