Effect of remission, clinical remission with active serology, and glucocorticoid dosage on the pregnancy outcome of pregnant patients with systemic lupus erythematosus.

BACKGROUND: Remission is a key treatment target in systemic lupus erythematosus (SLE) management. Given the direct correlation between lupus flares and elevated risks of adverse pregnancy outcomes (APOs), securing remission before conception becomes crucial. However, the association between clinical remission with active serology, and the risk of APOs is not thoroughly understood. Additionally, determining the optimal glucocorticoid dosage during pregnancy to mitigate APO risks remains under-researched. This study investigated the risk of APOs in relation to remission/serological activity status in patients in clinical remission/glucocorticoid dosage. METHODS: Pregnant patients with SLE, who were followed up at two Japanese tertiary referral centers, and had their remission status assessed at conception, were included in this study. We categorized the patients into two groups based on whether they achieved Zen/Doria remission at conception and analyzed the APO ratio. We also examined the influence of serological activity in pregnant patients with clinical remission and analyzed the optimal glucocorticoid dosage to minimize the APO ratio. RESULTS: Of the 96 pregnancies included, 59 achieved remission at conception. Pregnant patients who achieved remission showed a significant decrease in the APO ratio compared with those who did not. (overall APO: odds ratio (OR) 0.27, 95% confidence interval (CI) 0.11-0.65, p < 0.01, maternal APO: OR 0.34, 95%CI 0.13-0.85, p = 0.021, neonatal APO: OR 0.39, 95%CI 0.17-0.90, p = 0.028). Conversely, no statistical difference was observed in the APO ratio based on serological activity in pregnant patients with clinical remission. (overall APO: OR 0.62, 95%CI 0.21-1.79, p = 0.37, maternal APO: OR 1.25, 95%CI 0.32-4.85, p = 0.75, neonatal APO: OR 0.83, 95%CI 0.29-2.39, p = 0.73). A glucocorticoid dose of prednisolone equivalent ≥ 7.5 mg/day at conception correlated with increased APO. (overall APO: OR 3.01, 95%CI 1.23-7.39, p = 0.016, neonatal APO: OR 2.98, 95% CI:1.23-7.22, p = 0.016). CONCLUSIONS: Even with active serology, achieving clinical remission can be a clinical target for reducing APOs in patients who wish to conceive. In addition, if clinically feasible, reducing the glucocorticoid dosage to < 7.5 mg/day before conception could be another predictive factor.

Changes in alcohol intake and serum urate changes: longitudinal analyses of annual medical examination database.

INTRODUCTION: Despite the established cross-sectional association between alcohol intake and serum urate (SU), its longitudinal association remains unknown. This study aimed to determine whether changes in alcohol intake have a clinically relevant association with SU change. METHOD: We conducted retrospective analyses using systematically collected annual medical examination data from October 2012 to October 2022 in a Japanese preventive medicine centre. The exposure was changes in alcohol intake between two consecutive visits. The association of SU changes with alcohol intake changes was estimated by mixed-effect linear regression with adjustment for relevant covariates. RESULTS: We analysed 63 486 participants (median age, 47.0 years; 55% women; 58.6% regular alcohol drinkers with a median of 1.4 drinks/day) with 370 572 visits. The median SU level was 5.3 mg/dL, and 506 (0.8%) participants had diagnoses of gout or hyperuricemia without medication use during the study period. Decreasing one daily alcohol intake had a clinically small association with SU changes (-0.019 (95% CI: -0.021 to -0.017) mg/dL). Beer had the largest association with SU (-0.036 (95% CI: -0.039 to -0.032) mg/dL for one beer decrease). Complete discontinuation of any alcohol from a mean of 0.8 drinks/day was associated with -0.056 mg/dL (95% CI: -0.068 to -0.043) decrease in SU; the association became larger in hyperuricemic participants (-0.110 mg/dL (95% CI: -0.154 to -0.066) for alcohol discontinuation from a mean of 1.0 drinks/day). CONCLUSIONS: This study revealed changes in alcohol intake had small associations with SU change at the general Japanese population level. Complete discontinuation of alcohol in hyperuricemic participants had only modest improvement in SU.

