Background: Condyloma acuminata (CA) are dysplastic lesions caused by human papillomavirus (HPV) infection. Condylomata acuminata are common in Human Immunodeficiency Virus- (HIV) infected individuals and have been linked to HIV transmission. Current therapeutic options for CA encompass laser, cryotherapy, imiquimod, sinecatechins, podophyllotoxin, and trichloroacetate. These topical therapies have limitations caused by significant local skin reactions, high recurrence rates, prolonged application times, and, in some cases, a supposed lower efficacy in people living with Human Immunodeficiency Virus (PLWH). Previous studies evaluated the effect in the CA treatment of tirbanibulin 1% ointment since it is a synthetic antiproliferative drug approved for the topical treatment of actinic keratoses, acting in two distinct ways: it inhibits microtubule polymerization and Src kinase signaling. Human papilloma virus can up-regulate the kinases Src and Yes, so the tirbanibulin efficient treatment of CA may be due to the suppression of Src kinase signaling. Methods: Here, we present for the first time a retrospective case series of three PLWHIV affected by CA. Case: The patients experienced variable outcomes, with complete resolution of smaller condylomas for 2 out of 3 patients. Adverse events were local and of mild to moderate severity, lasting one week or less. Conclusions: While in need of larger studies, it is possible to hypothesize tirbanibulin 1% ointment as a therapeutic alternative for people living with HIV, especially for condylomas smaller than 1 cm in size.

Background/Objectives: Extrapulmonary tuberculosis accounts for a significant portion of tuberculosis cases, presenting unique diagnostic challenges due to its heterogeneous manifestations and paucibacillary nature. This study aims to fill this gap by evaluating the diagnostic outcomes and correlations between different specimen types and test results. Methods: A retrospective analysis of electronic medical records of patients diagnosed with TB between January 2013 and December 2023 was carried out. The data extracted included patient demographics, comorbidities, TB classification, specimen types, microbiological test results, and time intervals to diagnosis. Statistical analysis was applied to compare the variables between pulmonary and extrapulmonary/disseminated TB groups. Results: Most patients were male (62.4%) and born outside of Germany (74.2%). Comorbidities, such as diabetes, cardiac disease, immunosuppressed status, and HIV, were common. Among the 194 patients, 98 had pulmonary TB, and 96 had extrapulmonary/disseminated TB. A comparison of pulmonary vs. extrapulmonary TB showed that extrapulmonary TB patients had a longer diagnostic delay (p = 0.013), more symptoms (p = 0.001), and more complications (42.7% vs. 16.3%, p < 0.001). Diagnostic challenges were evident, with multiple invasive procedures required in 43.5% of the extrapulmonary TB cases. Conclusions: This study highlights the complex clinical presentation of tuberculosis, particularly in patients with extrapulmonary and disseminated forms, who experience delayed diagnosis and more complications. These challenges in diagnosing extrapulmonary TB emphasize the need for improved diagnostic strategies and early identification, especially in high-risk populations.

Background: Anaplasma phagocytophilum is an emerging tick-borne zoonotic pathogen that typically causes mild infections, which are often successfully managed in outpatient settings. Immunosuppression associated with splenectomy is a well-documented risk factor for severe infections from pathogens such as Babesia microti and encapsulated bacteria. However, splenectomy has not previously been identified as a risk factor for severe anaplasmosis. Case Presentation: This report describes a rare case of severe anaplasmosis complicated by multiorgan failure in a patient who had undergone splenectomy several decades earlier. The clinical course was notable for pneumonia, acute respiratory distress syndrome, acute kidney injury, rhabdomyolysis, atrial fibrillation, and possible myocarditis. Despite the severity of the presentation, prompt initiation of doxycycline led to recovery, albeit with a significantly prolonged hospital stay. Conclusions: Patients with splenectomy might be more likely to develop a serious form of Anaplasmosis infection such as multiorgan failure. Clinicians in tick-borne endemic areas should be aware that non-specific symptoms can indicate anaplasmosis.

