Prognostic value of serum amyloid A protein as a biomarker in the diagnosis of 2019 novel coronavirus disease (COVID-19)

BackgroundThe current study aimed to evaluate the prognostic value of serum amyloid A protein )SAA( protein as a biomarker in diagnosing 2019 novel coronavirus disease )COVID-19( infection. MethodsThe study was conducted on 123 patients with definitive COVID-19 infection referred to Shahid Beheshti and Sina hospitals in Hamedan province, Iran. Five-milliliter blood samples were taken from all included patients and serum was isolated using a centrifuge at 10,000 rpm for 10 minutes. Laboratory tests were conducted, including c-reactive protein (CRP), Erythrocyte Sedimentation Rate (ESR), potassium level, sodium blood test, platelets (PLT), complete blood count (CBC), lymphocyte count, and neutrophil count. The SAA enzyme-linked immunosorbent assay (ELISA) Kit was applied to measure the SAA level in serum samples. Results123 patients included 73 males and 50 females, age ±50. Sixty-six (53.7%) patients had negative CRP while 80 (65%) patients had normal ESR. Potassium levels were not normal among 111 (94.9%) patients. Seventy-seven (63.1%) patients had normal CBC, while 108 (87.8%) patients had neutrophils above the normal range. 94 (97.9%) patients over the age of 50 were positive for SAA. In terms of gender, men were the most frequent patients with SAA. There was a statistically significant relationship between the serum level of SAA and outcomes of patients with COVID-19 (p = 0.0001). 94% of patients with SAA ≤50 were recovered from COVID-19 infection. The sensitivity rate of SAA compared to polymerase chain reaction (PCR) and computed tomography scan (CT scan) tests was 93% and 99%, respectively. Moreover, the accuracy of SAA compared to PCR and CT scan tests was 52% and 96%, respectively. ConclusionResults indicate the SAA is a sensitive, but not specific biomarker in the early detection of COVID-19. The quantitative levels of SAA can be useful in predicting treatment outcomes among patients with COVID-19.

Comparative Study of Oral Naproxen and Aspirin for Acute Rheumatic Fever Treatment: Safety And Efficacy Analysis

Objectives: This observational case-control study aimed to assess the safety and efficacy of oral Naproxen as an alternative to oral Aspirin/acetylsalicylic acid (ASA) for treating acute rheumatic fever (ARF). Methodology: Patients meeting the revised Jones criteria 2015 for ARF were enrolled from November 2018 to May 2019 at a single tertiary care Children’s Hospital. They were divided into two groups: Group-A receiving ASA (control) and Group-B receiving Naproxen (case). Primary outcome measures included the number of days until complete resolution of arthralgia or arthritis, while secondary outcome measures included resolution of fever and normalization of erythrocyte sedimentation rate (ESR). Results: Sixty-four consecutive patients with ARF were enrolled, with 32 in each group, matched for age and gender. The majority (80%) had recurrent ARF. Median age at presentation was similar in both groups. ESR levels did not differ between the groups at admission or at the end of treatment. Median time for resolution of fever was 9(6-11) days in Group-A and 7.5(5-10) days in Group-B. Resolution time for arthritis was similar in both groups, with a median of 3(2-4) days. Gastric pain and vomiting were significantly lower in Group-B than in Group-A. Overall response rates were comparable between the groups. Conclusion: Naproxen demonstrates equal effectiveness, safety, and better tolerance compared to Aspirin in treating ARF patients.

