A stringent procedure for the diagnosis of human T-lymphotropic virus (HTLV) infection was applied to 1,732 volunteer blood donors, 401 patients with various hematological disorders and 78 individuals at high risk for HIV infection. It consisted of a viral lysate-based screening assay (Abbott Laboratories, North Chicago, Ill., USA), and two confirmatory assays (Western blot and radioimmunoprecipitation assay). A confirmed positive sample had to react with at least two different HTLV gene products. Evidence of HTLV infection was not found in either blood donors or patients with hematological disorders. In fact, HTLV infection was only observed in 10 intravenous drug abusers or their sexual partners. Contrary to previous reports that claimed HTLV seroprevalences of between 0.3 and 8% in blood donors from Apulia (Italy), our data suggest that infection with this virus is principally restricted to intravenous drug abusers.

A patient is reported with a typical acute HIV-infection. He presented with an infectious mononucleosis-like illness, which included fever, malaise, sore throat, myalgia, swollen glands and a rash. Seroconversion, documented by serial immunoblotting, occurred within a period of four days. If a patient with a glandular fever-like illness belongs to one of the risk groups, an acute HIV-infection should be seriously considered. In a recent study an association was found between the clinical course of acute HIV-infection and the subsequent course. Treatment of asymptomatic HIV-infected patients is discouraged, except if included in a clinical trial.

Concerns about AIDS, hepatitis and infection control have increased the use of gloves in medical and dental practice. Though generally assumed to be protective, gloves pose many hazards to the practitioner and patient. This is especially significant in dentistry where a large assortment of materials and manipulative techniques are used as part of treatment. Gloves, with relatively large porosities, are poor barriers to viruses. They can promote bacterial growth, skin lesions, toxic and allergic reactions in patient and staff. Gloves are costly, time consuming to use, reduce sensitivity and dexterity. Gloves do not protect the wearer from penetrating injuries, the leading source of HIV and HBV infections in health care workers. The use of gloves is helpful only in those cases where their advantages outweigh liabilities. Governmental regulations, requiring universal glove-wear compliance, may not be in the best public or professional interest.

A previously healthy 29-year-old homosexual man presented with a 4-day history of fever, malaise, sore throat, and bleeding gums. Rhabdomyolysis, acute renal failure, and nephrotic range proteinuria were also present. The patient was found to have acute human immunodeficiency virus (HIV) infection confirmed by the presence of HIV antigen in his serum and subsequent evolution of an HIV antibody profile typical of acute seroconversion. A kidney biopsy revealed acute tubular necrosis and mesangioproliferative glomerulonephritis, with tubuloreticular inclusions. In the presence of otherwise unexplained acute renal failure, rhabdomyolysis, or new onset nephrotic syndrome, acute HIV infection should be considered in the differential diagnosis.

Very few case reports evaluate clinical and laboratory parameters of acute HIV infection. This paper describes seven such cases, four being mononucleosis like disease and one lymphocytic meningitis. Clinical manifestations were fever (7/7), lymphadenopathy (7/7), enlarged liver size (7/7) pharyngitis (6/7), malaise (4/7) and anorexia (4/7). Inversion of the normal T4/T8 ratio was present in 3/5 patients, all with normal absolute values for T4 cells. Moderate transaminase increases were found in 5/6; 5/7 had atypical lymphocytes in blood smear and 5/5 had abnormal mucoprotein levels. All patients had a total remission of clinical symptoms within two weeks. However, the abnormal lymph nodes and the enlarged liver persisted. Follow-up for ten months showed 4/7 patients with all abnormalities resolved and 3/7 still with persistent enlarged lymph nodes.

AIDS-related gastrointestinal disease is common, presenting a challenge to all nutritional support clinicians. Patients frequently suffer from weight loss, diarrhea, malabsorption, and cachexia. Many factors complicate the course of AIDS-related gastrointestinal disease, including decreased food intake (resulting from fatigue and malaise), increased metabolic demand and nutritional requirements, and identifiable gastrointestinal pathology. Gastrointestinal pathology is well-documented, and in approximately 50% of persons with AIDS-related gastrointestinal disease, a causative agent can be identified. In general, treatment of AIDS-related gastrointestinal disease is not always curative. Much of the chronic gastrointestinal dysfunction is caused by recurring opportunistic pathogens that are resistant to chemotherapy. Often, patient care and long-term management can focus only on fluid and electrolyte balance, nutritional support, and symptom control. Even clinically stable patients have been diagnosed as chronically malnourished and, for reasons that remain unclear, are prone to rapid nutritional deterioration during disease exacerbations. Published reports of nutritional assessment and intervention in persons with AIDS are now appearing in the literature. However, the eventual mortality associated with AIDS still results in a hesitancy on the part of many clinicians to prescribe aggressive nutritional support, especially parenteral nutrition. Who to treat and at what stage of illness becomes the question. As new agents, such as AZT, are prescribed on a more frequent basis for persons with AIDS, the use of nutritional support as adjunctive therapy early in the course of disease becomes an issue. Although improving nutrition has not been shown to reverse any of the cellular immunodeficiency caused by HIV infection, quality of life may be improved. In specific cases, nutritional support, whether through diet counseling, food programs, or intervention with enteral or parenteral nutrition, appears to improve strength and endurance, thus enhancing quality of life.

