Ophthalmologic profile of patients with systemic sclerosis.

PURPOSE: To study the ophthalmologic manifestations of systemic sclerosis (SSc) and its correlation with autoantibody profile. METHODS: A cross-sectional study on 200 eyes of 100 consecutive adult patients diagnosed with SSc was performed at a tertiary care center in Northern India. The examination of ocular adnexa, anterior segment, and posterior segment with slit-lamp biomicroscopy, tear film break-up time (TBUT), Schirmer's II test, and choroidal thickness measurement by swept-source ocular coherence tomography was done. Autoantibody profile was available for 85 patients, and its statistical association with the ocular examination findings was analyzed. RESULTS: In total, 100 patients (93 females and 7 males) were included. The mean age was 45.11 ± 11.68 years, and the mean disease duration was 6.93 ± 3.68 years. Meibomian gland disease was more commonly found in patients with the diffuse subtype of SSc (P = 0.037). Choroidal thickness was increased in 34% and decreased in 7% (reference range = 307 ± 79 mm) patients. Reduced TBUT, meibomian gland dysfunction, and eyelid stiffness had a statistically significant association with the presence of anti-Scl-70 antibody (P = 0.003, <0.0001, and 0.004, respectively). These patients had ocular fatigue, foreign body sensation, and burning sensation. No significant association was noted with the presence of SS-A/Ro and SS-B/La antibodies. CONCLUSION: This study highlights the need for an active comprehensive ophthalmic evaluation. Approximately 75% of the patients in our cohort had ocular involvement to varying extent. An isolated presence of anti-Scl70 antibody was also found to have a positive association with dry eye disease.

Long-term efficacy and safety of subcutaneous pasireotide alone or in combination with cabergoline in Cushing's disease.

Objective: This study evaluated short- and long-term efficacy and safety of the second-generation somatostatin receptor ligand pasireotide alone or in combination with dopamine agonist cabergoline in patients with Cushing's disease (CD). Study design: This is an open-label, multicenter, non-comparative, Phase II study comprising 35-week core phase and an optional extension phase. All patients started with pasireotide, and cabergoline was added if cortisol remained elevated. Eligible patients had active CD, with or without prior surgery, were pasireotide naïve at screening or had discontinued pasireotide for reasons other than safety. Primary endpoint was proportion of patients with a mean urinary free cortisol (mUFC) level not exceeding the upper limit of normal (ULN) at week 35 with missing data imputed using last available post-baseline assessments. Results: Of 68 patients enrolled, 26 (38.2%) received pasireotide monotherapy and 42 (61.8%) received pasireotide plus cabergoline during the core phase. Thirty-four patients (50.0%; 95% CI 37.6-62.4) achieved the primary endpoint, of whom 17 (50.0%) received pasireotide monotherapy and 17 (50.0%) received combination therapy. Proportion of patients with mUFC control remained stable during the extension phase up to week 99. Treatment with either mono or combination therapy provided sustained improvements in clinical symptoms of hypercortisolism up to week 99. Hyperglycemia and nausea (51.5% each), diarrhea (44.1%) and cholelithiasis (33.8%) were the most frequent adverse events. Conclusion: Addition of cabergoline in patients with persistently elevated mUFC on maximum tolerated doses of pasireotide is an effective and well-tolerated long-term strategy for enhancing control of hypercortisolism in some CD patients.

The machine learning and geostatistical approach for assessment of arsenic contamination levels using physicochemical properties of water.

Arsenic contamination in groundwater due to natural or anthropogenic sources is responsible for carcinogenic and non-carcinogenic risks to humans and the ecosystem. The physicochemical properties of groundwater in the study area were determined in the laboratory using the samples collected across the Varanasi region of Uttar Pradesh, India. This paper analyses the physicochemical properties of water using machine learning, descriptive statistics, geostatistical and spatial analysis. Pearson correlation was used for feature selection and highly correlated features were selected for model creation. Hydrochemical facies of the study area were analyzed and the hyperparameters of machine learning models, i.e., multilayer perceptron, random forest (RF), naïve Bayes, and decision tree were optimized before training and testing the groundwater samples as high (1) or low (0) arsenic contamination levels based on the WHO 10 µg/L guideline value. The overall performance of the models was compared based on accuracy, sensitivity, and specificity value. Among all models, the RF algorithm outclasses other classifiers, as it has a high accuracy of 92.30%, a sensitivity of 100%, and a specificity of 75%. The accuracy result was compared to prior research, and the machine learning model may be used to continually monitor the amount of arsenic pollution in groundwater.

