Acquired immunodeficiency syndrome in children: report of the Centers for Disease Control National Surveillance, 1982 to 1985.

Since national surveillance for acquired immunodeficiency syndrome (AIDS) began in 1981, the Centers for Disease Control (CDC) has received reports of more than 20,000 cases of AIDS in the United States. As of December 31, 1985, 307 of these cases had been diagnosed in children younger than 13 years of age. The number of cases is increasing rapidly. The number of cases reported in 1985 more than doubled those reported in 1984. The major risk factors in children for acquiring infection with the causative agent, human immunodeficiency virus (HIV), were having a mother known to be infected and/or at increased risk for infection and receiving a transfusion of blood or blood products. Of the 307 children with AIDS, 73% were reported from one of four states: New York, New Jersey, Florida, and California. Most AIDS cases in children occur in black or Hispanic infants and toddlers. The estimated incubation period for AIDS in children has increased each surveillance year, with the longest incubation exceeding 7 years. The prognosis for children with AIDS is poor and infants less than 1 year of age have the shortest survival time following diagnosis. Continued national surveillance for AIDS is mandatory for establishing effective prevention programs to control the spread of the disease. The CDC encourages all health care personnel to report cases of AIDS to their public health departments.

Lack of transmission of HTLV-III/LAV infection to household contacts of patients with AIDS or AIDS-related complex with oral candidiasis.

To determine the risk of transmission of human T-cell lymphotropic virus Type III/lymphadenopathy-associated virus (HTLV-III/LAV) to close but nonsexual contacts of patients with the acquired immunodeficiency syndrome (AIDS), we studied the nonsexual household contacts of patients with AIDS or the AIDS-related complex with oral candidiasis. Detailed interviews, physical examinations, and tests for serum antibody to HTLV-III/LAV were performed on 101 household contacts of 39 AIDS patients (68 children and 33 adults), all of whom had lived in the same household with an index patient for at least three months. These contacts had shared household items and facilities and had close personal interaction with the patient for a median of 22 months (range, 3 to 48) during the period of presumed infectivity. Only 1 of 101 household contacts--a five-year-old child--had evidence of infection with the virus, which had probably been acquired perinatally rather than through horizontal transmission. This study indicates that household contacts who are not sexual partners of, or born to, patients with AIDS are at minimal or no risk of infection with HTLV-III/LAV.

Sex of interviewer, place of interview, and responses of homosexual men to sensitive questions.

Effects of sex of interviewer and place of interview on the responses of 57 AIDS patients and 145 other homosexual men were studied. Data on sensitive topics were collected by five male and three female medical officers at places convenient to respondents. Male physicians recorded fellatio more frequently, but female physicians recorded younger ages of initiating homosexual activities and more frequent use of certain recreational drugs. These differences apparently were due to different patterns of sexual contact and drug use in four cities. Patients with AIDS tended to be interviewed in hospitals and doctors' offices, other men tended to be interviewed in hotel rooms, and patients tended to be different from other men. After adjustments were made for confounding, sex of interviewer and place of interview seemed to have little influence on the answers obtained.

A population-based study of hemolytic-uremic syndrome in Oregon, 1979-1982.

The authors conducted a retrospective hospital-based chart review of cases of hemolytic-uremic syndrome among children less than or equal to 18 years of age, hospitalized in Oregon during the four-year period from January 1979 to December 1982. Thirty children with hemolytic-uremic syndrome living in Oregon were hospitalized during this period, for an average annual incidence of 0.97 cases per 100,000 children. Seventy per cent of cases occurred in children under five years of age, for an incidence of 2.65 cases per 100,000 children. Twenty-seven (90%) of the 30 children were white, and 17 (57%) were female. Twenty-four (80%) had a diarrheal prodromal illness including 20 who had bloody diarrhea. Twelve children (40%) acutely required peritoneal dialysis, and two (7%) developed chronic renal failure. Three children died, for a case fatality ratio of 10%. Sixty per cent of the 30 cases occurred during the summer and early fall months. Geographic clustering was also evident. Hemolytic-uremic syndrome is a rare but endemic disease in Oregon and may occur in small clusters. Although descriptions of several large series of patients have been published, this study describes the first statewide population-based study of this syndrome.