To investigate the pharmacokinetics and effects of intravenous foscarnet, 13 relatively healthy male patients with human immunodeficiency virus infection and a mean CD4+ lymphocyte value of 0.45 x 10(-9) cells per liter were given a continuous intravenous infusion of foscarnet (0.14 to 0.19 mg/kg per min) for 8 to 21 days. Blood and urine samples were taken during and after drug administration to monitor foscarnet concentrations. Lumbar puncture was performed during the infusion in five patients. The concentrations in plasma showed large variations both within and between patients. The disposition of foscarnet could be explained by a triexponential equation (t1/2 lambda 1, 0.40 to 2.52 h; t1/2 lambda 2, 3.20 to 16.7 h; t1/2 lambda 3, 36 to 196 h). Renal clearance accounted for most of the plasma clearance, the difference probably reflecting the passage of foscarnet into bone. Up to 20% of the cumulative dose may have been deposited in bone 7 days postinfusion. Foscarnet was distributed to the cerebrospinal fluid in a concentration varying from 13 to 68% of the simultaneous concentration in plasma. Polyuria and polydipsia were recorded in all patients. There appears to be an association between the degree of malaise, including symptoms such as nausea, vomiting, fatigue, and headache, and concentrations in plasma above 350 mumol/liter.

A mononucleosis-like illness is frequently recognized retrospectively as the first manifestation of infection with human immunodeficiency virus-type 1 (HIV-1). This acute but transient retroviral syndrome may include symptoms such as malaise, fever, sweats, myalgia, arthralgia, maculopapular rash, diarrhea, and lymphocytic meningitis. We observed two intravenous drug users who developed a severe, febrile illness with subsequent oral thrush (one also had biopsy-proven esophageal candidiasis). Both patients had weight loss, arthralgia, myalgia, and fatigue. These symptoms occurred two weeks after needle-sharing and persisted for 7 weeks in one patient and 10 weeks in the other. Both patients had serologic evidence for both acute HIV-1 and cytomegalovirus infection. Cytomegalovirus enhances HIV-1 replication in vitro, presumably by stimulating HIV-1 gene expression. Thus, the observed syndrome suggests that this viral interaction may be clinically significant because it appears to cause severe additional morbidity, which is not typical for primary infection with HIV-1. After 6 months of follow-up, one patient is completely asymptomatic but shows markedly reduced CD4+ lymphocytes. The other patient developed persistent lymphadenopathy after the acute illness, but is feeling well 21 months after infection.

Sera from 385 healthy people aged 1-76 years from rural Punjab, India, were assayed in 1985-1986 for antibodies to hepatitis A, hepatitis B virus (anti-HBc) and hepatitis B serum antigen, and 175 of these sera were screened for HIV antibodies by ELISA. Commercial kits Havab, Ausrah II, and Ausab Test, (Abbott Laboratories, North Chicago, Ill, USA) were used. In cases of positive HBsAG, HBe-Antigen and HBV-DNA were determined by radioimmunoassay. over 98% of persons 20, 89% of those 10-19 and 88% of children 1-9 had hepatitis A antibodies. Markers for hepatitis B virus, anti-HBc, ranged from 3.12-36.9% over the age groups, with a total of 100 or 30% positive. HBsAG positives averaged 3.37%. These data are typical of Indian populations in which everyone 10 years has been exposed to hepatitis A. None of the sera were positive for HIV.

The initial symptoms of an HIV-1 infection were observed in four patients. The following were characteristic for the acute primary phase: (a) initial maculopapular exanthema, especially of the trunk, with occasional transition into a papulovesical appearance; (b) involvement of the oral mucosa, often of aphthous character; and (c) general malaise with fever and lymphadenopathy. The observed cutaneous changes had, on one hand, features of a Coxsackie or mononucleosis exanthema, on the other of secondary syphilis. In three patients seroconversion occurred within 2-6 weeks, the fourth failed to return for follow-up. The listed acute primary symptoms can be used as the earliest indicators of an HIV-1 infection having occurred.
