Objective. To analyze the clinical relevance of the levels of TNFαblockers and anti-drug antibodies (anti-drug Ab) in patients with rheumatoid arthritis (RA) and spondyloarthritis (SpA) treated with adalimumab (ADA), etanercept (ETA), or infliximab (INF) for a prolonged period of time.Methods. Clinical characteristics (disease activity, and adverse events), serum TNFαblockers, and anti-drug Ab levels were evaluated in 62 RA and 81 SpA patients treated with TNFαblockers for a median of 28 months.Results. Anti-ADA Ab were detected in 1 (4.0%) and anti-INF Ab in 14 out of 57 (24.6%) RA and SpA patients. Patient with anti-ADA Ab and 57.1% patients with anti-INF Ab were considered nonresponders to treatment. Anti-ETA Ab were not found in any of 61 ETA treated patients. Anti-ADA and anti-INF Ab levels differ between responders and nonresponders(P>0.05). Three (5.3%) patients with high serum anti-INF Ab levels developed infusion related reactions. Patients with anti-INF Ab more often required changing to another biologic drug (OR 11.43 (95% CI 1.08–120.93)) and treatment discontinuation (OR 9.28 (95% CI 1.64–52.52)).Conclusion. Patients not responding to treatment had higher serum anti-ADA and anti-INF Ab concentrations. Anti-INF Ab formation is related to increased risk of infusion related reactions, changing to another biologic drug, and treatment discontinuation.

Abstract Hepatotoxicity is a severe problem generally faced by tuberculosis (TB) patients. It is a well-known adverse reaction due to anti-TB drugs in TB patients undergoing long-term treatment. The studies published previously have explored the connection of N-acetyltransferase 2 (NAT2) gene polymorphisms with isoniazid-induced hepatotoxicity, but the results obtained were inconsistent and inconclusive. A comprehensive trial sequence meta-analysis was conducted employing 12 studies comprising 3613 controls and 933 confirmed TB cases using the databases namely, EMBASE, PubMed (Medline) and Google Scholar till December 2017. A significant association was observed with individuals carrying variant allele at position 481C>T (T vs. C: P = 0.001; OR = 1.278, 95% CI = 1.1100–1.484), at position 590G>A (A vs. G: P = 0.002; OR = 1.421, 95% CI = 1.137–1.776) and at position 857G>A (A vs. G: P = 0.0022; OR = 1.411, 95% CI = 1.052–1.894) to higher risk of hepatotoxicity vis-à-vis wild-type allele. Likewise, the other genetic models of NAT2 gene polymorphisms have also shown increased risk of hepatotoxicity. No evidence of publication bias was observed. These results suggest that genetic variants of NAT2 gene have significant role in isoniazid induced hepatotoxicity. Thus, NAT2 genotyping has the potential to improve the understanding of the drug–enzyme metabolic capacity and help in early predisposition of isoniazid-induced hepatotoxicity.

Objective To evaluate safety and efficacy of long-term denosumab 60 mg every 6 (Q6M) or 3 months (Q3M) in rheumatoid arthritis (RA) patients. Methods This 12-month, randomised, double-blind, placebo-controlled, multicentre phase 3 trial with an open-label extension period from 12 to 36 months (DESIRABLE) enrolled Japanese RA patients treated with placebo for 12 months then denosumab Q6M (P/Q6M) or denosumab Q3M (P/Q3M); denosumab Q6M for 36 months (Q6M/Q6M); or denosumab Q3M for 36 months (Q3M/Q3M). Efficacy was assessed by van der Heijde modified total Sharp (mTSS), bone erosion (ES), and joint space narrowing (JSN) scores. Results Long-term treatment better maintained mTSS and ES suppression in the P/Q3M and Q3M/Q3M versus P/Q6M and Q6M/Q6M groups; changes from baseline in total mTSS at 36 months were 2.8 (standard error 0.4), 1.7 (0.3), 3.0 (0.4), and 2.4 (0.3), respectively; corresponding changes in ES were 1.3 (0.2), 0.4 (0.2), 1.4 (0.2), and 1.1 (0.2). No JSN effect was observed. Bone mineral density consistently increased in all groups after denosumab initiation, regardless of concomitant glucocorticoid administration. Serum C-telopeptide of type I collagen decreased rapidly at 1-month post-denosumab administration (both in the initial 12- month [Q3M, Q6M groups] and long-term treatment [P/Q3M, P/Q6M groups] phases). Adverse event incidence leading to study drug discontinuation was similar across treatment groups. Conclusion Denosumab treatment maintained inhibition of progression of joint destruction up to 36 months. Based on effects on ES progression, higher dosing frequency at an earlier treatment stage may be needed to optimise treatment. Denosumab was generally well tolerated.

