Geriatric Patients Living with HIV/AIDS (GEPPO) is a new prospective observational multicentre cohort consisting of all the HIV-positive geriatric patients being treated at 10 clinics in Italy, and ...HIV-negative controls attending a single geriatric clinic. The aim of this analysis of the GEPPO cohort was to compare prevalence and risk factors of individual non-communicable diseases (NCD), multi-morbidity (MM) and polypharmacy (PP) amongst HIV positive and HIV negative controls at enrolment into the GEPPO cohort.
This cross-sectional study was conducted between June 2015 and May 2016. The duration of HIV infection was subdivided into three intervals: < 10, 10-20 and > 20 years. The NCD diagnoses were based on guidelines defined criteria, including cardiovascular disease, hypertension, type 2 diabetes, chronic kidney disease, dyslipidaemia, chronic obstructive pulmonary disease. MM was classified as the presence of two or more co-morbidities. The medications prescribed for the treatment of comorbidities were collected in both HIV positive and HIV negative group from patient files and were categorized using the Anatomical Therapeutic Chemical (ATC) classification. PP was defined as the presence of five or more drug components other than anti-retroviral agents.
The study involved a total of 1573 patient: 1258 HIV positive and 315 HIV negative). The prevalence of individual comorbidities was similar in the two groups with the exception of dyslipidaemia, which was more frequent in the HIV-positive patients (p < 0.01). When the HIV-positive group was stratified based on the duration of HIV infection, most of the co-morbidities were significantly more frequent than in control patients, except for hypertension and cardiovascular disease, while COPD was more prevalent in the control group. MM and PP were both more prevalent in the HIV-positive group, respectively 64% and 37%.
MM and PP burden in geriatric HIV positive patients are related to longer duration of HIV-infection rather than older age per se.
Purpose
We evaluated if, during lithotripsy, bacteria may be detected in the irrigation fluid of percutaneous nephrolithotomy (PCNL) and retrograde intrarenal surgery (RIRS). The concordance between ...urine culture from stone fragmentation (SFUC), bladder (BUC), renal pelvic (RPUC) and stone (SC) was analyzed. We also assessed the correlation between variables and cultures and their association with systemic inflammatory response syndrome (SIRS) and of a positive SC.
Methods
We included 107 patients who underwent PCNL (
n
= 53) and RIRS (
n
= 54) from January 2017 to May 2018. Samples for RPUC were obtained by renal catheterization. Stone fragments and irrigation fluid sample were sent for culture.
Results
SFUC was positive in 17 (15.9%), BUC in 22 (20.6%), RPUC in 26 (24.3%) and SC in 30 patients (28%). The concordance between SFUC and SC was the highest among all cultures: 94.1%. SFUC and SC grew identical microorganisms in 15/17 (88.2%) patients. Out of 17 (15.9%) patients with SIRS, 8 (7.5%) had sepsis. SFUC had the highest PPV and specificity to detect positive SC and SIRS. Previous urinary tract infection, a preoperative nephrostomy, stone diameter and composition, staghorn calculi, PCNL, positive BUC, RPUC and SFUC were predictors of infected stone. Variables that indicate complex stones, complex PCNL and an infection of the upper tract were associated with SIRS.
Conclusion
SFUC is technically feasible, easy to retrieve and to analyze. The spectrum of SFUC potential application in clinical practice is when is not possible to perform a SC, e.g. complete dusting or during micro-PCNL.
Atopic dermatitis (AD) is a common inflammatory skin disease characterized by xerosis, pruritus and eczema. The role of probiotics in the prevention and the treatment of AD have been extensively ...studied in children with controversial results while there are few studies on an adult population. The aim of this randomized, double-blind, placebo-controlled study is to evaluate the clinical efficacy of the intake of a probiotic strain (Lactobacillus salivarius LS01) in the treatment of adult patients with AD. A group of 38 patients was treated with probiotics or placebo (maltodextrin) for 16 weeks. The study was performed from January (T0) to May, 2009 (T16). The assessment of efficacy was based on change in SCORAD (SCORing Atopic Dermatitis) index, dermatology life quality index (DLQI) improvement, cytokine production by PBMCs and ability to modify faecal microbial flora. No significant adverse events were recorded during the study. Patients treated with probiotics showed a statistically improvement of both clinical parameters (SCORAD p< 0.0001 and DLQI p= 0.021) at the end of treatment (T16) compared with the placebo group. Furthermore, after four months of treatment there was a significant reduction of Th1 cytokines (IL-12+IFNγ) (p= 0.03) and Th1/Th2 ratio (IL-12+IFNγ/IL-4+IL-5) (p= 0.019) only in placebo-treated patients. A statistically relevant decrease of staphylococci in faeces of the probiotic-treated group was also observed at the end of treatment. In our study, the administration of L. salivarius LS01 was well tolerated and was associated with a significant improvement of clinical manifestation and QoL. This probiotic strain could have an important role in modulating Th1/Th2 cytokine profiles and could be considered as an important adjunctive therapy in the treatment of adult AD.