Effectiveness of janus kinase inhibitors in relapsing giant cell arteritis in real-world clinical practice and review of the literature

BackgroundA substantial proportion of patients with giant cell arteritis (GCA) relapse despite standard therapy with glucocorticoids, methotrexate and tocilizumab. The Janus kinase/signal transducer and activator of transcription (JAK/STAT) signalling pathway is involved in the pathogenesis of GCA and JAK inhibitors (JAKi) could be a therapeutic alternative. We evaluated the effectiveness of JAKi in relapsing GCA patients in a real-world setting and reviewed available literature.MethodsRetrospective analysis of GCA patients treated with JAKi for relapsing disease at thirteen centers in Spain and one center in United States (01/2017-12/2022). Outcomes assessed included clinical remission, complete remission and safety. Clinical remission was defined as the absence of GCA signs and symptoms regardless of the erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) values. Complete remission was defined as the absence of GCA signs and symptoms along with normal ESR and CRP values. A systematic literature search for other JAKi-treated GCA cases was conducted.ResultsThirty-five patients (86% females, mean age 72.3) with relapsing GCA received JAKi therapy (baricitinib, n = 15; tofacitinib, n = 10; upadacitinib, n = 10). Before JAKi therapy, 22 (63%) patients had received conventional synthetic immunosuppressants (e.g., methotrexate), and 30 (86%) biologics (e.g., tocilizumab). After a median (IQR) follow-up of 11 (6-15.5) months, 20 (57%) patients achieved and maintained clinical remission, 16 (46%) patients achieved and maintained complete remission, and 15 (43%) patients discontinued the initial JAKi due to relapse (n = 11 [31%]) or serious adverse events (n = 4 [11%]). A literature search identified another 36 JAKi-treated GCA cases with clinical improvement reported for the majority of them.ConclusionsThis real-world analysis and literature review suggest that JAKi could be effective in GCA, including in patients failing established glucocorticoid-sparing therapies such as tocilizumab and methotrexate. A phase III randomized controlled trial of upadacitinib is currently ongoing (ClinicalTrials.gov ID NCT03725202).

Repair of inflammatory celiac artery aneurysm presenting with insidious onset of abdominal pain: A case report

BackgroundVisceral artery aneurysms (VAAs) are rare but potentially devastating given the high mortality associated with rupture. Current Society of Vascular Surgery guidelines recommend repair of these at 2.5 cm. Surgical intervention includes endovascular embolization and/or stenting versus open revascularization. This case presents a patient with a large celiac artery aneurysm (CAA) who underwent open ligation of the celiac artery at the origin. Splenectomy was performed given the need for ligation of the splenic artery. He had a replaced right hepatic artery from the SMA; thus, no revascularization was needed. Ultimately, the aneurysm was found to be inflammatory in etiology. Case reportA 41-year old male with history of seizure disorder, smoking, and newly diagnosed hypertension presented with abdominal pain for six months. His-laboratory work was significant for a leukocytosis of 17, 740, mildly elevated C- Reactive Protein (CRP) at 1.63, and normal erythrocyte sedimentation rate (ESR). CT angiogram revealed a 5.2 × 4.2 cm celiac artery aneurysm with stranding. Given its appearance and concern for infection, he underwent emergent laparotomy and ligation. Blood cultures and intraoperative tissues revealed no microorganism growth. Pathology was remarkable only for periarterial abscess with acute and chronic inflammation and focal tissue necrosis, compatible with aneurysm. ConclusionThis case report presents a rare inflammatory CAA, which presented with six months of abdominal pain, and its subsequent management with open intervention. In this case, his vessel anatomy was favorable for open repair with ligation of the celiac axis due to the presence of a replaced right hepatic artery. This also highlights the importance of anatomic vessel variants when making surgical decisions.

Development of clinical and laboratory biomarkers in an international cohort of 428 children with lupus nephritis.

