The authors report the case of an AIDS patient with rare neurologic manifestations: primary vasculitis of the central nervous system and VIII cranial nerve dysfunction. The authors make a review on the subject, and call special attention for the differential diagnosis. In fact, the patient, a 36 year old woman, with promiscuous life, presented with dizziness, gait ataxia, nausea, headache and hypoacusia. Seven days after the admission, she noted blurred vision in both eyes and soon she became blind. The physical examination showed bilateral optic neuritis and vestibulocochlear dysfunction, stiff neck and fever. No abnormalities were detected on CT scan. CSF showed 40 mononuclear cells/mm3, 79 mg/dl of proteins and normal glucose content. Microbiological research was negative. Serum anti-HIV test was positive. The hypothesis of primary CNS vasculitis was made, and pulse methylprednisolone therapy was introduced with good recovery of neurological syndrome except for persistent amaurosis.

In a series of studies, recombinant interferon-alpha 2a (rIFN alpha 2a, Roferon-A) was administered alone (273 men) or combined with vinblastine (91 men) to patients with acquired immunodeficiency syndrome (AIDS)-related Kaposi's sarcoma (KS). Patients were treated with daily doses of rIFN alpha 2a ranging from 3 to 54 million international units (I.U.) administered intramuscularly. A dose of 36 million I.U. daily for approximately 10 weeks followed by a three times weekly maintenance schedule with the same dose resulted in the best overall therapeutic benefit. An escalating-dose regimen of 3, 9, and 18 million I.U. daily, each for 3 days, followed by 36 million I.U. daily, produced equivalent therapeutic benefit with amelioration of acute toxicity in some patients. Response was more likely in patients without a history of opportunistic infection or B symptoms (fever, night sweats, or weight loss). Response rate increased with increasing baseline CD4 lymphocyte count and was 45.5% in patients with a CD4 count of greater than 400/mm3. Responding patients with a CD4 count of greater than 200/mm3 had a distinct survival advantage over patients who had similar CD4 counts but whose tumors did not regress with therapy. The addition of vinblastine increased toxicity and did not improve the response rate or prolong survival. Side effects included fatigue, fever, chills, myalgias, headaches, anorexia, nausea, diarrhea, and dizziness. Mild abnormalities in hematologic and liver function tests occurred in some patients. Most adverse effects diminished or resolved with continued therapy. We conclude that rIFN alpha 2a offers important therapeutic benefit in a select group of patients with AIDS-related KS.

The acquired immunodeficiency syndrome (AIDS) was first diagnosed in burundi in 1983 when a large number of patients were registered with Kaposi's sarcoma, cryptococcal meningitis, and disseminated candidiasis. In the 1st phase of the disease the vi rus is dormant. In the 2nd phase seroconversion appears; and in the 3rd phase generalized adenopathy emerges. In the 4th phase the full-blown disease appears as a result of cellular immunity deficit with emaciation, fever, sweating, chronic diarrhea, asthenia, blood parameter changes (lymphopenia, thrombocytopenia, leukopenia, anemia, and specific immune disorders). The early phases can be diagnosed by serological tests. During 1989 a group of 155 patients with 1st signs of seropositivity were studied in the central hospital of Bugumbura. The available clinical diagnostic markers were: 56 cases of herpes, 26 cases of generalized adenopathy, 25 cases of inflammatory infiltration of paraganglionic zones, 13 abscesses and phlegmons, 8 cases of chronic proctitis, 8 prurigo cases, 7 cases of chronic pneumonia and bronchitis, 4 cases of paresis of the facial nerve, 4 cases of Kaposi's sarcoma, 2 cases of fresh syphilis, 2 cases of anemia, asthenia, dizziness, and weight loss. Tomo- and zonographical X-ray study of the thorax of 80 patients aged 20-65 (51 men and 29 women) was performed. In 62 patients changes in the lungs were evident. In 2 patients tuberculosis of the lungs was diagnosed: miliary TB in a 26-year woman and disseminated TB in a 31-year man. 2 chronic and 3 bronchial, and 10 interstitial pneumonia cases were diagnosed in 15 patients with average age of 30 years. 4 patients had peribronchial and pneumonic infiltrations. In a group of 45 patients magnified picture showed no deformation in the lungs; and only 5 had respiratory organ pathology. Interstitial pneumonia was the most often diagnosed ailment by X-ray inpatients infected with HIV.

