Detrimental Impact of Interferon-Based Regimens for Chronic Hepatitis C on Vitamin D/Parathyroid Hormone Homeostasis
Background: Both the anti-infective and anti-inflammatory properties of vitamin D, an essential hormone of calcium homeostasis, have ample support in the literature. The high rates of vitamin D deficiency among patients with chronic hepatitis C are also well known. That supplementation with vitamin D may boost sustained viral response rates in vitamin D deficient, hepatitis C virus (HCV) infected patients undergoing Interferon-alpha (IFN) treatment, on the other hand, is controversial. Surprisingly, studies considering in this latter setting what are the effects of IFN treatment (with or without vitamin D supplementation) on the other major regulator of mineral metabolism, i.e. the Parathyroid hormone (PTH), are lacking.
Aim: Evaluate the impact of interferon-based treatment against HCV (±cholecalciferol supplementation) on vitamin D and PTH
homeostasis.
Methods: A series of 40 consecutive patients received pegylated IFN plus ribavirin to treat chronic hepatitis C. At the discretion of their physician, some of them (N. = 27) received vitamin D supplementation while others did not (N. = 13). All had measured plasma 25-hydroxycholecalciferol and PTH concentrations at baseline, at completion of the 4th (TW4) and 12th treatment week (TW12) and at 24 weeks after the end of therapy (SVR24).
Results: Plasma PTH concentration increased significantly from baseline during treatment, raising to 44.8 [30.7-57.2] pg/mL at TW4 (p=0.01), 47.0 [37.1-63.2] pg/mL at TW12 (p=0.006) to return to baseline levels in the follow-up (34.5 [27.6-43.0]; p=0.16). The proportion of patients who satisfied criteria for hyperparathyroidism was higher at TW12 (N=10, 25%) than at TW4 (N=6, 15%). There was no statistical correlation between vitamin D and PTH blood levels (ρ=-0.07; p=0.65).
Conclusion: An increase in plasma PTH occurs systematically during IFN treatment of HCV patients and cannot be prevented by vitamin D supplementation
Investigating the Effects of COVID-19 Quarantine in Migraine: An Observational Cross-Sectional Study From the Italian National Headache Registry (RICe)
Background: Previous studies during SARS and Ebola pandemics have shown that quarantine is associated with several negative psychological effects, such as post-traumatic stress symptoms, confusion, and anger. These conditions may affect the course of many diseases, including migraine. Although it is possible that the quarantine measures for the current COVID-19 pandemic affect migraine burden, no information is currently available on this issue.
Aim: In this study, we aimed to: (1) explore the possible changes in migraine frequency, severity, and days with acute medication intake during quarantine period; (2) evaluate possible differences in migraine outcomes in consideration of lifestyle changes, emotions, pandemic diffusion, and COVID-19 infection.
Methods: We interviewed patients who were included in the observational Italian Headache Registry (Registro Italiano Cefalee, RICE), retrospectively collecting information on main headache features, lifestyle factors, emotions, individual infection status, and perception of COVID-19 for 2 months before (pre-quarantine) and after the beginning of the quarantine (quarantine). Inclusion criteria were: age > 18, diagnosis of migraine without aura, migraine with aura and chronic migraine, last in-person visit more than 3 months preceding the beginning of quarantine.
Results: A total of 433 migraine subjects agreed to be interviewed. We found an overall reduction in headache frequency (9.42 ± 0.43 days with headache vs. 8.28 ± 0.41) and intensity (6.57 ± 0.19 vs. 6.59 ± 0.21) during the quarantine, compared to pre-quarantine. There was a correlation between improvement and number of days of stay-at-home. When results were stratified for geographic area, we found a tendency toward worsening of headache frequency in northern Italy. Disgust regarding viral infection corresponded to a minor improvement in migraine.
Conclusions: Migraine patients showed a mild improvement of migraine features, probably attributable to resilient behavior toward pandemic distress. Disgust regarding the contagion whereas potentially favoring defensive behavior, could potentially worsen migraine. The spontaneous limitation of migraine burden during quarantine could favor patient follow-up via the use of telemedicine visits, reliable diaries, and frequent remote contacts
Joint recommendations for the diagnosis and treatment of vulvo-vaginal atrophy in women in the peri- and post-menopausal phases from the Società Italiana per la Menopausa (SIM) and the Società Italiana della Terza Età (SIGiTE)
Menopausia y Terapia Hormonal de la Menopausia Las recomendaciones 2018 de la Unidad de Endocrinología Ginecológica de Clínica Alemana de Santiago -Sociedad Italiana de la Menopausia y la Sociedad Chilena de Endocrinología Ginecológica
ABSTRACT In the last decade, the risk benefits ratio of MHT has been evaluated mainly in terms of cardiovascular risk. Present Consensus Statement is largely inspired by the Global Consensus on Menopausal Hormone Therapy in 2013 and 2016 by leading global menopause societies (The American Society for Reproductive Medicine, The Asia Pacific Menopause Federation, The Endocrine Society, The European Menopause and Andropause Society, The International Menopause Society, The International Osteoporosis Foundation and The North American Menopause Society). The aim of these Recommendations is to provide a simple and updated reference on postmenopausal MHT. The term MHT typically includes estrogen replacement therapy (ERT) and estrogen-progestogen therapy (EPT). EPT can be sequential (Seq) when progestogen is added to ERT for 10-14 days a month, or continuous combined (CC) when progestogen is administered continuously every day along with a fixed amount of estrogen. MHT also includes Tibolone and the Tissue Selective Estrogen Complex (TSEC)

Identifying metabolite markers for preterm birth in cervicovaginal fluid by magnetic resonance spectroscopy
Introduction Preterm birth (PTB) may be preceded by
changes in the vaginal microflora and metabolite profiles.
Objectives We sought to characterise the metabolite
profile of cervicovaginal fluid (CVF) of pregnant women
by 1H NMR spectroscopy, and assess their predictive value
for PTB.
Methods A pair of high-vaginal swabs was obtained from
pregnant women with no evidence of clinical infection and
grouped as follows: asymptomatic low risk (ALR) women
with no previous history of PTB, assessed at 20–22 gestational
weeks, g.w., n = 83; asymptomatic high risk
(AHR) women with a previous history of PTB, assessed at
both 20–22 g.w., n = 71, and 26–28 g.w., n = 58; and
women presenting with symptoms of preterm labor (PTL)
(SYM), assessed at 24–36 g.w., n = 65. Vaginal secretions
were dissolved in phosphate buffered saline and scanned
with a 9.4 T NMR spectrometer.
Results Six metabolites (lactate, alanine, acetate, glutamine/glutamate,
succinate and glucose) were analysed. In
all study cohorts vaginal pH correlated with lactate integral
(r = -0.62, p\0.0001). Lactate integrals were higher in
the term ALR compared to the AHR (20–22 g.w.) women
(p = 0.003). Acetate integrals were higher in the preterm
versus term women for the AHR (20–22 g.w.) (p = 0.048)
and SYM (p = 0.003) groups; and was predictive of
PTB\37 g.w. (AUC 0.78; 95 % CI 0.61–0.95), and
delivery within 2 weeks of the index assessment (AUC
0.84; 95 % CI 0.64–1) in the SYM women, whilst other
metabolites were not.
Conclusion High CVF acetate integral of women with
symptoms of PTL appears predictive of preterm delivery,
as well as delivery within 2 weeks of presentation