A retrospective analysis of the safety of tacrolimus use and its optimal cut-off concentration during pregnancy in women with systemic lupus erythematosus: study from two Japanese tertiary referral centers.

BACKGROUND: Tacrolimus is one of the major treatment options for systemic lupus erythematosus (SLE) and is considered to be a pregnancy-compatible medication. Since little is known about tacrolimus safety during pregnancy complicated by SLE, this study was designed. METHODS: We included SLE pregnant patients who were followed up at two Japanese tertiary referral centers. We performed multivariate logistic regression analysis to assess each adverse pregnancy outcome (APO) risk. Moreover, we assessed the influence of tacrolimus on the APO ratio in pregnant patients with lupus nephritis, and the impact of combined tacrolimus-aspirin therapy on the APO ratio relative to patients exclusively administered tacrolimus. RESULTS: Of the 124 pregnancies, 29 were exposed to tacrolimus. Multivariate analysis showed no statistical difference in APO ratio. (overall APO: adjusted odds ratio [aOR], 0.69; 95% confidence interval [CI], 0.23-2.03; p = 0.50; maternal APO: aOR, 1.17; 95% CI, 0.36-3.83; p = 0.80; neonatal APO: aOR, 1.10; 95% CI, 0.38-3.21; p = 0.86; PROMISSE APO: aOR, 0.50; 95% CI, 0.14-1.74; p = 0.27). Blood pressure and estimated glomerular filtration rate (eGFR) during pregnancy and after delivery did not differ between the two groups. Receiver operating characteristic (ROC) curve showed that tacrolimus concentration > 2.6 ng/ml was related to reduced preterm birth rate. (AUC = 0.85, 95% CI: 0.61-1.00, sensitivity: 93% and specificity: 75%). Regarding effect of tacrolimus on lupus nephritis during pregnancy, tacrolimus showed no increased risk of APO, blood pressure or eGFR during pregnancy and after delivery. (overall APO: OR, 1.00; 95% CI, 0.25-4.08; p = 0.98; maternal APO: OR 1.60, 95% CI, 0.39-6.64; p = 0.51; neonatal APO: OR, 0.71; 95% CI, 0.17-3.03; p = 0.65, PROMISSE APO: OR, 0.50; 95% CI, 0.08-3.22; p = 0.47). Tacrolimus-aspirin combination therapy showed a protective tendency against hypertensive disorders during pregnancy, preeclampsia and low birth weight. CONCLUSIONS: Tacrolimus use during pregnancy with SLE and lupus nephritis showed no significant influence on APO, blood pressure, or renal function; therefore tacrolimus may be suitable for controlling lupus activity during pregnancy. In addition, when using tacrolimus during pregnancy, we should aim its trough concentration ≥ 2.6 ng/ml while paying careful attention to possible maternal side effects of tacrolimus. TRIAL REGISTRATION: Retrospectively registered.

Disease-modifying effect and long-term safety of belimumab in patients with systemic lupus erythematosus: A single-center retrospective study.

BACKGROUND: Disease modification in systemic lupus erythematosus (SLE) is important for minimizing disease activity while limiting treatment-associated toxicities. Belimumab can be used as a remission-induction/maintenance systemic lupus erythematosus therapy; however, its disease-modifying effects are unclear. We aimed to determine these effects in patients with systemic lupus erythematosus. METHODS: This single-center retrospective cohort study included 92 patients with systemic lupus erythematosus treated with belimumab. We analyzed the changes in flare free rate/lupus low disease activity state (LLDAS) attainment rate/glucocorticoid dosage/Systemic Lupus International Collaborating Clinics and American College of Rheumatology damage index (SDI) score/drug retention rate after treatment initiation. RESULTS: Fifty-two weeks after initiating belimumab, the flare rate decreased from 82.6% to 14.1% (p < .01). Until week 52 and 1000 days after initiating belimumab treatment, > 70% and ∼90% of the patients attained lupus low disease activity state, respectively. Belimumab treatment significantly reduced glucocorticoid demand (initiation day, 8.88 (6.00-15.00) mg/d; week 52, 5.00 (2.00-7.00) mg/d; final day of the study period, 3.00 (0.46-6.06) mg/d, initiation day vs. week 52: p < .01, initiation day vs. final day: p < .01); at the end of the study period, 68.5% of patients required ≤5 mg/d prednisolone, and 22.8% discontinued glucocorticoids. Most patients were SDI progression-free (week 52, ∼95%; day 1000, ∼90%), and belimumab showed a high drug retention rate (week 52, 90%; day 1000 > 80%). CONCLUSION: Most patients experienced lupus low disease activity state, reduced flare rate and glucocorticoid demand, and a stable SDI trend after belimumab treatment initiation. Given its efficacy and retention rate, belimumab treatment may serve as a fundamental strategy in disease modification.

