Bridging distances and saving costs: insights from a pilot project of telerheumatology in a rural area of Pakistan.

Enhancing access to healthcare remains a formidable challenge in rural regions of low- and lower-middle-income countries. Amid evolving healthcare challenges, telerheumatology provides opportunities to bridge gaps and expand access to rheumatology care, particularly in remote areas. We describe a pilot telerheumatology program and its cost-, time-, and travel-saving potential in a remote rural setting in northern Pakistan. The telerheumatology program commenced at the Pakistan Institute of Medical Sciences Islamabad, providing services through video consultations to a basic health unit in the Gilgit-Baltistan region. Patients visiting from the Gilgit-Baltistan region willing to participate were recruited in the program. Demographics and logistical metrics were recorded in a dedicated registry. A total of 533 consultations were carried out from April 2022 to April 2023. The majority of the patients were female (318/533, 59.7%). The median age of patients was 50 ± 15.7 years. The average wait time for consultation was 20 ± 13 min. The average travel time to reach telecentre was 59 ± 53 min. The average travel cost to reach telecentre was 379 ± 780 PKR (1.85 ± 3.81 USD). The average duration of consultation was 15 ± 5 min. The most common diagnosis for consultation was knee osteoarthritis (237, 44.5%), chronic low back pain (118, 22.1%), and rheumatoid arthritis (42, 7.9%). On average, patients saved 787 ± 29 km of distance, 15 ± 1 h of traveling, and 6702 ± 535 PKR (33 ± 3 USD) that would have been required to travel to our tertiary care hospital. Telerheumatology substantially reduced travel time, distance, and cost for patients. It has the potential to deliver outpatient rheumatology consultation in an economically efficient manner, effectively breaking geographical barriers and expanding access to essential services for patients in remote areas.

Comparison of efficacy three-site versus single-site steroid injections for the treatment of adhesive capsulitis.

Background: Frozen shoulder or adhesion capsulitis is a frequent ailment that causes pain and progressively restricts both active and passive shoulder motions. It is estimated that it affects 2%-5% of the general population and up to 20% of diabetes mellitus patients.We aimed to compare the effectiveness of three-site steroid injections against one-site injections in the treatment of adhesive capsulitis. Methodology: The Rheumatology Department of Pakistan Institute of Medical Sciences in Islamabad conducted this cross-sectional study. Between August 2021 to December 2021. The study comprised a total of 98 patients. This study included patients of both genders with shoulder pain between the ages of 40 and 70.Patients were divided into two groups & dosage was given at Sub-coracoid, Subacromial, and Posterior Capsule.The CONSTANT score was used to assess patients three times (Initial, 3months & 6 months later). Results: The average age, gender distribution, and dominant/non-dominant side ratio of the participants were nearly identical between the two groups. More patients in group B (77.22 8.17) had a higher mean CONSTANT score than those in group A (72.73 7.05). Patients were checked in on again after three and six months. Conclusion: The three-site injection technique is a safe and effective method for frozen shoulder. It provides an early recovery and improved shoulder function with a reduced frequency of relapse as compared to single-site injection techniques.

Associated Factors With Uremic Pruritus in Chronic Hemodialysis Patients: A Single-Center Observational Study.

Background and objectives Uremic pruritus is a recurrent and delicate manifestation in patients suffering from end-stage renal disease. It is a consequence of multiple factors, primarily comprising of metabolic factors and complement activation along with interleukins. The objective of our study was to find out the associated factors of uremic pruritus in chronic hemodialysis patients. The secondary aim was to obtain cut-off values of all the markers predicting pruritus. Materials and methods A cross-sectional observational study was conducted in the nephrology department of a tertiary care hospital including 135 patients. The current occurrence of pruritus was diagnosed on the basis of a validated and reliable scale of pruritus among chronic kidney disease (CKD) patients in the local language. Multivariate logistic regression and receiver operating characteristic analysis were conducted to decipher the required objectives. Results Study participants had a mean age of 56.29 ± 10.51 years with 56.3% males and 43.7% females. Hypertension was frequent comorbidity (75.6%) followed by diabetes (51.9%). Mean body mass index (BMI), duration of CKD diagnosis, and hemodialysis onset were 26.55 ± 5.37 kg/m2, 6.58 ± 3.65 years, and 3.32 ± 2.09 years respectively. Pruritus was reported in 37.0% of the study participants. On multivariate logistic regression, presence of skin allergy (aOR: 8.100 [2.926-22.420], p<0.001), phosphate >4.5 mg/dL (aOR: 3.889 [1.118-15.532], p=0.033), female gender (aOR: 3.592 [1.337-9.655], p=0.011), albumin <3.5 g/dL (aOR: 2.987 [1.156-7.716], p=0.024) and potassium >5.1 mEq/L (aOR: 2.934 [1.030-8.355], p=0.044) were found significantly associated with pruritus. Conclusion Many factors were linked to pruritus in hemodialysis patients in the current study. The current study also significantly correlated certain factors with pruritus independently.

