Anakinra in Pyogenic Arthritis, Acne, Pyoderma Gangrenosum, and Suppurative Hidradenitis (PAPASH) Spectrum Disorder: A Case Report and Literature Review.

Pyogenic arthritis, acne, pyoderma gangrenosum, and suppurative hidradenitis (PAPASH); pyogenic arthritis, pyoderma gangrenosum (PG), and acne; PG, acne, hidradenitis suppurativa; and PG, acne, spondylarthritis (PASS) are all part of a spectrum of autoinflammatory disorders that share similar pathogenesis. They are related to various mutations in the proline-serine-threonine phosphatase interacting protein 1, leading to dysregulation of the innate immune system and overproduction of interleukin (IL)-1, IL-17, and IL-23 and tumor necrosis factor (TNF)-α. Targeting these cytokines with biologics plays an important role in treatment. Here, we are describing the case of a young male with PAPASH syndrome who was treated with TNF-α and IL-1 inhibitor.

Canakinumab in Yao Syndrome: Insights From a Comprehensive Case Report and Literature Review .

Yao syndrome, a rare autoinflammatory disorder linked to mutations in the nucleotide-binding oligomerization domain-containing protein-2 (NOD2) gene, manifests through periodic fever, polyarthritis, dermatitis, gastrointestinal disturbances, and sicca-like symptoms. The therapeutic landscape is limited, primarily encompassing glucocorticoids, interleukin-1 (IL-1), and IL-6 inhibitors. This report details the case of a teenager with periodic fevers, arthritis, livedo reticularis, and NOD2 gene mutations R702W and IVS8+158C consistent with Yao syndrome. The individual demonstrated significant improvement with canakinumab therapy. This case report aims to enhance recognition and understanding of Yao syndrome's clinical spectrum and management options.

Chromosomal Variations and Clinical Features of Acute Lymphoblastic Leukemia in the North Indian Population: A Cross-Sectional Study.

BACKGROUND: The key prognostic markers in acute lymphoblastic leukemia (ALL) include age, leukocyte count upon diagnosis, immunophenotype, and chromosomal abnormalities. Furthermore, there was a correlation between cytogenetic anomalies and specific immunologic phenotypes of ALL, which in turn had varied outcomes. The objective of this study was to examine the occurrence of cytogenetic abnormalities in individuals diagnosed with acute lymphoblastic leukemia. METHODS: The study employed a cross-sectional design to investigate genetic evaluation and clinical features in 147 ALL patients between March 2021 and August 2022. Demographic data (like age and sex), clinical manifestations, and hematological parameters were collected. Cytogenetic analysis (G-banding) was performed to identify chromosomal abnormalities. The mean±SD and analysis of variance (ANOVA) were used to assess associations and differences among variables using SPSS Version 24 (IBM Corp., Armonk, NY, USA). RESULTS: The study shows male n=85 and female n=62 in ALL patients, with prevalent clinical manifestations: fever n=100 (68.03%), pallor n=123 (83.67%), and lymphadenopathy n=65 (44.22%). The hematological parameters like hemoglobin (Hb) (6.14±2.5 g/dl), total leukocyte count (TLC) (1.7±1.05 cell/mm3), and platelet count (1.2±0.11 lac/mm3) show a significant variation (P<0.05) in patients aged 30-50 years. In addition, chromosomal abnormalities, particularly 46, XX, t(9;22), were prevalent, emphasizing the genetic heterogeneity of ALL. CONCLUSION: The study shows a male predominance with ALL, prevalent clinical manifestations, and significant hematological parameter variations in the 30-50 age group. Chromosomal abnormalities, notably 46, XX, t(9;22), underscore the genetic complexity of the disease, which necessitates tailored therapeutic interventions informed by genetic profiles.

Correlation between intestinal stem cell niche changes and small bowel crypt failure in patients with treatment-naïve celiac disease.