Differences in the Association Between Alcoholic Beverage Type and Serum Urate Levels Using Standardized Ethanol Content.

Importance: Differences have been observed in the association of serum urate levels with consumption of different types of alcoholic beverages. However, previous studies have not standardized the unit of intake for ethanol content, and only limited types of alcoholic beverages have been evaluated. Objective: To examine differences in the association of serum urate levels with various types of alcoholic beverages when their intakes are standardized for ethanol content. Design, Setting, and Participants: This retrospective cross-sectional study was conducted using data from participants aged 20 years or older who completed a medical checkup at St Luke's International University in Japan between October 1, 2012, and October 31, 2021. Participant demographics, blood test results, and lifestyle questionnaire data were used as covariates. Analysis was performed in December 2021. Exposures: Consumption of alcoholic beverages, including beer, sake (rice wine), shochu (Japanese spirit), wine, and whiskey. Main Outcomes and Measures: Serum urate levels were measured during the medical checkup. The beverage unit was standardized to 1 standard drink, which contained 20 g of ethanol. Multivariable linear regression including interaction terms of alcohol consumption and dominant alcoholic beverage was performed. Results: This study included 78 153 participants. Their mean (SD) age was 47.6 (12.8) years; 36 463 (46.7%) were men and 41 690 were women (53.3%). A total of 45 755 participants (58.5%) were regular alcohol drinkers. Consistent associations of serum urate levels with alcohol consumption were observed in the beer-dominant group, with ß coefficients (for 1 standard drink per day) of 0.14 mg/dL (95% CI, 0.11-0.17 mg/dL; P < .001) for men and 0.23 mg/dL (95% CI, 0.20-0.26 mg/dL; P < .001) for women. A moderate increase in serum urate levels was observed in the wine-dominant group compared with a modest and nonsignificant increase in the sake-dominant group, with ß coefficients (for 1 standard drink per day) for the latter group of 0.05 mg/dL (95% CI, -0.01 to 0.10; P = .10) for men and 0.04 mg/dL (95% CI, -0.05 to 0.14 mg/dL; P = .38) for women. Restricted cubic splines showed different patterns in associations of serum urate levels with ethanol intake by dominant alcoholic beverages. Conclusions and Relevance: The results of this study suggest that the extent of the association of serum urate levels with alcohol intake was different for alcoholic beverages even after ethanol content was standardized. Higher beer consumption among men and women was consistently associated with higher serum urate levels, whereas sake was not associated with changes in serum urate levels. Therefore, alcoholic beverage type, in addition to ethanol content, should be considered as a factor contributing to hyperuricemia.

Safety of tacrolimus use during pregnancy and related pregnancy outcomes in patients with systemic lupus erythematosus: A retrospective single-center analysis in Japan.