A CROSS-SECTIONAL SCREENING SURVEY ON THE SEROPREVALENCE OF HEPATITIS B AND HEPATITIS C AMONGST THE GENERAL POPULATION OF RURAL DISTRICTS OF SINDH, PAKISTAN.

BACKGROUND: Viral hepatitis is a global phenomenon, with the disease burden varying on a daily basis. Amongst chronic infections, hepatitis B virus and hepatitis C virus (HCV) are egregiously linked to severe health-related complications, with a worldwide prevalence of 248 million and 71 million respectively. Amongst the developing world, a hand full of countries are exhibiting a gross decline in chronic viral infection prevalence, like Bangladesh. While countries such as India have a consistent prevalence, Pakistan bears one of the largest proportions of chronic viral hepatitis globally with increasing trends shown year-by-year. Various old literature texts have stated an approximate national prevalence rate around 2.6% and 5.3% of hepatitis B and C respectively. OBJECTIVE: The objective of this study was to determine the current seroprevalence rates of chronic viral hepatitis amongst the general population of rural Sindh using a screening program to determine the current disease burden. METHODS: An observational, cross-sectional survey based on a screening program was conducted in 5 districts with a combined population of over 6.5 million. The screening was carried out via the administration of various camps with the assistance of local social workers and welfare organizations. A total of 24,322 individuals met the inclusion criteria and were screened through (HBsAg/HCV) rapid test cassette (WC) Imu-Med one-step diagnostic test. RESULTS: Hepatitis B was found positive in 964 (3.96%) individuals including 421 (43.67%) males and 543 (56.32%) females, while hepatitis C was positive in 2872 (11.80%) individuals including 1474 (51.32%) males and 1398 (48.67%) females. The prevalence amongst the districts varied between 0.97% and 9.06% for hepatitis B, and 1.61% and 29.50% for hepatitis C, respectively. Umerkot was found to be the most prevalent district amongst rural Sindh, while Badin had the least number of seropositive people. The second most prevalent district of the study population was found to be Tando Allahyar followed by Mirpur Khas. The combined seroprevalence of 15.76% was calculated for hepatitis B and C together amongst the five studied districts of rural and peri-urban Sindh. CONCLUSION: The alarmingly high prevalence rates revealed in our study warrant the urgent need to generate multiple effective strategies in the region to enhance awareness amongst the general population regarding screening, prevention, and prompt treatment of the disease.

RESUMO CONTEXTO: A hepatite viral é um fenômeno global, com a intensidade da doença variando diariamente. Entre as infecções crônicas, o vírus da hepatite B e o vírus da hepatite C (VHC) estão fortemente ligados a complicações graves relacionadas à saúde, com prevalência mundial de 248 milhões e 71 milhões, respectivamente. Entre o mundo em desenvolvimento, uma quantidade de países está exibindo um declínio bruto na prevalência de infecção viral crônica, tal como Bangladesh. Embora países como a Índia tenham uma prevalência consistente, o Paquistão tem uma das maiores proporções globais de hepatite viral crônica, com tendências crescentes mostradas ano a ano. Vários textos da menos recentes têm declarado uma taxa de prevalência nacional aproximada em torno de 2,6% e 5,3% da hepatite B e C, respectivamente. OBJETIVO: O objetivo deste estudo foi determinar as atuais taxas de soroprevalência da hepatite viral crônica entre a população geral do Sindh rural utilizando um programa de triagem para determinar a carga atual da doença. MÉTODOS: Foi realizada uma pesquisa observacional e transversal baseada em um programa de triagem combinada em cinco distritos com população de mais de 6,5 milhões. A triagem foi realizada por meio da administração de diversos acampamentos com o auxílio de assistentes sociais locais e organizações de assistência social. Um total de 24.322 indivíduos atenderam aos critérios de inclusão e foram examinados através do teste rápido (HBsAg/VHC) Imu-Med em uma etapa. RESULTADOS: Hepatite B positiva foi encontrada em 964 (3,96%) indivíduos incluindo 421 (43,67%) homens e 543 (56,32%) mulheres, enquanto hepatite C foi positiva em 2.872 (11,80%) indivíduos incluindo 1.474 (51,32%) homens e 1.398 (48,67%) mulheres. A prevalência entre os distritos variou entre 0,97% e 9,06% para hepatite B, e 1,61% e 29,50% para hepatite C, respectivamente. Umerkot foi encontrado como o distrito mais prevalente entre Sindh rural, enquanto Badin tinha o menor número de pessoas soropositivas. O segundo distrito mais prevalente da população de estudos foi encontrado como Tando Allahyar, seguido por Mirpur Khas. A soroprevalência combinada de 15,76% foi calculada para hepatite B e C em conjunto entre os cinco distritos estudados do Sindh rural e periurbano. CONCLUSÃO: As taxas de prevalência alarmantemente reveladas em nosso estudo justificam a necessidade urgente de gerar múltiplas estratégias efetivas na região para aumentar a conscientização da população em geral sobre rastreamento, prevenção e tratamento rápido da doença.

