L-methionine as immune supportive supplement: a clinical evaluation

Area of Science:

• Immunology
• Clinical Nutrition
• Infectious Diseases

Background:

• Human Immunodeficiency Virus (HIV) infection leads to immune deficiency.
• Nutritional support is crucial for managing HIV and its complications.
• L-methionine, an essential amino acid, plays a role in immune function.

Purpose of the Study:

• To evaluate L-methionine as an immune-supportive supplement in HIV-infected patients.
• To assess the effect of L-methionine on CD4+ T-cell counts and clinical parameters.

Main Methods:

• A double-blind, placebo-controlled clinical study involving 253 HIV patients across four centers.
• Patients were randomized into active (L-methionine) and placebo groups.
• Regular clinical and safety assessments were conducted over a 48-month follow-up period.

Main Results:

• Statistically significant differences were observed after six months.
• Females in the L-methionine group showed a decreased rate of CD4 count decline (p=0.0027).
• Patients at Centre 1 also exhibited a significant decrease in CD4 count decline (p=0.0377).
• Observed tendencies were consistent throughout the study, with no serious treatment-related side effects.

Conclusions:

• L-methionine demonstrated a supportive role in immune-compromised patients with HIV.
• The findings suggest L-methionine can help mitigate immune decline in HIV-infected individuals.
• Further research into L-methionine as an adjunct therapy for HIV is warranted.