OBJECTIVE: Tacrolimus is one of the drugs that can be used in pregnancies complicated with systemic lupus erythematosus (SLE), but there are still few reports on its pregnancy outcomes. Although tacrolimus has been reported to cause adverse events, such as increased blood pressure, abnormal glucose metabolism, and susceptibility to infection, there have been no studies on the impact of tacrolimus in SLE pregnancies at these points. We performed a retrospective observational study of pregnancies complicated by SLE at St Luke's International Hospital in Tokyo from April 2003 to August 2021. METHODS: Basic clinical information on SLE, pregnancy outcomes, disease activity before and after pregnancy, laboratory results, blood pressure, blood glucose levels, treatment regimens, and presence of infection was extracted from electronic medical records. We defined overall adverse pregnancy outcomes (APOs) as follows: (1) fetal death after 10 gestational weeks, (2) preterm delivery, (3) delivery due to hypertensive disorders of pregnancy, preeclampsia, or placental insufficiency, or (4) the diagnosis of small for gestational age infants. We also examined whether there was a statistical difference in APO incidence between patients treated with and without tacrolimus. RESULTS: Pregnancy outcomes were obtained for 48 patients with a total of 60 pregnancies complicated by SLE. In 20 (33.3%) of these pregnancies, the patients took tacrolimus, and 28 (46.7%) of the pregnancies had APOs. APO incidence did not statistically differ between the tacrolimus and non-tacrolimus groups in the multivariate analysis (p = 1.00, adjusted OR 1, 95% CI: 0.23-4.39). Multiple regression analyses indicated that tacrolimus use did not significantly affect systolic blood pressure in the third trimester (B = -2.23, p = .74) or blood glucose levels in the first trimester (B = 10.2, p = .056). Incidence of infections did not significantly differ between patients treated with and without tacrolimus in the univariate analysis (10.8% vs. 21.1%, p = .42). CONCLUSION: Tacrolimus did not significantly affect pregnancy outcomes, blood pressure, or glucose levels. Further research is required to confirm its effects in a larger population.

A case report of two systemic lupus erythematosus pregnancies with early placental exposure to belimumab: Case report with review.

Since its approval for the management of systemic lupus erythematosus (SLE), belimumab has been widely used. However, its pregnancy safety profile has been underinvestigated. We present the pregnancy outcomes of two cases of early placental exposure to belimumab and summarise the pregnancy outcomes in previous reports regarding placental exposure to belimumab. Case 1 describes a 27-year-old woman with an 18-year history of SLE and lupus nephritis class III. We introduced belimumab 19 months prior to conception to control her proteinuria and discontinued its use at 5 weeks and 5 days of gestation. Her lupus activity was stable throughout pregnancy, and at 37 weeks and 1 day of gestation, she delivered a healthy girl with no anomaly. At delivery, the girl was small for gestational age, but at the 1-year follow-up, there was no delay in her growth or any serious infection. Case 2 describes a 32-year-old woman with a 15-year history of SLE. We introduced belimumab 9 months prior to conception and discontinued its use at 7 weeks and 1 day of gestation. Although her lupus was well controlled without belimumab, a missed abortion occurred, which was possibly due to foetal factors. Although there is accumulating data on the safety of belimumab use during pregnancy, it seems necessary to cautiously use this medication in pregnant women, until further analyses are conducted.

Advantages of an alternate-day glucocorticoid treatment strategy for the treatment of IgG4-related disease: A preliminary retrospective cohort study.

Alternate-day glucocorticoid (GC) therapy is a treatment option that can reduce GC-associated adverse events. We investigated the safety and efficacy of alternate-day GC therapy in patients with immunoglobulin G4-related disease (IgG4-RD). Medical records of patients with IgG4-RD who were followed for at least one year at St. Luke's International Hospital, Tokyo, Japan, from 2004 to 2020 were reviewed. Patients who fulfilled comprehensive IgG4-RD diagnostic criteria were divided into alternate-day or daily GC treatment groups based on their treatment protocol. The effect of alternate-day GC therapy on glucocorticoid toxicity index (GTI) score was evaluated using multilinear analysis with adjustments for cumulative GC doses until each assessment point and propensity scores (PS) for alternate-day GC therapy. Kaplan-Meier curves and Cox proportional hazard models were used to assess the efficacy of alternate-day GC therapy for disease control. Among the 67 patients with IgG4-RD, patients with alternate-day (n = 13) and daily (n = 31) GC treatments were analyzed after excluding 23 ineligible patients. The median (interquartile range) age was 64 (60-70) years, 29 (65.9%) were male patients, 26 (59.1%) patients had positive biopsy results, and the median follow-up period was 1643 days. Significantly more patients with alternate-day GC treatment used concomitant immunosuppressants (11 [84.6%] vs 11 [35.5%]; P = .007). The alternate-day strategy significantly lowered the GTI score after adjusting for cumulative GC dose until the assessment and PS (adjusted coefficient: -29.5 [-54.3, -4.8], P = .021 at 12 months; -20.0 [-39.8, -0.1], P = .049 at 24 months). Serious infections were numerically less frequent in the alternate-day group (incidence ratio [95% confidence interval [CI]: 0.45 [0.05, 3.63], P = .45). Most patients (92.3%) in the alternate-day GC treatment group and all patients in the daily GC treatment group showed treatment responses in the remission induction therapy. The PS-adjusted hazard ratio of alternate-day GC treatment for disease flares was not significant (1.55 [0.53, 4.51]; P = .43). The alternate-day treatment strategy significantly reduced GC-related adverse events regardless of the cumulative GC dose. Alternate-day GC treatment is a feasible option for patients with IgG4-RD, without a significant increase in disease flares particularly when combined with immunosuppressants.

