Evaluation of treatment regimens and long-term clinical outcomes in patients with isoniazid-resistant pulmonary tuberculosis: a 5-year follow-up.

BACKGROUND: Considering its early bactericidal activity, isoniazid (H) is an important first-line agent in tuberculosis (TB) treatment.The aim of this study was to evaluate the treatment regimens and results of H-resistant pulmonary TB patients. METHODS: We retrospectively evaluated treatment regimens and results of 188 H-resistant pulmonary TB patients who were treated in our center between January 2015 and December 2017. Treatment regimens applied were noted and treatment outcomes were recorded. The long-term results were evaluated. RESULTS: Totally 174 (92.6%) of 188 patients with H-resistant pulmonary TB achieved treatment success. Ninety-seven patients (51.6%)were cured and 77 patients (41.0%) completed treatment. Five patients (2.7%) had treatment failure. Four patients (2.1%) having treatment success relapsed during one-year follow-up. Eighteen patients (9.6%) had unfavorable outcomes, including treatment failure in five (2.7%), death in nine (4.8%), and relapse in four patients (2.1%). The treatment success rate was found to be statistically higher in group 1 (9-month regimen 2HREZ/7HRE) compared with those in group 2 (9HREZ) (97.4% vs. 85.9%; p = 0.010). Group 3 (HREZFQ) and group 1 had statistically significant favorable outcomes, compared to group 2 (group 2 vs. group 3, p = 0.048; group 1 vs. group 2, p = 0.022). Interestingly, no relapse and acquired rifampicin resistance in patients occurred who received an FQ-containing regimen. DISCUSSION: Our study results show higher treatment success and positive results with the treatment regimen containing FQ and that treatment with HREZ for nine months is associated with a lower treatment success rate.

The Adverse Effects and Treatment Results of Smoking Cessation Pharmacotherapy During Fasting/Non-Fasting State.

BACKGROUND: Cigarette smoking is one of the most common addictions worldwide. Muslim smokers reduce the number of cigarettes they smoke during Ramadan due to the long fasting hours. OBJECTIVES: We aimed to share our experience in a smoking cessation clinic during Ramadan by analyzing the efficacy and adverse effects of once-daily dosing of bupropion or varenicline in a fasting group compared with conventional dosing in a non-fasting group. METHODS: We analyzed 57 patients who attended our smoking cessation clinic during Ramadan of 2014 and 2015, and at least one follow-up visit. For the fasting patients, we prescribed bupropion or varenicline after dinner (once daily) as the maintenance therapy. We recorded demographic characteristics of the patients, fasting state, drugs taken for smoking cessation, and the dosage of the medication. At the first follow-up visit, adverse effects seen with the treatment were recorded. We conducted telephone interviews 6 months after the first visits of the patients to learn the current smoking status of the groups. RESULTS: Of the total 57 patients, 20 (35.1%) were fasting and 37 (64.9%) were not fasting. Fasting and non-fasting patients were similar for sex, age, smoking pack-years, marital status, educational status, and mean Fagerström scores (p >.05). Adverse effects and quit rates after 6 months of follow-up were similar between the fasting and non-fasting groups (p >.05). CONCLUSION: Although our sample size was small, we found no difference in the rates of adverse effects or smoking cessation using a single daily oral dose of bupropion or varenicline between a fasting group and a non-fasting group that received conventional dosing.

Does Short Message Service Increase Adherence to Smoking Cessation Clinic Appointments and Quitting Smoking?

