Predictors of Mortality and Refracture in Patients Older Than 65 Years With a Proximal Femur Fracture.

OBJECTIVES: To evaluate potential predictors of subsequent fracture and increased mortality in a population 65 years or older who suffered a proximal femur fragility fracture. METHODS: This was a longitudinal study that included patients with a proximal femur fragility fracture, referred from the Orthopedics Inpatient Department to the Rheumatology Department's Fracture Liaison Service, from March 2015 to March 2017. RESULTS: Five hundred twenty-two patients were included, with a median age (IQR) of 84 years (interquartile range [IQR], 11 years), 79.7% (n = 416) female. Nine percent (n = 47) suffered a new fracture, with a median time to event of 298 days (IQR, 331 days). Cumulative probability without refracture at 12 months was 93% (95% confidence interval [CI], 90.2%-95.0%); 22.8% (n = 119) patients died, with median time to death of 126 days (IQR, 336 days). Cumulative survival probability at 12 months was 81.7 (95% CI, 77.9-84.8). Neurologic disease (hazard ratio [HR], 2.30; 95% CI, 0.97-5.50; p = 0.06) and chronic obstructive pulmonary disease (HR, 3.61; 95% CI, 1.20-10.9; p = 0.022) were both predictors of refracture. Age older than 80 years (HR, 1.54; 95% CI, 0.99-2.38; p = 0.052), higher degree of dependence (HR, 1.24;95% CI, 1.09-1.42; p = 0.001), male sex (HR, 1.55; 95% CI, 1.03-2.33; p = 0.034), femoral neck fracture (HR, 0.45; 95% CI, 0.24-0.88; p = 0.018), Charlson score (HR, 2.08; 95% CI, 1.17-3.69; p = 0.012), heart failure (HR, 2.44; 95% CI, 1.06-5.63; p = 0.037), hip bone mass density (HR, 3.99; 95% CI, 1.19-13.4; p = 0.025), hip T score (HR, 0.64; 95% CI, 0.44-0.93; p = 0.021), and ß-crosslaps (HR, 1.98; 95% CI, 1.02-3.84; p = 0.042) all predicted a higher mortality. CONCLUSIONS: Neurologic disease and chronic obstructive pulmonary disease may increase the risk of subsequent fracture after a hip fracture. Male sex, age, autonomy degree, femur bone mass density/T score, fracture type, Charlson score, diabetes mellitus, heart failure, and ß-crosslaps had significant impact on survival. The authors highlight ß-crosslaps as a potential serological marker of increased mortality in clinical practice.

Application of the new PRINTO classification criteria for juvenile idiopathic arthritis in a sample of Portuguese patients.

BACKGROUND: The International League of Associations for Rheumatology (ILAR) classification system for juvenile idiopathic arthritis (JIA) does not depict homogenous subgroups of disease. As to unify our language with the adult rheumatic diseases, the Pediatric Rheumatology International Trials Organization (PRINTO) is attempting to revise these criteria. OBJECTIVE: To reclassify a JIA sample according to the new provisional PRINTO subsets: systemic JIA (sJIA), RF-positive JIA (RF-JIA), early-onset ANA-positive JIA (eoANA-JIA), enthesitis/spondylitis-related JIA (ESR-JIA), "other JIA" and "unclassified JIA". METHODS: Retrospective study including JIA patients followed in a Pediatric Rheumatology Unit at a university hospital. Medical records were reviewed, and patients were reclassified as per the provisional PRINTO criteria. RESULTS: Of a total of 104 patients, 41 (39.4%) were reclassified as "other JIA", 36 (34.6%) as eoANA-JIA, 15 (14.4%) as ESR-JIA, 8 (7.7%) as sJIA and 4 (3.8%) as RF-JIA. More than 90% of the oligoarticular JIA were reclassified into either eoANA-JIA or "other JIA". Only one negative RF polyarticular JIA converted to RF-JIA due to the presence of a positive anti-citrulinated peptide antibody (ACPA). The psoriatic arthritis (PsA) subgroup disappeared into eoANA-JIA (25%), ESR-JIA (25%) or "other JIA" (50%). There were significant differences in age of onset, but not on the gender ratio or uveitis presence. Antinuclear antibody was more frequent in females (p=0.035) and younger patients (p<0.001). CONCLUSION: The number of affected joints and PsA features elapsed in favour of laboratory RF, ACPA and ANA traits. PsA and oligoarticular JIA were abolished. The "other JIA" entity is heterogenous and prevalent, claiming reformulation.

