A prospective study of neutropenia induced by high doses of beta-lactam antibiotics.

A prospective study on the effect of beta-lactam antibiotics on granulopoiesis was carried out in 29 consecutive patients with bacterial endocarditis. Fourteen patients received a high dose of benzylpenicillin, up to 18 g/day, but in only three of them could the treatment be fulfilled as planned, for a mean time of 25 days. In 11 benzylpenicillin treated patients treatment had to be discontinued because of fever, rash or neutropenia. Neutropenia appeared in seven patients after 14-24 (mean 22) days. No superinfection occurred during the neutropenic phase which lasted 2-12 days. Patients with neutropenia differed significantly from others in having a lowered pretreatment neutrophil count (3.2 vs 10.4). In 15 patients treated with other beta-lactams, three cases of fever and rash and one case of neutropenia were seen in patients treated with cloxacillin 12 g daily. It was concluded that a daily dose of 18 g of benzylpenicillin is too high for longer treatment periods and that patients with initial low counts of neutrophils have an increased risk of developing neutropenia.

Ceftazidime and renal function.

Glomerular filtration rate (GFR) as measured by 51Chrome-EDTA clearance, decreased with a mean of 10 ml/min during therapy with ceftazidime 2 g bid in 16 patients with initial GFR of 30 to 110 ml/min. A significant increase in the excretion of urinary alanine aminopeptidase was also found. In another three patients with initial GFR of 17-22 ml/min increases in serum creatinine during therapy were noted. These observations indicate that ceftazidime should be used with caution in patients with impaired renal function and not be combined with nephrotoxic drugs until the safety of such combinations has been studied.

Adverse reactions to intravenous administration of fusidic acid.

To study adverse reactions associated with intravenous administration of fusidic acid 6 patients were treated with fusidic acid intravenously in association with a major large bowl operation, and 9 patients were treated in the same way because of staphylococcal infections. The main adverse reaction was thrombophlebitis, which occurred in as many as 12 of 14 patients who were treated for 2 days or longer. Three surgical patients developed postoperative hyperbilirubinaemia, but studies of liver function before and during treatment in 6 of the patients with staphylococcal disease revealed no adverse liver reactions. Intravenous administration of fusidic acid into a peripheral vein for 24 h or more involves an extremely high risk of developing thrombophlebitis.

An outbreak of trichinosis in Lebanon.

In 1982 an outbreak of trichinosis occurred in an area of south Lebanon consisting of 4 villages, including 6440 persons. In 267 households, involving 2456 persons, typical clinical signs of Trichinella spiralis infection could be recognized among household members. Twenty-one of these households, including 193 persons, were randomly chosen for further studies. Nearly half of the household members (46%) had clinical symptoms consistent with acute trichinosis. 12 of 16 tested persons had high anti-Trichinella antibody titres (12 positive by indirect immunofluorescence (IIF) and 11 by enzyme-linked immunosorbent assay). Class-specific antibodies, IIF-immunoglobulin (Ig) G, IgM and IgA, were detected in most tested cases. Of the remaining 4 seronegative cases, 3 had a duration of clinical symptoms < or = 12 d. High peripheral eosinophilic counts (> 20%) were noted in 8 of 16 cases. In total, 15 of 16 cases were positive by one or more of these tests. The outbreak constituted one of the most extensive single outbreaks reported with a calculated > 1000 clinical cases. The cause was attributed to consumption of raw pork meat, an ingredient of kebbeh nayyeh, a favourite Lebanese dish.
