RESUMEN
OBJECTIVES: Acute respiratory distress syndrome (ARDS) related to SARS-CoV-2 is likely due to a cytokine storm characterised by a major release of pro-inflammatory cytokines, including interleukin-6 (IL-6). Blocking excessive IL-6 production might be the key to the COVID-19-ARDS treatment. Beneficial effects of IL-6 blockade using a humanised anti-IL-6 receptor antibody, tocilizumab (TCZ) were previously reported in patients with COVID-19 related ARDS. The aim of the study was to study the variation over time of several biomarkers, demonstrated to be predictors of poor prognostic, in subjects successfully treated with TCZ for severe COVID-19. METHODS: Retrospective analysis of a case series of patients with COVID-19-ARDS, evidenced by RT-PCR and lung CT-scan. Patients with increasing O2 requirements, within the window of opportunity for TCZ treatment (Day 7 to Day 17 after onset of symptoms) were treated with TCZ (2 infusions of 8 mg/kg). Demographic, biological and clinical data were collected from the patients' files. Serum levels of CRP, ferritin, fibrinogen, lymphocytes, platelets, creatinine, D-dimer and liver enzymes were assayed at the time of the first TCZ administration, then every two days for 8 days. RESULTS: 40 patients were treated with TCZ. Most of them had several comorbidities, and all had multiple biological abnormalities (lymphopenia, increased CRP, ferritin, fibrinogen, D-dimer, liver enzymes). 30 patients (75%) benefited from TCZ and 10 patients died. In the survivors, following TCZ administration CRP decreased dramatically as early as day 4 (-86.7%, p<0.0001) and returned to normal at day 6. Fibrinogen and lymphocyte count returned to normal values at day 6. Ferritin also decreased significantly. No significant change was observed for D-dimer (p=0.68) and other studied biomarkers (haemoglobin, leucocyte count, AST). CONCLUSIONS: In patients with COVID-19 acute respiratory distress syndrome, treatment with TCZ resulted in favourable evolution in 75% of the cases. Biomarkers of inflammation (CRP, ferritin, fibrinogen) decreased dramatically as early as the 4th day after TCZ injection. Lymphopenia, a predictor of poor prognostic, was reversed 6 days after TCZ injection.

UNLABELLED: Tumour necrosis factor (TNF)-blocker tapering has been proposed for patients with rheumatoid arthritis (RA) in remission. OBJECTIVE: The trial aims to compare the effect of progressive spacing of TNF-blocker injections (S-arm) to their maintenance (M-arm) for established patients with RA in remission. METHODS: The study was an 18-month equivalence trial which included patients receiving etanercept or adalimumab at stable dose for ≥1 year, patients in remission on 28-joint Disease Activity Score (DAS28) for ≥6 months and patients with stable joint damage. Patients were randomised into two arms: maintenance or injections spacing by 50% every 3 months up to complete stop. Spacing was reversed to the previous interval in case of relapse, and eventually reattempted after remission was reachieved. The primary outcome was the standardised difference of DAS28 slopes, based on a linear mixed-effects model (equivalence interval set at ±30%). RESULTS: 64 and 73 patients were included in the S-arm and M-arm, respectively, which was less than planned. In the S-arm, TNF blockers were stopped for 39.1%, only tapered for 35.9% and maintained full dose for 20.3%. The equivalence was not demonstrated with a standardised difference of 19% (95% CI -5% to 46%). Relapse was more common in the S-arm (76.6% vs 46.5%, p=0.0004). However, there was no difference in structural damage progression. CONCLUSIONS: Tapering was not equivalent to maintenance strategy, resulting in more relapses without impacting structural damage progression. Further studies are needed to identify patients who could benefit from such a strategy associated with substantial cost savings.

