Incidence, etiology, and outcome of hospital-acquired pneumonia in patients with acute exacerbation of fibrotic idiopathic interstitial pneumonia. Respir Investig 2024; 62:488-493. [PMID: 38579411 DOI: 10.1016/j.resinv.2024.03.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Revised: 03/07/2024] [Accepted: 03/15/2024] [Indexed: 04/07/2024]
Abstract
BACKGROUND Acute exacerbations (AEs) of fibrotic idiopathic interstitial pneumonia (fIIP) that require hospitalization occur in some patients. During hospitalization, these patients can develop hospital-acquired pneumonia (HAP), a common hospital-acquired infection with a high mortality rate. However, the characteristics of HAP in AE-fIIP remain unknown. The purpose of this study was to determine the incidence, causative pathogens, and outcomes of HAP in patients with AE-fIIP. METHODS The medical records of consecutive patients who were hospitalized with AE-fIIP from January 2008 to December 2019 were analyzed for the incidence, causative pathogen, and survival of HAP. The records of patients with an obvious infection-triggered AE were excluded from analysis. RESULTS There were 128 patients with AE-fIIP (89 with idiopathic pulmonary fibrosis [IPF] and 39 with non-IPF fIIP) who were hospitalized a total of 155 times (111 with IPF and 44 with non-IPF fIIP). HAP occurred in 49 patients (40 with IPF and 9 with non-IPF fIIP). The incidence and the in-hospital mortality rates of HAP in patients with AE-fIIP were high, at 32.2% and 48.9%, respectively. Corynebacterium spp. was the most common causative pathogen, which was followed by human cytomegalovirus (HCMV). CONCLUSIONS The incidence and the in-hospital mortality rates of HAP in patients with AE-fIIP are high. To improve their survival, patients with fIIP who had AEs and HAP should receive prompt empirical treatment for possible infections with Corynebacterium spp. and testing for HCMV.

Abstract
To investigate the risk factors for CMV infection and to clarify the cut-off count of CMV pp65 antigenemia predicting clinical symptoms related to CMV infection in patients with rheumatic disease. We retrospectively analyzed 261 patients with rheumatic disease who were treated with immunosuppressive therapy. CMV infection was defined as positive > 1 CMV-positive cell per two slides (CMV pp65 antigenemia C10/C11). Patients with CMV infection were divided into two groups based on the presence of antiviral treatment for CMV disease. We determined a cut-off value of CMV-positive cells for the diagnosis of CMV disease. CMV infection was observed in 141 cases (54%). In a multivariate analysis, CMV infection was associated with three following factors: Age > 60 years (OR 1.87 [95% CI 1.04-3.36]); lymphocyte counts < 1000/μL (OR 3.34 [95% CI 1.88-6.05]); steroid pulse therapy (OR 2.60 [95% CI 1.27-5.55]). The cut-off level of CMV pp65 antigenemia indicating CMV disease was five positive cells average two slides by using receiver operating characteristic curve analysis (AUC 0.95, sensitivity 0.94, specificity 0.80). Age > 60 years, lymphocytopenia (< 1000/μL) and steroid pulse therapy are risk factors of CMV infection. We recommend that CMV pp65 antigenemia of > 5 cells average two slides (C10/C11) in patients with rheumatic disease should be the treated with antiviral drugs.

