RESUMO
The emergence of COVID-19, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), triggered a global pandemic. Concurrently, reports of mucormycosis cases surged, particularly during the second wave in India. This study aims to investigate mortality factors in COVID-19-associated mucormycosis (CAM) cases, exploring clinical, demographic, and therapeutic variables across mostly Asian and partly African countries. A retrospective, cross-sectional analysis of CAM patients from 22 medical centers across eight countries was conducted, focusing on the first 3 months post-COVID-19 diagnosis. Data collected through the ID-IRI included demographics, comorbidities, treatments, and outcomes. A total of 162 CAM patients were included. The mean age was 54.29 ± 13.04 years, with 54% male. Diabetes mellitus (85%) was prevalent, and 91% had rhino-orbital-cerebral mucormycosis. Surgical debridement was performed in 84% of the cases. Mortality was 39%, with advanced age (hazard ratio [HR] = 1.06, [P < .001]), rituximab use (HR = 21.2, P = .05), and diabetic ketoacidosis (HR = 3.58, P = .009) identified as risk factors. The mortality risk increases by approximately 5.6% for each additional year of age. Surgical debridement based on organ involvement correlated with higher survival (HR = 8.81, P < .001). The utilization of rituximab and diabetic ketoacidosis, along with advancing age, has been associated with an increased risk of mortality in CAM patients. A combination of antifungal treatment and surgical intervention has demonstrated a substantial improvement in survival outcomes.
Over a third of patients who developed mucormycosis after COVID-19 died. Older people, those on specific immunosuppressive treatments, and those with diabetic ketoacidosis had a higher risk of death. However, undergoing surgery as part of treatment significantly improved survival.

Candidemia is an important clinical condition that prolongs hospital stays and increases morbidity, mortality, and hospital costs. The aim of this retrospective study was to evaluate the epidemiological and microbiological characteristics of patients with candidemia between January 2013 and December 2019. Two hundred forty-one episodes of candidemia were observed in 230 patients, 45% of whom were female. The median age was 63 years, and 53.9% of the episodes were in the intensive care unit (ICU). Commonly observed predisposing factors for candidemia included antibiotic use (71.3%), urinary catheterization (56.3%), central venous catheter placement (50.3%), total parenteral nutrition (47.9%), solid-organ malignancy (46%), surgery (48.6%), chemotherapy (37%), and steroid treatment (25.5%). The crude mortality rate was 52.7%. A significant difference was found between survivors and non-survivors (P = 0.007) according to the Charlson Comorbidity Index. However, no statistically significant association was found between mortality and age, sex, surgical procedure, catheter-related candidemia, or Candida spp. infection. The most frequently isolated Candida sp. was C. albicans (51%). Overall resistance rates to fluconazole, voriconazole, caspofungin, micafungin, and flucytosine were 3.7%, 0%, 2.5%, 1.8%, and 1.8%, respectively. Consequently, there is a need for tests that provide higher success rates, rapid diagnosis of candidemia, and local epidemiological data on antifungal resistance.

Invasive aspergillosis is a severe infection that generally involves the lungs. Primary gastrointestinal aspergillosis is the least common form of invasive aspergillosis. A patient aged 65 years developed a febrile neutropenic episode following an autologous stem cell transplant for plasmacytoid variant diffuse large B-cell gastric non-Hodgkin's lymphoma. He had abdominal pain on the second day of the febrile neutropenic episode and ileus occurred on the sixth day. His general condition deteriorated despite broad spectrum antibiotics and caspofungin treatment, and intestinal perforation occurred on the nineteenth day of the febrile neutropenic episode. Pathological examination of the resected jejunum and ileum revealed mould hyphae compatible with aspergillus. The patient died due to massive gastrointestinal bleeding on the fifth post-operative day. Although a rare condition, primary gastrointestinal aspergillosis should be kept in mind while treating neutropenic patients with gastrointestinal symptoms.

