Hepatocellular Liver Function of Immunosuppressed Rats with Oral Candidiasis
after Hyperbaric Oxygen Treatment: Alanine Transaminase and Aspartate Transaminase Levels

Hepatocellular utility is observed by measuring the hepatocellular enzymes. Changes in its serum levels are related to liver dysfunction. Liver is one of the immunoprotective organs. Continuous use of immunosuppressive drugs can cause oral candidiasis and give effects to liver function. Hyperbaric oxygen treatment (HBOT), while reducing fungal infections, can also repair the liver function. The aim of this study was to investigate the alanine transaminase (ALT) and aspartate transaminase (AST) levels of immunosuppressed rats with oral candidiasis treated with hyperbaric oxygen. Twelve Wistar rats were divided into three groups: K− (normal/ healthy), K+ (oral candidiasis immunosuppressed rats), and P (oral candidiasis immunosuppressed rats treated hyperbaric oxygen). K+ and P groups were immunosuppressed by giving dexamethasone 0.5 mg/day/rat orally for 14 days, added with tetracycline 1 mg/day/rat. HBOT was given in five days successively. Blood serum of rats in all groups were taken to calculate the ALT and AST levels. ALT and AST levels in K+ showed higher value than K− and P groups. The data were analysed with one-way ANOVA test and showed significant difference in ALT levels (p < 0.05), while in AST levels there was no significant difference among the groups (p > 0.05). This study showed that HBOT affected the ALT and AST levels of immunosuppressed rats with oral candidiasis.

Objective: To investigate serum albumin levels in oral candidiasis immunosuppressed rats treated with hyperbaric oxygen. One of the predisposing factors for oral candidiasis was the use of immunosuppressive drugs continuously. It can also affect the work of the liver because it’s one of the organs responsible for drug metabolism. Hyperbaric oxygen therapy was used not only to suppressing fungal infections, but also to improve liver function by evaluating the serum albumin levels. Methods: This study used a post-test only control group design. Fifteen Wistar rats were divided into 3 groups(n=5/3): G1 (healthy group), G2 (oral candidiasis immunosuppressed rats group without hyperbaric oxygen therapy), and G3 (oral candidiasis immunosuppressed rats group with hyperbaric oxygen therapy). G2 and G3 groups were immunosuppressed by giving dexamethasone 0,5mg/day/rat orally for 14 days, added with tetracycline 1 mg/day/rat. Hyperbaric oxygen therapy was given to the G3 group in 5 days. Blood serum of rats in all groups was taken to calculate albumin levels. Results: The average value of albumin levels in G2 group showed a decrease compared to the G1 group, while G3 showed the highest level. One way Anova test showed a significant difference among groups (p<0,05). To compare the difference between each group we used LSD test and showed a significant difference (p<0,05) between G1 compared to G2, G1 compared to G3, and G2 compared to G3. Conclusion: Liver albumin levels of oral candidiasis immunosuppressed rats treated with hyperbaric oxygen therapy showed higher levels than those without therapy.

Record Review

Hyperoxic myopia is a phenomenon reported in individuals who have prolonged exposure to an increased partial pressure of oxygen (PO2) and subsequently have a myopic (nearsighted) change in their vision. To date, there are numerous accounts of hyperoxic myopia in dry hyperbaric oxygen treatment patients; however, there have been only three confirmed cases reported in wet divers. This case series adds four confirmed cases of hyperoxic myopia in wet divers using 1.35 atmospheres (ATM) PO2 at the Navy Experimental Diving Unit (NEDU). The four divers involved were the first author’s patients at NEDU. Conditions for two divers were confirmed via record review, whereas the other two divers were diagnosed by the first author. All subjects were interviewed to correlate subjective data with objective findings. Each subject completed five consecutive six-hour hyperoxic (PO2 of 1.35 ATM) dives with 18-hour surface intervals. Each individual was within the U. S. Navy Dive Manual’s standards for general health. Visual acuity was measured prior to diving. Within three to four days after diving, the individuals reported blurry vision with an associated myopic refraction shift. Each diver had spontaneous resolution of his myopia over the next two to three weeks, with no significant residual symptoms. The divers in this case series were exposed to an increased PO2 (1.35 ATM for 30 hours over five days), a lesser exposure than that in other reports of hyperoxic myopia in wet divers diagnosed with hyperoxic myopia (1.3-1.6 ATM for 45-85 hours in 12-18 days). Furthermore, this pulse of exposure was more concentrated than typically seen with traditional hyperbaric oxygen therapy. Hyperoxic myopia continues to be a risk for those conducting intensive diving with a PO2 between 1.3-1.6 ATM. Additional investigation is warranted to better define risk factors and PO2 limits regarding ocular oxygen toxicity.
