Effect of oculomotor exercises in patients with non-specific chronic neck pain and associated visual complaints.

Background: Neck pain is a common musculoskeletal disorder, the most common type being non-specific chronic neck pain. It usually involves postural or mechanical causes. In Individuals with neck pain, a notable prevalence of visual complaints has been predominantly reported. It can be linked to the mismatch in the cervical afferent output. Objective: This study aimed to assess the effect of oculomotor exercises on neck pain, neck disability, gaze stability and visual complaints among individuals with non-specific chronic neck pain and associated visual complaints. Methods: A total of 32 individuals with non-specific chronic neck pain and associated visual complaints were equally randomised into two groups. To receive either: stretching to the sternocleidomastoid and anterior scalene along with neck Isometric exercises (Group A, conventional) or the conventional protocol along with oculomotor exercises (Group B, experimental). The protocol was given for three alternate days a week for three weeks, a total of nine sessions. The outcome measures were the Visual Analogue Scale (VAS) for pain, Neck Disability Index (NDI) for disability, Dynamic Visual Acuity (DVA) test for gaze stability and Visual Complaints Index (VCI) for visual complaints. Results: Significant results were seen for the DVA (p=0.002) and VCI (p=0.024), suggesting improvements in gaze stability and visual complaints using oculomotor exercises. Conclusion: From this study, we highlighted that oculomotor exercises along with conventional treatment led to improvement in visual complaints and gaze stability in patients with non-specific chronic neck pain and associated visual complaints.

Caregiver burden in families of children with juvenile idiopathic arthritis in India.

Juvenile Idiopathic Arthritis (JIA) causes caregiver burden on families with children affected with it. Our study aimed to explore this multifaceted burden in the Indian context. In this cross-sectional study, we administered the Hindi translated CAREGIVER questionnaire to adult caregivers in the families of JIA patients ≤ 18 years. The responses to the 28 items were used to calculate the burden scores in various dimensions. The relationship of the global burden scores with demographic and socioeconomic factors were analysed. Non parametric tests were used. Two hundred twenty-one caregivers participated with a median age of 39 years (IQR 32-45). This included 116 fathers, 50 mothers, 32 brothers, 18 uncles, three grandfathers, one sister, and one grandmother. The JIA patients had a median age of 15 (12-17) years, and the male-to-female ratio was 3.2:1. Enthesitis-related arthritis was the predominant subtype (72.4%). Most caregivers (70.6%) expressed sadness at diagnosis, and 29.9% continued to express sadness. Nearly two-thirds (65.6%) had to borrow money from others. More than half (59.3%) of the caregivers neglected their health, and 9.0% became sick. Male gender of the child, systemic JIA subtype, low socioeconomic status, high disease activity, extra-articular damage, high parent-reported disease activity and poor quality of life were associated with higher global caregiver burden. JIA has a significant emotional, social, economic, and labour impact on caregivers. Economic and psychosocial support needs to be given to family caregivers caring for children with JIA.

Effectiveness of instrument assisted soft tissue mobilization versus foam rolling on trigger point release in calf muscles.

BACKGROUND: Instrument assisted soft tissue mobilization and foam rolling are two techniques that have been proven effective in treating Myofascial Trigger Points, irrespective of the type of trigger point. However, little is known about the comparative effectiveness of Instrument assisted soft tissue mobilization and foam rolling. This study proposed to evaluate the effectiveness of either technique on plantar flexors trigger points, ankle dorsiflexion, and lower limb power present in the calf muscles in non-symptomatic patients. METHOD: Forty-two subjects with bilateral calf muscle tightness, at least one trigger point in the calf muscle, and fulfilling the inclusion criteria were randomly assigned to either of the groups. Group A was treated for gastrocnemius and soleus trigger points using Instrument assisted soft tissue mobilization and Group B was treated using the Foam Rolling method. Treatment was given every alternate day, a total of 3 sessions. Subjects were evaluated on 1st and 3rd sessions for pre-post differences of ankle dorsiflexion Range of motion in weight bearing and non-weight bearing position, pressure pain threshold for gastrocnemius trigger point 1(G1), 2(G2), and soleus point 1(S1) on both sides, and lower limb power. RESULT: Within group analyses, both groups had shown statistically significant results for all parameters except gastrocnemius trigger point 2 of foam rolling. For between group comparison foam rolling had a statistically significant result in non-weight bearing ankle dorsiflexion range of motion. CONCLUSION: Both Instrument assisted soft tissue mobilization and Foam rolling were equally effective for treating calf trigger points. But foam rolling was more effective in improving ankle dorsiflexion range of motion.

