Four weeks after a slight scratch a 43-year-old man noted a severe back pain. Physical examination gave suspicion of a bacterial spondylitis. From the biopsy of the involved vertebral body Haemophilus aphrophilus was isolated under aerobic growth conditions.

Vertebral biopsies were performed in 28 patients, 17 males and 11 females, because of vertebral body and disc changes between June 1978 and May 1982. In two patients biopsy was performed in two segments. Punctures were done in local and superficial anaesthesia of the vertebral body periosteum during continuous fluoroscopy control using Jamshidi's instrumentation. Aspiration and tissue cylinders were evaluated histologically and bacteriologically. There were no complications among the 8 thoracic and 22 lumbar biopsies. A histologic diagnosis could be established in 22 cases (78.6%): plasmocytoma (n = 2), spontaneous deformation of the spine in osteoporosis (n = 3), Scheuermann's disease (n = 1), specific (n = 2) and nonspecific (n = 14) spondylitis. Demonstration of bacteria was possible in 5 out of the 16 cases of spondylitis (31.25%): in two cases tubercle bacilli were demonstrated and once each salmonella group B, Haemophilus aphrophilus and coagulase-negative staphylococci. Only in 6 cases a diagnosis could not be established from the biopsy material.

We report a case of lumbar spondylitis due to Haemophilus aphrophilus in a 36-year-old man with monoclonal gammopathy of undetermined significance. Haemophilus aphrophilus is a gram-negative capnophilic, slow growing coccobacillus, a component of the normal human flora of the oropharynx. This organism is considered an uncommon human pathogen and has been reported in the literature in only 10 cases of bacterial spondylitis. We review the bacteriological and clinical findings, predisposing conditions and the previously reported infections caused by Haemophilus aphrophilus. The patient responded well to antibiotic treatment with ciprofloxacin.

The antibody response to bacteria of the so-called HACEK group, i.e. Haemophilus spp., Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens and Kingella kingae, was measured in sera of six patients with endocarditis. The corresponding isolates from their blood cultures were identified by conventional methods, including reactions for nitrate reduction and catalase as well as acid production from sugars. Crude antigens were prepared by glycine extraction and sonification of the blood culture isolates, and used to determine titers by complement fixation. A patient with Haemophilus parainfluenzae bacteremia received a short course of antibiotic therapy, and relapsed with spondylitis and endocarditis 5 months later. Titers of sera against his own isolate rose from 1:40 to 1:320 and fell to 1:40 after therapy within one year. A patient with C. hominis endocarditis had a similarly prolonged course. The complement fixation titer against his own isolate was already 1:240 before antibiotics were administered. Another patient with C. hominis endocarditis presented a titer of 1:320 2 weeks after the diagnosis. These three patients revealed C-reactive protein values over 50 mg/l in the first serum sample. Decrease of both antibody titers and C-reactive protein values correlated with clinical improvement. Two patients with prosthetic valve replacement 5 months earlier developed C. hominis and K. kingae endocarditis, respectively. At admission, C-reactive protein values were 64 and 82, respectively, and therapy was instituted immediately. The first sera were received 3 and 6 weeks, respectively, after isolation of the corresponding blood culture isolates and revealed already low titers, i. e. 1:80 and 1:60, respectively. A woman with A. actinomycetemcomitans endocarditis received immediate therapy and did not develop titers against her own isolate. CRP was 100 at admission and remained over 50 5 weeks later. We conclude that the complement fixation assay with individual antigen preparations was easy to perform and allowed monitoring of the antibody response in 5 of 6 HACEK endocarditis cases under therapy, but the usefulness of this method to find culture-negative HACEK endocarditis needs to be established.

Infectious complications of sickle cell disease are common and can be serious and difficult to diagnose. Epidemiological aspects of these infections are well documented. The most common germ in children is pneumococcus followed by Haemophilus influenzae and minor salmonella. In adults gram-negative germs including minor salmonella are the most frequent. The purpose of this report is to describe a case of a Citrobacter freundii spondylitis with prevertebral abscess extending to dorsal and lumbar spinal areas. Diagnosis was made during work-up for persistent vaso-occlusive manifestations. Treatment consisted of percutaneous lumbar drainage associated with antibiotherapy.