Lupus nephritis (LN) is a very severe manifestation of lupus. There is no consensus on which treatment goals should be achieved to protect kidney function in children with LN. We retrospectively analyzed trends of commonly used laboratory biomarkers of 428 patients (≤ 18years old) with biopsy-proven LN class ≥ III. We compared data of patients who developed stable kidney remission from 6 to 24months with those who did not. Twenty-five percent of patients maintained kidney stable remission while 75% did not. More patients with stable kidney remission showed normal hemoglobin and erythrocyte sedimentation rate from 6 to 24months compared to the group without stable kidney remission. eGFR ≥ 90ml/min/1.73m2 at onset predicted the development of stable kidney remission (93.8%) compared to 64.7% in those without stable remission (P < 0.00001). At diagnosis, 5.9% and 20.2% of the patients showed no proteinuria in the group with and without stable kidney remission, respectively (P = 0.0001). dsDNA antibodies decreased from onset of treatment mainly during the first 3months in all groups, but more than 50% of all patients in both groups never normalized after 6months. Complement C3 and C4 increased mainly in the first 3months in all patients without any significant difference. Normal eGFR and the absence of proteinuria at onset were predictors of stable kidney remission. Significantly more children showed normal levels of Hb and erythrocyte sedimentation rate (ESR) from 6 to 24months in the group with stable kidney remission.

E075 Sacroiliitis potentially induced by isotretinoin: two case reports

Abstract Background/Aims Isotretinoin is a potent retinoid medication widely used to treat severe acne. Isotretinoin’s adverse effects range from well-documented dermatological side effects like dry skin to less common systemic manifestations. Sacroiliitis can arise from rheumatic and nonrheumatic causes. There has been limited attention in the literature to the rare occurrence of sacroiliitis as an adverse effect of isotretinoin. The precise mechanisms remain poorly understood, but the emergence of case reports suggests a potential link in immunomodulation through the alteration of cytokine balance and degradation of synovial membranes in joints. We present two patients with severe acne history who developed bilateral sacroiliitis within several weeks after starting isotretinoin Methods Case 1: A 19 year old male, started on 20 mg daily isotretinoin for acne vulgaris, experienced severe hip and lower back pain after one month, impacting his mobility. On examination, he displayed painful hip movements. Lumbar flexion was restricted and painful, with a 2 cm measurement on the Schober’s test. Medical investigation showed an elevation of erythrocyte sedimentation rate (ESR): 66mm/h, and C-reactive protein (CRP): 81 mg/l. HLA B27 was negative. X-ray radiography of the sacroiliac joint was normal, but the MRI examination showed the presence of bilateral sacroiliitis. Case 2: A 34 year old female received a six-months isotretinoin treatment for severe acne, with doses ranging from 20-40 mg daily. Then, in 2018, after a six-year gap, she received another isotretinoin course at 30 mg daily. Four months later, she began to experience gradual, intermittent lower back pain associated with 30 minutes of early morning stiffness. Her vital signs were stable, but she exhibited restricted and painful lumbar flexion. Her investigations revealed normal ESR and CRP. HLA B27 was negative. Her sacroiliac joint X-ray showed normal results, but her MRI indicated bilateral active sacroiliitis. Results Following the discontinuation of isotretinoin in both cases, NSAIDs were administered, which effectively relieved the pain. Our management of isotretinoin-induced sacroiliitis follows guidelines adapted from the ASAS-EULAR algorithm for axial spondyloarthritis. The algorithm entails an initial treatment with NSAIDs if no contraindications and to be titrated up to the maximum effective dose before considering biological/ targeted synthetic disease-modifying antirheumatic drugs. Conclusion The two cases highlight the rare but noteworthy association between isotretinoin therapy and sacroiliitis. In patients presenting with unexplained musculoskeletal symptoms during isotretinoin treatment at any point, clinicians should raise suspicions on the adverse effects of medication. Further research is needed to elucidate the immunomodulatory pathways involved in this association. Disclosure H. Almansoori: None. N. Alnuaimi: None. S. Alhosani: None. M. Alshehhi: None. S.A.

Arthrocentesis of suspected septic sternoclavicular arthritis: microbial yield and predictors of culture positivity.

