Summary
Yersinia arthritis typically resolves within a year, with most patients experiencing a benign long-term prognosis. Human leukocyte antigen B27 (HLA-B27) positivity was common, but severe outcomes like ankylosing spondylitis were rare.
Area of Science:
- Rheumatology
- Infectious Diseases
- Immunology
Background:
- Yersinia arthritis is a reactive arthritis that can occur after infection with Yersinia bacteria.
- The long-term outcomes and prognostic factors for Yersinia arthritis require further elucidation.
Purpose of the Study:
- To analyze the clinical course, serological markers, and inflammatory parameters in patients with Yersinia arthritis.
- To determine the long-term prognosis and identify potential risk factors for severe disease.
Main Methods:
- A cohort of 22 patients with acute Yersinia arthritis was followed for a mean of 10.7 years.
- Clinical data, agglutinating antibody titers against Yersinia, and laboratory markers of inflammation were assessed.
- Radiological evaluation of sacroiliac joints and symphysis was performed.
Main Results:
- The acute phase of Yersinia arthritis lasted from 1 month to 1 year in most patients.
- Human leukocyte antigen B27 (HLA-B27) was positive in 73% of cases.
- One patient developed severe ankylosing spondylitis with bilateral sacroiliac joint synostosis; two others had radiological changes without clinical symptoms.
- Agglutinating antibodies and laboratory signs of inflammation were negative in all patients during the follow-up period.
Conclusions:
- Yersinia arthritis generally has a benign long-term prognosis.
- While HLA-B27 positivity is frequent, severe sequelae like ankylosing spondylitis are uncommon.
- Absence of persistent inflammation markers suggests a self-limiting process.

Acute Pharyngitis
Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:

Classification
Acute pharyngitis can be categorized based on its underlying cause:
Bacterial 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...
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...
Poliomyelitis
Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...
Rabies
Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...
Arboviral Encephalitis
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
