Identificación de dislipidemias en niños VIH positivos con tratamiento antirretroviral de gran actividad en el Hospital Rebagliati. Periodo 2010-2015

Desde la introducción del tratamiento antirretroviral de gran actividad (TARGA), la infección por el virus de la inmunodeficiencia humana (VIH) en niños es una enfermedad crónica con excelente pronóstico a largo plazo, con una reducción significativa de las tasas de hospitalización por enfermedades oportunistas y de la mortalidad. Sin embargo la mejoría de la calidad de vida se ha visto limitada por los efectos adversos al TARGA y una de ellos es la alteración del metabolismo lipídico, cuya valoración se hace a través de análisis seriados. Existen muy pocos estudios en el país que evalúan el efecto de TARGA en el metabolismo lipídico de los niños con VIH, por lo cual se ha realiza este trabajo. Realiza un estudio observacional, descriptivo, retrospectivo, longitudinal. Se incluyeron 35 niños menores de 16 años. Existió un 66% de dislipidemias, con incremento significativo de los triglicéridos y VLDL-Colesterol a los 6 meses de tratamiento y de colesterol y LDL-Colesterol a los 12 meses de tratamiento. Los niños bajo el esquema que contenían inhibidores de proteasa tuvieron alteraciones del metabolismo lipídico a los 6 meses de tratamiento, en triglicéridos y VLDL-Colesterol. Concluye que las dislipidemias en la población estudiada fueron del 66%. Los inhibidores de la proteasa fueron asociados a incremento de los niveles de triglicéridos y VLDL-Colesterol a los 6 meses de tratamiento.Tesi

Seronegative disseminated Bartonella spp. infection in an immunocompromised patient

An 11 year old, hispanic girl with a history of B-cell acute lymphoblastic leukemia was admitted to the hospital for symptoms compatible with Bartonella henselae infection. The first molecularly diagnosed case of disseminated Bartonella henselae infection was reported in an immunocompromised patient in Lima, Peru. The analysis was confirmed by Polymerase Chain Reaction and automated sequencing of a liver biopsy sample, even though the serologic tests were negative. In conclusion, Bartonella spp. infection should have a particular diagnostic consideration in immunocompromised patients with fever of unknown origin and further investigation regarding the patient's past exposures with cats should also be elicited

Clinical phenotypes of multisystem inflammatory syndrome in children (MIS-C) associated with COVID-19

The multisystem inflammatory syndrome in children associated with COVID-19 (MIS-C) is infre-quent but potentially lethal. There are few reports of this disease and its phenotypes in Latin America. Objective: To describe the characteristics of the clinical phenotypes of MIS-C in hospitalized patients in Lima, Peru. Patients and Method: A descriptive and retrospective study in patients under 14 years old with a diagnosis of MIS-C at the Hospital Nacional Edgardo Rebagliati Martins (Lima, Perú), from April 2020 to August 2021. Clinical-demographic and microbiological variables were recorded. According to these, patients with MIS-C were classified into the shock phenotype, Kawasaki disease (KD) without shock, and the fever and inflammation phenotype, analyzing their clinical outcomes. Results: 58 patients were analyzed. 32 (55.2%) presented the shock phenotype, 15 (25.8%) Kawasaki disease (KD) phenotype without shock, and 11 (19%) fever and inflammation phenotype. In the shock phenotype, 17 had KD. The mean age was 7 ± 3.5 years and 67.2% were males. Gastrointes-tinal and mucocutaneous manifestations predominated in all phenotypes. The mortality was 3.5%. The frequency of coronary aneurysms was 10.2%. Most patients received immunomodulatory and antiplatelet treatment. Patients with shock phenotype showed greater involvement in inflammatory markers, hematological dysfunction, and myocardial injury, with a higher frequency of respiratory failure and invasive mechanical ventilation. Conclusions: In our case series, patients with shock phenotype were the most frequent and had worse clinical outcomes. Active surveillance of clinical phenotypes is needed to make an early diagnosis and management to improve the prognosis in these patients.Revisión por pare

Identfication of viral and bacterial etiologic agents of the pertussis-like syndrome in children under 5 years old hospitalized

Background: Acute respiratory infections (ARIs) represent an important cause of morbidity and mortality in children, remaining a major public health concern, especially affecting children under 5 years old from low-income countries. Unfortunately, information regarding their epidemiology is still limited in Peru. Methods: A secondary data analysis was performed from a previous cross-sectional study conducted in children with a probable diagnosis of Pertussis from January 2010 to July 2012. All samples were analyzed via Polymerase Chain Reaction (PCR) for the following etiologies: Influenza-A, Influenza-B, RSV-A, RSV-B, Adenovirus, Parainfluenza 1 virus, Parainfluenza 2 virus, Parainfluenza 3 virus, Mycoplasma pneumoniae and Chlamydia pneumoniae. Results: A total of 288 patients were included. The most common pathogen isolated was Adenovirus (49%), followed by Bordetella pertussis (41%) from our previous investigation, the most prevelant microorganisms were Mycoplasma pneumonia (26%) and Influenza-B (19.8%). Coinfections were reported in 58% of samples and the most common association was found between B. pertussis and Adenovirus (12.2%). Conclusions: There was a high prevalence of Adenovirus, Mycoplasma pneumoniae and other etiologies in patients with a probable diagnosis of pertussis. Despite the presence of persistent cough lasting at least two weeks and other clinical characteristics highly suspicious of pertussis, secondary etiologies should be considered in children under 5 years-old in order to give a proper treatment.Revisión por pare

