Health sequelae of human cryptosporidiosis in industrialised countries: a systematic review.

BACKGROUND: Cryptosporidium is a protozoan parasite which is a common cause of gastroenteritis worldwide. In developing countries, it is one of the most important causes of moderate to severe diarrhoea in young children; in industrialised countries it is a cause of outbreaks of gastroenteritis associated with drinking water, swimming pools and other environmental sources and a particular concern in certain immunocompromised patient groups, where it can cause severe disease. However, over recent years, longer-term sequelae of infection have been recognised and a number of studies have been published on this topic. The purpose of this systematic review was to examine the literature in order to better understand the medium- to long-term impact of cryptosporidiosis. METHODS: This was a systematic review of studies in PubMed, ProQuest and Web of Science databases, with no limitations on publication year or language. Studies from any country were included in qualitative synthesis, but only those in industrialised countries were included in quantitative analysis. RESULTS: Fifteen studies were identified for qualitative analysis which included 3670 Cryptosporidium cases; eight studies conducted in Europe between 2004-2019 were suitable for quantitative analysis, including five case-control studies. The most common reported long-term sequelae were diarrhoea (25%), abdominal pain (25%), nausea (24%), fatigue (24%) and headache (21%). Overall, long-term sequelae were more prevalent following infection with Cryptosporidium hominis, with only weight loss and blood in stool being more prevalent following infection with Cryptosporidium parvum. Analysis of the case-control studies found that individuals were 6 times more likely to report chronic diarrhoea and weight loss up to 28 months after a Cryptosporidium infection than were controls. Long-term abdominal pain, loss of appetite, fatigue, vomiting, joint pain, headache and eye pain were also between 2-3 times more likely following a Cryptosporidium infection. CONCLUSIONS: This is the first systematic review of the long-term sequelae of cryptosporidiosis. A better understanding of long-term outcomes of cryptosporidiosis is valuable to inform the expectations of clinicians and their patients, and public health policy-makers regarding the control and prevention of this infection.

Effects of web-based education and counselling for patients with systemic lupus erythematosus: self-efficacy, fatigue and assessment of care.

OBJECTIVE: The aim of this study was to determine the effect of web-based education and counselling for patients with systemic lupus erythematosus on self-efficacy, fatigue and assessment of care. METHODS: The study was conducted as a randomized controlled trial. The study sample consisted of 80 patients divided into two groups: the experimental group (n = 40) and a control group (n = 40). Randomization was performed by simple random sampling. At the beginning of the study (month 0), data-collection forms were administered to both groups. Web-based education was carried out for the first three months, and counselling and information updates were given for the next three months for the experimental group. In the intervention process, the control group just received standard care. After six months, data-collection forms were administered to both groups again. RESULTS: The mean age of the participants in the experimental and control groups was 35.58 ± 8.40 years and 39.00 ± 12.71 years, respectively. In both groups, 95% of patients were women. Wilcoxon's test was used for within-group comparisons before and after the study. The Mann-Whitney U-test was used to evaluate the difference between the two groups before the intervention and between the two groups after the intervention. We found that there was a significant improvement in fatigue, self-efficacy and assessment of chronic illness care in the experimental group at the end of the study (p < 0.05). CONCLUSIONS: The intervention had a positive effect on self-efficacy, fatigue and satisfaction with chronic illness. In accordance with the results, similar studies should be conducted for different patient groups in order to strengthen the results.

Acupuncture for chronic fatigue syndrome and idiopathic chronic fatigue: a multicenter, nonblinded, randomized controlled trial.

