Outcomes of Herpes Simplex Virus Pneumonitis in Critically Ill Patients. Viruses 2022; 14:v14020205. [PMID: 35215799 PMCID: PMC8876614 DOI: 10.3390/v14020205] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2021] [Revised: 01/16/2022] [Accepted: 01/17/2022] [Indexed: 01/27/2023] Open
Abstract
Critically ill patients, such as those in intensive care units (ICUs), can develop herpes simplex virus (HSV) pneumonitis. Given the high prevalence of acute respiratory distress syndrome (ARDS) and multiple pre-existing conditions among ICU patients with HSV pneumonitis, factors predicting mortality in this patient population require further investigation. In this retrospective study, the bronchoalveolar lavage or sputum samples of ICU patients were cultured or subjected to a polymerase chain reaction for HSV detection. Univariable and multivariable Cox regressions were conducted for mortality outcomes. The length of hospital stay was plotted against mortality on Kaplan–Meier curves. Among the 119 patients with HSV pneumonitis (age: 65.8 ± 14.9 years), the mortality rate was 61.34% (73 deaths). The mortality rate was significantly lower among patients with diabetes mellitus (odds ratio [OR] 0.12, 95% confidence interval [CI]: 0.02–0.49, p = 0.0009) and significantly higher among patients with ARDS (OR: 4.18, 95% CI: 1.05–17.97, p < 0.0001) or high (≥30) Acute Physiology and Chronic Health Evaluation II scores (OR: 1.08, 95% CI: 1.00–1.18, p = 0.02). Not having diabetes mellitus (DM), developing ARDS, and having a high Acute Physiology and Chronic Health Evaluation II (APACHE II) score were independent predictors of mortality among ICU patients with HSV pneumonitis.

Herpes DNAemia and TTV Viraemia in Intensive Care Unit Critically Ill Patients: A Single-Centre Prospective Longitudinal Study. Front Immunol 2021; 12:698808. [PMID: 34795661 PMCID: PMC8593420 DOI: 10.3389/fimmu.2021.698808] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2021] [Accepted: 10/12/2021] [Indexed: 11/21/2022] Open
Abstract
Introduction We analysed blood DNAemia of TTV and four herpesviruses (CMV, EBV, HHV6, and HSV-1) in the REAnimation Low Immune Status Marker (REALISM) cohort of critically ill patients who had presented with either sepsis, burns, severe trauma, or major surgery. The aim was to identify common features related to virus and injury-associated pathologies and specific features linking one or several viruses to a particular pathological context. Methods Overall and individual viral DNAemia were measured over a month using quantitative PCR assays from the 377 patients in the REALISM cohort. These patients were characterised by clinical outcomes [severity scores, mortality, Intensive Care Unit (ICU)-acquired infection (IAI)] and 48 parameters defining their host response after injury (cell populations, immune functional assays, and biomarkers). Association between viraemic event and clinical outcomes or immune markers was assessed using χ2-test or exact Fisher’s test for qualitative variables and Wilcoxon test for continuous variables. Results The cumulative incidence of viral DNAemia increased from below 4% at ICU admission to 35% for each herpesvirus during the first month. EBV, HSV1, HHV6, and CMV were detected in 18%, 12%, 10%, and 9% of patients, respectively. The incidence of high TTV viraemia (>10,000 copies/ml) increased from 11% to 15% during the same period. Herpesvirus viraemia was associated with severity at admission; CMV and HHV6 viraemia correlated with mortality during the first week and over the month. The presence of individual herpesvirus during the first month was significantly associated (p < 0.001) with the occurrence of IAI, whilst herpesvirus DNAemia coupled with high TTV viraemia during the very first week was associated with IAI. Herpesvirus viraemia was associated with a lasting exacerbated host immune response, with concurrent profound immune suppression and hyper inflammation, and delayed return to immune homeostasis. The percentage of patients presenting with herpesvirus DNAemia was significantly higher in sepsis than in all other groups. Primary infection in the hospital and high IL10 levels might favour EBV and CMV reactivation. Conclusion In this cohort of ICU patients, phenotypic differences were observed between TTV and herpesviruses DNAemia. The higher prevalence of herpesvirus DNAemia in sepsis hints at further studies that may enable a better in vivo understanding of host determinants of herpesvirus viral reactivation. Furthermore, our data suggest that EBV and TTV may be useful as additional markers to predict clinical deterioration in ICU patients.

Abstract
Infectious diseases are one of the main causes of morbidity and mortality worldwide. With new pathogens continuously emerging, known infectious diseases reemerging, increasing microbial resistance to antimicrobial agents, global environmental change, ease of world travel, and an increasing immunosuppressed population, recognition of infectious diseases plays an ever-important role in surgical pathology. This becomes particularly significant in cases where infectious disease is not suspected clinically and the initial diagnostic workup fails to include samples for culture. As such, it is not uncommon that a lung biopsy becomes the only material available in the diagnostic process of an infectious disease. Once the infectious nature of the pathological process is established, careful search for the causative agent is advised. This can often be achieved by examination of the hematoxylin and eosin-stained sections alone as many organisms or their cytopathic effects are visible on routine staining. However, ancillary studies such as histochemical stains, immunohistochemistry, in situ hybridization, or molecular techniques may be needed to identify the organism in tissue sections or for further characterization, such as speciation.

