ABSTRACT

Drug addiction is a major worldwide medical and social problem.Cocaine,nicotine,methamphetamine,heroin and other psychoactive substances,with small molecular weight,can easily cross the blood-brain barrier and eventually lead to addiction and other serious neuropsychological damage.There is no effective cure for addiction currently.The drug-antibody complex formed on the basis of active or passive immunotherapy could not cross the blood-brain barrier,which reduces the concentration of the free active drug and prevents its distribution in the brain,thereby weakening the drug addiction-related reward effects.It provides a promising way for the treatment of drug addiction.This article reviews the progress of immunotherapy against psychoactive substances such as cocaine,nicotine,methamphetamine and heroin in the past 50 years from the aspects of active immunity,passive immunity,drug metabolism-related enzymes,adjuvants and so on.The goal is to provide some ideas for the development of agents for the treatment of psychoactive substance addiction.

ABSTRACT

Objective:To compare the effects of XELOX (oxaliplatin + capectabine) regimen and FOLFOX4 (oxaliplatin + calcium leucovorin + fluorouracil) regimen on colon cancer and their influences on serum tumor markers and cytological indexes.Methods:A total of 84 patients with colon cancer treated in Wuhu Hospital of Chinese Medicine of Anhui Province from January 2016 to January 2019 were selected, and the patients were randomly divided into the observation group (XELOX regimen, 42 cases) and the control group (FOLFOX4 regimen, 42 cases) according to the random number table. The efficacy, side effects, the changes of cytological indicators and serum tumor markers before and after chemotherapy between the two groups were compared.Results:The short-term effective rate was 76.19% (32/42) in the observation group and 61.91% (26/42) in the control group, and the difference was not statistically significant (χ 2 = 2.005, P=0.156). The incidence of side effects in the observation group was lower than that in the control group [35.71% (15/42) vs. 59.53% (25/42), χ 2 = 4.773, P = 0.029]. There was no significant difference in the levels of carbohydrate antigen 199 (CA19-9), colon cancer-specific antigen (CCSA-2) and osteopontine (OPN) between the two groups before treatment (all P > 0.05); after treatment, CA19-9, CCSA-2, OPN levels were lower than those before treatment of the two groups (all P < 0.05); after treatment, CA19-9, CCSA-2, OPN levels in the observation group were lower than those in the control group (all P < 0.05). Before treatment, there was no significant difference in the levels of neutrophils to lymphocytes ratio (NLR), platelet-lymphocytes ratio (PLR), and red cell distribution width (RDW) between the two groups (all P > 0.05); the levels of NLR, PLR and RDW after treatment in the two groups were decreased compared with those before treatment (all P < 0.05); NLR, PLR and RDW levels in the observation group after treatment were lower than those in the control group (all P < 0.05). In the observation group, the recurrence rate of 1-year, 2-year, 3-year was 4.76% (2/42), 14.26% (6/42), and 19.05% (8/42), respectively; in the control group, the recurrence rate of 1-year, 2-year, 3-year was 11.90% (5/42), 21.43% (9/42), and 26.19% (11/42), respectively; there was no statistical difference between the two groups (all P > 0.05); in the observation group, the survival rate of 1-year, 2-year, 3-year was 92.86% (39/42), 78.57% (33/42), and 71.43% (30/42), respectively; in the control group, the survival rate of 1-year, 2-year, 3-year was 85.71% (36/42), 69.05% (29/42), and 64.28% (27/42), and there was no statistically significant difference between the two groups (all P > 0.05). Conclusions:XELOX regimen and FOLFOX regimen have similar short-term and long-term effects on patients with colon cancer. They both can decrease the levels of serum tumor markers and cytological indicators of patients, and improve their prognosis, while XELOX regimen has low side effects.

