RESUMO
BACKGROUND: New HIV diagnoses in Italy decreased drastically in 2020 due to COVID-19 related effects: 50% fewer diagnoses were reported by the National HIV Surveillance System. COVID-19 pandemic impact on HIV surveillance is unclear. We estimated the expected number of new HIV diagnoses in 2020 in order to isolate the impact of the COVID-19 pandemic. METHODS: We analyzed 29 697 new HIV infections diagnosed from 2012 to 2020, reported to the National HIV Surveillance System. We assessed temporal trends of new HIV diagnoses applying negative binomial mixed effects models. We estimated the COVID-19 impact as the difference between the model-estimated slopes from 2012 to 2019 and the change reported in the diagnoses. The expected number of new HIV diagnoses in 2020 was also estimated and compared with the reported count. RESULTS: Based on the historical trend, we expected a 15% (95% CI: 5-25%) decline of new HIV diagnoses in 2020. We reported, however, a 49% decrease, yielding to a 34% net decrease in the number of new diagnoses. The strongest impact was estimated in northern regions (-40%) and MSM (-38%). We estimated 761 (95% prediction interval: 350-1277) missed diagnoses during 2020, the majority of them occurring in the North (465 cases), among MSM (416) and heterosexual males (217). CONCLUSIONS: In 2020, when excluding 15% decrease of new diagnoses attributable to the expected reduction, an additional 34% decrease was observed, representing a large decline in new HIV diagnoses associated with the COVID-19 pandemic.

BACKGROUND: Schoolchildren screening for allergic diseases may improve early identification and management of atopic children. The aim of this study was to perform a schoolchildren screening program for identification of children with allergic diseases. METHODS: All parents of children attending to 13 primary schools in the city of Rome were requested to fill in a demographic data form and the ChAt questionnaire. Allergological evaluation was performed in the children with suspect of allergy (ChAt score > 2). Ocular examination was performed to identify signs of allergic conjunctivitis. The presence of allergic symptoms was related to demographic and environmental variables. RESULTS: A total of 2667 children (mean age: 7.1 ± 1 years) were included, and 2489 (93.3%) parents completed the ChAt questionnaire. Results of ChAt questionnaire showed a previous diagnosis of allergic disease in 637 (25.6%) children and the potential presence of an allergic disease (ChAt score > 2) in 35.1%. Multivariate analysis showed that older age, male gender, and having less than two siblings were associated with higher risk of allergic disease. Visual screening showed the presence of clinical signs of allergic conjunctivitis in 2% of children. Allergologic evaluation in 334 children confirmed the diagnosis of allergic disease in 324 (97%) cases. Among them, 97 (29.9%) did not refer to a previous formal diagnosis of allergic condition. CONCLUSIONS: This study confirmed that schoolchildren screening using ChAt questionnaire could represent a useful tool for early identification of yet undiagnosed atopic children.

BACKGROUND: Chronic diseases, chiefly cancers and circulatory system diseases (CSDs), have become the leading non-AIDS-related causes of death among HIV-infected people, as in the general population. After our previous report of an excess mortality for several non-AIDS-defining cancers, we now aim to assess whether people with AIDS (PWA) experience also an increased mortality for CSDs and diabetes mellitus (DM), as compared to the non-AIDS general population (non-PWA). METHODS: A nationwide, population-based, retrospective cohort study was conducted including 5285 Italians, aged 15-74 years, who were diagnosed with AIDS between 2006 and 2011. Multiple cause-of-death (MCoD) data, i.e. all conditions reported in death certificates, were retrieved through record-linkage with the National Register of Causes of Death up to 2011. Using MCoD data, sex- and age-standardized mortality ratios (SMRs) with 95% confidence intervals (CIs) were calculated by dividing the observed number of PWA reporting a specific disease among MCoD to the expected number, estimated on the basis of mortality rates (based on MCoD) of non-PWA. RESULTS: Among 1229 deceased PWA, CSDs were mentioned in 201 (16.4%) certificates and DM in 46 (3.7%) certificates among the various causes of death. These values corresponded to a 13-fold higher mortality related to CSDs (95% CI 10.8-14.4) and DM (95% CI: 9.5-17.4) as compared to 952,019 deceased non-PWA. Among CSDs, statistically significant excess mortality emerged for hypertension (23 deaths, SMR = 6.3, 95% CI: 4.0-9.4), ischemic heart diseases (39 deaths, SMR = 6.1, 95% CI: 4.4-8.4), other forms of heart diseases (88 deaths, SMR = 13.4, 95% CI: 10.8-16.5), and cerebrovascular diseases (42 deaths, SMR = 13.4, 95% CI: 9.7-18.2). The SMRs were particularly elevated among PWA aged < 50 years and those infected through drug injection. CONCLUSIONS: The use of MCoD data disclosed the fairly high mortality excess related to several CSDs and DM among Italian PWA as compared to non-PWA. Study findings also indicate to start preventive strategies for such diseases at a younger age among AIDS patients than in the general population and with focus on drug users.