OBJECTIVES: We hypothesized that crypt failure in the small bowel results in villous flattening in patients with celiac disease (CeD). We investigated whether alterations in the stem cell niche (ISC) are responsible for this phenomenon. MATERIALS AND METHODS: We included 92 duodenal (D2/3) biopsies from treatment-naive patients of CeD and 37 controls. All underwent screening for serum anti-tissue transglutaminase and endoscopic upper small bowel biopsy. Immunohistochemical markers were used to investigate ISC niche alterations, including LGR5 for crypt basal cells (CBC), Bmi1 for position 4+ cells, ß-Defensin for Paneth cells, R-spondin1 as WNT activator, transcription factor-4 as WNT transcription factor, BMP receptor1A as WNT inhibitor, fibronectin-1 as periepithelial stromal cell marker, H2AX as apoptosis marker, and Ki67 as proliferation marker. We also analyzed IgA anti-tTG2 antibody deposits by using dual-color immunofluorescence staining. RESULTS: We found that in biopsies from patients with treatment-naive CeD with modified Marsh grade 3a-3c changes, the epithelial H2AX apoptotic index was upregulated than in controls. LGR5+ crypt basal cells were upregulated in all modified Marsh grades compared to controls. However, the Ki67 proliferation index, expressions of WNT-activator RSPO1, and position-4 cell marker Bmi1 did not significantly alter in patients' biopsies as compared to controls ( P = 0.001). We also observed depletion of pericrypt stromal fibronectin-1 in patients with CeD compared to controls. In addition, we identified IgA anti-TG2 antibody deposits in pericrypt stroma. CONCLUSIONS: Our data suggests that ISC niche failure is a plausible hypothesis for villous flattening in patients with CeD, resulting from pericrypt IgA anti-TG2 antibody complex-mediated stromal depletion.

Barriers at various levels of human ecosystem for maintaining adherence to gluten free diet in adult patients with celiac disease.

INTRODUCTION: While lifelong and strict adherence to gluten-free diet (GFD) is essential for the successful treatment of celiac disease (CeD), only 30-50% of patients are able to maintain a good adherence to GFD. We determined factors influencing the adherence to GFD at various ecological levels including intra-personal, inter-personal, organizational, community and system-based levels in adult patients with CeD. METHODS: A questionnaire to assess the adherence was developed and it was administered in the CeD clinic to patients with CeD on GFD for >1 year. Adherence to GFD was assessed in a subset of patients (n = 320) using Celiac Disease Adherence Test (CDAT). RESULTS: Overall, 978 patients [median age: 29 years; females: 592] with CeD on GFD were recruited. They reported many barriers to adherence to GFD including intra-personal barriers such as lack of knowledge about GFD (19%), inadequate financial resources (27.2%) and lack of self-motivation/confidence (55.3%); inter-personal barriers such as intake of gluten-containing food upon forceful insistence of friends/family (23.4%); organizational barriers such as high cost (70.8%) and non-availability of GF-food products (48.6%); community-based barriers like consumption of gluten-containing food at religious occasions/festivals (11.1%) and social occasions (27.2%); and system-based barriers such as non-referral to dietitian for counseling (21.9%). As per CDAT, 204 (63.7%), 73(22.8%) and 43(13.4%) patients had good, average, and poor adherence to GFD, respectively. On multivariable analysis, occasional consumption of gluten, non-availability of GF-food while dining out and coercing by family and friends for consumption of GC-food were found to have highest odds for poor adherence to GFD. CONCLUSIONS: Non-referral to a dietitian for counseling, irregular follow-up visits, unavailability of flour mill, non-supportive family/friends, high cost and limited availability of GF-food are the most common barriers to adherence to GFD. There is a need to create infrastructure and develop strategies to overcome these diverse barriers at various levels of ecosystem and thereby facilitate better adherence to GFD.

Changes in cardiorespiratory function and fatigue following 12 weeks of exercise training in women with systemic lupus erythematosus: a pilot study.

OBJECTIVE: In patients with systemic lupus erythematosus (SLE), fatigue is a debilitating symptom with poorly understood pathophysiology. Cardiorespiratory dysfunction has been hypothesised as a contributor to SLE-fatigue. The purpose of this exploratory study was to examine changes in cardiorespiratory function, following an exercise training programme in women with SLE, together with patient reported outcomes and other pathophysiological measures that may underlie SLE-fatigue. METHODS: Sixteen women with SLE and fatigue (Fatigue Severity Scale (FSS) ≥3) were enrolled in a supervised aerobic exercise training programme of vigorous intensity. The primary outcome was time to reach anaerobic threshold (AT-Time) during a cardiopulmonary exercise test (CPET). Secondary outcomes included changes in the 10-minute walk test (10MWT), FSS scores and the Patient Reported Outcomes Measurement Information System (PROMIS-57) survey. Mitochondrial function was assessed by the oxygen consumption rate (OCR)/extracellular acidification rate (ECAR) metabolic potential ratio. RESULTS: Following 12 weeks of exercise training, AT-Time increased by 93±82 (mean±SD) s (p<0.001), 10MWT increased by 84±66 m (p<0.001) and peak oxygen uptake (VO2) increased by 1.4±2.0 mL/kg/min (p=0.013). There were improvements in FSS score (-1.4±1.0, p<0.0001) and in most of the PROMIS-57 domains. The decrease in FSS scores correlated with an increase in the OCR/ECAR ratio (Pearson's correlation r=-0.59, p=0.03). A subset of subjects (9/15) had significant reduction in their Interferon Stimulated Genes (ISG) (p=0.007) accompanied by a significant increase in the OCR/ECAR ratio (p=0.013). CONCLUSIONS: Cardiorespiratory function was improved in concomitance with reductions in fatigue following a 12-week aerobic exercise programme. The reduction in fatigue scores correlated with improvements in mitochondrial function.

