Objective To determine the role of caspase-3, apoptosis-inducing factor (AIF), and B-cell lymphoma-2 (Bcl-2) expressions in term premature rupture of membrane (PROM). Methods An analytic observational study with case-control design was conducted, involving 52 subjects (37–42 weeks of gestation) who were divided into 2 groups: 26 cases of term delivery with PROM, and 26 controls of term delivery without PROM. The expressions of caspase-3, AIF, and Bcl-2 in the amniotic membrane were determined by immunohistochemistry. Data were analyzed using the chi-squared test. The risk of PROM was expressed by odds ratio (OR). Results There were no significant differences in age, parity and body mass index between the two groups (p > 0.05). High caspase-3 and AIF expressions increased the risk of PROM 17.64 times (OR = 17.64; 95% CI = 4.44–70.07; p = 0.001) and 9.45 times (OR = 9.45; 95% CI= 2.62–34.07; p = 0.001), respectively, while low Bcl-2 expression increased 10.39 times (OR = 10.39; 95% CI = 2.73–39.56; p = 0.001)the risk of PROM . Conclusion High caspase-3 and AIF expressions and low Bcl-2 expression were risk factors for term PROM. Caspase-dependent and independent pathways of apoptosis were involved in the mechanism of PROM in term pregnancy.

Thyroid crisis is an emergency in Endocrinology which is characterized by acute hypermetabolic with rapid deterioration which is one of non-obstetric maternal death cause. This condition is rare serious complication, affect about 1-2% of patients with hyperthyroidism. Unrecognized and untreated thyroid storm causing life threatening condition. Management of thyroid storm in pregnancy is aimed to reduce the synthesis and secretion of thyroid hormone and pregnancy management. Explain about optimal diagnostic and treatment strategies of pregnancy with thyroid storm. A 28 years woman admitted to Obstetrics Emergency Room, third pregnancy with 36 weeks 2 weeks gestation was complained of shortness of breath since 3 days ago. History of hyperthyroid since 1 year ago, often palpitate, sweating and tremor. History of consumption PTU 3x100 mg oral but lack of obey. History of hypertension since 27 weeks gestation. Physical examination found that blood pressure was 170/110 mmHg, pulse rate 130 bpm, respiratory rate bpm, 84% oxygen saturation, 38.5°C temperature. Diffuse tiroid gland was palpable with size 1 x 2 cm, ronkhi in whole lung field. Obstetric examination was found breech presentation with FHB: 131 bpm. Laboratory result were TSHs / FT4: 0.24 / 1.72, T4 Total: 104. Thyroid storm diagnostic based on Burch Wartofsky score: 55. Initial treatment performed with oxygen administration, loop diuretics, chest X-ray examination and echocardiography. Followed by PTU therapy, lugolization and corticosteroids. After 48 hours of stabilization, we performed cesarean section and postoperative care at Intensive Care Unit. Thyroid storm is rare pregnancy complication. Diagnostic criteria using Burch and Wartofsky score. Management of thyroid storm in pregnancy includes anti thyroid drugs, lugol solution, corticosteroids and pregnancy management. Diuretic therapy is given due to fluid overload, besides that screening of thyroid hormone profile is important during antenatal care.

BACKGROUND:The premature rupture of membranes (PROM) represents an obstetric issue causing significant maternal and neonatal morbidity and mortality. Although protein 53 (p53), one of the proapoptotic proteins suspected of causing PROM at the molecular level is closely correlated with the occurrence of PROM, the exact mechanism remains still unclear.AIM:This study aims to investigate the hypothesis that p53 expression and the apoptotic index play a role in the PROM mechanism.METHODS:Placentas from 20 pregnancies (37–42 weeks gestation) and 20 pregnancies complicated by PROM were collected at delivery. The independent variable is represented by pregnant mothers with a single live fetus experiencing PROM (followed by labour and birth) while without PROM mothers represent the control. The research material was taken from the amnion tissue in the placenta. Also, p53 and apoptotic index (TUNEL) immunohistochemical examination were conducted at the Integrated Biomedical Laboratory, Medical Faculty of Udayana University, Bali. The correlation between the apoptotic index and p53 expression of the PROM group was tested using a McNemar Test.RESULTS:No statistically significant differences were found between the two groups (p > 0.05). There was a significant difference in p53 expression in PROM cases compared to those without PROM (11.15 + 5.59% vs. 0.95 + 2.52%) with χ2 = 19.538 and p = 0.001. The apoptotic index in PROM cases was higher than in those without PROM (19.10 + 5.63% vs. 1.15 + 2.46%) with χ2 = 32.40 and p = 0.001. There was a strong correlation between p53 expression and PROM with PR = 3.449 (95% CI = 1.801-6.605; p = 0.001). There was a strong correlation between the apoptotic index and PROM with PR = 19 (95% CI = 2.81-128.69; p = 0.001).CONCLUSION:p53 expression and the apoptotic index of amniotic membrane cells in cases of PROM was higher than in those without PROM, there was a strong correlation between p53 expression and apoptotic index with the occurrence of PROM.

Background: Premature rupture of membrane (PROM) remains a problem in obstetrics, the mechanisms of PROM have not been clearly defined. Apoptosis is thought to play a key role in the mechanism, via caspase-dependent and caspase-independent pathways. Caspase-3, Apoptosis-inducing factor (AIF), and anti-apoptosis B-cell lymphoma 2 (Bcl-2) are hypothesized to be involved in PROM. Objective: To determine the role of caspase-dependent and caspase-independent pathways in the mechanism of PROM. Materials and Methods: This was a case-control study involving 42 pregnant women with gestational age between 20-42 wk. Participants were divided into the case group (with PROM) and control group (without PROM). Amniotic membranes were collected immediately after the delivery, and samples were taken from the site of membrane rupture. Immunohistochemical examination was done to determine the expression of Caspase-3, AIF, and Bcl-2. Results: The expressions of Caspase-3 (OR = 9.75; 95% CI = 2.16-43.95; p = 0.001) and AIF (OR = 6.60; 95% CI = 1.48-29.36; p = 0.009) were significantly increased, whereas, Bcl-2 expressions (OR = 8.00; 95% CI = 1.79-35.74; p = 0.004) were significantly decreased in the case group. Conclusion: High Caspase-3, AIF, and low Bcl-2 expression were the risk factors for PROM. Thus, it is evident that caspase-dependent and caspase-independent pathways are involved in the mechanism of PROM. Key words: Premature, Membrane, Apoptosis, Caspase, Pregnancy.
