Summary
This case report highlights drug-induced interstitial pneumonitis caused by thalidomide, a rare complication in multiple myeloma patients. Early withdrawal of thalidomide treatment led to symptom and HRCT improvement.
Area of Science:
- Pulmonology
- Oncology
- Pharmacology
Background:
- Multiple myeloma is a hematologic malignancy.
- Thalidomide is a common treatment for multiple myeloma.
- Interstitial pneumonitis is a potential adverse effect of medications.
Observation:
- A 68-year-old man with multiple myeloma presented with fever and dyspnea after thalidomide treatment.
- Chest HRCT revealed diffuse ground-glass attenuation and interlobular septal thickening.
- Bronchoalveolar lavage (BAL) showed lymphocytosis, and transbronchial lung biopsy (TBLB) indicated alveolitis.
Findings:
- The patient was diagnosed with thalidomide-induced interstitial pneumonitis.
- This condition is rare, with only four previous cases reported.
- Discontinuation of thalidomide resulted in clinical and radiological improvement.
Implications:
- Clinicians should consider thalidomide-induced interstitial pneumonitis in multiple myeloma patients presenting with respiratory symptoms.
- Early diagnosis and drug withdrawal are crucial for managing this rare adverse event.
- Further research is needed to understand the mechanisms and incidence of thalidomide-induced lung injury.

Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
Pulmonary Tuberculosis I
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Immunodeficiency Diseases
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.

Hypersensitivity Reactions: Delayed Hypersensitivity Reactions
Delayed-Type Hypersensitivity (DTH), or Type IV hypersensitivity, is a cell-mediated immune response. It occurs when T cells, rather than antibodies, mediate a reaction to specific antigens. It is characterized by a delayed onset (1-2 days) and involves the recruitment of macrophages to the inflammation site.The initiation of a DTH response begins with the sensitization of T cells. During this phase, which lasts at least 1-2 weeks, antigen-specific T cells are activated, clonally expanded, and...
Pulmonary Tuberculosis IV
Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