Background: Infective endocarditis (IE) is an increasingly common infection that results in significant morbidity and mortality. An important but under-analyzed subpopulation of patients with IE are those with concomitant cirrhosis. This study compared the characteristics and outcomes of patients with and without cirrhosis who were hospitalized with IE. Methods: The authors conducted a retrospective cohort study in adult patients with IE admitted at a single center from 2010 to 2020, comparing outcomes between those with and without cirrhosis at the time of admission. Results: A total of 22 patients with a history of cirrhosis and 356 patients without a history of cirrhosis were included. Over a quarter (27.3%) of those with cirrhosis experienced a decompensation event within two years of their admission for IE. Clinical features, microbiology, and direct complications from IE were largely similar between groups. There was no significant difference in IE-related mortality rates between groups, although, in an overall survival analysis, the group with cirrhosis did have a higher risk of all-cause mortality at 2 years (HR = 2.85; p = 0.012). Conclusions: This study highlights that IE in patients with cirrhosis may contribute to or trigger decompensation events. Further research is warranted to better understand morbidity outcomes in patients with cirrhosis who develop IE.

Introduction: Prognostic factor investigations for candidemia have been conducted in large-scale facilities, leading to significant evidence, including early administration of echinocandin antifungal agents and removal of central venous catheters (CVCs). In departments that provide aggressive chemotherapy or transplantation, candidiasis markers are regularly evaluated, and preemptive treatments may be initiated. However, in resource-limited facilities, candidemia detection largely relies on vital signs like fever and blood cultures. This study assessed whether evidence from large-scale facilities applies to such settings. Additionally, while prior studies indicate that early antifungal treatment is based on positive blood cultures, no established criteria exist for early administration based on fever as an indicator. Methods: This study analyzed cases of candidemia from blood cultures at Fukui General Hospital (2014–2024). Patients aged 18 or older with at least one positive blood culture for Candida species and clinical signs of infection were included, while contamination cases were excluded. The patients were categorized into survival and death groups based on 60-day survival from fever onset. The variables collected included age, gender, duration from admission to fever onset, time from fever onset to blood culture collection and antifungal treatment initiation, antifungal treatment within 72 h, serum albumin levels, history of cancer, diabetes, empiric echinocandin treatment, CVC insertion, duration of CVC insertion until fever onset, use of total parenteral nutrition, broad-spectrum antibiotic use, and sequential organ failure assessment (SOFA) score. Fever was defined as a body temperature of 38.0 °C or higher, guiding blood culture collection. Results: Of 30 candidemia cases, 29 were analyzed. Survival was significantly associated with younger age (average 73.3 ± 13.3 vs. 83.1 ± 9.1 years, p = 0.038) and antifungal treatment within 72 h of fever onset (9 vs. 3, p = 0.025). CVC use was of marginal significance (8 vs. 13, p = 0.108). There was a significant difference in the duration (in days) of CVC insertion until fever onset (median [IQR]: 15.5 [11.75–19.5] vs. 30.0 [19.0–39.0], p = 0.027). Logistic regression identified early antifungal treatment (OR = 0.065, p = 0.035) and CVC use (OR = 21.8, p = 0.024) as independent predictors of mortality. Conclusions: Early antifungal treatment within 72 h of fever onset and CVC use were independent predictors of mortality in candidemia. The importance of early antifungal treatment was reaffirmed even in smaller facilities. The impact of CVC insertion on 60-day survival cannot be readily generalized due to the limited sample size. Further research is needed to clarify the impact of fever-based antifungal initiation and CVC use on 60-day survival.

Introduction: Infectious diseases significantly impact pulmonary vascular disorders, particularly in developing countries where parasitic infections remain prevalent. These infections constitute a substantial yet frequently overlooked contributor to pulmonary hypertension. Discussion: This review examines the prevalence of parasitic lung diseases in regions where communicable infections are endemic and highlights their pathophysiological links to pulmonary hypertension. Schistosomiasis and HIV notably increase pulmonary hypertension risk in these areas. While other infectious diseases may also cause pulmonary vascular lesions, most remain insufficiently studied. The review addresses global epidemiological trends, diagnostic challenges, and recent advancements in understanding the multifaceted origins of pulmonary hypertension. Conclusion: The association between parasitic infections and pulmonary hypertension is significant, necessitating a high index of suspicion for pulmonary hypertension in patients with a history of parasitic diseases, especially in endemic regions. More research is needed to understand infection-related pulmonary hypertension mechanisms and reduce its global impact.