ABSTRACT

BACKGROUND@#Clinical observational studies revealed that 99Tc-methylene diphosphonate (99Tc-MDP) could reduce joint pain and swollenness in rheumatoid arthritis (RA) patients. This multicenter, randomized, double-blind, double-dummy study aimed to evaluate the effects of 99Tc-MDP plus methotrexate (MTX) vs. MTX alone or 99Tc-MDP alone on disease activity and structural damage in MTX-naïve Chinese patients with moderate to severe RA.@*METHODS@#Eligible patients with moderate to severely active RA were randomized to receive 99Tc-MDP plus MTX (n = 59) vs. MTX (n = 59) alone or 99Tc-MDP (n = 59) alone for 48 weeks from six study sites across four provinces in China. The primary outcomes were the American College of Rheumatology 20% improvement (ACR20) response rates at week 24 and changes in modified total Sharp score at week 48.@*RESULTS@#At week 24, the proportion of participants achieving ACR20 was significantly higher in the MTX + 99Tc-MDP combination group (69.5%) than that in the MTX group (50.8%) or 99Tc-MDP group (47.5%) (P = 0.03 for MTX + 99Tc-MDP vs. MTX, and MTX + 99Tc-MDP vs.99Tc-MDP, respectively). The participants in the MTX + 99Tc-MDP group and the 99Tc-MDP group had significantly less important radiographic progression than the participants in the MTX group over the 48 weeks (MTX + 99Tc-MDP vs. MTX: P = 0.03, 99Tc-MDP vs. MTX: P = 0.03, respectively). There was no significant difference in terms of adverse events (AEs) among the groups. No serious AEs were observed.@*CONCLUSIONS@#This study demonstrated that the combination of 99Tc-MDP with MTX inhibited structural damage and improved disease activity in RA patients compared with MTX and 99Tc-MDP monotherapies, without increasing the rate of AEs. Additional clinical studies of 99Tc-MDP therapy in patients with RA are warranted.@*TRIAL REGISTRATION@#Chictr.org, ChiCTR-IPR-14005684; http://www.chictr.org.cn/showproj.aspx?proj=10088.

ABSTRACT

Osteoprotegerin (OPG), secreted by osteoblasts, is a marker of bone turnover. OPG can inhibit osteoclastic differentiation by binding receptor activator of nuclear factor-κB ligand (RANKL). In this study, we found that rutaecarpine (RUT) had the up-regulating OPG activity, and it could significantly increase OPG protein levels in both mouse embryonic osteogenic precursor MC3T3-E1 and human osteosarcoma U-2OS cells. Osteoblastogenic differentiation calcified nodules staining results showed that RUT significantly promoted the osteogenic differentiation of MC3T3-E1 cells. Osteoclastic differentiation tartrate resistant acid phosphatase (TRAP) staining results showed that RUT obviously inhibited the osteoclast differentiation of mouse macrophages RAW264.7 induced by RANKL. In vivo studies showed that low-dose RUT group (5 mg·kg-1·day-1) and high-dose RUT group (45 mg·kg-1·day-1) treatments for 3 months significantly increased bone density in ovariectomized (OVX) rats; calcein double labeling experiment and toluidine blue staining results indicated that low-dose RUT group promoted bone formation and decreased bone loss in vivo; immunohistochemistry results showed that low-dose RUT group increased the expression of OPG in rat femur. All animal procedures were performed in accordance with the regulations of the Institutional Animal Care and Use Committee of Institute of Medicinal Biotechnology, Chinese Academy of Medical Sciences. In summary, this study demonstrated that RUT could up-regulate OPG expression and had promoting osteoblastic differentiation and inhibiting osteoclastic differentiation effects in vitro and in vivo.

ABSTRACT

Objective: By observing the effects of electroacupuncture (EA) on the apoptosis of conjunctival cells of rabbits with dry eye syndrome (DES) and the expressions of apoptosis-related proteins Caspase-3, Fas and Bcl-2, to discuss the mechanism of EA in the treatment of DES from the perspective of cell apoptosis. Methods: Male New Zealand rabbits were randomly divided into a normal group (NG), a model group (MG), an EA group (EAG) and a sham EA group (SEAG). DES rabbit model was developed by eye drop of 0.1% benzalkonium chloride. The rabbit tear secretion and tear film break-up time (BUT) were measured; terminal deoxynucleotidyl transferase- mediated dUTP nick end labeling (TUNEL) assay was used to detect the apoptosis of conjunctival cells; the expressions of Caspase-3, Fas and Bcl-2 proteins in conjunctival cells were detected by immunohistochemistry. Results: Compared with the NG, the rabbit tear secretion decreased and the BUT was shortened in the MG (both P<0.01); compared with the MG and the SEAG, the rabbit tear secretion increased and the BUT was prolonged in the EAG (all P<0.05). Compared with the NG, the apoptosis of rabbit conjunctival cells increased (P<0.01), the expressions of Caspase-3 and Fas proteins increased (both P<0.05), and the expression of Bcl-2 protein decreased (P<0.01) in the MG; compared with the MG and the SEAG, the apoptosis of rabbit conjunctival cells decreased (both P<0.01), the expressions of Caspase-3 and Fas proteins decreased (all P<0.05), and the expression of Bcl-2 protein increased (both P<0.01) in the EAG. Conclusion: EA can inhibit the apoptosis of rabbit conjunctival cells, down-regulate the expressions of apoptosis-related proteins Caspase-3 and Fas, and up-regulate the expression of Bcl-2 protein, which may be one of the mechanisms of EA in treatment of DES.

