Detection of periodontal disease activity based on histatin degradation in individuals with cerebral palsy
OBJECTIVES: This proof-of-concept study aimed at evaluating the proteolytic profile of histatin 1 and 5 in saliva of adolescents with spastic cerebral palsy (CP) with gingivitis. METHODS: This cross-sectional study included 24 individuals allocated into three groups: G1 (CP with gingivitis; n = 8),...

Sumario: | OBJECTIVES: This proof-of-concept study aimed at evaluating the proteolytic profile of histatin 1 and 5 in saliva of adolescents with spastic cerebral palsy (CP) with gingivitis. METHODS: This cross-sectional study included 24 individuals allocated into three groups: G1 (CP with gingivitis; n = 8), G2 (without CP and without gingivitis; n = 8), and G3 (without CP and with gingivitis; n = 8). The gingival index (GI) and simplified oral hygiene index (OHI–S) were evaluated. Whole saliva was collected and used to assess the rate and mode of histatin 1 and 5 at different times. The degradation products were visualized after cationic PAGE and the protein band densities (BDs) were compared with a protein standard. Fragmentation products were collected from the gel, pooled by group and characterized by mass spectrometry. BDs and gingival health parameters were analyzed by One-Way ANOVA or Kruskal Wallis tests, whereas poisson multilevel regression was used to the factors that influenced histatin degradation (α = 5%). RESULTS: Groups G1 and G3 differed significantly on OHI–S, visible biofilm, oral calculus and GI (p < 0.001). Poisson Regression showed that: 1) CP and gingivitis influenced the degradation of histatin 1 and 5 (p < 0.05); 2) The degradation of histatin 5 was influenced by age and male sex (p < 0.05); and 3) GI influenced significantly the degradation of histatin 1 (p < 0.001). Unique histatin degradation peptides were identified in individuals with gingivitis. CONSLUSIONS: These data demonstrated that both the kinetics and pattern of histatins degradation differ according to the gingival health or disease conditions. |
