Ovarian Syndrome

Adipokines are cytokines produced mainly by adipose tissue, besides many other tissues such as placenta, ovaries, peripheral-blood mononuclear cells, liver, muscle, kidney, heart, and bone marrow. Adipokines play a significant role in the metabolic syndrome and in cardiovascular diseases, have implications in regulating insulin sensitivity and inflammation, and have significant effects on growth and reproductive function. The objective of this review was to analyze the functions known today of adiponectin, leptin, resistin, and visfatin from placenta throughout childhood and adolescence. It is well known now that their serum concentrations during pregnancy and lactation have long-term effects beyond the fetus and newborn. With regard to puberty, adipokines are involved in the regulation of the relationship between nutritional status and normal physiology or disorders of puberty and altered gonadal function, as, for example, premature pubarche and polycystic ovarian syndrome (PCOS). Cytokines are involved in the maturation of oocytes and in the regular progression of puberty and pregnancy.

Ovarian Syndrome

Polycystic ovarian syndrome (PCOS) may clinically manifest for the 1st time in adolescence. Hyperandrogenemia and oligo-anovulation are the two essential criteria for the diagnosis of PCOS. PCOS has long-term effects on cardiovascular, endocrinal, reproductive, and metabolic health. Early management of PCOS mitigates its long-term effects on health. Therapeutic lifestyle management and psychological counseling form the main stay of treatment in adolescence. Diagnosis of PCOS in adolescence is revisited and confirmed in adulthood. Management of PCOS is multidisciplinary and requires long-term regular follow-up in adolescence and adulthood.

Abstract Background Early combined antiretroviral therapy (cART) limits the total HIV-DNA load in children. However, data on its impact in older children and adolescents remain scarce. This study aims to compare HIV reservoirs in children (5-12 years) and adolescents (13-17 years) who started cART before 6 months (early (E-)group) or after 2 years old (late (L-)group). Methods The ANRS-EP59-CLEAC study prospectively enrolled 76 HIV-1 perinatally-infected patients who reached HIV-RNA<400 copies/mL less than 24 months after cART initiation, regardless of subsequent viral suppression (E-group: 27 children, 9 adolescents; L-group: 19 children, 21 adolescents). Total and integrated HIV-DNA were quantified in blood and in CD4+ T cell subsets. A substudy assessed HIV reservoir inducibility after ex vivo peripheral blood mononuclear cells (PBMCs) stimulation. Results Total HIV-DNA levels were lower in early- than late-treated patients (Children: 2.14 vs 2.87 log cp/million PBMCs, p<0.0001; Adolescents: 2.25 vs 2.74log, p<0.0001). Low reservoir was independently associated with treatment precocity, protective HLA and low cumulative viremia since cART initiation. The 60 participants with undetectable integrated HIV-DNA started cART earlier than the other patients (4 vs 54 months, p=0.03). In those with sustained virological control, transitional memory and effector memory CD4+T cells were less infected in the E-group than in the L-group (p=0.03 and 0.02, respectively). Viral inducibility of reservoir cells after normalization to HIV-DNA levels was similar between the groups. Conclusions Early cART results in a smaller blood HIV reservoir until adolescence, but all tested participants had an inducible reservoir. This deserves cautious consideration for HIV remission strategies.

AbstractPolycystic ovarian syndrome (PCOS) is the most common endocrinopathy in women and can be associated with significant adverse sequelae that can affect overall long-term health and well-being. This review provides a succinct but comprehensive overview of our current understanding concerning the known morbidities of PCOS, beginning with a review of the importance of the different phenotypes of PCOS in determining long-term morbidity, the confounding impact of obesity on health outcomes in PCOS, and the immediate short-term consequences of the disorder (including dermatologic, reproductive, and mood disturbances). The longer-term morbidities of PCOS are then reviewed including metabolic consequences (impaired glucose tolerance and type 2 diabetes mellitus, metabolic syndrome, and nonalcoholic fatty liver disease), dyslipidemia and vascular dysfunction (including hypertension and increased incidences of cerebrovascular accidents and thromboembolisms on oral contraceptives), neoplastic (primarily endometrial adenocarcinoma), and mental health disorders (including greater incidences of depressive and anxiety disturbances and psychosexual dysfunction). In conclusion, strategies for the prevention and amelioration of long-term morbidities in PCOS are presented.

