RESUMO
Background: Atazanavir and darunavir represent the main HIV PIs recommended in pregnancy, but comparative data in pregnant women are limited. We assessed the safety and activity profile of these two drugs in pregnancy using data from a national observational study. Methods: Women with atazanavir or darunavir exposure in pregnancy were evaluated for laboratory measures and main pregnancy outcomes (e.g. preterm delivery, low birthweight, non-elective caesarean section and neonatal gestational age-adjusted birthweight Z-score). Results: Final analysis included 500 pregnancies with either atazanavir (n = 409) or darunavir (n = 91) exposure. No differences in pregnancy outcomes, weight gain in pregnancy, drug discontinuations, undetectable HIV-RNA, haemoglobin, ALT, total cholesterol, HDL cholesterol and LDL cholesterol were observed between the two groups. At third trimester, exposure to darunavir was associated with higher levels of plasma triglycerides (median 235.5 versus 179 mg/dL; P = 0.032) and a higher total cholesterol/HDL cholesterol ratio (median 4.03 versus 3.27; P = 0.028) and exposure to atazanavir was associated with higher levels of plasma bilirubin (1.54 versus 0.32 mg/dL; P < 0.001). Conclusions: In this observational study, the two main HIV PIs currently recommended by perinatal guidelines showed similar safety and activity in pregnancy, with no evidence of differences between the two drugs in terms of main pregnancy outcomes. Based on the minor differences observed in laboratory measures, prescribing physicians might prefer either drug in some particular situations where the different impacts of treatment on lipid profile and bilirubin may have clinical relevance.

OBJECTIVES: The aim of the study was to assess the rate, determinants, and outcomes of repeat pregnancies in women with HIV infection. METHODS: Data from a national study of pregnant women with HIV infection were used. Main outcomes were preterm delivery, low birth weight, CD4 cell count and HIV plasma viral load. RESULTS: The rate of repeat pregnancy among 3007 women was 16.2%. Women with a repeat pregnancy were on average younger than those with a single pregnancy (median age 30 vs. 33 years, respectively), more recently diagnosed with HIV infection (median time since diagnosis 25 vs. 51 months, respectively), and more frequently of foreign origin [odds ratio (OR) 1.36; 95% confidence interval (CI) 1.10-1.68], diagnosed with HIV infection in the current pregnancy (OR: 1.69; 95% CI: 1.35-2.11), and at their first pregnancy (OR: 1.33; 95% CI: 1.06-1.66). In women with sequential pregnancies, compared with the first pregnancy, several outcomes showed a significant improvement in the second pregnancy, with a higher rate of antiretroviral treatment at conception (39.0 vs. 65.4%, respectively), better median maternal weight at the start of pregnancy (60 vs. 61 kg, respectively), a higher rate of end-of-pregnancy undetectable HIV RNA (60.7 vs. 71.6%, respectively), a higher median birth weight (2815 vs. 2885 g, respectively), lower rates of preterm delivery (23.0 vs. 17.7%, respectively) and of low birth weight (23.4 vs. 15.4%, respectively), and a higher median CD4 cell count (+47 cells/µL), with almost no clinical progression to Centers for Disease Control and Prevention stage C (CDC-C) HIV disease (0.3%). The second pregnancy was significantly more likely to end in voluntary termination than the first pregnancy (11.4 vs. 6.1%, respectively). CONCLUSIONS: Younger and foreign women were more likely to have a repeat pregnancy; in women with sequential pregnancies, the second pregnancy was characterized by a significant improvement in several outcomes, suggesting that women with HIV infection who desire multiple children may proceed safely and confidently with subsequent pregnancies.

