Minocycline for Depressive Symptoms: a Meta-Analysis of Randomized, Double-Blinded, Placebo-Controlled Trials

Neuroinflammation appears to be associated with the neurobiology of depression, and treatments targeting inflammation have shown promising results in depression. This meta-analysis examined the efficacy and safety of minocycline, an anti-inflammatory drug, for the treatment of depressive symptoms. A systematic electronic literature search was independently conducted by two investigators. Standardized mean differences (SMDs) and risk ratio (RR) with their 95% confidence interval (CI) were calculated using a random-effect model. Four RCTs (n = 211) were identified for meta-analysis. Minocycline showed a significant trend of improvement in depressive symptoms compared to placebo [4 RCTs, n = 190, SMD: -0.54 (95%CI:-1.12, 0.04), P = 0.07; I² = 73%]. Subgroup analyses showed that minocycline was superior to placebo in improving depressive symptoms in studies of unipolar depression (3 RCTs, n = 151, SMD: -0.77 (95%CI:-1.32, -0.22), P = 0.006; I² = 60%) and in studies using minocycline monotherapy [SMD: -1.06 (95%CI:-1.68, -0.44), P = 0.0008]. The rates of discontinuation due to any reasons [RR: 1.48 (95%CI: 0.79, 2.77), P = 0.22, I² = 0%] and adverse drug reactions [RR: 0.32 to 1.98 (95%CI: 0.03, 14.74), P = 0.19 to 0.84, I² = 0% to 31%] were similar between minocycline and placebo. Minocycline appears to be effective and well-tolerated in ameliorating depressive symptoms in unipolar depression. Future large RCTs with sufficient duration is needed to confirm the positive effects of minocycline in treating depressive symptoms.

Diabetes Remission Rate after Sleeve Gastrectomy or Roux-en-Y Gastric Bypass; Utilizing Individualized Metabolic Surgery Score for Korean Patients

Purpose

The purpose of this study is to evaluate the usefulness of individualized metabolic surgery score for Korean patients in determining bariatric surgical procedures.

Materials and Methods

A total of 135 patients with type 2 diabetes mellitus who underwent sleeve gastrectomy (n=19) or Roux-en-Y gastric bypass (n=116) at our institute with a 1-year follow up were analyzed for the predictive power of diabetes remission using the individualized metabolic surgery scoring system.

Results

At the postoperative follow-up of 1 year, the remission of type 2 diabetes mellitus (HbA_1C<6.5%, off medications) was achieved in 88 (65.2%) patients. The remission rates showed no significant differences between patients who underwent sleeve gastrectomy and Roux-en-Y gastric bypass (63.2% versus 65.5%; P=0.84), regardless of the severity of type 2 diabetes mellitus. Although there was no statistically significant difference in the remission rate according to the bariatric surgery procedures (P>0.99 in mild, P=0.11 in moderate, P>0.99 in severe IMS score), remission rates were higher in moderate severity patients who underwent Roux-en-Y gastric bypass than in those who underwent sleeve gastrectomy (69.7% versus 37.5%).

Conclusion

The remission rates after bariatric surgery procedures were similar to that of the previously reported study. Despite the limitations of our data, the individualized metabolic surgery score can be used as a complement to other scoring systems in Korean patients.

Capturing the enthesitis related arthritis contemporary profile of Caucasian patients in the era of biologics

To describe the profile of Enthesitis Related Arthritis' (ERA) patients, in the era of biologic DMARDs (bDMARDs). This retrospective cohort study included patients with ERA monitored on a 3-month schedule for at least 1 year. Their metric assessment included the disease status and damage by applying the contemporary tools clinical-Juvenile Arthritis Disease Activity Score (c-JADAS), Juvenile Spondyloarthritis Disease Activity Index (JSpADA), clinical remission (CR) on/off medication and Juvenile Arthritis Damage Index (JADI). 43 patients (males 26) were enrolled, with a mean disease onset of 10.75 years. Median lag time from diagnosis to bDMARDs was 8.5 months. Patients with sacroiliitis received earlier bDMARDs (hazard ratio, HR 3.26). 36/43 patients achieved CR on medication (median time 11 months), which was correlated with compliance (HR: 3.62). The percentage of CR in patients with or without sacroiliitis was 35% and 63% respectively (p = 0.02). Twenty patients (47%) experienced a flare following CR (75%). The median flare-free survival following CR on/off medication was 42 and 34 months, respectively. At the last evaluation, both median baseline cJADAS and JSpADA dropped to 0, 13/43 patients had a persistent disease activity, while 17/43 and 13/43 patients were in CR on/off medication, respectively. The median patient percentage of CR was 54% and no patient had a JADI > 0. Increased lag time to bDMARDs was associated with increased CR (Odds ratio: 1.48). Early administration of bDMARDs and compliance improved long-term outcome of ERA. Sacroiliitis was a negative prognostic factor with an increased need for bDMARDs and diminished rates of CR.

