Effect of Dysmetabolisms and Comorbidities on the Efficacy and Safety of Biological Therapy in Chronic Inflammatory Joint Diseases

In the present study we evaluated how systemic arterial hypertension (SAH), dyslipidemia and diabetes mellitus influence the efficacy, safety and retention rate of biological disease-modifying anti-rheumatic drug (bDMARD) treatment in rheumatic musculoskeletal disorders (RMDs). The charts of RMD patients treated with the first-line bDMARD were reviewed, collecting data on safety, efficacy and comorbidities at prescription (baseline, BL), after 6 months (6M) and at last observation on bDMARD (last observation time, LoT). In 383 RMD patients, a higher rate of adverse events at 6M (p = 0.0402) and at LoT (p = 0.0462) was present in dyslipidemic patients. Patients who developed dyslipidemia or SAH during bDMARD treatment had similar results (dyslipidemia p = 0.0007; SAH p = 0.0319) with a longer bDMARD retention as well (dyslipidemia p < 0.0001; SAH p < 0.0001). SAH patients on angiotensin converting enzyme inhibitors (ACEis) or angiotensin-II receptor blockers (ARBs) continued bDMARDs for longer than non-exposed patients (p = 0.001), with higher frequency of drug interruption for long-standing remission rather than inefficacy or adverse reactions (p = 0.0258). Similarly, dyslipidemic patients on statins had a better bDMARD retention than not-exposed patients (p = 0.0420). In conclusion, SAH and dyslipidemia may be associated with higher frequency of adverse events but a better drug retention of first-line bDMARD in RMDs, suggesting an additional effect of ACEis/ARBs or statins on the inflammatory process and supporting their use in RMD bDMARD patients with SAH/dyslipidemia.

Sirukumab for the treatment of rheumatoid arthritis: update on sirukumab, 2018

INTRODUCTION

Interleukin-6 (IL-6) is well-known for its pro-inflammatory properties, has been proven to target a wide range of cells in the joint, and has been implicated in extra-articular and articular manifestations in rheumatoid arthritis (RA). Tocilizumab (TCZ) is now widely used in patients with active RA and a number of additional agents that target the IL-6 pathways are under development, including sirukumab (SRK). Areas covered: SRK is an IgG1κ human anti-IL-6 monoclonal antibody which binds to IL-6 and prevents IL-6-mediated downstream effects. Initial trial results in phase-III studies in patients with RA seemed promising, showing improved results in patients with moderate-to-severe RA. Data derive from the phase-II study and the various SIRROUND studies (phase III). Expert commentary: The available data show that SRK50 mg every 4 weeks or 100 mg every 2 weeks will be effective in treating the RA population, with clinical improvements as early as week 2 and sustained over time. The adverse-event profile seems to be similar to TCZ, except for an increased mortality post open-label studies due to infections and cardiovascular events, our knowledge of which will be deepened with post-marketing surveillance and registry data.

The challenge of pet therapy in systemic sclerosis: evidence for an impact on pain, anxiety, neuroticism and social interaction

OBJECTIVES

The aim of our study was to evaluate the effect of animal-assisted intervention (AAI), a complementary support to traditional therapies focused on the interaction between animals and human beings, in improving psychological trait, anxiety and pain in a cohort of systemic sclerosis (SSc) patients.

METHODS

42 SSc patients, undergoing iloprost intravenous infusion, were divided in three groups: 1) 14 patients submitted to 20 AAI sessions; 2) 14 patients engaged in alternative social activity (control group 1 - C1); and 3) 14 patients without any alternative activity (control group 2 - C2). All patients underwent Visual Analog Scale (VAS), the State-anxiety (STAI-S) and emotional faces at the beginning (s0) and at the end (s1) of each single session, while General Anxiety State-Trait Anxiety Inventory (STAI-T), Beck Depression Inventory (BDI), Social Interaction Anxiety Scale (SIAS), Eysenck Personality Questionnaire-Revised (EPQ-R), the Social Phobia Scale (SPS), the Toronto Alexythymia Scale (TAS-20), the Thought Control Questionnaire (TCQ) were administered at baseline (t0) and at the end of the project (t1).

