Serum immunoreactive trypsin in cystic fibrosis

Area of Science:

• Biochemistry
• Pediatrics
• Genetics

Background:

• Cystic Fibrosis (CF) is a genetic disorder affecting multiple organs.
• Early diagnosis of CF is crucial for timely intervention and improved outcomes.
• Immuno-reactive trypsin (IR-TRY) is a potential biomarker for CF.

Purpose of the Study:

• To measure immuno-reactive trypsin (IR-TRY) levels in a cohort of cystic fibrosis (CF) patients.
• To investigate the correlation between IR-TRY levels, patient age, and pancreatic functional status.
• To evaluate the utility of IR-TRY measurements for neonatal screening of CF.

Main Methods:

• Radioimmunoassay (RIA) was employed to quantify IR-TRY levels.
• The study included 185 patients diagnosed with CF, ranging in age from 4 days to 34 years.
• Statistical analysis was performed to assess correlations.

Main Results:

• IR-TRY levels were successfully measured in all 185 CF patients.
• Significant correlations were observed between IR-TRY values and patient age.
• IR-TRY levels also showed a correlation with the functional state of the pancreas.

Conclusions:

• IR-TRY measurement is a feasible method for assessing trypsin levels in CF patients.
• The observed correlations suggest IR-TRY can provide insights into pancreatic function in CF.
• These findings support the potential application of IR-TRY in neonatal screening protocols for cystic fibrosis.