Low-dose ofatumumab for multidrug-resistant nephrotic syndrome in children: a randomized placebo-controlled trial

BACKGROUND

Children with multidrug-resistant nephrotic syndrome (MRNS) are exposed to drug toxicity (steroids/calcineurin inhibitors (CNI)/mycophenolate mofetil (MMF)) and have an increased risk of kidney disease progression. In small case series, the fully humanized anti-CD20 antibody ofatumumab (OFA) induced remission in children with MRNS when at high dose (10,300 mg/1.73 m²) and partial remission at standard dose (1000 mg/1.73 m²).

METHODS

This double-blind randomized placebo-controlled trial tested the efficacy of single infusion OFA in children with proven MRNS and initial chronic renal failure (eGFR [median/range] 119/38-155 ml/min/1.73 m² in Placebo arm vs. 65/19-103 ml/min/1.73 m² Intervention). Children who had been resistant to a combination of CNI and steroids, with or without MMF or rituximab, were randomized to receive single infusion OFA (1500 mg/1.73 m²) (Intervention arm) or normal saline (Placebo arm). We assessed complete or partial remission of proteinuria after 3 months (primary outcome), and after 6 and 12 months (secondary outcomes), as well as progression to end-stage kidney disease.

RESULTS

After 13 of the planned 50 children (25%) were randomized, the data safety and monitoring board recommended study termination for futility. All 13 children remained nephrotic. Renal function worsened in 5 children (2 in Intervention arm, 3 in Placebo arm) who required renal replacement therapy during the study period. Circulating CD20 was reduced following OFA infusion and remained low for > 3 months.

CONCLUSIONS

OFA given in one single infusion of 1500 mg/1.73 m² doses does not induce remission in MRNS. Regimens based on higher OFA doses should be tested in clinical trials.

Comparison of remission and low disease activity states with DAPSA, MDA and VLDA in a clinical trial setting in psoriatic arthritis patients: 2-year results from the FUTURE 2 study

OBJECTIVES

Remission (REM) or low disease activity (LDA) states were compared in a clinical trial setting of the FUTURE 2 study (NCT01752634) using Disease Activity Index for Psoriatic Arthritis (DAPSA) and Minimal Disease Activity (MDA) composite indices in secukinumab treated PsA patients.

METHODS

The proportion of patients reaching DAPSA-REM (cut-off ≤4) or REM+LDA (≤14), and very low disease activity (VLDA; achieving 7/7 criteria) or MDA (≥5/7), were compared in the overall population, by prior use of anti-TNF therapy, and by time since diagnosis using as observed data. The proportion of patients who met individual core component and other variables of interest were also computed to assess residual disease activity in DAPSA-REM/REM+LDA states and VLDA/MDA responses. The relationship between DAPSA/MDA and patient reported outcomes (PROs), including health-related quality of life, physical function, and fatigue were assessed using mixed model for repeated measures.

RESULTS

More patients could achieve DAPSA-REM or DAPSA-REM+LDA status than VLDA or MDA responses, respectively, at all the time points in the overall population, irrespective of anti‒TNF status and time since diagnosis. Higher proportion of patients reaching DAPSA-REM or VLDA achieved more thresholds of core components (joints, pain, patient and physician global assessments, and function) than DAPSA-REM+LDA or MDA over Week 104. There were differences with numerically higher proportion of patients achieving patient global assessment ≤10 mm and ≤20 mm, and physician global assessment ≤10 mm with MDA than with DAPSA-REM+LDA, and patient pain VAS ≤15 mm, PASI ≤1, HAQ ≤0.5 with VLDA or MDA than with DAPSA-REM or DAPSA-REM+LDA, respectively, through 104 weeks. Improvements in PROs were significantly better for patients in DAPSA-REM+LDA versus DAPSA-moderate+high disease activity status, and for MDA responders versus non-responders.

CONCLUSION

These analysis add to the evidence that both DAPSA and MDA composite index measures can be used for evaluation of the status and treatment response utilizing a treat to target approach in PsA patients in a clinical trial setting and improve patient health related outcomes.

Shorter Relapse-Free Period after Leukocyte Removal Therapy in Younger than Older Patients with Ulcerative Colitis

BACKGROUND

Leukocyte removal therapy (LRT) is an effective treatment for active ulcerative colitis (UC). The present study was performed to evaluate the relapse-free period after LRT and identify risk factors for relapse.

METHODS

In total, 94 patients who underwent first-time LRT for remission of moderate to severe UC from April 2004 to March 2016 were enrolled in the present study. The patients were randomly assigned to one of 2 treatments: leukocytapheresis (LCAP; n = 43) or granulocyte and monocyte/macrophage adsorptive apheresis (GMA; n = 51). The 5-year cumulative relapse-free rate and risk factors for relapse were evaluated.

RESULTS

The therapeutic response rate was 82% for GMA and 70% for LCAP without a statistically significant difference. The 5-year relapse-free rate was 34.7% in the LRT group. The 5-year relapse-free rate in patients aged > 40 years was 49.9%, which was significantly higher than that in patients aged ≤40 years (22.9%, p < 0.01). The relapse-free period was longer in the older than younger patients.

CONCLUSIONS

The relapse-free period after LRT was examined in patients with UC, and 34.7% of patients achieved clinical remission within a 5-year period. The risk factor for early relapse after LRT was younger age.