PURPOSE: To provide information about main pregnancy outcomes in HIV-HCV coinfected women and about the possible interactions between HIV and HCV in this particular population. METHODS: Data from a multicenter observational study of pregnant women with HIV, conducted in Italian University and Hospital Clinics between 2001 and 2015, were used. Eligibility criteria for analysis were HCV coinfection and at least one detectable plasma HCV-RNA viral load measured during pregnancy. Qualitative variables were compared using the Chi-square or the Fisher test and quantitative variables using the Mann-Whitney U test. The Spearman's coefficient was used to evaluate correlations between quantitative variables. RESULTS: Among 105 women with positive HCV-RNA, median HCV viral load was substantially identical at the three trimesters (5.68, 5.45, and 5.86 log IU/ml, respectively), and 85.7 % of the women had at least one HCV-RNA value >5 log IU/ml. Rate of preterm delivery was 28.6 % with HCV-RNA <5 log IU/ml and 43.2 % with HCV-RNA >5log (p = 0.309). Compared to women with term delivery, women with preterm delivery had higher median HCV-RNA levels (third trimester: 6.00 vs. 5.62 log IU/ml, p = 0.037). Third trimester HIV-RNA levels were below 50 copies/ml in 47.7 % of the cases. No cases of vertical HIV transmission occurred. Rate of HCV transmission was 9.0 % and occurred only with HCV-RNA levels >5 log IU/ml. CONCLUSIONS: Coinfection with HIV and HCV has relevant consequences in pregnancy: HIV coinfection is associated with high HCV-RNA levels that might favour HCV transmission, and HCV infection might further increase the risk of preterm delivery in women with HIV. HCV/HIV coinfected women should be considered a population at high risk of adverse outcomes.

HIV-related acute inflammatory leukoencephalopathy of undetermined origin (AIL) is characterized by abrupt onset of symptoms generally associated with focal brain lesions and inflammatory CSF findings. A previously asymptomatic 31-year-old HIV+ woman presented with acute cognitive difficulties, right hemiparesis and dysphasia. Brain MRI showed a large contrast-enhancing lesion in the left frontal lobe; brain biopsy revealed an inflammatory process. No etiological agent was found in blood, CSF or brain tissue. The patient was given systemic steroids and gammaglobulins and put on HAART. Clinical conditions progressively and completely recovered. Further brain MRI showed the shrinkage of the lesion with no contrast enhancement. Our case could be classified as AIL in HIV resembling ADEM pattern and highlights the importance of taking into consideration. ADEM in the diagnostic process of HIV-related leukoencephalopathy even if the typical features are lacking, as immunodeficiency could modify both presentation and disease course.

Mother-to-infant transmission of Hepatitis C Virus (HCV) represents the major cause of pediatric HCV infection today. Immunogenetic influence has been poorly investigated and mainly confined to HLA-class II serological polymorphisms. Among 290 parities, 135 from Pavia and 155 from Bergamo, of HCV-RNA-infected Italian women, 21 babies (7.24%) were HCV-RNA positive at birth and steadily positive over 20 months of life. All the 21 infected babies and 44 randomly selected uninfected ones, born to HCV-RNA+ mothers but steadily negative for HCV-RNA during a follow-up of 2 years, and their mothers were investigated for HLA-G, -C, -DRB1, -DQA1 and -DQB1 genomic polymorphisms. Among the different covariates, HLA-Cw*07, -G*010401, -DRB1*0701, -DRB1*1401 and homozygosity for HLA-G 14bp deletion can be considered as risk factors for HCV vertical transmission. On the contrary, protection was conferred by the HLA-DQB1*06, -G*0105N, -Cw*0602, DRB1*1104 and -DRB1*1302 alleles. Our initial question was: has the immunogenetic profile any role in the protection of the fetus growing in an infected milieu and, if so, is it independent from the other non-immunogenetic parameters? The answer to both questions should be yes.