Comparison between methotrexate and apremilast in Psoriatic Arthritis-a single blind randomized controlled trial (APREMEPsA study).

To compare the efficacy of methotrexate and apremilast in psoriatic arthritis (PsA). This Single blinded (physician), parallel group, randomized controlled trial was conducted at a single centre between October 2019 and December 2020. Adult PsA patients (age > 18 years), fulfilling CASPAR criteria, not on methotrexate/apremilast in last 3 months and never receiving bDMARDs or, JAK inhibitors, having active articular disease (one or more swollen joint or, having one or more tender entheseal point) were recruited. Primary outcome measure was rate of major cDAPSA response at week 24 and secondary outcome measures were ACR 20 response, change in PASI score, Maastricht enthesitis score, Leeds dactylitis index, and health assessment questionnaire-disability index (HAQ-DI) and number of adverse events at week 24 between methotrexate and apremilast groups. A total of 31 patients were recruited (15 in the apremilast arm and 16 in the methotrexate arm) amongst whom 26 patients completed 24 weeks follow up (13 patients in the apremilast arm and 13 patients in the methotrexate arm). Median cDAPSA score at baseline was 23 (9) in the apremilast group and 20 (21) in the methotrexate group. No difference in major cDAPSA response at week 24 was observed between apremilast and methotrexate arm (20% vs. 37.5%; p = 0.433). In the secondary outcome measures, there was no significant differences between both the groups. Both the drugs were safe without any serious adverse events. There was no significant difference between methotrexate and apremilast in terms of efficacy as measured by cDAPSA and ACR20 responses.

Does post-COVID reactive arthritis exist? Experience of a tertiary care centre with a review of the literature.

BACKGROUND: Rheumatological manifestations following COVID-19 are various, including Reactive Arthritis (ReA), which is a form of asymmetric oligoarthritis mainly involving the lower limbs, with or without extra-articular features. The current case series describes the clinical profile and treatment outcome of 23 patients with post-COVID-19 ReA. METHODS: A retrospective, observational study of patients with post-COVID-19 arthritis over one year was conducted at a tertiary care centre in India. Patients (n=23) with either a positive polymerase chain reaction test for SARS-CoV2 or an anti-COVID-19 antibody test were included. Available demographic details, musculoskeletal symptoms, inflammatory markers, and treatment given were documented. RESULTS: Sixteen out of 23 patients were female. The mean age of the patients was 42.8 years. Nineteen patients had had symptomatic COVID-19 infection in the past. The duration between onset of COVID-19 symptoms and arthritis ranged from 5 to 52 days with a mean of 25.9 days. The knee was the most involved joint (16 out of 23 cases). Seven patients had inflammatory lower back pain and nine had enthesitis. Most patients were treated with non-steroidal anti-inflammatory drugs (NSAIDs) and steroids - either depot injection or a short oral course. Three patients required treatment with hydroxychloroquine and methotrexate which were eventually stopped. No relapse was reported in any of the patients. CONCLUSION: On combining our data with 21 other case reports of ReA, a lower limb predominant, oligoarticular, asymmetric pattern of arthritis was seen with a female preponderance. The mean number of joints involved was 2.8. Axial symptoms and enthesitis were often coexistent. Treatment with NSAIDs and intra-articular steroids was effective. However, whether COVID-19 was the definitive aetiology of the arthritis is yet to be proven.

Prevalence and pattern of myocardial involvement on cardiac magnetic resonance imaging in Takayasu arteritis and its relationship with disease activity.

