Introduction

Sickle Cell Disease: A National Priority and Public Health Burden
Sickle Cell Disease (SCD) is an autosomal recessive hemoglobinopathy caused by a single point mutation (Glu6Val) in the beta-globin gene, resulting in the production of abnormal hemoglobin S (HbS). Under conditions of deoxygenation, HbS polymerises, distorting erythrocytes into a rigid sickle morphology. This seemingly simple molecular event triggers a devastating cascade of haemolytic anaemia, recurrent vaso-occlusive crises (VOC), progressive end-organ damage, and premature mortality [1].
Globally, approximately 300,000 children are born with SCD each year, with the highest burden concentrated in Sub-Saharan Africa, the Middle East, and India [2,3]. India holds the third highest birth rate of SCD worldwide, after Nigeria and the Democratic Republic of Congo [3]. Crucially, SCD in India carries distinct epidemiological features: it disproportionately affects tribal communities across states including Chhattisgarh, Madhya Pradesh, Maharashtra, Odisha, and Gujarat, where heterozygous and homozygous prevalence in certain tribal populations ranges from 1 to 40% [4]. Recognising this burden, the Government of India launched the National Sickle Cell Anaemia Elimination Mission (2023), a targeted programme to eliminate SCD as a public health problem by 2047. This national commitment makes SCD research not merely academically relevant but a matter of direct policy and healthcare priority.
Vaso-Occlusive Crisis: Beyond Physical Obstruction
The vaso-occlusive crisis is the most common acute complication of SCD and the leading driver of hospitalisation, morbidity, and impaired quality of life. VOC was historically understood as a mechanical process - physical obstruction of the microvasculature by sickled erythrocytes. Contemporary evidence has fundamentally revised this view. VOC is now recognised as a multifactorial inflammatory and endovascular event, driven by the complex interplay between sickled erythrocytes, activated neutrophils, platelets, and inflamed endothelial cells [5]. Cell adhesion molecules including P-selectin (expressed on activated endothelial cells and platelets), E-selectin, and VCAM-1 orchestrate the capture and sequestration of sickle cells within the microvasculature. Intravascular haemolysis simultaneously liberates free haemoglobin and reactive oxygen species into circulation, which scavenge nitric oxide (NO), deplete plasma haptoglobin, and activate endothelin-mediated vasoconstriction [6]. The resulting ischemia-reperfusion injury further perpetuates endothelial activation, creating a self-sustaining vicious cycle of inflammation, vasoconstriction, and vascular obstruction [5,6].
Despite this detailed mechanistic understanding, reliable biomarkers that can objectively quantify the intensity of endovascular stress and cellular injury during VOC - and distinguish it from steady-state disease - remain elusive in clinical practice. This is a critical unmet need: such biomarkers could guide clinical decision-making, identify patients at high risk for organ damage, and serve as pharmacodynamic endpoints for emerging therapies.
Heat Shock Protein 90: A Molecular Chaperone at the Intersection of Stress and Vascular Biology
Heat Shock Protein 90 (HSP90) is a highly conserved, ATPase-dependent molecular chaperone that constitutes approximately 1-2% of total cellular protein under physiological conditions [7,8]. Its expression is markedly upregulated by cellular stressors including hypoxia, oxidative stress, heat shock, and ischaemia-reperfusion injury - precisely the biological milieu that defines an acute VOC episode [9]. HSP90 is not simply a stress responder; it is a master regulator of proteostasis, stabilising and activating a broad repertoire of client proteins involved in cell survival, signal transduction, apoptotic regulation, and vascular function [10,11].
Of particular vascular relevance is the well-characterised HSP90-endothelial nitric oxide synthase (eNOS) axis. Under homeostatic conditions, HSP90 forms a stable complex with eNOS, facilitating its activation and the consequent production of NO - a vasodilatory, anti-adhesive, and anti-inflammatory molecule that is fundamental to endothelial health [12]. During oxidative stress - as occurs during VOC - excess reactive oxygen species disrupt the HSP90-eNOS coupling, leading to eNOS uncoupling. Uncoupled eNOS shifts its enzymatic output from protective NO to pro-oxidant superoxide, further amplifying endothelial dysfunction, platelet activation, and the inflammatory cascade characteristic of SCD [13,14]. This mechanistic link positions HSP90 as a potentially pivotal molecular mediator of the transition from steady state to acute crisis in SCD.
The Knowledge Gap and Rationale for This Study
While HSP90 has been studied as a biomarker and therapeutic target in conditions characterised by cellular stress - including sepsis, ischaemia-reperfusion injury, and inflammatory diseases - its quantitative plasma levels in the context of SCD, and specifically during acute VOC versus steady state, remain unexplored. No published study to date has directly compared plasma HSP90 concentrations between these two clinical states in SCD patients, and data from Indian patients is entirely absent from the literature. This represents a significant gap, given that the molecular and inflammatory phenotype of SCD may differ between populations due to genetic modifiers, nutritional factors, and environmental stressors.
If plasma HSP90 levels are demonstrably elevated during VOC compared to steady state, this would provide preliminary evidence for its role as a stress-responsive endovascular biomarker in SCD. Furthermore, correlating HSP90 with established markers of haemolysis (LDH), inflammation (CRP), and organ function (LFT, RFT, CBC) would help contextualise its biological significance and potential clinical utility.
Research Question
Are plasma HSP90 levels significantly elevated during acute vaso-occlusive crisis compared to the steady state in adult HbSS patients, and do these levels correlate with established haematological and biochemical markers of disease activity?
Hypothesis
Plasma HSP90 levels are significantly higher during acute VOC compared to steady-state in adult HbSS patients, reflecting heightened cellular stress, oxidative injury, and eNOS uncoupling. Plasma HSP90 will show a positive correlation with markers of haemolysis and inflammation during VOC.
Brief Experimental Overview
To address this, a prospective paired observational study will be conducted at a tertiary sickle cell referral centre in Central India. Adult HbSS patients (n=40) will be enrolled during acute VOC, and each participant will serve as their own control at 3-week follow-up during steady state. Plasma HSP90 levels will be quantified by sandwich ELISA and correlated with simultaneous CBC, LDH, CRP, LFT, and RFT results. This paired design eliminates inter-individual genetic and environmental confounders, maximising statistical power to detect within-patient differences.

