The purpose of the study was to explore personal fears about AIDS and their consequences in terms of psychological symptoms and behaviour. 1902 individuals, 15 to 64 years old, were selected at random from the Finnish population and interviewed by telephone (94%) or in person (6%). 2.5% regarded AIDS as a personal threat, while 12-13% exhibited psychological symptoms such as insomnia, depression, anxiety or episodes of fear. About 20% had taken measures to prevent HIV infection: 9% had increased their use of condoms, 6% had had themselves tested for HIV, and 5% had taken precautionary measures at work. The psychological status of individuals who feel at risk of AIDS should be assessed within the health care system because persistent feelings of danger may be a sign of incipient psychological decompensation.

Mental symptoms are common in patients with AIDS. Optimal management involves the identification and treatment of underlying mental disorders rather than symptomatic treatment alone. Organic mental disorders are very frequent in AIDS, particularly with seriously ill patients who are medical inpatients. There is a high priori probability that such common symptoms as agitation, irritability, and insomnia will be caused by an organic mental disorder. Psychopharmacology in the patient with AIDS requires considerable caution. Lower doses and careful surveillance for subtle neuropsychiatric side effects are necessary. Routine medical contact with a compassionate physician may be of inestimable value to the patient in coping with the fear and dread that surround the illness.

A therapeutic committee was established in Toulouse Regional University Hospital in order to prescribe zidovudine in patients suffering from AIDS. Using an informatic card, the side effects were evaluated in the 125 patients treated by Zidovudine since the creation of the Committee (from July 1987 to January 1989). Zidovudine was prescribed from May 1987 to June 1988 at the total dose of 1,200 mg daily from June 1988 at 900 mg daily. The most frequent side effects were hematologic: zidovudine used alone (or associated with non hematotoxic drugs) elicited in 21.2% of patients a neutropenia (defined as a number of neutrophils less than 1,000/mm3), in 2.4% anaemia (haemoglobin less than or equal to 9 g/100 ml) and in 4.8% neutropenia associated with anaemia. When zidovudine was administered with hematotoxic drugs, neutropenia, anaemia or the association of both were observed in 12.0%, 3.2% and 2.4% of patients respectively. These hematologic side effects were always regressive after drug cessation. However, it is important to underline the low incidence of hematological side effects on red cells of zidovudine in the present study. This result is unexpected. The other side effects of Zidovudine (used alone) did not led to modification in drug treatment: gastrointestinal disturbances (30.4%), headaches (16.8%), insomnia (13.6%), somnolence (6.4%).... These side effects appeared during the four first months and decreased with the continuation of drug treatment. Their imputation was difficult to define and differentiate to evolution of the disease.

The purine analog 2',3'-dideoxyinosine (ddI), which has anti-retroviral activity in vitro was administered for up to 42 weeks to 26 patients with acquired immunodeficiency syndrome (AIDS) or severe AIDS-related complex (ARC). Ten of these individuals were AZT-intolerant. Eight dose regimens were studied. The drug was orally bioavailable and penetrated into the cerebrospinal fluid (CSF). Comparatively little evidence of an effect against human immunodeficiency virus (HIV) was seen at the lowest four doses. However, patients in the four highest dose groups (ddI at 1.6 milligrams per kilogram intravenously and then greater than or equal to 3.2 milligrams per kilogram orally at least every 12 hours or higher) had increases in their circulating CD4+ T cells (P less than 0.0005), increased CD4/CD8 T cell ratios (P less than 0.01), and, where evaluable, more than an 80% decrease in serum HIV p24 antigen (P less than 0.05). The patients also had evidence of improved immunologic function, had reduced viremic symptomatology, and gained a mean of 1.6 kilogram with these comparatively infrequent dosing schedules (every 8 or 12 hours). The most notable adverse effects directly attributable to ddI administration at the doses used in this study included increases in serum uric acid (due to hypoxanthine release) and mild headaches and insomnia. These results suggest that serious short-term toxicity at therapeutic doses is not an inherent feature in the profile of agents with clinical anti-HIV activity. Further controlled studies to define the safety and efficacy of this agent may be worth considering.

A yin-yang hypothesis is presented linking noradrenergic activity, thromboxane, melatonin, left hemisphere functioning, and cyclic AMP on the one hand, and dopamine, beta-endorphin, calcium, right hemisphere functioning, and cyclic GMP on the other. It is further suggested that there is a yoking of NA, TXA2, serotonin and melatonin in the left hemisphere, and a similar yoking of DA, BE, calcium and cGMP in the right. Evidence is presented to support the hypothesis that each element (NA, TXA2, etc.) on one side can modulate or balance a corresponding element (DA, BE, etc.) on the other. It is suggested that thromboxane is the key element in noradrenergic overactivity and that not taking this into consideration has confounded much prior research. This theory takes into account information processing models as well as pharmacological data and neurochemical theory on coupling of adenylate cyclase to its hormone receptors. Inhibiting noradrenergic overactivity can be obtained by inhibiting thromboxane and concomitantly activating opiate receptors. This protocol may have clinical utility in treating a wide range of disorders such as: anxiety, depression, schizophrenia, sleeplessness, withdrawal states, enuresis, Gilles de la Tourette syndrome, Parkinsonism, Alzheimers, dementia, anorexia, infant ruminations, essential tremor, spasticity of spinal cord injury, diarrhoea, ulcerative colitis, extrapyramidal symptoms, akathisia, neuroleptic malignant syndrome, attention deficit disorder, hyperhidrosis, and possibly AIDS.

