Background:Gout is the most common inflammatory arthritis resulting from a chronic deposition of MSU crystals in the joints and other soft tissues. After the process of repeated tissue damage and repair due to gout, tophi could be formed around the affected joints. Intra-articular tophi may sometimes result in bone destruction, joint deformities, and dysfunction which can adversely affect the patient’s quality of life. Furthermore, early-onset tophaceous gout patients are more likely to develop renal dysfunction, however, few studies have investigated if the presence of tophi is related with the progression of renal dysfunction in gout patients.Objectives:We aimed to compare clinical characteristics of patients with and without tophi at the time of the diagnosis of gout and investigate the effect of tophi on the renal function in gout patients.Methods:Data of 257 patients who were first diagnosed with gout at the Kangwon National University Hospital from January 2012 to December 2018 were retrospectively studied. Patients were divided into 2 groups according to the presence of tophi at the diagnosis. We compared clinical characteristics and the progression of renal dysfunction between the two groups.Results:Of all patients, 66 (25.5%) initially presented with tophi. Patients with tophi were older, had a longer duration of symptoms, and had a higher prevalence of multiple joint involvement than those without tophi. The decline in the eGFR was more prominent in patients with tophi than in those without (-4.8±14.5 ml/min/1.73m2vs. -0.7±11.9 ml/min/1.73m2, respectively; P=0.039). In multivariate logistic regression analysis, a prolonged symptom duration (odds ratio [OR], 1.010; 95% confidence interval [CI], 1.004–1.017; P=0.001) and multiple joint involvement (OR, 3.027; 95% CI, 1.831–5.004; P<0.001) were significantly associated with increased risk of formation of tophi. The presence of tophi was significantly associated with a rapid decline in the eGFR (β=-0.141; P=0.035).Conclusion:A prolonged symptom duration and multiple joint involvement were independent risk factors for tophi as the presenting symptom in gout patients. The presence of tophi was associated with a declining renal function. Therefore, an early diagnosis and active treatment are important in tophaceous gout.References:[1]Bardin T, Richette P.

AbstractWe aimed to compare clinical characteristics of patients with and without tophi at the time of the diagnosis of gout and investigate the association of tophi and renal function in gout patients. The patients who were first diagnosed with gout at the Kangwon National University Hospital were retrospectively studied. Patients were divided into 2 groups according to the presence of tophi at the diagnosis. We compared clinical characteristics and the progression of renal dysfunction between the two groups. Of 276 patients, 66 (25.5%) initially presented with tophi. Tophi group was older, had a longer symptom duration, and a higher prevalence of multiple joint involvement than those without tophi. In multivariate logistic regression analysis, prolonged symptom duration and multiple joint involvement were significantly associated with increased risk of formation of tophi. The decline in the eGFR was more prominent in patients with tophi than in those without (− 4.8 ± 14.5 vs. − 0.7 ± 11.9 ml/min/1.73 m2/year, respectively; P = 0.039). The presence of tophi was significantly associated with a rapid decline in the eGFR (β = − 0.136; P = 0.042). In conclusion, the presence of tophi was associated with a rapid declining renal function. Therefore, an early diagnosis and closely monitoring of renal function might be important in gout patients with tophi.