RESULTS

AAI group showed a significant decrease of the anxiety state level in respect to the two control groups (p<0.001). VAS scale resulted lower both in AAI (p < 0.001) and C1 group (p<0.01). Moreover, STAI-T and TAS scores were significantly reduced in AAI group (p<0.001). TCQ scale showed that patients treated with AAI, compared to control group C2, had greater capacity to avoid unpleasant and unwanted thoughts (p<0.05). In AAI group, the EPQ-R test revealed an enhancement of extroversion trait compared to both control groups (p<0.05).

CONCLUSIONS

Our data show that AAI significantly reduces pain perception, anxiety, neuroticism and ameliorates patients' social interaction, therefore it may be a useful to allow a better compliance to traditional therapies.

Role of Co-occurring Alcohol and Substances Abuse on QTc Interval Prolongation Among Psychiatric Patients: A Cross-sectional National Survey

Introduction

QTc interval prolongation is considered a risk factor for fatal polymorphic ventricular tachycardia, which can result in sudden cardiac death. Most psychotropic drugs have a dose-dependent potential to prolong the QTc interval. However, other factors require appropriate consideration, including: age; gender; other medications; electrolyte abnormalities; severe comorbid conditions, such as co-occurring alcohol or substances abuse/dependence.

Objectives

The objective was to study the potential mediating roles of alcohol/substances abuse on QTc prolongation.

Aims

The Italian research group STAR Network, in collaboration with the Young Italian Psychiatrists Association, aimed to evaluate the frequency of QTc interval prolongation in a sample of patients under treatment with psychotropic drugs through a cross-sectional national survey.

Methods

A sample of 2411 unselected patients were enrolled after performing an ECG during the recruitment period. Sociodemographic and clinical characteristics were collected from medical records. Collected data underwent statistical analysis.

Results

A total of 11.2% of patients reported alcohol abuse, and only 8.9% psychotropic substances. According to the threshold, less than 20% of patients had a borderline value of QTc, and 1% a pathological value. Patients with co-occurring alcohol misuse and drug abuse were more likely to have longer QTc interval.

Conclusions

The present study describes the frequency of QTc prolongation in real-world clinical practice. Before prescribing a psychotropic drug, the physician should carefully assess its risks and benefits to avoid this type of adverse reaction, particularly when additional risk factors are present. The potential role of alcohol and substances on QTc length could be particularly useful in emergency settings.

Calcinosis in poly-dermatomyositis: clinical and laboratory predictors and treatment options

OBJECTIVES

We aimed to identify the possible clinical and laboratory predictors of calcinosis in a cohort of patients with a diagnosis of polymyositis (PM) and dermatomyositis (DM).

METHODS

We carried out a retrospective analysis of a cohort of myositis patients attending our clinic between January 2013 and May 2014.

RESULTS

74 patients (58 females, 16 males) with PM (30 cases), DM (30 cases), overlap syndrome (13 cases) and inclusion body myositis (1 case) were enrolled. Sixteen patients (21.6%) had calcinosis that occurred a mean of 43.7 months after diagnosis of PDM. At multivariate analysis, patients with calcinosis experienced longer follow-up duration (p=0.006), anti-PM/Scl (p=0.033) and anti-NXP2 (p=0.024) positivity compared to patients without calcinosis. Furthermore, anti-NXP-2 positive C+ showed a diffuse form of calcinosis from the beginning and lower frequency of respiratory tract involvement. No single drug or associations of drugs was found effective in the treatment of calcinosis.

CONCLUSIONS

A longer follow-up period of time, DM diagnosis and positivity for PM/Scl and NXP-2 could all be considered risk factors which foresee the development of calcinosis. Moreover, the positivity for antibodies to NXP-2 depicts a distinct phenotype of calcinosis with an early onset and quick widespread dissemination.