Evaluate the microbial yield and factors predicting culture positivity for image-guided arthrocentesis of suspected septic sternoclavicular (SC) arthritis. An electronic health record search identified image-guided SC joint aspirations for suspected septic arthritis. Data was extracted by retrospective chart review including patient demographics, procedure characteristics, pre-procedure lab testing, joint culture results, final SC joint diagnoses and any effect of positive synovial cultures on subsequent antibiotic therapy. Factors associated with positive joint fluid cultures were assessed using a Chi-squared test for categorical predictors and logistic regression for continuous predictors. A total of 31 SC arthrocenteses met inclusion criteria with most (81%) performed using ultrasound guidance. Synovial fluid was successfully aspirated in 19/31 (61%) of cases, and in all other cases lavage fluid was successfully obtained. Synovial cultures were positive in 9/31 (29%) of cases. A final diagnosis of septic arthritis was assigned to 20/31 cases (65%) in which 9/20 (45%) had positive synovial cultures. There was no statistically significant association between synovial culture positivity and risk factors for septic arthritis, positive blood cultures, pre-aspiration antibiotics and whether synovial fluid or lavage fluid was cultured. Serum white blood cell count (WBC) and erythrocyte sedimentation rate (ESR) demonstrated statistically significant positive correlation with positive synovial cultures. Arthrocentesis is effective for microbial speciation in SC septic arthritis, and diagnostic yield may be increased with lavage when encountering a dry tap. Normal serum WBC and ESR values indicate an extremely low likelihood of positive synovial cultures.

Diagnostic difficulties in polymyalgia rheumatica cases with normal erythrocyte sedimentation rate and C-reactive protein values.

Polymyalgia Rheumatica (PMR) is an inflammatory disease which does not have specific diagnostic tests or pathological symptoms and is identified based on clinical characteristics. Among acute phase reactants (APR), the erythrocyte sedimentation rate (ESR) and C-Reactive Protein (CRP) are laboratory findings used in diagnosis and follow-up. In this study, it was aimed to determine the incidence of normal ESH and CRP in patients diagnosed with PMR and identify the distinguishing characteristics of these patients. PMR patients who were clinically diagnosed at a single center were reviewed. After the presence of bursitis was demonstrated with ultrasonography in patients with normal ESR and CRP rates, they were accepted to have PMR. Among all 54 patients (63% female), ESR and CRP values were normal in 8 patients (14%), and serum amyloid A (SAA) was determined to be elevated in all these patients. In the comparisons of the groups with normal and high levels of ESR and CRP, it was found that the group with normal ESR and CRP values had a younger age of diagnosis (P = .027), a longer symptom duration (P < .001), and a lower comorbidity rate (P = .010). PMR patients can have normal ESR and CRP values at the time of their diagnosis. While bursitis can be demonstrated with ultrasonography in patients who are clinically evaluated to have PMR, APRs such as SAA other than ESR and CRP can also be used.

Systemic-onset Juvenile Idiopathic Arthritis in a young child

We present a 31-month-old female child who was referred by the pediatricians with 1-year history of recurrent high-grade fever associated with polyarthritis and recurrent skin rash, which disappears within 24 hours of resolution of fever. She had lost the ability to walk unsupported because of persistent arthritis. Her Full Blood Count (FBC) was remarkable for marked leucocytosis, thrombocytosis, and a mild normocytic normochromic anemia; Erythrocyte Sedimentation Rate (ESR) and C-reactive Protein (CRP) were both elevated at 110mm/hour and 200mg/L (&lt;7) respectively while serial blood cultures were negative for septicemia and blood films were negative for acute leukemia; HIV, hepatitis B and C virus, tuberculosis, rheumatic fever, rheumatoid arthritis, and connective tissue disease screenings were all negative. Her hemoglobin genotype is AA. She had repeatedly received treatments for malaria and ‘sepsis’ with parenteral and oral antimalarials and antibiotics with no permanent relief, hence the reason for referral to the rheumatologist. An assessment of Systemic-onset Juvenile Idiopathic Arthritis (SoJIA) was made when her serum ferritin came back elevated at 670ng/mL (4.63 – 204) and she was commenced on oral ibuprofen with remarkable improvement evidenced by resolution of fever, joint pain and rash and normalization of ESR, CRP and serum ferritin within 8 weeks of treatment. Although SoJIA is rare, it would be worthwhile to include this disease in the differential diagnoses and subsequent evaluation in any child presenting with unexplained recurrent fever associated with body rash and polyarthritis.

