An Unusual Case of an Immunocompetent Adult Diagnosed With Cytomegalovirus Colitis

Cytomegalovirus (CMV) infections are typically considered opportunistic in individuals with immunosuppressive conditions such as human immunodeficiency virus/acquired immunodeficiency syndrome, underlying malignancies, organ or bone marrow transplantation, and those receiving chemotherapeutics or steroids. Nevertheless, there is a significant increase in reported instances of CMV infections globally, suggesting that even individuals with a healthy immune system might experience these infections. In such cases, the primary symptoms are typically related to the gastrointestinal system, such as ulcerative colitis, pseudopolyps, tumors, and ischemic and hemorrhagic enterocolitis. We present a unique instance of severe CMV colitis in a patient with a fully functioning immune system. The diagnosis of CMV colitis was determined through the histological analysis of biopsy tissues acquired during colonoscopy.

Atypical Presentation of a Patient With Progressive Multifocal Leukoencephalopathy

Progressive multifocal leukoencephalopathy (PML) is a rare, demyelinating infectious disease of the central nervous system, primarily affecting immunosuppressed individuals, such as those with acquired immunodeficiency syndrome (AIDS) or undergoing immunosuppressive therapy. The causative agent is the dormant John Cunningham (JC) polyomavirus, which reactivates in immunocompromised patients. PML is diagnosed through clinical observations, imaging, and polymerase chain reaction (PCR) analysis, detecting JC virus deoxyribonucleic acid (DNA) in the cerebrospinal fluid (CSF). Here, we report a case of a 42-year-old male, recently diagnosed with human immunodeficiency virus (HIV), who presented with slurred speech, difficulty articulating, tingling in both feet, difficulty walking, and significant weight loss. Examination revealed absent reflexes, coordination impairment, and diminished vibration sense. Blood tests showed anemia, elevated D-dimer, and HIV-1 positivity with a low CD4 count. CSF analysis indicated a lymphocytic profile with elevated protein and marginally increased adenosine deaminase (ADA). Autoantibody testing was positive for antinuclear antibodies (ANA), but CSF culture and India ink staining were negative. Magnetic resonance imaging (MRI) of the brain revealed hyperintense lesions on T2-weighted and fluid-attenuated inversion recovery (FLAIR) images in the left peritrigonal and parietal white matter, suggesting demyelination. The diagnosis of PML was confirmed by a positive JC virus PCR result from the CSF. The patient was started on combination antiretroviral therapy (cART) and supportive measures to improve immune status. This case underscores the importance of considering PML in patients with new-onset neurological symptoms and immunosuppression.

Hepatic Tuberculosis Manifested as Hepatic Abscess: A Report of a Unique Case

Millions of people around the world suffer from tuberculosis (TB), a long-term contagious illness. TB can invade almost all human body systems, with the respiratory system being the most impacted. Hepatic TB is a form of TB infection that affects the liver. It is considered an extrapulmonary manifestation of TB, which is a rare manifestation. Early identification of hepatic TB allows for prompt treatment, while leaving it untreated can result in fatality. Our patient is a 46-year-old female who presented with fever, weight loss, loss of appetite, and abdominal pain. An abdominal contrast-enhanced computed tomography (abdominal CECT) scan shows a well-defined, peripherally enhancing hypodense lesion in the liver, which helps with diagnosis. The biopsy demonstrates granulomatous inflammation accompanied by caseating necrosis. The objective of our study is to provide a detailed description of this unique condition through a case presentation.

The Role of High-Density Lipoprotein, C-reactive Protein, and Serum Ferritin in Ischemic and Hemorrhagic Stroke: An Observational Cross-Sectional Comparative Study

