RESUMO

BACKGROUND: A three-dose, oral rotavirus vaccine (Rotavac) was introduced in the universal immunization program in India in 2016. A prelicensure trial involving 6799 infants was not large enough to detect a small increased risk of intussusception. Postmarketing surveillance data would be useful in assessing whether the risk of intussusception would be similar to the risk seen with different rotavirus vaccines used in other countries. METHODS: We conducted a multicenter, hospital-based, active surveillance study at 27 hospitals in India. Infants meeting the Brighton level 1 criteria of radiologic or surgical confirmation of intussusception were enrolled, and rotavirus vaccination was ascertained by means of vaccination records. The relative incidence (incidence during the risk window vs. all other times) of intussusception among infants 28 to 365 days of age within risk windows of 1 to 7 days, 8 to 21 days, and 1 to 21 days after vaccination was evaluated by means of a self-controlled case-series analysis. For a subgroup of patients, a matched case-control analysis was performed, with matching for age, sex, and location. RESULTS: From April 2016 through June 2019, a total of 970 infants with intussusception were enrolled, and 589 infants who were 28 to 365 days of age were included in the self-controlled case-series analysis. The relative incidence of intussusception after the first dose was 0.83 (95% confidence interval [CI], 0.00 to 3.00) in the 1-to-7-day risk window and 0.35 (95% CI, 0.00 to 1.09) in the 8-to-21-day risk window. Similar results were observed after the second dose (relative incidence, 0.86 [95% CI, 0.20 to 2.15] and 1.23 [95% CI, 0.60 to 2.10] in the respective risk windows) and after the third dose (relative incidence, 1.65 [95% CI, 0.82 to 2.64] and 1.08 [95% CI, 0.69 to 1.73], respectively). No increase in intussusception risk was found in the case-control analysis. CONCLUSIONS: The rotavirus vaccine produced in India that we evaluated was not associated with intussusception in Indian infants. (Funded by the Bill and Melinda Gates Foundation and others.).

RESUMO

BACKGROUND: Myocardial iron deposition is a significant cause of morbidity and mortality in patients with transfusion-dependent thalassemia (TDT). Amlodipine, L-type calcium channel blocker with regular chelation therapy may reduce myocardial iron overload. Lack of randomized trials prompted this study to assess the effect of calcium channel blocker (amlodipine) in combination with iron chelation therapy on iron overload in patients with TDT. METHODS: Sixty-four eligible patients were randomized to receive either amlodipine and chelation (group A) or chelation alone (group B) in double-blind placebo-controlled trial. Myocardial iron concentration (MIC) using T2* magnetic resonance imaging (MRI), liver iron concentration (LIC), left ventricular ejection fraction (LVEF), and serum ferritin were measured at baseline and 12 months. RESULTS: In the amlodipine group, mean cardiac T2* value significantly increased from 18.11 ± 8.47 to 22.15 ± 7.61 (p = .002) at 12 months, whereas in control group, there was a nonsignificant increase (p = .62) in cardiac T2* value from 19.50 ± 8.84 to 20.03 ± 9.07. There was a significant decrease in MRI-derived MIC in the amlodipine group compared to control group (1.93 ± 1.61 to 1.29 ± 0.90, p = .01). Changes in the LVEF (p = .45), MRI-derived LIC (p = .09), and serum ferritin (p = .81) were not significant between the two groups. CONCLUSION: Amlodipine is safe and when combined with chelation therapy appears to be more effective in reducing cardiac iron overload than chelation only in children and young adults with TDT.

RESUMO

OBJECTIVE: The aim of this study was to evaluate levels of vitamin D, bone mineral density (BMD), and radiograph features at diagnosis and after 6 months of chemotherapy in patients with acute lymphoblastic leukemia (ALL). Vitamin D levels were also correlated with BMD and radiograph features. MATERIALS AND METHODS: 25-Hydroxy vitamin D [25(OH)D] levels, BMD, and radiograph features were assessed in 50 newly diagnosed patients of ALL in the age group of 2 to 14 years. A total of 30 age-matched and sex-matched children were recruited as controls. Vitamin D deficiency was defined as 25(OH)D <10 ng/mL, Vitamin D insufficiency as 10 to 29 ng/mL, and Vitamin D sufficiency as ≥30 ng/mL. Enzyme immunoassay (EIA) was used for the quantitative measurement of 25(OH)D levels in plasma and a LUNAR DPX NT bone densitometer was used for the assessment of BMD. RESULTS: The mean age of the patients was 6.3 years, with a male:female ratio of 1.38:1. The mean 25(OH)D levels were 31.90±16.90 ng/mL in patients at diagnosis against 41.63±20.50 ng/mL in controls (P=0.02). Levels were 18.50±11.10 ng/mL postchemotherapy (P=0.00). Female sex was a risk factor for deficient 25(OH)D levels. There was a significant decrease in BMD postchemotherapy in the age groups of 5 to 10 and above 10 years at the femoral neck. Osteopenic changes were observed in more number of patients after 6 months of chemotherapy. There was a significant correlation between vitamin D levels, BMD, and osteopenic changes. CONCLUSIONS: Vitamin D deficiency was common among ALL patients, which worsened after chemotherapy. This had a significant correlation with BMD and osteopenic changes in radiograph.