BACKGROUND: The causes of chronic fatigue syndrome (CFS) and idiopathic chronic fatigue (ICF) are not clearly known, and there are no definitive treatments for them. Therefore, patients with CFS and ICF are interested in Oriental medicine or complementary and alternative medicine. For this reason, the effectiveness of complementary and alternative treatments should be verified. We investigated the effectiveness of two forms of acupuncture added to usual care for CFS and ICF compared to usual care alone. METHODS: A three-arm parallel, non-blinded, randomized controlled trial was performed in four hospitals. We divided 150 participants into treatment and control groups at the same ratio. The treatment groups (Group A, body acupuncture; Group B, Sa-am acupuncture) received 10 sessions for 4 weeks. The control group (Group C) continued usual care alone. The primary outcome was the Fatigue Severity Scale (FSS) at 5 weeks after randomization. Secondary outcomes were the FSS at 13 weeks and a short form of the Stress Response Inventory (SRI), the Beck Depression Inventory (BDI), the Numeric Rating Scale (NRS), and the EuroQol-5 Dimension (EQ-5D) at 5 and 13 weeks. RESULTS: Group A showed significantly lower FSS scores than Group C at 5 weeks (P = 0.023). SRI scores were significantly lower in the treatment groups than in the control group at 5 (Group A, P = 0.032; B, P <0.001) and 13 weeks (Group A, P = 0.037; B, P <0.001). Group B showed significantly lower BDI scores than Group C at 13 weeks (P = 0.007). NRS scores from the treatment groups were significantly reduced compared to control at 5 (Group A and B, P <0.001) and 13 weeks (Group A, P = 0.011; B, P = 0.002). CONCLUSIONS: Body acupuncture for 4 weeks in addition to usual care may help improve fatigue in CFS and ICF patients.

Fatigue and acute/chronic anaemia.

UNLABELLED: Fatigue in patients with gastrointestinal (GI) diseases can be caused by several conditions and anaemia is one of them. Anaemia can be caused by acute GI bleeding, or it can appear in relation to more chronic conditions: iron deficiency anaemia (IDA) and/or anaemia of chronic disease (ACD). Acute anaemia due to acute upper GI bleedings (AUGIB) is often treated with blood transfusions and/or oral iron supplementations. The need for blood transfusions prior to endoscopic intervention has been well described in guidelines. However, guidelines for the monitoring and treatment of anaemia in patients after nonvariceal AUGIB are generally lacking. A retrospective study showed that more than 80% of patients were discharged from hospital with anaemia and less than 20% of them were recommended iron supplementations. Chronic anaemia in inflammatory bowel diseases (IBD) is well known. Anaemia can be caused by deficiency conditions (iron, folic acid or vitamin B12); chronic bleeding; inflammation or medication (or a combination of these). Fatigue in IBD is found in 40% of IBD patients, even with disease in remission. The PhD dissertation is based on two studies. 1. A randomised placebo controlled trial where patients were allocated to iron supplementation (oral or intravenous) or placebo. Patients with nonvariceal AUGIB and anaemia were included in the study (N = 97). The primary follow-up time was 13 weeks, followed by additional three months follow-up. 2. A cross-sectional study including Scandinavian outpatients with IBD. Five hospitals in Denmark, Norway and Sweden included consecutively 5% of their cohort of patients with IBD (N = 429). The aims were: 1. To investigate the effect of iron supplementation in patients who had anaemia after endoscopic intervention for AUGIB. Furthermore, to investigate the health-related quality of life (HRQoL) and fatigue in these patients. 2. To determine the prevalence and type of anaemia, iron deficiency (ID) and fatigue in an unselected group of Scandinavian IBD outpatients. RESULTS: 1. Using haemoglobin (Hb) as a marker, the results of the intervention study on anaemic AUGIB patients showed that iron supplementations were superior to no treatment and intravenous iron was more effective to fill the patients iron stores than was oral iron. No differences in the Hb levels were found between the oral and intravenous iron groups after 13 weeks. Data on HRQoL and fatigue showed in general an improvement during the follow-up period. The improvement was not solely linked to treatment of anaemia. 2. The overall prevalence of anaemia in the Scandinavian population of IBD outpatients was 19%. Most patients had both IDA and ACD. The prevalence of ID was 35%. Fatigue was found in 44% of patients, and the physical dimensions of fatigue were the most marked. Anaemia and/or ID were not associated with increased fatigue. CONCLUSIONS: 1. Treatment with iron supplementations of post-discharge anaemia after AUGIB had significant effect on Hb levels. Intravenous iron supplementation should be chosen if adherence to treatment is essential. The patients' HRQoL was not affected by anaemia. 2. Anaemia in IBD outpatients was present in one of five patients and only 20% had pure IDA. The remains had pure "ACD" or a combination between ACD and IDA. Fatigue was present in nearly half of the patients and was not associated with anaemia, but was related to gender and age. Physical fatigue was the most affected dimension of fatigue.

[A woman with long-lasting diarrhoea and fatigue]. / En ung kvinne med langvarig diaré og slapphet.

