Clinical impact of rapid viral respiratory panel testing on pediatric critical care of patients with acute lower respiratory infection

BackgroundWe aimed to determine the impact of utilizing a rapid panel test of respiratory viral and atypical bacteria (FilmArray® Respiratory Panel, FA RP) on etiological diagnosis of acute lower respiratory infection (ALRI) and antimicrobial stewardship in critical care pediatric patients.MethodsProspective cohort study of patients aged < 18 years with clinical diagnosis of ALRI that were admitted to the Pediatric Intensive Care Unit (PICU) of Hospital Sant Joan de Deu (Barcelona, Spain) during December 2015–February 2017. Patients were diagnosed by FA RP and by a bundle of routine microbiological assays.ResultsALRI viral and bacterial etiology was confirmed by a composite reference standard of routine microbiological assays in 72 (55.4%) and 15 (11.5%) respiratory samples, respectively, that were collected from 130 children (median age, 3.5 months, IQR 1.1–14.8 months; 54.6% male). Comparatively, FA RP use increased etiological confirmation of ALRI in up to 123 (94.6%) samples (p < 0.001) but only determined a bacterial origin in 2 (1.5%). Availability of diagnostic results before patient discharge from the PICU rose from 65.4 to 38.5% (p < 0.001). Use of the new panel test directly influenced antimicrobial stewardship in 11 (8.4%) episodes, leading to discontinuation of antiviral drugs (n = 5), administration of targeted antibiotics (n = 3), antiviral therapy start (n = 2) and both targeted antibiotic administration and discontinuation of antiviral drugs (n = 1).ConclusionFA RP contributed to improve etiological diagnosis of ALRI in a timely manner while enhancing a more rational use of antimicrobial drugs in critical care pediatric patients.     

Neurocognitive and quality of life study in perinatally HIV-infected young people and their peers. NeuroCoRISpeS study

BackgroundAssessing the role of HIV and non-HIV related factors is essential for a better understanding of the neurocognitive outcomes in perinatally HIV-infected (PHIV+) young people. The aim of our study was to assess cognition and quality of life (QoL) of a PHIV+ cohort of young people and to compare it with a control group.MethodsThirty PHIV+ and 30 HIV(−) healthy young adults matched by age, sex and socioeconomic status completed a protocol that included neurocognitive tests, a psychosocial semi-structured interview and a QoL questionnaire (PedsQL). Neurocognitive domain-specific and domain-general (NPZ-5) Z-scores were calculated. CDC AIDS-defining category C or not C (PHIV+/C, PHIV+/noC) was considered to evaluate differences within the PHIV+ group. Univariate and multivariate analysis were performed.ResultsSixty patients were included; 67% were female; median age (IQR) 19 years (18–21). Regarding PHIV+ young people, 27% showed CDC C category (none encephalopathy), 93% were on ART and 77% had undetectable viral load. No differences regarding occupation were found, although the HIV(−) group repeated less grades (p = 0.028) and had a higher education level (p = 0.021).No differences were found between PHIV+/noC and HIV(−) participants. However, the PHIV+/C group showed poorer performance than PHIV+/noC (NPZ-5, p = 0.037) and HIV(−) subjects (crystallised intelligence, p = 0.025; intelligence quotient, p = 0.016). Higher nadir CD4+ T-cell count was related to better Z-score in memory (p = 0.007) and NPZ-5 (p = 0.025). Earlier and longer exposure to ART resulted in better performance in memory (p = 0.004) and executive functions (p = 0.015), respectively.ConclusionsNo significant differences were found in the neurocognitive profile nor QoL between PHIV+/noC and HIV(−) adolescents; however, PHIV+/C participants obtained lower scores. The use of longer and earlier ART seems to have a beneficial effect.     

