TB disease patterns by HIV and diabetes status.

BACKGROUND: TB is commonly categorised as pulmonary (PTB) or extrapulmonary TB (EPTB). Knowledge of TB disease patterns (PTB and/or EPTB) and determining risk factors remains limited.METHODS: This was a prospective cohort study using point-of-care ultrasound (POCUS) in Indian patients with presumed TB. Clinical and imaging data were used to develop refined case definitions for PTB, concurrent PTB and EPTB (PTB + EPTB) and EPTB without PTB (EPTB). These groups were analysed by HIV (HIV+/-) and diabetes mellitus (DM+/-) status.RESULTS: Of 172 HIV-/DM- patients with TB, 48% had PTB, 23% PTB + EPTB and 29% had EPTB, totalling 52% with any EPTB (PTB + EPTB or EPTB). In HIV+/DM- patients with TB (n = 35), 6% had PTB, 40% had PTB + EPTB and 54% had EPTB, accounting for 94% with EPTB. In HIV-/DM+ patients with TB (n = 61), 61% had PTB, 28% had PTB + EPTB and 11% had EPTB, representing 39% with EPTB.CONCLUSION: Refined case definitions revealed high proportions of EPTB even without HIV or DM. HIV further altered the TB disease pattern towards EPTB and DM towards PTB. Therefore, the dichotomy between PTB or EPTB does not represent the actual spectrum of TB disease. EPTB should receive higher priority in research and clinical practice.

Inflammatory bowel disease in Hermansky-Pudlak syndrome: a retrospective single-centre cohort study.

BACKGROUND: Knowledge about inflammatory bowel disease (IBD) in patients with Hermansky-Pudlak syndrome (HPS), a rare autosomal recessive disorder characterized by defective biogenesis of lysosome-related organelles, could provide insights into IBD in general. OBJECTIVE: To expand the understanding of IBD in patients with HPS. METHODS: Retrospective review of records from patients with HPS evaluated at the National Institutes of Health Clinical Center from 1995 to 2019 was conducted. Clinical features of IBD, genotyping results and histologic findings of colectomy specimens were analysed. RESULTS: IBD affected 37 (14.2%; 12 male, 25 female) of 261 patients with HPS. Median age of onset was 17 years; range was 1 to 52 years. The most common symptoms of HPS IBD were hematochezia, abdominal pain and loose stools. Fistulae or extra-intestinal manifestations developed in 30% or 22%, respectively. Genotyping showed that patients with biallelic variants in HPS1, HPS3, HPS4 or HPS6 were diagnosed with IBD. Six children had very early-onset IBD. Patients with HPS-3 had mild manifestations of IBD. Medical therapy and bowel resection were utilized to treat 73% and 35% of patients with HPS IBD, respectively; 7 of 13 patients receiving anti-tumor necrosis factor alpha therapy had prolonged clinical responses. Active cryptitis, chronic inflammatory changes, granulomas and ceroid lipofuscinosis were histopathologic findings in three colectomy specimens. CONCLUSIONS: IBD resembling Crohn's disease affects some patients with HPS; genetic heterogeneity is a feature of HPS IBD. HPS3 is a new gene associated with human IBD. Very early-onset IBD can develop in HPS.

Focused Assessment with Sonography for Urinary Schistosomiasis (FASUS)-pilot evaluation of a simple point-of-care ultrasound protocol and short training program for detecting urinary tract morbidity in highly endemic settings.

BACKGROUND: Urogenital schistosomiasis (UGS) causes inflammation and fibrosis of the urinary tract. In resource-limited settings, affordable tools for morbidity assessment in clinical care are needed. Point-of-care ultrasound has not yet been validated for UGS-related pathology. METHODS: We developed a protocol for Focused Assessment with Sonography for Urinary Schistosomiasis (FASUS), assessing pathology of the bladder wall, ureters and kidneys. Following standardized training, two clinicians performed FASUS on children and adults with hematuria in Lambaréné, Gabon. Recorded ultrasound clips were remotely reviewed by two ultrasound experts as a diagnostic reference. RESULTS: In 2015 and 2016, scans were performed in 118 patients. The image quality was sufficient in 90% of bladder views and more than 97% of kidney views. UGS-compatible pathology was detected in 51/118 (43%) by the operator and in 46/107 (43%) by the experts among baseline scans of sufficient quality. Inter-rater agreement between operators and experts was very good (κ > 0.8) for hydronephrosis and good (κ > 0.6) for bladder wall thickening. CONCLUSIONS: FASUS is a promising clinical, point-of-care tool for detecting UGS-related urinary tract morbidity in symptomatic patients. Based on larger validation studies, appropriate diagnostic and therapeutic algorithms for the use of FASUS should be established.