BACKGROUND: Intestinal trematodes are common parasites in man and many mammals. Infection is often asymptomatic and unrecognised. CASE PRESENTATION: A woman in her twenties presented with loose stools of variable intensity over six months. Additionally, she had experienced considerable fatigue during this period. There was no weight loss and initial blood tests were normal. Further testing at the second visit included stool microscopy, and small trematode eggs consistent with H. heterophyes infection were found. A more thorough anamnesis revealed the onset of symptoms on the day she returned from a week's holiday, and the probable exposure occurred from eating sushi twice during this holiday. After one day of treatment with praziquantel 40 mg/kg administered in three doses, the patient recovered completely within two to four weeks. Her asymptomatic partner had consumed the same food and had the same eggs in his stool sample. He was successfully treated with the same treatment dose. INTERPRETATION: A detailed travel history may provide important information relating to the diagnosis of diarrhoea and fatigue. Symptoms of H. heterophyes infection are variable. A single day's dose of 40 mg/kg of praziquantel was sufficient to eradicate infection in the two cases presented.

Neuropsychiatric symptoms are common in immunocompetent adult patients with Toxoplasma gondii acute lymphadenitis.

BACKGROUND: Chronic toxoplasmosis has been shown to be strongly associated with a range of neuropsychiatric effects including schizophrenia and suicide. However there have not been any prospective, community-based studies of the neuropsychiatric effects of acute toxoplasmosis in adult immunocompetent patients. METHODS: Adult patients with a positive serum IgM anti-Toxoplasma gondii test result, in the context of an acute illness with lymphadenopathy, were invited to complete a questionnaire seeking information relating to the nature, severity, and duration of symptoms in the months following the diagnosis of acute toxoplasmosis. RESULTS: Laboratory testing identified a total of 187 adults who had a positive serum IgM anti-T. gondii test result between 1 January and 30 November 2011. Consent to contact 108/187 (58%) patients was provided by their family doctor; 37 (34%) of these 108 patients completed and returned the questionnaire. Questionnaires from the 31/108 (29%) patients who reported swollen lymph nodes during their illness were included in the study. Fatigue (90%), headache (74%), difficulty concentrating (52%), and muscle aches (52%) were the most commonly reported symptoms. These symptoms commonly persisted for at least 4 weeks. Twenty-seven of 31 (87%) subjects reported a moderate or severe reduction in their overall physical and mental health during the first 2 months of illness. CONCLUSIONS: Acute toxoplasmosis in immunocompetent adults commonly causes moderately severe neuropsychiatric symptoms that might result from replication of the organism in the central nervous system with consequent effects on brain function. Patients should be advised that such symptoms are common and reassured that they usually resolve completely within a few months.

Severity of Giardia infection associated with post-infectious fatigue and abdominal symptoms two years after.

BACKGROUND: A high rate of post-infectious fatigue and abdominal symptoms two years after a waterborne outbreak of giardiasis in Bergen, Norway in 2004 has previously been reported. The aim of this report was to identify risk factors associated with such manifestations. METHODS: All laboratory confirmed cases of giardiasis (n = 1262) during the outbreak in Bergen in 2004 received a postal questionnaire two years after. Degree of post-infectious abdominal symptoms and fatigue, as well as previous abdominal problems, was recorded. In the statistical analyses number of treatment courses, treatment refractory infection, delayed education and sick leave were used as indices of protracted and severe Giardia infection. Age, gender, previous abdominal problems and symptoms during infection were also analysed as possible risk factors. Simple and multiple ordinal logistic regression models were used for the analyses. RESULTS: The response rate was 81% (1017/1262), 64% were women and median age was 31 years (range 3-93), compared to 61% women and 30 years (range 2-93) among all 1262 cases. Factors in multiple regression analysis significantly associated with abdominal symptoms two years after infection were: More than one treatment course, treatment refractory infection, delayed education, bloating and female gender. Abdominal problems prior to Giardia infection were not associated with post-infectious abdominal symptoms. More than one treatment course, delayed education, sick leave more than 2 weeks, and malaise at the time of infection, were significantly associated with fatigue in the multiple regression analysis, as were increasing age and previous abdominal problems. CONCLUSION: Protracted and severe giardiasis seemed to be a risk factor for post-infectious fatigue and abdominal symptoms two years after clearing the Giardia infection.

High rate of fatigue and abdominal symptoms 2 years after an outbreak of giardiasis.