Treatment of non-systemic juvenile idiopathic arthritis.

In the past two decades, the treatment of juvenile idiopathic arthritis (JIA) has evolved markedly, owing to the availability of a growing number of novel, potent and relatively safe therapeutic agents and the shift of management strategies towards early achievement of disease remission. However, JIA encompasses a heterogeneous group of diseases that require distinct treatment approaches. Furthermore, some old drugs, such as methotrexate, sulfasalazine and intraarticular glucocorticoids, still maintain an important therapeutic role. In the past 5 years, information on the efficacy and safety of drug therapies for JIA has been further enriched through the accomplishment of several randomized controlled trials of newer biologic and synthetic targeted DMARDs. In addition, a more rational therapeutic approach has been fostered by the promulgation of therapeutic recommendations and guidelines. A multinational collaborative effort has led to the development of the recommendations for the treat-to-target strategy in JIA. There is currently increasing interest in establishing the optimal time and modality for discontinuation of treatment in children with JIA who achieve sustained clinical remission. The aim of this Review is to summarize the current evidence and discuss the therapeutic approaches to the management of non-systemic phenotypes of JIA, including oligoarthritis, polyarthritis, enthesitis-related arthritis and psoriatic arthritis.

OMERACT 2023 Systemic Lupus Erythematosus Special Interest Group: Winnowing and Binning Preliminary Candidate Domains for the Core Outcome Set.

BACKGROUND: The Outcome Measures in Rheumatology (OMERACT) Systemic Lupus Erythematosus (SLE) Working Group held a Special Interest Group (SIG) at the OMERACT 2023 conference in Colorado Springs where SLE collaborators reviewed domain sub-themes generated through qualitative research and literature review. OBJECTIVE: The objective of the SIG and the subsequent meetings of the SLE Working Group was to begin the winnowing and binning of candidate domain sub-themes into a preliminary list of candidate domains that will proceed to the consensus Delphi exercise for the SLE COS. METHODS: Four breakout groups at the SLE SIG in Colorado Springs winnowed and binned 132 domain sub-themes into candidate domains, which was continued with a series of virtual meetings by an advisory group of SLE patient research partners (PRPs), members of the OMERACT SLE Working Group Steering Committee, and other collaborators. RESULTS: The 132 domain sub-themes were reduced to a preliminary list of 20 candidate domains based on their clinical and research relevance for clinical trials and research studies. CONCLUSION: A meaningful and substantial winnowing and binning of candidate domains for the SLE COS was achieved resulting in a preliminary list of 20 candidate domains.

Gastrointestinal Manifestations in Systemic Lupus Erythematosus: Data from an Indian Multi-institutional Inception (INSPIRE) Cohort.

