Cervical papanicolaou smear abnormalities and Chlamydia trachomatis in sexually active adolescent females.

STUDY OBJECTIVE: To examine the effect of cervical Chlamydia trachomatis infection on the prevalence of Papanicolaou (Pap) smear abnormalities in adolescent females. DESIGN: Retrospective study performed by examination of previously obtained cervical C. trachomatis cultures and Pap smear results. SETTING: Urban adolescent health care clinic in the Bronx, New York. PARTICIPANTS: Sexually active females, aged 13 to 23 (mean age: 17.9 years), attending the clinic for evaluation of sexually transmitted diseases. INTERVENTION: Patients who had undergone a gynecological examination with performance of cervical Pap smears and culture for C. trachomatis were enrolled in the study. MAIN OUTCOME MEASURE: Determine the prevalence of cervical C. trachomatis infection and compare cervical smear abnormalities in those with and without infection. RESULTS: Of a study population of 257 females, 24 patients (9.3%) were culture positive for C. trachomatis and 58 patients (22.6%) had significant cervical smear abnormalities, i.e., atypical squamous cells of undetermined significance (ASCUS), low grade squamous intraepithelial lesion (LGSIL), or high grade squamous intraepithelial lesion (HGSIL). The 24 patients infected with C. trachomatis showed the following cervical smear abnormalities: within normal limits-37.5%, benign cellular changes-41.7%, ASCUS-12. 5%, and LGSIL-8.3%. A total of 233 patients (90.7%) were culture negative for C. trachomatis and showed the following cervical smear abnormalities: within normal limits-37.3%, benign cellular changes-39.9%, ASCUS-13.3%, LGSIL-8.6%, and HGSIL-.9%. Statistical analysis suggested no significant differences between the two groups (P >.9 by the Kruskal-Wallace test). CONCLUSIONS: The isolation of C. trachomatis from the cervix of sexually active adolescent females at a single point in time does not impact on the prevalence of significant cervical smear abnormalities.

Cervical Papanicolaou smear abnormalities in inner city Bronx adolescents: prevalence, progression, and immune modifiers.

BACKGROUND: The aim of this study was to quantify the prevalence of cervical smear abnormalities in sexually active adolescents and identify the effect of immune-modifying conditions. METHODS: Two hundred seventy-one females ages 13-22 years attending a clinic for sexually transmitted disease (STD) evaluation had cervical Papanicoloau (Pap) smears and completed sexual history questionnaires. Results of all follow-up Pap smears were obtained. Medical charts were available for 54 patients with cytologic follow-up and were reviewed for the presence of immune-modifying conditions. Follow-up smear results for patients with and without immune-modifying conditions were compared. Abnormality rates for all cervical smears seen in 1995 at Montefiore Medical Center were also obtained. RESULTS: The smear abnormality rate for adolescents was 20. 7% (abnormal squamous cells of undetermined significance [ASCUS], 12. 2%; low grade squamous intraepithelial lesion [LGSIL], 7.7%; high grade squamous intraepithelial lesion [HGSIL], 0.7%) compared with all adult females, for whom the rate was 13.2% (ASCUS, 9.9%; LGSIL, 2.5%; HGSIL, 0.6%; carcinoma 0.2%) (P < 0.0002). Of 20 initial ASCUS patients, 6 (30%) showed LGSIL or HGSIL on follow-up. Chart review allowed the clinical immune status of 54 patients to be determined. Of 14 patients with an immune-modifying condition (9 HIV positive patients, 3 receiving oral steroids, 1 liver transplant patient receiving steroids, and 1 with intestinal lymphangiectasia), 11 (78. 6%) developed or maintained an abnormality on cytologic follow-up. Of 40 patients with no identifiable immune-modifying condition, 11 (27.5%) developed or maintained an abnormality on cytologic follow-up (P < 0.00082). CONCLUSIONS: Sexually active adolescents are at higher risk of developing a significant cervical smear abnormality, especially LGSIL. Patients with an atypical Pap smear or immune-modifying condition require more attentive gynecologic monitoring. Cancer (Cancer Cytopathol)

Are there risk factors for hepatitis B infection in inner-city adolescents that justify prevaccination screening?

