Comparative Assessment of Echocardiographic Patterns Among Chronic Myeloid Leukemia Patients on Tyrosine Kinase Inhibitor and Healthy Controls.

PURPOSE: Chronic myeloid leukemia (CML) is one of the common hematological malignancies in Nigeria. Cardiac abnormalities are associated with CML irrespective of treatment with tyrosine kinase inhibitors such as imatinib, which is available gratis in Nigeria. OBJECTIVE: To assess the prevalence and patterns of cardiac dysfunction among patients with CML irrespective of treatment with imatinib using transthoracic echocardiography, and 12-lead surface electrocardiography. PATIENTS AND METHODS: CML patients without Imatinib, CML patients with imatinib, and apparently healthy (age- and sex-matched) controls were 70 each in the study. Various echocardiographic parameters were measured and data obtained were analyzed, and the level of significance was taken as p < 0.05. RESULTS: Of 70 CML patients with imatinib, 54.3% were men and 45.7% were women, while the CML group without imatinib had 62.9% men and 37.1% women, non-CML control had 54.3% men and 45.7% women. The average hematocrit was significantly lower in the CML group without Imatinib compared with the other groups (p<0.001). And, 12.9% and 17.1% of CML groups with and without imatinib had LVH, respectively, and none of the non-CML controls had LVH (P<0.041). Impaired left ventricular relaxation in 25.71% and 28.57% of CML patients with and without imatinib respectively but only 8.57% of the non-CML control had impaired left ventricular relaxation (p=0.236). Mitral valve regurgitation was the most frequent valvular abnormality across the groups. Pulmonary hypertension in 17.4% and 20% of CML patients with and without imatinib, respectively, but none of the non-CML controls had pulmonary hypertension (p<0.001). Pericardial effusion in 32.86% and 45.71% of CML patients with and without imatinib, respectively, but none of the non-CML controls had pericardial effusion (p<0.001). There was no significant difference in the QTC interval across the three groups. CONCLUSION: Cardiac abnormalities are present in CML patients with or without Imatinib treatment, with significant prevalence than what is seen in the non-CML control group.

Black Pleural Effusion as a Complication of Acute Pancreatitis.

Transient and reactive pleural effusion is a known consequence of acute pancreatitis. Usually, the pleural effusion is unilateral, transudate, straw-colored, and self-resolving. We report a rare case of massive left-sided black pleural effusion as a complication of acute pancreatitis with the background of chronic pancreatitis being secondary to alcohol abuse. The pleural effusion resulted in hypoxic respiratory failure. However, the patient had significant improvement after drainage of the pleural effusion and the appropriate management of sepsis with broad-spectrum antibiotics. The patient had a significant improvement and recovery with conservative management without the need for endoscopic therapy or surgical intervention.

Ventricular Arrhythmias in Seniors with Heart Failure: Present Dilemmas and Therapeutic Considerations: A Systematic Review.

BACKGROUND: Heart Failure (HF) is a global public health problem, which affects over 23 million people worldwide. The prevalence of HF is higher among seniors in the USA and other developed countries. Ventricular Arrhythmias (VAs) account for 50% of deaths among patients with HF. We aim to elucidate the factors associated with VAs among seniors with HF, as well as therapies that may improve the outcomes. METHODS: PubMed, Web of Science, Scopus, Cochrane Library databases, Science Direct, and Google Scholar were searched using specific keywords. The reference lists of relevant articles were searched for additional studies related to HF and VAs among seniors as well as associated outcomes. RESULTS: The prevalence of VAs increases with worsening HF. A 24-hour Holter electrocardiogram may be useful in risk stratifying patients for device therapy if they do not meet the criterion of low ventricular ejection fraction. Implantable Cardiac Defibrillators (ICDs) are superior to anti-arrhythmic drugs in reducing mortality in patients with HF. Guideline-Directed Medical Therapy (GDMT) together with device therapy may be required to reduce symptoms. In general, the proportion of seniors on GDMT is low. A combination of ICDs and cardiac resynchronization therapy may improve outcomes in selected patients. CONCLUSION: Seniors with HF and VAs have high mortality even with the use of device therapy and GDMT. The holistic effect of device therapy on outcomes among seniors with HF is equivocal. More studies focused on seniors with advanced HF as well as therapeutic options are, therefore, required.

Crowned Dens Syndrome Masquerading as Meningitis.

The classic symptoms of meningismus, including fever, neck stiffness, and headache, should automatically trigger a prime differential of meningitis, but a close masquerader, albeit rare, is crowned dens syndrome. Herein, we report the case of a 71-year-old woman with clinical features of meningismus with elevated inflammatory biomarkers. However, computed tomography of the cervical spine revealed the presence of calcium deposits encircling the dens. Hence, an alternate diagnosis of crowned dens syndrome was considered. This was confirmed by the presence of similar pathology in other joints and the dramatic resolution of symptoms and inflammatory markers with the administration of nonsteroidal anti-inflammatory drugs.

Mixed connective tissue disease complicated by heart failure in Ile-Ife, Nigeria: management challenges in a resource-limited economy.

BACKGROUND: Mixed connective tissue disease (MCTD; also known as Sharp's syndrome) is a rare autoimmune inflammatory disorder characterized by high titer of U1 ribonucleoprotein (U1RNP) antibody and clinical and serological overlap of systemic lupus erythematosus, systemic sclerosis, and polymyositis. The diagnosis is based on clinical and serological factors in criteria such as Alarcon-Segovia, Khan, Kusakawa, and Sharps. Cardiac disease can be a complication of connective tissue disease (CTD). There are few reports in Africa. AIMS: To present MCTD as underlying cause of heart failure with reduced ejection fraction and highlight challenges of investigations and treatment. OBJECTIVES: To highlight the first case in our center and discuss the cardiac, respiratory, and rheumatologic management. PATIENT AND METHODS: We present a 52-year-old woman with 3 weeks history of productive cough with whitish sputum, severe dyspnea, orthopnea, paroxysmal nocturnal dyspnea, right sided abdominal pain, leg swellings, a one year history of recurrent fever, Raynaud's phenomenon, small joint swellings and deformities with pain in both hands. RESULTS: On examination there was microstomia, tethered forehead and lower eyelid skin, tender swelling of the interphalangeal joints and arthritis mutilans. Laboratory findings showed estimated glomerular filtration rate <60 mL/kg/min/1.73 m2, U1RNP antibody levels were eight times upper limit of normal, elevated rheumatoid factor, speckled antinuclear antibody pattern, negative anticentromere antibody, anti Scl-70 and anticyclic citrullinated peptide. Chest X-ray/CT revealed pulmonary fibrosis. Echocardiography findings showed reduced ejection fraction of 40%, elevated pulmonary arterial pressure at rest of 60.16 mmHg. The patient showed improvement on antifailure drugs, but prednisolone was stopped for sudden reversal of previously controlled stage 2 hypertension (HTN), and the patient was discharged in a stable condition. Difficulties ensued in obtaining prompt definite results due to the unavailability of serologic tests in the hospital, and the tests were done outside the state and country. CONCLUSION: Identifying MCTD is critical, especially in patients requiring steroids that may worsen systemic HTN and heart failure. There is a need to have definitive investigative facilities for such patients in hospitals.