OBJECTIVES: To study the prevalence, correlates, and outcomes of GI manifestations in a prospectively enrolled nationwide cohort of SLE in India (INSPIRE). METHODS: It is an observational cohort study with analysis of the baseline database of the INSPIRE cohort with early outcomes assessed till April 10, 2023. Cases with GI manifestations as per the BILAG index were selected, pertinent clinical and laboratory data were retrieved for analysis. Patients with GI manifestations were compared with the rest of the cohort and factors associated with death were determined. RESULTS: Of the 2503 patients with SLE enrolled in the INSPIRE cohort, 243(9.7%) had GI manifestations observed early in the disease course(1,0-3 months). Ascites(162,6.5%), followed by enteritis(41,1.6%), pancreatitis(35,1.4%) and hepatitis(24,0.9%) were the most prevalent manifestations.All patients received immunosuppressive therapy, and four patients required surgery. Twenty-nine patients died(11.9%), with uncontrolled disease activity(17,58.6%) and infection(6,20.7%) accounting for the majority of deaths. Low socioeconomic class[lower(Hazard Ratio (95% Confidence intervals- CI) 2.8(1.1-7.9); upper lower 7.5(2-27.7); reference as upper class] and SLEDAI 2K[1.06(1.02-1.11)] were associated with death in the GI group.GI manifestations were significantly associated with age[Odds Ratio & 95% CI 0.97(0.96-0.99)], pleural effusion[4.9(3.6-6.7)], thrombocytopenia[1.7(1.2-2.4)], myositis[1.7(1.1-2.7)], albumin[0.7(0.5-0.8)], alkaline phosphatase(ALP)[1.01(1.0-1.002)], low C3[1.9(1.3-2.5)], total bilirubin[1.2(1.03-1.3)], alopecia[0.62(0.5-0.96], elevated anti-dsDNA[0.5(0.4-0.8)], and anti-U1RNP antibody[0.8(0.5-0.7)] in model one; and age[0.97(0.96-0.99)], creatinine[1.2(1.03-1.4)], total bilirubin[1.2(1.03-1.3)], ALP[1.01(1.0-1.002)], albumin[0.6(0.5-0.7)], andanti-U1RNP antibody[0.6(0.5-0.8)] in model two in multivariate analysis compared with patients without GI features. The mortality was higher in the GI group(11.9% and 6.6%, p= 0.01) as compared with controls. CONCLUSION: GI manifestations were observed in 9.7% of the cohort and were always associated with systemic disease activity and had higher mortality.

Pattern of disease expression in SLE patients with antiphospholipid antibodies: data from Indian Systemic Lupus Erythematosus Inception cohort (INSPIRE).

Antiphospholipid antibodies (APLA) are present in one-third of systemic lupus erythematosus (SLE) patients, and they are associated with both criteria and non-criteria manifestations. We studied the prevalence, clinical associations, and impact on mortality of APLA in SLE patients from India. Among the Indian SLE inception cohort (INSPIRE), patients who had data on all five routinely performed APLAs [lupus anticoagulant (LA), IgG and IgM anticardiolipin antibody (aCL) and anti-ß2-glycoprotein I(ß2GPI)] at enrolment were selected. Patients were divided into four categories based on the presence/absence of APLA associated manifestations and presence/absence of the APLA viz SLE-APS, SLE-APLA, SLE: events but no APLA, and SLE: no events, no APLA (reference group). 1035 SLE patients at least 1 APLA antibody was detected in 372 (35.9%). LA was present in 206 (19.9%), aCL in 126 (12.2%) and ß2-GPI in 178 (17.2%). There were 88 thrombotic events in 83 patients (8.0%); 73 (82.9%) being arterial; APLA positivity was present in 37 (44.6%) [AOR 1.70 (1.054, 2.76)]. SLE-APS patients were younger and had higher mortality [AOR 4.11 (1.51, 11.3)], neuropsychiatric and hematologic disease. SLE-APLA also had a higher mortality rate [AOR 2.94 (1.06, 8.22)] than the reference group. The mortality was highest in the subset of patients with thrombotic events in the presence of APLA [AOR 7.67 (1.25, 46.9)]. The mere presence of APLA also conferred higher mortality even in the absence of thrombotic events [AOR 3.51 (1.43, 8.63)]. Hematologic manifestations (36.1%) were the most common non-criteria-manifestation. One-third of SLE patients have APLA and its presence is associated with non-criteria hematologic manifestations, arterial thrombosis and higher mortality rate.

Systemic Lupus Erythematosus in Children.

