ABSTRACT

Effective management of gout includes the following: appropriate control of gout flares; lifestyle modifications; management of comorbidities; and long-term urate-lowering therapy (ULT) to prevent subsequent gout flares, structural joint damage, and shortening of life expectancy. In addition to traditional treatments for gout, novel therapies have been introduced in recent years. Indeed, new recommendations for the management of gout have been proposed by various international societies. Although effective and safe medications to treat gout have been available, management of the disease has continued to be suboptimal, with poor patient adherence to ULT and failure to reach serum urate target. This review outlines recent progress in gout management, mainly based on the latest published guidelines, and specifically provides an update on efficient strategies for implementing treatment, efficacy and safety of specific medications for gout, and cardiovascular outcomes of ULT. In particular, we reviewed gout management approaches that can be applied to a Korean population.

ABSTRACT

Purpose@#In June 2016, the Model for End-Stage Liver Disease (MELD) score was employed in South Korea instead of the Child-Turcotte-Pugh (CTP) score. This study compared the outcomes of deceased donor liver transplantation (DDLT) before and after the MELD system application. @*Methods@#This retrospective study reviewed 48 patients who underwent DDLT for end-stage liver disease at a single tertiary referral center between January 2014 and December 2018. The patients were categorized into the pre-MELD (22 patients) and post-MELD (26 patients) groups. The demographics, postoperative outcomes, and overall survival time were evaluated between the 2 groups. @*Results@#The 2 groups had no differences in age, sex, ABO type, etiology for liver transplantation, CTP-score, operation time, cold ischemic time, and amount of red blood cell transfusion, although their MELD score differed significantly (postMELD group, 36.2 ± 4.9; pre-MELD group, 27.7 ± 11.8; P < 0.001). The post-MELD group has longer intensive care unit stay (11.2 ± 9.5 days vs. 5.7 ± 4.5 days, P = 0.018) and hospital stay than the pre-MELD group (36.8 ± 26 days vs. 22.8 ± 9.3 days, P = 0.016). The 1-year survival rate was lower in the post-MELD group (61.5% vs. 86.4%, P = 0.029). @*Conclusion@#After MELD allocation, patients with high MELD scores had increased DDLT and consequently required a longer recovery time, which could negatively affect survival. According to the experience of a small-volume center, these problems were related to both severe organ shortages in South Korea and MELD allocation.

ABSTRACT

Purpose@#Intensive care unit (ICU) bed availability is key to critical patient care. In many countries, older patients generally account for a significant proportion of hospitalizations and ICU admissions. Therefore, considering the rapidly increasing aging population in South Korea, it is important to establish whether the demand for critical care is currently met by available ICU beds. @*Materials and Methods@#We evaluated a 9-year trend in ICU bed supply and ICU length of stay in South Korea between 2011 and 2019 in a population-based cross-sectional analysis, using data from the Korean Health Insurance Review & Assessment Service and Statistics database. We described the changes in ICU bed rates in adult (≥20 years) and older adult (≥65 years) populations. ICU length of stay was categorized similarly and was used to predict future ICU bed demands. @*Results@#The ICU bed rate per 100000 adults increased from 18.5 in 2011 to 19.5 in 2019. In contrast, the ICU bed rate per 100000 older adults decreased from 127.6 in 2011 to 104.0 in 2019. ICU length of stay increased by 43.8% for adults and 55.6% for older adults. In 2019, the regional differences in the ICU bed rate nearly doubled, and the ICU length of stay increased six-fold. The ICU bed occupancy rate in South Korea is expected to rise to 102.7% in 2030. @*Conclusion@#The discrepancy between the demand and supply of ICU beds in South Korea requires urgent action to anticipate future ICU demands.

ABSTRACT

Background@#Patient-centered management is becoming increasingly important in gout, but there are limited studies exploring patients' perspectives and preferences. We aimed to investigate patients' perspectives and preferences regarding gout and gout management, and their impacts on adherence to urate lowering therapy (ULT). @*Methods@#A paper-based survey was performed in patients with gout seen at the rheumatology outpatient clinics of 16 tertiary hospitals. The survey included questions regarding demographics, comorbidities, gout attacks, current treatment and adherence, and patients' perspectives and preferences regarding gout and gout management. Multivariate regression analysis was performed to determine the factors associated with ULT adherence. @*Results@#Of 809 surveyed patients with gout, 755 (94.5%) were using ULT. Among those using ULT, 89.1% had ≥ 80% adherence to ULT. Majority of the patients knew management strategies to some extent (94.8%), perceived gout as a life-long disease (91.2%), and were making efforts toward practicing at least one lifestyle modification (89.2%). Most patients (71.9%) obtained information about gout management during their clinic visits.Approximately half of the patients (53.6%) preferred managing their disease with both ULT and lifestyle modification, 28.4% preferred ULT only, and 17.4% preferred lifestyle modification only. Adherence was better in patients with older age (odds ratio [OR], 1.03), those with better knowledge of gout management strategies (OR, 3.56), and those who had preference for ULT (OR, 2.07). @*Conclusion@#Patients' perspectives and management preferences had high impacts on adherence to ULT in gout. Consideration of patients' perspectives and preferences is important for achieving the desired clinical outcome in gout.

