Objectives: We aimed to develop and validate a risk score to predict severe respiratory failure (SRF) among patients hospitalized with coronavirus disease-2019 (COVID-19). Methods: We performed a multicentre cohort study among hospitalized (>24 hours) patients diagnosed with COVID-19 from 22 February to 3 April 2020, at 11 Italian hospitals. Patients were divided into derivation and validation cohorts according to random sorting of hospitals. SRF was assessed from admission to hospital discharge and was defined as: SpO2 30 breaths/min or respiratory distress. Multivariable logistic regression models were built to identify predictors of SRF, β-coefficients were used to develop a risk score. Trial Registration NCT04316949. Results: We analysed 1113 patients (644 derivation, 469 validation cohort). Mean (±SD) age was 65.7 (±15) years, 704 (63.3%) were male. SRF occurred in 189/644 (29%) and 187/469 (40%) patients in the derivation and validation cohorts, respectively. At multivariate analysis, risk factors for SRF in the derivation cohort assessed at hospitalization were age ≥70 years (OR 2.74; 95% CI 1.66–4.50), obesity (OR 4.62; 95% CI 2.78–7.70), body temperature ≥38°C (OR 1.73; 95% CI 1.30–2.29), respiratory rate ≥22 breaths/min (OR 3.75; 95% CI 2.01–7.01), lymphocytes ≤900 cells/mm3 (OR 2.69; 95% CI 1.60–4.51), creatinine ≥1 mg/dL (OR 2.38; 95% CI 1.59–3.56), C-reactive protein ≥10 mg/dL (OR 5.91; 95% CI 4.88–7.17) and lactate dehydrogenase ≥350 IU/L (OR 2.39; 95% CI 1.11–5.11). Assigning points to each variable, an individual risk score (PREDI-CO score) was obtained. Area under the receiver-operator curve was 0.89 (0.86–0.92). At a score of >3, sensitivity, specificity, and positive and negative predictive values were 71.6% (65%–79%), 89.1% (86%–92%), 74% (67%–80%) and 89% (85%–91%), respectively. PREDI-CO score showed similar prognostic ability in the validation cohort: area under the receiver-operator curve 0.85 (0.81–0.88). At a score of >3, sensitivity, specificity, and positive and negative predictive values were 80% (73%–85%), 76% (70%–81%), 69% (60%–74%) and 85% (80%–89%), respectively. Conclusion: PREDI-CO score can be useful to allocate resources and prioritize treatments during the COVID-19 pandemic.

as stated by Estébanez et al 1, incidence of dermatological affection in covid‐19 patients may be different than reported until now. Datas and evidences are building up every day and we wanted to add a contribution describing the case of a 67‐year‐old patient, caucasian, with moderate obesity, a history of alcoholism and various chronic morbidities. No drug allergy was referred. She was sent to ER due to progressive dyspnoea and fever: after RT‐PCR resulted positive to SARS‐CoV 2, she was admitted to hospital and then intubated a week later due to worsening of the respiratory condition.

Introduction: Prostate cancer is a very infrequent occurrence in persons aged 55 years or less, and it has been rarely reported in HIV-infected patients (10 overall cases so far); therefore, an increased incidence compared with the general population has not been established, although a younger age seems more frequent among population with HIV disease. Case report: We report a case of metastatic prostate cancer occurred in a 53-year-old HIV-infected man, admitted due to non-specific signs, and symptoms: impaired general conditions, fever, weight loss, fatigue, and exertional dyspnea. A remarkable anemia and an aortic systolic murmur were the prominent initial findings, while AIDS-related conditions were not suspected due to a sustained CD4+ count and a contained viremia, which never required antiretroviral therapy. Repeated red blood cell transfusions and an empiric, combined antimicrobial therapy were promptly carried out, under the suspicion of infectious endocarditis, but no appreciable improvement of clinical conditions was achieved. Subsequently, our patient complained not only of an increasingly severe pain at the root of his left thigh, together with overcoming dysuria and urgency, but also urinary tract infection that was rapidly ruled out. During the diagnostic workup for an HIV-associated fever of undetermined origin, a bone marrow biopsy disclosed a metastatic prostatic cancer, with elevated prostate specific antigen (PSA) and acid phosphate levels. An abdominal–pelvic ultrasonography and computerized tomographic scan allowed to detect a dyshomogeneous endopelvic expansive mass with extrinsic compression of the urinary bladder, and involvement of the last lumbar vertebra, large portions of pelvis, and the proximal epiphysis of the right femur. A skeleton scintigraphy pointed out multiple hypercaptation (areas of concentrated traces of radioactivity) areas with involvement of cranial, cervical, dorsal, lumbar, and sacral vertebrae, as well as the pelvis and upper portions of both femurs. Despite therapeutic attempts, our patient deceased after seven weeks due to an overwhelming disseminated intravascular coagulation (DIC). Conclusions: The non-specific clinical presentation of our case (mimicking other generalized or focal illnesses), and the final, lethal complication (DIC) pose striking problems related to the differential diagnosis during HIV disease, while the rapid evolution into an advanced, complicated, and widely metastatic disease with extensive bone marrow invasion which preceded the appearance of local signs–symptoms, and the lethal overwhelming DIC, deserves attention by specialists who care for HIV-infected subjects.