Lidocaine controls pain and allows safe wound bed preparation and debridement of digital ulcers in systemic sclerosis: a retrospective study

In Systemic Sclerosis (SSc), digital ulcers (DU) are painful, difficult to heal, and frequently infected. To reduce the risk of bacterial infection and to prevent chronicity, it is essential to carefully remove necrotic tissue from DU, with maximum patient comfort. Debridement, although very efficacious, is invasive and causes local pain: lidocaine is a local anesthetic commonly used as to fight pain during debridement procedures. The aim of the study was to evaluate the efficacy of lidocaine 4 % in pain control during debridement procedure of DU in SSc. One hundred eight DU characterized by pain Numeric Rating Scale (NRS) >3/10 before starting the procedure were treated with lidocaine 4 % (lidocaine cloridrate 200 mg in 5 ml of injecting solution). Pain was measured with NRS (0-10) before starting debridement, after 15 min of lidocaine application and at the end of the procedure. In DU, in respect to baseline (mean NRS 6.74 ± 2.96), pain after application of lidocaine 4 % for 15 min was significantly lower (mean NRS 2.83 ± 2.73) (p < 0.001). At the end of the procedure, pain control was still maintained and significantly lower (mean NRS 2.88 ± 2.65) in respect to baseline (p < 0.001). No systemic adverse event due to topical lidocaine were observed. In SSc, topical application of lidocaine 4 % significantly reduces pain, allowing a safe debridement procedure, thus improving the management of DU.

Calcinosis in systemic sclerosis: subsets, distribution and complications

OBJECTIVE

To retrospectively analyse the features of calcinosis in a cohort of SSc patients.

METHODS

Charts of SSc patients attending the Ulcer Unit of the Rheumatology Department, University of Florence and presenting a clinical suspicion of calcinosis were considered in the study. Data on clinical history, including recent skin changes, and clinical examination of all areas with suspected calcinosis, radiological imaging of the calcinotic area, demographics and SSc-related organ involvement and pain measured by a visual analogue scale were recorded.

RESULTS

In 52 of 112 SSc patients, a total of 316 calcinoses were recorded and were divided into visible and palpable {154 [47.4%], clustered according to their macroscopic features as mousse [49 (31.8%)] and stone [: 105 (68.2%)]} and non-visible but palpable {: 162 [52.6%]: net [5 (3%)], plate [22 (13.8%)] and stone [135 (83.2%)]}. The X-ray-based classification of all calcinoses, both visible and non-visible, was as follows: stone, 289 (91.4%); net, 12 (3.8%) and plate, 15 (4.8%). Skin ulcers complicated 154 of 316 calcinoses (48.7%). Mousse calcinosis was associated with pulmonary arterial hypertension, the stone subset was suggestive of pulmonary involvement and justified further investigation and the net subset was the slowest to heal.

CONCLUSION

Our data indicate that calcinosis may be classified in SSc as mousse, stone, net and plate according to its clinical and X-ray features. This classification awaits validation for a possible use in clinical practice and to support early treatment and prevention of complications.

Assessment, Definition, and Classification of Lower Limb Ulcers in Systemic Sclerosis: A Challenge for the Rheumatologist

OBJECTIVE

To evaluate pathogenesis and clinical features of lower limb ulcers in systemic sclerosis (SSc) and to propose a classification that could be used in clinical practice.

METHODS

Charts of 60 patients with SSc who had lower limb cutaneous lesions were reviewed. All patients had videocapillaroscopy and arterial and venous lower limb color Doppler ultrasonography (US). Arteriography was performed if occlusive peripheral arterial disease was suspected.

RESULTS

The 554 lesions were classified as hyperkeratosis, ulcers, and gangrenes. There were 341 (61.6%) hyperkeratoses, 208 (37.5%) ulcers, and 5 (0.9%) gangrenes. Ulcers were divided into pure ulcers, ulcers associated with hyperkeratosis, and ulcers secondary to calcinosis. Involvement of arterial and venous macrocirculation as determined by color Doppler US was observed in 17 (18.3%) and 18 (30%) patients, respectively. Seventeen out of 37 patients with pure ulcers (45.9%) presented neither venous insufficiency nor hemodynamically significant macrovascular arterial disease. In these patients, pure ulcers were most likely caused by isolated SSc-related microvascular involvement (pure microvascular ulcers). The only significant risk factor for development of pure microvascular ulcers in the multivariate analysis was the history of lower limb ulcers (OR 26.67, 95% CI 2.75-259.28; p < 0.001).

