Outcomes in progressive systemic sclerosis treated with autologous hematopoietic stem cell transplantation compared with combination therapy.

OBJECTIVES: Autologous hematopoietic stem cell transplantation (AHSCT) has been shown to improve long-term survival for early diffuse progressive systemic sclerosis (SSc) compared with cyclophosphamide. Cyclophosphamide, however, does not provide a long-term benefit in SSc. The combination of mycophenolate mofetil (MMF) and rituximab is a potent alternative regimen. We aimed to retrospectively compare the outcomes of SSc patients who underwent AHSCT to patients who met the eligibility criteria for AHSCT but received upfront combination therapy with MMF and rituximab. METHODS: Repeated assessments of modified Rodnan Skin Score (mRSS), forced vital capacity (FVC), and diffusing capacity (DLCO) values were conducted. Clinical improvement was defined as an mRSS decrease > 25% or an FVC increase > 10%. Event-free survival (EFS) was defined in the absence of persistent major organ failure or death. RESULTS: Twenty-one SSc patients in the combination therapy group were compared with sixteen in the AHSCT group. Age, sex and disease duration were similar between the two groups. Clinical improvement at 12 months was seen in 18 (86%) patients in the combination group compared with 13 (81%) in the AHSCT group (p= 0.7). The hazard ratio for EFS at 24 months favored the combination group (HR = 0.09, P= 0.04). During follow-up, both groups exhibited a significant and comparable reduction in mRSS and an increase in FVC values at each time interval up to 24 months. CONCLUSION: MMF and rituximab compared with AHSCT in SSc patients eligible for AHSCT resulted in similar skin and lung clinical improvement with a better safety profile at 24 months.

Factors associated with drug survival on first biologic therapy in patients with rheumatoid arthritis: a population-based cohort study.

Lack of sufficient head-to-head trials comparing biologic disease-modifying antirheumatic drugs (bDMARDs) in rheumatoid arthritis (RA), makes the choice of the first bDMARD a matter of rheumatologist's preference. Longer drug survival on the first bDMARD usually correlates with early remission. We aimed to identify factors associated with longer drug survival. We conducted a population-based retrospective longitudinal cohort study. We identified RA patients using the relevant International Classification of Disease 9th codes. "True" RA patients were defined as patients fulfilling, additionally, at least one of the following: receiving conventional DMARDs (cDMARDs), being positive for rheumatoid factor or anti-cyclic citrullinated peptide, or being diagnosed by a rheumatologist. We compared drug survival times and identified factors associated with longer drug survival. We identified 4268 true RA patients between the years of 2000-2017. 820 patients (19.2%) received at least one bDMARD. The most commonly prescribed bDMARDs were etanercept (352, 42.9%), adalimumab (143, 17.4%), infliximab (142, 17.3%) and tocilizumab (58, 7.1%). Infliximab was associated with the longest drug survival (47.1 months ± 46.3) while golimumab was associated with the shortest drug survival (14.9 months ± 15.1). Male gender [hazard ratio (HR) = 0.76, 95% confidence interval (CI), 0.63-0.86, p = 0.001], concurrent conventional DMARDs use (HR = 0.79, 95% CI 0.68 - 0.98, p = .031) and initiating bDMARD therapy in earlier calendric years (HR = 1.12, 95% CI 1.10 -1.18, p = 0.0001) were associated with longer drug survival. Male gender, concomitant cDMARDs and initiating biologic therapy at earlier calendric years are associated with longer drug survival.

The association between serum magnesium levels and community-acquired pneumonia 30-day mortality.

BACKGROUND: Community acquired pneumonia (CAP) is a common illness affecting hundreds of millions worldwide. Few studies have investigated the relationship between serum magnesium levels and outcomes of these patients. We aimed to study the association between serum magnesium levels and 30-day mortality among patients with CAP. METHODS: Retrospective overview of patients hospitalized with CAP between January 1, 2010 and December 31, 2016. Participants were analyzed retrospectively in order to identify the risk factors for a primary endpoint of 30-day mortality. Normal levels of magnesium levels in our laboratory varies between 1.35 and 2.4 mg/dl. RESULTS: 3851 patients were included in our cohort. Age > 75 years, blood urea nitrogen (BUN) > 20 mg/dl, hypoalbuminemia, and abnormal levels of magnesium were all associated with increased risk of 30-day mortality. Normal magnesium levels were associated with the lowest mortality rate (14.7%). Notably, within the normal levels, high normal magnesium levels (2-2.4 mg/dl) were correlated with higher mortality rates (30.3%) as compared to levels that ranged between 1.35-2 mg/dl (12.9%). Hypomagnesemia and hypermagnesemia were both associated with excess of 30-day mortality, 18.4 and 50%, respectively. CONCLUSION: Hypomagnesemia and hypermagnesemia on admission were associated with an increased rate of 30-day mortality among adult patients hospitalized with CAP. Interestingly, magnesium levels within the upper normal limits were associated with higher mortality.

