Active tuberculosis in patients undergoing hemodialysis for end-stage renal disease: a 9-year retrospective analysis in a single center

Risk factors of latent tuberculosis among chronic kidney disease with routine haemodialysis patients

•

Since tuberculosis still become an important health problem in the world, especially in developing countries, CKD patients also become a high-risk population to TBC infection.

•

Due to immunity impairment in CKD patients, particularly who are routinely hemodialyzed, tuberculosis is not always clinically manifested (latent).

•

However, tuberculosis among CKD patients contribute to greater morbidity, quality of life and morbidity. Hence, we investigated the factors that associated with latent tuberculosis among CKD on haemodialysis patients.

•

By understanding it, management of CKD patients could be more comprehensive, and the morbidity and mortality could be decreased while quality of life could be increased.

•

We also provide the first documentation study of tuberculosis among CKD on haemodialysis patients in Indonesia, one of the tuberculosis endemic country.

•

According our study, smoking status and HD adequacy based on URR < 73% are associated factors that contribute to LTB among CKD on HD patients.

Hemodialysis in the Compact Nations of the US Affiliated Pacific: History and Health Care Implications

Background: The epidemic of non-communicable disease in the Compact nations of the US Affiliated Pacific Islands and the associated renal complications drive the demand for hemodialysis. Limited healthcare budgets and a lack of trained human health resources in these areas make hemodialysis a challenging undertaking that may require significant sacrifices in competing health care priorities. Methods: Two nephrologists who developed hemodialysis in the US Affiliated Pacific Islands provide its history. Cost estimates of hemodialysis for the Compact nations are collected from a 2014 hemodialysis feasibility report. The experiences and outcomes of current hemodialysis centers in the United States and other island nations provide a framework by which to assess the potential benefit and impact of hemodialysis in the Compact nations. Discussion: A consideration of how and why different stakeholders value hemodialysis will be crucial because they will drive the public's response to the institutionalization of any new intervention or the cessation of any existing intervention like hemodialysis. Conclusion: Updated cost estimates for dialysis clinics and data on renal disease rates in the Compact nations will be necessary to make informed decisions about hemodialysis in the current health systems. In the meantime, it is essential to enhance current medical interventions and public health strategies to prevent kidney disease and decrease the risks for kidney failure. Such preventive interventions must be culturally appropriate, effective, cost-efficient, and sustainable in the unique context of the Pacific.

Impact of renal function-based anti-tuberculosis drug dosage adjustment on efficacy and safety outcomes in pulmonary tuberculosis complicated with chronic kidney disease

Background

Dosages of anti-tuberculosis (TB) drugs are recommended to be adjusted according to renal function for patients complicated with chronic kidney disease (CKD). However, the efficacy and safety outcomes of such renal function-based dosage adjustments are not fully elucidated.

Methods

We retrospectively reviewed cases of pulmonary TB susceptible to first-line drugs that were treated at Jikei University Daisan Hospital between 2005 and 2014 with standard regimens based on dosage adjustments according to renal function recommended by international guidelines. Patients were divided into four groups, those with no, mild, moderate or severe CKD. In-hospital TB-related mortality, the rate of sputum culture conversion at 2 months, the frequency of adverse events (AEs), for which at least the temporal discontinuation of the suspect drug was required for patient improvement, and the rate of regimen change due to AEs were assessed.

Results

In the 241 enrolled patients (mean age, 64.1 years; 143 men), fourteen patients (5.8%) died due to TB during their hospitalization. The rate of sputum culture conversion at 2 months was 78.0%. The frequency of in-hospital TB-related death and the conversion rate in the groups did not vary significantly according to CKD severity including those in the non-CKD group (P = 0.310 and P = 0.864). Meanwhile, a total of 70 AEs were observed in 60 patients (24.9%) and the difference between the groups in the overall frequency of AEs was almost significant (P = 0.051). Moreover, for the 154 patients with CKD, severe CKD stage was a significant risk factor for regimen change (OR = 5.92, 95% CI = 1.08–32.5, P = 0.041), as were drug-induced hepatitis and cutaneous reaction (OR = 35.6, 95% CI = 8.70–145, P < 0.001; OR = 17.4, 95% CI = 3.16–95.5, P = 0.001; respectively).