RESUMO

BACKGROUND/OBJECTIVES: Cardiac T2* magnetic resonance imaging (MRI) is the gold standard to determine myocardial iron overload. As availability of Cardiac T2* is not uniform across developing nations, our strategy was to identify a more accessible and cost effective tool to assess myocardial iron accumulation. As children with transfusion-dependent thalassemia also experience various electrocardiographic abnormalities, we performed electrocardiography (ECG) as well as Cardiac T2* MRI on all children registered in our thalassemia unit. MATERIALS AND METHODS: Forty-eight transfusion-dependent thalassemia children with transfusion burden ≥12 times/y (6 to 19 y) in the Thalassemia Unit of the Division of Hematology Oncology, Department of Pediatrics were enrolled. Patients were divided into 3 groups based on severity of T2* value, that is group I (T2*<10), group II (T2* 10 to 20), group III (T2*>20). A T2* value >20 was taken as normal. ECG and serum ferritin was also performed on the day of MRI. RESULTS: Among the various ECG parameters, QRS duration, and QTc interval were significantly increased if cardiac iron overload was high with a P-value of 0.036 and 0.000, respectively. Also, high serum ferritin predicted a decline in T2* value with a P-value of 0.001. QT interval and QTc interval significantly correlated inversely with T2* (P=0.042, r=-0.295 and P=0.002, r=-0.446, respectively) but not QRS duration (P=0.05, r=-0.282). Serum ferritin also was found to have a significant inverse correlation with T2* value (P=0.000, r=-0.497). CONCLUSIONS: Abnormalities on ECG, that is prolongation of QRS duration, QT interval, and QTc interval were significantly associated with cardiac iron overload, that is decrease in the value of Cardiac T2* in our study.

RESUMO

BACKGROUND: Several measures including drugs have been tried to reduce anthracycline cardiotoxicity. The lack of randomized trials prompted this study to assess the role of an angiotensin converting enzyme (ACE) inhibitor (enalapril) in anthracycline-induced cardiotoxicity in children with hematological malignancies. METHODS: A randomized, double-blind, placebo-controlled trial was conducted on 84 patients with leukemia (41) and lymphoma (43) who received anthracyclines (doxorubicin and/or daunorubicin) at cumulative dose ≥200 mg/m2 . The patients were randomized to receive either enalapril [group A (n = 44)] or placebo [group B (n = 40)] for 6 months. Left ventricular ejection fraction (LVEF) and cardiac biomarkers (cardiac troponin I [cTnI], probrain natriuretic peptide [proBNP], and creatine kinase MB [CK-MB]) were assessed at baseline and 6 months. The primary outcome was a measured decrease in LVEF (≥20%). Secondary outcome measures were changes in cardiac biomarkers and the development of heart failure or arrhythmias. RESULTS: LVEF decreased in both groups at 6 months, more so in group B (62.25 ± 5.49 vs 56.15 ± 4.79, P < 0.001). A ≥20% decrease was seen in 3 patients in group B but none in group A (P = 0.21). Cardiac biomarkers increased more in group B at 6 months, and the increase was significant for proBNP (49.60 ± 35.97 vs 98.60 ± 54.24, P < 0.001) and cTnI (0.01 ± 0.00 vs 0.011 ± 0.003, P = 0.035) but not significant for CK-MB (1.08 ± 0.18 vs 1.21 ± 0.44, P = 0.079). In group A, 9.1% of the patients showed an increase in proBNP level ≥100 compared with 37.5% in group B (P < 0.001). No patient developed heart failure or arrhythmia. CONCLUSION: Enalapril has a role in reducing cardiac toxicity after anthracycline administration.

