Prevalence of Pulmonary Hypertension in Liver Cirrhosis Patients: A Cross-Sectional Analytical Study.

BACKGROUND: Liver cirrhosis (LC) is a common complication of chronic liver disease. Its prevalence has increased markedly over the last few years. With liver cirrhosis comes cardiovascular morbidity and mortality. It is important that the detection of the abnormalities by echocardiography be given priority, as this can change the clinical outcome of these patients with cardiovascular abnormalities in liver cirrhosis. AIM: This study aims to determine the prevalence of pulmonary hypertension in LC patients. METHODS AND MATERIALS: A cross-sectional analytical study was carried out at JUTH (Jos University Teaching Hospital) over a period of one year. We recruited 210 adult patients with liver cirrhosis from the gastroenterology clinic and wards for this study. Data from these patients were collected with questionnaires administered by the interviewer and analysed using SPSS 23 statistical software (IBM Corp., Armonk, NY). The data obtained are presented in tables and charts. Categorical variables were expressed as proportions and frequencies, while continuous data were expressed as the median, mean, and standard deviation. RESULTS: Pulmonary hypertension was found in 30.5% of the participants, with mild pulmonary hypertension being the most common. No one had severe pulmonary hypertension. There was an increased risk of developing pulmonary hypertension in patients with coughs, easy fatigability, bilateral leg swelling, abdominal swelling, and ascites (P<0.05). CONCLUSION: The result showed that there is a high prevalence of pulmonary hypertension in patients with liver cirrhosis.

Echocardiographic Assessment of Right Ventricular Function in Patients With Liver Cirrhosis.

BACKGROUND: In patients with chronic liver disease, the common endpoint of its course is liver cirrhosis which is a cause of cardiovascular morbidity and mortality. These abnormalities in the cardiovascular system, especially the heart, can be detected by echocardiography. Identifying and acting on these abnormalities can have an impact on their management thereby reducing morbidity and mortality of patients with liver cirrhosis. The aim of this study was to determine the prevalence of right ventricular systolic and diastolic dysfunction in liver cirrhosis patients. METHODS AND MATERIALS: A hospital-based cross-sectional study was conducted among adult patients of the gastroenterology unit (ward and clinic) diagnosed with liver cirrhosis. A total of 243 patients were recruited and 210 were evaluated for this study. This study was carried out over one year. Cardiology studies, including electrocardiography and echocardiography, were conducted on patients to assess right ventricular function. RESULTS: Among the participants, 44.8% had right ventricular hypertrophy and 3.8% had right ventricular dilatation. Using Tricuspid Annular Plane Systolic Excursion (TAPSE), 17.1% were found to have right ventricular systolic dysfunction and 51.4% had systolic dysfunction using FAC. Diastolic dysfunction was found in 61% of the participants and grade 2 diastolic dysfunction was the commonest. CONCLUSION: From this study, a high prevalence of right ventricular systolic and diastolic dysfunction was recorded among patients with liver cirrhosis.

Cardiac Abnormalities in Relation to the Disease Activity Index Among Systemic Lupus Erythematosus Patients in a Tertiary Hospital: A Cross-Sectional Study.

BACKGROUND:  Systemic lupus erythematosus (SLE) is a multisystem autoimmune connective tissue disorder involving multiple organs and systems. Cardiovascular involvement in SLE patients is a major cause of morbidity and mortality. Although subclinical cardiac abnormalities exist among SLE patients, they are rarely screened for. Echocardiography has been demonstrated to be a useful tool for the early diagnosis of cardiac abnormalities in SLE patients, many of which are clinically silent. Early recognition of cardiovascular abnormalities is vital for the prompt initiation of the appropriate management. This study aims to determine the prevalence of various structural and functional cardiac abnormalities among SLE patients and to determine its association with the modified SLE Disease Activity Index 2000 (modified SLEDAI-2K). METHODS:  The study was a cross-sectional study of SLE patients at the Korle-Bu Teaching Hospital (KBTH), Accra, Ghana, from June to December 2021. The setting was the rheumatology outpatient clinic of the KBTH and included adult men and women, 18 years and above, diagnosed with SLE with no known cardiac abnormalities. The baseline demographic and clinical characteristics of the participants were determined. A detailed transthoracic echocardiogram was performed for all patients. The frequency of common cardiac pathologies was determined and compared between those with a high modified SLEDAI-2K and those with a low modified SLEDAI-2K. RESULTS:  Ninety-nine SLE patients participated in the study with a mean age of 35.12 years. Females formed the majority (90.9%) of the participants. The mean age at diagnosis of SLE was 28.7 years and the mean disease duration was 4.6 years. All of the participants were on at least two disease-modifying medications. The mean modified SLEDAI-2K score was 9.1. Thirty-five percent (35%) of the patients had mild to moderately active disease and 39% had severely active disease. Sixty-six (66%) out of the severely active disease group had abnormal echocardiographic findings, while 28% of those with mild to moderate disease had abnormal echocardiographic findings. Echocardiographic abnormalities were found in 56 patients (47%), out of which 8.7% had valvular involvement, 15.7% had diastolic dysfunction, 5.2% had left ventricular hypertrophy (LVH), and 0.9% had left ventricular systolic dysfunction (LVSD). About 12% of the participants had pulmonary hypertension and 1% had pericardial involvement. The odds of echocardiographic abnormalities were 13.7 times higher in SLE patients with high disease activity compared to those with low disease activity (odds ratio (OR) = 13.714, 95% confidence interval (CI) = 3.804-49.442, p < 0.001). There was no significant association between cardiac abnormalities and SLE duration. No significant correlation between cardiac abnormalities and modified SLEDAI-2K score was found.  Conclusion: Cardiac abnormalities, especially left ventricular diastolic dysfunction (LVDD), valvular involvement, and pulmonary hypertension, are common in SLE patients. For SLE patients, especially those with active diseases, echocardiographic assessment should be considered in the management of SLE patients to enable early detection of cardiac abnormalities, early treatment, and thus a decrease in morbidity and mortality associated with cardiovascular involvement in SLE patients.

