The impact of the COVID-19 pandemic on people living with HIV: a cross-sectional study in Caracas, Venezuela.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has disrupted multiple health services, including human immunodeficiency virus (HIV) testing, care, and treatment services, jeopardizing the achievement of the Joint United Nations Programme on HIV/AIDS 90-90-90 global target. While there are limited studies assessing the impact of the COVID-19 pandemic on people living with HIV (PLHIV) in Latin America, there are none, to our knowledge, in Venezuela. This study aims to assess the impact of the COVID-19 pandemic among PLHIV seen at the outpatient clinic of a reference hospital in Venezuela. METHODS: We conducted a cross-sectional study among PLHIV aged 18 years and over seen at the Infectious Diseases Department of the University Hospital of Caracas, Venezuela between March 2021 and February 2022. RESULTS: A total of 238 PLHIV were included in the study. The median age was 43 (IQR 31-55) years, and the majority were male (68.9%). Most patients (88.2%, n = 210) came for routine check-ups, while 28 (11.3%) were newly diagnosed. The majority of patients (96.1%) were on antiretroviral therapy (ART), but only 67.8% had a viral load test, with almost all (95.6%) being undetectable. Among those who attended regular appointments, 11.9% reported missing at least one medical consultation, and 3.3% reported an interruption in their ART refill. More than half of the patients (55.5%) had received at least one dose of the COVID-19 vaccine, while the rest expressed hesitancy to get vaccinated. Most patients with COVID-19 vaccine hesitancy were male (65.1%), younger than 44 years (57.5%), employed (47.2%), and had been diagnosed with HIV for less than one year (33%). However, no statistically significant differences were found between vaccinated patients and those with COVID-19 vaccine hesitancy. Older age was a risk factor for missing consultations, while not having an alcoholic habit was identified as a protective factor against missing consultations. CONCLUSION: This study found that the COVID-19 pandemic had a limited impact on adherence to medical consultations and interruptions in ART among PLHIV seen at the University Hospital of Caracas, Venezuela.

First wave of COVID-19 in Venezuela: Epidemiological, clinical, and paraclinical characteristics of first cases.

The coronavirus disease 2019 (COVID-19) pandemic has particularly affected countries with weakened health services in Latin America, where proper patient management could be a critical step to address the epidemic. In this study, we aimed to characterize and identify which epidemiological, clinical, and paraclinical risk factors defined COVID-19 infection from the first confirmed cases through the first epidemic wave in Venezuela. A retrospective analysis of consecutive suspected cases of COVID-19 admitted to a sentinel hospital was carried out, including 576 patient cases subsequently confirmed for severe acute respiratory syndrome coronavirus 2 infection. Of these, 162 (28.1%) patients met the definition criteria for severe/critical disease, and 414 (71.2%) were classified as mild/moderate disease. The mean age was 47 (SD 16) years, the majority of which were men (59.5%), and the most frequent comorbidity was arterial hypertension (23.3%). The most common symptoms included fever (88.7%), headache (65.6%), and dry cough (63.9%). Severe/critical disease affected mostly older males with low schooling (p < 0.001). Similarly, higher levels of glycemia, urea, aminotransferases, total bilirubin, lactate dehydrogenase, and erythrocyte sedimentation rate were observed in severe/critical disease patients compared to those with mild/moderate disease. Overall mortality was 7.6% (44/576), with 41.7% (28/68) dying in hospital. We identified risk factors related to COVID-19 infection, which could help healthcare providers take appropriate measures and prevent severe clinical outcomes. Our results suggest that the mortality registered by this disease in Venezuela during the first epidemic wave was underestimated. An increase in fatalities is expected to occur in the coming months unless measures that are more effective are implemented to mitigate the epidemic while the vaccination process is ongoing.

Amoebic liver abscess in a COVID-19 patient: a case report.