Characteristics of Asymptomatic Bacteriuria in Diabetes Mellitus Patients: A Retrospective Observational Study.

Background and objective The term asymptomatic bacteriuria (ASB) refers to the isolation of bacteria in a urine specimen of individuals without any symptoms of urinary tract infection (UTI). Diabetes mellitus (DM) is a disease involving multiple organ systems, characterized by its chronicity and hence endless complications including ASB. This study aimed to determine the characteristics of ASB and antibiotic susceptibility patterns among patients with diabetes. Materials and methods This was a retrospective observational study conducted in a tertiary care hospital. The study included patients with a diagnosis of diabetes with no signs and symptoms of UTI but who still showed the growth of an organism in urine culture. A total of 222 urine cultures were analyzed retrospectively, ensuring that they met the inclusion criteria through non-probability consecutive sampling. Results The mean age of the study participants was 62.89 ± 13.77 years; 76% of them were females, and 61% had a family history of diabetes. The most frequent organisms isolated were Escherichia coli (E. coli), Enterococcus, Klebsiella pneumonia, Pseudomonas aeruginosa, and Enterobacter species. A total of 20 subjects had dual bacterial growth in their cultures, with Enterococcus species (n=17) being the most common organism. Gender, family history of diabetes, levels of hemoglobin A1c (HbA1c), and advanced age were all found significantly associated with ASB. Conclusion Our study is the first of its kind to analyze and examine the risk factors associated with ASB in DM patients, and to identify the pathogens involved, along with assessing their antibiotic resistance profiles.

Clinical, epidemiological, and diagnostic characteristics of esophageal carcinoma in a Pakistani population.

BACKGROUND: Esophageal cancer ranks eighth among the most prevalent cancers globally and is the sixth leading cause of mortality from malignancy worldwide; it is the 7th most prevalent malignancy in males and the 6th most prevalent malignancy in females. In Pakistan, the incidence is 4.1 per 100 000 with the province of Baluchistan having the greatest incidence. OBJECTIVE: Report trends and characteristics of esophageal cancer in Pakistan over the past 10 years. DESIGN: Cross-sectional, retrospective review of medical records. SETTING: Tertiary care hospital. PATIENTS AND METHODS: The study included all patients admitted with a diagnosis of esophageal carcinoma with a mass lesion or luminal narrowing. The records were for the period from January 2011 to September 2020. MAIN OUTCOME MEASURES: Gender, histopathological types/differentiation along with clinical/laboratory findings. SAMPLE SIZE: 1009 with a mean (standard deviation) age of 49.3 (14.2) and a median (interquartile range of 50 (22) years (443 males and 566 females with age of 51.0 [20] years and 47.9 [23.8] years, respectively). The male-to-female ratio was 1:1.2. RESULTS: Most patients (82.7%) had squamous cell carcinomas with a male-to-female ratio of 1:2; the remainder had adenocarcinomas with a male-to-female ratio of 4:1 (P<.001). Dysphagia, weight loss, and vomiting were the most prevalent symptoms. More adenocarcinoma masses were located distally compared with squamous cell carcinomas (P=.030), lesions were most likely to be ulcerated (P=.910). Luminal narrowing was slightly more frequent in squamous cell carcinoma (P=.215), thickening was more prominently circumferential in the adenocarcinomas. In squamous cell carcinoma, the most common variant was moderately differentiated while moderate to poorly differentiated variants were more common in adenocarcinoma. In the survival analysis, squamous cell carcinoma (P=.014 vs adenocarcinoma), particularly the well-differentiated type (P=.018 vs other variants), projected a better prognosis. CONCLUSION: Our study reports the most recent trends of esophageal carcinoma in this region. LIMITATIONS: Lack of metastatic workup, TNM staging, and mode of treatment, along with the overlapping pattern of histological variants. CONFLICT OF INTEREST: None.

Assessing the Mental Impact and Burnout among Physicians during the COVID-19 Pandemic: A Developing Country Single-Center Experience.