ABSTRACT

Background@#The 24-hour uric acid excretion measurement is important in assessing disease status and helping to select the appropriate uric acid-lowering agent for patients with gout, however, it is inconvenient. The authors investigated the efficacy of the random urine uric acid-to-creatinine (UA/CR) ratio to screen the patients who under-secreted 24-hour urine uric acid. @*Methods@#This was a retrospective cross-sectional study. Ninety patients with gout, without undergoing uric acid-lowering treatment were enrolled. Twenty-four-hour urine and random urine samples were obtained on the same day. Six hundred mg of uric acid in the 24-hour urine sample was used as a standard for distinguishing between over and under-excretion groups. @*Results@#The random urinary UA/CR ratio showed positive correlation with 24-hour urine uric acid excretion (γ = 0.398, P < 0.001). All the patients with the random UA/CR less than 0.2 excreted less than 600 mg uric acid in 24-hour urine collection. When the random urine UA/CR ratio < 0.2 was regarded as a positive result, the positive predictive value, negative predictive value, sensitivity, and specificity in the uric acid under-excretion were 100% (8 of 8), 64.6% (53 of 82), 21.6% (8 of 37), and 100% (53 of 53), respectively. @*Conclusion@#There is a moderate positive correlation between the random urinary UA/CR ratio and 24-hour urine uric acid excretion, so that UA/CR ratio may not be a good predictor of 24-hour urine uric acid excretion. However, the random urine UA/CR ratio 0.2 can be a useful predictor to screen the gouty patients who need to be treated with uricosuric drugs.

ABSTRACT

Background@#We purposed to evaluate the seasonality and associated factors of the incidence of gout attacks in Korea. @*Methods@#We prospectively enrolled patients with gout attacks who were treated at nine rheumatology clinics between January 2015 and July 2018 and followed them for 1-year. Demographic data, clinical and laboratory features, and meteorological data including seasonality were collected. @*Results@#Two hundred-five patients (men, 94.1%) were enrolled. The proportion of patients with initial gout attacks was 46.8% (n = 96). The median age, body mass index, attack duration, and serum uric acid level at enrollment were 50.0 years, 25.4, 5.0 days, and 7.4 mg/dL, respectively. Gout attacks were most common during spring (43.4%, P < 0.001) and in March (23.4%, P < 0.001). A similar pattern of seasonality was observed in the group with initial gout attacks. Alcohol was the most common provoking factor (39.0%), particularly during summer (50.0%). The median diurnal temperature change on the day of the attack was highest in the spring (9.8°C), followed by winter (9.3°C), fall (8.6°C), and summer (7.1°C) (P = 0.027). The median change in humidity between the 2 consecutive days (the day before and the day of the attack) was significantly different among the seasons (3.0%, spring; 0.3%, summer; −0.9%, fall; −1.2%, winter; P = 0.015). One hundred twenty-five (61%) patients completed 1-year follow-up (51% in the initial attack group). During the follow-up period, 64 gout flares developed (21 in the initial attack group). No significant seasonal variation in the follow-up flares was found. @*Conclusion@#In this prospective study, the most common season and month of gout attacks in Korea are spring and March, respectively. Alcohol is the most common provoking factor, particularly during summer. Diurnal temperature changes on the day of the attack and humidity changes from the day before the attack to the day of the attack are associated with gout attack in our cohort.

