“…This is harder than it sounds, as women have less of a response to EPO than men, 232 and up to 25% of pregnant women treated with EPO do not respond. 233 At high altitude C a O 2 is increased by raising hemoglobin concentration. This preserves maternal and fetal oxygen delivery 178,234 despite a ~ 20% reduction in uterine artery blood flow in mothers, and an even greater decrement in fetal umbilical venous blood flow.…”

Although much progress is being made in understanding the molecular pathways in the placenta involved in the pathophysiology of pregnancy related disorders, a significant gap exists in utilizing this information for developing new drug therapies to improve pregnancy outcome. On March 5–6, 2015, the Eunice Kennedy Shriver National Institute of Child Health and Human Development of the National Institutes of Health sponsored a two day workshop titled Placental Origins of Adverse Pregnancy Outcomes: Potential Molecular Targets to begin to address this gap. Particular emphasis was given in the identification of important molecular pathways that could serve as drug targets and the advantages and disadvantages of targeting these particular pathways. This article is a summary of the proceedings of this workshop. A broad number of topics were covered ranging from basic placental biology to clinical trials. This included research in the basic biology of placentation, such as trophoblast migration and spiral artery remodeling, and trophoblast sensing and response to infectious and non-infectious agents. Research findings in these areas will be critical for formulating developing future treatments and developing therapies for the prevention of a number of pregnancy disorders of placental origin including preeclampsia, fetal growth restriction, and uterine inflammation. Research was also presented summarizing ongoing clinical efforts in the U.S. and in Europe testing novel interventions for preeclampsia and fetal growth restriction, including agents such as oral arginine supplementation, sildenafil, pravastatin, gene therapy using virally-delivered vascular endothelial growth factor, and oxygen supplementation therapy. Strategies were also proposed to improve fetal growth by enhancing nutrient transport to the fetus by modulating their placental transporters, as well as targeting placental mitochondrial dysfunction and oxidative stress to improve placental health. The roles of microRNAs and placental-derived exosomes, as well as messenger RNAs, were also discussed in the context of their use for diagnostics and as drug targets. The workshop discussed the aspect of safety and pharmacokinetic profiles of potential existing and new therapeutics that will need to be determined especially in the context of the unique pharmacokinetic properties of pregnancy, as well as the hurdles and pitfalls of translating research findings into practice. The workshop also discussed novel methods of drug delivery and targeting during pregnancy using macromolecular carriers, such as nanoparticles and biopolymers, to minimize placental drug transfer and hence fetal drug exposure. In closing, a major theme that developed from the workshop was that the scientific community needs to change their thinking of the pregnant women and her fetus as a vulnerable patient population for which drug development should be avoided, but rather thought of as a deprived population in need of more effective therapeutic interventions.

“…This modality in later gestation correlates with a carcinogenic effect and increased risk for leukaemogenesis or solid tumours within the first decade of life [101]. So far no teratogenic effects have been proven when granulocyte colony-stimulating factor or erythropoietin was needed to overcome treatment related cytopenia [102].…”

Presentation of Hodgkin lymphoma (HL) is distinctive in the infected individual being more advanced, accompanied by B symptoms and the presence of extranodal disease particularly lymphadenopathy of the head and neck. Bone marrow involvement may be found in over 50% of cases. Virtually all co express gamma-herpesvirus. Phenotypically there is prominence of the mixed-cellularity and lymphocyte depleted histopathologic subtypes that define an aggressive clinical course in comparison to other variants. Prior to the induction of cART, median survival was only 1-2 years. Notably the first chemotherapy trial using ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) in 21 patients, without treating the viral infection, resulted in a 43% complete remission rate accompanied by severe haematological toxicities but did not extend median survival with this being 1.5 years matching the negative cases.Significant change accompanied concomitant anti-retroviral therapy that could be given safely even with dose intensive regimens exemplified by BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone) in 12 patients or the Stanford V regimen (doxorubicin, vinblastine, mechlorethamine, etoposide, vincristine, bleomycin, prednisone) coupled with involved-field radiation for bulky disease studied in 59 patients. BEACOPP extended overall survival (OS) to 83% at 2 years. A similar trend was seen 1 when using the Stanford V regimen with an OS rate of 51% at 3 years, disease-free survival (DFS) of 68% and freedom from progression (FFP) in 60%. Additional benefits accrued from supportive care with stimulatory peptides such as G-CSF and when combined with bacterial prophylaxis results approached that found in the uninfected reference group. Current consensus holds this particular lymphoma as still among the non-AIDS defining cancers being lung, stomach, liver or anal despite these having recently gained more attention as several of these neoplasms may be occurring more commonly in the era of cART.While the relative risk of developing a non-AIDS-defining neoplasm in HIV-infected persons on the average is 2-3 times, the risk for developing HL in HIV-infected cases impressively ranges between 5 and 25 times when compared to the general population. Based on the precedent in which Kaposi sarcoma and the non-Hodgkin lymphomas distinctively alter the course of this retroviral infection in a way indistinguishable from concurrent Hodgkin lymphoma we propose that this entity be similarly regarded and the hypothesis tested in large randomised prospective study.

“…However, chronic use may induce neonatal withdrawal signs and symptoms and maternal addiction [47]. Treatment with erythropoietin and granulocyte colony-stimulating factor in chemotherapy-induced cytopenias is safe for both the fetus and the mother [48]. However, since data on the use of recombinant human erythropoietin (rhEPO) during pregnancy are insufficient, it can only be used if blood transfusion is contraindicated [49-51].…”

Gynecologic malignancy in pregnancy

Gynecologic malignancy during pregnancy is a stressful problem. For the diagnosis and treatment of malignancy during pregnancy, a multidisciplinary approach is needed. Patients should be advised about the benefits and risk of treatment. When selecting a treatment for malignancy during pregnancy, the physiologic changes that occur with the pregnancy should be considered. Various diagnostic procedures that do not harm the fetus can be used. Laparoscopic surgery or laparotomy may be safely performed. The staging approach and treatment should be standard. Systemic chemotherapy during the first trimester should be delayed if possible. Radiation therapy should preferably start postpartum. Although delivery should be delayed preferably until after 35 weeks of gestation, termination of pregnancy may be considered when immediate treatment is required. Subsequent pregnancies do not increase the risk of malignancy recurrence.