Health-care workers are on the front line to combat the peculiar coronavirus disease-19 (COVID-19) pandemic and are susceptible to acquiring this infection. This study is aimed at documenting the effect of "coronaphobia" on mental well-being and to report burnout among physicians. The study was conducted as a cross-sectional survey between November 17, 2020 and January 1, 2021 via a Google form distributed among the physicians of a tertiary care hospital, in Karachi, Pakistan. The Warwick-Edinburgh Mental Well-being Scale (WEMWBS) was used to assess the mental well-being of physicians. Burnout was documented by using the Maslach Burnout Inventory Human Services Survey for Medical Personnel. Eighty-seven physicians participated in the survey (mean age, 30.9 ± 7.3 years). The mean WEMWBS score of the study participants was 51.6 ± 10.8. Regarding the WEMWBS, emotional exhaustion was observed in 54% (N = 47) of participants, depersonalization in 77% (N = 67), and low personal accomplishment was reported in 31% (N = 27) of participants. The results of the survey further highlight that depersonalization, emotional exhaustion, and low personal accomplishment were associated significantly with a history of COVID-19 infection and COVID-19 postings. Hence, immediate measures are required to reduce the burnout among physicians while battling the second wave of the pandemic.

OCCURRENCE OF UNUSUAL HAEMOGLOBINOPATHIES IN BALOCHISTAN: HB SD AND HB SE - PRESENTATION WITH OSTEOMYELITIS.

OBJECTIVE: To describe two cases of unusual variants of sickle cell disease. CASE DESCRIPTION: We present two cases of sickle cell disease variants (haemoglobinopathies), from unrelated families, in the state of Balochistan (Pakistan). One was diagnosed with sickle cell disease in the haemoglobin electrophoresis, whereas the other was diagnosed with sickle cell SE disease. Both were diagnosed based on the presentation of osteomyelitis. COMMENTS: Haemoglobin SD disease (Hb SD) and haemoglobin SE disease (Hb SE) are rare haemoglobinopathies in the world. The lack of available literature suggests that both are variants of sickle cell disease (SCD), with heterogeneous nature. The prevalence of sickle cell disease with compound heterozygotes was found at a variable frequency in the population of the Asian Southeast. The frequency of osteomyelitis in SCD is 12 to 18%, but its occurrence among variant haemoglobinopathies is little reported. Both reported cases presented with osteomyelitis as a characteristic of the disease presentation.

Characteristics of Asymptomatic Bacteriuria in Patients with Chronic Kidney Disease: A Tertiary Care Hospital Experience from a Developing Country.

Asymptomatic bacteriuria (ASB) is the isolation of bacteria in a urine sample from individuals who do not have any symptoms of a urinary tract infection (UTI). The outcomes of ASB in chronic kidney disease (CKD) patients are poorly understood in Pakistan. This study aimed to determine the characteristics of ASB and antibiotic susceptibility pattern among patients with CKD. A cross-sectional retrospective survey was administered to perform this study in a tertiary care hospital, to include all CKD patients. The study included all those patients with a diagnosis of CKD with no signs and symptoms of UTI present, and showing the growth of an organism in urine culture. A total of 175 urine cultures were observed retrospectively meeting the inclusion criteria through nonprobability consecutive sampling. Out of 175 urine cultures observed, mean age of 58.56 ± 16.81, 71% of them were females, 55% were diabetic, and 22% had a family history of CKD. Escherichia coli, Enterococcus, Klebsiella, Pseudomonas, Enterobacter, and streptococcal species were the most often isolated microbes. A total of 17 subjects got dual bacterial growth in their cultures which were having Enterococcus species as the most common organism. Twenty-three cultures were identified as pandrug resistant (13.14%), only sensitive to colomycin/polymyxin B. The susceptibilities of these organisms were contrasting to traditional antibiotics known to treat UTIs empirically, hence demanding further screening and treatment protocols to be defined for minimizing the irrational choice of antibiotics.

Frequency of deranged renal profile in patients with COVID-19: Tertiary Care Experience from a developing country.

Coronavirus disease-2019 (COVID-19) is a global pandemic, also affecting Pakistan with its first case reported on February 26, 2020. Since then, it has been declared a pandemic by the World Health Organization. Our study aimed to evaluate the renal derangements associated with COVID-19 infection in our population. A retrospective, observational study was conducted to include all the admitted patients having COVID-19 positive, and evaluated those for derangements of renal function (n = 362). Out of the 362 patients, 229were admitted in the ward, 133 were in intensive care unit (ICU), 258 of them recovered, while 104 deaths reported. At admission, the renal profile was deranged in almost one-half of ICU admissions and mortalities which increased to two-third during the hospital stay, with around 80% of deaths reported with increased urea and creatinine levels. Among the deceased patients, around one-third of the mortalities developed renal profile derangements during the hospital stay although they were admitted with a normal renal profile. An estimated glomerular filtration rate showed a mean increase of 13.37 mL/min/1.73 m2 during the hospital stay of surviving patients, while a decline of 19.92 in nonsurviving patients. A hazard ratio of 3.293 (P <0.001) for admitting serum urea and 3.795 (P = 0.009) at discharge and for serum creatinine at 5.392 (P <0.001) on discharge was associated significantly with mortality. Kaplan-Meier plot showed a significant decline in days of survival with deranged urea and creatinine (P <0.001). The deranged renal function in COVID-19 patients is associated with an increased number of ICU admissions as well as mortalities.