A Diagnostic Dilemma: A Case of Neurosarcoidosis Without Systemic Sarcoidosis.

Sarcoidosis is a multisystem granulomatous disorder of unknown etiology characterized by non-caseating granulomas in involved organs. Approximately 10% of patients with sarcoidosis exhibit central nervous system involvement. However, the occurrence of isolated neurosarcoidosis without concurrent systemic signs is very rare, affecting less than 1% of patients. We report a case of isolated neurosarcoidosis in a previously healthy patient who initially presented with a single episode of seizure and loss of consciousness. Brain MRI showed T2/fluid-attenuated inversion recovery (FLAIR) hyperintense extra-axial soft tissue mass over the left cerebral convexity measuring approximately 14 mm in maximum depth. Excisional biopsy of the brain mass showed chronic non-caseating granulomatous inflammation with epitheloid cells that was consistent with sarcoidosis. Treatment with high dose-steroids led to significant clinical improvement. At a two-year follow-up, there were no signs of systemic disease or recurrence of the meningeal mass. This case emphasizes the rarity of such presentation, diagnostic difficulties, and the importance of high suspicion and timely management to prevent debilitating neurologic complications.

Procedural safety of transcatheter aortic valve replacement with Portico valve: a systematic review.

BACKGROUND: The Portico transcatheter aortic heart valve is a self-expandable, fully resheathable bioprosthetic valve with a nitinol frame and porcine pericardial sealing cuff. It has been used among symptomatic severe aortic stenosis (AS) who are at high or extreme surgical risk. However, till date very few studies has been reported with inconclusive evidence for its postprocedure safety outcomes. OBJECTIVE: The authors aim to evaluate the safety of the Portico transcatheter aortic valve replacement system among patients with AS. METHODOLOGY: The authors conducted a systematic literature search on PubMed, Embase, and Scopus from inception till 10th April 2023 by using predefined MESH terms using 'AND' and 'OR'. The following search terms were used: 'Aortic Stenosis' AND 'Transcatheter aortic valve replacement' OR 'Portico valve'. Finally, descriptive statistics were used to summarize the data in this paper. The mean and SD were adopted to describe continuous variables, whereas frequencies and percentages were used for dichotomous data. RESULTS: A total of 7 studies with 2782 patients were included in the analysis. The mean age of patients was 82.3 years, and 54.63% were female. The most common comorbidity was hypertension (65.21%) and diabetes mellitus (26.45%). Among patients of AS with Portico valve implants, postprocedural outcomes including 30-day mortality (2.32%), cardiovascular mortality (2.37%), stroke (2.23%), myocardial infarction (0.94%), major bleeding (3.97%), major vascular complications (4.91%), acute kidney injury (1.37%), and permanent pacemaker implantations in 15.73% patients were reported. Overall, device success was observed in 95.82% of patients. CONCLUSION: Transcatheter aortic valve replacement with the repositionable Portico valve, a new bioprosthesis, appears to have a low postprocedural mortality rate and other clinical outcomes in high-risk patients with severe AS.

Demographics and outcomes of hemoglobin genotype in hospitalized patients with COVID-19 and sickle cell disease in the United States.

