RESUMO

BACKGROUND: Surgical management of large ventral hernias (VH) has remained a challenge. Various techniques like anterior component separation and posterior component separation (PCS) with transversus abdominis release (TAR) have been employed. Despite the initial success, the long-term efficacy of TAR is not yet comprehensively studied. Authors aimed to investigate the early-, medium-, and long-term outcomes and health-related quality of life (QoL) in patients treated with PCS and TAR. METHODS: This multicenter retrospective study analyzed data of 308 patients who underwent open PCS with TAR for primary or recurrent complex abdominal hernias between 2015 and 2020. The primary endpoint was the rate of hernia recurrence (HR) and mesh bulging (MB) at 3, 6, 12, 24, and 36 months. Secondary outcomes included surgical site events and QoL, assessed using EuraHS-QoL score. RESULTS: The average follow-up was 38.3 ± 12.7 months. The overall HR rate was 3.5% and the MB rate was 4.7%. Most of the recurrences were detected by clinical and ultrasound examination. QoL metrics showed improvement post-surgery. CONCLUSIONS: This study supports the long-term efficacy of PCS with TAR in the treatment of large and complex VH, with a low recurrence rate and an improvement in QoL. Further research is needed for a more in-depth understanding of these outcomes and the factors affecting them.

RESUMO

Antiretroviral therapy (ART) significantly reduced Human Immunodeficiency Virus (HIV) morbidity and mortality; nevertheless, stigma still characterises the living with this condition. This study explored patients' coping experience by integrating narrative medicine (NM) in a non-interventional clinical trial. From June 2018 to September 2020 the study involved 18 centres across Italy; enrolled patients were both D/C/F/TAF naïve and previously ART-treated. Narratives were collected at enrolment (V1) and last visit (V4) and then independently analysed by three NM specialist researchers through content analysis. One-hundred and fourteen patients completed both V1 and V4 narratives. Supportive relationships with clinicians and undetectable viral load facilitated coping. Conversely, lack of disclosure of HIV-positive status, HIV metaphors, and unwillingness to narrate the life before the diagnosis indicated internalised stigma. This is the first non-interventional study to include narratives as patient reported outcomes (PROs). Improving HIV awareness and reducing the sense of guilt experienced by patients helps to overcome stigma and foster coping.

RESUMO

OBJECTIVE: This article deals with the attempt to join HIV and geriatric care management in the 2017 edition of the Italian guidelines for the use of antiretrovirals and the diagnostic-clinical management of HIV-1 infected persons. METHODS: The outlined recommendations are based on evidence from randomized clinical trials and observational studies published in peer-reviewed journals and/or presented at international scientific conferences in recent years. The principles of starting antiretroviral therapy in elderly patients and the viro-immunological goals are the same as in the general HIV population. However, there are some specificities to consider, related to the host as well as the therapy itself. HIV care in elderly patients must shift from a combined AntiRetroviral Therapy specific approach to a more comprehensive management, and from a disease-based model (list of co-morbidities) to a multi-morbidity and frailty standpoint. The implementation of a geriatric approach, based on the Comprehensive Geriatric Assessment, is essential and consists of a broader evaluation of health status. This multidimensional and multidisciplinary evaluation is focused on the development of a tailored intervention plan. Polypharmacy is a frequent condition in the older population and an independent risk factor for negative health-related outcomes. This can be overcome with a multidisciplinary and cooperative approach involving HIV specialists, geriatricians and primary care physicians. CONCLUSION: The inclusion of geriatric care becomes necessary due to the novel needs of an evolving patient population. It is important to underline that the HIV specialist will continue to lead multidimensional interventions and optimize quality of care for HIV-positive people.

