Significant improvement of bone mineral density by denosumab without bisphosphonate pre-treatment in glucocorticoid-induced osteoporosis

Objective: The aim of this study was to evaluate differences in outcomes of denosumab for a year with or without bisphosphonate (BP) pre-treatment in patients with glucocorticoid-induced osteoporosis (GIO).

Methods: Forty-eight female patients with GIO and low bone mineral density (BMD) (T score of BMD; less than ?3.0 SD) were, retrospectively, enrolled and classified into the following two groups: (1) GIO with BP pre-treatment (BP pre-treated group; n?=?24) and (2) GIO without BP treatment (BP pre-untreated group; n?=?24). We measured serum bone alkaline phosphatase (BAP), N-terminal propeptide of type 1 procollagen (P1NP), and tartrate-resistant acid phosphatase (TRACP)-5b at baseline, and at 3, 6, and 12 months. We also assessed BMD of the lumbar 1–4 vertebrae BMD (L-BMD) and bilateral hip BMD (H-BMD) at baseline, and at 6 and 12 months.

Results: TRACP-5b was significantly inhibited at 3 months in both groups and at 6 and 12 months in the BP pre-untreated group compared with pre-treatment levels. Both BAP and P1NP were significantly suppressed at 3, 6, and 12 months in both groups compared with baseline values. L-BMD and H-BMD were significantly increased at 6 (4.2% and 3.4%, respectively) and 12 months (4.7% and 4.7%, respectively) in the BP pre-untreated group over pre-treatment levels. There were no significant differences between the groups during the observational period.

Conclusion: Denosumab significantly improved both L-BMD and H-BMD in the BP pre-untreated group, but not in the BP pre-treated group, suggesting it to be a good option for GIO patients without BP pre-treatment.     

Short-term daily teriparatide in patients with rheumatoid arthritis

Objective: The aim of this study was to compare the efficacy of six-month teriparatide treatment followed by six-month bisphosphonate therapy with 12-month bisphosphonate monotherapy in Japanese rheumatoid arthritis (RA) patients who had not been previously treated for osteoporosis.

Methods: A total of 34 RA patients with osteoporosis were enrolled. Thirteen patients received six-month teriparatide prior to six-month minodronate therapy (PTH group), and 21 patients received 12-month minodronate therapy (BP group). Bone mineral density (BMD), and bone turnover markers were measured prior to and 6 and 12 months after the initiation of treatment.

Results: Bone mineral density of the spine was significantly increased after 12 months of treatment in both groups. In the PTH group, the mean percent change of BMD of the spine was significantly higher at 12 months after the initiation of treatment, as compared to the BP group (PTH group: 9.9?±?1.5%, BP group: 5.5?±?0.7%). Femoral neck BMD was significantly increased only in the PTH group after 12 months.

Conclusion: Therapy involving six-month teriparatide followed by six-month minodronate therapy increased spine BMD to a greater degree than 12-month minodronate monotherapy. The strategy of short-term administration of teriparatide for RA patients with osteoporosis might be useful when additional bisphosphonate therapy is considered.     

Comparison of the efficacy of denosumab and bisphosphonates for treating secondary osteoporosis in patients with rheumatoid arthritis

Objectives: This study aimed to investigate the efficacy of denosumab (compared with that of bisphosphonates) for preventing secondary osteoporosis and inflammation caused by excessive bone resorption in Japanese rheumatoid arthritis (RA) patients never previously treated for osteoporosis.

Methods: Ninety-eight patients with coexisting RA and osteoporosis were enrolled. The patients were subdivided by whether they were treated with denosumab (n?=?49) or traditional bisphosphonates (n?=?49). RA disease activity, bone turnover markers, and bone mineral density (BMD) were compared between the two groups before treatment, and after 6 and 12 months of treatment.

Results: There was no significant difference between the groups in any of the disease activity indices and BMD at any of the measured time points. With regard to bone metabolism, denosumab significantly reduced bone-specific alkaline phosphatase at 6 and 12 months compared with pretreatment, but had no effect on tartrate-resistant acid phosphatase 5b levels, suggesting an effect on the bone formation rate, but not on the bone resorption rate.