Background: Congenital syphilis (CS) is a transplacental infection that can lead to many long-term sequelae when not adequately treated; however, knowledge about the motor and neurological signs that newborns (NBs) with CS may present is scarce. Objective: The aim of this study was to describe the results of neurological assessment scales and general movements in NBs with CS in the first days of life. Methods: In this case-series, the Hammersmith Neonatal Neurological Examination (HNNE) and General Movements Assessment (GMA) scales were used to evaluate NBs under treatment for CS in a public Brazilian hospital in the first days of life. Results: The sample consisted of 11 NBs, with a mean birth weight of 3140.5 g, and an Apgar score at 5 min of 8.3. Among the 11 mothers, 4 (36.4%) had fewer than six prenatal visits and 5 (45.5%) did not receive any syphilis treatment. All NB (100%) were asymptomatic, with normal long bone X-rays and cerebrospinal fluid analysis. The mean score on the HNNE was 22 (suboptimal/abnormal). Eight NBs (72.7%) showed abnormalities on GMA scale (with six [54.5%] being mildly abnormal and two [18%] definitely abnormal). Only three NBs (27.3%) returned for outpatient follow-up. Conclusions: Neurological and motor evaluations were abnormal in most of the asymptomatic NBs under treatment for CS in the first days of life, when assessed through specific scales (HNNE and GMA). Most mothers did not receive adequate treatment for syphilis during pregnancy, and there were important deficiencies in post-discharge follow-up. Further studies are needed to confirm these findings and investigate whether the observed abnormalities are linked to biological or environmental factors during pregnancy.

This perspective examines the potential oncogenic mechanisms of SARS-CoV-2 through comparative analysis with established cancer-causing viruses, integrating classical virological approaches with artificial intelligence (AI)-driven analysis. The paper explores four key themes: shared oncogenic mechanisms between classical viruses and SARS-CoV-2 (including cell cycle dysregulation, inflammatory signaling, immune evasion, and metabolic reprogramming); the application of AI in understanding viral oncogenesis; the integration of neuroimaging evidence; and future research directions. The author presents novel hypotheses regarding SARS-CoV-2’s potential oncogenic mechanisms, supported by recent PET/FDG imaging studies showing persistent metabolic alterations. The manuscript emphasizes the transformative potential of combining traditional virological methods with advanced AI technologies for better understanding and preventing virus-induced cancers, while highlighting the importance of long-term monitoring of COVID-19 survivors for potential oncogenic developments.

Background/Objectives: Antimicrobial resistance (AMR) is increasingly rising due to antimicrobial overuse and misuse. In sickle cell disease (SCD) care, frequent antibiotic use drives the rapid emergence of AMR, threatening treatment options and patient lives. This systematic review synthesizes data on AMR with regard to SCD patients for the first time. Methods: A comprehensive database search for articles published in English was conducted in PubMed, Scopus, ScienceDirect, and Web of Science, with no restriction set for the year of publication. The DerSimonian–Laird method was applied to derive the pooled prevalence, while the Mantel–Haenszel method was used to calculate the pooled odds ratio. Results: A total of 18 eligible studies covering 3220 SCD patients published between 1996 and 2024 were included in this review. The common bacterial pathogens reported in the included studies were Streptococcus pneumoniae (10 studies), Staphylococcus aureus (10 studies), and Escherichia coli (4 studies). For S. aureus, the pooled resistance was highest for penicillins (ampicillin = 100%; penicillin = 93.64%; and amoxicillin = 77.82%) followed by cefuroxime (51.23%). The pooled prevalence of methicillin-resistant S. aureus (MRSA) was 19.30%. SCD patients had 2.89 and 2.47 times higher odds of being colonized or infected with penicillin-resistant and erythromycin-resistant S. aureus strains, respectively. For S. pneumoniae, resistance prevalence was highest for co-trimoxazole (81.1%), followed by penicillin (47.08%). The pooled prevalence of multidrug-resistant (MDR) S. pneumoniae isolates was 32.12%. The majority of the studies included (n = 14, 77.8%) were of moderate quality according to the modified STROBE checklist. Conclusions: This review reveals a high prevalence of AMR with regard to SCD patients. SCD patients have an increased risk of resistance to penicillin and co-trimoxazole across several bacterial pathogens. The limited geographical distribution of the included studies underscores the urgent need for expanded AMR research on the subject, especially in regions with high SCD burden.