ABSTRACT

Objective: To observe the clinical efficacy of Zhen'ai needling method in Nei Jing (Classic of Internal Medicine) for children with allergic rhinitis (AR) accompanied by adenoid hypertrophy (AH). Methods: A total of 74 children who met the screening criteria were divided into a Zhen'ai group and a control group by the random number table method, with 37 cases in each group. The control group was treated with acupuncture at Zusanli (ST 36), Hegu (LI 4), Yingxiang (LI 20), Juliao (ST 3), Yintang (GV 29), Shangxing (GV 23) and Baihui (GV 20). The Zhen'ai group added points of Zhen'ai needling method {Shanglianquan [Extra, located at 1 cun above Lianquan (CV 23)], Tianrong (SI 17) and Lieque (LU 7)} in addition to the points in the control group. The needles were retained for 30 min. The treatment was performed twice a week. The total nasal symptom score (TNSS), sino-nasal outcome test-20 (SNOT-20) and symptom scale for AH (SSAH) were assessed before and after 10 treatments. The clinical efficacy of the two groups was compared after treatment. Results: During the treatment, 5 cases dropped out in the control group and 2 cases in the Zhen'ai group. After treatment, the total effective rate of the Zhen'ai group was 94.3%, versus 93.8% in the control group. There was no significant difference between the two groups (P>0.05). The markedly effective rate of the Zhen'ai group was 42.9%, versus 12.5% in the control group, and the difference was statistically significant (P<0.05). After treatment, there were significant intra-group differences in the scores of TNSS, SNOT-20 and SSAH in both groups (all P<0.05); the scores of SNOT-20 and SSAH in the Zhen'ai group were lower than those in the control group, and the differences between the groups were statistically significant (both P<0.05). Conclusion: Both conventional acupuncture and conventional acupuncture plus Zhen'ai needling method can improve clinical symptoms of children with AR accompanied by AH; and conventional acupuncture plus Zhen'ai needling method has a better effect than conventional acupuncture in improving AH symptoms.

ABSTRACT

Objective To analyze the endemic situation of schistosomiasis in Hunan Province in 2019, so as to provide insights into the achievement of transmission interruption of schistosomiasis in the province in 2020. Methods The data pertaining to Schistosoma japonicum infections in humans and livestock and snail status were captured from Hunan Province in 2019 and analyzed. Results Schistosomiasis was endemic in 281 townships (towns) from 41 counties (districts) of 6 cities in Hunan Province by the end of 2019. A total of 991 900 persons received blood testing in Hunan Province in 2019, and 22 773 were positive for the blood testing, with sero-prevalence of 2.30%. All stool examinations were negative in 22 933 individuals detected. The high sero-prevalence was seen in Nanxian County, Anxiang County and Ziyang District. Currently, there were 5 034 cases with advanced schistosomiasis detected in Hunan Province, and they were predominantly identified in Yuanjiang City, Heshan District and Yueyang County. There were 44 963 bovines fenced in schistosomiasis-endemic villages in Hunan Province in 2019, which were predominantly distributed in Yuanjiang City, Hanshou County and Ziyang District, and no positives were detected in 1 996 bovines receiving blood testing or 20 684 bovines receiving stool examinations. In 2019, there were snail habitats of 1.73 billion m2 found in Hunan Province, which were mainly found in Yuanjiang City, Hanshou County and Yueyang County. Conclusion The endemic situation of schistosomiasis further decreases in Hunan Province in 2019; however, there is still a risk of schistosomiasis transmission in local areas of the province.