RESUMO

AIM: The aim of this study was to evaluate the levels of interleukin (IL)-6 and IL-8 in patients with aplastic anemia and its correlation with severity of the disease. MATERIALS AND METHODS: IL-6 and IL-8 levels were measured in 40 patients with aplastic anemia in the age group of 4 to 14 years. A total of 40 healthy children served as controls. Quantitative estimation of IL-6 and IL-8 was performed using a solid-phase sandwich ELISA kit. Results were presented as IL-6 and IL-8 concentrations in pg/mL. Patients received immunosuppressive therapy per the British Committee for Standards in Haematology Guidelines 2009. RESULTS: Mean age of the patients was 9.78±2.74 years. IL-6 level of patients was elevated compared with controls (193.48±352.3 vs. 4.58±3.39; P<0.001). IL-8 levels were also significantly elevated in patients compared with controls (15.58±18.0 vs. 1.85±0.95; P<0.001). IL levels were also assessed in relation to severity of the disease. Levels were the highest in patients with very severe aplastic anemia (724.33±519.42), followed by severe aplastic anemia (80.51±66.28 pg/mL), and non-severe aplastic anemia (6.01±1.89). Differences were statistically significant. A similar trend was also observed for IL-8 levels, where the levels were 41.02±24.23, 11.34±8.0, and 1.67±0.71 for very severe aplastic anemia, severe aplastic anemia, and non-severe aplastic anemia, respectively. The differences were again statistically significant. IL levels were also correlated with the treatment outcome. Responders had lower levels compared with nonresponders, but the difference was not statistically significant (186.36±322.45 vs. 198.74±368.10). Levels of ILs decreased in responders, but were not comparable with that of controls 6 months after therapy. CONCLUSIONS: High levels of IL-6 and IL-8 were observed in children with aplastic anemia. Increased levels showed correlation with disease severity and therefore appear to play an important role in aplastic anemia. However, levels had no significant correlation with the treatment outcome.

RESUMO

BACKGROUND: Various uses of metals in industries, including the domestic sphere, agriculture, medicine and technology, have led to their wide distribution in the environment. These result in raising concerns over their potential effects on human health and the environment. Because of their high degree of toxicity, Cd, Cr and Pb are some of the priority metals that are of public health significance. The levels of Cd, Cr, Pb and Ni were measured in Parkinson's disease (PD) patients. METHODS: Blood samples were collected from 40 patients and 40 healthy controls, and stored at -80 °C until assayed. Atomic absorption spectrophotometry was used to determine the levels of metals. RESULTS: The level of Pb was significantly decreased in patients than in controls. However, the difference in the level of Ni between patients and controls failed to reach significance. Cr was not detectable in patients, but it was measurable in 12 controls (controls = 0.056-2.397 µg/ml). Similarly, Cd was not detectable in patients, but it was measurable in all the controls (controls = 0.004-1.268 µg/ml). Pb was the only metal that was found in all study participants (PD = 0.012-2.758 µg/ml and controls = 0.779-9.840 µg/ml). Ni could be measured only in six patients and in all the controls (PD = 0.154-0.754 µg/ml and controls = 0.034-1.691 µg/ml). CONCLUSION: Patients exhibited significantly decreased levels of Pb than in controls. However, Cd, Cr and Ni were too low to be measured among the patients. This indicates that these metals might play a probable role in PD.

RESUMO

AIM: The aim of the study was to evaluate the levels of vitamin D in patients of aplastic anemia presenting with febrile neutropenia and its association with clinically important parameters. MATERIALS AND METHODS: The 25-hydroxy vitamin D (25(OH)D) levels were measured in 35 patients of aplastic anemia with febrile neutropenia in the age group of 4 to 16 years. About 30 healthy children served as controls. Vitamin D deficiency was defined as 25(OH)D<20 ng/mL, insufficiency 20 to 29 ng/mL, and sufficiency≥30 ng/mL. RESULTS: The median age of patients was 9.3 years. The mean 25(OH)D level was 17.71±8.90 ng/mL in patients against 23.67±10.80 ng/mL in the control group (P<0.01). About 65.7% of the patients were 25(OH)D deficient (<20 ng/mL). Only 8.6% had sufficient levels. Older (above 10 y) patients, male children, and those from a rural background and a low socioeconomic status had significantly lower 25(OH)D levels as compared with controls. Low 25(OH)D levels were associated with a longer duration (≥7 d) of febrile neutropenia (17.26±7.19 vs. 20.01±12.12 ng/mL) although the difference was not statistically significant. Two patients who expired had significantly lower 25(OH)D levels (12.85±4.12 ng/mL) compared with those who improved (22.86±6.47 ng/mL, P<0.05). CONCLUSIONS: A high prevalence of vitamin D deficiency was observed in patients with febrile neutropenia. Low levels were associated with an adverse clinical outcome.