CONCLUSION

Results of our study indicate that lower limb ulcers in SSc often have a multifactorial pathogenesis that may be difficult to manage. Further studies are needed to validate the proposed classification and to assess the most appropriate management of lower limb ulcers in SSc.

A cross-sectional nationwide survey on esophageal atresia and tracheoesophageal fistula

BACKGROUND

Our study aims at disclosing epidemiology and most relevant clinical features of esophageal atresia (EA) pointing to a model of multicentre collaboration.

METHODS

A detailed questionnaire was sent to all Italian Units of pediatric surgery in order to collect data of patients born with EA between January and December 2012. The results were crosschecked by matching date and place of birth of the patients with those of diagnosis-related group provided by the Italian Ministry of Health (MOH).

RESULTS

A total of 146 questionnaires were returned plus a further 32 patients reported in the MOH database. Basing on a total of 178 patients with EA born in Italy in 2012, the incidence of EA was calculated in 3.33 per 10,000 live births. Antenatal diagnosis was suspected in 29.5% patients. 55.5% showed associated anomalies. The most common type of EA was Gross type C (89%). Postoperative complications occurred in 37% of type C EA and 100% of type A EA. A 9.5% mortality rate was reported.

CONCLUSIONS

This is the first Italian cross-sectional nationwide survey on EA. We can now develop shared guidelines and provide more reliable prognostic expectations for our patients.

Digital ulcers as a sentinel sign for early internal organ involvement in very early systemic sclerosis

OBJECTIVE

The aim of this study was to evaluate the presence of digital lesions in very early diagnosis of SSc (VEDOSS) patients and its possible association with internal organ involvement.

METHODS

One hundred and ten VEDOSS patients were investigated for the presence of digital ulcers (DUs), digital pitting scars, calcinosis, necrosis or gangrene, nailfold videocapillaroscopic abnormalities, disease-specific autoantibodies (ACA and anti-topo I) and internal organ involvement.

RESULTS

Four patients reported a history of digital pitting scars, while 25 patients presented an active DU or reported a history of DUs. In particular, 16 patients presented with active DUs (14/16 also reporting a history of previous DUs), while the other 9 patients reported a history of DUs only. A statistically significant association between DUs and oesophageal manometry alteration was found in the whole DU population, as well as in the history of DU and the presence of active DU with/without a history of DU subgroups (P < 0.01, P = 0.01 and P < 0.05, respectively). DUs were observed in VEDOSS patients with internal organ involvement but not in those without organ involvement.

CONCLUSION

DUs are already present in VEDOSS patients characterized by internal organ involvement, significantly correlating and associating with gastrointestinal involvement. DUs may be a sentinel sign for early organ involvement in VEDOSS patients.

Neonatal laparoscopic inguinal hernia repair: a 3-year experience

PURPOSE

To retrospectively analyze the feasibility, safety and complication rate of laparoscopic inguinal herniorraphy in babies weighing 5 kg or less.

METHODS

Thirty infants weighing 5 kg or less underwent laparoscopic inguinal hernia repair during a 3-year period. Twenty-eight infants were born preterm and the mean body weight at surgery was 3,800 kg. Internal inguinal ring was closed with a non-absorbable purse-string suture. Contralateral processus vaginalis was closed if patent. Feeding was started on the same day and the patient discharged the following day. Follow-up consisted of physical examination at 1 week, 6 and 12 months post-operatively.

RESULTS

Of the 30 patients (27 males, 3 females), 11 had bilateral and 19 monolateral hernia (16 right, 3 left). At laparoscopy, 23 infants needed to have bilateral herniorraphies. The mean corrected gestational age at surgery was 49.1 weeks. The mean operative time for repair was 30 min for unilateral and 41 min for bilateral hernia. There were not intra- or post-operative complications as well as conversions or recurrences.

CONCLUSIONS

Laparoscopic inguinal hernia repair in newborns and in ex-preterm infants is a safe and effective procedure to perform and, perhaps, even less technically demanding than open herniotomy.
