Autologous stem cell boost improves persistent immune effector cell associated hematotoxicity following BCMA directed chimeric antigen receptor T (CAR T) cell therapy in multiple myeloma.

Persistent Immune Effector Cell Associated Hematotoxicity (ICAHT) is a significant side effect of BCMA CAR T-Cell therapy in patients with relapsed multiple myeloma (MM). The use of stem cell boosts in ICAHT has been described, however studies have been limited by small patient numbers and short follow up. Herein, we report on our multi-institutional experience of ICAHT, defined by an absolute neutrophil count (ANC) of ≤ 1000, thrombocytopenia with a platelet count ≤ 50,000 or/and anemia as hemoglobin (hgb) ≤9 g/dL, in patients who received BCMA CAR T therapy, and the effects of subsequent stem cell boost on hematopoietic reconstitution and clinical outcome. In this study, ICAHT was observed in 60% (n = 61/101) of patients at D + 21, and risk factors for its development included history of a prior ASCT, higher number of prior lines of therapy, a decreased platelet count prior to lymphodepletion and history of ICANS. 28% of patients with ICAHT received a stem cell boost at a median of 116 days due to profound and prolonged cytopenias often requiring ongoing transfusion support. Stem cell boost significantly improved cytopenias at 3 and 6 months follow up without any adverse effects on PFS and OS, underscoring the safety of this procedure.

Amyloid Light-Chain (AL) Amyloidosis of the Trachea Associated With an Indolent B-cell Neoplasm.

We report the case of a 66-year-old woman who was diagnosed with localized tracheal amyloid light-chain (AL) amyloidosis caused by an underlying B-cell neoplasm. The diagnosis was confirmed through subsequent bronchoscopy and biopsies; however, she experienced a challenging episode of hypoxic respiratory failure that required intervention. Repeat bronchoscopies showed persistent subglottic stenosis and tracheobronchomalacia, which led to tracheal debulking surgery and additional interventions. The patient's treatment began with rituximab, zanubrutinib, and dexamethasone with outpatient follow-up. The rarity of tracheobronchial amyloidosis and its connection to B-cell malignancies are highlighted, emphasizing the challenges in diagnosis and the importance of tailored treatment strategies. The patient's clinical course, characterized by atypical respiratory symptoms, delayed diagnosis, and an evolving treatment approach, underscores the complexities of managing such a rare and intricate case.

Impact of elexacaftor/tezacaftor/ivacaftor on lipid and fat-soluble vitamin levels and association with body mass index.

INTRODUCTION: Cystic fibrosis transmembrane conductance regulator (CFTR) modulators improve gastrointestinal absorption of nutrients and may result in changes in body mass index (BMI), serum lipids, and fat-soluble vitamin levels. We hypothesized that serum lipids and vitamin levels would increase with CFTR modulator therapy and that greater increase in lipids and vitamin levels would be related to greater increase in BMI. METHODS: A retrospective study was performed to evaluate the impact of elexacaftor/tezacaftor/ivacaftor (ETI) on nutritional parameters, serum lipids, and fat-soluble vitamin levels. Pre-ETI values (<2 years prior) and post-ETI values (>1 month after) were compared. Linear regression was used to evaluate whether change in BMI is associated with the change in lipid and/or vitamin levels and whether modulator duration is associated with the degree of rise in lipid and/or vitamin levels. RESULTS: Adults and adolescents with CF (n = 137) were evaluated before and 31-300 days after starting ETI. Median BMI (adults 21.9 vs. 23.5 kg/m2 ; adolescents 48 vs. 63 percentile) increased after initiation of ETI. Total cholesterol (126 vs. 154 mg/dL), low-density lipoprotein cholesterol (63 vs. 78 mg/dL), non-high-density lipoprotein cholesterol (84 vs. 102 mg/dL), and high density lipoprotein cholesterol (43 vs. 49 mg/dL) increased after ETI, while triglycerides and very low density lipoprotein did not change. Median values for vitamin D (34.5 vs. 38.0 ng/mL) and vitamin A (40.1 vs. 47.9 µg/dL) increased, while vitamin E did not change significantly. There was no significant correlation between BMI change or duration of modulator therapy with vitamin levels or lipid changes. CONCLUSION: After initiation of ETI therapy, serum lipids increased in our population, but most values remained within the normal range. Vitamins A and D levels increased post-ETI and no changes were noted in vitamin E. No significant correlation between the degree of BMI change and the magnitude of increase in lipids or vitamin levels was found.

