Markers of Endothelial Dysfunction in Kawasaki Disease: An Update.

Kawasaki disease (KD) is a medium vessel vasculitis that has a special predilection for coronary arteries. Cardiovascular complications include the development of coronary artery abnormalities (CAAs) and myocarditis. Endothelial dysfunction (ED) is now recognized to be a key component in the pathogenesis of KD and is believed to contribute to the development of CAAs. ED has been evaluated by several clinical parameters. However, there is paucity of literature on laboratory markers for ED in KD. The evaluation of ED can be aided by the identification of biomarkers such as oxidative stress markers, circulating cells and their progenitors, angiogenesis factors, cytokines, chemokines, cell-adhesion molecules, and adipokines. If validated in multicentric studies, these biomarkers may be useful for monitoring the disease course of KD. They may also provide a useful predictive marker for the development of premature atherosclerosis that is often a concern during long-term follow-up of KD. This review provides insights into the current understanding of the significance of ED in KD.

Wiskott-Aldrich syndrome protein expression in female WAS carriers: A flow cytometry study from North India.

INTRODUCTION: Wiskott-Aldrich syndrome (WAS) is a rare X-linked inborn error of immunity characterized by microthrombocytopenia, infections, eczema, and increased predisposition to develop autoimmunity and malignancy. Flow cytometric assay for determining WAS protein (WASp) is a rapid and cost-effective tool for detecting patients. However, very few studies described WASp expression in female carriers. Most WAS carriers are clinically asymptomatic. Active screening of female family members helps identify female carriers, distinguish de novo mutations, and to select appropriate donor prior to curative stem cell transplantation. This study was undertaken to evaluate the diagnostic capability of flow cytometry-based WASp expression in peripheral blood cells to identify carriers and compare WASp expression in different blood cell lineages. PATIENTS AND METHODS: Female patients, heterozygous for WAS gene, were enrolled in this study conducted at Pediatric Allergy Immunology Unit, Advanced Pediatric Centre, Post Graduate Institute of Medical Education and Research, Chandigarh, India. Flow cytometric assessment of WASp expression in lymphocytes, monocytes, and neutrophils was carried out and compared with healthy control and affected patients. The results were expressed in delta (Δ) median fluorescence intensity (MFI) as well as stain index (SI), which is the ratio of ΔMFI of patient and ΔMFI of control. RESULTS: Thirteen mothers and two sisters of genetically confirmed WAS patients were enrolled in the study. All enrolled females were clinically asymptomatic and did not have microthrombocytopenia. Low WASp expression (SI < 1) was seen in lymphocytes and monocytes in 10 (66.6%) carriers. Females with variants in proximal exons (exons 1 and 2) were found to have lesser expression than those with distal (exons 3-12) variants. CONCLUSION: Flow cytometry is a rapid, easily available, cost-effective tool for WASp estimation. Lymphocytes followed by monocytes are the best cell lineages for WASp estimation in carrier females. However, genetic testing remains the gold standard, as carrier females with variants in distal exons may have normal WASp expression.

Immunoglobulin replacement therapies in inborn errors of immunity: a review.

Immunoglobulins (Ig) were used as a therapeutic modality for the first time in a patient with X-linked agammaglobulinemia in 1952 by Colonel Ogden Bruton, decades before the molecular mechanisms causing the disease were unraveled. In many autoimmune and inflammatory illnesses, human immunoglobulin has been employed as a significant immunomodulatory and immunosuppressive drug. In patients with inborn errors of immunity (IEI), immunoglobulin remains a cornerstone of management. IEIs are notable causes of recurrent infections and autoimmunity due to inheritable single-gene defects in genes encoding for different components of the immune system. As there is decreased immunoglobulin production in IEIs with antibody defects, immunoglobulin replacement is the mainstay of therapy in these disorders. Although serum immunoglobulin levels may not be low in combined immune defects, immunoglobulin replacement is still necessary in these disorders due to a deficiency of functional antibodies and qualitative defects of immunoglobulins. Commercial immunoglobulin preparations are generated from plasma donated by thousands of donors. Immunoglobulin preparations are usually available in two forms: intravenous and subcutaneous immunoglobulins. In the developed world, both intravenous immunoglobulin (IVIg) and subcutaneous immunoglobulin (SCIg) are available, and SCIg is preferred over IVIg for replacement therapy in patients with IEIs. In developing countries, IVIg remains the mainstay of replacement therapy. The rate of adverse events has significantly reduced over the last few years due to advancements in the production process. In this review article, we discuss different aspects of the use of Ig (indications, dosing, mechanism of action, route, adverse effects) in patients with IEIs.

