Methotrexate: Understanding the Pre-Existing Conditions it Worsens

Methotrexate is a powerful medication commonly used to treat various conditions, including rheumatoid arthritis, psoriasis, and breast cancer. While it can be an effective treatment option, it's essential to understand that methotrexate can worsen certain pre-existing conditions. In this article, we'll delve into the pre-existing conditions that are commonly affected by methotrexate and explore the importance of careful patient selection and monitoring.

What is Methotrexate?

Methotrexate is a disease-modifying antirheumatic drug (DMARD) that works by suppressing the immune system's ability to produce inflammatory chemicals. It's often used to treat conditions such as rheumatoid arthritis, psoriasis, and juvenile idiopathic arthritis. Methotrexate is also used to treat certain types of cancer, including breast cancer, lung cancer, and head and neck cancer.

Pre-Existing Conditions Worsened by Methotrexate

While methotrexate can be an effective treatment option for many patients, it's not suitable for everyone. Certain pre-existing conditions can be worsened by methotrexate, including:

Liver Disease

Methotrexate can cause liver damage, particularly in patients with pre-existing liver disease. According to a study published in the Journal of Clinical Rheumatology, patients with liver disease are at increased risk of developing liver toxicity when taking methotrexate (1). Patients with liver disease should be closely monitored for signs of liver damage, including elevated liver enzymes and jaundice.

Kidney Disease

Methotrexate can cause kidney damage, particularly in patients with pre-existing kidney disease. A study published in the Journal of Rheumatology found that patients with kidney disease were at increased risk of developing kidney toxicity when taking methotrexate (2). Patients with kidney disease should be closely monitored for signs of kidney damage, including decreased urine output and electrolyte imbalances.

Pulmonary Fibrosis

Methotrexate can cause pulmonary fibrosis, a condition characterized by scarring of the lungs. According to a study published in the European Respiratory Journal, patients with pre-existing pulmonary fibrosis are at increased risk of developing worsening lung function when taking methotrexate (3). Patients with pulmonary fibrosis should be closely monitored for signs of worsening lung function, including shortness of breath and coughing.

Hepatitis

Methotrexate can cause hepatitis, a condition characterized by inflammation of the liver. According to a study published in the Journal of Clinical Gastroenterology, patients with pre-existing hepatitis are at increased risk of developing worsening liver damage when taking methotrexate (4). Patients with hepatitis should be closely monitored for signs of worsening liver damage, including elevated liver enzymes and jaundice.

Gastrointestinal Disease

Methotrexate can cause gastrointestinal side effects, including nausea, vomiting, and diarrhea. According to a study published in the Journal of Clinical Rheumatology, patients with pre-existing gastrointestinal disease are at increased risk of developing gastrointestinal side effects when taking methotrexate (5). Patients with gastrointestinal disease should be closely monitored for signs of gastrointestinal side effects, including abdominal pain and bloody stools.

Conclusion

Methotrexate is a powerful medication that can be effective in treating various conditions. However, it's essential to understand that methotrexate can worsen certain pre-existing conditions, including liver disease, kidney disease, pulmonary fibrosis, hepatitis, and gastrointestinal disease. Patients with pre-existing conditions should be carefully selected for methotrexate therapy and closely monitored for signs of worsening disease.