BACKGROUND AND AIM: Large interferon-based therapeutic trials are still lacking in children with hepatitis C and the long-term safety and efficacy of interferon is unknown. This study describes the outcome of hepatitis C in 43 children enrolled in an open-label interferon trial, and were followed up to 66 months after stopping treatment. PATIENTS AND METHODS: All patients received interferon alfa2a (5MU/m(2)) thrice weekly for 6 months; children with genotype 1b received 3MU/m(2) thrice weekly for 6 additional months. RESULTS: Nine children discontinued interferon for adverse events and three were not compliant to treatment. Eight (19%, intention to treat analysis), including 2/20 (10%) with genotype 1b and 6/12 (50%) with genotypes 2 or 3, were sustained responders 12 months after stopping therapy. During further follow-up (mean+/-S.D.: 44.7+/-14.6 months), response was maintained; two non-responders cleared viremia, while a young boy progressed to cirrhosis. CONCLUSIONS: Small sample size and therapy withdrawal are the major limitations in the interpretation of our results. Nevertheless, our data, suggesting that response to interferon in children with hepatitis C is genotype-related and stable, agree with the results of large studies in adults. The outcome in non-responders was variable, including persistence of viremia and mild-moderate cytolysis (most cases), progression to cirrhosis, or eventual sustained viremia clearance.

Early diagnosis of HIV infection in the child of an HIV-infected mother may be difficult as HIV-specific immunoglobulin (Ig) G antibodies are transmitted to the fetus transplacentally. In an attempt to provide a new, simpler tool for early identification of HIV-infected children we analysed the HIV-specific IgG subclass pattern during the first year of life. One hundred and one samples were collected from 35 children born to HIV-seropositive mothers, among whom 18 seroreverted during follow-up and 17 were HIV-infected (two P1 and 15 P2 according to the Centers for Disease Control classification). Serum HIV-specific IgG3 was detectable at least in one sample in 26 out of 35 children. All 17 HIV-infected children showed persistently detectable specific IgG3, both with stable or progressive disease. Out of the 18 uninfected children who seroreverted during follow-up, nine were HIV-specific IgG3-negative when first tested and nine lost HIV-specific-IgG3 within 28 weeks after birth. The correlation of the serological results with clinical information and any other diagnostic tool on each child suggests that the clearance of specific-IgG3 antibodies heralds seroconversion in uninfected passive antibody-carrier children. This observation provides the basis for a new, simple and effective method for early diagnosis of HIV infection in children born to seropositive mothers.

OBJECTIVE: To investigate the role of maternal HIV-1 isolate phenotype and a child's cell susceptibility/resistance to viral infection in mother-to-child HIV-1 transmission. PATIENTS AND METHODS: Forty-nine women were studied at the time of delivery. Primary isolates, obtained by culturing patient peripheral blood mononuclear cells (PBMC) with PBMC from healthy donors, were characterized for tropism and syncytium-inducing capability in monocyte-derived macrophages (MDM), peripheral blood lymphocytes (PBL), and in the MT-2 and MOLT-3 T-cell lines. RESULTS: Seven women transmitted HIV-1 to their children. Primary isolates were obtained from six and 28 transmitting and non-transmitting mothers, respectively. All primary isolates from transmitting mothers and their infants but only 50% of those from non-transmitting mothers replicated in MDM, regardless of their replication capacity in T-cell lines. PBL and MDM cells from six uninfected children were exposed to the corresponding maternal isolates. Polymerase chain reaction analysis of HIV-1 DNA in cells and p24 antigen assay in culture supernatants disclosed that two PBL and five MDM cultures were resistant to viral infection; two other PBL cultures, although HIV-1-infected, were negative for p24 production. Depletion of CD8+ cells only partially restored productive infection in CD4+ cell cultures. Moreover, all six PBL but only one MDM cultures were productively infected by an isolate obtained from a transmitting mother, thus suggesting that MDM resistance to HIV-1 infection is not viral isolate-restricted. CONCLUSIONS: Our findings strongly suggest that mother-to-child HIV-1 transmission is influenced by both monocyte-macrophage tropism of the maternal isolate and susceptibility of the child's target cells, in particular monocyte-macrophages, to HIV-1 infection.

