The Epidemiology, Management and Therapeutic Outcomes of Subdural Empyema in Neonates with Acute Bacterial Meningitis. Antibiotics (Basel) 2024; 13:377. [PMID: 38667053 PMCID: PMC11047628 DOI: 10.3390/antibiotics13040377] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2024] [Revised: 04/18/2024] [Accepted: 04/19/2024] [Indexed: 04/29/2024] Open
Abstract
Background: Subdural empyema is one of the more serious complications of bacterial meningitis and therapeutic challenges to clinicians. We aimed to evaluate the clinical characteristics, treatment, and outcome of subdural empyema in neonates with bacterial meningitis. Methods: A retrospective cohort study was conducted in two medical centers in Taiwan that enrolled all cases of neonates with subdural empyema after bacterial meningitis between 2003 and 2020. Results: Subdural empyema was diagnosed in 27 of 153 (17.6%) neonates with acute bacterial meningitis compared with cases of meningitis without subdural empyema. The demographics and pathogen distributions were comparable between the study group and the controls, but neonates with subdural empyema were significantly more likely to have clinical manifestations of fever (85.2%) and seizure (81.5%) (both p values < 0.05). The cerebrospinal fluid results of neonates with subdural empyema showed significantly higher white blood cell counts, lower glucose levels and higher protein levels (p = 0.011, 0.003 and 0.006, respectively). Neonates with subdural empyema had a significantly higher rate of neurological complications, especially subdural effusions and periventricular leukomalacia. Although the final mortality rate was not increased in neonates with subdural empyema when compared with the controls, they were often treated much longer and had a high rate of long-term neurological sequelae. Conclusions: Subdural empyema is not uncommon in neonates with acute bacterial meningitis and was associated with a high risk of neurological complications, although it does not significantly increase the final mortality rate. Close monitoring of the occurrence of subdural empyema is required, and appropriate long-term antibiotic treatment after surgical intervention may lead to optimized outcomes.

Diagnosis of Ureaplasma parvum meningitis by mNGS in an extremely low birth weight infant with multi-system lesions. Indian J Med Microbiol 2022; 40:455-458. [PMID: 35624028 DOI: 10.1016/j.ijmmb.2022.05.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2021] [Revised: 05/04/2022] [Accepted: 05/08/2022] [Indexed: 11/23/2022]
Abstract
Ureaplasma parvum encephalitis is a rare disease with high mortality in the neonates. While the manifestations are atypical and identification of U. parvum is difficult, diagnosis would always be delayed. Metagenomic next-generation sequencing (mNGS) is a pre-hypothesis free technique which could theoretically detect all the microbes in a sample. Herein we report a case of U. parvum meningitis identified by mNGS in an extremely low birth weight neonate complicated with multi-system lesions. The patient was treated with erythromycin and ciprofloxacin, symptoms were relieved in the following days and the patient was transferred to treat complications after three weeks' therapy.

Abstract
BACKGROUND Neonatal meningitis is a severe infectious disease of the central nervous system with high morbidity and mortality. Ureaplasma parvum is extremely rare in neonatal central nervous system infection. CASE PRESENTATION We herein report a case of U. parvum meningitis in a full-term neonate who presented with fever and seizure complicated with subdural hematoma. After hematoma evacuation, the seizure disappeared, though the fever remained. Cerebrospinal fluid (CSF) analysis showed inflammation with CSF pleocytosis (1135-1319 leukocytes/μl, mainly lymphocytes), elevated CSF protein levels (1.36-2.259 g/l) and decreased CSF glucose (0.45-1.21 mmol/l). However, no bacterial or viral pathogens in either CSF or blood were detected by routine culture or serology. Additionally, PCR for enteroviruses and herpes simplex virus was negative. Furthermore, the CSF findings did not improve with empirical antibiotics, and the baby experienced repeated fever. Thus, we performed metagenomic next-generation sequencing (mNGS) to identify the etiology of the infection. U. parvum was identified by mNGS in CSF samples and confirmed by culture incubation on mycoplasma identification medium. The patient's condition improved after treatment with erythromycin for approximately 5 weeks. CONCLUSIONS Considering the difficulty of etiological diagnosis in neonatal U. parvum meningitis, mNGS might offer a new strategy for diagnosing neurological infections.

Abstract
Mycoplasma species (spp.) can be commensals or opportunistic pathogens of the urogenital tract, and they can be commonly isolated from amniotic fluid, placenta, and fetal/neonatal tissue or blood in mothers delivering prematurely or their preterm infants. Although the presence of Mycoplasma spp. has been associated with adverse maternal-fetal outcomes such as preterm birth and maternal chorioamnionitis, it is less clear whether vertical transmission to the neonate results in colonization or active infection/inflammation. Moreover, the presence of Mycoplasma spp. in neonatal blood, cerebrospinal fluid, or tissue has been variably associated with increased risk of neonatal comorbidities, especially bronchopulmonary dysplasia (BPD). Although the treatment of the mother or neonate with antibiotics is effective in eradicating ureaplasma, it is not clear that the treatment is effective in reducing the incidence of major morbidities of the preterm neonate (eg, BPD). In this article, we review the animal and clinical data for ureaplasma-related complications and treatment strategies. [Pediatr Ann. 2020;49(7):e305-e312.].

Abstract
Ureaplasma species (spp.) are commonly regarded as low-virulence colonizers of the genitourinary tract. Intrauterine Ureaplasma infection, however, has been associated with chorioamnionitis and preterm birth. The overall impact of a neonatal Ureaplasma colonization is yet to be understood. High pathogen prevalence and frequent neurological morbidities particularly in immature preterm infants call for an assessment of the significance of Ureaplasma spp. in neonatal neuroinflammation. This narrative review summarizes clinical data, animal studies, and in vitro results to elucidate potential Ureaplasma-associated neurological morbidities as well as underlying mechanisms. Increasing evidence indicates an involvement of Ureaplasma spp. in invasive central nervous system infections, suggesting a meticulous ability of Ureaplasma spp. to interfere with immune defense mechanisms. Ultimately, Ureaplasma spp. should be considered as relevant pathogens in neonatal neuroinflammation.
