An etiologic study was made of 107 cases of granulomatous hepatitis which were observed in a Department of Internal Medicine between January, 1971 and December, 1977 (excluding the hepatobiliary diseases). The most common etiology was tuberculosis (30 cases, 28 percent) followed by sarcoidosis (19 cases, 17.7 percent), Mediterranean exanthematous fever (13 cases, 12.1 percent), brucellosis (8 cases, 7.4 percent) typhoid fever (7 cases, 6.5 percent) and the idiopathic forms (8 cases, 7.4 percent). A lower rate of incidence was among Hodgkin's disease, toxoplasmosis, adenocarcinomas, leprosy, and those of unknown etiology, classified in this way because the study and follow-up of the patients could not be completed. There were, moreover, individual cases caused by mononucleosis, BCG reaction, hypogammaglobulinemia, celiac disease, and temporal arteritis. From a clinical point of view 50 percent of the patients had hepatomegaly and moderate disturbance of the liver enzymes. The most important enzymatic increases were detected in the cases caused by brucellosis; in the cases which were secondary to sarcoidosis the liver enzymes were normal. A comparison is established between the etiologic incidence of the present series and of others published in the literature. The causes and diagnostic problems of this type of lesion are discussed.

A retrospective postal survey of 21 000 medical laboratory workers in England and Wales showed 18 new cases of pulmonary tuberculosis in 1971, a five-times increased risk of acquiring the disease compared with the general population. Technicians were at greatest risk, especially if they worked in morbid anatomy departments. Of the 35 cases of hepatitis, the technicians were again the occupational group most likely to acquire the disease. Microbiology staff were twice as likely to report shigellosis as those in other pathology divisions but only one case of brucellosis was reported in the whole laboratory population. A similar survey carried out in 1973 of 3000 Scottish medical laboratory workers corroborates the results from England and Wales. Medical laboratory workers continue to experience a considerable risk of developing an occupationally acquired infection. Improvements in staff safety and health care seem to be necessary.

IgG and IgM anti-cardiolipin antibodies were measured, by an ELISA technique, in the sera of patients with B hepatitis (28), infectious mononucleosis (10), chicken pox (12), HIV infection (20), acquired toxoplasmosis (41) and other infectious diseases [HBsAg+ chronic hepatitis (5), brucellosis (6), herpes zoster (4), boutonneuse fever (3), viral pneumonitis (4), rheumatic fever (2)]. Increased levels of anti-cardiolipin antibodies (aCL), at least in one immunoglobulin class, were detected in 37 out of 135 patients [27.4%; range: 7.3% (in the patients with toxoplasmosis) -80% (in the patients with HIV infection)]. Low or medium titer aCL were present in 28 patients, high titer in 9 (6 with HIV infection, 2 with chicken pox and I with lymphoadenopathic toxoplasmosis). None of the manifestations associated with aCL was present in the aCL-positive patients. Finally, positivity for aCL didn't seem to modify the clinical picture and the prognosis of the infectious disease.

From May to September 1988, eight employees of a microbiology laboratory developed acute brucellosis (attack rate, 31%). Seven of the eight affected employees had clinical illness ranging from a nonspecific, flulike illness to severe hepatitis. Blood cultures obtained from five of the affected employees (63%) were positive for Brucella melitensis, biotype 3. Comparison of cases and controls showed that there were no risk factors besides employment in the laboratory. Based on work locations, assignments, and interviews, it was found that person-to-person, droplet, food-borne, and waterborne spread were unlikely. Our investigation disclosed that 6 weeks before the outbreak began, a frozen brucella isolate from a patient hospitalized 3 years earlier had been thawed and subcultured without the use of a biologic safety cabinet. This clinical isolate was subsequently identified as B. melitensis, biotype 3, identical to the employee isolates. It is presumed that transmission occurred via the airborne route. This outbreak reemphasized that all work on Brucella species, an established biosafety level 3 organism, must be conducted under a biologic safety hood. Furthermore, it might be prudent to perform all clinical "setups" under a safety hood since aerosolization commonly occurs during the initial processing of specimens and the majority of these specimens are from patients with uncertain diagnoses.

