The time of equipoise on the use of biological DMARDs in for inflammatory arthritis during pregnancy is finally over: a reappraisal of evidence to optimise pregnancy management.

Active inflammatory arthritis in pregnancy is associated with an increased risk of adverse pregnancy outcomes. Treatment of active inflammation and maintenance of low disease activity with medication reduces these risks. Therapeutic decisions on disease-modifying antirheumatic drugs (DMARDs) in pregnancy are complicated by safety concerns, which have led to inappropriate withdrawal of treatment and consequential harm to mother and fetus. Studies of inflammatory arthritis in pregnancy have consistently shown minimal safety concerns with the use of biological DMARDs and an increased risk of disease flare with discontinuation of biological DMARDs. It is our opinion that during pregnancy, the benefits of disease control with biological DMARDs, when required in addition to conventional synthetic DMARDs, outweigh the risks. In this Series paper, we review the reasons for reconsideration of equipoise and propose an agenda for future research to optimise the use of biological DMARDs in inflammatory arthritis during pregnancy.

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.

Rheumatoid arthritis synovial fluid shows enrichment of T-cells producing GMCSF which are polyfunctional for TNFα and IFNγ.

OBJECTIVES: GMCSF+T-cells may be involved in pathogenesis of rheumatoid arthritis (RA), and polyfunctionality may be a marker of pathogenicity. Although, higher frequencies of CD4+GMCSF+ T-cells have been reported, there are no data on CD8+GMCSF+ T-cells or polyfunctionality.Our objective was to enumerate frequencies of CD8+GMCSF+ T cells in RA blood and synovial fluid (SF), and assess their polyfunctionality, memory phenotype and cytotoxic ability. METHODS: This study included RA patients (blood samples,in some with paired synovial fluid (SF)), healthy controls (HC) (blood) and SpA patients (SF). In some RA patients' blood was sampled twice, before and 16-24 weeks after methotrexate (MTX) treatment. After mononuclear cell isolation from blood and SF, ex-vivo stimulation using PMA/Ionomycin was done, and cells were stained (surface and intracellular after permeabilisation/fixation). Subsequently, frequencies of GMCSF+CD8+ and CD4+ T-cells, polyfunctionality (TNFα, IFNγ, IL-17), phenotype (memory) and perforin/granzyme expression were assessed by flowcytometry. RESULTS: There was no significant difference in frequencies of GMCSF+CD8+ (3.7, 4.1%, p=0.540) or GMCSF+CD4+ T-cells (4.5, 5.2%, p=0.450) inblood of RA and HC. However, there was significant enrichment of both CD8+GMCSF+ (5.8, 3.9%, p=0.0045) and CD4+GMCSF+ (8.5, 4.5%, p=0.0008) T-cells inSF compared to blood in RA patients. Polyfunctional triple cytokine positive TNFα+IFNγ+GMCSF+CD8+T-cells (81, 36%, p=0.049) and CD4+T-cells (48, 32%, p=0.010) was also higher in SF compared to blood in RA. CD8+ T cells showed higher frequency of effector-memory phenotype and granzyme-B expression in RA-SF. On longitudinal follow-up, blood CD4+GMCSF+ T-cells significantly declined (4.6, 2.9%, p=0.0014) post-MTX. CONCLUSIONS: We report a novel finding of enrichment of CD8+GMCSF+ in addition to CD4+GMCSF+ T-cells in RA-SF. These cells showed higher polyfunctionality for TNFα and IFNγ, and effector memory phenotype suggesting their involvement in RA pathogenesis.

Long-term persistence of oral methotrexate and associated factors in rheumatoid arthritis: a retrospective cohort study.