Successful establishment of third-line antiretroviral therapy in Malawi: lessons learned.

SETTING: Malawi has an extensive national antiretroviral treatment (ART) program, and although less than 2% of all patients receive second-line ART, there are increasingly more patients failing on these regimens. OBJECTIVE: To establish a virtual ART committee using limited available local facilities and expertise to recommend third-line regimens based on genotype resistance of samples sent abroad. DESIGN: A secretariat and a laboratory sample hub were established. The committee started work after locally organizing training courses. Decisions about ART regimens were mainly based on a relatively simple, previously described algorithm, which allowed decisions to be taken without extensive expert knowledge. RESULTS: Of the 25 applications assessed, 23 samples were sent for resistance testing from June 2017 to April 2018. Major protease inhibitor (PI) resistance was detected in 65% of the samples. PI resistance was found even in patients exposed to PIs for short periods. In particular, patients who received co-administration of PIs and rifampicin frequently showed resistance mutations. CONCLUSION: Third-line ART using genotypic resistance testing and algorithm-based treatment regimens are feasible in low-resource settings. Our model can serve as a base for similar programs initiating programmatic third-line ART in other African countries.

Assessing the effect of different operation techniques on postoperative duplex ultrasound quality after carotid endarterectomy.

BACKGROUND: Duplex ultrasound is the first choice in diagnostics and surveillance of stenoses of the internal carotid arteries before and even after surgery. Therefore, the quality of duplex ultrasound is crucial to investigate these vascular pathologies. OBJECTIVE: Aim of this study was the evaluation whether different surgical techniques affect the postoperative quality of duplex ultrasound. METHODS: In a time period from January to May 2015 duplex ultrasound of the cervical vessels was performed in 75 patients after unilateral endarterectomy of the internal carotid artery at our department between 2006 and 2012. Thereby, the non-operated contralateral side served as a control. Study groups were defined by the surgical techniques of eversion- or thrombendarterectomy with patch plasty using different patch materials and/or a haemostatic sealant. Duplex ultrasound analysis included acoustic impedance, extinction of ultrasound, thickness of skin and individual anatomic aspects of the patients. RESULTS: Carotid endarterectomy itself reduced intravascular grey levels, skin thickness and increased extinction of duplex ultrasound when compared to the non-operated side of the neck. In contrast, neither the kind of chosen operative technique nor the use of different patch materials or the application of a haemostatic sealant showed an effect in this regards. CONCLUSIONS: Whereas carotid endarterectomy per se worsens the quality of postoperative duplex ultrasound, the different analysed surgical techniques as well as used patches and the application of a haemostatic sealant can be assumed to be equal regarding the quality of postoperative ultrasound.

Reported gum disease as a cardiovascular risk factor in adults with intellectual disabilities.

BACKGROUND: Several risk factors for cardiovascular disease (CVD) have been identified among adults with intellectual disabilities (ID). Periodontitis has been reported to increase the risk of developing a CVD in the general population. Given that individuals with ID have been reported to have a higher prevalence of poor oral health than the general population, the purpose of this study was to determine whether adults with ID with informant reported gum disease present greater reported CVD than those who do not have reported gum disease and whether gum disease can be considered a risk factor for CVD. METHODS: Using baseline data from the Longitudinal Health and Intellectual Disability Study from which informant survey data were collected, 128 participants with reported gum disease and 1252 subjects without reported gum disease were identified. A series of univariate logistic regressions was conducted to identify potential confounding factors for a multiple logistic regression. RESULTS: The series of univariate logistic regressions identified age, Down syndrome, hypercholesterolemia, hypertension, reported gum disease, daily consumption of fruits and vegetables and the addition of table salt as significant risk factors for reported CVD. When the significant factors from the univariate logistic regression were included in the multiple logistic analysis, reported gum disease remained as an independent risk factor for reported CVD after adjusting for the remaining risk factors. Compared with the adults with ID without reported gum disease, adults in the gum disease group demonstrated a significantly higher prevalence of reported CVD (19.5% vs. 9.7%; P = .001). CONCLUSION: After controlling for other risk factors, reported gum disease among adults with ID may be associated with a higher risk of CVD. However, further research that also includes clinical indices of periodontal disease and CVD for this population is needed to determine if there is a causal relationship between gum disease and CVD.

Complications of percutaneous liver biopsy with Klatskin needles: a 36-year single-centre experience.