Osteoporosis in patients with rheumatoid arthritis: trends in the German National Database 2007-2017

Osteoporosis is a frequent comorbidity in rheumatoid arthritis (RA). Due to the improved treatment options for RA, we expect a long-term decrease in osteoporosis as an accompanying disease. Data from the German National Database (NDB) were used to investigate whether the frequency of osteoporosis has changed in the last 10 years. From 2007 to 2017, approximately 4000 patients were documented annually with data on therapy and comorbidity. The cross-sectional data were summarised descriptively. Age, sex, disease duration, disease activity and glucocorticoids were considered as influencing factors. The Cochrane-Armitage test for trend was used to test whether the frequency of osteoporosis at the first visit changed from 2007 to 2017. Osteoporosis frequency in RA patients (mean age 63 years, 75% female) decreased from 20% in 2007 to 6% in 2017 (p < 0.001). The decrease affected women (22% to 17%) and men (14% to 8%) in all age groups and both short-term (≤ 2-year disease duration: 9% to 3%) and long-term RA patients (> 10-year disease duration: 28% to 20%). Patients with high disease activity and patients who took glucocorticoids (GC) were more often affected by osteoporosis than patients in remission or without GC. Drug prophylaxis in patients without osteoporosis increased (20% to 41% without GC, 48% to 55% with GC). Men with GC received less prophylactic treatment than women (48% vs. 57% in 2017). In this cohort, osteoporosis in patients with RA is less frequently observed compared to former years. RA-specific risk factors for osteoporosis such as disease activity and GC therapy have declined but long-term GC use is still present. Assessment of osteoporosis in RA patients should be investigated more consistently by bone density measurement. Male RA patients still need to be given greater consideration regarding osteoporosis drug prophylaxis, especially when GC therapy is needed.

Determinants of outcome of transsphenoidal surgery for Cushing disease in a single-centre series

BACKGROUND

First-line therapy of Cushing disease (CD) is transsphenoidal surgery (TSS) aimed to obtain a complete removal of the pituitary adenoma and remission of disease.

PURPOSE

To analyse the surgical outcome of patients with CD who underwent TSS in our Centre.

METHODS

Retrospective analysis on patients with CD who underwent TSS between 1990 and 2016.

RESULTS

We analysed 102 TSS that included: 84 first TSS and 18 second and third TSS. The overall remission rate after surgery was 76.5%, with a significant higher percentage of remitted patients after the first TSS compared to the subsequent TSS (82% vs 50%, p = 0.014). The remission after the first TSS was significantly higher when performed by a dedicated surgical team (DST) (89.8% vs 71% p = 0.04) and when the immunohistochemical examination confirmed the adrenocorticotropic adenoma (87% vs 55%, p = 0.04). Neuroradiological findings influenced the surgical outcome in a non-significant manner. Post-TSS complications were reported in 32 patients, with no significant variation when TSS was performed by DST. In case of reintervention, remission of disease was obtained in 72.7% of microadenoma, while no remitted patients were observed in case of macroadenomas. The DST did not significantly improve the outcome.

CONCLUSION

Cushing disease is characterized by a broad spectrum of neuroradiological presentation. Despite the availability of a DST make the TSS a safe and effective first-line treatment among all these patients, a precise pre-treatment evaluation is needed in order to define the aim of neurosurgery and to schedule the management of recurrent disease.

Remission and recurrence in bipolar disorder: The data from health outcomes and patient evaluations in bipolar disorder (HOPE-BD) study

BACKGROUND

The HOPE-BD was a naturalistic study established to follow individuals in Canada seeking treatment for bipolar disorder (BD). The study aimed to examine the course of BD and describe how clinical and sociodemographic factors are associated with outcomes.

METHODS

Individuals with BD had their clinical data recorded at enrolment and were naturalistically treated. Participant were followed for up to four years, and visits occurred at least once every three months. We investigated the longitudinal outcomes with logistic, Cox, and quantile regressions.

RESULTS

Among the 354 participants, 57.3% had BD type I. Depression as first episode, younger ages at onset and older ages of the first professional help predicted longer delays in correct diagnosis. Among the symptomatic patients at baseline, the median time to remission was 10.9 months. Comorbid alcohol use disorder and the severity of baseline depressive symptoms predicted longer times to remission. Among the euthymic participants, the median time to recurrence was 14.5 months. History of anxiety disorder and younger ages at onset predicted shorter times to recurrence. Baseline depression scores predicted recurrence in euthymic patients.

LIMITATIONS

We did not investigate the predictors of each polarity. Our findings may not apply to individuals followed in non-specialised outpatient services.

CONCLUSION

Our study reinforces the necessity of early diagnosis and interventions, as well as the importance of treating depressive symptoms and comorbidities.

Subclinical Treatment Targets in Rheumatology: Lessons from Randomized Clinical Trials in Rheumatoid Arthritis

In treat-to-target strategies, choosing the correct target is fundamental to success. The target should be associated with future good outcomes for the patient. Most rheumatic diseases are characterized by inflammation, affecting different tissues depending on the condition. Low-grade, subclinical inflammation is by definition not apparent on clinical examination, but may have significant long-term consequences for the individual. It has thus been debated whether targeting subclinical inflammation would improve long-term outcomes in rheumatoid arthritis. The authors use rheumatoid arthritis as an example to describe and discuss the status of subclinical targets in treat-to-target strategies within rheumatology.