Conclusions: Neither denosumab nor bisphosphonates could suppress inflammation or RA disease activity, but denosumab significantly suppressed a marker of bone metabolism in Japanese RA patients never previously treated for osteoporosis.     

Effects of alendronate or alfacalcidol on bone metabolic indices and bone mineral density in patients with ophthalmologic disease treated with glucocorticoid

Abstract

Objectives. Glucocorticoid (GC) is usually used for the treatment of systemic inflammatory diseases. We performed the prospective study to clarify the effects of alendronate or alfacalcidol on bone metabolic indices and bone mineral density (BMD) in 90 patients treated with GC for ophthalmologic diseases without systemic disorders for 12 months.

Methods. BMD was measured with dual-energy X-ray absorptiometry. Serum bone-specific alkaline phosphatase (BAP) and urinary Type I collagen cross-linked N-telopeptide (NTx) were measured as bone metabolic indices.

Results. BMD values in the alendronate group were significantly higher than those in the alfacalcidol group during 12 months. Alendronate significantly reduced urinary NTX levels from the baseline during 12 months, although alfacalcidol did not affect them. Serum BAP levels in the alendronate group were significantly lower than those in the alfacalcidol group during 9 months. The effects of alendronate on BMD and NTx in male patients seemed to be somewhat potent compared with those in female patients.

Conclusions. Alendronate is effective to prevent BMD loss and bone resorption induced by GC treatment in patients with ophthalmic diseases without systemic disorders. There might be sex differences in the potency of alendronate effects.     

Denosumab did not improve computerized tomography erosion scores when added to intensive urate-lowering therapy in gout: Results from a pilot randomized controlled trial

Background/PurposeDisordered osteoclast activity has been implicated in the pathogenesis of gouty bone erosion. We sought to determine if the addition of denosumab (a monoclonal antibody targeting the receptor activator of nuclear factor kappa-B ligand - RANKL) to intensive urate-lowering therapy (ULT) improves gouty bone erosion.MethodsOpen-label, parallel-group pilot randomized controlled trial in which 20 participants with gout with at least one confirmed conventional radiographic foot bone erosion were assigned in a 1:1 allocation to receive denosumab (60 mg subcutaneous every 6 months) added to intensive ULT (serum urate ≤5 mg/dL or 300 µmol/L at the time of randomization and continued for the duration of the study), or intensive ULT alone. The primary outcome was the change in the bilateral foot and ankle computed tomography (CT) bone erosion score from baseline to 12 months, assessed by an experienced musculoskeletal radiologist blinded to study assignment. Secondary outcomes included change in serum C-terminal telopeptide (CTX), and patient reported outcomes of pain and function.ResultsAlthough serum CTX declined markedly in the denosumab/ULT group compared with the ULT alone group, there was no interval change in CT erosion score in either the denosumab/ULT or ULT alone group after one year of follow-up. Other secondary outcomes did not differ between groups. There were two severe adverse events: One patient developed atrial fibrillation (on denosumab/ULT) and another atrial flutter (on ULT alone).ConclusionsIn this pilot study, denosumab did not offer additional benefit to intensive urate lowering therapy for gouty bone erosion.     

Long-term clinical outcome after infliximab discontinuation in patients with inflammatory bowel disease

Abstract

Objectives: We investigated the long-term clinical outcome and risk factors for clinical relapse in inflammatory bowel disease (IBD) patients after stopping infliximab (IFX).

Materials and methods: We retrospectively reviewed the medical records of IBD patients who were treated with IFX in four university hospitals in South Korea. Among them, patients who discontinued scheduled IFX therapy with a favorable disease course were enrolled. Clinical relapse was defined as an increase in disease activity, addition of new drugs, or abdominal surgery.