ABSTRACT

Objectives@#Osteoporosis and fracture are known complications of systemic lupus erythematosus (SLE). We assessed the prevalence and risk factors for osteoporosis in patients with SLE. @*Methods@#A total of 155 female SLE patients were recruited retrospectively in 5 university hospitals. The bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry, and the fracture risk assessment tool (FRAX) for high-risk osteoporotic fractures was calculated with and without BMD. @*Results@#The mean age was 53.7 ± 6.8 years, and osteoporotic fractures were detected in 19/127 (15.0%) patients. The proportion of patients having a high-risk for osteoporotic fractures in the FRAX with and without BMD, and osteoporosis by the World Health Organization (WHO) criteria were 25 (16.1%), 24 (15.5%), and 51 (32.9%), respectively, and 48.0–68.6% of them were receiving treatment. On multivariate logistic analysis, nephritis (odds ratio [OR] 11.35) and cumulative dose of glucocorticoid (OR 1.1) were associated with high-risk by the FRAX with BMD, and low complement levels (OR 4.38), erythrocyte sedimentation rate (ESR) (OR 1.04), and cumulative dose of glucocorticoid (OR 1.05) were associated with osteoporosis by the WHO criteria in patients with SLE. @*Conclusions@#Among Korean female patients with SLE, the proportion of patients having a high-risk of osteoporotic fractures by the FRAX tool was 15.5%–16.1% and the proportion of patients having osteoporosis by the WHO criteria was 32.9%. In SLE, nephritis, low level of complement, ESR, and cumulative dose of glucocorticoids may contribute to fracture risk.

ABSTRACT

BACKGROUND: Both hyperuricemia and hyperhomocysteinemia are known as main risk factors of cardiovascular diseases. There has been, however, no report on the relationship between carotid intima-media thickness (IMT) and homocysteine (Hcy) in hyperuricemic patients. This study aimed to investigate how hyperuricemia is associated with increased carotid IMT with a focus on hyperhomocysteinemia. METHODS: This cross-sectional study included 1,222 patients who visited the Chung-Ang University Hospital Health Promotion Center from January 2013 to December 2015. The serum Hcy levels were estimated with a competitive immunoassay using the direct chemiluminescence method. The carotid IMT was measured by B-mode carotid ultrasonography. The definition of hyperuricemia was a serum uric acid level > 7.0 mg/dL for men or > 5.6 mg/dL for women, and hyperhomocysteinemia was defined as serum levels > 15 μmol/L. RESULTS: The hyperuricemic patients showed significantly higher serum Hcy levels and lower estimated glomerular filtration rate (eGFR) than did normouricemic patients (13.39 ± 4.42 vs. 11.69 ± 3.65 μmol/L, P < 0.001; 85.16 ± 19.18 vs. 96.14 ± 16.63, P < 0.001, respectively). Serum Hcy level (odds ratio [OR], 1.050; 95% confidence interval [CI], 1.009–1.092) and fasting glucose level (OR, 1.018; 95% CI, 1.011–1.026) were independent risk factors for carotid plaque. In patients with hyperuricemia, the serum Hcy levels correlated with the eGFR (γ = −0.478, P < 0.001). The carotid IMT correlated with serum Hcy levels and eGFR (γ = 0.196, P = 0.008; γ = − 0.297, P < 0.001, respectively) but not with the serum lipid profile. CONCLUSION: These results suggest that renal function impairment in hyperuricemic patients may worsen carotid IMT by increasing serum Hcy levels.

ABSTRACT

PURPOSE: This study aimed to compare surgical revisions and balloon angioplasty after surgical thrombectomy on thrombosed dialysis access as a first event. MATERIALS AND METHODS: Records of patients undergoing creation of arteriovenous grafts (AVGs) at the Gachon University Gil Medical Center between March 2008 and February 2016 were reviewed. Among them, patients who underwent treatment on first-time thrombotic occlusion after AVG creation were identified. Outcomes were primary, primary-assisted, and secondary patency. The patency was generated using the Kaplan-Meier method, and patency rates were compared by log-rank test. RESULTS: A total of 59 de novo interventions (n=26, hybrid interventions; n=33, surgical revisions) for occlusive AVGs were identified. The estimated 1-year primary patency rates were 47% and 30% in the surgery and hybrid groups, respectively. The estimated primary patency rates were not different between the two groups (log-rank test, P=0.73). The Kaplan-Meier estimates of 6 and 12 months for primary-assisted patency rates were 68% and 57% in the surgery group and 56% and 56% in the hybrid group. The Kaplan-Meier estimates of 12 and 24 months secondary patency rates were 90% and 71% in the surgery group and 79% and 62% in the hybrid group. There were no differences in the estimated primary-assisted and secondary patency rates between the two groups. CONCLUSION: Our results showed no significant difference between the two groups in terms of primary patency (P=0.73), primary-assisted patency (P=0.85), and secondary patency (P=0.78). However, percutaneous transluminal angioplasty can give more therapeutic options for both surgeons and patients.