BACKGROUND: Liver biopsy is the gold standard in evaluating liver diseases but is susceptible to complications. Safety data on aspiration needle biopsies remain limited. AIM: To evaluate the safety of percutaneous liver biopsy performed with Klatskin needle. METHODS: Clinical and biochemical data were retrospectively retrieved from sequential subjects who underwent liver biopsy with Klatskin needle from 1978 to 2015. Subjects with complications underwent thorough chart reviews for hospital course. RESULTS: Of 3357 biopsies performed, complications occurred in 135 (4%) biopsies with 33 (1%) resulting in major complications. Severe pain occurred in 78 (2.3%) subjects and bleeding occurred in 21 (0.6%) subjects. Biliary injury occurred in 8 (0.2%) biopsies. Three subjects died as a result of massive intraperitoneal bleeding. Compared to viral hepatitis, biopsies performed with certain diagnosis had significantly higher odds of major complications: NRH (OR: 17), DILI (OR: 20), GVHD (OR: 32) and HCC (OR: 34). Subjects with major complications had higher pre-biopsy median AP (153 vs. 78 U/L, P < 0.001), ALT (105 vs. 64 U/L, P < 0.05), AST (62 vs. 47 U/L, P < 0.02), along with marginally lower total bilirubin (1.0 vs. 0.7 mg/dL, P < 0.01) and albumin (3.7 vs. 4.0 g/dL, P < 0.001). By multivariate backward logistic regression, platelets ≤100 K/µL and aPTT >35 were independent risk factors of post-biopsy bleeding. CONCLUSION: Klatskin needle liver biopsies are safe with rare procedural morbidity. Our data suggests certain acutely ill subjects and those with systemic illnesses may be at higher risk of major complications. Clinicians should weigh the risks and benefits of liver biopsy in these patients with other alternative approaches.

Changes in Quality of Diabetes Care and Morbidity over 20 Years in People with Type 1 Diabetes and Long Diabetes Duration: The JEVIN Trial.

Background: The JEVIN trial started as a cross-sectional study in 1989/90 in Jena, a city of the former German Democratic Republic. At that time, the centralized diabetes care system was broken down and restarted 10 years later; structured treatment and teaching programs were implemented, blood glucose self-monitoring, insulin pump-systems and analogue insulin were introduced. We surveyed people with type-1-diabetes of the baseline JEVIN trial in a 20-year follow-up. Methods: 131 patients with type-1-diabetes were analyzed in 1989/90. Of the living population in 2009/10 (n=104), 83 persons were identified and 75 persons with a mean diabetes duration of 35 years were reexamined regarding HbA1c, self-monitoring, diabetes therapy, severe hypoglycemia, diabetic late complications and compared with the results of the same persons in 1989/90. Results: HbA1c decreased from 57.1 mmol/mol in 1989/90 to 52.7 mmol/mol in 2009/10 (7.4 -7.0%; p=0.049). Self-monitoring of blood glucose increased from 2 to 35 tests/week (p<0.001). 100%-use of animal insulin changed to human and analogue insulin therapy. The incidence of severe hypoglycemia increased from 0.1 to 0.16/patient-year. Retinopathy increased from 29 to 69% (p<0.001), nephropathy from 5 to 27% (p<0.001) and neuropathy from 13 to 43% (p<0.001). 17% had no diabetic late complications. Conclusions: The JEVIN trial shows a significant improve in HbA1c in the past 20 years. Severe hypoglycemia occurred rarely and 17% were still free of any diabetic late complication after 35 years of diabetes. This indicates a good quality of diabetes care in a German setting.

Noninvasive markers for staging fibrosis in chronic delta hepatitis.