The aim of this study was to evaluate the prevalence of fatigue and abdominal symptoms 2 years after Giardia lamblia infection. All 1262 cases who had Giardia-positive stool samples during an outbreak in 2004 in Norway received a questionnaire in 2006 asking about fatigue and abdominal symptoms. Fatigue was reported by 41%, whereas 38% reported abdominal symptoms, and there was a highly significant association between these symptoms. Increasing age was a highly significant risk factor for fatigue. The symptoms were not due to chronic infection in this cohort. Our data warrant further investigations into the late effects of giardiasis.

A randomized clinical trial of a psychoeducational intervention to improve outcomes in systemic lupus erythematosus.

OBJECTIVE: In a cross-sectional study, we previously identified 2 potentially modifiable risk factors for adverse outcomes in systemic lupus erythematosus (SLE): self-efficacy and social support. The goal of this study was to evaluate in a randomized controlled trial a theory-based intervention to improve patient self-efficacy and partner support to manage SLE. METHODS: Patients with SLE ages 18 years and older who met the American College of Rheumatology criteria and were able to identify a partner (spouse or family member) were recruited from 2 academic medical centers and randomized into an experimental group or a control group. Patients in the experimental group and their partners received an intervention designed to enhance self-efficacy, couples communication about lupus, social support, and problem solving, in the form of a 1-hour session with a nurse educator followed by monthly telephone counseling for 6 months. Patients in the control group and their partners received an attention placebo, including a 45-minute video presentation about lupus, and monthly telephone calls. Measures of physical and mental health status, disease activity, and psychosocial factors were collected at baseline, 6 months, and 12 months. The effect of the intervention on physical and mental health and disease activity at 6 and at 12 months was modeled with linear regression and adjusted for baseline health status, disease activity, sociodemographic factors, treatment change, and psychosocial factors. RESULTS: One hundred twenty-two patients (plus their partners) were enrolled and randomized as follows: 64 to the experimental intervention and 58 to the attention control group. The participants were predominantly white, approximately half were college educated, and the groups were balanced for sociodemographic factors. At 6 months, significantly higher scores for couples communication (P = 0.01) and problem-focused coping (P = 0.03) were seen in the experimental group compared with the control group. At 12 months (6 months after the intervention ended), social support was higher (4.4 versus 4.1; P = 0.03), self-efficacy was higher (7.2 versus 6.2; P = 0.02), couples communication was higher (3.5 versus 3.1; P = 0.03), and fatigue was lower (5.1 versus 6.3; P = 0.02) in the experimental group compared with the control group. Global mental health status at 12 months, as measured by the Short Form 36 survey, was 69 points in the experimental group compared with 58 points in the control group (P = 0.04). In multivariate models, adjusting for baseline covariates, scores for couple communication (P = 0.01) were significantly higher at 6 months, and scores for self-efficacy (P = 0.004) and global mental health status (P = 0.03) were significantly higher at 12 months in the experimental group compared with the control group, and the mean score for global physical function was higher by 7 points, which was a clinically meaningful change (P = 0.2). The mean score for fatigue was also significantly lower in the experimental group than in the control group (P = 0.05). SLE disease activity was unchanged by this intervention. CONCLUSION: This randomized, controlled trial of a theory-based educational intervention in SLE demonstrated significantly higher scores for couple communication, self-efficacy, and mental health status, and lower fatigue scores in the experimental group compared with the control group. Because couple communication and self-efficacy appear to be modifiable risk factors, they may also be potential targets in more disadvantaged populations.

[Anemia, eosinophilia and generalized weakness in a 20-year old African]. / Anämie, Eosinophilie und allgemeine Schwäche bei einem 20-jährigen Afrikaner.

CASE HISTORY AND DIAGNOSIS: A 20-year-old African man was admitted to hospital with anemia, eosinophilia, raised liver enzymes and hepatosplenomegaly. Previously, on arrival in Germany, he had undergone a routine medical check-up where simple microscopy of a feces sample as well as serology for lues, AIDS and hepatitis B had all been negative. In our hospital a stool specimen was examined for ova and parasites and revealed ova of Schistosoma mansoni and confirmed the diagnosis of bilharziosis. For the detection of helmintic ova repeated stool examinations with use of concentration techniques are required. Staging by endoscopies, ultrasonography revealed colon pseudopolyposis and periportal fibrosis complicated by portal hypertension and esophageal varices. TREATMENT AND COURSE: Chemotherapy with Praziquantel was effective in eliminating the parasites but in advanced stages chronic fibrotic changes are usually irreversible. Further monitoring will therefore be necessary in our patient. CONCLUSION: Due to increasing migration and international travel, also doctors working in industrialized countries should be aware of tropical diseases.