Tapering of biological antirheumatic drugs in rheumatoid arthritis patients is achievable and cost-effective in daily clinical practice: data from the Brussels UCLouvain RA Cohort

Background/purpose

Studies have demonstrated that rheumatoid arthritis (RA) patients who achieve low disease activity or remission are able to taper biological disease-modifying antirheumatic drugs (bDMARDs). The aim of this study was to evaluate the proportion of patients in whom bDMARDs can be tapered in daily practice and to analyse the characteristics of these patients. Other objectives were to analyse which bDMARDs are more suitable for dose reduction and the cost savings.

Results

Data from 332 eligible RA patients from our Brussels UCLouvain cohort were retrospectively analysed; 140 patients (42.1%) received a tapered regimen, and 192 received stable doses of bDMARDs. The age at diagnosis (43.1 vs 38.7 years, p = 0.04), health assessment questionnaire (HAQ) score (1.3 vs 1.5, p = 0.048), RF positivity rate (83.3 vs 72.9%, p = 0.04) and disease duration at the time of bDMARD introduction (9.7 vs 12.1 years, p = 0.034) were significantly different between the reduced-dose and stable-dose groups. Interestingly, relatively more patients receiving a tapered dose were treated with a combination of bDMARDs and methotrexate (MTX) (86.7% vs 73.8%, p = 0.005). In our cohort, anti-TNF agents were the most commonly prescribed medications (68%). Only 15 patients experienced a flare during follow-up. Adalimumab, etanercept and rituximab were the most common bDMARDs in the reduced-dose group and were associated with the most important reductions in annual cost.

Conclusion

In daily practice, tapering bDMARDs in RA patients who have achieved low disease activity or remission is an achievable goal in a large proportion of patients, thereby reducing potential side effects and annual drug-associated costs. The combination of bDMARDs with MTX could improve the success of dose reduction attempts.

Trial registration

This retrospective non-interventional study was retrospectively registered with local ethics approval.

Ustekinumab for the treatment of refractory pediatric Crohn's disease: a single-center experience

BACKGROUND/AIMS

Despite the well-established efficacy of tumor necrosis factor (TNF) antagonists as treatment options for Crohn's disease, many pediatric patients need a change in therapy due to adverse events and loss of response, highlighting the necessity for medications with a different mechanism of action. Ustekinumab has been shown to be effective in inducing clinical remission in some adults with disease refractory to anti-TNF agents, however, minimal data exists in the pediatric population.

METHODS

We conducted a retrospective chart review of 11 pediatric patients receiving ustekinumab, specifically extracting baseline data, information on prior treatment and response, indications for starting ustekinumab, clinical information, and laboratory parameters pre- and post-therapy. Clinical response was defined as a decrease in abbreviated Pediatric Crohn's Disease Activity Index score.

RESULTS

Patients ranged from 12 to 17 years of age upon initiation of treatment with ustekinumab. Five of 11 patients demonstrated a clinical response. Among these patients, 2 remained in clinical remission, while the remaining 3 experienced a secondary loss of response. The other 6 patients were primary nonresponders who either remained unwell or demonstrated slight clinical worsening. All patients who clinically responded to ustekinumab and had an initially elevated CRP experienced complete normalization of their values. Mucosal healing was seen on endoscopy in 1 responder, with 2 other patients showing endoscopic improvement.

CONCLUSIONS

These results demonstrate for the first time that ustekinumab has the potential to induce not only clinical and biochemical remission, but also endoscopic improvement, in the pediatric population. Future research is needed to determine factors that influence response to therapy.

Course of cervical intraepithelial neoplasia diagnosed during pregnancy

PURPOSE

Management of high-grade cervical intraepithelial neoplasia [CIN grade 2 or 3 (CIN2-3)] diagnosed during pregnancy is controversial. Monitoring with colposcopy and cytology every 8-12 weeks is advised by the most current guidelines.

STUDY DESIGN

This study analyzes the course of disease in pregnant women with abnormal cytologies or clinically suspicious cervixes.

RESULTS

In total, 139 pregnant women, at a median age of 31 years (range 19-49), treated at the Colposcopy Unit of the University Medical Center Hamburg-Eppendorf between 2011 and 2017 were identified. During pregnancy, at least one biopsy was performed on 70.5% of patients. In 84.7% of cases, CIN2-3 (CIN2 n = 14 (14.3%), CIN3 n = 69 (70.4%)) was detected, 7.1% (n = 7) of women were diagnosed with CIN1, while no dysplasia was found in 8.2% (n = 8) of cases. No interventions were necessary during pregnancy. Despite explicit invitation, only 72.3% of women with CIN2-3 attended postpartal consultations. While 61.7% showed persistent lesions, 5% were diagnosed with CIN1 and 33.3% with complete remission. During pregnancy, 68.7% of women with prepartal CIN2-3 were tested for HPV infection. Later, 49.1% were followed up postpartally by means of HPV testing and histology. HPV clearance was observed in 36.4% of women with complete histological remission. Postpartum conization was performed on 44.6% of patients with prepartal CIN2-3 diagnosis. CIN2-3 was histologically confirmed in 97.3% cases. Progression from persistent CIN3 to microinvasive carcinoma was observed in a single case.