Hemophagocytic Lymphohistiocytosis (HLH) is an indicator of an exaggerated immune response and eventually adverse outcomes. This study aimed to investigate the clinical and laboratory features and outcomes of patients with HLH. The medical records of 26 HLH adult patients (≥ 16 years of age) were retrospectively analyzed. Gender, age, the duration of fever, time to diagnosis, etiology and laboratory data were extracted from the records. The mean age was 38 ± 18 years, and 15 (58%) patients were female. A total of nine cases had infectious diseases; four cases had rheumatologic diseases, three cases had hematological malignancies while nine cases could not have a definitive diagnosis. The median time to detection of HLH was 20 days (IQR: 8-30 d). Of the 25 patients, 11 (44%) died. The erythrocyte sedimentation rates of the surviving and non-surviving patients were 39 ± 22 mm/h and 15 ± 13 mm/h, respectively. When a long-lasting fever is complicated by bicytopenia or pancytopenia (especially), clinicians should promptly consider the possibility of HLH syndrome to improve patients' prognosis.
RESUMO
OBJECTIVE: To investigate the molecular mechanisms of colistimethate sodium-induced nephrotoxicity and the protective effect of N-acetylcysteine (NAC) against nephrotoxicity. METHODS: Twenty-eight Wistar rats were divided into four groups comprised of control, colistin, NAC, and colistin-NAC co-treatment, respectively. Serum creatinine and urine N-acetyl-ß-d-glucosaminidase (NAG) levels were measured at different time intervals. Histological changes, apoptosis, total oxidant and antioxidant status, and the expression levels of endothelial nitric oxide synthase (eNOS), superoxide dismutase 2 (SOD2), and matrix metalloproteinase 3 (MMP3) were evaluated in renal tissue. RESULTS: In the colistin group, post-treatment creatinine levels were higher than pretreatment levels (p = .001). There was a significant increase in urine NAG level following colistin treatment on day 10, compared to the baseline value and the first day of treatment (p = .001 and .0001, respectively). Urine NAG levels were higher in the colistin group on the 10th day of treatment than in the other groups (p < .01). Colistin treatment increased the apoptosis index and renal histological damage score (RHDS) significantly and these changes were reversed in NAC co-treatment (RHSD and apoptosis index were 45 and 0 for sterile saline group, 29 and 2 for NAC group, 122 and 7 for colistin group, and 66 and 2 for colistin + NAC group). We observed no difference between groups regarding total antioxidant and total oxidant status in the kidneys. The expression levels of eNOS, SOD2, and MMP3 decreased significantly in the kidneys of colistin-treated rats; these changes were reversed in the kidneys of NAC co-treated rats. CONCLUSIONS: N-acetylcysteine prevented colistin-induced nephrotoxicity through activation of expression levels of SOD2, eNOS, and MMP3.

In this study, we aimed to determine the late relapse rate in hepatitis C patients with sustained virological response after interferon-based regimens, and evaluated the predictors of late relapse while comparing the real-life data of our country with that of others. A multicenter retrospective study was performed to investigate the data of patients infected with HCV who obtained sustained virological response after classical or pegylated interferon alpha (PegIFNα) and ribavirin (RBV) for 48 weeks. Sustained virological response was based on negative HCV RNA level by PCR at the end of six months after the therapy. The information of patients enrolled in the study was retrieved from the hospital computer operating system and outpatient follow-up archives. We evaluated the age, gender, HCV RNA levels, HCV genotype, six-month and further follow-up of patients with sustained virologic response, presence of cirrhosis, steatosis and relapse. In all, 606 out of 629 chronic hepatitis C patients (mean age was 53±12 years; 57.6% of them were female) with sustained virological response were evaluated. We excluded 23 patients who relapsed within six months after the end of treatment (EOT). The mean follow-up period of the patients was 71 months (range: 6-136) after therapy. Late relapse rate was 1.8% (n=11) in all patients. Univariate Cox proportional hazard regression models identified that cirrhosis and steatosis were associated with the late relapse [(p = 0.027; Hazard Ratio (HR) 2.328; 95% confidence interval (CI): 1.309-80.418), (p = 0.021; HR 1.446; 95% CI: 1.243-14.510, respectively]. In multivariable Cox regression analysis, steatosis was the only independent risk factor for late relapse (p = 0.03; HR 3.953; 95% CI: 1.146-13.635). Although the late relapse rate was approximately 2% in our study, clinicians should consider that pretreatment steatosis may be an important risk factor for late relapse.

Central nervous system infection caused by Human Herpesvirus 6 (HHV-6) is well known in immunocompromised; however, data regarding immunocompetent patients is limited to case series. We describe a 29-year-old immunocompetent pregnant woman with meningoencephalitis due to HHV-6 and review current literature. HHV-6 should be kept in mind in patients with meningoencephalitis of unknown etiology.

