- Abstract
Objective: To determine whether abnormalities of cellular immunity are present and linked to early wheezing after bronchiolitis. Methods: We prospectively studied 26 infants hospitalized for a first episode of bronchiolitis and without any prior immune, cardiac, or respiratory disease. Blood was obtained at the time of enrollment and 5 months later for the assessment of the total cellular and differential counts, CD4^+ (helper) and CD8^+ (suppressor/cytotoxic) lymphocytes, and the activation markers CD23 (low-affinity immunoglobulin E receptor) and CD25 (interleukin-2 [IL-2] receptor). The cytokines interferon gamma (T-helper [TH] type-1 cytokine) and IL-4 (TH-2) were measured in plasma and in vitro after stimulation with IL-2 or with the house-dust mite (Dermatophagoides farinae) antigen. A daily log of episodes of wheezing was kept by parents after discharge. Results: We found an increase in blood eosinophils, an increased percentage of CD4^+, CD25^+, and CD23 ^+ lymphocytes in subjects at 5 months compared with the time of bronchiolitis and with healthy subjects of the same age (p <0.05). Plasma IL-4 levels, although not different from those of healthy subjects, also increased significantly. Peripheral blood lymphocytes from infants who wheezed produced more IL-4 in vitro, 5 months after bronchiolitis, in response to D. farinae antigen. In babies who wheezed, a positive correlation was found between the total number of days that wheezing occurred and the blood eosinophil count. Babies who wheezed more often (>20 days) had more peripheral blood basophils and eosinophils, and peripheral blood lymphocytes obtained from these subjects at the time of bronchiolitis produced less interferon gamma on stimulation with IL-2. Conclusions: Bronchiolitis is followed by activation of cellular immunity, and early wheezing in infants is associated with a TH-2 response. (J Pediatr 1997;130:584-93)

- Abstract
BACKGROUND: The efficacy and safety of adding a protease inhibitor to two nucleoside analogues to treat human immunodeficiency virus type 1 (HIV-1) infection are not clear. We compared treatment with the protease inhibitor indinavir in addition to zidovudine and lamivudine with treatment with the two nucleosides alone in HIV-infected adults previously treated with zidovudine.\ud \ud METHODS: A total of 1156 patients not previously treated with lamivudine or protease inhibitors were stratified according to CD4 cell count (50 or fewer vs. 51 to 200 cells per cubic millimeter) and randomly assigned to one of two daily regimens: 600 mg of zidovudine (or stavudine) and 300 mg of lamivudine, or that regimen with 2400 mg of indinavir. The primary end point was the time to the development of the acquired immunodeficiency syndrome (AIDS) or death.\ud \ud RESULTS: The proportion of patients whose disease progressed to AIDS or death was lower with indinavir, zidovudine, and lamivudine (6 percent) than with zidovudine and lamivudine alone (11 percent; estimated hazard ratio, 0.50; 95 percent confidence interval, 0.33 to 0.76; P=0.001). Mortality in the two groups was 1.4 percent and 3.1 percent, respectively (estimated hazard ratio, 0.43; 95 percent confidence interval, 0.19 to 0.99; P=0.04). The effects of treatment were similar in both CD4 cell strata. The responses of CD4 cells and plasma HIV-1 RNA paralleled the clinical results.\ud \ud CONCLUSIONS: Treatment with indinavir, zidovudine, and lamivudine as compared with zidovudine and lamivudine alone significantly slows the progression of HIV-1 disease in patients with 200 CD4 cells or fewer per cubic millimeter and prior exposure to zidovudine.

- Abstract
Introduction: Although society still holds age-related stereotypes dismissing the sexuality of aging individuals, older adults remain sexually active and find sexuality to be an important part of their quality of life. Primarily oriented toward a biomedical and dysfunctional lens, prior research neglected the subjective well-being of elderly individuals, especially partnered adults and couples aged 60 years or more. Shedding a more positive light on this area of life could promote older individuals' and couples' sexual well-being., Objectives: This scoping review aimed to synthetize the studies including community samples of partnered adults or couples over 60 who reported on various indicators of subjective sexual well-being including sexual satisfaction, distress, and function using validated measures., Methods: Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMAScR), the electronic literature search was conducted using PubMed, PsycINFO, Medline, and CINAHL for peer-reviewed journal articles published before July 2023., Results: Results showed how relational variables such as relationship satisfaction and intimacy emerge as important correlates of older adults' sexual well-being., Conclusion: Avenues for future research arising from gaps in the studies identified thorough this scoping review, including the underrepresentation of sexual/gender diverse individuals and the use of single and/or non-validated items to assess sexual well-being, are discussed., (© The Author(s) 2024.