Occurrence of unusual haemoglobinopathies in balochistan: hb sd and hb se - presentation with osteomyelitis / Ocorrência de hemoglobinopatias incomuns no baluchistão: hb sd e hb se - apresentação com osteomielite

ABSTRACT Objective: To describe two cases of unusual variants of sickle cell disease. Case description: We present two cases of sickle cell disease variants (haemoglobinopathies), from unrelated families, in the state of Balochistan (Pakistan). One was diagnosed with sickle cell disease in the haemoglobin electrophoresis, whereas the other was diagnosed with sickle cell SE disease. Both were diagnosed based on the presentation of osteomyelitis. Comments: Haemoglobin SD disease (Hb SD) and haemoglobin SE disease (Hb SE) are rare haemoglobinopathies in the world. The lack of available literature suggests that both are variants of sickle cell disease (SCD), with heterogeneous nature. The prevalence of sickle cell disease with compound heterozygotes was found at a variable frequency in the population of the Asian Southeast. The frequency of osteomyelitis in SCD is 12 to 18%, but its occurrence among variant haemoglobinopathies is little reported. Both reported cases presented with osteomyelitis as a characteristic of the disease presentation.

RESUMO Objetivo: Descrever dois casos de variantes raras da hemoglobinopatia falciforme. Descrição do caso: Apresentamos aqui dois casos de hemoglobinopatias variantes das células falciformes, de famílias não relacionadas, no estado do Baluchistão (Paquistão), sendo um diagnosticado como doença da hemoglobina SD na eletroforese de hemoglobina, enquanto o outro com doença da hemoglobina SE. Ambos foram diagnosticados a partir da apresentação de osteomielite. Comentários: Hemoglobina SD (Hb SD) e hemoglobina SE (Hb SE) são hemoglobinopatias raras no mundo. A escassez de literatura disponível sugere que ambas são variantes da doença falciforme (DF) com natureza heterogênea. A prevalência de hemoglobinopatia falciforme com heterozigosidade composta foi encontrada com frequência variável na população do sudeste asiático. A frequência de osteomielite na DF é de 12 a 18%, mas sua ocorrência entre as hemoglobinopatias falciformes variantes é pouco relatada. Os dois casos reportados apresentaram osteomielite como característica de apresentação da doença.

Prognostic Value of Preoperative Pro-B-Type Natriuretic Peptide: Early Predictor of Cardiovascular Complications and Mortality After Major Abdominal Surgery.

Background and objectives In surgical patients, coronary disease is the main cause of perioperative mortality. The incidence of serious cardiovascular complications is reported as 5% with a probability of 1-2% of death from the cardiac cause in major non-cardiac surgery. B-type natriuretic peptide (BNP) is a sensitive and specific predictor of left ventricular systolic dysfunction and predicts first cardiovascular event and death in the general population. The recent guidelines recommended the use of pro-BNP for independent perioperative prognosis in cardiac patients undergoing non-cardiac surgery. The aim of this study is to assess the predictive value of raised pro-BNP levels in patients who underwent major abdominal surgery and evaluate its relationship with cardiovascular complications and mortality occurring up to 30 days after surgery. Materials and methods We reviewed the medical records of patients undergone surgical procedures in the abdominal region lasting more than two hours, requiring postoperative high dependence or intensive care and an expected hospital stay of at least three days. All types of open or laparoscopic-assisted abdominal or pelvic surgeries that were evaluated for preoperative pro-BNP levels were included in the study. During the postoperative period, all patients were followed for cardiac complications and mortality for 30 days after surgery. Postoperative adverse cardiac events were predefined as angina pectoris, myocardial infarction, cardiogenic dyspnea, acute arrhythmias (atrial fibrillation/flutter, ventricular fibrillation/tachycardia), acute hypertensive event (hypertensive emergency or urgency), congestive heart failure, acute pulmonary edema, or primary cardiac death. While non-cardiac complications were also documented as either pulmonary, septic, postsurgical site infection, and other systemic complications. Subsequently, a survival analysis was done for the discretion of cardiovascular complications and mortality. Results The mean age of the study population was found to be 50.22 ± 14.28 years, mean pro-BNP levels were 909.29 ± 3950.04, and mean days of hospital stay were 7.43 ± 4.49 days. The 30-day postoperative all-cause mortality was found to be 9.8%. Hypertension and diabetes were frequent comorbidities amongst the study population. The mean preoperative pro-BNP levels were found higher in the male gender (p=0.071), also found higher in those with cardiovascular complications (p=0.006) and mortality (p=0.057). Receiver operating characteristic (ROC) analysis showed cardiovascular outcomes with a cut-off value of pro-BNP at 143 pg/ml, AUC of 0.891, at a sensitivity of 91%, positive predictive value (PPV) of 96%, a specificity of 75%, and negative predictive value (NPV) of 58%, while the same for mortality at a cut-off value of 164 pg/ml was found with AUC of 0.815, at a sensitivity of 84%, a specificity of 66%, PPV of 97%, and NPV of 21%. The unadjusted odds ratio for cardiovascular complications was found to be 17.857 (95% CI: 6.56-48.60) while that for mortality was 10.863 (95% Cl: 2.29-51.37). The Kaplan-Meier survival curves showing elevated pro-BNP levels were significantly associated with cardiovascular events, with 30 days mortality at a cut-off value of 164 pg/ml. Conclusion Pro-BNP is a useful marker in postoperative patients for not only predicting cardiovascular outcomes as cited by many previous studies but also mortality.