Background:The incidence of juvenile gout is increasing in China. The clinical manifestations of juvenile gout and treatment strategies to reduce uric acid levels in children are not well described due to the limited number of cases in the past.Objectives:We aim to describe the clinical characteristic of children with gout and study the treatment response to febuxostat.Methods:These studies were approved by the Institutional Review Board of Guangdong Second provincial General Hospital. We performed a retrospective analysis on 98 juvenile gout patients (age ≤ 18 years) evaluated in our hospital from Jan 2016 to Dec 2019. We analyzed clinical parameters, laboratory data and treatment response.Results:The average age of disease onset in children with gout was 15.2 ± 2.0 years and the youngest patient was 9 years old. The majority of patients were male (94/98) and mean serum uric acid (sUA) level were 705.8 ± 145.7 μmol/L (reference range <420 μmol/L). More than half of the cohort had normal body mass index (mean 24.7 ± 4.7 kg/m2; range 14.9 to 36.1 kg/m2). Renal function was generally normal in these children (serum creatinine 96.9 ± 17.8 μmol/L). In terms of joint manifestations, juvenile gout preferentially affected finger joints (29%), ankles (28%) and metatarsal joints (MTP; 20%). The most frequent sites of initial gout attack were ankles (45%), MTP (39%) and fingers (6%). In addition, tophi can occur in pediatric patients and typically develop in the finger joints (54%). Tophi was observed in about 25% of juvenile gout patients, typically within the first two years of disease onset (mean duration 1.7 ± 0. 9 years). We have found tophi in children as young as 10 years of age.For treatment for chronic hyperuricemia, 32 patients (32.7%) were started on febuxostat and 5 patients (5.1%) received allopurinol. A decrease in sUA was observed in both groups after the first month of treatment (febuxostat: baseline 690.4 ± 99.7 μmol/L to 482.7 ± 140.8 μmol/L vs. allopurinol: baseline 728.8 ±112.8 μmol/L to 565.0 ± 116.7 μmol/L, P=0.477). Serum uric acid of 6 patients in the febuxostat group (none in the allopurinol group) dropped below 360 μmol/L. There were no statistical differences in Cr, AST and ALT between the groups. During follow-up after 3 months, further decline in sUA level were observed in patients treated with febuxostat (409.5 ± 83.4, compared with baseline P<0.001).Conclusion:Juvenile gout has a different pattern of joint involvement and is less associated with elevated BMI compared to gout in adults. We show that febuxostat is effective in reducing uric acid levels in juvenile gout. These findings will help clinicians better understand the clinical manifestations and treatment response in juvenile gout.Figure 1Compared treatment response with allopurinol and febuxostatReferences:[1]Kishimoto K, Kobayashi R, Hori D, et al.

Abstract To provide descriptive data on injury presentation and treatment and to identify risk factors for requiring surgical treatment for athletes presenting with CrossFit-related hip and groin injuries. CrossFit-related injuries (n = 982) were identified within a single hospital system from 2010 to 2017, with 83 (8.5% of total) identified hip or groin injuries. Patient demographics, injury diagnosis, surgical procedure and rehabilitation were assessed. Independent predictors of requiring surgery were analyzed via multivariate logistic regression analysis. Patients with hip or groin injuries were more often female (hip injuries: 63%; all injuries: 50%; P &lt; 0.001) with mean age 34.3 years (standard deviation 10.9). Median symptom duration was 4 months with 70% reporting insidious onset. Most common diagnoses were femoral-acetabular impingement syndrome (34%), hamstring strain (11%), non-specific hip/groin pain (imaging non-diagnostic) (11%), hernia (7%) and iliotibial band syndrome (6%). Most (90%) required physical therapy (median 2 months). Surgery occurred in 24% (n = 12 hip arthroscopy, n = 5 inguinal hernia repair, n = 3 total hip arthroplasty), with 100% return to sport after arthroscopy or hernia repair. The only predictor of surgery was complaint of primarily anterior hip/groin pain (82% surgical patients, 46% non-surgical) (odds ratio 5.78, 95% confidence interval 1.44–23.1; P = 0.005); age, sex, body mass index, symptom duration and symptom onset (insidious versus acute) were non-significant (P &gt; 0.25). CrossFit athletes with hip and groin injuries often present with prolonged symptoms with insidious onset. Most patients require several months of physical therapy and approximately one quarter require surgery. Patients presenting with primarily anterior hip/groin pain are at increased risk for requiring surgery. Level of Evidence IV, case series.

