Lack of associations of microRNAs with severe NAFLD in people living with HIV: discovery case-control study.

Background & objective: Nonalcoholic fatty liver disease (NAFLD) is highly prevalent in people living with HIV (PLWH) and the expression of some microRNAs could be useful as biomarkers for the diagnosis of NAFLD. The aim of this study was to identify patterns of differential expression of microRNAs in PLWH and assess their diagnostic value for NALFD. Methods: A discovery case-control study with PLWH was carried out. The expression of miRNAs was determined using HTG EdgeSeq technology. Cases were defined as patients with severe NAFLD and controls as patients without NAFLD, characterized using the controlled attenuation parameter (CAP). Cases and controls were matched 1:1 for age, sex, BMI, CD4+ lymphocyte count, active HCV infection, and ART regimen. Results: Serum 2,083 simultaneous microRNA transcripts were analyzed using HTG technology and compared between cases and controls. Forty-five patients, 23 cases, and 22 controls were included in the study. In the analysis of the expression pattern of the 2,083 microRNAs, no differential expression patterns were found between both groups of patients included in the study. Conclusion: Analysis of the microRNA transcriptome profile of nonobese PLWH with severe NAFLD did not appear to differ from that of patients without NAFLD. Thus, microRNA might not serve as a proper biomarker for predicting severe NALFD in this population.

Brief transdiagnostic group intervention for people living with HIV and emotional disorders: feasibility and clinical utility.

Emotional regulation-based transdiagnostic interventions provide positive but limited evidence regarding efficacy with people living with human immunodeficiency virus (HIV). In the present study, 10 participants living with HIV with emotional disorders completed a five-session transdiagnostic group intervention to improve their emotional regulation skills (Unified Protocol). Changes at pre-treatment, post-treatment and three-month follow-up were explored at the population (mean-rank) and the individual level (reliable change index). Compared to pre-treatment, participants improved significantly in anxiety, depression, negative affect and quality of life. Changes were maintained at the three-month follow-up. Emotion regulation, particularly the confusion factor, improved when comparing pre-treatment with the three-month follow-up. At the three-month follow-up, the percentage of normalized scores was the largest in maladjustment (70%), followed by depression, negative affect, and lack of control (50%). All participants indicated high treatment satisfaction and perceived benefits. These promising results suggest that brief emotion regulation interventions might be feasible and effective in the public health settings for people living with HIV suffering emotional disorders.

Efficacy of a comprehensive strategy for the detection and treatment of hepatitis C infection in a population attending addiction centers.

Background and aims: The burden hepatitis C infection in people with history or current drug use suppose a high risk of hepatic complications and transmission infectious disease. This population is poor linked to heath system and is difficult to achieve them and support treatment because they have high rates of lost follow-up. Our aim was to evaluate an intervention for the diagnosis and treatment of chronic hepatitis C and HIV in this population. Methods: Six-hundred and eighty-three people attended in Drugs and Addictions Centers (DAC) were asked to participate in health counseling and provide blood sample for test HCV, HIV, and syphilis from April 2019 to June 2020. Totally 556 subjects were surveyed and tested. All of them were assigned to a patient navigation program to improve health education and linking to the sanitary system. Hepatitis C infection patients were evaluated in an ampliated medical consult to evaluate hepatic stage with transient liver elastography and initiated Direct Acting Antivirals to achieve Sustained Viral Response. Results: Of the 556 patients who agreed to participate in the study, 33 (5.9%) had active HCV infection. Of the 33 patients infected with HCV, three were lost to follow-up once the diagnosis of HCV infection was made. Twenty-eight patients (93.3%) completed treatment and 26 achieved Sustained Viral Response (78.8%). Of the 30 patients, seven (23.3%) had advanced fibrosis, and of these, four (16.6%) had liver cirrhosis. One of the cirrhotic patients had hepatic space-occupying lesions at the baseline evaluation and was diagnosed with hepatocarcinoma. Conclusions: Our study suggests that the implementation of strategies based on personalized intervention models can contribute to the control of HCV infection in DAC users.

Perception of HIV physicians in Spain towards diagnosis and management of neuropsychiatric comorbidities in people with HIV.

