Recent AIDS endemic causes the worldwide increase in intractable mycobacterial infections including extrapulmonary tuberculosis due to drug resistant organisms and disseminated Mycobacterium avium complex infections. Therefore, new antituberculous (antimycobacterial) drugs and development of regimens and protocols for clinical treatment of such mycobacterial infections are urgently needed. Here, I described the present situations of new antituberculous agents, in particular new rifamycin derivatives including rifabutin and benzoxazinorifamycin (KRM-1648), new macrolides such as clarithromycin and azithromycin, and new quinolones including sparfloxacin, ofloxacin, ciprofloxacin, fleroxacin, AM-1155 and so on. Their in vitro antimycobacterial activities, therapeutic efficacy against experimental infections induced in animals especially in mice, and clinical trials using these drugs are summarized by referring to recent studies by worldwide investigators including us. Moreover, this paper dealt with some of recent attempts for chemotherapy of mycobacterial infections employing the drug delivery system using liposomal microvesicles as a carrier of drugs. Although these new drugs and development in new regimens appreciably potentiated the efficacy of controlling mycobacterial infections, in particular M. avium complex infections, it remains very difficult to achieve a complete elimination of the organisms from the sites of infection, even if provided multi-drug regimens using new drugs having excellent antimycobacterial activity and sufficient dosages. Therefore, it seems important to make an effort to elucidate the mechanisms of induction of immuno-unresponsiveness in hosts in progressed state of mycobacterial infection, as well as to develop new drugs possessing more potent antimycobacterial activity.

Retrospective study of 17 patients (19 histological specimens) diagnosed with cutaneous NTM infections and confirmed by culture-based partial sequencing of the 16S rRNA gene at the American University of Beirut Medical Center between 2005 and 2008.

Twelve cases of PASI were caused by group A beta-hemolytic streptococci T type 28 with an identical PFGE profile: 6 of the cases were in children attending the same kindergarten, 4 were connected otherwise to the cluster and 2 cases seemed to be unrelated. Five cases of PASI with different T types and PFGE profiles were diagnosed during the same period giving an estimated annual incidence of 2 to 7 per 1000 children. Penicillin V was ineffective in 3 cases, and no recurrence was seen after change of the treatment to oral clarithromycin.
The in vitro susceptibilities of 192 consecutive clinical strains of Pasteurella spp. isolated between 1996 and 2003 from soft tissue pus (n = 146), respiratory tract specimens (n = 38) and blood (n = 8) were studied by an agar dilution method. All isolates were susceptible to minocycline, cefotaxime, ofloxacin, ciprofloxacin and levofloxacin. Most strains were susceptible to moxifloxacin, amoxicillin, azithromycin and clarithromycin, whereas lower susceptibility rates to telithromycin (89.4%) were observed among respiratory tract isolates.

There is evidence that macrolide antibiotics are effective in the treatment of chronic airway inflammatory diseases, probably through actions other than their antibacterial properties. In order to determine whether macrolides affect the nitric oxide-generating system in the respiratory tract, rat pulmonary alveolar macrophages (PAMs) were studied in vitro. The release of NO was assessed by direct measurement with a specific amperometric sensor for this molecule, and the expression of type II NO synthase (NOS) messenger ribonucleic acid (mRNA) was determined by Northern blotting. Incubation of PAMs with lipopolysaccharide from Escherichia coli and recombinant human interferon-gamma caused release of NO, which was accompanied by induction of type II NOS mRNA. The release of NO was reduced by coincubation of cells with the macrolides erythromycin, clarithromycin and josamycin in a concentration-dependent manner, the maximal inhibition being 73+/-10, 81+/-6 and 84+/-9%, respectively, but was not altered by amoxycillin or cefaclor. These macrolides likewise inhibited the induction of type II NOS mRNA, whereas no inhibitory effects were observed with amoxycillin or cefaclor. These results suggest that macrolide antibiotics specifically inhibit type II NO synthase gene expression and consequently reduce NO production by rat pulmonary alveolar macrophages, which might result in attenuation of airway inflammation.

One-week low-dose triple therapy consisting of omeprazole, clarithromycin and metronidazole is a highly effective and well-tolerated approach to the cure of H. pylori infection in patients with a duodenal ulcer. Our data suggest that continuation of antisecretory drug therapy beyond anti-H. pylori therapy is actually excessive regarding relief from dyspeptic symptoms and healing of duodenal ulcers.

Multidrug resistant leprosy, defined as resistance to rifampin, dapsone and fluoroquinolones (FQ), has been described in Mycobacterium leprae. However, the in vivo impact of fluoroquinolone resistance, mainly mediated by mutations in DNA gyrase (GyrA2GyrB2), has not been precisely assessed. Our objective was to measure the impact of a DNA gyrase mutation whose implication in fluoroquinolone resistance has been previously demonstrated through biochemical studies, on the in vivo activity of 3 fluoroquinolones: ofloxacin, moxifloxacin and garenoxacin.

The authors believe that clarithromycin and atovaquone may constitute valid alternatives for the treatment of cerebral toxoplasmosis. Nonetheless, their use may, at present, be recommended only as an alternative for the cases of therapeutic failure or severe intolerance when the usual schedules are used.

Our data indicate a very high primary resistance rate towards the most used antibiotics in H. pylori isolates. The efficacy of standard eradication therapies is expected to further decrease in the next years.
