Abstract
AIMS Patients with Crohn's disease (CrD) have an elevated risk for the development of small bowel adenocarcinomas (SBAs). Actionable isocitrate dehydrogenase 1 (IDH1) mutations have been reported to be more frequent in CrD-SBAs than in sporadic SBAs. The present study aimed to investigate the clinicopathological and immunophenotypical features, as well as methylation profiles, of IDH1-mutated CrD-SBAs. METHODS AND RESULTS An international multicentre series of surgically resected CrD-SBAs was tested for IDH1 mutation. Clinicopathological features, immunophenotypical marker expression and O6-methylguanine-DNA methyltransferase (MGMT) and long interspersed nuclear element-1 (LINE-1) methylation were compared between IDH1-mutated and IDH1 wild-type CrD-SBAs. Ten (20%) of the 49 CrD-SBAs examined harboured an IDH1 mutation and all the mutated cancers harboured the R132C variant. Compared to IDH1 wild-type cases, IDH1-mutated CrD-SBAs showed significantly lower rates of cytokeratin 7 expression (P = 0.005) and higher rates of p53 overexpression (P = 0.012) and MGMT methylation (P = 0.012). All three dysplastic growths associated with IDH1-mutated SBAs harboured the same IDH1 variant (R132C) of the corresponding invasive cancer, and all were of non-conventional subtype (two serrated dysplastic lesions and one goblet cell-deficient dysplasia). In particular, non-conventional serrated dysplasia was significantly associated with IDH1-mutated CrD-SBAs (P = 0.029). No significant cancer-specific survival difference between IDH1-mutated CrD-SBA patients and IDH1 wild-type CrD-SBA patients was found (hazard ratio = 0.55, 95% confidence interval = 0.16-1.89; P = 0.313). CONCLUSIONS IDH1-mutated CrD-SBAs, which represent approximately one-fifth of total cases, are characterised by distinctive immunophenotypical features and methylation profiles, with potential therapeutic implications. Moreover, IDH1-mutated non-conventional, serrated dysplasia is likely to represent a precursor lesion to such CrD-SBAs.

Abstract
The gastrointestinal (GI) tract is the most common extranodal site of occurrence of non-Hodgkin lymphomas. Most GI lymphomas are of B-cell lineage, while T-cell lymphomas are less frequent. The aim of our retrospective study was to depict the clinical-pathological profile of a series of patients affected by intestinal T-cell lymphomas (ITCL) and possibly define hallmarks of these neoplasms. A total of 28 patients were included: 17 enteropathy-associated T-cell lymphomas (EATL), 5 monomorphic epitheliotropic T-cell lymphomas (MEITL), 3 indolent T-cell lymphoproliferative disorders of the gastrointestinal tract (ITCLDGT), and 3 intestinal T-cell lymphomas not otherwise specified (ITCL-NOS). Celiac disease (CD) was diagnosed in around 70% of cases. Diagnosis of EATL showed a significant correlation with CD30 expression, whereas MEITL with angiotropism and CD56 positivity. ITCLDGT cases showed plasma cells infiltration. Peripheral lymphocytosis, the absence of a previous diagnosis of CD, an advanced Lugano clinical stage, and the histological subtype ITCL-NOS were significantly associated with worse survival at multivariate analysis. Our findings about the epidemiological, clinical, and histopathological features of ITCL were in line with the current knowledge. Reliable prognostic tools for these neoplasms are still lacking but according to our results lymphocytosis, diagnosis of CD, Lugano clinical stage, and histological subtype should be considered for patient stratification.

Abstract
Objectives Pregnancy in SSc is burdened with an increased risk of obstetric complications. Little is known about the underlying placental alterations. This study aimed to better understand pathological changes and the role of inflammation in SSc placentas. Leucocyte infiltration, inflammatory mediators and atypical chemokine receptor 2 (ACKR2) expression in SSc placentas were compared with those in other rheumatic diseases (ORD) and healthy controls (HC). Methods A case–control study was conducted on eight pregnant SSc patients compared with 16 patients with ORD and 16 HC matched for gestational age. Clinical data were collected. Placentas were obtained for histopathological analysis and immunohistochemistry (CD3, CD20, CD11c, CD68, ACKR2). Samples from four SSc, eight ORD and eight HC were analysed by qPCR for ACKR2 expression and by multiplex assay for cytokines, chemokines and growth factors involved in angiogenesis and inflammation. Results The number of placental CD3, CD68 and CD11 cells was significantly higher in patients affected by rheumatic diseases (SSc+ORD) compared with HC. Hepatocyte growth factor was significantly increased in the group of rheumatic diseases patients (SSc+ORD) compared with HC, while chemokine (C-C motif) ligand 5 (CCL5) was significantly higher in SSc patients compared with ORD and HC. CCL5 levels directly correlated with the number of all local inflammatory cells and higher levels were associated with histological villitis. Conclusions Inflammatory alterations characterize placentas from rheumatic disease patients and could predispose to obstetric complications in these subjects.

