ABSTRACT

Ramsay Hunt syndrome (RHS) is a manifestation of reactivated varicella-zoster virus (VZV) from the geniculate ganglion. Data on clinical features and outcomes of patients with RHS and concurrent VZV meningitis (henceforth RHS meningitis) are limited. Thus, we conducted a nationwide population-based cohort study of all adults hospitalized for RHS meningitis at the departments of infectious diseases in Denmark from 2015 to 2020. Patients with VZV meningitis without cranial nerve palsies were included for comparison. In total, 37 patients with RHS meningitis (mean annual incidence: 1.6/1 000 000 adults) and 162 with VZV meningitis without cranial nerve palsies were included. In RHS meningitis, the median age was 52 years (interquartile range: 35-64), and in addition to peripheral facial nerve palsy (100%), dizziness (46%), and hearing loss (35%) were common symptoms. The triad of headache, neck stiffness, and photophobia/hyperacusis was less common in RHS meningitis than in VZV meningitis without cranial nerve palsies (0/27 [0%] vs. 24/143 [17%]; p = 0.02). At 30 days after discharge, 18/36 (50%) patients with RHS meningitis had persistent peripheral facial nerve palsy, with no statistically significant difference between those treated with and without adjuvant glucocorticoids (6/16 [38%] vs. 12/20 [60%]; p = 0.18). Additional sequelae of RHS meningitis included dizziness (29%), neuralgia (14%), tinnitus/hyperacusis (11%), hearing loss (9%), headache (9%), fatigue (6%), and concentration difficulties (3%). In conclusion, clinical features and outcomes of RHS meningitis were primarily related to cranial neuropathies.

ABSTRACT

From November to December 2012 in Sélingué-Mali, blood samples from 88 febrile patients who tested negative by malaria Paracheck® rapid diagnostic tests (RDTs) were used to assess the presence of sub-RDT Plasmodium falciparum as well as Borrelia, Coxiella burnetii, and Babesia applying molecular tools. Plasmodium sp. was present among 57 (60.2%) of the 88 malaria RDT-negative patients, whereas the prevalence of Borrelia, C. burnetii, and Babesia were 3.4% (N = 3), 1.1% (N = 1), and 0.0%, respectively. The additional diagnostic use of polymerase chain reaction (PCR) identified a high proportion of Plasmodium sp.-positive samples and although this may be a concern for malaria control, the respective PCR-identified malaria infections were less likely responsible for the observed fevers given the low parasite density. Also, the low infection levels of Borrelia and C. burnetii and lack of Babesia among the febrile patients call for further studies to assess the causes of fever among malaria RDT-negative patients in Sélingué.