CONCLUSIONS

High-grade CIN lesions, diagnosed during pregnancy, show a high rate of regression postpartum; whereas, progression to carcinoma is rare. Close and continuous monitoring rarely has any therapeutic consequences. Compliance for postpartal follow-up needs to be improved.

Disease features associated with a low disease impact in patients with psoriatic arthritis: results of a cross-sectional multicenter study

BACKGROUND

Patient-reported outcomes measures, such as those provided by the Psoriatic Arthritis Impact of Disease (PsAID) questionnaire, have been found to be a reliable indicator of change during treatment, predictive of long-term outcomes, and the impact of psoriatic arthritis (PsA) on patients' lives. The objective of the study was to describe the demographic and clinical characteristics of PsA patients with a low disease impact and to analyze predictive factors for that state.

METHODS

Post hoc analysis of a cross-sectional multicenter study that included 223 consecutive patients. PsAID questionnaire was used to estimate disease impact. Patients with a PsAID < 4 were considered in low disease impact. Minimal disease activity (MDA) response and the Health Assessment Questionnaire (HAQ) were also assessed. The degree of agreement between the different outcomes was addressed by Cohen's kappa index.

RESULTS

One hundred and twenty-two (54.7%) patients reached a PsAID < 4. Among them, 52.0% and 68.0% presented articular or skin remission, respectively. Almost 75% of patients were in MDA state and 85.2% presented a low disability state according to the HAQ. A moderate concordance between HAQ ≤ 0.5 and PsAID < 4 (k = 0.53), fair between MDA and PsAID < 4 (k = 0.36), and moderate between DAPSA remission and PsAID < 4 (k = 0.46) was observed. Multivariate logistic regression analysis showed that patients with distal interphalangeal joint (DIP) disease (OR 0.40, 95%CI, 0.20-0.79, p = 0.009), family history of PsA (OR 0.25, 95%CI, 0.09-0.72, p = 0.010), and higher C-reactive protein (OR 0.92, 95%CI, 0.85-0.99, p = 0.036) were significantly less likely to reach a PsAID < 4.

CONCLUSIONS

There is certain discrepancy between disease activity measures and a low impact of disease in PsA. Clinical features (DIP joint involvement), biologic activity, and genetic factors (familial history) seem to be associated with lower odds of reaching a low disease impact.

Prognostic factors for remission, relapse, and treatment complications in type 1 autoimmune hepatitis

Background and aim

Autoimmune hepatitis (AIH) is a rare chronic form of hepatitis, the prognosis for which has not been definitively established. The current study aimed to define the prognostic factors for remission and compare the median time to remission, complications, and relapse rate between type 1 AIH patients treated with prednisolone monotherapy and those treated using prednisolone in combination with azathioprine.

Materials and methods

The data of 86 patients diagnosed with type 1 AIH between January 1998 and January 2018 were retrospectively reviewed. Clinical, serological, and histological parameters were obtained. Cox-proportional hazard and logistic regression analyses were applied to the data.

Results

The prognostic factors related to complete remission were absence of liver cirrhosis, hypertension, and azathioprine exposure. The median time to complete remission of the prednisolone group (92 days; 95%CI; 65–264 days) was significantly shorter (P = 0.01) than that of the combination group (336 days; 95%CI; 161–562 days); however, the prednisolone group had higher rates of treatment complications—including skin and soft tissue infections (P = 0.010) and cushingoid appearance (P = 0.011)—than the combination group. The prednisolone group also had a higher relapse rate (odds ratio 6.13, 95% CI 1.72–21.80, P = 0.005).

Conclusions

The absence of liver cirrhosis and hypertension at the time of diagnosis and no azathioprine exposure during the treatment period were favorable prognostic factors for complete remission. The prednisolone group had a significantly shorter median time to complete remission but higher rates of treatment complications and a higher relapse rate than the combination group.

Associated factors of poor treatment outcomes in patients with giant cell arteritis: clinical implication of large vessel lesions

Background

Relapses frequently occur in giant cell arteritis (GCA), and long-term glucocorticoid therapy is required. The identification of associated factors with poor treatment outcomes is important to decide the treatment algorithm of GCA.

Methods

We enrolled 139 newly diagnosed GCA patients treated with glucocorticoids between 2007 and 2014 in a retrospective, multi-center registry. Patients were diagnosed with temporal artery biopsy, 1990 American College of Rheumatology classification criteria, or large vessel lesions (LVLs) detected by imaging based on the modified classification criteria. Poor treatment outcomes (non-achievement of clinical remission by week 24 or relapse during 52 weeks) were evaluated. Clinical remission was defined as the absence of clinical signs and symptoms in cranial and large vessel areas, polymyalgia rheumatica (PMR), and elevation of C-reactive protein (CRP) levels. A patient was determined to have a relapse if he/she had either one of the signs and symptoms that newly appeared or worsened after achieving clinical remission. Re-elevation of CRP without clinical manifestations was considered as a relapse if other causes such as infection were excluded and the treatment was intensified. Associated factors with poor treatment outcomes were analyzed by using the Cox proportional hazard model.