ABSTRACT

OBJECTIVE: Pulmonary hypertension (PH) develops frequently in connective tissue diseases (CTD) and is an important prognostic factor. The aim of this study was to assess the prevalence of PH in patients with CTD by non-invasive echocardiography and analyze the potential biomarkers for helping to detect PH. METHODS: All Korean patients with CTD who had dyspnea on exertion or interstitial lung disease (ILD) were screened for PH with echocardiography and clinical data were collected from four hospitals. RESULTS: Among 196 patients with CTD, 108 (55.1%) had ILD and 21 had PH defined as >40 mmHg. Of the 21 patients with PH, 10, 4, and 3 patients had systemic sclerosis, systemic lupus erythematosus, and mixed connective tissue disease, respectively. There was no difference in the incidence of PH according to the presence of ILD; 12 patients (11.1%) with ILD had PH and 9 patients (10.2%) without ILD had PH. The results of the pulmonary function test, total cholesterol, red cell volume distribution width, alkaline phosphatase, and the New York Heart Association (NYHA) functional class III or IV differed significantly according to the presence of PH. In multiple regression analysis, NYHA functional class III or IV (odd ratio [OR]=7.3, p=0.009) and forced vital capacity (OR=0.97, p=0.043) were independent predictive factors of PH. CONCLUSION: PH is not associated with the presence of ILD in Korean patients with CTD. On the other hand, NYHA functional class III or IV and decreased forced vital capacity indicate the presence of PH in connective tissue disease.

ABSTRACT

PURPOSE: In Korea, the incidence of breast cancer peaks in the fifth decade, which is younger than that observed in the Western world. We conducted this study to compare the clinical characteristics and prognostic factors of breast cancer in women < 35 and ≥35 years old.METHODS: The medical records of 969 patients treated for breast cancer at the Gil Medical Center from 2008 through 2012 were reviewed. Tumor characteristics, surgical methods, and adjuvant therapies were compared in two groups.RESULTS: Number of childbirths, family history, the proportion of postmenopausal women were lower among those aged < 35 years. However, tumor size, number of metastatic lymph nodes, and surgical procedures were similar in two groups. The rate of triple negative status in younger patients was higher than in older patients. Adjuvant chemotherapy was effective in patients positive for hormone receptors and no lymph nodal invasion, and it was effective in patients negative for hormone receptors and lymph nodal invasion in patients aged >35 years old. Postoperative radiotherapy was statistically effective in patients aged < 35 and ≥35 years old that underwent breast-conserving surgery. Pregnancy were significantly associated with survival in younger patients. While lymph node stage, presence of progesterone receptor, and triple negative status were significantly associated with survival on older patients.CONCLUSION: The prognostic factors of breast cancer in patients younger than 35 years old were pregnancy. Triple negative status rate was higher in younger patients than in older patients. Adjuvant therapy had similar effects in patients aged < 35 or ≥35 years old.

ABSTRACT

Relapsing polychondritis (RP) is a rare autoimmune disease that is characterized by inflammatory reaction of unknown etiology and destruction of cartilaginous structures. Characteristic symptoms of this disease include cartilage inflammation of the ear, nose, larynx, trachea, bronchi, joints, eyes, heart and skin. Concomitance with neurologic symptom is very rare in RP, and the detailed underlying mechanism of neurological involvement associated with RP is not fully understood. We herein described an unusual recurrent case of inflammatory brain lesions associated with RP, with attention to clinical manifestations, autoimmune disease involvement, and therapeutic effects.

ABSTRACT

Eosinophilic granulomatosis with polyangiitis (EGPA) is an immune related systemic disease that is caused by vasculitis affecting multiple organ systems. It is characterized by asthma, fever, eosinophilia, cardiac problems, renal injury, and peripheral neuropathy. In this report, we describe a patient with EGPA with concurrent cerebral infarction and acute polyneuropathy mimicking a Guillain-Barre syndrome (GBS). A 46-year-old man presented with rapidly progressing gait disturbance, muscular weakness, and tingling sensation in all four limbs. A nerve conduction study revealed sensorimotor polyneuropathy in all four limbs, and a test of the cerebrospinal fluid showed an albumin-cytologic dissociation. In addition, brain magnetic resonance imaging (MRI) using fluid-attenuated inversion recovery and diffusion weighted MRI revealed high signal intensity lesions with gadolinium enhancement on T1-weighted MRI in the right caudate nucleus. After performing laboratory tests, paranasal sinus computed tomography, and a nasal smear, the patient was diagnosed with EGPA and treated with high dose glucocorticoid and oral cyclophosphamide. In conclusion, our findings indicate that a diagnosis of EGPA should be considered when a patient presents with rapidly progressing polyneuropathy mimicking a GBS along with unusual systemic symptoms or brain lesions.

