| antibody to pneumocystis carinii protects rats and mice from developing pneumonia. | well-proven mouse and rat models were used to show that polyclonal antisera to pneumocystis carinii protect against p. carinii pneumonia. antibodies were obtained from animals that were allowed to recover from severe p. carinii pneumonia after immunosuppression had been stopped and which then were given a booster injection of p. carinii from the same animal species. mice immunosuppressed with corticosteroids or antibodies to l3t4+ lymphocytes (which are comparable to cd4 cells of humans) and tra ... | 1998 | 9455884 |
| expression, structure, and location of epitopes of the major surface glycoprotein of pneumocystis carinii f. sp. carinii. | the major surface glycoprotein (msg) of pneumocystis carinii f. sp. carinii consists of a heterogeneous family of proteins that are encoded by approximately 100 unique genes. a genomic expression library was screened with a panel of msg-specific monoclonal antibodies (mabs) to identify conserved and rare epitopes. all of the antibodies reacted with epitopes that are encoded within the 5' end of msg. the results from the expression screening identified antibodies that recognize highly conserved, ... | 1998 | 9455880 |
| identification of a putative precursor to the major surface glycoprotein of pneumocystis carinii. | the major surface glycoprotein (msg) of pneumocystis carinii f. sp. carinii is a family of proteins encoded by a family of heterogeneous genes. messenger rnas encoding different msgs each begin with the same 365-bp sequence, called the upstream conserved sequence (ucs), which is in frame with the contiguous msg sequence. the ucs contains several potential start sites for translation. to determine if translation of msg mrnas begins in the ucs, polyclonal antiserum was raised against the 123-amino ... | 1998 | 9453635 |
| the needs of asians and pacific islanders living with hiv in new york city. | this article familiarizes the reader with aids among asians and pacific islanders (a&pis) in new york city. the first section describes the epidemiology of aids among a&pis in the united states and in new york city. in the united states 4,131 a&pis have been diagnosed with aids. the age at diagnosis in the united states has been relatively stable over the past decade, although the proportion of diagnoses represented by older a&pis (aged 40 to 49) has been increasing in new york city. the proport ... | 1997 | 9451477 |
| serological studies on porcine pneumocystis carinii pneumonia: kinetics of the antibody titers in swine herds and the association of porcine reproductive and respiratory syndrome virus infection. | serological titers to pneumocystis carinii (pc) and porcine reproductive and respiratory syndrome virus (prrsv) were measured on a herd with epidemic pc pneumonia (case herd) and two comparison herds, by an indirect fluorescent-antibody technique. in the case herd, the geometric mean titer (gmt) for pc were 1:80 in pigs 1 week old, 1:10 in pigs 5 weeks old, and 1:80 to 1:190 in pigs over 6 weeks old. gmts for prrsv were > 1:145 in most of age groups over 7 weeks old. in comparison herds, pc and ... | 1997 | 9450249 |

| pulmonary high-resolution computed tomography versus gallium scintigraphy: diagnostic utility in the diagnosis of patients with aids who have chest symptoms and normal or equivocal chest radiographs. | fifty-six consecutive symptomatic patients with aids referred for gallium scintigraphy were prospectively studied with chest high-resolution computed tomography (hrct). results of gallium and hrct were correlated with findings of bronchoscopy or clinical follow-up for 1 month from time of discharge. twenty-two patients were eventually diagnosed with at least one of the following: pneumocystis carinii, cytomegalovirus, mycobacterium avium complex, bacteria, kaposi's sarcoma, or lymphocytic inters ... | 1998 | 9440841 |
| the cost-effectiveness of preventing aids-related opportunistic infections. | multiple options are now available for prophylaxis of opportunistic infections related to the acquired immunodeficiency syndrome (aids). however, because of differences in incidence rates as well as drug efficacy, toxicity, and costs, the role of different types of prophylaxis remains uncertain. | 1998 | 9440663 |
| 2,5-bis[4-(n-alkylamidino)phenyl]furans as anti-pneumocystis carinii agents. | the syntheses of 12 new 2,5-bis[4-(n-alkylamidino)phenyl]furans are reported. the interaction of these dicationic furans with poly(da-dt) and with the duplex oligomer d(cgcgaattcgcg)2 was determined by tm measurements, and the effectiveness of these compounds against the immunosuppressed rat model of pneumocystis carinii was evaluated. at the screening dose of 10 mumol/kg, 9 of the 14 n-alkylamidino furans described here are more active than the parent compound 1. substitution of an alkyl group ... | 1998 | 9438029 |
