    Abstract Background and aim: The use of systemic corticosteroids during Epstein-Barr virus (EBV)-induced infectious mononucleosis is a controversial but widespread practice. We aimed to investigate the frequency of complications in adolescents and adults with infectious mononucleosis in relation to the use of corticosteroids.
    Methods: We reviewed the clinical records of 396 patients admitted to the hospital with infectious mononucleosis (52.0% male; median age, 19 years; range, 15-87 years), with a focus on both short-term (infectious and non-infectious) and long-term (hematological malignancies) complications in relation to corticosteroid use.
    Results: A total of 155 (38.6%) patients received corticosteroids at some point during infectious mononucleosis. Corticosteroid use was significantly (P≤0.002) associated with sore throat, lymphadenopathy, leukocytosis, and with antibiotics use (mainly indicated after suspicion of tonsillar bacterial superinfection). Overall, 139/155 (89.7%) patients who were treated with corticosteroids also received antibiotics either before or during hospitalization, compared with 168/241 (69.7%) patients who did not. The frequency of short-term severe complications, either infectious (peritonsillar-parapharyngeal abscess or bacteremia) or non-infectious (splenic rupture, severe thrombocytopenia, myopericarditis, or lymphocytic meningitis) were similar in patients receiving and not receiving corticosteroids. After a median of 15 years of follow-up, only one Hodgkin's lymphoma was diagnosed, in a patient who was not treated with corticosteroids during infectious mononucleosis.
    Conclusions: The use of systemic corticosteroids during EBV-induced infectious mononucleosis is generally safe, at least with concomitant antibiotic therapy. However, this should not encourage the use of corticosteroids in this context, given that their efficacy has yet to be demonstrated.

    Abstract Background: Thrombocytopenia during Epstein-Barr virus mononucleosis is well-known; however, no recent series have investigated its frequency, associated factors, and evolution. The present study aimed to investigate platelet count characteristics in adult patients with infectious mononucleosis.
    Methods: We reviewed the clinical records of 400 patients admitted to the hospital with infectious mononucleosis (52.0% male; median age, 19 years [range, 15-87 years]), focusing on blood platelet counts, thrombocytopenia prevalence and outcomes.
    Results: Thrombocytopenia (platelet count ≤150 ×10
    Conclusions: Transient thrombocytopenia is common during infectious mononucleosis in adult patients. Patients with thrombocytopenia have distinct clinical and biological features; it is typically mild during infectious mononucleosis. Cases of severe thrombocytopenia are rare and were not associated with hemorrhagic complications in this series.

    Abstract Continuous glucose monitoring systems (CGM) are a very useful tool to understand the behaviour of glucose in different situations and populations. Despite the widespread use of CGM systems in both clinical practice and research, our understanding of the reproducibility of CGM data remains limited. The present work examines the reproducibility of the results provided by a CGM system in a random sample of a free-living adult population, from a functional data analysis approach. Functional intraclass correlation coefficients (ICCs) and their 95% confidence intervals (CI) were calculated to assess the reproducibility of CGM results in 581 individuals. 62% were females 581 participants (62% women) mean age 48 years (range 18-87) were included, 12% had previously been diagnosed with diabetes. The inter-day reproducibility of the CGM results was greater for subjects with diabetes (ICC 0.46 [CI 0.39-0.55]) than for normoglycaemic subjects (ICC 0.30 [CI 0.27-0.33]); the value for prediabetic subjects was intermediate (ICC 0.37 [CI 0.31-0.42]). For normoglycaemic subjects, inter-day reproducibility was poorer among the younger (ICC 0.26 [CI 0.21-0.30]) than the older subjects (ICC 0.39 [CI 0.32-0.45]). Inter-day reproducibility was poorest among normoglycaemic subjects, especially younger normoglycaemic subjects, suggesting the need to monitor some patient groups more often than others.

    Abstract Background: Hypertriglyceridemia can occur in lymphoproliferative disorders. Infectious mononucleosis is a self-limiting, benign lymphoproliferative disorder. This study aimed to investigate the serum triglyceride concentrations and their change over time in patients with infectious mononucleosis.
    Methods: We evaluated an adult patient with severe hypertriglyceridemia (>1000 mg/dL) during infectious mononucleosis and reviewed the records of 360 patients admitted to our hospital because of infectious mononucleosis (median age, 19 years; range, 15-87 years; 51.4% male). We compared the serum triglyceride concentrations with those of a control sample from the general population (n=75). A second triglyceride measurement, obtained during convalescence (median of 30 days after the initial determination), was available for 160 patients.
    Results: The triglyceride concentrations in the acute phase (median: 156 mg/dL) were significantly higher than those of the controls (median, 76 mg/dL; P<0.001). A total of 194 (53.9%) patients presented with hypertriglyceridemia (>150 mg/dL), which was more common in the patients older than 30 years than in the younger patients (78.6% vs. 50.6%; P<0.001). A significant correlation (P<0.005) was observed between the triglyceride levels and white blood cell counts, total cholesterol levels, and liver damage markers. The triglyceride concentrations decreased during convalescence (P<0.001) and were lower than the initial measurement in 83.7% of the cases. Conversely, the total cholesterol concentrations during the acute phase were lower than those of the controls and increased during convalescence (P<0.001).
    Conclusions: Patients with severe infectious mononucleosis frequently show mild, transient hypertriglyceridemia. Further studies are needed to elucidate the mechanisms underlying this finding.