There is little data on long-term persistence/continuation of methotrexate among Indian Rheumatoid arthritis patients. We assembled a retrospective single-center cohort consisting of RA patients (fulfilling 1987 ACR criteria) started on methotrexate as part of three academic studies (including two RCTs) from 2011 to 2016. Oral methotrexate was started at 7.5 or 15 mg per week with a target dose of 25 mg per week. Between August and December 2020, all patients were contacted (telephonically) and data were obtained from clinic files to evaluate self-reported continuation/persistence of methotrexate and reasons for discontinuation. Survival analysis using Kaplan-Meier and cox-regression were used to assess methotrexate continuation rates and factors associated with its discontinuation. This study included 317 patients with rheumatoid arthritis, with mean age and disease duration (at enrollment) of 43 years and 2 years; And positive rheumatoid factor and anti-CCP in 69 and 75%. At follow-up, 16 patients (5%) had died, whereas 103 (32.5%) had discontinued methotrexate. On Kaplan-Meier survival analysis, the mean survival (continuation) time for methotrexate was 7.3 years (95% CI 7-7.6 years). The actuarial continuation/persistence of methotrexate at 3, 5 and 9 years was 92, 81 and 51%, respectively. Among those who discontinued methotrexate, common reasons were remission of disease, symptomatic adverse effects (intolerance), perceived lack of efficacy and socioeconomic reasons. On multivariable cox-regression, symptomatic adverse effects during the first 12-24 weeks (Hazard ratio, 95% CI 1.8 (1.2-2.8)) and anti-CCP positivity (Hazard ratio, 95% CI 0.6 (0.3-1.0)) were significantly associated with hazard of discontinuation. Persistence or continuation of methotrexate was found to be good and comparable to reports in other centers world-wide. Apart from remission, the most important cause of methotrexate discontinuation was symptomatic adverse effects (intolerance).

Antinuclear antibody pattern and autoantibody profiling of systemic sclerosis patients in a tertiary referral center in North India.

Antinuclear antibody (ANA) pattern and autoantibody (autoAb) profiling of 150 adult systemic sclerosis (SSc) patients concerning their clinical association and diagnostic significance were analyzed by indirect immunofluorescence (IIF), immunoblot, and fluorescence enzyme immunoassay. One hundred and forty-three (95.3%) patients had positive ANA: DNA topoisomerase I (topo I)-like pattern-84(56%); speckled pattern-44(29.3%);centromere pattern-7(4.6%); and nucleolar pattern-4(2.6%). Three distinct topo I-like immunofluorescence patterns were detected at 1:40 dilution. Topo I-like pattern (32/75-limited cutaneous systemic sclerosis (lcSSc) vs. 52/75-diffuse cutaneous systemic sclerosis (dcSSc); p < 0.001) was found to be associated with dcSSc subset and speckled pattern (lcSSc 28/75 vs. dcSSc 16/75; p < 0.03) with lcSSc subset. One hundred and thirty-eight (92%) patients were positive for SSc-associated autoAbs. The frequency distribution of autoAbs to topo I, centromere A (CENP A) and centromereB (CENP B), RNA polymerase III (RP11, RP155), fibrillarin (U3RNP), nucleolus organizer region (NOR)-90, Th/To, PM-Scl75, PM-Scl100, Ku, platelet-derived growth factor receptor (PDGFR) and Ro-52, were 87(58%), 9(6%), 8(5.3%), 6(4%), 9(6%), 0, 6(4%), 6(4%), 8(5.3%), 5(3.3%), 11(7.3%),0 and 46(30.6%), respectively. Topo I autoAb was strongly associated with dcSSc (35/75 lcSSc vs. 52/75 dcSSc; p < 0.004), Raynaud's (p < 0.003), interstitial lung disease (ILD) (p < 0.001) and pulmonary arterial hypertension (PAH) (p < 0.04). This study helps in defining SSc clinical subset, prognostic markers of disease severity, characterization of the topo I-like ANA pattern, and provides a definite association between the ANA patterns and corresponding autoAb.

Hydroxychloroquine in Treatment of Asymptomatic and Mildly Symptomatic COVID-19: A Multi-Centre Cohort Study.

BACKGROUND: Although hydroxychloroquine (HCQ) lacks benefit in patients with moderate-to-severe COVID-19, its role in asymptomatic and mildly symptomatic disease needs better elucidation. METHODS: This multi-centre cohort study included asymptomatic and mildly symptomatic, RT-PCR confirmed COVID-19 cases between 30 March and 20 May, 2020. Patients were categorized into two groups (HCQ-treated and untreated) based on exposure to HCQ. Dose of HCQ used was 400 mg twice daily (day one) followed by once daily for seven days. HCQ-untreated patients were managed supportively without any active antiviral or immunomodulatory therapy. Nasopharyngeal SARS-CoV-2 clearance by RT-PCR (primary outcome) was compared between HCQ-treated and untreated patients using Kaplan-Meier analysis and Cox proportional-hazards regression. Clinical efficacy and safety profile of HCQ were assessed (secondary outcomes). RESULTS: 162 patients [84 (51·9%) males; mean age 38·2 (15·2) years] were included. Forty-four (27·2%) patients had mild disease, rest 118 (72·8%) were asymptomatic. Seventy-five (46·3%) patients received HCQ. Median time to virological negativity was lesser in HCQ-treated (13 days) versus untreated patients (15 days) (logrank<0·001) in both asymptomatic and mildly symptomatic patients. Treatment with HCQ was the only independent predictor of virological negativity (hazardratio=2·24; adjusted p-value<0·001). Two (5·4%) mildly symptomatic patients progressed to severe disease within 24 hours (two doses) of HCQ initiation, compared to none in the HCQ-untreated group. Five HCQ-treated patients developed minor gastrointestinal side effects, not requiring drug discontinuation. CONCLUSION: HCQ reduced the time to virologic negativity (by 2 days) in asymptomatic and mildly symptomatic COVID-19, without any serious adverse events. However, no obvious clinical benefit was noted.