ABSTRACT

Objective To analyze the changes in the endemic situation of schistosomiasis in national surveillance sites of Hunan Province, so as to provide scientific basis for the development of the schistosomiasis elimination programme in the province. Methods According to the requirements of the National Guidelines for Schistosomiasis Surveillance in China (2014 version), a total of 41 national schistosomiasis surveillance sites were assigned in all disease-endemic counties (districts) across Hunan Province. During the period between 2015 and 2019, Schistosoma japonicum infections were monitored in local residents, mobile populations and livestock, and snail status was monitored. The morbidity due to schistosomiasis and snail status was compared between years. Results The sero-prevalence of S. japonicum infections was 2.57% and 1.56% in local residents and mobile populations in national surveillance sites of Hunan Province from 2015 to 2019, respectively, and the sero-prevalence appeared a tendency towards a decline over years. A higher sero-prevalence rate of S. japonicum infections was seen in men than in women (P < 0.01). During the 5-year study period, the sero-prevalence rate of human S. japonicum infections appeared a tendency towards a decline in the marshland, embankment, inner embankment and hilly types of endemic areas over years. There were 44 and 19 egg -positives detected in local residents and 5 and 1 egg-positives in mobile populations in 2015 and 2016 respectively. A total of 9 346 domestic animals were monitored from 2015 to 2019, and 6 egg-positives were detected in 2015 and 2016 (all were bovine). A total of 0.155 billion m2 settings were surveyed from 2015 to 2019, and the mean density of living snails appeared a tendency towards a decline over years, with a 45.79% reduction in 2019 as compared to 2015. However, no S. japonicum infections were identified in snails during the 5-year period. A total of 1 469 mixed snail samples were detected using loop-mediated isothermal amplification (LAMP), and 6 positive snail samples were identified in 2015 (one sample) and 2017 (5 samples). Conclusions The overall endemic situation of schistosomiasis appears a tendency towards a decline in Hunan Province, and the prevalence of S. japonicum infections is at a low level in humans and livestock; however, there is still a risk of schistosomiasis transmission. Improvements of health education, intensification of schistosomiasis examinations in mobile populations and reinforcement of the surveillance-response system is required to consolidate the achievements of schistosomiasis control in Hunan Province.

ABSTRACT

Objective To examine the effect of the integrated schistosomiasis control measures in Hunan Province from 2004 to 2019, so as to provide insights into the development of the schistosomiasis elimination strategy. Methods The integrated schistosomiasis control measures implemented by the health, agriculture, water resources, forestry, land and resources sectors were retrospectively collected in Hunan Province from 2004 to 2019, and the completion of each measure, cost of control measures, Schistosoma japonicum infections in humans and bovines, and snail status were analyzed each year. An index system for assessing the integrated schistosomiasis control effect was constructed using the Delphi method to calculate the integrated schistosomiasis control effect index. In addition, a cost-effect analysis was performed in terms of the decline in the prevalence of S. japonicum infections in humans and bovines, areas with snails in inner embankments, and areas with infected snails. Results A total of 7 110 926 500 Yuan were invested into the integrated schistosomiasis control program of Hunan Province from 2004 to 2019. During the 16-year period, a total of 277 437.12 hm2 snail habitats received molluscicidal treatments, 6 927 230 person-times given expanded chemotherapy, 2 116 247 bovine-times given expanded chemotherapy, 954 850 harmless toilets built, 290 359 bovines fenced, 136 666 bovines eliminated, 141 905 machines used to replace bovines, 39 048.63 hm2 water lands improved as dry lands, 724.12 km irrigation regions improved, 3 994 300 populations covered with safe water, 191 102.89 hm2 forests planted and 38 535.27 hm2 lands leveled. The prevalence of S. japonicum infections was 4.29% in humans and 4.48% in bovines in Hunan Province in 2004, with 2 449.37 hm2 snail habitats in inner embankments and 3 423.74 hm2 infected snail areas. In 2019, the prevalence of S. japonicum infections reduced to 0 in both humans and bovines, and areas of snail habitats reduced to 540.92 hm2 (77.92% reductions), while the areas with infected snails reduced to 0. The overall integrated schistosomiasis control effect index appeared a tendency towards a rise over years since 2004, and the integrated schistosomiasis control effect index was 97.35 in 2019; the annual mean costs for a 1% reduction in the prevalence of S. japonicum infections in 100 populations and 100 bovines were 70.11 Yuan and 4 204.78 Yuan, and the annual mean costs for a 1% reduction in the snail areas in inner embankments and infected snail areas were 2 010.20 Yuan and 1 298.09 Yuan, respectively. Conclusions The integrated control measures achieve remarkable effectiveness for schistosomiasis control in Hunan Province, with a remarkable decline in the prevalence of S. japonicum infections in humans and bovines and great shrinking of snail areas in inner embankments and infected snail areas. Adequate fund investment is required to improve the integrated schistosomiasis control measures and consolidate the control achievements.