Serum inorganic phosphorus levels predict 30-day mortality in patients with community acquired pneumonia.

BACKGROUND: Community acquired pneumonia is a major cause of morbidity and mortality. The association between serum phosphorus levels on admission and the outcome of patients with community acquired pneumonia has not been widely examined. We aimed to investigate the prognostic value of serum phosphorus levels on admission on the 30- day mortality. METHODS: The cohort included patients of 18 years old or older who were diagnosed with community acquired pneumonia between 2006 and 2012. Patients were retrospectively analyzed to identify risk factors for a primary endpoint of 30-day mortality. Binary logistic regression analysis was used for the calculation of the odds ratios (OR) and p values in bivariate and multivariate analysis to identify association between patients' characteristic and 30-day mortality. RESULTS: The cohort included 3894 patients. In multivariate regression analysis, variables associated with increased risk of 30-day mortality included: age >80 years, increased CURB-65 score, RDW >15, hypernatremia >150 mmol/l, hypoalbuminemia <2 gr/dl and abnormal levels of phosphorus. Levels of <1.5 mg/dl and >4.5 mg/dl were significantly associated with excess 30-day mortality, 38 % (OR 2.9, CI 1.8-4.9, P = 0.001) and 39 % (OR 3.4, CI 2.7-4.2, P = 0.001), respectively. Phosphorus levels within the upper normal limits (4-4.5 mg/dl) were associated with higher mortality rates compared to levels between 1.5-3.5 mg/dl, the reference group, 24 % (OR 1.9, CI 1.5-2.4, P = 0.001). CONCLUSIONS: Abnormal phosphorus levels on admission are associated with increased mortality rates among patients hospitalized with Community acquired pneumonia.

[SYNCOPE CAUSED BY INTRA-OCULAR TIMOLOL].

INTRODUCTION: Timolol eye-drops are commonly used for the treatment of glaucoma. Despite being topically applied, some systemic absorption occurs with the resulting adverse reactions related to its beta-adrenoreceptor blocking activity CASE PRESENTATION: We report the case of a 68 years old healthy male who was admitted to our department for further workup following two episodes of syncope. Medical history taking revealed that the episodes of syncope occurred soon after beginning treatment with intra-ocular timolol for glaucoma. An electrocardiogram demonstrated a sinus bradycardia rhythm and a prolonged PR interval, consistent with the negative effects of a beta adrenergic receptor antagonist on the heart's electrical generation and conduction system. DISCUSSION: This case demonstrates the potential for dangerous systemic side effects of a topically-applied medication. It also highlights the importance of thorough medical history taking in the evaluation of syncope, including inquiry regarding the use of all, especially new, medications. CONCLUSION: Detailed medical history taking can help in avoiding the performance of an expensive and unnecessary workup.

Is elevated red cell distribution width a prognostic predictor in adult patients with community acquired pneumonia?