Preconception counseling impact in pregnancy outcomes in patients with spondyloarthritis.

INTRODUCTION: Spondyloarthritis (SpA) is a group of chronic inflammatory diseases, often affecting women in reproductive age. These diseases can have a significant impact on the reproductive health of women. Preconception counseling and medication adjustments have shown to reduce flares and improve pregnancy outcomes in women with rheumatoid arthritis. However, in women with SpA data of the impact of preconception counselling on pregnancy outcomes is scarce. The aim of this study is to evaluate that. METHODS: In this retrospective multicentric study, data was collected from medical records of women who gave birth from 2020 to 2022. The study included 45 pregnancies, which were divided into two categories whether they received preconception consultation or not. Data was collected on patient characteristics, disease duration, medications used, and preconception counselling. Outcomes were divided into two groups: maternal and fetal outcomes. RESULTS: 30 out of 45 pregnancies (66.67%) had received preconception counselling, having a significantly lower percentage of flares occurring postpartum compared to the non-counselling group (36.6% vs 6.4%, p=0.031) and lower percentage of contraindicated medication during pregnancy (20.0 vs 0.0%, p=0.011). CONCLUSION: Preconception counselling in women with SpA can increase the likelihood of medication adjustments before pregnancy and decrease the occurrence of flares postpartum. These findings suggest that preconception counselling should be implemented in the management of pregnant women with SpA to improve pregnancy outcomes. Further studies are needed to confirm the effectiveness of preconception counselling and to determine the optimal approach.

Touraine-Solente-Gole syndrome: pathogenic variant in SLCO2A1 presented with polyarthralgia and digital clubbing.

BACKGROUND: Primary Hypertrophic Osteoarthropathy (PHO), also known as Touraine-Solente-Gole Syndrome, is a rare, multisystemic autosomal recessive disorder caused by pathogenic variants in the 15-hydroxyprostaglandin dehydrogenase (HPGD) or Solute Carrier Organic Anion Transporter Family Member 2A1 (SLCO2A1) genes. However, autosomal dominant transmission has also been described in some families with incomplete penetrance. PHO usually starts in childhood or adolescence, presenting with digital clubbing, osteoarthropathy, and pachydermia. We described a complete form of the syndrome in a male patient with a homozygous variant in the SLCO2A1 gene (c.1259G > T). CASE PRESENTATION: A 20-year-old male was referred to our Pediatric Rheumatology Clinic with a five-year history of painful and swollen hands, knees, ankles and feet, prolonged morning stiffness and relief with non-steroidal antiinflammatory drugs. He also reported late onset facial acne and palmoplantar hyperhidrosis. Family history was irrelevant and parents were non-consanguineous. On clinical examination, he presented clubbing of the fingers and toes, moderate acne and marked facial skin thickening with prominent scalp folds. He had hand, knee, ankles and feet swelling. Laboratory investigations showed elevated inflammatory markers. Complete blood count, renal and hepatic function, bone biochemistry were normal, as well as immunological panel. Plain radiographs revealed soft tissue swelling, periosteal ossification and cortical thickening of the skull, phalanges, femur and toe acroosteolysis. Due to the absence of other clinical signs suggesting a secondary cause, we suspected PHO. A genetic study revealed a likely pathogenic variant, c.1259G > T(p.Cys420Phe), in homozygosity in the SLCO2A1 gene, thus confirming the diagnosis. The patient started oral naproxen with significant clinical improvement. CONCLUSIONS: PHO should be kept in the differential diagnosis of inflammatory arthritis affecting children, often misdiagnosed as Juvenile Idiopathic Arthritis (JIA). To the best of our knowledge, this is the second genetically confirmed case of PHO in a Portuguese patient (first variant c.644 C > T), both made at our department.

