Consenso Mexicano para el Tratamiento de la Hepatitis C / The Mexican consensus on the treatment of Hepatitis C

El objetivo del Consenso Mexicano para el Tratamiento de la Hepatitis C fue el de desarrollar un documento como guía en la práctica clínica con aplicabilidad en México. Se tomó en cuenta la opinión de expertos en el tema con especialidad en: gastroenterología, infectología y hepatología. Se realizó una revisión de la bibliografía en MEDLINE, EMBASE y CENTRAL mediante palabras claves referentes al tratamiento de la hepatitis C. Posteriormente se evaluó la calidad de la evidencia mediante el sistema GRADE y se redactaron enunciados, los cuales fueron sometidos a voto mediante un sistema modificado Delphi, y posteriormente se realizó revisión y corrección de los enunciados por un panel de 34 votantes. Finalmente se clasificó el nivel de acuerdo para cada oración. Esta guía busca dar recomendaciones con énfasis en los nuevos antivirales de acción directa y de esta manera facilitar su uso en la práctica clínica. Cada caso debe ser individualizado según sus comorbilidades y el manejo de estos pacientes siempre debe ser multidisciplinario.

The aim of the Mexican Consensus on the Treatment of Hepatitis C was to develop clinical practice guidelines applicable to Mexico. The expert opinion of specialists in the following areas was taken into account: gastroenterology, infectious diseases, and hepatology. A search of the medical literature was carried out on the MEDLINE, EMBASE, and CENTRAL databases through keywords related to hepatitis C treatment. The quality of evidence was subsequently evaluated using the GRADE system and the consensus statements were formulated. The statements were then voted upon, using the modified Delphi system, and reviewed and corrected by a panel of 34 voting participants. Finally, the level of agreement was classified for each statement. The present guidelines provide recommendations with an emphasis on the new direct-acting antivirals, to facilitate their use in clinical practice. Each case must be individualized according to the comorbidities involved and patient management must always be multidisciplinary.

Clinical manifestations and immunodiagnosis of gnathostomiasis in Culiacan, Mexico.

Gnathostomiasis was first described in Mexico in 1970, and endemic areas have been spreading in six states of this country. In Culiacan, Sinaloa, 300 cases of cutaneous larva migrans were recorded between January 1992 and December 1995. In addition, a Gnathostoma larva was surgically removed from the eye of one patient. Cutaneous lesions were observed mainly on the face, neck, arms, and legs. About 70% of the patients showed eosinophilia. A skin biopsy was carried out on 35 patients and the parasite was identified in histopathologic sections of 12 of these patients. In four patients, the larva migrated out spontaneously from the skin. An enzyme-linked immunosorbent assay using a crude somatic extract of adult Gnathostoma doloresi worms showed that 93% of the patients were seropositive, confirming the reliability of clinical diagnosis. A total of 14 advanced third-stage Gnathostoma larvae were found in four species of ichthyophagous birds captured on dams and dikes near the city of Culiacan. Scanning electron micrographs of human and bird larvae showed that they were morphologically indistinguishable from G. spinigerm. We conclude that the life cycle of Gnathostoma has been established in Sinaloa, and has become a serious public health issue for residents.

Safety and efficacy of lomefloxacin and cefaclor in the treatment of skin and skin structure infections.

The purpose of this study was to compare the safety and efficacy of lomefloxacin with that of cefaclor in the treatment of adult secondary bacterial skin and skin structure infections. The study was conducted as a randomized, single-blind comparison. Eighty patients enrolled in the study, of which 74 were evaluable: 37 patients in the lomefloxacin group and 37 in the cefaclor group. Patients received either 400 mg of lomefloxacin orally once daily or 250 mg of cefaclor orally three times daily for 12 days. The most frequent pathogens isolated included Staphylococcus aureus, Streptococcus pyogenes, coagulase-negative staphylococci, and Escherichia coli. The clinical response was similar in both groups (89.1%). The bacteriologic eradication rate was 100% in the lomefloxacin group and 94.5% in the cefaclor group. Adverse events were minimal. Once-daily lomefloxacin is a safe and effective treatment for secondary bacterial skin and skin structure infections caused by susceptible pathogens.

Comparison of the safety and efficacy of lomefloxacin and trimethoprim/sulfamethoxazole in the treatment of uncomplicated urinary tract infections: results from a multicenter study.

Lomefloxacin, a new difluorinated quinolone, and trimethoprim/sulfamethoxazole (TMP/SMX) were compared in the treatment of adults with uncomplicated urinary tract infections. The study was conducted as a multicenter, controlled, prospectively randomized, single-blind study in five countries (Argentina, Belgium, Brazil, Mexico, and Venezuela). A total of 254 patients were enrolled: 129 in the lomefloxacin group and 125 in the TMP/SMX group. Patients received either 400 mg lomefloxacin orally once daily or 160 mg/800 mg TMP/SMX orally twice daily for 7-10 days. Escherichia coli and Proteus mirabilis were the pathogens most frequently isolated. At 5-9 days post-therapy, satisfactory bacteriologic results were noted in 98.4% of patients treated with lomefloxacin and in 95.8% of patients in the TMP/SMX group (p = 0.2153). Clinical success 5-9 days post-therapy was noted in 99.2% of patients in the lomefloxacin group and in 98.3% of patients in the TMP/SMX group (p = 0.5138). Adverse events probably related to treatment occurred in 6% of those treated with lomefloxacin and in 7% of patients treated with TMP/SMX. Once-daily oral lomefloxacin is a well-tolerated and effective treatment of uncomplicated urinary tract infections caused by susceptible pathogens.