RESUMO

OBJECTIVES: To analyse the variation of hepatitis C virus (HCV) prevalence and genotype distribution and their determinants in people living with human immunodeficiency virus (HIV) who entered care between 1997 and 2015. METHODS: HIV-infected patients enrolled in ICONA who were tested for HCV antibodies (HCV-Ab) were included. RESULTS: Overall 3407 of 12 135 (28.1%) were HCV-Ab+; and 735 of 12 135 (6.1%) were HBsAg+. Among patients whose HCV genotype was known, the most represented were genotypes 1 and 3. The prevalence of HCV infection decreased from 49.2% (2565/5217) during 1997-2002 to 10.2% (556/5466) during 2009-2015. The frequency of genotype 1a increased from 29.0% (264/911) to 43.0% (129/300), whereas genotype 3 decreased from 38.5% (351/911) to 27.0% (81/300). Independent predictors of HCV-Ab+ status were being female (adjusted OR (AOR) 1.23, 95% CI 1.04-1.50, p = 0.01), risk category (versus injecting drug users: men who have sex with men AOR 0.01, 95% CI 0.01-0.01, p <0.001; heterosexuals AOR 0.01, 95% CI 0.01-0.01, p <0.001; other/unknown AOR 0.02, 95% CI 0.01-0.02, p <0.001), being cared for in Central Italy (versus being cared for in Northern Italy: AOR 0.85, 95% CI 0.73-0.98, p <0.001), being Italian-born (AOR 1.44, 95% CI 1.16-1.80, p = 0.001) and being enrolled in less recent calendar years (versus 1997-2002: 2009-2015 AOR 0.23, 95% CI 0.19-0.27, p <0.001; 2003-2008 AOR 0.49, 95% CI 0.41-0.61, p <0.001). CONCLUSIONS: The prevalence of HCV infection in HIV-infected patients entering into care in Italy significantly declined in more recent calendar years. After adjusting for risk factors and calendar years, HCV co-infection was more frequent in females and in those born in Italy.

RESUMO

SETTING: Blood interferon-γ inducible protein 10 (IP-10) has been proposed as a biomarker of disease activity for both tuberculosis (TB) and human immunodeficiency virus (HIV) infection. Urine IP-10 has been detected in adults with active TB, and its level decreases after successful anti-tuberculosis treatment. OBJECTIVE: To evaluate blood and urine IP-10 as biomarker of disease activity. DESIGN: Patients with HIV-TB and active TB were enrolled. Individuals with HIV infection only and healthy donors were included as controls. Blood and urine IP-10 levels were measured using an enzyme-linked immunosorbent assay. RESULTS: Of 39 active TB patients enrolled, 24 were HIV-infected and 15 were HIV-uninfected. Of 87 control subjects without active TB, 54 were HIV-infected and 33 were HIV-uninfected. IP-10 analysis was performed in patients with concomitant blood and urine sample collection. Blood IP-10 was associated with active TB, regardless of HIV infection status; urine IP-10 levels were increased in active TB patients, although the difference was significant in HIV-infected individuals only. Finally, in HIV-infected patients, both blood and urine IP-10 levels were inversely correlated with CD4 T-cell counts. CONCLUSION: These findings suggest that IP-10 could be used as a biomarker for disease activity (inflammation).

RESUMO

Depression in HIV/AIDS patients affects adherence and disease progression and often goes unnoticed. DHIVA is a cross-sectional epidemiologic survey, investigating the prevalence of depression in people living with HIV through use of a validated self-administered scale (CES-D-20), as well and the degree of concordance between the physician's perception and patients' reports. A total of 690 HIV-infected patients attending 24 centers across Italy were enrolled. Concordance was calculated by K statistics. Association between depression and subject characteristics were evaluated through univariate and multivariate logistic models (OR and 95%CI). The prevalence of depressive symptoms was 48.8% from patient's questionnaires and 49.5% from physicians' reports, with a low/fair concordance (K = .38, p < .001). CES-D-20 found severe depression in 22.5% of the patients vs 4% identified by physicians. 135/155 (87%) of the severely depressed patients (according to CES-D-20) were considered as non or mildly/moderately depressed by physicians. Risk of severe depression was associated with unemployment (p < .001), previous depression (p < .001), treatment failure (p = .001), and former smoking status (p = .018). Depression is frequent in HIV-infected patients in the HAART era, with significant discrepancy between physician perception and the self-reported CES-D-20 results. Screening should be mandatory in all HIV patients.

