Summary
A 16-day desensitization protocol effectively managed non-immediate hypersensitivity reactions to lenalidomide. This approach offers a safe treatment option for patients experiencing these delayed drug reactions.
Area of Science:
- Immunology
- Pharmacology
- Clinical Medicine
Background:
- Standardized desensitization protocols exist for immediate hypersensitivity reactions (HRs) to chemotherapeutics.
- However, standardized protocols for non-immediate HRs are lacking.
- Lenalidomide can induce non-immediate hypersensitivity reactions.
Purpose of the Study:
- To evaluate the efficacy and safety of a 16-day desensitization protocol for lenalidomide-induced non-immediate hypersensitivity reactions.
Main Methods:
- A previously published slow desensitization protocol was adapted.
- Patients received 1/100 of the daily dose, with gradual increases over 16 days.
- Demographic and clinical data were collected.
Main Results:
- Ten patients with non-immediate hypersensitivity reactions to lenalidomide were included.
- Successful desensitization was achieved in 9 out of 10 patients within 16 days.
- One patient required a modified, slower protocol over 35 days due to maculopapular eruptions.
Conclusions:
- The 16-day desensitization protocol appears safe and effective for managing non-immediate hypersensitivity reactions to lenalidomide.
- This protocol provides a viable treatment option for patients with delayed hypersensitivity to lenalidomide.

8.0K
G protein-coupled receptor (GPCR) signaling plays a crucial role in cell functioning. GPCR desensitization is an equally essential process. It allows cells to respond to changing environments and regain sensitivity to new stimuli while preventing unnecessary stimulation when no longer needed. Prolonged exposure to stimuli leads to GPCR desensitization. It involves blocking the receptors from binding and activating additional G proteins. This inhibits activation of downstream effectors, thereby...

01:20Desensitization and Tachyphylaxis
3.0K
Tachyphylaxis is described as a rapid decrease in response to a drug after repeated or continuous administration of the same drug dose. It is a phenomenon where the body becomes less responsive to a particular substance or intervention over time, requiring higher doses or stronger interventions to achieve the same effect. It results from adaptive changes in the body's receptors, signaling pathways, or physiological processes that occur in response to prolonged exposure to a stimulus.

7.3K
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

2.4K
Raymond Cattell's trait theory offers a structured framework for understanding personality by distinguishing between two critical traits: surface and source traits. Surface traits are observable patterns of behavior, such as indecisiveness, anxiety, and irrational fears. These traits are less stable, varying across situations and over time. This means that they are less helpful in understanding the deeper aspects of an individual's personality.
In contrast, source traits are the...

01:16Characteristics of Practical Op Amps
835
A difference amplifier, a crucial component in numerous electronic devices, ideally amplifies only the difference-mode signal, which is the difference between two input signals. However, in practical circuits, the output voltage depends on both the differential gain and the common-mode gain.
The ratio of differential gain to the common-mode gain is defined as the common-mode rejection ratio (CMRR). This ratio quantifies the ability of operational amplifiers (op-amps) to reject common-mode...