Syphilis and HIV-1 among parturient women in Salvador,Brazil: low prevalence of syphilis and high rate of loss to follow-up in HIV-infected women

BackgroundThe occurrence of syphilis and HIV-1 infections during pregnancy are major risks to the fetus due to mother-to-child transmission (MTCT).ObjectivesTo determine peripartum seroprevalence and risk factors of syphilis and HIV-1 infection among pregnant women in Salvador, Brazil, and the rate of HIV-1 MTCT.MethodsCross-sectional study of pregnant women who were admitted for delivery in a reference maternity hospital between May 2008 and March 2009 was conducted. Women were screened for HIV-1 infection and syphilis, and interviewed regarding demographic, behavioral and obstetric data. Newborns to HIV-infected mothers were tested by b-DNA and DNA-PCR to detect HIV-1.ResultsA total 3300/8516 women were evaluated. Mean age was 25.8 ± 7.3 years. HIV-1 and syphilis seroprevalence rates were 0.84% (28/3300) and 0.51% (17/3300), respectively. HIV-1 infection was associated with: low education (p = 0.04), having a partner with known HIV infection (p < 0.0001) or with previous sexually transmitted infection (p < 0.0001), blood transfusion (p = 0.003), or accidental exposure to blood (p = 0.003). Syphilis was associated with being Caucasian (p = 0.02), having no steady partner (p = 0.02), being a housewife (p = 0.01), having an intravenous drug user (IVDU) sexual partner (p = 0.04) or a sexual partner with previous STI (p < 0.001). Higher education (p = 0.04) was protective against HIV-infection. Attending a prenatal care program was protective against syphilis (p = 0.008) and HIV-1 (p = 0.02). No case of HIV-1 MTCT was detected, but 25% of children born to HIV-infected mothers were lost to follow up.ConclusionsIn Salvador, peripartum prevalence of syphilis and HIV-1 infection among pregnant women were low, and associated with classic risk factors for both infections. The great proportion of very late diagnosis of HIV infection, and the high rate of loss of follow-up among positive mothers and their infants are of high concern.     

Prevalence and risk factors of osteopenia/osteoporosis in Turkish HIV/AIDS patients

BackgroundRecent studies showed a high frequency of low bone mineral density (BMD) in HIV-infected patients and no reports have been issued in Turkey. Our aim was to evaluate BMD and risk factors for osteopenia/osteoporosis in HIV-infected patients that attended an outpatient clinic in Istanbul, Turkey.MethodIn order to determine the prevalence of BMD, 126 HIV-infected patients had been studied with dual energy X-ray absorptiometry (DEXA). The association between BMD and age, gender, body mass index (BMI), habits, 25(OH)vitamin D, HIV RNA, CD4 lymphocyte nadir, using and duration of highly active antiretroviral treatment (HAART) were investigated by using multivariate analysis.ResultsMedian age was 40.1 years (range, 20–70); 84% were male; 35.7% patients had AIDS, 63.5% were treated with HAART. Osteopenia and osteoporosis were diagnosed in 53.9% and 23.8%, respectively. Mean plasma HIV RNA was 5.2 (SD 1.0) log₁₀ copies/mL and CD4 lymphocyte nadir was 313.8 (SD 226.2)/mm³. Factors associated with bone loss were high viral load (p = 0.034), using (p = 0.033) and duration of HAART (p = 0.008). No correlation had been seen between sex and osteopenia/osteoporosis (p = 0.794). However, males showed higher rates of osteoporosis than females (p = 0.042).ConclusionsOur results show a very high prevalence of bone mass reduction in Turkish HIV-infected patients. This study supports the importance of both HIV and antiretroviral therapy in low BMD.     

Prevalence of metabolic syndrome assessed by IDF and NCEP ATP 111 criteria and determinants of insulin resistance among HIV patients in the Eastern Cape Province of South Africa