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease, that mainly affects skin, joints and kidneys but can affect any organ in the body. It is characterized by presence of multiple autoantibodies like ANA, antibodies to dsDNA and RNA associated proteins. The major mechanism leading to tissue damage includes immune complex mediated complement activation, interferon alpha release by plasmacytoid dendritic cells, NETosis by neutrophils as well as defects in monocytes leading to poor clearance of cellular debris and direct cellular dysfunction mediated by antibodies. A child can present with pyrexia of unknown origin, immune mediated cytopenias, malar rash, oral ulcers, serositis, glomerulonephritis or nervous system dysfunction. As renal disease has a bearing on the long term impact, all children should have urine exam and blood pressure measurement done to rule out renal disease. The treatment varies depending on the severity and organs involved. In life or organ threatening situations, pulse methylprednisolone is used. Hydroxychloroquine, Mycophenolate mofetil, Azathioprine and Cyclophosphamide are the commonly used drugs in SLE. Over the years the prognosis of SLE has improved probably due to early diagnosis and better use of immunosuppressive treatment, regular follow up and treatment of co-morbidities. The 10-year survival now approaches 90% and with advent of new and targeted therapy it is hoped that the morbidity and organ damage can also be minimized.

Long-standing and poorly controlled disease in juvenile dermatomyositis is associated with calcinosis: a real-world experience from a low-middle income country.

To study the prevalence and predictors of calcinosis in Juvenile Dermatomyositis (JDM). Medical records over 20 years at a tertiary care rheumatology center in Northern India were reviewed to identify patients with JDM and clinical details were recorded. The frequency of calcinosis, predictors, specific treatment, and its outcomes were studied. Data are expressed as median and interquartile range. In eighty-six patients (median age 10) of JDM, the frequency of calcinosis was 18.2% (8.5% at presentation). Younger age at presentation, longer follow-up, heliotrope rash [Odds Ratio (95% confidence interval), 11.4 (1.4-92.12)], chronic or polycyclic course [4.4 (1.2-15.5)] and cyclophosphamide use [8.2 (1.6-41.9)] were associated with calcinosis. Dysphagia [0.14 (0.02-1.2)] and elevated muscle enzymes [0.14 (0.04-0.5)] were negatively associated with calcinosis. Treatment with pamidronate had a good to moderate response to calcinosis in five of seven children. Calcinosis in JDM is associated with long-standing, poorly controlled disease, and the use of bisphosphonates like pamidronate offer promise in the future for its treatment.

Assessment of Enterovirus Excretion and Identification of VDPVs in Patients with Primary Immunodeficiency in India: Outcome of ICMR-WHO Collaborative Study Phase-I.

The emergence of vaccine-derived polioviruses (VDPVs) in patients with Primary Immunodeficiency (PID) is a threat to the polio-eradication program. In a first of its kind pilot study for successful screening and identification of VDPV excretion among patients with PID in India, enteroviruses were assessed in stool specimens of 154 PID patients across India in a period of two years. A total of 21.42% of patients were tested positive for enteroviruses, 2.59% tested positive for polioviruses (PV), whereas 18.83% of patients were positive for non-polio enteroviruses (NPEV). A male child of 3 years and 6 months of age diagnosed with Hyper IgM syndrome was detected positive for type1 VDPV (iVDPV1) with 1.6% nucleotide divergence from the parent Sabin strain. E21 (19.4%), E14 (9%), E11 (9%), E16 (7.5%), and CVA2 (7.5%) were the five most frequently observed NPEV types in PID patients. Patients with combined immunodeficiency were at a higher risk for enterovirus infection as compared to antibody deficiency. The high susceptibility of PID patients to enterovirus infection emphasizes the need for enhanced surveillance of these patients until the use of OPV is stopped. The expansion of PID surveillance and integration with a national program will facilitate early detection and follow-up of iVDPV excretion to mitigate the risk for iVDPV spread.

Severe thrombocytopenia is associated with high mortality in systemic lupus erythematosus-analysis from Indian SLE Inception cohort for Research (INSPIRE).

