Introduction:
Parotiditis is a viral infection that produces a non-suppurative inflammation of the parotid glands, although it may affect other salivary glands, the testicles, meninges and the pancreas. Clinical meningitis appears in 1-10% of cases, normally between the 4th and the 10th day after infection of the parotid glands. In this study, we analyse the clinical and analytic characteristics of the patients admitted to our Neurology Department over the last 12 years.
Case Reports:
A retrospective study was conducted by analysing the hospital discharge reports. The eligibility criterion was the existence of an acute meningeal syndrome linked to the presence of positive IgM titres for the parotiditis virus. In all, 13 cases were found, with a mean age of 16.5 years, and most of them were males (92.3%). Parotiditis preceded meningitis in all our patients with an average of 8.3 days, while orchiepididymitis, when it occurred, appeared at the same time or after meningitis. Analysis of the cerebrospinal fluid showed a lymphocyte profile with glycorrhachia above 40%, except in two cases that showed a non-persistent neutrophilic profile. There was a transient 30.7% reduction in prothrombin time in the patients. No sequelae were observed.
Conclusions:
Vaccination campaigns have drastically reduced the number of cases of meningitis due to this germ since the second half of the 90s. This virus must be borne in mind in cases of meningitis in young males who come from underdeveloped countries.
Insights
Meningitis linked to parotiditis virus infection is rare but serious, primarily affecting young males. Prompt diagnosis and awareness are crucial, especially in underdeveloped regions, as vaccination has significantly reduced cases.
Area of Science:
- Virology
- Neurology
- Infectious Diseases
Background:
- Parotiditis is a viral infection causing inflammation of salivary glands, potentially affecting other organs like testicles, meninges, and pancreas.
- Clinical meningitis occurs in 1-10% of parotiditis cases, typically 4-10 days post-infection.
Purpose of the Study:
- To analyze the clinical and analytical characteristics of patients with parotiditis-associated meningitis.
- To understand the presentation and outcomes of this rare complication.
Main Methods:
- Retrospective analysis of hospital discharge reports over 12 years.
- Inclusion criteria: acute meningeal syndrome with positive IgM titres for the parotiditis virus.
- 13 eligible cases identified.
Main Results:
- Mean age of patients was 16.5 years; 92.3% were male.
- Parotiditis preceded meningitis by an average of 8.3 days.
- Cerebrospinal fluid analysis revealed a lymphocyte profile with normal glucose levels; no sequelae observed.
Conclusions:
- Vaccination campaigns have significantly decreased parotiditis-related meningitis cases since the late 1990s.
- The parotiditis virus should be considered in meningitis cases among young males, particularly from underdeveloped countries.