ABSTRACT

OBJECTIVE@#To explore the clinical application value of serum light chain (sLC) in the diagnosis and therapeutic efficacy evaluation for multiple myeloma.@*METHODS@#46 patients with newly diagnosed multiple myeloma were selected as MM group and 50 healthy persons as control group. Rate scattering immunoturbidimetry was used to detect serum light chain and immunoglobulin (Ig) in two groups, serum protein electrophoresis was used to detect M protein by agarose gel. Then, the sensitivity and specificity of the two methods in MM diagnosis were analyzed and compared, and the significance of sLC detection in MM diagnosis were discussed. In addition, 15 MM patients after received conventional therapy were tracked, sLC levels in five different therapentic times were recorded, and the effect of sLC in efficacy evaluation of MM was analyzed.@*RESULTS@#There were 11 cases of IgA type, 15 cases of IgG type, 8 cases of light chain κ type, 8 cases of light chain λ type, 2 cases of IgD type, and 2 cases of non-secretion type. The sLC-κ, sLC-λ and their ratio (including light chain type and double clone type), IgA and IgG (except IgD type), as well as albumin, beta-globulin and gamma-globulin levels showed statistically significant differences (P<0.05) compared with the control group. The sensitivity of serum protein electrophoresis, Ig quantification, sLC and its ratio in the diagnosis of multiple myeloma were 57%, 76% and 65%, and their specificity were 83%, 61% and 90%, respectively. After the second or third chemotherapy, the sLC-κ/λ ratio gradually approached the normal range as the disease reliefes, and the sLC-κ/λ ratio continued to be on or off the line at outliers or further away from the reference value as the disease progresses in MM patients with κ type or λ type.@*CONCLUSION@#sLC detection shows positive significance in early diagnosis of multiple myeloma, SLC monitoring can be used for the efficacy evaluation for treatment of MM patients.

ABSTRACT

Total flavones of Abelmoschus manihot L. Medic [TFA] is the major active component isolated from Chinese herb Abelmoschus manihot L. Medic. TFA has shown neuroprotective effect against cerebral ischemia injury in rats and rabbits. However, the effects of TFA on hind-limb ischemia and the underlying mechanisms remain unclear. Therefore, in the present study, we used a rat hind-limb ischemia model to investigate protective effect of TFA against limb ischemia injury. The rat model of hind-limb ischemia was established. Treatment groups received TFA at two different doses [160 and 40mg/kg] daily for 10 days. Sham operated control group and model group received saline. At the end the rats were sacrificed, hindlimb tissues were stained with Haematoxylin-Eosin and Masson's trichrome. RNA and protein were extracted from tissues for PCR and Western blot analysis. The results showed that TFA reduced lower limb ischemic injury, recovered tissue volume and diminished fibrosis and muscle degeneration. Mechanistically, we showed that TFA increased the expression of anti-apoptotic factor such as Bcl-2 and survivin, decreased the expression of pro-apoptotic factor such as Caspase 3, Bax and Bak and inhibited the activation of caspase 3 and 9. In summary, this study proves new evidence that TFA protects hind-limb against ischemia injury by inhibiting apoptosis and could be a promising therapeutic agent for acute lower extremity ischemia

