RESUMO
Several follow-up studies have found that COVID-19 (coronavirus disease 2019) patients had persistent symptoms after discharge. Gut microbiota play an important role in human health and immune responses. Therefore, this study investigated the gut microbiota of recovered COVID-19 patients and the correlations between gut microbiota and persistent symptoms after discharge. Stool samples were collected from 15 recovered healthcare workers (HCWs) with COVID-19 at three months after discharge, in addition, stool samples were collected from 14 healthy controls (HCs) to perform 16S rRNA gene sequencing between May and July 2020. Compared with HCs, recovered HCWs had reduced bacterial diversity at three months after discharge, with a significantly higher relative abundance of opportunistic pathogens, and a significantly lower relative abundance of beneficial bacteria. In addition, Escherichia unclassified was positively correlated with persistent symptoms at three months after discharge, including fatigue (r = 0.567, p = 0.028), chest tightness after activity (r = 0.687, p = 0.005), and myalgia (r = 0.523, p = 0.045). Intestinibacter bartlettii was positively correlated with anorexia (r = 0.629, p = 0.012) and fatigue (r = 0.545, p = 0.036). However, Faecalibacterium prausnitzii was negatively correlated with chest tightness after activity (r = -0.591, p = 0.02), and Intestinimonas butyriciproducens was negatively correlated with cough (r = -0.635, p = 0.011). In conclusion, the gut microbiota of recovered HCWs with COVID-19 at three months after discharge was different from that of HCs, and altered gut microbiota was correlated with persistent symptoms after discharge, highlighting that gut microbiota may play an important role in the recovery of patients with COVID-19.

Intense and excessive exercise-induced fatigue has become an important health issue and can damage intestinal health. Deer blood, as a food byproduct with nutritional value, has been found to restore physical strength. However, little is known about the antifatigue effect of fermented deer blood (FDB) on intense exercise mice. The purpose of the present study is to investigate the antifatigue effect of FDB, and whether this effect is correlated with the altered small intestinal microbiota and metabolites in exercise mice. In this study, 5-week-old male C57BL/6J mice are given treadmill exercise with or without FDB supplementation (30 and 150 mg/kg/d) for 3 weeks. FDB significantly reduces metabolic byproduct accumulation, liver and intestinal damage, and enhances glycogen storage and antioxidant capacity in intense exercise mice. Moreover, FDB restructures the small intestinal microbiota by increasing the abundance of probiotics and butyric acid producing bacteria and decreasing the abundance of pathogenic bacteria. FDB also regulates the levels of metabolites involved in TCA cycle and amino acid metabolism in urine and small intestine content. Correlation analysis shows that FDB-modulated microbiota is highly associated with its antifatigue effect. FDB may ameliorate fatigue and intestinal injury through targeting small intestinal microbiota.

Fatigue is the most prevalent symptom of cancer and its treatments. Changes in the intestinal microbiome have been identified in chronic fatigue syndrome and other neuropsychiatric disorders, and cancer patients. However, the association between intestinal microbiome and fatigue in patients with advanced cancers has not been evaluated. Understanding the connection between intestinal microbiome and fatigue will provide interventional and therapeutic opportunities to manipulate the microbiome to improve fatigue and other patients' reported outcomes. In this project, we aimed to identify associations between microbiome composition and fatigue in advanced cancer patients. In this cross-sectional observational study at a tertiary cancer care center, we included 88 patients with advanced, metastatic, unresectable cancers who were in a washout period from chemotherapy. We measured fatigue using the MD Anderson Symptom Inventory-Immunotherapy fatigue score, and used 16srRNA to analyze intestinal microbiome. Using correlation analysis we found that Eubacterium hallii was negatively associated with fatigue severity scores (r = - 0.30, p = 0.005), whereas Cosenzaea was positively associated with fatigue scores (r = 0.33, p = 0.0002). We identified microbial species that exhibit distinct composition between high-fatigued and low-fatigued cancer patients. Further studies are warranted to investigate whether modulating the microbiome reduces cancer patients' fatigue severity and improves their quality of life.