Necrotizing Enterocolitis in a Patient With Newly Diagnosed Multiple Myeloma and Hyperviscosity Syndrome: A Case Report.

Multiple myeloma (MM) is a clonal plasma cell proliferative disorder characterized by the abnormal increase of monoclonal paraprotein and can lead to specific end-organ damage. Necrotizing enterocolitis or bowel necrosis is a surgical emergency defined by cellular death because of reduced blood flow to the gastrointestinal tract. We report a case of a 75-year-old female who was diagnosed with hyperviscosity syndrome (HVS) and was sent to ED. Further workup showed that she had a new diagnosis of IgG kappa MM for which she was started on chemotherapy. Later, she developed respiratory distress and abdomen distention with less frequent bowel movements, and general surgery was consulted. CT scan of the abdomen and pelvis with contrast showed findings consistent with bowel ischemia vs infarction. The patient was immediately taken to the operating room, and exploratory laparotomy showed nonsurvivable bowel necrosis. She was transitioned to comfort care and passed away later. We aim to increase awareness among physicians to include HVS as one of the possible complications of MM and to detect it early to prevent morbidity and mortality.

A common neural code for meaning in discourse production and comprehension.

How does the brain code the meanings conveyed by language? Neuroimaging studies have investigated this by linking neural activity patterns during discourse comprehension to semantic models of language content. Here, we applied this approach to the production of discourse for the first time. Participants underwent fMRI while producing and listening to discourse on a range of topics. We used a distributional semantic model to quantify the similarity between different speech passages and identified where similarity in neural activity was predicted by semantic similarity. When people produced discourse, speech on similar topics elicited similar activation patterns in a widely distributed and bilateral brain network. This network was overlapping with, but more extensive than, the regions that showed similarity effects during comprehension. Critically, cross-task neural similarities between comprehension and production were also predicted by similarities in semantic content. This result suggests that discourse semantics engages a common neural code that is shared between comprehension and production. Effects of semantic similarity were bilateral in all three RSA analyses, even while univariate activation contrasts in the same data indicated left-lateralised BOLD responses. This indicates that right-hemisphere regions encode semantic properties even when they are not activated above baseline. We suggest that right-hemisphere regions play a supporting role in processing the meaning of discourse during both comprehension and production.

Sixth Nerve Palsy From Multiple Myeloma in Central Nervous System: Case Series and Review of Current Literature.

We reported two cases of the central nervous system (CNS) multiple myeloma (MM) with unusual presentation of sixth nerve palsy. The first patient developed in the setting of newly diagnosed MM and the second patient in the relapsed refractory setting. One underwent surgery, and the other received radiation. Both patients received systemic chemotherapy and noted improvement. We also performed a comprehensive literature review of previously published cases of sixth nerve palsy from MM. This review highlights the importance of recognizing this presentation of CNS multiple myeloma to avoid delays in diagnosis and to get appropriate management in time.

A Quinquennial Review on Recent Advancements and Developments in Search of Anti-malarial Agents.

Malaria has been a major parasitic disease in tropical and subtropical regions and is estimated to kill between one and two million people (mainly children) every year. Novel anti-malarial agents are urgently needed to combat the malarial parasites enduring resistance to the current medications, leading to increased morbidity and mortality. The heterocycles, holding a prominent position in chemistry and found in both natural and synthetic sources, have shown several biological activities including anti-malarial activity. Towards this goal, several research groups have reported the design and development of novel and potential anti-malarial agents like artemisinin, benzimidazole, benzothiazole, chalcone, cyclopeptide, fosmidomycin, furan, indole oxadiazole, 2-oxindoles, peroxides, pyrazole, pyrazolines, pyridines, pyrimidine, pyrrolidine, quinazoline, quinazolinone, quinolone, quinoline, thiazole, triazole and other scaffolds acting against newly emerging anti-malarial targets. The present work reports the complete quinquennial coverage of anti-malarial agents reported during 2016-2020 with a view of providing the merits and demerits of reported anti-malarial scaffolds, structure-activity relationship, along with their in vitro/ in vivo/ in silico profiles to the medicinal chemists working in the field of design and discovery of novel anti-malarial agents.

Modulation of brain activity by psycholinguistic information during naturalistic speech comprehension and production.