Effect and safety profile of belimumab and tacrolimus combination therapy in thirty-three patients with systemic lupus erythematosus.

INTRODUCTION/OBJECTIVES: Belimumab combined with mycophenolate mofetil has been proven to be effective for treating systemic lupus erythematosus (SLE) in several randomized controlled trials. Calcineurin inhibitors are also useful in controlling the activity of SLE. However, the safety and effectiveness of belimumab-calcineurin inhibitor combination therapy have not been addressed. Therefore, the current single-center retrospective study aimed to analyze the safety/efficacy profile of belimumab-tacrolimus (B-T) combination therapy in patients with SLE. METHOD: Patients with SLE administered tacrolimus and belimumab during treatment were included in the study. Samples were analyzed for the drug retention rate, SLE flare rate, infection incidence rate, and glucocorticoid-sparing effect of the B-T combination therapy. RESULTS: Thirty-three patients with SLE were treated with B-T combination therapy at our institution. Four patients discontinued treatment due to insufficient response or adverse events. The drug retention rate was over 90% at week 52 and approximately 80% at day 1000. Only one patient developed serious infection. The lupus low disease activity state (LLDAS) achievement ratio was 9.1% on the day of initiation and improved to 64.0% at 52 weeks after initiation. SLE flares were observed in three patients (9.1%) in the first 52 weeks after initiation, and in five patients (15.2%) throughout the study period. A glucocorticoid-reducing effect was also observed in patients treated with B-T combination therapy. CONCLUSIONS: In most patients with SLE, B-T combination therapy is well tolerated with a good efficacy profile and glucocorticoid-reducing effect. Thus, B-T combination therapy represents a feasible option for patients with refractory lupus. Key Points • The safety and effectiveness of belimumab-calcineurin inhibitor combination therapy have not been addressed. • The drug retention rate of belimumab-tacrolimus combination therapy was over 90% at week 52 and around 80% on day 1000 • Almost none of the patients suffered from severe infection after the initiation of belimumab-tacrolimus combination therapy. • Belimumab-tacrolimus combination therapy is efficacious in suppressing lupus activity and achieving LLDAS.

Glucocorticoid discontinuation in patients with SLE with prior severe organ involvement: a single-center retrospective analysis.

OBJECTIVE: Long-term glucocorticoid use in SLE may have significant side effects; however, glucocorticoid discontinuation is occasionally associated with disease flare-ups. Therefore, we evaluated the risk factors for disease flares and the flare rate on glucocorticoid tapering in patients with prior severe organ involvement. METHODS: Data of patients with SLE with glucocorticoid tapering at our institution were retrospectively analysed. We divided the patients by the presence of prior severe organ involvement and compared flare rates after glucocorticoid discontinuation. Furthermore, we determined risk factors for flares after glucocorticoid discontinuation. RESULTS: In total, 309 patients with SLE were screened, 73 of whom met the inclusion criteria; 49 were classified as SLE with prior severe organ involvement. No significant differences were noted in the 52-week flare rate after glucocorticoid discontinuation between patients with and without prior severe organ involvement (16.7% vs 18.2%, p=1.0). Hypocomplementaemia, elevated anti-dsDNA antibody titres more than twice the upper limit of the laboratory reference range, positive anti-Smith/anti-ribonucleoprotein antibody, and use of any immunosuppressant on the day of glucocorticoid discontinuation were negatively associated with flare-free remission. CONCLUSIONS: Glucocorticoid discontinuation after gradual tapering can often be achieved in patients with SLE, even with prior severe organ involvement, especially when the disease is clinically and serologically stable.

