Abstract
The objective of this study is to clarify whether PBM for measures reduction can cause significant changes in the lipid profile. This is an integrative review and only original articles, both in vivo and clinical trials, that were published between 2010 and 2022 were selected. The article references were also analyzed to identify additional studies. A total of 15 articles were critically analyzed. The wavelength used ranged from 532 nm (green) to 956 nm (near infrared), and many authors failed to describe dosimetric parameters properly, as well as other important characteristics for the reproducibility of those found. Although it is not fully clear about the PBM interference level on the lipid profile, in general, there was no significant difference in lipid parameters when PBM was used alone, and when associated with techniques that promote beta-oxidation, there was an improvement in these biochemical variables. PBM use for localized fat reduction do not affect lipid serum levels. Clinical trials using standardized parameters are crucial to obtain more reliable results.

Evaluation of lipolysis and toxicological parameters of low-level laser therapy at different wavelengths and doses in the abdominal subcutaneous tissue. Lasers Med Sci 2021; 37:1235-1244. [PMID: 34297266 DOI: 10.1007/s10103-021-03378-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2021] [Accepted: 07/13/2021] [Indexed: 11/25/2022]
Abstract
Investigate the effects of low-level lasers therapy (LLLT) aiming abdominal lipolysis. Female Wistar rats received applications of LLLT directly in the abdominal skin twice a week (5 weeks). Except the control group (n = 5), animals received treatments with red wavelength 660 nm being (I) R3.3 group (n = 5): 3.3 J/cm2, and (II) R5 group (n = 5): 5 J/cm2, or infrared wavelength 808 nm being (III) IR3.3 group (n = 5): 3.3 J/cm2, and (IV) IR5 group (n = 5): 5 J/cm2. Abdominal subcutaneous and liver tissues were evaluated histologically. Levels of thiobarbituric acid reactive substances (TBARS) and catalase (CAT) activity were analyzed in liver tissue. In the peripheral blood aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglycerides, and total cholesterol were investigated. Micronucleus assay was performed in the bone marrow. Except for the IR3.3 group, all treated groups reduced the body weight (p < 0.001). The R5 group reduced the abdominal subcutaneous tissue weight and thickness (p < 0.05), even though all treated groups reduced the number of adipocytes and its size (p < 0.001). No histological changes in the liver. There were no alterations in the triglycerides and LDL levels. The IR5 group increased the total cholesterol levels and decreased the HDL, ALT (both p < 0.05), and AST levels (p < 0.001). The group IR3.3 showed higher levels of ALP (p < 0.01). The R3.3 group increased the TBARS and CAT activity (p < 0.05). No mutagenic effects were found. The red laser treatment at 5 J/cm2 led to lipolysis and did not alter the liver's parameters.