[Liver abscess]. / Abcès du foie.

Liver abscesses are bacterial or parasitic. In a patient presenting with fever, fatigue and upper right abdominal pain, abdominal ultrasound must be performed to reveal a liver mass. Clinical history and serologies allow presumptive diagnosis. Pyogenic abscesses are mostly secondary to biliary tree infection. Pus aspiration and culture confirm the diagnosis. Gram-negative bacilli and anaerobes are the most frequent germs. Percutaneous drainage combined with antibiotics is the standard treatment. Earlier diagnosis, better techniques for bacterial culture and adapted treatment have improved prognosis. Amoebic abscesses are less frequent but their incidence is increasing in the presence of immunosuppressed state. The diagnosis is based on abdominal ultrasound and serology. Treatment is principally medical.

[Excessive watery diarrhea and pronounced fatigue due to Cyclospora cayetanensis infection in an HIV infected traveler returning from the tropics]. / Exzessive wässrige Diarrhoe und Leistungsminderung durch eine Cyclospora-cayetanensis-Infektion bei einem HIV-infizierten Tropenaufenthalter.

We report the case of a 46-year-old HIV-1 infected patient who acquired a Cyclopsora cayetanensis infection during travel to southeast Asia. He developed excessive watery diarrhoea and pronounced fatigue, which resolved after treatment with cotrimoxazole. The term Cyclospora cayetanensis was first suggested in 1993 for the infectious agent of diarrhoea in tropical and subtropical regions. The infection is usually self-limiting. However, in HIV-1 infected persons the symptoms are often more severe and protracted. Microbiological diagnosis is performed by light microscopy and at X400 magnification of faeces fixed in SAF medium or 10% formalin preservatives.

A foodborne outbreak of Cyclospora cayetanensis at a wedding: clinical features and risk factors for illness.

BACKGROUND: Cyclospora cayetanensis, a coccidian parasite, has increasingly been recognized as a cause of gastrointestinal tract illness. We describe an outbreak of Cyclospora infection following a wedding reception. OBJECTIVES: To investigate and characterize risk factors associated with the outbreak of Cyclospora and to describe the observed clinical course and spectrum of illness. METHODS: Retrospective cohort study involving 94 of the 101 guests who attended a wedding reception at a restaurant in Boston, Mass. RESULTS: Fifty-seven respondents met the case definition of infection; 12 of these had laboratory-confirmed Cyclospora. The epidemic curve was consistent with a point source outbreak with a median incubation period of 7 days. Commonly reported symptoms included diarrhea (100%), weight loss (93%), fatigue (91%), and anorexia (90%). The illness had a characteristic waxing and waning course, with 51 persons (89%) reporting recurring symptoms and 35 (61%) reporting illness lasting more than 3 weeks. By univariate analysis, infection was significantly associated (P<.05) with consumption of wine and a dessert containing raspberries, strawberries, blackberries, and blueberries. Only the dessert remained significant by stratified analysis with an adjusted relative risk of 2.1 (95% confidence interval, 1.4-3.2). CONCLUSIONS: Findings from this study support a point source outbreak of the newly identified pathogen C cayetanensis, with berries as the vehicle of transmission. It suggests that Cyclospora may cause severe diarrhea associated with profound anorexia and weight loss, and should be considered in the evaluation of prolonged gastrointestinal tract illness.

Trichinella pseudospiralis in humans: description of a case and its treatment.

The first known human case of Trichinella pseudospiralis myositis is described. A 33 years old woman reported 5 years of relatively mild symptoms of tiredness, muscle fatigue and muscle pain after exercise. She had minimal proximal weakness. Creatinine kinase was significantly elevated, and muscle biopsy showed polymyositis and Trichinella larvae. Steroid treatment dramatically worsened the weakness. Treatment with albendazole led to complete resolution of symptoms and laboratory abnormalities. Diagnosis and identification of the parasite were based on the distinctive appearance of the unencapsulated larvae and their movement in fresh muscle, plus clinical and laboratory findings.
