ABSTRACT

Chronic hepatitis C (HCV) in women of childbearing age is a major public health concern with ∼15 million women aged 15-49 years living with HCV globally in 2019. Evidence suggests HCV in pregnancy is associated with adverse pregnancy and infant outcomes. This includes ∼6% risk of infants acquiring HCV vertically, and this is the leading cause of HCV in children globally. However, few countries offer routine universal antenatal HCV screening, and direct-acting antivirals (DAAs) are not approved for pregnant or breastfeeding women although small clinical trials are ongoing. We conducted a survey of pregnant and postpartum women in 3 high HCV burden lower-middle-income countries to assess the acceptability of universal antenatal HCV screening and DAA treatment in the scenario that DAAs are approved for use in pregnancy. Pregnant and postpartum women attending antenatal clinics in Egypt, Pakistan, and Ukraine were invited to complete a survey and provide demographic and clinical data on their HCV status. Among the 630 women included (n=210 per country), 73% were pregnant and 27% postpartum, 27% were ever HCV antibody or PCR positive. Overall, 586 (93%) reported acceptability of universal antenatal HCV screening and 544 (88%) would take DAAs in pregnancy (92%, 98%, and 73% in Egypt, Pakistan, and Ukraine, respectively). Most said they would take DAAs in pregnancy to prevent vertical acquisition and other risks for the baby, and a smaller proportion would take DAAs for maternal cure. Our findings suggest that should DAAs be approved for use in pregnancy, the uptake of both HCV screening and DAA treatment may be high in women living in lower-middle-income countries.

ABSTRACT

Rheumatoid arthritis (RA) is a chronic inflammatory condition, an autoimmune disease that affects the joints, and a multifactorial disease that results from interactions between environmental, genetic, and personal and lifestyle factors. This study was designed to assess the effects of curcumin, bone marrow-derived mesenchymal stem cells (BM-MSCs), and their coadministration on complete Freund's adjuvant- (CFA-) induced arthritis in male and female albino rats. Parameters including swelling of the joint, blood indices of pro-/antioxidant status, cytokines and histopathological examination of joints, and testis and ovary were investigated. RA was induced by a single dose of subcutaneous injection of 0.1 mL CFA into a footpad of the right hind leg of rats. Arthritic rats were treated with curcumin (100 mg/kg b.wt./day) by oral gavage for 21 days and/or treated with three weekly intravenous injections of BM-MSCs (1 × 106 cells/rat/week) in phosphate-buffered saline (PBS). The treatment with curcumin and BM-MSCs singly or together significantly (P < 0.05) improved the bioindicators of oxidative stress and nonenzymatic and enzymatic antioxidants in sera of female rats more than in those of males. Curcumin and BM-MSCs significantly (P < 0.05) improved the elevated TNF-α level and the lowered IL-10 level in the arthritic rats. Furthermore, joint, testis, and ovary histological changes were remarkably amended as a result of treatment with curcumin and BM-MSCs. Thus, it can be concluded that both curcumin and BM-MSCs could have antiarthritic efficacies as well as protective effects to the testes and ovaries which may be mediated via their anti-inflammatory and immunomodulatory potentials as well as oxidative stress modulatory effects.

ABSTRACT

OBJECTIVES: Despite the high burden of hepatitis C virus (HCV) infection in Egypt, screening of pregnant women is not yet universal, making national and global elimination unlikely. This study assessed the proportion of pregnant women who were screened for HCV infection at delivery, the prevalence and risk factors for HCV infection, the associated adverse neonatal outcomes, and the real-life linkage to care of infected women and follow-up of their infants' HCV status and timing of testing. METHODS: Data were collected from medical records of a retrospective cohort of all pregnant women who were admitted to a university hospital in Cairo for delivery between January and June 2018 (n = 6734). HCV antibody- and RNA-positive women and their infants were prospectively followed-up by phone interviews till September 2019. RESULTS: 2177 (32.3%) pregnant women were screened for HCV infection. 19 (0.9%) tested HCV antibody- and RNA-positive. Being ≥ 30 years old (ORa 3.6, 95% CI: 1.4-9.2; P = 0.009), history of abortion (ORa 3.5, 95% CI: 1.2-10.3; P = 0.022) and blood transfusion (ORa 29.1, 95% CI: 9.6-88.4; P < 0.001) were independent risk factors for infection. Adverse neonatal outcomes did not vary significantly among HCV antibody-positive and antibody-negative women. Only 13 (68.4%) HCV antibody- and RNA-positive women started treatment with direct-acting antivirals (DAAs) post-breastfeeding (two completed the treatment course and were cured). Four (21.1%) did not start treatment, and two (10.5%) were lost to follow-up. All infants of the 13 HCV antibody- and RNA-positive women who started DAA therapy tested HCV RNA-negative within their first year of life. CONCLUSION: Extending screening services to all pregnant women and better linkage to care are essential for the national elimination of HCV infection.