Thrombocytopenia in patients with systemic lupus erythematosus (SLE) is associated with higher morbidity and mortality. We report frequency, associations and short-term outcome of moderate-severe thrombocytopenia in a prospective inception cohort from India (INSPIRE). We evaluated consecutive SLE patients classified per SLICC2012 for the occurrence of thrombocytopenia and its associations. The outcomes assessed included bleeding manifestations, kinetics of thrombocytopenia recovery, mortality and recurrence of thrombocytopenia. Among a total of 2210 patients in the cohort, 230 (10.4%) had incident thrombocytopenia, of whom moderate (platelet count [PC] 20-50 × 109/L) and severe thrombocytopenia (PC < 20 × 109/L) were noted in 61 (26.5%) and 22 (9.5%), respectively. Bleeding manifestations were generally limited to the skin. Compared to controls, cases had a higher proportion of autoimmune haemolytic anaemia (p < 0.001), leukopenia (p < 0.001), lymphopenia (p < 0.001), low complement (p < 0.05), lupus anticoagulant (p < 0.001), higher median SLEDAI 2 K (p < 0.001) and lower proportion of anti-RNP antibody (p < 0.05). There was no significant difference in these variables between moderate and severe thrombocytopenia. There was a sharp rise in PC by 1 week that was sustained in the majority through the period of observation. There was three times higher mortality in the severe thrombocytopenia group as compared to moderate thrombocytopenia and controls. The thrombocytopenia relapse and lupus flare rates were similar across categories. We report a low occurrence of major bleeds and higher mortality in those with severe thrombocytopenia as compared to moderate thrombocytopenia and controls. Key Points • Severe thrombocytopenia occurs in 1% of patients with SLE; however, major bleeds are uncommon. • Thrombocytopenia has a strong association with other lineage cytopenias and lupus anticoagulants. • Response to initial glucocorticoids therapy is quick and is well sustained with additional immunosuppressants. • Severe thrombocytopenia increases mortality threefold in SLE.

Childhood rheumatic diseases: bites not only the joint, but also the heart.

Cardiovascular involvement in juvenile rheumatic diseases is the primary manifestation in paediatric vasculitis and a major organ manifestation in paediatric connective tissue diseases. Though coronary vasculitis is the prototypical manifestation of Kawasaki disease, it can also be seen in patients with polyarteritis nodosa. Pericarditis is the most common manifestation seen in juvenile rheumatic diseases like systemic onset JIA, and lupus. Cardiac tamponade, valvular insufficiency, aortic root dilatation and arrhythmias are seen rarely. Cardiac involvement is often recognized late in children. The development of cardiac disease in juvenile systemic sclerosis is associated with a poor outcome. In long term, childhood onset of rheumatic diseases predisposes to diastolic dysfunction and premature atherosclerosis during adulthood. Key Points • Pericarditis is the most common cardiac manifestation in SLE and can lead to tamponade. • Conduction defects are common in juvenile mixed connective tissue disease and systemic sclerosis. • Pulmonary hypertension is a significant contributor to mortality in juvenile systemic sclerosis. • In Kawasaki disease, early treatment can reduce risk of coronary artery aneurysms.

International cohort of 382 children with lupus nephritis - presentation, treatment and outcome at 24 months.

BACKGROUND: Children with lupus have a higher chance of nephritis and worse kidney outcome than adult patients. METHODS: We retrospectively analyzed clinical presentation, treatment and 24-month kidney outcome in a cohort of 382 patients (≤ 18 years old) with lupus nephritis (LN) class ≥ III diagnosed and treated in the last 10 years in 23 international centers. RESULTS: The mean age at onset was 11 years 9 months and 72.8% were females. Fifty-seven percent and 34% achieved complete and partial remission at 24-month follow-up, respectively. Patients with LN class III achieved complete remission more often than those with classes IV or V (mixed and pure). Only 89 of 351 patients maintained stable complete kidney remission from the 6th to 24th months of follow-up. eGFR ≥ 90 ml/min/1.73 m2 at diagnosis and biopsy class III were predictive of stable kidney remission. The youngest and the oldest age quartiles (2y-9y, 5m) (14y, 2m-18y,2m) showed lower rates of stable remission (17% and 20.7%, respectively) compared to the two other age groups (29.9% and 33.7%), while there was no difference in gender. No difference in achieving stable remission was found between children who received mycophenolate or cyclophosphamide as induction treatment. CONCLUSION: Our data show that the rate of complete remission in patients with LN is still not high enough. Severe kidney involvement at diagnosis was the most important risk factor for not achieving stable remission while different induction treatments did not impact outcome. Randomized treatment trials involving children and adolescents with LN are needed to improve outcome for these children. A higher resolution version of the Graphical abstract is available as Supplementary information.