    Abstract Background: During the last decades, the frequency of multiple sclerosis (MS) is increasing worldwide. Nevertheless, the higher sensibility of the new diagnostic criteria obscures the comparison between studies performed in different decades.
    Methods: The evolution of the frequency of MS in Santiago de Compostela (North-West of Spain) between 2003 and 2015 was analyzed using Poisson regression. The diagnosis was confirmed according to Poser criteria. Several sources were consulted for case ascertainment: databases from the MS Unit, the Infusion Center, and the Departments of Neurology, Pharmacy, Pediatric Neurology and Codification of the public Hospital of Santiago, private hospitals, neurologists with private activity, general practitioners, and associations of patients.
    Results: In 12 years, the prevalence increased from 68 to 143 cases/100,000 inhabitants, from 83 to 176 in females; and from 49 to 106 in males (p <0.0001, 0.0001, and 0.0002 respectively). The incidence rise was not significant (from 5 to 8 cases/ 100,000 inhabitants/ year (p=0.4243). The mean age of the population growth 5.7 years (p=0.008). The changes in female: male ratio (12.9%), in the age at the first symptom (2.2 years), and the diagnosis delay (0.12 years) did not achieve significance (p=0.7750, 0.1606, 0.8581).
    Conclusion: The prevalence of MS doubled in 12 years whilst the difference in incidence was lower and not significant. The disproportion in the growth of both parameters, as well as the higher mean age in the last study, suggest a longer survival of patients with MS.

    Abstract Background: Liver involvement during infectious mononucleosis is common, but jaundice is considered rare. This study aimed to investigate serum bilirubin concentrations in patients with infectious mononucleosis and immune abnormalities associated with jaundice.
    Methods: We report on an adult patient with monoclonal B lymphocytosis and IgM-lambda gammopathy who developed a severe icteric hepatitis during infectious mononucleosis. We then reviewed the clinical records of 389 patients admitted to the hospital with infectious mononucleosis between 1995 and 2018 (51.7% male patients; median age, 19 years; range, 15-87 years) with focus on liver abnormalities and associated factors.
    Results: Fifty-nine patients (15.1%) had serum bilirubin concentrations between 1.5 and 3 mg/dL, and 47 patients (12.0%) had serum bilirubin >3 mg/dL. Patients with increased bilirubin concentrations had a distinct clinical presentation, with more frequent abdominal pain, nausea and vomiting, and less frequent sore throat than patients with normal bilirubin. Age and sex were not significantly different for the patients with increased and normal serum bilirubin concentrations. The patients with increased serum bilirubin concentrations showed higher levels of immune activation markers than the patients with normal bilirubin, including blood lymphocyte counts, serum IgM, and β
    Conclusions: Transient hyperbilirubinemia is common during severe (in-hospital) infectious mononucleosis in adult patients. Patients with hyperbilirubinemia have less frequent pharyngitis symptoms and more frequent abdominal symptoms. Hyperbilirubinemia during infectious mononucleosis is associated with immune activation markers.

    Abstract To date, no model has jointly encompassed clinical, inflammatory, and redox markers with the risk of a non-dipper blood pressure (BP) profile. We aimed to evaluate the correlation between these features and the main twenty-four-hour ambulatory blood pressure monitoring (24-h ABPM) indices, as well as to establish a multivariate model including inflammatory, redox, and clinical markers for the prediction of a non-dipper BP profile. This was an observational study that included hypertensive patients older than 18 years. We enrolled 247 hypertensive patients (56% women) with a median age of 56 years. The results showed that higher levels of fibrinogen, tissue polypeptide-specific antigen, beta-2-microglobulin, thiobarbituric acid reactive substances, and copper/zinc ratio were associated with a higher risk of a non-dipper BP profile. Nocturnal systolic BP dipping showed a negative correlation with beta-globulin, beta-2-microglobulin, and gamma-globulin levels, whereas nocturnal diastolic BP dipping was positively correlated with alpha-2-globulin levels, and negatively correlated with gamma-globulin and copper levels. We found a correlation between nocturnal pulse pressure and beta-2-microglobulin and vitamin E levels, whereas the day-to-night pulse pressure gradient was correlated with zinc levels. Twenty-four-hour ABPM indices could exhibit singular inflammatory and redox patterns with implications that are still poorly understood. Some inflammatory and redox markers could be associated with the risk of a non-dipper BP profile.