BACKGROUND: Community acquired pneumonia (CAP) is a major cause of morbidity and mortality. We recently demonstrated that among young patients (<60 years old) with CAP, elevated red blood cell distribution width (RDW) level on admission was associated with significant higher rates of mortality and severe morbidity. We aimed to investigate the prognostic predictive value of RDW among CAP patients in general population of internal wards. METHODS: The cohort included patients of 18 years old or older who were diagnosed with CAP (defined as pneumonia identified 48 hours or less from hospitalization) between January 1, 2005 and December 31, 2010. Patients were retrospectively analyzed for risk factors for a primary endpoint of 90-day mortality. Secondary endpoint was defined as complicated hospitalization (defined as at least one of the following: In- hospital mortality, length of stay of at least 10 days or ICU admission). Binary logistic regression analysis was used for the calculation of the odds ratios (OR) and p values in univariate and multivariate analysis to identify association between patient characteristic, 90-day mortality and complicated hospitalization. RESULTS: The cohort included 3815 patients. In univariate analysis, patients with co-morbid conditions tended to have a complicated course of CAP. In multivariate regression analysis, variables associated with an increased risk of 90-day mortality included age > 70 years, high Charlson comorbidity index (>2), Hb < 10 mg/dl, Na <130 meq/l, blood urea nitrogen (BUN) >30 mg/dl, systolic blood pressure < 90 mmHg and elevated RDW >15%. Variables associated with complicated hospitalization included high Charlson comorbidity index, BUN > 30 mg/dl, hemoglobin < 10 g/dl, heart rate >124 bpm, systolic blood pressure < 90 mmHg and elevated RDW. Mortality rate and complicated hospitalization were significantly higher among patients with increased RDW regardless of the white blood cell count or hemoglobin levels. CONCLUSIONS: Elevated RDW levels on admission are associated with significant higher rates of mortality and severe morbidity in adult patients with CAP. RDW as a prognostic marker was unrelated with hemoglobin levels, WBC count, age or Charlson score.

Procalcitonin and interleukin 6 for predicting blood culture positivity in sepsis.

BACKGROUND: Procalcitonin and interleukin 6 (IL-6) are well-known predictors of blood culture positivity in patients with sepsis. However, the association of procalcitonin and IL-6 with blood culture positivity was assessed separately in previous studies. This study aims to examine and compare the performance of procalcitonin and IL-6, measured concomitantly, in predicting blood culture positivity in patients with sepsis. METHODS: Forty adult patients with sepsis were enrolled in the study. Blood cultures were drawn before the institution of antibiotic therapy. The area under the curve (AUC) of the receiver operating characteristic curve was estimated to assess the performance of procalcitonin and IL-6 in predicting blood culture positivity. RESULTS: Positive blood cultures were detected in 10 patients (25%). The AUC of procalcitonin and IL-6 was 0.85 and 0.61, respectively. The combined performance of procalcitonin and IL-6 was similar to that of procalcitonin alone, AUC of 0.85. On univariate analysis, only procalcitonin and IL-6 were associated with blood culture positivity. Multivariate logistic regression analysis showed that only procalcitonin was associated with blood culture positivity (odds ratio, 12.15 [1.29-114.0] for levels above the median compared with levels below the median). Using procalcitonin cut points of 1.35 and 2.14 (nanogram per milliliter) enabled 100% and 90% identification of positive blood cultures and reduced the need of blood cultures by 47.5% and 57.5%, respectively. CONCLUSIONS: Compared with IL-6, procalcitonin better predicts blood culture positivity in patients with sepsis. Using a predefined procalcitonin cut points will predict most positive blood cultures and reduce the need of blood cultures in almost half of patients with sepsis.

Brain natriuretic peptide at discharge as a predictor of 6-month mortality in acute decompensated heart failure.

BACKGROUND: Brain natriuretic peptide (BNP) is well established in detecting acute decompensation of heart failure (ADHF). The role of BNP at discharge in predicting mortality is less established. Accumulating evidence suggests that inflammatory cytokines play an important role in the development of heart failure. We aimed to examine the contribution of BNP, interleukin 6, and procalcitonin to mortality in ADHF. METHODS: A cohort of 33 patients with ADHF was identified between March 2009 and June 2010 at Rambam Health Care Campus, Haifa, Israel. The cohort was followed up for all-cause mortality during 6 months after hospital discharge. Cox proportional hazard model was used to assess the association between BNP, interleukin-6 and procalcitonin and all-cause mortality. RESULTS: As compared to BNP at admission, BNP at discharge was more predictive for all-cause mortality. The area under the curve for BNP at admission and discharge was 0.810 (P=.004) and 0.864 (P=.001) respectively. Eleven patients (33.3%) patients who died during the follow-up period had higher BNP levels, median 2031.4 (IQR, 1173.4-2707.2), than those who survived; median 692.5 (IQR, 309.9-1159.9), (P = .001). On multivariate analysis, BNP remained an independent predictor for 6 month all-cause mortality HR 9.58 (95% CI, 2.0-45.89) for levels above the median compared to lower levels, (P=.005). Albumin, procalcitonin and interleukin 6 were not associated with all-cause mortality. CONCLUSIONS: BNP at discharge is an independent predictor for all-cause mortality in patients with ADHF. Compared with BNP at admission, BNP at discharge has slightly higher predictive accuracy with regard to 6-month all-cause mortality.

