LTBI was independently associated with AMI. Our results suggest a potentially important role of LTBI in CVD.

Con el objetivo de evaluar las tendencias en el uso de fármacos en pacientes con la COVID-19 en un hospital del Perú durante la primera ola de la pandemia se realizó un estudio retrospectivo entre abril y septiembre del 2020. Se revisaron las historias clínicas de pacientes hospitalizados por neumonía por COVID-19 en el Hospital Nacional Dos de Mayo (Lima, Perú). De un total de 3103 pacientes, se incluyeron aleatoriamente 381 historias clínicas (77,4% de sexo masculino y una mediana de edad de 44 años). Se observó un incremento del uso de cuatro fármacos (azitromicina, ivermectina, corticoides y ceftriaxona) antes de la hospitalización, así como una disminución del uso de seis fármacos (ceftriaxona, azitromicina, hidroxicloroquina, ivermectina, pulso de corticoides y anticoagulación profiláctica) y un aumento en el uso de anticoagulación plena, durante la hospitalización. Estos hallazgos sugieren que el manejo de la COVID-19 varió durante la primera ola de la pandemia, aumentando el uso de fármacos prehospitalarios y disminuyendo el uso de fármacos intrahospitalarios.

BackgroundWe previously reported increased unstimulated blood levels of interferon-gamma in persons with latent tuberculosis infection (LTBI) in the United States, suggesting enhanced immune activation in LTBI. To investigate this further in a TB-endemic setting, we assessed interferon-gamma levels in persons with and without LTBI in Peru.MethodsWe analyzed data from patients with and without a recent type 1 (spontaneous) acute myocardial infarction (AMI) who were enrolled from two public hospital networks in Lima, Peru, and underwent LTBI testing using the QuantiFERON® TB Gold In-tube (QFT) assay. Participants with a positive QFT test were defined as having LTBI, whereas participants with a negative QFT test were defined as non-LTBI. Unstimulated interferon-gamma was quantified via enzyme-linked immunosorbent assay in the QFT nil-tube, which does not contain antigens. We compared unstimulated interferon-gamma levels between LTBI and non-LTBI groups using the Wilcoxon rank sum test. We used proportional odds modeling for multivariable analysis.ResultsData from 214 participants were included in this analysis. Of those, 120 (56%) had LTBI. There were no significant differences in age, sex and comorbidities between LTBI and non-LTBI participants, except for recent AMI that was more frequent in LTBI. LTBI participants had higher unstimulated interferon-gamma levels compared to non-LTBI participants (median, interquartile range; 14 pg/mL, 6.5–52.8 vs. 6.5 pg/mL, 4.5–15; P<0.01). LTBI remained associated with higher unstimulated interferon-gamma levels after controlling for age, sex, recent AMI, history of hypertension, diabetes mellitus, dyslipidemia, end stage renal disease, malignancy, obesity, and tobacco use (adjusted odds ratio, 2.93; 95% confidence interval, 1.8–4.9). In a sensitivity analysis that excluded participants with AMI, the association between unstimulated interferon-gamma and LTBI remained present (adjusted odds ratio; 3.93; 95% confidence interval, 1.9–8.2).ConclusionsLTBI was associated with higher unstimulated interferon-gamma levels. These data suggest ongoing immune activation in LTBI.

RESUMENEl objetivo del estudio fue determinar la frecuencia y características de la dislipidemia en pacientes con VIH en terapia antirretroviral de gran actividad (TARGA) en un hospital público peruano. Se realizó un estudio transversal en pacientes que tuvieran un perfil lipídico completo luego de recibir al menos seis meses de TARGA. La dislipidemia se definió según los criterios NCEP-ATP III. Se revisaron 2975 historias clínicas, 538 (18.1%) fueron incluidas en el análisis. La frecuencia de dislipidemia fue 74.7%. Los esquemas de TARGA que incluían inhibidores de la proteasa (IP) (OR 1.22; IC95% 1,11-1,34) y la edad mayor de 40 años (OR 1.17; IC95% 1,06-1,29) mostraron asociación con dislipidemia, ajustado por carga viral, nivel de células CD4 y sexo. En conclusión, la dislipidemia fue muy frecuente en la muestra estudiada y estuvo asociada principalmente al uso de IP. Es necesario promover el control de la dislipidemia como parte de la atención integral del paciente con infección por VIH.

HIGH FREQUENCY OF DYSLIPIDEMIA IN HIV-INFECTED PATIENTS IN A PERUVIAN PUBLIC HOSPITAL ABSTRACTThe objective of the study was to determine the frequency and characteristics of dyslipidemia in patients with HIV in highly active antiretroviral therapy (HAART) in a Peruvian public hospital. A cross-sectional study was carried out in patients with complete lipid profile after receiving at least six months of HAART. Dyslipidemia was defined according to the criteria of the NCEP-ATP III. We reviewed 2 975 clinical histories, and included 538 (18.1%) in the analysis. The frequency of dyslipidemia was 74.7%. HAART regimens which include protease inhibitors (PI) (odds ratio [OR]: 1.22; confidence interval at 95% [CI 95%]: 1.11-1.33) and to be older than 40 years (OR: 1.17; CI 95%: 1.05-1.28) were associated with dyslipidemia, adjusted by viral load, CD4 lymphocyte level and gender. In conclusion, dyslipidemia was very common in our sample and was mainly associated with the use of PI. It is necessary to promote the dyslipidemia control as part of the comprehensive care of the patient with HIV.