Tuberculosis remains a leading contributor to morbidity due to serious infections in Indian patients of SLE.

INTRODUCTION: Infections are a major cause of morbidity and mortality in systemic lupus erythematosus (SLE). We assessed the incidence and risk factors for major infections in SLE in India. METHODS: A retrospective review of a cohort of 1354 patients of adult SLE (ACR 1997 criteria) seen between 2000 and 2021 at a single center was conducted. Serious infections (need for hospitalisation, prolonged intravenous antibiotics, disability, or death) were recorded. Cox regression was used to determine factors associated with serious infection and the effects of serious infection on survival and damage. RESULTS: Among the 1354 patients (1258 females, mean age of 30.3 years, follow-up of 7127.89 person-years), there were 439 serious infections in 339 patients (61.6 per 1000 person-years follow-up). Bacterial infections (N = 226) were the most common infection followed by mycobacterial infections (n = 81), viral (n = 35), and then invasive fungal infections (N = 13). Mycobacterium tuberculosis was the single most common microbiologically confirmed organism with incidence of 1136.4/100,000 person-years with 72.8% of them being extrapulmonary. Infection free survival at 1 year and 5 years was 82.9% and 73.8%. There were 119 deaths with infection attributable mortality in 65 (54.6%). On multivariable Cox regression analysis, higher baseline activity (HR 1.02, 1.01-1.05), gastrointestinal involvement (HR 2.75, 1.65-4.69), current steroid dose (HR 1.65, 1.55-1.76), and average cumulative steroid dose per year (HR 1.007, 1.005-1.009) were associated with serious infection and higher albumin (HR 0.65, 0.56-0.76) was protective. Serious infections led to greater damage accrual (median SLICC damage index of 1 vs. 0) and mortality (HR was 18.2, 32.7 and 81.6 for the first, second, and third infections). CONCLUSION: Serious infections remain a major cause of mortality and damage accrual in SLE and higher disease activity, gastrointestinal involvement, hypoalbuminemia, current steroid dose, and cumulative steroid dose are the risk factors for it.

Clusters based on demography, disease phenotype, and autoantibody status predicts mortality in lupus: data from Indian lupus cohort (INSPIRE).

OBJECTIVES: SLE is associated with significant mortality, and data from South Asia is limited. Thus, we analysed the causes and predictors of mortality and hierarchical cluster-based survival in the Indian SLE Inception cohort for Research (INSPIRE). METHODS: Data for patients with SLE was extracted from the INSPIRE database. Univariate analyses of associations between mortality and a number of disease variables were conducted. Agglomerative unsupervised hierarchical cluster analysis was undertaken using 25 variables defining the SLE phenotype. Survival rates across clusters were assessed using non-adjusted and adjusted Cox proportional-hazards models. RESULTS: Among 2072 patients (with a median follow-up of 18 months), there were 170 deaths (49.2 deaths per 1000 patient-years) of which cause could be determined in 155 patients. 47.1% occurred in the first 6 months. Most of the mortality (n = 87) were due to SLE disease activity followed by coexisting disease activity and infection (n = 24), infections (n = 23), and 21 to other causes. Among the deaths in which infection played a role, 24 had pneumonia. Clustering identified four clusters, and the mean survival estimates were 39.26, 39.78, 37.69 and 35.86 months in clusters 1, 2, 3 and 4, respectively (P < 0.001). The adjusted hazard ratios (HRs) (95% CI) were significant for cluster 4 [2.19 (1.44, 3.31)], low socio-economic-status [1.69 (1.22, 2.35)], number of BILAG-A [1.5 (1.29, 1.73)] and BILAG-B [1.15 (1.01, 1.3)], and need for haemodialysis [4.63 (1.87,11.48)]. CONCLUSION: SLE in India has high early mortality, and the majority of deaths occur outside the health-care setting. Clustering using the clinically relevant variables at baseline may help identify individuals at high risk of mortality in SLE, even after adjusting for high disease activity.

Antibody response to ChAdOx1 nCoV-19 (Covishield®) vaccine in people on maintenance hemodialysis.

