Prevalencia del síndrome del edificio enfermo en trabajadores de la industria manufacturera / Prevalence of sick building syndrome in manufacturing industry workers

El síndrome del edificio enfermo, se refiere a un conjunto de síntomas generales en mucosa (ocular y/o respiratoria) y piel que presentan los ocupantes de edificaciones con calidad ambiental deficientes, exponiendo a sus ocupantes a factores de riesgos físicos, mecánicos, químicos, biológicos y psicosociales, que puede afectar negativamente la salud y productividad de las personas. Con el propósito de determinar la frecuencia de los síntomas de los ocupantes de una industria manufacturera del Perú, se realizó estudio transversal aplicándose a 237 trabajadores, estratificados por áreas laborales, el cuestionario sugerido por el Instituto Nacional de Higiene y Seguridad en el Trabajo, además de evaluar la condición ambiental mediante la determinación de bioaerosoles cultivables y contables. Los resultados mostraron prevalencia superior al 20% en síntomas como: sequedad en ojos y garganta, picor en garganta congestión nasal, dolor de cabeza y debilidad general. Se tomaron, cuantificaron y caracterizaron 164 muestras de bioaerosoles, los microrganismos encontrados con mayor porcentaje fueron, Aspergillus sp. 54,68% (68) en el área administrativa, mientras que en las áreas de producción y almacén predomino Penicillium sp. con 87,10% (108) y 62,21% (77) respectivamente. Otros géneros encontrados en mayor porcentajes, en las tres áreas fueron: Trichoderma, Acremonium, Monilia, Cladosporium, entre otros. Los hallazgos se correlacionan con lo reportado en diversas investigaciones, la presencia de mencionados hongos, sugiere que existe una inadecuada calidad ambiental y aunada a la prevalencia obtenida en cuanto a sintomatología, se puede clasificar la edificación objeto de estudio con el Síndrome del edificio enfermo(AU)

Sick building syndrome refers to a set of general mucosal (ocular and/or respiratory) and skin symptoms presented by occupants of buildings with poor environmental quality, exposing their occupants to physical, mechanical, chemical, biological and psychosocial, which can negatively affect the health and productivity of people. In order to determine the frequency of the symptoms of the occupants of a manufacturing industry in Peru, a cross-sectional study was carried out, applying to 237 workers, stratified by work areas, the questionnaire suggested by the National Institute of Hygiene and Safety at Work, in addition to to evaluate the environmental condition by determining cultivable and countable bioaerosols. The results showed a prevalence greater than 20% in symptoms such as: dry eyes and throat, itchy throat, nasal congestion, headache and general weakness. 164 samples of bioaerosols were taken, quantified and characterized, the microorganisms found with the highest percentage were Aspergillus sp. 54.68% (68) in the administrative area, while in the production and storage areas, Penicillium sp. with 87.10% (108) and 62.21% (77) respectively. Other genera found in higher percentages in the three areas were: Trichoderma, Acremonium, Monilia, Cladosporium, among others. The findings correlate with what has been reported in various investigations, the presence of these fungi suggests that there is an inadequate environmental quality and, together with the prevalence obtained in terms of symptoms, the building under study can be classified with the Sick Building Syndrome(AU)

Clinical neglect of aspergillosis in pulmonary tuberculosis co-infection: a case report of avoidable mortality in a resource-constrained setting