A Caucasian male contracted acquired immune deficiency syndrome (AIDS) following a blood transfusion during heart surgery. Four years later he developed dizziness, dysequilibrium, and emotional disturbances. Neurotologic evaluation implicated central vestibular and auditory dysfunction. Electronystagmographic findings showed ataxic pursuit and optokinetic nystagmus, with a total loss of caloric excitability. The auditory brain stem response indicated delayed absolute and interpeak latencies, and the synthetic sentence identification test yielded abnormally reduced scores bilaterally. Psychological tests suggested organic brain disease with severe anxiety and depression. At autopsy, the AIDS retrovirus was found in mononuclear and multinucleated giant cells in the cortical and subcortical gray matter, cerebral and cerebellar white matter, and throughout the brain stem. Pathologic changes were consistent with the patient's neurotologic profile.

The first case of AIDS positively identified in a non-foreigner in Taiwan was a 25-year-old unmarried male who had practiced homosexuality for ten years. The patient began to have abdominal pain accompanied with loose stools and weight loss in June 1985, followed by fever, cough, headache, dizziness, and loss of memory. Facial hyperpigmentation and extensive oroesophageal candidiasis were noted. Laboratory studies showed severe lymphopenia with a reversed T-helper to T-suppressor ratio, cutaneous anergy and polyclonal gammopathy. Human immunodeficiency virus (HIV) antibodies were positive by ELISA and Western blot, and the virus was isolated from the blood. At autopsy, disseminated cytomegalovirus infection, extensive CNS toxoplasmosis and early lesions of Kaposi's sarcoma were demonstrated. The detection of HIV in the adrenal medulla supports the consensus that the virus is neurotropic.

In this discussion of infection control in patients with acquired immune deficiency syndrome (AIDS), attention is directed to nursing. Due to the fact that the majority of individuals who suffer with AIDS will be homosexual, intravenous drug users, or both, it is essential that the nurse historian be aware of his/her own feelings about the lifestyles of these patients. History-taking should be done in a nonjudgmental manner. A major pitfall to be avoided when taking a history is making assumptions about an individual's sexual preferences or activities based on the response to a simple question about marital status. It is important to note whether or not the person has a monogamous relationship or leads a polyandrous lifestyle. Another area that should be tactfully but explicitly explored when interviewing an individual who is homosexual or bisexual is the number of different sexual partners that he/she has been involved with on a weekly or monthly basis. Whether the patient has a history of sexually transmitted diseases should be determined. The use of recreational drugs should be explored. When taking the history of a client who uses intravenous drugs, it is important for the nurse to record the agents and sites of injection as well as to note whether the individual uses his/her own equipment. When reviewing the major body systems and the presence or absence of related symptoms, the nurse should note whether the client has experienced skin rashes/lesions, swollen lymph nodes, fever, extreme fatigue, weight loss, shortness of breath, changes in bowel habits, cuts or bruises that do not heal, and headaches, dizziness, blurred vision, or stiff neck. The physical examination of the individual with AIDS and an opportunistic infection usually will reveal positive findings in the central nervous system, respiratory system, gastrointestinal system, and/or the integumentary system, as well as the lymphatic system. As the leading cause of morbidity in the compromised host is infection, infection prevention should be regarded as a pragmatic necessity. 2 major things that nurses can do in the acute care setting to control infection are to limit the frequency of invasive or traumatic procedures and to reduce the acquisition of new potential pathogens.

We have observed an unusual low amplitude, slow and featureless electroencephalogram (EEG) pattern in some human immunodeficiency virus (HIV) infected patients without focal lesions on computerized tomography (CT scan) of the head. Out of 17 cases, 13 with AIDS and 4 with HIV positive status, 6 had low amplitude EEGs with slowing, all in the AIDS group. Nine of the 13 AIDS patients were demented, and 4 of these demented patients had slow verbal responses and mutism, indicating advanced HIV-related dementia. All 4 had low amplitude, slow EEGs. The patients with low amplitude, slow EEGs also had atrophy on CT scan by visual assessment and by measurement of ventricular indices. Of 17 age-matched controls referred for non-specific complaints such as headache and dizziness or for psychiatric disorders, 3 had EEGs read as low amplitude with slowing; two had normal mental status and one was psychotic. Although this EEG pattern is not etiologically specific, it may correlate with advanced dementia and atrophy on CT scan in AIDS patients.

