The Evaluation of Lymphadenopathy in a Resource-Limited Setting

Lymphadenopathies: A Retrospective Study of Epidemiology, Characteristics, Diagnosis and Treatment Outcomes of Patients in a Tertiary Hospital in Mogadishu-Somalia

Introduction

Lymphadenopathies, which can be caused by infections, malignant diseases, autoimmune disorders, and many other diseases, pose a challenge to clinicians in sub-Saharan Africa, as well as all over the world. The purpose of this research was to identify the clinical and diagnostic characteristics of Somalian patients suffering from swollen lymph nodes.

Methods

Under the purview of this study, the diagnoses, patient clinical courses, and treatment outcomes were ascertained retrospectively by analyzing the biochemical, microbiological, radiological, and pathological data of the cases in all age groups who underwent therapy for lymphadenitis at Mogadishu Somali Turkey Recep Tayyip Erdoğan Training and Research Hospital between January 2016 and September 2023.

Results

During the study period, 317 patients were followed up, with 53.3% of the patients as female, 46.7% as male, 28.1% as pediatric, 63.1% as adult, and 8.8% were elderly patients. With 58.7% of diagnoses, tuberculous lymphadenitis was the most common, pursued by malignant causes (21.8%). The most commonly affected lymph node was the cervical region, the symptom detected was lymph node swelling, the radiological method used was ultrasonography, and the biopsy method was fine needle aspiration biopsy. It was determined that benign conditions, including tuberculosis were more common in pediatric group and younger adults (p<0.001), and weight loss was a significant in terms of malignancy and tuberculosis (p<0.001). White blood cell value (p<0.001), erythrocyte sedimentation rate (p<0.001), and C-reactive protein (p:0.001) revealed differences across the diagnostic groups.

Conclusion

Almost two-thirds of patients were diagnosed with tuberculosis lymphadenitis. Our finding revealed tuberculosis as the commonest cause of lymphadenopathy followed by malignant causes. Therefore, before screening for malignant causes, tuberculosis should be the first diagnosis considered in Somalia, particularly in a patient presenting with weight loss and swelling of the lymph nodes.

Lymphoma and Other Lymph Node Pathologies Among Adult Patients with Lymphadenopathy in Abakaliki, Nigeria

INTRODUCTION

Lymphadenopathy is usually due to benign or malignant conditions. It can also be local or systemic in distribution and can involve peripheral or deep-seated lymph nodes. This study aimed to determine the prevalence of lymphoma and the distribution pattern of lymph node pathologies among adult patients who presented with lymphadenopathy and its relationship with age and sex.

METHODS

A retrospective study was conducted, and a record of all cases of lymphadenopathy with histological diagnosis over 5-year period (January 2017 to December 2021) was extracted from Departments of Anatomical Pathology of Alex Ekwueme Federal University Teaching Hospital, Abakaliki. The data generated were analyzed using Statistical Package for Social Sciences (SPSS) software, version 26.

RESULTS

One hundred and ninety results were extracted with an age range of 18 to 94 years and a mean age of 41 ± 16 years. They were made up of 75 (39.5%) males and 115 (60.5%) females, with a male-to-female ratio of 1:1.5. The prevalence of lymphoma was 50.0% (95/190). Thirty-five (18.4%) were Hodgkin's lymphoma (HL), while 60 (31.6%) were non-Hodgkin's lymphoma (NHL). Other pathologies manifested by cases of lymphadenopathy include metastatic tumor deposits (38 (20%)), reactive lymphoid hyperplasia (29 (15.3%)), and tuberculous lymphadenitis (18 (9.5%)). Others include sinus histiocytosis (4 (2.1%)), dermatopathic lymphadenitis (5 (2.6%)), and Castleman's disease (1 (0.5%)).

CONCLUSION

About half of all patients who presented with lymphadenopathy were lymphoma with a high prevalence of 50%, and the majority were NHL. Other major causes of lymphadenopathy were metastatic tumor deposits, reactive lymphoid hyperplasia, and tuberculous lymphadenitis. Any case of lymphadenopathy should be properly investigated early for effective management.

Distal Gastrectomy With Roux-en-Y Reconstruction for a Seriously Dilated Stomach With Gastric Outlet Obstruction Secondary to Sarcina ventriculi: A Case Report

Sarcina ventriculi is an anaerobic gram-positive coccus that can resist the acidic media of the stomach and cause gastrointestinal symptoms. Here, we report the case of a 43-year-old male patient with a history of schizophrenia presenting with abdominal distention, nausea, vomiting, early satiety, and weight loss. Computed tomography of the abdomen and pelvis with contrast revealed a severely dilated stomach and signs of gastric outlet obstruction on multiple occasions. The endoscopic evaluation showed a dilated stomach, and biopsies revealed non-specific gastritis, negative Helicobacter pylori, and positive S. ventriculi with metaplasia. Medical treatment with proton pump inhibitors, pro-kinetics, ciprofloxacin, and metronidazole failed to improve his symptoms. Finally, the patient was managed surgically with distal gastrectomy with Roux en Y reconstruction, and gastrostomy tube placement was done with satisfactory improvement in his symptoms.