BACKGROUND: Using innovative and scientific methods increases the rate of quitting in smokers. Short message service (SMS) is a communication tool widely used and well integrated in many people's daily lives. To increase adherence to appointments in smoking cessation clinics (SCC), it is thought that increased compliance could be achieved by falling outside the traditional methods. SMS has been shown to increase the compliance of patients with SCC appointments. AIMS: In this study, we aimed to evaluate the effect of SMS in the compliance of patients with SCC follow-up visits and smoking cessation success. STUDY DESIGN: Case-control study. METHODS: Our study was a controlled, open, prospective study. We enrolled 436 cases applied to SCC of Yedikule Training and Research Hospital between 01.10.2013-30.06.2014 and agreed to follow-up with SMS. SMS was sent to the patients to remind them of appointments at the SCC and to query their smoking state. RESULTS: Two hundred-and-eighty seven (65.8%) of the patients were male and 149 (34.2%) were female. The mean age was 45±12 years. In this study, 296 (67.9%) patients had graduated from primary school. Our patients' smoking state was queried by telephone at the 6-month follow-up and we contacted 348 patients. According to this, 88 (25.3%) patients were not smoking, and 260 (74.7%) patients were smokers. Therefore, the smoking cessation rate was 24% (n=60) in patients who did not respond to SMS reminders at all, and 28.6% (n=28) in patients answering any SMS at least once (p=0.377). Smoking cessation rate of the patients invited by SMS but who did not attend any control visits was 19.1%, and it was 34.5% in patients coming to a control visit at least once. This difference was statistically significant (p=0.001). CONCLUSION: In our study, there was increased success of smoking cessation in patients coming to control visits. We think that this may result from the possibly increased compliance to SCC appointments following reminders by SMS, and that this may also increase smoking cessation success.

Prevalence and outcomes of comorbid illnesses in elderly patients with respiratory diseases.

AIM: The aim of the present study was to determine the prevalence of comorbidities in very elderly patients hospitalized as a result of acute respiratory diseases and to analyze sex-specific differences, and to examine the effects of these comorbidities on their treatment outcomes. METHODS: A total of 3316 patients were admitted to our pulmonary inpatient clinic between 2009 and 2011, and 243 of them (aged over 80 years) with acute respiratory disease were included in our study. Data were retrospectively collected, and included demographic features, comorbidities, laboratory findings, length of hospital stay and in-hospital mortality. RESULTS: In total of 243, 144 patients (59.3%) were men and 99 patients (40.7%) were women. The mean age was 84 ± 3 years. The prevalence of comorbidity was 75.7% (n = 184). The most common comorbid disease in patients with chronic obstructive pulmonary disease was congestive heart failure (32.9%), and it was chronic obstructive pulmonary disease (49.4%) in patients with pneumonia. The rate of having one comorbidity was 58.2% (n = 107) and 35.3% (n = 65) had two. Approximately half (52.6%) of the in-hospital deaths occurred within the first 48 hours of hospitalization. The number of comorbidities was higher in the deceased patients compared with the living patients (P = 0.01). CONCLUSIONS: The present study showed that the majority of our patients had at least one comorbidity. The first 48 hours of hospitalization was very important, especially for the patients with comorbidities, to determine the need for intensive care unit and prognosis. The coexistence of comorbidities can increase the risk of mortality in the elderly. Geriatr Gerontol Int 2016; 16: 791-796.

Value of neutrophil/lymphocyte ratio in the differential diagnosis of sarcoidosis and tuberculosis.

INTRODUCTION: The differential diagnosis of sarcoidosis creates a challange due to tuberculosis also having lung and lymph node involvement. Because both diseases show granulomatous inflammation, it may not be possible to distinguish tuberculosis and sarcoidosis in pathological specimens. As a result of the complexity in the differential diagnosis of sarcoidosis and tuberculosis, new markers for differentiation are being investigated. OBJECTIVE: The aim of our study is to investigate the value of neutrophil/lymphocyte ratio (NLR) as a possible marker in differentiating sarcoidosis and tuberculosis. MATERIALS AND METHODS: In our study, 51 acid-fast bacilli (AFB) positive and/or culture-positive patients with pulmonary tuberculosis, ​​40 patients with biopsy-proven sarcoidosis and a control group consisting of 43 patients were included. In our study, information was collected retrospectively based on hospital records. RESULTS: Leukocyte and neutrophil counts, NLR, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) were significantly higher, and albumin was significantly lower in the tuberculosis group compared with sarcoidosis (for all parameters P < 0.001). The most appropriate cut-off value of NLR to distinguish tuberculosis from sarcoidosis was determined as 2.55. For this cut-off value of NLR there was 79% sensitivity, 69% specificity, 73% positive predictive value (PPV), 75% negative predictive value (NPV), and area under the curve (AUC) was 0.788. For differentiation of sarcoidosis from tuberculosis, accuracy of the NLR test according to this cut-off value was found as 76%. CONCLUSION: NLR as a little known marker in respiratory medicine was found to be supportive in differentiation of tuberculosis and sarcoidosis. More studies on this issue is needed.