Background: Pulmonary aspergillosis (PA) is common among patients with tuberculosis (TB). With both infections presenting with similar clinical and radiologic features, diagnosis of PA is often made too late or missed completely due to lack of clinical suspicion and poor diagnostic laboratory capacity for mycotic infections prevalent in our settings. We present a case of preventable mortality caused by delayed diagnosis and treatment of PA in a patient with pulmonary TB (PTB). Case presentation: A 13-year-old female was diagnosed and treated for PTB, having received anti-TB regimen for 8 months in a mission hospital from where she was referred due to worsening cough, chest pain and progressive breathlessness. The patient was re-assessed and investigated, with GeneXpert detecting Mycobacterium tuberculosis, susceptible to rifampicin. Diagnosis of pulmonary tuberculosis complicated by right pneumothorax was made indicating an emergency thoracotomy and chest tube insertion and continuation of the first line anti-TB regimen. At about 2 weeks into admission, patients had features of superimposed acute bacterial sepsis with fever becoming high grade, marked neutrophilia with toxic granulation and elevated sepsis biomarker, and this necessitated empiric antibiotic treatment with parenteral meropenem and vancomycin. However, the patient only had mild clinical improvement following which there was progressively worsening respiratory symptoms and massive haemoptysis. Result of sputum fungal study was available on admission day 20 and revealed a growth of Aspergillus flavus. Treatment with intravenous voriconazole was however commenced rather late when the fungal respiratory disease could no longer be remedied. The patient died on admission day 23. Conclusion: Diagnosis of PA in patients with background TB is often made too late to guarantee timely and effective antifungal treatment with negative consequences on patients' outcomes. Improving clinical and laboratory capacities is essential to reducing mortality from PA in healthcare facilities.

Aspergilosis pulmonar asociada a COVID-19: reporte de caso / Pulmonary aspergillosis associated with COVID-19: case report

La aspergilosis pulmonar clásicamente se ha considerado como una enfermedad de paciente inmunocomprometido (neoplasias hematológicas, neutropenia severa, trasplante de órgano sólido, virus de la inmunodeficiencia humana/síndrome de inmunodeficiencia adquirida VIH/SIDA) o que afecta a pacientes inmunocompetentes, pero críticamente enfermos. Sin embargo, durante la pandemia por COVID-19 el comportamiento de las infecciones fúngicas ha cambiado, siendo observada con mayor frecuencia en la actualidad. Se presenta el caso de un paciente masculino de 20 años, procedente de la Isla de San Andrés, al norte de Colombia, sin patología previa conocida, ingresa al servicio de urgencias cursando con cuadro de tres días de fiebre y tos seca. A su ingreso el paciente está consciente, con fluctuación de la atención, taquicardia y febril. Examen pulmonar y abdominal sin alteraciones. Paraclínicos con leucocitosis, neutrofilia, prueba rápida para COVID-19 negativa y NS1 para dengue negativa. La radiografía de tórax en proyección lateral evidencia infiltrados intersticiales y en tomografía, lesiones nodulares de bordes mal definidos algunos espiculados, con infiltrado intersticial vecino (depósitos tumoral o infeccioso). Resultado de RT- PCR SARSCoV-2 positivo: por hallazgos radiológicos se realiza biopsia pulmonar por toracoscopia, cuyo estudio histológico revela nódulos múltiples y estructuras fúngicas en su interior compatible con aspergillus. Se inicia terapia de primera línea con voriconazol y egreso asintomático al completar tratamiento. Se concluye que las infecciones fúngicas representan un reto diagnóstico, su retraso, por falta de sospecha en el paciente inmunocompetente impacta en la morbimortalidad. El aumento de las infecciones fúngicas durante la pandemia, obliga a considerar la aspergilosis como diagnóstico diferencial en paciente con COVID-19, con fiebre persistente y hallazgos radiológicos atípicos.

Pulmonary Aspergillosis has classically been considered a disease of immunocompromised patients (hematological neoplasms, severe neutropenia, solid organ transplantation, human immunodeficiency virus / acquired immunodeficiency syndrome HIV / AIDS) or immunocompetent but critically ill patients. However, during the COVID-19 pandemic the behavior of fungal infections has changed, being observed more frequently today. A case of 20-year-old male patient, from San Andrés islands, north of Colombia; With no known prior pathology, he was admitted to the emergency department with a 3-day fever and dry cough. On admission, a conscious patient with fluctuating attention, tachycardia and fever. Pulmonary and abdominal examination without alterations. Paraclinical patients with leukocytosis, neutrophilia, rapid test for covid19 negative and NS1 for dengue negative. The chest X-ray in lateral projection shows interstitial infiltrates and in tomography as nodular lesions with poorly defined edges, some spiculated, with neighboring interstitial infiltrate (tumor or infectious deposits). A positive SARS COV 2 RT-PCR result, due to radiological findings, a lung biopsy was performed by thoracoscopy, the histological study of which revealed multiple nodules fungal structures inside compatible with aspergillus. First-line therapy with voriconazole was started, asymptomatic discharge upon completion of treatment. As conclusion fungal infections represent a diagnostic challenge, their delay, due to lack of suspicion in the immunocompetent patient, impacts morbidity and mortality. The increase in fungal infections during the COVID-19 pandemic makes it necessary to consider aspergillosis as a differential diagnosis in a patient with COVID-19, with persistent fever and atypical radiological findings.