Language processing requires the integration of diverse sources of information across multiple levels of processing. A range of psycholinguistic properties have been documented in previous studies as having influence on brain activation during language processing. However, most of those studies have used factorial designs to probe the effect of one or two individual properties using highly controlled stimuli and experimental paradigms. Little is known about the neural correlates of psycholinguistic properties in more naturalistic discourse, especially during language production. The aim of our study is to explore the above issues in a rich fMRI dataset in which participants both listened to recorded passages of discourse and produced their own narrative discourse in response to prompts. Specifically, we measured 13 psycholinguistic properties of the discourse comprehended or produced by the participants, and we used principal components analysis (PCA) to address covariation in these properties and extract a smaller set of latent language characteristics. These latent components indexed vocabulary complexity, sensory-motor and emotional language content, discourse coherence and speech quantity. A parametric approach was adopted to study the effects of these psycholinguistic variables on brain activation during comprehension and production. We found that the pattern of effects across the cortex was somewhat convergent across comprehension and production. However, the degree of convergence varied across language properties, being strongest for the component indexing sensory-motor language content. We report the full, unthresholded effect maps for each psycholinguistic variable, as well as mapping how these effects change along a large-scale cortical gradient of brain function. We believe that our findings provide a valuable starting point for future, confirmatory studies of discourse processing.

Acute Disseminated Encephalomyelitis (ADEM) After Consecutive Exposures to Mycoplasma and COVID Vaccine: A Case Report.

Acute disseminated encephalomyelitis (ADEM) is an autoimmune demyelinating disease of the central nervous system, commonly triggered by viral infections or after immunization. ADEM occurrences in adults are rare. Full spectrum of complications is unknown for novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mRNA vaccines. A previously healthy 44-year-old female presented to the emergency room (ER) with acute onset of tingling, numbness, and weakness of both lower extremities, urinary retention, blurred vision in right eye, and midline lower back pain. Physical examination revealed bilateral lower extremity weakness 1/5, absent deep tendon reflexes, and decreased sensation. She received the first dose of SARS-CoV-2 vaccine six days prior to presentation to ER. Imaging of her lumbar spine and head were consistent with an active demyelinating plaque consistent with demyelinating disease either multiple sclerosis (MS) or ADEM. The patient was started on SoluMedrol 500 mg IV twice daily for five days. Serological workup and CSF analysis were nonsignificant except for Mycoplasma pneumonia IgM, elevated myelin basic protein, and positive IgG, IgA, and IgM. Patient gradually improved and was transferred to rehabilitation. Repeat MRI brain and spine showed improvement in previous lesions. However, she had worsening left eye symptoms that prompted her transfer to another facility for plasmapheresis. Plasma exchange was done for five treatments for ADEM. Patient started noticing improvement in vision and was discharged on steroid taper. We report a case of a possible association between ADEM and SARS-CoV-2 mRNA vaccine. It should be considered in the differential diagnosis in any case suggestive of acute demyelination after COVID-19 vaccination.

Calciphylaxis in End-Stage Renal Disease: A Rare Condition With High Mortality.

Calciphylaxis is a rare but life-threatening condition, seen in patients with end-stage renal disease (ESRD) on renal replacement therapy. Its pathogenesis is not completely known, but microvascular calcification and thrombosis are considered the likely processes. It is characterized by significant morbidity due to severe pain and nonhealing wounds with frequent hospitalizations. Sepsis is the most common cause of mortality with more than 50% of patients dying within the first year after diagnosis. Optimal management requires a multidisciplinary approach. We describe a case of a 66-year-old female with ESRD on hemodialysis (HD) who presented with severe progressive calciphylaxis wounds on both lower extremities and died within two months after diagnosis. She had multiple admissions in the past for cellulitis when she presented with swelling in the legs and chronic wounds. Our goal is to increase awareness among physicians to include calciphylaxis in their differential diagnosis when treating ESRD patients with significant risk factors to detect it early and prevent morbidity and mortality.

Emerging Pathophysiological Mechanisms Linking Diabetes Mellitus and Alzheimer's Disease: An Old Wine in a New Bottle.

