RESUMO

In vitro maturation (IVM) of oocytes represents an assisted reproductive technique that involves the minimal or absence of ovarian stimulation and is beneficial to specific groups of patients. It is based on the collection of immature cumulus-oocyte complexes (COCs) from antral follicles, which are cultured in vitro until they reach the metaphase II (MII) stage. Once maturation is completed, IVM oocytes are normally fertilized, as during a conventional IVF protocol. On the other hand, ovarian rejuvenation through the intraovarian platelet-rich plasma (PRP) injection represents an innovative procedure intended to restore ovarian fertility and development, and it is used to enhance ovarian stimulation outcomes. Here, we report a case of a 47-year-old woman who underwent an assisted reproductive technology cycle (ART) with PRP injection and IVM, which resulted in a successful pregnancy.

RESUMO

In vitro maturation of oocytes (IVM) represents an assisted reproductive technique that involves the minimal or absence of ovarian stimulation and is beneficial to specific groups of patients. These may include women with polycystic ovarian syndrome and/or patients who need a fertility preservation option before undergoing gonadotoxic treatment. However, when IVM is applied in cases where it is not recommended, it can be considered as an add-on technique, as described by the ESHRE Guideline Group on Female Fertility Preservation. Interestingly, IVM has not been proven yet to be as effective as conventional IVF in the laboratory, in terms of clinical pregnancy and live birth rates, while concerns have been raised for its long-term safety. As a result, both safety and efficacy of IVM remain still questionable and additional data are needed to draw conclusions.

RESUMO

Poland syndrome is a congenital anatomical anomaly, characterised by partial or total aplasia of one side of the body causing abnormalities affecting the chest, shoulder, and upper limb. The exact mechanism that leads to this syndrome is unknown, but an abnormality in the vasculature formation or interruption of the blood supply of the subscapular artery and its branches early in development may be the main cause. Depending on the underlying mechanism, the syndrome has several expressions with some hardly being detectable and others not even being compatible with life. Here, we present a case of pregnancy from an assisted reproductive technology (ART) cycle with in vitro maturation (IVM) and rescue intra cytoplasmic sperm injection (ICSI), which resulted in the in-utero death of the foetus. The subsequent necropsy revealed a variation of Poland syndrome.

RESUMO

OBJECTIVES: A reduced adrenal reserve-associated cortisol production relative to the enhanced needs of chronic inflammation (disproportion principle) has been observed in rheumatoid arthritis (RA). We examined the possible clinical value of diurnal cortisol measurements in active RA on treatment response prediction. METHODS: Diurnal cortisol production (measured at: 08-12:00/18:00-22:00) was assessed by electrochemiluminescence immunoassay in 28 consecutive patients with moderately/highly active RA, as well as 3 and 6 months after treatment initiation or/escalation. Twenty-eight COVID-19 patients and 28 age-matched healthy individuals (HC) served as controls. RESULTS: Saliva diurnal cortisol production in patients with RA was similar to that of HC, despite 12-fold higher serum C reactive protein (CRP) levels, and lower than COVID-19 patients (area under the curve: RA: 87.0±37.6 vs COVID-19: 146.7±14.3, p<0.001), having similarly high CRP. Moreover, a disturbed circadian cortisol rhythm at baseline was evident in 15 of 28 of patients with RA vs 4 of 28 and 20 of 28 of HC and COVID-19 patients, respectively. Treatment-induced minimal disease activity (MDA) at 6 months was achieved by 16 of 28 patients. Despite comparable demographics and clinical characteristics at baseline, non-MDA patients had lower baseline morning cortisol and higher adrenocorticotropic hormone (ACTH) levels compared with patients on MDA (cortisol: 10.9±4.0 vs 18.4±8.2 nmol/L, respectively, p=0.005 and ACTH: 4.8±3.3 vs 2.4±0.4 pmol/L, respectively, p=0.047). Baseline morning cortisol <13.9 nmol/L predicted non-MDA at 6 months (75% sensitivity, 92% specificity, p=0.006). Prospective measurements revealed that individualised diurnal cortisol production remained largely unchanged from baseline to 3 and 6 months. CONCLUSIONS: An impaired adrenal reserve is present in patients with RA. Further studies to confirm that assessment of diurnal cortisol production may be useful in guiding treatment decisions and/or predicting treatment response in RA are warranted. TRIAL REGISTRATION NUMBER: NCT05671627.