Hematological parameters predicting severity and mortality in COVID-19 patients of Pakistan: a retrospective comparative analysis.

BACKGROUND AND OBJECTIVES: COVID-19 is a global pandemic. In our study, we aimed to utilize the hematological parameters in predicting the prognosis and mortality in COVID-19 patients. MATERIALS AND METHODS: A retrospective, observational study was conducted to include all the admitted patients (n = 191) having COVID-19 Polymerase chain reaction (PCR) positive, and evaluated those for prognosis and disease outcome by utilizing several biochemical and hematological markers. RESULTS: Amongst the patients admitted in the ward versus in the intensive care unit (ICU), there were significant differences in mean hemoglobin (P = 0.003), total leukocyte count (P = 0.001), absolute neutrophil and lymphocyte counts (P < 0.001), absolute monocyte count (P = 0.019), Neutrophil-to-Lymphocyte ratio (NLR) and Lymphocyte-to-Monocyte ratio (LMR) (P < 0.001), Platelet-to-Lymphocyte ratio (PLR) and Lymphocyte-to C-reactive protein ratio (LCR) (P = 0.002), and C-reactive protein (CRP) levels (P < 0.001). Amongst the deceased patients, there was significant leukocytosis (P = 0.008), neutrophilia and lymphopenia (P < 0.001), increased NLR (P = 0.001), decreased LMR (P < 0.001), increased PLR (p = 0.017), decreased LCR (p = 0.003), and elevated CRP level (P < 0.001). A receiver operating characteristic curve obtained for the above parameters showed NLR (AUC: 0.841, PPV: 83.6%) and PLR (AUC: 0.703, PPV: 81.8%) for ICU patients, while NLR (AUC: 0.860, PPV: 91.1%) and PLR (AUC: 0.677, PPV: 87.5%) for the deceased patients had significant accuracy for predicting the disease severity of COVID-19 in comparison to survivors. CONCLUSION: The inflammatory markers and hematological indices are a good guide for predicting the severity and disease outcome of coronavirus disease. NLR and PLR are elevated in severe disease while LMR and LCR are inversely correlating with disease severity.

Pericardial Tumor, a Rare Manifestation of Sjogren's Syndrome Secondary to Systemic Lupus Erythematosus.

We are presenting a case of pericardial tumor in an elderly female patient who presented with low-grade fever, purpuric rashes all over the body, grittiness in the eyes, and dry mouth with decreased oral intake, night sweats, weight loss, chest pain, and dyspnea. She was diagnosed with Sjögren's syndrome secondary to systemic lupus erythematosus (SLE) with positive anti-nuclear antibody (ANA), anti-double-stranded DNA (anti-ds-DNA), and anti-Sjögren's-syndrome-related antigen A autoantibodies (SS-A/Ro) antibodies. Computerized tomography scan of the chest with contrast showed multiple calcified mediastinal lymph nodes and a well-defined solid cystic lesion adjacent to the left atrial appendage in favor of a pericardial tumor with minimal pericardial effusion. Biopsy could not be done due to the risk of cardiac tamponade and pneumothorax secondary sensitive location of the tumor. The patient was referred to the oncology and cardiothoracic surgery department for an opinion regarding resection of the tumor and further palliative management. This case is unique in a way that the current literature does not associate SLE with pericardial tumor, while our patient had no other primary malignancy or secondary metastasis ruled out on a positron emission tomography (PET) scan.

Impact of Fasting Lipid Profile on Chronic Kidney Disease Patients Having Fatty Liver Disease.

