Successful Pregnancies in Kidney Transplant Recipients: Experience of the National Kidney Transplant Program From Uruguay.

BACKGROUND: Renal transplantation increases the possibilities of pregnancy in women of reproductive age. The course of pregnancy was analyzed retrospectively in patients with kidney or kidney-pancreas transplant, surveying maternal-fetal or renal graft complications and the relation with pre-pregnancy renal function. METHODS: A cohort that includes all the kidney transplant recipients who went through pregnancy in Uruguay in a period of 28 years is described. Forty pregnancies in 32 patients were registered; the average time between the kidney transplant and the beginning of the gestation period was 47 months. From the total gestations, 10 abortions, 1 neonatal death, and 1 fetal demise were registered. From the remaining pregnancies, we highlight prematurity (18/29) and low birth weight (14/21). Twenty-nine in 30 pregnancies ended in cesarean section; in 8 of 30, pre-eclampsia diagnosis was performed. Acute rejection was diagnosed in 2 of 30 pregnancies, both undergoing their first post-transplant year. RESULTS: Two patients required dialysis throughout the pregnancy because of progress into severe renal insufficiency. Higher obstetric perinatal morbidity and renal function deterioration was related to lower pre-pregnancy glomerular filtration rate (GFR). CONCLUSIONS: A successful pregnancy is possible in transplant recipients, yet there are risks of prematurity, low birth weight, and abortion. A lower GFR before pregnancy was associated with poorer maternal and perinatal results as shown in the different series.

Nephropathy associated with antiphospholipid antibodies in patients with systemic lupus erythematosus.

BACKGROUND: Nephropathy associated with antiphospholipid antibodies (aPL) has been proposed as a risk factor of worse renal prognosis in patients with systemic lupus erythematosus (SLE). The purpose of the current study was to evaluate the prevalence of aPL-associated nephropathy (aPLN) among patients with lupus nephritis and to describe their functional renal outcome. METHODS: A total of 79 renal biopsies from 77 patients followed at the Hospital Clinic, Spain were analysed. Each renal biopsy was evaluated by a pathologist who was blinded to the aPL status. Thrombotic microangiopathy (TMA), fibrous intimal hyperplasia (FIH), fibrocellular arterial occlusion (FAO), focal cortical atrophy (FCA), and tubular thyroidization as lesions suggestive of aPLN were identified. RESULTS: aPLN was found in nine (11.4%) biopsies. TMA was found in three (33.3%) cases whereas chronic aPLN, represented by FIH and FCA, was found in four (44.4%) and three (33.3%) cases, respectively. A significant association between the presence of aPL and aPLN was found (p = 0.003). Patients with lupus anticoagulant (LA) plus IgG anticardiolipin antibodies (aCL) showed an increased prevalence of aPLN (OR: 3.61, 95% CI 1.28-5.14; p = 0.002). Creatinine levels were significantly increased in patients with aPLN compared with those with aPL without aPLN (p = 0.038). However, no significant difference in complete remission, partial remission, not response, and established renal damage between groups was observed at the end of follow-up. CONCLUSIONS: The aPL have an important role in the pathogenesis of renal lesions in SLE patients. Prospective studies are needed to address the role of aPLN in the long-term outcome of SLE patients with positive aPL.

Primeros casos autóctonos de hepatitis e en Uruaguay / First autochthonous hepatitis E cases in Uruguay

Con el objetivo de describir los primeros casos autóctonosde Hepatitis E se realizó un estudio descriptivo. La población,9 enfermos, se identificó en el periodo noviembre 2009a julio 2010. Se seleccionaron por IgG e IgM específicaspara VHE y se realizó búsqueda de ARN viral en suero porRT-PCR. Presentaron una media de 51 años, 8 del sexo masculino, educación terciaria, nivel socioeconómico medio alto, atención en el sector privado y residencia urbana. La clínica fue similar a Hepatitis A, con transaminasas elevadas por encima de 1500 (mU/ml), la glutamicopiruvica convalores máximos de 5270 (mU/ml). Todos presentaron hiperbilirrubinemia a predominio directa, aumento de lagamaglutamil transferasa y de Fosfatasa Alcalina. Se demostrócirculación en Uruguay del VHE con manifestaciones clínicas, lo que traduce la presencia de una enfermedad emergente. Se plantea introducir el diagnostico del VHE en forma protocolizada en pacientes sin diagnostico etiológico de hepatitis.

In order to describe the first autochthonous Hepatitis E cases, we carried out a descriptive study. The population, 9 patients, was identified from November 2009 to July 2010. They were selected by specificIgG and IgM for HEV and we made viral RNA search in serum by RT-PCR. Patients average age was 51 years old, 8 male, tertiary education, upper middle socioeconomic level, health attention in private sector and urban residence. Clinic results similar to hepatitis A, with elevated transaminases over 1500 (mU/ml) and glutamic pyruvic with maximum values of 5270 (mU/ml). All patients presented hyperbilirubinemia (direct predominance) and increased gamma glutamyl transferase and alkaline phosphatase. Circulation of HEV with clinical manifestations was demonstrated in Uruguay, this showsthe presence of an emergent disease. We suggest introducing a formalized HEV diagnosis in patients without etiologic diagnosis of hepatitis.

Validation of the Spanish, Portuguese and French versions of the Lupus Damage Index questionnaire: data from North and South America, Spain and Portugal.

We have previously developed and validated a self-administered questionnaire, modelled after the Systemic Lupus International Collaborating Clinics Damage Index (SDI), the Lupus Damage Index Questionnaire (LDIQ), which may allow the ascertainment of this construct in systemic lupus erythematosus (SLE) patients followed in the community and thus expand observations made about damage. We have now translated, back-translated and adapted the LDIQ to Spanish, Portuguese and French and applied it to patients followed at academic and non-academic centres in North and South America, Portugal and Spain while their physicians scored the SDI. A total of 887 patients (659 Spanish-speaking, 140 Portuguese-speaking and 80 French-speaking patients) and 40 physicians participated. Overall, patients scored all LDIQ versions higher than their physicians (total score and all domains). Infrequent manifestations had less optimal clinimetric properties but overall agreement was more than 95% for the majority of items. Higher correlations were observed among the Spanish-speaking patients than the Portuguese-speaking and French-speaking patients; further adjustments may be needed before the Portuguese and French versions of the LDIQ are applied in community-based studies. The relationship between the LDIQ and other outcome parameters is currently being investigated in a different patient sample.
