Case Report: Disseminated Paracoccidioidomycosis and Strongyloides Hyperinfection in a Patient with Human T-Lymphotropic Virus Type 1/2 Infection.

Co-occurrence of paracoccidioidomycosis and strongyloidiasis in immunosuppressed patients, particularly those infected with human T-lymphotropic virus type 1/2, is infrequent. We describe the case of a Peruvian farmer from the central jungle with human T-lymphotropic virus type 1/2 infection, with 2 months of illness characterized by respiratory and gastrointestinal symptoms associated with fever, weight loss, and enlarged lymph nodes. Strongyloides stercoralis and Paracoccidioides brasiliensis were isolated in sputum and bronchoalveolar lavage samples, respectively. The clinical evolution was favorable after the patient received ivermectin and amphotericin B. We hypothesize that autoinfestation by S. stercoralis in human T-lymphotropic virus type 1/2-infected patients may contribute to the disseminated presentation of Paracoccidioides spp. Understanding epidemiological context is crucial for suspecting opportunistic regional infections, particularly those that may coexist in immunosuppressed patients.

Síndrome retroviral agudo manifestado como encefalitis y ataxia cerebelosa: reporte de caso y revisión de la literatura / Acute retroviral syndrome presenting as encephalitis and cerebellar ataxia: case report and literature review

RESUMEN El síndrome retroviral agudo (SRA) es uno de los escenarios clínicos posibles en los estadios tempranos de la infección por VIH, con presentaciones variables caracterizadas por alta carga viral y manifestaciones sintomáticas inespecíficas. Se describe el caso de un paciente varón de 21 años que presentó encefalitis aguda y ataxia cerebelosa, en cuyo estudio se diagnosticó infección por VIH y se identificó el cuadro de SRA.

ABSTRACT Acute retroviral syndrome (ARS) is one of the possible clinical configurations in the early stages of HIV infection, with varying presentations, characterized by high viral copies and nonspecific symptoms. We describe the case of a 21-year-old man who presented an acute onset encephalitis and cerebellar ataxia which led to the diagnosis of HIV infection and the identification of ARS.

Otitis externa maligna con diseminación hematógena de Pseudomonas aeruginosa resistente a carbapenémicos

Pseudomonas aeruginosa en una bacteria Gram negativa no fermentadora que produce diversos tipos de infecciones severas en inmunocompetentes e inmunodeprimidos. Una de estas infecciones es la otitis externa maligna, la cual se presenta principalmente en personas con diabetes mellitus y puede tener una evolución tórpida cursando con osteomielitis de base de cráneo y parálisis de nervios craneales. El tratamiento es individualizado y principalmente conservador con antibioticoterapia guiada por cultivo. La bacteria aislada en la mayoría de los casos reportados es sensible a los antibióticos anti-pseudomónicos. Reportamos un caso de presentación inusual de otitis externa maligna por Pseudomonas aeruginosa resistente a carbapenémicos con evidencia sugerente de compromiso bilateral y en el cual se aisló al mismo germen en urocultivo y hemocultivos, lo que indicaría una diseminación hematógena del microorganismo.

Pseudomonas aeruginosa is a non-fermenting Gram-negative bacterium that produces several types of severe infections in immunocompetent and immunosuppressed patients. One of these infections is malignant otitis externa, which occurs mainly in people with diabetes mellitus and can have a torpid evolution coursing with osteomyelitis of skull base and cranial nerve palsies. Treatment is individualized and mainly conservative with culture-guided antibiotic therapy, with isolated pseudomonas being sensitive to anti-pseudomonal antibiotics in the majority of reported cases. We report a case of unusual presentation of malignant otitis externa caused by Pseudomonas aeruginosa resistant to carbapenems with suggestive evidence of bilateral involvement and in which the same germ was isolated in urine and blood cultures, which would indicate hematogenous dissemination of the microorganism.

Oligosymptomatic diphtheria infection in adults: two contacts of the Peruvian index case after 20 years without disease report.

In Peru, diphtheria infection was eradicated in the last two decades. However, recently, diphtheria pharyngeal infection was confirmed and reported in a 5-year-old boy (index case). We report two more cases of this outbreak (in the index case parents) with confirmed diphtheria infection and tox gene identified by molecular assay, who were in close contact with the index case and never presented any symptoms. Both parents had a congestive pharynx with erythematous plaques at the back of it. In adults, diphtheria infection can be oligosymptomatic or mimic viral pharyngitis, which could lead to misdiagnosis and, furthermore, an increased risk of transmission in regions with lower immunization rates.

Uso de antibióticos en pacientes internados en un hospital nacional de Lima, Perú / Use of antibiotics in inpatients from a national hospital in Lima, Peru

RESUMEN Objetivo: Determinar la prevalencia puntual y características del uso de antibióticos en distintas salas de hospitalización del Hospital Nacional Dos de Mayo. Materiales y métodos: Se realizó un estudio transversal de tres semanas de duración mediante un abordaje censal de los pacientes hospitalizados, con o sin régimen antibiótico (bajo la metodología de la Organización Mundial de la Salud) para determinar la prevalencia puntual sobre el uso de antibióticos. Resultados: Se identificaron 358 pacientes, la media de edad fue de 49 años y desviación estándar de 25,3 y fueron predominantemente adultos (88%). El uso de antibióticos fue del 51,7%; solo el 57,3% de prescripciones siguió pautas basadas en guías de práctica clínica para indicación antibiótica, mientras que el 28,5% no seguían ninguna recomendación estandarizada. Las terapias fueron empíricas en el 86,8% de pacientes y dirigidas en el 13,2%. Conclusión: En más del 50% de los pacientes hospitalizados se utilizaron antibióticos. Sin embargo, cerca de la tercera parte de prescripciones no seguían una indicación basada en alguna guía de práctica clínica. A pesar de existir un programa de control de antimicrobianos en el hospital, aún requiere optimizarse el uso adecuado de antimicrobianos.

