Real-life use of Doravirine in treatment-experienced people living with HIV: A multicenter Italian study.

Use of doravirine (DOR), a new nonnucleoside reverse-transcriptase inhibitors recently approved for HIV treatment, is still unclear in clinical practice and real-life data are scarce. We retrospectively investigated the rationale for switching people with HIV to DOR-containing/-based regimens in a real-life cohort. Among 132 patients (68.9% males, median age 56 years), the main reasons to start DOR were prevention of toxicities (39.4%) and dyslipidemia (18.2%). DOR was combined with integrase inhibitors in 40.9% cases, and in 25.7% of patients, DOR was prescribed without availability of a genotypic resistance test. Twenty-four weeks after the switch to DOR-containing/-based regimens, no significant changes in CD4+ T-cell count, CD4/CD8 ratio, detectable HIV-RNA, serum creatinine levels, and body weight were detected. By contrast, a significant reduction in lipids (both cholesterol and triglycerides) was observed in 52 patients for whom a follow-up assessment was available (P = .008 and .01, respectively). Our data confirmed that switching to DOR-containing/-based regimens may have a favorable impact on lipid profile and a neutral impact on weight gain. However, more data are needed to support its use in patients who do not have a genotypic test available or have an extensive nonnucleoside reverse-transcriptase inhibitors-associated resistance, as well as its use in a dual regimen, especially in combination with second-generation integrase inhibitors.

The Burden of Clostridioides Difficile Infection during the COVID-19 Pandemic: A Retrospective Case-Control Study in Italian Hospitals (CloVid).

Data on the burden of Clostridioides difficile infection (CDI) in Coronavirus Disease 2019 (COVID-19) patients are scant. We conducted an observational, retrospective, multicenter, 1:3 case (COVID-19 patients with CDI)-control (COVID-19 patients without CDI) study in Italy to assess incidence and outcomes, and to identify risk factors for CDI in COVID-19 patients. From February through July 2020, 8402 COVID-19 patients were admitted to eight Italian hospitals; 38 CDI cases were identified, including 32 hospital-onset-CDI (HO-CDI) and 6 community-onset, healthcare-associated-CDI (CO-HCA-CDI). HO-CDI incidence was 4.4 × 10,000 patient-days. The percentage of cases recovering without complications at discharge (i.e., pressure ulcers, chronic heart decompensation) was lower than among controls (p = 0.01); in-hospital stays was longer among cases, 35.0 versus 19.4 days (p = 0.0007). The presence of a previous hospitalisation (p = 0.001), previous steroid administration (p = 0.008) and the administration of antibiotics during the stay (p = 0.004) were risk factors associated with CDI. In conclusions, CDI complicates COVID-19, mainly in patients with co-morbidities and previous healthcare exposures. Its association with antibiotic usage and hospital acquired bacterial infections should lead to strengthen antimicrobial stewardship programmes and infection prevention and control activities.

Abacavir adverse reactions related with HLA-B*57: 01 haplotype in a large cohort of patients infected with HIV.