Background: Clostridioides difficile infection (CDI) is a major cause of healthcare-associated infections globally. Understanding variations in CDI incidence and outcomes across settings, populations, and regions is important for guiding prevention strategies. Aim: The aim of this study was to determine the global epidemiology of CDI to better understand disease burden across settings and geographic regions. Methods: Relevant publications were identified through searches of major databases, including PubMed, Scopus, and Web of Science, published from 1 January 2016 through 24 July 2024. Random effects models were used to pool estimates, and 95% confidence intervals (CIs) were calculated. Results: A total of 59 studies, representing 24 countries across North America, Europe, the Asia–Pacific region, Latin America, and the Middle East, met the inclusion criteria. The incidence of CDI was highest in hospital-onset healthcare facility settings, with 5.31 cases/1000 admissions (95% CI 3.76–7.12) and 5.00 cases/10,000 patient-days (95% CI 3.96–6.15). Long-term care facilities reported 44.24 cases/10,000 patient-days (95% CI 39.57–49.17). Pediatric populations faced a greater risk, with 4.52 cases/1000 admissions (95% CI 0.55–12.17), than adults did at 2.13 (95% CI 1.69–2.61). Recurrence rates were highest for community-acquired CDI at 16.22%. The death rates for the CDI cases tracked for 30 days and of unspecified duration were 8.32% and 16.05%, respectively. Conclusions: This comprehensive review identified healthcare facilities, long-term care, pediatric populations, and North America as disproportionately burdened. This finding provides guidance on priority areas and populations for targeted prevention through antimicrobial stewardship, infection control, and surveillance.

Background: In paediatric osteoarticular infections, microorganism detection is unsuccessful in up to 55% of cases, which is not satisfactory for targeted antibiotic therapy. In particular, anaerobic fusobacteria may be underdiagnosed owing to a lack of knowledge about their properties. Methods: Based on three of our own cases and a systematic literature review regarding paediatric osteoarticular fusobacterial infections, we extracted characteristic variables and synthesised them in terms of frequencies and mean comparisons. We followed the CARE and PRISMA guidelines. Results: In our three patients with hip area infections (aged 11, 12, and 16 years; two males and one female; two with Fusobacterium nucleatum [FNU] and one with Fusobacterium necrophorum [FNE]), we only detected FNU with PCR. The patient with an FNE infection showed a septic and protracted course with six surgical interventions and secondary coxarthrosis during the follow-up. The FNU infections were milder and healed without sequelae. In the literature, there are no articles with more than 3 cases; overall, we identified 38 case reports and 3 case series with a total of 45 patients. Across all synthesised cases (73% boys), the age was 9.2 ± 4.1 years. Most patients (42%) were affected by hip joint arthritis, with or without accompanying acetabular or femoral osteomyelitis, followed by knee joint arthritis, with or without osteomyelitis, in 24% of patients. In 49% of cases, there was an ear, nose, and throat focus. Depending on the affected structure, arthrotomy (33%), arthroscopy (11%), bone (24%), and soft tissue (9%) debridement were performed, with 34% of the procedures having to be performed several times. Penicillins, metronidazole, and clindamycin were the most used antibiotics. In 32 cases (71%), the authors reported healing without sequelae. Conclusions: When samples are collected in the operating theatre for paediatric osteoarticular infections, orthopaedic surgeons should also ensure correct anaerobic sampling and consider the possibility of performing PCR. A typical child with an osteoarticular fusobacterial infection is a boy of approximately 10 years of age with an infection in the hip area and a previous infection in the ENT area.

Objectives: We aimed to analyze the landscape of viral respiratory illnesses (VRIs) in a large metropolitan area in Southern California with a focus on the COVID-19 pandemic. Methods: We conducted a retrospective cohort study within the UCLA Health System, which evaluated children aged 0–5 years who received comprehensive respiratory viral panel (cRVP) testing during August–February of 2018–2023. The patient demographics, disease severity, and clinical course were specifically compared during the pandemic. Predictors of significant VRI were determined by multivariate logistic regression. Results: A total of 1321 children underwent cRVP testing, and 753 positive subjects were identified during the study period. Rhinovirus (RV) was by far the most frequent virus detected across 5 years, even during the COVID-19 pandemic, followed by respiratory syncytial virus (RSV). Along with RSV and human metapneumovirus, RV was identified as an independent risk for significant disease and occurred irrespective of co-infection with other viruses. Conclusions: RV was the most common viral pathogen in young children, even during the height of the COVID-19 pandemic, and was an independent driver of moderate-to-severe disease, particularly in children with comorbidities. Ethnic disparities were also observed as a risk for significant disease, underscoring the need for targeted interventions and heightened clinical vigilance in pediatric populations.