Aspergilosis pulmonar asociada a COVID-19 en pacientes críticos: experiencia de un hospital público chileno / COVID-19-associated pulmonary aspergillosis in critically ill patients: experience of a Chilean public hospital

INTRODUCCIÓN: Se han descrito coinfecciones fúngicas por Aspergillus spp. en pacientes críticos cursando una infección por COVID-19. OBJETIVOS: Describir las características clínicas, diagnóstico, tratamiento y evolución de pacientes con síndrome de distrés respiratorio agudo con COVID-19, que cursan con aspergilosis pulmonar asociada a COVID-19 (CAPA por sus siglas en inglés) en un centro hospitalario público. Pacientes y MÉTODOS: Revisión de registros clínicos durante 12 meses en pacientes con diagnóstico de CAPA mediante cultivos de muestras respiratorias o determinación de galactomanano (GM). RESULTADOS: En 11 pacientes se diagnosticó CAPA probable (score APACHE II promedio de 11,7). Las muestras respiratorias se obtuvieron en 73% de los casos por lavado broncoalveolar y en 27% por aspirado endotraqueal. Se aisló A. fumigatus en 4 cultivos, A. niger, A. terreus y Aspergillus spp en una ocasión cada uno y los cultivos fueron negativos en 4 muestras. En 7 pacientes se realizó GM de muestras respiratorias, mediana: 3,6 (RIC: 1,71 - 4,4), en 10 pacientes se realizó GM sérica, mediana: 0,5 (RIC: 0,265 - 0,975) con 50% de ellas > 0,5. Dos pacientes mostraron hallazgos sugerentes de CAPA en la tomografía computada. Todos recibieron terapia anti-fúngica con voriconazol, con una duración promedio 14 días. Cuatro pacientes fallecieron. CONCLUSIONES: La presencia de CAPA debe ser un diagnóstico a considerar en pacientes críticos con COVID-19.

BACKGROUND: Aspergillus spp. fungal coinfections have been described in critically ill COVID-19 patients. AIM: To describe the clinical characteristics, diagnosis, treatment and evolution of patients with acute respiratory distress syndrome with COVID-19, who present with COVID-19 associated pulmonary aspergillosis (CAPA) in a single public hospital. METHODS: Retrospective review of clinical records during 12 months in patients diagnosed with CAPA by cultures of respiratory samples or determination of galactomannan (GM). RESULTS: Probable CAPA was diagnosed in 11 patients (average APACHE II score of 11.7). Respiratory samples were obtained in 73% of cases by bronchoalveolar lavage and in 27% by tracheal aspirate. A. fumigatus was isolated in 4 cultures, A. niger, A. terreus and Aspergillus spp on one occasion each and the cultures were negative in 4 samples. Respiratory sample GM was performed in 7 patients, median: 3.6 (IQR: 1.71 - 4.4). In 10 patients, serum GM was performed, median: 0.5 (IQR: 0.265 - 0.9 75) with 50% of them > 0.5. Two patients showed classic findings suggestive of CAPA on computed tomography. All received antifungal therapy with voriconazole, mean time 14 days. Four patients died. CONCLUSIONS: The presence of CAPA should be a diagnosis to be considered in critically ill COVID-19 patients.

