Autotransplant for Hodgkin lymphoma after failure of upfront BEACOPP escalated (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine and prednisone)

BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine and prednisone) escalated is the preferred upfront Hodgkin lymphoma (HL) treatment in a number of countries. Upon failure, high-dose chemotherapy with autologous stem cell support (HDT/ASCT) is performed, but its effectiveness has not been verified in this setting. We analyzed all Swiss cases of chemosensitive HL autografted after failure of BEACOPP escalated (n = 22) and compared outcomes with 22 cases of HDT/ASCT following frontline ABVD (doxorubicin, bleomycin, vinblastine and dacarbazine) failure. Five-year progression-free survival (PFS) was 76% for ABVD and 42% for BEACOPP escalated (p = 0.029). Two- and 5-year overall survival (OS) was 90% and 71% for ABVD and 72% and 65% for BEACOPP escalated, respectively (p = not significant). Three patients in the ABVD and four in the BEACOPP escalated groups underwent allotransplant for relapse after HDT/ASCT. Grade 3-4 toxicities were comparable in both groups. Three cases of therapy-related myelodysplastic syndrome/acute myeloid leukemia (t-MDS/t-AML) were recorded in the BEACOPP escalated group. The acceptable PFS and OS of chemosensitive patients with HL autografted after failure of upfront BEACOPP escalated seem to justify this approach.

The multicenter trial SAKK 37/95 of cladribine, cyclophosphamide and prednisone in the treatment of chronic lymphocytic leukemias and low-grade non-Hodgkin's lymphomas

A multicenter trial was performed to confirm the therapeutic efficacy and the toxicity profile of the combination of cladribine, cyclophosphamide and prednisone in low-grade non-Hodgkin's lymphoma (NHL) and chronic lymphocytic leukemia (CLL). Twenty-three adults with previously treated (61%) or untreated (39%) NHL International Working Formulation A or Binet B and C CLL were administered cladribine 0.1 mg/kg/day as a subcutaneous bolus for 5 days, intravenous cyclophosphamide 500 mg/m2 on day 1, and oral prednisone 40 mg/m2 on days 1-5, every 4 weeks. Unexpected early hematological toxicities led to dose modifications for pretreated patients who received cladribine for 3 days only up to a maximum of five courses. Responses were observed in 75%, with 7 patients obtaining a complete clinical and hematological response. Median duration of complete response was 9 months. Median time to progression or relapse was 31 months. Myelosuppression and infections were dose limiting whereas posttreatment complications, including fatalities, resulted from infections. Median overall survival time from trial entry was 60 months. Activity of the combination of cladribine, cyclophosphamide and prednisone was confirmed. However, in the specific setting of a multicenter trial, unexpected fatal infectious episodes occurred in pretreated patients. Great caution is thus required in these susceptible patients and the routine use of corticosteroids should probably be abandoned.

Changes in bone mineral density over 18 months following kidney transplantation: the respective roles of prednisone and parathyroid hormone

Prednisone is a major factor of bone loss after kidney transplantation. The role of hyperparathyroidism and immunosuppressors is less clear.

Effects of deflazacort versus prednisone on bone mass, body composition, and lipid profile: a randomized, double blind study in kidney transplant patients

To compare the effects of deflazacort (DEFLA) vs. prednisone (PRED) on bone mineral density (BMD), body composition, and lipids, 24 patients with end-stage renal disease were randomized in a double blind design and followed 78 weeks after kidney transplantation. BMD and body composition were assessed using dual energy x-ray absorptiometry. Seventeen patients completed the study. Glucocorticosteroid doses, cyclosporine levels, rejection episodes, and drop-out rates were similar in both groups. Lumbar BMD decreased more in PRED than in DEFLA (P < 0.05), the difference being particularly marked after 24 weeks (9.1 +/- 1.8% vs. 3.0 +/- 2.4%, respectively). Hip BMD decreased from baseline in both groups (P < 0.01), without intergroup differences. Whole body BMD decreased from baseline in PRED (P < 0.001), but not in DEFLA. Lean body mass decreased by approximately 2.5 kg in both groups after 6-12 weeks (P < 0.001), then remained stable. Fat mass increased more (P < 0.01) in PRED than in DEFLA (7.1 +/- 1.8 vs. 3.5 +/- 1.4 kg). Larger increases in total cholesterol (P < 0.03), low density lipoprotein cholesterol (P < 0.01), lipoprotein B2 (P < 0.03), and triglycerides (P = 0.054) were observed in PRED than in DEFLA. In conclusion, using DEFLA instead of PRED in kidney transplant patients is associated with decreased loss of total skeleton and lumbar spine BMD, but does not alter bone loss at the upper femur. DEFLA also helps to prevent fat accumulation and worsening of the lipid profile.