Results

Cranial lesions, PMR, and LVLs were detected in 77.7%, 41.7%, and 52.5% of the enrolled patients, respectively. Treatment outcomes were evaluated in 119 newly diagnosed patients who were observed for 24 weeks or longer. The mean initial dose of prednisolone was 0.76 mg/kg/day, and 29.4% received any concomitant immunosuppressive drugs at baseline. Overall, 41 (34.5%) of the 119 patients had poor treatment outcomes; 13 did not achieve clinical remission by week 24, and 28 had a relapse after achieving clinical remission. Cumulative rates of the events of poor treatment outcomes in patients with and without LVLs were 47.5% and 17.7%, respectively. A multivariable model showed the presence of LVLs at baseline was significantly associated with poor treatment outcomes (adjusted hazard ratio [HR] 3.54, 95% CI 1.52–8.24, p = 0.003). Cranial lesions and PMR did not increase the risk of poor treatment outcomes.

Conclusion

The initial treatment intensity in the treatment algorithm of GCA could be determined based upon the presence or absence of LVLs detected by imaging at baseline.

Neurological soft signs and neurocognitive deficits in remitted patients with schizophrenia, their first-degree unaffected relatives, and healthy controls

Neurological soft signs (NSS) and neurocognitive deficits (ND) are highly prevalent in schizophrenia, and have been separately proposed as candidate endophenotypes of schizophrenia. However, few relevant studies focus on remitted patients with schizophrenia (RP) and integrate NSS and ND as a composite endophenotype. This study aimed to explore the NSS and ND and examine the comparative relationship between them in RP, their first-degree unaffected relatives (FDR), and healthy controls, furthermore, to seek potential endophenotypes subitems of NSS and ND and create a composite endophenotype. 86 RP, 86 FDR, and 86 healthy controls were included. NSS and ND were independently assessed with Cambridge Neurological Inventory and MATRICS^TM Consensus Cognitive Battery. RP had more NSS and ND than FDR in all subitems except disinhibition, information processing speed, working memory, and visual memory. Similarly, FDR presented poorer performance than controls in all subscales except disinhibition, sensory integration, working memory, and visual memory. Six subitems of NSS and ND met the criteria of endophenotype and the three groups were most accurately classified (71.2%) with these subitems working as a composite endophenotype. Moreover, information processing speed, attention, and social cognition were associated with sensory integration in RP and FDR. These findings add evidences that certain subitems of NSS and ND might be the endophenotypes of schizophrenia and integrating these endophenotypes may prove useful in identifying schizophrenia and high-risk individuals. Furthermore, sensory integration and specific cognitive domains covary, hence suggesting an overlap of compromised underlying neural systems.

Anatomical substrates of symptom remission and persistence in young adults with childhood attention deficit/hyperactivity disorder

Attention deficit/hyperactivity disorder (ADHD) is a highly prevalent neurodevelopmental disorder that emerges in childhood and persists into adulthood in a sizeable portion of afflicted individuals. The persistence of ADHD symptoms elevates the risk of adverse outcomes that result in substantial individual and societal burden. The objective of this study was to delineate neuroanatomical substrates associated with the diversity of adult outcomes of childhood ADHD, which may have considerable value for development of novel interventions that target mechanisms associated with recovery. Structural MRI and diffusion tensor imaging data from 32 young adults who were diagnosed with ADHD combined-type during childhood and 35 group-matched controls were analyzed. Adults with childhood ADHD were divided into 16 remitters and 16 persisters based on DSM-IV criteria. Compared to the controls, ADHD probands showed significantly reduced gray matter (GM) volume in right putamen and white matter (WM) volume in left parieto-insular fiber tracts. Within the ADHD probands, the remitters, as compared to persisters, showed significantly greater volume of right hippocampo-frontal and right parieto-insular WM fiber tracts, and those connecting caudate with the frontal, parietal, occipital, temporal, and insular cortices. Among ADHD probands, increased fractional anisotropy value of left caudate-parietal tract was significantly correlated with reduced hyperactive/impulsive symptoms. These findings suggest that optimal structural development in the WM tracts that connect caudate with cortical areas, especially in the caudate-parietal path, may play an important role in symptom remission in young adults with childhood ADHD.

Treat-to-target in systemic lupus erythematosus: Where are we?

Systemic lupus erythematosus (SLE) is the most paradigmatic disorder within systemic autoimmune diseases. The concept and principles of treat-to-target (T2T) in SLE were established half a decade ago and, since then, remarkable advances have been made. An international consensus was organized in order to define and unify the term remission, although plurality, with subtle nuances still exists and has not been overcome. Also, lupus low disease activity state (LLDAS) was coined as an alternative and, perhaps, more realistic target. Both of them have proven to be meaningful in terms of improving several outcomes, and have opened the path for future research in clinical trials. This review arises from the need to summarize the current state of some of the recommendations of the T2T task force.