Clinical profile of human T-lymphotropic virus type I: a forgotten infection in pediatrics / Perfil clínico del virus linfotrópico humano tipo I: una infección olvidada en pediatría

Summary The Human T-lymphotropic virus type 1 (HTLV-1), a retrovirus with oncogenic properties, affects around ten to twenty million people worldwide. The most common disorders associated with HTLV-1 infection are T-cell leukemia/lymphoma (ALT) and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Studies have reported other clinical manifestations in HTLV-1 seropositive patients, including inflammatory disorders, co-infections with opportunistic agents, and pulmonary diseases. Objective: Here, we aim to describe a cohort of juvenile patients with confirmed HTLV-1 infection that showed clinical manifestations other than neurological symptoms. Methodology and patients: Retrospective analysis of clinical data describing background and clinical findings of 12 juvenile patients with confirmed HTLV-1 infection, attended during January 2018 to February 2020 in a pediatric referral hospital in Cali, Colombia. Results: 11 out 12 patients were from Colombia´s Pacific coast, 10 suffered from significant nutritional deficiencies. Six exhibited dermatological findings, 3 compatible with infective dermatitis. None of the cases exhibited clinical or laboratory findings suggesting ALT or HAM/TPS. Eight patients had structural lung disease assessed by chest Computed Tomography (CT) scans; 4 of them tested positive for galactomannan antigen in bronchoalveolar fluid suggesting pulmonary aspergillosis, and 2 others exhibited a positive PCR testing for tuberculosis. Three patients were diagnosed with autoimmune disorders; 1 patient with Crohn´s Diseases, 1 case of autoimmune thrombocytopenic purpura, and a patient with Vogt-Koyanagi-Harada syndrome (non-granulomatous uveitis). Conclusions: There is a broad range of clinical manifestations in pediatric HTLV-1 patients, and the clinician should consider structural pulmonary disease, opportunistic co-infections and autoimmune disorders in the diagnostic algorithm.

Resumen El Virus Linfotrópico de células T humanas tipo 1 (HTLV-1), retrovirus con propiedades oncogénicas, afecta alrededor de 10-20 millones de personas mundialmente. Las manifestaciónes más comúnmente asociadas a HTLV-1 incluyen leucemia/linfoma de células T (ALT) y mielopatía asociada a HTLV-1/ paraparesia espástica tropical (HAM/TSP). Estudios han reportado otras manifestaciones clínicas en pacientes positivos para HTLV-1, incluyendo enfermedades inflamatorias, coinfecciones con gérmenes oportunistas y enfermedad pulmonar. Objetivo: es describir clínicamente una cohorte de pacientes pediátricos con infección por HTLV-1 confirmada que presentan manifestaciones clínicas diferentes a síntomas neurológicos. Metogolodía y pacientes: Análisis retrospectivo de historia clínica describiendo procedencia y hallazgos clínicos en 12 pacientes con infección por HTLV-1 confirmada, atendidos durante el periodo de Enero de 2018 a Febrero de 2020 en un hospital pediátrico de referencia en Cali, Colombia. Resultados: Once de 12 pacientes procedían de la costa Pacífica Colombiana, 10 con deficiencias nutricionales significativas. Seis mostraron compromiso dermatológico, 3 compatibles con dermatitis infectiva. Ningún paciente presentó hallazgos clínicos o paraclínicos sugestivos de ALT o HAM/TPS. Ocho pacientes presentaron enfermedad pulmonar estructural evidenciada por TAC de tórax; 4 de ellos con antígeno galactomanan positivo en lavado broncoalveolar, sugiriendo aspergilosis pulmonar, y otros 2 resultaron con PCR positiva para tuberculosis. Tres pacientes presentaron enfermedades autoinmunes concomitantes: uno con Enfermedad de Crohn, uno con Púrpura Trombocitopénica Autoinmune, y un paciente con Síndrome de Vogt-Koyanagi-Harada. Conclusiones: Existe un amplio rango de manifestaciones clínicas en pacientes pediátricos con HTLV-1, considerando enfermedad pulmonar estructural, coinfecciones oportunistas y enfermedades autoinmunes dentro del algoritmo diagnóstico.

COVID-19 associated pulmonary aspergillosis (CAPA) in a pregnant woman

Viral or bacterial co-infections with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been reported in the literature. However, the knowledge on Aspergillus co-infection among patients with coronavirus disease 2019 (COVID-19) is limited. COVID‐19‐associated pulmonary aspergillosis (CAPA) has been seen in critically ill COVID-19 patients with acute respiratory distress syndrome (ARDS), which has raised concerns about the worsening disease course of COVID-19 and increasing mortality. We describe a clinical case of CAPA infection and acute respiratory distress syndrome (ARDS) with a deathly outcome in a previously well, non-immunocompromised pregnant woman with intrauterine death of the fetus. Hence, we suggest that clinicians and pathologists keep alerting the possible occurrence of pulmonary aspergillosis in severe/critical COVID-19 patients, and aggressive investigations should be done to rule out the possibility of CAPA so that early treatment can be administrated.