Image quality and radiologists' subjective acceptance using model-based iterative and deep learning reconstructions as adjuncts to ultrahigh-resolution CT in low-dose contrast-enhanced abdominopelvic CT: phantom and clinical pilot studies.

PURPOSE: In contrast-enhanced abdominopelvic CT (CE-APCT) for oncologic follow-up, ultrahigh-resolution CT (UHRCT) may improve depiction of fine lesions and low-dose scans are desirable for minimizing the potential adverse effects by ionizing radiation. We compared image quality and radiologists' acceptance of model-based iterative (MBIR) and deep learning (DLR) reconstructions of low-dose CE-APCT by UHRCT. METHODS: Using our high-resolution (matrix size: 1024) and low-dose (tube voltage 100 kV; noise index: 20-40 HU) protocol, we scanned phantoms to compare the modulation transfer function and noise power spectrum between MBIR and DLR and assessed findings in 36 consecutive patients who underwent CE-APCT (noise index: 35 HU; mean CTDIvol: 4.2 ± 1.6 mGy) by UHRCT. We used paired t-test to compare objective noise and contrast-to-noise ratio (CNR) and Wilcoxon signed-rank test to compare radiologists' subjective acceptance regarding noise, image texture and appearance, and diagnostic confidence between MBIR and DLR using our routine protocol (matrix size: 512; tube voltage: 120 kV; noise index: 15 HU) for reference. RESULTS: Phantom studies demonstrated higher spatial resolution and lower low-frequency noise by DLR than MBIR at equal doses. Clinical studies indicated significantly worse objective noise, CNR, and subjective noise by DLR than MBIR, but other subjective characteristics were better (P < 0.001 for all). Compared with the routine protocol, subjective noise was similar or better by DLR, and other subjective characteristics were similar or worse by MBIR. CONCLUSION: Image quality, except regarding noise characteristics, and acceptance by radiologists were better by DLR than MBIR in low-dose CE-APCT by UHRCT.

Risk of adverse pregnancy outcomes in Japanese systemic lupus erythematosus patients with prior severe organ manifestations: A single-center retrospective analysis.

BACKGROUND: Systemic lupus erythematosus (SLE) increases the incidence of adverse pregnancy outcomes (APOs). Nevertheless, most of the data on SLE pregnancies were derived from database studies in which details of the pregnancies were unavailable, and no consensus exists on the risk of APO in patients with prior severe organ manifestations. METHODS: SLE patients followed by rheumatologists and gynecologists throughout pregnancy at our institute were retrospectively identified, and their data between April 2003 and December 2020 were reviewed from electronic records. We assigned patients based on the presence of prior severe organ manifestation (renal/neurological manifestation, prior treatment with methylprednisolone pulse therapy/prednisolone 1 mg/kg/day/biological or cytotoxic therapy) and compared the incidence of overall and serious APO (maternal death, pregnancy loss, preterm birth <32 weeks, birthweight <1500 g, Apgar score <7 at 5 min and birth defect). RESULTS: This study included 34 pregnancies in 32 patients; 23 pregnancies in 22 patients were classified as SLE with prior severe organ manifestation. There was no statistical difference in the incidence of overall APO between the two groups (52.2% vs 45.5%, P = 1). Among patients with prior severe organ manifestation, 17.4% had serious APO. A detailed electronic health record search revealed specific causes of APO in all pregnancies with serious APO, except the presence of prior severe organ manifestation. CONCLUSION: The incidence of overall APO in SLE patients was not affected by prior severe organ manifestation. Although the incidence of serious APOs increased in patients with previous severe organ manifestation, there were other risk factors for poor pregnancy outcomes besides prior lupus severity. Therefore, proper management by rheumatologists and gynecologists may enable patients with prior severe organ manifestation to safely deliver healthy babies.

Effectiveness and safety of mizoribine for the treatment of IgG4-related disease: a retrospective cohort study.

