Active cancer as the main predictor of mortality for COVID-19 in oncology patients in a specialized center.

Introduction: The role of the type, stage and status of cancer in the outcome of COVID-19 remains unclear. Moreover, the characteristic pathological changes of severe COVID-19 reveled by laboratory and radiological findings are similar to those due to the development of cancer itself and antineoplastic therapies. Objective: To identify potential predictors of mortality of COVID-19 in cancer patients. Materials and methods: A retrospective and cross-sectional study was carried out in patients with clinical suspicion of COVID-19 who were confirmed for COVID-19 diagnosis by RT-PCR testing at the National Institute of Neoplastic Diseases between April and December 2020. Demographic, clinical, laboratory and radiological data were analyzed. Statistical analyses included area under the curve and univariate and multivariate logistic regression analyses. Results: A total of 226 patients had clinical suspicion of COVID-19, the diagnosis was confirmed in 177 (78.3%), and 70/177 (39.5%) died. Age, active cancer, leukocyte count ≥12.8 × 109/L, urea ≥7.4 mmol/L, ferritin ≥1,640, lactate ≥2.0 mmol/L, and lung involvement ≥35% were found to be independent predictors of COVID-19 mortality. Conclusion: Active cancer represents the main prognosis factor of death, while the role of cancer stage and type is unclear. Chest CT is a useful tool in the prognosis of death from COVID-19 in cancer patients. It is a challenge to establish the prognostic utility of laboratory markers as their altered values it could have either oncological or pandemic origins.

Clinical-epidemiological and treatment characteristics of children with COVID-19 in a tertiary referral center in Peru / Características clínicas de niños con COVID-19 admitidos en un centro terciario de referencia en el Perú

Introduction: The COVID-19 pandemic has a great impact on children's health. This study describes the characteristics of hospitalized children at the San Borja National Children's Health Institute in Perú. Methods: This was a retrospective study of patients with a confirmed diagnosis of COVID-19 from March to July 2020. Demographic, clinical, laboratory, radiological, and treatment information were collected. Data analysis included descriptive statistics and bivariate analysis to determine differences between patients in general wards and the intensive care unit (ICU). Results: We included 91 patients, 33 being females (36.3%). The most affected age group was children > 2 years of age (63 cases) with a median age of 6 years (IQR 3-10), and 61.5% were from Lima. The previous contact was determined in 30.8% of cases. A positive SARS CoV-2 PCR result was obtained in 50.6%. The presence of comorbidity was 53.8%. The most frequent symptoms were: fever (39.6%), general malaise (23.1%), cough (19.8%), and respiratory distress (14.3%). The presence of multisystem inflammatory syndrome in children (MIS-C) was confirmed in 6 patients. Antibiotics were administered in 76.9%. The most frequent radiological pattern was bilateral interstitial infiltrates (57.7%). Mortality was higher in patients in the ICU than in the hospitalization ward (27.3% vs. 4.3%, respectively; p = 0.020) Conclusions: COVID-19 in children presents mild and moderate clinical manifestations. The presence of comorbidity is an important factor for hospitalization, and mortality is high upon admission to critical care units.

Primary renal aspergillosis in a newborn: a case report and review of the literature on children.

BACKGROUND: Primary renal aspergillosis is uncommon and mainly affects people with immune system impairment and/or genitourinary disease. CASE: We report the case of a male newborn with Down syndrome and congenital heart disease, who underwent surgery for anorectal malformation and presented persistent fever and impaired kidney function secondary to kidney abscesses due to Aspergillus. The patient responded favorably to antifungal treatment and percutaneous drainage but died following heart surgery. CONCLUSIONS: To the best of our knowledge, only seven cases of renal aspergillosis have been reported in children worldwide, this being the second in a newborn. Aspergillus species must be considered among the fungal etiological agents of genitourinary tract infections in order to establish adequate antifungal treatment to achieve therapeutic success against filamentous fungi.