OBJECTIVE: To evaluate the circadian secretion of hormones involved in the regulation of growth in childhood, namely growth hormone, insulin-like growth factor (IGF)-I, cortisol, adrenocorticotropin hormone (ACTH), and thyroid-stimulating hormone (TSH) in HIV-infected children. DESIGN: The circadian secretory pattern of growth hormone, IGF-I, cortisol, ACTH and TSH was evaluated in 14 HIV-infected children; 13 healthy age- and sex-matched children were chosen as controls. METHODS: Sampling was performed every 4 h from 0400 h to 2000 h and every 2 h from 2000 h to 0400 h. Rhythmometric data were analysed by single and population mean cosinor methods and by analysis of variance. RESULTS: A statistically significant circadian rhythm for growth hormone, IGF-I and cortisol was detectable in HIV-seropositive children, but the mean basal IGF-I levels were below the normal range for age in 12 patients. A statistically significant circadian rhythm was not detectable for ACTH or TSH. CONCLUSION: These results show that there is a loss of the physiological regulation of growth hormone-IGF-I axis and a modification of 24 h TSH profile in our HIV-infected children. These abnormalities might be involved in the altered growth mechanism leading to the failure to thrive that is a peculiar feature of HIV-infected children.

HIV infected children characteristically develop a failure to thrive in 25% to 100% of symptomatic cases, with a significantly reduced survival time. The pathogenic mechanism for HIV-driven failure to thrive is not yet understood. Likely it is multifactorial, endocrine dysregulation surely plays a major, even if not yet fully clarified, role in this complication. Global evaluation of endocrine data could allow to better understand the mechanisms underlying the failure to thrive in HIV-infected children, also in relationship with the current manifestations of the HIV infection. The results of the endocrine studies could also be related with additional features of the children, as their immunological status. It is well known that endocrine and immune functions are closely related in animals and in humans. Thus, the evaluation of the results of studies could provide some interesting information about the relationships between them in the HIV-infected child. Such relationships, if present, also could help to better define therapeutic interventions in these children.

The prevalence of lower genital neoplasia and Human Papilloma-virus-related genital lesions were evaluated in a cohort of 75 women with Human Immunodeficiency Virus type 1 (HIV-1) infection at different stages of HIV disease. The overall rate of cervical intraepithelial neoplasia (CIN) in the group studied was 29.3% (22/75). Eight out of 10 high-grade CIN lesions contained 'high-risk' HPV-DNA 16/18 and/or 31/35/51 as demonstrated by 'in situ' hybridization with biotinylated probes. Vulvar and/or perianal condylomata were histologically diagnosed in 14 patients (18.7%); nine of these biopsies contained detectable HPV-DNA which was always related to HPV 6/11. The rate of high-grade CIN in symptomatic HIV-infected patients was 28% (7/25) as compared to 6% (3/50) of the other cases (P = 0.022). CD4 lymphocyte counts, white blood cell counts, CD4+/CD8+ cell ratio and percentage of CD4+ lymphocytes were lower in patients with high-grade CIN in comparison to the patients with negative colposcopical and/or cytological examination. After adequate standard treatment (cryotherapy, electrocauterization, cold-knife conization) only one case of CIN 2 recurred during the 2 years of follow-up period. The prevalence of lower genital neoplasia and HPV-related lesions among HIV-infected women is high and seems to correlate with the severity of HIV disease.