OBJECTIVE: Patients with IgG4-related disease (IgG4RD) usually require steroid-sparing agents due to relapse with tapering glucocorticoids (GC). We aimed to determine the efficacy and safety of mizoribine (MZR) among IgG4RD patients. METHODS: We retrospectively reviewed records of IgG4RD patients at Immuno-Rheumatology Center in St. Luke's International Hospital, Tokyo, Japan. Patients treated with MZR were classified into the MZR group, and those treated with GC alone or with other immunosuppressants were included in the control group. Disease exacerbation, GC dose, IgG-IgG4 titre and adverse events were evaluated using univariate analyses, including the Kaplan-Meier method. The Cox proportional hazard model was used to evaluate risk factors for disease exacerbation. RESULTS: A total of 14 and 29 cases were included in the MZR and control group. Multiple organ involvement (three or more organs) was significantly more frequent in the MZR group [10 (71.4%) vs 9 (31.0%), P= 0.021]. Kaplan-Meier analysis revealed a significant reduction inexacerbation in patients with multiple organ involvement (P< 0.001) but not in total (P= 0.42). The adjusted hazard ratios of MZR use and multiple organ involvement for exacerbation were 0.34 (95%CI 0.12-1.01; P = 0.052) and 3.51 (95%CI 1.29-9.51; P= 0.014). The cumulative GC dose (mg per year, interquartile range) tended to be lower in the MZR group [1448 (1003-1642) vs 2179 (1264-3425); P= 0.09]. CONCLUSION: MZR decreased disease exacerbation among IgG4RD patients with multi-organ involvement and showed a steroid-sparing effect. MZR could be a treatment option for IgG4RD.

Potential and prognostic factor for belimumab-free remission in patients with systemic lupus erythematosus: a single-center retrospective analysis.

Belimumab is an effective and safe treatment option for systemic lupus erythematosus (SLE). However, data on treatment cessation are lacking. Thus, we investigated belimumab-free remission in SLE patients. SLE patients receiving belimumab in our institute (May 1, 2013-May 31, 2019) were retrospectively identified using electronic health records. Eligibility criteria included receiving belimumab for > 180 days and discontinuation for any reason. BILAG category A or B in at least one organ system indicated a disease flare. Follow-up monitoring during post-treatment at week 52 identified relapse-free and relapse patients. Thirty-one patients received belimumab, and 8 patients were included. Of the 8 patients, 4 relapsed within 52 weeks. At belimumab discontinuation, relapse-free patients achieved lower SELENA-SLEDAI (1 [IQR, 0-2] vs. 7 [IQR, 5.5-8] (p = 0.03)), received significantly less steroid (prednisolone equivalent, 3.0 mg/day [IQR, 2.8-3.2] vs. 9.5 mg/day [IQR, 7.3-13.3], p = 0.02) than relapse patients, and significantly more relapse-free patients achieved SELENA-SLEDAI less than 4 and received prednisolone less than 5 mg/day than relapse patients. Furthermore, on discontinuation day, relapse-free patients tended to have higher C3 (91.0 mg/dL [IQR, 78.8-102.3] vs. 56.0 mg/dL [IQR, 39.8-73.0], p = 0.15) and C4 levels (22.0 mg/dL [IQR, 19.00-26.00] vs. 11.0 mg/dL [IQR, 6.00-16.00], p = 0.08) and less anti-dsDNA antibody (5.2 IU/mL [IQR, 3.8-7.8] vs. 48.0 IU/mL [IQR, 11.5-137.3], p = 0.08) than relapse patients. Belimumab discontinuation can be considered for patients who achieved good responses. Normalization of complement, anti-dsDNA antibody, SELENA-SLEDAI less than 4, and steroid dosage less than 5 mg/day might be prognostic markers for belimumab-free remission.

Endogenous endophthalmitis caused by Streptococcus agalactiae: An ophthalmologic emergency.

Here, we present a 76-year-old diabetic man who was diagnosed as having endogenous endophthalmitis caused by Streptococcus agalactiae that finally developed globe rupture, which is a rare endogenous endophthalmitis complication. This case highlight that endogenous endophthalmitis is an ophthalmological emergency with poor prognosis, thereby requiring prompt diagnosis and aggressive intervention.

Nonhepatocytic malignant mixed tumor of the liver in adults: report of a long surviving case.