Empirical examination of executive functioning, ADHD associated behaviors, and functional impairments in adults with persistent ADHD, remittent ADHD, and without ADHD

BACKGROUND

Previous studies suggest that childhood attention deficit hyperactivity disorder (ADHD) may continue in adulthood, producing adverse effects. Therefore, identifying factors that help to differentiate characteristics of ADHD persistence and remission has practical implications for evaluation and treatment. The first aim of this study was to analyze differences in executive functions (shift, working memory, inhibition, and plan/organize), symptoms associated with ADHD (inattention, hyperactivity, emotional lability, and self-concept), and functional impairments in adults with persistent ADHD (ADHD-P), with remittent ADHD (ADHD-R), and without ADHD (N-ADHD). The second aim was to study the contribution of functional impairments in these three groups based on executive functions and associated ADHD behaviors.

METHODS

Participants were 115 adults, 61 with a childhood ADHD diagnosis (40 persisters and 21 remitters) and 54 individuals with typical development. Self-reports were collected on executive functions, symptoms associated with ADHD, and functional impairments. Multivariate Analyses of Variance were conducted to test differences between the ADHD-P, ADHD-R, and N-ADHD groups on the evaluated variables. In addition, analyses were performed using two structural equation models with observed variables (path analyses).

RESULTS

The results indicated that significant executive and behavioral impairments and adverse functional outcomes in different life domains are related to the diagnostic persistence of ADHD. Recovery from the disorder is associated with better results, although hyperactivity/restlessness behaviors and plan/organize deficits continue to be present in remitter individuals.

CONCLUSIONS

The ADHD-P and ADHD-R groups showed some differences in their executive, behavioral, and functional impairments. Furthermore, the impairments in each group can be predicted by different executive functions and other symptoms associated with the disorder. These results should be taken into account in order to improve clinical practice.

Multimodal neuroimaging-based prediction of adult outcomes in childhood-onset ADHD using ensemble learning techniques

Attention-deficit/hyperactivity disorder (ADHD) is a highly prevalent and heterogeneous neurodevelopmental disorder, which is diagnosed using subjective symptom reports. Machine learning classifiers have been utilized to assist in the development of neuroimaging-based biomarkers for objective diagnosis of ADHD. However, existing basic model-based studies in ADHD report suboptimal classification performances and inconclusive results, mainly due to the limited flexibility for each type of basic classifier to appropriately handle multi-dimensional source features with varying properties. This study applied ensemble learning techniques (ELTs), a meta-algorithm that combine several basic machine learning models into one predictive model in order to decrease variance, bias, or improve predictions, in multimodal neuroimaging data collected from 72 young adults, including 36 probands (18 remitters and 18 persisters of childhood ADHD) and 36 group-matched controls. All currently available optimization strategies for ELTs (i.e., voting, bagging, boosting and stacking techniques) were tested in a pool of semifinal classification results generated by seven basic classifiers. The high-dimensional neuroimaging features for classification included regional cortical gray matter (GM) thickness and surface area, GM volume of subcortical structures, volume and fractional anisotropy of major white matter fiber tracts, pair-wise regional connectivity and global/nodal topological properties of the functional brain network for cue-evoked attention process. As a result, the bagging-based ELT with the base model of support vector machine achieved the best results, with significant improvement of the area under the receiver of operating characteristic curve (0.89 for ADHD vs. controls and 0.9 for ADHD persisters vs. remitters). Features of nodal efficiency in right inferior frontal gyrus, right middle frontal (MFG)-inferior parietal (IPL) functional connectivity, and right amygdala volume significantly contributed to accurate discrimination between ADHD probands and controls; higher nodal efficiency of right MFG greatly contributed to inattentive and hyperactive/impulsive symptom remission, while higher right MFG-IPL functional connectivity strongly linked to symptom persistence in adults with childhood ADHD. Considering their improved robustness than the commonly implemented basic classifiers, findings suggest that ELTs may have the potential to identify more reliable neurobiological markers for neurodevelopmental disorders.

Cluster of Differentiation 96 in Children with Acute Leukemia: A Single Center Cohort Study

Cluster of differentiation 96 (CD96) is an important leukemic stem cells (LSCs) surface marker. We evaluated CD96 expression in children with acute leukemia (AL) and described its relation with treatment response. We conducted a prospective cohort study in Mansoura University Children's Hospital, Egypt during the period from 2014 to 2016. We studied 96 children with AL and 96 controls at clinical, laboratory and radiological levels. We assessed CD96% in LSCs using flow cytometry. AL group included 59 acute lymphoblastic leukemia (ALL) and 37 acute myeloid leukemia (AML) patients. ALL subgroup involved 44 B-ALL and 15 T-ALL patients while AML subgroup included 17 M2, 12 M4 and 8 M5 patients. CD96% was higher in AL group [57.63 (21.18-89.93)] than control [34.12 (16.15-39.51)] (P < 0.001). CD96% was higher in AML [68.25 (31.1-89.86)] than ALL [54.18 (21.18-89.93] (P < 0.001). CD96% in AML was M4 > M2 > M5 (P = 0.04) while within ALL subgroup, no significant difference was found between B-ALL and T-ALL (P = 0.807). CD96% in patients with non-complete remission was higher than those with complete remission (P = 0.004). CD96 is a reliable diagnostic marker for AL mainly AML and could be used as a prognostic marker for treatment response.

