Evaluation of usefulness of hs-CRP and ferritin assays in patients with nasal polyps.

BACKGROUND: Chronic nature of the nasal polyps, tendency to recurrence, and lack of satisfying treatment need the diagnostic's parameters which show early inflammatory state as ferritin and hs-CRP. The Aim of Study. Assessment of hs-CRP and ferritin blood levels in nasal polyps patients in evaluation of treatment efficacy. METHODS: All 38 patients were divided into 2 groups. Group I included 19 patients with anti-inflammatory therapy 2 weeks after surgery. Group II included 19 patients without anti-inflammatory therapy 2 weeks after surgery. The levels of hs-CRP and ferritin have been assessed before and 2 and 6 weeks after surgical treatment. RESULTS: Research showed statistically significant difference of ferritin's concentration between examined groups 6 weeks after surgery (P < 0.05) and statistically significant difference of hs-CRP concentration 2 and 6 weeks after surgery (P < 0.05). CONCLUSION: (1) The analysis of serum ferritin and hs-CRP concentrations can be useful in early postoperative detection of inflammatory state in patients with nasal polyps and for the effectiveness of therapy. (2) Lack of correlation between mean ferritin and hs-CRP serum levels, at each diagnostic and monitoring stage, shows that they are independent and cannot be determined interchangeably.

BACKGROUND: Chronic rhinosinusitis with nasal polyps is social, clinical and cost-effective problem, by reason of bothersome symptoms, chronic nature of the disease, tendency to recur and lack of satisfying treatment. AIM: The aim of this study is assessment of suitability of hsCRP, ferritin and blood levels in nasal polyps patients in evaluation of treatment efficacy. METHODS: The study enrolled 38 patients between 20 and 68 years of age. Patients were divided into 2 groups. Levels of ultrasensitive CRP ferritin and TPS have been measured in all patients. The ultrasensitive CRP levels have been measured by chemiluminescence method. Ferritin levels have been measured by MEIA method. The TPS levels have been measured by chemiluminescence method. RESULTS: Comparison of mean ferritin levels in both study groups in each stage of observation shows the significant difference of mean values in only 6 weeks after surgery. Mean ferritin level is significantly lower in group I than in group II (p<0.05). Mean hsCRP levels vary from one corresponding to ferritin levels. Statistically significant difference between study groups in 2nd and 6th week after surgery has been ascertained (p<0.05). Similarly, like in ferritin levels, the TPS levels are significantly different in 6th week after surgery. CONCLUSIONS: Analysis of ferritin, hsCRP and TPS serum levels indicates that these may be useful in assessment of treatment efficacy in patients with nasal polyps. Rise of the chosen inflammatory state parameter level in the postoperative monitoring and anti-inflammatory treatment introduction in nasal polyps patients may inhibit the recurrence of the disease.