A primary nonhepatocytic malignant mixed tumor in the liver contains both epithelial and mesenchymal components, and the incidence in adults is extremely rare. A 45-year-old female was admitted because of abdominal fullness. Abdominal imaging studies revealed a huge cystic tumor with a mural nodule in the right lobe. A right trisegmentectomy and an invaded partial diaphragm resection were performed. Diagnosis was established after surgery. The patient is still alive 11 years after surgery, and to our knowledge is the longest surviving patient with a primary nonhepatocytic malignant mixed primary tumor of the liver.

A case of isolated pancreatic metastasis of gastric cancer presenting problematic discrimination from gastropancreatic double cancer.

We experienced a case of isolated pancreatic metastasis caused by gastric cancer which showed high levels of the tumor markers relevant to pancreatic cancer. The patient was a 59-year-old man who had tumors in both the gastric antrum and pancreatic head. He was diagnosed as having double cancer of the stomach and pancreas on account of the high values of pancreatic cancer-associated markers, and underwent operation. This resulted in non-curable resection attributable to broad lymph node metastasis. The resected specimen lacked continuity between the pancreas tumor and gastric tumor, and the pancreatic tumor was histologically diagnosed as metastasis from the gastric cancer. Moreover, the advanced lymph vessel invasion suggested possible metastasis through the lymph ducts. The present case is a rare metastatic form because there has been no report of lymphogenous isolated pancreatic metastasis of gastric cancer. In advanced gastric cancer, the possibility of pancreatic metastasis should be always borne in mind, and pancreatic biopsy may be taken into account at times. Radical operation may be performed corresponding to the degree of each stage of the double cancer of stomach and pancreas. However, considering the low possibility of curable resection for pancreatic metastasis of gastric cancer, other treatments than surgery should also be considered.

Indications for extended hepatectomy in the management of stage IV hilar cholangiocarcinoma.

HYPOTHESIS: In operations for hilar cholangiocarcinoma, simultaneous extended hepatectomy and removal of extrahepatic bile ducts are considered curative resection. However, the effect of extended operations for stage IV hilar cholangiocarcinoma on survival is still unclear. DESIGN: Retrospective review of the treatment of hilar cholangiocarcinoma from 1981 to 2001. PATIENTS AND METHODS: Fifty-seven patients with stage IVA or IVB hilar cholangiocarcinoma were enrolled. Thirty-three of these patients underwent extended hepatectomy to achieve macroscopic radical resection (surgical group). A self-expandable metallic biliary stent (EMBS) was implanted in 24 patients (EMBS group) in whom radical treatment was judged to be impossible. Main Outcome Measure Survival in patients with stage IV hilar cholangiocarcinoma treated by means of extended operation or stenting. RESULTS: Survival was 25.7 +/- 40.9 months in the surgical group vs 6.5 +/- 5.8 months in the EMBS group (P =.03). In the surgical group, radical resection results were macroscopically and histologically successful in 21 patients (64%). In patients with stage IVB disease, survival did not differ between the surgical and EMBS groups. CONCLUSIONS: In patients with stage IVA disease, radical extended hepatectomy should be performed after excluding patients who have extensive invasion of the hepatic artery or portal vein. However, in patients with stage IVB disease with carcinomatous peritonitis or distant metastasis, there is little possibility of achieving long-term survival with surgery, and stent implantation should be the first choice.

Fructose-1,6-Bisphosphate inhibits excess activation of Kupffer cell function induced by endotoxin.

The effect and mechanism of action of fructose-1,6-bisphosphate (FBP) on Kupffer cell activation were studied in vitro. Kupffer cell was activated by isolation procedure alone from the hepatic tissue. In cultured rat Kupffer cells stimulated by endotoxin, treatment with 5-20 mM FBP not only preserved phagocytic activity, but also inhibited secretion of cytokines (tumor necrosis factor-a and interleukin-1beta) and production of nitric oxide (NOx). Moreover, treatment with 10 mM FBP suppressed the elevation in the intracellular Ca2+ concentration on Kupffer cells stimulated by phorbol 12-myristate 13-acetate, which suggested that this effect may be one of the agents that limit the activation of Kupffer cells. The administration of FBP was effective in the prevention of endotoxin-induced hepatopathy, and we suggest that this may have useful clinical applications.
