Among the symptoms of COVID-19 fever, general malaise, pain and aches, myalgia, fatigue, and headache can affect the quality of life of patients, even after the end of the acute phase of the infection and can be long lasting. The current treatment of these symptoms, also because COVID-19 patients have been asked not to use non-steroidal anti-inflammatory drugs (NSAIDs), in particular ibuprofen are often unsatisfactory. Among the above mentioned symptoms malaise and fatigue seem the most difficult to treat. In this case report we describe the use of kratom (Mitragyna speciosa) by a patient with confirmed COVID-19 infection. What we observed was a fast and sustained relieve of the above mentioned symptoms.

Kratom (Mitragyna speciosa Korth.) is traditionally used in Southeast Asia for its medicinal value and psychoactive properties. Nonetheless, cessation from regular kratom use is reported to cause unpleasant dose-dependent withdrawal symptoms. This study aims to evaluate the severity of pain and sleep problems following the cessation of kratom tea/juice consumption among regular kratom users. A total of 170 regular users were recruited through snowball sampling for this cross-sectional study. The Brief Pain Inventory (BPI) and Pittsburgh Sleep Quality Index (PSQI) scales were administered to assess the severity of pain and sleep problems. Most participants experienced moderate pain intensity (84%) and moderate pain interference (70%) during kratom cessation; 46% experienced more sleep problems during kratom cessation. Individuals who consumed ≥4 glasses of kratom tea/juice (about 76-115 mg of mitragynine) daily had higher odds of reporting some pain interference (OR: 2.0; CI: 1.04-3.93: p
The Use of Kratom (Mitragyna speciosa Korth.) Among People Who Co-use Heroin and Methamphetamine in Malaysia

Singh D, Narayanan S, Vicknasingam B, Prozialeck WC, Smith KE, Corazza O, et al.

J Addict Med, 2021 5 19;16(2):223-228.
PMID: 34001777 DOI: 10.1097/ADM.0000000000000876

OBJECTIVES: Kratom (Mitragyna speciosa Korth.), an indigenous medicinal plant, has been widely used as a traditional remedy in Southeast Asia. However, its combined consumption with other substances has received scarce attention. This study investigates the use of kratom among adults with a history of using heroin and methamphetamine in Malaysia.
METHODS: A total of 332 patients who were mandated to undergo drug rehabilitation participated in this cross-sectional study. The study data were collected through face-to-face interviews using a semi-structured questionnaire.
RESULTS: The majority were males (95%, n = 314/332) and Malays (98%, n = 325/332) with a mean age of 32.3 years (SD = 9.16). Over two thirds of the respondents used kratom to alleviate heroin withdrawal symptoms and to reduce methamphetamine intake; 59% used it as a substitute for heroin and methamphetamine. A similar proportion used kratom to reduce heroin intake (58%), while only 15% used it for its euphoric effects. Multivariate analysis showed that previous attendees of government rehabilitation programs had lower odds of using kratom as a heroin substitute.
CONCLUSIONS: The potential of kratom to alleviate heroin withdrawal symptoms, and to reduce methamphetamine and heroin intake, among people who co-use heroin and methamphetamine warrants further research.
Self-reported prevalence and severity of opioid and kratom (Mitragyna speciosa korth.) side effects

Saref A, Suraya S, Singh D, Grundmann O, Narayanan S, Swogger MT, et al.

J Ethnopharmacol, 2019 Jun 28;238:111876.

ETHNOPHARMACOLOGICAL RELEVANCE: Mitragyna speciosa (Korth.) is a traditional medicinal plant widely used in Southeast Asia for its opioid-like effects. Although kratom produces analgesia through binding of mitragynine and other alkaloids at the mu-opioid receptor (MOR), the association of long-term kratom use with adverse opioid-like effects remains unknown.
AIM OF THE STUDY: To determine the self-reported prevalence and severity of opioid-related adverse effects after kratom initiation in a cohort of illicit opioid users.
MATERIALS AND METHODS: A total of 163 illicit opioid users with current kratom use history were recruited through convenience sampling from the northern states of Peninsular Malaysia. Face-to-face interviews were conducted using a semi-structured questionnaire.
RESULTS: Respondents were all males, majority Malays (94%, n = 154/163), with a mean age of 37.10 years (SD = 10.9). Most were single (65%, n = 106/163), had 11 years of education (52%, n = 85/163) and employed (88%, n = 144/163). Half reported using kratom for over >6 years (50%, n = 81/163), and 41% consumed >3 glasses of kratom daily (n = 67/163). Results from Chi-square analysis showed kratom initiation was associated with decreased prevalence of respiratory depression, constipation, physical pain, insomnia, depression, loss of appetite, craving, decreased sexual performance, weight loss and fatigue.
CONCLUSIONS: Our findings indicate that kratom initiation (approximately 214.29 mg of mitragynine) was associated with significant decreases in the prevalence and severity of opioid adverse effects.