INTRODUCTION: Coronavirus disease 2019 (COVID-19) is associated with poor outcomes in sickle cell disease (SCD) patients. However, there is a paucity of data comparing hemoglobin (Hb) genotypes in SCD and infection outcomes. METHODS: The National Inpatient Sample was used to identify the record of hospitalizations with COVID-19 and SCD in 2020 using the International Classification of Disease, Tenth Revision codes. Study outcomes (invasive mechanical ventilation, extracorporeal membrane oxygenation, shock, vasopressor use, measures of resource utilization, and in-hospital mortality) were compared between hemoglobin SS, SC, and S-beta thalassemia (Sß). RESULTS: Of the 102 975 COVID-19 hospitalizations with SCD, 87.26% had HbSS, 7.16% had HbSC, and 5.58% had HbSß. Younger patients were more likely to have HbSS, while older patients were likely to have HbSC and HbSß. HbSS was more frequent with Blacks, while HbSß was more prevalent with Whites and Hispanics. Though measures of resource utilization were higher in HbSS, there was no significant difference in in-hospital outcomes between the three genotypes. CONCLUSION: There is no difference in COVID-19 outcomes among Hb genotypes in SCD. Further studies are needed to explore the reasons for this observation.

Cardiac Dimensions in Normal Pregnancy: A Prospective Study.

BACKGROUND: Pregnancy, a unique physiologic state, is associated with several changes in the various body systems. The cardiovascular system is one of the systems affected, with chronic volume overload being one of the characteristic changes experienced during pregnancy. Cardiovascular disease in pregnancy is the leading cause of non-obstetric maternal death worldwide. AIM: This study aims to determine and describe the changes in left and right ventricular and atrial sizes in systole and diastole in the course of normal pregnancy. METHODS AND MATERIALS: A cohort study was conducted among healthy pregnant women between the age of 18 and 40 who attended the antenatal clinic of Federal Medical Centre (FMC), Yenagoa, Bayelsa State. Fifty women were recruited during the first trimester (T1) of pregnancy and followed up until six weeks postpartum. Ethical approval was obtained from the Research Ethics Committee of Federal Medical Centre, Yenagoa, with approval number FMCY/REC/ECC/2019/JAN/150. Clinical evaluation, hematologic, biochemical, and anthropometric assessments, and two-dimensional M-mode and Doppler echocardiography were done for the participants in each trimester of pregnancy and at six weeks postpartum. The clinical and echocardiographic parameters were analyzed using Statistical Package for the Social Sciences (SPSS) version 22.0 (IBM Corp., Armonk, NY, USA). RESULTS: The mean trend of left ventricular posterior wall thickness in diastole (LVPWd) and left ventricular posterior wall thickness in systole (LVPWs) increased progressively from the first to third trimester (T3) (not statistically significant) but dropped toward initial values in postpartum to the level that was statistically significant for LVWPd alone when compared to baseline first trimester values. The left atrial diameter in systole (LADs) was largest in the third trimester, and the left atrial volume index (LAVI) and right ventricular basal diameter (RVD1) also showed a similar trend. The left ventricular internal diameter (LVID) in both systole and diastole increased progressively from the first to the third trimesters, but the increase was only statistically significant between the third trimester (T3) and the first trimester (T1). The right atrial diameter (RAD) and right atrial volume (RAV) also increased progressively from the first to the third trimesters, but the increase was only statistically significant between the third trimester (T3) and the first trimester (T1). CONCLUSION: Changes were noticed in the cardiac chamber sizes during pregnancy. However, this reversed back to levels similar to the first trimester during the postpartum period. To aid in the early detection and treatment of cardiovascular disorders in pregnancy, screening of apparently healthy pregnant women who later developed complaints is advised as cardiovascular changes could be significant during pregnancy.

Clinical and Echocardiographic Correlates of Iron Status in Chronic Heart Failure Patients: A Cross-Sectional Descriptive Study.