Background and objectives Chronic kidney disease (CKD) share a common pathophysiology with non-alcoholic fatty liver disease (NAFLD). This study aims to identify the lipid derangements in patients of CKD and to associate them with radiological evidence of NAFLD. Material and methods A cross-sectional observational study was performed in a tertiary care hospital, to include all chronic kidney disease patients (n=238) through non-probability consecutive sampling. The criteria for inclusion were baseline estimated Glomerular filtration rate (eGFR) below 60 ml/min/1.73m2 for at least three months and chronic renal parenchymal changes on ultrasound. Two study groups were identified based on ongoing hemodialysis, while two further study groups were identified based on radiological evidence of fatty liver disease. Results The mean age of the study population was 48.52 ± 9.44 years with no difference amongst hemodialysis status, females elder than males (p= 0.027), those with fatty liver were much younger (p=0.014), and the most common age group below 50 years (p=0.005) among the fatty liver group. Radiological evidence of NAFLD was found amongst two-third of the study group with the status of hemodialysis indifferent among the study population (p=0.436). The mean values amongst fatty liver versus non-fatty liver groups revealed high creatinine, alanine transaminase (ALT), high-density lipoprotein (HDL), triglycerides (TG), and very-low-density lipoprotein (VLDL) in the fatty liver group, low-density lipoprotein (LDL) and total cholesterol (TC) were indifferent amongst the groups, while LDL/HDL ratio was higher in the non-fatty liver group. Conclusion A significantly higher HDL was found in fatty liver associated with CKD as compared to the non-fatty liver group.

Role of Biochemical Markers in Invasive Ventilation of Coronavirus Disease 2019 Patients: Multinomial Regression and Survival Analysis.

Background and objectives Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the pathogen responsible for the coronavirus disease 2019 (COVID-19) pandemic. The disease mainly affects the respiratory system of the patient, in particular, the lungs, which leads to patients presenting with acute respiratory distress syndrome and acute respiratory failure, with 5-15% of patients requiring observation in the intensive care unit (ICU) with respiratory support in the form of ventilation. This study was aimed at identifying the role of biochemical markers in the risk stratification of invasive and non-invasive ventilation of hospitalized COVID-19 patients. Materials and methods The study was conducted as a prospective, observational study of all admitted COVID-19 patients. A comparative analysis was performed of the survivors who were on invasive versus (vs) non-invasive ventilation and the non-survivors similarly. After computing the descriptive statistics, a multinomial logistic regression model was applied to obtain an unadjusted odds ratio (OR) at 95% confidence interval (CI), with Hosmer-Lemeshow (HL) goodness-of-fit test used to predict the fitness of the data. Kaplan-Meier survival curves were obtained for each of the laboratory investigations predicting survival along with the intensive care stay and invasive ventilation. A log-rank test was carried out to compare the survival distributions. Results A total of 373 included patients in the study had a mean age of 52.78 ± 15.76 years with females younger than males, and indifference amongst invasive vs non-invasively ventilated (p=0.821). Females were slightly more prone to invasive ventilation (p=0.097). Overall, 39% of the subjects did not need respiratory support, while 13% were on a ventilator, 16% on bilevel positive airway pressure/continuous positive airway pressure (BiPAP/CPAP), and 31% on supplemental oxygen therapy. Among the laboratory markers, mean hemoglobin was evidently lower in the invasive group, leukocytosis and thrombocytopenia were present in both invasively ventilated and non-surviving patients, while neutrophilia and lymphocytopenia were statistically indifferent among the mode of ventilation. Elevated urea, creatinine, and sodium were also significantly deranged laboratory markers amongst the invasively ventilated group. C-reactive protein (CRP) and lactate dehydrogenase (LDH) were elevated significantly in the invasive group, while serum ferritin was more frequently raised in the non-invasively ventilated group. Procalcitonin (PCT) was significantly associated with invasive ventilation as opposed to the non-invasive group. D-dimer was equally raised in both the groups at admission but significantly elevated in the invasive group at discharge. A multinomial regression model signified D-dimer (OR: 16.301), hypernatremia (OR: 12.738), creatinine (OR: 12.589), urea (OR: 12.576), and LDH (OR: 12.245) most significantly associated with death, while those for invasive ventilation were D-dimer (OR: 8.744), hypernatremia (OR: 4.532), PCT (OR: 3.829), neutrophilia (OR: 3.804), leukocytosis (OR: 3.330), and serum urea (OR: 3.312). Kaplan-Meier curves conclude total leucocyte count (TLC), neutrophils, lymphocytes, urea, creatinine, sodium, CRP, LDH, PCT, and D-dimer all significantly contributing to an early death. Conclusion The most significant marker for mortality was D-dimer, followed by serum sodium, urea/creatinine, LDH, ICU stay, and invasive ventilation.

Poor Prognostic Biochemical Markers Predicting Fatalities Caused by COVID-19: A Retrospective Observational Study From a Developing Country.