Combining Enzalutamide with Abiraterone, Prednisone, and Androgen Deprivation Therapy in the STAMPEDE Trial.

There are compelling reasons to study the addition of both enzalutamide and abiraterone, in combination, to standard-of-care for hormone-naïve prostate cancer. Through a protocol amendment, this will be assessed in the STAMPEDE trial, with overall survival as primary outcome measure.

Adjunct prednisone therapy for patients with community-acquired pneumonia: a multicentre, double-blind, randomised, placebo-controlled trial

BACKGROUND Clinical trials yielded conflicting data about the benefit of adding systemic corticosteroids for treatment of community-acquired pneumonia. We assessed whether short-term corticosteroid treatment reduces time to clinical stability in patients admitted to hospital for community-acquired pneumonia. METHODS In this double-blind, multicentre, randomised, placebo-controlled trial, we recruited patients aged 18 years or older with community-acquired pneumonia from seven tertiary care hospitals in Switzerland within 24 h of presentation. Patients were randomly assigned (1:1 ratio) to receive either prednisone 50 mg daily for 7 days or placebo. The computer-generated randomisation was done with variable block sizes of four to six and stratified by study centre. The primary endpoint was time to clinical stability defined as time (days) until stable vital signs for at least 24 h, and analysed by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00973154. FINDINGS From Dec 1, 2009, to May 21, 2014, of 2911 patients assessed for eligibility, 785 patients were randomly assigned to either the prednisone group (n=392) or the placebo group (n=393). Median time to clinical stability was shorter in the prednisone group (3·0 days, IQR 2·5-3·4) than in the placebo group (4·4 days, 4·0-5·0; hazard ratio [HR] 1·33, 95% CI 1·15-1·50, p<0·0001). Pneumonia-associated complications until day 30 did not differ between groups (11 [3%] in the prednisone group and 22 [6%] in the placebo group; odds ratio [OR] 0·49 [95% CI 0·23-1·02]; p=0·056). The prednisone group had a higher incidence of in-hospital hyperglycaemia needing insulin treatment (76 [19%] vs 43 [11%]; OR 1·96, 95% CI 1·31-2·93, p=0·0010). Other adverse events compatible with corticosteroid use were rare and similar in both groups. INTERPRETATION Prednisone treatment for 7 days in patients with community-acquired pneumonia admitted to hospital shortens time to clinical stability without an increase in complications. This finding is relevant from a patient perspective and an important determinant of hospital costs and efficiency.

Chickenpox is not always benign: postvaricella purpura fulminans requires prompt and aggressive treatment

We present 2 patients, who were admitted owing to rapidly progressing purpuric lesions due to postvaricella purpura fulminans, a coagulopathy leading to life- or limb-threatening thrombosis caused by a severe transient autoimmune protein S deficiency. Laboratory results were being consistent with disseminated intravascular coagulation secondary to protein S deficiency; treatment with fresh frozen plasma, intravenous immunoglobulins, and prednisone was started. In our experience, a prompt therapy may limit the course and the extent of the disease. We present a review of the topic with supporting literature for the therapeutic options. Therefore, we should be reminded that purpura fulminans is a rare but severe complication of chickenpox, which demands quick action.

