ABSTRACT

OBJECTIVE: Performing of diagnostic test simple using samples not invasive in the diagnosis of visceral leishmaniasis (VL) may be very beneficial, being necessary comparing to traditional methods. The objective of this study was to know the reliability of test KAtex in the urine of patients with suspicion of VL. METHODS: Retrospectively were reviewed the medical histories of patients with suspected of VL to which are performed the test between 2009 and 2015. For its analysis were selected the patients to which is them had made study of the parasite in bone marrow. RESULTS: A total of 110 patients were studied, and bone marrow biopsy for research of Leishmania was performed in 44 (40%). In these patients the sensitivity of the test was 50%, the specificity of 96.7%, positive predictive value of 87.5% and negative predictive value of 80.5%. CONCLUSIONS: KAtex antigenuria sensitivity is too low recommending it as a unique method in the detection of VL in our medium.

ABSTRACT

In April 2015, the Spanish National Health System (SNHS) developed a national strategic plan for the diagnosis, treatment, and management of hepatitis C virus (HCV). Our aim was to analyze the impact of this on human immunodeficiency virus (HIV)-infected patients included in the HERACLES cohort during the first 6 months of its implementation. The HERACLES cohort (NCT02511496) was set up in March 2015 to evaluate the status and follow-up of chronic HCV infection in patients co-infected with HIV in the south of Spain. In September 2015, the data were analyzed to identify clinical events (death, liver decompensation, and liver fibrosis progression) and rate of treatment implementation in this population. The study population comprised a total of 3474 HIV/HCV co-infected patients. The distribution according to liver fibrosis stage was: 1152 F0-F1 (33.2 %); 513 F2 (14.4 %); 641 F3 (18.2 %); 761 F4 (21.9 %); and 407 whose liver fibrosis was not measured (12.3 %). During follow-up, 248 patients progressed by at least one fibrosis stage [7.1 %; 95 % confidence interval (CI): 6.3-8 %]. Among cirrhotic patients, 52 (6.8 %; 95 % CI: 5.2-8.9 %) developed hepatic decompensation. In the overall population, 50 patients died (1.4 %; 95 % CI: 1.1-1.9 %). Eight hundred and nineteen patients (23.56 %) initiated interferon (IFN)-free treatment during follow-up, of which 47.8 % were cirrhotic. In our study, during 6 months of follow-up, 23.56 % of HIV/HCV co-infected patients included in our cohort received HCV treatment. However, we observed a high incidence of negative short-term outcomes in our population.

ABSTRACT

Cross-sectional study comparing seminal human immunodeficiency virus type 1 (HIV-1) shedding in patients receiving boosted protease inhibitor monotherapy (mtPI/rtv) (n = 66) versus triple therapy (TT) (n = 61). Seminal HIV-1 shedding rates in patients with undetectable plasma HIV-RNA were 16.0% on mtPI/rtv compared with 28.6% on TT (p 0.173). Aviraemic status and time on viral suppression were independently associated with lack of seminal HIV-1 shedding. During TT, non PI/rtv-based regimens were associated with a better control of HIV infection in semen despite similar time on viral suppression. The use of mtPI/rtv in well-controlled patients is not associated with increased seminal HIV excretion compared with TT.

ABSTRACT

The implementation of hepatitis C (HCV) direct-acting antiviral drugs is prioritized in several populations in which its application provides the most immediate and impactful benefit. In this scenario, a precise knowledge of the situation of human immunodeficiency virus (HIV)/HCV chronic co-infection is required to adequately address this disease. This cross-sectional study was performed in 21 hospitals in Andalusia (Spain). The study population consisted of HIV-infected patients with an active HCV chronic infection who were not receiving HCV treatment at the time of inclusion. A total of 13,506 HIV-infected patients were included in the study. Of them, 2561 (18.9 %) presented chronic HCV infection. The majority of the patients included were on highly active antiretroviral therapy (HAART; 96.2 %), showed plasma levels with an undetectable HIV viral load (92.5 %), and had a good immunological status (median CD4+ cell count of 486 cells/mL). The HCV genotype distribution was as follows: 58.1 % were genotype 1, 1.1 % were genotype 2, 16.1 % were genotype 3, and 22.1 % were genotype 4 (2.6 % were missing data). In total, 24.8 % of the patients showed liver fibrosis stage F0-F1, 27.9 % showed stage F2, 16.7 % showed stage F3, and 21 % showed stage F4 (9.6 % were missing data). With regards to previous HCV treatment experiences, 68.05 % of the patients were naïve and 31.95 % had failed to respond to a previous treatment. The burden of HCV/HIV co-infected patients in our population was reported as one in five HIV-infected patients requiring HCV treatment. The implementation of extra resources to face this important health challenge is mandatory.