Zidovudine (azidothymidine) is a thymidine analogue antiretroviral drug active against human immunodeficiency virus (HIV). In acquired immunodeficiency syndrome (AIDS) and AIDS-related complex (ARC) patients, orally and intravenously administered zidovudine is effective in reducing the incidence of opportunistic infections and neoplasms, increasing helper T lymphocyte numbers, and improving survival rates and quality of life. Adverse effects include serious haematological abnormalities and severe headache, abdominal discomfort, nausea, myalgia and insomnia. In addition, neutropenia and other anaemias frequently limit zidovudine therapy and may result in a need for multiple blood transfusions, dose reductions or withdrawal of the drug. However, despite these problems and the lack of information about some aspects of zidovudine use, zidovudine provides a major hope for HIV-infected patients, and it has rapidly become the standard therapy for improving the quality and duration of the lives of AIDS and ARC patients.

The Stress Clinic at the Maudsley Hospital investigates anxiety due to stress and its pharmacological treatment. Nine stress areas are investigated and their relative severities estimated: social habits, social relationships, life events, psychiatric morbidity, sexual stresses, sleep, stress in old age, menstrual stresses and stress and the heart. From the results a Stress Profile can be constructed for each patient to compare the importance of these different stresses and this can also be used as a measure of change in response to treatment. The benzodiazepine (BZD) anxiolytics can be divided into two groups according to duration of action, medium (8-12 h) and long (30-100 h). Short-acting BZD drugs are particularly useful for situational anxiety, when treatment can be interrupted over night and at weekends. To overcome problems of dependence, withdrawal effects, and daytime side-effects, new non-BZD anxiolytics have been developed: buspirone, alpidem and suriclone. These may be particularly useful for long-term treatment of anxiety. Another alternative is the use of adrenergic beta-blocking drugs of which propranolol and betaxolol have been used in the Clinic, because of their relatively high concentration in the brain when taken orally. Anxiety accompanying coronary heart disease and hypertension can be controlled with anxiolytic drugs and other illnesses with an anxiety component are: sexual disorders, menstrual disorders, asthma, gastro-intestinal conditions, dermatological conditions and chronic illnesses such as malignancy and AIDS. Lack of sleep is a subtle form of stress exerting an adverse effect in almost every illness known to man. BZD hypnotics can be divided into four groups: ultra-short-acting (3-4 h), short-acting (5-6 h), medium-acting (7-8 h) and long-acting (9-12 h). Depending on the nature of the insomnia, ultra-short-acting and short-acting BZD are particularly convenient with minimal disadvantages. Nevertheless, new non-BZD hypnotics are also being developed, i.e. zolpidem and zopiclone. These drugs are relatively short-acting and of equivalent potency to the BZD without problems of dependence etc. Anxiety, as either cause or effect, accompanies many medical illnesses and the use of anti-anxiety drugs as concomitant therapy can both reduce morbidity and improve prognosis.

We conducted a double-blind, placebo-controlled trial of oral azidothymidine (AZT) in 282 patients with the acquired immunodeficiency syndrome (AIDS) or AIDS-related complex. Although significant clinical benefit was documented (N Engl J Med 1987; 317:185-91), serious adverse reactions, particularly bone marrow suppression, were observed. Nausea, myalgia, insomnia, and severe headaches were reported more frequently by recipients of AZT; macrocytosis developed within weeks in most of the AZT group. Anemia with hemoglobin levels below 7.5 g per deciliter developed in 24 percent of AZT recipients and 4 percent of placebo recipients (P less than 0.001). Twenty-one percent of AZT recipients and 4 percent of placebo recipients required multiple red-cell transfusions (P less than 0.001). Neutropenia (less than 500 cells per cubic millimeter) occurred in 16 percent of AZT recipients, as compared with 2 percent of placebo recipients (P less than 0.001). Subjects who entered the study with low CD4 lymphocyte counts, low serum vitamin B12 levels, anemia, or low neutrophil counts were more likely to have hematologic toxic effects. Concurrent use of acetaminophen was also associated with a higher frequency of hematologic toxicity. Although a subset of patients tolerated AZT for an extended period with few toxic effects, the drug should be administered with caution because of its toxicity and the limited experience with it to date.

In a phase I/II trial assessing the toxicity, pharmacokinetics, and activity of the (-)enantiomer of 2'-deoxy-3'-thiacytidine (3TC, lamivudine), 97 patients with AIDS or advanced human immunodeficiency virus (HIV) disease were administered 3TC at 0.5-20.0 mg/kg/day. The cohort's median entry CD4 cell count was 128/mm3 (range, 7-357). A toxic dose was not reached, although some patients reported mild headache, insomnia, and abdominal symptoms, and there was a general downward trend in neutrophil counts at the highest doses. Although subjective and difficult to interpret, increases in energy and appetite were noted, particularly in patients receiving > or = 8.0 mg/kg/day. Immunologic and virologic parameters showed evidence of at least transient anti-HIV activity at those higher doses. Although further studies of 3TC as monotherapy are needed, its favorable toxicity profile, evidence of at least transient clinical activity, and results of in vitro resistance experiments support further clinical testing in combination therapy.

Neuroleptic malignant syndrome (NMS) has been recently described following therapy with non strictly neuroleptic drugs that alter dopaminergic function, such as sulpiride and metoclopramide, and might occur more easily in patients with functional or organic brain disorders. We observed an AIDS patient who suffered from NMS following treatment with clotiapine for insomnia and agitation. Two months later, he presented with a similar syndrome following antiemetic treatment with alizapride. On both occasions, the symptoms completely regressed after the administration of dopaminergic and muscle relaxant drugs. The patient died of pneumonia one month after the last episode. The present paper describes the clinical and pathological findings.
