USEFULNESS OF AN AD HOC QUESTIONNAIRE (ACRO-CQ) FOR THE SYSTEMATIC ASSESSMENT OF ACROMEGALY COMORBIDITIES AT DIAGNOSIS AND THEIR MANAGEMENT AT FOLLOW-UP

Purpose: To determine the validity of a self-administered questionnaire (Acro-CQ) developed to systematically assess the presence, type and time of onset of acromegaly comorbidities. Methods: This is a cross-sectional study; 105 acromegaly patients and 147 controls with other types of pituitary adenoma, referred to a specialized Italian Center, autonomously compiled Acro-CQ in an outpatient clinical setting. To test its reliability in a different setting, Acro-CQ was administered via mail to 78 patients with acromegaly and 100 with other pituitary adenomas, referred to a specialized US Center. Data obtained from questionnaires in both settings were compared with medical records (gold standard). Results: Demographics of patients and controls from both countries were similar. In both settings, >95 % of the questionnaires were completely filled; only one item was missed in the others. Concordance with medical record was excellent (k > 0.85) for most of the items, independently from the way of administration, patient age, gender and nationality, pituitary adenoma type and disease activity. Conclusions: Acro-CQ is an inexpensive, highly accepted from patients and reliable tool recommended to expedite systematic collection of relevant clinical data in acromegaly at diagnosis, to be replicated at follow-ups. This tool may guide a targeted, cost-effective management of complications. Moreover, it could be applied to retrieve data for survey studies in both acromegaly and other pituitary adenomas, as information is easily and rapidly accessible for statistical analysis

Le neoplasie associate a feocromocitoma/paraganglioma in quadri SDHx positivi o negativi: adenomi ipofisari, tumori stromali gastro-intestinali e tumori renali

SommarioI feocromocitomi e paragangliomi (PPGL) sono geneticamente determinati in almeno il 30% dei casi. Le mutazioni identificate più recentemente, in particolare quelle dei geni SDHx, possono favorire, seppur raramente, anche l'insorgenza di tumori stromali gastro-intestinali, carcinomi renali e adenomi ipofisari. Pertanto, in caso di diagnosi di una delle suddette neoplasie, il clinico dovrebbe valutare l'anamnesi personale e familiare alla ricerca di eventuali PPGL, così come in pazienti con PPGL associato a mutazione di SDHx, TMEM127 e MAX si dovrebbe indagare la presenza di neoplasie potenzialmente correlate

Copeptin adaptive response to SGLT2 inhibitors in patients with type 2 diabetes mellitus: The GliRACo study

IntroductionIn type 2 diabetes mellitus (T2DM), the antidiuretic system participates in the adaptation to osmotic diuresis further increasing urinary osmolality by reducing the electrolyte-free water clearance. Sodium glucose co-transporter type 2 inhibitors (SGLT2i) emphasize this mechanism, promoting persistent glycosuria and natriuresis, but also induce a greater reduction of interstitial fluids than traditional diuretics. The preservation of osmotic homeostasis is the main task of the antidiuretic system and, in turn, intracellular dehydration the main drive to vasopressin (AVP) secretion. Copeptin is a stable fragment of the AVP precursor co-secreted with AVP in an equimolar amount.AimTo investigate the copeptin adaptive response to SGLT2i, as well as the induced changes in body fluid distribution in T2DM patients.MethodsThe GliRACo study was a prospective, multicenter, observational research. Twenty-six consecutive adult patients with T2DM were recruited and randomly assigned to empagliflozin or dapagliflozin treatment. Copeptin, plasma renin activity, aldosterone and natriuretic peptides were evaluated at baseline (T0) and then 30 (T30) and 90 days (T90) after SGLT2i starting. Bioelectrical impedance vector analysis (BIVA) and ambulatory blood pressure monitoring were performed at T0 and T90.ResultsAmong endocrine biomarkers, only copeptin increased at T30, showing subsequent stability (7.5 pmol/L at T0, 9.8 pmol/L at T30, 9.5 pmol/L at T90; p = 0.001). BIVA recorded an overall tendency to dehydration at T90 with a stable proportion between extra- and intracellular fluid volumes. Twelve patients (46.1%) had a BIVA overhydration pattern at baseline and 7 of them (58.3%) resolved this condition at T90. Total body water content, extra and intracellular fluid changes were significantly affected by the underlying overhydration condition (p < 0.001), while copeptin did not.ConclusionIn patients with T2DM, SGLT2i promote the release of AVP, thus compensating for persistent osmotic diuresis. This mainly occurs because of a proportional dehydration process between intra and extracellular fluid (i.e., intracellular dehydration rather than extracellular dehydration). The extent of fluid reduction, but not the copeptin response, is affected by the patient’s baseline volume conditions.Clinical trial registrationClinicaltrials.gov, identifier NCT03917758

