RESUMO

Hepatitis C virus still represents a major cause of morbidity and mortality worldwide. In Peru, two national practice guidelines for the management of this infection were published more than 5 years ago; however, the latest breakthroughs in the treatment make it necessary to update these guidelines. We reviewed the most recent recommendations of the international guidelines and compared them with the current Peruvian guidelines. We found major differences, such as the use of Glecaprevir/Pibrentasvir as a first-line therapy, which is contemplated in the World Health Organization guideline, and recommended by American and European guidelines, but is not considered in the Peruvian guidelines. Another crucial difference lies in the management of patients with chronic kidney disease, who are treated nowadays with a variety of direct-acting antivirals, with no restrictions on the use of Sofosbuvir-based regimens in first-world countries, an approach that has not been adopted in Peru. We believe that standardization of the recommendations of the Peruvian guidelines is imperative, including the new therapeutic strategies that have emerged in recent years. We also suggest conducting a cost effectiveness analysis in the Peruvian context to allow for the implementation of new antivirals, and to achieve a better control of hepatitis C in the country.

RESUMO

Neurobrucellosis, caused by Brucella species, is a zoonotic infection that may involve the central nervous system. Although uncommon, it can manifest as a solitary intracranial mass. We report a case of neurobrucellosis in a 25-year-old woman from Peru who presented with headache, weight loss, and right-side hemiparesis and paresthesia. A contrast-enhanced magnetic resonance imaging scan revealed an intracerebral mass in the left temporal lobe. Serum testing subsequently were positive. Brain biopsy demonstrated non-necrotizing granulomas without malignant cells. Neurobrucellosis should be considered in the differential diagnosis of brain space occupying lesions in endemic countries.

RESUMO

RATIONALE: Lemierre-like syndrome (LLS) is characterized by bacteremia, septic thrombophlebitis of the internal jugular vein, and metastatic abscesses. In contrast to classic Lemierre syndrome, sources of infection are not related to oropharyngeal infections, as are frequent soft tissue infections. In recent years, Staphylococcus aureus has been identified as an emergent pathogen that causes this syndrome. The mortality rate of LLS caused by this pathogen is approximately 16%. Timely diagnosis, antibiotic treatment, and infection control are the cornerstones to treat LLS. Anticoagulant therapy as adjuvant treatment remains controversial. PATIENT CONCERNS: A 31-year-old woman from California, United States (US), was admitted to the emergency room with a history of 2 days of fever and severe throbbing pain in the left cervical region. Thorax and neck CT tomography revealed confluent cavities suggestive of septic embolism in the lungs and a filiform thrombus in the lumen of the left internal jugular vein, with moderate swelling of the soft and muscular tissues. Methicillin-resistant Staphylococcus aureus (MRSA) was isolated from the blood culture. DIAGNOSIS: The thrombus in the internal jugular vein associated with cellulitis in the neck and multiple cavitary lesions in the lungs support the diagnosis of LLS caused by MRSA with septic embolization. INTERVENTIONS: During treatment, the patient received vancomycin IV for 25 days and returned to the US with linezolid orally. In addition, assisted video-thoracoscopy and bilateral mini-thoracotomy with pleural decortication were performed for infectious source control, where 1700cc of purulent pleural fluid was drained. OUTCOMES: The patient was discharged with optimal evolution. LESSONS: LLS should be suspected in patients with skin and soft tissue infections who develop thrombosis or metastatic infections. MRSA infections should be considered in patients from areas where this pathogen is prevalent.

RESUMO

Objective: This scoping review aimed to describe studies that evaluate the management of cryptococcal meningitis (CM) using cerebrospinal fluid (CSF) shunts, types of shunts used, and clinically relevant patient outcomes. Methods: We searched in the following databases: PubMed, Web of Science/Core collection, Embase, the Cochrane Library, and clinicaltrials.gov on 1 April 2022. We included two-arm and one-arm cohort studies that evaluated clinically relevant patient outcomes. Case reports were used to describe the type of CSF shunts used and the rationale behind its selection. The selection and extraction processes were independently performed by two authors. Results: This study included 20 cohort studies and 26 case reports. Only seven cohort studies compared two groups. Ventriculoperitoneal shunt was the most commonly used type of shunt (82.1%). The main indications for placing a shunt were persistently high opening pressure (57.1%) and persisting neurological symptoms or deterioration (54.3%). Cohort studies suggest that patients with shunt showed improvement in some outcomes such as neurological symptoms and hospital stay length. The most common shunt complications were post-operative fever (1-35.6%) and shunt obstruction (7-16%). Conclusion: CSF shunts may improve some clinically relevant outcomes in patients with CM, but the evidence is very uncertain.