Abstract
INTRODUCTION This study aimed to examine the factors associated with cytomegalovirus (CMV) antigenemia and the time of onset of CMV antigenemia among patients with rheumatic diseases. METHODS A single-center, retrospective, observational study was conducted in our institution from January 2009 to December 2017. This study included patients with rheumatic diseases who had at least one CMV antigen measurement. Multivariate analysis and receiver operating characteristic analysis was performed. RESULTS A total of 249 patients underwent CMV antigenemia assay, and 84 (33.7%) patients tested positive. When the association between CMV antigenemia and possible associated factors was investigated, multivariate analysis showed that daily steroid dose increased the odds of having CMV [odds ratio 16.25, 95% confidence interval (CI), 5.360-49.253]. In this study, the cutoff value of daily steroid dose found in this study (0.45 mg/kg/day) was reasonable in clinical practice, and the area under the curve of the steroid dose was 0.838 [95% CI 0.781-0.882], which was the largest of the known indicators. Moreover, the median time from the start of immunosuppressive therapy to the onset of CMV antigenemia was 30 (interquartile range, 21-44) days, and most of the daily steroid users (85.7%) developed CMV antigenemia within 60 days. CONCLUSIONS The daily steroid dose is the most important factor associated with CMV antigenemia. Therefore, monitoring and treatment strategies based on the steroid dose, especially in the initial 2 months, are important.

Abstract
Dermatomyositis (DM) patients are known to have various infectious complications, such as cytomegalovirus (CMV) reactivation, due to immune dysfunction caused by DM itself and immunosuppressants used for treatment. Although CMV reactivation has been known to be a major cause of mortality in immunocompromised hosts, there has not been sufficient study of CMV reactivation in DM patients. The objective of this study was to examine the frequency of CMV reactivation in DM patients and to investigate risk factors potentially associated with development of CMV reactivation. We analyzed 52 Japanese DM patients, and CMV reactivation was observed in 21 (40.4%). The mean duration from the initiation of prednisolone (PSL) to the diagnosis of CMV reactivation was 6.1 ± 0.5 weeks. The total amount of oral PSL before the diagnosis of CMV reactivation was 2000.3 ± 169.3 mg. Using a univariate analysis, we found that the prevalence of interstitial lung disease and the frequency of diabetes mellitus complications in DM patients with CMV reactivation was significantly higher than that in DM patients without CMV. We identified that low lymphocytes (<900/μL) in DM patients was significantly associated with developing CMV reactivation. The use of immunosuppressants, including tacrolimus, cyclosporin and/or i.v. cyclophosphamide, was significantly associated with CMV reactivation in DM patients. Using a multivariate analysis, low lymphocytes at the time of DM diagnosis was found to be a risk factor for CMV reactivation. In addition, there was a tendency for diabetes mellitus to be a risk factor for CMV reactivation in DM patients. There was no difference in the prognosis for those with or without CMV reactivation in this study. These results suggest that in the DM patients with risk factors such as low lymphocytes and diabetes mellitus complications, regularly monitoring CMV reactivation and adequate treatment with antiviral agents may be necessary to prevent a poor prognosis.

Abstract
Objective: To assess risk factors for cytomegalovirus (CMV) disease with CMV re-activation in patients with rheumatic disease.Methods: The clinical data of consecutive patients with rheumatic disease who experienced CMV re-activation were examined. We evaluated the difference in various baseline factors at the first detection of CMV pp65 antigenemia on the development of CMV disease using logistic regression models. The changes of laboratory data in the 4 weeks before CMV re-activation were also assessed.Results: We identified 80 patients (median age [interquartile range] = 65.0 years [51.5-74.0]) with CMV re-activation. Oral candidiasis, serum albumin ≤30 g/L, and CMV pp65-positive cell count >5.6/105 polymorphonuclear leukocyte cells were found to be associated with CMV disease (odds ratio [OR] [95% CI] = 9.99 [2.02-49.50], 11.4 [1.94-67.40] and 6.80 [1.63-28.30], respectively). Moreover, decreases in serum albumin level and blood lymphocyte count in the 4 weeks before CMV re-activation also predicted CMV disease (OR [95% CI] = 2.02 [1.07-3.8] and 1.96 [1.09-3.54], respectively).Conclusion: In CMV re-activation patients with rheumatic disease, the presence of oral candidiasis, high CMV pp65 positive cell count, and hypoalbuminemia are possible risk factors for CMV disease.