Transmission patterns of C1-INH deficiency hereditary angioedema favors a wild-type male offspring: Our experience at Chandigarh, India.

BACKGROUND: Deficiency of C1-inhibitor (C1-INH) protein, caused by pathogenic variants in the Serpin family G member 1 (SERPING1) gene, is the commonest pathophysiological abnormality (in ∼95 % cases) in patients with hereditary angioedema (HAE). C1-INH protein provides negative control over kallikrein-kinin system (KKS). Although the inheritance of the HAE-C1-INH is autosomal dominant, female predominance has often been observed in patients with HAE. OBJECTIVE: To analyze the risk of transmission of SERPING1 gene variant from father or mother to their offspring. METHODS: Pedigree charts of 42 families with a confirmed diagnosis of HAE-C1-INH and a pathogenic variant in the SERPING1 gene were analysed. Patients with HAE who had had at least one child were included for analyses to assess the risk of transmission from the father or mother to their offspring. RESULTS: Overall, 49 % (189/385) of all offspring inherited the genetic defect. In the subgroup analyses, 54.8 % (90/164) female offspring and 44.8 % (99/221; p < 0.02) male offspring inherited the genetic defect. Inheritance of the genetic defect was significantly lower in male offspring. Fathers with SERPING1 gene variant had a statistically significant skewed transmission of the wild type to the male offspring as compared to the variant (57.8 % wild type vs. 42.1 % variant; p < 0.02), whereas no statistically significant difference was found when a father transmitted the variant to a female offspring. Mothers with SERPING1 gene variant had no statistically significant difference in variant transmission to male or female offsprings. CONCLUSION: Results of the study suggest that the transmission pattern of SERPING1 gene variant favours the transmission of wild-type alleles in males, especially when the father is the carrier; hence, overall, fewer males and more female offspring inherited the variant. This could be because of a selection of wild-type male sperms during spermatogenesis, as the KLK system has been reported to play a crucial role in the regulation of spermatogenesis. Although, a similar pattern was observed in the maternal transmission of the SERPING1 gene variant; the difference was not statistically significant, likely because of a small sample size.

Evening versus morning dosing regimen drug therapy for hypertension.