Long-term cognitive problems and fatigue after adequately treated neuroborreliosis has caused uncertainty and debate among patients and health care workers for years. Despite several studies, the prevalence, cause and severity of such complaints are still not clarified. More knowledge about cognitive function, fatigue and MRI findings in the acute phase of neuroborreliosis could possibly contribute to clarification. In the current study, we therefore aimed to address this. Patients with well-characterized acute neuroborreliosis (n = 72) and a matched control group (n = 68) were screened with eight subtests from three different neuropsychological test batteries assessing attention, working memory and processing speed, and with Fatigue Severity Scale. Fazekas score was used to grade white matter hyperintensities on MRI. We found no differences in mean scores on the neuropsychological tests between the groups. The patient group reported significantly higher level of fatigue (Fatigue Severity Scale: 4.8 vs. 2.9, p < .001). There was no significant difference in Fazekas score between the groups. Neuroborreliosis does not seem to affect cognitive functions in the acute state of the disease, while fatigue is common.

PURPOSE: To examine a) whether there are significant differences in the severity of symptoms of fatigue, sleep disturbance, or depression between patients with rectal cancer who develop co-occurring symptoms and those with no symptoms before and at the end of chemotherapy and radiation therapy (CRT); b) differences in gut microbial diversity between those with co-occurring symptoms and those with no symptoms; and c) whether before-treatment diversity measurements and taxa abundances can predict co-occurrence of symptoms. METHODS: Stool samples and symptom ratings were collected from 31 patients with rectal cancer prior to and at the end of (24-28 treatments) CRT. Descriptive statistics were computed and the Mann-Whitney U test was performed for symptoms. Gut microbiome data were analyzed using R's vegan package software. RESULTS: Participants with co-occurring symptoms reported greater severity of fatigue at the end of CRT than those with no symptoms. Bacteroides and Blautia2 abundances differed between participants with co-occurring symptoms and those with no symptoms. Our random forest classification (unsupervised learning algorithm) predicted participants who developed co-occurring symptoms with 74% accuracy, using specific phylum, family, and genera abundances as predictors. CONCLUSION: Our preliminary results point to an association between the gut microbiota and co-occurring symptoms in rectal cancer patients and serves as a first step in potential identification of a microbiota-based classifier.

We aimed to evaluate the anti-fatigue effects of the oyster polypeptide (OP) fraction and its regulatory effect on the gut microbiota in mice. Our exhaustive swimming experiment showed that the swimming time of the low-, middle- and high-dose groups of the OP fraction was increased by 1.82, 2.18 and 2.44 times compared with the control group, respectively. Besides, the liver glycogen levels of the three groups were increased by 19.3%, 42.02% and 65.07%, while the lactate levels were decreased by 18.85%, 21.18% and 28.74%, respectively. Moreover, administration of the OP fraction upregulated the expressions of PEPCK and AMPK, but downregulated the TNF-α expression. Correlation analysis between the gut microbiota and fatigue-related biochemical indicators showed that Faecalibacterium, Desulfovibri and Intestinibacter were negatively correlated with the swimming time, blood lactate, blood urea nitrogen, liver glycogen and muscle glycogen, while Yaniella and Romboutsia were positively correlated. Therefore, the OP fraction had anti-fatigue effects, and could regulate the abundance of gut microbiota and maintain its balance.

Human brucellosis, one of the most common zoonoses worldwide, rarely occurs in Japan, and only a few chronic cases have been reported. We herein report the case of a 39-year-old Japanese woman with chronic human brucellosis, considered a Brucella canis infection, that persisted for 19 years. Her medical history and fever pattern suggested chronic brucellosis, and the diagnosis was made based on the results of a serum tube agglutination test (SAT). After undergoing combination therapy with streptomycin and doxycycline, she achieved symptomatic relief and showed negative SAT results. Even in non-endemic areas, chronic brucellosis is an important differential diagnosis in patients with long-term persistent fatigue or a fever.