Abstract
Introduction: In contrast to organ transplantation, few studies correlate the monitoring of
pp65 antigenemia with a diagnosis of cytomegalovirus (CMV) in patients with
systemic lupus erythematosus (SLE). Objective: To highlight the importance of CMV outside transplantation, we monitored pp65
antigenemia in a series of SLE patients. Methods: From March 2015 to March 2016, SLE patients presenting kidney involvement,
fever, and an unclear infection at hospital admission were monitored through
pp65 antigenemia. The pp65 antigenemia assay, revealed by
immunofluorescence, was correlated with clinical and laboratory
findings. Results: We included 19 patients with a suspected unclear infection. A positivity for
pp65 antigenemia was found in seven patients (36.8%). The mean age was 33.5
± 11.2 years, 16 (84%) were females, and 16 (84%) were black. Lymphopenia,
anemia, and higher scores of SLEDAI were significantly more common in
pp65-positive patients. Five patients received antiviral therapy with
ganciclovir. Although receiving specific CMV treatment, one patient died
because of suspected CMV disease. Conclusions: Pp65 antigenemia might be relevant in SLE patients, and studies with a
greater number of patients are needed in order to establish sensitivity and
specificity of pp65 antigenemia in different clinical contexts of SLE
patients.

Abstract
Background Cytomegalovirus (CMV) is the main infectious agent causative of morbidity and mortality in transplant recipients. This study aimed to describe the occurrence and clinical features of CMV infection, and the optimum antigenemia assay cutoff associated with symptomatic infection. Materials and Methods This was a cohort study that investigated 87 patients undergoing renal transplantation. The patients were monitored with the CMV antigenemia assay performed weekly for the first 3 months post-transplantation and subsequently, when CMV infection was suspected clinically. Results CMV infection was observed in 63.2% (55/87) of the recipients during the follow-up. Of the 65 episodes observed, 75% (49/65) occurred until 100 days after transplantation (D+100) and 25% (16/65) after D+100 with a median of 60 days. CMV infection was associated with age of the transplant recipients (P = 0.001) and use of deceased donor organ (P = 0.009). There were asymptomatic (34%) and symptomatic (66%) episodes of CMV infection, in which diarrhea was the most common symptom (22.6%), followed by elevated creatinine levels (14.5%), fever (12.9%) and leukopenia (10.5%). The optimum cutoff point associated with symptomatic infection was 5 positive cells/200,000 leukocytes (area under the curve = 0.87, positive predictive value = 88% and negative predictive value= 71%). Conclusions The high occurrence and the risk factors for CMV infection such as the age of recipients, the number of positive cells in the antigenemia assay, and use of a deceased donor organ should be considered for appropriate monitoring and management of kidney recipients during the post-transplant period.

Abstract
Cytomegalovirus infection is one of most frequent infectious complications after renal transplantation, and can be classified as primo-infection, when the transmission occurs through the graft, or reactivation, when the recipient is cytomegalovirus seropositive. After transplantation, cytomegalovirus can appear as an infection, when the patient presents with evidence of viral replication without symptoms or disease, which has two clinical spectra: typical viral syndrome or invasive disease, which is a less common form. Their effects can be classified as direct, while the disease is developed, or indirect, with an increase of acute rejection and chronic allograft dysfunction risks. Diagnosis must be made based on viremia by one of the standardized methods: antigenemia or PCR, which is more sensitive. The risk factors related to infection after transplantation are the serologic matching (positive donor and negative recipient) and anti-lymphocyte antibody drugs. One of the strategies to reduce risk of disease should be chosen for patients at high risk: preemptive treatment or universal prophylaxis. Recent clinical research has described ganciclovir resistance as an emergent problem in management of cytomegalovirus infection. Two types of mutation that cause resistance were described: UL97 (most frequent) and UL54. Today, sophisticated methods of immunologic monitoring to detect specific T-cell clones against cytomegalovirus are used in clinical practice to improve the management of high-risk patients after renal transplantation.