Association of immunological features with clinical manifestations in primary Sjogren's syndrome: a single-center cross-sectional study.

The objectives of this study were to describe the clinical features and evaluate the utility of immunological features as predictors of organ involvement and disease severity in patients with primary Sjogren's syndrome (pSS). In this single-center observational cross-sectional study, subjects fulfilling the 2012 AECG criteria or 2016 ACR/EULAR criteria for pSS were included. Details of glandular, extra-glandular manifestations, ESSDAI, ESSPRI, ANA, anti-Ro/La antibodies, rheumatoid factor (RF), complement (C3 and C4) levels and hyperglobulinemia were noted. Chi-square and Mann-Whitney U tests were performed for determining associations and relative risk (RR) was calculated. Sixty-four subjects with pSS were included in the study. Females constituted 92% and median age at onset was 37.5 (15-74) years. Ocular or oral sicca was noted in 61 (95.3%) subjects and parotidomegaly was noted in 17 (26.5%) subjects. Extra-glandular manifestations noted were: constitutional (85.9%), articular (65.6%), renal (29.6%), hematological (26.6%), cutaneous (12.5%), peripheral nerves (9.3%) and pulmonary (4.7%). Immunological features noted were: ANA (85.9%), anti-Ro (81.3%), anti-La (60.9%), RF (84.4%), hypocomplementemia (39.1%) and hyperglobulinemia (62.5%). Median ESSDAI was 6 (0-23) and ESSPRI was 7 (0-10). ANA was associated with younger age and renal involvement (RR 1.25). Anti-Ro was associated with younger age, renal involvement (RR 1.36) and high ESSDAI. Anti-La was associated with high renal (RR 3.4) and low articular involvement (RR 2.75). RF was associated with hematological involvement and hyperglobulinemia was associated with younger age. Certain immunological features can help predict the organ involvement in patients with pSS. Larger, prospective follow-up studies are needed to clearly understand these associations.

Scleroderma Renal Crisis is Associated with High Mortality: A Real-World Study from India.

INTRODUCTION: Scleroderma renal crisis (SRC) is a life-threatening complication of systemic sclerosis. Since the use of ACE inhibitors in this condition, there has been a significant reduction of mortality rates. However, there is limited data on characteristics and outcomes of SRC from developing countries. METHOD: This was a single centre, case-control study from India. The records of all patients admitted in the last 5 years were scrutinized, and patients with SRC (as per the updated consensus classification, 2014) were compared with patients of systemic sclerosis who were admitted for other reasons (controls). Disease characteristics, between cases and controls, were compared using chi-squared test, and odds ratios (OR) were calculated. Survival was compared using KaplanMeier statistics. RESULTS: Ninety-four patients of systemic sclerosis admitted over five-years; among them 15 had SRC. As compared to controls, those with SRC had a significantly higher rates of pericardial effusion (OR 11.7, p=0.02), dilated cardiomyopathy (OR 2.5, p=0.04), myopathy (OR 19.3, p=0.001), taking mediumhigh dose glucocorticoids (OR 7.9, p=0.009) and recent disease onset (OR 39.3, p=0.01). Despite aggressive control of hypertension with ACE inhibitors, 10/12 patients with SRC died. Mean (SD) survival in patients with SRC (11.5, 95% CI 5.7 to 17.6 months) was significantly lower than controls (66.2, 95% CI 58.4 to 73.9 months, p<0.001). CONCLUSION: In this single-centre study from a developing country, scleroderma renal crisis was associated with a dismal prognosis, despite the use of ACEI. The recent use of medium-high dose glucocorticoids was associated with SRC.

