ABSTRACT

BACKGROUND: Pregnancy in patients with systemic lupus erythematosus is considered a high risk one since it is associated with a higher rate of maternal-fetal complications compared with the pregnancies in healthy women. OBJECTIVES: The aim of this study was to describe the maternal-fetal outcomes in a cohort of Mexican patients with systemic lupus erythematosus and to identify risk factors associated with adverse maternal and fetal outcomes. PATIENTS AND METHODS: A cohort of pregnant lupus patients was analyzed. Maternal-fetal complications were described, and clinical, biochemical, and immunological variables associated with obstetric adverse outcomes were studied. Descriptive statistics, comparison of variables using appropriate tests, and finally logistic regression analysis were performed to identify potential risk factors for adverse maternal and fetal outcomes. RESULTS: A total of 351 pregnancies were included in a 10-year period. The most frequently observed maternal adverse outcomes were lupus flare (35%) and preeclampsia (14.5%). Active lupus before pregnancy (hazards ratio [HR], 3.7; 95% confidence interval [CI], 1.1-12.5; p = 0.003) was a predictor for these complications, whereas the use of antimalarial drugs (HR, 0.4; 95% CI, 0.2-0.7; p = 0.007) was a protective factor. The most frequent fetal adverse outcomes were preterm birth (38.1%), miscarriages (10%), and low birth weight babies (28%), and very low birth weight newborns (11%). Proteinuria in early pregnancy (HR, 7.1; 95% CI, 1.01-50.3; p = 0.04) and preeclampsia (HR, 9.3; 95% CI, 1.7-49.7; p = 0.009) were risk factors associated with these complications. CONCLUSIONS: Variables related to systemic lupus erythematosus activity predict an adverse maternal outcome, whereas proteinuria in early pregnancy and preeclampsia are associated with an adverse fetal outcome.

ABSTRACT

INTRODUCTION: Several factors have been associated with the development of preeclampsia in women with systemic lupus erythematosus (SLE). OBJECTIVE: To identify risk factors associated with preeclampsia in patients with SLE and its impact on fetal outcomes. PATIENTS AND METHODS: We studied a prospective cohort of pregnancies in women with SLE from January 2009 to December 2018. Demographic, clinical, serological and drug use characteristics were compared between patients who developed preeclampsia and those who did not, as well as the main neonatal outcomes. An adjusted logistic regression analysis was performed to identify factors potentially associated with preeclampsia. RESULTS: We studied 316 pregnancies of 20 or more weeks of gestation. A total of 46 pregnancies (14.5%) were complicated by preeclampsia. A higher frequency of active disease before pregnancy (24.4% vs 11.3%, P = .01) and history of lupus nephritis (56.5% vs 30.1%, P < .001) were found in those patients who developed preeclampsia compared to those who did not. Preeclampsia was associated with a higher rate of prematurity, births of very low birth weight, stillbirth, and neonatal death. The multivariate analysis showed that the activity of the disease before (relative risk [RR] 2.7, 95% CI 1.04-7.4, P = .04) and during pregnancy (RR 3.0, 95% CI 1.0-9.1, P = .04) was associated with the development of preeclampsia. The use of antimalarial drugs during pregnancy was associated with a lower risk of preeclampsia (RR 0.21, 95% CI 0.08-0.53, P < .001). CONCLUSIONS: Our study suggests that the use of antimalarial drugs during pregnancy reduces the risk of preeclampsia in lupus pregnancies.

ABSTRACT

Background: Probiotics have been used in the adjuvant treatment of Ulcerative Colitis (UC). Objective: To evaluate the role of a combination of probiotics on the clinical, histological changes and feeding tolerance in patients with UC. Methods: An open UC patients with mild to moderate activity and clinical trial was conducted. Patients were randomized to receive or a combination of 6 strains of probiotics for 3 months while continuing their drug treatment established. UC activity was assessed by Truelove and Witts scale and histological findings by Gupta index. Descriptive statistics, Chi square test and Student t test for comparison of the two groups was performed. Results: In each group 17 patients were included. An improvement was found in the disease activity (52.9% vs. 23.5%, p = 0.07) and in histologic index (82.3% vs. 41.1%, p = 0.03) in patients treated with probiotics compared to the control group. Improved food tolerance was also observed in patients treated with probiotics. Conclusion: The study shows a beneficial short-term effect on symptoms, histological findings and feeding tolerance with the administration of a combination of 6 strains of probiotics in patients with UC.