Drug Survival on First Biologic Therapy Among Late-Onset Rheumatoid Arthritis Patients Compared to Early-Onset Patients: A Population-Based Cohort Study.

INTRODUCTION: Rheumatoid arthritis (RA) patients can be divided according to the age of disease onset and classified as late-onset RA ≥ 60 years old or early-onset RA < 60 years old. Current treatment guidelines do not stipulate any preference regarding the biologic that should be used first in the late-onset group. This study aims to compare the drug survival times on first biological treatment between late and early-onset RA patients. METHODS: This is a population based cohort study using the medical records of Leumit healthcare services. We included all eligible RA patients between 2000 and 2017. RA patients were divided into late- and early-onset RA groups and compared according to drug survival time on the first biological therapy. RESULTS: The final cohort included 3814 RA patients, 2807 (73.6%) of whom had early-onset RA. Overall, biologic disease-modifying anti-rheumatic drugs (bDMARDs) were used more often among early-onset compared to late-onset patients (16.9% vs. 7.8%, p < 0.001). Among early-onset patients, etanercept was associated with the longest drug survival time on the first biologic, and adalimumab and infliximab were associated with the longest drug survival times among late-onset patients. No differences were observed in drug survival times between late and early-onset patients on the first bDMARD, except for abatacept and golimumab with longer drug survival time among early-onset patients. CONCLUSION: Late-onset RA patients were treated with biologics to a lesser extent than early-onset patients, but no differences were observed in drug survival times at the first bDMARD between the two groups.

Acute obstructive jaundice and chronic cirrhosis protect against the adverse renal effects of pneumoperitoneum: role of nitric oxide.

BACKGROUND: Obstructive jaundice and cirrhosis are associated with impaired renal function. Previously we demonstrated that increased intra-abdominal pressure (IAP, pneumoperitoneum) in normal rats induced renal dysfunction. This study investigated the renal effects of pneumoperitoneum in rats with acute jaundice and cirrhotic rats. METHODS: Following a baseline period, rats with obstructive jaundice or cirrhosis induced by acute or chronic bile duct ligation (BDL), respectively, and their sham-controls were subjected to consecutive IAPs of 10 and 14 mmHg for 45 min each. Urine flow (V), Na(+) excretion (UNaV), glomerular filtration rate (GFR), renal plasma flow (RPF), and urinary NO metabolites ([Formula: see text]) and cGMP (UcGMP) were determined. RESULTS: Elevating IAP from 0 to 10 and 14 mmHg in normal rats caused IAP-dependent reductions in V, UNaV, GFR, RPF, [Formula: see text] and UcGMP. Basal renal function and hemodynamics were lower in rats with obstructive jaundice. In contrast to normal rats, application of elevated IAP of 10 and 14 mmHg significantly improved V, UNaV, GFR, RPF, and MAP along with increased [Formula: see text] and preserved UcGMP. Similarly, when identical IAP conditions were applied to cirrhotic rats, no deleterious changes in V, UNaV, GFR or RPF were observed. CONCLUSIONS: Application of pneumoperitoneum to rats with acute BDL improves kidney function and renal hemodynamics. Likewise, increased IAP does not exert adverse renal effects in cirrhotic rats. These effects are distinct from the deleterious renal consequences of increased IAP in normal rats. Perturbations in the generation of NO/cGMP during IAP in normal rats but not in rats with BDL or cirrhosis may contribute to these differences.

Interleukin-6 at discharge predicts all-cause mortality in patients with sepsis.

PURPOSE: Interleukin-6 (IL-6) is a proinflammatory cytokine that plays a central role in the pathogenesis of sepsis. We aim to investigate the association between IL-6 and all-cause mortality in patients with sepsis. METHODS: A cohort of 40 elderly patients with sepsis was identified between March 2009 and June 2010 at Rambam Health Medical Campus, Haifa, Israel. The cohort was followed up for all-cause mortality occurring during the 6 months after hospital discharge. Cox proportional hazard model was used to assess the association between IL-6 and all-cause mortality. RESULTS: Iinterleukin-6 at discharge had a higher predictive accuracy for all-cause mortality when compared with IL-6 at admission. The area under the curve was 0.752 (P = .015) and 0.545 (P = .661), respectively. Eleven (27.5%) patients died during follow-up; the subjects who died have higher IL-6 levels at discharge (median, 50.6 pg/mL [interquartile range, 39.6-105.9]) compared with survivors at the end of follow-up (median, 35.4 [interquartile range, 15.8-49]; P = .014). The risk of all-cause mortality was higher in subjects with IL-6 levels above the median compared with subjects with lower IL-6 levels (log-rank P = .017). On multivariate Cox proportional analysis, adjusting for the potential confounders, IL-6 at discharge remained an independent predictor for 6 month all-cause mortality (hazard ratio, 6.05 [1.24-24.20]) for levels above the median compared with lower levels. CONCLUSIONS: Iinterleukin-6 at discharge is an independent predictor of all-cause mortality in patients with sepsis. Compared with IL-6 at admission, IL-6 at discharge better predicts all-cause mortality.