Abstract Human peripheral blood mononuclear cells (PBMCs) originate from hematopoietic stem cells (HSCs) in the bone marrow, which mainly includes lymphocytes (T cells, B cells, and natural killer [NK] cells) and monocytes. Cryopreserved PBMCs providing biobank resources are crucial for clinical application or scientific research. Here, we used flow cytometry to explore the influence of long-term cryopreservation on the quality of PBMCs with the aim of providing important evidence for the effective utilization of biobank resources. The PBMCs were isolated from the peripheral blood, which was collected from volunteers in the hospital. After long-term cryopreservation in liquid nitrogen, we analyzed the changes in cell numbers, viability, and multiple subtypes of PBMCs and studied the apoptosis, proliferation, activation, function, and status of T cells in comparison with freshly isolated PBMCs by flow cytometry, and then further tracked the effects of long-term cryopreservation on the same sample. Although the different cell types in the PBMCs dynamically changed compared with those in the freshly isolated samples, PBMC recovery and viability remained stable after long-term cryopreservation, and the number of most innate immune cells (e.g., monocytes and B cells) was significantly reduced compared to that of the freshly isolated PBMCs or long-term cryopreserved PBMCs; more importantly, the proportion of T cell subtypes, apoptosis, proliferation, and functional T cells, except for Tregs, were not affected by long-term cryopreservation. However, the proportions of activated T, naïve T, central memory T, effector T, and effector memory T cells dynamically changed after long-term cryopreservation. This article provides important evidence for the effective utilization of biobank resources. Long-term cryopreserved PBMCs can be partly used as biological resources for clinical research or basic studies, but the effect of cryopreservation on PBMCs should be considered when selecting cell samples, especially in research relating to activating or inhibiting function.

The coronavirus disease 2019 (COVID-19) pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) affects millions of people and killed hundred-thousands of individuals. While acute and intermediate interactions between SARS-CoV-2 and the immune system have been studied extensively, long-term impacts on the cellular immune system remained to be analyzed. Here, we comprehensively characterized immunological changes in peripheral blood mononuclear cells in 49 COVID-19 convalescent individuals (CI) in comparison to 27 matched SARS-CoV-2 unexposed individuals (UI). Despite recovery from the disease for more than 2 months, CI showed significant decreases in frequencies of invariant NKT and NKT-like cells compared to UI. Concomitant with the decrease in NKT-like cells, an increase in the percentage of Annexin V and 7-AAD double positive NKT-like cells was detected, suggesting that the reduction in NKT-like cells results from cell death months after recovery. Significant increases in regulatory T cell frequencies, TIM-3 expression on CD4 and CD8 T cells, as well as PD-L1 expression on B cells were also observed in CI, while the cytotoxic potential of T cells and NKT-like cells, defined by GzmB expression, was significantly diminished. However, both CD4 and CD8 T cells of CI showed increased Ki67 expression and were fully capable to proliferate and produce effector cytokines upon TCR stimulation. Collectively, we provide the first comprehensive characterization of immune signatures in patients recovering from SARS-CoV-2 infection, suggesting that the cellular immune system of COVID-19 patients is still under a sustained influence even months after the recovery from disease.

High Prevalence

SummaryIn a previous study, we have determined the prevalence of serum HGV-RNA in patients with congenital clotting disorders. Twenty-six (15%) of 175 patients investigated were serum HGV-RNA positive. In addition, HGV-RNA was detectable in peripheral blood mononuclear cells (PBMC) in ten percent of the cases, three of these patients were serum HGV-RNA negative.In the present study, we have determined the prevalence of anti-HGV-E2 antibodies in the same patient population. Anti-HGV-E2 as determined by ELISA was detected in 45 patients (25.7%). Forty of these patients were serum HGV-RNA negative.Ninety-two percent of the 26 HGV viremic patients and all but one patient (44 patients) with detectable anti-HGV-E2 had coinfection with the hepatitis C virus (HCV). Of these coinfected patients, 62.5% of HGV viremic patients and 53% of anti-HGV-E2 positive patients showed elevated serum ALT levels. Anti-HGV-E2 seroconversion is thus not associated with HCV infection. Two patients who were solely infected with HGV had normal serum ALT levels. In a retrospective longitudinal study, we have observed in 15 patients that serum HGV-RNA persisted during one to 19 years of follow-up, while anti-HGV-E2 was repeatedly negative. Five additional patients who were anti-HGV-E2 positive with concomitant detectable HGV-RNA (4 patients in serum and 1 patient in PBMC) became HGV-RNA negative during follow-up, ranging from 1 to 8 years after the first detection of anti-HGV-E2 antibodies. Two patients had lost anti-HGV-E2 antibodies 3 to 6 years after the seroconversion without the re-appearance of serum HGV-RNA. From these findings, it is clear that the prevalence rate of HGV infection in patients with clotting disorders as determined by PCR assay for HGV-RNA and anti-HGV-E2 by ELISA is actually higher than the prevalence of HGV viremia. Although HGV viremia may persist for longer than 19 years, most of the patients infected with HGV may clear the viremia spontaneously. The clearance of viremia is usually associated with seroconversion to anti-HGVE2. In addition, anti-HGV-E2 may be lost during years of follow-up without the reappearance of the HGV-RNA. Although HGV infection does not seem to influence the fate of HCV infection and does not induce increased levels of serum ALT, the clinical significance of long-term infection remains to be established.
