Predictors of attrition among adults in a rural HIV clinic in southern Mozambique: 18-year retrospective study.

HIV remains a major cause of morbidity and mortality for people living in many low-income countries. With an HIV prevalence of 12.4% among people aged over 15 years, Mozambique was ranked in 2019 as one of eight countries with the highest HIV rates in the world. We analyzed routinely collected data from electronical medical records in HIV-infected patients aged 15 years or older and enrolled at Carmelo Hospital of Chokwe in Chokwe from 2002 to 2019. Attrition was defined as individuals who were either reported dead or lost to follow-up (LTFU) (≥ 90 days since the last clinic visit with missed medical pick-up after 3 days of failed calls). Kaplan-Meier survival curves and Cox regression analyses were used to model the incidence and predictors of time to attrition. From January 2002 to December 2019, 16,321 patients were enrolled on antiretroviral therapy (ART): 59.2% were women, and 37.9% were aged 25-34 years old. At the time of the analysis, 7279 (44.6%) were active and on ART. Overall, the 16,321 adults on ART contributed a total of 72,987 person-years of observation. The overall attrition rate was 9.46 per 100 person-years. Cox regression showed a higher risk of attrition in those following an inpatient regimen (hazard ratio [HR] 3.18, 95% confidence interval [CI] 2.89-3.50; p < 0.001), having CD4 counts under 50 cells/µL (HR 1.91, 95% CI 1.63-2.24, p < 0.001), receiving anti-TB treatment within 90 days of ART initiation (HR 6.53, 95% CI 5.72-7.45; p < 0.001), classified as WHO clinical stage III (HR 3.75, 95% CI 3.21-4.37; p < 0.001), and having Kaposi's sarcoma (HR 1.99, 95% CI 1.65-2.39, p < 0.001). Kaplan-Meier analysis showed that patients with CD4 counts of less than 50 cells/µL on ART initiation had a 40% lower chance of survival at 18 years. Low CD4 cell counts, ART initiation as an inpatient, WHO clinical stage III, and anti-tuberculosis treatment within 90 days of ART initiation were strongly associated with attrition. Strengthening HIV testing and ART treatment, improving the diagnosis of tuberculosis before ART initiation, and guaranteed psychosocial support systems are the best tools to reduce patient attrition after starting ART.

Heterogeneity in Cystic Echinococcosis Management Among Spanish Centers: Results from a National Survey.

The aim of the study was to evaluate the availability of different procedures, diagnostic tests, and treatments, as well as the procedures and techniques used in the management of cystic echinococcosis (CE) in Spain. This was a cross-sectional study performed from September to December 2018 in Spain. A survey directed to CE-treating clinicians was conducted to collect information regarding the center characteristics and the different protocols of management followed. Thirty-nine centers among 76 contacted centers participated in the survey, most of them belonging to the public health system and attending both adult and children. The median number of patients with CE attended during the last three years per center was 15. Percutaneous techniques were used only in seven centers, and surgery was the most frequently used therapeutic approach. Drugs and duration of treatment (both when administered exclusively or when combined with surgery/puncture, aspiration, injection, and reaspiration) were very variable depending on the centers. There is a high variability in the management of CE among Spanish centers. These results stress the importance of promoting the diffusion of existing knowledge, adapting the WHO recommendations to our setting, and referring patients to referral centers at a national level.

Imported cysticercosis in Spain: A retrospective case series from the +REDIVI Collaborative Network.

BACKGROUND: Neurocysticercosis (NCC) is the most common parasitic neurological disease worldwide and a major cause of epilepsy. Spain is the country reporting the highest number of NCC imported cases in Europe. METHODOLOGY: Retrospective case series of NCC patients registered in the +REDIVI Network from October 1, 2009 to July 2018. A specific questionnaire, including clinical and diagnostic characteristics, was created and sent to the collaborator centers. RESULTS: 46 cases were included in the analysis. 55% were male, mean age of 40 years. 95.6% were migrants. The median duration since migration from an endemic area was 10 years. Predominant nationalities were Ecuadorians (50%) and Bolivians (30.4%). Frequent locations were parenchymal (87%), subarachnoid (26.1%) and intraventricular cysts (10.9%). Serological analysis was performed in 91.3%, being 54.8% positive. Most prevalent clinical manifestations were persistent headache (60.9%), epilepsy (43.5%) and visual changes (13%). Patients were mainly treated with albendazole (76.1%), corticosteroids (67.4%), and anticonvulsionants (52.2%). 82.5% had a favorable clinical outcome. CONCLUSIONS: Most NCC cases were long-standing migrants. Few clinical differences were observed depending on the cysticerci location. The treatment was often not according to current recommendations, and no uniform criteria were followed when it came to the therapeutic regimen. NCC case management in Spain (including clinician awareness and laboratory capacity improvements) needs to be strengthened.

Subclinical atherosclerosis in low Framingham risk HIV patients.

BACKGROUND: Pathogenesis of atherosclerosis is complex, and differences between HIV-infected patients and general population cannot be completely explained by the higher prevalence of traditional cardiovascular risk factors. We aimed to analyse the association between inflammation and subclinical atherosclerosis in HIV patients with low Framingham risk score. MATERIALS AND METHODS: Case-control study. SETTING: Outpatient Infectious Diseases clinic in a university hospital. SUBJECTS: HIV-1-infected patients aged > 35 years receiving antiretroviral treatment with viral load < 50 copies/mL and Framingham risk score < 10%. EXCLUSION CRITERIA: inflammatory diseases; dyslipidaemia requiring statins; smoking > 5 cigarettes/day; diabetes; hypertension; vascular diseases. MAIN OUTCOME: subclinical atherosclerosis determined by ultrasonography: common carotid intima-media thickness greater than 0·8 mm or carotid plaque presence. Explanatory variables: ribosomal bacterial DNA (rDNA), sCD14, interleukin-6 (IL-6) and TNF-α. RESULTS: Eighty-four patients were included, 75% male, mean age 42 years and mean CD4+ cells 657 ± 215/mm3 . Median Framingham risk score was 1% at 10 years (percentile 25-75: 0·5-4%). Eighteen patients (21%) had subclinical atherosclerosis; the associated factors were older age (P = 0·001), waist-hip ratio (P = 0·01), time from HIV diagnosis (P = 0·02), rDNA (P = 0·04) and IL-6 (P = 0·01). In multivariate analysis, OR for subclinical atherosclerosis was 7 (95% CI, 1.3-40, P = 0.02) and 9 (95% CI, 1.0-85, P = 0.04) for patients older than 44 years and IL-6 > 6·6 pg/mL, respectively. CONCLUSIONS: Well-controlled HIV patients with low Framingham risk score have a high prevalence of subclinical carotid atherosclerosis, and the main risk factors are age and inflammation. These patients are not receiving primary prophylaxis for cardiovascular events according to current guidelines.