Normotensive scleroderma renal crisis as the presenting symptom of systemic sclerosis sine scleroderma: A case report.

Scleroderma renal crisis is a rare but serious complication of systemic sclerosis. It is usually associated with marked hypertension and carries significant risk for morbidity and mortality. Its occurrence prior to the development of skin sclerosis is exceedingly rare. We report a case of a patient who presented with recurrent pericardial effusion and later tested positive for anti-nuclear and anti-topoisomerase antibodies. He later developed normotensive renal crisis as confirmed by kidney biopsy despite complete absence of skin involvement. To our knowledge, this is the first published case of a patient presenting with normotensive renal crisis without any skin involvement.

Challenges in the Timely Diagnosis of Behcet's Disease.

Behcet's disease (BD) is a chronic, multi-systemic inflammatory disorder mainly characterized by recurrent oral and genital ulcers, skin lesions, and uveitis. As no pathognomonic laboratory test exists for BD, the diagnosis relies solely on clinical features. Over the years, great efforts have been invested in creating clinical diagnostic and classification criteria. The international study group criteria introduced in 1990 were the first true multinational set of criteria. Despite improving the ability to diagnose BD, these criteria still have limitations, including the inability to diagnose patients presenting without oral ulcers or presenting with rare manifestations of the disease. This led to the introduction of the international criteria for BD in 2013, which improved the sensitivity with minimal compromise on specificity. Despite the efforts made and as our understanding of the clinical manifestations of BD and genetic pathogenesis continue to evolve, efforts should be made to further enhance the currently accepted international classification criteria, perhaps by incorporating genetic testing (e.g., family history or HLA typing) as well as ethnic group-specific features.

A very rare cause of blue finger: A case-based review.

Introduction: Cryofibrinogen is an abnormal, cold-insoluble protein composed of a combination of fibrinogen, fibrin, and fibronectin. Cryofibrinogenemia can be essential (e.g. primary) or secondary to various conditions. While low levels of cryofibrinogen can be seen in asymptomatic healthy individuals without evidence of clinical features typical of cryofibrinogenemia, cryofibrinogenemia associated with clinical features is considered very rare. The clinical features of cryofibrinogenemia ranges from skin manifestations, including Raynaud's phenomenon and livedo reticularis, to more severe organ-threatening manifestations such as tissue ischemia and gangrene. Case description: We report a case of a 48-year-old male who presented with blue finger and palpable purpura on his distal extremities. Laboratory workup was positive for anti-nuclear antibodies, anti-double-stranded DNA, anti-ribonucleoprotein, and rheumatoid factor, while antineutrophil cytoplasmic antibodies and cryoglobulins were negative. Testing for hypercoagulable states and infectious etiologies was unrevealing. Later, angiographic computed tomography showed multiple pulmonary embolisms and disruption of blood flow to the left fifth digit. As the aforementioned workup could not explain the presence of the thrombus by a thromboembolic cause, a search for an in situ cause other than antiphospholipid syndrome was initiated and concentrated mainly on cryofibrinogenemia. Blood samples collected using prewarmed anticoagulant containing tubes were sent to central lab familiar with performing the test. Two weeks later, a positive result for the presence of cryofibrinogen confirmed the diagnosis of cryofibrinogenemia. Due to the presence of multiple signs compatible with mixed connective tissue disease, he was diagnosed with cryofibrinogenemia secondary to mixed connective tissue disease, and treatment with prednisone, low-molecular-weight heparin, prostacyclin and hydroxychloroquine was initiaed with favorable outcome. Conclusion: Cryofibrinogenemia is a rare and underdiagnosed condition. Clinicians should be aware of this cryopathy especially in the cases of Raynaud's phenomenon and ischemic ulcers not explained by other causes. Precautions must be taken during the diagnostic process, and therapy should be given as soon as possible.

