Neurocognitive Disorders in HIV-positive Patients.

Human immunodeficiency viruses (HIV) associated neurocognitive disorders (HAND) encompasses a group of syndromes of various degrees of impairment in cognition and daily functioning of HIV positive individuals. Although the widespread use of highly active antiretroviral therapy (HAART) has drastically reduced the prevalence of severe form of HAND, like HIV associated dementia (HAD), the prevalence of HAND and associated morbidity remains high. OBJECTIVES: (1) To know the prevalence of HAND in HIV-infected patients of a multi-ethnic population. (2) To describe various types of neurocognitive impairment among patients of HAND and study the factors affecting HAND. STUDY DESIGN: This study was a cross-sectional descriptive study conducted on 250 HIV-positive patients in outpatient department (OPD) of a tertiary care center in Mumbai, conducted over a period of 12 months. Patients with HIV-1 attending the OPD and having a minimal formal education of 4 years were included. Patients with concomitant delirium, any known central nervous system (CNS) disorder, any psychiatric disorder, and pregnant females were excluded. Outcome measures-the test batteries used were (1) International HIV Dementia Scale (IHDS) and (2) Addenbrookes cognitive examination-revised (ACE-R) scale. RESULTS: Of 250 subjects studied, 55.6% (139) were males and 44.4 % (111) were females. The mean age of study population was 39.42 years. The mean years of education were 8.32 years. The mean duration of infection (diagnosis of HIV-positive state) was 64.49 months and the mean duration of HAART intake in our patients was 52.30 months. The mean cluster of differentiation 4 (CD4) counts of our subjects were 527.13 per cumm [standard deviation (SD) of 234.13]. The mean nadir CD4 counts were 224.35 per cumm (SD of 115.09). Using the ACE-R scale, the prevalence of HAND was 71.60%, of which 37.20% had an asymptomatic neurological impairment, 29.60% had mild cognitive dysfunction, and 4.80% had HAD. Memory, verbal fluency and visuospatial abilities were the most affected domains on the ACE-R and memory recall and psychomotor speed were affected more on the IHDS. The prevalence of HAND was more with increasing age (p = 0.020), lesser education (p < 0.00) and lesser nadir CD4 counts (p < 0.00). However, it was not affected by the duration of the disease and the current CD4 counts (p > 0.05). CONCLUSION: Human immunodeficiency viruses (HIV) associated neurocognitive disorders HAND is common in HIV-positive patients, most of whom are asymptomatic. Older patients with less education and severe disease, having lower nadir counts are at the highest risk of HAND. Memory, verbal fluency, and visuospatial abilities were the most commonly affected domains.

Saroglitazar for Nonalcoholic Fatty Liver Disease: A Single Centre Experience in 91 Patients.

Background: Saroglitazar is a novel, dual peroxisome proliferator-activated receptors-α/γ agonist and is being investigated for the treatment of nonalcoholic fatty liver disease (NAFLD). Patients and methods: Consecutive overweight (body mass index [BMI] >23 kg/m2) patients of NAFLD, diagnosed based on controlled attenuation parameter (CAP) >248 dB/m, and attending the outpatient department of a tertiary care centre in New Delhi, were enrolled. Patients with cirrhosis (liver stiffness measurement [LSM] >13.5 kPa) and those with concomitant liver disease due to other aetiologies (alcohol, viral, etc.) were excluded. All patients received saroglitazar 4 mg/day; in addition, they were advised to reduce weight and were counselled regarding diet and exercise. At 3-month follow-up, patients were categorized into those who were able to reduce ≥5% body weight and those who could n'ot, and both these groups were compared. Results: A total of 91 patients (median age 45 years [range 18-66 years]; 81% men) were included in the study. The median BMI was 29.3 kg/m2 (range 23.6-42.2 kg/m2). The baseline median (range) aspartate transaminase, alanine transaminase, gamma glutamyl transferase, LSM and CAP values were 40 IU/dL (range 22-144 IU/dL), 48 IU/dL (range 13-164 IU/dL), 42 IU/dL (range 4-171 IU/dL), 6.7 kPa (range 3.6-13.1 kPa), and 308 dB/m (range 249-400 dB/m). All patients tolerated saroglitazar well. At 3-month, 57 patients (63%) were able to reduce ≥5% weight, whereas in the remaining 34 patients (37%), the weight reduction was <5% from baseline. Transaminases values improved in both the groups; however, LSM and CAP values improved only in patients who reduced weight. Conclusion: In overweight patients with NAFLD, a 3-month therapy with saroglitazar is able to improve transaminases but not LSM and CAP values unless accompanied by weight reduction of at least 5%. Larger randomized controlled trials are needed to document the independent effect of saroglitazar in these patients.

Role of Helicobacter pylori eradication in patients with functional dyspepsia.

BACKGROUND: Helicobacter pylori (H. pylori) is implicated in the pathogenesis of functional dyspepsia (FD). There is conflicting data regarding the benefit of H. pylori eradication for symptom relief in FD. AIMS: To study the benefit of eradicating H. pylori in patients with FD as compared to standard medical treatment (SMT). Secondary aims were to find efficacy of H. pylori eradication therapy, recurrence of H. pylori after eradication, and predictors of efficacy. METHODS: Consecutive adult patients of FD (ROME IV) with H. pylori infection presenting in the outpatient department of our hospital were enrolled. Patients with Global Overall Symptom (GOS) scale > 2 and H. pylori infection were included. Patients were randomized into two groups: group 1 received H. pylori eradication therapy and group 2 received SMT. Treatment success was defined as symptom relief (GOS score < 2 and reduction by at least 2 points at 6 months) and H. pylori eradication was defined as stool antigen negative at 4 weeks. RESULTS: Of 329 participants with FD, 253 were H. pylori positive (rapid urease test and stool antigen test) (76.89%). After exclusions, 202 were randomized into two groups of 101 each. Thirty-two patients in group 1 and 31 in group 2 had treatment success (31.7% vs. 30.7%, p=1.000). The efficacy of H. pylori eradication therapy was 74.46% (70/94). H. pylori reinfection rate was 26.02% (19/73). CONCLUSIONS: H. pylori eradication therapy does not provide additional benefit in symptom relief in patients with FD as compared with SMT.