| pneumocystis carinii induces icam-1 expression in lung epithelial cells through a tnf-alpha-mediated mechanism. | inflammatory cell recruitment contributes to respiratory impairment during pneumocystis carinii pneumonia. we evaluated expression of intercellular adhesion molecule-1 (icam-1), a key participant in leukocyte accumulation, in rats with p. carinii pneumonia. immunostaining for icam-1 was most marked on bronchiolar epithelium but was also evident on type ii pneumocytes, endothelium, and macrophages. lung from normal and dexamethasone-treated uninfected animals exhibited markedly less icam-1. we hy ... | 1997 | 9435563 |
| disseminated infection with bacillus calmette-guerin in a child with advanced hiv disease. | an 8-month-old boy with vertically acquired hiv-infection who developed a disseminated bcg infection is described. the patient had been immunized at birth with bcg. in spite of a normal cd-4 lymphocyte count, he suffered from fever, anaemia and failure to thrive. bcg was isolated by culture from csf, bone marrow and peripheral blood. anti-tuberculous treatment initially seemed successful, but shortly after, the patient died from pneumocystis carinii pneumonia. in symptomatic hiv-infected childre ... | 1997 | 9435049 |

| pre-aids era isolates of pneumocystis carinii f. sp. hominis: high genotype similarity with contemporary isolates. | isolates of pneumocystis carinii f. sp. hominis were examined from six individuals who died of p. carinii pneumonia between 1968 and 1981 and who had underlying immunodeficiencies which were not due to human immunodeficiency virus infection. dna sequence variation was analyzed in the genes encoding the mitochondrial large subunit rrna (mt lsu rrna), the internal transcribed spacer (its) regions of the nuclear rrna, the arom locus, and the mitochondrial small subunit rrna. no major variations wer ... | 1998 | 9431927 |
| partial sequence of the rrna operon of pneumocystis carinii isolates from puerto rico. | several reports indicate geographic variation of isolates of pneumocystis carinii hominis. we have sequenced the internal transcribed spacer (its) region and large subunit group i intron of rrna genes from p. carinii dna obtained from two patients from puerto rico. both can be subclassified as type ii, according to the sequence of the its region. a system capable of identifying individual isolates will be an essential tool for epidemiological studies of the organism. the amplification of dna fro ... | 1997 | 9431562 |
| characteristics of human immunodeficiency virus-infected children at the time of death: an experience in the 1990s. | to describe the changes in the characteristics of human immunodeficiency virus (hiv)-related deaths in children with perinatally acquired infection. | 1997 | 9427460 |
| pleural disease and acquired immune deficiency syndrome. | patients with acquired immune deficiency syndrome (aids) do not frequently have pleural complications. however, pneumothorax is a troublesome complication of patients with aids. at some medical centres, more than 50% of patients with spontaneous pneumothorax have aids. most patients with spontaneous pneumothorax and aids have pneumocystis carinii infection and necrotic subpleural blebs. the pneumothoraces in these patients usually cannot be managed with tube thoracostomy alone. patients who do n ... | 1997 | 9426107 |
| [cystic form of pneumocystis carinii pneumonia]. | in rare instances pneumocystis carinii pneumonia (pcp) can occur in a cystic form, characterized by an acute course. the correct diagnosis is often missed. an analysis of a large cohort of patients with pcp was undertaken to determine the incidence and clinical manifestations of this form of the disease. | 1997 | 9424421 |
| activated pulmonary macrophages are insufficient for resistance against pneumocystis carinii. | cd4+ t cells are pivotal for elimination of pneumocystis carinii from infected lungs, and alveolar macrophages are considered the main effector cells clearing the infected host of p. carinii organisms. to investigate this issue, several mutant mouse strains were used in a previously established experimental setup which facilitates natural acquisition of disease through inhalation of airborne fungal organisms. mutant mice deficient in major histocompatibility complex class ii molecules (a beta(-/ ... | 1998 | 9423872 |