BACKGROUND: Variation in blood pressure levels display circadian rhythms. Complete 24-hour blood pressure control is the primary goal of antihypertensive treatment and reducing adverse cardiovascular outcomes is the ultimate aim. This is an update of the review first published in 2011. OBJECTIVES: To evaluate the effectiveness of administration-time-related effects of once-daily evening versus conventional morning dosing antihypertensive drug therapy regimens on all-cause mortality, cardiovascular mortality and morbidity, total adverse events, withdrawals from treatment due to adverse effects, and reduction of systolic and diastolic blood pressure in people with primary hypertension. SEARCH METHODS: We searched the Cochrane Hypertension Specialised Register via Cochrane Register of Studies (17 June 2022), Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 6, 2022); MEDLINE, MEDLINE In-Process and MEDLINE Epub Ahead of Print (1 June 2022); Embase (1 June 2022); ClinicalTrials.gov (2 June 2022); Chinese Biomedical Literature Database (CBLD) (1978 to 2009); Chinese VIP (2009 to 7 August 2022); Chinese WANFANG DATA (2009 to 4 August 2022); China Academic Journal Network Publishing Database (CAJD) (2009 to 6 August 2022); Epistemonikos (3 September 2022) and the reference lists of relevant articles. We applied no language restrictions. SELECTION CRITERIA: We included randomised controlled trials (RCTs) comparing the administration-time-related effects of evening with morning dosing monotherapy regimens in people with primary hypertension. We excluded people with known secondary hypertension, shift workers or people with white coat hypertension. DATA COLLECTION AND ANALYSIS: Two to four review authors independently extracted data and assessed trial quality. We resolved disagreements by discussion or with another review author. We performed data synthesis and analyses using Review Manager Web for all-cause mortality, cardiovascular mortality and morbidity, serious adverse events, overall adverse events, withdrawals due to adverse events, change in 24-hour blood pressure and change in morning blood pressure. We assessed the certainty of the evidence using GRADE. We conducted random-effects meta-analysis, fixed-effect meta-analysis, subgroup analysis and sensitivity analysis. MAIN RESULTS: We included 27 RCTs in this updated review, of which two RCTs were excluded from the meta-analyses for lack of data and number of groups not reported. The quantitative analysis included 25 RCTs with 3016 participants with primary hypertension. RCTs used angiotensin-converting enzyme inhibitors (six trials), calcium channel blockers (nine trials), angiotensin II receptor blockers (seven trials), diuretics (two trials), α-blockers (one trial), and ß-blockers (one trial). Fifteen trials were parallel designed, and 10 trials were cross-over designed. Most participants were white, and only two RCTs were conducted in Asia (China) and one in Africa (South Africa). All trials excluded people with risk factors of myocardial infarction and strokes. Most trials had high risk or unclear risk of bias in at least two of several key criteria, which was most prominent in allocation concealment (selection bias) and selective reporting (reporting bias). Meta-analysis showed significant heterogeneity across trials. No RCTs reported on cardiovascular mortality and cardiovascular morbidity. There may be little to no differences in all-cause mortality (after 26 weeks of active treatment: RR 0.49, 95% CI 0.04 to 5.42; RD 0, 95% CI -0.01 to 0.01; very low-certainty evidence), serious adverse events (after 8 to 26 weeks of active treatment: RR 1.17, 95% CI 0.53 to 2.57; RD 0, 95% CI -0.02 to 0.03; very low-certainty evidence), overall adverse events (after 6 to 26 weeks of active treatment: RR 0.89, 95% CI 0.67 to 1.20; I² = 37%; RD -0.02, 95% CI -0.07 to 0.02; I² = 38%; very low-certainty evidence) and withdrawals due to adverse events (after 6 to 26 weeks active treatment: RR 0.76, 95% CI 0.47 to 1.23; I² = 0%; RD -0.01, 95% CI -0.03 to 0; I² = 0%; very low-certainty evidence), but the evidence was very uncertain. AUTHORS' CONCLUSIONS: Due to the very limited data and the defects of the trials' designs, this systematic review did not find adequate evidence to determine which time dosing drug therapy regimen has more beneficial effects on cardiovascular outcomes or adverse events. We have very little confidence in the evidence showing that evening dosing of antihypertensive drugs is no more or less effective than morning administration to lower 24-hour blood pressure. The conclusions should not be assumed to apply to people receiving multiple antihypertensive drug regimens.

X-Linked Lymphoproliferative Syndrome: A Spectrum of Clinical and Immunological Profile and Novel Pathogenic Variants from Chandigarh, India.

INTRODUCTION: X-linked lymphoproliferative syndrome (XLP) is a rare primary immune deficiency. Two types of XLP have been described: XLP-1 and XLP-2. METHODS: We found 7 patients with XLP (3 had XLP-1 and 4 had XLP-2) after reviewing the data from Pediatric Immunodeficiency Clinic from 1997 to 2021. RESULTS: Mean age at diagnosis was 3.8 years, and mean delay in diagnosis was 2.6 years. Five patients had recurrent episodes of infections. Four patients developed at least one episode of hemophagocytic lymphohistiocytosis (HLH) (2 with XLP-1 and 2 with XLP-2). Of these, 2 had recurrent HLH (both with XLP-2). Epstein-Barr virus (EBV) infection was detected in 2 (1 with XLP-1 and 1 with XLP-2). Both these patients had HLH. One child with XLP-2 had inflammatory bowel disease. Hypogammaglobulinemia was seen in 3 (2 with XLP-1 and 1 with XLP-2). Genetic analysis showed previously reported variants in 5, while 2 had novel variants (one in exon 7 of XIAP gene [c.1370dup p.Asn457Lysfs Ter16] and other had splice site variant in intron 1 of SH2D1A gene [c.138-2_138-1insG]). Episodes of HLH were managed with intravenous immunoglobulin (IVIg), methylprednisolone, oral prednisolone, cyclosporine, and rituximab. Inflammatory bowel disease was managed using oral prednisolone and azathioprine. One patient underwent haploidentical hematopoietic stem cell transplantation. One child with XLP-2 and WAS died because of fulminant pneumonia. DISCUSSION/CONCLUSIONS: XLP should be considered as a strong possibility in any patient with features of HLH, repeated infections with hypogammaglobulinemia, persistent EBV infection, and early-onset IBD.

Optochiasmatic Cavernomas: Updated systematic review and proposal of a novel classification with surgical approaches.