Results: In total, 28 ulcerative colitis (UC) patients and 17 Crohn’s disease (CD) patients were enrolled. The median duration of follow-up after discontinuation was 41 months (range: 8–109 months) in UC patients and 141 months (range: 66–262 months) in CD patients. The cumulative probability of relapse at 12 months was 32.1% in UC patients and 30.7% in CD patients. Fewer IFX infusions and a shorter duration of mesalamine treatment after IFX discontinuation were risk factors for relapse after IFX discontinuation in UC patients (p?=?.04 and .01, respectively). In CD patients, a higher erythrocyte sedimentation rate and CRP at IFX discontinuation and a shorter duration of azathioprine treatment after IFX discontinuation were risk factors for relapse (p?=?.03, .03 and .01, respectively).

Conclusions: Approximately 30% of IBD patients who responded to IFX therapy experienced relapse within 1 year after discontinuation. We identified several risk factors for relapse. Further studies should identify factors predictive of the disease course after discontinuing IFX maintenance therapy.     

The effect of methotrexate on bone metabolism markers in patients with rheumatoid arthritis

Abstract

The aim of the present study was to evaluate the influence on urinary excretion levels of N-telopeptide of type I collagen (NTX) and deoxypyridinoline (DPD) as a useful marker for bone resorption, and on serum-bone alkaline phosphate (BAP) levels as a useful marker for bone formation and an early marker of osteoblast differentiation in patients with rheumatoid arthritis (RA) treated with methotrexate (MTX). Thirty patients with RA, diagnosed according to the criteria of the American College of Rheumatology, were involved in this study between March 2003 and January 2005. None of the patients had a history of hormone (estrogen) replacement therapy. All patients were treated with MTX. Methotrexate was administered perorally at a dosage of 4–10?mg/week. All patients underwent general and physical examinations and routine blood and urinary analysis at the baseline, 3 months and 6 months after the initial treatment. Then the levels of NTX and DPD in urine and BAP in serum were measured in all patients. For comparison with the effect of other DMARDs on bone metabolism markers in RA patients, we measured the levels of NTX and DPD in urine and BAP in serum of RA patients, 13 patients treated with salazosulfapyridine (SASP), and 14 patients treated with actarit (ACT). In patients treated with MTX, NTX levels decreased significantly at 3 months after the initial treatment and remained low at 6 months after the initial treatment, and DPD levels significantly decreased at 6 months after the initial treatment. The mean serum BAP levels changed without significant differences from the baseline at 3 months and 6 months. In patients treated with SASP and ACT, all bone metabolism markers had not changed significantly at the three time points. On disease activity erythrocyte sedimentation rate, C-reactive protein, the number of swollen joints and tender joints, and mHAQ score decreased significantly at 3 months after the initial treatment, and remained at low levels at 6 months after the initial treatment with MTX. Methotrexate therapy looks promising in inhibiting generalized bone loss in patients with RA. In addition, NTX is a more sensitive marker than DPD.     

Comparison of the effects of denosumab with either active vitamin D or native vitamin D on bone mineral density and bone turnover markers in postmenopausal osteoporosis

Osteoporosis is a worldwide health concern. Although treatment with denosumab plus the active vitamin D alfacalcidol has been found to improve femoral neck (FN) and distal forearm bone mineral density (BMD), there have been no reports on the efficacy or adverse effects of denosumab plus eldecalcitol (ELD) in primary osteoporosis patients. Fifty-six treatment-naïve post-menopausal women with primary osteoporosis were recruited and divided into denosumab plus native vitamin D or denosumab plus ELD. Ultimately, 26 subjects in the native vitamin D group and 24 in the ELD group were analyzed. Lumbar and total hip BMD significantly increased in both groups. However, there was no significant difference in the percent increase of lumbar and total hip BMD between two groups. FN-BMD was significantly increased from 6 to 12 months in the ELD group compared with baseline. This study revealed that combination therapy with denosumab and ELD could improve FN-BMD more effectively than denosumab plus native vitamin D. Thus, the addition of ELD may enhance the effects of denosumab treatment for primary osteoporosis.     