- Abstract
Background: There are inconsistent data on the risk factors for Clostridium difficile infection (CDI) in the literature. Aims: To use two C. difficile infection (CDI) case-control study groups to compare risk factors in hospitalized patients with diarrhea across different countries. Methods: A multi-center group of CDI cases/controls were identified by standardized testing from seven countries from the prior EUropean, multi-center, prospective bi-annual point prevalence study of CLostridium difficile Infection in hospitalized patients with Diarrhea (EUCLID). A second group of CDI cases/controls was identified from a single center in Germany [parallel study site (PSS)]. Data were extracted from the medical notes to assess CDI risk factors. Univariate analyses and multivariate logistic regression models were used to identify and compare risk factors between the two groups. Results: There were 253 and 158 cases and 921 and 584 controls in the PSS and EUCLID groups, respectively. Significant variables from univariate analyses in both groups were age ≥65, number of antibiotics (OR 1.2 for each additional antibiotic) and prior hospital admission (all p < 0.001). Congestive heart failure, diabetes, admission from assisted living or Emergency Department, proton pump inhibitors, and chronic renal disease were significant in PSS (all p < 0.05) but not EUCLID. Dementia and admitted with other bacterial diseases were significant in EUCLID ( p < 0.05) but not PSS. Following multivariate analyses, age ≥ 65, number of antibiotics and prior hospital admission were consistently identified as CDI risk factors in each individual group and combined datasets. Conclusion: Our results show that the same CDI risk factors were identified across datasets. These were age ≥ 65 years, antibiotic use and prior hospital admission. Importantly, the odds of developing CDI increases with each extra antibiotic prescribed., (Copyright © 2020 Davies, Lawrence, Berry, Davis, Yu, Cai, Gonzalez, Prantner, Kurcz, Macovei, Pituch, Nováková, Nyč, Gärtner, Berger, Oleastro, Cornely, Vehreschild, Pedneault and Wilcox.)

- Abstract
Neisseria meningitidis carriage data are necessary to inform serogroup B (NmB) immunization program implementation. This longitudinal study compared detection methods to measure N. meningitidis throat carriage prevalence in Quebec from November 2010 to December 2013 using cultured swab isolates and direct swab PCR from students in ninth grade (aged 13 to 15 years; n = 534) and eleventh grade/college entry (16 to 18 years; n = 363) and in university students in dormitories (18 to 25 years; n = 360) at 3 time points per group. Meningococcal and NmB carriage rates were lower in ninth- and eleventh-grade/college entry students than university students, regardless of methodology. Genotyping cultured isolates by PCR detected NmB and non-NmB in 2.1% and 7.3% of ninth-grade students, in 1.7% and 7.2% of eleventh-grade/college entry students, and in 7.5% and 21.9% of university students, respectively. NmB acquisition rates were 1.9, 0.7, and 3.3 per 1,000 person-months across respective age groups. Most NmB isolates (94.7%, 76.9%, and 86.8%, respectively) expressed subfamily A factor H binding-protein (fHBP) variants. The most common non-NmB serogroups were NmY (1.7%/1.1%) from ninth grade and eleventh grade/college entry and NmW (2.8%) from university students. Genomic analyses detected disease-associated sequence types in carriage isolates, and carriage could persist for months. This is the largest longitudinal carriage study in Canada and the first to report fHBP variants in NmB carriage isolates in healthy Canadians. These data contribute to identification of the optimal window for NmB vaccination in precollege adolescents and provide a baseline for investigating NmB vaccination effects on carriage in this population. IMPORTANCE Disease caused by Neisseria meningitidis is associated with serious complications and a high fatality rate. Asymptomatic individuals can harbor the bacterium in the throat, a state known as "carriage," which can lead to person-to-person spread of the pathogen. This study examined N. meningitidis carriage from 2010 to 2013 among 2 groups in the Quebec City region: ninth-grade students (aged 13 to 15 years), who were also followed in their last year of high school (eleventh grade/college entry; 16 to 18 years), and university students (18 to 25 years); both groups have been shown in some other geographic regions to have high rates of carriage. This study demonstrated that N. meningitidis carriage rates were higher among university students in dormitories than ninth-grade and eleventh-grade/college entry students. Understanding carriage rates in these age groups leads to better strategies to control N. meningitidis by targeting vaccination to those responsible for transmission within the population., (Copyright © 2018 Gilca et al.)

