Background/Aims: The most effective and safe treatment protocol for Graves’ orbitopathy (GO) needs to be further assessed. The aim of the present study was to evaluate the efficacy, safety and outcome of parenteral versus parenteral and oral glucocorticoid (GC) protocols in euthyroid patients with untreated and active moderate to severe GO. Methods: This was a retrospective observational study in 140 patients comparing intravenous GC pulses only (IVGC group, 74 patients, 51 ± 11 years) with historical controls of combined oral and intravenous GC therapy (CombGC group, 66 patients, 49 ± 10 years, P = ns). IVGC therapy included infusions of 500 mg of methylprednisolone weekly for the first six weeks, followed by infusions of 250 mg weekly for the remaining six weeks (cumulative dose 4.5 g). CombGC therapy included 500 mg of methylprednisolone in 500 mL of saline solution for two alternative days, followed by oral prednisone tapering dose repeated each month for the next 5 months (cumulative dose 10.2 g). Results: The overall success of the treatment was 43/66 (65%) in the CombGC group and 37/73 (51%, P =.071) in the IVGC group. Deterioration of GO developed in four (6%) patients during CombGC therapy and in nine (12%, P =.214) patients during IVGC therapy. After 6 months, relapse of GO was observed in 10/37 (26%) in the IVGC group, whereas none of the patients in CombGC had a relapse (P <.001). There were significantly more side effects in the CombGC versus IVGC group (49/66, 74% vs 28/74, 38%, P <.001). Conclusions: Our data suggest that CombGC therapy was more efficient with significantly less relapse rate, but with more side effects in comparison to IVGC therapy. © 2020 John Wiley & Sons Ltd

Objective: Glucocorticoids (GC) are the treatment of choice for moderate-to-severe and active Graves' orbitopathy (GO), but optimal treatment is still undefined. The aim of the present study was to analyze the efficacy and tolerability of combined parenteral GC pulse therapy followed by oral GC in the interpulse period. Design: The study included 50 patients (48±10 years; 37 female) with untreated, active and moderate-to-severe GO. Patients received 500mg of methylprednisolone in 500ml of physiologic saline. Infusion was repeated after 48h and then followed by tapering doses of oral prednisone and the cycle repeated each month for the next 5 months. The cumulative dose was 10.2g. Ophthalmic assessment was performed before and 6 months after start of treatment. Side effects of GC therapy were evaluated and recorded each month. RESU LTS: GC showed the greatest effectiveness on soft tissue changes (incorporated in the CAS). Median CAS values decreased from 4.5 to 2 (p>0.001). Improvement was demonstrated in 37 patients (74%), there was no change in 13 patients (26%) and none of the patients presented with deterioration of inflammatory status. Diplopia improved in 21 patients (42%), was unchanged in 28 patients (56%) and deteriorated in 1 patient (2%). Improvement in visual acuity occurred in 36% of patients. At 6 months, 33/50 patients (66%) demonstrated overall treatment response. Response to GC therapy was influenced by CAS, TSHRAb and smoking behavior. The only independent parameter associated with positive treatment response was CAS ≥4 (p<0.001). Side effects occurred in 35/50 patients (70%) and the vast majority of them were mild to moderate. During the 6-months follow-up period, 2/33 patients (6%) had relapsing GO. Conclus Ion: With appropriate selection of patients and careful monitoring during and after treatment, combined parenteral and oral GC therapy is effective and safe.

Background: Infertility is a highly meaningful issue with potentially life-changing consequences, and its incidence has been growing worldwide. Assisted reproductive technology (ART) has made giant strides in terms of treating many infertility conditions, despite the risk of developing ovarian hyperstimulation syndrome (OHSS), a potentially life-threatening complication. Methods: This narrative review draws upon scientific articles found in the PubMed database. The search spanned the 1990–2024 period. Search strings used included “OHSS” or “ovarian hyperstimulation” and “IVF” and “GnRH” and “hCG”; 1098 results were retrieved and were ultimately narrowed down to 111 suitable sources, i.e., relevant articles dealing with the condition’s underlying dynamics, management pathways, and evidence-based criteria and guidelines, crucial both from a clinical perspective and from the standpoint of medicolegal tenability. Results: The following features constitute OHSS risk factors: young age, low body weight, and polycystic ovarian syndrome (PCOS), among others. GnRH antagonist can substantially lower the risk of severe OHSS, compared to the long protocol with a gonadotropin-releasing hormone (GnRH) agonist. However, a mild or moderate form of OHSS is also possible if the antagonist protocol is used, especially when hCG is used for the final maturation of oocytes. For women at risk of OHSS, GnRH agonist trigger and the freeze-all strategy is advisable. OHSS is one of the most frequent complications, with a 30% rate in IVF cycles. Conclusion: Providing effective care for OHSS patients begins with early diagnosis, while also evaluating for comorbidities and complications. In addition to that, we should pay more attention to the psychological component of this complication and of infertility as a whole. Compliance with guidelines and evidence-based best practices is essential for medicolegal tenability. © 2024 by the authors.

Background: Although thyroid hormones have significant effect on cardiovascular system, the impact of subtle thyroid dysfunction such as subclinical hypothyroidism (SCH) remains to be determined. We investigated coronary flow reserve (CFR) in patients with subclinical hypothyroidism. Methods: Thirty two subjects with SCH and eighteen control subjects with normal serum thyroid hormones and thyroid-stimulating hormone (TSH) levels were included in the study. TSH, free thyroxine, free triiodothyronine, glucose, insulin, HbA1c, cholesterol, triglyceride and plasma levels of C-reactive protein were measured. Coronary diastolic peak flow velocities in left anterior descending coronary artery were measured at baseline and after adenosine infusion. CFR was calculated as the ratio of hyperemic to baseline diastolic peak velocity. Results: CFR values were not significantly different between the two groups (SCH 2.76±0.35 vs controls 2.76±0.42). There was a significant correlation of CFR with waist to hip ratio, hypertension, smoking habits, markers of glucose status (glucose level, HbA1c, insulin level, HOMA IR), cholesterol, LDL-cholesterol and triglyceride levels in SCH group, whereas only cholesterol level showed significant correlation with CFR in controls. There was no correlation between CFR and thyroid hormones. Conclusions: We concluded that there is a different impact of cardiovascular risk factors on CFR in SCH patients compared to healthy control and that these two groups behave differently in the same circumstances under the same risk factors. The basis for this difference could be that the altered thyroid axis»set point« changes the sensitivity of the microvasculature in patients with SCH to known risk factors. © 2022 Sciendo.