Anakinra and hepatotoxicity in pediatric rheumatology: a case series.

BACKGROUND: Anakinra is a recombinant interleukin-1 (IL-1) receptor antagonist used in systemic juvenile idiopathic arthritis (sJIA), refractory Kawasaki disease (KD) and cryopyrin-associated autoinflammatory syndrome (CAPS). Anakinra associated hepatotoxicity, while rare, has been described in several cases in daily practice. ​In this case series the authors describe three pediatric patients with this side effect in the setting of severe macrophage activation syndrome (MAS) in KD and sJIA. CASE PRESENTATION: The first patient was a 12-year-old boy who presented with fever, maculo-papular exanthema and polyarthralgia. Tonsillitis, distal limb induration and tender cervical lymph nodes were observed. Erythrocyte-sedimentation rate (ESR), C-reactive protein (CRP), ferritin (11,975 ng/mL), D-dimers (5,98 mg/L FEU) and soluble CD25 (3645 pg/mL) levels were elevated. Exclusion of sepsis / toxic shock syndrome warranted introduction of IV methylprednisolone and immunoglobulin (IG IV), with partial response. A MAS secondary to KD was assumed, and anakinra 2 mg/kg/day was introduced. Twenty days later he developed new-onset nausea and severe cyto-cholestasis, normalizing after 2 months of drug discontinuation. Posterior onset of polyarthritis and evanescent lead to a final diagnosis of sJIA. The second patient was a 2-year-old boy with a 10-day history of fevers, generalized rash, hepatosplenomegaly and strawberry tongue. Leucocytosis with neutrophilia and elevated CRP were observed. Initial treatment with IVIG in the setting of incomplete KD was ineffective. Mild anaemia, leukopenia and very high serum ferritin (maximum 26,128 ng/mL) ensued. Presumptive sJIA associated MAS was treated with IV methylprednisolone and anakinra 2 mg/kg/day, with prompt response. Four weeks later transaminitis was detected, and temporary anakinra suspension led to normalisation of laboratorial values. The third case related to a 4-year-old boy presenting with fever, maculopapular rash and cervical lymphadenopathy. CRP and ESR were elevated, and KD was diagnosed. IVIG and methylprednisolone were initiated with clinical worsening, warranting for anakinra introduction at 2 mg/kg/day. After three weeks, liver enzymes progressively elevated, resolving on 2 weeks of anakinra discontinuation. CONCLUSIONS: To the best of our knowledge, this is the first case series describing anakinra associated hepatotoxicity in pediatric patients with rheumatic diseases other than sJIA, bringing additional insight to therapeutic monitoring in patients undergoing this treatment.

Bone mineral density and fracture risk in a cohort of Portuguese systemic sclerosis patients.

Patients with Systemic Sclerosis (SSc) seem to have higher prevalence of low bone mineral density (BMD) and spine fracture risk. We performed a transversal study including patients with the diagnosis of SSc to determine, by conventional densitometry and using the fracture risk assessment tool (FRAX), the prevalence of low BMD and the fracture risk, respectively, in a SSc Portuguese cohort and its potential determinants. Ninety-seven patients were included; 88.7% females (n=86) with median age of 62 years [56, 70]. Low BMD was present in 45 patients (46.4%). BMD in the femoral neck (FN) presented a weak positive correlation with body mass index (BMI) and the risk for major fracture with and without BMD presented a positive correlation with spine fractures. No correlations were found between BMD-FN and disease manifestations. Our results showed that low BMD is prevalent in SSc patients and may be associated with low BMI. FRAX appears to be an useful instrument as it correlates with spine fracture risk and with BMD. This is the first study in Portugal evaluating prevalence of low BMD and fracture risk in a Portuguese SSc cohort.

Kidney Function, Age, and Education as Contributors to Depression and Anxiety in Juvenile Systemic Lupus Erythematosus.