OBJECTIVES: Despite the importance of neuropsychiatric comorbidities (NPCs) in people with HIV, the degree of physician compliance with recommendations for diagnosis and management is unknown. This study assessed the perceptions, knowledge, skills, and attitudes of physicians regarding the diagnosis and management of NPCs in people with HIV in hospital settings in Spain. METHODS: This was a cross-sectional study including non-psychiatrist HIV specialist physicians responsible for antiretroviral therapy (ART) prescription and clinical care of ≥50 people with HIV/month, who completed an online survey of 34 questions. RESULTS: The 115 physicians who completed the survey (totally) agreed that assessing mental health was relevant (97.4%) and that NPCs were underdiagnosed (76.6%) and were very/fairly sensitized (67.8%). However, they reported receiving little/no training on the detection of NPCs (64.3%). Physicians considered that patients underreported NPCs (53.9%) and that alcohol (94.8%), recreational substances (97.4%), and tobacco consumption (95.6%) were (very) relevant. Physicians agreed that NPCs were difficult to identify (52.2%) and that few tools were available (53.0%) and failed to use questionnaires (79.1%) and follow guidelines (77.4%) for the detection of NPCs. The main reasons precluding appropriate diagnosis and evaluation were lack of proactive attitudes and specific training and limited visit time. Upon detection of NPCs, physicians referred patients to the in-house psychiatry/psychology centre (61.7%), adjusted ART to minimize interactions (96.5%), and managed NPCs in conjunction with mental health professionals (71.3%). CONCLUSIONS: Physicians in hospital settings in Spain were aware of the relevance of NPC diagnosis and their underdiagnosis. However, they still failed to routinely evaluate NPCs, follow guideline recommendations, and use questionnaires, highlighting opportunities for improved NPC detection and management in people with HIV.

Cardiac valve replacement in patients with antiphospholipid syndrome.

OBJECTIVE: To analyze the results of cardiac valve replacement in a multicenter cohort of patients with antiphospholipid syndrome (APS) and to identify prognostic factors of poor outcome. METHODS: We performed a retrospective analysis of clinical manifestations (cardiac involvement and APS characteristics), operative and early postoperative courses, and long-term followup. All of the patients fulfilled the Sapporo criteria for APS. Logistic regression analyses were performed to identify those variables associated with adverse outcomes. RESULTS: Between 1981 and 2008, 33 valvular replacements were carried out in 32 patients with APS. The mean ± SD age at the time of surgery was 43.09 ± 14.08 years. Thirty patients were women. Primary APS was present in 21 patients. The median followup time after surgery was 33.5 months (range 0-192 months). The mitral valve was the most frequently replaced (22 of 33). Mechanical valve replacement was performed in 23 patients (71.9%). The mortality rate was 12.5% (1 cardiogenic shock, 1 septic shock, 1 following renal transplantation, and 1 hemorrhagic stroke). Fourteen patients experienced 20 complications (8 major bleeding, 5 thrombotic events, 2 valvular deteriorations, 2 third-degree atrioventricular block, 1 endocarditis, 1 cardiac tamponade, and 1 cardiac failure). Fifty percent of the patients had an uneventful outcome. CONCLUSION: Morbidity and mortality were high in APS patients undergoing valve replacement surgery. Most complications were related to thrombosis and bleeding. Anticoagulation must be carefully monitored to prevent hemorrhagic and thrombotic complications.

Mortality risk factors in patients with zygomycosis: a retrospective and multicentre study of 25 cases.

AIM: To investigate mortality risk factors in patients with zygomycosis. PATIENTS AND METHODS: Retrospective case history review of patients diagnosed with proven zygomicosis in 17 centres in Spain. We compared demographics and risk factors in patients who survived, and in those who died. RESULTS: We identified twenty-five patients with proven zygomycosis. The primary site of infection was rhino-orbito-cerebral (28%) and disseminated (20%) or cutaneous/soft infections (20%) of the patients. Eleven patients (44%) received preemptive or empirical antifungal treatment; of these patients, 4 received liposomal amphotericin B, 1 received amphotericin B lipid complex, and 6 received other antifungals. The overall mortality rate was 72%. In the univariate analysis factors associated with an increased risk of death were the presence of a haematological malignancy (P=.03), neutropenia (P=.03) and monocytopenia (P=.008). CONCLUSION: Our study supports previous research that has documented a high mortality rate among patients with invasive zygomycosis, especially among those with an underlying haematological malignancy, and the need for a rapid initiation of an effective antifungal treatment.

Long-term (4 years) efficacy of lopinavir/ritonavir monotherapy for maintenance of HIV suppression.

OBJECTIVES: Data are scarce on the long-term efficacy of lopinavir/ritonavir monotherapy for the maintenance of HIV suppression. Four years of results of patients randomized to monotherapy in the Only Kaletra (OK) pilot clinical trial are presented. PATIENTS AND METHODS: Twenty-one HIV-infected patients with suppressed HIV replication (<50 copies/mL) for at least 6 months and without previous failure while receiving a protease inhibitor-based regimen started lopinavir/ritonavir monotherapy. Follow-up was performed within the OK pilot clinical trial during the first 2 years and according to routine clinical practice during the 3rd and 4th years. RESULTS: Fourteen patients (67%) remain on monotherapy and with RNA <50 copies/mL (intention-to-treat analysis, with missing patients scored as failures). Five patients (24%) had virological rebound and all of them were successfully re-suppressed by adding two nucleosides. No major protease inhibitor mutations were found. CONCLUSIONS: Our data support the long-term efficacy and safety of lopinavir/ritonavir monotherapy for the maintenance of HIV suppression, a finding that must be confirmed in larger studies.