OBJECTIVE: Carriage of human leukocyte antigen (HLA)-B*57:01 allele increases the risk of abacavir hypersensitivity reaction. Therefore, since 2008 HIV treatment guidelines recommend HLA-B*57:01 screening before abacavir administration, greatly reducing hypersensitivity reaction rate. However, clinically suspected abacavir-related hypersensitivity reactions are described in allele non-carriers. Major aim of this study was to evaluate the relationship between HLA-B*57:01 pattern and abacavir-related hypersensitivity reaction, focusing on hypersensitivity reaction prevalence in allele non-carriers. METHODS: We included all outpatients aged >18 years old with HIV infection and known HLA-B*57:01 pattern, followed at our Department from January 2000 until December 2017. Patients were divided according to HLA-B*57:01 pattern and first antiretroviral treatment prescribed (containing or not abacavir) as follows: HLA-B*57:01 allele carriers treated with abacavir and HLA-B*57:01 allele non-carriers treated with abacavir. We considered all adverse events reported during first abacavir administration, differentiating between confirmed hypersensitivity reactions and non-hypersensitivity reactions, according to abacavir hypersensitivity reaction definition included in the abacavir EU Summary of Product Characteristics and the US Prescribing Information. RESULTS: A total of 3144 patients had a known HLA-B*57:01 pattern. About 5.4% of them showed allele polymorphism; Caucasian ethnicity was the most represented. In this cohort, 1801 patients were treated with a first abacavir-containing regimen (98.2% of them was represented by allele non-carriers). 191 out of 1801 patients discontinued abacavir because of toxicity/intolerance; among them 107 described adverse events fulfilled the criteria of confirmed abacavir hypersensitivity reaction (22/32 allele-positive patients and 85/1769 allele-negative patients). After having experienced a confirmed abacavir hypersensitivity reaction, abacavir was re-administered to eight HLA-B*57:01 negative patients. Seven of them re-experienced a syndrome consistent with hypersensitivity reaction, finally leading to drug discontinuation. Overall, no fatal reactions were described. CONCLUSION: Not all abacavir-related side effects occur as a result of classic HLA-B*57:01-mediated hypersensitivity reaction, as they can develop irrespective of HLA-B*57:01 status. Clinical vigilance must be an essential part of the management of individuals starting abacavir, at any time during treatment. In a 'real-life' setting, clinical diagnosis of suspected abacavir hypersensitivity reaction in allele non-carriers remains crucial for further clinical decision making.

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.

Incidence of cardiovascular events in HIV-positive patients compared to general population over the last decade: a population-based study from 2000 to 2012.

Cardiovascular diseases are currently a main cause of death among people living with HIV. This population-based study aimed to investigate the incidence of cardiovascular events (CVEs) in HIV-positive people and factors associated with CVEs. We performed a retrospective cohort study of the HIV-infected patients residing in the Local Health Authority of Brescia, northern Italy, from 2000 to 2012. Incidence of CVEs events in HIV-positive patients was compared with that expected in general population living in the same area, computing standardized incidence ratios (SIRs). CVEs-associated risk factors were assessed using Cox regression analysis and competing risk model of death. About 3766 HIV-infected patients were included in the study. Over the 12-year-period, we recorded 134 CVEs: 83 (61.9%) acute myocardial infarctions (CVE type-1), and 51 (38.1%) strokes (CVE type-2). A twofold increased risk (SIR = 2.02) of CVEs was found in HIV-infected patients compared to the general population. Notably, within male patients: for CVE type-1, SIR = 1.89, for CVE type-2 SIR = 2.25; within female patients: for CVE type-1, SIR = 2.91, for CVE type-2 SIR = 2.07. Age >45 years, male gender, diabetes, and total blood cholesterol >200 mg/dl were significantly associated with CVEs incidence (for all, p < .05). These results were confirmed using the competing risk model. Our cohort study confirmed the higher incidence of CVEs in HIV-positive patients, and put emphasis on the importance of traditional cardiovascular risk factors. Overall CVE risk in HIV-positive patients was twice as high as CVE risk in general population. We found a peculiar gender distribution, with a relative risk for CVE type-1 higher in HIV-positive females, and a higher CVE type-2 risk in male patients. More studies are needed in order to support these findings and to further highlight possible gender differences in the risk of developing CVEs in HIV-positive patients.

Neutrophil to Lymphocyte Ratio and Cardiovascular Disease Incidence in HIV-Infected Patients: A Population-Based Cohort Study.