Clinical Images: Tongue ulceration in giant cell arteritis associated with asymptomatic retinal ischemia

The patient, a 69-year-old female, presented with new-onset headache and facial and sinus pain initially treated by primary care with azithromycin for presumed sinusitis. Her erythrocyte sedimentation rate (ESR) was 114 mm/hour, and her C-reactive protein (CRP) level was 173.5 mg/l. Following antibiotics, she developed “thickened” tongue with white plaque (A) and was treated with oral nystatin for thrush. However, she subsequently developed masticatory and lingual claudication, a distal left tongue ulcer (A and B), and left temporal discomfort. A left temporal artery biopsy (TAB) showed histopathological findings consistent with giant cell arteritis (GCA). A retinal examination and fluorescein angiogram showed evidence of left eye retinal ischemia with presence of cotton wool spots, though asymptomatic and without visual field deficits. High-dose oral prednisone (100 mg/day) was started on the day of TAB (B). Within 48 hours, the headache and jaw and tongue claudication resolved. Seven days later, marked improvement in the tongue ulcer (C) was noted, and inflammatory markers had improved (ESR: 40 mm/hour; CRP level: 14.2 mg/l). Given significant clinical response, a prednisone taper without adjunct tocilizumab was used. A follow-up evaluation 3 months later (prednisone dose 10 mg/day) showed full resolution of the tongue ulcer (D), and the patient remained asymptomatic with a normal ESR (5 mm/hour) and CRP level (5.4 mg/l). Lingual manifestations in GCA include claudication, pain, edema, pallor, ulceration, and necrosis. Tongue claudication has been reported in approximately 3% of patients with GCA (1); however, tongue ulceration and frank necrosis are rare. GCA is considered the most common noninfectious vascular etiology of tongue necrosis, and its presence should prompt consideration and investigation for GCA. Visual ischemic features have been reported in up to 38% of patients with GCA with tongue ulceration or necrosis (2); therefore, all patients with GCA with tongue claudication or ulceration/necrosis should undergo detailed ophthalmologic examination. Prompt recognition and treatment initiation is paramount, and in this case, glucocorticoids preserved vision and resolved cranial and lingual symptoms.

Relationship Between Results of Genexpert RT-PCR and Erythrocyte Sedimentation Rate in Suspected Tuberculosis Patients

Pulmonary tuberculosis (TB) is an infectious disease that attacks the lungs and is caused by the bacterium Mycobacterium tuberculosis. The GeneXpert RT-PCR examination (Xpert MTB / RIF) is a development of a diagnostic tool that can automatically detect the presence of Mycobacterium tuberculosis (MTB) by molecular examination and can be used to detect MTB resistance to rifampicin. Erythrocyte sedimentation rate (ESR) is a test used to determine the rate at which erythrocytes settle in the blood. The purpose of this study was to determine the relationship between GeneXpert RT-PCR results and ESR in suspected tuberculosis patients. This research uses a cross-sectional study. The sample used in this study were 56 new suspected TB patients who had never been treated for ATD and underwent GeneXpert RT-PCR examination. Sampling was carried out by purposive sampling with the TCM Rif Sen group and negative results. A total of 27 patients (96.4%) with Rif Sen's GeneXpert RT-PCR results had high ESR values. 15 patients (53.6%) with negative GeneXpert RT-PCR results had normal ESR values. The results of the Chi Square test (X2) show that p-value = 0.000 OR = 0.032. There is a significant relationship between GeneXpert and ESR values ​​in suspected tuberculosis

Characterizing the Spectrum of Latent Mycobacterium tuberculosis in the Cynomolgus Macaque Model: Clinical, Immunologic, and Imaging Features of Evolution.

