Nuevas modalidades terapéuticas en el uso de teicoplanina / [New therapeutic strategies with teicoplanin]

Teicoplanin is a glycopeptide antibiotic with similar spectrum to vancomycin. However, unlike this drug, teicoplanin can be administered by i.v. or i.m. route once daily thanks to its long half-life (88 to 182 hours). This pharmacokinetic characteristic is particularly interesting in infections that require extended antimicrobial therapy, where new therapeutic strategies may be considered. Long-term treatment with teicoplanin proved effective in the treatment of bone and joint infections due to methicillin-resistant staphylococci. Teicoplanin administered three times a week yields comparable clinical efficacy than daily administration with considerably improved cost-effectiveness. This aspect merits special attention, particularly when evaluating prolonged outpatient antibiotic therapy regimens. For synergic effects it is possible to associate teicoplanin with other antibiotics. Chronic suppressive antibiotic therapy with teicoplanin may be an alternative in carefully selected patients, particularly those carrying prosthetic devices.

Tratamiento medico exitoso de una endocarditis en valvula protesica por Candida tropicalis / Successful medical treatment of Candida tropicalis in prosthetic valve endocarditis

La curación sin cirugía de la endocarditis micótica en válvula protésica es raramente descripta. Comunicamos un caso de endocarditis por Candida tropicalis sobre una prótese biológica en posición tricuspídea, en la que se consideró que la cirurgía estaba contraindicada. Se había identificado una gran vegetación sobre la prótesis biológica. Se inició tratamiento antimicótico, observándose mejoría progressiva del cuadro y desaparición de la vegetación a lo largo de 15 meses de seguimiento. El tratamiento completó 2 gr de anfotericina B para continuar luego con fluconazol. Nuestra paciente representa el primer caso de endocarditis en válvula protésica por Candida tropicalis que sobrevive sin cirugía. (AU)

Teicoplanina en el tratamiento de las infecciones osteoarticulares por Staphylococcus meticilino-resistente. Experiencia en adultos / Teicoplanin in the treatment of bone and joint infections due to methicillin resistant staphylococci. Experience in adult patients

We retrospectively evaluated 89 episodes of bone and joint infections due to methicillin-resistant staphylococci: 56 chronic osteomyelitis (CO), 10 septic arthritis (SA) and 23 infections associated to arthroplasties (IAA). We analyzed the efficacy of Teicoplanin (T) in three times a week or daily administration schemes and adequate surgery (AS). Also, we determined cost savings derived from outpatient parenteral antibiotic therapy (OPAT). The overall efficacy of T in CO and both in cases with and without implants, was higher when antibiotic therapy was associated to AS (86 vs. 46, p = 0.001; 100 vs. 33, p = 0.0049 and 76 vs. 50, p = 0.09). All SA were cured. The overall efficacy of T was higher in IAA with implant removal vs. surgical debridement (100 vs. 54, p = 0.045). In all cases, T was similarly effective when administered three times a week vs. daily administration, when associated to AS. The savings derived from OPAT were 897 days/bed and USS 179,400. Adverse effects were few and light (8 episodes, 9). The results obtained are similar to those published in the literature and show that T administered daily or in a three times a week scheme and associated to AS, is effective and safe for the treatment of bone and joint infections. The savings derived from OPAT, mainly related to reduced hospitalization, are significant in these pathologies, which usually require long treatment periods (AU)