ABSTRACT Objective: To determine the point prevalence and characteristics of antibiotic use in different hospitalization areas of the Hospital Nacional Dos de Mayo. Materials and methods: We carried out a 3-week cross-sectional study with a census approach (using methodology from the World Health Organization) to determine the point prevalence of antibiotic use in inpatients from hospitalization areas, regardless of whether or not they were on an antibiotic regimen. Results: We identified 358 patients, with a mean age of 49 (± 25.3) years, predominantly adults (88%). Antibiotics were used in 51.7% of the hospitalized patients; only 57.3% of the prescriptions followed a regimen based on clinical practice guidelines for antibiotic treatment, while 28.5% did not follow any standardized recommendation. Therapies were empirical in 86.8% and directed in 13.2% of the cases. Conclusions: Antibiotics were used in more than 50% of hospitalized patients. However, about one third of the prescriptions were not based on any clinical practice guidelines. Despite the existence of an antimicrobial control program in the hospital, appropriate antimicrobial use still needs to be optimized.

Lateral amyotrophic sclerosis-like onset after combined antiretroviral treatment initiation.

Motor neuron disease (MND) have an incidence of 2 in 100 000 persons, resulting in the death of 1 in every 500 people affected. The most common disease in MND spectrum is amyotrophic lateral sclerosis (ALS). We describe the case of an ALS-like syndrome in a HIV patient. This case report presents a 38 years old male from Peru with HIV who after 2 months of combined antiretroviral treatment (cART) initiation was admitted to the hospital for spastic paraplegia. On his first admission, rapid plasma reagent (RPR) was positive and he was treated for neurosyphilis and discharged. Nevertheless, one month after, he was admitted for the second time because paraplegia persisted. Laboratory tests, electromyography and imaging were performed, and ALS was diagnosed. Normally, HIV treated patient with ALS tend to have a better prognosis, however this was not the case. In this case report, we discuss possible association between ALS and immune reconstitution inflammatory syndrome in HIV patients.

Hospital-acquired SARS-CoV-2 pneumonia in a person living with HIV.

We report the case of a 38 year-old man living with well-controlled HIV on antiretroviral therapy who developed cerebellar symptoms and was admitted to hospital for management of an intraventricular cryptococcoma. During his hospital stay he contracted SARS CoV-2 infection within the hospital setting with a fatal outcome.

Lepra: sospecha diagnóstica en área no endémica. Serie de casos y revisión de la literatura / Leprosy: a suspected diagnosis in a non-endemic area. Case series and literature review

RESUMEN La lepra es una enfermedad crónica granulomatosa causada por el bacilo Mycobacterium Leprae que afecta piel y células de Schwann. En zonas no endémicas el diagnóstico de lepra suele ser dificultoso debido a la baja sospecha clínica. Durante el periodo de 2012 al 2019, se diagnosticaron y trataron tres casos de lepra en el servicio de infectología del Hospital Nacional Dos de Mayo. El tiempo de enfermedad promedio fue 4 años. Los pacientes iniciaron con pápulas pruriginosas en regiones corporales específicas, progresando a nódulos generalizados. Se constató parestesia e hipoestesia táctil, térmica, dolorosa y vibratoria; las cuales progresaron a anestesia. El diagnóstico se realizó mediante baciloscopía en secreción linfática y biopsia de nódulos cutáneos. Se describen las características clínicas de cada uno de los pacientes. Se remarca la importancia de la sospecha diagnóstica de esta entidad desatendida en áreas no endémicas.

ABSTRACT Leprosy (Hansen's disease) is a chronic granulomatous condition caused by Mycobacterium leprae, a microorganism that affects the skin and Schwann's cells. Making a diagnosis of this condition is difficult in non-endemic areas because of low clinical suspicion. During the 2012-2019 time period, three cases of Hansen's disease were diagnosed and treated in the ID service of Dos de Mayo Hospital. The average time history of the disease was 4 years. Patients started their condition with the appearance of pruriginous papular lesions affecting specific body regions, progressing to generalized nodular lesions. Paresthesia and tactile, thermal, pain, and vibratory hypoesthesia were found. These manifestations later progressed to anesthesia. Diagnosis was made through bacilloscopy in lymphatic fluid and skin node biopsy. Clinical features for each patient are also described. We emphasize the importance of clinical suspicion for diagnosing this unattended disease in non-endemic areas.

The emergence of Enterobacteria producing carbapenemases of type New Delhi Metalo beta-lactamases (NDM), >represent, today, a real problem of world public health. The presence of this resistance mechanism limits or nullifies the therapeutic options to combat these bacteria. In Latin America, the figures are getting higher, as they are reported in Guatemala, Colombia, Chile, Argentina, among others. Peru has not, to date, described the presence of this resistance pattern; however for several years it has been presumed to exist. Nine cases of Klebsiella pneumoniae NDM are described, as infectious or colonizing agents, in critically ill patients, mostly with neurosurgical pathology, of Hospital Nacional Dos de Mayo in Lima - Peru. The patients in the series described below represent the first reports of Klebsiella pneumoniae NDM in Peru.