Coinfección por Mycobacterium abscessus y Mycobacterium tuberculosis en un paciente con síndrome de Cushing exógeno y otras comorbilidades / Mycobacterium abscessus and Mycobacterium tuberculosis coinfection in a patient with exogenous Cushing syndrome and other comorbilities

RESUMEN Mycobacterium abscessus es una micobacteria no tuberculosa de crecimiento rápido, que produce infección pulmonar, cutánea, diseminada y otras, sobre todo en pacientes con comorbilidades. El diagnóstico se basa en la identificación de la micobacteria por medios de cultivo o por pruebas moleculares. El tratamiento con macrólidos y amikacina continúa siendo el ideal, aunque depende de la localización y de la gravedad de la infección, sin embargo, se han identificado genes de resistencia en algunas subespecies que limitan la eficacia antibiótica. Presentamos el caso de un paciente con coinfección cutánea por Mycobacterium abscessus y Mycobacterium tuberculosis, quien presenta un síndrome de Cushing exógeno, factor predisponente para estas infecciones. Además, se identificaron hidatidosis y aspergilosis pulmonares. El tratamiento antituberculoso del paciente se ajustó para manejar ambas micobacterias, y su evolución fue favorable.

ABSTRACT Mycobacterium abscessus is a fast-growing non-tuberculous mycobacterium that causes lung, skin, disseminated and other infections, mainly in patients with comorbidities. The diagnosis is based on the identification of the mycobacterium by culture media or molecular tests. Treatment with macrolides and amikacin remains the optimal choice, although it depends on the location and severity of the infection; however, resistance genes have been identified in some subspecies that limit antibiotic efficacy. We present the case of a patient with cutaneous coinfection by Mycobacterium abscessus and Mycobacterium tuberculosis, who presented exogenous Cushing syndrome, a predisposing factor for these infections. In addition, hydatidosis and pulmonary aspergillosis were identified. The patient's anti-tuberculosis treatment was adjusted to manage both mycobacteria, resulting in a favorable evolution.

Aspergillosis is an opportunistic fungal infection that occurs mainly in immunosuppressed patients and its main source of transmission is the spores present in the air of operating rooms and intensive care units(AU)

Diagnóstico de un caso inusual de micetoma por Aspergillus / Diagnosis of an unusual case of Mycetoma due to Aspergillus

Introducción: Las aspergilosis comprenden un amplio y heterogéneo grupo de enfermedades oportunistas causadas por hongos del género Aspergillus, considerados como una causa inusual de infección. Es la causa más frecuente de muerte por neumonía infecciosa e infección diseminada o respiratoria oportunista, en pacientes inmunocomprometidos. Objetivos: Describir las características clínicas de un caso inusual de aspergilosis pulmonar. Caso clínico: Paciente de 56 años de edad con antecedentes personales de hepatopatía alcohólica, ingresado por episodios de expectoración con sangre y tos seca. Se realizaron estudios de laboratorio, imagenológicos y anatomopatológicos que condujeron al diagnóstico de micetoma por Aspergillus fumigatus, lo cual posibilitó indicar el tratamiento adecuado y realizar el seguimiento clínico. Conclusiones: La infección por Aspergillus fumigatus debe ser considerada por el médico de cabecera, debido a que su reporte constituye una herramienta para que pueda establecer una terapéutica temprana y adecuada, dada sus implicaciones pronósticas, su morbilidad y mortalidad en pacientes inmunodeprimidos(AU)