BACKGROUND: Cardiac involvement in Takayasu arteritis (TA) is the major cause of morbidity and mortality. Cardiovascular magnetic resonance (CMR) is an excellent modality for the assessment of myocardial involvement. Studies have shown myocardial involvement in 25%-27% of patients. OBJECTIVES: To evaluate the prevalence and pattern of myocardial involvement in TA on CMR. We also evaluated any correlation between CMR changes and disease activity score (ITAS 2010 and ITAS-A) assessed at the time of CMR. METHODS: Patients classified as Takayasu arteritis according to Sharma et al. criteria were enrolled in the study. Demographic, clinical, and laboratory data were documented in the predesigned proforma. CMR was performed on a dedicated cardiac 3Tesla MR machine. Disease activity was recorded by ITAS2010 and ITAS-A. RESULTS: A total of 37 TA patients were included. Mean (±SD) age was 29±11 years. Female to male ratio was 3:1. Five patients (14%) had myocardial involvement on CMR. Two (2/5) had myocarditis and three (3/5) patients had features of ischaemic myocardial fibrosis. CONCLUSION: The myocardium is affected in TA, however the prevalence of subclinical myocardial involvement in our study was less (8% vs. 25%-27%) compared to the previous studies. Myocardial involvement trends towards early age of onset, less disease duration, lack of classical risk factors, and more with disease activity.

Antecedentes: La afectación cardíaca en la arteritis de Takayasu (AT) es la principal causa de morbmortalidad. La resonancia magnética cardiovascular (RMC) es una modalidad excelente para la evaluación de la afectación miocárdica. Los estudios han demostrado afectación del miocardio en el 25-27% de los pacientes. Objetivos: Evaluar la prevalencia y patrón de afectación miocárdica en AT en RMC. También se evaluó cualquier correlación entre los cambios de RMC y la puntuación de actividad de la enfermedad (ITAS 2010 e ITAS-A) evaluada en el momento de la RMC. Métodos: Pacientes clasificados como arteritis de Takayasu según los criterios de Sharma et al. se inscribieron en el estudio. Los datos demográficos, clínicos y de laboratorio se documentaron en el formulario prediseñado. La RMC se realizó en una máquina de RM cardíaca de 3 Tesla dedicada. La actividad de la enfermedad fue registrada por ITAS 2010 e ITAS-A. Resultados: Se incluyeron un total de 37 pacientes con AT. La edad media (±DE) fue de 29±11 años. La proporción de mujeres a hombres fue de 3:1. Cinco pacientes (14%) tenían afectación miocárdica en la RMC. Dos (2/5) tenían miocarditis y 3 (3/5) pacientes tenían características de fibrosis miocárdica isquémica. Conclusión: El miocardio es afectado en la AT, sin embargo, la prevalencia de afectación miocárdica subclínica en nuestro estudio fue menor (8% vs. 25-27%) en comparación con los estudios previos. La afectación miocárdica tiende hacia una edad de inicio temprana, menor duración de la enfermedad, falta de factores de riesgo clásicos y más con la actividad de la enfermedad.(AU)

Clinical presentation and treatment outcomes of arterial involvement in Behçet's disease: a single-centre experience.

Arterial involvement, although rare, accounts for significant mortality and morbidity in patients of Behçet's disease (BD). There is paucity of data on arterial BD. The objective of this 5-year retrospective cohort study was to examine the clinical presentation, pattern of arterial involvement, and treatment outcome in Indian arterial BD patients. Data on demography, clinical presentation, radiology, instituted therapy, vascular interventions and treatment outcomes were recorded and analyzed. Ten (16.9%) out of 59 patients with BD had arterial involvement in 13 vascular territories [mean age 30 (8) years, 9 (90%) males]. Pulmonary artery was most commonly involved (46%), followed by abdominal aorta (15%), femoral artery (15%), descending thoracic aorta (8%), common iliac (8%), and dorsalis pedis artery (8%). Two patients had multi-territory involvement. The median interval between disease onset and development of arterial aneurysms was 3 years (3 months-12 years). Concomitant deep vein thrombosis was seen in 60% cases. Prednisolone and cyclophosphamide were the most common immunosuppressive therapy used; one patient who relapsed on cyclophosphamide responded to infliximab. Five surgical or endovascular interventions were performed. Four patients (40%) died due to aneurysm rupture-all had a delayed diagnosis, and three had pulmonary artery involvement, with death due to massive hemoptysis. Based on the present study, we concluded that arterial involvement in BD is seen predominantly in males and has a high mortality. Early detection and aggressive treatment with immunosuppression and surgical or endovascular interventions are essential for good outcomes.