AimsTo determine the prevalence of metabolic syndrome (MS) and insulin resistance (IR) and their determinants in HIV on ART, ART naive HIV and HIV negative patients.MethodsCross sectional study. ART experienced HIV, ART naive HIV and HIV negative patients were compared for differences in prevalence of MS and IR. Determinants of MS and IR were assessed.ResultsPrevalence of MS by NCEP criteria was 26.6%, 15.7% and 21.9% (P = 0.3) respectively for HIV on ART, ART naive HIV and HIV negative groups. The MS rates with the IDF definition were 22.7%, 23.2% and 19.3% (P = 0.8) for HIV on ART, ART naive HIV and HIV negative patients respectively. Increased waist circumference by IDF criteria (P = 0.03), visceral to subcutaneous fat ratio (P = 0.049), hypertriglyceredemia (P < 0.001) and high LDL-Cholesterol (P < 0.001) were more common in HIV patients on ART than other groups. IR was found in 12.8%, 3.6% and 2.4% (P = 0.003) of HIV on ART, ART naive HIV and HIV negative groups respectively. Male gender (odds ratio (OR) 11 95% CI 3–48; P < 0.001) was independently associated with MS. HIV patients on ART (OR 6.6 95% CI 1.3–32.3; P = 0.020), IDF definition of MS (OR 3.4 95% CI 1.1–10.7; P = 0.040), NCEP definition of MS (OR 3.2 95% CI 1.01–10.3; P = 0.049) and low HDL-Cholesterol (OR 5.7 95% CI 1.2–27; P = 0.029) were independently associated with IR.ConclusionPrevalence of MS with IDF and NCEP definitions was similar across groups. HIV patients on ART and MS were independently associated with IR while male gender was independently associated with MS.     

Hypoadiponectinemia in lipodystrophic HIV individuals: A metabolic marker of subclinical cardiac damage

Background and aimTo evaluate cardiovascular abnormalities in highly active antiretroviral therapy (HAART) treated HIV patients with no signs or symptoms of cardiovascular impairment, and to assess the relative role of multiple concomitant risk factors.Methods and resultsForty-four consecutive HIV subjects (mean age 41 ± 6 yrs) were enrolled. Inclusion criteria were HIV infection, CD4 + cell count > 150/ml, HAART treatment for at least 4 years. Metabolic serum levels, morphological and functional echocardiographic parameters were assessed in all subjects. Sixteen healthy age and sex matched subjects with no cardiovascular risk factors were recruited as controls.HIV patients showed increased left ventricular mass index with reduced mid-wall fractional shortening (mFS) when compared to controls (50.2 ± 10.5 vs. 38.6 ± 14.4, p = 0.05 and 18.3 ± 0.6 vs. 21.9 ± 0.7, p < 0.05, respectively). Twenty-nine patients were lipodystrophic (LD) and showed a longer HAART period (p = 0.0004) and greater use of protease inhibitors (PI) (p = 0.001). Coronary flow reserve (CFR) was significantly reduced in HIV patients as compared to controls (p < 0.0001), as it was in LD subjects when compared to non-lipodystrophic ones (NLD) (p < 0.001). Adiponectin concentrations were found to be significantly lower in LD subjects than in NLD ones (7.8 ± 0.8 vs. 13.8 ± 1.2 μg/ml, p = 0.01), and showed a direct correlation with CFR. In multiple regression analysis, insulin, HDL and adiponectin accounted for 63% of CFR variations.ConclusionsLeft ventricular hypertrophy, depressed mFS and reduced CFR represent the main signs of subclinical cardiac damage in HIV subjects treated with HAART. Hypoadiponectinemia in these subjects seems to be a metabolic risk factor of cardiovascular impairment.     

Systemic inflammatory response syndrome in patients with liver cirrhosis

Background and study aimsPatients with liver cirrhosis present an increased susceptibility to the systemic inflammatory response syndrome (SIRS), which is considered the cause of hospital admission in about 10% of patients and is present in about 40% of those admitted for ongoing complications. We tried to assess the prevalence of the SIRS with the possible effects on the course of the disease during hospital stay.Patients and methodsTwo hundred and three patients with liver cirrhosis were examined and investigated with close monitoring during hospital stay. The main clinical endpoints were death and the development of portal hypertension-related complications.ResultsEighty-one patients met the criteria of SIRS (39.9%). We found significant correlations between SIRS and jaundice (p = 0.005), bacterial infection (p = 0.008), white blood cell count (p < 0.001), low haemoglobin concentration (p = 0.004), high serum creatinine levels (p < 0.001), high alanine aminotransferase levels (p < 0.001), serum bilirubin levels (p < 0.001), international normalised ratio (p < 0.001), serum albumin levels (p = 0.033), high Child-Pugh score (p < 0.001). During the follow-up period, 26 patients died (12.8%), 15 developed portal hypertension-related bleeding (7.3%), 30 developed hepatic encephalopathy (14.7%), and 9 developed hepatorenal syndrome type-1 (4.4%). SIRS showed significant correlations both to death (p < 0.001) and to portal hypertension-related complications (p < 0.001).ConclusionThe systemic inflammatory response syndrome occurs in patients with advanced cirrhosis and is associated with a bad prognosis.     