IMPORTANCE: One-third of patients with rheumatoid arthritis show inadequate response to tumor necrosis factor α (TNF-α) inhibitors; little guidance on choosing the next treatment exists. OBJECTIVE: To compare the efficacy of a non-TNF-targeted biologic (non-TNF) vs a second anti-TNF drug for patients with insufficient response to a TNF inhibitor. DESIGN, SETTING, AND PARTICIPANTS: A total of 300 patients (conducted between 2009-2012) with rheumatoid arthritis, with persistent disease activity (disease activity score in 28 joints-erythrocyte sedimentation rate [DAS28-ESR] ≥ 3.2 [range, 0-9.3]) and an insufficient response to anti-TNF therapy were included in a 52-week multicenter, pragmatic, open-label randomized clinical trial. The final follow-up date was in August 2013. INTERVENTIONS: Patients were randomly assigned (1:1) to receive a non-TNF-targeted biologic agent or an anti-TNF that differed from their previous treatment. The choice of the biologic prescribed within each randomized group was left to the treating clinician. MAIN OUTCOMES AND MEASURES: The primary outcome was the proportion of patients with good or moderate response according to the European League Against Rheumatism (EULAR) scale at week 24. Secondary outcomes included the EULAR response at weeks 12 and 52; at weeks 12, 24, and 52; DAS28ESR, low disease activity (DAS28 ≤3.2), remission (DAS28 ≤2.6); serious adverse events; and serious infections. RESULTS: Of the 300 randomized patients (243 [83.2%] women; mean [SD] age, 57.1 [12.2] years; baseline DAS28-ESR, 5.1 [1.1]), 269 (89.7%) completed the study. At week 24, 101 of 146 patients (69%) in the non-TNF group and 76 (52%) in the second anti-TNF group achieved a good or moderate EULAR response (OR, 2.06; 95% CI, 1.27-3.37; P = .004, with imputation of missing data; absolute difference, 17.2%; 95% CI, 6.2% to 28.2%). The DAS28-ESR was lower in the non-TNF group than in the second anti-TNF group (mean difference adjusted for baseline differences, -0.43; 95% CI, -0.72 to -0.14; P = .004). At weeks 24 and 52, more patients in the non-TNF group vs the second anti-TNF group showed low disease activity (45% vs 28% at week 24; OR, 2.09; 95% CI, 1.27 to 3.43; P = .004 and 41% vs 23% at week 52; OR, 2.26; 95% CI, 1.33 to 3.86; P = .003). CONCLUSIONS AND RELEVANCE: Among patients with rheumatoid arthritis previously treated with anti-TNF drugs but with inadequate primary response, a non-TNF biologic agent was more effective in achieving a good or moderate disease activity response at 24 weeks than was the second anti-TNF medication.

BACKGROUND: Devil's claw (Harpagophytum procumbens), turmeric (Curcuma longa), and bromelain are nutraceuticals that have demonstrated anti-inflammatory and analgesic properties and may be potential solutions in the treatment of acute or chronic joint pain. Their analgesic effect, however, is generally considered mild to moderate, and the relevance of their clinical use remains subject to discussion. OBJECTIVES: The aim of the study was to evaluate the clinical relevance of the efficacy of a marketed complex of 3 plant extracts-H procumbens, C longa, and bromelain (AINAT, 650 mg)-in the treatment of degenerative joint pain. METHODS: A multicenter, observational, prospective, open-label survey was conducted in 8 rheumatology centers. The study included 2 groups, 1 group with participants suffering from chronic osteoarthritis (OA) pain and 1 group suffering from acute OA pain. SETTING: The research team carried out the study under daily practice conditions. PARTICIPANTS: A total of 42 patients (36 women; mean age = 67 y) suffering from acute or chronic, degenerative spine or joint pain participated. INTERVENTION: Two 650-mg capsules of AINAT were administered 3 ×/d to patients with acute pain and 2 ×/d to patients with chronic pain. OUTCOME MEASURES: At baseline, and during a follow-up visit at 15 d for the acute pain group and 60 d for the chronic pain group, the research team obtained each participant's global assessment (PGA) and each rheumatologist's global assessment (RGA), as well as each participant's pain score, using for each of them a 100-mm visual analogue scale (VAS). The clinical relevance of the efficacy was evaluated by comparing the outcome measures at endpoint to the values defining the patient acceptable symptom state (PASS) and by comparing the variations (in mm and %) between baseline and endpoint to those defining the minimal clinically important improvement (MCII). Tolerance was also assessed by collecting adverse events at each visit and by using a 4-point scale (very good to bad) at the endpoint. RESULTS: At baseline, the VAS pain score (standard deviation) was 69.1 mm (15.4) and 68.0 mm (18.2) for patients with acute and chronic pain, respectively. At the endpoint, the scores decreased to 42.1 mm (21.1) and 37.8 mm (25.9), respectively. This reduction of pain, as a percentage as well as an absolute value, corresponds to the required definition of MCII, particularly in patients with chronic joint pain. At the endpoint, most of the patients in both groups reached the level of pain defined as the PASS. No withdrawals occurred due to treatment side effects. CONCLUSION: The improvement of joint pain was clinically relevant in patients treated with AINAT for both acute and chronic OA pain. Considering its excellent tolerance profile, the tested complex of 3 plant extracts with antiinflammatory properties may be a valuable and safe alternative to NSAIDs in patients suffering from degenerative joint diseases.