Rapid induction of remission in large vessel vasculitis by IL-6 blockade. A case series

OBJECTIVE: To evaluate the effect of IL-6 blockade using tocilizumab in inducing remission of arterial large vessel vasculitides (LVV). METHODS: Five consecutive patients with giant-cell arteritis (GCA) and two with Takayasu’s arteritis (TA) were treated by tocilizumab infusions (8 mg/kg). Tocilizumab was given every other week for the first month and once monthly thereafter. Clinical symptoms of disease activity, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) level and glucocorticoid (GC) dosage necessary to maintain remission were prospectively assessed. MR angiography was performed to monitor local inflammation. RESULTS: Of the seven patients three were newly diagnosed and four showed GC resistance, i.e. GC could not be lowered to less than 7.5 mg/day. The mean follow-up time was 4.3 months (range 3–7 months). All patients achieved a rapid and complete clinical response and normalisation of the acute phase proteins. Remarkably, prednisone dosage could be reduced within 12 weeks to a mean of 2.5 mg/day (range 0–10 mg/day). No relapse and no drug-related side effects were noted. CONCLUSION: Collectively the data suggest that IL-6 blockade using tocilizumab qualifies as a therapeutic option to induce rapid remission in large vessel vasculitides.

[Glomerulonephritis and vasculitis as causes of arterial hypertension]

The various types of glomerulonephritis, including many forms of vasculitis, are responsible for about 15% of cases of end-stage renal disease (ESRD). Arterial hypertension represents a frequent finding in patients suffering from glomerulonephritis or vasculitis and hypertension also serves as an indicator for these severe types of diseases. In addition, there are symptoms and signs like hematuria, proteinuria and renal failure. Especially, rapidly progressive glomerulonephritis (RPGN) constitutes a medical emergency and must not be missed by treating physicians. This disease can either occur limited to the kidneys or in the context of a systemic inflammatory disorder, like a vasculitis. If left untreated, RPGN can lead to a necrotizing destruction of glomeruli causing irreversible kidney damage within several months or even weeks. With respect to the immunologically caused vasculitis, there are - depending upon the severity and type of organ involved - many clinical warning signs to be recognized, such as arterial hypertension, hemoptysis, arthalgias, muscle pain, palpable purpura, hematuria, proteinuria and renal failure. In addition, constitutional signs, such as fever and loss of body weight may occur concurrently. Investigations of glomerulonephritis or vasculitis must contain a careful and complete examination of family history and medications used by the respective patient. Thereafter, a thorough clinical examination must follow, including skin, joints and measurement of arterial blood pressure. In addition, a spectrum of laboratory analyses is required in blood, such as full blood screen, erythrocyte sedimentation rate, CRP, creatinine, urea and glucose, and in urine, including urinalysis looking for hematuria, red cell casts and proteinuria. Importantly, proteinuria needs to be quantified by the utilization of a random urine sample. Proteinuria > 3g/d is diagnostic for a glomerular damage. These basic tests are usually followed by more specialized analyses, such as a screening for infections, including search for HIV, hepatitis B or C and various bacteria, and for systemic inflammatory diseases, including tests for antibodies, such as ANA, anti-dsDNA, ANCA, anti-GBM and anti-CCP. In cases of membranous nephropathy, antibodies against phospholipase-A2-receptor need to be looked for. Depending upon the given clinical circumstances and the type of disease, a reasonable tumor screening must be performed, especially in cases of membranous and minimal-change nephropathy. Finally, radiological examinations will complete the initial work-up. In most cases, at least an ultrasound of the kidney is mandatory. Thereafter, in most cases a renal biopsy is required to establish a firm diagnosis to define all treatment options and their chance of success. The elimination of a specific cause for a given glomerulonephritis or vasculitis, such as an infection, a malignancy or a drug-related side-effect, remains the key principle in the management of these diseases. ACE-inhibitors, angiotensin receptor-blockers, aldosteron antagonists and renin-inhibitors remain the mainstay in the therapy of arterial hypertension with proteinuria. Only in cases of persistently high proteinuria, ACE-inhibitors and angiotensin receptor blockers can be prescribed in combination. Certain types of glomerulonephritis and essentially all forms of vasculitis require some form of more specific anti-inflammatory therapy. Respective immunosuppressive drug regimens contain traditionally medications, such as glucocorticoids (e. g. prednisone), cyclosporine A, mycophenolate mofetil, cyclophosphamide, and azathioprine. With respect to more severe forms of glomerulonephritis and vasculitis, the antibody rituximab represents a new and less toxic alternative to cyclophosphamide. Finally, in certain special cases, like Goodpasture's syndrome or severe ANCA-positive vasculitis, a plasma exchange will be useful and even required.