PURPOSE: This study was undertaken to determine if homelessness could serve as a marker for previous hepatitis B infection (HBI), and thus justify prevaccination screening. METHODS: One hundred sexually active 13-21-year-olds (mean = 17 years), 74% female, attending an inner-city hospital-based adolescent clinic (HOSP), and 48 sexually active 13-21-year-olds (mean = 19 years), 40% female, attending a clinic based at an urban drop-in center (UDC) for street youth were consecutively enrolled, screened for HBI serum markers and administered a structured interview about sexual practices, sexual abuse, prior sexually transmitted diseases (STDs), and injection drug use. RESULTS: For the HOSP group, 7% were homeless and 4% were HBI positive. In the UDC group, 96% were homeless and 23% were HBI positive. Homelessness was significantly associated with HBI (p < 0.001), and this was corroborated by logistic regression analysis (p < 0.01). Other factors significantly associated with HBI in adolescents included a history of anal sex (p < or = 0.002), anal-receptive sex (p < or = 0.01), genital Chlamydia (p < or = 0.03), prostitution (p < or = 0.03), and sexual abuse (p < or = 0.002). For both populations, gender, sexual orientation, intravenous drug use, and genital sex were not related to HBI. CONCLUSION: These data indicate that homelessness and associated high-risk sexual practices may be indications for prevaccination screening for HBI in adolescents.

Comparison of rapid diagnostic methodologies for Chlamydia and gonorrhea in an urban adolescent population: a pilot study.

PURPOSE: To compare a combination DNA probe test which detects both N. gonorrhoeae (GC) and C. trachomatis (CT) to the current culture methodologies among a population of female adolescents at an urban teaching center. In addition, the probe test for CT was compared to a direct immunofluorescence test. METHODS: All sexually active female adolescents between the ages of 13-21 years who sought care at an urban teaching center from June 1991 through November 1991 and who required testing for sexually transmitted diseases (STDs) were recruited for this study. RESULTS: The probe test was demonstrated to be 66.6% sensitive and 94.9% specific when compared to tissue culture for CT and 50% sensitive and 98.2% specific when compared to culture for GC. We found an overall prevalence of 23.5% for CT and 3.5% for GC. CONCLUSIONS: The two rapid diagnostic tests for CT evaluated in this study demonstrated similar sensitivities. However the probe test offers advantages in that it is easier to perform, skill at reading fluorescence is not required, and one specimen yields results for both CT and GC.

Serologic, immunologic, and clinical features of parenteral drug users from contrasting populations.

We screened inpatient and outpatient parenteral drug users with no clinical evidence of AIDS for immunodeficiency and antibodies to HTLV-III by ELISA. Among 20 outpatient drug users, 5 (25%) were seropositive. Three of these (and 2 who were seronegative) had low T-cell ratios. Over 6 months, 1 seropositive patient with a low ratio developed oral thrush and weight loss. We also studied 13 parenteral drug users hospitalized for conditions other than AIDS. Eight had low T-cell ratios, and at least 6 of these developed AIDS or ARC within 4 months. Serum from 8 of 13 inpatients was available for HTLV-III testing: 6/8 were seropositive and 3 of these 6 were among those developing AIDS or ARC. Abnormal T-cell ratios among all patients were associated with abnormal HTLV-III serology (p = .02). Of the 7 patients who developed AIDS or ARC, 4 were tested for both antibodies and T-cell ratios: all 4 were seropositive and had low ratios. A low ratio (p = .0004), a positive ELISA (p = .014), and abnormalities of both tests (p = .001) were associated with the development of AIDS or ARC. Of the 26 patients without AIDS or ARC, 3 were lost to follow-up and 23 did not develop AIDS or ARC. Six of these 26 had abnormal ratios. Of the 21 patients who did not develop AIDS or ARC and who were tested for HTLV antibodies, 2 were lost to follow-up. Seven of 21 were seropositive and 2/21 were both seropositive and had a low ratio. One of these 2 seropositive patients with low ratios also had lymphadenopathy, but he was lost to follow-up. The other had no adenopathy and remained well until her death from trauma a year later. This study found two populations with very different risks. Six of 13 hospitalized parenteral drug users and only 1 of 20 healthy outpatients developed AIDS or ARC.

Antibodies to pancreatic hormones in diabetics treated before 1964 and after 1974.

The prevalence and titer of antibodies to pancreatic hormones in 21 diabetics treated with USP insulin preparations before 1964 (Group 1) and in another 21 diabetics treated with more highly purified insulin preparations after 1974 (Group 2) were determined. All subjects in Group 1 had antibodies to insulin, 11 had antibodies to pancreatic polypeptide (PP) and 3 to glucagon. In Group 2, 17 had antibodies to insulin, 5 to PP, and 1 to glucagon. Antibodies to somatostatin (SRIF) were not detectable in either group. Group 1 subjects had higher titers of antibodies to insulin, glucagon, and PP than Group 2 subjects. Of note, the Group 1 subjects with the highest insulin antibodies also had the greatest prevalence and highest titers of antibodies to glucagon and PP. In order to address the question of possible differences in immune responsivity between Group 1 and 2 subjects, antibody titers to 4 ubiquitous viral agents were determined. There was no significant difference in viral antibody titers between the groups.