Abstract
Bronchiolitis Obliterans Syndrome seriously reduces long-term survival of lung transplanted patients. Up to now there is no effective therapy once BOS is established. Nanomedicine introduces the possibility to administer drugs locally into lungs increasing drug accumulation in alveola reducing side effects. Imatinib was loaded in gold nanoparticles (GNP) functionalized with antibody against CD44 (GNP-HCIm). Lung fibroblasts (LFs) were derived from bronchoalveolar lavage of BOS patients. GNP-HCIm cytotoxicity was evaluated by MTT assay, apoptosis/necrosis and phosphorylated-cAbl (cAbl-p). Heterotopic tracheal transplantation (HTT) mouse model was used to evaluate the effect of local GNP-HCIm administration by Alzet pump. GNP-HCIm decreased LFs viability compared to Imatinib (44.4 ± 1.8% vs. 91.8 ± 3.2%, p < 0.001), inducing higher apoptosis (22.68 ± 4.3% vs. 6.43 ± 0.29; p < 0.001) and necrosis (18.65 ± 5.19%; p < 0.01). GNP-HCIm reduced cAbl-p (0.41 GNP-HCIm, 0.24 Imatinib vs. to control; p < 0.001). GNP-HCIm in HTT mouse model by Alzet pump significantly reduced tracheal lumen obliteration (p < 0.05), decreasing apoptosis (p < 0.05) and TGF-β-positive signal (p < 0.05) in surrounding tissue. GNP-HCIm treatment significantly reduced lymphocytic and neutrophil infiltration and mast cells degranulation (p < 0.05). Encapsulation of Imatinib into targeted nanoparticles could be considered a new option to inhibit the onset of allograft rejection acting on BOS specific features.

Abstract
Mixed histiocytoses are a rare and recently recognized subset of histiocytic disorders that may involve the skin, characterized by the synchronous or metachronous development of lesions with Langerhans and/or non-Langerhans cell histiocytosis histopathological features. Around 10% of patients diagnosed with histiocytosis may develop a hematological malignancy, often with dramatic prognostic consequences. We hereby describe the exceptional case of a patient developing a MAP2K1-driven mixed histiocytosis with Langerhans cell histiocytosis, Rosai-Dorfman-Destombes disease, and Erdheim-Chester disease features and cutaneous involvement, progressing to a fatal and clonally-related acute myeloid leukemia. We reviewed the literature on similar cases and discussed the histopathological difficulties in their diagnosis and their clinical-pathological features.

Abstract
The increasing incidence of HPV-related oropharyngeal squamous cell carcinoma (OPSCC) observed in several developed countries has not yet been documented in Italy. To investigate changes in the epidemiology of HPV-related OPSCC we reviewed the HPV status of cases evaluated at our centre in northern Italy before and after 2010. The results were correlated with patient age, sex, oropharyngeal subsite (classified as palatine tonsil, tongue base, palatine arch/palate/uvula, posterior oropharyngeal wall, and oropharynx not otherwise specified), AJCC tumour stage, risk factor exposure (smoke, alcohol), disease history (recurrence, metastasis, second tumours), outcome and survival. Positivity for p16 and HR HPV DNA was required to classify HPV-related OPSCC. HPV-related tonsillar OPSCC increased significantly after 2010, while a non-significant reduction of HPV-related extra-tonsillar OPSCC was observed. Non-keratinising morphology was strongly associated with HPV positivity. HPV16 was the most common genotype; the frequency of other high-risk genotype infections decreased after 2010. At multivariate analysis, HPV status showed a significant association with better outcome. We documented an increase of HPV-related OPSCC in our Italian population, synchronous with the increase observed in several Western countries, which in recent years reached a prevalence similar to that reported in central European countries. Our results indicate that HPV infection in head and neck oncology is relevant in Italy and needs to be considered for accurate patient stratification.