BACKGROUND: Advanced radiological stage of knee osteoarthritis (OA) is predictive of poor response to viscosupplementation (VS). To date, the impact of x-ray features on the duration of effectiveness (DE) of VS has not been investigated. OBJECTIVES: To investigate the radiological features associated with DE of VS in patients with knee OA. METHODS: Cross-sectional study in patients with knee OA treated with 1 injection of cross-linked hyaluronic acid (HA). The primary outcome was DE, self-assessed by the patients in weeks of effectiveness. Radiological features (joint space narrowing-JSN topography and Kellgren-Lawrence [K-L] grade) associated with DE were studied. RESULTS: Fifty-one patients-33 females (76 knees)-were analyzed. The average DE was 52.0 (24.7) weeks (range, 13-155 weeks). In the bivariate analysis, DE was 14 weeks longer in those with K-L grades 1 and 2 (62.6 ± 36.4 weeks) than in those with K-L 3 and 4 (48.9 ± 18.6) (P = 0.03). DE was not significantly different according to the involved compartment(s). It was significantly longer in men than in women (60 ± 31.4 vs. 47 ± 16 weeks; P = 0.035). In multivariate analysis, K-L grade (1-2 vs. 3-4) (P = 0.007), male gender (0.02), and older age (0.04) were independently associated with a longer DE. CONCLUSION: DE of a single injection of extended-release HA is longer in K-L 1-2 than in K-L 3-4 OA knees, regardless of the JSN topography. However, even the patients with more advanced OA benefited from HANOX-M-XL injection for an average duration barely less than 1 year.

INTRODUCTION: Tocilizumab randomized clinical trial results are heterogeneous because of the heterogenous population included in them. METHODS: We conducted a meta-analysis with subgroup meta-analysis (PRISMA guidelines) between severe and non-severe COVID-19. RESULTS: We included nine trials. Overall, the mortality rate was 24.5% (821/3357) in the tocilizumab group and 29.1% (908/3125) in the control group at day 28-30 (pooled OR, 0.85; 95% CI 0.76-0.96; p = 0.006). Considering the subgroup analysis, this benefit on mortality was confirmed and amplified in the severe COVID-19 group (pooled OR, 0.82; 95% CI 0.73-0.93; p = 0.001) but not in the non-severe COVID-19 group (pooled OR, 1.46; 95% CI 0.91-2.34; p = 0.12). For patients who were not mechanically ventilated at baseline (5523/6482), the pooled OR (0.74; 95% CI 0.64-0.85; p < 0.0001) for mechanical ventilation incidence at day 28-30 was in favor of tocilizumab (cumulative incidence of 14.8% versus 19.4% in tocilizumab and control arm, respectively). This benefit was confirmed in both subgroups, i.e., severe and non-severe COVID-19. CONCLUSION: Tocilizumab is an effective treatment in hospitalized patients with COVID-19 and hypoxemia by improving survival and decreasing mechanical ventilation requirement. The greatest benefit is observed in severe COVID-19.