Type-2 diabetes mellitus (T2DM) is a chronic immuno-inflammatory and metabolic disease characterized by hyperglycemia and insulin resistance with corresponding hyperinsulinemia. On the other hand, Alzheimer's disease (AD) is a neurodegenerative disease involving cognitive impairment, neuronal dysfunction, and memory loss. Several recently published literatures suggest a causal relationship between T2DM and AD. In this review, we have discussed several potential mechanisms underlying diabetes-induced cognitive impairment which include, abnormal insulin signaling, amyloid-ß accumulation, oxidative stress, immuno-inflammation, mitochondrial dysfunction, advanced glycation end products, acetylcholinesterase and butyrylcholinesterase, advanced lipid peroxidation products, and apolipoprotein E. All these interconnected mechanisms may act either individually or synergistically which eventually leads to neurodegeneration and AD.

Meta-Analysis of APP Expression Modulated by SARS-CoV-2 Infection via the ACE2 Receptor.

Alzheimer's disease (AD) is characterized by the deposition of amyloid-beta (Aß) plaques from improper amyloid-beta precursor protein (APP) cleavage. Following studies of inflammation caused by coronavirus-2019 (COVID-19) infection, this study investigated the impact of COVID-19 on APP expression. A meta-analysis was conducted utilizing QIAGEN Ingenuity Pathway Analysis (IPA) to examine the link between severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) and the modulation of APP expression upon virus binding the Angiotensin-converting enzyme-2 (ACE2) receptor. A Core Analysis was run on the infection by severe acute respiratory syndrome (SARS) coronavirus node, which included molecules affected by SARS-CoV-2, revealing its upstream regulators. Intermediary molecules were found between the upstream regulators and ACE2 and between ACE2 and APP. Activation of the upstream regulators downregulated the expression of ACE2 with a Z-score of -1.719 (p-value = 0.086) and upregulated APP with a Z-score of 1.898 (p-value = 0.058), showing a less than 10% chance of the results occurring by chance and pointing to an inverse relationship between ACE2 and APP expression. The neuroinflammation signaling pathway was the fifth top canonical pathway involved in APP upregulation. The study results suggest that ACE2 could be downregulated by SARS-CoV-2, resulting in APP upregulation, and potentially exacerbating the onset and progression of AD.

Similar neural networks respond to coherence during comprehension and production of discourse.

When comprehending discourse, listeners engage default-mode regions associated with integrative semantic processing to construct a situation model of its content. We investigated how similar networks are engaged when we produce, as well as comprehend, discourse. During functional magnetic resonance imaging, participants spoke about a series of specific topics and listened to discourse on other topics. We tested how activation was predicted by natural fluctuations in the global coherence of the discourse, that is, the degree to which utterances conformed to the expected topic. The neural correlates of coherence were similar across speaking and listening, particularly in default-mode regions. This network showed greater activation when less coherent speech was heard or produced, reflecting updating of mental representations when discourse did not conform to the expected topic. In contrast, regions that exert control over semantic activation showed task-specific effects, correlating negatively with coherence during listening but not during production. Participants who showed greater activation in left inferior prefrontal cortex also produced more coherent discourse, suggesting a specific role for this region in goal-directed regulation of speech content. Results suggest strong correspondence of discourse representations during speaking and listening. However, they indicate that the semantic control network plays different roles in comprehension and production.

A review on synthetic account of 1,2,4-oxadiazoles as anti-infective agents.

Most of the currently marketed drugs consist of heterocyclic scaffolds containing nitrogen and or oxygen as heteroatoms in their structures. Several research groups have synthesized diversely substituted 1,2,4-oxadiazoles as anti-infective agents having anti-bacterial, anti-viral, anti-leishmanial, etc. activities. For the first time, the present review article will provide the coverage of synthetic account of 1,2,4-oxadiazoles as anti-infective agents along with their potential for SAR, activity potential, promising target for mode of action. The efforts have been made to provide the chemical intuitions to the reader to design new chemical entity with potential of anti-infective activity. This review will mark the impact as the valuable, comprehensive and pioneered work along with the library of synthetic strategies for the organic and medicinal chemists for further refinement of 1,2,4-oxadiazole as anti-infective agents.

Cerebral Venous Thrombosis Presenting as a Subacute Headache in a Young Man With Undiagnosed Factor V Leiden Mutation.