Juvenile systemic lupus erythematosus (JSLE) is diagnosed in children younger than 18 years of age. Depression and anxiety are common, but not well understood in JSLE. We investigated the clinical and psychological factors associated with the psychological manifestations of JSLE. Twenty-nine JSLE patients were recruited for the study. Patients completed surveys evaluating their psychological status and perceptions about their health. Medical records were used to obtain laboratory results. The JSLE patient population was compared with adult-onset SLE (ASLE) patients and unaffected controls. Kidney involvement was associated with depression in the JSLE patients. The BUN levels, BUN/creatinine ratio, and leukocyturia were all significantly associated with depressive symptoms. Multivariate analysis found that the BUN/creatinine ratio was the most predictive value for both depression and anxiety. Depressive symptoms in JSLE were less pronounced than in ASLE, although anxiety was not different. Age and education are likely to be protective against depression in the JSLE patients. These findings may indicate that symptomatology is an important indicator of whether the patient needs psychiatric care.

Safety considerations when using drugs in pregnant patients with systemic lupus erythematosus.

Introduction: Systemic lupus erythematosus (SLE) mainly affects young females during childbearing age; therefore, reproductive issues are of major interest.Areas covered: Pregnancy planning is crucial to adjust the treatment toward drugs that are safe throughout pregnancy and breastfeeding. The evidence about drug safety is limited to post-marketing surveillance, registries, case series, and case reports, as pregnant patients are excluded from randomized clinical trials. The aim of this review is to report the safety considerations when treating pregnant SLE patients. Regarding maternal side effects of drugs, we focused on metabolic, infectious, and hemorrhagic complications. Fetal safety was analyzed looking at drugs teratogenicity, their possible effects on immune system, and on the long-term neuropsychological development of children.Expert opinion: The management of pregnancy in SLE has changed when knowledge about the safety of drugs has become available. Keeping SLE disease activity under control before, during and after pregnancy is of fundamental importance to ensure the best possible outcomes for mother and child. All these issues must be discussed with the patient and her family during preconception counseling. International efforts in terms of pregnancy registries and reproductive health guidelines help physicians improve their communication with SLE patients.

Maternal, pregnancy and neonatal outcomes of twin gestations in women with rheumatic diseases: A single-center, case-control study.

OBJECTIVE: To assess maternal, pregnancy and neonatal outcomes of twin pregnancy (TP) in women with rheumatic diseases (RD) (Group A) as compared to those of singleton pregnancy (SP) in women with RD (Group B) and TP in the general obstetric population (GOP) (Group C). METHODS: Case-control study including TP in RD during the period 2009-2020 at single institution. Women in Group A were matched with women of the same age at conception and affected by the same RD (Group B). Women in Group A and C were also matched. RESULTS: Fifty-three women with RD (13 in Group A and 40 in Group B) and 39 healthy controls were included. RD was quiescent in 85% of patients in both Groups A and B. Spontaneous conception was more frequent in Group B (98%), as compared to A (62%) (p = 0.002). Emergency cesarean section and premature delivery were more frequent in Group A as compared to B and C (54% vs 15% vs 23%, p = 0.008, 69% vs 13% vs 39%, p < 0.000 and p = 0.054, respectively). Five babies (21%) in Group A required admission to the neonatal intensive care unit (NICU), but none in Group B (p = 0.007). CONCLUSION: This is the first case-control study assessing the outcomes of TP in women with RD. An increased risk of preterm delivery, emergency cesarean section and admission to NICU as compared to both SP in RD and TP in the GOP was observed. Multidisciplinary management is warranted to minimize these risks.

Two cases of ADA2 deficiency presenting as childhood polyarteritis nodosa: novel ADA2 variant, atypical CNS manifestations, and literature review.

Deficiency of adenosine deaminase 2 (DADA2) is an autosomal recessive disease resulting from loss-of-function pathogenic variants in ADA2 gene, which might resemble polyarteritis nodosa (PAN). The authors present two pediatric cases of ADA2 deficiency with phenotypic manifestations of PAN, including an unusual presentation with spinal cord ischemia. Also described is an assessment of ADA2 activity and gene expression profiling with description of a previously unreported homozygous variant, c.1226C > A (p.(Pro409His)), detected in a patient with consanguineous parents, confirmed by near-absent ADA2 plasma enzymatic activity. The authors suggest to first obtain enzymatic activity, whenever DADA2 is suspected, before proceeding to genetic testing, due to its excellent cost-effective results. Moreover, physicians must be aware of this monogenic disorder, especially in the case of early-onset PAN-like manifestations, having a family member with similar manifestations or having consanguineous parents suggesting an autosomal recessive inheritance pattern. Given the multi-organ involvement, recognizing the diverse manifestations is a crucial step towards timely diagnosis and management of this potentially fatal but often treatable syndrome.