Clinical manifestations of herpesvirus infections in pediatric renal transplant recipients.

We report our experience with 29 symptomatic herpesvirus infections occurring during the course of 87 pediatric transplant procedures performed over the 10-year period, 1973 to 1982. The yearly attack rate ranged from 0.05 to 0.40 case per cumulative patient years at risk. A greater proportion (9 of 14) of children who received more than 10 units of whole blood or packed red blood cells prior to transplantation developed a viral infection compared with those given 10 transfusions or fewer (8 of 25) (P = 0.10). Fever occurred in 22 (76%) children, pulmonary disease in 8 (28%), hepatitis in 11 (35%), leukopenia in 7 (24%), thrombocytopenia in 9 (31%) and central nervous system disease in 3 (10%). Herpesvirus infections were responsible for allograft loss in 7 (24%) patients. However, no differences in the actuarial graft survival curves were noted for transplants performed since 1979 in children with and without viral infection. The etiologic viral agents were cytomegalovirus in 19 (65%) episodes, herpes simplex virus in 8 (28%), Epstein-Barr virus in 2 (7%) and varicella-zoster virus in 2 (7%). Cytomegalovirus-infected patients were younger and more commonly developed primary infection compared with children with herpes simplex virus disease who were more likely to have secondary infection and to manifest a mucocutaneous vesicular rash. We conclude that the etiologic agents and clinical features of herpesvirus infections are similar in pediatric and adult renal allograft recipients. Moreover except for distinctive syndromes such as mucocutaneous vesicular eruption or a central nervous system lymphoma, the various herpes-viruses cause clinically indistinguishable illnesses in pediatric transplant patients with similar end organ involvement and untoward renal consequences.

Kaposi's sarcoma in homosexual men. A seroepidemiologic case-control study.

The cases of 20 male homosexuals with Kaposi's sarcoma and the acquired immunodeficiency syndrome were compared with those of 40 age- and race-matched male homosexual controls. Patients with Kaposi's sarcoma had lower OKT4/OKT8 (T-helper/T-suppressor) ratios than controls, due to smaller numbers of OKT4 cells. Serum IgG concentrations and antibody titers to cytomegalovirus in patients exceeded those in controls, but patients had lower antibody titers to Epstein-Barr virus. Logistic regression analysis comparing patients with controls showed significant relative risks for Kaposi's sarcoma associated with the number of partners per month in receptive anal-genital intercourse, occasions per month of " fisting ," and cytomegalovirus antibody titers. Cytomegalovirus titers also were inversely correlated with OKT4 cell concentrations in the control group. Significantly greater OKT4 cell concentrations were found at diagnosis in HLA-DR5-positive patients than in HLA-DR5-negative patients. Patients who have HLA-DR5 may express disease at lesser degrees of immunodeficiency than HLA-DR5-negative patients.

Acquired immune deficiency syndrome and multiple tract degeneration in a homosexual man.

A 35-year-old homosexual man with acquired immune deficiency syndrome developed progressive dementia and spastic quadriparesis over a two-month period. Severe symmetrical, bilateral degeneration of the corticospinal and frontopontine fibers and cerebellar white matter were found postmortem. Several glial nodules in the brainstem and cerebellum suggested "smoldering" brainstem encephalitis. The possible association of the adenovirus that was isolated from the patient's cerebrospinal fluid to these obscure changes in the central nervous system is discussed.

Longitudinal study of persistent generalised lymphadenopathy in homosexual men: relation to acquired immunodeficiency syndrome.

42 homosexual or bisexual men with persistent generalised lymphadenopathy not attributable to an identifiable cause have been followed longitudinally since February, 1981. Lymphadenopathy was accompanied by fatigue, low-grade fever and/or night sweats (57%), splenomegaly (29%), leucopenia (40%), hypergamma - globulinaemia (76%), and diminished proportion and absolute numbers of helper T cells (95%). Of the 26 patients who had lymph node biopsy, all showed benign reactive hyperplasia. After 15-30 (median 22) months, 8 patients have met criteria for the diagnosis of acquired immunodeficiency syndrome (AIDS). This outcome was associated with previous heavy nitrite inhalant use, with the presence of night sweats, with leucopenia, and with the triad of constitutional symptoms, splenomegaly, and leucopenia. In addition, a lower mean absolute helper T cell count and an increased frequency of anergy to mumps intradermal antigen and of herpes simplex virus isolation distinguished these patients from those remaining in the cohort, who seem to be stable and in some cases to have improved.