Acquired factor XIII deficiency: a therapeutic challenge

Less than 60 cases of acquired factor (F)XIII deficiencies have been reported, most having distinct clinical features. To illustrate the therapeutic challenges of acquired FXIII inhibitors, we report a case of a 65-year-old patient with no previous bleeding history who suddenly developed massive haemorrhages associated to a strong and isolated FXIII inhibitor. No underlying disorder has been detected till now after three years of follow-up. Despite aggressive treatment with prednisone, rituximab, cyclophosphamide, immunoglobulin, immunoadsorption and immune tolerance his inhibitor is still present, although at low titre and with a clinical benefit since the patient has no more bleed since more than one year. Moreover the patient had a venous thromboembolic complication. After a review of the management of acquired FXIII deficiency patients and based on the management of acquired haemophilia we discuss a possible strategy for such difficult cases.

Osseointegration of hollow cylinder based spinal implants in normal and osteoporotic vertebrae: a sheep study

INTRODUCTION: Osteoporosis is not only responsible for an increased number of metaphyseal and spinal fractures but it also complicates their treatment. To prevent the initial loosening, we developed a new implant with an enlarged implant/bone interface based on the concept of perforated, hollow cylinders. We evaluated whether osseointegration of a hollow cylinder based implant takes place in normal or osteoporotic bone of sheep under functional loading conditions during anterior stabilization of the lumbar spine. MATERIALS AND METHODS: Osseointegration of the cylinders and status of the fused segments (ventral corpectomy, replacement with iliac strut, and fixation with testing implant) were investigated in six osteoporotic (age 6.9 +/- 0.8 years, mean body weight 61.1 +/- 5.2 kg) and seven control sheep (age 6.1 +/- 0.2 years, mean body weight 64.9 +/- 5.7 kg). Osteoporosis was introduced using a combination protocol of ovariectomy, high-dose prednisone, calcium and phosphor reduced diet and movement restriction. Osseointegration was quantified using fluorescence and conventional histology; fusion status was determined using biomechanical testing of the stabilized segment in a six-degree-of-freedom loading device as well as with radiological and histological staging. RESULTS: Intact bone trabeculae were found in 70% of all perforations without differences between the two groups (P = 0.26). Inside the cylinders, bone volume/total volume was significantly higher than in the control vertebra (50 +/- 16 vs. 28 +/- 13%) of the same animal (P<0.01), but significantly less (P<0.01) than in the near surrounding (60 +/- 21%). After biomechanical testing as described in Sect. "Materials and methods", seven spines (three healthy and four osteoporotic) were classified as completely fused and six (four healthy and two osteoporotic) as not fused after a 4-month observation time. All endplates were bridged with intact trabeculae in the histological slices. CONCLUSIONS: The high number of perforations, filled with intact trabeculae, indicates an adequate fixation; bridging trabeculae between adjacent endplates and tricortical iliac struts in all vertebrae indicates that the anchorage is adequate to promote fusion in this animal model, even in the osteoporotic sheep.

Six-year follow-up of azathioprine and mycophenolate mofetil use during the first 6 months of renal transplantation

Long-term follow-up examination to test whether therapy with mycophenolate mofetil (MMF) or azathioprine (AZA) during the first year translates into different graft or patient survival and graft function is important. Therefore, 6-year follow-up data of a group of 80 consecutive renal transplant recipients were analyzed. The first group of 40 patients was treated with AZA, cyclosporine and prednisone and the second group with MMF, cyclosporine and prednisone for the first 6 months. Graft failure rates were compared during follow-up. Creatinine, inverse slope of creatinine (delta/creatinine) and 24-hour proteinuria at 6 years post transplantation were compared. The Kaplan-Meier analyses for death-censored and non-censored graft failure showed no difference between the groups. Creatinine values at 6 years for the AZA Group were 139 +/- 36 micromol/l (95% CI 125.9-151.2 micromol/l) and for the MMF Group 149 +/- 52 micromol/l (95% CI 133.9-164.9 micromol/l). Delta/creatinine and 24-hour proteinuria at 6 years did not differ between the two groups. We conclude that an initial 6-month treatment with MMF as opposed to AZA reduced the early rejection rate, but did not result in superior long-term graft function or survival after 6 years of follow-up observation.

