Summary
Leptospirosis in elderly patients often presents severely, with high rates of co-morbidity and significant risks of death. Prompt intensive treatment is crucial for managing this re-emerging zoonotic disease in older adults.
Area of Science:
- Infectious Diseases
- Geriatrics
- Zoonotic Diseases
Background:
- Leptospirosis is a zoonotic disease with a wide range of clinical presentations and high mortality in severe cases.
- Elderly individuals may experience unique challenges and increased risks when contracting leptospirosis.
Purpose of the Study:
- To analyze the clinical manifestations, laboratory findings, epidemiological data, and management of leptospirosis in elderly patients.
- To identify risk factors and outcomes associated with leptospirosis in this demographic.
Main Methods:
- A descriptive analysis of 15 elderly patients (age 60-78) diagnosed with leptospirosis between 1976 and 2012.
- Serological confirmation using the microscopic agglutination test.
- Review of clinical data, laboratory results, and patient outcomes.
Main Results:
- 80% of cases presented with severe leptospirosis.
- 13 out of 15 patients had co-morbidities, including hypertension, chronic pulmonary disease, alcohol abuse, and diabetes.
- Common symptoms included fever, oliguria, conjunctival suffusions, hepatosplenomegaly, jaundice, and hemorrhagic diathesis.
- Significant renal and hepatic dysfunction were observed.
- A 33% mortality rate was recorded in this elderly cohort.
Conclusions:
- Leptospirosis in the elderly is frequently severe and carries a higher risk of mortality.
- Early and intensive treatment is essential for improving outcomes in elderly patients with leptospirosis.
- The presence of co-morbidities exacerbates the severity and prognosis of leptospirosis in older adults.

01:30Bacterial Phylum Spirochaetes
Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased by a...
01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion
In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...
01:15Drug Dosing: Geriatric Patients
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...
01:00Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution
Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are not...
01:28Acute Pyelonephritis II: Diagnostic Studies and Management
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...
01:22Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...