Clinical Presentation and Outcomes of Kawasaki Disease in Children from Latin America: A Multicenter Observational Study from the REKAMLATINA Network

Objetivos: Describir la presentación clínica, el manejo y los resultados de la enfermedad de Kawasaki (EK) en Latinoamérica y evaluar los indicadores pronósticos tempranos de aneurisma de la arteria coronaria (AAC). Diseño del estudio: Se realizó un estudio observacional basado en el registro de la EK en 64 centros pediátricos participantes de 19 países latinoamericanos de forma retrospectiva entre el 1 de enero de 2009 y el 31 de diciembre de 2013, y de forma prospectiva desde el 1 de junio de 2014 hasta el 31 de mayo de 2017. Se recopilaron datos demográficos, clínicos y de laboratorio iniciales. Se utilizó una regresión logística que incorporaba factores clínicos y la puntuación z máxima de la arteria coronaria en la presentación inicial (entre 10 días antes y 5 días después de la inmunoglobulina intravenosa [IGIV]) para desarrollar un modelo pronóstico de AAC durante el seguimiento (>5 días después de la IGIV). Resultados: De 1853 pacientes con EK, el ingreso tardío (>10 días tras el inicio de la fiebre) se produjo en el 16%, el 25% tuvo EK incompleta y el 11% fue resistente a la IGIV. Entre los 671 sujetos con puntuación z de la arteria coronaria notificada durante el seguimiento (mediana: 79 días; IQR: 36, 186), el 21% presentaba AAC, incluido un 4% con aneurismas gigantes. Un modelo pronóstico simple que utilizaba sólo una puntuación z de la arteria coronaria máxima ≥2,5 en la presentación inicial fue óptimo para predecir la AAC durante el seguimiento (área bajo la curva: 0,84; IC del 95%: 0,80, 0,88). Conclusiones: De nuestra población latinoamericana, la puntuación z de la arteria coronaria ≥2,5 en la presentación inicial fue el factor pronóstico más importante que precedió a la AAC durante el seguimiento. Estos resultados resaltan la importancia de la ecocardiografía temprana durante la presentación inicial de la EK. © 2023 Los autoresObjectives: To describe the clinical presentation, management, and outcomes of Kawasaki disease (KD) in Latin America and to evaluate early prognostic indicators of coronary artery aneurysm (CAA). Study design: An observational KD registry-based study was conducted in 64 participating pediatric centers across 19 Latin American countries retrospectively between January 1, 2009, and December 31, 2013, and prospectively from June 1, 2014, to May 31, 2017. Demographic and initial clinical and laboratory data were collected. Logistic regression incorporating clinical factors and maximum coronary artery z-score at initial presentation (between 10 days before and 5 days after intravenous immunoglobulin [IVIG]) was used to develop a prognostic model for CAA during follow-up (>5 days after IVIG). Results: Of 1853 patients with KD, delayed admission (>10 days after fever onset) occurred in 16%, 25% had incomplete KD, and 11% were resistant to IVIG. Among 671 subjects with reported coronary artery z-score during follow-up (median: 79 days; IQR: 36, 186), 21% had CAA, including 4% with giant aneurysms. A simple prognostic model utilizing only a maximum coronary artery z-score ≥2.5 at initial presentation was optimal to predict CAA during follow-up (area under the curve: 0.84; 95% CI: 0.80, 0.88). Conclusion: From our Latin American population, coronary artery z-score ≥2.5 at initial presentation was the most important prognostic factor preceding CAA during follow-up. These results highlight the importance of early echocardiography during the initial presentation of KD. © 2023 The Author(s

Detection of Bordetella pertussis using a PCR test in infants younger 3 than one year old hospitalized with whooping cough in five 4 Peruvian hospitals

Objectives To report the incidence, epidemiology, and clinical features of Bordetella pertussis in Peruvian infants under 1 year old. Patients and methods A prospective cross-sectional study was conducted in five hospitals in Peru from January 2010 to July 2012. A total of 392 infants under 1 year old were admitted with a clinical diagnosis of whooping cough and tested for B. pertussis by PCR. Results The pertussis toxin and IS481 genes were detected in 39.54% (155/392) of the cases. Infants aged less than 3 months were the most affected, with a prevalence of 73.55% (114/155). The most common household contact was the mother, identified in 20% (31/155) of cases. Paroxysm of coughing (89.03%, 138/155), cyanosis (68.39%, 106/155), respiratory distress (67.09%, 104/155), and breastfeeding difficulties (39.35%, 61/155) were the most frequent symptoms reported. Conclusion An increase in pertussis cases has been reported in recent years in Peru, despite national immunization efforts. Surveillance with PCR for B. pertussis is essential, especially in infants less than 1 year old, in whom a higher rate of disease-related complications and higher mortality have been reported
