minocycline and Hematologic-Diseases

To evaluate the efficacy and safety of tigecycline in treating secondary infections of patients with hematological diseases.. A total of 85 cases of hematological patients with secondary infections were classified into empirical and targeted therapy groups. Empirical therapy group was composed of patients receiving tigecycline as an alternative due to ineffective anti-infection treatment for 3-5 days in the absence of microbiological evidence while those taking tigecycline based on microbiological evidence belonged to targeted therapy group. Dosage regimen of tigecycline: loading dose 100 mg, 50 mg every 12 hours as maintenance therapy for 2-4 weeks.. Among them, except for 11 cases of bloodstream infections and 2 cases of fever for unknown reasons, the most common site for infection was lower respiratory tract. Among 45 isolated bacterial strains, Stenotrophomonas maltophilia (40%) was the most commonly seen while extended spectrum beta-lactamases (ESBLS)+ multidrug resistant gram negative bacilli 15.6%. Among 5 bacterial strains, there were 3 methicillin-resistant Staphylococcus aureus+golden staphylococci strains and 2 excrement enterococci. The total effective rate of tigecycline was 72.9%. And the bacterial clearance rates of acinetobacter baumannii, ESBLS+ gram-negative bacillus and stenotrophomonas maltophilia were 85%, 70% and 55% respectively. The effect of tigecycline was equivalent for two groups. Pneumonia patients obtained an effective rate of 71%, compared to those with bloodstream infections (54.5%). For patients whose absolute neutrophil counts were less than 0.2 × 10⁹/L, the effective rate decreased obviously (45% vs 81.5%, P = 0.003). Adverse reaction was mild due to mostly gastrointestinal symptoms.. Tigecycline is a new treatment choice in treating secondary multidrug resistant infections of patients with hematological diseases. Empirical therapy of tigecycline may improve the therapeutic efficacy of patients non-responding favorably to conventional anti-infectives.

A 17-year-old female patient who had been taking oral minocycline (50 mg twice daily) for 3 weeks for acne developed an eruption that progressed to an exfoliative dermatitis. This illness was also characterized by fever, lymphadenopathy, pharyngitis, a leukemoid reaction, lymphocytosis, eosinophilia, hepatitis, and noncardiogenic pulmonary edema. Dramatic improvement followed institution of corticosteroid therapy. Studies for infectious and collagen vascular diseases were negative. This severe illness was likely caused by minocycline, and we speculate that minocycline may have acted as a superantigen, causing lymphocyte over-activation and massive cytokine release.

We evaluated clinical effects and toxicities of a combination in treatment with cefodizime (CDZM) and minocycline (MINO) for infections complicated with hematological disorders in 67 patients. Fifty-nine patients were evaluable, including 32 with acute leukemia, 15 with malignant lymphoma, and 12 with other hematological disorders. Clinical efficacies were excellent in 17 cases, good in 24 cases, fair in 2 cases, and poor in 16 cases. The efficacy rate was 69.5% (41 cases/59 cases). This treatment was also effective in 8 of 12 cases in which granulocyte counts were less than 500/microliter through the course of administration. No subjective side effects were observed. Abnormal values in laboratory tests were noted in 5 cases. Mild elevations of GOT, GPT, Al-P and bilirubin were observed, but none was serious. Thus, the combination of CDZM and MINO is an effective and safe regimen for the treatment of infections in patients complicated with hematological disorders.
