Depletion of naive T cells using clinical grade magnetic CD45RA beads: a new approach for GVHD prophylaxis
2013
Depletion of naive T cells from donor leukapheresis products (LPs) aims at the reduction of alloreactivity, while preserving memory T-cell reactivity (for example, to pathogens). This study established the immunomagnetic depletion procedure under clean room conditions using CD45RA beads and analyzed LPs of six donors for cell composition and functional immune responses. CD45RA depletion resulted in 3.4-4.7 log (median 4.4) reduction of CD45RA(+) T cells, thereby eliminating naive and late effector T cells. B cells were also completely removed, whereas significant proportions of NK cells, monocytes and granulocytes persisted. CD45RA-depleted LPs contained effector and central memory CD4(+) a…
Increase of CCR7- CD45RA+ CD8 T cells (TEMRA) in Chronic Graft-versus-host Disease
2006
Among the late effects of hematopoietic stem cell transplantation (HSCT), chronic graft-vs-host disease (cGVHD) still remains as the major determinant of long-term outcome and quality of life. The disease typically appears between 3 months to 1.5 years following an allogeneic transplantation and is characterized by symptoms similar to those of autoimmune disease.
Reduced interhemispheric structural connectivity between anterior cingulate cortices in borderline personality disorder
2008
Functional and structural alterations of the anterior cingulate cortex (ACC), a key region for emotional and cognitive processing, are associated with borderline personality disorder (BPD). However, the interhemispheric structural connectivity between the left and right ACC and between other prefrontal regions in this condition is unknown. We acquired diffusion-tensor imaging data from 20 healthy women and 19 women with BPD and comorbid attention-deficit hyperactivity disorder (ADHD). Interhemispheric structural connectivity between both sides of the ACC, dorsolateral prefrontal cortices and medial orbitofrontal cortices was assessed by a novel probabilistic diffusion tensor-based fiber tra…
Pharmacokinetics of Oral Posaconazole in Allogeneic Hematopoietic Stem Cell Transplant Recipients with Graft-versus-Host Disease
2007
Study Objective. To analyze the pharmacokinetics of posaconazole administered as prophylaxis for invasive fungal infections in recipients of hematopoietic stem cell transplants (HSCTs) who have graft-versus-host disease (GVHD). Design. Pharmacokinetic analysis in a subset of posaconazole-treated patients from a large, multicenter, phase III, randomized, double-blind, double-dummy, parallel-group trial that compared posaconazole with fluconazole. Setting. Ninety international medical centers. Patients. The subset of patients comprised 246 HSCT recipients for whom pharmacokinetic data were available. Intervention. All patients received posaconazole 200 mg oral suspension 3 times/day for a max…
Elevated Pressure in the Dorsal Part of Pancreas Divisum
1988
Summary In 6 patients with upper abdominal pain of unknown origin presenting with pancreas divisum, the pressure in the pancreatic duct was measured via the minor papilla into which in these patients the main part of the pancreatic duct system drains. For comparison intraductal manometry via the major papilla (papilla of Vater) was performed in 8 patients with normal pancreatic duct system. The pressure in the pancreatic duct of the control group was 10.5 ± 0.9 mm Hg. whereas in the patients with pancreas divisum it was 23.7 ± 1.3 mm Hg. The results demonstrate that in patients with pancreas divisum, intraductal pressure may be largely increased even in the fasting state.
Extensive clinical experience: relative prevalence of different androgen excess disorders in 950 women referred because of clinical hyperandrogenism.
2005
CONTEXT: We undertook this study to estimate the prevalence of the various androgen excess disorders using the new criteria suggested for the diagnosis of polycystic ovary syndrome (PCOS). SETTING: The study was performed at two endocrine departments at the University of Palermo (Palermo, Italy). PATIENTS: The records of all patients referred between 1980 and 2004 for evaluation of clinical hyperandrogenism were reevaluated. All past diagnoses were reviewed using the actual diagnostic criteria. To be included in this study, the records of the patients had to present the following available data: clinical evaluation of hyperandrogenism, body weight and height, testosterone (T), free T, dehyd…
Pituitary-adrenal responses to corticotropin-releasing factor in late onset 21-hydroxylase deficiency
1990
Intravenous corticotropin-releasing factor (CRF) and adrenocorticotropin hormone (ACTH) were administered in patients with adult onset 21-hydroxylase deficiency to compare their diagnostic capability as well as to investigate hypothalamic-pituitary-adrenal function in this disorder. Responses of 17-hydroxyprogesterone, which were markedly elevated compared with controls, were identical with CRF and ACTH. However, intravenous ACTH resulted in higher androstenedione levels in comparison to CRF. Adrenocorticotropin hormone also resulted in decreased cortisol responses, confirming a defect in steroidogenesis, a finding that was not evident with CRF. Plasma ACTH responses to CRF were similar in …
Ovine corticotropin-releasing factor and dexamethasone responses in hyperandrogenic women
1990
Eighteen hyperandrogenic, hirsute women received ovine corticotropin-releasing factor (CRF; 1 microgram/kg) as well as a dexamethasone (DEX) suppression test. Nine of the 18 hirsute women exhibited increased DEX sensitivity. Plasma adrenocorticotropic hormone (ACTH) responses after ovine CRF were significantly lower in the DEX-sensitive subgroup, but serum androstenedione was higher. Baseline serum androgen levels could not predict DEX responses. A significant negative correlation existed between the suppression of androgens after DEX and the increase in ACTH after ovine CRF. The suppression of androgen correlated with the ratio of the increase in androgen to the increase in ACTH after ovin…
Physiological Estrogen Replacement May Enhance the Effectiveness of the Gonadotropin-Releasing Hormone Agonist in the Treatment of Hirsutism
1994
GnRH agonists (GnRH-A) have been used for the treatment of hirsutism in women with ovarian hyperandrogenism. However, significant side-effects, including vasomotor symptoms and bone loss, have prevented the long term use of this therapy. In this study, we evaluated the effects of low dose (physiological) estrogen replacement on the side-effects and clinical and hormonal parameters of 22 hirsute women with ovarian hyperandrogenism when treated with a long-acting GnRH-A, Decapeptyl. Ten patients with Ferriman-Gallwey (FG) scores averaging 13.4 +/- 1.5 were randomly assigned to be treated with Decapeptyl alone (3.75 mg, im, every 28 days for 6 months), and 12 other patients with FG scores aver…
The endocrine pattern of late onset adrenal hyperplasia (21-hydroxylase deficiency)
1984
We describe 5 adult women with severe hirsutism due to late onset 21-hydroxylase deficiency. Diagnosis was performed on the finding of high serum 17-hydroxyprogesterone (17OHP) levels with a marked hyperresponse to an ACTH test. The endocrine study showed in most patients a gonadotropin behavior similar to that observed in classical polycystic ovary (PCO) syndrome. Prolactin levels were slightly increased in basal conditions and presented an exaggerated response to TRH stimulation.