Highlights • Community-acquired adenovirus pneumonia can rapidly progress to respiratory failure. • Single dose of cidofovir therapy was effective, but was associated with severe neutropenia. • ...Multiplex real-time PCR is a valuable tool to identify the virus responsible for clinical syndrome. • Adenoviruses should be included in the diagnostics panel also in patients with severe respiratory infection.
Introduction
After the introduction of highly active antiretroviral treatment, the course of HIV infection turned into a chronic disease and most of HIV-positive patients will soon be over 50 years ...old.
Material and methods
This paper reviews the multiple aspects that physicians have to face while taking care of HIV-positive ageing patients including the definitions of frailty and the prevalence and risk factors of concomitant diseases. From a therapeutic point of view pharmacokinetic changes and antiretroviral-specific toxicities associated with ageing are discussed; finally therapeutic approaches to frailty are reviewed both in HIV-positive and negative patients.
Conclusion and discussion
We conclude by suggesting that the combined use of drugs with the least toxicity potential and the promotion of healthy behaviours (including appropriate nutrition and exercise) might be the best practice for ageing HIV-positive subjects.
We described a case of a 56 year old homosexual HIV positive man who presented a history of CSU since one year (2012). All the allergologic, immunologic and microbiologic tests to evaluate the ...pathogenesis of wheals resulted negative. Therefore in June 2015 we decided to start therapy with Omalizumab while the patient kept on effective antiretroviral therapy with 310 cells/mm3 TCD4 counts and undetectable HIV viremia. After two monthly subcutaneuous injection of 150 mg of Omalizumab the patient had no more urticarial symptoms. UAS7 (Urticaria Activity Score over 7 days) and Cu-Q2oL (chronic urticarial quality of life questionnaire) dropped respectively to 14 from 42 and to 0 from 40 with increase of TCD4 counts while viral load remained undetectable. In November 2015, i.e. 4 months after the end of Omalizumab therapy, the patient was still asymptomatic with persistent effective immune-virological response to antiretroviral therapy. This case report confirms the excellent tolerability and efficacy of anti-IgE therapy in the treatment of spontaneous chronic urticarial even in an immunodepressed patient for HIV infection. Omalizumab therapy shows a remarkable clinical success and had no effect on peripheral TCD4 counts and HIV viral load.
Abstract Although survival after liver transplantation (LT) has progressively improved over the last years, an increased prevalence of clinically relevant infections in LT patients is well ...documented. In particular, the spread of infections sustained by extensively drug-resistant bacteria (XDR) produced an increase in the incidence of wound infections. Implementation of treatments for these life-threatening events is mandatory. This study describes 2 LT patients in whom XDR wound infection was effectively treated using negative pressure wound treatment (NPWT) combined with targeted local and systemic antibiotic therapy. Over the last 3 years, 2 of 8 patients with XDR infection admitted to our unit developed wound infection caused by XDR Klebsiella pneumoniae (KP-XDR). Positive results of the abdominal fluid culture and of the wound swab for KP-XDR were followed by sepsis. In both cases wound debridement was required and deep fascial layer dehiscence was detected. Combination antibiotic therapy was administered for sepsis treatment and, after failure of conventional NPWT, a NPWT with local instillation (NPWTi; V.A.C.-Ulta/VeraFlo-Instillation Therapy-KCI USA, Inc., San Antonio, TX, USA) of colistin-rifampicin was applied. After NPWTi application a reduction in bacterial load and exudate was observed with reduction in inflammatory markers. A complete healing of wound was achieved and both patients are currently alive. Instillation and NPWT are widely discussed in the literature. Results of the present study indicate beneficial effects of NPWT combined with targeted local and systemic antibiotic therapy; in both cases a life-threatening complication was cured. We consider local instillation of selected antibiotics applied to NPWTi a valuable tool for deep wound infection sustained by XDR bacteria.
HIV-1-specific IgA has been described in the genital tract and plasma of HIV-1 highly exposed, persistently seronegative (HEPS) individuals, and IgA from these sites has been shown to neutralize ...HIV-1. This study examines the ability of IgA isolated from HEPS individuals to inhibit transcytosis across a tight epithelial cell layer. A Transwell system was established to model HIV-1 infection across the human mucosal epithelium. The apical-basolateral transcytosis of primary HIV-1 isolates across this mucosal model was examined in the presence and the absence of IgA isolated from the genital tract, saliva, and plasma of HEPS individuals enrolled in both a sex worker cohort in Nairobi, Kenya, and a discordant couple cohort in Italy. In the absence of IgA, HIV-1 primary isolates were actively transported across the epithelial membrane and were released on the opposite side of the barrier. These transcytosed HIV-1 particles retained their ability to infect human mononuclear cells. However, IgA purified from the mucosa and plasma of HEPS individuals was able to inhibit HIV-1 transcytosis. Inhibition was seen in three of six cervicovaginal fluid samples, five of 10 saliva samples, and three of six plasma samples against at least one of the two primary HIV-1 isolates tested. IgA from low risk, healthy control subjects had no inhibitory effect on HIV-1 transcytosis. The ability of mucosal and plasma IgA to inhibit HIV-1 transcytosis across the mucosal epithelium may represent an important mechanism for protection against the sexual acquisition of HIV-1 infection in HEPS individuals.