Improved real-life adherence of 6-monthly denosumab injections due to positive feedback based on rapid 6-month BMD increase and good safety profile

Almost 50 % of osteoporosis (OP) patients discontinue bisphosphonate (BP) therapy within 1–2 years after the start of their treatment. Denosumab’s longer dosing interval with its administration every 6 months (Q6M) as a subcutaneous (sc) injection might result in a better real-life treatment adherence and persistence than weekly or monthly oral BP treatment regimen. The objectives of this open, investigator-initiated, prospective, observational, single-center study were to evaluate adherence with denosumab 60 mg sc every 6 months (Q6M) (Prolia^®) injections in osteoporotic patients in a routine clinical care setting and to describe whether positive feedback to OP patients based on measured bone mineral density (BMD) increases and good safety profile have an impact on patients’ real-life adherence. Results indicate that the rarity of adverse events and reduced dosage frequency together with the consistency of rapid and highly significant increases in BMD already after 6 months of denosumab therapy used as a positive reinforcement during doctor–patient interactions had a significant, positive impact on osteoporotic patient’s adherence to continue with the 6-monthly sc denosumab injections.     

Clinical results of alendronate monotherapy and combined therapy with menatetrenone (VitK2) in postmenopausal RA patients

Objectives

We aimed to evaluate the clinical efficacy of monotherapy with alendronate and combined therapy with alendronate and menatetrenone (vitamin K2 [VitK2]) in postmenopausal rheumatoid arthritis (RA) patients with osteoporosis or osteopenia.

Methods

Sixty-two postmenopausal RA patients with untreated osteoporosis or osteopenia (lumbar spine bone density ≤80 % of young adult mean [YAM]) were enrolled: 39 had abnormal serum undercarboxylated osteocalcin (ucOC) levels (>4.5 ng/mL) and received combined therapy with alendronate (35 mg/week) and VitK₂ (45 mg/day) (ALN + K group); 23 had normal ucOC levels (≤4.5 ng/mL) and received alendronate monotherapy (35 mg/week) (ALN group). The clinical results for the 57 patients in both groups were evaluated after 1-year treatment.

Results

The mean baseline/follow-up (FU) lumbar spine bone density (%YAM) values were 73.0/76.8 % (P < 0.01) in the ALN + K group and 77.0/80.3 % (P < 0.01) in the ALN group; a significant increase was shown in both groups. Mean proximal femoral bone density values at baseline/FU were 71.4/73.8 (P < 0.01) in the ALN + K group and 71.4/71.6 % (not significant; NS) in the ALN group; a significant increase was shown in the ALN + K group only. Serum ucOC levels were normalized in the ALN + K group at FU. At FU, bone metabolism markers [bone-specific alkaline phosphatase (BAP) and N-terminal cross-linked telopeptides of type I collagen] were decreased in both groups. One patient in the ALN + K group and three in the ALN group suffered new fractures.

Conclusions

Combined therapy with alendronate and VitK₂ decreases bone metabolism marker levels and serum ucOC levels, and increases lumbar spine and femoral neck bone density in postmenopausal RA patients with abnormal ucOC levels and osteoporosis or osteopenia.     

Effects of teriparatide, alendronate, or both on bone turnover in osteoporotic men

CONTEXT: We have previously demonstrated that alendronate reduces the ability of teriparatide to increase bone mineral density (BMD) in osteoporotic men. The underlying basis for this observation is poorly understood. OBJECTIVE: The primary aim of this study was to determine whether teriparatide increases osteoblast activity when the ability of teriparatide to increase osteoclast activity is suppressed by alendronate. DESIGN: This was a nonblinded, randomized, controlled trial. SETTING: The study was conducted at the General Clinical Research Center of a teaching hospital. PATIENTS: We studied 63 men, age 46-85, with low spine and/or hip BMD. INTERVENTIONS: Subjects received alendronate 10 mg daily (group 1), teriparatide 37 microg sc daily (group 2), or both (group 3) for 30 months. Teriparatide was begun at month 6. MAIN OUTCOME MEASURES: The primary endpoint was the change in serum N-telopeptide, osteocalcin, and amino-terminal propeptide of type 1 procollagen. RESULTS: In men receiving teriparatide monotherapy (group 2), levels of all bone turnover markers increased markedly during the first 6 months of teriparatide administration and then declined toward baseline during the next 18 months. In men who received combination therapy (group 3), bone turnover marker levels declined in the first 6 months (while receiving alendronate alone) and then returned to baseline levels (N-telopeptide) or above (osteocalcin and amino-terminal propeptide of type 1 procollagen) after teriparatide was added. Changes in each marker were significantly different between groups 1 and 2 (all P values < 0.001), groups 1 and 3 (all P values < 0.001), and groups 2 and 3 (all P values < 0.03). CONCLUSIONS: As with BMD, alendronate impairs the action of teriparatide to increase bone turnover in men.     

