Thirty-five renal allograft recipients were studied concerning the relationship between cytomegalovirus (CMV), herpes simplex virus (HSV), and opportunistic bacterial and fungal infections. The incidence of opportunistic infections was determined for patients whose tests prior to transplantation were seronegative in complement fixation and indirect hemagglutination assays of CMV antibody and for those patients whose tests were seropositive. Among the six seronegative patients with seronegative tests, four (66%) experienced active CMV infection within two months, and four died of Candida or Aspergillus infection within six months after transplantation. Among the 22 patients with seropositive tests, only one (4%) had a fungal infection and it was nonfatal (P less than .05). The increased morbidity and mortality due to fungal and bacterial infections in transplant recipients with seronegative CMV tests appears, therefore, to be related to primary CMV infection rather than to generalized immunodeficiency.

The tragedy of five patients who contracted human immunodeficiency virus (HIV) infection from a seropositive dentist has alarmed the public. The Centers for Disease Control (CDC) recently revised its recommendations for preventing the transmission of HIV infection to patients during invasive procedures. The CDC abandoned a previous plan to list exposure-prone invasive procedures that HIV-infected health care workers should not perform. The CDC said "expert review panels" should decide on a case-by-case basis whether seropositive health care workers may perform invasive procedures. As of February 1992, the revised recommendations were under review by the US Department of Health and Human Services. Many issues remain to be clarified, such as how these panels will operate and whether decisions will be consistent in similar cases. Disregarding the CDC guidelines or infection-control precautions may further erode public trust and lead to draconian restrictions on HIV-infected health care workers. Physicians and dentists should respond more effectively to public fears about HIV transmission. The challenge is to protect patients while respecting the privacy and livelihood of health care workers.

The ethical issues surrounding the Centers for Disease Control and American Medical Association guidelines for health professionals infected with the human immunodeficiency virus are examined and discussed. Although human immunodeficiency virus transmission risks during surgery are lower than many risks we routinely face, it is not irrational for a patient to want to switch from an infected professional to an uninfected one. The American Medical Association claim that physicians have a duty to avoid imposing any identifiable risks is implausible. Knowing the Centers for Disease Control estimate of risks gives us no way to decide whether the rights of patients or those of handicapped (infected) workers should be given priority. Granting priority to patient rights, either by giving patients the opportunity to know the risks they face and to switch to another provider, or by removing infected providers (compulsory switching), makes us all worse off. This gives us reason to reject these guidelines and emphasize other infection control measures.

We randomized 389 symptomatic patients with human immunodeficiency virus (HIV) infection to ditiocarb sodium (400 mg/m2 orally for 24 weeks) or a placebo. Patients were well balanced according to Centers for Disease Control (CDC) group, CD4+ cell number, and duration of disease prior to entry. Ten new acquired immunodeficiency syndrome (AIDS)-defining opportunistic infections occurred in the treated patients and 21 in the controls. Reduction of new opportunistic infections in the ditiocarb group was significant in all patients (relative risk [RR], 0.44) and in patients with AIDS (CDC groups IV-C1 and IV-D) (RR, 0.12). The size of the effect of ditiocarb was maintained when data were reanalyzed after exclusion of a patient who progressed to Pneumocystis carinii pneumonia who was not strictly CDC-defined (RR, 0.46), or when considering as new opportunistic infections three events, which were clinically active at entry, but for which the definitive diagnosis was made during study (RR, 0.49). The administration of ditiocarb did not induce any major adverse clinical or biological reactions. We conclude that, in this study, ditiocarb was safe and reduced the incidence of opportunistic infections in patients with symptomatic HIV infection.

The case histories of 27 children with Pneumocystis carinii pneumonia (PCP) who were followed up in the AIDS Program at the Children's Hospital of New Jersey, Newark, are reviewed. The mean and median age at PCP diagnosis were 10.8 and 7.7 months, respectively. All of the children had other clinical evidence of infection with the human immunodeficiency virus that was documented prior to the diagnosis of PCP or found at the time of PCP diagnosis. Most patients who presented to the hospital were acutely ill, and complications of treatment occurred in 70%. Overall, 89% of the patients died and 70% survived for less than 6 months after diagnosis of PCP. Median survival after the diagnosis of PCP was only 2.0 months and the median life span of children with PCP was only 14.4 months. Only 40% of children with PCP had CD4 lymphocyte counts at or below the threshold for institution of PCP prophylaxis in adults of 200 x 10(6) cells/L (200 cells/mm3).