Conclusions

Adjusting the dosage of TB treatment for CKD patients according to the guidelines was efficient in terms of similar therapeutic outcome to that of the non-CKD group. However, AEs warrant attention to avoid regimen change in patients with severe CKD, even if the renal function-based dosage adjustment is performed.

Tuberculosis in dialysis: Clinical spectrum and outcome from an endemic region

INTRODUCTION

Tuberculosis (TB) is a significant health problem in developing countries. There are limited data on TB among end stage renal disease (ESRD) patients on maintenance dialysis in India. Clinical profile and outcome of TB in dialysis were studied.

METHODS

Retrospective study of ESRD patients who were on maintenance dialysis (either peritoneal dialysis [PD] or hemodialysis (HD]) and diagnosed to have TB over a period of 11 years.

FINDINGS

Thirty-two patients had a diagnosis of TB. Mean age of the patients was 50.3 ±13.9 years. The majority (56.2%) of the patients were female. The modality of dialysis was HD in 53.1% and PD in 46.9%. Mean duration of dialysis at the diagnosis of TB was 15.1 ± 13.9 months. Over three-quarter of the patients had an extrapulmonary involvement. Pleuro-pulmonary (40.6%), peritoneum (34.4%), and lymph node (15.6%) were the most common sites for TB. About 6.3%patients had disseminated TB, and 3.1% had pericardial TB. The clinical presentation of TB was: fever/pyrexia of unknown origin 28.1%, constitutional symptoms of anorexia, fever, night sweats and weight loss 34.4%, abnormal chest radiograph 37.5%, ascites/peritonitis 34.4%, pleural effusion 25%, lymphadenopathy 18.8%, meningoencephalitis 6.3%, and pericardial effusion 3.1%. Peritoneal TB presented as nonresolving peritonitis in PD and ascites in HD. The diagnosis was a microbiological/histological in 50% and rest 50% only on clinical grounds. Nine (29%) patients had adverse effects of anti-TB drugs. Four patients of TB peritonitis had a poor gastrointestinal tolerance of anti-TB drugs and defaulted on the treatment and had an adverse outcome. About 53.1% of the patients survived, and 46.9% died.

DISCUSSION

TB in dialysis is mostly extrapulmonary. Early diagnosis is difficult, and the adverse effects of anti-TB medications complicate the treatment. TB in dialysis carries high morbidity and mortality. TB peritonitis has a poor prognosis.

Incidence of tuberculosis is high in chronic kidney disease patients in South East England and drug resistance common

The risk of tuberculosis (TB) is significantly increased in chronic kidney disease (CKD). Data on TB in CKD in the UK are sparse; most information stems from countries with high background prevalence. The aim of this study was to estimate the incidence of TB in CKD patients in South East London and to describe the epidemiology, treatment, and outcome. CKD patients with TB between 1994 and 2010 were identified retrospectively. Data were collected on type of renal replacement therapy, the method of TB diagnosis, disease site, treatment regimens, and risk factors. Forty patients were identified of whom 67.5% had CKD stages IV-V. Sixty-five percent were from non-UK born ethnic minorities. Median time from diagnosis of CKD to TB development was 12 months (range 0-192 months). Cumulative incidence of TB was 1267/100,000 [95% confidence interval (CI): 630-1904; 85 × background UK rate] in hemodialysis patients; 398/100,000 (95% CI: 80-1160; 26 × background UK rate) in peritoneal dialysis; and 522/100,000 (CI: 137-909; 35 × background UK rate) in transplant recipients. Sixty-three percent of patients had pulmonary TB and 25% of patients with culture-positive TB had resistant isolates. Fifty percent of patients were immunosuppressed due to drugs, diabetes, and/or retroviral disease. Treatment regimens were according to recent national guidance in 73% of cases. Seventy-six percent of patients experienced side effects. Greater awareness of risk factors, drug resistance, treatment regimens, and potential side effects is needed.