Acromegaly is associated with increased cancer risk: A survey in Italy

It is debated if acromegalic patients have an increased risk to develop malignancies. The aim of the present study was to assess the standardized incidence ratios (SIRs) of different types of cancer in acromegaly on a large series of acromegalic patients managed in the somatostatin analogs era. It was evaluated the incidence of cancer in an Italian nationwide multicenter cohort study of 1512 acromegalic patients, 624 men and 888 women, mean age at diagnosis 45 \uc2\ub1 13 years, followed up for a mean of 10 years (12573 person-years) in respect to the general Italian population. Cancer was diagnosed in 124 patients, 72 women and 52 men. The SIRs for all cancers was significantly increased compared to the general Italian population (expected: 88, SIR 1.41; 95% CI, 1.18-1.68, P < 0.001). In the whole series, we found a significantly increased incidence of colorectal cancer (SIR 1.67; 95% CI, 1.07-2.58, P = 0.022), kidney cancer (SIR 2.87; 95% CI, 1.55-5.34, P < 0.001) and thyroid cancer (SIR 3.99; 95% CI, 2.32-6.87, P < 0.001). The exclusion of 11 cancers occurring before diagnosis of acromegaly (all in women) did not change remarkably the study outcome. In multivariate analysis, the factors significantly associated with an increased risk of malignancy were age and family history of cancer, with a non-significant trend for the estimated duration of acromegaly before diagnosis. In conclusion, we found evidence that acromegaly in Italy is associated with a moderate increase in cancer risk

How future surgery will benefit from SARS-COV-2-related measures: a SPIGC survey conveying the perspective of Italian surgeons

COVID-19 negatively affected surgical activity, but the potential benefits resulting from adopted measures remain unclear. The aim of this study was to evaluate the change in surgical activity and potential benefit from COVID-19 measures in perspective of Italian surgeons on behalf of SPIGC. A nationwide online survey on surgical practice before, during, and after COVID-19 pandemic was conducted in March-April 2022 (NCT:05323851). Effects of COVID-19 hospital-related measures on surgical patients' management and personal professional development across surgical specialties were explored. Data on demographics, pre-operative/peri-operative/post-operative management, and professional development were collected. Outcomes were matched with the corresponding volume. Four hundred and seventy-three respondents were included in final analysis across 14 surgical specialties. Since SARS-CoV-2 pandemic, application of telematic consultations (4.1% vs. 21.6%; p < 0.0001) and diagnostic evaluations (16.4% vs. 42.2%; p < 0.0001) increased. Elective surgical activities significantly reduced and surgeons opted more frequently for conservative management with a possible indication for elective (26.3% vs. 35.7%; p < 0.0001) or urgent (20.4% vs. 38.5%; p < 0.0001) surgery. All new COVID-related measures are perceived to be maintained in the future. Surgeons' personal education online increased from 12.6% (pre-COVID) to 86.6% (post-COVID; p < 0.0001). Online educational activities are considered a beneficial effect from COVID pandemic (56.4%). COVID-19 had a great impact on surgical specialties, with significant reduction of operation volume. However, some forced changes turned out to be benefits. Isolation measures pushed the use of telemedicine and telemetric devices for outpatient practice and favored communication for educational purposes and surgeon-patient/family communication. From the Italian surgeons' perspective, COVID-related measures will continue to influence future surgical clinical practice

Isolated Third Cranial Nerve Palsy Associated with Sudden Worsening of Hypotonic Hyponatremia Secondary to Ischemic Pituitary Apoplexy

Pituitary apoplexy (PA) is a rare medical emergency. The sudden pressure increase in the sella turcica may determine compression on the surrounding structures determining the classical symptomatology associated, especially visual field impairment and/or ocular palsies and hypopituitarism; hypotonic hyponatremia may occur too, even if it is not common. Although already described in the literature, cases of isolated III cranial nerve palsies are extremely rare events. We report the case of a mid-60-year-old man with a known pituitary adenoma accessing the Emergency Department (ED) for worsening headaches unresponsive to analgesics, with a morphological picture consistent with ischemic PA, despite no dimensional increase of the pituitary lesion; upon ED access, a mild paucisymptomatic hyponatremia was also observed. Dexamethasone and mannitol were empirically introduced upon neurosurgical indication and tramadol and ketorolac were promptly administered as well, but without benefit. In the next days, a severe hypotonic hyponatremia was evidenced and a clear left III cranial nerve palsy developed, but no clear signs of cerebral bleeding or ischemia, nor a significant compression on the homolateral cavernous sinus, were observed. Upon ruling out other possible causes, a likely diagnosis of syndrome of inappropriate antidiuresis (SIAD) was made, confirmed by the quick response to fluid restriction. Overall, the sudden fall in tonicity plasma levels seemed to contribute to the exacerbation of the neurological deficit since the normalization of sodium levels was associated with a rapid and complete reversion of the III cranial nerve palsy