BACKGROUND:  Chronic heart failure (HF) is one of the conditions commonly seen in the medical outpatient departments, and iron deficiency (ID) has been reported as the commonest nutritional deficiency in these patients. The presence of ID may interfere with the clinical parameters of chronic HF. The relationship between iron status and chronic HF needs more attention and should be given more consideration in the evaluation of patients with chronic HF. AIM: The aim of the study was to determine the relationship, if any, between iron status and clinical/echocardiographic variables in chronic HF. METHODS AND MATERIALS: A cross-sectional descriptive study was carried out at the Lagos University Teaching Hospital (LUTH), Nigeria, where 88 patients with chronic HF were recruited to participate in this study. The participants underwent clinical and laboratory assessments. Iron status was assessed with full blood count parameters; serum ferritin and transferrin saturation (Tsat) and its relationship with clinical parameters among these participants were also studied. RESULTS: No correlations existed between the duration of chronic HF and iron status when compared using Tsat. However, a significant weak negative correlation was observed between the duration of HF and the serum ferritin levels. The clinical characteristics of the HF participants with and without ID were compared. There was no significant difference in the frequency of prior hospitalization in both groups. However, a higher proportion of participants with severe HF (New York Heart Association (NYHA) classes III/IV) (n = 14; 46.7%) were iron-deficient compared to those with moderate chronic HF (NYHA II) (n = 11; 36.7%). This relationship was statistically significant. Left ventricular ejection fraction (LVEF) was similar in the iron-deficient and iron-replete groups (using serum ferritin or Tsat) both when compared as means and when compared after categorizing LVEF as HF with preserved ejection fraction (HFpEF) vs HF with reduced ejection fraction (HFrEF). There was no statistically significant correlation between the severity of ID and LVEF.  Conclusion: A spectrum of clinical changes occurs in patients with chronic HF. ID can make these changes more profound and the condition less amenable to standard HF treatments. These patients may therefore benefit from further evaluation for this nutritional deficiency. Laboratory measurements including Tsat and serum ferritin may help in further assessment of select patients with worse and/or non-responsive clinical parameters.

Sudden-Onset Sensorineural Hearing Loss and Tinnitus in a Patient With Rheumatoid Arthritis: A Case Report and Literature Review.

Rheumatoid arthritis (RA) can affect the auditory system either as a direct complication of the disease course or secondary to medication adverse effects. Rheumatoid arthritis-induced autoimmune inner ear disease can present as tinnitus, conductive hearing loss, sensorineural hearing loss (SNHL), or mixed. According to previously published articles, SNHL is the most common hearing loss in RA. Age, smoking, noise exposure, and alcohol may affect the disease progression. Here, we present a case of a 79-year-old female who presented to the rheumatology clinic with complaints of abrupt onset bilateral hearing loss with associated tinnitus; pure tone audiometry confirmed sensorineural hearing loss. Her tinnitus resolved completely, and her hearing improved significantly after treatment with steroids and leflunomide. Based on this case and previous literature, we conclude that rheumatoid arthritis is the cause of SNHL in our patient. Appropriate and timely medical interventions have been reported to improve the prognosis of hearing impairment in rheumatoid arthritis patients. Our case highlights the need to have a high index of suspicion of rheumatoid arthritis-induced autoimmune inner ear disease in an elderly patient presenting with sudden-onset hearing impairment and the importance of prompt referral to a rheumatologist.

Outcomes of COVID-19 hospitalizations in patients with sickle cell disease: A nationwide analysis.

INTRODUCTION: There is a paucity of data on the outcomes of coronavirus disease 2019 (COVID-19) in patients with sickle cell disease (SCD) in the United States. We examined the outcomes of patients with COVID-19 and SCD. METHODS: We utilized the National Inpatient Sample (NIS) to identify the data of patients diagnosed with COVID-19 and SCD in 2020 using the International Classification of Disease, Tenth Revision codes. In-hospital outcomes (invasive mechanical ventilation and mortality) were compared between SCD and non-SCD groups. RESULTS: Of the 1 057 550 COVID-19 hospitalizations, 2870 (0.3%) had SCD. The median age of the SCD group was 42 (IQR: 31) vs. 66 (IQR: 23) in the non-SCD group (p < .0001). Patients with SCD were likely to be females (62.02% vs. 37.98%, p < .0001), Blacks (87.81% vs. 12.19%, p < .0001), and in the lowest income quartile (50.62% vs. 11.15%, p < .0001). There was no difference in the outcomes between the two groups. There were increased odds of invasive mechanical ventilation and in-hospital mortality in COVID-19 in Asians, Hispanics, Native Americans, and Blacks (except for in-hospital mortality) compared to Whites. CONCLUSION: In-hospital mortality and invasive mechanical ventilation outcomes in SCD are comparable to that in non-SCD patients hospitalized with COVID-19.

Examining Disparities in Ownership and Use of Digital Health Technology Between Rural and Urban Adults in the US: An Analysis of the 2019 Health Information National Trends Survey.