Cavernomas are histologically benign vascular malformations found at different sites in the brain. A rare site for such cavernomas, however, is the anterior optic pathway, comprising the optic nerve, chiasma, and optic tract-called optochiasmatic cavernomas (OCC). These lesions usually present with sudden onset or progressive vision loss, headache, and features mimicking pituitary apoplexy. In this paper, we describe a case of OCC operated at our center. We carry out an updated review of literature depicting cases of OCC, their clinical presentation, management, and postoperative complications. We also propose a novel classification system based on lesion location and further analyze these cavernoma types with respect to the surgical approach used and visual outcome. A 30-year-old lady had presented with a 3-week history of progressive bilateral vision loss and headache. Based on imaging, she was suspected to have a cavernous angioma of the chiasma and left optic tract. Due to progressive vision deterioration, the lesion was surgically excised using pterional craniotomy. Postoperatively, her visual symptoms improved, but she developed diabetes insipidus. Clinical and radiological follow-up has been done for 18 months after surgery. A total of 81 cases have been described in the literature, including the present case. Chiasmal apoplexy is the most common presentation. Surgical excision is the standard of care. Our analysis based on lesion location shows the most appropriate surgical approach to be used for each cavernoma type. Visual outcome correlates with the preoperative visual status. Visual outcome is good in patients presenting with acute chiasmal apoplexy, and when complete surgical excision is performed. The endonasal endoscopic approach was found to provide the best visual outcome. In addition to preoperative visual status, complete surgical excision predicts favorable visual outcomes in OCC. Our proposed classification system guides the appropriate surgical approach required for a particular location of the cavernoma.

Alignment efficiency and three-dimensional assessment of root resorption after alignment with conventional and copper-nickel-titanium archwires: A randomized controlled trial.

OBJECTIVE: To compare alignment efficiency and root resorption between nickel-titanium (NiTi) and copper-nickel-titanium (CuNiTi) archwires after complete alignment in mandibular anterior region. METHODS: In this two-arm parallel single-blind randomized controlled trial, forty-four patients with Class I malocclusion with mandibular anterior crowding were recruited form orthodontic clinic of All India Institute of Medical Sciences (Jodhpur, India). Patients were randomly allocated into NiTi and CuNiTi groups, with a 1:1 allocation. Alignment was performed using 0.014-in, 0.016-in, 0.018-in, 0.019x0.025-in archwire sequence in the respective groups, which terminated in 0.019 x 0.025-in stainless-steel working archwire. The primary outcome was alignment efficiency, measured on study models from baseline (T0) to the first, second, third, fourth and fifth-month (T5). Secondary outcome was root resorption, measured from CBCT scans taken at T0 and T5. Mixed-factorial ANOVA was used to compare Little's Irregularity Index (LII). For assessing the proportion of patients with complete alignment at the end of each month, Kaplan-Meier survival curve was built and time to treatment completion was compared between groups using log rank test. Paired t-test was used to assess external apical root resorption (EARR) within groups, whereas independent t-test was used to evaluate LII and EARR between the groups. RESULTS: Twenty-two patients were recruited in each group. One patient was lost to follow-up in the CuNiTi group. No statistically significant differences were observed in alignment efficiency between the groups (p>0.05). Intergroup comparison revealed that the changes in root measurement in three-dimensions were not statistically significant (p>0.05), except for mandibular right central incisor, which showed increased resorption at root apex in NiTi group (p<0.01). CONCLUSION: The two alignment archwires showed similar rate of alignment at all time points. Root resorption measurement did not differ between the NiTi and CuNiTi groups, except for the mandibular right central incisor, which showed more resorption in NiTi group.

Immune and metabolic perturbations in COVID-19-associated pulmonary mucormycosis: A transcriptome analysis of innate immune cells.

