Prognostic role of inflammatory biomarkers in HIV-infected patients with a first diagnosis of hepatocellular carcinoma: A single-center study.

OBJECTIVES: To assess hepatocellular carcinoma (HCC) survival and to investigate the prognostic role of immunonutritional biomarkers, as neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR) and prognostic nutritional index (PNI), in a cohort of human immunodeficiency virus (HIV)-infected patients. METHODS: All HIV-positive patients diagnosed with HCC at our Department from January 2000 to December 2013 were included. The outcomes were overall survival (OS), recurrence-free survival (RFS), and liver-related death (LRD). To examine the role of inflammatory biomarkers on the outcomes, univariate and multivariable Cox regression models were used. Receiver operating characteristic (ROC) curves were implemented to evaluate the prediction role of NLR, PLR, and PNI. RESULTS: A total of 40 patients (90% males) with a mean age of 48.3 years (SD = 5.6) were recruited. NLR ≥ 2.9 was associated with all causes mortality, as well as, PLR ≥ 126. NLR and PLR were predictors of OS, RFS, and LRD, while PNI did not emerge as a prognostic marker. According to the multivariate analysis, no HCC treatment was the only risk factor associated with risk of death. The areas under the ROC curves were 68.3 (95% confidence interval [CI], 54.5-82.1) for PLR and 66.3 (95% CI, 54.3-78.2) for NLR at 3 years; similar results were found at 5 years of follow-up. CONCLUSIONS: Although, if examined singularly, NLR and PLR are prognostic factors for HCC recurrence and survival in HIV-infected patients, at the multivariate analysis, "no HCC treatment" remains the only independent risk factor associated with fatal outcome.

A COPD Case-Finding Program in a Large Cohort of HIV-Infected Persons.

BACKGROUND: COPD screening guidelines in patients with HIV are lacking, and data about its under-diagnosis are still limited. This study aimed to determinate the feasibility of a case-finding program and the prevalence of COPD under-diagnosis in a large cohort of HIV-infected subjects. METHODS: All out-patients attending their routine visit for HIV monitoring at Spedali Civili General Hospital in Brescia, Italy, from February 2015 to January 2016, were enrolled. The case-finding program was structured in three steps: questionnaire administration, pre-bronchodilator spirometry testing measured with a portable spirometer, and post-bronchodilator diagnostic spirometry during a pulmonology appointment. RESULTS: A total of 1,463 subjects were included; the average age was 46.2 ± 10.3 y. Two hundred eighty-two subjects had a positive questionnaire; 190 completed portable spirometry, and approximately 34% (65 of 190 subjects) reported respiratory impairment; of these 65 subjects, 33 completed diagnostic spirometry, and 66.7% (22 of 33) showed evidence of COPD, including 2 subjects with severe airway obstruction (GOLD stage 3, according to the Global Initiative for Chronic Obstructive Lung Disease). High dropout rates were observed in our program. Individuals with COPD exacerbations showed lower CD4+ cell counts at screening compared to those without acute worsening of symptoms (534 cells/mm3 for subjects with GOLD 1 exacerbations and 495 cells/mm3 for subjects with GOLD 2 exacerbations vs 781 cells/mm3 for those without acute worsening of symptoms). The positive predictive value of the COPD screening questionnaire and portable spirometry was 33.8%. CONCLUSIONS: COPD may be under-diagnosed in HIV-infected people, and case-finding programs are an urgent issue to address as part of routine practice in these individuals.

Comparison between the gold standard DXA with calcaneal quantitative ultrasound based-strategy (QUS) to detect osteoporosis in an HIV infected cohort

ABSTRACT Introduction: Osteoporosis represents one of the most frequent comorbidity among HIV patients. The current standard method for osteoporosis diagnosis is dual-energy X-ray absorptiometry. Calcaneal quantitative ultrasound can provide information about bone quality. The aims of this study are to compare these two methods and to evaluate their ability to screen for vertebral fracture. Methods: This cross-sectional study was conducted in HIV patients attending the Clinic of Infectious and Tropical Diseases of Brescia during 2014 and who underwent lumbar/femoral dual-energy X-ray absorptiometry, vertebral fracture assessment and calcaneal quantitative ultrasound. The assessment of osteoporosis diagnostic accuracy was performed for calcaneal quantitative ultrasound and for vertebral fracture comparing them with dual-energy X-ray absorptiometry. Results: We enrolled 73 patients and almost 48% of them had osteoporosis with at least one of the method used. Vertebral fracture were present in 27.4%. Among patients with normal bone measurements, we found vertebral fracture in proportion between 10% and 30%. If we used calcaneal quantitative ultrasound method and/or X-ray as screening, the percentages of possible savable dual-energy X-ray absorptiometry ranged from 12% to 89% and misclassification rates ranged from 0 to 24.6%. A combined strategy, calcaneal quantitative ultrasound and X-Ray, identified 67% of patients with low risk of osteoporosis, but 16.4% of patients were misclassified. Conclusions: We observed that patients with osteoporosis determined by calcaneal quantitative ultrasound and/or dual-energy X-ray absorptiometry have higher probability to undergo vertebral fracture, but neither of them can be used for predicting vertebral fracture. Use of calcaneal quantitative ultrasound for screening is a reasonable alternative of dual-energy X-ray absorptiometry since our study confirm that none strategy is clearly superior, but both screen tools must be always completed with X-ray.

