BackgroundWithania somnifera (ashwagandha) is a prominent herb in Ayurveda. This study was conducted to examine the possible effects of ashwagandha root extract consumption on muscle mass and strength in healthy young men engaged in resistance training.MethodsIn this 8-week, randomized, prospective, double-blind, placebo-controlled clinical study, 57 young male subjects (18–50 years old) with little experience in resistance training were randomized into treatment (29 subjects) and placebo (28 subjects) groups. Subjects in the treatment group consumed 300 mg of ashwagandha root extract twice daily, while the control group consumed starch placebos. Following baseline measurements, both groups of subjects underwent resistance training for 8 weeks and measurements were repeated at the end of week 8. The primary efficacy measure was muscle strength. The secondary efficacy measures were muscle size, body composition, serum testosterone levels and muscle recovery. Muscle strength was evaluated using the 1-RM load for the bench press and leg extension exercises. Muscle recovery was evaluated by using serum creatine kinase level as a marker of muscle injury from the effects of exercise.ResultsCompared to the placebo subjects, the group treated with ashwagandha had significantly greater increases in muscle strength on the bench-press exercise (Placebo: 26.4 kg, 95 % CI, 19.5, 33.3 vs. Ashwagandha: 46.0 kg, 95 % CI 36.6, 55.5; p = 0.001) and the leg-extension exercise (Placebo: 9.8 kg, 95 % CI, 7.2,12.3 vs. Ashwagandha: 14.5 kg, 95 % CI, 10.8,18.2; p = 0.04), and significantly greater muscle size increase at the arms (Placebo: 5.3 cm2, 95 % CI, 3.3,7.2 vs. Ashwagandha: 8.6 cm2, 95 % CI, 6.9,10.8; p = 0.01) and chest (Placebo: 1.4 cm, 95 % CI, 0.8, 2.0 vs. Ashwagandha: 3.3 cm, 95 % CI, 2.6, 4.1; p < 0.001). Compared to the placebo subjects, the subjects receiving ashwagandha also had significantly greater reduction of exercise-induced muscle damage as indicated by the stabilization of serum creatine kinase (Placebo: 1307.5 U/L, 95 % CI, 1202.8, 1412.1, vs. Ashwagandha: 1462.6 U/L, 95 % CI, 1366.2, 1559.1; p = 0.03), significantly greater increase in testosterone level (Placebo: 18.0 ng/dL, 95 % CI, -15.8, 51.8 vs. Ashwagandha: 96.2 ng/dL, 95 % CI, 54.7, 137.5; p = 0.004), and a significantly greater decrease in body fat percentage (Placebo: 1.5 %, 95 % CI, 0.4 %, 2.6 % vs. Ashwagandha: 3.5 %, 95 % CI, 2.0 %, 4.9 %; p = 0.03).ConclusionThis study reports that ashwagandha supplementation is associated with significant increases in muscle mass and strength and suggests that ashwagandha supplementation may be useful in conjunction with a resistance training program.
Chronic stress has been associated with a number of illnesses, including obesity. Ashwagandha is a well-known adaptogen and known for reducing stress and anxiety in humans. The objective of this study was to evaluate the safety and efficacy of a standardized root extract of Ashwagandha through a double-blind, randomized, placebo-controlled trial. A total of 52 subjects under chronic stress received either Ashwagandha (300 mg) or placebo twice daily. Primary efficacy measures were Perceived Stress Scale and Food Cravings Questionnaire. Secondary efficacy measures were Oxford Happiness Questionnaire, Three-Factor Eating Questionnaire, serum cortisol, body weight, and body mass index. Each subject was assessed at the start and at 4 and 8 weeks. The treatment with Ashwagandha resulted in significant improvements in primary and secondary measures. Also, the extract was found to be safe and tolerable. The outcome of this study suggests that Ashwagandha root extract can be used for body weight management in adults under chronic stress.