Introduction

Sickle Cell Disease: A National Priority
Sickle Cell Disease (SCD) is an autosomal recessive hemoglobinopathy caused by a Glu6Val point mutation in the beta-globin gene, producing abnormal hemoglobin S (HbS). Under deoxygenation, HbS polymerises, deforming erythrocytes into rigid sickle shapes and triggering haemolytic anaemia, recurrent vaso-occlusive crises (VOC), progressive end-organ damage, and premature mortality [1,2]. India bears the third highest global SCD birth rate, with prevalence reaching up to 40% in tribal communities across Chhattisgarh, Madhya Pradesh, Maharashtra, and Odisha [3,4]. The Government of India's National Sickle Cell Anaemia Elimination Mission (2023) underscores SCD as a direct national health priority, making research in this population both timely and policy-relevant.
Vaso-Occlusive Crisis: An Endovascular Inflammatory Event
VOC is the leading cause of hospitalisation in SCD. Beyond mechanical obstruction, VOC is driven by P-selectin-mediated adhesion of sickle erythrocytes to activated endothelium, neutrophil-platelet interactions, and intravascular haemolysis that depletes nitric oxide (NO) and generates reactive oxygen species, perpetuating a self-sustaining cycle of vasoconstriction, ischaemia-reperfusion injury, and systemic inflammation [5,6]. Reliable biomarkers that objectively quantify this endovascular stress during VOC versus steady state remain a critical unmet clinical need.
HSP90: A Stress-Responsive Vascular Mediator
Heat Shock Protein 90 (HSP90) is a conserved molecular chaperone constituting ~1-2% of total cellular protein, whose expression is markedly induced by hypoxia, oxidative stress, and ischaemia-reperfusion injury [7,8,9]. Physiologically, HSP90 couples with eNOS to sustain protective NO production. During VOC, oxidative stress uncouples HSP90 from eNOS, shifting enzymatic output toward pro-oxidant superoxide, amplifying endothelial dysfunction and the inflammatory cascade [13,14].
Knowledge Gap, Research Question and Hypothesis
No published study has directly quantified plasma HSP90 levels during VOC versus steady state in SCD, and Indian patient data is entirely absent. This study asks: Are plasma HSP90 levels significantly elevated during acute VOC compared to steady state in adult HbSS patients? We hypothesise that plasma HSP90 is significantly higher during VOC, reflecting heightened cellular stress and eNOS uncoupling, and will correlate positively with established markers of haemolysis and inflammation.

