Reduced early response to SARS-CoV2 vaccination in people with type 1 and type 2 diabetes, a 6 months follow-up study: The CoVaDiab study I.

INTRODUCTION: Diabetes mellitus worsens the prognosis of SARS-CoV-2 infection, and vaccination has been the major tool for reducing the risk of hospitalisation, and mortality. The primary aim of this study was to evaluate the response to the SARS-CoV-2 vaccine in subjects with diabetes and controls. Differences between type 1 (T1D) and type 2 (T2D) diabetes and clinical determinants of vaccination response were also evaluated. METHODS: 128 subjects with diabetes (60 with T1D and 62 with T2D) and 202 subjects acting as controls who completed a full vaccination cycle with two doses of mRNA vaccine were enroled. People with previous SARS-CoV-2 infection were excluded. Antibodies (Ab) directed against the spike protein of the SARS-CoV-2 were evaluated at one and 6 months after vaccination. RESULTS: In the whole cohort, the Ab level was higher among women than in men (p = 0.011) and negatively correlated with age (rho = -0.155, p = 0.005). Subjects with diabetes showed decreased levels of Ab after one month compared to controls (1217[747-1887]BAU/mL vs. 1477[942-2556]BAU/mL, p = 0.002), even after correction for age and gender (p = 0.002). No difference was found between subjects with T1D and T2D. After 6 months, antibody levels significantly decreased in people with and without diabetes, with no differences between groups, although some subjects were lost at follow-up. In subjects with diabetes, only a significant correlation was found between Ab level and renal function (rho 0.190, p = 0.042). CONCLUSIONS: Both T1D and T2D are associated with a reduced early response to vaccination. The serum concentration of Ab significantly reduced over time in both groups, highlighting the relevance of vaccination boosters independently of the presence of diabetes.

Contemporary prescriptions pattern of different dose levonorgestrel-releasing intrauterine systems in an Italian service for family planning.

OBJECTIVE: Current research informations fail to adequately inform about when levonorgestrel-releasing intrauterine system (LNG-IUS) 52 mg is used instead of other lower dose LNG-IUSs (13.5 and 19.5 mg) and other long-acting reversible contraceptives (LARCs) in clinical practice. METHODS: A retrospective cohort study was performed in a third-level Service for Family Planning of Modena University hospital about all the first modern contraceptives prescriptions in the whole year 2019 performed by the same group of physicians. All women included underwent a detailed transvaginal ultrasound (TVUS) at prescription and a second evaluation within 3 months when they were still using the prescribed method. RESULTS: To 69/160 (43.1%) women a short-acting reversible contraceptive (SARC), while to 91/160 (56.9%) a LARC was prescribed. Women with a LARC prescription were older than them with a short-acting (SARC) (p < .0001). Women with LNG-IUS 52 mg prescription were significantly the oldest (42.9 ± 5.3), while those with intrauterine copper device and lower dose LNG-IUS were of similar age (36.5 ± 7.3 and 34.9 ± 2.3), significantly lower (p < .005). Women with implant prescription had the same age as SARC, being the youngest (30.7 ± 8.9 and 31.0 ± 9.5) (p < .0001). Women with LNG-IUS 52 mg prescription mg presented with bigger uterine volume (p = .001). In multivariate analyses, the LNG-IUS 52 mg prescription was significantly linked only to age (OR 1.24; 95% CI 1.11-1.37, p < .0001) and presence of adenomyosis (OR 4.56; 95% CI 1.45-14.33, p = .009). CONCLUSIONS: The use of LNG-IUS 52 mg instead of other LARCs is preferred for older women, with uteri of increased volume due to adenomyosis, suggesting a possible differential use of available LNG-IUSs in the contemporary clinical practice.

Drospirenone 4 mg-only pill (DOP) in 24+4 regimen: a new option for oral contraception.

INTRODUCTION: The use of progestin-only pills (POPs) is still relatively infrequent, mainly for their unpredictable effect on menstrual bleeding. A new POP consisting of 4 mg drospirenone (DRSP) for 24 days plus 4-day hormone-free interval has been developed to address this need. DRSP is a potent progestin analogue of spironolactone, with antiandrogenic and antimineralocorticoid properties. AREAS COVERED: This is a narrative review of the available data on the pharmacotherapy of the new DRSP-only pill. The research includes aspects of pharmacokinetics/pharmacodynamics of the compound: the main focus is on the clinical effects of DRSP-only pill in terms of contraceptive efficacy, haemostatic effect, safety, tolerability and bleeding patterns. EXPERT OPINION: The DRSP-only pill presents a similar Pearl Index to that of common combined hormonal contraceptives: it is a POP with a better bleeding profile than traditional POPs (higher rates of scheduled bleedings and much lower rates of unscheduled intracyclic bleeding/spotting) which could increase its acceptability and the panorama of possible users. For these reasons, DRSP-only pill represents a real step forward in oral contraception with only progestins, even if the bleeding patterns during its use are still different to oestrogen-containing products (i.e. lower rates of scheduled bleedings and higher rate of amenorrhea).
