Clarithromycin for community-acquired pneumonia in adults : focus on anti-inflammatory properties
AIM: To evaluate clinical efficacy, anti-inflammatory and immunomodulatory activity of clarithromycin in adults with severe community-acquired pneumonia (sCAP).
MATERIALS AND METHODS: A prospective observational study recruited adult hospitalized patients with verified sCAP. Clarithromycin was prescribed as a component of combination antibiotic therapy (ABT) with a β-lactam antibiotic (AB). The choice of β-lactam AB was carried out by the attending physician in accordance with national clinical guidelines and routine practice of the medical institution. Along with assessment clinical efficacy, the dynamics of inflammatory markers in blood serum was recorded: C-reactive protein, procalcitonin (PCT), tumor necrosis factor α, interleukins 1-beta (IL-1) and interleukin 6 (IL-6). The total duration of ABT was 7-14 days.
RESULTS: Altogether 20 patients (13 males, 7 females) aged from 18 to 84 years old were enrolled. As a result of the use of combined ABT with β-lactam AB and clarithromycin, a significant decrease in the level of C-reactive protein was noted by the 3-5th day of therapy (from 74.6 to 14.1 mg/l). An increase in serum PCT was observed in half of the patients; during treatment, the level of PCT significantly decreased. Similar dynamics was detected for IL-6 - its content in the blood serum decreased by the time of the end of ABT by 6.8 times compared with the baseline. A decrease in the level of tumor necrosis factor α to the reference value was observed in most patients already in the early stages - by 3-5 days of ABT. The majority of patients showed positive dynamics of clinical signs and symptoms with resolution of respiratory failure and other complications of sCAP. In almost half of the patients, the criteria for clinical stability were achieved in the early stages, which made it possible to switch to oral ABT.
CONCLUSION: The results of the study are consistent with literature data indicating a rapid decrease in inflammatory markers when clarithromycin is administered to patients with sCAP. Its results can be a starting point for comparative randomized trials assessing both clinical outcomes and immunological parameters when using different classes of antibiotics for the treatment of sCAP.