Tuberculosis in haemodialysis patients: A single centre experience

We prospectively followed-up new patients of tuberculosis while on maintenance hemodialysis at a State Government-run tertiary care institute. Between 2000 and 2010, 1237 new patients were initiated on maintainence hemodialysis. The number of patients diagnosed with tuberculosis after initiation of hemodialysis was 131 (10.5% of 1237). The age was 46.4 ± 10.4 (range 8-85) years and there were 90 (68.7%) males. The number of patients diagnosed with tuberculosis on the basis of organ involvement were: Pulmonary-60, pleural effusion-31, lymph node-21, meningitis-8, pericardial effusion-7, peritoneum-2, latent tuberculosis-2. The incidence of tuberculosis in hemodialysis was found to be 105.9 per 1000 patient years. Male gender, diabetes mellitus, past history of tuberculosis, mining as an occupation, low serum albumin, and duration of hemodialysis more than 24 months, and unemployment were found to be significant risk-factors on univariate analysis.

Extra-pulmonary tuberculosis infection in the dialysis patients with end stage renal diseases: case reports and literature review

The diagnosis of extra-pulmonary tuberculosis (TB) seems relatively difficult due to the absence of specific symptoms and signs in patients on peritoneal dialysis or hemodialysis. We report four cases of extra-pulmonary tuberculosis on dialysis, with two cases on peritoneal dialysis and two cases on hemodialysis. The presentations, therapy, and outcomes of TB infection in these patients were reviewed. Otherwise, the English literature published in the PubMed database associating extra-pulmonary tuberculosis on dialysis over the last three decades is reviewed. A total of 61 studies containing 70 cases were included. The most common primary disease was diabetic nephropathy (22.86%, 16/70). The peritoneum (31.42%, 22/70), bone (21.42%, 15/70), and lymph node (20%, 14/70) were the most frequently infected. Single organ infection was common (90%, 63/70). Fever (58.57%, 41/70), pain (35.71%, 25/70), and enlarged lymph node (20%, 14/70) were the most common symptoms. Biopsy (67.14%, 47/70) and culture (40%, 28/70) provided most reliable methods for clear diagnosis of tuberculosis. The combined treatment of isoniazid, rifampicin, pyrazinamide, and ethambutol (44.29%, 31/70) was the most common therapy. The majority of patients improved (82.86%, 58/70); however, 12 cases got worse (17.14%), with 10 of them dying (14.29%). Physicians should be aware of the non-specific symptoms and location of infection, and consider tuberculosis in their differential diagnoses in dialysis patients presenting with symptoms such as fever, pain, and weight loss.

Evidence from Chile that arsenic in drinking water may increase mortality from pulmonary tuberculosis

Arsenic in drinking water causes increased mortality from several cancers, ischemic heart disease, bronchiectasis, and other diseases. This paper presents the first evidence relating arsenic exposure to pulmonary tuberculosis, by estimating mortality rate ratios for Region II of Chile compared with Region V for the years 1958-2000. The authors compared mortality rate ratios with time patterns of arsenic exposure, which increased abruptly in 1958 in Region II and then declined starting in 1971. Tuberculosis mortality rate ratios in men started increasing in 1968, 10 years after high arsenic exposure commenced. The peak male 5-year mortality rate ratio occurred during 1982-1986 (rate ratio = 2.1, 95% confidence interval: 1.7, 2.6; P < 0.001) and subsequently declined. Mortality rates in women were also elevated but with fewer excess pulmonary tuberculosis deaths (359 among men and 95 among women). The clear rise and fall of tuberculosis mortality rate ratios in men following high arsenic exposure are consistent with a causal relation. The findings are biologically plausible in view of evidence that arsenic is an immunosuppressant and also a cause of chronic lung disease. Finding weaker associations in women is unsurprising, because this is true of most arsenic-caused health effects. Confirmatory evidence is needed from other arsenic-exposed populations.