RESUMO

Lymphomas predominantly affect the lymph nodes but can present at unusual sites, which are termed as extranodal lymphomas. Involvement of the ocular adnexa is an extremely uncommon occurrence, which is usually seen in patients with non-Hodgkin lymphoma. We report herewith an unusual case of a 5-year-old child with Hodgkin lymphoma and involvement of extraocular muscle leading to ptosis. The child was managed by alternating cycles of cyclophosphamide, vincristine, procarbazine and prednisolone and adriamycin, bleomycin, vinblastine, and dacarbazine. He had complete response to chemotherapy with resolution of ptosis.

RESUMO

BACKGROUND: Several types of proteinases are implicated in extracellular matrix (ECM) degradation, but the major enzymes are considered to be matrix metalloproteinases (MMPs). Matrix metalloproteinase-1 (MMP-1) is a major proteinase of the MMP family. MMP-1 is critical for modeling and remodeling of the extracellular matrix. In the present study, we evaluated circulating level of MMP-1 in Parkinson's disease (PD) patients and controls. METHOD: Enzyme linked immunosorbent assay (ELISA) was used to determine the serum level of MMP-1 in Parkinson's patients and matched healthy controls. RESULTS: The mean age of Parkinson's patients (65%) and controls (62.5%) were 55.80 ± 9.69 and 54.05 ± 8.71 years respectively, with similar male/female ratio between patients and controls. The MMP-1 level was (p = 0.005) significantly lower in Parkinson's patients (2380.32 ± 2245.27 pg/ml) as compared to controls (4453.07 ± 3321.01 pg/ml). Poor correlation was found between MMP-1 level and disease duration (r = 0.36, p = 0.02), however it was statistically significant. CONCLUSION: Significantly lower level of serum MMP-1 was found in PD patients in comparison to controls. This difference in MMP-1 level was more prominent in females.

RESUMO

Rabadi is a cereal and buttermilk based traditional fermented recipe of western region of India. There are many traditional preparation methods, which may alter biochemical composition of rabadi, therefore, in the present study, role of traditional processings (cooking, fermentation, dehulling, utensil, preparation methods and cereals) on minerals and antinutrients of pearl millet, wheat flour and refined wheat flour rabadi was investigated on fresh weight basis. Results showed that the process of cooking and fermentation enhanced minerals (Ca, Fe and P) in all types of rabadi samples at different levels of significance, while antinutrients (phytic acid, total phenols and oxalates) reflected a declining trend. Intercomparison of different types of rabadies exhibited that fermented- cooked -fermented samples were better than cooked -fermented rabadies. Dehulling caused a loss of minerals, but antinutrients were also degraded after dehulling; therefore dehulled sample showed very good nutritional profile after fermentation. Earthen pot rabadi samples presented better biochemical composition than rabadies prepared in steel pot. Intercomparison of different cereals based rabadies reflected superior position of fermented -cooked- fermented pearl millet flour rabadi than cooked- fermented pearl millet flour rabadi, wheat and refined wheat flour rabadi samples.

RESUMO

OBJECTIVE: Patients with transfusion-dependent thalassemia (TDT) are at risk of developing pulmonary artery hypertension (PAH) due to chronic hemolysis, iron overload, hypercoagulability and splenectomy. The objective of the study was to assess the prevalence and predictors of PAH in patients with TDT. METHODS: Patients aged 6-18 years with TDT were included. 2D-echocardiography was done to measure the pulmonary artery systolic pressure (PASP) and left ventricular ejection fraction (LVEF). T2* MRI was done to evaluate cardiac iron overload. N-terminal-pro brain natriuretic peptide (NT-pro BNP) level was also assessed. RESULTS: Out of 61 participants, PAH was noted in 19 (31.6%). Mean (SD) age of the patients with PAH and without PAH was 12.2 (3.8) and 9.6 (3.5) years, respectively (P = 0.016). Five of 19 patients with PAH (26.3%) had undergone splenectomy as against 5 of 41 patients without PAH (12.2%) (P = 0.17). Years since splenectomy was higher in the PAH group. Mean (SD) NT-Pro BNP levels were also higher in patients with PAH [63.80 (25.89) vs 41.97 (23.95), P = 0.01]. Significantly higher number of patients with PAH had cardiac T2* value of < 10 ms (P = 0.04). Age (OR 4.11; 95% CI 1.46-8.77), years since splenectomy (OR 3.24; 95% CI 1.30-7.86), NT-Pro BNP levels (OR 4.43; 95% CI 2.14-9.61) and cardiac T2* MRI (OR 2.46; 95% CI 2.18-6.90) values were predictors of PAH in patients with TDT. CONCLUSION: PAH was observed in 31.6% of patients, with older age and years since splenectomy being important risk factors. NT-Pro BNP can be used as screening test for detecting PAH.

