Ceftolozane/tazobactam for Pseudomonas aeruginosa pulmonary exacerbations in cystic fibrosis adult patients: a case series.

Management of cystic fibrosis (CF) patients colonized with Pseudomonas aeruginosa is challenging due to its virulence and multi-drug resistance. Ceftolozane/tazobactam (C/T) is a promising new antipseudomonal agent, and clinical data on CF are limited. We describe our experience in the use of C/T for P. aeruginosa-related pulmonary exacerbations (PE) in CF adults admitted within 2016 and 2019 at Careggi Hospital, Florence, Italy. PE was diagnosed as deterioration of respiratory function, worsening cough, and increasing of sputum. C/T was given at the dose of 3 g every 8 h. C/T was used in ten patients. Mean length of C/T treatment was 16.3 days, and tobramycin was the most frequently combined antipseudomonal agent. All patients were successfully treated although susceptibility testing on sputum sample showed C/T resistance in two cases. No adverse effects related to C/T were reported. To our knowledge this is the largest case series on CF patients treated with C/T. Clinical responses were encouraging even where C/T resistant P. aeruginosa was isolated, probably due to multiple phenotypes colonizing CF lungs. C/T could play a promising role in combination therapy against P. aeruginosa as a part of a colistin-sparing regime.

Scaling down of a deworming programme among school-age children after a thirty-year successful intervention in the Bolivian Chaco.

OBJECTIVE: Preventive chemotherapy is the WHO-recommended control method for soil-transmitted helminthiases. In the Bolivian Chaco, 6-monthly single-dose mebendazole delivery to school-age children achieved a dramatic decrease in soil-transmitted helminthiases prevalence between 1987 and 2013. Consequently, in September 2016, preventive chemotherapy delivery was interrupted in nine rural communities. In compliance with WHO recommendations, we intensified surveillance to monitor soil-transmitted helminthiases prevalence and detect potential changes that would require interventions. METHODS: We conducted two cross-sectional parasitology surveys 12 months apart (September 2016-2017) among school-age children living in the communities where preventive chemotherapy delivery had been halted. Study design, methods of sampling and sample analysis technique (direct microscopy, Kato-Katz technique) followed WHO recommendations, aiming to obtain data representative of the Bolivian Chaco ecological zone. RESULTS: We collected 426 samples in 2016 and 520 in 2017. Soil-transmitted helminthiasis prevalence was unremarkable: 0.7% (95% CI 0-1.5%) in 2016 and 0.8% (0-1.5%) in 2017. Conversely, the prevalence of tapeworms (13% in 2016, 12% in 2017) and intestinal protozoan infections (81% in 2016 and 75% in 2017) continued to be high. CONCLUSIONS: Our findings support the role of preventive chemotherapy in reducing soil-transmitted helminthiases transmission, as otherwise poor hygienic and health conditions persist in the Bolivian Chaco. A national survey, involving areas from all the ecological zones of Bolivia, is now warranted.

Sociocultural dimension of epilepsy: an anthropological study among Guaraní communities in Bolivia--an International League Against Epilepsy/International Bureau for Epilepsy/World Health Organization Global Campaign against Epilepsy regional project.

This study was performed to analyze sociocultural beliefs about epilepsy among Guaraní communities in Bolivia. People with epilepsy, their family members, the general population, and local health care personnel were interviewed about the meaning of and beliefs, feelings, and practices concerning epilepsy. Epilepsy is called mano-mano, a term that means being in a constant passage between life and death. The disease is attributed mainly to a failure to observe a fasting period and to other eating habits. Natural remedies are the most recommended treatments even though half of respondents reported that antiepileptic drugs may be effective. The concept of epilepsy as an embodied disease with natural causes appears to differ from that documented in other traditional societies. People with epilepsy do not represent a threat to the community, which seems to have an attitude aimed at their protection. Moreover, people from these communities appear to favor a combination of biomedical and traditional care systems.
