Streptococci of Lancefield Group B (GBS) are known to cause maternal
sepsis
and neonatal infection, whereas streptococci Lancefield Group A (GAS) cause vulvo-vaginitis in both children and adults. Prevalence of SGB colonization of the lower genital tract of normal women is between 4-18%, with higher rates found in hospital personnel and delivery rooms. Such high carriage rates may be a significant factor in nosocomial transmission of GBS to neonates. Symptomatic infection is uncommon and usually secondary to other pathological states. Amnionitis is a complication of vaginal carriage of GBS and there is now evidence that chorioamnionitis is associated with pre-term labour and its attendant problems. GBS infection of the male genitalia has also been described. Intrapartum chemoprophylaxis has been shown to prevent early onset GBS disease of the neonate. Prevalence of GAS in the genital tract is lower than that for GBS, but is more likely to be symptomatic. The response to penicillin is usually prompt. Optimal drug regimens need to be determined, particularly for use in pregnancy.

Cytomegalovirus retinitis is a major cause of morbidity in patients with AIDS. The conventional treatment approach has involved insertion of a central venous catheter and intravenous administration of ganciclovir and/or foscarnet. This has been associated with systemic toxicity, line-related
sepsis
, and implications for patient quality-of-life. An oral formulation of ganciclovir has now been licensed for use as maintenance therapy in CMV retinitis. Multicentred trials comparing oral and intravenous ganciclovir have suggested that although the efficacy may be marginally reduced with the oral formulation, the associated toxicity is significantly lower. With careful and informed decision-making by both clinician and patient, the opportunity exists to enhance the quality of life in this patient group.

In order to describe the clinical features of HIV (non-AIDS), particularly injection drug use (IDU) related HIV, in patients attending the Regional Infectious Diseases Unit in Edinburgh, a prospective review utilizing the WHO staging system of the 680 HIV positive patients, 30% of whom were women and 68% were infected via IDU, was undertaken. Despite the fact that the majority of drug users and heterosexuals enrolled asymptomatic, by 1993, 71% of the patients had developed some HIV related clinical problem. The important clinical problems observed for the cohort were; minor skin problems, minor bacterial infections, major bacterial
sepsis
, oral thrush, oral hairy leucoplakia, significant weight loss of > 10%, HIV related thrombocytopenia and of course AIDS. Unlike previous reports from other areas, in Edinburgh drug users were not more likely than other risk groups to develop severe bacterial disease. Differences in morbidity and mortality rates by risk group but not by gender were noted but these may well be affected by the very different enrolment pattern observed in the various risk groups. The pre-AIDS mortality rates for drug users were remarkably similar to published rates from other centres.

Leucopenia and neutropenia in HIV appears to be much less common than in the context of haematological malignancies although severe neutropenia (< 0.75 x 10(9)/l) occurs in as many as 70% of patients with AIDS often related to concomitant drug therapy. In addition to low numbers of neutrophils there is also some evidence of defective neutrophil function in HIV/AIDS (chemotaxis, bacterial killing, phagocytosis and superoxide production). However the frequency and importance of these defects is as yet not known because simple and reproducible tests of neutrophil function are not yet available to the majority of clinicians. Despite the relative scarcity of severe neutropenia in early HIV, bacterial
sepsis
is a major clinical problem which usually manifests itself as either pneumonia, bacteraemia or both at a frequency of between 8-20 per 100 person years depending upon location, risk activity etc. Amongst drug users, the inhalation of recreational drugs particularly after Pneumocystis carinii pneumonia (PCP) has been shown to be a major risk factor for pneumonia. The incidence of bacterial
sepsis
in patients with AIDS is more difficult to determine since it is often overshadowed by other more dramatic opportunistic infections. However, throughout the course of AIDS, bacterial infections are a common problem particularly in the presence of one or both of concomitant drug therapy and indwelling intravenous lines utilized in late stage disease. Consequently, since bacterial infections are common and cause considerable morbidity and mortality they should be considered in the differential diagnosis of most presentations.

