Insights

Recurrent fevers, often inflammatory, can now be identified immunogenetically. This advances understanding and enables targeted therapies for these complex inflammatory conditions.

Area of Science:

  • Rheumatology
  • Immunology
  • Internal Medicine

Context:

  • Recurrent fevers present with cyclical febrile episodes and intervals of well-being.
  • Infections are the primary differential diagnosis for recurrent fever.
  • Many recurrent fevers are linked to inflammatory diseases with unknown causes.

Purpose:

  • To explore recent advancements in the immunogenetic identification of recurrent fevers.
  • To enhance the understanding of the physiopathogeny of inflammatory recurrent fevers.
  • To discuss the implications for developing specific therapeutic strategies.

Summary:

  • Recurrent fevers are defined by recurring episodes of fever followed by afebrile periods.
  • While infections are common causes, several recurrent fevers are inflammatory in nature.
  • Recent immunogenetic discoveries are crucial for diagnosing and treating these conditions.
  • These advances improve comprehension of disease mechanisms and facilitate targeted treatments.

Impact:

  • Enables precise immunogenetic diagnosis for previously unclear inflammatory fevers.
  • Facilitates a deeper understanding of the underlying mechanisms of recurrent inflammatory diseases.
  • Paves the way for the development of specific and effective therapeutic interventions.

Malaria01:29

Malaria

Malaria pathogenesis in humans reflects a delicate interplay between parasite biology and host response. Clinical illness reflects a host’s immune response to the parasite’s asexual replication cycle, which is often asymptomatic in individuals with partial immunity. From the parasite's perspective, transmission between mosquito and human with minimal host pathology is evolutionarily advantageous. Among the six Plasmodium species infecting humans, P. falciparum and P. vivax dominate in global...
Increased Body Temperature01:25

Increased Body Temperature

A body temperature above  38°C  (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in response to an infection or illness.
Streptococcal Pharyngitis01:27

Streptococcal Pharyngitis

Streptococcal pharyngitis, commonly known as “strep throat,” is an acute infection of the oropharyngeal tissues caused by the Gram‑positive Group A Streptococcus (Streptococcus pyogenes). Transmission occurs primarily through respiratory droplets expelled during coughing, sneezing, or talking.Mechanisms of Host Entry and Immune EvasionUpon entering the host, S. pyogenes adheres to the mucosal epithelial cells of the pharynx via surface proteins, notably lipoteichoic acid and the antiphagocytic...
Stages of Infection01:26

Stages of Infection

Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...
Encephalitis l: Introduction01:19

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...