Mycobacterium tuberculosis infection outcomes have been described as active tuberculosis or latent infection but a spectrum of outcomes is now recognized. We used a nonhuman primate model, which recapitulates human infection, to characterize the clinical, microbiologic, and radiographic patterns associated with developing latent M. tuberculosis infection. Four patterns were identified. "Controllers" had normal erythrocyte sedimentation rate (ESR) without M. tuberculosis growth in bronchoalveolar lavage or gastric aspirate (BAL/GA). "Early subclinicals" showed transient ESR elevation and/or M. tuberculosis growth on BAL/GA for 60 days postinfection, "mid subclinicals" were positive for 90 days, and "late subclinicals" were positive intermittently, despite the absence of clinical disease. Variability was noted regarding granuloma formation, lung/lymph node metabolic activity, lung/lymph node bacterial burden, gross pathology, and extrapulmonary disease. Like human M. tuberculosis infection, this highlights the heterogeneity associated with the establishment of latent infection, underscoring the need to understand the clinical spectrum and risk factors associated with severe disease.

Clinical characteristics of 18 children with chronic nonbacterial osteomyelitis

Objective: To investigate the clinical features of children with chronic nonbacterial osteomyelitis (CNO), and raise awareness among clinicians. Methods: In this retrospective study, 18 patients with CNO who were diagnosed in Children's Hospital of Fudan University from January 2015 to December 2021 were included. Results: Eighteen children with CNO (12 males, 6 females) were identified. Their age at onset was 9 (5, 11) years, the delay in diagnosis was 2 (1, 6) months, and follow-up-was 17 (8, 34) months. The most common symptoms were fever in 14 children, as well as bone pain and (or) arthralgia in 14 children. In terms of laboratory results, normal white blood cell counts were observed at onset in 17 patients; increased erythrocyte sedimentation rate (ESR) in all patients; increased C reactive protein (CRP) over the normal value in 14 patients. Of the 18 patients, 2 had positive antinuclear antibodies, while none had positive human leukocyte antigen-B27 or rheumatoid factor. Imaging examination revealed that all the patients had symmetrical and multifocal skeletal lesions. The number of structural lesions detected by imaging investigation was 8 (6, 11). The most frequently affected bones were tibia in 18 patients and femur in 17 patients. Bone biopsy was conducted in 14 patients and acute or chronic osteomyelitis manifested with inflammatory cells infiltration were detected. Magnetic resonance imaging (MRI) found bone lesions in all the patients and bone scintigraphy were positive in 13 patients. All the patients were treated with nonsteroidal anti-inflammatory drugs, among whom 10 cases also treated with oral glucocorticoids, 9 cases with traditional disease modifying anti-rheumatic drugs, 8 cases with bisphosphonates and 6 cases with tumor necrosis factor inhibitors. The pediatric chronic nonbacterial osteomyelitis disease activity score, increased by 70% or more in 13 patients within the initial 6-month follow-up. Conclusions: The clinical manifestations of CNO are lack of specificity. The first symptom of CNO is fever, with or without bone pain and (or) arthralgia, with normal peripheral blood leukocytes, elevated CRP and (or) ESR. Whole body bone scanning combined with MRI can early detect osteomyelitis at subclinical sites, and improve the diagnostic rate of CNO.