KL-6 is a long-term disease-activity biomarker for interstitial lung disease associated with polymyositis/dermatomyositis,but is not a short-term disease-activity biomarker

Abstract

Objectives: We aimed to evaluate the usefulness of serum KL-6 for interstitial lung disease (ILD) with polymyositis/dermatomyositis (PM/DM).

Methods: All consecutive and previously untreated adult patients with PM/DM who were admitted to our hospital from 2010 to 2015 were included. The associations between serum KL-6 levels and clinical information were retrospectively analyzed.

Results: Baseline serum KL-6 levels were significantly higher in patients with ILD than in those without (n?=?41 and 15, respectively; p?<?.001). In the 14 patients whose ILD improved within 4 weeks post-treatment, their serum KL-6 levels did not significantly decrease at 2 weeks, 4 weeks, or 3 months post-treatment (p?=?1.00, 1.00, and .83, respectively). Conversely, their serum KL-6 levels significantly decreased at 6, 9, and 12 months post-treatment (p?=?.01 in all comparisons). In the 12 patients whose ILD remained unchanged or deteriorated in 4 weeks post-treatment, only the difference between their serum KL-6 levels at 3 and 12 months was significant (p?=?.003).

Conclusions: The present study validated the serum KL-6 as a diagnostic marker for ILD in PM/DM. However, serum KL-6 is not a short-term disease-activity biomarker for ILD with PM/DM, but it is a long-term disease-activity biomarker.     

Effect of mucosal healing (Mayo 0) on clinical relapse in patients with ulcerative colitis in clinical remission

Objective: The aim of this study was to identify the effect of mucosal healing (MH) on clinical relapse in patients with ulcerative colitis (UC) who are in clinical remission, with special reference to Mayo endoscopic subscore 0.

Methods: Between November 2005 and December 2013, medical records from a total of 215 patients with UC who underwent colonoscopic examination at the time of clinical remission were retrospectively reviewed. Endoscopic MH was defined as a ‘0 point’ of Mayo endoscopic subscore (Mayo 0). Patients were categorized into two groups according to Mayo endoscopic subscore and then analyzed.

Results: The baseline characteristics of both groups (MH vs. no-MH), including age at diagnosis, gender, and initial clinical and colonoscopic findings, were not significantly different. The median follow-up duration was 80 (12–118) months. Factors predictive of longer clinical remission duration were age ≥30 years at diagnosis (≥30 years vs. <30 years; hazard ratio [HR] 3.16, 95% CI 1.88–5.30, p?p?=?0.015), and presence of MH at clinical remission (HR 1.95, 95% CI 1.15–3.32, p?=?0.014). With a Cox regression model, patients with MH at clinical remission were more likely to have longer duration of clinical remission than patients without MH.

Conclusion: The achievement of MH, Mayo 0 in particular, in patients with UC who are in clinical remission is important in predicting a favorable disease course prognosis.     

The effectiveness of interactive multi-modality intervention on self-management support of type 2 diabetic patients in Thailand: a cluster-randomized controlled trial