BACKGROUND: Amoebiasis is a parasitic disease caused by Entamoeba histolytica, which affects people living in low- and middle-income countries and has intestinal and extraintestinal manifestations. To date, knowledge on coronavirus disease 2019 (COVID-19) coinfection with enteric parasites is limited, and E. histolytica coinfection has not been previously described. Here we present the case of a patient with COVID-19 who, during hospitalisation, presented a clinical picture consistent with an amoebic liver abscess (ALA). CASE PRESENTATION: A 54-year-old man, admitted as a suspected case of COVID-19, presented to our hospital with dyspnoea, malaise, fever and hypoxaemia. A nasopharyngeal swab was positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by reverse-transcription polymerase chain reaction. After 7 days, he developed diarrhoea, choluria and dysentery. An abdominal ultrasound showed a lesion compatible with a liver abscess; stool examination revealed E. histolytica trophozoites, and additional serology for E. histolytica was positive. After 12 days of treatment with metronidazole, ceftazidime and nitazoxanide, the patient reported acute abdominal pain, and an ultrasound examination revealed free liquid in the abdominal cavity. An emergency exploratory laparotomy was performed, finding 3000 mL of a thick fluid described as "anchovy paste". Computed tomography scan revealed a second abscess. He ended up receiving 21 days of antibiotic treatment and was discharged with satisfactory improvement. CONCLUSION: Here we present, to the best of our knowledge, the first report of ALA and COVID-19 co-presenting. Based on their pathophysiological similarities, coinfection with SARS-CoV-2 and E. histolytica could change the patient's clinical course; however, larger studies are needed to fully understand the interaction between these pathogens.

Knowledge, attitudes, and practices related to COVID-19 among patients at Hospital Universitario de Caracas triage tent: A cross-sectional study. / Conocimientos, actitudes y prácticas relacionadas con COVID-19 en pacientes de la carpa de triaje del Hospital Universitario de Caracas: un estudio transversal

INTRODUCTION: The studies on knowledge, attitudes, and practices (KAP) regarding COVID-19 help to identify erroneous concepts and inadequate practices related to the disease. This baseline information is essential to design effective strategies and improve adherence to prevention measures. OBJECTIVE: To identify the COVID-19-related KAP in Venezuelan patients screened at the Hospital Universitario de Caracas triage tent. MATERIALS AND METHODS: We conducted a cross-sectional study among 215 patients between April 25th and May 25th, 2020, with in-person interviews using a KAP survey. RESULTS: Most surveyed patients (53.5%) were asymptomatic. Most of them, both from the symptomatic and the asymptomatic groups, had adequate knowledge about the symptoms and transmission of the disease and the majority said they were practicing quarantine, frequent handwashing, and the use of face masks in public areas. However, the daily replacement of cloth face masks was more frequent in the asymptomatic group whereas replacement every three days was more frequent in the symptomatic group. Finally, more than half of the participants admitted having been in crowded places, a common practice among the symptomatic compared to the asymptomatic patients. CONCLUSIONS: This is the first KAP study in Venezuela about COVID-19. Knowledge and practices among Venezuelans could be improved by strengthening education and training programs. This information from the early phase of the pandemic in Venezuela may contribute to the design of COVID-19 promotion and prevention strategies.

Introducción: Los estudios sobre conocimientos, actitudes y prácticas (CAP) sobre COVID-19 ayudan a identificar conceptos erróneos y prácticas inadecuadas relacionadas con la enfermedad. Esta información de referencia es fundamental para diseñar estrategias efectivas y mejorar la adherencia a las medidas de prevención. Objetivo: Identificar la CAP relacionada con COVID-19 en pacientes venezolanos cribados en la carpa de triaje del Hospital Universitario de Caracas. Materiales y métodos: Realizamos un estudio transversal entre 215 pacientes entre el 25 de abril y el 25 de mayo de 2020, con entrevistas en persona utilizando una encuesta KAP. Resultados: La mayoría de los pacientes encuestados (53,5%) se encontraban asintomáticos. La mayoría de ellos, tanto del grupo sintomático como asintomático, tenían un conocimiento adecuado sobre los síntomas y la transmisión de la enfermedad y la mayoría dijo que practicaban la cuarentena, el lavado frecuente de manos y el uso de mascarillas en las áreas públicas. Sin embargo, el reemplazo diario de mascarillas de tela fue más frecuente en el grupo asintomático, mientras que el reemplazo cada tres días fue más frecuente en el grupo sintomático. Finalmente, más de la mitad de los participantes admitieron haber estado en lugares concurridos, una práctica común entre los sintomáticos en comparación con los asintomáticos. Conclusiones: Este es el primer estudio CAP en Venezuela sobre COVID-19. El conocimiento y las prácticas entre los venezolanos podrían mejorarse fortaleciendo los programas de educación y capacitación. Esta información de la fase inicial de la pandemia en Venezuela puede contribuir al diseño de estrategias de promoción y prevención del COVID-19.