RESUMEN
COVID-19 patients (n = 34) suffering from ARDS were treated with tocilizumab (TCZ). Outcome was classified in two groups: "Death" and "Recovery". Predictive factors of mortality were studied. Mean age was 75.3, mean oxygen (O2) requirements 10.4 l/min. At baseline, all patients had multiple biological abnormalities (lymphopenia, increased CRP, ferritin, fibrinogen, D-dimer and liver enzymes). 24 patients (70.5%) recovered after TCZ therapy and 10 died (29.5%). Deceased subjects differed from patients in whom treatment was effective with regard to more pronounced lymphopenia (0.6 vs 1.0 G/l; p = 0.037), lower platelet number (156 vs 314 G/l; p = 0.0001), lower fibrinogen serum level (0.6 vs 1.0 G/l; p = 0.03), higher aspartate-amino-transferase (108 vs 57 UI/l; p = 0.05) and greater O2 requirements (11 vs 8 l/min; p = 0.003).

INTRODUCTION: No therapy has proven to be effective yet to reduce mortality and/or invasive mechanical ventilation (IMV) requirement in COVID-19. Tocilizumab (TCZ) in patients with severe COVID-19 could be an effective treatment. METHODS: We conducted a retrospective case-control study in the Nord Franche-Comté Hospital, France. We compared the outcome of patients treated with TCZ and patients without TCZ considering a combined primary endpoint: mortality and/or IMV requirement. RESULTS: Thirty patients were treated with TCZ and 176 patients were treated without TCZ. TCZ was used in patients in critical condition (oxygen therapy flow at TCZ onset was 10.5 L/min and 14/30 patients had ≥ 50% lung involvement on CT scan) as a rescue treatment (8/30 patients who died were not admitted in USC in regard to their comorbidities). However, mortality and/or IMV requirement were lower in patients with TCZ than in patients without TCZ (27% vs 52%, p = 0.009). CONCLUSION: Despite the small sample size in the TCZ group, this result suggests that TCZ reduces mortality and/or IMV requirement in patients with severe SARS-CoV-2 pneumonia. This notion needs to be confirmed and spread in the medical community.

Background: Osteoarthritis (OA) management needs a combination of nonpharmacological and pharmacological modalities. However, as in many chronic conditions, the main concern with OA therapy is the difficulty in obtaining good medication compliance over a long period. The PREDOA study aimed to investigate the predictive factors of adherence to treatment in patients with OA treated with glucosamine sulfate (GS)-copper sulfate-ginger root (GCu), a symptomatic slow-acting drug for OA. Methods: Ambulatory patients with a clinical diagnosis of OA were included in a prospective (6 months) multicenter open-label observational study. All patients received two capsules of GS-GCu once daily for 6 months. Demographics, disease features (OA location, symptom duration, concomitant therapies, comorbidities), and patient self-assessment of pain (0-10) were obtained at baseline. At month 6, the investigator collected patient self-assessments of treatment observance, reasons for nonadherence, pain scores, patient perceptions of treatment efficacy, changes in analgesic intake, and occurrence of adverse events. Predictors of observance were studied in univariate and multivariate analyses. Results: A total of 2,030 patients were included in the study. At baseline, the average pain score was 6.4±1.7. Observance was good in 80% of patients. It was weaker in active than retired patients (P=0.005) in patients not taking concomitant treatment (P=0.008) or who had never been treated for OA (P=0.001). Observance was correlated with pain decrease (P<0.0001) and with lack of adverse effects (P<0.001). Age, sex, pain level at baseline, OA location, and number of painful joints were not related to treatment compliance. Conclusion: Medication compliance with GS-GCu depends both on the safety-efficacy balance and several patient related-factors. To improve adherence, detailed information about therapeutic objectives is necessary in active patients who do not get any other medications and for whom it is their first treatment for OA. Clinical trial identifier: CCTIRS 14-371 B.
