Prevalence of diabetes mellitus in newly diagnosed pulmonary tuberculosis in Beira, Mozambique

Introduction: Data regarding the association between diabetes mellitus (DM) and tuberculosis (TB) in Africa are scarce. DM screening among TB patients in Mozambique was carried out. Methods: The study was implemented from January to August 2016 in three Urban Health Centers in Beira, Mozambique and recruited adult (>18 years) patients newly diagnosed with pulmonary TB. Results: Three hundred and one patients were enrolled (67.4%, males mean age 31.7(SD 11 years). Diabetes was diagnosed in only 3 patients (1%) and impaired glucose tolerance (IGT) in an additional 6 subjects (2%). Conclusion: A lower than expected prevalence of DM was observed, which could be explained by the lack of traditional risk factors for DM (overweight, age over 45 years, hypertension and smoking) in Mozambique

Effects of Therapy with Maraviroc on the Carotid Intima Media Thickness in HIV-1/HCV Co-infected Patients

To evaluate, in human immunodeficiency virus-hepatitis C virus co-infected patients, the impact of C-C chemokine receptor type 5 (CCR5) antagonist maravirocbased antiretroviral therapy on the carotid intima media thickness and on atheromasic plaques. Patients and Methods: In this pilot prospective study, 12 HIV-HCV co-infected patients underwent color-Doppler ultrasonography before and 48 weeks after switching to a dual therapy based on maraviroc plus protease inhibitors boosted with ritonavir. Changes of intima media thickness, inflammatory and endothelial adhesion biomarkers levels, Veterans Aging Cohort Study index and Framingham risk score were evaluated. Results: At baseline 11 (91.6%) patients showed pathological ultrasonographic findings. After 48 weeks, two patients showed an amelioration of intima media thickness. Of the remaining patients with plaques, four showed a reduction of the previously diagnosed plaque; no patients worsened. Conclusion: Our data suggest that CCR5 inhibition could reduce the development of atherosclerosis especially in the non-calcific stage and could play an important role in the blockade of atheromasic plaque progression

Limited Additive Diagnostic Impact of Isolated Gastrointestinal Involvement for the Triage of Children with Suspected COVID-19

The strategy for the selection of patients with a suspected SARS-CoV-2 infection is relevant for the organization of a children’s hospital to provide optimal separation into COVID-19 and non-COVID-19 areas and pathways. We analyzed the proportion of children with COVID-19 presenting with gastrointestinal (GI) symptoms in 137 consecutive patients admitted between January 2020 and August 2021. GI symptoms were present as follows: diarrhea in 35 patients (26%), vomiting in 16 (12%), and both of them in five (3%); the combination of fever, respiratory symptoms, and diarrhea was observed in 16 patients (12%). Of the 676 adult patients with COVID-19 admitted to our hospital in the same time interval, 62 (9.2%) had diarrhea, 30 (4.4%) had vomiting, and 11 (1.6%) had nausea; only one patient, a 38-year-old male, presented with isolated GI symptoms at the diagnosis. Although diarrhea was observed in one quarter of cases, one-half of them had the complete triad of fever, respiratory syndrome, and diarrhea, and only five had isolated diarrhea, of which two were diagnosed with a Campylobacter infection. The occurrence of either respiratory symptoms or gastrointestinal symptoms in our patients was not related to the patient age, while younger children were more likely to have a fever. Of the 137 patients, 73 (53%) could be tested for their serum level of SARS-CoV-2 specific IgG antibodies. The observed titer ranged between 0 (n = 3) and 1729 BAU/mL (median, 425 BAU/mL). Of 137 consecutive patients with COVID-19 admitted to our referral children’s hospital, only three presented with an isolated GI manifestation. It is interesting to note that this finding turned out to be fully in keeping with what was observed on adult patients with COVID-19 in our hospital. The additive diagnostic impact of gastrointestinal involvement for the triage of children with suspected COVID-19 appears limited

HCV and diabetes: Towards a 'sustained' glycaemic improvement after treatment with DAAs?

We read with interest the paper by Pavone and colleagues [1] describing the rapid reduction of fasting glucose (FG) levels in diabetic hepatitis C virus (HCV)-positive patients receiving directacting antiviral agents (DAAs). We aimed to assess if a similar decreasing trend of FG levels occurred in our study population and if it was maintained after the end of treatment (EOT). Therefore, we retrospectively evaluated 449 patients treated with DAAs at our centre (64 HIV/HCV coinfected)

The at risk child clinic (ARCC): 3 years of health activities in support of the most vulnerable children in Beira, Mozambique

The concept of “children at risk” changes worldwide according to each specific context. Africa has a large burden of overall risk factors related to childhood health and development, most of which are of an infective or social origin. The aim of this study was to report and analyze the volumes of activities of fifteen At Risk Child Clinics (ARCCs) within the Beira District (Mozambique) over a 3 year-period in order to define the health profile of children accessing such health services. We retrospectively analyzed the data from all of the children accessing one of the 15 Beira ARCCs from January 2015 to December 2017. From this, 17,657 first consultations were registered. The motivations for accessing the services were in order of relevance: HIV exposure (n. 12,300; 69.7%), other risk conditions (n. 2542; 14.4%), Moderate Acute Malnutrition (MAM) (n. 1664; 9.4%), Severe Acute Malnutrition (SAM) (n. 772; 4.4%), and TB exposure (n. 542; 3.1%). During the first consultations, 16,865 children were screened for HIV (95.5%), and 7.89% tested HIV-positive. In our three years of experience, HIV exposure was the main indication for children to access the ARCCs in Mozambique. ARCCs could represent a strategic point to better understand health demands and to monitor the quality of care provided to this vulnerable population group, however significant effort is needed to improve the quality of the data collection