RESUMO

OBJECTIVES: To examine adrenal cortex reserve in patients with rheumatic and musculoskeletal diseases (RMD) who relapse upon tapering of low glucocorticoid dose, despite concomitant treatment with disease-modifying anti-rheumatic drugs (DMARDs). METHODS: A morning standard dose of 250 mcg tetracosactide (Synacthen test) was given in 25 consecutive patients (13 rheumatoid arthritis, 2 psoriatic arthritis, 5 systemic lupus erythematosus, 2 dermatomyositis, 1 systemic sclerosis, 2 temporal arteritis) at the time of relapse upon small reductions (1-2 mg daily) of low prednisolone dose (<7.5 mg daily), while being on stable concomitant treatment with methotrexate, leflunomide, hydroxychloroquine, azathioprine, mycophenolate, tofacitinib, belimumab, anti-TNF, anti-IL-6 or anti-IL-1 regimens (n=14; 3; 9; 1; 2; 1; 1; 5; 2; 1, respectively). Sex-matched apparently healthy individuals (n=45) served as controls. RESULTS: Baseline cortisol levels and time-integrated cortisol response to tetracosactide were lower in patients than controls (12.01±4.47 vs. 15.63±4.16 mcg/dl, p=0.001, and 1050±286 vs. 1284±182, p<0.001, respectively). No significant associations were observed between the cortisol response to tetracosactide and age, duration of disease or glucocorticoid treatment. An abnormal Synacthen test, indicative of adrenal insufficiency, presumably secondary to chronic glucocorticoid administration, was noted in 5/25 patients. The remaining 20 patients (80%) had normal Synacthen test demonstrating, however, lower cortisol response than controls, independently of age (ß-coefficient=-0.373, p=0.033). CONCLUSIONS: Patients with RMD in remission under DMARDs who relapse upon concomitant low glucocorticoid dose tapering should be tested for iatrogenic adrenal insufficiency. Whether a marginally normal Synacthen test should discourage further attempts to withdraw glucocorticoid treatment in these patients warrants further investigation.

RESUMO

RESEARCH QUESTION: Are there any differences in viability, spindle abnormalities and mitochondrial and other organelle structures amongst embryos biopsied on day 3 versus day 5 before and after vitrification? DESIGN: A total of 240 day 3 biopsied embryos that developed to blastocysts but were rejected for transfer following preimplantation genetic testing for monogenic/single gene defects (PGT-M) (n = 115) or for aneuploidies (PGT-A) (n = 125) were divided into two groups: (i) 120 blastocysts treated for viability, spindle/chromosome configuration (SCC) analysis and transmission electron microscopy (TEM) analysis (fresh n = 20, n = 20, n = 20 and following vitrification/warming n = 20, n = 20, n = 20); (ii) 120 embryos were re-biopsied at the blastocyst stage and treated for viability, SCC and TEM analysis (fresh n = 20, n = 20, n = 20 and following vitrification/warming n = 20, n = 20, n = 20). Also, 60 vitrified blastocysts biopsied only on day 5 that were rejected for transfer following PGT-M (n = 6) or PGT-A (n = 54) were treated following warming for viability (n = 20), SCC (n = 20) and TEM analysis (n = 20). RESULTS: No differences were observed in SCC and ultrastructure between embryos biopsied on day 5 and day 3 but following vitrification higher numbers of abnormal spindles, distension of mitochondria, multivesicular bodies, lipofuscin droplets, altered cell junctions and occasionally excessive accumulation of glycogen granules were evident. The fresh day 3 biopsied group also had a lower incidence of damaged (propidium iodide-stained) cells compared with the fresh day 3+5 (P = 0.02) and the vitrified day 5 (P = 0.001) biopsied groups. CONCLUSIONS: Biopsies on day 5 and day 3 do not adversely affect embryo viability, SCC or ultrastructure, although following vitrification minimal embryo quality-dependent increases in spindle abnormalities and cell damage are observed.