We present a 35-year-old female patient who was started on rifampicin (900 mg orally once daily) and trimethoprim/sulfamethoxazole (TMP/SMX) (160/800 mg orally twice daily) after being diagnosed with brucellosis. Following defervescence and improvement in her general condition, fever recurred on the 12th day of treatment. A re-challenge drug test lead to causality assessment and treatment was switched to a combination of streptomycin (1 g intramuscularly) for 10 days and TMP/SMX (160/800 mg orally twice daily) for 4 weeks. Our patient is doing well after 12 months of follow-up.
RESUMO
Epstein-Barr virus-associated haemophagocytic lymphohistiocytosis (EBV-HLH) is a life-threatening catastrophic and rarely seen complication of EBV infection especially in adults. While typical presentation of EBV infection is easily diagnosed as mononucleosis syndrome in teenagers and adults, some atypical clinical presentations may be challenged. We did not encounter any patient presenting with sudden sensorineural hearing loss associated with EBV infection in our English medical literature research (1966-2016). In this study, we report an adult patient who was complicated with EBV-HLH under high dose steroid therapy after diagnosis as sensorineural hearing loss. Our aim is to emphasise the atypical presentation of EBV infection and to discuss steroid therapy complication in sensorineural hearing loss that had been simply defined as idiopathic.

The aim of this study was to determine the clinical features, and outcome of the patients with miliary tuberculosis (TB).We retrospectively evaluated 263 patients (142 male, 121 female, mean age: 44 years, range: 16-89 years) with miliary TB. Criteria for the diagnosis of miliary TB were at least one of the followings in the presence of clinical presentation suggestive of miliary TB such as prolonged fever, night sweats, anorexia, weight loss: radiologic criterion and pathological criterion and/or microbiological criterion; pathological criterion and/or microbiological criterion.The miliary pattern was seen in 88% of the patients. Predisposing factors were found in 41% of the patients. Most frequent clinical features and laboratory findings were fever (100%), fatigue (91%), anorexia (85%), weight loss (66%), hepatomegaly (20%), splenomegaly (19%), choroid tubercules (8%), anemia (86%), pancytopenia (12%), and accelerated erythrocyte sedimentation rate (89%). Tuberculin skin test was positive in 29% of cases. Fifty percent of the patients met the criteria for fever of unknown origin. Acid-fast bacilli were demonstrated in 41% of patients (81/195), and cultures for Mycobacterium tuberculosis were positive in 51% (148/292) of tested specimens (predominantly sputum, CSF, and bronchial lavage). Blood cultures were positive in 20% (19/97). Granulomas in tissue samples of liver, lung, and bone marrow were present in 100% (21/21), 95% (18/19), and 82% (23/28), respectively. A total of 223 patients (85%) were given a quadruple anti-TB treatment. Forty-four (17%) patients died within 1 year after diagnosis established. Age, serum albumin, presence of military pattern, presence of mental changes, and hemoglobin concentration were found as independent predictors of mortality. Fever resolved within first 21 days in the majority (90%) of the cases.Miliary infiltrates on chest X-ray should raise the possibility of miliary TB especially in countries where TB is endemic. Although biopsy of the lungs and liver may have higher yield rate of organ involvement histopathologicaly, less invasive procedures including a bone marrow biopsy and blood cultures should be preferred owing to low complication rates.

AIM: To examine the variables associated with mortality in patients with Acinetobacter baumannii-related central nervous system infections treated with intrathecal colistin. MATERIALS AND METHODS: This multi-centre retrospective case control study included patients from 11 centres in Turkey, as well as cases found during a literature review. Only patients with CNS infections caused by multidrug-resistant or extensively drug-resistant Acinetobacter baumannii treated with intrathecal colistin were included in this study. The variables associated with mortality were determined by dividing the patients into groups who died or survived during hospitalisation, and who died or survived from Acinetobacter meningitis. RESULTS: Among the 77 cases enrolled in the study, 35 were found through a literature review and 42 were cases from our centres. Forty-four cases (57.1%) were male and the median age was 48 years (range: 20-78 years). Thirty-seven patients (48%) died during hospitalisation. The variables associated with increased all-cause mortality during hospitalisation included old age (odds ratio, 1.035; 95% confidence interval (CI), 1.004-1.067; p=0.026) and failure to provide cerebrospinal fluid sterilisation (odds ratio, 0.264; 95% confidence interval, 0.097-0.724; p=0.01). There is a trend (P=0.062) towards higher mortality with using of meropenem during meningitis treatment. Fifteen cases (19%) died from meningitis. There were no significant predictors of meningitis-related mortality. CONCLUSIONS: The mortality rate for central nervous system infections caused by multidrug-resistant or extensively drug-resistant Acinetobacter baumannii is high. Old age and failure to provide CSF sterilisation are associated with increased mortality during hospitalisation.