Abstract
BACKGROUND Jejunal free flap (JFF) reconstruction is a popular treatment option for advanced hypopharyngeal cancer. Several factors including ischemia-reperfusion injury (IRI) can cause mucosal damage and progressive flap necrosis. We investigated the development and time-related progression of morphological and cellular changes in patients with JFF reconstruction including cold preservation of the graft. METHODS Eleven patients were enrolled. Biopsies were taken during surgery from normally perfused tissue, before loop isolation (T0), at the end of back-table surgery (T1), immediately before reperfusion (T2), 15' after reperfusion (T3), and at the end of the digestive anastomoses (T4) and from the external monitor daily from the 1st to the 5th postoperative day (M1-M5). Histomorphological and immunohistochemical parameters in the intraoperative and postoperative samples were evaluated and compared. RESULTS Delayed flap necrosis was observed in 2 patients. The cold ischemia phase did not negatively affect mucosal regeneration after reperfusion; morphological and cellular damage parameters returned to normal by the end of surgery or along the early postoperative period. Significant enterocyte replication activity was observed at the end of revascularization, which continued in the postoperative phase, leading to recovery of the epithelial morphological integrity and disappearance of apoptotic cells. An inflammatory infiltrate persisted in the M samples, and in a significant proportion of samples, mucosal fibrosis developed by the end of the postoperative observation. CONCLUSION Cold perfusion and preservation of the JFF can effectively limit the negative effects of IRI and to prevent short- and medium-term complications that can compromise the final outcome.

Abstract
In 2015, Lewis et al. first described low-grade papillary Scheneiderian carcinoma (LGPSC) of the sinonasal tract. Their case resembled a sinonasal papilloma clinically and histopathologically; however, invasion and metastasis resulted in the death of the patient despite absence of malignant cytologic features. Additional reports established LGPSC as a distinct entity and characterized its immunohistochemical profile. Diffuse expression of low molecular weight cytokeratins, positivity for p16 and p53 in at least 50% of cells, a high Ki-67 index, and absence of human papillomavirus (HPV)-DNA was observed across all reported cases. We report an additional case of LGPSC and describe the clinical, histologic, and immunohistochemical features. In contrast to sinonasal papillomas, the case was negative for HPV-DNA and showed no mutations in the EGFR and KRAS hotspot regions.

Abstract
In geographical areas with a low incidence of tuberculosis, recurrent tuberculosis is generally due to reactivation of the disease. However, the relative contribution of tuberculosis reinfection increases in parallel with the incidence of disease and is likely to depend on the epidemiological context: factors such as the spread of multidrug resistance, human immunodeficiency virus (HIV) infection, and immigration from developing countries could modify disease transmission in areas at low risk for tuberculosis. A molecular epidemiology study was performed in Lombardy, Northern Italy, where the incidence of tuberculosis is 17.5 cases per 100,000 persons. A total of 2,452 cases of culture-confirmed tuberculosis in 2,127 patients were studied. A group of 32 patients (1.5%), each of whom had two episodes of tuberculosis with cure as the outcome of the first episode and with more than 6 months between the two episodes, were studied by means of restriction fragment length polymorphism DNA fingerprinting analysis. For 5 of the 32 patients (16%), the DNA fingerprinting patterns of Mycobacterium tuberculosis strains responsible for the second episode did not match those of the corresponding isolates of the first episode, indicating exogenous reinfection. Two of these patients developed multidrug-resistant tuberculosis during the second episode, and in three cases the isolates belonged to clusters of M. tuberculosis strains spreading in the community. A fourfold-increased risk for reinfection was observed in immigrant patients compared to Italian subjects. In contrast, a higher risk of relapse rather than reinfection was evidenced in HIV-positive subjects and in patients infected with multidrug-resistant tuberculosis. Episodes of tuberculosis reinfection in areas with a low incidence of tuberculosis are rare compared to those in high-incidence geographical regions. In populations that have immigrated from high-risk areas, reinfection may represent a considerable contributor to the rate of recurrent tuberculosis. This finding emphasizes the importance of containing the spread of epidemic strains in close communities, in order to prevent changes in global tuberculosis trends for developed countries.

Abstract
We evaluated the sensitivity of a DNA amplification test for the detection of Mycobacterium avium in blood samples using different blood components and different DNA extraction methods. M. avium-inoculated blood samples were processed to obtain separate blood components: peripheral blood mononuclear cells (PBMCs), polymorphonuclear cells (PMNCs), and whole-blood sodium dodecyl sulfate (SDS)-lysate pellets. The sensitivity for the detection of the lowest mycobacterial load (1 CFU/ml) was significantly greater (P < 0.01) with DNA extracted from SDS-lysate pellets than with DNA extracted from PBMCs or PMNCs. Subsequently, DNA extraction methods based on guanidine NaOH, and proteinase were compared. The sensitivity of the guanidine-based method was significantly greater (P < 0.01) than those of the others.