We studied dampness and mold in China in relation to rhinitis, ocular, throat and dermal symptoms, headache and fatigue. A questionnaire study was performed in six cities including 36 541 randomized parents of young children. Seven self-reported signs of dampness were evaluated. Multilevel logistic regression models were used to calculate odds ratios (ORs). Totally, 3.1% had weekly rhinitis, 2.8% eye, 4.1% throat and 4.8% skin symptoms, 3.0% headache and 13.9% fatigue. Overall, 6.3% of the homes had mold, 11.1% damp stains, 35.3% damp bed clothing, 12.8% water damage, 45.4% window pane condensation, 11.1% mold odor, and 37.5% humid air. All dampness signs were associated with symptoms (ORs from 1.2 to 4.6; P < 0.001), including rhinitis (ORs from 1.4 to 3.2; P < 0.001), and ORs increased by number of dampness signs. The strongest associations were for mold odor (ORs from 2.3 to 4.6) and humid air (ORs from 2.8 to 4.8). Associations were stronger among men and stronger in Beijing as compared to south China. In conclusion, dampness and mold are common in Chinese homes and associated with rhinitis and ocular, throat and dermal symptoms, headache and fatigue. Men can be more sensitive to dampness and health effects of dampness can be stronger in northern China.

Importance: Multiple erythema migrans (MEM) has been suggested as a risk factor for unfavorable antibiotic treatment outcome compared with solitary erythema migrans (EM). However, no direct comparison of early Lyme borreliosis manifested as MEM with solitary EM has been undertaken. Objective: To investigate the potential differences in clinical course and treatment outcome between MEM and solitary EM. Design, Setting, and Participants: This prospective cohort study was conducted from June 1, 2010, to October 31, 2015, at the University Medical Center Ljubljana, Slovenia. Data were analyzed from June 1, 2017, to January 3, 2018. Of the 778 consecutive adult patients with early Lyme borreliosis evaluated, 200 patients with MEM and 403 patients with solitary EM were enrolled. Patients were asked to refer a family member or a friend of similar age (±5 years) without a history of Lyme borreliosis to serve as a control participant. Clinical course and posttreatment outcome of MEM were compared with those of solitary EM. Outcome was assessed at 14 days and at 2, 6, and 12 months after enrollment. At each visit, patients completed a written questionnaire about their symptoms; controls completed the same questionnaire. Nonspecific symptoms reported by patients and controls without a history of Lyme borreliosis were compared. Main Outcomes and Measures: The proportion of patients with incomplete response at 12 months after enrollment and the associated 2-sided 95% CI for the difference between MEM and solitary EM were estimated using the normal approximation with continuity correction. Results: A total of 200 patients with MEM and 403 patients with solitary EM were included. Among the 200 patients with MEM, 94 (47.0%) were males and 106 (53.0%) were females, with a median (interquartile range [IQR]) age of 47 (35-58) years. Among the 403 patients with solitary EM, 182 (45.2%) were males and 221 (54.8%) were females, with a median (IQR) age of 55 (42-62) years. Patients with MEM reported Lyme borreliosis-associated constitutional symptoms at enrollment more often than those with solitary EM (93 [46.5%]; 95% CI, 39.4-53.7 vs 96 [23.8%]; 95% CI, 19.7-28.3; P < .001). During the initial 6 months after treatment, the proportion of patients with incomplete response was higher in the MEM group than in the solitary EM group (14 days: 62 of 193 [32.1%] vs 72 of 391 [18.4%]; P < .001; 2 months: 38 of 193 [19.7%] vs 55 of 394 [14.0%]; P = .28; 6 months: 29 of 182 [15.9%] vs 31 of 359 [8.6%]; P = .02). However, at the 12-month visit, the outcome was comparable: 10 of 170 (5.9%) patients with MEM vs 20 of 308 (6.5%) patients with solitary EM showed incomplete response (-0.6; 95% CI, -5.5 to 4.3; P = .95). The frequency of nonspecific symptoms in patients was similar to that in controls. Conclusions and Relevance: The long-term outcome at 12 months after treatment was comparable, regardless of dissemination. Follow-up of at least 12 months after treatment is thus recommended for future studies that investigate post-Lyme borreliosis symptoms.