BACKGROUND/AIM: Broad-spectrum antibiotics have become available for use only with the approval of infectious disease specialists (IDSs) since 2003 in Turkey. This study aimed to analyze the tendencies of doctors who are not disease specialists (non-IDSs) towards the restriction of antibiotics. MATERIALS AND METHODS: A questionnaire form was prepared, which included a total of 22 questions about the impact of antibiotic restriction (AR) policy, the role of IDSs in the restriction, and the perception of this change in antibiotic consumption. The questionnaire was completed by each participating physician. RESULTS: A total of 1906 specialists from 20 cities in Turkey participated in the study. Of those who participated, 1271 (67.5%) had ≤5 years of occupational experience (junior specialists = JSs) and 942 (49.4%) of them were physicians. Specialists having >5 years of occupational experience in their branch expressed that they followed the antibiotic guidelines more strictly than the JSs (P < 0.05) and 755 of physicians (88%) and 720 of surgeons (84.6%) thought that the AR policy was necessary and useful (P < 0.05). CONCLUSION: This study indicated that the AR policy was supported by most of the specialists. Physicians supported this restriction policy more so than surgeons did.

BACKGROUND: Staphylococcus aureus is one of the causes of both community and healthcare-associated bacteremia. The attributable mortality of S. aureus bacteremia (SAB) is still higher and predictors for mortality and clinical outcomes of this condition are need to be clarified. In this prospective observational study, we aimed to examine the predictive factors for mortality in patients with SAB in eight Turkish tertiary care hospitals. METHODS: Adult patients with signs and symptoms of bacteremia with positive blood cultures for S. aureus were included. All data for episodes of SAB including demographics, clinical and laboratory findings, antibiotics, and outcome were recorded for a 3-year (2010-2012) period. Cox proportional hazard model with forward selection was used to assess the independent effect of risk factors on mortality. A 28-day mortality was the dependent variable in the Cox regression analysis. RESULTS: A total of 255 episodes of SAB were enrolled. The median age of the patients was 59 years. Fifty-five percent of the episodes were considered as primary SAB and vascular catheter was the source of 42.1 %. Healthcare associated SAB was defined in 55.7 %. Blood cultures yielded methicillin-resistant S. aureus (MRSA) as a cause of SAB in 39.2 %. Initial empirical therapy was inappropriate in 28.2 %. Although overall mortality was observed in 52 (20.4 %), 28-day mortality rate was 15.3 %. Both the numbers of initial inappropriate empirical antibiotic treatment and the median hours to start an appropriate antibiotic between the cases of fatal outcome and survivors after fever onset were found to be similar (12/39 vs 60/216 and 6 vs 12 h, respectively; p > 0.05). High Charlson comorbidity index (CCI) score (p = 0.002), MRSA (p = 0.017), intensive care unit (ICU) admission (p < 0.001) and prior exposure to antibiotics (p = 0.002) all were significantly associated with mortality. The Cox analysis defined age [Hazard Ratio (HR) 1.03; p = 0.023], ICU admission (HR 6.9; p = 0.002), and high CCI score (HR 1.32; p = 0.002) as the independent predictive factors mortality. CONCLUSIONS: The results of this prospective study showed that age, ICU stay and high CCI score of a patient were the independent predictors of mortality and MRSA was also significantly associated with mortality in SAB.