Abstract
BACKGROUND Atrial fibrillation (AF) is the most frequent complication following cardiac surgery. It occurs mostly between the second and fourth postoperative days and often recurs within 30 days after surgery. While postoperative AF has been well analyzed, post-discharge recurrences of AF have not been clearly described even if they are reported as a frequent cause of re-hospitalization. METHODS We followed up 185 patients for 10 +/- 5 months with the aim of characterizing the post-discharge recurrences of AF. All patients had recently undergone cardiac surgery complicated by AF and were in sinus rhythm at the time of admission to our Center. We also compared the efficacy of the main prophylactic regimens adopted in the referral Centers (amiodarone, beta-blockers, amiodarone plus beta-blockers) during the first postoperative month. RESULTS In the first postoperative month AF recurred after discharge in 60 patients. The event rate was not different in patients treated with amiodarone and controls (47 vs 50%, p = NS), while it was significantly lower in patients taking beta-blockers either alone or associated with amiodarone (10 and 9% respectively, p = 0.002). At the end of follow up (10 +/- 5 months), AF persisted in 3 out of 176 study patients (1.7%). CONCLUSIONS In patients undergoing cardiac surgery, post-discharge recurrences of AF are frequent during the first postoperative month and have a clinical relevance. Beta-blockers (not amiodarone) seem to be an effective prophylactic measure. The phenomenon tends to vanish in the long term, and a chronic prophylaxis is not justified.

Abstract
Differentiation between Mycobacterium tuberculosis and M. avium is essential for the treatment of mycobacterial infections. We have developed an easy and rapid detection assay for the diagnosis of mycobacterial diseases. This is a PCR-hybridization assay based on selective amplification of a 16S rRNA gene sequence using pan-Mycobacterium primers followed by hybridization of the amplification products to biotinylated M. tuberculosis and M. avium-specific probes. A total of 55 mycobacterial isolates were tested. For all isolates, results concordant with those of conventional identification methods were obtained. Moreover, we developed a method for extraction of DNA from Ziehl-Neelsen-positive smears which allows the recovery of intact target DNA in our PCR-hybridization assay. Our method was able to confirm all culture results for 59 Ziehl-Neelsen-positive smears from clinical specimens (35 sputum, 11 lymph node biopsy, 6 stool, 4 pus, 2 urine, and 1 pericardial fluid specimens). These data suggest that our PCR-hybridization assay, which is simple to perform and less expensive than commercial probe methods, may be suitable for the identification of M. tuberculosis and M. avium. It could become a valuable alternative approach for the diagnosis of mycobacterial infections when applied directly to DNA extracted from Ziehl-Neelsen-positive smears as well.

Abstract
The production of nitric oxide (NO) by macrophages is important for the killing of intracellular pathogens, such as Toxoplasma gondii. Gamma interferon (IFN-gamma) and lipopolysaccharide stimulate NO production. The aim of this study was to investigate the importance of NO, IFN-gamma and interleukin-12 (IL-12) in the host immune response in AIDS patients suffering from toxoplasmic encephalitis (TE). It was demonstrated that the production of NO, detected as nitrite/nitrate in the sera and in the cerebrospinal fluid (CSF) of 32 AIDS patients with TE, was normal. In addition, levels of IFN-gamma in the sera and in the CSF of patients with TE were not increased. In contrast, serum levels of IL-12 in these patients were significantly increased (6.5 +/- 7.1 pg/ml; P = 0.0368), compared to the control patients (1.7 +/- 3.5 pg/ml). Furthermore, increased but not significant levels of IL-12 were also observed in the CSF of patients with TE (2.2 +/- 4.7 pg/ml; controls: 0.5 +/- 1.9 pg/ml). The results of this study indicate that reactivation or recurrence of T. gondii infection in HIV-1-infected patients is probably due to a down-regulation of IFN-gamma along with a resulting non-optimal NO activity.

Abstract
The aim of this pilot study was twofold. The first was to show a method for having an objective and dynamic analysis of body posture, evaluating weight distribution and its connections with different mandibular positions. The second was to verify if a neuromuscularly stimulated occlusal position, called myocentric occlusal position, is associated with a positive or negative postural charge. For the second aim a group of 20 subjects (including both males and females), was chosen. Posture of each subject was analyzed in three different conditions: centric occlusion, rest position and myocentric position. To evaluate the dynamic of posture a platform capable of measuring the weight on the feet supporting points and the related variations during time of observation and the swinging of body barycenter was used. The data showed that there is an improvement in the position of the barycenter from the centric occlusion to the myocentric position. Such an improvement can't be observed from the intercuspal position to the rest position. The results of this pilot study are discussed.