| diagnostic strategies in pneumocystis carinii pneumonia. | pneumocystis carinii (p. carinii) remains a major pulmonary pathogen for the immunocompromised patient. in hiv infected patients, p. carinii represents the most commonly diagnosed cause of pneumonia. in the aids patient, empiric therapy based on clinical presentation has its proponents. however, this approach has been associated with a worse overall prognosis for the at risk patient. because p. carinii can not be cultured, specific identification relies on examining respiratory specimens ranging ... | 1998 | 9405333 |
| dapsone for pneumocystis carinii prophylaxis in children undergoing bone marrow transplantation. | children who undergo bone marrow transplantation (bmt) are at risk for pneumocystis carinii pneumonia (pcp). prophylaxis using trimethoprim/sulfamethoxazole (tmp/smx) is highly effective but the incidence of adverse drug reactions is significant. we retrospectively reviewed 33 pediatric bmt (25 allogeneic and eight autologous) in whom dapsone was used for pcp prophylaxis because patients were unable to receive tmp/smx. dapsone was administered at 50 mg/m2 p.o. once a week from engraftment to 180 ... | 1997 | 9404930 |
| intensified therapy for infants with acute lymphoblastic leukemia: results from the dana-farber cancer institute consortium. | infants with acute lymphoblastic leukemia (all) have a very poor prognosis. since 1985, we have intensified therapy for infants with all by including a month of high dose multiagent chemotherapy after remission induction. | 1997 | 9404706 |
| paediatric hiv update. | less than half of the paediatric hiv infections recorded in australia have resulted from perinatal transmission, but in recent years this has been the predominant mode of infection. there are 136 infants who are known to have been exposed perinatally to hiv in australia: 49 of these are infected. caesarean section is thought now not to reduce the risk of perinatal transmission (pnt); rather, the risk increases with duration of membrane rupture and rises rapidly after 4 h of membrane rupture. how ... | 1997 | 9401877 |
| typing of pneumocystis carinii f. sp. hominis by single-strand conformation polymorphism of four genomic regions. | to better investigate pneumocystis carinii f. sp. hominis epidemiology, we have developed a molecular typing method. because of the limited genetic variability of the p. carinii hominis genome, a multitarget approach was used. four variable regions of the genome were amplified by pcr, polymorphism in each region was assessed by the single-strand conformation polymorphism (sscp) technique, and the results for the four regions of each patient were combined. bronchoalveolar lavage specimens collect ... | 1997 | 9399499 |
| a pneumocystis carinii group i intron ribozyme that does not require 2' oh groups on its 5' exon mimic for binding to the catalytic core. | the recent increase in the population of immunocompromised patients has led to an insurgence of opportunistic human fungal infections. the lack of effective treatments against some of these pathogens makes it important to develop new therapeutic strategies. one such strategy is to target key rnas with antisense compounds. we report the development of a model system for studying the potential for antisense targeting of group i self-splicing introns in fungal pathogens. the group i intron from the ... | 1997 | 9398259 |
| pulmonary complications after bone marrow transplantation: high-resolution ct and pathologic findings. | a wide variety of pulmonary complications occur in bone marrow transplant (bmt) recipients and are a major cause of morbidity and death. high-resolution computed tomography (ct) is excellent in the detection of pulmonary abnormalities, but these findings are generally nonspecific. however, the different complications, which reflect the immunologic status of the patients, occur in three phases. this pattern can be used to interpret ct scans. the neutropenic phase (up to 3 weeks after bmt) is char ... | 1997 | 9397451 |
| short- and long-term efficacy of cyclosporin administration in patients with acute severe ulcerative colitis. belgian ibd group. | cyclosporin (csa) has been proposed in the management of patients with acute ulcerative colitis (uc) in whom standard therapy failed and who were candidates for colectomy. seven academic hospitals contributed to this retrospective study that included 29 patients (median age: 33 y. (15-74 y.); 12 females and 17 males). the median duration of the disease was 4 y. (0.3 to 33 y.). before initiating csa, patients were unresponsive to treatment including i.v. corticosteroids (n = 29), 5-asa or salazop ... | 1997 | 9396174 |