Adjunctive intranasal esketamine for major depressive disorder: A systematic review of randomized double-blind controlled-placebo studies

OBJECTIVES

This is a meta-analysis of randomized double-blind controlled-placebo trials (RCTs) examining the effectiveness, tolerability, and safety of intranasal esketamine in treating major depressive disorder (MDD).

METHODS

Standardized mean difference (SMD), risk ratio (RR) and their 95% confidence intervals (CIs) were calculated using RevMan version 5.3.

RESULTS

Four RCTs with 7 active arms covering 708 patients with MDD on intranasal esketamine (n = 419) and placebo (n = 289) were included. Compared with placebo, adjunctive intranasal esketamine was associated with significantly greater study-defined response (RR=1.39, 95%CI: 1.18 to 1.64, P<0.0001) and remission (RR=1.42, 95%CI: 1.17 to 1.72, P = 0.0004) at endpoint assessment. Intranasal esketamine had greater study-defined response starting at 2 h (RR= 2.77, 95%CI: 1.62 to 4.76, P = 0.0002), peaking at 24 h (RR=5.42, 95%CI: 1.38 to 21.20, P = 0.02), and at least lasting for 28 days (RR=1.36, 95%CI: 1.16 to 1.58, P = 0.0001). Similarly, intranasal esketamine had significantly greater study-defined remission starting at 2 h (RR=7.71, 95%CI: 2.16 to 27.55, P = 0.002), peaking at 24 h (RR=6.87, 95%CI: 1.55 to 30.35, P = 0.01), and lasting for 28 days (RR=1.38, 95%CI: 1.11 to 1.72, P = 0.004). Intranasal esketamine had a significantly higher rate of discontinuation due to intolerability (RR=3.50, 95%CI: 1.38 to 8.86, P = 0.008). Discontinuation due to any reasons and inefficacy were similar between the two groups.

CONCLUSION

Intranasal esketamine appears to have an ultra-rapid antidepressant effect for MDD, at least lasting for 28 days. The long-term therapeutic effect and safety of intranasal esketamine need to be further examined in large-scale RCTs.

Achieving complete mental health despite a history of generalized anxiety disorders: Findings from a large, nationally representative Canadian survey

Ideally, the clinical goal for individuals with a history of anxiety disorder is not only to remit from the disorder, but also to reach optimal well-being. This broader concept of recovery aligns with Keyes' concept of complete mental health (CMH), including presence of happiness or life satisfaction, and social and psychological well-being, and absence of any past year mental illness including anxiety disorders, depressive disorders, substance dependence and suicidal ideation. This study's aim was to identify factors associated with CMH in a population-based sample of Canadians with a previous diagnosis of Generalized Anxiety Disorder (GAD) (n = =2128), of whom 40% are currently in CMH. Data were from the 2012 Canadian Community Health Survey-Mental Health (response rate=68.9%). The World Health Organization version of the Composite International Diagnostic Interview (WHOCIDI) scales were used to define lifetime and past-year GAD. Factors associated with complete mental health include female gender, older age, being married, reporting good to excellent physical health, being free of chronic insomnia, being able to manage household activities without difficulties, using religion or spirituality to cope, having a confidant, and never having had a major depressive disorder nor substance dependence. Results of this study suggest many with a history of anxiety disorders can achieve CMH and point to factors that appear to facilitate this process.

Successful long-term remission through tapering tocilizumab infusions: a single-center prospective study

Background

Strategic drug therapy for rheumatoid arthritis (RA) patients with prolonged remission is not well defined. According to recent guidelines, tapering biological Disease-Modifying Anti-Rheumatic Drugs (bDMARDs) may be considered. We aimed to evaluate the effectiveness of long-term maintenance of tocilizumab (TCZ) treatment after the progressive tapering of infusions.

Methods

We conducted an exploratory, prospective, single-center, open-label study, on RA patients with sustained remission of at least 3 months and treated with TCZ infusions every 4 weeks. The initial re-treatment interval was extended to 6 weeks for the first 3 months. Thereafter, the spacing between infusions was determined by the clinician. Successful long-term maintenance following the tapering of TCZ infusions was defined by patients still treated after two years by TCZ with a minimum dosing interval of 5 weeks.

Results

Thirteen patients were enrolled in the study. Eight out of thirteen were still treated by TCZ after two years. Successful long-term maintenance was possible in six patients, with four patients maintaining a re-treatment interval of 8-weeks or more. We observed 5 patients with TCZ withdrawal: one showing adverse drug reaction (neutropenia) and four with secondary failure. Patients achieving successful long-term maintenance with TCZ were significantly younger than those with secondary failure (p < 0.05). In addition, RA patients with positive rheumatoid factor and anti-citrullinated peptide antibodies, experienced a significantly greater number of flares during our 2-year follow-up (p < 0.01).

Conclusions

A progressive tapering of TCZ infusions may be possible for many patients. However, larger studies, including more patients, are needed to confirm this therapeutic option.