BACKGROUND: Fatty liver is a common disease in developed countries. We investigated the frequency of operation in patients with fatty liver and the frequency of cancer in their first-degree relatives. METHODS: In this study, we evaluated 105 patients with biopsy-proven nonalcoholic fatty liver disease (NAFLD), 121 patients with hepatitis C (61 patients with fatty liver and 60 patients without fatty liver), 50 patients with inflammatory bowel disease (IBD), and 109 patients with dyspepsia as a control group. RESULTS: There was no difference for sex, mean age, and marital status among the groups, except that patients with IBD were younger than others (p < 0.001). The frequency of cancer in family was as follows: 18 % in IBD, 9 % in dyspepsia, 28 % in hepatitis C with hepatic steatosis, 21.5 % in hepatitis C without steatosis, and 27 % in NAFLD (p = 0.006). Then, we divided the study group into two groups-group 1: IBD + dyspepsia + hepatitis C without hepatic steatosis, and group 2: hepatitis C with hepatic steatosis + NAFLD-and performed the same analysis. We found that the frequency of cancer in family was 16 % in group 1 (the patients without fatty liver) vs. 24.4 % in group 2 (those with fatty liver; p = 0.037). We also investigated the rate of operation in patients. The results were as follows: 33 % in group 1 vs. 43 % in group 2 (p = 0.043). CONCLUSIONS: Independently of the underlying chronic diseases, occurrence of fat in the liver increased the frequency of operation in patients with fatty liver and the rate of cancer in their first-degree relatives. Understanding the underlying causes of fatty liver forms might decrease the cancer frequency in the population and number of operation in patients with fatty liver.

BACKGROUND: We examined the changes of mean platelet volume (MPV) and platelet distribution width (PDW) in subjects with appendicitis and whether MPV and PDW could be used to predict the development of complication due to appendicitis. METHODS: The healthy control group, the cases of appendicitis with perforation, and the cases of appendicitis without perforation were compared with regard to MPV and PDW. We determined whether MPV and PDW were independent variables predictive of the development of complication in subjects with appendicitis. RESULTS: This retrospective case-control study included a total of 362 patients (249 of which were male (68.8 %) and 113 were female (31.2 %); median age, 30 [range, 18-84 years]). One hundred and ninety-two subjects (53 %) presented with appendicitis and 170 (47 %) comprised the healthy control group. Sixty-six (18.2 %) of the subjects with appendicitis developed complication. MPVs were lower in subjects of appendicitis without complication compared to the subjects of appendicitis with complication and the control group (MPV, 9.78 ± 0.99 vs. 10.20 ± 1.21 and 10.14 ± 1.03, respectively [p = 0.005]). The PDW levels were not different between the three groups. Independent variables predictive of the presence of complication included increased MPV and time from onset of symptoms to hospital presentation (odds ratio[confidence interval], p-value: 1.507[1.064-2.133], 0.021 and 18.887[5.139-69.410], 0.0001, respectively). CONCLUSIONS: Our findings suggested these, MPV values in cases of appendicitis without complication were lower than the cases with complication and healthy control and MPV is a predictor of the development of complication in subjects with appendicitis.

AIM: The aim of this study was to identify the predictors of acute renal injury associated with colistin treatment. METHODS: The patients who received treatment with colistin for more than 3 days were included in this retrospective cohort study. Acute renal injury was defined by the RIFLE (Risk Injury Failure Loss End stage renal disease) criteria. Patients whose serum creatinine levels increased at least 1.5-fold compared with baseline value were considered as cases with renal injury. The independent variables determining the development of acute renal injury were investigated by survival analysis. RESULTS: A total of 112 cases [67 (59.8 %) were male, median age 64 (range: 18-93) years] were included in the study. Acute renal injury occurred in 66 (58.9 %) patients. Renal injury developed in first 7 days of the colistin therapy in 52 (78.8 %) cases and at day 8-23 in 14 (21.2 %) cases. On the day with highest levels of creatinine, 25 (22.3 %), 17 (15.2 %), and 33 (29.5 %) cases were in 'Risk', 'Injury', and 'Failure' group, respectively, according to RIFLE criteria. We identified three independent risk factors predicting acute colistin-induced renal injury: advanced age, low serum albumin levels, and high serum total bilirubin levels [odds ratio (confidence interval) = 1.022 (1.006-1.037), 0.643 (0.415-0.994), and 1.129 (1.014-1.257), respectively]. CONCLUSIONS: The advanced age, low serum albumin levels, and high serum total bilirubin levels are independent risk factors for colistin-induced nephrotoxicity.