BACKGROUND AND OBJECTIVES: The mechanisms underlying COVID-19-associated pulmonary mucormycosis (CAPM) remain unclear. We use a transcriptomic analysis of the innate immune cells to investigate the host immune and metabolic response pathways in patients with CAPM. PATIENTS AND METHODS: We enrolled subjects with CAPM (n = 5), pulmonary mucormycosis (PM) without COVID-19 (n = 5), COVID-19 (without mucormycosis, n = 5), healthy controls (n = 5) without comorbid illness and negative for SARS-CoV-2. Peripheral blood samples from cases were collected before initiating antifungal therapy, and neutrophils and monocytes were isolated. RNA sequencing was performed using Illumina HiSeqX from monocytes and neutrophils. Raw reads were aligned with HISAT-2 pipeline and DESeq2 was used for differential gene expression. Gene ontology (GO) and metabolic pathway analysis were performed using Shiny GO application and R packages (ggplot2, Pathview). RESULTS: The derangement of core immune and metabolic responses in CAPM patients was noted. Pattern recognition receptors, dectin-2, MCL, FcRγ receptors and CLEC-2, were upregulated, but signalling pathways such as JAK-STAT, IL-17 and CARD-9 were downregulated; mTOR and MAP-kinase signalling were elevated in monocytes from CAPM patients. The complement receptors, NETosis, and pro-inflammatory responses, such as S100A8/A9, lipocalin and MMP9, were elevated. The major metabolic pathways of glucose metabolism-glycolysis/gluconeogenesis, pentose phosphate pathway, HIF signalling and iron metabolism-ferroptosis were also upregulated in CAPM. CONCLUSIONS: We identified significant alterations in the metabolic pathways possibly leading to cellular iron overload and a hyperglycaemic state. Immune responses revealed altered recognition, signalling, effector functions and a pro-inflammatory state in monocytes and neutrophils from CAPM patients.

Systematic review analyzing significance of endometrial cavity fluid during assisted reproductive techniques.

OBJECTIVE: The objective of our study is to estimate the prevalence of endometrial cavity fluid (ECF) in Assisted Reproductive Techniques (ART) cycles and analyze its effects on pregnancy outcome in such cycles. DATA SOURCES: PubMed, Cochrane Central, Scopus, and clinicaltrials.gov were searched for articles. The reference lists of relevant publications were explored for other studies. STUDY ELIGIBILITY CRITERIA: Studies that had assessed the pregnancy outcome in ART cycles and had commented on ECF accumulation were included. Pregnancy outcomes were assessed in all ART cycles where ECF was observed and were compared to the non-ECF cycles. RESULTS: A total of nine studies were included in the meta-analysis for a total of 28,210 cycles. Pooled analysis of the prevalence of ECF cycles out of total cycles in females undergoing ART using a fixed effect model showed that it was 14% (95% CI is 13% to 14%; I2 = 99%, p = < 0.01). The random effect model prevalence of ECF cycles was around 7% (95% CI: 4% to 10%). There was a statistically significant (25%) decrease in pregnancy rates per cycle transfer in the ECF cycle versus the non-ECF cycle group during ART [OR = 0.75, 95% CI = 0.67-0.84), p < 0.001; moderate quality evidence]. When ECF size was compared, there was a statistically significant increase in pregnancy rates if ECF size was less than 3.5 mm versus greater than or equal to 3.5 mm [OR = 13.67, 95% CI = 1.43-130.40), p = 0.02; high quality evidence]. Sub-group analysis revealed that the ECF present at the time of embryo transfer significantly decreased the pregnancy rates by 26% as compared to the group where the ECF was not present at the time of embryo transfer [OR = 0.74, 95% CI = 0.65-0.85), p < 0.001]. CONCLUSIONS: This meta-analysis proposes that the presence of ECF significantly decreases the implantation and pregnancy rates of ART cycles, and even more so if its size is greater than 3.5 mm. Interventions to decrease ECF formation or treat it have enhanced the pregnancy outcome in ART cycles. PROSPERO REGISTRATION: Date: 17th September 2020; Number: CRD42020182262.

Clinical, immunological and molecular profiles of DOCK8 deficiency in six patients from a tertiary care centre in North India.

BACKGROUND: Dedicator of cytokinesis protein 8 (DOCK8) deficiency is an autosomal recessive form of combined immunodeficiency. This rare disorder is characterized by an increased predisposition to allergy, autoimmunity and malignancies. OBJECTIVES: To analyse clinical, immunological and molecular profiles of patients with DOCK8 deficiency. METHODS: Clinic records of all patients attending the primary immunodeficiency clinic from 2018 to 2021 were reviewed. Six patients from five families were found to have DOCK8 deficiency. RESULTS: Median age at diagnosis was 7.5 years (range 2-13), with a male/female ratio of 5 : 1. Among the six patients, recurrent eczematous skin lesions were the predominant cutaneous manifestation, present in five patients (83%). Warts and molluscum contagiosum were evident in two patients (33%) and one patient (16%), respectively. Two patients had recalcitrant prurigo nodularis lesions and two had epidermodysplasia verruciformis-like lesions. Food allergies and asthma were reported by one patient each. Of the six patients, recurrent sinopulmonary infections were detected in five (83%). Epstein-Barr virus-driven non-Hodgkin lymphoma with liver metastases was the only case of malignancy, in a 4-year-old boy. IgE was elevated in all patients. Lymphopenia and eosinophilia were observed in three patients (50%) and five patients (83.3%), respectively. Genetic analysis showed DOCK8 pathogenic variants in all patients: homozygous deletion mutations in two patients, compound heterozygous deletion mutations in one, and homozygous nonsense mutations in two. A novel pathogenic homozygous missense variant in the DOCK8 gene was identified in one patient. CONCLUSIONS: DOCK8 deficiency should be considered as a possibility in any patient with early onset eczema, cutaneous viral infections and increased predisposition to allergy, autoimmunity and malignancy.