Factors that contribute to hypertransaminasemia in patients with celiac disease or functional gastrointestinal syndromes.

BACKGROUND & AIMS: Transaminasemia develops via different pathways in patients with celiac disease; no information is available on risk factors specifically attributable to celiac disease. METHODS: We analyzed data collected from consecutive patients referred from January 1997 through December 2009 to the celiac disease clinic at the Spedali Civili of Brescia, Italy. We assessed the factors affecting hypertransaminasemia in 683 patients with celiac disease (based on serologic and biopsy analysis, cohort A; 34 ± 14 years of age) and 304 with functional syndromes (cohort B; 37 ± 13 years of age). RESULTS: Hypertransaminasemia was detected in 138 patients in cohort A (20%). It was associated with malabsorption (odds ratio [OR], 2.22; P = .004), diarrhea (OR, 1.72; P = .005), and increasing severity of mucosal lesion (Marsh-Oberhuber class; OR, 1.46; P = .001) but not with body mass index (BMI) or the serum level of tissue-transglutaminase antibodies (tTG). Hypertransaminasemia was detected in 22 patients in cohort B (7%) and was associated with the World Health Organization's BMI categories (OR, 7.9; P < .001). In subsets of patients studied with the same analytical method (313 of cohort A and 188 of cohort B), the level of tTG was significantly higher in cohort A at baseline (25.2 ± 16.9 U/L aspartate aminotransferase [AST]) than in cohort B (20.6 ± 9.9 U/L AST, P < .0001) and was related to BMI in cohort B (P = .0012) but not cohort A. When patients were placed on gluten-free diets, the levels of AST decreased from 25.2 ± 16.9 U/L to 19.9 ± 6.6 U/L (P < .0001), independently of the changes of duodenal histology and tTG and correlated with BMI (P = .0007); the prevalence of hypertransaminasemia decreased from 13% to 4%. CONCLUSIONS: Patients with celiac disease have a higher prevalence of hypertransaminasemia than controls (patients with functional syndromes). Hypertransaminasemia is related to the severity of the duodenal lesion and malabsorption but not BMI. By contrast, there was a positive correlation between the levels of AST and BMI in controls; this relationship was restored when patients with celiac disease were placed on gluten-free diets.

[A population-based database to study malignancies in HIV-infected patients in the Local Health Unit of Brescia (Northern Italy), period 1999-2009]. / Creazione di un database integrato per lo studio dei tumori maligni nei pazienti con infezione da HIV nell'ASL di Brescia nel periodo 1999-2009.

OBJECTIVE: to complete the database of all patients infected by the human immunodeficiency virus (HIV) who lives in the area belonging to the Local Health Unit (ASL) of Brescia, Northern Italy,with all the cancers diagnosed in the period 1999-2009. DESIGN: diagnoses of cancer between 1999 and 2009 registered in the electronic database in use in the Clinic of Infectious and Tropical Diseases (source A) for the clinic follow-up of HIV-infected patients were checked. Then, the cases were integrated with the data recorded in the ASL database (source B) and in the Cancer Registry of Brescia (source C). SETTING AND PARTICIPANTS: all HIV-infected patients belonging to the ASL of Brescia followed-up in the Clinic of Infectious and Tropical Diseases of Brescia. MAIN OUTCOME MEASURES: in the database were included all HIV-positive patients who had a diagnosis of cancer between 1999 and 2009. The diagnosis of cancer had to be present at least in two of the three sources considered; if it was recorded only in one of them, the source had to be an histological document or confirmed directly by the patient him/herself. RESULTS: from the sourceA, 339 diagnoses of cancer were recorded, then other 82 records from the sources B and C were added, achieving a total of 421 cancers, belonging to 391 different patients. Half of the diagnoses was present in all the three sources considered. Among the AIDS-defining cancers (No. 200; 47.5%), Kaposi's sarcoma and non-Hodgkin lymphoma were the most frequent diagnosed tumours (22.8% and 22.33%, respectively). Among the non-AIDS-defining cancers (No. 221; 52.5%), malignancies of the skin other than melanoma (No. 41; 9.74%), tumours of the liver (No. 34; 8.08%) and Hodgkin lymphoma (No. 31; 7.36%) were the most frequent tumours. CONCLUSIONS: the database of all HIVpositive patients, including the diagnoses of cancer between 1999 and 2009, represents an important instrument, not only for the clinical practice: collecting clinical and sociodemographics characteristics of these patients, it would be possible to perform clinical and epidemiological studies.

Burden of non-AIDS-defining and non-virus-related cancers among HIV-infected patients in the combined antiretroviral therapy era.