BACKGROUND: Although research shows that digital health tools (DHT) are increasingly integrated with healthcare in the United States, very few studies have investigated the rural-urban differences in DHT adoption at the national level. Individuals in rural communities experience disproportionately greater rates of chronic diseases and face unique challenges in accessing health care. Studies have shown that digital technology can improve access and support rural health by overcoming geographic barriers to care. OBJECTIVE:  To evaluate the rates of ownership and preferences for utilization of DHT as a measure of interest among rural adults compared to their urban counterparts in the United States using a National Inpatient Survey. METHODS:  Data was drawn from the 2019 (n= 5438) iteration of the Health Information National Trends Survey (HINTS 5 cycle 3). Chi-square tests and weighted multivariable logistic regressions were conducted to examine rural-urban differences regarding ownership, usage, and use of digital health tools to interact with health care systems while adjusting for health-related characteristics and sociodemographic factors. RESULTS: The ownership rates of digital health technology (DHT) devices, including tablets, smart phones, health apps, and wearable devices, were comparable between rural and urban residents. For tablets, the ownership rates were 54.52% among rural residents and 60.24% among urban residents, with an adjusted odds ratio (OR) of 0.87 (95% confidence interval {CI}: 0.61, 1.24). The ownership rates of health apps were 51.41% and 53.35% among rural and urban residents, respectively, with an adjusted OR of 0.93 (95% CI: 0.62, 1.42). For smartphones, the ownership rates were 81.64% among rural residents and 84.10% among urban residents, with an adjusted OR of 0.81 (95% CI: 0.59, 1.11). Additionally, rural residents were equally likely to use DHT in managing their healthcare needs. Both groups were equally likely to have reported their smart device as helpful in discussions with their healthcare providers (OR 0.90; 95% CI 63 - 1.30; p = 0.572). Similarly, there were similar odds of reporting that DHT had helped them to track progress on a health-related goal (e.g., quitting smoking, losing weight, or increasing physical activity) (OR 1.17; 95% CI 0.75 - 1.83; p = 0.491), and to make medical decisions (OR 1.05; 95% CI 0.70 - 1.59; p = 0.797). However, they had lower rates of internet access and were less likely to use DHT for communicating with their healthcare providers. CONCLUSION:  We found that rural residents are equally likely as urban residents to own and use DHT to manage their health. However, they were less likely to communicate with their health providers using DHT. With increasing use of DHT in healthcare, future research that targets reasons for geographical digital access disparities is warranted.

Trends of Cardiovascular Interventions Stratified by Body Mass Index: An Analysis of the 2016-2020 Nationwide Inpatient Sample Population.

Background There is a scarcity of studies delineating the trends of cardiovascular interventions in the hospitalized population stratified by body mass index (BMI). Our study aimed to study the burden of cardiovascular interventions and outcomes by BMI. Methods We retrospectively analyzed the Nationwide Inpatient Sample (NIS) database between January 2016 and December 2020. We identified the population of interest using the International Classification of Diseases, Tenth Revision (ICD-10) code. We studied the BMI in five categories: "healthy weight" (HW; BMI < 19.9-24.9 kg/m2), "overweight" (OV; BMI = 25-29.9 kg/m2), "obesity class one" (OB1; BMI = 30-34.9 kg/m2), "obesity class two" (OB2; BMI = 35-39.9 kg/m2), and "obesity class three" (OB3; BMI > 40 kg/m2). Results There were 5,654,905 hospitalizations with an ICD-10 code related to BMI within this study period. The HW group had 1,103,659 (19.5%) hospitalizations, the OV group had 462,464 (8.2%), the OB1 group had 1,095,325 (19.4%), the OB2 group had 1,036,682 (18.3%), and the OB3 group had 1,956,775 (34.6%) hospitalizations. The mean age of the population with obesity was as follows: OB1 = 61 years (SD = 16); OB2 = 58 years (SD = 15.9); and OB3 = 55 years (SD = 15.5). The mean ages of the HW and OV groups were 68 years (SD = 16.6) and 65 years (SD = 16.1), respectively. In the HW group, there were 948 (8.1%) hospital admissions for aortic valve replacement (AVR), 54 (11%) for aortic valve repair (AVRr), 737 (15.9%) for mitral valve replacement (MVRr), 12 (17.1%) for mitral valve repair (MVR), 79 (2.2%) for left atrial appendage (LAA) closure, and 3390 (5.2%) for percutaneous coronary intervention (PCI). The OV group had 1049 (8.9%) hospital admissions for AVRs, 42 (9%) for AVRr, 461 (10%) for MVRr, four (5.7%) for MVR, 307 (8.6%) for LAA closure, and 5703 (8.8%) for PCIs. The OB1 group had 3326 (28.4%) hospital admissions for AVR, 125 (26.9%) for AVRr, 1229 (26.7%) for MVRr, 23 (32.9%) for MVR, 1173 (32.9%) for LAA, and 20,255 (31.3%) for PCI, while the OB2 group had 2725 (23.3%) hospital admissions for AVR, 105 (22.6%) for AVRr, 898 (19.4%) for MVRr, 11 (15.7%) for MVR, 933 (26.2%) for LAA, and 16,773 (25.9%) for PCI. Lastly, the OB3 group had 3626 (31%) hospital admissions for AVR, 139 (29.9%) for AVRr, 1285 (27.8%) for MVRr, 20 (28.6%) for MVR, 1063 (29.9%) for LAA, and 18,589 (28.7%) for PCI. Conclusion Our study supports the evidence of increased cardiovascular interventions with increasing BMI. Albeit, an inconsistent presentation across the spectrum of cardiovascular diseases and outcomes, for example, equal or better outcomes in obese cohorts compared to the healthy weight population undergoing PCI. However, the increasing cardiovascular intervention burden in the youngest studied population suggests a rise in the cardiovascular disease burden among the young and partially explains their better outcomes. Steps to include weight management for these patients are paramount.