Electronic-PRO Measures for adverse events Of Treatment In ONcology (E-PROMOTION).

PURPOSE: Cancer patients struggle with the trauma of the disease and its treatment. PRO-CTCAE was developed to improve the recording of underreported symptomatic toxicities. We evaluated the improvement and ease in reporting symptomatic adverse events through add-on PRO-CTCAE (via a mobile application) compared to standard clinician-reported outcomes in routine clinical practice. We also evaluated changes in the health-related quality of life (HRQoL). METHODS: 110 cancer patients were studied for three weeks between their first and second chemotherapy session. HRQoL was assessed using EORTC QLQ-c30. RESULTS: Fifty-three patients self-reported their symptomatic adverse events on the day 7th & day 14th after the first cycle of chemotherapy. For the other fifty-seven patients, recording of adverse events was done by standard clinician-reported outcomes. All the patients in the study group reported adverse events compared to only 21 % in the standard reporting group. All 15 domains of adverse events were reported in the self-reporting group compared to only 5 in the standard reporting group. The self-reporting group had a significantly better overall quality of life. CONCLUSIONS: Self-reporting of adverse events using mobile app-based PRO-CTCAE helps patients and clinicians with better documentation of symptomatic toxicities of chemotherapy, reducing the burden on physicians and improving patient satisfaction. Mobile app-based self-reporting empowers cancer patients undergoing treatment, improves their quality of life, and should be implemented in routine clinical practice. Wider implementation can lead to further optimised solutions.

A systematic review and meta-analysis of tolerability, cardiac safety and efficacy of inclisiran for the therapy of hyperlipidemic patients.

BACKGROUND: Dyslipidaemia is a crucial risk factor for cardiovascular morbidity and mortality. A short interfering RNA called inclisiran diminishes circulating levels of PCSK9 and LDL-C by hindering PCSK9 translation in the liver. METHODS: RCTs were electronically searched on PubMed, Cochrane Central, and Clinicaltrials.gov to assess the safety and efficacy of inclisiran. Cochrane Review Manager 5 was used to conduct the pooled analysis. Risk of bias was assessed and GRADE pro-GDT was utilized, respectively, to estimate the methodological quality and overall quality of evidence. RESULTS: Of 218 records screened, four studies were included with 2203 participants in inclisiran and 1949 participants in the placebo group. Inclisiran was related to non-significant elevated risk of total adverse events[RR = 1.05(0.98,1.12), p = 0.16; I2 = 53%], non-serious adverse events[RR = 1.09(0.97,1.22),p = 0.15;I2 = 61%] and all-cause mortality[RR = 1.01(0.60,1.70),p = 0.97;I2 = 0%] whereas a lower risk of serious adverse events[RR = 0.94(0.70,1.25),p = 0.67;I2 = 73%], cardiac disorders [RR = 0.87(0.66,1.15),p = 0.33;I2 = 42%] and Major adverse cardiovascular events(MACE)[RR = 0.79(0.62,1.00),p = 0.05; I2 = 0%] as compared to placebo. Inclisiran was also linked to a substantial decline in the percentage of LDL-C, PCSK9, total cholesterol, and Apo B. CONCLUSION: The pooled analysis of the existing evidence shows that inclisiran showed reduced risk of MACE along with excellent efficacy in managing dyslipidemia. CLINICAL TRIAL REGISTRATION: www.clinicaltrials.gov identifiers are NCT03399370, NCT03397121, NCT03400800, and NCT02597127.

