Article Synopsis
- Human Rabies (HR) is a deadly disease caused by lyssaviruses, particularly the rabies virus (RABV).
- While dog transmissions have decreased in Latin America, there is an increase in rabies cases from wild animals.
- Effective treatment options are limited, making post-exposure prophylaxis and animal control critical for managing HR during the global pandemic.
The autoimmune lymphoproliferative syndrome (ALPS) is characterized by early-onset lymphadenopathy, splenomegaly, immune cytopenias, and an increased risk for B cell lymphomas. Most ALPS patients harbor mutations in the FAS gene, which regulates lymphocyte apoptosis. These are commonly missense mutations affecting the intracellular region of the protein and have a dominant-negative effect on the signaling pathway.

We recently described a syndrome of chronic nonmalignant lymphadenopathy, splenomegaly, and autoimmunity associated with a mutation in NRAS affecting hematopoietic cells, and initially we classified the disease as a variant of the autoimmune lymphoproliferative syndrome. Here, we demonstrate that somatic mutations in the related KRAS gene can also be associated with a nonmalignant syndrome of autoimmunity and breakdown of leukocyte homeostasis.

The research focused on different configurations, beliefs, representations, and forms of social organization of behavior thought to be associated with the population's capacity to efficiently follow AIDS prevention measures. Participants located in neighborhoods known for having large migrant populations were identified by Family Health Program Workers in Fortaleza and Teresina.

Methods: A sample of 502 adult AIDS patients out of 1,494 AIDS cases registered in a hospital in Fortaleza, Brazil, was investigated between 1986 and 1998. Sixteen cases were excluded due to death at the moment of the AIDS diagnosis and 486 were analyzed in the study.