Abstract
Little is known about the risk factors for long-term poor outcome in pediatric renal transplantation. Between 1973 and 2010, 111 renal transplants (92 living donations) were performed in 104 children (56 males, mean age, 12.5 yr) at the Social Insurance Chukyo Hospital, and followed-up for a mean period of 13.6 yr. The patient survival at 1, 5, 10, 15, 20 (living- and deceased-donor transplants), and 30 yr (living-donor transplants only) was 98.1%, 92.8%, 87.8%, 84.9%, 82.6%, and 79.3%. The graft survival at 1, 5, 10, 15, 20, and 30 yr was 92.0%, 77.3%, 58.4%, 50.8%, 38.5%, and 33.3%. The most common cause of graft loss was CAI, AR, death with functioning, recurrent primary disease, ATN, and malignancy. Donor gender, ATN, malignancy/cardiovascular events, and eras affected patient survival. AR and CAI were the risk factors for graft loss. The evolved immunosuppression protocols improved the outcome by reducing AR episodes and ATN but not CAI, suggesting CAI as the major risk factor for graft loss. CAI was correlated with AR episodes, CMV infection, and post-transplant hypertension. Strategies for preventing the risk factors for malignancy/cardiovascular events and CAI, including hypertension/infection, are crucial for better outcomes.

Abstract
Common variable immunodeficiency (CVID) is the most frequent clinically relevant primary immunodeficiency and shows enormous heterogeneity in clinical presentation. Despite clinical immunodeficiency, opportunistic infections are not a typical manifestation of CVID. A retrospective study of 32 patients followed up for 335 patient-years was performed to determine the frequency of cytomegalovirus (CMV) disease. Symptomatic CMV infection was documented in 3 CVID patients. Patients No. 1 and 2 suffered from CMV pneumonia, with complications due to atypical mycobacteriosis in patient No. 1. Patient No. 3 suffered from CMV enteritis. A history of cancer and chronic hepatitis C infection (patient No. 1), immunosuppressive therapy for interstitial lung disease (patient No. 2) and serious enteropathy complicated with malnutrition (patient No. 3) may have contributed to the complications despite only mild abnormalities in T-cell subpopulations. The direct detection of CMV in bronchoalveolar lavage, stool or tissue samples was the most beneficial diagnostic laboratory method, whereas the detection of CMV DNA in blood did not produce positive results. Adequate treatment of CMV disease led to significant clinical improvement in all 3 patients. The frequency of CMV disease appears to be higher than previously described. In our experience, the probability of opportunistic infections in CVID patients increases with secondary comorbidities and their management.

The effects of preemptive therapy using a very low threshold of pp65 antigenemia to prevent cytomegalovirus disease in kidney transplant recipients: a single-center experience. Transplant Proc 2013; 45:182-4. [PMID: 23375295 DOI: 10.1016/j.transproceed.2012.07.144] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2012] [Accepted: 07/27/2012] [Indexed: 01/07/2023]
Abstract
BACKGROUND Preemptive therapy is a valid option for cytomegalovirus (CMV) disease prevention in kidney transplant recipients. However, there are controversies regarding the appropriate threshold value to be reached before starting antiviral drugs. The aim of this study was to evaluate the benefit of a low threshold of the CMV pp65 antigenemia test as a guide to initiate the therapy. METHODS We performed a prospective study on 47 consecutive kidney recipients. The CMV pp65 antigenemia test was performed over 6 months posttransplantation; patients who displayed ≥ 2/200,000 CMV antigen-positive leukocytes were treated for 2 months with valgancyclovir (450 mg twice a day). RESULTS Twenty-five patients developed CMV infections, which were initially diagnosed at 55 ± 25 days posttransplantation. The number of CMV antigen-positive cells/200,000 leukocytes on the first positive test was 17 ± 22. The test first became negative at 17 ± 8 days after the diagnosis. A positive correlation was observed between the number of CMV antigen-positive cells and the time to obtain the first negative test (P = .01). At the end of follow-up (35.3 ± 16.4 months), none of the patients had developed CMV syndrome. Among the CMV-positive recipients, the creatinine levels showed no differences from the values before the CMV infection. No difference in creatinine levels was noted between CMV infection positive versus negative patients. CONCLUSION Our data suggested that a CMV antigenemia titer ≥ 2/200.000 leucocytes can be considered to be an appropriate threshold to start anti-CMV preemptive therapy.