Background Long‐COVID is emerging as a significant problem among individuals who recovered from COVID‐19. Scant information is available on the prevalence, characteristics, and risk factors for long‐COVID among people living with HIV (PLHIV). Setting A tertiary level, private, HIV clinic in western India. Methods A prospective, observational study was conducted to assess the prevalence of long‐COVID among PLHIV. Long‐COVID was defined as the presence of at least one symptom after 30 days of illness onset. A questionnaire for assessing general, cardiorespiratory, neuro‐psychiatric, and gastro‐intestinal symptoms was used to screen individuals with history of confirmed COVID‐19. Data on demographics, HIV‐related variables, comorbidities, and severity of COVID‐19 were abstracted from electronic medical records. Univariate and multivariate logistic regression were used to identify risk factors for long‐COVID. Results Ninety‐four PLHIV were screened for long‐COVID. Median (interquartile range [IQR]) age was 51 (47–56) years and 73.4% were males. The majority (76.6%) had a history of asymptomatic–mild COVID‐19 illness. The prevalence of long‐COVID was 43.6% (95% confidence interval [CI], 33.4–54.2). Moderate–severe COVID‐19 illness was significantly associated with long‐COVID (adjusted odds ratio, 4.7; 95% CI, 1.4–17.9; p = .016). Among individuals with long‐COVID, cough (22.3%) and fatigue (19.1%) were the commonest symptoms. The median (IQR) duration for resolution of symptoms was 15 (7–30) days. Ten individuals (10.6%) had persistent symptoms at a median of 109 days since the onset of COVID‐19. Conclusion Long‐COVID is common among PLHIV with moderate–severe acute COVID‐19 illness. There is a need for integration of long‐COVID diagnosis and care services within antiretroviral therapy clinics for PLHIV with COVID‐19.
BackgroundData on the renal safety of Tenofovir (TDF) in Low and Middle Income Countries (LMICs) is scarce. We compared development of various forms of renal impairment with use of TDF-containing antiretroviral therapy (ART) between a cohort from the Institute of Infectious Diseases (IID) Pune, Western India and the Royal Free Hospital (RFH) London, UK.MethodsThis is a retrospective analysis of change in estimated glomerular filtration rates (eGFRs) at 6, 12 and 24 months post TDF initiation using the Modification of Diet in Renal Disease (MDRD) equation. In people living with Human Immunodeficiency virus (PLHIV) with pre-TDF eGFR > 90 ml/min/1.73 m2 time to development of and factors associated with progression to eGFR < 60 ml/min/1.73 m2 were calculated using standard survival methods.ResultsA total of 574 (59% Caucasian) at the RFH, and 708 (100% Indian ethnicity) PLHIV from IID were included. Baseline median eGFR were similar; RFH 102 (IQR 89, 117), IID 100 (82, 119). At 24 months, mean (SD) decline in eGFR was -7(21) at RFH (p < 0.0001) and -7(40) at IID (p = 0.001). Amongst those with pre-TDF eGFR > 90 ml/min/1.73 m2 PLHIV at IID were more likely to develop an eGFR < 60 ml/min/1.73 m2 (aHR = 7.6 [95% CI 3.4, 17.4] p < 0.0001) and had a faster rate of progression estimated using Kaplan Meier methods. Risk factors included age (per 10 years older: aHR = 2.21 [1.6, 3.0] p < 0.0001) and receiving concomitant ritonavir boosted Protease Inhibitor (PI/r) (aHR = 2.4 [1.2, 4.8] p = 0.01).ConclusionsThere is higher frequency of treatment limiting renal impairment events amongst PLHIV receiving TDF in Western India. As TDF scale up progresses, programs need to develop capacity for monitoring and treatment of renal impairment associated with TDF.
Introduction: Renal disease is common amongst people living with HIV. However, there is limited information on the incidence and risk factors associated with renal dysfunction among this population in Asia. Methods: We used data from the TREAT Asia HIV Observational Database. Patients were included if they started antiretroviral therapy (ART) during or after 2003, had a serum creatinine measurement at ART initiation (baseline) and had at least two follow-up creatinine measurements taken ≥3 months apart. Patients with a baseline estimated glomerular filtration rate (eGFR) ≤60ml/min/1.73m2 were excluded. Chronic kidney disease was defined as two consecutive eGFR values ≤60ml/min/1.73m2 taken ≥3 months apart. Generalized estimating equations were used to identify factors associated with eGFR change. Competing risk regression adjusted for study site, age and sex, and cumulative_incidence plots were used to evaluate factors associated with CKD. Results: Of 2,547 patients eligible for this analysis, tenofovir was being used by 703 (27.6%) at baseline. Tenofovir use, high baseline eGFR, advanced HIV disease stage and low nadir CD4 were associated with a decrease in eGFR during follow up. CKD occurred at a rate of 3.4 per 1000 patient/years. Factors associated with CKD were tenofovir use, old age, low baseline eGFR, low nadir CD4, and protease inhibitor use. Conclusions: There is an urgent need to enhance renal monitoring and management capacity among at-risk groups in Asia and improve access to less nephrotoxic antiretrovirals.