ABSTRACT

BACKGROUND/AIMS: One hallmark of chronic liver disease in patients with portal hypertension is the formation of portal-systemic collaterals in which angiogenesis has a fundamental role. We studied patients with chronic liver disease undergoing liver transplantation to correlate levels of circulating angiogenic factors in portal and peripheral circulation with portal pressure and portal-systemic collaterals. METHODS: Sixteen patients who underwent liver transplantation were enrolled. During transplant surgery, we determined portal venous pressure and portal-systemic collateral formation. We determined angiogenics mediator levels in systemic and portal plasma. Peripheral plasma from healthy donors was measured as controls. RESULTS: Vascular endothelial growth factor (VEGF)-R1 and 2, Ang-1 and 2, Tie2, FGF- 1 and 2, CD163, PDGFR-ß, PDGFsRα, PDGF-AB and BB, CD163, TGF-ß VASH-1 levels were significantly different in the controls in comparison to cases. Significantly decreased portal venous levels of Ang-1, FGF-1, PDGF-AB/BB, and CC were observed in patients with higher portal pressure. Peripheral VEGF, Ang-1, pPDGF-AB, BB, and CC were significantly decreased in patients with more severe collateral formation. While peripheral VEGF-R1 was higher in patients with severe collateral formation. For portal circulation, VEGF, Ang-1, -pPDGF-AB, BB, and CC were significantly decreased in patients with more severe collateral formation Conclusions: Angiogenesis factors correlated with portal pressure and collateral formation and different patterns of circulating angiogenesis mediators were found in peripheral and portal blood of patients with chronic liver disease. These results support the importance of angiogenic pathways in cirrhosis and portal hypertension and highlight areas for further study to identify clinically useful noninvasive markers of portal pressure and collateral formation.

ABSTRACT

To compare the maternal and fetal outcomes between childhood-onset and adult-onset systemic lupus erythematosus (SLE), we reviewed the medical records of SLE pregnant women treated from January 2005 to August 2013. For comparison, patients were allocated to one of the two groups, those pregnant patients with SLE onset before 18 years of age (childhood-onset) and ≥18 years (adult-onset). The patients were evaluated at least once in each trimester and postpartum. Relevant maternal and fetal outcomes were extracted, such as lupus flare, preeclampsia/eclampsia, rate of liveborns, fetal loss (spontaneous abortion and stillbirth), term delivery, preterm birth, neonatal death, low birth weight, low birth weight at term, and congenital malformations. We studied 186 pregnancies (in 180 women), 58 of them had childhood-onset SLE, and the remaining 128 had adult-onset SLE. The rate of maternal and fetal complications was similar in both groups. Multivariate analysis showed that active SLE before pregnancy, primigravida, renal flare, preeclampsia, lupus flare, anticardiolipin antibodies, and low serum complement were associated with an increased risk of poor maternal and fetal outcomes. The diagnosis of childhood-onset had no impact on maternal-fetal outcome. The maternal and fetal outcome in women with childhood-onset SLE is similar to that reported in women with adult-onset SLE. Pregnancy in women with childhood-onset SLE should not be contraindicated if the disease is well controlled.

ABSTRACT

OBJECTIVE: To report our experience in maternal-fetal outcome in women with RA in a national medical referral center. METHODS: A retrospective analysis of the records of pregnant women with rheumatoid arthritis attending at a Pregnancy and Autoimmune Rheumatic Diseases Clinic was performed. Maternal-fetal outcomes such as disease activity, preclampsia/eclampsia, rate of live births, abortions, stillbirths, preterm birth, weeks of gestation, birth weight, congenital malformations and use of anti-rheumatic drugs were studied. RESULTS: We included 73 pregnancies in 72 patients. Disease activity was documented in 47.2% of patients during pregnancy and/or postpartum and 87.7% of patients received some antirheumatic drug. Preclampsia developed in 8.2% of cases. The live birth rate was 98.6%, with preterm delivery in 15.9% and low weight at term in 17.6% of cases. Cesarean section was performed in 77.1% of cases. The disease activity was not associated with a higher percentage of maternal-fetal complications. CONCLUSIONS: Our study showed that most patients do not experience significant activity of RA during pregnancy, fetal outcome is satisfactory and disease activity did not appear to influence significantly the obstetric outcome.