Abstract
Cytomegalovirus (CMV) continues to be one of the most common infections after solid-organ transplantation, resulting in significant morbidity, graft loss, and adverse outcomes. Management of CMV varies considerably among transplant centers but has been become more standardized by publication of consensus guidelines by the Infectious Diseases Section of The Transplantation Society. An international panel of experts was reconvened in October 2012 to revise and expand evidence and expert opinion-based consensus guidelines on CMV management, including diagnostics, immunology, prevention, treatment, drug resistance, and pediatric issues. The following report summarizes the recommendations.

Abstract
Cytomegalovirus (CMV) is the most common infection after organ transplantation and has a major impact on morbidity, mortality and graft survival. Optimal prevention, diagnosis and treatment of active CMV infection enhance transplant outcomes, and are the focus of this section. Methods to prevent CMV include universal prophylaxis and preemptive therapy; each has its merits, and will be compared and contrasted. Diagnostics have improved substantially in recent years, both in type and quality, allowing for more accurate and savvy treatment; advances in diagnostics include the development of an international standard, which should allow comparison of results across different methodologies, and assays for cellular immune function against CMV. Therapy primarily involves ganciclovir, now rendered more versatile by data suggesting oral therapy with valganciclovir is not inferior to intravenous therapy with ganciclovir. Treatment of resistant virus remains problematic, but is enhanced by the availability of multiple novel therapeutic agents.

Abstract
Human cytomegalovirus (HCMV) is an important cause of morbidity and mortality in immunosuppressed transplant recipients. Isolation of HCMV from peripheral blood leukocytes (PBLs) is considered a reliable marker of disseminated HCMV infection. HCMV pp65 antigenemia is widely used for monitoring CMV infection and guiding preemptive therapy. The aim of this study was to compare pp65 antigenemia with culture technique for detection of HCMV in PBLs among kidney transplant patients and also to determine the threshold value of significant pp65 antigenemiat. Fifty-one peripheral blood samples from post-renal transplant patients collected during August 2009 to March 2011 were processed for pp65 antigenemia assay. These were also tested for isolation of the virus by inoculation into human corneal fibroblast cells. The results of pp65 antigenemia and culture were compared to determine the clinical significance of pp65 antigenemia. HCMV was isolated in 21 cases. On comparing the pp65 antigenemia results with that of the viral isolation, a mean of 23 cells was determined to yield a positive isolation of HCMV. The values of pp65 antigenemia and isolation results were correlated (paired t-test, P = 0.0029). A pp65 count of 23 and above was considered significant in our clinical settings since we found that these clinical specimens yield positive culture result.

Abstract
qPCR and pp65 antigenemia assays are used to monitor CMV infection in renal transplant recipients, but correlation of assays in a pediatric population has not been evaluated. Paired CMV real-time qPCR and pp65 antigenemia tests from 882 blood samples collected from 115 pediatric renal transplant recipients were analyzed in this retrospective cohort study for the strength of association and clinical correlates. The assays correlated well in detecting infection (κ = 0.61). Higher qPCR values were demonstrated with increasing levels of antigenemia (p < 0.01). Discordant test results were associated with antiviral treatment (OR 4.33, p < 0.01) and low-level viremia, with odds of concordance increasing at higher qPCR values (OR 3.67, p < 0.01), and no discordance occurring above 8500 genomic equivalents/mL. Among discordant samples, neither test preceded the other in detecting initial infection or in returning to negative while on treatment. Only two cases of disease occurred during the two-yr study period. With strong agreement in the detection of CMV infection, either qPCR or pp65 antigenemia assays can be used effectively for monitoring pediatric renal transplant patients for both detection and resolution of infection.