We report the case of an HIV-infected patient who has been followed for 20 years, and despite presenting with AIDS (due to three episodes of cryptococcosis plus one of Pneumocystis jirovecii pneumonia) who during subsequent years missed, refused or took with limited compliance all recommended medications, including combination antiretroviral therapy, and primary and secondary antimicrobial chemoprophylaxis against opportunistic infections. The unexpected clinical and laboratory stabilization of our patient paralleled a progressive increase in his peripheral CD4+ T-lymphocyte count (range 410–825 cells/mL) and a relatively controlled HIV viraemia (5970–44,000 HIV-RNA copies/mL). Such a recovery of sufficient immune competency after experiencing four episodes of severe AIDS-associated opportunistic infections, without reliable antiretroviral and antimicrobial support raises several questions.

Background It is still unclear whether the virological-immunological steady-state observed among the small number of HIVinfected patients defined “long-term non-progressors” may have a prolonged-undefined duration, or it simply represents the extremity of a gaussian curve, and the progression of HIV disease is therefore an unavoidable event. These subjects are actively investigated, to understand this prolonged infection latency, so that many studies focused on the viremia levels predictive of disease progression.

Methods An extremely infrequent episode of associated nasopharyngeal squamous adenocarcinoma plus an underlying actinomycosis occurred in a HIV-infected male patient (p) with a previous diagnosis of AIDS, treated with cART taken with insufficient adherence, so that a satisfactory immune system recovery (as expressed by a CD4+ count persistingly >400 cells/μL), was in contrast with a lowlevel persistance of detectable HIV viremia, and extensive genotypic drug resistance mutations.

A reversal of key HIV protease mutations against tipranavir has been observed in a patient undergoing a late salvage antiretroviral therapy. Our patient initially introduced tipranavir/ritonavir in absence of an optimized background and novel drug classes, and nevertheless he experienced a virological-immunological benefit. Our report is a contribution to the present debate around the role of each single HIV protease mutation, and the validation of mutational “scores” (like the so-called tipranavir weighted score), to be applied to last-generation protease inhibitor compounds initially targeted on patients with limited, residual therapeutic options.

A case of extremely prolonged non-progression of HIV-1 infection, characterized by 19 consecutive years of persistently undetectable viraemia (or no laboratory markers of HIV replication) is presented and discussed based on recent literature issues regarding virological and immunological outcome of the natural history of HIV-1 infection.

The case of a young woman suffering from multiple autoimmune-dysreactive disorders (including thyreoiditis, myasthenia gravis, thymectomy, Crohn's disease, and erythema nodosum), while undergoing steroideal therapy, was complicated by a severe infectious disorder (severe upper urinary tract infection). While the pathogenetic and clinical relationship between the different autoimmune-dysreactive complications is still unclear, and the supporting role of the frequent immunosuppressive treatment may add significantly to these risk factors, clinicians who are engaged in the management of these patients should be aware that multiple, concurrent or subsequent disorders might occur in these subjects, and also that severe infections might be of relevant concern.

A unique occurrence of two subsequent episodes of HIV-associated Cryptococcus neoformans followed by C. laurentii meningoencephalitis (successfully cured with fluconazole after demonstrated amphotericin B resistance) is presented and discussed. The available literature reported only two cases of HIV-associated C. laurentii infection to date, while a concurrent infection by C. neoformans and C. laurentii has been reported only once in a patient without HIV disease. The absence of prior descriptions of documented central nervous system infection by C. laurentii in non-HIV-infected patients is emphasized as well as the unpredictable in vitro and in vivo antifungal susceptibility of this non-neoformans Cryptococcus spp., and its apparent prevalence in hospitalized patients who received prior antifungal treatments. All epidemiologic, diagnostic, clinical, and therapeutic implications are discussed on the basis of the evolving characteristics of opportunism in the era of highly active antiretroviral therapy (HAART).