Background: Interstitial lung diseases (ILDs) are a heterogeneous group of conditions that can cause fibrosis of the lung interstitium, resulting in respiratory failure and death. Patients with an ILD, particularly idiopathic pulmonary fibrosis (IPF) or connective tissue disease-associated ILDs (CTD-ILDs), are prone to develop chronic pulmonary infections such as tuberculosis (TB) and non-tuberculous mycobacterial pulmonary disease (NTM-PD). Methods: This case series examines the management of three ILD patients with a usual interstitial pneumonia (UIP) pattern and concomitant NTM-PD or TB at National Institute for Infectious Diseases “Lazzaro Spallanzani” in Rome, Italy, over three years (2019–2022). Results and Conclusions: Multi-disciplinary discussion (MDD) was crucial to define the therapeutic approach due to the increased risk of side effects and drug interactions. Our work underscored how a comprehensive diagnostic evaluation, enriched by MDD, is useful for optimizing the management and reducing drug-related adverse effects and interactions in ILD patients with cavitary lesions.

Background: Methicillin-resistant Staphylococcus aureus (MRSA) is a significant cause of healthcare-associated infections in Europe. It has become increasingly prevalent in community settings, causing skin and soft tissue infections (SSTIs). Managing community-acquired (CA) MRSA infections is challenging due to its high virulence and resistance to common antibiotics, and prevention outside the hospital setting is complex. Combination therapy has demonstrated efficacy in the treatment of severe MRSA infections. Furthermore, surgical source control is critical in treating CA-MRSA infections, involving removing the primary infection site to interrupt bacterial replication. Timeliness and a correct surgical approach are essential for successful treatment outcomes and improved quality of life. Methods: This report details the case of a 15-year-old athlete who was admitted to the intensive care unit with septic shock caused by CA-MRSA. Results: Despite initial treatment, his condition rapidly worsened. A computed tomography (CT) scan identified multiple abscesses (in the lungs, limbs, thyroid, and subscapular region) along with other complications. To achieve adequate tissue concentrations at all affected sites, a triple-targeted antimicrobial therapy was initiated and adjusted based on therapeutic drug monitoring (TDM). At the same time, daily surgical debridement was performed. The patient responded significantly to this treatment, and blood cultures eventually returned negative. Conclusions: A multidisciplinary approach involving early source control, tailored antimicrobial therapy, and, if monotherapy fails to control infection, combination therapy is advisable to treat life-threatening CA-MRSA infections.

Background/Objectives: The factors associated with post-acute sequelae of COVID-19 (PASC) are not yet fully understood in developing countries. Our objective was to investigate the relationship between food consumption and the occurrence of PASC in Brazilian elderly people. Methods: This cross-sectional study included 1322 elderly people aged 60 or over, infected with SARS-CoV-2 in 2020, living in the state of Roraima in Brazil. Using the Brazilian National Food and Nutrition Surveillance System (SISVAN, in Portuguese) tool, food consumption markers were evaluated. The persistence of post-acute sequelae of COVID-19 was assessed three months after SARS-CoV-2 infection. Poisson regression with robust variance was performed to estimate the prevalence ratio (PR) with a 95% confidence interval (95% CI). Results: Fruit consumption [PR 0.92; 95% CI: 0.85–0.99] was associated with a lower occurrence of PASC, with a significant interaction in individuals aged 60 to 69 years old, not hospitalized, and those without chronic kidney disease. In addition, the consumption of sugar-sweetened beverages [PR 1.23; 95% CI: 1.12–1.35], sandwich cookies, sweets, and treats [PR 1.12; 95% CI 1.03–1.22] was positively associated with the occurrence of PASC in the elderly people, with a significant interaction in individuals living in the capital and without hypercholesterolemia. Conclusions: Unhealthy food consumption was associated with PASC in Brazilian elderly people. An improvement in the diet quality of elderly people is necessary to minimize health complications in PASC.

