Summary
Infectious meningitis can cause pituitary deficiencies, appearing acutely or developing later. Pituitary function should be monitored in patients post-meningitis.
Area of Science:
- Endocrinology
- Neurology
- Infectious Diseases
Background:
- Previous studies suggest central nervous system infections may lead to pituitary deficiency.
- Pituitary dysfunction is a potential complication of infectious diseases affecting the brain.
Purpose of the Study:
- To prospectively evaluate pituitary function in patients with infectious meningitis.
- Assess pituitary function during the acute phase and at 12 months post-infection.
Main Methods:
- Studied 16 patients admitted with infectious meningitis.
- Assessed basal pituitary function within 24 hours of admission.
- Performed basal and stimulated (insulin tolerance test) testing at 12 months in 12 patients.
Main Results:
- In the acute phase, 31.25% showed hormone deficiencies (gonadotropic, somatotropic).
- At 12 months, 31.25% had anterior pituitary hormone deficiencies (corticotropic, somatotropic); 4 patients developed new deficiencies.
- Low T(3) syndrome was observed in 44% during the acute phase, resolving by 12 months.
Conclusions:
- A significant proportion of patients develop pituitary deficiencies after acute infectious meningitis.
- These deficiencies can be isolated or combined, presenting acutely or later.
- Monitoring pituitary function is crucial for patients recovering from infectious meningitis.

01:18Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
01:22Bacterial Meningitis I: Introduction
Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
01:26Bacterial Meningitis II: Pathophysiology
Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...
01:27Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
01:26Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
01:24Bacterial Meningitis
Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
