RESUMEN

OBJECTIVE: To investigate the hypothesis that fetal abdominal circumference (AC) and uterine artery (UtA) Doppler pulsatility index (PI) could be used to select two homogeneous subgroups of women affected by hypertensive disorders of pregnancy (HDP), characterized by the coexistence of maternal hypertension with and without intrauterine growth restriction (IUGR). METHODS: This was a multicenter retrospective study of cases affected by HDP in whom fetal AC and UtA-PI had been measured at admission to fetomaternal medicine units. Maternal characteristics, pregnancy complications and outcome were recorded. These data allowed us to model the characteristics of fetal growth in cases affected by HDP, and to design composite indicators of risk factors for maternal metabolic syndrome and of severity for maternal functional organ damage. RESULTS: Measurements of fetal AC and UtA-PI allowed us to define a group of HDP cases with appropriate-for-gestational-age (AGA) fetuses (HDP-AGA), diagnosed by normal fetal AC and UtA-PI (n = 205), and a group of HDP cases with IUGR fetuses (HDP-IUGR), diagnosed by fetal AC < 5(th) centile and UtA-PI > 95(th) centile (n = 124). Curves fitted to the birth weights of these two groups were significantly different, but gestational age at admission for HDP (< 34 or ≥ 34 weeks) did not show an independent association with birth weight. When birth weight was expressed as a Z-score with respect to local reference charts, the average corresponded to the 6(th) and 48(th) centiles, respectively. The occurrence of HDP-AGA (as compared with HDP-IUGR) was significantly associated with risk factors for maternal metabolic syndrome (odds ratio, 2.79 (95% CI, 1.57-4.97)), independent of gestational age. The same risk factors yielded non-significant odds ratios for the development of late-onset (vs early-onset) HDP. Women with HDP-IUGR had worse clinical outcomes. CONCLUSIONS: This study provides new information based on simple prenatal bedside examinations that might help to differentiate HDP-IUGR from HDP-AGA fetuses. These groups are associated with different fetal growth patterns and risk factors, independent of gestational age at onset of the disease. Copyright © 2015 ISUOG.

RESUMEN

Allogeneic hematopoietic SCT (HSCT) increases the risk of hepatitis B virus (HBV) reactivation in hepatitis B surface antigen (HBsAg) carriers but the incidence, risk factors and course of HBV reactivation after HSCT in HBsAg-negative/anti-hepatitis B core antigen (anti-HBc)-positive recipients are not well known. A total of 50 HBsAg-negative/anti-HBc-positive HSCT recipients with onco-hematological diseases, underwent sequential clinical and laboratory examinations, including serum HBsAg, during follow-up. Serum HBV DNA collected at HSCT was retrospectively amplified by a sensitive PCR assay. During 17 months of follow-up, six (12%) patients had seroreverted to HBsAg, 7-32 months after HSCT, with 1- and 5-year cumulative rates of 13 and 22%. HBsAg seroreversion was associated with serum HBeAg higher than 8 log10 copies per ml HBV DNA and a 1.5 to 36 fold increase of serum alanine aminotransferase leading to HBeAg-positive chronic hepatitis B in all patients. Patients with chronic onco-hematological disease and long-lasting immunosuppression following HSCT had a higher risk of HBsAg seroreversion independently of serum HBV DNA levels at HSCT. HBsAg-negative/anti-HBc-positive HSCT recipients with chronic onco-hematological disease carry a significant risk of HBsAg seroreversion and HBeAg-positive chronic hepatitis B, independently of serum levels of HBV DNA at transplantation.

RESUMEN

The anti-CD20 chimaeric monoclonal antibody Rituximab has recently been shown to induce significant clinical response in a proportion of patients with refractory chronic graft-versus-host disease (cGVHD). We now report 38 patients, median age 48 years (22-61), receiving Rituximab for refractory cGVHD, assessed for clinical response and survival. Median duration of cGVHD before Rituximab was 23 months (range 2-116), the median number of failed treatment lines was 3 (range 1 to > or =6) and the median follow-up after Rituximab was 11 months (1-88). Overall response rate was 65%: skin 17/20 (63%), mouth 10/21 (48%), eyes 6/14 (43%), liver 3/12 (25%), lung 3/8 (37.5%), joints 4/5, gut 3/4, thrombocytopaenia 2/3, vagina 0/2, pure red cell aplasia 0/1 and, myasthenia gravis 1/1. During the study period 8/38 died: causes of death were cGVHD progression (n=3), disease relapse (n=1), infection (n=3), sudden death (n=1). The actuarial 2 year survival is currently 76%. We confirm that Rituximab is effective in over 50% of patients with refractory cGVHD and may have a beneficial impact on survival.