RESUMEN
BACKGROUND: To compare both safety and efficacy of a novel intra-articular viscosupplement made of intermediate molecular weight (MW) hyaluronic acid (HA) mixed with high concentration of mannitol with a marketed high MW HA, in patients with knee osteoarthritis (OA). METHODS: Patients with symptomatic knee OA, with radiological OARSI grades 1 to 3, were enrolled in a controlled, double-blind, parallel-group, non-inferiority trial. They were randomized to receive three intra-articular injections, at weekly intervals, of either HAnOX-M made of a combination of HA (MW one to 1.5MDa, 31mg/2ml) and mannitol (70mg/2ml) or Bio-HA (MW 2.3 to 3.6MDa, 20mg/2ml). The primary outcome was six-month change in the WOMAC pain subscale (0 to 20). Sample size was calculated according to a non-inferiority margin of 1.35. Secondary endpoints included six-month change in function and walking pain, analgesic consumption and safety. RESULTS: The intention-to-treat (ITT) and per-protocol (PP) populations consisted of 205 and 171 patients. HAnOX-M and Bio-Ha groups did not differ statistically at baseline. The primary analysis was conducted in the PP population, then in the ITT population. The average WOMAC pain score at baseline was 9.5 in both groups. Mean (SD) variations in WOMAC pain score were -4.4 (3.8) and -4.5 (4.3) mm, for HAnOX and Bio-HA respectively, satisfying the claim for non-inferiority. Similar results were obtained for all other secondary endpoints. CONCLUSION: Treatment with of HAnOX-M is effective to alleviate knee OA symptoms and to improve joint function over six months, with similar safety than conventional HA viscosupplement.

OBJECTIVES: The objective of this study is to obtain pilot data from daily practice conditions of a viscosupplement made of a cross-linked high-molecular-weight hyaluronic acid (HA) combined with mannitol in patients with knee osteoarthritis (KOA). METHODS: The data of 40 consecutive patients, 29 women and 11 men, who were prospectively followed up for 6 months, using a standardized procedure, were retrospectively analyzed. All patients have received a single intra-articular injection of HAnox-M-XL (4.4 mL), viscosupplement made of a cross-linked HA (16 mg/mL) + mannitol (35 mg/mL), in the target knee. The primary outcome was safety. The secondary end points included 3- and 6-month change in the WOMAC pain (0-50) and WOMAC total (0-240) and patient's global assessment (PGA). Patient's self-assessment of treatment efficacy (0-3) and analgesic consumption were obtained at months 3 and 6. An intent-to-treat analysis was performed. RESULTS: Mean (SD) age was 60.7 (13.9) years, and mean BMI was 28.6 (5.0). Kellgren-Lawrence radiological grade was I/II and III/IV in 13 and 27 of the subjects, respectively. The average WOMAC pain and WOMAC total scores at baseline were 21.5 (9.8) and 89.9 (42.8), respectively. Thirty-nine patients completed the follow-up. HAnox-M-XL was well tolerated; two patients experienced knee pain after injection, which resolved within three days. No treatment-related severe adverse event was reported. Mean (SD) variations in WOMAC pain and WOMAC total scores were -8.2 (8.9) and -38.4 (35.6), respectively, at month 6 (P = 0.001). PGA decreased from 5.5 (2.0) to 3.0 (2.2) (P = 0.006). Efficacy was rated as good or very good in 76.9% of the cases. Most of the regular analgesics users decreased their consumption. CONCLUSION: Treatment with one injection of 4.4 mL HAnox-M-XL is effective to alleviate KOA symptoms over six months, without safety concern. Controlled trials are needed to confirm these pilot data.
RESUMEN
This open-label, phase 3b study (ClinicalTrials.gov Identifier: NCT00983073) evaluated the effectiveness, and tolerability of tapentadol for severe, chronic osteoarthritis knee pain that was inadequately managed with World Health Organization (WHO) Step I or II analgesics or co-analgesics, or that was not treated with regular analgesics. Prior to starting study treatment, patients discontinued any WHO Step II analgesics, while Step I analgesics and/or co-analgesics were continued at the same dose. Patients received tapentadol prolonged release (50-250 mg bid) during a 5-week titration period and a 7-week maintenance period. Doses of tapentadol immediate release 50 mg (≤twice/day; ≥4 hours apart) were permitted throughout the study (total daily dose of tapentadol prolonged and immediate release, ≤250 mg bid). The primary endpoint was the change in pain intensity on an 11-point numerical rating scale-3 (NRS-3; recalled average pain intensity [11-point NRS] during the last 3 days) from baseline to Week 6, using the last observation carried forward (LOCF) to impute missing pain intensity scores. The mean (standard deviation) change from baseline to Week 6 (LOCF) in pain intensity was -3.4 (2.10; P < 0.0001) for all patients evaluated for effectiveness (n = 195). Significant decreases in pain intensity were also observed at Weeks 6, 8, and 12 (all P < 0.0001) using observed-case analysis. Corresponding significant improvements from baseline to Weeks 6 and 12 were observed in the Western Ontario and McMaster Universities osteoarthritis index, the EuroQol-5 Dimension health status questionnaire, the Short Form-36 health survey, and the Hospital Anxiety and Depression Scale (all P ≤ 0.0103). Treatment-emergent adverse events were in line with those observed in previous studies of tapentadol prolonged release. Overall, the results of this study indicate that tapentadol treatment results in significant improvements in pain intensity, health-related quality of life, and function in patients with inadequately managed, severe, chronic osteoarthritis knee pain.