Predictive model of persistent choledocholithiasis in patients with acute biliary pancreatitis

BackgroundCholedocholithiasis causing acute biliary pancreatitis (ABP) may migrate to the duodenum or persist in the common bile duct (CBD). We developed a model for predicting persistent choledocholithiasis (PC) in patients with ABP.MethodsThis retrospective cohort study included 204 patients, age ≥18 years (mean age: 73 years, 65.7% women), admitted for ABP in 2013–2018, with at least a magnetic resonance cholangiopancreatography (MRCP), endoscopic ultrasonography (EUS), and/or endoscopic retrograde cholangiopancreatography (ERCP). Epidemiological, analytical, imaging, and endoscopic variables were compared between patients with and without PC. Multivariate logistic regression analyses were performed to develop a predictive model of PC.ResultsPatients underwent MRCP (n = 145, 71.1), MRCP and ERCP (n = 44, 21.56%), EUS and ERCP (n = 1, 0.49%), or ERCP (n = 14, 6.86%). PC was detected in 49 patients (24%). PC was strongly associated with CBD dilation, detected in the emergency ultrasound (p < 0.001; OR = 27; 95% CI: 5.8–185.5), increased blood levels of gamma glutamyl transpeptidase, detected at 72 h (p = 0.008; OR = 3.4; 95% CI: 1.5–8.9); and biliary sludge in the gallbladder (p = 0.008; OR = 0.03; 95% CI: 0.001–0.3).ConclusionsThe predictive model showed a validated area under the curve (AUC) of 0.858 for detecting PC in patients with ABP. A nomogram was developed based on model results.ConclusionsThe predictive model was highly effective in detecting PC in patients with ABP. Therefore, this model could be useful in clinical practice.     

Neutrophil,lymphocyte and platelet ratio as a predictor of mortality in septic-acute kidney injury patients

BackgroundAKI is frequent in critically ill patients, in whom the leading cause of AKI is sepsis. The role of intrarenal and systemic inflammation appears to be significant in the pathophysiology of septic-AKI. The neutrophils to lymphocytes and platelets (N/LP) ratio is an indirect marker of inflammation. The aim of this study was to evaluate the prognostic ability of N/LP ratio at admission in septic-AKI patients admitted to an intensive care unit (ICU).MethodsThis is a retrospective analysis of 399 septic-AKI patients admitted to the Division of Intensive Medicine of the Centro Hospitalar Universitário Lisboa Norte between January 2008 and December 2014. The Kidney Disease Improving Global Outcomes (KDIGO) classification was used to define AKI. N/LP ratio was calculated as: (Neutrophil count × 100)/(Lymphocyte count × Platelet count).ResultsFifty-two percent of patients were KDIGO stage 3, 25.8% KDIGO stage 2 and 22.3% KDIGO stage 1. A higher N/LP ratio was an independent predictor of increased risk of in-hospital mortality in septic-AKI patients regardless of KDIGO stage (31.59 ± 126.8 vs 13.66 ± 22.64, p = 0.028; unadjusted OR 1.01 (95% CI 1.00–1.02), p = 0.027; adjusted OR 1.01 (95% CI 1.00–1.02), p = 0.015). The AUC for mortality prediction in septic-AKI was of 0.565 (95% CI (0.515–0.615), p = 0.034).ConclusionsThe N/LP ratio at ICU admission was independently associated with in-hospital mortality in septic-AKI patients.     