Kawasaki syndrome: a controlled study of an outbreak in Wisconsin.

The etiology of Kawasaki syndrome remains unestablished, although a possible role has been suggested for exposure to the application of carpet shampoo, house dust mites, and rickettsial infection. During an outbreak of 20 cases of Kawasaki syndrome that occurred in southeastern Wisconsin from November 1982 through March 1983, a case-control study was done of 15 cases and 30 matched controls. The study included questionnaire administration, dust collection from homes, and serum specimen collection. Only one patient had been exposed to a shampooed carpet within 30 days before onset of illness. No differences were noted between cases and controls in the degree of exposure to house dust mite-associated factors in the home, nor in the occurrence, density and species-specific prevalence of house dust mites in the home. Meadow voles exposed to house dust mites from the homes of patients did not develop serologic or pathologic evidence of infection due to rickettsiae in the spotted fever and typhus groups or Coxiella burnetii. Anti-mite-specific immunoglobulin E was not detected in serum specimens from cases or controls. Results from this study do not support hypotheses suggesting that the development of Kawasaki syndrome is associated with exposure to application of carpet shampoo, house dust mites, or rickettsial infection.

Virologic studies of HTLV-III/LAV in pregnancy: case report of a woman with AIDS.

The number of cases of acquired immunodeficiency syndrome (AIDS) in women is increasing. As of December 30, 1985, 1075 cases in women had been reported to the Centers for Disease Control; 81% of these cases occurred in women of childbearing age (15 to 45 years). The human T-lymphotropic virus type III/lymphadenopathy-associated virus (HTLV-III/LAV) can be transmitted from mothers to their infants. Described is a woman with transfusion-acquired AIDS who was six weeks' pregnant at the time Pneumocystis carinii pneumonia was diagnosed. Despite the fact that HTLV III/LAV was isolated from her peripheral lymphocytes throughout pregnancy, transmission of the virus to her infant or husband does not appear to have occurred.

Acquired immunodeficiency syndrome and HTLV-III/LAV infection.

Although AIDS and HTLV-III/LAV infection are rare in adolescents, the number of infected adolescents in increasing. Adolescents may place themselves at risk for becoming infected through sexual exposure and use of intravenous drugs. The management of infected adolescents includes management of social, emotional, and psychologic problems as well as the physical condition. Providers of health and social care for adolescents need to be informed regarding HTLV-III/LAV infection in this population. Prevention depends largely on appropriate education of the teenage population.

Hemolytic-uremic syndrome--an outbreak in Sacramento, California.

Between July and November 1982, 14 cases of the hemolytic-uremic syndrome occurred in the Sacramento, California, metropolitan area; 9 of the 14 patients lived within a 7.5-mile radius in northeast Sacramento, 10 were female, 12 were white non-Hispanic and 13 were children with a mean age of 3.6 years. Of the 14 patients, 13 were admitted to hospital; 7 required peritoneal dialysis. The 14th child, a 3-month-old white female infant, was found dead in her crib and had renal histopathologic findings consistent with the hemolytic-uremic syndrome. Of the 13 nonfatal cases, 12 patients had diarrhea before being admitted to hospital. A case-control study involving 11 cases and 22 controls did not show any significant differences in exposure to a variety of possible risk factors including restaurants, specific foods and water supply. Stool specimens were negative for enteric bacterial pathogens by culture and for viruses by tissue culture assay, suckling mouse inoculation and immune electron microscopy; no serologic evidence was found for infection due to enteroviruses, respiratory viruses or arenaviruses. Two of four children tested, however, showed serologic evidence of infection by Vero-cytotoxin-producing Escherichia coli. These 14 cases represent one of the largest reported outbreaks of the hemolytic-uremic syndrome in the United States.