Assessing Iron Status in Chronic Heart Failure Patients by Using Serum Ferritin and Transferrin Saturation Levels: A Cross-Sectional Descriptive Study.

Background and objective Chronic heart failure (HF) is a major medical condition worldwide and is associated with significant morbidity and mortality. Chronic HF could be complicated by iron deficiency (ID), and in severe cases, ID anemia, leading to negative HF outcomes even in people on optimal HF treatments. ID has been reported to be the most common nutritional deficiency in chronic HF. It is therefore important to study and analyze the relationship between these two variables. Identifying and treating the comorbidity of ID in chronic HF may help improve the treatment outcomes of chronic HF. In this study, we aimed to determine the iron status of chronic HF patients by using serum ferritin (SF) and transferrin saturation (TSAT). Materials and methods A cross-sectional descriptive study was conducted involving 88 Nigerian patients with chronic HF at the Lagos University Teaching Hospital (LUTH). The participants were evaluated based on their laboratory findings. Results ID was found in 34% of chronic HF patients. Of them, 17% had absolute ID while 17% had functional ID. Conclusion ID was present in about one-third of the chronic HF patients. It was more common and worse in patients belonging to advanced HF functional classes.

Model for End Stage Liver Disease (MELD) Score: A Tool for Prognosis and Prediction of Mortality in Patients With Decompensated Liver Cirrhosis.

BACKGROUND: Decompensated liver disease has become a common occurrence in medical wards. It has become the third most common cause of death in medical wards. This high mortality rate has become a matter of concern. It is important that a reliable scoring system helps to stratify patients with liver cirrhosis who will require liver transplantation. OBJECTIVE: To determine the value of the Model for End-Stage Liver Disease (MELD) score in assessing the mortality of patients with decompensated liver cirrhosis over one month period (30 days). METHODS AND MATERIALS: A longitudinal study was conducted. A total of 110 patients diagnosed with decompensated liver cirrhosis were recruited from the gastroenterology clinic and medical wards of the University of Benin Teaching Hospital (UBTH), Benin City. The patients were recruited consecutively and met the inclusion criteria for the study. Demographic data, history, clinical, biochemical, ultrasonographic, and liver biopsy findings were evaluated in the patients who participated in this study.  Results: The mean age of the patients was 57 ± 11.06 years. Out of the 110 study participants, a 2.9:1 male-to-female ratio was appreciated in the patient population, with a total of 82 males and 28 females. Multiple logistic regression analysis identified MELD scores as an independent predictor of mortality in the studied patients. Predictive values of the MELD score for 1-month mortality which was analyzed using the receiver operating characteristic (ROC) curves showed that the MELD score had a sensitivity of 72.2% and positive predictive value of 93.6% with an area under the curve of 0.926 for all-cause mortality among decompensated liver cirrhosis patients. CONCLUSION: MELD score is a good predictor of mortality among patients with decompensated liver cirrhosis over a 1-month (30 days) period.

Malignant Pleural Effusion As the Initial Presentation of Renal Cell Carcinoma: A Case Report and Literature Review.

Renal cell carcinoma is the most common renal neoplasm. Its presentation is often very occult, and it may be discovered incidentally. It may present with the classic symptoms of back pain, flank pain, hematuria, or hypertension. Renal cell carcinoma may also present with malignant pleural effusion at diagnosis; however, it is very rare. In this case report and literature review, we describe a 77-year-old male who was diagnosed with renal cell carcinoma after presenting with a malignant pleural effusion - an extremely rare phenomenon. An analysis of the literature yielded 13 case reports, including ours, where the diagnostic presentation of renal cell carcinoma was a malignant pleural effusion. Our patient presented with left-sided chest pain. Imaging was suggestive of pleural effusion. CT and MRI imaging demonstrated masses in the upper and lower poles of the right kidney suggestive of renal cell carcinoma. CT imaging also showed lung nodules that were suggestive of pulmonary metastases. Biopsy and immunostaining of pleural tissue were positive for clear cell renal cell carcinoma. Therapeutic thoracentesis was performed. Despite this, the patient developed recurrent large-volume pleural effusions requiring drainage and placement of a pleural catheter. Our patient's extremely rare presentation of malignant pleural effusion as the diagnostic presentation of renal cell carcinoma along with recurrent, large-volume effusions requiring drainage has only been reported in the form of case reports in the literature.

