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.

Hereditary angioedema (HAE) in children and adolescents--a consensus on therapeutic strategies

Hereditary angioedema due to C1 inhibitor (C1 esterase inhibitor) deficiency (types I and II HAE-C1-INH) is a rare disease that usually presents during childhood or adolescence with intermittent episodes of potentially life-threatening angioedema. Diagnosis as early as possible is important to avoid ineffective therapies and to properly treat swelling attacks. At a consensus meeting in June 2011, pediatricians and dermatologists from Germany, Austria, and Switzerland reviewed the currently available literature, including published international consensus recommendations for HAE therapy across all age groups. Published recommendations cannot be unconditionally adopted for pediatric patients in German-speaking countries given the current approval status of HAE drugs. This article provides an overview and discusses drugs available for HAE therapy, their approval status, and study results obtained in adult and pediatric patients. Recommendations for developing appropriate treatment strategies in the management of HAE in pediatric patients in German-speaking countries are provided.Conclusion Currently, plasma-derived C1 inhibitor concentrate is considered the best available option for the treatment of acute HAE-C1-INH attacks in pediatric patients in German-speaking countries, as well as for short-term and long-term prophylaxis.

Therapeutic approaches to patients with hypereosinophilic syndromes

Hypereosinophilic syndromes (HES) are a heterogeneous group of disorders that range from asymptomatic eosinophilia > 1,500/mL to aggressive disease complicated by life-threatening end organ involvement, including endomyocardial fibrosis and thromboembolism. To complicate matters further, similar clinical manifestations can occur in the setting of marked eosinophilia due to helminth infection, drug hypersensitivity, and other causes. In the past, therapy was guided only by the exclusion of these secondary causes of eosinophilia and the severity of the clinical manifestations. More recently, the availability of novel targeted therapies and a better understanding of the etiologies of some subtypes of HES have necessitated a more structured approach.

Cost-effectiveness of 12-month therapeutic assertive community treatment as part of integrated care versus standard care in patients with schizophrenia treated with quetiapine immediate release (ACCESS trial)

To compare the 1-year cost-effectiveness of therapeutic assertive community treatment (ACT) with standard care in schizophrenia. ACT was specifically developed for patients with schizophrenia, delivered by psychosis experts highly trained in respective psychotherapies, and embedded into an integrated care system.

Impact of genetic SLC28 transporter and ITPA variants on ribavirin serum level, hemoglobin drop and therapeutic response in patients with HCV infection

In the last decade, pegylated interferon-α (PegIFN-α) plus ribavirin (RBV) was the standard treatment of chronic hepatitis C for genotype 1, and it remains the standard for genotypes 2 and 3. Recent studies reported associations between RBV-induced anemia and genetic polymorphisms of concentrative nucleoside transporters such as CNT3 (encoded by SLC28A3) and inosine triphosphatase (encoded by ITPA). We aimed at studying genetic determinants of RBV kinetics, efficacy and treatment-associated anemia.

Post-surgical scalp wounds with exposed bone treated with a plant-derived wound therapeutic

To evaluate the efficacy of a plant-derived wound dressing, a mixture of hypericum oil (Hypericum perforatum) and neem oil (Azadirachta indica), in scalp wounds with exposed bone.

Endoscopy for repeatedly ingested sharp foreign bodies in patients with borderline personality disorder: an international survey

The general guidelines on the management of ingested foreign bodies (FBs) do not address specific aspects raised by psychiatric patients, particularly in patients with borderline personality disorders (BPD) who repeatedly ingest FBs. The aim of this survey was to collect data on experience and opinions on the management of FBs in psychiatric patients with BPD and to review the relevant literature.

Involvement of autophagy in the response of tumor cells to PtdIns3K inhibitors: therapeutic implications

The phosphoinositide 3-kinase (PI3K) pathway plays a crucial role in cell proliferation and survival and is frequently activated by genetic and epigenetic alterations in human cancer. An arsenal of pharmacological inhibitors of key signaling enzymes in this pathway, including class I(A) PI3K isoforms, has been developed in the past decade and several compounds have entered clinical testing in cancer patients. The PIK3CA/p110α isoform is the most studied enzyme of the family and a validated cancer target. The induction of autophagy by PI3K pathway inhibitors has been documented in various cancers, although a clear picture about the significance of this phenomenon is still missing, especially in the in vivo situation. A better understanding of the contribution of autophagy to the action of PI3K inhibitors on tumors cells is important, since it may limit or enhance the action of these compounds, depending on the cellular context.

Therapeutic hypothermia in term infants after perinatal encephalopathy: The last 5 years in Switzerland

Background: Therapeutic hypothermia (TH) following perinatal asphyxial encephalopathy in term infants improves mortality and neurodevelopmental outcome. In Europe, most neonatal units perform active cooling whereas in Switzerland passive cooling is predominantly used. Aims: (i) To determine how many infants were cooled within the last 5 years in Switzerland, (ii) to assess the cooling methods, (iii) to evaluate the variation of temperature of different cooling methods, and (iv) to evaluate the use of neuromonitoring. Study design: Retrospective cohort study. Patients: Notes of all cooled term infants between March 2005 and December 2010 in 9 perinatal and two paediatric intensive care centres were retrospectively reviewed. Active cooling was compared to passive cooling alone and to passive cooling in combination with gel packs. Results: 150 infants were cooled. Twenty-seven (18.2%) were cooled actively, 34 (23%) passively and 87 (58.8%) passively in combination with gel packs. Variation of temperature was significantly different between the three methods. Passive cooling had a significant higher variation of temperature (SD of 0.89) than both passive cooling in combination with gel packs (SD of 0.79) and active cooling (SD of 0.76). aEEG before TH was obtained in 35.8% of the infants and 86.5% had full EEG. One cUS was performed in 95.3% and MRI in 62.2% of the infants. Conclusion: Target temperature can be achieved with all three cooling methods. Passive cooling has the highest variation of temperature. Neuromonitoring should be improved in Swiss neonatal and paediatric intensive care units. Our results stress the importance of national registries.

[Oesophageal and fundic variceal bleeding]

Oesophageal and fundic varices belong to the most frequent complications of cirrhosis and portal hypertension. Due to their significant morbidity and mortality, bleedings from oesophageal or fundic varices represent a challenge for the emergency medical team as well as for the gastroenterologist. The patient with a variceal bleeding should be accurately monitored and his/her hemodynamic parameters should be maintained stable with the administration of plasma expanders and blood units when indicated. An antibiotic prophylaxis in this setting--norfloxacin or ceftriaxon--has been demonstrated to significantly reduce morbidity and mortality. Additionally, the early administration of vasoactive compounds, such as terlipressin, somatostatin or octreotide, is associated with beneficial effects in reducing the bleeding. An upper gastrointestinal endoscopy should be generally performed within the first twelve hours from the beginning of the bleeding in order to obtain an accurate diagnosis and to provide an adequate treatment. Endoscopic procedures to control the bleeding include the rubber band ligation, the treatment of the varix with a sclerosing agent or the injection of tissue glue into the varix. In case of recurrent bleeding, beyond the above methods, different techniques, such as the transjugular porto-caval shunt, surgical shunt procedures, as well as embolisation of splanchnic blood vessels, represent additional therapeutic options. However, they are associated with very high mortality rates and their indication has to be discussed case by case by an interdisciplinary team of experts. Future therapies include the optimisation and the improvement of the current medical and endoscopic armamentarium, as well as the application of treatments to novel targets, such as the coagulation cascade.