The aims of the study were to evaluate the HIVAb, HCVAb and HBsAg seroprevalence among Italian and foreign inmates of the prison of Bologna, to evaluate if the extensive counselling of "new" inmates has significantly enhanced adherence to laboratory tests.The serological status was determined by a blood withdraw following the informed consent. Before asking their consent, patients were informed by cultural mediators who had been instructed about the aims of the study/exam during introductory meetings. The initial step managed by mediators was followed by further individual counselling interventions, carried out by hospital infective disease unit, prison and prison drug abuse service physicians. The laboratory tests were performed in an external structure.Prison of Bologna.The study was conducted on 433 subjects among a whole population of 900 inmates in the local prison: 390 subjects were males (90.1%) and 43 were females (9.9%). The median age of the whole population was 34.86 years (+/- 9.9). The studied population counted 147 (33.9%) intravenous drug users (IDU) and 286 not addicts (66.1%). As regards nationality, 212 subjects were Italian (48.9%) and 221 (51.1%) foreigners. Among the total 433 inmates considered, 78 (18%) were known as previous IDU with conviction history or condemned to long term sentences, while 59 (13.6%) were inmates recently convicted active IDU assisted by the internal drug abusers service. The third group was composed by 296 inmates imprisoned during the summer (103 Italians and 193 foreigners) self declared not IDU.A. 12.5% of inmates were HIV positive, 8.1% HBV positive and 31.1% HCV positive. 25 subjects were found positive both to HIV and HCV; 1 both to HIV and HBV and 5 to HIV, HBV and HCV. HIV positivity is more common among Italian vs. foreigners inmates, among IDU vs. not IDU. HCV positivity is more common among Italian vs. foreigners inmates, and among IDU vs. not IDU. The distribution of HBV seropositivity among the different groups shows no statistically significant differences. All subjects receiving multi-focal counselling reached better compliance levels: 10% vs. 1% for HIV, 16% vs. 1% for HBV and 35% vs. 0.3% for HCV, with statistically significant coefficients of contingency.In the prison of Bologna drug addiction is prevalent in italian seropositive personers and it is often associated with HIV and HCV positivity. Foreign inmates, mostly in the not-IDU group, show a lower prevalence of these two infections. Multi-focal counselling before test increased significantly the adherence of inmates to the study.

At the current epidemic stage, characterized by the rise of antiretroviral drug resistance, it is necessary to administer to HIV-positive patients increasingly effective treatments. This is possible only by means of powerful drugs. In a retrospective study, the authors evaluate 78 patients: 76 pre-treated with multiple drugs and 2 na ves. The 78 patients received LPV/RTV, starting from the fourth 3-month period of 2000 until the first 3-month period of 2002. The average treatment duration was 6.5 ( 5.5) months; the median value 6 months. The efficacy of the LPV/RTV therapeutic regimen was evaluated by a cytofluorimetric count of CD4+ and determination of the HIV viral load. There were 14 drop-out patients (17.9%): 5 because of auto-suspension, 1 due to absence of clinical and virological efficacy, 5 due to side effects (3 hepatopathy, 1 allergy and 1 nausea); three patients were lost on follow-up. There were 64 (82.1%) patients on treatment. Forty patients responded (51.3%) and 13 (16.7%) had uncontrolled viraemia (over than 200 copies/ml). However, the treatment with LPV/RTV was not interrupted for these patients, because in the follow-up they showed an increase in CD4+ values. The authors conclude that the LPV/RTV combination confirms previous findings: it is a drug with a relatively low incidence of side effects, capable of powerful results even in the treatment of patients receiving multiple drugs and thus subjected to the risk of developing antiretroviral drug resistance.

A case of cervicofacial and pulmonary actinomycosis associated with non-Hodgkin's lymphoma (NHL) is reported. The patient underwent antimicrobial treatment and surgical debridement of a palatine lesion. Complete clinical recovery was achieved. The presence of actinomycosis may obscure and delay the diagnosis of NHL.