Objective.Age of onset of gout has recently decreased; however, patients with early-onset gout remain uncommon, and relevant information is scant. We hypothesized that these patients might exhibit differences in serum urates and other comorbidities compared with adult-onset patients.Methods.Early-onset gout patients (i.e., juveniles) with (n = 40) and without tophi (n = 47) were enrolled for study. Their clinical characteristics were compared with those of 353 patients with middle-age-onset tophaceous gout and 64 age-matched healthy participants.Results.Early-onset gout patients with tophi exhibited significantly higher body mass indices and serum urate levels and lower estimated glomerular filtration rates (eGFR) than did those without tophi. Early-onset gout patients with or without tophi demonstrated significantly abnormal lipid profiles and impaired liver or renal function compared with healthy patients. Serum urate levels and gout duration were identified as the principal determinants of tophi development. The presence of tophi might be crucial in decreasing eGFR, which is inversely related to tophi duration or gout duration. Unexpectedly, the most common site of initial gout attacks in early-onset tophaceous gout patients was the ankle, not the toe, which was the most common site in middle-age-onset tophaceous gout patients. The most common site of first tophi occurrence in early-onset patients was a finger, not a toe, which was the most common site in middle-age-onset patients.Conclusion.Early-onset tophaceous gout patients are more likely to exhibit comorbidities and renal dysfunction than middle-age-onset patients and exhibit distinct first sites of gout attack and tophi occurrence patterns.

(1) Our study aimed to look at the clinical characteristics, treatment and short-term outcomes of patients hospitalized due to heart failure with coexisting cancer. (2) Methods: Seventy one cancer (Ca) patients and a randomly selected 70 patients without Ca, hospitalized due to heart failure exacerbation in the same time period constituted the study group (Ca patient group) and controls (non-Ca group), respectively. Data on clinical characteristics were collected retrospectively for both groups. (3) Results: Cancer patients presented with a less advanced NYHA class, had more frequent HFpEF, a higher peak troponin T level, and smaller left atrium size, as compared with controls. The in-hospital deaths of Ca patients were associated with: a higher New York Heart Association (NYHA) class, lower HgB level, worse renal function, higher K and AST levels, presence of diabetes mellitus, and HFpEF. By multivariate logistic regression analysis, impaired renal function was the only independent predictor of in-hospital death in Ca patients (OR-1.15; CI 1.05; 1.27); p = 0.017). The following covariates entered the regression: NYHA class, HgB, GFR, K+, AST, diabetes mellitus t.2, and HFpEF. (4) Conclusions: The clinical picture and the course of heart failure in patients with and without cancer are different.

Abstract Background: Differences in the clinical features and outcomes between syncytial virus-related (RSV-p) and influenza-related pneumonia (Flu-p) are largely unknown. We aimed to compare clinical characteristics and severity between adults with the two conditions . Methods: A total of 127 patients with RSV-p, 693 patients with influenza A-related pneumonia (FluA-p) and 386 patients with influenza B-related pneumonia (FluB-p) were retrospectively reviewed from 2013 through 2019 in five teaching hospitals in China. Results: A multivariate logistic regression model indicated that age ≥ 50 years, cerebrovascular disease, chronic kidney disease, solid malignant tumor, nasal congestion, myalgia, sputum production, respiratory rates ≥ 30 beats/min, lymphocytes < 0.8×109/L and blood albumin < 35 g/L were predictors that differentiated RSV-p from Flu-p. After adjusting for confounders, a multivariate logistic regression analysis confirmed that, relative to RSV-p, FluA-p (OR 2.313 , 95% CI 1.377 - 3.885, p = 0.002) incurred an increased risk for severe outcomes, including invasive ventilation, ICU admission, and 30-day mortality. FluB-p (OR 1.630 , 95% CI 0.958 - 2.741, p = 0.071) was not associated with increased risk. Conclusions: The severity of RSV-p was less than that of FluA-p, but was comparable to FluB-p. Some clinical variables were useful for discriminating RSV-p from Flu-p.

Atrial fibrillation and renal dysfunction often coexist, each disorder may predispose to the other and contribute to worsening prognosis. Both atrial fibrillation and chronic kidney disease are associated with increased risk of stroke and thromboembolic complications. Oral anticoagulation for stroke prevention is therefore recommended in patients with atrial fibrillation and decreased renal function. Each direct oral anticoagulant has unique pharmacologic properties of which clinician should be aware to optimally manage patients. The doses of direct oral anticoagulants require adjustment for renal function. There is debate regarding which equation, the Chronic Kidney Disease Epidemiology (CKD-EPI) equation vs. the Cockcroft-Gault equation, should be used to estimate glomerular filtration rate in patients with atrial fibrillation treated with direct oral anticoagulants. Our review tries to find arguments for benefit of direct oral anticoagulants in patients with renal dysfunction.