INTRODUCTION: People on renal replacement therapy (RRT) have a high risk of COVID-19 infection and subsequent death. COVID-19 vaccination is strongly recommended for those on RRT. Data are limited on the immune response of the ChAdOx1 nCoV-19/AZD1222 (Covishield®) vaccine in patients on RRT. METHODS: A prospective cohort of adult (age > 18 years), on RRT in the form of hemodialysis were included and received two intramuscular doses of Covishield®. A blood specimen of 5.0 mL was collected at two time points, within a few days before administering the first dose of the vaccine and at 4-16 weeks after the second dose. According to their prior COVID-19 infection status, the participants were grouped as (i) prior symptomatic COVID-19 infection, (ii) prior asymptomatic COVID-19 infection, and (iii) no prior COVID-19 infection. RESULTS: A large proportion (81%) of participants had anti-spike antibodies (ASAb) before vaccination, and a reasonable proportion (30%) also had neutralizing antibodies (NAb). The titer of ASAb was relatively low (207 U/mL) before vaccination. The ASAb titer (9405 [1635-25,000] U/mL) and percentage of NAb (96.4% [59.6-98.1%]) were markedly increased following the administration of two doses of the vaccine. The participants' prior COVID-19 exposure status did not influence the rise in ASAb titer and NAb percentage. Further, administering two doses of the Covishield vaccine helps them achieve a high ASAb titer. CONCLUSION: Two doses of ChAdOx1 nCoV-19/AZD1222 (Covishield®) vaccine, given 12 weeks apart, achieve a high titer of ASAb and a high percentage of NAb in people on hemodialysis.

Higher Prevalence of Monogenic Cause Among Very Early Onset Inflammatory Bowel Disease in Children: Experience From a Tertiary Care Center From Northern India.

BACKGROUND: Very early-onset inflammatory bowel disease (VEO-IBD) is generally defined as onset of IBD at <6 years of age. Up to 20% of VEO-IBD may have a monogenic cause; hence, next-generation sequencing is highly recommended for diagnostic accuracy. There remains a paucity of data on VEO-IBD and the proportion of monogeneic causes in South Asia. We analyzed our tertiary care center experience of monogenic VEO-IBD from Northern India and compared them with nonmonogenic VEO-IBD to find out the factors that differentiate monogenic from nonmonogenic VEO-IBD. METHODS: All children (<18 years of age) diagnosed with IBD between January 2010 to July 2021 were analyzed along with the next-generation sequencing data and functional assays when available. Clinical features and outcomes between monogenic and nonmonogenic VEO-IBD were compared. RESULTS: A total of 200 children with a median age of 15.3 (range, 0.17-17) years, 125 of whom were boys, were diagnosed to have IBD during the study period. VEO-IBD was seen in 48 (24%) children. Monogenic IBD was diagnosed in 15 (31%) children with VEO-IBD and 7.5% of all IBD cases. The causes of monogenic VEO-IBD included disorders of the immune system (including interleukin-10 receptor mutations) in 12 and epithelial barrier dysfunction in 3. Features that differentiated monogenic from nonmonogenic VEO-IBD were neonatal IBD, presence of perianal disease, IBD unclassified, history of consanguinity and sibling death, wasting, and stunting (P < .05). There were 6 deaths. CONCLUSIONS: One-third of participants were monogenic among Indian children with VEO-IBD, the highest proportion reported to date in the world. Next-generation (either exome or whole genome) sequencing should be recommended in a subset of VEO-IBD with neonatal onset, perianal disease, history of consanguinity and siblings' death, wasting, stunting, and IBD unclassified phenotype for an early diagnosis and referral to an appropriate center for hematopoietic stem cell transplantation for a better outcome.

Of 200 children with inflammatory bowel disease (IBD), 48 were very early-onset IBD (VEO-IBD) and 15 (32%) of them had monogenic VEO-IBD. Clinical features that differentiated monogenic from nonmonogenic VEO-IBD were neonatal onset, perianal disease, history of consanguinity and sibling death, wasting, stunting, and IBD unclassified phenotype.

Etiology, clinical characteristics and mortality among Indian patients with Addison's disease.