Background and objectives Infections with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are rapidly spreading, posing a serious threat to the health of people worldwide, resulting in the World Health Organization officially declaring it a pandemic. There are several biochemical markers linked with predicting the severity of coronavirus disease. This study aims to identify the most effective predictive biomarker such as C-reactive protein (CRP), ferritin, lactate dehydrogenase (LDH), procalcitonin (PCT), and D-dimer, among others, in predicting the clinical outcome of the disease. Materials and methods This study was conducted as a retrospective, observational, multi-centric study, including all admitted COVID-19 positive patients only. The disease outcome was followed along with the hospital course of every patient at the time of analysis. Baseline laboratory investigations of all patients were monitored both at admission and discharge. A comparative analysis was done between the survivors (n=263) and non-survivors (n=101). Statistical analysis was conducted using IBM SPSS Statistics for Windows Version 25 (Armonk, NY: IBM Corp.). Results Of 364 patients, 65.7% were in the isolation ward, and 34.3% were in the intensive care unit; 72.3% of patients survived, while 27.7% of patients died. The mean age of the study population was 52.6 ± 15.8 years with female patients significantly younger than male patients (p=0.001) and 50 to 75 years being the most common age group (p=0.121). Among the survivors versus non-survivors of COVID-19, there were significant differences in total leukocyte count (p<0.001), neutrophil count, (p<0.001), lymphocyte count (p<0.001), urea (p<0.001), serum bicarbonate (p=0.001), CRP levels (p<0.001), LDH (p=0.013), and D-dimer (p<0.001) at admission. At discharge, the laboratory values of non-surviving patients showed significant leukocytosis (p<0.001), neutrophilia (p<0.001), lymphocytopenia (p<0.001), decreased monocytes (p<0.001), elevated urea and creatinine (p<0.001), hypernatremia (p<0.001), decreased serum bicarbonate levels (p<0.001), elevated CRP level (p=0.040), LDH (p<0.001), ferritin (p=0.001), and D-dimer (p<0.001). Among the recovered patients, the laboratory investigations at admission were significantly different from those at discharge like increased platelets (p=0.007), lower neutrophil count (p=0.001), higher lymphocyte count (p=0.005), an improved creatinine (p=0.020), higher sodium (p=0.008), increased bicarbonate levels (p<0.001), decreased CRP levels (p<0.001), and a lower LDH (p=0.039). However, the laboratory values of non-surviving patients had shown a lower hemoglobin (p=0.016), increased mean cell volume (p<0.001), significantly increased total leukocyte count (p<0.001), increased urea and creatinine (p<0.001), hypernatremia (p<0.001), increased bicarbonate (p=0.025), elevated D-dimer levels (p=0.043), and elevated PCT (p=0.021) on discharge. Receiver operating characteristic analysis concluded LDH (area under the curve [AUC]: 0.875), D-dimer (AUC: 0.803), and PCT (AUC: 0.769) were superior biomarkers to ferritin (AUC: 0.714) and CRP (AUC: 0.711) in predicting the fatality of COVID-19. Conclusion Inflammatory markers are a useful guide for predicting mortality, and the study results concluded that LDH, PCT, D-dimer, CRP, and ferritin were effective biomarkers.

Clinical Profiles, Characteristics, and Outcomes of the First 100 Admitted COVID-19 Patients in Pakistan: A Single-Center Retrospective Study in a Tertiary Care Hospital of Karachi.

Background and objective COVID-19 is a highly disseminating viral disease imparted by severe acute respiratory syndrome coronavirus 2 (SARS-COV-2), which was declared a global pandemic by the World Health Organization. In our study, we aimed to describe the clinical characteristics of the first 100 hospitalized patients of confirmed COVID-19 in a developing country. Materials and methods The study included all the admitted patients (n = 100) having COVID-19 polymerase chain reaction (PCR) positive, and evaluated clinical profiles and characteristics of the patients linking to disease severity. Results Out of the 100 patients, 67 were in the ward, 33 were in ICU, 78 of them recovered, while 22 deaths reported. The mean age was 52.58 ± 15.68, with most frequent comorbidities are diabetes and hypertension while frequent symptoms are fever and dry cough. Bilateral lower zone patchy infiltrates are frequent chest radiographic findings. Amongst the patients admitted in ICU, there were significant differences in the total leukocyte count (P = 0.001), neutrophils and lymphocytes (P =< 0.001), monocytes (P = 0.027), urea (P =< 0.001), creatinine (P = 0.002), neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) increasing with disease severity, lymphocyte-to-monocyte ratio (LMR) and lymphocyte-to-C-reactive protein ratio (LCR) decreasing with mortalities. Gamma-glutamyl transferase (GGT) followed by aspartate aminotransferase (AST) are frequent hepatic derangements, while C-reactive protein (CRP) levels predicting ICU admission with area under the curve (AUC): 0.806, positive predictive value (PPV): 85.1% and lactate dehydrogenase (LDH) predicting mortality with AUC: 0.877, PPV: 97.3%, while NLR (AUC: 0.806, PPV: 95.8%) for mortality and neutrophils (AUC: 0.773, PPV: 87.5%) for ICU patients. Conclusion A number of factors are linked with disease severity and mortality along with dynamic changes of the laboratory investigations during hospital stay affecting prognosis.
