Early Detection of Cancer and Precancerous Lesions in Persons with HIV through a Comprehensive Cancer Screening Protocol.

BACKGROUND: Non-AIDS defining malignancies present a growing challenge for persons with HIV (PWH), yet tailored interventions for timely cancer diagnosis are lacking. The Spanish IMPAC-Neo protocol was designed to compare two comprehensive cancer screening strategies integrated into routine HIV care. This study reports baseline data on the prevalence and types of precancerous lesions and early-stage cancer among participants at enrolment. Acceptability of the procedure was additionally assessed. METHODS: Cross-sectional analysis of a comprehensive screening protocol to detect precancer and cancer. The readiness of healthcare providers to implement the protocol was evaluated using a validated 4-item survey. RESULTS: Among the 1430 enrolled PWH, 1172 underwent 3181 screening tests, with positive findings in 29.4% of cases, leading to further investigation in 20.7%. Adherence to the protocol was 84%, with HIV providers expressing high acceptability (97.1%), appropriateness (91.4%), and feasibility (77.1%). A total of 145 lesions were identified in 109 participants, including 60 precancerous lesions in 35 patients (3.0%), 9 early-stage cancers in 9 patients (0.8%), and 76 low-risk lesions in 65 subjects (5.5%). Adverse events related to screening occurred in 0.8% of participants, all mild. The overall prevalence of cancer precursors or early-stage cancer was 3.8% (95% CI, 2.74%-5.01%), with highest rates observed in individuals screened for anal and colorectal cancers. CONCLUSIONS: The baseline comprehensive cancer screening protocol of the IMPAC-Neo study successfully identified a significant proportion of PWH with precancerous lesions and early-stage cancer. High adherence rates and positive feedback from providers suggest effective implementation potential in real-world healthcare settings.

Mortality and COVID Infection: Predictors of Mortality 10 Months after Discharge.

BACKGROUND: The long-term survival of patients hospitalized with COVID-19 and the factors associated with poorer survival months after infection are not well understood. The aims of the present study were to analyze the overall mortality 10 months after admission. METHODS: 762 patients with COVID-19 disease were included. Patients underwent a complete clinical evaluation, routine laboratory analysis and chest X-ray. Data collected included demographic and clinical data, such as vascular risk factors, tobacco or alcohol use, comorbidity, and institutionalization. RESULTS: Ten-month mortality was 25.6%: 108 deaths occurred in-hospital, while 87 patients died after discharge. In-hospital mortality was independently related to NT-proBNP values > 503.5 pg/mL [OR = 4.67 (2.38-9.20)], urea > 37 mg/dL [3.21 (1.86-7.31)] and age older than 71 years [OR = 1.93 (1.05-3.54)]. NT-proBNP values > 503.5 pg/mL [OR = 5.00 (3.06-8.19)], urea > 37 mg/dL [3.51 (1.97-6.27)], cognitive impairment [OR = 1.96 (1.30-2.95), cancer [OR = 2.23 (1.36-3.68), and leukocytes > 6330/mm3 [OR = 1.64 (1.08-2.50)], were independently associated with long-term mortality. CONCLUSIONS: the risk of death remains high even months after COVID-19 infection. Overall mortality of COVID-19 patients during 10 months after hospital discharge is nearly as high as that observed during hospital admission. Comorbidities such as cancer or cognitive impairment, organ dysfunction and inflammatory reaction are independent prognostic markers of long-term mortality.

Vancomycin versus daptomycin for the treatment of confirmed gram-positive catheter-related bloodstream infections in oncology patients.