Allogeneic Hematopoietic Cell Transplant Yields Long Term Disease Free Survival in a Significant Number of Patients with Classic Hodgkin Lymphoma

Background: Classic Hodgkin's lymphoma (cHL) is a highly curable disease. A minority of patients, however, will have relapse/refractory (RR) disease and these patients are challenging to manage especially those who relapse after autologous hematopoietic cell transplant (auto-HCT). Even though a number of salvage options are available for these patients none of them is considered curative except allogeneic hematopoietic cell transplant (allo-HCT). Design and Methods: Retrospective analysis of 33 patients who had allo-HCT using matched family donors for cHL between January 2007 and December 2021. Continuous variables were summarized using medians and ranges. Categorical variables were summarized using frequencies and percentages. Probabilities of overall survival (OS) and disease free survival (DFS) were calculated using Kaplan-Meier estimate. Statistical analysis was conducted sing R studio (version 1.3.959 © 2009-2020 RStudio, PBC). Results: The median patient age at allo-HCT was 27 years. Seventeen patients were males and 16 were females. Five patients had early stage disease (Ann Arbor stage I, II) and 28 had advanced stage disease (Ann Arbor III, IV). Regarding the histologic type of cHL, eighteen had nodular sclerosis (NS), eight had mixed cellularity (MC), one had lymphocyte rich (LR), one had lymphocyte depleted (LD) and five cases were labeled as classic HL without further classification. Seventeen patients received brentuximab vedotin and fourteen patients received check point inhibitors prior to allo-HCT. The median number of chemotherapy lines prior to allo-HCT was 4 (range: 2-8). Twenty seven patients had chemosensitive disease (complete or partial remission) while 6 patients had chemoresistant disease (stable or progressive) prior to allo-HCT. Twenty seven patients had undergone auto-HCT prior to allo-HCT. Eighteen patients had elevated (>50) erythrocyte sedimentation rate (ESR) while 15 had normal ESR prior to allo-HCT. The majority of patients were conditioned with a reduced intensity regimen (29 patients versus 4 patients conditioned with myeloablative regimen). Twenty five patients received non-TBI (total body irradiation) based conditioning while 8 patients had TBI based regimen. The most frequently used conditioning regimen was fludarabine + melphalan. Nine patients received ATG (anti thymoglobulin) as a part of the conditioning while 24 patients did not. Thirty one patients received peripheral blood graft while 2 patients received bone marrow graft. The five years DFS was 37.5%. Twenty seven % of patients had acute GVHD (graft versus host disease) and 48% had chronic GVHD. The effect of a number of variables (number of chemotherapy lines, pre-allo-HCT ESR, conditioning intensity, ATG vs no ATG, receipt of pre-allo-HCT brentuximab or check point inhibitors, prior auto-HCT, chemosensitivity pre-allo-HCT and histologic subtype) was tested on the DFS. The only two variable that were statistically associated with a better DFS were pre-allo-HCT chemosensitivity (P=0.006) and non-NS histologic subtype (P=0.027). (Figure 1 and 2). Conclusions: Allogeneic stem cell transplantation can result in long-term progression-free survival in heavily pre-treated patients with Hodgkin's lymphoma. Patients with no response to salvage chemotherapy pre-allo-HCT and patients with NS subtype had detrimental outcomes. Better selection of patients before allo-HCT can result in a higher cure rates.

Erythrocyte sedimentation rate in COVID-19 patients treated at the CLAS health center, Nuevo Lurín, 2021

Background: The erythrocyte sedimentation rate (ESR) is used for diagnosis in inflammatory processes, including during the coronavirus disease 2019 (COVID-19) pandemic affecting our population. To determine the values of ESR in the evolution of patients with COVID-19 undergoing treatment at the CLAS Health Center in Nuevo Lurín. Methods: Our research applied a quantitative-observational, descriptive, and longitudinal approach. The sample consisted of 26 male and 19 female patients treated at the study site between February and June 2021, none of whom were in critical condition. To collect all the necessary information, the Capillary or Wintrobe method was used to determine the values of ESR in the evolution of the COVID-19 patients, obtaining different values for the 45 patients seen at the study site. The normal ESR value was 0 - 15mm/h for males and 0 - 20mm/h for females. Results: The initial ESR test in patients positive for COVID-19 showed that only two cases (0.04%) had slightly elevated ESR ranges, while in the rest of the values (95.56%) remained within the normal range. Conclusions: From the results of the capillary velocity of sedimentation method, it can be concluded that patients with COVID-19 in Peru showed no signs of inflammation within their bodies due to the virus.