Abstract
The purpose of this study was to evaluate nitric oxide (NO) activity in patients with uncomplicated malaria. Lipopolysaccharide and gamma interferon (IFN-gamma) are potent inducers of NO by inducing production of NO synthase. NO activity was determined by measuring serum levels of nitrite/nitrate (metabolic end products of NO), and IFN-gamma in patients with uncomplicated malaria, mostly caused by Plasmodium falciparum. Neither serum levels of nitrite/nitrate nor of IFN-gamma were significantly increased in patients with uncomplicated malaria, especially in patients with P. falciparum infection, and in those with high parasitaemia. These results show that NO cannot play a role in uncomplicated malaria, and it is still debatable if NO production in this infection has beneficial or detrimental effects.

Abstract
Nitric oxide is produced in large amounts during host defense and immunological reactions and it is likely to have a role in non-specific immunity: nitric oxide exerts microbiostatic and microbicidal activity against a variety of pathogens, including protozoa, fungi, bacteria and some viruses. HIV-1 stimulates nitric oxide production by human macrophages and its production is increased in patients with HIV-1 infection. It is postulated that nitric oxide may play a part in modulating the immune response during HIV-1 infection. Nitric oxide produced by the HIV-1 infected monocytes/macrophages of lymph nodes, may adversely affect the survival of activated immune cells, including B and T lymphocytes and dendritic cells within their vicinity. It is suggested here that production of large amounts of nitric oxide by macrophages may lead to the inactivation of lymphocytes and thus to the induction of a persistent immunosuppression.

Abstract
The recombinant cytokines interferon (IFN)-gamma and interleukin (IL)-12 stimulate several macrophage-mediated functions that are important in host defense. An experimental pertussis model showed that intraperitoneal (i.p.) administration of 10,000 U of recombinant murine (rm) IFN-gamma to mice at the time of Bordetella pertussis infection caused a marked and significant reduction in the number of colony-forming units of bacteria in the lungs. Administration i.p. of 1 microgram of rmIL-12 or 1 microgram of rmIL-12 at the time of and for 5 consecutive days after B. pertussis challenge also induced a significant reduction in the number. However, i.p. administration of 1 microgram of rmIL-12 with 10,000 U of IFN-gamma at the time of B. pertussis challenge did not provide protection. These findings indicate that exogenous administration of rmIL-12 and rmIFN-gamma enhances resistance of mice to B. pertussis infection.

Abstract
AIMS To evaluate the expression of the alpha 5 beta 1 integrin fibronectin receptor (FNR), which mediates several processes, including phagocytosis, cell motility and the immune response, on T lymphocytes of patients with HIV-1 infection. METHODS T lymphocytes were incubated with monoclonal antibody directed against FNR and then with monoclonal antibodies, conjugated with phycoerythrin, directed against CD3, CD4 and CD8 positive cells. Expression of FNR on CD3, CD4 and CD8 positive cells was analysed using flow cytometry. RESULTS Normal expression of FNR was observed on CD3 positive cells from asymptomatic HIV positive patients and those with AIDS. Increased expression of FNR was observed on CD8 positive cells from asymptomatic HIV positive patients and on CD4 positive cells from patients with AIDS. Increased FNR expression was observed on CD4 positive cells from patients with AIDS, particularly those with opportunistic infections caused by Pneumocystis carinii, Mycobacterium sp, Toxoplasma gondii, and Cryptococcus neoformans. CONCLUSION Increased expression of FNR on CD8 and CD4 positive cells in asymptomatic HIV positive patients and those with AIDS, respectively, may be an epiphenomenon correlated with lymphocyte activation by HIV-1 or opportunistic infection, Further study is required to determine whether upregulation of FNR expression has a direct role in the pathogenesis of AIDS.

Abstract
AIMS To measure circulating concentrations of nitrite in patients with HIV-1 infection. METHODS Nitrite concentrations were measured using the Griess reaction adapted to microtitre plates in the serum of 10 asymptomatic HIV-1 positive patients, 33 patients with AIDS with cerebral disorders, 17 patients with AIDS with pulmonary involvement, and in eight patients with AIDS with other disorders. Nitrite concentrations were also measured in bronchoalveolar lavage (BAL) fluid and cerebrospinal fluid (CSF) of patients with AIDS with pulmonary involvement and cerebral disorders, respectively. RESULTS Increased serum concentrations of nitrite were observed in patients with pulmonary involvement, and in particular in serum and in BAL samples of patients with interstitial pneumonia (36.2 (26.2) mumol/l and 0.3 (0.4) mumol/l, respectively). Increased serum concentrations of nitrite were also noted in patients with retinitis caused by infection with cytomegalovirus. Serum nitrite concentrations were also raised in patients with cerebral toxoplasmosis, whereas normal serum concentrations were found in patients with HIV-1 encephalopathy and cryptococcal meningitis. Nitrite concentrations in CSF were not raised in patients with cerebral disorders. CONCLUSIONS These results suggest that production of nitrite in patients with AIDS with concomitant opportunistic infections may be part of the host defense against opportunistic organisms.