The etiology, presentation and mortality of patients with primary adrenal insufficiency (PAI) in developing countries may differ from economically developed nations. However, information in this regard is scanty. The aim of this study was to determine the etiology and compare the clinical characteristics and mortality in infectious and autoimmune causes of PAI in Indian patients. All eligible (n = 89) patients (ages 15-83 years) diagnosed with PAI between 2006 and 2019 were studied. Patients were followed for a median duration of 5.9 (range 0.1-15.7) years. Eighty-six subjects underwent an abdominal computerized tomography scan or ultrasonography, and adrenal biopsy was performed in 60 patients. The most frequent etiologies of PAI were adrenal histoplasmosis (AH, 45%), adrenal tuberculosis (AT, 15%), autoimmunity (AI, 25%) and primary lymphoma (6%). Forty-two percent of patients presented with an acute adrenal crisis. AH and AT could not be differentiated on the basis of clinical features, except for a greater frequency of hepatomegaly-splenomegaly and type 2 diabetes mellitus (63% vs 15%, P < 0.01) in the former. Patients with an autoimmune etiology had a higher frequency of 21-hydroxylase antibodies (41% vs 3%) and autoimmune thyroid disease (46% vs 5%) vs those with infectious etiologies. Mortality was significantly higher in AH (45%) compared with AT (8%) or AI (5%) (P = 0.001). Causes of death included adrenal crises, progressive AH and unexplained acute events occurring at home. In conclusion, infections, especially AH, were the most frequent cause of PAI in north India. Despite appropriate therapy, AH had very high mortality as compared with AT and AI.

Clinical and serological association of plasma 25-hydroxyvitamin D (25(OH)D) levels in lupus and the short-term effects of oral vitamin D supplementation.

BACKGROUND AND OBJECTIVES: Data on the association of vitamin D levels and clinical phenotype and disease activity in systemic lupus erythematosus (SLE) is controversial. Further, the optimal dose of oral vitamin D supplementation in SLE is not clear. Thus, the present study was designed to determine the association of plasma vitamin D levels with clinical phenotype, disease variables and serology in a large, cohort of SLE from South Asia and to evaluate the short-term effect of two different dosage regimens of oral vitamin D supplementation on disease flares and plasma vitamin D levels. METHODS: This is a two-phase study. Phase I was a cross-sectional analytical study of patients from north (26.85° N) and south India (11.94° N). Plasma 25-hydroxyvitamin-D(25(OH)D) was measured, and its association with demography, serology, disease activity, Galectin-9 and CXCL-10 was analysed. In phase II, patients with SLEDAI-2KG < 10 and on stable immunosuppression were randomised to receive either high dose (weekly 60,000 U*5, followed by 60,000 U monthly) or routine dose (30,000 U monthly) oral vitamin D. Outcomes were assessed at 6 months RESULTS: Phase I included 702 patients with a mean age of 29.46 + 10.7 years. The median plasma vitamin D was 22.83 (13.8-31.8) ng/ml. Deficiency (< 20 ng/ml) was seen in 41.5% of patients. Patients from South India had higher vitamin D levels (27.06 ± 20.21 ng/dl) as compared to North India (17.15 ± 16.07 ng/ml) (p < 0.01). Univariate analyses demonstrated weak negative correlation of vitamin D with SLEDAI2K and positive correlation with age. Galactin-9 had modest correlation with SLEDAI2K but not with vitamin D levels. On multiple linear regression, centre of recruitment (ß = 4.37) and age (ß = 0.18) predicted (p < 0.05) plasma vitamin D levels. In the phase II, 91 randomised to 2 groups completed 6 months. Median change in plasma vitamin D levels was more in high dose (9.5 versus 2.6 ng/ml; p = 0.04). There were 14 SLE flares and six minor adverse events which were equal across both groups. CONCLUSION: Vitamin D deficiency is common in SLE. Geographical location of residence is the major determinant rather than the disease activity. The IFN regulated proteins reflect disease activity independent of vitamin D levels. High-dose oral vitamin D supplementation seems safe and more effective in improving vitamin D levels in SLE. TRIAL REGISTRATION: The second phase of this study was a registered randomised controlled trial CTRI/2019/06/019658 [registered on: 14/06/2019].