230. The preoperative inflammatory state is an independent risk factor for short term postoperative complications in adult spinal deformity patients

<h3>BACKGROUND CONTEXT</h3> Preoperative risk stratification is critical to determining which adult spinal deformity (ASD) patients may develop postop complications and to maximize surgical success. Currently it is unknown if a preoperative inflammatory state results in a higher risk for postop complications. This information can be used in risk stratification models to aid in complication avoidance. <h3>PURPOSE</h3> To determine if patients with preoperative elevated serum markers for inflammation have higher rates of postoperative complications <h3>STUDY DESIGN/SETTING</h3> Retrospective review of multicenter prospective ASD database. <h3>PATIENT SAMPLE</h3> ASD patients. <h3>OUTCOME MEASURES</h3> C-reactive protein (CRP), Erythrocyte sedimentation rate (ESR), complications by type and by severity of intervention: none, mild, moderate and severe. Demographic and surgical variables: age, estimated blood loss (EBL), operating room (OR) time, body mass index (BMI), America Society of Anesthesia physical classification scale (ASA), Charlson comorbidity index (CCI), Edmonton frailty scale (EF), 3-column osteotomy (3CO), number of post fusion levels. <h3>METHODS</h3> Preoperative labs were drawn on ASD patients and the inflammatory markers were CRP and ESR. CRP thresholds for cardiac risk: normal = 3. The CRP moderate and elevated values were combined into one group named elevated. Normal ESR thresholds: Male age 50, =20, Female >50, =30. Patients were stratified by having normal or elevated markers and rates of complications were compared between the groups. A multivariate model with CRP/ESR and demographic/surgical variables for postoperative complications. Health-related quality of life (HRQOL) metrics were compared <h3>RESULTS</h3> The total number of patients with preoperative CRP was 159 and ESR was 158. CRP: normal=114 patients (71.7%), moderate elevation=28 (17.6%), severe elevation=17 (10.7%). Combined elevated=45/159(28.3%). Elevated ESR=25(15.8%), normal=133(84.2%). The elevated CRP group had significantly higher rate of moderate complication 13/45(28.9%) vs 16/114(14.0%), p=0.03 and severe complication 15/45 (33.3%) vs 17/114(14.9%, p=0.009. Elevated ESR patients had significantly higher rate of moderate complication 9/25 (36.0%) vs 20/133 (15.0%), p=0.01. In multivariable logistic regression elevated CRP had odds ratio for moderate complication of 3.3 (95% CI 1.4-7.6, p=0.006), and for severe complication of 2.3 (95% CI 1.05-5.1, p=0.037). Multivariable logistic regression for elevated ESR and moderate complication had odds ratio of 2.9 (95%CI 1.04-7.8, p=0.041). Elevated CRP also had significantly higher rate of wound complications (15.6% vs 3.5%, p=0.007) and MSK complications (11.1% vs 1.8%, p=0.01). Elevated ESR had significantly higher rate of cardiac complications (32.0% vs 13.5%, p=0.02) and neurological complications (24.0% vs 9.0%, p=0.03). Elevated CRP had worse preoperative leg pain, SRS Activity and VR12 PCS(p<0.05). Elevated ESR had worse baseline ODI (p=0.03). <h3>CONCLUSIONS</h3> A preoperative inflammatory state as defined by elevated CRP and ESR is an independent risk factor for the development of moderate and severe postop complications. Having elevated preop CRP is 3.3 and 2.3 times more likely to have a moderate and severe complication, respectively. Elevated ESR is 2.9 times more likely to have a moderate complication. This data can be used in risk stratification models to aid in minimizing postoperative complications. <h3>FDA DEVICE/DRUG STATUS</h3> This abstract does not discuss or include any applicable devices or drugs.