In a prospective longitudinal 10-year (1988 to 1998) study, 308 sequential blood samples from 218 infants born to HIV-1 seropositive women were examined by blood culture, polymerase chain reaction (PCR) and Western Blot (WB) for HIV-1 infection within the first month of life (no. 47 specimens), at 2-6 (no. 125), 7-18 (no. 80), and > 18 (no. 56) months after birth. Clinical status at follow-up after the initial diagnosis of HIV infection was also evaluated. Vertically transmitted HIV infection was diagnosed in 45 children (24 children were diagnosed before 18 months of age), whereas 173 were found to be uninfected (transmission rate 20.6%). Sensitivities of viral culture, PCR and WB were 95.2%, 97.8%, 94.4%, and specificities were 99.5%, 97.6% and 20.7%, respectively. Thus, cumulative positive predictive values (PPV) of blood culture, PCR and WB were 97.5%, 88.2% and 23.4%, while negative predictive values (NPV) were 99.0%, 99.6% and 100.0%, respectively. In view of defining the optimal time of sampling for a correct diagnosis of HIV infection, a PPV of 100.0% was achieved earlier by viral culture (2-6 months of age) than by PCR (7-18 months of age). Meanwhile, a NPV of 100% was obtained earlier by PCR (within the first month of age) than by viral culture (2-6 months). These results indicate that a combination test strategy requiring two blood samples analyzed by viral culture and PCR may confirm or exclude HIV perinatal infection within the first 2 months of life rather than being delayed to later times. Clinical follow-up was performed in 35 children, of whom 7 developed a rapidly progressive disease, 23 showed a slow progression, while 5 children are still younger than 5 years and do not present severe clinical symptoms.

Opportunistic mycotic infections have a significant influence on the morbidity and mortality of children whose immune systems are depressed by the onset of AML. The present paper assesses the incidence of the pathogenic mycotic flora and the in vitro efficacy of the main antimycotic drugs. Candida was che most commonly encountered pathogen and its in vitro response to the polyenic antibiotics was good.

Three cases of aspergillosis observed in Pavia Infectious Disease Clinic in 1983-85 are described. The cases differed both in the site of the infection (lungs, bones and liver) and in the patients' basic immunological situation. The importance of mycological investigations during diagnosis is emphasised, though they should of course be flanked by instrumental examinations and blood chemical assays. The efficacy of specific treatment with amphotericin B combined with surgery and plasma exchange is also emphasised.

Since the introduction of antibiotic treatment there has been a remarkable reduction in the incidence of "classical" neurosyphilis, and, when cerebral involvement occurs, a relative increase in abortive or monosymptomatic cases that are difficult to diagnose because of the prevalence of meninges and/or mental signs. A case of luetic meningoencephalitis is described with emphasis on diagnostic, prognostic and therapeutic aspects.

The present study describes a case of AIDS with asymptomatic intracranial focal lesions. The DDD-enhancement CT technique detected the lesions as inflammatory or neoplastic. A subsequent MR demonstrated the vascular nature of the intracranial findings. MR in the neuropathology of AIDS can be of primary importance in the detection of the intracranial focal lesions, thus avoiding a cerebral stereotaxic needle biopsy.

We report the follow-up and treatment of HCMV infections in three patients with AIDS. The patients, affected by HCMV retinitis, have been followed 24, 12 and 6 months respectively. The antiviral treatment was based on the DHPG administration which was substituted in one case of resistance to DHPG with Foscarnet. In the follow-up period, virological tests have been performed to detect the presence of the HCMV antigenemia/viremia. The results show that, to avoid the progression of the retinitis, the antiviral treatment must not be stopped or discontinued. DHPG and Foscarnet were able to limit the infection to the eye and were well tolerated. In the HCMV-infected patients, the continuous monitoring of the antigenemia/viremia is of main importance to follow the clinical and therapeutical course of the disease.

Since the introduction of antibiotic therapy, the incidence of intra- and extracranial suppurative complication of acute and chronic purulent otitis media has sharply decreased. In particular, reports of laterocervical abscesses secondary to this disorder are quite rare, not more than twenty cases of Bezold's or Mouret's abscesses having been reported in the literature during the last ten years. The authors present a case of retropharyngeal and Mouret's abscess developed as a consequence of acute purulent otitis media in a young Aids patient. True otologic manifestations of Aids are rare while the incidental association of otologic disease with Aids is more common. The development of complication in the present case is favoured by the patients severe immunodepression.