RESUMEN

Indeterminate cell histiocytosis (ICH) is a proliferation of indeterminate CD1a+, CD68+, S100+ and CD207- dermal dendritic cells. We describe a 39-year-old man who developed diffuse ICH and, 6 years later, acute myeloblastic leukaemia (AML). He was treated with cyclophosphamide, etoposide and vinblastine until 2003. In August 2004, he presented dyspnoea, hyperpyrexia and infiltration of the lung parenchyma, compatible with an AML invasion, and died after a course of induction chemotherapy. Cytomorphology and immunophenotype analyses suggested an ICH clonal evolution. The leukaemogenic role of etoposide is discussed. ICH has previously been reported in association with B-cell malignancy, but only one case has shown systemic progression.

RESUMEN

The serum levels of some cytokines seem to correlate with outcome in Hodgkin's disease (HD) and may be helpful in formulating new and better prognostic systems. The aim of this study was to analyse the correlations between the serum levels of different cytokines and the clinico-hematological features suggestive of a worse prognosis. The study involved 31 pts with a "de novo" diagnosis of HD (median age: 30 yrs; M/F: 13/18; stage I/II vs III/IV: 19/12; B symptoms: 12; bulky disease and extranodal disease: 9). The serum levels of sCD30, TNFalpha, TNF receptor I and II, IL6, IL6 receptor, IL10, sICAM-1 were evaluated at diagnosis, and correlated with gender, age (< or =/> 30), stage (I-II vs III-IV), systemic symptoms, bulky disease, ESR ( or = 40), serum copper (< or =/> 170 microg/dL), WBC counts (< or =/> 15x10(9)/L), prognostic scores (PS) according to Hasenclever ( or = 2), and the presence of extranodal disease. Stages III/IV were associated with significantly higher levels of sCD30 and TNF-RI (p=0.03), systemic symptoms with significantly higher levels of sCD30, TNFalpha, IL6, TNF-RI (p=0.027, 0.03, 0.0005, 0.002), bulky disease with TNF-RI (p=0.03), high ESR with IL6 and TNF-RI (p=0.0011, 0.0001), high WBC counts with sCD30, IL6, TNF-RI (p=0.03, 0.002, 0.01), high serum copper with sCD30 and IL6 (p=0.05, 0.0004), higher PS with sCD30, IL6, TNF-RI (p=0.002, 0.0003, 0.005), extranodal disease with TNFalpha and IL6 (p=0.05, 0.01). It was possible to define cut-off levels for some cytokines (sCD30 > 33.15 U/mL, TNFalpha > 29.71 pg/mL, IL6 > 12.43 pg/mL, TNF-RI > 3.23 ng/mL, IL6-R > 57 ng/mL) that significantly correlate with systemic symptoms, higher disease stages, ESR, serum copper, WBC counts and PS. Our study shows that high sCD30, TNFalpha, IL6 and TNF-RI levels are associated with advanced disease or a worse prognostic score. In the context of multiparametric HD staging, cytokine evaluation may be useful for identifying candidates for more intensive therapies.

RESUMEN

With the aim of developing an effective therapy for heavily pretreated refractory MM outpatients, we evaluated the OPPEBVCAD regimen, a Hodgkin's disease-derived protocol that includes many drugs effective in MM administered in a sequential schedule. Twenty-two pts aged 42-72 years, with symptomatic highly-pretreated refractory (18 cases), or primary resistant MM (four cases. including two pts with plasma cell leukemia-PCL) received this therapy every 28 days (2-4 cycles, followed by a maintenance program). Therapeutic response (Chronic Leukemia-Myeloma Task Force criteria) and performance status (PS) and pain (W.H.O.) were evaluated. All of the pts were evaluable for response. There were 9 (40%) objective responses (OR: stabilization of blood counts and bone lesions, serum calcium normalization, 50% or more reduction in the concentration of serum monoclonal component (MC), 90% reduction in Bence-Jones proteinuria), 8 (36%) partial responses (PR: 25-50% reduction in serum MC), 1 no response or stable disease (NR), and 4 (18%) cases of progressive disease (PD). OR plus PR were 77%. Of the 4 primary resistant tumors (2 PCL and 2 MM), 2 achieved PR, 1 OR (a PCL case) and 1 progressed. Median survival was 15 months for responding pts (OR plus PR) and 4.5 months for non-responders (NR plus PD). PS and pain improved in 15 pts and did not change in 9. The most frequent side effects were cytopenias, with one drug related infective death. The OPPEBVCAD regimen proved to be an effective therapy for refractory relapsing or primary resistant MM: in responders (two-thirds of the pts), survival was prolonged by about 10 months. Its efficacy in anthracycline-treated pts, as well as the feasibility of using it on an outpatient basis without any continuous drug infusions, make this regimen a promising third line salvage therapy.
