Insights
Polyarticular arthritis is the most common subtype of juvenile idiopathic arthritis in children. This subtype is more prevalent in girls, while pauciarticular arthritis is more common in boys.
Area of Science:
- Pediatric Rheumatology
- Immunology
- Clinical Epidemiology
Background:
- Juvenile idiopathic arthritis (JIA) is a heterogeneous group of autoimmune diseases affecting children.
- Understanding the frequency of JIA subtypes is crucial for diagnosis and treatment strategies.
- Previous studies on JIA subtype distribution in pediatric populations show regional variations.
Purpose of the Study:
- To determine the frequency of common subtypes of juvenile idiopathic arthritis (JIA) within a pediatric population.
- To analyze the distribution of JIA subtypes based on gender.
Main Methods:
- A cross-sectional study was conducted involving 95 children under 16 years of age diagnosed with arthritis.
- Data collection included physical examinations and detailed medical histories.
- Classification of arthritis subtypes was based on the number of affected joints: polyarticular (>5 joints) and pauciarticular (<4 joints).
Main Results:
- Polyarticular arthritis was the most frequent subtype, observed in 53.7% of cases.
- Pauciarticular arthritis was diagnosed in 46.3% of the study participants.
- A higher proportion of girls (67.3%) presented with polyarticular arthritis, whereas boys showed a higher prevalence of pauciarticular arthritis (62.8%).
Conclusions:
- Polyarticular arthritis is the predominant subtype of juvenile idiopathic arthritis in this pediatric cohort.
- Gender influences the distribution of JIA subtypes, with females more commonly affected by polyarticular and males by pauciarticular forms.
Objective:
To determine the frequency of common subtypes of juvenile idiopathic arthritis among paediatric population.
Methods:
The cross-sectional study was conducted at the National Institute of Child Health, Karachi, from January to June, 2010, and comprised children below 16 years of age with arthritis in one or more joints for at least 6 weeks. Physical examination was done and detailed history was recorded. When >5 joints of the body were involved, it was considered polyarthritis. If <4 joints were involved, it was pauciarticular arthritis.
Results:
Of the 95 cases in the study, 52(54.7%) were girls and 43(45.3%) were boys, with an overall mean age of 11±1.2 years. Polyarticular arthritis was found in 51(53.7%) subjects and pauciarticular arthritis in 44(46.3%). Out of 43 boys, 27(62.8%) had pauciarticular, while 35(67.3%) of the 52 girls had polyarticular arthritis.
Conclusions:
Polyarticular arthritis was the most common sub-type. Proportion of polyarticular arthritis was high in female children, while pauciarticular arthritis was high in male children.
