Microbiologically proven bacterial infections in AIDS.

We have reviewed the incidence, type and site of microbiologically proven bacterial infection occurring in 52 patients with the acquired immunodeficiency syndrome (AIDS) who presented to Southmead Hospital, Bristol between 1990 and 1994. A total of 30 (58%) patients had significant bacterial isolates. The majority of infections were community acquired. Overall, more infections were caused by Gram-negative organisms but Gram-positive organisms predominated in bacteraemia. Mycobacterium avium intracellulare (MAI) caused infection in the largest number of patients, followed by Staphylococcus aureus, Streptococcus pneumoniae, Pseudomonas sp, and Campylobacter sp. When individual episodes of infection were considered, after MAI, Haemophilus influenzae, Streptococcus pneumoniae and Pseudomonas sp were the organisms most frequently isolated; often these same organisms caused recurrent chest infection. Bacterial infections in AIDS patients are common and although they generally respond well to antimicrobial chemotherapy there is a high recurrence rate, particularly in the respiratory tract, which is the commonest site of infection.

Oral tripotassium-dicitratobismuthate in gastric and duodenal ulceration. A double-blind controlled trial.

One hundred ambulant outpatients with active, endoscopically proven peptic ulceration entered a double-blind trial of either tripotassium-dicitratobismuthate or placebo. Thirty-four patients had gastric ulceration, 56 had duodenal ulceration, three had both gastric and duodenal ulcers, and two had stomal ulceration. Five patients with gastric ulceration were withdrawn from the trial. Three patients with both gastric and duodenal ulceration and two patients with stomal ulceration were excluded from statistical analysis. After 28 days of tripotassium-dicitratobismuthate 94% of gastric ulcer patients had significant endoscopic healing (P less than 0.01). Although 75% of duodenal ulcers healed after 28 days of tripotassium-dicitratobismuthate, this was not statistically significant because of a 60% rate of healing with placebo. Tripotassium-dicitratobismuthate produced a significantly quicker symptomatic response in duodenal ulcer patients (P less than 0.01). No serious side effects were recorded, and patient acceptability was high. It is concluded that tripotassium-dicitratobismuthate is an effective agent for promoting gastric ulcer healing and for symptomatic relief in duodenal ulceration.

Zinc absorption in celiac disease and dermatitis herpetiformis: a test of small intestinal function.

The increments in plasma zinc concentrations after an oral dose of elemental zinc (50 mg) as the sulphate were used to assess the intestinal absorption of the metal in 11 patients with dermatitis herpetiformis (DH) before starting a gluten-free diet, 12 patients with newly diagnosed celiac disease (CD), 10 patients known to have CD, and 15 healthy volunteers. The areas under the plasma zinc increment curve plotted against time were determined for 3 (AUC3) and 6 (AUC6) h. The AUC3 in healthy volunteers was 401 +/- 48 mumol 1(-1) 3 h (mean +/- SD); it was reduced in newly diagnosed CD 187 +/- 76 mumol 1(-1) 3 h (p less than 0.001), and in dermatitis herpetiformis 206 +/- 87 mumol 1(-1) 3 h (p less than 0.01); but it was normal in the known CD 396 +/- 204 mumol 1(-1) 3 h, the wide variation reflecting the variable compliance with a previously instituted gluten-free diet. The AUC6 was similarly affected, healthy volunteers 700 +/- 111 mumol 1(-1) 6 h, new CD 380 +/- 169 mumol 1(-1) 6 h (p less than 0.01); dermatitis herpetiformis 471 +/- 107 mumol 1(-1) 6 h (p less than 0.01); known CD 725 +/- 380 mumol 1(-1) 6 h. The AUC3 was more consistently abnormal than conventional tests of small intestinal function. In a prospective study the AUC3 and AUC6 improved and reflected compliance with a gluten-free diet.

An open study of ceftazidime in the treatment of serious bacterial infection.

Ceftazidime, a new parenteral cephalosporin, was given by intravenous bolus injection to 50 patients admitted to hospital with a variety of serious infections. These included septicaemia, bronchopulmonary, urinary, gastro-intestinal and soft tissue infections. The drug proved to be effective against a wide range of organisms, notably opportunistic Pseudomonas aeruginosa infections. In the 32 patients with positive cultures there was a cure rate of 85%. All Ps. aeruginosa infections were eradicated, but two relapsed post treatment in patients with recurrent urinary infections related to indwelling catheters. The drug was well tolerated and no serious side effects occurred. Two patients with salmonella septicaemia relapsed after an initial clinical response, and one of these died.

Acute osteomyelitis in a district general hospital.

A survey of the 58 patients with acute osteomyelitis seen in one general hospital between 1969 and 1979 has shown that, although the condition is less common now than in the pre-antibiotic era, it remains a serious disease. Bone pain and tenderness are still the commonest symptoms, but the source of the infection is less apparent now than it used to be, and this may lead to delay in diagnosis. The antecedent trauma experienced by nearly half the patients probably predisposes to infection by causing local bone damage and thus a focus for secondary infection. The pattern of infecting organisms has not changed much over the past 11 years, but Haemophilus influenzae must be considered in children aged under 5 years. Treatment was the use of antibiotics, with surgical drainage if necessary. The commonest antibiotic used was clindamycin, and chronic osteomyelitis did not develop in patients treated with this antibiotic, whereas all 9 patients who had chronic sequelae necessitating sequestrectomy had received cloxacillin either alone or in combination with another antibiotic.

Fatal Salmonella septicaemia with disseminated intravascular coagulation and renal failure.

Four elderly patients with salmonella septicaemia complicated by irreversible endotoxic shock and acute renal failure are described. The organism isolated from three of the patients with Salmonella typhimurium, which is not usually invasive; the fourth patient was infected with S. abony. The factors associated with the severe systemic infections are discussed. Clinical and haematological findings suggested disseminated intravascular coagulation, and this was subsequently confirmed histologically in each patient by the identification of haematoxylinophil bodies in the pulmonary and renal microcirculations.