Introduction: Syphilis is a sexually transmitted disease with variable symptoms, often imitating various other disorders. Syphilis progresses through primary, secondary, latent, and tertiary stages, each with distinct clinical manifestations. A sudden rise in serum hepatic enzyme levels and imaging findings that mimic sclerosing cholangitis, both associated with a positive response to targeted antibiotic treatment, may indicate a diagnosis of acute syphilitic hepatitis. Case Presentation: We report a case of early syphilis in the secondary stage, manifesting as sclerosing-cholangitis-like changes shown on ultrasonography, MR, and CT. Narrow-spectrum antibiotic therapy with procaine benzylpenicillin led to a consistent decrease in and normalization of levels of serum bilirubin and other markers of hepatic injury. Repeated sonography and MR cholangiography showed minimal residual changes in the intrahepatic biliary tree. Conclusions: Infection with Treponema pallidum is one of the rare causes of secondary cholangitis. As the incidence of syphilis is rising worldwide, it should be considered as a differential diagnosis, especially for patients with high-risk sexual behavior and for whom there are laboratory findings of cholestatic or mixed cytolytic and cholestatic hepatitis, particularly if associated with exanthema, pharyngitis, and lymphadenopathy.

Background: Schistosoma-associated pulmonary arterial hypertension (Sch-PAH), a complication of hepatosplenic schistosomiasis, is still underdiagnosed and undertreated. Sch-PAH is the third-most common cause of pulmonary arterial hypertension (PAH) in Brazil, and it is estimated that there are around 60,000 afflicted individuals. However, there is a lack of data on these patients, especially in endemic areas. Therefore, this study aimed to describe baseline demographic data, hemodynamic severity of disease, and functional impairment of Sch-PAH patients at diagnosis. Methods: For this systematic review, five databases (Embase, PubMed, SciELO, LILACS, and Cochrane) were searched to identify candidate publications reporting clinical, hemodynamic, and functional data at diagnosis of Sch-PAH patients referred to a PAH reference center in Brazil. Studies were excluded if they enrolled patients under the age of 18, the diagnosis was not confirmed by right heart catheterization (RHC), consisted of case reports, or did not report original data. Risk of bias was assessed using the Newcastle–Ottawa Scale and an adapted version for cross-sectional studies. Single-arm meta-analysis with a random-effect model was performed for each variable. Results: From 459 studies identified through systematic database searching, five studies were selected for this meta-analysis. The majority of the included patients were women (67%), New York Heart Association (NYHA) functional class III/IV (57%), mean age 49 years (95% confidence interval [95% CI], 46–52), 6 min walk distance 392 m (95% CI, 291–493), mean pulmonary arterial pressure (mPAP) 59 mmHg (95% CI, 56–61), pulmonary vascular resistance (PVR) 12 WU (95% CI, 11–13) and cardiac index (CI) 2.57 L/min/m2 (95% CI, 2.25–2.88). Conclusions: In summary, Sch-PAH has clinical characteristics similar to other forms of PAH, including connective tissue disease and idiopathic PAH. Additional studies or a unified registry would be essential for a better understanding of this relevant disease in Brazil.

Background: Despite “successful” treatment, some lung tuberculosis (TB) patients develop long-term lung impairments that includes damage to the parenchyma and reduced function, which may predispose them to diseases like pulmonary hypertension. However, this is not well understood. Therefore, we investigated whether previous or current TB patients would display elevated biomarkers of endothelial dysfunction and vascular remodeling. Methods: We performed assays for ADMA, VCAM-1, VEGF, angiopoietin-1, TBARS, NT-pro-BNP, and cardiac troponin-I. We further stratified the patients based on 1, 2, 3, and >3 previous TB episodes, and 1–5 yrs, 5–10 yrs, 10–15 yrs and >15 yrs after the last TB treatment completion. We also assessed correlations between the biomarkers and the number of previous TB episodes or the time since the completion of the last TB treatment. Results: ADMA was 70 times higher, VEGF was 2000 times higher and angiopoietin-1 was 6500 times higher than the normal range. NT-pro-BNP and cardiac troponin-I were undetected, and TBARS levels were low. There was a positive linear relationship between the number of previous TB episodes and angiopoietin-1, and between VEGF and the number of previous TB episodes. ADMA, VCAM-1 and TBARS exhibited a weak and negative linear association with the number of previous TB episodes. A negligible negative linear association was observed between the time since the completion of the last TB treatment and angiopoietin-1, VEGF and ADMA. Conclusions: Therefore, having >1 previous TB episode, despite the successful completion of TB treatment, associates with an increased risk of endothelial dysfunction/angiogenesis or vascular remodeling.