RESUMO

OBJECTIVES: To evaluate the efficacy of antituberculosis therapy on pregnancy outcomes in infertile women with genital tuberculosis. DESIGN: Systematic review. DATA SOURCES: We searched in PubMed/MEDLINE, CENTRAL and EMBASE up to 15 January 2023. Additionally, we manually search the reference lists of included studies. ELIGIBILITY CRITERIA: We included randomised controlled trials (RCT), non-RCTs (non-RCT) and cohort studies that evaluated the effects of antituberculosis treatment on pregnancy outcomes in infertile women with genital tuberculosis compared with not receiving antituberculosis treatment or receiving the treatment for a shorter period. DATA EXTRACTION AND SYNTHESIS: Two independent reviewers extracted data. We used Cochrane Risk of Bias 1.0 and Risk Of Bias In Non-randomised Studies tools for risk of bias assessment and meta-analysis was not performed. We used Grading of Recommendations, Assessment, Development and Evaluations approach to assess the certainty of the evidence. RESULTS: Two RCTs and one non-RCT were included. The antituberculosis regimens were based on isoniazid, rifampicin, pyrazinamide and ethambutol for 6-12 months. In women without structural damage, very low certainty of evidence from one RCT showed that the antituberculosis treatment may have little to no effect on pregnancy, full-term pregnancy, abortion or intrauterine death and ectopic pregnancy, but the evidence is very uncertain. In women with structural damage, very low certainty of evidence from one non-RCT showed that the antituberculosis treatment may reduce the pregnancy rate (297 fewer per 1000, 95% CI -416 to -101), but the evidence is very uncertain. In addition, very low certainty of evidence from one RCT compared a 9-month vs 6-month antituberculosis treatment regimen showed similar effects between the schemes, but the evidence is very uncertain. Two RCTs reported that no adverse events of antituberculosis treatment were noted or were similar in both groups. CONCLUSION: The effect of antituberculosis treatment on pregnancy outcomes in infertile women with genital tuberculosis is very uncertain. PROSPERO REGISTRATION NUMBER: CRD42022273145.

RESUMO

INTRODUCTION: In the context of the COVID-19 pandemic, information on factors associated with adherence to antituberculosis treatment in areas with high prevalence of tuberculosis is scarce. OBJETIVE: To evaluate whether there is an association between social support, concern about COVID-19 infection and knowledge about tuberculosis, and non-adherence to antituberculosis treatment. MATERIALS AND METHODOS: A cross-sectional study was carried out on patients under antituberculosis treatment, from January to March, 2022, in centers located in areas with a high prevalence of tuberculosis in Lima. We used the Morisky Green-Levine questionnaire to assess adherence to treatment as the dependent variable; the independent variables were evaluated using the Medical Outcomes Study Social Support Survey for perceived social support and concern about COVID-19 infection, and the Battle Test to assess patients' knowledge about their disease. We used Poisson regression with robust variance to evaluate the association between the independent variables and the dependent one. RESULTS: Out of 101 participants (73.3% male with an average age of 35.1 ± 16 years), 51.5% were non-adherent to antituberculosis treatment. Medium or high level of concern about getting COVID-19 was associated with a higher prevalence of non-adherence to treatment (odds ratio: 1.68; 95 % confidence interval: 1.09-2.57) (adjusted for considered confounding variables). CONCLUSIONS: Non-adherence is a frequent condition among patients living in an area with a high prevalence of tuberculosis in Lima, especially among those with a higher concern for COVID-19 infection.

Introducción: En el contexto de la pandemia por la COVID-19 es escasa la información de factores asociados al cumplimiento del tratamiento antituberculoso en las zonas de alta prevalencia de tuberculosis. Objetivo: Evaluar si existe asociación entre el apoyo social, la preocupación por el contagio de COVID-19 y el conocimiento de la tuberculosis, frente al incumplimiento del tratamiento antituberculoso. Materiales y métodos: Se trata de un estudio transversal de pacientes en tratamiento antituberculoso durante los meses de enero a marzo del 2022 en centros ubicados en áreas de alta prevalencia de tuberculosis en Lima. Se utilizó el cuestionario de Morisky Green-Levine para evaluar el cumplimiento del tratamiento como variable dependiente; las variables independientes se evaluaron usando el Medical Outcomes Study Social Support Survey para determinar el apoyo social percibido y la preocupación por la infección de COVID-19, y el test de Batalla para evaluar el conocimiento del paciente sobre su enfermedad. Se utilizó la regresión de Poisson con varianza robusta para determinar la asociación entre las variables. Resultados: De un total de 101 participantes (73,3 % hombres y edad media 35,1 ± 16 años), el 51,5 % no observaron el tratamiento antituberculoso. El nivel de preocupación medio o alto de contagiarse y desarrollar COVID-19 se asoció con una mayor prevalencia de incumplimiento del tratamiento (razón de prevalencia: 1,68; intervalo de confianza del 95 %: 1,09-2,57) (ajustada por las variables de confusión consideradas). Conclusiones: El incumplimiento del tratamiento antituberculoso es una condición frecuente entre los pacientes de una zona de alta prevalencia de tuberculosis en Lima especialmente entre aquellos con mayor preocupación al contagio por el virus de SARSCoV-2, causante de la COVID-19.

RESUMO

Vaccination against mpox can control the outbreak by targeting high-risk groups such as the LGBTIQ+ community. The aim of the study was to evaluate the perceptions and intentions to get vaccinated against mpox among the LGBTIQ+ community in Peru. We conducted a cross-sectional study from 1 November 2022 to 17 January 2023 in Peru. We included individuals over 18 years old, belonging to the LGBTIQ+ community, and residing in the departments of Lima and Callao. To evaluate the factors associated with the intention to be vaccinated, we used Poisson regression with robust variance to create a multivariate model. The study comprised 373 individuals who self-identified as members of the LGBTIQ+ community. The participants had a mean age of 31 years (SD ± 9), with 85.0% males and 75.3% reporting to be homosexual men. The majority (88.5%) expressed their intention to receive the vaccine against mpox. Believing that the vaccine is safe was associated with a higher intention to be vaccinated (aPR: 1.24; 95% CI: 1.02 to 1.50; p = 0.028). Our study population showed a high level of mpox vaccination intent. Educational campaigns reinforcing the concept of vaccine safety should be conducted to increase the intention and possibly the vaccination rate in the LGBTIQ+ community.