Many viruses, bacteria or parasites can survive in stored blood for varying lengths of time. Recipients are therefore exposed to a risk which depends on the prevalence of pathogens in blood donor populations, the clinical and laboratory controls performed in blood transfusion centres and the efficiency of the patient's immune system. Beside the HIV and hepatitis viruses, transfusions may transmit the HTL virus in endemic areas or if the blood donor comes from one of these areas (e.g. the French West Indies), the CMV virus (but only in patients with weak immune defences) and some exotic viruses in specific regions. As regards bacterial agents, syphilis is prevented by blood storage at 4 degrees C for 72 hours and brucellosis remains a minor risk, but the very rare endotoxinic shock is severe and lethal in two-thirds of the cases. Infestation by parasites is common in certain areas, but it may occur in France after transfusion from blood donors coming from these areas; malaria transmitted by blood perfusion is a real problem. Drastic procedures of rejection of blood donors at risk, including examination and laboratory screening, must be applied and are effective in preventing these dangers. These procedures are well-known and are compulsory in France.

The case of a young shepherd with Brucella melitensis aortic valve endocarditis is presented. His illness ran an afebrile course and was also complicated by disseminated intravascular coagulation (DIC), nephritis, hepatitis and peritonitis, all of which responded well to supportive measures and a combination of tetracycline, trimethoprim-sulphamethoxazole and amikacin sulphate. The fact that even the most severe case of brucellosis can present without fever is stressed.

A case of brucellosis associated with peritonitis, intestinal obstruction, granulomatous hepatitis, inappropriate antidiuretic hormone (ADH) secretion and meningitis is reported. Initially, the patient was diagnosed as a case of disseminated tuberculosis and treated accordingly. However, the serologic tests for brucellosis were strongly positive and the patient was subsequently treated as a case of brucellosis and recovered fully. The gastrointestinal manifestations of brucellosis are reviewed.

Circulating immune complexes are thought to play an essential part in the pathogenesis of necrosing angiitis. This theory also allows a role to be attributed to certain infectious agents (viral, bacterial, parasitic) in the development of periarteritis nodosa (PAN). An infectious syndrome was found in all our 9 patients, aged 26 to 69 years, with histologically confirmed PAN: previous infection (over 15 days before hospital admission): otitis, hepatitis B, tonsillitis, ascaris (Case n.7), pulmonary tuberculosis, brucellosis, seropositivity for Chlamydia trachomatis (Case n.9), paratyphoid (Case n.5), seropositivity for Yersiniosis pseudo-tuberculosis (Case n.2), seropositivity for Chlamydia trachomatis (Cases 3 and 4), seropositivity for toxoplasmosis (Cases 4 and 6), seropositivity for rubella (Case n.8). Recent infection (less than 15 days before hospital admission): staphylococcus aureus septicaemia (Case n.1); Group A betahemolytic streptococcal urinary infection (Case n.2); Group A betahemolytic streptococcal otitis media; pseudomonas aeruginosa and Klebsiella septicaemia; enterococcal cystitis (Case n.4); progressive pulmonary tuberculosis (Case n.6), acinetobacter pneumonia (Case n.9). The HBs antigen was only found in one patient (Case n.6), who had an active hepatitis.

In reviewing 54 cases of granulomatous hepatitis (GH) diagnosed among 2,620 laparoscopies, we have been able to classify the capsular GH changes into five patterns: Macular, exudative, pinpoint, granular and cord-like. The exudative pattern was the most frequent one, and predominated in brucellosis. The granular pattern was most common in tuberculosis. Furthermore, 35 additional cases, in whom a laparoscopic diagnosis of GH was not confirmed by liver biopsy, showed a trend to a final diagnosis consistent with multifocal diseases, whenever laparoscopic pictures were similar to the patterns described herein. We speculate with the limits associated with the use of only a single biopsy sample. We conclude that laparoscopy permits the establishment of a tentative diagnosis of GH, which could provide us with valuable information about the usefulness of obtaining multiple hepatic biopsies.

Serum samples were collected from 116 wolves which were captured in southcentral Alaska during 1975 through 1982. Antibodies to the following infectious disease agents were found: infectious canine hepatitis virus-72 of 87 (81%), canine parvovirus type 2-0 of 55 (0%) through 1979 and 10 of 32 (31%) after 1979, Francisella tularensis-16 of 67 (25%), canine distemper virus-10 of 83 (12%), Coxiella burnetti-5 of 95 (5%), rabies virus-1 of 88 (1%), Brucella spp.-1 of 67 (1%), Leptospira interrogans-1 of 82 (1%). Apparently rabies, brucellosis, and leptospirosis were rare and had little effect on the wolf population. Conversely, the other five infections were comparatively common and may have had a negative impact on the health of specific individual wolves, but did not appear to influence the health of the population.
