Abstract

Background:

Diabetes mellitus is a chronic metabolic disorder that is well known for its long term serious complications. Proteinuria whether micro or macroproteinuria is one of these complications. Many studies has related proteinuria to other complications of diabetes as retinopathy and cardiovascular disease of diabetes, while the lungs of diabetic patients which is the largest organ in the body with a large macro and microvascular bed, has not been related to this complication.

Aim:

The aim of the study was to find out whether proteinuria in diabetic patients can predict lung involvement.

Patients And Methods:

A comparative cross sectional study in which we compared the lung function of 100 type 2 diabetic patients with proteinuria with that of 100 type 2 diabetic patients without proteinuria. Proteinuria is measured in a random sample by "urine protein/urine creatinine ratio". FEV1 and FVC were measured by spirometer.

Results:

The results showed that patients with proteinuria had a high frequency of abnormal PFT (86%), while patients without proteinuria had a low frequency of abnormal PFT (11%).Also diabetic patients with proteinuria had lower FVC (72.9 ± 6.5 vs. 88.2 ± 8.2), than diabetic patients without proteinuria.

Conclusions:

We concluded that diabetes mellitus causes a significant impairment in pulmonary function test. This impairment is significantly related with proteinuria.

Diabetes Mellitus: Type 2 and Gestational

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Predicting Products: SN1 vs. SN2

Predicting Products: S_N1 vs. S_N2

Nucleophilic substitution reactions of alkyl halides can proceed via an SN1 or an SN2 mechanism. While in SN2 reactions, the nucleophile attacks the substrate simultaneously as the leaving group departs, in SN1 reactions, the substrate first dissociates to give the carbocation intermediate. Various factors such as the structure of the substrate, the strength of the nucleophile, and the nature of the solvent promote one mechanism over the other.
With increased substitution on the alkyl halide,...

Diabetes Mellitus: Overview and Type I Subtype

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Range

Range

The range is one of the measures of variation. It can be defined as the difference between a dataset's highest and lowest values. For example, in the study of seven 16-ounce soda cans, the filled volume of soda was measured, thus producing the following amount (in ounces) of soda:
15.9; 16.1; 15.2; 14.8; 15.8; 15.9; 16.0; 15.5
Measurements of the amount of soda in a 16-ounce can vary since different subjects record these measurements or since the exact amount - 16 ounces of liquid, was not...

Nephrotic Syndrome I : Introduction

Nephrotic Syndrome I : Introduction

Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...