Elevated cholesterol levels have been found to be associated with a high risk of heart disease and associated deaths. There are various classes of drugs used to control high low-density lipoprotein cholesterol (LDL-C) levels in blood yet appropriate control and patient compliance, to regular cholesterol-lowering drugs have been an issue. Inclisiran, a novel drug for reducing the LDL-C levels in serum can be given every six months as an effective therapy to minimize the levels of LDL-C in serum. This study was designed to assess the safety and effectiveness of inclisiran in patients with hyperlipidemia. Inclisiran was found to have a non-significant elevated risk of total adverse events, non-serious adverse events, and all-cause mortality. The majority of the adverse events seem to be non-serious and tolerable. There was an observed non-significant lower risk of serious adverse events, cardiac disorders, and significantly reduced risk of major adverse cardiovascular events when compared to placebo. Inclisiran was also linked to a significant decline in the percentage of LDL-C, PCSK9, total cholesterol, and Apo B in patients with hyperlipidemia. With the evidence available at present, inclisiran seems an efficacious and well-tolerated therapeutic strategy to manage elevated cholesterol and LDL-C levels. However, long-term, large cardiovascular outcome trials are required to conclude on the drug's cardiovascular and overall safety.

Microvascular changes on nailfold capillaroscopy in acute stage of Kawasaki disease: a new diagnostic paradigm for an enigmatic condition.

OBJECTIVES: Kawasaki disease (KD) is a medium vessel vasculitis with a predilection to involve coronary arteries. However, there is a paucity of literature on microvascular changes in patients with KD. METHODS: Children diagnosed with KD based on American Heart Association guidelines 2017 were enrolled prospectively. Demographic details and echocardiographic changes in coronaries were recorded. Nailfold capillaries were assessed using Optilia Video capillaroscopy and data were analysed using Optilia Optiflix Capillaroscopy software at acute (prior to IVIG administration) and subacute/convalescent phase. RESULTS: We enrolled 32 children with KD (17 boys) with a median age of 3 years. Nailfold capillaroscopy (NFC) was performed in 32 patients in the acute phase (compared with 32 controls) and in 17 during the subacute/convalescent phase at a median follow-up of 15 (15-90) days after IVIG treatment. The following findings were seen in NFC in the acute phase of KD: reduced capillary density (n = 12, 38.6%), dilated capillaries (n = 3, 9.3%), ramifications (n = 3, 9.3%) and capillary haemorrhages (n = 2, 6.2%). Capillary density was reduced significantly in the acute phase of KD (38.6%) as compared with the subacute/convalescent phase (25.4%) (P-value <0.001) and controls (0%) (P-value = 0.03). We observed no correlation between coronary artery involvement and mean capillary density (P = 0.870). CONCLUSION: Results show that patients with KD have significant nailfold capillary changes in the acute phase. These findings may provide a new diagnostic paradigm for KD and a window to predict coronary artery abnormalities.

Protocolized Sedation Utilizing COMFORT-B Scale versus Non-protocol-directed Sedation in Mechanically Ventilated Children - An Open-label, Randomized Controlled Trial.

This study aimed to determine the effect of protocolized sedation using the COMFORT-B scale on the duration of mechanical ventilation (DMV). Eighty children with anticipated Duration of mechanical ventilation (DMV) >24 h admitted to the Pediatric intensive care unit (PICU) were randomized into one group that received protocolized sedation (PS) using the COMFORT behavioural (COMFORT-B) scale, and another group that received non-protocolized sedation (NPS). The primary outcome was the impact on the DMV. The DMV was significantly lower in PS (PS: 3.5 [3-7] vs. NPS group: 8.5 [4.25-13.75] d; p = 0.008). The cumulative dose and duration of fentanyl in the PS group was significantly lower (median [IQR]; 120 [62.88-279.12] vs. 320.4 [110.88-851.52] µg/kg; p = 0.007 and 4 [2.25-7.75] vs. 8 [4-17.5] d; p = 0.009, respectively). The authors found a decrease in DMV and sedation related adverse events (SRAE) like ventilator associated pneumonia (VAP), accidental extubation, post-extubation stridor and dose and duration of sedative agents with PS.

Delays in diagnosis is the commonest proximate reason for mortality in hereditary angioedema: our experience at Chandigarh, India.

