58 granulocytopenic patients with confirmed bronchopneumonia were divided retrospectively into two groups for this pilot study: group 1 included neutropenic patients with venous catheters who were treated with ciprofloxacin (CIP; 200-300 mg, i.v. b.i.d.) + vancomycin (VAN; 0.5-1 g, i.v. b.i.d.), and group 2, which included patients without venous catheters treated with ceftazidime (2 g, i.v. t.i.d.) + gentamicin (1 mg/kg, i.v. t.i.d.). Pneumonia was diagnosed clinically and radiologically in all patients; 92.3% in group 1 and 46.8% in group 2 were also microbially confirmed. Mixed infections were present in most patients. 3 of 26 patients (11.5%) in group 1 and 9 of 32 (20.1%) in group 2 did not recover while 88.5% in group 1 and 71.9% in group 2 recovered. CIP + VAN seems to be more effective in treating pneumonia in neutropenic patients, with only 1 patient in the group suffering an adverse effect compared with 5 in group 2.

In 1987, an outbreak of pneumonia and meningitis caused by an unknown bacterium occurred in a spa therapy centre. Nine isolates of this pathogen constituted a tight DNA hybridization group. rRNA-DNA hybridization and 16S rRNA sequencing showed that the studied bacteria represented a new branch in superfamily II (= gamma subclass) of the Proteobacteria, close to the genus Oceanospirillum. The new bacterium was highly polymorphic and, in young cultures, had curved Gram-negative cells, motile by polar single flagella. The new bacterium differed from the genus Oceanospirillum by its lacking the NaCl requirement and by reducing nitrate into nitrite, producing indole from tryptophan and producing acid from carbohydrates. The name Balneatrix alpica gen. nov., sp. nov. is proposed for the studied organism. The type strain is strain 4-87 (= CIP 103589).

A nonphotochromogenic, rapidly growing Mycobacterium strain was isolated in pure culture from the sputum and the bronchoalveolar fluid of a patient with hemoptoic pneumonia by using axenic media and an amoebal coculture system. Both isolates grew in less than 7 days at 24 to 37 degrees C with an optimal growth temperature of 30 degrees C. The isolates exhibited biochemical and antimicrobial susceptibility profiles overlapping those of Mycobacterium abscessus, Mycobacterium chelonae, and Mycobacterium immunogenum, indicating that they belonged to M. chelonae-M. abscessus group. They differed from M. abscessus in beta-galactosidase, beta-N-acetyl-beta-glucosaminidase, and beta-glucuronidase activities and by the lack of nitrate reductase and indole production activities, as well as in their in vitro susceptibilities to minocycline and doxycycline. These isolates and M. abscessus differed from M. chelonae and M. immunogenum by exhibiting gelatinase and tryptophane desaminase activities. Their 16S rRNA genes had complete sequence identity with that of M. abscessus and >99.6% similarity with those of M. chelonae and M. immunogenum. Further molecular investigations showed that partial hsp65 and sodA gene sequences differed from that of M. abscessus by five and three positions over 441 bp, respectively. Partial rpoB and recA gene sequence analyses showed 96 and 98% similarities with M. abscessus, respectively. Similarly, 16S-23S rRNA internal transcribed spacer sequence of the isolates differed from that of M. abscessus by a A-->G substitution at position 60 and a C insertion at position 102. Phenotypic and genotypic features of these two isolates indicated that they were representative of a new mycobacterial species within the M. chelonae-M. abscessus group. Phylogenetic analysis suggested that these isolates were perhaps recently derived from M. abscessus. We propose the name of "Mycobacterium massiliense" for this new species. The type strain has been deposited in the Collection Institut Pasteur as CIP 108297(T) and in Culture Collection of the University of Goteborg, Goteborg, Sweden, as CCUG 48898(T).

A rapidly growing mycobacterium was isolated in pure culture from the sputum of a 78-year-old woman suffering from hemoptoic pneumonia. The isolate exhibited an antimicrobial susceptibility pattern and a biochemical profile similar to that of Mycobacterium septicum ATCC 700731(T) and shared 100% 16S rRNA gene sequence similarity with this type strain over 1480 bp. Its partial rpoB sequence shared 98.2% similarity with the latter species, suggesting the isolate was representative of a sequevar of M. septicum. Contrary to the type strain, this isolate was resistant to azithromycin, erythromycin, vancomycin and tobramycin. This case illustrates the first isolation from sputum of M. septicum, a member of the Mycobacterium fortuitum group previously isolated once from bacteremia. Strain D13 has been deposited in the Collection de l'Institut Pasteur as CIP 108512.

Secondary sclerosing cholangitis in critically ill patients (SSC-CIP) is a destructive cholangiopathy with a poor prognosis. Liver transplantation (LT) is an established therapeutic option in end-stage liver disease but is insufficiently evaluated in patients with SSC-CIP. Our aim was the retrospective analysis of the outcome and complications of patients with SSC-CIP undergoing LT between 2002 and 2012. Demographic characteristics, laboratory, transplantation, and follow-up data were compared to sex- and age-matched patients undergoing LT because of other reasons. Quality of life (QoL) before and after LT was assessed in a retrospective telephone interview. LT was performed in 21 patients with SSC-CIP. The main causes for intensive care unit admission comprised cardiothoracic surgery interventions (10/21, 48%), polytrauma (6/21, 29%), and pneumonia (3/21, 14%). Median follow-up period after LT was 82 months (interquartile range [IQR], 37-129) for patients with SSC-CIP and 83 months (IQR, 55-104) for control patients. Biopsy-proven rejection episodes in patients with SSC-CIP (4/21, 19%) were similar compared to control patients (12/60, 20%; P = 0.93). Cytomegalovirus infections were equal in both groups (10/21, 48% versus 25/60, 42%; P = 0.64). The 1-, 3-, and 5-year survival rates of patients with SSC-CIP versus control patients were 100% versus 98%, 86% versus 92%, and 76% versus 87%, respectively (P > 0.05). The QoL improved significantly after LT in SSC-CIP. In conclusion, LT is a valid option for patients with SSC-CIP with excellent long-term outcome and improvement of QoL.

Secondary sclerosing cholangitis (SSC) is a term used for a group of chronic cholestatic disease affecting the intra- and/or extrahepatic biliary tree with inflammation and progressive stricture formation, which can lead to biliary cirrhosis. A newly recognized form of SSC is secondary sclerosing cholangitis in critically ill patients (SSC-CIP). Pathogenesis is believed to involve ischemic injury of intrahepatic bile ducts associated with prolonged hypotension, vasopressors administration, and/or mechanical ventilation in patients treated in the intensive care unit (ICU). Patients diagnosed with SSC-CIP have no prior history of liver disease and no known pathologic process or injury responsible for bile duct obstruction prior to ICU treatment. Reasons leading to ICU treatment are many including multitrauma, burn injury, cardiac surgery, severe pneumonia, other infections, or bleeding after abdominal surgery. Patients have in common prolonged ICU admission. SSC-CIP is associated with rapid progression to liver cirrhosis and poor survival with limited treatment options except a liver transplantation. Transplant-free survival is around 17-40 months, which is lower than in other SSC patients. During the initial stages of the disease, the clinical symptoms and biochemical profile are not specific and easily missed. Biliary casts formation may be considered pathognomonic for SSC-CIP since most patients have them in early stages of the disease. Increased awareness and early detection of the disease and its complications is considered to be crucial to improve the poor prognosis.