The effects of dronabinol on appetite and weight were evaluated in 139 patients with AIDS-related anorexia and > or = 2.3 kg weight loss in a multi-institutional study. Patients were randomized to receive 2.5 mg dronabinol twice daily or placebo. Patients rated appetite, mood, and nausea by using a 100-mm visual analogue scale 3 days weekly. Efficacy was evaluable in 88 patients. Dronabinol was associated with increased appetite above baseline (38% vs 8% for placebo, P = 0.015), improvement in mood (10% vs -2%, P = 0.06), and decreased nausea (20% vs 7%; P = 0.05). Weight was stable in dronabinol patients, while placebo recipients had a mean loss of 0.4 kg (P = 0.14). Of the dronabinol patients, 22% gained > or = 2 kg, compared with 10.5% of placebo recipients (P = 0.11). Side effects were mostly mild to moderate in severity (euphoria, dizziness, thinking abnormalities); there was no difference in discontinued therapy between dronabinol (8.3%) and placebo (4.5%) recipients. Dronabinol was found to be safe and effective for anorexia associated with weight loss in patients with AIDS.

A 17-year-old female was brought in complaining of severe chest pain and difficulty breathing after being raped in the subway. During the assault, she developed palpitations, followed by dizziness, and ultimately loss of consciousness. Her medical history is significant for multiple surgeries for congenital heart disease. At the time of admission she was on furosemide and digoxin therapy but her compliance was doubtful. Both her parents were afflicted with AIDS. She had expressed suicidal thoughts, was sexually active, rarely used condoms and no other methods of birth control, and was regularly using marijuana. Her cardiac condition was promptly stabilized with cardioversion, but this case illustrates the important aspects of the interaction of biopsychosocial factors and chronic illness in adolescence. Serious sequelae, such as noncompliance with medical regimens, unintended pregnancies, sexually transmitted disease, substance abuse, sexual victimization, and suicide attempts, can result from failure to address such concerns in a timely fashion.

Thalidomide (alpha-N-phthalimidoglutarimide), a potent inhibitor of tumor necrosis factor alpha (TNF-alpha), is proving to be a promising drug in the treatment of a number of inflammatory, autoimmune, and HIV-associated disorders. The pharmacokinetics and hemodynamic effects of two single oral doses of thalidomide (100 and 200 mg) were investigated, using a randomized, two-period crossover design, in a group of asymptomatic, male HIV-seropositive subjects. Thalidomide pharmacokinetics were linear at the doses studied, and were best described by a one-compartment model with first-order absorption and elimination processes. The drug was rapidly absorbed, with a mean absorption half-life of 0.95 hr (range, 0.16-2.49 hr) and 1.19 hr (range, 0.33-3.53 hr) after 100- and 200-mg doses, respectively. The corresponding mean Cmax values were 1.15+/-0.24 microg/ml (100 mg) and 1.92+/-0.47 microg/ml (200 mg; p<0.001), which were achieved (Tmax) at 2.5+/-1.5 h and 3.3+/-1.4 hr, respectively. Plasma concentrations of thalidomide declined thereafter, in a log-linear manner, with elimination half-lives of 4.6+/-1.2 hr (100 mg) and 5.3+/-2.2 hr (200 mg). The apparent volumes of distribution (Vdss/F) were 69.9+/-15.6 liters (100 mg) and 82.7+/-34.9 liters (200 mg) while total body clearances (Cl/F) were 10.4+/-2.1 and 10.8+/-1.7 liters/hr, respectively. Significant dose-dependent decreases in supine systolic and diastolic blood pressures were seen for up to 2 hr postdosing; somnolence, headache, dizziness, and confusion were also reported more frequently at the higher dose of thalidomide.