Introduction: Aspergillosis comprises a wide and heterogeneous group of opportunistic diseases caused by fungi of the Aspergillus genus, considered as an unusual cause of infection. It is the most frequent cause of death from infectious pneumonia and disseminated or opportunistic respiratory infection in immunocompromised patients. Objectives: Describe the clinical characteristics of an unusual case of pulmonary aspergillosis. Case report: 56-year-old patient with a personal history of alcoholic liver disease, admitted due to episodes of expectoration with blood and dry cough. Laboratory, imaging, and pathological studies were conducted that led to the diagnosis of mytoma by Aspergillus fumigatus, which made it possible to indicate the appropriate treatment and perform clinical follow-up. Conclusions: Aspergillus fumigatus infection should be considered by the attending physician, because his report constitutes a tool for him to establish an early and adequate therapy, given its prognostic implications and for its morbidity and mortality in immunocompromised patients(AU)

Secuestro pulmonar intralobar y aspergilosis pulmonar: reporte de un caso / Intralobar pulmonary sequestration and pulmonary aspergilosis: a case report

El secuestro pulmonar es un tipo de malformación congénita pulmonar poco frecuente, con presentación clínica variable y de usual diagnóstico durante la infancia. Puede coexistir con otras patologías pulmonares, principalmente de tipo infecciosas y su manejo definitivo es mediante un procedimiento quirúrgico. Se presenta el caso de una paciente adulta con secuestro pulmonar, asociado a una infección fúngica, manejada con cirugía mínimamente invasiva

Pulmonary sequestration is a rare type of congenital pulmonary malformation, with variable clinical presentation and usually diagnosed during childhood. It can coexist with other pulmonary pathologies, mainly infectious, and its definitive management is through a surgical procedure. We present the case of an adult patient with pulmonary sequestration associated with a fungal infection, managed with minimally invasive surgery

Aspergiloma pulmonar en paciente con síndrome de sobreposición: Reporte de caso / Pulmonary aspergiloma in patient with overposition syndrome: Case ́s report / Aspergiloma pulmonar em paciente com síndrome de sobreposição: Relato de caso

Introducción. La infección por Aspergillus spp. representa un reto diagnóstico y terapéutico para el clínico, puesto que existe un número aproximado de 180 especies. El pulmón es el principal órgano afectado por el Aspergillus debido a la alta capacidad esporulativa de este hongo y a que sus conidias son lo suficientemente pequeñas para poder alcanzar el alveolo. Caso. Mujer de 41 años de edad con antecedente de lupus eritematoso sistémico, ingresó con un cuadro de disfagia, en el cual se confirmó la presencia de síndrome de sobreposición mediante perfil inmunológico. Posteriormente, mediante estudio imagenológico, realizado por tener tos y disnea, se encontró la presencia de una masa ovoidea en hemitórax derecho y al realizar una fibrobroncoscopia se evidenció que dicha lesión era compatible con un aspergiloma, por lo que se dio manejo antifún-gico con una evolución clínica adecuada.Conclusión. El aspergiloma se presenta como una masa voluminosa constituida por filamentos mi-celiales, la cual se puede confundir con múltiples patologías principalmente de tipo tumoral, por lo que es necesario realizar biopsia de la misma

Introduction. For clinicians, Aspergillus spp. infection represents a diagnostic and therapeutic cha-llenge, since there are around of 180 species. Lung is the main affected organ by Aspergillus infection due to the high sporulative capacity of this fungus, and because its conidia are small, enough to reach the alveolus. Case. A 41-years-old patient with a history of systemic lupus erythematosus, was admitted with dysphagia, and an immunological pool confirmed the presence of an overlap syndrome. Later, due to symptoms of cough and dyspnea, an ovoid mass was found by imaging and fibrobronchoscopy, which showed that this lesion was compatible with aspergilloma, so antifungal therapy was given with an adequate clinical progression. Conclusions. Aspergilloma is a voluminous mass constituted by mycelial filaments, which can be confused with multiple pathologies, mainly of the tumor type, which is why it is necessary to perform a biopsy of it.