Abstract
Nitric oxide (NO) is a newly discovered gas that plays an important role in cell communication and host resistance to infection. The production of NO was examined in the sera of seven children infected with human immunodeficiency virus type 1 (HIV-1) and in the sera of 14 children who became seronegative for HIV-1 during the first year of life. In addition, we determined serum levels of various cytokines, such as interleukin (IL)-1 beta, tumor necrosis factor (TNF)-alpha, and gamma interferon (IFN-gamma), inasmuch as these cytokines are potent inducers of NO production. Production of NO, detected as circulating serum levels of nitrite, was measured with use of the Griess reagent. Serum levels of cytokines were determined by enzyme immunoassay. Increased serum levels of nitrite were observed in children with HIV-1 infection (0.4 +/- 0.2 mumol/L; P = .013), and in those who became seronegative for HIV-1 during the first year of life (0.5 +/- 0.3 mumol/L; P = .04). Furthermore, serum levels of IL-1 beta and TNF-alpha were significantly elevated in children with HIV-1 infection (37.5 +/- 23.6 pg/mL and 91.2 +/- 45.1 pg/mL, respectively). Prophylactic administration of intravenous immune globulin provoked a significant decrease of circulating levels of nitrite in children with HIV-1 infection. In conclusion, NO may play a role as a cytostatic or cytotoxic factor for invading microorganisms, and thus it is probably involved in limiting and/or eradicating infection.

Abstract
Nitric oxide (NO) exhibits potent antimicrobial activity in vitro. The function of NO in host defenses in vivo, however, is presently unclear. Experiments were undertaken to determine the production of NO in vitro from murine peritoneal and alveolar macrophages, and murine macrophage cell line (J774A.1) stimulated with Bordetella pertussis or pertussis toxin (PT). In addition, we determined circulating levels of NO in the sera and bronchoalveolar lavage (BAL) fluids of mice infected intranasally with B. pertussis. The results of this study showed that in vitro murine peritoneal macrophages induce production of NO in response to B. pertussis and PT. In addition, murine macrophage cell line, J774A.1 also induces NO production after stimulation with B. pertussis. NO production was also detected in alveolar macrophages from mice infected intranasally with B. pertussis. Finally, a significant increment of circulating levels of NO was noted, in the sera but not in the BAL fluids, of mice infected intranasally with B. pertussis.

Abstract
AIM To determine concentrations of fibronectin and fibronectin receptor in children with pertussis. METHODS Concentrations of circulating fibronectin and serum fibronectin receptor were detected in eight children affected by pertussis, eight children with acute upper or lower respiratory tract infections, and in 14 healthy control children. The single radial immunodiffusion technique and a solid phase enzyme immunoassay were used to detect circulating serum concentrations of fibronectin and fibronectin receptor. RESULTS On admission, a significant decrease in fibronectin was detected in children with pertussis (p = 0.0006). Significant and decreased concentrations of fibronectin were also observed in children with upper or lower respiratory tract infections (p = 0.0002). On the other hand, serum fibronectin receptor concentrations were significantly increased in patients with pertussis, whereas patients with upper or lower respiratory tract infections had normal circulating fibronectin receptor concentrations. CONCLUSIONS Fibronectin deficiency in children with pertussis may be related to diffusion and deposition of this protein in bronchial and alveolar spaces to limit infection, while increased fibronectin receptor concentrations are probably the expression of T cell activation and cell-mediated immunity during Bordetella pertussis infection.

Abstract
Several studies have demonstrated that Bordetella pertussis has the ability to enter and survive intracellularly within human polymorphonuclear leukocytes (PMNL) and human monocytes/macrophages. The effects of human recombinant gamma interferon (IFN-gamma) on the survival of B. pertussis in PMNL and human monocytes, and on the oxidative burst activity of PMNL and human monocytes in response to B. pertussis were assessed in this study. IFN-gamma partially increased intracellular killing of phagocytosed B. pertussis in human monocytes, as determined by an orange acridine-crystal violet assay. In contrast, IFN-gamma did not enhance intracellular killing of B. pertussis in PMNL. No significant increase of superoxide production was noted in human monocytes in response to B. pertussis when stimulated with various concentrations of IFN-gamma. The partial increase of B. pertussis killing by IFN-gamma within monocytes, together with poor production of superoxide may explain how B. pertussis can survive within human phagocytic cells, and thus cause a more prolonged course of the disease.