Trichomonas vaginalis and associated factors among women living with HIV/AIDS in Amazonas,Brazil

ObjectivesOur goal was to determine the prevalence of Trichomonas vaginalis and its associated factors among women living with HIV attending an AIDS clinic in Manaus, Amazonas, Brazil.MethodsCross-sectional study among women attending an AIDS clinic in Manaus between March and December 2010 for gynecological examination were invited to participate. Enrolled patients answered a face-to-face interview including demographic, behavioral and clinical data. They also underwent a gynecological evaluation and cervical scrape samples were collected for wet mount, Gram stain, culture and cytological analysis. A blood sample was obtained to determine TCD4+ lymphocytes and viral load.ResultsA total of 341 (91.2%) women participated in the study. The prevalence of T. vaginalis was 4.1% (95% CI: 2.0–6.2%). Median age was 32 (interquartile range 27–38) years and median years of schooling was 9.0 (interquartile range 4–11). A total of 165 (53.2%) HIV women were classified as patients with AIDS. In multivariate analyses, squamous intraepithelial lesions in cytology [OR = 2.46 (95% CI: 1.31–4.63, p = 0.005)] and anal sex practice [OR = 3.62 (95% CI: 1.08–12.19, p = 0.037)] were associated with T. vaginalis.ConclusionsThese results highlight that HIV-infected women should be screened for T. vaginalis. The control of this infection may have an impact on preventing reproductive complications among these women.     

STEMI vs NSTEACS management trends in non-invasive hospital

ObjectivesTo compare the clinical features, management, and in-hospital outcomes of patients with ST elevation myocardial infarction (STEMI) and non-ST elevation acute coronary syndrome (NSTEACS), in the Western Region of Saudi Arabia.MethodsA total of 71 patients were enrolled in a longitudinal study at a tertiary hospital without cardiac catheterization facility. These data were collected from Saudi Project for Assessment of Coronary Events registry.ResultsTwenty-three patients with STEMI were compared to 48 patients with NSTEACS. Mean age for STEMI was younger, 57.4 ± 13.7 years compared to 63.2 ± 13.9 years respectively (p = 0.19). Forty-four percent arrived at the hospital by ambulance. History of hypertension and hyperlipidemia were more frequent in NSTEACS (p = 0.05), while both groups showed no difference in diabetes mellitus, 17% vs 22% and smoking, 30% vs 17%. In-hospital medications were: Aspirin (100%) both groups, Clopidogrel (91% vs 100%) (p = 0.03). There was more aggressive use of beta-blockers (74% vs 95%) (p = 0.01) and statins (87% vs 100%) (p = 0.01) in NSTEACS.In-hospital outcomes showed one recurrent myocardial infarction and one death in NSTEACS group (2%). Other outcome in the two groups showed recurrent ischemia (13% vs 29%) (p = 0.14) and cardiogenic shock (9% vs 2%) (p = 0.17). No stroke or major bleeding was reported in both groups.ConclusionNSTEACS patients in western province of KSA present at an older age are mostly males and have higher prevalence of hypertension and hyperlipidemia compared with STEMI patients. It is therefore important to identify patients with high-risk profile and put implement measures to reduce these factors.     

Facteurs de risque de mortalité hospitalière au cours de l’embolie pulmonaire en milieu de pneumologie

ObjectivesThe objective of our work is to identify the risk factors for hospital mortality during pulmonary embolism in a pneumology department.Material and methodAll patients admitted to the pneumology department of Habib-Bourguiba hospital between 2014 and 2019, with a final diagnosis of PE are analyzed.ResultsOne hundred patients were included, 62% of whom were female, with an average age of 63 ± 16 years. Pulmonary fibrosis was noted in eight patients. On admission, the mean Simplified Pulmonary Embolism Severity Index score was 1.46 ± 1.05. The mean duration of hospitalization was 10.6 ± 7 days. The hospital mortality rate was 12%. The independent risk factors for intra-hospital mortality were arterial hypotension (OR: 6.13; 95% CI: 2.88–14.35; p = 0.001), cancer (OR: 2.66; 95% CI: 1.22–9.54; p = 0.026), a VD/LV ratio at echocardiography > 0.9 (OR: 1.84; 95% CI: 1.06–7.69; p = 0.039) and severe hypoxemia (OR: 4.86; 95% CI: 2.19–11,34; p = 0.006).ConclusionPulmonary embolism mortality remains high despite improvements in diagnostic and therapeutic management. It is important for our country to take these results into consideration for a better management of patients admitted for pulmonary embolism, and to improve survival.     