Cystic echinococcosis (CE) in children is a public health problem. To describe the clinical and epidemiological profile of CE, we reviewed the records of 55 children admitted to our institution with a confirmed diagnosis of CE between 2017-2019, analyzing demographic data, clinical manifestations, and treatment. Of the population, 61.8% (34/55) were male. The mean age was 9.25 years (SD: 2.79); 16.4% had previous CE diagnosis, and 50.9% had contact with dogs. The median time of illness was 2 months. Of the patients, 65.5% had hepatic involvement, 56.4% had pulmonary involvement, and 21.8% had both hepatic and pulmonary involvement. The most frequent symptoms were abdominal pain (80.6%) and cough (80.6%). Surgical treatment was performed in 87.5% of patients with hepatic CE, in 100% of those with pulmonary CE and in 100% of those with hepatic and pulmonary CE. Albendazole was prescribed in 100% of hepatic cases, in 73.7% of pulmonary cases, and in 75% of those with both conditions. Mortality was not reported.

Clinicopathological Features and Mortality in Patients With Kaposi Sarcoma and HIV: A Retrospective Analysis of a Thirty-Year Study From a Peruvian Oncologic Center.

PURPOSE: Kaposi's sarcoma (KS) is a multifocal angioproliferative disease. In Peru, the implementation of the highly active antiretroviral treatment (HAART) program was in 2005, the model for treating patients with HIV-positive KS shifted to a potential cure. In this study, we aim to compare clinicopathological characteristics and prognostic factors associated with outcomes in patients with HIV-positive KS. METHODS: We developed a retrospective cohort study that includes patients with HIV/AIDS and KS seen in the Instituto Nacional de Enfermedades Neoplasicas between 1987 and 2017. Patients were divided into two groups according to the implementation of HAART in our country: the non-HAART group and those treated with HAART after 2005. Multivariate analysis for overall survival (OS) was performed with the Cox proportional hazard regression model. RESULTS: There was a greater visceral compromise and more extensive oral cavity involvement in the non-HAART group (60% 31.7%, P < .01). Regarding the immune status, there was a significant difference from the CD4 count at 1-year follow-up (73 v 335, P = .01). The CD4/CD8 rate were significant different before QT (0.23 v 0.13, P = .01) and at 1-year follow-up (0.12 v 0.32, P = .03.). The estimated 5-year OS rate was significantly lower (P = .0001) for the non-HAART group (41.7%; 95% CI, 25.9 to 56.9) compared with the HAART group (79.3%; 95% CI, 66.8 to 87.5). In the multivariate model for OS, full-HAART regimen and previous diagnosis of HIV/AIDS (P < .01) were significantly associated with longer survival. CONCLUSION: Clinical and demographic characteristics of our patients are compatible with the literature, but we report a higher rate of gastrointestinal involvement. Furthermore, our findings provide evidence for the importance of HAART and its ability to reduce KS-related mortality.

Antifungal Prophylaxis With Posaconazole in Immunocompromised Children Younger Than 13 Years.

OBJECTIVE: Prophylaxis with posaconazole (PP) is effective in the prevention of invasive fungal infections in immunocompromised adult patients. However, evaluation of its effectiveness and safety in children is limited. The aim of the study was to describe the use of posaconazole as antifungal prophylaxis in children. METHODS: We reviewed the medical records of immunocompromised patients younger than 13 years with hematologic diseases and post hematopoietic stem cell transplant (HSCT) who received antifungal PP at the Instituto Nacional de Salud del Niño San Borja (INSN-SB) in Lima, Peru, from January 2014 to December 2018. RESULTS: Fifty-six courses of PP were identified in 47 patients with a median age of 7.5 years (IQR, 4-10), 51.6% (n = 24) of whom were female. The main underlying medical conditions were aplastic anemia (n = 19, 33.9%), acute lymphoblastic leukemia (n = 18, 32.1%), acute myeloid leukemia (n = 14, 25.0%), and 34.1% had undergone HSCT. The median dose of posaconazole was 13.62 mg/kg/day (IQR, 12.0-16.8), and the median duration of PP was 24 days (IQR, 16-82). Gastrointestinal symptoms included abdominal pain (17.9%), nausea (16.1%), diarrhea (7.1%), and vomiting (3.6%). Elevated alanine aminotransferase and aspartate aminotransferase levels were observed in 9/35 patients (25.7%) and 10/51 (19.6%) patients, respectively. Five cases of breakthrough fungal infection were identified (8.9%). CONCLUSIONS: Patients younger than 13 years who received PP showed an increase in transaminase values, and the development of breakthrough fungal infections.