Abstract
Meningeal involvement in leptospiral infection is quite common, usually mild and often overlooked. In contrast, cases of isolated involvement of the central nervous system, including aseptic meningitis, have been reported only rarely. A case of a patient with acute aseptic meningitis caused by Leptospira australis serovar bratislava is reported. This is believed to be the first report of aseptic meningitis due to Leptospira australis. This case indicates the need to consider human leptospirosis in the differential diagnosis of aseptic meningitis.

Abstract
We found a significant increase in fibronectin receptor (FNR) levels in the sera of adult human immunodeficiency virus type 1 (HIV-1)-infected patients, especially in those with AIDS (1,026.9 +/- 583.9 ng/ml; P < 0.0001). In contrast, AIDS patients with neurologic disorders and HIV-1-seropositive patients showed normal levels of FNR in serum. In addition, HIV-1-infected children showed increased levels of FNR in serum (824.4 +/- 333.5 ng/ml; P = 0.03). We suggest that an increase of FNR levels in AIDS patients is related to enhanced expression of FNR on HIV-1-infected cells.

Abstract
Serum levels of interleukin-1 alpha (IL-1 alpha), interleukin-1 beta (IL-1 beta), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-alpha) in patients with acute viral hepatitis were investigated. Twelve patients suffering from acute viral hepatitis were studied; 8 patients presented with acute hepatitis B, 2 patients with acute hepatitis A, and 2 patients with acute hepatitis C. Serum levels of IL-1 alpha, IL-1 beta, IL-6, and TNF-alpha were significantly increased in all patients with acute viral hepatitis. Decreased serum levels of all cytokines were noted in four patients with acute hepatitis B during the recovery phase of infection. In addition, IL-1 alpha, IL-1 beta, IL-6, and TNF-alpha were undetectable at the end of a follow-up period of 6 months. Our study shows that increased levels of IL-1 alpha, IL-1 beta, IL-6, and TNF-alpha are probably related to hepatitis activity and thus may have some role in hepatocytic injury.

Abstract
Fibronectin (FN) is present in soluble and matrix forms in various body fluids and tissues, and has been shown to bind to several pathogens, including viruses. The interaction of FN with viral proteins of human immunodeficiency virus (HIV-1) was investigated by immunofluorescence technique using a cell line chronically infected with HIV-1 (H9-V). The results of this study showed that FN binds to HIV-1 infected cells, especially at FN concentration of 5 micrograms/ml. In addition, FN-pentapeptide has shown the ability to bind to HIV-1 infected cells. On the other hand, preincubation with antibodies against FN abolished the binding of FN to HIV-1 infected cells. Finally, FN has shown to bind to HIV-1 glycoproteins, including gp41 and gp120. In contrast, no binding to HIV-1 core proteins, including p15 and p24, was noted. We suggest that FN, in binding HIV-1 particles, may reduce viremia and thus may be involved in the clearance of viral proteins from the cells.

Abstract
AIMS To evaluate the fibronectin concentrations in the cerebrospinal fluid of HIV-1 infected patients with central nervous system disorders. METHODS Fibronectin was determined by an immunoturbidimetric assay in 41 HIV-1 infected patients with AIDS dementia complex, progressive multifocal leucoencephalopathy, and opportunistic infections. RESULTS A significant decrease in fibronectin concentrations in the cerebrospinal fluid of patients with AIDS and dementia complex and progressive multifocal leucoencephalopathy was observed, as well as in those with opportunistic infections of the central nervous system (p < 0.0001). In particular, a significant decrease in fibronectin concentration in cerebrospinal fluid was observed in patients with cerebral toxoplasmosis and cryptococcal meningitis (p < 0.0001). CONCLUSIONS Because fibronectin can bind to several viruses, fungi, and protozoa, it is conceivable to suppose that the consumption of fibronectin in the cerebrospinal fluid of patients with neurological disorders may be related to the binding of fibronectin to HIV itself, or to viral proteins, or to organisms responsible for opportunistic infections.