Remission and low disease activity matrix tools: results in real-world rheumatoid arthritis patients under anti-TNF therapy.

BACKGROUND: Remission/ low disease activity (LDA) are the main treatment goals in rheumatoid arthritis (RA) patients. Two tools showing the ability to predict golimumab treatment outcomes in patients with RA were published. OBJECTIVES: To estimate the real-world accuracy of two quantitative tools created to predict RA remission and low disease activity. METHODS: Multicenter, observational study, using data from the Rheumatic Diseases Portuguese Register (Reuma.pt), including biologic naïve RA patients who started an anti-TNF as first-line biologic and with at least 6 months of follow-up. The accuracy of two matrices tools was assessed by likelihood-ratios (LR), sensitivity (SN), specificity (SP), positive predictive value (PPV), negative predictive value (NPV) and area under the ROC curve (AUC). RESULTS: 674 RA patients under first-line anti-TNF (266 etanercept, 186 infliximab, 131 adalimumab, 85 golimumab, 6 certolizumab pegol) were included. The median (IQR) age was 53.4 (44.7-61.1) years and the median disease duration was 7.7 (3.7-14.6) years. The majority were female (72%). Most patients were RF and/or ACPA positive (75.5%) and had erosive disease (54.9%); 58.6% had comorbidities. At 6-months, 157 (23.3%) patients achieved remission (DAS28 ESR < 2.6) and 269 (39.9%) LDA (DAS28 ESR ≤ 3.2). Area under the curve for remission in this real-world sample was 0.756 [IC 95% (0.713-0.799)] and for LDA was 0.724 [IC 95% (0.686 -0.763)]. The highest LR (8.23) for remission state was obtained at a cut-off ≥ 67%, with high specificity (SP) (99.6%) but low sensitivity (SN) (3.2%). A better balance of SN and SP (65.6% and 73.9%, respectively) was observed for a cut-off >30%, with a LR of 2.51, PPV of 43.3% and NPV of 87.6%. CONCLUSION: In this population, the accuracy of the prediction tool was good for remission and LDA. Our results corroborate the idea that these matrix tools could be helpful to select patients for anti-TNF therapy.

First steps to understand productivity loss in Portuguese patients with rheumatoid arthritis.

Rheumatoid Arthritis (RA), in consequence of joint inflammation and damage, is known to lead to productivity loss. Developments during the 21st century, such as biologic treatments, allowed remission/low disease activity to be achieved in more RA patients. Despite this, evidence is equivocal concerning work outcomes improvement. Our goal was to evaluate work status and productivity in a Portuguese population with RA from 3 Rheumatology Departments through the questionnaire Work Productivity and Activity Impairment General Health (WPAI).

Osteopoikilosis: case series from Portuguese Rheumatology Centers.

Osteopoikilosis (OPK) is a rare, hereditary, usually asymptomatic disease characterized by the presence of multiple, well-defined sclerotic lesions distributed in peri-articular locations, frequently diagnosed as an incidental finding. Differential diagnosis with osteoblastic metastases is fundamental. This article reports six cases of OPK diagnosed in Portuguese Rheumatology Centers.

Biologic therapy use and pregnancy outcomes in women with immune-mediated inflammatory rheumatic diseases.