ABSTRACT

BACKGROUND: The factors that influence liver fibrosis progression in patients co-infected with human immunodeficiency virus/hepatitis C virus (HIV/HCV) are not completely understood. It is not known if insulin resistance (IR), a condition that promotes liver fibrosis in HCV mono-infected individuals, is one of these factors. OBJECTIVE: To evaluate the association between IR and liver stiffness (LS). DESIGN: Multicentre cross-sectional study. PATIENTS: 330 patients co-infected with HIV/HCV. METHODS: LS was assessed by transient elastography, which has shown a high accuracy to predict significant fibrosis in patients co-infected with HIV/HCV. The outcome variable of the study was LS. Patients with LS> or =9 kPa were considered as having significant fibrosis. IR was calculated using the HOMA method. RESULTS: LS was > or =9 kPa in 150 (45%) patients. HOMA correlated with LS (Spearman's rho correlation coefficient, 0.37; p<0.0001). The median (Q1-Q3) HOMA in patients with LS> or =9 kPa was 3.30 (2.17-5.16) while it was 2.09 (1.37-3.22) in patients with LS <9 kPa (p<0.0001). Ninety-six (39%) individuals with a HOMA <4 and 54 (63%) with a HOMA > or =4 showed LS> or =9 kPa (p<0.0001). Analyses after excluding patients with cirrhosis yielded similar results. After multivariate analyses, age > or =40 years (adjusted odds ratio (AOR), 1.85; 95% confidence interval (CI), 1.03 to 3.29; p = 0.03), CD4 cell count <200 cells/ml (AOR, 3.45; 95% CI, 1.67 to 7.11; p = 0.001), hepatitis B virus co-infection (AOR, 9.25; 95% CI, 2.42 to 35.31; p = 0.001), and HOMA > or =4 (AOR, 5.33; 95% CI, 2.70 to 10.49; p<0.0001) were the independent predictors of LS> or =9 kPa. CONCLUSION: IR is associated with LS in patients co-infected with HIV/HCV.

ABSTRACT

OBJECTIVES: This study aims to analyse how a wide group of clinical, social, demographic and psychological factors are related to both physical and mental quality of life in HIV + patients. DESIGN: A cross-sectional study was carried out of 320 HIV + patients in antiretroviral treatment who attended infectious diseases units in four hospitals in the region of Andalusia (Spain). METHODS: Health-Related Quality of Life was measured by the MOS-HIV. Included as independent variables were: sociodemographic variables, variables related to antiretroviral therapy, psychosocial variables like social support (Duke-UNC-11) and psychological morbidity (GHQ-28), variables related to main risk behaviours and clinical variables. RESULTS: In the multiple linear regression analysis, a better PHS quality of life was found to be associated with the absence of mental illness, social support, not being an intravenous drug user and using more than one type of non-injectable drug. A better quality of life, in mental terms, was found to be associated with fewer years as a non-intravenous drug user, having social support, absence of mental illness, not being an intravenous drug user taking only one additional pill, not having any difficulty in taking the medication, and being female. CONCLUSIONS: The study of other non-biological factors that may be related to quality of life has been limited practically to social support and the emotional state. This study highlights the importance of these factors independently from the clinical state, as well as the existence of other psychological and behavioural factors that are also related.