Abstract
OBJECTIVE To determine serum levels of acute-phase proteins and interleukin 1B, interleukin 6, tumor necrosis factor alpha, and interleukin 8 in children with pertussis. DESIGN Cross-sectional study. SETTING Divisions of Infectious Diseases, Regional Hospital, and Pediatrics, University of Pavia, Varese, Italy. PARTICIPANTS Eight children with pertussis, six with acute febrile infections, and eight healthy control children matched for sex, age, and time presentation over a 32-month study period. INTERVENTIONS None. MEASUREMENTS/MAIN RESULTS An immunoenzymatic assay was used to detect serum levels of all cytokines. Normal values of C-reactive protein, alpha 1-acid glycoprotein, and erythrocyte sedimentation rate were observed in the serum of patients with pertussis. The mean (+/- SD) detectable levels of tumor necrosis factor alpha (65.0 +/- 50.4 pg/mL) and interleukin 6 (32.3 +/- 17.8 pg/mL) were observed in the serum of patients with pertussis. In contrast, a nonsignificant increment of interleukin 1B levels (66.5 +/- 83.7 pg/mL) and interleukin 8 levels (12.7 +/- 17.8 pg/mL) was noted in the serum of the same patients. Increased and significant levels of all four cytokines were noted in most of the serum samples of patients with acute febrile infections. CONCLUSIONS Acute-phase response is absent in patients with pertussis, whereas detectable and significant serum levels of tumor necrosis factor alpha and interleukin 6 were observed in some such patients.

Abstract
We investigated the role of lymphocyte function-associated antigen 1 (LFA-1) in human T cell polarization and migration assay by using monoclonal antibody specific to beta chain (CD18) and alpha chain (CD11a). T cell polarization in response to fetal calf serum (FCS) and colchicine was suppressed by the addition of CD18 and CD11a antibodies. Furthermore, T cell migration in response to lymphocyte chemotactic factor (LCF) and casein was markedly depressed by the addition of CD18 and CD11a antibodies. Additional studies to evaluate effects of interleukin 8 (IL-8) on polarization and migration of T cells preincubated with CD18 or CD11a antibody showed that IL-8 restored the capability of migration of T cells, whereas did not restore polarization activity of such cells. These studies indicate that LFA-1 plays a role in the polarization and migration of T cells and that IL-8 may positively interfer with LFA-1-adhesion molecules.

Abstract
To prevent delayed cardiomyopathy induced by adriamycin and subsequent severe congestive heart failure, a monitoring schedule with noninvasive techniques to measure cardiac performance (CPK-MB, electrocardiographic, systolic time intervals, echocardiography and quantitative radionuclide angiography) has been used. 15 patients, 33 to 65 years old, with metastatic breast carcinoma, previously treated with a polychemotherapy protocol not including adriamycin have been studied. Monitoring at 0 time allowed to exclude one patient with previous asymptomatic cardiomyopathy and to treat patients at risk with cardiovascular pathology, up to reach and even exceed the dosage of 550 mg/m2. Four of the treated patients showed positive findings of cardiomyopathy at different adriamycin dosage levels: 2 asymptomatic dilatative cardiomyopathies, 1 symptomatic and 1 with congestive heart failure remitted with medical therapy. No patient died because of cardiovascular complications. The results obtained show that of all noninvasive techniques used, only quantitative radionuclide angiocardiography allowed, when employed following an adequate monitoring schedule, to detect reliable findings of moderate and reversible cardiomyopathy thus indicating the appropriate time for drug discontinuation.

Abstract
The pharmacokinetics of propafenone and 5-OH-propafenone and their relationship with the antiarrhythmic action and side effects have been studied in 10 patients with stable, frequent, premature ventricular beats (224-928 premature ventricular complexes/h). Observations were made after a single dose of propafenone 300 mg p.o., and after 1 and 3 months (only 5 out of 10 patients) of therapy with 300 mg t.d.s. After 1 month of treatment the plasma elimination half-life of propafenone (6.7 h) was almost twice as long as after a single dose (3.5 h), and the area under the plasma propafenone concentration-time curve (7620 ng.ml-1.h) was significantly larger than after single dose (3522 ng.ml-1.h); this was also true for the metabolite. The ratio of the AUCs of 5-OH-propafenone and propafenone decreased from the single dose (0.63) to 1 month (0.32). These variables remained stable up to 3 months. Eight patients had greater than or equal to 75% reduction of premature ventricular complexes after 3 days of therapy, and in 7 they were completely suppressed; the response was maintained over 1 to 3 months. Side effects were minor and in no case had the drug to be withdrawn or the dose reduced. Thus, the kinetics of propafenone were time-dependent. Its active metabolite did not accumulate greatly during chronic treatment. The lasting antiarrhythmic effect observed in some patients suggests a b.d.s. regimen instead of t.d.s. dosing in selected patients.