Abstract
Viral lower respiratory tract infections (LRTIs) are an underappreciated cause of critical illness in adults. Recent advances in viral detection techniques over the past decade have demonstrated viral LRTIs are associated with rates of morbidity, mortality, and health care utilization comparable to those of seen with bacterial community acquired and nosocomial pneumonias. In this review, we describe the relationship between viral LRTIs and critical illness, as well as discuss relevant clinical features and management strategies for the more prevalent respiratory viral pathogens.

Abstract
BACKGROUND Acute bacterial meningitis (ABM) and herpes simplex type 1 (HSV-1) encephalitis are two rare but serious infections affecting the central nervous system (CNS). Concurrent bacterial and viral CNS infection has occasionally been reported. OBJECTIVES To illustrate the possibility of intrathecal infection with both Streptococcus pneumonia and HSV-1 by presenting a case and to examine whether herpesvirus reactivation is common in ABM. STUDY DESIGN We report a case diagnosed with HSV-1 reactivation in the cerebrospinal fluid (CSF) during treatment for pneumococcal ABM. A retrospective analysis of CSF samples from 21 patients with ABM was performed, with analysis of DNA from HSV-1 and four other neurotropic herpesviruses. RESULTS All 21CSF samples were negative for HSV-1, HSV-2, varicella zoster-virus, Epstein-Barr virus and human herpesvirus 6 DNA by PCR. CONCLUSIONS Although herpesvirus infection does not seem to be a common phenomenon in ABM we suggest that HSV-1 reactivation could be kept in mind if patients with ABM show symptoms or signs compatible with encephalitis.

Abstract
PURPOSE OF THE REVIEW Viruses are an increasingly recognized cause of community-acquired pneumonia (CAP), but their exact role in nosocomial pneumonia is still debated. This review focuses on the role of viruses as a cause of nosocomial pneumonia. RECENT FINDINGS Respiratory viruses may be responsible for healthcare-associated pneumonia, because affected patients and those with CAP have the same risk factors for viral disease. In mechanically ventilated patients, viruses belonging to the Herpesviridae family, namely herpes simplex virus (HSV) and cytomegalovirus, can be reactivated and cause bronchopneumonitis or ventilator-associated pneumonia, respectively. Recent results confirmed the high rate of HSV reactivation in the distal airways of mechanically ventilated patients, and that patients with high virus loads (>10(5) copies/ml of bronchoalveolar lavage fluid) have poorer outcomes than those with low or no virus load. However, the responsibility of mimivirus, initially described as a possible cause of pneumonia, was not confirmed for nosocomial pneumonia. SUMMARY Respiratory viruses are mainly responsible for CAP, but they may also cause healthcare-associated pneumonia. HSV bronchopneumonitis and cytomegalovirus pneumonia are not rare diseases, and patients with Herpesviridae lung infections have worse prognoses than those without. Whether or not those Herpesviridae infections are responsible for true morbidity or morbidity remains to be determined.

Abstract
Sepsis is the commonest cause of admission to medical ICUs across the world. Mortality from sepsis continues to be high. Besides shock and multi-organ dysfunction occurring following the intense inflammatory reaction to sepsis, complications arising from sepsis-related immunoparalysis contribute to the morbidity and mortality from sepsis. This review explores the basis for sepsis related immune dysfunction and discusses its clinical implications for the treating intensivist. Recent trends indicate that a significant proportion of septic patients succumb to the complications of secondary infections and chronic critical care illness from the initial bout of sepsis. Therefore care-givers in the ICU need to be aware of the impediments posed by sepsis-related immune dysfunction that can impair recovery in patients with sepsis and contribute to sepsis-related mortality.

J Clin Virol 2014; 60:215-21.

Abstract
BACKGROUND AND OBJECTIVE The relevance of the detection of herpes simplex virus type 1 (HSV-1) in the respiratory tract of patients in the intensive care unit (ICU) is unclear. Therefore, it is uncertain whether treatment with an antiviral agent could be beneficial for these patients. STUDY DESIGN We retrospectively reviewed the records of ICU patients with a positive HSV-1 culture in the respiratory tract or bronchoalveolar lavage (BAL) fluid. We evaluated whether acyclovir treatment (n=106) could have a beneficial effect on mortality as compared with the standard treatment (n=106). RESULTS Acyclovir treatment was positively linked to in-hospital and ICU-mortality reduction. This favourable influence remained present after correcting for possible confounders and using propensity-adjusted and propensity-matched cohorts: with an odds ratio in the treated group of 3.19 (95% CI 1.79-5.69, p=0.001) for ICU survival and of 3.55 (95% CI 2.16-5.85, p<0.001) for in-hospital survival. The subgroup with HSV-1 detected in the BAL-fluid is the sole contributor to this difference. In the BAL-fluid detected group, 48% (n=10) of non-treated patients died in the ICU, versus 21% (n=6) in the acyclovir-treated group (p=0.033), occurring despite an even longer duration of ventilation or ICU stay. CONCLUSIONS These data highlight the hypothesis that it might be worthwhile to consider treatment of HSV-1 in ICU patients depending on the type of respiratory sample in which the virus is detected. These results warrant a prospective trial to prove causality.
