Endocarditis por Trichoderma longibrachiatum en paciente con nutrición parenteral domiciliaria.

Home parenteral nutrition (HPN) improves the quality of life of the patients although it has complications. Catheter-related infections and mechanical complications are the most frequent ones. We report the case of endocarditis over catheter in a man suffering from short bowel and receiving HPN. The special features of the case are firstly the catheter was a remaining fragment on the right atrial and secondly the infection was caused by Trichoderma longibrachiatum, an isolated fact regarding this pathology so far. Conventional surgery was applied to take the catheter out. Staphylococcus epidermidis, Ochrobactrum anthropi and Trichoderma longibrachiatum were isolated from the surgical specimen. The extraction of the infected catheter along with antibiotic therapy led to the complete recovery of the subject. Ochrobactrum anthropi and Trichoderma longibrachiatum are unusual microorganisms but they are acquiring more relevance. Although there is no agreement about intravascular retained catheter management, the most recommended approach consists on monitoring them and removing the device in case of complications.

The STOP the Bleeding Campaign.

According to the World Health Organization, traumatic injuries worldwide are responsible for over 5 million deaths annually. Post-traumatic bleeding caused by traumatic injury-associated coagulopathy is the leading cause of potentially preventable death among trauma patients. Despite these facts, awareness of this problem is insufficient and treatment options are often unclear. The STOP the Bleeding Campaign therefore aims to increase awareness of the phenomenon of post-traumatic coagulopathy and its appropriate management by publishing European guidelines for the management of the bleeding trauma patient, by promoting and monitoring the implementation of these guidelines and by preparing promotional and educational material, organising activities and developing health quality management tools. The campaign aims to reduce the number of patients who die within 24 hours after arrival in the hospital due to exsanguination by a minimum of 20% within the next 5 years.

Bone turnover markers in HIV-infected patients before starting antiretroviral therapy.

Purpose: Bone turnover markers (BTM) - aminoterminal propeptide of type 1 collagen (P1NP) and C-terminal telopeptide of type 1 collagen (b-CTX) - are related to bone density and fracture risk. A high prevalence of osteopenia/osteoporosis and hypovitaminosis D has been reported in HIV patients, however there are few data about BTM in this population. Our aim was to analyse the prevalence of elevated serum levels of BTM in HIV patients before starting antiretroviral therapy (ART), and related factors. Methods: Cross-sectional study of a series of HIV-patients who started ART during June/11-June/12 in our hospital. Patients with presence of diseases or treatments known to affect bone metabolism were excluded. Epidemiological, clinical, and immunovirological data in addition to serum fasting levels of glucose, lipid profile, calcium, phosphate, alkaline phosphatase, 25-hydroxyvitamin D3 (25OHD), parathyroid hormone (PTH), P1NP, and β-CTX were collected. Definitions: hypovitaminosis D if 25OHD<30 ng/ml, vitamin D deficiency if 25OHD<20 ng/ml; elevated levels of BTM if β-CTX (ng/ml) >0.64 (men<70 years),>0.85 (men>70 years),>0.58 (pre-menopause women), >0.99 (post-menopause women), or P1NP (ng/mL)>69.4 (men<60 years), >71.1 (men>60 years), >55.7 (pre-menopause women), >61.2 (post-menopause women). Results: 47 patients were included, 91.5% men, median age 37.1 years (30.0-44.3), and 93.6% sexual transmission of HIV (34 HMX, 10 HTX). Median time since the diagnosis of HIV was 3.4 months (1.4- 31.7); there were 7 (14.9%) Aids cases, median CD4 count was 277/ mm3 (155-433), and HIV-VL 4.8 log10 (4.1-5.2). Median serum 25OHD was 29 mg/L (21.9-41.1), with a prevalence of hypovitaminosis of 52.2%, and deficiency of 17.4%. PTH was in range in all cases. Median serum P1NP was 33.3 ng/mL (24.5-52.5) and β-CTX 0.25 ng/mL (0.20-0.45); five (11.4%) patients presented high levels of BTM: 4 men, median age 37.1 years, median CD4 count 247/mm3, median HIV-VL 5.18 log10, and one with hypovitaminosis D. Elevated BTM were related with no clinical, analytical, immunovirological parameters nor with serum levels of 25OHD nor PTH. Conclusions: The prevalence of elevated BTM was high in this series of HIV-patients, mostly young men, with short time of HIV infection and with no immunovirologic control. BTM were related with no clinical nor analytical data.