RESUMEN
The aim of the study was to investigate the effect of hyaluronic acid (HA) intra articular injections (IA) on osteoarthritis (OA) biomarkers in patients with knee OA. Prospective open label study. Fifty-one patients with unilateral symptomatic K-OA received IA injections of 2mL of HA on days (D) 1, 7, 14 and were followed 3 months. At D-15 patients were examined and X-rays performed, to exclude patients with bilateral K-OA, or those with more than three symptomatic OA joints. From 15 days (D-15) before the first injection to D90 concomitant therapies were unchanged. Walking pain (WP) on VAS was obtained at each visit. Urine (U) and serum (S) samples were obtained at D-15, D1, D30, and D90. S-C2C, S-Cartilage oligomeric matrix protein, S-HA, S-CS 846 epitope, S-type II collagen propeptide, and U-type II collagen C telopeptide (U-CTX II/creatinin) were assayed. Predictive factors of response were analyzed using logistic regression. Correlations between variables were obtained using Spearman test. Forty-five patients were analyzed. Between D-15 and D1 there was no difference for any biomarkers At D1, WP (SD) was correlated with U-CTX II/creat (p = 0.006). Between D1 and D90: U-CTX II/creat decreased significantly. After adjustment for confounding variables there was a significant correlation between clinical response and U-CTX II/creat variation. U-CTX II and S-HA at baseline were independently predictive of clinical response. This study showed that 90 days after HA IA injections, U-CTX II levels significantly decrease compared to baseline, suggesting a slowdown of type II collagen degradation.

Aortitis due to giant cell arteritis (GCA) is rare but probably underestimated given the frequent paucity of symptoms. Thus, early studies relied on the occurrence of complications to estimate the prevalence of GCA aortitis. With this method, aortitis was a feature in 3 to 18% of GCA patients. Since then, the introduction of modern imaging techniques has established that aortitis is more common than previously thought. Aortitis should be considered in patients with atypical clinical presentations of GCA consisting, for instance, in isolated laboratory evidence of systemic inflammation or a relapse during treatment. Aortitis may be difficult to diagnose, as temporal artery biopsy has limited sensitivity in patients with predominant large-vessel involvement. Positron emission tomography (PET) and magnetic resonance imaging (MRI) are both highly effective for the early diagnosis of aortitis. Case-series evaluating PET in patients with GCA found evidence of aortitis in over half the cases, with predominant involvement of the thoracic aorta. To date, no evidence is available about the potential usefulness of PET or MRI in monitoring patients with GCA aortitis over time. Involvement of the aorta and other large arteries does not change the treatment strategy, which rests on corticosteroid therapy. Administration of a corticosteroid-sparing drug should be considered, most notably when a relapse occurs. Aortitis is associated with an increased risk of aneurysm of the thoracic aorta. Consequently, all GCA patients should be monitored for aneurysm at regular intervals, even after treatment discontinuation. The recommended strategy is an annual evaluation including a chest radiograph, echocardiogram, and abdominal Doppler sonogram; these imaging studies can be replaced by contrast-enhanced computed tomography of the chest and abdomen.