RESUMO

Background: The purpose of this study is to explore the effect of vitamin B complex supplementation following periodontal flap surgery on clinical and microbiological parameters. Materials and Methods: A randomized controlled trial on 10 patients with periodontitis in split-mouth design was undertaken to find the effect of vitamin B complex supplementation with open flap debridement on periodontal wound healing. Multiplex polymerase chain reaction (PCR) for Tannerella forsythus and Porphyromonas gingivalis was done using subgingival plaque samples at 0 and 90th day. Results: The results showed a significant reduction (P < 0.01) of clinical (plaque index, gingival index, gingival bleeding index, probing pocket depth, and relative attachment level) and microbial profile in both treatment groups, whereas on intergroup analysis, more reduction in all clinical parameters were observed in the test group, but statistically, the results were insignificant.

RESUMO

BACKGROUND & OBJECTIVES: Aplastic anaemia is a rare haematological disorder characterized by pancytopenia with a hypocellular bone marrow. It may be inherited/genetic or acquired. Acquired aplastic anaemia has been linked to many drugs, chemicals and viruses. Cytogenetic abnormalities have been reported infrequently with acquired aplastic anaemia. Majority of the studies are in adult patients from the West. We report here cytogenetic studies on paediatric patients with acquired aplastic anaemia seen in a tertiary care hospital in north India. METHODS: Patients (n=71, age 4-14 yr) were diagnosed according to the guidelines of International Agranulocytosis and Aplastic Anaemia Study. Conventional cytogenetics with Giemsa Trypsin Giemsa (GTG) banding was performed. Karyotyping was done according to the International System for Human Cytogenetics Nomenclature (ISCN). RESULTS: Of the 71 patients, 42 had successful karyotyping where median age was 9 yr; of these 42, 27 (64.3%) patients had severe, nine (21.4%) had very severe and six (14.3%) had non severe aplastic anaemia. Five patients had karyotypic abnormalities with trisomy 12 (1), trisomy 8 (1) and monosomy 7 (1). Two patients had non numerical abnormalities with del 7 q - and t (5:12) in one each. Twenty nine patients had uninformative results. There was no difference in the clinical and haematological profile of patients with normal versus abnormal cytogenetics although the number of patients was small in the two groups. INTERPRETATION & CONCLUSIONS: Five (11.9%) patients with acquired aplastic anaemia had chromosomal abnormalities. Trisomy was found to be the commonest abnormality. Cytogenetic abnormalities may be significant in acquired aplastic anaemia although further studies on a large sample are required to confirm the findings.

RESUMO

BACKGROUND: Arsenic is widely distributed in the environment and has been found to be associated with the various health related problems including skin lesions, cancer, cardiovascular and immunological disorders. The fruit extract of Emblica officinalis (amla) has been shown to have anti-oxidative and immunomodulatory properties. In view of increasing health risk of arsenic, the present study has been carried out to investigate the protective effect of amla against arsenic induced oxidative stress and apoptosis in thymocytes of mice. METHODS: Mice were exposed to arsenic (sodium arsenite 3 mg/kg body weight p.o.) or amla (500 mg/kg body weight p.o.) or simultaneously with arsenic and amla for 28 days. The antioxidant enzyme assays were carried out using spectrophotometer and generation of ROS, apoptotic parameters, change in cell cycle were carried out using flow cytometer following the standard protocols. RESULTS: Arsenic exposure to mice caused a significant increase in the lipid peroxidation, ROS production and decreased cell viability, levels of reduced glutathione, the activity of superoxide dismutase, catalase, cytochrome c oxidase and mitochondrial membrane potential in the thymus as compared to controls. Increased activity of caspase-3 linked with apoptosis assessed by the cell cycle analysis and annexin V/PI binding was also observed in mice exposed to arsenic as compared to controls. Co-treatment with arsenic and amla decreased the levels of lipid peroxidation, ROS production, activity of caspase-3, apoptosis and increased cell viability, levels of antioxidant enzymes, cytochrome c oxidase and mitochondrial membrane potential as compared to mice treated with arsenic alone. CONCLUSIONS: The results of the present study exhibits that arsenic induced oxidative stress and apoptosis significantly protected by co-treatment with amla that could be due to its strong antioxidant potential.