RESUMO

PURPOSE: The beneficial effect of glucocorticoids in coronavirus disease (COVID-19) is established, but whether adrenal cortisol secretion is impaired in COVID-19 is not fully elucidated. In this case-control study, we investigated the diurnal free bioavailable salivary cortisol secretion in COVID-19 patients. METHODS: Fifty-two consecutive COVID-19 patients-before dexamethasone treatment in cases required-recruited between April 15 to June 15, 2021, (NCT04988269) at Laikon Athens University-Hospital, and 33 healthy age- and sex-matched controls were included. Diurnal salivary cortisol (8 a.m., 12, 6, and 10 p.m.), plasma adrenocorticotropin (ACTH) and aldosterone, and serum interleukin-6 (IL-6) and C-reactive protein (CRP) levels were assessed. Diurnal salivary dehydroepiandrosterone (DHEA) and IL-6 were also assessed in subgroups of patients. RESULTS: Median CRP and IL-6 measurements were about sixfold higher in patients than controls (both p < 0.001) Morning salivary cortisol levels did not differ between the two groups, but patients exhibited higher median levels of evening and nocturnal salivary cortisol compared to controls [0.391 (0.054, 0663) vs. 0.081 (0.054, 0.243) µg/dl, p < 0.001 and 0.183 (0.090, 0.834) vs. 0.054 (0.054, 0.332) µg/dl, p < 0.001, respectively], resulting in higher time-integrated area under the curve (AUC) (4.81 ± 2.46 vs. 2.75 ± 0.810, respectively, p < 0.001). Circulating ACTH, DHEA, and aldosterone levels were similar in patients and controls. Serum IL-6, but not ACTH levels, was strongly correlated with nocturnal cortisol salivary levels (ρ = 0.555, p < 0.001) in patients. CONCLUSIONS: Increased evening and nocturnal but not morning cortisol secretion may occur in even clinically mild COVID-19. In the context of acute viral infection (COVID-19), IL-6 may partially replace ACTH as a stimulus of the glucocorticoid-secreting adrenal zona-fasciculata without influencing the secretion of DHEA and aldosterone.

RESUMO

BACKGROUND: Iatrogenic adrenal insufficiency (AI) secondary to long-term treatment with exogenous glucocorticoids (GC) is common in patients with systematic rheumatic diseases, including rheumatoid arthritis (RA). Moreover, a proportion of these patients is always in need of even small doses of glucocorticoids to maintain clinical remission, despite concomitant treatment with conventional and biologic disease-modifying drugs. METHODS: We conducted a literature review up to December 2020 on (a) the incidence of AI in both long-term GC-treated and GC-treatment naïve RA patients; (b) the potential effects of increased levels of circulating proinflammatory cytokines, as well as of chronic stress, in adrenocortical function in RA; (c) the circadian cortisol rhythm in RA; and (d) established and evolving methods of assessment of adrenocortical function. RESULTS: Up to 48% of RA patients develop glucocorticoid-induced AI; however, predictors are not established, while adrenocortical dysfunction may also occur in GC-treatment naïve RA patients. Experimental and clinical data have suggested that inadequate production of endogenous cortisol relative to enhanced clinical needs associated with the systemic inflammatory response, coined as the 'disproportion principle', may operate in RA. Although the underlying mechanisms are unknown, both proinflammatory cytokines and chronic stress may contribute the most in the adrenals hyporesponsiveness and the target tissue glucocorticoid resistance that have been described, but not systematically studied. A precise longitudinal assessment of endogenous cortisol production may be needed for optimal RA management. CONCLUSION: Apart from iatrogenic AI, an intrinsically compromised adrenal reserve in RA may have a pathogenetic role and interfere with effective management, thus deserving further research.

RESUMO

Deaths after ingestion of hydrogen peroxide (HP) are very rare, but poisoning due to consumption of HP is not uncommon. Most HP exposure involves common household-strength (3 %) HP and is usually benign. Even if it is not generally considered to be a poison, it can cause accidental death. HP results in morbidity through two main mechanisms: direct cytotoxic injury to tissues and formation of oxygen gas. We describe a rare case of a 2-year-old female who died after accidentally ingesting two sips of 35 % HP. For the first time, we provide histopathological images of the damage caused by HP in organic tissues.