La actividad académica fue regular durante la década, cumpliendose los programas correspondientes. El número de horas empleadas en las revistas a los pacientes hospitalizados en el SEIA fue > 300/año. Seis miembros del servicio participaron en el programa del control de infecciones del HUC. Residentes y especialistas del SEIA cumplieron las funciones del infectológo en la última década;El mayor número de pacientes fue atendido de forma ambulatoria (consultas y la STA).

Hospital role of infectious diseases (ID) specialists is important. They participate in outpatient and inpatient care, hospital infection control, academic and research activities, and also pandemic and epidemic issues. This study's aim was to assess the number of activities, booth academic and im patients care, and fulfillment of ID physicians'roles at HUC during the last decade. Analysis of records for patient care and academic programs during January 1, 2000 to December 31, 2009. The number of patients clinically assessed and academic hours spent was calculated. During the decade, 110 691 patients were evaluated. There was a progessive increase of patients cared fir throughout they years. The activities distribution was as follows: 72 521 (65 %) outpatients (35 % HIV infected patients y % non HIV); 18 682 inpatients assessed following HUC policy on antibiotic control (17 %); 12 792 (12 %) courses of treatment administered at the outpatient treatment clinic (OTC); 3 764 (3 %) discharged patients fron SEIA y 2 932 people evaluated because of biologic risk exposition. Academic activities were fulfilled according to the fellowship program. Physicians dedicated more than 300 hour/year for inpatient rounds at SEIA. Six specialist form the ID Service also Were Members of HUC Infection Control Committee. Physicians at SEIA have accomplished the role of ID doctors during the last decade; most patients were evaluated outpatients and at OTC.

Estudio clínico-epidemiológico de la criptococosis en Venezuela: años 1994-2003 / Clinical-epidemological study of cryptococcosis in Venezuela: 1994-2003

La criptococosis es una enfermedad oportunista de distribución mundial. Frecuentemente es una infección definitoria de SIDA. El tratamiento antirretroviral ha disminuido su frecuencia. El impacto de esta entidad en Venezuela es desconocido. El objetivo de este trabajo es describir las características más relevantes de la criptococosis en nuestro país. Se revisaron 110 historias clínicas de pacientes hospitalizados con el diagnostico de criptococosis, entre 1994 y 2003, en 6 hospitales. Los datos recolectados incluyeron: características demográficas, clínicas, diagnósticas, terapéuticas y la evolución de los pacientes. Para el análisis se utilizaron los programas SPSS 10.0 y EpiInfo 6.04 (2001). Dentro de los 110 pacientes evaluados se incluyeron 17 protocolos de autopsia. Uno solo de los pacientes tenia 8 años de edad, el resto era mayor de 15 años. 91 eran del sexo masculino y 19 femenino. 91 (82,73 por ciento) tenían SIDA y 19 (17,27 por ciento) eran VIH negativo. En los pacientes con SIDA el valor promedio de CD4+ fue < 200 cel/mm³ y la carga viral era > 30000 copias/mL; 52 (57,14 por ciento) de los casos no tenían otra infección oportunista y 39 (42,86 por ciento) tenían otras condiciones asociadas, tales como tuberculosis (30,97 por ciento), neumocistosis (28,21 por ciento), y toxoplasmosis (20,51 por ciento). En los pacientes VIH negativo, el uso de esteroides (25 por ciento) fue el factor de riesgo predominante. Dos pacientes eran embarazadas. En 107 (57,27 por ciento) se encontró infección del SNC. 12 (13,19 por ciento) de los pacientes con SIDA tenían alteración de pares craneales. Se encontró afectación pulmonar en 4 (3,77 por ciento) pacientes, 1 de ellos con SIDA. La criptococosis fue la enfermedad definitoria de SIDA en el 61,54 por ciento de los casos. 33 (30 por ciento) de los pacientes fallecieron. En la mayoría de los pacientes la criptococosis se asoció a SIDA. A pesar de la eficacia del tratamiento antirretrovial, esta micosis es todavia ...