ABSTRACT

The main treatment for Antiphospholipid syndrome (APS) is long-term anticoagulation with an oral vitamin K antagonist, although these are associated with numerous problems. Rivaroxaban is a direct anti-factor Xa inhibitor, with a predictable anticoagulant effect at fixed doses. There are limited reports of rivaroxaban use in APS. We present four cases of patients with APS who received rivaroxaban treatment for six months without thrombosis recurrence or bleeding. Three of the patients received rivaroxaban as initial therapy. In the systematic review, only five patients were treated with rivaroxaban as a thromboprophylaxis. Of the 71 cases of rivaroxaban use including our study, there were seven cases (9.9%) of thrombosis recurrence and two reports of bleeding. The efficacy of rivaroxaban in APS patients was at least equal to warfarin therapy. This report and systematic review suggest that rivaroxaban can be considered cautiously as a thromboprophylactic or alternative therapy for warfarin in patients with APS.

ABSTRACT

PURPOSE: Patients with gout are similar to those with bacterial infection in terms of the nature of inflammation. Herein we compared the differences in procalcitonin (PCT) levels between these two inflammatory conditions and evaluated the ability of serum PCT to function as a clinical marker for differential diagnosis between acute gouty attack and bacterial infection. MATERIALS AND METHODS: Serum samples were obtained from 67 patients with acute gouty arthritis and 90 age-matched patients with bacterial infection. Serum PCT levels were measured with an enzyme-linked fluorescent assay. RESULTS: Serum PCT levels in patients with acute gouty arthritis were significantly lower than those in patients with bacterial infection (0.096±0.105 ng/mL vs. 4.94±13.763 ng/mL, p=0.001). However, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels showed no significant differences between the two groups. To assess the ability of PCT to discriminate between acute gouty arthritis and bacterial infection, the areas under the curves (AUCs) of serum PCT, uric acid, and CRP were 0.857 [95% confidence interval (CI), 0.798-0.917, p<0.001], 0.808 (95% CI, 0.738-0.878, p<0.001), and 0.638 (95% CI, 0.544-0.731, p=0.005), respectively. There were no significant differences in ESR and white blood cell counts between these two conditions. With a cut-off value of 0.095 ng/mL, the sums of sensitivity and specificity of PCT were the highest (81.0% and 80.6%, respectively). CONCLUSION: Serum PCT levels were significantly lower in patients with acute gouty attack than in patients with bacterial infection. Thus, serum PCT can be used as a useful serologic marker to differentiate between acute gouty arthritis and bacterial infections.

ABSTRACT

A 62-year-old male with a smoking history of 30 pack-years presented with a 1-year history of a periumbilical pulsating mass. He had been treated for hypertension for 2 years. Physical examination revealed a huge pulsating mass in the periumbilical abdomen. Femoral and popliteal arterial pulses were palpable. Computed tomography showed arterial dissection in the proximal segment of the superior mesenteric artery, a huge aneurysm (52×50 mm) with mural thrombus and two smaller aneurysms (20×20 mm) in the right ileocolic and ileal branches, along with atherosclerotic changes. Interposition using the great saphenous vein was performed after aneurysmal isolation and ligation of jejunal branches in the sac. Distal flow was reestablished by end-to-end and end-to-side anastomoses of the right ileocolic and ileal branches, respectively. No complications were observed at 1-year follow-up.

ABSTRACT

OBJECTIVE: Gout is known to be associated with cardiovascular disease (CVD), and hyperhomocysteinemia is one of the risk factors for CVD. We investigated the associations between the change of serum homocysteine (Hcy) level and those of the other parameters including serum uric acid level, renal function, and cholesterol profiles in chronic gout patients with longitudinal follow-up data. METHODS: Ninety-one male patients with chronic gout and 97 age-matched healthy male control subjects were included in the previous study. Among them, 33 patients with gout and 39 healthy control subjects underwent follow-up tests for Hcy levels with an average of 24.00+/-9.12 months in this study. RESULTS: The follow-up data showed that gout patients had significantly higher levels of Hcy in serum than control subjects (16.75+/-5.43 micromol/L vs. 13.17+/-3.83 micromol/L, p=0.002). In gout patients, the change of serum Hcy level after follow up showed positive correlation with the change of creatinine (gamma=0.442, p=0.009) and negative correlation with estimated glomerular filtration rate (eGFR; gamma=-0.528, p<0.001). However, the change of serum Hcy level did not show correlation with the changes of uric acid level or the lipid profiles. CONCLUSION: Serum Hcy level was elevated in gout patients compared with control subjects. The change of serum Hcy level showed negative correlation with the change of eGFR. Hyperhomocysteinemia in gout patients was associated with decreased renal function, but not with serum uric acid or lipid profiles.
