Elevated Interleukin 1β and Interleukin 6 Levels in the Serum of Children With Hyperuricemia
Insights
Interleukin 1β (IL-1β) and IL-6 are elevated in children with hyperuricemia (HUA), indicating their potential role in the condition. These inflammatory markers may be linked to disease activity and clinical outcomes in pediatric HUA.
Area of Science:
- Pediatric Rheumatology
- Immunology
- Biochemistry
Background:
- Hyperuricemia (HUA) in children is associated with various health risks.
- The role of specific inflammatory markers like interleukin 1β (IL-1β) and IL-6 in pediatric HUA is not fully understood.
- Understanding these markers could offer insights into HUA pathogenesis and clinical management.
Purpose of the Study:
- To investigate serum levels of IL-1β and IL-6 in children diagnosed with HUA.
- To explore the clinical significance and potential correlations of IL-1β and IL-6 with disease characteristics in pediatric HUA.
Main Methods:
- A cohort of 71 children with HUA and 71 healthy controls were analyzed.
- Children with HUA were stratified based on the presence of acute gout-like attacks (Group I: with attacks, Group II: without attacks).
- Serum IL-1β and IL-6 levels were quantified using enzyme-linked immunosorbent assay (ELISA).
Main Results:
- Elevated serum levels of IL-1β and IL-6 were observed in children with HUA compared to controls.
- Significantly higher IL-1β and IL-6 levels were found in acute (IA) and remission (IB) phases of gout attacks, and in children without attacks (II) versus controls.
- IL-1β and IL-6 positively correlated with markers of inflammation (WBC, neutrophils, ESR, CRP) and kidney function (BUN, creatinine) in HUA patients.
Conclusions:
- Increased serum IL-1β and IL-6 levels are present in children with HUA, irrespective of acute gout history.
- These cytokines may reflect underlying inflammation and disease activity in pediatric HUA.
- Further research is warranted to determine the long-term prognostic significance of IL-1β and IL-6 in this population.
Purposes:
The aim of this study was to investigate the serum levels and clinical significance of interleukin 1β (IL-1β) and IL-6 in children with hyperuricemia (HUA).
Methods:
We included 71 children with HUA and 71 children with no HUA as control subjects. Children with HUA were divided into groups I and II according to whether they had a history of acute gout-like attacks (including sudden monoarthritis of rapid onset with intense pain and swelling). Group I was examined twice (A, in the acute phase; B, in the remission phase). Serum IL-1β and IL-6 levels were measured by enzyme-linked immunosorbent assay.
Results:
Serum IL-1β and IL-6 levels were increased in children with HUA and were overall statistically different from the control group (P < 0.05, respectively). Serum IL-1β and IL-6 were significantly higher in group IA in comparison with group IB, group II, and control subjects (P < 0.05, respectively), as well as in groups IB and II compared with control subjects (P < 0.05, respectively). In group IB, the serum IL-1β and IL-6 concentrations were higher than those in group II, but there were no statistical differences (P > 0.05). In addition, in children with HUA, serum IL-1β and IL-6 levels were positively associated with white blood cell count, neutrophil count, monocyte count, uric acid levels, erythrocyte sedimentation rate, C-reactive protein, blood urea nitrogen, and serum creatinine levels (all P < 0.05), but were not associated with triglycerides, total cholesterol, low-density lipoprotein cholesterol, or high-density lipoprotein cholesterol levels (all P > 0.05).
Conclusion:
IL-1β and IL-6 levels are increased in children with hyperuricemia, even if they have not had acute gout. Further studies are necessary to fully characterize the significance of IL-1β and IL-6 found in HUA children, and whether they could be correlated with long-term prognosis.