Paracoccidioidomicosis sistémica con compromiso del apéndice cecal en un niño: reporte de caso / Systemic paracoccidioidomycosis with compromise of the cecal appendix in a child: case report

RESUMEN La paracoccidioidomicosis es la micosis sistémica más prevalente en Latinoamérica. En niños la presentación clínica más frecuente es la forma juvenil o aguda/subaguda, que compromete principalmente los ganglios linfáticos y en menor proporción los órganos gastrointestinales. Presentamos el caso de un paciente de 10 años, sin comorbilidades, con dolor agudo en fosa iliaca derecha; además de historia de un mes de evolución de diarrea, fiebre, pérdida de peso e hipereosinofilia. Fue diagnosticado de apendicitis aguda secundaria a un cuadro de paracoccidioidomicosis sistémica, mediante histopatología del apéndice cecal y ganglios mesentéricos. Tuvo respuesta favorable al tratamiento con anfotericina B liposomal. A pesar de que la paracoccidioidomicosis sistémica con compromiso del apéndice cecal es infrecuente, debe considerarse como parte de los diagnósticos diferenciales en niños con linfadenomegalias generalizadas y procedentes de áreas endémicas.

ABSTRACT Paracoccidioidomycosis, the most prevalent systemic mycosis in Latin America. In children the most common clinical presentation is the juvenile or acute/subacute form, which mainly involves the lymph nodes and in a lesser proportion the gastrointestinal organs. We present the case of a 10-year-old patient, without comorbidities, who presented acute right iliac fossa pain; in addition to a history of 1 month of evolution of diarrhea, fever, weight loss, and hypereosinophilia. Was diagnosed of acute appendicitis due to systemic paracoccidioidomycosis, through histopathology of the cecal appendix and mesenteric lymph nodes. Although systemic paracoccidioidomycosis with involvement of the cecal appendix is ​​rare, it should be considered as part of the differential diagnoses in children and young adults with generalized lymphadenomegaly from endemic areas.

Prognostic factors in HIV-positive patients with non-Hodgkin lymphoma: a Peruvian experience.

BACKGROUND: Non-Hodgkin lymphoma (NHL) is the most common cancer in people with HIV. Although 95% of HIV patients are in developing countries like Peru, the majority of these studies have been conducted in developed countries. In this study we aim to evaluate prognostic factors associated with outcomes in HIV positive patients undergoing systemic therapy for treatment of NHL. METHODS: This retrospective study includes patients with NHL seen in the Instituto Nacional de Enfermedades Neoplasicas (INEN) between 2004 to 2014. Patients were divided into two groups: antiretroviral therapy (ART) -naïve (n = 34) and those previously treated, ART-exposed (n = 13), at the time of diagnosis. All patients received chemotherapy and ART. The medical records were reviewed. Data were analyzed using t-test and chi-square test. Survival curves were estimated by the Kaplan-Meier method and comparison was done by log-rank test. Multivariate analysis for overall survival (OS) was performed with the Cox proportional hazard regression model. RESULTS: All ART-exposed patients were from the capital city (p = 0.039); they had significantly lower hemoglobin levels compared to ART-naïve patients (p = 0.026). The median OS was 47.7 months with a 5-yr OS of 36.1%. The median OS for ART naïve patients was significantly higher than that for ART-exposed patients (57.05 and 21.09 months, respectively; p = 0.018). Advanced stage and low serum albumin were associated with lower OS in both groups. Age > 60 was associated with worse outcomes in the ART-naïve cohort. CONCLUSIONS: Advanced stage, low serum albumin and previous ART treatment were the primary prognostic factors associated with poorer outcomes in patients with NHL and HIV infection. In ART-naïve patients, age > 60 was associated with worse outcomes but in this cohort, older patients still had better overall outcomes than ART-exposed patients.