Introdução. As infecções causadas pelo fungo Aspergillus spp. representam um desafio diagnóstico e terapêutico para o clínico, uma vez que existe um número aproximado de 180 espécies. O pulmão é o principal órgão afetado por Aspergillus devido à alta capacidade esporulativa deste fungo, pois seus conídios são pequenos o suficiente para atingir o alvéolo.Caso. Mulher de 41 anos com história de lúpus eritematoso sistêmico, foi admitida com disfagia, a presença da síndrome de sobreposição foi confirmada pelo perfil imunológico. Posteriormente, por meio de um estudo de imagem, realizado devido à tosse e dispnéia, foi encontrada presença de massa ovóide no hemitórax direito e, ao realizar uma fibrobroncoscopia, foi demonstrado que a lesão era compatível com um aspergiloma, de modo que o manejo antifúngico foi dado com uma evolução clínica adequada.Conclusão. O aspergiloma é apresentado como uma massa volumosa constituída por filamentos mi-celiais, que podem ser confundidos com múltiples patologias principalmente do tipo tumoral, sendo necessária a realização de uma biópsia do mesmo

Enfermedad granulomatosa crónica: infecciones múltiples como forma de presentación. Caso clínico pediátrico / Chronic granulomatous disease: multiple infections as clinical presentation. Pediatric case report

La enfermedad granulomatosa crónica es una inmunodeficiencia primaria infrecuente, debida a un defecto en la actividad microbicida de los fagocitos, originada por mutaciones en los genes que codifican alguna de las subunidades del complejo enzimático nicotinamida adenina dinucleótido fosfato oxidasa. La incidencia estimada es 1 en 250 000 recién nacidos vivos. Puede presentarse desde la infancia hasta la adultez, por lo general, en menores de 2 años. Las infecciones bacterianas y fúngicas, en conjunto con las lesiones granulomatosas, son las manifestaciones más habituales de la enfermedad. Los microorganismos aislados más frecuentemente son Aspergillus spp., Staphylococcus aureus, Serratia marcescens, Nocardia spp. Se reporta el caso clínico de un varón de 1 año de vida en el que se diagnosticó enfermedad granulomatosa crónica a partir de infecciones múltiples que ocurrieron simultáneamente: aspergilosis pulmonar invasiva, osteomielitis por Serratia marcescens y granuloma cervical por Enterobacter cloacae.

Chronic granulomatous disease is an uncommon primary immunodeficiency due to a defect of the killing activity of phagocytes, caused by mutations in any of the genes encoding subunits of the superoxide-generating phagocyte NADPH oxidase system. The incidence is 1 in 250 000 live births. It can occur from infancy to adulthood, usually in children under 2 years. Bacterial and fungal infections in association with granuloma lesions are the most common manifestations of the disease. Aspergillus species, Staphylococcus aureus, Serratia marcescens, Nocardia species are the most common microorganisms isolated. We describe here a case of a 1-year-old boy with chronic granulomatous disease and invasive pulmonary aspergillosis, Serratia marcescens osteomyelitis and Enterobacter cloacae cervical granuloma.

Coexistencia de Aspergilosis e Hidatidosis Pulmonar. Reporte de un caso / Coexistence of Pulmonary Aspergillosis and Hydatidosis. Case report

RESUMEN La hidatidosis es una zoonosis causada por el parásito Echinococcus granulosus. Perú es una zona endémica para esta infección, presentamos el caso de una mujer de 33 años, procedente de la región de Ica; que durante la gestación se le diagnosticó hidatidosis hepática y pulmonar y posterior al término de la gestación fue referida con tubo de drenaje torácico, disnea y dolor torácico en hemitórax derecho, de curso progresivo e imagen tomográfica de tórax que mostró quiste pulmonar basal posterior derecho. Los exámenes serológicos fueron positivos, la paciente fue sometida a resección quirúrgica con resultado histopatológico de quiste hidatídico pulmonar complicado no viable y estructura micótica consistente con aspergiloma. La coexistencia de estas dos entidades es rara y pueden ser amenazas potenciales para los pacientes. El diagnóstico y tratamiento tempranos son vitales para prevenir posibles complicaciones como la hemoptisis masiva o incluso enfermedad invasiva.