Methotrexate in Early Chikungunya Arthritis: A 6 Month Randomized Controlled Open-label Trial.

OBJECTIVE: Evidence for treating chikungunya arthritis early in the course of illness is scarce. This study assesses the efficacy of Methotrexate in early Chikungunya arthritis. METHODS: It is a randomized controlled open-label assessor-blinded trial with a crossover design. Sixty patients with persistent post chikungunya arthritis with at least 3 or more tender or swollen joints (28 joint count) were recruited. MTX arm was given oral Methotrexate and NSAID arm was given NSAIDs (Naproxen 1 gm/day or Etoricoxib 120 mg/day). Patients were followed at 1, 2, 4 and 6 months. After 2 months patients in NSAID arm who have not achieved remission were given MTX. The primary endpoint was remission (no tender or swollen joints by 28 joint count) at 6 months. Secondary endpoints were change in CDAI, Indian HAQ, total steroid use, total NSAID use, and serious adverse effects. Intention to treat analysis was used. RESULTS: TJC, SJC, CDAI and HAQ were matched between two at baseline. Remission was achieved by 28 patients (93%, CI- 78%-98%) in the NSAID arm and 26 patients (86%, CI-70%- 94%) in MTX arm (p=0.18). There was no significant difference in steroid need, change in HAQ, CDAI, TJC or SJC. Those who have not achieved remission had higher disease activity at baseline. CONCLUSION: A protocol-based approach with steroid and NSAIDs helped to achieve remission in most patients with early subacute phase of post-Chikungunya arthritis and the effect was comparable to that of early initiation of methotrexate.

Esophageal manometry, esophagogastroduodenoscopy, and duodenal mucosal histopathology in systemic sclerosis.

BACKGROUND AND AIM: Systemic sclerosis (SSc) is known to involve the gastrointestinal (GI) tract, resulting in dysmotility, gastroesophageal reflux disease, and mucosal changes causing significant morbidity. The study aimed to assess esophageal motility and duodenal mucosal changes in SSc. METHODS: This is a prospective, cross-sectional, single-center study of 23 patients with SSc diagnosed on the basis of standard criteria. Clinical details including the GI symptoms were recorded. All of them underwent esophagogastroduodenoscopy with duodenal biopsy, and 21 underwent esophageal manometry. RESULTS: Regurgitation, heartburn, and dysphagia were seen in 19 (82%), 16 (69%), and 10 (43%) patients, respectively. On endoscopy, 19 patients (83%) showed changes of reflux esophagitis (4 had grade C esophagitis), and 3 had esophageal candidiasis. Of the 21 patients who underwent esophageal manometry, 13 (62%) had absent peristalsis, 6 (28%) had ineffective peristalsis, and 10 (48%) had hypotensive lower esophageal sphincter (LES). Duodenal biopsy showed partial villous atrophy in 9 (39%) patients, increased intraepithelial lymphocytes in 18 (78%), and excess of mononuclear inflammatory cells in lamina propria in 21 (91%). Partial villous atrophy was seen more commonly in those with abnormal esophageal peristalsis and a hypotensive LES. CONCLUSION: Most of the patients with SSc had esophageal dysmotility in the form of absent peristalsis, ineffective esophageal peristalsis, and hypotensive LES. Histology of descending duodenum demonstrated partial villous atrophy and chronic inflammatory infiltrates in most of the patients with SSc.

Isolated splenic mucormycosis in a case of aplastic anaemia.

Mucormycosis, a rare opportunistic infection seen in immunocompromised hosts, is caused by fungi of Mucorales family. It may be confined to the organs, such as rhinocerebral and pulmonary mucormycosis, or may cause disseminated infection. A 14-year-old boy presented to our clinic with fever and left upper quadrant abdominal pain, and on evaluation was found to have pancytopaenia, and imaging revealed ill-defined splenic collection with thrombus in the splenic vein. He was started on empirical intravenous antibiotics, followed by antifungals empirically as he did not show any improvement clinically. Eventually, splenectomy was done, which on histopathological examination revealed mucormycosis. The patient finally succumbed to his illness as he developed peritonitis and refractory shock. To date, only two cases of isolated splenic mucormycosis have been reported. Aggressive treatment is needed, which includes the use of antifungals (amphotericin B) and surgical debridement or resection of the involved tissues or organs.
