Pefloxacin 800 to 1200 mg daily was given for 3 to 20 days, orally or intravenously, to 84 immunocompromised patients. Five patients dropped out because of side effects and 2 for other causes. Treatment efficacy was evaluated in 77 patients, 43 men and 34 women, aged 18 to 80 years. Immunodepression resulted from malignancy in 46 patients, LAS/ARC or AIDS in 28, and from unknown causes in 3. Fifty-eight patients had documented infections (respiratory-tract infections 29, urinary-tract infections 13, septicemia 10, other 6) and 19 had a fever of unknown origin (FUO). Cure or significant improvement of symptoms was achieved in 81% of patients with documented infections and in 74% of patients with FUO. Side effects (mainly gastrointestinal disturbances and skin rash) occurred in 7 patients (8.2%), including dropouts. These results suggest that pefloxacin may be useful for the antibacterial treatment of immunodepressed patients.

We analysed 13 pregnancies from HIV-positive women, 12 intravenous drug abusers, and found the following complications: (1) 4 small-for-date babies and 1 premature baby; (2) 12 spontaneous births, 1 cesarean section; (3) 6 children with acute withdrawal syndrome and/or sepsis; (4) 2 children have AIDS, 3 mothers too; 1 child got ARC; (5) 4 children became HIV-negative. We propose some guidelines through pregnancy and birth for this group at risk.

This review describes the transmission, clinical picture and immunological abnormalities of HIV infection in children in general, and the special problems of AIDS in African children. The review begins with a thorough introduction to the epidemiology of AIDS. Transmission to children generally involves vertical transmission by placental transfer or transmission of HIV via transfusion of blood and blood products, or by contaminated needles. Casual transfer is unknown, and only a few cases of transmission via breast milk are known. The clinical picture of HIV infection in infants and children differs from that in adults in 3 important aspects: earlier onset, different clinical presentation and existence of AIDS embryopathy. The average onset was 5 months of age. The most common symptoms in young children are chronic interstitial pneumonitis without demonstrable etiology, hepatomegaly, failure to thrive, adenopathy, diarrhea, oral or perineal thrush, eczema and thrombocytopenia. The common opportunistic infections are pneumocystis carinii pneumonia, cytomegalovirus, Epstein-Barr virus, Cryptosporidium diarrhea, pyogenic infections of the middle ear and gram-negative septicemia. Several infections seen in adult AIDS cases are rare in children: mycobacterium avium-intracellulare, toxoplasma gondii, hepatitis B, as well as Kaposi's sarcoma, malignant lymphoma and cardiac abnormalities. The AIDS embryopathy or HIV dysmorphic syndrome is characterized by immunological abnormalities, growth failure, and craniofacial dysmorphism, particularly microcephaly, prominent box-like forehead, hypertelorism, flattened nasal bridge, obliquity of the eyes, blue sclerae and patulous lips. AIDS in African children is extremely difficult to diagnose because of similarities between the presenting symptoms and those commonly seen in sick children there, many of whom are also immune compromised. Where serotesting is available, the picture is complicated by cross reaction between the test agents and some factor found in sera from malaria patients. Seropositivity in some areas is high, increased by the prevalence of transfusion and injection treatments. Diagnosis is made more difficult by lack of laboratory facilities and difficulties in follow-up for pediatric patients. The CDC definitions of AIDS and ARC, and the WHO/CDC definitions of AIDS are appended.

Twenty-four episodes of bacterial infections were identified over a 18 month period in 11 patients (8 with acquired immunodeficiency syndrome and 3 with AIDS related complex). Eight of the 11 infected patients were drug abusers and 3 homosexual people. Nosocomial bacterial infections were common in patients with AIDS and had high fatality rates. Gram-negative bacteria resulted the most common micro-organisms (E.coli, Proteus, Enterobacter, Serratia, Klebsiella). The Aztreonam treatment was very useful in providing bacteria eradication. Gram-positive bacteria as Staphylococcus from a sepsis and Enterococcus from a cystopyelitis were eradicated by B-lactam antibiotics. Common micro-organism are frequent in patients affected by LAS/ARC or AIDS and they negatively interfere with the disease outcome.

56 cases of pregnant women with a positive HIV serology were reported in 20 months at the Maternity of the Nice Hospital Center. In 10 cases, there were clinical signs of the disease (9 ARC-Syndrome, one case of AIDS). The predisposing factor was most of the time drug addiction, 53 cases (94.5%) and one case occurred after a blood transfusion. In the majority of the cases (52%) the pregnancy was pursued because of the late term or the patient's decision. A therapeutic abortion was performed in 12 instances (25%) and an interruption before 12 weeks of amenorrhea in 15 cases. 24 women delivered. The obstetrical complications were frequent with especially a fetal death in utero, five premature deliveries and fifteen hypotrophies. A severe infectious complication (septicemia, pneumopathy secondary to Pneumocystis carinii) was observed in 9 cases, a marked thrombopenia causing profuse post-partum haemorrhages in one case. Finally, one woman died 35 days after delivery. The study of the consequences on the child is incomplete because of insufficient follow-up: all children were sero-positive at birth and among thirteen children aged between 12 to 20 months, there were one death, one AIDS syndrome, 4 ARC-syndrome, 4 sero-positive and 3 sero-negative. The notion of HIV sero-positivity in a pregnant woman presents serious problems for the obstetrician. Decompensation of the disease during the pregnancy is uncertain but it is now confirmed that the child is affected, and this is a well established fact. These important consequences lead to propose, at this time a therapeutic interruption of pregnancy when possible, depending on the term, and when accepted by the patient.