ABSTRACT

Background: Preservation solutions are critical for organ transplantation. In liver transplant (LT), the solution developed by the University Of Wisconsin (UW) is the gold-standard to perfuse deceased brain death donor (DBD) grafts. Histidine-Tryptophan-Ketoglutarate (HTK), formerly a cardioplegic infusion, has been also used in solid organ transplantation. Aim: To compare the outcomes of LT in our center using either HTK or UW solution. Patients and Methods: Retrospective study including 93 LT DBD liver grafts in 89 patients transplanted between March 1994 and July 2010. Forty-eight grafts were preserved with UW and 45 with HTK. Donor and recipient demographics, total infused volume, cold ischemia time, post-reperfusion biopsy, liver function tests, incidence of biliary complications, acute rejection and 12-month graft and patient survival were assessed. Preservation solution costs per liver graft were also recorded. Results: Donor and recipient demographics were similar. When comparing UW and HTK, no differences were observed in cold ischemia time (9.6 ± 3 and 8.7 ± 2 h respectively, p = 0.23), biliary complications, the incidence of acute rejection, primary or delayed graft dysfunction. Histology on post-reperfusion biopsies revealed no differences between groups. The infused volume was significantly higher with HTK than with UW (9 (5-16) and 6 (3-11) l, p < 0.001). The cost per procurement was remarkably lower using HTK. Conclusions: Perfusion of DBD liver grafts with HTK is clinically equivalent to UW, with a significant cost reduction.

ABSTRACT

INTRODUCTION: Steatotic livers have been associated with greater risk of allograft dysfunction in liver transplantation. Our aim was to determinate the prevalence of steatosis in grafts from deceased donors in Chile and to assess the utility of a protocol-bench biopsy as an outcome predictor of steatotic grafts in our transplant program. MATERIAL AND METHODS: We prospectively performed protocol-bench graft biopsies from March 2004 to January 2009. Biopsies were analyzed and classified by two independent pathologists. Steatosis severity was graded as normal from absent to < 6%; grade 1: 6-33%; grade 2: > 33-66% and grade 3: > 66%. RESULTS: We analyzed 58 liver grafts from deceased donors. Twenty-nine grafts (50%) were steatotic; 9 of them (16%) with grade 3. Donor age (p < 0.001) and BMI over 25 kg/m 2 (p = 0.012) were significantly associated with the presence of steatosis. There were two primary non-functions (PNF); both in a grade 3 steatotic graft. The 3-year overall survival was lower among recipients with macrovesicular steatotic graft (57%) than recipients with microvesicular (85%) or non-steatotic grafts (95%) (p = 0.026). CONCLUSION: Macrovesicular steatosis was associated with a poor outcome in this series. A protocol bench-biopsy would be useful to identify these grafts.

ABSTRACT

Operational tolerance after liver transplantation has been described in around 20% of the recipients. These patients are able to maintain a normal graft function in the absence of immunosuppressive drugs, thus being free of adverse effects that are common and frequently severe. Here we present a well-documented case of operational tolerance after liver transplantation and discuss current concepts on this topic with emphasis on recent findings that will potentially allow for identifying graft-tolerant patients.

ABSTRACT

Diffuse large B-cell non-Hodgkin's lymphoma (LDCGB) is one of the best examples of chemotherapy curable malignant diseases. This "Oncoguía SEOM" summarizes the basic directions of staging and recommended treatment options. The staging study should be thorough and includes clinical, laboratory, diagnostic imaging and nuclear medicine. Treatment depends on patient characteristics and comorbidity and on disease extension and prognostic factors. In localized cases, chemoimmunotherapy (CHOP-R) of short duration, followed by involved-field irradiation is the preferred option. In advanced stages, the association of CHOP-like chemotherapy and Rituximab has been a major breakthrough in terms of cure rate. It is important do not forget the supportive treatment in these patients.

ABSTRACT

Acute liver failure has a mortality rate in excess of 80%. Most deaths are attributed to brain edema with intracranial hypertension and herniation of structures, where ammonium plays a major role in its generation. We report an 18 year-old female with a fulminant hepatic failure caused by virus A infection. The patient developed a profound sopor and required mechanical ventilation. A CT scan showed the presence of brain edema and intracranial hypertension. A Raudemic catheter was inserted to measure intracranial pressure and brain temperature. Intracranial hypertension became refractory and intravascular hypothermia was started, reducing brain temperature to 33 degrees C. Seventy two hours later, a liver transplantation was performed. After testing graft perfusion, rewarming was started, completing 122 hours of hypothermia at 33 degrees C. The patient was discharged in good conditions after 69 days of hospitalization.

ABSTRACT

An 80-year-old man was admitted to hospital with low-grade fever, weight loss, asthenia and anorexia. Physical examination revealed generalised ichthyosis with palmoplantar hyperkeratosis. CT scan showed retroperitoneal and inguinal lymph node enlargement. An inguinal lymph node biopsy revealed Hodgkin's disease (nodular-sclerosing subtype). The patient received chemotherapy, showing a clear improvement of both skin lesions and lymph nodes.