OBJECTIVE: To analyse the effectiveness and safety of daptomycin versus vancomycin on the management catheter-related bloodstream  nfections in oncology patients. METHOD: A retrospective study was carried out including all patients admitted  at the Medical Oncology Unit between 2010 and 2018 with positive blood  cultures confirmed catheter-related bloodstream infections due to gram- positive microorganism, who were treated with either vancomycin or  daptomycin. The primary end point was all cause 30-days mortality, 30-days  hospital readmission and length of hospital stay (length of hospital stay). Results: A total of 70 patients with catheter-related bloodstream infections were included in the present study: vancomycin was administered to  61.4% (n = 43) and daptomycin to 38.6% (n = 27) of  patients. 78.5% (n = 55) of isolated bacteria showed a vancomycin minimum  inhibitory concentration ≤ 1 µg/ml. No differences were observed  between the two groups of patients regarding the 30-day mortality rate rate  (32.6% [n = 14] versus 29.6% [n = 8]; p = 0.797), the 30-day re-admission rate (30.2% [n = 13] versus 29.6% [n = 8]; p = 0.957) or the length of  hospital stay (18.9 versus 16.5 days; p = 0.562). Nephrotoxicity rate was  equivalent in both groups: a 7% (n = 3) of vancomycin goup versus a 7.4% (n  = 2) of daptomycin group (p = 0.946). CONCLUSIONS: Our results show that both antibiotics are equivalent in their  safety and effectiveness. Therefore, vancomycin should continue being the  treatment of chose for gram-positive catheter-related bloodstream infections,  in particular at hospital centres with a low prevalence of strains that show  diminished susceptibility to vancomycin.

OBJETIVO: Analizar la eficacia y seguridad de la daptomicina frente a la  vancomicina en el tratamiento de las infecciones del torrente sanguíneo asociadas a catéter vascular en pacientes oncológicos.Método: Se realizó un estudio retrospectivo que incluyó a los pacientes ingresados en la Unidad de Oncología-Médica entre 2010-2018 con infección del torrente sanguíneo asociada a catéter vascular causada por  grampositivos, y que fueron tratados con vancomicina o daptomicina. Como  objetivos principales se determinaron la tasa de mortalidad por todas las  causas a los 30 días, el reingreso hospitalario a los 30 días y la duración de la  estancia hospitalaria.

El 78,5% (n = 55) de las  bacterias aisladas presentaron una concentración mínima inhibitoria de  vancomicina ≤ 1 µg/ml. No se observaron diferencias entre ambos grupos de  pacientes en cuanto a la tasa de mortalidad a 30 días (32,6% [n = 14]  frente al 29,6% [n = 8]; p = 0,797), la tasa de reingreso a 30 días (30,2% [n  = 13] frente al 29,6% [n = 8]; p = 0,957) o la duración de la hospitalización (18,9 frente a 16,5 días; p = 0,562). La tasa de nefrotoxicidad fue equivalente  en ambos grupos: 7% (n = 3) para vancomicina frente al 7,4% (n = 2) para  daptomicina (p = 0,946). CONCLUSIONES: Nuestros resultados muestran que ambos antibióticos son equivalentes en su seguridad y eficacia. Por ello, vancomicina debería seguir siendo el tratamiento de elección para la infección del torrente sanguíneo asociada a catéter vascular, especialmente en centros con  una baja prevalencia de cepas con una susceptibilidad disminuida a  ancomicina.

Bartonella Endocarditis in Spain: Case Reports of 21 Cases.

Blood culture negative endocarditis (BCNE) is frequent in infective endocarditis (IE). One of the causes of BCNE is fastidious microorganisms, such as Bartonella spp. The aim of this study was to describe the epidemiologic, clinical characteristics, management and outcomes of patients with Bartonella IE from the "Spanish Collaboration on Endocarditis-Grupo de Apoyo al Manejo de la Endocarditis infecciosa en España (GAMES)"cohort. Here we presented 21 cases of Bartonella IE. This represents 0.3% of a total of 5590 cases and 2% of the BCNE from the GAMES cohort. 62% were due to Bartonella henselae and 38% to Bartonella quintana. Cardiac failure was the main presenting form (61.5% in B. hensalae, 87.5% in B. quintana IE) and the aortic valve was affected in 85% of the cases (76% in B. henselae, 100% in B. quintana IE). Typical signs such as fever were recorded in less than 40% of patients. Echocardiography showed vegetations in 92% and 100% of the patients with B. henselae and B. quintana, respectively. Culture was positive only in one patient and the remaining were diagnosed by serology and PCR. PCR was the most useful tool allowing for diagnosis in 16 patients (100% of the studied valves). Serology, at titers recommended by guidelines, only coincided with PCR in 52.4%. Antimicrobial therapy, in different combinations, was used in all cases. Surgery was performed in 76% of the patients. No in-hospital mortality was observed. One-year mortality was 9.4%. This article remarks the importance for investigating the presence of Bartonella infection as causative agent in all BCNE since the diagnosis needs specific microbiological tools and patients could benefit of a specific treatment.

Prediction of recurrent clostridium difficile infection at the bedside: the GEIH-CDI score.

