The Severity of Herpes Zoster in Inflammatory Bowel Disease Patients Treated With Anti-TNF Agents

AIM

There is a paucity of data on the clinical course and the factors affecting the clinical course of herpes zoster (HZ) in inflammatory bowel disease (IBD). Our aim was to determine the impact of anti-TNF therapy and other factors on the clinical course of HZ in IBD patients.

METHODS

We conducted a retrospective cohort study among a cohort of nation-wide Veterans Affairs patients with IBD who developed incident HZ. The exposed group consisted of eligible study patients who were actively exposed to anti-TNF alone or anti-TNF plus thiopurines at the time of HZ onset. The unexposed group consisted of patients who were only exposed to 5-ASA agents before the onset of HZ without any exposure to anti-TNF medications. The outcome of interest was the development of severe HZ that was defined by including various HZ complications.

RESULTS

A total of 295 patients were identified with an incident HZ flare during follow- up duration, and among them 69 met the definition of having a severe flare. In multivariable logistic regression analysis adjusting for sex, age at HZ flare onset, race, Charlson comorbidity score, and receipt of oral anti-HZ treatment, exposure to anti-TNF agent was not associated with an increased risk of severe HZ flare compared to exposure to mesalamine alone (adjusted relative risk (RR) 1.1, 95% confidence intervals (CI): 0.75-1.55). Among the covariates, receipt of oral anti-HZ treatment (adjusted RR 0.42, 95% CI: 0.29-0.61), advancing age at HZ onset (adjusted RR for each year increase in age 1.02, 95% CI: 1.00-1.04), and African-American race (adjusted RR with whites as reference 1.58, 95% CI: 1.02-2.44) were significantly associated with the risk of having severe HZ flare.

CONCLUSION

Our study showed that among IBD patients who developed HZ, treatment with anti-TNF agents was not associated with increased risk of developing severe HZ as compared to patients treated with 5-ASA therapy only. 10.1093/ibd/izx115_video1izx115_Video_15786486963001.

Management of Anemia in Patients with Inflammatory Bowel Disease (IBD)

PURPOSE OF REVIEW

Anemia is the most common complication as well as an extra intestinal manifestation of inflammatory bowel disease (IBD). It is associated with a significant impact on patient's quality of life (QoL); as well it represents a common cause of frequent hospitalization, delay of hospital inpatient discharge and overall increased healthcare burden. In spite of all these, anemia is still often underdiagnosed and undertreated. Our aim in this review is to provide a pathway for physicians to help them achieve early diagnosis as well as timely and appropriate treatment of anemia which in turn would hopefully reduce the prevalence and subsequent complications of this condition among IBD patients.

RECENT FINDINGS

The etiology of anemia among IBD patients is most commonly due to iron deficiency anemia (IDA) followed by anemia of chronic disease. Despite this, more than a third of anemic ulcerative colitis (UC) patients are not tested for IDA and among those tested and diagnosed with IDA, a quarter are not treated with iron replacement therapy. A new algorithm has been validated to predict who will develop moderate to severe anemia at the time of UC diagnosis. While oral iron is effective for the treatment of mild iron deficiency-related anemia, the absorption of iron is influenced by chronic inflammatory states as a consequence of the presence of elevated levels of hepcidin. Also, it is important to recognize that ferritin is elevated in chronic inflammatory states and among patients with active IBD, ferritin levels less than 100 are considered to be diagnostic of iron deficiency. Newer formulations of intra-venous (IV) iron have a good safety profile and can be used for replenishment of iron stores and prevention of iron deficiency in the future. Routine screening for anemia is important among patients with IBD. The cornerstone for the accurate management of anemia in IBD patients lies in accurately diagnosing the type of anemia. All IBD patients with IDA should be considered appropriate for therapy with iron supplementation whereas IV administration of iron is recommended in patients with clinically active IBD, or for patients who are previously intolerant to oral iron, with hemoglobin levels below 10 g/dL, and in patients who need erythropoiesis-stimulating agents (ESAs). As the recurrence of anemia is common after resolution, the monitoring for recurrent anemia is equally important during the course of therapy.

Albumin as a prognostic marker for ulcerative colitis

AIM

To evaluate the role of albumin at the time of ulcerative colitis (UC) diagnosis in predicting the clinical course of disease.

METHODS

Nationwide cohort of patients with newly diagnosed UC in the Veterans Affairs health care system was identified and divided into two categories: hypoalbuminemia (i.e., ≤ 3.5 gm/dL) or normal albumin levels (i.e., > 3.5 gm/dL) at the time of UC diagnosis. The exposure of interest was presence of hypoalbuminemia defined as albumin level ≤ 3.5 g/dL at the time of UC diagnosis. Patients were then followed over time to identify the use of ≥ 2 courses of corticosteroids (CS), thiopurines, anti-TNF medications and requirement of colectomy for UC management.