- Abstract
Introduction: Clostridium difficile is a significant cause of morbidity and mortality in hospitals, nursing homes, and long-term care facilities. The bacteria can produce 3 toxins, of which the C. difficile toxin A and C. difficile toxin B are the principal virulence factors for C. difficile-associated disease., Methods: A phase 1, first-in-human, placebo-controlled, dose-escalation study was performed to assess the safety and immunogenicity of an investigational vaccine candidate consisting of genetically and chemically detoxified, purified toxins A and B. The toxoids, either alone or in combination with aluminum hydroxide (Al(OH)3), were administered to healthy adults 50-85 years of age at antigen dose levels of 50, 100, or 200 μg in a 3-dose regimen administered at 0, 1, and 6 months., Results: Overall, the C. difficile vaccine formulations and doses administered were generally well tolerated. Local reactions and systemic events were predominantly mild to moderate, were more common in the 50-64-year age cohort, and comprised mostly injection site pain, headache, and fatigue. In subjects who received the vaccine formulations, both the toxin A- and toxin B-specific neutralizing antibody geometric mean concentrations increased substantially at 1 month after Dose 2 and after Dose 3 compared to baseline. In the 50-64-year age cohort, geometric mean fold rises (GMFRs) in toxin A-specific neutralizing antibodies from baseline at Month 7 ranged from 59.19 to 149.23 in the vaccine groups compared to 2.47 in the control group. For toxin-B specific neutralizing antibodies, the GMFRs from baseline at Month 7 ranged from 116.67 to 2503.75 in the vaccine groups compared to 2.48 in the control group. In the 65-85-year age cohort, GMFRs in toxin A-specific neutralizing antibodies from baseline at Month 7 ranged from 42.73 to 254.77 in the vaccine groups compared to 2.03 in the control group. For toxin-B specific neutralizing antibodies, the GMFRs from baseline at Month 7 ranged from 136.12 to 4922.80 in the vaccine groups compared to 1.58 in the control group. Potent antitoxin neutralizing responses were still evident in immunized subjects in both age groups at Month 12. Although there was no clear dose-level response pattern, the data suggest that both the antitoxin A- and B-specific neutralizing responses were trending higher in the toxoid-only groups compared to the toxoid+Al(OH)3 groups. Furthermore, the magnitude of the immune response was similar in the 2 age cohorts., Conclusion: The vaccine formulations studied in this phase 1 study were immunogenic and well tolerated. The results presented support further development of the C. difficile vaccine candidate in a larger population of subjects to determine the optimal dose and immunization schedule., Clinical Trial Registry: NCT01706367., (Copyright © 2016.

- Abstract
Neisseria meningitidis serogroup B (MnB) is a leading cause of bacterial meningitis; however, MnB is most commonly associated with asymptomatic carriage in the nasopharyngeal cavity, as opposed to the disease state. Two vaccines are now licensed for the prevention of MnB disease; a possible additional benefit of these vaccines could be to protect against disease indirectly by disrupting nasopharyngeal carriage (e.g., herd protection). To investigate this possibility, accurate diagnostic approaches to characterize MnB carriage isolates are required. In contrast to invasive meningococcal disease (IMD) isolates, which can be readily serogrouped, carriage isolates often lack capsule expression, making standard phenotypic assays unsuitable for strain characterization. Several antibody-based methods were evaluated for their abilities to serogroup isolates and were compared with two genotyping methods (real-time PCR [rt-PCR] and whole-genome sequencing [WGS]) to identify which approach would most accurately ascertain the polysaccharide groups associated with carriage isolates. WGS and rt-PCR were in agreement for 99% of IMD isolates, including those with coding sequences for MnB, MnC, MnW, and MnY, and the phenotypic methods correctly identified serogroups for 69 to 98% of IMD isolates. In contrast, only 47% of carriage isolates were groupable by genotypic methods, due to mutations within the capsule operon; of the isolates identified by genotypic methods, ≤43% were serogroupable with any of the phenotypic methods tested. These observations highlight the difficulties in the serogrouping and capsular genogrouping of meningococcal carriage isolates. Based on our findings, WGS is the most suitable approach for the characterization of meningococcal carriage isolates., (Copyright © 2015, American Society for Microbiology. All Rights Reserved.)