Diagnostic and Therapeutic Challenges of Concurrent Intracranial Hemorrhage and Cerebral Venous Thrombosis in a Patient With Acute Lymphoblastic Leukemia: A Case Report and Literature Review.

Cerebral venous sinus thrombosis (CVST) is a cerebrovascular condition due to the thrombosis of cerebral venous sinuses, leading to intracranial hemorrhage, increased intracranial pressure, focal deficit, seizure, toxic edema, encephalopathy, and death. The diagnosis and therapeutic approach of CVST remain challenging because of its highly nonspecific clinical presentation including headaches, seizures, focal neurologic deficits, and altered mental status, etc. Anticoagulation is the mainstay of CVST treatment and should be started as soon as the diagnosis is confirmed. Here, we present the case of a 34-year-old male construction worker who presented to the emergency department with a complaint of right chest wall pain and swelling. He was admitted to the hospital following a diagnosis of anterior chest wall abscess and mediastinitis. During hospitalization, his complete blood count revealed pancytopenia with blast cells, and bone marrow biopsy revealed 78.5% lymphoid blasts by aspirate differential count and hypercellular marrow (100%) with decreased hematopoiesis. He developed concurrent CVST and intracranial hemorrhage while receiving CALGB10403 (vincristine, daunorubicin, pegaspargase, prednisone) with intrathecal cytarabine induction chemotherapy for acute lymphoblastic leukemia (ALL). The patient failed two standard chemotherapy for ALL and achieved remission while on third-line chemotherapy with an anti-CD19 monoclonal antibody, blinatumomab. Although this patient had an MRI scan of the brain with multiple follow-up non-contrast CT scans, it was CT angiography that revealed CVST. This showed the diagnostic challenge in CVST, with CT and MRI venography having excellent sensitivity in diagnosing CVST. Risk factors for CVST in our patient were ALL and its intensive induction chemotherapy with pegaspargase.

Optimizing Nutrition in Renal Patients: Effects of a Low-Protein Diet Supplemented With Ketoacids.

Background Chronic kidney disease (CKD) is a non-communicable disease; it is a major cause of morbidity and mortality in Nigeria as the incidence has been increasing in Nigeria over the last few years. A low-protein diet supplemented with ketoacids has been duly documented to reduce the malnutrition associated with CKD as well as improve estimated glomeruli filtration rate while delaying the onset of dialysis in predialysis CKD patients. Objective The aim of this study was to determine the effects of a low-protein diet supplemented with ketoacids compared to a conventional low protein on nutritional indices in predialysis CKD patients. Methods and materials A randomized controlled trial with a total of 60 participants was conducted at Delta State University Teaching Hospital (DELSUTH), Oghara, Nigeria. Participants were patients older than 18 years with CKD stage 3-5 who were not on dialysis. They were recruited and randomized into the intervention group (low-protein diet supplemented with ketoacids) with 30 participants and the non-intervention group (low protein with placebo) with 30 participants. The mean outcome was changed in the nutritional indices from baseline till the end of the study. Results A total of 60 patients were randomly allocated to receive a low-protein diet supplemented with ketoacids (n=30) or control (n=30). All participants were included in the analysis of all outcomes. The mean change score in serum total protein, albumin, and triglycerides between the intervention and non-intervention groups were 1.1±1.1 g/dL vs 0.1±1.1 g/dL (p<0.001), 0.2±0.9 g/dL vs -0.3±0.8 g/dL (p<0.001), and 3.0±3.5 g/dL vs 1.8±3.7 g/dL, respectively. Conclusion and recommendation The use of low-protein diet supplemented with ketoacids improved the anthropometric and nutritional indices in patients with stage 3-5 CKD.

Epidemiology Trend of Chronic Kidney Disease in a Semi-Urban Tertiary Hospital in Sub-Saharan Africa.