Introduction

Sickle Cell Disease (SCD) is an autosomal recessive hemoglobinopathy caused by a Glu6Val point mutation in the beta-globin gene, producing abnormal haemoglobin S (HbS). Under deoxygenation, HbS polymerises, deforming erythrocytes into rigid sickle shapes and triggering haemolytic anaemia, recurrent vaso-occlusive crises (VOC), and progressive end-organ damage [1,2]. India bears the third highest global SCD birth rate, with prevalence reaching up to 40% in tribal communities across Central and Western India [3,4]. The Government of India's National Sickle Cell Anaemia Elimination Mission (2023) underscores SCD as a direct national priority, making research in this population both timely and policy-relevant.
VOC is the leading cause of hospitalisation in SCD. It is now understood not merely as mechanical obstruction, but as a complex endovascular inflammatory event driven by P-selectin-mediated adhesion of sickle erythrocytes to activated endothelium, neutrophil-platelet interactions, and intravascular haemolysis that depletes nitric oxide (NO) and generates reactive oxygen species, perpetuating ischaemia-reperfusion injury and systemic inflammation [5,6]. Despite this mechanistic understanding, objective biomarkers capable of quantifying endovascular stress during VOC versus steady state remain a critical unmet need in clinical practice.
Heat Shock Protein 90 (HSP90) is a conserved molecular chaperone constituting ~1–2% of total cellular protein, markedly induced by hypoxia, oxidative stress, and ischaemia-reperfusion injury [7,8,9]. Under physiological conditions, HSP90 couples with eNOS to sustain protective NO production, inhibiting adhesion and vasoconstriction. During VOC, oxidative stress uncouples this HSP90-eNOS complex, diverting enzymatic output toward pro-oxidant superoxide, amplifying endothelial dysfunction and the inflammatory cascade [13,14].
No published study has directly quantified plasma HSP90 levels during VOC versus steady state in SCD, and Indian patient data is entirely absent from literature. This study proposes to compare plasma HSP90 levels in adult HbSS patients during acute VOC and steady state using a paired design, correlating findings with CBC, LDH, CRP, LFT, and RFT, to evaluate HSP90 as a potential stress-responsive endovascular biomarker in SCD.

Under deoxygenation, HbS polymerises, deforming erythrocytes into rigid sickle shapes and triggering haemolytic anaemia, recurrent vaso-occlusive crises (VOC), and progressive end-organ damage [1,2].

The Government of India's National Sickle Cell Anaemia Elimination Mission (2023) has identified SCD as a direct national health priority, making research in this population both timely and policy-relevant.
Vaso-Occlusive Crisis: A Complex Endovascular Inflammatory Event
VOC is the leading cause of hospitalisation and morbidity in SCD. Beyond simple mechanical obstruction, VOC is now recognised as a multifactorial endovascular inflammatory process driven by P-selectin-mediated adhesion of sickle erythrocytes to activated endothelium, neutrophil-platelet interactions, and intravascular haemolysis that scavenges nitric oxide (NO) and generates reactive oxygen species (ROS), perpetuating ischaemia-reperfusion injury and systemic inflammation [5,6,7].