Background Stroke is a significant global health issue, with a high prevalence of morbidity, mortality, and disability. We can classify strokes into two types: ischemic and hemorrhagic, with ischemic strokes being more common. This study aims to investigate the role of high-density lipoprotein (HDL), C-reactive protein (CRP), and serum ferritin levels in people who have had ischemic and hemorrhagic strokes in order to identify possible biomarkers for diagnosis and treatment. Materials and methods This observational cross-sectional comparative study included 100 stroke patients (50 ischemic and 50 hemorrhagic) from Dr. D. Y. Patil Medical College, Hospital and Research Centre, Dr. D. Y. Patil Vidyapeeth (Deemed to be University), Pune. We collected data through clinical evaluations, laboratory tests, and imaging studies. We measured and analyzed HDL, CRP, and serum ferritin levels using appropriate statistical tests, such as the chi-square test and Student t-test, with a 95% confidence interval (CI) and a 5% p-value for significance. Results The mean age for ischemic stroke patients was 55.92 years, whereas for hemorrhagic stroke patients, it was 58.68 years. The study found significant differences in HDL, CRP, and ferritin levels between the two groups. The mean HDL level for ischemic stroke patients was significantly lower at 25.10 mg/dL, compared to 40.57 mg/dL in hemorrhagic stroke patients, with a p-value of <0.001. The mean CRP level was higher in ischemic stroke patients (28.90 mg/L) compared to hemorrhagic stroke patients (22.80 mg/L), with a p-value of <0.001. Ferritin levels were also higher in hemorrhagic stroke patients (587.98 ng/mL) compared to ischemic stroke patients (473.16 ng/mL), with a statistically significant p-value of <0.001. Conclusion This study highlights the significant role of HDL, CRP, and serum ferritin levels in distinguishing between ischemic and hemorrhagic stroke patients. Elevated HDL levels may protect against ischemic strokes due to their anti-inflammatory properties, while higher CRP levels in ischemic strokes indicate a strong inflammatory response. Elevated ferritin levels in hemorrhagic strokes suggest increased oxidative stress and inflammation.

Investigating Interleukin-6 Levels in Type 2 Diabetes Mellitus Patients With and Without Diabetic Nephropathy

BACKGROUND AND OBJECTIVE

Diabetic nephropathy (DN), a severe complication affecting 40% of diabetic individuals, is a leading cause of chronic kidney disease (CKD). It involves a progressive increase in urinary albumin and a decline in the glomerular filtration rate. Early detection and intervention are crucial to preventing CKD progression. The current marker, albuminuria, measured as the urine albumin-to-creatinine ratio (UACR), has limitations, highlighting the need for alternative biomarkers. Researchers have linked the proinflammatory cytokine interleukin-6 (IL-6) to the progression of DN, observing elevated levels in DN patients compared to those without DN. IL-6 also regulates glucose metabolism, promoting insulin effectiveness and secretion. Inflammation and glucose control are two things that IL-6 does. This makes it a promising biomarker and therapeutic target for DN and type 2 diabetes mellitus (T2DM). This study focuses on IL-6 levels in T2DM patients with and without DN.

METHODS AND MATERIALS

From September 2022 to June 2024, the Department of General Medicine, Dr. D. Y. Patil Medical College, Hospital and Research Centre, Dr. D. Y. Patil Vidyapeeth (Deemed to be University), Pune, conducted an observational cross-sectional comparative study on 80 T2DM patients, with 40 in group A (cases = T2DM patients with DN) and 40 in group B (controls = T2DM patients without DN). The study included patients with T2DM between the ages of 40 and 80. The study excludes conditions such as diabetic ketoacidosis, patients with end-stage renal disease, and conditions that increase IL-6, such as COVID-19. The study excluded autoimmune conditions with elevated IL-6, such as rheumatoid arthritis, systemic lupus erythematous, ankylosing spondylitis, psoriasis, and Crohn's disease. We obtained ethical approval and written consent from participants.

RESULTS

In the current study, 61 patients (76.2%) were 60 years old or younger, while 19 patients (23.8%) were older than 60 years. Among the participants, 38 were females (47.5%) and 42 were males (52.5%). The case group, which consisted of 40 T2DM patients with DN, had a mean glycated hemoglobin (HbA1c) of 7.1700 ± 0.71044. In contrast, the control group, comprising 40 T2DM patients without DN, had a mean HbA1c of 6.8650 ± 0.57179. This difference was statistically significant, with a p value of 0.038. Additionally, the mean UACR in the case group was 134.34 ± 95.56, significantly higher than the control group's mean UACR of 22.32 ± 9.90. This difference was highly significant, with a p value of 0.001. Furthermore, the case group exhibited elevated mean IL-6 levels of 15.48 ± 4.27 compared to the control group's 7.02 ± 2.46, which is also highly significant, reflected by a p value of 0.001.