Central venous catheters (CVCs) for patients with AIDS are at risk of a number of complications including bacterial infections. A 6-year retrospective review was undertaken of the records of the 33 patients (42% infected by injection drug use (IDU)) who received intravenous therapy both in hospital and at home via CVCs. Twenty-eight per cent of 53 insertions suffered a complication, the commonest of which was a pneumothorax (8%). The post insertion complication rate was 0.98/100 catheter days (cd). Thrombotic occlusion (0.15/100 cd) was the commonest non septic event while
sepsis
was overall the commonest event (0.69/ 100 cd) of which half were considered serious (0.33/100 cd). The most frequently isolated organisms were Staphylococci spp. (71%). The median time to an exit site infection was 59 days and to serious catheter
sepsis
86 days. Infection did not differ significantly with age, gender, transmission risk activity or catheter type although Portacaths had the lowest rate of infection (0.33/100 cd). The median survival of the 53 CVCs was 88 days although if the temporary catheters were excluded it was 118 days. Kaplan-Meier estimates of survival analysis revealed 55%, 32% and 19% of all the CVCs surviving 3, 6 and 12 months respectively. Our experience suggests that home intravenous therapy and previous IDU does not preclude the use of CVCs although further research is needed on reducing the infection-related complications of such therapy.

Fifty-four episodes of Xanthomonas maltophilia infection were observed in 52 HIV-infected patients out of 2062 assessed (2.52%) over a 6-year period:
sepsis
/bacteraemia in 44 cases, lower airways infection in 5 cases, urinary tract infection and pharyngitis in 2 cases each, and lymph node involvement in one patient. X. maltophilia represented the fourth most common non-mycobacterial bacterial pathogen responsible for bacteraemia in HIV-infected patients: 44 cases out of 721 diagnosed (6.1%). When compared with non-typhoid Salmonella spp. bacteraemia, an increased risk to develop X. maltophilia disseminated infection was seen according to the progression of HIV-related immunodeficiency, the occurrence of leukopenia-neutropenia, central venous catheterization, previous antibiotic and/or corticosteroid treatment, and hospitalization. In 3 patients suffering from concurrent AIDS-related disorders, X. maltophilia infection contributed to death, while a recurrence occurred in 2 cases only. Due to the poor antimicrobial susceptibility of this pathogen (also confirmed in our series), X. maltophilia bacteraemia associated with advanced HIV infection and concurrent risk factors, may represent a potentially severe disease.

Our objective was to describe clinical features and predisposing factors attributed to lactic acidosis in 4 HIV-infected patients on long-term nucleoside reverse transcriptase inhibitor (NRTI) therapy. All patients had received at least 6-20 months of NRTI-containing antiretroviral therapy: all used stavudine (d4T), in one combined with lamivudine (3TC), in the other 3 with didanosine (ddI); in one hydroxyurea was added. In all, the initial symptoms were gastrointestinal (nausea and vomiting), followed by tachypnoea preceding the lactic acidosis; death followed 6-22 days after admission (liver failure and uncontrollable arrhythmias). Treatment with riboflavin was unsuccessful in one patient. The only definite risk factor in all cases was NRTI-induced mitochondrial toxicity; one patient was concomitantly treated for Kaposi's sarcoma (with bleomycin and vinblastine) and one just recovered from pneumococcal
sepsis
. None of the patients had a history of chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infection. In all patients, some sort of toxicity to other previously used NRTIs had occurred earlier. Lactic acidosis occurred after months of NRTI therapy in patients who had already suffered other forms of NRTI toxicity. Concomitant diseases or comedication might have aggravated the mitochondrial toxicity of the NRTIs. Screening methods to detect mitochondrial toxicity are necessary, since lactic acidosis occurs rather unexpectedly, with a rapid, fatal course.

Severe lactic acidosis has been increasingly reported as a potentially fatal complication of HIV treatment. We report on an asymptomatic HIV-infected woman treated with stavudine, lamivudine and indinavir for one year. She was hospitalized because of progressive dispnoea, oedema, cyanosis and severe lactic acidosis. Arterial blood pH was 6.98, bicarbonate 4.4 mmol/l (normal value 22-26), blood lactate: 29.7 mmol/l (normal value <2.2). Hepatic function was normal. She had an impressively rapid response (within a few hours) to empirical treatment with thiamine (100 mg i.v.). No evidence of
sepsis
or malabsorption were identified and vitamin B1 level was not tested before thiamine infusion. Three months later she was re-started successfully on nelfinavir plus nevirapine. The rapid response to thiamine infusion deserves a careful attention and such an approach should be considered in similar cases as a support treatment of this potentially life-threatening complication of HIV therapy.

A profoundly immunosuppressed HIV-infected man developed
sepsis
syndrome with multi-organ failure. A septic screen failed to identify a bacterial or fungal cause and despite empirical treatment for these pathogens the patient remained unwell. Investigations revealed disseminated tuberculosis. With specific anti-tuberculosis therapy the patient rapidly recovered. Although most cases of
sepsis
syndrome in HIV-infected patients are due to bacteria, tuberculosis should be added to the differential diagnosis of this presentation.