RESULTS

The eligible study cohort included 802 patients, but 92 (11.4%) patients did not have their albumin levels checked at the time of UC diagnosis, and they were excluded. A total of 710 patients, who had albumin levels checked at time of UC diagnosis, were included in our study. Amongst them, 536 patients had a normal albumin level and 174 patients had hypoalbuminemia. Patients with hypoalbuminemia at diagnosis had a higher likelihood of ≥ 2 courses of CS use (adjusted HR = 1.7, 95%CI: 1.3-2.3), higher likelihood of thiopurine or anti- TNF use (adjusted HR = 1.72, 95%CI: 1.23-2.40) than patients with normal albumin level at diagnosis. There was a trend of higher likelihood of colectomy in hypoalbuminemic patients, but it was not statistically significant (Adjusted HR = 1.7, 95%CI: 0.90-3.25).

CONCLUSION

Hypoalbuminemia at disease diagnosis can serve as a prognostic marker to predict the clinical course of UC at the time of diagnosis.

Safety of herpes zoster vaccination among inflammatory bowel disease patients being treated with anti-TNF medications

BACKGROUND

The risk of herpes zoster (HZ) is elevated in inflammatory bowel disease (IBD) patients treated with anti-TNF medications. While it is optimal to give herpes zoster vaccine prior to initiation of therapy clinical circumstances may not always allow this.

AIM

To determine the safety of giving herpes zoster vaccine while patients are on anti-TNF therapy.

METHODS

We conducted a retrospective cohort study involving IBD patients who were followed in the Veterans Affairs (VA) healthcare system between 2001 and 2016. Patients who received herpes zoster vaccine while on anti-TNF medication were identified through vaccination codes and confirmed through individual chart review. Our outcome of interest was development of HZ between 0 and 42 days after herpes zoster vaccine administration.

RESULTS

Fifty-six thousand four hundred and seventeen patients with IBD were followed in the VA healthcare system. A total of 59 individuals were on anti-TNF medication when they were given herpes zoster vaccine, and amongst them, 12 (20%) were also taking a thiopurine. Median age at the time of herpes zoster vaccine was 64.9 years and 95% of patients had a Charlson Comorbidity Index of ≥2. Median number of encounters within 42 days after receiving herpes zoster vaccine was two. No case of HZ was found within 0-42 days of HZV administration.

CONCLUSION

Our data suggest that co-administering the herpes zoster vaccine to patients who are taking anti-TNF medications is relatively safe. This study significantly expands the evidence supporting the use of herpes zoster vaccine in this population, having included an elderly group of patients with a high Charlson Comorbidity Index who are likely at a much higher risk of developing HZ.

Economic burden of epilepsy in India

PURPOSE

The economic burden due to epilepsy is not adequately examined in developing countries. Cost estimates are very important in health care planning and delivery of services. We have estimated the direct and some of the indirect costs of epilepsy in India.

METHODS

Epilepsy centers attached to University hospitals in six states of India participated in this study. Data on clinical characteristics, utilization of medical services, and costs were collected in a standardized format.

RESULTS

There were 285 patients (mean age, 22.6 + 12.5 years) drawn from six centers in this study. The annual cost of epilepsy per patient was INR 13,755 (USD, 344). The direct cost was INR 3,725 (USD, 93), and the indirect cost was INR 10,031 (USD, 251). Direct cost included medical consultations (INR 329), laboratory services (INR 271), hospitalization charges (INR 316), and cost of travel to clinics (INR 659). The indirect cost included the cost of lost productivity due to seizures, its complications, or attendance to clinics. There are approximately 5 million people with epilepsy in India. The economic burden due to epilepsy to the nation is to the tune of INR 68.75 billion (USD, 1.7 billion).

CONCLUSIONS

The annual economic burden of epilepsy in India is 88.2% of GNP per capita and 0.5% of the GNP.

Epilepsy care in six Indian cities: a multicenter study on management and service

BACKGROUND

Epilepsy care in developing countries is lagging behind than in the developed countries. Precise data on delivery of neurological services for epilepsy is essential to optimize the medical services for epilepsy care with limited resources.

OBJECTIVE

This study was carried out in order to examine the management practices and utilization of various medical services for epilepsy in different parts of India.

METHODOLOGY

University centers with epilepsy clinics, one each from six states of India, had participated in this study. Demographic data, clinical details, and data on epilepsy care were collected simultaneously on standard proforma.