Incomplete Susac's Syndrome: A Case Report and Literature Review.

Susac syndrome (SS) is rare microangiopathy of unclear etiology involving arteries of the brain, cochlea, and retina, affecting mainly middle-aged women. The diagnosis of Susac syndrome is based on a clinical evaluation of the signs and symptoms supported by imaging modalities. Immunosuppressants are the first-line treatment. Our patient is a 46-year-old man who was evaluated for right-sided visual loss and bilateral hearing loss. His ophthalmic examination revealed retinal artery occlusion. He showed a good response to rituximab and his vision remained stable. Our case is particularly unique as it shows an incomplete Susac syndrome involving the cochlea and retina only. This paper aims to increase awareness about the disease's symptoms, treatment, and prognosis.

An Unusual Side Effect of the COVID-19 Vaccine: A Possible Trigger of Polymyalgia Rheumatica.

Polymyalgia rheumatica (PMR) is characterized by myalgia and severe stiffness with decreased range of motion in the shoulder and pelvic girdles. The efficacy of the BNT 162b2 Pfizer vaccine has been proven and has been well-tolerated by patients; however, some instances of PMR have been reported after the COVID-19 vaccine. We are writing a case of a new-onset PMR in a 72-year-old woman with typical findings after receiving a booster dose of the BNT 162b2 Pfizer vaccine. This case report highlights that PMR should be in the differential diagnosis of myalgias caused by the vaccine.

A Rapidly Debilitating Myopathy: A Rare Case of Statin-Induced Necrotizing Myositis.

Statins are well tolerated in general but can be associated with myopathies. Statin-induced myopathies can range widely from mild myalgias to necrotizing autoimmune myopathies. We present a case of an 81-year-old man on statins for five years with no complications, who developed progressive muscle weakness, rhabdomyolysis, and dysphagia. His laboratory workup revealed elevated inflammatory markers with creatine kinase (CK) levels above 2000 U/L. The myositis panel was negative, and the anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase antibody was positive. His muscle biopsy showed randomly scattered necrotic fibers with minimal perivascular inflammation confirming statin-induced necrotizing autoimmune myopathy (SINAM). Statins were discontinued immediately after initial suspicion. The patient was started on intravenous immunoglobulin followed by hydrocortisone and mycophenolate mofetil. The patient continued to have muscle weakness and progressive dysphagia to the point that he could not handle his secretions. His disease course was complicated by recurrent aspiration pneumonia. Percutaneous endoscopic gastrostomy tube placement was considered, but his family decided on hospice care given his overall comorbidities. Physicians should note that SINAM can occur after a few months to several years of statin use. This disease can be rapidly debilitating and progress even after discontinuation of statins, and treatment requires immunosuppressants, including steroids and steroid-sparing agents.

A Man With Intractable Back Pain, Spondylodiscitis: A Case Report of Uncommon Site of Spinal Gout.

Gout typically affects the peripheral joints but uncommonly can involve the axial skeleton and rarely the intervertebral discs. We present a rare case of gouty spondylodiscitis affecting the intervertebral disc in the lumbar spine. Our patient with a gout history not on any maintenance therapy presented intractable right-sided back pain radiating to the right lower extremity. Computed tomography scan findings were consistent with spondylosis, while magnetic resonance imaging showed concern of infectious discitis. Initially, he was treated for infectious discitis with IV antibiotics. Biopsy of the L5-S1 disc space revealed monosodium urate crystals, confirming the diagnosis of gouty spondylodiscitis. He was managed with IV dexamethasone and recovered well on a tapering dose of steroids and colchicine followed by allopurinol once acute flare resolved.

ELN 2017 Genetic Risk Stratification Predicts Survival of Acute Myeloid Leukemia Patients Receiving Allogeneic Hematopoietic Stem Cell Transplantation.

