[Three cases of idiopathic thrombocytopenic purpura showing an increase in the platelet count following clarithromycin treatment].
ABSTRACT Macrolides have immuno-modulatory effects as well as anti-bacterial effects. We successfully treated three idiopathic thrombocytopenic purpura (ITP) patients with clarithromycin (CAM). Case 1: A 69-year-old male ITP patient was treated with CAM at a dose of 400 mg/day. His platelet count increased from 5.6 x 10(4)/microliter to 10.1 x 10(4)/microliter. Case 2: A 72-year-old male ITP patient was treated with CAM at the same dose. The platelet count increased from 1.3 x 10(4)/microliter to 12.3 x 10(4)/microliter. Case 3: A 68-year-old female ITP patient was treated with CAM at the same dose. The platelet count increased from 2.3 x 10(4)/microliter to 13 x 10(4)/microliter. These facts suggest that CAM is useful in the treatment of ITP.

ABSTRACT: Macrolides have both immunomodulatory and antibacterial effects. We report 3 cases of primary immune thrombocytopenia (ITP) patients who were successfully treated with macrolides, irrespective of Helicobacter pylori (H. pylori) infection status. Case 1, an 88-year-old woman who was an H. pylori-positive ITP patient, was treated with clarithromycin (CAM). CAM was effective temporarily. As an alternative to CAM, she was successfully treated with erythromycin (EM) for more than 7 months. Case 2, a 61-year-old man who was an H. pylori-negative ITP patient, was unsuccessfully treated with CAM but successfully treated with EM. Case 3, a 75-year-old woman who was a H. pylori-negative ITP patient, was treated with CAM. CAM was effective temporarily. After approximately 6 months, she was treated with EM for a common cold, and her platelet count increased rapidly. Based on these findings, macrolide treatment was effective for ITP. The effectiveness of macrolides might suggest immunomodulatory effects as well as antibacterial effects for H. pylori.The Korean journal of hematology 06/2011; 46(2):139-42.

ABSTRACT: Long-term therapy with the macrolide antibiotic erythromycin was shown to alter the clinical course of diffuse panbronchiolitis in the late 1980s. Since that time, macrolides have been found to have a large number of anti-inflammatory properties in addition to being antimicrobials. These observations provided the rationale for many studies performed to assess the usefulness of macrolides in other inflammatory diseases including skin and hair disorders, such as rosacea, psoriasis, pityriasis rosea, alopecia areata, bullous pemphigoid, and pityriasis lichenoides. This paper summarizes a collection of clinical studies and case reports dealing with the potential benefits of macrolides antibiotics in the treatment of selected dermatoses which have primarily been classified as noninfectious and demonstrating their potential for being disease-modifying agents.Mediators of Inflammation 01/2012; 2012:159354. · 3.88 Impact Factor