Hepatitis B virus infections transmitted from retarded children to their families during brief home exposure.

Hepatitis B virus (HBV) infection is endemic among institutionalized retarded patients, who usually have mild, anicteric hepatitis following nonparenteral exposure. We evaluated the risk of HBV infection (as evidenced by serologic studies) among their contacts, including noninstitutional caretakers, during brief home exposure. Caretakers shaved, bathed, and changed diapers for five patients during home visits or foster home placements. Seven of the 14 caretakers, who were exposed for 3-12 months, developed antibodies (anti-HBc and/or anti-HBs). A mother and her daughter's caretaker were found to have asymptomatic acute HBV infection, and the mother developed antibodies to HBs, HBc, and HBe. In a second household, another caretaker became anti-HBs-positive. Only one of nine play contacts and none of seven casual contacts had markers of past or present HBV infection. The study was a unique opportunity to retrospectively and prospectively monitor HBV transmission. Our results show that noninstitutional caretakers deserve the protection of HBV vaccine to diminish the potential for chronic infection and transmission of HBV infection.

Cytomegalovirus retinitis: a manifestation of the acquired immune deficiency syndrome (AIDS).

Two homosexual males with the "gay bowel syndrome' experienced an acute unilateral loss of vision. Both patients had white intraretinal lesions, which became confluent. One of the cases had a depressed cell-mediated immunity; both patients ultimately died after a prolonged illness. In one patient cytomegalovirus was cultured from a vitreous biopsy. Autopsy revealed disseminated cytomegalovirus in both patients. Widespread retinal necrosis was evident, with typical nuclear and cytoplasmic inclusions of cytomegalovirus. Electron microscopy showed herpes virus, while immunoperoxidase techniques showed cytomegalovirus. The altered cell-mediated response present in homosexual patients may be responsible for the clinical syndromes of Kaposi's sarcoma and opportunistic infection by Pneumocystis carinii, herpes simplex, or cytomegalovirus.

Adenovirus isolates from urine of patients with acquired immunodeficiency syndrome.

13 adenoviruses (Ad) from the urine of 10 patients with acquired immunodeficiency syndrome (AIDS) were characterised by haemagglutination inhibition and restriction endonuclease analysis of their DNA. The haemagglutinin (HA) for 6 of these isolates was found to be that of Ad34/35. 3 other isolates were found to have Ad7 HA and the remaining 4 viruses were found to have both phenotypes. In contrast, the restriction patterns were more homogeneous than anticipated from the serological analysis. 11 isolates had a SmaI-restriction pattern identical to Ad35, and 2 isolates, which lacked one of the 9 Ad35 SmaI-restriction sites, were identical to Ad34. Analyses with other restriction enzymes reinforced the conclusion that the genomes of all isolates resemble that of Ad35 (and Ad34) more than they resembled the previously isolated Ad7 subtypes. The discrepancy between the restriction endonuclease and the serological analyses is best explained by assuming that some of these new isolates are recombinants between a small part (less than 10%) of the Ad7 genome coding for HA and greater than 90% of the Ad35 genome. It is therefore important to characterise both the genotype and the HA for this potentially important group of pathogens in AIDS patients.

Acquired immunodeficiency with reversed T4/T8 ratios in infants born to promiscuous and drug-addicted mothers.

A new syndrome of acquired immunodeficiency has been identified in seven children who were small for gestational age at birth and subsequently have exhibited failure to thrive, lymphadenopathy, parotitis, hepatosplenomegaly, interstitial pneumonia, and recurrent infections. All have a profound cell-mediated immunodeficiency with reversed T4/T8 ratios. Six are hypergammaglobulinemic and one has low IgG levels. The mothers of five of the seven children are sexually promiscuous and/or drug addicts. Three mothers have an immunodeficiency similar to that found in their infants. One of them died at age 33 years with a diagnosis of acquired immunodeficiency syndrome. In five of the children and in three of their mothers, there is evidence of a persistent Epstein-Barr virus (EBV) infection. We speculate that a perinatal or in utero transmission of EBV can induce an "infectious immunodeficiency." The clinical, histopathologic, and immunologic features resemble those described in adult homosexuals and drug addicts.