RESUMO

The human equilibrative nucleoside transporter 1 (hENT1) is the major means by which gemcitabine enters human cells; recent evidence exists that hENT1 is expressed in carcinoma of the ampulla of Vater and that it should be considered as a molecular prognostic marker for patients with resected ampullary cancer. Aim of the present study is to evaluate the variations of hENT1 expression in ampullary carcinomas and to correlate such variations with histological subtypes and clinicopathological parameters. Forty-one ampullary carcinomas were histologically classified into intestinal, pancreaticobiliary and unusual types. hENT1 and Ki67 expression were evaluated by immunohistochemistry, and apoptotic cells were identified by the terminal deoxynucleotidyl transferase mediated deoxyuridine triphosphate biotin nick end labelling (TUNEL) method. hENT1 overexpression was detected in 63.4% ampullary carcinomas. A significant difference in terms of hENT1 and Ki67 expression was found between intestinal vs. pancreaticobiliary types (P=0.03 and P=0.009 respectively). Moreover, a significant statistical positive correlation was found between apoptotic and proliferative Index (P=0.036), while no significant correlation was found between hENT1 and apoptosis. Our results on hENT1 expression suggest that classification of ampullary carcinoma by morphological subtypes may represent an additional tool in prospective clinical trials aimed at examining treatment efficacy; in addition, data obtained from Ki67 and TUNEL suggest a key role of hENT1 in tumour growth of ampullary carcinoma.

RESUMO

The incidence of and predictors of acquired immunodeficiency syndrome-defining malignancies (ADMs) and non-ADM (NADMs) were evaluated in a large Italian cohort. The incidence of ADM and NADM was 5.0 cases per 1000 person-years of follow-up (95% confidence interval, 4.3-5.8 cases per 1000 person-years of follow-up) and 2.4 cases per 1000 person-years of follow-up (95% confidence interval, 1.9-3.1 cases per 1000 person-years of follow-up), respectively. Lower current CD4 cell count was an independent predictor of developing malignancies, with the association being stronger for ADM than for NADM.

RESUMO

BACKGROUND: Individuals with advanced HIV infection naïve to antiretroviral therapy represent a special population of patients frequently encountered in clinical practice. They are at high risk of disease progression and death, and their viroimmunologic response following the initiation of highly active antiretroviral therapy may be more incomplete or slower than that of other patients. Infection management in such patients can also be complicated by underlying conditions, comorbidities, and the need for concomitant medications. AIM: To provide practical guidelines to those clinicians providing care to HIV-infected patients in terms of diagnostic assessment, monitoring, and treatment. CONCLUSIONS: The principals of antiretroviral treatment in asymptomatic naïve patients with advanced HIV infection are the same as those applicable to the general population with asymptomatic HIV infection. Naïve patients with advanced HIV infection and a history of AIDS-defining illnesses urgently need antiretroviral treatment, with the choice of antiretroviral regimen and timetable based on such factors as concomitant treatment and prophylaxis, drug interactions, and potential concomitant drug toxicity. Finally, an adequate counseling program - both before and after HIV-testing - that includes aspects other than treatment adherence monitoring is a crucial step in disease management.

RESUMO

In 1998 Tazawa and Tsutsumi described for the first time a case of Helicobacter pylori (HP)-related gastritis characterized by the presence of a conspicuous plasma cell infiltrate with Russell bodies, and coined the term Russell body gastritis (RBG). A 59-year-old HIV-positive man complaining of recurrent epigastric pain underwent an upper gastrointestinal endoscopy revealing in the stomach only hyperemia in the antral portion. Histology showed a moderate glandular atrophy associated with an expansion of the lamina propria due to an infiltration of monomorphous cells with eosinophilic cytoplasm inclusions and eccentric nuclei, somewhat resembling plasma cells. A diagnosis of HP-related RBG was made, after excluding, by means of histochemical, immunohistochemical stainings and molecular studies, a neoplastic process. A review of all cases of RBG previously described in the English literature is reported in order to examine the clinical, endoscopic and microscopic features of this histopathological entity and the possible pathogenetic mechanisms.

RESUMO

BACKGROUND: Promyelocytic leukemia (PML) tumor suppressor gene plays a key role in acute PML pathogenesis but its involvement in pathogenesis and prognosis of solid cancers has not been defined yet. PATIENTS AND METHODS: In all, 62 ampullary adenocarcinoma patients who underwent curative surgery between 1996 and 2005 were included. Expression analysis of PML was carried out by immunohistochemical staining and correlated with disease-free survival (DFS) and overall survival (OS). RESULTS: In 24 tumor specimens (38.7%), PML was classified as absent, in 16 (25.8%) as focally expressed and in 22 (35.5%) as diffusely expressed. By univariate analysis, DFS was significantly influenced by pathological T stage (P=0.03), lymph nodal involvement (P=0.002), and PML expression (P=0.001). DFS in patients without PML expression was 28.0 months versus 45.1 and 75.5 for patients with focal and diffuse expression, respectively. OS in the group of patients without PML expression, with focal expression, and with diffuse expression was 40, 48, and 77 months, respectively (P=0.002). By a multivariate analysis, PML expression was the strongest prognostic factor for DFS (P=0.003) and the only statically significant prognostic factor for OS (P=0.009). CONCLUSIONS: Our preliminary data suggest PML as a novel prognostic tool for ampullary cancer patients.