RESUMO

Background: Given the underutilization of contraception in India, this study was undertaken to gauge cisgender female clients' knowledge of, attitudes toward, and barriers to contraceptive usage in North India. Methodology: The present study was done at a tertiary care Institute in North India, where 209 structured interviews were conducted with cisgender female patients attending the outpatient department. One-way chi-square tests for independence, Kruskal-Wallis test, and Wilcoxon test were applied to quantitative data. Themes from qualitative questions were coded and analyzed. Results: Differences in awareness among contraceptives were found to be highly statistically significant (H (9) = 1022.3, p < 2.2 e-16). Friends or colleagues comprised the predominant information source for most contraceptive methods. Participants' contraceptive usage was low, with 27.27% stating no prior use and 47.47% indicating occasional use (X2 (3, N = 198) = 66.121, p < 2.89 e-14). Lack of perceived need, concern for side effects, fear and desire for children were top reasons for non-use of contraceptive methods. Majority of the participants (79.45%) expressed comfort speaking with their spouse about contraception, 47.18% with a medical provider, 32.82% with friends, 15.38% with family, 2.05% with a health educator, and 3.59% with no one. Participants indicated little prior contraceptive counseling experience. Conclusion: Our study shows differential levels of awareness, usage, and barriers on contraceptive methods among participants. Results also suggest the importance of spouses and friends in clients' contraceptive decision-making process and their limited counseling experience with health care providers.

RESUMO

Background: There are conflicting reports on status of ovarian function after hysterectomy and opportunistic salpingectomy in premenopausal women. The present study was undertaken to understand the effect of salpingectomy done at the time of hysterectomy on ovarian reserve and function as measured by serum AMH and FSH levels before and after the surgery. Methods: This was a prospective study conducted on 60 women who underwent hysterectomy at our tertiary care centre, Shri Guru Ram Rai Institute of medical and health sciences, Dehradun, from January 2020 to September 2021. Serum AMH and FSH levels were monitored preoperatively and 3 months postoperatively in patients undergoing hysterectomy with bilateral salpingectomy and hysterectomy without salpingectomy. Results: The mean age of the patients was 41.83 yrs in group 1 and 43.73 yrs in group 2 [p value = 0.078]. Most common indication of hysterectomy was AUB-L in both the groups (86% and 80%, respectively). Mean operative time was 115.50 min in group 1 and 114.40 min in group 2 [p value = 0.823]. Mean intra-operative blood loss was 214 ml in group 1 and 199.33 ml in group 2 [p value = 0.087]. Serum AMH and FSH were insignificantly decreased in both the groups post-operatively after 3 months, and the difference between both groups was also not statistically significant. Conclusion: Salpingectomy done at the time of hysterectomy for benign indications with preservation of ovaries did not have any short-term adverse effects on ovarian reserve and function.

RESUMO

Hemoglobin D (HbD) disease was identified in 31 samples from 15 families out of the 2560 samples (1.20%) analyzed for variant Hbs. There were five patients with HbSD disease, three with HbDß disease, and the remaining 23 were HbD trait. Patients with HbSD disease had a variable clinical presentation with a pair of siblings being transfusion dependent although the age of first blood transfusion was different in the two patients. The one with high HbF started transfusions much later. None of them had symptoms related to sickling. Patients with HbDß also had a variable presentation with only one of them being transfusion-dependent. All patients with HbSD and HbDß disease were started on hydroxyurea. Persons with HbD trait were asymptomatic with half of them having normal Hb. The remaining half had mild microcytic hypochromic anemia. All the families with HbD disease were natives of this region and not migrants from other states. Although HbD disease has not been reported from this region in previous studies, clinicians need to be aware of this entity as it can give rise to symptomatic disease in some cases if associated with beta-thalassemia or sickle cell trait.