Biologic therapy is associated with malignancies among Israeli patients with rheumatoid arthritis: A population-based study.

AIMS: To examine whether biologic disease-modifying anti-rheumatic drugs (bDMARDs) are associated with increased risk of malignancy among Israeli patients with rheumatoid arthritis (RA). METHODS: We identified RA patients meeting specified inclusion and exclusion criteria from the Leumit healthcare services database between the years 2000 and 2017. Data were collected regarding bDMARD and conventional DMARD consumption, types of malignancies, and their temporal relation to RA diagnosis. The association between baseline variables and occurrence of malignancies was examined by Cox regression. RESULTS: Among 4268 eligible RA patients, 688 (16.12%) were diagnosed with any malignancy. Melanoma skin cancer (MSC) was the most prevalent malignancy (148/688, 21.5%). The proportions out of all malignancies of MSC and non-melanoma skin cancer (NMSC) were higher after than before RA diagnosis (24.7% vs 19.1%, p = .025 and 24.7% vs 13.0%, p = .021, respectively). A higher proportion of RA patients diagnosed with malignancy used bDMARDs in comparison with RA patients who were malignancy-free (40.2% vs 17.5%, p < .001). After adjusting for demographic and clinical variables, bDMARDs were associated with an increased risk of malignancy (hazard ratio 1.42, 95% confidence interval 1.10-1.78). CONCLUSIONS: Biologic DMARDs are associated with increased risk of malignancy among Israeli RA patients, presumably contributed by MSC and NMSC. MSC was the most prevalent type of malignancy in this cohort and may indicate a predisposition state among Israeli RA patients.

Neurosarcoidosis: The Presentation, Diagnosis and Treatment Review of Two Cases.

Sarcoidosis is a chronic granulomatous disease of unknown cause characterized by the presence of non-caseating granulomas. The disease can affect any organ including the nervous system. Neurosarcoidosis occurs in about 5% patients with sarcoidosis. The clinical presentation of neurosarcoidosis is varied, and it can involve the brain, spinal cord and peripheral nervous system, separately or in different combinations. The diagnosis of neurosarcoidosis is challenging, as biopsies from the nervous system are not readily available. Anti-TNFα agents are becoming one of the cornerstone treatments for neurosarcoidosis. In this case-based review, we discuss two cases of neurosarcoidosis with different clinical presentations. The first patient presented with confusion, while the second presented with walking difficulty and neurogenic bladder. Both patients were treated with methylprednisolone pulse therapy with rapid, but non-complete, improvement. Therefore, infliximab was initiated in both cases with subsequent improvement in the clinical manifestations and imaging findings, emphasizing the effectiveness and safety of infliximab in cases of severe neurosarcoidosis. In conclusion, the goal of neurosarcoidosis management is to prevent organ system damage and minimize the toxic cumulative adverse effects of glucocorticoid use. In this case-based review we discuss the various presentations, the diagnosis and the treatment of neurosarcoidosis.

Cognitive Impairment in Anti-Phospholipid Syndrome and Anti-Phospholipid Antibody Carriers.

Cognitive impairment is frequently reported among anti-phospholipid syndrome (APS) patients as well as anti-phospholipid antibody (aPL) carriers, but it is less studied than other manifestations of this condition. Moreover, the exact prevalence of cognitive impairment in these patients has not been accurately determined, mainly due to inconsistency in the tools used to identify impairment, small sample sizes, and variability in the anti-phospholipid antibodies measured and positivity cutoffs. The notion of a direct pathogenic effect is supported by the observation that the higher the number of aPLs present and the higher the load of the specific antibody, the greater the risk of cognitive impairment. There is some evidence to suggest that besides the thrombotic process, inflammation-related pathways play a role in the pathogenesis of cognitive impairment in APS. The cornerstone treatments of APS are anti-coagulant and anti-thrombotic medications. These treatments have shown some favorable effects in reversing cognitive impairment, but solid evidence for the efficacy and safety of these treatments in the context of cognitive impairment is still lacking. In this article, we review the current knowledge regarding the epidemiology, pathophysiology, clinical associations, and treatment of cognitive impairment associated with APS and aPL positivity.
