Ureaplasma parvum meningitis in neonates: A retrospective case study and literature review
Abstract
Objective: To investigate the clinical characteristics and advances in diagnosis and treatment of neonatal Ureaplasma parvum (U. parvum) meningitis.
Methodology: Clinical manifestations, diagnosis, treatment, and follow-up data of a neonate with persistent fever, normal blood routine, but persistently abnormal cerebrospinal fluid (CSF) results due to U. parvum meningitis were retrospectively analyzed. A literature review was conducted to identify relevant studies reporting on neonatal U. parvum meningitis published until May 2025.
Results: A male infant born at 35+2 weeks of gestation with eight hours of premature rupture of membranes (PROM) was admitted at 17 days of age with persistent fever. The routine blood test was normal, while the CSF suggested purulent meningitis. Empirical treatment was ineffective, and metagenomic next-generation sequencing (mNGS) of CSF confirmed U. parvum meningitis. The infant recovered after three weeks of azithromycin treatment, but a language delay was found at two-year follow-up. The literature review identified 16 previously reported cases of U. parvum meningitis, which were combined with the current case, totaling 17 cases. Main manifestations included fever and convulsions, or initial circulatory and respiratory symptoms. CSF in the included studies showed leukocytosis, decreased glucose, and elevated protein. Diagnosis was mainly based on mNGS, and the predominant treatment consisted of macrolides, sometimes combined with quinolones,…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