This cluster-randomized controlled trial study aimed to assess the effectiveness of the interactive multi-modality technology (IMM) as an intervention to increase self-management among type 2 diabetic patients in a 3-month period. The IMM intervention contained email, Short Message Service (SMS), and website with four main functions (i.e., self-regulation, self-monitoring and assessment, social support, and reminder system—linked to email and SMS). In this trial, four public offices in the Bangkok Metropolis were recruited and randomly assigned into either the intervention or the control group. One hundred and twenty-six Thai patients who had met inclusion criteria (hemoglobin A1c or A1c >7.0 %, no serious illness, and Internet and mobile phone accessibility) were subsequently assigned to the intervention (n = 78) and the control (n = 48) groups. Patients in the intervention group received the IMM intervention. Those in the control group received self-management knowledge via email only. Outcome measures, A1c, and behavioral questionnaires (Diabetes Quality of Life, Self-efficacy, and Self-care Management) were applied to all patients at baseline and at 3-month follow-up. T test and chi-square test were used to analyze the data. After 3 months, 55 (out of 78) and 30 (out of 48) patients remained in the study. Main findings revealed a significant difference in A1c level between the groups (p < 0.001). The self-care management score increased in both groups, but the increase was significantly higher in the intervention group (p < 0.001). For the first time, this demonstrates the effectiveness of the IMM intervention among type 2 diabetic Thai patients with computer literacy.

     

Disease-modifying anti-rheumatic drug effect of denosumab on radiographic progression in rheumatoid arthritis: a systematic review of the literature

The aim of this study was to evaluate the structural effect of denosumab on patients with rheumatoid arthritis (RA). We performed a systematic review of the literature in the following databases: PubMed, Cochrane, Web of Science, ClinicalTrials.gov, and the WHO International Clinical Trials Registry Platform. All studies evaluating the structural effect of denosumab on RA and meeting predefined criteria were included. Data regarding disease activity, progression of joint damage, joint space narrowing, and safety were recorded. Among 168 studies identified, only 4 were finally included in this review, involving a total of 687 patients. These 4 studies showed that denosumab is effective on joint damage at 6 and 12 months as compared to placebo, alendronate, and biological disease-modifying anti-rheumatic drugs (bDMARDs) alone. No effect was observed in terms of joint space narrowing, and DAS28 and HAQ scores remained unchanged. No case of osteonecrosis of the jaw or atypical fracture was recorded, and safety was similar in both denosumab and control groups. Denosumab appears to be effective on joint erosion at 6 and 12 months in patients with RA meeting the ACR criteria, treated or not by a biologic, with excellent safety.     

Efficacy of Denosumab for Osteoporosis in Patients with Rheumatic Diseases

Objective Denosumab, an anti-RANKL monoclonal antibody, was reported to improve bone mineral density (BMD) and reduce fracture risk, offering favorable efficacy against postmenopausal osteoporosis. However, some patients have experienced a reduced BMD despite denosumab therapy. Methods We performed an observational study to clarify the clinical efficacy of denosumab for osteoporosis in rheumatic disease patients. Serum levels of bone turnover markers and lumber BMD in 100 rheumatic disease patients were examined at baseline and 6 and 12 months after denosumab therapy. The independent influence of changes in the BMD was examined by multiple regression analyses adjusted for patient characteristics and bone turnover markers. Results As bone resorption markers, serum levels of N-telopeptide crosslinked of type I collagen (NTx) and tartrate-resistant acid phosphatase isoform 5b were statistically decreased after 12 months. As bone formation markers, serum levels of osteocalcin, procollagen type I N-terminal peptide, and bone alkaline phosphatase were significantly decreased after 12 months. The mean BMD was significantly increased after 12 months. However, in 10 patients, the BMD decreased. A multivariate analysis of factors related to BMD changes highlighted a young age, low prednisolone dosage, and reduction in NTx. Conclusions Denosumab increases the BMD to combat osteoporosis in rheumatic disease patients, and potential predictors of a better response to denosumab include a young age, reduction in bone turnover markers, and low-dose glucocorticoid use.     

Effect of zoledronic acid on markers of bone turnover and mineral density in osteoporotic patients with beta-thalassaemia