CONCLUSION

As the concentration of IL-6 rises in diabetic patients with nephropathy, this study suggests that IL-6 may have an effect on the development of DN. This cytokine is necessary for both the initiation and progression of the condition. Using IL-6 as a supportive diagnostic test could help rule out other potential causes of DN in T2DM. Moreover, this marker does not require invasive procedures, and early measurement may help reduce mortality and morbidity.

Leptospirosis and Dengue Coinfection-Associated Multi-Organ Dysfunction Syndrome: A Case Report

Dengue and leptospirosis are frequently discussed separately, with dengue causing rash and leptospirosis causing jaundice. Currently, there are more and more reports of coinfections. The comparable clinical symptoms of both infections make it challenging to distinguish between leptospirosis and dengue. Differentiating between leptospirosis and dengue is crucial since leptospirosis has a more favorable prognosis with early antibiotic therapy, whereas dengue does not have a specific treatment, although early detection is essential for close monitoring and cautious fluid management. Here, we highlight a case of dengue virus and leptospirosis coinfection in a female who presented with acute febrile illness, dyspnea, and altered sensorium, which progressed to multiorgan dysfunction syndrome, involving the neurological, respiratory, hepatic, and hematological systems.

A Clinical Study of Thyroid Abnormalities and Autoantibodies in Patients Diagnosed With Anti-nuclear Antibody Positive Autoimmune Connective Tissue Disorders: An Observational Cross-Sectional Study

INTRODUCTION

Autoimmune connective tissue disorders (CTDs) are characterized by inflammation of the connective tissue structures and immune system aberrations, such as autoantibody production. This study investigates the prevalence and clinical significance of thyroid abnormalities in patients with anti-nuclear antibody (ANA)-positive autoimmune CTDs.

METHODS

This prospective cross-sectional observational study was conducted at Dr. D. Y. Patil Medical College, Hospital and Research Centre, Dr. D. Y. Patil Vidyapeeth (Deemed to be University), Pune, from September 2022 to June 2024. Eighty patients diagnosed with ANA-positive CTDs were included. Comprehensive histories were collected from them and clinical examinations and routine investigations were performed. Blood samples were collected for thyroid function tests and autoantibody tests. Thyroid ultrasound investigations were also performed. Ethical approval and informed consent were obtained.

RESULTS

The study revealed a significant prevalence of thyroid dysfunction among participants, with 39 (48.75%) exhibiting some form of thyroid abnormality. Subclinical hypothyroidism was the most common condition in 18 (22.50%) participants, predominantly affecting females. Thyroid autoantibodies were present in 32 (40%) participants, with thyroid peroxidase antibodies (anti-TPO Ab) being the most common seen in 17 (21.25%) participants. Systemic lupus erythematosus (SLE) was the most prevalent CTD among participants, seen in 44 (55%) participants, followed by Sjogren's syndrome (SS) seen in 19 (23.75%) participants.

CONCLUSION

The study underscores the necessity of routine thyroid function screening in patients with ANA-positive CTDs to facilitate early detection and management of thyroid abnormalities, thereby preventing progression to overt hypothyroidism or hyperthyroidism. The findings highlight the significant association between thyroid dysfunction and autoimmune CTDs, advocating for a holistic approach to patient care.

Acute Cerebillitis Due to Salmonella typhimurium Infection in an Adult: A Report of an Unusual Case

Acute cerebellitis is an inflammatory illness that may manifest as a primary, para-infectious, or post-infectious disease. The clinical manifestations of acute cerebellitis are traditionally characterized by fever, vomiting, headache, and altered sensorium, accompanied by impaired cerebellar function corroborated by neuroradiography alterations. Acute cerebellitis may lead to a potentially fatal increase in pressure within the skull, requiring immediate and critical neurosurgical surgery. It is important to note that cerebellar symptoms may not be evident initially. This report provides a comprehensive analysis of a case of a 57-year-old male patient who had been diagnosed with acute cerebellitis caused by an infection with Salmonella typhimurium.