Physiologically, HSP90 forms a stable complex with endothelial nitric oxide synthase (eNOS), facilitating its activation and sustaining protective NO production, which inhibits platelet aggregation, leukocyte adhesion, and vasoconstriction [13]. During acute oxidative stress, ROS disrupt the HSP90-eNOS coupling, causing eNOS uncoupling and a shift toward pro-oxidant superoxide generation, directly amplifying endothelial dysfunction and the inflammatory cascade characteristic of VOC [14].
Knowledge Gap and Rationale
No published study to date has directly quantified and compared plasma HSP90 levels between acute VOC and steady state in SCD patients, and Indian-specific data is entirely absent from the literature. This study therefore aims to evaluate plasma HSP90 as a potential stress-responsive endovascular biomarker in adult HbSS patients using a prospective paired design, with each patient serving as their own control, correlating HSP90 with established parameters of haemolysis (LDH), inflammation (CRP), and organ function (CBC, LFT, RFT).

INTRODUCTION
Sickle Cell Disease: A Global Burden and India's National Priority
Sickle Cell Disease (SCD) is an autosomal recessive hemoglobinopathy arising from a single Glu6Val substitution in the beta-globin gene, producing abnormal haemoglobin S (HbS). Under deoxygenation, HbS polymerises into rigid fibres, distorting erythrocytes into sickle shapes and initiating a cascade of haemolytic anaemia, vaso-occlusive crises (VOC), and irreversible end-organ damage [1]. The Global Burden of Disease Study 2021 estimated over 8 million people living with SCD worldwide, with India accounting for the third highest birth prevalence globally [2]. Within India, the disease disproportionately affects tribal communities across Chhattisgarh, Madhya Pradesh, Maharashtra, and Odisha, with carrier rates reaching 40% in certain populations [3]. Recognising this burden, the Government of India launched the National Sickle Cell Anaemia Elimination Mission (2023), establishing SCD as a national healthcare priority and creating an urgent need for evidence-based research in the Indian patient population [3].
Vaso-Occlusive Crisis: An Inflammatory Endovascular Event
VOC is the hallmark complication of SCD and the primary driver of hospitalisation, chronic morbidity, and reduced quality of life. Contemporary evidence has redefined VOC as a multifactorial endovascular inflammatory process rather than simple mechanical obstruction. It is characterised by P-selectin-mediated adhesion of sickle erythrocytes to activated endothelium, a pro-inflammatory neutrophil-dominant leukocyte-erythrocyte interaction, and intravascular haemolysis that scavenges nitric oxide (NO), releases cell-free haemoglobin, and generates reactive oxygen species (ROS) - collectively perpetuating ischaemia-reperfusion injury, vasoconstriction, and a self-amplifying inflammatory cascade [4,5]. Despite this understanding, no validated, readily measurable plasma biomarker exists that reliably and objectively quantifies the degree of endovascular stress during VOC and distinguishes it from the steady state - a critical gap in clinical and research practice.
HSP90: A Mechanistically Justified Vascular Stress Biomarker
Heat Shock Protein 90 (HSP90) is a ubiquitous, ATP-dependent molecular chaperone comprising ~1–2% of total cellular protein under basal conditions [6]. Its expression is robustly induced by hypoxia, oxidative stress, and ischaemia-reperfusion injury [7] - the precise molecular environment of an acute VOC episode. Beyond its chaperone function, HSP90 plays a direct vascular role: it physically couples with endothelial nitric oxide synthase (eNOS), stabilising its active conformation and enabling sustained protective NO production [8]. During oxidative stress, excess ROS disrupt the HSP90-eNOS complex; uncoupled eNOS shifts enzymatic output from NO to pro-oxidant superoxide, amplifying endothelial dysfunction and perpetuating the inflammatory cascade central to VOC [9]. Circulating HSP90 has recently been identified as a measurable biomarker in systemic inflammatory and vascular disorders [10], lending biological plausibility to its evaluation in SCD.
Knowledge Gap and Study Rationale
No published study has directly quantified and compared plasma HSP90 levels during acute VOC versus steady state in SCD patients; Indian-specific data is entirely absent. This study proposes a prospective paired observational design in adult HbSS patients, where each participant serves as their own control, with plasma HSP90 measured by sandwich ELISA during VOC and at 3-week steady-state follow-up, correlated with CBC, LDH, CRP, LFT, and RFT - to evaluate HSP90 as a novel, mechanistically grounded endovascular biomarker in SCD.