- Abstract
Objectives: Recent development of serogroup B meningococcal (MenB) vaccines highlights the importance of pharyngeal carriage data, particularly in adolescents and young adults, to inform implementation strategies. We describe current UK carriage prevalence in this high risk population and compare methods of carriage detection., Methods: In this multisite study, pharyngeal swabs were collected on 3-4 occasions over 6-12 months, from 1040 school and university students, aged 10-25 years. Meningococcal carriage was detected by standard culture combined with seroagglutination or PCR of cultured isolates, or by direct PCR from swab. The factor H binding protein (fHBP) variants present in meningococcal isolates were determined., Results: Meningococcal serogroups B and Y were most common, with carriage up to 6.5% and 5.5% respectively, increasing throughout adolescence. Identification by seroagglutination was often unreliable, and the sensitivity of direct PCR detection was 66% compared to culture combined with PCR. Of MenB isolates, 89.1% had subfamily A variants of fHBP. The acquisition rate of MenB carriage was estimated at 2.8 per 1000 person-months., Conclusions: If vaccination is to precede the adolescent rise in MenB carriage, these data suggest it should take place in early adolescence. Studies assessing vaccine impact should use molecular methods to detect carriage., (Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.)

- Abstract
Background: Induction of HIV-1-specific CD4(+) T-cell responses by therapeutic vaccination represents an attractive intervention to potentially increase immune control of HIV-1., Methods: We performed a double-blinded, randomized, placebo-controlled clinical trial to determine the safety and immunogenicity of GlaxoSmithKline Biologicals' HIV-1 gp120/NefTat subunit protein vaccine formulated with the AS02(A) Adjuvant System in subjects with well-controlled chronic HIV-1 infection on highly active antiretroviral therapy. Ten individuals received the vaccine; whereas adjuvant alone or placebo was given to 5 subjects each. Immunogenicity was monitored by intracellular cytokine flow cytometry and carboxyfluorescein succinimidyl ester-based proliferation assays., Results: The vaccine was well tolerated with no related serious adverse events. Vaccine recipients had significantly stronger gp120-specific CD4(+) T-cell responses which persisted until week 48 and greater gp120-specific CD4(+) T-cell proliferation activity as compared with controls. In the vaccine group, the number of participants who demonstrated positive responses for both gp120-specific CD4(+) T-cell interleukin-2 production and gp120-specific CD8(+) T-cell proliferation were significantly higher at week 6., Conclusions: The gp120/NefTat/AS02(A) vaccine induced strong gp120-specific CD4(+) T-cell responses and a higher number of vaccinees developed both HIV-1-specific CD4(+) T-cell responses and CD8(+) T-cell proliferation. The induction of these responses may be important in enhancing immune-mediated viral control.

- Abstract
This randomized double-blind study aimed to determine the safety and immunogenicity of a gp120/NefTat candidate human immunodeficiency virus type 1 (HIV-1) vaccine formulated with one of three different Adjuvant Systems (AS02(A), AS02(V) and AS01(B)) in healthy HIV-seronegative adults. All vaccine formulations induced strong HIV-specific CD4(+) T-cell responses characterized by high lymphoproliferative capacity and IL-2 production that were still detectable 18 months after last immunization, with strongest responses seen in the AS01(B) group. Broad coverage was demonstrated against gp120, and to a lesser extent Nef, derived from the most common circulating clades (B, C and circulating recombinant form [CRF]-01). All vaccine formulations exhibited acceptable safety and reactogenicity profiles. The demonstration of superior CD4(+) T-cell induction by AS01(B) provides important guidance for future HIV vaccine development., (Copyright © 2010. Published by Elsevier Ltd.)

- Abstract
Background: Use of the recombinant proteins NefTat and gp120(W61D) formulated with the AS02A adjuvant system was previously shown to protect against AIDS in a rhesus macaque SHIV animal model system., Methods: Eighty-four HIV uninfected human participants were vaccinated intramuscularly at 0, 1, and 3 months and evaluated for safety. Immune responses were analyzed for the presence of vaccine-induced antibody and T lymphocyte responses., Results: The vaccines were safe and well tolerated at all doses. Nef-, Tat-, and gp120-specific binding antibodies were induced in all individuals that received the respective antigen, lasting up to 9 months after the final immunization. Antibodies able to neutralize the T-cell laboratory-adapted strain of HIV-1(W61D) were detected in the majority of vacinees, but did not neutralize primary isolates. Envelope-specific antibody-dependent cell cytoxicity was detected in most of the individuals receiving gp120. Robust and persistent HIV-specific lymphoproliferative responses were detected against all subunit proteins in the majority of immunized participants. As expected, HIV-specific CD8 T-cell responses were not detected., Conclusions: Despite the lack of primary isolate neutralizing antibody induction, the observed high frequency and magnitude of other immune responses warrant further work with this vaccine or vaccine components.