Early HHV-6 replication is associated with morbidity non-related to CMV infection after kidney transplantation. Braz J Infect Dis 2012; 16:146-52.

Abstract
UNLABELLED Human herpesvirus type 6-(HHV-6) has been associated with morbidity after liver transplantation. OBJECTIVE The aim of this study was to determine the HHV-6 seroprevalence among donor-recipient pairs, analyze the incidence of early active infection, its clinical manifestation, interaction with CMV, and the related morbidity in the first year after kidney transplantation. METHODS 46 donor-recipient pairs had IgG evaluated by ELISA before transplantation: HHV-6(Pambio - USA) and CMV-(Roche - USA). A frozen whole blood sample collected weekly (from the 1st to the 6th week) was retrospectively tested for HHV-6 viral load (VL) determination by real time quantitative PCR (qPCR, Nanogen - Italy). Patients were preemptively surveyed for CMV by pp65 antigenemia (Ag, APAAP, immunohistochemistry, Biotest - Germany) from the 4th to the 12th week after transplantation. Active infection was defined as qPCR-HHV6+ (viral-load/mL-VL) and Ag+ (+cells/100.000 granulocytes), for HHV-6 and CMV, respectively. DCMV was defined as simultaneous positive antigenemia and suggestive signs/symptoms. Concerning +qPCR-HHV6, associated factors, clinical manifestation, interaction with CMV and morbidity were searched. RESULTS Pre-transplant HHV-6 seroprevalence was significantly higher among kidney recipients compared to their donors (82.6x54.8%; p = 0.005 [3.9 (1.4-10.4)]). Active infection by this virus occurred in 26.1% (12/46), with no association with previous IgG (p = 0.412). Median VL was 125 copies/mL (53-11.264), and the median Ag was 21 +cells (2-740). There was no association between HHV-6 and CMV activation after transplantation (p = 0.441), neither concerning DCMV (p = 0.596). Median highest Ag+ and days of ganciclovir treatment were similar between qPCR-HHV6 + or - (p = 0.206 and p = 0.124, respectively). qPCR-HHV6+ was associated with higher incidence of bacterial (p = 0.009) and fungal (p = 0.001) infections, and higher number (p = 0.001) of hospital admission and longer duration of hospitalization over the first 6 and 12 months post-transplantation (p = 0.033 and p = 0.001). CONCLUSION Latent HHV-6 infection is more common among recipients than donors before transplantation. Early active infection by this pathogen after transplantation does not increase DCMV incidence or severity during the first 3 months of follow-up. However, early HHV-6 replication is associated with other infections and hospitalizations in the first year.

Abstract
Cytomegalovirus (CMV) infection imposes a significant economic burden on susceptible patients after renal transplantation. Our study was conducted to determine the prediction, probability, consequences, and treatment costs of CMV infection under Canadian consensus guidelines in 270 sequential transplant patients. Transplant patients from donors positive (D(+)) for CMV into recipients negative (R(-)) for CMV received antiviral prophylaxis for 14 weeks and all but donor negative (D(-))/R(-) patients were monitored weekly for the CMVpp65 marker expression. Marker-positive patients and patients with CMV infection or disease received antiviral treatment. Within the first 6 months, 27% of the 270 patients tested had incidences of asymptomatic CMV infection, while 9% had CMV syndrome or disease. Only 1% of patients had infection after 6 months. The CMVpp65 marker levels were significantly greater in patients with syndrome or disease; but post-test probabilities and predictive value of the marker assay were low. Mean direct costs for care were $2256 and ranged from $927 for D(-)/R(-) patients to $7069 in the D(+)/R(-) patients. Extension of antiviral prophylaxis to D(+) or D(+)/R(+) patients significantly increased the estimated mean costs for an absolute reduction to 4% in CMV syndrome or disease. Our studies show that current guidelines for treatment enable effective control of CMV infection; however, alternative strategies have different economic impact.