Cerebral venous sinus thrombosis (CVT) is a rare but potentially life-threatening condition that presents with non-specific symptoms. This condition is more common in women and can be associated with local infection and hypercoagulable conditions, including protein C and S deficiency, factor V Leiden mutation, anti-thrombin III deficiency, thrombophilia, vasculitis, and malignancy. We report the case of a 24-year-old man who presented with a left temporal headache and right upper and lower extremity paresthesia. He also experienced impaired vision (altered spatial sensation), dental pain, bruxism, nausea, and vomiting. Magnetic resonance imaging and magnetic resonance venography of the brain revealed widespread thrombosis of the cerebral sinuses as well as left superior cerebral cortical veins bilaterally. No evidence of venous infarct was found. Subsequent hematologic evaluation showed the presence of heterozygous factor V Leiden mutation. Testing of family members subsequently revealed the presence of this same mutation in his mother and all three siblings, although there was no family history of stroke, hypercoagulability, or atypical headaches. The patient was started on low-molecular-weight heparin and later transitioned to apixaban. Progression of his headache and visual abnormalities led to the discovery of increased intracranial pressure as demonstrated by papilledema and characteristic findings on computed tomography scan. He was treated with acetazolamide with improvement of his symptoms. CVT is uncommon and can be a diagnostic challenge due to its atypical presentation. Clinicians should consider this diagnosis in patients with a subacute onset of atypical headache, especially when accompanied by seizures, focal neurological deficits, or altered consciousness.

Choroidal Metastasis as the Initial Presentation of Rectal Adenocarcinoma.

Choroidal metastasis from rectal cancer is a rare occurrence with limited literature on appropriate evidence-based treatment options. We describe the case of 44-year-old man who presented with left-sided painful vision loss who was found to have left choroidal and multiple lung metastasis from an unknown primary which was later found to be rectal adenocarcinoma. LEARNING POINTS: Ocular metastasis from colorectal cancer is rare with choroid being the most common site of involvement if it occurs.Ocular metastasis usually occurs as a part of generalized metastasis to multiple organ systems.Treatment options include systemic chemotherapy, radiation, bevacizumab and enucleation.

IgE and eosinophils as therapeutic targets in asthma.

PURPOSE OF REVIEW: Asthma is a chronic inflammatory disorder characterized by reversible airflow obstruction, which is being more widely recognized as a broad-spectrum disease that encompasses multiple patient characteristics and pathophysiologic mechanisms. Suboptimal asthma control leads to increasing burden of healthcare costs and loss of productivity to society. Biologic therapies targeted at IgE and eosinophils can be used in poorly controlled allergic and eosinophilic asthma, respectively. The purpose of this review is to analyze the advancements in currently available biologic therapies targeted at IgE and eosinophils in asthma and to identify how these therapies may impact overall healthcare costs. RECENT FINDINGS: Omalizumab is an anti-IgE antibody that is approved for use of poorly controlled moderate-to-severe asthma. Many studies have confirmed that omalizumab not only improves quality of life and symptom scores, but also decreases urgent care and emergency department visits and hospitalizations. Dupilumab is a biologic agent targeted at TH2 cytokines, but indirectly impacts IgE and is an important biologic agent for atopic disease. Mepolizumab, reslizumab, and benralizumab target IL-5, a key cytokine for eosinophils. For patients with poorly controlled eosinophilic asthma, these biologic agents improve asthma symptoms, reduce exacerbations, and reduce emergency visits and hospitalizations. SUMMARY: Poorly controlled severe asthma affects a small portion of patients with asthma in the United States and yet it accounts for large portion of healthcare utilization. Biological therapies in poorly controlled severe persistent asthma have been identified to reduce healthcare utilization, including emergency visits and hospitalizations. Biologic agents have a clear beneficial role in the management of severe asthma, and further evaluations should be continued in identifying optimal patient characteristics for the various agents and overall benefit toward healthcare utilization and cost.

Chemical Shift MR Imaging of the Adrenal Gland: Principles, Pitfalls, and Applications.