Background The global burden of chronic kidney disease (CKD) has been on an alarming increase in the last two decades. The morbidity and mortality associated with CKD are even worse in Nigeria, like other developing countries, due to multiple socioeconomic and demographic factors in the country. CKD contributes to the increasing need for hospital admission. Hypertension and chronic glomerulonephritis have been the leading causes of CKD in Nigeria. However, diabetic nephropathy has recently gained more significance as a cause of CKD in developing countries. Aim and methods This study aimed to describe the current trend in the burden and population characteristics of CKD in Southern Nigeria. This is a cross-sectional, hospital-based study. The study recruited adult patients with prehemodialysis CKD seen in renal clinics over a two-year period (November 2014 to October 2016). Data were obtained using a questionnaire and from the clinic register. All participants were clinically assessed, including history, anthropometric measurements, and urinary albumin-creatinine ratio. Results A total of 1,549 patients were seen at the Medical Outpatient Clinic over the study period. CKD accounted for 9.7% of medical outpatient clinic attendance. The mean age of participants was 49±13 years. The leading causes of CKD were diabetes mellitus (32%), chronic glomerulonephritis (30%), and hypertension (22%). Among the participants, CKD stages 3, 4, and 5 were prevalent in 26.7%, 43.3%, and 14.7%, respectively. Conclusion and recommendation CKD is very prevalent among medical clinic patients. Diabetic nephropathy seems to be a more significant cause of CKD than was previously reported. Late presentation of patients to nephrologists remains an obstacle to improving CKD outcome in Nigeria. There is need for more intensive preventive measures and early intervention.

Prevalence and Predictors of Peripheral Vascular Disease Amongst Predialysis Hypertensive Chronic Kidney Disease Patients in Southern Nigeria.

BACKGROUND: Peripheral vascular disease (PVD) is an atherosclerotic disease associated with increased morbidity and mortality among chronic kidney disease (CKD) patients. However, despite the substantial burden of PVD in CKD, local data are lacking. OBJECTIVE: To determine the prevalence and predictors of PVD in predialysis CKD patients. METHOD AND MATERIALS: The study was cross-sectional. One hundred fifty hypertensive CKD patients and age- and sex-matched hypertensive non-CKD subjects were consecutively enrolled at the renal unit of Delta State University Teaching Hospital (DELSUTH), Oghara. Structured questionnaires were used to obtain information on participants' demographic data and health status. PVD was defined by an ankle-brachial index of < 0.9 or > 1.4 in either lower extremity. eGFR was calculated from serum creatinine using the MDRD equation. RESULTS: The mean ages of the study and control groups were 48±14 and 51±15years, respectively. The sex ratio was 3:2 in favour of males for both the study and control groups. The majority of the study group was in CKD stage 4 (44%). The prevalence of PVD was higher among the CKD group compared with controls (24.0% vs. 14.7%). Of the CKD patients with PVD, 11.1% were symptomatic. Predictors of PVD in the study group were eGFR (B=0.010, 95%CI: 0.007-0.013), diastolic BP (B=-0.005, 95%CI: -0.007- -0.002), MAP (B=-0.018, 95%CI: -0.027- -0.008), urinary ACR (B=-0.0036, 95%CI: -0.040- -0.024) and smoking history (p<0.001, OR=14.71). CONCLUSION AND RECOMMENDATION: PVD is common and largely asymptomatic in CKD patients. The predictors of PVD in this study were eGFR, diastolic BP, mean arterial pressure (MAP), urinary albumin to creatinine ratio (ACR), and smoking. A proactive assessment of PVD and early intervention in CKD patients is needed.

Risk Assessment of Pre-dialysis Chronic Kidney Disease (CKD) Patients for Cardiovascular Disease (CVD) in a Tertiary Hospital in Nigeria: A Case-Controlled Cross-Sectional Study.

INTRODUCTION: Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in the chronic kidney disease (CKD) population. CKD patients are more likely to die from CVD before ever reaching end-stage renal disease (ESRD). The study, therefore, seeks to identify the prevalence of risk factors of CVD in CKD patients such as systemic hypertension, anemia, dyslipidemia, hypoalbuminemia, albuminuria, and abnormal calcium/phosphate products. METHODS: The study was a case-control cross-sectional study where one hundred fifty hypertensive CKD patients and age- and sex-matched hypertensive non-CKD subjects were consecutively enrolled at the renal unit of Delta State University Teaching Hospital (DELSUTH), Oghara. RESULTS: The findings of the study revealed the mean ages of cases and controls to be 48.91±11.93 years and 51.0±15.45 years respectively (p-value 0.182). There was an equal number of males and females among the study group and controls (92 males and 58 females) making a male-to-female ratio of 3:2. The prevalence of CVD risk factors such as diabetes mellitus, hypercholesterolemia, hypertriglyceridemia, elevated low-density lipoprotein, anemia, hypocalcemia, hyperphosphatemia, albuminuria, and hypoalbuminemia was significantly higher among the CKD group compared to controls. Similarly, the prevalence of reduced high-density lipoprotein (HDL) was higher among cases than controls, the difference was however not statistically significant. CONCLUSION: The study has shown that systemic hypertension, diabetes, anemia, dyslipidemia, hypoalbuminemia, albuminuria, and abnormal calcium/phosphate products increases the risk for CVD in the general population but is more expressed and significant in CKD patients.
