Insights

Chronic strongyloidiasis can lead to recurrent meningitis, especially with human T-lymphotropic virus type 1 (HTLV-1) infection. Ivermectin may be more effective than thiabendazol for treating this rare but deadly complication.

Area of Science:

  • Infectious Diseases
  • Neurology
  • Parasitology

Background:

  • Chronic strongyloidiasis is a parasitic infection that can lead to serious complications.
  • Meningitis secondary to strongyloidiasis is rare but has a high mortality rate.
  • Recurrent meningitis necessitates effective treatment of the underlying parasitic infection.

Purpose of the Study:

  • To report cases of recurrent meningitis associated with chronic strongyloidiasis and human T-lymphotropic virus type 1 (HTLV-1) infection.
  • To compare the efficacy of ivermectin and thiabendazol in treating strongyloidiasis-related meningitis.

Main Methods:

  • Case series reporting five patients with recurrent meningitis.
  • Review of clinical symptoms, causative organisms, and treatment outcomes.
  • Comparison of treatment responses to thiabendazol and ivermectin.

Main Results:

  • Five cases of recurrent meningitis linked to chronic strongyloidiasis and HTLV-1 infection were identified.
  • Common bacterial pathogens included Escherichia coli, Streptococcus bovis, and Klebsiella pneumonia.
  • Four patients experienced multiple recurrences despite thiabendazol treatment; ivermectin showed better eradication potential.

Conclusions:

  • Chronic strongyloidiasis, particularly in HTLV-1 infected individuals, poses a risk for recurrent meningitis.
  • Ivermectin appears to be a more effective treatment for eradicating strongyloidiasis than thiabendazol.
  • Prompt diagnosis and effective antiparasitic treatment are crucial for managing this severe complication.

Bacterial 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...

Bacterial Meningitis II: Pathophysiology01:26

Bacterial 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...

Viral Meningitis01:18

Viral 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...

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...

Brain 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...

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