BACKGROUND: Serum fibrosis markers are useful in staging chronic hepatitis B (HBV) and C (HCV) virus but have not been evaluated in chronic hepatitis D virus (HDV). AIM: To evaluate the utility of serum fibrosis markers [fibrosis-4 score (FIB-4), aspartate aminotransferase (AST) to alanine aminotransferase (ALT) ratio, aspartate aminotransferase ratio (AAR), age-platelet index (API), AST-to-platelet-ratio-index (APRI) and Hui score] in HDV infection. METHODS: Clinical and histologic laboratory data from HBV, HCV and HDV patients were evaluated and serum fibrosis markers were calculated. The ability of fibrosis markers to detect advanced fibrosis (Ishak ≥4) and cirrhosis (Ishak = 6) were evaluated and compared between viral infections. RESULTS: A total of 1003 subjects (HCV = 701, HBV = 240 and HDV = 62) with mean age of 46 ± 11 and 66% male were evaluated. HDV subjects had higher ALT and AST than HCV and lower platelets than both HBV and HCV. Histologically, HDV had the greatest percentage of Ishak ≥4 and necroinflammation. FIB-4 performed best in detecting advanced fibrosis and cirrhosis in all viral cohorts. In HDV, area under the receiver operator curve (AUROC) 95% confidence intervals for detecting advanced fibrosis were: FIB-4 = 0.70 (0.55-0.84), API = 0.69 (0.55-0.82), APRI = 0.68 (0.54-0.82), Hui score = 0.63 (0.49-0.78), AAR = 0.63 (0.48-0.77). The AUROC for detecting cirrhosis in HDV were: FIB-4 = 0.83 (0.69-0.97), API = 0.80 (0.66-0.95), APRI = 0.75 (0.61-0.89), Hui score = 0.70 (0.49-0.91) and AAR = 0.70 (0.48-0.93). Adjustment of published cut-offs led to marginal improvements in FIB4 for advanced fibrosis and of APRI for cirrhosis in HDV. CONCLUSIONS: Serum fibrosis markers have lower performance accuracy in chronic HDV infected patients compared to HBV and HCV patients. Other noninvasive fibrosis markers should be explored to assist in the management of these patients.

Individual, parent and social-environmental correlates of caregiving experiences among parents of adults with autism spectrum disorder.

INTRODUCTION: Compared to parents of adults with other types of disabilities, parents of adults with autism spectrum disorder (ASD) experience worse well-being. Thus, it is crucial to identify the individual, parent and social-environmental correlates of caregiving experiences among parents of adults with ASD. METHOD: For this study, 130 parents of adults with ASD responded to a survey about caregiving satisfaction, self-efficacy and burden. RESULTS: Greater future planning and community involvement related to more caregiving satisfaction and increased caregiving self-efficacy, respectively. Less choicemaking of the adult with ASD related to greater caregiving satisfaction and self-efficacy. Maladaptive behaviours and poor health of the adult with ASD related to greater caregiving burden. CONCLUSIONS: Implications for policymakers, practitioners and future research are discussed.

Miliary tuberculosis: sonographic pattern in chest ultrasound.

Miliary tuberculosis (TB) is characterized by a multitude of small nodular opacities on chest radiography. Despite ultrasound of the chest gaining wider acceptance as a diagnostic tool of lung infections, sonographic changes of pulmonary miliary TB have not yet been reported. Here, we describe B-lines and comet-tail artifacts disseminated throughout multiple lung areas and a pattern of sub-pleural granularity as consistent changes seen in lung ultrasound of ten patients with pulmonary miliary TB diagnosed by chest radiography.

Liver injury is associated with mortality in sickle cell disease.

BACKGROUND: Increased life expectancy in sickle cell disease (SCD) has resulted in greater recognition of the consequences of repeated intravascular vaso-occlusion and chronic haemolysis to multiple organ systems. AIM: To report the long-term consequences of liver dysfunction in SCD. METHODS: A cohort of SCD patients was prospectively evaluated at the National Institutes of Health (NIH) Clinical Center. The association of mortality with liver enzymes, parameters of liver synthetic function and iron overload was evaluated using Cox regression. RESULTS: Exactly, 247 SCD patients were followed up for 30 months of whom 22 (9%) died. After controlling for predictors, increased direct bilirubin (DB), ferritin, alkaline phosphatase and decreased albumin were independently associated with mortality. In a multivariable model, only high DB and ferritin remained significant. Ferritin correlated with hepatic iron content and total blood transfusions but not haemolysis markers. Forty patients underwent liver biopsies and 11 (28%) had fibrosis. Twelve of 26 patients (48%) had portal hypertension by hepatic venous pressure gradient (HVPG) measurements. All patients with advanced liver fibrosis had iron overload; however, most patients (69%) with iron overload were without significant hepatic fibrosis. Ferritin did not correlate with left ventricular dysfunction by echocardiography. DB correlated with bile acid levels suggesting liver pathology. Platelet count and soluble CD14 correlated with HVPG indicating portal hypertension. CONCLUSIONS: Ferritin and direct bilirubin are independently associated with mortality in sickle cell disease. Ferritin likely relates to transfusional iron overload, while direct bilirubin suggests impairment of hepatic function, possibly impairing patients' ability to tolerate systemic insults.

Healthcare utilization of people with type 2 diabetes in Germany: an analysis based on health insurance data.