BACKGROUND: the Italian National HIV Surveillance, instituted by the Ministerial Decree of March 31st, 2008, is based on 21 regional surveillance systems and adopts an essential data collection form with a definite data flow. The unification of HIV and AIDS surveillance systems and the implementation of an identical data collection form are priorities of the Italian National HIV/AIDS Action Plan 2017 (PNAIDS). OBJECTIVES: to describe the 21 regional HIV surveillance systems and to verify the feasibility of their unification. METHODS: in March 2017, a questionnaire containing 13 questions was sent to all the regional representatives of the 21 surveillance systems. The main questions were about timeliness, data flow, and quality of the system. The quality was measured through a subjective evaluation expressed by the regional referent through scores from 1 (minimum) to 10 (maximum) regarding four indicators (regional coverage, timeliness, correctness, and completeness of the data). RESULTS: more than half of the regional systems use a computerized data collection method. Some of these regions have not completely adapted to the data collection form contained in the Decree and other regions declare a undernotification of the system. The majority of the regions record a slight notification delay by the reporting centres. Some regions report gaps in the completeness of the data received by the reporting centres. CONCLUSIONS: the main strengths of the HIV surveillance system are computerization of the systems and slightly reporting delay. Regarding the quality of the regional systems and its data, the study reports a good self-evaluation. This study also showed useful indications to improve the national HIV surveillance system, such as the unification of HIV surveillance with the AIDS surveillance and the implementation of a unique national system, as suggested by guidelines of the PNAIDS 2017.

INTRODUCTION: Sexually transmitted infections (STIs) represent a group of widespread infectious diseases. The objective of this study is to investigate the knowledge on HIV and STIs as well as sexual risk behaviours among blood donors in Italy. MATERIALS AND METHODS: The study was carried out in 2017 among blood donors who accessed social media of the Italian Association of Blood Donors (Associazione Volontari Italiani del Sangue, AVIS), and answered to a questionnaire posted online. RESULTS: Participating blood donors were 9,021, median age 36 years (IQR 26-47), 53.9% males, 94.3% heterosexual, and 2.7% reported having a current occasional partner. Unprotected sex in the last 4 months was reported by 54.1% of participants. About half of the participants were not informed of most STIs, 11.0% reported never having searched for information on HIV and STIs, one third considered unlikely acquiring HIV through unprotected sex with a known person, 21.3% would stop having sex with a partner found to be HIV-positive, and 15.8% would be afraid to hug or kiss a person with HIV. DISCUSSION: Our results show that most blood donors have a stable partner and search actively for information on HIV and STIs. However, there is a proportion of them who engage in high-risk behaviours, have misconceptions on HIV and STIs transmission, reporting a stigmatising attitude towards people with HIV. CONCLUSION: A more comprehensive and updated information on various STIs, transmission modes and safe sex should be provided to blood donors, not only to prevent the spread of these infections but also to avoid unjustified discrimination.

OBJECTIVES: This study aimed to assess whether an excess mortality related to kidney and other urinary tract diseases exists among Italian people with AIDS (PWA), as compared with the general population without AIDS (non-PWA). DESIGN: Population-based, retrospective cohort study. SETTING AND PARTICIPANTS: We conducted a nationwide study including 9481 Italian PWA, aged 15-74 years, reported to the National AIDS Registry between 2006 and 2018. METHODS: Vital status and causes of death were retrieved by record linkage with the National Register of Causes of Death up to 2018. Excess mortality for PWA versus non-PWA was estimated through sex-standardised and age-standardised mortality ratios (SMRs) with corresponding 95% CIs. RESULTS: Among 2613 deceased PWA, 262 (10.0%) reported at least one urinary tract disease at death, including 254 (9.7%) non-cancer diseases-mostly renal failures (225 cases, 8.6%)-and 9 cancers (0.3%). The overall SMR for non-cancer urinary tract diseases was 15.3 (95% CI 13.4 to 17.3) with statistically significant SMRs for acute (SMR=22.3, 95% CI 18.0 to 27.4), chronic (SMR=8.4, 95% CI 6.0 to 11.3), and unspecified renal failure (SMR=13.8, 95% CI 11.2 to 16.8). No statistically significant excess mortality was detected for urinary tract cancers (SMR=1.7, 95% CI 0.8 to 3.3). The SMRs were particularly elevated among PWA aged <50 years, injecting drug users, or those with the first HIV-positive test >6 months before AIDS diagnosis. CONCLUSIONS: The excess mortality related to non-cancer kidney and other urinary tract diseases reported among PWA highlights the importance of implementing the recommendation for screening, diagnosis and management of such conditions among this population.

AIMS: To assess whether the use of multiple cause-of-death data could improve reporting of AIDS mortality in Italy. METHOD: Population-based, record-linkage study, on 3,975,431 deaths recorded in the National Registry of Causes of Death (RCoD) and 4,530 deaths recorded in the National AIDS Registry (RAIDS), during 2006-2012. RESULTS: The record-linkage identified 3,646 AIDS-related deaths present in both registries, 884 deaths in the RAIDS without mention of HIV/AIDS in the RCoD, and 3,796 deaths in the RCoD with mention of HIV/AIDS that were not present in the RAIDS. In the latter, in-depth analysis of multiple cause-of-death allowed the identification of 1,484 deaths that were AIDS-related. On these results, we estimated 6,014 deceased people with AIDS. Of them, 14.7% (884) were not present in the RCoD and 24.7% (1,484) derived from the RCoD only. CONCLUSIONS: The integration of different nationwide registries allowed a more comprehensive estimate of the impact of AIDS-associated mortality in Italy.