The European Commission (EC) has strong commitments and recognises the need to continue to ensure that HIV/AIDS research efforts receive global attention. The EC is facing this challenge in a global context and has made substantial investments together with European Developing Countries Clinical Trial Partnership (EDCTP) to formulate a program for the accomplishment of a scientific strategic plan promoting the European/African HIV vaccine development approach. The EC and EDCTP has convened a number of meetings by experts in basic and clinical virology, immunology, epidemiology, as well as industrial and regulatory representatives. The remit of the committee of experts was to define (1) objective criteria for selection of HIV candidates; (2) to determine criteria for selection of sites for clinical trials in Europe and Africa. The resulting consensus paper will guide the EC and EDCTP in developing HIV vaccine strategy and recommendations.

- Abstract
Objective: To review and rationalize the liberal use of antenatal betamethasone in the setting of threatened preterm birth., Study Design: A retrospective review was performed using the charts of all patients at Ste-Justine Hospital, Montreal QC, who received antenatal betamethasone between 01 April 1997 and 31 March 1998. Initial treatment consisted of 2 doses of 12 mg IM given 24 hours apart. Repeat doses of 12 mg weekly were administered at the discretion of the treating physician. Optimal antenatal betamethasone therapy was defined as delivery within 1 week of initial treatment, prior to 34 weeks. Aside from number and timing of doses, other factors analyzed included: gestational age at admission and delivery, diagnosis associated with threatened preterm birth (PTB), number of hospital admissions, and delay between re-admission and delivery., Results: Of the 334 patients identified, 82 (25%) received optimal treatment. Of the remaining 252 patients, 204 (81%) received repeat doses. In the repeat dose group, 112 (55%) women delivered after 34 weeks, while 70 of the 92 remaining patients were hospitalized until delivery. The other 22 patients who received serial doses were discharged at least once prior to delivery; of these patients, 8 were re-admitted more than 24 hours pre-delivery (i.e., adequate time for re-treatment), while 14 were not, but only 6 of these were delivered urgently. Thus, a maximum of 60 patients (25% of repeat doses) could potentially have benefited from this approach. Of the 48 patients not receiving repeat doses, 37 (77%) delivered after 34 weeks. Five remained hospitalized, and 6 were discharged prior to delivery and re-admitted (2 patients > 24 hr and 4 patients < 24 hr from delivery). This represented a potential underutilization of betamethasone by 3% (11/334) of the patients, but only 1.8% (6/334) were of less than 32 weeks' gestation., Conclusion: This study demonstrated the difficulty in predicting which of the patients presenting with threatened preterm birth would actually go on to deliver during the window of benefit of antenatal betamethasone therapy. Our desire to permit all premature fetuses to profit from the positive effects of this therapy must be balanced by a reserve in exposing too many to too much. Use of antenatal betamethasone in our unit has significantly decreased since this review.

- Abstract
This study evaluated dual protease inhibitor (PI) regimens containing amprenavir (APV) in PI-naive, HIV-1-infected patients over 48 weeks. Patients were randomized to 800-mg APV combined with 800-mg indinavir (IDV), 750-mg nelfinavir (NFV), or 800-mg saquinavir-soft gel capsule (SGV-SGC), all three times daily without nucleoside reverse transcriptase inhibitors, or APV given alone for 3 weeks and then with 150-mg lamivudine (3TC) and 300-mg zidovudine (ZDV), twice daily. Dual PI therapy demonstrated substantial antiviral activity and was generally safe and well tolerated. Eight patients had virologic failure; 5 were receiving dual PI therapy and 3 were in the APV/3TC/ZDV arm. The protease I50V mutation characteristic of APV resistance was not observed, although other key PI mutations were selected in 4 patients failing therapy, 2 of whom had PI resistance at baseline.