Cryptococcosis is an opportunistic disease of worldwide distribution. It is frequently an AIDS-defining infection. Antiretroviral treatment has reduced its occurrence. In Venezuela, the impact of this disease is unknown. The aim of this study is to describe the most relevant features of cryptococcosis in our country. 110 clinical records with a diagnosis of cryptococcosis hospitalized between 1994 and 2003 in 6 Venezuelan hospitals were analyzed. Data collected included demographic, clinical, diagnostic, therapeutic and outcome information. SPSS 10.0 software and EpiInfo 6, version 6.04 (2001) were used. 110 patients with cryptococcosis were enrolled, including 17 autopsy protocols. One was 8 years old, the rest were over 15. Nineteen were female and 91 male; 91 (82.73 percent) had AIDS, 19 (17.27 percent) were HIV negative. Among the AIDS patients, average CD4+ count was < 200 cel/mm3 and viral load was > 30000 copies/ml; 52 (57.14 percent) did not have other opportunistic infections or AIDS-related disease, and 39 (42.86 percent) had other associated conditions, such as tuberculosis (30.97 percent), PCP (28.21 percent) and toxoplasmosis (20.51 percent). In HIV negative patients, use of steroids (25 percent) was the predominant risk factor. Two patients were pregnant. 107 (57.27 percent) presented CNS infection; 12 (13.19 percent) with AIDS had cranial nerve alterations. Pulmonary disease was found in 4 (3.77 percent), of which one had AIDS. Cryptococcosis was an AIDS-defining infection in 61.54 percent of cases; 33 (30 percent) of the patients died. In most of the patients, cryptococcosis was associated with AIDS. In spite of the efficacy of antiretroviral treatment, this mycosis is still significant in Venezuela, perhaps due to late HIV infection diagnosis

Osteomielitis Crónica en el Hospital Universitario de Caracas / Chronic Osteomyelitis at the University Hospital in Caracas

La osteomielitis crónica (OMC) persiste como un problema de difícil solución, con múltiples recurrencias, limitaciones diagnósticas y terapéuticas que generan complicaciones discapacitantes y numerosas hospitalizaciones. Es consecuencia de un diagnóstico tardío o tratamiento ineficaz, que hacen crucial la adecuada utilización de los métodos diagnósticos y de un tratamiento óptimo. Se realizó un estudio descriptivo de los casos de OMC en el Hospital Universitario de Caracas (HUC). Se revisaron las historias del HUC entre enero 1995 y enero 2001, obteniéndose 207 casos, para estudiar las características de la enfermedad con respecto a: edad, sexo, hueso mayormente afectado, factores de riesgo o enfermedades subyacentes, métodos diagnósticos utilizados, microorganismos aislados y tipo de tratamiento. Las características estudiadas fueron similares a lo descrito en la literatura. La radiología fue el estudio más utilizado (84,06%), sin embargo se apreció una subutilización de los métodos diagnósticos disponibles. Se realizó tratamiento combinado médico-quirúrgico (antibioticoterapia y limpieza quirúrgica) en 76,81% de los pacientes, se tomaron muestras óseas para cultivos en 53,83% de los pacientes intervenidos, se apreció un alto porcentaje de recaídas (35,22%) y amputaciones (47,77%), lo que refleja un manejo no óptimo de la OMC, que genera una morbilidad significativa que afecta la calidad de vida e incrementa los costos hospitalarios.

Chronic osteomyelitis (COM) persists as a difficult to solve problem, with multiple recurrences, diagnostic and therapeutic limitations that generate disabling complications, and numerous hospitalizations. It is consequence of a retarded diagnosis or ineffective treatment, which turn make an adequate use of diagnostic methods and optimal treatment crucial. A descriptive study of COM cases seen at the University Hospital in Caracas between January 1995 and January 2001 included a total of 207 cases. The study included the characteristics of the disease regarding age, sex, most compromised bone, risk factors or underlying diseases, diagnostic methods used, microorganisms isolated and type of treatment. The characteristics studied were similar to those described in the literature. Radiology was the most used examination (84.06%); nevertheless, there was a sub utilization of diagnostic methods available. A combined medical-surgical treatment (antibiotics and surgical cleaning) was used in 76.81% of the patients; bone samples for culture were taken from 53.83% of the patients treated; and there was a high percentage of relapses (35.22%) and amputations (47.77%), which reflects a non optimal management of COM, that generates a significant morbidity that affects life quality and increases hospital costs.

Candida albicans osteomyelitis: case report and literature review.

OBJECTIVE: Osteomyelitis due to Candida species is an unusual but recognized entity. However, with the increasing occurrence of factors predisposing to candidemia and invasive candidiasis, candidal osteomyelitis is being diagnosed more frequently. An unusual case of Candida albicans osteomyelitis is reported here, along with a review of the published literature on previously reported cases of this disease. METHODS: Report of the case and literature review. RESULTS: In this case, Candida albicans was isolated from the talus; however, the diagnosis was made after several cultures were performed. Only one other case of Candida osteomyelitis located in foot bones was found in the review. CONCLUSIONS: It is thought that this is the first case reported in Venezuela, and only the second in international literature.