ABSTRACT

Objective@#To determine the relationship between volume of epicardial adipose tissue (EAT) and atrial fibrillation (AF) .@*Methods@#A total of 207 patients who hospitalized in the Department of Cardiology, Nantong University Affiliated Hospital from January 2016 to June 2018 were included in this study. They were divided into two groups, including AF group (n=125) and sinus rhythm group (n=82). The AF group included 80 paroxysmal AF (PAF) and 45 persistent AF (PeAF) patients. Total EAT and left atrial EAT (LA-EAT) volume were measured using 256 rows of multi-slice spiral CT in all patients. Echocardiographic derived left ventricular ejection fraction (LVEF) and left atrial diameter (LAD) were analyzed. Hospholipase A2 and blood lipids were examined in all patients. The baseline data and EAT volume of all groups were compared. The multivariate logistic regression was used to analyze the risk factors related to the occurrence of AF. The correlation between total EAT volume and LA-EAT volume and LAD were analyzed by Pearson correlation.@*Result@#The volume of total EAT in patients with sinus rhythm, AF, PAF and PeAF were (92.2±32.1), (136.0±46.0), (134.2±46.3) and (140.1±52.6)cm3, respectively. The volume of LA-EAT in patients with sinus rhythm, AF, PeAF and PAF were (27.1±7.5), (39.2±19.2), (35.9± 17.0) and (45.1±21.5)cm3, respectively. Total EAT and LA-EAT volume were significantly larger in PAF and PeAF groups than in sinus rhythm group (all P<0.01). The LA-EAT volume was larger in PeAF group than in PAF group (P<0.01), but total EAT volume was similar between two groups (P>0.05). Logistic regression analysis showed that total EAT volume (OR=1.202, 95%CI 1.083-1.334, P=0.001), LA-EAT volume (OR=1.051, 95%CI 1.003-1.101, P=0.037) and LAD (OR=1.019, 95%CI 1.005-1.032, P=0.006) were the independent related factors of AF. Pearson correlation analysis showed that the total EAT volume was positively correlated with LAD (r=0.466, P<0.01) and LA-EAT volume was positively correlated with LAD (r=0.290, P<0.01).@*Conclusion@#The volume of total EAT and LA-EAT measured by 256-row multi-slice spiral CT is significantly correlated with the incidence of AF.

ABSTRACT

BACKGROUND: Previous Caucasian studies have described venous thromboembolism in pregnancy; however, little is known about its incidence during pregnancy and early postpartum period in the Chinese population. We investigated the risk of venous thromboembolism in a “real-world” cohort of pregnant Chinese women with no prior history of venous thromboembolism. METHODS: In this observational study, 15,325 pregnancies were identified in 14,162 Chinese women at Queen Mary Hospital, Hong Kong between January 2004 and September 2016. Demographic data, obstetric information, and laboratory and imaging data were retrieved and reviewed. RESULTS: The mean age at pregnancy was 32.4±5.3 years, and the median age was 33 years (interquartile range, 29–36 yr). Pre-existing or newly diagnosed diabetes mellitus was present in 627 women (4.1%); 359 (0.7%) women had pre-existing or newly detected hypertension. There was a small number of women with pre-existing heart disease and/or rheumatic conditions. Most deliveries (86.0%) were normal vaginal; the remaining were Cesarean section 2,146 (14.0%). The incidence of venous thromboembolism was 0.4 per 1,000 pregnancies, of which 83.3% were deep vein thrombosis and 16.7% were pulmonary embolism. In contrast to previous studies, 66.7% of venous thrombosis occurred in the first trimester. CONCLUSION: Chinese women had a substantially lower risk of venous thromboembolism during pregnancy and the postpartum period compared to that of Caucasians. The occurrence of pregnancy-related venous thromboembolism was largely confined to the early pregnancy period, probably related to the adoption of thromboprophylaxis, a lower rate of Cesarean section, and early mobilization.

ABSTRACT

BACKGROUND@#Clinical outcomes of undifferentiated arthritis (UA) are diverse, and only 40% of patients with UA develop rheumatoid arthritis (RA) after 3 years. Discovering predictive markers at disease onset for further intervention is critical. Therefore, our objective was to analyze the clinical outcomes of UA and ascertain the predictors for RA development.@*METHODS@#We performed a prospective, multi-center study from January 2013 to October 2016 among Chinese patients diagnosed with UA in 22 tertiary-care hospitals. Clinical and serological parameters were obtained at recruitment. Follow-up was undertaken in all patients every 12 weeks for 2 years. Predictive factors of disease progression were identified using multivariate Cox proportional hazards regression.@*RESULTS@#A total of 234 patients were recruited in this study, and 17 (7.3%) patients failed to follow up during the study. Among the 217 patients who completed the study, 83 (38.2%) patients went into remission. UA patients who developed RA had a higher rheumatoid factor (RF)-positivity (42.9% vs. 16.8%, χ = 8.228, P = 0.008), anti-cyclic citrullinated peptide (CCP) antibody-positivity (66.7% vs. 10.7%, χ = 43.897, P < 0.001), and double-positivity rate of RF and anti-CCP antibody (38.1% vs. 4.1%, χ = 32.131, P < 0.001) than those who did not. Anti-CCP antibody but not RF was an independent predictor for RA development (hazard ratio 18.017, 95% confidence interval: 5.803-55.938; P < 0.001).@*CONCLUSION@#As an independent predictor of RA, anti-CCP antibody should be tested at disease onset in all patients with UA.