RESULTS

Data on 285 patients with epilepsy (generalized epilepsy: 49.1%, localization-related epilepsy: 49.9%, others: 1%) were included. Mean age of onset of epilepsy was 14.8+11.1 years. Mean delay in diagnosis was 1.5+/-4 years. Mean distance from place of residence to the consulting neurologist was 70+/-82 km. Medical consultations before referral to epilepsy center included general practitioners (54.1%) and specialists (43.3%). Very few patients received services from clinical psychologist or social worker. Investigations included, EEG (63.2%), CT Scan (36.2%). MRI brain (8.5%) and video EEG (2.1%) were limited to a few. Nearly 75.5% were on monotherapy. Newer Anti-Epileptic Drugs (AEDs) were used only in less than 5% patients.

CONCLUSION

The services for epilepsy are urban-based and there is underutilization of services, general practitioners and specialists. Newer AEDs (although expensive) are gradually emerging in Indian market. Facilities for epilepsy surgery, therapeutic drug monitoring and services of clinical psychologist or medical social workers are limited.

Landau Kleffner syndrome

An eight-year-old male child presenting with history of generalized convulsions, gradual loss of speech and generalized EEG (electroencephalography) abnormalities was diagnosed as Landau Kleffner Syndrome. He initially developed generalized convulsions which later changed to partial seizures during the course of illness. He was started on sodium valproate and continued with the drug (30 mg/kg/day) on which, he showed improvement in speech, behavior, hyperkinesis and frequency of convulsions during the follow-up.

Weekly 1-hour infusion of paclitaxel. Clinical feasibility and efficacy in patients with hormone-refractory prostate carcinoma

BACKGROUND

Preclinically, paclitaxel given according to an intense bolus schedule has significant antitumor activity against human prostate carcinoma cell lines in SCID mice. The authors evaluated the feasibility and efficacy of weekly 1-hour infusion of paclitaxel in patients with metastatic hormone-refractory prostate carcinoma (HRPC).

METHODS

A total of 18 patients with progressive metastatic HRPC were enrolled. Patients had to have no prior chemotherapy. Paclitaxel was infused weekly at a dose of 150 mg/m(2) over 1 hour for 6 weeks every 8 weeks.

RESULTS

Eighteen patients with a median age of 68.5 years and a median prostate specific antigen (PSA) level of 82 ng/mL (range, 2.17-3196 ng/mL) were enrolled. The median number of prior hormone treatments was 2, and 12 patients on antiandrogens completed antiandrogen withdrawal. Ten of eighteen patients had bone-only metastasis and eight had metastasis to bone with lymph node and/or visceral metastasis. Seventeen patients received a total of 31 cycles (157 courses) and 1 patient refused chemotherapy. All patients were included in response evaluation. Of the 8 [corrected] patients with measurable disease, 4 achieved a major response, with 1 complete response (in the lung) and 3 partial responses (1 in the liver and 2 in the lymph nodes). Seven of eighteen patients (39%) had a PSA decline of >/=50%. The major high grade toxicity was peripheral neuropathy, with 6 patients (35%) developing Grade 3 toxicity.

CONCLUSIONS

Weekly 1-hour paclitaxel has activity in patients with HRPC. The major toxicity is peripheral neuropathy. The minimal myelosuppressive effects make a modified schedule (lower doses on the same schedule or a shorter schedule of the same dose) attractive for future combination chemotherapy trials.

Postabortal sepsis

A review of postabortal sepsis following a 2-year study undertaken at the Department of Obstetrics and Gynaecology, SSG Hospital, Baroda is presented here with a view to know the incidence of postabortal sepsis and septic induced abortions and to re-evaluate the effectiveness of the MTP services in reducing its impact on maternal morbidity and mortality, since the implementation of the MTP Act in 1972. It has been observed that postabortal sepsis is a major cause of maternal mortality even now and MCH service is to be improved to reduce the same.

Hormones in male-patients with advanced esophageal-carcinoma

Hormones are believed to play a dominant role as promoters in the growth and development of hormone-dependent cancers. Much less is known about the circulating hormones in male patients with oesophageal cancer. This lack of attention led us to evaluate the role of peptide and steroid hormones (by RIA) in male patients with oesophageal cancer (n=49). Blood samples of patients were collected pretherapeutically and data was compared with age matched controls (n=25). In this retrospective study, significantly high levels of FSH (P<0.02), LH (P<0.001) and prolactin (P<0.001) were observed with concomitant low levels of estradiol (P<0.001), DHEA-S (P<0.02) and testosterone (P<0.001) in patients when compared with respective controls. The patients when grouped according to anatomical site and histological type of the tumor, intergroup variation was not observed in these hormones. From our, study, it seems that hormonal imbalance or altered ratio of peptide and steroid hormones might be playing a significant role in the development and/or progression of oesophageal carcinoma in men.

Paraganglioma of the cauda equina

A case of paraganglioma of the cauda equina is presented. Usually reported to be benign with good prognosis, the present patient had a somewhat different course. The behaviour of the tumour was unusual, with rapid recurrence seen within first month of surgery. The need for total surgical excision and role of adjuvant radiotherapy is highlighted.