| prohibitin, a putative negative control element present in pneumocystis carinii. | little is known about the molecules involved in the regulation of pneumocystis carinii replication and development in vitro and in vivo. we describe in this report the identification of a p. carinii gene encoding the p. carinii prohibitin protein. in mammals, the prohibitin gene product has been shown to negatively regulate cell proliferation. a cdna clone encoding the p. carinii prohibitin gene was isolated from a p. carinii cdna library and identified on the basis of amino acid sequence homolo ... | 1997 | 9393805 |
| protection against pneumocystis carinii pneumonia by antibodies generated from either t helper 1 or t helper 2 responses. | to determine whether different antibody isotypes associated with t helper 1 (th1) or th2 responses are protective against pneumocystis carinii, mice with disrupted interleukin 4 genes (il-4(-/-) mice) or gamma interferon genes (ifn-gamma(-/-) mice) along with wild-type c57bl/6 mice were immunized intratracheally against p. carinii, depleted of t cells in vivo by use of monoclonal antibodies, and rechallenged intratracheally with 10(7) viable p. carinii organisms. nearly all immunized mice resolv ... | 1997 | 9393795 |

| pulmonary aspergillosis in acquired immune deficiency syndrome: autopsy study of an emerging pulmonary complication of human immunodeficiency virus infection. | pulmonary aspergillosis has recently been described as an emerging infection in patients with acquired immune deficiency syndrome (aids), but the pathological changes have not been well documented. in this autopsy study, 17 cases of aids-related pulmonary aspergillosis were identified from the files of two institutions. with the exception of hypersensitivity reactions, the entire spectrum of pulmonary aspergillosis was represented. thirteen patients exhibited acute invasive aspergillosis, and se ... | 1997 | 9385932 |
| causes of death of hiv-infected persons in ottawa, ontario, 1984-1995. | acquired immunodeficiency syndrome (aids) has become a leading cause of death of young men in the united states. with the introduction of prophylaxes and antiretrovirals for opportunistic infection, there have been significant changes in the clinical history of human immunodeficiency virus (hiv) infection. | 1997 | 9382662 |
| trends in incidence of aids illnesses in australia from 1983 to 1994: the australian aids cohort. | to assess time trends in incidence of aids illnesses in australia, a retrospective cohort of people diagnosed with aids from january 1, 1983 to december 31, 1994 in three hiv medicine units in sydney, melbourne, and perth was established. data on initial and subsequent aids illnesses were available for 2580 aids cases, or 45% of australian aids notifications over the study period. males represented 97.2% of the cohort, and hiv exposure category was homosexual contact for 89.9%. subcohorts were f ... | 1997 | 9377123 |
| [value of high-resolution ct of the lungs in acute pulmonary symptoms of patients with hiv infections]. | purpose: the purpose of this study was to assess the clinical value of hrct of the lung in patients with known hiv-infection and acute lung disease. in a prospective study a hrct was performed in 31 patients infected with the hiv-1 virus, mainly stage c (cdc), who had acute pulmonary symptoms. precondition for the hrct examination was a normal or non-specific chest radiograph. a provoked sputum as well as bronchoscopy with bronchoalveolar lavage and/or transbronchial biopsy were performed concur ... | 1997 | 9376549 |
| analysis of cytokine mrna profiles in the lungs of pneumocystis carinii-infected mice. | severe combined immunodeficient (scid) mice lack functional cd4+ lymphocytes, and therefore develop life-threatening pneumocystis carinii infection. however, when scid mice are immunologically reconstituted with spleen cells, including cd4+ cells, a protective inflammatory response is mounted against the organism. to determine whether these lymphocytes induce elevated cytokine mrna levels in response to p. carinii infection, steady-state levels of cytokine mrnas were measured in the lungs of bot ... | 1997 | 9376124 |
| pneumocystis carinii infection of the conjunctiva in a patient with acquired immune deficiency syndrome. | ocular disease, especially the development of choroidal lesions, is a known extrapulmonary manifestation of pneumocystis carinii infection in the acquired immune deficiency syndrome (aids). to our knowledge, conjunctival involvement due to p. carinii has not been described previously. | 1997 | 9373116 |