The present study evaluated the potential beneficial effect of kefir (KF) against fatigue. Furthermore, the composition of the gut microbiota is related to health benefits in the host; therefore, the study also investigated the effect of KF on the gut microbiota composition. Male ICR mice from four groups (n = 8 per group) were orally administered KF once daily for four weeks at 0, 2.15, 4.31, and 10.76 g/kg/day and were designated as the vehicle, KF-1X, KF-2X, and KF-5X groups, respectively. The gut microbiota was analyzed using 16S rRNA gene sequencing. The results showed a significant clustering of cecum after treatment in the vehicle, KF-1X, KF-2X, and KF-5X groups. The KF-2X and KF-5X groups showed a decreased Firmicutes/Bacteroidetes ratio compared with the vehicle group. In addition, anti-fatigue activity and exercise performance were evaluated on the basis of exhaustive swimming time, forelimb grip strength, and levels of serum lactate, ammonia, glucose, blood urea nitrogen (BUN), and creatine kinase (CK) after a swimming exercise. The exhaustive swimming time for the KF-1X, KF-2X, and KF-5X groups was significantly longer than that for the vehicle group, and the forelimb grip strength of the KF-1X, KF-2X, and KF-5X groups was also significantly higher than that of the vehicle group. KF supplementation also decreased serum lactate, ammonia, BUN, and CK levels after the swimming test. However, tissue glycogen content, an important energy source for exercise, increased significantly with KF supplementation. Thus, KF supplementation can alter the gut microbiota composition, improve performance, and combat physical fatigue.

OBJECTIVES: To develop a patient-reported outcome (PRO) questionnaire for symptoms of Clostridium difficile infection (CDI) following the US Food and Drug Administration PRO guidelines. METHODS: Patients' experiences of CDI symptoms were elicited in open-ended discussions with patients and nurses at five US sites (stage 1). A draft PRO measure was developed after demonstration of concept saturation. Two rounds of cognitive interviews were conducted with patients at three US sites (stage 2), with revision of the draft measure after each round. All patients were 18 years or older, with confirmed CDI. The study was conducted with input from a panel of five CDI experts in Europe and North America. RESULTS: Stage 1 included interviews with 18 patients and supplementary interviews with 6 nurses; 16 additional patients were interviewed in stage 2. Patients were representative of the general CDI population and were diverse in age, sex, and disease severity. Concept saturation was reached in stage 1. Items were organized in a draft conceptual framework with five hypothesized domains: diarrhea, abdominal discomfort, tiredness, lightheadedness, and other symptoms. Stage 2 demonstrated initial content validity of the 13-item draft daily diary (CDI-DaySyms). Participants reported that the questions were clear, relevant, and comprehensive. They were able to use the instructions to complete the diary correctly and considered the 24-hour recall period appropriate. CONCLUSIONS: The CDI-DaySyms captures symptoms relevant to patients undergoing CDI, demonstrating initial content validity. Final content and psychometric validity are being evaluated in a substudy comprising patients from two ongoing international clinical trials (ClinicalTrials.gov identifiers NCT01987895 and NCT01983683).

INTRODUCTION/BACKGROUND: Mycobacterium ulcerans (also known as Buruli ulcer) disease is a rare skin disease which is prevalent in rural communities in the tropics mostly in Africa. Mortality rate is low, yet morbidity and consequent disabilities affect the quality of life of sufferers. AIMS: The aim of this paper is to use the grounded theory method to explore the support needs of people living with the consequences of Buruli ulcer in an endemic rural community in Ghana. METHODS: We used the grounded theory research approach to explore the experiences of people living with Mycobacterium ulcerans in a rural district in Ghana and provide a basis to understand the support needs of this group. RESULTS: The key support needs identified were: functional limitations, fear and frequency of disease recurrence, contracture of limbs and legs, loss of sensation and numbness in the affected body area, lack of information from health professionals about self-care, feeling tired all the time, insomnia, lack of good diet, lack of access to prostheses, having to walk long distances to access health services, and loss of educational opportunities. DISCUSSIONS: The study discusses how the systematically derived qualitative data has helped to provide a unique insight and advance our understanding of the support needs of people living with BU and how they live and attempt to adapt their lives with disability. We discuss how the availability of appropriate interventions and equipment could help them self-manage their condition and improve access to skin care services. CONCLUSIONS: The support needs of this vulnerable group were identified from a detailed analysis of how those living with BU coped with their lives. A key issue is the lack of education to assist self-management and prevent deterioration. Further research into the evaluation of interventions to address these support needs is necessary including self-management strategies.