BACKGROUND: Hereditary angioedema (HAE) is a rare autosomal dominant disorder characterized clinically by recurrent episodes of non-pruritic subcutaneous and/or submucosal edema. Laryngeal edema is the commonest cause of mortality in patients with HAE. Prior to the availability of first-line treatment options for management of HAE, the mortality used to be as high as 30%. The mortality has significantly reduced in countries where first-line treatment options are available and patients can access these therapies. There is paucity of literature on the outcomes of patients with HAE in developing countries where availability and access to first-line treatment options is still a challenge. OBJECTIVE: To report our experience with mortality in patients with HAE and to report factors associated with death of these patients. METHODS: We carried out a record review of all patients diagnosed to have HAE between January 1996 and August 2022. Families with HAE who had reported death of at least one family member/relative because of laryngeal edema were studied in detail. RESULTS: Of the sixty-five families (one hundred and seventy patients) registered in the clinic, sixteen families reported death of at least one family member/relative because of laryngeal edema (total thirty-six deaths). Of these sixteen families, fourteen families reported that one or more family members had experienced at least one attack of laryngeal edema. One patient died during follow-up when she was taking long-term prophylaxis with stanozolol and tranexamic acid while remaining thirty-five patients were not diagnosed to have HAE at the time of their death. At the time of death of all thirty-six patients, at least one other family member had symptoms suggestive of HAE but the diagnosis was not established for the family. CONCLUSIONS: This is the largest single centre cohort of patients with HAE in India reporting mortality data and factors associated with death in these families. Delay in diagnosis is the commonest reason for mortality.

Safety and Efficacy of Resveratrol in Healing of Maxillofacial Fractures: A Randomized Controlled Study.

Objectives: To assess the efficacy of resveratrol in improving functional outcomes following open reduction and internal fixation of maxillofacial fractures. Study Design: A single-center, randomized, parallel group, prospective, double-blind clinical trial was conducted on 40 patients between the age 20 and 60 years, requiring open reduction and internal fixation of maxillofacial fractures. The selected patients were randomly divided into two groups, Group 1 (placebo) and Group 2 (resveratrol) where tablets resveratrol 500 mg were given twice daily for 1 month following open reduction and internal fixation of fractured segments. Bite force was calculated pre-operatively and on the 1st, 4th, 8th and 12th week postoperatively. Serum markers osteocalcin and alkaline phosphate were calculated pre-operatively and at 4th and 12th week postoperatively. Results: Bite force (690.55 ± 262.00) in the resveratrol group was higher than the placebo group (553.27 ± 300.08) at 12th week postoperatively. However, the difference was non-significant statistically (p = 0.132). Resveratrol group (116.80 ± 55.25) showed better maintenance of serum ALP level as compared to placebo group (107.90 ± 42.99) at 12th week postoperatively, but again it lacked statistical significance (p = 0.573). Resveratrol group after initial reduction at 4th week showed serum osteocalcin levels nearly equal to the preoperative values at 12th week, while the placebo group showed a decline both at 4th and 12th week postoperatively. However, these results were not statistically significant (p = 0.065). Conclusion: There was no statistically significant difference in bite force, serum ALP level and serum osteocalcin levels between placebo group and resveratrol group. Though not statistically significant but early increased level of serum osteogenic markers, better restoration of bite force in group 2 (tab. Resveratrol) indicates toward its possible optimistic role in maxillofacial fracture healing. More studies with larger sample sizes are needed in order to confirm the efficacy of this drug in maxillofacial fracture.

COVISHIELD vaccine-induced thyroiditis: a case report.

BACKGROUND: The rapid development of coronavirus disease 2019 vaccines during the pandemic has left their long-term effects largely unknown. Instances of autoimmune and subacute thyroiditis showing features of autoimmune/inflammatory syndrome induced by adjuvants have been reported post-vaccination. This case report aims to highlight the autoimmune/inflammatory syndrome induced by adjuvants syndrome after coronavirus disease 2019 vaccination, drawing attention to a possible connection with thyroid dysfunction and urging for further thorough research. CASE PRESENTATION: We present a case of thyroiditis induced by the COVISHIELD vaccine in a 37-year-old Indian woman. An apparently normal and healthy adult woman developed neck pain and easy fatigability 2 weeks after the second dose of COVISHIELD, which gradually increased and was associated with irritability, decreased sleep, excessive sweating, tremor, palpitation, and weight loss. She presented to the outpatient department after 1 week of symptoms and was evaluated with laboratory tests and imaging. She was diagnosed with thyroiditis due to the coronavirus disease 2019 vaccine and was treated with propranolol. CONCLUSION: This case report adds to the growing evidence of coronavirus disease 2019 vaccine-related thyroid issues. The development of thyroiditis is rare and underreported post-coronavirus disease 2019 vaccination; hence, research to evaluate the association of coronavirus disease 2019 vaccines with thyroid dysfunction needs to be done in the future.