OBJECTIVES: To report our experience with rituximab therapy in patients with rheumatoid arthritis (RA) and a history of severe or recurrent bacterial infections. PATIENTS AND METHODS: Retrospective observational study in five rheumatology departments experienced in the use of biotherapies. Patients were included if they had RA and a history of severe or recurrent bacterial infection (requiring admission and/or intravenous antimicrobial therapy) that contraindicated the introduction or continuation of TNFalpha antagonist therapy. RESULTS: Of 161 RA patients given rituximab in the five study centers, 30 met the inclusion criteria, 23 females and seven males with a mean age of 58.4+/-11.8 years and a mean disease duration of 11.4+/-13.9 years. Among them, 22 had rheumatoid factors and 21 had received TNFalpha antagonist therapy (one agent in 15 patients, two in five patients and three in one patient). Prior infections were as follows: septicemia, n=2; lower respiratory tract infection or lung abscess, n=12; prosthesis infection, n=3; septic arthritis, n=3; endocarditis, n=1; pyelonephritis, n=2; osteitis, n=4; and various skin infections (erysipelas, cellulitis or skin abscess), n=6. Of these 33 infections, 21 occurred during TNFalpha antagonist therapy. During rituximab therapy, all patients received concomitant glucocorticoid therapy (mean dosage, 12+/-7.9 mg/day). The number of rituximab cycles was one in 13 patients, two in seven patients and three or more in 10 patients. Mean time from the single or last serious infection and the first rituximab infusion was 20.1+/-18.7 months. Mean follow-up since the first rituximab infusion was 19.3+/-7.4 months. During follow-up, six (20%) patients experienced one infection each. Immunoglobulin levels after rituximab therapy were within the normal range. CONCLUSION: Rituximab therapy was well tolerated in 24 (80%) of 30 patients with RA and a history of severe or recurrent bacterial infection. In everyday practice, rituximab therapy seems safe with regard to the recurrence of infectious episodes. However, longer follow-ups are needed.

UNLABELLED: The widespread use of TNFalpha antagonists in recent years has led to the recognition of paradoxical adverse effects, defined as the onset or exacerbation of disorders that are usually improved by TNFalpha antagonists. Cutaneous psoriasis is an example, of which several cases have been reported. OBJECTIVE: To identify cases of psoriasis onset or exacerbation during TNFalpha antagonist therapy and to look for potential predictive factors. METHODS: We retrospectively reviewed cases of psoriasis onset or exacerbation during TNFalpha antagonist therapy. For each case we recorded the following data: age, sex, underlying disease, nature of the TNFalpha antagonist, effectiveness in improving the underlying disease, history of psoriasis in the patient or family, time to psoriasis development, type of psoriasis (confirmed by an experienced dermatologist), concomitant treatments, whether the TNFalpha antagonist was stopped or continued, and the outcome of the psoriasis. These data were compared to those in the literature. RESULTS: We identified 12 patients, six men and six women, with a mean age of 45.5 years. The TNFalpha antagonist was adalimumab in four patients, etanercept in six patients, and infliximab in two patients. The underlying disease was ankylosing spondylitis in six cases, rheumatoid arthritis in four, and psoriatic arthritis in two. Mean time from treatment initiation to psoriasis was 4.1 months (range, 1-15 months). A previous history of psoriasis in the patient was noted in six cases, including four of the six patients taking etanercept. TNFalpha antagonist therapy was effective on the underlying disease in 11 of the 12 patients. The drug was discontinued in five patients, of whom four experienced resolution of their psoriasis. In the remaining seven patients, the drug was continued and the skin lesions remained unchanged. Most of the patients had psoriasis vulgaris (plaque psoriasis); palmoplantar pustulosis was a feature in five patients. DISCUSSION: Over 40 cases of psoriasis onset or exacerbation during TNFalpha antagonist therapy have been reported in the literature. The prevalence of this adverse effect has been estimated at 1.5-5% of patients taking TNFalpha antagonists. The findings from our case series are consistent with data in the literature. Psoriasis is a class effect that has been reported with all the currently available TNFalpha antagonists. The skin lesions develop within the first few months of therapy. Patients with a wide range of underlying diseases can be affected. Palmoplantar pustulosis is a common feature. A previous history of psoriasis seems more common in patients who experience psoriasis onset or exacerbation during etanercept therapy (four of six patients in our study and 55% in the literature); thus, previous psoriasis may be a risk factor for psoriasis exacerbation during etanercept therapy.