Osteoporosis has emerged as an important cause of morbidity in patients with thalassemia major. Studies regarding the efficacy of bisphosphonates in thalassemia-induced osteoporosis have yielded conflicting results. We performed this prospective study to evaluate the efficacy of zoledronic acid in osteoporotic patients with thalassemia major. Patients, 29, were given 1 mg zoledronic acid intravenously every 3 months for a total of four doses. Twenty age- and sex-matched healthy blood donors served as controls. Before each infusion and 3 months after the last infusion, we determined serum levels of osteoprotegerin (OPG), N-terminal cross-linking telopeptide of type I collagen (NTX), osteocalcin (OC) and insulin-like growth factor 1 (IGF-1). Bone mineral density (BMD) of the lumbar spine was measured at baseline and after the treatment’s completion. At baseline, OPG did not differ significantly between patients and controls (p=0.2), NTX were higher in patients although not significantly (p=0.139), whereas, OC levels were significantly higher and IGF-1 levels significantly lower in patients than in controls (p<0.001 and p<0.006, respectively). Zoledronic acid administration resulted in a significant decrease in NTX, OC and IGF-1 (p<0.05, p<0.001 and p<0.05, respectively) and in a significant increase in OPG and BMD (p<0.05 for both comparisons). The change in NTX, osteocalcin and IGF-1 became significant as early as 3 months after the first administration of zoledronic acid, while the change in OPG reached significance only after three infusions. Our study supports the effectiveness of bisphosphonates in the treatment of thalassemia-induced osteoporosis.     

Lactose-reduced infant formula with added corn syrup solids is associated with a distinct gut microbiota in Hispanic infants

ABSTRACT

Infant formula feeding, compared with human milk, has been associated with development of a distinct infant gut microbiome, but no previous study has examined effects of formula with added sugars. This work examined differences in gut microbiota among 91 Hispanic infants who consumed human milk [at breast (BB) vs. pumped in bottle (BP)] and 2 kinds of infant formula [(traditional lactose-based (TF) vs. lactose-reduced with added sugar (ASF)]. At 1 and 6 months, infant stool was collected to characterize gut microbiota. At 6 months, mothers completed 24-hour dietary recalls and questionnaires to determine infant consumption of human milk (BB vs. BP) or formula (TF vs. ASF). Linear regression models were used to determine associations of milk consumption type and microbial features at 6 months. Infants in the formula groups exhibited a significantly more ‘mature’ microbiome than infants in the human milk groups with the most pronounced differences observed between the ASF vs. BB groups. In the ASF group, we observed reduced log-normalized abundance of Bifidobacteriaceae (TF-BB Mean Difference = ?0.71, ASF-BB Mean Difference = ?1.10), and increased abundance of Lachnospiraceae (TF-BB Mean Difference = +0.89, ASF-BB Mean Difference = +1.20). We also observed a higher Community Phenotype Index of propionate, most likely produced by Lachnospiraceae, in the ASF group (TF-BB Mean Difference = +0.27, ASF-BB Mean Difference = +0.36). This study provides the first evidence that consumption of infant formula with added sugar may have a stronger association than birth delivery mode, infant caloric intake, and maternal BMI on the infant’s microbiome at 6 months of age.     

The usefulness of a new triple combination treatment utilizing methotrexate,salazosulfapyridine, and bucillamine in rheumatoid arthritis

Objectives. Combination treatment with methotrexate, salazosulfapyridine and bucillamine as an alternative to treatment with TNF-inhibiting biologics in rheumatoid arthritis was investigated.

Methods. Twenty-six facilities allied with the Japan Association of Rheumatologists in Private Practice participated in this study. One hundred and twelve patients enrolled in this study, all of whom were within 3 years of diagnosis with rheumatoid arthritis for whom treatment with one DMARD or a combination of two DMARDs had failed (DAS28 > 3.2). Patients chose their own treatment. The triple DMARDs combination group was comprised of 72 patients; the TNF-inhibiting biologics treatment group was comprised of 40 patients.

Results. DAS28 scores for the triple DMARDs combination group and the TNF-inhibiting biologics treatment groups were 4.84 ± 0.96 and 5.23 ± 1.26, and there was no significant difference between the two groups. From the 6th month, average disease activities of both groups were reduced, and there was no difference between the two groups at 12 months (DAS28, 3.39 ± 1.43 and 3.05 ± 1.43, p = 0.39). Furthermore, there was no significant difference in the degree of bone destruction between the two groups at 12 months.

Conclusions. The triple DMARD combination therapy provided a new treatment option for those patients for whom treatment with biologics is difficult.