HIV-1 replication is rapid and highly error-prone. Transmission of a drug-resistant HIV-1 strain is possible and occurs within the HIV-1-infected population. In this study, we aimed to determine the prevalence of transmitted drug resistance mutations (TDRMs) in 1,306 newly diagnosed untreated HIV-1-infected patients from 21 cities across six regions of Turkey between 2010 and 2015. TDRMs were identified according to the criteria provided by the World Health Organization's 2009 list of surveillance drug resistance mutations. The HIV-1 TDRM prevalence was 10.1% (133/1,306) in Turkey. Primary drug resistance mutations (K65R, M184V) and thymidine analogue-associated mutations (TAMs) were evaluated together as nucleos(t)ide reverse transcriptase inhibitor (NRTI) mutations. NRTI TDRMs were found in 8.1% (107/1,306) of patients. However, TAMs were divided into three categories and M41L, L210W, and T215Y mutations were found for TAM1 in 97 (7.4%) patients, D67N, K70R, K219E/Q/N/R, T215F, and T215C/D/S mutations were detected for TAM2 in 52 (3.9%) patients, and M41L + K219N and M41L + T215C/D/S mutations were detected for the TAM1 + TAM2 profile in 22 (1.7%) patients, respectively. Nonnucleoside reverse transcriptase inhibitor-associated TDRMs were detected in 3.3% (44/1,306) of patients (L100I, K101E/P, K103N/S, V179F, Y188H/L/M, Y181I/C, and G190A/E/S) and TDRMs to protease inhibitors were detected in 2.3% (30/1,306) of patients (M46L, I50V, I54V, Q58E, L76V, V82A/C/L/T, N83D, I84V, and L90M). In conclusion, long-term and large-scale monitoring of regional levels of HIV-1 TDRMs informs treatment guidelines and provides feedback on the success of HIV-1 prevention and treatment efforts.

BACKGROUND/AIMS: We aimed to evaluate the impact of non-alcoholic fatty liver disease (NAFLD) on viral kinetics and virologic response to tenofovir and entecavir treatment in patients with chronic hepatitis B virus (HBV) infection. MATERIALS AND METHODS: This study was designed as a retrospective multicenter cohort study. The impact of hepatosteatosis on pre-treatment serum HBV DNA levels and also on the virologic response to either tenofovir or entecavir at 6 and 12 months of therapy was investigated. RESULTS: A total of 145 cases were involved in the study [median age 40 (18-73) years, 90 (62%) males]. In multivariate analysis, it was detected that patients with NAFLD were older and had a higher body mass index (BMI) [Odds ratio (95% confidence interval) and p-value for age were 1.040 (1.003-1.079) and 0.033 and for BMI were 1.348 (1.190-1.528) and 0.0001, respectively]. When only the 43 patients who were younger than 35.5 years old and who had a BMI less than 27.59 were investigated, serum high-density lipoprotein (HDL) levels and serum HBV DNA levels were lower in patients with NAFLD in multivariate analysis [Odds ratio (95% confidence interval) and p-values for serum HDL level and HBV DNA level were 0.864 (0.061-0.980) and 0.023 and 0.995 (0.990-0.999) and 0.025, respectively]. Totally, 57 and 75 of the patients had received entecavir and tenofovir, respectively. CONCLUSION: Viral replication decreases in patients with chronic HBV infection in the presence of NAFLD, and NAFLD had no impact on the virologic response to entecavir and tenofovir treatment.

INTRODUCTION: Although pegylated interferons (pegIFNs) alpha-2a and alpha-2b have been used in chronic hepatitis B (CHB) treatment for many years, there are few studies concerning predictors of sustained virologic response (SVR) to pegIFN therapy. In this study, we aimed to investigate the predictors of response to pegIFN treatment in cases with HBeAg-negative CHB infection. METHODOLOGY: Seventeen tertiary care hospitals in Turkey were included in this study. Data from consecutively treated HBeAg-negative CHB patients, who received either pegIFN alpha-2a or alpha-2b, were collected retrospectively. SVR is defined as an HBV DNA concentration of less than 2,000 IU/mL six months after the completion of therapy RESULTS: SVR was achieved in 40 (25%) of the 160 HBeAg-negative CHB patients. Viral loads in patients with SVR were lower compared to those with no SVR, beginning in the third month of treatment (p < 0.05). The number of cases with a decline of 1 log10 IU/mL in viral load after the first month of treatment and with a serum HBV DNA level under 2,000 IU/mL after the third month of treatment was higher in cases with SVR (p < 0.05). The number of patients who had undetectable HBV DNA levels at week 48 among responders was significantly greater than among post-treatment virological relapsers (p < 0.05). CONCLUSIONS: Detection of a 1 log10 decline in serum HBV DNA level at the first month of treatment and a serum HBV DNA level < 2000 IU/mL at the third month of therapy may be predictors of SVR.