Tetanus is a rare disease in industrialized countries, largely due to the highly protective effect of immunization. We present a case of tetanus in a formerly preterm infant with myelomeningocele repaired in utero, who presented at 44 days of age with poor feeding, lethargy, and increased tone. His symptoms progressed despite a course of antibiotics for presumed meningitis. At 73 days of age (on 29th day of hospitalization), a clinical diagnosis of tetanus was made based on the presence of risus sardonicus, trismus, and generalized hypertonicity. Consequently, tetanus immune globulin, muscle relaxants, and metronidazole were administered. Five months later, the infant has had complete resolution of the hypertonicity, has regained normal jaw movement and swallowing, and is regaining oral feeding skills. This case involved a delay in diagnosis despite clinical symptoms and signs classic, in retrospect, for tetanus, highlighting the importance of recognizing the constellation of symptoms that should lead us to consider this rare diagnosis.

Tuberculosis (TB) remains one of the leading infectious causes of death throughout the world. Extrapulmonary forms, namely adrenalitis and prostatitis, are rare presentations of TB and pose a difficult diagnostic challenge, given their non-specific manifestations. The authors present a case of a 42-year-old man with long-standing symptoms of fatigue, anorexia, weight loss, nightly fever and sudoresis. He also suffered from sporadic vomiting and episodic hypotension, and had skin hyperpigmentation, as well as frequent urination, perineal discomfort and pain at ejaculation. Laboratory investigation confirmed primary adrenal failure. On CT scan there were two hypodense right adrenal nodules and bilateral lung condensations with a tree-in-bud pattern. Another hypodense nodule was seen in the prostate. TB was diagnosed by isolatingMycobacterium tuberculosisfollowing cultures of bronchoalveolar lavage, bronchial secretions, urine and ejaculate. Antibacillary treatment resolved the infectious lesions but the patient remained on corticosteroid replacement therapy for ongoing adrenal failure.

Q fever endocarditis is a rare, culture negative endocarditis caused by Coxiella burnetii, a spore-forming gram negative coccobacillus. Presenting symptoms can be very non-specific; thus, diagnosis may be delayed. We present a case of a 65-year-old male patient with history of aortic aneurysm who complained of chronic fatigue. He was found to have aortic valve vegetation on routine echocardiography. Q fever endocarditis was diagnosed based on elevated Q fever serology; there was absence of fever. This case illustrated a rare, under-recognized and atypical manifestation of Q fever endocarditis. We would like to encourage physicians of rural states like South Dakota to remain vigilant when it comes to screening for the suspected cases of Q fever, specifically in cases of unexplained fatigue and valvulopathy.

Cat scratch disease is an infectious disorder transmitted by cats that typically affects children and young adults. Immunosuppression is a well-known risk factor for the development of severe and atypical forms of the disease; hence it is under-diagnosed in patients with compromised immunity. We are reporting the first case of cat scratch disease, which presented as fever and fatigue, in a patient with systemic lupus erythematosus while receiving immunosuppressant therapy after a kidney transplant.

Patients who present with severe intractable apparently idiopathic fatigue accompanied by profound physical and or cognitive disability present a significant therapeutic challenge. The effect of psychological counseling is limited, with significant but very slight improvements in psychometric measures of fatigue and disability but no improvement on scientific measures of physical impairment compared to controls. Similarly, exercise regimes either produce significant, but practically unimportant, benefit or provoke symptom exacerbation. Many such patients are afforded the exclusionary, non-specific diagnosis of chronic fatigue syndrome if rudimentary testing fails to discover the cause of their symptoms. More sophisticated investigations often reveal the presence of a range of pathogens capable of establishing life-long infections with sophisticated immune evasion strategies, including Parvoviruses, HHV6, variants of Epstein-Barr, Cytomegalovirus, Mycoplasma, and Borrelia burgdorferi. Other patients have a history of chronic fungal or other biotoxin exposure. Herein, we explain the epigenetic factors that may render such individuals susceptible to the chronic pathology induced by such agents, how such agents induce pathology, and, indeed, how such pathology can persist and even amplify even when infections have cleared or when biotoxin exposure has ceased. The presence of active, reactivated, or even latent Herpes virus could be a potential source of intractable fatigue accompanied by profound physical and or cognitive disability in some patients, and the same may be true of persistent Parvovirus B12 and mycoplasma infection. A history of chronic mold exposure is a feasible explanation for such symptoms, as is the presence of B. burgdorferi. The complex tropism, life cycles, genetic variability, and low titer of many of these pathogens makes their detection in blood a challenge. Examination of lymphoid tissue or CSF in such circumstances may be warranted.