ABSTRACT

Hepatopulmonary syndrome (HPS) is a complication of portal hypertension (PH) defined by the presence of liver disease, abnormal pulmonary gas exchange and evidence of intrapulmonary vascular dilatations (IPVD) producing a right to left intrapulmonary shunt. Liver transplantation (LT) is the treatment of choice; however, severe hypoxemia may contraindicate LT. The use of transjugular intrahepatic portosystemic shunts (TIPS) could be effective in HPS, although available data is limited. AIM: To report a clinical case of severe HPS treated sequentially with TIPS and LT. CASE REPORT: A 46 year old female cirrhotic patient presented with rapidly progressive dyspnea, hypoxemia (PaO2 60 mmHg, SaO2 92%) and increased alveolar-arterial oxygen gradient (A-a) (46 mmHg). She also had orthodeoxia (SaO2 87% in sitting position, but 91% in a prone position). A CT scan and pulmonary angiography were normal. Spirometric assessment showed a mild restrictive pattern and a desaturation was observed in a six-minute walking test. Contrast-enhanced echocardiography (CEE) showed intrapulmonary shunting. A HPS was diagnosed and liver transplantation was disregarded due to severe hypoxemia. The patient underwent TIPS placement. After four weeks, a significant improvement of dyspnea and a complete remission of orthodeoxia were seen. One year later, the patient was successfully transplanted. Interestingly, six months after LT, and in the absence of dyspnea, a new CEE showed persistent passing of bubbles to the left cavities. COMMENTS/CONCLUSION: Persistent right-to-left shunt after TIPS placement and liver transplantation in spite of the improvement of pulmonary function tests suggests long-term persistence of structural changes in the pulmonary vascular tree after liver transplantation. Because of lack of data, it is not possible to recommend the routine use of TIPS as a part of the conventional management of HPS. However, in patients with severe hypoxemia TIPS placement can reasonably be used as a bridge towards transplantation.

ABSTRACT

Primary ovarian Burkitt lymphoma (BL) is a rare neoplasm in adults. We report a 30-year-old woman diagnosed with primary bilateral ovarian BL. She presented features of a twisted ovarian cyst and underwent bilateral salpingo-oophorectomy. The histopathologic evaluation yielded the diagnosis of BL and subsequently she received chemoimmunotherapy with CODOX-M-IVAC plus rituximab (anti-CD20 monoclonal antibody).

ABSTRACT

Background: Orthotopic liver transplantation (OLT) is the treatment of choice for multiple acute and chronic end-stage liver diseases as well as for selected cases of liver malignancy and ¡iver-site metabolic disorders. Neurological impairment is a major source of morbidity and moñality following OLT. Aim: To describe the incidence and the type of neurological complications occurring in the post-operative period of OLT in patients transplanted in our hospital. Material and methods: Between March 1994 and August 2007, 76 adult patients underwent OLT. Data on incidence, time of onset, and outcome of central nervous system (CNS) complications have been obtained from our program data base and patient charts. Results: Twenty three patients (30.3 percent) had CNS complications following OLT. The leading complications were immunosuppressive drug-related neurological impairment in nine patients (39.1 percent), peripheral nerve damage in five patients (21.7 percent), central pontine myelinolysis in four patients (17.4 percent), cerebrovascular disease in three (13 percent) and CNS infection in three (13 percent). Most CNS events (90 percent) occurred in the first 2 weeks after OLT. Five patients with neurological complications died (22 percent). Conclusions: CNS complications occurred in almost one fifth of the population studied, and they had a poor outcome, as previously reported).

ABSTRACT

BACKGROUND: Orthotopic liver transplantation (OLT) is the treatment of choice for multiple acute and chronic end-stage liver diseases as well as for selected cases of liver malignancy and liver-site metabolic disorders. Neurological impairment is a major source of morbidity and mortality following OLT. AIM: To describe the incidence and the type of neurological complications occurring in the post-operative period of OLT in patients transplanted in our hospital. MATERIAL AND METHODS: Between March 1994 and August 2007, 76 adult patients underwent OLT. Data on incidence, time of onset, and outcome of central nervous system (CNS) complications have been obtained from our program data base and patient charts. RESULTS: Twenty three patients (30.3%) had CNS complications following OLT. The leading complications were immunosuppressive drug-related neurological impairment in nine patients (39.1%), peripheral nerve damage in five patients (21.7%), central pontine myelinolysis in four patients (17.4%), cerebrovascular disease in three (13%) and CNS infection in three (13%). Most CNS events (90%) occurred in the first 2 weeks after OLT. Five patients with neurological complications died (22%). CONCLUSIONS: CNS complications occurred in almost one fifth of the population studied, and they had a poor outcome, as previously reported).