Abstract Purpose While glucocorticoids (GCs) are effective in large vessel vasculitis (LVV), they may cause serious adverse events (AEs), especially if taken for longer durations and at higher doses. Unfortunately, patients suffering from LVV often need long-term treatment with GCs; therefore, toxicity needs to be expected and countered. Recent Findings GCs remain the mainstay of therapy for both giant cell arteritis and Takayasu arteritis. In order to minimize their toxicity, the following strategies should be considered: GC tapering, administration of conventional synthetic (e.g., methotrexate) or biologic (e.g., tocilizumab) GC-sparing agents, as well as monitoring, prophylaxis, and treatment of GC-related AEs. Several drugs are currently under investigation to expand the armamentarium for the treatment of LVV. Summary GC treatment in LVV is effective but associated with toxicity. Strategies to minimize this toxicity should be applied when treating patients suffering from LVV.

Tofacitinib is a Jak inhibitor developed as a treatment for rheumatoid arthritis. Tofacitinib is metabolized mainly through hepatic CYP3A1/2, followed by CYP2C11. Rheumatoid arthritis tends to increase renal toxicity due to drugs used for long-term treatment. In this study, pharmacokinetic changes of tofacitinib were evaluated in rats with gentamicin (G-ARF) and cisplatin-induced acute renal failure (C-ARF). The time-averaged total body clearance (CL) of tofacitinib in G-ARF and C-ARF rats after 1-min intravenous infusion of 10 mg/kg was significantly decreased by 37.7 and 62.3%, respectively, compared to in control rats. This seems to be because the time-averaged renal clearance (CLR) was significantly lower by 69.5 and 98.6%, respectively, due to decreased creatinine clearance (CLCR). In addition, the time-averaged nonrenal clearance (CLNR) was also significantly lower by 33.2 and 57.4%, respectively, due to reduction in the hepatic CYP3A1/2 and CYP2C11 subfamily in G-ARF and C-ARF rats. After oral administration of tofacitinib (20 mg/kg) to G-ARF and C-ARF rats, both CLR and CLNR were also significantly decreased. In conclusion, an increase in area under plasma concentration-time curves from time zero to time infinity (AUC) of tofacitinib in G-ARF and C-ARF rats was due to the significantly slower elimination of tofacitinib contributed by slower hepatic metabolism and urinary excretion of the drug.

ABSTRACT Objective: The aim of this study is to determine the demographic and clinical characteristics associated with the need for long-term treatment in a child psychiatry facility. Method: Demographic characteristics, diagnosis, source of referral, time elapsed between the earthquake and the request for care, and the treatment prescribed in the baseline assessment were compared between a group of subjects that required long-term treatment (LTT) and a group that was discharged after a brief intervention (D). Results: A total of 171 patients were seen, and 27% of the subjects required LTT. In general, these subjects were younger, referred from highly affected areas, presented a delay in seeking care, and were mainly diagnosed with anxiety and stress-related disorders. Conclusions: These findings suggest the need for research regarding the design of mental health programs for the early detection of psychopathology after natural disasters in children and adolescents.