European LeukemiaNet (ELN) 2017 risk stratification by genetics is prognostic of outcomes in patients with acute myeloid leukemia (AML). However, the prognostic impact of the 2017 ELN genetic risk stratification after allogeneic hematopoietic cell transplantation (alloHCT) is not well established. We examined the effect of 2017 ELN genetic risk stratification on alloHCT outcomes of AML. We included 500 adult (≥18 years) AML patients in first (n = 370) or second (n = 130) complete remission receiving alloHCT from 2005 to 2016. Patients were classified into favorable (12%), intermediate (57%), and adverse (32%) 2017 ELN risk groups. The Cox proportional hazard model was used to conduct the multivariable analyses of leukemia-free survival (LFS) and overall survival (OS). Relapse and nonrelapse mortality were analyzed by the Fine-Gray regression model. OS at 2 years was 72% in the favorable versus 60% in the intermediate versus 45% in the adverse risk groups (P < .001). In multivariable analyses, the 2017 ELN classifier was an independent predictor of OS after alloHCT with significantly higher overall mortality in the intermediate (hazard ratio [HR] = 1.68, 95% confidence interval [CI], 1.06-2.68; P = .03) and adverse (HR = 2.50, 95% CI, 1.54-4.06; P < .001) risk groups compared to the favorable risk group. Similarly, LFS was worse in the intermediate (HR = 1.63, 95%, CI 1.06-2.53; P = .03) and adverse (HR 2.23, 95% CI, 1.41-3.54; P < .001) risk groups while relapse was higher in the adverse risk group (HR = 2.36, 95% CI, 1.28-4.35; P = .006) as compared to the favorable risk group. These data highlight the prognostic impact of the 2017 ELN genetic risk stratification on the survival of AML patients after alloHCT. Patients in the adverse risk group had the highest risk of relapse and worst survival. Thus the 2017 ELN prognostic system can help identify AML patients who may benefit from clinical trials offering relapse mitigation strategies to improve transplant outcomes.

A Man With Recurrent Pneumonitis: A Rare Case of Interstitial Lung Disease Associated With Anti-Mi-2 Beta-Specific Dermatomyositis.

Dermatomyositis (DM) and polymyositis (PM) are idiopathic inflammatory myopathies. Interstitial lung disease (ILD) develops in most patients with DM and PM directly related to morbidity and mortality. Diagnosis requires a myositis panel and high-resolution computed tomography (HRCT). Prognosis depends on specific myositis-specific antibodies and the pattern of the interstitial lung changes. Anti-Mi-2 antibody-specific dermatomyositis has a lower prevalence of interstitial lung disease and has a favorable prognosis, responding well to steroids. Our patient is a 72-year old male who presented with recurrent episodes of pneumonitis, and ILD was found to have anti-Mi-2 beta-specific dermatomyositis and SLE overlap disease. He was responding well to high-dose steroids but was rebounding to similar symptoms whenever steroid weaning was attempted. He was started on azathioprine, but unfortunately, his disease rapidly progressed, and he died within a few months. This manuscript enhances the temporal relationship between dermatomyositis and ILD.

Tiger-like mycosis fungoides: an unusual clinical presentation of a rare variant of mycosis fungoides.

Mycosis fungoides (MF) is the most common type of cutaneous T-cell lymphoma. Mycosis fungoides classically presents in the skin as patches, plaques, tumors, or erythroderma, progressing to involve the lymph nodes and peripheral blood. The many clinical variants, with different histologic patterns, and the subtle early clinical and histologic changes may delay early diagnosis and present a diagnostic challenge for clinicians. The greatest challenge in diagnosis is the pre-mycotic stage, which may closely resemble eczematous or psoriasiform dermatitis clinically and histologically. The persistence of lesions and inadequate response to treatment are the first warning signs. Later stages of MF have a poor prognosis with poor therapeutic response and fatal outcome. We describe a 72-year-old man, who presented with a two-year history of an unusual eruption, which started on the abdomen, around the waistline, and gradually spread to involve his back, trunk, and buttocks. Clinically, the skin eruption presented as tiger-like stripes. The diagnosis was confirmed after histopathologic examination. The patient was treated with NB-UVB phototherapy with marked improvement.

Enabling and hindering factors influencing adherence to asthma treatment among adolescents: A systematic literature review.

OBJECTIVES: The aim of this systematic literature review is to study the enabling and hindering factors influencing adherence to asthma treatment among adolescents. Furthermore, it explores the role of caregivers and the healthcare provider in terms of supporting adolescents to manage and live with asthma. DATA SOURCES: The literature review was conducted using the MeSH terms asthma, adherence, health literacy, behavior, adolescents, tools, healthcare provider, caregiver, peer influence, self-management, quality of life, morbidity and mortality in PubMed, PsycInfo, MEDLINE and CINAHL. STUDY SELECTION: The literature search resulted in 652 articles of which 304 were screened based on title and abstracts. Ninety-one of the screened articles were then selected for full-text assessment resulting in 42 articles for in-depth analysis. RESULTS: The literature review identified nine enabling and hindering factors relevant for adherence to asthma treatment among adolescents: behavior, belief, self-management, health literacy, role of health provider, assessment of adherence, role of caregiver, role of peers and the national asthma guidelines. CONCLUSION: Working with this particular age group is complex and further research in understanding adolescent's behavior, motives, beliefs and perceptions towards adherence to asthma treatment is required to guide them towards better self-management and acceptance of their condition.