ABSTRACT Hydatidosis is a zoonosis caused by the parasite Echinococcus granulosus and Peru is an endemic zone for this infection. We present the case of a 33-year old woman from the region of Ica who, during gestation, was diagnosed with liver and pulmonary hydatidosis. After gestation was terminated, she was referred with thoracic drainage tube, dyspnea, and thoracic pain in right hemithorax, with progressive course and tomographic image of thorax showing right posterior basal pulmonary cyst. The serological analysis was positive, the patient underwent surgical resection with histopathologic result as complex non-viable pulmonary hydatidic cyst and mycotic structure consistent with aspergilloma. The coexistence of these two diseases is rare and can mean potential threats for patients. The early diagnosis and treatment are vital to prevent possible complications such as massive hemoptysis or even invasive disease.

Aspergillosis pulmonar / Pulmonary aspergillosis

RESUMEN Se presenta a una paciente de 50 años de edad, atendida durante 2 años por Consulta de Neumología, en la ciudad de Matanzas. Presentaba bronquitis crónica con tratamiento para la misma, hace 3 meses ingresa por Servicio de Medicina Interna por una neumonía de lenta resolución, asociada un síndrome general. Durante el ingreso se manejan varias posibilidades diagnósticas como: posible tuberculosis pulmonar, neoplasia de pulmón o neumonía a gérmenes atípicos. Se confirmó diagnóstico de aspergilosis pulmonar mediante lavado bronquial por broncoscopio. Se aplicó tratamiento con antifúngicos sistémicos y se logró mejoría clínica y radiológica. En esta paciente no existían evidencias de inmunosupresión (AU).

ABSTRACT We present a female patient aged 50 years, attended for two years in the Pulmonology consultation, in the city of Matanzas. She suffered chronic bronchitis with treatment; three months ago she was admitted in the Internal Medicine Service due to a low resolution pneumonia associated to a general syndrome. During her staying in the hospital several diagnostic possibilities were managed: possible pulmonary tuberculosis, lung neoplasia or pneumonia to atypical germs. The diagnosis of pulmonary aspergillosis was confirmed through bronchial lavage `per bronchoscope. no existían evidencias de inmunosupresión. The pronosis is Lung Aspergilosis due to a bronchial washing for bronchoscopy and the treatment begins with systemic antifúngicos, achieving clinical and radiological improvement. There is no evidence of inmunosupression in the patient (AU).

Surgery for Pulmonary Fungal Infections Complicating Hematological Malignancies

BACKGROUND: The complication rate of fungal disease is higher among patients with hematological malignancies. We investigated the clinicobacteriological outcomes of resected pulmonary fungal infections complicating hematological malignancies. METHODS: Between 2001 and 2017, 21 patients with pulmonary fungal infections complicating hematological malignancies underwent resection, and their clinical records and survival were retrospectively reviewed. RESULTS: The median age of the patients was 47 years, and 13 were male. The histological diagnoses were pulmonary aspergillosis (19 cases), mucormycosis (1 case), and cryptococcosis (1 case). The indications for surgery were resistance to antifungal therapy and the necessity of surgery before hematopoietic stem cell transplantation in 13 and 8 cases, respectively. The diagnoses of the hematological malignancies were acute myelogenous leukemia (10 cases), acute lymphocytic leukemia (5 cases), myelodysplastic syndrome (3 cases), and chronic myelogenous leukemia, malignant lymphoma, and extramedullary plasmacytoma (1 case each). The surgical procedures were partial resection (11 cases), segmentectomy (5 cases), lobectomy (4 cases), and cavernostomy (1 case). The size of the lesions was 0.9–8.5 cm. Fourteen cases had cavitation. There were no surgical-related deaths or fungal progression. CONCLUSION: Pulmonary fungal infections are resistant to treatments for hematological malignancies. Since the treatment of the underlying disease is extended and these infections often recur and are exacerbated, surgery should be considered when possible.

Conjunction of a Fungus Ball and a Pulmonary Tumourlet in a Bronchiectatic Cavity

Herein, we describe the case of a 67-year-old female patient who presented with cough and haemoptysis. Chest computed tomography revealed destruction of the left lower lobe and multiple fungus balls in a bronchiectatic cavity. A left lower lobectomy was performed via thoracotomy. Histopathological examination of the lung showed a concomitant aspergilloma and multiple tumourlets in the large bronchiectatic cavity. Pulmonary intracavitary aspergilloma and concomitant tumourlets are quite rare. Our report presents this interesting case that manifested with haemoptysis.