Prevalence of mental disorder and impact on quality of life in inflammatory bowel disease

IntroductionDifferent studies have described psychiatric comorbidities in inflammatory bowel disease (IBD) patients, but most of them focus mainly on depression and anxiety. Even though major mental disorders are considered one of the main factors that decrease quality of life (QoL), its role in IBD patients remains unclear. We sought to identify the prevalence of different mental disorders as well as its relationship with QoL.Patients and methodsSubjects were recruited from the IBD Clinic. IBD Questionnaire 32 and structured clinical interview (SCID) for DMS-IV Text Revision were applied. Demographic and clinical data were collected via self-report questionnaires and medical records. The correlation between mental disorders and QoL (IBDQ-32 score) was evaluated using the Spearman correlation test.ResultsIn all, 104 patients were recruited, 12 with Crohn's disease, and 92 with ulcerative colitis. The prevalence of any major mental disorder was 56.7%: anxiety (44.2%), mood (27.9%), substance use (12.2%), and other psychiatric diagnoses (17.3%), and 29.8% of the patients presented three or more comorbid diagnoses. Mental Disorder (p = 0.005), mood disorder (p = 0.004), anxiety disorder (p = 0.009), were found to be significantly associated with lower QoL. Substance use disorder was associated with lower Digestive QoL (p = 0.01). Major depressive disorder (p = 0.004), social phobia (p = 0.03), PTSD (p = 0.02), and Generalized Anxiety Disorder (p < 0.001), were found to be significantly associated with lower QoL.ConclusionsIBD patients had important psychiatric comorbidity that significantly affects their QoL. These results warrant a systematic evaluation of psychiatric conditions in IBD patients.     

Increased HIV infection in patients with stroke in Spain. A 16-year population-based study

IntroductionAn increased incidence of stroke in HIV-infected patients has already been reported, suggesting that HIV infection may be a cerebrovascular risk factor. The objective of this study was to assess temporal trends in the proportion of HIV infection among patients with stroke in Spain.MethodsData were obtained from the minimum basic dataset (MBDS) of all patients hospitalized in Spain between 1997 and 2012 with a primary or secondary diagnosis of stroke. The annual proportion of HIV infection and time trends (stratifying by type of stroke and HIV stage) were calculated, and predictors of HIV infection and the social and economic impact of HIV-infected (HIV+) and non-infected (HIV−) patients were analyzed.ResultsOf 857,371 patients hospitalized with an incident stroke, 2134 (0.25%) had HIV infection. A 2.5% year-on-year increase (OR 1.025, 95% CI 1.015–1.036, p < 0.0001) of the proportion of HIV-infected patients was observed due to an increase in the asymptomatic stage of the infection (per year OR 1.077, 95% CI 1.057–1.097, p < 0.0001), as the proportion of patients with AIDS remained stable. Factors independently associated with HIV infection and stroke were active smoking, stimulating drugs and hepatitis C virus (HCV) infection. A higher mortality rate, longer hospital stay and a higher cost per hospitalized patient was observed among HIV+ patients.ConclusionsFrom 1997 to 2012, there was an increase in the proportion of HIV infection among patients hospitalized with stroke irrespective of the classical vascular risk factors, reinforcing the role of HIV infection as a cerebrovascular risk factor.     

Comparison of urgent and early endoscopy for acute non-variceal upper gastrointestinal bleeding in high-risk patients