RESUMO

BACKGROUND: Gemcitabine is an acceptable alternative to best supportive care in the treatment of advanced biliary tract cancers. The human equilibrative nucleoside transporter 1 (hENT1) is a ubiquitous protein and is the major means by which gemcitabine enters human cells. Moreover, recent reports indicate a significant correlation between immunohistochemical variations of hENT1 in tumor samples and survival after gemcitabine therapy in patients with solid tumors. MATERIALS AND METHODS: We used immunohistochemistry to assess the abundance and distribution of hENT1 in tumor samples from radically resected cancer of the ampulla, and sought correlations between immunohistochemical results and clinical parameters including disease outcomes. RESULTS: In the 41 individual tumors studied, 12 (29.3%) had uniformly high hENT1 immunostaining. Statistical analysis showed a significant correlation between hENT1 and Ki-67 (P = 0.04). No statistical significant differences were found between immunohistochemical findings and patient characteristics (sex, age, and tumor-node-metastasis). On univariate analysis, hENT1 and Ki-67 expression were associated with overall survival (OS). Specifically, those patients with overexpression of hENT1 showed a shorter OS (P = 0.022) and those with high Ki-67 staining showed a shorter survival (P = 0.05). CONCLUSIONS: hENT1 expression is a molecular prognostic marker for patients with resected ampullary cancer and holds promise as a predictive factor to assist in chemotherapy decisions.

RESUMO

A case report of dual sexual transmission, with secondary transmission from naïve to naïve patient, of HIV harbouring K103N and L100I mutations, conferring full non-nucleoside reverse transcriptase inhibitor (NNRTI) resistance, plus 2 nucleoside analogous reverse transcriptase inhibitor (NRTI) mutations is described. The secondary transmission of the resistant virus was confirmed by phylogenetic analysis. Data also suggest that mutations related to NRTI and NNRTI resistance may persist for a long time in naive patients, over 2 years in the present case report.

RESUMO

A 25-year-old Caucasian woman with a medical history of acute promyelocytic leukemia presented to the emergency department with massive gastrointestinal bleeding. A bone marrow biopsy excluded hemorrhagic leukemia. Esophagogastroduodenoscopy, colonoscopy, emergency abdominal angiography, abdominal CT scan, and wireless capsule endoscopy were performed but no source of bleeding could be detected. Tc-99m RBC scintigraphy was consistent with a small bowel bleeding focus. The persistent and focal images in the right abdomen were suggestive of Tc-99m RBC trapping in the lumen of a Meckel diverticulum (MD). In accordance with this suspicion, successive Tc-99m pertechnetate scintigraphy was performed after 3 days, consistent with the diagnostic hypothesis. Due to the persisting severe bleeding (with a drop in baseline hemoglobin from 10.4 to 7.1 g/dL), despite 8 units of blood transfusion, emergency surgery was performed. Through a minilaparotomy a segmental small bowel resection, including Meckel diverticulum, was performed. The postoperative course was uneventful.

RESUMO

The present document contains recommendations for assessment, prevention and treatment of cardiovascular risk for HIV-infected patients. All recommendations were graded according to the strength and quality of the evidence and were voted on by 73 members of the Italian Cardiovascular Risk Guidelines Working Group which includes both experts in HIV/AIDS care and in cardiovascular and metabolic medicine. Since antiretroviral drug exposure represents only one risk factor, continued emphasis on an integrated management is given. This should include prevention and treatment of known cardiovascular risk factors (such as dyslipidaemia, diabetes, insulin resistance, healthy diet, physical activity, avoidance of smoking), but also rational switch of antiretroviral drugs. A rational switch strategy should consider both metabolic and anthropometric disturbances and effectiveness of antiretroviral regimens.