Changing epidemiology of Reye syndrome in the United States.

The average annual incidence of Reye syndrome reported through national surveillance was lower during 1981 to 1984 than during the previous five surveillance years. This is accounted for by a decrease in cases among children younger than 10 years of age; the number of cases in 10- to 19-year-old persons remained relatively stable during this period. The overall decline in incidence and the differing age-specific incidence trends are apparent for both varicella-associated cases and for nonvaricella-associated cases. During 1985, the incidence has been much lower than during any previous year since surveillance was initiated; this most recent decrease includes children 10 to 19 years of age. Independently conducted surveys suggest that the prevalence of salicylate use for viral illnesses has decreased among children in recent years, particularly among children younger than 10 years of age. The changing epidemiology of Reye syndrome may reflect, in part, the declining use of salicylates among children and teenagers in the United States.

Kawasaki syndrome. Is exposure to rug shampoo important?

In the winter of 1982-1983, two clusters of cases of Kawasaki syndrome (KS) provided an opportunity to examine further the possible association among KS, antecedent illnesses, and carpet shampooing and related activities. The two clusters involved 16 patients with onsets between October and January, with seven cases occurring in two adjacent counties in New York (Herkimer and Oneida) and nine in Kent County, Michigan. None of the 11 children with KS included in a case-control study had been exposed to shampooed carpets during the month prior to the onset of KS. Only four (36%) of 11 children with KS, compared with 13 (59%) of 22 control subjects, reported a respiratory antecedent illness within 30 days prior to the onset of KS (odds ratio = 0.50, 95% confidence limits = 0.12 to 2.03). The previously observed associations of KS with antecedent respiratory illness and carpet shampooing remain unexplained and undocumented in these outbreaks.

National Reye syndrome surveillance, 1982.

Despite the fact that influenza B was the primary influenza virus strain during the winter of 1981-1982, only 213 cases of Reye syndrome were reported to the Centers for Disease Control (CDC) between Dec 1, 1981 and Nov 30, 1982. This national reported incidence of 0.33 cases per 100,000 children less than 18 years of age is the lowest reported incidence since the Centers for Disease Control began surveillance in 1973. This relatively low incidence probably reflected, at least in part, the fact the influenza B activity was spotty and the illness relatively mild the winter of 1981-1982. The 213 cases were reported from 43 states; and in 56% of the patients, Reye syndrome occurred following a respiratory illness. The mean age of the children was 7.0 years; there were equal numbers of girls and boys; and 93% were white. Of the ten black patients, 80% were less than 1 year of age compared with 9% of the white patients. Of the 208 patients with reported admission stage, 45% were admitted in stage I or 0, a slightly lower proportion than that observed in the previous 2 years. Salicylate levels were obtained in 55% of the patients and were reported as "detectable" in 81% compared with 96% in 1981 (P = .003, chi 2). Of the 200 patients with known outcome, 70 patients died (a case fatality ratio of 35%).

National case-control study of Kaposi's sarcoma and Pneumocystis carinii pneumonia in homosexual men: Part 1. Epidemiologic results.

To identify risk factors for the occurrence of Kaposi's sarcoma and Pneumocystis carinii pneumonia in homosexual men, we conducted a case-control study in New York City, San Francisco, Los Angeles, and Atlanta. Fifty patients (cases) (39 with Kaposi's sarcoma, 8 with pneumocystis pneumonia, and 3 with both) and 120 matched homosexual male controls (from sexually transmitted disease clinics and private medical practices) participated in the study. The variable most strongly associated with illness was a larger number of male sex partners per year (median, 61 for patients; 27 and 25 for clinic and private practice controls, respectively). Compared with controls, cases were also more likely to have been exposed to feces during sex, have had syphilis and non-B hepatitis, have been treated for enteric parasites, and have used various illicit substances. Certain aspects of a lifestyle shared by a subgroup of the male homosexual population are associated with an increased risk of Kaposi's sarcoma and pneumocystis pneumonia.