Adrenal lesions are a common imaging finding. The vast majority of adrenal lesions are adenomas, which contain intracytoplasmic (microscopic) fat. It is important to distinguish between adenomas and malignant tumors, and chemical shift magnetic resonance (MR) imaging can be used to accomplish this distinction by depicting the fat in adenomas. Chemical shift imaging is based on the difference in precession frequencies of water and fat molecules, which causes them to be in different relative phases during the acquisition sequence and allows in-phase and opposed-phase images to be obtained. It is important to acquire these images by using the earliest possible echo times, with the opposed-phase echo before the in-phase echo, and by using a single breath hold to preserve diagnostic accuracy. Intracytoplasmic fat is depicted as signal drop on opposed-phase images when compared with in-phase images. Both qualitative and quantitative methods for assessing signal drop are detailed. The appearances of adrenal adenomas and other adrenal tumors on chemical shift MR images are described, and discriminatory ability at chemical shift MR imaging compared with that at adrenal computed tomography (CT) is explained. Other adrenal-related conditions in which chemical shift MR imaging is helpful are also discussed. Chemical shift MR imaging is a robust tool for evaluating adrenal lesions that are indeterminate at nonenhanced CT. However, it is important to know the advantages and disadvantages, including several potential imaging pitfalls. The characterization of adrenal lesions by using chemical shift MR imaging and adrenal CT should always occur in the appropriate clinical setting.

Release of cytokines in stored whole blood and red cell concentrate: Effect of leukoreduction.

BACKGROUND: Storage time of blood components plays a major role in the accumulation of cytokines causing adverse transfusion reactions. AIMS: The aim was to study the trend in the levels of interleukin-6 (IL-6), IL-8, tumor necrosis factor-alpha (TNF-α) and regulated upon activation, normal T-cells expressed and secreted (RANTES) during storage of whole blood (WB) and red cell concentrate (RCC) and to study the effect of leukoreduction (LR). MATERIALS AND METHODS: WB sample was taken on 0, 7, 14, 21, and between 28 and 35 days and plasma aliquots were frozen. Samples from RCC and buffy-coat depleted RCC prepared using Optipress II were collected on 0, 7, 14, 21 and between 28 and 35 days. Cytokine estimation was done using ELISA development kits. Normal range of cytokines was established using 0 day samples of WB. Statistical analysis was done using nonparametric tests. RESULTS AND CONCLUSION: The normal range of IL-6 was 0-23 pg/ml, IL-8 0-12 pg/ml, TNF-α 0-3 pg/ml, and RANTES 1200-2000 pg/ml. IL-6 was in normal range and showed a decreasing trend during storage. IL-8 levels increased significantly from 0 to 35 days. In RCC, the highest level was 480 pg/ml on 28(th) day. It was in the normal range in buffy-coat depleted RCC up to 28 days. RANTES level was significantly low in buffy-coat depleted RCC compared to RCC. We conclude that WB has high levels of IL-8 and RANTES. The levels of cytokines are affected by storage period and LR. Comparison of WB and buffy-coat depleted RCC shows significantly low levels of IL-6, IL-8, and RANTES in buffy-coat depleted RCC. This study emphasizes the use of red cell components instead of WB and buffy-coat depleted RCC instead of RCC.

Time Dependent Release of Interleukin-8 and Tumor Necrosis Factor-α in Platelet Concentrate.

Contaminating white blood cells in stored platelet concentrate (PC) are the source of many pro-inflammatory cytokines. These are implicated in transfusion reactions. To study the release of interleukin (IL)-8 and tumor necrosis factor alpha (TNF-α) at different time interval in PC prepared by-platelet rich plasma (PRP) and buffy coat (BC) using different principles. Fifteen PCs were prepared by both the methods. The supernatants of PCs prepared by PRP and BC methods were collected aseptically after 1, 18, 65 and 112 h of preparation. pH, platelet and WBC counts were done. The supernatants were frozen in aliquots at -56 °C for measurement of IL-8 and TNF-α concentration using ELISA. The Mean ± SD value of WBC in PRP-PC was 7.4 ± 3.75 × 10(7) and in BC-PC 3.9 ± 2.2 × 10(7). The mean platelet counts were 6.05 ± 1.94 × 10(10) and 6.54 ± 2.18 × 10(10) respectively. The highest level of IL-8 in one hour was up to 30 pg/ml in both the type of PC. It increased up to 986 pg/ml in PRP-PC and 481 pg/ml in BC-PC at 112 h. IL-8 increased significantly during storage period of 5 days in both types of PCs (P0.000 and P0.01). TNF-α level remained low up to 18 h. The highest level was 72 pg/ml in PRP-PC and 57 pg/ml in BC-PC at 65 h. IL-8 levels significantly increased after one hour of storage and TNF-α. levels were low up to 18 h and then showed increase. The BC-PC had significantly low levels of IL-8 compared to PRP-PC (P0.0001).