Recurrence of Clostridium difficile infection (CDI) has major consequences for both patients and the health system. The ability to predict which patients are at increased risk of recurrent CDI makes it possible to select candidates for treatment with new drugs and therapies (including fecal microbiota transplantation) that have proven to reduce the incidence of recurrence of CDI. Our objective was to develop a clinical prediction tool, the GEIH-CDI score, to determine the risk of recurrence of CDI. Predictors of recurrence of CDI were investigated using logistic regression in a prospective cohort of 274 patients diagnosed with CDI. The model was calibrated using the Hosmer-Lemeshow test. The tool comprises four factors: age (70-79 years and ≥80 years), history of CDI during the previous year, direct detection of toxin in stool, and persistence of diarrhea on the fifth day of treatment. The functioning of the GEIH-CDI score was validated in a prospective cohort of 183 patients. The area under the ROC curve was 0.72 (0.65-0.79). Application of the tool makes it possible to select patients at high risk (>50%) of recurrence and patients at low risk (<10%) of recurrence. GEIH-CDI score may be useful for clinicians treating patients with CDI.

Prognostic factors of infective endocarditis in patients on hemodialysis: A case series from a National Multicenter Registry.

BACKGROUND: Infective endocarditis (IE) is a severe complication associated with high mortality. OBJECTIVES: To examine the clinical characteristics of IE in hemodialysis (HD) patients and to determine prognostic factors related to HD. METHODS: From January 2008 to April 2015, 2488 consecutive patients with definite IE were included. Clinical characteristics of IE patients on HD were compared with those of IE patients who were not on HD. RESULTS: A total of 126 patients (63% male, median age: 66years; IQR: 54-74years) with IE (5.1%) were on HD. Fifty-two patients died during hospitalization (41%) and 17 additional patients (14%) died during the first year. The rate of patients who underwent surgery during hospitalization was lower in HD patients (38 patients, 30%) than in non-HD patients (1177 patients, 50%; p<0.001). Age >70years (OR: 4.1, 95% CI: 1.7-10), heart failure (OR: 3.3, 95% CI: 1.4-7-6), central nervous system (CNS) vascular events (OR: 6.7, 95% CI: 2.1-22) and septic shock (OR: 4.1, 95% CI: 1.4-12.1) were independently associated with fatal outcome in HD patients. Of the 38 patients who underwent surgery, 15 (39.5%) died during hospitalization. CONCLUSIONS: HD patients with IE present a high mortality. Advanced age and complications, such as heart failure, CNS stroke or septic shock, are associated with mortality.

Short Communication: Efficacy and Safety of Treatment Simplification to Lopinavir/Ritonavir or Darunavir/Ritonavir Monotherapy: A Randomized Clinical Trial.

Antiretroviral treatment simplification strategies based on monotherapy with darunavir/ritonavir (DRV/r) or lopinavir/ritonavir (LPV/r) have not been directly compared in clinical trials. We evaluated the 48-week efficacy and safety of DRV/r versus LPV/r monotherapy as a treatment simplification strategy in a multicenter, randomized open-label study. Maintenance of viral suppression in cerebrospinal fluid (CSF) and semen was also explored. An intention to treat efficacy analysis was performed considering missing equals to failure (ITT:M = F). Virological failure (VF) was defined as a confirmed increase in plasma HIV-1 RNA >50 copies/mL. A total of 75 patients were enrolled: 40 were allocated to DRVr and 33 to LPVr. In the ITT: M = F analysis, 77.5% of patients on DRV/r and 66.6% of patients on LPV/r maintained HIV-1 RNA <50 copies/mL at week 48 (p = .302, treatment difference 10.8% [95% CI,-12.6 to 34.2]). In the DRV/r arm, no patients developed VF and 15.0% discontinued treatment due to adverse events. In the LPV/r arm, 2 (6.1%) patients developed VF and 18.2% discontinued monotherapy due to adverse events. Gastrointestinal disturbances were experienced by 18.2% and 2.5% of patients in the LPV/r and DRV/r arms, respectively (p = .019). Two patients had detectable HIV-1 RNA ≥50 copies/mL in CSF or semen. Monotherapy with LPV/r or DRV/r seems to be virologically effective in selected HIV-1-infected patients with sustained viral suppression. Differences between both regimens seem driven mainly by the better tolerability profile of DRV/r.