- Abstract
Background: The amprenavir (APV) early or expanded access program was designed to provide open-label APV to patients who would potentially receive benefit beyond that expected from currently available protease inhibitors (PIs) and who were at risk of disease progression before the drug's expected time of regulatory approval., Objective: This study was conducted as part of an early access program to assess the safety profile and tolerability of APV in adults and children (> or =4 years of age) who were either intolerant to or, in the opinion of the patient's physician, virologically failing a previous PI-containing antiretroviral regimen. Specific CD4+ cell count and viral load limits were not imposed by this early access protocol., Methods: This open-label, nonrandomized study was conducted at multiple sites throughout the United States. Adults received APV at a dosage of 1200 mg BID. Patients weighing <50 kg received APV at a dosage of 20 mg/kg BID for the solid formulation or 1.5 mL/kg BID for the liquid formulation., Results: A total of 489 physicians registered for this program; 364 (74.4%) enrolled patients. The safety population of 2217 patients (2048 males [92.4%] and 169 females [7.6%] aged 2 to 74 years) received APV for a median duration of 85 days (range, 2-218 days). Patients in the intent-to-treat population (n = 1427) had extensive experience with antiretroviral therapy. Drug-related treatment-emergent adverse events reported in >3% of patients in the safety population were nausea in 279 patients (12.6%), diarrhea in 197 patients (8.9%), rash in 177 patients (8.0%), vomiting in 148 patients (6.7%), and fatigue in 89 patients (4.0%). Adverse events and laboratory test abnormalities were graded for severity on a scale of 1 to 4 in accordance with AIDS Clinical Trials Group guidelines. Grade 3 treatment-emergent abnormal laboratory values regardless of causality occurring in >3% of patients were neutropenia in 69 of 1887 patients (3.7%; grade 3 toxicity = 500-749/mm3) and elevated triglycerides in 80 of 1593 patients (5.0%; grade 3 toxicity = 751-1200 mg/dL). Most common grade 4 treatment-emergent laboratory abnormalities were elevated serum creatine phosphokinase levels in 36 of 1266 patients (2.8%; grade 4 = >6 times upper normal limit), elevated triglycerides in 39 of 1593 patients (2.4%), and neutropenia in 41 of 1887 patients (2.2%)., Conclusions: The results of this large cohort of patients support the data from the phase II/III clinical development program and suggest that APV has an acceptable safety profile and is generally well tolerated when used in combination with other antiretroviral drugs in a heavily treatment-experienced, heterogeneous patient population.

- Abstract
Objectives: To compare the antiviral activity and safety of a new protease inhibitor, amprenavir (141W94) in combination with lamivudine and zidovudine, versus lamivudine and zidovudine alone in HIV-1 infected, antiretroviral-naive subjects., Design: Subjects (n=232) with a CD4 T cell count of > or =200 cells/mm3, plasma HIV-1 RNA levels of > or =10000 copies/ml, and < or =4 weeks of prior nucleoside antiretroviral therapy, were stratified according to baseline plasma HIV-1 RNA level (10000-30000; 30000-100000; or >100000 copies/ml). Subjects received double-blind treatment with either 1200 mg amprenavir twice daily in combination with lamivudine (150 mg twice daily) and zidovudine (300 mg twice daily) (amprenavir/lamivudine/zidovudine) or matched placebo, lamivudine and zidovudine for 16 weeks. Thereafter, subjects with confirmed plasma HIV-1 RNA levels of > or =400 copies/ml could add open-label amprenavir or switch to other antiretrovirals and continue treatment for up to a minimum of 48 weeks. The primary endpoint of the study was defined as the proportion of subjects with plasma HIV-1 RNA of <400 copies/ml at 48 weeks., Results: At 48 weeks, a significantly greater proportion of amprenavir/lamivudine/zidovudine subjects had plasma HIV-1 RNA levels <400 copies/ml than lamivudine/ zidovudine subjects in the overall population: 41 versus 3% (intent-to-treat missing equals failure analysis) (P<0.001); 93 versus 42% (as-treated analysis) (P<0.001); and within each of the three randomization strata (P<0.001). Subjects on amprenavir/lamivudine/zidovudine experienced longer time to event (permanent discontinuation of randomized therapy or viral rebound) than those on lamivudine/zidovudine (median of 33 versus 13 weeks; P<0.001). A significantly greater incidence of drug-related nausea, vomiting, rash and oral/perioral paresthesia was observed with amprenavir/lamivudine/zidovudine than with lamivudine/zidovudine., Conclusions: Amprenavir, in combination with lamivudine and zidovudine, has potent and durable antiviral activity in antiretroviral-naive subjects over 48 weeks. Amprenavir was safe and generally well tolerated.

