The extensive utilization of antiretroviral therapy (ART) has successfully improved human immunodeficiency virus (HIV)-associated complications. The incidence of opportunistic infections is decreased by the viral load suppression and the CD4 count promotion. However, metabolic complications, commonly bone demineralization, lipodystrophy, and lactic acidosis, are arising following the adaptation of long-term ART. The events are not drug-specific, but the severity and incidence individually vary depending upon classes of drugs. Such concerning occurrences may lead to discontinuation of current therapy or switching to another regimen with fewer adverse effects. The purpose of this review is to demonstrate the common metabolic abnormalities associated with each class of widely used ART in people living with HIV (PLHIV). Electronic databases such as PubMed, ScienceDirect, Scopus, Google Scholar, SciFinder, and Web of Science were used for the literature search. A better understanding of ART-associated metabolic adverse effects is helpful in various clinical settings so that therapists may optimize treatments in this population.

Fluoropyrimidines and irinotecan cause diarrhea, which can be particularly severe in some cases. Probiotic supplementation is a potential option for managing chemotherapy-induced diarrhea. This study aims to evaluate the efficacy and safety of probiotics in managing diarrhea induced by fluoropyrimidine or irinotecan-based chemotherapy in cancer patients. A literature search was conducted in Cochrane Library, PubMed, ScienceDirect, SciFinder, and Scopus in August 2023. Observational and prospective studies of cancer patients receiving 5-fluorouracil, capecitabine, or irinotecan were included. RevMan (version 5.4.1) was used for statistical analysis. The study protocol was registered in PROSPERO. Of the 9400 records, 24 and 14 studies were included in the systematic review and meta-analysis, respectively. Most studies provided a combination of probiotic strains to patients from the initiation to the completion of chemotherapy cycles. Probiotic supplementation significantly reduced all grade diarrhea (RR = 0.40; 95 % CI: 0.27, 0.60; P < 0.00001, I²: 0 %), nausea and vomiting (RR = 0.49; 95 % CI [0.37, 0.67]; P < 0.00001, I²: 0 %), bloating (RR = 0.27; 95 % CI [0.11, 0.69]; P = 0.006, I²: 0 %) and anorexia (RR = 0.62: 95 % CI [0.43, 0.90]; P = 0.01, I²: 39 %) compared to controls. Absolute risk reductions (ARR) ranged from 22.7 % to 28.5 %, with the number needed to treat (NNT) value of 3-5. Moreover, probiotics improved intestinal microbial balance and symptom scales of quality of life. Probiotic supplementation is a promising option to manage chemoradiotherapy-induced diarrhea without serious side effects in cancer patients receiving fluoropyrimidines or irinotecan-based regimens. Given the clinically meaningful ARR and favorable NNT values, probiotics may have a role in clinical practice. However, larger trials are needed to standardize probiotic strain, dosage, duration, and target patient subgroups. PROSPERO database (CRD42023473324).

Chemotherapy-induced diarrhea (CID) is a common adverse event in cancer patients, which, unless treated, may lead to drug discontinuation and treatment failure. Some probiotics such as Lactobacillus, Bifidobacterium, and Saccharomyces species have been gaining clinical attention in alleviating chemotherapy-induced adverse events including diarrhea. This comprehensive review provides an overview and discusses preventive approaches of probiotics with respect to CID in several types of cancers. The potential mechanisms of probiotics may comprise regulation of intestinal microbiota, modulation of immune functions, or reduction of proinflammatory cytokines. The efficacy and safety precautions of probiotics in immunocompromised cancer patients are discussed. The non-pharmacological strategy using probiotics could reduce the use of anti-diarrheal or antibiotic agents. Some individuals experienced shorter length of hospital stay, better gastrointestinal function, and reduced incidence of chemotherapy dose reduction after probiotic administration. Nonetheless, some studies failed to report the benefits of probiotics in certain patients. This review also highlights preventive protocols and therapeutic implications by considering the potential influencing factors, particularly types of probiotic strains, dosages of probiotics, duration of their administration, patients' tolerability, and variations in probiotic effects over the cancer stages.

Background: In burn patients, the profound effect of nutritional support on improved wound healing and a reduced rate of hospitalization and mortality has been documented. Fish oil as a primary source of omega-3 fatty acids in nutritional support may attenuate the inflammatory response and enhance immune function; however, unclear effects on the improvement of clinical outcomes in burn patients remain. Methods: The systematic literature review was conducted by searching the electronic databases: Cochrane Library, PubMed, ScienceDirect, and Scopus to assess the randomized controlled trials of nutritional support with omega-3 fatty acids compared to control diets in patients that presented with burns from any causes. Results: Seven trials were included in this meta-analysis. We found no significant differences in length of stay (LOS) (p = 0.59), mortality (p = 0.86), ventilation days (p = 0.16), gastrointestinal complications—e.g., constipation and diarrhea (p = 0.73)—or infectious complications—e.g., pneumonia and sepsis (p = 0.22)—between the omega-3-fatty-acid-receiving group and the control/other diets group. Conclusions: We did not find a benefit of omega-3 support in reducing the various complications, mortality and LOS in burn patients. Further studies are necessary to find the effect of nutritional support with omega-3 fatty acids over low-fat diets in this population.

There is limited evidence about the long-term changes in nutritional status among the elderly people living with human immunodeficiency virus (PLWH). We aimed to investigate the changes in nutritional status and related factors over 4 years in the elderly PLWH. The longitudinal study was conducted prospectively among 250 PLWH, 50 years of age and older, receiving antiretroviral therapy (ART). The Mini Nutritional Assessment (MNA) and Thai Depression Scale (TDS) to assess nutritional status and depression, respectively, were performed at the outpatient clinic both at baseline and 4-year follow-up. Majority were male (60.8%) with median age of 58 years. The median CD4 was 612.5 cells/mm ³ and 98% had HIV RNA <50 copies/mL. Median duration of ART was 20 years. Median body mass index was 23.1 kg/m ² . The most common ART were rilpivirine (45.2%) and dolutegravir (18.8%). Fifty-one patients (20.4%) deteriorated in nutritional status and mean MNA scores declined (25.8 vs. 24.8, p < .001) at follow-up period. In multivariate analysis, high TDS scores (odds ratio [OR], 1.33; 95% confidence interval [CI], 1.17–1.52), polypharmacy (OR, 1.35; 95% CI, 1.10–1.65), and high-density lipoprotein cholesterol (HDL-C) levels (OR, 1.04; 95% CI, 1.01–1.07) were associated factors of deterioration in nutritional status. In this 4-year longitudinal follow-up, 20% of the aging PLWH have deterioration of nutritional status. High TDS scores (depression), polypharmacy, and high HDL-C were significantly associated with declining nutritional status. Our findings highlight the importance of screening and monitoring nutritional and depression status in routine HIV treatment and care for geriatric HIV-infected population.