[Hyperinsulinemia as a consequence of systemic venous drainage in patients with pancreas transplantation]

To evaluate the metabolic consequences of pancreatic transplantation with systemic venous drainage on beta cell function, we examined insulin and C-peptide responses to arginine and secretin in type I diabetic recipients of pancreas transplantation (n = 16), and normal controls (n = 28). Basal insulin levels were 24 +/- 3 microU/l in pancreas recipients, and 7 +/- 1 microU/l in controls (p less than 0.001). Stimulated insulin levels following arginine (MANOVA, p less than 0.001), and secretin (MANOVA, p less than 0.001) were 1.5 to 3 fold elevated compared to controls. In contrast, integrated C-peptide responses following stimulation with arginine or secretin did not differ significantly between the two groups. We conclude that recipients of pancreas allografts with systemic venous drainage have elevated basal and stimulated insulin levels and that these alterations are primarily due to alterations of first pass hepatic insulin clearance although insulin resistance secondary to immunosuppressive therapy (including prednisone) may also play a contributing role. To avoid hyperinsulinemia and its possible long term adverse consequences, transplantation of pancreas allografts in sites with portal rather than systemic venous drainage may be preferable.

Systemic venous drainage of pancreas allografts as independent cause of hyperinsulinemia in type I diabetic recipients

To evaluate the metabolic consequences of pancreas transplantation with systemic venous drainage on beta-cell function, we examined insulin and C-peptide responses to glucose and arginine in type I (insulin-dependent) diabetic pancreas recipients (n = 30), nondiabetic kidney recipients (n = 8), and nondiabetic control subjects (n = 28). Basal insulin levels were 66 +/- 5 pM in control subjects, 204 +/- 18 pM in pancreas recipients (P less than 0.0001 vs. control), and 77 +/- 17 pM in kidney recipients. Acute insulin responses to glucose were 416 +/- 44 pM in control subjects, 763 +/- 91 pM in pancreas recipients (P less than 0.01 vs. control), and 589 +/- 113 pM in kidney recipients (NS vs. control). Basal and stimulated insulin levels in two pancreas recipients with portal venous drainage were normal. Integrated acute C-peptide responses were not statistically different (25.3 +/- 4.3 nM/min in pancreas recipients, 34.2 +/- 5.5 nM/min in kidney recipients, and 23.7 +/- 2.1 nM/min in control subjects). Similar insulin and C-peptide results were obtained with arginine stimulation, and both basal and glucose-stimulated insulin-C-peptide ratios in pancreas recipients were significantly greater than in control subjects. We conclude that recipients of pancreas allografts with systemic venous drainage have elevated basal and stimulated insulin levels and that these alterations are primarily due to alterations of first-pass hepatic insulin clearance, although insulin resistance secondary to immunosuppressive therapy (including prednisone) probably plays a contributing role. To avoid hyperinsulinemia and its possible long-term adverse consequences, transplantation of pancreas allografts into sites with portal rather than systemic venous drainage should be considered.

Fatal sepsis in an AIDS patient during therapy for Pneumocystis carinii pneumonia

The case of a patient with a newly diagnosed HIV infection and Pneumocystis carinii pneumonia is presented. Despite treatment with high-dose trimethoprim/sulfamethoxazole (TMP/SMX) and prednisone with initial improvement, the patient acutely deteriorated with severe acidosis and died on the 4th day of hospitalization. Cryptococcus neoformans grew the next day in broncheoalveolar lavage (BAL) and blood culture. As simultaneous presence of more than one opportunistic infection can occur in these patients, systematic workup for other common opportunistic infections must be performed.