ObjectiveData regarding early (within 24 h) and urgent endoscopy (within 12 h) in non-variceal upper gastrointestinal bleeding (NV-UGIB) revealed conflicting results. This study aimed to investigate the impact of endoscopy timing on the outcomes of high-risk patients with NV-UGIB.Patients and methodsFrom February 2020 to February 2021, consecutive high-risk (Glasgow–Blatchford score ≥12) adults admitted to the emergency department with NV-UGIB were analyzed retrospectively. The primary composite outcome was 30-day mortality from any cause, inpatient rebleeding, need for endoscopic re-intervention, need for surgery or angiographic embolization.Results240 patients were enrolled: 152 (63%) patients underwent urgent endoscopy (<12 h) and 88 (37%) patients underwent early endoscopy (12–24 h). One or more components of the composite outcome were observed in 53 (22.1%) patients: 30 (12.5%) had 30-day mortality, rebleeding occurred in 27 (11.3%), 7 (2.9%) underwent endoscopic re-intervention, and 5 (2.1%) required surgery or angiographic embolization. The composite outcome was similar between the groups. Multivariate analysis showed only hemodynamic instability on admission (OR: 3.05, p = 0.006), and the previous history of cancer (OR: 2.42, p = 0.029) were significant in predicting composite outcome. In terms of secondary outcomes, the endoscopic intervention was higher in the urgent endoscopy group (p = 0.006), whereas the number of transfused erythrocyte suspensions and the length of hospital stay was higher in the early endoscopy group (p = 0.002 and p = 0.040, respectively).ConclusionsUrgent endoscopy leads to a significant reduction in the length of hospitalization and the number of transfused erythrocyte suspensions in NV-UGIB, which can contribute to patient satisfaction, reduce healthcare expenditure, and improve hospital bed availability. The composite outcome and its sub-outcomes were the same among both groups.     

The burden of inpatient costs in inflammatory bowel disease and opportunities to optimize care: A single metropolitan Australian center experience

Background and aimsInflammatory bowel disease (IBD) causes significant morbidity, frequently resulting in hospital admission and resection surgery. However, little is known about: 1. how IBD patients' inpatient healthcare utilisation compares to other inpatients and 2. whether there are potentially modifiable factors which may influence this.MethodsOver five months a cohort of admitted IBD patients were acquired and each assigned five admitted, age and gender matched controls at a single tertiary center. Data compared over 15 months included: total cumulative length of stay (TLoS), number of admissions (index and subsequent re-admissions), inpatient costs, care complexity (defined by relative stay index [RSI]), and disease-specific factors amongst the IBD cohort. Data were confirmed by case notes review.ResultsThere were 102 IBD patients and 510 controls (median age 44 years, 57% female). IBD patients had more re-admissions (mean 1.72 vs 1.55, p = 0.002) and longer TLoS (median 6.8 vs 3.4 days, p < 0.0001) than controls. Both median cumulative cost of inpatient healthcare and RSI were also higher in IBD compared to controls ($7052 vs $5470 and RSI 362% vs 293%, each p < 0.008). IBD patients seen by a gastroenterologist prior to their index admission had fewer re-admissions (mean 1.37 vs 2.02, p = 0.016,) and tended to have lower total cumulative inpatient costs than those without prior Gastroenterologist review (median $6439 vs $9479, p = 0.069).ConclusionsIBD patients have significantly greater inpatient healthcare utilization, complexity and costs than age and gender matched, hospitalized controls. Prior gastroenterologist care in IBD may reduce subsequent admission rates, and inpatient-related costs.     

Insulin resistance as a risk factor for subclinical atherosclerosis in rheumatoid arthritis

BackgroundInsulin resistance (IR) is strongly associated with systemic inflammation. Insulin resistance is known to be increased in patients with rheumatoid arthritis (RA) and has been shown to be a risk factor for both clinical cardiovascular disease and subclinical atherosclerosis.Aim of the workTo study the relationship between insulin resistance, disease activity and subclinical atherosclerosis in RA patients.Patients and methodsForty RA patients and twenty age and sex matched healthy individuals as controls were included. Patients with diabetes mellitus, obesity and hypertension were excluded. Fasting plasma sugar and serum insulin were done, RA disease activity was assessed using the disease activity score (DAS28) and IR was evaluated by the homeostasis model assessment (HOMA2). Carotid artery intima media thickness (IMT) was evaluated using ultrasound.ResultsRA patients had significantly higher erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) positivity, fasting plasma sugar and fasting serum insulin, HOMA2-IR levels than the controls. IR was present in 33 (82.5%) RA patients while it was present in only one (10%) of the controls (p = 0.001). RA patients with IR had significantly longer disease duration (p = 0.003), higher disease activity (p = 0.000), greater carotid IMT (p = 0.000), and more carotid plaques (p = 0.043) than those without insulin resistance. RA patients with increased IMT had significantly longer disease duration (p = 0.002), higher DAS28 score (p = 0.000) and higher HOMA2-IR (p = 0.000) than those with normal IMT.ConclusionsIn RA patients, IR significantly correlated with both disease activity and disease duration. Our study pointed out a significant association between IR and subclinical atherosclerosis in RA.     