The relationship between CD4 T-lymphocyte counts and infection with the human immunodeficiency virus (HIV) is retrospectively investigated for 266 HIV-infected and uninfected children who were born to infected women, including 39 with Pneumocystis carinii pneumonia (PCP), in a population-based surveillance study. Of 21 perinatally HIV-infected children with PCP only 10 (48%) had CD4 T-lymphocyte counts that were less than 500 x 10(6) cells/L (500 cells/mm3), compared with all 18 who were infected via blood transfusions or clotting factors. Among 68 children who were 1 year or younger, 18 (90%) of 20 PCP cases had CD4 T-lymphocyte counts that were less than 1500 x 10(6) cells/L (1500 cells/mm3) compared with only five (10%) of 48 children who did not have the acquired immunodeficiency syndrome (odds ratio, 77.4; 95% confidence interval, 19.7 to 313.4). The mean CD4 T-lymphocyte count was lower for the 39 PCP cases when compared with the 188 children who were at different stages of HIV infection and did not have the acquired immunodeficiency syndrome (AIDS) independent of age. The majority of perinatally HIV-infected children with PCP were 6 months or younger and 50% were previously unknown to be infected. Thus, HIV-positive children should be identified early and followed closely. CD4 T-lymphocyte counts may be useful in monitoring HIV-positive children and determining when to begin PCP prophylaxis.

Since January 1990, human immunodeficiency virus (HIV)-infected patients attending two sexually transmitted disease clinics in Baltimore, Md, have been offered T-lymphocyte subset evaluations. From January through September, CD4+ lymphocyte concentrations were measured in 223 newly diagnosed HIV-infected patients; 50% had fewer than 500 CD4+ T cells and 12% had fewer than 200 CD4+ T cells per cubic millimeter. Most patients were asymptomatic, and, even among patients with fewer than 200 CD4+ T cells, 54% had no symptoms or signs suggestive of advanced HIV infection. Homosexually active men had significantly lower mean CD4+ lymphocyte concentrations than intravenous drug users. Given the substantial numbers of patients with CD4+ concentrations that qualified them for zidovudine therapy, we also assessed their mechanisms of paying for health care. Only 24% of HIV-infected patients had private insurance. Seventy-two percent of patients with fewer than 200 CD4+ T cells either had no insurance or relied on public assistance for health care. Thus, although 50% of asymptomatic individuals identified by routine voluntary HIV screening in an inner-city sexually transmitted disease clinic may benefit from therapy for their disease, 75% of those qualifying for presently recommended therapy either depend on publicly funded health care or have no means of payment for care.

On July 27, 1990, the Centers for Disease Control reported possible transmission of the human immunodeficiency virus (HIV) from a dentist to a patient as a result of patient care. We surveyed a random national probability sample of 300 dentists with a 26-item survey in August and September 1990 to assess reactions to the report (response rate, 59%). Respondents tended not to believe the report (mean was 3.2, median 3.0, where 1 indicated "do not believe" and 7 indicated "believe"). Our sample also tended to believe that transmission of HIV from dentists to patients was unlikely in the future (mean was 2.0, median 2.0, where 1 indicated "not at all likely" and 7 indicated "very likely"). Fifty-one percent of our sample recommended that dentists infected with HIV should discontinue practice, while 38% recommended continuing practice with changes in procedures. Seventy-four percent believed patients should be told if their dentist was infected with HIV. In summary, dentists doubted the possibility of dentist-to-patient transmission of HIV and did not believe the Centers for Disease Control case report, but they did believe infected dentists should refrain from clinical work or modify their practice.

Prevalence of antibody to the human immunodeficiency virus type 1 (HIV-1) was assessed among 10,994 consecutive male and female entrants to 10 correctional systems in the United States. The HIV-1 seroprevalence for the 10 systems ranged from 2.1% to 7.6% for men and 2.5% to 14.7% for women; seroprevalence among women was higher than among men across nine of 10 systems. Using age 25 years to divide the population, HIV-1 prevalence among young women (5.2%) was significantly higher than among young men (2.3%), but similar to that in both older women (5.3%) and older men (5.6%). Overall, HIV-1 rates for nonwhites (4.8%) were higher than those for whites (2.5%). Although categories were identified across correctional systems, which may serve to focus prevention programs, variability in rates among correctional systems indicates that program planning must take local conditions into consideration.

Because soldiers in the US Army are recurrently tested for the presence of antibody to the human immunodeficiency virus (HIV), HIV seroconversion rates can be directly measured. From November 1985 through October 1989, 429 HIV seroconversions were detected among 718,780 soldiers who contributed 1,088,447 person-years of follow-up time (HIV seroconversion rate, 0.39 per 1000 person-years). Period-specific seroconversion rates declined significantly from 0.49 per 1000 person-years (November 1985 through October 1987) to 0.33 per 1000 person-years (November 1987 through October 1988) to 0.29 per 1000 person-years (November 1988 through October 1989). The HIV seroconversion risk among active-duty soldiers was significantly associated with race/ethnic group, age, gender, and marital status. Based on these trends, we estimate that approximately 220 soldiers (95% confidence interval, 160 to 297 soldiers) were infected with HIV during 1989 and 1990, with potentially fewer in future years.