Focused ultrasound to diagnose HIV-associated tuberculosis (FASH) in the extremely resource-limited setting of South Sudan: a cross-sectional study

Our cross-sectional study aimed at evaluating the diagnostic performance of Focused Assessment with Sonography for HIV-associated tuberculosis (FASH) to detect extrapulmonary tuberculosis in extremely resource-limited settings, with visceral leishmaniasis as a differential diagnosis with overlapping sonographic feature

Rapid and persistent selection of the K103N mutation as a majority quasispecies in a HIV1-patient exposed to efavirenz for three weeks: a case report and review of the literature

<p>Abstract</p> <p>Introduction</p> <p>Selection of the K103N mutation is associated with moderately reduced in vitro fitness of HIV. Strains bearing K103N in vivo tend to persist, even in the absence of additional drug pressure, as minority quasispecies, often undetectable in genotyping resistance testing assays, performed at standard conditions. Here, we report on the rapid and long lasting selection of a K103N bearing strain as the dominant quasispecies after very short exposure to efavirenz in vivo.</p> <p>Case presentation</p> <p>A 55-year-old Caucasian man was switched to efavirenz, zidovudine and lamivudine in February 2003, while on viral suppression in his first-line highly active anti-retroviral treatment regimen. One month later, he reported inconsistent adherence and his viremia level was 5700 c/mL. He did not attend further checkups until September 2005, when his viral load was 181,000 c/mL. The patient reported interrupting his medications approximately three weeks after simplification. The genotyping resistance testing assay was performed both on HIV RNA and HIV DNA from plasma, yielding an identical pattern with the isolate presence of the K103N mutation in the prevalent strain.</p> <p>Conclusion</p> <p>Persistence of the K103N mutation as a majority quasispecies may ensue after a very short exposure to efavirenz. Our case would therefore suggest that the presence of the K103N mutation should always be ruled out by genotyping resistance testing assays, even after minimal exposures to efavirenz.</p

Persistent poor clinical outcomes of people living with HIV presenting with AIDS and late for HIV diagnosis – results from the Icona cohort in Italy, 2009-2022

Background: Limited data are available on long-term outcomes in recent years for late HIV diagnosis (LD). Methods: All HIV-positive subjects enrolled in Icona Cohort in 2009-2022 starting ART within 4-months from diagnosis were included and divided into:1) pre-ART CD4 count≥350/mm3 without AIDS (non-LD), 2) pre-ART CD4 count&lt;350/mm3 without AIDS (LD-Asymptomatic), 3) with AIDS events pre-ART (LD-AIDS). Estimated probability and independent risk for mortality (all-cause and cause-specific) and treatment failure (TF) were evaluated. Results: 6,813 participants: 2,448 non-LD, 3,198 LD-Asymptomatic, and 1,167 LD-AIDS, 161 (2.4%) died after ART initiation. At survival analysis, a higher probability of all-cause mortality has been identified for LD compared to non-LD (p&lt;0.001), and within the former, for LD-AIDS over LD-Asymptomatic (p&lt;0.001). After adjusting for confounders, LD showed a higher risk of all-cause mortality (vs non-LD aHR=5.51, p&lt;0.001), and, in particular, being an AIDS presenter predicted a greater risk of all-cause (aHR=4.42, p&lt;0.001), AIDS-related (aSHR=16.86, p&lt;0.001) and not AIDS-related mortality (aSHR=1.74, p=0.022) compared to the rest of the late presenters. Among short-term survivors LD-AIDS, the long-term mortality was mediated by the lack of immune-recovery at 2-years. LD compared to non-LD, and particularly among the former, LD-AIDS over LD-Asymptomatic, showed also a greater risk of TF. Conclusions: In recent years, LD subjects, particularly AIDS-presenters, remained at a higher risk of poorer outcomes. Public health strategies for early HIV diagnosis are urgently needed to constrain the mortality gap

Impact of COVID-19 pandemic on retention in care of native and migrant people with HIV in the ICONA cohort

Background: COVID-19 pandemic challenged the UNAIDS 90-90-90 targets. How the COVID-19 pandemic affected HIV retention in care and whether it has disproportionally affected migrant people with HIV (PWH) remained to be investigated. Methods: PWH in ICONA Cohort in follow-up in each of the study periods were included: 01/09/2019-29/02/2020 (pandemic period) and 01/03/2018-31/08/2018 (historical period, as a control). Risk of temporary loss to follow-up (LTFU, defined as no data recorded for a person for one year) was analyzed by logistic regression, with migrant status as the main exposure variable. Difference in difference (DID) analysis was applied to evaluate the effect of COVID-19 pandemic in the different risk of LTFU between natives and migrants. Results: 8864 (17.1% migrants) and 8071 (16.8% migrants) PWH constituted the pandemic and the historical period population, respectively. Proportion of PWH defined as LTFU in the pandemic period was 10.5% in native and 19.6% in migrant PWH. After controlling for age, sex and geographical location of enrolling site, risk of temporary LTFU was higher for migrants than native PWH [adjusted odds ratio 1.85 (95%CI 1.54-2.22)] in pandemic period. In PWH contributing to both periods, LTFU was 9.0% (95% CI 8.3-9.8) in natives vs 17.0% (95% CI 14.7-19.4) in migrants during the pandemic. Instead, LTFU was 1.2% (95%CI 0.9, 1.5) in natives vs 2.2% (95% CI 1.3-3.1) in migrants during the historical period, with a resulting DID of 7.0% (95% CI 4.4-9.6). Conclusions: A greater proportion of LTFU in migrant PWH was observed in both periods, which remained unaltered over time. Interventions to reduce LTFU of migrants are necessary