No published study has directly quantified and compared plasma HSP90 levels during acute VOC versus steady state in SCD patients; Indian-specific data is entirely absent. This study proposes a prospective paired observational design in adult HbSS patients, where each participant serves as their own control, with plasma HSP90 measured by sandwich ELISA during VOC and at 3-week steady-state follow-up, correlated with CBC, LDH, CRP, LFT, and RFT - to evaluate HSP90 as a novel, mechanistically grounded endovascular biomarker in SCD.

INTRODUCTION
Sickle Cell Disease: A Global Burden and India's National Priority
Sickle Cell Disease (SCD) is an autosomal recessive hemoglobinopathy arising from a Glu6Val substitution in the beta-globin gene, producing abnormal haemoglobin S (HbS). Under deoxygenation, HbS polymerises, distorting erythrocytes into rigid sickle shapes and triggering haemolytic anaemia, recurrent vaso-occlusive crises (VOC), and progressive end-organ damage [1]. The Global Burden of Disease Study 2021 estimated over 8 million people living with SCD worldwide, with India accounting for the third highest birth prevalence globally [2]. Within India, the disease disproportionately affects tribal communities across Chhattisgarh, Madhya Pradesh, Maharashtra, and Odisha, with carrier rates reaching 40% in certain populations [3]. The Government of India's National Sickle Cell Anaemia Elimination Mission (2023) has established SCD as a national healthcare priority, creating an urgent need for evidence-based research in Indian patients [3].
Vaso-Occlusive Crisis: An Inflammatory Endovascular Event
VOC is the hallmark complication of SCD and the primary driver of hospitalisation and chronic morbidity. It is characterised by P-selectin-mediated adhesion of sickle erythrocytes to activated endothelium, neutrophil-dominated leukocyte-erythrocyte interactions, and intravascular haemolysis that scavenges nitric oxide (NO) and generates reactive oxygen species (ROS), perpetuating ischaemia-reperfusion injury and a self-amplifying inflammatory cascade [4,5]. No validated plasma biomarker currently exists to objectively quantify this endovascular stress and reliably distinguish VOC from steady state.
HSP90: A Mechanistically Justified Vascular Stress Biomarker
HSP90 is a ubiquitous molecular chaperone comprising ~1-2% of total cellular protein, robustly induced by hypoxia, oxidative stress, and ischaemia-reperfusion injury [6,7] - the precise molecular milieu of acute VOC. Physiologically, HSP90 couples with eNOS to sustain protective NO production [8]. During oxidative stress, ROS disrupt this complex, causing eNOS uncoupling and superoxide generation, amplifying endothelial dysfunction and inflammation [9]. Circulating HSP90 has recently been validated as a measurable systemic biomarker in vascular disease [10], directly supporting its evaluation in SCD.
Knowledge Gap and Study Rationale
No published study has directly quantified and compared plasma HSP90 levels during acute VOC versus steady state in SCD patients; Indian-specific data is entirely absent. This study proposes a prospective paired observational design in adult HbSS patients, where each participant serves as their own control, with plasma HSP90 measured by sandwich ELISA during VOC and at 3-week steady-state follow-up, correlated with CBC, LDH, CRP, LFT, and RFT - to evaluate HSP90 as a novel, mechanistically grounded endovascular biomarker in SCD.