AIMS: This population-based study assesses the healthcare utilization of people with Type 2 diabetes by analysing routine data from Allgemeine Orts-Krankenkasse (AOK), the largest statutory health insurance provider in Germany. METHODS: Anonymized billing data from all AOK-insured persons with at least one day of insurance during the evaluation year 2010 were analysed. Treatment and cost data from all areas of inpatient and outpatient care were available, as was information regarding patient age and sex. International Classification of Diseases (ICD-10) diagnosis and Anatomical Therapeutic Chemical (ATC) classification were used to identify 2.7 million insured persons with diabetes. RESULTS: The age- and sex-standardized prevalence of Type 2 diabetes was 9.8%. Of those patients identified, 33.9% had at least one diabetes-related complication and 83.0% had a diagnosis of hypertension. Almost two-thirds (63.1%) received antihyperglycaemic medication. Metformin and sulfonylurea were prescribed most often; medications without proof of benefit in endpoint studies were prescribed much less frequently. People without diabetes were admitted to hospital only half as often as those with Type 2 diabetes. The projected total expenditure in Germany for all people with Type 2 diabetes amounted to approximately €33.3 billion in 2010. CONCLUSIONS: This study shows an increase in both the prevalence of diabetes and treatment costs. The majority of people with Type 2 diabetes were aged 70 years or older. One third of this group has diabetes-related complications. Antihyperglycaemic medications without proof of benefit in endpoint studies were prescribed much less frequently than drugs with proof of benefit.

Use of snacks in insulin-treated people with diabetes mellitus and association with HbA1c , weight and quality of life: a cross sectional study.

AIM: Insulin therapies with prandial injections offer the possibility to skip snacks or omit meals. It is unclear how many people with insulin-treated diabetes mellitus eat snacks and whether they snack for their own comfort or only on the recommendation of healthcare professionals. METHODS: In 2004, 163 consecutive people with insulin-treated diabetes seen in a university outpatient department were interviewed regarding their diet and degree of satisfaction with their meals. Fifty-five had Type 1 diabetes [age 47 years; diabetes duration 18 years; BMI 27 kg/m(2) ; HbA1c 62 mmol/mol (7.8%)], 53 had Type 2 diabetes with biphasic insulin therapy [age 68 years; diabetes duration 17 years; BMI 31 kg/m(2) ; HbA1c 60 mmol/mol (7.6%)] and 55 had Type 2 diabetes with prandial insulin therapy [age 60 years; diabetes duration 16 years; BMI 33 kg/m(2) ; HbA1c 59 mmol/mol (7.6%)]. RESULTS: Eighty per cent of those with Type 1 diabetes ate snacks, together with 77% of the Type 2 diabetes/biphasic group and 62% of the Type 2 diabetes/prandial group. Most participants (91% Type 1 diabetes, 88% Type 2 diabetes/biphasic group, 82% Type 2 diabetes/prandial group) liked to have snacks. The time at which they ate snacks was the same for both diabetes types. There were no differences between participants with Type 1 diabetes who snacked and those who did not in terms of age (P = 0.350), BMI (P = 0.368), HbA1c (P = 0.257) and time since diagnosis (P = 0.846). Participants with Type 2 diabetes who ate snacks were older than those who did not (biphasic: P = 0.006; prandial: P = 0.008). There were no differences in terms of BMI (biphasic: P = 0.731; prandial: P = 0.393), HbA1c (biphasic: P = 0.747; prandial: P = 0.616) and time since diagnosis (biphasic: P = 0.06; prandial: P = 0.620). CONCLUSIONS: Most people with insulin-treated diabetes eat snacks voluntarily and not because of physicians' instructions. There were no correlations between the use of snacks and HbA1c , BMI and time since diagnosis, except that the participants with Type 2 diabetes who ate snacks were older.

Changes of FASH ultrasound findings in TB-HIV patients during anti-tuberculosis treatment.

Ultrasound findings of extra-pulmonary tuberculosis (TB) have been well-described, particularly in human immunodeficiency virus (HIV) co-infected patients, and are often used as a basis of diagnosis in high-prevalence settings. Changes in findings during anti-tuberculosis treatment are less well documented. We present a single-centre case series of 21 TB-HIV co-infected individuals with typical ultrasound findings present at baseline. In 16/21 (76%) patients, all findings had resolved by month 3 of treatment. In patients with persistent ultrasound findings at 3 months, non-adherence, drug resistance, chronic disease, immune-reconstitution inflammatory syndrome and alternative diagnoses were identified. Follow-up ultrasound at month 3 may help identify high-risk cases.
