Background Literature on severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infection in cancer patients is scarce in Latin America. This population seems to have a higher risk for adverse outcomes. This study aims to correlate clinical characteristics with outcomes in patients with cancer. Methods We included all patients with cancer and confirmed SARS‐CoV‐2 infection from April 19 to December 31, 2020, at the Instituto Nacional de Cancerologia, Mexico. Clinical information was obtained from medical and epidemiological records. For the association between variables and hospitalization, invasive mechanical ventilation (IMV), and mortality, univariate and multivariate logistic regression were performed; odds ratios and 95% confidence intervals were calculated. Results Four hundred thirty‐three patients were included; 268 (62%) were female, the median age was 55 years. One hundred thirty‐five (31%), 131 (30%), and 93 (21%) patients had obesity, hypertension, and diabetes mellitus (DM), respectively. Three hundred forty‐one (79%) had solid cancer. One hundred seventy (39%) had advanced cancer. Two hundred (46%) patients were hospitalized. Age ( p < 0.01), male gender ( p = 0.03), hematological malignancies (HM) ( p = 0.04) and advanced cancer ( p = 0.03) increased the risk for hospital admission. Forty‐five (10%) patients required IMV. Age ( p = 0.02); DM ( p = 0.04); high C‐reactive protein ( p < 0.01), and lactate dehydrogenase ( p = 0.03) were associated with IMV. Mortality within 30 days after diagnosis was 18% (76 cases). Associated characteristics were age ( p = 0.04) and low albumin ( p < 0.01). Conclusions In this study, patients with cancer showed higher mortality, need for hospitalization, and IMV compared with other non‐cancer cohorts. We did not find an increased risk in mortality for HM. Although our cohort was younger than others previously reported, age was a strong predictor of adverse outcomes. Variables associated with IMV and death were similar to those previously described in cancer patients with COVID‐19.
In individuals with HIV/AIDS, 47% of the deaths are attributed to invasive fungal infections (IFIs), despite antiretroviral (ARV) therapy. This is a retrospective study carried out in the Hospital Regional de Alta Especialidad Oaxaca (HRAEO), southwest Mexico, where IFIs that occurred during 2016–2017 are described. A total of 55 individuals were included. Histoplasmosis (36%) and possible-IFIs in neutropenic fever (20%) were the most frequent cases, followed by cryptococcosis (14%). The HIV/AIDS subpopulation corresponded with 26 cases (47%), all from an indigenous origin. The incidence of IFIs among them was 24% (95% CI = 15–33%). The CD4+ T cells median was 35 cells/mL (IQR 12–58). Four cases (15%) of unmasking IRIS were identified, three of histoplasmosis and one coccidioidomycosis. Co-infections were found in 52% (12/23), and tuberculosis in 50% (6/12) was the most frequent. The mortality rate was 48%. The general characteristics of the HIV individuals who died were atypical pneumonia (70% vs. 9%, p = 0.01), acute kidney injury, (70% vs. 9%, p = 0.008) and ICU stay (80% vs. 9%, p = 0.002). In conclusion, IFIs are diagnosed in one out of four individuals with HIV/AIDS along with other complicated infectious conditions, leading to major complications and a high mortality rate.
Background Disseminated Mycobacterium avium complex (MAC) infection occurs in 20-40% of patients with < 50 CD4/mm3. Data describing central nervous MAC involvement (CNS-MAC) in disseminated infection is scarce. Methods We conducted a retrospective case series in the outpatient infectious diseases clinic in the hospital “Dr. Manuel Gea Gonzales” in Mexico City. We reviewed all records from October 2020 to May 2021 and identified all culture proven MAC infections. Results We found 7 cases of MAC, with disseminated infection (positive bone marrow cultures) with 3 out of those 7 meeting our definition for CNS-MAC (positive cerebrospinal fluid culture). All cases of CNS-MAC infection occurred in patients with < 50 CD4/mm3 and recent HIV diagnosis (1-4 months) that were referred to our institution with consumptive syndrome and fevers. All patients were receiving antiretroviral treatment (ART) with BIC/FTC/TAF and initiated ART in less than 1 month since HIV diagnosis. Opportunistic infections were ruled-out at the moment of CNS-MAC diagnosis (criptococcal meningitis, cytomegalovirus retinitis, tuberculosis and histoplasmosis). All patients exhibited non-specific neurologic symptoms at arrival (headache and bradipsiquia) mixed with more severe symptoms (one case of ataxia, one case of vertigo, one case of III nerve palsy). All patients were treated with Clarithromycin/Levofloxacin/Ethambutol. Two patients achieved symptom remission and 1 patient was lost to follow-up. Of important note, all CSF analysis and CNS imaging studies carried-out were normal. No MAC bacilli were identified with direct Ziel-Neelsen staining of CSF. Conclusion We found a high proportion of CNS-MAC in patients with disseminated MAC infection (42.8%) during the study period. All patients presented CNS symptoms and normal CSF characteristics. In our setting, patients with suspected disseminated MAC infection CD4 counts < 50 cells/mm3 might represent a specific population that could benefit from routine targeted diagnostic test at presentation in order to establish CNS involvement.

Background Literature on SARS-CoV-2 infection in cancer patients is scarce in Latin America. This population seems to have a higher risk for adverse outcomes. This study aims to correlate clinical characteristics with outcomes in patients with cancer in a referral center in Mexico. Methods We included patients with cancer and confirmed SARS-CoV-2 infection, from April, 19 to December 30, 2020, at the Instituto Nacional de Cancerología, Mexico. Clinical information was obtained from medical and epidemiological records. We conducted a descriptive analysis. For the association between variables with hospitalization, invasive mechanical ventilation (IMV), and mortality; univariate and multivariate logistic regression was performed; odds ratios and 95% confidence intervals were calculated. Results Four hundred thirty-three patients were included; 268 (62%) were female, the median age was 55 years. One hundred thirty-five (31%), 130 (30%), and 93 (21%) patients had obesity, hypertension, and diabetes mellitus (DM), respectively. Three hundred forty-one (79%) had solid cancer; 82 (19%) hematological malignancy (HM), and 10 (2%) were under evaluation for cancer diagnosis. One hundred seventy (39%) had advanced or metastatic cancer. One hundred ninety-eight (46%) patients were hospitalized. Risk factors were: age (p= 0.001); woman (p=0.019); HM (p=0.050) and advanced or metastatic cancer (p= 0.041). Fourty-five (10%) patients required IMV. Age (p=0.018); DM (p=0.041); C-Reactive Protein (p= 0.002), and LDH (p= 0.033) were associated with invasive mechanical ventilation. Mortality within 30-days after diagnosis was 19% (82 cases). Associated characteristics were: age (p=0.041); lymphocytes (p=0.049); creatinine (p=0.005) and albumin (p=0.001). Conclusion In this study, patients with cancer showed higher mortality, need of hospitalization, and invasive mechanical ventilation compared with groups of patients without cancer. We did not find an increased risk in mortality for hematological malignancies. Although our cohort was younger than others previously reported, age was a strong predictor of adverse outcomes. Variables associated with IMV and death were similar to those previously described in cancer patients with COVID-19. Disclosures All Authors: No reported disclosures