INTRODUCTION: Concerns about the side effects and interactions of biologic drugs with reproduction and pregnancy have been always an issue between experts. The safety of these therapies during conception and/or pregnancy is not fully understood. The aim of this study was to assess the exposure to biologic drugs before and/or during conception/pregnancy and the risk of adverse pregnancy outcomes in women with rheumatic diseases. METHODS: We conducted a cohort study of pregnancies reported in women with immune-mediated rheumatic diseases registered at the Rheumatic Diseases Portuguese Registry (Reuma.pt) and exposed to biologic drugs. Data concerning fetal and maternal outcomes (live birth, spontaneous abortion, neonatal and intrauterine death, intrauterine growth restriction, premature delivery, congenital malformations, neonatal lupus, voluntary or medical interruption of pregnancy, disease flares and need for treatment with other drugs) was extracted. RESULTS: In total, 69 pregnancies from 56 females were analysed, the majority with the diagnosis of spondyloarthritis or rheumatoid arthritis. In almost half of the cases (n=32, 46.4%) the biologic was stopped for pregnancy planning, in 31 cases (44.9%) it was stopped when pregnancy was diagnosed and in 6 pregnancies (8.7%) biologic therapy was maintained, at least until the 2nd trimester. There were 76.8% of live births and 22% of spontaneous abortions. Congenital anomalies were reported in 2 newborns. CONCLUSIONS: In half cases, it was decided to stop biologic therapy in the family planning period. Using biologic disease-modifying anti-rheumatic drugs before and/or during pregnancy doesn't seem to affect the overall maternal and fetal outcomes. Pregnancy planning and treatment options should be discussed and a shared decision should be established between physician and patient.

Tocilizumab and rituximab have similar effectiveness and are both superior to a second tumour necrosis factor inhibitor in rheumatoid arthritis patients who discontinued a first TNF inhibitor.

OBJECTIVES: To compare the effectiveness of a 2nd TNF inhibitor (TNFi), Tocilizumab (TCZ) and Rituximab (RTX), measured by drug retention and by response rates, in RA patients after discontinuing a first-line TNFi and to clarify the reasons and predictors for discontinuation of a second-line biologic. MATERIAL AND METHODS: Non-interventional prospective study of RA patients exposed to a 2nd TNFi, TCZ or RTX after previous TNFi discontinuation using real-world data from Reuma.pt database. Drug retention was estimated using Kaplan-Meier analysis and Cox models. Crude and LUNDEX adjusted response rates were evaluated at 6 months, 1 and 2 years and reasons for discontinuation were compared according to biologic class. RESULTS: In total, 643 patients were included, 88.8% females, with a mean age of 59.4±12.8 years. Of those, 390 (60.7%) initiated a 2nd TNFi, 147 (22.9%) TCZ and 106 (16.5%) RTX. Drug retention was significantly greater among patients who initiated TCZ (76.4±4.3 months) or RTX (80.8±4.8 months), compared with those who initiated a 2nd TNFi (52.7±2.6 months) (log rank test, p < 0.001). In the adjusted Cox model, hazards of discontinuation were significantly lower for TCZ (HR 0.39, 95% CI 0.23-0.64, p < 0.001) and RTX (HR 0.42, 95% CI 0.25-0.72, p=0.001). Smokers had a significantly higher risk for discontinuation (HR 2.43, 95%CI 1.50-3.95, p < 0.001) as well as patients with higher HAQ at baseline (HR 1.51, 95%CI 1.14-2.00, p=0.004). The proportion of patients in remission or low disease activity according to Clinical Disease Activity Index (CDAI) at 6 months, 1 and 2 years was, respectively, 46.5%/50.0%/61.2% for TNFi, 52.9%/53.6%/ 69.2% for TCZ and 37.7%/48.0%/50.0% for RTX. After LUNDEX adjustment, response rates were, respectively, 33.0%/31.0%/31.8% for 2nd TNFi, 42.8%/41.8%/53.3% for TCZ and 32.0%/39.4%/39.0% for RTX. The main reasons for discontinuation were inefficacy for 2nd TNFi and RTX and adverse events for TCZ (p < 0.001). CONCLUSIONS: Our findings showed a significantly higher drug retention for TCZ and RTX, compared with 2nd TNFi, and similar persistence among TCZ and RTX, in patients who discontinued a first-line TNFi. These data corroborate the notion that switching to a biologic with a different mode of action is more effective than to a second TNFi.