Effects of sustained-release trimetazidine on chronically dysfunctional myocardium of ischemic dilated cardiomyopathy – Six months follow-up result

BackgroundIschemic cardiomyopathy is a growing burden in third world countries. So far, benefits of trimetazidine in this group of patients have been suggested by clinical trials mainly conducted in Europe. We evaluated the effect of trimetazidine on ischemic dilated cardiomyopathy in our population.Methods and results98 patients (aged 58.5 ± 9.2 years), admitted with decompensated heart failure with previous history of MI and/or documentation of significant CAD with previous CAG, were chosen for the study. Patients were randomized into two groups – one provided with trimetazidine 35 mg sustained released tablet, twice daily and the other with a placebo, along with other conventional medications. Patients were included if they had dilated LV (LVIDd > 57 mm) and left ventricular ejection fraction (LVEF) ≤40%. After 6 months, significantly higher number of patients in trimetazidine group were in NYHA class I (22% vs. 8%, p = 0.03) and class II (56% vs. 34%, p = 0.01); higher number of patients in placebo group were in NYHA class III class IV. Anginal episodes and use of sublingual nitrate per week were significantly lower in the trimetazidine group. Left ventricular diastolic dimension (59.7 ± 5.2 vs. 65.1 ± 6.1, p = 0.001) was significantly different in the two groups as was the increase of LVEF (11% vs. 5.6%, p = 0.001). Hospitalization for worsening heart failure was significantly lower in trimetazidine group (13 vs. 22, p = 0.047).ConclusionTrimetazidine seems to be beneficial in patients with ischemic dilated cardiomyopathy in South Asian population and larger scale study with extended follow-up is needed.     

HLA-DRB1 alleles in Egyptian rheumatoid arthritis patients: Relations to anti-cyclic citrullinated peptide antibodies,disease activity and severity

BackgroundHuman leukocyte antigen HLA-DRB1 alleles encoding a common amino acid sequence called shared epitope in the third hypervariable region of DRB1 molecule have been identified as risk alleles for rheumatoid arthritis (RA).Aim of the workThe aim was to study HLA-DRB1 01, 04 and 10 alleles in Egyptian RA patients and determine their relation with anticyclic citrullinated peptide (anti-CCP) antibody level, disease activity, clinical and radiological severity.Patients and methodsThe study involved 40 RA patients and 20 control. Simplified disease activity index (SDAI) was calculated, clinical severity was assessed using the mechanical joint score (MJS) and radiological severity evaluated using the simple erosion narrowing score (SENS). HLA-DRB1 genotyping and anti-CCP antibodies were detected.ResultsThe mean patients’ age was 41.6 ± 12.7 years and disease duration 8.9 ± 7.7 years. The frequency of HLA DRB1 01, 04 and 10 in patients was 42.5%, 60% and 25% respectively. Of them 04 was significantly higher than in controls (p = 0.013) and was associated with anti-CCP positive cases (p = 0.0008) while the absence of HLA-DRB1 alleles was significantly associated with negative anti-CCP negative RA (p = 0.0008). There were significant associations between HLA-DRB1 01 and 04 with SDAI (p = 0.0002 and p = 0.005, respectively); between HLA-DRB1 04 and 10 with SENS (p = 0.002 and p = 0.001 respectively) and between HLA-DRB1 01, 04 and 10 with MJS (p = 0.02, p = 0.03 and p = 0.02, respectively).ConclusionHLA-DRB1 04 is associated with RA in Egyptian patients and is strongly associated in the production of elevated titers of anti-CCP antibodies which contribute to the development, severity and activity of the disease.