Background/Aim: Recently, it was reported that the use of androgen deprivation therapy (ADT) is significantly associated with an increased risk of acute kidney injury (AKI) in patients with newly diagnosed non-metastatic prostate cancer. This study aimed to investigate the incidence of early renal dysfunction in Japanese prostate cancer patients receiving ADT and the factors associated with it. Patients and Methods: A total of 135 patients who had been pathologically diagnosed with prostate cancer and had received ADT for at least 6 months were eligible for study inclusion. The estimated glomerular filtration rate (eGFR) before treatment, and at 1, 3, and 6 months of ADT were evaluated retrospectively. We assessed renal function using eGFR and investigated the rate of change in the eGFR (ΔeGFR) during ADT. Univariate and multivariate logistic analyses were carried out to identify clinical factors that were significantly associated with renal dysfunction after 6 months ADT. Results: A total of 110 cases were evaluated in this study. The incidence of renal dysfunction after 6 months ADT was 63% (69/110). The mean ΔeGFR after 1, 3, and 6 months of ADT were –0.6%, –3.1% and –1.7%, respectively (p<0.001). Multivariate analysis showed that renal dysfunction after 3 months of ADT and hypertension were independent risk factors for renal dysfunction after 6 months ADT. Conclusion: Renal dysfunction occurs from 1 month of ADT and hypertensive prostate cancer patients receiving ADT are at high risk of developing renal dysfunction, and that such patients should be treated very carefully. Therefore, patients that are started on ADT should undergo periodic prostate-specific antigen, renal function, and urinary salt intake examinations.

The survival advantage observed among peritoneal dialysis patients early on after dialysis initiation has been largely attributed to residual renal function (RRF) preservation due to higher baseline residual function and fewer comorbidities. We hypothesize that a rapid decline in RRF is associated with higher risk of anuria and mortality. In a retrospective cohort study of 581 subjects on peritoneal dialysis with longitudinal prevalent data, we assessed whether RRF change over time, in addition to baseline RRF, increased risk of mortality and anuria using Kaplan-Meier analysis and Cox proportional hazard analysis to control for known risk factors. Rapid RRF decline (≥ 0.09 decline) over a 12-month period was associated with a 2.6-fold increase in the risk of death (hazard ratio [HR] 2.60, 95% confidence interval [CI] 1.66 – 4.07, compared with < 0.09 decline) and a 2-fold increase in anuria (HR 2.06, 95% CI 1.24 – 3.42). Each quartile of increasing severity of RRF decline over a 12-month period increased risk incrementally for death (2ndquartile: HR 3.04, CI 1.26 – 7.34; 3rdquartile: HR 4.01, CI 1.71 – 9.83; 4thquartile HR 5.78, CI 2.10 – 15.9) and generally for anuria (quartiles with HR 5.72 – 7.21). The escalating risk of mortality and anuria was greater for those with diabetes mellitus. In conclusion, rapid decline in RRF over a 12-month period increased the risk of mortality and likewise anuria, beyond previously established risk factors for mortality and anuria. The impact on mortality and RRF preservation was particularly severe for those with diabetes mellitus.

Introduction: Acute pyelonephritis (APN) is a common infection during pregnancy that increases the risk of unfavorable maternal and fetal outcomes. However, it has not been clearly elucidated which demographic and clinical characteristics are associated with the incidence of APN during pregnancy. Objective: This population-based cohort study aimed to determine the risk factors for APN during pregnancy. Methods: Using the database of the Health Insurance Review and Assessment Service of South Korea, we enrolled Korean women who delivered infants between 2010 and 2014 in Korea and had complete health examination records within 1 year of pregnancy. We performed multivariate logistic regression analysis to evaluate the risk factors for APN during pregnancy. Results: Of 370,248 women, 2,526 (0.7% of the total participants) were treated for APN while in hospitalization during pregnancy. Younger age, history of previous APN within 1 year of pregnancy, and abnormal results of health examination before pregnancy, such as high fasting glucose level (>100 mg/dL) and proteinuria, were associated with an increased risk of APN during pregnancy. Conclusion: Certain maternal demographic and clinical characteristics were associated with the incidence of APN during pregnancy, and these should be monitored closely during antenatal care.