- Abstract
To assess the relation between resistance to antiretroviral drugs for treatment of HIV-1 infection and virological response to therapy, results from 12 different studies were re-analysed according to a standard data analysis plan. These studies included nine clinical trials and three observational cohorts. The primary end-point in our analyses was virological failure by week 24. Baseline factors that were investigated as predictors of virological failure were plasma HIV-1 RNA, the number and type of new antiretroviral drugs in the regimen, and viral susceptibility to the drugs in the regimen, determined by genotyping or phenotyping methods. These analyses confirmed the importance of both genotypic and phenotypic drug resistance as predictors of virological failure, whether these factors were analysed separately or adjusted for other baseline confounding factors. In most of the re-analysed studies, the odds of virological failure were reduced by about twofold for each additional drug in the regimen to which the patient's virus was sensitive by genotyping methods, and by about two- to threefold for each additional drug that was sensitive by phenotyping.

- Abstract
To determine whether Epstein-Barr virus (EBV) constitutes a contributing factor in AIDS and, conversely, whether the human immunodeficiency virus (HIV) alters the course of primary EBV infection in a pediatric population, 62 children born to HIV-infected mothers and prospectively followed were evaluated. EBV infection was documented by EBV-specific serology and polymerase chain reaction and by clinical history. HIV infection status was determined according to the Centers for Disease Control and Prevention pediatric classification system. Demographics from HIV-infected and HIV-uninfected children were comparable. The data suggest that HIV-infected children may acquire primary EBV infection earlier in life. The incidence of accompanying splenomegaly or hepatomegaly (or both) around the time of EBV seroconversion was higher among HIV-infected children than among HIV-uninfected children. In contrast, HIV disease progression and HIV-1 RNA load did not seem to be influenced by primary EBV infection.

- Abstract
Background: Human cytomegalovirus (CMV) is a significant cause of morbidity and mortality in transplant recipients. Isolation of CMV from blood leukocytes (CMV viremia) is considered predictive of CMV disease in transplant recipients. Therefore, investigation of methods for the rapid detection of CMV in the blood is important for diagnosis and management of these patients., Objective: To compare three techniques for the diagnosis and monitoring of CMV infection in a pediatric transplant population through the quantitative detection of CMV in peripheral blood leukocytes (PBL)., Methods: Serial blood specimens were obtained for most patients. After separation of the PBL from each specimen, aliquots of the PBL were used for direct detection of CMV antigenemia by immunoperoxidase staining of acetone-fixed cells (CMV-vue kit, INCSTAR), and by immunofluorescence staining of formaldehyde-fixed cells (Complete 1C3 kit, Biosoft Argene). PBL were also inoculated into conventional cell culture tubes and shell vials. Patients' medical records were reviewed to ascertain the clinical significance of the results., Results: A total of 154 specimens obtained from 38 pediatric transplant recipients were evaluated. CMV was detected in 16 specimens obtained from eight patients: 11 specimens were found positive with the CMV-vue kit, 10 with the Complete 1C3 kit, four by conventional culture, and one by the shell vial assay. Seven of the eight patients with CMV-positive PBL had clinical signs and other laboratory evidence of active CMV infection. In general, a high-level antigenemia was demonstrated in the presence of clinical disease, but there were exceptions., Conclusions: The two antigenemia kits were more sensitive than conventional culture and the shell vial assay for the detection of CMV in the blood of pediatric transplant patients. Our results suggest that CMV antigenemia is a sensitive and specific rapid method for the diagnosis and monitoring of CMV infection in our patient population.

- Abstract
Background: Four years ago, we began seeing young children with an unusual, predominantly unilateral, morbilliform and eczematous, self-limited cutaneous eruption. It appeared to correspond to unilateral laterothoracic exanthem (ULE) reported from France and to an eruption described as "a new papular erythema of childhood" in the United States., Objective: We conducted a prospective study of ULE to define its clinical evolution, pathology, and therapy. In addition, we performed epidemiologic and microbiologic investigations in an attempt to determine the cause of ULE., Method: We studied 48 children with ULE. In some patients, blood, urine, stool, as well as skin biopsy specimens were analyzed., Results: ULE is a morbilliform, eczematous eruption that often begins close to the axilla and spreads to become bilateral, although it usually retains a unilateral predominance. Patients' mean age at onset is 24.3 months, with a female predominance (2:1) and mean duration of 5 weeks, followed by spontaneous resolution that may or may not be improved with topical corticosteroids. It is characterized by a unique eccrine lymphocytic infiltration. Although signs of infection were reported by most patients, no one infectious agent was identified. No significant epidemiologic factor was found., Conclusion: ULE, in young children, is a self-limited morbilliform and scarlatiniform eruption that may represent a specific skin reaction to one or more infectious agents.