RESUMO

BACKGROUND: There is evidence that the anti-neoplastic effect of non-steroidal anti-inflammatory drugs is attributable to cyclooxygenase-2 (COX-2) inhibition, but the exact mechanisms whereby COX-2 can promote tumour cell growth remain unclear. One hypothesis is the stimulation of tumour angiogenesis by the products of COX-2 activity. To data, there have been few clinicopathological studies on COX-2 expression in human ampullary carcinoma and no data have been reported about its relation with tumour angiogenesis. OBJECTIVE: To investigate by immunohistochemistry the expression of COX-2 and the angiogenesis process in a series of primary untreated ampullary carcinomas. METHODS: Tissue samples from 40 archival ampullary carcinomas were analysed for COX-2, vascular endothelial growth factor (VEGF), and an endothelial cell marker von Willebrand factor (vWF) by immunohistochemistry, using specific antibodies. RESULTS: COX-2 expression was detected in 39 tissue samples (97.5%), of which two (5%) were graded as weak, 26 (65%) as moderate, and 11 (27.5%) as strong. Only one lesion (2.5%) was negative for COX-2 expression. VEGF expression was detected in 36 tissue samples (90%). A significant positive correlation was found between COX-2 and VEGF expression. No statistic correlation was found between COX-2 expression and microvessel density. CONCLUSIONS: COX-2 is highly expressed in ampullary carcinomas. This suggests an involvement of the COX-2 pathway in ampullary tumour associated angiogenesis, providing a rationale for targeting COX-2 in the treatment of ampullary cancer.

RESUMO

Pancreatic cancer is one of the most aggressive gastrointestinal cancer with less than 10% long-term survivors. The apoptotic pathway deregulation is a postulated mechanism of carcinogenesis of this tumour. The present study investigated the prognostic role of apoptosis and apoptosis-involved proteins in a series of surgically resected pancreatic cancer patients. All patients affected by pancreatic adenocarcinoma and treated with surgical resection from 1988 to 2003 were considered for the study. Patients' clinical data and pathological tumour features were recorded. Survivin and Cox-2 expression were evaluated by immunohistochemical staining. Apoptotic cells were identified using the TUNEL method. Tumour specimen of 67 resected patients was included in the study. By univariate analysis, survival was influenced by Survivin overexpression. The nuclear Survivin overexpression was associated with better prognosis (P = 0.0009), while its cytoplasmic overexpression resulted a negative prognostic factor (P = 0.0127). Also, the apoptotic index was a statistically significant prognostic factor in a univariate model (P = 0.0142). By a multivariate Cox regression analysis, both the nuclear (P = 0.002) and cytoplasmic (P = 0.040) Survivin overexpression maintained the prognostic statistical value. This is the first study reporting a statistical significant prognostic relevance of nuclear and cytoplasmic Survivin overexpression in pancreatic cancer. In particular, patients with high nuclear Survivin staining showed a longer survival, whereas patients with high cytoplasmic Survivin staining had a shorter overall survival.

RESUMO

JC virus (JCV) causes progressive multifocal leukoencephalopathy (PML), characterized by multiple areas of demyelination and attendant loss of brain function. PML is often associated with immunodepression and it is significantly frequent in AIDS patients. The viral genome is divided into early and late genes, between which lies a non-coding control region (NCCR) that regulates JCV replication and presents a great genetic variability. The NCCR of JCV archetype (CY strain) is divided into six regions: A-F containing binding sites for cell factors involved in viral transcription. Deletions and enhancements of these binding sites characterize JCV variants, which could promote viral gene expression and could be more suitable for the onset or development of PML. Therefore, we evaluated by means of polymerase chain reaction (PCR) the presence of JCV genome in cerebrospinal fluid (CSF) of HIV positive and negative subjects both with PML and after sequencing, we analyzed the viral variants found focusing on Sp1 binding sites (box B and D) and up-TAR sequence (box C). It is known that Sp1 activates JCV early promoter and can contribute in maintaining methylation-free CpG islands in active genes, while up-TAR sequence is important for HIV-1 Tat stimulation of JCV late promoter. Our results showed that in HIV-positive subjects all NCCR structures presented enhancements of up-TAR element, whereas in HIV-negative subjects both Sp1 binding sites were always retained. Therefore, we can support the synergism HIV-1/JCV in CNS and we can hypothesize that both Sp1 binding sites could be important to complete JCV replication cycle in absence of HIV-coinfection.