OBJECTIFS: Malgré la charge élevée de l'infection par le virus de l'hépatite C (VHC) en Egypte, le dépistage des femmes enceintes n'est pas encore universel, ce qui rend peu probable l'élimination nationale et mondiale. Cette étude a évalué la proportion de femmes enceintes qui ont été dépistées pour l'infection par le VHC à l'accouchement, la prévalence et les facteurs de risque d'infection par le VHC, les résultats néonatals indésirables associés et le ralliement réel avec les soins aux femmes infectées et le suivi du statut VHC de leurs nourrissons et le calendrier des tests. MÉTHODES: Les données ont été collectées à partir des dossiers médicaux d'une cohorte rétrospective de toutes les femmes enceintes admises dans un hôpital universitaire du Caire pour un accouchement entre janvier et juin 2018 (n = 6734). Les femmes testées positives pour les anticorps et l'ARN du VHC et leurs nourrissons ont fait l'objet d'un suivi prospectif par des entretiens téléphoniques jusqu'en septembre 2019. RÉSULTATS: 2.155 (32,3%) femmes enceintes ont été dépistées pour l'infection au VHC. 19 (0,9%) ont été testées positives pour les anticorps et l'ARN du VHC. Avoir ≥30 ans (ORa: 3,6 ; IC95%: 1,4-9,2; p = 0,009), les antécédents d'avortement (ORa : 3,5 ; IC 95%: 1,2-10,3; p = 0,022) et la transfusion sanguine (ORa: 29,1 ; IC95%: 9,6-88,4; p <0,001) étaient des facteurs de risque indépendants d'infection. Les résultats néonatals défavorables ne variaient pas de manière significative entre les femmes positives et négatives aux anticorps anti-VHC. Seules 13 (68,4%) femmes positives pour les anticorps et l'ARN du VHC ont commencé un traitement avec des antiviraux à action directe (AAD) après l'allaitement (deux ont terminé le traitement et ont été guéries). Quatre (21,1%) n'ont pas commencé le traitement et deux (10,5%) ont été perdus de vue. Tous les nourrissons des 13 femmes positives pour l'anticorps et l'ARN du VHC qui ont commencé un traitement par AAD ont été testés négatifs pour l'ARN du VHC au cours de leur première année de vie. CONCLUSION: L'extension des services de dépistage à toutes les femmes enceintes et un meilleur lien avec les soins sont essentiels pour l'élimination nationale de l'infection par le VHC.

ABSTRACT

Cyclosporine A (CsA) is an immunosuppressor agent, which is most frequently used in transplant surgeries and in the treatment of autoimmune diseases. This study was undertaken to investigate the protective effects of ellagic acid (EA) against CsA-induced testicular histopathology and ultrastructure changes, oxidative stress, and cytogenotoxicity in male albino rats. Rats were divided into six groups; the first group was used as a control, the second group received a subcutaneous injection of slightly alkaline solution, the third group received olive oil orally, the fourth group was injected subcutaneously with EA at a dose of 10 mg/kg b. wt./day, the fifth group was treated with CsA as oral solution at a dose of 15 mg/kg b. wt for 30 days, and the sixth group was treated with CsA simultaneously with EA. Treatment with EA simultaneously with CsA resulted in significant protection. The positive control animals taking CsA alone showed marked histopathological, ultrastructure, and genetic manifestations accompanied by an elevated content of lipid peroxidation and marked reduction of catalase (CAT), peroxidase (Px) activity, and glutathione concentration in the homogenate of testis tissues. The toxic side effects in testis and bone marrow tissues were greatly ablated with a significant reduction in lipid peroxidation level and elevation in CAT and Px activities and glutathione concentration when using EA. Thus, EA may be used in combination with CsA to improve the histopathological, oxidative stress, and cytogenotoxicity parameters of testicular toxicity induced by CsA due to its antioxidant effects.