Pedneault L, Robillard L, Harvey P, and Joncas J
- Abstract
Four commercial enzyme immunoassays (EIA), namely the Behring Enzygnost EIA (BE-EIA), Abbott IMx, Whittaker CMV STAT Test Kit and Diamedix assay, were evaluated for the detection of CMV IgG. The methods were compared as to sensitivity, specificity, positive and negative predictive values, global agreement, ease of performance and, for a small number of specimens, reproducibility. Discordant results were resolved by using the Gull CMV indirect fluorescent antibody (IFA) method. Our data suggest that all four assays were valuable screening tools for the detection of CMV IgG based on their high sensitivity and high negative predictive value. However, differences were noted in the reproducibility level and in the incidence of false-positive, equivocal and nonspecific results regarding certain tests in particular. In our hands, the Abbott IMx and the BE-EIA ranked high in the performance characteristics for a good screening test, yet the Abbott IMx offers the added advantages of being the easiest to perform and having the most rapid turnaround time.

- Abstract
The sensitivity of the polymerase chain reaction (PCR) assay was compared to that of standard Southern blotting (SB) hybridization for detecting the presence of Epstein-Barr virus (EBV) genomes in biopsy samples from 43 patients with a variety of lymphoproliferative disorders. Two pairs of oligonucleotide primers from the first BamHI M and R leftward reading frames (BMLF1 and BRLF1) of EBV were chosen to amplify DNA. The resulting PCR products were analyzed by gel electrophoresis, transfer and hybridization. Restriction enzyme digestion was used to confirm the specificity of the amplified fragment. EBV DNA was found in 38 of 43 patients, as compared with 9 of 43 patients with the Southern technique. No amplified product was detected with other viruses from the Herpes family, nor with human genomic DNA from healthy adults using the same two sets of primers. These results indicate that EBV can be detected in a greater number of lymphoproliferative lesions than previously appreciated. The implications of these findings are discussed.

- Abstract
Epstein-Barr virus (EBV) has been implicated in a variety of central nervous system syndromes. In a few well-studied patients, EBV has been detected by viral isolation or EBV DNA has been found by Southern hybridization analysis. Using polymerase chain reaction, we evaluated brain biopsy specimens from 24 patients for the presence of EBV genomes. EBV DNA was found in brain specimens from 18 patients in whom presence of the virus in the brain was suspected clinically or on the basis of serological tests. Six patients had acquired immunodeficiency syndrome; 2 were kidney transplant recipients. Brain specimens from 4 patients with encephalitis due to other herpes group viruses and from a patient with metabolic encephalopathy were negative for EBV DNA as determined by polymerase chain reaction. The findings indicate a need to evaluate the role of EBV in diverse neurological syndromes, especially those occurring in immunodeficient hosts.

- Abstract
CV 205-502, a new long-acting nonergot dopamine agonist, was given to 15 patients (6 women and 9 men) with PRL-secreting pituitary macroadenomas. The compound was administered in a single daily dose for a period of 6-12 months. The treatment resulted in normalization of plasma PRL levels (less than or equal to 20 micrograms/L) in 5 of 6 women at a mean dose of 135 micrograms (range, 75-300 micrograms) and in 6 of 9 men at a mean dose of 192 micrograms (range, 75-300 micrograms). Among patients for whom computed tomographic scans were available before and after at least 6 months of therapy, definite tumor shrinkage occurred in 6 of 7 patients. Libido was improved in 5 of 6 women and in 6 of 8 men, galactorrhea disappeared in all cases (3 women and 1 man) and menses resumed in 3 of 5 women. Plasma testosterone rose to normal levels in 3 of 6 men who were not receiving testosterone injections. The PRL response to TRH was blunted in 4 of 6 patients with normalized basal PRL. Serum total cholesterol was reduced by CV 205-502 treatment in women from 5.35 +/- 0.49 to 4.63 +/- 0.51 mmol/L (P = 0.031) and in men from 5.93 +/- 0.89 to 5.28 +/- 0.82 mmol/L (P = 0.045). Side-effects included mainly headache, nausea, and dizziness. One side-effect or more occurred transiently and with mild intensity in 14 patients. No patient discontinued the therapy because of side-effects. In conclusion, CV 205-502 appears to be a safe and valuable compound in the treatment of patients with PRL-secreting macroadenomas.