This study sought to determine the relationship between kratom (Mitragyna speciosa) initiation and regular consumption of illicit drugs and HIV risk behaviors in a cohort of illicit drug users in Malaysia. 260 illicit drug users with current kratom use were recruited through convenience sampling for this cross-sectional study. All were male, with the majority being Malays (95%, n = 246/260). Results suggest that kratom initiation was associated with significant decrease in the regular use of heroin (odds ratio (OR) = 0.50, 95% confidence interval (CI): 0.40- 0.72; p = .0001), methamphetamine (OR = 0.23, CI: 0.16- 0.35; p < .0001), and amphetamine (OR = 0.17, CI: 0.09- 0.34; p < .0001). Kratom initiation was also associated with reduction in regular HIV risk behaviors such as having sex with sex workers (OR = 0.20, CI: 0.12-0.32; p < .0001), using drugs before sexual intercourse (OR = 0.20, CI: 0.13- 0.31; p < .0001), injecting behaviors (OR = 0.10, CI: 0.04- 0.25; p < .0001), sharing of injection equipment (OR = 0.13, CI: 0.04- 0.43; p < .0001), and injecting with other injection drug users (IDUs) (OR = 0.07, CI: 0.02- 0.24; p < .0001).

Kratom (Mitragyna speciosa), an indigenous medicinal plant of Southeast Asia, is believed to be harmful. We compared the perceptions toward kratom use among kratom users and non-users in Malaysia. 356 respondents (137 kratom users and 219 non-users) were recruited for this cross-sectional study. The majority of respondents were male (60%, n = 212/356), Malays (88%), and 51% were ≥37 years old. Non-users showed higher unadjusted odds of reporting a perception that kratom use can cause addiction (OR = 6.72, CI: 3.91-11.54, p
Fulltext Kratom policy: The challenge of balancing therapeutic potential with public safety

Kratom (Mitragyna speciosa) is a tree-like plant indigenous to Southeast Asia. Its leaves, and the teas brewed from them have long been used by people in that region to stave off fatigue and to manage pain and opioid withdrawal. Evidence suggests kratom is being increasingly used by people in the United States and Europe for the self-management of opioid withdrawal and treatment of pain. Recent studies have confirmed that kratom and its chemical constituents have potentially useful pharmacological actions. However, there have also been increasing numbers of reports of adverse effects resulting from use of kratom products. In August 2016, the US Drug Enforcement Administration announced plans to classify kratom and its mitragynine constituents as Schedule I Controlled Substances, a move that triggered a massive response from pro-kratom advocates. The debate regarding the risks, and benefits and safety of kratom continues to intensify. Kratom proponents tout kratom as a safer and less addictive alternative to opioids for the management of pain and opioid addiction. The anti-kratom faction argues that kratom, itself, is a dangerous and addictive drug that ought to be banned. Given the widespread use of kratom and the extensive media attention it is receiving, it is important for physicians, scientists and policy makers to be knowledgeable about the subject. The purpose of this commentary is to update readers about recent developments and controversies in this rapidly evolving area. All of the authors are engaged in various aspects of kratom research and it is our intention to provide a fair and balanced overview that can form the basis for informed decisions on kratom policy. Our conclusions from these analyses are: (a) User reports and results of preclinical studies in animals strongly suggest that kratom and its main constituent alkaloid, mitragynine may have useful activity in alleviating pain and managing symptoms of opioid withdrawal, even though well-controlled clinical trials have yet to be done. (b) Even though kratom lacks many of the toxicities of classic opioids, there are legitimate concerns about the safety and lack of quality control of purported "kratom" products that are being sold in the US. (c) The issues regarding the safety and efficacy of kratom and its mitragynine constituent can only be resolved by additional research. Classification of the Mitragyna alkaloids as Schedule I controlled substances would substantially impede this important research on kratom.
Current and Future Potential Impact of COVID-19 on Kratom (Mitragyna speciosa Korth.) Supply and Use

Kratom (Mitragyna speciosa Korth., Rubiaceae) is native to and has traditional use in Southeast Asia. The number of kratom users outside of Southeast Asia has increased significantly in recent decades with use spreading to the Unites States (US) and Europe. Because of its reputed opioid-like psychoactive effects at higher doses, kratom has been regulated in several countries and is subject to an import ban by the US Food and Drug Administration. Nonetheless, in the US it is estimated that 10-15 million people consume kratom primarily for the self-treatment of pain, psychiatric disorders, to mitigate withdrawal from or dependence on opioids, and to self-treat opioid use disorder or other substance use disorders (SUDs). Due to the global COVID-19 pandemic, a shortage in the supply of kratom products may place unexpected burdens on kratom users, potentially influencing some who use kratom for SUD self-treatment to regress to harmful drug use, hence increasing the likelihood of adverse outcomes, including overdose. Inadequate treatment, treatment barriers, and increases in the sales of adulterated kratom products on the internet or in convenience stores could exacerbate circumstances further. Although there are currently no verified indications of kratom scarcity, researchers and clinicians should be aware of and remain vigilant to this unanticipated possibility.