The risk of cancer is substantially increased in HIV-infected patients. However, little is known about non-AIDS-defining cancers (NADCs) without an infectious etiology. A total of 5,090 HIV-infected patients registered in the Local Health Authority (LHA) of Brescia and receiving primary care at our clinic were included in a retrospective (1999-2009) analysis. The cancer diagnoses were obtained through a record-linkage procedure between our database and the LHA general database and population-based Cancer Registry of LHA. We compared risks of these malignancies with those of the general population living in the same health area by using age-standardized incidence ratios (SIRs). Poisson regression analysis was used to assess factors associated with non-virus-related NADCs. We recorded an increase in the SIR of non-virus-related NADCs over time, with 138 cancers diagnosed in 131 patients. The mean incidence rate was 42.6/10,000 person years and the median age at the diagnosis was 49 (range, 28-78) years old. Stratifying for gender, only HIV-infected males had an increased risk of non-virus-related NADCs [SIR=1.86; 95% confidence interval (CI), 1.55-2.26]. Risk was higher for lung (SIR=3.59; 95% CI, 2.36-5.45) and testis cancer (SIR=3.11; 95% CI, 1.48-6.52). However,, cancers of the prostate and breast in HIV-positive men and women were null (SIR=1.10; 95% CI, 0.53-2.32 and SIR=0.91; 95% CI, 0.47-1.74, respectively). The only predictors of non-virus-related NADCs included older age [incidence rate ratio (IRR)=1.10; 95% CI, 1.08-1.12 per each additional year, p<0.001] and a shorter or no exposition to combined antiretroviral therapy (cART) (IRR=2.31; 95% CI, 1.38-3.89, p=0.002). A CD4⁺ count lower than 50/mm³ was significantly associated with cancers only in the univariate model (IRR=1.40; 95% CI, 0.99-1.98, p=0.057). HIV-infected men showed a 2-fold increased risk of non-virus-related NADCs compared to the general population. However, the use of cART appeared to be beneficial in protecting against the development of these malignancies.

Clinical characteristics, incidence, and risk factors of HIV-related Hodgkin lymphoma in the era of combination antiretroviral therapy.

HIV-infected patients are at increased risk for developing HIV-related Hodgkin lymphoma (HIV-HL) despite the success of combination antiretroviral therapy (cART). To study the incidence of HIV-HL in HIV-patients with respect to the general population of Brescia, Italy, we conducted a single-center cohort study of HIV-patients followed from 1999 to 2009. The incidence of HIV-HL was compared to the incidence in the general population of Brescia using standardized incidence ratios (SIRs). Poisson analysis was used to study the association between covariates and HL. A total of 5085 HIV-patients were observed among 30,946 person-years; 30 patients developed HIV-HL. The incidence rate was 9.9 (95% confidence interval [CI], 6.7-14.1) per 10,000 person-years of follow-up. HL was substantially more frequent in HIV-patients than in the general population living in the same district area [standardized incidence rate, SIR=21.8 (95% CI, 15.33-31)]. The risk of HIV-HL tended to increase with lowering CD4+ cell counts at time of HL diagnosis [adjusted incidence relative risk (IRR) for CD4 cell count<50 cells/µL: 41.70, p<0.001]. HL risk had been elevated during the 6 months after combination antiretroviral therapy (cART) initiation (IRR: 26.65, p<0.001). Twenty-two HIV-HL cases were matched to 3280 controls. In the year preceding HIV-HL diagnosis the mean change in CD4+ cell counts between cases and controls was significantly different (-99 cells/µL for cases vs. +37 cells/µL for controls, p<0.0001). Compared with the general population, HIV-infected patients showed an increased risk for developing HL. The risk of HIV-HL increased significantly in the first months after cART initiation.

Male breast cancer in an HIV-infected patient: a case report.

Male breast cancer is rare and few cases of breast cancer in human immunodeficiency virus (HIV)-infected patients are reported. We describe the case of breast cancer in a 65-year-old HIV-positive man who presented a nodule near the nipple of his left breast. He did not report risk factors for breast cancer, but he had liver cirrhosis. Biopsy of the lesion revealed a ductal carcinoma and he was submitted to mastectomy and axillary dissection. Staging resulted in pT1c/pN1a/M0; it was positive for the presence of oestrogen/progesterone receptors, negative for the human epidermal growth factor receptor-22. He was also treated with local radiotherapy and tamoxifen. At cancer diagnosis, he received highly active antiretroviral therapy (HAART) with undetectable HIV viral load, and his CD4+ T-cell count was 445 cells/mm(3). Patients with HIV infection have a higher cancer risk due to immunosuppression: it concerns not only malignancies related to human acquired immunodeficiency syndrome (AIDS), but also other cancers. A heightened awareness of male breast cancer by HIV specialists is needed, especially for particular risk categories, such as trans-sexuals who take oestrogen therapies, and for the presence of breast conditions, such as gynecomastia, usually considered as part of the lipodystrophy syndrome.