The occurrence of reported cases of AIDS in children in Uganda, and the most common symptoms are discussed. By May 1988, 359 cases of AIDS in children has been reported. All but 12 were in babies less than 2 years of age, suggesting that maternal transmission, rather than casual contact, had caused the infection. Information was available on HIV status of 224 mothers. 42% of these had AIDS or ARC (AIDS related complex). 85 of 87 mothers whose sera had been tested were positive for HIV. Blood testing is not accurate in children until about 15 months of age, since maternal antibodies persist after birth. The most common symptoms seen in childhood AIDS in Uganda are weight loss, failure to thrive, chronic diarrhea, and repeated, chronic oral thrush (candidiasis). Other indicators are otitis media, generalized dermatitis, tuberculosis, septicemia and meningitis. Less common signs are shingles, Kaposi's sarcoma and Cryptospor meningitis. Some of these clinical findings are common in this area, so it is important to define a working clinical case definition of pediatric AIDS.

This international expanded access programme was initiated to provide zalcitabine (o 75 mg three times daily) to patients with AIDS or advanced ARC who had failed, were no longer able to tolerate or were ineligible to receive zidovudine (ZDV). Data are available from 517 patients. No unexpected adverse events occurred during the study with 13.2% of patients discontinuing treatment due to drug-related adverse events. Peripheral neuropathy (PN) was the most common adverse event reported. This was considered to be at least possibly related to zalcitabine in 12.2% of patients, with only 2.3% of patients withdrawing from the study due to zalcitabine-associated PN. Patients with a baseline diagnosis of AIDS and a CD4 count </= 50 cells/mm(3) were most likely to develop PN on zalcitabine. Fifty-seven patients (11%) died during the study, with death considered to be at least remotely related to therapy in only 2 cases (1 case each of pancreatitis and cerebral toxoplasmosis with possible sepsis/granulocytopenia).

Nociceptin/orphanin FQ, N/OFQ, and its receptor NOP represent a non-opioid branch of the opioid superfamily that were first studied for their effects on pain responses. Both N/OFQ and NOP are involved in a wide range of 'non-pain' responses including immunomodulation and cardiovascular control. There is now growing interest in this system in inflammation and sepsis, which is the focus of this review article. The N/OFQ-NOP system is present in immune cells and N/OFQ modifies immunocyte function. On the basis of various in vitro and in vivo studies, N/OFQ increases the inflammatory response in healthy anaesthetized animals and in those with a septic or inflammatory process. It affects tissue perfusion, increases capillary leakage and inflammatory markers, and leads to immune cell chemotaxis. Moreover, NOP activation produces bradycardia and hypotension. Systemic N/OFQ administration also increased mortality in an animal model of sepsis, and there is limited evidence for increased plasma N/OFQ concentrations in patients with sepsis who died compared with those who survived. There is a need for further observational and mechanistic studies in patients with established inflammatory processes or sepsis. These studies may facilitate the design of appropriate clinical studies to evaluate NOP ligands as modifiers of the inflammatory response.

Nociceptin/orphanin FQ (N/OFQ) is a seventeen-amino acid peptide that is the endogenous ligand of a G-protein-coupled receptor (NOP). Various immune cells express the precursor protein and secrete N/OFQ as well as display binding sites for this peptide. The functional capacity of NOP receptor was demonstrated in vitro and in vivo studies by the ability of N/OFQ to induce chemotaxis of immune cells, to regulate the expression of cytokines and other inflammatory mediators, and to control cellular and humoral immunity. In this context, N/OFQ could modulate the outcome of some inflammatory diseases, such as sepsis and autoimmune pathologies by mechanisms not clearly elucidated yet. In fact, human body fluid revealed increased levels of N/OFQ under sepsis, arthritis, and Parkinson's diagnose. Preclinical studies pointed to the blockade of NOP receptor signaling as successful in treating these experimental conditions. Further preclinical and clinical studies are required to investigate the potential of NOP ligands in treating inflammatory diseases.

Daily patterns of activity and physiology are termed circadian rhythms and are driven primarily by an endogenous biological timekeeping system, with the master clock located in the suprachiasmatic nucleus. Previous studies have indicated reciprocal relationships between the circadian and the immune systems, although to date there have been only limited explorations of the long-term modulation of the circadian system by immune challenge, and it is to this question that we addressed ourselves in the current study. Sepsis was induced by peripheral treatment with lipopolysaccharide (5 mg/kg) and circadian rhythms were monitored following recovery. The basic parameters of circadian rhythmicity (free-running period and rhythm amplitude, entrainment to a light/dark cycle) were unaltered in post-septic animals compared to controls. Animals previously treated with LPS showed accelerated re-entrainment to a 6 hour advance of the light/dark cycle, and showed larger phase advances induced by photic stimulation in the late night phase. Photic induction of the immediate early genes c-FOS, EGR-1 and ARC was not altered, and neither was phase-shifting in response to treatment with the 5-HT-1a/7 agonist 8-OH-DPAT. Circadian expression of the clock gene product PER2 was altered in the suprachiasmatic nucleus of post-septic animals, and PER1 and PER2 expression patterns were altered also in the hippocampus. Examination of the suprachiasmatic nucleus 3 months after treatment with LPS showed persistent upregulation of the microglial markers CD-11b and F4/80, but no changes in the expression of various neuropeptides, cytokines, and intracellular signallers. The effects of sepsis on circadian rhythms does not seem to be driven by cell death, as 24 hours after LPS treatment there was no evidence for apoptosis in the suprachiasmatic nucleus as judged by TUNEL and cleaved-caspase 3 staining. Overall these data provide novel insight into how septic shock exerts chronic effects on the mammalian circadian system.