Neutrophil to lymphocyte ratio (NLR) has been shown to predict occurrence of cardiovascular events in the general population. The aim of our study was to evaluate the role of NLR to predict major cardiovascular disease (CVD) events in HIV-infected subjects. We performed a retrospective cohort study of HIV-infected patients residing in the Local Health Authority (LHA) of Brescia, northern Italy, from 2000 to 2012. The incidence of CVD events in HIV-positive patients was compared with that expected in the general population living in the same area, computing standardized incidence ratios (SIRs). To evaluate the predictive role of NLR, univariate and multivariate Cox regression models were applied, computing hazard ratios (HRs). A total of 3766 HIV-infected patients (mean age 38.1 years, 71.3% males) were included (person-years 28768.6). A total of 134 CVD events occurred in 119 HIV-infected patients. A 2-fold increased risk (SIR 2.02) of CVD was found in HIV-infected patients compared to the general population. NLR levels measured at baseline and during follow-up were independently associated with CVD incidence, when also adjusting for both traditional CVD risk factors and HIV-related factors (HR 3.05 for NLR≥ 1.2). The area under the receiver operating characteristics (ROC) curve showed a modest, not statistically significant, increase, from 0.81 to 0.83, with addition of NLR to Framingham risk score model covariates. In conclusion an elevated NLR is a predictor of risk CVD in HIV-infected patients, independently from the traditional CVD risk factors.

Screening for Neurocognitive Impairment in HIV-Infected Individuals at First Contact after HIV Diagnosis: The Experience of a Large Clinical Center in Northern Italy.

Neurocognitive disorders are emerging, probably underestimated, complications in HIV-infected people. The aim of the study was to assess neurocognitive profiles of newly detected HIV-infected patients. We performed an observational retrospective single-cohort study. Illiterates and patients with neurologic symptoms or previous psychiatric diagnosis were excluded. Neuropsychological profiles were assessed using a validated battery of neuropsychological tests. We included 206 patients; with males representing the majority of them (85%). Risk factors for HIV acquisition were unprotected sexual intercourse (homo/bisexual in 39.8% and heterosexual in 60.2%). Thirty-nine patients (18.9%) were previous injection drug users, while 41 (19.9%) were alcohol abusers. Mean education was 11.1 years (SD--standard deviation--3.7). A high prevalence of HIV-associated neurocognitive disorders (HAND, 47.1%) was present in HIV-infected patients: particularly, asymptomatic neurocognitive impairment (ANI) was found in 30.6%, mild neurocognitive disorder (MND) in 15% and HIV-associated dementia (HAD) in 1.5%. Male gender, low degree of education, AIDS diagnosis and gepatitis B virus (HBV) co-infection were factors independently associated with HAND in a multivariable logistic regression model. Our data suggest that patient-specific factors and AIDS diagnosis have a certain kind of impact in HAND occurrence. A complete neuropsychological screening must be recommended in all patients at HIV-infection diagnosis.

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.

Celiac disease with mild enteropathy is not mild disease.

BACKGROUND & AIMS: Patients with celiac disease have varying degrees of damage to the small intestinal mucosa, ranging from lymphocytic duodenosis with normal villous structure to severe villous atrophy. We assessed whether the severity of mucosal lesions was associated with clinical and laboratory features of celiac disease. METHODS: We compared demographic, clinical, and laboratory characteristics among patients with celiac disease who were classified based on the severity of duodenal lesions. We analyzed data from 1408 adult patients seen consecutively at a tertiary referral center since 1990. Patients were classified as having villous atrophy (n = 1249) or as having mild enteropathy (n = 159) in the presence or absence of villous atrophy. RESULTS: Similar percentages of patients with villous atrophy, vs mild enteropathy, experienced weight loss (17% vs 17%), gastrointestinal manifestations (70% vs 70%), extraintestinal manifestations (66% vs 57%), and other associated conditions (19% vs 23%). More patients with villous atrophy than patients with mild enteropathy developed osteopenia or osteoporosis (22% vs 5%; P = .0005). Greater percentages of patients with villous atrophy than those with mild enteropathy also had anemia (42% vs 29%; P = .002), folate deficiency (75% vs 64%; P = .02), hypocholesterolemia (7% vs 2%; P = .02), hypocalcemia (26% vs 13%; P = .004), or hyperparathyroidism (45% vs 29%; P = .004). CONCLUSIONS: Although osteopenia, osteoporosis, and alterations in laboratory parameters are prevalent among patients with celiac disease with mild enteropathy, they are more prevalent and severe in those with villous atrophy. The prevalence of associated conditions is similar between these groups. These results indicate that celiac disease with mild enteropathy is not mild disease, but requires treatment with a gluten-free diet.

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.
